### Instruction: retrieve labels for this: Anarchism is a political philosophy that advocates self-governed societies based on voluntary institutions. These are often described as stateless societies, although several authors have defined them more specifically as institutions based on non-hierarchical or free associations. Anarchism holds the state to be undesirable, unnecessary and harmful.While opposition to the state is central, anarchism specifically entails opposing authority or hierarchical organisation in the conduct of all human relations. Anarchism is usually considered a far-left ideology and much of anarchist economics and anarchist legal philosophy reflects anti-authoritarian interpretations of communism, collectivism, syndicalism, mutualism or participatory economics.Anarchism does not offer a fixed body of doctrine from a single particular world view, instead fluxing and flowing as a philosophy. Many types and traditions of anarchism exist, not all of which are mutually exclusive. Anarchist schools of thought can differ fundamentally, supporting anything from extreme individualism to complete collectivism. Strains of anarchism have often been divided into the categories of social and individualist anarchism or similar dual classifications. == Etymology and terminology == The word "anarchism" is composed from the word "anarchy" and the suffix -ism, themselves derived respectively from the Greek ἀναρχία, i.e. anarchy (from ἄναρχος, anarchos, meaning "one without rulers"; from the privative prefix ἀν- (an-, i.e. "without") and ἀρχός, archos, i.e. "leader", "ruler"; (cf. archon or ἀρχή, arkhē, i.e. "authority", "sovereignty", "realm", "magistracy")) and the suffix -ισμός or -ισμα (-ismos, -isma, from the verbal infinitive suffix -ίζειν, -izein). The first known use of this word was in 1539. Various factions within the French Revolution labelled opponents as anarchists (as Maximilien Robespierre did the Hébertists) although few shared many views of later anarchists. There would be many revolutionaries of the early nineteenth century who contributed to the anarchist doctrines of the next generation, such as William Godwin and Wilhelm Weitling, but they did not use the word "anarchist" or "anarchism" in describing themselves or their beliefs.The first political philosopher to call himself an anarchist was Pierre-Joseph Proudhon, marking the formal birth of anarchism in the mid-nineteenth century. Since the 1890s and beginning in France, the term "libertarianism" has often been used as a synonym for anarchism and was used almost exclusively in this sense until the 1950s in the United States, though its use as a synonym is still common outside the United States. On the other hand, some use libertarianism to refer to individualistic free market philosophy only, referring to free market anarchism as libertarian anarchism. == History == === Origins === The earliest anarchist themes can be found in the 6th century BC among the works of Taoist philosopher Laozi and in later centuries by Zhuangzi and Bao Jingyan. Zhuangzi's philosophy has been described by various sources as anarchist. Zhuangzi wrote: "A petty thief is put in jail. A great brigand becomes a ruler of a Nation". Diogenes of Sinope and the Cynics as well as their contemporary Zeno of Citium, the founder of Stoicism, also introduced similar topics. Jesus is sometimes considered the first anarchist in the Christian anarchist tradition. Georges Lechartier wrote: "The true founder of anarchy was Jesus Christ and [...] the first anarchist society was that of the apostles". In early Islamic history, some manifestations of anarchic thought are found during the Islamic civil war over the Caliphate, where the Kharijites insisted that the imamate is a right for each individual within the Islamic society.The French Renaissance political philosopher Étienne de La Boétie wrote in his most famous work the Discourse on Voluntary Servitude what some historians consider an important anarchist precedent. The radical Protestant Christian Gerrard Winstanley and his group the Diggers are cited by various authors as proposing anarchist social measures in the 17th century in England. The term "anarchist" first entered the English language in 1642 during the English Civil War as a term of abuse, used by Royalists against their Roundhead opponents. By the time of the French Revolution, some such as the Enraged Ones began to use the term positively in opposition to Jacobin centralisation of power, seeing "revolutionary government" as oxymoronic. By the turn of the 19th century, the English word "anarchism" had lost its initial negative connotation.Modern anarchism emerged from the secular or religious thought of the Enlightenment, particularly Jean-Jacques Rousseau's arguments for the moral centrality of freedom.As part of the political turmoil of the 1790s in the wake of the French Revolution, William Godwin developed the first expression of modern anarchist thought. According to Peter Kropotkin, Godwin was "the first to formulate the political and economical conceptions of anarchism, even though he did not give that name to the ideas developed in his work" while Godwin attached his anarchist ideas to an early Edmund Burke. Godwin is generally regarded as the founder of the school of thought known as philosophical anarchism. He argued in Political Justice (1793) that government has an inherently malevolent influence on society and that it perpetuates dependency and ignorance. He thought that the spread of the use of reason to the masses would eventually cause government to wither away as an unnecessary force. Although he did not accord the state with moral legitimacy, he was against the use of revolutionary tactics for removing the government from power. Rather, he advocated for its replacement through a process of peaceful evolution.His aversion to the imposition of a rules-based society led him to denounce as a manifestation of the people's "mental enslavement" the foundations of law, property rights and even the institution of marriage. He considered the basic foundations of society as constraining the natural development of individuals to use their powers of reasoning to arrive at a mutually beneficial method of social organisation. In each case, government and its institutions are shown to constrain the development of our capacity to live wholly in accordance with the full and free exercise of private judgement. The French Pierre-Joseph Proudhon is regarded as the first self-proclaimed anarchist, a label he adopted in his groundbreaking work What is Property?, published in 1840. It is for this reason that some claim Proudhon as the founder of modern anarchist theory. He developed the theory of spontaneous order in society, where organisation emerges without a central coordinator imposing its own idea of order against the wills of individuals acting in their own interests. His famous quote on the matter is "Liberty is the mother, not the daughter, of order". In What is Property?, Proudhon answers with the famous accusation "Property is theft". In this work, he opposed the institution of decreed "property" (propriété), where owners have complete rights to "use and abuse" their property as they wish. He contrasted this with what he called "possession", or limited ownership of resources and goods only while in more or less continuous use. However, Proudhon later added that "Property is Liberty" and argued that it was a bulwark against state power. His opposition to the state, organised religion and certain capitalist practices inspired subsequent anarchists and made him one of the leading social thinkers of his time. The anarcho-communist Joseph Déjacque was the first person to describe himself as "libertarian". Unlike Proudhon, he argued that "it is not the product of his or her labour that the worker has a right to, but to the satisfaction of his or her needs, whatever may be their nature". In 1844, the post-Hegelian philosopher Max Stirner published in Germany the book, The Ego and Its Own, which would later be considered an influential early text of individualist anarchism. French anarchists active in the 1848 Revolution included Anselme Bellegarrigue, Ernest Coeurderoy, Joseph Déjacque and Proudhon himself. === First International and the Paris Commune === In Europe, harsh reaction followed the revolutions of 1848, during which ten countries had experienced brief or long-term social upheaval as groups carried out nationalist uprisings. After most of these attempts at systematic change ended in failure, conservative elements took advantage of the divided groups of socialists, liberals and nationalists along with anarchists to prevent further revolt. In Spain, Ramón de la Sagra established the anarchist journal El Porvenir in La Coruña in 1845 which was inspired by Proudhon's ideas. The Catalan politician Francesc Pi i Margall became the principal translator of Proudhon's works into Spanish and later briefly became President of Spain in 1873 while being the leader of the Federal Democratic Republican Party. According to George Woodcock: "These translations were to have a profound and lasting effect on the development of Spanish anarchism after 1870, but before that time Proudhonian ideas, as interpreted by Pi, already provided much of the inspiration for the federalist movement which sprang up in the early 1860's". According to the Encyclopædia Britannica: "During the Spanish revolution of 1873, Pi y Margall attempted to establish a decentralised, or "cantonalist," political system on Proudhonian lines".In 1864, the International Workingmen's Association (sometimes called the First International) united diverse revolutionary currents including French followers of Proudhon, Blanquists, Philadelphes, English trade unionists, socialists and social democrats. Due to its links to active workers' movements, the International became a significant organisation. Karl Marx became a leading figure in the International and a member of its General Council. Proudhon's followers, the mutualists, opposed Marx's state socialism, advocating political abstentionism and small property holdings. Woodcock also reports that the American individualist anarchists Lysander Spooner and William Batchelder Greene had been members of the First International. In 1868, following their unsuccessful participation in the League of Peace and Freedom (LPF) Russian revolutionary Mikhail Bakunin and his collectivist anarchist associates joined the First International, which had decided not to get involved with the LPF. They allied themselves with the federalist socialist sections of the International, who advocated the revolutionary overthrow of the state and the collectivisation of property. At first, the collectivists worked with the Marxists to push the First International in a more revolutionary socialist direction. Subsequently, the International became polarised into two camps, with Marx and Bakunin as their respective figureheads. Bakunin characterised Marx's ideas as centralist and predicted that if a Marxist party came to power, its leaders would simply take the place of the ruling class they had fought against.Anarchist historian George Woodcock reports: "The annual Congress of the International had not taken place in 1870 owing to the outbreak of the Paris Commune, and in 1871 the General Council called only a special conference in London. One delegate was able to attend from Spain and none from Italy, while a technical excuse – that they had split away from the Fédération Romande – was used to avoid inviting Bakunin's Swiss supporters. Thus only a tiny minority of anarchists was present, and the General Council's resolutions passed almost unanimously. Most of them were clearly directed against Bakunin and his followers". In 1872, the conflict climaxed with a final split between the two groups at the Hague Congress, where Bakunin and James Guillaume were expelled from the International and its headquarters were transferred to New York. In response, the federalist sections formed their own International at the St. Imier Congress, adopting a revolutionary anarchist programme.The Paris Commune was a government that briefly ruled Paris from 18 March (more formally, from 28 March) to 28 May 1871. The Commune was the result of an uprising in Paris after France was defeated in the Franco-Prussian War. Anarchists participated actively in the establishment of the Paris Commune. They included Louise Michel, the Reclus brothers (Élie Reclus and Élisée Reclus) and Eugene Varlin (the latter murdered in the repression afterwards). As for the reforms initiated by the Commune, such as the re-opening of workplaces as co-operatives, anarchists can see their ideas of associated labour beginning to be realised. Moreover, the Commune's ideas on federation obviously reflected the influence of Proudhon on French radical ideas. The Commune's vision of a communal France based on a federation of delegates bound by imperative mandates issued by their electors and subject to recall at any moment echoes Bakunin's and Proudhon's ideas (Proudhon, like Bakunin, had argued in favour of the "implementation of the binding mandate" in 1848 and for federation of communes), thus both economically and politically the Paris Commune was heavily influenced by anarchist ideas. George Woodcock states that "a notable contribution to the activities of the Commune and particularly to the organization of public services was made by members of various anarchist factions, including the mutualists Courbet, Longuet, and Vermorel, the libertarian collectivists Varlin, Malon, and Lefrangais, and the bakuninists Elie and Elisée Reclus and Louise Michel". === Organised labour === The anti-authoritarian sections of the First International were the precursors of the anarcho-syndicalists, seeking to "replace the privilege and authority of the State" with the "free and spontaneous organization of labour". In 1886, the Federation of Organized Trades and Labor Unions of the United States and Canada unanimously set 1 May 1886 as the date by which the eight-hour work day would become standard. In response, unions across the United States prepared a general strike in support of the event. On 3 May, a fight broke out in Chicago when strikebreakers attempted to cross the picket line and two workers died when police opened fire upon the crowd. The next day on 4 May, anarchists staged a rally at Chicago's Haymarket Square. A bomb was thrown by an unknown party near the conclusion of the rally, killing an officer. In the ensuing panic, police opened fire on the crowd and each other. Seven police officers and at least four workers were killed. Eight anarchists directly and indirectly related to the organisers of the rally were arrested and charged with the murder of the deceased officer. The men became international political celebrities among the labour movement. Four of the men were executed and a fifth committed suicide prior to his own execution. The incident became known as the Haymarket affair and was a setback for the labour movement and the struggle for the eight-hour day. In 1890, a second attempt—this time international in scope—to organise for the eight-hour day was made. The event also had the secondary purpose of memorialising workers killed as a result of the Haymarket affair. Although it had initially been conceived as a once-off event, by the following year the celebration of International Workers' Day on May Day had become firmly established as an international worker's holiday.In 1907, the International Anarchist Congress of Amsterdam gathered delegates from 14 different countries, among which were important figures of the anarchist movement, including Errico Malatesta, Pierre Monatte, Luigi Fabbri, Benoît Broutchoux, Emma Goldman, Rudolf Rocker and Christiaan Cornelissen. Various themes were treated during the Congress, in particular concerning the organisation of the anarchist movement, popular education issues, the general strike or antimilitarism. A central debate concerned the relation between anarchism and syndicalism (or trade unionism). Malatesta and Monatte were in particular disagreement themselves on this issue as the latter thought that syndicalism was revolutionary and would create the conditions of a social revolution while Malatesta did not consider syndicalism by itself sufficient. He thought that the trade union movement was reformist and even conservative, citing as essentially bourgeois and anti-worker the phenomenon of professional union officials. Malatesta warned that the syndicalists aims were in perpetuating syndicalism itself, whereas anarchists must always have anarchy as their end and consequently refrain from committing to any particular method of achieving it.In 1881, the Spanish Workers Federation was the first major anarcho-syndicalist movement—anarchist trade union federations were of special importance in Spain. The most successful was the Confederación Nacional del Trabajo (National Confederation of Labour, CNT), founded in 1910. Before the 1940s, the CNT was the major force in Spanish working class politics, attracting 1.58 million members at one point and playing a major role in the Spanish Civil War. The CNT was affiliated with the International Workers Association, a federation of anarcho-syndicalist trade unions founded in 1922, with delegates representing two million workers from 15 countries in Europe and Latin America. In Latin America in particular, "[t]he anarchists quickly became active in organising craft and industrial workers throughout South and Central America, and until the early 1920s most of the trade unions in Mexico, Brazil, Peru, Chile, and Argentina were anarcho-syndicalist in general outlook; the prestige of the Spanish C.N.T. as a revolutionary organisation was undoubtedly to a great extent responsible for this situation. The largest and most militant of these organisations was the Federación Obrera Regional Argentina [...] it grew quickly to a membership of nearly a quarter of a million, which dwarfed the rival socialdemocratic unions". === Propaganda of the deed and illegalism === Some anarchists, such as Johann Most, advocated publicising violent acts of retaliation against counter-revolutionaries because "we preach not only action in and for itself, but also action as propaganda". Scholars such as Beverly Gage contend that this was not advocacy of mass murder, but targeted killings of members of the ruling class at times when such actions might garner sympathy from the population, such as during periods of heightened government repression or labor conflicts where workers were killed. However, Most himself once boasted that "the existing system will be quickest and most radically overthrown by the annihilation of its exponents. Therefore, massacres of the enemies of the people must be set in motion". Most is best known for a pamphlet published in 1885, The Science of Revolutionary Warfare, a how-to manual on the subject of making explosives based on knowledge he acquired while working at an explosives plant in New Jersey.By the 1880s, people inside and outside the anarchist movement began to use the slogan, "propaganda of the deed" to refer to individual bombings, regicides and tyrannicides. From 1905 onwards, the Russian counterparts of these anti-syndicalist anarchist-communists become partisans of economic terrorism and illegal "expropriations". Illegalism as a practice emerged and within it "[t]he acts of the anarchist bombers and assassins ("propaganda by the deed") and the anarchist burglars ("individual reappropriation") expressed their desperation and their personal, violent rejection of an intolerable society. Moreover, they were clearly meant to be exemplary invitations to revolt". France's Bonnot Gang was the most famous group to embrace illegalism. However, important figures in the anarchist movement distanced themselves from such individual acts as soon as 1887. Peter Kropotkin thus wrote that year in Le Révolté that "a structure based on centuries of history cannot be destroyed with a few kilos of dynamite". A variety of anarchists advocated the abandonment of these sorts of tactics in favour of collective revolutionary action, for example through the trade union movement. The anarcho-syndicalist Fernand Pelloutier argued in 1895 for renewed anarchist involvement in the labour movement on the basis that anarchism could do very well without "the individual dynamiter".State repression (including the infamous 1894 French lois scélérates) of the anarchist and labour movements following the few successful bombings and assassinations may have contributed in the first place to the abandonment of these kinds of tactics, although reciprocally state repression may have played a role in these isolated acts. The dismemberment of the French socialist movement into many groups and—following the suppression of the 1871—Paris Commune the execution and exile of many communards to penal colonies favoured individualist political expression and acts.Numerous heads of state were assassinated between 1881 and 1914 by members of the anarchist movement, including Tsar Alexander II of Russia, President Sadi Carnot of France, Empress Elisabeth of Austria, King Umberto I of Italy, President William McKinley of the United States, King Carlos I of Portugal and King George I of Greece. McKinley's assassin Leon Czolgosz claimed to have been influenced by anarchist and feminist Emma Goldman. === Russian Revolution and other uprisings of the 1910s === Anarchists participated alongside the Bolsheviks in both February and October revolutions and were initially enthusiastic about the Bolshevik revolution. However, following a political falling out with the Bolsheviks by the anarchists and other left-wing opposition the conflict culminated in the 1921 Kronstadt rebellion, which the new government repressed. Anarchists in central Russia were either imprisoned, driven underground or joined the victorious Bolsheviks; the anarchists from Petrograd and Moscow fled to Ukraine. In the Free Territory, they fought in the civil war against the Whites (a grouping of monarchists and other opponents of the October Revolution) and then the Bolsheviks as part of the Revolutionary Insurrectionary Army of Ukraine led by Nestor Makhno, who established an anarchist society in the region for a number of months. Expelled American anarchists Emma Goldman and Alexander Berkman were among those agitating in response to Bolshevik policy and the suppression of the Kronstadt uprising, before they left Russia. Both wrote accounts of their experiences in Russia, criticising the amount of control the Bolsheviks exercised. For them, Bakunin's predictions about the consequences of Marxist rule that the rulers of the new "socialist" Marxist state would become a new elite had proved all too true.The victory of the Bolsheviks in the October Revolution and the resulting Russian Civil War did serious damage to anarchist movements internationally. Many workers and activists saw Bolshevik success as setting an example and communist parties grew at the expense of anarchism and other socialist movements. In France and the United States, for example, members of the major syndicalist movements of the General Confederation of Labour and Industrial Workers of the World (IWW) left the organisations and joined the Communist International.The revolutionary wave of 1917–1923 saw the active participation of anarchists in varying degrees of protagonism. In the German uprising known as the German Revolution of 1918–1919 which established the Bavarian Soviet Republic, the anarchists Gustav Landauer, Silvio Gesell and Erich Mühsam had important leadership positions within the revolutionary councilist structures. In the Italian events known as the biennio rosso, the anarcho-syndicalist trade union Unione Sindacale Italiana "grew to 800,000 members and the influence of the Italian Anarchist Union (20,000 members plus Umanita Nova, its daily paper) grew accordingly [...] Anarchists were the first to suggest occupying workplaces. In the Mexican Revolution, the Mexican Liberal Party was established and during the early 1910s it led a series of military offensives leading to the conquest and occupation of certain towns and districts in Baja California with the leadership of anarcho-communist Ricardo Flores Magón.In Paris, the Dielo Truda group of Russian anarchist exiles, which included Nestor Makhno, concluded that anarchists needed to develop new forms of organisation in response to the structures of Bolshevism. Their 1926 manifesto, called the Organisational Platform of the General Union of Anarchists (Draft), was supported. Platformist groups active today include the Workers Solidarity Movement in Ireland and the North Eastern Federation of Anarchist Communists of North America. Synthesis anarchism emerged as an organisational alternative to platformism that tries to join anarchists of different tendencies under the principles of anarchism without adjectives. In the 1920s, this form found as its main proponents Volin and Sebastien Faure. It is the main principle behind the anarchist federations grouped around the contemporary global International of Anarchist Federations. === Conflicts with European fascist regimes === In the 1920s and 1930s, the rise of fascism in Europe transformed anarchism's conflict with the state. Italy saw the first struggles between anarchists and Benito Mussolini's fascists. Italian anarchists played a key role in the anti-fascist organisation Arditi del Popolo, which was strongest in areas with anarchist traditions and achieved some success in their activism, such as repelling Blackshirts in the anarchist stronghold of Parma in August 1922. The veteran Italian anarchist Luigi Fabbri was one of the first critical theorists of fascism, describing it as "the preventive counter-revolution". In France, where the far-right leagues came close to insurrection in the February 1934 riots, anarchists divided over a united front policy.Anarchists in France and Italy were active in the Resistance during World War II. In Germany, the anarchist Erich Mühsam was arrested on charges unknown in the early morning hours of 28 February 1933, within a few hours after the Reichstag fire in Berlin. Joseph Goebbels, the Nazi propaganda minister, labelled him as one of "those Jewish subversives". Over the next seventeen months, he would be imprisoned in the concentration camps at Sonnenburg, Brandenburg and finally, Oranienburg. On 2 February 1934, Mühsam was transferred to the concentration camp at Oranienburg when finally on the night of 9 July 1934, Mühsam was tortured and murdered by the guards, his battered corpse found hanging in a latrine the next morning. === Spanish Revolution === In Spain, the national anarcho-syndicalist trade union CNT initially refused to join a popular front electoral alliance and abstention by CNT supporters led to a right-wing election victory. In 1936, the CNT changed its policy and anarchist votes helped bring the popular front back to power. Months later, conservative members of the military, with the support of minority extreme-right parties, responded with an attempted coup, causing the Spanish Civil War (1936–1939). In response to the army rebellion, an anarchist-inspired movement of peasants and workers, supported by armed militias, took control of Barcelona and of large areas of rural Spain where they collectivised the land. However, the anarchists were losing ground even before the fascist victory in 1939 in a bitter struggle with the Stalinists, who controlled much of the distribution of military aid to the Republicans cause from the Soviet Union. According to Noam Chomsky, "the communists were mainly responsible for the destruction of the Spanish anarchists. Not just in Catalonia—the communist armies mainly destroyed the collectives elsewhere. The communists basically acted as the police force of the security system of the Republic and were very much opposed to the anarchists, partially because Stalin still hoped at that time to have some kind of pact with Western countries against Adolf Hitler. That failed and Stalin withdrew the support to the Republic. They even withdrew the Spanish gold reserves". The events known as the Spanish Revolution was a workers' social revolution that began during the outbreak of the Spanish Civil War in 1936 and resulted in the widespread implementation of anarchist and more broadly libertarian socialist organisational principles throughout various portions of the country for two to three years, primarily Catalonia, Aragon, Andalusia and parts of Levante. Much of Spain's economy was put under worker control and in anarchist strongholds like Catalonia the figure was as high as 75%, but lower in areas with heavy Communist Party of Spain influence as the Soviet-allied party actively resisted attempts at collectivisation enactment. Factories were run through worker committees, agrarian areas became collectivised and run as libertarian communes. Anarchist historian Sam Dolgoff estimated that about eight million people participated directly or at least indirectly in the Spanish Revolution, which he claimed "came closer to realising the ideal of the free stateless society on a vast scale than any other revolution in history". Spanish Communist Party-led troops suppressed the collectives and persecuted both dissident Marxists and anarchists. The prominent Italian anarchist Camillo Berneri, who volunteered to fight against Francisco Franco was killed instead in Spain by gunmen associated with the Spanish Communist Party. The city of Madrid was turned over to the Francoist forces by the last non-francoist mayor of the city, the anarchist Melchor Rodríguez García. === Post-war years === Anarchism sought to reorganise itself after the war and in this context the organisational debate between synthesis anarchism and platformism took importance once again especially in the anarchist movements of Italy and France. The Mexican Anarchist Federation was established in 1945 after the Anarchist Federation of the Centre united with the Anarchist Federation of the Federal District. In the early 1940s, the Antifascist International Solidarity and the Federation of Anarchist Groups of Cuba merged into the large national organisation Asociación Libertaria de Cuba (Cuban Libertarian Association). From 1944 to 1947, the Bulgarian Anarchist Communist Federation reemerged as part of a factory and workplace committee movement, but was repressed by the new Communist regime. In 1945 in France the Fédération Anarchiste and the anarchosyndicalist trade union Confédération nationale du travail was established in the next year while the also synthesist Federazione Anarchica Italiana was founded in Italy. Korean anarchists formed the League of Free Social Constructors in September 1945 and in 1946 the Japanese Anarchist Federation was founded. An International Anarchist Congress with delegates from across Europe was held in Paris in May 1948. After World War II, an appeal in the Fraye Arbeter Shtime detailing the plight of German anarchists and called for Americans to support them. By February 1946, the sending of aid parcels to anarchists in Germany was a large-scale operation. The Federation of Libertarian Socialists was founded in Germany in 1947 and Rudolf Rocker wrote for its organ, Die Freie Gesellschaft, which survived until 1953. In 1956, the Uruguayan Anarchist Federation was founded. In 1955, the Anarcho-Communist Federation of Argentina renamed itself as the Argentine Libertarian Federation. The Syndicalist Workers' Federation (SWF) was a syndicalist group in active in post-war Britain, and one of Solidarity Federation's earliest predecessors. It was formed in 1950 by members of the dissolved Anarchist Federation of Britain (AFB). Unlike the AFB, which was influenced by anarcho-syndicalist ideas but ultimately not syndicalist itself, the SWF decided to pursue a more definitely syndicalist, worker-centred strategy from the outset.Anarchism continued to influence important literary and intellectual personalities of the time, such as Albert Camus, Herbert Read, Paul Goodman, Dwight Macdonald, Allen Ginsberg, George Woodcock, Leopold Kohr, Julian Beck, John Cage and the French Surrealist group led by André Breton, which now openly embraced anarchism and collaborated in the Fédération Anarchiste.Anarcho-pacifism became influential in the Anti-nuclear movement and anti war movements of the time as can be seen in the activism and writings of the English anarchist member of Campaign for Nuclear Disarmament Alex Comfort or the similar activism of the American catholic anarcho-pacifists Ammon Hennacy and Dorothy Day. Anarcho-pacifism became a "basis for a critique of militarism on both sides of the Cold War". The resurgence of anarchist ideas during this period is well documented in Robert Graham's Anarchism: A Documentary History of Libertarian Ideas, Volume Two: The Emergence of the New Anarchism (1939–1977). === Contemporary anarchism === A surge of popular interest in anarchism occurred in western nations during the 1960s and 1970s. Anarchism was influential in the Counterculture of the 1960s and anarchists actively participated in the late sixties students and workers revolts. In 1968, in Carrara, Italy the International of Anarchist Federations was founded during an international anarchist conference held there in 1968 by the three existing European federations of France (the Fédération Anarchiste), the Federazione Anarchica Italiana of Italy and the Iberian Anarchist Federation as well as the Bulgarian federation in French exile.In the United Kingdom in the 1970s, this was associated with the punk rock movement as exemplified by bands such as Crass and the Sex Pistols. The housing and employment crisis in most of Western Europe led to the formation of communes and squatter movements like that of Barcelona, Spain. In Denmark, squatters occupied a disused military base and declared the Freetown Christiania, an autonomous haven in central Copenhagen. Since the revival of anarchism in the mid-20th century, a number of new movements and schools of thought emerged. Although feminist tendencies have always been a part of the anarchist movement in the form of anarcha-feminism, they returned with vigour during the second wave of feminism in the 1960s. Anarchist anthropologist David Graeber and anarchist historian Andrej Grubacic have posited a rupture between generations of anarchism, with those "who often still have not shaken the sectarian habits" of the 19th century contrasted with the younger activists who are "much more informed, among other elements, by indigenous, feminist, ecological and cultural-critical ideas" and who by the turn of the 21st century formed "by far the majority" of anarchists.Since the 1980s, anarchism has grown into a strong political force in Latin America, with the development of Fejuve (1979), CIPO-RFM (1980s), Zapatistas (1994), Horizontilidad (2001) and the Oaxaca Uprising (2006). Around the turn of the 21st century, anarchism grew in popularity and influence as part of the anti-war, anti-capitalist, and anti-globalisation movements. Anarchists became known for their involvement in protests against the meetings of the World Trade Organization (WTO), Group of Eight (G8) and the World Economic Forum (WEF). Some anarchist factions at these protests engaged in rioting, property destruction, and violent confrontations with police. These actions were precipitated by ad hoc, leaderless, anonymous cadres known as black blocs—other organisational tactics pioneered in this time include security culture, affinity groups and the use of decentralised technologies such as the internet. A significant event of this period was the confrontations at WTO conference in Seattle in 1999. According to anarchist scholar Simon Critchley, "contemporary anarchism can be seen as a powerful critique of the pseudo-libertarianism of contemporary neo-liberalism [...] One might say that contemporary anarchism is about responsibility, whether sexual, ecological or socio-economic; it flows from an experience of conscience about the manifold ways in which the West ravages the rest; it is an ethical outrage at the yawning inequality, impoverishment and disenfranchisment that is so palpable locally and globally". International anarchist federations in existence include the International of Anarchist Federations, the International Workers' Association and International Libertarian Solidarity. The largest organised anarchist movement today is in Spain in the form of the Confederación General del Trabajo (CGT) and the CNT. CGT membership was estimated at around 100,000 for 2003.Anarchist ideas have been influential in the development of the Democratic Federation of Northern Syria (DFNS), more commonly known as Rojava, a de facto autonomous region in northern Syria. Abdullah Öcalan—a founding member of the Kurdistan Workers' Party (PKK) who is currently imprisoned in Turkey—is an iconic and popular figure in the DFNS whose ideas shaped the region's society and politics. While in prison, Öcalan corresponded with (and was influenced by) Murray Bookchin, an anarcho-communist theorist and philosopher who developed Communalism and libertarian municipalism. Modelled after Bookchin's ideas, Öcalan developed the theory of democratic confederalism. In March 2005, he issued his "Declaration of Democratic Confederalism in Kurdistan", calling upon citizens "to stop attacking the government and instead create municipal assemblies, which he called 'democracy without the state'". == Anarchist schools of thought == Anarchist schools of thought had been generally grouped in two main historical traditions, individualist anarchism and social anarchism, which have some different origins, values and evolution. The individualist wing of anarchism emphasises negative liberty, i.e. opposition to state or social control over the individual, while those in the social wing emphasise positive liberty to achieve one's potential and argue that humans have needs that society ought to fulfil, "recognising equality of entitlement". In a chronological and theoretical sense, there are classical—those created throughout the 19th century—and post-classical anarchist schools—those created since the mid-20th century and after. Beyond the specific factions of anarchist thought is philosophical anarchism, which embodies the theoretical stance that the state lacks moral legitimacy without accepting the imperative of revolution to eliminate it. A component especially of individualist anarchism philosophical anarchism may accept the existence of a minimal state as unfortunate, and usually temporary, "necessary evil" but argue that citizens do not have a moral obligation to obey the state when its laws conflict with individual autonomy. One reaction against sectarianism within the anarchist milieu was "anarchism without adjectives", a call for toleration first adopted by Fernando Tarrida del Mármol in 1889 in response to the "bitter debates" of anarchist theory at the time. In abandoning the hyphenated anarchisms (i.e. collectivist-, communist-, mutualist– and individualist-anarchism), it sought to emphasise the anti-authoritarian beliefs common to all anarchist schools of thought. === Mutualism === Mutualism began in 18th-century English and French labour movements before taking an anarchist form associated with Pierre-Joseph Proudhon in France and others in the United States. Proudhon proposed spontaneous order, whereby organisation emerges without central authority, a "positive anarchy" where order arises when everybody does "what he wishes and only what he wishes" and where "business transactions alone produce the social order." Proudhon distinguished between ideal political possibilities and practical governance. For this reason, much in contrast to some of his theoretical statements concerning ultimate spontaneous self-governance, Proudhon was heavily involved in French parliamentary politics and allied himself not with anarchist but socialist factions of workers' movements and, in addition to advocating state-protected charters for worker-owned cooperatives, promoted certain nationalisation schemes during his life of public service. Mutualist anarchism is concerned with reciprocity, free association, voluntary contract, federation, and credit and currency reform. According to the American mutualist William Batchelder Greene, each worker in the mutualist system would receive "just and exact pay for his work; services equivalent in cost being exchangeable for services equivalent in cost, without profit or discount". Mutualism has been retrospectively characterised as ideologically situated between individualist and collectivist forms of anarchism. Proudhon first characterised his goal as a "third form of society, the synthesis of communism and property". === Social anarchism === Social anarchism calls for a system with common ownership of means of production and democratic control of all organisations, without any government authority or coercion. It is the largest school of thought in anarchism. Social anarchism rejects private property, seeing it as a source of social inequality (while retaining respect for personal property) and emphasises cooperation and mutual aid. ==== Collectivist anarchism ==== Collectivist anarchism, also referred to as revolutionary socialism or a form of such, is a revolutionary form of anarchism, commonly associated with Mikhail Bakunin and Johann Most. Collectivist anarchists oppose all private ownership of the means of production, instead advocating that ownership be collectivised. This was to be achieved through violent revolution, first starting with a small cohesive group through acts of violence, or propaganda by the deed, which would inspire the workers as a whole to revolt and forcibly collectivise the means of production.However, collectivisation was not to be extended to the distribution of income as workers would be paid according to time worked, rather than receiving goods being distributed "according to need" as in anarcho-communism. This position was criticised by anarchist communists as effectively "uphold[ing] the wages system". Collectivist anarchism arose contemporaneously with Marxism, but opposed the Marxist dictatorship of the proletariat despite the stated Marxist goal of a collectivist stateless society. Anarchist, communist and collectivist ideas are not mutually exclusive—although the collectivist anarchists advocated compensation for labour, some held out the possibility of a post-revolutionary transition to a communist system of distribution according to need. ==== Anarcho-communism ==== Anarcho-communism (also known as anarchist-communism, libertarian communism and occasionally as free communism) is a theory of anarchism that advocates abolition of the state, markets, money, private property (while retaining respect for personal property) and capitalism in favour of common ownership of the means of production, direct democracy and a horizontal network of voluntary associations and workers' councils with production and consumption based on the guiding principle: "From each according to his ability, to each according to his need".Some forms of anarchist communism such as insurrectionary anarchism are strongly influenced by egoism and radical individualism, believing anarcho-communism is the best social system for the realisation of individual freedom. Most anarcho-communists view anarcho-communism as a way of reconciling the opposition between the individual and society.Anarcho-communism developed out of radical socialist currents after the French Revolution but was first formulated as such in the Italian section of the First International. The theoretical work of Peter Kropotkin took importance later as it expanded and developed pro-organisationalist and insurrectionary anti-organisationalist sections. To date, the best known examples of an anarchist communist society (i.e. established around the ideas as they exist today and achieving worldwide attention and knowledge in the historical canon), are the anarchist territories during the Spanish Revolution and the Free Territory during the Russian Revolution. Through the efforts and influence of the Spanish anarchists during the Spanish Revolution within the Spanish Civil War, starting in 1936 anarchist communism existed in most of Aragon, parts of the Levante and Andalusia as well as in the stronghold of anarchist Catalonia before being crushed by the combined forces of the regime that won the war, Hitler, Mussolini, Communist Party of Spain repression (backed by the Soviet Union) as well as economic and armaments blockades from the capitalist countries and the Spanish Republic itself. During the Russian Revolution, anarchists such as Nestor Makhno worked to create and defend—through the Revolutionary Insurrectionary Army of Ukraine—anarcho-communism in the Free Territory of the Ukraine from 1919 before being conquered by the Bolsheviks in 1921. ==== Anarcho-syndicalism ==== Anarcho-syndicalism is a branch of anarchism that focuses on the labour movement. Anarcho-syndicalists view labour unions as a potential force for revolutionary social change, replacing capitalism and the state with a new society democratically self-managed by workers. The basic principles of anarcho-syndicalism are workers' solidarity, direct action and workers' self-management. Anarcho-syndicalists believe that only direct action—that is, action concentrated on directly attaining a goal as opposed to indirect action, such as electing a representative to a government position—will allow workers to liberate themselves. Moreover, anarcho-syndicalists believe that workers' organisations (the organisations that struggle against the wage system, which in anarcho-syndicalist theory will eventually form the basis of a new society) should be self-managing. They should not have bosses or "business agents"—rather, the workers should be able to make all the decisions that affect them themselves. Rudolf Rocker was one of the most popular voices in the anarcho-syndicalist movement. He outlined a view of the origins of the movement, what it sought and why it was important to the future of labour in his 1938 pamphlet Anarcho-Syndicalism. The International Workers Association is an international anarcho-syndicalist federation of various labour unions from different countries. The Spanish CNT played and still plays a major role in the Spanish labour movement. It was also an important force in the Spanish Civil War. === Individualist anarchism === Individualist anarchism refers to several traditions of thought within the anarchist movement that emphasise the individual and their will over any kinds of external determinants such as groups, society, traditions and ideological systems. Individualist anarchism is not a single philosophy, but it instead refers to a group of individualistic philosophies that sometimes are in conflict. In 1793, William Godwin, who has often been cited as the first anarchist, wrote Political Justice, which some consider the first expression of anarchism. Godwin was a philosophical anarchist and from a rationalist and utilitarian basis opposed revolutionary action and saw a minimal state as a present "necessary evil" that would become increasingly irrelevant and powerless by the gradual spread of knowledge. Godwin advocated individualism, proposing that all cooperation in labour be eliminated on the premise that this would be most conducive with the general good. An influential form of individualist anarchism, called "egoism", or egoist anarchism, was expounded by one of the earliest and best-known proponents of individualist anarchism, the German Max Stirner. Stirner's The Ego and Its Own, published in 1844, is a founding text of the philosophy. According to Stirner, the only limitation on the rights of individuals is their power to obtain what they desire, without regard for God, state, or morality. To Stirner, rights were "spooks" in the mind and he held that society does not exist, but "the individuals are its reality". Stirner advocated self-assertion and foresaw unions of egoists, non-systematic associations continually renewed by all parties' support through an act of will, which Stirner proposed as a form of organisation in place of the state. Egoist anarchists argue that egoism will foster genuine and spontaneous union between individuals. "Egoism" has inspired many interpretations of Stirner's philosophy. It was re-discovered and promoted by German philosophical anarchist and homosexual activist John Henry Mackay. Josiah Warren is widely regarded as the first American anarchist, and the four-page weekly paper he edited during 1833, The Peaceful Revolutionist, was the first anarchist periodical published. For American anarchist historian Eunice Minette Schuster, "[i]t is apparent [...] that Proudhonian Anarchism was to be found in the United States at least as early as 1848 and that it was not conscious of its affinity to the Individualist Anarchism of Josiah Warren and Stephen Pearl Andrews [...] William B. Greene presented this Proudhonian Mutualism in its purest and most systematic form". Henry David Thoreau (1817–1862) was an important early influence in individualist anarchist thought in the United States and Europe. Thoreau was an American author, poet, naturalist, tax resister, development critic, surveyor, historian, philosopher and leading transcendentalist. He is best known for his books Walden, a reflection upon simple living in natural surroundings, as well as his essay, Civil Disobedience, an argument for individual resistance to civil government in moral opposition to an unjust state. Benjamin Tucker later fused Stirner's egoism with the economics of Warren and Proudhon in his eclectic influential publication Liberty. From these early influences, individualist anarchism in different countries attracted a small yet diverse following of Bohemian artists and intellectuals, free love and birth control advocates (see anarchism and issues related to love and sex), individualist naturists and nudists (see anarcho-naturism), freethought and anti-clerical activists as well as young anarchist outlaws in what became known as illegalism and individual reclamation (see European individualist anarchism and individualist anarchism in France). These authors and activists included Oscar Wilde, Emile Armand, Han Ryner, Henri Zisly, Renzo Novatore, Miguel Gimenez Igualada, Adolf Brand and Lev Chernyi among others. === Post-classical anarchist schools of thought === Anarchism continues to generate many philosophies and movements, at times eclectic, drawing upon various sources and syncretic, combining disparate concepts to create new philosophical approaches.Insurrectionary anarchism is a revolutionary theory, practice, and tendency within the anarchist movement which emphasises insurrection within anarchist practice. It is critical of formal organisations such as labour unions and federations that are based on a political programme and periodic congresses. Instead, insurrectionary anarchists advocate informal organisation and small affinity group based organisation. Insurrectionary anarchists put value in attack, permanent class conflict and a refusal to negotiate or compromise with class enemies.Green anarchism (or eco-anarchism) is a school of thought within anarchism that emphasises environmental issues, with an important precedent in anarcho-naturism and whose main contemporary currents are anarcho-primitivism and social ecology. Writing from a green anarchist perspective, John Zerzan attributes the ills of today's social degradation to technology and the birth of agricultural civilization. While Layla AbdelRahim argues that "the shift in human consciousness was also a shift in human subsistence strategies, whereby some human animals reinvented their narrative to center murder and predation and thereby institutionalize violence". Thus, according to her, civilization was the result of the human development of technologies and grammar for predatory economics. Language and literacy, she claims, are some of these technologies.Anarcha-feminism (also called anarchist feminism and anarcho-feminism) combines anarchism with feminism. It generally views patriarchy as a manifestation of involuntary coercive hierarchy that should be replaced by decentralised free association. Anarcha-feminists believe that the struggle against patriarchy is an essential part of class struggle, and the anarchist struggle against the state. In essence, the philosophy sees anarchist struggle as a necessary component of feminist struggle and vice versa. L. Susan Brown claims that "as anarchism is a political philosophy that opposes all relationships of power, it is inherently feminist". Anarcha-feminism began with the late 19th-century writings of early feminist anarchists such as Emma Goldman and Voltairine de Cleyre. Anarcho-pacifism is a tendency that rejects violence in the struggle for social change (see non-violence). It developed mostly in the Netherlands, Britain and the United States before and during the Second World War. Christian anarchism is a movement in political theology that combines anarchism and Christianity. Its main proponents included Leo Tolstoy, Dorothy Day, Ammon Hennacy and Jacques Ellul. Religious anarchism refers to a set of related anarchist ideologies that are inspired by the teachings of (organized) religions, but many anarchists have traditionally been skeptical of and opposed to organized religion. Many different religions have served as inspiration for religious forms of anarchism, most notably Christianity as Christian anarchists believe that biblical teachings give credence to anarchist philosophy. Non-Christian forms of religious anarchism include Buddhist anarchism, Jewish anarchism and most recently Neopaganism Synthesis anarchism is a form of anarchism that tries to join anarchists of different tendencies under the principles of anarchism without adjectives. In the 1920s, this form found as its main proponents the anarcho-communists Voline and Sébastien Faure. It is the main principle behind the anarchist federations grouped around the contemporary global International of Anarchist Federations.Platformism is a tendency within the wider anarchist movement based on the organisational theories in the tradition of Dielo Truda's Organisational Platform of the General Union of Anarchists (Draft). The document was based on the experiences of Russian anarchists in the 1917 October Revolution, which led eventually to the victory of the Bolsheviks over the anarchists and other groups. The Platform attempted to address and explain the anarchist movement's failures during the Russian Revolution. Post-left anarchy is a recent current in anarchist thought that promotes a critique of anarchism's relationship to traditional left-wing politics. Some post-leftists seek to escape the confines of ideology in general also presenting a critique of organisations and morality. Influenced by the work of Max Stirner and by the Marxist Situationist International, post-left anarchy is marked by a focus on social insurrection and a rejection of leftist social organisation.Post-anarchism is a theoretical move towards a synthesis of classical anarchist theory and poststructuralist thought, drawing from diverse ideas including post-left anarchy, postmodernism, autonomism, postcolonialism and the Situationist International. Queer anarchism is a form of socialism which suggests anarchism as a solution to the issues faced by the LGBT community, mainly heteronormativity, homophobia, transphobia and biphobia. Anarcho-queer arose during the late 20th century based on the work of Michel Foucault The History of Sexuality. Left-wing market anarchism strongly affirm the classical liberal ideas of self-ownership and free markets while maintaining that taken to their logical conclusions, these ideas support strongly anti-corporatist, anti-hierarchical, pro-labour positions and anti-capitalism in economics and anti-imperialism in foreign policy.Anarcho-capitalism advocates the elimination of the state in favour of self-ownership in a free market. Anarcho-capitalism developed from radical anti-state libertarianism and individualist anarchism, drawing from Austrian School economics, study of law and economics and public choice theory. There is a strong current within anarchism which believes that anarcho-capitalism cannot be considered a part of the anarchist movement due to the fact that anarchism has historically been an anti-capitalist movement and for definitional reasons which see anarchism as incompatible with capitalist forms.Anarcho-transhumanism is a recently new branch of anarchism that takes traditional and modern anarchism, typically drawing from anarcho-syndicalism, left-libertarianism or libertarian soclialism and combines it with transhumanism and post-humanism. It can be described as a "liberal democratic revolution, at its core the idea that people are happiest when they have rational control over their lives. Reason, science, and technology provide one kind of control, slowly freeing us from ignorance, toil, pain, disease and limited lifespans (aging)". Some anarcho-transhumanists might also follow technogaianism. == Internal issues and debates == Anarchism is a philosophy that embodies many diverse attitudes, tendencies and schools of thought and as such disagreement over questions of values, ideology and tactics is common. The compatibility of capitalism, nationalism and religion with anarchism is widely disputed. Similarly, anarchism enjoys complex relationships with ideologies such as Marxism, communism, collectivism, syndicalism/trade unionism and capitalism. Anarchists may be motivated by humanism, divine authority, enlightened self-interest, veganism or any number of alternative ethical doctrines. Phenomena such as civilisation, technology (e.g. within anarcho-primitivism) and the democratic process may be sharply criticised within some anarchist tendencies and simultaneously lauded in others. On a tactical level, while propaganda of the deed was a tactic used by anarchists in the 19th century (e.g. the nihilist movement), some contemporary anarchists espouse alternative direct action methods such as nonviolence, counter-economics and anti-state cryptography to bring about an anarchist society. About the scope of an anarchist society, some anarchists advocate a global one, while others do so by local ones. The diversity in anarchism has led to widely different use of identical terms among different anarchist traditions, which has led to many definitional concerns in anarchist theory. == Topics of interest == Intersecting and overlapping between various schools of thought, certain topics of interest and internal disputes have proven perennial within anarchist theory. === Free love === An important current within anarchism is free love. Free love advocates sometimes traced their roots back to Josiah Warren and to experimental communities, viewed sexual freedom as a clear, direct expression of an individual's sovereignty. Free love particularly stressed women's rights since most sexual laws discriminated against women, see for example marriage laws and anti-birth control measures. The most important American free love journal was Lucifer the Lightbearer (1883–1907), edited by Moses Harman and Lois Waisbrooker, but also there existed Ezra Heywood and Angela Heywood's The Word (1872–1890, 1892–1893). Free Society (1895–1897 as The Firebrand; 1897–1904 as Free Society) was a major anarchist newspaper in the United States at the end of the 19th and beginning of the 20th centuries. The publication advocated free love and women's rights and critiqued "Comstockery"—i.e. censorship of sexual information. Also M. E. Lazarus was an important American individualist anarchist who promoted free love.In New York City's Greenwich Village, bohemian feminists and socialists advocated self-realisation and pleasure for women (and also men) in the here and now. They encouraged playing with sexual roles and sexuality and the openly bisexual radical Edna St. Vincent Millay and the lesbian anarchist Margaret Anderson were prominent among them. Discussion groups organised by the Villagers were frequented by Emma Goldman, among others. Magnus Hirschfeld noted in 1923 that Goldman "has campaigned boldly and steadfastly for individual rights, and especially for those deprived of their rights. Thus it came about that she was the first and only woman, indeed the first and only American, to take up the defence of homosexual love before the general public". Before Goldman, heterosexual anarchist Robert Reitzel (1849–1898) spoke positively of homosexuality from the beginning of the 1890s in his Detroit-based German language journal Der arme Teufel (English: The Poor Devil). In Argentina, anarcha-feminist Virginia Bolten published the newspaper called La Voz de la Mujer (English: The Woman's Voice), which was published nine times in Rosario between 8 January 1896 and 1 January 1897 and was revived briefly in 1901.In Europe, the main propagandist of free love within individualist anarchism was Emile Armand. He proposed the concept of la camaraderie amoureuse to speak of free love as the possibility of voluntary sexual encounter between consenting adults. He was also a consistent proponent of polyamory. In Germany, the Stirnerists Adolf Brand and John Henry Mackay were pioneering campaigners for the acceptance of male bisexuality and homosexuality. Mujeres Libres was an anarchist women's organisation in Spain that aimed to empower working class women. It was founded in 1936 by Lucía Sánchez Saornil, Mercedes Comaposada and Amparo Poch y Gascón and had approximately 30,000 members. The organisation was based on the idea of a "double struggle" for women's liberation and social revolution and argued that the two objectives were equally important and should be pursued in parallel. In order to gain mutual support, they created networks of women anarchists. Lucía Sánchez Saornil was a main founder of the Spanish anarcha-feminist federation Mujeres Libres who was open about her lesbianism. She was published in a variety of literary journals while working under a male pen name, she was able to explore lesbian themes at a time when homosexuality was criminalised and subject to censorship and punishment. More recently, the British anarcho-pacifist Alex Comfort gained notoriety during the sexual revolution for writing the bestseller sex manual The Joy of Sex. The issue of free love has a dedicated treatment in the work of French anarcho-hedonist philosopher Michel Onfray in such works as Théorie du corps amoureux. Pour une érotique solaire (2000) and L'invention du plaisir. Fragments cyréaniques (2002). === Libertarian education and freethought === For English anarchist William Godwin, education was "the main means by which change would be achieved". Godwin saw that the main goal of education should be the promotion of happiness. For Godwin, education had to have a "respect for the child's autonomy which precluded any form of coercion", a "pedagogy that respected this and sought to build on the child's own motivation and initiatives" and a "concern about the child's capacity to resist an ideology transmitted through the school". In his Political Justice, he criticises state sponsored schooling "on account of its obvious alliance with national government". Early American anarchist Josiah Warren advanced alternative education experiences in the libertarian communities he established. Max Stirner wrote in 1842 a long essay on education called The False Principle of our Education in which Stirner names his educational principle "personalist", explaining that self-understanding consists in hourly self-creation. Education for him is to create "free men, sovereign characters", by which he means "eternal characters [...] who are therefore eternal because they form themselves each moment".In the United States, freethought was a basically anti-Christian, anti-clerical movement, whose purpose was to make the individual politically and spiritually free to decide for himself on religious matters. A number of contributors to Liberty (anarchist publication) were prominent figures in both freethought and anarchism. The individualist anarchist George MacDonald was a co-editor of Freethought and, for a time, The Truth Seeker. E.C. Walker was co-editor of Lucifer, the Light-Bearer and many anarchists were "ardent freethinkers; reprints from freethought papers such as Lucifer, the Light-Bearer, Freethought and The Truth Seeker appeared in Liberty... The church was viewed as a common ally of the state and as a repressive force in and of itself".In 1901, Catalan anarchist and free thinker Francesc Ferrer i Guàrdia established "modern" or progressive schools in Barcelona in defiance of an educational system controlled by the Catholic Church. The schools' stated goal was to "educate the working class in a rational, secular and non-coercive setting". Fiercely anti-clerical, Ferrer believed in "freedom in education", education free from the authority of church and state. Murray Bookchin wrote: "This period [1890s] was the heyday of libertarian schools and pedagogical projects in all areas of the country where Anarchists exercised some degree of influence. Perhaps the best-known effort in this field was Francisco Ferrer's Modern School (Escuela Moderna), a project which exercised a considerable influence on Catalan education and on experimental techniques of teaching generally". La Escuela Moderna and Ferrer's ideas generally formed the inspiration for a series of Modern Schools in the United States, Cuba, South America and London. The first of these was started in New York City in 1911. It also inspired the Italian newspaper Università popolare, founded in 1901. Russian christian anarchist Leo Tolstoy established a school for peasant children on his estate. Tolstoy's educational experiments were short-lived due to harassment by the Tsarist secret police. Tolstoy established a conceptual difference between education and culture. He thought that "[e]ducation is the tendency of one man to make another just like himself [...] Education is culture under restraint, culture is free. [Education is] when the teaching is forced upon the pupil, and when then instruction is exclusive, that is when only those subjects are taught which the educator regards as necessary". For him, "without compulsion, education was transformed into culture".A more recent libertarian tradition on education is that of unschooling and the free school in which child-led activity replaces pedagogic approaches. Experiments in Germany led to A. S. Neill founding what became Summerhill School in 1921. Summerhill is often cited as an example of anarchism in practice. However, although Summerhill and other free schools are radically libertarian, they differ in principle from those of Ferrer by not advocating an overtly political class struggle-approach. In addition to organising schools according to libertarian principles, anarchists have also questioned the concept of schooling per se. The term deschooling was popularised by Ivan Illich, who argued that the school as an institution is dysfunctional for self-determined learning and serves the creation of a consumer society instead. == List of anarchist societies == Kibbutz (1909–present) Federation of Neighborhood Councils-El Alto (Fejuve; 1979–present) Popular Indigenous Council of Oaxaca "Ricardo Flores Magón" (CIPO-RFM; 1980s–present) Landless Workers' Movement (MST; 1982–present) Rebel Zapatista Autonomous Municipalities (MANEZ; 1994–present) Barbacha (2001–present) Villa de Zaachila (2006–present) Cheran (2011–present) Democratic Federation of Northern Syria (Rojava; 2013–present) == Criticisms == Criticisms of anarchism include moral criticisms and pragmatic criticisms.

### Instruction: retrieve labels for this: Albedo () (Latin: albedo, meaning "whiteness") is the measure of the diffuse reflection of solar radiation out of the total solar radiation received by an astronomical body (e.g. a planet like Earth). It is dimensionless and measured on a scale from 0 (corresponding to a black body that absorbs all incident radiation) to 1 (corresponding to a body that reflects all incident radiation). Surface albedo is defined as the ratio of irradiance reflected to the irradiance received by a surface. The proportion reflected is not only determined by properties of the surface itself, but also by the spectral and angular distribution of solar radiation reaching the Earth's surface. These factors vary with atmospheric composition, geographic location and time (see position of the Sun). While bi-hemispherical reflectance is calculated for a single angle of incidence (i.e., for a given position of the Sun), albedo is the directional integration of reflectance over all solar angles in a given period. The temporal resolution may range from seconds (as obtained from flux measurements) to daily, monthly, or annual averages. Unless given for a specific wavelength (spectral albedo), albedo refers to the entire spectrum of solar radiation. Due to measurement constraints, it is often given for the spectrum in which most solar energy reaches the surface (between 0.3 and 3 μm). This spectrum includes visible light (0.39–0.7 μm), which explains why surfaces with a low albedo appear dark (e.g., trees absorb most radiation), whereas surfaces with a high albedo appear bright (e.g., snow reflects most radiation). Albedo is an important concept in climatology, astronomy, and environmental management (e.g., as part of the Leadership in Energy and Environmental Design (LEED) program for sustainable rating of buildings). The average albedo of the Earth from the upper atmosphere, its planetary albedo, is 30–35% because of cloud cover, but widely varies locally across the surface because of different geological and environmental features.The term albedo was introduced into optics by Johann Heinrich Lambert in his 1760 work Photometria. == Terrestrial albedo == Any albedo in visible light falls within a range of about 0.9 for fresh snow to about 0.04 for charcoal, one of the darkest substances. Deeply shadowed cavities can achieve an effective albedo approaching the zero of a black body. When seen from a distance, the ocean surface has a low albedo, as do most forests, whereas desert areas have some of the highest albedos among landforms. Most land areas are in an albedo range of 0.1 to 0.4. The average albedo of Earth is about 0.3. This is far higher than for the ocean primarily because of the contribution of clouds. Earth's surface albedo is regularly estimated via Earth observation satellite sensors such as NASA's MODIS instruments on board the Terra and Aqua satellites, and the CERES instrument on the Suomi NPP and JPSS. As the amount of reflected radiation is only measured for a single direction by satellite, not all directions, a mathematical model is used to translate a sample set of satellite reflectance measurements into estimates of directional-hemispherical reflectance and bi-hemispherical reflectance (e.g.,). These calculations are based on the bidirectional reflectance distribution function (BRDF), which describes how the reflectance of a given surface depends on the view angle of the observer and the solar angle. BDRF can facilitate translations of observations of reflectance into albedo. Earth's average surface temperature due to its albedo and the greenhouse effect is currently about 15 °C. If Earth were frozen entirely (and hence be more reflective), the average temperature of the planet would drop below −40 °C. If only the continental land masses became covered by glaciers, the mean temperature of the planet would drop to about 0 °C. In contrast, if the entire Earth was covered by water — a so-called aquaplanet — the average temperature on the planet would rise to almost 27 °C. === White-sky and black-sky albedo === For land surfaces, it has been shown that the albedo at a particular solar zenith angle θi can be approximated by the proportionate sum of two terms: the directional-hemispherical reflectance at that solar zenith angle, α ¯ ( θ i ) {\displaystyle {{\bar {\alpha }}(\theta _{i})}} , and the bi-hemispherical reflectance, α ¯ ¯ {\displaystyle {\bar {\bar {\alpha }}}} , with D − 1 {\displaystyle {D-1}} being the proportion of direct radiation from a given solar angle, and D {\displaystyle {D}} being the proportion of diffuse illumination. Hence, the actual albedo α {\displaystyle {\alpha }} (also called blue-sky albedo) can then be given as: α = ( 1 − D ) α ¯ ( θ i ) + D α ¯ ¯ . {\displaystyle {\alpha }=(1-D){\bar {\alpha }}(\theta _{i})+D{\bar {\bar {\alpha }}}.} Directional-hemispherical reflectance is sometimes referred to as black-sky albedo and bi-hemispherical reflectance as white-sky albedo. These terms are important because they allow the albedo to be calculated for any given illumination conditions from a knowledge of the intrinsic properties of the surface. == Astronomical albedo == The albedos of planets, satellites and minor planets such as asteroids can be used to infer much about their properties. The study of albedos, their dependence on wavelength, lighting angle ("phase angle"), and variation in time comprises a major part of the astronomical field of photometry. For small and far objects that cannot be resolved by telescopes, much of what we know comes from the study of their albedos. For example, the absolute albedo can indicate the surface ice content of outer Solar System objects, the variation of albedo with phase angle gives information about regolith properties, whereas unusually high radar albedo is indicative of high metal content in asteroids. Enceladus, a moon of Saturn, has one of the highest known albedos of any body in the Solar System, with 99% of EM radiation reflected. Another notable high-albedo body is Eris, with an albedo of 0.96. Many small objects in the outer Solar System and asteroid belt have low albedos down to about 0.05. A typical comet nucleus has an albedo of 0.04. Such a dark surface is thought to be indicative of a primitive and heavily space weathered surface containing some organic compounds. The overall albedo of the Moon is measured to be around 0.136, but it is strongly directional and non-Lambertian, displaying also a strong opposition effect. Although such reflectance properties are different from those of any terrestrial terrains, they are typical of the regolith surfaces of airless Solar System bodies. Two common albedos that are used in astronomy are the (V-band) geometric albedo (measuring brightness when illumination comes from directly behind the observer) and the Bond albedo (measuring total proportion of electromagnetic energy reflected). Their values can differ significantly, which is a common source of confusion. In detailed studies, the directional reflectance properties of astronomical bodies are often expressed in terms of the five Hapke parameters which semi-empirically describe the variation of albedo with phase angle, including a characterization of the opposition effect of regolith surfaces. The correlation between astronomical (geometric) albedo, absolute magnitude and diameter is: A = ( 1329 × 10 − H / 5 D ) 2 {\displaystyle A=\left({\frac {1329\times 10^{-H/5}}{D}}\right)^{2}} , where A {\displaystyle A} is the astronomical albedo, D {\displaystyle D} is the diameter in kilometers, and H {\displaystyle H} is the absolute magnitude. == Examples of terrestrial albedo effects == === Illumination === Albedo is not directly dependent on illumination because changing the amount of incoming light proportionally changes the amount of reflected light, except in circumstances where a change in illumination induces a change in the Earth's surface at that location (e.g. through albedo-temperature feedback). That said, albedo and illumination both vary by latitude. Albedo is highest near the poles and lowest in the subtropics, with a local maximum in the tropics. === Insolation effects === The intensity of albedo temperature effects depend on the amount of albedo and the level of local insolation (solar irradiance); high albedo areas in the arctic and antarctic regions are cold due to low insolation, where areas such as the Sahara Desert, which also have a relatively high albedo, will be hotter due to high insolation. Tropical and sub-tropical rainforest areas have low albedo, and are much hotter than their temperate forest counterparts, which have lower insolation. Because insolation plays such a big role in the heating and cooling effects of albedo, high insolation areas like the tropics will tend to show a more pronounced fluctuation in local temperature when local albedo changes.Arctic regions notably release more heat back into space than what they absorb, effectively cooling the Earth. This has been a concern since arctic ice and snow has been melting at higher rates due to higher temperatures, creating regions in the arctic that are notably darker (being water or ground which is darker color) and reflects less heat back into space. This feedback loop results in a reduced albedo effect. === Climate and weather === Albedo affects climate by determining how much radiation a planet absorbs. The uneven heating of Earth from albedo variations between land, ice, or ocean surfaces can drive weather. === Albedo–temperature feedback === When an area's albedo changes due to snowfall, a snow–temperature feedback results. A layer of snowfall increases local albedo, reflecting away sunlight, leading to local cooling. In principle, if no outside temperature change affects this area (e.g., a warm air mass), the raised albedo and lower temperature would maintain the current snow and invite further snowfall, deepening the snow–temperature feedback. However, because local weather is dynamic due to the change of seasons, eventually warm air masses and a more direct angle of sunlight (higher insolation) cause melting. When the melted area reveals surfaces with lower albedo, such as grass or soil, the effect is reversed: the darkening surface lowers albedo, increasing local temperatures, which induces more melting and thus reducing the albedo further, resulting in still more heating. === Snow === Snow albedo is highly variable, ranging from as high as 0.9 for freshly fallen snow, to about 0.4 for melting snow, and as low as 0.2 for dirty snow. Over Antarctica snow albedo averages a little more than 0.8. If a marginally snow-covered area warms, snow tends to melt, lowering the albedo, and hence leading to more snowmelt because more radiation is being absorbed by the snowpack (the ice–albedo positive feedback). Just as fresh snow has a higher albedo than does dirty snow, the albedo of snow-covered sea ice is far higher than that of sea water. Sea water absorbs more solar radiation than would the same surface covered with reflective snow. When sea ice melts, either due to a rise in sea temperature or in response to increased solar radiation from above, the snow-covered surface is reduced, and more surface of sea water is exposed, so the rate of energy absorption increases. The extra absorbed energy heats the sea water, which in turn increases the rate at which sea ice melts. As with the preceding example of snowmelt, the process of melting of sea ice is thus another example of a positive feedback. Both positive feedback loops have long been recognized as important to the modern theory of Global warming.Cryoconite, powdery windblown dust containing soot, sometimes reduces albedo on glaciers and ice sheets.The dynamical nature of albedo in response to positive feedback, together with the effects of small errors in the measurement of albedo, can lead to large errors in energy estimates. Because of this, in order to reduce the error of energy estimates, it is important to measure the albedo of snow-covered areas through remote sensing techniques rather than applying a single value for albedo over broad regions. === Small-scale effects === Albedo works on a smaller scale, too. In sunlight, dark clothes absorb more heat and light-coloured clothes reflect it better, thus allowing some control over body temperature by exploiting the albedo effect of the colour of external clothing. === Solar photovoltaic effects === Albedo can affect the electrical energy output of solar photovoltaic devices. For example, the effects of a spectrally responsive albedo are illustrated by the differences between the spectrally weighted albedo of solar photovoltaic technology based on hydrogenated amorphous silicon (a-Si:H) and crystalline silicon (c-Si)-based compared to traditional spectral-integrated albedo predictions. Research showed impacts of over 10%. More recently, the analysis was extended to the effects of spectral bias due to the specular reflectivity of 22 commonly occurring surface materials (both human-made and natural) and analyzes the albedo effects on the performance of seven photovoltaic materials covering three common photovoltaic system topologies: industrial (solar farms), commercial flat rooftops and residential pitched-roof applications. === Trees === Because forests generally have a low albedo, (the majority of the ultraviolet and visible spectrum is absorbed through photosynthesis), some scientists have suggested that greater heat absorption by trees could offset some of the carbon benefits of afforestation (or offset the negative climate impacts of deforestation). In the case of evergreen forests with seasonal snow cover albedo reduction may be great enough for deforestation to cause a net cooling effect. Trees also impact climate in extremely complicated ways through evapotranspiration. The water vapor causes cooling on the land surface, causes heating where it condenses, acts a strong greenhouse gas, and can increase albedo when it condenses into clouds Scientists generally treat evapotranspiration as a net cooling impact, and the net climate impact of albedo and evapotranspiration changes from deforestation depends greatly on local climate In seasonally snow-covered zones, winter albedos of treeless areas are 10% to 50% higher than nearby forested areas because snow does not cover the trees as readily. Deciduous trees have an albedo value of about 0.15 to 0.18 whereas coniferous trees have a value of about 0.09 to 0.15.Studies by the Hadley Centre have investigated the relative (generally warming) effect of albedo change and (cooling) effect of carbon sequestration on planting forests. They found that new forests in tropical and midlatitude areas tended to cool; new forests in high latitudes (e.g., Siberia) were neutral or perhaps warming. === Water === Water reflects light very differently from typical terrestrial materials. The reflectivity of a water surface is calculated using the Fresnel equations (see graph). At the scale of the wavelength of light even wavy water is always smooth so the light is reflected in a locally specular manner (not diffusely). The glint of light off water is a commonplace effect of this. At small angles of incident light, waviness results in reduced reflectivity because of the steepness of the reflectivity-vs.-incident-angle curve and a locally increased average incident angle.Although the reflectivity of water is very low at low and medium angles of incident light, it becomes very high at high angles of incident light such as those that occur on the illuminated side of Earth near the terminator (early morning, late afternoon, and near the poles). However, as mentioned above, waviness causes an appreciable reduction. Because light specularly reflected from water does not usually reach the viewer, water is usually considered to have a very low albedo in spite of its high reflectivity at high angles of incident light. Note that white caps on waves look white (and have high albedo) because the water is foamed up, so there are many superimposed bubble surfaces which reflect, adding up their reflectivities. Fresh 'black' ice exhibits Fresnel reflection. Snow on top of this sea ice increases the albedo to 0.9. === Clouds === Cloud albedo has substantial influence over atmospheric temperatures. Different types of clouds exhibit different reflectivity, theoretically ranging in albedo from a minimum of near 0 to a maximum approaching 0.8. "On any given day, about half of Earth is covered by clouds, which reflect more sunlight than land and water. Clouds keep Earth cool by reflecting sunlight, but they can also serve as blankets to trap warmth."Albedo and climate in some areas are affected by artificial clouds, such as those created by the contrails of heavy commercial airliner traffic. A study following the burning of the Kuwaiti oil fields during Iraqi occupation showed that temperatures under the burning oil fires were as much as 10 °C colder than temperatures several miles away under clear skies. === Aerosol effects === Aerosols (very fine particles/droplets in the atmosphere) have both direct and indirect effects on Earth's radiative balance. The direct (albedo) effect is generally to cool the planet; the indirect effect (the particles act as cloud condensation nuclei and thereby change cloud properties) is less certain. As per the effects are: Aerosol direct effect. Aerosols directly scatter and absorb radiation. The scattering of radiation causes atmospheric cooling, whereas absorption can cause atmospheric warming. Aerosol indirect effect. Aerosols modify the properties of clouds through a subset of the aerosol population called cloud condensation nuclei. Increased nuclei concentrations lead to increased cloud droplet number concentrations, which in turn leads to increased cloud albedo, increased light scattering and radiative cooling (first indirect effect), but also leads to reduced precipitation efficiency and increased lifetime of the cloud (second indirect effect). === Black carbon === Another albedo-related effect on the climate is from black carbon particles. The size of this effect is difficult to quantify: the Intergovernmental Panel on Climate Change estimates that the global mean radiative forcing for black carbon aerosols from fossil fuels is +0.2 W m−2, with a range +0.1 to +0.4 W m−2. Black carbon is a bigger cause of the melting of the polar ice cap in the Arctic than carbon dioxide due to its effect on the albedo. === Human activities === Human activities (e.g., deforestation, farming, and urbanization) change the albedo of various areas around the globe. However, quantification of this effect on the global scale is difficult. == Other types of albedo == Single-scattering albedo is used to define scattering of electromagnetic waves on small particles. It depends on properties of the material (refractive index); the size of the particle or particles; and the wavelength of the incoming radiation. == See also == == References == == External links == Official Website of Albedo Project Global Albedo Project (Center for Clouds, Chemistry, and Climate) Albedo – Encyclopedia of Earth NASA MODIS BRDF/albedo product site Surface albedo derived from Meteosat observations A discussion of Lunar albedos reflectivity of metals (chart) ### Answer: <Climate forcing>, <Climatology>, <Electromagnetic radiation>, <Radiation>, <Radiometry>, <Scattering, absorption and radiative transfer (optics)>

### Instruction: retrieve labels for this: In Greek mythology, Achilles or Achilleus ( ə-KIL-eez; Greek: Ἀχιλλεύς, Achilleus [a.kʰil.le͜ús]) was a Greek hero of the Trojan War and the central character and greatest warrior of Homer's Iliad. His mother was the immortal Nereid Thetis, and his father, the mortal Peleus, was the king of the Myrmidons. Achilles' most notable feat during the Trojan War was the slaying of the Trojan hero Hector outside the gates of Troy. Although the death of Achilles is not presented in the Iliad, other sources concur that he was killed near the end of the Trojan War by Paris, who shot him in the heel with an arrow. Later legends (beginning with a poem by Statius in the 1st century AD) state that Achilles was invulnerable in all of his body except for his heel because, when his mother Thetis dipped him in the river Styx as an infant, she held him by one of his heels. Alluding to these legends, the term "Achilles heel" has come to mean a point of weakness, especially in someone or something with an otherwise strong constitution. == Etymology == Linear B tablets attest to the personal name Achilleus in the forms a-ki-re-u and a-ki-re-we, the latter being the dative of the former. The name grew more popular, even becoming common soon after the seventh century BC and was also turned into the female form Ἀχιλλεία (Achilleía), attested in Attica in the fourth century BC (IG II² 1617) and, in the form Achillia, on a stele in Halicarnassus as the name of a female gladiator fighting an "Amazon". Achilles' name can be analyzed as a combination of ἄχος (áchos) "distress, pain, sorrow, grief" and λαός (laós) "people, soldiers, nation", resulting in a proto-form *Akhí-lāu̯os "he who has the people distressed" or "he whose people have distress". The grief or distress of the people is a theme raised numerous times in the Iliad (and frequently by Achilles himself). Achilles' role as the hero of grief or distress forms an ironic juxtaposition with the conventional view of him as the hero of κλέος kléos ("glory", usually in war). Furthermore, laós has been construed by Gregory Nagy, following Leonard Palmer, to mean "a corps of soldiers", a muster. With this derivation, the name obtains a double meaning in the poem: when the hero is functioning rightly, his men bring distress to the enemy, but when wrongly, his men get the grief of war. The poem is in part about the misdirection of anger on the part of leadership. Another etymology relates the name to a Proto-Indo-European compound *h₂eḱ-pṓds "sharp foot" which first gave an Illyrian *āk̂pediós, evolving through time into *ākhpdeós and then *akhiddeús. The shift from -dd- to -ll- is then ascribed to the passing of the name into Greek via a Pre-Greek source. The first root part *h₂eḱ- "sharp, pointed" also gave Greek ἀκή (akḗ "point, silence, healing"), ἀκμή (akmḗ "point, edge, zenith") and ὀξύς (oxús "sharp, pointed, keen, quick, clever"), whereas ἄχος stems from the root *h₂egʰ- "to be upset, afraid". The whole expression would be comparable to the Latin acupedius "swift of foot". Compare also the Latin word family of aciēs "sharp edge or point, battle line, battle, engagement", acus "needle, pin, bodkin", and acuō "to make pointed, sharpen, whet; to exercise; to arouse" (whence acute). Some topical epitheta of Achilles in the Iliad point to this "swift-footedness", namely ποδάρκης δῖος Ἀχιλλεὺς (podárkēs dĩos Achilleús "swift-footed divine Achilles") or, even more frequently, πόδας ὠκὺς Ἀχιλλεύς (pódas ōkús Achilleús "quick-footed Achilles").Some researchers deem the name a loan word, possibly from a Pre-Greek language. Achilles' descent from the Nereid Thetis and a similarity of his name with those of river deities such as Acheron and Achelous have led to speculations about him being an old water divinity (see below Worship). Robert S. P. Beekes has suggested a Pre-Greek origin of the name, based among other things on the coexistence of -λλ- and -λ- in epic language, which may account for a palatalized phoneme /ly/ in the original language. == Birth and early years == Achilles was the son of the Nereid Thetis and of Peleus, the king of the Myrmidons. Zeus and Poseidon had been rivals for the hand of Thetis until Prometheus, the fore-thinker, warned Zeus of a prophecy (originally uttered by Themis, goddess of divine law) that Thetis would bear a son greater than his father. For this reason, the two gods withdrew their pursuit, and had her wed Peleus. There is a tale which offers an alternative version of these events: In the Argonautica (4.760) Zeus' sister and wife Hera alludes to Thetis' chaste resistance to the advances of Zeus, pointing out that Thetis was so loyal to Hera's marriage bond that she coolly rejected the father of gods. Thetis, although a daughter of the sea-god Nereus, was also brought up by Hera, further explaining her resistance to the advances of Zeus. Zeus was furious and decreed that she would never marry an immortal. According to the Achilleid, written by Statius in the 1st century AD, and to non-surviving previous sources, when Achilles was born Thetis tried to make him immortal, by dipping him in the river Styx. However, he was left vulnerable at the part of the body by which she held him, his left heel (see Achilles' heel, Achilles' tendon). It is not clear if this version of events was known earlier. In another version of this story, Thetis anointed the boy in ambrosia and put him on top of a fire, to burn away the mortal parts of his body. She was interrupted by Peleus and abandoned both father and son in a rage.However, none of the sources before Statius makes any reference to this general invulnerability. To the contrary, in the Iliad Homer mentions Achilles being wounded: in Book 21 the Paeonian hero Asteropaeus, son of Pelagon, challenged Achilles by the river Scamander. He cast two spears at once, one grazed Achilles' elbow, "drawing a spurt of blood". Also, in the fragmentary poems of the Epic Cycle in which we can find description of the hero's death (i.e. the Cypria, the Little Iliad by Lesches of Pyrrha, the Aithiopis and Iliou persis by Arctinus of Miletus), there is no trace of any reference to his general invulnerability or his famous weakness at the heel; in the later vase paintings presenting Achilles' death, the arrow (or in many cases, arrows) hit his body. Peleus entrusted Achilles to Chiron the Centaur, on Mount Pelion, to be reared. Thetis foretold that her son's fate was either to gain glory and die young, or to live a long but uneventful life in obscurity. Achilles chose the former, and decided to take part in the Trojan war. According to Homer, Achilles grew up in Phthia together with his companion Patroclus.According to Photius, the sixth book of the New History by Ptolemy Hephaestion reported that Thetis burned in a secret place the children she had by Peleus; but when she had Achilles, Peleus noticed, tore him from the flames with only a burnt foot, and confided him to the centaur Chiron. Later Chiron exhumed the body of the Damysus, who was the fastest of all the giants, removed the ankle, and incorporated it into Achilles' burnt foot. === Hidden on Skyros === Some post-Homeric sources claim that in order to keep Achilles safe from the war, Thetis (or, in some versions, Peleus) hid the young man at the court of Lycomedes, king of Skyros. There, Achilles is disguised as a girl and lives among Lycomedes' daughters, perhaps under the name "Pyrrha" (the red-haired girl). With Lycomedes' daughter Deidamia, whom in the account of Statius he rapes, Achilles there fathers a son, Neoptolemus (also called Pyrrhus, after his father's possible alias). According to this story, Odysseus learns from the prophet Calchas that the Achaeans would be unable to capture Troy without Achilles' aid. Odysseus goes to Skyros in the guise of a peddler selling women's clothes and jewelry and places a shield and spear among his goods. When Achilles instantly takes up the spear, Odysseus sees through his disguise and convinces him to join the Greek campaign. In another version of the story, Odysseus arranges for a trumpet alarm to be sounded while he was with Lycomedes' women; while the women flee in panic, Achilles prepares to defend the court, thus giving his identity away. == Achilles in the Trojan War == According to the Iliad, Achilles arrived at Troy with 50 ships, each carrying 50 Myrmidons. He appointed five leaders (each leader commanding 500 Myrmidons): Menesthius, Eudorus, Peisander, Phoenix and Alcimedon. === Telephus === When the Greeks left for the Trojan War, they accidentally stopped in Mysia, ruled by King Telephus. In the resulting battle, Achilles gave Telephus a wound that would not heal; Telephus consulted an oracle, who stated that "he that wounded shall heal". Guided by the oracle, he arrived at Argos, where Achilles healed him in order that he might become their guide for the voyage to Troy.According to other reports in Euripides' lost play about Telephus, he went to Aulis pretending to be a beggar and asked Achilles to heal his wound. Achilles refused, claiming to have no medical knowledge. Alternatively, Telephus held Orestes for ransom, the ransom being Achilles' aid in healing the wound. Odysseus reasoned that the spear had inflicted the wound; therefore, the spear must be able to heal it. Pieces of the spear were scraped off onto the wound and Telephus was healed. === Troilus === According to the Cypria (the part of the Epic Cycle that tells the events of the Trojan War before Achilles' wrath), when the Achaeans desired to return home, they were restrained by Achilles, who afterwards attacked the cattle of Aeneas, sacked neighbouring cities (like Pedasus and Lyrnessus, where the Greeks capture the queen Briseis) and killed Tenes, a son of Apollo, as well as Priam's son Troilus in the sanctuary of Apollo Thymbraios. However, the romance between Troilus and Chryseis described in Geoffrey Chaucer's Troilus and Criseyde and in William Shakespeare's Troilus and Cressida is a medieval invention.In Dares Phrygius' Account of the Destruction of Troy, the Latin summary through which the story of Achilles was transmitted to medieval Europe, as well as in older accounts, Troilus was a young Trojan prince, the youngest of King Priam's and Hecuba's five legitimate sons (or according other sources, another son of Apollo). Despite his youth, he was one of the main Trojan war leaders, a "horse fighter" or "chariot fighter" according to Homer. Prophecies linked Troilus' fate to that of Troy and so he was ambushed in an attempt to capture him. Yet Achilles, struck by the beauty of both Troilus and his sister Polyxena, and overcome with lust, directed his sexual attentions on the youth – who, refusing to yield, instead found himself decapitated upon an altar-omphalos of Apollo Thymbraios. Later versions of the story suggested Troilus was accidentally killed by Achilles in an over-ardent lovers' embrace. In this version of the myth, Achilles' death therefore came in retribution for this sacrilege. Ancient writers treated Troilus as the epitome of a dead child mourned by his parents. Had Troilus lived to adulthood, the First Vatican Mythographer claimed, Troy would have been invincible. === Achilles in the Iliad === Homer's Iliad is the most famous narrative of Achilles' deeds in the Trojan War. Achilles' wrath (μῆνις Ἀχιλλέως, mênis Achilléōs) is the central theme of the poem. The first two lines of the Iliad read: The Homeric epic only covers a few weeks of the decade-long war, and does not narrate Achilles' death. It begins with Achilles' withdrawal from battle after being dishonoured by Agamemnon, the commander of the Achaean forces. Agamemnon has taken a woman named Chryseis as his slave. Her father Chryses, a priest of Apollo, begs Agamemnon to return her to him. Agamemnon refuses, and Apollo sends a plague amongst the Greeks. The prophet Calchas correctly determines the source of the troubles but will not speak unless Achilles vows to protect him. Achilles does so, and Calchas declares that Chryseis must be returned to her father. Agamemnon consents, but then commands that Achilles' battle prize Briseis, the daughter of Briseus, be brought to him to replace Chryseis. Angry at the dishonour of having his plunder and glory taken away (and, as he says later, because he loves Briseis), with the urging of his mother Thetis, Achilles refuses to fight or lead his troops alongside the other Greek forces. At the same time, burning with rage over Agamemnon's theft, Achilles prays to Thetis to convince Zeus to help the Trojans gain ground in the war, so that he may regain his honour. As the battle turns against the Greeks, thanks to the influence of Zeus, Nestor declares that the Trojans are winning because Agamemnon has angered Achilles, and urges the king to appease the warrior. Agamemnon agrees and sends Odysseus and two other chieftains, Ajax and Phoenix, to Achilles with the offer of the return of Briseis and other gifts. Achilles rejects all Agamemnon offers him and simply urges the Greeks to sail home as he was planning to do. The Trojans, led by Hector, subsequently push the Greek army back toward the beaches and assault the Greek ships. With the Greek forces on the verge of absolute destruction, Patroclus leads the Myrmidons into battle, wearing Achilles' armour, though Achilles remains at his camp. Patroclus succeeds in pushing the Trojans back from the beaches, but is killed by Hector before he can lead a proper assault on the city of Troy. After receiving the news of the death of Patroclus from Antilochus, the son of Nestor, Achilles grieves over his beloved companion's death. His mother Thetis comes to comfort the distraught Achilles. She persuades Hephaestus to make new armour for him, in place of the armour that Patroclus had been wearing, which was taken by Hector. The new armour includes the Shield of Achilles, described in great detail in the poem. Enraged over the death of Patroclus, Achilles ends his refusal to fight and takes the field, killing many men in his rage but always seeking out Hector. Achilles even engages in battle with the river god Scamander, who has become angry that Achilles is choking his waters with all the men he has killed. The god tries to drown Achilles but is stopped by Hera and Hephaestus. Zeus himself takes note of Achilles' rage and sends the gods to restrain him so that he will not go on to sack Troy itself before the time allotted for its destruction, seeming to show that the unhindered rage of Achilles can defy fate itself. Finally, Achilles finds his prey. Achilles chases Hector around the wall of Troy three times before Athena, in the form of Hector's favorite and dearest brother, Deiphobus, persuades Hector to stop running and fight Achilles face to face. After Hector realizes the trick, he knows the battle is inevitable. Wanting to go down fighting, he charges at Achilles with his only weapon, his sword, but misses. Accepting his fate, Hector begs Achilles, not to spare his life, but to treat his body with respect after killing him. Achilles tells Hector it is hopeless to expect that of him, declaring that "my rage, my fury would drive me now to hack your flesh away and eat you raw – such agonies you have caused me". Achilles then kills Hector and drags his corpse by its heels behind his chariot. After having a dream where Patroclus begs Achilles to hold his funeral, Achilles hosts a series of funeral games in his honour.With the assistance of the god Hermes, Hector's father, Priam, goes to Achilles' tent to plead with Achilles for the return of Hector's body so that he can be buried. Achilles relents and promises a truce for the duration of the funeral. The poem ends with a description of Hector's funeral, with the doom of Troy and Achilles himself still to come. === Later epic accounts: fighting Penthesilea and Memnon === The Aethiopis (7th century BC) and a work named Posthomerica, composed by Quintus of Smyrna in the fourth century AD, relate further events from the Trojan War. When Penthesilea, queen of the Amazons and daughter of Ares, arrives in Troy, Priam hopes that she will defeat Achilles. After his temporary truce with Priam, Achilles fights and kills the warrior queen, only to grieve over her death later. At first, he was so distracted by her beauty, he did not fight as intensely as usual. Once he realized that his distraction was endangering his life, he refocused and killed her. Following the death of Patroclus, Nestor's son Antilochus becomes Achilles' closest companion. When Memnon, son of the Dawn Goddess Eos and king of Ethiopia, slays Antilochus, Achilles once more obtains revenge on the battlefield, killing Memnon. Consequently, Eos will not let the sun rise, until Zeus persuades her. The fight between Achilles and Memnon over Antilochus echoes that of Achilles and Hector over Patroclus, except that Memnon (unlike Hector) was also the son of a goddess. Many Homeric scholars argued that episode inspired many details in the Iliad's description of the death of Patroclus and Achilles' reaction to it. The episode then formed the basis of the cyclic epic Aethiopis, which was composed after the Iliad, possibly in the 7th century BC. The Aethiopis is now lost, except for scattered fragments quoted by later authors. === Achilles and Patroclus === The exact nature of Achilles' relationship with Patroclus has been a subject of dispute in both the classical period and modern times. In the Iliad, it appears to be the model of a deep and loyal friendship. Homer does not suggest that Achilles and his close friend Patroclus were lovers. Despite there being no direct evidence in the text of the Iliad that Achilles and Patroclus were lovers, this theory was expressed by some later authors. Commentators from classical antiquity to the present have often interpreted the relationship through the lens of their own cultures. In 5th-century BC Athens, the intense bond was often viewed in light of the Greek custom of paiderasteia. In Plato's Symposium, the participants in a dialogue about love assume that Achilles and Patroclus were a couple; Phaedrus argues that Achilles was the younger and more beautiful one so he was the beloved and Patroclus was the lover. But ancient Greek had no words to distinguish heterosexual and homosexual, and it was assumed that a man could both desire handsome young men and have sex with women. === Achilles' death === The death of Achilles, as predicted by Hector with his dying breath, was brought about by Paris with an arrow (to the heel according to Statius). In some versions, the god Apollo guided Paris' arrow. Some retellings also state that Achilles was scaling the gates of Troy and was hit with a poisoned arrow. All of these versions deny Paris any sort of valour, owing to the common conception that Paris was a coward and not the man his brother Hector was, and Achilles remained undefeated on the battlefield. His bones were mingled with those of Patroclus, and funeral games were held. He was represented in the Aethiopis as living after his death in the island of Leuke at the mouth of the river Danube. Another version of Achilles' death is that he fell deeply in love with one of the Trojan princesses, Polyxena. Achilles asks Priam for Polyxena's hand in marriage. Priam is willing because it would mean the end of the war and an alliance with the world's greatest warrior. But while Priam is overseeing the private marriage of Polyxena and Achilles, Paris, who would have to give up Helen if Achilles married his sister, hides in the bushes and shoots Achilles with a divine arrow, killing him. In the Odyssey, Agamemnon informs Achilles of his pompous burial and the erection of his mound at the Hellespont while they are receiving the dead suitors in Hades. He claims they built a massive burial mound on the beach of Ilion that could be seen by anyone approaching from the Ocean. Achilles was cremated and his ashes buried in the same urn as those of Patroclus. Paris was later killed by Philoctetes using the enormous bow of Heracles. In Book 11 of Homer's Odyssey, Odysseus sails to the underworld and converses with the shades. One of these is Achilles, who when greeted as "blessed in life, blessed in death", responds that he would rather be a slave to the worst of masters than be king of all the dead. But Achilles then asks Odysseus of his son's exploits in the Trojan war, and when Odysseus tells of Neoptolemus' heroic actions, Achilles is filled with satisfaction. This leaves the reader with an ambiguous understanding of how Achilles felt about the heroic life. According to some accounts, he had married Medea in life, so that after both their deaths they were united in the Elysian Fields of Hades – as Hera promised Thetis in Apollonius' Argonautica (3rd century BC). === The fate of Achilles' armour === Achilles' armour was the object of a feud between Odysseus and Telamonian Ajax (Ajax the greater). They competed for it by giving speeches on why they were the bravest after Achilles to their Trojan prisoners, who after considering both men, decided Odysseus was more deserving of the armour. Furious, Ajax cursed Odysseus, which earned him the ire of Athena. Athena temporarily made Ajax so mad with grief and anguish that he began killing sheep, thinking them his comrades. After a while, when Athena lifted his madness and Ajax realized that he had actually been killing sheep, Ajax was left so ashamed that he committed suicide. Odysseus eventually gave the armour to Neoptolemus, the son of Achilles. A relic claimed to be Achilles' bronze-headed spear was for centuries preserved in the temple of Athena on the acropolis of Phaselis, Lycia, a port on the Pamphylian Gulf. The city was visited in 333 BC by Alexander the Great, who envisioned himself as the new Achilles and carried the Iliad with him, but his court biographers do not mention the spear. However, it was shown in the time of Pausanias in the 2nd century AD. === Achilles, Ajax and a game of petteia === Numerous paintings on pottery have suggested a tale not mentioned in the literary traditions. At some point in the war, Achilles and Ajax were playing a board game (petteia). They were absorbed in the game and oblivious to the surrounding battle. The Trojans attacked and reached the heroes, who were saved only by an intervention of Athena. == Worship and heroic cult == The tomb of Achilles, extant throughout antiquity in Troad, was venerated by Thessalians, but also by Persian expeditionary forces, as well as by Alexander the Great and the Roman emperor Caracalla. Achilles' cult was also to be found at other places, e. g. on the island of Astypalaea in the Sporades, in Sparta which had a sanctuary, in Elis and in Achilles' homeland Thessaly, as well as in the Magna Graecia cities of Tarentum, Locri and Croton, accounting for an almost Panhellenic cult to the hero. The spread and intensity of the hero's veneration among the Greeks that had settled on the northern coast of the Pontus Euxinus, today's Black Sea, appears to have been remarkable. An archaic cult is attested for the Milesian colony of Olbia as well as for an island in the middle of the Black Sea, today identified with Snake Island (Ukrainian Зміїний, Zmiinyi, near Kiliya, Ukraine). Early dedicatory inscriptions from the Greek colonies on the Black Sea (graffiti and inscribed clay disks, these possibly being votive offerings, from Olbia, the area of Berezan Island and the Tauric Chersonese) attest the existence of a heroic cult of Achilles from the sixth century BC onwards. The cult was still thriving in the third century AD, when dedicatory stelae from Olbia refer to an Achilles Pontárchēs (Ποντάρχης, roughly "lord of the Sea," or "of the Pontus Euxinus"), who was invoked as a protector of the city of Olbia, venerated on par with Olympian gods such as the local Apollo Prostates, Hermes Agoraeus, or Poseidon.Pliny the Elder (23–79 AD) in his Natural History mentions a "port of the Achæi" and an "island of Achilles", famous for the tomb of that "man" (portus Achaeorum, insula Achillis, tumulo eius viri clara), situated somewhat nearby Olbia and the Dnieper-Bug Estuary; furthermore, at 125 Roman miles from this island, he places a peninsula "which stretches forth in the shape of a sword" obliquely, called Dromos Achilleos (Ἀχιλλέως δρόμος, Achilléōs drómos "the Race-course of Achilles") and considered the place of the hero's exercise or of games instituted by him. This last feature of Pliny's account is considered to be the iconic spit, called today Tendra (or Kosa Tendra and Kosa Djarilgatch), situated between the mouth of the Dnieper and Karkinit Bay, but which is hardly 125 Roman miles (c. 185 km) away from the Dnieper-Bug estuary, as Pliny states. (To the "Race-course" he gives a length of 80 miles, c. 120 km, whereas the spit measures c. 70 km today.) In the following chapter of his book, Pliny refers to the same island as Achillea and introduces two further names for it: Leuce or Macaron (from Greek [νῆσος] μακαρῶν "island of the blest"). The "present day" measures, he gives at this point, seem to account for an identification of Achillea or Leuce with today's Snake Island. Pliny's contemporary Pomponius Mela (c. 43 AD) tells that Achilles was buried on an island named Achillea, situated between the Borysthenes and the Ister, adding to the geographical confusion. Ruins of a square temple, measuring 30 meters to a side, possibly that dedicated to Achilles, were discovered by Captain Kritzikly in 1823 on Snake Island. A second exploration in 1840 showed that the construction of a lighthouse had destroyed all traces of this temple. A fifth century BC black-glazed lekythos inscription, found on the island in 1840, reads: "Glaukos, son of Poseidon, dedicated me to Achilles, lord of Leuke." In another inscription from the fifth or fourth century BC, a statue is dedicated to Achilles, lord of Leuke, by a citizen of Olbia, while in a further dedication, the city of Olbia confirms its continuous maintenance of the island's cult, again suggesting its quality as a place of a supra-regional hero veneration.The heroic cult dedicated to Achilles on Leuce seems to go back to an account from the lost epic Aethiopis according to which, after his untimely death, Thetis had snatched her son from the funeral pyre and removed him to a mythical Λεύκη Νῆσος (Leúkē Nêsos "White Island"). Already in the fifth century BC, Pindar had mentioned a cult of Achilles on a "bright island" (φαεννά νᾶσος, phaenná nâsos) of the Black Sea, while in another of his works, Pindar would retell the story of the immortalized Achilles living on a geographically indefinite Island of the Blest together with other heroes such as his father Peleus and Cadmus. Well known is the connection of these mythological Fortunate Isles (μακαρῶν νῆσοι, makárôn nêsoi) or the Homeric Elysium with the stream Oceanus which according to Greek mythology surrounds the inhabited world, which should have accounted for the identification of the northern strands of the Euxine with it. Guy Hedreen has found further evidence for this connection of Achilles with the northern margin of the inhabited world in a poem by Alcaeus, speaking of "Achilles lord of Scythia" and the opposition of North and South, as evoked by Achilles' fight against the Aethiopian prince Memnon, who in his turn would be removed to his homeland by his mother Eos after his death. The Periplus of the Euxine Sea (c. 130 AD) gives the following details: It is said that the goddess Thetis raised this island from the sea, for her son Achilles, who dwells there. Here is his temple and his statue, an archaic work. This island is not inhabited, and goats graze on it, not many, which the people who happen to arrive here with their ships, sacrifice to Achilles. In this temple are also deposited a great many holy gifts, craters, rings and precious stones, offered to Achilles in gratitude. One can still read inscriptions in Greek and Latin, in which Achilles is praised and celebrated. Some of these are worded in Patroclus’ honour, because those who wish to be favored by Achilles, honour Patroclus at the same time. There are also in this island countless numbers of sea birds, which look after Achilles’ temple. Every morning they fly out to sea, wet their wings with water, and return quickly to the temple and sprinkle it. And after they finish the sprinkling, they clean the hearth of the temple with their wings. Other people say still more, that some of the men who reach this island, come here intentionally. They bring animals in their ships, destined to be sacrificed. Some of these animals they slaughter, others they set free on the island, in Achilles’ honour. But there are others, who are forced to come to this island by sea storms. As they have no sacrificial animals, but wish to get them from the god of the island himself, they consult Achilles' oracle. They ask permission to slaughter the victims chosen from among the animals that graze freely on the island, and to deposit in exchange the price which they consider fair. But in case the oracle denies them permission, because there is an oracle here, they add something to the price offered, and if the oracle refuses again, they add something more, until at last, the oracle agrees that the price is sufficient. And then the victim doesn’t run away any more, but waits willingly to be caught. So, there is a great quantity of silver there, consecrated to the hero, as price for the sacrificial victims. To some of the people who come to this island, Achilles appears in dreams, to others he would appear even during their navigation, if they were not too far away, and would instruct them as to which part of the island they would better anchor their ships. The Greek geographer Dionysius Periegetes, who lived probably during the first century AD, wrote that the island was called Leuce "because the wild animals which live there are white. It is said that there, in Leuce island, reside the souls of Achilles and other heroes, and that they wander through the uninhabited valleys of this island; this is how Jove rewarded the men who had distinguished themselves through their virtues, because through virtue they had acquired everlasting honour". Similarly, others relate the island's name to its white cliffs, snakes or birds dwelling there. Pausanias has been told that the island is "covered with forests and full of animals, some wild, some tame. In this island there is also Achilles' temple and his statue". Leuce had also a reputation as a place of healing. Pausanias reports that the Delphic Pythia sent a lord of Croton to be cured of a chest wound. Ammianus Marcellinus attributes the healing to waters (aquae) on the island.A number of important commercial port cities of the Greek waters were dedicated to Achilles. Herodotus, Pliny the Elder and Strabo reported on the existence of a town Achílleion (Ἀχίλλειον), built by settlers from Mytilene in the sixth century BC, close to the hero's presumed burial mound in the Troad. Later attestations point to an Achílleion in Messenia (according to Stephanus Byzantinus) and an Achílleios (Ἀχίλλειος) in Laconia. Nicolae Densuşianu recognized a connection to Achilles in the names of Aquileia and of the northern arm of the Danube delta, called Chilia (presumably from an older Achileii), though his conclusion, that Leuce had sovereign rights over the Black Sea, evokes modern rather than archaic sea-law.The kings of Epirus claimed to be descended from Achilles through his son, Neoptolemus. Alexander the Great, son of the Epirote princess Olympias, could therefore also claim this descent, and in many ways strove to be like his great ancestor. He is said to have visited the tomb of Achilles at Achilleion while passing Troy. In AD 216 the Roman Emperor Caracalla, while on his way to war against Parthia, emulated Alexander by holding games around Achilles' tumulus. == Reception during antiquity == === Achilles in Greek tragedy === The Greek tragedian Aeschylus wrote a trilogy of plays about Achilles, given the title Achilleis by modern scholars. The tragedies relate the deeds of Achilles during the Trojan War, including his defeat of Hector and eventual death when an arrow shot by Paris and guided by Apollo punctures his heel. Extant fragments of the Achilleis and other Aeschylean fragments have been assembled to produce a workable modern play. The first part of the Achilleis trilogy, The Myrmidons, focused on the relationship between Achilles and chorus, who represent the Achaean army and try to convince Achilles to give up his quarrel with Agamemnon; only a few lines survive today. In Plato's Symposium, Phaedrus points out that Aeschylus portrayed Achilles as the lover and Patroclus as the beloved; Phaedrus argues that this is incorrect because Achilles, being the younger and more beautiful of the two, was the beloved, who loved his lover so much that he chose to die to revenge him.The tragedian Sophocles also wrote The Lovers of Achilles, a play with Achilles as the main character. Only a few fragments survive.Towards the end of the 5th century BC, a more negative view of Achilles emerges in Greek drama; Euripides refers to Achilles in a bitter or ironic tone in Hecuba, Electra, and Iphigenia in Aulis. === Achilles in Greek philosophy === The philosopher Zeno of Elea centered one of his paradoxes on an imaginary footrace between "swift-footed" Achilles and a tortoise, by which he attempted to show that Achilles could not catch up to a tortoise with a head start, and therefore that motion and change were impossible. As a student of the monist Parmenides and a member of the Eleatic school, Zeno believed time and motion to be illusions. === Achilles in Roman and medieval literature === The Romans, who traditionally traced their lineage to Troy, took a highly negative view of Achilles. Virgil refers to Achilles as a savage and a merciless butcher of men, while Horace portrays Achilles ruthlessly slaying women and children. Other writers, such as Catullus, Propertius, and Ovid, represent a second strand of disparagement, with an emphasis on Achilles' erotic career. This strand continues in Latin accounts of the Trojan War by writers such as Dictys Cretensis and Dares Phrygius and in Benoît de Sainte-Maure's Roman de Troie and Guido delle Colonne's Historia destructionis Troiae, which remained the most widely read and retold versions of the Matter of Troy until the 17th century. Achilles was described by the Byzantine chronicler Leo the Deacon, not as Hellene, but as Scythian, while according to the Byzantine author John Malalas, his army was made up of a tribe previously known as Myrmidons and later as Bulgars. == Achilles in modern literature and arts == === Literature === Achilles appears in Dante's Inferno (composed 1308–1320). He is seen in Hell's second Circle of Lust. Achilles is portrayed as a former hero who has become lazy and devoted to the love of Patroclus, in William Shakespeare's Troilus and Cressida (1602). The French dramatist Thomas Corneille wrote a tragedy La Mort d'Achille (1673). Achilles is the subject of the poem Achilleis (1799), a fragment by Johann Wolfgang von Goethe. Achilles is mentioned in Tennyson's poem "Ulysses" (published in 1842): "[…] we shall touch the happy isles and meet there the great Achilles whom we knew." In 1899, the Polish playwright, painter and poet Stanisław Wyspiański published a national drama, based on Polish history, named Achilles. In 1921, Edward Shanks published The Island of Youth and Other Poems, concerned among others with Achilles. The 1983 novel Kassandra by Christa Wolf also treats the death of Achilles. Akhilles is killed by a poisoned Kentaur arrow shot by Kassandra in Marion Zimmer Bradley's novel The Firebrand (1987). Achilles is one of various 'narrators' in Colleen McCullough's novel The Song of Troy (1998). The Death of Achilles (Смерть Ахиллеса, 1998) is an historical detective novel by Russian writer Boris Akunin that alludes to various figures and motifs from the Iliad. The character Achilles in Ender's Shadow (1999), by Orson Scott Card, shares his namesake's cunning mind and ruthless attitude. Achilles is one of the main characters in Dan Simmons's novels Ilium (2003) and Olympos (2005). Achilles is a major supporting character in David Gemmell's Troy series of books (2005-2007). Achilles is the main character in David Malouf's novel Ransom (2009). The ghost of Achilles appears in Rick Riordan's The Last Olympian (2009). He warns Percy Jackson about the Curse of Achilles and its side effects. Achilles is a main character in Terence Hawkins' 2009 novel The Rage of Achilles. Achilles is a major character in Madeline Miller's debut novel, The Song of Achilles (2011), which won the 2012 Orange Prize for Fiction. The novel explores the relationship between Patroclus and Achilles from boyhood to the fateful events of the Iliad. Achilles appears in the light novel series Fate/Apocrypha (2012–2014) as the Rider of Red. === Visual arts === Achilles with the Daughters of Lycomedes is a subject treated in paintings by Anthony van Dyck (before 1618; Museo del Prado, Madrid) and Nicolas Poussin (c. 1652; Museum of Fine Arts, Boston) among others. Peter Paul Rubens has authored a series of works on the life of Achilles, comprising the titles: Thetis dipping the infant Achilles into the river Styx, Achilles educated by the centaur Chiron, Achilles recognized among the daughters of Lycomedes, The wrath of Achilles, The death of Hector, Thetis receiving the arms of Achilles from Vulcanus, The death of Achilles (Museum Boijmans Van Beuningen, Rotterdam), and Briseis restored to Achilles (Detroit Institute of Arts; all c. 1630–1635) Pieter van Lint, "Achilles Discovered among the Daughters of Lycomedes", 1645, at the Israel Museum, Jerusalem Dying Achilles is a sculpture created by Christophe Veyrier (c. 1683; Victoria and Albert Museum, London). The Rage of Achilles is a fresco by Giovanni Battista Tiepolo (1757, Villa Valmarana ai Nani, Vicenza). Eugène Delacroix painted a version of The Education of Achilles for the ceiling of the Paris Palais Bourbon (1833–1847), one of the seats of the French Parliament. Arthur Kaan created a statue group Achilles and Penthesilea (1895; Vienna). Achilleus (1908) is a lithography by Max Slevogt. === Music === Achilles has been frequently the subject of operas, ballets and related genres. Operas titled Deidamia were composed by Francesco Cavalli (1644) and George Frideric Handel (1739). Achille et Polyxène (Paris 1687) is an opera begun by Jean-Baptiste Lully and finished by Pascal Collasse. Achille e Deidamia (Naples 1698) is an opera, composed by Alessandro Scarlatti. Achilles (London 1733) is a ballad opera, written by John Gay, parodied by Thomas Arne as Achilles in petticoats in 1773. Achille in Sciro is a libretto by Metastasio, composed by Domenico Sarro for the inauguration of the Teatro di San Carlo (Naples, 4 November 1737). An even earlier composition is from Antonio Caldara (Vienna 1736). Later operas on the same libretto were composed by Leonardo Leo (Turin 1739), Niccolò Jommelli (Vienna 1749 and Rome 1772), Giuseppe Sarti (Copenhagen 1759 and Florence 1779), Johann Adolph Hasse (Naples 1759), Giovanni Paisiello (St. Petersburg 1772), Giuseppe Gazzaniga (Palermo 1781) and many others. It has also been set to music as Il Trionfo della gloria. Achille (Vienna 1801) is an opera by Ferdinando Paër on a libretto by Giovanni de Gamerra. Achille à Scyros (Paris 1804) is a ballet by Pierre Gardel, composed by Luigi Cherubini. Achilles, oder Das zerstörte Troja ("Achilles, or Troy Destroyed", Bonn 1885) is an oratorio by the German composer Max Bruch. Achilles auf Skyros (Stuttgart 1926) is a ballet by the Austrian-British composer and musicologist Egon Wellesz. Achilles' Wrath is a concert piece by Sean O'Loughlin. Achilles Last Stand a track on the 1976 Led Zeppelin album Presence. Achilles Come Down is a song on the 2017 Gang of Youths album Go Farther in Lightness. === Film and Television === In films Achilles has been portrayed in the following films and television series: Th 1924 film Helena by Carlo Aldini The 1954 film Ulysses by Piero Lulli The 1956 film Helen of Troy by Stanley Baker The 1961 film The Trojan Horse by Arturo Dominici The 1962 film The Fury of Achilles by Gordon Mitchell The 1997 television miniseries The Odyssey by Richard Trewett The 2003 television miniseries Helen of Troy by Joe Montana The 2004 film Troy by Brad Pitt The 2018 TV series Troy: Fall of a City by David Gyasi === Architecture === In 1890, Elisabeth of Bavaria, Empress of Austria, had a summer palace built in Corfu. The building is named the Achilleion, after Achilles. Its paintings and statuary depict scenes from the Trojan War, with particular focus on Achilles. == Namesakes == The name of Achilles has been used for at least nine Royal Navy warships since 1744 - both as HMS Achilles and with the French spelling HMS Achille. A 60-gun ship of that name served at the Battle of Belleisle in 1761 while a 74-gun ship served at the Battle of Trafalgar. Other battle honours include Walcheren 1809. An armored cruiser of that name served in the Royal Navy during the First World War. HMNZS Achilles was a Leander-class cruiser which served with the Royal New Zealand Navy in World War II. It became famous for its part in the Battle of the River Plate, alongside HMS Ajax and HMS Exeter. In addition to earning the battle honour 'River Plate', HMNZS Achilles also served at Guadalcanal 1942–43 and Okinawa in 1945. After returning to the Royal Navy, the ship was sold to the Indian Navy in 1948 but when she was scrapped parts of the ship were saved and preserved in New Zealand. A species of lizard, Anolis achilles, which has widened heel plates, is named for Achilles. == Gallery == == References == == Further reading == Ileana Chirassi Colombo (1977), "Heroes Achilleus – Theos Apollon."

### Instruction: retrieve labels for this: Abraham Lincoln (February 12, 1809 – April 15, 1865) was an American statesman and lawyer who served as the 16th President of the United States from March 1861 until his assassination in April 1865. Lincoln led the United States through the American Civil War—its bloodiest war and perhaps its greatest moral, constitutional, and political crisis. In doing so, he preserved the Union, abolished slavery, strengthened the federal government, and modernized the economy. Born in Hodgenville, Kentucky, Lincoln grew up on the western frontier in Kentucky and Indiana. Largely self-educated, he became a lawyer in Illinois, a Whig Party leader, and was elected to the Illinois House of Representatives, in which he served for eight years. Elected to the United States House of Representatives in 1846, Lincoln promoted rapid modernization of the economy and opposed the Mexican–American War. After a single term, he returned to Illinois and resumed his successful law practice. Reentering politics in 1854, he became a leader in building the new Republican Party, which had a statewide majority in Illinois. As part of the 1858 campaign for US Senator from Illinois, Lincoln took part in a series of highly publicized debates with his opponent and rival, Democrat Stephen A. Douglas; Lincoln spoke out against the expansion of slavery, but lost the race to Douglas. In 1860, Lincoln secured the Republican Party presidential nomination as a moderate from a swing state, though most delegates originally favored other candidates. Though he gained very little support in the slaveholding states of the South, he swept the North and was elected president in 1860. Though there were attempts to bridge the differences between North and South, ultimately Lincoln's victory prompted seven southern slave states to secede from the United States and form the Confederate States of America before he moved into the White House. U.S. troops refused to leave Fort Sumter, a fort located in Charleston, South Carolina, after the secession of the Southern States. The resulting Confederate attack on Fort Sumter inspired the North to rally behind the Union. As the leader of the moderate faction of the Republican Party, Lincoln confronted Radical Republicans, who demanded harsher treatment of the South; War Democrats, who rallied a large faction of former opponents into his camp; anti-war Democrats (called Copperheads), who despised him; and irreconcilable secessionists, who plotted his assassination. Lincoln fought back by pitting his opponents against each other, by carefully planned political patronage and by appealing to the American people with his powers of oratory. His Gettysburg Address became an iconic endorsement of nationalism, republicanism, equal rights, liberty, and democracy. He suspended habeas corpus, leading to the controversial Ex parte Merryman decision, and he averted potential British intervention by defusing the Trent Affair. Lincoln closely supervised the war effort, especially the selection of generals, including his most successful general, Ulysses S. Grant. He made major decisions on Union war strategy, including a naval blockade that shut down the South's trade. As the war progressed, his complex moves toward ending slavery included the Emancipation Proclamation of 1863; Lincoln used the U.S. Army to protect escaped slaves, encouraged the border states to outlaw slavery, and pushed through Congress the Thirteenth Amendment to the United States Constitution, which permanently outlawed slavery. An astute politician deeply involved with power issues in each state, Lincoln reached out to the War Democrats and managed his own re-election campaign in the 1864 presidential election. Anticipating the war's conclusion, Lincoln pushed a moderate view of Reconstruction, seeking to reunite the nation speedily through a policy of generous reconciliation in the face of lingering and bitter divisiveness. On April 14, 1865, five days after the surrender of Confederate general Robert E. Lee, Lincoln was shot by Confederate sympathizer John Wilkes Booth and died the next day. Lincoln has been consistently ranked both by scholars and the public as among the greatest U.S. presidents. == Family and childhood == === Early life and ancestry === Abraham Lincoln was born on February 12, 1809, as the second child of Thomas and Nancy Hanks Lincoln, in a one-room log cabin on the Sinking Spring Farm near Hodgenville, Kentucky. He was a descendant of Samuel Lincoln, an Englishman who migrated from Hingham, Norfolk, to its namesake of Hingham, Massachusetts, in 1638. Samuel's grandson and great-grandson began the family's western migration, which passed through New Jersey, Pennsylvania, and Virginia. Lincoln's paternal grandfather and namesake, Captain Abraham Lincoln, moved the family from Virginia to Jefferson County, Kentucky, in the 1780s. Captain Lincoln was killed in an Indian raid in 1786. His children, including eight-year-old Thomas, the future president's father, witnessed the attack. After his father's murder, Thomas was left to make his own way on the frontier, working at odd jobs in Kentucky and in Tennessee, before settling with members of his family in Hardin County, Kentucky, in the early 1800s. Lincoln's mother, Nancy, is widely assumed to have been the daughter of Lucy Hanks, although no record of Nancy Hanks' birth has ever been found. According to William Ensign Lincoln's book The Ancestry of Abraham Lincoln, Nancy was the daughter of Joseph Hanks; however, the debate continues over whether she was born out of wedlock. Still another researcher, Adin Baber, claims that Nancy Hanks was the daughter of Abraham Hanks and Sarah Harper of Virginia.Thomas Lincoln and Nancy Hanks were married on June 12, 1806, in Washington County, and moved to Elizabethtown, Kentucky, following their marriage. They became the parents of three children: Sarah, born on February 10, 1807; Abraham, on February 12, 1809; and another son, Thomas, who died in infancy. Thomas Lincoln bought or leased several farms in Kentucky, including the Sinking Spring farm, where Abraham was born; however, a land title dispute soon forced the Lincolns to move. In 1811, the family moved eight miles (13 km) north, to Knob Creek Farm, where Thomas acquired title to 230 acres (93 ha) of land. In 1815 a claimant in another land dispute sought to eject the family from the farm. Of the 816.5 acres (330.4 ha) that Thomas held in Kentucky, he lost all but 200 acres (81 ha) of his land in court disputes over property titles. Frustrated over the lack of security provided by the Kentucky title survey system in the courts, Thomas sold the remaining land he held in Kentucky in 1814, and began planning a move to Indiana, where the land survey process was more reliable and the ability for an individual to retain land titles was more secure.In 1816, the family moved north across the Ohio River to Indiana, a free, non-slaveholding territory, where they settled in an "unbroken forest" in Hurricane Township, Perry County. (Their land in southern Indiana became part of Spencer County, Indiana, when the county was established in 1818.) The farm is preserved as part of the Lincoln Boyhood National Memorial. In 1860, Lincoln noted that the family's move to Indiana was "partly on account of slavery"; but mainly due to land title difficulties in Kentucky. During the family's years in Kentucky and Indiana, Thomas Lincoln worked as a farmer, cabinetmaker, and carpenter. He owned farms, several town lots and livestock, paid taxes, sat on juries, appraised estates, served on country slave patrols, and guarded prisoners. Thomas and Nancy Lincoln were also members of a Separate Baptists church, which had restrictive moral standards and opposed alcohol, dancing, and slavery. Within a year of the family's arrival in Indiana, Thomas claimed title to 160 acres (65 ha) of Indiana land. Despite some financial challenges he eventually obtained clear title to 80 acres (32 ha) of land in what became known as the Little Pigeon Creek Community in Spencer County. Prior to the family's move to Illinois in 1830, Thomas had acquired an additional twenty acres of land adjacent to his property. Several significant family events took place during Lincoln's youth in Indiana. On October 5, 1818, Nancy Lincoln died of milk sickness, leaving eleven-year-old Sarah in charge of a household that included her father, nine-year-old Abraham, and Dennis Hanks, Nancy's nineteen-year-old orphaned cousin. On December 2, 1819, Lincoln's father married Sarah "Sally" Bush Johnston, a widow from Elizabethtown, Kentucky, with three children of her own. Abraham became very close to his stepmother, whom he referred to as "Mother". Those who knew Lincoln as a teenager later recalled him being very distraught over his sister Sarah's death on January 20, 1828, while giving birth to a stillborn son.As a youth, Lincoln disliked the hard labor associated with frontier life. Some of his neighbors and family members thought for a time that he was lazy for all his "reading, scribbling, writing, ciphering, writing Poetry, etc.", and must have done it to avoid manual labor. His stepmother also acknowledged he did not enjoy "physical labor", but loved to read. Lincoln was largely self-educated. His formal schooling from several itinerant teachers was intermittent, the aggregate of which may have amounted to less than a year; however, he was an avid reader and retained a lifelong interest in learning. Family, neighbors, and schoolmates of Lincoln's youth recalled that he read and reread the King James Bible, Aesop's Fables, John Bunyan's The Pilgrim's Progress, Daniel Defoe's Robinson Crusoe, Mason Locke Weems's The Life of Washington, and The Autobiography of Benjamin Franklin, among others.As he grew into his teens, Lincoln took responsibility for the chores expected of him as one of the boys in the household. He also complied with the customary obligation of a son giving his father all earnings from work done outside the home until the age of twenty-one. Abraham became adept at using an axe. Tall for his age, Lincoln was also strong and athletic. He attained a reputation for brawn and audacity after a very competitive wrestling match with the renowned leader of a group of ruffians known as "the Clary's Grove boys".In early March 1830, partly out of fear of a milk sickness outbreak along the Ohio River, several members of the extended Lincoln family moved west to Illinois, a non-slaveholding state, and settled in Macon County, 10 miles (16 km) west of Decatur. Historians disagree on who initiated the move; Thomas Lincoln had no obvious reason to leave Indiana, and one possibility is that other members of the family, including Dennis Hanks, might not have attained the stability and steady income that Thomas Lincoln had. After the family relocated to Illinois, Abraham became increasingly distant from his father, in part because of his father's lack of education, but occasionally lent him money. In 1831, as Thomas and other members of the family prepared to move to a new homestead in Coles County, Illinois, Abraham was old enough to make his own decisions and struck out on his own. Traveling down the Sangamon River, he ended up in the village of New Salem in Sangamon County. Later that spring, Denton Offutt, a New Salem merchant, hired Lincoln and some friends to take goods by flatboat from New Salem to New Orleans via the Sangamon, Illinois, and Mississippi rivers. After arriving in New Orleans—and witnessing slavery firsthand—Lincoln returned to New Salem, where he remained for the next six years. === Marriage and children === According to some sources, Lincoln's first romantic interest was Ann Rutledge, whom he met when he first moved to New Salem; these sources indicate that by 1835, they were in a relationship but not formally engaged. She died at the age of 22 on August 25, 1835, most likely of typhoid fever. In the early 1830s, he met Mary Owens from Kentucky when she was visiting her sister.Late in 1836, Lincoln agreed to a match with Mary if she returned to New Salem. Mary did return in November 1836, and Lincoln courted her for a time; however, they both had second thoughts about their relationship. On August 16, 1837, Lincoln wrote Mary a letter suggesting he would not blame her if she ended the relationship. She never replied and the courtship ended.In 1840, Lincoln became engaged to Mary Todd, who was from a wealthy slave-holding family in Lexington, Kentucky. They met in Springfield, Illinois in December 1839 and were engaged the following December. A wedding set for January 1, 1841, was canceled when the two broke off their engagement at Lincoln's initiative. They later met again at a party and married on November 4, 1842, in the Springfield mansion of Mary's married sister. While preparing for the nuptials and feeling anxiety again, Lincoln, when asked where he was going, replied, "To hell, I suppose." In 1844, the couple bought a house in Springfield near Lincoln's law office. Mary Todd Lincoln kept house, often with the help of a relative or hired servant girl.He was an affectionate, though often absent, husband and father of four children. Robert Todd Lincoln was born in 1843 and Edward Baker Lincoln (Eddie) in 1846. Edward died on February 1, 1850, in Springfield, probably of tuberculosis. "Willie" Lincoln was born on December 21, 1850, and died of a fever on February 20, 1862. The Lincolns' fourth son, Thomas "Tad" Lincoln, was born on April 4, 1853, and died of heart failure at the age of 18 on July 16, 1871. Robert was the only child to live to adulthood and have children. The Lincolns' last descendant, great-grandson Robert Todd Lincoln Beckwith, died in 1985. Lincoln "was remarkably fond of children", and the Lincolns were not considered to be strict with their own.The deaths of their sons had profound effects on both parents. Lincoln later asked a Union officer, “Do you ever find yourself talking with the dead? Since Willie's death I catch myself every day involuntarily talking with him, as if he were with me." To Mary, he remarked when the war was won, "We must both be more cheerful in the future -- between the war and the loss of our darling Willie, we have both been very miserable." Hours later, the Lincolns went to Ford's Theater. Later in life, Mary struggled with the stresses of losing her husband and sons, and Robert Lincoln committed her temporarily to a mental health asylum in 1875. Abraham Lincoln suffered from "melancholy", a condition which now is referred to as clinical depression.Lincoln's father-in-law and others of the Todd family were either slave owners or slave traders. Lincoln was close to the Todds, and he and his family occasionally visited the Todd estate in Lexington.During his term as President of the United States, Mary was known to cook for Lincoln often. Since she was raised by a wealthy family, her cooking abilities were simple, but satisfied Lincoln's tastes, which included, particularly, imported oysters. == Early career and militia service == In 1832, at age 23, Lincoln and a partner (Denton Offutt) bought a small general store on credit in New Salem, Illinois. Although the economy was booming in the region, the business struggled and Lincoln eventually sold his share. That March he began his political career with his first campaign for the Illinois General Assembly. He had attained local popularity and could draw crowds as a natural raconteur in New Salem, though he lacked an education, powerful friends, and money, which may be why he lost. He advocated navigational improvements on the Sangamon River.Before the election, Lincoln served as a captain in the Illinois Militia during the Black Hawk War. Following his return, Lincoln continued his campaign for the August 6 election for the Illinois General Assembly. At 6 feet 4 inches (193 cm), he was tall and "strong enough to intimidate any rival". At his first speech, when he saw a supporter in the crowd being attacked, Lincoln grabbed the assailant by his "neck and the seat of his trousers" and threw him. Lincoln finished eighth out of 13 candidates (the top four were elected), though he received 277 of the 300 votes cast in the New Salem precinct.Lincoln served as New Salem's postmaster and later as county surveyor, all the while reading voraciously. He then decided to become a lawyer and began teaching himself law by reading Blackstone's Commentaries on the Laws of England and other law books. Of his learning method, Lincoln stated: "I studied with nobody". His second campaign in 1834 was successful. He won election to the state legislature; though he ran as a Whig, many Democrats favored him over a more powerful Whig opponent. Admitted to the Illinois bar in 1836, he moved to Springfield, Illinois, and began to practice law under John T. Stuart, Mary Todd's cousin. Lincoln became an able and successful lawyer with a reputation as a formidable adversary during cross-examinations and closing arguments. He partnered with Stephen T. Logan from 1841 until 1844. Then Lincoln began his practice with William Herndon, whom Lincoln thought "a studious young man".Successful on his second run for office, Lincoln served four successive terms in the Illinois House of Representatives as a Whig representative from Sangamon County. He supported the construction of the Illinois and Michigan Canal, which he remained involved with later as a Canal Commissioner. In the 1835–36 legislative session, he voted to expand suffrage to white males, whether landowners or not. He was known for his "free soil" stance of opposing both slavery and abolitionism. He first articulated this in 1837, saying, "[The] Institution of slavery is founded on both injustice and bad policy, but the promulgation of abolition doctrines tends rather to increase than abate its evils." His stance closely followed Henry Clay in supporting the American Colonization Society program of making the abolition of slavery practical by its advocation and helping the freed slaves to settle in Liberia in Africa. == U.S. House of Representatives, 1847–49 == From the early 1830s, Lincoln was a steadfast Whig and professed to friends in 1861 to be "an old line Whig, a disciple of Henry Clay". The party, including Lincoln, favored economic modernization in banking, protective tariffs to fund internal improvements including railroads, and espoused urbanization as well.Lincoln ran for the Whig nomination for Illinois's 7th district of the U.S. House of Representatives in 1843, but was defeated by John J. Hardin. However, Lincoln won support for the principle of rotation, whereby Hardin would retire after only one term to allow for the nomination of another candidate. Lincoln hoped that this arrangement would lead to his nomination in 1846. Lincoln was indeed elected to the House of Representatives in 1846, where he served one two-year term. He was the only Whig in the Illinois delegation, but he showed his party loyalty by participating in almost all votes and making speeches that echoed the party line. Lincoln, in collaboration with abolitionist Congressman Joshua R. Giddings, wrote a bill to abolish slavery in the District of Columbia with compensation for the owners, enforcement to capture fugitive slaves, and a popular vote on the matter. He abandoned the bill when it failed to garner sufficient Whig supporters.On foreign and military policy, Lincoln spoke out against the Mexican–American War, which he attributed to President Polk's desire for "military glory—that attractive rainbow, that rises in showers of blood". Lincoln also supported the Wilmot Proviso, which, if it had been adopted, would have banned slavery in any U.S. territory won from Mexico.Lincoln emphasized his opposition to Polk by drafting and introducing his Spot Resolutions. The war had begun with a Mexican slaughter of American soldiers in territory disputed by Mexico and the U.S. Polk insisted that Mexican soldiers had "invaded our territory and shed the blood of our fellow-citizens on our own soil". Lincoln demanded that Polk show Congress the exact spot on which blood had been shed and prove that the spot was on American soil.Congress never enacted the resolution or even debated it, the national papers ignored it, and it resulted in a loss of political support for Lincoln in his district. One Illinois newspaper derisively nicknamed him "spotty Lincoln". Lincoln later regretted some of his statements, especially his attack on the presidential war-making powers.Realizing Clay was unlikely to win the presidency, Lincoln, who had pledged in 1846 to serve only one term in the House, supported General Zachary Taylor for the Whig nomination in the 1848 presidential election. Taylor won and Lincoln hoped to be appointed Commissioner of the General Land Office, but that lucrative patronage job went to an Illinois rival, Justin Butterfield, considered by the administration to be a highly skilled lawyer, but in Lincoln's view, an "old fossil". The administration offered him the consolation prize of secretary or governor of the Oregon Territory. This distant territory was a Democratic stronghold, and acceptance of the post would have effectively ended his legal and political career in Illinois, so he declined and resumed his law practice. == Prairie lawyer == Lincoln returned to practicing law in Springfield, handling "every kind of business that could come before a prairie lawyer". Twice a year for 16 years, 10 weeks at a time, he appeared in county seats in the midstate region when the county courts were in session. Lincoln handled many transportation cases in the midst of the nation's western expansion, particularly the conflicts arising from the operation of river barges under the many new railroad bridges. As a riverboat man, Lincoln initially favored those interests, but ultimately represented whoever hired him. In fact, he later represented a bridge company against a riverboat company in a landmark case involving a canal boat that sank after hitting a bridge. In 1849, he received a patent for a flotation device for the movement of boats in shallow water. The idea was never commercialized, but Lincoln is the only president to hold a patent.In 1851, he represented the Alton & Sangamon Railroad in a dispute with one of its shareholders, James A. Barret, who had refused to pay the balance on his pledge to buy shares in the railroad on the grounds that the company had changed its original train route. Lincoln successfully argued that the railroad company was not bound by its original charter extant at the time of Barret's pledge; the charter was amended in the public interest to provide a newer, superior, and less expensive route, and the corporation retained the right to demand Barret's payment. The decision by the Illinois Supreme Court has been cited by numerous other courts in the nation. Lincoln appeared before the Illinois Supreme Court in 175 cases, in 51 as sole counsel, of which 31 were decided in his favor. From 1853 to 1860, another of Lincoln's largest clients was the Illinois Central Railroad. Lincoln's reputation with clients gave rise to his nickname "Honest Abe."Lincoln's most notable criminal trial occurred in 1858 when he defended William "Duff" Armstrong, who was on trial for the murder of James Preston Metzker. The case is famous for Lincoln's use of a fact established by judicial notice in order to challenge the credibility of an eyewitness. After an opposing witness testified seeing the crime in the moonlight, Lincoln produced a Farmers' Almanac showing the moon was at a low angle, drastically reducing visibility. Based on this evidence, Armstrong was acquitted.Lincoln rarely raised objections in the courtroom; but in an 1859 case, where he defended a cousin, Peachy Harrison, who was accused of stabbing another to death, Lincoln angrily protested the judge's decision to exclude evidence favorable to his client. Instead of holding Lincoln in contempt of court as was expected, the judge, a Democrat, reversed his ruling, allowing the evidence and acquitting Harrison. == Republican politics 1854–60 == === Emergence as Republican leader === The debate over the status of slavery in the territories exacerbated sectional tensions between the slave-holding South and the North, and the Compromise of 1850 failed to defuse the issue. In the early 1850s, Lincoln supported efforts for sectional mediation, and his 1852 eulogy for Henry Clay focused on the latter's support for gradual emancipation and opposition to "both extremes" on the slavery issue. As the 1850s progressed, the debate over slavery in the Nebraska Territory and Kansas Territory became particularly acrimonious, and Senator Stephen A. Douglas of Illinois proposed popular sovereignty as a compromise measure; the proposal would take the issue of slavery out of the hands of Congress by allowing the electorate of each territory to decide the status of slavery themselves. The proposal alarmed many Northerners, who hoped to stop the spread of slavery into the territories. Despite this Northern opposition, Douglas's Kansas–Nebraska Act narrowly passed Congress in May 1854.For months after its passage, Lincoln did not publicly comment on the Kansas–Nebraska Act, but he came to strongly oppose it. On October 16, 1854, in his "Peoria Speech", Lincoln declared his opposition to slavery, which he repeated en route to the presidency. Speaking in his Kentucky accent, with a very powerful voice, he said the Kansas Act had a "declared indifference, but as I must think, a covert real zeal for the spread of slavery. I cannot but hate it. I hate it because of the monstrous injustice of slavery itself. I hate it because it deprives our republican example of its just influence in the world ..." Lincoln's attacks on the Kansas–Nebraska Act marked his return to political life.Nationally, the Whigs were irreparably split by the Kansas–Nebraska Act and other efforts to compromise on the slavery issue. Reflecting the demise of his party, Lincoln would write in 1855, "I think I am a Whig, but others say there are no Whigs, and that I am an abolitionist [...] I do no more than oppose the extension of slavery." Drawing on the antislavery portion of the Whig Party, and combining Free Soil, Liberty, and antislavery Democratic Party members, the new Republican Party formed as a northern party dedicated to antislavery. Lincoln resisted early attempts to recruit him to the new party, fearing that it would serve as a platform for extreme abolitionists. Lincoln also still hoped to rejuvenate the ailing Whig Party, though he bemoaned his party's growing closeness with the nativist Know Nothing movement.In the 1854 elections, Lincoln was elected to the Illinois legislature but declined to take his seat. In the aftermath of the elections, which showed the power and popularity of the movement opposed to the Kansas–Nebraska Act, Lincoln instead sought election to the United States Senate. At that time, senators were elected by the state legislature. After leading in the first six rounds of voting, but unable to obtain a majority, Lincoln instructed his backers to vote for Lyman Trumbull. Trumbull was an antislavery Democrat, and had received few votes in the earlier ballots; his supporters, also antislavery Democrats, had vowed not to support any Whig. Lincoln's decision to withdraw enabled his Whig supporters and Trumbull's antislavery Democrats to combine and defeat the mainstream Democratic candidate, Joel Aldrich Matteson.In part due to the ongoing violent political confrontations in the Kansas, opposition to the Kansas–Nebraska Act remained strong in Illinois and throughout the North. As the 1856 elections approached, Lincoln abandoned the defunct Whig Party in favor of the Republicans. He attended the May 1856 Bloomington Convention, which formally established the Illinois Republican Party. The convention platform asserted that Congress had the right to regulate slavery in the territories and called for the immediate admission of Kansas as a free state. Lincoln gave the final speech of the convention, in which he endorsed the party platform and called for the preservation of the Union. At the June 1856 Republican National Convention, Lincoln received significant support on the vice presidential ballot, though the party nominated a ticket of John C. Frémont and William Dayton. Lincoln strongly supported the Republican ticket, campaigning for the party throughout Illinois. The Democrats nominated former Ambassador James Buchanan, who had been out of the country since 1853 and thus had avoided the debate over slavery in the territories, while the Know Nothings nominated former Whig President Millard Fillmore. In the 1856 elections, Buchanan defeated both his challengers, but Frémont won several Northern states and Republican William Henry Bissell won election as Governor of Illinois. Though Lincoln did not himself win office, his vigorous campaigning had made him the leading Republican in Illinois. Eric Foner (2010) contrasts the abolitionists and anti-slavery Radical Republicans of the Northeast who saw slavery as a sin, with the conservative Republicans who thought it was bad because it hurt white people and blocked progress. Foner argues that Lincoln was a moderate in the middle, opposing slavery primarily because it violated the republicanism principles of the Founding Fathers, especially the equality of all men and democratic self-government as expressed in the Declaration of Independence.In March 1857, the Supreme Court issued its decision in Dred Scott v. Sandford. The opinion by Chief Justice Roger B. Taney held that blacks were not citizens and derived no rights from the Constitution. While many Democrats hoped that Dred Scott would end the dispute over slavery in the territories, the decision sparked further outrage in the North. Lincoln denounced the decision, alleging it was the product of a conspiracy of Democrats to support the Slave Power. Lincoln argued, "The authors of the Declaration of Independence never intended 'to say all were equal in color, size, intellect, moral developments, or social capacity', but they 'did consider all men created equal—equal in certain inalienable rights, among which are life, liberty, and the pursuit of happiness'." === Lincoln–Douglas debates and Cooper Union speech === Douglas was up for re-election in 1858, and Lincoln hoped to defeat the powerful Illinois Democrat. With the former Democrat Trumbull now serving as a Republican Senator, many in the party felt that a former Whig should be nominated in 1858, and Lincoln's 1856 campaigning and willingness to support Trumbull in 1854 had earned him favor in the party. Some eastern Republicans favored the reelection of Douglas for the Senate in 1858, since he had led the opposition to the Lecompton Constitution, which would have admitted Kansas as a slave state. But many Illinois Republicans resented this eastern interference. For the first time, Illinois Republicans held a convention to agree upon a Senate candidate, and Lincoln won the party's Senate nomination with little opposition.Accepting the nomination, Lincoln delivered his House Divided Speech, drawing on Mark 3:25, "A house divided against itself cannot stand. I believe this government cannot endure permanently half slave and half free. I do not expect the Union to be dissolved—I do not expect the house to fall—but I do expect it will cease to be divided. It will become all one thing, or all the other." The speech created an evocative image of the danger of disunion caused by the slavery debate, and rallied Republicans across the North. The stage was then set for the campaign for statewide election of the Illinois legislature which would, in turn, select Lincoln or Douglas as its U.S. senator. On being informed of Lincoln's nomination, Douglas stated "[Lincoln] is the strong man of the party...and if I beat him, my victory will be hardly won."The Senate campaign featured the seven Lincoln–Douglas debates of 1858, the most famous political debates in American history. The principals stood in stark contrast both physically and politically. Lincoln warned that "The Slave Power" was threatening the values of republicanism, and accused Douglas of distorting the values of the Founding Fathers that all men are created equal, while Douglas emphasized his Freeport Doctrine, that local settlers were free to choose whether to allow slavery or not, and accused Lincoln of having joined the abolitionists. The debates had an atmosphere of a prize fight and drew crowds in the thousands. Lincoln stated Douglas' popular sovereignty theory was a threat to the nation's morality and that Douglas represented a conspiracy to extend slavery to free states. Douglas said that Lincoln was defying the authority of the U.S. Supreme Court and the Dred Scott decision.Though the Republican legislative candidates won more popular votes, the Democrats won more seats, and the legislature re-elected Douglas to the Senate. Despite the bitterness of the defeat for Lincoln, his articulation of the issues gave him a national political reputation. In May 1859, Lincoln purchased the Illinois Staats-Anzeiger, a German-language newspaper which was consistently supportive; most of the state's 130,000 German Americans voted Democratic but there was Republican support that a German-language paper could mobilize. In the aftermath of the 1858 election, newspapers frequently mentioned Lincoln as a potential Republican presidential candidate in 1860, with William H. Seward, Salmon P. Chase, Edward Bates, and Simon Cameron looming as rivals for the nomination. While Lincoln was popular in the Midwest, he lacked support in the Northeast, and was unsure as to whether he should seek the presidency. In January 1860, Lincoln told a group of political allies that he would accept the 1860 presidential nomination if offered, and in the following months several local papers endorsed Lincoln for president.On February 27, 1860, New York party leaders invited Lincoln to give a speech at Cooper Union to a group of powerful Republicans. Lincoln argued that the Founding Fathers had little use for popular sovereignty and had repeatedly sought to restrict slavery. Lincoln insisted the moral foundation of the Republicans required opposition to slavery, and rejected any "groping for some middle ground between the right and the wrong". Despite his inelegant appearance—many in the audience thought him awkward and even ugly—Lincoln demonstrated an intellectual leadership that brought him into the front ranks of the party and into contention for the Republican presidential nomination. Journalist Noah Brooks reported, "No man ever before made such an impression on his first appeal to a New York audience."Historian Donald described the speech as a "superb political move for an unannounced candidate, to appear in one rival's (Seward) own state at an event sponsored by the second rival's (Chase) loyalists, while not mentioning either by name during its delivery". In response to an inquiry about his presidential intentions, Lincoln said, "The taste is in my mouth a little." === 1860 Presidential nomination and campaign === On May 9–10, 1860, the Illinois Republican State Convention was held in Decatur. Lincoln's followers organized a campaign team led by David Davis, Norman Judd, Leonard Swett, and Jesse DuBois, and Lincoln received his first endorsement to run for the presidency. Exploiting the embellished legend of his frontier days with his father (clearing the land and splitting fence rails with an ax), Lincoln's supporters adopted the label of "The Rail Candidate". In 1860 Lincoln described himself: "I am in height, six feet, four inches, nearly; lean in flesh, weighing, on an average, one hundred and eighty pounds; dark complexion, with coarse black hair, and gray eyes."On May 18, at the Republican National Convention in Chicago, Lincoln became the Republican candidate on the third ballot, beating candidates such as Seward and Chase. A former Democrat, Hannibal Hamlin of Maine, was nominated for Vice President to balance the ticket. Lincoln's success depended on his campaign team, his reputation as a moderate on the slavery issue, and his strong support for Whiggish programs of internal improvements and the protective tariff.On the third ballot Pennsylvania put him over the top. Pennsylvania iron interests were reassured by his support for protective tariffs. Lincoln's managers had been adroitly focused on this delegation as well as the others, while following Lincoln's strong dictate to "Make no contracts that bind me".Most Republicans agreed with Lincoln that the North was the aggrieved party, as the Slave Power tightened its grasp on the national government with the Dred Scott decision and the presidency of James Buchanan. Throughout the 1850s, Lincoln doubted the prospects of civil war, and his supporters rejected claims that his election would incite secession. Meanwhile, Douglas was selected as the candidate of the Northern Democrats. Delegates from 11 slave states walked out of the Democratic convention, disagreeing with Douglas' position on popular sovereignty, and ultimately selected incumbent Vice President John C. Breckinridge as their candidate. A group of former Whigs and Know Nothings formed the Constitutional Union Party and nominated John Bell of Tennessee. Lincoln and Douglas would compete for votes in the North, while Bell and Breckinridge primarily found support in the South.Lincoln had a highly effective campaign team who carefully projected his image as an ideal candidate. As Michael Martinez says: Lincoln and his political advisers manipulated his image and background....Sometimes he appeared as a straight-shooting, plain-talking, common-sense-wielding man of the people. His image as the "Rail Splitter" dates from this era. His supporters also portrayed him as "Honest Abe," the country fellow who was simply dressed and not especially polished or formal in his manner but who was as honest and trustworthy as his legs were long. Even Lincoln's tall, gangly frame was used to good advantage during the campaign as many drawings and posters show the candidates sprinting past his vertically challenged rivals. At other times, Lincoln appeared as a sophisticated, thoughtful, articulate, "presidential" candidate. Prior to the Republican convention, the Lincoln campaign began cultivating a nationwide youth organization, the Wide Awakes, which it used to generate popular support for Lincoln throughout the country to spearhead large voter registration drives, knowing that new voters and young voters tend to embrace new and young parties. As Lincoln's ideas of abolishing slavery grew, so did his supporters. People of the Northern states knew the Southern states would vote against Lincoln because of his ideas of anti-slavery and took action to rally supporters for Lincoln.As Douglas and the other candidates went through with their campaigns, Lincoln was the only one of them who gave no speeches. Instead, he monitored the campaign closely and relied on the enthusiasm of the Republican Party. The party did the leg work that produced majorities across the North, and produced an abundance of campaign posters, leaflets, and newspaper editorials. There were thousands of Republican speakers who focused first on the party platform, and second on Lincoln's life story, emphasizing his childhood poverty. The goal was to demonstrate the superior power of "free labor", whereby a common farm boy could work his way to the top by his own efforts. The Republican Party's production of campaign literature dwarfed the combined opposition; a Chicago Tribune writer produced a pamphlet that detailed Lincoln's life, and sold 100,000 to 200,000 copies. == Presidency == === 1860 election and secession === On November 6, 1860, Lincoln was elected the 16th president of the United States, beating Douglas, Breckinridge, and Bell. He was the first president from the Republican Party. His victory was entirely due to the strength of his support in the North and West; no ballots were cast for him in 10 of the 15 Southern slave states, and he won only two of 996 counties in all the Southern states.Lincoln received 1,866,452 votes, Douglas 1,376,957 votes, Breckinridge 849,781 votes, and Bell 588,789 votes. Turnout was 82.2 percent, with Lincoln winning the free Northern states, as well as California and Oregon. Douglas won Missouri, and split New Jersey with Lincoln. Bell won Virginia, Tennessee, and Kentucky, and Breckinridge won the rest of the South.Although Lincoln won only a plurality of the popular vote, his victory in the electoral college was decisive: Lincoln had 180 and his opponents added together had only 123. There were fusion tickets in which all of Lincoln's opponents combined to support the same slate of Electors in New York, New Jersey, and Rhode Island, but even if the anti-Lincoln vote had been combined in every state, Lincoln still would have won a majority in the Electoral College. As Lincoln's election became evident, secessionists made clear their intent to leave the Union before he took office the next March. On December 20, 1860, South Carolina took the lead by adopting an ordinance of secession; by February 1, 1861, Florida, Mississippi, Alabama, Georgia, Louisiana, and Texas followed. Six of these states then adopted a constitution and declared themselves to be a sovereign nation, the Confederate States of America. The upper South and border states (Delaware, Maryland, Virginia, North Carolina, Tennessee, Kentucky, Missouri, and Arkansas) listened to, but initially rejected, the secessionist appeal. President Buchanan and President-elect Lincoln refused to recognize the Confederacy, declaring secession illegal. The Confederacy selected Jefferson Davis as its provisional President on February 9, 1861.There were attempts at compromise. The Crittenden Compromise would have extended the Missouri Compromise line of 1820, dividing the territories into slave and free, contrary to the Republican Party's free-soil platform. Lincoln rejected the idea, saying, "I will suffer death before I consent ... to any concession or compromise which looks like buying the privilege to take possession of this government to which we have a constitutional right."Lincoln, however, did tacitly support the proposed Corwin Amendment to the Constitution, which passed Congress before Lincoln came into office and was then awaiting ratification by the states. That proposed amendment would have protected slavery in states where it already existed and would have guaranteed that Congress would not interfere with slavery without Southern consent. A few weeks before the war, Lincoln sent a letter to every governor informing them Congress had passed a joint resolution to amend the Constitution. Lincoln was open to the possibility of a constitutional convention to make further amendments to the Constitution. En route to his inauguration by train, Lincoln addressed crowds and legislatures across the North. The president-elect then evaded possible assassins in Baltimore, who were uncovered by Lincoln's head of security, Allan Pinkerton. On February 23, 1861, he arrived in disguise in Washington, D.C., which was placed under substantial military guard. Lincoln directed his inaugural address to the South, proclaiming once again that he had no intention, or inclination, to abolish slavery in the Southern states: Apprehension seems to exist among the people of the Southern States that by the accession of a Republican Administration their property and their peace and personal security are to be endangered. There has never been any reasonable cause for such apprehension. Indeed, the most ample evidence to the contrary has all the while existed and been open to their inspection. It is found in nearly all the published speeches of him who now addresses you. I do but quote from one of those speeches when I declare that "I have no purpose, directly or indirectly, to interfere with the institution of slavery in the States where it exists. I believe I have no lawful right to do so, and I have no inclination to do so." The President ended his address with an appeal to the people of the South: "We are not enemies, but friends. We must not be enemies ... The mystic chords of memory, stretching from every battlefield, and patriot grave, to every living heart and hearthstone, all over this broad land, will yet swell the chorus of the Union, when again touched, as surely they will be, by the better angels of our nature." The failure of the Peace Conference of 1861 signaled that legislative compromise was impossible. By March 1861, no leaders of the insurrection had proposed rejoining the Union on any terms. Meanwhile, Lincoln and the Republican leadership agreed that the dismantling of the Union could not be tolerated. Lincoln said as the war was ending: Both parties deprecated war, but one of them would make war rather than let the Nation survive, and the other would accept war rather than let it perish, and the war came. === The Civil War === The commander of Fort Sumter, South Carolina, Major Robert Anderson, sent a request for provisions to Washington, and the execution of Lincoln's order to meet that request was seen by the secessionists as an act of war. On April 12, 1861, Confederate forces fired on Union troops at Fort Sumter, forcing them to surrender, beginning the war. Historian Allan Nevins argued that the newly inaugurated Lincoln made three miscalculations: underestimating the gravity of the crisis, exaggerating the strength of Unionist sentiment in the South, and not realizing the Southern Unionists were insisting there be no invasion.William Tecumseh Sherman talked to Lincoln during inauguration week and was "sadly disappointed" at his failure to realize that "the country was sleeping on a volcano" and that the South was preparing for war. Historian David Herbert Donald concludes that, "His repeated efforts to avoid collision in the months between inauguration and the firing on Ft. Sumter showed he adhered to his vow not to be the first to shed fraternal blood. But he also vowed not to surrender the forts. The only resolution of these contradictory positions was for the confederates to fire the first shot; they did just that."On April 15, Lincoln called on all the states to send detachments totaling 75,000 troops to recapture forts, protect Washington, and "preserve the Union", which, in his view, still existed intact despite the actions of the seceding states. This call forced the states to choose sides. Virginia declared its secession and was rewarded with the Confederate capital, despite the exposed position of Richmond so close to Union lines. North Carolina, Tennessee, and Arkansas also voted for secession over the next two months. Secession sentiment was strong in Missouri and Maryland, but did not prevail; Kentucky tried to be neutral. The Confederate attack on Fort Sumter rallied Americans north of the Mason-Dixon line to the defense of the American nation. Historian Allan Nevins says: The thunderclap of Sumter produced a startling crystallization of Northern sentiment ... Anger swept the land. From every side came news of mass meetings, speeches, resolutions, tenders of business support, the muster of companies and regiments, the determined action of governors and legislatures. States sent Union regiments south in response to Lincoln's call to save the capital and confront the rebellion. On April 19, mobs in Baltimore, which controlled the rail links, attacked Union troops who were changing trains, and local leaders' groups later burned critical rail bridges to the capital. The Army responded by arresting local Maryland officials. Lincoln suspended the writ of habeas corpus in areas the army felt it needed to secure for troops to reach Washington. John Merryman, a Maryland official involved in hindering the U.S. troop movements, petitioned Supreme Court Chief Justice and Marylander, Roger B. Taney, author of the controversial pro-slavery Dred Scott opinion, to issue a writ of habeas corpus, and in June Taney, acting as a circuit judge and not speaking for the Supreme Court, issued the writ, because in his opinion only Congress could suspend the writ. Lincoln continued the army policy that the writ was suspended in limited areas despite the Ex parte Merryman ruling. === Greenbacks currency === Before the Civil War, the only money issued by the United States was gold and silver coins, and only such coins ("specie") were legal tender; that is, payment in that form had to be accepted. Paper currency in the form of banknotes was issued by privately owned banks. Greenbacks were paper currency (printed in green on the back) issued by the United States during the American Civil War, they were in two forms: Demand Notes, issued In July 1861, Congress authorized $50,000,000 in Demand Notes. They bore no interest, but could be redeemed for specie "on demand". They were not legal tender (before March 1862), but like Treasury Notes could be used to pay customs duties. Unlike private and state banknotes, Demand Notes were printed on both sides. The reverse side was printed in green ink, and so the Demand Notes were dubbed "greenbacks". Initially they were discounted relative to gold, but being fully redeemable in gold were soon at par. In December 1861, the government had to suspend redemption, and they declined. Chase authorized paying interest on Demand Notes, which sustained their value. Importers therefore continued to use Demand Notes in place of gold. In March 1862, Demand Notes were made legal tender. As Demand Notes were used to pay duties, they were taken out of circulation. By mid-1863, about 95% of them were gone. The other form of greenbacks where the United States Notes issued in 1862–1865. They were legal tender by law, but were not backed by gold or silver, only the credibility of the U.S. government. Could not be used to pay customs duties or interest on the public debt. === Union military strategy === After the Battle of Fort Sumter, Lincoln realized the importance of taking immediate executive control of the war and forming an overall Union military strategy to put down the rebellion. Lincoln encountered an unprecedented political and military crisis, and he responded as commander-in-chief, using unprecedented powers. He expanded his war powers, and imposed a blockade on all the Confederate shipping ports, disbursed funds before appropriation by Congress, and after suspending habeas corpus, arrested and imprisoned thousands of suspected Confederate sympathizers. Lincoln was supported by Congress and the northern public for these actions. In addition, Lincoln had to contend with reinforcing strong Union sympathies in the border slave states and keeping the war from becoming an international conflict. The war effort was the source of continued disparagement of Lincoln, and dominated his time and attention. From the start, it was clear that bipartisan support would be essential to success in the war effort, and any manner of compromise alienated factions on both sides of the aisle, such as the appointment of Republicans and Democrats to command positions in the Union Army. Copperheads criticized Lincoln for refusing to compromise on the slavery issue. Conversely, the Radical Republicans criticized him for moving too slowly in abolishing slavery. On August 6, 1861, Lincoln signed the Confiscation Act that authorized judiciary proceedings to confiscate and free slaves who were used to support the Confederate war effort. In practice, the law had little effect, but it did signal political support for abolishing slavery in the Confederacy.In late August 1861, General John C. Frémont, the 1856 Republican presidential nominee, issued, without consulting his superiors in Washington, a proclamation of martial law in Missouri. He declared that any citizen found bearing arms could be court-martialed and shot, and that slaves of persons aiding the rebellion would be freed. Frémont was already under a cloud with charges of negligence in his command of the Department of the West compounded with allegations of fraud and corruption. Lincoln overruled Frémont's proclamation. Lincoln believed that Fremont's emancipation was political, neither militarily necessary nor legal. After Lincoln acted, Union enlistments from Maryland, Kentucky, and Missouri increased by over 40,000 troops.In foreign policy, Lincoln's main goal was to stop military aid from countries abroad to the Confederacy. Lincoln left most diplomatic matters to his Secretary of State, William Seward. At times Seward was too bellicose, so for balance Lincoln maintained a close working relationship with Senator Charles Sumner, the chairman of the Senate Foreign Relations Committee. The Trent Affair of late 1861 threatened war with Great Britain. The U.S. Navy had illegally intercepted a British mail ship, the Trent, on the high seas and seized two Confederate envoys; Britain protested vehemently while the U.S. cheered. Lincoln ended the crisis by releasing the two diplomats. Biographer James G. Randall has dissected Lincoln's successful techniques: his restraint, his avoidance of any outward expression of truculence, his early softening of State Department's attitude toward Britain, his deference toward Seward and Sumner, his withholding of his own paper prepared for the occasion, his readiness to arbitrate, his golden silence in addressing Congress, his shrewdness in recognizing that war must be averted, and his clear perception that a point could be clinched for America's true position at the same time that full satisfaction was given to a friendly country. Lincoln painstakingly monitored the telegraphic reports coming into the War Department headquarters. He kept close tabs on all phases of the military effort, consulted with governors, and selected generals based on their past success (as well as their state and party). In January 1862, after many complaints of inefficiency and profiteering in the War Department, Lincoln replaced Simon Cameron with Edwin Stanton as War Secretary. Stanton centralized the War Department's activities, auditing and cancelling contracts, saving the federal government $17,000,000. Stanton was a staunchly Unionist pro-business conservative Democrat who moved toward the Radical Republican faction. Nevertheless, he worked more often and more closely with Lincoln than any other senior official. "Stanton and Lincoln virtually conducted the war together," say Thomas and Hyman.In terms of war strategy, Lincoln articulated two priorities: to ensure that Washington was well-defended, and to conduct an aggressive war effort that would satisfy the demand in the North for prompt, decisive victory; major Northern newspaper editors expected victory within 90 days. Twice a week, Lincoln would meet with his cabinet in the afternoon, and occasionally Mary Lincoln would force him to take a carriage ride because she was concerned he was working too hard. Lincoln learned from reading the theoretical book of his chief of staff General Henry Halleck, a disciple of the European strategist Jomini; he began to appreciate the critical need to control strategic points, such as the Mississippi River. Lincoln saw the importance of Vicksburg and understood the necessity of defeating the enemy's army, rather than simply capturing territory. === General McClellan === After the Union rout at Bull Run, the first major battle of the Civil War, and the retirement of the aged Winfield Scott in late 1861, Lincoln appointed Major General George B. McClellan general-in-chief of all the Union armies. McClellan, a young West Point graduate, railroad executive, and Pennsylvania Democrat, took several months to plan and attempt his Peninsula Campaign, longer than Lincoln wanted. The campaign's objective was to capture Richmond by moving the Army of the Potomac by boat to the peninsula and then overland to the Confederate capital. McClellan's repeated delays frustrated Lincoln and Congress, as did his position that no troops were needed to defend Washington. Lincoln insisted on holding some of McClellan's troops in defense of the capital; McClellan, who consistently overestimated the strength of Confederate troops, blamed this decision for the ultimate failure of the Peninsula Campaign. Lincoln removed McClellan as general-in-chief in March 1862, after McClellan's "Harrison's Landing Letter", in which he offered unsolicited political advice to Lincoln urging caution in the war effort. The office remained empty until July, when Henry Halleck was selected for it. McClellan's letter incensed Radical Republicans, who successfully pressured Lincoln to appoint John Pope, a Republican, as head of the new Army of Virginia. Pope complied with Lincoln's strategic desire to move toward Richmond from the north, thus protecting the capital from attack.However, lacking requested reinforcements from McClellan, now commanding the Army of the Potomac, Pope was soundly defeated at the Second Battle of Bull Run in the summer of 1862, forcing the Army of the Potomac to defend Washington for a second time. The war also expanded with naval operations in 1862 when the CSS Virginia, formerly the USS Merrimack, damaged or destroyed three Union vessels in Norfolk, Virginia, before being engaged and damaged by the USS Monitor. Lincoln closely reviewed the dispatches and interrogated naval officers during their clash in the Battle of Hampton Roads.Despite his dissatisfaction with McClellan's failure to reinforce Pope, Lincoln was desperate, and restored him to command of all forces around Washington, to the dismay of all in his cabinet but Seward. Two days after McClellan's return to command, General Robert E. Lee's forces crossed the Potomac River into Maryland, leading to the Battle of Antietam in September 1862. The ensuing Union victory was among the bloodiest in American history, but it enabled Lincoln to announce that he would issue an Emancipation Proclamation in January. Having composed the Proclamation some time earlier, Lincoln had waited for a military victory to publish it to avoid it being perceived as the product of desperation.McClellan then resisted the President's demand that he pursue Lee's retreating and exposed army, while his counterpart General Don Carlos Buell likewise refused orders to move the Army of the Ohio against rebel forces in eastern Tennessee. As a result, Lincoln replaced Buell with William Rosecrans; and, after the 1862 midterm elections, he replaced McClellan with Republican Ambrose Burnside. Both of these replacements were political moderates and prospectively more supportive of the Commander-in-Chief. Burnside, against the advice of the president, prematurely launched an offensive across the Rappahannock River and was stunningly defeated by Lee at Fredericksburg in December. Not only had Burnside been defeated on the battlefield, but his soldiers were disgruntled and undisciplined. Desertions during 1863 were in the thousands and they increased after Fredericksburg. Lincoln brought in Joseph Hooker, despite his record of loose talk about the need for a military dictatorship.The mid-term elections in 1862 brought the Republicans severe losses due to sharp disfavor with the administration over its failure to deliver a speedy end to the war, as well as rising inflation, new high taxes, rumors of corruption, the suspension of habeas corpus, the military draft law, and fears that freed slaves would undermine the labor market. The Emancipation Proclamation announced in September gained votes for the Republicans in the rural areas of New England and the upper Midwest, but it lost votes in the cities and the lower Midwest.While Republicans were discouraged, Democrats were energized and did especially well in Pennsylvania, Ohio, Indiana, and New York. The Republicans did maintain their majorities in Congress and in the major states, except New York. The Cincinnati Gazette contended that the voters were "depressed by the interminable nature of this war, as so far conducted, and by the rapid exhaustion of the national resources without progress".In the spring of 1863, Lincoln was optimistic about upcoming military campaigns to the point of thinking the end of the war could be near if a string of victories could be put together; these plans included attacks by Hooker on Lee north of Richmond, Rosecrans on Chattanooga, Grant on Vicksburg, and a naval assault on Charleston.Hooker was routed by Lee at the Battle of Chancellorsville in May, but continued to command his troops for some weeks. He ignored Lincoln's order to divide his troops, and possibly force Lee to do the same in Harper's Ferry, and tendered his resignation, which Lincoln accepted. He was replaced by George Meade, who followed Lee into Pennsylvania for the Gettysburg Campaign, which was a victory for the Union, though Lee's army avoided capture. At the same time, after initial setbacks, Grant laid siege to Vicksburg and the Union navy attained some success in Charleston harbor. After the Battle of Gettysburg, Lincoln clearly understood that his military decisions would be more effectively carried out by conveying his orders through his War Secretary or his general-in-chief on to his generals, who resented his civilian interference with their own plans. Even so, he often continued to give detailed directions to his generals as Commander-in-Chief. === Emancipation Proclamation === Lincoln understood that the Federal government's power to end slavery was limited by the Constitution, which before 1865, committed the issue to individual states. He argued before and during his election that the eventual extinction of slavery would result from preventing its expansion into new U.S. territory. At the beginning of the war, he also sought to persuade the states to accept compensated emancipation in return for their prohibition of slavery. Lincoln believed that curtailing slavery in these ways would economically expunge it, as envisioned by the Founding Fathers, under the constitution. President Lincoln rejected two geographically limited emancipation attempts by Major General John C. Frémont in August 1861 and by Major General David Hunter in May 1862, on the grounds that it was not within their power, and it would upset the border states loyal to the Union.On June 19, 1862, endorsed by Lincoln, Congress passed an act banning slavery on all federal territory. In July, the Confiscation Act of 1862 was passed, which set up court procedures that could free the slaves of anyone convicted of aiding the rebellion. Although Lincoln believed it was not within Congress's power to free the slaves within the states, he approved the bill in deference to the legislature. He felt such action could only be taken by the Commander-in-Chief using war powers granted to the president by the Constitution, and Lincoln was planning to take that action. In that month, Lincoln discussed a draft of the Emancipation Proclamation with his cabinet. In it, he stated that "as a fit and necessary military measure, on January 1, 1863, all persons held as slaves in the Confederate states will thenceforward, and forever, be free".Privately, Lincoln concluded at this point that the slave base of the Confederacy had to be eliminated. However, Copperheads argued that emancipation was a stumbling block to peace and reunification. Republican editor Horace Greeley of the highly influential New York Tribune fell for the ploy, and Lincoln refuted it directly in a shrewd letter of August 22, 1862. Although he said he personally wished all men could be free, Lincoln stated that the primary goal of his actions as the U.S. president (he used the first person pronoun and explicitly refers to his "official duty") was that of preserving the Union: My paramount object in this struggle is to save the Union, and is not either to save or to destroy slavery. If I could save the Union without freeing any slave I would do it, and if I could save it by freeing all the slaves I would do it; and if I could save it by freeing some and leaving others alone I would also do that. What I do about slavery, and the colored race, I do because I believe it helps to save the Union; and what I forbear, I forbear because I do not believe it would help to save the Union ... [¶] I have here stated my purpose according to my view of official duty; and I intend no modification of my oft-expressed personal wish that all men everywhere could be free. The Emancipation Proclamation, issued on September 22, 1862, and put into effect on January 1, 1863, declared free the slaves in 10 states not then under Union control, with exemptions specified for areas already under Union control in two states. Lincoln spent the next 100 days preparing the army and the nation for emancipation, while Democrats rallied their voters in the 1862 off-year elections by warning of the threat freed slaves posed to northern whites.Once the abolition of slavery in the rebel states became a military objective, as Union armies advanced south, more slaves were liberated until all three million of them in Confederate territory were freed. Lincoln's comment on the signing of the Proclamation was: "I never, in my life, felt more certain that I was doing right, than I do in signing this paper." For some time, Lincoln continued earlier plans to set up colonies for the newly freed slaves. He commented favorably on colonization in the Emancipation Proclamation, but all attempts at such a massive undertaking failed. A few days after Emancipation was announced, 13 Republican governors met at the War Governors' Conference; they supported the president's Proclamation, but suggested the removal of General George B. McClellan as commander of the Union Army.Enlisting former slaves in the military was official government policy after the issuance of the Emancipation Proclamation. By the spring of 1863, Lincoln was ready to recruit black troops in more than token numbers. In a letter to Andrew Johnson, the military governor of Tennessee, encouraging him to lead the way in raising black troops, Lincoln wrote, "The bare sight of 50,000 armed and drilled black soldiers on the banks of the Mississippi would end the rebellion at once". By the end of 1863, at Lincoln's direction, General Lorenzo Thomas had recruited 20 regiments of blacks from the Mississippi Valley. Frederick Douglass once observed of Lincoln: "In his company, I was never reminded of my humble origin, or of my unpopular color". === Gettysburg Address (1863) === With the great Union victory at the Battle of Gettysburg in July 1863, and the defeat of the Copperheads in the Ohio election in the fall, Lincoln maintained a strong base of party support and was in a strong position to redefine the war effort, despite the New York City draft riots. The stage was set for his address at the Gettysburg battlefield cemetery on November 19, 1863. Defying Lincoln's prediction that "the world will little note, nor long remember what we say here", the Address became the most quoted speech in American history.In 272 words, and three minutes, Lincoln asserted the nation was born not in 1789, but in 1776, "conceived in Liberty, and dedicated to the proposition that all men are created equal". He defined the war as an effort dedicated to these principles of liberty and equality for all. The emancipation of slaves was now part of the national war effort. He declared that the deaths of so many brave soldiers would not be in vain, that slavery would end as a result of the losses, and the future of democracy in the world would be assured, that "government of the people, by the people, for the people, shall not perish from the earth". Lincoln concluded that the Civil War had a profound objective: a new birth of freedom in the nation. === General Grant === Meade's failure to capture Lee's army as it retreated from Gettysburg, and the continued passivity of the Army of the Potomac, persuaded Lincoln that a change in command was needed. General Ulysses S. Grant's victories at the Battle of Shiloh and in the Vicksburg campaign impressed Lincoln and made Grant a strong candidate to head the Union Army. Responding to criticism of Grant after Shiloh, Lincoln had said, "I can't spare this man. He fights." With Grant in command, Lincoln felt the Union Army could relentlessly pursue a series of coordinated offensives in multiple theaters, and have a top commander who agreed on the use of black troops.Nevertheless, Lincoln was concerned that Grant might be considering a candidacy for President in 1864, as McClellan was. Lincoln arranged for an intermediary to make inquiry into Grant's political intentions, and being assured that he had none, submitted to the Senate Grant's promotion to commander of the Union Army. He obtained Congress's consent to reinstate for Grant the rank of Lieutenant General, which no officer had held since George Washington.Grant waged his bloody Overland Campaign in 1864. This is often characterized as a war of attrition, given high Union losses at battles such as the Battle of the Wilderness and Cold Harbor. Even though they had the advantage of fighting on the defensive, the Confederate forces had "almost as high a percentage of casualties as the Union forces". The high casualty figures of the Union alarmed the North; Grant had lost a third of his army, and Lincoln asked what Grant's plans were, to which the general replied, "I propose to fight it out on this line if it takes all summer." The Confederacy lacked reinforcements, so Lee's army shrank with every costly battle. Grant's army moved south, crossed the James River, forcing a siege and trench warfare outside Petersburg, Virginia. Lincoln then made an extended visit to Grant's headquarters at City Point, Virginia. This allowed the president to confer in person with Grant and William Tecumseh Sherman about the hostilities, as Sherman coincidentally managed a hasty visit to Grant from his position in North Carolina. Lincoln and the Republican Party mobilized support for the draft throughout the North, and replaced the Union losses.Lincoln authorized Grant to target the Confederate infrastructure—such as plantations, railroads, and bridges—hoping to destroy the South's morale and weaken its economic ability to continue fighting. Grant's move to Petersburg resulted in the obstruction of three railroads between Richmond and the South. This strategy allowed Generals Sherman and Philip Sheridan to destroy plantations and towns in Virginia's Shenandoah Valley. The damage caused by Sherman's March to the Sea through Georgia in 1864 was limited to a 60-mile (97 km) swath, but neither Lincoln nor his commanders saw destruction as the main goal, but rather defeat of the Confederate armies. Mark E. Neely Jr. has argued that there was no effort to engage in "total war" against civilians which he believed did take place during World War II.Confederate general Jubal Early began a series of assaults in the North that threatened the Capital. During Early's raid on Washington, D.C. in 1864, Lincoln was watching the combat from an exposed position; Captain Oliver Wendell Holmes shouted at him, "Get down, you damn fool, before you get shot!" After repeated calls on Grant to defend Washington, Sheridan was appointed and the threat from Early was dispatched.As Grant continued to wear down Lee's forces, efforts to discuss peace began. Confederate Vice President Stephens led a group to meet with Lincoln, Seward, and others at Hampton Roads. Lincoln refused to allow any negotiation with the Confederacy as a coequal; his sole objective was an agreement to end the fighting and the meetings produced no results. On April 1, 1865, Grant successfully outflanked Lee's forces in the Battle of Five Forks and nearly encircled Petersburg, and the Confederate government evacuated Richmond. Days later, when that city fell, Lincoln visited the vanquished Confederate capital; as he walked through the city, white Southerners were stone-faced, but freedmen greeted him as a hero. On April 9, Lee surrendered to Grant at Appomattox and the war was effectively over. === 1864 re-election === While the war was still being waged, Lincoln faced reelection in 1864. Lincoln was a master politician, bringing together—and holding together—all the main factions of the Republican Party, and bringing in War Democrats such as Edwin M. Stanton and Andrew Johnson as well. Lincoln spent many hours a week talking to politicians from across the land and using his patronage powers—greatly expanded over peacetime—to hold the factions of his party together, build support for his own policies, and fend off efforts by Radicals to drop him from the 1864 ticket. At its 1864 convention, the Republican Party selected Johnson, a War Democrat from the Southern state of Tennessee, as his running mate. To broaden his coalition to include War Democrats as well as Republicans, Lincoln ran under the label of the new Union Party.When Grant's 1864 spring campaigns turned into bloody stalemates and Union casualties mounted, the lack of military success wore heavily on the President's re-election prospects, and many Republicans across the country feared that Lincoln would be defeated. Sharing this fear, Lincoln wrote and signed a pledge that, if he should lose the election, he would still defeat the Confederacy before turning over the White House: This morning, as for some days past, it seems exceedingly probable that this Administration will not be re-elected. Then it will be my duty to so co-operate with the President elect, as to save the Union between the election and the inauguration; as he will have secured his election on such ground that he cannot possibly save it afterward. Lincoln did not show the pledge to his cabinet, but asked them to sign the sealed envelope. While the Democratic platform followed the "Peace wing" of the party and called the war a "failure", their candidate, General George B. McClellan, supported the war and repudiated the platform. Lincoln provided Grant with more troops and mobilized his party to renew its support of Grant in the war effort. Sherman's capture of Atlanta in September and David Farragut's capture of Mobile ended defeatist jitters; the Democratic Party was deeply split, with some leaders and most soldiers openly for Lincoln. By contrast, the National Union Party was united and energized as Lincoln made emancipation the central issue, and state Republican parties stressed the perfidy of the Copperheads. On November 8, Lincoln was re-elected in a landslide, carrying all but three states, and receiving 78 percent of the Union soldiers' vote. On March 4, 1865, Lincoln delivered his second inaugural address. In it, he deemed the high casualties on both sides to be God's will. Historian Mark Noll concludes it ranks "among the small handful of semi-sacred texts by which Americans conceive their place in the world". Lincoln said: Fondly do we hope—fervently do we pray—that this mighty scourge of war may speedily pass away. Yet, if God wills that it continue, until all the wealth piled by the bond-man's 250 years of unrequited toil shall be sunk, and until every drop of blood drawn with the lash, shall be paid by another drawn with the sword, as was said 3,000 years ago, so still it must be said, "the judgments of the Lord, are true and righteous altogether". With malice toward none; with charity for all; with firmness in the right, as God gives us to see the right, let us strive on to finish the work we are in; to bind up the nation's wounds; to care for him who shall have borne the battle, and for his widow, and his orphan—to do all which may achieve and cherish a just and lasting peace, among ourselves, and with all nations. === Reconstruction === Reconstruction began during the war, as Lincoln and his associates anticipated questions of how to reintegrate the conquered southern states, and how to determine the fates of Confederate leaders and freed slaves. Shortly after Lee's surrender, a general had asked Lincoln how the defeated Confederates should be treated, and Lincoln replied, "Let 'em up easy." In keeping with that sentiment, Lincoln led the moderates regarding Reconstruction policy, and was opposed by the Radical Republicans, under Rep. Thaddeus Stevens, Sen. Charles Sumner and Sen. Benjamin Wade, political allies of the president on other issues. Determined to find a course that would reunite the nation and not alienate the South, Lincoln urged that speedy elections under generous terms be held throughout the war. His Amnesty Proclamation of December 8, 1863, offered pardons to those who had not held a Confederate civil office, had not mistreated Union prisoners, and would sign an oath of allegiance. As Southern states were subdued, critical decisions had to be made as to their leadership while their administrations were re-formed. Of special importance were Tennessee and Arkansas, where Lincoln appointed Generals Andrew Johnson and Frederick Steele as military governors, respectively. In Louisiana, Lincoln ordered General Nathaniel P. Banks to promote a plan that would restore statehood when 10 percent of the voters agreed to it. Lincoln's Democratic opponents seized on these appointments to accuse him of using the military to ensure his and the Republicans' political aspirations. On the other hand, the Radicals denounced his policy as too lenient, and passed their own plan, the Wade-Davis Bill, in 1864. When Lincoln vetoed the bill, the Radicals retaliated by refusing to seat representatives elected from Louisiana, Arkansas, and Tennessee.Lincoln's appointments were designed to keep both the moderate and Radical factions in harness. To fill Chief Justice Taney's seat on the Supreme Court, he named the choice of the Radicals, Salmon P. Chase, who Lincoln believed would uphold the emancipation and paper money policies.After implementing the Emancipation Proclamation, which did not apply to every state, Lincoln increased pressure on Congress to outlaw slavery throughout the entire nation with a constitutional amendment. Lincoln declared that such an amendment would "clinch the whole matter". By December 1863, a proposed constitutional amendment that would outlaw slavery was brought to Congress for passage. This first attempt at an amendment failed to pass, falling short of the required two-thirds majority on June 15, 1864, in the House of Representatives. Passage of the proposed amendment became part of the Republican/Unionist platform in the election of 1864. After a long debate in the House, a second attempt passed Congress on January 31, 1865, and was sent to the state legislatures for ratification. Upon ratification, it became the Thirteenth Amendment to the United States Constitution on December 6, 1865.As the war drew to a close, Lincoln's presidential Reconstruction for the South was in flux; having believed the federal government had limited responsibility to the millions of freedmen. He signed into law Senator Charles Sumner's Freedmen's Bureau bill that set up a temporary federal agency designed to meet the immediate material needs of former slaves. The law assigned land for a lease of three years with the ability to purchase title for the freedmen. Lincoln stated that his Louisiana plan did not apply to all states under Reconstruction. Shortly before his assassination, Lincoln announced he had a new plan for southern Reconstruction. Discussions with his cabinet revealed Lincoln planned short-term military control over southern states, until readmission under the control of southern Unionists.Historians agree that it is impossible to predict exactly what Lincoln would have done about Reconstruction if he had lived, but they make projections based on his known policy positions and political acumen. Lincoln biographers James G. Randall and Richard Current, according to David Lincove, argue that: It is likely that had he lived, Lincoln would have followed a policy similar to Johnson's, that he would have clashed with congressional Radicals, that he would have produced a better result for the freedmen than occurred, and that his political skills would have helped him avoid Johnson's mistakes. Eric Foner argues that: Unlike Sumner and other Radicals, Lincoln did not see Reconstruction as an opportunity for a sweeping political and social revolution beyond emancipation. He had long made clear his opposition to the confiscation and redistribution of land. He believed, as most Republicans did in April 1865, that the voting requirements should be determined by the states. He assumed that political control in the South would pass to white Unionists, reluctant secessionists, and forward-looking former Confederates. But time and again during the war, Lincoln, after initial opposition, had come to embrace positions first advanced by abolitionists and Radical Republicans. ... Lincoln undoubtedly would have listened carefully to the outcry for further protection for the former slaves ... It is entirely plausible to imagine Lincoln and Congress agreeing on a Reconstruction policy that encompassed federal protection for basic civil rights plus limited black suffrage, along the lines Lincoln proposed just before his death. === Redefining the republic and republicanism === The successful reunification of the states had consequences for the name of the country. The term "the United States" has historically been used, sometimes in the plural ("these United States"), and other times in the singular, without any particular grammatical consistency. The Civil War was a significant force in the eventual dominance of the singular usage by the end of the 19th century.In recent years, historians such as Harry Jaffa, Herman Belz, John Diggins, Vernon Burton and Eric Foner have stressed Lincoln's redefinition of republican values. As early as the 1850s, a time when most political rhetoric focused on the sanctity of the Constitution, Lincoln redirected emphasis to the Declaration of Independence as the foundation of American political values—what he called the "sheet anchor" of republicanism. The Declaration's emphasis on freedom and equality for all, in contrast to the Constitution's tolerance of slavery, shifted the debate. As Diggins concludes regarding the highly influential Cooper Union speech of early 1860, "Lincoln presented Americans a theory of history that offers a profound contribution to the theory and destiny of republicanism itself." His position gained strength because he highlighted the moral basis of republicanism, rather than its legalisms. Nevertheless, in 1861, Lincoln justified the war in terms of legalisms (the Constitution was a contract, and for one party to get out of a contract all the other parties had to agree), and then in terms of the national duty to guarantee a republican form of government in every state. Burton (2008) argues that Lincoln's republicanism was taken up by the Freedmen as they were emancipated.In March 1861, in Lincoln's first inaugural address, he explored the nature of democracy. He denounced secession as anarchy, and explained that majority rule had to be balanced by constitutional restraints in the American system. He said "A majority held in restraint by constitutional checks and limitations, and always changing easily with deliberate changes of popular opinions and sentiments, is the only true sovereign of a free people." === Other enactments === Lincoln adhered to the Whig theory of the presidency, which gave Congress primary responsibility for writing the laws while the Executive enforced them. Lincoln vetoed only four bills passed by Congress; the only important one was the Wade-Davis Bill with its harsh program of Reconstruction. He signed the Homestead Act in 1862, making millions of acres of government-held land in the West available for purchase at very low cost. The Morrill Land-Grant Colleges Act, also signed in 1862, provided government grants for agricultural colleges in each state. The Pacific Railway Acts of 1862 and 1864 granted federal support for the construction of the United States' First Transcontinental Railroad, which was completed in 1869. The passage of the Homestead Act and the Pacific Railway Acts was made possible by the absence of Southern congressmen and senators who had opposed the measures in the 1850s. Other important legislation involved two measures to raise revenues for the Federal government: tariffs (a policy with long precedent), and a new Federal income tax. In 1861, Lincoln signed the second and third Morrill Tariff, the first having become law under James Buchanan. Also in 1861, Lincoln signed the Revenue Act of 1861, creating the first U.S. income tax. This created a flat tax of 3 percent on incomes above $800 ($21,800 in current dollar terms), which was later changed by the Revenue Act of 1862 to a progressive rate structure.Lincoln also presided over the expansion of the federal government's economic influence in several other areas. The creation of the system of national banks by the National Banking Act provided a strong financial network in the country. It also established a national currency. In 1862, Congress created, with Lincoln's approval, the Department of Agriculture. In 1862, Lincoln sent a senior general, John Pope, to put down the "Sioux Uprising" in Minnesota. Presented with 303 execution warrants for convicted Santee Dakota who were accused of killing innocent farmers, Lincoln conducted his own personal review of each of these warrants, eventually approving 39 for execution (one was later reprieved). President Lincoln had planned to reform federal Indian policy.In the wake of Grant's casualties in his campaign against Lee, Lincoln had considered yet another executive call for a military draft, but it was never issued. In response to rumors of one, however, the editors of the New York World and the Journal of Commerce published a false draft proclamation which created an opportunity for the editors and others employed at the publications to corner the gold market. Lincoln's reaction was to send the strongest of messages to the media about such behavior; he ordered the military to seize the two papers. The seizure lasted for two days.Lincoln is largely responsible for the institution of the Thanksgiving holiday in the United States. Before Lincoln's presidency, Thanksgiving, while a regional holiday in New England since the 17th century, had been proclaimed by the federal government only sporadically and on irregular dates. The last such proclamation had been during James Madison's presidency 50 years before. In 1863, Lincoln declared the final Thursday in November of that year to be a day of Thanksgiving. In June 1864, Lincoln approved the Yosemite Grant enacted by Congress, which provided unprecedented federal protection for the area now known as Yosemite National Park. === Judicial appointments === ==== Supreme Court appointments ==== Noah Haynes Swayne – 1862 Samuel Freeman Miller – 1862 David Davis – 1862 Stephen Johnson Field – 1863 Salmon Portland Chase – 1864 (Chief Justice) Lincoln's declared philosophy on court nominations was that "we cannot ask a man what he will do, and if we should, and he should answer us, we should despise him for it. Therefore we must take a man whose opinions are known." Lincoln made five appointments to the United States Supreme Court. Noah Haynes Swayne, nominated January 21, 1862, and appointed January 24, 1862, was chosen as an anti-slavery lawyer who was committed to the Union. Samuel Freeman Miller, nominated and appointed on July 16, 1862, supported Lincoln in the 1860 election and was an avowed abolitionist. David Davis, Lincoln's campaign manager in 1860, nominated December 1, 1862, and appointed December 8, 1862, had also served as a judge in Lincoln's Illinois court circuit. Stephen Johnson Field, a previous California Supreme Court justice, was nominated March 6, 1863, and appointed March 10, 1863, and provided geographic balance, as well as political balance to the court as a Democrat. Finally, Lincoln's Treasury Secretary, Salmon P. Chase, was nominated as Chief Justice, and appointed the same day, on December 6, 1864. Lincoln believed Chase was an able jurist, would support Reconstruction legislation, and that his appointment united the Republican Party. ==== Other judicial appointments ==== Lincoln appointed 32 federal judges, including four Associate Justices and one Chief Justice to the Supreme Court of the United States, and 27 judges to the United States district courts. Lincoln appointed no judges to the United States circuit courts during his time in office. === States admitted to the Union === West Virginia, admitted to the Union June 20, 1863, contained the former north-westernmost counties of Virginia that seceded from Virginia after that commonwealth declared its secession from the Union. As a condition for its admission, West Virginia's constitution was required to provide for the gradual abolition of slavery. Nevada, which became the third State in the far-west of the continent, was admitted as a free state on October 31, 1864. == Assassination and funeral == Abraham Lincoln was assassinated by John Wilkes Booth on Good Friday, April 14, 1865, while attending a play at Ford's Theatre as the American Civil War was drawing to a close. The assassination occurred five days after the surrender of Robert E. Lee and the Confederate Army of Northern Virginia. Booth was a well-known actor and a Confederate spy from Maryland; though he never joined the Confederate army, he had contacts with the Confederate secret service. In 1864, Booth formulated a plan (very similar to one of Thomas N. Conrad previously authorized by the Confederacy) to kidnap Lincoln in exchange for the release of Confederate prisoners. After attending an April 11, 1865, speech in which Lincoln promoted voting rights for blacks, an incensed Booth changed his plans and became determined to assassinate the president. Learning that the President and Grant would be attending Ford's Theatre, Booth formulated a plan with co-conspirators to assassinate Lincoln and Grant at the theater, as well as Vice President Johnson and Secretary of State Seward at their homes. Without his main bodyguard, Ward Hill Lamon, Lincoln left to attend the play Our American Cousin on April 14. At the last minute, Grant decided to go to New Jersey to visit his children instead of attending the play.Lincoln's bodyguard, John Parker, left Ford's Theater during intermission to drink at the saloon next door. The now unguarded President sat in his state box in the balcony. Seizing the opportunity, Booth crept up from behind and at about 10:13 pm, aimed at the back of Lincoln's head and fired at point-blank range, mortally wounding the President. Major Henry Rathbone momentarily grappled with Booth, but Booth stabbed him and escaped.After being on the run for 12 days, Booth was tracked down and found on a farm in Virginia, some 70 miles (110 km) south of Washington. After refusing to surrender to Union troops, Booth was killed by Sergeant Boston Corbett on April 26.Doctor Charles Leale, an Army surgeon, found the President unresponsive, barely breathing and with no detectable pulse. Having determined that the President had been shot in the head, and not stabbed in the shoulder as originally thought, he made an attempt to clear the blood clot, after which the President began to breathe more naturally. The dying President was taken across the street to Petersen House. After remaining in a coma for nine hours, Lincoln died at 7:22 am on April 15. According to eyewitnesses, he face was fixed in a smile when he expired. Secretary of War Stanton saluted and said, "Now he belongs to the ages."Lincoln's flag-enfolded body was then escorted in the rain to the White House by bareheaded Union officers, while the city's church bells rang. President Johnson was sworn in at 10:00 am, less than 3 hours after Lincoln's death. The late President lay in state in the East Room, and then in the Capitol Rotunda from April 19 through April 21. For his final journey with his son Willie, both caskets were transported in the executive coach "United States" and for three weeks the Lincoln Special funeral train decorated in black bunting bore Lincoln's remains on a slow circuitous waypoint journey from Washington D.C. to Springfield, Illinois, stopping at many cities across the North for large-scale memorials attended by hundreds of thousands, as well as many people who gathered in informal trackside tributes with bands, bonfires, and hymn singing or silent reverence with hat in hand as the railway procession slowly passed by. Poet Walt Whitman composed When Lilacs Last in the Dooryard Bloom'd to eulogize Lincoln, one of four poems he wrote about the assassinated president. Historians have emphasized the widespread shock and sorrow, but also noted that some Lincoln haters cheered when they heard the news. African-Americans were especially moved; they had lost 'their Moses'. In a larger sense, the outpouring of grief and anguish was in response to the deaths of so many men in the war that had just ended. == Religious and philosophical beliefs == As a young man, Lincoln was a religious skeptic, or, in the words of a biographer, an iconoclast. Later in life, Lincoln's frequent use of religious imagery and language might have reflected his own personal beliefs or might have been a device to appeal to his audiences, who were mostly evangelical Protestants. He never joined a church, although he frequently attended with his wife. However, he was deeply familiar with the Bible, and he both quoted and praised it. He was private about his beliefs and respected the beliefs of others. Lincoln never made a clear profession of Christian beliefs. However, he did believe in an all-powerful God that shaped events and, by 1865, was expressing those beliefs in major speeches.In the 1840s, Lincoln subscribed to the Doctrine of Necessity, a belief that asserted the human mind was controlled by some higher power. In the 1850s, Lincoln believed in "providence" in a general way, and rarely used the language or imagery of the evangelicals; he regarded the republicanism of the Founding Fathers with an almost religious reverence. When he suffered the death of his son Edward, Lincoln more frequently expressed a need to depend on God. The death of his son Willie in February 1862 may have caused Lincoln to look toward religion for answers and solace. After Willie's death, Lincoln considered why, from a divine standpoint, the severity of the war was necessary. He wrote at this time that God "could have either saved or destroyed the Union without a human contest. Yet the contest began. And having begun, He could give the final victory to either side any day. Yet the contest proceeds." On the day Lincoln was assassinated, he reportedly told his wife he desired to visit the Holy Land. == Health == Several claims abound that Lincoln's health was declining before the assassination. These are often based on photographs appearing to show weight loss and muscle wasting. One such claim is that he suffered from a rare genetic disorder, MEN2b, which manifests with a medullary thyroid carcinoma, mucosal neuromas and a Marfanoid appearance. Others simply claim he had Marfan syndrome, based on his tall appearance with spindly fingers, and the association of possible aortic regurgitation, which can cause bobbing of the head (DeMusset's sign) – based on blurring of Lincoln's head in photographs, which back then had a long exposure time. As of 2009, DNA analysis was being refused by the Grand Army of the Republic museum in Philadelphia. == Historical reputation == In surveys of U.S. scholars ranking presidents conducted since the 1940s, Lincoln is consistently ranked in the top three, often as number one. A 2004 study found that scholars in the fields of history and politics ranked Lincoln number one, while legal scholars placed him second after Washington. In presidential ranking polls conducted in the United States since 1948, Lincoln has been rated at the very top in the majority of polls. Generally, the top three presidents are rated as 1. Lincoln; 2. George Washington; and 3. Franklin D. Roosevelt, although Lincoln and Washington, and Washington and Roosevelt, are occasionally reversed.President Lincoln's assassination increased his status to the point of making him a national martyr. Lincoln was viewed by abolitionists as a champion for human liberty. Republicans linked Lincoln's name to their party. Many, though not all, in the South considered Lincoln as a man of outstanding ability. Historians have said he was "a classical liberal" in the 19th century sense. Allen C. Guelzo states that Lincoln was a classical liberal democrat—an enemy of artificial hierarchy, a friend to trade and business as ennobling and enabling, and an American counterpart to Mill, Cobden, and Bright (whose portrait Lincoln hung in his White House office). Lincoln became a favorite exemplar for liberal intellectuals across Europe and Latin America and even in Asia.Schwartz argues that Lincoln's American reputation grew slowly in the late 19th century until the Progressive Era (1900–1920s) when he emerged as one of the most venerated heroes in American history, with even white Southerners in agreement. The high point came in 1922 with the dedication of the Lincoln Memorial on the National Mall in Washington, D.C. In the New Deal era liberals honored Lincoln not so much as the self-made man or the great war president, but as the advocate of the common man who they believe would have supported the welfare state. In the Cold War years, Lincoln's image shifted to emphasize the symbol of freedom who brought hope to those oppressed by communist regimes.By the 1970s Lincoln had become a hero to political conservatives for his intense nationalism, support for business, his insistence on stopping the spread of human bondage, his acting in terms of Lockean and Burkean principles on behalf of both liberty and tradition, and his devotion to the principles of the Founding Fathers. As a Whig activist, Lincoln was a spokesman for business interests, favoring high tariffs, banks, internal improvements, and railroads in opposition to the agrarian Democrats. William C. Harris found that Lincoln's "reverence for the Founding Fathers, the Constitution, the laws under it, and the preservation of the Republic and its institutions undergirded and strengthened his conservatism". James G. Randall emphasizes his tolerance and especially his moderation "in his preference for orderly progress, his distrust of dangerous agitation, and his reluctance toward ill digested schemes of reform". Randall concludes that, "he was conservative in his complete avoidance of that type of so-called 'radicalism' which involved abuse of the South, hatred for the slaveholder, thirst for vengeance, partisan plotting, and ungenerous demands that Southern institutions be transformed overnight by outsiders."By the late 1960s, some African American intellectuals led by Lerone Bennett Jr., rejected Lincoln's role as the Great Emancipator. Bennett won wide attention when he called Lincoln a white supremacist in 1968. He noted that Lincoln used ethnic slurs and told jokes that ridiculed blacks. Bennett argued that Lincoln opposed social equality, and proposed sending freed slaves to another country. Defenders, such as authors Dirck and Cashin, retorted that he was not as bad as most politicians of his day; and that he was a "moral visionary" who deftly advanced the abolitionist cause, as fast as politically possible. The emphasis shifted away from Lincoln-the-emancipator to an argument that blacks had freed themselves from slavery, or at least were responsible for pressuring the government on emancipation. Historian Barry Schwartz wrote in 2009 that Lincoln's image suffered "erosion, fading prestige, benign ridicule" in the late 20th century. On the other hand, Donald opined in his 1996 biography that Lincoln was distinctly endowed with the personality trait of negative capability, defined by the poet John Keats and attributed to extraordinary leaders who were "content in the midst of uncertainties and doubts, and not compelled toward fact or reason". In the 21st century, President Barack Obama named Lincoln his favorite president and insisted on using Lincoln's Bible for his swearing in to office at both his inaugurations.Lincoln has often been portrayed by Hollywood, almost always in a flattering light.The Union nationalism as envisioned by Lincoln, "helped lead America to the nationalism of Theodore Roosevelt, Woodrow Wilson, and Franklin Delano Roosevelt." == Memory and memorials == Lincoln's portrait appears on two denominations of United States currency, the penny and the $5 bill. His likeness also appears on many postage stamps and he has been memorialized in many town, city, and county names, including the capital of Nebraska. While he is usually portrayed bearded, he first grew a beard in 1860 at the suggestion of 11-year-old Grace Bedell. The most famous and most visited memorials are Lincoln's sculpture on Mount Rushmore; Lincoln Memorial, Ford's Theatre, and Petersen House (where he died) in Washington, D.C.; and the Abraham Lincoln Presidential Library and Museum in Springfield, Illinois, not far from Lincoln's home, as well as his tomb.There was also the Great Moments with Mr. Lincoln exhibit in Disneyland, and Hall of Presidents at Walt Disney World, which had to do with Walt Disney admiring Lincoln ever since he was a little boy. Barry Schwartz, a sociologist who has examined America's cultural memory, argues that in the 1930s and 1940s, the memory of Abraham Lincoln was practically sacred and provided the nation with "a moral symbol inspiring and guiding American life". During the Great Depression, he argues, Lincoln served "as a means for seeing the world's disappointments, for making its sufferings not so much explicable as meaningful". Franklin D. Roosevelt, preparing America for war, used the words of the Civil War president to clarify the threat posed by Germany and Japan. Americans asked, "What would Lincoln do?" However, Schwartz also finds that since World War II, Lincoln's symbolic power has lost relevance, and this "fading hero is symptomatic of fading confidence in national greatness". He suggested that postmodernism and multiculturalism have diluted greatness as a concept.The United States Navy Nimitz-class aircraft carrier USS Abraham Lincoln (CVN-72) is named after Lincoln, the second Navy ship to bear his name. == See also == Outline of Abraham Lincoln Sexuality of Abraham Lincoln Dakota War of 1862 Grace Bedell Lincoln Tower List of photographs of Abraham Lincoln List of civil rights leaders == References == == Bibliography == === Historiography === Barr, John M.

### Instruction: retrieve labels for this: The Academy Awards, also known as the Oscars, are a set of 24 awards for artistic and technical merit in the American film industry, given annually by the Academy of Motion Picture Arts and Sciences (AMPAS), to recognize excellence in cinematic achievements as assessed by the Academy's voting membership. The various category winners are awarded a copy of a golden statuette, officially called the "Academy Award of Merit", which has become commonly known by its nickname "Oscar". The sculpture was created by George Stanley. The awards, first presented in 1929 at the Hollywood Roosevelt Hotel, are overseen by AMPAS.The awards ceremony was first broadcast on radio in 1930 and televised for the first time in 1953. It is now seen live in more than 200 countries and can be streamed live online. The Academy Awards ceremony is the oldest worldwide entertainment awards ceremony. Its equivalents – the Emmy Awards for television, the Tony Awards for theater, and the Grammy Awards for music – are modeled after the Academy Awards.The 90th Academy Awards ceremony, honoring the best films of 2017, was held on 4 March 2018, at the Dolby Theatre, in Los Angeles, California. The ceremony was hosted by Jimmy Kimmel and was broadcast on ABC. A total of 3,072 Oscars have been awarded from the inception of the award through the 90th. == History == The first Academy Awards presentation was held on 16 May 1929, at a private dinner function at the Hollywood Roosevelt Hotel with an audience of about 270 people. The post-awards party was held at the Mayfair Hotel. The cost of guest tickets for that night's ceremony was $5 ($71 in 2017 dollars). Fifteen statuettes were awarded, honoring artists, directors and other participants in the film-making industry of the time, for their works during the 1927–28 period. The ceremony ran for 15 minutes. Winners were announced to media three months earlier. That was changed for the second ceremony in 1930. Since then, for the rest of the first decade, the results were given to newspapers for publication at 11:00 pm on the night of the awards. This method was used until an occasion when the Los Angeles Times announced the winners before the ceremony began; as a result, the Academy has, since 1941, used a sealed envelope to reveal the name of the winners. === Institutions === The first Best Actor awarded was Emil Jannings, for his performances in The Last Command and The Way of All Flesh. He had to return to Europe before the ceremony, so the Academy agreed to give him the prize earlier; this made him the first Academy Award winner in history. At that time, the winners were recognized for all of their work done in a certain category during the qualifying period; for example, Jannings received the award for two movies in which he starred during that period, and Janet Gaynor later won a single Oscar for performances in three films. With the fourth ceremony, however, the system changed, and professionals were honored for a specific performance in a single film. For the first six ceremonies, the eligibility period spanned two calendar years.At the 29th ceremony, held on 27 March 1957, the Best Foreign Language Film category was introduced. Until then, foreign-language films had been honored with the Special Achievement Award. The 74th Academy Awards, held in 2002, presented the first Academy Award for Best Animated Feature.Since 1973, all Academy Awards ceremonies have ended with the Academy Award for Best Picture. Traditionally, the previous year's winner for Best Actor and Best Supporting Actor present the awards for Best Actress and Best Supporting Actress, while the previous year's winner for Best Actress and Best Supporting Actress present the awards for Best Actor and Best Supporting Actor. == Oscar statuette == === Other awards presented by the Academy === See also § Special categories (below).In addition to the Academy Award of Merit (Oscar award), there are nine honorary (non-competitive) awards presented by the Academy from time to time (except for the Academy Honorary Award, the Technical Achievement Award, and the Student Academy Awards, which are presented annually): Governors Awards: The Academy Honorary Award (annual) (which may or may not be in the form of an Oscar statuette); The Irving G. Thalberg Memorial Award (since 1938) (in the form of a bust of Thalberg); The Jean Hersholt Humanitarian Award (since 1957) (in the form of an Oscar statuette); The Academy Scientific and Technical Awards: Academy Award of Merit (non-competitive) (in the form of an Oscar statuette); Scientific and Engineering Award (in the form of a bronze tablet); Technical Achievement Award (annual) (in the form of a certificate); The John A. Bonner Medal of Commendation (since 1978) (in the form of a medal); The Gordon E. Sawyer Award (since 1982); and The Academy Student Academy Awards (annual).The Academy also awards Nicholl Fellowships in Screenwriting. === Academy Award of Merit (Oscar statuette) === See also § Awards of Merit categories (below)The best known award is the Academy Award of Merit, more popularly known as the Oscar statuette. Made of gold-plated bronze on a black metal base, it is 13.5 in (34.3 cm) tall, weighs 8.5 lb (3.856 kg), and depicts a knight rendered in Art Deco style holding a crusader's sword standing on a reel of film with five spokes. The five spokes represent the original branches of the Academy: Actors, Writers, Directors, Producers, and Technicians.The model for the statuette is said to be Mexican actor Emilio "El Indio" Fernández. Sculptor George Stanley (who also did the Muse Fountain at the Hollywood Bowl) sculpted Cedric Gibbons' design. The statuettes presented at the initial ceremonies were gold-plated solid bronze. Within a few years the bronze was abandoned in favor of Britannia metal, a pewter-like alloy which is then plated in copper, nickel silver, and finally, 24-karat gold. Due to a metal shortage during World War II, Oscars were made of painted plaster for three years. Following the war, the Academy invited recipients to redeem the plaster figures for gold-plated metal ones. The only addition to the Oscar since it was created is a minor streamlining of the base. The original Oscar mold was cast in 1928 at the C.W. Shumway & Sons Foundry in Batavia, Illinois, which also contributed to casting the molds for the Vince Lombardi Trophy and Emmy Award's statuettes. From 1983 to 2015, approximately 50 Oscars in a tin alloy with gold plating were made each year in Chicago by Illinois manufacturer R.S. Owens & Company. It takes between three and four weeks to manufacture 50 statuettes. In 2016, the Academy returned to bronze as the core metal of the statuettes, handing manufacturing duties to Walden, New York-based Polich Tallix Fine Art Foundry. While based on a digital scan of an original 1929 Oscar, the statuettes retain their modern-era dimensions and black pedestal. Cast in liquid bronze from 3D-printed ceramic molds and polished, they are then electroplated in 24-karat gold by Brooklyn, New York–based Epner Technology. The time required to produce 50 such statuettes is roughly three months. R.S. Owens is expected to continue producing other awards for the Academy and service existing Oscars that need replating. === Naming === The origin of the name Oscar is disputed. One biography of Bette Davis, who was a president of the Academy, claims she named the Oscar after her first husband, band leader Harmon Oscar Nelson. Another claimed origin is the Academy's Executive Secretary, Margaret Herrick, first saw the award in 1931 and made reference to the statuette's reminding her of her "Uncle Oscar" (a nickname for her cousin Oscar Pierce). Columnist Sidney Skolsky was present during Herrick's naming and seized the name in his byline, "Employees have affectionately dubbed their famous statuette 'Oscar'." One of the earliest mentions of the term Oscar dates to a Time magazine article about the 1934 6th Academy Awards. Walt Disney also thanked the Academy for his Oscar as early as 1932. The trophy officially received the name "Oscar" in 1939 by the Academy of Motion Picture Arts and Sciences. === Engraving === To prevent information identifying the Oscar winners from leaking ahead of the ceremony, Oscar statuettes presented at the ceremony have blank baseplates. Until 2010, winners returned their statuettes to the Academy, and had to wait several weeks to have their names inscribed on their respective Oscars. Since 2010, winners have had the option of having engraved nameplates applied to their statuettes at an inscription-processing station at the Governor's Ball, a party held immediately after the Oscar ceremony. The R.S. Owens company has engraved nameplates made before the ceremony, bearing the name of every potential winner. The nameplates for the non-winning nominees are later recycled. === Ownership of Oscar statuettes === Since 1950, the statuettes have been legally encumbered by the requirement that neither winners nor their heirs may sell the statuettes without first offering to sell them back to the Academy for US$1. If a winner refuses to agree to this stipulation, then the Academy keeps the statuette. Academy Awards not protected by this agreement have been sold in public auctions and private deals for six-figure sums. In December 2011, Orson Welles' 1941 Oscar for Citizen Kane (Academy Award for Best Original Screenplay) was put up for auction, after his heirs won a 2004 court decision contending that Welles did not sign any agreement to return the statue to the Academy. On 20 December 2011, it sold in an online auction for US$861,542.In 1992, Harold Russell needed money for his wife's medical expenses. In a controversial decision, he consigned his 1946 Oscar for Best Supporting Actor for The Best Years of Our Lives to Herman Darvick Autograph Auctions, and on 6 August 1992, in New York City, the Oscar sold to a private collector for $60,500. Since he won the award before 1950, he was not required to offer it to the Academy first. Russell defended his decision, saying, "I don't know why anybody would be critical. My wife's health is much more important than sentimental reasons. The movie will be here, even if Oscar isn't." Harold Russell is the only Academy Award-winning actor to ever sell an Oscar.While the Oscar is owned by the recipient, it is essentially not on the open market. Michael Todd's grandson tried to sell Todd's Oscar statuette to a movie prop collector in 1989, but the Academy won the legal battle by getting a permanent injunction. Although some Oscar sales transactions have been successful, some buyers have subsequently returned the statuettes to the Academy, which keeps them in its treasury. == Nomination == Since 2004, Academy Award nomination results have been announced to the public in mid-January. Prior to that, the results were announced in early February. === Voters === The Academy of Motion Picture Arts and Sciences (AMPAS), a professional honorary organization, maintains a voting membership of over 8,000 as of 2018.Academy membership is divided into different branches, with each representing a different discipline in film production. Actors constitute the largest voting bloc, numbering 1,311 members (22 percent) of the Academy's composition. Votes have been certified by the auditing firm PricewaterhouseCoopers (and its predecessor Price Waterhouse) for the past 83 annual awards ceremonies. The firm mails the ballots of eligible nominees to members of the Academy in December to reflect the previous eligible year with a due date sometime in January of the next year, then tabulates the votes in a process that takes thousands of hours. All AMPAS members must be invited to join by the Board of Governors, on behalf of Academy Branch Executive Committees. Membership eligibility may be achieved by a competitive nomination or a member may submit a name based on other significant contributions to the field of motion pictures. New membership proposals are considered annually. The Academy does not publicly disclose its membership, although as recently as 2007 press releases have announced the names of those who have been invited to join. The 2007 release also stated that it has just under 6,000 voting members. While the membership had been growing, stricter policies have kept its size steady since then.In 2012, the results of a study conducted by the Los Angeles Times were published describing the demographic breakdown of approximately 88% of AMPAS' voting membership. Of the 5,100+ active voters confirmed, 94% were Caucasian, 77% were male, and 54% were found to be over the age of 60. 33% of voting members are former nominees (14%) and winners (19%).In May 2011, the Academy sent a letter advising its 6,000 or so voting members that an online system for Oscar voting would be implemented in 2013. === Rules === According to Rules 2 and 3 of the official Academy Awards Rules, a film must open in the previous calendar year, from midnight at the start of 1 January to midnight at the end of 31 December, in Los Angeles County, California, and play for seven consecutive days, to qualify (except for the Best Foreign Language Film, Best Documentary Feature, and Best Documentary Short Subject).The Best Foreign Language Film award does not require a U.S. release. The Best Documentary Feature award requires week-long releases in both Los Angeles County and New York City during the previous calendar year.The Best Documentary Short Subject award has noticeably different eligibility rules from most other competitive awards. First, the qualifying period for release does not coincide with a calendar year, instead covering a one-year period starting on 1 September and ending on 31 August of the calendar year before the ceremony. Second, there are multiple methods of qualification. The main method is a week-long theatrical release in either Los Angeles County or New York City during the eligibility period. Films also can qualify by winning specified awards at one of a number of competitive film festivals designated by the Academy. Finally, a film that is selected as a gold, silver, or bronze medal winner in the Documentary category of the immediately previous Student Academy Awards is also eligible.For example, the 2009 Best Picture winner, The Hurt Locker, was actually first released in 2008, but did not qualify for the 2008 awards as it did not play its Oscar-qualifying run in Los Angeles until mid-2009, thus qualifying for the 2009 awards. Foreign films must include English subtitles, and each country can submit only one film per year.Rule 2 states that a film must be feature-length, defined as a minimum of 40 minutes, except for short-subject awards, and it must exist either on a 35 mm or 70 mm film print or in 24 frame/s or 48 frame/s progressive scan digital cinema format with a minimum projector resolution of 2048 by 1080 pixels. Effective with the 90th Academy Awards, presented in 2018, multi-part and limited series will be ineligible for the Best Documentary Feature award. This followed the win of O.J.: Made in America, an eight-hour presentation that was screened in a limited release before being broadcast in five parts on ABC and ESPN, in that category in 2017. The Academy's announcement of the new rule made no direct mention of that film.Producers must submit an Official Screen Credits online form before the deadline; in case it is not submitted by the defined deadline, the film will be ineligible for Academy Awards in any year. The form includes the production credits for all related categories. Then, each form is checked and put in a Reminder List of Eligible Releases. In late December ballots and copies of the Reminder List of Eligible Releases are mailed to around 6,000 active members. For most categories, members from each of the branches vote to determine the nominees only in their respective categories (i.e. only directors vote for directors, writers for writers, actors for actors, etc.). In the special case of Best Picture, all voting members are eligible to select the nominees. In all major categories, a variant of the single transferable vote is used, with each member casting a ballot with up to five nominees (ten for Best Picture) ranked preferentially. In certain categories, including Foreign Film, Documentary and Animated Feature Film, nominees are selected by special screening committees made up of members from all branches. In most categories the winner is selected from among the nominees by plurality voting of all members. Since 2009, the Best Picture winner has been chosen by instant runoff voting. Since 2013, re-weighted range voting has been used to select the nominees for the Best Visual Effects.Film companies will spend as much as several million dollars on marketing to awards voters for a movie in the running for Best Picture, in attempts to improve chances of receiving Oscars and other movie awards conferred in Oscar season. The Academy enforces rules to limit overt campaigning by its members so as to try to eliminate excesses and prevent the process from becoming undignified. It has an awards czar on staff who advises members on allowed practices and levies penalties on offenders. For example, a producer of the 2009 Best Picture nominee The Hurt Locker was disqualified as a producer in the category when he contacted associates urging them to vote for his film and not another that was seen as the front-runner (The Hurt Locker eventually won). == Awards ceremonies == === Telecast === The major awards are presented at a live televised ceremony, commonly in late February or early March following the relevant calendar year, and six weeks after the announcement of the nominees. It is the culmination of the film awards season, which usually begins during November or December of the previous year. This is an elaborate extravaganza, with the invited guests walking up the red carpet in the creations of the most prominent fashion designers of the day. Black tie dress is the most common outfit for men, although fashion may dictate not wearing a bow-tie, and musical performers sometimes do not adhere to this. (The artists who recorded the nominees for Best Original Song quite often perform those songs live at the awards ceremony, and the fact that they are performing is often used to promote the television broadcast.) The Academy Awards is the only awards show televised live in the United States (excluding Hawaii), Canada, and the United Kingdom, and gathers millions of viewers elsewhere throughout the world. The Oscars were first televised in 1953 by NBC, which continued to broadcast the event until 1960, when ABC took over, televising the festivities (including the first color broadcast of the event in 1966) through 1970. NBC regained the rights for five years (1971–75), then ABC resumed broadcast duties in 1976 and its current contract with the Academy runs through 2028. The Academy has also produced condensed versions of the ceremony for broadcast in international markets (especially those outside of the Americas) in more desirable local timeslots. The ceremony was broadcast live internationally for the first time via satellite since 1970, but only two South American countries, Chile and Brazil, purchased the rights to air the broadcast. By that time, the television rights to the Academy Awards had been sold in 50 countries. A decade later, the rights were already being sold to 60 countries, and by 1984, the TV rights to the Awards were licensed in 76 countries. The ceremonies were moved up from late March/early April to late February since 2004 to help disrupt and shorten the intense lobbying and ad campaigns associated with Oscar season in the film industry. Another reason was because of the growing TV ratings success coinciding with the NCAA Basketball Tournament, which would cut into the Academy Awards audience. (In 1976 and 1977, ABC's regained Oscars were moved from Tuesday to Monday and went directly opposite NBC's NCAA title game.) The earlier date is also to the advantage of ABC, as it now usually occurs during the highly profitable and important February sweeps period. Some years, the ceremony is moved into first Sunday of March in order to avoid clash with the Winter Olympic Games. Another reason for the move to late February and early March is also to avoid the awards ceremony occurring so close to the religious holidays of Passover and Easter, which for decades had been a grievance from members and the general public. Advertising is somewhat restricted, however, as traditionally no movie studios or competitors of official Academy Award sponsors may advertise during the telecast. The production of the Academy Awards telecast currently holds the distinction of winning the most Emmys in history, with 47 wins and 195 nominations overall since that award's own launch in 1949.After many years of being held on Mondays at 9:00 pm Eastern/6:00 p.m Pacific, since the 1999 ceremonies, it was moved to Sundays at 8:30 pm ET/5:30 pm PT. The reasons given for the move were that more viewers would tune in on Sundays, that Los Angeles rush-hour traffic jams could be avoided, and an earlier start time would allow viewers on the East Coast to go to bed earlier. For many years the film industry opposed a Sunday broadcast because it would cut into the weekend box office. In 2010, the Academy contemplated moving the ceremony even further back into January, citing TV viewers' fatigue with the film industry's long awards season. However, such an accelerated schedule would dramatically decrease the voting period for its members, to the point where some voters would only have time to view the contending films streamed on their computers (as opposed to traditionally receiving the films and ballots in the mail). Furthermore, a January ceremony on Sunday would clash with National Football League playoff games.Originally scheduled for 8 April 1968, the 40th Academy Awards ceremony was postponed for two days, because of the assassination of Dr. Martin Luther King, Jr.. On 30 March 1981, the 53rd Academy Awards was postponed for one day, after the shooting of President Ronald Reagan and others in Washington, D.C. In 1993, an In Memoriam segment was introduced, honoring those who had made a significant contribution to cinema who had died in the preceding 12 months, a selection compiled by a small committee of Academy members. This segment has drawn criticism over the years for the omission of some names. Criticism was also levied for many years regarding another aspect, with the segment having a "popularity contest" feel as the audience varied their applause to those who had died by the subject's cultural impact; the applause has since been muted during the telecast, and the audience is discouraged from clapping during the segment and giving silent reflection instead. In terms of broadcast length, the ceremony generally averages three and a half hours. The first Oscars, in 1929, lasted 15 minutes. At the other end of the spectrum, the 2002 ceremony lasted four hours and twenty-three minutes. In 2010, the organizers of the Academy Awards announced winners' acceptance speeches must not run past 45 seconds. This, according to organizer Bill Mechanic, was to ensure the elimination of what he termed "the single most hated thing on the show" – overly long and embarrassing displays of emotion. In 2016, in a further effort to streamline speeches, winners' dedications were displayed on an on-screen ticker. During the 2018 ceremony, host Jimmy Kimmel acknowledged how long the ceremony had become, by announcing that he would give a brand-new jet ski to whoever gave the shortest speech of the night (a reward won by Mark Bridges when accepting his Best Costume Design award for Phantom Thread).Although still dominant in ratings, the viewership of the Academy Awards have steadily dropped; the 88th Academy Awards were the lowest-rated in the past eight years (although with increases in male and 18-49 viewership), while the show itself also faced mixed reception. Following the show, Variety reported that ABC was, in negotiating an extension to its contract to broadcast the Oscars, seeking to have more creative control over the broadcast itself. Currently and nominally, AMPAS is responsible for most aspects of the telecast, including the choice of production staff and hosting, although ABC is allowed to have some input on their decisions. In August 2016, AMPAS extended its contract with ABC through 2028: the contract neither contains any notable changes, nor gives ABC any further creative control over the telecast. === TV ratings === Historically, the "Oscarcast" has pulled in a bigger haul when box-office hits are favored to win the Best Picture trophy. More than 57.25 million viewers tuned to the telecast for the 70th Academy Awards in 1998, the year of Titanic, which generated close to US$600 million at the North American box office pre-Oscars. The 76th Academy Awards ceremony in which The Lord of the Rings: The Return of the King (pre-telecast box office earnings of US$368 million) received 11 Awards including Best Picture drew 43.56 million viewers. The most watched ceremony based on Nielsen ratings to date, however, was the 42nd Academy Awards (Best Picture Midnight Cowboy) which drew a 43.4% household rating on 7 April 1970.By contrast, ceremonies honoring films that have not performed well at the box office tend to show weaker ratings. The 78th Academy Awards which awarded low-budgeted, independent film Crash (with a pre-Oscar gross of US$53.4 million) generated an audience of 38.64 million with a household rating of 22.91%. In 2008, the 80th Academy Awards telecast was watched by 31.76 million viewers on average with an 18.66% household rating, the lowest rated and least watched ceremony at the time, in spite of celebrating 80 years of the Academy Awards. The Best Picture winner of that particular ceremony was another independently financed film (No Country for Old Men). == Venues == In 1929, the first Academy Awards were presented at a banquet dinner at the Hollywood Roosevelt Hotel. From 1930 to 1943, the ceremony alternated between two venues: the Ambassador Hotel on Wilshire Boulevard and the Biltmore Hotel in downtown Los Angeles. Grauman's Chinese Theatre in Hollywood then hosted the awards from 1944 to 1946, followed by the Shrine Auditorium in Los Angeles from 1947 to 1948. The 21st Academy Awards in 1949 were held at the Academy Award Theatre at what was the Academy's headquarters on Melrose Avenue in Hollywood.From 1950 to 1960, the awards were presented at Hollywood's Pantages Theatre. With the advent of television, the awards from 1953 to 1957 took place simultaneously in Hollywood and New York, first at the NBC International Theatre (1953) and then at the NBC Century Theatre, after which the ceremony took place solely in Los Angeles. The Oscars moved to the Santa Monica Civic Auditorium in Santa Monica, California in 1961. By 1969, the Academy decided to move the ceremonies back to Los Angeles, this time to the Dorothy Chandler Pavilion at the Los Angeles County Music Center. In 2002, the Dolby Theatre (previously known as the Kodak Theatre) became the presentation's current venue. == Awards of Merit categories == === Current categories === In the first year of the awards, the Best Directing award was split into two categories (Drama and Comedy). At times, the Best Original Score award has also been split into separate categories (Drama and Comedy/Musical). From the 1930s through the 1960s, the Art Direction (now Production Design), Cinematography, and Costume Design awards were likewise split into two categories (black-and-white films and color films). Prior to 2012, the Production Design award was called Art Direction, while the Makeup and Hairstyling award was called Makeup. In August 2018, the Academy announced several changes to future telecasts (starting with the 91st Academy Awards) including the addition of a new category: Best Popular Film, with eligibility requirements to come later. They also announced that several categories would not be televised live, but rather be recorded during commercial breaks and aired later in the ceremony. === Discontinued categories === === Proposed categories === The Board of Governors meets each year and considers new award categories. To date, the following proposed categories have been rejected: Best Casting: rejected in 1999 Best Stunt Coordination: rejected every year from 1991 to 2012 Best Title Design: rejected in 1999 == Special categories == The Special Academy Awards are voted on by special committees, rather than by the Academy membership as a whole. They are not always presented on a consistent annual basis. === Current special categories === For a list of all nine awards, see § Other awards presented by the Academy (above)Academy Honorary Award: since 1929 Academy Scientific and Technical Award (three different awards): since 1931 Gordon E. Sawyer Award: since 1981 Jean Hersholt Humanitarian Award: since 1957 Irving G. Thalberg Memorial Award: since 1938 Academy Special Achievement Award: from 1972 to 1995, and again for 2017 === Discontinued special categories === Academy Juvenile Award: 1934 to 1960 == Criticism == === Accusations of commercialism === Due to the positive exposure and prestige of the Academy Awards, studios spend millions of dollars and hire publicists specifically to promote their films during what is typically called the "Oscar season". This has generated accusations of the Academy Awards being influenced more by marketing than quality. William Friedkin, an Academy Award-winning film director and former producer of the ceremony, expressed this sentiment at a conference in New York in 2009, describing it as "the greatest promotion scheme that any industry ever devised for itself".Tim Dirks, editor of AMC's filmsite.org, has written of the Academy Awards, Unfortunately, the critical worth, artistic vision, cultural influence and innovative qualities of many films are not given the same voting weight. Especially since the 1980s, moneymaking "formula-made" blockbusters with glossy production values have often been crowd-pleasing titans (and Best Picture winners), but they haven't necessarily been great films with depth or critical acclaim by any measure. === Accusations of bias === Typical criticism of the Academy Awards for Best Picture is that among the winners and nominees there is an over-representation of romantic historical epics, biographical dramas, romantic dramedies, and family melodramas, most of which are released in the U.S. the last three months of the calendar year. The Oscars have been infamously known for selecting specific genres of movies to be awarded. This has led to the coining of the term 'Oscar bait', describing such movies. This has led at times to more specific criticisms that the Academy is disconnected from the audience, e.g., by favoring 'Oscar bait' over audience favorites, or favoring historical melodramas over critically acclaimed movies that depict current life issues. === Allegations of a lack of diversity === The Academy Awards have long received criticism over its lack of diversity among the nominees. This criticism is based on the statistics from every Academy Awards since 1929 which shows us that only 6.4% of academy award nominees have been non-white and since 1991, 11.2% of nominees have been non-white, with the rate of winners being even more polarizing . The 88th awards ceremony became the target of a boycott, popularized on social media by the #OscarsSoWhite, based on critics' perception that its all-white acting nominee list reflected bias. In response, the Academy initiated "historic" changes in membership by the year 2020. === Symbolism or sentimentalization === Acting prizes in certain years have been criticized for not recognizing superior performances so much as being awarded for personal popularity or presented as a "career honor" to recognize a distinguished nominee's entire body of work. === Refusing the award === Some winners critical of the Academy Awards have boycotted the ceremonies and refused to accept their Oscars. The first to do so was screenwriter Dudley Nichols (Best Writing in 1935 for The Informer). Nichols boycotted the 8th Academy Awards ceremony because of conflicts between the Academy and the Writers' Guild. Nichols eventually accepted the 1935 award three years later, at the 1938 ceremony. Nichols was nominated for three further Academy Awards during his career. George C. Scott became the second person to refuse his award (Best Actor in 1970 for Patton) at the 43rd Academy Awards ceremony. Scott described it as a 'meat parade', saying 'I don't want any part of it."The third person to refuse the award was Marlon Brando, who refused his award (Best Actor for 1972's The Godfather) citing the film industry's discrimination and mistreatment of Native Americans. At the 45th Academy Awards ceremony, Brando sent actress and civil rights activist Sacheen Littlefeather to read a 15-page speech detailing his criticisms. === Incidents === At the 2017 awards ceremony, Warren Beatty and Faye Dunaway mistakenly announced that La La Land was the Best Picture award recipient, instead of Moonlight, the actual winner. Dunaway, after hesitating during the announcement, handed the wrong envelope to Beatty, which listed Emma Stone as Best Actress for La La Land and led to the confusion. The proper winner was announced after the acceptance speeches by La La Land producers Jordan Horowitz, Marc Platt and Fred Berger. The following year, Beatty and Dunaway were invited back as announcers for Best Picture winner, which they accomplished without error. == Associated events == The following events are closely associated with the annual Academy Awards: César Award Nominees luncheon Governors Awards The 25th Independent Spirit Awards (in 2010), usually held in Santa Monica the Saturday before the Oscars, marked the first time it was moved to a Friday and a change of venue to L.A. Live The annual "Night Before", traditionally held at the Beverly Hills Hotel, begun in 2002 and generally known as the party of the season, benefits the Motion Picture and Television Fund, which operates a retirement home for SAG actors in the San Fernando Valley Elton John AIDS Foundation Academy Award Party airs the awards live at the nearby Pacific Design Center The Governors' Ball is the Academy's official after-party, including dinner (until 2011), and is adjacent to the awards-presentation venue The Vanity Fair after-party, historically at the former Morton's restaurant, since 2009 has been at the Sunset Tower == Presenter and performer gifts == It has become a tradition to give out gift bags to the presenters and performers at the Oscars. In recent years, these gifts have also been extended to award nominees and winners. The value of each of these gift bags can reach into the tens of thousands of dollars. In 2014, the value was reported to be as high as US$80,000. The value has risen to the point where the U.S. Internal Revenue Service issued a statement regarding the gifts and their taxable status. Oscar gift bags have included vacation packages to Hawaii and Mexico and Japan, a private dinner party for the recipient and friends at a restaurant, videophones, a four-night stay at a hotel, watches, bracelets, vacation packages, spa treatments, bottles of vodka, maple salad dressing, and weight-loss gummie candy. Some of the gifts have even had a "risque" element to them; in 2014, the adult products retailer Adam & Eve had a "Secret Room Gifting Suite". Celebrities visiting the gifting suite included Judith Hoag, Carolyn Hennesy, Kate Linder, Chris Mulkey, Jim O'Heir, and NBA player John Salley. == Television ratings and advertisement prices == From 2006 onwards, results are Live+SD, all previous years are Live viewing == Trademark == The term "Oscar" is a registered trademark of the AMPAS; however, in the Italian language, it is used generically to refer to any award or award ceremony, regardless of which field. == See also == List of film awards List of actors with Academy Award nominations == References == == Further reading == Brokaw, Lauren (2010).

### Instruction: retrieve labels for this: International Atomic Time (TAI, from the French name temps atomique international) is a high-precision atomic coordinate time standard based on the notional passage of proper time on Earth's geoid. It is the principal realisation of Terrestrial Time (except for a fixed offset of epoch). It is also the basis for Coordinated Universal Time (UTC), which is used for civil timekeeping all over the Earth's surface. As of 31 December 2016 when another leap second was added, TAI is exactly 37 seconds ahead of UTC. The 37 seconds results from the initial difference of 10 seconds at the start of 1972, plus 27 leap seconds in UTC since 1972. TAI may be reported using traditional means of specifying days, carried over from non-uniform time standards based on the rotation of the Earth. Specifically, both Julian Dates and the Gregorian calendar are used. TAI in this form was synchronised with Universal Time at the beginning of 1958, and the two have drifted apart ever since, due to the changing motion of the Earth. == Operation == TAI is a weighted average of the time kept by over 400 atomic clocks in over 50 national laboratories worldwide. The majority of the clocks involved are caesium clocks; the International System of Units (SI) definition of the second is based on caesium. The clocks are compared using GPS signals and two-way satellite time and frequency transfer. Due to the signal averaging TAI is an order of magnitude more stable than its best constituent clock. The participating institutions each broadcast, in real time, a frequency signal with timecodes, which is their estimate of TAI. Time codes are usually published in the form of UTC, which differs from TAI by a well-known integer number of seconds. These time scales are denoted in the form UTC(NPL) in the UTC form, where NPL in this case identifies the National Physical Laboratory, UK. The TAI form may be denoted TAI(NPL). The latter is not to be confused with TA(NPL), which denotes an independent atomic time scale, not synchronised to TAI or to anything else. The clocks at different institutions are regularly compared against each other. The International Bureau of Weights and Measures (BIPM, France), combines these measurements to retrospectively calculate the weighted average that forms the most stable time scale possible. This combined time scale is published monthly in "Circular T", and is the canonical TAI. This time scale is expressed in the form of tables of differences UTC-UTC(k) (equivalent to TAI-TAI(k)) for each participating institution k. The same circular also gives tables of TAI-TA(k), for the various unsynchronised atomic time scales. Errors in publication may be corrected by issuing a revision of the faulty Circular T or by errata in a subsequent Circular T. Aside from this, once published in Circular T, the TAI scale is not revised. In hindsight it is possible to discover errors in TAI, and to make better estimates of the true proper time scale. Since the published circulars are definitive, better estimates do not create another version of TAI; it is instead considered to be creating a better realisation of Terrestrial Time (TT). == History == Early atomic time scales consisted of quartz clocks with frequencies calibrated by a single atomic clock; the atomic clocks were not operated continuously. Atomic timekeeping services started experimentally in 1955, using the first caesium atomic clock at the National Physical Laboratory, UK (NPL) and was used as a basis for calibrating the quartz clocks at the Royal Greenwich Observatory. The International Time Bureau (BIH) began a time scale, Tm or AM, in July 1955, using both local caesium clocks and comparisons to distant clocks using the phase of VLF radio signals. The United States Naval Observatory began the A.1 scale 13 September 1956, using an Atomichron commercial atomic clock, followed by the NBS-A scale at the National Bureau of Standards, Boulder, Colorado. Both the BIH scale and A.1 were defined by an epoch at the beginning of 1958 The procedures used by the BIH evolved, and the name for the time scale changed: "A3" in 1963 and "TA(BIH)" in 1969. This synchronisation was inevitably imperfect, depending as it did on the astronomical realisation of UT2. At the time, UT2 as published by various observatories differed by several hundredths of a second. The SI second was defined in terms of the caesium atom in 1967, and in 1971 the name International Atomic Time (TAI) was assigned to a time scale based on SI seconds with no leap seconds. During this time, irregularities in the atomic time were detected and corrected. In 1967 it was suggested that nearby masses caused clocks to operate at different rates, but this was disproven in 1968.In the 1970s, it became clear that the clocks participating in TAI were ticking at different rates due to gravitational time dilation, and the combined TAI scale therefore corresponded to an average of the altitudes of the various clocks. Starting from Julian Date 2443144.5 (1 January 1977 00:00:00), corrections were applied to the output of all participating clocks, so that TAI would correspond to proper time at mean sea level (the geoid). Because the clocks were, on average, well above sea level, this meant that TAI slowed down, by about one part in a trillion. The former uncorrected time scale continues to be published, under the name EAL (Echelle Atomique Libre, meaning Free Atomic Scale).The instant that the gravitational correction started to be applied serves as the epoch for Barycentric Coordinate Time (TCB), Geocentric Coordinate Time (TCG), and Terrestrial Time (TT), which represent three fundamental time scales in the solar system. All three of these time scales were defined to read JD 2443144.5003725 (1 January 1977 00:00:32.184) exactly at that instant. TAI was henceforth a realisation of TT, with the equation TT(TAI) = TAI + 32.184 s.The continued existence of TAI was questioned in a 2007 letter from the BIPM to the ITU-R which stated "In the case of a redefinition of UTC without leap seconds, the CCTF would consider discussing the possibility of suppressing TAI, as it would remain parallel to the continuous UTC." == Relation to UTC == UTC is a discontinuous (i.e. regularly adjusted by leap seconds) time scale composed from segments that are linear transformations of atomic time. From its beginning in 1961 through December 1971 the adjustments were made regularly in fractional leap seconds so that UTC approximated UT2. Afterwards these adjustments were made only in whole seconds to approximate UT1. This was a compromise arrangement in order to enable a publicly broadcast time scale; the post-1971 more linear transformation of the BIH's atomic time meant that the time scale would be more stable and easier to synchronize internationally. The fact that it continues to approximate UT1 means that tasks such as navigation which require a source of Universal Time continue to be well served by the public broadcast of UTC. == See also == Clock synchronization Network Time Protocol Precision Time Protocol Time and frequency transfer == Notes == == References == == Bibliography == == External links == Bureau International des Poids et Mesures: TAI Time and Frequency Section - National Physical Laboratory, UK IERS website NIST Web Clock FAQs History of time scales NIST-F1 Cesium Fountain Atomic Clock "Optical frequency comb for metrology and timekeeping".

### Instruction: retrieve labels for this: Ayn Rand (; born Alisa Zinovyevna Rosenbaum; February 2 [O.S. January 20] 1905 – March 6, 1982) was a Russian-American novelist, playwright, screenwriter and philosopher. She is known for her two best-selling novels, The Fountainhead and Atlas Shrugged, and for developing a philosophical system she named Objectivism. Educated in Russia, she moved to the United States in 1926. She had a play produced on Broadway in 1935 and 1936. After two early novels that were initially unsuccessful, she achieved fame with her 1943 novel, The Fountainhead. In 1957, Rand published her best-known work, the novel Atlas Shrugged. Afterward, she turned to non-fiction to promote her philosophy, publishing her own periodicals and releasing several collections of essays until her death in 1982. Rand advocated reason as the only means of acquiring knowledge and rejected faith and religion. She supported rational and ethical egoism and rejected altruism. In politics, she condemned the initiation of force as immoral and opposed collectivism and statism as well as anarchism, instead supporting laissez-faire capitalism, which she defined as the system based on recognizing individual rights, including property rights. In art, Rand promoted romantic realism. She was sharply critical of most philosophers and philosophical traditions known to her, except for Aristotle, Thomas Aquinas and classical liberals.Literary critics received Rand's fiction with mixed reviews and academia generally ignored or rejected her philosophy, though academic interest has increased in recent decades. The Objectivist movement attempts to spread her ideas, both to the public and in academic settings. She has been a significant influence among libertarians and American conservatives. == Life == === Early life === Rand was born Alisa Zinovyevna Rosenbaum (Russian: Али́са Зиновьевна Розенбаум) on February 2, 1905, to a Russian-Jewish bourgeois family living in Saint Petersburg. She was the eldest of three daughters of Zinovy Zakharovich Rosenbaum and his wife, Anna Borisovna (née Kaplan). Her father was upwardly mobile and a pharmacist and her mother was socially ambitious and religiously observant. Rand later said she found school unchallenging and began writing screenplays at the age of eight and novels at the age of ten. At the prestigious Stoiunina Gymnasium, her closest friend was Vladimir Nabokov's younger sister, Olga. The two girls shared an intense interest in politics and would engage in debates at the Nabokov mansion: while Nabokova defended constitutional monarchy, Rand supported republican ideals.She was twelve at the time of the February Revolution of 1917, during which she favored Alexander Kerensky over Tsar Nicholas II. The subsequent October Revolution and the rule of the Bolsheviks under Vladimir Lenin disrupted the life the family had previously enjoyed. Her father's business was confiscated, and the family fled to the Crimean Peninsula, which was initially under control of the White Army during the Russian Civil War. While in high school, Rand decided that she was an atheist and valued reason above any other human virtue. After graduating from high school in the Crimea in June 1921, Rand returned with her family to Petrograd (as Saint Petersburg was renamed at that time), where they faced desperate conditions, on occasion nearly starving. After the Russian Revolution, universities were opened to women, allowing Rand to be in the first group of women to enroll at Petrograd State University. At the age of 16, she began her studies in the department of social pedagogy, majoring in history. At the university she was introduced to the writings of Aristotle and Plato, who would be her greatest influence and counter-influence, respectively. She also studied the philosophical works of Friedrich Nietzsche. Able to read French, German and Russian, Rand also discovered the writers Fyodor Dostoevsky, Victor Hugo, Edmond Rostand, and Friedrich Schiller, who became her perennial favorites.Along with many other bourgeois students, Rand was purged from the university shortly before graduating. After complaints from a group of visiting foreign scientists, however, many of the purged students were allowed to complete their work and graduate, which Rand did in October 1924. She then studied for a year at the State Technicum for Screen Arts in Leningrad. For an assignment she wrote an essay about the Polish actress Pola Negri, which became her first published work.By this time she had decided her professional surname for writing would be Rand, possibly because it is graphically similar to a vowelless excerpt Рзнб of her birth surname in Cyrillic handwriting, and she adopted the first name Ayn, either from a Finnish name Aino or from the Hebrew word עין (ayin, meaning "eye"). === Arrival in the United States === In late 1925, Rand was granted a visa to visit relatives in Chicago. She departed on January 17, 1926. When she arrived in New York City on February 19, 1926, she was so impressed with the skyline of Manhattan that she cried what she later called "tears of splendor". Intent on staying in the United States to become a screenwriter, she lived for a few months with her relatives, one of whom owned a movie theater and allowed her to watch dozens of films for free. She then left for Hollywood, California.In Hollywood, a chance meeting with famed director Cecil B. DeMille led to work as an extra in his film The King of Kings and a subsequent job as a junior screenwriter. While working on The King of Kings, she met an aspiring young actor, Frank O'Connor; the two were married on April 15, 1929. She became a permanent American resident in July 1929 and an American citizen on March 3, 1931. Taking various jobs during the 1930s to support her writing, she worked for a time as the head of the costume department at RKO Studios. She made several attempts to bring her parents and sisters to the United States, but they were unable to acquire permission to emigrate. === Early fiction === Rand's first literary success came with the sale of her screenplay Red Pawn to Universal Studios in 1932, although it was never produced. This was followed by the courtroom drama Night of January 16th, first produced by E. E. Clive in Hollywood in 1934 and then successfully reopened on Broadway in 1935. Each night a jury was selected from members of the audience; based on the jury's vote, one of two different endings would be performed. In 1941, Paramount Pictures produced a movie loosely based on the play. Rand did not participate in the production and was highly critical of the result. Ideal is a novel and play written in 1934 which were first published in 2015 by her estate. The heroine is an actress who embodies Randian ideals.Rand's first published novel, the semi-autobiographical We the Living, was published in 1936. Set in Soviet Russia, it focused on the struggle between the individual and the state. In a 1959 foreword to the novel, Rand stated that We the Living "is as near to an autobiography as I will ever write. It is not an autobiography in the literal, but only in the intellectual sense. The plot is invented, the background is not ..." Initial sales were slow and the American publisher let it go out of print, although European editions continued to sell. After the success of her later novels, Rand was able to release a revised version in 1959 that has since sold over three million copies. In 1942, without Rand's knowledge or permission, the novel was made into a pair of Italian films, Noi vivi and Addio, Kira. Rediscovered in the 1960s, these films were re-edited into a new version which was approved by Rand and re-released as We the Living in 1986.Her novella Anthem was written during a break from the writing of her next major novel, The Fountainhead. It presents a vision of a dystopian future world in which totalitarian collectivism has triumphed to such an extent that even the word 'I' has been forgotten and replaced with 'we'. It was published in England in 1938, but Rand initially could not find an American publisher. As with We the Living, Rand's later success allowed her to get a revised version published in 1946, which has sold more than 3.5 million copies. === The Fountainhead and political activism === During the 1940s, Rand became politically active. She and her husband worked as full-time volunteers for the 1940 presidential campaign of Republican Wendell Willkie. This work led to Rand's first public speaking experiences; she enjoyed fielding sometimes hostile questions from New York City audiences who had viewed pro-Willkie newsreels. This activity brought her into contact with other intellectuals sympathetic to free-market capitalism. She became friends with journalist Henry Hazlitt and his wife, and Hazlitt introduced her to the Austrian School economist Ludwig von Mises. Despite her philosophical differences with them, Rand strongly endorsed the writings of both men throughout her career, and both of them expressed admiration for her. Mises once referred to Rand as "the most courageous man in America", a compliment that particularly pleased her because he said "man" instead of "woman". Rand also became friends with libertarian writer Isabel Paterson. Rand questioned Paterson about American history and politics long into the night during their many meetings and gave Paterson ideas for her only non-fiction book, The God of the Machine.Rand's first major success as a writer came in 1943 with The Fountainhead, a romantic and philosophical novel that she wrote over a period of seven years. The novel centers on an uncompromising young architect named Howard Roark and his struggle against what Rand described as "second-handers"—those who attempt to live through others, placing others above themselves. It was rejected by twelve publishers before finally being accepted by the Bobbs-Merrill Company on the insistence of editor Archibald Ogden, who threatened to quit if his employer did not publish it. While completing the novel, Rand was prescribed the amphetamine Benzedrine to fight fatigue. The drug helped her to work long hours to meet her deadline for delivering the novel, but afterwards she was so exhausted that her doctor ordered two weeks' rest. Her use of the drug for approximately three decades may have contributed to what some of her later associates described as volatile mood swings.The Fountainhead became a worldwide success, bringing Rand fame and financial security. In 1943, Rand sold the rights for a film version to Warner Bros. and she returned to Hollywood to write the screenplay. Finishing her work on that screenplay, she was hired by producer Hal B. Wallis as a screenwriter and script-doctor. Her work for Wallis included the screenplays for the Oscar-nominated Love Letters and You Came Along. Rand also worked on other projects, including a planned nonfiction treatment of her philosophy to be called The Moral Basis of Individualism. Although the planned book was never completed, a condensed version was published as an essay titled "The Only Path to Tomorrow" in the January 1944 edition of Reader's Digest magazine. Rand extended her involvement with free-market and anti-communist activism while working in Hollywood. She became involved with the Motion Picture Alliance for the Preservation of American Ideals, a Hollywood anti-Communist group, and wrote articles on the group's behalf. She also joined the anti-Communist American Writers Association. A visit by Isabel Paterson to meet with Rand's California associates led to a final falling out between the two when Paterson made comments, which Rand considered rude, to valued political allies. In 1947, during the Second Red Scare, Rand testified as a "friendly witness" before the United States House Un-American Activities Committee. Her testimony described the disparity between her personal experiences in the Soviet Union and the portrayal of it in the 1944 film Song of Russia. Rand argued that the film grossly misrepresented conditions in the Soviet Union, portraying life there as much better and happier than it actually was. She wanted to also criticize the lauded 1946 film The Best Years of Our Lives for what she interpreted as its negative presentation of the business world, but she was not allowed to testify about it. When asked after the hearings about her feelings on the effectiveness of the investigations, Rand described the process as "futile".After several delays, the film version of The Fountainhead was released in 1949. Although it used Rand's screenplay with minimal alterations, she "disliked the movie from beginning to end", and complained about its editing, acting, and other elements. === Atlas Shrugged and Objectivism === In the years following the publication of The Fountainhead, Rand received numerous letters from readers, some of whom the book profoundly influenced. In 1951 Rand moved from Los Angeles to New York City, where she gathered a group of these admirers around her. This group (jokingly designated "The Collective") included future Federal Reserve Chairman Alan Greenspan, a young psychology student named Nathan Blumenthal (later Nathaniel Branden) and his wife Barbara and Barbara's cousin Leonard Peikoff. Initially the group was an informal gathering of friends who met with Rand on weekends at her apartment to discuss philosophy. She later began allowing them to read the drafts of her new novel, Atlas Shrugged, as the manuscript pages were written. In 1954 Rand's close relationship with the younger Nathaniel Branden turned into a romantic affair, with the consent of their spouses.Atlas Shrugged, published in 1957, was considered Rand's magnum opus. Rand described the theme of the novel as "the role of the mind in man's existence—and, as a corollary, the demonstration of a new moral philosophy: the morality of rational self-interest". It advocates the core tenets of Rand's philosophy of Objectivism and expresses her concept of human achievement. The plot involves a dystopian United States in which the most creative industrialists, scientists, and artists respond to a welfare state government by going on strike and retreating to a mountainous hideaway where they build an independent free economy. The novel's hero and leader of the strike, John Galt, describes the strike as "stopping the motor of the world" by withdrawing the minds of the individuals most contributing to the nation's wealth and achievement. With this fictional strike, Rand intended to illustrate that without the efforts of the rational and productive, the economy would collapse and society would fall apart. The novel includes elements of mystery, romance, and science fiction, and it contains an extended exposition of Objectivism in the form of a lengthy monologue delivered by Galt.Despite many negative reviews, Atlas Shrugged became an international bestseller. In an interview with Mike Wallace, Rand declared herself "the most creative thinker alive". However, Rand was discouraged and depressed by the reaction of intellectuals to the novel. Atlas Shrugged was Rand's last completed work of fiction; it marked the end of her career as a novelist and the beginning of her role as a popular philosopher.In 1958, Nathaniel Branden established Nathaniel Branden Lectures, later incorporated as the Nathaniel Branden Institute (NBI), to promote Rand's philosophy. Collective members gave lectures for NBI and wrote articles for Objectivist periodicals that she edited. Rand later published some of these articles in book form. Critics, including some former NBI students and Branden himself, later described the culture of NBI as one of intellectual conformity and excessive reverence for Rand, with some describing NBI or the Objectivist movement itself as a cult or religion. Rand expressed opinions on a wide range of topics, from literature and music to sexuality and facial hair, and some of her followers mimicked her preferences, wearing clothes to match characters from her novels and buying furniture like hers. However, some former NBI students believed the extent of these behaviors was exaggerated, and the problem was concentrated among Rand's closest followers in New York. Rand was unimpressed with many of the NBI students and held them to strict standards, sometimes reacting coldly or angrily to those who disagreed with her. === Later years === Throughout the 1960s and 1970s, Rand developed and promoted her Objectivist philosophy through her nonfiction works and by giving talks to students at institutions such as Yale, Princeton, Columbia, Harvard, and the Massachusetts Institute of Technology. She received an honorary Doctorate of Humane Letters from Lewis & Clark College on 2 October 1963. She also began delivering annual lectures at the Ford Hall Forum, responding afterward to questions from the audience. During these speeches and Q&A sessions, she often took controversial stances on political and social issues of the day. These included supporting abortion rights, opposing the Vietnam War and the military draft (but condemning many draft dodgers as "bums"), supporting Israel in the Yom Kippur War of 1973 against a coalition of Arab nations as "civilized men fighting savages", saying European colonists had the right to develop land taken from American Indians, and calling homosexuality "immoral" and "disgusting", while also advocating the repeal of all laws about it. She also endorsed several Republican candidates for President of the United States, most strongly Barry Goldwater in 1964, whose candidacy she promoted in several articles for The Objectivist Newsletter. In 1964, Nathaniel Branden began an affair with the young actress Patrecia Scott, whom he later married. Nathaniel and Barbara Branden kept the affair hidden from Rand. When she learned of it in 1968, though her romantic relationship with Branden had already ended, Rand terminated her relationship with both Brandens, which led to the closure of NBI. Rand published an article in The Objectivist repudiating Nathaniel Branden for dishonesty and other "irrational behavior in his private life". Branden later apologized in an interview to "every student of Objectivism" for "perpetuating the Ayn Rand mystique" and for "contributing to that dreadful atmosphere of intellectual repressiveness that pervades the Objectivist movement". In subsequent years, Rand and several more of her closest associates parted company.Rand underwent surgery for lung cancer in 1974 after decades of heavy smoking. In 1976, she retired from writing her newsletter and, despite her initial objections, she allowed Evva Pryor, an employee of her attorney, to enroll her in Social Security and Medicare. During the late 1970s her activities within the Objectivist movement declined, especially after the death of her husband on November 9, 1979. One of her final projects was work on a never-completed television adaptation of Atlas Shrugged.Rand died of heart failure on March 6, 1982, at her home in New York City, and was interred in the Kensico Cemetery, Valhalla, New York. Rand's funeral was attended by some of her prominent followers, including Alan Greenspan. A 6-foot (1.8 m) floral arrangement in the shape of a dollar sign was placed near her casket. In her will, Rand named Leonard Peikoff to inherit her estate. == Philosophy == Rand called her philosophy "Objectivism", describing its essence as "the concept of man as a heroic being, with his own happiness as the moral purpose of his life, with productive achievement as his noblest activity, and reason as his only absolute". She considered Objectivism a systematic philosophy and laid out positions on metaphysics, epistemology, ethics, political philosophy, and aesthetics.In metaphysics, Rand supported philosophical realism, and opposed anything she regarded as mysticism or supernaturalism, including all forms of religion.In epistemology, she considered all knowledge to be based on sense perception, the validity of which she considered axiomatic, and reason, which she described as "the faculty that identifies and integrates the material provided by man's senses". She rejected all claims of non-perceptual or a priori knowledge, including "'instinct,' 'intuition,' 'revelation,' or any form of 'just knowing'". In her Introduction to Objectivist Epistemology, Rand presented a theory of concept formation and rejected the analytic–synthetic dichotomy.In ethics, Rand argued for rational and ethical egoism (rational self-interest), as the guiding moral principle. She said the individual should "exist for his own sake, neither sacrificing himself to others nor sacrificing others to himself". She referred to egoism as "the virtue of selfishness" in her book of that title, in which she presented her solution to the is-ought problem by describing a meta-ethical theory that based morality in the needs of "man's survival qua man". She condemned ethical altruism as incompatible with the requirements of human life and happiness, and held that the initiation of force was evil and irrational, writing in Atlas Shrugged that "Force and mind are opposites."Rand's political philosophy emphasized individual rights (including property rights), and she considered laissez-faire capitalism the only moral social system because in her view it was the only system based on the protection of those rights. She opposed statism, which she understood to include theocracy, absolute monarchy, Nazism, fascism, communism, democratic socialism, and dictatorship. Rand believed that natural rights should be enforced by a constitutionally limited government. Although her political views are often classified as conservative or libertarian, she preferred the term "radical for capitalism". She worked with conservatives on political projects, but disagreed with them over issues such as religion and ethics. She denounced libertarianism, which she associated with anarchism. She rejected anarchism as a naïve theory based in subjectivism that could only lead to collectivism in practice.In aesthetics, Rand defined art as a "selective re-creation of reality according to an artist's metaphysical value-judgments". According to her, art allows philosophical concepts to be presented in a concrete form that can be easily grasped, thereby fulfilling a need of human consciousness. As a writer, the art form Rand focused on most closely was literature, where she considered romanticism to be the approach that most accurately reflected the existence of human free will. She described her own approach to literature as "romantic realism".Rand acknowledged Aristotle as her greatest influence and remarked that in the history of philosophy she could only recommend "three A's"—Aristotle, Aquinas, and Ayn Rand. In a 1959 interview with Mike Wallace, when asked where her philosophy came from she responded: "Out of my own mind, with the sole acknowledgement of a debt to Aristotle, the only philosopher who ever influenced me. I devised the rest of my philosophy myself." However, she also found early inspiration in Friedrich Nietzsche, and scholars have found indications of his influence in early notes from Rand's journals, in passages from the first edition of We the Living (which Rand later revised), and in her overall writing style. However, by the time she wrote The Fountainhead, Rand had turned against Nietzsche's ideas, and the extent of his influence on her even during her early years is disputed. Among the philosophers Rand held in particular disdain was Immanuel Kant, whom she referred to as a "monster", although philosophers George Walsh and Fred Seddon have argued that she misinterpreted Kant and exaggerated their differences. Rand said her most important contributions to philosophy were her "theory of concepts, [her] ethics, and [her] discovery in politics that evil—the violation of rights—consists of the initiation of force". She believed epistemology was a foundational branch of philosophy and considered the advocacy of reason to be the single most significant aspect of her philosophy, stating: "I am not primarily an advocate of capitalism, but of egoism; and I am not primarily an advocate of egoism, but of reason. If one recognizes the supremacy of reason and applies it consistently, all the rest follows." == Reception and legacy == === Critical reception === During Rand's lifetime, her work evoked both extreme praise and condemnation. Rand's first novel, We the Living, was admired by the literary critic H. L. Mencken, her Broadway play Night of January 16th was both a critical and popular success, and The Fountainhead was hailed by a reviewer in The New York Times as "masterful". Rand's novels were derided by some critics when they were first published as being long and melodramatic. However, they became bestsellers largely through word of mouth.The first reviews Rand received were for Night of January 16th. Reviews of the production were largely positive, but Rand considered even positive reviews to be embarrassing because of significant changes made to her script by the producer. Rand believed that her first novel, We the Living, was not widely reviewed, but Rand scholar Michael S. Berliner says "it was the most reviewed of any of her works", with approximately 125 different reviews being published in more than 200 publications. Overall these reviews were more positive than the reviews she received for her later work. Her 1938 novella Anthem received little attention from reviewers, both for its first publication in England and for subsequent re-issues.Rand's first bestseller, The Fountainhead, received far fewer reviews than We the Living, and reviewers' opinions were mixed. There was a positive review in The New York Times that Rand greatly appreciated. The reviewer called Rand "a writer of great power" who wrote "brilliantly, beautifully and bitterly", and stated that "you will not be able to read this masterful book without thinking through some of the basic concepts of our time". There were other positive reviews, but Rand dismissed most of them as either not understanding her message or as being from unimportant publications. Some negative reviews focused on the length of the novel, such as one that called it "a whale of a book" and another that said "anyone who is taken in by it deserves a stern lecture on paper-rationing". Other negative reviews called the characters unsympathetic and Rand's style "offensively pedestrian".Rand's 1957 novel Atlas Shrugged was widely reviewed and many of the reviews were strongly negative. In National Review, conservative author Whittaker Chambers called the book "sophomoric" and "remarkably silly". He described the tone of the book as "shrillness without reprieve" and accused Rand of supporting a godless system (which he related to that of the Soviets), claiming "From almost any page of Atlas Shrugged, a voice can be heard, from painful necessity, commanding: 'To a gas chamber—go!'". Atlas Shrugged received positive reviews from a few publications, including praise from the noted book reviewer John Chamberlain, but Rand scholar Mimi Reisel Gladstein later wrote that "reviewers seemed to vie with each other in a contest to devise the cleverest put-downs", calling it "execrable claptrap" and "a nightmare"—they also said it was "written out of hate" and showed "remorseless hectoring and prolixity".Rand's nonfiction received far fewer reviews than her novels had. The tenor of the criticism for her first nonfiction book, For the New Intellectual, was similar to that for Atlas Shrugged, with philosopher Sidney Hook likening her certainty to "the way philosophy is written in the Soviet Union", and author Gore Vidal calling her viewpoint "nearly perfect in its immorality". Her subsequent books got progressively less attention from reviewers.On the 100th anniversary of Rand's birth in 2005, Edward Rothstein, writing for The New York Times, referred to her fictional writing as quaint utopian "retro fantasy" and programmatic neo-Romanticism of the misunderstood artist while criticizing her characters' "isolated rejection of democratic society". In 2007, book critic Leslie Clark described her fiction as "romance novels with a patina of pseudo-philosophy". In 2009, GQ's critic columnist Tom Carson described her books as "capitalism's version of middlebrow religious novels" such as Ben-Hur and the Left Behind series. === Popular interest === In 1991, a survey conducted for the Library of Congress and the Book-of-the-Month Club asked club members what the most influential book in the respondent's life was. Rand's Atlas Shrugged was the second most popular choice, after the Bible. Rand's books continue to be widely sold and read, with over 29 million copies sold as of 2013 (with about 10% of that total purchased for free distribution to schools by the Ayn Rand Institute). In 1998, Modern Library readers voted Atlas Shrugged the 20th century's finest work of fiction, followed by The Fountainhead in second place, Anthem in seventh, and We the Living eighth; none of the four appeared on the critics' list. Although Rand's influence has been greatest in the United States, there has been international interest in her work. Rand's work continues to be among the top sellers among books in India.Rand's contemporary admirers included fellow novelists, such as Ira Levin, Kay Nolte Smith and L. Neil Smith; and later writers such as Erika Holzer and Terry Goodkind have been influenced by her. Other artists who have cited Rand as an important influence on their lives and thought include comic book artist Steve Ditko and musician Neil Peart of Rush. Rand provided a positive view of business and in response business executives and entrepreneurs have admired and promoted her work. John Allison of BB&T and Ed Snider of Comcast Spectacor have funded the promotion of Rand's ideas, while Mark Cuban (owner of the Dallas Mavericks) as well as John P. Mackey (CEO of Whole Foods) among others have said they consider Rand crucial to their success.Rand and her works have been referred to in a variety of media: on television shows including animated sitcoms, live-action comedies, dramas, and game shows, as well as in movies and video games. She, or a character based on her, figures prominently (in positive and negative lights) in literary and science fiction novels by prominent American authors. Nick Gillespie, editor in chief of Reason, has remarked that "Rand's is a tortured immortality, one in which she's as likely to be a punch line as a protagonist..." and that "jibes at Rand as cold and inhuman, run through the popular culture". Two movies have been made about Rand's life. A 1997 documentary film, Ayn Rand: A Sense of Life, was nominated for the Academy Award for Best Documentary Feature. The Passion of Ayn Rand, a 1999 television adaptation of the book of the same name, won several awards. Rand's image also appears on a 1999 U.S. postage stamp illustrated by artist Nick Gaetano. === Political influence === Although she rejected the labels "conservative" and "libertarian", Rand has had continuing influence on right-wing politics and libertarianism. Jim Powell, a senior fellow at the Cato Institute, considers Rand one of the three most important women (along with Rose Wilder Lane and Isabel Paterson) of modern American libertarianism, and David Nolan, one of the founders of the Libertarian Party, stated that "without Ayn Rand, the libertarian movement would not exist". In his history of the libertarian movement, journalist Brian Doherty described her as "the most influential libertarian of the twentieth century to the public at large" and biographer Jennifer Burns referred to her as "the ultimate gateway drug to life on the right". Economist and Ayn Rand student George Reisman wrote: "Ayn Rand...in particular, must be cited as providing a philosophical foundation for the case of capitalism, and as being responsible probably more than anyone else for the current spread of pro-capitalist ideas." She faced intense opposition from William F. Buckley, Jr. and other contributors for the National Review magazine. They published numerous criticisms in the 1950s and 1960s by Whittaker Chambers, Garry Wills, and M. Stanton Evans. Nevertheless, her influence among conservatives forced Buckley and other National Review contributors to reconsider how traditional notions of virtue and Christianity could be integrated with support for capitalism.The political figures who cite Rand as an influence are usually conservatives (often members of the Republican Party), despite Rand taking some positions that are atypical for conservatives, such as being pro-choice and an atheist. A 1987 article in The New York Times referred to her as the Reagan administration's "novelist laureate". Republican Congressmen and conservative pundits have acknowledged her influence on their lives and have recommended her novels.The financial crisis of 2007–2008 spurred renewed interest in her works, especially Atlas Shrugged, which some saw as foreshadowing the crisis. Opinion articles compared real-world events with the plot of the novel. During this time, signs mentioning Rand and her fictional hero John Galt appeared at Tea Party protests. There was also increased criticism of her ideas, especially from the political left, with critics blaming the economic crisis on her support of selfishness and free markets, particularly through her influence on Alan Greenspan. For example, Mother Jones remarked that "Rand's particular genius has always been her ability to turn upside down traditional hierarchies and recast the wealthy, the talented, and the powerful as the oppressed" while equating Randian individual well-being with that of the Volk according to Goebbels. Corey Robin of The Nation alleged similarities between the "moral syntax of Randianism" and fascism. === Academic reaction === During Rand's lifetime her work received little attention from academic scholars. When the first academic book about Rand's philosophy appeared in 1971, its author declared writing about Rand "a treacherous undertaking" that could lead to "guilt by association" for taking her seriously. A few articles about Rand's ideas appeared in academic journals before her death in 1982, many of them in The Personalist. One of these was "On the Randian Argument" by libertarian philosopher Robert Nozick, who argued that her meta-ethical argument is unsound and fails to solve the is–ought problem posed by David Hume. Some responses to Nozick by other academic philosophers were also published in The Personalist arguing that Nozick misstated Rand's case. Academic consideration of Rand as a literary figure during her life was even more limited. Academic Mimi Gladstein was unable to find any scholarly articles about Rand's novels when she began researching her in 1973, and only three such articles appeared during the rest of the 1970s.Since Rand's death, interest in her work has gradually increased. Historian Jennifer Burns has identified "three overlapping waves" of scholarly interest in Rand, the most recent of which is "an explosion of scholarship" since the year 2000. However, few universities currently include Rand or Objectivism as a philosophical specialty or research area, with many literature and philosophy departments dismissing her as a pop culture phenomenon rather than a subject for serious study.Gladstein, Harry Binswanger, Allan Gotthelf, John Hospers, Edwin A. Locke, Wallace Matson, Leonard Peikoff, Chris Matthew Sciabarra, and Tara Smith have taught her work in academic institutions. Sciabarra co-edits the Journal of Ayn Rand Studies, a nonpartisan peer-reviewed journal dedicated to the study of Rand's philosophical and literary work. In 1987 Gotthelf, George Walsh and David Kelley co-founded the Ayn Rand Society, a group affiliated with the American Philosophical Association. In 2012, the University of Pittsburgh Press launched an "Ayn Rand Society Philosophical Studies" series based on the proceedings of the Society. Smith has written several academic books and papers on Rand's ideas, including Ayn Rand's Normative Ethics: The Virtuous Egoist, a volume on Rand's ethical theory published by Cambridge University Press. Rand's ideas have also been made subjects of study at Clemson and Duke universities. Scholars of English and American literature have largely ignored her work, although attention to her literary work has increased since the 1990s.Rand scholars Douglas Den Uyl and Douglas B. Rasmussen, while stressing the importance and originality of her thought, describe her style as "literary, hyperbolic and emotional". Philosopher Jack Wheeler says that despite "the incessant bombast and continuous venting of Randian rage", Rand's ethics are "a most immense achievement, the study of which is vastly more fruitful than any other in contemporary thought". In the Literary Encyclopedia entry for Rand written in 2001, John David Lewis declared that "Rand wrote the most intellectually challenging fiction of her generation". In a 1999 interview in the Chronicle of Higher Education, Sciabarra commented, "I know they laugh at Rand", while forecasting a growth of interest in her work in the academic community.Libertarian philosopher Michael Huemer argues that very few people find Rand's ideas convincing, especially her ethics, which he believes are difficult to interpret and may lack logical coherence. He attributes the attention she receives to her being a "compelling writer", especially as a novelist. Atlas Shrugged thus outsells Rand's non-fiction works as well as the works of other philosophers of classical liberalism such as Ludwig von Mises, Friedrich Hayek, or Frederic Bastiat.Political scientist Charles Murray, while praising Rand's literary accomplishments, criticizes her claim that her only "philosophical debt" was to Aristotle, instead asserting that her ideas were derivative of previous thinkers such as John Locke and Friedrich Nietzsche. Although Rand maintained that Objectivism was an integrated philosophical system, philosopher Robert H. Bass argues that her central ethical ideas are inconsistent and contradictory to her central political ideas. === Objectivist movement === In 1985, Rand's intellectual heir Leonard Peikoff established the Ayn Rand Institute, a nonprofit organization dedicated to promoting Rand's ideas and works. In 1990, after an ideological disagreement with Peikoff, philosopher David Kelley founded the Institute for Objectivist Studies, now known as The Atlas Society. In 2001, historian John McCaskey organized the Anthem Foundation for Objectivist Scholarship, which provides grants for scholarly work on Objectivism in academia. The charitable foundation of BB&T Corporation has also given grants for teaching Rand's ideas or works. The University of Texas at Austin, the University of Pittsburgh, and University of North Carolina at Chapel Hill are among the schools that have received grants. In some cases, these grants have been controversial due to their requiring research or teaching related to Rand. == Selected works == Novels: 1936 We the Living 1943 The Fountainhead 1957 Atlas ShruggedOther fiction: 1934 Night of January 16th 1938 Anthem 2015 IdealNon-fiction: 1961 For the New Intellectual 1964 The Virtue of Selfishness 1966 Capitalism: The Unknown Ideal 1969 The Romantic Manifesto 1971 The New Left: The Anti-Industrial Revolution 1979 Introduction to Objectivist Epistemology 1982 Philosophy: Who Needs It == See also == Letters of Ayn Rand Journals of Ayn Rand Murder of Marion Parker == Notes == == References == === Works cited === == External links == Ayn Rand at Encyclopædia Britannica Frequently Asked Questions About Ayn Rand from the Ayn Rand Institute Works by Ayn Rand at Project Gutenberg Works by or about Ayn Rand at Internet Archive Works by Ayn Rand at LibriVox (public domain audiobooks) Rand's papers at The Library of Congress Ayn Rand Lexicon – searchable database Hicks, Stephen R.

### Instruction: retrieve labels for this: This is a list of characters in Ayn Rand's novel Atlas Shrugged. == Major characters == The following are major characters from the novel. === Protagonists === ==== Dagny Taggart ==== Dagny Taggart is the protagonist of the novel. She is Vice-President in Charge of Operations for Taggart Transcontinental, under her brother, James Taggart. Given James' incompetence, Dagny is responsible for all the workings of the railroad. ==== Francisco d'Anconia ==== Francisco d'Anconia is one of the central characters in Atlas Shrugged, an owner by inheritance of the world's largest copper mining operation. He is a childhood friend, and the first love, of Dagny Taggart. A child prodigy of exceptional talents, Francisco was dubbed the "climax" of the d'Anconia line, an already prestigious family of skilled industrialists. He was a classmate of John Galt and Ragnar Danneskjöld and student of both Hugh Akston and Robert Stadler. He began working while still in school, proving that he could have made a fortune without the aid of his family's wealth and power. Later, Francisco bankrupts the d'Anconia business to put it out of others' reach. His full name is given as "Francisco Domingo Carlos Andres Sebastián d'Anconia". ==== John Galt ==== John Galt is the primary male hero of Atlas Shrugged. He initially appears as an unnamed menial worker for Taggart Transcontinental, who often dines with Eddie Willers in the employees' cafeteria, and leads Eddie to reveal important information about Dagny Taggart and Taggart Transcontinental. Only Eddie's side of their conversations is given in the novel. Later in the novel, the reader discovers this worker's true identity. Before working for Taggart Transcontinental, Galt worked as an engineer for the Twentieth Century Motor Company, where he secretly invented a generator of usable electric energy from ambient static electricity, but abandoned his prototype, and his employment, when dissatisfied by an easily corrupted novel system of payment. This prototype was found by Dagny Taggart and Hank Rearden. Galt himself remains concealed throughout much of the novel, in a valley by himself, where he unites the most skillful inventors and business leaders under his leadership. Much of the book's third division is given to his broadcast speech, which presents the author's philosophy of Objectivism. ==== Henry "Hank" Rearden ==== Henry (known as "Hank") Rearden is one of the central characters in Atlas Shrugged. He owns the most important steel company in the United States, and invents Rearden Metal, an alloy stronger than steel (with similar properties to stainless steel). He lives in Philadelphia with his wife Lillian, his brother Philip, and his elderly mother. Rearden represents a type of self-made man or prototypical hero, and illustrates Rand's theory of sex in so far as he accepts the traditional view of sexual congress as a subhuman instinct, but responds sexually to Dagny Taggart. ==== Eddie Willers ==== Edwin "Eddie" Willers is the Special Assistant to the Vice-President in Charge of Operations at Taggart Transcontinental. His father and grandfather worked for the Taggarts, and himself likewise. He is completely loyal to Dagny and to Taggart Transcontinental. Willers does not possess the creative ability of Galt's associates, but matches them in moral courage and is capable of appreciating and making use of their creations. After Dagny shifts her attention and loyalty to saving the captive Galt, Willers maintains the railroad until its collapse. ==== Ragnar Danneskjöld ==== One of Galt's first followers, and world-famous as a pirate, who seizes relief ships sent from the United States to the People's States of Europe. He works to ensure that once those espousing Galt's philosophy are restored to their rightful place in society, they have enough capital to rebuild the world. Kept in the background for much of the book, Danneskjöld makes a personal appearance to encourage Rearden to persevere in his increasingly difficult situation, and gives him a bar of gold as compensation for the income taxes he has paid over the last several years. Danneskjöld is married to the actress Kay Ludlow; their relationship is kept hidden from the outside world, which only knows of Ludlow as a retired film star. Considered a misfit by Galt's other adherents, he views his actions as a means to speed the world along in understanding Galt's perspective. According to Barbara Branden, who was closely associated with Rand at the time the book was written, there were sections written describing Danneskjöld's adventures at sea, cut from the final published text. In a 1974 comment at a lecture, Ayn Rand admitted that Danneskjöld's name was a tribute to Victor Hugo's novel, Hans of Iceland, wherein the hero becomes the first of the Counts of Danneskjöld. In the published book, Danneskjöld is always seen through the eyes of others (Dagny Taggart or Hank Rearden), except for a brief paragraph in the very last chapter. === Antagonists === ==== James Taggart ==== The President of Taggart Transcontinental and the book's most important antagonist. Taggart is an expert influence peddler but incapable of making operational decisions on his own. He relies on his sister, Dagny Taggart, to actually run the railroad, but nonetheless opposes her in almost every endeavor because of his various anti-capitalist moral and political beliefs. In a sense, he is the antithesis of Dagny. This contradiction leads to the recurring absurdity of his life: the desire to overcome those on whom his life depends, and the horror that he will succeed at this. In the final chapters of the novel, he suffers a complete mental breakdown upon realizing that he can no longer deceive himself in this respect. ==== Lillian Rearden ==== The unsupportive wife of Hank Rearden, who dislikes his habits and (secretly at first) seeks to ruin Rearden to prove her own value. Lillian achieves this, when she passes information to James Taggart about her husband's affair with his sister. This information is used to persuade Rearden to sign a Gift Certificate which delivers all the property rights of Rearden Metal to others. Lillian thereafter uses James Taggart for sexual satisfaction, until Hank abandons her. ==== Dr. Floyd Ferris ==== Ferris is a biologist who works as "co-ordinator" at the State Science Institute. He uses his position there to deride reason and productive achievement, and publishes a book entitled Why Do You Think You Think? He clashes on several occasions with Hank Rearden, and twice attempts to blackmail Rearden into giving up Rearden Metal. He is also one of the group of looters who tries to get Rearden to agree to the Steel Unification Plan. Ferris hosts the demonstration of the Project X weapon, and is the creator of the Ferris Persuader, a torture machine. When John Galt is captured by the looters, Ferris uses the device on Galt, but it breaks down before extracting the information Ferris wants from Galt. Ferris represents the group which uses brute force on the heroes to achieve the ends of the looters. ==== Dr. Robert Stadler ==== A former professor at Patrick Henry University, and along with colleague Hugh Akston, mentor to Francisco d'Anconia, John Galt and Ragnar Danneskjöld. He has since become a sell-out, one who had great promise but squandered it for social approval, to the detriment of the free. He works at the State Science Institute where all his inventions are perverted for use by the military, including the instrument of his demise: Project X (Xylophone). The character was, in part, modeled on J. Robert Oppenheimer, whom Rand had interviewed for an earlier project, and his part in the creation of nuclear weapons. To his former student Galt, Stadler represents the epitome of human evil, as the "man who knew better" but chose not to act for the good. ==== Wesley Mouch ==== The incompetent and treacherous lobbyist whom Hank Rearden reluctantly employs in Washington, who rises to prominence and authority throughout the novel through trading favours and disloyalty. In return for betraying Hank by helping broker the Equalization of Opportunity Bill (which, by restricting the number of businesses each person may own to one, forces Hank to divest most of his companies), he is given a senior position at the Bureau of Economic Planning and National Resources. Later in the novel he becomes its Top Co-ordinator, a position that eventually becomes Economic Dictator of the country. == Secondary characters == The following secondary characters also appear in the novel. Hugh Akston is identified as "One of the last great advocates of reason." He was a renowned philosopher and the head of the Department of Philosophy at Patrick Henry University, where he taught Francisco d'Anconia, John Galt, and Ragnar Danneskjöld. He was, along with Robert Stadler, a father figure to these three. Akston's name is so hallowed that a young lady, on hearing that Francisco had studied under him, is shocked. She thought he must have been one of those great names from an earlier century. He now works as a cook in a roadside diner, and proves extremely skillful at the job. When Dagny tracks him down, and before she discovers his true identity, he rejects her enthusiastic offer to manage the dining car services for Taggart Transcontinental. He is based on Aristotle. Jeff Allen is a tramp who stows away on a Taggart train during one of Dagny's cross-country trips. Instead of throwing him out, she allows him to ride as her guest. It is from Allen that she learns the full story behind the collapse of the Twentieth Century Motor Company (Rand's extensive metaphor for the inherent flaws of communism), as well as a hint of John Galt's true background. Calvin Atwood is owner of Atwood Light and Power Company and joins Galt's strike. Mayor Bascom is the mayor of Rome, Wisconsin, who reveals part of the history of the Twentieth Century Motor Company. Dr. Blodgett is the scientist who pulls the lever to demonstrate Project X. Orren Boyle is the head of Associated Steel, antithesis of Hank Rearden and a friend of James Taggart. He is an investor in the San Sebastián Mines. He disappears from the story after having a nervous breakdown following the failed 'unification' of the steel industry. Laura Bradford is an actress and Kip Chalmers's mistress. Bill Brent is the chief dispatcher for the Colorado Division of Taggart Transcontinental, who tries to prevent the Taggart Tunnel disaster. Cherryl Brooks is a dime store shopgirl who marries James Taggart after a chance encounter in her store the night the John Galt Line was falsely deemed his greatest success. She marries him thinking he is the heroic person behind Taggart Transcontinental. Cherryl is at first harsh towards Dagny, having believed Jim Taggart's descriptions of his sister, until she questions employees of the railroad. Upon learning that her scorn had been misdirected, Cherryl puts off apologizing to Dagny out of shame until the night before she commits suicide, when she confesses to Dagny that when she married Jim, she thought he had the heroic qualities that she had looked up to - she thought she was marrying someone like Dagny. She eventually commits suicide, unable to live with her worthless husband, and unable to escape. Millie Bush was "a mean, ugly little eight-year-old" girl voted to receive gold braces to straighten her teeth by the Marxist "family" committee who determined how pay was allocated at The Twentieth Century Motor Company. Her teeth are later knocked out by a man denied an allowance by the committee to purchase the things he valued. Emma Chalmers, Kip Chalmers' mother, gains some influence after his death. Known as "Kip's Ma," she starts a soybean-growing project in Louisiana and commandeers thousands of railcars to move the harvest. As a result, the year's wheat crop from Minnesota never reaches the rest of the country, but instead rots in storage; also, the soybean crop is lost, having been reaped too early. Kip Chalmers is a Washington man who has decided to run for election as Legislator from California. On the way to his campaign, the Taggart Transcontinental train that is carrying him encounters a split rail, resulting in the destruction of its diesel engine. His demands lead to a coal-burning steam engine being attached to his train in its stead and used to pull it through an eight-mile tunnel. The result is the suffocation of all passengers and the destruction of the Taggart Tunnel. Dan Conway is the middle-aged president of the Phoenix-Durango railroad. Running a railroad is just about the only thing he knows. When the Anti-dog-eat-dog Rule is used to drive his business out of Colorado, he loses the will to fight, and resigns himself to a quiet life of books and fishing. Ken Danagger owns Danagger Coal in Pennsylvania. He helps Hank Rearden illegally make Rearden Metal, then later decides to quit and join Galt's strike moments before Dagny arrives to try to persuade him otherwise. Quentin Daniels is an enterprising engineer hired by Dagny Taggart to reconstruct John Galt's motor. Partway through this process, Quentin withdraws his effort for the same reasons John Galt himself had. Dagny's pursuit of Quentin leads her to Galt's Gulch. Sebastian d'Anconia was the 16th (or 17th) Century founder of the d'Anconia dynasty. Escaped from Spain because of expressing his opinions too freely and coming in conflict with the Inquisition, leaving behind a palace and his beloved. Started a small mine in South America, which became the beginning of a mining empire and a new fortune (and a new palace). Eventually sent for his beloved who had waited for him many years. He is the role model which Francisco d'Anconia looks to, as Dagny Taggart looks to Nathaniel Taggart. Francisco remarks that their respective ancestors would have liked each other. Balph Eubank is called "the literary leader of the age", despite the fact that no book he has written has sold more than 3,000 copies. He complains that it is disgraceful that artists are treated as peddlers, and that there should be a law limiting the sales of books to 10,000 copies. He is a misogynist who thinks it disgusting that Dagny Taggart is a railroad vice-president. The Fishwife is one of the strikers, who earns her living by providing the fish for Hammond’s grocery market; she is described as having "dark, disheveled hair and large eyes", and is a writer. Galt says she "wouldn't be published outside. She believes that when one deals with words, one deals with the mind." According to Barbara Branden in her book The Passion of Ayn Rand, "The Fishwife is Ayn's Hitchcock-like appearance in Atlas Shrugged." So says too Leonard Peikoff. Lawrence Hammond runs Hammond Cars in Colorado, one of the few companies in existence that still produces top-quality vehicles. He eventually quits and joins the strike. Richard Halley is Dagny Taggart's favorite composer, who mysteriously disappeared after the evening of his greatest triumph. Halley spent years as a struggling and unappreciated composer. At age 24, his opera Phaethon was performed for the first time, to an audience who booed and heckled it. After 19 years, Phaethon was performed again, but this time it was received to the greatest ovation the opera house had ever heard. The following day, Halley retired, sold the rights to his music, and disappeared. It is later revealed that he has joined the strike and settled in Galt's Gulch. Mrs. William Hastings is the widow of the chief engineer at the Twentieth Century Motor Company. Her husband quit shortly after Galt did and joined the strike some years later. Her lead allows Dagny to find Hugh Akston. Dr. Thomas Hendricks is a famous brain surgeon who developed a new method of preventing strokes. He joined Galt's strike when the American medical system was put under government control. Tinky Holloway is one of the "looters" and is frequently referred to and quoted by other characters in the story, but he has only one major appearance: during the Washington meeting with Hank Rearden. Lee Hunsacker is in charge of a company called Amalgamated Service when takes over the Twentieth Century Motor Company. He files a lawsuit that eventually leads to Midas Mulligan and Judge Narragansett joining the strike. A failed businessman, he laments constantly that no-one ever gave him a chance. Gwen Ives is Hank Rearden's secretary. Owen Kellogg is Assistant to the Manager of the Taggart Terminal in New York. He catches Dagny Taggart's eye as one of the few competent men on staff. After seeing the sorry state of the Ohio Division, she decides to make him its new Superintendent. However, as soon as she returns to New York, Kellogg informs her that he is quitting his job. Owen Kellogg eventually reaches, and settles in, Galt's Gulch. Gilbert Keith-Worthing is a British novelist of erstwhile fame, now neglected but still considered a "walking classic". Rand introduces him only for a few pages as a guest of Kip Chalmers ("for no reason that either of them could discover") to then implicitly have him asphyxiated in the Tunnel catastrophe, after giving some statements. Fred Kinnan is a labor leader and member of the looter cabal. Unlike the others, however, Kinnan is straightforward and honest about his purpose. Kinnan is the only one to openly state the true motivations of himself and his fellow conspirators. At the end of Galt's three-hour speech, he expresses admiration for the man, as he says what he means. Despite this, Kinnan admits that he is one of the people Galt is out to destroy. Paul Larkin is an unsuccessful, middle-aged businessman, a friend of the Rearden family. He meets with the other Looters to work out a plan to bring Rearden down. James Taggart knows he is friends with Hank Rearden and challenges his loyalty, and Larkin assures Taggart that he will go along with them. Eugene Lawson heads the Community Bank of Madison, then gets a job with the government when it his bank goes bankrupt. One of the looter's cabal, he is a collectivist who abhors production and money-making. Mort Liddy is a hack composer who writes trite scores for movies and modern symphonies to which no one listens. He believes melody is a primitive vulgarity. He is one of Lillian Rearden's friends and a member of the cultural elite. Clifton Locey is a friend of Jim Taggart who takes the position of vice-president of operation when Dagny Taggart quits. Pat Logan is the engineer on the first run of the John Galt Line. He later strikes. Kay Ludlow is a beautiful actress and the wife of Ragnar Danneskjöld. Dick McNamara is a contractor who finished the San Sebastian Line. Dagny Taggart plans to hire him to lay the new Rearden Metal track for the Rio Norte Line, but before she does so, he mysteriously disappears. She later discovers that he has joined the strike and settled in Galt's Gulch. Cuffy Meigs is the Director of Unification for the railroad business. He carries a pistol and a lucky rabbit's foot, and he dresses in a military uniform, and has been described as "impervious to thought". Meigs seizes control of Project X and accidentally destroys it, demolishing the country's last railroad bridge across the Mississippi River and killing himself, his men, and Dr. Stadler. Dave Mitchum is a state-hired superintendent of the Colorado Division of Taggart Transcontinental. He is partially responsible for the Taggart Tunnel disaster. Chick Morrison holds the position of "Morale Conditioner" in the government. He quits when society begins to collapse and flees to a stronghold in Tennessee. His fellow looters consider it unlikely that he will survive. Horace Bussby Mowen is the president of the Amalgamated Switch and Signal Company, Inc. of Connecticut. He is a businessman who sees nothing wrong with the moral code that is destroying society and would never dream of saying he is in business for any reason other than the good of society. Dagny Taggart hires Mowen to produce switches made of Rearden Metal. He is reluctant to build anything with this unproven technology, and has to be cajoled into accepting the contract. When pressured by public opinion, he discontinues production of the switches, forcing Dagny to find an alternative source. Midas Mulligan is a wealthy banker who mysteriously disappeared in protest after he was given a court order to lend money to an incompetent applicant. When the order came down, he liquidated his entire business, paid off his depositors, and joined Galt's strike. He is the legal owner of the land where Galt's Gulch is located. Mulligan's birth name was Michael, but he had it legally changed after a news article called him "Midas" in a derogatory fashion, which Mulligan took as a compliment. Judge Narragansett is an American jurist who ruled in favor of Midas Mulligan during the case brought against him by the incompetent loan applicant. When Narragansett's ruling was reversed on appeal, he retired and joined the strike. At the end of the novel, he is seen editing the United States Constitution, crossing out the contradicting amendments of it and adding an amendment to prohibit Congress from passing laws that restrain freedom of trade. Ben Nealy is a railroad contractor whom Dagny Taggart hires to replace the track on the Rio Norte Line with Rearden Metal. Nealy is incompetent, but Dagny can find no one better in all the country. Nealy believes that anything can get done with enough muscle power. He sees no role for intelligence in human achievement. He relies on Dagny and Ellis Wyatt to run things, and resents them for doing it, because it appears to him like they are just bossing people around. Ted Nielsen is the head of Nielsen Motors. He eventually goes on strike, along with most of the other industrialist "producer" types, by closing his motor factory. Dagny later finds him when she visits Galt's Gulch for the first time. Betty Pope is a wealthy socialite who is having a meaningless sexual affair with James Taggart. She is deliberately crude in a way that casts ridicule on her high social position. Dr. Potter holds some undefined position with the State Science Institute. He is sent to try to obtain the rights to Rearden Metal. Dr. Simon Pritchett is the prestigious head of the Department of Philosophy at Patrick Henry University and is considered the leading philosopher of the age. He believes that man is nothing but a collection of chemicals, reason is a superstition, it is futile to seek meaning in life, and the duty of a philosopher is to show that nothing can be understood. Rearden's mother, whose name is not mentioned, lives with Rearden at his home in Philadelphia. She is involved in charity work, and berates Rearden whenever she can. She dotes on her weak son Philip Rearden. Philip Rearden is the younger brother of Hank Rearden. He lives in his brother's home in Philadelphia and is completely dependent on him. He is resentful of his brother's charity. Dwight Sanders owns Sanders Aircraft, a producer of high-quality airplanes, and joins the strike. Bertram Scudder is an editorial writer for the magazine The Future. He typically bashes business and businessmen, but he never says anything specific in his articles, relying on innuendo, sneers, and denunciation. He wrote a hatchet job on Hank Rearden called The Octopus. He is also vocal in support of the Equalization of Opportunity Bill. Scudder claims that the most important thing in life is "brother love" but seems to have nothing but hatred for those around him. He loses his job after Dagny Taggart reveals her affair with Hank Rearden over air on his radio show. Claude Slagenhop is president of political organization Friends of Global Progress and one of Lillian Rearden's friends. He believes that ideas are just air, that this is no time for talk, but for action. Global Progress is a sponsor of the Equalization of Opportunity Bill. Gerald and Ivy Starnes are the two surviving children of Jed Starnes, the founder of the Twentieth Century Motor Company. Together with their since-deceased brother Eric, they instituted a communistic payment-and-benefits program that drove the company into bankruptcy. Gerald, a dying alcoholic, and Ivy, a pseudo-Buddhist ascetic, continue to insist that the plan was perfect and that the failure of their father's company was entirely due to the workers. Eric was a weak, attention-seeking man with a pathological desire to be loved. He committed suicide after the woman he loved married another man. Gerald claims that he always acted for the good of the employees, but he was vain and incompetent and often threw lavish parties using company funds. Ivy, on the other hand, is described as a sadist who relishes seeing others in poverty, but who has no desire for wealth of her own. Andrew Stockton runs the Stockton Foundry in Stockton, Colorado. When he joins the strike, he opens a foundry in Galt's Gulch. Nathaniel "Nat" Taggart was the founder of Taggart Transcontinental. He built his railroad without any government handouts, and ran the business for no other reason than to turn a profit. He began as a penniless adventurer and ended up as one of the wealthiest men in the country. He never earned money by force or fraud (except for bribing government officials and throwing an opponent down a flight of stairs), and never apologized for becoming wealthy and successful. He was one of the most hated men of his time. Dagny is often inspired by looking at a statue of Nat Taggart at the railroad headquarters, and draws a dollar sign on its base as a signal to Francisco when she is ready to join Galt's strike. It is suspected that he is modeled after James Jerome Hill, builder of the Great Northern Railroad. Mr. Thompson is the "Head of the State" for the United States. He is not particularly intelligent and has a very undistinguished look. He knows politics, however, and is a master of public relations and back-room deals. Rand's notes indicate that she modeled him on President Harry S. Truman, and that she deliberately decided not to call him "President of the United States" as this title has "honorable connotations" which the character does not deserve. Lester Tuck is the press agent for Kip Chalmers. Clem Weatherby is a government representative on the board of directors of Taggart Transcontinental. Dagny considers him the least bad of the government representatives, since he does have some real knowledge on the running of trains. She notices, however, that he is the least appreciated by his own bosses. The Wet Nurse (Tony) is a young bureaucrat sent by the government to watch over Rearden’s mills. Though he starts out as a cynical follower of the looters’ code, his experience at the mills transforms him, and he comes to respect and admire the producers. He is shot attempting to inform Hank Rearden about a government plot, but does succeed in warning Rearden just before he dies. Ellis Wyatt is the head of Wyatt Oil. He has almost single-handedly revived the economy of Colorado by discovering a new process for extracting more oil from what were thought to be exhausted oil wells. When first introduced, he is aggressive towards Dagny, whom he does not yet know and whom he blames for what are, in fact, her brother's policies which directly threaten his business. When the government passes laws and decrees which make it impossible for him to continue, he sets all his oil wells on fire, leaving a jeering note: "I am leaving it as I found it. Take over. It's yours." One particular burning well that resists all efforts to extinguish it becomes known as "Wyatt's Torch". Later Dagny meets him in Galt's Gulch. == Notes == == References == Gladstein, Mimi Reisel (1999). The New Ayn Rand Companion. Westport, Connecticut: Greenwood Press. ISBN 0-313-30321-5.

### Instruction: retrieve labels for this: Anthropology is the study of humans and human behaviour and societies in the past and present. Social anthropology and cultural anthropology study the norms and values of societies. Linguistic anthropology studies how language affects social life. Biological or physical anthropology studies the biological development of humans. Archaeology, which studies past human cultures through investigation of physical evidence, is thought of as a branch of anthropology in the United States, while in Europe, it is viewed as a discipline in its own right or grouped under other related disciplines, such as history. == Origin and development of the term == The abstract noun anthropology is first attested in reference to history. Its present use first appeared in Renaissance Germany in the works of Magnus Hundt and Otto Casmann. Their New Latin anthropologia derived from the combining forms of the Greek words ánthrōpos (ἄνθρωπος, "human") and lógos (λόγος, "study"). (Its adjectival form appeared in the works of Aristotle.) It began to be used in English, possibly via French Anthropologie, by the early 18th century. === Through the 19th century === In 1647, the Bartholins, founders of the University of Copenhagen, defined l'anthropologie as follows: Anthropology, that is to say the science that treats of man, is divided ordinarily and with reason into Anatomy, which considers the body and the parts, and Psychology, which speaks of the soul. Sporadic use of the term for some of the subject matter occurred subsequently, such as the use by Étienne Serres in 1839 to describe the natural history, or paleontology, of man, based on comparative anatomy, and the creation of a chair in anthropology and ethnography in 1850 at the National Museum of Natural History (France) by Jean Louis Armand de Quatrefages de Bréau. Various short-lived organizations of anthropologists had already been formed. The Société Ethnologique de Paris, the first to use Ethnology, was formed in 1839. Its members were primarily anti-slavery activists. When slavery was abolished in France in 1848 the Société was abandoned. Meanwhile, the Ethnological Society of New York, currently the American Ethnological Society, was founded on its model in 1842, as well as the Ethnological Society of London in 1843, a break-away group of the Aborigines' Protection Society. These anthropologists of the times were liberal, anti-slavery, and pro-human-rights activists. They maintained international connections. Anthropology and many other current fields are the intellectual results of the comparative methods developed in the earlier 19th century. Theorists in such diverse fields as anatomy, linguistics, and Ethnology, making feature-by-feature comparisons of their subject matters, were beginning to suspect that similarities between animals, languages, and folkways were the result of processes or laws unknown to them then. For them, the publication of Charles Darwin's On the Origin of Species was the epiphany of everything they had begun to suspect. Darwin himself arrived at his conclusions through comparison of species he had seen in agronomy and in the wild. Darwin and Wallace unveiled evolution in the late 1850s. There was an immediate rush to bring it into the social sciences. Paul Broca in Paris was in the process of breaking away from the Société de biologie to form the first of the explicitly anthropological societies, the Société d'Anthropologie de Paris, meeting for the first time in Paris in 1859. When he read Darwin, he became an immediate convert to Transformisme, as the French called evolutionism. His definition now became "the study of the human group, considered as a whole, in its details, and in relation to the rest of nature".Broca, being what today would be called a neurosurgeon, had taken an interest in the pathology of speech. He wanted to localize the difference between man and the other animals, which appeared to reside in speech. He discovered the speech center of the human brain, today called Broca's area after him. His interest was mainly in Biological anthropology, but a German philosopher specializing in psychology, Theodor Waitz, took up the theme of general and social anthropology in his six-volume work, entitled Die Anthropologie der Naturvölker, 1859–1864. The title was soon translated as "The Anthropology of Primitive Peoples". The last two volumes were published posthumously. Waitz defined anthropology as "the science of the nature of man". By nature he meant matter animated by "the Divine breath"; i.e., he was an animist. Following Broca's lead, Waitz points out that anthropology is a new field, which would gather material from other fields, but would differ from them in the use of comparative anatomy, physiology, and psychology to differentiate man from "the animals nearest to him". He stresses that the data of comparison must be empirical, gathered by experimentation. The history of civilization, as well as ethnology, are to be brought into the comparison. It is to be presumed fundamentally that the species, man, is a unity, and that "the same laws of thought are applicable to all men".Waitz was influential among the British ethnologists. In 1863 the explorer Richard Francis Burton and the speech therapist James Hunt broke away from the Ethnological Society of London to form the Anthropological Society of London, which henceforward would follow the path of the new anthropology rather than just ethnology. It was the 2nd society dedicated to general anthropology in existence. Representatives from the French Société were present, though not Broca. In his keynote address, printed in the first volume of its new publication, The Anthropological Review, Hunt stressed the work of Waitz, adopting his definitions as a standard. Among the first associates were the young Edward Burnett Tylor, inventor of cultural anthropology, and his brother Alfred Tylor, a geologist. Previously Edward had referred to himself as an ethnologist; subsequently, an anthropologist. Similar organizations in other countries followed: The Anthropological Society of Madrid (1865), the American Anthropological Association in 1902, the Anthropological Society of Vienna (1870), the Italian Society of Anthropology and Ethnology (1871), and many others subsequently. The majority of these were evolutionist. One notable exception was the Berlin Society for Anthropology, Ethnology, and Prehistory (1869) founded by Rudolph Virchow, known for his vituperative attacks on the evolutionists. Not religious himself, he insisted that Darwin's conclusions lacked empirical foundation. During the last three decades of the 19th century, a proliferation of anthropological societies and associations occurred, most independent, most publishing their own journals, and all international in membership and association. The major theorists belonged to these organizations. They supported the gradual osmosis of anthropology curricula into the major institutions of higher learning. By 1898 the American Association for the Advancement of Science was able to report that 48 educational institutions in 13 countries had some curriculum in anthropology. None of the 75 faculty members were under a department named anthropology. === 20th and 21st centuries === This meagre statistic expanded in the 20th century to comprise anthropology departments in the majority of the world's higher educational institutions, many thousands in number. Anthropology has diversified from a few major subdivisions to dozens more. Practical Anthropology, the use of anthropological knowledge and technique to solve specific problems, has arrived; for example, the presence of buried victims might stimulate the use of a forensic archaeologist to recreate the final scene. The organization has reached global level. For example, the World Council of Anthropological Associations (WCAA), "a network of national, regional and international associations that aims to promote worldwide communication and cooperation in anthropology", currently contains members from about three dozen nations.Since the work of Franz Boas and Bronisław Malinowski in the late 19th and early 20th centuries, social anthropology in Great Britain and cultural anthropology in the US have been distinguished from other social sciences by its emphasis on cross-cultural comparisons, long-term in-depth examination of context, and the importance it places on participant-observation or experiential immersion in the area of research. Cultural anthropology, in particular, has emphasized cultural relativism, holism, and the use of findings to frame cultural critiques. This has been particularly prominent in the United States, from Boas' arguments against 19th-century racial ideology, through Margaret Mead's advocacy for gender equality and sexual liberation, to current criticisms of post-colonial oppression and promotion of multiculturalism. Ethnography is one of its primary research designs as well as the text that is generated from anthropological fieldwork.In Great Britain and the Commonwealth countries, the British tradition of social anthropology tends to dominate. In the United States, anthropology has traditionally been divided into the four field approach developed by Franz Boas in the early 20th century: biological or physical anthropology; social, cultural, or sociocultural anthropology; and archaeology; plus anthropological linguistics. These fields frequently overlap but tend to use different methodologies and techniques. European countries with overseas colonies tended to practice more ethnology (a term coined and defined by Adam F. Kollár in 1783). It is sometimes referred to as sociocultural anthropology in the parts of the world that were influenced by the European tradition. == Fields == Anthropology is a global discipline involving humanities, social sciences and natural sciences. Anthropology builds upon knowledge from natural sciences, including the discoveries about the origin and evolution of Homo sapiens, human physical traits, human behavior, the variations among different groups of humans, how the evolutionary past of Homo sapiens has influenced its social organization and culture, and from social sciences, including the organization of human social and cultural relations, institutions, social conflicts, etc. Early anthropology originated in Classical Greece and Persia and studied and tried to understand observable cultural diversity. As such, anthropology has been central in the development of several new (late 20th century) interdisciplinary fields such as cognitive science, global studies, and various ethnic studies. According to Clifford Geertz, "anthropology is perhaps the last of the great nineteenth-century conglomerate disciplines still for the most part organizationally intact. Long after natural history, moral philosophy, philology, and political economy have dissolved into their specialized successors, it has remained a diffuse assemblage of ethnology, human biology, comparative linguistics, and prehistory, held together mainly by the vested interests, sunk costs, and administrative habits of academia, and by a romantic image of comprehensive scholarship." Sociocultural anthropology has been heavily influenced by structuralist and postmodern theories, as well as a shift toward the analysis of modern societies. During the 1970s and 1990s, there was an epistemological shift away from the positivist traditions that had largely informed the discipline. During this shift, enduring questions about the nature and production of knowledge came to occupy a central place in cultural and social anthropology. In contrast, archaeology and biological anthropology remained largely positivist. Due to this difference in epistemology, the four sub-fields of anthropology have lacked cohesion over the last several decades. === Sociocultural === Sociocultural anthropology draws together the principle axes of cultural anthropology and social anthropology. Cultural anthropology is the comparative study of the manifold ways in which people make sense of the world around them, while social anthropology is the study of the relationships among individuals and groups. Cultural anthropology is more related to philosophy, literature and the arts (how one's culture affects the experience for self and group, contributing to a more complete understanding of the people's knowledge, customs, and institutions), while social anthropology is more related to sociology and history. In that, it helps develop an understanding of social structures, typically of others and other populations (such as minorities, subgroups, dissidents, etc.). There is no hard-and-fast distinction between them, and these categories overlap to a considerable degree. Inquiry in sociocultural anthropology is guided in part by cultural relativism, the attempt to understand other societies in terms of their own cultural symbols and values. Accepting other cultures in their own terms moderates reductionism in cross-cultural comparison. This project is often accommodated in the field of ethnography. Ethnography can refer to both a methodology and the product of ethnographic research, i.e. an ethnographic monograph. As a methodology, ethnography is based upon long-term fieldwork within a community or other research site. Participant observation is one of the foundational methods of social and cultural anthropology. Ethnology involves the systematic comparison of different cultures. The process of participant-observation can be especially helpful to understanding a culture from an emic (conceptual, vs. etic, or technical) point of view. The study of kinship and social organization is a central focus of sociocultural anthropology, as kinship is a human universal. Sociocultural anthropology also covers economic and political organization, law and conflict resolution, patterns of consumption and exchange, material culture, technology, infrastructure, gender relations, ethnicity, childrearing and socialization, religion, myth, symbols, values, etiquette, worldview, sports, music, nutrition, recreation, games, food, festivals, and language (which is also the object of study in linguistic anthropology). Comparison across cultures is a key element of method in sociocultural anthropology, including the industrialized (and de-industrialized) West. Cultures in the Standard Cross-Cultural Sample (SCCS) of world societies are: === Biological === Biological Anthropology and Physical Anthropology are synonymous terms to describe anthropological research focused on the study of humans and non-human primates in their biological, evolutionary, and demographic dimensions. It examines the biological and social factors that have affected the evolution of humans and other primates, and that generate, maintain or change contemporary genetic and physiological variation. === Archaeological === Archaeology is the study of the human past through its material remains. Artifacts, faunal remains, and human altered landscapes are evidence of the cultural and material lives of past societies. Archaeologists examine this material remains in order to deduce patterns of past human behavior and cultural practices. Ethnoarchaeology is a type of archaeology that studies the practices and material remain of living human groups in order to gain a better understanding of the evidence left behind by past human groups, who are presumed to have lived in similar ways. === Linguistic === Linguistic anthropology (not to be confused with anthropological linguistics) seeks to understand the processes of human communications, verbal and non-verbal, variation in language across time and space, the social uses of language, and the relationship between language and culture. It is the branch of anthropology that brings linguistic methods to bear on anthropological problems, linking the analysis of linguistic forms and processes to the interpretation of sociocultural processes. Linguistic anthropologists often draw on related fields including sociolinguistics, pragmatics, cognitive linguistics, semiotics, discourse analysis, and narrative analysis. == Key topics by field: sociocultural == === Art, media, music, dance and film === ==== Art ==== One of the central problems in the anthropology of art concerns the universality of 'art' as a cultural phenomenon. Several anthropologists have noted that the Western categories of 'painting', 'sculpture', or 'literature', conceived as independent artistic activities, do not exist, or exist in a significantly different form, in most non-Western contexts. To surmount this difficulty, anthropologists of art have focused on formal features in objects which, without exclusively being 'artistic', have certain evident 'aesthetic' qualities. Boas' Primitive Art, Claude Lévi-Strauss' The Way of the Masks (1982) or Geertz's 'Art as Cultural System' (1983) are some examples in this trend to transform the anthropology of 'art' into an anthropology of culturally specific 'aesthetics'. ==== Media ==== Media anthropology (also known as the anthropology of media or mass media) emphasizes ethnographic studies as a means of understanding producers, audiences, and other cultural and social aspects of mass media. The types of ethnographic contexts explored range from contexts of media production (e.g., ethnographies of newsrooms in newspapers, journalists in the field, film production) to contexts of media reception, following audiences in their everyday responses to media. Other types include cyber anthropology, a relatively new area of internet research, as well as ethnographies of other areas of research which happen to involve media, such as development work, social movements, or health education. This is in addition to many classic ethnographic contexts, where media such as radio, the press, new media, and television have started to make their presences felt since the early 1990s. ==== Music ==== Ethnomusicology is an academic field encompassing various approaches to the study of music (broadly defined), that emphasize its cultural, social, material, cognitive, biological, and other dimensions or contexts instead of or in addition to its isolated sound component or any particular repertoire. ==== Visual ==== Visual anthropology is concerned, in part, with the study and production of ethnographic photography, film and, since the mid-1990s, new media. While the term is sometimes used interchangeably with ethnographic film, visual anthropology also encompasses the anthropological study of visual representation, including areas such as performance, museums, art, and the production and reception of mass media. Visual representations from all cultures, such as sandpaintings, tattoos, sculptures and reliefs, cave paintings, scrimshaw, jewelry, hieroglyphics, paintings, and photographs are included in the focus of visual anthropology. === Economic, political economic, applied and development === ==== Economic ==== Economic anthropology attempts to explain human economic behavior in its widest historic, geographic and cultural scope. It has a complex relationship with the discipline of economics, of which it is highly critical. Its origins as a sub-field of anthropology begin with the Polish-British founder of Anthropology, Bronisław Malinowski, and his French compatriot, Marcel Mauss, on the nature of gift-giving exchange (or reciprocity) as an alternative to market exchange. Economic Anthropology remains, for the most part, focused upon exchange. The school of thought derived from Marx and known as Political Economy focuses on production, in contrast. Economic Anthropologists have abandoned the primitivist niche they were relegated to by economists, and have now turned to examine corporations, banks, and the global financial system from an anthropological perspective. ==== Political economy ==== Political economy in anthropology is the application of the theories and methods of Historical Materialism to the traditional concerns of anthropology, including, but not limited to, non-capitalist societies. Political Economy introduced questions of history and colonialism to ahistorical anthropological theories of social structure and culture. Three main areas of interest rapidly developed. The first of these areas was concerned with the "pre-capitalist" societies that were subject to evolutionary "tribal" stereotypes. Sahlin's work on hunter-gatherers as the 'original affluent society' did much to dissipate that image. The second area was concerned with the vast majority of the world's population at the time, the peasantry, many of whom were involved in complex revolutionary wars such as in Vietnam. The third area was on colonialism, imperialism, and the creation of the capitalist world-system. More recently, these Political Economists have more directly addressed issues of industrial (and post-industrial) capitalism around the world. ==== Applied ==== Applied Anthropology refers to the application of the method and theory of anthropology to the analysis and solution of practical problems. It is a "complex of related, research-based, instrumental methods which produce change or stability in specific cultural systems through the provision of data, initiation of direct action, and/or the formulation of policy". More simply, applied anthropology is the practical side of anthropological research; it includes researcher involvement and activism within the participating community. It is closely related to Development anthropology (distinct from the more critical Anthropology of development). ==== Development ==== Anthropology of development tends to view development from a critical perspective. The kind of issues addressed and implications for the approach simply involve pondering why, if a key development goal is to alleviate poverty, is poverty increasing? Why is there such a gap between plans and outcomes? Why are those working in development so willing to disregard history and the lessons it might offer? Why is development so externally driven rather than having an internal basis? In short, why does so much planned development fail? === Kinship, feminism, gender and sexuality === ==== Kinship ==== Kinship can refer both to the study of the patterns of social relationships in one or more human cultures, or it can refer to the patterns of social relationships themselves. Over its history, anthropology has developed a number of related concepts and terms, such as "descent", "descent groups", "lineages", "affines", "cognates", and even "fictive kinship". Broadly, kinship patterns may be considered to include people related both by descent (one's social relations during development), and also relatives by marriage. ==== Feminist ==== Feminist anthropology is a four field approach to anthropology (archeological, biological, cultural, linguistic) that seeks to reduce male bias in research findings, anthropological hiring practices, and the scholarly production of knowledge. Anthropology engages often with feminists from non-Western traditions, whose perspectives and experiences can differ from those of white European and American feminists. Historically, such 'peripheral' perspectives have sometimes been marginalized and regarded as less valid or important than knowledge from the western world. Feminist anthropologists have claimed that their research helps to correct this systematic bias in mainstream feminist theory. Feminist anthropologists are centrally concerned with the construction of gender across societies. Feminist anthropology is inclusive of birth anthropology as a specialization. The first African-American female anthropologist and Caribbeanist are said to be Vera Mae Green who studied ethnic and family relations in the Caribbean as well as the United States, and thereby tried to improve the way black life, experiences, and culture were studied. === Medical, nutritional, psychological, cognitive and transpersonal === ==== Medical ==== Medical anthropology is an interdisciplinary field which studies "human health and disease, health care systems, and biocultural adaptation". It is believed that William Caudell was the first to discover the field of medical anthropology. Currently, research in medical anthropology is one of the main growth areas in the field of anthropology as a whole. It focuses on the following six basic fields: the development of systems of medical knowledge and medical care the patient-physician relationship the integration of alternative medical systems in culturally diverse environments the interaction of social, environmental and biological factors which influence health and illness both in the individual and the community as a whole the critical analysis of interaction between psychiatric services and migrant populations ("critical ethnopsychiatry": Beneduce 2004, 2007) the impact of biomedicine and biomedical technologies in non-Western settings Other subjects that have become central to medical anthropology worldwide are violence and social suffering (Farmer, 1999, 2003; Beneduce, 2010) as well as other issues that involve physical and psychological harm and suffering that are not a result of illness. On the other hand, there are fields that intersect with medical anthropology in terms of research methodology and theoretical production, such as cultural psychiatry and transcultural psychiatry or ethnopsychiatry. ==== Nutritional ==== Nutritional anthropology is a synthetic concept that deals with the interplay between economic systems, nutritional status and food security, and how changes in the former affect the latter. If economic and environmental changes in a community affect access to food, food security, and dietary health, then this interplay between culture and biology is in turn connected to broader historical and economic trends associated with globalization. Nutritional status affects overall health status, work performance potential, and the overall potential for economic development (either in terms of human development or traditional western models) for any given group of people. ==== Psychological ==== Psychological anthropology is an interdisciplinary subfield of anthropology that studies the interaction of cultural and mental processes. This subfield tends to focus on ways in which humans' development and enculturation within a particular cultural group—with its own history, language, practices, and conceptual categories—shape processes of human cognition, emotion, perception, motivation, and mental health. It also examines how the understanding of cognition, emotion, motivation, and similar psychological processes inform or constrain our models of cultural and social processes. ==== Cognitive ==== Cognitive anthropology seeks to explain patterns of shared knowledge, cultural innovation, and transmission over time and space using the methods and theories of the cognitive sciences (especially experimental psychology and evolutionary biology) often through close collaboration with historians, ethnographers, archaeologists, linguists, musicologists and other specialists engaged in the description and interpretation of cultural forms. Cognitive anthropology is concerned with what people from different groups know and how that implicit knowledge changes the way people perceive and relate to the world around them. ==== Transpersonal ==== Transpersonal anthropology studies the relationship between altered states of consciousness and culture. As with transpersonal psychology, the field is much concerned with altered states of consciousness (ASC) and transpersonal experience. However, the field differs from mainstream transpersonal psychology in taking more cognizance of cross-cultural issues—for instance, the roles of myth, ritual, diet, and texts in evoking and interpreting extraordinary experiences. === Political and legal === ==== Political ==== Political anthropology concerns the structure of political systems, looked at from the basis of the structure of societies. Political anthropology developed as a discipline concerned primarily with politics in stateless societies, a new development started from the 1960s, and is still unfolding: anthropologists started increasingly to study more "complex" social settings in which the presence of states, bureaucracies and markets entered both ethnographic accounts and analysis of local phenomena. The turn towards complex societies meant that political themes were taken up at two main levels. First of all, anthropologists continued to study political organization and political phenomena that lay outside the state-regulated sphere (as in patron-client relations or tribal political organization). Second of all, anthropologists slowly started to develop a disciplinary concern with states and their institutions (and on the relationship between formal and informal political institutions). An anthropology of the state developed, and it is a most thriving field today. Geertz' comparative work on "Negara", the Balinese state is an early, famous example. ==== Legal ==== Legal anthropology or anthropology of law specializes in "the cross-cultural study of social ordering". Earlier legal anthropological research often focused more narrowly on conflict management, crime, sanctions, or formal regulation. More recent applications include issues such as human rights, legal pluralism, and political uprisings. ==== Public ==== Public Anthropology was created by Robert Borofsky, a professor at Hawaii Pacific University, to "demonstrate the ability of anthropology and anthropologists to effectively address problems beyond the discipline – illuminating larger social issues of our times as well as encouraging broad, public conversations about them with the explicit goal of fostering social change" (Borofsky 2004). === Nature, science and technology === ==== Cyborg ==== Cyborg anthropology originated as a sub-focus group within the American Anthropological Association's annual meeting in 1993. The sub-group was very closely related to STS and the Society for the Social Studies of Science. Donna Haraway's 1985 Cyborg Manifesto could be considered the founding document of cyborg anthropology by first exploring the philosophical and sociological ramifications of the term. Cyborg anthropology studies humankind and its relations with the technological systems it has built, specifically modern technological systems that have reflexively shaped notions of what it means to be human beings. ==== Digital ==== Digital anthropology is the study of the relationship between humans and digital-era technology, and extends to various areas where anthropology and technology intersect. It is sometimes grouped with sociocultural anthropology, and sometimes considered part of material culture. The field is new, and thus has a variety of names with a variety of emphases. These include techno-anthropology, digital ethnography, cyberanthropology, and virtual anthropology. ==== Ecological ==== Ecological anthropology is defined as the "study of cultural adaptations to environments". The sub-field is also defined as, "the study of relationships between a population of humans and their biophysical environment". The focus of its research concerns "how cultural beliefs and practices helped human populations adapt to their environments, and how their environment across space and time. The contemporary perspective of environmental anthropology, and arguably at least the backdrop, if not the focus of most of the ethnographies and cultural fieldworks of today, is political ecology. Many characterize this new perspective as more informed with culture, politics and power, globalization, localized issues, century anthropology and more. The focus and data interpretation is often used for arguments for/against or creation of policy, and to prevent corporate exploitation and damage of land. Often, the observer has become an active part of the struggle either directly (organizing, participation) or indirectly (articles, documentaries, books, ethnographies). Such is the case with environmental justice advocate Melissa Checker and her relationship with the people of Hyde Park. === Historical === Ethnohistory is the study of ethnographic cultures and indigenous customs by examining historical records. It is also the study of the history of various ethnic groups that may or may not exist today. Ethnohistory uses both historical and ethnographic data as its foundation. Its historical methods and materials go beyond the standard use of documents and manuscripts. Practitioners recognize the utility of such source material as maps, music, paintings, photography, folklore, oral tradition, site exploration, archaeological materials, museum collections, enduring customs, language, and place names. === Religion === The anthropology of religion involves the study of religious institutions in relation to other social institutions, and the comparison of religious beliefs and practices across cultures. Modern anthropology assumes that there is complete continuity between magical thinking and religion, and that every religion is a cultural product, created by the human community that worships it. === Urban === Urban anthropology is concerned with issues of urbanization, poverty, and neoliberalism. Ulf Hannerz quotes a 1960s remark that traditional anthropologists were "a notoriously agoraphobic lot, anti-urban by definition". Various social processes in the Western World as well as in the "Third World" (the latter being the habitual focus of attention of anthropologists) brought the attention of "specialists in 'other cultures'" closer to their homes. There are two main approaches to urban anthropology: examining the types of cities or examining the social issues within the cities. These two methods are overlapping and dependent of each other. By defining different types of cities, one would use social factors as well as economic and political factors to categorize the cities. By directly looking at the different social issues, one would also be studying how they affect the dynamic of the city. == Key topics by field: archaeological and biological == === Anthrozoology === Anthrozoology (also known as "human–animal studies") is the study of interaction between living things. It is a burgeoning interdisciplinary field that overlaps with a number of other disciplines, including anthropology, ethology, medicine, psychology, veterinary medicine and zoology. A major focus of anthrozoologic research is the quantifying of the positive effects of human-animal relationships on either party and the study of their interactions. It includes scholars from a diverse range of fields, including anthropology, sociology, biology, and philosophy. === Biocultural === Biocultural anthropology is the scientific exploration of the relationships between human biology and culture. Physical anthropologists throughout the first half of the 20th century viewed this relationship from a racial perspective; that is, from the assumption that typological human biological differences lead to cultural differences. After World War II the emphasis began to shift toward an effort to explore the role culture plays in shaping human biology. === Evolutionary === Evolutionary anthropology is the interdisciplinary study of the evolution of human physiology and human behaviour and the relation between hominins and non-hominin primates. Evolutionary anthropology is based in natural science and social science, combining the human development with socioeconomic factors. Evolutionary anthropology is concerned with both biological and cultural evolution of humans, past and present. It is based on a scientific approach, and brings together fields such as archaeology, behavioral ecology, psychology, primatology, and genetics. It is a dynamic and interdisciplinary field, drawing on many lines of evidence to understand the human experience, past and present. === Forensic === Forensic anthropology is the application of the science of physical anthropology and human osteology in a legal setting, most often in criminal cases where the victim's remains are in the advanced stages of decomposition. A forensic anthropologist can assist in the identification of deceased individuals whose remains are decomposed, burned, mutilated or otherwise unrecognizable. The adjective "forensic" refers to the application of this subfield of science to a court of law. === Palaeoanthropology === Paleoanthropology combines the disciplines of paleontology and physical anthropology. It is the study of ancient humans, as found in fossil hominid evidence such as petrifacted bones and footprints. == Organizations == Contemporary anthropology is an established science with academic departments at most universities and colleges. The single largest organization of Anthropologists is the American Anthropological Association (AAA), which was founded in 1903. Membership is made up of anthropologists from around the globe.In 1989, a group of European and American scholars in the field of anthropology established the European Association of Social Anthropologists (EASA) which serves as a major professional organization for anthropologists working in Europe. The EASA seeks to advance the status of anthropology in Europe and to increase visibility of marginalized anthropological traditions and thereby contribute to the project of a global anthropology or world anthropology. Hundreds of other organizations exist in the various sub-fields of anthropology, sometimes divided up by nation or region, and many anthropologists work with collaborators in other disciplines, such as geology, physics, zoology, paleontology, anatomy, music theory, art history, sociology and so on, belonging to professional societies in those disciplines as well. === List of major organizations === == Ethics == As the field has matured it has debated and arrived at ethical principles aimed at protecting both the subjects of anthropological research as well as the researchers themselves, and professional societies have generated codes of ethics.Anthropologists, like other researchers (especially historians and scientists engaged in field research), have over time assisted state policies and projects, especially colonialism.Some commentators have contended: That the discipline grew out of colonialism, perhaps was in league with it, and derives some of its key notions from it, consciously or not. (See, for example, Gough, Pels and Salemink, but cf. Lewis 2004). That ethnographic work is often ahistorical, writing about people as if they were "out of time" in an "ethnographic present" (Johannes Fabian, Time and Its Other). === Cultural relativism === As part of their quest for scientific objectivity, present-day anthropologists typically urge cultural relativism, which has an influence on all the sub-fields of anthropology. This is the notion that cultures should not be judged by another's values or viewpoints, but be examined dispassionately on their own terms. There should be no notions, in good anthropology, of one culture being better or worse than another culture.Ethical commitments in anthropology include noticing and documenting genocide, infanticide, racism, mutilation (including circumcision and subincision), and torture. Topics like racism, slavery, and human sacrifice attract anthropological attention and theories ranging from nutritional deficiencies to genes to acculturation have been proposed, not to mention theories of colonialism and many others as root causes of Man's inhumanity to man. To illustrate the depth of an anthropological approach, one can take just one of these topics, such as "racism" and find thousands of anthropological references, stretching across all the major and minor sub-fields. === Military involvement === Anthropologists' involvement with the U.S. government, in particular, has caused bitter controversy within the discipline. Franz Boas publicly objected to US participation in World War I, and after the war he published a brief expose and condemnation of the participation of several American archaeologists in espionage in Mexico under their cover as scientists. But by the 1940s, many of Boas' anthropologist contemporaries were active in the allied war effort against the "Axis" (Nazi Germany, Fascist Italy, and Imperial Japan). Many served in the armed forces, while others worked in intelligence (for example, Office of Strategic Services and the Office of War Information). At the same time, David H. Price's work on American anthropology during the Cold War provides detailed accounts of the pursuit and dismissal of several anthropologists from their jobs for communist sympathies. Attempts to accuse anthropologists of complicity with the CIA and government intelligence activities during the Vietnam War years have turned up surprisingly little. Many anthropologists (students and teachers) were active in the antiwar movement. Numerous resolutions condemning the war in all its aspects were passed overwhelmingly at the annual meetings of the American Anthropological Association (AAA). Professional anthropological bodies often object to the use of anthropology for the benefit of the state. Their codes of ethics or statements may proscribe anthropologists from giving secret briefings. The Association of Social Anthropologists of the UK and Commonwealth (ASA) has called certain scholarship ethically dangerous. The AAA's current 'Statement of Professional Responsibility' clearly states that "in relation with their own government and with host governments ... no secret research, no secret reports or debriefings of any kind should be agreed to or given." Anthropologists, along with other social scientists, are working with the US military as part of the US Army's strategy in Afghanistan. The Christian Science Monitor reports that "Counterinsurgency efforts focus on better grasping and meeting local needs" in Afghanistan, under the Human Terrain System (HTS) program; in addition, HTS teams are working with the US military in Iraq. In 2009, the American Anthropological Association's Commission on the Engagement of Anthropology with the US Security and Intelligence Communities released its final report concluding, in part, that, "When ethnographic investigation is determined by military missions, not subject to external review, where data collection occurs in the context of war, integrated into the goals of counterinsurgency, and in a potentially coercive environment – all characteristic factors of the HTS concept and its application – it can no longer be considered a legitimate professional exercise of anthropology. In summary, while we stress that constructive engagement between anthropology and the military is possible, CEAUSSIC suggests that the AAA emphasize the incompatibility of HTS with disciplinary ethics and practice for job seekers and that it further recognize the problem of allowing HTS to define the meaning of "anthropology" within DoD." == Post–World War II developments == Before WWII British 'social anthropology' and American 'cultural anthropology' were still distinct traditions. After the war, enough British and American anthropologists borrowed ideas and methodological approaches from one another that some began to speak of them collectively as 'sociocultural' anthropology. === Basic trends === There are several characteristics that tend to unite anthropological work. One of the central characteristics is that anthropology tends to provide a comparatively more holistic account of phenomena and tends to be highly empirical. The quest for holism leads most anthropologists to study a particular place, problem or phenomenon in detail, using a variety of methods, over a more extensive period than normal in many parts of academia. In the 1990s and 2000s (decade), calls for clarification of what constitutes a culture, of how an observer knows where his or her own culture ends and another begins, and other crucial topics in writing anthropology were heard. These dynamic relationships, between what can be observed on the ground, as opposed to what can be observed by compiling many local observations remain fundamental in any kind of anthropology, whether cultural, biological, linguistic or archaeological.Biological anthropologists are interested in both human variation and in the possibility of human universals (behaviors, ideas or concepts shared by virtually all human cultures). They use many different methods of study, but modern population genetics, participant observation and other techniques often take anthropologists "into the field," which means traveling to a community in its own setting, to do something called "fieldwork." On the biological or physical side, human measurements, genetic samples, nutritional data may be gathered and published as articles or monographs. Along with dividing up their project by theoretical emphasis, anthropologists typically divide the world up into relevant time periods and geographic regions. Human time on Earth is divided up into relevant cultural traditions based on material, such as the Paleolithic and the Neolithic, of particular use in archaeology. Further cultural subdivisions according to tool types, such as Olduwan or Mousterian or Levalloisian help archaeologists and other anthropologists in understanding major trends in the human past. Anthropologists and geographers share approaches to Culture regions as well, since mapping cultures is central to both sciences. By making comparisons across cultural traditions (time-based) and cultural regions (space-based), anthropologists have developed various kinds of comparative method, a central part of their science. === Commonalities between fields === Because anthropology developed from so many different enterprises (see History of Anthropology), including but not limited to fossil-hunting, exploring, documentary film-making, paleontology, primatology, antiquity dealings and curatorship, philology, etymology, genetics, regional analysis, ethnology, history, philosophy, and religious studies, it is difficult to characterize the entire field in a brief article, although attempts to write histories of the entire field have been made.Some authors argue that anthropology originated and developed as the study of "other cultures", both in terms of time (past societies) and space (non-European/non-Western societies). For example, the classic of urban anthropology, Ulf Hannerz in the introduction to his seminal Exploring the City: Inquiries Toward an Urban Anthropology mentions that the "Third World" had habitually received most of attention; anthropologists who traditionally specialized in "other cultures" looked for them far away and started to look "across the tracks" only in late 1960s.Now there exist many works focusing on peoples and topics very close to the author's "home". It is also argued that other fields of study, like History and Sociology, on the contrary focus disproportionately on the West.In France, the study of Western societies has been traditionally left to sociologists, but this is increasingly changing, starting in the 1970s from scholars like Isac Chiva and journals like Terrain ("fieldwork"), and developing with the center founded by Marc Augé (Le Centre d'anthropologie des mondes contemporains, the Anthropological Research Center of Contemporary Societies). Since the 1980s it has become common for social and cultural anthropologists to set ethnographic research in the North Atlantic region, frequently examining the connections between locations rather than limiting research to a single locale. There has also been a related shift toward broadening the focus beyond the daily life of ordinary people; increasingly, research is set in settings such as scientific laboratories, social movements, governmental and nongovernmental organizations and businesses. == See also == == Notes == == References == == Further reading == === Dictionaries and encyclopedias === === Fieldnotes and memoirs === === Histories === === Textbooks and key theoretical works === == External links == Haller, Dieter.

### Instruction: retrieve labels for this: Animation is a dynamic medium in which images or objects are manipulated to appear as moving images. In traditional animation, images are drawn or painted by hand on transparent celluloid sheets to be photographed and exhibited on film. Today most animations are made with computer-generated imagery (CGI). Computer animation can be very detailed 3D animation, while 2D computer animation can be used for stylistic reasons, low bandwidth or faster real-time renderings. Other common animation methods apply a stop motion technique to two and three-dimensional objects like paper cutouts, puppets or clay figures. The stop motion technique where live actors are used as a frame-by-frame subject is known as pixilation. Commonly the effect of animation is achieved by a rapid succession of sequential images that minimally differ from each other. The illusion—as in motion pictures in general—is thought to rely on the phi phenomenon and beta movement, but the exact causes are still uncertain. Analog mechanical animation media that rely on the rapid display of sequential images include the phénakisticope, zoetrope, flip book, praxinoscope and film. Television and video are popular electronic animation media that originally were analog and now operate digitally. For display on the computer, techniques like animated GIF and Flash animation were developed. Apart from short films, feature films, animated gifs and other media dedicated to the display moving images, animation is also heavily used for video games, motion graphics and special effects. The physical movement of image parts through simple mechanics in for instance the moving images in magic lantern shows can also be considered animation. Mechanical animation of actual robotic devices is known as animatronics. Animators are artists who specialize in creating animation. == Etymology == The word "animation" stems from the Latin "prd" (nominative "animatio"), noun of action from past participle stem of "animare", meaning "the action of imparting life". The primary meaning of the English word is "liveliness" and has been in use much longer than the meaning of "moving image medium". == History == The history of animation started long before the development of cinematography. Humans have probably attempted to depict motion as far back as the paleolithic period. Shadow play and the magic lantern offered popular shows with moving images as the result of manipulation by hand and/or some minor mechanics. A 5,200-year old pottery bowl discovered in Shahr-e Sukhteh, Iran, has five sequential images painted around it that seem to show phases of a goat leaping up to nip at a tree. In 1833 the phenakistiscope introduced the stroboscopic principle of modern animation, which would also provide the basis for the zoetrope (1866), the flip book (1868), the praxinoscope (1877) and cinematography. Charles-Émile Reynaud further developed his projection praxinoscope into the Théâtre Optique with transparent hand-painted colorful pictures in a long perforated strip wound between two spools, patented in December 1888. From 28 October 1892 to March 1900 Reynaud gave over 12,800 shows to a total of over 500.000 visitors at the Musée Grévin in Paris. His Pantomimes Lumineuses series of animated films each contained 300 to 700 frames that were manipulated back and forth to last 10 to 15 minutes per film. Piano music, song and some dialogue were performed live, while some sound effects were synchronized with an electromagnet. When film became a common medium some manufacturers of optical toys adapted small magic lanterns into toy film projectors for short loops of film. By 1902 they were producing many chromolithography film loops, usually by tracing live-action film footage (much like the later rotoscoping technique). Some early filmmakers, including J. Stuart Blackton, Arthur Melbourne-Cooper, Segundo de Chomón and Edwin S. Porter experimented with stop-motion animation, possibly since around 1899. Blackton's The Haunted Hotel (1907) was the first huge success that baffled audiences with objects apparently moving by themselves and inspired other filmmakers to try the technique for themselves. J. Stuart Blackton also experimented with animation drawn on blackboards and some cutout animation in Humorous Phases of Funny Faces (1906). In 1908 Émile Cohl's Fantasmagorie was released with a white-on-black chalkline look created with negative prints from black ink drawings on white paper. The film largely consists of a stick figure moving about and encountering all kinds of morphing objects, including a wine bottle that transforms into a flower.Inspired by Émile Cohl's stop-motion film Les allumettes animées [Animated Matches] (1908), Ladislas Starevich started making his influential puppet animations in 1910. Winsor McCay's Little Nemo (1911) showcased very detailed drawings. His Gertie the Dinosaur (1914) was an also an early example of character development in drawn animation. During the 1910s, the production of animated short films typically referred to as "cartoons", became an industry of its own and cartoon shorts were produced for showing in movie theaters. The most successful producer at the time was John Randolph Bray, who, along with animator Earl Hurd, patented the cel animation process that dominated the animation industry for the rest of the decade. El Apóstol (Spanish: "The Apostle") was a 1917 Argentine animated film utilizing cutout animation, and the world's first animated feature film. Unfortunately, a fire that destroyed producer Federico Valle's film studio incinerated the only known copy of El Apóstol, and it is now considered a lost film.The earliest extant feature length animated film is The Adventures of Prince Achmed (1926) made by director Lotte Reiniger and her collaborators Carl Koch and Berthold Bartosch. In 1932, the first short animated film created entirely with Technicolor (using red/green/blue photographic filters and three strips of film) was Walt Disney's Flowers and Trees, directed by Burt Gillett. But, the first feature film that was done with this technique, apart from the movie The Vanities Fair (1935), by Rouben Mamoulian, was "Snow White and the Seven Dwarfs", also by Walt Disney.In 1958, Hanna-Barbera released The Huckleberry Hound Show, the first half hour television program to feature only in animation. Terrytoons released Tom Terrific that same year. Television significantly decreased public attention to the animated shorts being shown in theaters.Computer animation has become popular since Toy Story (1995), the first feature-length animated film completely made using this technique.In 2008, the animation market was worth US$68.4 billion. Animation as an art and industry continues to thrive as of the mid-2010s because well-made animated projects can find audiences across borders and in all four quadrants. Animated feature-length films returned the highest gross margins (around 52%) of all film genres in the 2004–2013 timeframe. == Techniques == === Traditional animation === Traditional animation (also called cel animation or hand-drawn animation) was the process used for most animated films of the 20th century. The individual frames of a traditionally animated film are photographs of drawings, first drawn on paper. To create the illusion of movement, each drawing differs slightly from the one before it. The animators' drawings are traced or photocopied onto transparent acetate sheets called cels, which are filled in with paints in assigned colors or tones on the side opposite the line drawings. The completed character cels are photographed one-by-one against a painted background by a rostrum camera onto motion picture film.The traditional cel animation process became obsolete by the beginning of the 21st century. Today, animators' drawings and the backgrounds are either scanned into or drawn directly into a computer system. Various software programs are used to color the drawings and simulate camera movement and effects. The final animated piece is output to one of several delivery media, including traditional 35 mm film and newer media with digital video. The "look" of traditional cel animation is still preserved, and the character animators' work has remained essentially the same over the past 70 years. Some animation producers have used the term "tradigital" (a play on the words "traditional" and "digital") to describe cel animation that uses significant computer technology. Examples of traditionally animated feature films include Pinocchio (United States, 1940), Animal Farm (United Kingdom, 1954), Lucky and Zorba (Italy, 1998), and The Illusionist (British-French, 2010). Traditionally animated films produced with the aid of computer technology include The Lion King (US, 1994), The Prince of Egypt (US, 1998), Akira (Japan, 1988), Spirited Away (Japan, 2001), The Triplets of Belleville (France, 2003), and The Secret of Kells (Irish-French-Belgian, 2009). ==== Full animation ==== Full animation refers to the process of producing high-quality traditionally animated films that regularly use detailed drawings and plausible movement, having a smooth animation. Fully animated films can be made in a variety of styles, from more realistically animated works like those produced by the Walt Disney studio (The Little Mermaid, Beauty and the Beast, Aladdin, The Lion King) to the more 'cartoon' styles of the Warner Bros. animation studio. Many of the Disney animated features are examples of full animation, as are non-Disney works, The Secret of NIMH (US, 1982), The Iron Giant (US, 1999), and Nocturna (Spain, 2007). Fully animated films are animated at 24 frames per second, with a combination of animation on ones and twos, meaning that drawings can be held for one frame out of 24 or two frames out of 24. ==== Limited animation ==== Limited animation involves the use of less detailed or more stylized drawings and methods of movement usually a choppy or "skippy" movement animation. Limited animation uses fewer drawings per second, thereby limiting the fluidity of the animation. This is a more economic technique. Pioneered by the artists at the American studio United Productions of America, limited animation can be used as a method of stylized artistic expression, as in Gerald McBoing-Boing (US, 1951), Yellow Submarine (UK, 1968), and certain anime produced in Japan. Its primary use, however, has been in producing cost-effective animated content for media for television (the work of Hanna-Barbera, Filmation, and other TV animation studios) and later the Internet (web cartoons). ==== Rotoscoping ==== Rotoscoping is a technique patented by Max Fleischer in 1917 where animators trace live-action movement, frame by frame. The source film can be directly copied from actors' outlines into animated drawings, as in The Lord of the Rings (US, 1978), or used in a stylized and expressive manner, as in Waking Life (US, 2001) and A Scanner Darkly (US, 2006). Some other examples are Fire and Ice (US, 1983), Heavy Metal (1981), and Aku no Hana (2013). ==== Live-action/animation ==== Live-action/animation is a technique combining hand-drawn characters into live action shots or live action actors into animated shots. One of the earlier uses was in Koko the Clown when Koko was drawn over live action footage. Other examples include Allegro Non Troppo (Italy, 1976), Who Framed Roger Rabbit (US, 1988), Space Jam (US, 1996) and Osmosis Jones (US, 2001). === Stop motion animation === Stop-motion animation is used to describe animation created by physically manipulating real-world objects and photographing them one frame of film at a time to create the illusion of movement. There are many different types of stop-motion animation, usually named after the medium used to create the animation. Computer software is widely available to create this type of animation; traditional stop motion animation is usually less expensive but more time-consuming to produce than current computer animation. Puppet animation typically involves stop-motion puppet figures interacting in a constructed environment, in contrast to real-world interaction in model animation. The puppets generally have an armature inside of them to keep them still and steady to constrain their motion to particular joints. Examples include The Tale of the Fox (France, 1937), The Nightmare Before Christmas (US, 1993), Corpse Bride (US, 2005), Coraline (US, 2009), the films of Jiří Trnka and the adult animated sketch-comedy television series Robot Chicken (US, 2005–present). Puppetoon, created using techniques developed by George Pal, are puppet-animated films that typically use a different version of a puppet for different frames, rather than simply manipulating one existing puppet. Clay animation, or Plasticine animation (often called claymation, which, however, is a trademarked name), uses figures made of clay or a similar malleable material to create stop-motion animation. The figures may have an armature or wire frame inside, similar to the related puppet animation (below), that can be manipulated to pose the figures. Alternatively, the figures may be made entirely of clay, in the films of Bruce Bickford, where clay creatures morph into a variety of different shapes. Examples of clay-animated works include The Gumby Show (US, 1957–1967), Mio Mao (Italy, 1974-2005), Morph shorts (UK, 1977–2000), Wallace and Gromit shorts (UK, as of 1989), Jan Švankmajer's Dimensions of Dialogue (Czechoslovakia, 1982), The Trap Door (UK, 1984). Films include Wallace & Gromit: The Curse of the Were-Rabbit, Chicken Run and The Adventures of Mark Twain.Strata-cut animation, Strata-cut animation is most commonly a form of clay animation in which a long bread-like "loaf" of clay, internally packed tight and loaded with varying imagery, is sliced into thin sheets, with the animation camera taking a frame of the end of the loaf for each cut, eventually revealing the movement of the internal images within. Cutout animation is a type of stop-motion animation produced by moving two-dimensional pieces of material paper or cloth. Examples include Terry Gilliam's animated sequences from Monty Python's Flying Circus (UK, 1969–1974); Fantastic Planet (France/Czechoslovakia, 1973) ; Tale of Tales (Russia, 1979), The pilot episode of the adult television sitcom series (and sometimes in episodes) of South Park (US, 1997) and the music video Live for the moment, from Verona Riots band (produced by Alberto Serrano and Nívola Uyá, Spain 2014). Silhouette animation is a variant of cutout animation in which the characters are backlit and only visible as silhouettes. Examples include The Adventures of Prince Achmed (Weimar Republic, 1926) and Princes et princesses (France, 2000). Model animation refers to stop-motion animation created to interact with and exist as a part of a live-action world. Intercutting, matte effects and split screens are often employed to blend stop-motion characters or objects with live actors and settings. Examples include the work of Ray Harryhausen, as seen in films, Jason and the Argonauts (1963), and the work of Willis H. O'Brien on films, King Kong (1933). Go motion is a variant of model animation that uses various techniques to create motion blur between frames of film, which is not present in traditional stop-motion. The technique was invented by Industrial Light & Magic and Phil Tippett to create special effect scenes for the film The Empire Strikes Back (1980). Another example is the dragon named "Vermithrax" from Dragonslayer (1981 film). Object animation refers to the use of regular inanimate objects in stop-motion animation, as opposed to specially created items.Graphic animation uses non-drawn flat visual graphic material (photographs, newspaper clippings, magazines, etc.), which are sometimes manipulated frame-by-frame to create movement. At other times, the graphics remain stationary, while the stop-motion camera is moved to create on-screen action. Brickfilm are a subgenre of object animation involving using Lego or other similar brick toys to make an animation. These have had a recent boost in popularity with the advent of video sharing sites, YouTube and the availability of cheap cameras and animation software. Pixilation involves the use of live humans as stop motion characters. This allows for a number of surreal effects, including disappearances and reappearances, allowing people to appear to slide across the ground, and other effects. Examples of pixilation include The Secret Adventures of Tom Thumb and Angry Kid shorts, and the academy award-winning Neighbours by Norman McLaren. === Computer animation === Computer animation encompasses a variety of techniques, the unifying factor being that the animation is created digitally on a computer. 2D animation techniques tend to focus on image manipulation while 3D techniques usually build virtual worlds in which characters and objects move and interact. 3D animation can create images that seem real to the viewer. ==== 2D animation ==== 2D animation figures are created or edited on the computer using 2D bitmap graphics and 2D vector graphics. This includes automated computerized versions of traditional animation techniques, interpolated morphing, onion skinning and interpolated rotoscoping. 2D animation has many applications, including analog computer animation, Flash animation, and PowerPoint animation. Cinemagraphs are still photographs in the form of an animated GIF file of which part is animated.Final line advection animation is a technique used in 2D animation, to give artists and animators more influence and control over the final product as everything is done within the same department. Speaking about using this approach in Paperman, John Kahrs said that "Our animators can change things, actually erase away the CG underlayer if they want, and change the profile of the arm." ==== 3D animation ==== 3D animation is digitally modeled and manipulated by an animator. The animator usually starts by creating a 3D polygon mesh to manipulate. A mesh typically includes many vertices that are connected by edges and faces, which give the visual appearance of form to a 3D object or 3D environment. Sometimes, the mesh is given an internal digital skeletal structure called an armature that can be used to control the mesh by weighting the vertices. This process is called rigging and can be used in conjunction with keyframes to create movement.Other techniques can be applied, mathematical functions (e.g., gravity, particle simulations), simulated fur or hair, and effects, fire and water simulations. These techniques fall under the category of 3D dynamics. ===== 3D terms ===== Cel-shaded animation is used to mimic traditional animation using computer software. Shading looks stark, with less blending of colors. Examples include Skyland (2007, France), The Iron Giant (1999, United States), Futurama (Fox, 1999) Appleseed Ex Machina (2007, Japan), The Legend of Zelda: The Wind Waker (2002, Japan), The Legend of Zelda: Breath of the Wild (2017, Japan) Machinima – Films created by screen capturing in video games and virtual worlds. The term originated from the software introduction in the 1980s demoscene, as well as the 1990s recordings of the first-person shooter video game Quake. Motion capture is used when live-action actors wear special suits that allow computers to copy their movements into CG characters. Examples include Polar Express (2004, US), Beowulf (2007, US), A Christmas Carol (2009, US), The Adventures of Tintin (2011, US) kochadiiyan (2014, India). Photo-realistic animation is used primarily for animation that attempts to resemble real life, using advanced rendering that mimics in detail skin, plants, water, fire, clouds, etc. Examples include Up (2009, US), How to Train Your Dragon (2010, US) === Mechanical animation === Animatronics is the use of mechatronics to create machines that seem animate rather than robotic. Audio-Animatronics and Autonomatronics is a form of robotics animation, combined with 3-D animation, created by Walt Disney Imagineering for shows and attractions at Disney theme parks move and make noise (generally a recorded speech or song). They are fixed to whatever supports them. They can sit and stand, and they cannot walk. An Audio-Animatron is different from an android-type robot in that it uses prerecorded movements and sounds, rather than responding to external stimuli. In 2009, Disney created an interactive version of the technology called Autonomatronics. Linear Animation Generator is a form of animation by using static picture frames installed in a tunnel or a shaft. The animation illusion is created by putting the viewer in a linear motion, parallel to the installed picture frames. The concept and the technical solution were invented in 2007 by Mihai Girlovan in Romania. Chuckimation is a type of animation created by the makers of the television series Action League Now! in which characters/props are thrown, or chucked from off camera or wiggled around to simulate talking by unseen hands. Puppetry is a form of theatre or performance animation that involves the manipulation of puppets. It is very ancient and is believed to have originated 3000 years BC. Puppetry takes many forms, they all share the process of animating inanimate performing objects. Puppetry is used in almost all human societies both as entertainment – in performance – and ceremonially in rituals, celebrations, and carnivals. Most puppetry involves storytelling. The magic lantern used mechanical slides to project moving images, probably since Christiaan Huygens invented this early image projector in 1659. === Other animation styles, techniques, and approaches === Hydrotechnics: a technique that includes lights, water, fire, fog, and lasers, with high-definition projections on mist screens. Drawn on film animation: a technique where footage is produced by creating the images directly on film stock, for example by Norman McLaren, Len Lye and Stan Brakhage. Paint-on-glass animation: a technique for making animated films by manipulating slow drying oil paints on sheets of glass, for example by Aleksandr Petrov. Erasure animation: a technique using traditional 2D media, photographed over time as the artist manipulates the image. For example, William Kentridge is famous for his charcoal erasure films, and Piotr Dumała for his auteur technique of animating scratches on plaster. Pinscreen animation: makes use of a screen filled with movable pins that can be moved in or out by pressing an object onto the screen. The screen is lit from the side so that the pins cast shadows. The technique has been used to create animated films with a range of textural effects difficult to achieve with traditional cel animation. Sand animation: sand is moved around on a back- or front-lighted piece of glass to create each frame for an animated film. This creates an interesting effect when animated because of the light contrast. Flip book: a flip book (sometimes, especially in British English, called a flick book) is a book with a series of pictures that vary gradually from one page to the next, so that when the pages are turned rapidly, the pictures appear to animate by simulating motion or some other change. Flip books are often illustrated books for children, they also be geared towards adults and employ a series of photographs rather than drawings. Flip books are not always separate books, they appear as an added feature in ordinary books or magazines, often in the page corners. Software packages and websites are also available that convert digital video files into custom-made flip books. Character animation Multi-sketching Special effects animation == Animator == An animator is an artist who creates a visual sequence (or audio-visual if added sound) of multiple sequential images that generate the illusion of movement, that is, an animation. Animations are currently in many areas of technology and video, such as cinema, television, video games or the internet. Generally, these works require the collaboration of several animators. The methods to create these images depend on the animator and style that one wants to achieve (with images generated by computer, manually ...). Animators can be divided into animators of characters (artists who are specialized in the movements, dialogue and acting of the characters) and animators of special effects (for example vehicles, machinery or natural phenomena such as water, snow, rain). == Production == The creation of non-trivial animation works (i.e., longer than a few seconds) has developed as a form of filmmaking, with certain unique aspects. Traits common to both live-action and animated feature-length films are labor-intensity and high production costs.The most important difference is that once a film is in the production phase, the marginal cost of one more shot is higher for animated films than live-action films. It is relatively easy for a director to ask for one more take during principal photography of a live-action film, but every take on an animated film must be manually rendered by animators (although the task of rendering slightly different takes has been made less tedious by modern computer animation). It is pointless for a studio to pay the salaries of dozens of animators to spend weeks creating a visually dazzling five-minute scene if that scene fails to effectively advance the plot of the film. Thus, animation studios starting with Disney began the practice in the 1930s of maintaining story departments where storyboard artists develop every single scene through storyboards, then handing the film over to the animators only after the production team is satisfied that all the scenes make sense as a whole. While live-action films are now also storyboarded, they enjoy more latitude to depart from storyboards (i.e., real-time improvisation).Another problem unique to animation is the requirement to maintain a film's consistency from start to finish, even as films have grown longer and teams have grown larger. Animators, like all artists, necessarily have individual styles, but must subordinate their individuality in a consistent way to whatever style is employed on a particular film. Since the early 1980s, teams of about 500 to 600 people, of whom 50 to 70 are animators, typically have created feature-length animated films. It is relatively easy for two or three artists to match their styles; synchronizing those of dozens of artists is more difficult.This problem is usually solved by having a separate group of visual development artists develop an overall look and palette for each film before animation begins. Character designers on the visual development team draw model sheets to show how each character should look like with different facial expressions, posed in different positions, and viewed from different angles. On traditionally animated projects, maquettes were often sculpted to further help the animators see how characters would look from different angles.Unlike live-action films, animated films were traditionally developed beyond the synopsis stage through the storyboard format; the storyboard artists would then receive credit for writing the film. In the early 1960s, animation studios began hiring professional screenwriters to write screenplays (while also continuing to use story departments) and screenplays had become commonplace for animated films by the late 1980s. == Criticism == Criticism of animation has been common in media and cinema since its inception. With its popularity, a large amount of criticism has arisen, especially animated feature-length films. Many concerns of cultural representation, psychological effects on children have been brought up around the animation industry, which has remained rather politically unchanged and stagnant since its inception into mainstream culture. == Animation and Human Rights == Currently, animation is used as a method of entertainment, and employed to criticize or defend certain aspects of society. Most of these projects have been nominated for the Oscars or have gone viral on the Internet. For example, In a Heartbeat, directed by the American Esteban Bravo and Beth David, is one of the candidates to take the Best Animated Short Film award at the Oscars 2018. "In a Heartbeat" is about a love story between two teenage boys, as the directors wanted to break the prejudices towards the LGBT community. It's a short animation without dialogue where the heart of one of the boys escapes to pursue the other young person. The short film already has more than 32 million views on YouTube, and despite its success, it has created some controversy. == Awards == As with any other form of media, animation too has instituted awards for excellence in the field. The original awards for animation were presented by the Academy of Motion Picture Arts and Sciences for animated shorts from the year 1932, during the 5th Academy Awards function. The first winner of the Academy Award was the short Flowers and Trees, a production by Walt Disney Productions. The Academy Award for a feature-length animated motion picture was only instituted for the year 2001, and awarded during the 74th Academy Awards in 2002. It was won by the film Shrek, produced by DreamWorks and Pacific Data Images. Disney/Pixar have produced the most films either to win or be nominated for the award. The list of both awards can be obtained here: Academy Award for Best Animated Feature Academy Award for Best Animated Short FilmSeveral other countries have instituted an award for best animated feature film as part of their national film awards: Africa Movie Academy Award for Best Animation (since 2008), BAFTA Award for Best Animated Film (since 2006), César Award for Best Animated Film (since 2011), Golden Rooster Award for Best Animation (since 1981), Goya Award for Best Animated Film (since 1989), Japan Academy Prize for Animation of the Year (since 2007), National Film Award for Best Animated Film (since 2006). Also since 2007, the Asia Pacific Screen Award for Best Animated Feature Film has been awarded at the Asia Pacific Screen Awards. Since 2009, the European Film Awards have awarded the European Film Award for Best Animated Film. The Annie Award is another award presented for excellence in the field of animation. Unlike the Academy Awards, the Annie Awards are only received for achievements in the field of animation and not for any other field of technical and artistic endeavor. They were re-organized in 1992 to create a new field for Best Animated feature. The 1990s winners were dominated by Walt Disney, however, newer studios, led by Pixar & DreamWorks, have now begun to consistently vie for this award.

### Instruction: retrieve labels for this: Andre Kirk Agassi ( AG-ə-see; born April 29, 1970) is an American retired professional tennis player and former world No. 1 who was one of the sport's most dominant players from the early 1990s to the mid-2000s. Generally considered by critics and fellow players to be one of the greatest tennis players of all time, Agassi has been called the greatest service returner ever to play the game and was described by the BBC upon his retirement as "perhaps the biggest worldwide star in the sport's history". As a result, he is credited for helping to revive the popularity of tennis during the 1990s.In singles tennis, Agassi is an eight-time Grand Slam champion and a 1996 Olympic gold medalist, as well as being a runner-up in seven other Grand Slam tournaments. During the Open Era, Agassi was the first male player to win four Australian Open titles, a record that was later surpassed by Novak Djokovic when he won his fifth title in 2015, and then by Roger Federer in 2017. Agassi is one of five male singles players to achieve the Career Grand Slam in the Open Era and one of eight in history, the first of two to achieve the Career Golden Slam (Career Grand Slam and Olympic Gold Medal, the other being Rafael Nadal), and the only man to win the Career Golden Slam and the ATP Tour World Championships: a distinction dubbed as a "Career Super Slam" by Sports Illustrated.Agassi was the first male player to win all four Grand Slam tournaments on three different surfaces (hard, clay and grass), and the last American male to win both the French Open (in 1999) and the Australian Open (in 2003). He also won 17 ATP Masters Series titles and was part of the winning Davis Cup teams in 1990, 1992 and 1995. Agassi reached the world No. 1 ranking for the first time in 1995 but was troubled by personal issues during the mid-to-late 1990s and sank to No. 141 in 1997, prompting many to believe that his career was over. Agassi returned to No. 1 in 1999 and enjoyed the most successful run of his career over the next four years. During his 20-plus year tour career, Agassi was known by the nickname "The Punisher".After suffering from sciatica caused by two bulging discs in his back, a spondylolisthesis (vertebral displacement) and a bone spur that interfered with the nerve, Agassi retired from professional tennis on September 3, 2006, after losing in the third round of the US Open to Benjamin Becker. He is the founder of the Andre Agassi Charitable Foundation, which has raised over $60 million for at-risk children in Southern Nevada. In 2001, the Foundation opened the Andre Agassi College Preparatory Academy in Las Vegas, a K-12 public charter school for at-risk children. He has been married to fellow tennis player Steffi Graf since 2001. == 1970–1985: Early life == Andre Agassi was born in Las Vegas, Nevada to Emmanuel "Mike" Agassi, a former Olympic boxer from Iran and Elizabeth "Betty" Agassi (née Dudley). His father claims to have Armenian and Assyrian heritage. One of his ancestors changed his surname from Aghassian to Agassi to avoid persecution. Andre Agassi's mother, Betty, is a breast cancer survivor. He has three older siblings – Rita (last wife to Pancho Gonzales), Philip and Tami. Andre was given the middle name Kirk after Kirk Kerkorian, an Armenian American billionaire. Agassi, a waiter at Tropicana Las Vegas, met Kekorian in 1963.Agassi at the age of 12 (with his good friend and doubles partner Roddy Parks) won the 1982 National Indoor Boys 14’s Double’s Championship in Chicago, IL. Agassi describes more of his memorable experiences and juvenile pranks with Roddy in his book Open.At the age of 13, Agassi was sent to Nick Bollettieri's Tennis Academy in Florida. He was meant to stay for only 3 months because that was all his father could afford. After thirty minutes of watching Agassi play, Bollettieri called Mike and said: "Take your check back. He's here for free," claiming that Agassi had more natural talent than anyone else he had seen. Agassi dropped out of school in the ninth grade. == International tennis career biography == === 1986–1993: Breakthrough and the first major title === Agassi turned professional at the age of 16 and competed in his first tournament at La Quinta, California. He won his first match against John Austin, but then lost his second match to Mats Wilander. By the end of 1986, Agassi was ranked No. 91. He won his first top-level singles title in 1987 at the Sul American Open in Itaparica and ended the year ranked No. 25. He won six additional tournaments in 1988 (Memphis, U.S. Men's Clay Court Championships, Forest Hills WCT, Stuttgart Outdoor, Volvo International and Livingston Open), and, by December of that year, he had surpassed US$1 million in career prize money after playing in just 43 tournaments—the fastest anyone in history had reached that level. During 1988, he also set the open-era record for most consecutive victories by a male teenager (a record that stood for 17 years until Rafael Nadal broke it in 2005). His year-end ranking was No. 3, behind second-ranked Ivan Lendl and top-ranked Mats Wilander. Both the Association of Tennis Professionals and Tennis magazine named Agassi the Most Improved Player of the Year for 1988.In addition to not playing the Australian Open (which later became his best Grand Slam event) for the first eight years of his career, Agassi chose not to play at Wimbledon from 1988 through 1990 and publicly stated that he did not wish to play there because of the event's traditionalism, particularly its "predominantly white" dress code to which players at the event are required to conform. Strong performances on the tour meant that Agassi was quickly tipped as a future Grand Slam champion. While still a teenager, he reached the semifinals of both the French Open and the US Open in 1988 and made the US Open semifinals in 1989. He began the 1990s with a series of near-misses. He reached his first Grand Slam final in 1990 at the French Open, where he was favored before losing in four sets to Andrés Gómez, which he later attributed in his book to worrying about his wig falling off during the match. He reached his second Grand Slam final of the year at the US Open, defeating defending champion Boris Becker in the semifinals. His opponent in the final was Pete Sampras; a year earlier, Agassi had crushed Sampras, after which time he told his coach that he felt bad for Sampras because he was never going to make it as a pro. Agassi lost the US Open final to Sampras in three sets. The rivalry between these two American players became the dominant rivalry in tennis over the rest of the decade. Agassi ended 1990 on high note as he helped the United States win its first Davis Cup in 8 years and won his only Tennis Masters Cup, beating reigning Wimbledon champion Stefan Edberg in the final. In 1991, Agassi reached his second consecutive French Open final, where he faced fellow Bollettieri Academy alumnus Jim Courier. Courier emerged the victor in a five-set final. Agassi decided to play at Wimbledon in 1991, leading to weeks of speculation in the media about the clothes he would wear. He eventually emerged for the first round in a completely white outfit. He reached the quarterfinals on that occasion, losing in five sets to David Wheaton. Agassi's Grand Slam tournament breakthrough came at Wimbledon, not at the French Open or the US Open, where he had previously enjoyed success. In 1992, he defeated Goran Ivanišević in a five-set final. Along the way, Agassi overcame two former Wimbledon champions: Boris Becker and John McEnroe. No other baseliner would triumph at Wimbledon until Lleyton Hewitt ten years later. Agassi was named the BBC Overseas Sports Personality of the Year in 1992. Agassi once again played on the United States' Davis Cup winning team in 1992. It was their second Davis cup title in three years. In 1993, Agassi won the only doubles title of his career, at the Cincinnati Masters, partnered with Petr Korda. He missed much of the early part of that year due to injuries. Although he made the quarterfinals in his Wimbledon title defense, he lost to eventual champion and No. 1 Pete Sampras in five sets. Agassi lost in the first round at the US Open to Thomas Enqvist and required wrist surgery late in the year. === 1994–1997: Rise to the top, Olympic Gold and the fall === With new coach Brad Gilbert on board, Agassi began to employ more of a tactical, consistent approach, which fueled his resurgence. He started slowly in 1994, losing in the first week at the French Open and Wimbledon. Nevertheless, he emerged during the hard-court season, winning the Canadian Open. His comeback culminated at the 1994 US Open with a five-set fourth-round victory against compatriot Michael Chang. He then became the first man to capture the US Open as an unseeded player, beating Michael Stich in the final. Along the way, he beat 5 seeded players. In 1995, Agassi shaved his balding head, breaking with his old "image is everything" style. He competed in the 1995 Australian Open (his first appearance at the event) and won, beating Sampras in a four-set final. Agassi and Sampras met in five tournament finals in 1995, all on hardcourt, with Agassi winning three. Agassi won three Masters Series events in 1995 (Cincinnati, Key Biscayne, and the Canadian Open) and seven titles total. He compiled a career-best 26-match winning streak during the summer hard-court circuit, with the last victory being in an intense late night four-set semifinal of the US Open against Boris Becker. The streak ended the next day when Agassi lost the final to Sampras. Agassi reached the world No. 1 ranking for the first time in April 1995. He held that ranking until November, for a total of 30 weeks. Agassi skipped most of the fall indoor season which allowed Sampras to surpass him and finish ranked No. 1 at the year-end ranking. In terms of win/loss record, 1995 was Agassi's best year. He won 73 and lost 9 matches, and was also once again a key player on the United States' Davis Cup winning team—the third and final Davis Cup title of his career. 1996 was a less successful year for Agassi, as he failed to reach any Grand Slam final. He suffered two early-round losses at the hands of compatriots Chris Woodruff and Doug Flach at the French Open and Wimbledon, respectively, and lost to Chang in straight sets in the Australian and US Open semifinals. At the time, Agassi blamed the Australian Open loss on the windy conditions, but later said in his biography that he had lost the match on purpose, as he did not want to play Boris Becker, whom he would have faced in that final. The high point for Agassi was winning the men's singles gold medal at the Olympic Games in Atlanta, beating Sergi Bruguera of Spain in the final. Agassi also successfully defended his singles titles in Cincinnati and Key Biscayne. 1997 was the low point of Agassi's career. His wrist injury resurfaced, and he played only 24 matches during the year. He later confessed that he started using crystal methamphetamine at that time, allegedly on the urging of a friend. He failed an ATP drug test, but wrote a letter claiming the same friend had spiked a drink. The ATP dropped the failed drug test as a warning. In his autobiography, Agassi admitted that the letter was a lie. He quit the drug soon after. At this time Agassi was also in a failing marriage with actress Brooke Shields and had lost interest in the game. He won no top-level titles, and his ranking sank to No. 141 on November 10, 1997, prompting many to believe that his run as one of the sport's premier competitors was over and he would never again win any significant championships. === 1998–2003: Return to glory and Career Super Slam === In 1998, Agassi began a rigorous conditioning program and worked his way back up the rankings by playing in Challenger Series tournaments, a circuit for pro players ranked outside the world's top 50. After returning to top physical and mental shape, Agassi recorded the most successful period of his tennis career and also played classic matches in that period against Pete Sampras and Patrick Rafter. In 1998, Agassi won five titles and leapt from No. 110 to No. 6, the highest jump into the top 10 made by any player during a calendar year. At Wimbledon, he had an early loss in the second round to Tommy Haas. He won five titles in ten finals and was runner-up at the Masters Series tournament in Key Biscayne, losing to Marcelo Ríos, who became No. 1 as a result. At the year end he was awarded the ATP Most Improved Player of the Year for the second time in his career (the first being 10 years earlier in 1988). Agassi entered the history books in 1999 when he came back from two sets to love down to beat Andrei Medvedev in a five-set French Open final, becoming, at the time, only the fifth male player (joining Rod Laver, Fred Perry, Roy Emerson and Don Budge—these have since been joined by Roger Federer, Rafael Nadal, and Novak Djokovic) to win all four Grand Slam singles titles during his career. Only Laver, Agassi, Federer, Nadal and Djokovic have achieved this feat during the open era. This win also made him the first (of only four, the next being Federer, Nadal and Djokovic respectively) male player in history to have won all four Grand Slam titles on three different surfaces (clay, grass and hard courts). Agassi also became the only male player to win the Career Super Slam, consisting of all four Grand Slam tournaments plus an Olympic gold medal in singles and a Year-End Championship.Agassi followed his 1999 French Open victory by reaching the Wimbledon final, where he lost to Sampras in straight sets. He rebounded from his Wimbledon defeat by winning the US Open, beating Todd Martin in five sets (rallying from a two sets to one deficit) in the final. Overall during the year Agassi won 5 titles including two majors and the ATP Masters Series in Paris, where he beat Marat Safin. Agassi ended 1999 as the No. 1, ending Sampras's record of six consecutive year-ending top rankings (1993–98). This was the only time Agassi ended the year at No. 1. He began the next year by capturing his second Australian Open title, beating Sampras in a five-set semifinal and Yevgeny Kafelnikov in a four-set final. He was the first male player to have reached four consecutive Grand Slam finals since Rod Laver achieved the Grand Slam in 1969. At the time, Agassi was also only the fourth player since Laver to be the reigning champion of three of four Grand Slam events, missing only the Wimbledon title.. 2000 also saw Agassi reach the semifinals at Wimbledon, where he lost in five sets to Rafter in a match considered by many to be one of the best ever at Wimbledon. At the inaugural Tennis Masters Cup in Lisbon, Agassi reached the final after defeating Marat Safin in the semifinals to end the Russian's hopes to become the youngest No. 1 in the history of tennis. Agassi then lost to Gustavo Kuerten in the final, allowing Kuerten to be crowned year-end No. 1. Agassi opened 2001 by successfully defending his Australian Open title with a straight-sets final win over Arnaud Clément. En route, he beat a cramping Rafter in five sets in front of a sell-out crowd in what turned out to be the Aussie's last Australian Open. At Wimbledon, they met again in the semifinals, where Agassi lost another close match to Rafter, 8–6 in the fifth set. In the quarterfinals at the US Open, Agassi lost a 3-hour, 33 minute epic match with Sampras, 7–6, 6–7, 6–7, 6–7, with no breaks of serve during the 52-game match. Despite the setback, Agassi finished 2001 ranked No. 3, becoming the only male tennis player to finish a year ranked in the top 3 in three different decades (1980s, 1990s, 2000s). He also was the oldest player (age 31) to finish in the top three since 32-year-old Connors finished at No. 2 in 1984.2002 opened with disappointment for Agassi, as injury forced him to skip the Australian Open, where he was a two-time defending champion. Agassi recovered from the injury and later that year defended his Key Biscayne title beating then rising Roger Federer in a four-set final. The last duel between Agassi and Sampras came in the final of the US Open, which Sampras won in four sets and left Sampras with a 20–14 edge in their 34 career meetings. The match was the last of Sampras's career. Agassi's US Open finish, along with his Masters Series victories in Key Biscayne, Rome and Madrid, helped him finish 2002 as the oldest year-end No. 2 at 32 years and 8 months.In 2003, Agassi won the eighth (and final) Grand Slam title of his career at the Australian Open, where he beat Rainer Schüttler in straight sets in the final. In March, he won his sixth career and third consecutive Key Biscayne title, in the process surpassing his wife, Steffi Graf, who was a five-time winner of the event. The final was his 18th straight win in that tournament, which broke the previous record of 17 set by Sampras from 1993–95. (Agassi's winning streak continued to 20 after winning his first two matches at the 2004 edition of that tournament before bowing to Agustín Calleri.) With the victory, Agassi became the youngest (19 years old) and oldest (32) winner of the Key Biscayne tournament. On April 28, 2003, he recaptured the No. 1 ranking after a quarterfinal victory over Xavier Malisse at the Queen's Club Championships to become the oldest top-ranked male player since the ATP rankings began at 33 years and 13 days. The record was later surpassed by Roger Federer in 2018. He had held the No. 1 ranking for two weeks, when Lleyton Hewitt took it back on May 12, 2003. Agassi then recaptured the No. 1 ranking once again on June 16, 2003, which he held for 12 weeks until September 7, 2003. During his career, Agassi held the No. 1 ranking for a total of 101 weeks. Agassi's ranking slipped when injuries forced him to withdraw from many events. He did manage to reach the US Open semifinals, where he lost to Juan Carlos Ferrero and surrendered his No. 1 ranking to Ferrero. At the year-end Tennis Masters Cup, Agassi lost in the final to Federer and finished the year ranked No. 4. At age 33, he was the oldest player to rank in the top 5 since Connors, at age 35, was No. 4 in 1987. === 2004–2006: Final years === In 2004, Agassi began the year with a five-set loss in the semifinals of the Australian Open to Marat Safin; the loss ended Agassi's 26-match winning streak at the event, a record that still stands. He won the Masters series event in Cincinnati to bring his career total to 59 top-level singles titles and a record 17 ATP Masters Series titles, having already won seven of the nine ATP Masters tournament—all except the tournaments in Monte Carlo and Hamburg. At 34, he became the second-oldest singles champion in Cincinnati tournament history (the tournament began in 1899), surpassed only by Ken Rosewall, who won the title in 1970 at age 35. He finished the year ranked No. 8, the oldest player to finish in the top 10 since the 36-year-old Connors was No. 7 in 1988. Agassi also became only the sixth male player during the open era to reach 800 career wins with his first-round victory over Alex Bogomolov in Countrywide Classic in Los Angeles. Agassi's 2005 began with a quarterfinal loss to Federer at the Australian Open. Agassi had several other deep runs at tournaments, but had to withdraw from several events due to injury. He lost to Jarkko Nieminen in the first round of the French Open. He won his fourth title in Los Angeles and reached the final of the Rogers Cup, before falling to No. 2 Rafael Nadal. Agassi's 2005 was defined by an improbable run to the US Open final. After beating Răzvan Sabău and Ivo Karlović in straight sets and Tomáš Berdych in four sets, Agassi won three consecutive five-set matches to advance to the final. The most notable of these matches was his quarterfinal victory over James Blake, where he rallied from two sets down to win in the fifth set tie-breaker. His other five-set victims were Xavier Malisse in the fourth round and Robby Ginepri in the semifinals. In the final, Agassi faced Federer, who was seeking his second consecutive US Open title and his sixth Grand Slam title in two years. Federer defeated Agassi in four sets. Agassi finished 2005 ranked No. 7, his 16th time in the year-end top-10 rankings, which tied Connors for the most times ranked in the top 10 at year's end. Agassi had a poor start to 2006. He was still recovering from an ankle injury and also suffering from back and leg pain and lack of match play. Agassi withdrew from the Australian Open because of the ankle injury, and his back injury and other pains forced him to withdraw from several other events, eventually skipping the entire clay-court season including the French Open. This caused his ranking to drop out of the top 10 for the last time. Agassi returned for the grass-court season, playing a tune-up, and then Wimbledon. He was defeated in the third round by world No. 2 (and eventual runner-up) Rafael Nadal. Against conventions, Agassi, the losing player, was interviewed on court after the match. At Wimbledon, Agassi announced his plans to retire following the US Open. Agassi played only two events during the summer hard-court season with his best result being a quarterfinal loss at the Countrywide Classic in Los Angeles to Fernando González of Chile, which resulted in him being unseeded at the US Open. Agassi had a short, but dramatic, run in his final US Open. Because of extreme back pain, Agassi was forced to receive anti-inflammatory injections after every match. After a tough four-set win against Andrei Pavel, Agassi faced eighth-seeded Marcos Baghdatis in the second round who had earlier advanced to the 2006 Australian Open final and Wimbledon semifinals. Agassi won in five tough sets as the younger Baghdatis succumbed to muscle cramping in the final set. In his last match, Agassi fell to 112th-ranked big-serving Benjamin Becker of Germany in four sets. Agassi received a four-minute standing ovation from the crowd after the match and delivered a retirement speech. == Rivalries == === Agassi vs. Sampras === The rivalry has been considered the greatest of the generation of players competing in the 90's, as Sampras and Agassi were the most successful players of that decade. They also had very contrasting playing styles, with Sampras being considered the greatest server while Agassi the greatest serve returner of the game. Agassi and Sampras met 34 times on the tour level with Agassi trailing 14–20.The 1990 US Open was their first meeting in a Grand Slam tournament final. Agassi was favored as he was ranked No. 4 at the time, compared to the No. 12 ranking of Sampras and because Agassi had defeated Sampras in their only previously completed match. Agassi however lost the final to Sampras in straight sets. Their next meeting in a Grand Slam was at the 1992 French Open, where they met in the quarterfinals. Although Sampras was ranked higher, Agassi came out winning in straight sets. They met again on a Grand Slam level at the quarterfinals of Wimbledon in 1993, where Agassi was the defending champion and Sampras was the newly minted world No. 1. Agassi dug out from a two-nothing hole, levelling the match at 2 sets apiece, however Sampras prevailed in five sets, and went on to win his first Wimbledon championship. With both Sampras and Agassi participating, the U.S. won the Davis Cup in 1995. The year should be considered the peak of the rivalry as together they won 3 out of 4 major titles, meeting each other twice in the finals, and were occupying top two spots in the rankings for the whole year. They met 5 times during the year, all in the title matches, including the Australian Open, the Newsweek Champions Cup (now Indian Wells), the Lipton International Players Championships (now Miami Open), the Canadian Open, and the US Open. Agassi won three of the finals, including the Australian Open, however Sampras took the US Open title, ending Agassi's 26-match winning streak. After Agassi had taken most of the fall season off, Sampras took over the No. 1 ranking for the end of the season. In the following 3 years, while Sampras continued winning Grand Slam titles every season, Agassi slumped in the rankings and struggled in major competitions. The next time Sampras and Agassi met in a Grand Slam final was at Wimbledon in 1999, where Sampras won in straight sets. For both, it was considered a career rejuvenation, as Sampras had suffered a string of disappointments in the previous year while Agassi was regaining his status as a top-ranked player after winning the French Open. Sampras forfeited the No. 1 ranking to Agassi when injury forced him to withdraw from that year's US Open, which Agassi went on to win. They faced each other twice in the season-ending ATP Tour World Championships, with Sampras losing the round-robin match, but winning the final. In 2000's they met three more times on the Grand Slam level offering three memorable contests. In 2000, the top-ranked Agassi defeated No. 3 Sampras in the semifinals of the Australian Open in five sets, which was an important win for Agassi who lost 4 of the previous 5 matches against Sampras. In arguably their most memorable match ever, Sampras defeated Agassi in the 2001 US Open quarterfinals in four sets. There were no breaks of serve during the entire match. Reruns of the match are frequently featured on television, especially during US Open rain delays, and the match is considered one of the best in history because of the level of play presented by both players. Their last meeting was the final of the 2002 US Open, which was their third meeting in a US Open final, but first since 1995. The match was also notable because they had defeated several up-and-coming players en route to the final. Sampras had defeated No. 3 Tommy Haas in the fourth round and future No. 1 Andy Roddick in the quarterfinals, while Agassi had defeated No. 1 and defending champion Lleyton Hewitt in the semifinals. Sampras defeated Agassi in four sets. This was the final ATP tour singles match of Sampras's career. === Agassi vs. Chang === Michael Chang was the opponent that Agassi faced the most frequently from all the players other than Sampras. They met 22 times on the tour level with Agassi leading 15-7. Chang, unlike most of Agassi's big rivals, had a playing style similar to his. Both players preferred to dominate the game from the baseline with Chang being more defensive-minded. The outcome was that most of their meetings were built on long and entertaining rallies. The rivalry began late in the 1980s with both players being considered the prodigies of the next great generation of American tennis players, despite both having a foreign descend. Agassi won first four matches including a straight set victory in the round 16 of the 1988 US Open and defeating Chang, the defending champion, in the 1990 French Open in a 4-set quarterfinal. Arguably their best match took place in the round 16 of the 1994 US Open. While both players presented high quality shot-making, the momentum changed from set to set with Agassi eventually prevailing with a 5-set victory. It turned out to be the toughest contest on his way to his first US Open title. Their next two Grand Slam meetings came in 1996, with Chang recording easy straight set victories in semifinals of both the Australian Open and the US Open. Years after, Agassi shockingly admitted in his book, that he had lost the first of the matches on purpose as he did not want to face Boris Becker, who was awaiting the winner in the final. Agassi won the final 4 of their matches, with the last being in 2003 at the Miami Open with Chang being clearly after his prime. === Agassi vs. Becker === Boris Becker and Agassi played 14 times with Agassi leading 10–4. Becker dominated the rivalry early on, winning their first three matches in 1988 and 1989 before Agassi turned the rivalry in 1990, and won ten of their last 11 matches. They first played at Indian Wells in 1988, with Becker prevailing. Their most notable match was the 1989 Davis Cup semifinal match, which Becker won in five sets after losing the first two in tiebreaks. Agassi, considered a baseliner with a playing style not suiting grass, shocked Becker, a 3-time champion, in a five set quarterfinal at Wimbledon in 1992 on his way to his first Grand Slam title. The intensity of the rivalry peaked in 1995. Becker won that year's Wimbledon semifinal after being down a set and two breaks, to eventually win in 4 sets. In ahighly anticipated rematch in the US Open semifinal, this time it was Agassi who came out victorious in 4 tight sets. Their final match was played at Hong Kong in 1999, which Agassi won in three sets. === Agassi vs. Rafter === Agassi and Pat Rafter played fifteen times with Agassi leading 10–5. The rivalry has been considered special and delivered memorable encounters, because of the players' contrasting styles of play, with Rafter using traditional serve & volley methods against Agassi's variety of return of serves and passing shots as main weapons. Agassi led 8–2 on hard courts, but Rafter surprisingly won their sole match on clay at the 1999 Rome Masters. They played four matches at Wimbledon with both winning two matches each. Agassi won the first two in 1993 and 1999, while Rafter took their 2000 and 2001 encounters, both the gruelling 5-setters often being presented on the lists of best matches ever played. Agassi also won both their meetings at the Australian Open, in 1995 and 2001, on his way to the title in both occasions. Rafter however took their only US Open encounter in 1997 and went on to win the title. === Agassi vs. Federer === Agassi and Roger Federer played 11 times, and Federer led their head-to-head series 8–3. With the retirement of Sampras, the rivalry against 11 years younger Federer, who was another great server like Sampras, became Agassi's main rivalry for the final years of his career. Agassi won their first three matches, but then went on to lose eight consecutive ones. They first met in just the third tournament of Federer's career at the 1998 Swiss Indoors in Federer's hometown, with Agassi prevailing over the 17-year-old. Agassi also defeated Federer at the 2001 US Open and the finals of the Miami Open in 2002. Federer began to turn the tide at the Masters Cup in 2003, when he defeated Agassi in both the round robin and the final. They played a memorable quarterfinal match at the 2004 US Open that spanned over two windy days, with Federer eventually prevailing in five sets. At the 2005 Dubai Championships, Federer and Agassi attracted worldwide headlines with a publicity stunt that saw the two tennis legends play on a helipad almost 220 meters above sea level at the hotel Burj al-Arab. Their final duel took place in the final of the 2005 US Open. In the historic clash of generations, Federer was victorious in four sets in front of a pro-Agassi crowd. The match marked the last final appearance of Agassi's career. == Earnings == Agassi earned more than $30 million in prize-money during his career, sixth only to Djokovic, Federer, Nadal, Sampras and Murray to date (May 2018). He also earned more than $25 million a year through endorsements during his career, fourth in all sports at the time. == Post-retirement == Since retiring after the 2006 US Open, Agassi has participated in a series of charity tournaments and continues his work with his own charity. On September 5, 2007, he was a surprise guest commentator for the Andy Roddick/Roger Federer US Open quarterfinal. He played an exhibition match at Wimbledon, teaming with his wife, Steffi Graf, to play with Tim Henman and Kim Clijsters. He played World Team Tennis for the Philadelphia Freedoms in the summer of 2009. At the 2009 French Open, Agassi was on hand to present Roger Federer, who completed his Career Grand Slam by winning the tournament and joined Agassi as one of six men to complete the Career Grand Slam, with the trophy.Also in 2009 Agassi played at the Outback Champions Series event for the first time. He played the Cancer Treatment Centers of America Tennis Championships at Surprise, Arizona, where he reached the final before bowing to eventual champion Todd Martin. He also announced that he will not be playing the tour on a full-time basis, and played the tournament as a favor to long-time friend Jim Courier. Agassi returned to the tour renamed for the PowerShares Series in 2011 and participated in a total of seven events while winning two. Agassi beat Courier in the final of the Staples Champions Cup in Boston and later defeated Sampras at the CTCA Championships at his hometown Las Vegas.In 2012, Agassi took part in five tournaments, winning three of those. In November, at first he won BILT Champions Showdown in San Jose, beating John McEnroe in the final. The following day, he defended his title of the CTCA Championships, while defeating Courier in the decisive match. In the series season finale, he beat Michael Chang for the Acura Champions Cup. The series and Agassi came back to action in 2014. Agassi won both tournaments he participated in. At the Camden Wealth Advisors Cup's final in Houston, Agassi beat James Blake for a rematch of their 2005 US Open quarterfinal. He defeated Blake again in Portland to win the title of the Cancer Treatment Centers of America Championships. In 2015, Agassi took part in just one event of the PowerShares Series, losing to Mark Philippoussis in the final of the Champions Shootout. The following year he took part in two events, at first losing to Blake in Chicago, and the next day defeating Mardy Fish, but losing to Roddick in Charleston.In 2009, in Macau Agassi and Sampras met for the first time on court since the 2002 US Open final. Sampras won the exhibition in three sets. The rivalry between the former champions headlined sports media again in March 2010 after the two participated in the "Hit for Haiti" charity event organized to raise money for the victims of the earthquake. Partnered with Roger Federer and Rafael Nadal, the old rivals began making jokes on each other which ended up with Sampras intentionally striking a serve at Agassi's body. After the event Agassi admitted that he had crossed the line with his jokes and publicly apologized to Sampras. Agassi and Sampras met again one year later for an exhibition match at Madison Square Garden in New York in front of 19 000 spectators as Sampras defeated Agassi in two sets. On March 3, 2014, Agassi and Sampras squared off for an exhibition in London for the annual World Tennis Day. This time it was Agassi who came out on top in two straight sets.He returned to the tour in May 2017 in the position of coach to Novak Djokovic for the French Open. Agassi announced the end of the partnership on March 31, 2018, stating that there were too many disagreements in the relationship. == Playing style == Early in his career, Agassi would look to end points quickly by playing first-strike tennis, typically by inducing a weak return with a deep, hard shot, and then playing a winner at an extreme angle. His groundstrokes, return of serve, baseline game, anticipation, and eye–hand coordination were always among the best in the game. On the rare occasion that he charged the net, Agassi liked to take the ball in the air and hit a swinging volley for a winner. His favored groundstroke was his flat, accurate two-handed backhand, hit well cross-court but especially down the line. His forehand was nearly as strong, especially his inside-out to the ad court.Agassi's strength was in dictating play from the back of the court. While he was growing up, his father and Nick Bollettieri trained him in this way. When in control of a point, Agassi would often pass up an opportunity to attempt a winner and hit a conservative shot to minimize his errors, and to make his opponent run more. This change to more methodical, less aggressive baseline play was largely initiated by his longtime coach, Brad Gilbert, in their first year together in 1994. Gilbert encouraged Agassi to wear out opponents with his deep, flat groundstrokes and to use his fitness to win attrition wars, and noted Agassi's two-handed backhand down the line as his very best shot. A signature play later in his career was a change up drop shot to the deuce court after deep penetrating groundstrokes. This would often be followed by a passing shot or lob if the opponent was fast enough to retrieve it. Agassi was raised on hardcourts, but found much of his early major-tournament success on the red clay of Roland Garros, reaching two consecutive finals there early in his career. Despite grass being his worst surface, his first major win was at the slick grass of Wimbledon in 1992, a tournament that he professed to hating at the time. His strongest surface over the course of his career, was indeed hardcourt, where he won six of his eight majors. == Business ventures == Agassi established a limited liability company named Andre Agassi Ventures (formerly named Agassi Enterprises). Agassi, along with five athlete partners (including Wayne Gretzky, Joe Montana, Shaquille O'Neal, Ken Griffey, Jr., and Monica Seles) opened a chain of sports-themed restaurant named Official All Star Café in April 1996. The restaurant closed down in 2001. In 1999, he paid $1 million for a 10 percent stake in Nevada First Bank and made a $10 million profit when it was sold to Western Alliance Bancorp in 2006. In 2002, he joined the Tennis Channel to promote the channel to consumers and cable and satellite industry, and made an equity investment in the network. After meeting chef Michael Mina at one of his restaurants in San Francisco, Agassi partnered with him in 2002 to start Mina Group Inc. and opened 18 concept restaurants in San Francisco, San Jose, Dana Point, Atlantic City and Las Vegas. Agassi was an equity investor of a group that acquired Golden Nugget Las Vegas and Golden Nugget Laughlin from MGM Mirage for $215 million in 2004. One year later, the group sold the hotel-casino to Landry's, Inc. for $163 million in cash and $182 million in assumed debt. In 2007, he sat on the board of Meadows Bank, an independent bank in Nevada. He has invested in start-up companies backed by Allen & Company.Agassi and Graf formed a company called Agassi Graf Holdings. They invested in PURE, a nightclub at Caesars Palace, which opened in 2004, and sold it to Angel Management Group in 2010. In August 2006, Agassi and Graf developed a joint venture with high-end furniture maker Kreiss Enterprises. They launched a furniture line called Agassi Graf Collection. In September, Agassi and Graf, through their company Agassi Graf Development LLC, along with Bayview Financial LP, finalized an agreement to develop a condominium hotel, Fairmont Tamarack, at Tamarack Resort in Donnelly, Idaho. Due to difficult market conditions and delays, they withdrew from the project in 2009. The group still owns three small chunks of land. In September, they collaborated with Steve Case's Exclusive Resorts to co-develop luxury resorts and design Agassi-Graf Tennis and Fitness Centers.They also invested in online ticket reseller viagogo in 2009 and both serve as board members and advisors of the company.In October 2012, Village Roadshow and investors including Agassi and Graf announced plans to build new water park called Wet'n'Wild Las Vegas in Las Vegas. Village Roadshow has a 51% stake in the park while Agassi, Graf, and other private investors hold the remaining 49%. The park opened in May 2013.IMG managed Agassi from the time he turned pro in 1986 through January 2000 before switching to SFX Sports Group. His business manager, lawyer and agent was childhood friend Perry Rogers, but they have been estranged since 2008. In 2009, he and Graf signed with CAA. === Equipment and endorsements === Agassi used Prince Graphite rackets early in his career. He signed a $7 million endorsement contract with Belgian tennis racquet makers Donnay. He later switched to Head Ti Radical racket and Head's LiquidMetal Radical racket, having signed a multimillion-dollar endorsement deal with Head in 1993. He renewed his contract in 1999 and in November 2003, he signed a lifetime agreement with Head. He also endorses Penn tennis balls. On July 25, 2005, Agassi left Nike after 17 years and signed an endorsement deal with Adidas. A major reason for Agassi leaving Nike was because Nike refused to donate to Agassi's charities, and Adidas was more than happy to do so. On May 13, 2013, Agassi rejoined Nike.Agassi was sponsored by DuPont, Ebel, Mountain Dew in 1993, Mazda in 1997, Kia Motors in 2002, American Express and Deutsche Bank in 2003. In 1990, he appeared in a television commercial for Canon Inc., promoting the Canon EOS Rebel camera. Between 1999 and 2000, he signed a multimillion-dollar, multiyear endorsement deal with Schick and became the worldwide spokesman for the company. Agassi signed a multiyear contract with Twinlab and promoted the company's nutritional supplements. In mid-2003, he was named the spokesman of Aramis Life, a fragrance by Aramis and signed a five-year deal with the company. In March 2004, he signed a ten-year agreement worth $1.5 million a year with 24 Hour Fitness, which will open five Andre Agassi fitness centers by year-end. Prior to the 2012 Australian Open, Agassi and Australian winemaker Jacobs Creek announced a three-year partnership and created the Open Film Series to "[share] personal stories about the life defining moments that shaped his character on and off the court." In 2007, watchmaker Longines named Agassi as their brand ambassador.Agassi and his mother appeared in a Got Milk? advertisement in 2002. Agassi has appeared in many advertisements and television commercials with Graf. They both endorsed Deutsche Telekom in 2002, Genworth Financial and Canon Inc. in 2004, LVMH in 2007, and Nintendo Wii and Wii Fit U and Longines in 2013. == Personal life == === Relationships and family === In the early 1990s Agassi dated American entertainer Barbra Streisand. He wrote about the relationship in his 2009 autobiography, "We agree that we're good for each other, and so what if she's twenty-eight years older? We're sympatico, and the public outcry only adds spice to our connection. It makes our friendship feel forbidden, taboo – another piece of my overall rebellion. Dating Barbra Streisand is like wearing Hot Lava." He was married to Brooke Shields from 1997 to 1999.He married Steffi Graf on October 22, 2001 at their Las Vegas home; the only witnesses were their mothers. They have two children: son Jaden Gil (born 2001) and daughter Jaz Elle (born 2003). Agassi has said that he and Graf are not pushing their children toward becoming tennis players. The Graf-Agassi family resides in Summerlin, a community in the Las Vegas Valley. Graf's mother and brother, Michael, with his four children also live there.Long-time trainer Gil Reyes has been called one of Agassi's closest friends; some have described him as being a "father figure" to Agassi. In 2012, Agassi and Reyes introduced their own line of fitness equipment, BILT By Agassi and Reyes. In December 2008, Agassi's childhood friend and former business manager, Perry Rogers, sued Graf for $50,000 in management fees he claimed that she owed him. === Autobiography === Agassi's autobiography, Open: An Autobiography, (written with assistance from J. R. Moehringer), was published in November 2009. In it, Agassi admitted that he used and tested positive for methamphetamine in 1997. In response to this revelation, Roger Federer declared himself shocked and disappointed, while Marat Safin argued that Agassi should return his prize money and be stripped of his titles. In an interview with CBS, Agassi justified himself and asked for understanding, saying that, "It was a period in my life where I needed help."Agassi said that he had always hated tennis during his career because of the constant pressure it exerted on him. He also said he wore a hairpiece earlier in his career and thought Pete Sampras was "robotic". The book reached No. 1 on the New York Times Best Seller list and received favorable reviews. It won the Autobiography category of the 2010 British Sports Book Awards. == In media == In 2017, Agassi appeared in the documentary film Love Means Zero, which mentioned a troubled relationship between his coach Nick Bollettieri and him. == Politics == Agassi has donated more than $100,000 to Democratic candidates, and $2000 to Republicans. On September 1, 2010, when he appeared on daily WNYC public radio program "The Brian Lehrer Show," he stated that he is a registered Independent. == Philanthropy == Agassi founded the Andre Agassi Charitable Association in 1994, which assists Las Vegas' young people. He was awarded the ATP Arthur Ashe Humanitarian award in 1995 for his efforts to help disadvantaged youth. He is regularly cited as the most charitable and socially involved player in professional tennis. It has also been claimed that he may be the most charitable athlete of his generation.Agassi's charities help in assisting children reach their athletic potential. His Boys & Girls Club sees 2,000 children throughout the year and boasts a world-class junior tennis team. It also has a basketball program (the Agassi Stars) and a rigorous system that encourages a mix of academics and athletics. In 2001, Agassi opened the Andre Agassi College Preparatory Academy in Las Vegas, a tuition-free charter school for at-risk children in the area. He personally donated $35 million to the school. In 2009, the graduating class had 100 percent graduation rate and expected a 100 percent college acceptance rate. Among other child-related programs that Agassi supports through his Andre Agassi Charitable Foundation is Clark County's only residential facility for abused and neglected children, Child Haven. In 1997, Agassi donated funding to Child Haven for a six-room classroom building now named the Agassi Center for Education. His foundation also provided $720,000 to assist in the building of the Andre Agassi Cottage for Medically Fragile Children. This 20-bed facility opened in December 2001, and accommodates developmentally delayed or handicapped children and children quarantined for infectious diseases.In 2007, along with several other athletes, Agassi founded the charity Athletes for Hope, which helps professional athletes get involved in charitable causes and aims to inspire all people to volunteer and support their communities. He created the Canyon-Agassi Charter School Facilities Fund, now known as the Turner-Agassi Charter School Facilities Fund. The Fund is an investment initiative for social change, focusing on the "nationwide effort to move charters from stopgap buildings into permanent campuses."In September 2013, the Andre Agassi Foundation for Education formed a partnership with V20 Foods to launch Box Budd!es, a line of kids' healthy snacks. All proceeds go to the Foundation.In February 2014, Agassi remodeled the vacant University of Phoenix building as a new school called the Doral Academy West through the Canyon-Agassi Charter School Facilities Fund. Doral Academy opened in August 2014. The Fund purchased a 4.6-acre plot in Henderson, Nevada to house the Somerset Academy of Las Vegas, which will relocate from its campus inside a church. == Career statistics == === Singles timeline overview === === Grand Slam finals (8 titles, 7 runner-ups) === By winning the 1999 French Open, Agassi completed a men's singles Career Grand Slam. He is the 5th of 8 male players in history (after Budge, Perry, Laver, Emerson and before Federer, Nadal and Djokovic) to achieve this. ==== Open Era records ==== These records were attained in the Open Era of tennis and in ATP World Tour Masters 1000 series since 1990. Records in bold indicate peer-less achievements. == Professional awards == ITF World Champion: 1999. ATP Player of the Year: 1999. ATP Most Improved Player: 1988, 1998 == Recognition == In 1992, Agassi was named the BBC Overseas Sports Personality of the Year. In 2010, Sports Illustrated named Agassi the 7th greatest male player of all time. On July 9, 2011, Agassi was inducted into the International Tennis Hall of Fame at a ceremony in Newport, Rhode Island. == Video == Wimbledon 2000 Semi-final – Agassi vs. Rafter (2003) Starring: Andre Agassi, Patrick Rafter; Standing Room Only, DVD Release Date: August 16, 2005, Run Time: 213 minutes, OCLC 61774054.

### Instruction: retrieve labels for this: Afroasiatic (Afro-Asiatic), also known as Afrasian and in older sources as Hamito-Semitic (Chamito-Semitic) or Semito-Hamitic, is a large language family of about 300 languages. It includes languages spoken predominantly in West Asia, North Africa, the Horn of Africa and parts of the Sahel. Afroasiatic languages have over 495 million native speakers, the fourth largest number of any language family (after Indo-European, Sino-Tibetan and Niger–Congo). The phylum has six branches: Berber, Chadic, Cushitic, Egyptian, Omotic and Semitic. By far the most widely spoken Afroasiatic language is Arabic. A de facto group of distinct language varieties within the Semitic branch, the languages that evolved from Proto-Arabic have around 313 million native speakers, concentrated primarily in West Asia, North Africa and the Horn of Africa.Other widely spoken Afroasiatic languages include: Hausa (Chadic branch), the dominant language of northern Nigeria, Ghana, and southern Niger, spoken as a first language by over 27 million people and used as a lingua franca by another 20 million across West Africa and the Sahel Oromo (Cushitic branch), spoken in Ethiopia and Kenya by around 33 million people total Amharic (Semitic branch), spoken in Ethiopia, with over 25 million native speakers in addition to millions of other Ethiopians speaking it as a second language Somali (Cushitic branch), spoken by 15 million people in Somalia, Djibouti, eastern Ethiopia and northeastern Kenya Hebrew (Semitic branch), spoken by around 9 million people in Israel and worldwide Tigrinya (Semitic branch), spoken by around 6.9 million people in Eritrea and Ethiopia Kabyle (Berber branch), spoken by around 5 million people in Algeria. Central Atlas Tamazight (Berber branch), spoken by around 2.49 million people in Morocco Neo-Aramaic languages (Semitic branch), spoken by about 550,000 people worldwide. This is not just one language — It includes a number of subdivisions, with Assyrian Neo-Aramaic being the most spoken variety (232,300).In addition to languages spoken today, Afroasiatic includes several important ancient languages, such as Ancient Egyptian, Akkadian, Biblical Hebrew and Old Aramaic. The original homeland of the Afroasiatic family, and when the parent language (i.e. Proto-Afroasiatic) was spoken, are yet to be agreed upon by historical linguists. Proposed locations include North Africa, the Horn of Africa, the Eastern Sahara and the Levant (see below). == Etymology == During the early 1800s, linguists grouped the Berber, Cushitic and Egyptian languages within a "Hamitic" phylum, in acknowledgement of these languages' genetic relation with each other and with those in the Semitic phylum. The terms "Hamitic" and "Semitic" were etymologically derived from the Book of Genesis, which describes various Biblical tribes descended from Ham and Shem, two sons of Noah. By the 1860s, the main constituent elements within the broader Afroasiatic family had been worked out.Friedrich Müller introduced the name "Hamito-Semitic" for the entire family in his Grundriss der Sprachwissenschaft (1876). Maurice Delafosse (1914) later coined the term "Afroasiatic" (often now spelled "Afro-Asiatic"). However, it did not come into general use until Joseph Greenberg (1950) formally proposed its adoption. In doing so, Greenberg sought to emphasize the fact that Afroasiatic spanned the continents of both Africa and Asia.Individual scholars have also called the family "Erythraean" (Tucker 1966) and "Lisramic" (Hodge 1972). In lieu of "Hamito-Semitic", the Russian linguist Igor Diakonoff later suggested the term "Afrasian", meaning "half African, half Asiatic", in reference to the geographic distribution of the family's constituent languages.The term "Hamito-Semitic" remains in use in the academic traditions of some European countries. == Distribution and branches == Scholars generally treat the Afroasiatic language family as including the following branches: Berber Chadic Cushitic Egyptian Omotic SemiticAlthough there is general agreement on these six families, linguists who study Afroasiatic raise some points of disagreement, in particular: The Omotic language branch is the most controversial member of Afroasiatic, because the grammatical formatives to which most linguists have given the greatest weight in classifying languages in the family "are either absent or distinctly wobbly" (Hayward 1995). Greenberg (1963) and others considered it a subgroup of Cushitic, whereas others have raised doubts about it being part of Afroasiatic at all (e.g. Theil 2006). The Afroasiatic identity of Ongota is also broadly questioned, as is its position within Afroasiatic among those who accept it, due to the "mixed" appearance of the language and a paucity of research and data. Harold Fleming (2006) proposes that Ongota constitutes a separate branch of Afroasiatic. Bonny Sands (2009) finds the proposal by Savà and Tosco (2003) the most convincing: namely that Ongota is an East Cushitic language with a Nilo-Saharan substratum. In other words, it would appear that the Ongota people once spoke a Nilo-Saharan language but then shifted to speaking a Cushitic language but retained some characteristics of their earlier Nilo-Saharan language. Beja, sometimes listed as a separate branch of Afroasiatic, is more often included in the Cushitic branch, which has a high degree of internal diversity. Whether the various branches of Cushitic actually form a language family is sometimes questioned, but not their inclusion in Afroasiatic itself. There is no consensus on the interrelationships of the five non-Omotic branches of Afroasiatic (see § Subgrouping below). This situation is not unusual, even among long-established language families: scholars also frequently disagree on the internal classification of the Indo-European languages, for instance. Meroitic has been proposed as an unclassified Afroasiatic language, because it shares the phonotactics characteristic of the family, but there is not enough evidence to secure a classification. == Classification history == In the 9th century, the Hebrew grammarian Judah ibn Quraysh of Tiaret in Algeria was the first to link two branches of Afroasiatic together; he perceived a relationship between Berber and Semitic. He knew of Semitic through his study of Arabic, Hebrew, and Aramaic. In the course of the 19th century, Europeans also began suggesting such relationships. In 1844, Theodor Benfey suggested a language family consisting of Semitic, Berber, and Cushitic (calling the latter "Ethiopic"). In the same year, T.N. Newman suggested a relationship between Semitic and Hausa, but this would long remain a topic of dispute and uncertainty. Friedrich Müller named the traditional Hamito-Semitic family in 1876 in his Grundriss der Sprachwissenschaft ("Outline of Linguistics"), and defined it as consisting of a Semitic group plus a "Hamitic" group containing Egyptian, Berber, and Cushitic; he excluded the Chadic group. It was the Egyptologist Karl Richard Lepsius (1810–1884) who restricted Hamitic to the non-Semitic languages in Africa, which are characterized by a grammatical gender system. This "Hamitic language group" was proposed to unite various, mainly North-African, languages, including the Ancient Egyptian language, the Berber languages, the Cushitic languages, the Beja language, and the Chadic languages. Unlike Müller, Lepsius considered that Hausa and Nama were part of the Hamitic group. These classifications relied in part on non-linguistic anthropological and racial arguments. Both authors used the skin-color, mode of subsistence, and other characteristics of native speakers as part of their arguments that particular languages should be grouped together. In 1912, Carl Meinhof published Die Sprachen der Hamiten ("The Languages of the Hamites"), in which he expanded Lepsius's model, adding the Fula, Maasai, Bari, Nandi, Sandawe and Hadza languages to the Hamitic group. Meinhof's model was widely supported into the 1940s. Meinhof's system of classification of the Hamitic languages was based on a belief that "speakers of Hamitic became largely coterminous with cattle herding peoples with essentially Caucasian origins, intrinsically different from and superior to the 'Negroes of Africa'." However, in the case of the so-called Nilo-Hamitic languages (a concept he introduced), it was based on the typological feature of gender and a "fallacious theory of language mixture." Meinhof did this although earlier work by scholars such as Lepsius and Johnston had substantiated that the languages which he would later dub "Nilo-Hamitic" were in fact Nilotic languages, with numerous similarities in vocabulary to other Nilotic languages.Leo Reinisch (1909) had already proposed linking Cushitic and Chadic, while urging their more distant affinity with Egyptian and Semitic. However, his suggestion found little acceptance. Marcel Cohen (1924) rejected the idea of a distinct "Hamitic" subgroup, and included Hausa (a Chadic language) in his comparative Hamito-Semitic vocabulary. Finally, Joseph Greenberg's 1950 work led to the widespread rejection of "Hamitic" as a language category by linguists. Greenberg refuted Meinhof's linguistic theories, and rejected the use of racial and social evidence. In dismissing the notion of a separate "Nilo-Hamitic" language category in particular, Greenberg was "returning to a view widely held a half century earlier." He consequently rejoined Meinhof's so-called Nilo-Hamitic languages with their appropriate Nilotic siblings. He also added (and sub-classified) the Chadic languages, and proposed the new name Afroasiatic for the family. Almost all scholars have accepted this classification as the new and continued consensus. Greenberg's model was fully developed in his book The Languages of Africa (1963), in which he reassigned most of Meinhof's additions to Hamitic to other language families, notably Nilo-Saharan. Following Isaac Schapera and rejecting Meinhof, he classified the Khoekhoe language as a member of the Khoisan languages, a grouping that has since proven inaccurate and excessively motivated on the presence of click sounds. To Khoisan he also added the Tanzanian Hadza and Sandawe, though this view has been discredited as linguists working on these languages consider them to be linguistic isolates. Despite this, Greenberg's classification remains a starting point for modern work of many languages spoken in Africa, and the Hamitic category (and its extension to Nilo-Hamitic) has no part in this.Since the three traditional branches of the Hamitic languages (Berber, Cushitic and Egyptian) have not been shown to form an exclusive (monophyletic) phylogenetic unit of their own, separate from other Afroasiatic languages, linguists no longer use the term in this sense. Each of these branches is instead now regarded as an independent subgroup of the larger Afroasiatic family.In 1969, Harold Fleming proposed that what had previously been known as Western Cushitic is an independent branch of Afroasiatic, suggesting for it the new name Omotic. This proposal and name have met with widespread acceptance. Several scholars, including Harold Fleming and Robert Hetzron, have since questioned the traditional inclusion of Beja in Cushitic. Glottolog does not accept that the inclusion or even unity of Omotic has been established, nor that of Ongota or the unclassified Kujarge. It therefore splits off the following groups as small families: South Omotic, Mao, Dizoid, Gonga–Gimojan (North Omotic apart from the preceding), Ongota, Kujarge. === Subgrouping === Little agreement exists on the subgrouping of the five or six branches of Afroasiatic: Semitic, Egyptian, Berber, Chadic, Cushitic, and Omotic. However, Christopher Ehret (1979), Harold Fleming (1981), and Joseph Greenberg (1981) all agree that the Omotic branch split from the rest first. Otherwise: Paul Newman (1980) groups Berber with Chadic and Egyptian with Semitic, while questioning the inclusion of Omotic in Afroasiatic. Rolf Theil (2006) concurs with the exclusion of Omotic, but does not otherwise address the structure of the family. Harold Fleming (1981) divides non-Omotic Afroasiatic, or "Erythraean", into three groups, Cushitic, Semitic, and Chadic-Berber-Egyptian. He later added Semitic and Beja to Chadic-Berber-Egyptian and tentatively proposed Ongota as a new third branch of Erythraean. He thus divided Afroasiatic into two major branches, Omotic and Erythraean, with Erythraean consisting of three sub-branches, Cushitic, Chadic-Berber-Egyptian-Semitic-Beja, and Ongota. Like Harold Fleming, Christopher Ehret (1995: 490) divides Afroasiatic into two branches, Omotic and Erythrean. He divides Omotic into two branches, North Omotic and South Omotic. He divides Erythrean into Cushitic, comprising Beja, Agaw, and East-South Cushitic, and North Erythrean, comprising Chadic and "Boreafrasian." According to his classification, Boreafrasian consists of Egyptian, Berber, and Semitic. Vladimir Orel and Olga Stolbova (1995) group Berber with Semitic and Chadic with Egyptian. They split up Cushitic into five or more independent branches of Afroasiatic, viewing Cushitic as a Sprachbund rather than a language family. Igor M. Diakonoff (1996) subdivides Afroasiatic in two, grouping Berber, Cushitic, and Semitic together as East-West Afrasian (ESA), and Chadic with Egyptian as North-South Afrasian (NSA). He excludes Omotic from Afroasiatic. Lionel Bender (1997) groups Berber, Cushitic, and Semitic together as "Macro-Cushitic". He regards Chadic and Omotic as the branches of Afroasiatic most remote from the others. Alexander Militarev (2000), on the basis of lexicostatistics, groups Berber with Chadic and both more distantly with Semitic, as against Cushitic and Omotic. He places Ongota in South Omotic. == Position among the world's languages == Afroasiatic is one of the four major language families spoken in Africa identified by Joseph Greenberg in his book The Languages of Africa (1963). It is one of the few whose speech area is transcontinental, with languages from Afroasiatic's Semitic branch also spoken in the Middle East and Europe. There are no generally accepted relations between Afroasiatic and any other language family. However, several proposals grouping Afroasiatic with one or more other language families have been made. The best-known of these are the following: Hermann Möller (1906) argued for a relation between Semitic and the Indo-European languages. This proposal was accepted by a few linguists (e.g. Holger Pedersen and Louis Hjelmslev). (For a fuller account, see Indo-Semitic languages.) However, the theory has little currency today, although most linguists do not deny the existence of grammatical similarities between both families (such as grammatical gender, noun-adjective agreement, three-way number distinction, and vowel alternation as a means of derivation). Apparently influenced by Möller (a colleague of his at the University of Copenhagen), Holger Pedersen included Hamito-Semitic (the term replaced by Afroasiatic) in his proposed Nostratic macro-family (cf. Pedersen 1931:336–338), also included the Indo-European, Uralic, Altaic, Yukaghir languages, and Dravidian languages. This inclusion was retained by subsequent Nostraticists, starting with Vladislav Illich-Svitych and Aharon Dolgopolsky. Joseph Greenberg (2000–2002) did not reject a relationship of Afroasiatic to these other languages, but he considered it more distantly related to them than they were to each other, grouping instead these other languages in a separate macro-family, which he called Eurasiatic, and to which he added Chukotian, Gilyak, Korean, Japanese-Ryukyuan, Eskimo–Aleut, and Ainu. Most recently, Sergei Starostin's school has accepted Eurasiatic as a subgroup of Nostratic, with Afroasiatic, Dravidian and Kartvelian in Nostratic outside of Eurasiatic. The even larger Borean super-family contains Nostratic as well as Dené-Caucasian and Austric. == Date of Afroasiatic == The earliest written evidence of an Afroasiatic language is an Ancient Egyptian inscription dated to c. 3400 BC (5,400 years ago). Symbols on Gerzean (Naqada II) pottery resembling Egyptian hieroglyphs date back to c. 4000 BC, suggesting an earlier possible dating. This gives us a minimum date for the age of Afroasiatic. However, Ancient Egyptian is highly divergent from Proto-Afroasiatic (Trombetti 1905: 1–2), and considerable time must have elapsed in between them. Estimates of the date at which the Proto-Afroasiatic language was spoken vary widely. They fall within a range between approximately 7,500 BC (9,500 years ago), and approximately 16,000 BC (18,000 years ago). According to Igor M. Diakonoff (1988: 33n), Proto-Afroasiatic was spoken c. 10,000 BC. Christopher Ehret (2002: 35–36) asserts that Proto-Afroasiatic was spoken c. 11,000 BC at the latest, and possibly as early as c. 16,000 BC. These dates are older than those associated with other proto-languages. == Afroasiatic Urheimat == The term Afroasiatic Urheimat (Urheimat meaning "original homeland" in German) refers to the hypothetical place where Proto-Afroasiatic language speakers lived in a single linguistic community, or complex of communities, before this original language dispersed geographically and divided into distinct languages. Afroasiatic languages are today primarily spoken in West Asia, North Africa, the Horn of Africa, and parts of the Sahel. Their distribution seems to have been influenced by the Sahara pump operating over the last 10,000 years. There is no agreement when or where the original homeland of this language family existed. Proposed locations include North Africa, the Horn of Africa, the Eastern Sahara, and the Levant. == Similarities in grammar and syntax == Widespread (though not universal) features of the Afroasiatic languages include: A set of emphatic consonants, variously realized as glottalized, pharyngealized, or implosive. VSO typology with SVO tendencies. A two-gender system in the singular, with the feminine marked by the sound /t/. All Afroasiatic subfamilies show evidence of a causative affix s. Semitic, Berber, Cushitic (including Beja), and Chadic support possessive suffixes. Nisba derivation in -j (earlier Egyptian) or -ī (Semitic) Morphology in which words inflect by changes within the root (vowel changes or gemination) as well as with prefixes and suffixes.One of the most remarkable shared features among the Afroasiatic languages is the prefixing verb conjugation (see the table at the start of this section), with a distinctive pattern of prefixes beginning with /ʔ t n y/, and in particular a pattern whereby third-singular masculine /y-/ is opposed to third-singular feminine and second-singular /t-/. According to Ehret (1996), tonal languages appear in the Omotic and Chadic branches of Afroasiatic, as well as in certain Cushitic languages. The Semitic, Berber and Egyptian branches generally do not use tones phonemically. == Shared vocabulary == The following are some examples of Afroasiatic cognates, including ten pronouns, three nouns, and three verbs. Source: Christopher Ehret, Reconstructing Proto-Afroasiatic (Berkeley: University of California Press, 1995).Note: Ehret does not make use of Berber in his etymologies, stating (1995: 12): "the kind of extensive reconstruction of proto-Berber lexicon that might help in sorting through alternative possible etymologies is not yet available." The Berber cognates here are taken from previous version of table in this article and need to be completed and referenced.Abbreviations: NOm = 'North Omotic', SOm = 'South Omotic'. MSA = 'Modern South Arabian', PSC = 'Proto-Southern Cushitic', PSom-II = 'Proto-Somali, stage 2'. masc. = 'masculine', fem. = 'feminine', sing. = 'singular', pl. = 'plural'. 1s. = 'first person singular', 2s. = 'second person singular'.Symbols: Following Ehret (1995: 70), a caron ˇ over a vowel indicates rising tone, and a circumflex ^ over a vowel indicates falling tone. V indicates a vowel of unknown quality. Ɂ indicates a glottal stop. * indicates reconstructed forms based on comparison of related languages.There are two etymological dictionaries of Afroasiatic, one by Christopher Ehret, and one by Vladimir Orel and Olga Stolbova. The two dictionaries disagree on almost everything. The following table contains the thirty roots or so (out of thousands) that represent a fragile consensus of present research: === Etymological bibliography === Some of the main sources for Afroasiatic etymologies include: Cohen, Marcel. 1947.

### Instruction: retrieve labels for this: In mathematics and statistics, the arithmetic mean ( , stress on third syllable of "arithmetic"), or simply the mean or average when the context is clear, is the sum of a collection of numbers divided by the number of numbers in the collection. The collection is often a set of results of an experiment, or a set of results from a survey. The term "arithmetic mean" is preferred in some contexts in mathematics and statistics because it helps distinguish it from other means, such as the geometric mean and the harmonic mean. In addition to mathematics and statistics, the arithmetic mean is used frequently in fields such as economics, sociology, and history, and it is used in almost every academic field to some extent. For example, per capita income is the arithmetic average income of a nation's population. While the arithmetic mean is often used to report central tendencies, it is not a robust statistic, meaning that it is greatly influenced by outliers (values that are very much larger or smaller than most of the values). Notably, for skewed distributions, such as the distribution of income for which a few people's incomes are substantially greater than most people's, the arithmetic mean may not accord with one's notion of "middle", and robust statistics, such as the median, may be a better description of central tendency. == Definition == The arithmetic mean (or mean or average) is the most commonly used and readily understood measure of central tendency. In statistics, the term average refers to any of the measures of central tendency. The arithmetic mean is defined as being equal to the sum of the numerical values of each and every observation divided by the total number of observations. Symbolically, if we have a data set containing the values a 1 , a 2 , … , a n {\displaystyle a_{1},a_{2},\ldots ,a_{n}} , then the arithmetic mean A {\displaystyle A} is defined by the formula: A = 1 n ∑ i = 1 n a i = a 1 + a 2 + ⋯ + a n n {\displaystyle A={\frac {1}{n}}\sum _{i=1}^{n}a_{i}={\frac {a_{1}+a_{2}+\cdots +a_{n}}{n}}} (See summation for an explanation of the summation operator). For example, let us consider the monthly salary of 10 employees of a firm: 2500, 2700, 2400, 2300, 2550, 2650, 2750, 2450, 2600, 2400. The arithmetic mean is 2500 + 2700 + 2400 + 2300 + 2550 + 2650 + 2750 + 2450 + 2600 + 2400 10 = 2530. {\displaystyle {\frac {2500+2700+2400+2300+2550+2650+2750+2450+2600+2400}{10}}=2530.} If the data set is a statistical population (i.e., consists of every possible observation and not just a subset of them), then the mean of that population is called the population mean. If the data set is a statistical sample (a subset of the population), we call the statistic resulting from this calculation a sample mean. The arithmetic mean of a variable is often denoted by a bar, for example as in x ¯ {\displaystyle {\bar {x}}} (read x {\displaystyle x} bar), which is the mean of the n {\displaystyle n} values x 1 , x 2 , … , x n {\displaystyle x_{1},x_{2},\ldots ,x_{n}} . == Motivating properties == The arithmetic mean has several properties that make it useful, especially as a measure of central tendency. These include: If numbers x 1 , … , x n {\displaystyle x_{1},\dotsc ,x_{n}} have mean x ¯ {\displaystyle {\bar {x}}} , then ( x 1 − x ¯ ) + ⋯ + ( x n − x ¯ ) = 0 {\displaystyle (x_{1}-{\bar {x}})+\dotsb +(x_{n}-{\bar {x}})=0} . Since x i − x ¯ {\displaystyle x_{i}-{\bar {x}}} is the distance from a given number to the mean, one way to interpret this property is as saying that the numbers to the left of the mean are balanced by the numbers to the right of the mean. The mean is the only single number for which the residuals (deviations from the estimate) sum to zero. If it is required to use a single number as a "typical" value for a set of known numbers x 1 , … , x n {\displaystyle x_{1},\dotsc ,x_{n}} , then the arithmetic mean of the numbers does this best, in the sense of minimizing the sum of squared deviations from the typical value: the sum of ( x i − x ¯ ) 2 {\displaystyle (x_{i}-{\bar {x}})^{2}} . (It follows that the sample mean is also the best single predictor in the sense of having the lowest root mean squared error.) If the arithmetic mean of a population of numbers is desired, then the estimate of it that is unbiased is the arithmetic mean of a sample drawn from the population. == Contrast with median == The arithmetic mean may be contrasted with the median. The median is defined such that no more than half the values are larger than, and no more than half are smaller than, the median. If elements in the sample data increase arithmetically, when placed in some order, then the median and arithmetic average are equal. For example, consider the data sample 1 , 2 , 3 , 4 {\displaystyle {1,2,3,4}} . The average is 2.5 {\displaystyle 2.5} , as is the median. However, when we consider a sample that cannot be arranged so as to increase arithmetically, such as 1 , 2 , 4 , 8 , 16 {\displaystyle {1,2,4,8,16}} , the median and arithmetic average can differ significantly. In this case, the arithmetic average is 6.2 and the median is 4. In general, the average value can vary significantly from most values in the sample, and can be larger or smaller than most of them. There are applications of this phenomenon in many fields. For example, since the 1980s, the median income in the United States has increased more slowly than the arithmetic average of income. == Generalizations == === Weighted average === A weighted average, or weighted mean, is an average in which some data points count more strongly than others, in that they are given more weight in the calculation. For example, the arithmetic mean of 3 {\displaystyle 3} and 5 {\displaystyle 5} is ( 3 + 5 ) 2 = 4 {\displaystyle {\frac {(3+5)}{2}}=4} , or equivalently ( 1 2 ⋅ 3 ) + ( 1 2 ⋅ 5 ) = 4 {\displaystyle \left({\frac {1}{2}}\cdot 3\right)+\left({\frac {1}{2}}\cdot 5\right)=4} . In contrast, a weighted mean in which the first number receives, for example, twice as much weight as the second (perhaps because it is assumed to appear twice as often in the general population from which these numbers were sampled) would be calculated as ( 2 3 ⋅ 3 ) + ( 1 3 ⋅ 5 ) = 11 3 {\displaystyle \left({\frac {2}{3}}\cdot 3\right)+\left({\frac {1}{3}}\cdot 5\right)={\frac {11}{3}}} . Here the weights, which necessarily sum to the value one, are ( 2 / 3 ) {\displaystyle (2/3)} and ( 1 / 3 ) {\displaystyle (1/3)} , the former being twice the latter. Note that the arithmetic mean (sometimes called the "unweighted average" or "equally weighted average") can be interpreted as a special case of a weighted average in which all the weights are equal to each other (equal to 1 2 {\displaystyle {\frac {1}{2}}} in the above example, and equal to 1 n {\displaystyle {\frac {1}{n}}} in a situation with n {\displaystyle n} numbers being averaged). === Continuous probability distributions === When a population of numbers, and any sample of data from it, could take on any of a continuous range of numbers, instead of for example just integers, then the probability of a number falling into one range of possible values could differ from the probability of falling into a different range of possible values, even if the lengths of both ranges are the same. In such a case, the set of probabilities can be described using a continuous probability distribution. The analog of a weighted average in this context, in which there are an infinitude of possibilities for the precise value of the variable, is called the mean of the probability distribution. The most widely encountered probability distribution is called the normal distribution; it has the property that all measures of its central tendency, including not just the mean but also the aforementioned median and the mode, are equal to each other. This property does not hold however, in the cases of a great many probability distributions, such as the lognormal distribution illustrated here. == Angles == Particular care must be taken when using cyclic data, such as phases or angles. Naïvely taking the arithmetic mean of 1° and 359° yields a result of 180°. This is incorrect for two reasons: Firstly, angle measurements are only defined up to an additive constant of 360° (or 2π, if measuring in radians). Thus one could as easily call these 1° and −1°, or 361° and 719°, each of which gives a different average. Secondly, in this situation, 0° (equivalently, 360°) is geometrically a better average value: there is lower dispersion about it (the points are both 1° from it, and 179° from 180°, the putative average).In general application, such an oversight will lead to the average value artificially moving towards the middle of the numerical range. A solution to this problem is to use the optimization formulation (viz., define the mean as the central point: the point about which one has the lowest dispersion), and redefine the difference as a modular distance (i.e., the distance on the circle: so the modular distance between 1° and 359° is 2°, not 358°). == See also == Average Fréchet mean Generalized mean Geometric mean Harmonic mean Mode Sample mean and covariance Standard error of the mean Summary statistics == References == == Further reading == Huff, Darrell (1993).

### Instruction: retrieve labels for this: The American Football Conference (AFC) is one of the two conferences of the National Football League (NFL), the highest professional level of American football in the United States. This conference and its counterpart, the National Football Conference (NFC), currently contain 16 teams each, making up the 32 teams of the NFL. Both conferences were created as part of the 1970 merger with the rival American Football League (AFL), with all ten of the former AFL teams and three NFL teams forming the AFC, and the remaining thirteen NFL clubs forming the NFC. A series of league expansions and division realignments have occurred since the merger, thus making the current total of 16 clubs in each conference. == Current teams == Since 2002, like the NFC, the AFC has 16 teams, organized into four divisions each with four teams: East, North, South and West. == Season structure == Currently, the thirteen opponents each team faces over the 16-game regular season schedule are set using a pre-determined formula:Each AFC team plays the other teams in their respective division twice (home and away) during the regular season, in addition to 10 other games assigned to their schedule by the NFL. Two of these games are assigned on the basis of a particular team's final divisional standing from the previous season. The remaining 8 games are split between the roster of two other NFL divisions. This assignment shifts each year and will follow a standard cycle. Using the 2012 regular season schedule as an example, each team in the AFC West plays against every team in the AFC North and NFC South. In this way, non-divisional competition will be mostly among common opponents – the exception being the two games assigned based on the team's prior-season divisional standing. At the end of each season, the winner of each division, in addition to the two remaining conference teams with the highest regular season records, proceed into the playoffs. These teams consist of the four division winners and the top two wild card teams. The AFC playoffs culminate in the AFC Championship Game with the winner receiving the Lamar Hunt Trophy. The AFC Champion then plays the NFC Champion in the Super Bowl. == History == Both the AFC and the NFC were created after the NFL merged with the American Football League (AFL) in 1970. The AFL began play in 1960 with eight teams, and added two more expansion clubs (the Miami Dolphins in 1966 and the Cincinnati Bengals in 1968) before the merger. In order to equalize the number of teams in each conference, three NFL teams that predated the AFL's launch (the Cleveland Browns, Pittsburgh Steelers, and the then-Baltimore Colts) joined the ten former AFL teams to form the AFC. The two AFL divisions AFL East and AFL West were more or less intact, while the Century Division, in which the Browns and the Steelers had played since 1967, was moved from the NFL to become the new AFC Central. Since the merger, five expansion teams have joined the AFC and two have left, thus making the current total 16. When the Seattle Seahawks and the Tampa Bay Buccaneers joined the league in 1976, they were temporarily placed in the NFC and AFC respectively. This arrangement lasted for one season only before the two teams switched conferences. The Seahawks eventually returned to the NFC as a result of the 2002 realignment. The expansion Jacksonville Jaguars joined the AFC in 1995. There have been five teams that have relocated at least once. In 1984, the Baltimore Colts relocated to Indianapolis in 1984. In 1995, the Cleveland Browns had attempted to move to Baltimore; the resulting dispute between Cleveland and the team led to Modell establishing the Baltimore Ravens with the players and personnel from the Browns, while the Browns were placed in suspended operations before they were reinstated by the NFL. The Ravens were treated as an expansion team. In California, the Oakland Raiders relocated to Los Angeles in 1982, and back to Oakland in 1995, while the San Diego Chargers moved to Los Angeles in 2017. The Houston Oilers moved to Tennessee in 1997, where they were renamed the Tennessee Oilers. The team would change its name again, two years later, to the Tennessee Titans. The NFL would again expand in 2002, adding the Houston Texans to the AFC. Between 1995 and 2017, the AFC has sent less than half of the different teams with 7 of the 16 different teams to the Super Bowl. New England Patriots (9 times), Denver Broncos (4 times), Pittsburgh Steelers (4 times), Baltimore Ravens (2 times), Indianapolis Colts (2 times), Oakland Raiders (1 time), and Tennessee Titans (1 time). By contrast, the NFC has sent 13 of the 16 different teams during that same time frame with only the Detroit Lions, Minnesota Vikings, and Washington Redskins missing out on an appearance in the Super Bowl. 15 of the last 17 AFC champions have started one of just three quarterbacks - Tom Brady, Peyton Manning, and Ben Roethlisberger - in the Super Bowl. == Logo == The merged league created a new logo for the AFC that took elements of the old AFL logo, specifically the "A" and the six stars surrounding it. The AFC logo basically remained unchanged from 1970 to 2009. The 2010 NFL season introduced an updated AFC logo, with the most notable revision being the removal of two stars (leaving four representing the four divisions of the AFC), and moving the stars inside the letter, similar to the NFC logo. == References == ### Answer: <American Football League>, <National Football League>, <Organizations established in 1970>

### Instruction: retrieve labels for this: Animal Farm is an allegorical novella by George Orwell, first published in England on 17 August 1945. According to Orwell, the book reflects events leading up to the Russian Revolution of 1917 and then on into the Stalinist era of the Soviet Union. Orwell, a democratic socialist, was a critic of Joseph Stalin and hostile to Moscow-directed Stalinism, an attitude that was critically shaped by his experiences during the Spanish Civil War. The Soviet Union, he believed, had become a brutal dictatorship, built upon a cult of personality and enforced by a reign of terror. In a letter to Yvonne Davet, Orwell described Animal Farm as a satirical tale against Stalin ("un conte satirique contre Staline"), and in his essay "Why I Write" (1946), wrote that Animal Farm was the first book in which he tried, with full consciousness of what he was doing, "to fuse political purpose and artistic purpose into one whole". The original title was Animal Farm: A Fairy Story; U.S. publishers dropped the subtitle when it was published in 1946, and only one of the translations during Orwell's lifetime kept it. Other titular variations include subtitles like "A Satire" and "A Contemporary Satire". Orwell suggested the title Union des républiques socialistes animales for the French translation, which abbreviates to URSA, the Latin word for "bear", a symbol of Russia. It also played on the French name of the Soviet Union, Union des républiques socialistes soviétiques.Orwell wrote the book between November 1943 and February 1944, when the UK was in its wartime alliance with the Soviet Union and the British people and intelligentsia held Stalin in high esteem, a phenomenon Orwell hated. The manuscript was initially rejected by a number of British and American publishers, including one of Orwell's own, Victor Gollancz, which delayed its publication. It became a great commercial success when it did appear partly because international relations were transformed as the wartime alliance gave way to the Cold War.Time magazine chose the book as one of the 100 best English-language novels (1923 to 2005); it also featured at number 31 on the Modern Library List of Best 20th-Century Novels. It won a Retrospective Hugo Award in 1996, and is included in the Great Books of the Western World selection. == Plot summary == Old Major, the old boar on the Manor Farm, summons the animals on the farm together for a meeting, during which he refers to humans as "enemies" and teaches the animals a revolutionary song called "Beasts of England". When Major dies, two young pigs, Snowball and Napoleon, assume command and consider it a duty to prepare for the Rebellion. The animals revolt, driving the drunken, irresponsible farmer Mr. Jones, as well as Mrs. Jones and the other human caretakers and employees, off the farm, renaming it "Animal Farm". They adopt the Seven Commandments of Animalism, the most important of which is, "All animals are equal". Snowball teaches the animals to read and write, while Napoleon educates young puppies on the principles of Animalism. Food is plentiful, and the farm runs smoothly. The pigs elevate themselves to positions of leadership and set aside special food items, ostensibly for their personal health. Some time later, several men attack Animal Farm. Jones and his men are making an attempt to recapture the farm, aided by several other farmers who are terrified of similar animal revolts. Snowball and the animals, who are hiding in ambush, defeat the men by launching a surprise attack as soon as they enter the farmyard. Snowball's popularity soars, and this event is proclaimed "The Battle of the Cowshed". It is celebrated annually with the firing of a gun, on the anniversary of the Revolution. Napoleon and Snowball vie for pre-eminence. When Snowball announces his plans to modernize the farm by building a windmill, Napoleon has his dogs chase Snowball away and declares himself leader. Napoleon enacts changes to the governance structure of the farm, replacing meetings with a committee of pigs who will run the farm. Through a young pig named Squealer, Napoleon claims credit for the windmill idea. The animals work harder with the promise of easier lives with the windmill. When the animals find the windmill collapsed after a violent storm, Napoleon and Squealer convince the animals that Snowball is trying to sabotage their project. Once Snowball becomes a scapegoat, Napoleon begins to purge the farm with his dogs, killing animals he accuses of consorting with his old rival. When some animals recall the Battle of the Cowshed, Napoleon (who was nowhere to be found during the battle) frequently smears Snowball as a collaborator of Farmer Jones, while falsely representing himself as the hero of the battle. "Beasts of England" is replaced with an anthem glorifying Napoleon, who appears to be adopting the lifestyle of a man. The animals remain convinced that they are better off than they were under Mr. Jones. Mr. Frederick, a neighbouring farmer, attacks the farm, using blasting powder to blow up the restored windmill. Although the animals win the battle, they do so at great cost, as many, including Boxer, the workhorse, are wounded. Despite his injuries, Boxer continues working harder and harder, until he collapses while working on the windmill. Napoleon sends for a van to purportedly take Boxer to a veterinary surgeon, explaining that better care can be given there. Benjamin, the cynical donkey who "could read as well as any pig", notices that the van belongs to a knacker and attempts a futile rescue. Squealer quickly assures the animals that the van had been purchased from the knacker by an animal hospital, and the previous owner's signboard had not been repainted. In a subsequent report, Squealer reports sadly to the animals that Boxer died peacefully at the animal hospital; the pigs hold a festival one day after Boxer's death to further praise the glories of Animal Farm and have the animals work harder by taking on Boxer's ways. However, the truth was that Napoleon had engineered the sale of Boxer to the knacker, allowing him and his inner circle to acquire money to buy whisky for themselves. (In 1940s England, one way for farms to make money was to sell large animals to a knacker, who would kill the animal and boil its remains into animal glue.) Years pass, and the windmill is rebuilt along with construction of another windmill, which makes the farm a good amount of income. However, the ideals which Snowball discussed, including stalls with electric lighting, heating and running water are forgotten, with Napoleon advocating that the happiest animals live simple lives. In addition to Boxer, many of the animals who participated in the Revolution are dead, as is Farmer Jones, who died in another part of England. The pigs start to resemble humans, as they walk upright, carry whips, and wear clothes. The Seven Commandments are abridged to a single phrase: "All animals are equal, but some animals are more equal than others." Napoleon holds a dinner party for the pigs and local farmers, with whom he celebrates a new alliance. He abolishes the practice of the revolutionary traditions and restores the name "The Manor Farm". As the animals outside gaze at the scene and look from pig to man, and from man to pig, and from pig to man again, they can no longer distinguish between the two. == Characters == === Pigs === Old Major – An aged prize Middle White boar provides the inspiration that fuels the rebellion. He is an allegorical combination of Karl Marx, one of the creators of communism, and Vladimir Lenin, the communist leader of the Russian Revolution and the early Soviet nation, in that he draws up the principles of the revolution. His skull being put on revered public display recalls Lenin, whose embalmed body was put on display. Napoleon – "A large, rather fierce-looking Berkshire boar, the only Berkshire on the farm, not much of a talker, but with a reputation for getting his own way". An allegory of Joseph Stalin, Napoleon is the main villain of Animal Farm. In the first French version of Animal Farm, Napoleon is called César, the French form of Caesar, although another translation has him as Napoléon. Snowball – Napoleon's rival and original head of the farm after Jones' overthrow. He is mainly based on Leon Trotsky, but also combines elements from Lenin. Squealer – A small, white, fat porker who serves as Napoleon's second-in-command and minister of propaganda, holding a position similar to that of Vyacheslav Molotov. Minimus – A poetic pig who writes the second and third national anthems of Animal Farm after the singing of "Beasts of England" is banned. The piglets – Hinted to be the children of Napoleon and are the first generation of animals subjugated to his idea of animal inequality. The young pigs – Four pigs who complain about Napoleon's takeover of the farm but are quickly silenced and later executed, the first animals killed in Napoleon's farm purge. Based on the Great Purge of Grigori Zinoviev, Lev Kamenev, Nikolai Bukharin, and Alexei Rykov. Pinkeye – A minor pig who is mentioned only once; he is the pig that tastes Napoleon's food to make sure it is not poisoned, in response to rumours about an assassination attempt on Napoleon. === Humans === Mr. Jones – A heavy drinker who is the original owner of Manor Farm, a farm in disrepair with farmhands who often loaf on the job. He is an allegory of Russian Tsar Nicholas II, who abdicated following the February Revolution of 1917 and was murdered, along with the rest of his family, by the Bolsheviks on 17 July 1918. The animals revolt after Jones drinks so much he does not care for the animals. Mr. Frederick – The tough owner of Pinchfield, a small but well-kept neighbouring farm, who briefly enters into an alliance with Napoleon. Animal Farm shares land boundaries with Pinchfield on one side and Foxwood on another, making Animal Farm a "buffer zone" between the two bickering farmers. The animals of Animal Farm are terrified of Frederick, as rumours abound of him abusing his animals and entertaining himself with cockfighting (a likely allegory for the human rights abuses of Adolf Hitler). Napoleon enters into an alliance with Frederick in order to sell surplus timber that Pilkington also sought, but is enraged to learn Frederick paid him in counterfeit money. Shortly after the swindling, Frederick and his men invade Animal Farm, killing many animals and detonating the windmill. The brief alliance and subsequent invasion may allude to the Molotov–Ribbentrop Pact and Operation Barbarossa. Mr. Pilkington – The easy-going but crafty and well-to-do owner of Foxwood, a large neighbouring farm overgrown with weeds. Unlike Frederick, Pilkington is wealthier and owns more land, but his farm is in need of care as opposed to Frederick's smaller but more efficiently-run farm. Although on bad terms with Frederick, Pilkington is also concerned about the animal revolution that deposed Jones, and worried that this could also happen to him. Mr. Whymper – A man hired by Napoleon to act as the liaison between Animal Farm and human society. At first he is used to acquire necessities that cannot be produced on the farm, such as dog biscuits and paraffin wax, but later he procures luxuries like alcohol for the pigs. === Horses and donkeys === Boxer – A loyal, kind, dedicated, extremely strong, hard working, and respectable cart-horse, although quite naive and gullible. Boxer does a large share of the physical labour on the farm. He is shown to hold the belief that 'Napoleon is always right'. At one point, he had challenged Squealer's statement that Snowball was always against the welfare of the farm, earning him an attack from Napoleon's dogs. But Boxer's immense strength repels the attack, worrying the pigs that their authority can be challenged. Boxer has been compared to the Stakhanovite movement. He has been described as "faithful and strong"; he believes any problem can be solved if he works harder. When Boxer is injured, Napoleon sells him to a local knacker to buy himself whisky, and Squealer gives a moving account falsifying Boxer's death. Mollie – A self-centred, self-indulgent and vain young white mare who quickly leaves for another farm after the revolution. She is only once mentioned again, in a manner similar to those who left Russia after the fall of the Tsar. Clover – A gentle, caring female horse, who shows concern especially for Boxer, who often pushes himself too hard. Clover can read all the letters of the alphabet, but cannot "put words together". She seems to catch on to the sly tricks and schemes set up by Napoleon and Squealer. Benjamin – A donkey, one of the oldest, wisest animals on the farm, and one of the few who can read properly. He is sceptical, temperamental and cynical: his most frequent remark is, "Life will go on as it has always gone on—that is, badly." The academic Morris Dickstein has suggested there is "a touch of Orwell himself in this creature's timeless skepticism" and indeed, friends called Orwell "Donkey George", "after his grumbling donkey Benjamin, in Animal Farm." === Other animals === Muriel – A wise old goat who is friends with all of the animals on the farm. She, like Benjamin and Snowball, is one of the few animals on the farm who can read. The puppies – Offspring of Jessie and Bluebell, they were taken away at birth by Napoleon and reared by him to be his security force. Moses – The raven, "Mr Jones's especial pet, was a spy and a tale-bearer, but he was also a clever talker." Initially following Mrs Jones into exile, he reappears several years later and resumes his role of talking but not working. He regales Animal Farm's denizens with tales of a wondrous place beyond the clouds called "Sugarcandy Mountain, that happy country where we poor animals shall rest forever from our labours!" Orwell portrays established religion as "the black raven of priestcraft—promising pie in the sky when you die, and faithfully serving whoever happens to be in power." Napoleon brings the raven back (Ch. IX), as Stalin brought back the Russian Orthodox Church. The sheep – They show limited understanding of Animalism and the political atmosphere of the farm; yet nonetheless they blindly support Napoleon's ideals with vocal jingles during his speeches and meetings with Snowball. Some commentators have compared the sheep to representations of state controlled press. Their constant bleating of "four legs good, two legs bad" was used as a device to drown out any opposition; analogous to simplistic headlines used in printed media of the age. Towards the latter section of the book, Squealer (the propagandist) trains the sheep to alter their slogan to "four legs good, two legs better", which they dutifully do, symbolizing the state manipulation of media. The hens – The hens are promised at the start of the revolution that they will get to keep their eggs, which are stolen from them under Mr Jones. However their eggs are soon taken from them under the premise of buying goods from outside Animal Farm. The hens are among the first to rebel, albeit unsuccessfully, against Napoleon. The cows – The cows are enticed into the revolution by promises that their milk will not be stolen, but can be used to raise their own calves. Their milk is then stolen by the pigs, who learn to milk them. The milk is stirred into the pigs' mash every day, while the other animals are denied such luxuries. The cat – Never seen to carry out any work, the cat is absent for long periods and is forgiven; because her excuses are so convincing and she "purred so affectionately that it was impossible not to believe in her good intentions." She has no interest in the politics of the farm, and the only time she is recorded as having participated in an election, she is found to have actually "voted on both sides." == Composition and publication == === Origin === George Orwell wrote the manuscript in 1943 and 1944 subsequent to his experiences during the Spanish Civil War, which he described in Homage to Catalonia (1938). In the preface of a 1947 Ukrainian edition of Animal Farm, he explained how escaping the communist purges in Spain taught him "how easily totalitarian propaganda can control the opinion of enlightened people in democratic countries". This motivated Orwell to expose and strongly condemn what he saw as the Stalinist corruption of the original socialist ideals.Immediately prior to writing the book, Orwell had quit the BBC. He was also upset about a booklet for propagandists the Ministry of Information had put out. The booklet included instructions on how to quell ideological fears of the Soviet Union, such as directions to claim that the Red Terror was a figment of Nazi imagination.In the preface, Orwell also described the source of the idea of setting the book on a farm: ...I saw a little boy, perhaps ten years old, driving a huge carthorse along a narrow path, whipping it whenever it tried to turn. It struck me that if only such animals became aware of their strength we should have no power over them, and that men exploit animals in much the same way as the rich exploit the proletariat. === Efforts to find a publisher === Orwell initially encountered difficulty getting the manuscript published, largely due to fears that the book might upset the alliance between Britain, the United States, and the Soviet Union. Four publishers refused; one had initially accepted the work but declined it after consulting the Ministry of Information. Eventually, Secker and Warburg published the first edition in 1945. During the Second World War, it became clear to Orwell that anti-Soviet literature was not something which most major publishing houses would touch—including his regular publisher Gollancz. He also submitted the manuscript to Faber and Faber, where the poet T. S. Eliot (who was a director of the firm) rejected it; Eliot wrote back to Orwell praising the book's "good writing" and "fundamental integrity", but declared that they would only accept it for publication if they had some sympathy for the viewpoint "which I take to be generally Trotskyite". Eliot said he found the view "not convincing", and contended that the pigs were made out to be the best to run the farm; he posited that someone might argue "what was needed... was not more communism but more public-spirited pigs". Orwell let André Deutsch, who was working for Nicholson & Watson in 1944, read the typescript, and Deutsch was convinced that Nicholson & Watson would want to publish it; however, they did not, and "lectured Orwell on what they perceived to be errors in Animal Farm." In his London Letter on 17 April 1944 for Partisan Review, Orwell wrote that it was "now next door to impossible to get anything overtly anti-Russian printed. Anti-Russian books do appear, but mostly from Catholic publishing firms and always from a religious or frankly reactionary angle." The publisher Jonathan Cape, who had initially accepted Animal Farm, subsequently rejected the book after an official at the British Ministry of Information warned him off—although the civil servant who it is assumed gave the order was later found to be a Soviet spy. Writing to Leonard Moore, a partner in the literary agency of Christy & Moore, publisher Jonathan Cape explained that the decision had been taken on the advice of a senior official in the Ministry of Information. Such flagrant anti-Soviet bias was unacceptable, and the choice of pigs as the dominant class was thought to be especially offensive. It may reasonably be assumed that the 'important official' was a man named Peter Smollett, who was later unmasked as a Soviet agent. Orwell was suspicious of Smollett/Smolka, and he would be one of the names Orwell included in his list of Crypto-Communists and Fellow-Travellers sent to the Information Research Department in 1949. Born Hans Peter Smolka in Vienna in 1912, he came to Britain in 1933 as an NKVD agent with the codename 'Abo', became a naturalised British subject in 1938, changed his name, and after the outbreak of World War II joined the Ministry of Information where he organised pro-Soviet propaganda, working with Kim Philby in 1943–45. Smollett's family have rejected the accusation that he was a spy. The publisher wrote to Orwell, saying: If the fable were addressed generally to dictators and dictatorships at large then publication would be all right, but the fable does follow, as I see now, so completely the progress of the Russian Soviets and their two dictators [Lenin and Stalin], that it can apply only to Russia, to the exclusion of the other dictatorships. Another thing: it would be less offensive if the predominant caste in the fable were not pigs. I think the choice of pigs as the ruling caste will no doubt give offence to many people, and particularly to anyone who is a bit touchy, as undoubtedly the Russians are. Frederic Warburg also faced pressures against publication, even from people in his own office and from his wife Pamela, who felt that it was not the moment for ingratitude towards Stalin and the heroic Red Army, which had played a major part in defeating Hitler. A Russian translation was printed in the paper Posev, and in giving permission for a Russian translation of Animal Farm, Orwell refused in advance all royalties. A translation in Ukrainian, which was produced in Germany, was confiscated in large part by the American wartime authorities and handed over to the Soviet repatriation commission.In October 1945, Orwell wrote to Frederic Warburg expressing interest in pursuing the possibility that the political cartoonist David Low might illustrate Animal Farm. Low had written a letter saying that he had had "a good time with ANIMAL FARM—an excellent bit of satire—it would illustrate perfectly." Nothing came of this, and a trial issue produced by Secker & Warburg in 1956 illustrated by John Driver was abandoned, but the Folio Society published an edition in 1984 illustrated by Quentin Blake and an edition illustrated by the cartoonist Ralph Steadman was published by Secker & Warburg in 1995 to celebrate the fiftieth anniversary of the first edition of Animal Farm. === Preface === Orwell originally wrote a preface complaining about British self-censorship and how the British people were suppressing criticism of the USSR, their World War II ally: The sinister fact about literary censorship in England is that it is largely voluntary.... Things are kept right out of the British press, not because the Government intervenes but because of a general tacit agreement that 'it wouldn't do' to mention that particular fact. Although the first edition allowed space for the preface, it was not included, and as of June 2009 most editions of the book have not included it.Secker and Warburg published the first edition of Animal Farm in 1945 without an introduction. However, the publisher had provided space for a preface in the author's proof composited from the manuscript. For reasons unknown, no preface was supplied, and the page numbers had to be renumbered at the last minute.In 1972, Ian Angus found the original typescript titled "The Freedom of the Press", and Bernard Crick published it, together with his own introduction, in The Times Literary Supplement on 15 September 1972 as "How the essay came to be written". Orwell's essay criticised British self-censorship by the press, specifically the suppression of unflattering descriptions of Stalin and the Soviet government. The same essay also appeared in the Italian 1976 edition of Animal Farm with another introduction by Crick, claiming to be the first edition with the preface. Other publishers were still declining to publish it. == Critical response == Contemporary reviews of the work were not universally positive. Writing in the American New Republic magazine, George Soule expressed his disappointment in the book, writing that it "puzzled and saddened me. It seemed on the whole dull. The allegory turned out to be a creaking machine for saying in a clumsy way things that have been said better directly." Soule believed that the animals were not consistent enough with their real world inspirations, and said, "It seems to me that the failure of this book (commercially it is already assured of tremendous success) arises from the fact that the satire deals not with something the author has experienced, but rather with stereotyped ideas about a country which he probably does not know very well".The Guardian on 24 August 1945 called Animal Farm "a delightfully humorous and caustic satire on the rule of the many by the few". Tosco Fyvel, writing in Tribune on the same day, called the book "a gentle satire on a certain State and on the illusions of an age which may already be behind us." Julian Symons responded, on 7 September, "Should we not expect, in Tribune at least, acknowledgement of the fact that it is a satire not at all gentle upon a particular State—Soviet Russia? It seems to me that a reviewer should have the courage to identify Napoleon with Stalin, and Snowball with Trotsky, and express an opinion favourable or unfavourable to the author, upon a political ground. In a hundred years time perhaps, Animal Farm may be simply a fairy story, today it is a political satire with a good deal of point." Animal Farm has been subject to much comment in the decades since these early remarks. == Analysis == === Animalism === The pigs Snowball, Napoleon, and Squealer adapt Old Major's ideas into "a complete system of thought", which they formally name Animalism, an allegoric reference to Communism, not to be confused with the philosophy Animalism. Soon after, Napoleon and Squealer partake in activities associated with the humans (drinking alcohol, sleeping in beds, trading), which were explicitly prohibited by the Seven Commandments. Squealer is employed to alter the Seven Commandments to account for this humanisation, an allusion to the Soviet government's revising of history in order to exercise control of the people's beliefs about themselves and their society. The original commandments are: Whatever goes upon two legs is an enemy. Whatever goes upon four legs, or has wings, is a friend. No animal shall wear clothes. No animal shall sleep in a bed. No animal shall drink alcohol. No animal shall kill any other animal. All animals are equal.These commandments are also distilled into the maxim "Four legs good, two legs bad!" which is primarily used by the sheep on the farm, often to disrupt discussions and disagreements between animals on the nature of Animalism. Later, Napoleon and his pigs secretly revise some commandments to clear themselves of accusations of law-breaking. The changed commandments are as follows, with the changes bolded: No animal shall sleep in a bed with sheets. No animal shall drink alcohol to excess. No animal shall kill any other animal without cause. Eventually, these are replaced with the maxims, "All animals are equal, but some animals are more equal than others", and "Four legs good, two legs better!" as the pigs become more human. This is an ironic twist to the original purpose of the Seven Commandments, which were supposed to keep order within Animal Farm by uniting the animals together against the humans and preventing animals from following the humans' evil habits. Through the revision of the commandments, Orwell demonstrates how simply political dogma can be turned into malleable propaganda. === Significance and allegory === In the Eastern Bloc, both Animal Farm and later Nineteen Eighty-Four were on the list of forbidden books until the end of communist rule in 1989, and were only available via clandestine Samizdat networks.Orwell biographer Jeffrey Meyers has written, "virtually every detail has political significance in this allegory." Orwell himself wrote in 1946, "Of course I intended it primarily as a satire on the Russian revolution..[and] that kind of revolution (violent conspiratorial revolution, led by unconsciously power hungry people) can only lead to a change of masters [-] revolutions only effect a radical improvement when the masses are alert." In a preface for a 1947 Ukrainian edition, he stated, "... for the past ten years I have been convinced that the destruction of the Soviet myth was essential if we wanted a revival of the socialist movement. On my return from Spain [in 1937] I thought of exposing the Soviet myth in a story that could be easily understood by almost anyone and which could be easily translated into other languages."The revolt of the animals against Farmer Jones is Orwell's analogy with the October 1917 Bolshevik Revolution. The Battle of the Cowshed has been said to represent the allied invasion of Soviet Russia in 1918, and the defeat of the White Russians in the Russian Civil War. The pigs' rise to pre-eminence mirrors the rise of a Stalinist bureaucracy in the USSR, just as Napoleon's emergence as the farm's sole leader reflects Stalin's emergence. The pigs' appropriation of milk and apples for their own use, "the turning point of the story" as Orwell termed it in a letter to Dwight Macdonald, stands as an analogy for the crushing of the left-wing 1921 Kronstadt revolt against the Bolsheviks, and the difficult efforts of the animals to build the windmill suggest the various Five Year Plans. The puppies controlled by Napoleon parallel the nurture of the secret police in the Stalinist structure, and the pigs' treatment of the other animals on the farm recalls the internal terror faced by the populace in the 1930s. In chapter seven, when the animals confess their nonexistent crimes and are killed, Orwell directly alludes to the purges, confessions and show trials of the late 1930s. These contributed to Orwell's conviction that the Bolshevik revolution had been corrupted and the Soviet system become rotten.Peter Edgerly Firchow and Peter Davison consider that the Battle of the Windmill represents the Great Patriotic War (World War II), especially the Battle of Stalingrad and the Battle of Moscow. During the battle, Orwell first wrote, "All the animals, including Napoleon" took cover. Orwell had the publisher alter this to "All the animals except Napoleon" in recognition of Stalin's decision to remain in Moscow during the German advance. Orwell requested the change after he met Joseph Czapski in Paris in March 1945. Czapski, a survivor of the Katyn Massacre and an opponent of the Soviet regime, told Orwell, as Orwell wrote to Arthur Koestler, that it had been "the character [and] greatness of Stalin" that saved Russia from the German invasion. Other connections that writers have suggested illustrate Orwell's telescoping of Russian history from 1917 to 1943 include the wave of rebelliousness that ran through the countryside after the Rebellion, which stands for the abortive revolutions in Hungary and in Germany (Ch IV); the conflict between Napoleon and Snowball (Ch V), paralleling "the two rival and quasi-Messianic beliefs that seemed pitted against one another: Trotskyism, with its faith in the revolutionary vocation of the proletariat of the West; and Stalinism with its glorification of Russia's socialist destiny"; Napoleon's dealings with Whymper and the Willingdon markets (Ch VI), paralleling the Treaty of Rapallo; and Frederick's forged bank notes, paralleling the Hitler-Stalin non-aggression pact of August 1939, after which Frederick attacks Animal Farm without warning and destroys the windmill.The book's close, with the pigs and men in a kind of rapprochement, reflected Orwell's view of the 1943 Teheran Conference that seemed to display the establishment of "the best possible relations between the USSR and the West"—but in reality were destined, as Orwell presciently predicted, to continue to unravel. The disagreement between the allies and the start of the Cold War is suggested when Napoleon and Pilkington, both suspicious, "played an ace of spades simultaneously".Similarly, the music in the novel, starting with Beasts of England and the later anthems, parallels The Internationale and its adoption and repudiation by the Soviet authorities as the Anthem of the USSR in the 1920s and 1930s. In addition to the book's political symbolism, some critics have argued that Animal Farm can also be read as a more straightforward story about farm animals, reflecting Orwell's concern for the treatment of animals. Critics supporting such readings, beginning in the 1970s with Marxist scholar Raymond Williams and later including Jeffrey Moussaieff Masson and Helen Tiffin, cite Orwell's description of his inspiration for setting the story on a farm, in which he writes that, "from the animals’ point of view,""To them it is clear that the concept of a class struggle between humans was pure illusion, since whenever it was necessary to exploit animals, all humans united against them: the true struggle is between animals and humans." == Adaptations == === Films === Animal Farm has been adapted to film twice. Both differ from the novel and have been accused of taking significant liberties, including sanitising some aspects. Animal Farm (1954) is an animated feature in which Napoleon is apparently overthrown in a second revolution. In 1974, E. Howard Hunt revealed that he had been sent by the CIA's Psychological Warfare department to obtain the film rights from Orwell's widow, and the resulting 1954 animation was funded by the agency. Animal Farm (1999) is a TV live action version that shows Napoleon's regime collapsing in on itself, with the farm having new human owners, reflecting the collapse of Soviet communism.In 2012, a HFR-3D version of Animal Farm, potentially directed by Andy Serkis, was announced. === Radio dramatizations === A BBC radio version, produced by Rayner Heppenstall, was broadcast in January 1947. Orwell listened to the production at his home in Canonbury Square, London, with Hugh Gordon Porteous, amongst others. Orwell later wrote to Heppenstall that Porteous, "who had not read the book, grasped what was happening after a few minutes."A further radio production, again using Orwell's own dramatisation of the book, was broadcast in January 2013 on BBC Radio 4. Tamsin Greig narrated, and the cast included Nicky Henson as Napoleon, Toby Jones as the propagandist Squealer, and Ralph Ineson as Boxer. === Stage productions === A theatrical version, with music by Richard Peaslee and lyrics by Adrian Mitchell, was staged at the National Theatre London on 25 April 1984, directed by Peter Hall. It toured nine cities in 1985.A solo version, adapted and performed by Guy Masterson, premièred at the Traverse Theatre Edinburgh in January 1995 and has toured worldwide since. === Comic strip === In 1950 Norman Pett and his writing partner Don Freeman were secretly hired by the British Foreign Office to adapt Animal Farm into a comic strip. This comic was not published in the U.K., but ran in Brazilian and Burmese newspapers. == Popular culture == === Music === (Alphabetical by artist) The Boston Crusaders Drum and Bugle Corps' 2014 show was titled Animal Farm, based on the novel. Canadian-based band Boxer the Horse takes its name from a character in the novel. Dead prez based a song on their album Let's Get Free (2000), called "Animal in Man", on the novella, putting emphasis on how the other animals should not trust the pigs during a revolution. The lyrics of the song ″Arthur's Farm″ from the Half Man Half Biscuit album Back Again in the DHSS (1987) tell the story of Douglas Bader and Arthur Askey visiting Animal Farm. The song features the line "Four legs good, but no legs best" in apparent tribute to the two famous amputees. The song, "The Nature of the Beast", by the American metalcore band, Ice Nine Kills, was inspired by Animal Farm. Pink Floyd's album Animals (1977) was partially inspired by Animal Farm. It categorises people as pigs, dogs, or sheep. R.E.M.'s song "Disturbance at the Heron House" is based on Animal Farm. Radiohead's song "Optimistic" contains a lyric mentioning Animal Farm. The Clash used an image from the animated movie Animal Farm (1954) on their single "English Civil War". === Television === (Alphabetical by program) In The Daleks' Master Plan (1966), an episode of the long-running British science fiction show Doctor Who, a character references the modified seventh commandment of Animal Farm, saying: "Though we are all equal partners with the Daleks on this great conquest, some of us are more equal than others." In the tenth episode of the second season of Johnny Bravo, "Aunt Katie's Farm" (1999), Johnny, while dressed in a pig costume, yells, "Four feet good! Two feet bad!". The Lost episode "Exposé" (2007), in season three, involves flashbacks with Nikki and Paulo involving an argument with Kate about the handgun case. During this scene, Dr. Leslie Arzt yells at Kate: "The pigs are walking," a reference to Animal Farm where Napoleon and his generals begin to adapt human characteristics and change their oath from "Four legs good, two legs bad" to "Four legs good, two legs better." The seventh episode (1998) of the second season of the HBO series Oz is titled "Animal Farm" in reference to the conniving and manipulation of the characters vying for control, similar to the characters of the novella. In the ninth episode of the fourth season of Sex and the City, "Sex and the Country" (2001), Carrie goes with her new boyfriend Aidan to his cottage, and informs her friends that it reminds her of Animal Farm, and would not be surprised to hear an outburst of "four legs good, two legs bad!" In the third episode of the first season of the X-Men animated series, "Enter Magneto" (1992), Beast is seen reading a copy of Animal Farm, is mocked by the prison guards for "reading a picture book", and is asked if he "sees any relatives in there" because they assume he is an illiterate animal. === Video game === A video game adaptation of Animal Farm was announced in August 2017. Fully authorised by the estate of George Orwell, Animal Farm is created by an independent team formed specifically to deliver Orwell’s vision in an interactive format. == Editions == LCCN 46006290 (hardcover, 1946, First American Edition) ISBN 0-451-51679-6 (paperback, 1956, Signet Classic) ISBN 0-582-02173-1 (paper text, 1989) ISBN 0-15-107255-8 (hardcover, 1990) ISBN 0-582-06010-9 (paper text, 1991) ISBN 0-679-42039-8 (hardcover, 1993) ISBN 0-606-00102-6 (prebound, 1996) ISBN 0-15-100217-7 (hardcover, 1996, Anniversary Edition) ISBN 0-452-27750-7 (paperback, 1996, Anniversary Edition) ISBN 0-451-52634-1 (mass market paperback, 1996, Anniversary Edition) ISBN 0-582-53008-3 (1996) ISBN 1-56000-520-3 (cloth text, 1998, Large Type Edition) ISBN 0-7910-4774-1 (hardcover, 1999) ISBN 0-451-52536-1 (paperback, 1999) ISBN 0-7641-0819-0 (paperback, 1999) ISBN 0-8220-7009-X (e-book, 1999) ISBN 0-7587-7843-0 (hardcover, 2002) ISBN 0-15-101026-9 (hardcover, 2003, with Nineteen Eighty-Four) ISBN 0-452-28424-4 (paperback, 2003, Centennial Edition) ISBN 0-8488-0120-2 (hardcover) ISBN 0-03-055434-9 (hardcover) Animal Farm with Connections ISBN 0-395-79677-6 (hardcover) Animal Farm & Related Readings, 1997 ISBN 0-582-43447-5 (hardcover, 2007) ISBN 0-14-103349-5 (paperback, 2007) ISBN 978-0-141-03613-7 (paperback, 2008) ISBN 978-0-141-39305-6 (paperback, 2013, puffin books edition) ISBN 978-8-193-36962-3 (paperback, 2017, Pirates Enhanced Edition, India)On 17 July 2009, Amazon.com withdrew certain Amazon Kindle titles, including Animal Farm and Nineteen Eighty-Four by George Orwell, from sale, refunded buyers, and remotely deleted items from purchasers' devices after discovering that the publisher lacked rights to publish the titles in question.

### Instruction: retrieve labels for this: Alaska ( ( listen)) (Aleut: Alax̂sxax̂; Inupiaq: Alaskaq; Russian: Аляска, translit. Alyaska) is a U.S. state located in the northwest extremity of North America. The Canadian administrative divisions of British Columbia and Yukon border the state to the east, its most extreme western part is Attu Island, and it has a maritime border with Russia (Chukotka Autonomous Okrug) to the west across the Bering Strait. To the north are the Chukchi and Beaufort seas–the southern parts of the Arctic Ocean. The Pacific Ocean lies to the south and southwest. It is the largest state in the United States by area and the seventh largest subnational division in the world. In addition, it is the 3rd least populous and the most sparsely populated of the 50 United States; nevertheless, it is by far the most populous territory located mostly north of the 60th parallel in North America, its population (the total estimated at 738,432 by the U.S. Census Bureau in 2015) more than quadrupling the combined populations of Northern Canada and Greenland. Approximately half of Alaska's residents live within the Anchorage metropolitan area. Alaska's economy is dominated by the fishing, natural gas, and oil industries, resources which it has in abundance. Military bases and tourism are also a significant part of the economy. The United States purchased Alaska from the Russian Empire on March 30, 1867, for 7.2 million U.S. dollars at approximately two cents per acre ($4.74/km2). The area went through several administrative changes before becoming organized as a territory on May 11, 1912. It was admitted as the 49th state of the U.S. on January 3, 1959. == Etymology == The name "Alaska" (Russian: Аляска, tr. Alyaska) was introduced in the Russian colonial period when it was used to refer to the Alaska Peninsula. It was derived from an Aleut-language idiom, which figuratively refers to the mainland. Literally, it means object to which the action of the sea is directed. == Geography == Alaska is the northernmost and westernmost state in the United States and has the most easterly longitude in the United States because the Aleutian Islands extend into the Eastern Hemisphere. Alaska is the only non-contiguous U.S. state on continental North America; about 500 miles (800 km) of British Columbia (Canada) separates Alaska from Washington. It is technically part of the continental U.S., but is sometimes not included in colloquial use; Alaska is not part of the contiguous U.S., often called "the Lower 48". The capital city, Juneau, is situated on the mainland of the North American continent but is not connected by road to the rest of the North American highway system. The state is bordered by Yukon and British Columbia in Canada, to the east, the Gulf of Alaska and the Pacific Ocean to the south and southwest, the Bering Sea, Bering Strait, and Chukchi Sea to the west and the Arctic Ocean to the north. Alaska's territorial waters touch Russia's territorial waters in the Bering Strait, as the Russian Big Diomede Island and Alaskan Little Diomede Island are only 3 miles (4.8 km) apart. Alaska has a longer coastline than all the other U.S. states combined. Alaska is the largest state in the United States by total area at 663,268 square miles (1,717,856 km2), over twice the size of Texas, the next largest state. Alaska is larger than all but 18 sovereign countries. Counting territorial waters, Alaska is larger than the combined area of the next three largest states: Texas, California, and Montana. It is also larger than the combined area of the 22 smallest U.S. states. === Regions === There are no officially defined borders demarcating the various regions of Alaska, but there are six widely accepted regions: ==== South Central ==== The most populous region of Alaska, containing Anchorage, the Matanuska-Susitna Valley and the Kenai Peninsula. Rural, mostly unpopulated areas south of the Alaska Range and west of the Wrangell Mountains also fall within the definition of South Central, as do the Prince William Sound area and the communities of Cordova and Valdez. ==== Southeast ==== Also referred to as the Panhandle or Inside Passage, this is the region of Alaska closest to the rest of the United States. As such, this was where most of the initial non-indigenous settlement occurred in the years following the Alaska Purchase. The region is dominated by the Alexander Archipelago as well as the Tongass National Forest, the largest national forest in the United States. It contains the state capital Juneau, the former capital Sitka, and Ketchikan, at one time Alaska's largest city. The Alaska Marine Highway provides a vital surface transportation link throughout the area, as only three communities (Haines, Hyder and Skagway) enjoy direct connections to the contiguous North American road system. Officially designated in 1963. ==== Interior ==== The Interior is the largest region of Alaska; much of it is uninhabited wilderness. Fairbanks is the only large city in the region. Denali National Park and Preserve is located here. Denali is the highest mountain in North America. ==== Southwest ==== Southwest Alaska is a sparsely inhabited region stretching some 500 miles (800 km) inland from the Bering Sea. Most of the population lives along the coast. Kodiak Island is also located in Southwest. The massive Yukon–Kuskokwim Delta, one of the largest river deltas in the world, is here. Portions of the Alaska Peninsula are considered part of Southwest, with the remaining portions included with the Aleutian Islands (see below). ==== North Slope ==== The North Slope is mostly tundra peppered with small villages. The area is known for its massive reserves of crude oil, and contains both the National Petroleum Reserve–Alaska and the Prudhoe Bay Oil Field. The city of Utqiaġvik, formerly known as Barrow, is the northernmost city in the United States and is located here. The Northwest Arctic area, anchored by Kotzebue and also containing the Kobuk River valley, is often regarded as being part of this region. However, the respective Inupiat of the North Slope and of the Northwest Arctic seldom consider themselves to be one people. ==== Aleutian Islands ==== More than 300 small volcanic islands make up this chain, which stretches over 1,200 miles (1,900 km) into the Pacific Ocean. Some of these islands fall in the Eastern Hemisphere, but the International Date Line was drawn west of 180° to keep the whole state, and thus the entire North American continent, within the same legal day. Two of the islands, Attu and Kiska, were occupied by Japanese forces during World War II. === Natural features === With its myriad islands, Alaska has nearly 34,000 miles (54,720 km) of tidal shoreline. The Aleutian Islands chain extends west from the southern tip of the Alaska Peninsula. Many active volcanoes are found in the Aleutians and in coastal regions. Unimak Island, for example, is home to Mount Shishaldin, which is an occasionally smoldering volcano that rises to 10,000 feet (3,048 m) above the North Pacific. It is the most perfect volcanic cone on Earth, even more symmetrical than Japan's Mount Fuji. The chain of volcanoes extends to Mount Spurr, west of Anchorage on the mainland. Geologists have identified Alaska as part of Wrangellia, a large region consisting of multiple states and Canadian provinces in the Pacific Northwest, which is actively undergoing continent building. One of the world's largest tides occurs in Turnagain Arm, just south of Anchorage, where tidal differences can be more than 35 feet (10.7 m). Alaska has more than three million lakes. Marshlands and wetland permafrost cover 188,320 square miles (487,747 km2) (mostly in northern, western and southwest flatlands). Glacier ice covers about 28,957 square miles (75,000 km2) of Alaska. The Bering Glacier is the largest glacier in North America, covering 2,008 square miles (5,200 km2) alone. === Land ownership === According to an October 1998 report by the United States Bureau of Land Management, approximately 65% of Alaska is owned and managed by the U.S. federal government as public lands, including a multitude of national forests, national parks, and national wildlife refuges. Of these, the Bureau of Land Management manages 87 million acres (35 million hectares), or 23.8% of the state. The Arctic National Wildlife Refuge is managed by the United States Fish and Wildlife Service. It is the world's largest wildlife refuge, comprising 16 million acres (6.5 million hectares). Of the remaining land area, the state of Alaska owns 101 million acres (41 million hectares), its entitlement under the Alaska Statehood Act. A portion of that acreage is occasionally ceded to organized boroughs, under the statutory provisions pertaining to newly formed boroughs. Smaller portions are set aside for rural subdivisions and other homesteading-related opportunities. These are not very popular due to the often remote and roadless locations. The University of Alaska, as a land grant university, also owns substantial acreage which it manages independently. Another 44 million acres (18 million hectares) are owned by 12 regional, and scores of local, Native corporations created under the Alaska Native Claims Settlement Act (ANCSA) of 1971. Regional Native corporation Doyon, Limited often promotes itself as the largest private landowner in Alaska in advertisements and other communications. Provisions of ANCSA allowing the corporations' land holdings to be sold on the open market starting in 1991 were repealed before they could take effect. Effectively, the corporations hold title (including subsurface title in many cases, a privilege denied to individual Alaskans) but cannot sell the land. Individual Native allotments can be and are sold on the open market, however. Various private interests own the remaining land, totaling about one percent of the state. Alaska is, by a large margin, the state with the smallest percentage of private land ownership when Native corporation holdings are excluded. === Climate === The climate in Southeast Alaska is a mid-latitude oceanic climate (Köppen climate classification: Cfb) in the southern sections and a subarctic oceanic climate (Köppen Cfc) in the northern parts. On an annual basis, Southeast is both the wettest and warmest part of Alaska with milder temperatures in the winter and high precipitation throughout the year. Juneau averages over 50 in (130 cm) of precipitation a year, and Ketchikan averages over 150 in (380 cm). This is also the only region in Alaska in which the average daytime high temperature is above freezing during the winter months. The climate of Anchorage and south central Alaska is mild by Alaskan standards due to the region's proximity to the seacoast. While the area gets less rain than southeast Alaska, it gets more snow, and days tend to be clearer. On average, Anchorage receives 16 in (41 cm) of precipitation a year, with around 75 in (190 cm) of snow, although there are areas in the south central which receive far more snow. It is a subarctic climate (Köppen: Dfc) due to its brief, cool summers. The climate of Western Alaska is determined in large part by the Bering Sea and the Gulf of Alaska. It is a subarctic oceanic climate in the southwest and a continental subarctic climate farther north. The temperature is somewhat moderate considering how far north the area is. This region has a tremendous amount of variety in precipitation. An area stretching from the northern side of the Seward Peninsula to the Kobuk River valley (i. e., the region around Kotzebue Sound) is technically a desert, with portions receiving less than 10 in (25 cm) of precipitation annually. On the other extreme, some locations between Dillingham and Bethel average around 100 in (250 cm) of precipitation.The climate of the interior of Alaska is subarctic. Some of the highest and lowest temperatures in Alaska occur around the area near Fairbanks. The summers may have temperatures reaching into the 90s °F (the low-to-mid 30s °C), while in the winter, the temperature can fall below −60 °F (−51 °C). Precipitation is sparse in the Interior, often less than 10 in (25 cm) a year, but what precipitation falls in the winter tends to stay the entire winter. The highest and lowest recorded temperatures in Alaska are both in the Interior. The highest is 100 °F (38 °C) in Fort Yukon (which is just 8 mi or 13 km inside the arctic circle) on June 27, 1915, making Alaska tied with Hawaii as the state with the lowest high temperature in the United States. The lowest official Alaska temperature is −80 °F (−62 °C) in Prospect Creek on January 23, 1971, one degree above the lowest temperature recorded in continental North America (in Snag, Yukon, Canada).The climate in the extreme north of Alaska is Arctic (Köppen: ET) with long, very cold winters and short, cool summers. Even in July, the average low temperature in Barrow is 34 °F (1 °C). Precipitation is light in this part of Alaska, with many places averaging less than 10 in (25 cm) per year, mostly as snow which stays on the ground almost the entire year. == History == === Pre-colonization === Numerous indigenous peoples occupied Alaska for thousands of years before the arrival of European peoples to the area. Linguistic and DNA studies done here have provided evidence for the settlement of North America by way of the Bering land bridge. At the Upward Sun River site in the Tanana River Valley in Alaska, remains of a six-week-old infant were found. The baby’s DNA showed that she belonged to a population that was genetically separate from other native groups present elsewhere in the New World at the end of the Pleistocene. Ben Potter, the University of Alaska Fairbanks archaeologist who unearthed the remains at the Upward River Sun site in 2013, named this new group Ancient Beringians. The Tlingit people developed a society with a matrilineal kinship system of property inheritance and descent in what is today Southeast Alaska, along with parts of British Columbia and the Yukon. Also in Southeast were the Haida, now well known for their unique arts. The Tsimshian people came to Alaska from British Columbia in 1887, when President Grover Cleveland, and later the U.S. Congress, granted them permission to settle on Annette Island and found the town of Metlakatla. All three of these peoples, as well as other indigenous peoples of the Pacific Northwest Coast, experienced smallpox outbreaks from the late 18th through the mid-19th century, with the most devastating epidemics occurring in the 1830s and 1860s, resulting in high fatalities and social disruption.The Aleutian Islands are still home to the Aleut people's seafaring society, although they were the first Native Alaskans to be exploited by Russians. Western and Southwestern Alaska are home to the Yup'ik, while their cousins the Alutiiq ~ Sugpiaq lived in what is now Southcentral Alaska. The Gwich'in people of the northern Interior region are Athabaskan and primarily known today for their dependence on the caribou within the much-contested Arctic National Wildlife Refuge. The North Slope and Little Diomede Island are occupied by the widespread Inupiat people. === Colonization === Some researchers believe that the first Russian settlement in Alaska was established in the 17th century. According to this hypothesis, in 1648 several koches of Semyon Dezhnyov's expedition came ashore in Alaska by storm and founded this settlement. This hypothesis is based on the testimony of Chukchi geographer Nikolai Daurkin, who had visited Alaska in 1764–1765 and who had reported on a village on the Kheuveren River, populated by "bearded men" who "pray to the icons". Some modern researchers associate Kheuveren with Koyuk River.The first European vessel to reach Alaska is generally held to be the St. Gabriel under the authority of the surveyor M. S. Gvozdev and assistant navigator I. Fyodorov on August 21, 1732, during an expedition of Siberian cossak A. F. Shestakov and Belorussian explorer Dmitry Pavlutsky (1729–1735).Another European contact with Alaska occurred in 1741, when Vitus Bering led an expedition for the Russian Navy aboard the St. Peter. After his crew returned to Russia with sea otter pelts judged to be the finest fur in the world, small associations of fur traders began to sail from the shores of Siberia toward the Aleutian Islands. The first permanent European settlement was founded in 1784. Between 1774 and 1800, Spain sent several expeditions to Alaska in order to assert its claim over the Pacific Northwest. In 1789 a Spanish settlement and fort were built in Nootka Sound. These expeditions gave names to places such as Valdez, Bucareli Sound, and Cordova. Later, the Russian-American Company carried out an expanded colonization program during the early-to-mid-19th century. Sitka, renamed New Archangel from 1804 to 1867, on Baranof Island in the Alexander Archipelago in what is now Southeast Alaska, became the capital of Russian America. It remained the capital after the colony was transferred to the United States. The Russians never fully colonized Alaska, and the colony was never very profitable. Evidence of Russian settlement in names and churches survive throughout southeast Alaska. William H. Seward, the United States Secretary of State, negotiated the Alaska Purchase (also known as Seward's Folly) with the Russians in 1867 for $7.2 million. Alaska was loosely governed by the military initially, and was administered as a district starting in 1884, with a governor appointed by the President of the United States. A federal district court was headquartered in Sitka. For most of Alaska's first decade under the United States flag, Sitka was the only community inhabited by American settlers. They organized a "provisional city government," which was Alaska's first municipal government, but not in a legal sense. Legislation allowing Alaskan communities to legally incorporate as cities did not come about until 1900, and home rule for cities was extremely limited or unavailable until statehood took effect in 1959. === Territory === Starting in the 1890s and stretching in some places to the early 1910s, gold rushes in Alaska and the nearby Yukon Territory brought thousands of miners and settlers to Alaska. Alaska was officially incorporated as an organized territory in 1912. Alaska's capital, which had been in Sitka until 1906, was moved north to Juneau. Construction of the Alaska Governor's Mansion began that same year. European immigrants from Norway and Sweden also settled in southeast Alaska, where they entered the fishing and logging industries. During World War II, the Aleutian Islands Campaign focused on the three outer Aleutian Islands – Attu, Agattu and Kiska – that were invaded by Japanese troops and occupied between June 1942 and August 1943. During the occupation, one Aleut civilian was killed by Japanese troops and nearly fifty were interned in Japan, where about half of them died. Unalaska/Dutch Harbor became a significant base for the United States Army Air Forces and Navy submariners. The United States Lend-Lease program involved the flying of American warplanes through Canada to Fairbanks and then Nome; Soviet pilots took possession of these aircraft, ferrying them to fight the German invasion of the Soviet Union. The construction of military bases contributed to the population growth of some Alaskan cities. === Statehood === Statehood for Alaska was an important cause of James Wickersham early in his tenure as a congressional delegate. Decades later, the statehood movement gained its first real momentum following a territorial referendum in 1946. The Alaska Statehood Committee and Alaska's Constitutional Convention would soon follow. Statehood supporters also found themselves fighting major battles against political foes, mostly in the U.S. Congress but also within Alaska. Statehood was approved by Congress on July 7, 1958. Alaska was officially proclaimed a state on January 3, 1959. In 1960, the Census Bureau reported Alaska's population as 77.2% White, 3% Black, and 18.8% American Indian and Alaska Native. === Good Friday earthquake === On March 27, 1964, the massive Good Friday earthquake killed 133 people and destroyed several villages and portions of large coastal communities, mainly by the resultant tsunamis and landslides. It was the second-most-powerful earthquake in the recorded history of the world, with a moment magnitude of 9.2. It was over one thousand times more powerful than the 1989 San Francisco earthquake. The time of day (5:36 pm), time of year and location of the epicenter were all cited as factors in potentially sparing thousands of lives, particularly in Anchorage. === Discovery of oil === The 1968 discovery of oil at Prudhoe Bay and the 1977 completion of the Trans-Alaska Pipeline System led to an oil boom. Royalty revenues from oil have funded large state budgets from 1980 onward. That same year, not coincidentally, Alaska repealed its state income tax. In 1989, the Exxon Valdez hit a reef in the Prince William Sound, spilling over 11 million U.S. gallons (42 megaliters) of crude oil over 1,100 miles (1,800 km) of coastline. Today, the battle between philosophies of development and conservation is seen in the contentious debate over oil drilling in the Arctic National Wildlife Refuge and the proposed Pebble Mine. === Alaska Heritage Resources Survey === The Alaska Heritage Resources Survey (AHRS) is a restricted inventory of all reported historic and prehistoric sites within the state of Alaska; it is maintained by the Office of History and Archaeology. The survey's inventory of cultural resources includes objects, structures, buildings, sites, districts, and travel ways, with a general provision that they are over 50 years old. As of January 31, 2012, over 35,000 sites have been reported. == Demographics == The United States Census Bureau estimates that the population of Alaska was 738,432 on July 1, 2015, a 3.97% increase since the 2010 United States Census.In 2010, Alaska ranked as the 47th state by population, ahead of North Dakota, Vermont, and Wyoming (and Washington, D.C.). Estimates show North Dakota ahead as of 2017. Alaska is the least densely populated state, and one of the most sparsely populated areas in the world, at 1.2 inhabitants per square mile (0.46/km2), with the next state, Wyoming, at 5.8 inhabitants per square mile (2.2/km2). Alaska is the largest U.S. state by area, and the tenth wealthiest (per capita income). As of November 2014, the state's unemployment rate was 6.6%. As of 2018, it is one of 14 U.S. states that still has only one telephone area code. === Race and Ethnicity === According to the 2010 United States Census, Alaska, had a population of 710,231. In terms of race and ethnicity, the state was 66.7% White (64.1% Non-Hispanic White), 14.8% American Indian and Alaska Native, 5.4% Asian, 3.3% Black or African American, 1.0% Native Hawaiian and Other Pacific Islander, 1.6% from Some Other Race, and 7.3% from Two or More Races. Hispanics or Latinos of any race made up 5.5% of the population.As of 2011, 50.7% of Alaska's population younger than one year of age belonged to minority groups (i.e., did not have two parents of non-Hispanic white ancestry). === Languages === According to the 2011 American Community Survey, 83.4% of people over the age of five speak only English at home. About 3.5% speak Spanish at home. About 2.2% speak another Indo-European language at home and about 4.3% speak an Asian language (including Tagalog) at home. About 5.3% speak other languages at home.The Alaska Native Language Center at the University of Alaska Fairbanks claims that at least 20 Alaskan native languages exist and there are also some languages with different dialects. Most of Alaska's native languages belong to either the Eskimo–Aleut or Na-Dene language families however some languages are thought to be isolates (e.g. Haida) or have not yet been classified (e.g. Tsimshianic). As of 2014 nearly all of Alaska's native languages were classified as either threatened, shifting, moribund, nearly extinct, or dormant languages.A total of 5.2% of Alaskans speak one of the state's 20 indigenous languages, known locally as "native languages". In October 2014, the governor of Alaska signed a bill declaring the state's 20 indigenous languages as official languages. This bill gave the languages symbolic recognition as official languages, though they have not been adopted for official use within the government. The 20 languages that were included in the bill are: Inupiaq Siberian Yupik Central Alaskan Yup'ik Alutiiq Unangax Dena'ina Deg Xinag Holikachuk Koyukon Upper Kuskokwim Gwich'in Tanana Upper Tanana Tanacross Hän Ahtna Eyak Tlingit Haida Tsimshian === Religion === According to statistics collected by the Association of Religion Data Archives from 2010, about 34% of Alaska residents were members of religious congregations. 100,960 people identified as Evangelical Protestants, 50,866 as Roman Catholic, and 32,550 as mainline Protestants. Roughly 4% are Mormon, 0.5% are Jewish, 1% are Muslim, 0.5% are Buddhist, and 0.5% are Hindu. The largest religious denominations in Alaska as of 2010 were the Catholic Church with 50,866 adherents, non-denominational Evangelical Protestants with 38,070 adherents, The Church of Jesus Christ of Latter-day Saints with 32,170 adherents, and the Southern Baptist Convention with 19,891 adherents. Alaska has been identified, along with Pacific Northwest states Washington and Oregon, as being the least religious states of the USA, in terms of church membership.In 1795, the First Russian Orthodox Church was established in Kodiak. Intermarriage with Alaskan Natives helped the Russian immigrants integrate into society. As a result, an increasing number of Russian Orthodox churches gradually became established within Alaska. Alaska also has the largest Quaker population (by percentage) of any state. In 2009 there were 6,000 Jews in Alaska (for whom observance of halakha may pose special problems). Alaskan Hindus often share venues and celebrations with members of other Asian religious communities, including Sikhs and Jains.Estimates for the number of Muslims in Alaska range from 2,000 to 5,000. The Islamic Community Center of Anchorage began efforts in the late 1990s to construct a mosque in Anchorage. They broke ground on a building in south Anchorage in 2010 and were nearing completion in late 2014. When completed, the mosque will be the first in the state and one of the northernmost mosques in the world. == Economy == The 2007 gross state product was $44.9 billion, 45th in the nation. Its per capita personal income for 2007 was $40,042, ranking 15th in the nation. According to a 2013 study by Phoenix Marketing International, Alaska had the fifth-largest number of millionaires per capita in the United States, with a ratio of 6.75 percent. The oil and gas industry dominates the Alaskan economy, with more than 80% of the state's revenues derived from petroleum extraction. Alaska's main export product (excluding oil and natural gas) is seafood, primarily salmon, cod, Pollock and crab. Agriculture represents a very small fraction of the Alaskan economy. Agricultural production is primarily for consumption within the state and includes nursery stock, dairy products, vegetables, and livestock. Manufacturing is limited, with most foodstuffs and general goods imported from elsewhere. Employment is primarily in government and industries such as natural resource extraction, shipping, and transportation. Military bases are a significant component of the economy in the Fairbanks North Star, Anchorage and Kodiak Island boroughs, as well as Kodiak. Federal subsidies are also an important part of the economy, allowing the state to keep taxes low. Its industrial outputs are crude petroleum, natural gas, coal, gold, precious metals, zinc and other mining, seafood processing, timber and wood products. There is also a growing service and tourism sector. Tourists have contributed to the economy by supporting local lodging. === Energy === Alaska has vast energy resources, although its oil reserves have been largely depleted. Major oil and gas reserves were found in the Alaska North Slope (ANS) and Cook Inlet basins, but according to the Energy Information Administration, by February 2014 Alaska had fallen to fourth place in the nation in crude oil production after Texas, North Dakota, and California. Prudhoe Bay on Alaska's North Slope is still the second highest-yielding oil field in the United States, typically producing about 400,000 barrels per day (64,000 m3/d), although by early 2014 North Dakota's Bakken Formation was producing over 900,000 barrels per day (140,000 m3/d). Prudhoe Bay was the largest conventional oil field ever discovered in North America, but was much smaller than Canada's enormous Athabasca oil sands field, which by 2014 was producing about 1,500,000 barrels per day (240,000 m3/d) of unconventional oil, and had hundreds of years of producible reserves at that rate.The Trans-Alaska Pipeline can transport and pump up to 2.1 million barrels (330,000 m3) of crude oil per day, more than any other crude oil pipeline in the United States. Additionally, substantial coal deposits are found in Alaska's bituminous, sub-bituminous, and lignite coal basins. The United States Geological Survey estimates that there are 85.4 trillion cubic feet (2,420 km3) of undiscovered, technically recoverable gas from natural gas hydrates on the Alaskan North Slope. Alaska also offers some of the highest hydroelectric power potential in the country from its numerous rivers. Large swaths of the Alaskan coastline offer wind and geothermal energy potential as well. Alaska's economy depends heavily on increasingly expensive diesel fuel for heating, transportation, electric power and light. Though wind and hydroelectric power are abundant and underdeveloped, proposals for statewide energy systems (e.g. with special low-cost electric interties) were judged uneconomical (at the time of the report, 2001) due to low (less than 50¢/gal) fuel prices, long distances and low population. The cost of a gallon of gas in urban Alaska today is usually 30–60¢ higher than the national average; prices in rural areas are generally significantly higher but vary widely depending on transportation costs, seasonal usage peaks, nearby petroleum development infrastructure and many other factors. ==== Permanent Fund ==== The Alaska Permanent Fund is a constitutionally authorized appropriation of oil revenues, established by voters in 1976 to manage a surplus in state petroleum revenues from oil, largely in anticipation of the then recently constructed Trans-Alaska Pipeline System. The fund was originally proposed by Governor Keith Miller on the eve of the 1969 Prudhoe Bay lease sale, out of fear that the legislature would spend the entire proceeds of the sale (which amounted to $900 million) at once. It was later championed by Governor Jay Hammond and Kenai state representative Hugh Malone. It has served as an attractive political prospect ever since, diverting revenues which would normally be deposited into the general fund. The Alaska Constitution was written so as to discourage dedicating state funds for a particular purpose. The Permanent Fund has become the rare exception to this, mostly due to the political climate of distrust existing during the time of its creation. From its initial principal of $734,000, the fund has grown to $50 billion as a result of oil royalties and capital investment programs. Most if not all the principal is invested conservatively outside Alaska. This has led to frequent calls by Alaskan politicians for the Fund to make investments within Alaska, though such a stance has never gained momentum. Starting in 1982, dividends from the fund's annual growth have been paid out each year to eligible Alaskans, ranging from an initial $1,000 in 1982 (equal to three years' payout, as the distribution of payments was held up in a lawsuit over the distribution scheme) to $3,269 in 2008 (which included a one-time $1,200 "Resource Rebate"). Every year, the state legislature takes out 8% from the earnings, puts 3% back into the principal for inflation proofing, and the remaining 5% is distributed to all qualifying Alaskans. To qualify for the Permanent Fund Dividend, one must have lived in the state for a minimum of 12 months, maintain constant residency subject to allowable absences, and not be subject to court judgments or criminal convictions which fall under various disqualifying classifications or may subject the payment amount to civil garnishment. The Permanent Fund is often considered to be one of the leading examples of a "Basic Income" policy in the world. === Cost of living === The cost of goods in Alaska has long been higher than in the contiguous 48 states. Federal government employees, particularly United States Postal Service (USPS) workers and active-duty military members, receive a Cost of Living Allowance usually set at 25% of base pay because, while the cost of living has gone down, it is still one of the highest in the country.Rural Alaska suffers from extremely high prices for food and consumer goods compared to the rest of the country, due to the relatively limited transportation infrastructure. === Agriculture and fishing === Due to the northern climate and short growing season, relatively little farming occurs in Alaska. Most farms are in either the Matanuska Valley, about 40 miles (64 km) northeast of Anchorage, or on the Kenai Peninsula, about 60 miles (97 km) southwest of Anchorage. The short 100-day growing season limits the crops that can be grown, but the long sunny summer days make for productive growing seasons. The primary crops are potatoes, carrots, lettuce, and cabbage. The Tanana Valley is another notable agricultural locus, especially the Delta Junction area, about 100 miles (160 km) southeast of Fairbanks, with a sizable concentration of farms growing agronomic crops; these farms mostly lie north and east of Fort Greely. This area was largely set aside and developed under a state program spearheaded by Hammond during his second term as governor. Delta-area crops consist predominantly of barley and hay. West of Fairbanks lies another concentration of small farms catering to restaurants, the hotel and tourist industry, and community-supported agriculture. Alaskan agriculture has experienced a surge in growth of market gardeners, small farms and farmers' markets in recent years, with the highest percentage increase (46%) in the nation in growth in farmers' markets in 2011, compared to 17% nationwide. The peony industry has also taken off, as the growing season allows farmers to harvest during a gap in supply elsewhere in the world, thereby filling a niche in the flower market. Alaska, with no counties, lacks county fairs. However, a small assortment of state and local fairs (with the Alaska State Fair in Palmer the largest), are held mostly in the late summer. The fairs are mostly located in communities with historic or current agricultural activity, and feature local farmers exhibiting produce in addition to more high-profile commercial activities such as carnival rides, concerts and food. "Alaska Grown" is used as an agricultural slogan. Alaska has an abundance of seafood, with the primary fisheries in the Bering Sea and the North Pacific. Seafood is one of the few food items that is often cheaper within the state than outside it. Many Alaskans take advantage of salmon seasons to harvest portions of their household diet while fishing for subsistence, as well as sport. This includes fish taken by hook, net or wheel.Hunting for subsistence, primarily caribou, moose, and Dall sheep is still common in the state, particularly in remote Bush communities. An example of a traditional native food is Akutaq, the Eskimo ice cream, which can consist of reindeer fat, seal oil, dried fish meat and local berries. Alaska's reindeer herding is concentrated on Seward Peninsula, where wild caribou can be prevented from mingling and migrating with the domesticated reindeer.Most food in Alaska is transported into the state from "Outside", and shipping costs make food in the cities relatively expensive. In rural areas, subsistence hunting and gathering is an essential activity because imported food is prohibitively expensive. Though most small towns and villages in Alaska lie along the coastline, the cost of importing food to remote villages can be high, because of the terrain and difficult road conditions, which change dramatically, due to varying climate and precipitation changes. The cost of transport can reach as high as 50¢ per pound ($1.10/kg) or more in some remote areas, during the most difficult times, if these locations can be reached at all during such inclement weather and terrain conditions. The cost of delivering a 1 US gallon (3.8 L) of milk is about $3.50 in many villages where per capita income can be $20,000 or less. Fuel cost per gallon is routinely 20–30¢ higher than the continental United States average, with only Hawaii having higher prices. == Transportation == === Roads === Alaska has few road connections compared to the rest of the U.S. The state's road system covers a relatively small area of the state, linking the central population centers and the Alaska Highway, the principal route out of the state through Canada. The state capital, Juneau, is not accessible by road, only a car ferry, which has spurred several debates over the decades about moving the capital to a city on the road system, or building a road connection from Haines. The western part of Alaska has no road system connecting the communities with the rest of Alaska. One unique feature of the Alaska Highway system is the Anton Anderson Memorial Tunnel, an active Alaska Railroad tunnel recently upgraded to provide a paved roadway link with the isolated community of Whittier on Prince William Sound to the Seward Highway about 50 miles (80 km) southeast of Anchorage at Portage. At 2.5 miles (4.0 km), the tunnel was the longest road tunnel in North America until 2007. The tunnel is the longest combination road and rail tunnel in North America. === Rail === Built around 1915, the Alaska Railroad (ARR) played a key role in the development of Alaska through the 20th century. It links north Pacific shipping through providing critical infrastructure with tracks that run from Seward to Interior Alaska by way of South Central Alaska, passing through Anchorage, Eklutna, Wasilla, Talkeetna, Denali, and Fairbanks, with spurs to Whittier, Palmer and North Pole. The cities, towns, villages, and region served by ARR tracks are known statewide as "The Railbelt". In recent years, the ever-improving paved highway system began to eclipse the railroad's importance in Alaska's economy. The railroad played a vital role in Alaska's development, moving freight into Alaska while transporting natural resources southward (i.e., coal from the Usibelli coal mine near Healy to Seward and gravel from the Matanuska Valley to Anchorage). It is well known for its summertime tour passenger service. The Alaska Railroad was one of the last railroads in North America to use cabooses in regular service and still uses them on some gravel trains. It continues to offer one of the last flag stop routes in the country. A stretch of about 60 miles (100 km) of track along an area north of Talkeetna remains inaccessible by road; the railroad provides the only transportation to rural homes and cabins in the area. Until construction of the Parks Highway in the 1970s, the railroad provided the only land access to most of the region along its entire route. In northern Southeast Alaska, the White Pass and Yukon Route also partly runs through the state from Skagway northwards into Canada (British Columbia and Yukon Territory), crossing the border at White Pass Summit. This line is now mainly used by tourists, often arriving by cruise liner at Skagway. It was featured in the 1983 BBC television series Great Little Railways. The Alaska Rail network is not connected to Outside. In 2000, the U.S. Congress authorized $6 million to study the feasibility of a rail link between Alaska, Canada, and the lower 48.Alaska Rail Marine provides car float service between Whittier and Seattle. === Marine transport === Many cities, towns and villages in the state do not have road or highway access; the only modes of access involve travel by air, river, or the sea. Alaska's well-developed state-owned ferry system (known as the Alaska Marine Highway) serves the cities of southeast, the Gulf Coast and the Alaska Peninsula. The ferries transport vehicles as well as passengers. The system also operates a ferry service from Bellingham, Washington and Prince Rupert, British Columbia, in Canada through the Inside Passage to Skagway. The Inter-Island Ferry Authority also serves as an important marine link for many communities in the Prince of Wales Island region of Southeast and works in concert with the Alaska Marine Highway. In recent years, cruise lines have created a summertime tourism market, mainly connecting the Pacific Northwest to Southeast Alaska and, to a lesser degree, towns along Alaska's gulf coast. The population of Ketchikan may rise by over 10,000 people on many days during the summer, as up to four large cruise ships at a time can dock, debarking thousands of passengers. === Air transport === Cities not served by road, sea, or river can be reached only by air, foot, dogsled, or snowmachine, accounting for Alaska's extremely well developed bush air services—an Alaskan novelty. Anchorage and, to a lesser extent Fairbanks, is served by many major airlines. Because of limited highway access, air travel remains the most efficient form of transportation in and out of the state. Anchorage recently completed extensive remodeling and construction at Ted Stevens Anchorage International Airport to help accommodate the upsurge in tourism (in 2012–2013, Alaska received almost 2 million visitors).Regular flights to most villages and towns within the state that are commercially viable are challenging to provide, so they are heavily subsidized by the federal government through the Essential Air Service program. Alaska Airlines is the only major airline offering in-state travel with jet service (sometimes in combination cargo and passenger Boeing 737-400s) from Anchorage and Fairbanks to regional hubs like Bethel, Nome, Kotzebue, Dillingham, Kodiak, and other larger communities as well as to major Southeast and Alaska Peninsula communities. The bulk of remaining commercial flight offerings come from small regional commuter airlines such as Ravn Alaska, PenAir, and Frontier Flying Service. The smallest towns and villages must rely on scheduled or chartered bush flying services using general aviation aircraft such as the Cessna Caravan, the most popular aircraft in use in the state. Much of this service can be attributed to the Alaska bypass mail program which subsidizes bulk mail delivery to Alaskan rural communities. The program requires 70% of that subsidy to go to carriers who offer passenger service to the communities. Many communities have small air taxi services. These operations originated from the demand for customized transport to remote areas. Perhaps the most quintessentially Alaskan plane is the bush seaplane. The world's busiest seaplane base is Lake Hood, located next to Ted Stevens Anchorage International Airport, where flights bound for remote villages without an airstrip carry passengers, cargo, and many items from stores and warehouse clubs. In 2006 Alaska had the highest number of pilots per capita of any U.S. state. === Other transport === Another Alaskan transportation method is the dogsled. In modern times (that is, any time after the mid-late 1920s), dog mushing is more of a sport than a true means of transportation. Various races are held around the state, but the best known is the Iditarod Trail Sled Dog Race, a 1,150-mile (1,850 km) trail from Anchorage to Nome (although the distance varies from year to year, the official distance is set at 1,049 miles or 1,688 km). The race commemorates the famous 1925 serum run to Nome in which mushers and dogs like Togo and Balto took much-needed medicine to the diphtheria-stricken community of Nome when all other means of transportation had failed. Mushers from all over the world come to Anchorage each March to compete for cash, prizes, and prestige. The "Serum Run" is another sled dog race that more accurately follows the route of the famous 1925 relay, leaving from the community of Nenana (southwest of Fairbanks) to Nome.In areas not served by road or rail, primary transportation in summer is by all-terrain vehicle and in winter by snowmobile or "snow machine," as it is commonly referred to in Alaska. === Data transport === Alaska's internet and other data transport systems are provided largely through the two major telecommunications companies: GCI and Alaska Communications. GCI owns and operates what it calls the Alaska United Fiber Optic system and as of late 2011 Alaska Communications advertised that it has "two fiber optic paths to the lower 48 and two more across Alaska. In January 2011, it was reported that a $1 billion project to connect Asia and rural Alaska was being planned, aided in part by $350 million in stimulus from the federal government. == Law and government == === State government === Like all other U.S. states, Alaska is governed as a republic, with three branches of government: an executive branch consisting of the Governor of Alaska and the other independently elected constitutional officers; a legislative branch consisting of the Alaska House of Representatives and Alaska Senate; and a judicial branch consisting of the Alaska Supreme Court and lower courts. The state of Alaska employs approximately 16,000 people statewide.The Alaska Legislature consists of a 40-member House of Representatives and a 20-member Senate. Senators serve four-year terms and House members two. The Governor of Alaska serves four-year terms. The lieutenant governor runs separately from the governor in the primaries, but during the general election, the nominee for governor and nominee for lieutenant governor run together on the same ticket. Alaska's court system has four levels: the Alaska Supreme Court, the Alaska Court of Appeals, the superior courts and the district courts. The superior and district courts are trial courts. Superior courts are courts of general jurisdiction, while district courts only hear certain types of cases, including misdemeanor criminal cases and civil cases valued up to $100,000.The Supreme Court and the Court of Appeals are appellate courts. The Court of Appeals is required to hear appeals from certain lower-court decisions, including those regarding criminal prosecutions, juvenile delinquency, and habeas corpus. The Supreme Court hears civil appeals and may in its discretion hear criminal appeals. === State politics === Although in its early years of statehood Alaska was a Democratic state, since the early 1970s it has been characterized as Republican-leaning. Local political communities have often worked on issues related to land use development, fishing, tourism, and individual rights. Alaska Natives, while organized in and around their communities, have been active within the Native corporations. These have been given ownership over large tracts of land, which require stewardship. Alaska was formerly the only state in which possession of one ounce or less of marijuana in one's home was completely legal under state law, though the federal law remains in force.The state has an independence movement favoring a vote on secession from the United States, with the Alaskan Independence Party.Six Republicans and four Democrats have served as governor of Alaska. In addition, Republican Governor Wally Hickel was elected to the office for a second term in 1990 after leaving the Republican party and briefly joining the Alaskan Independence Party ticket just long enough to be reelected. He officially rejoined the Republican party in 1994. Alaska's voter initiative making marijuana legal took effect on February 24, 2015, placing Alaska alongside Colorado and Washington as the first three U.S. states where recreational marijuana is legal. The new law means people over age 21 can consume small amounts of pot – if they can find it. There is a rather lengthy and involved application process, per Alaska Measure 2 (2014). The first legal marijuana store opened in Valdez in October 2016. === Taxes === To finance state government operations, Alaska depends primarily on petroleum revenues and federal subsidies. This allows it to have the lowest individual tax burden in the United States. It is one of five states with no state sales tax, one of seven states that do not levy an individual income tax, and one of the two states that has neither. The Department of Revenue Tax Division reports regularly on the state's revenue sources. The Department also issues an annual summary of its operations, including new state laws that directly affect the tax division. While Alaska has no state sales tax, 89 municipalities collect a local sales tax, from 1.0–7.5%, typically 3–5%. Other local taxes levied include raw fish taxes, hotel, motel, and bed-and-breakfast 'bed' taxes, severance taxes, liquor and tobacco taxes, gaming (pull tabs) taxes, tire taxes and fuel transfer taxes. A part of the revenue collected from certain state taxes and license fees (such as petroleum, aviation motor fuel, telephone cooperative) is shared with municipalities in Alaska. Fairbanks has one of the highest property taxes in the state as no sales or income taxes are assessed in the Fairbanks North Star Borough (FNSB). A sales tax for the FNSB has been voted on many times, but has yet to be approved, leading lawmakers to increase taxes dramatically on goods such as liquor and tobacco. In 2014 the Tax Foundation ranked Alaska as having the fourth most "business friendly" tax policy, behind only Wyoming, South Dakota, and Nevada. === Federal politics === Alaska regularly supports Republicans in presidential elections and has done so since statehood. Republicans have won the state's electoral college votes in all but one election that it has participated in (1964). No state has voted for a Democratic presidential candidate fewer times. Alaska was carried by Democratic nominee Lyndon B. Johnson during his landslide election in 1964, while the 1960 and 1968 elections were close. Since 1972, however, Republicans have carried the state by large margins. In 2008, Republican John McCain defeated Democrat Barack Obama in Alaska, 59.49% to 37.83%. McCain's running mate was Sarah Palin, the state's governor and the first Alaskan on a major party ticket. Obama lost Alaska again in 2012, but he captured 40% of the state's vote in that election, making him the first Democrat to do so since 1968. The Alaska Bush, central Juneau, midtown and downtown Anchorage, and the areas surrounding the University of Alaska Fairbanks campus and Ester have been strongholds of the Democratic Party. The Matanuska-Susitna Borough, the majority of Fairbanks (including North Pole and the military base), and South Anchorage typically have the strongest Republican showing. As of 2004, well over half of all registered voters have chosen "Non-Partisan" or "Undeclared" as their affiliation, despite recent attempts to close primaries to unaffiliated voters. Because of its population relative to other U.S. states, Alaska has only one member in the U.S. House of Representatives. This seat is held by Republican Don Young, who was re-elected to his 21st consecutive term in 2012. Alaska's at-large congressional district is one of the largest parliamentary constituencies in the world by area. In 2008, Governor Sarah Palin became the first Republican woman to run on a national ticket when she became John McCain's running mate. She continued to be a prominent national figure even after resigning from the governor's job in July 2009.Alaska's United States Senators belong to Class 2 and Class 3. In 2008, Democrat Mark Begich, mayor of Anchorage, defeated long-time Republican senator Ted Stevens. Stevens had been convicted on seven felony counts of failing to report gifts on Senate financial discloser forms one week before the election. The conviction was set aside in April 2009 after evidence of prosecutorial misconduct emerged. Republican Frank Murkowski held the state's other senatorial position. After being elected governor in 2002, he resigned from the Senate and appointed his daughter, State Representative Lisa Murkowski as his successor. She won full six-year terms in 2004 and 2010. Alaska's current statewide elected officials == Cities, towns and boroughs == Alaska is not divided into counties, as most of the other U.S. states, but it is divided into boroughs. Many of the more densely populated parts of the state are part of Alaska's 16 boroughs, which function somewhat similarly to counties in other states. However, unlike county-equivalents in the other 49 states, the boroughs do not cover the entire land area of the state. The area not part of any borough is referred to as the Unorganized Borough. The Unorganized Borough has no government of its own, but the U.S. Census Bureau in cooperation with the state divided the Unorganized Borough into 11 census areas solely for the purposes of statistical analysis and presentation. A recording district is a mechanism for administration of the public record in Alaska. The state is divided into 34 recording districts which are centrally administered under a State Recorder. All recording districts use the same acceptance criteria, fee schedule, etc., for accepting documents into the public record.Whereas many U.S. states use a three-tiered system of decentralization—state/county/township—most of Alaska uses only two tiers—state/borough. Owing to the low population density, most of the land is located in the Unorganized Borough. As the name implies, it has no intermediate borough government but is administered directly by the state government. In 2000, 57.71% of Alaska's area has this status, with 13.05% of the population.Anchorage merged the city government with the Greater Anchorage Area Borough in 1975 to form the Municipality of Anchorage, containing the city proper and the communities of Eagle River, Chugiak, Peters Creek, Girdwood, Bird, and Indian. Fairbanks has a separate borough (the Fairbanks North Star Borough) and municipality (the City of Fairbanks).The state's most populous city is Anchorage, home to 278,700 people in 2006, 225,744 of whom live in the urbanized area. The richest location in Alaska by per capita income is Halibut Cove ($89,895). Yakutat City, Sitka, Juneau, and Anchorage are the four largest cities in the U.S. by area. === Cities and census-designated places (by population) === As reflected in the 2010 United States Census, Alaska has a total of 355 incorporated cities and census-designated places (CDPs). The tally of cities includes four unified municipalities, essentially the equivalent of a consolidated city–county. The majority of these communities are located in the rural expanse of Alaska known as "The Bush" and are unconnected to the contiguous North American road network. The table at the bottom of this section lists the 100 largest cities and census-designated places in Alaska, in population order. Of Alaska's 2010 Census population figure of 710,231, 20,429 people, or 2.88% of the population, did not live in an incorporated city or census-designated place. Approximately three-quarters of that figure were people who live in urban and suburban neighborhoods on the outskirts of the city limits of Ketchikan, Kodiak, Palmer and Wasilla. CDPs have not been established for these areas by the United States Census Bureau, except that seven CDPs were established for the Ketchikan-area neighborhoods in the 1980 Census (Clover Pass, Herring Cove, Ketchikan East, Mountain Point, North Tongass Highway, Pennock Island and Saxman East), but have not been used since. The remaining population was scattered throughout Alaska, both within organized boroughs and in the Unorganized Borough, in largely remote areas. == Education == The Alaska Department of Education and Early Development administers many school districts in Alaska. In addition, the state operates a boarding school, Mt. Edgecumbe High School in Sitka, and provides partial funding for other boarding schools, including Nenana Student Living Center in Nenana and The Galena Interior Learning Academy in Galena.There are more than a dozen colleges and universities in Alaska. Accredited universities in Alaska include the University of Alaska Anchorage, University of Alaska Fairbanks, University of Alaska Southeast, and Alaska Pacific University. Alaska is the only state that has no institutions that are part of NCAA Division I. The Alaska Department of Labor and Workforce Development operates AVTEC, Alaska's Institute of Technology. Campuses in Seward and Anchorage offer 1 week to 11-month training programs in areas as diverse as Information Technology, Welding, Nursing, and Mechanics. Alaska has had a problem with a "brain drain". Many of its young people, including most of the highest academic achievers, leave the state after high school graduation and do not return. As of 2013, Alaska did not have a law school or medical school. The University of Alaska has attempted to combat this by offering partial four-year scholarships to the top 10% of Alaska high school graduates, via the Alaska Scholars Program. == Public health and public safety == The Alaska State Troopers are Alaska's statewide police force. They have a long and storied history, but were not an official organization until 1941. Before the force was officially organized, law enforcement in Alaska was handled by various federal agencies. Larger towns usually have their own local police and some villages rely on "Public Safety Officers" who have police training but do not carry firearms. In much of the state, the troopers serve as the only police force available. In addition to enforcing traffic and criminal law, wildlife Troopers enforce hunting and fishing regulations. Due to the varied terrain and wide scope of the Troopers' duties, they employ a wide variety of land, air, and water patrol vehicles. Many rural communities in Alaska are considered "dry," having outlawed the importation of alcoholic beverages. Suicide rates for rural residents are higher than urban.Domestic abuse and other violent crimes are also at high levels in the state; this is in part linked to alcohol abuse. Alaska has the highest rate of sexual assault in the nation, especially in rural areas. The average age of sexually assaulted victims is 16 years old. In four out of five cases, the suspects were relatives, friends or acquaintances. == Culture == Some of Alaska's popular annual events are the Iditarod Trail Sled Dog Race that starts in Anchorage and ends in Nome, World Ice Art Championships in Fairbanks, the Blueberry Festival and Alaska Hummingbird Festival in Ketchikan, the Sitka Whale Fest, and the Stikine River Garnet Fest in Wrangell. The Stikine River attracts the largest springtime concentration of American bald eagles in the world. The Alaska Native Heritage Center celebrates the rich heritage of Alaska's 11 cultural groups. Their purpose is to encourage cross-cultural exchanges among all people and enhance self-esteem among Native people. The Alaska Native Arts Foundation promotes and markets Native art from all regions and cultures in the State, using the internet. === Music === Influences on music in Alaska include the traditional music of Alaska Natives as well as folk music brought by later immigrants from Russia and Europe. Prominent musicians from Alaska include singer Jewel, traditional Aleut flautist Mary Youngblood, folk singer-songwriter Libby Roderick, Christian music singer-songwriter Lincoln Brewster, metal/post hardcore band 36 Crazyfists and the groups Pamyua and Portugal. The Man. There are many established music festivals in Alaska, including the Alaska Folk Festival, the Fairbanks Summer Arts Festival, the Anchorage Folk Festival, the Athabascan Old-Time Fiddling Festival, the Sitka Jazz Festival, and the Sitka Summer Music Festival. The most prominent orchestra in Alaska is the Anchorage Symphony Orchestra, though the Fairbanks Symphony Orchestra and Juneau Symphony are also notable. The Anchorage Opera is currently the state's only professional opera company, though there are several volunteer and semi-professional organizations in the state as well. The official state song of Alaska is "Alaska's Flag", which was adopted in 1955; it celebrates the flag of Alaska. === Alaska in film and on television === Alaska's first independent picture entirely made in Alaska was The Chechahcos, produced by Alaskan businessman Austin E. Lathrop and filmed in and around Anchorage. Released in 1924 by the Alaska Moving Picture Corporation, it was the only film the company made. One of the most prominent movies filmed in Alaska is MGM's Eskimo/Mala The Magnificent, starring Alaska Native Ray Mala. In 1932 an expedition set out from MGM's studios in Hollywood to Alaska to film what was then billed as "The Biggest Picture Ever Made." Upon arriving in Alaska, they set up "Camp Hollywood" in Northwest Alaska, where they lived during the duration of the filming. Louis B. Mayer spared no expense in spite of the remote location, going so far as to hire the chef from the Hotel Roosevelt in Hollywood to prepare meals. When Eskimo premiered at the Astor Theatre in New York City, the studio received the largest amount of feedback in its history to that point. Eskimo was critically acclaimed and released worldwide; as a result, Mala became an international movie star. Eskimo won the first Oscar for Best Film Editing at the Academy Awards, and showcased and preserved aspects of Inupiat culture on film. The 1983 Disney movie Never Cry Wolf was at least partially shot in Alaska. The 1991 film White Fang, based on Jack London's novel and starring Ethan Hawke, was filmed in and around Haines. Steven Seagal's 1994 On Deadly Ground, starring Michael Caine, was filmed in part at the Worthington Glacier near Valdez. The 1999 John Sayles film Limbo, starring David Strathairn, Mary Elizabeth Mastrantonio, and Kris Kristofferson, was filmed in Juneau. The psychological thriller Insomnia, starring Al Pacino and Robin Williams, was shot in Canada, but was set in Alaska. The 2007 film directed by Sean Penn, Into The Wild, was partially filmed and set in Alaska. The film, which is based on the novel of the same name, follows the adventures of Christopher McCandless, who died in a remote abandoned bus along the Stampede Trail west of Healy in 1992. Many films and television shows set in Alaska are not filmed there; for example, Northern Exposure, set in the fictional town of Cicely, Alaska, was filmed in Roslyn, Washington. The 2007 horror feature 30 Days of Night is set in Barrow, but was filmed in New Zealand. Many reality television shows are filmed in Alaska. In 2011 the Anchorage Daily News found ten set in the state. == State symbols == State motto: North to the Future Nicknames: "The Last Frontier" or "Land of the Midnight Sun" or "Seward's Icebox" State bird: willow ptarmigan, adopted by the Territorial Legislature in 1955. It is a small (15–17 in or 380–430 mm) Arctic grouse that lives among willows and on open tundra and muskeg. Plumage is brown in summer, changing to white in winter. The willow ptarmigan is common in much of Alaska. State fish: king salmon, adopted 1962. State flower: wild/native forget-me-not, adopted by the Territorial Legislature in 1917.

### Instruction: retrieve labels for this: Aldous Leonard Huxley (26 July 1894 – 22 November 1963) was an English writer, novelist, philosopher, and prominent member of the Huxley family. He graduated from Balliol College at the University of Oxford with a first-class honours degree in English literature. The author of nearly fifty books, Huxley was best known for his novels (among them Brave New World, set in a dystopian future); for nonfiction works, such as The Doors of Perception, in which he recalls his experiences taking psychedelic drugs; and for his wide-ranging essays. Early in his career, Huxley published short stories and poetry, and edited the literary magazine Oxford Poetry. He went on to publish travel writing, film stories, satire, and screenplays. He spent the latter part of his life in the United States, living in Los Angeles from 1937 until his death.Huxley was a humanist and pacifist. He became interested in spiritual subjects such as parapsychology and philosophical mysticism, and in particular universalism. By the end of his life, Huxley was widely acknowledged as one of the pre-eminent intellectuals of his time. He was nominated for the Nobel Prize in Literature seven times. In 1962, a year before he died, Huxley was elected Companion of Literature by the Royal Society of Literature. == Early life == Huxley was born in Godalming, Surrey, England, in 1894. He was the third son of the writer and schoolmaster Leonard Huxley, who edited Cornhill Magazine, and his first wife, Julia Arnold, who founded Prior's Field School. Julia was the niece of poet and critic Matthew Arnold and the sister of Mrs. Humphry Ward. Aldous was the grandson of Thomas Henry Huxley, the zoologist, agnostic, and controversialist ("Darwin's Bulldog"). His brother Julian Huxley and half-brother Andrew Huxley also became outstanding biologists. Aldous had another brother, Noel Trevelyan Huxley (1891–1914), who committed suicide after a period of clinical depression.As a child, Huxley's nickname was "Ogie," short for "Ogre." He was described by his brother, Julian, as someone who frequently "[contemplated] the strangeness of things". According to his cousin and contemporary, Gervas Huxley, he had an early interest in drawing.Huxley's education began in his father's well-equipped botanical laboratory, after which he enrolled at Hillside School near Godalming. He was taught there by his own mother for several years until she became terminally ill. After Hillside, he went on to Eton College. His mother died in 1908 when he was 14. In 1911 he contracted the eye disease (keratitis punctata) which "left [him] practically blind for two to three years." This "ended his early dreams of becoming a doctor." In October 1913, Huxley entered Balliol College, Oxford, where he studied English literature. In January 1916, he volunteered for the British Army in the Great War, however was rejected on health grounds, being half-blind in one eye. His eyesight later partly recovered. In 1916 he edited Oxford Poetry and in June of that year graduated BA with first class honours. His brother Julian wrote: I believe his blindness was a blessing in disguise. For one thing, it put paid to his idea of taking up medicine as a career ... His uniqueness lay in his universalism. He was able to take all knowledge for his province. Following his years at Balliol, Huxley, being financially indebted to his father, decided to find employment. From April to July 1917, he was in charge of ordering supplies at the Air Ministry . He taught French for a year at Eton, where Eric Blair (who was to take the pen name George Orwell) and Steven Runciman were among his pupils. He was mainly remembered as being an incompetent schoolmaster unable to keep order in class. Nevertheless, Blair and others spoke highly of his excellent command of language.Significantly, Huxley also worked for a time during the 1920s at Brunner and Mond, an advanced chemical plant in Billingham in County Durham, northeast England. According to the introduction to the latest edition of his science fiction novel Brave New World (1932), the experience he had there of "an ordered universe in a world of planless incoherence" was an important source for the novel. == Career == Huxley completed his first (unpublished) novel at the age of 17 and began writing seriously in his early 20s, establishing himself as a successful writer and social satirist. His first published novels were social satires, Crome Yellow (1921), Antic Hay (1923), Those Barren Leaves (1925), and Point Counter Point (1928). Brave New World was Huxley's fifth novel and first dystopian work. In the 1920s he was also a contributor to Vanity Fair and British Vogue magazines. === Bloomsbury Set === During World War I, Huxley spent much of his time at Garsington Manor near Oxford, home of Lady Ottoline Morrell, working as a farm labourer. There he met several Bloomsbury figures, including Bertrand Russell, Alfred North Whitehead, and Clive Bell. Later, in Crome Yellow (1921) he caricatured the Garsington lifestyle. Jobs were very scarce, but in 1919 John Middleton Murry was reorganising the Athenaeum and invited Huxley to join the staff. He accepted immediately, and quickly married the Belgian refugee Maria Nys, also at Garsington. They lived with their young son in Italy part of the time during the 1920s, where Huxley would visit his friend D. H. Lawrence. Following Lawrence's death in 1930, Huxley edited Lawrence's letters (1932).Works of this period included important novels on the dehumanising aspects of scientific progress, most famously Brave New World, and on pacifist themes (for example, Eyeless in Gaza). In Brave New World, set in a dystopian London, Huxley portrays a society operating on the principles of mass production and Pavlovian conditioning. Huxley was strongly influenced by F. Matthias Alexander and included him as a character in Eyeless in Gaza. Starting from this period, Huxley began to write and edit non-fiction works on pacifist issues, including Ends and Means, An Encyclopedia of Pacifism, and Pacifism and Philosophy, and was an active member of the Peace Pledge Union. === United States === In 1937 Huxley moved to Hollywood with his wife Maria, son Matthew Huxley, and friend Gerald Heard. He lived in the U.S., mainly in southern California, until his death, and also for a time in Taos, New Mexico, where he wrote Ends and Means (published in 1937). The book contains tracts on war, religion, nationalism and ethics. Heard introduced Huxley to Vedanta (Upanishad-centered philosophy), meditation, and vegetarianism through the principle of ahimsa. In 1938, Huxley befriended Jiddu Krishnamurti, whose teachings he greatly admired. Huxley and Krishnamurti entered into an enduring exchange (sometimes edging on debate) over many years, with Krishnamurti representing the more rarefied, detached, ivory-tower perspective and Huxley, with his pragmatic concerns, the more socially and historically informed position. Huxley provided an introduction to Krishnamurti's quintessential statement, The First and Last Freedom (1954).Huxley also became a Vedantist in the circle of Hindu Swami Prabhavananda, and introduced Christopher Isherwood to this circle. Not long after, Huxley wrote his book on widely held spiritual values and ideas, The Perennial Philosophy, which discussed the teachings of renowned mystics of the world. Huxley's book affirmed a sensibility that insists there are realities beyond the generally accepted "five senses" and that there is genuine meaning for humans beyond both sensual satisfactions and sentimentalities. Huxley became a close friend of Remsen Bird, president of Occidental College. He spent much time at the college, which is in the Eagle Rock neighbourhood of Los Angeles. The college appears as "Tarzana College" in his satirical novel After Many a Summer (1939). The novel won Huxley a British literary award, the 1939 James Tait Black Memorial Prize for fiction. Huxley also incorporated Bird into the novel. During this period, Huxley earned a substantial income as a Hollywood screenwriter; Christopher Isherwood, in his autobiography My Guru and His Disciple, states that Huxley earned more than $3,000 per week (an enormous sum in those days) as a screenwriter, and that he used much of it to transport Jewish and left-wing writer and artist refugees from Hitler's Germany to the U.S. In March 1938, his friend Anita Loos, a novelist and screenwriter, put him in touch with Metro-Goldwyn-Mayer who hired Huxley for Madame Curie, which was originally to star Greta Garbo and be directed by George Cukor. (Eventually, the film was completed by MGM in 1943 with a different director and cast.) Huxley received screen credit for Pride and Prejudice (1940) and was paid for his work on a number of other films, including Jane Eyre (1944). Huxley was commissioned by Walt Disney in 1945 to write a script based on Alice's Adventures in Wonderland and the biography of the story's author, Lewis Carroll. The script was not used, however.Huxley wrote an introduction to the posthumous publication of J. D. Unwin's 1940 book Hopousia or The Sexual and Economic Foundations of a New Society.On 21 October 1949, Huxley wrote to George Orwell, author of Nineteen Eighty-Four, congratulating him on "how fine and how profoundly important the book is." In his letter to Orwell, he predicted: Within the next generation I believe that the world's leaders will discover that infant conditioning and narco-hypnosis are more efficient, as instruments of government, than clubs and prisons, and that the lust for power can be just as completely satisfied by suggesting people into loving their servitude as by flogging them and kicking them into obedience. Huxley had deeply felt apprehensions about the future the developed world might make for itself. From these, he made some warnings in his writings and talks. In a 1958 televised interview conducted by journalist Mike Wallace, Huxley outlined several major concerns: the difficulties and dangers of world overpopulation; the tendency toward distinctly hierarchical social organisation; the crucial importance of evaluating the use of technology in mass societies susceptible to wily persuasion; the tendency to promote modern politicians to a naive public as well-marketed commodities. === Post World War II === In 1953 Huxley and Maria applied for United States citizenship and presented themselves for examination. When Huxley refused to bear arms for the U.S. and would not state that his objections were based on religious ideals, the only excuse allowed under the McCarran Act, the judge had to adjourn the proceedings. He withdrew his application. Nevertheless, he remained in the U.S. In 1959 Huxley turned down an offer of a Knight Bachelor by the Macmillan government without putting forward a reason; his brother Julian had been knighted in 1958, while another brother Andrew would be knighted in 1974. == Association with Vedanta == Beginning in 1939 and continuing until his death in 1963, Huxley had an extensive association with the Vedanta Society of Southern California, founded and headed by Swami Prabhavananda. Together with Gerald Heard, Christopher Isherwood, and other followers he was initiated by the Swami and was taught meditation and spiritual practices.In 1944 Huxley wrote the introduction to the "Bhagavad Gita: The Song of God", translated by Swami Prabhavananda and Christopher Isherwood, which was published by the Vedanta Society of Southern California. From 1941 until 1960, Huxley contributed 48 articles to Vedanta and the West, published by the society. He also served on the editorial board with Isherwood, Heard, and playwright John van Druten from 1951 through 1962. Huxley also occasionally lectured at the Hollywood and Santa Barbara Vedanta temples. Two of those lectures have been released on CD: Knowledge and Understanding and Who Are We? from 1955. Nonetheless, Huxley's agnosticism, together with his speculative propensity, made it difficult for him to fully embrace any form of institutionalised religion.In the spring of 1953, Huxley had his first experience with psychedelic drugs, in this case, mescaline. Huxley had initiated a correspondence with Dr. Humphry Osmond, a British psychiatrist then employed in a Canadian institution, and eventually asked him to supply a dose of mescaline; Osmond obliged and supervised Huxley's session in southern California. After the publication of The Doors of Perception, in which he recounted this experience, Huxley and Swami Prabhavananda disagreed about the meaning and importance of the psychedelic drug experience, which may have caused the relationship to cool, but Huxley continued to write articles for the society's journal, lecture at the temple, and attend social functions. == Eyesight == There are differing accounts about the details of the quality of Huxley's eyesight at specific points in his life. About 1939 Huxley encountered the Bates method for better eyesight, and a teacher, Margaret Darst Corbett, who was able to teach the method to him. In 1940, Huxley relocated from Hollywood to a 40-acre (16 ha) ranchito in the high desert hamlet of Llano, California, in northern Los Angeles County. Huxley then said that his sight improved dramatically with the Bates Method and the extreme and pure natural lighting of the southwestern American desert. He reported that, for the first time in more than 25 years, he was able to read without glasses and without strain. He even tried driving a car along the dirt road beside the ranch. He wrote a book about his successes with the Bates Method, The Art of Seeing, which was published in 1942 (U.S.), 1943 (UK). The book contained some generally disputed theories, and its publication created a growing degree of popular controversy about Huxley's eyesight.It was, and is, widely believed that Huxley was nearly blind since the illness in his teens, despite the partial recovery that had enabled him to study at Oxford. For example, some ten years after publication of The Art of Seeing, in 1952, Bennett Cerf was present when Huxley spoke at a Hollywood banquet, wearing no glasses and apparently reading his paper from the lectern without difficulty: "Then suddenly he faltered—and the disturbing truth became obvious. He wasn't reading his address at all. He had learned it by heart. To refresh his memory he brought the paper closer and closer to his eyes. When it was only an inch or so away he still couldn't read it, and had to fish for a magnifying glass in his pocket to make the typing visible to him. It was an agonising moment."Brazilian author João Ubaldo Ribeiro, who as a young journalist spent several evenings in the Huxleys' company in the late 1950s, wrote that Huxley had said to him, with a wry smile: "I can hardly see at all. And I don't give a damn, really." Ribeiro then proceeds to confirm Bennett Cerf's experience, as described above. On the other hand, Huxley's second wife, Laura Archera, would later emphasise in her biographical account, This Timeless Moment: "One of the great achievements of his life: that of having regained his sight." After revealing a letter she wrote to the Los Angeles Times disclaiming the label of Huxley as a "poor fellow who can hardly see" by Walter C. Alvarez, she tempered this: "Although I feel it was an injustice to treat Aldous as though he were blind, it is true there were many indications of his impaired vision. For instance, although Aldous did not wear glasses, he would quite often use a magnifying lens." Laura Huxley proceeded to elaborate a few nuances of inconsistency peculiar to Huxley's vision. Her account, in this respect, is discernibly congruent with the following sample of Huxley's own words from The Art of Seeing: "The most characteristic fact about the functioning of the total organism, or any part of the organism, is that it is not constant, but highly variable." Nevertheless, the topic of Huxley's eyesight continues to endure similar, significant controversy, regardless of how trivial a subject matter it might initially appear.American popular science author Steven Johnson, in his book Mind Wide Open, quotes Huxley about his difficulties with visual encoding: "I am and, for as long as I can remember, I have always been a poor visualizer. Words, even the pregnant words of poets, do not evoke pictures in my mind. No hypnagogic visions greet me on the verge of sleep. When I recall something, the memory does not present itself to me as a vividly seen event or object. By an effort of the will, I can evoke a not very vivid image of what happened yesterday afternoon ...". == Personal life == Huxley married Maria Nys (10 September 1899 – 12 February 1955), a Belgian he met at Garsington, Oxfordshire, in 1919. They had one child, Matthew Huxley (19 April 1920 – 10 February 2005), who had a career as an author, anthropologist, and prominent epidemiologist. In 1955, Maria Huxley died of cancer.In 1956 Huxley married Laura Archera (1911–2007), also an author as well as a violinist and psychotherapist. She wrote This Timeless Moment, a biography of Huxley. She told the story of their marriage through Mary Ann Braubach's 2010 documentary, Huxley on Huxley.In 1960 Aldous Huxley was diagnosed with laryngeal cancer and, in the years that followed, with his health deteriorating, he wrote the Utopian novel Island, and gave lectures on "Human Potentialities" both at the University of California's San Francisco Medical Center and at the Esalen Institute. These lectures were fundamental to the beginning of the Human Potential Movement.Huxley was a close friend of Jiddu Krishnamurti and Rosalind Rajagopal and was involved in the creation of the Happy Valley School, now Besant Hill School of Happy Valley, in Ojai, California. The most substantial collection of Huxley's few remaining papers, following the destruction of most in a fire, is at the Library of the University of California, Los Angeles. Some are also at the Stanford University Libraries.On 9 April 1962, Huxley was informed he was elected Companion of Literature by the Royal Society of Literature, the senior literary organisation in Britain, and he accepted the title via letter on 28 April 1962. The correspondence between Huxley and the society are kept at the Cambridge University Library. The society invited Huxley to appear at a banquet and give a lecture at Somerset House, London in June 1963. Huxley wrote a draft of the speech he intended to give at the society; however, his deteriorating health meant he was not able to attend. == Death == On his deathbed, unable to speak owing to advanced laryngeal cancer, Huxley made a written request to his wife Laura for "LSD, 100 µg, intramuscular." According to her account of his death in This Timeless Moment, she obliged with an injection at 11:20 a.m. and a second dose an hour later; Huxley died aged 69, at 5:20 p.m. (Los Angeles time), on 22 November 1963.Media coverage of Huxley's death—as with that of the author C. S. Lewis–was overshadowed by the assassination of U.S. president John F. Kennedy on the same day. This coincidence served as the basis for Peter Kreeft's book Between Heaven and Hell: A Dialog Somewhere Beyond Death with John F. Kennedy, C. S. Lewis, & Aldous Huxley, which imagines a conversation among the three men taking place in Purgatory following their deaths.Huxley's memorial service took place in London in December 1963; it was led by his older brother Julian, and on 27 October 1971 his ashes were interred in the family grave at the Watts Cemetery, home of the Watts Mortuary Chapel in Compton, Guildford, Surrey, England.Huxley had been a long-time friend of Russian composer Igor Stravinsky, who later dedicated his last orchestral composition to Huxley. Stravinsky began Variations in Santa Fé, New Mexico, in July 1963, and completed the composition in Hollywood on 28 October 1964. It was first performed in Chicago on 17 April 1965, by the Chicago Symphony Orchestra conducted by Robert Craft. == Awards == 1939 James Tait Black Memorial Prize (for After Many a Summer Dies the Swan) 1959 American Academy of Arts and Letters Award of Merit (for Brave New World). 1962 Companion of Literature (Royal Society of Literature) == Film adaptations of Huxley's work == 1968 Point Counter Point (BBC miniseries by Simon Raven) 1971 The Devils (The Devils of Loudun adapted by Ken Russell) 1980 Brave New World (American TV adaptation) 1998 Brave New World (American TV adaptation) == Works == Novels1921 Crome Yellow 1923 Antic Hay 1925 Those Barren Leaves 1928 Point Counter Point 1932 Brave New World 1936 Eyeless in Gaza 1939 After Many a Summer 1944 Time Must Have a Stop 1948 Ape and Essence 1955 The Genius and the Goddess 1962 IslandShort story collections1920 Limbo 1922 Mortal Coils 1924 Little Mexican (US title: Young Archimedes) 1926 Two or Three Graces 1930 Brief Candles 1944 Collected Short Stories Jacob's Hands: A Fable (co-written with Christopher Isherwood; discovered 1997)Poetry collections1916 Oxford Poetry (magazine editor) 1916 The Burning Wheel 1917 Jonah 1918 The Defeat of Youth and Other Poems 1920 Leda 1925 Selected Poems 1929 Arabia Infelix and Other Poems 1931 The Cicadas and Other Poems 1971 Collected Poems Essay collections1923 On the Margin 1925 Along the Road 1926 Essays New and Old 1927 Proper Studies 1929 Do What You Will (Essays - full text) 1930 Vulgarity in Literature 1931 Music at Night 1932 Texts and Pretexts 1936 The Olive Tree and other essays (full text) 1937 Ends and Means 1940 Words and their Meanings 1945 The Perennial Philosophy 1946 Science, Liberty and Peace 1950 Themes and Variations 1954 The Doors of Perception 1956 Heaven and Hell 1956 Adonis and the Alphabet (US title: Tomorrow and Tomorrow and Tomorrow) 1958 Collected Essays 1958 Brave New World Revisited 1960 On Art and Artists 1963 Literature and Science 1977 Moksha: Writings on Psychedelics and the Visionary Experience 1931–63 1977 The Human Situation: Lectures at Santa Barbara, 1959ScreenplaysBrave New World Ape and Essence 1940 Pride and Prejudice (collaboration) 1943 Madame Curie (collaboration) 1944 Jane Eyre (collaboration with John Houseman) 1947 A Woman's Vengeance 1950 Prelude to Fame 1951 Original screenplay (rejected) for Disney's animated Alice in Wonderland  1971 Eyeless in Gaza (BBC mini-series in collaboration with Robin Chapman)Travel books1925 Along The Road: Notes and essays of a tourist 1926 Jesting Pilate: The Diary of a Journey 1934 Beyond the Mexique Bay: A Traveller's JourneyChildren's fiction1967 The Crows of PearblossomDrama1924 The Discovery (adapted from Francis Sheridan) 1931 The World of Light (full text) 1948 Mortal Coils – A Play (stage version of The Gioconda Smile) 1958 The Genius and the Goddess (stage version, co-written with Betty Wendel) 1967 The Ambassador of Captripedia 2000 Now More Than Ever (Lost play discovered by the Department of English Literature, University of Münster, Germany)Articles written for Vedanta and the West 1949 "Art and Religion 1950 "Foreword to an Essay on the Indian Philosophy of Peace" 1955 "Who Are We?" 1957 "The "Inanimate" is Alive" 1960 "Symbol and Immediate Experience"Audio recordings1955 Knowledge and Understanding  1955 Who Are We? Other1936 Pacifism and Philosophy 1937 An Encyclopedia of Pacifism (editor) (full text) 1941 Grey Eminence 1942 The Art of Seeing (exploration of Bates method of vision improvement) 1953 The Devils of Loudun 1962 The Politics of Ecology 2007 Selected Letters == References == == Sources == == Further reading == == External links == Bibliowiki has original media or text related to this article: Aldous Huxley (in the public domain in Canada) Works by Aldous Huxley at Project Gutenberg Works by or about Aldous Huxley at Internet Archive Works by Aldous Leonard Huxley at Faded Page (Canada) Works by Aldous Huxley at LibriVox (public domain audiobooks) Works by Aldous Huxley at Open Library Complete Works of Aldous Huxley Portraits at the National Portrait Gallery Aldous Huxley on IMDb Raymond Fraser, George Wickes (Spring 1960).

### Instruction: retrieve labels for this: Algae (; singular alga ) is an informal term for a large, diverse group of photosynthetic organisms that are not necessarily closely related, and is thus polyphyletic. Included organisms range from unicellular microalgae genera, such as Chlorella and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to 50 m in length. Most are aquatic and autotrophic and lack many of the distinct cell and tissue types, such as stomata, xylem, and phloem, which are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the Charophyta, a division of green algae which includes, for example, Spirogyra and the stoneworts. No definition of algae is generally accepted. One definition is that algae "have chlorophyll as their primary photosynthetic pigment and lack a sterile covering of cells around their reproductive cells". Some authors exclude all prokaryotes and thus do not consider cyanobacteria (blue-green algae) as algae.Algae constitute a polyphyletic group since they do not include a common ancestor, and although their plastids seem to have a single origin, from cyanobacteria, they were acquired in different ways. Green algae are examples of algae that have primary chloroplasts derived from endosymbiotic cyanobacteria. Diatoms and brown algae are examples of algae with secondary chloroplasts derived from an endosymbiotic red alga.Algae exhibit a wide range of reproductive strategies, from simple asexual cell division to complex forms of sexual reproduction.Algae lack the various structures that characterize land plants, such as the phyllids (leaf-like structures) of bryophytes, rhizoids in nonvascular plants, and the roots, leaves, and other organs found in tracheophytes (vascular plants). Most are phototrophic, although some are mixotrophic, deriving energy both from photosynthesis and uptake of organic carbon either by osmotrophy, myzotrophy, or phagotrophy. Some unicellular species of green algae, many golden algae, euglenids, dinoflagellates, and other algae have become heterotrophs (also called colorless or apochlorotic algae), sometimes parasitic, relying entirely on external energy sources and have limited or no photosynthetic apparatus. Some other heterotrophic organisms, such as the apicomplexans, are also derived from cells whose ancestors possessed plastids, but are not traditionally considered as algae. Algae have photosynthetic machinery ultimately derived from cyanobacteria that produce oxygen as a by-product of photosynthesis, unlike other photosynthetic bacteria such as purple and green sulfur bacteria. Fossilized filamentous algae from the Vindhya basin have been dated back to 1.6 to 1.7 billion years ago. == Etymology and study == The singular alga is the Latin word for "seaweed" and retains that meaning in English. The etymology is obscure. Although some speculate that it is related to Latin algēre, "be cold", no reason is known to associate seaweed with temperature. A more likely source is alliga, "binding, entwining".The Ancient Greek word for seaweed was φῦκος (phŷcos), which could mean either the seaweed (probably red algae) or a red dye derived from it. The Latinization, fūcus, meant primarily the cosmetic rouge. The etymology is uncertain, but a strong candidate has long been some word related to the Biblical פוך (pūk), "paint" (if not that word itself), a cosmetic eye-shadow used by the ancient Egyptians and other inhabitants of the eastern Mediterranean. It could be any color: black, red, green, or blue.Accordingly, the modern study of marine and freshwater algae is called either phycology or algology, depending on whether the Greek or Latin root is used. The name Fucus appears in a number of taxa. == Classification == The algae contain chloroplasts that are similar in structure to cyanobacteria. Chloroplasts contain circular DNA like that in cyanobacteria and are interpreted as representing reduced endosymbiotic cyanobacteria. However, the exact origin of the chloroplasts is different among separate lineages of algae, reflecting their acquisition during different endosymbiotic events. The table below describes the composition of the three major groups of algae. Their lineage relationships are shown in the figure in the upper right. Many of these groups contain some members that are no longer photosynthetic. Some retain plastids, but not chloroplasts, while others have lost plastids entirely. Phylogeny based on plastid not nucleocytoplasmic genealogy: Linnaeus, in Species Plantarum (1753), the starting point for modern botanical nomenclature, recognized 14 genera of algae, of which only four are currently considered among algae. In Systema Naturae, Linnaeus described the genera Volvox and Corallina, and a species of Acetabularia (as Madrepora), among the animals. In 1768, Samuel Gottlieb Gmelin (1744–1774) published the Historia Fucorum, the first work dedicated to marine algae and the first book on marine biology to use the then new binomial nomenclature of Linnaeus. It included elaborate illustrations of seaweed and marine algae on folded leaves.W.H.Harvey (1811—1866) and Lamouroux (1813) were the first to divide macroscopic algae into four divisions based on their pigmentation. This is the first use of a biochemical criterion in plant systematics. Harvey's four divisions are: red algae (Rhodospermae), brown algae (Melanospermae), green algae (Chlorospermae), and Diatomaceae.At this time, microscopic algae were discovered and reported by a different group of workers (e.g., O. F. Müller and Ehrenberg) studying the Infusoria (microscopic organisms). Unlike macroalgae, which were clearly viewed as plants, microalgae were frequently considered animals because they are often motile. Even the nonmotile (coccoid) microalgae were sometimes merely seen as stages of the lifecycle of plants, macroalgae, or animals.Although used as a taxonomic category in some pre-Darwinian classifications, e.g., Linnaeus (1753), de Jussieu (1789), Horaninow (1843), Agassiz (1859), Wilson & Cassin (1864), in further classifications, the "algae" are seen as an artificial, polyphyletic group. Throughout the 20th century, most classifications treated the following groups as divisions or classes of algae: cyanophytes, rhodophytes, chrysophytes, xanthophytes, bacillariophytes, phaeophytes, pyrrhophytes (cryptophytes and dinophytes), euglenophytes, and chlorophytes. Later, many new groups were discovered (e.g., Bolidophyceae), and others were splintered from older groups: charophytes and glaucophytes (from chlorophytes), many heterokontophytes (e.g., synurophytes from chrysophytes, or eustigmatophytes from xanthophytes), haptophytes (from chrysophytes), and chlorarachniophytes (from xanthophytes). With the abandonment of plant-animal dichotomous classification, most groups of algae (sometimes all) were included in Protista, later also abandoned in favour of Eukaryota. However, as a legacy of the older plant life scheme, some groups that were also treated as protozoans in the past still have duplicated classifications (see ambiregnal protists). Some parasitic algae (e.g., the green algae Prototheca and Helicosporidium, parasites of metazoans, or Cephaleuros, parasites of plants) were originally classified as fungi, sporozoans, or protistans of incertae sedis, while others (e.g., the green algae Phyllosiphon and Rhodochytrium, parasites of plants, or the red algae Pterocladiophila and Gelidiocolax mammillatus, parasites of other red algae, or the dinoflagellates Oodinium, parasites of fish) had their relationship with algae conjectured early. In other cases, some groups were originally characterized as parasitic algae (e.g., Chlorochytrium), but later were seen as endophytic algae. Some filamentous bacteria (e.g., Beggiatoa) were originally seen as algae. Furthermore, groups like the apicomplexans are also parasites derived from ancestors that possessed plastids, but are not included in any group traditionally seen as algae. == Relationship to land plants == The first land plants probably evolved from shallow freshwater charophyte algae much like Chara almost 500 million years ago. These probably had an isomorphic alternation of generations and were probably filamentous. Fossils of isolated land plant spores suggest land plants may have been around as long as 475 million years ago. == Morphology == A range of algal morphologies is exhibited, and convergence of features in unrelated groups is common. The only groups to exhibit three-dimensional multicellular thalli are the reds and browns, and some chlorophytes. Apical growth is constrained to subsets of these groups: the florideophyte reds, various browns, and the charophytes. The form of charophytes is quite different from those of reds and browns, because they have distinct nodes, separated by internode 'stems'; whorls of branches reminiscent of the horsetails occur at the nodes. Conceptacles are another polyphyletic trait; they appear in the coralline algae and the Hildenbrandiales, as well as the browns.Most of the simpler algae are unicellular flagellates or amoeboids, but colonial and nonmotile forms have developed independently among several of the groups. Some of the more common organizational levels, more than one of which may occur in the lifecycle of a species, are Colonial: small, regular groups of motile cells Capsoid: individual non-motile cells embedded in mucilage Coccoid: individual non-motile cells with cell walls Palmelloid: nonmotile cells embedded in mucilage Filamentous: a string of nonmotile cells connected together, sometimes branching Parenchymatous: cells forming a thallus with partial differentiation of tissuesIn three lines, even higher levels of organization have been reached, with full tissue differentiation. These are the brown algae,—some of which may reach 50 m in length (kelps)—the red algae, and the green algae. The most complex forms are found among the charophyte algae (see Charales and Charophyta), in a lineage that eventually led to the higher land plants. The innovation that defines these nonalgal plants is the presence of female reproductive organs with protective cell layers that protect the zygote and developing embryo. Hence, the land plants are referred to as the Embryophytes. == Physiology == Many algae, particularly members of the Characeae, have served as model experimental organisms to understand the mechanisms of the water permeability of membranes, osmoregulation, turgor regulation, salt tolerance, cytoplasmic streaming, and the generation of action potentials. Phytohormones are found not only in higher plants, but in algae, too. == Symbiotic algae == Some species of algae form symbiotic relationships with other organisms. In these symbioses, the algae supply photosynthates (organic substances) to the host organism providing protection to the algal cells. The host organism derives some or all of its energy requirements from the algae. Examples are: === Lichens === Lichens are defined by the International Association for Lichenology to be "an association of a fungus and a photosynthetic symbiont resulting in a stable vegetative body having a specific structure." The fungi, or mycobionts, are mainly from the Ascomycota with a few from the Basidiomycota. In nature they do not occur separate from lichens. It is unknown when they began to associate. One mycobiont associates with the same phycobiont species, rarely two, from the green algae, except that alternatively, the mycobiont may associate with a species of cyanobacteria (hence "photobiont" is the more accurate term). A photobiont may be associated with many different mycobionts or may live independently; accordingly, lichens are named and classified as fungal species. The association is termed a morphogenesis because the lichen has a form and capabilities not possessed by the symbiont species alone (they can be experimentally isolated). The photobiont possibly triggers otherwise latent genes in the mycobiont.Trentepohlia is an example of a common green alga genus worldwide that can grow on its own or be lichenised. Lichen thus share some of the habitat and often similar appearance with specialized species of algae (aerophytes) growing on exposed surfaces such as tree trunks and rocks and sometimes discoloring them. === Coral reefs === Coral reefs are accumulated from the calcareous exoskeletons of marine invertebrates of the order Scleractinia (stony corals). These animals metabolize sugar and oxygen to obtain energy for their cell-building processes, including secretion of the exoskeleton, with water and carbon dioxide as byproducts. Dinoflagellates (algal protists) are often endosymbionts in the cells of the coral-forming marine invertebrates, where they accelerate host-cell metabolism by generating sugar and oxygen immediately available through photosynthesis using incident light and the carbon dioxide produced by the host. Reef-building stony corals (hermatypic corals) require endosymbiotic algae from the genus Symbiodinium to be in a healthy condition. The loss of Symbiodinium from the host is known as coral bleaching, a condition which leads to the deterioration of a reef. === Sea sponges === Endosymbiontic green algae live close to the surface of some sponges, for example, breadcrumb sponges (Halichondria panicea). The alga is thus protected from predators; the sponge is provided with oxygen and sugars which can account for 50 to 80% of sponge growth in some species. == Lifecycle == Rhodophyta, Chlorophyta, and Heterokontophyta, the three main algal divisions, have lifecycles which show considerable variation and complexity. In general, an asexual phase exists where the seaweed's cells are diploid, a sexual phase where the cells are haploid, followed by fusion of the male and female gametes. Asexual reproduction permits efficient population increases, but less variation is possible. Commonly, in sexual reproduction of unicellular and colonial algae, two specialized, sexually compatible, haploid gametes make physical contact and fuse to form a zygote. To ensure a successful mating, the development and release of gametes is highly synchronized and regulated; pheromones may play a key role in these processes. Sexual reproduction allows for more variation and provides the benefit of efficient recombinational repair of DNA damages during meiosis, a key stage of the sexual cycle. However, sexual reproduction is more costly than asexual reproduction. Meiosis has been shown to occur in many different species of algae. == Numbers == The Algal Collection of the US National Herbarium (located in the National Museum of Natural History) consists of approximately 320,500 dried specimens, which, although not exhaustive (no exhaustive collection exists), gives an idea of the order of magnitude of the number of algal species (that number remains unknown). Estimates vary widely. For example, according to one standard textbook, in the British Isles the UK Biodiversity Steering Group Report estimated there to be 20,000 algal species in the UK. Another checklist reports only about 5,000 species. Regarding the difference of about 15,000 species, the text concludes: "It will require many detailed field surveys before it is possible to provide a reliable estimate of the total number of species ..." Regional and group estimates have been made, as well: 5,000–5,500 species of red algae worldwide "some 1,300 in Australian Seas" 400 seaweed species for the western coastline of South Africa, and 212 species from the coast of KwaZulu-Natal. Some of these are duplicates, as the range extends across both coasts, and the total recorded is probably about 500 species. Most of these are listed in List of seaweeds of South Africa. These exclude phytoplankton and crustose corallines. 669 marine species from California (US) 642 in the check-list of Britain and Irelandand so on, but lacking any scientific basis or reliable sources, these numbers have no more credibility than the British ones mentioned above. Most estimates also omit microscopic algae, such as phytoplankton. The most recent estimate suggests 72,500 algal species worldwide. == Distribution == The distribution of algal species has been fairly well studied since the founding of phytogeography in the mid-19th century. Algae spread mainly by the dispersal of spores analogously to the dispersal of Plantae by seeds and spores. This dispersal can be accomplished by air, water, or other organisms. Due to this, spores can be found in a variety of environments: fresh and marine waters, air, soil, and in or on other organisms. Whether a spore is to grow into an organism depends on the combination of the species and the environmental conditions where the spore lands. The spores of freshwater algae are dispersed mainly by running water and wind, as well as by living carriers. However, not all bodies of water can carry all species of algae, as the chemical composition of certain water bodies limits the algae that can survive within them. Marine spores are often spread by ocean currents. Ocean water presents many vastly different habitats based on temperature and nutrient availability, resulting in phytogeographic zones, regions, and provinces.To some degree, the distribution of algae is subject to floristic discontinuities caused by geographical features, such as Antarctica, long distances of ocean or general land masses. It is, therefore, possible to identify species occurring by locality, such as "Pacific algae" or "North Sea algae". When they occur out of their localities, hypothesizing a transport mechanism is usually possible, such as the hulls of ships. For example, Ulva reticulata and U. fasciata travelled from the mainland to Hawaii in this manner. Mapping is possible for select species only: "there are many valid examples of confined distribution patterns." For example, Clathromorphum is an arctic genus and is not mapped far south of there. However, scientists regard the overall data as insufficient due to the "difficulties of undertaking such studies." == Ecology == Algae are prominent in bodies of water, common in terrestrial environments, and are found in unusual environments, such as on snow and ice. Seaweeds grow mostly in shallow marine waters, under 100 m (330 ft) deep; however, some such as Navicula pennata have been recorded to a depth of 360 m (1,180 ft).The various sorts of algae play significant roles in aquatic ecology. Microscopic forms that live suspended in the water column (phytoplankton) provide the food base for most marine food chains. In very high densities (algal blooms), these algae may discolor the water and outcompete, poison, or asphyxiate other life forms. Algae can be used as indicator organisms to monitor pollution in various aquatic systems. In many cases, algal metabolism is sensitive to various pollutants. Due to this, the species composition of algal populations may shift in the presence of chemical pollutants. To detect these changes, algae can be sampled from the environment and maintained in laboratories with relative ease.On the basis of their habitat, algae can be categorized as: aquatic (planktonic, benthic, marine, freshwater, lentic, lotic), terrestrial, aerial (subareial), lithophytic, halophytic (or euryhaline), psammon, thermophilic, cryophilic, epibiont (epiphytic, epizoic), endosymbiont (endophytic, endozoic), parasitic, calcifilic or lichenic (phycobiont). == Cultural associations == In classical Chinese, the word 藻 is used both for "algae" and (in the modest tradition of the imperial scholars) for "literary talent". The third island in Kunming Lake beside the Summer Palace in Beijing is known as the Zaojian Tang Dao, which thus simultaneously means "Island of the Algae-Viewing Hall" and "Island of the Hall for Reflecting on Literary Talent". == Uses == === Agar === Agar, a gelatinous substance derived from red algae, has a number of commercial uses. It is a good medium on which to grow bacteria and fungi, as most microorganisms cannot digest agar. === Alginates === Alginic acid, or alginate, is extracted from brown algae. Its uses range from gelling agents in food, to medical dressings. Alginic acid also has been used in the field of biotechnology as a biocompatible medium for cell encapsulation and cell immobilization. Molecular cuisine is also a user of the substance for its gelling properties, by which it becomes a delivery vehicle for flavours. Between 100,000 and 170,000 wet tons of Macrocystis are harvested annually in New Mexico for alginate extraction and abalone feed. === Energy source === To be competitive and independent from fluctuating support from (local) policy on the long run, biofuels should equal or beat the cost level of fossil fuels. Here, algae-based fuels hold great promise, directly related to the potential to produce more biomass per unit area in a year than any other form of biomass. The break-even point for algae-based biofuels is estimated to occur by 2025. === Fertilizer === For centuries, seaweed has been used as a fertilizer; George Owen of Henllys writing in the 16th century referring to drift weed in South Wales:This kind of ore they often gather and lay on great heapes, where it heteth and rotteth, and will have a strong and loathsome smell; when being so rotten they cast on the land, as they do their muck, and thereof springeth good corn, especially barley ... After spring-tydes or great rigs of the sea, they fetch it in sacks on horse backes, and carie the same three, four, or five miles, and cast it on the lande, which doth very much better the ground for corn and grass. Today, algae are used by humans in many ways; for example, as fertilizers, soil conditioners, and livestock feed. Aquatic and microscopic species are cultured in clear tanks or ponds and are either harvested or used to treat effluents pumped through the ponds. Algaculture on a large scale is an important type of aquaculture in some places. Maerl is commonly used as a soil conditioner. === Nutrition === Naturally growing seaweeds are an important source of food, especially in Asia. They provide many vitamins including: A, B1, B2, B6, niacin, and C, and are rich in iodine, potassium, iron, magnesium, and calcium. In addition, commercially cultivated microalgae, including both algae and cyanobacteria, are marketed as nutritional supplements, such as spirulina, Chlorella and the vitamin-C supplement from Dunaliella, high in beta-carotene. Algae are national foods of many nations: China consumes more than 70 species, including fat choy, a cyanobacterium considered a vegetable; Japan, over 20 species; Ireland, dulse; Chile, cochayuyo. Laver is used to make "laver bread" in Wales, where it is known as bara lawr; in Korea, gim; in Japan, nori and aonori. It is also used along the west coast of North America from California to British Columbia, in Hawaii and by the Māori of New Zealand. Sea lettuce and badderlocks are salad ingredients in Scotland, Ireland, Greenland, and Iceland. Algae is being considered a potential solution for world hunger problem.The oils from some algae have high levels of unsaturated fatty acids. For example, Parietochloris incisa is very high in arachidonic acid, where it reaches up to 47% of the triglyceride pool. Some varieties of algae favored by vegetarianism and veganism contain the long-chain, essential omega-3 fatty acids, docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). Fish oil contains the omega-3 fatty acids, but the original source is algae (microalgae in particular), which are eaten by marine life such as copepods and are passed up the food chain. Algae have emerged in recent years as a popular source of omega-3 fatty acids for vegetarians who cannot get long-chain EPA and DHA from other vegetarian sources such as flaxseed oil, which only contains the short-chain alpha-linolenic acid (ALA). === Pollution control === Sewage can be treated with algae, reducing the use of large amounts of toxic chemicals that would otherwise be needed. Algae can be used to capture fertilizers in runoff from farms. When subsequently harvested, the enriched algae can be used as fertilizer. Aquaria and ponds can be filtered using algae, which absorb nutrients from the water in a device called an algae scrubber, also known as an algae turf scrubber.Agricultural Research Service scientists found that 60–90% of nitrogen runoff and 70–100% of phosphorus runoff can be captured from manure effluents using a horizontal algae scrubber, also called an algal turf scrubber (ATS). Scientists developed the ATS, which consists of shallow, 100-foot raceways of nylon netting where algae colonies can form, and studied its efficacy for three years. They found that algae can readily be used to reduce the nutrient runoff from agricultural fields and increase the quality of water flowing into rivers, streams, and oceans. Researchers collected and dried the nutrient-rich algae from the ATS and studied its potential as an organic fertilizer. They found that cucumber and corn seedlings grew just as well using ATS organic fertilizer as they did with commercial fertilizers. Algae scrubbers, using bubbling upflow or vertical waterfall versions, are now also being used to filter aquaria and ponds. === Polymers === Various polymers can be created from algae, which can be especially useful in the creation of bioplastics. These include hybrid plastics, cellulose based plastics, poly-lactic acid, and bio-polyethylene. Several companies have begun to produce algae polymers commercially, including for use in flip-flops and in surf boards. === Bioremediation === The alga Stichococcus bacillaris has been seen to colonize silicone resins used at archaeological sites; biodegrading the synthetic substance. === Pigments === The natural pigments (carotenoids and chlorophylls) produced by algae can be used as alternatives to chemical dyes and coloring agents. The presence of some individual algal pigments, together with specific pigment concentration ratios, are taxon-specific: analysis of their concentrations with various analytical methods, particularly high-performance liquid chromatography, can therefore offer deep insight into the taxonomic composition and relative abundance of natural algae populations in sea water samples. === Stabilizing substances === Carrageenan, from the red alga Chondrus crispus, is used as a stabilizer in milk products. == Additional images == == See also == AlgaeBase AlgaePARC Toxoid - anatoxin Eutrophication Marimo algae Iron fertilization Microbiofuels Microphyte Photobioreactor Plant == References == == Bibliography == == External links == Guiry, Michael and Wendy.

### Instruction: retrieve labels for this: Analysis of variance (ANOVA) is a collection of statistical models and their associated estimation procedures (such as the "variation" among and between groups) used to analyze the differences among group means in a sample. ANOVA was developed by statistician and evolutionary biologist Ronald Fisher. In the ANOVA setting, the observed variance in a particular variable is partitioned into components attributable to different sources of variation. In its simplest form, ANOVA provides a statistical test of whether the population means of several groups are equal, and therefore generalizes the t-test to more than two groups. ANOVA is useful for comparing (testing) three or more group means for statistical significance. It is conceptually similar to multiple two-sample t-tests, but is more conservative (results in less type I error) and is therefore suited to a wide range of practical problems. == History == While the analysis of variance reached fruition in the 20th century, antecedents extend centuries into the past according to Stigler. These include hypothesis testing, the partitioning of sums of squares, experimental techniques and the additive model. Laplace was performing hypothesis testing in the 1770s. The development of least-squares methods by Laplace and Gauss circa 1800 provided an improved method of combining observations (over the existing practices then used in astronomy and geodesy). It also initiated much study of the contributions to sums of squares. Laplace knew how to estimate a variance from a residual (rather than a total) sum of squares. By 1827 Laplace was using least squares methods to address ANOVA problems regarding measurements of atmospheric tides. Before 1800 astronomers had isolated observational errors resulting from reaction times (the "personal equation") and had developed methods of reducing the errors. The experimental methods used in the study of the personal equation were later accepted by the emerging field of psychology which developed strong (full factorial) experimental methods to which randomization and blinding were soon added. An eloquent non-mathematical explanation of the additive effects model was available in 1885.Ronald Fisher introduced the term variance and proposed its formal analysis in a 1918 article The Correlation Between Relatives on the Supposition of Mendelian Inheritance. His first application of the analysis of variance was published in 1921. Analysis of variance became widely known after being included in Fisher's 1925 book Statistical Methods for Research Workers. Randomization models were developed by several researchers. The first was published in Polish by Jerzy Neyman in 1923.One of the attributes of ANOVA that ensured its early popularity was computational elegance. The structure of the additive model allows solution for the additive coefficients by simple algebra rather than by matrix calculations. In the era of mechanical calculators this simplicity was critical. The determination of statistical significance also required access to tables of the F function which were supplied by early statistics texts. == Motivating example == The analysis of variance can be used as an exploratory tool to explain observations. A dog show provides an example. A dog show is not a random sampling of the breed: it is typically limited to dogs that are adult, pure-bred, and exemplary. A histogram of dog weights from a show might plausibly be rather complex, like the yellow-orange distribution shown in the illustrations. Suppose we wanted to predict the weight of a dog based on a certain set of characteristics of each dog. One way to do that is to explain the distribution of weights by dividing the dog population into groups based on those characteristics. A successful grouping will split dogs such that (a) each group has a low variance of dog weights (meaning the group is relatively homogeneous) and (b) the mean of each group is distinct (if two groups have the same mean, then it isn't reasonable to conclude that the groups are, in fact, separate in any meaningful way). In the illustrations to the right, groups are identified as X1, X2, etc. In the first illustration, the dogs are divided according to the product (interaction) of two binary groupings: young vs old, and short-haired vs long-haired (e.g., group 1 is young, short-haired dogs, group 2 is young, long-haired dogs, etc.). Since the distributions of dog weight within each of the groups (shown in blue) has a relatively large variance, and since the means are very similar across groups, grouping dogs by these characteristics does not produce an effective way to explain the variation in dog weights: knowing which group a dog is in doesn't allow us to predict its weight much better than simply knowing the dog is in a dog show. Thus, this grouping fails to explain the variation in the overall distribution (yellow-orange). An attempt to explain the weight distribution by grouping dogs as pet vs working breed and less athletic vs more athletic would probably be somewhat more successful (fair fit). The heaviest show dogs are likely to be big strong working breeds, while breeds kept as pets tend to be smaller and thus lighter. As shown by the second illustration, the distributions have variances that are considerably smaller than in the first case, and the means are more distinguishable. However, the significant overlap of distributions, for example, means that we cannot distinguish X1 and X2 reliably. Grouping dogs according to a coin flip might produce distributions that look similar. An attempt to explain weight by breed is likely to produce a very good fit. All Chihuahuas are light and all St Bernards are heavy. The difference in weights between Setters and Pointers does not justify separate breeds. The analysis of variance provides the formal tools to justify these intuitive judgments. A common use of the method is the analysis of experimental data or the development of models. The method has some advantages over correlation: not all of the data must be numeric and one result of the method is a judgment in the confidence in an explanatory relationship. == Background and terminology == ANOVA is a form of statistical hypothesis testing heavily used in the analysis of experimental data. A test result (calculated from the null hypothesis and the sample) is called statistically significant if it is deemed unlikely to have occurred by chance, assuming the truth of the null hypothesis. A statistically significant result, when a probability (p-value) is less than a pre-specified threshold (significance level), justifies the rejection of the null hypothesis, but only if the a priori probability of the null hypothesis is not high. In the typical application of ANOVA, the null hypothesis is that all groups are random samples from the same population. For example, when studying the effect of different treatments on similar samples of patients, the null hypothesis would be that all treatments have the same effect (perhaps none). Rejecting the null hypothesis is taken to mean that the differences in observed effects between treatment groups are unlikely to be due to random chance. By construction, hypothesis testing limits the rate of Type I errors (false positives) to a significance level. Experimenters also wish to limit Type II errors (false negatives). The rate of Type II errors depends largely on sample size (the rate is larger for smaller samples), significance level (when the standard of proof is high, the chances of overlooking a discovery are also high) and effect size (a smaller effect size is more prone to Type II error). The terminology of ANOVA is largely from the statistical design of experiments. The experimenter adjusts factors and measures responses in an attempt to determine an effect. Factors are assigned to experimental units by a combination of randomization and blocking to ensure the validity of the results. Blinding keeps the weighing impartial. Responses show a variability that is partially the result of the effect and is partially random error. ANOVA is the synthesis of several ideas and it is used for multiple purposes. As a consequence, it is difficult to define concisely or precisely. "Classical" ANOVA for balanced data does three things at once: In short, ANOVA is a statistical tool used in several ways to develop and confirm an explanation for the observed data. Additionally: As a result: ANOVA "has long enjoyed the status of being the most used (some would say abused) statistical technique in psychological research." ANOVA "is probably the most useful technique in the field of statistical inference."ANOVA is difficult to teach, particularly for complex experiments, with split-plot designs being notorious. In some cases the proper application of the method is best determined by problem pattern recognition followed by the consultation of a classic authoritative test. === Design-of-experiments terms === (Condensed from the NIST Engineering Statistics handbook: Section 5.7. A Glossary of DOE Terminology.) Balanced design An experimental design where all cells (i.e. treatment combinations) have the same number of observations. Blocking A schedule for conducting treatment combinations in an experimental study such that any effects on the experimental results due to a known change in raw materials, operators, machines, etc., become concentrated in the levels of the blocking variable. The reason for blocking is to isolate a systematic effect and prevent it from obscuring the main effects. Blocking is achieved by restricting randomization. Design A set of experimental runs which allows the fit of a particular model and the estimate of effects. DOE Design of experiments. An approach to problem solving involving collection of data that will support valid, defensible, and supportable conclusions. Effect How changing the settings of a factor changes the response. The effect of a single factor is also called a main effect. Error Unexplained variation in a collection of observations. DOE's typically require understanding of both random error and lack of fit error. Experimental unit The entity to which a specific treatment combination is applied. Factors Process inputs that an investigator manipulates to cause a change in the output. Lack-of-fit error Error that occurs when the analysis omits one or more important terms or factors from the process model. Including replication in a DOE allows separation of experimental error into its components: lack of fit and random (pure) error. Model Mathematical relationship which relates changes in a given response to changes in one or more factors. Random error Error that occurs due to natural variation in the process. Random error is typically assumed to be normally distributed with zero mean and a constant variance. Random error is also called experimental error. Randomization A schedule for allocating treatment material and for conducting treatment combinations in a DOE such that the conditions in one run neither depend on the conditions of the previous run nor predict the conditions in the subsequent runs. Replication Performing the same treatment combination more than once. Including replication allows an estimate of the random error independent of any lack of fit error. Responses The output(s) of a process. Sometimes called dependent variable(s). Treatment A treatment is a specific combination of factor levels whose effect is to be compared with other treatments. ==== Anova Table ==== SSE - Sum of Square due to Error SST - Sum of Square of Treatment MST - Mean sum of Square Treatment MSE - Mean Sum of Square df - Degrees of Freedom SSR - Sum of Square of Treatment in Rows (SST) SSC - Sum of Square between Column MSV - Mean Sum of Variance == Classes of models == There are three classes of models used in the analysis of variance, and these are outlined here. === Fixed-effects models === The fixed-effects model (class I) of analysis of variance applies to situations in which the experimenter applies one or more treatments to the subjects of the experiment to see whether the response variable values change. This allows the experimenter to estimate the ranges of response variable values that the treatment would generate in the population as a whole. === Random-effects models === Random effects model (class II) is used when the treatments are not fixed. This occurs when the various factor levels are sampled from a larger population. Because the levels themselves are random variables, some assumptions and the method of contrasting the treatments (a multi-variable generalization of simple differences) differ from the fixed-effects model. === Mixed-effects models === A mixed-effects model (class III) contains experimental factors of both fixed and random-effects types, with appropriately different interpretations and analysis for the two types. Example: Teaching experiments could be performed by a college or university department to find a good introductory textbook, with each text considered a treatment. The fixed-effects model would compare a list of candidate texts. The random-effects model would determine whether important differences exist among a list of randomly selected texts. The mixed-effects model would compare the (fixed) incumbent texts to randomly selected alternatives. Defining fixed and random effects has proven elusive, with competing definitions arguably leading toward a linguistic quagmire. == Assumptions == The analysis of variance has been studied from several approaches, the most common of which uses a linear model that relates the response to the treatments and blocks. Note that the model is linear in parameters but may be nonlinear across factor levels. Interpretation is easy when data is balanced across factors but much deeper understanding is needed for unbalanced data. === Textbook analysis using a normal distribution === The analysis of variance can be presented in terms of a linear model, which makes the following assumptions about the probability distribution of the responses: Independence of observations – this is an assumption of the model that simplifies the statistical analysis. Normality – the distributions of the residuals are normal. Equality (or "homogeneity") of variances, called homoscedasticity — the variance of data in groups should be the same.The separate assumptions of the textbook model imply that the errors are independently, identically, and normally distributed for fixed effects models, that is, that the errors ( ε {\displaystyle \varepsilon } ) are independent and ε ∼ N ( 0 , σ 2 ) . {\displaystyle \varepsilon \thicksim N(0,\sigma ^{2}).\,} === Randomization-based analysis === In a randomized controlled experiment, the treatments are randomly assigned to experimental units, following the experimental protocol. This randomization is objective and declared before the experiment is carried out. The objective random-assignment is used to test the significance of the null hypothesis, following the ideas of C. S. Peirce and Ronald Fisher. This design-based analysis was discussed and developed by Francis J. Anscombe at Rothamsted Experimental Station and by Oscar Kempthorne at Iowa State University. Kempthorne and his students make an assumption of unit treatment additivity, which is discussed in the books of Kempthorne and David R. Cox. ==== Unit-treatment additivity ==== In its simplest form, the assumption of unit-treatment additivity states that the observed response y i , j {\displaystyle y_{i,j}} from experimental unit i {\displaystyle i} when receiving treatment j {\displaystyle j} can be written as the sum of the unit's response y i {\displaystyle y_{i}} and the treatment-effect t j {\displaystyle t_{j}} , that is y i , j = y i + t j . {\displaystyle y_{i,j}=y_{i}+t_{j}.} The assumption of unit-treatment additivity implies that, for every treatment j {\displaystyle j} , the j {\displaystyle j} th treatment has exactly the same effect t j {\displaystyle t_{j}} on every experiment unit. The assumption of unit treatment additivity usually cannot be directly falsified, according to Cox and Kempthorne. However, many consequences of treatment-unit additivity can be falsified. For a randomized experiment, the assumption of unit-treatment additivity implies that the variance is constant for all treatments. Therefore, by contraposition, a necessary condition for unit-treatment additivity is that the variance is constant. The use of unit treatment additivity and randomization is similar to the design-based inference that is standard in finite-population survey sampling. ==== Derived linear model ==== Kempthorne uses the randomization-distribution and the assumption of unit treatment additivity to produce a derived linear model, very similar to the textbook model discussed previously. The test statistics of this derived linear model are closely approximated by the test statistics of an appropriate normal linear model, according to approximation theorems and simulation studies. However, there are differences. For example, the randomization-based analysis results in a small but (strictly) negative correlation between the observations. In the randomization-based analysis, there is no assumption of a normal distribution and certainly no assumption of independence. On the contrary, the observations are dependent! The randomization-based analysis has the disadvantage that its exposition involves tedious algebra and extensive time. Since the randomization-based analysis is complicated and is closely approximated by the approach using a normal linear model, most teachers emphasize the normal linear model approach. Few statisticians object to model-based analysis of balanced randomized experiments. ==== Statistical models for observational data ==== However, when applied to data from non-randomized experiments or observational studies, model-based analysis lacks the warrant of randomization. For observational data, the derivation of confidence intervals must use subjective models, as emphasized by Ronald Fisher and his followers. In practice, the estimates of treatment-effects from observational studies generally are often inconsistent. In practice, "statistical models" and observational data are useful for suggesting hypotheses that should be treated very cautiously by the public. === Summary of assumptions === The normal-model based ANOVA analysis assumes the independence, normality and homogeneity of the variances of the residuals. The randomization-based analysis assumes only the homogeneity of the variances of the residuals (as a consequence of unit-treatment additivity) and uses the randomization procedure of the experiment. Both these analyses require homoscedasticity, as an assumption for the normal-model analysis and as a consequence of randomization and additivity for the randomization-based analysis. However, studies of processes that change variances rather than means (called dispersion effects) have been successfully conducted using ANOVA. There are no necessary assumptions for ANOVA in its full generality, but the F-test used for ANOVA hypothesis testing has assumptions and practical limitations which are of continuing interest. Problems which do not satisfy the assumptions of ANOVA can often be transformed to satisfy the assumptions. The property of unit-treatment additivity is not invariant under a "change of scale", so statisticians often use transformations to achieve unit-treatment additivity. If the response variable is expected to follow a parametric family of probability distributions, then the statistician may specify (in the protocol for the experiment or observational study) that the responses be transformed to stabilize the variance. Also, a statistician may specify that logarithmic transforms be applied to the responses, which are believed to follow a multiplicative model. According to Cauchy's functional equation theorem, the logarithm is the only continuous transformation that transforms real multiplication to addition. == Characteristics == ANOVA is used in the analysis of comparative experiments, those in which only the difference in outcomes is of interest. The statistical significance of the experiment is determined by a ratio of two variances. This ratio is independent of several possible alterations to the experimental observations: Adding a constant to all observations does not alter significance. Multiplying all observations by a constant does not alter significance. So ANOVA statistical significance result is independent of constant bias and scaling errors as well as the units used in expressing observations. In the era of mechanical calculation it was common to subtract a constant from all observations (when equivalent to dropping leading digits) to simplify data entry. This is an example of data coding. == Logic == The calculations of ANOVA can be characterized as computing a number of means and variances, dividing two variances and comparing the ratio to a handbook value to determine statistical significance. Calculating a treatment effect is then trivial, "the effect of any treatment is estimated by taking the difference between the mean of the observations which receive the treatment and the general mean". === Partitioning of the sum of squares === ANOVA uses traditional standardized terminology. The definitional equation of sample variance is s 2 = 1 n − 1 ∑ ( y i − y ¯ ) 2 {\displaystyle s^{2}=\textstyle {\frac {1}{n-1}}\sum (y_{i}-{\bar {y}})^{2}} , where the divisor is called the degrees of freedom (DF), the summation is called the sum of squares (SS), the result is called the mean square (MS) and the squared terms are deviations from the sample mean. ANOVA estimates 3 sample variances: a total variance based on all the observation deviations from the grand mean, an error variance based on all the observation deviations from their appropriate treatment means, and a treatment variance. The treatment variance is based on the deviations of treatment means from the grand mean, the result being multiplied by the number of observations in each treatment to account for the difference between the variance of observations and the variance of means. The fundamental technique is a partitioning of the total sum of squares SS into components related to the effects used in the model. For example, the model for a simplified ANOVA with one type of treatment at different levels. S S Total = S S Error + S S Treatments {\displaystyle SS_{\text{Total}}=SS_{\text{Error}}+SS_{\text{Treatments}}} The number of degrees of freedom DF can be partitioned in a similar way: one of these components (that for error) specifies a chi-squared distribution which describes the associated sum of squares, while the same is true for "treatments" if there is no treatment effect. D F Total = D F Error + D F Treatments {\displaystyle DF_{\text{Total}}=DF_{\text{Error}}+DF_{\text{Treatments}}} See also Lack-of-fit sum of squares. === The F-test === The F-test is used for comparing the factors of the total deviation. For example, in one-way, or single-factor ANOVA, statistical significance is tested for by comparing the F test statistic F = variance between treatments variance within treatments {\displaystyle F={\frac {\text{variance between treatments}}{\text{variance within treatments}}}} F = M S Treatments M S Error = S S Treatments / ( I − 1 ) S S Error / ( n T − I ) {\displaystyle F={\frac {MS_{\text{Treatments}}}{MS_{\text{Error}}}}={{SS_{\text{Treatments}}/(I-1)} \over {SS_{\text{Error}}/(n_{T}-I)}}} where MS is mean square, I {\displaystyle I} = number of treatments and n T {\displaystyle n_{T}} = total number of cases to the F-distribution with I − 1 {\displaystyle I-1} , n T − I {\displaystyle n_{T}-I} degrees of freedom. Using the F-distribution is a natural candidate because the test statistic is the ratio of two scaled sums of squares each of which follows a scaled chi-squared distribution. The expected value of F is 1 + n σ Treatment 2 / σ Error 2 {\displaystyle 1+{n\sigma _{\text{Treatment}}^{2}}/{\sigma _{\text{Error}}^{2}}} (where n is the treatment sample size) which is 1 for no treatment effect. As values of F increase above 1, the evidence is increasingly inconsistent with the null hypothesis. Two apparent experimental methods of increasing F are increasing the sample size and reducing the error variance by tight experimental controls. There are two methods of concluding the ANOVA hypothesis test, both of which produce the same result: The textbook method is to compare the observed value of F with the critical value of F determined from tables. The critical value of F is a function of the degrees of freedom of the numerator and the denominator and the significance level (α). If F ≥ FCritical, the null hypothesis is rejected. The computer method calculates the probability (p-value) of a value of F greater than or equal to the observed value. The null hypothesis is rejected if this probability is less than or equal to the significance level (α).The ANOVA F-test is known to be nearly optimal in the sense of minimizing false negative errors for a fixed rate of false positive errors (i.e. maximizing power for a fixed significance level). For example, to test the hypothesis that various medical treatments have exactly the same effect, the F-test's p-values closely approximate the permutation test's p-values: The approximation is particularly close when the design is balanced. Such permutation tests characterize tests with maximum power against all alternative hypotheses, as observed by Rosenbaum. The ANOVA F–test (of the null-hypothesis that all treatments have exactly the same effect) is recommended as a practical test, because of its robustness against many alternative distributions. === Extended logic === ANOVA consists of separable parts; partitioning sources of variance and hypothesis testing can be used individually. ANOVA is used to support other statistical tools. Regression is first used to fit more complex models to data, then ANOVA is used to compare models with the objective of selecting simple(r) models that adequately describe the data. "Such models could be fit without any reference to ANOVA, but ANOVA tools could then be used to make some sense of the fitted models, and to test hypotheses about batches of coefficients." "[W]e think of the analysis of variance as a way of understanding and structuring multilevel models—not as an alternative to regression but as a tool for summarizing complex high-dimensional inferences ..." == For a single factor == The simplest experiment suitable for ANOVA analysis is the completely randomized experiment with a single factor. More complex experiments with a single factor involve constraints on randomization and include completely randomized blocks and Latin squares (and variants: Graeco-Latin squares, etc.). The more complex experiments share many of the complexities of multiple factors. A relatively complete discussion of the analysis (models, data summaries, ANOVA table) of the completely randomized experiment is available. == For multiple factors == ANOVA generalizes to the study of the effects of multiple factors. When the experiment includes observations at all combinations of levels of each factor, it is termed factorial. Factorial experiments are more efficient than a series of single factor experiments and the efficiency grows as the number of factors increases. Consequently, factorial designs are heavily used. The use of ANOVA to study the effects of multiple factors has a complication. In a 3-way ANOVA with factors x, y and z, the ANOVA model includes terms for the main effects (x, y, z) and terms for interactions (xy, xz, yz, xyz). All terms require hypothesis tests. The proliferation of interaction terms increases the risk that some hypothesis test will produce a false positive by chance. Fortunately, experience says that high order interactions are rare. The ability to detect interactions is a major advantage of multiple factor ANOVA. Testing one factor at a time hides interactions, but produces apparently inconsistent experimental results.Caution is advised when encountering interactions; Test interaction terms first and expand the analysis beyond ANOVA if interactions are found. Texts vary in their recommendations regarding the continuation of the ANOVA procedure after encountering an interaction. Interactions complicate the interpretation of experimental data. Neither the calculations of significance nor the estimated treatment effects can be taken at face value. "A significant interaction will often mask the significance of main effects." Graphical methods are recommended to enhance understanding. Regression is often useful. A lengthy discussion of interactions is available in Cox (1958). Some interactions can be removed (by transformations) while others cannot. A variety of techniques are used with multiple factor ANOVA to reduce expense. One technique used in factorial designs is to minimize replication (possibly no replication with support of analytical trickery) and to combine groups when effects are found to be statistically (or practically) insignificant. An experiment with many insignificant factors may collapse into one with a few factors supported by many replications. == Worked numeric examples == Several fully worked numerical examples are available. A simple case uses one-way (a single factor) analysis. A more complex case uses two-way (two-factor) analysis. == Associated analysis == Some analysis is required in support of the design of the experiment while other analysis is performed after changes in the factors are formally found to produce statistically significant changes in the responses. Because experimentation is iterative, the results of one experiment alter plans for following experiments. === Preparatory analysis === ==== The number of experimental units ==== In the design of an experiment, the number of experimental units is planned to satisfy the goals of the experiment. Experimentation is often sequential. Early experiments are often designed to provide mean-unbiased estimates of treatment effects and of experimental error. Later experiments are often designed to test a hypothesis that a treatment effect has an important magnitude; in this case, the number of experimental units is chosen so that the experiment is within budget and has adequate power, among other goals. Reporting sample size analysis is generally required in psychology. "Provide information on sample size and the process that led to sample size decisions." The analysis, which is written in the experimental protocol before the experiment is conducted, is examined in grant applications and administrative review boards. Besides the power analysis, there are less formal methods for selecting the number of experimental units. These include graphical methods based on limiting the probability of false negative errors, graphical methods based on an expected variation increase (above the residuals) and methods based on achieving a desired confident interval. ==== Power analysis ==== Power analysis is often applied in the context of ANOVA in order to assess the probability of successfully rejecting the null hypothesis if we assume a certain ANOVA design, effect size in the population, sample size and significance level. Power analysis can assist in study design by determining what sample size would be required in order to have a reasonable chance of rejecting the null hypothesis when the alternative hypothesis is true. ==== Effect size ==== Several standardized measures of effect have been proposed for ANOVA to summarize the strength of the association between a predictor(s) and the dependent variable or the overall standardized difference of the complete model. Standardized effect-size estimates facilitate comparison of findings across studies and disciplines. However, while standardized effect sizes are commonly used in much of the professional literature, a non-standardized measure of effect size that has immediately "meaningful" units may be preferable for reporting purposes. === Follow-up analysis === It is always appropriate to carefully consider outliers. They have a disproportionate impact on statistical conclusions and are often the result of errors. ==== Model confirmation ==== It is prudent to verify that the assumptions of ANOVA have been met. Residuals are examined or analyzed to confirm homoscedasticity and gross normality. Residuals should have the appearance of (zero mean normal distribution) noise when plotted as a function of anything including time and modeled data values. Trends hint at interactions among factors or among observations. One rule of thumb: "If the largest standard deviation is less than twice the smallest standard deviation, we can use methods based on the assumption of equal standard deviations and our results will still be approximately correct." ==== Follow-up tests ==== A statistically significant effect in ANOVA is often followed up with one or more different follow-up tests. This can be done in order to assess which groups are different from which other groups or to test various other focused hypotheses. Follow-up tests are often distinguished in terms of whether they are planned (a priori) or post hoc. Planned tests are determined before looking at the data and post hoc tests are performed after looking at the data. Often one of the "treatments" is none, so the treatment group can act as a control. Dunnett's test (a modification of the t-test) tests whether each of the other treatment groups has the same mean as the control.Post hoc tests such as Tukey's range test most commonly compare every group mean with every other group mean and typically incorporate some method of controlling for Type I errors. Comparisons, which are most commonly planned, can be either simple or compound. Simple comparisons compare one group mean with one other group mean. Compound comparisons typically compare two sets of groups means where one set has two or more groups (e.g., compare average group means of group A, B and C with group D). Comparisons can also look at tests of trend, such as linear and quadratic relationships, when the independent variable involves ordered levels. Following ANOVA with pair-wise multiple-comparison tests has been criticized on several grounds. There are many such tests (10 in one table) and recommendations regarding their use are vague or conflicting. == Study designs == There are several types of ANOVA. Many statisticians base ANOVA on the design of the experiment, especially on the protocol that specifies the random assignment of treatments to subjects; the protocol's description of the assignment mechanism should include a specification of the structure of the treatments and of any blocking. It is also common to apply ANOVA to observational data using an appropriate statistical model.Some popular designs use the following types of ANOVA: One-way ANOVA is used to test for differences among two or more independent groups (means),e.g. different levels of urea application in a crop, or different levels of antibiotic action on several bacterial species, or different levels of effect of some medicine on groups of patients. Typically, however, the one-way ANOVA is used to test for differences among at least three groups, since the two-group case can be covered by a t-test. When there are only two means to compare, the t-test and the ANOVA F-test are equivalent; the relation between ANOVA and t is given by F = t2. Factorial ANOVA is used when the experimenter wants to study the interaction effects among the treatments. Repeated measures ANOVA is used when the same subjects are used for each treatment (e.g., in a longitudinal study). Multivariate analysis of variance (MANOVA) is used when there is more than one response variable. == Cautions == Balanced experiments (those with an equal sample size for each treatment) are relatively easy to interpret; Unbalanced experiments offer more complexity. For single factor (one way) ANOVA, the adjustment for unbalanced data is easy, but the unbalanced analysis lacks both robustness and power. For more complex designs the lack of balance leads to further complications. "The orthogonality property of main effects and interactions present in balanced data does not carry over to the unbalanced case. This means that the usual analysis of variance techniques do not apply. Consequently, the analysis of unbalanced factorials is much more difficult than that for balanced designs." In the general case, "The analysis of variance can also be applied to unbalanced data, but then the sums of squares, mean squares, and F-ratios will depend on the order in which the sources of variation are considered." The simplest techniques for handling unbalanced data restore balance by either throwing out data or by synthesizing missing data. More complex techniques use regression. ANOVA is (in part) a significance test. The American Psychological Association holds the view that simply reporting significance is insufficient and that reporting confidence bounds is preferred.While ANOVA is conservative (in maintaining a significance level) against multiple comparisons in one dimension, it is not conservative against comparisons in multiple dimensions. == Generalizations == ANOVA is considered to be a special case of linear regression which in turn is a special case of the general linear model. All consider the observations to be the sum of a model (fit) and a residual (error) to be minimized. The Kruskal–Wallis test and the Friedman test are nonparametric tests, which do not rely on an assumption of normality. === Connection to linear regression === Below we make clear the connection between multi-way ANOVA and linear regression. Linearly re-order the data so that k th {\displaystyle k^{\text{th}}} observation is associated with a response y k {\displaystyle y_{k}} and factors Z k , b {\displaystyle Z_{k,b}} where b ∈ { 1 , 2 , … , B } {\displaystyle b\in \{1,2,\ldots ,B\}} denotes the different factors and B {\displaystyle B} is the total number of factors. In one-way ANOVA B = 1 {\displaystyle B=1} and in two-way ANOVA B = 2 {\displaystyle B=2} . Furthermore, we assume the b t h {\displaystyle b^{th}} factor has I b {\displaystyle I_{b}} levels. Now, we can one-hot encode the factors into the ∑ b = 1 B I b {\displaystyle \sum _{b=1}^{B}I_{b}} dimensional vector v k {\displaystyle v_{k}} . The one-hot encoding function g b : I b ↦ { 0 , 1 } I b {\displaystyle g_{b}:I_{b}\mapsto \{0,1\}^{I_{b}}} is defined such that the i t h {\displaystyle i^{th}} entry of g b ( Z k , b ) {\displaystyle g_{b}(Z_{k,b})} is The vector v k {\displaystyle v_{k}} is the concatenation of all of the above vectors for all b {\displaystyle b} . Thus, v k = [ g 1 ( Z k , 1 ) , g 2 ( Z k , 2 ) , … , g B ( Z k , B ) ] {\displaystyle v_{k}=[g_{1}(Z_{k,1}),g_{2}(Z_{k,2}),\ldots ,g_{B}(Z_{k,B})]} . In order to obtain a fully general B {\displaystyle B} -way interaction ANOVA we must also concatenate every additional interaction term in the vector v k {\displaystyle v_{k}} and then add an intercept term. Let that vector be x k {\displaystyle x_{k}} . With this notation in place, we now have the exact connection with linear regression. We simply regress response y k {\displaystyle y_{k}} against the vector X k {\displaystyle X_{k}} . However, there is a concern about identifiability. In order to overcome such issues we assume that the sum of the parameters within each set of interactions is equal to zero. From here, one can use F-statistics or other methods to determine the relevance of the individual factors. ==== Example ==== We can consider the 2-way interaction example where we assume that the first factor has 2 levels and the second factor has 3 levels. Define a i = 1 {\displaystyle a_{i}=1} if Z k , 1 = i {\displaystyle Z_{k,1}=i} and b i = 1 {\displaystyle b_{i}=1} if Z k , 2 = i {\displaystyle Z_{k,2}=i} , i.e. a {\displaystyle a} is the one-hot encoding of the first factor and b {\displaystyle b} is the one-hot encoding of the second factor. With that, where the last term is an intercept term. For a more concrete example suppose that Then, == See also == == Footnotes == == Notes == == References == Anscombe, F. J. (1948).

### Instruction: retrieve labels for this: United States appellate procedure involves the rules and regulations for filing appeals in state courts and federal courts. The nature of an appeal can vary greatly depending on the type of case and the rules of the court in the jurisdiction where the case was prosecuted. There are many types of standard of review for appeals, such as de novo and abuse of discretion. However, most appeals begin when a party files a petition for review to a higher court for the purpose of overturning the lower court's decision. An appellate court is a court that hears cases on appeal from another court. Depending on the particular legal rules that apply to each circumstance, a party to a court case who is unhappy with the result might be able to challenge that result in an appellate court on specific grounds. These grounds typically could include errors of law, fact, procedure or due process. In different jurisdictions, appellate courts are also called appeals courts, courts of appeals, superior courts, or supreme courts. The specific procedures for appealing, including even whether there is a right of appeal from a particular type of decision, can vary greatly from state to state. The right to file an appeal can also vary from state to state; for example, the New Jersey Constitution vests judicial power in a Supreme Court, a Superior Court, and other courts of limited jurisdiction, with an appellate court being part of the Superior Court. == Access to appellant status == A party who files an appeal is called an "appellant", "plaintiff in error", "petitioner" or "pursuer", and a party on the other side is called a "appellee". A "cross-appeal" is an appeal brought by the respondent. For example, suppose at trial the judge found for the plaintiff and ordered the defendant to pay $50,000. If the defendant files an appeal arguing that he should not have to pay any money, then the plaintiff might file a cross-appeal arguing that the defendant should have to pay $200,000 instead of $50,000. The appellant is the party who, having lost part or all their claim in a lower court decision, is appealing to a higher court to have their case reconsidered. This is usually done on the basis that the lower court judge erred in the application of law, but it may also be possible to appeal on the basis of court misconduct, or that a finding of fact was entirely unreasonable to make on the evidence. The appellant in the new case can be either the plaintiff (or claimant), defendant, third-party intervenor, or respondent (appellee) from the lower case, depending on who was the losing party. The winning party from the lower court, however, is now the respondent. In unusual cases the appellant can be the victor in the court below, but still appeal. An appellee is the party to an appeal in which the lower court judgment was in its favor. The appellee is required to respond to the petition, oral arguments, and legal briefs of the appellant. In general, the appellee takes the procedural posture that the lower court's decision should be affirmed. == Ability to appeal == An appeal "as of right" is one that is guaranteed by statute or some underlying constitutional or legal principle. The appellate court cannot refuse to listen to the appeal. An appeal "by leave" or "permission" requires the appellant to obtain leave to appeal; in such a situation either or both of the lower court and the court may have the discretion to grant or refuse the appellant's demand to appeal the lower court's decision. In the Supreme Court, review in most cases is available only if the Court exercises its discretion and grants a writ of certiorari.In tort, equity, or other civil matters either party to a previous case may file an appeal. In criminal matters, however, the state or prosecution generally has no appeal "as of right". And due to the double jeopardy principle, the state or prosecution may never appeal a jury or bench verdict of acquittal. But in some jurisdictions, the state or prosecution may appeal "as of right" from a trial court's dismissal of an indictment in whole or in part or from a trial court's granting of a defendant's suppression motion. Likewise, in some jurisdictions, the state or prosecution may appeal an issue of law "by leave" from the trial court or the appellate court. The ability of the prosecution to appeal a decision in favor of a defendant varies significantly internationally. All parties must present grounds to appeal, or it will not be heard. By convention in some law reports, the appellant is named first. This can mean that where it is the defendant who appeals, the name of the case in the law reports reverses (in some cases twice) as the appeals work their way up the court hierarchy. This is not always true, however. In the federal courts, the parties' names always stay in the same order as the lower court when an appeal is taken to the circuit courts of appeals, and are re-ordered only if the appeal reaches the Supreme Court. == Direct or collateral: Appealing criminal convictions == Many jurisdictions recognize two types of appeals, particularly in the criminal context. The first is the traditional "direct" appeal in which the appellant files an appeal with the next higher court of review. The second is the collateral appeal or post-conviction petition, in which the petitioner-appellant files the appeal in a court of first instance—usually the court that tried the case. The key distinguishing factor between direct and collateral appeals is that the former occurs in state courts, and the latter in federal courts.Relief in post-conviction is rare and is most often found in capital or violent felony cases. The typical scenario involves an incarcerated defendant locating DNA evidence demonstrating the defendant's actual innocence. === Appellate review === "Appellate review" is the general term for the process by which courts with appellate jurisdiction take jurisdiction of matters decided by lower courts. It is distinguished from judicial review, which refers to the court's overriding constitutional or statutory right to determine if a legislative act or administrative decision is defective for jurisdictional or other reasons (which may vary by jurisdiction). In most jurisdictions the normal and preferred way of seeking appellate review is by filing an appeal of the final judgment. Generally, an appeal of the judgment will also allow appeal of all other orders or rulings made by the trial court in the course of the case. This is because such orders cannot be appealed "as of right". However, certain critical interlocutory court orders, such as the denial of a request for an interim injunction, or an order holding a person in contempt of court, can be appealed immediately although the case may otherwise not have been fully disposed of. There are two distinct forms of appellate review, "direct" and "collateral". For example, a criminal defendant may be convicted in state court, and lose on "direct appeal" to higher state appellate courts, and if unsuccessful, mount a "collateral" action such as filing for a writ of habeas corpus in the federal courts. Generally speaking, "[d]irect appeal statutes afford defendants the opportunity to challenge the merits of a judgment and allege errors of law or fact. ... [Collateral review], on the other hand, provide[s] an independent and civil inquiry into the validity of a conviction and sentence, and as such are generally limited to challenges to constitutional, jurisdictional, or other fundamental violations that occurred at trial." "Graham v. Borgen", 483 F 3d. 475 (7th Cir. 2007) (no. 04-4103) (slip op. at 7) (citation omitted). In Anglo-American common law courts, appellate review of lower court decisions may also be obtained by filing a petition for review by prerogative writ in certain cases. There is no corresponding right to a writ in any pure or continental civil law legal systems, though some mixed systems such as Quebec recognize these prerogative writs. ==== Direct Appeal ==== After exhausting the first appeal as of right, defendants usually petition the highest state court to review the decision. This appeal is known as a direct appeal. The highest state court, generally known as the Supreme Court, exercises discretion over whether it will review the case. On direct appeal, a prisoner challenges the grounds of the conviction based on an error that occurred at trial or some other stage in the adjudicative process. ===== Preservation Issues ===== An appellant's claim(s) must usually be preserved at trial. This means that the defendant had to object to the error when it occurred in the trial. Because constitutional claims are of great magnitude, appellate courts might be more lenient to review the claim even if it was not preserved. For example, Connecticut applies the following standard to review unpreserved claims: 1.the record is adequate to review the alleged claim of error; 2. the claim is of constitutional magnitude alleging the violation of a fundamental right; 3. the alleged constitutional violation clearly exists and clearly deprived the defendant of a fair trial; 4. if subject to harmless error analysis, the state has failed to demonstrate harmlessness of the alleged constitutional violation beyond a reasonable doubt. ==== State Post Conviction Relief: Collateral Appeal ==== All States have a post-conviction relief process. Similar to federal post-conviction relief, an appellant can petition the court to correct alleged fundamental errors that were not corrected on direct review. Typical claims might include ineffective assistance of counsel and actual innocence based on new evidence. These proceedings are normally separate from the direct appeal, however some states allow for collateral relief to be sought on direct appeal. After direct appeal, the conviction is considered final. An appeal from the post conviction court proceeds just as a direct appeal. That is, it goes to the intermediate appellate court, followed by the highest court. If the petition is granted the appellant could be released from incarceration, the sentence could be modified, or a new trial could be ordered. ==== Habeas Corpus ==== == Notice of appeal == A "notice of appeal" is a form or document that in many cases is required to begin an appeal. The form is completed by the appellant or by the appellant's legal representative. The nature of this form can vary greatly from country to country and from court to court within a country. The specific rules of the legal system will dictate exactly how the appeal is officially begun. For example, the appellant might have to file the notice of appeal with the appellate court, or with the court from which the appeal is taken, or both. Some courts have samples of a notice of appeal on the court's own web site. In New Jersey, for example, the Administrative Office of the Court has promulgated a form of notice of appeal for use by appellants, though using this exact form is not mandatory and the failure to use it is not a jurisdictional defect provided that all pertinent information is set forth in whatever form of notice of appeal is used.The deadline for beginning an appeal can often be very short: traditionally, it is measured in days, not months. This can vary from country to country, as well as within a country, depending on the specific rules in force. In the U.S. federal court system, criminal defendants must file a notice of appeal within 10 days of the entry of either the judgment or the order being appealed, or the right to appeal is forfeited. == Appellate procedure == Generally speaking the appellate court examines the record of evidence presented in the trial court and the law that the lower court applied and decides whether that decision was legally sound or not. The appellate court will typically be deferential to the lower court's findings of fact (such as whether a defendant committed a particular act), unless clearly erroneous, and so will focus on the court's application of the law to those facts (such as whether the act found by the court to have occurred fits a legal definition at issue). If the appellate court finds no defect, it "affirms" the judgment. If the appellate court does find a legal defect in the decision "below" (i.e., in the lower court), it may "modify" the ruling to correct the defect, or it may nullify ("reverse" or "vacate") the whole decision or any part of it. It may, in addition, send the case back ("remand" or "remit") to the lower court for further proceedings to remedy the defect. In some cases, an appellate court may review a lower court decision "de novo" (or completely), challenging even the lower court's findings of fact. This might be the proper standard of review, for example, if the lower court resolved the case by granting a pre-trial motion to dismiss or motion for summary judgment which is usually based only upon written submissions to the trial court and not on any trial testimony. Another situation is where appeal is by way of "re-hearing". Certain jurisdictions permit certain appeals to cause the trial to be heard afresh in the appellate court. Sometimes, the appellate court finds a defect in the procedure the parties used in filing the appeal and dismisses the appeal without considering its merits, which has the same effect as affirming the judgment below. (This would happen, for example, if the appellant waited too long, under the appellate court's rules, to file the appeal.) Generally, there is no trial in an appellate court, only consideration of the record of the evidence presented to the trial court and all the pre-trial and trial court proceedings are reviewed—unless the appeal is by way of re-hearing, new evidence will usually only be considered on appeal in "very" rare instances, for example if that material evidence was unavailable to a party for some very significant reason such as prosecutorial misconduct. In some systems, an appellate court will only consider the written decision of the lower court, together with any written evidence that was before that court and is relevant to the appeal. In other systems, the appellate court will normally consider the record of the lower court. In those cases the record will first be certified by the lower court. The appellant has the opportunity to present arguments for the granting of the appeal and the appellee (or respondent) can present arguments against it. Arguments of the parties to the appeal are presented through their appellate lawyers, if represented, or "pro se" if the party has not engaged legal representation. Those arguments are presented in written briefs and sometimes in oral argument to the court at a hearing. At such hearings each party is allowed a brief presentation at which the appellate judges ask questions based on their review of the record below and the submitted briefs. In an adversarial system, appellate courts do not have the power to review lower court decisions unless a party appeals it. Therefore, if a lower court has ruled in an improper manner, or against legal precedent, that judgment will stand if not appealed – even if it might have been overturned on appeal. The United States legal system generally recognizes two types of appeals: a trial "de novo" or an appeal on the record. A trial de novo is usually available for review of informal proceedings conducted by some minor judicial tribunals in proceedings that do not provide all the procedural attributes of a formal judicial trial. If unchallenged, these decisions have the power to settle more minor legal disputes once and for all. If a party is dissatisfied with the finding of such a tribunal, one generally has the power to request a trial "de novo" by a court of record. In such a proceeding, all issues and evidence may be developed newly, as though never heard before, and one is not restricted to the evidence heard in the lower proceeding. Sometimes, however, the decision of the lower proceeding is itself admissible as evidence, thus helping to curb frivolous appeals. In some cases, an application for "trial de novo" effectively erases the prior trial as if it had never taken place. The Supreme Court of Virginia has stated that '"This Court has repeatedly held that the effect of an appeal to circuit court is to "annul the judgment of the inferior tribunal as completely as if there had been no previous trial."' The only exception to this is that if a defendant appeals a conviction for a crime having multiple levels of offenses, where they are convicted on a lesser offense, the appeal is of the lesser offense; the conviction represents an acquittal of the more serious offenses. "[A] trial on the same charges in the circuit court does not violate double jeopardy principles, . . . subject only to the limitation that conviction in [the] district court for an offense lesser included in the one charged constitutes an acquittal of the greater offense, permitting trial de novo in the circuit court only for the lesser-included offense."In an appeal on the record from a decision in a judicial proceeding, both appellant and respondent are bound to base their arguments wholly on the proceedings and body of evidence as they were presented in the lower tribunal. Each seeks to prove to the higher court that the result they desired was the just result. Precedent and case law figure prominently in the arguments. In order for the appeal to succeed, the appellant must prove that the lower court committed reversible error, that is, an impermissible action by the court acted to cause a result that was unjust, and which would not have resulted had the court acted properly. Some examples of reversible error would be erroneously instructing the jury on the law applicable to the case, permitting seriously improper argument by an attorney, admitting or excluding evidence improperly, acting outside the court's jurisdiction, injecting bias into the proceeding or appearing to do so, juror misconduct, etc. The failure to formally object at the time, to what one views as improper action in the lower court, may result in the affirmance of the lower court's judgment on the grounds that one did not "preserve the issue for appeal" by objecting. In cases where a judge rather than a jury decided issues of fact, an appellate court will apply an "abuse of discretion" standard of review. Under this standard, the appellate court gives deference to the lower court's view of the evidence, and reverses its decision only if it were a clear abuse of discretion. This is usually defined as a decision outside the bounds of reasonableness. On the other hand, the appellate court normally gives less deference to a lower court's decision on issues of law, and may reverse if it finds that the lower court applied the wrong legal standard. In some cases, an appellant may successfully argue that the law under which the lower decision was rendered was unconstitutional or otherwise invalid, or may convince the higher court to order a new trial on the basis that evidence earlier sought was concealed or only recently discovered. In the case of new evidence, there must be a high probability that its presence or absence would have made a material difference in the trial. Another issue suitable for appeal in criminal cases is effective assistance of counsel. If a defendant has been convicted and can prove that his lawyer did not adequately handle his case and that there is a reasonable probability that the result of the trial would have been different had the lawyer given competent representation, he is entitled to a new trial. A lawyer traditionally starts an oral argument to any appellate court with the words "May it please the court." After an appeal is heard, the "mandate" is a formal notice of a decision by a court of appeal; this notice is transmitted to the trial court and, when filed by the clerk of the trial court, constitutes the final judgment on the case, unless the appeal court has directed further proceedings in the trial court. The mandate is distinguished from the appeal court's opinion, which sets out the legal reasoning for its decision. In some jurisdictions the mandate is known as the "remittitur". == Results == The result of an appeal can be: Affirmed: Where the reviewing court basically agrees with the result of the lower courts ruling(s). Reversed: Where the reviewing court basically disagrees with the result of the lower courts ruling(s), and overturns their decision. Vacated: Where the reviewing court overturns the lower courts ruling(s) as invalid, without necessarily disagreeing with it/them, e.g. because the case was decided on the basis of a legal principle that no longer applies. Remanded: Where the reviewing court sends the case back to the lower court.There can be multiple outcomes, so that the reviewing court can affirm some rulings, reverse others and remand the case all at the same time. Remand is not required where there is nothing left to do in the case. "Generally speaking, an appellate court's judgment provides 'the final directive of the appeals courts as to the matter appealed, setting out with specificity the court's determination that the action appealed from should be affirmed, reversed, remanded or modified'".Some reviewing courts who have discretionary review may send a case back without comment other than review improvidently granted. In other words, after looking at the case, they chose not to say anything. The result for the case of review improvidently granted is effectively the same as affirmed, but without that extra higher court stamp of approval. == See also == Appellate court Appellee Civil procedure Court of Appeals Courts-martial in the United States Criminal procedure Defendant Interlocutory appeal List of legal topics Petition for stay Plaintiff Pursuer Reversible error Supreme Court of the United States Writ of Certiorari Writ of habeas corpus Writ of mandamus List of wrongful convictions in the United States == References == ### Answer: <Legal procedure>, <United States appellate procedure>, <United States procedural law>

### Instruction: retrieve labels for this: An appellate court, commonly called an appeals court, court of appeals (American English), appeal court (British English), court of second instance or second instance court, is any court of law that is empowered to hear an appeal of a trial court or other lower tribunal. In most jurisdictions, the court system is divided into at least three levels: the trial court, which initially hears cases and reviews evidence and testimony to determine the facts of the case; at least one intermediate appellate court; and a supreme court (or court of last resort) which primarily reviews the decisions of the intermediate courts. A jurisdiction's supreme court is that jurisdiction's highest appellate court. Appellate courts nationwide can operate under varying rules.The authority of appellate courts to review the decisions of lower courts varies widely from one jurisdiction to another. In some areas, the appellate court has limited powers of review. Generally, an appellate court's judgment provides the final directive of the appeals courts as to the matter appealed, setting out with specificity the court's determination that the action appealed from should be affirmed, reversed, remanded or modified. == New Zealand == The Court of Appeal of New Zealand, located in Wellington, is New Zealand's principal intermediate appellate court. In practice, most appeals are resolved at this intermediate appellate level, rather than in the Supreme Court. == Sri Lanka == The Court of Appeal of Sri Lanka, located in Colombo, is the second senior court in the Sri Lankan legal system. == United States == In the United States, both state and federal appellate courts are usually restricted to examining whether the lower court made the correct legal determinations, rather than hearing direct evidence and determining what the facts of the case were. Furthermore, U.S. appellate courts are usually restricted to hearing appeals based on matters that were originally brought up before the trial court. Hence, such an appellate court will not consider an appellant's argument if it is based on a theory that is raised for the first time in the appeal.In most U.S. states, and in U.S. federal courts, parties before the court are allowed one appeal as of right. This means that a party who is unsatisfied with the outcome of a trial may bring an appeal to contest that outcome. However, appeals may be costly, and the appellate court must find an error on the part of the court below that justifies upsetting the verdict. Therefore, only a small proportion of trial court decisions result in appeals. Some appellate courts, particularly supreme courts, have the power of discretionary review, meaning that they can decide whether they will hear an appeal brought in a particular case. === Institutional titles === Many U.S. jurisdictions title their appellate court an court of appeal or court of appeals. Historically, others have titled their appellate court a court of errors (or court of errors and appeals), on the premise that it was intended to correct errors made by lower courts. Examples of such courts include the New Jersey Court of Errors and Appeals (which existed from 1844 to 1947), the Connecticut Supreme Court of Errors (which has been renamed the Connecticut Supreme Court), the Kentucky Court of Errors (renamed the Kentucky Supreme Court), and the Mississippi High Court of Errors and Appeals (since renamed the Supreme Court of Mississippi). In some jurisdictions, a court able to hear appeals is known as an appellate division. The phrase "court of appeals" most often refers to intermediate appellate courts. However, the Maryland and New York systems are different. The Maryland Court of Appeals and the New York Court of Appeals are the highest appellate courts in those states. The New York Supreme Court is a trial court of general jurisdiction. Depending on the system, certain courts may serve as both trial courts and appellate courts, hearing appeals of decisions made by courts with more limited jurisdiction. Some jurisdictions have specialized appellate courts, such as the Texas Court of Criminal Appeals, which only hears appeals raised in criminal cases, and the United States Court of Appeals for the Federal Circuit, which has general jurisdiction but derives most of its caseload from patent cases, on one hand, and appeals from the Court of Federal Claims on the other. == See also == Court of Criminal Appeal (disambiguation) Court of Criminal Appeals (disambiguation) Court of Appeal (Hong Kong) High Court (Hong Kong) Court of Appeal (England and Wales) == References == Lax, Jeffrey R.

### Instruction: retrieve labels for this: "America the Beautiful" is an American patriotic song. The lyrics were written by Katharine Lee Bates, and the music was composed by church organist and choirmaster Samuel A. Ward at Grace Episcopal Church in Newark, New Jersey. The two never met.Bates originally wrote the words as a poem, "Pikes Peak", first published in the Fourth of July edition of the church periodical The Congregationalist in 1895. At that time, the poem was titled "America" for publication. Ward had originally written the music, "Materna", for the hymn "O Mother dear, Jerusalem" in 1882, though it was not first published until 1892. Ward's music combined with the Bates poem was first published in 1910 and titled America the Beautiful. The song is one of the most popular of the many U.S. patriotic songs. == History == In 1893, at the age of 33, Bates, an English professor at Wellesley College, had taken a train trip to Colorado Springs, Colorado, to teach a short summer school session at Colorado College. Several of the sights on her trip inspired her, and they found their way into her poem, including the World's Columbian Exposition in Chicago, the "White City" with its promise of the future contained within its gleaming white buildings; the wheat fields of America's heartland Kansas, through which her train was riding on July 16; and the majestic view of the Great Plains from high atop Pikes Peak.On the pinnacle of that mountain, the words of the poem started to come to her, and she wrote them down upon returning to her hotel room at the original Antlers Hotel. The poem was initially published two years later in The Congregationalist to commemorate the Fourth of July. It quickly caught the public's fancy. Amended versions were published in 1904 and 1911. The first known melody written for the song was sent in by Silas Pratt when the poem was published in The Congregationalist. By 1900, at least 75 different melodies had been written. A hymn tune composed in 1882 by Samuel A. Ward, the organist and choir director at Grace Church, Newark, was generally considered the best music as early as 1910 and is still the popular tune today. Just as Bates had been inspired to write her poem, Ward, too, was inspired. The tune came to him while he was on a ferryboat trip from Coney Island back to his home in New York City after a leisurely summer day and he immediately wrote it down. Supposedly, he was so anxious to capture the tune in his head, he asked fellow passenger friend Harry Martin for his shirt cuff to write the tune on. He composed the tune for the old hymn "O Mother Dear, Jerusalem", retitling the work "Materna". Ward's music combined with Bates's poem were first published together in 1910 and titled "America the Beautiful".Ward died in 1903, not knowing the national stature his music would attain since the music was only first applied to the song in 1904. Bates was more fortunate since the song's popularity was well established by the time of her death in 1929.At various times in the more than 100 years that have elapsed since the song was written, particularly during the John F. Kennedy administration, there have been efforts to give "America the Beautiful" legal status either as a national hymn or as a national anthem equal to, or in place of, "The Star-Spangled Banner", but so far this has not succeeded. Proponents prefer "America the Beautiful" for various reasons, saying it is easier to sing, more melodic, and more adaptable to new orchestrations while still remaining as easily recognizable as "The Star-Spangled Banner". Some prefer "America the Beautiful" over "The Star-Spangled Banner" due to the latter's war-oriented imagery. Others prefer "The Star-Spangled Banner" for the same reason. While that national dichotomy has stymied any effort at changing the tradition of the national anthem, "America the Beautiful" continues to be held in high esteem by a large number of Americans.This song was used as the background music of the television broadcast of the Tiangong-1 launch.The song is often included in songbooks in a wide variety of religious congregations in the United States. == Lyrics == == Popular versions == Bing Crosby included the song in a medley on his album 101 Gang Songs (1961). In 1976, while the United States celebrated its bicentennial, a soulful version popularized by Ray Charles peaked at number 98 on the US R&B Charts and is included on the soundtrack for the movie The Sandlot. Three different renditions of the song have entered the Hot Country Songs charts. The first was by Charlie Rich, which went to number 22 in 1976. A second, by Mickey Newbury, peaked at number 82 in 1980. An all-star version of "America the Beautiful" performed by country singers Trace Adkins, Sherrié Austin, Billy Dean, Vince Gill, Carolyn Dawn Johnson, Toby Keith, Brenda Lee, Lonestar, Lyle Lovett, Lila McCann, Lorrie Morgan, Jamie O'Neal, The Oak Ridge Boys, Collin Raye, Kenny Rogers, Keith Urban and Phil Vassar reached number 58 in July 2001. The song re-entered the chart following the September 11 attacks.A punk rock adaptation of the song was recorded in 1976 by New York band The Dictators, and released on their album Every Day is Saturday.Popularity of the song increased greatly following the September 11 attacks; at some sporting events it was sung in addition to the traditional singing of the national anthem. During the first taping of the Late Show with David Letterman following the attacks, CBS newsman Dan Rather cried briefly as he quoted the fourth verse.For Super Bowl XLVIII, The Coca-Cola Company aired a multilingual version of the song, sung in several different languages. The commercial received some criticism on social media sites, such as Twitter and Facebook, and from some conservatives, such as Glenn Beck. Despite the controversies, Coca-Cola later reused the Super Bowl ad during Super Bowl LI, the opening ceremonies of the 2014 Winter Olympics and 2016 Summer Olympics and for patriotic holidays. == Idioms == "From sea to shining sea", originally used in the charters of some of the English Colonies in North America, is an American idiom meaning "from the Atlantic Ocean to the Pacific Ocean" (or vice versa). Other songs that have used this phrase include the American patriotic song "God Bless the U.S.A." and Schoolhouse Rock's "Elbow Room". The phrase and the song are also the namesake of the Shining Sea Bikeway, a bike path in Bates's hometown of Falmouth, Massachusetts. The phrase is similar to the Latin phrase "A Mari Usque Ad Mare" ("From sea to sea"), which serves as the official motto of Canada."Purple mountain majesties" refers to the shade of the Pikes Peak in Colorado Springs, Colorado, which inspired Bates to write the poem. == Books == Lynn Sherr's 2001 book America the Beautiful discusses the origins of the song and the backgrounds of its authors in depth. The book points out that the poem has the same meter as that of "Auld Lang Syne"; the songs can be sung interchangeably. Additionally, Sherr discusses the evolution of the lyrics, for instance, changes to the original third verse written by Bates. The song appears in Ellen Raskin's The Westing Game. == References == == Further reading == Collins, Ace. Songs Sung, Red, White, and Blue: The Stories Behind America's Best-Loved Patriotic Songs.

### Instruction: retrieve labels for this: Assistive technology is an umbrella term that includes assistive, adaptive, and rehabilitative devices for people with disabilities while also including the process used in selecting, locating, and using them. People who have disabilities often have difficulty performing activities of daily living (ADLs) independently, or even with assistance. ADLs are self-care activities that include toileting, mobility (ambulation), eating, bathing, dressing and grooming. Assistive technology can ameliorate the effects of disabilities that limit the ability to perform ADLs. Assistive technology promotes greater independence by enabling people to perform tasks they were formerly unable to accomplish, or had great difficulty accomplishing, by providing enhancements to, or changing methods of interacting with, the technology needed to accomplish such tasks. For example, wheelchairs provide independent mobility for those who cannot walk, while assistive eating devices can enable people who cannot feed themselves to do so. Due to assistive technology, people with disabilities have an opportunity of a more positive and easygoing lifestyle, with an increase in "social participation," "security and control," and a greater chance to "reduce institutional costs without significantly increasing household expenses." == Adaptive Technology == The term adaptive technology is often used as the synonym for assistive technology; however, they are different terms. Assistive technology refers to "any item, piece of equipment, or product system, whether acquired commercially, modified, or customized, that is used to increase, maintain, or improve functional capabilities of individuals with disabilities", while adaptive technology covers items that are specifically designed for persons with disabilities and would seldom be used by non-disabled persons. In other words, "assistive technology is any object or system that increases or maintains the capabilities of people with disabilities," while adaptive technology is "any object or system that is specifically designed for the purpose of increasing or maintaining the capabilities of people with disabilities." Consequently, adaptive technology is a subset of assistive technology. Adaptive technology often refers specifically to electronic and information technology access. == Mobility impairments == === Wheelchairs === Wheelchairs are devices that can be manually propelled or electrically propelled, and that include a seating system and are designed to be a substitute for the normal mobility that most people enjoy. Wheelchairs and other mobility devices allow people to perform mobility-related activities of daily living which include feeding, toileting, dressing, grooming, and bathing. The devices come in a number of variations where they can be propelled either by hand or by motors where the occupant uses electrical controls to manage motors and seating control actuators through a joystick, sip-and-puff control, or other input devices. Often there are handles behind the seat for someone else to do the pushing or input devices for caregivers. Wheelchairs are used by people for whom walking is difficult or impossible due to illness, injury, or disability. People with both sitting and walking disability often need to use a wheelchair or walker. === Transfer devices === Patient transfer devices generally allow patients with impaired mobility to be moved by caregivers between beds, wheelchairs, commodes, toilets, chairs, stretchers, shower benches, automobiles, swimming pools, and other patient support systems (i.e., radiology, surgical, or examining tables). The most common devices are Patient lifts (for vertical transfer), Transfer benches, stretcher or convertible chairs (for lateral, supine transfer), sit-to-stand lifts (for moving patients from one seated position to another i.e., from wheelchairs to commodes), air bearing inflatable mattresses (for supine transfer i.e., transfer from a gurney to an operating room table), and sliding boards (usually used for transfer from a bed to a wheelchair). Highly dependent patients who cannot assist their caregiver in moving them often require a Patient lift (a floor or ceiling-suspended sling lift) which though invented in 1955 and in common use since the early 1960s is still considered the state-of-the-art transfer device by OSHA and the American Nursing Association. === Walkers === A walker or walking frame or Rollator is a tool for disabled people who need additional support to maintain balance or stability while walking. It consists of a frame that is about waist high, approximately twelve inches deep and slightly wider than the user. Walkers are also available in other sizes, such as for children, or for heavy people. Modern walkers are height-adjustable. The front two legs of the walker may or may not have wheels attached depending on the strength and abilities of the person using it. It is also common to see caster wheels or glides on the back legs of a walker with wheels on the front. === Prosthesis === A prosthesis, prosthetic, or prosthetic limb is a device that replaces a missing body part. It is part of the field of biomechatronics, the science of using mechanical devices with human muscle, skeleton, and nervous systems to assist or enhance motor control lost by trauma, disease, or defect. Prostheses are typically used to replace parts lost by injury (traumatic) or missing from birth (congenital) or to supplement defective body parts. Inside the body, artificial heart valves are in common use with artificial hearts and lungs seeing less common use but under active technology development. Other medical devices and aids that can be considered prosthetics include hearing aids, artificial eyes, palatal obturator, gastric bands, and dentures. Prostheses are specifically not orthoses, although given certain circumstances a prosthesis might end up performing some or all of the same functionary benefits as an orthosis. Prostheses are technically the complete finished item. For instance, a C-Leg knee alone is not a prosthesis, but only a prosthetic component. The complete prosthesis would consist of the attachment system to the residual limb — usually a "socket", and all the attachment hardware components all the way down to and including the terminal device. Keep this in mind as nomenclature is often interchanged. The terms "prosthetic" and "orthotic" are adjectives used to describe devices such as a prosthetic knee. The terms "prosthetics" and "orthotics" are used to describe the respective allied health fields. == Visual impairments == Many people with serious visual impairments live independently, using a wide range of tools and techniques. Examples of assistive technology for visually impairment include screen readers, screen magnifiers, Braille embossers, desktop video magnifiers, and voice recorders. === Screen readers === Screen readers are used to help the visually impaired to easily access electronic information. These software programs run on a computer in order to convey the displayed information through voice (text-to-speech) or braille (refreshable braille displays) in combination with magnification for low vision users in some cases. There are a variety of platforms and applications available for a variety of costs with differing feature sets. One example of screen readers is Apple VoiceOver. This software is provided free of charge on all Apple devices. Apple VoiceOver includes the option to magnify the screen, control the keyboard, and provide verbal descriptions to describe what is happening on the screen. There are thirty languages to select from. It also has the capacity to read aloud file content, as well as web pages, E-mail messages, and word processing files. === Braille and braille embossers === Braille is a system of raised dots formed into units called braille cells. A full braille cell is made up of six dots, with two parallel rows of three dots, but other combinations and quantities of dots represent other letters, numbers, punctuation marks, or words. People can then use their fingers to read the code of raised dots. A braille embosser is, simply put, a printer for braille. Instead of a standard printer adding ink onto a page, the braille embosser imprints the raised dots of braille onto a page. Some braille embossers combine both braille and ink so the documents can be read with either sight or touch. === Refreshable braille display === A refreshable braille display or braille terminal is an electro-mechanical device for displaying braille characters, usually by means of round-tipped pins raised through holes in a flat surface. Computer users who cannot use a computer monitor use it to read a braille output version of the displayed text. === Desktop video magnifier === Desktop video magnifiers are electronic devices that use a camera and a display screen to perform digital magnification of printed materials. They enlarge printed pages for those with low vision. A camera connects to a monitor that displays real-time images, and the user can control settings such as magnification, focus, contrast, underlining, highlighting, and other screen preferences. They come in a variety of sizes and styles; some are small and portable with handheld cameras, while others are much larger and mounted on a fixed stand. === Screen magnification software === A screen magnifier is software that interfaces with a computer's graphical output to present enlarged screen content. It allows users to enlarge the texts and graphics on their computer screens for easier viewing. Similar to desktop video magnifiers, this technology assists people with low vision. After the user loads the software into their computer's memory, it serves as a kind of "computer magnifying glass." Wherever the computer cursor moves, it enlarges the area around it. This allows greater computer accessibility for a wide range of visual abilities. === Large-print and tactile keyboards === A large-print keyboard has large letters printed on the keys. On the keyboard shown, the round buttons at the top control software which can magnify the screen (zoom in), change the background color of the screen, or make the mouse cursor on the screen larger. The "bump dots" on the keys, installed in this case by the organization using the keyboards, help the user find the right keys in a tactile way. === Navigation Assistance === Assistive technology for navigation has exploded on the IEEE Xplore database since 2000, with over 7,500 engineering articles written on assistive technologies and visual impairment in the past 25 years, and over 1,300 articles on solving the problem of navigation for people who are blind or visually impaired. As well, over 600 articles on augmented reality and visual impairment have appeared in the engineering literature since 2000. Most of these articles were published within the past 5 years, and the number of articles in this area is increasing every year. GPS, accelerometers, gyroscopes, and cameras can pinpoint the exact location of the user and provide information on what’s in the immediate vicinity, and assistance in getting to a destination. === Wearable Technology === Wearable technology are smart electronic devices that can be worn on the body as an implant or an accessory. New technologies are exploring how the visually impaired can receive visual information through wearable devices.Some wearable devices for visual impairment include: eSight Brainport == Personal emergency response systems == Personal emergency response systems (PERS), or Telecare (UK term), are a particular sort of assistive technology that use electronic sensors connected to an alarm system to help caregivers manage risk and help vulnerable people stay independent at home longer. An example would be the systems being put in place for senior people such as fall detectors, thermometers (for hypothermia risk), flooding and unlit gas sensors (for people with mild dementia). Notably, these alerts can be customized to the particular person's risks. When the alert is triggered, a message is sent to a caregiver or contact center who can respond appropriately. == Accessibility software == In human–computer interaction, computer accessibility (also known as accessible computing) refers to the accessibility of a computer system to all people, regardless of disability or severity of impairment, examples include web accessibility guidelines. Another approach is for the user to present a token to the computer terminal, such as a smart card, that has configuration information to adjust the computer speed, text size, etc. to their particular needs. This is useful where users want to access public computer based terminals in Libraries, ATM, Information kiosks etc. The concept is encompassed by the CEN EN 1332-4 Identification Card Systems - Man-Machine Interface. This development of this standard has been supported in Europe by SNAPI and has been successfully incorporated into the Lasseo specifications, but with limited success due to the lack of interest from public computer terminal suppliers. == Hearing impairments == The deaf or hard of hearing community has a difficult time to communicate and perceive information as compared to hearing individuals. Thus, these individuals often rely on visual and tactile mediums for receiving and communicating information. The use of assistive technology and devices provides this community with various solutions to their problems by providing higher sound (for those who are hard of hearing), tactile feedback, visual cues and improved technology access. Individuals who are deaf or hard of hearing utilize a variety of assistive technologies that provide them with improved access to information in numerous environments. Most devices either provide amplified sound or alternate ways to access information through vision and/or vibration. These technologies can be grouped into three general categories: Hearing Technology, alerting devices, and communication support. === Hearing aids === A hearing aid or deaf aid is an electroacoustic device which is designed to amplify sound for the wearer, usually with the aim of making speech more intelligible, and to correct impaired hearing as measured by audiometry. This type of assistive technology helps people with hearing loss participate more fully in their communities by allowing them to hear more clearly. They amplify any and all sound waves through use of a microphone, amplifier, and speaker. There is a wide variety of hearing aids available, including digital, in-the-ear, in-the-canal, behind-the-ear, and on-the-body aids. === Assistive listening devices === Assistive listening devices include FM, infrared, and loop assistive listening devices. This type of technology allows people with hearing difficulties to focus on a speaker or subject by getting rid of extra background noises and distractions, making places like auditoriums, classrooms, and meetings much easier to participate in. The assistive listening device usually uses a microphone to capture an audio source near to its origin and broadcast it wirelessly over an FM (Frequency Modulation) transmission, IR (Infra Red) transmission, IL (Induction Loop) transmission, or other transmission methods. The person who is listening may use an FM/IR/IL Receiver to tune into the signal and listen at his/her preferred volume. === Amplified telephone equipment === This type of assistive technology allows users to amplify the volume and clarity of their phone calls so that they can easily partake in this medium of communication. There are also options to adjust the frequency and tone of a call to suit their individual hearing needs. Additionally, there is a wide variety of amplified telephones to choose from, with different degrees of amplification. For example, a phone with 26 to 40 decibel is generally sufficient for mild hearing loss, while a phone with 71 to 90 decibel is better for more severe hearing loss. == Augmentative and alternative communication == Augmentative and alternative communication (AAC) is an umbrella term that encompasses methods of communication for those with impairments or restrictions on the production or comprehension of spoken or written language. AAC systems are extremely diverse and depend on the capabilities of the user. They may be as basic as pictures on a board that are used to request food, drink, or other care; or they can be advanced speech generating devices, based on speech synthesis, that are capable of storing hundreds of phrases and words. == Cognitive impairments == Assistive Technology for Cognition (ATC) is the use of technology (usually high tech) to augment and assist cognitive processes such as attention, memory, self-regulation, navigation, emotion recognition and management, planning, and sequencing activity. Systematic reviews of the field have found that the number of ATC are growing rapidly, but have focused on memory and planning, that there is emerging evidence for efficacy, that a lot of scope exists to develop new ATC. Examples of ATC include: NeuroPage which prompts users about meetings, Wakamaru, which provides companionship and reminds users to take medicine and calls for help if something is wrong, and telephone Reassurance systems. === Memory aids === Memory aids are any type of assistive technology that helps a user learn and remember certain information. Many memory aids are used for cognitive impairments such as reading, writing, or organizational difficulties. For example, a Smartpen records handwritten notes by creating both a digital copy and an audio recording of the text. Users simply tap certain parts of their notes, the pen saves it, and reads it back to them. From there, the user can also download their notes onto a computer for increased accessibility. Digital voice recorders are also used to record "in the moment" information for fast and easy recall at a later time. === Educational software === Educational software is software that assists people with reading, learning, comprehension, and organizational difficulties. Any accommodation software such as text readers, notetakers, text enlargers, organization tools, word predictions, and talking word processors falls under the category of educational software. == Eating Impairments == Adaptive eating devices include items commonly used by the general population like spoons and forks and plates. However they become assistive technology when they are modified to accommodate the needs of people who have difficultly using standard cutlery due to a disabling condition. Common modifications include increasing the size of the utensil handle to make it easier to grasp. Plates and bowls may have a guard on the edge that stops food being pushed off of the dish when it is being scooped. More sophisticated equipment for eating includes manual and powered feeding devices. These devices support those who have little or no hand and arm function and enable them to eat independently. == In sports == Assistive technology in sports is an area of technology design that is growing. Assistive technology is the array of new devices created to enable sports enthusiasts who have disabilities to play. Assistive technology may be used in adaptive sports, where an existing sport is modified to enable players with a disability to participate; or, assistive technology may be used to invent completely new sports with athletes with disabilities exclusively in mind. An increasing number of people with disabilities are participating in sports, leading to the development of new assistive technology. Assistive technology devices can be simple, or "low-tech", or they may use highly advanced technology. "Low-tech" devices can include velcro gloves and adaptive bands and tubes. "High-tech" devices can include all-terrain wheelchairs and adaptive bicycles. Accordingly, assistive technology can be found in sports ranging from local community recreation to the elite Paralympic Games. More complex assistive technology devices have been developed over time, and as a result, sports for people with disabilities "have changed from being a clinical therapeutic tool to an increasingly competition-oriented activity". == In education == In the United States there are two major pieces of legislation that govern the use of assistive technology within the school system. The first is Section 504 of the Rehabilitation Act of 1973 and the second being the Individuals with Disabilities Education Act (IDEA) which was first enacted in 1975 under the name The Education for All Handicapped Children Act. In 2004, during the reauthorization period for IDEA, the National Instructional Material Access Center (NIMAC) was created which provided a repository of accessible text including publisher's textbooks to students with a qualifying disability. Files provided are in XML format and used as a starting platform for braille readers, screen readers, and other digital text software. IDEA defines assistive technology as follows: "any item, piece of equipment, or product system, whether acquired commercially off the shelf, modified, or customized, that is used to increase, maintain, or improve functional capabilities of a child with a disability. (B) Exception.--The term does not include a medical device that is surgically implanted, or the replacement of such device."Assistive technology in this area is broken down into low, mid, and high tech categories. Low tech encompasses equipment that is often low cost and does not include batteries or requires charging. Examples include adapted paper and pencil grips for writing or masks and color overlays for reading. Mid tech supports used in the school setting include the use of handheld spelling dictionaries and portable word processors used to keyboard writing. High tech supports involve the use of tablet devices and computers with accompanying software. Software supports for writing include the use of auditory feedback while keyboarding, word prediction for spelling, and speech to text. Supports for reading include the use of text to speech (TTS) software and font modification via access to digital text. Limited supports are available for math instruction and mostly consist of grid based software to allow younger students to keyboard equations and auditory feedback of more complex equations using MathML and Daisy. == Computer accessibility == One of the largest problems that affect people with disabilities is discomfort with prostheses. An experiment performed in Massachusetts utilized 20 people with various sensors attached to their arms. The subjects tried different arm exercises, and the sensors recorded their movements. All of the data helped engineers develop new engineering concepts for prosthetics.Assistive technology may attempt to improve the ergonomics of the devices themselves such as Dvorak and other alternative keyboard layouts, which offer more ergonomic layouts of the keys. Assistive technology devices have been created to enable people with disabilities to use modern touch screen mobile computers such as the iPad, iPhone and iPod touch. The Pererro is a plug and play adapter for iOS devices which uses the built in Apple VoiceOver feature in combination with a basic switch. This brings touch screen technology to those who were previously unable to use it. Apple, with the release of iOS 7 had introduced the ability to navigate apps using switch control. Switch access could be activated either through an external bluetooth connected switch, single touch of the screen, or use of right and left head turns using the device's camera. Additional accessibility features include the use of Assistive Touch which allows a user to access multi-touch gestures through pre-programmed onscreen buttons. For users with physical disabilities a large variety of switches are available and customizable to the user's needs varying in size, shape, or amount of pressure required for activation. Switch access may be placed near any area of the body which has consistent and reliable mobility and less subject to fatigue. Common sites include the hands, head, and feet. Eye gaze and head mouse systems can also be used as an alternative mouse navigation. A user may utilize single or multiple switch sites and the process often involves a scanning through items on a screen and activating the switch once the desired object is highlighted. == Home automation == The form of home automation called assistive domotics focuses on making it possible for elderly and disabled people to live independently. Home automation is becoming a viable option for the elderly and disabled who would prefer to stay in their own homes rather than move to a healthcare facility. This field uses much of the same technology and equipment as home automation for security, entertainment, and energy conservation but tailors it towards elderly and disabled users. For example, automated prompts and reminders utilize motion sensors and pre-recorded audio messages; an automated prompt in the kitchen may remind the resident to turn off the oven, and one by the front door may remind the resident to lock the door. == Impacts == Overall, assistive technology aims to allow people with disabilities to "participate more fully in all aspects of life (home, school, and community)" and increases their opportunities for "education, social interactions, and potential for meaningful employment". It creates greater independence and control for disabled individuals. For example, in one study of 1,342 infants, toddlers and preschoolers, all with some kind of developmental, physical, sensory, or cognitive disability, the use of assistive technology created improvements in child development. These included improvements in "cognitive, social, communication, literacy, motor, adaptive, and increases in engagement in learning activities". Additionally, it has been found to lighten caregiver load. Both family and professional caregivers benefit from assistive technology. Through its use, the time that a family member or friend would need to care for a patient significantly decreases. However, studies show that care time for a professional caregiver increases when assistive technology is used. Nonetheless, their work load is significantly easier as the assistive technology frees them of having to perform certain tasks.There are several platforms that use machine learning to identify the appropriate assistive device to suggest to patients, making assistive devices more accessible. == See also == == References == SourcesAmerican Speech-Language-Hearing Association.

### Instruction: retrieve labels for this: The abacus (plural abaci or abacuses), also called a counting frame, is a calculating tool that was in use in Europe, China and Russia, centuries before the adoption of the written Hindu–Arabic numeral system. The exact origin of the abacus is still unknown. Today, abaci are often constructed as a bamboo frame with beads sliding on wires, but originally they were beans or stones moved in grooves in sand or on tablets of wood, stone, or metal. Abaci come in different designs. Some designs, like the bead frame consisting of beads divided into tens, are used mainly to teach arithmetic, although they remain popular in the post-Soviet states as a tool. Other designs, such as the Japanese soroban, have been used for practical calculations even involving several digits. For any particular abacus design, there usually are numerous different methods to perform a certain type of calculation, which may include basic operations like addition and multiplication, or even more complex ones, such as calculating square roots. Some of these methods may work with non-natural numbers (numbers such as 1.5 and ​3⁄4). Although today many use calculators and computers instead of abaci to calculate, abaci still remain in common use in some countries. Merchants, traders and clerks in some parts of Eastern Europe, Russia, China and Africa use abaci, and they are still used to teach arithmetic to children. Some people who are unable to use a calculator because of visual impairment may use an abacus. == Etymology == The use of the word abacus dates before 1387 AD, when a Middle English work borrowed the word from Latin to describe a sandboard abacus. The Latin word came from Greek ἄβαξ abax which means something without base, and improperly, any piece of rectangular board or plank. Alternatively, without reference to ancient texts on etymology, it has been suggested that it means "a square tablet strewn with dust", or "drawing-board covered with dust (for the use of mathematics)" (the exact shape of the Latin perhaps reflects the genitive form of the Greek word, ἄβακoς abakos). Whereas the table strewn with dust definition is popular, there are those that do not place credence in this at all and in fact state that it is not proven. Greek ἄβαξ itself is probably a borrowing of a Northwest Semitic, perhaps Phoenician, word akin to Hebrew ʾābāq (אבק), "dust" (or in post-Biblical sense meaning "sand used as a writing surface").The preferred plural of abacus is a subject of disagreement, with both abacuses and abaci in use. The user of an abacus is called an abacist. == History == === Mesopotamian === The period 2700–2300 BC saw the first appearance of the Sumerian abacus, a table of successive columns which delimited the successive orders of magnitude of their sexagesimal number system.Some scholars point to a character from the Babylonian cuneiform which may have been derived from a representation of the abacus. It is the belief of Old Babylonian scholars such as Carruccio that Old Babylonians "may have used the abacus for the operations of addition and subtraction; however, this primitive device proved difficult to use for more complex calculations". === Egyptian === The use of the abacus in Ancient Egypt is mentioned by the Greek historian Herodotus, who writes that the Egyptians manipulated the pebbles from right to left, opposite in direction to the Greek left-to-right method. Archaeologists have found ancient disks of various sizes that are thought to have been used as counters. However, wall depictions of this instrument have not been discovered. === Persian === During the Achaemenid Empire, around 600 BC the Persians first began to use the abacus. Under the Parthian, Sassanian and Iranian empires, scholars concentrated on exchanging knowledge and inventions with the countries around them – India, China, and the Roman Empire, when it is thought to have been exported to other countries. === Greek === The earliest archaeological evidence for the use of the Greek abacus dates to the 5th century BC. Also Demosthenes (384 BC–322 BC) talked of the need to use pebbles for calculations too difficult for your head. A play by Alexis from the 4th century BC mentions an abacus and pebbles for accounting, and both Diogenes and Polybius mention men that sometimes stood for more and sometimes for less, like the pebbles on an abacus. The Greek abacus was a table of wood or marble, pre-set with small counters in wood or metal for mathematical calculations. This Greek abacus saw use in Achaemenid Persia, the Etruscan civilization, Ancient Rome and, until the French Revolution, the Western Christian world. A tablet found on the Greek island Salamis in 1846 AD (the Salamis Tablet), dates back to 300 BC, making it the oldest counting board discovered so far. It is a slab of white marble 149 cm (59 in) long, 75 cm (30 in) wide, and 4.5 cm (2 in) thick, on which are 5 groups of markings. In the center of the tablet is a set of 5 parallel lines equally divided by a vertical line, capped with a semicircle at the intersection of the bottom-most horizontal line and the single vertical line. Below these lines is a wide space with a horizontal crack dividing it. Below this crack is another group of eleven parallel lines, again divided into two sections by a line perpendicular to them, but with the semicircle at the top of the intersection; the third, sixth and ninth of these lines are marked with a cross where they intersect with the vertical line. Also from this time frame the Darius Vase was unearthed in 1851. It was covered with pictures including a "treasurer" holding a wax tablet in one hand while manipulating counters on a table with the other. === Chinese === The earliest known written documentation of the Chinese abacus dates to the 2nd century BC.The Chinese abacus, known as the suanpan (算盤, lit. "counting tray"), is typically 20 cm (8 in) tall and comes in various widths depending on the operator. It usually has more than seven rods. There are two beads on each rod in the upper deck and five beads each in the bottom. The beads are usually rounded and made of a hardwood. The beads are counted by moving them up or down towards the beam; beads moved toward the beam are counted, while those moved away from it are not. The suanpan can be reset to the starting position instantly by a quick movement along the horizontal axis to spin all the beads away from the horizontal beam at the center. Suanpan can be used for functions other than counting. Unlike the simple counting board used in elementary schools, very efficient suanpan techniques have been developed to do multiplication, division, addition, subtraction, square root and cube root operations at high speed. There are currently schools teaching students how to use it. In the long scroll Along the River During the Qingming Festival painted by Zhang Zeduan during the Song dynasty (960–1297), a suanpan is clearly visible beside an account book and doctor's prescriptions on the counter of an apothecary's (Feibao). The similarity of the Roman abacus to the Chinese one suggests that one could have inspired the other, as there is some evidence of a trade relationship between the Roman Empire and China. However, no direct connection can be demonstrated, and the similarity of the abaci may be coincidental, both ultimately arising from counting with five fingers per hand. Where the Roman model (like most modern Korean and Japanese) has 4 plus 1 bead per decimal place, the standard suanpan has 5 plus 2. (Incidentally, this allows use with a hexadecimal numeral system, which was used for traditional Chinese measures of weight.) Instead of running on wires as in the Chinese, Korean, and Japanese models, the beads of Roman model run in grooves, presumably making arithmetic calculations much slower. Another possible source of the suanpan is Chinese counting rods, which operated with a decimal system but lacked the concept of zero as a place holder. The zero was probably introduced to the Chinese in the Tang dynasty (618–907) when travel in the Indian Ocean and the Middle East would have provided direct contact with India, allowing them to acquire the concept of zero and the decimal point from Indian merchants and mathematicians. === Roman === The normal method of calculation in ancient Rome, as in Greece, was by moving counters on a smooth table. Originally pebbles (calculi) were used. Later, and in medieval Europe, jetons were manufactured. Marked lines indicated units, fives, tens etc. as in the Roman numeral system. This system of 'counter casting' continued into the late Roman empire and in medieval Europe, and persisted in limited use into the nineteenth century. Due to Pope Sylvester II's reintroduction of the abacus with modifications, it became widely used in Europe once again during the 11th century This abacus used beads on wires, unlike the traditional Roman counting boards, which meant the abacus could be used much faster.Writing in the 1st century BC, Horace refers to the wax abacus, a board covered with a thin layer of black wax on which columns and figures were inscribed using a stylus.One example of archaeological evidence of the Roman abacus, shown here in reconstruction, dates to the 1st century AD. It has eight long grooves containing up to five beads in each and eight shorter grooves having either one or no beads in each. The groove marked I indicates units, X tens, and so on up to millions. The beads in the shorter grooves denote fives –five units, five tens etc., essentially in a bi-quinary coded decimal system, related to the Roman numerals. The short grooves on the right may have been used for marking Roman "ounces" (i.e. fractions). === Indian === The decimal number system invented in India replaced the abacus in Western Europe.The Abhidharmakośabhāṣya of Vasubandhu (316-396), a Sanskrit work on Buddhist philosophy, says that the second-century CE philosopher Vasumitra said that "placing a wick (Sanskrit vartikā) on the number one (ekāṅka) means it is a one, while placing the wick on the number hundred means it is called a hundred, and on the number one thousand means it is a thousand". It is unclear exactly what this arrangement may have been. Around the 5th century, Indian clerks were already finding new ways of recording the contents of the Abacus. Hindu texts used the term śūnya (zero) to indicate the empty column on the abacus. === Japanese === In Japanese, the abacus is called soroban (算盤, そろばん, lit. "Counting tray"), imported from China in the 14th century. It was probably in use by the working class a century or more before the ruling class started, as the class structure did not allow for devices used by the lower class to be adopted or used by the ruling class. The 1/4 abacus, which is suited to decimal calculation, appeared circa 1930, and became widespread as the Japanese abandoned hexadecimal weight calculation which was still common in China. The abacus is still manufactured in Japan today even with the proliferation, practicality, and affordability of pocket electronic calculators. The use of the soroban is still taught in Japanese primary schools as part of mathematics, primarily as an aid to faster mental calculation. Using visual imagery of a soroban, one can arrive at the answer in the same time as, or even faster than, is possible with a physical instrument. === Korean === The Chinese abacus migrated from China to Korea around 1400 AD. Koreans call it jupan (주판), supan (수판) or jusan (주산). === Native American === Some sources mention the use of an abacus called a nepohualtzintzin in ancient Aztec culture. This Mesoamerican abacus used a 5-digit base-20 system. The word Nepōhualtzintzin [nepoːwaɬˈt͡sint͡sin] comes from Nahuatl and it is formed by the roots; Ne – personal -; pōhual or pōhualli [ˈpoːwalːi] – the account -; and tzintzin [ˈt͡sint͡sin] – small similar elements. Its complete meaning was taken as: counting with small similar elements by somebody. Its use was taught in the Calmecac to the temalpouhqueh [temaɬˈpoʍkeʔ], who were students dedicated to take the accounts of skies, from childhood. The Nepōhualtzintzin was divided in two main parts separated by a bar or intermediate cord. In the left part there were four beads, which in the first row have unitary values (1, 2, 3, and 4), and in the right side there are three beads with values of 5, 10, and 15 respectively. In order to know the value of the respective beads of the upper rows, it is enough to multiply by 20 (by each row), the value of the corresponding account in the first row. Altogether, there were 13 rows with 7 beads in each one, which made up 91 beads in each Nepōhualtzintzin. This was a basic number to understand, 7 times 13, a close relation conceived between natural phenomena, the underworld and the cycles of the heavens. One Nepōhualtzintzin (91) represented the number of days that a season of the year lasts, two Nepōhualtzitzin (182) is the number of days of the corn's cycle, from its sowing to its harvest, three Nepōhualtzintzin (273) is the number of days of a baby's gestation, and four Nepōhualtzintzin (364) completed a cycle and approximate a year (11/4 days short). When translated into modern computer arithmetic, the Nepōhualtzintzin amounted to the rank from 10 to the 18 in floating point, which calculated stellar as well as infinitesimal amounts with absolute precision, meant that no round off was allowed. The rediscovery of the Nepōhualtzintzin was due to the Mexican engineer David Esparza Hidalgo, who in his wanderings throughout Mexico found diverse engravings and paintings of this instrument and reconstructed several of them made in gold, jade, encrustations of shell, etc. There have also been found very old Nepōhualtzintzin attributed to the Olmec culture, and even some bracelets of Mayan origin, as well as a diversity of forms and materials in other cultures. George I. Sanchez, "Arithmetic in Maya", Austin-Texas, 1961 found another base 5, base 4 abacus in the Yucatán Peninsula that also computed calendar data. This was a finger abacus, on one hand 0, 1, 2, 3, and 4 were used; and on the other hand 0, 1, 2 and 3 were used. Note the use of zero at the beginning and end of the two cycles. Sanchez worked with Sylvanus Morley, a noted Mayanist. The quipu of the Incas was a system of colored knotted cords used to record numerical data, like advanced tally sticks – but not used to perform calculations. Calculations were carried out using a yupana (Quechua for "counting tool"; see figure) which was still in use after the conquest of Peru. The working principle of a yupana is unknown, but in 2001 an explanation of the mathematical basis of these instruments was proposed by Italian mathematician Nicolino De Pasquale. By comparing the form of several yupanas, researchers found that calculations were based using the Fibonacci sequence 1, 1, 2, 3, 5 and powers of 10, 20 and 40 as place values for the different fields in the instrument. Using the Fibonacci sequence would keep the number of grains within any one field at a minimum. === Russian === The Russian abacus, the schoty (счёты), usually has a single slanted deck, with ten beads on each wire (except one wire, usually positioned near the user, with four beads for quarter-ruble fractions). Older models have another 4-bead wire for quarter-kopeks, which were minted until 1916. The Russian abacus is often used vertically, with wires from left to right in the manner of a book. The wires are usually bowed to bulge upward in the center, to keep the beads pinned to either of the two sides. It is cleared when all the beads are moved to the right. During manipulation, beads are moved to the left. For easy viewing, the middle 2 beads on each wire (the 5th and 6th bead) usually are of a different color from the other eight beads. Likewise, the left bead of the thousands wire (and the million wire, if present) may have a different color. As a simple, cheap and reliable device, the Russian abacus was in use in all shops and markets throughout the former Soviet Union, and the usage of it was taught in most schools until the 1990s. Even the 1874 invention of mechanical calculator, Odhner arithmometer, had not replaced them in Russia and likewise the mass production of Felix arithmometers since 1924 did not significantly reduce their use in the Soviet Union. The Russian abacus began to lose popularity only after the mass production of microcalculators had started in the Soviet Union in 1974. Today it is regarded as an archaism and replaced by the handheld calculator. The Russian abacus was brought to France around 1820 by the mathematician Jean-Victor Poncelet, who served in Napoleon's army and had been a prisoner of war in Russia. The abacus had fallen out of use in western Europe in the 16th century with the rise of decimal notation and algorismic methods. To Poncelet's French contemporaries, it was something new. Poncelet used it, not for any applied purpose, but as a teaching and demonstration aid. The Turks and the Armenian people also used abaci similar to the Russian schoty. It was named a coulba by the Turks and a choreb by the Armenians. == School abacus == Around the world, abaci have been used in pre-schools and elementary schools as an aid in teaching the numeral system and arithmetic. In Western countries, a bead frame similar to the Russian abacus but with straight wires and a vertical frame has been common (see image). It is still often seen as a plastic or wooden toy. The wire frame may be used either with positional notation like other abaci (thus the 10-wire version may represent numbers up to 9,999,999,999), or each bead may represent one unit (so that e.g. 74 can be represented by shifting all beads on 7 wires and 4 beads on the 8th wire, so numbers up to 100 may be represented). In the bead frame shown, the gap between the 5th and 6th wire, corresponding to the color change between the 5th and the 6th bead on each wire, suggests the latter use. The red-and-white abacus is used in contemporary primary schools for a wide range of number-related lessons. The twenty bead version, referred to by its Dutch name rekenrek ("calculating frame"), is often used, sometimes on a string of beads, sometimes on a rigid framework. == Renaissance abaci gallery == == Uses by the blind == An adapted abacus, invented by Tim Cranmer, called a Cranmer abacus is still commonly used by individuals who are blind. A piece of soft fabric or rubber is placed behind the beads so that they do not move inadvertently. This keeps the beads in place while the users feel or manipulate them. They use an abacus to perform the mathematical functions multiplication, division, addition, subtraction, square root and cube root.Although blind students have benefited from talking calculators, the abacus is still very often taught to these students in early grades, both in public schools and state schools for the blind. The abacus teaches mathematical skills that can never be replaced with talking calculators and is an important learning tool for blind students. Blind students also complete mathematical assignments using a braille-writer and Nemeth code (a type of braille code for mathematics) but large multiplication and long division problems can be long and difficult. The abacus gives blind and visually impaired students a tool to compute mathematical problems that equals the speed and mathematical knowledge required by their sighted peers using pencil and paper. Many blind people find this number machine a very useful tool throughout life. == Binary abacus == The binary abacus is used to explain how computers manipulate numbers. The abacus shows how numbers, letters, and signs can be stored in a binary system on a computer, or via ASCII. The device consists of a series of beads on parallel wires arranged in three separate rows. The beads represent a switch on the computer in either an "on" or "off" position. == See also == Chinese Zhusuan Chisanbop Logical abacus Mental abacus Napier's bones Sand table Slide rule Soroban Suanpan == Notes == == Footnotes == == References == == Further reading == == External links == Texts on Wikisource: "Abacus".

### Instruction: retrieve labels for this: An acid is a molecule or ion capable of donating a hydron (proton or hydrogen ion H+), or, alternatively, capable of forming a covalent bond with an electron pair (a Lewis acid).The first category of acids is the proton donors or Brønsted acids. In the special case of aqueous solutions, proton donors form the hydronium ion H3O+ and are known as Arrhenius acids. Brønsted and Lowry generalized the Arrhenius theory to include non-aqueous solvents. A Brønsted or Arrhenius acid usually contains a hydrogen atom bonded to a chemical structure that is still energetically favorable after loss of H+. Aqueous Arrhenius acids have characteristic properties which provide a practical description of an acid. Acids form aqueous solutions with a sour taste, can turn blue litmus red, and react with bases and certain metals (like calcium) to form salts. The word acid is derived from the Latin acidus/acēre meaning sour. An aqueous solution of an acid has a pH less than 7 and is colloquially also referred to as 'acid' (as in 'dissolved in acid'), while the strict definition refers only to the solute. A lower pH means a higher acidity, and thus a higher concentration of positive hydrogen ions in the solution. Chemicals or substances having the property of an acid are said to be acidic. Common aqueous acids include hydrochloric acid (a solution of hydrogen chloride which is found in gastric acid in the stomach and activates digestive enzymes), acetic acid (vinegar is a dilute aqueous solution of this liquid), sulfuric acid (used in car batteries), and citric acid (found in citrus fruits). As these examples show, acids (in the colloquial sense) can be solutions or pure substances, and can be derived from acids (in the strict sense) that are solids, liquids, or gases. Strong acids and some concentrated weak acids are corrosive, but there are exceptions such as carboranes and boric acid. The second category of acids are Lewis acids, which form a covalent bond with an electron pair. An example is boron trifluoride (BF3), whose boron atom has a vacant orbital which can form a covalent bond by sharing a lone pair of electrons on an atom in a base, for example the nitrogen atom in ammonia (NH3). Lewis considered this as a generalization of the Brønsted definition, so that an acid is a chemical species that accepts electron pairs either directly or by releasing protons (H+) into the solution, which then accept electron pairs. However, hydrogen chloride, acetic acid, and most other Brønsted-Lowry acids cannot form a covalent bond with an electron pair and are therefore not Lewis acids. Conversely, many Lewis acids are not Arrhenius or Brønsted-Lowry acids. In modern terminology, an acid is implicitly a Brønsted acid and not a Lewis acid, since chemists almost always refer to a Lewis acid explicitly as a Lewis acid. == Definitions and concepts == Modern definitions are concerned with the fundamental chemical reactions common to all acids. Most acids encountered in everyday life are aqueous solutions, or can be dissolved in water, so the Arrhenius and Brønsted-Lowry definitions are the most relevant. The Brønsted-Lowry definition is the most widely used definition; unless otherwise specified, acid-base reactions are assumed to involve the transfer of a proton (H+) from an acid to a base. Hydronium ions are acids according to all three definitions. Although alcohols and amines can be Brønsted-Lowry acids, they can also function as Lewis bases due to the lone pairs of electrons on their oxygen and nitrogen atoms. === Arrhenius acids === The Swedish chemist Svante Arrhenius attributed the properties of acidity to hydrogen ions (H+) or protons in 1884. An Arrhenius acid is a substance that, when added to water, increases the concentration of H+ ions in the water. Note that chemists often write H+(aq) and refer to the hydrogen ion when describing acid-base reactions but the free hydrogen nucleus, a proton, does not exist alone in water, it exists as the hydronium ion, H3O+. Thus, an Arrhenius acid can also be described as a substance that increases the concentration of hydronium ions when added to water. Examples include molecular substances such as HCl and acetic acid. An Arrhenius base, on the other hand, is a substance which increases the concentration of hydroxide (OH−) ions when dissolved in water. This decreases the concentration of hydronium because the ions react to form H2O molecules: H3O+(aq) + OH−(aq) ⇌ H2O(l) + H2O(l)Due to this equilibrium, any increase in the concentration of hydronium is accompanied by a decrease in the concentration of hydroxide. Thus, an Arrhenius acid could also be said to be one that decreases hydroxide concentration, while an Arrhenius base increases it. In an acidic solution, the concentration of hydronium ions is greater than 10−7 moles per liter. Since pH is defined as the negative logarithm of the concentration of hydronium ions, acidic solutions thus have a pH of less than 7. === Brønsted–Lowry acids === While the Arrhenius concept is useful for describing many reactions, it is also quite limited in its scope. In 1923 chemists Johannes Nicolaus Brønsted and Thomas Martin Lowry independently recognized that acid-base reactions involve the transfer of a proton. A Brønsted-Lowry acid (or simply Brønsted acid) is a species that donates a proton to a Brønsted-Lowry base. Brønsted-Lowry acid-base theory has several advantages over Arrhenius theory. Consider the following reactions of acetic acid (CH3COOH), the organic acid that gives vinegar its characteristic taste: CH3COOH + H2O ⇌ CH3COO− + H3O+ CH3COOH + NH3 ⇌ CH3COO− + NH+4Both theories easily describe the first reaction: CH3COOH acts as an Arrhenius acid because it acts as a source of H3O+ when dissolved in water, and it acts as a Brønsted acid by donating a proton to water. In the second example CH3COOH undergoes the same transformation, in this case donating a proton to ammonia (NH3), but does not relate to the Arrhenius definition of an acid because the reaction does not produce hydronium. Nevertheless, CH3COOH is both an Arrhenius and a Brønsted-Lowry acid. Brønsted-Lowry theory can be used to describe reactions of molecular compounds in nonaqueous solution or the gas phase. Hydrogen chloride (HCl) and ammonia combine under several different conditions to form ammonium chloride, NH4Cl. In aqueous solution HCl behaves as hydrochloric acid and exists as hydronium and chloride ions. The following reactions illustrate the limitations of Arrhenius's definition: H3O+(aq) + Cl−(aq) + NH3 → Cl−(aq) + NH+4(aq) + H2O HCl(benzene) + NH3(benzene) → NH4Cl(s) HCl(g) + NH3(g) → NH4Cl(s)As with the acetic acid reactions, both definitions work for the first example, where water is the solvent and hydronium ion is formed by the HCl solute. The next two reactions do not involve the formation of ions but are still proton-transfer reactions. In the second reaction hydrogen chloride and ammonia (dissolved in benzene) react to form solid ammonium chloride in a benzene solvent and in the third gaseous HCl and NH3 combine to form the solid. === Lewis acids === A third, only marginally related concept was proposed in 1923 by Gilbert N. Lewis, which includes reactions with acid-base characteristics that do not involve a proton transfer. A Lewis acid is a species that accepts a pair of electrons from another species; in other words, it is an electron pair acceptor. Brønsted acid-base reactions are proton transfer reactions while Lewis acid-base reactions are electron pair transfers. Many Lewis acids are not Brønsted-Lowry acids. Contrast how the following reactions are described in terms of acid-base chemistry: In the first reaction a fluoride ion, F−, gives up an electron pair to boron trifluoride to form the product tetrafluoroborate. Fluoride "loses" a pair of valence electrons because the electrons shared in the B—F bond are located in the region of space between the two atomic nuclei and are therefore more distant from the fluoride nucleus than they are in the lone fluoride ion. BF3 is a Lewis acid because it accepts the electron pair from fluoride. This reaction cannot be described in terms of Brønsted theory because there is no proton transfer. The second reaction can be described using either theory. A proton is transferred from an unspecified Brønsted acid to ammonia, a Brønsted base; alternatively, ammonia acts as a Lewis base and transfers a lone pair of electrons to form a bond with a hydrogen ion. The species that gains the electron pair is the Lewis acid; for example, the oxygen atom in H3O+ gains a pair of electrons when one of the H—O bonds is broken and the electrons shared in the bond become localized on oxygen. Depending on the context, a Lewis acid may also be described as an oxidizer or an electrophile. Organic Brønsted acids, such as acetic, citric, or oxalic acid, are not Lewis acids. They dissociate in water to produce a Lewis acid, H+, but at the same time also yield an equal amount of a Lewis base (acetate, citrate, or oxalate, respectively, for the acids mentioned). Few, if any, of the acids discussed in the following are Lewis acids. == Dissociation and equilibrium == Reactions of acids are often generalized in the form HA ⇌ H+ + A−, where HA represents the acid and A− is the conjugate base. This reaction is referred to as protolysis. The protonated form (HA) of an acid is also sometimes referred to as the free acid.Acid-base conjugate pairs differ by one proton, and can be interconverted by the addition or removal of a proton (protonation and deprotonation, respectively). Note that the acid can be the charged species and the conjugate base can be neutral in which case the generalized reaction scheme could be written as HA+ ⇌ H+ + A. In solution there exists an equilibrium between the acid and its conjugate base. The equilibrium constant K is an expression of the equilibrium concentrations of the molecules or the ions in solution. Brackets indicate concentration, such that [H2O] means the concentration of H2O. The acid dissociation constant Ka is generally used in the context of acid-base reactions. The numerical value of Ka is equal to the product of the concentrations of the products divided by the concentration of the reactants, where the reactant is the acid (HA) and the products are the conjugate base and H+. K a = [ H + ] [ A − ] [ HA ] {\displaystyle K_{a}={\frac {{\ce {[H+] [A^-]}}}{{\ce {[HA]}}}}} The stronger of two acids will have a higher Ka than the weaker acid; the ratio of hydrogen ions to acid will be higher for the stronger acid as the stronger acid has a greater tendency to lose its proton. Because the range of possible values for Ka spans many orders of magnitude, a more manageable constant, pKa is more frequently used, where pKa = −log10 Ka. Stronger acids have a smaller pKa than weaker acids. Experimentally determined pKa at 25 °C in aqueous solution are often quoted in textbooks and reference material. == Nomenclature == In the classical naming system, acids are named according to their anions. That ionic suffix is dropped and replaced with a new suffix (and sometimes prefix), according to the table below. For example, HCl has chloride as its anion, so the -ide suffix makes it take the form hydrochloric acid. In the IUPAC naming system, "aqueous" is simply added to the name of the ionic compound. Thus, for hydrogen chloride, the IUPAC name would be aqueous hydrogen chloride. The prefix "hydro-" is added only if the acid is made up of just hydrogen and one other element. Classical naming system: == Acid strength == The strength of an acid refers to its ability or tendency to lose a proton. A strong acid is one that completely dissociates in water; in other words, one mole of a strong acid HA dissolves in water yielding one mole of H+ and one mole of the conjugate base, A−, and none of the protonated acid HA. In contrast, a weak acid only partially dissociates and at equilibrium both the acid and the conjugate base are in solution. Examples of strong acids are hydrochloric acid (HCl), hydroiodic acid (HI), hydrobromic acid (HBr), perchloric acid (HClO4), nitric acid (HNO3) and sulfuric acid (H2SO4). In water each of these essentially ionizes 100%. The stronger an acid is, the more easily it loses a proton, H+. Two key factors that contribute to the ease of deprotonation are the polarity of the H—A bond and the size of atom A, which determines the strength of the H—A bond. Acid strengths are also often discussed in terms of the stability of the conjugate base. Stronger acids have a larger Ka and a more negative pKa than weaker acids. Sulfonic acids, which are organic oxyacids, are a class of strong acids. A common example is toluenesulfonic acid (tosylic acid). Unlike sulfuric acid itself, sulfonic acids can be solids. In fact, polystyrene functionalized into polystyrene sulfonate is a solid strongly acidic plastic that is filterable. Superacids are acids stronger than 100% sulfuric acid. Examples of superacids are fluoroantimonic acid, magic acid and perchloric acid. Superacids can permanently protonate water to give ionic, crystalline hydronium "salts". They can also quantitatively stabilize carbocations. While Ka measures the strength of an acid compound, the strength of an aqueous acid solution is measured by pH, which is an indication of the concentration of hydronium in the solution. The pH of a simple solution of an acid compound in water is determined by the dilution of the compound and the compound's Ka. == Chemical characteristics == === Monoprotic acids === Monoprotic acids are those acids that are able to donate one proton per molecule during the process of dissociation (sometimes called ionization) as shown below (symbolized by HA): HA(aq) + H2O(l) ⇌ H3O+(aq) + A−(aq) KaCommon examples of monoprotic acids in mineral acids include hydrochloric acid (HCl) and nitric acid (HNO3). On the other hand, for organic acids the term mainly indicates the presence of one carboxylic acid group and sometimes these acids are known as monocarboxylic acid. Examples in organic acids include formic acid (HCOOH), acetic acid (CH3COOH) and benzoic acid (C6H5COOH). === Polyprotic acids === Polyprotic acids, also known as polybasic acids, are able to donate more than one proton per acid molecule, in contrast to monoprotic acids that only donate one proton per molecule. Specific types of polyprotic acids have more specific names, such as diprotic acid (two potential protons to donate) and triprotic acid (three potential protons to donate). A diprotic acid (here symbolized by H2A) can undergo one or two dissociations depending on the pH. Each dissociation has its own dissociation constant, Ka1 and Ka2. H2A(aq) + H2O(l) ⇌ H3O+(aq) + HA−(aq) Ka1 HA−(aq) + H2O(l) ⇌ H3O+(aq) + A2−(aq) Ka2The first dissociation constant is typically greater than the second; i.e., Ka1 > Ka2. For example, sulfuric acid (H2SO4) can donate one proton to form the bisulfate anion (HSO−4), for which Ka1 is very large; then it can donate a second proton to form the sulfate anion (SO2−4), wherein the Ka2 is intermediate strength. The large Ka1 for the first dissociation makes sulfuric a strong acid. In a similar manner, the weak unstable carbonic acid (H2CO3) can lose one proton to form bicarbonate anion (HCO−3) and lose a second to form carbonate anion (CO2−3). Both Ka values are small, but Ka1 > Ka2 . A triprotic acid (H3A) can undergo one, two, or three dissociations and has three dissociation constants, where Ka1 > Ka2 > Ka3. H3A(aq) + H2O(l) ⇌ H3O+(aq) + H2A−(aq) Ka1 H2A−(aq) + H2O(l) ⇌ H3O+(aq) + HA2−(aq) Ka2 HA2−(aq) + H2O(l) ⇌ H3O+(aq) + A3−(aq) Ka3An inorganic example of a triprotic acid is orthophosphoric acid (H3PO4), usually just called phosphoric acid. All three protons can be successively lost to yield H2PO−4, then HPO2−4, and finally PO3−4, the orthophosphate ion, usually just called phosphate. Even though the positions of the three protons on the original phosphoric acid molecule are equivalent, the successive Ka values differ since it is energetically less favorable to lose a proton if the conjugate base is more negatively charged. An organic example of a triprotic acid is citric acid, which can successively lose three protons to finally form the citrate ion. Although the subsequent loss of each hydrogen ion is less favorable, all of the conjugate bases are present in solution. The fractional concentration, α (alpha), for each species can be calculated. For example, a generic diprotic acid will generate 3 species in solution: H2A, HA−, and A2−. The fractional concentrations can be calculated as below when given either the pH (which can be converted to the [H+]) or the concentrations of the acid with all its conjugate bases: α H 2 A = [ H + ] 2 [ H + ] 2 + [ H + ] K 1 + K 1 K 2 = [ H 2 A ] [ H 2 A ] + [ HA − ] + [ A 2 − ] α HA − = [ H + ] K 1 [ H + ] 2 + [ H + ] K 1 + K 1 K 2 = [ HA − ] [ H 2 A ] + [ HA − ] + [ A 2 − ] α A 2 − = K 1 K 2 [ H + ] 2 + [ H + ] K 1 + K 1 K 2 = [ A 2 − ] [ H 2 A ] + [ HA − ] + [ A 2 − ] {\displaystyle {\begin{aligned}\alpha _{\ce {H2A}}&={\frac {\ce {[H+]^{2}}}{{\ce {[H+]^{2}}}+[{\ce {H+}}]K_{1}+K_{1}K_{2}}}={\frac {\ce {[H2A]}}{\ce {{[H2A]}+{[HA^{-}]}+{[A^{2-}]}}}}\\\alpha _{\ce {HA^{-}}}&={\frac {[{\ce {H+}}]K_{1}}{{\ce {[H+]^{2}}}+[{\ce {H+}}]K_{1}+K_{1}K_{2}}}={\frac {\ce {[HA^{-}]}}{\ce {{[H2A]}+{[HA^{-}]}+{[A^{2-}]}}}}\\\alpha _{\ce {A^{2-}}}&={\frac {K_{1}K_{2}}{{\ce {[H+]^{2}}}+[{\ce {H+}}]K_{1}+K_{1}K_{2}}}={\frac {\ce {[A^{2-}]}}{\ce {{[H2A]}+{[HA^{-}]}+{[A^{2-}]}}}}\end{aligned}}} A plot of these fractional concentrations against pH, for given K1 and K2, is known as a Bjerrum plot. A pattern is observed in the above equations and can be expanded to the general n -protic acid that has been deprotonated i -times: α H n − i A i − = [ H + ] n − i ∏ j = 0 i K j ∑ i = 0 n [ [ H + ] n − i ∏ j = 0 i K j ] {\displaystyle \alpha _{{{\ce {H}}}_{n-i}A^{i-}}={{[{{\ce {H+}}}]^{n-i}\displaystyle \prod _{j=0}^{i}K_{j}} \over {\displaystyle \sum _{i=0}^{n}{\Big [}[{{\ce {H+}}}]^{n-i}\displaystyle \prod _{j=0}^{i}K_{j}}{\Big ]}}} where K0 = 1 and the other K-terms are the dissociation constants for the acid. === Neutralization === Neutralization is the reaction between an acid and a base, producing a salt and neutralized base; for example, hydrochloric acid and sodium hydroxide form sodium chloride and water: HCl(aq) + NaOH(aq) → H2O(l) + NaCl(aq)Neutralization is the basis of titration, where a pH indicator shows equivalence point when the equivalent number of moles of a base have been added to an acid. It is often wrongly assumed that neutralization should result in a solution with pH 7.0, which is only the case with similar acid and base strengths during a reaction. Neutralization with a base weaker than the acid results in a weakly acidic salt. An example is the weakly acidic ammonium chloride, which is produced from the strong acid hydrogen chloride and the weak base ammonia. Conversely, neutralizing a weak acid with a strong base gives a weakly basic salt, e.g. sodium fluoride from hydrogen fluoride and sodium hydroxide. === Weak acid–weak base equilibrium === In order for a protonated acid to lose a proton, the pH of the system must rise above the pKa of the acid. The decreased concentration of H+ in that basic solution shifts the equilibrium towards the conjugate base form (the deprotonated form of the acid). In lower-pH (more acidic) solutions, there is a high enough H+ concentration in the solution to cause the acid to remain in its protonated form. Solutions of weak acids and salts of their conjugate bases form buffer solutions. == Applications of acids == There are numerous uses for acids. Acids are often used to remove rust and other corrosion from metals in a process known as pickling. They may be used as an electrolyte in a wet cell battery, such as sulfuric acid in a car battery. Strong acids, sulfuric acid in particular, are widely used in mineral processing. For example, phosphate minerals react with sulfuric acid to produce phosphoric acid for the production of phosphate fertilizers, and zinc is produced by dissolving zinc oxide into sulfuric acid, purifying the solution and electrowinning. In the chemical industry, acids react in neutralization reactions to produce salts. For example, nitric acid reacts with ammonia to produce ammonium nitrate, a fertilizer. Additionally, carboxylic acids can be esterified with alcohols, to produce esters. Acids are used as additives to drinks and foods, as they alter their taste and serve as preservatives. Phosphoric acid, for example, is a component of cola drinks. Acetic acid is used in day-to-day life as vinegar. Carbonic acid is an important part of some cola drinks and soda. Citric acid is used as a preservative in sauces and pickles. Tartaric acid is an important component of some commonly used foods like unripened mangoes and tamarind. Natural fruits and vegetables also contain acids. Citric acid is present in oranges, lemon and other citrus fruits. Oxalic acid is present in tomatoes, spinach, and especially in carambola and rhubarb; rhubarb leaves and unripe carambolas are toxic because of high concentrations of oxalic acid. Ascorbic acid (Vitamin C) is an essential vitamin for the human body and is present in such foods as amla (Indian gooseberry), lemon, citrus fruits, and guava. Certain acids are used as drugs. Acetylsalicylic acid (Aspirin) is used as a pain killer and for bringing down fevers. Acids play important roles in the human body. The hydrochloric acid present in the stomach aids digestion by breaking down large and complex food molecules. Amino acids are required for synthesis of proteins required for growth and repair of body tissues. Fatty acids are also required for growth and repair of body tissues. Nucleic acids are important for the manufacturing of DNA and RNA and transmitting of traits to offspring through genes. Carbonic acid is important for maintenance of pH equilibrium in the body. === Acid catalysis === Acids are used as catalysts in industrial and organic chemistry; for example, sulfuric acid is used in very large quantities in the alkylation process to produce gasoline. Some acids, such as sulfuric, phosphoric, and hydrochloric acids, also effect dehydration and condensation reactions. In biochemistry, many enzymes employ acid catalysis. == Biological occurrence == Many biologically important molecules are acids. Nucleic acids, which contain acidic phosphate groups, include DNA and RNA. Nucleic acids contain the genetic code that determines many of an organism's characteristics, and is passed from parents to offspring. DNA contains the chemical blueprint for the synthesis of proteins which are made up of amino acid subunits. Cell membranes contain fatty acid esters such as phospholipids. An α-amino acid has a central carbon (the α or alpha carbon) which is covalently bonded to a carboxyl group (thus they are carboxylic acids), an amino group, a hydrogen atom and a variable group. The variable group, also called the R group or side chain, determines the identity and many of the properties of a specific amino acid. In glycine, the simplest amino acid, the R group is a hydrogen atom, but in all other amino acids it is contains one or more carbon atoms bonded to hydrogens, and may contain other elements such as sulfur, oxygen or nitrogen. With the exception of glycine, naturally occurring amino acids are chiral and almost invariably occur in the L-configuration. Peptidoglycan, found in some bacterial cell walls contains some D-amino acids. At physiological pH, typically around 7, free amino acids exist in a charged form, where the acidic carboxyl group (-COOH) loses a proton (-COO−) and the basic amine group (-NH2) gains a proton (-NH+3). The entire molecule has a net neutral charge and is a zwitterion, with the exception of amino acids with basic or acidic side chains. Aspartic acid, for example, possesses one protonated amine and two deprotonated carboxyl groups, for a net charge of −1 at physiological pH. Fatty acids and fatty acid derivatives are another group of carboxylic acids that play a significant role in biology. These contain long hydrocarbon chains and a carboxylic acid group on one end. The cell membrane of nearly all organisms is primarily made up of a phospholipid bilayer, a micelle of hydrophobic fatty acid esters with polar, hydrophilic phosphate "head" groups. Membranes contain additional components, some of which can participate in acid-base reactions. In humans and many other animals, hydrochloric acid is a part of the gastric acid secreted within the stomach to help hydrolyze proteins and polysaccharides, as well as converting the inactive pro-enzyme, pepsinogen into the enzyme, pepsin. Some organisms produce acids for defense; for example, ants produce formic acid. Acid-base equilibrium plays a critical role in regulating mammalian breathing. Oxygen gas (O2) drives cellular respiration, the process by which animals release the chemical potential energy stored in food, producing carbon dioxide (CO2) as a byproduct. Oxygen and carbon dioxide are exchanged in the lungs, and the body responds to changing energy demands by adjusting the rate of ventilation. For example, during periods of exertion the body rapidly breaks down stored carbohydrates and fat, releasing CO2 into the blood stream. In aqueous solutions such as blood CO2 exists in equilibrium with carbonic acid and bicarbonate ion. CO2 + H2O ⇌ H2CO3 ⇌ H+ + HCO−3It is the decrease in pH that signals the brain to breathe faster and deeper, expelling the excess CO2 and resupplying the cells with O2. Cell membranes are generally impermeable to charged or large, polar molecules because of the lipophilic fatty acyl chains comprising their interior. Many biologically important molecules, including a number of pharmaceutical agents, are organic weak acids which can cross the membrane in their protonated, uncharged form but not in their charged form (i.e. as the conjugate base). For this reason the activity of many drugs can be enhanced or inhibited by the use of antacids or acidic foods. The charged form, however, is often more soluble in blood and cytosol, both aqueous environments. When the extracellular environment is more acidic than the neutral pH within the cell, certain acids will exist in their neutral form and will be membrane soluble, allowing them to cross the phospholipid bilayer. Acids that lose a proton at the intracellular pH will exist in their soluble, charged form and are thus able to diffuse through the cytosol to their target.

### Instruction: retrieve labels for this: Asphalt, also known as bitumen (UK: , US: ), is a sticky, black, and highly viscous liquid or semi-solid form of petroleum. It may be found in natural deposits or may be a refined product, and is classed as a pitch. Before the 20th century, the term asphaltum was also used. The word is derived from the Ancient Greek ἄσφαλτος ásphaltos. The primary use (70%) of asphalt is in road construction, where it is used as the glue or binder mixed with aggregate particles to create asphalt concrete. Its other main uses are for bituminous waterproofing products, including production of roofing felt and for sealing flat roofs.The terms "asphalt" and "bitumen" are often used interchangeably to mean both natural and manufactured forms of the substance. In American English, "asphalt" (or "asphalt cement") is commonly used for a refined residue from the distillation process of selected crude oils. Outside the United States, the product is often called "bitumen", and geologists worldwide often prefer the term for the naturally occurring variety. Common colloquial usage often refers to various forms of asphalt as "tar", as in the name of the La Brea Tar Pits. Naturally occurring asphalt is sometimes specified by the term "crude bitumen". Its viscosity is similar to that of cold molasses while the material obtained from the fractional distillation of crude oil boiling at 525 °C (977 °F) is sometimes referred to as "refined bitumen". The Canadian province of Alberta has most of the world's reserves of natural asphalt in the Athabasca oil sands, which cover 142,000 square kilometres (55,000 sq mi), an area larger than England. == Terminology == === Etymology === The word "asphalt" is derived from the late Middle English, in turn from French asphalte, based on Late Latin asphalton, asphaltum, which is the latinisation of the Greek ἄσφαλτος (ásphaltos, ásphalton), a word meaning "asphalt/bitumen/pitch", which perhaps derives from ἀ-, "without" and σφάλλω (sfallō), "make fall". The first use of asphalt by the ancients was in the nature of a cement for securing or joining together various objects, and it thus seems likely that the name itself was expressive of this application. Specifically, Herodotus mentioned that bitumen was brought to Babylon to build its gigantic fortification wall. From the Greek, the word passed into late Latin, and thence into French (asphalte) and English ("asphaltum" and "asphalt"). In French, the term asphalte is used for naturally occurring asphalt-soaked limestone deposits, and for specialised manufactured products with fewer voids or greater bitumen content than the "asphaltic concrete" used to pave roads. The expression "bitumen" originated in the Sanskrit words jatu, meaning "pitch", and jatu-krit, meaning "pitch creating" or "pitch producing" (referring to coniferous or resinous trees). The Latin equivalent is claimed by some to be originally gwitu-men (pertaining to pitch), and by others, pixtumens (exuding or bubbling pitch), which was subsequently shortened to bitumen, thence passing via French into English. From the same root is derived the Anglo-Saxon word cwidu (mastix), the German word Kitt (cement or mastic) and the old Norse word kvada. === Modern terminology === In British English, "bitumen" is used instead of "asphalt". The word "asphalt" is instead used to refer to asphalt concrete, a mixture of construction aggregate and asphalt itself (also called "tarmac" in common parlance). Bitumen mixed with clay was usually called "asphaltum", but the term is less commonly used today.In Australian English, "bitumen" is often used as the generic term for road surfaces. In American English, "asphalt" is equivalent to the British "bitumen". However, "asphalt" is also commonly used as a shortened form of "asphalt concrete" (therefore equivalent to the British "asphalt" or "tarmac"). In Canadian English, the word "bitumen" is used to refer to the vast Canadian deposits of extremely heavy crude oil, while "asphalt" is used for the oil refinery product. Diluted bitumen (diluted with naphtha to make it flow in pipelines) is known as "dilbit" in the Canadian petroleum industry, while bitumen "upgraded" to synthetic crude oil is known as "syncrude", and syncrude blended with bitumen is called "synbit"."Bitumen" is still the preferred geological term for naturally occurring deposits of the solid or semi-solid form of petroleum. "Bituminous rock" is a form of sandstone impregnated with bitumen. The tar sands of Alberta, Canada are a similar material. Neither of the terms "asphalt" or "bitumen" should be confused with tar or coal tars. == Composition == === Normal composition === The components of asphalt include four main classes of compounds: Naphthene aromatics (naphthalene), consisting of partially hydrogenated polycyclic aromatic compounds Polar aromatics, consisting of high molecular weight phenols and carboxylic acids produced by partial oxidation of the material Saturated hydrocarbons; the percentage of saturated compounds in asphalt correlates with its softening point Asphaltenes, consisting of high molecular weight phenols and heterocyclic compoundsThe naphthene aromatics and polar aromatics are typically the majority components. Most natural bitumens also contain organosulfur compounds, resulting in an overall sulfur content of up to 4%. Nickel and vanadium are found at <10 parts per million, as is typical of some petroleum.The substance is soluble in carbon disulfide. It is commonly modelled as a colloid, with asphaltenes as the dispersed phase and maltenes as the continuous phase. "It is almost impossible to separate and identify all the different molecules of asphalt, because the number of molecules with different chemical structure is extremely large".Asphalt may be confused with coal tar, which is a visually similar black, thermoplastic material produced by the destructive distillation of coal. During the early and mid-20th century, when town gas was produced, coal tar was a readily available byproduct and extensively used as the binder for road aggregates. The addition of coal tar to macadam roads led to the word "tarmac", which is now used in common parlance to refer to road-making materials. However, since the 1970s, when natural gas succeeded town gas, asphalt has completely overtaken the use of coal tar in these applications. Other examples of this confusion include the La Brea Tar Pits and the Canadian oil sands, both of which actually contain natural bitumen rather than tar. "Pitch" is another term sometimes informally used at times to refer to asphalt, as in Pitch Lake. === Additives, mixtures and contaminants === For economic and other reasons, asphalt is sometimes sold combined with other materials, often without being labeled as anything other than simply "asphalt."Of particular note, in the 21st century, is the use of re-refined engine oil bottoms -- "REOB" or "REOBs" -- the residue of recycled autmotive engine oil, collected from the bottoms of re-refining vaccuum distillation towers. It contains the various non-refined elements and compounds in recycled engine oil, leftover from the re-refining process -- both additives to the original oil, and materials accumulating from its circulation in the engine (typically iron and copper). Some research has indicated a correlation between this contamination of asphalt and poorer-performing pavement. == Occurrence == The majority of asphalt used commercially is obtained from petroleum. Nonetheless, large amounts of asphalt occur in concentrated form in nature. Naturally occurring deposits of bitumen are formed from the remains of ancient, microscopic algae (diatoms) and other once-living things. These remains were deposited in the mud on the bottom of the ocean or lake where the organisms lived. Under the heat (above 50 °C) and pressure of burial deep in the earth, the remains were transformed into materials such as bitumen, kerogen, or petroleum. Natural deposits of bitumen include lakes such as the Pitch Lake in Trinidad and Tobago and Lake Bermudez in Venezuela. Natural seeps occur in the La Brea Tar Pits and in the Dead Sea. Bitumen also occurs in unconsolidated sandstones known as "oil sands" in Alberta, Canada, and the similar "tar sands" in Utah, US. The Canadian province of Alberta has most of the world's reserves, in three huge deposits covering 142,000 square kilometres (55,000 sq mi), an area larger than England or New York state. These bituminous sands contain 166 billion barrels (26.4×10^9 m3) of commercially established oil reserves, giving Canada the third largest oil reserves in the world. Although historically it was used without refining to pave roads, nearly all of the output is now used as raw material for oil refineries in Canada and the United States.The world's largest deposit of natural bitumen, known as the Athabasca oil sands, is located in the McMurray Formation of Northern Alberta. This formation is from the early Cretaceous, and is composed of numerous lenses of oil-bearing sand with up to 20% oil. Isotopic studies show the oil deposits to be about 110 million years old. Two smaller but still very large formations occur in the Peace River oil sands and the Cold Lake oil sands, to the west and southeast of the Athabasca oil sands, respectively. Of the Alberta deposits, only parts of the Athabasca oil sands are shallow enough to be suitable for surface mining. The other 80% has to be produced by oil wells using enhanced oil recovery techniques like steam-assisted gravity drainage.Much smaller heavy oil or bitumen deposits also occur in the Uinta Basin in Utah, US. The Tar Sand Triangle deposit, for example, is roughly 6% bitumen.Bitumen may occur in hydrothermal veins. An example of this is within the Uinta Basin of Utah, in the US, where there is a swarm of laterally and vertically extensive veins composed of a solid hydrocarbon termed Gilsonite. These veins formed by the polymerization and solidification of hydrocarbons that were mobilized from the deeper oil shales of the Green River Formation during burial and diagenesis.Bitumen is similar to the organic matter in carbonaceous meteorites. However, detailed studies have shown these materials to be distinct. The vast Alberta bitumen resources are considered to have started out as living material from marine plants and animals, mainly algae, that died millions of years ago when an ancient ocean covered Alberta. They were covered by mud, buried deeply over time, and gently cooked into oil by geothermal heat at a temperature of 50 to 150 °C (120 to 300 °F). Due to pressure from the rising of the Rocky Mountains in southwestern Alberta, 80 to 55 million years ago, the oil was driven northeast hundreds of kilometres and trapped into underground sand deposits left behind by ancient river beds and ocean beaches, thus forming the oil sands. == History == === Ancient times === The use of natural bitumen for waterproofing, and as an adhesive dates at least to the fifth millennium BC, with a crop storage basket discovered in Mehrgarh, of the Indus Valley Civilization, lined with it. By the 3rd millennia BC refined rock asphalt was in use, in the region, and was used to waterproof the Great Bath, Mohenjo-daro. In the ancient Middle East, the Sumerians used natural bitumen deposits for mortar between bricks and stones, to cement parts of carvings, such as eyes, into place, for ship caulking, and for waterproofing. The Greek historian Herodotus said hot bitumen was used as mortar in the walls of Babylon.The 1 kilometre (0.62 mi) long Euphrates Tunnel beneath the river Euphrates at Babylon in the time of Queen Semiramis (ca. 800 BC) was reportedly constructed of burnt bricks covered with bitumen as a waterproofing agent.Bitumen was used by ancient Egyptians to embalm mummies. The Persian word for asphalt is moom, which is related to the English word mummy. The Egyptians' primary source of bitumen was the Dead Sea, which the Romans knew as Palus Asphaltites (Asphalt Lake). Approximately 40 AD, Dioscorides described the Dead Sea material as Judaicum bitumen, and noted other places in the region where it could be found. The Sidon bitumen is thought to refer to material found at Hasbeya. Pliny refers also to bitumen being found in Epirus. It was a valuable strategic resource, the object of the first known battle for a hydrocarbon deposit—between the Seleucids and the Nabateans in 312 BC.In the ancient Far East, natural bitumen was slowly boiled to get rid of the higher fractions, leaving a thermoplastic material of higher molecular weight that when layered on objects became quite hard upon cooling. This was used to cover objects that needed waterproofing, such as scabbards and other items. Statuettes of household deities were also cast with this type of material in Japan, and probably also in China. In North America, archaeological recovery has indicated bitumen was sometimes used to adhere stone projectile points to wooden shafts. In Canada, aboriginal people used bitumen seeping out of the banks of the Athabasca and other rivers to waterproof birch bark canoes, and also heated it in smudge pots to ward off mosquitoes in the summer. === Continental Europe === In 1553, Pierre Belon described in his work Observations that pissasphalto, a mixture of pitch and bitumen, was used in the Republic of Ragusa (now Dubrovnik, Croatia) for tarring of ships.An 1838 edition of Mechanics Magazine cites an early use of asphalt in France. A pamphlet dated 1621, by "a certain Monsieur d'Eyrinys, states that he had discovered the existence (of asphaltum) in large quantities in the vicinity of Neufchatel", and that he proposed to use it in a variety of ways – "principally in the construction of air-proof granaries, and in protecting, by means of the arches, the water-courses in the city of Paris from the intrusion of dirt and filth", which at that time made the water unusable. "He expatiates also on the excellence of this material for forming level and durable terraces" in palaces, "the notion of forming such terraces in the streets not one likely to cross the brain of a Parisian of that generation".But the substance was generally neglected in France until the revolution of 1830. In the 1830s there was a surge of interest, and asphalt became widely used "for pavements, flat roofs, and the lining of cisterns, and in England, some use of it had been made of it for similar purposes". Its rise in Europe was "a sudden phenomenon", after natural deposits were found "in France at Osbann (Bas-Rhin), the Parc (Ain) and the Puy-de-la-Poix (Puy-de-Dôme)", although it could also be made artificially. One of the earliest uses in France was the laying of about 24,000 square yards of Seyssel asphalt at the Place de la Concorde in 1835. === United Kingdom === Among the earlier uses of bitumen in the United Kingdom was for etching. William Salmon's Polygraphice (1673) provides a recipe for varnish used in etching, consisting of three ounces of virgin wax, two ounces of mastic, and one ounce of asphaltum. By the fifth edition in 1685, he had included more asphaltum recipes from other sources.The first British patent for the use of asphalt was "Cassell's patent asphalte or bitumen" in 1834. Then on 25 November 1837, Richard Tappin Claridge patented the use of Seyssel asphalt (patent #7849), for use in asphalte pavement, having seen it employed in France and Belgium when visiting with Frederick Walter Simms, who worked with him on the introduction of asphalt to Britain. Dr T. Lamb Phipson writes that his father, Samuel Ryland Phipson, a friend of Claridge, was also "instrumental in introducing the asphalte pavement (in 1836)". Indeed, mastic pavements had been previously employed at Vauxhall by a competitor of Claridge, but without success.Claridge obtained a patent in Scotland on 27 March 1838, and obtained a patent in Ireland on 23 April 1838. In 1851, extensions for the 1837 patent and for both 1838 patents were sought by the trustees of a company previously formed by Claridge. Claridge's Patent Asphalte Company—formed in 1838 for the purpose of introducing to Britain "Asphalte in its natural state from the mine at Pyrimont Seysell in France",—"laid one of the first asphalt pavements in Whitehall". Trials were made of the pavement in 1838 on the footway in Whitehall, the stable at Knightsbridge Barracks, "and subsequently on the space at the bottom of the steps leading from Waterloo Place to St. James Park". "The formation in 1838 of Claridge's Patent Asphalte Company (with a distinguished list of aristocratic patrons, and Marc and Isambard Brunel as, respectively, a trustee and consulting engineer), gave an enormous impetus to the development of a British asphalt industry". "By the end of 1838, at least two other companies, Robinson's and the Bastenne company, were in production", with asphalt being laid as paving at Brighton, Herne Bay, Canterbury, Kensington, the Strand, and a large floor area in Bunhill-row, while meantime Claridge's Whitehall paving "continue(d) in good order".In 1838, there was a flurry of entrepreneurial activity involving asphalt, which had uses beyond paving. For example, asphalt could also be used for flooring, damp proofing in buildings, and for waterproofing of various types of pools and baths, both of which were also proliferating in the 19th century. On the London stockmarket, there were various claims as to the exclusivity of asphalt quality from France, Germany and England. And numerous patents were granted in France, with similar numbers of patent applications being denied in England due to their similarity to each other. In England, "Claridge's was the type most used in the 1840s and 50s".In 1914, Claridge's Company entered into a joint venture to produce tar-bound macadam, with materials manufactured through a subsidiary company called Clarmac Roads Ltd. Two products resulted, namely Clarmac, and Clarphalte, with the former being manufactured by Clarmac Roads and the latter by Claridge's Patent Asphalte Co., although Clarmac was more widely used. However, the First World War ruined the Clarmac Company, which entered into liquidation in 1915. The failure of Clarmac Roads Ltd had a flow-on effect to Claridge's Company, which was itself compulsorily wound up, ceasing operations in 1917, having invested a substantial amount of funds into the new venture, both at the outset and in a subsequent attempt to save the Clarmac Company. === United States === The first use of bitumen in the New World was by indigenous peoples. On the west coast, as early as the 13th century, the Tongva, Luiseño and Chumash peoples collected the naturally occurring bitumen that seeped to the surface above underlying petroleum deposits. All three groups used the substance as an adhesive. It is found on many different artifacts of tools and ceremonial items. For example, it was used on rattles to adhere gourds or turtle shells to rattle handles. It was also used in decorations. Small round shell beads were often set in asphaltum to provide decorations. It was used as a sealant on baskets to make them watertight for carrying water, possibly poisoning those who drank the water. Asphalt was used also to seal the planks on ocean-going canoes. Asphalt was first used to pave streets in the 1870s. At first naturally occurring "bituminous rock" was used, such as at Ritchie Mines in Macfarlan in Ritchie County, West Virginia from 1852 to 1873. In 1876, asphalt-based paving was used to pave Pennsylvania Avenue in Washington DC, in time for the celebration of the national centennial. In the horse-drawn era, streets were unpaved and covered with dirt or gravel. However, that produced uneven wear, opened new hazards for pedestrians and made for dangerous potholes for bicycles and for motor vehicles. Manhattan alone had 130,000 horses in 1900, pulling streetcars, wagons, and carriages, and leaving their waste behind. They were not fast, and pedestrians could dodge and scramble their way across the crowded streets. Small towns continued to rely on dirt and gravel, but larger cities wanted much better streets. They looked to wood or granite blocks by the 1850s. In 1890, a third of Chicago's 2000 miles of streets were paved, chiefly with wooden blocks, which gave better traction than mud. Brick surfacing was a good compromise, but even better was asphalt paving, which was easy to install and to cut through to get at sewers. With London and Paris serving as models, Washington laid 400,000 square yards of asphalt paving by 1882; it became the model for Buffalo, Philadelphia and elsewhere. By the end of the century, American cities boasted 30 million square yards of asphalt paving, well ahead of brick. The streets became faster and more dangerous so electric traffic lights were installed. Electric trolleys (at 12 miles per hour) became the main transportation service for middle class shoppers and office workers until they bought automobiles after 1945 and commuted from more distant suburbs in privacy and comfort on asphalt highways. === Canada === Canada has the world's largest deposit of natural bitumen in the Athabasca oil sands, and Canadian First Nations along the Athabasca River had long used it to waterproof their canoes. In 1719, a Cree named Wa-Pa-Su brought a sample for trade to Henry Kelsey of the Hudson’s Bay Company, who was the first recorded European to see it. However, it wasn't until 1787 that fur trader and explorer Alexander MacKenzie saw the Athabasca oil sands and said, "At about 24 miles from the fork (of the Athabasca and Clearwater Rivers) are some bituminous fountains into which a pole of 20 feet long may be inserted without the least resistance."The value of the deposit was obvious from the start, but the means of extracting the bitumen was not. The nearest town, Fort McMurray, Alberta, was a small fur trading post, other markets were far away, and transportation costs were too high to ship the raw bituminous sand for paving. In 1915, Sidney Ells of the Federal Mines Branch experimented with separation techniques and used the product to pave 600 feet of road in Edmonton, Alberta. Other roads in Alberta were paved with material extracted from oil sands, but it was generally not economic. During the 1920s Dr. Karl A. Clark of the Alberta Research Council patented a hot water oil separation process and entrepreneur Robert C. Fitzsimmons built the Bitumount oil separation plant, which between 1925 and 1958 produced up to 300 barrels (50 m3) per day of bitumen using Dr. Clark's method. Most of the bitumen was used for waterproofing roofs, but other uses included fuels, lubrication oils, printers ink, medicines, rust- and acid-proof paints, fireproof roofing, street paving, patent leather, and fence post preservatives. Eventually Fitzsimmons ran out of money and the plant was taken over by the Alberta government. Today the Bitumount plant is a Provincial Historic Site. === Photography and art === Bitumen was used in early photographic technology. In 1826 or 1827, it was used by French scientist Joseph Nicéphore Niépce to make the oldest surviving photograph from nature. The bitumen was thinly coated onto a pewter plate which was then exposed in a camera. Exposure to light hardened the bitumen and made it insoluble, so that when it was subsequently rinsed with a solvent only the sufficiently light-struck areas remained. Many hours of exposure in the camera were required, making bitumen impractical for ordinary photography, but from the 1850s to the 1920s it was in common use as a photoresist in the production of printing plates for various photomechanical printing processes.Bitumen was the nemesis of many artists during the 19th century. Although widely used for a time, it ultimately proved unstable for use in oil painting, especially when mixed with the most common diluents, such as linseed oil, varnish and turpentine. Unless thoroughly diluted, bitumen never fully solidifies and will in time corrupt the other pigments with which it comes into contact. The use of bitumen as a glaze to set in shadow or mixed with other colors to render a darker tone resulted in the eventual deterioration of many paintings, for instance those of Delacroix. Perhaps the most famous example of the destructiveness of bitumen is Théodore Géricault's Raft of the Medusa (1818–1819), where his use of bitumen caused the brilliant colors to degenerate into dark greens and blacks and the paint and canvas to buckle. == Modern use == === Global use === The vast majority of refined asphalt is used in construction: primarily as a constituent of products used in paving and roofing applications. According to the requirements of the end use, asphalt is produced to specification. This is achieved either by refining or blending. It is estimated that the current world use of asphalt is approximately 102 million tonnes per year. Approximately 85% of all the asphalt produced is used as the binder in asphalt concrete for roads. It is also used in other paved areas such as airport runways, car parks and footways. Typically, the production of asphalt concrete involves mixing fine and coarse aggregates such as sand, gravel and crushed rock with asphalt, which acts as the binding agent. Other materials, such as recycled polymers (e.g., rubber tyres), may be added to the asphalt to modify its properties according to the application for which the asphalt is ultimately intended. A further 10% of global asphalt production is used in roofing applications, where its waterproofing qualities are invaluable. The remaining 5% of asphalt is used mainly for sealing and insulating purposes in a variety of building materials, such as pipe coatings, carpet tile backing and paint. Asphalt is applied in the construction and maintenance of many structures, systems, and components, such as the following: === Rolled asphalt concrete === The largest use of asphalt is for making asphalt concrete for road surfaces; this accounts for approximately 85% of the asphalt consumed in the United States. There are about 4,000 asphalt concrete mixing plants in the US, and a similar number in Europe.Asphalt concrete pavement mixes are typically composed of 5% asphalt cement and 95% aggregates (stone, sand, and gravel). Due to its highly viscous nature, asphalt cement must be heated so it can be mixed with the aggregates at the asphalt mixing facility. The temperature required varies depending upon characteristics of the asphalt and the aggregates, but warm-mix asphalt technologies allow producers to reduce the temperature required.The weight of an asphalt pavement depends upon the aggregate type, the asphalt, and the air void content. An average example in the United States is about 112 pounds per square yard, per inch of pavement thickness.When maintenance is performed on asphalt pavements, such as milling to remove a worn or damaged surface, the removed material can be returned to a facility for processing into new pavement mixtures. The asphalt in the removed material can be reactivated and put back to use in new pavement mixes. With some 95% of paved roads being constructed of or surfaced with asphalt, a substantial amount of asphalt pavement material is reclaimed each year. According to industry surveys conducted annually by the Federal Highway Administration and the National Asphalt Pavement Association, more than 99% of the asphalt removed each year from road surfaces during widening and resurfacing projects is reused as part of new pavements, roadbeds, shoulders and embankments.Asphalt concrete paving is widely used in airports around the world. Due to the sturdiness and ability to be repaired quickly, it is widely used for runways. === Mastic asphalt === Mastic asphalt is a type of asphalt that differs from dense graded asphalt (asphalt concrete) in that it has a higher asphalt (binder) content, usually around 7–10% of the whole aggregate mix, as opposed to rolled asphalt concrete, which has only around 5% asphalt. This thermoplastic substance is widely used in the building industry for waterproofing flat roofs and tanking underground. Mastic asphalt is heated to a temperature of 210 °C (410 °F) and is spread in layers to form an impervious barrier about 20 millimeters (0.8 inches) thick. === Asphalt emulsion === A number of technologies allow asphalt to be mixed at much lower temperatures. These involve mixing with petroleum solvents to form "cutbacks" with reduced melting point or mixing with water to turn the asphalt into an emulsion. Asphalt emulsions contain up to 70% asphalt and typically less than 1.5% chemical additives. There are two main types of emulsions with different affinity for aggregates, cationic and anionic. Asphalt emulsions are used in a wide variety of applications. Chipseal involves spraying the road surface with asphalt emulsion followed by a layer of crushed rock, gravel or crushed slag. Slurry seal involves the creation of a mixture of asphalt emulsion and fine crushed aggregate that is spread on the surface of a road. Cold-mixed asphalt can also be made from asphalt emulsion to create pavements similar to hot-mixed asphalt, several inches in depth, and asphalt emulsions are also blended into recycled hot-mix asphalt to create low-cost pavements. === Synthetic crude oil === Synthetic crude oil, also known as syncrude, is the output from a bitumen upgrader facility used in connection with oil sand production in Canada. Bituminous sands are mined using enormous (100 ton capacity) power shovels and loaded into even larger (400 ton capacity) dump trucks for movement to an upgrading facility. The process used to extract the bitumen from the sand is a hot water process originally developed by Dr. Karl Clark of the University of Alberta during the 1920s. After extraction from the sand, the bitumen is fed into a bitumen upgrader which converts it into a light crude oil equivalent. This synthetic substance is fluid enough to be transferred through conventional oil pipelines and can be fed into conventional oil refineries without any further treatment. By 2015 Canadian bitumen upgraders were producing over 1 million barrels (160×10^3 m3) per day of synthetic crude oil, of which 75% was exported to oil refineries in the United States.In Alberta, five bitumen upgraders produce synthetic crude oil and a variety of other products: The Suncor Energy upgrader near Fort McMurray, Alberta produces synthetic crude oil plus diesel fuel; the Syncrude Canada, Canadian Natural Resources, and Nexen upgraders near Fort McMurray produce synthetic crude oil; and the Shell Scotford Upgrader near Edmonton produces synthetic crude oil plus an intermediate feedstock for the nearby Shell Oil Refinery. A sixth upgrader, under construction in 2015 near Redwater, Alberta, will upgrade half of its crude bitumen directly to diesel fuel, with the remainder of the output being sold as feedstock to nearby oil refineries and petrochemical plants. === Non-upgraded crude bitumen === Canadian bitumen does not differ substantially from oils such as Venezuelan extra-heavy and Mexican heavy oil in chemical composition, and the real difficulty is moving the extremely viscous bitumen through oil pipelines to the refinery. Many modern oil refineries are extremely sophisticated and can process non-upgraded bitumen directly into products such as gasoline, diesel fuel, and refined asphalt without any preprocessing. This is particularly common in areas such as the US Gulf coast, where refineries were designed to process Venezuelan and Mexican oil, and in areas such as the US Midwest where refineries were rebuilt to process heavy oil as domestic light oil production declined. Given the choice, such heavy oil refineries usually prefer to buy bitumen rather than synthetic oil because the cost is lower, and in some cases because they prefer to produce more diesel fuel and less gasoline. By 2015 Canadian production and exports of non-upgraded bitumen exceeded that of synthetic crude oil at over 1.3 million barrels (210×10^3 m3) per day, of which about 65% was exported to the United States.Because of the difficulty of moving crude bitumen through pipelines, non-upgraded bitumen is usually diluted with natural-gas condensate in a form called dilbit or with synthetic crude oil, called synbit. However, to meet international competition, much non-upgraded bitumen is now sold as a blend of multiple grades of bitumen, conventional crude oil, synthetic crude oil, and condensate in a standardized benchmark product such as Western Canadian Select. This sour, heavy crude oil blend is designed to have uniform refining characteristics to compete with internationally marketed heavy oils such as Mexican Mayan or Arabian Dubai Crude. === Radioactive waste encapsulation matrix === Asphalt was used starting in the 1960s as an hydrophobic matrix aiming to encapsulate radioactive waste such as medium-activity salts (mainly soluble sodium nitrate and sodium sulfate) produced by the reprocessing of spent nuclear fuels or radioactive sludges from sedimentation ponds. Bituminised radioactive waste containing highly radiotoxic alpha-emitting transuranic elements from nuclear reprocessing plants have been produced at industrial scale in France, Belgium and Japan, but this type of waste conditioning has been abandoned because operational safety issues (risks of fire, as occurred in a bituminisation plant at Tokai Works in Japan) and long-term stability problems related to their geological disposal in deep rock formations. One of the main problem is the swelling of asphalt exposed to radiation and to water. Asphalt swelling is first induced by radiation because of the presence of hydrogen gas bubbles generated by alpha and gamma radiolysis. A second mechanism is the matrix swelling when the encapsulated hygroscopic salts exposed to water or moisture start to rehydrate and to dissolve. The high concentration of salt in the pore solution inside the bituminised matrix is then responsible for osmotic effects inside the bituminised matrix. The water moves in the direction of the concentrated salts, the asphalt acting as a semi-permeable membrane. This also causes the matrix to swell. The swelling pressure due to osmotic effect under constant volume can be as high as 200 bar. If not properly managed, this high pressure can cause fractures in the near field of a disposal gallery of bituminised medium-level waste. When the bituminised matrix has been altered by swelling, encapsulated radionuclides are easily leached by the contact of ground water and released in the geosphere. The high ionic strength of the concentrated saline solution also favours the migration of radionuclides in clay host rocks. The presence of chemically reactive nitrate can also affect the redox conditions prevailing in the host rock by establishing oxidizing conditions, preventing the reduction of redox-sensitive radionuclides. Under their higher valences, radionuclides of elements such as selenium, technetium, uranium, neptunium and plutonium have a higher solubility and are also often present in water as non-retarded anions. This makes the disposal of medium-level bituminised waste very challenging. Different type of asphalt have been used: blown bitumen (partly oxidized with air oxygen at high temperature after distillation, and harder) and direct distillation bitumen (softer). Blown bitumens like Mexphalte, with a high content of saturated hydrocarbons, are more easily biodegraded by microorganisms than direct distillation bitumen, with a low content of saturated hydrocarbons and a high content of aromatic hydrocarbons.Concrete encapsulation of radwaste is presently considered a safer alternative by the nuclear industry and the waste management organisations. === Other uses === Roofing shingles account for most of the remaining asphalt consumption. Other uses include cattle sprays, fence-post treatments, and waterproofing for fabrics. Asphalt is used to make Japan black, a lacquer known especially for its use on iron and steel, and it is also used in paint and marker inks by some exterior paint supply companies to increase the weather resistance and permanence of the paint or ink, and to make the color darker. Asphalt is also used to seal some alkaline batteries during the manufacturing process. == Production == About 40,000,000 tons were produced in 1984. It is obtained as the "heavy" (i.e., difficult to distill) fraction. Material with a boiling point greater than around 500 °C is considered asphalt. Vacuum distillation separates it from the other components in crude oil (such as naphtha, gasoline and diesel). The resulting material is typically further treated to extract small but valuable amounts of lubricants and to adjust the properties of the material to suit applications. In a de-asphalting unit, the crude asphalt is treated with either propane or butane in a supercritical phase to extract the lighter molecules, which are then separated. Further processing is possible by "blowing" the product: namely reacting it with oxygen. This step makes the product harder and more viscous.Asphalt is typically stored and transported at temperatures around 150 °C (302 °F). Sometimes diesel oil or kerosene are mixed in before shipping to retain liquidity; upon delivery, these lighter materials are separated out of the mixture. This mixture is often called "bitumen feedstock", or BFS. Some dump trucks route the hot engine exhaust through pipes in the dump body to keep the material warm. The backs of tippers carrying asphalt, as well as some handling equipment, are also commonly sprayed with a releasing agent before filling to aid release. Diesel oil is no longer used as a release agent due to environmental concerns. === Oil sands === Naturally occurring crude bitumen impregnated in sedimentary rock is the prime feed stock for petroleum production from "oil sands", currently under development in Alberta, Canada. Canada has most of the world's supply of natural bitumen, covering 140,000 square kilometres (an area larger than England), giving it the second-largest proven oil reserves in the world. The Athabasca oil sands are the largest bitumen deposit in Canada and the only one accessible to surface mining, although recent technological breakthroughs have resulted in deeper deposits becoming producible by in situ methods. Because of oil price increases after 2003, producing bitumen became highly profitable, but as a result of the decline after 2014 it became uneconomic to build new plants again. By 2014, Canadian crude bitumen production averaged about 2.3 million barrels (370,000 m3) per day and was projected to rise to 4.4 million barrels (700,000 m3) per day by 2020. The total amount of crude bitumen in Alberta that could be extracted is estimated to be about 310 billion barrels (50×10^9 m3), which at a rate of 4,400,000 barrels per day (700,000 m3/d) would last about 200 years. === Alternatives and bioasphalt === Although uncompetitive economically, asphalt can be made from nonpetroleum-based renewable resources such as sugar, molasses and rice, corn and potato starches. Asphalt can also be made from waste material by fractional distillation of used motor oil, which is sometimes otherwise disposed of by burning or dumping into landfills. Use of motor oil may cause premature cracking in colder climates, resulting in roads that need to be repaved more frequently.Nonpetroleum-based asphalt binders can be made light-colored. Lighter-colored roads absorb less heat from solar radiation, reducing their contribution to the urban heat island effect. Parking lots that use asphalt alternatives are called green parking lots. === Albanian deposits === Selenizza is a naturally occurring solid hydrocarbon bitumen found in native deposits in Selenice, in Albania, the only European asphalt mine still in use. The bitumen is found in the form of veins, filling cracks in a more or less horizontal direction. The bitumen content varies from 83% to 92% (soluble in carbon disulphide), with a penetration value near to zero and a softening point (ring and ball) around 120 °C. The insoluble matter, consisting mainly of silica ore, ranges from 8% to 17%. Albanian bitumen extraction has a long history and was practiced in an organized way by the Romans. After centuries of silence, the first mentions of Albanian bitumen appeared only in 1868, when the Frenchman Coquand published the first geological description of the deposits of Albanian bitumen. In 1875, the exploitation rights were granted to the Ottoman government and in 1912, they were transferred to the Italian company Simsa. Since 1945, the mine was exploited by the Albanian government and from 2001 to date, the management passed to a French company, which organized the mining process for the manufacture of the natural bitumen on an industrial scale.Today the mine is predominantly exploited in an open pit quarry but several of the many underground mines (deep and extending over several km) still remain viable. Selenizza is produced primarily in granular form, after melting the bitumen pieces selected in the mine. Selenizza is mainly used as an additive in the road construction sector. It is mixed with traditional asphalt to improve both the viscoelastic properties and the resistance to ageing. It may be blended with the hot asphalt in tanks, but its granular form allows it to be fed in the mixer or in the recycling ring of normal asphalt plants. Other typical applications include the production of mastic asphalts for sidewalks, bridges, car-parks and urban roads as well as drilling fluid additives for the oil and gas industry. Selenizza is available in powder or in granular material of various particle sizes and is packaged in sacks or in thermal fusible polyethylene bags. A life-cycle assessment study of the natural selenizza compared with petroleum asphalt has shown that the environmental impact of the selenizza is about half the impact of the road asphalt produced in oil refineries in terms of carbon dioxide emission. == Economics == Although asphalt typically makes up only 4 to 5 percent (by weight) of the pavement mixture, as the pavement’s binder, it is also the most expensive part of the cost of the road-paving material.During asphalt's early use in modern paving, oil refiners gave it away. However, asphalt is, today, a highly traded commodity. Its prices increased substantially in the early 21st Century. A U.S. government report states: "In 2002, asphalt sold for approximately $160 per ton. By the end of 2006, the cost had doubled to approximately $320 per ton, and then it almost doubled again in 2012 to approximately $610 per ton."The report indicates that an "average" 1-mile (1.6-kilometer)-long, four-lane highway would include "300 tons of asphalt," which, "in 2002 would have cost around $48,000. By 2006 this would have increased to $96,000 and by 2012 to $183,000... an increase of about $135,000 for every mile of highway in just 10 years."Although asphalt typically makes up only 4 to 5 percent (by weight) of the pavement mixture, as the pavement’s binder, it is also the most expensive part of the cost of the road-paving material. The weight of an asphalt pavement depends upon the aggregate type, the asphalt, and the air void content. An average example in the United States is about 112 pounds per square yard, per inch of pavement thickness. == Health and safety == People can be exposed to asphalt in the workplace by breathing in fumes or skin absorption. The National Institute for Occupational Safety and Health (NIOSH) has set a recommended exposure limit of 5 mg/m3 over a 15-minute period. Asphalt is basically an inert material that must be heated or diluted to a point where it becomes workable for the production of materials for paving, roofing, and other applications. In examining the potential health hazards associated with asphalt, the International Agency for Research on Cancer (IARC) determined that it is the application parameters, predominantly temperature, that affect occupational exposure and the potential bioavailable carcinogenic hazard/risk of the asphalt emissions. In particular, temperatures greater than 199 °C (390 °F), were shown to produce a greater exposure risk than when asphalt was heated to lower temperatures, such as those typically used in asphalt pavement mix production and placement. IARC has classified asphalt as a Class 2B possible carcinogen. == See also == == Notes == == References == == Sources == Barth, Edwin J., Asphalt: Science and Technology Gordon and Breach (1962).

### Instruction: retrieve labels for this: The American National Standards Institute (ANSI, AN-see) is a private non-profit organization that oversees the development of voluntary consensus standards for products, services, processes, systems, and personnel in the United States. The organization also coordinates U.S. standards with international standards so that American products can be used worldwide. ANSI accredits standards that are developed by representatives of other standards organizations, government agencies, consumer groups, companies, and others. These standards ensure that the characteristics and performance of products are consistent, that people use the same definitions and terms, and that products are tested the same way. ANSI also accredits organizations that carry out product or personnel certification in accordance with requirements defined in international standards.The organization's headquarters are in Washington, D.C. ANSI's operations office is located in New York City. The ANSI annual operating budget is funded by the sale of publications, membership dues and fees, accreditation services, fee-based programs, and international standards programs. == History == ANSI was originally formed in 1918, when five engineering societies and three government agencies founded the American Engineering Standards Committee (AESC). In 1928, the AESC became the American Standards Association (ASA). In 1966, the ASA was reorganized and became United States of America Standards Institute (USASI). The present name was adopted in 1969. Prior to 1918, these five founding engineering societies: American Institute of Electrical Engineers (AIEE, now IEEE) American Society of Mechanical Engineers (ASME) American Society of Civil Engineers (ASCE) American Institute of Mining Engineers (AIME, now American Institute of Mining, Metallurgical, and Petroleum Engineers) American Society for Testing and Materials (now ASTM International)had been members of the United Engineering Society (UES). At the behest of the AIEE, they invited the U.S. government Departments of War, Navy (combined in 1947 to become the Department of Defense or DOD) and Commerce to join in founding a national standards organization. According to Adam Stanton, the first permanent secretary and head of staff in 1919, AESC started as an ambitious program and little else. Staff for the first year consisted of one executive, Clifford B. LePage, who was on loan from a founding member, ASME. An annual budget of $7,500 was provided by the founding bodies. In 1931, the organization (renamed ASA in 1928) became affiliated with the U.S. National Committee of the International Electrotechnical Commission (IEC), which had been formed in 1904 to develop electrical and electronics standards. == Members == ANSI's members are government agencies, organizations, academic and international bodies, and individuals. In total, the Institute represents the interests of more than 270,000 companies and organizations and 30 million professionals worldwide. == Process == Though ANSI itself does not develop standards, the Institute oversees the development and use of standards by accrediting the procedures of standards developing organizations. ANSI accreditation signifies that the procedures used by standards developing organizations meet the Institute's requirements for openness, balance, consensus, and due process. ANSI also designates specific standards as American National Standards, or ANS, when the Institute determines that the standards were developed in an environment that is equitable, accessible and responsive to the requirements of various stakeholders.Voluntary consensus standards quicken the market acceptance of products while making clear how to improve the safety of those products for the protection of consumers. There are approximately 9,500 American National Standards that carry the ANSI designation. The American National Standards process involves: consensus by a group that is open to representatives from all interested parties broad-based public review and comment on draft standards consideration of and response to comments incorporation of submitted changes that meet the same consensus requirements into a draft standard availability of an appeal by any participant alleging that these principles were not respected during the standards-development process. == International activities == In addition to facilitating the formation of standards in the United States, ANSI promotes the use of U.S. standards internationally, advocates U.S. policy and technical positions in international and regional standards organizations, and encourages the adoption of international standards as national standards where appropriate. The Institute is the official U.S. representative to the two major international standards organizations, the International Organization for Standardization (ISO), as a founding member, and the International Electrotechnical Commission (IEC), via the U.S. National Committee (USNC). ANSI participates in almost the entire technical program of both the ISO and the IEC, and administers many key committees and subgroups. In many instances, U.S. standards are taken forward to ISO and IEC, through ANSI or the USNC, where they are adopted in whole or in part as international standards. Adoption of ISO and IEC standards as American standards increased from 0.2% in 1986 to 15.5% in May 2012. === Standards panels === The Institute administers nine standards panels: ANSI Homeland Defense and Security Standardization Collaborative (HDSSC) ANSI Nanotechnology Standards Panel (ANSI-NSP) ID Theft Prevention and ID Management Standards Panel (IDSP) ANSI Energy Efficiency Standardization Coordination Collaborative (EESCC) Nuclear Energy Standards Coordination Collaborative (NESCC) Electric Vehicles Standards Panel (EVSP) ANSI-NAM Network on Chemical Regulation ANSI Biofuels Standards Coordination Panel Healthcare Information Technology Standards Panel (HITSP)Each of the panels works to identify, coordinate, and harmonize voluntary standards relevant to these areas. In 2009, ANSI and the National Institute of Standards and Technology (NIST) formed the Nuclear Energy Standards Coordination Collaborative (NESCC). NESCC is a joint initiative to identify and respond to the current need for standards in the nuclear industry. === American national standards === The ASA (as for American Standards Association) photographic exposure system, originally defined in ASA Z38.2.1 (since 1943) and ASA PH2.5 (since 1954), together with the DIN system (DIN 4512 since 1934), became the basis for the ISO system (since 1974), currently used worldwide (ISO 6, ISO 2240, ISO 5800, ISO 12232). A standard for the set of values used to represent characters in digital computers. The ANSI code standard extended the previously created ASCII seven bit code standard (ASA X3.4-1963), with additional codes for European alphabets (see also Extended Binary Coded Decimal Interchange Code or EBCDIC). In Microsoft Windows, the phrase "ANSI" refers to the Windows ANSI code pages (even though they are not ANSI standards). Most of these are fixed width, though some characters for ideographic languages are variable width. Since these characters are based on a draft of the ISO-8859 series, some of Microsoft's symbols are visually very similar to the ISO symbols, leading many to falsely assume that they are identical. The first computer programming language standard was "American Standard Fortran" (informally known as "FORTRAN 66"), approved in March 1966 and published as ASA X3.9-1966. The programming language COBOL had ANSI standards in 1968, 1974, and 1985. The COBOL 2002 standard was issued by ISO. The original standard implementation of the C programming language was standardized as ANSI X3.159-1989, becoming the well-known ANSI C. A popular Unified Thread Standard for nuts and bolts is ANSI/ASME B1.1 which was defined in 1935, 1949, 1989, and 2003. The ANSI-NSF International standards used for commercial kitchens, such as restaurants, cafeterias, delis, etc. The ANSI/APSP (Association of Pool & Spa Professionals) standards used for pools, spas, hot tubs, barriers, and suction entrapment avoidance. The ANSI/HI (Hydraulic Institute) standards used for pumps. The ANSI for eye protection is Z87.1, which gives a specific impact resistance rating to the eyewear. This standard is commonly used for shop glasses, shooting glasses, and many other examples of protective eyewear. The ANSI paper sizes (ANSI/ASME Y14.1). === Other initiatives === In 2008 ANSI, in partnership with Citation Technologies, created the first dynamic, online web library for ISO 14000 standards. On June 23, 2009, ANSI announced a product and services agreement with Citation Technologies to deliver all ISO Standards on a web-based platform. Through the ANSI-Citation partnership, 17,765 International Standards developed by more than 3,000 ISO technical bodies will be made available on the citation platform, arming subscribers with powerful search tools and collaboration, notification, and change-management functionality. ANSI, in partnership with Citation Technologies, AAMI, ASTM, and DIN, created a single, centralized database for medical device standards on September 9, 2009. In early 2009, ANSI launched a new Certificate Accreditation Program (ANSI-CAP) to provide neutral, third-party attestation that a given certificate program meets the American National Standard ASTM E2659-09. In 2009, ANSI began accepting applications for certification bodies seeking accreditation according to requirements defined under the Toy Safety Certification Program (TSCP) as the official third-party accreditor of TSCP’s product certification bodies. In 2006, ANSI launched www.StandardsPortal.org, an online resource for facilitating more open and efficient trade between international markets in the areas of standards, conformity assessment, and technical regulations. The site currently features content for China, India, and Korea, with additional countries and regions planned for future content. ANSI design standards have also been incorporated into building codes encompassing several specific building sub-sets, such as the ANSI/SPRI ES-1, which pertains to "Wind Design Standard for Edge Systems Used With Low Slope Roofing Systems", for example. == See also == == References == == External links == Official website ### Answer: <1918 establishments in the United States>, <501(c)(3) nonprofit organizations>, <ANSI standards>, <ISO member bodies>, <Organizations established in 1918>, <Standards organizations>, <Technical specifications>

### Instruction: retrieve labels for this: Apollo 11 was the spaceflight that landed the first two people on the Moon. Mission commander Neil Armstrong and pilot Buzz Aldrin, both American, landed the lunar module Eagle on July 20, 1969, at 20:17 UTC. Armstrong became the first person to step onto the lunar surface six hours after landing on July 21 at 02:56:15 UTC; Aldrin joined him about 20 minutes later. They spent about two and a quarter hours together outside the spacecraft, and collected 47.5 pounds (21.5 kg) of lunar material to bring back to Earth. Michael Collins piloted the command module Columbia alone in lunar orbit while they were on the Moon's surface. Armstrong and Aldrin spent 21.5 hours on the lunar surface before rejoining Columbia in lunar orbit. Apollo 11 was launched by a Saturn V rocket from Kennedy Space Center on Merritt Island, Florida, on July 16 at 9:32 am EDT (13:32 UTC) and was the fifth manned mission of NASA's Apollo program. The Apollo spacecraft had three parts: a command module (CM) with a cabin for the three astronauts, and the only part that returned to Earth; a service module (SM), which supported the command module with propulsion, electrical power, oxygen, and water; and a lunar module (LM) that had two stages – a descent stage for landing on the Moon, and an ascent stage to place the astronauts back into lunar orbit. After being sent to the Moon by the Saturn V's third stage, the astronauts separated the spacecraft from it and traveled for three days until they entered into lunar orbit. Armstrong and Aldrin then moved into the lunar module Eagle and landed in the Sea of Tranquility. The astronauts used Eagle's upper stage to lift off from the lunar surface and rejoin Collins in the command module. They jettisoned Eagle before they performed the maneuvers that blasted them out of lunar orbit on a trajectory back to Earth. They returned to Earth and splashed down in the Pacific Ocean on July 24 after more than eight days in space. The landing was broadcast on live TV to a worldwide audience. Armstrong stepped onto the lunar surface and described the event as "one small step for [a] man, one giant leap for mankind." Apollo 11 effectively ended the Space Race and fulfilled a national goal proposed in 1961 by U.S. President John F. Kennedy: "before this decade is out, of landing a man on the Moon and returning him safely to the Earth." == Framework == === Crew === The crew assignment of Neil Armstrong as Commander, Jim Lovell as Command Module Pilot (CMP) and Buzz Aldrin as Lunar Module Pilot (LMP) was officially announced on November 20, 1967. Apollo 11 was the second all-veteran multi-person crew on an American mission, the first being that of Apollo 10. An all-veteran crew would not be flown again until STS-26 in 1988. Lovell and Aldrin had previously flown together as the crew of Gemini 12. The crew was initially assigned as the backup for Apollo 9. Due to design and manufacturing delays in the Lunar Module (LM), Apollo 8 and Apollo 9 swapped prime and backup crews, and Armstrong's crew became the backup for Apollo 8. Based on the normal crew rotation scheme, Armstrong was then expected to command Apollo 11. There would be one change. Mike Collins on the Apollo 8 crew began experiencing trouble with his legs. Doctors diagnosed the problem as a bony growth between his fifth and sixth vertebrae, requiring surgery. Lovell took his place on the Apollo 8 crew, and, when he recovered, Collins joined Armstrong's crew as CMP. In the meantime, Fred Haise filled in as backup LMP, and Aldrin as backup CMP for Apollo 8. === Backup crew === The backup crew consisted of Lovell as Commander, William Anders as CMP, and Haise as LMP. Anders had flown with Lovell on Apollo 8. In early 1969, he accepted a job with the National Space Council effective August 1969 and announced that he would retire as an astronaut on that date. At that point Ken Mattingly was moved from the support crew into parallel training with Anders as backup CMP in case Apollo 11 was delayed past its intended July launch, at which point Anders would be unavailable. Lovell, Haise, and Mattingly would ultimately be assigned as the prime crew of Apollo 13. === Support crew === Charlie Duke, Capsule Communicator (CAPCOM) Ronald Evans (CAPCOM) Owen K. Garriott (CAPCOM) Don L. Lind (CAPCOM) Ken Mattingly (CAPCOM) Bruce McCandless II (CAPCOM) Harrison Schmitt (CAPCOM) Bill Pogue Jack Swigert William Carpentier (SURGEON) === Flight directors === Clifford E. Charlesworth (Green Team), launch and EVA Gerald D. Griffin (Gold Team) Gene Kranz (White Team), lunar landing Glynn Lunney (Black Team), lunar ascent === Call signs === After the crew of Apollo 10 named their spacecraft Charlie Brown and Snoopy, assistant manager for public affairs Julian Scheer wrote to Manned Spacecraft Center director George M. Low to suggest the Apollo 11 crew be less flippant in naming their craft. During early mission planning, the names Snowcone and Haystack were used and put in the news release.The Command Module was named Columbia after the Columbiad, the giant cannon shell "spacecraft" fired by a giant cannon (also from Florida) in Jules Verne's 1865 novel From the Earth to the Moon. It also referenced Columbia, a personification of the United States. The Lunar Module was named Eagle for the national bird of the United States, the bald eagle, which was featured prominently on the mission insignia. === Insignia === The Apollo 11 mission insignia was designed by Collins, who wanted a symbol for "peaceful lunar landing by the United States". At Lovell's suggestion, he chose an eagle as the symbol, put an olive branch in its beak, and drew a lunar background with the Earth in the distance. The sunlight in the image was coming from the wrong direction; the shadow should have been in the lower part of the Earth instead of the left. NASA officials felt that the talons of the eagle looked too "warlike" and after some discussion, the olive branch was moved to the claws. Armstrong was concerned that "eleven" would not be understood by non-English speakers, so they went with "Apollo 11"; they decided not to put their names on the patch, so it would "be representative of everyone who had worked toward a lunar landing". All colors are natural, with blue and gold borders around the patch.When the Eisenhower dollar coin was released in 1971, the patch design provided the eagle for its reverse side. The design was also used for the smaller Susan B. Anthony dollar unveiled in 1979, ten years after the Apollo 11 mission. === Mementos === Neil Armstrong's personal preference kit carried a piece of wood from the Wright brothers' 1903 airplane's left propeller and a piece of fabric from its wing, along with a diamond-studded astronaut pin originally given to Deke Slayton by the widows of the Apollo 1 crew. This pin had been intended to be flown on Apollo 1 and given to Slayton after the mission but following the disastrous launch pad fire and subsequent funerals, the widows gave the pin to Slayton and Armstrong took it on Apollo 11. == Mission highlights == === Launch and flight to lunar orbit === In addition to many people crowding highways and beaches near the launch site, millions watched the event on television, with NASA Chief of Public Information Jack King providing commentary. President Richard M. Nixon viewed the proceedings from the Oval Office of the White House.A Saturn V launched Apollo 11 from Launch Pad 39A, part of the Launch Complex 39 site at the Kennedy Space Center on July 16, 1969, at 13:32:00 UTC (9:32:00 a.m. EDT local time). It entered Earth orbit, at an altitude of 100.4 nautical miles (185.9 km) by 98.9 nautical miles (183.2 km), twelve minutes later. After one and a half orbits, the S-IVB third-stage engine pushed the spacecraft onto its trajectory toward the Moon with the trans-lunar injection (TLI) burn at 16:22:13 UTC. About 30 minutes later, the transposition, docking, and extraction maneuver was performed: this involved separating the Apollo Command/Service Module (CSM) from the spent rocket stage, turning around, and docking with the Lunar Module still attached to the stage. After the Lunar Module was extracted, the combined spacecraft headed for the Moon, while the rocket stage flew on a trajectory past the Moon and into orbit around the Sun.On July 19 at 17:21:50 UTC, Apollo 11 passed behind the Moon and fired its service propulsion engine to enter lunar orbit. In the thirty orbits that followed, the crew saw passing views of their landing site in the southern Sea of Tranquility (Mare Tranquillitatis) about 12 miles (19 km) southwest of the crater Sabine D (0.67408N, 23.47297E). The landing site was selected in part because it had been characterized as relatively flat and smooth by the automated Ranger 8 and Surveyor 5 landers along with the Lunar Orbiter mapping spacecraft and unlikely to present major landing or extravehicular activity (EVA) challenges. === Lunar descent === On July 20, 1969, the Lunar Module Eagle separated from the Command Module Columbia. Collins, alone aboard Columbia, inspected Eagle as it pirouetted before him to ensure the craft was not damaged. As the descent began, Armstrong and Aldrin found that they were passing landmarks on the surface four seconds early and reported that they were "long"; they would land miles west of their target point. Five minutes into the descent burn, and 6,000 feet (1,800 m) above the surface of the Moon, the LM navigation and guidance computer distracted the crew with the first of several unexpected "1202" and "1201" program alarms. Inside Mission Control Center in Houston, Texas, computer engineer Jack Garman told guidance officer Steve Bales it was safe to continue the descent, and this was relayed to the crew. The program alarms indicated "executive overflows", meaning the guidance computer could not complete all of its tasks in real time and had to postpone some of them. Due to an error in the checklist manual, the rendezvous radar switch was placed in the wrong position. This caused it to send erroneous signals to the computer. The result was that the computer was being asked to perform all of its normal functions for landing while receiving an extra load of spurious data which used up 15% of its time. The computer (or rather the software in it) was smart enough to recognize that it was being asked to perform more tasks than it should be performing. It then sent out an alarm, which meant to the astronaut, I'm overloaded with more tasks than I should be doing at this time and I'm going to keep only the more important tasks; i.e., the ones needed for landing ... Actually, the computer was programmed to do more than recognize error conditions. A complete set of recovery programs was incorporated into the software. The software's action, in this case, was to eliminate lower priority tasks and re-establish the more important ones ... If the computer hadn't recognized this problem and taken recovery action, I doubt if Apollo 11 would have been the successful moon landing it was. === Landing === When Armstrong again looked outside, he saw that the computer's landing target was in a boulder-strewn area just north and east of a 300-meter (980 ft) diameter crater (later determined to be West crater, named for its location in the western part of the originally planned landing ellipse). Armstrong took semi-automatic control and, with Aldrin calling out altitude and velocity data, landed at 20:17:40 UTC on Sunday July 20 with about 25 seconds of fuel left.Apollo 11 landed with less fuel than other missions, and the astronauts encountered a premature low fuel warning. This was later found to be the result of greater propellant 'slosh' than expected, uncovering a fuel sensor. On subsequent missions, extra anti-slosh baffles were added to the tanks to prevent this.Throughout the descent, Aldrin had called out navigation data to Armstrong, who was busy piloting the LM. A few moments before the landing, a light informed Aldrin that at least one of the 67-inch (170 cm) probes hanging from Eagle's footpads had touched the surface, and he said: "Contact light!" Three seconds later, Eagle landed and Armstrong said "Shutdown." Aldrin immediately said "Okay, engine stop. ACA – out of detent." Armstrong acknowledged "Out of detent. Auto" and Aldrin continued "Mode control – both auto. Descent engine command override off. Engine arm – off. 413 is in." Charles Duke, CAPCOM during the landing phase, acknowledged their landing by saying "We copy you down, Eagle." Armstrong acknowledged Aldrin's completion of the post landing checklist with "Engine arm is off", before responding to Duke with the words, "Houston, Tranquility Base here. The Eagle has landed." Armstrong's unrehearsed change of call sign from "Eagle" to "Tranquility Base" emphasized to listeners that landing was complete and successful. Duke mispronounced his reply as he expressed the relief at Mission Control: "Roger, Twan— Tranquility, we copy you on the ground. You got a bunch of guys about to turn blue. We're breathing again. Thanks a lot."Two and a half hours after landing, before preparations began for the EVA, Aldrin radioed to Earth: This is the LM pilot. I'd like to take this opportunity to ask every person listening in, whoever and wherever they may be, to pause for a moment and contemplate the events of the past few hours and to give thanks in his or her own way. He then took communion privately. At this time NASA was still fighting a lawsuit brought by atheist Madalyn Murray O'Hair (who had objected to the Apollo 8 crew reading from the Book of Genesis) demanding that their astronauts refrain from broadcasting religious activities while in space. As such, Aldrin chose to refrain from directly mentioning taking communion on the Moon. Aldrin was an elder at the Webster Presbyterian Church, and his communion kit was prepared by the pastor of the church, the Rev. Dean Woodruff. Aldrin described communion on the Moon and the involvement of his church and pastor in the October 1970 edition of Guideposts magazine and in his book Return to Earth. Webster Presbyterian possesses the chalice used on the Moon and commemorates the event each year on the Sunday closest to July 20.The schedule for the mission called for the astronauts to follow the landing with a five-hour sleep period as they had been awake since early morning. However, they elected to forgo the sleep period and begin the preparations for the EVA early, thinking that they would be unable to sleep. === Lunar surface operations === The astronauts planned placement of the Early Apollo Scientific Experiment Package (EASEP) and the U.S. flag by studying their landing site through Eagle's twin triangular windows, which gave them a 60° field of view. Preparation required longer than the two hours scheduled. Armstrong initially had some difficulties squeezing through the hatch with his Portable Life Support System (PLSS). According to veteran Moon-walker John Young, a redesign of the LM to incorporate a smaller hatch had not been followed by a redesign of the PLSS backpack, so some of the highest heart rates recorded from Apollo astronauts occurred during LM egress and ingress.Several books indicate early mission timelines had Buzz Aldrin rather than Neil Armstrong as the first man on the Moon.At 02:39 UTC on Monday July 21, 1969, Armstrong opened the hatch, and at 02:51 UTC began his descent to the lunar surface. The Remote Control Unit controls on his chest kept him from seeing his feet. Climbing down the nine-rung ladder, Armstrong pulled a D-ring to deploy the Modular Equipment Stowage Assembly (MESA) folded against Eagle's side and activate the TV camera, and at 02:56:15 UTC he set his left foot on the surface. The first landing used slow-scan television incompatible with commercial TV, so it was displayed on a special monitor and a conventional TV camera viewed this monitor, significantly reducing the quality of the picture. The signal was received at Goldstone in the United States but with better fidelity by Honeysuckle Creek Tracking Station in Australia. Minutes later the feed was switched to the more sensitive Parkes radio telescope in Australia. Despite some technical and weather difficulties, ghostly black and white images of the first lunar EVA were received and broadcast to at least 600 million people on Earth. Although copies of this video in broadcast format were saved and are widely available, recordings of the original slow scan source transmission from the lunar surface were accidentally destroyed during routine magnetic tape re-use at NASA. While still on the ladder, Armstrong uncovered a plaque mounted on the LM descent stage bearing two drawings of Earth (of the Western and Eastern Hemispheres), an inscription, and signatures of the astronauts and President Nixon. The inscription read: Here men from the planet Earth first set foot upon the Moon, July 1969 A.D. We came in peace for all mankind. After describing the surface dust as "very fine-grained" and "almost like a powder," six and a half hours after landing, Armstrong stepped off Eagle's footpad and declared, "That's one small step for [a] man, one giant leap for mankind."Armstrong intended to say "That's one small step for a man", but the word "a" is not audible in the transmission, and thus was not initially reported by most observers of the live broadcast. When later asked about his quote, Armstrong said he believed he said "for a man", and subsequent printed versions of the quote included the "a" in square brackets. One explanation for the absence may be that his accent caused him to slur the words "for a" together; another is the intermittent nature of the audio and video links to Earth, partly because of storms near Parkes Observatory. More recent digital analysis of the tape claims to reveal the "a" may have been spoken but obscured by static. About seven minutes after stepping onto the Moon's surface, Armstrong collected a contingency soil sample using a sample bag on a stick. He then folded the bag and tucked it into a pocket on his right thigh. This was to guarantee there would be some lunar soil brought back in case an emergency required the astronauts to abandon the EVA and return to the LM.Twelve minutes after the contingency sample was collected, Aldrin joined Armstrong on the surface, and described the view with the simple phrase, "Magnificent desolation." In addition to fulfilling President Kennedy's mandate to land a man on the Moon before the end of the 1960s, Apollo 11 was an engineering test of the Apollo system; therefore, Armstrong snapped photos of the LM so engineers would be able to judge its post-landing condition. He removed the TV camera from the MESA and made a panoramic sweep, then mounted it on a tripod 68 feet (21 m) from the LM. The TV camera cable remained partly coiled and presented a tripping hazard throughout the EVA. Armstrong said that moving in the lunar gravity, one-sixth of Earth's, was "even perhaps easier than the simulations ... It's absolutely no trouble to walk around." Aldrin joined him on the surface and tested methods for moving around, including two-footed kangaroo hops. The PLSS backpack created a tendency to tip backward, but neither astronaut had serious problems maintaining balance. Loping became the preferred method of movement. The astronauts reported that they needed to plan their movements six or seven steps ahead. The fine soil was quite slippery. Aldrin remarked that moving from sunlight into Eagle's shadow produced no temperature change inside the suit, though the helmet was warmer in sunlight, so he felt cooler in shadow.The astronauts planted a specially designed U.S. flag on the lunar surface, in clear view of the TV camera. Sometime later, President Richard Nixon spoke to them through a telephone-radio transmission which Nixon called "the most historic phone call ever made from the White House." Nixon originally had a long speech prepared to read during the phone call, but Frank Borman, who was at the White House as a NASA liaison during Apollo 11, convinced Nixon to keep his words brief, to respect the lunar landing as Kennedy's legacy. Armstrong thanked the President, and gave a brief reflection on the significance of the moment: Nixon: Hello, Neil and Buzz. I'm talking to you by telephone from the Oval Room at the White House. And this certainly has to be the most historic telephone call ever made. I just can't tell you how proud we all are of what you've done. For every American, this has to be the proudest day of our lives. And for people all over the world, I am sure they too join with Americans in recognizing what an immense feat this is. Because of what you have done, the heavens have become a part of man's world. And as you talk to us from the Sea of Tranquility, it inspires us to redouble our efforts to bring peace and tranquility to Earth. For one priceless moment in the whole history of man, all the people on this Earth are truly one: one in their pride in what you have done, and one in our prayers that you will return safely to Earth. Armstrong: Thank you, Mr. President. It's a great honor and privilege for us to be here, representing not only the United States, but men of peace of all nations, and with interest and curiosity, and men with a vision for the future. It's an honor for us to be able to participate here today. The MESA failed to provide a stable work platform and was in shadow, slowing work somewhat. As they worked, the moonwalkers kicked up gray dust which soiled the outer part of their suits, the integrated thermal meteoroid garment. They deployed the EASEP, which included a passive seismograph and a Lunar Ranging Retroreflector (LRRR). Then Armstrong walked 196 feet (60 m) from the LM to snap photos at the rim of Little West Crater while Aldrin collected two core tubes. He used the geological hammer to pound in the tubes – the only time the hammer was used on Apollo 11. The astronauts then collected rock samples using scoops and tongs on extension handles. Many of the surface activities took longer than expected, so they had to stop documenting sample collection halfway through the allotted 34 minutes. Three new minerals were discovered in the rock samples collected by the astronauts: armalcolite, tranquillityite, and pyroxferroite. Armalcolite was named after Armstrong, Aldrin, and Collins. During this period, Mission Control used a coded phrase to warn Armstrong that his metabolic rates were high and that he should slow down. He was moving rapidly from task to task as time ran out. However, as metabolic rates remained generally lower than expected for both astronauts throughout the walk, Mission Control granted the astronauts a 15-minute extension. In a 2010 interview, Armstrong, who had walked a maximum of 196 feet (60 m) from the LM, explained that NASA limited the first moonwalk's time and distance because there was no empirical proof of how much cooling water the astronauts' PLSS backpacks would consume to handle their body heat generation while working on the Moon. === Lunar ascent and return === Aldrin entered Eagle first. With some difficulty the astronauts lifted film and two sample boxes containing 21.55 kilograms (47.5 lb) of lunar surface material to the LM hatch using a flat cable pulley device called the Lunar Equipment Conveyor. Armstrong reminded Aldrin of a bag of memorial items in his suit pocket sleeve, and Aldrin tossed the bag down; Armstrong then jumped to the ladder's third rung and climbed into the LM. After transferring to LM life support, the explorers lightened the ascent stage for the return to lunar orbit by tossing out their PLSS backpacks, lunar overshoes, one Hasselblad camera, and other equipment. They then pressurized the LM and settled down to sleep. President Nixon's speech writer William Safire had prepared In Event of Moon Disaster for the President to read on television in the event the Apollo 11 astronauts were stranded on the Moon. The contingency plan originated in a memo from Safire to Nixon's White House Chief of Staff H. R. Haldeman, in which Safire suggested a protocol the administration might follow in reaction to such a disaster. According to the plan, Mission Control would "close down communications" with the LM, and a clergyman would "commend their souls to the deepest of the deep" in a public ritual likened to burial at sea. The last line of the prepared text contained an allusion to Rupert Brooke's First World War poem, "The Soldier". The plan included presidential telephone calls to the astronauts' wives. While moving inside the cabin, Aldrin accidentally damaged the circuit breaker that would arm the main engine for lift off from the Moon. There was a concern this would prevent firing the engine, stranding them on the Moon. Fortunately, a felt-tip pen was sufficient to activate the switch. Had this not worked, the Lunar Module circuitry could have been reconfigured to allow firing the ascent engine. After about seven hours of rest, the crew was awakened by Houston to prepare for the return flight. Two and a half hours later, at 17:54 UTC, they lifted off in Eagle's ascent stage to rejoin Collins aboard Columbia in lunar orbit. After more than 21½ total hours on the lunar surface, they had left behind scientific instruments that included a retroreflector array used for the Lunar Laser Ranging Experiment and a Passive Seismic Experiment Package used to measure moonquakes. They also left an Apollo 1 mission patch, and a memorial bag containing a gold replica of an olive branch as a traditional symbol of peace and a silicon message disk. The disk carries the goodwill statements by Presidents Eisenhower, Kennedy, Johnson, and Nixon and messages from leaders of 73 countries around the world. The disc also carries a listing of the leadership of the US Congress, a listing of members of the four committees of the House and Senate responsible for the NASA legislation, and the names of NASA's past and present top management. (In his 1989 book, Men from Earth, Aldrin says that the items included Soviet medals commemorating Cosmonauts Vladimir Komarov and Yuri Gagarin.) Also, according to Deke Slayton's book Moonshot, Armstrong carried with him a special diamond-studded astronaut pin from Slayton. Film taken from the LM Ascent Stage upon liftoff from the Moon reveals the American flag, planted some 25 feet (8 m) from the descent stage, whipping violently in the exhaust of the ascent stage engine. Aldrin looked up in time to witness the flag topple: "The ascent stage of the LM separated ... I was concentrating on the computers, and Neil was studying the attitude indicator, but I looked up long enough to see the flag fall over." Subsequent Apollo missions usually planted the American flags at least 100 feet (30 m) from the LM to prevent them being blown over by the ascent engine exhaust. After rendezvous with Columbia, Eagle's ascent stage was jettisoned into lunar orbit on July 21, 1969, at 23:41 UTC. Just before the Apollo 12 flight, it was noted that Eagle was still likely to be orbiting the Moon. Later NASA reports mentioned that Eagle's orbit had decayed, resulting in it impacting in an "uncertain location" on the lunar surface. The location is uncertain because the Eagle ascent stage was not tracked after it was jettisoned, and the lunar gravity field is sufficiently non-uniform to make the orbit of the spacecraft unpredictable after a short time. NASA estimated that the orbit had decayed within months and would have impacted on the Moon. On July 23, the last night before splashdown, the three astronauts made a television broadcast in which Collins commented: ... The Saturn V rocket which put us in orbit is an incredibly complicated piece of machinery, every piece of which worked flawlessly ... We have always had confidence that this equipment will work properly. All this is possible only through the blood, sweat, and tears of a number of a people ... All you see is the three of us, but beneath the surface are thousands and thousands of others, and to all of those, I would like to say, "Thank you very much." Aldrin added: This has been far more than three men on a mission to the Moon; more, still, than the efforts of a government and industry team; more, even, than the efforts of one nation. We feel that this stands as a symbol of the insatiable curiosity of all mankind to explore the unknown ... Personally, in reflecting on the events of the past several days, a verse from Psalms comes to mind. "When I consider the heavens, the work of Thy fingers, the Moon and the stars, which Thou hast ordained; What is man that Thou art mindful of him?" Armstrong concluded: The responsibility for this flight lies first with history and with the giants of science who have preceded this effort; next with the American people, who have, through their will, indicated their desire; next with four administrations and their Congresses, for implementing that will; and then, with the agency and industry teams that built our spacecraft, the Saturn, the Columbia, the Eagle, and the little EMU, the spacesuit and backpack that was our small spacecraft out on the lunar surface. We would like to give special thanks to all those Americans who built the spacecraft; who did the construction, design, the tests, and put their hearts and all their abilities into those craft. To those people tonight, we give a special thank you, and to all the other people that are listening and watching tonight, God bless you. Good night from Apollo 11. On the return to Earth, a bearing at the Guam tracking station failed, potentially preventing communication on the last segment of the Earth return. A regular repair was not possible in the available time but the station director, Charles Force, had his ten-year-old son Greg use his small hands to reach into the housing and pack it with grease. Greg later was thanked by Armstrong. === Splashdown and quarantine === On July 24, the astronauts returned home aboard the Command Module Columbia just before dawn local time (16:51 UTC) at 13°19′N 169°9′W, in the Pacific Ocean 2,660 km (1,440 nmi) east of Wake Island, 380 km (210 nmi) south of Johnston Atoll, and 24 km (13 nmi) from the recovery ship, USS Hornet. This is near the village of Vatia in American Samoa. The American Samoa-flag which was brought to the moon by Apollo 11 is on display at the Jean P. Haydon Museum in Pago Pago, the territorial capital of American Samoa.At 16:44 UTC the drogue parachutes had been deployed and seven minutes later the Command Module struck the water forcefully. During splashdown, the Command Module landed upside down but was righted within 10 minutes by flotation bags triggered by the astronauts. "Everything's okay. Our checklist is complete. Awaiting swimmers", was Armstrong's last official transmission from Columbia. A diver from the Navy helicopter hovering above attached a sea anchor to the Command Module to prevent it from drifting. Additional divers attached flotation collars to stabilize the module and position rafts for astronaut extraction. Though the chance of bringing back pathogens from the lunar surface was considered remote, it was considered a possibility and NASA took great precautions at the recovery site. Divers provided the astronauts with Biological Isolation Garments (BIGs) which were worn until they reached isolation facilities on board the Hornet. Additionally, astronauts were rubbed down with a sodium hypochlorite solution and the Command Module wiped with Betadine to remove any lunar dust that might be present. The raft containing decontamination materials was then intentionally sunk.A second Sea King helicopter - "Helicopter 66" - hoisted the astronauts aboard one by one, where a NASA flight surgeon gave each a brief physical check during the 0.5 nautical miles (930 m) trip back to the Hornet. After touchdown on the Hornet, the astronauts exited the helicopter, leaving the flight surgeon and three crewmen. The helicopter was then lowered into hangar bay #2 where the astronauts walked the 30 feet (9.1 m) to the Mobile Quarantine Facility (MQF) where they would begin the earth-based portion of their 21 days of quarantine. This practice would continue for two more Apollo missions, Apollo 12 and Apollo 14, before the Moon was proven to be barren of life and the quarantine process dropped.President Richard Nixon was aboard Hornet to personally welcome the astronauts back to Earth. He told the astronauts, "As a result of what you've done, the world has never been closer together before." After Nixon departed, the Hornet was brought alongside the five-ton Command Module where it was placed aboard by the ship's crane, placed on a dolly and moved next to the MQF. The Hornet sailed for Pearl Harbor where Columbia and the MQF were airlifted to the Manned Spacecraft Center.In accordance with the Extra-Terrestrial Exposure Law, a set of regulations promulgated by NASA on July 16 to codify its quarantine protocol, the astronauts continued in quarantine out of concern that the Moon might contain undiscovered pathogens and that the astronauts might have been exposed to them during their Moon walks. However, after three weeks in confinement (first in the Apollo spacecraft, then in their trailer on the Hornet, and finally in the Lunar Receiving Laboratory at the Manned Spacecraft Center), the astronauts were given a clean bill of health. On August 10, 1969, the Interagency Committee on Back Contamination met in Atlanta and lifted the quarantine on the astronauts, on those who had joined them in quarantine (NASA physician William Carpentier and MQF project engineer John Hirasaki), and on Columbia itself. Loose equipment from the spacecraft would remain in isolation until the lunar samples were released for study. === Celebration === On August 13, they rode in parades in their honor in New York, Chicago, and Los Angeles. On the same evening in Los Angeles there was an official State Dinner to celebrate the flight, attended by members of Congress, 44 governors, the Chief Justice of the United States, and ambassadors from 83 nations at the Century Plaza Hotel. President Richard Nixon and Vice President Spiro T. Agnew honored each astronaut with a presentation of the Presidential Medal of Freedom. This celebration was the beginning of a 45-day "Giant Leap" tour that brought the astronauts to 25 foreign countries and included visits with prominent leaders such as Queen Elizabeth II of the United Kingdom. Many nations honored the first manned Moon landing with special features in magazines or by issuing Apollo 11 commemorative postage stamps or coins.On September 16, 1969, the three astronauts spoke before a joint session of Congress on Capitol Hill. They presented two US flags, one to the House of Representatives and the other to the Senate, that had been carried to the surface of the Moon with them. === Moon race === The Soviet Union had been competing with the US in landing a man on the Moon but had been hampered by repeated failures in development of a launcher comparable to the Saturn V. Meanwhile, they tried to beat the US to return lunar material to the Earth by means of unmanned probes. On July 13, three days before Apollo 11's launch, they launched Luna 15, which reached lunar orbit before Apollo 11. During descent, a malfunction caused Luna 15 to crash in Mare Crisium about two hours before Armstrong and Aldrin took off from the Moon's surface to begin their voyage home. The Jodrell Bank Observatory radio telescope in England was later discovered to have recorded transmissions from Luna 15 during its descent, and this was published in July 2009 on the 40th anniversary of Apollo 11. == Legacy == === Spacecraft location === The Command Module Columbia was displayed at the National Air and Space Museum (NASM), Washington, D.C. It was in the central Milestones of Flight exhibition hall in front of the Jefferson Drive entrance, sharing the main hall with other pioneering flight vehicles such as the Wright Flyer, the Spirit of St. Louis, the Bell X-1, the North American X-15, Mercury spacecraft Friendship 7, and Gemini 4. Armstrong's and Aldrin's space suits are displayed in the museum's Apollo to the Moon exhibit. The quarantine trailer, the flotation collar, and the righting spheres are displayed at the Smithsonian's Steven F. Udvar-Hazy Center annex near Washington Dulles International Airport in Chantilly, Virginia. The descent stage of the Lunar Module Eagle remains on the Moon. In 2009, the Lunar Reconnaissance Orbiter (LRO) imaged the various Apollo landing sites on the surface of the Moon, for the first time with sufficient resolution to see the descent stages of the lunar modules, scientific instruments, and foot trails made by the astronauts. The remains of the ascent stage are presumed to lie at an unknown location on the lunar surface, after being abandoned and reimpacting the Moon. In March 2012 a team of specialists financed by Amazon founder Jeff Bezos located the F-1 engines that launched Apollo 11 into space. The engines were found below the Atlantic Ocean's surface through the use of advanced sonar scanning. His team brought parts of two of the five engines to the surface. In July 2013, a conservator discovered a serial number under the rust on one of the engines raised from the Atlantic, which NASA confirmed was from the Apollo 11 launch. Columbia was moved in 2017 to the NASM Mary Baker Engen Restoration Hangar at the Steven F. Udvar-Hazy Center in Chantilly, Virginia, to be readied for a four-city tour titled Destination Moon: The Apollo 11 Mission. This will include Space Center Houston (October 14, 2017 to March 18, 2018), the Saint Louis Science Center (April 14 to September 3, 2018), the Senator John Heinz History Center in Pittsburgh (September 29, 2018 to February 18, 2019), and the Seattle Museum of Flight (March 16 to September 2, 2019).The S-IVB stage which performed Apollo 11's trans-lunar injection remains in a solar orbit near to that of Earth. === 40th anniversary events === On July 15, 2009, Life.com released a photo gallery of previously unpublished photos of the astronauts taken by Life photographer Ralph Morse prior to the Apollo 11 launch. From July 16–24, 2009, NASA streamed the original mission audio on its website in real time 40 years to the minute after the events occurred. In addition, it is in the process of restoring the video footage and has released a preview of key moments. In July 2010, air-to-ground voice recordings and film footage shot in Mission Control during the Apollo 11 powered descent and landing was re-synchronised and released for the first time. The John F. Kennedy Presidential Library and Museum set up a Flash website that rebroadcasts the transmissions of Apollo 11 from launch to landing on the Moon.On July 20, 2009, the crew of Armstrong, Aldrin, and Collins met with U.S. President Barack Obama at the White House. "We expect that there is, as we speak, another generation of kids out there who are looking up at the sky and are going to be the next Armstrong, Collins, and Aldrin", Obama said. "We want to make sure that NASA is going to be there for them when they want to take their journey." On August 7, 2009, an act of Congress awarded the three astronauts a Congressional Gold Medal, the highest civilian award in the United States. The bill was sponsored by Florida Sen. Bill Nelson and Florida Rep. Alan Grayson.A group of British scientists interviewed as part of the anniversary events reflected on the significance of the Moon landing: It was carried out in a technically brilliant way with risks taken ... that would be inconceivable in the risk-averse world of today ... The Apollo programme is arguably the greatest technical achievement of mankind to date ... nothing since Apollo has come close [to] the excitement that was generated by those astronauts – Armstrong, Aldrin and the 10 others who followed them. == Gallery == == Notes == == References == This article incorporates public domain material from websites or documents of the National Aeronautics and Space Administration. == Bibliography == Brooks, Courtney G.; Grimwood, James M.; Swenson, Loyd S., Jr. (1979).

### Instruction: retrieve labels for this: Apollo 8, the second manned spaceflight mission in the United States Apollo space program, was launched on December 21, 1968, and became the first manned spacecraft to leave Earth orbit, reach the Earth's Moon, orbit it and return safely to Earth. The three-astronaut crew — Commander Frank Borman, Command Module Pilot James Lovell, and Lunar Module Pilot William Anders — became the first humans to: travel beyond low Earth orbit; see Earth as a whole planet; enter the gravity well of another celestial body (Earth's moon); orbit another celestial body (Earth's moon); directly see the far side of the Moon with their own eyes; witness an Earthrise; escape the gravity of another celestial body (Earth's moon); and re-enter the gravitational well of Earth. The 1968 mission, the third flight of the Saturn V rocket and that rocket's first crewed launch, was also the first human spaceflight launch from the Kennedy Space Center, Florida, located adjacent to Cape Canaveral Air Force Station. Originally planned as a second Lunar Module/Command Module test in an elliptical medium Earth orbit in early 1969, the mission profile was changed in August 1968 to a more ambitious Command Module-only lunar orbital flight to be flown in December, because the Lunar Module was not yet ready to make its first flight. This meant Borman's crew was scheduled to fly two to three months sooner than originally planned, leaving them a shorter time for training and preparation, thus placing more demands than usual on their time and discipline. Apollo 8 took 68 hours (2.8 days) to travel the distance to the Moon. It orbited ten times over the course of 20 hours, during which the crew made a Christmas Eve television broadcast where they read the first 10 verses from the Book of Genesis. At the time, the broadcast was the most watched TV program ever. Apollo 8's successful mission paved the way for Apollo 11 to fulfill U.S. President John F. Kennedy's goal of landing a man on the Moon before the end of the 1960s. The Apollo 8 astronauts returned to Earth on December 27, 1968, when their spacecraft splashed down in the Northern Pacific Ocean. The crew members were named Time magazine's "Men of the Year" for 1968 upon their return. == Crew == Lovell was originally the CMP on the back-up crew, with Michael Collins as the prime crew's CMP. However, Collins was replaced in July 1968, after suffering a cervical disc herniation that required surgery to repair.This crew was unique among pre-shuttle era missions in that the commander was not the most experienced member of the crew, as Lovell had flown twice before, on Gemini VII and Gemini XII. This was also the first case of the rarity of an astronaut who had commanded a spaceflight mission subsequently flying as a non-commander, as Lovell had previously commanded Gemini XII. === Backup crew === On a lunar mission, the Command Module Pilot (CMP) was assigned the role of navigator, while the Lunar Module Pilot (LMP) was assigned the role of flight engineer, responsible for monitoring all spacecraft systems, even if the flight didn't include a Lunar Module.Edwin "Buzz" Aldrin was originally the backup LMP. When Lovell was rotated to the prime crew, no one with experience on CSM-103 (the specific spacecraft used for the mission) was available, so Aldrin was moved to CMP and Fred Haise brought in as backup LMP. Neil Armstrong went on to command Apollo 11, where Aldrin was returned to the LMP position and Collins was assigned as CMP. Haise was rotated out of the crew and onto the backup crew of Apollo 11 as LMP. === Mission control === The Earth-based mission control teams for Apollo 8 consisted of astronauts assigned to the support crew, as well as non-astronaut flight directors and their staffs. The support crew members were not trained to fly the mission, but were able to stand in for astronauts in meetings and be involved in the minutiae of mission planning, while the prime and backup crews trained. They also served as CAPCOMs during the mission. For Apollo 8, these crew members included astronauts Michael Collins, John S. Bull, Vance D. Brand, Gerald P. Carr, and Ken Mattingly. The mission control teams on Earth rotated in three shifts, each led by a flight director. The directors for Apollo 8 included Clifford E. Charlesworth (Green team), Glynn Lunney (Black team), and Milton Windler (Maroon team). === Mission insignia === The triangular shape of the insignia symbolizes the shape of the Apollo Command Module (CM). It shows a red figure-8 looping around the Earth and Moon representing the mission number as well as the circumlunar nature of the mission. On the red number 8 are the names of the three astronauts.The initial design of the insignia was developed by Jim Lovell. Lovell reportedly sketched the initial design while riding in the backseat of a T-38 flight from California to Houston, shortly after learning of the re-designation of the flight to become a lunar-orbital mission. The graphic design of the insignia was done by Houston artist and animator William Bradley. == Planning == Apollo 4 and Apollo 6 had been "A" missions, unmanned tests of the Saturn V launch vehicle using an unmanned Block I production model of the Apollo Command and Service Module in Earth orbit. Apollo 7, scheduled for October 1968, would be a manned Earth-orbit flight of the CSM, completing the objectives for Mission "C". Further missions depended on the readiness of the Lunar Module. Apollo 8 was planned as the "D" mission, to test the LM in a low Earth orbit in December 1968 by James McDivitt, David Scott and Russell Schweickart, while Borman's crew would fly the "E" mission, a more rigorous LM test in an elliptical medium Earth orbit as Apollo 9, in early 1969. But production of the LM fell behind schedule, and when Apollo 8's LM arrived at the Kennedy Space Center in June 1968, significant defects were discovered, leading Grumman, the lead contractor for the LM, to predict that the first mission-ready LM would not be ready until at least February 1969. This would mean delaying the "D" and subsequent missions, endangering the program's goal of a lunar landing before the end of 1969.George Low, the Manager of the Apollo Spacecraft Program Office, proposed a solution in August to keep the program on track despite the LM delay. Since the Command/Service Module (CSM) would be ready three months before the Lunar Module, a CSM-only mission could be flown in December 1968. Instead of just repeating the "C" mission flight of Apollo 7, this CSM could be sent all the way to the Moon, with the possibility of entering a lunar orbit. The new mission would also allow NASA to test lunar landing procedures that would otherwise have to wait until Apollo 10, the scheduled "F" mission. This also meant that the medium Earth orbit "E" mission could be dispensed with. The net result was that only the "D" mission had to be delayed. Almost every senior manager at NASA agreed with this new mission, citing both confidence in the hardware and personnel, and the potential for a significant morale boost provided by a circumlunar flight. The only person who needed some convincing was James E. Webb, the NASA administrator. With the rest of his agency in support of the new mission, Webb eventually approved the mission change. The mission was officially changed from a "D" mission to a "C-Prime" lunar-orbit mission, but was still referred to in press releases as an Earth-orbit mission at Webb's direction. No public announcement was made about the change in mission until November 12, three weeks after Apollo 7's successful Earth-orbit mission and less than 40 days before launch.With the change in mission for Apollo 8, Director of Flight Crew Operations Deke Slayton decided to swap the crews of the D and E missions. This swap also meant a swap of spacecraft, requiring Borman's crew to use CSM-103, while McDivitt's crew would use CSM-104.On September 9, the crew entered the simulators to begin their preparation for the flight. By the time the mission flew, the crew had spent seven hours training for every actual hour of flight. Although all crew members were trained in all aspects of the mission, it was necessary to specialize. Borman, as commander, was given training on controlling the spacecraft during the re-entry. Lovell was trained on navigating the spacecraft in case communication was lost with the Earth. Anders was placed in charge of checking that the spacecraft was in working order.Added pressure on the Apollo program to make its 1969 landing goal was provided by the Soviet Union's flight of some living creatures, including Russian tortoises, in a cislunar loop around the Moon on Zond 5 and return to Earth on September 21. There was speculation within NASA and the press that they might be preparing to launch cosmonauts on a similar circumlunar mission before the end of 1968.The Apollo 8 crew, now living in the crew quarters at Kennedy Space Center, received a visit from Charles Lindbergh and his wife, Anne Morrow Lindbergh, the night before the launch. They talked about how, before his 1927 flight, Lindbergh had used a piece of string to measure the distance from New York City to Paris on a globe and from that calculated the fuel needed for the flight. The total was a tenth of the amount that the Saturn V would burn every second. The next day, the Lindberghs watched the launch of Apollo 8 from a nearby dune. == Saturn V == The Saturn V rocket used by Apollo 8 was designated SA-503, or the "03rd" model of the Saturn V ("5") Rocket to be used in the Saturn-Apollo ("SA") program. When it was erected in the Vertical Assembly Building on December 20, 1967, it was thought that the rocket would be used for an unmanned Earth-orbit test flight carrying a boilerplate Command/Service Module. Apollo 6 had suffered several major problems during its April 1968 flight, including severe pogo oscillation during its first stage, two second stage engine failures, and a third stage that failed to reignite in orbit. Without assurances that these problems had been rectified, NASA administrators could not justify risking a manned mission until additional unmanned test flights proved that the Saturn V was ready.Teams from the Marshall Space Flight Center (MSFC) went to work on the problems. Of primary concern was the pogo oscillation, which would not only hamper engine performance, but could exert significant g-forces on a crew. A task force of contractors, NASA agency representatives, and MSFC researchers concluded that the engines vibrated at a frequency similar to the frequency at which the spacecraft itself vibrated, causing a resonance effect that induced oscillations in the rocket. A system using helium gas to absorb some of these vibrations was installed.Of equal importance was the failure of three engines during flight. Researchers quickly determined that a leaking hydrogen fuel line ruptured when exposed to vacuum, causing a loss of fuel pressure in engine two. When an automatic shutoff attempted to close the liquid hydrogen valve and shut down engine two, it accidentally shut down engine three's liquid oxygen due to a miswired connection. As a result, engine three failed within one second of engine two's shutdown. Further investigation revealed the same problem for the third-stage engine—a faulty igniter line. The team modified the igniter lines and fuel conduits, hoping to avoid similar problems on future launches.The teams tested their solutions in August 1968 at the Marshall Space Flight Center. A Saturn stage IC was equipped with shock absorbing devices to demonstrate the team's solution to the problem of pogo oscillation, while a Saturn Stage II was retrofitted with modified fuel lines to demonstrate their resistance to leaks and ruptures in vacuum conditions. Once NASA administrators were convinced that the problems were solved, they gave their approval for a manned mission using SA-503.The Apollo 8 spacecraft was placed on top of the rocket on September 21 and the rocket made the slow 3-mile (5 km) journey to the launch pad on October 9. Testing continued all through December until the day before launch, including various levels of readiness testing from December 5 through 11. Final testing of modifications to address the problems of pogo oscillation, ruptured fuel lines, and bad igniter lines took place on December 18, a mere three days before the scheduled launch. == Mission == === Parameter summary === As the first manned spacecraft to orbit more than one celestial body, Apollo 8's profile had two different sets of orbital parameters, separated by a translunar injection maneuver. Apollo lunar missions would begin with a nominal 100-nautical-mile (185.2 km) circular Earth parking orbit. Apollo 8 was launched into an initial orbit with an apogee of 99.99 nautical miles (185.18 km) and a perigee of 99.57 nautical miles (184.40 km), with an inclination of 32.51° to the Equator, and an orbital period of 88.19 minutes. Propellant venting increased the apogee by 6.4 nautical miles (11.9 km) over the 2 hours, 44 minutes and 30 seconds spent in the parking orbit.This was followed by a Trans-Lunar Injection (TLI) burn of the S-IVB third stage for 318 seconds, accelerating the 63,650 lb (28,870 kg) Command/Service Module and 19,900 lb (9,000 kg) LM test article from an orbital velocity of 25,567 feet per second (7,793 m/s) to the injection velocity of 35,505 ft/s (10,822 m/s), which set a record for the highest speed, relative to Earth, that humans had ever traveled. This speed was slightly less than the Earth's escape velocity of 36,747 feet per second (11,200 m/s), but put Apollo 8 into an elongated elliptical Earth orbit, to a point where the Moon's gravity would capture it.The standard lunar orbit for Apollo missions was planned as a nominal 60-nautical-mile (110 km) circular orbit above the Moon's surface. Initial lunar orbit insertion was an ellipse with a perilune of 60.0 nautical miles (111.1 km) and an apolune of 168.5 nautical miles (312.1 km), at an inclination of 12° from the lunar equator. This was then circularized at 60.7 nautical miles (112.4 km) by 59.7 nautical miles (110.6 km), with an orbital period of 128.7 minutes. The effect of lunar mass concentrations ("masscons") on the orbit was found to be greater than initially predicted; over the course of the ten lunar orbits lasting twenty hours, the orbital distance was perturbated to 63.6 nautical miles (117.8 km) by 58.6 nautical miles (108.5 km).Apollo 8 achieved a maximum distance from Earth of 203,752 nautical miles (234,474 statute miles; 377,349 kilometers). === Launch and trans-lunar injection === Apollo 8 launched at 7:51:00 a.m. Eastern Standard Time on December 21, 1968, using the Saturn V's three stages to achieve Earth orbit. The S-IC first stage impacted the Atlantic Ocean at 30°12′N 74°7′W and the S-II second stage at 31°50′N 37°17′W. The S-IVB third stage injected the craft into Earth orbit, but remained attached to later perform the trans-lunar injection (TLI) burn that put the spacecraft on a trajectory to the Moon. Once the vehicle reached Earth orbit, both the crew and Houston flight controllers spent the next 2 hours and 38 minutes checking that the spacecraft was in proper working order and ready for TLI. The proper operation of the S-IVB third stage of the rocket was crucial: in the last unmanned test, it had failed to re-ignite for TLI.During the flight, three fellow astronauts served on the ground as Capsule Communicators (usually referred to as "CAPCOMs") on a rotating schedule. The CAPCOMs were the only people who regularly communicated with the crew. Michael Collins was the first CAPCOM on duty and at 2 hours, 27 minutes and 22 seconds after launch radioed, "Apollo 8. You are Go for TLI." This communication signified that Mission Control had given official permission for Apollo 8 to go to the Moon. Over the next 12 minutes before the TLI burn, the Apollo 8 crew continued to monitor the spacecraft and the S-IVB. The engine ignited on time and performed the TLI burn perfectly. After the S-IVB had performed its required tasks, it was jettisoned. The crew then rotated the spacecraft to take some photographs of the spent stage and then practiced flying in formation with it. As the crew rotated the spacecraft, they had their first views of the Earth as they moved away from it. This marked the first time humans could view the whole Earth at once. Borman became worried that the S-IVB was staying too close to the Command/Service Module and suggested to Mission Control that the crew perform a separation maneuver. Mission Control first suggested pointing the spacecraft towards Earth and using the Reaction Control System (RCS) thrusters on the Service Module (SM) to add 3 ft/s (0.91 m/s) away from the Earth, but Borman did not want to lose sight of the S-IVB. After discussion, the crew and Mission Control decided to burn in this direction, but at 9 ft/s (2.7 m/s) instead. These discussions put the crew an hour behind their flight plan. Five hours after launch, Mission Control sent a command to the S-IVB booster to vent its remaining fuel through its engine bell to change the booster's trajectory. This S-IVB would then pass the Moon and enter into a solar orbit, posing no further hazard to Apollo 8. The S-IVB subsequently went into a 0.99-by-0.92-astronomical-unit (148 by 138 Gm) solar orbit with an inclination of 23.47° from the plane of the ecliptic, and an orbital period of 340.80 days. After the insertion into trans-Lunar orbit, the Saturn IVB third stage became a derelict object. It will continue to orbit the Sun for many years.The Apollo 8 crew were the first humans to pass through the Van Allen radiation belts, which extend up to 15,000 miles (24,000 km) from Earth. Scientists predicted that passing through the belts quickly at the spacecraft's high speed would cause a radiation dosage of no more than a chest X-ray, or 1 milligray (during a year, the average human receives a dose of 2 to 3 mGy). To record the actual radiation dosages, each crew member wore a Personal Radiation Dosimeter that transmitted data to Earth as well as three passive film dosimeters that showed the cumulative radiation experienced by the crew. By the end of the mission, the crew experienced an average radiation dose of 1.6 mGy. === Lunar trajectory === Jim Lovell's main job as Command Module Pilot was as navigator. Although Mission Control performed all the actual navigation calculations, it was necessary to have a crew member serving as navigator so that the crew could return to Earth in case of loss of communication with Mission Control. Lovell navigated by star sightings using a sextant built into the spacecraft, measuring the angle between a star and the Earth's (or the Moon's) horizon. This task was difficult, because a large cloud of debris around the spacecraft, formed by the venting S-IVB, made it hard to distinguish the stars. By seven hours into the mission, the crew was about one hour and 40 minutes behind flight plan, because of the problems in moving away from the S-IVB and Lovell's obscured star sightings. The crew now placed the spacecraft into Passive Thermal Control (PTC), also called "barbecue roll", in which the spacecraft rotated about once per hour around its long axis to ensure even heat distribution across the surface of the spacecraft. In direct sunlight, the spacecraft could be heated to over 200 °C (392 °F) while the parts in shadow would be −100 °C (−148 °F). These temperatures could cause the heat shield to crack and propellant lines to burst. Because it was impossible to get a perfect roll, the spacecraft swept out a cone as it rotated. The crew had to make minor adjustments every half hour as the cone pattern got larger and larger.The first mid-course correction came 11 hours into the flight. Testing on the ground had shown that the Service Propulsion System (SPS) engine had a small chance of exploding when burned for long periods unless its combustion chamber was "coated" first. Burning the engine for a short period would accomplish coating. This first correction burn was only 2.4 seconds and added about 20.4 ft/s (6.2 m/s) velocity prograde (in the direction of travel). This change was less than the planned 24.8 ft/s (7.6 m/s), because of a bubble of helium in the oxidizer lines, which caused unexpectedly low propellant pressure. The crew had to use the small RCS thrusters to make up the shortfall. Two later planned mid-course corrections were canceled because the Apollo 8 trajectory was found to be perfect.Eleven hours into the flight, the crew had been awake for more than 16 hours. Before launch, NASA had decided that at least one crew member should be awake at all times to deal with problems that might arise. Borman started the first sleep shift, but found sleeping difficult because of the constant radio chatter and mechanical noises.About an hour after starting his sleep shift, Borman obtained permission from ground control to take a Seconal sleeping pill. The pill had little effect. Borman eventually fell asleep, and then awoke feeling ill. He vomited twice and had a bout of diarrhea; this left the spacecraft full of small globules of vomit and feces, which the crew cleaned up as well as they could. Borman initially did not want everyone to know about his medical problems, but Lovell and Anders wanted to inform Mission Control. The crew decided to use the Data Storage Equipment (DSE), which could tape voice recordings and telemetry and dump them to Mission Control at high speed. After recording a description of Borman's illness they asked Mission Control to check the recording, stating that they "would like an evaluation of the voice comments".The Apollo 8 crew and Mission Control medical personnel held a conference using an unoccupied second-floor control room (there were two identical control rooms in Houston, on the second and third floors, only one of which was used during a mission). The conference participants concluded that there was little to worry about and that Borman's illness was either a 24-hour flu, as Borman thought, or a reaction to the sleeping pill. Researchers now believe that he was suffering from space-adaptation syndrome, which affects about a third of astronauts during their first day in space as their vestibular system adapts to weightlessness. Space-adaptation syndrome had not occurred on previous spacecraft (Mercury and Gemini), because those astronauts couldn't move freely in the small cabins of those spacecraft. The increased cabin space in the Apollo Command Module afforded astronauts greater freedom of movement, contributing to symptoms of space sickness for Borman and, later, astronaut Russell Schweickart during Apollo 9. The cruise phase was a relatively uneventful part of the flight, except for the crew checking that the spacecraft was in working order and that they were on course. During this time, NASA scheduled a television broadcast at 31 hours after launch. The Apollo 8 crew used a 2 kg camera that broadcast in black-and-white only, using a Vidicon tube. The camera had two lenses, a very wide-angle (160°) lens, and a telephoto (9°) lens.During this first broadcast, the crew gave a tour of the spacecraft and attempted to show how the Earth appeared from space. However, difficulties aiming the narrow-angle lens without the aid of a monitor to show what it was looking at made showing the Earth impossible. Additionally, the Earth image became saturated by any bright source without proper filters. In the end, all the crew could show the people watching back on Earth was a bright blob. After broadcasting for 17 minutes, the rotation of the spacecraft took the high-gain antenna out of view of the receiving stations on Earth and they ended the transmission with Lovell wishing his mother a happy birthday.By this time, the crew had completely abandoned the planned sleep shifts. Lovell went to sleep 32½ hours into the flight—3½ hours before he had planned to. A short while later, Anders also went to sleep after taking a sleeping pill.The crew was unable to see the Moon for much of the outward cruise. Two factors made the Moon almost impossible to see from inside the spacecraft: three of the five windows fogging up due to out-gassed oils from the silicone sealant, and the attitude required for the PTC. It was not until the crew had gone behind the Moon that they would be able to see it for the first time.Apollo 8 made a second television broadcast at 55 hours into the flight. This time, the crew rigged up filters meant for the still cameras so they could acquire images of the Earth through the telephoto lens. Although difficult to aim, as they had to maneuver the entire spacecraft, the crew was able to broadcast back to Earth the first television pictures of the Earth. The crew spent the transmission describing the Earth and what was visible and the colors they could see. The transmission lasted 23 minutes. === Lunar sphere of influence === At about 55 hours and 40 minutes into the flight, the crew of Apollo 8 became the first humans to enter the gravitational sphere of influence of another celestial body. In other words, the effect of the Moon's gravitational force on Apollo 8 became stronger than that of the Earth. At the time it happened, Apollo 8 was 38,759 miles (62,377 km) from the Moon and had a speed of 3,990 ft/s (1,220 m/s) relative to the Moon. This historic moment was of little interest to the crew since they were still calculating their trajectory with respect to the launch pad at Kennedy Space Center. They would continue to do so until they performed their last mid-course correction, switching to a reference frame based on ideal orientation for the second engine burn they would make in lunar orbit. It was only 13 hours until they would be in lunar orbit.The last major event before Lunar Orbit Insertion (LOI) was a second mid-course correction. It was in retrograde (against direction of travel) and slowed the spacecraft down by 2.0 ft/s (0.61 m/s), effectively lowering the closest distance that the spacecraft would pass the moon. At exactly 61 hours after launch, about 24,200 miles (38,900 km) from the Moon, the crew burned the RCS for 11 seconds. They would now pass 71.7 miles (115.4 km) from the lunar surface.At 64 hours into the flight, the crew began to prepare for Lunar Orbit Insertion-1 (LOI-1). This maneuver had to be performed perfectly, and due to orbital mechanics had to be on the far side of the Moon, out of contact with the Earth. After Mission Control was polled for a "go/no go" decision, the crew was told at 68 hours, they were Go and "riding the best bird we can find". Lovell replied, "We'll see you on the other side", and for the first time in history, humans travelled behind the Moon and out of radio contact with the Earth.With 10 minutes before the LOI-1, the crew began one last check of the spacecraft systems and made sure that every switch was in the correct place. At that time, they finally got their first glimpses of the Moon. They had been flying over the unlit side, and it was Lovell who saw the first shafts of sunlight obliquely illuminating the lunar surface. The LOI burn was only two minutes away, so the crew had little time to appreciate the view. === Lunar orbit === The SPS ignited at 69 hours, 8 minutes, and 16 seconds after launch and burned for 4 minutes and 7 seconds, placing the Apollo 8 spacecraft in orbit around the Moon. The crew described the burn as being the longest four minutes of their lives. If the burn had not lasted exactly the correct amount of time, the spacecraft could have ended up in a highly elliptical lunar orbit or even flung off into space. If it lasted too long they could have struck the Moon. After making sure the spacecraft was working, they finally had a chance to look at the Moon, which they would orbit for the next 20 hours.On Earth, Mission Control continued to wait. If the crew had not burned the engine or the burn had not lasted the planned length of time, the crew would appear early from behind the Moon. However, this time came and went without Apollo 8 reappearing. Exactly at the calculated moment, the signal was received from the spacecraft, indicating it was in a 193.3-by-69.5-mile (311.1 by 111.8 km) orbit about the Moon.After reporting on the status of the spacecraft, Lovell gave the first description of what the lunar surface looked like: The Moon is essentially grey, no color; looks like plaster of Paris or sort of a grayish beach sand. We can see quite a bit of detail. The Sea of Fertility doesn't stand out as well here as it does back on Earth. There's not as much contrast between that and the surrounding craters. The craters are all rounded off. There's quite a few of them, some of them are newer. Many of them look like—especially the round ones—look like hit by meteorites or projectiles of some sort. Langrenus is quite a huge crater; it's got a central cone to it. The walls of the crater are terraced, about six or seven different terraces on the way down. Lovell continued to describe the terrain they were passing over. One of the crew's major tasks was reconnaissance of planned future landing sites on the Moon, especially one in Mare Tranquillitatis that would be the Apollo 11 landing site. The launch time of Apollo 8 had been chosen to give the best lighting conditions for examining the site. A film camera had been set up in one of the spacecraft windows to record a frame every second of the Moon below. Bill Anders spent much of the next 20 hours taking as many photographs as possible of targets of interest. By the end of the mission the crew had taken 700 photographs of the Moon and 150 of the Earth.Throughout the hour that the spacecraft was in contact with Earth, Borman kept asking how the data for the SPS looked. He wanted to make sure that the engine was working and could be used to return early to the Earth if necessary. He also asked that they receive a "go/no go" decision before they passed behind the Moon on each orbit.As they reappeared for their second pass in front of the Moon, the crew set up the equipment to broadcast a view of the lunar surface. Anders described the craters that they were passing over. At the end of this second orbit they performed the 11-second LOI-2 burn of the SPS to circularize the orbit to 70.0 by 71.3 miles (112.7 by 114.7 km).Through the next two orbits, the crew continued to keep check of the spacecraft and to observe and photograph the Moon. During the third pass, Borman read a small prayer for his church. He had been scheduled to participate in a service at St. Christopher's Episcopal Church near Seabrook, Texas, but due to the Apollo 8 flight he was unable to. A fellow parishioner and engineer at Mission Control, Rod Rose, suggested that Borman read the prayer which could be recorded and then replayed during the service. ==== Earthrise ==== When the spacecraft came out from behind the Moon for its fourth pass across the front, the crew witnessed "Earthrise" for the first time in human history (NASA's Lunar Orbiter 1 took the very first picture of an Earthrise from the vicinity of the Moon, on August 23, 1966). Anders saw the Earth emerging from behind the lunar horizon, and then called in excitement to the others, taking a black-and-white photograph as he did so. Anders asked Lovell for a color film and then took Earthrise, a more famous color photo, later picked by Life magazine as one of its hundred photos of the century.Due to the synchronous rotation of the Moon about the Earth, Earthrise is not generally visible from the lunar surface. Earthrise is generally only visible when orbiting the Moon, other than at selected places near the Moon's limb, where libration carries the Earth slightly above and below the lunar horizon. Anders continued to take photographs while Lovell assumed control of the spacecraft so Borman could rest. Despite the difficulty resting in the cramped and noisy spacecraft, Borman was able to sleep for two orbits, awakening periodically to ask questions about their status. Borman awoke fully, however, when he started to hear his fellow crew members make mistakes. They were beginning to not understand questions and would have to ask for the answers to be repeated. Borman realized that everyone was extremely tired from not having a good night's sleep in over three days. He ordered Anders and Lovell to get some sleep and that the rest of the flight plan regarding observing the Moon be scrubbed. At first Anders protested saying that he was fine, but Borman would not be swayed. At last Anders agreed as long as Borman would set up the camera to continue to take automatic shots of the Moon. Borman also remembered that there was a second television broadcast planned, and with so many people expected to be watching he wanted the crew to be alert. For the next two orbits Anders and Lovell slept while Borman sat at the helm. On subsequent Apollo missions, crews would avoid this situation by sleeping on the same schedule. As they rounded the Moon for the ninth time, the second television transmission began. Borman introduced the crew, followed by each man giving his impression of the lunar surface and what it was like to be orbiting the Moon. Borman described it as being "a vast, lonely, forbidding expanse of nothing". Then, after talking about what they were flying over, Anders said that the crew had a message for all those on Earth. Each man on board read a section from the Biblical creation story from the Book of Genesis. Borman finished the broadcast by wishing a Merry Christmas to everyone on Earth. His message appeared to sum up the feelings that all three crewmen had from their vantage point in lunar orbit. Borman said, "And from the crew of Apollo 8, we close with good night, good luck, a Merry Christmas and God bless all of you—all of you on the good Earth."The only task left for the crew at this point was to perform the Trans-Earth Injection (TEI), which was scheduled for 2½ hours after the end of the television transmission. The TEI was the most critical burn of the flight, as any failure of the SPS to ignite would strand the crew in lunar orbit, with little hope of escape. As with the previous burn, the crew had to perform the maneuver above the far side of the Moon, out of contact with Earth. The burn occurred exactly on time. The spacecraft telemetry was reacquired as it re-emerged from behind the Moon at 89 hours, 28 minutes, and 39 seconds, the exact time calculated. When voice contact was regained, Lovell announced, "Please be informed, there is a Santa Claus", to which Ken Mattingly, the current CAPCOM, replied, "That's affirmative, you are the best ones to know." The spacecraft began its journey back to Earth on December 25, Christmas Day. === Unplanned manual re-alignment === Later, Lovell used some otherwise idle time to do some navigational sightings, maneuvering the module to view various stars by using the computer keyboard. However, he accidentally erased some of the computer's memory, which caused the Inertial Measurement Unit (IMU) to think the module was in the same relative position it had been in before lift-off and fire the thrusters to "correct" the module's attitude.Once the crew realized why the computer had changed the module's attitude, they realized they would have to re-enter data that would tell the computer its real position. It took Lovell ten minutes to figure out the right numbers, using the thrusters to get the stars Rigel and Sirius aligned, and another 15 minutes to enter the corrected data into the computer.Sixteen months later, Lovell would once again have to perform a similar manual re-alignment, under more critical conditions, during the Apollo 13 mission, after that module's IMU had to be turned off to conserve energy. In his 1994 book, Lost Moon: The Perilous Voyage of Apollo 13, Lovell wrote, "My training [on Apollo 8] came in handy!" In that book he dismissed the incident as a "planned experiment", requested by the ground crew. In subsequent interviews Lovell has acknowledged that the incident was an accident, caused by his mistake. === Cruise back to Earth and re-entry === The cruise back to Earth was mostly a time for the crew to relax and monitor the spacecraft. As long as the trajectory specialists had calculated everything correctly, the spacecraft would re-enter two-and-half days after TEI and splashdown in the Pacific. On Christmas afternoon, the crew made their fifth television broadcast. This time they gave a tour of the spacecraft, showing how an astronaut lived in space. When they finished broadcasting they found a small present from Deke Slayton in the food locker: a real turkey dinner with stuffing, in the same kind of pack that the troops in Vietnam received. Another Slayton surprise was a gift of three miniature bottles of brandy, that Borman ordered the crew to leave alone until after they landed. They remained unopened, even years after the flight. There were also small presents to the crew from their wives. The next day, at about 124 hours into the mission, the sixth and final TV transmission showed the mission's best video images of the earth, in a four-minute broadcast. After two uneventful days the crew prepared for re-entry. The computer would control the re-entry and all the crew had to do was put the spacecraft in the correct attitude, blunt end forward. If the computer broke down, Borman would take over.Once the Command Module was separated from the Service Module, the astronauts were committed to re-entry. Six minutes before they hit the top of the atmosphere, the crew saw the Moon rising above the Earth's horizon, just as had been predicted by the trajectory specialists. As they hit the thin outer atmosphere they noticed it was becoming hazy outside as glowing plasma formed around the spacecraft. The spacecraft started slowing down and the deceleration peaked at 6 g (59 m/s2). With the computer controlling the descent by changing the attitude of the spacecraft, Apollo 8 rose briefly like a skipping stone before descending to the ocean. At 30,000 feet (9.1 km) the drogue parachute stabilized the spacecraft and was followed at 10,000 feet (3.0 km) by the three main parachutes. The spacecraft splashdown position was officially reported as 8°8′N 165°1′W in the North Pacific Ocean south of Hawaii.When it hit the water, the parachutes dragged the spacecraft over and left it upside down, in what was termed Stable 2 position. About six minutes later the Command Module was righted into its normal apex-up splashdown orientation by the inflatable bag uprighting system. As they were buffeted by a 10-foot (3.0 m) swell, Borman was sick, waiting for the three flotation balloons to right the spacecraft. It was 43 minutes after splashdown before the first frogman from USS Yorktown arrived, as the spacecraft had landed before sunrise. Forty-five minutes later, the crew was safe on the deck of the aircraft carrier. == Historical importance == Apollo 8 came at the end of 1968, a year that had seen much upheaval in the United States and most of the world. Even though the year saw political assassinations, political unrest in the streets of Europe and America, and the Prague Spring, Time magazine chose the crew of Apollo 8 as its Men of the Year for 1968, recognizing them as the people who most influenced events in the preceding year. They had been the first people ever to leave the gravitational influence of the Earth and orbit another celestial body. They had survived a mission that even the crew themselves had rated as only having a fifty-fifty chance of fully succeeding. The effect of Apollo 8 can be summed up by a telegram from a stranger, received by Borman after the mission, that simply stated, "Thank you Apollo 8. You saved 1968." One of the most famous aspects of the flight was the Earthrise picture that was taken as they came around for their fourth orbit of the Moon. This was the first time that humans had taken such a picture while actually behind the camera, and it has been credited with a role in inspiring the first Earth Day in 1970. It was selected as the first of Life magazine's 100 Photographs That Changed the World. Apollo 11 astronaut Michael Collins said, "Eight's momentous historic significance was foremost"; while space historian Robert K. Poole saw Apollo 8 as the most historically significant of all the Apollo missions.The mission was the most widely covered by the media since the first American orbital flight, Mercury-Atlas 6 by John Glenn in 1962. There were 1200 journalists covering the mission, with the BBC coverage being broadcast in 54 countries in 15 different languages. The Soviet newspaper Pravda featured a quote from Boris Nikolaevich Petrov, Chairman of the Soviet Interkosmos program, who described the flight as an "outstanding achievement of American space sciences and technology". It is estimated that a quarter of the people alive at the time saw—either live or delayed—the Christmas Eve transmission during the ninth orbit of the Moon. The Apollo 8 broadcasts won an Emmy Award, the highest honor given by the Academy of Television Arts & Sciences. Madalyn Murray O'Hair, an atheist, later caused controversy by bringing a lawsuit against NASA over the reading from Genesis. O'Hair wished the courts to ban American astronauts—who were all government employees—from public prayer in space. Though the case was rejected by the Supreme Court of the United States for lack of jurisdiction, it caused NASA to be skittish about the issue of religion throughout the rest of the Apollo program. Buzz Aldrin, on Apollo 11, self-communicated Presbyterian Communion on the surface of the Moon after landing; he refrained from mentioning this publicly for several years, and only obliquely referred to it at the time.In 1969, the United States Postal Service issued a postage stamp (Scott catalogue #1371) commemorating the Apollo 8 flight around the Moon. The stamp featured a detail of the famous photograph of the Earthrise over the Moon taken by Anders on Christmas Eve, and the words, "In the beginning God ..." Just 18 days after the crew's return to Earth, they were featured during the 1969 Super Bowl pre-game show reciting the Pledge of Allegiance prior to the national anthem being performed by Anita Bryant. == Spacecraft location == In January 1970, the spacecraft was delivered to Osaka, Japan, for display in the U.S. pavilion at Expo '70. It is now displayed at the Chicago Museum of Science and Industry, along with a collection of personal items from the flight donated by Lovell and the space suit worn by Frank Borman. Jim Lovell's Apollo 8 space suit is on public display in the Visitor Center at NASA's Glenn Research Center. Bill Anders's space suit is on display at the Science Museum in London, United Kingdom. == In popular culture == Apollo 8's historic mission has been shown and referred to in several forms, both documentary and fiction. The various television transmissions and 16 mm footage shot by the crew of Apollo 8 was compiled and released by NASA in the 1969 documentary, Debrief: Apollo 8, which was hosted by Burgess Meredith. In addition, Spacecraft Films released, in 2003, a three-disc DVD set containing all of NASA's TV and 16 mm film footage related to the mission including all TV transmissions from space, training and launch footage, and motion pictures taken in flight. Portions of the Apollo 8 mission can be seen in the 1989 documentary For All Mankind, which won the Grand Jury Prize Documentary at the Sundance Film Festival. The television series American Experience aired a documentary, "Race to the Moon", in 2005 during season 18. The Apollo 8 mission was well covered in the 2007 British documentary In the Shadow of the Moon.Portions of the mission are dramatized in the 1998 miniseries From the Earth to the Moon episode "1968". The S-IVB stage of Apollo 8 was also portrayed as the location of an alien device in the 1970 UFO episode "Conflict".The mission was also featured in the Discovery Channel's 6-part documentary series When We Left Earth: The NASA Missions (Part 3, "Landing the Eagle"). All three astronauts were featured in this documentary, telling the story of their historic mission to the Moon in their own words.Footage of Apollo 8 appears in the Dawn of the Planet of the Apes movie. A clip of Frank Borman is shown on the news on TV in the background while the news covered the first manned mission to Mars.Apollo 8's Lunar Orbit Insertion One was chronicled with actual recordings in the song "The Other Side" on the album The Race for Space by the band Public Service Broadcasting. == See also == == Notes == == References == This article incorporates public domain material from websites or documents of the National Aeronautics and Space Administration. == Bibliography == == External links == "Apollo 8" at Encyclopedia Astronautica Jackson, Albert A.

### Instruction: retrieve labels for this: An astronaut or cosmonaut is a person trained by a human spaceflight program to command, pilot, or serve as a crew member of a spacecraft. Although generally reserved for professional space travelers, the terms are sometimes applied to anyone who travels into space, including scientists, politicians, journalists, and tourists.Until 2002, astronauts were sponsored and trained exclusively by governments, either by the military or by civilian space agencies. With the suborbital flight of the privately funded SpaceShipOne in 2004, a new category of astronaut was created: the commercial astronaut. == Definition == The criteria for what constitutes human spaceflight vary. The Fédération Aéronautique Internationale (FAI) Sporting Code for astronautics recognizes only flights that exceed an altitude of 100 kilometers (62 mi). In the United States, professional, military, and commercial astronauts who travel above an altitude of 50 miles (80 km) are awarded astronaut wings. As of 17 November 2016, a total of 552 people from 36 countries have reached 100 km (62 mi) or more in altitude, of which 549 reached low Earth orbit or beyond. Of these, 24 people have traveled beyond low Earth orbit, either to lunar orbit, the lunar surface, or, in one case, a loop around the Moon. Three of the 24–Jim Lovell, John Young and Eugene Cernan–did so twice. The three current astronauts who have flown without reaching low Earth orbit are spaceplane pilots Joe Walker, Mike Melvill, and Brian Binnie, who participated in suborbital missions. As of 17 November 2016, under the U.S. definition, 558 people qualify as having reached space, above 50 miles (80 km) altitude. Of eight X-15 pilots who exceeded 50 miles (80 km) in altitude, only one exceeded 100 kilometers (about 62 miles). Space travelers have spent over 41,790 man-days (114.5 man-years) in space, including over 100 astronaut-days of spacewalks. As of 2016, the man with the longest cumulative time in space is Gennady Padalka, who has spent 879 days in space. Peggy A. Whitson holds the record for the most time in space by a woman, 377 days. == Terminology == In 1959, when both the United States and Soviet Union were planning, but had yet to launch humans into space, NASA Administrator T. Keith Glennan and his Deputy Administrator, Dr. Hugh Dryden, discussed whether spacecraft crew members should be called astronauts or cosmonauts. Dryden preferred "cosmonaut", on the grounds that flights would occur in the cosmos (near space), while the "astro" prefix suggested flight to the stars. Most NASA Space Task Group members preferred "astronaut", which survived by common usage as the preferred American term. When the Soviet Union launched the first man into space, Yuri Gagarin in 1961, they chose a term which anglicizes to "cosmonaut". === English === In English-speaking nations, a professional space traveler is called an astronaut. The term derives from the Greek words ástron (ἄστρον), meaning "star", and nautes (ναύτης), meaning "sailor". The first known use of the term "astronaut" in the modern sense was by Neil R. Jones in his 1930 short story "The Death's Head Meteor". The word itself had been known earlier; for example, in Percy Greg's 1880 book Across the Zodiac, "astronaut" referred to a spacecraft. In Les Navigateurs de l'Infini (1925) by J.-H. Rosny aîné, the word astronautique (astronautic) was used. The word may have been inspired by "aeronaut", an older term for an air traveler first applied in 1784 to balloonists. An early use of "astronaut" in a non-fiction publication is Eric Frank Russell's poem "The Astronaut", appearing in the November 1934 Bulletin of the British Interplanetary Society.The first known formal use of the term astronautics in the scientific community was the establishment of the annual International Astronautical Congress in 1950, and the subsequent founding of the International Astronautical Federation the following year.NASA applies the term astronaut to any crew member aboard NASA spacecraft bound for Earth orbit or beyond. NASA also uses the term as a title for those selected to join its Astronaut Corps. The European Space Agency similarly uses the term astronaut for members of its Astronaut Corps. === Russian === By convention, an astronaut employed by the Russian Federal Space Agency (or its Soviet predecessor) is called a cosmonaut in English texts. The word is an anglicisation of the Russian word kosmonavt (Russian: космонавт Russian pronunciation: [kəsmɐˈnaft]), one who works in space outside the Earth's atmosphere, a space traveler, which derives from the Greek words kosmos (κόσμος), meaning "universe", and nautes (ναύτης), meaning "sailor". Other countries of the former Eastern Bloc use variations of the Russian word kosmonavt, such as the Polish kosmonauta. Coinage of the term kosmonavt has been credited to Soviet aeronautics pioneer Mikhail Tikhonravov (1900–1974). The first cosmonaut was Soviet Air Force pilot Yuri Gagarin, also the first person in space. Valentina Tereshkova, a Russian factory worker, was the first woman in space, as well as the first civilian among the Soviet cosmonaut or NASA astronaut corps to make a spaceflight. On March 14, 1995, Norman Thagard became the first American to ride to space on board a Russian launch vehicle, and thus became the first "American cosmonaut". === Chinese === "Yǔ háng yuán" (宇航员, "Space-universe navigating personnel") is used for astronauts and cosmonauts in general, while "Hángtiān yuán" (航天员, "navigating outer space personnel") is used for Chinese astronauts. Here, "Hángtiān" (航天) is strictly defined as the navigation of outer space within the local star system, i.e. Solar system. The phrase "tài kōng rén" (太空人, "spaceman") is often used in Hong Kong and Taiwan.The term taikonaut is used by some English-language news media organizations for professional space travelers from China. The word has featured in the Longman and Oxford English dictionaries, the latter of which describes it as "a hybrid of the Chinese term taikong (space) and the Greek naut (sailor)"; the term became more common in 2003 when China sent its first astronaut Yang Liwei into space aboard the Shenzhou 5 spacecraft. This is the term used by Xinhua News Agency in the English version of the Chinese People's Daily since the advent of the Chinese space program. The origin of the term is unclear; as early as May 1998, Chiew Lee Yih (趙裡昱) from Malaysia, used it in newsgroups. === Other terms === With the rise of space tourism, NASA and the Russian Federal Space Agency agreed to use the term "spaceflight participant" to distinguish those space travelers from professional astronauts on missions coordinated by those two agencies. While no nation other than the Russian Federation (and previously the former Soviet Union), the United States, and China have launched a manned spacecraft, several other nations have sent people into space in cooperation with one of these countries. Inspired partly by these missions, other synonyms for astronaut have entered occasional English usage. For example, the term spationaut (French spelling: spationaute) is sometimes used to describe French space travelers, from the Latin word spatium for "space", the Malay term angkasawan was used to describe participants in the Angkasawan program, and the Indian Space Research Organisation hope to launch a spacecraft in 2018 that would carry vyomanauts, coined from the Sanskrit word for space. In Finland, the NASA astronaut Timothy Kopra, a Finnish American, has sometimes been referred to as sisunautti, from the Finnish word sisu. == Space travel milestones == The first human in space was Soviet Yuri Gagarin, who was launched on April 12, 1961, aboard Vostok 1 and orbited around the Earth for 108 minutes. The first woman in space was Soviet Valentina Tereshkova, who launched on June 16, 1963, aboard Vostok 6 and orbited Earth for almost three days. Alan Shepard became the first American and second person in space on May 5, 1961, on a 15-minute sub-orbital flight. The first American to orbit the Earth was John Glenn, aboard Friendship 7 on February 20, 1962. The first American woman in space was Sally Ride, during Space Shuttle Challenger's mission STS-7, on June 18, 1983. In 1992 Mae Jemison became the first African American woman to travel in space aboard STS-47. Cosmonaut Alexei Leonov was the first person to conduct an extravehicular activity (EVA), (commonly called a "spacewalk"), on March 18, 1965, on the Soviet Union's Voskhod 2 mission. This was followed two and a half months later by astronaut Ed White who made the first American EVA on NASA's Gemini 4 mission.The first manned mission to orbit the Moon, Apollo 8, included American William Anders who was born in Hong Kong, making him the first Asian-born astronaut in 1968. The Soviet Union, through its Intercosmos program, allowed people from other "socialist" (i.e. Warsaw Pact and other Soviet-allied) countries to fly on its missions, with the notable exception of France participating in Soyuz TM-7. An example is Czechoslovak Vladimír Remek, the first cosmonaut from a country other than the Soviet Union or the United States, who flew to space in 1978 on a Soyuz-U rocket.On July 23, 1980, Pham Tuan of Vietnam became the first Asian in space when he flew aboard Soyuz 37. Also in 1980, Cuban Arnaldo Tamayo Méndez became the first person of Hispanic and black African descent to fly in space, and in 1983, Guion Bluford became the first African American to fly into space. In April 1985, Taylor Wang became the first ethnic Chinese person in space. The first person born in Africa to fly in space was Patrick Baudry (France), in 1985. In 1985, Saudi Arabian Prince Sultan Bin Salman Bin AbdulAziz Al-Saud became the first Arab Muslim astronaut in space. In 1988, Abdul Ahad Mohmand became the first Afghan to reach space, spending nine days aboard the Mir space station.With the increase of seats on the Space Shuttle, the U.S. began taking international astronauts. In 1983, Ulf Merbold of West Germany became the first non-US citizen to fly in a US spacecraft. In 1984, Marc Garneau became the first of 8 Canadian astronauts to fly in space (through 2010). In 1985, Rodolfo Neri Vela became the first Mexican-born person in space. In 1991, Helen Sharman became the first Briton to fly in space. In 2002, Mark Shuttleworth became the first citizen of an African country to fly in space, as a paying spaceflight participant. In 2003, Ilan Ramon became the first Israeli to fly in space, although he died during a re-entry accident. On October 15, 2003, Yang Liwei became China's first astronaut on the Shenzhou 5 spacecraft. === Age milestones === The youngest person to fly in space is Gherman Titov, who was 25 years old when he flew Vostok 2. (Titov was also the first person to suffer space sickness). The oldest person who has flown in space is John Glenn, who was 77 when he flew on STS-95. === Duration and distance milestones === 438 days is the longest time spent in space, by Russian Valeri Polyakov. As of 2006, the most spaceflights by an individual astronaut is seven, a record held by both Jerry L. Ross and Franklin Chang-Diaz. The farthest distance from Earth an astronaut has traveled was 401,056 km (249,205 mi), when Jim Lovell, Jack Swigert, and Fred Haise went around the Moon during the Apollo 13 emergency. === Civilian and non-government milestones === The first civilian in space was Valentina Tereshkova aboard Vostok 6 (she also became the first woman in space on that mission). Tereshkova was only honorarily inducted into the USSR's Air Force, which did not accept female pilots at that time. A month later, Joseph Albert Walker became the first American civilian in space when his X-15 Flight 90 crossed the 100 kilometers (54 nautical miles) line, qualifying him by the international definition of spaceflight. Walker had joined the US Army Air Force but was not a member during his flight. The first people in space who had never been a member of any country's armed forces were both Konstantin Feoktistov and Boris Yegorov aboard Voskhod 1. The first non-governmental space traveler was Byron K. Lichtenberg, a researcher from the Massachusetts Institute of Technology who flew on STS-9 in 1983. In December 1990, Toyohiro Akiyama became the first paying space traveler as a reporter for Tokyo Broadcasting System, a visit to Mir as part of an estimated $12 million (USD) deal with a Japanese TV station, although at the time, the term used to refer to Akiyama was "Research Cosmonaut". Akiyama suffered severe space sickness during his mission, which affected his productivity.The first self-funded space tourist was Dennis Tito on board the Russian spacecraft Soyuz TM-3 on April 28, 2001. === Self-funded travelers === The first person to fly on an entirely privately funded mission was Mike Melvill, piloting SpaceShipOne flight 15P on a suborbital journey, although he was a test pilot employed by Scaled Composites and not an actual paying space tourist. Seven others have paid the Russian Space Agency to fly into space: Dennis Tito (American): April 28 – May 6, 2001 (ISS) Mark Shuttleworth (South African): April 25 – May 5, 2002 (ISS) Gregory Olsen (American): October 1–11, 2005 (ISS) Anousheh Ansari (Iranian / American): September 18–29, 2006 (ISS) Charles Simonyi (Hungarian / American): April 7–21, 2007 (ISS), March 26 – April 8, 2009 (ISS) Richard Garriott (British / American): October 12–24, 2008 (ISS) Guy Laliberté (Canadian): September 30, 2009 – October 11, 2009 (ISS) == Training == The first NASA astronauts were selected for training in 1959. Early in the space program, military jet test piloting and engineering training were often cited as prerequisites for selection as an astronaut at NASA, although neither John Glenn nor Scott Carpenter (of the Mercury Seven) had any university degree, in engineering or any other discipline at the time of their selection. Selection was initially limited to military pilots. The earliest astronauts for both America and the USSR tended to be jet fighter pilots, and were often test pilots. Once selected, NASA astronauts go through twenty months of training in a variety of areas, including training for extravehicular activity in a facility such as NASA's Neutral Buoyancy Laboratory. Astronauts-in-training (astronaut candidates) may also experience short periods of weightlessness (microgravity) in an aircraft called the "Vomit Comet," the nickname given to a pair of modified KC-135s (retired in 2000 and 2004, respectively, and replaced in 2005 with a C-9) which perform parabolic flights. Astronauts are also required to accumulate a number of flight hours in high-performance jet aircraft. This is mostly done in T-38 jet aircraft out of Ellington Field, due to its proximity to the Johnson Space Center. Ellington Field is also where the Shuttle Training Aircraft is maintained and developed, although most flights of the aircraft are conducted from Edwards Air Force Base. Astronauts is training must learn how to control and fly the Space Shuttle and, it is vital that they are familiar with the International Space Station so they know what they must do when they get there. === NASA candidacy requirements === Be citizens of the United States. Pass a strict physical examination, and have a near and distant visual acuity correctable to 20/20 (6/6). Blood pressure, while sitting, must be no greater than 140 over 90. There are currently no age restrictions. ==== Commander and Pilot ==== A bachelor's degree in engineering, biological science, physical science or mathematics is required. At least 1,000 hours' flying time as pilot-in-command in jet aircraft. Experience as a test pilot is desirable. Height must be 5 ft 2 in to 6 ft 2 in (1.58 m to 1.88 m). Distant visual acuity must be correctable to 20/20 in each eye. The refractive surgical procedures of the eye, PRK (Photorefractive keratectomy) and LASIK, are now allowed, providing at least 1 year has passed since the date of the procedure with no permanent adverse after effects. For those applicants under final consideration, an operative report on the surgical procedure will be requested. ==== Mission Specialist ==== A bachelor's degree in engineering, biological science, physical science or mathematics, as well as at least three years of related professional experience (graduate work or studies) and an advanced degree, such as a master's degree (one to three years) or a doctoral degree (three years or more). Applicant's height must be between 4 ft 10.5 in and 6 ft 4 in (1.49 m and 1.93 m). ==== Mission Specialist Educator ==== Applicants must have a bachelor's degree with teaching experience, including work at the kindergarten through twelfth grade level. An advanced degree, such as a master's degree or a doctoral degree, is not required, but is strongly desired.Mission Specialist Educators, or "Educator Astronauts", were first selected in 2004, and as of 2007, there are three NASA Educator astronauts: Joseph M. Acaba, Richard R. Arnold, and Dorothy Metcalf-Lindenburger.Barbara Morgan, selected as back-up teacher to Christa McAuliffe in 1985, is considered to be the first Educator astronaut by the media, but she trained as a mission specialist. The Educator Astronaut program is a successor to the Teacher in Space program from the 1980s. == Health risks of space travel == Astronauts are susceptible to a variety of health risks including decompression sickness, barotrauma, immunodeficiencies, loss of bone and muscle, loss of eyesight, orthostatic intolerance, sleep disturbances, and radiation injury. A variety of large scale medical studies are being conducted in space via the National Space and Biomedical Research Institute (NSBRI) to address these issues. Prominent among these is the Advanced Diagnostic Ultrasound in Microgravity Study in which astronauts (including former ISS commanders Leroy Chiao and Gennady Padalka) perform ultrasound scans under the guidance of remote experts to diagnose and potentially treat hundreds of medical conditions in space. This study's techniques are now being applied to cover professional and Olympic sports injuries as well as ultrasound performed by non-expert operators in medical and high school students. It is anticipated that remote guided ultrasound will have application on Earth in emergency and rural care situations, where access to a trained physician is often rare.A 2006 Space Shuttle experiment found that Salmonella typhimurium, a bacterium that can cause food poisoning, became more virulent when cultivated in space. More recently, in 2017, bacteria were found to be more resistant to antibiotics and to thrive in the near-weightlessness of space. Microorganisms have been observed to survive the vacuum of outer space.On December 31, 2012, a NASA-supported study reported that manned spaceflight may harm the brain and accelerate the onset of Alzheimer's disease.In October 2015, the NASA Office of Inspector General issued a health hazards report related to space exploration, including a human mission to Mars.Over the last decade, flight surgeons and scientists at NASA have seen a pattern of vision problems in astronauts on long-duration space missions. The syndrome, known as visual impairment intracranial pressure (VIIP), has been reported in nearly two-thirds of space explorers after long periods spent aboard the International Space Station (ISS). On November 2, 2017, scientists reported that significant changes in the position and structure of the brain have been found in astronauts who have taken trips in space, based on MRI studies. Astronauts who took longer space trips were associated with greater brain changes. Being in space can be physiologically deconditioning on the body. It can affect the otolith organs and adaptive capabilities of the central nervous system. Zero gravity and cosmic rays can cause many implications for astronauts. == Food and drink == An astronaut on the International Space Station requires about 0.83 kilograms (1.83 pounds) weight of food inclusive of food packaging per meal each day. (The packaging for each meal weighs around 0.12 kilograms - 0.27 pounds) Longer-duration missions require more food. Shuttle astronauts worked with nutritionists to select menus that appeal to their individual tastes. Five months before flight, menus are selected and analyzed for nutritional content by the shuttle dietician. Foods are tested to see how they will react in a reduced gravity environment. Caloric requirements are determined using a basal energy expenditure (BEE) formula. On Earth, the average American uses about 35 gallons (132 liters) of water every day. On board the ISS astronauts limit water use to only about three gallons (11 liters) per day. == Insignia == In Russia, cosmonauts are awarded Pilot-Cosmonaut of the Russian Federation upon completion of their missions, often accompanied with the award of Hero of the Russian Federation. This follows the practice established in the USSR where cosmonauts were usually awarded the title Hero of the Soviet Union. At NASA, those who complete astronaut candidate training receive a silver lapel pin. Once they have flown in space, they receive a gold pin. U.S. astronauts who also have active-duty military status receive a special qualification badge, known as the Astronaut Badge, after participation on a spaceflight. The United States Air Force also presents an Astronaut Badge to its pilots who exceed 50 miles (80 km) in altitude. == Deaths == Eighteen astronauts (fourteen men and four women) have lost their lives during four space flights. By nationality, thirteen were American (including one born in India), four were Russian (Soviet Union), and one was Israeli. Eleven people (all men) have lost their lives training for spaceflight: eight Americans and three Russians. Six of these were in crashes of training jet aircraft, one drowned during water recovery training, and four were due to fires in pure oxygen environments. The Space Mirror Memorial, which stands on the grounds of the John F. Kennedy Space Center Visitor Complex, commemorates the lives of the men and women who have died during spaceflight and during training in the space programs of the United States. In addition to twenty NASA career astronauts, the memorial includes the names of a U.S. Air Force X-15 test pilot, a U.S. Air Force officer who died while training for a then-classified military space program, and a civilian spaceflight participant. == See also == == References == == External links == https://www.nasa.gov/hrp/bodyinspace NASA: How to become an astronaut 101 List of International partnership organizations Encyclopedia Astronautica: Phantom cosmonauts collectSPACE: Astronaut appearances calendar spacefacts Spacefacts.de Manned astronautics: facts and figures Astronaut Candidate Brochure online ### Answer: <Astronauts>, <Science occupations>

### Instruction: retrieve labels for this: A Modest Proposal For preventing the Children of Poor People From being a Burthen to Their Parents or Country, and For making them Beneficial to the Publick, commonly referred to as A Modest Proposal, is a Juvenalian satirical essay written and published anonymously by Jonathan Swift in 1729. The essay suggests that the impoverished Irish might ease their economic troubles by selling their children as food for rich gentlemen and ladies. This satirical hyperbole mocked heartless attitudes towards the poor, as well as British policy toward the Irish in general. The primary target of Swift's satire was the rationalism of modern economics, and the growth of rationalistic modes of thinking in modern life at the expense of more traditional human values. In English writing, the phrase "a modest proposal" is now conventionally an allusion to this style of straight-faced satire. == Synopsis == This essay is widely held to be one of the greatest examples of sustained irony in the history of the English language. Much of its shock value derives from the fact that the first portion of the essay describes the plight of starving beggars in Ireland, so that the reader is unprepared for the surprise of Swift's solution when he states: "A young healthy child well nursed, is, at a year old, a most delicious nourishing and wholesome food, whether stewed, roasted, baked, or boiled; and I make no doubt that it will equally serve in a fricassee, or a ragout."Swift goes to great lengths to support his argument, including a list of possible preparation styles for the children, and calculations showing the financial benefits of his suggestion. He uses methods of argument throughout his essay which lampoon the then-influential William Petty and the social engineering popular among followers of Francis Bacon. These lampoons include appealing to the authority of "a very knowing American of my acquaintance in London" and "the famous Psalmanazar, a native of the island Formosa" (who had already confessed to not being from Formosa in 1706). In the tradition of Roman satire, Swift introduces the reforms he is actually suggesting by paralipsis: Therefore let no man talk to me of other expedients: Of taxing our absentees at five shillings a pound: Of using neither clothes, nor household furniture, except what is of our own growth and manufacture: Of utterly rejecting the materials and instruments that promote foreign luxury: Of curing the expensiveness of pride, vanity, idleness, and gaming in our women: Of introducing a vein of parsimony, prudence and temperance: Of learning to love our country, wherein we differ even from Laplanders, and the inhabitants of Topinamboo: Of quitting our animosities and factions, nor acting any longer like the Jews, who were murdering one another at the very moment their city was taken: Of being a little cautious not to sell our country and consciences for nothing: Of teaching landlords to have at least one degree of mercy towards their tenants. Lastly, of putting a spirit of honesty, industry, and skill into our shop-keepers, who, if a resolution could now be taken to buy only our native goods, would immediately unite to cheat and exact upon us in the price, the measure, and the goodness, nor could ever yet be brought to make one fair proposal of just dealing, though often and earnestly invited to it. Therefore I repeat, let no man talk to me of these and the like expedients, 'till he hath at least some glympse of hope, that there will ever be some hearty and sincere attempt to put them into practice. == Population solutions == George Wittkowsky argued that Swift’s main target in A Modest Proposal was not the conditions in Ireland, but rather the can-do spirit of the times that led people to devise a number of illogical schemes that would purportedly solve social and economic ills. Swift was especially attacking projects that tried to fix population and labour issues with a simple cure-all solution. A memorable example of these sorts of schemes "involved the idea of running the poor through a joint-stock company". In response, Swift's Modest Proposal was "a burlesque of projects concerning the poor" that were in vogue during the early 18th century. A Modest Proposal also targets the calculating way people perceived the poor in designing their projects. The pamphlet targets reformers who "regard people as commodities". In the piece, Swift adopts the "technique of a political arithmetician" to show the utter ridiculousness of trying to prove any proposal with dispassionate statistics. Critics differ about Swift's intentions in using this faux-mathematical philosophy. Edmund Wilson argues that statistically "the logic of the 'Modest proposal' can be compared with defence of crime (arrogated to Marx) in which he argues that crime takes care of the superfluous population". Wittkowsky counters that Swift's satiric use of statistical analysis is an effort to enhance his satire that "springs from a spirit of bitter mockery, not from the delight in calculations for their own sake". == Rhetoric == Charles K. Smith argues that Swift's rhetorical style persuades the reader to detest the speaker and pity the Irish. Swift's specific strategy is twofold, using a "trap" to create sympathy for the Irish and a dislike of the narrator who, in the span of one sentence, "details vividly and with rhetorical emphasis the grinding poverty" but feels emotion solely for members of his own class. Swift's use of gripping details of poverty and his narrator's cool approach towards them create "two opposing points of view" that "alienate the reader, perhaps unconsciously, from a narrator who can view with 'melancholy' detachment a subject that Swift has directed us, rhetorically, to see in a much less detached way."Swift has his proposer further degrade the Irish by using language ordinarily reserved for animals. Lewis argues that the speaker uses "the vocabulary of animal husbandry" to describe the Irish. Once the children have been commodified, Swift's rhetoric can easily turn "people into animals, then meat, and from meat, logically, into tonnage worth a price per pound".Swift uses the proposer's serious tone to highlight the absurdity of his proposal. In making his argument, the speaker uses the conventional, textbook-approved order of argument from Swift's time (which was derived from the Latin rhetorician Quintilian). The contrast between the "careful control against the almost inconceivable perversion of his scheme" and "the ridiculousness of the proposal" create a situation in which the reader has "to consider just what perverted values and assumptions would allow such a diligent, thoughtful, and conventional man to propose so perverse a plan". == Influences == Scholars have speculated about which earlier works Swift may have had in mind when he wrote A Modest Proposal. === Tertullian's Apology === James Johnson argued that A Modest Proposal was largely influenced and inspired by Tertullian's Apology: a satirical attack against early Roman persecution of Christianity. James William Johnson believes that Swift saw major similarities between the two situations. Johnson notes Swift's obvious affinity for Tertullian and the bold stylistic and structural similarities between the works A Modest Proposal and Apology. In structure, Johnson points out the same central theme, that of cannibalism and the eating of babies as well as the same final argument, that "human depravity is such that men will attempt to justify their own cruelty by accusing their victims of being lower than human". Stylistically, Swift and Tertullian share the same command of sarcasm and language. In agreement with Johnson, Donald C. Baker points out the similarity between both authors' tones and use of irony. Baker notes the uncanny way that both authors imply an ironic "justification by ownership" over the subject of sacrificing children—Tertullian while attacking pagan parents, and Swift while attacking the English mistreatment of the Irish poor. === Defoe's The Generous Projector === It has also been argued that A Modest Proposal was, at least in part, a response to the 1728 essay The Generous Projector or, A Friendly Proposal to Prevent Murder and Other Enormous Abuses, By Erecting an Hospital for Foundlings and Bastard Children by Swift's rival Daniel Defoe. === Mandeville's Modest Defence of Publick Stews === Bernard Mandeville's Modest Defence of Publick Stews asked to introduce public and state controlled bordellos. The 1726 paper acknowledges women's interests and – while not being a complete satirical text – has also been discussed as an inspiration for Jonathan Swift's title. Mandeville had by 1705 already become famous for the Fable of The Bees and deliberations on private vices and public benefits. === John Locke's First Treatise of Government === Locke commented: "Be it then as Sir Robert says, that Anciently, it was usual for Men to sell and Castrate their Children. Let it be, that they exposed them; Add to it, if you please, for this is still greater Power, that they begat them for their Tables to fat and eat them: If this proves a right to do so, we may, by the same Argument, justifie Adultery, Incest and Sodomy, for there are examples of these too, both Ancient and Modern; Sins, which I suppose, have the Principle Aggravation from this, that they cross the main intention of Nature, which willeth the increase of Mankind, and the continuation of the Species in the highest perfection, and the distinction of Families, with the Security of the Marriage Bed, as necessary thereunto". (First Treatise, sec. 59). == Economic themes == Robert Phiddian's article "Have you eaten yet? The Reader in A Modest Proposal" focuses on two aspects of A Modest Proposal: the voice of Swift and the voice of the Proposer. Phiddian stresses that a reader of the pamphlet must learn to distinguish between the satirical voice of Jonathan Swift and the apparent economic projections of the Proposer. He reminds readers that "there is a gap between the narrator's meaning and the text's, and that a moral-political argument is being carried out by means of parody".While Swift's proposal is obviously not a serious economic proposal, George Wittkowsky, author of "Swift's Modest Proposal: The Biography of an Early Georgian Pamphlet", argues that to understand the piece fully it is important to understand the economics of Swift’s time. Wittowsky argues that not enough critics have taken the time to focus directly on the mercantilism and theories of labour in 18th century England. "[I]f one regards the Modest Proposal simply as a criticism of condition, about all one can say is that conditions were bad and that Swift's irony brilliantly underscored this fact". === "People are the riches of a nation" === At the start of a new industrial age in the 18th century, it was believed that "people are the riches of the nation", and there was a general faith in an economy that paid its workers low wages because high wages meant workers would work less. Furthermore, "in the mercantilist view no child was too young to go into industry". In those times, the "somewhat more humane attitudes of an earlier day had all but disappeared and the laborer had come to be regarded as a commodity".Landa composed a conducive analysis when he noted that it would have been healthier for the Irish economy to more appropriately utilize their human assets by giving the people an opportunity to “become a source of wealth to the nation” or else they “must turn to begging and thievery” . This opportunity may have included giving the farmers more coin to work for, diversifying their professions, or even consider enslaving their people to lower coin usage and build up financial stock in Ireland. Landa wrote that, "Swift is maintaining that the maxim—people are the riches of a nation—applies to Ireland only if Ireland is permitted slavery or cannibalism" Louis A. Landa presents Swift's A Modest Proposal as a critique of the popular and unjustified maxim of mercantilism in the 18th century that "people are the riches of a nation". Swift presents the dire state of Ireland and shows that mere population itself, in Ireland's case, did not always mean greater wealth and economy. The uncontrolled maxim fails to take into account that a person who does not produce in an economic or political way makes a country poorer, not richer. Swift also recognises the implications of this fact in making mercantilist philosophy a paradox: the wealth of a country is based on the poverty of the majority of its citizens. Swift however, Landa argues, is not merely criticising economic maxims but also addressing the fact that England was denying Irish citizens their natural rights and dehumanising them by viewing them as a mere commodity. == The public's reaction == Swift's writings created a backlash within the community after its publication. The work was aimed at the aristocracy, and they responded in turn. Several members of society wrote to Swift regarding the work. Lord Bathurst's letter intimated that he certainly understood the message, and interpreted it as a work of comedy: February 12, 1729-30:"I did immediately propose it to Lady Bathurst, as your advice, particularly for her last boy, which was born the plumpest, finest thing, that could be seen; but she fell in a passion, and bid me send you word, that she would not follow your direction, but that she would breed him up to be a parson, and he should live upon the fat of the land; or a lawyer, and then, instead of being eat himself, he should devour others. You know women in passion never mind what they say; but, as she is a very reasonable woman, I have almost brought her over now to your opinion; and having convinced her, that as matters stood, we could not possibly maintain all the nine, she does begin to think it reasonable the youngest should raise fortunes for the eldest: and upon that foot a man may perforin family duty with more courage and zeal; for, if he should happen to get twins, the selling of one might provide for the other. Or if, by any accident, while his wife lies in with one child, he should get a second upon the body of another woman, he might dispose of the fattest of the two, and that would help to breed up the other.The more I think upon this scheme, the more reasonable it appears to me; and it ought by no means to be confined to Ireland; for, in all probability, we shall, in a very little time, be altogether as poor here as you are there. I believe, indeed, we shall carry it farther, and not confine our luxury only to the eating of children; for I happened to peep the other day into a large assembly [Parliament] not far from Westminster-hall, and I found them roasting a great fat fellow, [Walpole again] For my own part, I had not the least inclination to a slice of him; but, if I guessed right, four or five of the company had a devilish mind to be at him. Well, adieu, you begin now to wish I had ended, when I might have done it so conveniently". == Modern usage == A Modest Proposal is included in many literature courses as an example of early modern western satire. It also serves as an exceptional introduction to the concept and use of argumentative language, lending itself well to secondary and post-secondary essay courses. Outside of the realm of English studies, A Modest Proposal is included in many comparative and global literature and history courses, as well as those of numerous other disciplines in the arts, humanities, and even the social sciences. The essay's approach has been copied many times. In his book A Modest Proposal (1984), the evangelical author Frank Schaeffer emulated Swift's work in a social conservative polemic against abortion and euthanasia, imagining a future dystopia that advocates recycling of aborted embryos, fetuses, and some disabled infants with compound intellectual, physical and physiological difficulties. (Such Baby Doe Rules cases were then a major concern of the US pro-life movement of the early 1980s, which viewed selective treatment of those infants as disability discrimination). In his book A Modest Proposal for America (2013), statistician Howard Friedman opens with a satirical reflection of the extreme drive to fiscal stability by ultra-conservatives. In the 1998 edition of "A Handmaid's Tale" by Margaret Atwood there is a quote from "A Modest Proposal" before the introduction."A Modest Video Game Proposal" is the title of an open letter sent by activist/former attorney Jack Thompson on 10 October 2005. He proposed that someone should "create, manufacture, distribute, and sell a video game" that would allow players to act out a scenario in which the game character kills video game developers.[1]Hunter S. Thompson's Fear and Loathing in America: The Brutal Odyssey of an Outlaw Journalist includes a letter in which he uses Swift's approach in connection with the Vietnam War. Thompson writes a letter to a local Aspen newspaper informing them that, on Christmas Eve, he was going to use napalm to burn a number of dogs and hopefully any humans they find. The letter protests against the burning of Vietnamese people occurring overseas.The 2012 film Butcher Boys, written by Kim Henkel, is said to be loosely based on Jonathan Swift's A Modest Proposal. The film's opening scene takes place in a restaurant named "J. Swift's". On November 30, 2017, Jonathan Swift's 350th birthday, The Washington Post published a column entitled "Why Alabamians should consider eating Democrats’ babies", by the humorous columnist Alexandra Petri. == Notes == == References == Baker, Donald C (1957), "Tertullian and Swift's A Modest Proposal", The Classical Journal, 52: 219–220 Johnson, James William (1958), "Tertullian and A Modest Proposal", Modern Language and Notes, The Johns Hopkins University Press, 73 (8): 561–563, doi:10.2307/3043246, JSTOR 3043246 (subscription needed) Landa, Louis A (1942), "A Modest Proposal and Populousness", Modern Philology, 40 (2): 161–170, doi:10.1086/388567 Phiddian, Robert (1996), "Have You Eaten Yet?

### Instruction: retrieve labels for this: The atomic number or proton number (symbol Z) of a chemical element is the number of protons found in the nucleus of an atom. It is identical to the charge number of the nucleus. The atomic number uniquely identifies a chemical element. In an uncharged atom, the atomic number is also equal to the number of electrons. The sum of the atomic number Z and the number of neutrons, N, gives the mass number A of an atom. Since protons and neutrons have approximately the same mass (and the mass of the electrons is negligible for many purposes) and the mass defect of nucleon binding is always small compared to the nucleon mass, the atomic mass of any atom, when expressed in unified atomic mass units (making a quantity called the "relative isotopic mass"), is within 1% of the whole number A. Atoms with the same atomic number Z but different neutron numbers N, and hence different atomic masses, are known as isotopes. A little more than three-quarters of naturally occurring elements exist as a mixture of isotopes (see monoisotopic elements), and the average isotopic mass of an isotopic mixture for an element (called the relative atomic mass) in a defined environment on Earth, determines the element's standard atomic weight. Historically, it was these atomic weights of elements (in comparison to hydrogen) that were the quantities measurable by chemists in the 19th century. The conventional symbol Z comes from the German word Zahl meaning number, which, before the modern synthesis of ideas from chemistry and physics, merely denoted an element's numerical place in the periodic table, whose order is approximately, but not completely, consistent with the order of the elements by atomic weights. Only after 1915, with the suggestion and evidence that this Z number was also the nuclear charge and a physical characteristic of atoms, did the word Atomzahl (and its English equivalent atomic number) come into common use in this context. == History == === The periodic table and a natural number for each element === Loosely speaking, the existence or construction of a periodic table of elements creates an ordering of the elements, and so they can be numbered in order. Dmitri Mendeleev claimed that he arranged his first periodic tables (first published on March 6th, 1869) in order of atomic weight ("Atomgewicht"). However, in consideration of the elements' observed chemical properties, he changed the order slightly and placed tellurium (atomic weight 127.6) ahead of iodine (atomic weight 126.9). This placement is consistent with the modern practice of ordering the elements by proton number, Z, but that number was not known or suspected at the time. A simple numbering based on periodic table position was never entirely satisfactory, however. Besides the case of iodine and tellurium, later several other pairs of elements (such as argon and potassium, cobalt and nickel) were known to have nearly identical or reversed atomic weights, thus requiring their placement in the periodic table to be determined by their chemical properties. However the gradual identification of more and more chemically similar lanthanide elements, whose atomic number was not obvious, led to inconsistency and uncertainty in the periodic numbering of elements at least from lutetium (element 71) onwards (hafnium was not known at this time). === The Rutherford-Bohr model and van den Broek === In 1911, Ernest Rutherford gave a model of the atom in which a central core held most of the atom's mass and a positive charge which, in units of the electron's charge, was to be approximately equal to half of the atom's atomic weight, expressed in numbers of hydrogen atoms. This central charge would thus be approximately half the atomic weight (though it was almost 25% different from the atomic number of gold (Z = 79, A = 197), the single element from which Rutherford made his guess). Nevertheless, in spite of Rutherford's estimation that gold had a central charge of about 100 (but was element Z = 79 on the periodic table), a month after Rutherford's paper appeared, Antonius van den Broek first formally suggested that the central charge and number of electrons in an atom was exactly equal to its place in the periodic table (also known as element number, atomic number, and symbolized Z). This proved eventually to be the case. === Moseley's 1913 experiment === The experimental position improved dramatically after research by Henry Moseley in 1913. Moseley, after discussions with Bohr who was at the same lab (and who had used Van den Broek's hypothesis in his Bohr model of the atom), decided to test Van den Broek's and Bohr's hypothesis directly, by seeing if spectral lines emitted from excited atoms fitted the Bohr theory's postulation that the frequency of the spectral lines be proportional to the square of Z. To do this, Moseley measured the wavelengths of the innermost photon transitions (K and L lines) produced by the elements from aluminum (Z = 13) to gold (Z = 79) used as a series of movable anodic targets inside an x-ray tube. The square root of the frequency of these photons (x-rays) increased from one target to the next in an arithmetic progression. This led to the conclusion (Moseley's law) that the atomic number does closely correspond (with an offset of one unit for K-lines, in Moseley's work) to the calculated electric charge of the nucleus, i.e. the element number Z. Among other things, Moseley demonstrated that the lanthanide series (from lanthanum to lutetium inclusive) must have 15 members—no fewer and no more—which was far from obvious from the chemistry at that time. === Missing elements === After Moseley's death in 1915, the atomic numbers of all known elements from hydrogen to uranium (Z = 92) were examined by his method. There were seven elements (with Z < 92) which were not found and therefore identified as still undiscovered, corresponding to atomic numbers 43, 61, 72, 75, 85, 87 and 91. From 1918 to 1947, all seven of these missing elements were discovered. By this time the first four transuranium elements had also been discovered, so that the periodic table was complete with no gaps as far as curium (Z = 96). === The proton and the idea of nuclear electrons === In 1915 the reason for nuclear charge being quantized in units of Z, which were now recognized to be the same as the element number, was not understood. An old idea called Prout's hypothesis had postulated that the elements were all made of residues (or "protyles") of the lightest element hydrogen, which in the Bohr-Rutherford model had a single electron and a nuclear charge of one. However, as early as 1907 Rutherford and Thomas Royds had shown that alpha particles, which had a charge of +2, were the nuclei of helium atoms, which had a mass four times that of hydrogen, not two times. If Prout's hypothesis were true, something had to be neutralizing some of the charge of the hydrogen nuclei present in the nuclei of heavier atoms. In 1917 Rutherford succeeded in generating hydrogen nuclei from a nuclear reaction between alpha particles and nitrogen gas, and believed he had proven Prout's law. He called the new heavy nuclear particles protons in 1920 (alternate names being proutons and protyles). It had been immediately apparent from the work of Moseley that the nuclei of heavy atoms have more than twice as much mass as would be expected from their being made of hydrogen nuclei, and thus there was required a hypothesis for the neutralization of the extra protons presumed present in all heavy nuclei. A helium nucleus was presumed to be composed of four protons plus two "nuclear electrons" (electrons bound inside the nucleus) to cancel two of the charges. At the other end of the periodic table, a nucleus of gold with a mass 197 times that of hydrogen, was thought to contain 118 nuclear electrons in the nucleus to give it a residual charge of + 79, consistent with its atomic number. === The discovery of the neutron makes Z the proton number === All consideration of nuclear electrons ended with James Chadwick's discovery of the neutron in 1932. An atom of gold now was seen as containing 118 neutrons rather than 118 nuclear electrons, and its positive charge now was realized to come entirely from a content of 79 protons. After 1932, therefore, an element's atomic number Z was also realized to be identical to the proton number of its nuclei. == The symbol of Z == The conventional symbol Z possibly comes from the German word Atomzahl (atomic number). However, prior to 1915, the word Zahl (simply number) was used for an element's assigned number in the periodic table. == Chemical properties == Each element has a specific set of chemical properties as a consequence of the number of electrons present in the neutral atom, which is Z (the atomic number). The configuration of these electrons follows from the principles of quantum mechanics. The number of electrons in each element's electron shells, particularly the outermost valence shell, is the primary factor in determining its chemical bonding behavior. Hence, it is the atomic number alone that determines the chemical properties of an element; and it is for this reason that an element can be defined as consisting of any mixture of atoms with a given atomic number. == New elements == The quest for new elements is usually described using atomic numbers. As of 2010, all elements with atomic numbers 1 to 118 have been observed. Synthesis of new elements is accomplished by bombarding target atoms of heavy elements with ions, such that the sum of the atomic numbers of the target and ion elements equals the atomic number of the element being created.

Anatomy is a branch of natural science which deals with the structural organization of living things. It is an old science, having its beginnings in prehistoric times. Anatomy is inherently tied to embryology, comparative anatomy, evolutionary biology, and phylogeny, as these are the processes by which anatomy is generated over immediate (embryology) and long (evolution) timescales. Human anatomy is one of the basic essential sciences of medicine. Anatomy and physiology, which study (respectively) the structure and function of organisms and their parts, make a natural pair of related disciplines, and they are often studied together. The discipline of anatomy is divided into macroscopic and microscopic anatomy. Macroscopic anatomy, or gross anatomy, is the examination of an animal's body parts using unaided eyesight. Gross anatomy also includes the branch of superficial anatomy. Microscopic anatomy involves the use of optical instruments in the study of the tissues of various structures, known as histology, and also in the study of cells. The history of anatomy is characterized by a progressive understanding of the functions of the organs and structures of the human body. Methods have also improved dramatically, advancing from the examination of animals by dissection of carcasses and cadavers (corpses) to 20th century medical imaging techniques including X-ray, ultrasound, and magnetic resonance imaging. == Definition == Derived from the Greek ἀνατομή anatomē "dissection" (from ἀνατέμνω anatémnō "I cut up, cut open" from ἀνά aná "up", and τέμνω témnō "I cut"), anatomy is the scientific study of the structure of organisms including their systems, organs and tissues. It includes the appearance and position of the various parts, the materials from which they are composed, their locations and their relationships with other parts. Anatomy is quite distinct from physiology and biochemistry, which deal respectively with the functions of those parts and the chemical processes involved. For example, an anatomist is concerned with the shape, size, position, structure, blood supply and innervation of an organ such as the liver; while a physiologist is interested in the production of bile, the role of the liver in nutrition and the regulation of bodily functions.The discipline of anatomy can be subdivided into a number of branches including gross or macroscopic anatomy and microscopic anatomy. Gross anatomy is the study of structures large enough to be seen with the naked eye, and also includes superficial anatomy or surface anatomy, the study by sight of the external body features. Microscopic anatomy is the study of structures on a microscopic scale, including histology (the study of tissues), and embryology (the study of an organism in its immature condition).Anatomy can be studied using both invasive and non-invasive methods with the goal of obtaining information about the structure and organization of organs and systems. Methods used include dissection, in which a body is opened and its organs studied, and endoscopy, in which a video camera-equipped instrument is inserted through a small incision in the body wall and used to explore the internal organs and other structures. Angiography using X-rays or magnetic resonance angiography are methods to visualize blood vessels.The term "anatomy" is commonly taken to refer to human anatomy. However, substantially the same structures and tissues are found throughout the rest of the animal kingdom and the term also includes the anatomy of other animals. The term zootomy is also sometimes used to specifically refer to animals. The structure and tissues of plants are of a dissimilar nature and they are studied in plant anatomy. == Animal tissues == The kingdom Animalia contains multicellular organisms that are heterotrophic and motile (although some have secondarily adopted a sessile lifestyle). Most animals have bodies differentiated into separate tissues and these animals are also known as eumetazoans. They have an internal digestive chamber, with one or two openings; the gametes are produced in multicellular sex organs, and the zygotes include a blastula stage in their embryonic development. Metazoans do not include the sponges, which have undifferentiated cells.Unlike plant cells, animal cells have neither a cell wall nor chloroplasts. Vacuoles, when present, are more in number and much smaller than those in the plant cell. The body tissues are composed of numerous types of cell, including those found in muscles, nerves and skin. Each typically has a cell membrane formed of phospholipids, cytoplasm and a nucleus. All of the different cells of an animal are derived from the embryonic germ layers. Those simpler invertebrates which are formed from two germ layers of ectoderm and endoderm are called diploblastic and the more developed animals whose structures and organs are formed from three germ layers are called triploblastic. All of a triploblastic animal's tissues and organs are derived from the three germ layers of the embryo, the ectoderm, mesoderm and endoderm. Animal tissues can be grouped into four basic types: connective, epithelial, muscle and nervous tissue. === Connective tissue === Connective tissues are fibrous and made up of cells scattered among inorganic material called the extracellular matrix. Connective tissue gives shape to organs and holds them in place. The main types are loose connective tissue, adipose tissue, fibrous connective tissue, cartilage and bone. The extracellular matrix contains proteins, the chief and most abundant of which is collagen. Collagen plays a major part in organizing and maintaining tissues. The matrix can be modified to form a skeleton to support or protect the body. An exoskeleton is a thickened, rigid cuticle which is stiffened by mineralization, as in crustaceans or by the cross-linking of its proteins as in insects. An endoskeleton is internal and present in all developed animals, as well as in many of those less developed. === Epithelium === Epithelial tissue is composed of closely packed cells, bound to each other by cell adhesion molecules, with little intercellular space. Epithelial cells can be squamous (flat), cuboidal or columnar and rest on a basal lamina, the upper layer of the basement membrane, the lower layer is the reticular lamina lying next to the connective tissue in the extracellular matrix secreted by the epithelial cells. There are many different types of epithelium, modified to suit a particular function. In the respiratory tract there is a type of ciliated epithelial lining; in the small intestine there are microvilli on the epithelial lining and in the large intestine there are intestinal villi. Skin consists of an outer layer of keratinized stratified squamous epithelium that covers the exterior of the vertebrate body. Keratinocytes make up to 95% of the cells in the skin. The epithelial cells on the external surface of the body typically secrete an extracellular matrix in the form of a cuticle. In simple animals this may just be a coat of glycoproteins. In more advanced animals, many glands are formed of epithelial cells. === Muscle tissue === Muscle cells (myocytes) form the active contractile tissue of the body. Muscle tissue functions to produce force and cause motion, either locomotion or movement within internal organs. Muscle is formed of contractile filaments and is separated into three main types; smooth muscle, skeletal muscle and cardiac muscle. Smooth muscle has no striations when examined microscopically. It contracts slowly but maintains contractibility over a wide range of stretch lengths. It is found in such organs as sea anemone tentacles and the body wall of sea cucumbers. Skeletal muscle contracts rapidly but has a limited range of extension. It is found in the movement of appendages and jaws. Obliquely striated muscle is intermediate between the other two. The filaments are staggered and this is the type of muscle found in earthworms that can extend slowly or make rapid contractions. In higher animals striated muscles occur in bundles attached to bone to provide movement and are often arranged in antagonistic sets. Smooth muscle is found in the walls of the uterus, bladder, intestines, stomach, oesophagus, respiratory airways, and blood vessels. Cardiac muscle is found only in the heart, allowing it to contract and pump blood round the body. === Nervous tissue === Nervous tissue is composed of many nerve cells known as neurons which transmit information. In some slow-moving radially symmetrical marine animals such as ctenophores and cnidarians (including sea anemones and jellyfish), the nerves form a nerve net, but in most animals they are organized longitudinally into bundles. In simple animals, receptor neurons in the body wall cause a local reaction to a stimulus. In more complex animals, specialized receptor cells such as chemoreceptors and photoreceptors are found in groups and send messages along neural networks to other parts of the organism. Neurons can be connected together in ganglia. In higher animals, specialized receptors are the basis of sense organs and there is a central nervous system (brain and spinal cord) and a peripheral nervous system. The latter consists of sensory nerves that transmit information from sense organs and motor nerves that influence target organs. The peripheral nervous system is divided into the somatic nervous system which conveys sensation and controls voluntary muscle, and the autonomic nervous system which involuntarily controls smooth muscle, certain glands and internal organs, including the stomach. == Vertebrate anatomy == All vertebrates have a similar basic body plan and at some point in their lives, mostly in the embryonic stage, share the major chordate characteristics; a stiffening rod, the notochord; a dorsal hollow tube of nervous material, the neural tube; pharyngeal arches; and a tail posterior to the anus. The spinal cord is protected by the vertebral column and is above the notochord and the gastrointestinal tract is below it. Nervous tissue is derived from the ectoderm, connective tissues are derived from mesoderm, and gut is derived from the endoderm. At the posterior end is a tail which continues the spinal cord and vertebrae but not the gut. The mouth is found at the anterior end of the animal, and the anus at the base of the tail. The defining characteristic of a vertebrate is the vertebral column, formed in the development of the segmented series of vertebrae. In most vertebrates the notochord becomes the nucleus pulposus of the intervertebral discs. However, a few vertebrates, such as the sturgeon and the coelacanth retain the notochord into adulthood. Jawed vertebrates are typified by paired appendages, fins or legs, which may be secondarily lost. The limbs of vertebrates are considered to be homologous because the same underlying skeletal structure was inherited from their last common ancestor. This is one of the arguments put forward by Charles Darwin to support his theory of evolution. === Fish anatomy === The body of a fish is divided into a head, trunk and tail, although the divisions between the three are not always externally visible. The skeleton, which forms the support structure inside the fish, is either made of cartilage, in cartilaginous fish, or bone in bony fish. The main skeletal element is the vertebral column, composed of articulating vertebrae which are lightweight yet strong. The ribs attach to the spine and there are no limbs or limb girdles. The main external features of the fish, the fins, are composed of either bony or soft spines called rays, which with the exception of the caudal fins, have no direct connection with the spine. They are supported by the muscles which compose the main part of the trunk. The heart has two chambers and pumps the blood through the respiratory surfaces of the gills and on round the body in a single circulatory loop. The eyes are adapted for seeing underwater and have only local vision. There is an inner ear but no external or middle ear. Low frequency vibrations are detected by the lateral line system of sense organs that run along the length of the sides of fish, and these respond to nearby movements and to changes in water pressure.Sharks and rays are basal fish with numerous primitive anatomical features similar to those of ancient fish, including skeletons composed of cartilage. Their bodies tend to be dorso-ventrally flattened, they usually have five pairs of gill slits and a large mouth set on the underside of the head. The dermis is covered with separate dermal placoid scales. They have a cloaca into which the urinary and genital passages open, but not a swim bladder. Cartilaginous fish produce a small number of large, yolky eggs. Some species are ovoviviparous and the young develop internally but others are oviparous and the larvae develop externally in egg cases.The bony fish lineage shows more derived anatomical traits, often with major evolutionary changes from the features of ancient fish. They have a bony skeleton, are generally laterally flattened, have five pairs of gills protected by an operculum, and a mouth at or near the tip of the snout. The dermis is covered with overlapping scales. Bony fish have a swim bladder which helps them maintain a constant depth in the water column, but not a cloaca. They mostly spawn a large number of small eggs with little yolk which they broadcast into the water column. === Amphibian anatomy === Amphibians are a class of animals comprising frogs, salamanders and caecilians. They are tetrapods, but the caecilians and a few species of salamander have either no limbs or their limbs are much reduced in size. Their main bones are hollow and lightweight and are fully ossified and the vertebrae interlock with each other and have articular processes. Their ribs are usually short and may be fused to the vertebrae. Their skulls are mostly broad and short, and are often incompletely ossified. Their skin contains little keratin and lacks scales, but contains many mucous glands and in some species, poison glands. The hearts of amphibians have three chambers, two atria and one ventricle. They have a urinary bladder and nitrogenous waste products are excreted primarily as urea. Amphibians breathe by means of buccal pumping, a pump action in which air is first drawn into the buccopharyngeal region through the nostrils. These are then closed and the air is forced into the lungs by contraction of the throat. They supplement this with gas exchange through the skin which needs to be kept moist.In frogs the pelvic girdle is robust and the hind legs are much longer and stronger than the forelimbs. The feet have four or five digits and the toes are often webbed for swimming or have suction pads for climbing. Frogs have large eyes and no tail. Salamanders resemble lizards in appearance; their short legs project sideways, the belly is close to or in contact with the ground and they have a long tail. Caecilians superficially resemble earthworms and are limbless. They burrow by means of zones of muscle contractions which move along the body and they swim by undulating their body from side to side. === Reptile anatomy === Reptiles are a class of animals comprising turtles, tuataras, lizards, snakes and crocodiles. They are tetrapods, but the snakes and a few species of lizard either have no limbs or their limbs are much reduced in size. Their bones are better ossified and their skeletons stronger than those of amphibians. The teeth are conical and mostly uniform in size. The surface cells of the epidermis are modified into horny scales which create a waterproof layer. Reptiles are unable to use their skin for respiration as do amphibians and have a more efficient respiratory system drawing air into their lungs by expanding their chest walls. The heart resembles that of the amphibian but there is a septum which more completely separates the oxygenated and deoxygenated bloodstreams. The reproductive system has evolved for internal fertilization, with a copulatory organ present in most species. The eggs are surrounded by amniotic membranes which prevents them from drying out and are laid on land, or develop internally in some species. The bladder is small as nitrogenous waste is excreted as uric acid.Turtles are notable for their protective shells. They have an inflexible trunk encased in a horny carapace above and a plastron below. These are formed from bony plates embedded in the dermis which are overlain by horny ones and are partially fused with the ribs and spine. The neck is long and flexible and the head and the legs can be drawn back inside the shell. Turtles are vegetarians and the typical reptile teeth have been replaced by sharp, horny plates. In aquatic species, the front legs are modified into flippers.Tuataras superficially resemble lizards but the lineages diverged in the Triassic period. There is one living species, Sphenodon punctatus. The skull has two openings (fenestrae) on either side and the jaw is rigidly attached to the skull. There is one row of teeth in the lower jaw and this fits between the two rows in the upper jaw when the animal chews. The teeth are merely projections of bony material from the jaw and eventually wear down. The brain and heart are more primitive than those of other reptiles, and the lungs have a single chamber and lack bronchi. The tuatara has a well-developed parietal eye on its forehead.Lizards have skulls with only one fenestra on each side, the lower bar of bone below the second fenestra having been lost. This results in the jaws being less rigidly attached which allows the mouth to open wider. Lizards are mostly quadrupeds, with the trunk held off the ground by short, sideways-facing legs, but a few species have no limbs and resemble snakes. Lizards have moveable eyelids, eardrums are present and some species have a central parietal eye.Snakes are closely related to lizards, having branched off from a common ancestral lineage during the Cretaceous period, and they share many of the same features. The skeleton consists of a skull, a hyoid bone, spine and ribs though a few species retain a vestige of the pelvis and rear limbs in the form of pelvic spurs. The bar under the second fenestra has also been lost and the jaws have extreme flexibility allowing the snake to swallow its prey whole. Snakes lack moveable eyelids, the eyes being covered by transparent "spectacle" scales. They do not have eardrums but can detect ground vibrations through the bones of their skull. Their forked tongues are used as organs of taste and smell and some species have sensory pits on their heads enabling them to locate warm-blooded prey.Crocodilians are large, low-slung aquatic reptiles with long snouts and large numbers of teeth. The head and trunk are dorso-ventrally flattened and the tail is laterally compressed. It undulates from side to side to force the animal through the water when swimming. The tough keratinized scales provide body armour and some are fused to the skull. The nostrils, eyes and ears are elevated above the top of the flat head enabling them to remain above the surface of the water when the animal is floating. Valves seal the nostrils and ears when it is submerged. Unlike other reptiles, crocodilians have hearts with four chambers allowing complete separation of oxygenated and deoxygenated blood. === Bird anatomy === Birds are tetrapods but though their hind limbs are used for walking or hopping, their front limbs are wings covered with feathers and adapted for flight. Birds are endothermic, have a high metabolic rate, a light skeletal system and powerful muscles. The long bones are thin, hollow and very light. Air sac extensions from the lungs occupy the centre of some bones. The sternum is wide and usually has a keel and the caudal vertebrae are fused. There are no teeth and the narrow jaws are adapted into a horn-covered beak. The eyes are relatively large, particularly in nocturnal species such as owls. They face forwards in predators and sideways in ducks.The feathers are outgrowths of the epidermis and are found in localized bands from where they fan out over the skin. Large flight feathers are found on the wings and tail, contour feathers cover the bird's surface and fine down occurs on young birds and under the contour feathers of water birds. The only cutaneous gland is the single uropygial gland near the base of the tail. This produces an oily secretion that waterproofs the feathers when the bird preens. There are scales on the legs, feet and claws on the tips of the toes. === Mammal anatomy === Mammals are a diverse class of animals, mostly terrestrial but some are aquatic and others have evolved flapping or gliding flight. They mostly have four limbs but some aquatic mammals have no limbs or limbs modified into fins and the forelimbs of bats are modified into wings. The legs of most mammals are situated below the trunk, which is held well clear of the ground. The bones of mammals are well ossified and their teeth, which are usually differentiated, are coated in a layer of prismatic enamel. The teeth are shed once (milk teeth) during the animal's lifetime or not at all, as is the case in cetaceans. Mammals have three bones in the middle ear and a cochlea in the inner ear. They are clothed in hair and their skin contains glands which secrete sweat. Some of these glands are specialized as mammary glands, producing milk to feed the young. Mammals breathe with lungs and have a muscular diaphragm separating the thorax from the abdomen which helps them draw air into the lungs. The mammalian heart has four chambers and oxygenated and deoxygenated blood are kept entirely separate. Nitrogenous waste is excreted primarily as urea.Mammals are amniotes, and most are viviparous, giving birth to live young. The exception to this are the egg-laying monotremes, the platypus and the echidnas of Australia. Most other mammals have a placenta through which the developing foetus obtains nourishment, but in marsupials, the foetal stage is very short and the immature young is born and finds its way to its mother's pouch where it latches on to a nipple and completes its development. ==== Human anatomy ==== Humans have the overall body plan of a mammal. Humans have a head, neck, trunk (which includes the thorax and abdomen), two arms and hands, and two legs and feet. Generally, students of certain biological sciences, paramedics, prosthetists and orthotists, physiotherapists, occupational therapists, nurses, podiatrists, and medical students learn gross anatomy and microscopic anatomy from anatomical models, skeletons, textbooks, diagrams, photographs, lectures and tutorials, and in addition, medical students generally also learn gross anatomy through practical experience of dissection and inspection of cadavers. The study of microscopic anatomy (or histology) can be aided by practical experience examining histological preparations (or slides) under a microscope. Human anatomy, physiology and biochemistry are complementary basic medical sciences, which are generally taught to medical students in their first year at medical school. Human anatomy can be taught regionally or systemically; that is, respectively, studying anatomy by bodily regions such as the head and chest, or studying by specific systems, such as the nervous or respiratory systems. The major anatomy textbook, Gray's Anatomy, has been reorganized from a systems format to a regional format, in line with modern teaching methods. A thorough working knowledge of anatomy is required by physicians, especially surgeons and doctors working in some diagnostic specialties, such as histopathology and radiology. Academic anatomists are usually employed by universities, medical schools or teaching hospitals. They are often involved in teaching anatomy, and research into certain systems, organs, tissues or cells. == Invertebrate anatomy == Invertebrates constitute a vast array of living organisms ranging from the simplest unicellular eukaryotes such as Paramecium to such complex multicellular animals as the octopus, lobster and dragonfly. They constitute about 95% of the animal species. By definition, none of these creatures has a backbone. The cells of single-cell protozoans have the same basic structure as those of multicellular animals but some parts are specialized into the equivalent of tissues and organs. Locomotion is often provided by cilia or flagella or may proceed via the advance of pseudopodia, food may be gathered by phagocytosis, energy needs may be supplied by photosynthesis and the cell may be supported by an endoskeleton or an exoskeleton. Some protozoans can form multicellular colonies.Metazoans are multicellular organism, different groups of cells of which have separate functions. The most basic types of metazoan tissues are epithelium and connective tissue, both of which are present in nearly all invertebrates. The outer surface of the epidermis is normally formed of epithelial cells and secretes an extracellular matrix which provides support to the organism. An endoskeleton derived from the mesoderm is present in echinoderms, sponges and some cephalopods. Exoskeletons are derived from the epidermis and is composed of chitin in arthropods (insects, spiders, ticks, shrimps, crabs, lobsters). Calcium carbonate constitutes the shells of molluscs, brachiopods and some tube-building polychaete worms and silica forms the exoskeleton of the microscopic diatoms and radiolaria. Other invertebrates may have no rigid structures but the epidermis may secrete a variety of surface coatings such as the pinacoderm of sponges, the gelatinous cuticle of cnidarians (polyps, sea anemones, jellyfish) and the collagenous cuticle of annelids. The outer epithelial layer may include cells of several types including sensory cells, gland cells and stinging cells. There may also be protrusions such as microvilli, cilia, bristles, spines and tubercles.Marcello Malpighi, the father of microscopical anatomy, discovered that plants had tubules similar to those he saw in insects like the silk worm. He observed that when a ring-like portion of bark was removed on a trunk a swelling occurred in the tissues above the ring, and he unmistakably interpreted this as growth stimulated by food coming down from the leaves, and being captured above the ring. === Arthropod anatomy === Arthropods comprise the largest phylum in the animal kingdom with over a million known invertebrate species.Insects possess segmented bodies supported by a hard-jointed outer covering, the exoskeleton, made mostly of chitin. The segments of the body are organized into three distinct parts, a head, a thorax and an abdomen. The head typically bears a pair of sensory antennae, a pair of compound eyes, one to three simple eyes (ocelli) and three sets of modified appendages that form the mouthparts. The thorax has three pairs of segmented legs, one pair each for the three segments that compose the thorax and one or two pairs of wings. The abdomen is composed of eleven segments, some of which may be fused and houses the digestive, respiratory, excretory and reproductive systems. There is considerable variation between species and many adaptations to the body parts, especially wings, legs, antennae and mouthparts.Spiders a class of arachnids have four pairs of legs; a body of two segments—a cephalothorax and an abdomen. Spiders have no wings and no antennae. They have mouthparts called chelicerae which are often connected to venom glands as most spiders are venomous. They have a second pair of appendages called pedipalps attached to the cephalothorax. These have similar segmentation to the legs and function as taste and smell organs. At the end of each male pedipalp is a spoon-shaped cymbium that acts to support the copulatory organ. == Other branches of anatomy == Superficial or surface anatomy is important as the study of anatomical landmarks that can be readily seen from the exterior contours of the body. It enables physicians or veterinary surgeons to gauge the position and anatomy of the associated deeper structures. Superficial is a directional term that indicates that structures are located relatively close to the surface of the body. Comparative anatomy relates to the comparison of anatomical structures (both gross and microscopic) in different animals. Artistic anatomy relates to anatomic studies for artistic reasons. == History == === Ancient === In 1600 BCE, the Edwin Smith Papyrus, an Ancient Egyptian medical text, described the heart, its vessels, liver, spleen, kidneys, hypothalamus, uterus and bladder, and showed the blood vessels diverging from the heart. The Ebers Papyrus (c. 1550 BCE) features a "treatise on the heart", with vessels carrying all the body's fluids to or from every member of the body.Ancient Greek anatomy and physiology underwent great changes and advances throughout the early medieval world. Over time, this medical practice expanded by a continually developing understanding of the functions of organs and structures in the body. Phenomenal anatomical observations of the human body were made, which have contributed towards the understanding of the brain, eye, liver, reproductive organs and the nervous system. The Hellenistic Egyptian city of Alexandria was the stepping-stone for Greek anatomy and physiology. Alexandria not only housed the biggest library for medical records and books of the liberal arts in the world during the time of the Greeks, but was also home to many medical practitioners and philosophers. Great patronage of the arts and sciences from the Ptolemy rulers helped raise Alexandria up, further rivalling the cultural and scientific achievements of other Greek states. Some of the most striking advances in early anatomy and physiology took place in Hellenistic Alexandria. Two of the most famous anatomists and physiologists of the third century were Herophilus and Erasistratus. These two physicians helped pioneer human dissection for medical research. They also conducted vivisections on the cadavers of condemned criminals, which was considered taboo until the Renaissance – Herophilus was recognized as the first person to perform systematic dissections. Herophilus became known for his anatomical works making impressing contributions to many branches of anatomy and many other aspects of medicine. Some of the works included classifying the system of the pulse, the discovery that human arteries had thicker walls then veins, and that the atria were parts of the heart. Herophilus’s knowledge of the human body has provided vital input towards understanding the brain, eye, liver, reproductive organs and nervous system, and characterizing the course of disease. Erasistratus accurately described the structure of the brain, including the cavities and membranes, and made a distinction between its cerebrum and cerebellum During his study in Alexandria, Erasistratus was particularly concerned with studies of the circulatory and nervous systems. He was able to distinguish the sensory and the motor nerves in the human body and believed that air entered the lungs and heart, which was then carried throughout the body. His distinction between the arteries and veins – the arteries carrying the air through the body, while the veins carried the blood from the heart was a great anatomical discovery. Erasistratus was also responsible for naming and describing the function of the epiglottis and the valves of the heart, including the tricuspid. During the third century, Greek physicians were able to differentiate nerves from blood vessels and tendons and to realize that the nerves convey neural impulses. It was Herophilus who made the point that damage to motor nerves induced paralysis. Herophilus named the meninges and ventricles in the brain, appreciated the division between cerebellum and cerebrum and recognized that the brain was the "seat of intellect" and not a "cooling chamber" as propounded by Aristotle Herophilus is also credited with describing the optic, oculomotor, motor division of the trigeminal, facial, vestibulocochlear and hypoglossal nerves. Great feats were made during the third century in both the digestive and reproductive systems. Herophilus was able to discover and describe not only the salivary glands, but the small intestine and liver. He showed that the uterus is a hollow organ and described the ovaries and uterine tubes. He recognized that spermatozoa were produced by the testes and was the first to identify the prostate gland.The anatomy of the muscles and skeleton is described in the Hippocratic Corpus, an Ancient Greek medical work written by unknown authors. Aristotle described vertebrate anatomy based on animal dissection. Praxagoras identified the difference between arteries and veins. Also in the 4th century BCE, Herophilos and Erasistratus produced more accurate anatomical descriptions based on vivisection of criminals in Alexandria during the Ptolemaic dynasty.In the 2nd century, Galen of Pergamum, an anatomist, clinician, writer and philosopher, wrote the final and highly influential anatomy treatise of ancient times. He compiled existing knowledge and studied anatomy through dissection of animals. He was one of the first experimental physiologists through his vivisection experiments on animals. Galen's drawings, based mostly on dog anatomy, became effectively the only anatomical textbook for the next thousand years. His work was known to Renaissance doctors only through Islamic Golden Age medicine until it was translated from the Greek some time in the 15th century. === Medieval to early modern === Anatomy developed little from classical times until the sixteenth century; as the historian Marie Boas writes, "Progress in anatomy before the sixteenth century is as mysteriously slow as its development after 1500 is startlingly rapid". Between 1275 and 1326, the anatomists Mondino de Luzzi, Alessandro Achillini and Antonio Benivieni at Bologna carried out the first systematic human dissections since ancient times. Mondino's Anatomy of 1316 was the first textbook in the medieval rediscovery of human anatomy. It describes the body in the order followed in Mondino's dissections, starting with the abdomen, then the thorax, then the head and limbs. It was the standard anatomy textbook for the next century.Leonardo da Vinci (1452–1519) was trained in anatomy by Andrea del Verrocchio. He made use of his anatomical knowledge in his artwork, making many sketches of skeletal structures, muscles and organs of humans and other vertebrates that he dissected.Andreas Vesalius (1514–1564) (Latinized from Andries van Wezel), professor of anatomy at the University of Padua, is considered the founder of modern human anatomy. Originally from Brabant, Vesalius published the influential book De humani corporis fabrica ("the structure of the human body"), a large format book in seven volumes, in 1543. The accurate and intricately detailed illustrations, often in allegorical poses against Italianate landscapes, are thought to have been made by the artist Jan van Calcar, a pupil of Titian.In England, anatomy was the subject of the first public lectures given in any science; these were given by the Company of Barbers and Surgeons in the 16th century, joined in 1583 by the Lumleian lectures in surgery at the Royal College of Physicians. === Late modern === In the United States, medical schools began to be set up towards the end of the 18th century. Classes in anatomy needed a continual stream of cadavers for dissection and these were difficult to obtain. Philadelphia, Baltimore and New York were all renowned for body snatching activity as criminals raided graveyards at night, removing newly buried corpses from their coffins. A similar problem existed in Britain where demand for bodies became so great that grave-raiding and even anatomy murder were practised to obtain cadavers. Some graveyards were in consequence protected with watchtowers. The practice was halted in Britain by the Anatomy Act of 1832, while in the United States, similar legislation was enacted after the physician William S. Forbes of Jefferson Medical College was found guilty in 1882 of "complicity with resurrectionists in the despoliation of graves in Lebanon Cemetery".The teaching of anatomy in Britain was transformed by Sir John Struthers, Regius Professor of Anatomy at the University of Aberdeen from 1863 to 1889. He was responsible for setting up the system of three years of "pre-clinical" academic teaching in the sciences underlying medicine, including especially anatomy. This system lasted until the reform of medical training in 1993 and 2003. As well as teaching, he collected many vertebrate skeletons for his museum of comparative anatomy, published over 70 research papers, and became famous for his public dissection of the Tay Whale. From 1822 the Royal College of Surgeons regulated the teaching of anatomy in medical schools. Medical museums provided examples in comparative anatomy, and were often used in teaching. Ignaz Semmelweis investigated puerperal fever and he discovered how it was caused. He noticed that the frequently fatal fever occurred more often in mothers examined by medical students than by midwives. The students went from the dissecting room to the hospital ward and examined women in childbirth. Semmelweis showed that when the trainees washed their hands in chlorinated lime before each clinical examination, the incidence of puerperal fever among the mothers could be reduced dramatically. Before the modern medical era, the main means for studying the internal structures of the body were dissection of the dead and inspection, palpation and auscultation of the living. It was the advent of microscopy that opened up an understanding of the building blocks that constituted living tissues. Technical advances in the development of achromatic lenses increased the resolving power of the microscope and around 1839, Matthias Jakob Schleiden and Theodor Schwann identified that cells were the fundamental unit of organization of all living things. Study of small structures involved passing light through them and the microtome was invented to provide sufficiently thin slices of tissue to examine. Staining techniques using artificial dyes were established to help distinguish between different types of tissue. Advances in the fields of histology and cytology began in the late 19th century along with advances in surgical techniques allowing for the painless and safe removal of biopsy specimens. The invention of the electron microscope brought a great advance in resolution power and allowed research into the ultrastructure of cells and the organelles and other structures within them. About the same time, in the 1950s, the use of X-ray diffraction for studying the crystal structures of proteins, nucleic acids and other biological molecules gave rise to a new field of molecular anatomy. Equally important advances have occurred in non-invasive techniques for examining the interior structures of the body. X-rays can be passed through the body and used in medical radiography and fluoroscopy to differentiate interior structures that have varying degrees of opaqueness. Magnetic resonance imaging, computed tomography, and ultrasound imaging have all enabled examination of internal structures in unprecedented detail to a degree far beyond the imagination of earlier generations. == See also == Outline of human anatomy == Notes == == Bibliography == "Anatomy of the Human Body". 20th edition. 1918.

### Instruction: retrieve labels for this: Affirming the consequent, sometimes called converse error, fallacy of the converse or confusion of necessity and sufficiency, is a formal fallacy of inferring the converse from the original statement. For example, "My driveway is wet, so it must be raining" is an example of this fallacy (someone may have turned on a hose). The fallacious statement is based on the true statement that "if it is raining, then the driveway is wet", but is a fallacy because the order of cause and effect have been reversed. The corresponding argument has the general form: P → Q , Q ∴ P {\displaystyle {\frac {P\to Q,Q}{\therefore P}}} An argument of this form is invalid, i.e., the conclusion can be false even when statements 1 and 2 are true. Since P was never asserted as the only sufficient condition for Q, other factors could account for Q (while P was false).To put it differently, if P implies Q, the only inference that can be made is non-Q implies non-P. (Non-P and non-Q designate the opposite propositions to P and Q.) This is known as logical contraposition. Symbolically: ( P → Q ) ↔ ( ¬ Q → ¬ P ) {\displaystyle (P\to Q)\leftrightarrow (\neg Q\to \neg P)} The name affirming the consequent derives from the premise Q, which affirms the "then" clause of the conditional premise. == Examples == Example 1 One way to demonstrate the invalidity of this argument form is with a counterexample with true premises but an obviously false conclusion. For example: If Bill Gates owns Fort Knox, then Bill Gates is rich. Bill Gates is rich. Therefore, Bill Gates owns Fort Knox.Owning Fort Knox is not the only way to be rich. Any number of other ways to be rich exist. However, one can affirm with certainty that "if someone is not rich" (non-Q), then "this person does not own Fort Knox" (non-P). This is the contrapositive of the first statement, and it must be true if and only if the original statement is true. Example 2 Arguments of the same form can sometimes seem superficially convincing, as in the following example: If I had been thrown off the top of the Eiffel Tower, then I would be dead. I am dead. Therefore, I was thrown off the top of the Eiffel Tower.Being thrown off the top of the Eiffel Tower is not the only cause of death, since there exist numerous different causes of death. Affirming the consequent is commonly used in rationalization, and thus appears as a coping mechanism in some people. Example 3 In Catch-22, the chaplain is interrogated for supposedly being 'Washington Irving'/'Irving Washington', who has been blocking out large portions of soldiers' letters home. The colonel has found such a letter, but with the Chaplain's name signed. 'You can read, though, can't you?' the colonel persevered sarcastically. 'The author signed his name.' 'That's my name there.' 'Then you wrote it. Q.E.D.'P in this case is 'The chaplain signs his own name', and Q 'The chaplain's name is written'. The chaplain's name may be written, but he did not necessarily write it, as the colonel falsely concludes (and in fact he did not, as in the novel, Yossarian signed the name). == See also == Appeal to consequences Confusion of the inverse Denying the antecedent ELIZA effect Fallacy of the single cause Fallacy of the undistributed middle Inference to the best explanation Modus ponens Modus tollens Post hoc ergo propter hoc Necessity and sufficiency == References == ### Answer: <Propositional fallacies>

### Instruction: retrieve labels for this: Ambiguity is a type of meaning in which several interpretations are plausible. A common aspect of ambiguity is uncertainty. It is thus an attribute of any idea or statement whose intended meaning cannot be definitively resolved according to a rule or process with a finite number of steps. (The ambi- part of the term reflects an idea of "two", as in "two meanings".) The concept of ambiguity is generally contrasted with vagueness. In ambiguity, specific and distinct interpretations are permitted (although some may not be immediately obvious), whereas with information that is vague, it is difficult to form any interpretation at the desired level of specificity. Context may play a role in resolving ambiguity. For example, the same piece of information may be ambiguous in one context and unambiguous in another. == Linguistic forms == The lexical ambiguity of a word or phrase pertains to its having more than one meaning in the language to which the word belongs. "Meaning" here refers to whatever should be captured by a good dictionary. For instance, the word "bank" has several distinct lexical definitions, including "financial institution" and "edge of a river". Or consider "apothecary". One could say "I bought herbs from the apothecary". This could mean one actually spoke to the apothecary (pharmacist) or went to the apothecary (pharmacy). The context in which an ambiguous word is used often makes it evident which of the meanings is intended. If, for instance, someone says "I buried $100 in the bank", most people would not think someone used a shovel to dig in the mud. However, some linguistic contexts do not provide sufficient information to disambiguate a used word. Lexical ambiguity can be addressed by algorithmic methods that automatically associate the appropriate meaning with a word in context, a task referred to as word sense disambiguation. The use of multi-defined words requires the author or speaker to clarify their context, and sometimes elaborate on their specific intended meaning (in which case, a less ambiguous term should have been used). The goal of clear concise communication is that the receiver(s) have no misunderstanding about what was meant to be conveyed. An exception to this could include a politician whose "weasel words" and obfuscation are necessary to gain support from multiple constituents with mutually exclusive conflicting desires from their candidate of choice. Ambiguity is a powerful tool of political science. More problematic are words whose senses express closely related concepts. "Good", for example, can mean "useful" or "functional" (That's a good hammer), "exemplary" (She's a good student), "pleasing" (This is good soup), "moral" (a good person versus the lesson to be learned from a story), "righteous", etc. " I have a good daughter" is not clear about which sense is intended. The various ways to apply prefixes and suffixes can also create ambiguity ("unlockable" can mean "capable of being unlocked" or "impossible to lock"). Syntactic ambiguity arises when a sentence can have two (or more) different meanings because of the structure of the sentence—its syntax. This is often due to a modifying expression, such as a prepositional phrase, the application of which is unclear. "He ate the cookies on the couch", for example, could mean that he ate those cookies that were on the couch (as opposed to those that were on the table), or it could mean that he was sitting on the couch when he ate the cookies. "To get in, you will need an entrance fee of $10 or your voucher and your drivers' license." This could mean that you need EITHER ten dollars OR BOTH your voucher and your license. Or it could mean that you need your license AND you need EITHER ten dollars OR a voucher. Only rewriting the sentence, or placing appropriate punctuation can resolve a syntactic ambiguity. For the notion of, and theoretic results about, syntactic ambiguity in artificial, formal languages (such as computer programming languages), see Ambiguous grammar. Spoken language can contain many more types of ambiguities which are called phonological ambiguities, where there is more than one way to compose a set of sounds into words. For example, "ice cream" and "I scream". Such ambiguity is generally resolved according to the context. A mishearing of such, based on incorrectly resolved ambiguity, is called a mondegreen. Semantic ambiguity happens when a sentence contains an ambiguous word or phrase—a word or phrase that has more than one meaning. In "We saw her duck" (example due to Richard Nordquist), the word "duck" can refer either to the person's bird (the noun "duck", modified by the possessive pronoun "her"), or to a motion she made (the verb "duck", the subject of which is the objective pronoun "her", object of the verb "saw").Lexical ambiguity is contrasted with semantic ambiguity. The former represents a choice between a finite number of known and meaningful context-dependent interpretations. The latter represents a choice between any number of possible interpretations, none of which may have a standard agreed-upon meaning. This form of ambiguity is closely related to vagueness. Linguistic ambiguity can be a problem in law, because the interpretation of written documents and oral agreements is often of paramount importance. Philosophers (and other users of logic) spend a lot of time and effort searching for and removing (or intentionally adding) ambiguity in arguments because it can lead to incorrect conclusions and can be used to deliberately conceal bad arguments. For example, a politician might say, "I oppose taxes which hinder economic growth", an example of a glittering generality. Some will think he opposes taxes in general because they hinder economic growth. Others may think he opposes only those taxes that he believes will hinder economic growth. In writing, the sentence can be rewritten to reduce possible misinterpretation, either by adding a comma after "taxes" (to convey the first sense) or by changing "which" to "that" (to convey the second sense) or by rewriting it in other ways. The devious politician hopes that each constituent will interpret the statement in the most desirable way, and think the politician supports everyone's opinion. However, the opposite can also be true – an opponent can turn a positive statement into a bad one if the speaker uses ambiguity (intentionally or not). The logical fallacies of amphiboly and equivocation rely heavily on the use of ambiguous words and phrases. In continental philosophy (particularly phenomenology and existentialism), there is much greater tolerance of ambiguity, as it is generally seen as an integral part of the human condition. Martin Heidegger argued that the relation between the subject and object is ambiguous, as is the relation of mind and body, and part and whole.[3] In Heidegger's phenomenology, Dasein is always in a meaningful world, but there is always an underlying background for every instance of signification. Thus, although some things may be certain, they have little to do with Dasein's sense of care and existential anxiety, e.g., in the face of death. In calling his work Being and Nothingness an "essay in phenomenological ontology" Jean-Paul Sartre follows Heidegger in defining the human essence as ambiguous, or relating fundamentally to such ambiguity. Simone de Beauvoir tries to base an ethics on Heidegger's and Sartre's writings (The Ethics of Ambiguity), where she highlights the need to grapple with ambiguity: "as long as philosophers and they [men] have thought, most of them have tried to mask it...And the ethics which they have proposed to their disciples have always pursued the same goal. It has been a matter of eliminating the ambiguity by making oneself pure inwardness or pure externality, by escaping from the sensible world or being engulfed by it, by yielding to eternity or enclosing oneself in the pure moment." Ethics cannot be based on the authoritative certainty given by mathematics and logic, or prescribed directly from the empirical findings of science. She states: "Since we do not succeed in fleeing it, let us, therefore, try to look the truth in the face. Let us try to assume our fundamental ambiguity. It is in the knowledge of the genuine conditions of our life that we must draw our strength to live and our reason for acting". Other continental philosophers suggest that concepts such as life, nature, and sex are ambiguous. Corey Anton has argued that we cannot be certain what is separate from or unified with something else: language, he asserts, divides what is not, in fact, separate. Following Ernest Becker, he argues that the desire to 'authoritatively disambiguate' the world and existence has led to numerous ideologies and historical events such as genocide. On this basis, he argues that ethics must focus on 'dialectically integrating opposites' and balancing tension, rather than seeking a priori validation or certainty. Like the existentialists and phenomenologists, he sees the ambiguity of life as the basis of creativity. In literature and rhetoric, ambiguity can be a useful tool. Groucho Marx's classic joke depends on a grammatical ambiguity for its humor, for example: "Last night I shot an elephant in my pajamas. How he got in my pajamas, I'll never know". Songs and poetry often rely on ambiguous words for artistic effect, as in the song title "Don't It Make My Brown Eyes Blue" (where "blue" can refer to the color, or to sadness). In the narrative, ambiguity can be introduced in several ways: motive, plot, character. F. Scott Fitzgerald uses the latter type of ambiguity with notable effect in his novel The Great Gatsby. Christianity and Judaism employ the concept of paradox synonymously with 'ambiguity'. Many Christians and Jews endorse Rudolf Otto's description of the sacred as 'mysterium tremendum et fascinans', the awe-inspiring mystery which fascinates humans.[dubious – discuss] The orthodox Catholic writer G. K. Chesterton regularly employed paradox to tease out the meanings in common concepts which he found ambiguous or to reveal meaning often overlooked or forgotten in common phrases. (The title of one of his most famous books, Orthodoxy, itself employing such a paradox.) Metonymy involves the use of the name of a subcomponent part as an abbreviation, or jargon, for the name of the whole object (for example "wheels" to refer to a car, or "flowers" to refer to beautiful offspring, an entire plant, or a collection of blooming plants). In modern vocabulary, critical semiotics,[9] metonymy encompasses any potentially ambiguous word substitution that is based on contextual contiguity (located close together), or a function or process that an object performs, such as "sweet ride" to refer to a nice car. Metonym miscommunication is considered a primary mechanism of linguistic humor. == Music == In music, pieces or sections which confound expectations and may be or are interpreted simultaneously in different ways are ambiguous, such as some polytonality, polymeter, other ambiguous meters or rhythms, and ambiguous phrasing, or (Stein 2005, p. 79) any aspect of music. The music of Africa is often purposely ambiguous. To quote Sir Donald Francis Tovey (1935, p. 195), "Theorists are apt to vex themselves with vain efforts to remove uncertainty just where it has a high aesthetic value." == Visual art == In visual art, certain images are visually ambiguous, such as the Necker cube, which can be interpreted in two ways. Perceptions of such objects remain stable for a time, then may flip, a phenomenon called multistable perception. The opposite of such ambiguous images are impossible objects. Pictures or photographs may also be ambiguous at the semantic level: the visual image is unambiguous, but the meaning and narrative may be ambiguous: is a certain facial expression one of excitement or fear, for instance? == Constructed language == Some languages have been created with the intention of avoiding ambiguity, especially lexical ambiguity. Lojban and Loglan are two related languages which have been created for this, focusing chiefly on syntactic ambiguity as well. The languages can be both spoken and written. These languages are intended to provide a greater technical precision over big natural languages, although historically, such attempts at language improvement have been criticized. Languages composed from many diverse sources contain much ambiguity and inconsistency. The many exceptions to syntax and semantic rules are time-consuming and difficult to learn. == Computer science == In computer science, the SI prefixes kilo-, mega- and giga- were historically used in certain contexts to mean either the first three powers of 1024 (1024, 10242 and 10243) contrary to the metric system in which these units unambiguously mean one thousand, one million, and one billion. This usage is particularly prevalent with electronic memory devices (e.g. DRAM) addressed directly by a binary machine register where a decimal interpretation makes no practical sense. Subsequently, the Ki, Mi, and Gi prefixes were introduced so that binary prefixes could be written explicitly, also rendering k, M, and G unambiguous in texts conforming to the new standard — this led to a new ambiguity in engineering documents lacking outward trace of the binary prefixes (necessarily indicating the new style) as to whether the usage of k, M, and G remains ambiguous (old style) or not (new style). Note also that 1 M (where M is ambiguously 1,000,000 or 1,048,576) is less uncertain than the engineering value 1.0e6 (defined to designate the interval 950,000 to 1,050,000), and that as non-volatile storage devices began to commonly exceed 1 GB in capacity (where the ambiguity begins to routinely impact the second significant digit), GB and TB almost always mean 109 and 1012 bytes. == Mathematical notation == Mathematical notation, widely used in physics and other sciences, avoids many ambiguities compared to expression in natural language. However, for various reasons, several lexical, syntactic and semantic ambiguities remain. === Names of functions === The ambiguity in the style of writing a function should not be confused with a multivalued function, which can (and should) be defined in a deterministic and unambiguous way. Several special functions still do not have established notations. Usually, the conversion to another notation requires to scale the argument or the resulting value; sometimes, the same name of the function is used, causing confusions. Examples of such underestablished functions: Sinc function Elliptic integral of the third kind; translating elliptic integral form MAPLE to Mathematica, one should replace the second argument to its square, see Talk:Elliptic integral#List of notations; dealing with complex values, this may cause problems. Exponential integral Hermite polynomial === Expressions === Ambiguous expressions often appear in physical and mathematical texts. It is common practice to omit multiplication signs in mathematical expressions. Also, it is common to give the same name to a variable and a function, for example, f = f ( x ) {\displaystyle f=f(x)} . Then, if one sees f = f ( y + 1 ) {\displaystyle f=f(y+1)} , there is no way to distinguish whether it means f = f ( x ) {\displaystyle f=f(x)} multiplied by ( y + 1 ) {\displaystyle (y+1)} , or function f {\displaystyle f} evaluated at argument equal to ( y + 1 ) {\displaystyle (y+1)} . In each case of use of such notations, the reader is supposed to be able to perform the deduction and reveal the true meaning. Creators of algorithmic languages try to avoid ambiguities. Many algorithmic languages (C++ and Fortran) require the character * as symbol of multiplication. The Wolfram Language used in Mathematica allows the user to omit the multiplication symbol, but requires square brackets to indicate the argument of a function; square brackets are not allowed for grouping of expressions. Fortran, in addition, does not allow use of the same name (identifier) for different objects, for example, function and variable; in particular, the expression f=f(x) is qualified as an error. The order of operations may depend on the context. In most programming languages, the operations of division and multiplication have equal priority and are executed from left to right. Until the last century, many editorials assumed that multiplication is performed first, for example, a / b c {\displaystyle a/bc} is interpreted as a / ( b c ) {\displaystyle a/(bc)} ; in this case, the insertion of parentheses is required when translating the formulas to an algorithmic language. In addition, it is common to write an argument of a function without parenthesis, which also may lead to ambiguity. Sometimes, one uses italics letters to denote elementary functions. In the scientific journal style, the expression s i n α {\displaystyle sin\alpha } means product of variables s {\displaystyle s} , i {\displaystyle i} , n {\displaystyle n} and α {\displaystyle \alpha } , although in a slideshow, it may mean sin ⁡ [ α ] {\displaystyle \sin[\alpha ]} . A comma in subscripts and superscripts sometimes is omitted; it is also ambiguous notation. If it is written T m n k {\displaystyle T_{mnk}} , the reader should guess from the context, does it mean a single-index object, evaluated while the subscript is equal to product of variables m {\displaystyle m} , n {\displaystyle n} and k {\displaystyle k} , or it is indication to a trivalent tensor. The writing of T m n k {\displaystyle T_{mnk}} instead of T m , n , k {\displaystyle T_{m,n,k}} may mean that the writer either is stretched in space (for example, to reduce the publication fees) or aims to increase number of publications without considering readers. The same may apply to any other use of ambiguous notations. Subscripts are also used to denote the argument to a function, as in F x {\displaystyle F_{x}} . === Examples of potentially confusing ambiguous mathematical expressions === sin 2 ⁡ α / 2 {\displaystyle \sin ^{2}\alpha /2} , which could be understood to mean either ( sin ⁡ ( α / 2 ) ) 2 {\displaystyle (\sin(\alpha /2))^{2}} or ( sin ⁡ ( α ) ) 2 / 2 {\displaystyle (\sin(\alpha ))^{2}/2} . In addition, sin 2 ⁡ ( x ) {\displaystyle \sin ^{2}(x)} may mean sin ⁡ ( sin ⁡ ( x ) ) {\displaystyle \sin(\sin(x))} , as exp 2 ⁡ ( x ) {\displaystyle \exp ^{2}(x)} means exp ⁡ ( exp ⁡ ( x ) ) {\displaystyle \exp(\exp(x))} (see tetration). sin − 1 ⁡ α {\displaystyle \sin ^{-1}\alpha } , which by convention means arcsin ⁡ ( α ) {\displaystyle \arcsin(\alpha )} , though it might be thought to mean ( sin ⁡ ( α ) ) − 1 {\displaystyle (\sin(\alpha ))^{-1}} , since sin n ⁡ α {\displaystyle \sin ^{n}\alpha } means ( sin ⁡ ( α ) ) n {\displaystyle (\sin(\alpha ))^{n}} . a / 2 b {\displaystyle a/2b} , which arguably should mean ( a / 2 ) b {\displaystyle (a/2)b} but would commonly be understood to mean a / ( 2 b ) {\displaystyle a/(2b)} . === Notations in quantum optics and quantum mechanics === It is common to define the coherent states in quantum optics with | α ⟩ {\displaystyle ~|\alpha \rangle ~} and states with fixed number of photons with | n ⟩ {\displaystyle ~|n\rangle ~} . Then, there is an "unwritten rule": the state is coherent if there are more Greek characters than Latin characters in the argument, and n {\displaystyle ~n~} photon state if the Latin characters dominate. The ambiguity becomes even worse, if | x ⟩ {\displaystyle ~|x\rangle ~} is used for the states with certain value of the coordinate, and | p ⟩ {\displaystyle ~|p\rangle ~} means the state with certain value of the momentum, which may be used in books on quantum mechanics. Such ambiguities easily lead to confusions, especially if some normalized adimensional, dimensionless variables are used. Expression | 1 ⟩ {\displaystyle |1\rangle } may mean a state with single photon, or the coherent state with mean amplitude equal to 1, or state with momentum equal to unity, and so on. The reader is supposed to guess from the context. === Ambiguous terms in physics and mathematics === Some physical quantities do not yet have established notations; their value (and sometimes even dimension, as in the case of the Einstein coefficients), depends on the system of notations. Many terms are ambiguous. Each use of an ambiguous term should be preceded by the definition, suitable for a specific case. Just like Ludwig Wittgenstein states in Tractatus Logico-Philosophicus: "... Only in the context of a proposition has a name meaning."A highly confusing term is gain. For example, the sentence "the gain of a system should be doubled", without context, means close to nothing. It may mean that the ratio of the output voltage of an electric circuit to the input voltage should be doubled. It may mean that the ratio of the output power of an electric or optical circuit to the input power should be doubled. It may mean that the gain of the laser medium should be doubled, for example, doubling the population of the upper laser level in a quasi-two level system (assuming negligible absorption of the ground-state). The term intensity is ambiguous when applied to light. The term can refer to any of irradiance, luminous intensity, radiant intensity, or radiance, depending on the background of the person using the term. Also, confusions may be related with the use of atomic percent as measure of concentration of a dopant, or resolution of an imaging system, as measure of the size of the smallest detail which still can be resolved at the background of statistical noise. See also Accuracy and precision and its talk. The Berry paradox arises as a result of systematic ambiguity in the meaning of terms such as "definable" or "nameable". Terms of this kind give rise to vicious circle fallacies. Other terms with this type of ambiguity are: satisfiable, true, false, function, property, class, relation, cardinal, and ordinal. == Mathematical interpretation of ambiguity == In mathematics and logic, ambiguity can be considered to be an instance of the logical concept of underdetermination—for example, X = Y {\displaystyle X=Y} leaves open what the value of X is—while its opposite is a self-contradiction, also called inconsistency, paradoxicalness, or oxymoron, or in mathematics an inconsistent system—such as X = 2 , X = 3 {\displaystyle X=2,X=3} , which has no solution. Logical ambiguity and self-contradiction is analogous to visual ambiguity and impossible objects, such as the Necker cube and impossible cube, or many of the drawings of M. C. Escher. == See also == == References == == External links == Zalta, Edward N. (ed.). "Ambiguity". Stanford Encyclopedia of Philosophy.

### Instruction: retrieve labels for this: The aardvark ( ARD-vark; Orycteropus afer) is a medium-sized, burrowing, nocturnal mammal native to Africa. It is the only living species of the order Tubulidentata, although other prehistoric species and genera of Tubulidentata are known. Unlike other insectivores, it has a long pig-like snout, which is used to sniff out food. It roams over most of the southern two-thirds of the African continent, avoiding areas that are mainly rocky. A nocturnal feeder, it subsists on ants and termites, which it will dig out of their hills using its sharp claws and powerful legs. It also digs to create burrows in which to live and rear its young. It receives a "least concern" rating from the IUCN, although its numbers seem to be decreasing. == Naming and taxonomy == === Naming === The aardvark is sometimes colloquially called "African ant bear", "anteater" (not to be confused with the South American anteater), or the "Cape anteater" after the Cape of Good Hope. The name "aardvark" (Afrikaans pronunciation: [ˈɑːrtfark]) comes from earlier Afrikaans (erdvark) and means "earth pig" or "ground pig" (aarde: earth/ground, vark: pig), because of its burrowing habits. The name Orycteropus means burrowing foot, and the name afer refers to Africa. The name of the aardvarks's order, Tubulidentata, comes from the tubule-style teeth. === Taxonomy === The aardvark is not closely related to the pig; rather, it is the sole extant representative of the obscure mammalian order Tubulidentata, in which it is usually considered to form one variable species of the genus Orycteropus, the sole surviving genus in the family Orycteropodidae. The aardvark is not closely related to the South American anteater, despite sharing some characteristics and a superficial resemblance. The similarities are based on convergent evolution. The closest living relatives of the aardvark are the elephant shrews, tenrecs and golden moles. Along with the sirenians, hyraxes, elephants, and their extinct relatives, these animals form the superorder Afrotheria. Studies of the brain have shown the similarities with Condylarthra, and given the clade's status as a wastebasket taxon it may mean some species traditionally classified as "condylarths" are actually stem-aardvarks. === Evolutionary history === Based on fossils, Bryan Patterson has concluded that early relatives of the aardvark appeared in Africa around the end of the Paleocene. The ptolemaiidans, a mysterious clade of mammals with uncertain affinities, may actually be stem-aardvarks, either as a sister clade to Tubulidentata or as a grade leading to true tubulidentates.The first unambiguous tubulidentate was probably Myorycteropus africanus from Kenyan Miocene deposits. The earliest example from the genus Orycteropus was Orycteropus mauritanicus, found in Algeria in deposits from the middle Miocene, with an equally old version found in Kenya. Fossils from the aardvark have been dated to 5 million years, and have been located throughout Europe and the Near East.The mysterious Pleistocene Plesiorycteropus from Madagascar was originally thought to be a tubulidentate that was descended from ancestors that entered the island during the Eocene. However, a number of subtle anatomical differences coupled with recent molecular evidence now lead researchers to believe that Plesiorycteropus is a relative of golden moles and tenrecs that achieved an aardvark-like appearance and ecological niche through convergent evolution. === Subspecies === The aardvark has seventeen poorly defined subspecies listed: Orycteropus afer afer O. a. adametzi Grote, 1921 O. a. aethiopicus Sundevall, 1843 O. a. angolensis Zukowsky & Haltenorth, 1957 O. a. erikssoni Lönnberg, 1906 O. a. faradjius Hatt, 1932 O. a. haussanus Matschie, 1900 O. a. kordofanicus Rothschild, 1927 O. a. lademanni Grote, 1911 O. a. leptodon Hirst, 1906 O. a. matschiei Grote, 1921 O. a. observandus Grote, 1921 O. a. ruvanensis Grote, 1921 O. a. senegalensis Lesson, 1840 O. a. somalicus Lydekker, 1908 O. a. wardi Lydekker, 1908 O. a. wertheri Matschie, 1898The 1911 Encyclopædia Britannica also mentions O. a. capensis or Cape ant-bear from South Africa. == Description == The aardvark is vaguely pig-like in appearance. Its body is stout with a prominently arched back and is sparsely covered with coarse hairs. The limbs are of moderate length, with the rear legs being longer than the forelegs. The front feet have lost the pollex (or 'thumb'), resulting in four toes, while the rear feet have all five toes. Each toe bears a large, robust nail which is somewhat flattened and shovel-like, and appears to be intermediate between a claw and a hoof. Whereas the aardvark is considered digitigrade, it appears at time to be plantigrade. This confusion happens because when it squats it stands on its soles.An aardvark's weight is typically between 60 and 80 kilograms (130–180 lb). An aardvark's length is usually between 105 and 130 centimetres (3.44–4.27 ft), and can reach lengths of 2.2 metres (7 ft 3 in) when its tail (which can be up to 70 centimetres (28 in)) is taken into account. It is 60 centimetres (24 in) tall at the shoulder, and has a girth of about 100 centimetres (3.3 ft). It is the largest member of the proposed clade Afroinsectiphilia. The aardvark is pale yellowish-gray in color and often stained reddish-brown by soil. The aardvark's coat is thin, and the animal's primary protection is its tough skin. Its hair is short on its head and tail; however its legs tend to have longer hair. The hair on the majority of its body is grouped in clusters of 3-4 hairs. The hair surrounding its nostrils is dense to help filter particulate matter out as it digs. Its tail is very thick at the base and gradually tapers. === Head === The greatly elongated head is set on a short, thick neck, and the end of the snout bears a disc, which houses the nostrils. It contains a thin but complete zygomatic arch. The head of the aardvark contains many unique and different features. One of the most distinctive characteristics of the Tubulidentata is their teeth. Instead of having a pulp cavity, each tooth has a cluster of thin, hexagonal, upright, parallel tubes of vasodentin (a modified form of dentine), with individual pulp canals, held together by cementum. The number of columns is dependent on the size of the tooth, with the largest having about 1,500. The teeth have no enamel coating and are worn away and regrow continuously. The aardvark is born with conventional incisors and canines at the front of the jaw, which fall out and are not replaced. Adult aardvarks have only cheek teeth at the back of the jaw, and have a dental formula of: 0.0.2-3.30.0.2.3 These remaining teeth are peg-like and rootless and are of unique composition. The teeth consist of 14 upper and 12 lower jaw molars. The nasal area of the aardvark is another unique area, as it contains ten nasal conchae, more than any other placental mammal.The sides of the nostrils are thick with hair. The tip of the snout is highly mobile and is moved by modified mimetic muscles. The fleshy dividing tissue between its nostrils probably has sensory functions, but it is uncertain whether they are olfactory or vibratory in nature. Its nose is made up of more turbinate bones than any other mammal, with between 9 and 11, compared to dogs with 4 to 5. With a large quantity of turbinate bones, the aardvark has more space for the moist epithelium, which is the location of the olfactory bulb. The nose contains nine olfactory bulbs, more than any other mammal. Its keen sense of smell is not just from the quantity of bulbs in the nose but also in the development of the brain, as its olfactory lobe is very developed. The snout resembles an elongated pig snout. The mouth is small and tubular, typical of species that feed on ants and termites. The aardvark has a long, thin, snakelike, protruding tongue (as much as 30 centimetres (12 in) long) and elaborate structures supporting a keen sense of smell. The ears, which are very effective, are disproportionately long, about 20–25 centimetres (7.9–9.8 in) long. The eyes are small for its head, and consist only of rods. === Digestive system === The aardvark's stomach has a muscular pyloric area that acts as a gizzard to grind swallowed food up, thereby rendering chewing unnecessary. Its cecum is large. Both sexes emit a strong smelling secretion from an anal gland. Its salivary glands are highly developed and almost completely ring the neck; their output is what causes the tongue to maintain its tackiness. The female has two pairs of teats in the inguinal region.Genetically speaking, the aardvark is a living fossil, as its chromosomes are highly conserved, reflecting much of the early eutherian arrangement before the divergence of the major modern taxa. == Habitat and range == Aardvarks are found in sub-Saharan Africa, where suitable habitat (savannas, grasslands, woodlands and bushland) and food (i.e., ants and termites) is available. They spend the daylight hours in dark underground burrows to avoid the heat of the day. The only major habitat that they are not present in is swamp forest, as the high water table precludes digging to a sufficient depth. They also avoid terrain rocky enough to cause problems with digging. They have been documented as high as 3,200 metres (10,500 ft) in Ethiopia. They are present throughout sub-Saharan Africa all the way to South Africa with few exceptions. These exceptions include the coastal areas of Namibia, Ivory Coast, and Ghana. They are not found in Madagascar. == Ecology and behavior == Aardvarks live for up to 23 years in captivity. Its keen hearing warns it of predators: lions, leopards, cheetahs, hunting dogs, hyenas, and pythons. Some humans also hunt aardvarks for meat. Aardvarks can dig fast or run in zigzag fashion to elude enemies, but if all else fails, they will strike with their claws, tail and shoulders, sometimes flipping onto their backs lying motionless except to lash out with all four feet. They are capable of causing substantial damage to unprotected areas of an attacker. They will also dig to escape as they can, when pressed, dig extremely quickly. Their thick skin also protects them to some extent. === Feeding === The aardvark is nocturnal and is a solitary creature that feeds almost exclusively on ants and termites (myrmecophagy); the only fruit eaten by aardvarks is the aardvark cucumber. In fact, the cucumber and the aardvark have a symbiotic relationship as they eat the subterranean fruit, then defecate the seeds near their burrows, which then grow rapidly due to the loose soil and fertile nature of the area. The time spent in the intestine of the aardvark helps the fertility of the seed, and the fruit provides needed moisture for the aardvark. They avoid eating the African driver ant and red ants. Due to their stringent diet requirements, they require a large range to survive. An aardvark emerges from its burrow in the late afternoon or shortly after sunset, and forages over a considerable home range encompassing 10 to 30 kilometres (6.2 to 18.6 mi). While foraging for food, the aardvark will keep its nose to the ground and its ears pointed forward, which indicates that both smell and hearing are involved in the search for food. They zig-zag as they forage and will usually not repeat a route for 5–8 days as they appear to allow time for the termite nests to recover before feeding on it again.During a foraging period, they will stop and dig a "V" shaped trench with their forefeet and then sniff it profusely as a means to explore their location. When a concentration of ants or termites is detected, the aardvark digs into it with its powerful front legs, keeping its long ears upright to listen for predators, and takes up an astonishing number of insects with its long, sticky tongue—as many as 50,000 in one night have been recorded. Its claws enable it to dig through the extremely hard crust of a termite or ant mound quickly. It avoids inhaling the dust by sealing the nostrils. When successful, the aardvark's long (up to 30 centimetres (12 in)) tongue licks up the insects; the termites' biting, or the ants' stinging attacks are rendered futile by the tough skin. After an aardvark visit at a termite mound, other animals will visit to pick up all the leftovers. Termite mounds alone don't provide enough food for the aardvark, so they look for termites that are on the move. When these insects move, they can form columns 10–40 metres (33–131 ft) long and these tend to provide easy pickings with little effort exerted by the aardvark. These columns are more common in areas of livestock or other hoofed animals. The trampled grass and dung attract termites from Odontotermes, Microtermes, and Pseudacanthotermes genera.On a nightly basis they tend to be more active during the first portion of the night time (20:00-00:00); however, they don't seem to prefer bright or dark nights over the other. During adverse weather or if disturbed they will retreat to their burrow systems. They cover between 2 and 5 kilometres (1.2 and 3.1 mi) per night; however, some studies have shown that they may traverse as far as 30 kilometres (19 mi) in a night. === Vocalization === The aardvark is a rather quiet animal. However, it does make soft grunting sounds as it forages and loud grunts as it makes for its tunnel entrance. It makes a bleating sound if frightened. When it is threatened it will make for one of its burrows. If one is not close it will dig a new one rapidly. This new one will be short and require the aardvark to back out when the coast is clear. === Movement === The aardvark is known to be a good swimmer and has been witnessed successfully swimming in strong currents. It can dig a yard of tunnel in about five minutes, but otherwise moves fairly slowly. When leaving the burrow at night, they pause at the entrance for about ten minutes, sniffing and listening. After this period of watchfulness, it will bound out and within seconds it will be 10 metres (33 ft) away. It will then pause, prick its ears, twisting its head to listen, then jump and move off to start foraging.Aside from digging out ants and termites, the aardvark also excavates burrows in which to live; of which they generally fall into three categories: burrows made while foraging, refuge and resting location, and permanent homes. Temporary sites are scattered around the home range and are used as refuges, while the main burrow is also used for breeding. Main burrows can be deep and extensive, have several entrances and can be as long as 13 metres (43 ft). These burrows can be large enough for a man to enter. The aardvark changes the layout of its home burrow regularly, and periodically moves on and makes a new one. The old burrows are an important part of the African wildlife scene. As they are vacated, then they are inhabited by smaller animals like the African wild dog, ant-eating chat, Nycteris thebaica and warthogs. Other animals that use them are hares, mongooses, hyenas, owls, pythons, and lizards. Without these refuges many animals would die during wildfire season. Only mothers and young share burrows; however, the aardvark is known to live in small family groups or as a solitary creature. If attacked in the tunnel, it will escape by digging out of the tunnel thereby placing the fresh fill between it and its predator, or if it decides to fight it will roll onto its back, and attack with its claws. The aardvark has been known to sleep in a recently excavated ant nest, which also serves as protection from its predators. === Reproduction === Aardvarks pair only during the breeding season; after a gestation period of seven months, one cub weighing around 1.7–1.9 kilograms (3.7–4.2 lb) is born during May–July. When born, the young has flaccid ears and many wrinkles. When nursing, it will nurse off each teat in succession. After two weeks, the folds of skin disappear and after three, the ears can be held upright. After 5–6 weeks, body hair starts growing. It is able to leave the burrow to accompany its mother after only two weeks and eats termites at 9 weeks, and is weaned between three months and 16 weeks. At six months of age, it is able to dig its own burrows, but it will often remain with the mother until the next mating season, and is sexually mature from approximately two years of age. == Conservation == Aardvarks were thought to have declining numbers, however, this is possibly due to the fact that they are not readily seen. There are no definitive counts because of their nocturnal and secretive habits; however, their numbers seem to be stable overall. They are not considered common anywhere in Africa, but due to their large range, they maintain sufficient numbers. There may be a slight decrease in numbers in eastern, northern, and western Africa. Southern African numbers are not decreasing. It receives an official designation from the IUCN as least concern. However, they are a species in a precarious situation, as they are so dependent on such specific food; therefore if a problem arises with the abundance of termites, the species as a whole would be affected drastically.Aardvarks handle captivity well. The first zoo to have one was London Zoo in 1869, which had an animal from South Africa. == Mythology and popular culture == In African folklore, the aardvark is much admired because of its diligent quest for food and its fearless response to soldier ants. Hausa magicians make a charm from the heart, skin, forehead, and nails of the aardvark, which they then proceed to pound together with the root of a certain tree. Wrapped in a piece of skin and worn on the chest, the charm is said to give the owner the ability to pass through walls or roofs at night. The charm is said to be used by burglars and those seeking to visit young girls without their parents' permission. Also, some tribes, such as the Margbetu, Ayanda, and Logo, will use aardvark teeth to make bracelets, which are regarded as good luck charms. The meat, which has a resemblance to pork, is eaten in certain cultures.The Egyptian god Set is usually depicted with the head of an unidentified animal, whose similarity to an aardvark has been noted in scholarship.The titular character of Arthur, an animated television series for children based on a book series and produced by WGBH, shown in more than 180 countries, is an aardvark.Otis the Aardvark was a puppet character used on Children's BBC programming. An aardvark features as the antagonist in the cartoon The Ant and the Aardvark as well as in the Canadian animated series The Raccoons. In the military, the Air Force supersonic fighter-bomber F-111/FB-111 was nicknamed the Aardvark because of its long nose resembling the animal. It also had similarities with its nocturnal missions flown at a very low level employing ordnance that could penetrate deep into the ground. In the US Navy, the squadron VF-114 was nicknamed the Aardvarks, flying F-4s and then F-14s. The squadron mascot was adapted from the animal in the comic strip B.C., which the F-4 was said to resemble. Cerebus the Aardvark is a 300-issue comic book series by Dave Sim. == Footnotes == == References == == External links == "Aardvarks at the Bronx Zoo". Retrieved 2013-11-18.

### Instruction: retrieve labels for this: The aardwolf (Proteles cristata) is a small, insectivorous mammal, native to East and Southern Africa. Its name means "earth wolf" in Afrikaans and Dutch. It is also called "maanhaar jackal" (Afrikaans for "mane jackal") or civet hyena, based on its habit of secreting substances from its anal gland, a characteristic shared with the civet. The aardwolf is in the same family as the hyena. Unlike many of its relatives in the order Carnivora, the aardwolf does not hunt large animals. It eats insects and insect larvae, mainly termites; one aardwolf can lap up as many as 250,000 termites during a single night using its long, sticky tongue. The aardwolf lives in the shrublands of eastern and southern Africa – open lands covered with stunted trees and shrubs. It is nocturnal, resting in burrows during the day and emerging at night to seek food. == Taxonomy == The aardwolf is the only surviving species in the mammalian subfamily Protelinae. There is disagreement as to whether the species is monotypic. or can be divided into subspecies P. c. cristatus of Southern Africa and P. c. septentrionalis of East Africa. Recent studies have shown that the aardwolf probably broke away from the rest of the hyena family early on; however, how early is still unclear, as the fossil record and genetic studies disagree by 10 million years.The aardwolf is generally classified with the Hyaenidae, though it was formerly placed into the family Protelidae. Early on, scientists felt that it was merely mimicking the striped hyena, which subsequently led to the creation of Protelidae. == Etymology == The generic name proteles comes from two words both of Greek origin, protos and teleos which combined means "complete in front" based on the fact that they have five toes on their front feet and four on the rear. The specific name, cristatus, comes from Latin and means "provided with a comb", relating to their mane. == Physical characteristics == The aardwolf resembles a very thin striped hyena, but with a more-slender muzzle, black vertical stripes on a coat of yellowish fur, and a long, distinct mane down the midline of the neck and back. It also has one or two diagonal stripes down the fore- and hind-quarters, along with several stripes on its legs. The mane is raised during confrontations to make the aardwolf appear larger. It is missing the throat spot that others in the family have. Its lower leg (from the knee down) is all black, and its tail is bushy with a black tip. The aardwolf is about 55 to 80 cm (22 to 31 in) long, excluding its bushy tail, which is about 20–30 cm (7.9–11.8 in) long, and stands about 40 to 50 cm (16 to 20 in) tall at the shoulders. An adult aardwolf weighs approximately 7–10 kg (15–22 lb), sometimes reaching 15 kg (33 lb). The aardwolves in the south of the continent tend to be smaller (about 10 kg (22 lb))than the eastern version (around 14 kg (31 lb)). The front feet have five toes each, unlike the four-toed hyena. The teeth and skull are similar to those of other hyenas, though smaller, and its cheek teeth are specialised for eating insects. It does still have canines, but, unlike other hyenas, these teeth are used primarily for fighting and defense. Its ears, which are large, are very similar to those of the striped hyena.As an aardwolf ages, it will normally lose some of its teeth, though this has little impact on its feeding habits due to the softness of the insects that it eats. == Distribution and habitat == Aardwolves live in open, dry plains and bushland, avoiding mountainous areas. Due to their specific food requirements, they are only found in regions where termites of the family Hodotermitidae occur. Termites of this family depend on dead and withered grass and are most populous in heavily grazed grasslands and savannahs, including farmland. For most of the year, aardwolves spend time in shared territories consisting of up to a dozen dens, which are occupied for six weeks at a time.There are two distinct populations: one in Southern Africa, and another in East and Northeast Africa. The species does not occur in the intermediary miombo forests. An adult pair, along with their most-recent offspring, occupies a territory of 1–4 km2 (0.39–1.54 sq mi). == Behavior == Aardwolves are shy and nocturnal, sleeping in underground burrows by day. They will, on occasion during the winter, become diurnal feeders. This happens during the coldest periods as they then stay in at night to conserve heat.They have often been mistaken for solitary animals. In fact, they live as monogamous pairs with their young. If their territory is infringed upon, they will chase the intruder up to 400 m (1,300 ft) or to the border. If the intruder is caught, which rarely happens, a fight will occur, which is accompanied by soft clucking, hoarse barking, and a type of roar. The majority of incursions occur during mating season, when they can occur once or twice per week. When food is scarce, the stringent territorial system may be abandoned and as many as three pairs may occupy a "single territory".The territory is marked by both sexes, as they both have developed anal glands from which they extrude a black substance that is smeared on rocks or grass stalks in 5-millimetre (0.20 in)-long streaks. Aardwolves also have scent glands on the forefoot and penile pad. They often mark near termite mounds within their territory every 20 minutes or so. If they are patrolling their territorial boundaries, the marking frequency increases drastically, to once every 50 m (160 ft). At this rate, an individual may mark 60 marks per hour, and upwards of 200 per night.An aardwolf pair may have up to 10 dens, and numerous feces middens, within their territory. When they deposit excreta at their middens, they dig a small hole and cover it with sand. Their dens are usually abandoned aardvark, springhare, or porcupine dens, or on occasion they are crevices in rocks. They will also dig their own dens, or enlarge dens started by springhares. They typically will only use one or two dens at a time, rotating through all of their dens every six months. During the summer, they may rest outside their den during the night, and sleep underground during the heat of the day. Aardwolves are not fast runners nor are they particularly adept at fighting off predators. Therefore, when threatened, the aardwolf may attempt to mislead its foe by doubling back on its tracks. If confronted, it may raise its mane in an attempt to appear more menacing. It also emits a foul-smelling liquid from its anal glands. === Feeding === The aardwolf feeds primarily on termites and more specifically on Trinervitermes. This genus of termites has different species throughout the aardwolf's range. In East Africa, they eat T. bettonianus, and in central Africa, they eat T. rhodesiensis, and finally in southern Africa, they eat T. trinervoides. Their technique consists of licking them off the ground as opposed to the aardvark, which digs into the mound. They locate their food by sound and also from the scent secreted by the soldier termites. An aardwolf may consume up to 250,000 termites per night using its sticky, long tongue. They do not destroy the termite mound or consume the entire colony, thus ensuring that the termites can rebuild and provide a continuous supply of food. They often memorize the location of such nests and return to them every few months. During certain seasonal events, such as the onset of the rainy season and the cold of midwinter, the primary termites become scarce, so the need for other foods becomes pronounced. During these times, the southern aardwolf will seek out Hodotermes mossambicus, a type of harvester termite active in the afternoon, which explains some of their diurnal behavior in the winter. The eastern aardwolf, during the rainy season, subsists on termites from the genera Odontotermes and Macrotermes. They are also known to feed on other insects, larvae, eggs, and, some sources say, occasionally small mammals and birds, but these constitute a very small percentage of their total diet. Unlike other hyenas, aardwolves do not scavenge or kill larger animals. Contrary to popular myths, aardwolves do not eat carrion, and if they are seen eating while hunched over a dead carcass, they are actually eating larvae and beetles. Also, contrary to some sources, they do not like meat, unless it is finely ground or cooked for them. The adult aardwolf was formerly assumed to forage in small groups, but more recent research has shown that they are primarily solitary foragers, necessary because of the scarcity of their insect prey. Their primary source, Trinervitermes, forages in small but dense patches of 25–100 cm (9.8–39.4 in). While foraging, the aardwolf can cover about 1 km (0.62 mi) per hour, which translates to 8–12 km (5.0–7.5 mi) per summer night and 3–8 km (1.9–5.0 mi) per winter night. === Breeding === The breeding season varies depending on location, but normally takes place during autumn or spring. In South Africa, breeding occurs in early July. During the breeding season, unpaired male aardwolves search their own territory, as well as others, for a female to mate with. Dominant males also mate opportunistically with the females of less dominant neighboring aardwolves, which can result in conflict between rival males. Dominant males even go a step further and as the breeding season approaches, they make increasingly greater and greater incursions onto weaker males' territories. As the female comes into oestrus, they add pasting to their tricks inside of the other territories, sometimes doing so more in rivals' territories than their own. Females will also, when given the opportunity, mate with the dominant male, which increases the chances of the dominant male guarding "his" cubs with her. Copulation lasts between 1 and 4.5 hours. Gestation lasts between 89 and 92 days, producing two to five cubs (most often two or three) during the rainy season (November–December), when termites are more active. They are born with their eyes open, but initially are helpless, and weigh around 200–350 g (7.1–12.3 oz). The first six to eight weeks are spent in the den with their parents. The male may spend up to six hours a night watching over the cubs while the mother is out looking for food. After three months, they begin supervised foraging, and by four months are normally independent, though they often share a den with their mother until the next breeding season. By the time the next set of cubs is born, the older cubs have moved on. Aardwolves generally achieve sexual maturity at one and a half to two years of age. == Conservation == The aardwolf has not seen decreasing numbers and they are relatively widespread throughout eastern Africa. They are not common throughout their range, as they maintain a density of no more than 1 per square kilometer, if the food is good. Because of these factors, the IUCN has rated the aardwolf as least concern. In some areas, they are persecuted by man because of the mistaken belief that they prey on livestock; however, they are actually beneficial to the farmers because they eat termites that are detrimental. In other areas, the farmers have recognized this, but they are still killed, on occasion, for their fur. Dogs and insecticides are also common killers of the aardwolf. == Interaction with humans == Aardwolfs are common sights at zoos. Frankfurt Zoo in Germany was home to the oldest recorded aardwolf in captivity at 18 years and 11 months. == Notes == == Footnotes == == References == Anderson, M.; Mills, G. (2008).

### Instruction: retrieve labels for this: Adobe (US: ( listen), UK: ; Spanish: [aˈðoβe]) is a building material made from earth and other organic materials. Adobe means mudbrick in Spanish, but in some English-speaking regions of Spanish heritage, the term is used to refer to any kind of earth construction. Most adobe buildings are similar in appearance to cob and rammed earth buildings. Adobe is among the earliest building materials, and is used throughout the world. == Description == Adobe bricks are rectangular prisms small enough that they can quickly air dry individually without cracking. They can be subsequently assembled, with the application of adobe mud to bond the individual bricks into a structure. There is no standard size, with substantial variations over the years and in different regions. In some areas a popular size measured 8" inches x 4" inches x 12" inches weighing about 25 pounds; in other contexts the size is 10" x 4" x 14" weighing about 35 pounds. The maximum sizes can reach up to 100 pound; above this weight it becomes difficult to move the pieces, and it is preferably to ram the mud in situ, resulting in a different typology known as rammed earth. == Strength == In dry climates, adobe structures are extremely durable, and account for some of the oldest existing buildings in the world. Adobe buildings offer significant advantages due to their greater thermal mass, but they are known to be particularly susceptible to earthquake damage if they are not somehow reinforced. Cases where adobe structures were widely damaged during earthquakes include the 1976 Guatemala earthquake, the 2003 Bam earthquake, and the 2010 Chile earthquake. == Distribution == Buildings made of sun-dried earth are common throughout the world (Middle East, Western Asia, North Africa, West Africa, South America, southwestern North America, Spain, and Eastern Europe.) Adobe had been in use by indigenous peoples of the Americas in the Southwestern United States, Mesoamerica, and the Andes for several thousand years. Puebloan peoples built their adobe structures with handsful or basketsful of adobe, until the Spanish introduced them to making bricks. Adobe bricks were used in Spain from the Late Bronze and Iron Ages (eighth century BCE onwards). Its wide use can be attributed to its simplicity of design and manufacture, and economics.A distinction is sometimes made between the smaller adobes, which are about the size of ordinary baked bricks, and the larger adobines, some of which may be one to two yards (1–2 m) long. == Etymology == The word adobe has existed for around 4000 years with relatively little change in either pronunciation or meaning. The word can be traced from the Middle Egyptian (c. 2000 BC) word ɟbt "mudbrick." Middle Egyptian evolved into Late Egyptian, Demotic or "pre-Coptic", and finally to Coptic (c. 600 BC), where it appeared as τωωβε tōʾpə. This was adopted into Arabic as الطوب aṭ-ṭawbu or aṭ-ṭūbu, with the definite article al- attached. tuba, This was assimilated into the Old Spanish language as adobe [aˈdobe], probably via Mozarabic. English borrowed the word from Spanish in the early 18th century, still referring to mudbrick construction. In more modern English usage, the term "adobe" has come to include a style of architecture popular in the desert climates of North America, especially in New Mexico., regardless of the construction method. == Composition == An adobe brick is a composite material made of earth mixed with water and an organic material such as straw or dung. The soil composition typically contains sand, silt and clay. Straw is useful in binding the brick together and allowing the brick to dry evenly, thereby preventing cracking due to uneven shrinkage rates through the brick. Dung offers the same advantage. The most desirable soil texture for producing the mud of adobe is 15% clay, 10–30% silt, and 55–75% fine sand. Another source quotes 15–25% clay and the remainder sand and coarser particles up to cobbles 50 to 250 mm (2 to 10 in), with no deleterious effect. Modern adobe is stabilized with either emulsified asphalt or Portland cement up to 10% by weight. No more than half the clay content should be expansive clays, with the remainder non-expansive illite or kaolinite. Too much expansive clay results in uneven drying through the brick, resulting in cracking, while too much kaolinite will make a weak brick. Typically the soils of the Southwest United States, where such construction has been widely used, are an adequate composition. == Material properties == Adobe walls are load bearing, i.e. they carry their own weight into the foundation rather than by another structure, hence the adobe must have sufficient compressive strength. In the United States, most building codes call for a minimum compressive strength of 300 lbf/in2 (2.07 newton/mm2) for the adobe block. Adobe construction should be designed so as to avoid lateral structural loads that would cause bending loads. The building codes require the building sustain a 1 g lateral acceleration earthquake load. Such an acceleration will cause lateral loads on the walls, resulting in shear and bending and inducing tensile stresses. To withstand such loads, the codes typically call for a tensile modulus of rupture strength of at least 50 lbf/in2 (0.345 newton/mm2) for the finished block. In addition to being an inexpensive material with a small resource cost, adobe can serve as a significant heat reservoir due to the thermal properties inherent in the massive walls typical in adobe construction. In climates typified by hot days and cool nights, the high thermal mass of adobe mediates the high and low temperatures of the day, moderating the temperature of the living space. The massive walls require a large and relatively long input of heat from the sun (radiation) and from the surrounding air (convection) before they warm through to the interior. After the sun sets and the temperature drops, the warm wall will continue to transfer heat to the interior for several hours due to the time-lag effect. Thus, a well-planned adobe wall of the appropriate thickness is very effective at controlling inside temperature through the wide daily fluctuations typical of desert climates, a factor which has contributed to its longevity as a building material. Thermodynamic material properties are sparsely quoted. The thermal resistance of adobe is quoted as having an R-value of R0 = 0.41 h ft2 °F/(Btu in) and a conductivity of 0.57 W/(m K) quoted from another source. A third source provides the following properties: conductivity=0.30 Btu/(h ft °F); heat capacity=0.24 Btu/(lb °F); density=106 lb/ft3 (1700 kg/m3). To determine the total R-value of a wall for example, multiply R0 by the thickness of the wall. From knowledge of the adobe density, heat capacity and a diffusivity value, the conductivity is found to be k = 0.20 Btu/(h ft °F) or 0.35 W/(m K). The heat capacity is commonly quoted as cp = 0.20 Btu/(lb F) or 840 joules/(kg K). The density is 95 lb/ft3 or 1520 kg/m3. The thermal diffusivity is calculated to be 0.0105 ft2/h or 2.72x10−7 m2/s. == Uses == === Poured and puddled adobe walls === Poured and puddled adobe (puddled clay, piled earth), today called cob, is made by placing soft adobe in layers, rather than by making individual dried bricks or using a form. "Puddle" is a general term for a clay or clay and sand-based material worked into a dense, plastic state. These are the oldest methods of building with adobe in the Americas until holes in the ground were used as forms, and later wooden forms used to make individual bricks were introduced by the Spanish. === Adobe bricks === Bricks made from adobe are usually made by pressing the mud mixture into an open timber frame. In North America, the brick is typically about 25 by 36 cm (10 by 14 in) in size. The mixture is molded into the frame, which is removed after initial setting. After drying for a few hours, the bricks are turned on edge to finish drying. Slow drying in shade reduces cracking. The same mixture, without straw, is used to make mortar and often plaster on interior and exterior walls. Some ancient cultures used lime-based cement for the plaster to protect against rain damage.Depending on the form into which the mixture is pressed, adobe can encompass nearly any shape or size, provided drying is even and the mixture includes reinforcement for larger bricks. Reinforcement can include manure, straw, cement, rebar or wooden posts. Experience has shown straw, cement, or manure added to a standard adobe mixture can all produce a stronger, more crack-resistant brick. A test is done on the soil content first. To do so, a sample of the soil is mixed into a clear container with some water, creating an almost completely saturated liquid. The container is shaken vigorously for one minute. It is then allowed to settle for a day until the soil has settled into layers. Heavier particles settle out first, sand above, silt above that and very fine clay and organic matter will stay in suspension for days. After the water has cleared, percentages of the various particles can be determined. Fifty to 60 percent sand and 35 to 40 percent clay will yield strong bricks. The Cooperative State Research, Education, and Extension Service at New Mexico State University recommends a mix of not more than 1/3 clay, not less than 1/2 sand, and never more than 1/3 silt. === Adobe wall construction === The ground supporting an adobe structure should be compressed, as the weight of adobe wall is significant and foundation settling may cause cracking of the wall. Footing depth is to below the ground frost level. The footing and stem wall are commonly 24 and 14 inches thick, respectively. Modern construction codes call for the use of reinforcing steel in the footing and stem wall. Adobe bricks are laid by course. Adobe walls usually never rise above two stories as they are load bearing and adobe has low structural strength. When creating window and door openings, a lintel is placed on top of the opening to support the bricks above. Atop the last courses of brick, bond beams made of heavy wood beams or modern reinforced concrete are laid to provide a horizontal bearing plate for the roof beams and to redistribute lateral earthquake loads to shear walls more able to carry the forces. To protect the interior and exterior adobe walls, finishes such as mud plaster, whitewash or stucco can be applied. These protect the adobe wall from water damage, but need to be reapplied periodically. Alternatively, the walls can be finished with other nontraditional plasters that provide longer protection. Bricks made with stabilized adobe generally do not need protection of plasters. === Adobe roof === The traditional adobe roof has been constructed using a mixture of soil/clay, water, sand and organic materials. The mixture was then formed and pressed into wood forms, producing rows of dried earth bricks that would then be laid across a support structure of wood and plastered into place with more adobe. Depending on the materials available, a roof may be assembled using wood or metal beams to create a framework to begin layering adobe bricks. Depending on the thickness of the adobe bricks, the framework has been preformed using a steel framing and a layering of a metal fencing or wiring over the framework to allow an even load as masses of adobe are spread across the metal fencing like cob and allowed to air dry accordingly. This method was demonstrated with an adobe blend heavily impregnated with cement to allow even drying and prevent cracking. The more traditional flat adobe roofs are functional only in dry climates that are not exposed to snow loads. The heaviest wooden beams, called vigas, lie atop the wall. Across the vigas lie smaller members called latillas and upon those brush is then laid. Finally, the adobe layer is applied. To construct a flat adobe roof, beams of wood were laid to span the building, the ends of which were attached to the tops of the walls. Once the vigas, latillas and brush are laid, adobe bricks are placed. An adobe roof is often laid with bricks slightly larger in width to ensure a greater expanse is covered when placing the bricks onto the roof. Following each individual brick should be a layer of adobe mortar, recommended to be at least 25 mm (1 in) thick to make certain there is ample strength between the brick’s edges and also to provide a relative moisture barrier during rain. Roof design evolved around 1850 in the American Southwest. Three inches of adobe mud was applied on top of the latillas, then 18 inches of dry adobe dirt applied to the roof. The dirt was contoured into a low slope to a downspout aka a 'canal'. When moisture was applied to the roof the clay particles expanded to create a waterproof membrane. Once a year it was necessary to pull the weeds from the roof and reslope the dirt as needed.Depending on the materials, adobe roofs can be inherently fire-proof. The construction of a chimney can greatly influence the construction of the roof supports, creating an extra need for care in choosing the materials. The builders can make an adobe chimney by stacking simple adobe bricks in a similar fashion as the surrounding walls. == Adobe around the world == The largest structure ever made from adobe is the Arg-é Bam built by the Achaemenid Empire. Other large adobe structures are the Huaca del Sol in Peru, with 100 million signed bricks and the ciudellas of Chan Chan and Tambo Colorado, both in Peru. == See also == Alker Cob (building) Compressed earth block Earth structure Hassan Fathy Mudbrick Qadad (waterproofing plaster) Qalat (fortress) Rammed earth San Xavier del Bac Sod house Super Adobe Wattle and daub Cas di torto Monterey Colonial architecture used adobe walls Ctesiphon Arch in Iraq is the largest mud brick arch in the world built beginning in 540 AD == References == == External links == Building With Awareness A detailed how-to DVD video that shows adobe wall construction and their use as thermal mass walls Cal-Earth (The California Institute of Earth Art and Architecture) has developed a patented system called Superadobe, in which bags filled with stabilized earth are layered with strands of barbed wire to form a structure strong enough to withstand earthquakes, fire and flood.

### Instruction: retrieve labels for this: An adventure is an exciting experience that is typically a bold, sometimes risky, undertaking. Adventures may be activities with some potential for physical danger such as traveling, exploring, skydiving, mountain climbing, scuba diving, river rafting or participating in extreme sports. == Motivation == Adventurous experiences create psychological arousal, which can be interpreted as negative (e.g. fear) or positive (e.g. flow). For some people, adventure becomes a major pursuit in and of itself. According to adventurer André Malraux, in his La Condition Humaine (1933), "If a man is not ready to risk his life, where is his dignity?". Similarly, Helen Keller stated that "Life is either a daring adventure or nothing."Outdoor adventurous activities are typically undertaken for the purposes of recreation or excitement: examples are adventure racing and adventure tourism. Adventurous activities can also lead to gains in knowledge, such as those undertaken by explorers and pioneers – the British adventurer Jason Lewis, for example, uses adventures to draw global sustainability lessons from living within finite environmental constraints on expeditions to share with schoolchildren. Adventure education intentionally uses challenging experiences for learning. == Adventure in mythology and fiction == Some of the oldest and most widespread stories in the world are stories of adventure such as Homer's The Odyssey.The knight errant was the form the "adventure seeker" character took in the late Middle Ages. The adventure novel exhibits these "protagonist on adventurous journey" characteristics as do many popular feature films, such as Star Wars and Raiders of the Lost Ark. === Outdoors === Adventure books may have the theme of the hero or main character going to face the wilderness or Mother Nature. Examples include books such as Hatchet or My Side of the Mountain. These books are less about "questing", such as in mythology or other adventure novels, but more about surviving on their own, living off the land, gaining new experiences, and becoming closer to the natural world. === Questing === Many adventures are based on the idea of a quest: the hero goes off in pursuit of a reward, whether it be a skill, prize, or perhaps the safety of a person. On the way, the hero must overcome various obstacles. Mythologist Joseph Campbell discussed his notion of the monomyth in his book, The Hero with a Thousand Faces. Campbell proposed that the heroic mythological stories from culture to culture followed a similar underlying pattern, starting with the "call to adventure", followed by a hazardous journey, and eventual triumph. === Video games === Many video games are adventure games. == Adventure in nonfiction == From ancient times, travelers and explorers have written about their adventures. Journals which became best-sellers in their day were written, such as Marco Polo's journal The Travels of Marco Polo or Mark Twain's Roughing It. Others were personal journals, only later published, such as the journals of Lewis and Clark or Captain James Cook's journals. There are also books written by those not directly a part of the adventure in question, such as The Right Stuff by Tom Wolfe, or books written by those participating in the adventure but in a format other than that of a journal, such as Conquistadors of the Useless by Lionel Terray. Documentaries often use the theme of adventure as well. == Adventure sports == There are many sports classified as adventure sports, due to their inherent danger and excitement. Some of these include mountain climbing, skydiving, or other extreme sports. == See also == List of genres Exploration Tourism Travel Sports Adventure travel == References == == External links == Website of the Research Unit "Philology of Adventure": ongoing research project on the literary history of the adventure pattern What is an adventure?

### Instruction: retrieve labels for this: Aruba ( ə-ROO-bə; Dutch: [aːˈrubaː], Papiamento: [aˈruba]) is an island and a constituent country of the Kingdom of the Netherlands in the southern Caribbean Sea, located about 1,600 kilometres (990 mi) west of the main part of the Lesser Antilles and 29 kilometres (18 mi) north of the coast of Venezuela. It measures 32 kilometres (20 mi) long from its northwestern to its southeastern end and 10 kilometres (6 mi) across at its widest point. Together with Bonaire and Curaçao, Aruba forms a group referred to as the ABC islands. Collectively, Aruba and the other Dutch islands in the Caribbean are often called the Dutch Caribbean. Aruba is one of the four countries that form the Kingdom of the Netherlands, along with the Netherlands, Curaçao, and Sint Maarten; the citizens of these countries are all Dutch nationals. Aruba has no administrative subdivisions, but, for census purposes, is divided into eight regions. Its capital is Oranjestad. Unlike much of the Caribbean region, Aruba has a dry climate and an arid, cactus-strewn landscape. This climate has helped tourism as visitors to the island can reliably expect warm, sunny weather. It has a land area of 179 km2 (69.1 sq mi) and is densely populated, with a total of 102,484 inhabitants at the 2010 Census. It lies outside Hurricane Alley. == Etymology == The name Aruba may have different origins: From the Spanish Oro hubo which means "there was gold" From the Indian word Oruba which means "well-placed" From the Indian words Ora ("shell") and Oubao ("island") == History == Aruba's first inhabitants are thought to have been Caquetío Amerindians from the Arawak tribe, who migrated there from Venezuela to escape attacks by the Caribs. Fragments of the earliest known Indian settlements date back to 1000 AD. As sea currents made canoe travel to other Caribbean islands difficult, Caquetio culture remained more closely associated with that of mainland South America. Europeans first learned of Aruba following the explorations for Spain by Amerigo Vespucci and Alonso de Ojeda in the summer of 1499. Both described Aruba as an "island of giants", remarking on the comparatively large stature of the native Caquetíos compared to Europeans. Gold was not discovered on Aruba for another 300 years. Vespucci returned to Spain with stocks of cotton and brazilwood from the island and described houses built into the ocean. Vespucci and Ojeda's tales spurred interest in Aruba, and Spaniards soon colonized the island.Because it had low rainfall, Aruba was not considered profitable for the plantation system and the economics of the slave trade.Aruba was colonized by Spain for over a century. Simas, the Cacique, or chief, in Aruba, welcomed the first Catholic priests in Aruba, who gave him a wooden cross as a gift. In 1508, the Spanish Crown appointed Alonso de Ojeda as its first Governor of Aruba, as part of Nueva Andalucía. Arawaks spoke the "broken Spanish" which their ancestors had learned on Hispaniola.Another governor appointed by Spain was Juan Martínez de Ampiés. A cédula real decreed in November 1525 gave Ampiés, factor of Española, the right to repopulate Aruba. In 1528, Ampiés was replaced by a representative of the House of Welser of Augsburg. The Netherlands seized Aruba from Spain in 1636 in the course of the Thirty Years' War. Since 1636, Aruba has been under Dutch administration, initially governed by Peter Stuyvesant, later appointed to New Amsterdam (New York City). Stuyvesant was on a special mission in Aruba in November and December 1642. The island was included under the Dutch West India Company (W.I.C.) administration, as "New Netherland and Curaçao", from 1648 to 1664. In 1667 the Dutch administration appointed an Irishman as "Commandeur" in Aruba. The Dutch took control 135 years after the Spanish, leaving the Arawaks to farm and graze livestock, and used the island as a source of meat for other Dutch possessions in the Caribbean. Aruba's proximity to South America resulted in interaction with cultures of the coastal areas more than a century after independence of Netherlands from Spain; architectural similarities can be seen between the 19th-century parts of Oranjestad and the nearby Venezuelan city of Coro in Falcón State. Historically, Dutch was not widely spoken on the island outside of colonial administration; its use increased in the late 19th and early 20th centuries. Students on Curaçao, Aruba, and Bonaire were taught predominantly in Spanish until the late 19th century, when the British took Curaçao, Aruba, and Bonaire. Teaching of Spanish was restored when Dutch rule resumed in 1815. Also, efforts were made to introduce bilingual popular education in Dutch and Papiamentu in the late 19th century.During the Napoleonic wars, the British Empire took control over the island, between 1799 and 1802, and between 1804 and 1816, before handing it back to the Dutch.During World War II with the occupation of the Netherlands in 1940 the oil facilities in Aruba came under the administration of the Dutch government-in-exile in London, and Aruba continued to supply oil to the British and their allies. === Move towards independence === In August 1947, Aruba presented its first Staatsreglement (constitution), for Aruba's status aparte as an autonomous state within the Kingdom of the Netherlands. By 1954, the Charter of the Kingdom of the Netherlands was established, providing a framework for relations between Aruba and the rest of the Kingdom.In 1972, at a conference in Suriname, Betico Croes (MEP), a politician from Aruba, proposed a sui-generis Dutch Commonwealth of four states: Aruba, the Netherlands, Suriname and the Netherlands Antilles, each to have its own nationality. C. Yarzagaray, a parliamentary member representing the AVP political party, proposed a referendum so that the people of Aruba could choose whether they wanted total independence or Status Aparte as a full autonomous state under the Crown. Croes worked in Aruba to inform and prepare the people of Aruba for independence. In 1976, he appointed a committee that chose the national flag and anthem, introducing them as symbols of Aruba's sovereignty and independence. He set 1981 as a target date for independence. In March 1977, the first Referendum for Self Determination was held with the support of the United Nations; 82% of the participants voted for independence.The Island Government of Aruba assigned the Institute of Social Studies in The Hague to prepare a study for independence; it was titled Aruba en Onafhankelijkheid, achtergronden, modaliteiten en mogelijkheden; een rapport in eerste aanleg (Aruba and independence, backgrounds, modalities and opportunities; a preliminary report) (1978). At the conference in The Hague in 1981, Aruba's independence was set for the year 1991. In March 1983, Aruba reached an official agreement within the Kingdom for its independence, to be developed in a series of steps as the Crown granted increasing autonomy. In August 1985 Aruba drafted a constitution that was unanimously approved. On 1 January 1986, after elections were held for its first parliament, Aruba seceded from the Netherlands Antilles; it officially became a country of the Kingdom of the Netherlands. Full independence was projected in 1996. After his death in 1986, Croes was proclaimed Libertador di Aruba. At a convention in The Hague in 1990, at the request of Aruba's Prime Minister, the governments of Aruba, the Netherlands, and the Netherlands Antilles postponed indefinitely its transition to full independence. The article scheduling Aruba's complete independence was rescinded in 1995, although the process could be revived after another referendum. == Geography == Aruba is a generally flat, riverless island in the Leeward Antilles island arc of the Lesser Antilles in the southern part of the Caribbean. It has white sandy beaches on the western and southern coasts of the island, relatively sheltered from fierce ocean currents. This is where most tourist development has occurred. The northern and eastern coasts, lacking this protection, are considerably more battered by the sea and have been left largely untouched by humans. The hinterland of the island features some rolling hills, the best known of which are called Hooiberg at 165 meters (541 ft) and Mount Jamanota, the highest on the island at 188 meters (617 ft) above sea level. Oranjestad, the capital, is located at 12°19′N 70°1′W. To the east of Aruba are Bonaire and Curaçao, two island territories which once formed the southwest part of the Netherlands Antilles. This group of islands is sometimes called the ABC islands. They are located on the South American continental shelf and therefore geographically listed as part of South America. The Natural Bridge was a large, naturally formed limestone bridge on the island's north shore. It was a popular tourist destination until its collapse in 2005. === Cities and towns === The island, with a population of just over 100,000 inhabitants, does not have major cities. The island is divided into six districts. Most of the island's population resides in or around the two major city-like districts of Oranjestad (Capital) and San Nicolaas. Oranjestad and San Nicolaas are both divided into two districts for census purposes only. The districts are as follows: Noord Oranjestad Paradera San Nicolaas Santa Cruz Savaneta === Fauna === The island of Aruba, being isolated from the main land of South America, has fostered the evolution of multiple endemic animals. The island provides a habitat for the endemic Aruban Whiptail and Aruba Rattlesnake, as well as an endemic subspecies of Burrowing Owl and Brown-throated Parakeet. The rattlesnake and the owl are printed on the Aruban currency. === Flora === The flora of Aruba differs from the typical tropical island vegetation. Xeric scrublands are common, with various forms of cacti, thorny shrubs, and evergreens. The most known plant is the Aloe vera, which has a place on the Coat of Arms of Aruba. === Climate === By the Köppen climate classification, Aruba has a hot semi-arid climate (Köppen BSh). Mean monthly temperature in Oranjestad varies little from 26.7 °C (80.1 °F) to 29.2 °C (84.6 °F), moderated by constant trade winds from the Atlantic Ocean, which come from the north-east. Yearly rainfall barely exceeds 470 millimetres or 18.5 inches in Oranjestad, although it is extremely variable and can range from as little as 150 millimetres or 5.91 inches during strong El Niño years (e.g. 1911/1912, 1930/1931, 1982/1983, 1997/1998) to over 1,000 millimetres or 39.37 inches in La Niña years like 1933/1934, 1970/1971 or 1988/1989. == Demographics == In terms of nationality, the population is estimated to be 82.1% Dutch, 6.6% Colombian, 2.2% Venezuelan, 2.2% Dominican, 1.2% Haitian, 0.1% unspecified.In terms of ethnic composition, the population is estimated to be 75% mixed European/Amerindian/African, 15% Black and 10% other ethnicities. The Arawak heritage is stronger on Aruba than on most Caribbean islands, and a quite big portion of Arubans who claim their ethnicity as Dutch possess Arawak blood. Although no full-blooded Aboriginals remain, the features of the islanders clearly indicate their genetic Arawak heritage. Most of the population is descended from Caquetio Indians and Dutch and to a lesser extent of Africans, Spanish, Portuguese, English, French, and Sephardic Jewish ancestors. Aruba is a home of Chinese, and Indo Caribbeans and Javanese, who descend largely from workers contracted from India and the island of Java in the former Dutch East Indies (modern Indonesia).Recently, there has been substantial immigration to the island from neighboring American and Caribbean nations, possibly attracted by the higher paid jobs. In 2007, new immigration laws were introduced to help control the growth of the population by restricting foreign workers to a maximum of three years residency on the island. Demographically, Aruba has felt the impact of its proximity to Venezuela. Many of Aruba's families are descended from Venezuelan immigrants. There is a seasonal increase of Venezuelans living in second homes. As Aruba has a little proximity to Colombia, Colombian residents and their children are found here. === Language === The official languages are Dutch and Papiamento. However, Dutch is the sole language for all administration and legal matters, Papiamento is the predominant language on Aruba. It is a creole language, spoken on Aruba, Bonaire, and Curaçao, that incorporates words from Portuguese, West African languages, Dutch, and Spanish. English is known by many; its usage has grown due to tourism. Other common languages spoken, based on the size of their community, are Portuguese, Chinese, German, Spanish, and French. In recent years, the government of Aruba has shown an increased interest in acknowledging the cultural and historical importance of its native language. Although spoken Papiamento is fairly similar among the several Papiamento-speaking islands, there is a big difference in written Papiamento. The orthography differs per island and even per group of people. Some are more oriented towards Portuguese and use the equivalent spelling (e.g. "y" instead of "j"), where others are more oriented towards Dutch. The book The Buccaneers of America, first published in 1678, states through eyewitness account that the natives on Aruba spoke Spanish already. Spanish became an important language in the 18th century due to the close economic ties with Spanish colonies in what are now Venezuela and Colombia, and several Venezuelan TV networks are received, and the fact that Aruba has a presence of Venezuelan and Colombian residents. The oldest government official statement written in Papiamento dates from 1803. Around 12.6% of the population today speaks Spanish. Use of English dates to the early 19th century, when the British took Curaçao, Aruba and Bonaire. When Dutch rule resumed in 1815, officials already noted wide use of the language.Aruba has four newspapers published in Papiamento: Diario, Bon Dia, Solo di Pueblo and Awe Mainta; and three in English: Aruba Daily, Aruba Today and The News. Amigoe is a newspaper published in Dutch. Aruba also has 18 radio stations (two AM and 16 FM) and two local television stations (Telearuba, and Channel 22). Aruba is a polyglot society. Most of Aruba's population is able to converse in at least two of the languages of Papiamentu, Dutch, English, and Spanish. === Religion === Three-quarters of the population is Roman Catholic. === Regions === For census purposes, Aruba is divided into eight regions, which have no administrative functions: == Government == As a constituent country of the Kingdom of the Netherlands, Aruba's politics take place within a framework of a 21-member Parliament and an eight-member Cabinet. The governor of Aruba is appointed for a six-year term by the monarch, and the prime minister and deputy prime minister are elected by the Staten (or "Parlamento") for four-year terms. The Staten is made up of 21 members elected by direct, popular vote to serve a four-year term.Together with the Netherlands, the countries of Aruba, Curaçao and Sint Maarten form the Kingdom of the Netherlands. As they share the same Dutch citizenship, these four countries still also share the Dutch passport as the Kingdom of the Netherlands passport. As Aruba, Curaçao and Sint Maarten have small populations, the three countries had to limit immigration. To protect their population, they have the right to control the admission and expulsion of people from the Netherlands. Aruba is designated as a member of the Overseas Countries and Territories (OCT) and is thus officially not a part of the European Union, though Aruba can and does receive support from the European Development Fund. === Politics === The Aruban legal system is based on the Dutch model. In Aruba, legal jurisdiction lies with the Gerecht in Eerste Aanleg (Court of First Instance) on Aruba, the Gemeenschappelijk Hof van Justitie van Aruba, Curaçao, Sint Maarten en van Bonaire, Sint Eustatius en Saba (Joint Court of Justice of Aruba, Curaçao, Sint Maarten, and of Bonaire, Sint Eustatius and Saba) and the Hoge Raad der Nederlanden (Supreme Court of Justice of the Netherlands). The Korps Politie Aruba (Aruba Police Force) is the island's law enforcement agency and operates district precincts in Oranjestad, Noord, San Nicolaas, and Santa Cruz, where it is headquartered.Deficit spending has been a staple in Aruba's history, and modestly high inflation has been present as well. By 2006, the government's debt had grown to 1.883 billion Aruban florins. Aruba received some development aid from the Dutch government each year through 2009, as part of a deal (signed as "Aruba's Financial Independence") in which the Netherlands gradually reduced its financial help to the island each successive year. In 2006, the Aruban government changed several tax laws to reduce the deficit. Direct taxes have been converted to indirect taxes as proposed by the IMF. A 3% tax has been introduced on sales and services, while income taxes have been lowered and revenue taxes for business reduced by 20%. The government compensated workers with 3.1% for the effect that the B.B.O. would have on the inflation for 2007. == Education == Aruba's educational system is patterned after the Dutch system of education.The Government of Aruba finances the public national education system.There are mostly public schools, and there are private schools, including the International School of Aruba and Schakel College.There are two medical schools, Aureus University School of Medicine and Xavier University School of Medicine, as well as its own national university, the University of Aruba. == Economy == Aruba has one of the highest standards of living in the Caribbean region. There is a low unemployment rate.The GDP per capita for Aruba was estimated to be $28,924 in 2014; among the highest in the Caribbean and the Americas. Its main trading partners are Colombia, the United States, Venezuela, and the Netherlands. The island's economy has been dominated by three main industries: tourism, aloe export, and petroleum refining (The Lago Oil and Transport Company and the Arend Petroleum Maatschappij Shell Co.). Before the "Status Aparte" (a separate completely autonomous country/state within the Kingdom), oil processing was the dominant industry in Aruba despite expansion of the tourism sector. Today, the influence of the oil processing business is minimal. The size of the agriculture and manufacturing sectors also remains minimal. Aloe was introduce to Aruba in 1840 but did not become a big export till 1890. Cornelius Eman founded Aruba Aloe Balm and the industry had become very important to the economy. At one point two thirds of the island was covered in Aloe Vera fields and the first plantation covered 150 acres and it is still used today at 127 years old. Aruba had become the largest exporter of aloe in the world, also because of Aruba's climate and dry soil the aloe plants flourished and the aloin content was twenty two percent while the aloin content in the rest of the world was only as high as fifteen percent (arubablog.net) From this Aruba now has its own line of aloe and that contains skin care products, deodorant, sun care, shower and hair products (Aruba aloe). The official exchange rate of the Aruban florin is pegged to the US dollar at 1.79 florins to 1 USD. Because of this fact, and due to a large number of American tourists, many businesses operate using US dollars instead of florins, especially in the hotel and resort districts. === Tourism === About three quarters of the Aruban gross national product is earned through tourism or related activities. Most tourists are from the United States (predominantly from the north-east US), Canada, the Netherlands and South America, mainly Venezuela and Colombia.As part of the Kingdom of the Netherlands, citizens of the Netherlands can travel with relative ease to Aruba and other islands of the Dutch Antilles. No visas are needed for Dutch citizens, only a passport, and although the currency used in Aruba is different (the Netherlands uses the Euro), money can be easily exchanged at a local bank for Aruban Florins. For the facilitation of the passengers whose destination is the United States, the United States Department of Homeland Security (DHS), U.S. Customs and Border Protection (CBP) full pre-clearance facility in Aruba has been in effect since 1 February 2001 with the expansion in the Queen Beatrix Airport. United States and Aruba have had the agreement since 1986. It began as a USDA and Customs post. Since 2008, Aruba has been the only island to have this service for private flights. == Military == Defense on Aruba is the responsibility of the Kingdom of the Netherlands. The Netherlands Military forces that protect Aruba include the Royal Netherlands Navy, the Netherlands Marine Corps and the Netherlands Coastguard. There is also a small indigenous "Arubaanse Militie" (ARUMIL) of about platoon strength. All forces are stationed at Marines Barracks Savaneta. Furthermore, in 1999 the U.S. Department of Defense established a Forward Operating Location (FOL) at the airport. == Culture == On 18 March, Aruba celebrates its National Day. In 1976, Aruba presented its National Anthem (Aruba Dushi Tera) and Flag. Aruba has a varied culture. According to the Bureau Burgelijke Stand en Bevolkingsregister (BBSB), in 2005 there were ninety-two different nationalities living on the island. Dutch influence can still be seen, as in the celebration of "Sinterklaas" on 5 and 6 December and other national holidays like 27 April, when in Aruba and the rest of the Kingdom of the Netherlands the King's birthday or "Dia di Rey" (Koningsdag) is celebrated. Christmas and New Year's Eve are celebrated with the typical music and songs for gaitas for Christmas and the Dande for New Year, and ayaca, ponche crema, ham, and other typical foods and drinks. Millions of florins worth of fireworks are burnt at midnight on New Year's Eve. On 25 January, Betico Croes' birthday is celebrated. Dia di San Juan is celebrated on 24 June. Besides Christmas, the religious holy days of the Feast of the Ascension and Good Friday are holidays on the island. The holiday of Carnaval is also an important one in Aruba, as it is in many Caribbean and Latin American countries, and, like Mardi Gras, that goes on for weeks. Its celebration in Aruba started, around the 1950s, influenced by the inhabitants from Venezuela and the nearby islands (Curaçao, St. Vincent, Trinidad, Barbados, St. Maarten and Anguilla) who came to work for the Oil refinery. Over the years the Carnival Celebration has changed and now starts from the beginning of January till the Tuesday before Ash Wednesday with a large parade on the last Sunday of the festivities (Sunday before Ash Wednesday). Tourism from the United States has recently increased the visibility of American culture on the island, with such celebrations as Halloween and Thanksgiving Day in November. == Infrastructure == Aruba's Queen Beatrix International Airport is located near Oranjestad. According to the Aruba Airport Authority, almost 1.7 million travelers used the airport in 2005, 61% of whom were Americans. Aruba has two ports, Barcadera and Playa, which are located in Oranjestad and Barcadera. The Port of Playa services all the cruise-ship lines, including Royal Caribbean, Carnival Cruise Lines, NCL, Holland America Line, Disney Cruise Line and others. Nearly one million tourists enter this port per year. Aruba Ports Authority, owned and operated by the Aruban government, runs these seaports. Arubus is a government-owned bus company. Its buses operate from 3:30 a.m. until 12:30 a.m., 365 days a year. Small private vans also provide transportation services in certain areas such Hotel Area, San Nicolaas, Santa Cruz and Noord. A street car service runs on rails on the Mainstreet. === Utilities === Water-en Energiebedrijf Aruba, N.V. (W.E.B.) produces potable industrial water at the world's third largest desalination plant. Average daily consumption in Aruba is about 37,000 long tons (38,000 t). === Communications === There are two telecommunications providers: Setar, a government-based company and Digicel, both of which are privately owned. Setar is the provider of services such as internet, video conferencing, GSM wireless technology and land lines. Digicel is Setar's competitor in wireless technology using the GSM platform. == Places of interest == == Notable people == Xander Bogaerts, MLB shortstop of the Boston Red Sox Betico Croes, political activist Henny Eman, first prime minister of Aruba Bobby Farrell, musician Dave Benton, Aruban-Estonian musician Jossy Mansur, editor of the Papiamento language newspaper, Diario Nelson Oduber, prime minister Sidney Ponson, MLB pitcher Fredis Refunjol, governor Julia Renfro, newspaper editor and photographer Jeannette Richardson-Baars, Deputy Police Commissioner == See also == Bibliography of Aruba Central Bank of Aruba Index of Aruba-related articles List of monuments of Aruba Military of Aruba Outline of Aruba SS Pedernales == References == == External links == Aruba.com – official tourism site of Aruba Aruba at Curlie (based on DMOZ) Wikimedia Atlas of Aruba Aruba Esso News from the National Library of Aruba, openly and freely available in the Digital Library of the Caribbean ### Answer: <Aruba>, <Countries in the Caribbean>, <Dependent territories in North America>, <Dutch-speaking countries and territories>, <Former Dutch colonies>, <Island countries>, <Islands of the Netherlands Antilles>, <Kingdom of the Netherlands>, <Lesser Antilles>, <Special territories of the European Union>, <States and territories established in 1986>

### Instruction: retrieve labels for this: The Articles of Confederation, formally the Articles of Confederation and Perpetual Union, was an agreement among the 13 original states of the United States of America that served as its first constitution. It was approved, after much debate (between July 1776 and November 1777), by the Second Continental Congress on November 15, 1777, and sent to the states for ratification. The Articles of Confederation came into force on March 1, 1781, after being ratified by all 13 states. A guiding principle of the Articles was to preserve the independence and sovereignty of the states. The federal government received only those powers which the colonies had recognized as belonging to king and parliament.The Articles formed a war-time confederation of states, with an extremely limited central government. While unratified, the document was used by the Congress to conduct business, direct the American Revolutionary War, conduct diplomacy with foreign nations, and deal with territorial issues and Native American relations. The adoption of the Articles made few perceptible changes in the federal government, because it did little more than legalize what the Continental Congress had been doing. That body was renamed the Congress of the Confederation; but Americans continued to call it the Continental Congress, since its organization remained the same.As the Confederation Congress attempted to govern the continually growing American states, delegates discovered that the limitations placed upon the central government rendered it ineffective at doing so. As the government's weaknesses became apparent, especially after Shays' Rebellion, individuals began asking for changes to the Articles. Their hope was to create a stronger national government. Initially, some states met to deal with their trade and economic problems. However, as more states became interested in meeting to change the Articles, a meeting was set in Philadelphia on May 25, 1787. This became the Constitutional Convention. It was quickly realized that changes would not work, and instead the entire Articles needed to be replaced. On March 4, 1789, the government under the Articles was replaced with the federal government under the Constitution. The new Constitution provided for a much stronger federal government by establishing a chief executive (the President), courts, and taxing powers. == Background and context == The political push to increase cooperation among the then-loyal colonies began with the Albany Congress in 1754 and Benjamin Franklin's proposed Albany Plan, an inter-colonial collaboration to help solve mutual local problems. The Articles of Confederation would bear some resemblance to it. Over the next two decades, some of the basic concepts it addressed would strengthen and others would weaken, particularly the degree of deserved loyalty to the crown. With civil disobedience resulting in coercive, and what the colonials perceived as intolerable acts of Parliament, and armed conflict resulting in dissidents being proclaimed rebels and outside the King's protection, any loyalty remaining shifted toward independence and how to achieve it. In 1775, with events outpacing communications, the Second Continental Congress began acting as the provisional government that would run the American Revolutionary War and gain the colonies their collective independence. It was an era of constitution writing—most states were busy at the task—and leaders felt the new nation must have a written constitution, even though other nations did not. During the war, Congress exercised an unprecedented level of political, diplomatic, military and economic authority. It adopted trade restrictions, established and maintained an army, issued fiat money, created a military code and negotiated with foreign governments.To transform themselves from outlaws into a legitimate nation, the colonists needed international recognition for their cause and foreign allies to support it. In early 1776, Thomas Paine argued in the closing pages of the first edition of Common Sense that the "custom of nations" demanded a formal declaration of American independence if any European power were to mediate a peace between the Americans and Great Britain. The monarchies of France and Spain in particular could not be expected to aid those they considered rebels against another legitimate monarch. Foreign courts needed to have American grievances laid before them persuasively in a "manifesto" which could also reassure them that the Americans would be reliable trading partners. Without such a declaration, Paine concluded, "[t]he custom of all courts is against us, and will be so, until, by an independence, we take rank with other nations."Beyond improving their existing association, the records of the Second Continental Congress show that the need for a declaration of independence was intimately linked with the demands of international relations. On June 7, 1776, Richard Henry Lee introduced a resolution before the Continental Congress declaring the colonies independent; at the same time he also urged Congress to resolve "to take the most effectual measures for forming foreign Alliances" and to prepare a plan of confederation for the newly independent states. Congress then created three overlapping committees to draft the Declaration, a Model Treaty, and the Articles of Confederation. The Declaration announced the states' entry into the international system; the model treaty was designed to establish amity and commerce with other states; and the Articles of Confederation, which established "a firm league" among the thirteen free and independent states, constituted an international agreement to set up central institutions for the conduct of vital domestic and foreign affairs. == Drafting == On June 12, 1776, a day after appointing a committee to prepare a draft of the Declaration of Independence, the Second Continental Congress resolved to appoint a committee of 13 to prepare a draft of a constitution for a union of the states. The committee met repeatedly, and chairman John Dickinson presented their results to the Congress on July 12, 1776. There were long debates on such issues as sovereignty, the exact powers to be given the confederate government, whether to have a judiciary, and voting procedures. The final draft of the Articles was prepared in the summer of 1777 and the Second Continental Congress approved them for ratification by the individual states on November 15, 1777, after a year of debate. Consensus was achieved by dividing sovereignty between the states and the central government, with a unicameral legislature that protected the liberty of the individual states. == Ratification == The Articles of Confederation was submitted to the states for ratification in November 1777. The first state to ratify was Virginia on December 16, 1777; 12 states had ratified the Articles by February 1779, 14 months into the process. The lone holdout, Maryland, refused to go along until the landed states, especially Virginia, had indicated they were prepared to cede their claims west of the Ohio River to the Union. It would be two years before the Maryland General Assembly became satisfied that the various states would follow through, and voted to ratify. During this time, Congress observed the Articles as its de facto frame of government. Maryland finally ratified the Articles on February 2, 1781. Congress was informed of Maryland's assent on March 1, and officially proclaimed the Articles of Confederation to be the law of the land.The several states ratified the Articles of Confederation on the following dates: == Article summaries == The Articles of Confederation contain a preamble, thirteen articles, a conclusion, and a signatory section. The individual articles set the rules for current and future operations of the confederation's central government. Under the Articles, the states retained sovereignty over all governmental functions not specifically relinquished to the national Congress, which was empowered to make war and peace, negotiate diplomatic and commercial agreements with foreign countries, and to resolve disputes between the states. The document also stipulates that its provisions "shall be inviolably observed by every state" and that "the Union shall be perpetual". Summary of the purpose and content of each of the 13 articles: Establishes the name of the confederation with these words: "The stile of this confederacy shall be 'The United States of America.'" Asserts the sovereignty of each state, except for the specific powers delegated to the confederation government: "Each state retains its sovereignty, freedom, and independence, and every power, jurisdiction, and right, which is not by this Confederation expressly delegated." Declares the purpose of the confederation: "The said States hereby severally enter into a firm league of friendship with each other, for their common defense, the security of their liberties, and their mutual and general welfare, binding themselves to assist each other, against all force offered to, or attacks made upon them, or any of them, on account of religion, sovereignty, trade, or any other pretense whatever." Elaborates upon the intent "to secure and perpetuate mutual friendship and intercourse among the people of the different States in this union," and to establish equal treatment and freedom of movement for the free inhabitants of each state to pass unhindered between the states, excluding "paupers, vagabonds, and fugitives from justice." All these people are entitled to equal rights established by the state into which they travel. If a crime is committed in one state and the perpetrator flees to another state, he will be extradited to and tried in the state in which the crime was committed. Allocates one vote in the Congress of the Confederation (the "United States in Congress Assembled") to each state, which is entitled to a delegation of between two and seven members. Members of Congress are to be appointed by state legislatures. No congressman may serve more than three out of any six years. Only the central government may declare war, or conduct foreign political or commercial relations. No state or official may accept foreign gifts or titles, and granting any title of nobility is forbidden to all. No states may form any sub-national groups. No state may tax or interfere with treaty stipulations already proposed. No state may wage war without permission of Congress, unless invaded or under imminent attack on the frontier; no state may maintain a peacetime standing army or navy, unless infested by pirates, but every State is required to keep ready, a well-trained, disciplined, and equipped militia. Whenever an army is raised for common defense, the state legislatures shall assign military ranks of colonel and below. Expenditures by the United States of America will be paid with funds raised by state legislatures, and apportioned to the states in proportion to the real property values of each. Powers and functions of the United States in Congress Assembled. Grants to the United States in Congress assembled the sole and exclusive right and power to determine peace and war; to exchange ambassadors; to enter into treaties and alliances, with some provisos; to establish rules for deciding all cases of captures or prizes on land or water; to grant letters of marque and reprisal (documents authorizing privateers) in times of peace; to appoint courts for the trial of pirates and crimes committed on the high seas; to establish courts for appeals in all cases of captures, but no member of Congress may be appointed a judge; to set weights and measures (including coins), and for Congress to serve as a final court for disputes between states. The court will be composed of jointly appointed commissioners or Congress shall appoint them. Each commissioner is bound by oath to be impartial. The court's decision is final. Congress shall regulate the post offices; appoint officers in the military; and regulate the armed forces. The United States in Congress assembled may appoint a president who shall not serve longer than one year per three-year term of the Congress. Congress may request requisitions (demands for payments or supplies) from the states in proportion with their population, or take credit. Congress may not declare war, enter into treaties and alliances, appropriate money, or appoint a commander in chief without nine states assented. Congress shall keep a journal of proceedings and adjourn for periods not to exceed six months. When Congress is in recess, any of the powers of Congress may be executed by "The committee of the states, or any nine of them", except for those powers of Congress which require nine states in Congress to execute. If "Canada" (as the British-held Province of Quebec was also known) accedes to this confederation, it will be admitted. No other colony could be admitted without the consent of nine states. Reaffirms that the Confederation accepts war debt incurred by Congress before the existence of the Articles. Declares that the Articles shall be perpetual, and may be altered only with the approval of Congress and the ratification of all the state legislatures. == Congress under the Articles == === The Army === Under the Articles, Congress had the authority to regulate and fund the Continental Army, but it lacked the power to compel the States to comply with requests for either troops or funding. This left the military vulnerable to inadequate funding, supplies, and even food. Further, although the Articles enabled the states to present a unified front when dealing with the European powers, as a tool to build a centralized war-making government, they were largely a failure; Historian Bruce Chadwick wrote: George Washington had been one of the very first proponents of a strong federal government. The army had nearly disbanded on several occasions during the winters of the war because of the weaknesses of the Continental Congress. ... The delegates could not draft soldiers and had to send requests for regular troops and militia to the states. Congress had the right to order the production and purchase of provisions for the soldiers, but could not force anyone to supply them, and the army nearly starved in several winters of war. The Continental Congress, before the Articles were approved, had promised soldiers a pension of half pay for life. However Congress had no power to compel the states to fund this obligation, and as the war wound down after the victory at Yorktown the sense of urgency to support the military was no longer a factor. No progress was made in Congress during the winter of 1783–84. General Henry Knox, who would later become the first Secretary of War under the Constitution, blamed the weaknesses of the Articles for the inability of the government to fund the army. The army had long been supportive of a strong union. Knox wrote: The army generally have always reprobated the idea of being thirteen armies. Their ardent desires have been to be one continental body looking up to one sovereign. ... It is a favorite toast in the army, "A hoop to the barrel" or "Cement to the Union". As Congress failed to act on the petitions, Knox wrote to Gouverneur Morris, four years before the Philadelphia Convention was convened, "As the present Constitution is so defective, why do not you great men call the people together and tell them so; that is, to have a convention of the States to form a better Constitution."Once the war had been won, the Continental Army was largely disbanded. A very small national force was maintained to man the frontier forts and to protect against Native American attacks. Meanwhile, each of the states had an army (or militia), and 11 of them had navies. The wartime promises of bounties and land grants to be paid for service were not being met. In 1783, George Washington defused the Newburgh conspiracy, but riots by unpaid Pennsylvania veterans forced Congress to leave Philadelphia temporarily.The Congress from time to time during the Revolutionary War requisitioned troops from the states. Any contributions were voluntary, and in the debates of 1788 the Federalists (who supported the proposed new Constitution) claimed that state politicians acted unilaterally, and contributed when the Continental army protected their state's interests. The Anti-Federalists claimed that state politicians understood their duty to the Union and contributed to advance its needs. Dougherty (2009) concludes that generally the States' behavior validated the Federalist analysis. This helps explain why the Articles of Confederation needed reforms. === Foreign policy === The 1783 Treaty of Paris, which ended hostilities with Great Britain, languished in Congress for several months because too few delegates were present at any one time to constitute a quorum so that it could be ratified. Afterward, the problem only got worse as Congress had no power to enforce attendance. Rarely did more than half of the roughly sixty delegates attend a session of Congress at the time, causing difficulties in raising a quorum. The resulting paralysis embarrassed and frustrated many American nationalists, including George Washington. Many of the most prominent national leaders, such as Washington, John Adams, John Hancock, and Benjamin Franklin, retired from public life, served as foreign delegates, or held office in state governments; and for the general public, local government and self-rule seemed quite satisfactory. This served to exacerbate Congress's impotence.Inherent weaknesses in the confederation's frame of government also frustrated the ability of the government to conduct foreign policy. In 1786, Thomas Jefferson, concerned over the failure of Congress to fund an American naval force to confront the Barbary pirates, wrote in a diplomatic correspondence to James Monroe that, "It will be said there is no money in the treasury. There never will be money in the treasury till the Confederacy shows its teeth."Furthermore, the 1786 Jay–Gardoqui Treaty with Spain also showed weakness in foreign policy. In this treaty, which was never ratified, the United States was to give up rights to use the Mississippi River for 25 years, which would have economically strangled the settlers west of the Appalachian Mountains. Finally, due to the Confederation's military weakness, it could not compel the British army to leave frontier forts which were on American soil — forts which, in 1783, the British promised to leave, but which they delayed leaving pending U.S. implementation of other provisions such as ending action against Loyalists and allowing them to seek compensation. This incomplete British implementation of the Treaty of Paris would later be resolved by the implementation of Jay's Treaty in 1795, after the federal Constitution came into force. === Taxation and commerce === Under the Articles of Confederation, the central government's power was kept quite limited. The Confederation Congress could make decisions, but lacked enforcement powers. Implementation of most decisions, including modifications to the Articles, required unanimous approval of all thirteen state legislatures.Congress was denied any powers of taxation: it could only request money from the states. The states often failed to meet these requests in full, leaving both Congress and the Continental Army chronically short of money. As more money was printed by Congress, the continental dollars depreciated. In 1779, George Washington wrote to John Jay, who was serving as the president of the Continental Congress, "that a wagon load of money will scarcely purchase a wagon load of provisions." Mr. Jay and the Congress responded in May by requesting $45 million from the States. In an appeal to the States to comply, Jay wrote that the taxes were "the price of liberty, the peace, and the safety of yourselves and posterity." He argued that Americans should avoid having it said "that America had no sooner become independent than she became insolvent" or that "her infant glories and growing fame were obscured and tarnished by broken contracts and violated faith." The States did not respond with any of the money requested from them. Congress had also been denied the power to regulate either foreign trade or interstate commerce and, as a result, all of the States maintained control over their own trade policies. The states and the Confederation Congress both incurred large debts during the Revolutionary War, and how to repay those debts became a major issue of debate following the War. Some States paid off their war debts and others did not. Federal assumption of the states' war debts became a major issue in the deliberations of the Constitutional Convention. === Accomplishments === Nevertheless, the Confederation Congress did take two actions with long-lasting impact. The Land Ordinance of 1785 and Northwest Ordinance created territorial government, set up protocols for the admission of new states and the division of land into useful units, and set aside land in each township for public use. This system represented a sharp break from imperial colonization, as in Europe, and it established the precedent by which the national (later, federal) government would be sovereign and expand westward—as opposed to the existing states doing so under their sovereignty.The Land Ordinance of 1785 established both the general practices of land surveying in the west and northwest and the land ownership provisions used throughout the later westward expansion beyond the Mississippi River. Frontier lands were surveyed into the now-familiar squares of land called the township (36 square miles), the section (one square mile), and the quarter section (160 acres). This system was carried forward to most of the States west of the Mississippi (excluding areas of Texas and California that had already been surveyed and divided up by the Spanish Empire). Then, when the Homestead Act was enacted in 1867, the quarter section became the basic unit of land that was granted to new settler-farmers. The Northwest Ordinance of 1787 noted the agreement of the original states to give up northwestern land claims, organized the Northwest Territory and laid the groundwork for the eventual creation of new states. While it didn't happen under the articles, the land north of the Ohio River and west of the (present) western border of Pennsylvania ceded by Massachusetts, Connecticut, New York, Pennsylvania, and Virginia, eventually became the states of: Ohio, Indiana, Illinois, Michigan, and Wisconsin, and the part of Minnesota east of the Mississippi River. The Northwest Ordinance of 1787 also made great advances in the abolition of slavery. New states admitted to the union in this territory would never be slave states. No new states were admitted to the Union under the Articles of Confederation. The Articles provided for a blanket acceptance of the Province of Quebec (referred to as "Canada" in the Articles) into the United States if it chose to do so. It did not, and the subsequent Constitution carried no such special provision of admission. Additionally, ordinances to admit Frankland (later modified to Franklin), Kentucky, and Vermont to the Union were considered, but none were approved. === Presidents of Congress === Under the Articles of Confederation, the presiding officer of Congress—referred to in many official records as President of the United States in Congress Assembled—chaired the Committee of the States when Congress was in recess, and performed other administrative functions. He was not, however, an executive in the way the later President of the United States is a chief executive, since all of the functions he executed were under the direct control of Congress.There were 10 presidents of Congress under the Articles. The first, Samuel Huntington, had been serving as president of the Continental Congress since September 28, 1779. == The U.S. under the Articles == The peace treaty left the United States independent and at peace but with an unsettled governmental structure. The Articles envisioned a permanent confederation, but granted to the Congress—the only federal institution—little power to finance itself or to ensure that its resolutions were enforced. There was no president, no executive agencies, no judiciary and no tax base. The absence of a tax base meant that there was no way to pay off state and national debts from the war years except by requesting money from the states, which seldom arrived. Although historians generally agree that the Articles were too weak to hold the fast-growing nation together, they do give credit to the settlement of the western issue, as the states voluntarily turned over their lands to national control.By 1783, with the end of the British blockade, the new nation was regaining its prosperity. However, trade opportunities were restricted by the mercantilism of the British and French empires. The ports of the British West Indies were closed to all staple products which were not carried in British ships. France and Spain established similar policies. Simultaneously, new manufacturers faced sharp competition from British products which were suddenly available again. Political unrest in several states and efforts by debtors to use popular government to erase their debts increased the anxiety of the political and economic elites which had led the Revolution. The apparent inability of the Congress to redeem the public obligations (debts) incurred during the war, or to become a forum for productive cooperation among the states to encourage commerce and economic development, only aggravated a gloomy situation. In 1786–87, Shays' Rebellion, an uprising of dissidents in western Massachusetts against the state court system, threatened the stability of state government.The Continental Congress printed paper money which was so depreciated that it ceased to pass as currency, spawning the expression "not worth a continental". Congress could not levy taxes and could only make requisitions upon the States. Less than a million and a half dollars came into the treasury between 1781 and 1784, although the governors had been asked for two million in 1783 alone.When John Adams went to London in 1785 as the first representative of the United States, he found it impossible to secure a treaty for unrestricted commerce. Demands were made for favors and there was no assurance that individual states would agree to a treaty. Adams stated it was necessary for the States to confer the power of passing navigation laws to Congress, or that the States themselves pass retaliatory acts against Great Britain. Congress had already requested and failed to get power over navigation laws. Meanwhile, each State acted individually against Great Britain to little effect. When other New England states closed their ports to British shipping, Connecticut hastened to profit by opening its ports.By 1787 Congress was unable to protect manufacturing and shipping. State legislatures were unable or unwilling to resist attacks upon private contracts and public credit. Land speculators expected no rise in values when the government could not defend its borders nor protect its frontier population.The idea of a convention to revise the Articles of Confederation grew in favor. Alexander Hamilton realized while serving as Washington's top aide that a strong central government was necessary to avoid foreign intervention and allay the frustrations due to an ineffectual Congress. Hamilton led a group of like-minded nationalists, won Washington's endorsement, and convened the Annapolis Convention in 1786 to petition Congress to call a constitutional convention to meet in Philadelphia to remedy the long-term crisis. == Signatures == The Second Continental Congress approved the Articles for distribution to the states on November 15, 1777. A copy was made for each state and one was kept by the Congress. On November 28, the copies sent to the states for ratification were unsigned, and the cover letter, dated November 17, had only the signatures of Henry Laurens and Charles Thomson, who were the President and Secretary to the Congress. The Articles, however, were unsigned, and the date was blank. Congress began the signing process by examining their copy of the Articles on June 27, 1778. They ordered a final copy prepared (the one in the National Archives), and that delegates should inform the secretary of their authority for ratification. On July 9, 1778, the prepared copy was ready. They dated it, and began to sign. They also requested each of the remaining states to notify its delegation when ratification was completed. On that date, delegates present from New Hampshire, Massachusetts, Rhode Island, Connecticut, New York, Pennsylvania, Virginia and South Carolina signed the Articles to indicate that their states had ratified. New Jersey, Delaware and Maryland could not, since their states had not ratified. North Carolina and Georgia also were unable to sign that day, since their delegations were absent. After the first signing, some delegates signed at the next meeting they attended. For example, John Wentworth of New Hampshire added his name on August 8. John Penn was the first of North Carolina's delegates to arrive (on July 10), and the delegation signed the Articles on July 21, 1778. The other states had to wait until they ratified the Articles and notified their Congressional delegation. Georgia signed on July 24, New Jersey on November 26, and Delaware on February 12, 1779. Maryland refused to ratify the Articles until every state had ceded its western land claims. Chevalier de La Luzerne, French Minister to the United States, felt that the Articles would help strengthen the American government. In 1780 when Maryland requested France provide naval forces in the Chesapeake Bay for protection from the British (who were conducting raids in the lower part of the bay), he indicated that French Admiral Destouches would do what he could but La Luzerne also “sharply pressed” Maryland to ratify the Articles, thus suggesting the two issues were related. On February 2, 1781, the much-awaited decision was taken by the Maryland General Assembly in Annapolis. As the last piece of business during the afternoon Session, "among engrossed Bills" was "signed and sealed by Governor Thomas Sim Lee in the Senate Chamber, in the presence of the members of both Houses... an Act to empower the delegates of this state in Congress to subscribe and ratify the articles of confederation" and perpetual union among the states. The Senate then adjourned "to the first Monday in August next." The decision of Maryland to ratify the Articles was reported to the Continental Congress on February 12. The confirmation signing of the Articles by the two Maryland delegates took place in Philadelphia at noon time on March 1, 1781, and was celebrated in the afternoon. With these events, the Articles were entered into force and the United States of America came into being as a sovereign federal state. Congress had debated the Articles for over a year and a half, and the ratification process had taken nearly three and a half years. Many participants in the original debates were no longer delegates, and some of the signers had only recently arrived. The Articles of Confederation and Perpetual Union were signed by a group of men who were never present in the Congress at the same time. === Signers === The signers and the states they represented were: Roger Sherman (Connecticut) was the only person to sign all four great state papers of the United States: the Continental Association, the United States Declaration of Independence, the Articles of Confederation and the United States Constitution. Robert Morris (Pennsylvania) signed three of the great state papers of the United States: the United States Declaration of Independence, the Articles of Confederation and the United States Constitution. John Dickinson (Delaware), Daniel Carroll (Maryland) and Gouverneur Morris (New York), along with Sherman and Robert Morris, were the only five people to sign both the Articles of Confederation and the United States Constitution (Gouverneur Morris represented Pennsylvania when signing the Constitution). == Gallery == Images of an original draft of the Articles of Confederation stored at the United States National Archive. == Revision and replacement == On January 21, 1786, the Virginia Legislature, following James Madison's recommendation, invited all the states to send delegates to Annapolis, Maryland to discuss ways to reduce interstate conflict. At what came to be known as the Annapolis Convention, the few state delegates in attendance endorsed a motion that called for all states to meet in Philadelphia in May 1787 to discuss ways to improve the Articles of Confederation in a "Grand Convention." Although the states' representatives to the Constitutional Convention in Philadelphia were only authorized to amend the Articles, the representatives held secret, closed-door sessions and wrote a new constitution. The new Constitution gave much more power to the central government, but characterization of the result is disputed. The general goal of the authors was to get close to a republic as defined by the philosophers of the Age of Enlightenment, while trying to address the many difficulties of the interstate relationships. Historian Forrest McDonald, using the ideas of James Madison from Federalist 39, describes the change this way: The constitutional reallocation of powers created a new form of government, unprecedented under the sun. Every previous national authority either had been centralized or else had been a confederation of sovereign states. The new American system was neither one nor the other; it was a mixture of both. In May 1786, Charles Pinckney of South Carolina proposed that Congress revise the Articles of Confederation. Recommended changes included granting Congress power over foreign and domestic commerce, and providing means for Congress to collect money from state treasuries. Unanimous approval was necessary to make the alterations, however, and Congress failed to reach a consensus. The weakness of the Articles in establishing an effective unifying government was underscored by the threat of internal conflict both within and between the states, especially after Shays' Rebellion threatened to topple the state government of Massachusetts. Historian Ralph Ketcham comments on the opinions of Patrick Henry, George Mason, and other Anti-Federalists who were not so eager to give up the local autonomy won by the revolution: Antifederalists feared what Patrick Henry termed the "consolidated government" proposed by the new Constitution. They saw in Federalist hopes for commercial growth and international prestige only the lust of ambitious men for a "splendid empire" that, in the time-honored way of empires, would oppress the people with taxes, conscription, and military campaigns. Uncertain that any government over so vast a domain as the United States could be controlled by the people, Antifederalists saw in the enlarged powers of the general government only the familiar threats to the rights and liberties of the people. Historians have given many reasons for the perceived need to replace the articles in 1787. Jillson and Wilson (1994) point to the financial weakness as well as the norms, rules and institutional structures of the Congress, and the propensity to divide along sectional lines. Rakove (1988) identifies several factors that explain the collapse of the Confederation. The lack of compulsory direct taxation power was objectionable to those wanting a strong centralized state or expecting to benefit from such power. It could not collect customs after the war because tariffs were vetoed by Rhode Island. Rakove concludes that their failure to implement national measures "stemmed not from a heady sense of independence but rather from the enormous difficulties that all the states encountered in collecting taxes, mustering men, and gathering supplies from a war-weary populace." The second group of factors Rakove identified derived from the substantive nature of the problems the Continental Congress confronted after 1783, especially the inability to create a strong foreign policy. Finally, the Confederation's lack of coercive power reduced the likelihood for profit to be made by political means, thus potential rulers were uninspired to seek power. When the war ended in 1783, certain special interests had incentives to create a new "merchant state," much like the British state people had rebelled against. In particular, holders of war scrip and land speculators wanted a central government to pay off scrip at face value and to legalize western land holdings with disputed claims. Also, manufacturers wanted a high tariff as a barrier to foreign goods, but competition among states made this impossible without a central government. === Legitimacy of closing down === Political scientist David C. Hendrickson writes that two prominent political leaders in the Confederation, John Jay of New York and Thomas Burke of North Carolina believed that "the authority of the congress rested on the prior acts of the several states, to which the states gave their voluntary consent, and until those obligations were fulfilled, neither nullification of the authority of congress, exercising its due powers, nor secession from the compact itself was consistent with the terms of their original pledges."According to Article XIII of the Confederation, any alteration had to be approved unanimously: [T]he Articles of this Confederation shall be inviolably observed by every State, and the Union shall be perpetual; nor shall any alteration at any time hereafter be made in any of them; unless such alteration be agreed to in a Congress of the United States, and be afterwards confirmed by the legislatures of every State. On the other hand, Article VII of the proposed Constitution stated that it would become effective after ratification by a mere nine states, without unanimity: The Ratification of the Conventions of nine States, shall be sufficient for the Establishment of this Constitution between the States so ratifying the Same. The apparent tension between these two provisions was addressed at the time, and remains a topic of scholarly discussion. In 1788, James Madison remarked (in Federalist No. 40) that the issue had become moot: "As this objection...has been in a manner waived by those who have criticised the powers of the convention, I dismiss it without further observation." Nevertheless, it is an interesting historical and legal question whether opponents of the Constitution could have plausibly attacked the Constitution on that ground. At the time, there were state legislators who argued that the Constitution was not an alteration of the Articles of Confederation, but rather would be a complete replacement so the unanimity rule did not apply. Moreover, the Confederation had proven woefully inadequate and therefore was supposedly no longer binding.Modern scholars such as Francisco Forrest Martin agree that the Articles of Confederation had lost its binding force because many states had violated it, and thus "other states-parties did not have to comply with the Articles' unanimous consent rule". In contrast, law professor Akhil Amar suggests that there may not have really been any conflict between the Articles of Confederation and the Constitution on this point; Article VI of the Confederation specifically allowed side deals among states, and the Constitution could be viewed as a side deal until all states ratified it. === Final months === On July 3, 1788, the Congress received New Hampshire's all-important ninth ratification of the proposed Constitution, thus, according to its terms, establishing it as the new framework of governance for the ratifying states. The following day delegates considered a bill to admit Kentucky into the Union as a sovereign state. The discussion ended with Congress making the determination that, in light of this development, it would be "unadvisable" to admit Kentucky into the Union, as it could do so "under the Articles of Confederation" only, but not "under the Constitution".By the end of July 1788, 11 of the 13 states had ratified the new Constitution. Congress continued to convene under the Articles with a quorum until October. On Saturday, September 13, 1788, the Confederation Congress voted the resolve to implement the new Constitution, and on Monday, September 15 published an announcement that the new Constitution had been ratified by the necessary nine states, set the first Wednesday in February 1789 for the presidential electors to meet and select a new president, and set the first Wednesday of March 1789 as the day the new government would take over and the government under the Articles of Confederation would come to an end. On that same September 13, it determined that New York would remain the national capital. == See also == History of the United States (1776–1789) Perpetual Union Vetocracy Court of Appeals in Cases of Capture == References == == Further reading == Bernstein, R.B.

### Instruction: retrieve labels for this: The Atlantic Ocean is the second largest of the world's oceans, with an area of about 106,460,000 square kilometers (41,100,000 square miles). It covers approximately 20 percent of the Earth's surface and about 29 percent of its water surface area. It separates the "Old World" from the "New World". The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and the Americas to the west. As one component of the interconnected global ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Equatorial Counter Current subdivides it into the North Atlantic Ocean and the South Atlantic Ocean at about 8°N.Scientific explorations of the Atlantic include the Challenger expedition, the German Meteor expedition, Columbia University's Lamont-Doherty Earth Observatory and the United States Navy Hydrographic Office. == Etymology == The oldest known mentions of an "Atlantic" sea come from Stesichorus around mid-sixth century BC (Sch. A. R. 1. 211): Atlantikoi pelágei (Greek: Ἀτλαντικῷ πελάγει; English: 'the Atlantic sea'; etym. 'Sea of Atlantis') and in The Histories of Herodotus around 450 BC (Hdt. 1.202.4): Atlantis thalassa (Greek: Ἀτλαντὶς θάλασσα; English: 'Sea of Atlantis' or 'the Atlantis sea') where the name refers to "the sea beyond the pillars of Heracles" which is said to be part of the ocean that surrounds all land. Thus, on one hand, the name refers to Atlas, the Titan in Greek mythology, who supported the heavens and who later appeared as a frontispiece in Medieval maps and also lent his name to modern atlases. On the other hand, to early Greek sailors and in Ancient Greek mythological literature such as the Iliad and the Odyssey, this all-encompassing ocean was instead known as Oceanus, the gigantic river that encircled the world; in contrast to the enclosed seas well-known to the Greeks: the Mediterranean and the Black Sea. In contrast, the term "Atlantic" originally referred specifically to the Atlas Mountains in Morocco and the sea off the Strait of Gibraltar and the North African coast. The Greek word thalassa has been reused by scientists for the huge Panthalassa ocean that surrounded the supercontinent Pangaea hundreds of million years ago. The term "Aethiopian Ocean", derived from Ancient Ethiopia, was applied to the Southern Atlantic as late as the mid-19th century. During the Age of Discovery, the Atlantic was also known to English cartographers as the Great Western Ocean. == Extent and data == The International Hydrographic Organization (IHO) defined the limits of the oceans and seas in 1953, but some of these definitions have been revised since then and some are not used by various authorities, institutions, and countries, see for example the CIA World Factbook. Correspondingly, the extent and number of oceans and seas varies. The Atlantic Ocean is bounded on the west by North and South America. It connects to the Arctic Ocean through the Denmark Strait, Greenland Sea, Norwegian Sea and Barents Sea. To the east, the boundaries of the ocean proper are Europe: the Strait of Gibraltar (where it connects with the Mediterranean Sea–one of its marginal seas–and, in turn, the Black Sea, both of which also touch upon Asia) and Africa. In the southeast, the Atlantic merges into the Indian Ocean. The 20° East meridian, running south from Cape Agulhas to Antarctica defines its border. In the 1953 definition it extends south to Antarctica, while in later maps it is bounded at the 60° parallel by the Southern Ocean.The Atlantic has irregular coasts indented by numerous bays, gulfs and seas. These include the Baltic Sea, Black Sea, Caribbean Sea, Davis Strait, Denmark Strait, part of the Drake Passage, Gulf of Mexico, Labrador Sea, Mediterranean Sea, North Sea, Norwegian Sea, almost all of the Scotia Sea, and other tributary water bodies. Including these marginal seas the coast line of the Atlantic measures 111,866 km (69,510 mi) compared to 135,663 km (84,297 mi) for the Pacific.Including its marginal seas, the Atlantic covers an area of 106,460,000 km2 (41,100,000 sq mi) or 23.5% of the global ocean and has a volume of 310,410,900 km3 (74,471,500 cu mi) or 23.3% of the total volume of the earth's oceans. Excluding its marginal seas, the Atlantic covers 81,760,000 km2 (31,570,000 sq mi) and has a volume of 305,811,900 km3 (73,368,200 cu mi). The North Atlantic covers 41,490,000 km2 (16,020,000 sq mi) (11.5%) and the South Atlantic 40,270,000 km2 (15,550,000 sq mi) (11.1%). The average depth is 3,646 m (11,962 ft) and the maximum depth, the Milwaukee Deep in the Puerto Rico Trench, is 8,486 m (27,841 ft). == Bathymetry == The bathymetry of the Atlantic is dominated by a submarine mountain range called the Mid-Atlantic Ridge (MAR). It runs from 87°N or 300 km (190 mi) south of the North Pole to the subantarctic Bouvet Island at 42°S. === Mid-Atlantic Ridge === The MAR divides the Atlantic longitudinally into two halves, in each of which a series of basins are delimited by secondary, transverse ridges. The MAR reaches above 2,000 m (6,600 ft) along most of its length, but is interrupted by larger transform faults at two places: the Romanche Trench near the Equator and the Gibbs Fracture Zone at 53°N. The MAR is a barrier for bottom water, but at these two transform faults deep water currents can pass from one side to the other.The MAR rises 2–3 km (1.2–1.9 mi) above the surrounding ocean floor and its rift valley is the divergent boundary between the North American and Eurasian plates in the North Atlantic and the South American and African plates in the South Atlantic. The MAR produces basaltic volcanoes in Eyjafjallajökull, Iceland, and pillow lava on the ocean floor. The depth of water at the apex of the ridge is less than 2,700 m (1,500 fathoms; 8,900 ft) in most places, while the bottom of the ridge is three times as deep.The MAR is intersected by two perpendicular ridges: the Azores–Gibraltar Transform Fault, the boundary between the Nubian and Eurasian plates, intersects the MAR at the Azores Triple Junction, on either side of the Azores microplate, near the 40°N. A much vaguer, nameless boundary, between the North American and South American plates, intersects the MAR near or just north of the Fifteen-Twenty Fracture Zone, approximately at 16°N.In the 1870s, the Challenger expedition discovered parts of what is now known as the Mid-Atlantic Ridge, or: An elevated ridge rising to an average height of about 1,900 fathoms [3,500 m; 11,400 ft] below the surface traverses the basins of the North and South Atlantic in a meridianal direction from Cape Farewell, probably its far south at least as Gough Island, following roughly the outlines of the coasts of the Old and the New Worlds. The remainder of the ridge was discovered in the 1920s by the German Meteor expedition using echo-sounding equipment. The exploration of the MAR in the 1950s led to the general acceptance of seafloor spreading and plate tectonics.Most of the MAR runs under water but where it reaches the surfaces it has produced volcanic islands. While nine of these have collectively been nominated a World Heritage Site for their geological value, four of them are considered of "Outstanding Universal Value" based on their cultural and natural criteria: Þingvellir, Iceland; Landscape of the Pico Island Vineyard Culture, Portugal; Gough and Inaccessible Islands, United Kingdom; and Brazilian Atlantic Islands: Fernando de Noronha and Atol das Rocas Reserves, Brazil. === Ocean floor === Continental shelves in the Atlantic are wide off Newfoundland, southern-most South America, and north-eastern Europe. In the western Atlantic carbonate platforms dominate large areas, for example the Blake Plateau and Bermuda Rise. The Atlantic is surrounded by passive margins except at a few locations where active margins form deep trenches: the Puerto Rico Trench (8,414 m or 27,605 ft maximum depth) in the western Pacific and South Sandwich Trench (8,264 m or 27,113 ft) in the South Atlantic. There are numerous submarine canyons off north-eastern North America, western Europe, and north-western Africa. Some of these canyons extend along the continental rises and farther into the abyssal plains as deep-sea channels.In 1922 a historic moment in cartography and oceanography occurred. The USS Stewart used a Navy Sonic Depth Finder to draw a continuous map across the bed of the Atlantic. This involved little guesswork because the idea of sonar is straight forward with pulses being sent from the vessel, which bounce off the ocean floor, then return to the vessel. The deep ocean floor is thought to be fairly flat with occasional deeps, abyssal plains, trenches, seamounts, basins, plateaus, canyons, and some guyots. Various shelves along the margins of the continents constitute about 11% of the bottom topography with few deep channels cut across the continental rise. The mean depth between 60°N and 60°S is 3,730 m (12,240 ft), or close to the average for the global ocean, with a modal depth between 4,000 and 5,000 m (13,000 and 16,000 ft).In the South Atlantic the Walvis Ridge and Rio Grande Rise form barriers to ocean currents. The Laurentian Abyss is found off the eastern coast of Canada. == Water characteristics == Surface water temperatures, which vary with latitude, current systems, and season and reflect the latitudinal distribution of solar energy, range from below −2 °C (28 °F) to over 30 °C (86 °F). Maximum temperatures occur north of the equator, and minimum values are found in the polar regions. In the middle latitudes, the area of maximum temperature variations, values may vary by 7–8 °C (13–14 °F).From October to June the surface is usually covered with sea ice in the Labrador Sea, Denmark Strait, and Baltic Sea.The Coriolis effect circulates North Atlantic water in a clockwise direction, whereas South Atlantic water circulates counter-clockwise. The south tides in the Atlantic Ocean are semi-diurnal; that is, two high tides occur during each 24 lunar hours. In latitudes above 40° North some east-west oscillation, known as the North Atlantic oscillation, occurs. === Salinity === On average, the Atlantic is the saltiest major ocean; surface water salinity in the open ocean ranges from 33 to 37 parts per thousand (3.3 – 3.7%) by mass and varies with latitude and season. Evaporation, precipitation, river inflow and sea ice melting influence surface salinity values. Although the lowest salinity values are just north of the equator (because of heavy tropical rainfall), in general the lowest values are in the high latitudes and along coasts where large rivers enter. Maximum salinity values occur at about 25° north and south, in subtropical regions with low rainfall and high evaporation.The high surface salinity in the Atlantic, on which the Atlantic thermohaline circulation is dependent, is maintained by two processes: the Agulhas Leakage/Rings, which brings salty Indian Ocean waters into the South Atlantic, and the "Atmospheric Bridge", which evaporates subtropical Atlantic waters and exports it to the Pacific. === Water masses === The Atlantic Ocean consists of four major, upper water masses with distinct temperature and salinity. The Atlantic Subarctic Upper Water in the northern-most North Atlantic is the source for Subarctic Intermediate Water and North Atlantic Intermediate Water. North Atlantic Central Water can be divided into the Eastern and Western North Atlantic central Water since the western part is strongly affected by the Gulf Stream and therefore the upper layer is closer to underlying fresher subpolar intermediate water. The eastern water is saltier because of its proximity to Mediterranean Water. North Atlantic Central Water flows into South Atlantic Central Water at 15°N.There are five intermediate waters: four low-salinity waters formed at subpolar latitudes and one high-salinity formed through evaporation. Arctic Intermediate Water, flows from north to become the source for North Atlantic Deep Water south of the Greenland-Scotland sill. These two intermediate waters have different salinity in the western and eastern basins. The wide range of salinities in the North Atlantic is caused by the asymmetry of the northern subtropical gyre and the large number of contributions from a wide range of sources: Labrador Sea, Norwegian-Greenland Sea, Mediterranean, and South Atlantic Intermediate Water.The North Atlantic Deep Water (NADW) is a complex of four water masses, two that form by deep convection in the open ocean — Classical and Upper Labrador Sea Water — and two that form from the inflow of dense water across the Greenland-Iceland-Scotland sill — Denmark Strait and Iceland-Scotland Overflow Water. Along its path across Earth the composition of the NADW is affected by other water masses, especially Antarctic Bottom Water and Mediterranean Overflow Water. The NADW is fed by a flow of warm shallow water into the northern North Atlantic which is responsible for the anomalous warm climate in Europe. Changes in the formation of NADW have been linked to global climate changes in the past. Since man-made substances were introduced into the environment, the path of the NADW can be traced throughout its course by measuring tritium and radiocarbon from nuclear weapon tests in the 1960s and CFCs. === Gyres === The clockwise warm-water North Atlantic Gyre occupies the northern Atlantic, and the counter-clockwise warm-water South Atlantic Gyre appears in the southern Atlantic.In the North Atlantic, surface circulation is dominated by three inter-connected currents: the Gulf Stream which flows north-east from the North American coast at Cape Hatteras; the North Atlantic Current, a branch of the Gulf Stream which flows northward from the Grand Banks; and the Subpolar Front, an extension of the North Atlantic Current, a wide, vaguely defined region separating the subtropical gyre from the subpolar gyre. This system of currents transport warm water into the North Atlantic, without which temperatures in the North Atlantic and Europe would plunge dramatically. North of the North Atlantic Gyre, the cyclonic North Atlantic Subpolar Gyre plays a key role in climate variability. It is governed by ocean currents from marginal seas and regional topography, rather than being steered by wind, both in the deep ocean and at sea level. The subpolar gyre forms an important part of the global thermohaline circulation. Its eastern portion includes eddying branches of the North Atlantic Current which transport warm, saline waters from the subtropics to the north-eastern Atlantic. There this water is cooled during winter and forms return currents that merge along the eastern continental slope of Greenland where they form an intense (40–50 Sv) current which flows around the continental margins of the Labrador Sea. A third of this water become parts of the deep portion of the North Atlantic Deep Water (NADW). The NADW, in its turn, feed the meridional overturning circulation (MOC), the northward heat transport of which is threatened by anthropogenic climate change. Large variations in the subpolar gyre on a decade-century scale, associated with the North Atlantic oscillation, are especially pronounced in Labrador Sea Water, the upper layers of the MOC.The South Atlantic is dominated by the anti-cyclonic southern subtropical gyre. The South Atlantic Central Water originates in this gyre, while Antarctic Intermediate Water originates in the upper layers of the circumpolar region, near the Drake Passage and Falkland Islands. Both these currents receive some contribution from the Indian Ocean. On the African east coast the small cyclonic Angola Gyre lies embedded in the large subtropical gyre. The southern subtropical gyre is partly masked by a wind-induced Ekman layer. The residence time of the gyre is 4.4–8.5 years. North Atlantic Deep Water flows southerward below the thermocline of the subtropical gyre. === Sargasso Sea === The Sargasso Sea in the western North Atlantic can be defined as the area where two species of Sargassum (S. fluitans and natans) float, an area 4,000 km (2,500 mi) wide and encircled by the Gulf Stream, North Atlantic Drift, and North Equatorial Current. This population of seaweed probably originated from Tertiary ancestors on the European shores of the former Tethys Ocean and has, if so, maintained itself by vegetative growth, floating in the ocean for millions of years. Other species endemic to the Sargasso Sea include the sargassum fish, a predator with algae-like appendages who hovers motionless among the Sargassum. Fossils of similar fishes have been found in fossil bays of the former Tethys Ocean, in what is now the Carpathian region, that were similar to the Sargasso Sea. It is possible that the population in the Sargasso Sea migrated to the Atlantic as the Tethys closed at the end of the Miocene around 17 Ma. The origin of the Sargasso fauna and flora remained enigmatic for centuries. The fossils found in the Carpathians in the mid-20th century, often called the "quasi-Sargasso assemblage", finally showed that this assemblage originated in the Carpathian Basin from were it migrated over Sicily to the Central Atlantic where it evolved into modern species of the Sargasso Sea.The location of the spawning ground for European eels remained unknown for decades. In the early 19th century it was discovered that the southern Sargasso Sea is the spawning ground for both the European and American eel and that the former migrate more than 5,000 km (3,100 mi) and the latter 2,000 km (1,200 mi). Ocean currents such as the Gulf Stream transport eel larvae from the Sargasso Sea to foraging areas in North America, Europe, and Northern Africa. Recent but disputed research suggests that eels possibly use Earth's magnetic field to navigate through the ocean both as larvae and as adults. == Climate == Climate is influenced by the temperatures of the surface waters and water currents as well as winds. Because of the ocean's great capacity to store and release heat, maritime climates are more moderate and have less extreme seasonal variations than inland climates. Precipitation can be approximated from coastal weather data and air temperature from water temperatures.The oceans are the major source of the atmospheric moisture that is obtained through evaporation. Climatic zones vary with latitude; the warmest zones stretch across the Atlantic north of the equator. The coldest zones are in high latitudes, with the coldest regions corresponding to the areas covered by sea ice. Ocean currents influence climate by transporting warm and cold waters to other regions. The winds that are cooled or warmed when blowing over these currents influence adjacent land areas.The Gulf Stream and its northern extension towards Europe, the North Atlantic Drift is thought to have at least some influence on climate. For example, the Gulf Stream helps moderate winter temperatures along the coastline of southeastern North America, keeping it warmer in winter along the coast than inland areas. The Gulf Stream also keeps extreme temperatures from occurring on the Florida Peninsula. In the higher latitudes, the North Atlantic Drift, warms the atmosphere over the oceans, keeping the British Isles and north-western Europe mild and cloudy, and not severely cold in winter like other locations at the same high latitude. The cold water currents contribute to heavy fog off the coast of eastern Canada (the Grand Banks of Newfoundland area) and Africa's north-western coast. In general, winds transport moisture and air over land areas. === Natural hazards === Icebergs are common from early February to the end of July across the shipping lanes near the Grand Banks of Newfoundland. The ice season is longer in the polar regions, but there is little shipping in those areas.Hurricanes are hazard in the western parts of the North Atlantic during the summer and autumn. Due to a consistently strong wind shear and a weak Intertropical Convergence Zone, they are practically unknown in the South Atlantic. == Plate tectonics == === Central Atlantic === The break-up of Pangaea began in the Central Atlantic, between North America and Northwest Africa, where rift basins opened during the Late Triassic and Early Jurassic. This period also saw the first stages of the uplift of the Atlas Mountains. The exact timing is controversial with estimates ranging from 200 to 170 Ma.The opening of the Atlantic Ocean coincided with the initial break-up of the supercontinent Pangaea, both of which were initiated by the eruption of the Central Atlantic Magmatic Province (CAMP), one of the most extensive and voluminous large igneous provinces in Earth's history associated with the Triassic–Jurassic extinction event, one of Earth's major extinction events. Theoliitic dikes, sills, and lava flows from the CAMP eruption at 200 Ma have been found in West Africa, eastern North America, and northern South America. The extent of the volcanism has been estimated to 4.5×106 km2 (1.7×106 sq mi) of which 2.5×106 km2 (9.7×105 sq mi) covered what is now northern and central Brazil.The formation of the Central American Isthmus closed the Central American Seaway at the end of the Pliocene 2.8 Ma ago. The formation of the isthmus resulted in the migration and extinction of many land-living animals, known as the Great American Interchange, but the closure of the seaway resulted in a "Great American Schism" as it affected ocean currents, salinity, and temperatures in both the Atlantic and Pacific. Marine organisms on both sides of the isthmus became isolated and either diverged or went extinct. === Northern Atlantic === Geologically the Northern Atlantic is the area delimited to the south by two conjugate margins, Newfoundland and Iberia, and to the north by the Arctic Eurasian Basin. The opening of the Northern Atlantic closely followed the margins of its predecessor, the Iapetus Ocean, and spread from the Central Atlantic in six stages: Iberia–Newfoundland, Porcupine–North America, Eurasia–Greenland, Eurasia–North America. Active and inactive spreading systems in this area are marked by the interaction with the Iceland hotspot. === South Atlantic === West Gondwana (South America and Africa) broke up in the Early Cretaceous to form the South Atlantic. The apparent fit between the coastlines of the two continents was noted on the first maps that included the South Atlantic and it was also the subject of the first computer-assisted plate tectonic reconstructions in 1965. This magnificent fit, however, has since then proven problematic and later reconstructions have introduced various deformation zones along the shorelines to accommodate the northward-propagating break-up. Intra-continental rifts and deformations have also been introduced to subdivide both continental plates into sub-plates.Geologically the South Atlantic can be divided into four segments: Equatorial segment, from 10°N to the Romanche Fracture Zone (RFZ);; Central segment, from RFZ to Florianopolis Fracture Zone (FFZ, north of Walvis Ridge and Rio Grande Rise); Southern segment, from FFZ to the Agulhas-Falkland Fracture Zone (AFFZ); and Falkland segment, south of AFFZ.In the southern segment the Early Cretaceous (133–130 Ma) intensive magmatism of the Paraná–Etendeka Large Igneous Province produced by the Tristan hotspot resulted in an estimated volume of 1.5×106 to 2.0×106 km3 (3.6×105 to 4.8×105 cu mi). It covered an area of 1.2×106 to 1.6×106 km2 (4.6×105 to 6.2×105 sq mi) in Brazil, Paraguay, and Uruguay and 0.8×105 km2 (3.1×104 sq mi) in Africa. Dyke swarms in Brazil, Angola, eastern Paraguay, and Namibia, however, suggest the LIP originally covered a much larger area and also indicate failed rifts in all these areas. Associated offshore basaltic flows reach as far south as the Falkland Islands and South Africa. Traces of magmatism in both offshore and onshore basins in the central and southern segments have been dated to 147–49 Ma with two peaks between 143–121 Ma and 90–60 Ma.In the Falkland segment rifting began with dextral movements between the Patagonia and Colorado sub-plates between the Early Jurassic (190 Ma) and the Early Cretaceous (126.7 Ma). Around 150 Ma sea-floor spreading propagated northward into the southern segment. No later than 130 Ma rifting had reached the Walvis Ridge–Rio Grande Rise.In the central segment rifting started to break Africa in two by opening the Benue Trough around 118 Ma. Rifting in the central segment, however, coincided with the Cretaceous Normal Superchron (also known as the Cretaceous quiet period), a 40 Ma period without magnetic reversals, which makes it difficult to date sea-floor spreading in this segment.The equatorial segment is the last phase of the break-up, but, because it is located on the Equator, magnetic anomalies cannot be used for dating. Various estimates date the propagation of sea-floor spreading in this segment to the period 120–96 Ma. This final stage, nevertheless, coincided with or resulted in the end of continental extension in Africa.About 50 Ma the opening of the Drake Passage resulted from a change in the motions and separation rate of the South American and Antarctic plates. First small ocean basins opened and a shallow gateway appeared during the Middle Eocene. 34–30 Ma a deeper seaway developed, followed by an Eocene–Oligocene climatic deterioration and the growth of the Antarctic ice sheet. === Closure of the Atlantic === An embryonic subduction margin is potentially developing west of Gibraltar. The Gibraltar Arc in the western Mediterranean is migrating westward into the Central Atlantic where it joins the converging African and Eurasian plates. Together these three tectonic forces are slowly developing into a new subduction system in the eastern Atlantic Basin. Meanwhile, the Scotia Arc and Caribbean Plate in the western Atlantic Basin are eastward-propagating subduction systems that might, together with the Gibraltar system, represent the beginning of the closure of the Atlantic Ocean and the final stage of the Atlantic Wilson cycle. == History == === Human origin === Humans evolved in Africa; first by diverging from other apes around 7 Ma; then developing stone tools around 2.6 Ma; to finally evolve as modern humans around 100 kya. The earliest evidences for the complex behavior associated with this behavioral modernity has been found in the Greater Cape Floristic Region (GCFR) along the coast of South Africa. During the latest glacial stages the now-submerged plains of the Agulhas Bank were exposed above sea level, extending the South African coastline farther south by hundreds of kilometers. A small population of modern humans — probably fewer than a thousand reproducing individuals — survived glacial maxima by exploring the high diversity offered by these Palaeo-Agulhas plains. The GCFR is delimited to the north by the Cape Fold Belt and the limited space south of it resulted in the development of social networks out of which complex Stone Age technologies emerged. Human history thus begins on the coasts of South Africa where the Atlantic Benguela Upwelling and Indian Ocean Agulhas Current meet to produce an intertidal zone on which shellfish, fur seal, fishes and sea birds provided the necessary protein sources. The African origin of this modern behaviour is evidenced by 70,000 years-old engravings from Blombos Cave, South Africa. === Old World === Mitochondrial DNA (mtDNA) studies indicate that 80–60,000 years ago a major demographic expansion within Africa, derived from a single, small population, coincided with the emergence of behavioral complexity and the rapid MIS 5–4 environmental changes. This group of people not only expanded over the whole of Africa, but also started to disperse out of Africa into Asia, Europe, and Australasia around 65,000 years ago and quickly replaced the archaic humans in these regions. During the Last Glacial Maximum (LGM) 20,000 years ago humans had to abandon their initial settlements along the European North Atlantic coast and retreat to the Mediterranean. Following rapid climate changes at the end of the LGM this region was repopulated by Magdalenian culture. Other hunter-gatherers followed in waves interrupted by large-scale hazards such as the Laacher See volcanic eruption, the inundation of Doggerland (now the North Sea), and the formation of the Baltic Sea. The European coasts of the North Atlantic were permanently populated about 9–8.5 thousand years ago.This human dispersal left abundant traces along the coasts of the Atlantic Ocean. 50 ka-old, deeply stratified shell middens found in Ysterfontein on the western coast of South Africa are associated with the Middle Stone Age (MSA). The MSA population was small and dispersed and the rate of their reproduction and exploitation was less intense than those of later generations. While their middens resemble 12–11 ka-old Late Stone Age (LSA) middens found on every inhabited continent, the 50–45 ka-old Enkapune Ya Muto in Kenya probably represents the oldest traces of the first modern humans to disperse out of Africa. The same development can be seen in Europe. In La Riera Cave (23–13 ka) in Asturias, Spain, only some 26,600 molluscs were deposited over 10 ka. In contrast, 8–7 ka-old shell middens in Portugal, Denmark, and Brazil generated thousands of tons of debris and artefacts. The Ertebølle middens in Denmark, for example, accumulated 2,000 m3 (71,000 cu ft) of shell deposits representing some 50 million molluscs over only a thousand years. This intensification in the exploitation of marine resources has been described as accompanied by new technologies — such as boats, harpoons, and fish-hooks — because many caves found in the Mediterranean and on the European Atlantic coast have increased quantities of marine shells in their upper levels and reduced quantities in their lower. The earliest exploitation, however, took place on the now submerged shelves, and most settlements now excavated were then located several kilometers from these shelves. The reduced quantities of shells in the lower levels can represent the few shells that were exported inland. === New World === During the LGM the Laurentide Ice Sheet covered most of northern North America while Beringia connected Siberia to Alaska. In 1973 late American geoscientist Paul S. Martin proposed a "blitzkrieg" colonization of the Americas by which Clovis hunters migrated into North America around 13,000 years ago in a single wave through an ice-free corridor in the ice sheet and "spread southward explosively, briefly attaining a density sufficiently large to overkill much of their prey." Others later proposed a "three-wave" migration over the Bering Land Bridge. These hypotheses remained the long-held view regarding the settlement of the Americas, a view challenged by more recent archaeological discoveries: the oldest archaeological sites in the Americas have been found in South America; sites in north-east Siberia report virtually no human presence there during the LGM; and most Clovis artefacts have been found in eastern North America along the Atlantic coast. Furthermore, colonisation models based on mtDNA, yDNA, and atDNA data respectively support neither the "blitzkrieg" nor the "three-wave" hypotheses but they also deliver mutually ambiguous results. Contradictory data from archaeology and genetics will most likely deliver future hypotheses that will, eventually, confirm each other. A proposed route across the Pacific to South America could explain early South American finds and another hypothesis proposes a northern path, through the Canadian Arctic and down the North American Atlantic coast. Early settlements across the Atlantic have been suggested by alternative theories, ranging from purely hypothetical to mostly disputed, including the Solutrean hypothesis and some of the Pre-Columbian trans-oceanic contact theories. The Norse settlement of the Faroe Islands and Iceland began during the 9th and 10th centuries. A settlement on Greenland was established before 1000 CE, but contact with it was lost in 1409 and it was finally abandoned during the early Little Ice Age. This setback was caused by a range of factors: an unsustainable economy resulted in erosion and denudation, while conflicts with the local Inuit resulted in the failure to adapt their Arctic technologies; a colder climate resulted in starvation; and the colony got economically marginalized as the Great Plague and Barbary pirates harvested its victims on Iceland in the 15th century. Iceland was initially settled 865–930 CE following a warm period when winter temperatures hovered around 2 °C (36 °F) which made farming favorable at high latitudes. This did not last, however, and temperatures quickly dropped; at 1080 CE summer temperatures had reached a maximum of 5 °C (41 °F). The Landnámabók (Book of Settlement) records disastrous famines during the first century of settlement — "men ate foxes and ravens" and "the old and helpless were killed and thrown over cliffs" — and by the early 1200s hay had to be abandoned for short-season crops such as barley. === Atlantic World === Christopher Columbus discovered the Americas in 1492 under Spanish flag. Six years later Vasco da Gama reached India under Portuguese flag, by navigating south around the Cape of Good Hope, thus proving that the Atlantic and Indian Oceans are connected. In 1500, in his voyage to India following Vasco da Gama, Pedro Alvares Cabral reached Brazil, taken by the currents of the South Atlantic Gyre. Following these explorations, Spain and Portugal quickly conquered and colonized large territories in the New World and forced the Amerindian population into slavery in order to explore the vast quantities of silver and gold they found. Spain and Portugal monopolized this trade in order to keep other European nations out, but conflicting interests nevertheless led to a series of Spanish-Portuguese wars. A peace treaty mediated by the Pope divided the conquered territories into Spanish and Portuguese sectors while keeping other colonial powers away. England, France, and the Dutch Republic enviously watched the Spanish and Portuguese wealth grow and allied themselves with pirates such as Henry Mainwaring and Alexandre Exquemelin. They could explore the convoys leaving the Americas because prevailing winds and currents made the transport of heavy metals slow and predictable. In the colonies of the Americas, depredation, disease, and slavery quickly reduced the indigenous population of the Americas to the extent that the Atlantic slave trade had to be introduced to replace them — a trade that became norm and an integral part of the colonization. Between the 15th century and 1888, when Brazil became the last part of the Americas to end slave trade, an estimated ten million Africans were exported as slaves, most of them destined for agricultural labour. The slave trade was officially abolished in the British Empire and the United States in 1808, and slavery itself was abolished in the British Empire in 1838 and in the United States in 1865 after the Civil War.From Columbus to the Industrial Revolution Trans-Atlantic trade, including colonialism and slavery, became crucial for Western Europe. For European countries with a direct access to the Atlantic (including Britain, France, the Netherlands, Portugal, and Spain) 1500–1800 was a period of sustained growth during which these countries grew richer than those in Eastern Europe and Asia. Colonialism evolved as part of the Trans-Atlantic trade, but this trade also strengthened the position of merchant groups at the expense of monarchs. Growth was more rapid in non-absolutist countries, such as Britain and the Netherlands, and more limited in absolutist monarchies, such as Portugal, Spain, and France, where profit mostly or exclusively benefited the monarchy and its allies.Trans-Atlantic trade also resulted in an increasing urbanization: in European countries facing the Atlantic urbanization grew from 8% in 1300, 10.1% in 1500, to 24.5% in 1850; in other European countries from 10% in 1300, 11.4% in 1500, to 17% in 1850. Likewise, GDP doubled in Atlantic countries but rose by only 30% in the rest of Europe. By end of the 17th century the volume of the Trans-Atlantic trade had surpassed that of the Mediterranean trade. == Economy == The Atlantic has contributed significantly to the development and economy of surrounding countries. Besides major transatlantic transportation and communication routes, the Atlantic offers abundant petroleum deposits in the sedimentary rocks of the continental shelves.The Atlantic harbors petroleum and gas fields, fish, marine mammals (seals and whales), sand and gravel aggregates, placer deposits, polymetallic nodules, and precious stones. Gold deposits are a mile or two under water on the ocean floor, however the deposits are also encased in rock that must be mined through. Currently, there is no cost-effective way to mine or extract gold from the ocean to make a profit.Various international treaties attempt to reduce pollution caused by environmental threats such as oil spills, marine debris, and the incineration of toxic wastes at sea. === Fisheries === The shelves of the Atlantic hosts one of the world's richest fishing resources. The most productive areas include the Grand Banks of Newfoundland, the Scotian Shelf, Georges Bank off Cape Cod, the Bahama Banks, the waters around Iceland, the Irish Sea, the Bay of Fundy, the Dogger Bank of the North Sea, and the Falkland Banks. Fisheries have, however, undergone significant changes since the 1950s and global catches can now be divided into three groups of which only two are observed in the Atlantic: fisheries in the Eastern Central and South-West Atlantic oscillate around a globally stable value, the rest of the Atlantic is in overall decline following historical peaks. The third group, "continuously increasing trend since 1950", is only found in the Indian Ocean and Western Pacific. In the North-East Atlantic total catches decreased between the mid-1970s and the 1990s and reached 8.7 million tons in 2013. Blue whiting reached a 2.4 million tons peak in 2004 but was down to 628,000 tons in 2013. Recovery plans for cod, sole, and plaice have reduced mortality in these species. Arctic cod reached its lowest levels in the 1960s–1980s but is now recovered. Arctic saithe and haddock are considered fully fished; Sand eel is overfished as was capelin which has now recovered to fully fished. Limited data makes the state of redfishes and deep-water species difficult to assess but most likely they remain vulnerable to overfishing. Stocks of northern shrimp and Norwegian lobster are in good condition. In the North-East Atlantic 21% of stocks are considered overfished. In the North-West Atlantic landings have decreased from 4.2 million tons in the early 1970s to 1.9 million tons in 2013. During the 21st century some species have shown weak signs of recovery, including Greenland halibut, yellowtail flounder, Atlantic halibut, haddock, spiny dogfish, while other stocks shown no such signs, including cod, witch flounder, and redfish. Stocks of invertebrates, in contrast, remain at record levels of abundance. 31% of stocks are overfished in the North-west Atlantic. In 1497 John Cabot became the first to explore mainland North America and one of his major discoveries was the abundant resources of Atlantic cod off Newfoundland. Referred to as "Newfoundland Currency" this discovery yielded some 200 million tons of fish over five centuries. In the late 19th and early 20th centuries new fisheries started to exploit haddock, mackerel, and lobster. From the 1950s to the 1970s the introduction of European and Asian distant-water fleets in the area dramatically increased the fishing capacity and number of exploited species. It also expanded the exploited areas from near-shore to the open sea and to great depths to include deep-water species such as redfish, Greenland halibut, witch flounder, and grenadiers. Overfishing in the area was recognised as early as the 1960s but, because this was occurring on international waters, it took until the late 1970s before any attempts to regulate was made. In the early 1990s this finally resulted in the collapse of the Atlantic northwest cod fishery. The population of a number of deep-sea fishes also collapsed in the process, including American plaice, redfish, and Greenland halibut, together with flounder and grenadier.In the Eastern Central Atlantic small pelagic fishes constitute about 50% of landings with sardine reaching 0.6–1.0 million tons per year. Pelagic fish stocks are considered fully fishes or overfished, with sardines south of Cape Bojador the notable exception. Almost half of stocks are fished at biologically unsustainable levels. Total catches have been fluctuating since the 1970s; reaching 3.9 million tons in 2013 or slightly less than the peak production in 2010. In the Western Central Atlantic catches have been decreasing since 2000 and reached 1.3 million tons in 2013. The most important species in the area, Gulf menhaden, reached a million tons in the mid-1980s but only half a million tons in 2013 and is now considered fully fished. Round sardinella was an important species in the 1990s but is now considered overfished. Groupers and snappers are overfished and northern brown shrimp and American cupped oyster are considered fully fished approaching overfished. 44% of stocks are being fished at unsustainable levels. In the South-East Atlantic catches have decreased from 3.3 million tons in the early 1970s to 1.3 million tons in 2013. Horse mackerel and hake are the most important species, together representing almost half of the landings. Off South Africa and Namibia deep-water hake and shallow-water Cape hake have recovered to sustainable levels since regulations were introduced in 2006 and the states of Southern African pilchard and anchovy have improved to fully fished in 2013.In the South-West Atlantic a peak was reached in the mid-1980s and catches now fluctuate between 1.7 and 2.6 million tons. The most important species, the Argentine shortfin squid, which reached half a million tons in 2013 or half the peak value, is considered fully fished to overfished. Another important species was the Brazilian sardinella, with a production of 100,000 tons in 2013 it is now considered overfished. Half the stocks in this area are being fished at unsustainable levels: Whitehead’s round herring has not yet reached fully fished but Cunene horse mackerel is overfished. The sea snail perlemoen abalone is targeted by illegal fishing and remain overfished. == Environmental issues == Endangered marine species include the manatee, seals, sea lions, turtles, and whales. Drift net fishing can kill dolphins, albatrosses and other seabirds (petrels, auks), hastening the fish stock decline and contributing to international disputes. Municipal pollution comes from the eastern United States, southern Brazil, and eastern Argentina; oil pollution in the Caribbean Sea, Gulf of Mexico, Lake Maracaibo, Mediterranean Sea, and North Sea; and industrial waste and municipal sewage pollution in the Baltic Sea, North Sea, and Mediterranean Sea. North Atlantic hurricane activity has increased over past decades because of increased sea surface temperature (SST) at tropical latitudes, changes that can be attributed to either the natural Atlantic Multidecadal Oscillation (AMO) or to anthropogenic climate change. A 2005 report indicated that the Atlantic meridional overturning circulation (AMOC) slowed down by 30% between 1957 and 2004. If the AMO were responsible for SST variability, the AMOC would have increased in strength, which is apparently not the case. Furthermore, it is clear from statistical analyses of annual tropical cyclones that these changes do not display multidecadal cyclicity. Therefore, these changes in SST must be caused by human activities.The ocean mixed layer plays an important role heat storage over seasonal and decadal time-scales, whereas deeper layers are affected over millennia and has a heat capacity about 50 times that of the mixed layer. This heat uptake provides a time-lag for climate change but it also results in a thermal expansion of the oceans which contribute to sea-level rise. 21st century global warming will probably result in an equilibrium sea-level rise five times greater than today, whilst melting of glaciers, including that of the Greenland ice-sheet, expected to have virtually no effect during the 21st century, will probably result in a sea-level rise of 3–6 m over a millennium.On 7 June 2006, Florida's wildlife commission voted to take the manatee off the state's endangered species list. Some environmentalists worry that this could erode safeguards for the popular sea creature. Marine pollution is a generic term for the entry into the ocean of potentially hazardous chemicals or particles. The biggest culprits are rivers and with them many agriculture fertilizer chemicals as well as livestock and human waste. The excess of oxygen-depleting chemicals leads to hypoxia and the creation of a dead zone.Marine debris, which is also known as marine litter, describes human-created waste floating in a body of water. Oceanic debris tends to accumulate at the center of gyres and coastlines, frequently washing aground where it is known as beach litter. == See also == List of countries and territories bordering the Atlantic Ocean Seven Seas Gulf Stream shutdown Shipwrecks in the Atlantic Ocean Atlantic hurricanes Transatlantic crossing == References == === Notes === === Sources === == Further reading == Winchester, Simon (2010).

### Instruction: retrieve labels for this: Angola (; Portuguese: [ɐ̃ˈɡɔlɐ]), officially the Republic of Angola (Portuguese: República de Angola; Kikongo, Kimbundu and Umbundu: Repubilika ya Ngola), is a country in Southern Africa. It is the seventh-largest country in Africa, bordered by Namibia to the south, the Democratic Republic of the Congo to the north, Zambia to the east, and the Atlantic Ocean to the west. The exclave province of Cabinda borders the Republic of the Congo and the Democratic Republic of the Congo. The capital and largest city of Angola is Luanda. Although inhabited since the Paleolithic Era, what is now Angola was molded by Portuguese colonisation. It began with, and was for centuries limited to, coastal settlements and trading posts established starting in the 16th century. In the 19th century, European settlers slowly and hesitantly began to establish themselves in the interior. The Portuguese colony that became Angola did not have its present borders until the early 20th century because of resistance by groups such as the Cuamato, the Kwanyama and the Mbunda. After a protracted anti-colonial struggle, independence was achieved in 1975 as the Marxist-Leninist People's Republic of Angola, a one-party state supported by the Soviet Union and Cuba. The civil war between the ruling People's Movement for the Liberation of Angola (MPLA) and the insurgent anti-communist National Union for the Total Independence of Angola (UNITA), supported by the United States and apartheid South Africa, lasted until 2002. It has since become a relatively stable unitary presidential republic. Angola has vast mineral and petroleum reserves, and its economy is among the fastest-growing in the world, especially since the end of the civil war; however the standard of living remains low for most of the population, and life expectancy in Angola is among the lowest in the world, while infant mortality is among the highest. Angola's economic growth is highly uneven, with most of the nation's wealth concentrated in a disproportionately small sector of the population.Angola is a member state of the United Nations, OPEC, African Union, the Community of Portuguese Language Countries, and the Southern African Development Community. A highly multiethnic country, Angola's 25.8 million people span tribal groups, customs, and traditions. Angolan culture reflects centuries of Portuguese rule, in the predominance of the Portuguese language and of the Catholic Church. == Etymology == The name Angola comes from the Portuguese colonial name Reino de Angola (Kingdom of Angola), which appeared as early as Dias de Novais's 1571 charter. The toponym was derived by the Portuguese from the title ngola held by the kings of Ndongo. Ndongo in the highlands, between the Kwanza and Lukala Rivers, was nominally a possession of the Kingdom of Kongo, but was seeking greater independence in the 16th century. == History == === Early migrations and political units === Modern Angola was populated predominantly by nomadic Khoi and San prior to the first Bantu migrations. The Khoi and San peoples were neither pastoralists nor cultivators, but hunter-gatherers. They were displaced by Bantu peoples arriving from the north, most of whom likely originated in what is today northwestern Nigeria and southern Niger. Bantu speakers introduced the cultivation of bananas and taro, as well as large cattle herds, to Angola's central highlands and the Luanda plain. To its south lay the Kingdom of Ndongo, from which the area of the later Portuguese colony was sometimes known as Dongo. === Portuguese colonisation === Portuguese explorer Diogo Cão reached the area in 1484. The previous year, the Portuguese had established relations with the Kongo, which stretched at the time from modern Gabon in the north to the Kwanza River in the south. The Portuguese established their primary early trading post at Soyo, which is now the northernmost city in Angola apart from the Cabinda exclave. Paulo Dias de Novais founded São Paulo de Loanda (Luanda) in 1575 with a hundred families of settlers and four hundred soldiers. Benguela was fortified in 1587 and became a township in 1617. The Portuguese established several other settlements, forts and trading posts along the Angolan coast, principally trading in Angolan slaves for Brazilian plantations. Local slave dealers provided a large number of slaves for the Portuguese Empire, usually in exchange for manufactured goods from Europe.This part of the Atlantic slave trade continued until after Brazil's independence in the 1820s.Despite Portugal's territorial claims in Angola, its control over much of the country's vast interior was minimal. In the 16th century Portugal gained control of the coast through a series of treaties and wars. Life for European colonists was difficult and progress slow. John Iliffe notes that "Portuguese records of Angola from the 16th century show that a great famine occurred on average every seventy years; accompanied by epidemic disease, it might kill one-third or one-half of the population, destroying the demographic growth of a generation and forcing colonists back into the river valleys". During the Portuguese Restoration War, the Dutch West India Company occupied the principal settlement of Luanda in 1641, using alliances with local peoples to carry out attacks against Portuguese holdings elsewhere. A fleet under Salvador de Sá retook Luanda in 1648; reconquest of the rest of the territory was completed by 1650. New treaties with the Kongo were signed in 1649; others with Njinga's Kingdom of Matamba and Ndongo followed in 1656. The conquest of Pungo Andongo in 1671 was the last major Portuguese expansion from Luanda, as attempts to invade Kongo in 1670 and Matamba in 1681 failed. Colonial outposts also expanded inward from Benguela, but until the late 19th century the inroads from Luanda and Benguela were very limited. Hamstrung by a series of political upheavals in the early 1800s, Portugal was slow to mount a large scale annexation of Angolan territory.The slave trade was abolished in Angola in 1836, and in 1854 the colonial government freed all its existing slaves. Four years later, a more progressive administration appointed by Lisbon abolished slavery altogether. However, these decrees remained largely unenforceable, and the Portuguese depended on assistance from the British Royal Navy to enforce their ban on the slave trade. This coincided with a series of renewed military expeditions into the hinterland. By the mid-nineteenth century Portugal had established its dominion as far east as the Congo River and as far south as Mossâmedes. Until the late 1880s, Lisbon entertained proposals to link Angola with its colony in Mozambique but was blocked by British and Belgian opposition. In this period, the Portuguese came up against different forms of armed resistance from various peoples in Angola.The Berlin Conference in 1884–1885 set the colony's borders, delineating the boundaries of Portuguese claims in Angola, although many details were unresolved until the 1920s. Trade between Portugal and her African territories also rapidly increased as a result of protective tariffs, leading to increased development, and a wave of new Portuguese immigrants. === Rise of Angolan nationalism === Under colonial law, black Angolans were forbidden from forming political parties or labour unions. The first nationalist movements did not take root until after World War II, spearheaded by a largely Westernised, Portuguese-speaking urban class which included many mestiços. During the early 1960s they were joined by other associations stemming from ad hoc labour activism in the rural workforce. Portugal's refusal to address increasing Angolan demands for self-determination provoked an armed conflict which erupted in 1961 with the Baixa de Cassanje revolt and gradually evolved into a protracted war of independence that persisted for the next twelve years. Throughout the conflict, three militant nationalist movements with their own partisan guerrilla wings emerged from the fighting between the Portuguese government and local forces, supported to varying degrees by the Portuguese Communist Party.The National Front for the Liberation of Angola (FNLA) recruited from Bakongo refugees in Zaire. Benefiting from particularly favourable political circumstances in Léopoldville, and especially from a common border with Zaire, Angolan political exiles were able to build up a power base among a large expatriate community from related families, clans, and traditions. People on both sides of the border spoke mutually intelligible dialects and enjoyed shared ties to the historical Kingdom of Kongo. Though as foreigners skilled Angolans could not take advantage of Mobutu Sese Seko's state employment programme, some found work as middlemen for the absentee owners of various lucrative private ventures. The migrants eventually formed the FNLA with the intention of making a bid for political power upon their envisaged return to Angola.A largely Ovimbundu guerrilla initiative against the Portuguese in central Angola from 1966 was spearheaded by Jonas Savimbi and the National Union for the Total Independence of Angola (UNITA). It remained handicapped by its geographic remoteness from friendly borders, the ethnic fragmentation of the Ovimbundu, and the isolation of peasants on European plantations where they had little opportunity to mobilise. During the late 1950s, the rise of the Marxist–Leninist Popular Movement for the Liberation of Angola (MPLA) in the east and Dembos hills north of Luanda came to hold special significance. Formed as a coalition resistance movement by the Angolan Communist Party, the organisation's leadership remained predominantly Ambundu and courted public sector workers in Luanda. Although both the MPLA and its rivals accepted material assistance from the Soviet Union or the People's Republic of China, the former harboured strong anti-imperialist views and was openly critical of the United States and its support for Portugal. This allowed it to win important ground on the diplomatic front, soliciting support from nonaligned governments in Morocco, Ghana, Guinea, Mali, and the United Arab Republic.The MPLA attempted to move its headquarters from Conakry to Léopoldville in October 1961, renewing efforts to create a common front with the FNLA, then known as the Union of Angolan Peoples (UPA) and its leader Holden Roberto. Roberto turned down the offer. When the MPLA first attempted to insert its own insurgents into Angola, the cadres were ambushed and annihilated by UPA partisans on Roberto's orders—setting a precedent for the bitter factional strife which would later ignite the Angolan Civil War. === Civil war === Throughout the war of independence, the three rival nationalist movements were severely hampered by political and military factionalism, as well as their inability to unite guerrilla efforts against the Portuguese. Between 1961 and 1975 the MPLA, UNITA, and the FNLA competed for influence in the Angolan population and the international community. The Soviet Union and Cuba became especially sympathetic towards the MPLA and supplied that party with arms, ammunition, funding, and training. They also backed UNITA militants until it became clear that the latter was at irreconcilable odds with the MPLA.The collapse of Portugal's Estado Novo government following the 1974 Carnation Revolution suspended all Portuguese military activity in Africa and the brokering of a ceasefire pending negotiations for Angolan independence. Encouraged by the Organisation of African Unity, Holden Roberto, Jonas Savimbi, and MPLA chairman Agostinho Neto met in Mombasa in early January 1975 and agreed to form a coalition government. This was ratified by the Alvor Agreement later that month, which called for general elections and set the country's independence date for 11 November 1975. All three factions, however, followed up on the ceasefire by taking advantage of the gradual Portuguese withdrawal to seize various strategic positions, acquire more arms, and enlarge their militant forces. The rapid influx of weapons from numerous external sources, especially the Soviet Union and the United States, as well as the escalation of tensions between the nationalist parties, fueled a new outbreak of hostilities. With tacit American and Zairean support the FNLA began massing large numbers of troops in northern Angola in an attempt to gain military superiority. Meanwhile, the MPLA began securing control of Luanda, a traditional Ambundu stronghold. Sporadic violence broke out in Luanda over the next few months after the FNLA attacked MPLA forces in March 1975. The fighting intensified with street clashes in April and May, and UNITA became involved after over two hundred of its members were massacred by an MPLA contingent that June. An upswing in Soviet arms shipments to the MPLA influenced a decision by the Central Intelligence Agency to likewise provide substantial covert aid to the FNLA and UNITA.In August 1975, the MPLA requested direct assistance from the Soviet Union in the form of ground troops. The Soviets declined, offering to send advisers but no troops; however, Cuba was more forthcoming and in late September dispatched nearly five hundred combat personnel to Angola, along with sophisticated weaponry and supplies. By independence there were over a thousand Cuban soldiers in the country. They were kept supplied by a massive airbridge carried out with Soviet aircraft. The persistent buildup of Cuban and Soviet military aid allowed the MPLA to drive its opponents from Luanda and blunt an abortive intervention by Zairean and South African troops, which had deployed in a belated attempt to assist the FNLA and UNITA. The FNLA was largely annihilated, although UNITA managed to withdraw its civil officials and militia from Luanda and seek sanctuary in the southern provinces. From there, Savimbi continued to mount a determined insurgent campaign against the MPLA. Between 1975 and 1991, the MPLA implemented an economic and political system based on the principles of scientific socialism, incorporating central planning and a Marxist–Leninist one-party state. It embarked on an ambitious programme of nationalisation, and the domestic private sector was essentially abolished. Privately owned enterprises were nationalised and incorporated into a single umbrella of state-owned enterprises known as Unidades Economicas Estatais (UEE). Under the MPLA, Angola experienced a significant degree of modern industrialisation. However, corruption and graft also increased and public resources were either allocated inefficiently or simply embezzled by officials for personal enrichment. The ruling party survived an attempted coup d'état by the Maoist-oriented Communist Organisation of Angola (OCA) in 1977, which was suppressed after a series of bloody political purges left thousands of OCA supporters dead.The MPLA abandoned its former Marxist ideology at its third party congress in 1990, and declared social democracy to be its new platform. Angola subsequently became a member of the International Monetary Fund; restrictions on the market economy were also reduced in an attempt to draw foreign investment. By May 1991 it reached a peace agreement with UNITA, the Bicesse Accords, which scheduled new general elections for September 1992. When the MPLA secured a major electoral victory, UNITA objected to the results of both the presidential and legislative vote count and returned to war. Following the election, the Halloween massacre occurred from October 30 to November 1, where MPLA forces killed thousands of UNITA supporters. === Ceasefire with UNITA === On 22 March 2002, Jonas Savimbi was killed in action against government troops. UNITA and the MPLA reached a cease-fire shortly afterwards. UNITA gave up its armed wing and assumed the role of a major opposition party. Although the political situation of the country began to stabilise, regular democratic processes did not prevail until the elections in Angola in 2008 and 2012 and the adoption of a new constitution in 2010, all of which strengthened the prevailing dominant-party system. Angola has a serious humanitarian crisis; the result of the prolonged war, of the abundance of minefields, of the continued political (and to a much lesser degree) military activities in favour of the independence of the exclave of Cabinda (carried out in the context of the protracted Cabinda Conflict by the Frente para a Libertação do Enclave de Cabinda, (FLEC)), but most of all, by the depredation of the country's rich mineral resources by the régime. While most of the internally displaced have now settled around the capital, in the so-called musseques, the general situation for Angolans remains desperate.Drought in 2016 caused the worst food crisis in Southern Africa in 25 years. Drought affected 1.4 million people across seven of Angola's 18 provinces. Food prices rose and acute malnutrition rates doubled, with more than 95,000 children affected. Food insecurity was expected to worsen from July to December 2016. == Geography == At 1,246,620 km2 (481,321 sq mi), Angola is the world's twenty-third largest country. It is comparable in size to Mali, or twice the size of France or Texas. It lies mostly between latitudes 4° and 18°S, and longitudes 12° and 24°E. Angola is bordered by Namibia to the south, Zambia to the east, the Democratic Republic of the Congo to the north-east and the South Atlantic Ocean to the west. The coastal exclave of Cabinda in the north, borders the Republic of the Congo to the north, and the Democratic Republic of the Congo to the south. Angola's capital, Luanda, lies on the Atlantic coast in the northwest of the country. Geography of Angola == Climate == Angola, although located in a tropical zone, has a climate that is not characterized for this region, due to the confluence of three factors: The Benguela Current, cold, along the southern part of the coast; The relief in the interior; Influence of the Namib Desert in the southwest.As a result, Angola's climate is characterized by two seasons: rainfall from October to April and drought, known as Cacimbo, from May to August, drier, as the name implies, and with lower temperatures. On the other hand, while the coastline has high rainfall rates, decreasing from North to South and from 800 mm to 50 mm, with average annual temperatures above 23 °C, the interior zone can be divided into three areas: North, with high rainfall and high temperatures; Central Plateau, with a dry season and average temperatures of the order of 19 °C; South with very high thermal amplitudes due to the proximity of the Kalahari Desert and the influence of masses of tropical air. == Politics == The Angolan government is composed of three branches of government: executive, legislative and judicial. The executive branch of the government is composed of the President, the Vice-Presidents and the Council of Ministers. The legislative branch comprises a 220-seat unicameral legislature elected from both provincial and nationwide constituencies. For decades, political power has been concentrated in the presidency. The Constitution of 2010 establishes the broad outlines of government structure and delineates the rights and duties of citizens. The legal system is based on Portuguese law and customary law but is weak and fragmented, and courts operate in only 12 of more than 140 municipalities. A Supreme Court serves as the appellate tribunal; a Constitutional Court does not hold the powers of judicial review. Governors of the 18 provinces are appointed by the president. After the end of the civil war the regime came under pressure from within as well as from the international community to become more democratic and less authoritarian. Its reaction was to implement a number of changes without substantially changing its character.Angola is classified as 'not free' by Freedom House in the Freedom in the World 2014 report. The report noted that the August 2012 parliamentary elections, in which the ruling Popular Movement for the Liberation of Angola won more than 70% of the vote, suffered from serious flaws, including outdated and inaccurate voter rolls. Voter turnout dropped from 80% in 2008 to 60%.Angola scored poorly on the 2013 Ibrahim Index of African Governance. It was ranked 39 out of 52 sub-Saharan African countries, scoring particularly badly in the areas of participation and human rights, sustainable economic opportunity and human development. The Ibrahim Index uses a number of variables to compile its list which reflects the state of governance in Africa. The new constitution, adopted in 2010, did away with presidential elections, introducing a system in which the president and the vice-president of the political party that wins the parliamentary elections automatically become president and vice-president. Directly or indirectly, the president controls all other organs of the state, so there is de facto no separation of powers. In the classifications used in constitutional law, this government falls under the category of authoritarian regime. On 16 October 2014, Angola was elected for the second time as a non-permanent member of the UN Security Council, with 190 favourable votes out of 193. The mandate began on 1 January 2015 and lasts for two years.Also that month, the country took on the leadership of the African ministers and governors at the International Monetary Fund and the World Bank, following debates at the annual meetings of both entities.Since January 2014 the Republic of Angola has held the rotating presidency of the International Conference on the Great Lakes Region (ICGLR). In 2015, the executive secretary of ICGLR, Ntumba Luaba, called Angola an example to be followed because of the significant progress it made over the 12 years of peace, particularly in terms of socioeconomic and political-military stability.After 38 years of rule, in 2017 President dos Santos stepped down from MPLA leadership. The leader of the winning party at the parliamentary elections in August 2017 become the next president of Angola. The MPLA selected Defense Minister General João Lourenço and won the election.In what has been described as a political purge to cement his power and reduce the influence of the Dos Santos family, Lourenço subsequently sacked the chief of the national police, Ambrósio de Lemos, and the head of the intelligence service, Apolinário José Pereira. Both are considered allies of former president Dos Santos. He also removed Isabel Dos Santos, daughter of the former president, as head of the country's state oil company Sonangol. === Armed forces === The Angolan Armed Forces (AAF) is headed by a Chief of Staff who reports to the Minister of Defence. There are three divisions—the Army (Exército), Navy (Marinha de Guerra, MGA) and National Air Force (Força Aérea Nacional, FAN). Total manpower is about 110,000. Its equipment includes Russian-manufactured fighters, bombers and transport planes. There are also Brazilian-made EMB-312 Tucanos for training, Czech-made L-39s for training and bombing, and a variety of western-made aircraft such as the C-212\Aviocar, Sud Aviation Alouette III, etc. A small number of AAF personnel are stationed in the Democratic Republic of the Congo (Kinshasa) and the Republic of the Congo (Brazzaville). === Police === The National Police departments are Public Order, Criminal Investigation, Traffic and Transport, Investigation and Inspection of Economic Activities, Taxation and Frontier Supervision, Riot Police and the Rapid Intervention Police. The National Police are in the process of standing up an air wing, to provide helicopter support for operations. The National Police are developing their criminal investigation and forensic capabilities. The force has an estimated 6,000 patrol officers, 2,500 taxation and frontier supervision officers, 182 criminal investigators and 100 financial crimes detectives and around 90 economic activity inspectors.The National Police have implemented a modernisation and development plan to increase the capabilities and efficiency of the total force. In addition to administrative reorganisation, modernisation projects include procurement of new vehicles, aircraft and equipment, construction of new police stations and forensic laboratories, restructured training programmes and the replacement of AKM rifles with 9 mm Uzis for officers in urban areas. === Justice === A Supreme Court serves as a court of appeal. The Constitutional Court is the supreme body of the constitutional jurisdiction, its Organic Law was approved by Law no. 2/08, of June 17, and The legal system is based on Portuguese and customary laws, but it is weak and fragmented. There are only 12 courts in more than 140 counties in the country. With the approval of Law no. 2/08, of June 17 – Organic Law of the Constitutional Court and Law n. 3/08, of June 17 – Organic Law of the Constitutional Process, the Legal Creation of the Constitutional Court. Its first task was the validation of the candidacies of the political parties to the legislative elections of 5 September 2008.Thus, on June 25, 2008, the Constitutional Court was institutionalized and its Judicial Counselors assumed the position before the President of the Republic. Currently, seven advisory judges are present, four men and three women. In 2014, a new penal code took effect in Angola. The classification of money-laundering as a crime is one of the novelties in the new legislation. === Foreign relations === On 16 October 2014, Angola was elected for the second time a non-permanent member of the United Nations Security Council, with 190 favorable votes out of a total of 193. The term of office begins on 1 January 2015 and lasts for two Years.Since January 2014, the Republic of Angola has been chairing the International Conference for the Great Lakes Region (CIRGL). [80] In 2015, CIRGL Executive Secretary Ntumba Luaba said that Angola is the example to be followed by the members of the organization, due to the significant progress made during the 12 years of peace, namely in terms of socio-economic stability and political- military. === Human rights === Homosexual acts are currently illegal in Angola. However, in February 2017, the Angolan Parliament approved a new penal code which does not outlaw homosexual acts. The law will take effect in late 2017. In 2010, the Angolan Government refused to receive openly gay Isi Yanouka as the new Israeli ambassador, allegedly due to his sexual orientation. == Administrative divisions == As of March 2016, Angola is divided into eighteen provinces (províncias) and 162 municipalities. The municipalities are further divided into 559 communes (townships). The provinces are: === Exclave of Cabinda === With an area of approximately 7,283 square kilometres (2,812 sq mi), the Northern Angolan province of Cabinda is unusual in being separated from the rest of the country by a strip, some 60 kilometres (37 mi) wide, of the Democratic Republic of Congo along the lower Congo River. Cabinda borders the Congo Republic to the north and north-northeast and the DRC to the east and south. The town of Cabinda is the chief population centre. According to a 1995 census, Cabinda had an estimated population of 600,000, approximately 400,000 of whom live in neighbouring countries. Population estimates are, however, highly unreliable. Consisting largely of tropical forest, Cabinda produces hardwoods, coffee, cocoa, crude rubber and palm oil. The product for which it is best known, however, is its oil, which has given it the nickname, "the Kuwait of Africa". Cabinda's petroleum production from its considerable offshore reserves now accounts for more than half of Angola's output. Most of the oil along its coast was discovered under Portuguese rule by the Cabinda Gulf Oil Company (CABGOC) from 1968 onwards. Ever since Portugal handed over sovereignty of its former overseas province of Angola to the local independence groups (MPLA, UNITA and FNLA), the territory of Cabinda has been a focus of separatist guerrilla actions opposing the Government of Angola (which has employed its armed forces, the FAA—Forças Armadas Angolanas) and Cabindan separatists. The Front for the Liberation of the Enclave of Cabinda-Armed Forces of Cabinda (FLEC-FAC) announced a virtual Federal Republic of Cabinda under the Presidency of N'Zita Henriques Tiago. One of the characteristics of the Cabindan independence movement is its constant fragmentation, into smaller and smaller factions. == Economy == Angola has diamonds, oil, gold, copper and a rich wildlife (dramatically impoverished during the civil war), forest and fossil fuels. Since independence, oil and diamonds have been the most important economic resource. Smallholder and plantation agriculture dramatically dropped in the Angolan Civil War, but began to recover after 2002. The transformation industry of the late colonial period collapsed at independence, because of the exodus of most of the ethnic Portuguese population, but it has begun to re-emerge with updated technologies, partly because of an influx of new Portuguese entrepreneurs. Similar developments have taken place in the service sector. Angola's economy has in recent years moved on from the disarray caused by a quarter-century of Angolan civil war to become the fastest-growing economy in Africa and one of the fastest-growing in the world, with an average GDP growth of 20% between 2005 and 2007. In the period 2001–10, Angola had the world's highest annual average GDP growth, at 11.1%. In 2004, the Exim Bank of China approved a $2 billion line of credit to Angola, to be used for rebuilding Angola's infrastructure, and to limit the influence of the International Monetary Fund there.China is Angola's biggest trade partner and export destination as well as the fourth-largest source of imports. Bilateral trade reached $27.67 billion in 2011, up 11.5% year-on-year. China's imports, mainly crude oil and diamonds, increased 9.1% to $24.89 billion while China's exports to Angola, including mechanical and electrical products, machinery parts and construction materials, surged 38.8%. The oil glut led to a local price for unleaded gasoline of £0.37 a gallon.The Economist reported in 2008 that diamonds and oil make up 60% of Angola's economy, almost all of the country's revenue and all of its dominant exports. Growth is almost entirely driven by rising oil production which surpassed 1.4 million barrels per day (220,000 m3/d) in late 2005 and was expected to grow to 2 million barrels per day (320,000 m3/d) by 2007. Control of the oil industry is consolidated in Sonangol Group, a conglomerate owned by the Angolan government. In December 2006, Angola was admitted as a member of OPEC.Operations in its diamond mines include partnerships between state-run Endiama and mining companies such as ALROSA which operate in Angola.The Angolan economy grew 18% in 2005, 26% in 2006 and 17.6% in 2007. Due to the global recession the economy contracted an estimated −0.3% in 2009. The security brought about by the 2002 peace settlement has allowed the resettlement of 4 million displaced persons and a resulting large-scale increases in agriculture production. Although the country's economy has grown significantly since Angola achieved political stability in 2002, mainly due to fast-rising earnings in the oil sector, Angola faces huge social and economic problems. These are in part a result of almost continual armed conflict from 1961 on, although the highest level of destruction and socio-economic damage took place after the 1975 independence, during the long years of civil war. However, high poverty rates and blatant social inequality chiefly stem from persistent authoritarianism, "neo-patrimonial" practices at all levels of the political, administrative, military and economic structures, and of a pervasive corruption. The main beneficiaries are political, administrative, economic and military power holders, who have accumulated (and continue to accumulate) enormous wealth."Secondary beneficiaries" are the middle strata which are about to become social classes. However, almost half the population has to be considered poor, with dramatic differences between the countryside and the cities (where by now slightly more than 50% of the people live). A study carried out in 2008 by the Angolan Instituto Nacional de Estatística found that in rural areas roughly 58% must be classified as "poor" according to UN norms, but in the urban areas only 19%, and an overall rate of 37%. In cities, a majority of families, well beyond those officially classified as poor, must adopt a variety of survival strategies. In urban areas social inequality is most evident and it's extreme in Luanda. In the Human Development Index Angola constantly ranks in the bottom group.According to the Heritage Foundation, a conservative American think tank, oil production from Angola has increased so significantly that Angola now is China's biggest supplier of oil. “China has extended three multibillion dollar lines of credit to the Angolan government; two loans of $2 billion from China Exim Bank, one in 2004, the second in 2007, as well as one loan in 2005 of $2.9 billion from China International Fund Ltd.”Growing oil revenues also created opportunities for corruption: according to a recent Human Rights Watch report, 32 billion US dollars disappeared from government accounts in 2007–2010. Furthermore, Sonangol, the state-run oil company, controls 51% of Cabinda’s oil. Due to this market control the company ends up determining the profit received by the government and the taxes it pays. The council of foreign affairs states that the World Bank mentioned that Sonangol " is a taxpayer, it carries out quasi-fiscal activities, it invests public funds, and, as concessionaire, it is a sector regulator. This multifarious work programme creates conflicts of interest and characterises a complex relationship between Sonangol and the government that weakens the formal budgetary process and creates uncertainty as regards the actual fiscal stance of the state."Before independence in 1975, Angola was a breadbasket of southern Africa and a major exporter of bananas, coffee and sisal, but three decades of civil war (1975–2002) destroyed fertile countryside, left it littered with landmines and drove millions into the cities. The country now depends on expensive food imports, mainly from South Africa and Portugal, while more than 90% of farming is done at the family and subsistence level. Thousands of Angolan small-scale farmers are trapped in poverty.The enormous differences between the regions pose a serious structural problem for the Angolan economy, illustrated by the fact that about one third of economic activities are concentrated in Luanda and neighbouring Bengo province, while several areas of the interior suffer economic stagnation and even regression.One of the economic consequences of the social and regional disparities is a sharp increase in Angolan private investments abroad. The small fringe of Angolan society where most of the asset accumulation takes place seeks to spread its assets, for reasons of security and profit. For the time being, the biggest share of these investments is concentrated in Portugal where the Angolan presence (including the family of the state president) in banks as well as in the domains of energy, telecommunications, and mass media has become notable, as has the acquisition of vineyards and orchards as well as of touristic enterprises.Sub-Saharan Africa nations are globally achieving impressive improvements in well-being, according to a report by Tony Blair's Africa Governance Initiative and the Boston Consulting Group. Angola has upgraded critical infrastructure, an investment made possible by funds from the nation's development of oil resources. According to this report, just slightly more than ten years after the end of the civil war Angola's standard of living has overall greatly improved. Life expectancy, which was just 46 years in 2002, reached 51 in 2011. Mortality rates for children fell from 25 percent in 2001 to 19 percent in 2010 and the number of students enrolled in primary school has tripled since 2001. However, at the same time the social and economic inequality that has characterised the country since long has not diminished, but on the contrary deepened in all respects. With a stock of assets corresponding to 70 billion Kz (6.8 billion USD), Angola is now the third largest financial market in sub-Saharan Africa, surpassed only by Nigeria and South Africa. According to the Angolan Minister of Economy, Abraão Gourgel, the financial market of the country grew modestly from 2002 and now lies in third place at the level of sub-Saharan Africa.Angola's economy is expected to grow by 3.9 percent in 2014 said the International Monetary Fund (IMF), robust growth in the non-oil economy, mainly driven by a very good performance in the agricultural sector, is expected to offset a temporary drop in oil production.Angola's financial system is maintained by the National Bank of Angola and managed by governor Jose de Lima Massano. According to a study on the banking sector, carried out by Deloitte, the monetary policy led by Banco Nacional de Angola (BNA), the Angolan national bank, allowed a decrease in the inflation rate put at 7.96% in December 2013, which contributed to the sector's growth trend. Estimates released by Angola's central bank, said country's economy should grow at an annual average rate of 5 percent over the next four years, boosted by the increasing participation of the private sector.On 19 December 2014, the Capital Market in Angola started. BODIVA (Angola Securities and Debt Stock Exchange, in English) received the secondary public debt market, and it is expected to start the corporate debt market by 2015, but the stock market should be a reality only in 2016. === Agriculture === Agriculture and forestry is an area of potential opportunity for the country. The African Economic Outlook organization states that “Angola requires 4.5 million tonnes a year of grain but grows only about 55% of the corn it needs, 20% of the rice and just 5% of its required wheat”. In addition, the World Bank estimates that “less than 3 percent of Angola's abundant fertile land is cultivated and the economic potential of the forestry sector remains largely unexploited" . === Transport === Transport in Angola consists of: Three separate railway systems totalling 2,761 km (1,716 mi) 76,626 km (47,613 mi) of highway of which 19,156 km (11,903 mi) is paved 1,295 navigable inland waterways Eight major sea ports 243 airports, of which 32 are paved.Travel on highways outside of towns and cities in Angola (and in some cases within) is often not best advised for those without four-by-four vehicles. While a reasonable road infrastructure has existed within Angola, time and the war have taken their toll on the road surfaces, leaving many severely potholed, littered with broken asphalt. In many areas drivers have established alternate tracks to avoid the worst parts of the surface, although careful attention must be paid to the presence or absence of landmine warning markers by the side of the road. The Angolan government has contracted the restoration of many of the country's roads. The road between Lubango and Namibe, for example, was completed recently with funding from the European Union, and is comparable to many European main routes. Completing the road infrastructure is likely to take some decades, but substantial efforts are already being made. Transport is an important aspect in Angola because it is strategically located and it could become a regional logistics hub. In addition Angola has some of the most important and biggest ports and so it is vital to connect them to the interior of the country as well as to neighbouring countries. Tourism is restarting on the heels of the long ended stop in the civil war, and very few tourists venture anywhere in Angola yet due to lack of infrastructure. === Telecommunications === The telecommunications industry is considered one of the main strategic sectors in Angola.In October 2014, the building of an optic fiber underwater cable was announced. This project aims to turn Angola into a continental hub, thus improving Internet connections both nationally and internationally.On 11 March 2015, the First Angolan Forum of Telecommunications and Information Technology was held in Luanda under the motto "The challenges of telecommunications in the current context of Angola", to promote debate on topical issues on telecommunications in Angola and worldwide. A study of this sector, presented at the forum, said Angola had the first telecommunications operator in Africa to test LTE – with speeds up to 400Mbit/s – and mobile penetration of about 75%; there are about 3.5 million smartphone in the Angolan market; There are about 25,000 kilometres (16,000 miles) of optical fibre installed in the country.The first Angolan satellite, AngoSat-1, will be ready for launch into orbit in 2017 and ensure telecommunications throughout the country. According to Aristides Safeca, Secretary of State for Telecommunications, the satellite will provide telecommunications services, TV, internet and e-government and will remain into orbit "at best" for 18 years. === Technology === The management of the top-level domain '.ao' will pass from Portugal to Angola in 2015, following new legislation. A joint decree of minister of Telecommunications and Information Technologies José Carvalho da Rocha and the minister of Science and Technology, Maria Cândida Pereira Teixeira, states that "under the massification" of that Angolan domain, "conditions are created for the transfer of the domain root '.ao' of Portugal to Angola". == Demographics == Angola has a population of 24,383,301 inhabitants according to the preliminary results of its 2014 census, the first one conducted or carried out since 15 December 1970. It is composed of Ovimbundu (language Umbundu) 37%, Ambundu (language Kimbundu) 23%, Bakongo 13%, and 32% other ethnic groups (including the Chokwe, the Ovambo, the Ganguela and the Xindonga) as well as about 2% mestiços (mixed European and African), 1.6% Chinese and 1% European. The Ambundu and Ovimbundu ethnic groups combined form a majority of the population, at 62%. The population is forecast to grow to over 60 million people to 2050, 2.7 times the 2014 population. However, on 23 March 2016, official data revealed by Angola's National Statistic Institute – Instituto Nacional de Estatística (INE), states that Angola has a population of 25.789.024 inhabitants. It is estimated that Angola was host to 12,100 refugees and 2,900 asylum seekers by the end of 2007. 11,400 of those refugees were originally from the Democratic Republic of Congo, who arrived in the 1970s. As of 2008 there were an estimated 400,000 Democratic Republic of the Congo migrant workers, at least 220,000 Portuguese, and about 259,000 Chinese living in Angola.Since 2003, more than 400,000 Congolese migrants have been expelled from Angola. Prior to independence in 1975, Angola had a community of approximately 350,000 Portuguese, but the vast majority left after independence and the ensuing civil war. However, Angola has recovered its Portuguese minority in recent years; currently, there are about 200,000 registered with the consulates, and increasing due to the debt crisis in Portugal and the relative prosperity in Angola. The Chinese population stands at 258,920, mostly composed of temporary migrants. Also, there is a small Brazilian community of about 5,000 people.The total fertility rate of Angola is 5.54 children born per woman (2012 estimates), the 11th highest in the world. === Languages === The languages in Angola are those originally spoken by the different ethnic groups and Portuguese, introduced during the Portuguese colonial era. The most widely spoken indigenous languages are Umbundu, Kimbundu and Kikongo, in that order. Portuguese is the official language of the country. Although the exact numbers of those fluent in Portuguese or who speak Portuguese as a first language are unknown, a 2012 study mentions that Portuguese is the first language of 39% of the population. In 2014, a census carried out by the Instituto Nacional de Estatística in Angola mentions that 71.15% of the nearly 25.8 million inhabitants of Angola (meaning around 18.3 million people) use Portuguese as a first or second language. === Religion === There are about 1,000 religious communities, mostly Christian, in Angola. While reliable statistics are nonexistent, estimates have it that more than half of the population are Catholics, while about a quarter adhere to the Protestant churches introduced during the colonial period: the Congregationalists mainly among the Ovimbundu of the Central Highlands and the coastal region to its west, the Methodists concentrating on the Kimbundu speaking strip from Luanda to Malanje, the Baptists almost exclusively among the Bakongo of the north-west (now present in Luanda as well) and dispersed Adventists, Reformed and Lutherans. In Luanda and region there subsists a nucleus of the "syncretic" Tocoists and in the north-west a sprinkling of Kimbanguism can be found, spreading from the Congo/Zaïre. Since independence, hundreds of Pentecostal and similar communities have sprung up in the cities, where by now about 50% of the population is living; several of these communities/churches are of Brazilian origin. As of 2008 the U.S. Department of State estimates the Muslim population at 80,000–90,000, less than 1% of the population, while the Islamic Community of Angola puts the figure closer to 500,000. Muslims consist largely of migrants from West Africa and the Middle East (especially Lebanon), although some are local converts. The Angolan government does not legally recognize any Muslim organizations and often shuts down mosques or prevents their construction.In a study assessing nations' levels of religious regulation and persecution with scores ranging from 0 to 10 where 0 represented low levels of regulation or persecution, Angola was scored 0.8 on Government Regulation of Religion, 4.0 on Social Regulation of Religion, 0 on Government Favoritism of Religion and 0 on Religious Persecution.Foreign missionaries were very active prior to independence in 1975, although since the beginning of the anti-colonial fight in 1961 the Portuguese colonial authorities expelled a series of Protestant missionaries and closed mission stations based on the belief that the missionaries were inciting pro-independence sentiments. Missionaries have been able to return to the country since the early 1990s, although security conditions due to the civil war have prevented them until 2002 from restoring many of their former inland mission stations.The Catholic Church and some major Protestant denominations mostly keep to themselves in contrast to the "New Churches" which actively proselytize. Catholics, as well as some major Protestant denominations, provide help for the poor in the form of crop seeds, farm animals, medical care and education. === Largest cities === == Culture == The substrate of Angolan culture is African, predominantly Bantu, while Portuguese culture has had a significant impact, specifically in terms of language and religion. The diverse ethnic communities – the Ovimbundu, Ambundu, Bakongo, Chokwe, Mbunda and other peoples – to varying degrees maintain their own cultural traits, traditions and languages, but in the cities, where slightly more than half of the population now lives, a mixed culture has been emerging since colonial times; in Luanda, since its foundation in the 16th century. In this urban culture, the Portuguese heritage has become more and more dominant. African roots are evident in music and dance, and is moulding the way in which Portuguese is spoken. This process is well reflected in contemporary Angolan literature, especially in the works of Angolan authors. In 2014, Angola resumed the National Festival of Angolan Culture after a 25-year break. The festival took place in all the provincial capitals and lasted for 20 days, with the theme Culture as a Factor of Peace and Development. == Health == Epidemics of cholera, malaria, rabies and African hemorrhagic fevers like Marburg hemorrhagic fever, are common diseases in several parts of the country. Many regions in this country have high incidence rates of tuberculosis and high HIV prevalence rates. Dengue, filariasis, leishmaniasis and onchocerciasis (river blindness) are other diseases carried by insects that also occur in the region. Angola has one of the highest infant mortality rates in the world and one of the world's lowest life expectancies. A 2007 survey concluded that low and deficient niacin status was common in Angola. Demographic and Health Surveys is currently conducting several surveys in Angola on malaria, domestic violence and more.In September 2014, the Angolan Institute for Cancer Control (IACC) was created by presidential decree, and it will integrate the National Health Service in Angola. The purpose of this new centre is to ensure health and medical care in oncology, policy implementation, programmes and plans for prevention and specialised treatment. This cancer institute will be assumed as a reference institution in the central and southern regions of Africa.In 2014, Angola launched a national campaign of vaccination against measles, extended to every child under ten years old and aiming to go to all 18 provinces in the country. The measure is part of the Strategic Plan for the Elimination of Measles 2014–2020 created by the Angolan Ministry of Health which includes strengthening routine immunisation, a proper dealing with measles cases, national campaigns, introducing a second dose of vaccination in the national routine vaccination calendar and active epidemiological surveillance for measles. This campaign took place together with the vaccination against polio and vitamin A supplementation.A yellow fever outbreak, the worst in the country in three decades began in December 2015. By August 2016, when the outbreak began to subside, nearly 4,000 people were suspected of being infected. As many as 369 may have died. The outbreak began in the capital, Luanda, and spread to at least 16 of the 18 provinces. == Education == Although by law education in Angola is compulsory and free for eight years, the government reports that a percentage of pupils are not attending due to a lack of school buildings and teachers. Pupils are often responsible for paying additional school-related expenses, including fees for books and supplies.In 1999, the gross primary enrollment rate was 74 percent and in 1998, the most recent year for which data are available, the net primary enrollment rate was 61 percent. Gross and net enrollment ratios are based on the number of pupils formally registered in primary school and therefore do not necessarily reflect actual school attendance. There continue to be significant disparities in enrollment between rural and urban areas. In 1995, 71.2 percent of children ages 7 to 14 years were attending school. It is reported that higher percentages of boys attend school than girls. During the Angolan Civil War (1975–2002), nearly half of all schools were reportedly looted and destroyed, leading to current problems with overcrowding.The Ministry of Education recruited 20,000 new teachers in 2005 and continued to implement teacher trainings. Teachers tend to be underpaid, inadequately trained and overworked (sometimes teaching two or three shifts a day). Some teachers may reportedly demand payment or bribes directly from their pupils. Other factors, such as the presence of landmines, lack of resources and identity papers, and poor health prevent children from regularly attending school. Although budgetary allocations for education were increased in 2004, the education system in Angola continues to be extremely under-funded.According to estimates by the UNESCO Institute for Statistics, the adult literacy rate in 2011 was 70.4%. By 2015, this had increased to 71.1%. 82.9% of males and 54.2% of women are literate as of 2001. Since independence from Portugal in 1975, a number of Angolan students continued to be admitted every year at high schools, polytechnical institutes and universities in Portugal, Brazil and Cuba through bilateral agreements; in general, these students belong to the elites. In September 2014, the Angolan Ministry of Education announced an investment of 16 million Euros in the computerisation of over 300 classrooms across the country. The project also includes training teachers at a national level, "as a way to introduce and use new information technologies in primary schools, thus reflecting an improvement in the quality of teaching."In 2010, the Angolan government started building the Angolan Media Libraries Network, distributed throughout several provinces in the country to facilitate the people's access to information and knowledge. Each site has a bibliographic archive, multimedia resources and computers with Internet access, as well as areas for reading, researching and socialising. The plan envisages the establishment of one media library in each Angolan province by 2017. The project also includes the implementation of several media libraries, in order to provide the several contents available in the fixed media libraries to the most isolated populations in the country. At this time, the mobile media libraries are already operating in the provinces of Luanda, Malanje, Uíge, Cabinda and Lunda South. As for REMA, the provinces of Luanda, Benguela, Lubango and Soyo have currently working media libraries. == Sports == Basketball is the most popular sport in Angola. Its national team has won the AfroBasket 11 times and holds the record of most titles. As a top team in Africa, it's a regular competitor at the Summer Olympic Games and the FIBA World Cup. In football, Angola hosted the 2010 Africa Cup of Nations. The Angola national football team qualified for the 2006 FIFA World Cup, as this was their first appearance on the World Cup finals stage. They were eliminated after one defeat and two draws in the group stage. They won 3 COSAFA Cups and finished runner up in 2011 African Nations Championship. Angola has participated in the World Women's Handball Championship for several years. The country has also appeared in the Summer Olympics for seven years and both regularly competes in and once has hosted the FIRS Roller Hockey World Cup, where the best finish is sixth. Angola is also often believed to have historic roots in the martial art "Capoeira Angola" and "Batuque" which were practiced by enslaved African Angolans transported as part of the Atlantic slave trade. == See also == Outline of Angola Index of Angola-related articles == Notes == == References == Baynes, T.S., ed.

### Instruction: retrieve labels for this: This article is about the demographic features of the population of Angola, including population density, ethnicity, education level, health of the populace, economic status, religious affiliations and other aspects of the population. According to 2014 census data, Angola had a population of 25,789,024 inhabitants in 2014. Ethnically, there are three main groups, each speaking a Bantu language: the Ovimbundu who represent 37% of the population, the Ambundu with 25%, and the Bakongo 13%. Other numerically important groups include the closely interrelated Chokwe and Lunda, the Ganguela and Nyaneka-Khumbi (in both cases classification terms that stand for a variety of small groups), the Ovambo, the Herero, the Xindonga and scattered residual groups of San. In addition, mixed race (European and African) people amount to about 2%, with a small (1%) population of whites, mainly ethnically Portuguese. As a former overseas territory of Portugal until 1975, Angola possesses a Portuguese population of over 200,000, a number that has been growing from 2000 onwards, because of Angola's growing demand for qualified human resources. Besides the Portuguese, significant numbers of people from other European and from diverse Latin American countries (especially Brazil) can be found. From the 2000s, many Chinese have settled and started up small businesses, while at least as many have come as workers for large enterprises (construction or other). Observers claim that the Chinese community in Angola might include as many as 300,000 persons at the end of 2010, but reliable statistics are not at this stage available. In 1974/75, over 25,000 Cuban soldiers arrived in Angola to help the MPLA forces at the beginning of the Angolan Civil War. Once this was over, a massive development cooperation in the field of health and education brought in numerous civil personnel from Cuba. However, only a very small percentage of all these people has remained in Angola, either for personal reasons (intermarriage) or as professionals (e.g., medical doctors). The largest religious denomination is Catholicism, to which adheres about half the population. Roughly 26% are followers of traditional forms of Protestantism (Congregationals, Methodists, Baptista, Lutherans, Reformed), but over the last decades there has in addition been a growth of Pentecostal communities and African Initiated Churches. In 2006, one out of 221 people were Jehovah's Witnesses. Blacks from Mali, Nigeria and Senegal are mostly Sunnite Muslims, but do not make up more than 1 - 2% of the population. By now few Angolans retain African traditional religions following different ethnic faiths. == Population == According to the 2017 revision of the World Population Prospects the total population was 28,813,463 in 2016, compared to only 4 148 000 in 1950. The proportion of children below the age of 15 in 2010 was 46.6%, 50.9% was between 15 and 65 years of age, while 2.5% was 65 years or older . Structure of the population (DHS 2011) (Males 19 707, Females 20 356 = 40 063) : == Vital statistics == Registration of vital events is in Angola not complete. The Population Department of the United Nations prepared the following estimates. === Fertility and Births === Total Fertility Rate (TFR) (Wanted TFR) and Crude Birth Rate (CBR): == CIA World Factbook demographic statistics == The following demographic statistics are from the CIA World Factbook, unless otherwise indicated. === Population === 18,056,072 (July 2012 est.) ==== Population growth ==== The population is growing by 2.184% annually. There are 44.51 births and 24.81 deaths per 1,000 citizens. The net migration rate is 2.14 migrants per 1,000 citizens. The fertility rate of Angola is 5.97 children born per woman as of 2011. The infant mortality rate is 184.44 deaths for every 1,000 live births with 196.55 deaths for males and 171.72 deaths for females for every 1,000 live births. Life expectancy at birth is 37.63 years; 36.73 years for males and 38.57 years for females. === Sex ratio === At birth: 1.05 male(s)/female Under 15 years: 1.02 male(s)/female 15–64 years: 1.03 male(s)/female 65 years and older: .79 male(s)/female Total population: 1.02 male(s)/female (2011 est.) === Health === According to the CIA World Factbook, 2% of adults (aged 15–49) are living with HIV/AIDS (as of 2009). The risk of contracting disease is very high. There are food and waterborne diseases, bacterial and protozoal diarrhea, hepatitis A, and typhoid fever; vectorborne diseases, malaria, African trypanosomiasis (sleeping sickness); respiratory disease: meningococcal meningitis, and schistosomiasis, a water contact disease, as of 2005. === Ethnic groups === Roughly 37% of Angolans are Ovimbundu, 25% are Ambundu, 13% are Bakongo, 2% are mestiço, 1-2% are white Africans, and people from other African ethnicities make up 22% of Angola's population. === Religions === Angola is a majority Christian country. Official statistics don't exist, but it is estimated that over 80% belong to a Christian church or community. More than half are Catholic, the remaining ones comprising members of traditional Protestant churches as well as of Pentecostal communities. Only 1 - 2% are Muslims - generally immigrants from other African countries. Traditional indigenous religions are practized by a very small minority, generally in peripheral rural societies. === Education === Literacy is quite low, with 67.4% of the population over the age of 15 able to read and write in Portuguese. 82.9% of males and 54.2% of women are literate as of 2001. === Languages === Portuguese is the official language of Angola, but Bantu and other African languages are also widely spoken. In fact, Kikongo, Kimbundu, Umbundu, Tuchokwe, Nganguela, and Ukanyama have the official status of "national languages". The mastery of Portuguese is widespread; in the cities the overwhelming majority are either fluent in Portuguese or have at least a reasonable working knowledge of this language; an increasing minority are native Portuguese speakers and have a poor, if any, knowledge of an African language. == References == This article incorporates public domain material from the CIA World Factbook document "2007 edition".

### Instruction: retrieve labels for this: Since the adoption of a new constitution in 2010, the politics of Angola takes place in a framework of a presidential republic, whereby the President of Angola is both head of state and head of government, and of a multi-party system. Executive power is exercised by the government. Legislative power is vested in the President, the government and parliament.Angola changed from a one-party Marxist-Leninist system ruled by the Popular Movement for the Liberation of Angola (MPLA), in place since independence in 1975, to a multiparty democracy based on a new constitution adopted in 1992. That same year the first parliamentary and presidential elections were held. The MPLA won an absolute majority in the parliamentary elections. In the presidential elections, President José Eduardo dos Santos won the first round election with more than 49% of the vote to Jonas Savimbi's 40%. A runoff election would have been necessary, but never took place. The renewal of civil war immediately after the elections, which were considered as fraudulent by UNITA, and the collapse of the Lusaka Protocol, created a split situation. To a certain degree the new democratic institutions worked, notably the National Assembly, with the active participation of UNITA's and the FNLA's elected MPs - while José Eduardo dos Santos continued to exercise his functions without democratic legitimation. However the armed forces of the MPLA (now the official armed forces of the Angolan state) and of UNITA fought each other until the leader of UNITA, Jonas Savimbi, was killed in action in 2002.From 2002 to 2010, the system as defined by the constitution of 1992 functioned in a relatively normal way. The executive branch of the government was composed of the President, the Prime Minister and Council of Ministers. The Council of Ministers, composed of all ministers and vice ministers, met regularly to discuss policy issues. Governors of the 18 provinces were appointed by and served at the pleasure of the president. The Constitutional Law of 1992 established the broad outlines of government structure and the rights and duties of citizens. The legal system was based on Portuguese and customary law but was weak and fragmented. Courts operated in only 12 of more than 140 municipalities. A Supreme Court served as the appellate tribunal; a Constitutional Court with powers of judicial review was never constituted despite statutory authorization. In practice, power was more and more concentrated in the hands of the President who, supported by an ever-increasing staff, largely controlled parliament, government, and the judiciary.The 26-year-long civil war has ravaged the country's political and social institutions. The UN estimates of 1.8 million internally displaced persons (IDPs), while generally the accepted figure for war-affected people is 4 million. Daily conditions of life throughout the country and specifically Luanda (population approximately 6 million) mirror the collapse of administrative infrastructure as well as many social institutions. The ongoing grave economic situation largely prevents any government support for social institutions. Hospitals are without medicines or basic equipment, schools are without books, and public employees often lack the basic supplies for their day-to-day work. == Executive branch == The 2010 constitution grants the President almost absolute power. Elections for the National assembly are to take place every five years, and the President is automatically the leader of the winning party or coalition. It is for the President to appoint (and dismiss) all of the following: The members of the government (state ministers, ministers, state secretaries and vice-ministers); The members of the Constitutional Court; The members of the Supreme Court; The members of the Court of Auditors; The members of the Military Supreme Court; The Governor and Vice-Governors of the Nacional Angolan Bank; The General-Attorney, the Vice-General-Attorneys and their deputies (as well as the military homologous); The Governors of the provinces; The members of the Republic Council; The members of the National Security Council; The members of the Superior Magistrates Councils; The General Chief of the Armed Forces and his deputy; All other command posts in the military; The Police General Commander, and the 2nd in command; All other command posts in the police; The chiefs and directors of the intelligence and security organs.The President is also provided a variety of powers, like defining the policy of the country. Even though it's not up to him/her to make laws (only to promulgate them and make edicts), the President is the leader of the winning party. The only "relevant" post that is not directly appointed by the President is the Vice-President, which is the second in the winning party. == Legislative branch == The National Assembly (Assembleia Nacional) has 223 members, elected for a four-year term, 130 members by proportional representation, 90 members in provincial districts, and 3 members to represent Angolans abroad. The next general elections, due for 1997, have been rescheduled for 5 September 2008. The ruling party MPLA won 82% (191 seats in the National Assembly) and the main opposition party won only 10% (16 seats). The elections however have been described as only partly free but certainly not fair. A White Book on the elections in 2008 lists up all irregularities surrounding the Parliamentary elections of 2008. == Political parties and elections == == Judicial branch == Supreme Court (or "Tribunal da Relacao") judges of the Supreme Court are appointed by the president. The Constitutional Court, with the power of judicial review, contains 11 justices. Four are appointed by the President, four by the National Assembly, two by the Superior Council of the Judiciary, and one elected by the public. == Administrative divisions == Angola has eighteen provinces (provincias, singular - provincia); Bengo, Benguela, Bie, Cabinda, Cuando Cubango, Cuanza Norte, Cuanza Sul, Cunene, Huambo, Huila, Luanda, Lunda Norte, Lunda Sul, Malanje, Moxico, Namibe, Uige, Zaire == Political pressure groups and leaders == Front for the Liberation of the Enclave of Cabinda or FLEC (Henrique N'zita Tiago; António Bento Bembe) note: FLEC is waging a small-scale, highly factionalized, armed struggle for the independence of Cabinda Province == International organization participation == African, Caribbean and Pacific Group of States, AfDB, CEEAC, United Nations Economic Commission for Africa, FAO, Group of 77, IAEA, IBRD, ICAO, International Criminal Court (signatory), ICFTU, International Red Cross and Red Crescent Movement, International Development Association, IFAD, IFC, IFRCS, International Labour Organization, International Monetary Fund, International Maritime Organization, Interpol, IOC, International Organization for Migration, ISO (correspondent), ITU, Non-Aligned Council (temporary), UNCTAD, UNESCO, UNIDO, UPU, World Customs Organization, World Federation of Trade Unions, WHO, WIPO, WMO, WToO, WTrO == See also == Government of the Republic of Angola == References == == Further reading == ANGOLA LIVRO BRANCO SOBRE AS ELEIÇÕES DE 2008. http://www.kas.de/proj/home/pub/8/2/year-2009/dokument_id-17396/index.html Bösl, Anton (2008).

### Instruction: retrieve labels for this: The Angolan Armed Forces (Portuguese: Forças Armadas Angolanas) or FAA are the military of Angola. The FAA include the General Staff of the Armed Forces and three components: the Army (Exército), the Navy (Marinha de Guerra) and the National Air Force (National Air Force). Reported total manpower in 2013 was about 107,000.The FAA is headed by Chief of the General Staff Geraldo Sachipengo Nunda since 2010, who reports to the Minister of National Defense, currently Salviano de Jesus Sequeira. == History == The FAA succeeded to the previous People's Armed Forces for the Liberation of Angola (FAPLA) following the abortive Bicesse Accord with the Armed Forces of the Liberation of Angola (FALA), armed wing of the National Union for the Total Independence of Angola (UNITA). As part of the peace agreement, troops from both armies were to be demilitarized and then integrated. Integration was never completed as UNITA and FALA went back to war in 1992. Later, consequences for FALA personnel in Luanda were harsh with FAPLA veterans persecuting their erstwhile opponents in certain areas and reports of vigilantism. == Army == === General description === The Army (Exército) is the land component of the FAA. It is organized in six military regions (Cabinda, Luanda, North, Center, East and South), with an infantry division being based in each one. Distributed by the six military regions / infantry divisions, there are 25 motorized infantry brigades, one tank brigade and one engineering brigade. The Army also includes an artillery regiment, the Military Artillery School, the Army Military Academy, an anti-aircraft defense group, a composite land artillery group, a military police regiment, a logistical transportation regiment and a field artillery brigade. The Army further includes the Special Forces Brigade (including Commandos and Special Operations units), but this unit is under the direct command of the General Staff of the FAA. === History === On August 1, 1974 a few months after a military coup d'état had overthrown the Lisbon regime and proclaimed its intention of granting independence to Angola, the MPLA announced the formation of FAPLA, which replaced the EPLA. By 1976 FAPLA had been transformed from lightly armed guerrilla units into a national army capable of sustained field operations.In 1990-91, the Army had ten military regions and an estimated 73+ 'brigades', each with a mean strength of 1,000 and comprising inf, tank, APC, artillery, and AA units as required. The Library of Congress said in 1990 that '[t]he regular army's 91,500 troops were organized into more than seventy brigades ranging from 750 to 1,200 men each and deployed throughout the ten military regions. Most regions were commanded by lieutenant colonels, with majors as deputy commanders, but some regions were commanded by majors. Each region consisted of one to four provinces, with one or more infantry brigades assigned to it. The brigades were generally dispersed in battalion or smaller unit formations to protect strategic terrain, urban centers, settlements, and critical infrastructure such as bridges and factories. Counterintelligence agents were assigned to all field units to thwart UNITA infiltration. The army's diverse combat capabilities were indicated by its many regular and motorised infantry brigades with organic or attached armor, artillery, and air defense units; two militia infantry brigades; four antiaircraft artillery brigades; ten tank battalions; and six artillery battalions. These forces were concentrated most heavily in places of strategic importance and recurring conflict: the oil-producing Cabinda Province, the area around the capital, and the southern provinces where UNITA and South African forces operated.' It was reported in 2011 that the army was by far the largest of the services with about 120,000 men and women. The Angolan Army has around 29,000 "ghost workers" who remain enrolled in the ranks of the FAA and therefore receive a salary.In 2013, the International Institute for Strategic Studies reported that the FAA had six divisions, the 1st, 5th, and 6th with two or three infantry brigades, and the 2nd, 3rd, and 4th with five to six infantry brigades. The 4th Division included a tank regiment. A separate tank brigade and special forces brigade were also reported.As of 2011, the IISS reported the ground forces had 42 armoured/infantry regiments ('detachments/groups - strength varies') and 16 infantry 'brigades'. These probably comprised infantry, tanks, APC, artillery, and AA units as required. Major equipment included over 140 main battle tanks, 600 reconnaissance vehicles, over 920 AFVs, infantry fighting vehicles, 298 howitzers.It was reported on May 3, 2007, that the Special Forces Brigade of the Angolan Armed Forces (FAA) located at Cabo Ledo region, northern Bengo Province, would host a 29th anniversary celebration for the entire armed forces. The brigade was reportedly formed on 5 May 1978 and under the command at the time of Colonel Paulo Falcao. === Equipment === The Army operates a large amount of Russian, Soviet and ex-Warsaw pact hardware. A large amount of its equipment was acquired in the 1980s and 1990s most likely because of hostilities with neighbouring countries and its civil war which lasted from November 1975 until 2002. There is an interest from the Angolan Army for the Brazilian ASTROS II multiple rocket launcher. ==== Infantry Weapons ==== Many of Angola's weapons are of Portuguese colonial and Warsaw Pact origin. Jane's Information Group lists the following as in service: Rifles in service with Army include the AK-47, AKM, FN FAL, G3 Assault Rifle, SKS and IMI Tavor. Pistols include the Makarov pistol, Stechkin automatic pistol and the Tokarev TT pistol. Submachine guns include the Škorpion vz. 61, Star Z-45, Uzi and the FBP submachine gun. Machine guns include the RP-46, RPD machine gun, Vz. 52 machine gun and the DShK Heavy machine gun. Grenade launchers include the AGS-17 automatic grenade launcher. Mortars include the 120-PM-43 mortar (500 in service) and the 82-PM-41 (250 in service). Anti-Tank weapons include the RPG-7, 9K111 Fagot (650 ordered in 1987), 9K11 Malyutka, B-10 recoilless rifle and the B-11 recoilless rifle. ==== Main Battle Tanks ==== Between 116 and 267 T-55AM-2 Medium tanks. 281 T-55's were ordered between 1975 and 1999. 267 T-55AM-2's were delivered from Bulgaria and Slovakia in 1999. 50 T-72M1 main battle tanks. Delivered from Belarus in 1999. 50 T-62 Main battle tanks. 364 were ordered in the 1980s and 1990s. 12 PT-76 Amphibious Light tanks. 68 ordered in 1975 from the Soviet Union. ==== Armoured Vehicles ==== 150 BMP-1 infantry fighting vehicles. 100 BMP-2 infantry fighting vehicles. 10 BMD-3 infantry fighting vehicles. 195 BRDM-2 and 120 BRDM-1 Amphibious Armoured Scout Cars. 62 BTR-60 and 50 OT-62 TOPAS armored personnel carriers 45 Casspir NG 2000B Infantry mobility vehicles 24 EE-11 Urutu armored personnel carriers ==== Artillery ==== 12 2S1 Gvozdika 122 mm Self-propelled guns (Acquired in 2000 from the Czech Republic). 4 2S3 Akatsiya 152 mm Self-propelled guns (Acquired in 1999 from the Bulgaria). 12 2S7 Pion 203 mm Self-propelled guns (Acquired in 2000 from the Czech Republic). Unknown amounts of M1942 ZiS-3 Anti-tank field guns ~280 D-30 122 mm Howitzers (28 from Kazakhstan in 1998, 12 from Belarus, 240 from the Soviet Union in the 1980s) 4 D-20 Howitzers. Unknown amounts of 85 mm divisional gun D-44 Field Guns. 48 M-46 130 mm field guns 75 BM-21 Grad multiple rocket launchers 40 RM-70 multiple rocket launchers ==== Anti-Aircraft weaponry ==== 20 ZSU-23-4 Shilka Self-propelled anti-aircraft guns. 40 ZSU-57-2 Self-propelled anti-aircraft guns Unknown amounts of ZU-23-2, 57 mm AZP S-60, M-1939, ZPU-4 and Zastava M55 anti-aircraft guns. 40 SA-2 Guideline high-altitude air defense systems. 12 SA-3 Goa 25 SA-6 Unknown amounts of SA-7 Grail 15 SA-8 20 SA-9 Gaskin 10 SA-13 Unknown amounts of SA-14 Gremlin and SA-16 Gimlet. ==== Other Vehicles ==== Ural-4320 trucks Star 266 KrAZ-6322 == Air Force == The National Air Force of Angola (FANA, Força Aérea Nacional de Angola) is the air component of the FAA. It is organized in six aviation regiments, each including several squadrons. To each of the regiments correspond an air base. Besides the aviation regiments, there is also a Pilot Training School. The Air Force's personnel total about 8,000; its equipment includes transport aircraft and six Russian-manufactured Sukhoi Su-27 fighter aircraft. In 2002 one was lost during the civil war with UNITA forces.In 1991, the Air Force/Air Defense Forces had 8,000 personnel and 90 combat-capable aircraft, including 22 fighters, 59 fighter ground attack aircraft and 16 attack helicopters. == Navy == The Angola Navy (MGA, Marinha de Guerra de Angola) is the naval component of the FAA. It is organized in two naval zones (North and South), with naval bases in Luanda, Lobito and Namibe. It includes a Marines Brigade and a Marines School, based in Ambriz. The Navy numbers about 1,000 personnel and operates only a handful of small patrol craft and barges. The Navy has been neglected and ignored as a military arm mainly due to the guerrilla struggle against the Portuguese and the nature of the civil war. From the early 1990s to the present the Angolan Navy has shrunk from around 4,200 personnel to around 1,000, resulting in the loss of skills and expertise needed to maintain equipment. In order to protect Angola’s 1 600 km long coastline, the Angolan Navy is undergoing modernisation but is still lacking in many ways. Portugal has been providing training through its Technical Military Cooperation (CTM) programme. The Navy is requesting procurement of a frigate, three corvettes, three offshore patrol vessel and additional fast patrol boats. Most of the vessels in the navy's inventory dates back from the 1980s or earlier, and many of its ships are inoperable due to age and lack of maintenance. However the navy acquired new boats from Spain and France in the 1990s. Germany has delivered several Fast Attack Craft for border protection in 2011. In September 2014 it was reported that the Angolan Navy would acquire seven Macaé-class patrol vessels from Brazil as part of a Technical Memorandum of Understanding (MoU) covering the production of the vessels as part of Angola’s Naval Power Development Programme (Pronaval). The military of Angola aims to modernize its naval capability, presumably due to a rise in maritime piracy within the Gulf of Guinea which may have an adverse effect on the country's economy. The navy's current known inventory includes the following: Fast attack craft 4 Mandume class craft (Bazan Cormoran type, refurbished in 2009) Patrol Boats 3 18.3m long Patrulheiro patrol boats (refurbished in 2002) 5 ARESA PVC-170 2 Namacurra-class harbour patrol boats Fisheries Patrol Boats Ngola Kiluange and Nzinga Mbandi (delivered in September and October 2012 from Damen Shipyards)(Operated by Navy personnel under the Ministry of Agriculture, Rural Development and Fisheries) 28 metre FRV 2810 (Pensador) (Operated by Navy personnel under the Ministry of Agriculture, Rural Development and Fisheries) Landing craft LDM-400 - 1 or 3 (reportedly has serviceability issues) Coastal defense equipment (CRTOC) SS-C1 Sepal radar systemThe navy also has several aircraft for maritime patrol: == Special forces == The FAA include several types of special forces, namely the Commandos, the Special Operations and the Marines. The Angolan special forces follow the general model of the analogous Portuguese special forces, receiving a similar training. The Commandos and the Special forces are part of the Special Forces Brigade (BRIFE, Brigada de Forças Especiais), based at Cabo Ledo, in the Bengo Province. The BRIFE includes two battalions of commandos, a battalion of special operations and sub-units of combat support and service support. The BRIFE also included the Special Actions Group (GAE, Grupo de Ações Especiais), which is presently inactive and that was dedicated to long range reconnaissance, covert and sabotage operations. In the Cabo Ledo base is also installed the Special Forces Training School (EFFE, Escola de Formação de Forças Especiais). Both the BRIFE and the EFFE are directly under the Directorate of Special Forces of the General Staff of the Armed Forces. The marines (fuzileiros navais) constitute the Marines Brigade of the Angolan Navy. The Marines Brigade is not permanently dependent of the Directorate of Special Forces, but can detach their units and elements to be put under the command of that body for the conduction of exercises or real operations. Since the disbandment of the Angolan Parachute Battalion in 2004, the FAA do not have a specialized paratrooper unit. However, elements of the commandos, special operations and marines are parachute qualified. == Foreign deployments == The FAPLA's main counterinsurgency effort was directed against UNITA in the southeast, and its conventional capabilities were demonstrated principally in the undeclared South African Border War. The FAPLA first performed its external assistance mission with the dispatch of 1,000 to 1,500 troops to São Tomé and Príncipe in 1977 to bolster the socialist regime of President Manuel Pinto da Costa. During the next several years, Angolan forces conducted joint exercises with their counterparts and exchanged technical operational visits. The Angolan expeditionary force was reduced to about 500 in early 1985. The Angolan Armed Forces were controversially involved in training the armed forces of fellow Lusophone states Cape Verde and Guinea-Bissau. In the case of the latter, the 2012 Guinea-Bissau coup d'état was cited by the coup leaders as due to Angola's involvement in trying to "reform" the military in connivance with the civilian leadership. A small number of FAA personnel are stationed in the Democratic Republic of the Congo (Kinshasa) and the Republic of the Congo (Brazzaville). A presence during the unrest in Ivory Coast, 2010–2011, were not officially confirmed. However, the Frankfurter Allgemeine Zeitung, citing Jeune Afrique, said that among President Gbagbo's guards were 92 personnel of President Dos Santos's Presidential Guard Unit. Angola is basically interested in the participation of the FAA operations of the African Union and has formed special units for this purpose. == References == == Further reading == "World Defence Almanac".

### Instruction: retrieve labels for this: Alberta ( ( listen)) is a western province of Canada. With an estimated population of 4,067,175 as of 2016 census, it is Canada's fourth most populous province and the most populous of Canada's three prairie provinces. Its area is about 660,000 square kilometres (250,000 sq mi). Alberta and its neighbour Saskatchewan were districts of the Northwest Territories until they were established as provinces on September 1, 1905. The premier has been Rachel Notley since May 2015. Alberta is bounded by the provinces of British Columbia to the west and Saskatchewan to the east, the Northwest Territories to the north, and the U.S. state of Montana to the south. Alberta is one of three Canadian provinces and territories to border only a single U.S. state and one of only two landlocked provinces. It has a predominantly humid continental climate, with stark contrasts over a year; but seasonal temperature average swings are smaller than in areas further east, due to winters being warmed by occasional chinook winds bringing sudden warming.Alberta's capital, Edmonton, is near the geographic centre of the province and is the primary supply and service hub for Canada's crude oil, the Athabasca oil sands and other northern resource industries.About 290 km (180 mi) south of the capital is Calgary, the largest city in Alberta. Calgary and Edmonton centre Alberta's two census metropolitan areas, both of which have populations exceeding one million, while the province has 16 census agglomerations.Tourist destinations in the province include Banff, Canmore, Drumheller, Jasper, Sylvan Lake and Lake Louise. == Etymology == Alberta is named after Princess Louise Caroline Alberta (1848–1939), the fourth daughter of Queen Victoria. Princess Louise was the wife of John Campbell, Marquess of Lorne, Governor General of Canada (1878–83). Lake Louise and Mount Alberta were also named in her honour. == Geography == Alberta, with an area of 661,848 km2 (255,500 sq mi), is the fourth-largest province after Quebec, Ontario and British Columbia.To the south, the province borders on the 49th parallel north, separating it from the U.S. state of Montana, while to the north the 60th parallel north divides it from the Northwest Territories. To the east, the 110th meridian west separates it from the province of Saskatchewan, while on the west its boundary with British Columbia follows the 120th meridian west south from the Northwest Territories at 60°N until it reaches the Continental Divide at the Rocky Mountains, and from that point follows the line of peaks marking the Continental Divide in a generally southeasterly direction until it reaches the Montana border at 49°N.The province extends 1,223 km (760 mi) north to south and 660 km (410 mi) east to west at its maximum width. Its highest point is 3,747 m (12,293 ft) at the summit of Mount Columbia in the Rocky Mountains along the southwest border while its lowest point is 152 m (499 ft) on the Slave River in Wood Buffalo National Park in the northeast.With the exception of the semi-arid steppe of the south-eastern section, the province has adequate water resources. There are numerous rivers and lakes used for swimming, fishing and a range of water sports. There are three large lakes, Lake Claire (1,436 km2 (554 sq mi)) in Wood Buffalo National Park, Lesser Slave Lake (1,168 km2 (451 sq mi)), and Lake Athabasca (7,898 square kilometres (3,049 sq mi)) which lies in both Alberta and Saskatchewan. The longest river in the province is the Athabasca River which travels 1,538 km (956 mi) from the Columbia Icefield in the Rocky Mountains to Lake Athabasca.The largest river is the Peace River with an average flow of 2161 m3/s. The Peace River originates in the Rocky Mountains of northern British Columbia and flows through northern Alberta and into the Slave River, a tributary of the Mackenzie River. Alberta's capital city, Edmonton, is located at about the geographic centre of the province. It is the most northerly major city in Canada, and serves as a gateway and hub for resource development in northern Canada. The region, with its proximity to Canada's largest oil fields, has most of western Canada's oil refinery capacity. Calgary is about 280 km (170 mi) south of Edmonton and 240 km (150 mi) north of Montana, surrounded by extensive ranching country. Almost 75% of the province's population lives in the Calgary–Edmonton Corridor. The land grant policy to the railroads served as a means to populate the province in its early years.Most of the northern half of the province is boreal forest, while the Rocky Mountains along the southwestern boundary are largely forested (see Alberta Mountain forests and Alberta-British Columbia foothills forests). The southern quarter of the province is prairie, ranging from shortgrass prairie in the southeastern corner to mixed grass prairie in an arc to the west and north of it. The central aspen parkland region extending in a broad arc between the prairies and the forests, from Calgary, north to Edmonton, and then east to Lloydminster, contains the most fertile soil in the province and most of the population. Much of the unforested part of Alberta is given over either to grain or to dairy farming, with mixed farming more common in the north and centre, while ranching and irrigated agriculture predominate in the south.The Alberta badlands are located in southeastern Alberta, where the Red Deer River crosses the flat prairie and farmland, and features deep canyons and striking landforms. Dinosaur Provincial Park, near Brooks, Alberta, showcases the badlands terrain, desert flora, and remnants from Alberta's past when dinosaurs roamed the then lush landscape. === Climate === Alberta has a humid continental climate with warm summers and cold winters. The province is open to cold arctic weather systems from the north, which often produce extremely cold conditions in winter. As the fronts between the air masses shift north and south across Alberta, the temperature can change rapidly. Arctic air masses in the winter produce extreme minimum temperatures varying from −54 °C (−65 °F) in northern Alberta to −46 °C (−51 °F) in southern Alberta, although temperatures at these extremes are rare. In the summer, continental air masses have produced record maximum temperatures from 32 °C (90 °F) in the mountains to over 40 °C (104 °F) in southeastern Alberta. Alberta extends for over 1,200 km (750 mi) from north to south; its climate, therefore, varies considerably. Average high temperatures in January range from 0 °C (32 °F) in the southwest to −24 °C (−11 °F) in the far north. The climate is also influenced by the presence of the Rocky Mountains to the southwest, which disrupt the flow of the prevailing westerly winds and cause them to drop most of their moisture on the western slopes of the mountain ranges before reaching the province, casting a rain shadow over much of Alberta. The northerly location and isolation from the weather systems of the Pacific Ocean cause Alberta to have a dry climate with little moderation from the ocean. Annual precipitation ranges from 300 mm (12 in) in the southeast to 450 mm (18 in) in the north, except in the foothills of the Rocky Mountains where total precipitation including snowfall can reach 600 mm (24 in) annually.The province is the namesake of the Alberta clipper, a type of intense, fast-moving winter storm that generally forms over or near the province and pushed with great speed by the continental polar jetstream descends over the rest of Southern Canada and the northern tier of the United States. In the summer, the average daytime temperatures range from around 21 °C (70 °F) in the Rocky Mountain valleys and far north, up to around 28 °C (82 °F) in the dry prairie of the southeast. The northern and western parts of the province experience higher rainfall and lower evaporation rates caused by cooler summer temperatures. The south and east-central portions are prone to drought-like conditions sometimes persisting for several years, although even these areas can receive heavy precipitation, sometimes resulting in flooding. Alberta is a sunny province. Annual bright sunshine totals range between 1,900 up to just under 2,600 hours per year. Northern Alberta gets about 18 hours of daylight in the summer.In southwestern Alberta, the cold winters are frequently interrupted by warm, dry chinook winds blowing from the mountains, which can propel temperatures upward from frigid conditions to well above the freezing point in a very short period. During one chinook recorded at Pincher Creek, temperatures soared from −19 to 22 °C (−2.2 to 72 °F) in just one hour. The region around Lethbridge has the most chinooks, averaging 30 to 35 chinook days per year. Calgary has a 56% chance of a white Christmas, while Edmonton has an 86% chance.Northern Alberta is mostly covered by boreal forest and has a subarctic climate. The agricultural area of southern Alberta has a semi-arid steppe climate because the annual precipitation is less than the water that evaporates or is used by plants. The southeastern corner of Alberta, part of the Palliser Triangle, experiences greater summer heat and lower rainfall than the rest of the province, and as a result suffers frequent crop yield problems and occasional severe droughts. Western Alberta is protected by the mountains and enjoys the mild temperatures brought by winter chinook winds. Central and parts of northwestern Alberta in the Peace River region are largely aspen parkland, a biome transitional between prairie to the south and boreal forest to the north. After Saskatchewan, Alberta experiences the most tornadoes in Canada with an average of 15 verified per year. Thunderstorms, some of them severe, are frequent in the summer, especially in central and southern Alberta. The region surrounding the Calgary–Edmonton Corridor is notable for having the highest frequency of hail in Canada, which is caused by orographic lifting from the nearby Rocky Mountains, enhancing the updraft/downdraft cycle necessary for the formation of hail. === Ecology === ==== Flora ==== In central and northern Alberta the arrival of spring is marked by the early flowering of the prairie crocus anemone; this member of the buttercup family has been recorded flowering as early as March, though April is the usual month for the general population. Other prairie flora known to flower early are the golden bean and wild rose. Members of the sunflower family blossom on the prairie in the summer months between July and September. The southern and east central parts of Alberta are covered by short prairie grass, which dries up as summer lengthens, to be replaced by hardy perennials such as the prairie coneflower, fleabane, and sage. Both yellow and white sweet clover can be found throughout the southern and central areas of the province. The trees in the parkland region of the province grow in clumps and belts on the hillsides. These are largely deciduous, typically aspen, poplar, and willow. Many species of willow and other shrubs grow in virtually any terrain. On the north side of the North Saskatchewan River evergreen forests prevail for thousands of square kilometres. Aspen poplar, balsam poplar (or in some parts cottonwood), and paper birch are the primary large deciduous species. Conifers include jack pine, Rocky Mountain pine, lodgepole pine, both white and black spruce, and the deciduous conifer tamarack. ==== Fauna ==== The four climatic regions (alpine, boreal forest, parkland, and prairie) of Alberta are home to many different species of animals. The south and central prairie was the land of the bison, commonly known as buffalo, its grasses providing pasture and breeding ground for millions of buffalo. The buffalo population was decimated during early settlement, but since then buffalo have made a comeback, living on farms and in parks all over Alberta. Alberta is home to many large carnivores. Among them are the grizzly and black bears, which are found in the mountains and wooded regions. Smaller carnivores of the canine and feline families include coyotes, wolves, fox, lynx, bobcat and mountain lion (cougar). Herbivorous animals are found throughout the province. Moose, mule deer, elk, and white-tailed deer are found in the wooded regions, and pronghorn can be found in the prairies of southern Alberta. Bighorn sheep and mountain goats live in the Rocky Mountains. Rabbits, porcupines, skunks, squirrels and many species of rodents and reptiles live in every corner of the province. Alberta is home to only one variety of venomous snake, the prairie rattlesnake. Central and northern Alberta and the region farther north is the nesting ground of many migratory birds. Vast numbers of ducks, geese, swans and pelicans arrive in Alberta every spring and nest on or near one of the hundreds of small lakes that dot northern Alberta. Eagles, hawks, owls and crows are plentiful, and a huge variety of smaller seed and insect-eating birds can be found. Alberta, like other temperate regions, is home to mosquitoes, flies, wasps, and bees. Rivers and lakes are populated with pike, walleye, whitefish, rainbow, speckled, brown trout, and sturgeon. Bull trout, native to the province, is Alberta's provincial fish. Turtles are found in some water bodies in the southern part of the province. Frogs and salamanders are a few of the amphibians that make their homes in Alberta. Alberta is the only province in Canada—as well as one of the few places in the world—that is free of Norwegian rats. Since the early 1950s, the Government of Alberta has operated a rat-control program, which has been so successful that only isolated instances of wild rat sightings are reported, usually of rats arriving in the province aboard trucks or by rail. In 2006, Alberta Agriculture reported zero findings of wild rats; the only rat interceptions have been domesticated rats that have been seized from their owners. It is illegal for individual Albertans to own or keep Norwegian rats of any description; the animals can only be kept in the province by zoos, universities and colleges, and recognized research institutions. In 2009, several rats were found and captured, in small pockets in southern Alberta, putting Alberta's rat-free status in jeopardy. A colony of rats were subsequently found in a landfill near Medicine Hat in 2012, and again in 2014. === Paleontology === Alberta has one of the greatest diversities and abundances of Late Cretaceous dinosaur fossils in the world. Taxa are represented by complete fossil skeletons, isolated material, microvertebrate remains, and even mass graves. At least 38 dinosaur type specimens were collected in the province. The Foremost Formation, Oldman Formation and Dinosaur Park Formations collectively comprise the Judith River Group and are the most thoroughly studied dinosaur-bearing strata in Alberta.Dinosaur-bearing strata are distributed widely throughout Alberta. The Dinosaur Provincial Park area contains outcrops of the Dinosaur Park Formation and Oldman Formation. In the central and southern regions of Alberta are intermittent Scollard Formation outcrops. In the Drumheller Valley and Edmonton regions there are exposed Horseshoe Canyon facies. Other formations have been recorded as well, like the Milk River and Foremost Formations. However, these latter two have a lower diversity of documented dinosaurs, primarily due to their lower total fossil quantity and neglect from collectors who are hindered by the isolation and scarcity of exposed outcrops. Their dinosaur fossils are primarily teeth recovered from microvertebrate fossil sites. Additional geologic formations that have produced only few fossils are the Belly River Group and St. Mary River Formations of the southwest and the northwestern Wapiti Formation. The Wapiti Formation contains two Pachyrhinosaurus bone beds that break its general trend of low productivity, however. The Bearpaw Formation represents strata deposited during a marine transgression. Dinosaurs are known from this formation, but represent specimens washed out to sea or reworked from older sediments. == History == Paleo-Indians arrived in Alberta at least 10,000 years ago, toward the end of the last ice age. They are thought to have migrated from Siberia to Alaska on a land bridge across the Bering Strait and then possibly moved down the east side of the Rocky Mountains through Alberta to settle the Americas. Others may have migrated down the coast of British Columbia and then moved inland. Over time they differentiated into various First Nations peoples, including the Plains Indian tribes of southern Alberta such as those of the Blackfoot Confederacy and the Plains Cree, who generally lived by hunting buffalo, and the more northerly tribes such as the Woodland Cree and Chipewyan who hunted, trapped, and fished for a living.After the British arrival in Canada, approximately half of the province of Alberta, south of the Athabasca River drainage, became part of Rupert's Land which consisted of all land drained by rivers flowing into Hudson Bay. This area was granted by Charles II of England to the Hudson's Bay Company (HBC) in 1670, and rival fur trading companies were not allowed to trade in it. After the arrival of French Canadians in the west around 1731, they settled near fur trading posts, establishing communities such as Lac La Biche and Bonnyville. Fort La Jonquière was established near what is now Calgary in 1752. The Athabasca River and the rivers north of it were not in HBC territory because they drained into the Arctic Ocean instead of Hudson Bay, and they were prime habitat for fur-bearing animals. The first explorer of the Athabasca region was Peter Pond, who learned of the Methye Portage, which allowed travel from southern rivers into the rivers north of Rupert's Land. Fur traders formed the North West Company (NWC) of Montreal to compete with the HBC in 1779. The NWC occupied the northern part of Alberta territory. Peter Pond built Fort Athabasca on Lac la Biche in 1778. Roderick Mackenzie built Fort Chipewyan on Lake Athabasca ten years later in 1788. His cousin, Sir Alexander Mackenzie, followed the North Saskatchewan River to its northernmost point near Edmonton, then setting northward on foot, trekked to the Athabasca River, which he followed to Lake Athabasca. It was there he discovered the mighty outflow river which bears his name—the Mackenzie River—which he followed to its outlet in the Arctic Ocean. Returning to Lake Athabasca, he followed the Peace River upstream, eventually reaching the Pacific Ocean, and so he became the first European to cross the North American continent north of Mexico.The extreme southernmost portion of Alberta was part of the French (and Spanish) territory of Louisiana, sold to the United States in 1803; in 1818, the portion of Louisiana north of the Forty-Ninth Parallel was ceded to Great Britain.Fur trade expanded in the north, but bloody battles occurred between the rival HBC and NWC, and in 1821 the British government forced them to merge to stop the hostilities. The amalgamated Hudson's Bay Company dominated trade in Alberta until 1870, when the newly formed Canadian Government purchased Rupert's Land. Northern Alberta was included in the North-Western Territory until 1870, when it and Rupert's land became Canada's Northwest Territories. The District of Alberta was created as part of the North-West Territories in 1882. As settlement increased, local representatives to the North-West Legislative Assembly were added. After a long campaign for autonomy, in 1905 the District of Alberta was enlarged and given provincial status, with the election of Alexander Cameron Rutherford as the first premier. Less than a decade later, the First World War presented special challenges to the new province as an extraordinary number of volunteers left relatively few workers to maintain services and production. Over 50% of Alberta's doctors volunteered for service overseas.On June 21, 2013, during the 2013 Alberta floods Alberta experienced heavy rainfall that triggered catastrophic flooding throughout much of the southern half of the province along the Bow, Elbow, Highwood and Oldman rivers and tributaries. A dozen municipalities in Southern Alberta declared local states of emergency on June 21 as water levels rose and numerous communities were placed under evacuation orders.In 2016, a wildfire resulted in the largest evacuation of residents in Alberta's history, as more than 80,000 people were ordered to evacuate. == Demographics == The 2016 census reported Alberta had a population of 4,067,175 living in 1,527,678 of its 1,654,129 total dwellings, an 11.6% change from its 2011 population of 3,645,257. With a land area of 640,330.46 km2 (247,232.97 sq mi), it had a population density of 6.4/km2 (16.5/sq mi) in 2016. Statistics Canada estimated the province to have a population of 4,280,127 in Q1 of 2017.Since 2000, Alberta's population has experienced a relatively high rate of growth, mainly because of its burgeoning economy. Between 2003 and 2004, the province had high birthrates (on par with some larger provinces such as British Columbia), relatively high immigration, and a high rate of interprovincial migration compared to other provinces. In 2016, Alberta continued to have the youngest population among the provinces with a median age of 36.7 years, compared with the national median of 41.2 years. Also in 2016, Alberta had the smallest proportion of seniors (12.3%) among the provinces and one of the highest population shares of children (19.2%), further contributing to Alberta's young and growing population.About 81% of the population lives in urban areas and only about 19% in rural areas. The Calgary–Edmonton Corridor is the most urbanized area in the province and is one of the most densely populated areas of Canada. Many of Alberta's cities and towns have experienced very high rates of growth in recent history. Alberta's population rose from 73,022 in 1901 to 3,290,350 according to the 2006 census. The 2006 census found that English, with 2,576,670 native speakers, was the most common mother tongue of Albertans, representing 79.99% of the population. The next most common mother tongues were Chinese with 97,275 native speakers (3.02%), followed by German with 84,505 native speakers (2.62%) and French with 61,225 (1.90%).Other mother tongues include: Punjabi, with 36,320 native speakers (1.13%); Tagalog, with 29,740 (0.92%); Ukrainian, with 29,455 (0.91%); Spanish, with 29,125 (0.90%); Polish, with 21,990 (0.68%); Arabic, with 20,495 (0.64%); Dutch, with 19,980 (0.62%); and Vietnamese, with 19,350 (0.60%). The most common aboriginal language is Cree 17,215 (0.53%). Other common mother tongues include Italian with 13,095 speakers (0.41%); Urdu with 11,275 (0.35%); and Korean with 10,845 (0.33%); then Hindi 8,985 (0.28%); Persian 7,700 (0.24%); Portuguese 7,205 (0.22%); and Hungarian 6,770 (0.21%).(Figures shown are for the number of single language responses and the percentage of total single-language responses.) Alberta has considerable ethnic diversity. In line with the rest of Canada, many immigrants originated from England, Scotland, Ireland, Wales and France, but large numbers also came from other parts of Europe, notably Germany, Ukraine and Scandinavia. According to Statistics Canada, Alberta is home to the second-highest proportion (two percent) of Francophones in western Canada (after Manitoba). Despite this, relatively few Albertans claim French as their mother tongue. Many of Alberta's French-speaking residents live in the central and northwestern regions of the province. As reported in the 2001 census, the Chinese represented nearly four percent of Alberta's population, and East Indians represented more than two percent. Both Edmonton and Calgary have historic Chinatowns, and Calgary has Canada's third-largest Chinese community. The Chinese presence began with workers employed in the building of the Canadian Pacific Railway in the 1880s. Aboriginal Albertans make up approximately three percent of the population. In the 2006 Canadian census, the most commonly reported ethnic origins among Albertans were: 885,825 English (27.2%); 679,705 German (20.9%); 667,405 Canadian (20.5%); 661,265 Scottish (20.3%); 539,160 Irish (16.6%); 388,210 French (11.9%); 332,180 Ukrainian (10.2%); 172,910 Dutch (5.3%); 170,935 Polish (5.2%); 169,355 North American Indian (5.2%); 144,585 Norwegian (4.4%); and 137,600 Chinese (4.2%). (Each person could choose as many ethnicities as were applicable.)Amongst those of British origins, the Scots have had a particularly strong influence on place-names, with the names of many cities and towns including Calgary, Airdrie, Canmore, and Banff having Scottish origins. Alberta is the third most diverse province in terms of visible minorities after British Columbia and Ontario with 13.9% of the population consisting of visible minorities. Over one third of the populations of Calgary and Edmonton belong to a visible minority group.Aboriginal Identity Peoples make up 5.8% of the population, about half of whom consist of North American Indians and the other half are Metis. There are also small number of Inuit people in Alberta. The number of Aboriginal Identity Peoples have been increasing at a rate greater than the population of Alberta. As of the 2011 National Household Survey, the largest religious group was Roman Catholic, representing 24.3% of the population. Alberta had the second-highest percentage of non-religious residents among the provinces (after British Columbia) at 31.6% of the population. Of the remainder, 7.5% of the population identified themselves as belonging to the United Church of Canada, while 3.9% were Anglican. Lutherans made up 3.3% of the population while Baptists comprised 1.9%.The remainder belonged to a wide variety of different religious affiliations, none of which constituted more than 2% of the population. Members of LDS Church are mostly concentrated in the extreme south of the province. Alberta has a population of Hutterites, a communal Anabaptist sect similar to the Mennonites, and has a significant population of Seventh-day Adventists. Alberta is home to several Byzantine Rite Churches as part of the legacy of Eastern European immigration, including the Ukrainian Catholic Eparchy of Edmonton, and the Ukrainian Orthodox Church of Canada's Western Diocese which is based in Edmonton. Muslims, Sikhs, Buddhists, and Hindus live in Alberta. Muslims made up 3.2% of the population, Sikhs 1.5%, Buddhists 1.2%, and Hindus 1.0%. Many of these are recent immigrants, but others have roots that go back to the first settlers of the prairies. Canada's oldest mosque, the Al-Rashid Mosque, is located in Edmonton, whereas Calgary is home to Canada's largest mosque, the Baitun Nur Mosque. Alberta is also home to a growing Jewish population of about 15,400 people who constituted 0.3% of Alberta's population. Most of Alberta's Jews live in the metropolitan areas of Calgary (8,200) and Edmonton (5,500). === Municipalities === Largest metro areas and municipalities by population as of 2006 == Economy == Alberta's economy was one of the strongest in the world, supported by the burgeoning petroleum industry and to a lesser extent, agriculture and technology. In 2013 Alberta's per capita GDP exceeded that of the United States, Norway, or Switzerland, and was the highest of any province in Canada at C$84,390. This was 56% higher than the national average of C$53,870 and more than twice that of some of the Atlantic provinces. In 2006 the deviation from the national average was the largest for any province in Canadian history. According to the 2006 census, the median annual family income after taxes was $70,986 in Alberta (compared to $60,270 in Canada as a whole). In 2014, Alberta had the second-largest economy in Canada after Ontario, with a GDP exceeding C$376 billion.Alberta's debt-to-GDP ratio is projected to reach 11.4% in fiscal year 2019–2020, compared to a surplus-to-GDP ratio of 13.4% in 2009–2010.The Calgary-Edmonton Corridor is the most urbanized region in the province and one of the densest in Canada. The region covers a distance of roughly 400 kilometres north to south. In 2001, the population of the Calgary-Edmonton Corridor was 2.15 million (72% of Alberta's population). It is also one of the fastest-growing regions in the country. A 2003 study by TD Bank Financial Group found the corridor to be the only Canadian urban centre to amass a U.S. level of wealth while maintaining a Canadian style quality of life, offering universal health care benefits. The study found that GDP per capita in the corridor was 10% above average U.S. metropolitan areas and 40% above other Canadian cities at that time. The Fraser Institute states that Alberta also has very high levels of economic freedom and rates Alberta as the freest economy in Canada, and second-freest economy amongst U.S. states and Canadian provinces. The government of Alberta has invested its earnings wisely; as of September 30, 2013, official statistics reported nearly 500 holdings.In 2014, Merchandise exports totalled US$121.4 billion. Energy revenues totalled $111.7 billion and Energy resource exports totalled $90.8 billion. Farm Cash receipts from agricultural products totalled $12.9 billion. Shipments of forest products totalled $5.4 billion while exports were $2.7 billion. Manufacturing sales totaled $79.4 billion, and Alberta's ICT industries generated over $13 billion in revenue. In total, Alberta's 2014 GDP amassed $364.5 billion in 2007 dollars, or $414.3 billion in 2015 dollars. In 2015, Alberta's GDP grew despite low oil prices; however, it was unstable with growth rates as high 4.4% and as low as 0.2%. Should the GDP remain at an average of 2.2% for the last two quarters of 2015, Alberta's GDP should exceed $430 billion by the end of 2015. However, RBC Economics research predicts Alberta's real GDP growth to only average 0.6% for the last two quarters of 2015. This estimate predicts a real GDP growth of only 1.4% for 2015. A positive is the predicted 10.8% growth in Nominal GDP, and possibly above 11% in 2016. === Industry === Alberta is the largest producer of conventional crude oil, synthetic crude, natural gas and gas products in Canada. Alberta is the world's second-largest exporter of natural gas and the fourth-largest producer. Two of the largest producers of petrochemicals in North America are located in central and north-central Alberta. In both Red Deer and Edmonton, polyethylene and vinyl manufacturers produce products that are shipped all over the world. Edmonton's oil refineries provide the raw materials for a large petrochemical industry to the east of Edmonton. The Athabasca oil sands surrounding Fort McMurray have estimated unconventional oil reserves approximately equal to the conventional oil reserves of the rest of the world, estimated to be 1.6 trillion barrels (254 km3). Many companies employ both conventional strip mining and non-conventional in situ methods to extract the bitumen from the oil sands. As of late 2006 there were over $100 billion in oil sands projects under construction or in the planning stages in northeastern Alberta.Another factor determining the viability of oil extraction from the oil sands is the price of oil. The oil price increases since 2003 have made it profitable to extract this oil, which in the past would give little profit or even a loss. By mid-2014, however, rising costs and stabilizing oil prices were threatening the economic viability of some projects. An example of this was the shelving of the Joslyn north project in the Athabasca region in May 2014.With concerted effort and support from the provincial government, several high-tech industries have found their birth in Alberta, notably patents related to interactive liquid-crystal display systems. With a growing economy, Alberta has several financial institutions dealing with civil and private funds. === Agriculture and forestry === Agriculture has a significant position in the province's economy. The province has over three million head of cattle, and Alberta beef has a healthy worldwide market. Nearly one half of all Canadian beef is produced in Alberta. Alberta is one of the top producers of plains buffalo (bison) for the consumer market. Sheep for wool and mutton are also raised. Wheat and canola are primary farm crops, with Alberta leading the provinces in spring wheat production; other grains are also prominent. Much of the farming is dryland farming, often with fallow seasons interspersed with cultivation. Continuous cropping (in which there is no fallow season) is gradually becoming a more common mode of production because of increased profits and a reduction of soil erosion. Across the province, the once common grain elevator is slowly being lost as rail lines are decreasing; farmers typically truck the grain to central points.Alberta is the leading beekeeping province of Canada, with some beekeepers wintering hives indoors in specially designed barns in southern Alberta, then migrating north during the summer into the Peace River valley where the season is short but the working days are long for honeybees to produce honey from clover and fireweed. Hybrid canola also requires bee pollination, and some beekeepers service this need.Forestry plays a vital role in Alberta's economy, providing over 15,000 jobs and contributing billions of dollars annually. Uses for harvested timber include pulpwood, hardwood, engineered wood and bioproducts such as chemicals and biofuels. Recently, the United States has been Canada and Alberta's largest importer of hardwood and pulpwood, although continued trades issues with the U.S. have likely been a contributing factor towards Alberta's increased focus on Asian markets. === Tourism === Alberta has been a tourist destination from the early days of the twentieth century, with attractions including outdoor locales for skiing, hiking and camping, shopping locales such as West Edmonton Mall, Calgary Stampede, outdoor festivals, professional athletic events, international sporting competitions such as the Commonwealth Games and Olympic Games, as well as more eclectic attractions. There are also natural attractions like Elk Island National Park, Wood Buffalo National Park, and the Columbia Icefield. According to Alberta Economic Development, Calgary and Edmonton both host over four million visitors annually. Banff, Jasper and the Rocky Mountains are visited by about three million people per year. Alberta tourism relies heavily on Southern Ontario tourists, as well as tourists from other parts of Canada, the United States, and many other countries. Alberta's Rockies include well-known tourist destinations Banff National Park and Jasper National Park. The two mountain parks are connected by the scenic Icefields Parkway. Banff is located 128 km (80 mi) west of Calgary on Highway 1, and Jasper is located 366 km (227 mi) west of Edmonton on Yellowhead Highway. Five of Canada's fourteen UNESCO World heritage sites are located within the province: Canadian Rocky Mountain Parks, Waterton-Glacier International Peace Park, Wood Buffalo National Park, Dinosaur Provincial Park and Head-Smashed-In Buffalo Jump. About 1.2 million people visit the Calgary Stampede, a celebration of Canada's own Wild West and the cattle ranching industry. About 700,000 people enjoy Edmonton's K-Days (formerly Klondike Days and Capital EX). Edmonton was the gateway to the only all-Canadian route to the Yukon gold fields, and the only route which did not require gold-seekers to travel the exhausting and dangerous Chilkoot Pass. Another tourist destination that draws more than 650,000 visitors each year is the Drumheller Valley, located northeast of Calgary. Drumheller, "Dinosaur Capital of The World", offers the Royal Tyrrell Museum of Palaeontology. Drumheller also had a rich mining history being one of Western Canada's largest coal producers during the war years. Located in east-central Alberta is Alberta Prairie Railway Excursions, a popular tourist attraction operated out of Stettler, that offers train excursions into the prairie and caters to tens of thousands of visitors every year. Alberta has numerous ski resorts most notably Sunshine Village, Lake Louise, Marmot Basin, Norquay and Nakiska. == Government and politics == The Government of Alberta is organized as a parliamentary democracy with a unicameral legislature. Its unicameral legislature—the Legislative Assembly—consists of eighty-seven members elected first past the post (FPTP) from single-member constituencies.Locally municipal governments and school boards are elected and operate separately. Their boundaries do not necessarily coincide. As Canada's head of state, Queen Elizabeth II is the head of state for the Government of Alberta. Her duties in Alberta are carried out by Lieutenant Governor Lois Mitchell. The Queen and lieutenant governor are figureheads whose actions are highly restricted by custom and constitutional convention. The lieutenant governor handles numerous honorific duties in the name of the Queen. The government is headed by the premier. The premier is normally a member of the Legislative Assembly, and draws all the members of the Cabinet from among the members of the Legislative Assembly. The City of Edmonton is the seat of the provincial government—the capital of Alberta. The current premier is Rachel Notley, sworn in on May 24, 2015. The previous premier was Jim Prentice, who became the leader of the then governing Progressive Conservatives on September 6, 2014, following the resignation of Alison Redford and the interim leadership of Dave Hancock. Prentice was sworn in as the 16th Premier of Alberta on September 15, 2014. He called an early election on May 5, 2015 in which the opposition New Democratic Party (NDP) won a majority of the seats. Prentice immediately resigned his seat and leadership of the PC party, but remained premier until Notley was sworn in on May 24, 2015. Alberta's elections have tended to yield much more conservative outcomes than those of other Canadian provinces. Since the 1960s, Alberta has had three main political parties, the Progressive Conservatives ("Conservatives" or "Tories"), the Liberals, and the social democratic New Democrats. The Wildrose Party, a more conservative party formed in early 2008, gained much support in 2012 election and became the official opposition, a role it held until 2017 when it was dissolved and succeeded by the new United Conservative Party created by the merger of Wildrose and Progressive Conservatives. The strongly conservative Social Credit Party was a power in Alberta for many decades, but fell from the political map after the Progressive Conservatives came to power in 1971. For 44 years the Progressive Conservatives governed Alberta. They lost the 2015 election to the NDP, signalling a possible shift to the left in the province, also indicated by the election of progressive mayors in both of Alberta's major cities. Since becoming a province in 1905, Alberta has seen only four changes of government—only five parties have governed Alberta: the Liberals, from 1905 to 1921; the United Farmers of Alberta, from 1921 to 1935; the Social Credit Party, from 1935 to 1971, the Progressive Conservative Party, from 1971 to 2015: and the currently governing Alberta New Democratic Party. Alberta has had occasional surges in separatist sentiment. Even during the 1980s, when these feelings were at their strongest, there has not been enough interest in secession to initiate any major movement or referendum. Several groups are currently active promoting independence for Alberta in some form. === Taxation === Government revenue comes mainly from royalties on non-renewable natural resources (30.4%), personal income taxes (22.3%), corporate and other taxes (19.6%), and grants from the federal government primarily for infrastructure projects (9.8%). Albertans are the lowest-taxed people in Canada, and Alberta is the only province in Canada without a provincial sales tax (but residents are still subject to the federal sales tax, the Goods and Services Tax of 5%). It is also the only Canadian province to have a flat tax for personal income taxes, which is 10% of taxable income.The Alberta personal income tax system maintains a progressive character by granting residents personal tax exemptions of $17,787, in addition to a variety of tax deductions for persons with disabilities, students, and the aged. Alberta's municipalities and school jurisdictions have their own governments who usually work in co-operation with the provincial government. Alberta also privatized alcohol distribution. The privatization increased outlets from 304 stores to 1,726; 1,300 jobs to 4,000 jobs; and 3,325 products to 16,495 products. Tax revenue also increased from $400 million to $700 million. Albertan municipalities raise a significant portion of their income through levying property taxes. The value of assessed property in Alberta was approximately $727 billion in 2011. Most real property is assessed according to its market value. The exceptions to market value assessment are farmland, railways, machinery & equipment and linear property, all of which is assessed by regulated rates. Depending on the property type, property owners may appeal a property assessment to their municipal 'Local Assessment Review Board', 'Composite Assessment Review Board,' or the Alberta Municipal Government Board. === Law enforcement === Policing in the province of Alberta upon its creation was the responsibility of the Royal Northwest Mounted Police. In 1917, due to pressures of World War I, the Alberta Provincial Police was created. This organization policed the province until it was disbanded as a Great Depression era cost cutting measure in 1932. It was at that time the now renamed Royal Canadian Mounted Police resumed policing of the province, specifically RCMP "K" Division. With the advent of the Alberta Sheriffs Branch, the duties of law enforcement in Alberta has been evolving as certain aspects, such as traffic enforcement, mobile surveillance and the close protection of the Premier of Alberta have been transferred to the Sheriffs. In 2006, Alberta formed the Alberta Law Enforcement Response Teams (ALERT) to combat organized crime and the serious offences that accompany it. ALERT is made up of members of the RCMP, Sheriffs Branch and various major municipal police forces in Alberta. === Military === Military bases in Alberta include Canadian Forces Base (CFB) Cold Lake, CFB Edmonton, CFB Suffield and CFB Wainwright. Air force units stationed at CFB Cold Lake have access to the Cold Lake Air Weapons Range. CFB Edmonton is the headquarters for the 3rd Canadian Division. CFB Suffield hosts British troops and is the largest training facility in Canada. == Transportation == === Road === Alberta has over 181,000 km (112,000 mi) of highways and roads, of which nearly 41,000 km (25,000 mi) are paved. The main north-south corridor is Highway 2, which begins south of Cardston at the Carway border crossing and is part of the CANAMEX Corridor. Highway 4, which effectively extends Interstate 15 into Alberta and is the busiest U.S. gateway to the province, begins at the Coutts border crossing and ends at Lethbridge. Highway 3 joins Lethbridge to Fort Macleod and links Highway 2 to Highway 4. Highway 2 travels north through Fort Macleod, Calgary, Red Deer, and Edmonton.North of Edmonton, the highway continues to Athabasca, then northwesterly along the south shore of Lesser Slave Lake into High Prairie, north to Peace River, west to Fairview and finally south to Grande Prairie, where it ends at an interchange with Highway 43. The section of Highway 2 between Calgary and Edmonton has been named the Queen Elizabeth II Highway to commemorate the visit of the monarch in 2005. Highway 2 is supplemented by two more highways that run parallel to it: Highway 22, west of Highway 2, known as Cowboy Trail, and Highway 21, east of Highway 2. Highway 43 travels northwest into Grande Prairie and the Peace River Country; Highway 63 travels northeast to Fort McMurray, the location of the Athabasca oil sands.Alberta has two main east-west corridors. The southern corridor, part of the Trans-Canada Highway system, enters the province near Medicine Hat, runs westward through Calgary, and leaves Alberta through Banff National Park. The northern corridor, also part of the Trans-Canada network and known as the Yellowhead Highway (Highway 16), runs west from Lloydminster in eastern Alberta, through Edmonton and Jasper National Park into British Columbia. One of the most scenic drives is along the Icefields Parkway, which runs for 228 km (142 mi) between Jasper and Lake Louise, with mountain ranges and glaciers on either side of its entire length. A third corridor stretches across southern Alberta; Highway 3 runs between Crowsnest Pass and Medicine Hat through Lethbridge and forms the eastern portion of the Crowsnest Highway. Another major corridor through central Alberta is Highway 11 (also known as the David Thompson Highway), which runs east from the Saskatchewan River Crossing in Banff National Park through Rocky Mountain House and Red Deer, connecting with Highway 12 20 km (12 mi) west of Stettler. The highway connects many of the smaller towns in central Alberta with Calgary and Edmonton, as it crosses Highway 2 just west of Red Deer.Urban stretches of Alberta's major highways and freeways are often called trails. For example, Highway 2, the main north-south highway in the province, is called Deerfoot Trail as it passes through Calgary but becomes Calgary Trail (for southbound traffic) and Gateway Boulevard (for northbound traffic) as it enters Edmonton and then turns into St. Albert Trail as it leaves Edmonton for the City of St. Albert. Calgary, in particular, has a tradition of calling its largest urban expressways trails and naming many of them after prominent First Nations individuals and tribes, such as Crowchild Trail, Deerfoot Trail, and Stoney Trail. === Public transit === Calgary, Edmonton, Red Deer, Medicine Hat, and Lethbridge have substantial public transit systems. In addition to buses, Calgary and Edmonton operate light rail transit (LRT) systems. Edmonton LRT, which is underground in the downtown core and on the surface outside the CBD, was the first of the modern generation of light rail systems to be built in North America, while the Calgary C-Train has one of the highest number of daily riders of any LRT system in North America. === Air === Alberta is well-connected by air, with international airports in both Calgary and Edmonton. Calgary International Airport and Edmonton International Airport are the third- and fifth-busiest in Canada, respectively. Calgary's airport is a hub for WestJet Airlines and a regional hub for Air Canada. Calgary's airport primarily serves the Canadian prairie provinces (Alberta, Saskatchewan and Manitoba) for connecting flights to British Columbia, eastern Canada, 15 major U.S. centres, nine European airports, one Asian airport and four destinations in Mexico and the Caribbean. Edmonton's airport acts as a hub for the Canadian north and has connections to all major Canadian airports as well as 10 major U.S. airports, 3 European airports and 6 Mexican and Caribbean airports. === Rail === There are more than 9,000 km (5,600 mi) of operating mainline railway in Alberta. The vast majority of this trackage is owned by the Canadian Pacific Railway and Canadian National Railway companies, which operate railway freight across the province. Additional railfreight service in the province is provided by two shortline railways: the Battle River Railway and Forty Mile Rail. Passenger trains include Via Rail's Canadian (Toronto–Vancouver) or Jasper–Prince Rupert trains, which use the CN mainline and pass through Jasper National Park and parallel the Yellowhead Highway during at least part of their routes. The Rocky Mountaineer operates two sections: one from Vancouver to Banff and Calgary over CP tracks, and a section that travels over CN tracks to Jasper. == Health care == Alberta provides a publicly funded health care system, Alberta Health Services, for all its citizens and residents as set out by the provisions of the Canada Health Act of 1984. Alberta became Canada's second province (after Saskatchewan) to adopt a Tommy Douglas-style program in 1950, a precursor to the modern medicare system. Alberta's health care budget is currently $22.5 billion during the 2018–2019 fiscal year (approximately 45% of all government spending), making it the best funded health care system per-capita in Canada. Every hour the province spends more than $2.5 million, (or $60 million per day), to maintain and improve health care in the province. Notable health, education, research, and resources facilities in Alberta, all of which are located within Calgary or Edmonton: The Edmonton Clinic complex, completed in 2012, provides a similar research, education, and care environment as the Mayo Clinic in the United States.All public health care services funded by the Government of Alberta are delivered operationally by Alberta Health Services. AHS is the province's single health authority established on July 1, 2008, which replaced nine local health authorities. AHS also funds all ground ambulance services in the province, as well as the province-wide STARS (Shock Trauma Air Rescue Society) air ambulance service. == Education == As with any Canadian province, the Alberta Legislature has (almost) exclusive authority to make laws respecting education. Since 1905 the Legislature has used this capacity to continue the model of locally elected public and separate school boards which originated prior to 1905, as well as to create and regulate universities, colleges, technical institutions and other educational forms and institutions (public charter schools, private schools, home schooling). === Elementary schools === There are forty-two public school jurisdictions in Alberta, and seventeen operating separate school jurisdictions. Sixteen of the operating separate school jurisdictions have a Catholic electorate, and one (St. Albert) has a Protestant electorate. In addition, one Protestant separate school district, Glen Avon, survives as a ward of the St. Paul Education Region. The City of Lloydminster straddles the Alberta/Saskatchewan border, and both the public and separate school systems in that city are counted in the above numbers: both of them operate according to Saskatchewan law. For many years the provincial government has funded the greater part of the cost of providing K–12 education. Prior to 1994 public and separate school boards in Alberta had the legislative authority to levy a local tax on property as a supplementary support for local education. In 1994 the government of the province eliminated this right for public school boards, but not for separate school boards. Since 1994 there has continued to be a tax on property in support of K–12 education; the difference is that the mill rate is now set by the provincial government, the money is collected by the local municipal authority and remitted to the provincial government. The relevant legislation requires that all the money raised by this property tax must go to the support of K–12 education provided by school boards. The provincial government pools the property tax funds from across the province and distributes them, according to a formula, to public and separate school jurisdictions and Francophone authorities. Public and separate school boards, charter schools, and private schools all follow the Program of Studies and the curriculum approved by the provincial department of education (Alberta Education). Homeschool tutors may choose to follow the Program of Studies or develop their own Program of Studies. Public and separate schools, charter schools, and approved private schools all employ teachers who are certificated by Alberta Education, they administer Provincial Achievement Tests and Diploma Examinations set by Alberta Education, and they may grant high school graduation certificates endorsed by Alberta Education. === Universities === The University of Alberta, located in Edmonton and established in 1908, is Alberta's oldest and largest university. The University of Calgary, once affiliated with the University of Alberta, gained its autonomy in 1966 and is now the second-largest university in Alberta. Athabasca University, which focuses on distance learning, and the University of Lethbridge are located in Athabasca and Lethbridge respectively. In early September 2009, Mount Royal University became Calgary's second public university, and in late September 2009, a similar move made MacEwan University Edmonton's second public university. There are 15 colleges that receive direct public funding, along with two technical institutes, Northern Alberta Institute of Technology and Southern Alberta Institute of Technology.There is also a large and active private sector of post-secondary institutions, mostly Christian Universities, bringing the total number of universities to 12. Students may also receive government loans and grants while attending selected private institutions. There has been some controversy in recent years over the rising cost of post-secondary education for students (as opposed to taxpayers). In 2005, Premier Ralph Klein made a promise that he would freeze tuition and look into ways of reducing schooling costs. == Culture == Summer brings many festivals to the province of Alberta, especially in Edmonton. The Edmonton Fringe Festival is the world's second-largest after the Edinburgh Festival. Both Calgary and Edmonton host a number of annual festivals and events, including folk music festivals. The city's "heritage days" festival sees the participation of over 70 ethnic groups. Edmonton's Churchill Square is home to a large number of the festivals, including the large Taste of Edmonton & The Works Art & Design Festival throughout the summer months. The City of Calgary is also famous for its Stampede, dubbed "The Greatest Outdoor Show on Earth". The Stampede is Canada's biggest rodeo festival and features various races and competitions, such as calf roping and bull riding. In line with the western tradition of rodeo are the cultural artisans that reside and create unique Alberta western heritage crafts. The Banff Centre hosts a range of festivals and other events including the international Mountain Film Festival. These cultural events in Alberta highlight the province's cultural diversity. Most of the major cities have several performing theatre companies who entertain in venues as diverse as Edmonton's Arts Barns and the Francis Winspear Centre for Music. Both Calgary and Edmonton are home to Canadian Football League and National Hockey League teams. Soccer, rugby union and lacrosse are also played professionally in Alberta. == Friendship partners == Alberta has relationships with several provinces, states, and other entities worldwide. Gangwon-do, South Korea (1974) Hokkaido, Japan (1980) Heilongjiang, People's Republic of China (1981) Montana, United States (1985) Tyumen, Russia (1992) Khanty–Mansi, Russia (1995) Yamalo-Nenets, Russia (1997) Jalisco, Mexico (1999) Alaska, United States (2002) Saxony, Germany (2002) Ivano-Frankivsk, Ukraine (2004) Lviv, Ukraine (2005) California, United States (1997) == See also == Outline of Alberta Index of Alberta-related articles == References == == Further reading == == External links == Government of Alberta website Alberta at Curlie (based on DMOZ) Alberta Encyclopedia ### Answer: <Alberta>, <Canadian Prairies>, <Provinces and territories of Canada>, <States and territories established in 1905>

### Instruction: retrieve labels for this: Albert Einstein (; German: [ˈalbɛɐ̯t ˈʔaɪnʃtaɪn] ( listen); 14 March 1879 – 18 April 1955) was a German-born theoretical physicist who developed the theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics). His work is also known for its influence on the philosophy of science. He is best known to the general public for his mass–energy equivalence formula E = mc2, which has been dubbed "the world's most famous equation". He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the development of quantum theory. Near the beginning of his career, Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field. This led him to develop his special theory of relativity during his time at the Swiss Patent Office in Bern (1902–1909), Switzerland. However, he realized that the principle of relativity could also be extended to gravitational fields, and he published a paper on general relativity in 1916 with his theory of gravitation. He continued to deal with problems of statistical mechanics and quantum theory, which led to his explanations of particle theory and the motion of molecules. He also investigated the thermal properties of light which laid the foundation of the photon theory of light. In 1917, he applied the general theory of relativity to model the structure of the universe.He lived in Switzerland between 1895 and 1914, except for one year in Prague, and he received his academic diploma from the Swiss federal polytechnic school (later the Eidgenössische Technische Hochschule, ETH) in Zürich in 1900. He taught theoretical physics there between 1912 and 1914 before he left for Berlin. He acquired Swiss citizenship in 1901, which he kept for the rest of his life after being stateless for more than five years. In 1905, he was awarded a PhD by the University of Zurich. The same year, he published four groundbreaking papers during his renowned annus mirabilis (miracle year) which brought him to the notice of the academic world at the age of 26. He was visiting the United States when Adolf Hitler came to power in 1933 and he did not go back to Germany, where he had been a professor at the Berlin Academy of Sciences. He settled in the United States and became an American citizen in 1940. On the eve of World War II, he endorsed a letter to President Franklin D. Roosevelt alerting him to the potential development of "extremely powerful bombs of a new type" and recommending that the US begin similar research. This eventually led to the Manhattan Project. Einstein supported the Allied forces, but he generally denounced the idea of using nuclear fission as a weapon. He signed the Russell–Einstein Manifesto with British philosopher Bertrand Russell, which highlighted the danger of nuclear weapons. He was affiliated with the Institute for Advanced Study in Princeton, New Jersey, until his death in 1955. Einstein published more than 300 scientific papers and more than 150 non-scientific works. His intellectual achievements and originality have made the word "Einstein" synonymous with "genius". Eugene Wigner wrote of Einstein in comparison to his contemporaries that "Einstein's understanding was deeper even than Jancsi von Neumann's. His mind was both more penetrating and more original than von Neumann's. And that is a very remarkable statement." == Life and career == === Early life and education === Albert Einstein was born in Ulm, in the Kingdom of Württemberg in the German Empire, on 14 March 1879. His parents were Hermann Einstein, a salesman and engineer, and Pauline Koch. In 1880, the family moved to Munich, where Einstein's father and his uncle Jakob founded Elektrotechnische Fabrik J. Einstein & Cie, a company that manufactured electrical equipment based on direct current.The Einsteins were non-observant Ashkenazi Jews, and Albert attended a Catholic elementary school in Munich, from the age of 5, for three years. At the age of 8, he was transferred to the Luitpold Gymnasium (now known as the Albert Einstein Gymnasium), where he received advanced primary and secondary school education until he left the German Empire seven years later.In 1894, Hermann and Jakob's company lost a bid to supply the city of Munich with electrical lighting because they lacked the capital to convert their equipment from the direct current (DC) standard to the more efficient alternating current (AC) standard. The loss forced the sale of the Munich factory. In search of business, the Einstein family moved to Italy, first to Milan and a few months later to Pavia. When the family moved to Pavia, Einstein, then 15, stayed in Munich to finish his studies at the Luitpold Gymnasium. His father intended for him to pursue electrical engineering, but Einstein clashed with authorities and resented the school's regimen and teaching method. He later wrote that the spirit of learning and creative thought was lost in strict rote learning. At the end of December 1894, he travelled to Italy to join his family in Pavia, convincing the school to let him go by using a doctor's note. During his time in Italy he wrote a short essay with the title "On the Investigation of the State of the Ether in a Magnetic Field".Einstein always excelled at maths and physics from a young age, reaching a mathematical level years ahead of his peers. The twelve year old Einstein taught himself algebra and Euclidean geometry over a single summer. Einstein also independently discovered his own original proof of the Pythagorean theorem at age 12. A family tutor Max Talmud says that after he had given the 12 year old Einstein a geometry textbook, after a short time "[Einstein] had worked through the whole book. He thereupon devoted himself to higher mathematics... Soon the flight of his mathematical genius was so high I could not follow." His passion for geometry and algebra led the twelve year old to become convinced that nature could be understood as a "mathematical structure". Einstein started teaching himself calculus at 12, and as a 14 year old he says he had "mastered integral and differential calculus".At age 13, Einstein was introduced to Kant's Critique of Pure Reason, and Kant became his favorite philosopher, his tutor stating: "At the time he was still a child, only thirteen years old, yet Kant's works, incomprehensible to ordinary mortals, seemed to be clear to him."In 1895, at the age of 16, Einstein took the entrance examinations for the Swiss Federal Polytechnic in Zürich (later the Eidgenössische Technische Hochschule, ETH). He failed to reach the required standard in the general part of the examination, but obtained exceptional grades in physics and mathematics. On the advice of the principal of the Polytechnic, he attended the Argovian cantonal school (gymnasium) in Aarau, Switzerland, in 1895 and 1896 to complete his secondary schooling. While lodging with the family of professor Jost Winteler, he fell in love with Winteler's daughter, Marie. Albert's sister Maja later married Winteler's son Paul. In January 1896, with his father's approval, Einstein renounced his citizenship in the German Kingdom of Württemberg to avoid military service. In September 1896, he passed the Swiss Matura with mostly good grades, including a top grade of 6 in physics and mathematical subjects, on a scale of 1–6. At 17, he enrolled in the four-year mathematics and physics teaching diploma program at the Zürich Polytechnic. Marie Winteler, who was a year older, moved to Olsberg, Switzerland, for a teaching post. Einstein's future wife, a 20-year old Serbian woman Mileva Marić, also enrolled at the Polytechnic that year. She was the only woman among the six students in the mathematics and physics section of the teaching diploma course. Over the next few years, Einstein and Marić's friendship developed into romance, and they read books together on extra-curricular physics in which Einstein was taking an increasing interest. In 1900, Einstein passed the exams in Maths and Physics and was awarded the Federal Polytechnic teaching diploma. There have been claims that Marić collaborated with Einstein on his 1905 papers, known as the Annus Mirabilis papers, but historians of physics who have studied the issue find no evidence that she made any substantive contributions. === Marriages and children === An early correspondence between Einstein and Marić was discovered and published in 1987 which revealed that the couple had a daughter named "Lieserl", born in early 1902 in Novi Sad where Marić was staying with her parents. Marić returned to Switzerland without the child, whose real name and fate are unknown. The contents of Einstein's letter in September 1903 suggest that the girl was either given up for adoption or died of scarlet fever in infancy. Einstein and Marić married in January 1903. In May 1904, their son Hans Albert Einstein was born in Bern, Switzerland. Their son Eduard was born in Zürich in July 1910. The couple moved to Berlin in April 1914, but Marić returned to Zürich with their sons after learning that Einstein's chief romantic attraction was his first and second cousin Elsa. They divorced on 14 February 1919, having lived apart for five years. Eduard had a breakdown at about age 20 and was diagnosed with schizophrenia. His mother cared for him and he was also committed to asylums for several periods, finally being committed permanently after her death.In letters revealed in 2015, Einstein wrote to his early love Marie Winteler about his marriage and his strong feelings for her. He wrote in 1910, while his wife was pregnant with their second child: "I think of you in heartfelt love every spare minute and am so unhappy as only a man can be". He spoke about a "misguided love" and a "missed life" regarding his love for Marie.Einstein married Elsa Löwenthal in 1919, after having a relationship with her since 1912. She was a first cousin maternally and a second cousin paternally. They emigrated to the United States in 1933, and she was diagnosed with heart and kidney problems in 1935. She died in December 1936. === Friends === Among Einstein's well-known friends were Michele Besso, Paul Ehrenfest, Marcel Grossmann, János Plesch, Daniel Q. Posin, Maurice Solovine, and Stephen Wise. === Patent office === After graduating in 1900, Einstein spent almost two frustrating years searching for a teaching post. He acquired Swiss citizenship in February 1901, but was not conscripted for medical reasons. With the help of Marcel Grossmann's father, he secured a job in Bern at the Federal Office for Intellectual Property, the patent office, as an assistant examiner – level III.Einstein evaluated patent applications for a variety of devices including a gravel sorter and an electromechanical typewriter. In 1903, his position at the Swiss Patent Office became permanent, although he was passed over for promotion until he "fully mastered machine technology".Much of his work at the patent office related to questions about transmission of electric signals and electrical-mechanical synchronization of time, two technical problems that show up conspicuously in the thought experiments that eventually led Einstein to his radical conclusions about the nature of light and the fundamental connection between space and time.With a few friends he had met in Bern, Einstein started a small discussion group in 1902, self-mockingly named "The Olympia Academy", which met regularly to discuss science and philosophy. Their readings included the works of Henri Poincaré, Ernst Mach, and David Hume, which influenced his scientific and philosophical outlook. ==== First scientific papers ==== In 1900, Einstein's paper "Folgerungen aus den Capillaritätserscheinungen" ("Conclusions from the Capillarity Phenomena") was published in the journal Annalen der Physik. On 30 April 1905, Einstein completed his thesis, with Alfred Kleiner, Professor of Experimental Physics, serving as pro-forma advisor. As a result, Einstein was awarded a PhD by the University of Zürich, with his dissertation "A New Determination of Molecular Dimensions".In that same year, which has been called Einstein's annus mirabilis (miracle year), he published four groundbreaking papers, on the photoelectric effect, Brownian motion, special relativity, and the equivalence of mass and energy, which were to bring him to the notice of the academic world, at the age of 26. === Academic career === By 1908, he was recognized as a leading scientist and was appointed lecturer at the University of Bern. The following year, after giving a lecture on electrodynamics and the relativity principle at the University of Zürich, Alfred Kleiner recommended him to the faculty for a newly created professorship in theoretical physics. Einstein was appointed associate professor in 1909.Einstein became a full professor at the German Charles-Ferdinand University in Prague in April 1911, accepting Austrian citizenship in the Austro-Hungarian Empire to do so. During his Prague stay, he wrote 11 scientific works, five of them on radiation mathematics and on the quantum theory of solids. In July 1912, he returned to his alma mater in Zürich. From 1912 until 1914, he was professor of theoretical physics at the ETH Zurich, where he taught analytical mechanics and thermodynamics. He also studied continuum mechanics, the molecular theory of heat, and the problem of gravitation, on which he worked with mathematician and friend Marcel Grossmann.On 3 July 1913, he was voted for membership in the Prussian Academy of Sciences in Berlin. Max Planck and Walther Nernst visited him the next week in Zurich to persuade him to join the academy, additionally offering him the post of director at the Kaiser Wilhelm Institute for Physics, which was soon to be established. (Membership in the academy included paid salary and professorship without teaching duties at the Humboldt University of Berlin.) He was officially elected to the academy on 24 July, and he accepted to move to the German Empire the next year. His decision to move to Berlin was also influenced by the prospect of living near his cousin Elsa, with whom he had developed a romantic affair. He joined the academy and thus the Berlin University on 1 April 1914. As World War I broke out that year, the plan for Kaiser Wilhelm Institute for Physics was aborted. The institute was established on 1 October 1917, with Einstein as its director. In 1916, Einstein was elected president of the German Physical Society (1916–1918).Based on calculations Einstein made in 1911, about his new theory of general relativity, light from another star should be bent by the Sun's gravity. In 1919, that prediction was confirmed by Sir Arthur Eddington during the solar eclipse of 29 May 1919. Those observations were published in the international media, making Einstein world famous. On 7 November 1919, the leading British newspaper The Times printed a banner headline that read: "Revolution in Science – New Theory of the Universe – Newtonian Ideas Overthrown".In 1920, he became a Foreign Member of the Royal Netherlands Academy of Arts and Sciences. In 1922, he was awarded the 1921 Nobel Prize in Physics "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect". While the general theory of relativity was still considered somewhat controversial, the citation also does not treat the cited work as an explanation but merely as a discovery of the law, as the idea of photons was considered outlandish and did not receive universal acceptance until the 1924 derivation of the Planck spectrum by S. N. Bose. Einstein was elected a Foreign Member of the Royal Society (ForMemRS) in 1921. He also received the Copley Medal from the Royal Society in 1925. === 1921–1922: Travels abroad === Einstein visited New York City for the first time on 2 April 1921, where he received an official welcome by Mayor John Francis Hylan, followed by three weeks of lectures and receptions. He went on to deliver several lectures at Columbia University and Princeton University, and in Washington he accompanied representatives of the National Academy of Science on a visit to the White House. On his return to Europe he was the guest of the British statesman and philosopher Viscount Haldane in London, where he met several renowned scientific, intellectual and political figures, and delivered a lecture at King's College London. He also published an essay, "My First Impression of the U.S.A.," in July 1921, in which he tried briefly to describe some characteristics of Americans, much as had Alexis de Tocqueville, who published his own impressions in Democracy in America (1835). For some of his observations, Einstein was clearly surprised: "What strikes a visitor is the joyous, positive attitude to life ... The American is friendly, self-confident, optimistic, and without envy."In 1922, his travels took him to Asia and later to Palestine, as part of a six-month excursion and speaking tour, as he visited Singapore, Ceylon and Japan, where he gave a series of lectures to thousands of Japanese. After his first public lecture, he met the emperor and empress at the Imperial Palace, where thousands came to watch. In a letter to his sons, he described his impression of the Japanese as being modest, intelligent, considerate, and having a true feel for art.Because of Einstein's travels to the Far East, he was unable to personally accept the Nobel Prize for Physics at the Stockholm award ceremony in December 1922. In his place, the banquet speech was held by a German diplomat, who praised Einstein not only as a scientist but also as an international peacemaker and activist.On his return voyage, he visited Palestine for 12 days in what would become his only visit to that region. He was greeted as if he were a head of state, rather than a physicist, which included a cannon salute upon arriving at the home of the British high commissioner, Sir Herbert Samuel. During one reception, the building was stormed by people who wanted to see and hear him. In Einstein's talk to the audience, he expressed happiness that the Jewish people were beginning to be recognized as a force in the world.Einstein visited Spain for two weeks in 1923, where he briefly met Santiago Ramón y Cajal and also received a diploma from King Alfonso XIII naming him a member of the Spanish Academy of Sciences.From 1922 to 1932, Einstein was a member of the International Committee on Intellectual Cooperation of the League of Nations in Geneva, a body created to promote international exchange between scientists, researchers, teachers, artists and intellectuals. Originally slated to serve as the Swiss delegate, Secretary-General Eric Drummond was persuaded by Catholic activists Oskar Halecki and Giuseppe Motta to instead have him become the German delegate, thus allowing Gonzague de Reynold to take the Swiss spot, from which he promoted traditionalist Catholic values. His former physics professor Hendrik Lorentz and the French chemist Marie Curie were also members of the committee. === 1930–1931: Travel to the US === In December 1930, Einstein visited America for the second time, originally intended as a two-month working visit as a research fellow at the California Institute of Technology. After the national attention he received during his first trip to the US, he and his arrangers aimed to protect his privacy. Although swamped with telegrams and invitations to receive awards or speak publicly, he declined them all.After arriving in New York City, Einstein was taken to various places and events, including Chinatown, a lunch with the editors of The New York Times, and a performance of Carmen at the Metropolitan Opera, where he was cheered by the audience on his arrival. During the days following, he was given the keys to the city by Mayor Jimmy Walker and met the president of Columbia University, who described Einstein as "the ruling monarch of the mind". Harry Emerson Fosdick, pastor at New York's Riverside Church, gave Einstein a tour of the church and showed him a full-size statue that the church made of Einstein, standing at the entrance. Also during his stay in New York, he joined a crowd of 15,000 people at Madison Square Garden during a Hanukkah celebration. Einstein next traveled to California, where he met Caltech president and Nobel laureate, Robert A. Millikan. His friendship with Millikan was "awkward", as Millikan "had a penchant for patriotic militarism," where Einstein was a pronounced pacifist. During an address to Caltech's students, Einstein noted that science was often inclined to do more harm than good.This aversion to war also led Einstein to befriend author Upton Sinclair and film star Charlie Chaplin, both noted for their pacifism. Carl Laemmle, head of Universal Studios, gave Einstein a tour of his studio and introduced him to Chaplin. They had an instant rapport, with Chaplin inviting Einstein and his wife, Elsa, to his home for dinner. Chaplin said Einstein's outward persona, calm and gentle, seemed to conceal a "highly emotional temperament," from which came his "extraordinary intellectual energy".Chaplin's film, City Lights, was to premiere a few days later in Hollywood, and Chaplin invited Einstein and Elsa to join him as his special guests. Walter Isaacson, Einstein's biographer, described this as "one of the most memorable scenes in the new era of celebrity". Chaplin visited Einstein at his home on a later trip to Berlin, and recalled his "modest little flat" and the piano at which he had begun writing his theory. Chaplin speculated that it was "possibly used as kindling wood by the Nazis." === 1933: Emigration to the US === In February 1933 while on a visit to the United States, Einstein knew he could not return to Germany with the rise to power of the Nazis under Germany's new chancellor, Adolf Hitler.While at American universities in early 1933, he undertook his third two-month visiting professorship at the California Institute of Technology in Pasadena. He and his wife Elsa returned to Belgium by ship in March, and during the trip they learned that their cottage was raided by the Nazis and his personal sailboat confiscated. Upon landing in Antwerp on 28 March, he immediately went to the German consulate and surrendered his passport, formally renouncing his German citizenship. The Nazis later sold his boat and converted his cottage into a Hitler Youth camp. ==== Refugee status ==== In April 1933, Einstein discovered that the new German government had passed laws barring Jews from holding any official positions, including teaching at universities. Historian Gerald Holton describes how, with "virtually no audible protest being raised by their colleagues", thousands of Jewish scientists were suddenly forced to give up their university positions and their names were removed from the rolls of institutions where they were employed.A month later, Einstein's works were among those targeted by the German Student Union in the Nazi book burnings, with Nazi propaganda minister Joseph Goebbels proclaiming, "Jewish intellectualism is dead." One German magazine included him in a list of enemies of the German regime with the phrase, "not yet hanged", offering a $5,000 bounty on his head. In a subsequent letter to physicist and friend Max Born, who had already emigrated from Germany to England, Einstein wrote, "... I must confess that the degree of their brutality and cowardice came as something of a surprise." After moving to the US, he described the book burnings as a "spontaneous emotional outburst" by those who "shun popular enlightenment," and "more than anything else in the world, fear the influence of men of intellectual independence."Einstein was now without a permanent home, unsure where he would live and work, and equally worried about the fate of countless other scientists still in Germany. He rented a house in De Haan, Belgium, where he lived for a few months. In late July 1933, he went to England for about six weeks at the personal invitation of British naval officer Commander Oliver Locker-Lampson, who had become friends with Einstein in the preceding years. To protect Einstein, Locker-Lampson had two assistants watch over him at his secluded cottage outside London, with photo of them carrying shotguns and guarding Einstein, published in the Daily Herald on 24 July 1933.Locker-Lampson took Einstein to meet Winston Churchill at his home, and later, Austen Chamberlain and former Prime Minister Lloyd George. Einstein asked them to help bring Jewish scientists out of Germany. British historian Martin Gilbert notes that Churchill responded immediately, and sent his friend, physicist Frederick Lindemann to Germany to seek out Jewish scientists and place them in British universities. Churchill later observed that as a result of Germany having driven the Jews out, they had lowered their "technical standards" and put the Allies' technology ahead of theirs.Einstein later contacted leaders of other nations, including Turkey's Prime Minister, İsmet İnönü, to whom he wrote in September 1933 requesting placement of unemployed German-Jewish scientists. As a result of Einstein's letter, Jewish invitees to Turkey eventually totaled over "1,000 saved individuals".Locker-Lampson also submitted a bill to parliament to extend British citizenship to Einstein, during which period Einstein made a number of public appearances describing the crisis brewing in Europe. In one of his speeches he denounced Germany's treatment of Jews, while at the same time he introduced a bill promoting Jewish citizenship in Palestine, as they were being denied citizenship elsewhere. In his speech he described Einstein as a "citizen of the world" who should be offered a temporary shelter in the UK. Both bills failed, however, and Einstein then accepted an earlier offer from the Institute for Advanced Study, in Princeton, New Jersey, US, to become a resident scholar. ==== Resident scholar at the Institute for Advanced Study ==== In October 1933 Einstein returned to the US and took up a position at the Institute for Advanced Study, noted for having become a refuge for scientists fleeing Nazi Germany. At the time, most American universities, including Harvard, Princeton and Yale, had minimal or no Jewish faculty or students, as a result of their Jewish quota which lasted until the late 1940s.Einstein was still undecided on his future. He had offers from several European universities, including Christ Church, Oxford where he stayed for three short periods between May 1931 and June 1933 and was offered a 5-year studentship, but in 1935 he arrived at the decision to remain permanently in the United States and apply for citizenship.Einstein's affiliation with the Institute for Advanced Study would last until his death in 1955. He was one of the four first selected (two of the others being John von Neumann and Kurt Gödel) at the new Institute, where he soon developed a close friendship with Gödel. The two would take long walks together discussing their work. Bruria Kaufman, his assistant, later became a physicist. During this period, Einstein tried to develop a unified field theory and to refute the accepted interpretation of quantum physics, both unsuccessfully. ==== World War II and the Manhattan Project ==== In 1939, a group of Hungarian scientists that included émigré physicist Leó Szilárd attempted to alert Washington to ongoing Nazi atomic bomb research. The group's warnings were discounted. Einstein and Szilárd, along with other refugees such as Edward Teller and Eugene Wigner, "regarded it as their responsibility to alert Americans to the possibility that German scientists might win the race to build an atomic bomb, and to warn that Hitler would be more than willing to resort to such a weapon." To make certain the US was aware of the danger, in July 1939, a few months before the beginning of World War II in Europe, Szilárd and Wigner visited Einstein to explain the possibility of atomic bombs, which Einstein, a pacifist, said he had never considered. He was asked to lend his support by writing a letter, with Szilárd, to President Roosevelt, recommending the US pay attention and engage in its own nuclear weapons research. The letter is believed to be "arguably the key stimulus for the U.S. adoption of serious investigations into nuclear weapons on the eve of the U.S. entry into World War II". In addition to the letter, Einstein used his connections with the Belgian Royal Family and the Belgian queen mother to get access with a personal envoy to the White House's Oval Office. Some say that as a result of Einstein's letter and his meetings with Roosevelt, the US entered the "race" to develop the bomb, drawing on its "immense material, financial, and scientific resources" to initiate the Manhattan Project. For Einstein, "war was a disease ... [and] he called for resistance to war." By signing the letter to Roosevelt, some argue he went against his pacifist principles. In 1954, a year before his death, Einstein said to his old friend, Linus Pauling, "I made one great mistake in my life—when I signed the letter to President Roosevelt recommending that atom bombs be made; but there was some justification—the danger that the Germans would make them ..." ==== US citizenship ==== Einstein became an American citizen in 1940. Not long after settling into his career at the Institute for Advanced Study (in Princeton, New Jersey), he expressed his appreciation of the meritocracy in American culture when compared to Europe. He recognized the "right of individuals to say and think what they pleased", without social barriers, and as a result, individuals were encouraged, he said, to be more creative, a trait he valued from his own early education. === Personal life === ==== Views on race ==== In his travel diaries from his 1922-23 visit to Asia, he expresses xenophobic and racist judgments on the Chinese, Japanese and Indian people he saw.Einstein joined National Association for the Advancement of Colored People (NAACP) in Princeton, where he campaigned for the civil rights of African Americans. He considered racism America's "worst disease," seeing it as "handed down from one generation to the next". As part of his involvement, he corresponded with civil rights activist W. E. B. Du Bois and was prepared to testify on his behalf during his trial in 1951. When Einstein offered to be a character witness for Du Bois, the judge decided to drop the case. In 1946 Einstein visited Lincoln University in Pennsylvania, a historically black college, where he was awarded an honorary degree. (Lincoln was the first university in the United States to grant college degrees to African Americans; alumni include Langston Hughes and Thurgood Marshall.) Einstein gave a speech about racism in America, adding, "I do not intend to be quiet about it." A resident of Princeton recalls that Einstein had once paid the college tuition for a black student. ==== Assisting Zionist causes ==== Einstein was a figurehead leader in helping establish the Hebrew University of Jerusalem, which opened in 1925, and was among its first Board of Governors. Earlier, in 1921, he was asked by the biochemist and president of the World Zionist Organization, Chaim Weizmann, to help raise funds for the planned university. He also submitted various suggestions as to its initial programs. Among those, he advised first creating an Institute of Agriculture in order to settle the undeveloped land. That should be followed, he suggested, by a Chemical Institute and an Institute of Microbiology, to fight the various ongoing epidemics such as malaria, which he called an "evil" that was undermining a third of the country's development. Establishing an Oriental Studies Institute, to include language courses given in both Hebrew and Arabic, for scientific exploration of the country and its historical monuments, was also important.Chaim Weizmann later became Israel's first president. Upon his death while in office in November 1952 and at the urging of Ezriel Carlebach, Prime Minister David Ben-Gurion offered Einstein the position of President of Israel, a mostly ceremonial post. The offer was presented by Israel's ambassador in Washington, Abba Eban, who explained that the offer "embodies the deepest respect which the Jewish people can repose in any of its sons". Einstein declined, and wrote in his response that he was "deeply moved", and "at once saddened and ashamed" that he could not accept it. ==== Love of music ==== Einstein developed an appreciation for music at an early age, and later wrote: "If I were not a physicist, I would probably be a musician. I often think in music. I live my daydreams in music. I see my life in terms of music... I get most joy in life out of music."His mother played the piano reasonably well and wanted her son to learn the violin, not only to instill in him a love of music but also to help him assimilate into German culture. According to conductor Leon Botstein, Einstein began playing when he was 5, although he did not enjoy it at that age.When he turned 13, he discovered the violin sonatas of Mozart, whereupon "Einstein fell in love" with Mozart's music and studied music more willingly. He taught himself to play without "ever practicing systematically", he said, deciding that "love is a better teacher than a sense of duty." At age 17, he was heard by a school examiner in Aarau as he played Beethoven's violin sonatas, the examiner stating afterward that his playing was "remarkable and revealing of 'great insight'." What struck the examiner, writes Botstein, was that Einstein "displayed a deep love of the music, a quality that was and remains in short supply. Music possessed an unusual meaning for this student."Music took on a pivotal and permanent role in Einstein's life from that period on. Although the idea of becoming a professional musician himself was not on his mind at any time, among those with whom Einstein played chamber music were a few professionals, and he performed for private audiences and friends. Chamber music had also become a regular part of his social life while living in Bern, Zürich, and Berlin, where he played with Max Planck and his son, among others. He is sometimes erroneously credited as the editor of the 1937 edition of the Köchel catalogue of Mozart's work; that edition was prepared by Alfred Einstein, who may have been a distant relation.In 1931, while engaged in research at the California Institute of Technology, he visited the Zoellner family conservatory in Los Angeles, where he played some of Beethoven and Mozart's works with members of the Zoellner Quartet. Near the end of his life, when the young Juilliard Quartet visited him in Princeton, he played his violin with them, and the quartet was "impressed by Einstein's level of coordination and intonation". ==== Political and religious views ==== Einstein's political view was in favor of socialism and critical of capitalism, which he detailed in his essays such as "Why Socialism?". Einstein offered and was called on to give judgments and opinions on matters often unrelated to theoretical physics or mathematics. He strongly advocated the idea of a democratic global government that would check the power of nation-states in the framework of a world federation. The FBI created a secret dossier on Einstein in 1932, and by the time of his death his FBI file was 1,427 pages long.Einstein was deeply impressed by Mahatma Gandhi. He exchanged written letters with Gandhi, and called him "a role model for the generations to come" in a letter writing about him.Einstein spoke of his spiritual outlook in a wide array of original writings and interviews. Einstein stated that he had sympathy for the impersonal pantheistic God of Baruch Spinoza's philosophy. He did not believe in a personal God who concerns himself with fates and actions of human beings, a view which he described as naïve. He clarified, however, that "I am not an atheist", preferring to call himself an agnostic, or a "deeply religious nonbeliever." When asked if he believed in an afterlife, Einstein replied, "No. And one life is enough for me."Einstein was primarily affiliated with non-religious humanist and Ethical Culture groups in both the UK and US. He served on the advisory board of the First Humanist Society of New York, and was an honorary associate of the Rationalist Association, which publishes New Humanist in Britain. For the seventy-fifth anniversary of the New York Society for Ethical Culture, he stated that the idea of Ethical Culture embodied his personal conception of what is most valuable and enduring in religious idealism. He observed, "Without 'ethical culture' there is no salvation for humanity." === Death === On 17 April 1955, Einstein experienced internal bleeding caused by the rupture of an abdominal aortic aneurysm, which had previously been reinforced surgically by Rudolph Nissen in 1948. He took the draft of a speech he was preparing for a television appearance commemorating the State of Israel's seventh anniversary with him to the hospital, but he did not live long enough to complete it.Einstein refused surgery, saying, "I want to go when I want. It is tasteless to prolong life artificially. I have done my share; it is time to go. I will do it elegantly." He died in Princeton Hospital early the next morning at the age of 76, having continued to work until near the end.During the autopsy, the pathologist of Princeton Hospital, Thomas Stoltz Harvey, removed Einstein's brain for preservation without the permission of his family, in the hope that the neuroscience of the future would be able to discover what made Einstein so intelligent. Einstein's remains were cremated and his ashes were scattered at an undisclosed location.In a memorial lecture delivered on 13 December 1965, at UNESCO headquarters, nuclear physicist Robert Oppenheimer summarized his impression of Einstein as a person: "He was almost wholly without sophistication and wholly without worldliness ... There was always with him a wonderful purity at once childlike and profoundly stubborn." == Scientific career == Throughout his life, Einstein published hundreds of books and articles. He published more than 300 scientific papers and 150 non-scientific ones. On 5 December 2014, universities and archives announced the release of Einstein's papers, comprising more than 30,000 unique documents. Einstein's intellectual achievements and originality have made the word "Einstein" synonymous with "genius." In addition to the work he did by himself he also collaborated with other scientists on additional projects including the Bose–Einstein statistics, the Einstein refrigerator and others. === 1905 – Annus Mirabilis papers === The Annus Mirabilis papers are four articles pertaining to the photoelectric effect (which gave rise to quantum theory), Brownian motion, the special theory of relativity, and E = mc2 that Einstein published in the Annalen der Physik scientific journal in 1905. These four works contributed substantially to the foundation of modern physics and changed views on space, time, and matter. The four papers are: === Statistical mechanics === ==== Thermodynamic fluctuations and statistical physics ==== Einstein's first paper submitted in 1900 to Annalen der Physik was on capillary attraction. It was published in 1901 with the title "Folgerungen aus den Capillaritätserscheinungen", which translates as "Conclusions from the capillarity phenomena". Two papers he published in 1902–1903 (thermodynamics) attempted to interpret atomic phenomena from a statistical point of view. These papers were the foundation for the 1905 paper on Brownian motion, which showed that Brownian movement can be construed as firm evidence that molecules exist. His research in 1903 and 1904 was mainly concerned with the effect of finite atomic size on diffusion phenomena. ==== Theory of critical opalescence ==== Einstein returned to the problem of thermodynamic fluctuations, giving a treatment of the density variations in a fluid at its critical point. Ordinarily the density fluctuations are controlled by the second derivative of the free energy with respect to the density. At the critical point, this derivative is zero, leading to large fluctuations. The effect of density fluctuations is that light of all wavelengths is scattered, making the fluid look milky white. Einstein relates this to Rayleigh scattering, which is what happens when the fluctuation size is much smaller than the wavelength, and which explains why the sky is blue. Einstein quantitatively derived critical opalescence from a treatment of density fluctuations, and demonstrated how both the effect and Rayleigh scattering originate from the atomistic constitution of matter. === Special relativity === ==== General principles ==== He articulated the principle of relativity. This was understood by Hermann Minkowski to be a generalization of rotational invariance from space to space-time. Other principles postulated by Einstein and later vindicated are the principle of equivalence, general covariance and the principle of adiabatic invariance of the quantum number. ==== Theory of relativity and E = mc² ==== Einstein's "Zur Elektrodynamik bewegter Körper" ("On the Electrodynamics of Moving Bodies") was received on 30 June 1905 and published 26 September of that same year. It reconciles Maxwell's equations for electricity and magnetism with the laws of mechanics, by introducing major changes to mechanics close to the speed of light. This later became known as Einstein's special theory of relativity. Consequences of this include the time–space frame of a moving body appearing to slow down and contract (in the direction of motion) when measured in the frame of the observer. This paper also argued that the idea of a luminiferous aether—one of the leading theoretical entities in physics at the time—was superfluous.In his paper on mass–energy equivalence, Einstein produced E = mc2 from his special relativity equations. Einstein's 1905 work on relativity remained controversial for many years, but was accepted by leading physicists, starting with Max Planck. === General relativity === ==== General relativity and the equivalence principle ==== General relativity (GR) is a theory of gravitation that was developed by Einstein between 1907 and 1915. According to general relativity, the observed gravitational attraction between masses results from the warping of space and time by those masses. General relativity has developed into an essential tool in modern astrophysics. It provides the foundation for the current understanding of black holes, regions of space where gravitational attraction is so strong that not even light can escape. As Einstein later said, the reason for the development of general relativity was that the preference of inertial motions within special relativity was unsatisfactory, while a theory which from the outset prefers no state of motion (even accelerated ones) should appear more satisfactory. Consequently, in 1907 he published an article on acceleration under special relativity. In that article titled "On the Relativity Principle and the Conclusions Drawn from It", he argued that free fall is really inertial motion, and that for a free-falling observer the rules of special relativity must apply. This argument is called the equivalence principle. In the same article, Einstein also predicted the phenomena of gravitational time dilation, gravitational red shift and deflection of light.In 1911, Einstein published another article "On the Influence of Gravitation on the Propagation of Light" expanding on the 1907 article, in which he estimated the amount of deflection of light by massive bodies. Thus, the theoretical prediction of general relativity could for the first time be tested experimentally. ==== Gravitational waves ==== In 1916, Einstein predicted gravitational waves, ripples in the curvature of spacetime which propagate as waves, traveling outward from the source, transporting energy as gravitational radiation. The existence of gravitational waves is possible under general relativity due to its Lorentz invariance which brings the concept of a finite speed of propagation of the physical interactions of gravity with it. By contrast, gravitational waves cannot exist in the Newtonian theory of gravitation, which postulates that the physical interactions of gravity propagate at infinite speed. The first, indirect, detection of gravitational waves came in the 1970s through observation of a pair of closely orbiting neutron stars, PSR B1913+16. The explanation of the decay in their orbital period was that they were emitting gravitational waves. Einstein's prediction was confirmed on 11 February 2016, when researchers at LIGO published the first observation of gravitational waves, detected on Earth on 14 September 2015, exactly one hundred years after the prediction. ==== Hole argument and Entwurf theory ==== While developing general relativity, Einstein became confused about the gauge invariance in the theory. He formulated an argument that led him to conclude that a general relativistic field theory is impossible. He gave up looking for fully generally covariant tensor equations, and searched for equations that would be invariant under general linear transformations only. In June 1913, the Entwurf ("draft") theory was the result of these investigations. As its name suggests, it was a sketch of a theory, less elegant and more difficult than general relativity, with the equations of motion supplemented by additional gauge fixing conditions. After more than two years of intensive work, Einstein realized that the hole argument was mistaken and abandoned the theory in November 1915. ==== Physical cosmology ==== In 1917, Einstein applied the general theory of relativity to the structure of the universe as a whole. He discovered that the general field equations predicted a universe that was dynamic, either contracting or expanding. As observational evidence for a dynamic universe was not known at the time, Einstein introduced a new term, the cosmological constant, to the field equations, in order to allow the theory to predict a static universe. The modified field equations predicted a static universe of closed curvature, in accordance with Einstein's understanding of Mach's principle in these years. This model became known as the Einstein World or Einstein's static universe.Following the discovery of the recession of the nebulae by Edwin Hubble in 1929, Einstein abandoned his static model of the universe, and proposed two dynamic models of the cosmos, The Friedmann-Einstein universe of 1931 and the Einstein–de Sitter universe of 1932. In each of these models, Einstein discarded the cosmological constant, claiming that it was "in any case theoretically unsatisfactory".In many Einstein biographies, it is claimed that Einstein referred to the cosmological constant in later years as his "biggest blunder". The astrophysicist Mario Livio has recently cast doubt on this claim, suggesting that it may be exaggerated.In late 2013, a team led by the Irish physicist Cormac O'Raifeartaigh discovered evidence that, shortly after learning of Hubble's observations of the recession of the nebulae, Einstein considered a steady-state model of the universe. In a hitherto overlooked manuscript, apparently written in early 1931, Einstein explored a model of the expanding universe in which the density of matter remains constant due to a continuous creation of matter, a process he associated with the cosmological constant. As he stated in the paper, "In what follows, I would like to draw attention to a solution to equation (1) that can account for Hubbel's [sic] facts, and in which the density is constant over time" ... "If one considers a physically bounded volume, particles of matter will be continually leaving it. For the density to remain constant, new particles of matter must be continually formed in the volume from space." It thus appears that Einstein considered a steady-state model of the expanding universe many years before Hoyle, Bondi and Gold. However, Einstein's steady-state model contained a fundamental flaw and he quickly abandoned the idea. ==== Energy momentum pseudotensor ==== General relativity includes a dynamical spacetime, so it is difficult to see how to identify the conserved energy and momentum. Noether's theorem allows these quantities to be determined from a Lagrangian with translation invariance, but general covariance makes translation invariance into something of a gauge symmetry. The energy and momentum derived within general relativity by Noether's presecriptions do not make a real tensor for this reason. Einstein argued that this is true for fundamental reasons, because the gravitational field could be made to vanish by a choice of coordinates. He maintained that the non-covariant energy momentum pseudotensor was in fact the best description of the energy momentum distribution in a gravitational field. This approach has been echoed by Lev Landau and Evgeny Lifshitz, and others, and has become standard. The use of non-covariant objects like pseudotensors was heavily criticized in 1917 by Erwin Schrödinger and others. ==== Wormholes ==== In 1935, Einstein collaborated with Nathan Rosen to produce a model of a wormhole, often called Einstein–Rosen bridges. His motivation was to model elementary particles with charge as a solution of gravitational field equations, in line with the program outlined in the paper "Do Gravitational Fields play an Important Role in the Constitution of the Elementary Particles?". These solutions cut and pasted Schwarzschild black holes to make a bridge between two patches.If one end of a wormhole was positively charged, the other end would be negatively charged. These properties led Einstein to believe that pairs of particles and antiparticles could be described in this way. ==== Einstein–Cartan theory ==== In order to incorporate spinning point particles into general relativity, the affine connection needed to be generalized to include an antisymmetric part, called the torsion. This modification was made by Einstein and Cartan in the 1920s. ==== Equations of motion ==== The theory of general relativity has a fundamental law—the Einstein equations which describe how space curves, the geodesic equation which describes how particles move may be derived from the Einstein equations. Since the equations of general relativity are non-linear, a lump of energy made out of pure gravitational fields, like a black hole, would move on a trajectory which is determined by the Einstein equations themselves, not by a new law. So Einstein proposed that the path of a singular solution, like a black hole, would be determined to be a geodesic from general relativity itself. This was established by Einstein, Infeld, and Hoffmann for pointlike objects without angular momentum, and by Roy Kerr for spinning objects. === Old quantum theory === ==== Photons and energy quanta ==== In a 1905 paper, Einstein postulated that light itself consists of localized particles (quanta). Einstein's light quanta were nearly universally rejected by all physicists, including Max Planck and Niels Bohr. This idea only became universally accepted in 1919, with Robert Millikan's detailed experiments on the photoelectric effect, and with the measurement of Compton scattering. Einstein concluded that each wave of frequency f is associated with a collection of photons with energy hf each, where h is Planck's constant. He does not say much more, because he is not sure how the particles are related to the wave. But he does suggest that this idea would explain certain experimental results, notably the photoelectric effect. ==== Quantized atomic vibrations ==== In 1907, Einstein proposed a model of matter where each atom in a lattice structure is an independent harmonic oscillator. In the Einstein model, each atom oscillates independently—a series of equally spaced quantized states for each oscillator. Einstein was aware that getting the frequency of the actual oscillations would be difficult, but he nevertheless proposed this theory because it was a particularly clear demonstration that quantum mechanics could solve the specific heat problem in classical mechanics. Peter Debye refined this model. ==== Adiabatic principle and action-angle variables ==== Throughout the 1910s, quantum mechanics expanded in scope to cover many different systems. After Ernest Rutherford discovered the nucleus and proposed that electrons orbit like planets, Niels Bohr was able to show that the same quantum mechanical postulates introduced by Planck and developed by Einstein would explain the discrete motion of electrons in atoms, and the periodic table of the elements. Einstein contributed to these developments by linking them with the 1898 arguments Wilhelm Wien had made. Wien had shown that the hypothesis of adiabatic invariance of a thermal equilibrium state allows all the blackbody curves at different temperature to be derived from one another by a simple shifting process. Einstein noted in 1911 that the same adiabatic principle shows that the quantity which is quantized in any mechanical motion must be an adiabatic invariant. Arnold Sommerfeld identified this adiabatic invariant as the action variable of classical mechanics. ==== Bose–Einstein statistics ==== In 1924, Einstein received a description of a statistical model from Indian physicist Satyendra Nath Bose, based on a counting method that assumed that light could be understood as a gas of indistinguishable particles. Einstein noted that Bose's statistics applied to some atoms as well as to the proposed light particles, and submitted his translation of Bose's paper to the Zeitschrift für Physik. Einstein also published his own articles describing the model and its implications, among them the Bose–Einstein condensate phenomenon that some particulates should appear at very low temperatures. It was not until 1995 that the first such condensate was produced experimentally by Eric Allin Cornell and Carl Wieman using ultra-cooling equipment built at the NIST–JILA laboratory at the University of Colorado at Boulder. Bose–Einstein statistics are now used to describe the behaviors of any assembly of bosons. Einstein's sketches for this project may be seen in the Einstein Archive in the library of the Leiden University. ==== Wave–particle duality ==== Although the patent office promoted Einstein to Technical Examiner Second Class in 1906, he had not given up on academia. In 1908, he became a Privatdozent at the University of Bern. In "Über die Entwicklung unserer Anschauungen über das Wesen und die Konstitution der Strahlung" ("The Development of our Views on the Composition and Essence of Radiation"), on the quantization of light, and in an earlier 1909 paper, Einstein showed that Max Planck's energy quanta must have well-defined momenta and act in some respects as independent, point-like particles. This paper introduced the photon concept (although the name photon was introduced later by Gilbert N. Lewis in 1926) and inspired the notion of wave–particle duality in quantum mechanics. Einstein saw this wave–particle duality in radiation as concrete evidence for his conviction that physics needed a new, unified foundation. ==== Zero-point energy ==== In a series of works completed from 1911 to 1913, Planck reformulated his 1900 quantum theory and introduced the idea of zero-point energy in his "second quantum theory". Soon, this idea attracted the attention of Einstein and his assistant Otto Stern. Assuming the energy of rotating diatomic molecules contains zero-point energy, they then compared the theoretical specific heat of hydrogen gas with the experimental data. The numbers matched nicely. However, after publishing the findings, they promptly withdrew their support, because they no longer had confidence in the correctness of the idea of zero-point energy. ==== Stimulated emission ==== In 1917, at the height of his work on relativity, Einstein published an article in Physikalische Zeitschrift that proposed the possibility of stimulated emission, the physical process that makes possible the maser and the laser. This article showed that the statistics of absorption and emission of light would only be consistent with Planck's distribution law if the emission of light into a mode with n photons would be enhanced statistically compared to the emission of light into an empty mode. This paper was enormously influential in the later development of quantum mechanics, because it was the first paper to show that the statistics of atomic transitions had simple laws. ==== Matter waves ==== Einstein discovered Louis de Broglie's work and supported his ideas, which were received skeptically at first. In another major paper from this era, Einstein gave a wave equation for de Broglie waves, which Einstein suggested was the Hamilton–Jacobi equation of mechanics. This paper would inspire Schrödinger's work of 1926. === Quantum mechanics === ==== Einstein's objections to quantum mechanics ==== Einstein was displeased with modern quantum mechanics as it had evolved after 1925. Contrary to popular belief, his doubts were not due to a conviction that God "is not playing at dice." Indeed, it was Einstein himself, in his 1917 paper that proposed the possibility of stimulated emission, who first proposed the fundamental role of chance in explaining quantum processes. Rather, he objected to what quantum mechanics implies about the nature of reality. Einstein believed that a physical reality exists independent of our ability to observe it. In contrast, Bohr and his followers maintained that all we can know are the results of measurements and observations, and that it makes no sense to speculate about an ultimate reality that exists beyond our perceptions. ==== Bohr versus Einstein ==== The Bohr–Einstein debates were a series of public disputes about quantum mechanics between Einstein and Niels Bohr, who were two of its founders. Their debates are remembered because of their importance to the philosophy of science. Their debates would influence later interpretations of quantum mechanics. ==== Einstein–Podolsky–Rosen paradox ==== In 1935, Einstein returned to the question of quantum mechanics in the "EPR paper". In a thought experiment, he considered two particles which had interacted such that their properties were strongly correlated. No matter how far the two particles were separated, a precise position measurement on one particle would result in equally precise knowledge of the position of the other particle; likewise a precise momentum measurement of one particle would result in equally precise knowledge of the momentum of the other particle, without needing to disturb the other particle in any way.Given Einstein's concept of local realism, there were two possibilities: (1) either the other particle had these properties already determined, or (2) the process of measuring the first particle instantaneously affected the reality of the position and momentum of the second particle. Einstein rejected this second possibility (popularly called "spooky action at a distance").This principle distilled the essence of Einstein's objection to quantum mechanics. As a physical principle, it was shown to be incorrect when the Aspect experiment of 1982 confirmed Bell's theorem, which J. S. Bell had delineated in 1964. The results of these and subsequent experiments demonstrate that quantum physics cannot be represented by any version of the classical picture of physics.Although Einstein was wrong, his clear prediction of the unusual properties of entangled quantum states has resulted in the EPR paper becoming among the top ten papers published in Physical Review. It is considered a centerpiece of the development of quantum information theory. === Unified field theory === Following his research on general relativity, Einstein entered into a series of attempts to generalize his geometric theory of gravitation to include electromagnetism as another aspect of a single entity. In 1950, he described his "unified field theory" in a Scientific American article titled "On the Generalized Theory of Gravitation". Although he continued to be lauded for his work, Einstein became increasingly isolated in his research, and his efforts were ultimately unsuccessful. In his pursuit of a unification of the fundamental forces, Einstein ignored some mainstream developments in physics, most notably the strong and weak nuclear forces, which were not well understood until many years after his death. Mainstream physics, in turn, largely ignored Einstein's approaches to unification. Einstein's dream of unifying other laws of physics with gravity motivates modern quests for a theory of everything and in particular string theory, where geometrical fields emerge in a unified quantum-mechanical setting. === Other investigations === Einstein conducted other investigations that were unsuccessful and abandoned. These pertain to force, superconductivity, and other research. === Collaboration with other scientists === In addition to longtime collaborators Leopold Infeld, Nathan Rosen, Peter Bergmann and others, Einstein also had some one-shot collaborations with various scientists. ==== Einstein–de Haas experiment ==== Einstein and De Haas demonstrated that magnetization is due to the motion of electrons, nowadays known to be the spin. In order to show this, they reversed the magnetization in an iron bar suspended on a torsion pendulum. They confirmed that this leads the bar to rotate, because the electron's angular momentum changes as the magnetization changes. This experiment needed to be sensitive, because the angular momentum associated with electrons is small, but it definitively established that electron motion of some kind is responsible for magnetization. ==== Schrödinger gas model ==== Einstein suggested to Erwin Schrödinger that he might be able to reproduce the statistics of a Bose–Einstein gas by considering a box. Then to each possible quantum motion of a particle in a box associate an independent harmonic oscillator. Quantizing these oscillators, each level will have an integer occupation number, which will be the number of particles in it. This formulation is a form of second quantization, but it predates modern quantum mechanics. Erwin Schrödinger applied this to derive the thermodynamic properties of a semiclassical ideal gas. Schrödinger urged Einstein to add his name as co-author, although Einstein declined the invitation. ==== Einstein refrigerator ==== In 1926, Einstein and his former student Leó Szilárd co-invented (and in 1930, patented) the Einstein refrigerator. This absorption refrigerator was then revolutionary for having no moving parts and using only heat as an input. On 11 November 1930, U.S. Patent 1,781,541 was awarded to Einstein and Leó Szilárd for the refrigerator. Their invention was not immediately put into commercial production, and the most promising of their patents were acquired by the Swedish company Electrolux. == Non-scientific legacy == While traveling, Einstein wrote daily to his wife Elsa and adopted stepdaughters Margot and Ilse. The letters were included in the papers bequeathed to The Hebrew University. Margot Einstein permitted the personal letters to be made available to the public, but requested that it not be done until twenty years after her death (she died in 1986). Einstein had expressed his interest in the plumbing profession and was made an honorary member of the Plumbers and Steamfitters Union. Barbara Wolff, of The Hebrew University's Albert Einstein Archives, told the BBC that there are about 3,500 pages of private correspondence written between 1912 and 1955.Corbis, successor to The Roger Richman Agency, licenses the use of his name and associated imagery, as agent for the university. == In popular culture == In the period before World War II, The New Yorker published a vignette in their "The Talk of the Town" feature saying that Einstein was so well known in America that he would be stopped on the street by people wanting him to explain "that theory". He finally figured out a way to handle the incessant inquiries. He told his inquirers "Pardon me, sorry! Always I am mistaken for Professor Einstein."Einstein has been the subject of or inspiration for many novels, films, plays, and works of music. He is a favorite model for depictions of mad scientists and absent-minded professors; his expressive face and distinctive hairstyle have been widely copied and exaggerated. Time magazine's Frederic Golden wrote that Einstein was "a cartoonist's dream come true".Quotes are falsely attributed to him. == Awards and honors == Einstein received numerous awards and honors and in 1922 he was awarded the 1921 Nobel Prize in Physics "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect". None of the nominations in 1921 met the criteria set by Alfred Nobel, so the 1921 prize was carried forward and awarded to Einstein in 1922. == Publications == The following publications by Einstein are referenced in this article.

### Instruction: retrieve labels for this: Afghanistan ( ( listen); Pashto/Dari: افغانستان‬, Pashto: Afġānistān [avɣɒnisˈtɒn, ab-], Dari: Afġānestān [avɣɒnesˈtɒn]), officially the Islamic Republic of Afghanistan, is a landlocked country located within South Asia and Central Asia. Afghanistan is bordered by Pakistan in the south and east; Iran in the west; Turkmenistan, Uzbekistan, and Tajikistan in the north; and in the far northeast, China. Its territory covers 652,000 square kilometers (252,000 sq mi) and much of it is covered by the Hindu Kush mountain range, which experience very cold winters. The north consists of fertile plains, whilst the south-west consists of deserts where temperatures can get very hot in summers. Kabul serves as the capital and its largest city. Human habitation in Afghanistan dates back to the Middle Paleolithic Era, and the country's strategic location along the Silk Road connected it to the cultures of the Middle East and other parts of Asia. The land has historically been home to various peoples and has witnessed numerous military campaigns, including those by Alexander the Great, Mauryas, Muslim Arabs, Mongols, British, Soviet, and since 2001 by the United States with NATO-allied countries. It has been called "unconquerable" and nicknamed the "graveyard of empires". The land also served as the source from which the Kushans, Hephthalites, Samanids, Saffarids, Ghaznavids, Ghorids, Khaljis, Mughals, Hotaks, Durranis, and others have risen to form major empires.The political history of the modern state of Afghanistan began with the Hotak and Durrani dynasties in the 18th century. In the late 19th century, Afghanistan became a buffer state in the "Great Game" between British India and the Russian Empire. Its border with British India, the Durand Line, was formed in 1893 but it is not recognized by the Afghan government and it has led to strained relations with Pakistan since the latter's independence in 1947. Following the Third Anglo-Afghan War in 1919 the country was free of foreign influence, eventually becoming a monarchy under King Amanullah, and later for 40 years under Zahir Shah. In the late 1970s, Afghanistan in a series of coups first became a socialist state and then a Soviet Union protectorate. This evoked the Soviet–Afghan War in the 1980s against rebels. By 1996 most of Afghanistan was captured by the fundamentalist Islamic group the Taliban, who ruled most of the country as a totalitarian regime for almost five years. The Taliban were forcibly removed by the NATO-led coalition, and a new democratically-elected government political structure was formed. Afghanistan is a unitary presidential Islamic republic with a population of 35 million, mostly composed of ethnic Pashtuns, Tajiks, Hazaras and Uzbeks. It is a member of the United Nations, the Organisation of Islamic Cooperation, the Group of 77, the Economic Cooperation Organization, and the Non-Aligned Movement. Afghanistan's economy is the world's 108th largest, with a GDP of $64.08 billion; the country fares much worse in terms of per-capita GDP (PPP), ranking 167th out of 186 countries in a 2016 report from the International Monetary Fund. == Etymology == The name Afghānistān (Pashto: افغانستان‬‎) is believed to be as old as the ethnonym Afghan, which is documented in the 10th-century geography book Hudud ul-'alam. The root name "Afghan" was used historically in reference to a member of the ethnic Pashtuns, and the suffix "-stan" means "place of" in Persian. Therefore, Afghanistan translates to land of the Afghans or, more specifically in a historical sense, to land of the Pashtuns. However, the modern Constitution of Afghanistan states that "[t]he word Afghan shall apply to every citizen of Afghanistan." == History == Excavations of prehistoric sites by Louis Dupree and others suggest that humans were living in what is now Afghanistan at least 50,000 years ago, and that farming communities in the area were among the earliest in the world. An important site of early historical activities, many believe that Afghanistan compares to Egypt in terms of the historical value of its archaeological sites.The country sits at a unique nexus point where numerous civilizations have interacted and often fought. It has been home to various peoples through the ages, among them the ancient Iranian peoples who established the dominant role of Indo-Iranian languages in the region. At multiple points, the land has been incorporated within large regional empires, among them the Achaemenid Empire, the Macedonian Empire, the Indian Maurya Empire, and the Islamic Empire.Many empires and kingdoms have also risen to power in Afghanistan, such as the Greco-Bactrians, Kushans, Hephthalites, Kabul Shahis, Saffarids, Samanids, Ghaznavids, Ghurids, Khaljis, Kartids, Timurids, Mughals, and finally the Hotak and Durrani dynasties that marked the political origins of the modern state. === Pre-Islamic period === Archaeological exploration done in the 20th century suggests that the geographical area of Afghanistan has been closely connected by culture and trade with its neighbors to the east, west, and north. Artifacts typical of the Paleolithic, Mesolithic, Neolithic, Bronze, and Iron ages have been found in Afghanistan. Urban civilization is believed to have begun as early as 3000 BCE, and the early city of Mundigak (near Kandahar in the south of the country) may have been a colony of the nearby Indus Valley Civilization. More recent findings established that the Indus Valley Civilisation stretched up towards modern-day Afghanistan, making the ancient civilisation today part of Pakistan, Afghanistan and India. In more detail, it extended from what today is northwest Pakistan to northwest India and northeast Afghanistan. An Indus Valley site has been found on the Oxus River at Shortugai in northern Afghanistan. There are several smaller IVC colonies to be found in Afghanistan as well. After 2000 BCE, successive waves of semi-nomadic people from Central Asia began moving south into Afghanistan; among them were many Indo-European-speaking Indo-Iranians. These tribes later migrated further into South Asia, Western Asia, and toward Europe via the area north of the Caspian Sea. The region at the time was referred to as Ariana.The religion Zoroastrianism is believed by some to have originated in what is now Afghanistan between 1800 and 800 BCE, as its founder Zoroaster is thought to have lived and died in Balkh. Ancient Eastern Iranian languages may have been spoken in the region around the time of the rise of Zoroastrianism. By the middle of the 6th century BCE, the Achaemenids overthrew the Medes and incorporated Arachosia, Aria, and Bactria within its eastern boundaries. An inscription on the tombstone of Darius I of Persia mentions the Kabul Valley in a list of the 29 countries that he had conquered.Alexander the Great and his Macedonian forces arrived to Afghanistan in 330 BCE after defeating Darius III of Persia a year earlier in the Battle of Gaugamela. Following Alexander's brief occupation, the successor state of the Seleucid Empire controlled the region until 305 BCE, when they gave much of it to the Maurya Empire as part of an alliance treaty. The Mauryans controlled the area south of the Hindu Kush until they were overthrown in about 185 BCE. Their decline began 60 years after Ashoka's rule ended, leading to the Hellenistic reconquest by the Greco-Bactrians. Much of it soon broke away from them and became part of the Indo-Greek Kingdom. They were defeated and expelled by the Indo-Scythians in the late 2nd century BCE.During the first century BCE, the Parthian Empire subjugated the region, but lost it to their Indo-Parthian vassals. In the mid-to-late first century CE the vast Kushan Empire, centered in Afghanistan, became great patrons of Buddhist culture, making Buddhism flourish throughout the region. The Kushans were overthrown by the Sassanids in the 3rd century CE, though the Indo-Sassanids continued to rule at least parts of the region. They were followed by the Kidarite who, in turn, were replaced by the Hephthalites. By the 6th century CE, the successors to the Kushans and Hepthalites established a small dynasty called Kabul Shahi. Much of the northeastern and southern areas of the country remained dominated by Buddhist culture. === Islamization and Mongol invasion === Arab Muslims brought Islam to Herat and Zaranj in 642 CE and began spreading eastward; some of the native inhabitants they encountered accepted it while others revolted. The land was collectively recognized by the Arabs as al-Hind due to its cultural connection with Greater India. Before Islam was introduced, people of the region were mostly Buddhists and Zoroastrians, but there were also Surya and Nana worshipers, Jews, and others. The Zunbils and Kabul Shahi were first conquered in 870 CE by the Saffarid Muslims of Zaranj. Later, the Samanids extended their Islamic influence south of the Hindu Kush. It is reported that Muslims and non-Muslims still lived side by side in Kabul before the Ghaznavids rose to power in the 10th century.By the 11th century, Mahmud of Ghazni defeated the remaining Hindu rulers and effectively Islamized the wider region, with the exception of Kafiristan. Afghanistan became one of the main centers in the Muslim world during this Islamic Golden Age. The Ghaznavid dynasty was overthrown by the Ghurids, who expanded and advanced the already powerful Islamic empire. In 1219 AD, Genghis Khan and his Mongol army overran the region. His troops are said to have annihilated the Khorasanian cities of Herat and Balkh as well as Bamyan. The destruction caused by the Mongols forced many locals to return to an agrarian rural society. Mongol rule continued with the Ilkhanate in the northwest while the Khalji dynasty administered the Afghan tribal areas south of the Hindu Kush until the invasion of Timur, who established the Timurid Empire in 1370. In the early 16th century, Babur arrived from Fergana and captured Kabul from the Arghun dynasty. In 1526, he invaded Delhi in India to replace the Lodi dynasty with the Mughal Empire. Between the 16th and 18th century, the Khanate of Bukhara, Safavids, and Mughals ruled parts of the territory. Before the 19th century, the northwestern area of Afghanistan was referred to by the regional name Khorasan. Two of the four capitals of Khorasan (Herat and Balkh) are now located in Afghanistan, while the regions of Kandahar, Zabulistan, Ghazni, Kabulistan, and Afghanistan formed the frontier between Khorasan and Hindustan. === Hotak dynasty and Durrani Empire === In 1709, Mirwais Hotak, a local Ghilzai tribal leader, successfully rebelled against the Safavids. He defeated Gurgin Khan and made Afghanistan independent. Mirwais died of a natural cause in 1715 and was succeeded by his brother Abdul Aziz, who was soon killed by Mirwais' son Mahmud for treason. Mahmud led the Afghan army in 1722 to the Persian capital of Isfahan, captured the city after the Battle of Gulnabad and proclaimed himself King of Persia. The Afghan dynasty was ousted from Persia by Nader Shah after the 1729 Battle of Damghan. In 1738, Nader Shah and his forces captured Kandahar, the last Hotak stronghold, from Shah Hussain Hotak, at which point the incarcerated 16-year-old Ahmad Shah Durrani was freed and made the commander of an Afghan regiment. Soon after the Persian and Afghan forces invaded India. By 1747, the Afghans chose Durrani as their head of state. Durrani and his Afghan army conquered much of present-day Afghanistan, Pakistan, the Khorasan and Kohistan provinces of Iran, and Delhi in India. He defeated the Indian Maratha Empire, and one of his biggest victories was the 1761 Battle of Panipat. In October 1772, Durrani died of a natural cause and was buried at a site now adjacent to the Shrine of the Cloak in Kandahar. He was succeeded by his son, Timur Shah, who transferred the capital of Afghanistan from Kandahar to Kabul in 1776. After Timur's death in 1793, the Durrani throne passed down to his son Zaman Shah, followed by Mahmud Shah, Shuja Shah and others.The Afghan Empire was under threat in the early 19th century by the Persians in the west and the Sikh Empire in the east. Fateh Khan, leader of the Barakzai tribe, had installed 21 of his brothers in positions of power throughout the empire. After his death, they rebelled and divided up the provinces of the empire between themselves. During this turbulent period, Afghanistan had many temporary rulers until Dost Mohammad Khan declared himself emir in 1826. The Punjab region was lost to Ranjit Singh, who invaded Khyber Pakhtunkhwa and in 1834 captured the city of Peshawar. In 1837, during the Battle of Jamrud near the Khyber Pass, Akbar Khan and the Afghan army failed to capture the Jamrud fort from the Sikh Khalsa Army, but killed Sikh Commander Hari Singh Nalwa, thus ending the Afghan-Sikh Wars. By this time the British were advancing from the east and the first major conflict during "The Great Game" was initiated. === British influence and independent kingdom === In 1838, the British marched into Afghanistan and arrested Dost Mohammad, sent him into exile in India and replaced him with the previous ruler, Shah Shuja. Following an uprising, the 1842 retreat from Kabul of British-Indian forces and the annihilation of Elphinstone's army, and the Battle of Kabul that led to its recapture, the British placed Dost Mohammad Khan back into power and withdrew their military forces from Afghanistan. In 1878, the Second Anglo-Afghan War was fought over perceived Russian influence, Abdur Rahman Khan replaced Ayub Khan, and Britain gained control of Afghanistan's foreign relations as part of the Treaty of Gandamak of 1879. In 1893, Mortimer Durand made Amir Abdur Rahman Khan sign a controversial agreement in which the ethnic Pashtun and Baloch territories were divided by the Durand Line. This was a standard divide and rule policy of the British and would lead to strained relations, especially with the later new state of Pakistan. Shia-dominated Hazarajat and pagan Kafiristan remained politically independent until being conquered by Abdur Rahman Khan in 1891-1896. After the Third Anglo-Afghan War and the signing of the Treaty of Rawalpindi on 19 August 1919, King Amanullah Khan declared Afghanistan a sovereign and fully independent state. He moved to end his country's traditional isolation by establishing diplomatic relations with the international community and, following a 1927–28 tour of Europe and Turkey, introduced several reforms intended to modernize his nation. A key force behind these reforms was Mahmud Tarzi, an ardent supporter of the education of women. He fought for Article 68 of Afghanistan's 1923 constitution, which made elementary education compulsory. The institution of slavery was abolished in 1923. Some of the reforms that were actually put in place, such as the abolition of the traditional burqa for women and the opening of a number of co-educational schools, quickly alienated many tribal and religious leaders. Faced with overwhelming armed opposition, Amanullah Khan was forced to abdicate in January 1929 after Kabul fell to rebel forces led by Habibullah Kalakani. Prince Mohammed Nadir Shah, Amanullah's cousin, in turn defeated and killed Kalakani in November 1929, and was declared King Nadir Shah. He abandoned the reforms of Amanullah Khan in favor of a more gradual approach to modernisation but was assassinated in 1933 by Abdul Khaliq, a fifteen-year-old Hazara student. Mohammed Zahir Shah, Nadir Shah's 19-year-old son, succeeded to the throne and reigned from 1933 to 1973. Until 1946, Zahir Shah ruled with the assistance of his uncle, who held the post of Prime Minister and continued the policies of Nadir Shah. Another of Zahir Shah's uncles, Shah Mahmud Khan, became Prime Minister in 1946 and began an experiment allowing greater political freedom, but reversed the policy when it went further than he expected. He was replaced in 1953 by Mohammed Daoud Khan, the king's cousin and brother-in-law. Daoud Khan sought a closer relationship with the Soviet Union and a more distant one towards Pakistan. The King built close relationships with the Axis powers in the 1930s - but Afghanistan remained neutral and was neither a participant in World War II nor aligned with either power bloc in the Cold War thereafter. However, it was a beneficiary of the latter rivalry as both the Soviet Union and the United States vied for influence by building Afghanistan's main highways, airports, and other vital infrastructure. On per capita basis, Afghanistan received more Soviet development aid than any other country. Afghanistan had therefore good relations with both Cold War enemies. In 1973, while King Zahir Shah was on an official overseas visit, Daoud Khan launched a bloodless coup and became the first President of Afghanistan, abolishing the monarchy. In the meantime, Zulfikar Ali Bhutto got neighboring Pakistan involved in Afghanistan. Some experts suggest that Bhutto paved the way for the April 1978 Saur Revolution. === PDPA coup d'état and Soviet war === In April 1978, the People's Democratic Party of Afghanistan (PDPA) seized power in the Saur Revolution, a coup d'état against then-President Mohammed Daoud Khan. The PDPA declared the establishment of the Democratic Republic of Afghanistan, with its first President named as Nur Muhammad Taraki. Opposition to PDPA reforms, such as its land redistribution policy and modernization of (traditional Islamic) civil and marriage laws, led to unrest which aggravated to rebellion and revolt around October 1978, first in eastern Afghanistan (see Initiation of the insurgency in Afghanistan 1978). That uprising quickly expanded into a civil war waged by guerrilla mujahideen against regime forces countrywide. The Pakistani government provided these rebels with covert training centers, while the Soviet Union sent thousands of military advisers to support the PDPA regime. As early as mid-1979 (see CIA activities in Afghanistan), the United States were supporting Afghan mujahideen and foreign "Afghan Arab" fighters through Pakistan's ISI.Meanwhile, increasing friction between the competing factions of the PDPA — the dominant Khalq and the more moderate Parcham — resulted (in July–August 1979) in the dismissal of Parchami cabinet members and the arrest of Parchami military officers under the pretext of a Parchami coup. In September 1979, President Taraki was assassinated in a coup within the PDPA orchestrated by fellow Khalq member Hafizullah Amin, who assumed the presidency. The Soviet Union was displeased with Amin's government, and decided to intervene and invade the country on 27 December 1979, killing Amin that same day. A Soviet-organized regime, led by Parcham's Babrak Karmal but inclusive of both factions (Parcham and Khalq), filled the vacuum. Soviet troops in more substantial numbers were deployed to stabilize Afghanistan under Karmal, and as a result the Soviets were now directly involved in what had been a domestic war in Afghanistan (of mujahideen against PDPA government), which war from December 1979 until 1989 is therefore also known as the Soviet–Afghan War. The United States, supporting the Afghan mujahideen and foreign "Afghan Arab" fighters since mid-1979 through Pakistan's ISI, and Saudi Arabia, from now on delivered for billions in cash and weapons, including two thousand FIM-92 Stinger surface-to-air missiles, to Pakistan as support for the anti-Soviet mujahideen.The PDPA prohibited usury, declared equality of the sexes, and introduced women to political life. During this war from 1979 until 1989, Soviet forces, their Afghan proxies and rebels killed between 562,000 and 2 million Afghans, and displaced about 6 million people who subsequently fled Afghanistan, mainly to Pakistan and Iran. Many countryside villages were bombed and some cities such as Herat and Kandahar were also damaged from air bombardment. Pakistan's North-West Frontier Province functioned as an organisational and networking base for the anti-Soviet Afghan resistance, with the province's influential Deobandi ulama playing a major supporting role in promoting the 'jihad'. Meanwhile, the central Afghan region of Hazarajat, which in this period was free of Soviet or PDPA government presence, experienced an internal civil war from 1980 to 1984. Faced with mounting international pressure and numerous casualties, the Soviets withdrew from Afghanistan in 1989, but continued to support Afghan President Mohammad Najibullah until 1992. === Proxy and civil war and Islamic jihad 1989–96 === Mujahideen (Islamic resistance) forces in October 1978 (see above) had started a guerrilla or civil war against the PDPA's government of Afghanistan. After the Soviet invasion, December 1979, replacing one PDPA President for another PDPA President, the mujahideen proclaimed to be battling the hostile PDPA "puppet regime". In 1987, Mohammad Najibullah had become Afghan President, and after the Soviet withdrawal in 1989 he was still sponsored by the Soviet Union, and fought by the mujahideen. President Najibullah therefore tried to build support for his government by moving away from socialism to pan-Afghan nationalism, abolishing the one-party state, portraying his government as Islamic, and in 1990 removing all signs of communism.Nevertheless, Najibullah did not win any significant support. In March 1989, two mujahideen groups launched an attack on Jalalabad, instigated by the Pakistani Inter-Services Intelligence (ISI) who wanted to see a mujahideen Islamic government established in Afghanistan, but the attack failed after three months. With the dissolution of the Soviet Union in December 1991 and the ending of Russian support, President Najibullah was left without foreign aid. In March 1991, mujahideen forces attacked and conquered the city of Khost. In March 1992, President Najibullah agreed to step aside and make way for a mujahideen coalition government. Mujahideen leaders came together in Peshawar, Pakistan, to negotiate such a government, but mujahideen Hezbi Islami's leader Gulbuddin Hekmatyar, presumably supported by ISI, refused to meet other leaders. On 16 April 1992, four Afghani government Generals ousted President Najibullah. Little later, Hezbi Islami invaded Kabul. This ignited war in Kabul on 25 April with rivalling groups Jamiat and Junbish in which soon two more mujahideen groups mingled; all groups except Jamiat were supported by an Islamic foreign government (Saudi Arabia, Iran, Uzbekistan) or intelligence agency (Pakistan's ISI). In 1992–95, Kabul was heavily bombarded and considerably destroyed, by Hezbi Islami, Jamiat, Junbish, Hizb-i-Wahdat, and Ittihad; in that period, half a million Kabuli fled to Pakistan. In January–June 1994, 25,000 people died in Kabul due to fighting between an alliance of Dostum's (Junbish) with Hekmatyar's (Hezbi Islami) against Massoud’s (Jamiat) forces. Also other cities turned into battleground. In 1993–95, (sub-)commanders of Jamiat, Junbish, Hezbi Islami and Hizb-i-Wahdat descended to rape, murder and extortion. The Taliban emerged in September 1994 as a movement and militia of Pashtun students (talib) from Islamic madrassas (schools) in Pakistan, pledged to rid Afghanistan of 'warlords and criminals', and soon had military support from Pakistan. In November 1994 the Taliban took control of Kandahar city after forcing local Pashtun leaders who had tolerated complete lawlessness. The Taliban in early 1995 attempted to capture Kabul but were repelled by forces under Massoud. Taliban, having grown stronger, in September 1996 attacked and occupied Kabul after Massoud and Hekmatyar had withdrawn their troops from Kabul. === Taliban Emirate and Northern Alliance === In late September 1996, the Taliban, in control of Kabul and most of Afghanistan, proclaimed their Islamic Emirate of Afghanistan. They imposed a strict form of Sharia, similar to that found in Saudi Arabia. According to Physicians for Human Rights (PHR) in 1998, "no other regime in the world has methodically and violently forced half of its population into virtual house arrest, prohibiting them on pain of physical punishment from showing their faces, seeking medical care without a male escort, or attending school" The brutality of the Taliban's totalitarian regime was comparable to those of Stalin's Russia or the Khmer Rouge rule of Cambodia.After the fall of Kabul to the Taliban, Massoud and Dostum formed the Northern Alliance. The Taliban defeated Dostum's forces during the Battles of Mazar-i-Sharif (1997–98). Pakistan's Chief of Army Staff, Pervez Musharraf, began sending thousands of Pakistanis to help the Taliban defeat the Northern Alliance. From 1996 to 2001, the al-Qaeda network of Osama bin Laden and Ayman al-Zawahiri was also operating inside Afghanistan. This and the fact that around one million Afghans were internally displaced made the United States worry. From 1990 to September 2001, around 400,000 Afghans died in the internal mini-wars.On 9 September 2001, Massoud was assassinated by two Arab suicide attackers in Panjshir province of Afghanistan. Two days later, the September 11 attacks were carried out in the United States. The US government suspected Osama bin Laden as the perpetrator of the attacks, and demanded that the Taliban hand him over. The Taliban offered to hand over Bin Laden to a third country for trial, but not directly to the US. Washington refused that offer. Instead, the US launched the October 2001 Operation Enduring Freedom. The majority of Afghans supported the American invasion of their country. During the initial invasion, US and UK forces bombed al-Qaeda training camps. The United States began working with the Northern Alliance to remove the Taliban from power. === Recent history (2002–present) === In December 2001, after the Taliban government was overthrown, the Afghan Interim Administration under Hamid Karzai was formed, in which process the Taliban were typecast as 'the bad guys' and left out. The International Security Assistance Force (ISAF) was established by the UN Security Council to help assist the Karzai administration and provide basic security. Taliban forces meanwhile began regrouping inside Pakistan, while more coalition troops entered Afghanistan and began rebuilding the war-torn country.Shortly after their fall from power, the Taliban began an insurgency to regain control of Afghanistan. Over the next decade, ISAF and Afghan troops led many offensives against the Taliban, but failed to fully defeat them. Afghanistan remains one of the poorest countries in the world due to a lack of foreign investment, government corruption, and the Taliban insurgency.Meanwhile, the Afghan government was able to build some democratic structures, and the country changed its name to the Islamic Republic of Afghanistan. Attempts were made, often with the support of foreign donor countries, to improve the country's economy, healthcare, education, transport, and agriculture. ISAF forces also began to train the Afghan National Security Forces. In the decade following 2002, over five million Afghans were repatriated, including some who were deported from Western countries.By 2009, a Taliban-led shadow government began to form in parts of the country. In 2010, President Karzai attempted to hold peace negotiations with the Taliban leaders, but the rebel group refused to attend until mid-2015 when the Taliban supreme leader finally decided to back the peace talks.After the May 2011 death of Osama bin Laden in Pakistan, many prominent Afghan figures were assassinated. Afghanistan–Pakistan border skirmishes intensified and many large scale attacks by the Pakistan-based Haqqani Network also took place across Afghanistan. The United States blamed rogue elements within the Pakistani government for the increased attacks.The U.S. government spent tens of billions of dollars on development aid over 15 years and over a trillion dollars on military expenses during the same period. Following the 2014 presidential election President Karzai left power and Ashraf Ghani became President in September 2014. The United States' war in Afghanistan – by then the longest in its history – officially ended on 28 December 2014. However, thousands of US-led NATO troops have remained in the country to train and advise Afghan government forces. The 2001–present war has resulted in over 90,000 direct war-related deaths, which includes insurgents, Afghan civilians and government forces. Over 100,000 have been injured. == Geography == A landlocked mountainous country with plains in the north and southwest, Afghanistan is located within South Asia and Central Asia. It is part of the US-coined Greater Middle East Muslim world, which lies between latitudes 29° N and 39° N, and longitudes 60° E and 75° E. The country's highest point is Noshaq, at 7,492 m (24,580 ft) above sea level. It has a continental climate with harsh winters in the central highlands, the glaciated northeast (around Nuristan), and the Wakhan Corridor, where the average temperature in January is below −15 °C (5 °F), and hot summers in the low-lying areas of the Sistan Basin of the southwest, the Jalalabad basin in the east, and the Turkestan plains along the Amu River in the north, where temperatures average over 35 °C (95 °F) in July. Despite having numerous rivers and reservoirs, large parts of the country are dry. The endorheic Sistan Basin is one of the driest regions in the world. Aside from the usual rainfall, Afghanistan receives snow during the winter in the Hindu Kush and Pamir Mountains, and the melting snow in the spring season enters the rivers, lakes, and streams. However, two-thirds of the country's water flows into the neighboring countries of Iran, Pakistan, and Turkmenistan. The state needs more than US$2 billion to rehabilitate its irrigation systems so that the water is properly managed.The northeastern Hindu Kush mountain range, in and around the Badakhshan Province of Afghanistan, is in a geologically active area where earthquakes may occur almost every year. They can be deadly and destructive sometimes, causing landslides in some parts or avalanches during the winter. The last strong earthquakes were in 1998, which killed about 6,000 people in Badakhshan near Tajikistan. This was followed by the 2002 Hindu Kush earthquakes in which over 150 people were killed and over 1,000 injured. A 2010 earthquake left 11 Afghans dead, over 70 injured, and more than 2,000 houses destroyed. The country's natural resources include: coal, copper, iron ore, lithium, uranium, rare earth elements, chromite, gold, zinc, talc, barite, sulfur, lead, marble, precious and semi-precious stones, natural gas, and petroleum, among other things. In 2010, US and Afghan government officials estimated that untapped mineral deposits located in 2007 by the US Geological Survey are worth at least $1 trillion.At over 652,230 km2 (251,830 sq mi), Afghanistan is the world's 41st largest country, slightly bigger than France and smaller than Burma, about the size of Texas in the United States. It borders Pakistan in the south and east; Iran in the west; Turkmenistan, Uzbekistan, and Tajikistan in the north; and China in the far east. == Demographics == The population of Afghanistan was estimated at 29.2 million in 2017. Of this, 15 million are males and 14.2 million females. About 22% of them are urbanite and the remaining 78% live in rural areas. An additional 3 million or so Afghans are temporarily housed in neighboring Pakistan and Iran, most of whom were born and raised in those two countries. This makes the total Afghan population at around 33,332,025, and its current growth rate is 2.34%. This population is expected to reach 82 million by 2050 if current population trends continue.The only city with over a million residents is its capital, Kabul. Due to a lack of census there is no clear indication of what the largest cities in the country are, with various national and international estimates and without always acknowledging the differentiation of city municipalities and urban areas that go beyond city limits. After Kabul the other five large cities are Kandahar, Herat, Mazar-i-Sharif, Kunduz and Jalalabad. Other major cities include Lashkar Gah, Taloqan, Khost, Sheberghan, and Ghazni. === Ethnic groups === Afghanistan's population is divided into several ethnolinguistic groups, which are listed in the chart below: === Languages === Dari and Pashto are the official languages of Afghanistan; bilingualism is very common. Dari, which is a variety of and mutually intelligible with Persian (and very often called 'Farsi' by some Afghans like in Iran) functions as the lingua franca in Kabul as well as in much of the northern and northwestern parts of the country. Pashto is the native tongue of the Pashtuns, although many of them are also fluent in Dari while some non-Pashtuns are fluent in Pashto. There are a number of smaller regional languages, they include Uzbek, Turkmen, Balochi, Pashayi, and Nuristani. Uzbek, Turkmen, Pashayi, Nuristani, Balochi and Pamiri declared third official in areas where the majority speaks them. A number of Afghans are also fluent in Urdu, English, and other foreign languages. === Religions === Over 99% of the Afghan population is Muslim. According to latest estimates, up to 90% practice Sunni Islam and the remaining 7–15% adhere to Shia Islam.Thousands of Afghan Sikhs and Hindus are also found in the major cities. There was a small Jewish community in Afghanistan who had emigrated to Israel and the United States by the end of the twentieth century; at least one Jew, Zablon Simintov, remained. There is also at least one known Christian, current First Lady of Afghanistan Rula Ghani, apart from Christian foreigners. == Governance == Afghanistan is an Islamic republic consisting of three branches, the executive, legislative, and judicial. The nation is led by President Ashraf Ghani with Abdul Rashid Dostum and Sarwar Danish as vice presidents. Abdullah Abdullah serves as the chief executive officer (CEO). The National Assembly is the legislature, a bicameral body having two chambers, the House of the People and the House of Elders. The Supreme Court is led by Chief Justice Said Yusuf Halem, the former Deputy Minister of Justice for Legal Affairs.According to Transparency International, Afghanistan remains in the top most corrupt countries list. A January 2010 report published by the United Nations Office on Drugs and Crime revealed that bribery consumed an amount equal to 23% of the GDP of the nation. A number of government ministries are believed to be rife with corruption, and while then-President Karzai vowed to tackle the problem in 2009 by stating that "individuals who are involved in corruption will have no place in the government", top government officials were stealing and misusing hundreds of millions of dollars through the Kabul Bank. === Elections and parties === The 2004 Afghan presidential election was relatively peaceful, in which Hamid Karzai won in the first round with 55.4% of the votes. However, the 2009 presidential election was characterized by lack of security, low voter turnout, and widespread electoral fraud. The vote, along with elections for 420 provincial council seats, took place in August 2009, but remained unresolved during a lengthy period of vote counting and fraud investigation. Two months later, under international pressure, a second round run-off vote between Karzai and remaining challenger Abdullah was announced, but a few days later Abdullah announced that he would not participate in 7 November run-off because his demands for changes in the electoral commission had not been met. The next day, officials of the election commission cancelled the run-off and declared Hamid Karzai as President for another five-year term.In the 2005 parliamentary election, among the elected officials were former mujahideen, Islamic fundamentalists, warlords, communists, reformists, and several Taliban associates. In the same period, Afghanistan reached to the 30th highest nation in terms of female representation in the National Assembly. The last parliamentary election was held in September 2010, but due to disputes and investigation of fraud, the swearing-in ceremony took place in late January 2011. The 2014 presidential election ended with Ashraf Ghani winning by 56.44% votes. === Administrative divisions === Afghanistan is administratively divided into 34 provinces (wilayats). Each province is the size of a U.S. county, having a governor and a capital. The country is further divided into nearly 400 provincial districts, each of which normally covers a city or a number of villages. Each district is represented by a district governor. The provincial governors are appointed by the President of Afghanistan and the district governors are selected by the provincial governors. The provincial governors are representatives of the central government in Kabul and are responsible for all administrative and formal issues within their provinces. There are also provincial councils that are elected through direct and general elections for a period of four years. The functions of provincial councils are to take part in provincial development planning and to participate in the monitoring and appraisal of other provincial governance institutions. According to article 140 of the constitution and the presidential decree on electoral law, mayors of cities should be elected through free and direct elections for a four-year term. However, due to huge election costs, mayoral and municipal elections have never been held. Instead, mayors have been appointed by the government. In the capital city of Kabul, the mayor is appointed by the President of Afghanistan. The following is a list of all the 34 provinces in alphabetical order: === Foreign relations and military === Afghanistan became a member of the United Nations in 1946. It enjoys cordial relations with a number of NATO and allied nations, particularly the United States, Canada, United Kingdom, Germany, Australia, and Turkey. In 2012, the United States and Afghanistan signed their Strategic Partnership Agreement in which Afghanistan became a major non-NATO ally. Afghanistan also has friendly diplomatic relations with neighboring China, Iran, Pakistan, Tajikistan, Turkmenistan, and Uzbekistan, including with regional states such as Bangladesh, India, Japan, Kazakhstan, Nepal, Russia, South Korea, the UAE, and so forth. The Afghan Ministry of Foreign Affairs continues to develop diplomatic relations with other countries around the world. The United Nations Assistance Mission in Afghanistan (UNAMA) was established in 2002 in order to help the country recover from the decades of war and neglect. Today, a number of NATO member states deploy about 20,000 troops in Afghanistan as part of the Resolute Support Mission. Its main purpose is to train the Afghan National Security Forces. The Afghan Armed Forces are under the Ministry of Defense, which includes the Afghan Air Force (AAF) and the Afghan National Army (ANA). The Afghan Defense University houses various educational establishments for the Afghan Armed Forces, including the National Military Academy of Afghanistan. === Law enforcement === The National Directorate of Security (NDS) is Afghanistan's domestic intelligence agency, which operates similar to that of the U.S. Department of Homeland Security or UK's Scotland Yard. The Afghan National Police (ANP) is under the Ministry of Interior Affairs and serves as a single law enforcement agency all across the country. The Afghan National Civil Order Police is the main branch of the ANP, which is divided into five Brigades, each commanded by a Brigadier General. These brigades are stationed in Kabul, Gardez, Kandahar, Herat, and Mazar-i-Sharif. There is one Chief of Police in every province. All parts of Afghanistan are considered dangerous due to militant activities and terrorism-related incidents. Kidnapping for ransom and robberies are common in major cities. Every year hundreds of Afghan police are killed in the line of duty. The Afghan Border Police (ABP) is responsible for protecting the nation's airports and borders, especially the disputed Durand Line border, which is often used by terrorists and criminals for their illegal activities. Drugs from Afghanistan are smuggled to neighboring countries by various nationals but mostly by Afghans, Iranians, Pakistanis, Tajikistanis, Turkmenistanis and Uzbekistanis. The Afghan Ministry of Counter Narcotics is responsible for the monitoring and eradication of the illegal drug business. == Economy == Afghanistan's GDP is around $64 billion with an exchange rate of $18.4 billion, and its GDP per capita is $2,000. Despite having $1 trillion or more in mineral deposits, it remains as one of the least developed countries. The country imports over $6 billion worth of goods but exports only $658 million, mainly fruits and nuts. It has less than $1.5 billion in external debt.Agricultural production is the backbone of Afghanistan's economy. The country is known for producing some of the finest pomegranates, grapes, apricots, melons, and several other fresh and dry fruits. It is also known as the world's largest producer of opium. Sources indicate that as much as 11% or more of the nation's economy is derived from the cultivation and sale of opium. While the nation's current account deficit is largely financed with donor money, only a small portion is provided directly to the government budget. The rest is provided to non-budgetary expenditure and donor-designated projects through the United Nations system and non-governmental organizations. The Afghan Ministry of Finance is focusing on improved revenue collection and public sector expenditure discipline. For example, government revenues increased 31% to $1.7 billion from March 2010 to March 2011. Da Afghanistan Bank serves as the central bank of the nation and the "Afghani" (AFN) is the national currency, with an exchange rate of about 60 Afghanis to 1 US dollar. A number of local and foreign banks operate in the country, including the Afghanistan International Bank, New Kabul Bank, Azizi Bank, Pashtany Bank, Standard Chartered Bank, and the First Micro Finance Bank. One of the main drivers for the current economic recovery is the return of over 5 million expatriates, who brought with them fresh energy, entrepreneurship and wealth-creating skills as well as much needed funds to start up businesses. Many Afghans are now involved in construction, which is one of the largest industries in the country. Some of the major national construction projects include the $35 billion New Kabul City next to the capital, the Aino Mena project in Kandahar, and the Ghazi Amanullah Khan Town near Jalalabad. Similar development projects have also begun in Herat, Mazar-e-Sharif, and other cities. An estimated 400,000 people enter the labor market each year.A number of small companies and factories began operating in different parts of the country, which not only provide revenues to the government but also create new jobs. Improvements to the business environment have resulted in more than $1.5 billion in telecom investment and created more than 100,000 jobs since 2003. Afghan rugs are becoming popular again, allowing many carpet dealers around the country to hire more workers. Afghanistan is a member of WTO, SAARC, ECO, and OIC. It holds an observer status in SCO. Foreign Minister Zalmai Rassoul told the media in 2011 that his nation's "goal is to achieve an Afghan economy whose growth is based on trade, private enterprise and investment". Experts believe that this will revolutionize the economy of the region. In June 2012, India advocated for private investments in the resource rich country and the creation of a suitable environment therefor.Telecommunications company Roshan is the largest private employer in the country as of 2014. === Mining === Michael E. O'Hanlon of the Brookings Institution estimated that if Afghanistan generates about $10 billion per year from its mineral deposits, its gross national product would double and provide long-term funding for Afghan security forces and other critical needs. The United States Geological Survey (USGS) estimated in 2006 that northern Afghanistan has an average 2.9 billion (bn) barrels (bbl) of crude oil, 15.7 trillion cubic feet (440 bn m3) of natural gas, and 562 million bbl of natural gas liquids. In 2011, Afghanistan signed an oil exploration contract with China National Petroleum Corporation (CNPC) for the development of three oil fields along the Amu Darya river in the north.The country has significant amounts of lithium, copper, gold, coal, iron ore, and other minerals. The Khanashin carbonatite in Helmand Province contains 1,000,000 metric tons (1,100,000 short tons) of rare earth elements. In 2007, a 30-year lease was granted for the Aynak copper mine to the China Metallurgical Group for $3 billion, making it the biggest foreign investment and private business venture in Afghanistan's history. The state-run Steel Authority of India won the mining rights to develop the huge Hajigak iron ore deposit in central Afghanistan. Government officials estimate that 30% of the country's untapped mineral deposits are worth at least $1 trillion. One official asserted that "this will become the backbone of the Afghan economy" and a Pentagon memo stated that Afghanistan could become the "Saudi Arabia of lithium". In a 2011 news story, the CSM reported, "The United States and other Western nations that have borne the brunt of the cost of the Afghan war have been conspicuously absent from the bidding process on Afghanistan's mineral deposits, leaving it mostly to regional powers." == Transport == === Air === Air transport in Afghanistan is provided by the national carrier, Ariana Afghan Airlines (AAA), and by private companies such as Afghan Jet International, East Horizon Airlines, Kam Air, Pamir Airways, and Safi Airways. Airlines from a number of countries also provide flights in and out of the country. These include Air India, Emirates, Gulf Air, Iran Aseman Airlines, Pakistan International Airlines, and Turkish Airlines. The country has four international airports: Hamid Karzai International Airport (formerly Kabul International Airport), Kandahar International Airport, Herat International Airport, and Mazar-e Sharif International Airport. There are also around a dozen domestic airports with flights to Kabul and other major cities. === Rail === As of 2017, the country has three rail links, one a 75 kilometres (47 mi) line from Mazar-i-Sharif to the Uzbekistan border; a 10 kilometres (6.2 mi) long line from Toraghundi to the Turkmenistan border (where it continues as part of Turkmen Railways); and a short link from Aqina across the Turkmen border to Kerki, which is planned to be extended further across Afghanistan. These lines are used for freight only and there is no passenger service as of yet. A rail line between Khaf, Iran and Herat, western Afghanistan, intended for both freight and passengers, is under construction and due to open by 2018. About 125 kilometres (78 mi) of the line will lie on the Afghan side. There are various proposals for the construction of additional rail lines in the country. === Roads === Traveling by bus in Afghanistan remains dangerous due to militant activities. The buses are usually older model Mercedes-Benz and owned by private companies. Serious traffic accidents are common on Afghan roads and highways, particularly on the Kabul–Kandahar and the Kabul–Jalalabad Road.Newer automobiles have recently become more widely available after the rebuilding of roads and highways. They are imported from the United Arab Emirates through Pakistan and Iran. As of 2012, vehicles more than 10 years old are banned from being imported into the country. The development of the nation's road network is a major boost for the economy due to trade with neighboring countries. Postal services in Afghanistan are provided by the publicly owned Afghan Post and private companies such as FedEx, DHL, and others. == Health == According to the Human Development Index, Afghanistan is the 15th least developed country in the world. The average life expectancy is estimated to be around 60 years. The country's maternal mortality rate is 396 deaths/100,000 live births and its infant mortality rate is 66 to 112.8 deaths in every 1,000 live births. The Ministry of Public Health plans to cut the infant mortality rate to 400 for every 100,000 live births before 2020. The country has more than 3,000 midwives, with an additional 300 to 400 being trained each year.There are over 100 hospitals in Afghanistan, with the most advanced treatments being available in Kabul. The French Medical Institute for Children and Indira Gandhi Children's Hospital in Kabul are the leading children's hospitals in the country. Some of the other main hospitals in Kabul include the Jamhuriat Hospital and the under-construction Jinnah Hospital. In spite of all this, many Afghans travel to Pakistan and India for advanced treatment. It was reported in 2006 that nearly 60% of the Afghan population lives within a two-hour walk of the nearest health facility. Disability rate is also high in Afghanistan due to the decades of war. It was reported recently that about 80,000 people are missing limbs. Non-governmental charities such as Save the Children and Mahboba's Promise assist orphans in association with governmental structures. Demographic and Health Surveys is working with the Indian Institute of Health Management Research and others to conduct a survey in Afghanistan focusing on maternal death, among other things. == Education == Education in Afghanistan includes K–12 and higher education, which is overseen by the Ministry of Education and the Ministry of Higher Education. There are over 16,000 schools in the country and roughly 9 million students. Of this, about 60% are males and 40% females. Over 174,000 students are enrolled in different universities around the country. About 21% of these are females. Former Education Minister Ghulam Farooq Wardak had stated that construction of 8,000 schools is required for the remaining children who are deprived of formal learning.The top universities in Afghanistan are the American University of Afghanistan (AUAF) followed by Kabul University (KU), both of which are located in Kabul. The National Military Academy of Afghanistan, modeled after the United States Military Academy at West Point, is a four-year military development institution dedicated to graduating officers for the Afghan Armed Forces. The Afghan Defense University was constructed near Qargha in Kabul. Major universities outside of Kabul include Kandahar University in the south, Herat University in the northwest, Balkh University and Kunduz University in the north, Nangarhar University and Khost University in the east. The United States is building six faculties of education and five provincial teacher training colleges around the country, two large secondary schools in Kabul, and one school in Jalalabad.The literacy rate of the entire population is 38.2% (males 52% and females 24.2%). In 2010, the United States began establishing a number of Lincoln learning centers in Afghanistan. They are set up to serve as programming platforms offering English language classes, library facilities, programming venues, internet connectivity, and educational and other counseling services. A goal of the program is to reach at least 4,000 Afghan citizens per month per location. The Afghan National Security Forces are provided with mandatory literacy courses. In addition to this, Baghch-e-Simsim (based on the American Sesame Street) serves as a means to attract Afghan children into learning. In 2017, Kazakhstan launched an official development assistance program (ODA) to Afghanistan that involved providing training and education to the Afghan women in Kazakh universities. The project aims to strengthen the economic independence of Afghan women by providing education from Kazakhstan’s top educational institutions in public administration and healthcare. == Culture == Afghanistan is mostly a tribal society with different regions of the country having its own subculture. Their history is traced back to at least the time of the Achaemenid Empire in 500 BCE. In the southern and eastern region, the people live according to the Pashtun culture by following Pashtunwali (Pashtun way). The Pashtuns (and Baloch) are largely connected to the culture of South Asia. The remaining Afghans are culturally Persian and Turkic. Some non-Pashtuns who live in proximity with Pashtuns have adopted Pashtunwali in a process called Pashtunization, while some Pashtuns have been Persianized. Those who have lived in Pakistan and Iran over the last 30 years have been further influenced by the cultures of those neighboring nations. Afghans are regarded with mingled apprehension and condescension, for their high regard for personal honor, for their tribe loyalty and for their readiness to use force to settle disputes. As tribal warfare and internecine feuding has been one of their chief occupations since time immemorial, this individualistic trait has made it difficult for foreigners to conquer them. One writer considers the tribal system to be the best way of organizing large groups of people in a country that is geographically difficult, and in a society that, from a materialistic point of view, has an uncomplicated lifestyle. There are various Afghan tribes, and an estimated 2–3 million nomads.The nation has a complex history that has survived either in its current cultures or in the form of various languages and monuments. However, many of its historic monuments have been damaged in modern times. The two famous Buddhas of Bamiyan were destroyed by the Taliban, who regarded them as idolatrous. Despite that, archaeologists are still finding Buddhist relics in different parts of the country, some of them dating back to the 2nd century. This indicates that Buddhism was widespread in Afghanistan. Other historical places include the cities of Herat, Kandahar, Ghazni, Mazar-i-Sharif, and Zaranj. The Minaret of Jam in the Hari River valley is a UNESCO World Heritage site. A cloak reputedly worn by Islam's prophet Muhammad is kept inside the Shrine of the Cloak in Kandahar, a city founded by Alexander and the first capital of Afghanistan. The citadel of Alexander in the western city of Herat has been renovated in recent years and is a popular attraction for tourists. In the north of the country is the Shrine of Ali, believed by many to be the location where Ali was buried. The National Museum of Afghanistan is located in Kabul. === Media and entertainment === Afghanistan has around 150 radio stations and over 50 television stations, which includes the state-owned RTA TV and various private channels such as TOLO and Shamshad TV. The first Afghan newspaper was published in 1906 and there are hundreds of print outlets today. By the 1920s, Radio Kabul was broadcasting local radio services. Television programs began airing in the early 1970s. Voice of America, BBC, and Radio Free Europe/Radio Liberty (RFE/RL) broadcast in both of Afghanistan's official languages. Since 2002, press restrictions have been gradually relaxed and private media diversified. Freedom of expression and the press is promoted in the 2004 constitution and censorship is banned, although defaming individuals or producing material contrary to the principles of Islam is prohibited. The Afghan government cited the growth in the media sector as one of its achievements. In 2017, Reporters Without Borders ranked Afghanistan 120th in the Press Freedom Index out of 180 countries, a better rating than all its neighbors. According to Freedom of the Press as of 2015, Afghanistan is "partly free", whereas most countries in Asia are "not free". The city of Kabul has been home to many musicians who were masters of both traditional and modern Afghan music. Traditional music is especially popular during the Nowruz (New Year) and National Independence Day celebrations. Ahmad Zahir, Nashenas, Ustad Sarahang, Sarban, Ubaidullah Jan, Farhad Darya, and Naghma are some of the notable Afghan musicians, but there are many others. Afghans have long been accustomed to watching Indian Bollywood films and listening to its filmi songs. Many Bollywood film stars have roots in Afghanistan, including Salman Khan, Saif Ali Khan, Shah Rukh Khan (SRK), Aamir Khan, Feroz Khan, Kader Khan, Naseeruddin Shah, Zarine Khan, Celina Jaitly, and a number of others. Several Bollywood films have been shot inside Afghanistan, including Dharmatma, Khuda Gawah, Escape from Taliban, and Kabul Express. === Communication === Telecommunication services in Afghanistan are provided by Afghan Telecom, Afghan Wireless, Etisalat, MTN Group, and Roshan. The country uses its own space satellite called Afghansat 1, which provides services to millions of phone, internet and television subscribers. By 2001 following years of civil war, telecommunications was virtually a non-existent sector, but by 2016 it had grown to a $2 billion industry, with 22 million mobile phone subscribers and 5 million internet users. The sector employs at least 120,000 people nationwide. === Cuisine === Afghanistan has a wide varying landscape allowing for many different crops. Afghan food is largely based upon cereals like wheat, maize, barley and rice, which are the nation's chief crops. Fresh and dried fruits is the most important part of Afghan diet. Afghanistan is well known for its fine fruits, especially pomegranates, grapes, and its extra-sweet jumbo-size melons. === Poetry === Classic Persian and Pashto poetry are a cherished part of Afghan culture. Thursdays are traditionally "poetry night" in the city of Herat when men, women and children gather and recite both ancient and modern poems. Poetry has always been one of the major educational pillars in the region, to the level that it has integrated itself into culture. Some notable poets include Rumi, Rabi'a Balkhi, Sanai, Jami, Khushal Khan Khattak, Rahman Baba, Khalilullah Khalili, and Parween Pazhwak. === Sports === Afghanistan's sports teams are increasingly celebrating titles at international events. Its basketball team won the first team sports title at the 2010 South Asian Games. Later that year, the country's cricket team followed as it won the 2009–10 ICC Intercontinental Cup. In 2012, the country's 3x3 basketball team won the gold medal at the 2012 Asian Beach Games. In 2013, Afghanistan's football team followed as it won the SAFF Championship. Cricket and association football are the most popular sports in the country. The Afghan national cricket team, which was formed in the last decade, participated in the 2009 ICC World Cup Qualifier, 2010 ICC World Cricket League Division One and the 2010 ICC World Twenty20. It won the ACC Twenty20 Cup in 2007, 2009, 2011 and 2013. The team eventually made it to play in the 2015 Cricket World Cup. The Afghanistan Cricket Board (ACB) is the official governing body of the sport and is headquartered in Kabul. The Alokozay Kabul International Cricket Ground serves as the nation's main cricket stadium. There are a number of other stadiums throughout the country, including the Ghazi Amanullah Khan International Cricket Stadium near Jalalabad. Domestically, cricket is played between teams from different provinces. The Afghanistan national football team has been competing in international football since 1941. The national team plays its home games at the Ghazi Stadium in Kabul, while football in Afghanistan is governed by the Afghanistan Football Federation. The national team has never competed or qualified for the FIFA World Cup, but has recently won an international football trophy in 2013. The country also has a national team in the sport of futsal, a 5-a-side variation of football. Other popular sports in Afghanistan include basketball, volleyball, taekwondo, and bodybuilding. Buzkashi is a traditional sport, mainly among the northern Afghans. It is similar to polo, played by horsemen in two teams, each trying to grab and hold a goat carcass. The Afghan Hound (a type of running dog) originated in Afghanistan and was originally used in hunting. == See also == Bibliography of Afghanistan Index of Afghanistan-related articles Outline of Afghanistan == Notes == == References == == Further reading == Books Articles == External links == Office of the President "Afghanistan".

### Instruction: retrieve labels for this: Albania ( ( listen) a(w)l-BAY-nee-ə; Albanian: Shqipëri/Shqipëria; Gheg Albanian: Shqipni/Shqipnia or Shqypni/Shqypnia), officially the Republic of Albania (Albanian: Republika e Shqipërisë, pronounced [ɾɛpuˈblika ɛ ʃcipəˈɾiːsə]), is a country in Southeastern Europe. The country spans 28,748 square kilometres (11,100 square miles) and had a total population of 3 million people as of 2016. It is a unitary parliamentary constitutional republic with the capital in Tirana, the country's most populous city and main economic and commercial centre. The country's other major cities include Durrës, Vlorë, Sarandë, Shkodër, Berat, Korçë, Gjirokastër and Fier. Albania lies in the southwestern portion of the Balkan Peninsula bordered by Montenegro to the northwest, Kosovo to the northeast, the Republic of Macedonia to the east, and Greece to the south and southeast. Most of the country is mountainous, including the Albanian Alps in the north, the Korab Mountains in the east, the Ceraunian Mountains in the south and the Skanderbeg Mountains in the center. The country's coast touches the Adriatic Sea to the northwest and the Ionian Sea to the southwest including the Albanian Riviera. It is less than 72 km (45 mi) from Italy across the Strait of Otranto that connects the Adriatic to the Ionian. Previously in classical antiquity, Albania has been populated by various Illyrian, Thracian and Greek tribes, as well as several Greek colonies established in the Illyrian coast. In the third century BC, the region was annexed by the Roman Empire and became an integral part of the Roman provinces of Dalmatia, Macedonia and Illyricum. The unified Principality of Arbër emerged in 1190, established by archon Progon in the Krujë, within the Byzantine Empire. In the late thirteenth century, Charles of Anjou conquered the Albanian territories from the Byzantines and established the medieval Kingdom of Albania, extending from Durrës along the coast to Butrint in the south. In the mid-fifteenth century, it was conquered by the Ottomans. The modern nation state of Albania emerged in 1912 following the defeat of the Ottomans in the Balkan Wars. The modern Kingdom of Albania was invaded by Italy in 1939, which formed Greater Albania, before becoming a Nazi German protectorate in 1943. After the defeat of Nazi Germany, a Communist state titled the People's Socialist Republic of Albania was founded under the leadership of Enver Hoxha and the Party of Labour. The country experienced widespread social and political transformations in the communist era, as well as isolation from much of the international community. In the aftermath of the Revolutions of 1991, the Socialist Republic was dissolved and the fourth Republic of Albania was established. Albania is a democratic and developing country with an upper-middle income economy. The tertiary sector dominates the country's economy followed by the secondary and primary sector. Following the end of communism in 1990, the country went through a process of transition from a centralized economy to a market-based economy. It also provides universal health care and free primary and secondary education to its citizens.The country is a member of the United Nations, World Bank, UNESCO, NATO, WTO, COE, OSCE and OIC. It is also an official candidate for membership in the European Union. In addition it is one of the founding members of the Energy Community, including the Organization of the Black Sea Economic Cooperation and Union for the Mediterranean. == Etymology == The term Albania is the medieval Latin name of the country. It may be derived from the Illyrian tribe of Albani (Albanian: Albanët) recorded by Ptolemy, the geographer and astronomer from Alexandria, who drafted a map in 150 AD, which shows the city of Albanopolis located northeast of the city of Durrës. The term may have a continuation in the name of a medieval settlement called Albanon or Arbanon, although it is not certain that this was the same place. In his history written in the 10th century, the Byzantine historian Michael Attaliates was the first to refer to Albanoi as having taken part in a revolt against Constantinople in 1043 and to the Arbanitai as subjects of the Duke of Dyrrachium. During the Middle Ages, the Albanians called their country Arbëri or Arbëni and referred to themselves as Arbëreshë or Arbëneshë.Nowaday, Albanians call their country Shqipëri or Shqipëria. As early as the 17th century the placename Shqipëria and the ethnic demonym Shqiptarë gradually replaced Arbëria and Arbëresh. The two terms are popularly interpreted as "Land of the Eagles" and "Children of the Eagles". == History == === Early history === The first traces of human presence in Albania, dating to the Middle Paleolithic and Upper Paleolithic eras, were found in the village of Xarrë close to Sarandë and Dajti near Tiranë. The objects found in a cave near Xarrë include flint and jasper objects and fossilized animal bones, while those found at Mount Dajt comprise bone and stone tools similar to those of the Aurignacian culture. The Paleolithic finds of Albania show great similarities with objects of the same era found at Crvena Stijena in Montenegro and north-western Greece.Several Bronze Age artefacts from tumulus burials have been unearthed in central and southern Albania that show close connection with sites in south-western Macedonia and Lefkada, Greece. Archaeologists have come to the conclusion that these regions were inhabited from the middle of the third millennium BC by Indo-European people who spoke a Proto-Greek language. A part of this population later moved to Mycenae around 1600 BC and founded the Mycenaean civilisation there. In ancient times, the territory of modern Albania was mainly inhabited by a number of Illyrian tribes. The Illyrian tribes never collectively regarded themselves as 'Illyrians', and it is unlikely that they used any collective nomenclature for themselves. The name Illyrians seems to be the name applied to a specific Illyrian tribe, which was the first to come in contact with the ancient Greeks during the Bronze Age, causing the name Illyrians to be applied pars pro toto to all people of similar language and customs. The territory known as Illyria, corresponding roughly to the area east of the Adriatic sea, extending in the south to the mouth of the Vjosë river. The first account of the Illyrian groups comes from Periplus of the Euxine Sea, an ancient Greek text written in the middle of the 4th century BC. The south was inhabited by the Greek tribe of the Chaonians, whose capital was at Phoenice, while numerous colonies, such as Apollonia, Epidamnos and Amantia, were established by Greek city-states on the coast by the 7th century BC.One of the most powerful tribes that ruled over modern Albania was the Ardiaei. The Ardiaean Kingdom reached its greatest extent under Agron, son of Pleuratus II. Agron extended his rule over other neighboring tribes as well. After Agron's death in 230 BC, his wife Teuta inherited the Ardiaean kingdom. Teuta's forces extended their operations further southward into the Ionian Sea. In 229 BC, Rome declared war on Illyria for extensively plundering Roman ships. The war ended in Illyrian defeat in 227 BC. Teuta was eventually succeeded by Gentius in 181 BC. Gentius clashed with the Romans in 168 BC, initiating the Third Illyrian War. The conflict resulted in Roman conquest of the region by 167 BC. After that the Roman split the region into three administrative divisions. === Middle Ages === When the Roman Empire divided into east and west in the 4th century, Albania remained under the Byzantine control until the late 7th century, when Bulgarians began to overrun parts of the country. During that period, the Balkans including Albania, suffered from the dislocation of the Barbarian Invasions. After the weakening of the Byzantine and the Bulgarian Empire in the 13th century, parts of the country has been captured by the Venetian and Serbian Empire. In general, the invaders destroyed or weakened Roman and Byzantine cultural centers in Albania. The Illyrians are mentioned for the last time in a text from the 7th century AD.The first undisputed mention of Albanians in the historical record is in 1079–1080, in a work by Byzantine historian Michael Attaliates, who referred to the Albanoi as having taken part in a revolt against Constantinople. At this point they are fully Christianized. The first semi-autonomous Albanian polity was formed in 1190, when archon Progon of Kruja established the Principality of Arbanon with the capital in Krujë within the Byzantine Empire. Progon, was succeeded by his sons Gjin and Dhimitri, the latter which attained the height of the realm. Following the death of Dhimiter, the last member of the Progon family, the principality came under the Albanian-Greek Gregory Kamonas and later Golem of Kruja. In the 13th century, the principality was dissolved. Arbanon is considered to be the first sketch of an Albanian state, that retained a semi-autonomous status as the western extremity of the Byzantine Empire, under the Byzantine Doukai of Epirus or Laskarids of Nicaea. Few years after the dissolution of Arbanon, Charles of Anjou concluded an agreement with the Albanian rulers, promising to protect them and their ancient liberties. In 1272, he established the Kingdom of Albania and conquered regions back from the Despotate of Epirus. The kingdom claimed all of central Albania territory from Dyrrhachium along the Adriatic Sea Coast down to Butrint. A catholic political structure was a basis for the papal plans of spreading Catholicism in the Balkan Peninsula. This plan found also the support of Helen of Anjou, a cousin of Charles of Anjou, who was at that time ruling territories in North Albania. Around 30 Catholic churches and monasteries were built during her rule mainly in Northern Albania. From 1331 to 1355, the Serbian Empire wrestled control over Albania. In 1367, various Albanian rulers established the Despotate of Arta. During that time, several Albanian principalities were created, most notable amongst them the Balsha, Thopia, Kastrioti, Muzaka and Arianiti. In the first half of the 14th century, the Ottoman Empire invaded most of Albania and the League of Lezhë was held under Skanderbeg as a ruler, who became the national hero of the Albanian medieval history. At the dawn of the establishment of the Ottoman Empire in southeastern Europe, the geopolitical landscape was marked by scattered kingdoms of small principalities. The Ottomans erected their garrisons throughout southern Albania in 1415 and occupied most of the country in 1431. However, in 1443 a great and longstanding revolt broke out under the lead of the Albanian national hero George Castrioti Skanderbeg (Gjergj Kastrioti Skënderbeu), which lasted until 1479, many times defeating major Ottoman armies led by the sultans Murad II and Mehmed II. Skanderbeg united initially the Albanian princes, and later on established a centralized authority over most of the non-conquered territories, becoming the ruling Lord of Albania. He also tried relentlessly but rather unsuccessfully to create a European coalition against the Ottomans. He thwarted every attempt by the Turks to regain Albania, which they envisioned as a springboard for the invasion of Italy and western Europe. His unequal fight against the mightiest power of the time, won the esteem of Europe as well as some support in the form of money and military aid from Naples, Venice, Ragusa and the Papacy. With the arrival of the Ottomans, Islam was introduced in the country as a third religion. This conversion caused a massive emigration of Albanians to other Christian European countries, especially the Arbëreshë of Italy. As Muslims, some Albanians attained important political and military positions within the Ottoman Empire and culturally contributed to the wider Muslim world. Enjoying this privileged position in the empire, Muslim Albanians held various high administrative positions, with over two dozen Grand Viziers of Albanian origin, such as Gen. Köprülü Mehmed Pasha, who commanded the Ottoman forces during the Ottoman-Persian Wars; Gen. Köprülü Fazıl Ahmed, who led the Ottoman armies during the Austro-Turkish War; and later Muhammad Ali Pasha of Egypt.During the 15th century, when the Ottomans were gaining a firm foothold in the region, Albanian towns were organised into four principal sanjaks. The government fostered trade by settling a sizeable Jewish colony of refugees fleeing persecution in Spain (at the end of the 15th century). The city of Vlorë saw passing through its ports imported merchandise from Europe such as velvets, cotton goods, mohairs, carpets, spices, and leather from Bursa and Constantinople. Some citizens of Vlorë even had business associates throughout Europe.Albanians could also be found throughout the empire in Iraq, Egypt, Algeria and across the Maghreb, as vital military and administrative retainers. This was partly due to the Devşirme system. The process of Islamization was an incremental one, commencing from the arrival of the Ottomans in the 14th century (to this day, a minority of Albanians are Catholic or Orthodox Christians, though the majority became Muslim). Timar holders, the bedrock of early Ottoman control in southeast Europe, were not necessarily converts to Islam, and occasionally rebelled; the most famous of these rebels is Skanderbeg (his figure would rise up later on, in the 19th century, as a central component of the Albanian national identity). The most significant impact on the Albanians was the gradual Islamisation process of a large majority of the population, although it became widespread only in the 17th century.Mainly Catholics converted in the 17th century, while the Orthodox Albanians followed suit mainly in the following century. Initially confined to the main city centres of Elbasan and Shkodër, by this period the countryside was also embracing the new religion. The motives for conversion according to some scholars were diverse, depending on the context. The lack of source material does not help when investigating such issues. Albania remained under Ottoman control as part of the Rumelia province until 1912, when the independence of the country was proclaimed. === Modern === The National Renaissance (Rilindja Kombëtare) began in the 1870s and lasted until 1912, when the Albanians declared their independence. The League of Prizren (League for the Defense of the Rights of the Albanian Nation) (Lidhja e Prizrenit) was formed in June 1878, in the old town of Prizren, Kosovo Vilayet. At first the Ottoman authorities supported the League, whose initial position was based on the religious solidarity of Muslim landlords and people connected with the Ottoman administration. The Ottomans favoured and protected the Muslim solidarity, and called for defense of Muslim lands, including present-day Bosnia and Herzegovina. This was the reason for naming the league 'The Committee of the Real Muslims' (Komiteti i Myslimanëve të Vërtetë). The League issued a decree known as Kararname. Its text contained a proclamation that the people from northern Albania, Epirus and Bosnia" are willing to defend the 'territorial integrity' of the Ottoman Empire by all possible means against the troops of the Bulgarian, Serbian and Montenegrin Kingdoms. However, it was signed by 47 Muslim deputies of the League on June 18, 1878. Around 300 Muslims participated in the assembly, including delegates from Bosnia and mutasarrif (sanjakbey) of the Sanjak of Prizren as representatives of the central authorities, and no delegates from Scutari Vilayet. The Ottomans cancelled their support when the League, under the influence of Abdyl Bey Frashëri, became focused on working toward the Albanian autonomy and requested merging of four Ottoman vilayets, which includes Kosovo, Scutari, Monastir and Ioannina into a new vilayet of the Ottoman Empire, the Albanian Vilayet. The League used military force to prevent the annexing areas of Plav and Gusinje assigned to Montenegro by the Congress of Berlin. After several successful battles with Montenegrin troops such as in Novsice, under the pressure of the great powers, the League of Prizren was forced to retreat from their contested regions of Plav and Gusinje and later on, the league was defeated by the Ottoman army sent by the Sultan. The Albanian uprising of 1912, the Ottoman defeat in the Balkan Wars and the advance of Montenegrin, Serbian and Greek forces into territories claimed as Albanian, led to the proclamation of independence by Ismail Qemali in southern Vlorë, on November 28, 1912. At the All-Albanian Congress in southern Vlorë on 28 November 1912, the participants constituted the Assembly of Vlorë. The assembly of eighty-three leaders, declared the nation as an independent country and set up a provisional government. The Provisional Government was established on the second session of the assembly on 4 December 1912. Furthermore, it was a government of ten members led by Ismail Qemali, until his resignation on 22 January 1914. However the Assembly also established the Senate (Pleqësi), with an advisory role to the government, consisting of 18 members of the Assembly.The independence of Albania was recognized by the Conference of London on 29 July 1913. The drawing of the borders of the newly established Principality of Albania ignored the demographic realities of the time. The International Commission of Control was established on 15 October 1913 to take care of the administration of newly established Albania, until its own political institutions were in order. Its headquarters were in Vlorë. The International Gendarmerie was established as the first law enforcement agency of the Principality of Albania. In November, the first gendarmerie members arrived in the country. Prince of Albania Wilhelm of Wied (Princ Vilhelm Vidi) was selected as the first prince of the principality. On 7 March, he arrived in the provisional capital of Durrës and started to organise his government, appointing Turhan Pasha Përmeti to form the first Albanian cabinet. In November 1913, the Albanian pro-Ottoman forces had offered the throne of Albania to the Ottoman war Minister of Albanian origin, Ahmed Izzet Pasha. The pro-Ottoman peasants believed that, the new regime of the Principality of Albania was a tool of the six Christian Great Powers and local landowners, that owned half of the arable land.In February 1914, the Autonomous Republic of Northern Epirus was proclaimed in Gjirokastër by the local Greek population against incorporation to Albania. This initiative was short lived and in 1921, the southern provinces were finally incorporated to the Albanian Principality. Meanwhile, the revolt of Albanian peasants against the new Albanian regime erupted under the leadership of the group of Muslim clerics gathered around Essad Pasha Toptani, who proclaimed himself the savior of Albania and Islam. In order to gain support of the Mirdita Catholic volunteers from the northern part of Albania, Prince Wied appointed their leader, Prênk Bibë Doda, to be the foreign minister of the Principality of Albania. In May and June 1914, the International Gendarmerie was joined by Isa Boletini and his men, mostly from Kosovo, and northern Mirdita Catholics, were defeated by the rebels who captured most of Central Albania by the end of August 1914. The regime of Prince Wied collapsed and later he left the country on 3 September 1914. === First Republic === The short-lived principality (1914–1925) was succeeded by the first Albanian Republic (1925–1928). In 1925 the four-member Regency was abolished and Ahmed Zogu was elected president of the newly declared republic. Tirana was endorsed officially as the country's permanent capital. Zogu led an authoritarian and conservative regime, the primary aim of which was the maintenance of stability and order. Zogu was forced to adopt a policy of cooperation with Italy. A pact had been signed between Italy and Albania on 20 January 1925 whereby Italy gained a monopoly on shipping and trade concessions.The Albanian republic was eventually replaced by another monarchy in 1928. In order to extend his direct control throughout the entire country, Zogu placed great emphasis on the construction of roads. Every male Albanian over the age of 16 years was legally bound to give ten days of free labor each year to the state. King Zogu remained a conservative, but initiated reforms. For example, in an attempt at social modernization, the custom of adding one's region to one's name was dropped. Zogu also made donations of land to international organisations for the building of schools and hospitals. The armed forces were trained and supervised by Italian instructors. As a counterweight, Zogu kept British officers in the Gendarmerie despite strong Italian pressure to remove them. The kingdom was supported by the fascist regime in Italy and the two countries maintained close relations until Italy's sudden invasion of the country in 1939. Albania was occupied by Fascist Italy and then by Nazi Germany during World War II. After being militarily occupied by Italy, from 1939 until 1943 the Albanian Kingdom was a protectorate and a dependency of Italy governed by the Italian King Victor Emmanuel III and his government. After the Axis' invasion of Yugoslavia in April 1941, territories of Yugoslavia with substantial Albanian population were annexed to Albania: most of Kosovo, as well as Western Macedonia, the town of Tutin in Central Serbia and a strip of Eastern Montenegro. In November 1941, the small Albanian Communist groups established an Albanian Communist Party in Tirana of 130 members under the leadership of Enver Hoxha and an eleven-man Central Committee. The party at first had little mass appeal, and even its youth organization netted few recruits. After the capitulation of Italy in 1943, Nazi Germany occupied Albania too. The nationalist Balli Kombetar, which had fought against Italy, formed a "neutral" government in Tirana, and side by side with the Germans fought against the communist-led National Liberation Movement of Albania. The Center for Relief to Civilian Populations (Geneva) reported that Albania was one of the most devastated countries in Europe. 60,000 houses were destroyed and about 10% of the population was left homeless. The communist partisans had regrouped and gained control of much of southern Albania in January 1944. However, they were subject to German attacks driving them out of certain areas. In the Congress of Përmet, the NLF formed an Anti-Fascist Council of National Liberation to act as Albania's administration and legislature. By the last year in World War II Albania fell into a civil war-like state between the communists and nationalists. The communist partisans however defeated the last Balli Kombëtar forces in southern Albania by mid-summer 1944. Before the end of November, the main German troops had withdrawn from Tirana, and the communists took control by attacking it. The partisans entirely liberated Albania from German occupation on 29 November 1944. A provisional government, which the communists had formed at Berat in October, administered Albania with Enver Hoxha as prime minister. === Communism === By the end of the Second World War, the main military and political force of the nation, the Communist party sent forces to northern Albania against the nationalists to eliminate its rivals. They faced open resistance in Nikaj-Mërtur, Dukagjin and Kelmend led by Prek Cali. On 15 January 1945, a clash took place between partisans of the first Brigade and nationalist forces at the Tamara Bridge, resulting in the defeat of the nationalist forces. About 150 Kelmendi people were killed or tortured. This event was the starting point of many other issues which took place during Enver Hoxha's dictatorship. Class struggle was strictly applied, human freedom and human rights were denied. The Kelmend region was almost isolated by both the border and by a lack of roads for another 20 years, the institution of agricultural cooperatives brought about economic decline. Many Kelmendi people fled, some were executed trying to cross the border.After the liberation of Albania from the Nazi occupation, the country became a Communist state. Afterwards, the People's Republic of Albania (renamed "People's Socialist Republic of Albania" in 1976) was founded, which was led by Enver Hoxha and the Labour Party of Albania. The socialist reconstruction of Albania was launched immediately after the annulling of the monarchy and the establishment of a People's Republic. In 1947, Albania's first railway line was completed, with the second one being completed eight months later. New land reform laws were passed granting ownership of the land to the workers and peasants who tilled it. Agriculture became cooperative, and production increased significantly, leading to Albania's becoming agriculturally self-sufficient. By 1955, illiteracy was eliminated among Albania's adult population. During this period, Albania became industrialized and saw rapid economic growth, as well as unprecedented progress in the areas of education and health care. The average annual increase in Albania's national income was 29% higher than the world average and 56% higher than the European average.. The nation incurred large debts, first with Yugoslavia until 1948, then the Soviet Union until 1961, and China from the middle of the 1950s. The communist constitution did not allow taxes on individuals; instead, taxes were imposed on cooperatives and other organizations, with much the same effect.Religious freedoms were severely curtailed during the communist regime, with all forms of worship being outlawed. In August 1945, the Agrarian Reform Law meant that large swaths of property owned by religious groups (mostly Islamic waqfs) were nationalized, along with the estates of monasteries and dioceses. Many believers, along with the ulema and many priests, were arrested and executed. In 1949, a new Decree on Religious Communities required that all their activities be sanctioned by the state alone.After hundreds of mosques and dozens of Islamic libraries, containing priceless manuscripts, were destroyed, Enver Hoxha proclaimed Albania the "World's first atheist state" in 1967. The churches had not been spared either, and many were converted into cultural centers for young people. A 1967 law banned all "fascist, religious, warmongerish, antisocialist activity and propaganda". Preaching religion carried a three to ten-year prison sentence. Nonetheless, many Albanians continued to practice their beliefs secretly. The Hoxha dictatorship's anti-religious policy attained its most fundamental legal and political expression a decade later: "The state recognizes no religion," states Albania's 1976 constitution, "and supports and carries out atheistic propaganda in order to implant a scientific materialistic world outlook in people." Enver Hoxha's political successor, Ramiz Alia oversaw the dismemberment of the "Hoxhaist" state during the collapse of the Eastern Bloc in the late 1980s. === Fourth Republic === After the revolution of 1989, reforms were made by the communist government in 1990. Subsequently, the People's Republic was dissolved and the 4th Albanian Republic was founded on 29 April 1991. The communists retained a stronghold in the Parliament, after popular support in the first multi-party elections in 1991. In March 1992, amid liberalization policies resulting in economic collapse and social unrest, a new coalition led by the new Democratic Party took power after victory in the parliamentary elections of 1992. In the following years, much of the accumulated wealth of the country was invested in Ponzi pyramid banking schemes, which were widely supported by the government. The schemes swept up somewhere between one sixth and one third of the Albanian population. Despite the International Monetary Fund (IMF) warnings in late 1996, President Sali Berisha defended the schemes as large investment firms, leading more people to redirect their remittances and sell their homes and cattle for cash to deposit in the schemes. The schemes began to collapse in late 1996, leading many of the investors to join initially peaceful protests against the government, requesting their money back. The protests turned violent in February 1997 as government forces responded with fire. In March, the Police and Republican Guard deserted, leaving their armories open. These were promptly emptied by militias and criminal gangs. The resulting crisis caused a wave of evacuations of foreign nationals and of refugees.The crisis led Prime Minister Aleksandër Meksi to resign on 11 March 1997, followed by President Sali Berisha in July in the wake of the June General Election. In April 1997, Operation Alba, a UN peacekeeping force led by Italy, entered the country with two goals: to assist with the evacuation of expatriates and to secure the ground for international organizations. The main international organization involved was the Western European Union's Multinational Albanian Police element (MAPE), which worked with the government to restructure the judicial system and the Albanian Police. The Socialist Party had won the previously mentioned parliamentary elections in June 1997, and a degree of political stabilization followed. In 1999, the country was affected by the Kosovo War, which caused a great number of ethnic Albanians from Kosovo to seek refuge in Albania, although most ultimately returned to Kosovo. On 23 June 2013, the eighth parliamentary elections took place, won by Edi Rama of the Socialist Party. During his tenure as 33rd Prime Minister, Albania has implemented numerous reforms focused on the modernizing the economy and democratizing of state institutions like the judiciary and law enforcement. Additionally, unemployment has been steadily reduced to the 4th lowest unemployment rate in the Balkans.After the collapse of the Eastern Bloc, Albania started to develop closer ties with Western Europe. At the 2008 Bucharest summit, the North Atlantic Treaty Organization (NATO) invited Albania to join the alliance. In April 2014 Albania became a full member of NATO. Albania was among the first southeastern European countries to join the Partnership for peace programme. Albania applied to join the European Union, becoming an official candidate for accession to the European Union in June 2014. Although Albania received candidate status for the European Union membership in 2014 (based on its 2009 application), the European Union has twice rejected full membership. The European Parliament warned the Government leaders in early 2017 that the 2017 parliamentary elections in June must be free and fair before negotiations could begin to admit the country into the union. == Geography == Albania occupies the southwestern portion of the Balkan Peninsula. The country is located in Southeastern and Southern Europe, with Montenegro bordering to the northwest, Kosovo to the northeast, Macedonia to the east and Greece to the south. The Mediterranean Sea make up the entire west border of Albania. The country lies mostly between latitudes 42° and 39° N, and longitudes 21° and 19° E. Its territory covers 28,748 square kilometres (11,100 square miles). By territory, Albania is the 14th largest country in the mediterranean and the 145th largest country in the world. It's coastline length is 476 km (296 mi) and extends along the Adriatic and Ionian Seas, both within the Mediterranean Sea.Albania's northernmost point is Vërmosh at 42° 35' 34" northern latitude; the southernmost is Konispol at 39° 40' 0" northern latitude; the westernmost point is Sazan Island at 19° 16' 50" eastern longitude; and the easternmost point is Vërnik at 21° 1' 26" eastern longitude. The highest natural point is Mount Korab, standing at 2,764 metres (9,068.24 ft) above the Adriatic. The lowest natural point is the Adriatic Sea, at 0 metres (0.00 ft). The distance from east to west is 148 kilometres (92 mi), from north to south 340 kilometres (211 mi). Despite its small size, Albania is dominated by mountainous or high terrain, with a wide variety of natural features including valleys, plains, canyons and caves. Topographically, the mountains run the length of the country from north to south; the Albanian Alps in the north, Sharr Mountains in the northeast, Skanderbeg Mountains in the center, Korab Mountains in the east, Pindus Mountains in the southeast and the Ceraunian Mountains in the southwest along the Albanian Riviera. The hydrographic network of Albania includes several of the largest and most ancient bodies of fresh water in Southern Europe. Lake Shkodër is the largest lake, situated in the northwest with a surface which can vary between 370 km2 (140 sq mi) and 530 km2 (200 sq mi), out of which one third belongs to Albania and the rest to Montenegro. It is the largest lake in Southern Europe. Lake Ohrid in the southeast is shared with Macedonia and is one of the most ancient lakes in the world. Lake Prespa at the border triangle with Macedonia and Greece is one of the highest tectonic lakes within the Balkan Peninsula at 853 metres (2,799 ft) above the Adriatic. === Climate === Albania comprises a wide range of climatic conditions across its small territory and varied topography, although most of the country experiences mediterranean climate, characterised by mild winters and hot, dry summers. As defined by the Köppen climate classification, the country hosts five major climatic subtypes, including mediterranean, subtropical, oceanic, continental and subarctic. Between the north and south, the west and east there can be a considerable difference in climate.In general, northern parts of the country are characterized by cold winters and cool summers, while the southern parts by predominantly mild wet winters and very hot, dry summers. The highest temperature of 43.9 °C (111.0 °F) was recorded in Kuçovë on 18 July 1973 and the lowest temperature of −29 °C (−20 °F) was registered in the village of Shtyllë, Librazhd on 9 January 2017.The climate in the lowlands is typically mediterranean, while in the hinterlands it is continental. The warmest areas of the country are at the Adriatic and Ionian coast in the lowlands, where climate is profoundly affected by the sea. The coldest parts of the country are at the northern and eastern hinterlands, where snowy forested climate is prevalent in the areas above 1,500 metres (4,900 feet) above the Adriatic. Temperature is affected more by differences in longitude than by latitude or any other factor. Average summer temperatures are lower in the hinterlands than in the lowlands, but daily fluctuations are greater. The mean monthly temperature ranges between −1 °C (30 °F) in winter and 21.8 °C (71.2 °F) in summer. The average precipitation in Albania is about 1,485 millimetres (58.5 inches). The country receives most of the precipitation during winter months and less during summer months. The mean annual precipitation ranges between 600 millimetres (24 inches) and 3,000 millimetres (120 inches) depending on geographic region. Due to the high altitude, the northwestern and southeastern hinterlands receives the higher amount of precipitation, while the northeastern, southwestern hinterlands and western lowlands the smaller amount of precipitation. The Albanian Alps are considered among the wettest areas in Europe, receiving 3,100 mm (122.0 in) of rain annually. An expedition from the University of Colorado discovered four small glaciers inside the Albanian Alps. The glaciers are at the relatively low level of 2,000 metres (6,600 ft), almost unique for such a southerly latitude.Snow falls regularly in winter in the interior of the country, particularly on the mountains in the north and east, including the Albanian Alps and Korab Mountains. Moreover, snow also falls on the coastal areas in the southwest almost every winter such as in the Ceraunian Mountains, where it can lie even beyond March. === Biodiversity === Even though small in size, Albania is distinguished by exceptionally rich and varied biodiversity. The country is host to 30% of the entire flora and 42% of fauna of Europe. Phytogeographically, Albania straddles the Illyrian province of the Circumboreal Region within the Boreal Kingdom. The country falls within four terrestrial ecoregions of the Palearctic ecozone including the Illyrian deciduous forests, Balkan mixed forests, Pindus Mountains mixed forests and Dinaric Alpine mixed forests. The country's biodiversity is conserved in 14 national parks, 1 marine park, 4 ramsar sites, 1 biosphere reserve, 45 important plant areas, 16 important bird areas and 786 protected areas of various caterogies. Albania has about 4,312 square kilometres (1,665 square miles) of pasture land and 10,000 square kilometres (3,861 square miles) of forest land, which is characteristically rich in flora. About 3,000 different species of plants can be found in the country, many of which are often used for medicinal purposes. The coastal regions and lowlands have typical Mediterranean macchia vegetation, whereas oak forests and vegetation are found at higher elevations. Vast forests of pine, beech and fir are found on higher mountains such as in the Albanian Alps and Korab Mountains. Alpine grasslands grow at elevations above 1,800 metres (5,900 feet). About 58 species of mammal and 353 species of birds occur in the country. Gray wolves, red foxes, brown bears, wild boars and chamoises are few of the primary large mammals. Lynxes, wildcats, pine martens and polecats are rare, but still survive distributed throughout the country. Some of the most significant bird species found in the country include various bird of prey, vulture, grouse and waterfowl species. The golden eagle is both the national animal and national symbol of Albania. There are some 91 globally threatened species found within the country, most notable amongst them the dalmatian pelican, pygmy cormorant and european sea sturgeon. The rocky coastal regions in the south provide good habitats for the endangered mediterranean monk seal and short-beaked common dolphin. Albania had an outstanding performance in the 2010 Environmental Performance Index, ranking 23th out of 163 countries in the world. In 2012, the country advanced from 23th to 15th, whereas it had the highest ranking in South and Eastern Europe and Central Asia. The country was the 24th greenest country in the world according to the 2005 Environmental Sustainability Index. Nevertheless, for 2016, the country was ranked the 13th best performing country on the Happy Planet Index by the United Nations. == Administrative divisions == Albania is a unitary state. Spanning a total surface area of 28,748 square kilometres (11,100 square miles), the country is divided into 12 counties with their own council and administration. The counties are the country's primary administrative divisions and further subdivided into 61 municipalities. They are responsible for geographical, economic, social and cultural purposes inside the counties. Until 2000, the 12 counties were subdivided into 36 districts. The counties were created on 31 July 2000 to replace the 36 former districts. The government introduced the new administrative divisions to be implemented in 2015, whereby municipalities were reduced to 61, while the rurals were abolished. The defunct municipalities are known as neighborhoods or villages. There are overall 2980 villages or communities in the entire country, formerly known as localities. The municipalities are the first level of local governance, responsible for local needs and law enforcement.The largest county in the country by population is Tirana with over 800,000 people, followed by Fier with over 300,000 people. The smallest county by population is Gjirokastër with over 70,000 people. The largest in the county by area is Korçë, encompassing 3,711 square kilometres (1,433 sq mi) in the southeast, followed by Shkodër 3,562 square kilometres (1,375 sq mi) in the northwest. The smallest county by area is Durrës with an surface area of 766 square kilometres (296 sq mi) in the west. == Politics == The politics in the country operate under a framework laid out in the Constitution of Albania. First in 1913, Albania was constituted as a monarchy, briefly a republic in 1920, then into a democratic monarchy in 1928. Succeeding, it became a socialist republic, until the restoration of capitalism and democracy, after the end of communism. Nowadays, Albania is a unitary parliamentary constitutional republic in which the president serves as the head of state and the prime minister as the head of government.The president is the head of state, commander-in-chief of the military and the representative of the unity of the Albanian people. The head of state is elected to a five-year term by the parliament by a majority of three-fifths of all its members. The president has the power to guarantee observation of the constitution and all laws, exercise the duties of the parliament when it is not in session and appoints the prime minister. The executive power is exercised by the head of government and the council of ministers, which make up the government. The parliament must give final approval of the composition of the cabinet. The prime minister is responsible for carrying out both foreign and domestic policies, directs and controls the activities of the ministries and other state organs. The parliament is the unicameral representative body of the citizens of Albania and is elected by the people to a four-year term on the basis of direct, universal, periodic and equal suffrage by secret ballot. There are 140 deputies in the parliament, which are elected through a party-list proportional representation system. The parliament has the power to decide the direction of domestic and foreign policy, approve or amend the constitution, declare war on another state, ratify or annul international treaties, elect the president, the supreme court, the attorney general and their deputies and control the activity of state radio and television, state news agency and other official information media. The judicial system of Albania is a civil law system divided between courts with regular civil and criminal jurisdiction and administrative courts. It is codified and based on the French law. Major institutions of the branch include the supreme court, constitutional court, court of appeal, and the administrative court. Law enforcement in the country is primarily the responsibility of the Albanian Police. It is the main and largest state law enforcement agency in the country. It carries out nearly all general police duties including criminal investigation, patrol activity, traffic policing and border control. === Foreign relations === Foreign relations are conducted through the Ministry of Foreign Affairs in Tirana. The current minister is Ditmir Bushati. Since the collapse of Communism in 1990, Albania has extended its responsibilities and position in European and international affairs, supporting and establishing friendly relations with other nations around the world. The main objectives of the Albanian foreign policy are the Accession of Albania to the European Union, the International recognition of Kosovo, the recognition of Expulsion of Cham Albanians, helping and protecting of the rights the Albanians in Montenegro, Macedonia, Greece, southern Serbia, Italy and the Albanian diaspora. Albania has a network of 40 foreign embassies and 46 diplomatic missions abroad. Albania has been a member of the United Nations since December 1955. Three years later in 1958, it became member of UNESCO. Albania took on the membership of the United Nations Economic and Social Council from 2005 to 2007 and for the second time in 2012. In addition to that, Albania served as vice president of the ECOSOC in 2006 and 2013. In 2014, it also joined the United Nations Human Rights Council from 2015 to 2017 and was elected vice president in 2015. Albania was among the first eastern European countries to join the North Atlantic Treaty Organization (NATO). Major Albanian politicians considered admission to NATO as a top priority for the country. Since 1992, it has been extensively engaged with NATO, and has maintained its position as a stability factor and a strong ally of the United States and European Union in the troubled and divided region of the Balkans. Besides, Albania is a full member of numerous international organizations, namely the United Nations, Council of Europe, International Organization for Migration, World Health Organization, Union for the Mediterranean, Organisation of Islamic Cooperation, Organization for Security and Cooperation in Europe, International Monetary Fund, World Trade Organization and La Francophonie. === Military === The Albanian Armed Forces are the military and paramilitary forces of Albania, under the President as supreme commander. In times of peace, the President's powers as a commander are executed through the Prime Minister and the Defence Minister. The military consists of the General staff, Land Force, Air Force and the Naval Force. Albania has nocompulsory military service. Until January 2010 military service was compulsory for men at age 18 and conscripts served six-month tours of duty. Nowadays, military service is voluntary, with the age of 19 being the legal minimum age for the duty.Albania has committed to increase the participations in multinational operations. Since the fall of communism, the country has participated in six international missions but participated in only one United Nations mission in Georgia sending of 3 military observers. Since February 2008, Albania has participated officially in NATO's Operation Active Endeavor in the Mediterranean Sea. It was invited to join NATO on 3 April 2008, and it became a full member on 2 April 2009.Albania reduced the number of active troops from 65,000 in 1988 to 14,500 in 2009. The military now consists mainly of a small fleet of aircraft and sea vessels. In the 1990s, the country scrapped enormous amounts of obsolete hardware from China, such as tanks and SAM systems. Increasing the military budget was one of the most important conditions for NATO integration. Military spending has generally been low. As of 1996 military spending was an estimated 1.5% of the country's GDP, only to peak in 2009 at 2% and fall again to 1.5%. According to 2016 Global Peace Index, the nation ranked 54th out of 163 countries in the world. == Economy == The transition from a socialist planned economy to a capitalist mixed economy has been largely successful. Albania has a developing mixed economy that is classed as an upper-middle income economy by the World Bank. With 14.7% in 2016, Albania has the 4th lowest unemployment rate in the Balkans. Albania's largest trading partners are Italy, Greece, China, Spain, Kosovo and the United States. The lek (ALL) is Albania's currency and is pegged at approximately 132,51 lek per euro. Tirana and Durrës are the economic heart of Albania. Further, Tirana is the major centre for trade, banking and finance, transportation, advertising, legal services, accountancy, and insurance. Major roads and railways run through Tirana and Durrës, connecting the north with the south and the west with the east. Among the largest companies the petroleum Taçi Oil, Albpetrol, ARMO and Kastrati, the mineral AlbChrome, the cement Antea, the investment BALFIN Group and the technology Albtelecom, Vodafone, Telekom Albania and others. In 2012, Albania's GDP per capita stood at 30% of the European Union average, while GDP (PPP) per capita was 35%. Albania were one of three countries in Europe to record an economic growth in the first quarter of 2010 after the global financial crisis. The International Monetary Fund predicted 2.6% growth for Albania in 2010 and 3.2% in 2011. According to the Forbes as of December 2016, the Gross Domestic Product (GDP) was growing at 2.8%. The country had a trade balance of −9.7% and unemployment rate of 14.7%. The Foreign direct investment has increased significantly in recent years as the government has embarked on an ambitious program to improve the business climate through fiscal and legislative reforms. The economy is expected to expand in the near term, driven by a recovery in consumption and robust investments. Growth is projected to be 3.2% in 2016, 3.5% in 2017, and 3.8% in 2018. === Primary sector === Agriculture in the country is based on small to medium-sized family-owned dispersed units. It remains a significant sector of the economy of Albania. It employs 41% of the population, and about 24.31% of the land is used for agricultural purposes. One of the earliest farming sites in Europe has been found in the southeast of the country. As part of the pre-accession process of Albania to the European Union, farmers are being aided through IPA funds to improve Albanian agriculture standards.Albania produces significant amounts of fruits (apples, olives, grapes, oranges, lemons, apricots, peaches, cherries, figs, sour cherries, plums, and strawberries), vegetables (potatoes, tomatoes, maize, onions, and wheat), sugar beets, tobacco, meat, honey, dairy products, traditional medicine and aromatic plants. Further, the country is a worldwide significant producer of salvia, rosemary and yellow gentian. The country's proximity to the Ionian Sea and the Adriatic Sea give the underdeveloped fishing industry great potential. The World Bank and European Community economists report that, Albania's fishing industry has good potential to generate export earnings because prices in the nearby Greek and Italian markets are many times higher than those in the Albanian market. The fish available off the coasts of the country are carp, trout, sea bream, mussels and crustaceans. Albania has one of Europe's longest histories of viticulture. The today's region was one of the few places where vine was naturally grown during the ice age. The oldest found seeds in the region are 4,000 to 6,000 years old. In 2009, the nation produced an estimated 17,500 tonnes of wine. During the communism, the production area expanded to some 20,000 hectares (49,000 acres). === Secondary sector === The secondary sector of Albania have undergone many changes and diversification, since the collapse of the communist regime in the country. It is very diversified, from electronics, manufacturing, textiles, to food, cement, mining, and energy. The Antea Cement plant in Fushë-Krujë is considered as one of the largest industrial greenfield investments in the country. Albanian oil and gas is represents of the most promising albeit strictly regulated sectors of its economy. Albania has the second largest oil deposits in the Balkan peninsula after Romania, and the largest oil reserves in Europe. The Albpetrol company is owned by the Albanian state and monitors the state petroleum agreements in the country. The textile industry has seen an extensive expansion by approaching companies from the European Union (EU) in Albania. According to the Institute of Statistics (INSTAT) as of 2016, the textile production marked an annual growth of 5.3% and an annual turnover of around 1.5 billion euros.Albania is a significant minerals producer and is ranked among the world's leading chromium producers and exporters. The nation is also a notable producer of copper, nickel and coal. The Batra mine, Bulqizë mine, and Thekna mine are among the most recognised Albanian mines that are still in operation. === Tertiary sector === The service industry represents the fastest growing sector of the Albanian economy. A significant part of Albania's national income derives from tourism. In 2016, it directly accounted for 8.4 percent of GDP, though including indirect contributions pushes the proportion to 26 percent. In the same year, Albania welcomed around 4.74 million visitors, mostly from Southern Europe and several countries from the European Union and also the United States. The increase of foreign visitors has been dramatic. Albania had only 500,000 visitors in 2005, while in 2012 had an estimated 4.2 million, an increase of 740 percent in only 7 years. In 2015, tourism in summer increased by 25 percent in contrast the previous year, accouring to the country's tourism agency. In 2011, Lonely Planet named as a top travel destination, while The New York Times placed Albania as number 4 global touristic destination in 2014.The bulk of the tourist industry is concentrated along the Adriatic and Ionian Sea in the west of the country. However, the Albanian Riviera in the southwest has the most scenic and pristine beaches, and is often called the pearl of the Albanian coast. Its coastline has a considerable length of 446 kilometres (277 miles). The coast has a particular character because it is rich in varieties of virgin beaches, capes, coves, covered bays, lagoons, small gravel beaches, sea caves and many landforms. Some parts of this seaside are very clean ecologically, which represent in this prospective unexplored areas, which are very rare within the Mediterranean. Other attractions include the mountainous areas such as the Albanian Alps, Ceraunian Mountains and Korab Mountains but also the historical cities of Berat, Durrës, Gjirokastër, Sarandë, Shkodër and Korçë. == Infrastructure == Following the end of communism in Albania, the transportation has undergone significant changes in the past two decades, vastly modernizing the country's infrastructure. Improvements to the road infrastructure, urban transport, and air travel have all led to a vast improvement in transportation. Currently there are three main motorways in Albania including the A1, A2 and the A3. The A1 motorway represents a major west–east transportation corridor in Albania, connecting the country's second largest city Durrës to Pristina, the capital of Kosovo. Prospectively, the motorway will link with Pan-European Corridor X near Niš in Serbia. The project was the largest and most expensive infrastructure road project undertaken in the country. Two additional highways are currently under construction. The A3 motorway is going to connect the country's capital city Tirana with the Pan-European Corridor VIII, connecting Albania with Macedonia and Bulgaria to the east. The north-south corridor consists of SH1 and SH2 and makes up the Albanian portion of the Adriatic–Ionian motorway, a larger regional highway connecting Croatia in the north with Greece in the south, along the Adriatic and Ionian Sea. When all three corridors are completed, Albania will have an estimated 759 kilometres (472 mi) of highway linking it with all of its neighboring countries. The busiest and largest seaport in the country is the Port of Durrës. As of 2014, the port ranks as one of the largest passenger ports on the Adriatic Sea, with annual passenger volume of approximately 1.5 million. Other seaports include Vlorë, Sarandë and Shëngjin. The ports serve an extensive system of ferries connecting numerous islands and coastal cities in addition to ferry lines to several cities in Croatia, Greece and Italy. The only international airport in the country is the Tirana International Airport. It is the only port of entry for air travelers into the country. In 2016, the Government of Albania reached an agreement with the airport to end its monopoly on flights, paving the way for the opening of an airport near Kukës in the north.The railways in the country are administered by the national railway company Hekurudha Shqiptare. The railway system was extensively promoted by the totalitarian communist regime of dictator Enver Hoxha, during which time the use of private transport was effectively prohibited. Since the end of communism, there has been a considerable increase in car ownership and bus usage. A new railway line from Tirana via Tirana International Airport to Durrës is currently planned. The location of this railway, connecting the most populated urban areas in Albania, makes it an important economic development project. The opening will take place in 2019. === Energy === Albania is mostly dependent on hydroelectricity. Almost 94.8% of the country's electricity consumption comes from hydroelectrical stations and ranks 7th in the world by percentage. There are six hydroelectric power stations, including Fierza, Koman, Skavica and Vau i Dejës situated within the Drin River. Further, there are two stations under construction, namely Banjë and Moglicë located in the Devoll River. Both are expected to be completed between 2016 and 2018. Albania has considerably large deposits of oil. It has the 10th largest oil reserves in europe and the 58th in the world. The country's main petroleum deposits are located around the Albanian Adriatic Sea Coast and Myzeqe Plain within the Western Lowlands, where the country's largest reserve is located. Although, Patos-Marinza, also located within the area, is the largest onshore oil field in europe.In 2015, 498 kilometres (309 mi) of natural gas pipelines and 249 kilometres (155 mi) of oil pipelines spanned the country's territory. The planned Trans Adriatic Pipeline, a major trans Adriatic Sea gas pipeline, will delivers natural gas from Azerbaijan to Albania and Western Europe through Italy and will be completed in 2020.Further, Albania and Croatia have discussed the possibility of jointly building a nuclear power plant at Lake Shkodër, close to the border with Montenegro, a plan that has gathered criticism from Montenegro due to seismicity in the area. In 2009, the company Enel announced plans to build an 800 MW coal-fired power plant in the country, to diversify electricity sources. === Science, technology and media === With the political and economic changings in 1993, human resources in sciences and technology have drastically decreased. As of various reports, during 1991 to 2005 approximately 50% of the professors and scientists of the universities and science institutions in the country have left Albania. In 2009, the government approved the National Strategy for Science, Technology and Innovation in Albania covering the period 2009 to 2015. It aims to triple public spending on research and development to 0.6% of GDP and augment the share of GDE from foreign sources, including the framework programmes for research of the European Union, to the point where it covers 40% of research spending, among others. During the communism, the country was one of the world's most isolated and controlled countries, while installation and maintenance of a modern system of international and national telecommunications was precluded. Callers previously needed operator assistance even to make domestic long-distance calls. Nowadays, providers such as Vodafone, Telekom, Albanian Mobile, Plus and Eagle Mobile provide both 3G and 4G data plans. Although, Internet is fast and inexpensive in comparison to the rest of Western Europe. In 2016, there were 1.82 million Internet users in the country, in percentage 63% of the population. Albania has an estimated 257 media outlets, including 66 radio stations and 67 television stations, with 65 national and more than 50 cable television stations. Radio began officially in 1938 with the founding of Radio Televizioni Shqiptar, while television broadcasting began in 1960. 4 regional radio stations serve in the four extremities of the country. The international service broadcasts radio programmes in Albanian including seven other languages through medium wave and short wave, using the theme from the song "Keputa një gjethe dafine" as its signature tune. The international television service through satellite was launched since 1993 and aims at Albanian communities in the neighboring countries and the Albanian diaspora. Nowadays, the country has organized several shows as a part of worldwide series like Dancing with the Stars, Big Brother, Got Talent, The Voice and X Factor. === Education === Following the end of communism in 1991, a reorganization plan was announced that would extend the compulsory education program from eight to ten years. The following year, major economic and political crisis in Albania, and the ensuing breakdown of public order, plunged the school system into chaos. Widespread vandalism and extreme shortages of textbooks and supplies had a devastating effect on school operations, prompting Italy and other countries to provide material assistance. In the late 1990, many schools were rebuilt or reconstructed, to improve learning conditions. Most of the improvements have happened in the larger cities of the country especially in Tirana, Durrës and Shkodër. All educational programmes in Albania are regulated by the Ministry of Education and administered by local municipalities. Education is mostly supported by the state and is composed of three stages, primary education (arsimi fillorë), secondary education (arsimi i mesëm), and tertiary education (arsimi universitarë). The academic year is very similar to the one in the United States, with classes starting in September or October and ending in June or July. Albanian is the primary language of instruction in all public schools. The primary education is obligatory from grade one to nine. Students must pass the graduation exams at the end of the 9th grade in order to continue their education. After the primary school, the general education is provided at the secondary schools. Students get prepared for the Matura examination, allowing them to obtain their matura diploma, which grants admission to higher education. Although, Albania follows the Bologna model in accordance with the 2007 Law on Higher Education. These institutions can be public or private, and may offer one, two or three levels of higher education depending on the institution.The school life expectancy of Albania is 16 years, ranking 25th in the world. Literacy rate in Albania is 99.2% for males and 98.3% for females, having an overall of 98.7%. === Health === Albania has a universal health care system run by the Ministry of Health. According to the World Health Organization, Albania had the world's 55th best healthcare performance in 2000. The system has been in a steep decline since the collapse of communism in the country, but a process of modernization has been taking place since 2000. There were a total of 51 hospitals in 2000 in the country, including a military hospital and specialist facilities. The most common causes of death are circulatory diseases followed by cancerous illnesses. Demographic and Health Surveys completed a survey in April 2009, detailing various health statistics in Albania, including male circumcision, abortion and more. The leading causes of death are cardiovascular disease, trauma, cancer, and respiratory disease. Albania has successfully eradicated diseases such as malaria. Life expectancy is estimated at 77.8 years, ranking thirty-seventh in the world and outperforming numerous countries within the European Union such as Slovenia, Estonia, Poland, Hungary and Slovakia. The average healthy life expectancy in Albania in 2015 is 68.8 years and ranks as well thirty-seventh in the world. The country's infant mortality rate is estimated at 12 per 1,000 live births in 2015. Compared to other European countries, Albania has a relatively low rate of obesity, probably thanks to the health benefits of the Mediterranean diet. == Demographics == The population of Albania, as defined by Institute of Statistics, was estimated in 2016 to be approximately 2,886,026. The country's total fertility rate of 1.51 children born per woman is one of the lowest in the world. Its population density stands at 259 inhabitants per square kilometre. The overall life expectancy at birth is 78.5 years; 75.8 years for males and 81.4 years for females. The country is the 8th most populous country in the Balkans and ranks as the 137th most populous country in the world. The population of the country rose steadily from 2,5 million in 1979 until 1989, when it peaked at 3.1 million. It is forecasted that the population should not reach its peak number of 1989 until 2031, depending on the actual birth rate and the level of net migration.The explanation for the recent population decrease is the fall of communism in Albania. It was marked by large economic mass emigration from Albania to Greece, Italy and the United States. 40 years of isolation from the world, combined with its disastrous economic, social and political situation, had caused this exodus. The external migration was prohibited outright during the communism, while internal migration was quite limited, hence this was a new phenomenon. At least, 900,000 people left Albania during this period, about 600,000 of them settling in Greece. The migration affected the country's internal population distribution. It decreased particularly in the north and south, while it increased in the center within the cities of Tirana and Durrës. According to the Institute of Statistics (INSTAT) as of 1 January 2015, the population of Albania is 2,893,005.About 53.4% of the country's population is living in cities. The three largest counties by population account for half of the total population. Almost 30% of the total population is found in Tirana County followed by Fier County with 11% and Durrës County with 10%. Over 1 million people are concentrated in Tirana and Durrës, making it the largest urban area in Albania. Tirana is one of largest cities in the Balkan Peninsula and ranks 7th with a population about 800,000. The second largest city in the country by population is Durrës, with a population of 201.110, followed by Vlorë with a population of 141.513. === Minorities === Issues of ethnicity are a delicate topic and subject to debate. Contrary to official statistics that show an over 97 per cent Albanian majority in the country, minority groups (such as Greeks, Macedonians, Montenegrins, Roma and Aromanians) have frequently disputed the official numbers, asserting a higher percentage of the country's population. According to the disputed 2011 census, ethnic affiliation was as follows: Albanians 2,312,356 (82.6% of the total), Greeks 24,243 (0.9%), Macedonians 5,512 (0.2%), Montenegrins 366 (0.01%), Aromanians 8,266 (0.30%), Romani 8,301 (0.3%), Balkan Egyptians 3,368 (0.1%), other ethnicities 2,644 (0.1%), no declared ethnicity 390,938 (14.0%), and not relevant 44,144 (1.6%). On the quality of the specific data the Advisory Committee on the Framework Convention for the Protection of National Minorities stated that "the results of the census should be viewed with the utmost caution and calls on the authorities not to rely exclusively on the data on nationality collected during the census in determining its policy on the protection of national minorities.".Albania recognizes nine national or cultural minorities: Greek, Macedonian, Wallachian, Montenegrin, Serb, Roma, Egyptian, Bosnian and Bulgarian peoples. Other Albanian minorities are Gorani, Aromanians and Jews. Regarding the Greeks, "it is difficult to know how many Greeks there are in Albania". The estimates vary between 60,000 and 300,000 ethnic Greeks in Albania. According to Ian Jeffries, most of Western sources put the number at around 200,000. The 300,000 mark is supported by Greek government as well. The CIA World Factbook estimates the Greek minority at 0.9% of the total population. The US State Department uses 1.17% for Greeks and 0.23% for other minorities. The latter questions the validity of the census data about the Greek minority, due to the fact that measurements have been affected by boycott.Macedonian and some Greek minority groups have sharply criticized Article 20 of the Census law, according to which a $1,000 fine will be imposed on anyone who will declare an ethnicity other than what is stated on his or her birth certificate. This is claimed to be an attempt to intimidate minorities into declaring Albanian ethnicity, according to them the Albanian government has stated that it will jail anyone who does not participate in the census or refuse to declare his or her ethnicity. Genc Pollo, the minister in charge has declared that: "Albanian citizens will be able to freely express their ethnic and religious affiliation and mother tongue. However, they are not forced to answer these sensitive questions". The amendments criticized do not include jailing or forced declaration of ethnicity or religion; only a fine is envisioned which can be overthrown by court.Greek representatives form part of the Albanian parliament and the government has invited Albanian Greeks to register, as the only way to improve their status. On the other hand, nationalists, various organizations and political parties in Albania have expressed their concern that the census might artificially increase the numbers of the Greek minority, which might be then exploited by Greece to threaten Albania's territorial integrity. === Language === Albanian is the official language of the Republic of Albania. Its standard spoken and written form is revised and merged from the two main dialects, Gheg and Tosk, though it is notably based more on the Tosk dialect. The Shkumbin river is the rough dividing line between the two dialects. Also a dialect of Greek that preserves features now lost in standard modern Greek is spoken in areas inhabited by the Greek minority. Other languages spoken by ethnic minorities in Albania include Aromanian, Serbian, Macedonian, Bosnian, Bulgarian, Gorani, and Roma. Macedonian is official in the Pustec Municipality in East Albania. According to the 2011 population census, 2,765,610 or 98.767% of the population declared Albanian as their mother tongue (mother tongue is defined as the first or main language spoken at home during childhood). Greek is the second most-spoken language in the country, with 0.5 to 3% of the population speaking it as first language, and with two-thirds of mainly Albanian families having at least one member that speaks Greek, most having learned it in the post communist era (1992-present) due to private schools or migration to Greece. Outside of the small designated "minority area" in the south the teaching of Greek was banned during the communist era. As of 2003 Greek is offered at over 100 private tutoring centers all over Albania and at a private school in Tirana, the first of its kind outside Greece. In recent years, the shrinking number of pupils in schools dedicated to the Greek minority has caused problems for teachers. The Greek language is spoken by an important percentage in the southern part of the country, due to cultural and economic links with adjacent Greece. In a 2017 study carried out by Instat, the Albanian government statistical agency, 39.9 % of the 25-64 years old is able to use at least one foreign language, with English first at 40.0%, followed by Italian with 27.8% and Greek with 22.9 %. Among young people aged 25 or less, English, German and Turkish have seen a rising interest after 2000. Italian and French have had a stable interest, while Greek has lost most of the interest. The trends are linked with cultural and economic factors.The young people have shown a growing interest in German language in recent years. Some of them go to Germany for studying or various experiences. Albania and Germany have agreements for cooperating in helping young people of the two countries know both cultures better. Due to a sharp rise in economic relations with Turkey, interest in learning Turkish, in particular among young people, has been growing on a yearly basis. Young people, attracted by economic importance of Turkish investments and common values between the two nations, gain from cultural and academic collaboration of universities. In 2011 Turkish-owned Epoka University, where Turkish along with English and French is taught, was chosen the best foreign-owned university in Albania. === Religion === Albania is a secular state without an official religion, with the freedom of religion being a constitutional right. The 2011 census, for the first time since 1930, included an optional open-ended question on religion; the census recorded a majority of Muslims (58.79%), which include Sunni (56.70%) and Bektashi Muslims (2.09%). Christians, making up 16.92% of the population, include Roman Catholics (10.03%), Orthodox (6.75%) and evangelical Protestants (0.14%).Atheists accounted for 2.5% of the population and 5.49% were non-affiliated believers, while 13.79% preferred not to answer.The preliminary results of the 2011 census seemed to give widely different results, with 70% of respondents refusing to declare belief in any of the listed faiths. The Albanian Orthodox Church officially refused to recognize the results, claiming that 24% of the total population adhered to its faith. Some Muslim Community officials expressed unhappiness with the data claiming that many Muslims were not counted and that the number of adherents numbered some 70% of the Albanian population. The Albanian Catholic Bishops Conference also cast doubts on the census, complaining that many of its believers were not contacted. The Muslim Albanians are spread throughout the country. Orthodox and Bektashis are mostly found in the south, whereas Catholics mainly live in the north. In 2008, there were 694 Catholic churches and 425 orthodox churches, 568 mosques and 70 bektashi tekkes in the country. Religious tolerance is one of the most important values of the tradition of the Albanians. It is widely accepted that Albanians generally value a peaceful coexistence among the believers of different religious communities in the country. During an official visit in Tirana, Pope Francis hailed Albania as model of religious harmony, due to the long tradition of religious coexistence and tolerance. The country is ranked among the least religious countries in the world. Furthermore, religion plays an important role in the lives of only 39% of the country's population. In the WIN/Gallup International Report of 2016, 56% of the Albanian people considered themselves religious, 30% considered themselves non-religious, while 9% defined themselves as convinced atheists; 80% believed in God and 40% believed in life after death. However, 40% believed in hell, while 42% believed in heaven.During classical times, there are thought to have been about seventy Christian families in Durrës, as early as the time of the Apostles. The Archbishopric of Durrës was purportedly founded by Paul the Apostle, while preaching in Illyria and Epirus. Meanwhile, in medieval times, the Albanian people first appeared within historical records from the Byzantines. At this point, they were mostly Christianized. Islam arrived for the first time in the late 9th century to the region, when Arabs raided parts of the eastern banks of the Adriatic Sea. It later emerged as the majority religion, during the centuries of Ottoman Period, though a significant Christian minority remained. During modern times, the Albanian republican, monarchic and later communist regimes followed a systematic policy of separating religion from official functions and cultural life. The country has never had an official religion either as a republic or as a kingdom. In the 20th century, the clergy of all faiths was weakened under the monarchy and ultimately eradicated during the 1950s and 1960s, under the state policy of obliterating all organized religion from the territories of Albania. The communist regime persecuted and suppressed religious observance and institutions and entirely banned religion. The country was then officially declared to be the world's first atheist state. Although, the country's religious freedom has returned, since the end of communism. Islam survived communist era persecution and reemerged in the modern era as a practiced religion in Albania. Some smaller Christian sects in Albania include Evangelicals and several Protestant communities including Seventh-day Adventist Church, Church of Jesus Christ of Latter-day Saints and Jehovah's Witnesses. The first recorded Protestant of Albania was Said Toptani, who traveled around Europe and returned to Tirana in 1853, where he preached Protestantism. Due to that, he was arrested and imprisoned by the Ottoman authorities in 1864. First evangelical Protestants appeared in the 19th century and the Evangelical Alliance was founded in 1892. Nowadays, it has 160 member congregations from different Protestant denominations. Albania was the only country in Europe where the Jewish population increased significantly during the Holocaust. Following the mass emigration to Israel, since the fall of communism, only 200 Albanian Jews are left in the country. == Culture == === Symbols === Albania shares many symbols associated with its history, culture and belief. These include the colours red and black, animals such as the golden eagle living across the country, costumes such as the fustanella, plis and opinga which are worn to special events and celebrations, plants such as the olive and red poppy growing as well across the country. The flag of Albania is a red flag with a black double-headed eagle in the centre. The red colour symbolizes the bravery, strength and valour of the Albanian people and the black colour appears as a symbol of freedom and heroism. Moreover, the eagle has been used by Albanians since the Middle Ages including the establishment of the Principality of Arbër and by numerous noble ruling families such as the Kastrioti, Muzaka, Thopia and Dukagjini. Gjergj Kastrioti Skënderbeu, who fought and began a rebellion against the Ottoman Empire which halted Ottoman advance into Europe for nearly 25 years, placed the double-headed eagle on his flag and seal. The country's national motto, Ti Shqipëri, më jep nder, më jep emrin Shqipëtar, finds its origins in the early 19th century. The first to express this motto was Naim Frashëri in his poem Ti Shqipëri më jep nder. This poem is notable as refers to the values and ambitions of the Albanian people to remain separate from and independent of, those neighbouring countries around it, which have tried to dominate it. The duart e kryqëzuara, also referred to as the eagle gesture, is a gesture performed particularly by the Albanian people around the world in order to visually illustrate the double-headed eagle, the symbol of Albania. === Cuisine === Albanian cuisine has evolved over the centuries and has been strongly influenced by the geography and history of Albania. Previously home to the Illyrians and Ancient Greeks and then subsequently conquered and occupied by the Byzantines, Ottomans and most recently the Italians, it has borrowed elements and styles from those cultures. The cooking traditions vary especially between the north and the south, due to differing topography and climate, that provides excellent growth conditions for various herbs, vegetables and fruits. One of the most characteristic element is olive oil, which is the major type of oil used for cooking produced from olive trees prominent throughout the south of the country. Albanians uses a wide range of ingredients, including a wider availability of vegetables such as beans, tomatoes, peppers, potatoes, onions and garlics, as well as cereals such as wheat, corn and rye. Herbs and spices include oregano, mint, lavender and basil. Widely used meat varieties are lamb, beef, veal, chicken and other poultry and pork. Seafood specialities are particularly popular along the Albanian Adriatic and Ionian Sea Coasts in the west. Tavë Kosi is a national dish and is prepared with baked lamb as well as eggs and yogurt, while garlic, oregano and other herbs can be added as well. Petulla, a traditionally fried dough made from wheat or buckwheat flour, is as well a popular speciality and is served with powdered sugar or feta cheese and fruit jams. Another dish, called Fërgese, is a vegetarian dish made of green and red peppers along with skinned tomatoes and onions; it often served as a side dish to meat dishes. Also, popular is Flia, consisting of multiple crepe-like layers brushed with cream and served with sour cream. Krofne, similar to Berliner Pfannkuchen, are filled with jam, marmalade chocolate and often eaten during the cold winter months. Desserts include Walnut Stuffed Figs that is made of walnuts or candied walnuts and fig syrup. Although fig is an important agricultural product of Albania. Bakllavë is also a widely consumed dessert and traditionally eaten during Christmas, Easter and Ramadan. Tea is enjoyed both at home or outside at cafés, bars or restaurants. Çaj Mali is enormously beloved and is part of a daily routine for most of the Albanians. It is cultivated around the south of Albania and noted for its medicinal properties. Black tea with a slice of lemon and sugar, milk or honey is also a popular type of tea. Withal, coffee is by far one of the most consumed beverages in Albania, with several types of filter and instant coffee. Drinking coffee is very much a part of the people's lifestyle. Wine drinking is popular throughout the Albanians. The country has a long and ancient history of wine production, as it belongs to the old world of wine producing countries. Its wine is characterized for its sweet taste and traditionally indigenous varieties. === Architecture === The architecture of Albania reflects the legacy of various civilizations tracing back to the classical antiquity. Major cities in Albania have evolved from within the castle to include dwellings, religious and commercial structures, with constant redesigning of town squares and evolution of building techniques. Nowadays, the cities and towns reflect a whole spectrum of various architectural styles. In the 20th century, many historical as well as sacred buildings bearing the ancient influence were demolished during the communism.Outstanding ancient architecture is found throughout Albania and most visible in Byllis, Amantia, Phoenice, Apollonia, Butrint, Antigonia, Shkodër and Durrës. Considering the long period of rule of the Byzantine Empire, they introduced castles, citadels, churches and monasteries with spectacular wealth of visible murals and frescos. Perhaps the best known examples can be found in the southern Albanian cities and surroundigs of Korçë, Berat, Voskopojë and Gjirokastër. Involving the introduction of Ottoman architecture there was a development of mosques and other Islamic buildings, particularly seen in Berat and Gjirokastër. A productive period of Historicism, Art Nouveau and Neoclassicism merged into the 19th century, best exemplified in Korçë. The 20th century brought new architectural styles such as the modern Italian style, which is present in Tirana such as the Skanderbeg Square and Ministries. It is also present in Shkodër, Vlorë, Sarandë and Durrës. Moreover, other towns received their present-day Albania-unique appearance through various cultural or economic influences. Socialist classicism arrived during the communism in Albania after the Second World War. At this period many socialist-styled complexes, wide roads and factories were constructed, while town squares were redesigned and numerous of historic and important buildings demolished. Notable examples of that style include the Mother Teresa Square, Pyramid of Tirana, Palace of Congresses and so on. Two Albanian archaeological sites are included in the list of UNESCO World Heritage Sites. These include the ancient remains of Butrint and the medieval Historic Centres of Berat and Gjirokastër. Furthermore, the natural and cultural heritage of Ohrid, the royal Illyrian tombs, the remains of Apollonia, the ancient Amphitheatre of Durrës and the Fortress of Bashtovë has been included on the tentative list of Albania. === Music === The Albanian folk music is a prominent section of the national identity and continues to play a major part in Albanian music. Although, it can be divided into two stylistic groups, as performed by the northern Ghegs and southern Labs and Tosks. The northern and southern traditions are contrasted by the rugged tone of the north and the relaxed form of the south. Many of the songs are about events from history and culture, including the traditional themes about honour, hospitality, treachery and revenge. The first compilation of Albanian folk music was made by two Himariot musicians Neço Muka and Koço Çakali in Paris, during their interpretations with the song Diva Tefta Tashko Koço. Several gramophone compilations were recorded in those years by this genial trio of artists which eventually led to the recognition of the Himariot Isopolyphonic Music as an UNESCO World Cultural Heritage. The contemporary music artists Rita Ora, Bebe Rexha, Era Istrefi, Dua Lipa, Bleona, Elvana Gjata, Ermonela Jaho and Inva Mula have achieved international recognition for their music. Sporano Ermonela Jaho has been described by The Economist as the World's most acclaimed Soprano. One widely recognized musician from Elbasan is Saimir Pirgu, an Albanian international opera singer. He was nominated for the 2017 Grammy Award.Every cultural and geographical region of Albania has its own specific variety of costume that vary in style, material, color, shape, detail and form. Presently, the national costumes are most often worn with connection to special events and celebrations, mostly at ethnic festivals, religious holidays, weddings and by dancing groups as well. Some conservative old men and women mainly from the high northern as well as southern regions and wear traditional clothing in their daily lives. The clothing was made mainly of products from the local agriculture and livestock such as leather, wool, linen, hemp fiber and silk. Nowadays, the traditional textiles are still embroidered in very collaborate ancient patterns. === Arts === The visual arts tradition of Albania has been shaped by the many cultures, which have flourished on its territory. Once the Byzantines, the Ottomans ruled over Albania for nearly five centuries, which greatly affected the country's artwork and artistic forms. After Albania's joining with the Ottoman Empire in 1478, Ottoman influenced art forms such as mosaic and mural paintings became prevalent and no real artistic change occurred until the independence in 1912. Following mosaics and murals from Antiquity and the Middle Ages, the first paintings were icons Byzantine traditions. Albanian earliest icons date from the late 13th century and generally estimated that their artistic peak reached in the 18th century. Among the most prominent representatives of the Albanian iconographic art were Onufri and David Selenica. The museums of Berat, Korçë and Tirana houses good collections remaining icons. By the end of the Ottoman rule, the painting was limited mostly to folk art and ornate mosques. Paintings and sculpture arose in the first half of the twentieth century and reached a modest peak in the 1930s and 1940s, when the first organized art exhibitions at national level. Contemporary Albanian artwork captures the struggle of everyday Albanians, however new artists are utilizing different artistic styles to convey this message. Albanian artists continue to move art forward, while their art still remains distinctively Albanian in content. Though among Albanian artist post-modernism was fairly recently introduced, there is a number of artists and works known internationally. Among the most prominent Albanian post-modernist are considered Anri Sala, Sislej Xhafa, and Helidon Gjergji. === Literature === The Albanian language comprises its own branch of the Indo-European language family. The language is considered an isolate within the Indo-European. The only other languages that are the sole surviving member of a branch of Indo-European are Armenian and Greek. It was proved to be an Indo-European language in 1854 by the German philologist Franz Bopp. Albanian is often held to be related to the Illyrian languages, a language spoken in the Balkans during classical times. Scholars argue that Albanian derives from Illyrian while some others claim that it derives from Daco-Thracian. (Illyrian and Daco-Thracian, however, might have been closely related languages; see Thraco-Illyrian.) The cultural renaissance was first of all expressed through the development of the Albanian language in the area of church texts and publications, mainly of the Catholic region in the northern of Albania, but also of the Orthodox in the south. The Protestant reforms invigorated hopes for the development of the local language and literary tradition, when cleric Gjon Buzuku brought into the Albanian language the Catholic liturgy, trying to do for the Albanian language, what Martin Luther did for the German language. Meshari (The Missal) written by Gjon Buzuku was published in 1555 and is considered as one of the first literary work of written Albanian during the Middle Ages. The refined level of the language and the stabilised orthography must be the result of an earlier tradition of written Albanian, a tradition that is not well understood. However, there is some fragmented evidence, pre-dating Buzuku, which indicates that Albanian was written from at least the 14th century. The earliest evidence dates from 1332 AD with a Latin report from the French Dominican Guillelmus Adae, Archbishop of Antivari, who wrote that Albanians used Latin letters in their books although their language was quite different from Latin. Other significant examples include: a baptism formula (Unte paghesont premenit Atit et Birit et spertit senit) from 1462, written in Albanian within a Latin text by the Bishop of Durrës, Pal Engjëlli; a glossary of Albanian words of 1497 by Arnold von Harff, a German who had travelled through Albania, and a 15th-century fragment of the Bible from the Gospel of Matthew, also in Albanian, but written in Greek letters. Albanian writings from these centuries must not have been religious texts only, but historical chronicles too. They are mentioned by the humanist Marin Barleti, who in his book Siege of Shkodër (Rrethimi i Shkodrës) from 1504, confirms that he leafed through such chronicles written in the language of the people (in vernacula lingua) as well as his famous biography of Skanderbeg Historia de vita et gestis Scanderbegi Epirotarum principis (History of Skanderbeg) from 1508. The History of Skanderbeg is still the foundation of Skanderbeg studies and is considered an Albanian cultural treasure, vital to the formation of Albanian national self-consciousness. During the 16th and the 17th centuries, the catechism (E mbësuame krishterë) (Christian Teachings) from 1592 written by Lekë Matrënga, (Doktrina e krishterë) (The Christian Doctrine) from 1618 and (Rituale romanum) 1621 by Pjetër Budi, the first writer of original Albanian prose and poetry, an apology for George Castriot (1636) by Frang Bardhi, who also published a dictionary and folklore creations, the theological-philosophical treaty Cuneus Prophetarum (The Band of Prophets) (1685) by Pjetër Bogdani, the most universal personality of Albanian Middle Ages, were published in Albanian. The most famous Albanian writer in the 20th and 21st century is probably Ismail Kadare. He has been mentioned as a possible recipient of the Nobel Prize in Literature several times. === Cinema === Cinematography became popular in the 20th century, when foreign films and documentaries were shown in the cities of Shkodër and Korçë. The first public showing to occur in Albania was a little-known title, Paddy the Reliable a comical story. The first Albanian films were mostly documentaries; the first was about the Monastir Congress that sanctioned the Albanian alphabet in 1908. During communism, the Albanian Film Institute that later became known as Kinostudio Shqipëria e Re was founded with Soviet assistance, focusing mostly on propaganda of wartime struggles. After 1945, the communist government founded the Kinostudio Shqipëria e Re in 1952. This was followed by the first Albanian epic film, the Great Warrior Skanderbeg, a cooperation with Soviet artists chronicling the life and fight of the Albanian national hero Skanderbeg. In addition the film was awarded the International Prize at the 1954 Cannes Film Festival. By 1990, about 200 movies had been produced, and Albania had over 450 theaters. With the economic transition after the collapse of communism in the 1990s, the Kinostudio was broken up and privatised. A new National Center of Cinematography was established, while cities built modern cinema theatres showing mostly American movies. The Tirana International Film Festival was established in 2003 and has become the premier and largest film festival in the country as well as in the Balkans. Durrës hosts the International Film Summerfest of Durrës, the second largest international film festival in the country which takes place every year in late August or early September in Durrës Amphitheatre. Notable Albanian film directors include Andamion Murataj, Besim Sahatçiu, Xhanfize Keko, Dhimitër Anagnosti, Kujtim Çashku, Luljeta Hoxha, Saim Kokona, Saimir Kumbaro, Kristaq Mitro, Leon Qafzezi and Gjergj Xhuvani. Famous actors in Albania include Nik Xhelilaj, Klement Tinaj, Masiela Lusha, Blerim Destani, Aleksandër Moisiu, Tinka Kurti, Pjetër Malota, Sandër Prosi and Margarita Xhepa. There are internationally renowned actors in the Albanian diaspora, such as the Albanian-Americans Eliza Dushku, Jim and John Belushi, Kosovo-Albanians Bekim Fehmiu and Arta Dobroshi and Turkish-Albanian Barish Arduç. === Sports === Albania participated at the Olympic Games in 1972 for the first time. The country made their Winter Olympic Games debut in 2006. Albania missed the next four games, two of them due to the 1980 and 1984 boycotts, but returned for the 1992 games in Barcelona. Since then, Albania have participated in all games. Albania normally competes in events that include swimming, athletics, weightlifting, shooting and wrestling. The country have been represented by the National Olympic Committee of Albania since 1972. The nation has participated at the Mediterranean Games since the games of 1987 in Syria. The Albanian athletes have won a total of 43 (8 gold, 17 silver and 18 bronze) medals from 1987 to 2013. Popular sports in Albania include Football, Weightlifting, Basketball, Volleyball, Tennis, Swimming, Rugby, and Gymnastics. Football is by far the most popular sport in Albania. It is governed by the Football Association of Albania (Albanian: Federata Shqiptare e Futbollit, F.SH.F.), which was created in 1930 and has membership in FIFA and UEFA. Football arrived in Albania early in the 20th century when the inhabitants of the northern city of Shkodër were surprised to see a strange game being played by students at a Christian mission. The Albania national football team, ranking 51st in the World in 2017 (highest 22nd on August 22, 2015) have won the 1946 Balkan Cup and the Malta Rothmans International Tournament 2000, but had never participated in any major UEFA or FIFA tournament, until UEFA Euro 2016, Albania's first ever appearance at the continental tournament and at a major men's football tournament. Albania scored their first ever goal in a major tournament and secured their first ever win in European Championship when they beat Romania by 1–0 in a UEFA Euro 2016 match on 19 June 2016. The most successful football clubs in the country are Skënderbeu, KF Tirana, Dinamo Tirana, Partizani and Vllaznia. Weightlifting is one of the most successful individual sport for the Albanians, with the national team winning medals at the European Weightlifting Championships and the rest international competitions. Albanian weightlifters have won a total of 16 medals at the European Championships with 1 of them being gold, 7 silver and 8 bronze. In the World Weightlifting Championships, the Albanian weightlifting team has won in 1972 a gold in 2002 a silver and in 2011 a bronze medal. === Diaspora === Historically, the Albanian people have established several communities in many regions throughout Southern Europe. The Albanian diaspora has been largely formed during the early Middle Ages, when they emigrated to Italy, especially in Sicily and Calabria, but as well as to Greece to escape either various socio-political difficulties and the Ottoman conquest of Albania. Following the fall of communism, large numbers of Albanians have migrated to countries such as Australia, Canada, France, Germany, Greece, Italy, Scandinavia, Switzerland, United Kingdom and the United States. Albanian minorities are present in the neighboring countries of Macedonia, Montenegro and Serbia. In Kosovo, Albanians makes up the largest ethnic group in the country. Altogether, the number of ethnic Albanian living abroad its territory is estimated to be higher than the total population inside the territory of Albania. == See also == Outline of Albania Index of Albania-related articles Bibliography of Albania List of Albanians Albania – Wikipedia book == Notes == == References == == Further reading == History of the Party of Labor of Albania.

### Instruction: retrieve labels for this: Allah (; Arabic: الله‎, translit. Allāh, IPA: [ɑɫˈɫɑː(h)] ( listen)) is the Arabic word for God in Abrahamic religions. In the English language, the word generally refers to God in Islam. The word is thought to be derived by contraction from al-ilāh, which means "the god", and is related to El and Elah, the Hebrew and Aramaic words for God.The word Allah has been used by Arabic people of different religions since pre-Islamic times. More specifically, it has been used as a term for God by Muslims (both Arab and non-Arab) and Arab Christians. It is also often, albeit not exclusively, used in this way by Bábists, Bahá'ís, Mandaeans, Indonesian and Maltese Christians, and Mizrahi Jews. Similar usage by Christians and Sikhs in West Malaysia has recently led to political and legal controversies, such as There is no god but Allah. == Etymology == The etymology of the word Allāh has been discussed extensively by classical Arab philologists. Grammarians of the Basra school regarded it as either formed "spontaneously" (murtajal) or as the definite form of lāh (from the verbal root lyh with the meaning of "lofty" or "hidden"). Others held that it was borrowed from Syriac or Hebrew, but most considered it to be derived from a contraction of the Arabic definite article al- "the" and ilāh "deity, god" to al-lāh meaning "the deity", or "the God". The majority of modern scholars subscribe to the latter theory, and view the loanword hypothesis with skepticism.Cognates of the name "Allāh" exist in other Semitic languages, including Hebrew and Aramaic. The corresponding Aramaic form is Elah (אלה), but its emphatic state is Elaha (אלהא). It is written as ܐܠܗܐ (ʼĔlāhā) in Biblical Aramaic and ܐܲܠܵܗܵܐ (ʼAlâhâ) in Syriac as used by the Assyrian Church, both meaning simply "God". Biblical Hebrew mostly uses the plural (but functional singular) form Elohim (אלהים‬), but more rarely it also uses the singular form Eloah (אלוהּ‬). == Usage == === Pre-Islamic Arabians === Regional variants of the word Allah occur in both pagan and Christian pre-Islamic inscriptions. Different theories have been proposed regarding the role of Allah in pre-Islamic polytheistic cults. Some authors have suggested that polytheistic Arabs used the name as a reference to a creator god or a supreme deity of their pantheon. The term may have been vague in the Meccan religion. According to one hypothesis, which goes back to Julius Wellhausen, Allah (the supreme deity of the tribal federation around Quraysh) was a designation that consecrated the superiority of Hubal (the supreme deity of Quraysh) over the other gods. However, there is also evidence that Allah and Hubal were two distinct deities. According to that hypothesis, the Kaaba was first consecrated to a supreme deity named Allah and then hosted the pantheon of Quraysh after their conquest of Mecca, about a century before the time of Muhammad. Some inscriptions seem to indicate the use of Allah as a name of a polytheist deity centuries earlier, but we know nothing precise about this use. Some scholars have suggested that Allah may have represented a remote creator god who was gradually eclipsed by more particularized local deities. There is disagreement on whether Allah played a major role in the Meccan religious cult. No iconic representation of Allah is known to have existed. Muhammad's father's name was ʿAbd-Allāh meaning "the slave of Allāh". === Christianity === The Aramaic word for "God" in the language of Assyrian Christians is ʼĔlāhā, or Alaha. Arabic-speakers of all Abrahamic faiths, including Christians and Jews, use the word "Allah" to mean "God". The Christian Arabs of today have no other word for "God" than "Allah". (Even the Arabic-descended Maltese language of Malta, whose population is almost entirely Roman Catholic, uses Alla for "God".) Arab Christians, for example, use the terms Allāh al-ab (الله الأب) for God the Father, Allāh al-ibn (الله الابن) for God the Son, and Allāh al-rūḥ al-quds (الله الروح القدس) for God the Holy Spirit. (See God in Christianity for the Christian concept of God.) Arab Christians have used two forms of invocations that were affixed to the beginning of their written works. They adopted the Muslim bismillāh, and also created their own Trinitized bismillāh as early as the 8th century. The Muslim bismillāh reads: "In the name of God, the Compassionate, the Merciful." The Trinitized bismillāh reads: "In the name of Father and the Son and the Holy Spirit, One God." The Syriac, Latin and Greek invocations do not have the words "One God" at the end. This addition was made to emphasize the monotheistic aspect of Trinitarian belief and also to make it more palatable to Muslims.According to Marshall Hodgson, it seems that in the pre-Islamic times, some Arab Christians made pilgrimage to the Kaaba, a pagan temple at that time, honoring Allah there as God the Creator.Some archaeological excavation quests have led to the discovery of ancient pre-Islamic inscriptions and tombs made by Arab Christians in the ruins of a church at Umm el-Jimal in Northern Jordan, which contained references to Allah as the proper name of God, and some of the graves contained names such as "Abd Allah" which means "the servant/slave of Allah".The name Allah can be found countless times in the reports and the lists of names of Christian martyrs in South Arabia, as reported by antique Syriac documents of the names of those martyrs from the era of the Himyarite and Aksumite kingdomsA Christian leader named Abd Allah ibn Abu Bakr ibn Muhammad was martyred in Najran in 523, as he had worn a ring that said "Allah is my lord".In an inscription of Christian martyrion dated back to 512, references to Allah can be found in both Arabic and Aramaic, which called him "Allah" and "Alaha", and the inscription starts with the statement "By the Help of Allah".In pre-Islamic Gospels, the name used for God was "Allah", as evidenced by some discovered Arabic versions of the New Testament written by Arab Christians during the pre-Islamic era in Northern and Southern Arabia.Pre-Islamic Arab Christians have been reported to have raised the battle cry "Ya La Ibad Allah" (O slaves of Allah) to invoke each other into battle."Allah" was also mentioned in pre-Islamic Christian poems by some Ghassanid and Tanukhid poets in Syria and Northern Arabia. === Islam === In Islam, Allah is the unique, omnipotent and only deity and creator of the universe and is equivalent to God in other Abrahamic religions.According to Islamic belief, Allah is the most common word to represent God, and humble submission to his will, divine ordinances and commandments is the pivot of the Muslim faith. "He is the only God, creator of the universe, and the judge of humankind." "He is unique (wāḥid) and inherently one (aḥad), all-merciful and omnipotent." The Qur'an declares "the reality of Allah, His inaccessible mystery, His various names, and His actions on behalf of His creatures."In Islamic tradition, there are 99 Names of God (al-asmā’ al-ḥusná lit. meaning: 'the best names' or 'the most beautiful names'), each of which evoke a distinct characteristic of Allah. All these names refer to Allah, the supreme and all-comprehensive divine name. Among the 99 names of God, the most famous and most frequent of these names are "the Merciful" (al-Raḥmān) and "the Compassionate" (al-Raḥīm).Most Muslims use the untranslated Arabic phrase in shā’ Allāh (meaning 'if God wills') after references to future events. Muslim discursive piety encourages beginning things with the invocation of bismillāh (meaning 'in the name of God').There are certain phrases in praise of God that are favored by Muslims, including "Subḥān Allāh" (Holiness be to God), "al-ḥamdu lillāh" (Praise be to God), "lā ilāha illā Allāh" (There is no deity but God) and "Allāhu akbar" (God is greater) as a devotional exercise of remembering God (dhikr). In a Sufi practice known as dhikr Allah (lit. remembrance of God), the Sufi repeats and contemplates on the name Allah or other divine names while controlling his or her breath.According to Gerhard Böwering, in contrast with pre-Islamic Arabian polytheism, God in Islam does not have associates and companions, nor is there any kinship between God and jinn. Pre-Islamic pagan Arabs believed in a blind, powerful, inexorable and insensible fate over which man had no control. This was replaced with the Islamic notion of a powerful but provident and merciful God.According to Francis Edward Peters, "The Qur’ān insists, Muslims believe, and historians affirm that Muhammad and his followers worship the same God as the Jews (29:46). The Qur’an's Allah is the same Creator God who covenanted with Abraham". Peters states that the Qur'an portrays Allah as both more powerful and more remote than Yahweh, and as a universal deity, unlike Yahweh who closely follows Israelites. == Pronunciation of the word Allah == In order to pronounce the word Allah correctly, one has to focus on the second “l” (ل) in Allah (الله). When the word Allah is preceded by the vowel “a” (فَتْحة) or the vowel “u” (ضَمّة), then the Lām is pronounced in a distinct heavy manner – with Tafkhīm. This heavy Lām is thus articulated with the entire body of the tongue rather than its tip alone. For example, verse 58:22: “man haddaAllah” (ِمَنْ حَادَّ الله) which means: those who oppose Allah.If, however, the preceding vowel is “i” (كَسْرة), then the Lām in Allah is light, such as in the Basmala: Bismillahi… (ِبِسْمِ الله الرَّحْمٰنِ الرَّحِيمِ). So if a Muslim says “Bismillahi”, he should not pronounce the Lām with a heavy emphasis – instead, just with the tip of the tongue. == As a loanword == === English and other European languages === The history of the name Allāh in English was probably influenced by the study of comparative religion in the 19th century; for example, Thomas Carlyle (1840) sometimes used the term Allah but without any implication that Allah was anything different from God. However, in his biography of Muḥammad (1934), Tor Andræ always used the term Allah, though he allows that this "conception of God" seems to imply that it is different from that of the Jewish and Christian theologies.Languages which may not commonly use the term Allah to denote God may still contain popular expressions which use the word. For example, because of the centuries long Muslim presence in the Iberian Peninsula, the word ojalá in the Spanish language and oxalá in the Portuguese language exist today, borrowed from Arabic (Arabic: إن شاء الله). This phrase literally means 'if God wills' (in the sense of "I hope so"). The German poet Mahlmann used the form "Allah" as the title of a poem about the ultimate deity, though it is unclear how much Islamic thought he intended to convey. Some Muslims leave the name "Allāh" untranslated in English. The word has also been applied to certain living human beings as personifications of the term and concept. === Malaysian and Indonesian language === Christians in Malaysia and Indonesia use Allah to refer to God in the Malaysian and Indonesian languages (both of them standardized forms of the Malay language). Mainstream Bible translations in the language use Allah as the translation of Hebrew Elohim (translated in English Bibles as "God"). This goes back to early translation work by Francis Xavier in the 16th century. The first dictionary of Dutch-Malay by Albert Cornelius Ruyl, Justus Heurnius, and Caspar Wiltens in 1650 (revised edition from 1623 edition and 1631 Latin edition) recorded "Allah" as the translation of the Dutch word "Godt". Ruyl also translated the Gospel of Matthew in 1612 into the Malay language (an early Bible translation into a non-European language, made a year after the publication of the King James Version), which was printed in the Netherlands in 1629. Then he translated the Gospel of Mark, published in 1638.The government of Malaysia in 2007 outlawed usage of the term Allah in any other but Muslim contexts, but the Malayan High Court in 2009 revoked the law, ruling it unconstitutional. While Allah had been used for the Christian God in Malay for more than four centuries, the contemporary controversy was triggered by usage of Allah by the Roman Catholic newspaper The Herald. The government appealed the court ruling, and the High Court suspended implementation of its verdict until the hearing of the appeal. In October 2013 the court ruled in favor of the government's ban. In early 2014 the Malaysian government confiscated more than 300 bibles for using the word to refer to the Christian God in Peninsular Malaysia. However, the use of Allah is not prohibited in the two Malaysian states of Sabah and Sarawak. The main reason it is not prohibited in these two states is that usage has been long-established and local Alkitab (Bibles) have been widely distributed freely in East Malaysia without restrictions for years. Both states also do not have similar Islamic state laws as those in West Malaysia.In reaction to some media criticism, the Malaysian government has introduced a "10-point solution" to avoid confusion and misleading information. The 10-point solution is in line with the spirit of the 18- and 20-point agreements of Sarawak and Sabah. === In other scripts and languages === Allāh in other languages that use Arabic script is spelled in the same way. This includes Urdu, Persian/Dari, Uyghur among others. Assamese, Bengali: আল্লাহ Allah Bosnian: Allah Chinese (Mandarin): 真主 Zhēnzhǔ (semantic translation as "the true lord"), 安拉 Ānlā, 阿拉 Ālā; or 胡大 Húdà (Khoda, from Farsi: خدا "God") Czech, Slovak: Alláh Greek: Αλλάχ Allách Filipino: Alā or Allah Hebrew: אללה‬ Allah Hindi: अल्लाह Allāh Malayalam: അള്ളാഹ് Aḷḷāh Japanese: アラー Arā, アッラー Arrā, アッラーフ Arrāfu Latvian: Allāhs Maltese: Alla Korean: 알라 Alla Polish: Allah, also archaic Allach or Ałłach Russian, Ukrainian, Bulgarian: Алла́х Allakh Serbian, Belarusian, Macedonian: Алах Alah Spanish, Portuguese: Alá Sylheti: আল্লা Alla Tamil: அல்லாஹ் Thai: อัลลอฮ์ Anláw Punjabi (Gurmukhi): ਅੱਲਾਹ Allāh, archaic ਅਲਹੁ Alahu (in Sikh scriptures) Turkish: Allah Vietnamese: Thánh A-la == Typography == The word Allāh is always written without an alif to spell the ā vowel. This is because the spelling was settled before Arabic spelling started habitually using alif to spell ā. However, in vocalized spelling, a small diacritic alif is added on top of the shaddah to indicate the pronunciation. One exception may be in the pre-Islamic Zabad inscription, where it ends with an ambiguous sign that may be a lone-standing h with a lengthened start, or may be a non-standard conjoined l-h:- الاه: This reading would be Allāh spelled phonetically with alif for the ā. الإله: This reading would be al-Ilāh = 'the god' (an older form, without contraction), by older spelling practice without alif for ā.Many Arabic type fonts feature special ligatures for Allah. === Unicode === Unicode has a code point reserved for Allāh, ﷲ‬ = U+FDF2, in the Arabic Presentation Forms-A block, which exists solely for "compatibility with some older, legacy character sets that encoded presentation forms directly"; this is discouraged for new text. Instead, the word Allāh should be represented by its individual Arabic letters, while modern font technologies will render the desired ligature. The calligraphic variant of the word used as the Coat of arms of Iran is encoded in Unicode, in the Miscellaneous Symbols range, at code point U+262B (☫). == See also == Allah as a lunar deity Abdullah (name) Ahura Mazda Brahman Elohim Yahweh Names of God == Notes == == References == The Unicode Consortium, Unicode Standard 5.0, Addison-Wesley, 2006, ISBN 978-0-321-48091-0, About the Unicode Standard Version 5.0 Book == External links == Names of Allah with Meaning on Website, Flash, and Mobile Phone Software Concept of God (Allah) in Islam The Concept of Allāh According to the Qur'an by Abdul Mannan Omar Allah, the Unique Name of GodTypographyArabic Fonts and Mac OS X Programs for Arabic in Mac OS X ### Answer: <Allah>, <Creator deities>, <God>, <Islamic theology>

### Instruction: retrieve labels for this: Art is a diverse range of human activities in creating visual, auditory or performing artifacts (artworks), expressing the author's imaginative, conceptual idea, or technical skill, intended to be appreciated for their beauty or emotional power. In their most general form these activities include the production of works of art, the criticism of art, the study of the history of art, and the aesthetic dissemination of art. Music, theatre, film, dance, and other performing arts, as well as literature and other media such as interactive media, are included in a broader definition of art or the arts. Until the 17th century, art referred to any skill or mastery and was not differentiated from crafts or sciences. In modern usage after the 17th century, where aesthetic considerations are paramount, the fine arts are separated and distinguished from acquired skills in general, such as the decorative or applied arts. Though the definition of what constitutes art is disputed and has changed over time, general descriptions mention an idea of imaginative or technical skill stemming from human agency and creation. The nature of art and related concepts, such as creativity and interpretation, are explored in a branch of philosophy known as aesthetics. == Creative art and fine art == In the perspective of the history of art, artistic works have existed for almost as long as humankind: from early pre-historic art to contemporary art; however, some theories restrict the concept of "artistic works" to modern Western societies. One early sense of the definition of art is closely related to the older Latin meaning, which roughly translates to "skill" or "craft," as associated with words such as "artisan." English words derived from this meaning include artifact, artificial, artifice, medical arts, and military arts. However, there are many other colloquial uses of the word, all with some relation to its etymology. Over time, philosophers like Plato, Aristotle, Socrates and Kant, among others, questioned the meaning of art. Several dialogues in Plato tackle questions about art: Socrates says that poetry is inspired by the muses, and is not rational. He speaks approvingly of this, and other forms of divine madness (drunkenness, eroticism, and dreaming) in the Phaedrus (265a–c), and yet in the Republic wants to outlaw Homer's great poetic art, and laughter as well. In Ion, Socrates gives no hint of the disapproval of Homer that he expresses in the Republic. The dialogue Ion suggests that Homer's Iliad functioned in the ancient Greek world as the Bible does today in the modern Christian world: as divinely inspired literary art that can provide moral guidance, if only it can be properly interpreted.With regards to the literary art and the musical arts, Aristotle considered epic poetry, tragedy, comedy, dithyrambic poetry and music to be mimetic or imitative art, each varying in imitation by medium, object, and manner. For example, music imitates with the media of rhythm and harmony, whereas dance imitates with rhythm alone, and poetry with language. The forms also differ in their object of imitation. Comedy, for instance, is a dramatic imitation of men worse than average; whereas tragedy imitates men slightly better than average. Lastly, the forms differ in their manner of imitation—through narrative or character, through change or no change, and through drama or no drama. Aristotle believed that imitation is natural to mankind and constitutes one of mankind's advantages over animals.The second, and more recent, sense of the word art as an abbreviation for creative art or fine art emerged in the early 17th century. Fine art refers to a skill used to express the artist's creativity, or to engage the audience's aesthetic sensibilities, or to draw the audience towards consideration of more refined or finer work of art. Within this latter sense, the word art may refer to several things: (i) a study of a creative skill, (ii) a process of using the creative skill, (iii) a product of the creative skill, or (iv) the audience's experience with the creative skill. The creative arts (art as discipline) are a collection of disciplines which produce artworks (art as objects) that are compelled by a personal drive (art as activity) and convey a message, mood, or symbolism for the perceiver to interpret (art as experience). Art is something that stimulates an individual's thoughts, emotions, beliefs, or ideas through the senses. Works of art can be explicitly made for this purpose or interpreted on the basis of images or objects. For some scholars, such as Kant, the sciences and the arts could be distinguished by taking science as representing the domain of knowledge and the arts as representing the domain of the freedom of artistic expression.Often, if the skill is being used in a common or practical way, people will consider it a craft instead of art. Likewise, if the skill is being used in a commercial or industrial way, it may be considered commercial art instead of fine art. On the other hand, crafts and design are sometimes considered applied art. Some art followers have argued that the difference between fine art and applied art has more to do with value judgments made about the art than any clear definitional difference. However, even fine art often has goals beyond pure creativity and self-expression. The purpose of works of art may be to communicate ideas, such as in politically, spiritually, or philosophically motivated art; to create a sense of beauty (see aesthetics); to explore the nature of perception; for pleasure; or to generate strong emotions. The purpose may also be seemingly nonexistent. The nature of art has been described by philosopher Richard Wollheim as "one of the most elusive of the traditional problems of human culture". Art has been defined as a vehicle for the expression or communication of emotions and ideas, a means for exploring and appreciating formal elements for their own sake, and as mimesis or representation. Art as mimesis has deep roots in the philosophy of Aristotle. Leo Tolstoy identified art as a use of indirect means to communicate from one person to another. Benedetto Croce and R.G. Collingwood advanced the idealist view that art expresses emotions, and that the work of art therefore essentially exists in the mind of the creator. The theory of art as form has its roots in the philosophy of Kant, and was developed in the early twentieth century by Roger Fry and Clive Bell. More recently, thinkers influenced by Martin Heidegger have interpreted art as the means by which a community develops for itself a medium for self-expression and interpretation. George Dickie has offered an institutional theory of art that defines a work of art as any artifact upon which a qualified person or persons acting on behalf of the social institution commonly referred to as "the art world" has conferred "the status of candidate for appreciation". Larry Shiner has described fine art as "not an essence or a fate but something we have made. Art as we have generally understood it is a European invention barely two hundred years old."Art may be characterized in terms of mimesis (its representation of reality), narrative (storytelling), expression, communication of emotion, or other qualities. During the Romantic period, art came to be seen as "a special faculty of the human mind to be classified with religion and science". == History == The oldest documented forms of art are visual arts, which include creation of images or objects in fields including today painting, sculpture, printmaking, photography, and other visual media. Sculptures, cave paintings, rock paintings and petroglyphs from the Upper Paleolithic dating to roughly 40,000 years ago have been found, but the precise meaning of such art is often disputed because so little is known about the cultures that produced them. The oldest art objects in the world—a series of tiny, drilled snail shells about 75,000 years old—were discovered in a South African cave. Containers that may have been used to hold paints have been found dating as far back as 100,000 years. Etched shells by Homo erectus from 430,000 and 540,000 years ago were discovered in 2014. Many great traditions in art have a foundation in the art of one of the great ancient civilizations: Ancient Egypt, Mesopotamia, Persia, India, China, Ancient Greece, Rome, as well as Inca, Maya, and Olmec. Each of these centers of early civilization developed a unique and characteristic style in its art. Because of the size and duration of these civilizations, more of their art works have survived and more of their influence has been transmitted to other cultures and later times. Some also have provided the first records of how artists worked. For example, this period of Greek art saw a veneration of the human physical form and the development of equivalent skills to show musculature, poise, beauty, and anatomically correct proportions.In Byzantine and Medieval art of the Western Middle Ages, much art focused on the expression of subjects about Biblical and religious culture, and used styles that showed the higher glory of a heavenly world, such as the use of gold in the background of paintings, or glass in mosaics or windows, which also presented figures in idealized, patterned (flat) forms. Nevertheless, a classical realist tradition persisted in small Byzantine works, and realism steadily grew in the art of Catholic Europe.Renaissance art had a greatly increased emphasis on the realistic depiction of the material world, and the place of humans in it, reflected in the corporeality of the human body, and development of a systematic method of graphical perspective to depict recession in a three-dimensional picture space. In the east, Islamic art's rejection of iconography led to emphasis on geometric patterns, calligraphy, and architecture. Further east, religion dominated artistic styles and forms too. India and Tibet saw emphasis on painted sculptures and dance, while religious painting borrowed many conventions from sculpture and tended to bright contrasting colors with emphasis on outlines. China saw the flourishing of many art forms: jade carving, bronzework, pottery (including the stunning terracotta army of Emperor Qin), poetry, calligraphy, music, painting, drama, fiction, etc. Chinese styles vary greatly from era to era and each one is traditionally named after the ruling dynasty. So, for example, Tang dynasty paintings are monochromatic and sparse, emphasizing idealized landscapes, but Ming dynasty paintings are busy and colorful, and focus on telling stories via setting and composition. Japan names its styles after imperial dynasties too, and also saw much interplay between the styles of calligraphy and painting. Woodblock printing became important in Japan after the 17th century. The western Age of Enlightenment in the 18th century saw artistic depictions of physical and rational certainties of the clockwork universe, as well as politically revolutionary visions of a post-monarchist world, such as Blake's portrayal of Newton as a divine geometer, or David's propagandistic paintings. This led to Romantic rejections of this in favor of pictures of the emotional side and individuality of humans, exemplified in the novels of Goethe. The late 19th century then saw a host of artistic movements, such as academic art, Symbolism, impressionism and fauvism among others.The history of twentieth-century art is a narrative of endless possibilities and the search for new standards, each being torn down in succession by the next. Thus the parameters of impressionism, Expressionism, Fauvism, Cubism, Dadaism, Surrealism, etc. cannot be maintained very much beyond the time of their invention. Increasing global interaction during this time saw an equivalent influence of other cultures into Western art. Thus, Japanese woodblock prints (themselves influenced by Western Renaissance draftsmanship) had an immense influence on impressionism and subsequent development. Later, African sculptures were taken up by Picasso and to some extent by Matisse. Similarly, in the 19th and 20th centuries the West has had huge impacts on Eastern art with originally western ideas like Communism and Post-Modernism exerting a powerful influence.Modernism, the idealistic search for truth, gave way in the latter half of the 20th century to a realization of its unattainability. Theodor W. Adorno said in 1970, "It is now taken for granted that nothing which concerns art can be taken for granted any more: neither art itself, nor art in relationship to the whole, nor even the right of art to exist." Relativism was accepted as an unavoidable truth, which led to the period of contemporary art and postmodern criticism, where cultures of the world and of history are seen as changing forms, which can be appreciated and drawn from only with skepticism and irony. Furthermore, the separation of cultures is increasingly blurred and some argue it is now more appropriate to think in terms of a global culture, rather than of regional ones.In The Origin of the Work of Art, Martin Heidegger, a German philosopher and a seminal thinker, describes the essence of art in terms of the concepts of being and truth. He argues that art is not only a way of expressing the element of truth in a culture, but the means of creating it and providing a springboard from which "that which is" can be revealed. Works of art are not merely representations of the way things are, but actually produce a community's shared understanding. Each time a new artwork is added to any culture, the meaning of what it is to exist is inherently changed. == Forms, genres, media, and styles == The creative arts are often divided into more specific categories, typically along perceptually distinguishable categories such as media, genre, styles, and form. Art form refers to the elements of art that are independent of its interpretation or significance. It covers the methods adopted by the artist and the physical composition of the artwork, primarily non-semantic aspects of the work (i.e., figurae), such as color, contour, dimension, medium, melody, space, texture, and value. Form may also include visual design principles, such as arrangement, balance, contrast, emphasis, harmony, proportion, proximity, and rhythm.In general there are three schools of philosophy regarding art, focusing respectively on form, content, and context. Extreme Formalism is the view that all aesthetic properties of art are formal (that is, part of the art form). Philosophers almost universally reject this view and hold that the properties and aesthetics of art extend beyond materials, techniques, and form. Unfortunately, there is little consensus on terminology for these informal properties. Some authors refer to subject matter and content – i.e., denotations and connotations – while others prefer terms like meaning and significance.Extreme Intentionalism holds that authorial intent plays a decisive role in the meaning of a work of art, conveying the content or essential main idea, while all other interpretations can be discarded. It defines the subject as the persons or idea represented, and the content as the artist's experience of that subject. For example, the composition of Napoleon I on his Imperial Throne is partly borrowed from the Statue of Zeus at Olympia. As evidenced by the title, the subject is Napoleon, and the content is Ingres's representation of Napoleon as "Emperor-God beyond time and space". Similarly to extreme formalism, philosophers typically reject extreme intentionalism, because art may have multiple ambiguous meanings and authorial intent may be unknowable and thus irrelevant. Its restrictive interpretation is "socially unhealthy, philosophically unreal, and politically unwise".Finally, the developing theory of post-structuralism studies art's significance in a cultural context, such as the ideas, emotions, and reactions prompted by a work. The cultural context often reduces to the artist's techniques and intentions, in which case analysis proceeds along lines similar to formalism and intentionalism. However, in other cases historical and material conditions may predominate, such as religious and philosophical convictions, sociopolitical and economic structures, or even climate and geography. Art criticism continues to grow and develop alongside art. === Skill and craft === Art can connote a sense of trained ability or mastery of a medium. Art can also simply refer to the developed and efficient use of a language to convey meaning with immediacy and or depth. Art can be defined as an act of expressing feelings, thoughts, and observations.There is an understanding that is reached with the material as a result of handling it, which facilitates one's thought processes. A common view is that the epithet "art", particular in its elevated sense, requires a certain level of creative expertise by the artist, whether this be a demonstration of technical ability, an originality in stylistic approach, or a combination of these two. Traditionally skill of execution was viewed as a quality inseparable from art and thus necessary for its success; for Leonardo da Vinci, art, neither more nor less than his other endeavors, was a manifestation of skill. Rembrandt's work, now praised for its ephemeral virtues, was most admired by his contemporaries for its virtuosity. At the turn of the 20th century, the adroit performances of John Singer Sargent were alternately admired and viewed with skepticism for their manual fluency, yet at nearly the same time the artist who would become the era's most recognized and peripatetic iconoclast, Pablo Picasso, was completing a traditional academic training at which he excelled.A common contemporary criticism of some modern art occurs along the lines of objecting to the apparent lack of skill or ability required in the production of the artistic object. In conceptual art, Marcel Duchamp's "Fountain" is among the first examples of pieces wherein the artist used found objects ("ready-made") and exercised no traditionally recognised set of skills. Tracey Emin's My Bed, or Damien Hirst's The Physical Impossibility of Death in the Mind of Someone Living follow this example and also manipulate the mass media. Emin slept (and engaged in other activities) in her bed before placing the result in a gallery as work of art. Hirst came up with the conceptual design for the artwork but has left most of the eventual creation of many works to employed artisans. Hirst's celebrity is founded entirely on his ability to produce shocking concepts. The actual production in many conceptual and contemporary works of art is a matter of assembly of found objects. However, there are many modernist and contemporary artists who continue to excel in the skills of drawing and painting and in creating hands-on works of art. == Purpose == Art has had a great number of different functions throughout its history, making its purpose difficult to abstract or quantify to any single concept. This does not imply that the purpose of Art is "vague", but that it has had many unique, different reasons for being created. Some of these functions of Art are provided in the following outline. The different purposes of art may be grouped according to those that are non-motivated, and those that are motivated (Lévi-Strauss). === Non-motivated functions === The non-motivated purposes of art are those that are integral to being human, transcend the individual, or do not fulfill a specific external purpose. In this sense, Art, as creativity, is something humans must do by their very nature (i.e., no other species creates art), and is therefore beyond utility. Basic human instinct for harmony, balance, rhythm. Art at this level is not an action or an object, but an internal appreciation of balance and harmony (beauty), and therefore an aspect of being human beyond utility."Imitation, then, is one instinct of our nature. Next, there is the instinct for 'harmony' and rhythm, meters being manifestly sections of rhythm. Persons, therefore, starting with this natural gift developed by degrees their special aptitudes, till their rude improvisations gave birth to Poetry." -Aristotle Experience of the mysterious. Art provides a way to experience one's self in relation to the universe. This experience may often come unmotivated, as one appreciates art, music or poetry."The most beautiful thing we can experience is the mysterious. It is the source of all true art and science." – Albert Einstein Expression of the imagination. Art provides a means to express the imagination in non-grammatic ways that are not tied to the formality of spoken or written language. Unlike words, which come in sequences and each of which have a definite meaning, art provides a range of forms, symbols and ideas with meanings that are malleable."Jupiter's eagle [as an example of art] is not, like logical (aesthetic) attributes of an object, the concept of the sublimity and majesty of creation, but rather something else—something that gives the imagination an incentive to spread its flight over a whole host of kindred representations that provoke more thought than admits of expression in a concept determined by words. They furnish an aesthetic idea, which serves the above rational idea as a substitute for logical presentation, but with the proper function, however, of animating the mind by opening out for it a prospect into a field of kindred representations stretching beyond its ken." -Immanuel Kant Ritualistic and symbolic functions. In many cultures, art is used in rituals, performances and dances as a decoration or symbol. While these often have no specific utilitarian (motivated) purpose, anthropologists know that they often serve a purpose at the level of meaning within a particular culture. This meaning is not furnished by any one individual, but is often the result of many generations of change, and of a cosmological relationship within the culture."Most scholars who deal with rock paintings or objects recovered from prehistoric contexts that cannot be explained in utilitarian terms and are thus categorized as decorative, ritual or symbolic, are aware of the trap posed by the term 'art'." -Silva Tomaskova === Motivated functions === Motivated purposes of art refer to intentional, conscious actions on the part of the artists or creator. These may be to bring about political change, to comment on an aspect of society, to convey a specific emotion or mood, to address personal psychology, to illustrate another discipline, to (with commercial arts) sell a product, or simply as a form of communication. Communication. Art, at its simplest, is a form of communication. As most forms of communication have an intent or goal directed toward another individual, this is a motivated purpose. Illustrative arts, such as scientific illustration, are a form of art as communication. Maps are another example. However, the content need not be scientific. Emotions, moods and feelings are also communicated through art."[Art is a set of] artefacts or images with symbolic meanings as a means of communication." – Steve Mithen Art as entertainment. Art may seek to bring about a particular emotion or mood, for the purpose of relaxing or entertaining the viewer. This is often the function of the art industries of Motion Pictures and Video Games. The Avante-Garde. Art for political change. One of the defining functions of early twentieth-century art has been to use visual images to bring about political change. Art movements that had this goal—Dadaism, Surrealism, Russian constructivism, and Abstract Expressionism, among others—are collectively referred to as the avante-garde arts."By contrast, the realistic attitude, inspired by positivism, from Saint Thomas Aquinas to Anatole France, clearly seems to me to be hostile to any intellectual or moral advancement. I loathe it, for it is made up of mediocrity, hate, and dull conceit. It is this attitude which today gives birth to these ridiculous books, these insulting plays. It constantly feeds on and derives strength from the newspapers and stultifies both science and art by assiduously flattering the lowest of tastes; clarity bordering on stupidity, a dog's life." – André Breton (Surrealism) Art as a "free zone", removed from the action of the social censure. Unlike the avant-garde movements, which wanted to erase cultural differences in order to produce new universal values, contemporary art has enhanced its tolerance towards cultural differences as well as its critical and liberating functions (social inquiry, activism, subversion, deconstruction ...), becoming a more open place for research and experimentation. Art for social inquiry, subversion and/or anarchy. While similar to art for political change, subversive or deconstructivist art may seek to question aspects of society without any specific political goal. In this case, the function of art may be simply to criticize some aspect of society. Graffiti art and other types of street art are graphics and images that are spray-painted or stencilled on publicly viewable walls, buildings, buses, trains, and bridges, usually without permission. Certain art forms, such as graffiti, may also be illegal when they break laws (in this case vandalism). Art for social causes. Art can be used to raise awareness for a large variety of causes. A number of art activities were aimed at raising awareness of autism, cancer, human trafficking, and a variety of other topics, such as ocean conservation, human rights in Darfur, murdered and missing Aboriginal women, elder abuse, and pollution. Trashion, using trash to make fashion, practiced by artists such as Marina DeBris is one example of using art to raise awareness about pollution. Art for psychological and healing purposes. Art is also used by art therapists, psychotherapists and clinical psychologists as art therapy. The Diagnostic Drawing Series, for example, is used to determine the personality and emotional functioning of a patient. The end product is not the principal goal in this case, but rather a process of healing, through creative acts, is sought. The resultant piece of artwork may also offer insight into the troubles experienced by the subject and may suggest suitable approaches to be used in more conventional forms of psychiatric therapy. Art for propaganda, or commercialism. Art is often utilized as a form of propaganda, and thus can be used to subtly influence popular conceptions or mood. In a similar way, art that tries to sell a product also influences mood and emotion. In both cases, the purpose of art here is to subtly manipulate the viewer into a particular emotional or psychological response toward a particular idea or object. Art as a fitness indicator. It has been argued that the ability of the human brain by far exceeds what was needed for survival in the ancestral environment. One evolutionary psychology explanation for this is that the human brain and associated traits (such as artistic ability and creativity) are the human equivalent of the peacock's tail. The purpose of the male peacock's extravagant tail has been argued to be to attract females (see also Fisherian runaway and handicap principle). According to this theory superior execution of art was evolutionary important because it attracted mates.The functions of art described above are not mutually exclusive, as many of them may overlap. For example, art for the purpose of entertainment may also seek to sell a product, i.e. the movie or video game. == Public access == Since ancient times, much of the finest art has represented a deliberate display of wealth or power, often achieved by using massive scale and expensive materials. Much art has been commissioned by political rulers or religious establishments, with more modest versions only available to the most wealthy in society.Nevertheless, there have been many periods where art of very high quality was available, in terms of ownership, across large parts of society, above all in cheap media such as pottery, which persists in the ground, and perishable media such as textiles and wood. In many different cultures, the ceramics of indigenous peoples of the Americas are found in such a wide range of graves that they were clearly not restricted to a social elite, though other forms of art may have been. Reproductive methods such as moulds made mass-production easier, and were used to bring high-quality Ancient Roman pottery and Greek Tanagra figurines to a very wide market. Cylinder seals were both artistic and practical, and very widely used by what can be loosely called the middle class in the Ancient Near East. Once coins were widely used, these also became an art form that reached the widest range of society.Another important innovation came in the 15th century in Europe, when printmaking began with small woodcuts, mostly religious, that were often very small and hand-colored, and affordable even by peasants who glued them to the walls of their homes. Printed books were initially very expensive, but fell steadily in price until by the 19th century even the poorest could afford some with printed illustrations. Popular prints of many different sorts have decorated homes and other places for centuries.Public buildings and monuments, secular and religious, by their nature normally address the whole of society, and visitors as viewers, and display to the general public has long been an important factor in their design. Egyptian temples are typical in that the most largest and most lavish decoration was placed on the parts that could be seen by the general public, rather than the areas seen only by the priests. Many areas of royal palaces, castles and the houses of the social elite were often generally accessible, and large parts of the art collections of such people could often be seen, either by anybody, or by those able to pay a small price, or those wearing the correct clothes, regardless of who they were, as at the Palace of Versailles, where the appropriate extra accessories (silver shoe buckles and a sword) could be hired from shops outside.Special arrangements were made to allow the public to see many royal or private collections placed in galleries, as with the Orleans Collection mostly housed in a wing of the Palais Royal in Paris, which could be visited for most of the 18th century. In Italy the art tourism of the Grand Tour became a major industry from the Renaissance onwards, and governments and cities made efforts to make their key works accessible. The British Royal Collection remains distinct, but large donations such as the Old Royal Library were made from it to the British Museum, established in 1753. The Uffizi in Florence opened entirely as a gallery in 1765, though this function had been gradually taking the building over from the original civil servants' offices for a long time before. The building now occupied by the Prado in Madrid was built before the French Revolution for the public display of parts of the royal art collection, and similar royal galleries open to the public existed in Vienna, Munich and other capitals. The opening of the Musée du Louvre during the French Revolution (in 1793) as a public museum for much of the former French royal collection certainly marked an important stage in the development of public access to art, transferring ownership to a republican state, but was a continuation of trends already well established.Most modern public museums and art education programs for children in schools can be traced back to this impulse to have art available to everyone. Museums in the United States tend to be gifts from the very rich to the masses. (The Metropolitan Museum of Art in New York City, for example, was created by John Taylor Johnston, a railroad executive whose personal art collection seeded the museum.) But despite all this, at least one of the important functions of art in the 21st century remains as a marker of wealth and social status. There have been attempts by artists to create art that can not be bought by the wealthy as a status object. One of the prime original motivators of much of the art of the late 1960s and 1970s was to create art that could not be bought and sold. It is "necessary to present something more than mere objects" said the major post war German artist Joseph Beuys. This time period saw the rise of such things as performance art, video art, and conceptual art. The idea was that if the artwork was a performance that would leave nothing behind, or was simply an idea, it could not be bought and sold. "Democratic precepts revolving around the idea that a work of art is a commodity impelled the aesthetic innovation which germinated in the mid-1960s and was reaped throughout the 1970s. Artists broadly identified under the heading of Conceptual art ... substituting performance and publishing activities for engagement with both the material and materialistic concerns of painted or sculptural form ... [have] endeavored to undermine the art object qua object."In the decades since, these ideas have been somewhat lost as the art market has learned to sell limited edition DVDs of video works, invitations to exclusive performance art pieces, and the objects left over from conceptual pieces. Many of these performances create works that are only understood by the elite who have been educated as to why an idea or video or piece of apparent garbage may be considered art. The marker of status becomes understanding the work instead of necessarily owning it, and the artwork remains an upper-class activity. "With the widespread use of DVD recording technology in the early 2000s, artists, and the gallery system that derives its profits from the sale of artworks, gained an important means of controlling the sale of video and computer artworks in limited editions to collectors." == Controversies == Art has long been controversial, that is to say disliked by some viewers, for a wide variety of reasons, though most pre-modern controversies are dimly recorded, or completely lost to a modern view. Iconoclasm is the destruction of art that is disliked for a variety of reasons, including religious ones. Aniconism is a general dislike of either all figurative images, or often just religious ones, and has been a thread in many major religions. It has been a crucial factor in the history of Islamic art, where depictions of Muhammad remain especially controversial. Much art has been disliked purely because it depicted or otherwise stood for unpopular rulers, parties or other groups. Artistic conventions have often been conservative and taken very seriously by art critics, though often much less so by a wider public. The iconographic content of art could cause controversy, as with late medieval depictions of the new motif of the Swoon of the Virgin in scenes of the Crucifixion of Jesus. The Last Judgment by Michelangelo was controversial for various reasons, including breaches of decorum through nudity and the Apollo-like pose of Christ.The content of much formal art through history was dictated by the patron or commissioner rather than just the artist, but with the advent of Romanticism, and economic changes in the production of art, the artists' vision became the usual determinant of the content of his art, increasing the incidence of controversies, though often reducing their significance. Strong incentives for perceived originality and publicity also encouraged artists to court controversy. Théodore Géricault's Raft of the Medusa (c. 1820), was in part a political commentary on a recent event. Édouard Manet's Le Déjeuner sur l'Herbe (1863), was considered scandalous not because of the nude woman, but because she is seated next to men fully dressed in the clothing of the time, rather than in robes of the antique world. John Singer Sargent's Madame Pierre Gautreau (Madam X) (1884), caused a controversy over the reddish pink used to color the woman's ear lobe, considered far too suggestive and supposedly ruining the high-society model's reputation. The gradual abandonment of naturalism and the depiction of realistic representations of the visual appearance of subjects in the 19th and 20th centuries led to a rolling controversy lasting for over a century. In the twentieth century, Pablo Picasso's Guernica (1937) used arresting cubist techniques and stark monochromatic oils, to depict the harrowing consequences of a contemporary bombing of a small, ancient Basque town. Leon Golub's Interrogation III (1981), depicts a female nude, hooded detainee strapped to a chair, her legs open to reveal her sexual organs, surrounded by two tormentors dressed in everyday clothing. Andres Serrano's Piss Christ (1989) is a photograph of a crucifix, sacred to the Christian religion and representing Christ's sacrifice and final suffering, submerged in a glass of the artist's own urine. The resulting uproar led to comments in the United States Senate about public funding of the arts. == Theory == Before Modernism, aesthetics in Western art was greatly concerned with achieving the appropriate balance between different aspects of realism or truth to nature and the ideal; ideas as to what the appropriate balance is have shifted to and fro over the centuries. This concern is largely absent in other traditions of art. The aesthetic theorist John Ruskin, who championed what he saw as the naturalism of J. M. W. Turner, saw art's role as the communication by artifice of an essential truth that could only be found in nature.The definition and evaluation of art has become especially problematic since the 20th century. Richard Wollheim distinguishes three approaches to assessing the aesthetic value of art: the Realist, whereby aesthetic quality is an absolute value independent of any human view; the Objectivist, whereby it is also an absolute value, but is dependent on general human experience; and the Relativist position, whereby it is not an absolute value, but depends on, and varies with, the human experience of different humans. === Arrival of Modernism === The arrival of Modernism in the late nineteenth century lead to a radical break in the conception of the function of art, and then again in the late twentieth century with the advent of postmodernism. Clement Greenberg's 1960 article "Modernist Painting" defines modern art as "the use of characteristic methods of a discipline to criticize the discipline itself". Greenberg originally applied this idea to the Abstract Expressionist movement and used it as a way to understand and justify flat (non-illusionistic) abstract painting: Realistic, naturalistic art had dissembled the medium, using art to conceal art; modernism used art to call attention to art. The limitations that constitute the medium of painting—the flat surface, the shape of the support, the properties of the pigment—were treated by the Old Masters as negative factors that could be acknowledged only implicitly or indirectly. Under Modernism these same limitations came to be regarded as positive factors, and were acknowledged openly. After Greenberg, several important art theorists emerged, such as Michael Fried, T. J. Clark, Rosalind Krauss, Linda Nochlin and Griselda Pollock among others. Though only originally intended as a way of understanding a specific set of artists, Greenberg's definition of modern art is important to many of the ideas of art within the various art movements of the 20th century and early 21st century.Pop artists like Andy Warhol became both noteworthy and influential through work including and possibly critiquing popular culture, as well as the art world. Artists of the 1980s, 1990s, and 2000s expanded this technique of self-criticism beyond high art to all cultural image-making, including fashion images, comics, billboards and pornography.Duchamp once proposed that art is any activity of any kind- everything. However, the way that only certain activities are classified today as art is a social construction. There is evidence that there may be an element of truth to this. The Invention of Art: A Cultural History is an art history book which examines the construction of the modern system of the arts i.e. Fine Art. Shiner finds evidence that the older system of the arts before our modern system (fine art) held art to be any skilled human activity i.e. Ancient Greek society did not possess the term art but techne. Techne can be understood neither as art or craft, the reason being that the distinctions of art and craft are historical products that came later on in human history. Techne included painting, sculpting and music but also; cooking, medicine, horsemanship, geometry, carpentry, prophecy, and farming etc. === New Criticism and the "intentional fallacy" === Following Duchamp during the first half of the twentieth century, a significant shift to general aesthetic theory took place which attempted to apply aesthetic theory between various forms of art, including the literary arts and the visual arts, to each other. This resulted in the rise of the New Criticism school and debate concerning the intentional fallacy. At issue was the question of whether the aesthetic intentions of the artist in creating the work of art, whatever its specific form, should be associated with the criticism and evaluation of the final product of the work of art, or, if the work of art should be evaluated on its own merits independent of the intentions of the artist.In 1946, William K. Wimsatt and Monroe Beardsley published a classic and controversial New Critical essay entitled "The Intentional Fallacy", in which they argued strongly against the relevance of an author's intention, or "intended meaning" in the analysis of a literary work. For Wimsatt and Beardsley, the words on the page were all that mattered; importation of meanings from outside the text was considered irrelevant, and potentially distracting.In another essay, "The Affective Fallacy," which served as a kind of sister essay to "The Intentional Fallacy" Wimsatt and Beardsley also discounted the reader's personal/emotional reaction to a literary work as a valid means of analyzing a text. This fallacy would later be repudiated by theorists from the reader-response school of literary theory. Ironically, one of the leading theorists from this school, Stanley Fish, was himself trained by New Critics. Fish criticizes Wimsatt and Beardsley in his essay "Literature in the Reader" (1970).As summarized by Gaut and Livingston in their essay "The Creation of Art": "Structuralist and post-structuralists theorists and critics were sharply critical of many aspects of New Criticism, beginning with the emphasis on aesthetic appreciation and the so-called autonomy of art, but they reiterated the attack on biographical criticisms's assumption that the artist's activities and experience were a privileged critical topic." These authors contend that: "Anti-intentionalists, such as formalists, hold that the intentions involved in the making of art are irrelevant or peripheral to correctly interpreting art. So details of the act of creating a work, though possibly of interest in themselves, have no bearing on the correct interpretation of the work."Gaut and Livingston define the intentionalists as distinct from formalists stating that: "Intentionalists, unlike formalists, hold that reference to intentions is essential in fixing the correct interpretation of works." They quote Richard Wollheim as stating that, "The task of criticism is the reconstruction of the creative process, where the creative process must in turn be thought of as something not stopping short of, but terminating on, the work of art itself." === "Linguistic turn" and its debate === The end of the 20th century fostered an extensive debate known as the linguistic turn controversy, or the "innocent eye debate", and generally referred to as the structuralism-poststructuralism debate in the philosophy of art. This debate discussed the encounter of the work of art as being determined by the relative extent to which the conceptual encounter with the work of art dominates over the perceptual encounter with the work of art.Decisive for the linguistic turn debate in art history and the humanities were the works of yet another tradition, namely the structuralism of Ferdinand de Saussure and the ensuing movement of poststructuralism. In 1981, the artist Mark Tansey created a work of art titled "The Innocent Eye" as a criticism of the prevailing climate of disagreement in the philosophy of art during the closing decades of the 20th century. Influential theorists include Judith Butler, Luce Irigaray, Julia Kristeva, Michel Foucault and Jacques Derrida. The power of language, more specifically of certain rhetorical tropes, in art history and historical discourse was explored by Hayden White. The fact that language is not a transparent medium of thought had been stressed by a very different form of philosophy of language which originated in the works of Johann Georg Hamann and Wilhelm von Humboldt. Ernst Gombrich and Nelson Goodman in his book Languages of Art: An Approach to a Theory of Symbols came to hold that the conceptual encounter with the work of art predominated exclusively over the perceptual and visual encounter with the work of art during the 1960s and 1970s. He was challenged on the basis of research done by the Nobel prize winning psychologist Roger Sperry who maintained that the human visual encounter was not limited to concepts represented in language alone (the linguistic turn) and that other forms of psychological representations of the work of art were equally defensible and demonstrable. Sperry's view eventually prevailed by the end of the 20th century with aesthetic philosophers such as Nick Zangwill strongly defending a return to moderate aesthetic formalism among other alternatives. == Classification disputes == Disputes as to whether or not to classify something as a work of art are referred to as classificatory disputes about art. Classificatory disputes in the 20th century have included cubist and impressionist paintings, Duchamp's Fountain, the movies, superlative imitations of banknotes, conceptual art, and video games. Philosopher David Novitz has argued that disagreement about the definition of art are rarely the heart of the problem. Rather, "the passionate concerns and interests that humans vest in their social life" are "so much a part of all classificatory disputes about art" (Novitz, 1996). According to Novitz, classificatory disputes are more often disputes about societal values and where society is trying to go than they are about theory proper. For example, when the Daily Mail criticized Hirst's and Emin's work by arguing "For 1,000 years art has been one of our great civilising forces. Today, pickled sheep and soiled beds threaten to make barbarians of us all" they are not advancing a definition or theory about art, but questioning the value of Hirst's and Emin's work. In 1998, Arthur Danto, suggested a thought experiment showing that "the status of an artifact as work of art results from the ideas a culture applies to it, rather than its inherent physical or perceptible qualities. Cultural interpretation (an art theory of some kind) is therefore constitutive of an object's arthood."Anti-art is a label for art that intentionally challenges the established parameters and values of art; it is term associated with Dadaism and attributed to Marcel Duchamp just before World War I, when he was making art from found objects. One of these, Fountain (1917), an ordinary urinal, has achieved considerable prominence and influence on art. Anti-art is a feature of work by Situationist International, the lo-fi Mail art movement, and the Young British Artists, though it is a form still rejected by the Stuckists, who describe themselves as anti-anti-art.Architecture is often included as one of the visual arts; however, like the decorative arts, or advertising, it involves the creation of objects where the practical considerations of use are essential in a way that they usually are not in a painting, for example. === Value judgment === Somewhat in relation to the above, the word art is also used to apply judgments of value, as in such expressions as "that meal was a work of art" (the cook is an artist), or "the art of deception", (the highly attained level of skill of the deceiver is praised). It is this use of the word as a measure of high quality and high value that gives the term its flavor of subjectivity. Making judgments of value requires a basis for criticism. At the simplest level, a way to determine whether the impact of the object on the senses meets the criteria to be considered art is whether it is perceived to be attractive or repulsive. Though perception is always colored by experience, and is necessarily subjective, it is commonly understood that what is not somehow aesthetically satisfying cannot be art. However, "good" art is not always or even regularly aesthetically appealing to a majority of viewers. In other words, an artist's prime motivation need not be the pursuit of the aesthetic. Also, art often depicts terrible images made for social, moral, or thought-provoking reasons. For example, Francisco Goya's painting depicting the Spanish shootings of 3rd of May 1808 is a graphic depiction of a firing squad executing several pleading civilians. Yet at the same time, the horrific imagery demonstrates Goya's keen artistic ability in composition and execution and produces fitting social and political outrage. Thus, the debate continues as to what mode of aesthetic satisfaction, if any, is required to define 'art'.The assumption of new values or the rebellion against accepted notions of what is aesthetically superior need not occur concurrently with a complete abandonment of the pursuit of what is aesthetically appealing. Indeed, the reverse is often true, that the revision of what is popularly conceived of as being aesthetically appealing allows for a re-invigoration of aesthetic sensibility, and a new appreciation for the standards of art itself. Countless schools have proposed their own ways to define quality, yet they all seem to agree in at least one point: once their aesthetic choices are accepted, the value of the work of art is determined by its capacity to transcend the limits of its chosen medium to strike some universal chord by the rarity of the skill of the artist or in its accurate reflection in what is termed the zeitgeist. Art is often intended to appeal to and connect with human emotion. It can arouse aesthetic or moral feelings, and can be understood as a way of communicating these feelings. Artists express something so that their audience is aroused to some extent, but they do not have to do so consciously. Art may be considered an exploration of the human condition; that is, what it is to be human. == See also == == Notes == == Bibliography == Oscar Wilde, Intentions, 1891 Stephen Davies, Definitions of Art, 1991 Nina Felshin, ed.

### Instruction: retrieve labels for this: Agnostida is an order of arthropod which first developed near the end of the Early Cambrian period and thrived during the Middle Cambrian. They are present in the Lower Cambrian fossil record along with trilobites from the Redlichiida, Corynexochida, and Ptychopariida orders. The last agnostids went extinct in the Late Ordovician. == Systematics == The Agnostida are divided into two suborders — Agnostina and Eodiscina — which are then subdivided into a number of families. As a group, agnostids are isopygous, meaning their pygidium is similar in size and shape to their cephalon. Most agnostid species were eyeless. The systematic position of the order Agnostida within the class Trilobita remains uncertain, and there has been continuing debate whether they are trilobites or a stem group. The challenge to the status has focused on Agnostina partly due to the juveniles of one genus have been found with legs differing dramatically from those of adult trilobites, suggesting they are not members of the lamellipedian clade, of which trilobites are a part. Instead, the limbs of agnostids closely resemble those of stem group crustaceans, although they lack the proximal endite, which defines that group. They are likely the sister taxon to the crustacean stem lineage, and, as such, part of the clade, Crustaceomorpha. Other researchers have suggested, based on a cladistic analyses of dorsal exoskeletal features, that Eodiscina and Agnostida are closely united, and the Eodiscina descended from the trilobite order Ptychopariida. == Ecology == Scientists have long debated whether the agnostids lived a pelagic or a benthic lifestyle. Their lack of eyes, a morphology not well-suited for swimming, and their fossils found in association with other benthic trilobites suggest a benthic (bottom-dwelling) mode of life. They are likely to have lived on areas of the ocean floor which received little or no light and fed on detritus which descended from upper layers of the sea to the bottom. Their wide geographic dispersion in the fossil record is uncharacteristic of benthic animals, suggesting a pelagic existence. The thoracic segment appears to form a hinge between the head and pygidium allowing for a bivalved ostracodan-type lifestyle. The orientation of the thoracic appendages appears ill-suited for benthic living. Recent work suggests that some agnostids were benthic predators, engaging in cannibalism and possibly pack-hunting behavior.They are sometimes preserved within the voids of other organisms, for instance within empty hyolith conchs, within sponges, worm tubes and under the carapaces of bivalved arthropods, presumably in order to hide from predators or strong storm currents; or maybe whilst scavenging for food. In the case of the tapering worm tubes Selkirkia, trilobites are always found with their heads directed towards the opening of the tube, suggesting that they reversed in; the absence of any moulted carapaces suggests that moulting was not their primary reason for seeking shelter. == References == == External links == Order Agnostida by Sam Gon III.

### Instruction: retrieve labels for this: The ampere (; symbol: A), often shortened to "amp", is the base unit of electric current in the International System of Units (SI). It is named after André-Marie Ampère (1775–1836), French mathematician and physicist, considered the father of electrodynamics. The International System of Units defines the ampere in terms of other base units by measuring the electromagnetic force between electrical conductors carrying electric current. The earlier CGS measurement system had two different definitions of current, one essentially the same as the SI's and the other using electric charge as the base unit, with the unit of charge defined by measuring the force between two charged metal plates. The ampere was then defined as one coulomb of charge per second. In SI, the unit of charge, the coulomb, is defined as the charge carried by one ampere during one second. == Definition == SI defines ampere as follows: The ampere is that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross-section, and placed one metre apart in vacuum, would produce between these conductors a force equal to 2×10−7 newtons per metre of length. Ampère's force law states that there is an attractive or repulsive force between two parallel wires carrying an electric current. This force is used in the formal definition of the ampere. The SI unit of charge, the coulomb, "is the quantity of electricity carried in 1 second by a current of 1 ampere". Conversely, a current of one ampere is one coulomb of charge going past a given point per second: 1 A = 1 C s . {\displaystyle {\rm {1\ A=1{\tfrac {C}{s}}.}}} In general, charge Q is determined by steady current I flowing for a time t as Q = It. Constant, instantaneous and average current are expressed in amperes (as in "the charging current is 1.2 A") and the charge accumulated, or passed through a circuit over a period of time is expressed in coulombs (as in "the battery charge is 30000 C"). The relation of the ampere (C/s) to the coulomb is the same as that of the watt (J/s) to the joule. == History == The ampere was originally defined as one tenth of the unit of electric current in the centimetre–gram–second system of units. That unit, now known as the abampere, was defined as the amount of current that generates a force of two dynes per centimetre of length between two wires one centimetre apart. The size of the unit was chosen so that the units derived from it in the MKSA system would be conveniently sized. The "international ampere" was an early realization of the ampere, defined as the current that would deposit 0.001118 grams of silver per second from a silver nitrate solution. Later, more accurate measurements revealed that this current is 0.99985 A. Since power is defined as the product of current and voltage, the ampere can alternatively be expressed in terms of the other units using the relationship I=P/V, and thus 1 ampere equals 1 W/V. == Realization == The standard ampere is most accurately realized using a Kibble balance, but is in practice maintained via Ohm's law from the units of electromotive force and resistance, the volt and the ohm, since the latter two can be tied to physical phenomena that are relatively easy to reproduce, the Josephson junction and the quantum Hall effect, respectively.At present, techniques to establish the realization of an ampere have a relative uncertainty of approximately a few parts in 107, and involve realizations of the watt, the ohm and the volt. == Proposed future definition == Rather than a definition in terms of the force between two current-carrying wires, it has been proposed that the ampere should be defined in terms of the rate of flow of elementary charges. Since a coulomb is approximately equal to 6.2415093×1018 elementary charges (such as those carried by protons, or the negative of those carried by electrons), one ampere is approximately equivalent to 6.2415093×1018 elementary charges moving past a boundary in one second. (6.2415093×1018 is the reciprocal of the value of the elementary charge in coulombs.) The proposed change would define 1 A as being the current in the direction of flow of a particular number of elementary charges per second. In 2005, the International Committee for Weights and Measures (CIPM) agreed to study the proposed change. The new definition was discussed at the 25th General Conference on Weights and Measures (CGPM) in 2014 but for the time being was not adopted. == Everyday examples == The current drawn by typical constant-voltage energy distribution systems is usually dictated by the power (watt) consumed by the system and the operating voltage. For this reason the examples given below are grouped by voltage level. === CPUs – 1 V DC === Current Notebook CPUs (up to 15...45 W at 1 V): up to 15...45 A Current High End CPUs (up to 65...140 W at 1,15 V): up to 55...120 A === Portable devices === Hearing aid (typically 1 mW at 1.4 V): 700 µA USB charging adapter (as power supply - typically 10 W at 5 V): 2 A === Internal combustion engine vehicles – 12 V DC === A typical motor vehicle has a 12 V battery.

For the same amount of power (in watts), the current drawn by a particular European or Commonwealth appliance (in Europe or a Commonwealth country) will be less than for an equivalent North American appliance. Typical circuit breakers will provide 16 A.

### Instruction: retrieve labels for this: In mathematics and computer science, an algorithm ( ( listen)) is an unambiguous specification of how to solve a class of problems. Algorithms can perform calculation, data processing and automated reasoning tasks. As an effective method, an algorithm can be expressed within a finite amount of space and time and in a well-defined formal language for calculating a function. Starting from an initial state and initial input (perhaps empty), the instructions describe a computation that, when executed, proceeds through a finite number of well-defined successive states, eventually producing "output" and terminating at a final ending state. The transition from one state to the next is not necessarily deterministic; some algorithms, known as randomized algorithms, incorporate random input.The concept of algorithm has existed for centuries and the use of the concept can be ascribed to Greek mathematicians, e.g. the sieve of Eratosthenes and Euclid's algorithm; the term algorithm itself derives from the 9th Century mathematician Muḥammad ibn Mūsā al'Khwārizmī, latinized 'Algoritmi'. A partial formalization of what would become the modern notion of algorithm began with attempts to solve the Entscheidungsproblem (the "decision problem") posed by David Hilbert in 1928. Subsequent formalizations were framed as attempts to define "effective calculability" or "effective method"; those formalizations included the Gödel–Herbrand–Kleene recursive functions of 1930, 1934 and 1935, Alonzo Church's lambda calculus of 1936, Emil Post's Formulation 1 of 1936, and Alan Turing's Turing machines of 1936–7 and 1939. == Etymology == The word 'algorithm' has its roots in latinizing the name of Muhammad ibn Musa al-Khwarizmi in a first step to algorismus. Al-Khwārizmī (Persian: خوارزمی‎, c. 780–850) was a Persian mathematician, astronomer, geographer, and scholar in the House of Wisdom in Baghdad, whose name means 'the native of Khwarezm', a region that was part of Greater Iran and is now in Uzbekistan.About 825, al-Khwarizmi wrote an Arabic language treatise on the Hindu–Arabic numeral system, which was translated into Latin during the 12th century under the title Algoritmi de numero Indorum. This title means "Algoritmi on the numbers of the Indians", where "Algoritmi" was the translator's Latinization of Al-Khwarizmi's name. Al-Khwarizmi was the most widely read mathematician in Europe in the late Middle Ages, primarily through another of his books, the Algebra. In late medieval Latin, algorismus, English 'algorism', the corruption of his name, simply meant the "decimal number system". In the 15th century, under the influence of the Greek word ἀριθμός 'number' (cf. 'arithmetic'), the Latin word was altered to algorithmus, and the corresponding English term 'algorithm' is first attested in the 17th century; the modern sense was introduced in the 19th century.In English, it was first used in about 1230 and then by Chaucer in 1391. English adopted the French term, but it wasn't until the late 19th century that "algorithm" took on the meaning that it has in modern English. Another early use of the word is from 1240, in a manual titled Carmen de Algorismo composed by Alexandre de Villedieu. It begins thus: Haec algorismus ars praesens dicitur, in qua / Talibus Indorum fruimur bis quinque figuris. which translates as: Algorism is the art by which at present we use those Indian figures, which number two times five. The poem is a few hundred lines long and summarizes the art of calculating with the new style of Indian dice, or Talibus Indorum, or Hindu numerals. == Informal definition == An informal definition could be "a set of rules that precisely defines a sequence of operations." which would include all computer programs, including programs that do not perform numeric calculations. Generally, a program is only an algorithm if it stops eventually.A prototypical example of an algorithm is the Euclidean algorithm to determine the maximum common divisor of two integers; an example (there are others) is described by the flowchart above and as an example in a later section. Boolos, Jeffrey & 1974, 1999 offer an informal meaning of the word in the following quotation: No human being can write fast enough, or long enough, or small enough† ( †"smaller and smaller without limit ...you'd be trying to write on molecules, on atoms, on electrons") to list all members of an enumerably infinite set by writing out their names, one after another, in some notation. But humans can do something equally useful, in the case of certain enumerably infinite sets: They can give explicit instructions for determining the nth member of the set, for arbitrary finite n. Such instructions are to be given quite explicitly, in a form in which they could be followed by a computing machine, or by a human who is capable of carrying out only very elementary operations on symbols. An "enumerably infinite set" is one whose elements can be put into one-to-one correspondence with the integers. Thus, Boolos and Jeffrey are saying that an algorithm implies instructions for a process that "creates" output integers from an arbitrary "input" integer or integers that, in theory, can be arbitrarily large. Thus an algorithm can be an algebraic equation such as y = m + n – two arbitrary "input variables" m and n that produce an output y. But various authors' attempts to define the notion indicate that the word implies much more than this, something on the order of (for the addition example): Precise instructions (in language understood by "the computer") for a fast, efficient, "good" process that specifies the "moves" of "the computer" (machine or human, equipped with the necessary internally contained information and capabilities) to find, decode, and then process arbitrary input integers/symbols m and n, symbols + and = ... and "effectively" produce, in a "reasonable" time, output-integer y at a specified place and in a specified format.The concept of algorithm is also used to define the notion of decidability. That notion is central for explaining how formal systems come into being starting from a small set of axioms and rules. In logic, the time that an algorithm requires to complete cannot be measured, as it is not apparently related with our customary physical dimension. From such uncertainties, that characterize ongoing work, stems the unavailability of a definition of algorithm that suits both concrete (in some sense) and abstract usage of the term. == Formalization == Algorithms are essential to the way computers process data. Many computer programs contain algorithms that detail the specific instructions a computer should perform (in a specific order) to carry out a specified task, such as calculating employees' paychecks or printing students' report cards. Thus, an algorithm can be considered to be any sequence of operations that can be simulated by a Turing-complete system. Authors who assert this thesis include Minsky (1967), Savage (1987) and Gurevich (2000): Minsky: "But we will also maintain, with Turing . . . that any procedure which could "naturally" be called effective, can in fact be realized by a (simple) machine. Although this may seem extreme, the arguments . . . in its favor are hard to refute". Gurevich: "...Turing's informal argument in favor of his thesis justifies a stronger thesis: every algorithm can be simulated by a Turing machine ... according to Savage [1987], an algorithm is a computational process defined by a Turing machine". Typically, when an algorithm is associated with processing information, data can be read from an input source, written to an output device and stored for further processing. Stored data are regarded as part of the internal state of the entity performing the algorithm. In practice, the state is stored in one or more data structures. For some such computational process, the algorithm must be rigorously defined: specified in the way it applies in all possible circumstances that could arise. That is, any conditional steps must be systematically dealt with, case-by-case; the criteria for each case must be clear (and computable). Because an algorithm is a precise list of precise steps, the order of computation is always crucial to the functioning of the algorithm. Instructions are usually assumed to be listed explicitly, and are described as starting "from the top" and going "down to the bottom", an idea that is described more formally by flow of control. So far, this discussion of the formalization of an algorithm has assumed the premises of imperative programming. This is the most common conception, and it attempts to describe a task in discrete, "mechanical" means. Unique to this conception of formalized algorithms is the assignment operation, setting the value of a variable. It derives from the intuition of "memory" as a scratchpad. There is an example below of such an assignment. For some alternate conceptions of what constitutes an algorithm see functional programming and logic programming. === Expressing algorithms === Algorithms can be expressed in many kinds of notation, including natural languages, pseudocode, flowcharts, drakon-charts, programming languages or control tables (processed by interpreters). Natural language expressions of algorithms tend to be verbose and ambiguous, and are rarely used for complex or technical algorithms. Pseudocode, flowcharts, drakon-charts and control tables are structured ways to express algorithms that avoid many of the ambiguities common in natural language statements. Programming languages are primarily intended for expressing algorithms in a form that can be executed by a computer, but are often used as a way to define or document algorithms. There is a wide variety of representations possible and one can express a given Turing machine program as a sequence of machine tables (see more at finite-state machine, state transition table and control table), as flowcharts and drakon-charts (see more at state diagram), or as a form of rudimentary machine code or assembly code called "sets of quadruples" (see more at Turing machine). Representations of algorithms can be classed into three accepted levels of Turing machine description: 1 High-level description "...prose to describe an algorithm, ignoring the implementation details. At this level we do not need to mention how the machine manages its tape or head." 2 Implementation description "...prose used to define the way the Turing machine uses its head and the way that it stores data on its tape. At this level we do not give details of states or transition function." 3 Formal description Most detailed, "lowest level", gives the Turing machine's "state table".For an example of the simple algorithm "Add m+n" described in all three levels, see Algorithm#Examples. == Design == Algorithm design refers to a method or mathematical process for problem solving and engineering algorithms. The design of algorithms is part of many solution theories of operation research, such as dynamic programming and divide-and-conquer. Techniques for designing and implementing algorithm designs are also called algorithm design patterns, such as the template method pattern and decorator pattern. One of the most important aspects of algorithm design is creating an algorithm that has an efficient runtime, also known as its Big O. Typical steps in development of algorithms: Problem definition Development of a model Specification of algorithm Designing an algorithm Checking the correctness of algorithm Analysis of algorithm Implementation of algorithm Program testing Documentation preparation == Implementation == Most algorithms are intended to be implemented as computer programs. However, algorithms are also implemented by other means, such as in a biological neural network (for example, the human brain implementing arithmetic or an insect looking for food), in an electrical circuit, or in a mechanical device. == Computer algorithms == In computer systems, an algorithm is basically an instance of logic written in software by software developers to be effective for the intended "target" computer(s) to produce output from given (perhaps null) input. An optimal algorithm, even running in old hardware, would produce faster results than a non-optimal (higher time complexity) algorithm for the same purpose, running in more efficient hardware; that is why algorithms, like computer hardware, are considered technology. "Elegant" (compact) programs, "good" (fast) programs : The notion of "simplicity and elegance" appears informally in Knuth and precisely in Chaitin: Knuth: ". . .we want good algorithms in some loosely defined aesthetic sense. One criterion . . . is the length of time taken to perform the algorithm . . .. Other criteria are adaptability of the algorithm to computers, its simplicity and elegance, etc"Chaitin: " . . . a program is 'elegant,' by which I mean that it's the smallest possible program for producing the output that it does"Chaitin prefaces his definition with: "I'll show you can't prove that a program is 'elegant'"—such a proof would solve the Halting problem (ibid). Algorithm versus function computable by an algorithm: For a given function multiple algorithms may exist. This is true, even without expanding the available instruction set available to the programmer. Rogers observes that "It is . . . important to distinguish between the notion of algorithm, i.e. procedure and the notion of function computable by algorithm, i.e. mapping yielded by procedure. The same function may have several different algorithms".Unfortunately there may be a tradeoff between goodness (speed) and elegance (compactness)—an elegant program may take more steps to complete a computation than one less elegant. An example that uses Euclid's algorithm appears below. Computers (and computors), models of computation: A computer (or human "computor") is a restricted type of machine, a "discrete deterministic mechanical device" that blindly follows its instructions. Melzak's and Lambek's primitive models reduced this notion to four elements: (i) discrete, distinguishable locations, (ii) discrete, indistinguishable counters (iii) an agent, and (iv) a list of instructions that are effective relative to the capability of the agent.Minsky describes a more congenial variation of Lambek's "abacus" model in his "Very Simple Bases for Computability". Minsky's machine proceeds sequentially through its five (or six, depending on how one counts) instructions, unless either a conditional IF–THEN GOTO or an unconditional GOTO changes program flow out of sequence. Besides HALT, Minsky's machine includes three assignment (replacement, substitution) operations: ZERO (e.g. the contents of location replaced by 0: L ← 0), SUCCESSOR (e.g. L ← L+1), and DECREMENT (e.g. L ← L − 1). Rarely must a programmer write "code" with such a limited instruction set. But Minsky shows (as do Melzak and Lambek) that his machine is Turing complete with only four general types of instructions: conditional GOTO, unconditional GOTO, assignment/replacement/substitution, and HALT.Simulation of an algorithm: computer (computor) language: Knuth advises the reader that "the best way to learn an algorithm is to try it . . . immediately take pen and paper and work through an example". But what about a simulation or execution of the real thing? The programmer must translate the algorithm into a language that the simulator/computer/computor can effectively execute. Stone gives an example of this: when computing the roots of a quadratic equation the computor must know how to take a square root. If they don't, then the algorithm, to be effective, must provide a set of rules for extracting a square root.This means that the programmer must know a "language" that is effective relative to the target computing agent (computer/computor). But what model should be used for the simulation? Van Emde Boas observes "even if we base complexity theory on abstract instead of concrete machines, arbitrariness of the choice of a model remains. It is at this point that the notion of simulation enters". When speed is being measured, the instruction set matters. For example, the subprogram in Euclid's algorithm to compute the remainder would execute much faster if the programmer had a "modulus" instruction available rather than just subtraction (or worse: just Minsky's "decrement"). Structured programming, canonical structures: Per the Church–Turing thesis, any algorithm can be computed by a model known to be Turing complete, and per Minsky's demonstrations, Turing completeness requires only four instruction types—conditional GOTO, unconditional GOTO, assignment, HALT. Kemeny and Kurtz observe that, while "undisciplined" use of unconditional GOTOs and conditional IF-THEN GOTOs can result in "spaghetti code", a programmer can write structured programs using only these instructions; on the other hand "it is also possible, and not too hard, to write badly structured programs in a structured language". Tausworthe augments the three Böhm-Jacopini canonical structures: SEQUENCE, IF-THEN-ELSE, and WHILE-DO, with two more: DO-WHILE and CASE. An additional benefit of a structured program is that it lends itself to proofs of correctness using mathematical induction.Canonical flowchart symbols: The graphical aide called a flowchart offers a way to describe and document an algorithm (and a computer program of one). Like program flow of a Minsky machine, a flowchart always starts at the top of a page and proceeds down. Its primary symbols are only four: the directed arrow showing program flow, the rectangle (SEQUENCE, GOTO), the diamond (IF-THEN-ELSE), and the dot (OR-tie). The Böhm–Jacopini canonical structures are made of these primitive shapes. Sub-structures can "nest" in rectangles, but only if a single exit occurs from the superstructure. The symbols, and their use to build the canonical structures, are shown in the diagram. == Examples == === Algorithm example === One of the simplest algorithms is to find the largest number in a list of numbers of random order. Finding the solution requires looking at every number in the list. From this follows a simple algorithm, which can be stated in a high-level description English prose, as: High-level description: If there are no numbers in the set then there is no highest number. Assume the first number in the set is the largest number in the set. For each remaining number in the set: if this number is larger than the current largest number, consider this number to be the largest number in the set. When there are no numbers left in the set to iterate over, consider the current largest number to be the largest number of the set.(Quasi-)formal description: Written in prose but much closer to the high-level language of a computer program, the following is the more formal coding of the algorithm in pseudocode or pidgin code: === Euclid's algorithm === Euclid's algorithm to compute the greatest common divisor (GCD) to two numbers appears as Proposition II in Book VII ("Elementary Number Theory") of his Elements. Euclid poses the problem thus: "Given two numbers not prime to one another, to find their greatest common measure". He defines "A number [to be] a multitude composed of units": a counting number, a positive integer not including zero. To "measure" is to place a shorter measuring length s successively (q times) along longer length l until the remaining portion r is less than the shorter length s. In modern words, remainder r = l − q×s, q being the quotient, or remainder r is the "modulus", the integer-fractional part left over after the division.For Euclid's method to succeed, the starting lengths must satisfy two requirements: (i) the lengths must not be zero, AND (ii) the subtraction must be “proper”; i.e., a test must guarantee that the smaller of the two numbers is subtracted from the larger (alternately, the two can be equal so their subtraction yields zero). Euclid's original proof adds a third requirement: the two lengths must not be prime to one another. Euclid stipulated this so that he could construct a reductio ad absurdum proof that the two numbers' common measure is in fact the greatest. While Nicomachus' algorithm is the same as Euclid's, when the numbers are prime to one another, it yields the number "1" for their common measure. So, to be precise, the following is really Nicomachus' algorithm. ==== Computer language for Euclid's algorithm ==== Only a few instruction types are required to execute Euclid's algorithm—some logical tests (conditional GOTO), unconditional GOTO, assignment (replacement), and subtraction. A location is symbolized by upper case letter(s), e.g. S, A, etc. The varying quantity (number) in a location is written in lower case letter(s) and (usually) associated with the location's name. For example, location L at the start might contain the number l = 3009. ==== An inelegant program for Euclid's algorithm ==== The following algorithm is framed as Knuth's four-step version of Euclid's and Nicomachus', but, rather than using division to find the remainder, it uses successive subtractions of the shorter length s from the remaining length r until r is less than s. The high-level description, shown in boldface, is adapted from Knuth 1973:2–4: INPUT: 1 [Into two locations L and S put the numbers l and s that represent the two lengths]: INPUT L, S 2 [Initialize R: make the remaining length r equal to the starting/initial/input length l]: R ← L E0: [Ensure r ≥ s.] 3 [Ensure the smaller of the two numbers is in S and the larger in R]: IF R > S THEN the contents of L is the larger number so skip over the exchange-steps 4, 5 and 6: GOTO step 6 ELSE swap the contents of R and S. 4 L ← R (this first step is redundant, but is useful for later discussion). 5 R ← S 6 S ← L E1: [Find remainder]: Until the remaining length r in R is less than the shorter length s in S, repeatedly subtract the measuring number s in S from the remaining length r in R. 7 IF S > R THEN done measuring so GOTO 10 ELSE measure again, 8 R ← R − S 9 [Remainder-loop]: GOTO 7. E2: [Is the remainder zero?]: EITHER (i) the last measure was exact, the remainder in R is zero, and the program can halt, OR (ii) the algorithm must continue: the last measure left a remainder in R less than measuring number in S. 10 IF R = 0 THEN done so GOTO step 15 ELSE CONTINUE TO step 11, E3: [Interchange s and r]: The nut of Euclid's algorithm. Use remainder r to measure what was previously smaller number s; L serves as a temporary location. 11 L ← R 12 R ← S 13 S ← L 14 [Repeat the measuring process]: GOTO 7 OUTPUT: 15 [Done. S contains the greatest common divisor]: PRINT S DONE: 16 HALT, END, STOP. ==== An elegant program for Euclid's algorithm ==== The following version of Euclid's algorithm requires only six core instructions to do what thirteen are required to do by "Inelegant"; worse, "Inelegant" requires more types of instructions. The flowchart of "Elegant" can be found at the top of this article. In the (unstructured) Basic language, the steps are numbered, and the instruction LET [] = [] is the assignment instruction symbolized by ←. The following version can be used with Object Oriented languages: How "Elegant" works: In place of an outer "Euclid loop", "Elegant" shifts back and forth between two "co-loops", an A > B loop that computes A ← A − B, and a B ≤ A loop that computes B ← B − A. This works because, when at last the minuend M is less than or equal to the subtrahend S ( Difference = Minuend − Subtrahend), the minuend can become s (the new measuring length) and the subtrahend can become the new r (the length to be measured); in other words the "sense" of the subtraction reverses. === Testing the Euclid algorithms === Does an algorithm do what its author wants it to do? A few test cases usually suffice to confirm core functionality. One source uses 3009 and 884. Knuth suggested 40902, 24140. Another interesting case is the two relatively prime numbers 14157 and 5950. But exceptional cases must be identified and tested. Will "Inelegant" perform properly when R > S, S > R, R = S? Ditto for "Elegant": B > A, A > B, A = B? (Yes to all). What happens when one number is zero, both numbers are zero? ("Inelegant" computes forever in all cases; "Elegant" computes forever when A = 0.) What happens if negative numbers are entered? Fractional numbers? If the input numbers, i.e. the domain of the function computed by the algorithm/program, is to include only positive integers including zero, then the failures at zero indicate that the algorithm (and the program that instantiates it) is a partial function rather than a total function. A notable failure due to exceptions is the Ariane 5 Flight 501 rocket failure (June 4, 1996). Proof of program correctness by use of mathematical induction: Knuth demonstrates the application of mathematical induction to an "extended" version of Euclid's algorithm, and he proposes "a general method applicable to proving the validity of any algorithm". Tausworthe proposes that a measure of the complexity of a program be the length of its correctness proof. === Measuring and improving the Euclid algorithms === Elegance (compactness) versus goodness (speed): With only six core instructions, "Elegant" is the clear winner, compared to "Inelegant" at thirteen instructions. However, "Inelegant" is faster (it arrives at HALT in fewer steps). Algorithm analysis indicates why this is the case: "Elegant" does two conditional tests in every subtraction loop, whereas "Inelegant" only does one. As the algorithm (usually) requires many loop-throughs, on average much time is wasted doing a "B = 0?" test that is needed only after the remainder is computed. Can the algorithms be improved?: Once the programmer judges a program "fit" and "effective"—that is, it computes the function intended by its author—then the question becomes, can it be improved? The compactness of "Inelegant" can be improved by the elimination of five steps. But Chaitin proved that compacting an algorithm cannot be automated by a generalized algorithm; rather, it can only be done heuristically; i.e., by exhaustive search (examples to be found at Busy beaver), trial and error, cleverness, insight, application of inductive reasoning, etc. Observe that steps 4, 5 and 6 are repeated in steps 11, 12 and 13. Comparison with "Elegant" provides a hint that these steps, together with steps 2 and 3, can be eliminated. This reduces the number of core instructions from thirteen to eight, which makes it "more elegant" than "Elegant", at nine steps. The speed of "Elegant" can be improved by moving the "B=0?" test outside of the two subtraction loops. This change calls for the addition of three instructions (B = 0?, A = 0?, GOTO). Now "Elegant" computes the example-numbers faster; whether this is always the case for any given A, B and R, S would require a detailed analysis. == Algorithmic analysis == It is frequently important to know how much of a particular resource (such as time or storage) is theoretically required for a given algorithm. Methods have been developed for the analysis of algorithms to obtain such quantitative answers (estimates); for example, the sorting algorithm above has a time requirement of O(n), using the big O notation with n as the length of the list. At all times the algorithm only needs to remember two values: the largest number found so far, and its current position in the input list. Therefore, it is said to have a space requirement of O(1), if the space required to store the input numbers is not counted, or O(n) if it is counted. Different algorithms may complete the same task with a different set of instructions in less or more time, space, or 'effort' than others. For example, a binary search algorithm (with cost O(log n) ) outperforms a sequential search (cost O(n) ) when used for table lookups on sorted lists or arrays. === Formal versus empirical === The analysis and study of algorithms is a discipline of computer science, and is often practiced abstractly without the use of a specific programming language or implementation. In this sense, algorithm analysis resembles other mathematical disciplines in that it focuses on the underlying properties of the algorithm and not on the specifics of any particular implementation. Usually pseudocode is used for analysis as it is the simplest and most general representation. However, ultimately, most algorithms are usually implemented on particular hardware / software platforms and their algorithmic efficiency is eventually put to the test using real code. For the solution of a "one off" problem, the efficiency of a particular algorithm may not have significant consequences (unless n is extremely large) but for algorithms designed for fast interactive, commercial or long life scientific usage it may be critical. Scaling from small n to large n frequently exposes inefficient algorithms that are otherwise benign. Empirical testing is useful because it may uncover unexpected interactions that affect performance. Benchmarks may be used to compare before/after potential improvements to an algorithm after program optimization. Empirical tests cannot replace formal analysis, though, and are not trivial to perform in a fair manner. === Execution efficiency === To illustrate the potential improvements possible even in well established algorithms, a recent significant innovation, relating to FFT algorithms (used heavily in the field of image processing), can decrease processing time up to 1,000 times for applications like medical imaging. In general, speed improvements depend on special properties of the problem, which are very common in practical applications. Speedups of this magnitude enable computing devices that make extensive use of image processing (like digital cameras and medical equipment) to consume less power. == Classification == There are various ways to classify algorithms, each with its own merits. === By implementation === One way to classify algorithms is by implementation means. Recursion A recursive algorithm is one that invokes (makes reference to) itself repeatedly until a certain condition (also known as termination condition) matches, which is a method common to functional programming. Iterative algorithms use repetitive constructs like loops and sometimes additional data structures like stacks to solve the given problems. Some problems are naturally suited for one implementation or the other. For example, towers of Hanoi is well understood using recursive implementation. Every recursive version has an equivalent (but possibly more or less complex) iterative version, and vice versa. Logical An algorithm may be viewed as controlled logical deduction. This notion may be expressed as: Algorithm = logic + control. The logic component expresses the axioms that may be used in the computation and the control component determines the way in which deduction is applied to the axioms. This is the basis for the logic programming paradigm. In pure logic programming languages the control component is fixed and algorithms are specified by supplying only the logic component. The appeal of this approach is the elegant semantics: a change in the axioms has a well-defined change in the algorithm. Serial, parallel or distributed Algorithms are usually discussed with the assumption that computers execute one instruction of an algorithm at a time. Those computers are sometimes called serial computers. An algorithm designed for such an environment is called a serial algorithm, as opposed to parallel algorithms or distributed algorithms. Parallel algorithms take advantage of computer architectures where several processors can work on a problem at the same time, whereas distributed algorithms utilize multiple machines connected with a computer network. Parallel or distributed algorithms divide the problem into more symmetrical or asymmetrical subproblems and collect the results back together. The resource consumption in such algorithms is not only processor cycles on each processor but also the communication overhead between the processors. Some sorting algorithms can be parallelized efficiently, but their communication overhead is expensive. Iterative algorithms are generally parallelizable. Some problems have no parallel algorithms, and are called inherently serial problems. Deterministic or non-deterministic Deterministic algorithms solve the problem with exact decision at every step of the algorithm whereas non-deterministic algorithms solve problems via guessing although typical guesses are made more accurate through the use of heuristics. Exact or approximate While many algorithms reach an exact solution, approximation algorithms seek an approximation that is closer to the true solution. Approximation can be reached by either using a deterministic or a random strategy. Such algorithms have practical value for many hard problems. One of the examples of an approximate algorithm is the Knapsack problem. The Knapsack problem is a problem where there is a set of given items. The goal of the problem is to pack the knapsack to get the maximum total value. Each item has some weight and some value. Total weight that we can carry is no more than some fixed number X. So, we must consider weights of items as well as their value. Quantum algorithm They run on a realistic model of quantum computation. The term is usually used for those algorithms which seem inherently quantum, or use some essential feature of quantum computation such as quantum superposition or quantum entanglement. === By design paradigm === Another way of classifying algorithms is by their design methodology or paradigm. There is a certain number of paradigms, each different from the other. Furthermore, each of these categories include many different types of algorithms. Some common paradigms are: Brute-force or exhaustive search This is the naive method of trying every possible solution to see which is best. Divide and conquer A divide and conquer algorithm repeatedly reduces an instance of a problem to one or more smaller instances of the same problem (usually recursively) until the instances are small enough to solve easily. One such example of divide and conquer is merge sorting. Sorting can be done on each segment of data after dividing data into segments and sorting of entire data can be obtained in the conquer phase by merging the segments. A simpler variant of divide and conquer is called a decrease and conquer algorithm, that solves an identical subproblem and uses the solution of this subproblem to solve the bigger problem. Divide and conquer divides the problem into multiple subproblems and so the conquer stage is more complex than decrease and conquer algorithms. An example of decrease and conquer algorithm is the binary search algorithm. Search and enumeration Many problems (such as playing chess) can be modeled as problems on graphs. A graph exploration algorithm specifies rules for moving around a graph and is useful for such problems. This category also includes search algorithms, branch and bound enumeration and backtracking. Randomized algorithm Such algorithms make some choices randomly (or pseudo-randomly). They can be very useful in finding approximate solutions for problems where finding exact solutions can be impractical (see heuristic method below). For some of these problems, it is known that the fastest approximations must involve some randomness. Whether randomized algorithms with polynomial time complexity can be the fastest algorithms for some problems is an open question known as the P versus NP problem. There are two large classes of such algorithms:Monte Carlo algorithms return a correct answer with high-probability. E.g. RP is the subclass of these that run in polynomial time. Las Vegas algorithms always return the correct answer, but their running time is only probabilistically bound, e.g. ZPP.Reduction of complexity This technique involves solving a difficult problem by transforming it into a better known problem for which we have (hopefully) asymptotically optimal algorithms. The goal is to find a reducing algorithm whose complexity is not dominated by the resulting reduced algorithm's. For example, one selection algorithm for finding the median in an unsorted list involves first sorting the list (the expensive portion) and then pulling out the middle element in the sorted list (the cheap portion). This technique is also known as transform and conquer. Back tracking In this approach multiple solutions are built incrementally and abandoned when it is determined that they cannot lead to a valid full solution. === Optimization problems === For optimization problems there is a more specific classification of algorithms; an algorithm for such problems may fall into one or more of the general categories described above as well as into one of the following: Linear programming When searching for optimal solutions to a linear function bound to linear equality and inequality constraints, the constraints of the problem can be used directly in producing the optimal solutions. There are algorithms that can solve any problem in this category, such as the popular simplex algorithm. Problems that can be solved with linear programming include the maximum flow problem for directed graphs. If a problem additionally requires that one or more of the unknowns must be an integer then it is classified in integer programming. A linear programming algorithm can solve such a problem if it can be proved that all restrictions for integer values are superficial, i.e., the solutions satisfy these restrictions anyway. In the general case, a specialized algorithm or an algorithm that finds approximate solutions is used, depending on the difficulty of the problem. Dynamic programming When a problem shows optimal substructures – meaning the optimal solution to a problem can be constructed from optimal solutions to subproblems – and overlapping subproblems, meaning the same subproblems are used to solve many different problem instances, a quicker approach called dynamic programming avoids recomputing solutions that have already been computed. For example, Floyd–Warshall algorithm, the shortest path to a goal from a vertex in a weighted graph can be found by using the shortest path to the goal from all adjacent vertices. Dynamic programming and memoization go together. The main difference between dynamic programming and divide and conquer is that subproblems are more or less independent in divide and conquer, whereas subproblems overlap in dynamic programming. The difference between dynamic programming and straightforward recursion is in caching or memoization of recursive calls. When subproblems are independent and there is no repetition, memoization does not help; hence dynamic programming is not a solution for all complex problems. By using memoization or maintaining a table of subproblems already solved, dynamic programming reduces the exponential nature of many problems to polynomial complexity. The greedy method A greedy algorithm is similar to a dynamic programming algorithm in that it works by examining substructures, in this case not of the problem but of a given solution. Such algorithms start with some solution, which may be given or have been constructed in some way, and improve it by making small modifications. For some problems they can find the optimal solution while for others they stop at local optima, that is, at solutions that cannot be improved by the algorithm but are not optimum. The most popular use of greedy algorithms is for finding the minimal spanning tree where finding the optimal solution is possible with this method. Huffman Tree, Kruskal, Prim, Sollin are greedy algorithms that can solve this optimization problem. The heuristic method In optimization problems, heuristic algorithms can be used to find a solution close to the optimal solution in cases where finding the optimal solution is impractical. These algorithms work by getting closer and closer to the optimal solution as they progress. In principle, if run for an infinite amount of time, they will find the optimal solution. Their merit is that they can find a solution very close to the optimal solution in a relatively short time. Such algorithms include local search, tabu search, simulated annealing, and genetic algorithms. Some of them, like simulated annealing, are non-deterministic algorithms while others, like tabu search, are deterministic. When a bound on the error of the non-optimal solution is known, the algorithm is further categorized as an approximation algorithm. === By field of study === Every field of science has its own problems and needs efficient algorithms. Related problems in one field are often studied together. Some example classes are search algorithms, sorting algorithms, merge algorithms, numerical algorithms, graph algorithms, string algorithms, computational geometric algorithms, combinatorial algorithms, medical algorithms, machine learning, cryptography, data compression algorithms and parsing techniques. Fields tend to overlap with each other, and algorithm advances in one field may improve those of other, sometimes completely unrelated, fields. For example, dynamic programming was invented for optimization of resource consumption in industry, but is now used in solving a broad range of problems in many fields. === By complexity === Algorithms can be classified by the amount of time they need to complete compared to their input size: Constant time: if the time needed by the algorithm is the same, regardless of the input size. E.g. an access to an array element. Linear time: if the time is proportional to the input size. E.g. the traverse of a list. Logarithmic time: if the time is a logarithmic function of the input size. E.g. binary search algorithm. Polynomial time: if the time is a power of the input size. E.g. the bubble sort algorithm has quadratic time complexity. Exponential time: if the time is an exponential function of the input size. E.g. Brute-force search.Some problems may have multiple algorithms of differing complexity, while other problems might have no algorithms or no known efficient algorithms. There are also mappings from some problems to other problems. Owing to this, it was found to be more suitable to classify the problems themselves instead of the algorithms into equivalence classes based on the complexity of the best possible algorithms for them. == Continuous algorithms == The adjective "continuous" when applied to the word "algorithm" can mean: An algorithm operating on data that represents continuous quantities, even though this data is represented by discrete approximations—such algorithms are studied in numerical analysis; or An algorithm in the form of a differential equation that operates continuously on the data, running on an analog computer. == Legal issues == Algorithms, by themselves, are not usually patentable. In the United States, a claim consisting solely of simple manipulations of abstract concepts, numbers, or signals does not constitute "processes" (USPTO 2006), and hence algorithms are not patentable (as in Gottschalk v. Benson). However, practical applications of algorithms are sometimes patentable. For example, in Diamond v. Diehr, the application of a simple feedback algorithm to aid in the curing of synthetic rubber was deemed patentable. The patenting of software is highly controversial, and there are highly criticized patents involving algorithms, especially data compression algorithms, such as Unisys' LZW patent. Additionally, some cryptographic algorithms have export restrictions (see export of cryptography). Researcher, Andrew Tutt, argues that algorithms should be overseen by a specialist regulatory agency, similar to FDA. His academic work emphasizes that the rise of increasingly complex algorithms calls for the need to think about the effects of algorithms today. Due to the nature and complexity of algorithms, it will prove to be difficult to hold algorithms accountable under criminal law. Tutt recognizes that while some algorithms will be beneficial to help meet technological demand, others should not be used or sold if they fail to meet safety requirements. Thus, for Tutt, algorithms will require "closer forms of federal uniformity, expert judgment, political independence, and pre-market review to prevent the introduction of unacceptably dangerous algorithms into the market". The issue of algorithmic accountability (the responsibility of algorithm designers to provide evidence of potential or realised harms) is of particular relevance in the field of dynamic and non-linearly programmed systems, e.g. artificial neural networks, deep learning, and genetic algorithms (see Explainable AI). == History: Development of the notion of "algorithm" == === Ancient Near East === Algorithms were used in ancient Greece. Two examples are the Sieve of Eratosthenes, which was described in Introduction to Arithmetic by Nicomachus, and the Euclidean algorithm, which was first described in Euclid's Elements (c. 300 BC). Babylonian clay tablets describe and employ algorithmic procedures to compute the time and place of significant astronomical events. === Discrete and distinguishable symbols === Tally-marks: To keep track of their flocks, their sacks of grain and their money the ancients used tallying: accumulating stones or marks scratched on sticks, or making discrete symbols in clay. Through the Babylonian and Egyptian use of marks and symbols, eventually Roman numerals and the abacus evolved (Dilson, p. 16–41). Tally marks appear prominently in unary numeral system arithmetic used in Turing machine and Post–Turing machine computations. === Manipulation of symbols as "place holders" for numbers: algebra === The work of the ancient Greek geometers (Euclidean algorithm), the Indian mathematician Brahmagupta, and the Persian mathematician Al-Khwarizmi (from whose name the terms "algorism" and "algorithm" are derived), and Western European mathematicians culminated in Leibniz's notion of the calculus ratiocinator (ca 1680): A good century and a half ahead of his time, Leibniz proposed an algebra of logic, an algebra that would specify the rules for manipulating logical concepts in the manner that ordinary algebra specifies the rules for manipulating numbers. === Mechanical contrivances with discrete states === The clock: Bolter credits the invention of the weight-driven clock as "The key invention [of Europe in the Middle Ages]", in particular the verge escapement that provides us with the tick and tock of a mechanical clock. "The accurate automatic machine" led immediately to "mechanical automata" beginning in the 13th century and finally to "computational machines"—the difference engine and analytical engines of Charles Babbage and Countess Ada Lovelace, mid-19th century. Lovelace is credited with the first creation of an algorithm intended for processing on a computer – Babbage's analytical engine, the first device considered a real Turing-complete computer instead of just a calculator – and is sometimes called "history's first programmer" as a result, though a full implementation of Babbage's second device would not be realized until decades after her lifetime. Logical machines 1870—Stanley Jevons' "logical abacus" and "logical machine": The technical problem was to reduce Boolean equations when presented in a form similar to what are now known as Karnaugh maps. Jevons (1880) describes first a simple "abacus" of "slips of wood furnished with pins, contrived so that any part or class of the [logical] combinations can be picked out mechanically . . . More recently however I have reduced the system to a completely mechanical form, and have thus embodied the whole of the indirect process of inference in what may be called a Logical Machine" His machine came equipped with "certain moveable wooden rods" and "at the foot are 21 keys like those of a piano [etc] . . .". With this machine he could analyze a "syllogism or any other simple logical argument".This machine he displayed in 1870 before the Fellows of the Royal Society. Another logician John Venn, however, in his 1881 Symbolic Logic, turned a jaundiced eye to this effort: "I have no high estimate myself of the interest or importance of what are sometimes called logical machines ... it does not seem to me that any contrivances at present known or likely to be discovered really deserve the name of logical machines"; see more at Algorithm characterizations. But not to be outdone he too presented "a plan somewhat analogous, I apprehend, to Prof. Jevon's abacus ... [And] [a]gain, corresponding to Prof. Jevons's logical machine, the following contrivance may be described. I prefer to call it merely a logical-diagram machine ... but I suppose that it could do very completely all that can be rationally expected of any logical machine".Jacquard loom, Hollerith punch cards, telegraphy and telephony—the electromechanical relay: Bell and Newell (1971) indicate that the Jacquard loom (1801), precursor to Hollerith cards (punch cards, 1887), and "telephone switching technologies" were the roots of a tree leading to the development of the first computers. By the mid-19th century the telegraph, the precursor of the telephone, was in use throughout the world, its discrete and distinguishable encoding of letters as "dots and dashes" a common sound. By the late 19th century the ticker tape (ca 1870s) was in use, as was the use of Hollerith cards in the 1890 U.S. census. Then came the teleprinter (ca. 1910) with its punched-paper use of Baudot code on tape. Telephone-switching networks of electromechanical relays (invented 1835) was behind the work of George Stibitz (1937), the inventor of the digital adding device. As he worked in Bell Laboratories, he observed the "burdensome' use of mechanical calculators with gears. "He went home one evening in 1937 intending to test his idea... When the tinkering was over, Stibitz had constructed a binary adding device".Davis (2000) observes the particular importance of the electromechanical relay (with its two "binary states" open and closed): It was only with the development, beginning in the 1930s, of electromechanical calculators using electrical relays, that machines were built having the scope Babbage had envisioned." === Mathematics during the 19th century up to the mid-20th century === Symbols and rules: In rapid succession the mathematics of George Boole (1847, 1854), Gottlob Frege (1879), and Giuseppe Peano (1888–1889) reduced arithmetic to a sequence of symbols manipulated by rules. Peano's The principles of arithmetic, presented by a new method (1888) was "the first attempt at an axiomatization of mathematics in a symbolic language".But Heijenoort gives Frege (1879) this kudos: Frege's is "perhaps the most important single work ever written in logic. ... in which we see a " 'formula language', that is a lingua characterica, a language written with special symbols, "for pure thought", that is, free from rhetorical embellishments ... constructed from specific symbols that are manipulated according to definite rules". The work of Frege was further simplified and amplified by Alfred North Whitehead and Bertrand Russell in their Principia Mathematica (1910–1913). The paradoxes: At the same time a number of disturbing paradoxes appeared in the literature, in particular the Burali-Forti paradox (1897), the Russell paradox (1902–03), and the Richard Paradox. The resultant considerations led to Kurt Gödel's paper (1931)—he specifically cites the paradox of the liar—that completely reduces rules of recursion to numbers. Effective calculability: In an effort to solve the Entscheidungsproblem defined precisely by Hilbert in 1928, mathematicians first set about to define what was meant by an "effective method" or "effective calculation" or "effective calculability" (i.e., a calculation that would succeed). In rapid succession the following appeared: Alonzo Church, Stephen Kleene and J. B. Rosser's λ-calculus a finely honed definition of "general recursion" from the work of Gödel acting on suggestions of Jacques Herbrand (cf. Gödel's Princeton lectures of 1934) and subsequent simplifications by Kleene. Church's proof that the Entscheidungsproblem was unsolvable, Emil Post's definition of effective calculability as a worker mindlessly following a list of instructions to move left or right through a sequence of rooms and while there either mark or erase a paper or observe the paper and make a yes-no decision about the next instruction. Alan Turing's proof of that the Entscheidungsproblem was unsolvable by use of his "a- [automatic-] machine"—in effect almost identical to Post's "formulation", J. Barkley Rosser's definition of "effective method" in terms of "a machine". S. C. Kleene's proposal of a precursor to "Church thesis" that he called "Thesis I", and a few years later Kleene's renaming his Thesis "Church's Thesis" and proposing "Turing's Thesis". === Emil Post (1936) and Alan Turing (1936–37, 1939) === Here is a remarkable coincidence of two men not knowing each other but describing a process of men-as-computers working on computations—and they yield virtually identical definitions. Emil Post (1936) described the actions of a "computer" (human being) as follows: "...two concepts are involved: that of a symbol space in which the work leading from problem to answer is to be carried out, and a fixed unalterable set of directions.His symbol space would be "a two way infinite sequence of spaces or boxes... The problem solver or worker is to move and work in this symbol space, being capable of being in, and operating in but one box at a time.... a box is to admit of but two possible conditions, i.e., being empty or unmarked, and having a single mark in it, say a vertical stroke."One box is to be singled out and called the starting point. ...a specific problem is to be given in symbolic form by a finite number of boxes [i.e., INPUT] being marked with a stroke. Likewise the answer [i.e., OUTPUT] is to be given in symbolic form by such a configuration of marked boxes...."A set of directions applicable to a general problem sets up a deterministic process when applied to each specific problem. This process terminates only when it comes to the direction of type (C ) [i.e., STOP]". See more at Post–Turing machine Alan Turing's work preceded that of Stibitz (1937); it is unknown whether Stibitz knew of the work of Turing. Turing's biographer believed that Turing's use of a typewriter-like model derived from a youthful interest: "Alan had dreamt of inventing typewriters as a boy; Mrs. Turing had a typewriter; and he could well have begun by asking himself what was meant by calling a typewriter 'mechanical'". Given the prevalence of Morse code and telegraphy, ticker tape machines, and teletypewriters we might conjecture that all were influences. Turing—his model of computation is now called a Turing machine—begins, as did Post, with an analysis of a human computer that he whittles down to a simple set of basic motions and "states of mind". But he continues a step further and creates a machine as a model of computation of numbers. "Computing is normally done by writing certain symbols on paper. We may suppose this paper is divided into squares like a child's arithmetic book...I assume then that the computation is carried out on one-dimensional paper, i.e., on a tape divided into squares. I shall also suppose that the number of symbols which may be printed is finite..."The behaviour of the computer at any moment is determined by the symbols which he is observing, and his "state of mind" at that moment. We may suppose that there is a bound B to the number of symbols or squares which the computer can observe at one moment. If he wishes to observe more, he must use successive observations. We will also suppose that the number of states of mind which need be taken into account is finite..."Let us imagine that the operations performed by the computer to be split up into 'simple operations' which are so elementary that it is not easy to imagine them further divided."Turing's reduction yields the following: "The simple operations must therefore include: "(a) Changes of the symbol on one of the observed squares "(b) Changes of one of the squares observed to another square within L squares of one of the previously observed squares."It may be that some of these change necessarily invoke a change of state of mind. The most general single operation must therefore be taken to be one of the following: "(A) A possible change (a) of symbol together with a possible change of state of mind. "(B) A possible change (b) of observed squares, together with a possible change of state of mind""We may now construct a machine to do the work of this computer."A few years later, Turing expanded his analysis (thesis, definition) with this forceful expression of it: "A function is said to be "effectively calculable" if its values can be found by some purely mechanical process. Though it is fairly easy to get an intuitive grasp of this idea, it is nevertheless desirable to have some more definite, mathematical expressible definition . . . [he discusses the history of the definition pretty much as presented above with respect to Gödel, Herbrand, Kleene, Church, Turing and Post] . . . We may take this statement literally, understanding by a purely mechanical process one which could be carried out by a machine. It is possible to give a mathematical description, in a certain normal form, of the structures of these machines. The development of these ideas leads to the author's definition of a computable function, and to an identification of computability † with effective calculability . . . . "† We shall use the expression "computable function" to mean a function calculable by a machine, and we let "effectively calculable" refer to the intuitive idea without particular identification with any one of these definitions". === J. B. Rosser (1939) and S. C. Kleene (1943) === J. Barkley Rosser defined an 'effective [mathematical] method' in the following manner (italicization added): "'Effective method' is used here in the rather special sense of a method each step of which is precisely determined and which is certain to produce the answer in a finite number of steps. With this special meaning, three different precise definitions have been given to date. [his footnote #5; see discussion immediately below]. The simplest of these to state (due to Post and Turing) says essentially that an effective method of solving certain sets of problems exists if one can build a machine which will then solve any problem of the set with no human intervention beyond inserting the question and (later) reading the answer. All three definitions are equivalent, so it doesn't matter which one is used. Moreover, the fact that all three are equivalent is a very strong argument for the correctness of any one." (Rosser 1939:225–6)Rosser's footnote No. 5 references the work of (1) Church and Kleene and their definition of λ-definability, in particular Church's use of it in his An Unsolvable Problem of Elementary Number Theory (1936); (2) Herbrand and Gödel and their use of recursion in particular Gödel's use in his famous paper On Formally Undecidable Propositions of Principia Mathematica and Related Systems I (1931); and (3) Post (1936) and Turing (1936–37) in their mechanism-models of computation. Stephen C. Kleene defined as his now-famous "Thesis I" known as the Church–Turing thesis. But he did this in the following context (boldface in original): "12. Algorithmic theories... In setting up a complete algorithmic theory, what we do is to describe a procedure, performable for each set of values of the independent variables, which procedure necessarily terminates and in such manner that from the outcome we can read a definite answer, "yes" or "no," to the question, "is the predicate value true?"" (Kleene 1943:273) === History after 1950 === A number of efforts have been directed toward further refinement of the definition of "algorithm", and activity is on-going because of issues surrounding, in particular, foundations of mathematics (especially the Church–Turing thesis) and philosophy of mind (especially arguments about artificial intelligence).

### Instruction: retrieve labels for this: An annual plant is a plant that completes its life cycle, from germination to the production of seeds, within one year, and then dies. Summer annuals germinate during spring or early summer and mature by autumn of the same year. Winter annuals germinate during the autumn and mature during the spring or summer of the following calendar year.One seed-to-seed life cycle for an annual can occur in as little as a month in some species, though most last several months. Oilseed rapa can go from seed-to-seed in about five weeks under a bank of fluorescent lamps. This style of growing is often used in classrooms for education. Many desert annuals are therophytes, because their seed-to-seed life cycle is only weeks and they spend most of the year as seeds to survive dry conditions. == Cultivation == In cultivation, many food plants are, or are grown as, annuals, including virtually all domesticated grains. Some perennials and biennials are grown in gardens as annuals for convenience, particularly if they are not considered cold hardy for the local climate. Carrot, celery and parsley are true biennials that are usually grown as annual crops for their edible roots, petioles and leaves, respectively. Tomato, sweet potato and bell pepper are tender perennials usually grown as annuals. Ornamental perennials commonly grown as annuals are impatiens, wax begonia, snapdragon, Pelargonium, coleus and petunia. Examples of true annuals include corn, wheat, rice, lettuce, peas, watermelon, beans, zinnia and marigold. == Summer == Summer annuals sprout, flower, produce seed, and die, during the warmer months of the year. The lawn weed crabgrass is a summer annual. == Winter == Winter annuals germinate in autumn or winter, live through the winter, then bloom in winter or spring. The plants grow and bloom during the cool season when most other plants are dormant or other annuals are in seed form waiting for warmer weather to germinate. Winter annuals die after flowering and setting seed. The seeds germinate in the autumn or winter when the soil temperature is cool. Winter annuals typically grow low to the ground, where they are usually sheltered from the coldest nights by snow cover, and make use of warm periods in winter for growth when the snow melts. Some common winter annuals include henbit, deadnettle, chickweed, and winter cress. Winter annuals are important ecologically, as they provide vegetative cover that prevents soil erosion during winter and early spring when no other cover exists and they provide fresh vegetation for animals and birds that feed on them. Although they are often considered to be weeds in gardens, this viewpoint is not always necessary, as most of them die when the soil temperature warms up again in early to late spring when other plants are still dormant and have not yet leafed out. Even though they do not compete directly with cultivated plants, sometimes winter annuals are considered a pest in commercial agriculture, because they can be hosts for insect pests or fungal diseases (ovary smut – Microbotryum sp) which attack crops being cultivated. The property that they prevent the soil from drying out can also be problematic for commercial agriculture. == Molecular genetics == In 2008, it was discovered that the inactivation of only two genes in one species of annual plant leads to the conversion into a perennial plant. Researchers deactivated the SOC1 and FUL genes in Arabidopsis thaliana, which control flowering time. This switch established phenotypes common in perennial plants, such as wood formation. == See also == Biennial plant Perennial plant == References == == External links == ### Answer: <Annual plants>, <Garden plants>, <Horticulture and gardening>, <Plants>

### Instruction: retrieve labels for this: The anthophytes were thought to be a clade comprising plants bearing flower-like structures. The group contained the angiosperms - the extant flowering plants, such as roses and grasses - as well as the Gnetales and the extinct Bennettitales.Detailed morphological and molecular studies have shown that the group is not actually monophyletic, with proposed floral homologies of the gnetophytes and the angiosperms having evolved in parallel. This makes it easier to reconcile molecular clock data that suggests that the angiosperms diverged from the gymnosperms around 300 million years ago.Some more recent studies have used the word anthophyte to describe a group which includes the angiosperms and a variety of fossils (glossopterids, Pentoxylon, Bennettitales, and Caytonia), but not the Gnetales. == References == ### Answer: <Plants>

### Instruction: retrieve labels for this: Mouthwash, mouth rinse, oral rinse, or mouth bath is a liquid which is held in the mouth passively or swilled around the mouth by contraction of the perioral muscles and/or movement of the head, and may be gargled, where the head is tilted back and the liquid bubbled at the back of the mouth. Usually mouthwashes are antiseptic solutions intended to reduce the microbial load in the oral cavity, although other mouthwashes might be given for other reasons such as for their analgesic, anti-inflammatory or anti-fungal action. Additionally, some rinses act as saliva substitutes to neutralize acid and keep the mouth moist in xerostomia (dry mouth). Cosmetic mouthrinses temporarily control or reduce bad breath and leave the mouth with a pleasant taste.Rinsing with water or mouthwash after brushing with a fluoride toothpaste can reduce the availability of salivary fluoride. This can lower the anti-cavity re-mineralization and antibacterial effects of fluoride. Fluoridated mouthwash may mitigate this effect or in high concentrations increase available fluoride. A group of experts discussing post brushing rinsing in 2012 found that there although was clear guidance given in many public health advice publications to "spit, avoid rinsing with water/excessive rinsing with water" they believed there was a limited evidence base for best practice. == Use == Common use involves rinsing the mouth with about 20-50 ml (2/3 fl oz) of mouthwash. The wash is typically swished or gargled for about half a minute and then spat out. Most companies suggest not drinking water immediately after using mouthwash. In some brands, the expectorate is stained, so that one can see the bacteria and debris. Mouthwash should not be used immediately after brushing the teeth so as not to wash away the beneficial fluoride residue left from the toothpaste. Similarly, the mouth should not be rinsed out with water after brushing. Patients were told to "spit don't rinse" after toothbrushing as part of a National Health Service campaign in the UK.Gargling is where the head is tilted back, allowing the mouthwash to sit in the back of the mouth while exhaling, causing the liquid to bubble. Gargling is practiced in Japan for perceived prevention of viral infection. One commonly used way is with infusions or tea. In some cultures, gargling is usually done in private, typically in a bathroom at a sink so the liquid can be rinsed away. == Benefits and side effects == The most common use of mouthwash is commercial antiseptics, which are used at home as part of an oral hygiene routine. Examples of commercial mouthwashes companies include Cēpacol, Colgate, Corsodyl, Dentyl pH, Listerine, Odol, Oral-B, Sarakan, Scope, Tantum verde, and Biotene. Mouthwashes combine ingredients to treat a variety of oral conditions. Variations are common, and mouthwash has no standard formulation so its use and recommendation involves concerns about patient safety. Some manufacturers of mouthwash state that antiseptic and anti-plaque mouth rinse kill the bacterial plaque that causes cavities, gingivitis, and bad breath. It is, however, generally agreed that the use of mouthwash does not eliminate the need for both brushing and flossing. The American Dental Association asserts that regular brushing and proper flossing are enough in most cases, in addition to regular dental check-ups, although they approve many mouthwashes. For many patients, however, the mechanical methods could be tedious and time-consuming and additionally some local conditions may render them especially difficult. Chemotherapeutic agents, including mouthrinses, could have a key role as adjuncts to daily home care, preventing and controlling supragingival plaque, gingivitis and oral malodor.Minor and transient side effects of mouthwashes are very common, such as taste disturbance, tooth staining, sensation of a dry mouth, etc. Alcohol-containing mouthwashes may make dry mouth and halitosis worse since it dries out the mouth. Soreness, ulceration and redness may sometimes occur (e.g. aphthous stomatitis, allergic contact stomatitis) if the person is allergic or sensitive to mouthwash ingredients such as preservatives, coloring, flavors and fragrances. Such effects might be reduced or eliminated by diluting the mouthwash with water, using a different mouthwash (e.g. salt water), or foregoing mouthwash entirely. Prescription mouthwashes are used prior to and after oral surgery procedures such as tooth extraction or to treat the pain associated with mucositis caused by radiation therapy or chemotherapy. They are also prescribed for aphthous ulcers, other oral ulcers, and other mouth pain. Magic mouthwashes are prescription mouthwashes compounded in a pharmacy from a list of ingredients specified by a doctor. Despite a lack of evidence that prescription mouthwashes are more effective in decreasing the pain of oral lesions, many patients and prescribers continue to use them. There has been only one controlled study to evaluate the efficacy of magic mouthwash; it shows no difference in efficacy among the most common formulation and commercial mouthwashes such as chlorhexidine or a saline/baking soda solution. Current guidelines suggest that saline solution is just as effective as magic mouthwash in pain relief or shortening of healing time of oral mucositis from cancer therapies. == History == The first known references to mouth rinsing is in Ayurveda for treatment of gingivitis. Later, in the Greek and Roman periods, mouth rinsing following mechanical cleansing became common among the upper classes, and Hippocrates recommended a mixture of salt, alum, and vinegar. The Jewish Talmud, dating back about 1,800 years, suggests a cure for gum ailments containing "dough water" and olive oil.Before Europeans came to the Americas, Native North American and Mesoamerican cultures used mouthwashes, often made from plants such as Coptis trifolia. Indeed, Aztec dentistry was more advanced than European dentistry of the age. Peoples of the Americas used salt water mouthwashes for sore throats, and other mouthwashes for problems such as teething and mouth ulcers.Anton van Leeuwenhoek, the famous 17th century microscopist, discovered living organisms (living, because they were mobile) in deposits on the teeth (what we now call dental plaque). He also found organisms in water from the canal next to his home in Delft. He experimented with samples by adding vinegar or brandy and found that this resulted in the immediate immobilization or killing of the organisms suspended in water. Next he tried rinsing the mouth of himself and somebody else with a mouthwash containing vinegar or brandy and found that living organisms remained in the dental plaque. He concluded—correctly—that the mouthwash either did not reach, or was not present long enough, to kill the plaque organisms. In 1892, German Richard Seifert invented mouthwash product Odol, which was produced by company founder Karl August Lingner (1861–1916) in Dresden.That remained the state of affairs until the late 1960s when Harald Loe (at the time a professor at the Royal Dental College in Aarhus, Denmark) demonstrated that a chlorhexidine compound could prevent the build-up of dental plaque. The reason for chlorhexidine's effectiveness is that it strongly adheres to surfaces in the mouth and thus remains present in effective concentrations for many hours.Since then commercial interest in mouthwashes has been intense and several newer products claim effectiveness in reducing the build-up in dental plaque and the associated severity of gingivitis, in addition to fighting bad breath. Many of these solutions aim to control the Volatile Sulfur Compound (VSC)-creating anaerobic bacteria that live in the mouth and excrete substances that lead to bad breath and unpleasant mouth taste. For example, the number of mouthwash variants in the United States of America has grown from 15 (1970) to 66 (1998) to 113 (2012). == Research == Research in the field of microbiotas shows that only a limited set of microbes cause tooth decay, with most of the bacteria in the human mouth being harmless. Focused attention on cavity-causing bacteria such as Streptococcus mutans has led research into new mouthwash treatments that prevent these bacteria from initially growing. While current mouthwash treatments must be used with a degree of frequency to prevent this bacteria from regrowing, future treatments could provide a viable long term solution. == Ingredients == === Alcohol === Alcohol is added to mouthwash not to destroy bacteria but to act as a carrier agent for essential active ingredients such as menthol, eucalyptol and thymol which help to penetrate plaque. Sometimes a significant amount of alcohol (up to 27% vol) is added, as a carrier for the flavor, to provide "bite". Because of the alcohol content, it is possible to fail a breathalyzer test after rinsing although breath alcohol levels return to normal after 10 minutes. In addition, alcohol is a drying agent, which encourages bacterial activity in the mouth, releasing more malodorous volatile sulfur compounds. Therefore, alcohol-containing mouthwash may temporarily worsen halitosis in those who already have it, or indeed be the sole cause of halitosis in other individuals.It is hypothesized that alcohol mouthwashes acts as a carcinogen (cancer-inducing). Generally, there is no scientific consensus about this. One review stated: There is now sufficient evidence to accept the proposition that developing oral cancer is increased or contributed to by the use of alcohol-containing mouthwashes. Whilst many of these products may have been shown to be effective in penetrating oral microbial biofilms in vitro and reducing oral bacterial load, it would be wise to restrict their use to short-term therapeutic situations if needed. Perhaps the use of mouthwashes that do not contain alcohol may be equally effective. Further, mouthrinses should be prescribed by dentists, like any other medication. There may well be a reason for the use of alcohol-containing mouthrinses, but only for a particular situation and for a limited and controlled period of time. As such, patients should be provided with written instructions for mouthwash use, and mouthwash use should be restricted to adults for short durations and specific, clearly defined reasons. It is the opinion of the authors that, in light of the evidence currently available of the association of alcohol-containing mouthwashes with the development of oral cancer, it would be inadvisable for oral healthcare professionals to recommend the long-term use of alcohol-containing mouthwashes. The same researchers also state that the risk of acquiring oral cancer rises almost five times for users of alcohol-containing mouthwash who neither smoke nor drink (with a higher rate of increase for those who do). In addition, the authors highlight side effects from several mainstream mouthwashes that included dental erosion and accidental poisoning of children. The review garnered media attention and conflicting opinions from other researchers. Yinka Ebo of Cancer Research UK disputed the findings, concluding that "there is still not enough evidence to suggest that using mouthwash that contains alcohol will increase the risk of mouth cancer". Studies conducted in 1985, 1995, 2003, and 2012 did not support an association between alcohol-containing mouth rinses and oral cancer. Andrew Penman, chief executive of The Cancer Council New South Wales, called for further research on the matter. In a March 2009 brief, the American Dental Association said "the available evidence does not support a connection between oral cancer and alcohol-containing mouthrinse". Many newer brands of mouthwash are alcohol free, not just in response to consumer concerns about oral cancer, but also to cater for religious groups who abstain from alcohol consumption. === Antibiotics === === Benzalkonium chloride === === Benzydamine/Difflam (analgesics) === In painful oral conditions such as aphthous stomatitis, analgesic mouthrinses (e.g. benzydamine mouthwash, or "Difflam") are sometimes used to ease pain, commonly used before meals to reduce discomfort while eating. === Benzoic acid === Acts as a buffer === Betadine === === Betamethasone === Betamethasone is sometimes used as an anti-inflammatory, corticosteroid mouthwash. It may be used for severe inflammatory conditions of the oral mucosa such as the severe forms of aphthous stomatitis. === Calcium === === Cetylpyridinium chloride (antiseptic, antimalodor) === Cetylpyridinium chloride containing mouthwash (e.g. 0.05%) is used in some specialized mouthwashes for halitosis. Cetylpyridinium chloride mouthwash has less anti-plaque effect than chlorhexidine and may cause staining of teeth, or sometimes an oral burning sensation or ulceration. === Chlorhexidine digluconate and Hexetidine (antiseptic) === Chlorhexidine digluconate is a chemical antiseptic and is used in a 0.12-0.2% solution as a mouthwash. However, there is no evidence to support that higher concentrations are more effective in controlling dental plaque and gingivitis. It has anti-plaque action, but also some anti-fungal action. It is especially effective against Gram-negative rods. The proportion of Gram-negative rods increase as gingivitis develops so it is also used to reduce gingivitis. It is sometimes used as an adjunct to prevent dental caries and to treat gingivitis periodontal disease, although it does not penetrate into periodontal pockets well. Chlorhexidine mouthwash alone is unable to prevent plaque, so it is not a substitute for regular toothbrushing and flossing. Instead, chlorhexidine is more effective used as an adjunctive treatment with tooth brushing and flossing. In the short term, if toothbrushing is impossible due to pain, as may occur in primary herpetic gingivostomatitis, chlorhexidine is used as temporary substitute for other oral hygiene measures. It is not suited for use in acute necrotizing ulcerative gingivitis, however. Rinsing with chlorhexidine mouthwash before a tooth extraction reduces the risk of dry socket, a painful condition where the blood clot is lost from an extraction socket and bone is exposed to the oral cavity. Other uses of chlorhexidine mouthwash include prevention of oral candidiasis in immunocompromised persons, treatment of denture-related stomatitis, mucosal ulceration/erosions and oral mucosal lesions, general burning sensation and many other uses.Chlorhexidine has good substantivity (the ability of a mouthwash to bind to hard and soft tissues in the mouth). However, chlorhexidine binds to tannins, meaning that prolonged use in persons who consume coffee, tea or red wine is associated with extrinsic staining (i.e. removable staining) of teeth. Chlorhexidine mouthwash can also cause taste disturbance and/or alteration. Chlorhexidine is rarely associated with other issues like overgrowth of enterobacteria in persons with leukemia, desquamation and irritation of oral mucosa, salivary gland pain and swelling, and hypersensitivity reactions including anaphylaxis. A randomized clinical trial conducted in Rabat university in Morocco found better results in plaque inhibition when chlorohexidine with alcohol base 0.12% was used , when compared to an alcohol free 0.1% chlorhexidine mouthrinse.Hexetidine also has anti-plaque, analgesic, astringent and anti-malodor properties but is considered as an inferior alternative to Chlorhexidine. === Diphenhydramine === antihistamine === Domiphen bromide === === Edible oils === In traditional Ayurvedic medicine, the use of oil mouthwashes is called "Kavala" ("oil swishing") or "Gandusha", and this practice has more recently been re-marketed by the complimentary and alternative medicine industry as "oil pulling". Its promoters claim it works by "pulling out" "toxins", which are known as ama in Ayurvedic medicine, and thereby reducing inflammation. Ayurvedic literature suggests oil pulling is capable of improving oral and systemic health, including a benefit in conditions such as headaches, migraines, diabetes mellitus, asthma, and acne, as well as whitening teeth.Oil pulling has received little study and there is little evidence to support claims made by the technique's advocates. When compared with chlorhexidine in one small study, it was found to be less effective at reducing oral bacterial load, otherwise the health claims of oil pulling have failed scientific verification or have not been investigated. There is a report of lipid pneumonia caused by accidental inhalation of the oil during oil pulling.The mouth is rinsed with approximately one tablespoon of oil for 10–20 minutes then spat out. Sesame oil, coconut oil and ghee are traditionally used, but newer oils such as sunflower oil are also used. === Essential oils and phenols === Phenolic compounds include essential oil constituents that have some antibacterial properties, like phenol, thymol, eugenol, eucalyptol or menthol.Essential oils are oils which have been extracted from plants. Mouthwashes based on essential oils could be more effective than traditional mouthcare - for anti-gingival treatments. They have been found effective in reducing halitosis, and are being used in several commercial mouthwashes. === Fluoride (anticavity) === Anti-cavity mouth rinses use fluoride to protect against tooth decay. Most people using fluoridated toothpastes do not require fluoride-containing mouth rinses, rather fluoride mouthwashes are sometimes used in individuals who are at high risk of dental decay, due to dental caries or people with xerostomia. === Flavoring agents and Xylitol === Flavoring agents include sweeteners such as sorbitol, sucralose, sodium saccharin, and xylitol, which stimulate salivary function due to their sweetness and taste and helps restore the mouth to a neutral level of acidity.Xylitol rinses double as a bacterial inhibitor and have been used as substitute for Alcohol to avoid dryness of mouth associated with Alcohol. === Glucocorticoids (anti-inflammatory) === === Hydrogen peroxide === Hydrogen peroxide can be used as an oxidizing mouthwash (e.g. Peroxyl, 1.5%). It kills anaerobic bacteria, and also has a mechanical cleansing action when it froths as it comes into contact with debris in mouth. It is often used in the short term to treat acute necrotising ulcerative gingivitis. Side effects with prolonged use might occur, including hypertrophy of the lingual papillae. === Lactoperoxidase (saliva substitute) === Enzymes and proteins such as Lactoperoxidase, Lysozyme, Lactoferrin have been used in mouthrinses (e.g. Biotene) to reduce oral bacteria and hence the acid produced by bacteria. === Lidocaine/xylocaine === Oral lidocaine is useful for the treatment of mucositis symptoms( mucous membranes inflammation) that is induced by radiation or chemotherapy. There is evidence that lidocaine anesthetic mouthwash has the potential to be systemically absorbed when it was tested in patients with oral mucositis who underwent a bone marrow transplant.local anesthetic === Maalox === Antacid === Methyl salicylate === Multiple functions - Anti-septic, Anti-inflammatory, Analgesic, Flavoring and Fragrance Methylsalicylates have some anti-plaque action but less substantivity than chlorhexidine. They do not stain teeth. === Nystatin === Nystatin suspension is an antifungal ingredient used for the treatment of oral candidiasis. === Persica or alum === === Potassium oxalate === A randomized clinical trial found promising results in controlling and reducing dentine hypersensitivity when potassium oxalate mouthrinse was used in conjugation with toothbrushing. === Povidone/iodine === A 2005 study found that gargling three times a day with simple water or with a Povidone-iodine solution was effective in preventing upper respiratory infection and decreasing the severity of symptoms if contracted. A later study found that the same procedure did not prevent influenza-like illnesses. Other sources attribute the benefit to a simple placebo effect. === Sanguinarine === Sanguinarine-containing mouthwashes are marketed as anti-plaque and anti-malodor. It is a toxic alkaloid herbal extract, obtained from plants such as Sanguinaria canadensis (Bloodroot), Argemone mexicana (Mexican Prickly Poppy) and others. However, its use is strongly associated with development of leukoplakia (a white patch in the mouth), usually in the buccal sulcus. This type of leukoplakia has been termed "sanguinaria-associated keratosis" and more than 80% of people with leukoplakia in the vestibule of the mouth have used this substance. Upon stopping contact with the causative substance, the lesions may persist for years. Although this type of leukoplakia may show dysplasia, the potential for malignant transformation is unknown. Ironically, elements within the complimentary and alternative medicine industry promote the use of sanguinaria as a therapy for cancer. === Sodium benzoate or methylparaben (preservatives) === === Sodium bicarbonate (baking soda) === Sodium bicarbonate is sometimes combined with salt to make a simple homemade mouthwash, indicated for any of the reasons that a salt water mouthwash might be used. Pre-mixed mouthwashes of 1% sodium bicarbonate and 1.5% sodium chloride in aqueous solution are marketed, although pharmacists will easily be able to produce such a formulation from the base ingredients when required. Sodium bicarbonate mouthwash is sometimes used to remove viscous saliva and to aid visualization of the oral tissues during examination of the mouth. === Sodium chloride (salt) === Salt water mouth wash is made by dissolving 0.5–1 teaspoon of table salt into a cup of water, which is as hot as possible without causing discomfort in the mouth. Saline has a mechanical cleansing action and an antiseptic action as it is a hypertonic solution in relation to bacteria, which undergo lysis. The heat of the solution produces a therapeutic increase in blood flow (hyperemia) to the surgical site, promoting healing. Hot salt water mouthwashes also encourage the draining of pus from dental abscesses. Conversely, if heat is applied on the side of the face (e.g., hot water bottle) rather than inside the mouth, it may cause a dental abscess to drain extra-orally, which is later associated with an area of fibrosis on the face (see cutaneous sinus of dental origin). Gargling with salt water is said to reduce the symptoms of a sore throat.Hot salt water mouth baths (or hot salt water mouth washes, sometimes abbreviated to "HSWMW") are also routinely used after oral surgery, to keep food debris out of healing wounds and to prevent infection. Some oral surgeons consider salt water mouthwashes the mainstay of wound cleanliness after surgery. In dental extractions, hot salt water mouthbaths should start about 24 hours after a dental extraction. The term mouth bath implies that the liquid is passively held in the mouth rather than vigorously swilled around, which could dislodge a blood clot. Once the blood clot has stabilized, the mouth wash can be used more vigorously. These mouthwashes tend to be advised about 6 times per day, especially after meals to remove food from the socket. === Sodium lauryl sulfate (foaming agent) === Sodium lauryl sulfate (SLS) is user as a foaming agent in many oral hygiene products including many mouthwashes. Some may suggest that it is probably advisable to use mouthwash at least an hour after brushing with toothpaste when the toothpaste contains SLS, since the anionic compounds in the SLS toothpaste can deactivate cationic agents present in the mouthrinse. However, many of the popular mouthwashes also contain SLS as an ingredient (e.g., Listerine Total Care). === Sucralfate === Sucralfate is a mucosal coating agent, composed of an aluminum salt of sulfated sucrose. It is not recommended for use in the prevention of oral mucositis in head and neck cancer patients receiving radiotherapy or chemoradiation due to a lack of efficacy found in a well-designed, randomized controlled trial. === Tetracycline (antibiotic) === Tetracycline is an antibiotic which may sometimes be used as a mouthwash in adults (it causes red staining of teeth in children). It is sometimes use for herpetiforme ulceration (an uncommon type of aphthous stomatitis), but prolonged use may lead to oral candidiasis as the fungal population of the mouth overgrows in the absence of enough competing bacteria. Similarly, Minocycline mouthwashes of 0.5% concentrations can relieve symptoms of recurrent aphthous stomatitis. Erythromycin is similar. === Tranexamic acid === 4.8% tranexamic acid solution is sometimes used as an antifibrinolytic mouthwash to prevent bleeding during and after oral surgery in persons with coagulopathies (clotting disorders) or who are taking anticoagulants (blood thinners such as warfarin). == Triclosan == Triclosan is a non-ionic chlorinate bisphenol antiseptic found in some mouthwashes. When used in mouthwash (e.g. 0.03%), there is moderate substantivity, broad spectrum anti-bacterial action, some anti-fungal action and significant anti-plaque effect, especially when combined with copolymer or zinc citrate. Triclosan does not cause staining of the teeth. The safety of triclosan has been questioned. === Zinc === Astringents like zinc chloride provide a pleasant-tasting sensation and shrink tissues. Zinc when used in combination with other anti-septic agents can limit the build-up of tartar == References == == External links == Article on Bad-Breath Prevention Products – from MSNBC Mayo Clinic Q&A on Magic Mouthwash for chemotherapy sores Gargle at the Centre for Cancer Education, University of Newcastle upon Tyne ### Answer: <Dentifrices>, <Dosage forms>, <Drug delivery devices>, <Oral hygiene>

### Instruction: retrieve labels for this: Alexander III of Macedon (20/21 July 356 BC – 10/11 June 323 BC), commonly known as Alexander the Great (Ancient Greek: Ἀλέξανδρος ὁ Μέγας, translit. Aléxandros ho Mégas, Koine Greek: [a.lék.san.dros ho mé.gas]), was a king (basileus) of the ancient Greek kingdom of Macedon and a member of the Argead dynasty. He was born in Pella in 356 BC and succeeded his father Philip II to the throne at the age of twenty. He spent most of his ruling years on an unprecedented military campaign through Asia and northeast Africa, and he created one of the largest empires of the ancient world by the age of thirty, stretching from Greece to northwestern India. He was undefeated in battle and is widely considered one of history's most successful military commanders.During his youth, Alexander was tutored by Aristotle until age 16. After Philip's assassination in 336 BC, he succeeded his father to the throne and inherited a strong kingdom and an experienced army. Alexander was awarded the generalship of Greece and used this authority to launch his father's pan-Hellenic project to lead the Greeks in the conquest of Persia. In 334 BC, he invaded the Achaemenid Empire (Persian Empire) and began a series of campaigns that lasted ten years. Following the conquest of Anatolia, Alexander broke the power of Persia in a series of decisive battles, most notably the battles of Issus and Gaugamela. He subsequently overthrew Persian King Darius III and conquered the Achaemenid Empire in its entirety. At that point, his empire stretched from the Adriatic Sea to the Indus River. He endeavored to reach the "ends of the world and the Great Outer Sea" and invaded India in 326 BC, winning an important victory over the Pauravas at the Battle of the Hydaspes. He eventually turned back at the demand of his homesick troops. Alexander died in Babylon in 323 BC, the city that he planned to establish as his capital, without executing a series of planned campaigns that would have begun with an invasion of Arabia. In the years following his death, a series of civil wars tore his empire apart, resulting in the establishment of several states ruled by the Diadochi, Alexander's surviving generals and heirs. Alexander's legacy includes the cultural diffusion and syncretism which his conquests engendered, such as Greco-Buddhism. He founded some twenty cities that bore his name, most notably Alexandria in Egypt. Alexander's settlement of Greek colonists and the resulting spread of Greek culture in the east resulted in a new Hellenistic civilization, aspects of which were still evident in the traditions of the Byzantine Empire in the mid-15th century AD and the presence of Greek speakers in central and far eastern Anatolia until the 1920s. Alexander became legendary as a classical hero in the mold of Achilles, and he features prominently in the history and mythic traditions of both Greek and non-Greek cultures. He became the measure against which military leaders compared themselves, and military academies throughout the world still teach his tactics. He is often ranked among the most influential people in history. == Early life == === Lineage and childhood === Alexander was born on the sixth day of the ancient Greek month of Hekatombaion, which probably corresponds to 20 July 356 BC, although the exact date is disputed, in Pella, the capital of the Kingdom of Macedon. He was the son of the king of Macedon, Philip II, and his fourth wife, Olympias, the daughter of Neoptolemus I, king of Epirus. Although Philip had seven or eight wives, Olympias was his principal wife for some time, likely because she gave birth to Alexander. Several legends surround Alexander's birth and childhood. According to the ancient Greek biographer Plutarch, on the eve of the consummation of her marriage to Philip, Olympias dreamed that her womb was struck by a thunder bolt that caused a flame to spread "far and wide" before dying away. Sometime after the wedding, Philip is said to have seen himself, in a dream, securing his wife's womb with a seal engraved with a lion's image. Plutarch offered a variety of interpretations of these dreams: that Olympias was pregnant before her marriage, indicated by the sealing of her womb; or that Alexander's father was Zeus. Ancient commentators were divided about whether the ambitious Olympias promulgated the story of Alexander's divine parentage, variously claiming that she had told Alexander, or that she dismissed the suggestion as impious.On the day Alexander was born, Philip was preparing a siege on the city of Potidea on the peninsula of Chalcidice. That same day, Philip received news that his general Parmenion had defeated the combined Illyrian and Paeonian armies, and that his horses had won at the Olympic Games. It was also said that on this day, the Temple of Artemis in Ephesus, one of the Seven Wonders of the World, burnt down. This led Hegesias of Magnesia to say that it had burnt down because Artemis was away, attending the birth of Alexander. Such legends may have emerged when Alexander was king, and possibly at his own instigation, to show that he was superhuman and destined for greatness from conception.In his early years, Alexander was raised by a nurse, Lanike, sister of Alexander's future general Cleitus the Black. Later in his childhood, Alexander was tutored by the strict Leonidas, a relative of his mother, and by Lysimachus of Acarnania. Alexander was raised in the manner of noble Macedonian youths, learning to read, play the lyre, ride, fight, and hunt.When Alexander was ten years old, a trader from Thessaly brought Philip a horse, which he offered to sell for thirteen talents. The horse refused to be mounted, and Philip ordered it away. Alexander however, detecting the horse's fear of its own shadow, asked to tame the horse, which he eventually managed. Plutarch stated that Philip, overjoyed at this display of courage and ambition, kissed his son tearfully, declaring: "My boy, you must find a kingdom big enough for your ambitions. Macedon is too small for you", and bought the horse for him. Alexander named it Bucephalas, meaning "ox-head". Bucephalas carried Alexander as far as India. When the animal died (because of old age, according to Plutarch, at age thirty), Alexander named a city after him, Bucephala. === Education === When Alexander was 13, Philip began to search for a tutor, and considered such academics as Isocrates and Speusippus, the latter offering to resign from his stewardship of the Academy to take up the post. In the end, Philip chose Aristotle and provided the Temple of the Nymphs at Mieza as a classroom. In return for teaching Alexander, Philip agreed to rebuild Aristotle's hometown of Stageira, which Philip had razed, and to repopulate it by buying and freeing the ex-citizens who were slaves, or pardoning those who were in exile.Mieza was like a boarding school for Alexander and the children of Macedonian nobles, such as Ptolemy, Hephaistion, and Cassander. Many of these students would become his friends and future generals, and are often known as the 'Companions'. Aristotle taught Alexander and his companions about medicine, philosophy, morals, religion, logic, and art. Under Aristotle's tutelage, Alexander developed a passion for the works of Homer, and in particular the Iliad; Aristotle gave him an annotated copy, which Alexander later carried on his campaigns. == Philip's heir == === Regency and ascent of Macedon === At age 16, Alexander's education under Aristotle ended. Philip waged war against Byzantion, leaving Alexander in charge as regent and heir apparent. During Philip's absence, the Thracian Maedi revolted against Macedonia. Alexander responded quickly, driving them from their territory. He colonized it with Greeks, and founded a city named Alexandropolis.Upon Philip's return, he dispatched Alexander with a small force to subdue revolts in southern Thrace. Campaigning against the Greek city of Perinthus, Alexander is reported to have saved his father's life. Meanwhile, the city of Amphissa began to work lands that were sacred to Apollo near Delphi, a sacrilege that gave Philip the opportunity to further intervene in Greek affairs. Still occupied in Thrace, he ordered Alexander to muster an army for a campaign in southern Greece. Concerned that other Greek states might intervene, Alexander made it look as though he was preparing to attack Illyria instead. During this turmoil, the Illyrians invaded Macedonia, only to be repelled by Alexander.Philip and his army joined his son in 338 BC, and they marched south through Thermopylae, taking it after stubborn resistance from its Theban garrison. They went on to occupy the city of Elatea, only a few days' march from both Athens and Thebes. The Athenians, led by Demosthenes, voted to seek alliance with Thebes against Macedonia. Both Athens and Philip sent embassies to win Thebes' favour, but Athens won the contest. Philip marched on Amphissa (ostensibly acting on the request of the Amphictyonic League), capturing the mercenaries sent there by Demosthenes and accepting the city's surrender. Philip then returned to Elatea, sending a final offer of peace to Athens and Thebes, who both rejected it. As Philip marched south, his opponents blocked him near Chaeronea, Boeotia. During the ensuing Battle of Chaeronea, Philip commanded the right wing and Alexander the left, accompanied by a group of Philip's trusted generals. According to the ancient sources, the two sides fought bitterly for some time. Philip deliberately commanded his troops to retreat, counting on the untested Athenian hoplites to follow, thus breaking their line. Alexander was the first to break the Theban lines, followed by Philip's generals. Having damaged the enemy's cohesion, Philip ordered his troops to press forward and quickly routed them. With the Athenians lost, the Thebans were surrounded. Left to fight alone, they were defeated.After the victory at Chaeronea, Philip and Alexander marched unopposed into the Peloponnese, welcomed by all cities; however, when they reached Sparta, they were refused, but did not resort to war. At Corinth, Philip established a "Hellenic Alliance" (modelled on the old anti-Persian alliance of the Greco-Persian Wars), which included most Greek city-states except Sparta. Philip was then named Hegemon (often translated as "Supreme Commander") of this league (known by modern scholars as the League of Corinth), and announced his plans to attack the Persian Empire. === Exile and return === When Philip returned to Pella, he fell in love with and married Cleopatra Eurydice, the niece of his general Attalus. The marriage made Alexander's position as heir less secure, since any son of Cleopatra Eurydice would be a fully Macedonian heir, while Alexander was only half-Macedonian. During the wedding banquet, a drunken Attalus publicly prayed to the gods that the union would produce a legitimate heir. At the wedding of Cleopatra, whom Philip fell in love with and married, she being much too young for him, her uncle Attalus in his drink desired the Macedonians would implore the gods to give them a lawful successor to the kingdom by his niece. This so irritated Alexander, that throwing one of the cups at his head, "You villain," said he, "what, am I then a bastard?" Then Philip, taking Attalus's part, rose up and would have run his son through; but by good fortune for them both, either his over-hasty rage, or the wine he had drunk, made his foot slip, so that he fell down on the floor. At which Alexander reproachfully insulted over him: "See there," said he, "the man who makes preparations to pass out of Europe into Asia, overturned in passing from one seat to another." Alexander fled Macedon with his mother, dropping her off with her brother, King Alexander I of Epirus in Dodona, capital of the Molossians. He continued to Illyria, where he sought refuge with the Illyrian king and was treated as a guest, despite having defeated them in battle a few years before. However, it appears Philip never intended to disown his politically and militarily trained son. Accordingly, Alexander returned to Macedon after six months due to the efforts of a family friend, Demaratus, who mediated between the two parties.In the following year, the Persian satrap (governor) of Caria, Pixodarus, offered his eldest daughter to Alexander's half-brother, Philip Arrhidaeus. Olympias and several of Alexander's friends suggested this showed Philip intended to make Arrhidaeus his heir. Alexander reacted by sending an actor, Thessalus of Corinth, to tell Pixodarus that he should not offer his daughter's hand to an illegitimate son, but instead to Alexander. When Philip heard of this, he stopped the negotiations and scolded Alexander for wishing to marry the daughter of a Carian, explaining that he wanted a better bride for him. Philip exiled four of Alexander's friends, Harpalus, Nearchus, Ptolemy and Erigyius, and had the Corinthians bring Thessalus to him in chains. === Gallery of campaigns === == King of Macedon == === Accession === In summer 336 BC, while at Aegae attending the wedding of his daughter Cleopatra to Olympias's brother, Alexander I of Epirus, Philip was assassinated by the captain of his bodyguards, Pausanias. As Pausanias tried to escape, he tripped over a vine and was killed by his pursuers, including two of Alexander's companions, Perdiccas and Leonnatus. Alexander was proclaimed king on the spot by the nobles and army at the age of 20. === Consolidation of power === Alexander began his reign by eliminating potential rivals to the throne. He had his cousin, the former Amyntas IV, executed. He also had two Macedonian princes from the region of Lyncestis killed, but spared a third, Alexander Lyncestes. Olympias had Cleopatra Eurydice and Europa, her daughter by Philip, burned alive. When Alexander learned about this, he was furious. Alexander also ordered the murder of Attalus, who was in command of the advance guard of the army in Asia Minor and Cleopatra's uncle.Attalus was at that time corresponding with Demosthenes, regarding the possibility of defecting to Athens. Attalus also had severely insulted Alexander, and following Cleopatra's murder, Alexander may have considered him too dangerous to leave alive. Alexander spared Arrhidaeus, who was by all accounts mentally disabled, possibly as a result of poisoning by Olympias.News of Philip's death roused many states into revolt, including Thebes, Athens, Thessaly, and the Thracian tribes north of Macedon. When news of the revolts reached Alexander, he responded quickly. Though advised to use diplomacy, Alexander mustered 3,000 Macedonian cavalry and rode south towards Thessaly. He found the Thessalian army occupying the pass between Mount Olympus and Mount Ossa, and ordered his men to ride over Mount Ossa. When the Thessalians awoke the next day, they found Alexander in their rear and promptly surrendered, adding their cavalry to Alexander's force. He then continued south towards the Peloponnese.Alexander stopped at Thermopylae, where he was recognized as the leader of the Amphictyonic League before heading south to Corinth. Athens sued for peace and Alexander pardoned the rebels. The famous encounter between Alexander and Diogenes the Cynic occurred during Alexander's stay in Corinth. When Alexander asked Diogenes what he could do for him, the philosopher disdainfully asked Alexander to stand a little to the side, as he was blocking the sunlight. This reply apparently delighted Alexander, who is reported to have said "But verily, if I were not Alexander, I would like to be Diogenes." At Corinth, Alexander took the title of Hegemon ("leader") and, like Philip, was appointed commander for the coming war against Persia. He also received news of a Thracian uprising. === Balkan campaign === Before crossing to Asia, Alexander wanted to safeguard his northern borders. In the spring of 335 BC, he advanced to suppress several revolts. Starting from Amphipolis, he travelled east into the country of the "Independent Thracians"; and at Mount Haemus, the Macedonian army attacked and defeated the Thracian forces manning the heights. The Macedonians marched into the country of the Triballi, and defeated their army near the Lyginus river (a tributary of the Danube). Alexander then marched for three days to the Danube, encountering the Getae tribe on the opposite shore. Crossing the river at night, he surprised them and forced their army to retreat after the first cavalry skirmish.News then reached Alexander that Cleitus, King of Illyria, and King Glaukias of the Taulantii were in open revolt against his authority. Marching west into Illyria, Alexander defeated each in turn, forcing the two rulers to flee with their troops. With these victories, he secured his northern frontier.While Alexander campaigned north, the Thebans and Athenians rebelled once again. Alexander immediately headed south. While the other cities again hesitated, Thebes decided to fight. The Theban resistance was ineffective, and Alexander razed the city and divided its territory between the other Boeotian cities. The end of Thebes cowed Athens, leaving all of Greece temporarily at peace. Alexander then set out on his Asian campaign, leaving Antipater as regent. == Conquest of the Persian Empire == === Asia Minor === Alexander's army crossed the Hellespont in 334 BC with approximately 48,100 soldiers, 6,100 cavalry and a fleet of 120 ships with crews numbering 38,000, drawn from Macedon and various Greek city-states, mercenaries, and feudally raised soldiers from Thrace, Paionia, and Illyria. He showed his intent to conquer the entirety of the Persian Empire by throwing a spear into Asian soil and saying he accepted Asia as a gift from the gods. This also showed Alexander's eagerness to fight, in contrast to his father's preference for diplomacy.After an initial victory against Persian forces at the Battle of the Granicus, Alexander accepted the surrender of the Persian provincial capital and treasury of Sardis; he then proceeded along the Ionian coast, granting autonomy and democracy to the cities. Miletus, held by Achaemenid forces, required a delicate siege operation, with Persian naval forces nearby. Further south, at Halicarnassus, in Caria, Alexander successfully waged his first large-scale siege, eventually forcing his opponents, the mercenary captain Memnon of Rhodes and the Persian satrap of Caria, Orontobates, to withdraw by sea. Alexander left the government of Caria to a member of the Hecatomnid dynasty, Ada, who adopted Alexander.From Halicarnassus, Alexander proceeded into mountainous Lycia and the Pamphylian plain, asserting control over all coastal cities to deny the Persians naval bases. From Pamphylia onwards the coast held no major ports and Alexander moved inland. At Termessos, Alexander humbled but did not storm the Pisidian city. At the ancient Phrygian capital of Gordium, Alexander "undid" the hitherto unsolvable Gordian Knot, a feat said to await the future "king of Asia". According to the story, Alexander proclaimed that it did not matter how the knot was undone and hacked it apart with his sword. === The Levant and Syria === In spring 333 BC, Alexander crossed the Taurus into Cilicia. After a long pause due to an illness, he marched on towards Syria. Though outmanoeuvered by Darius' significantly larger army, he marched back to Cilicia, where he defeated Darius at Issus. Darius fled the battle, causing his army to collapse, and left behind his wife, his two daughters, his mother Sisygambis, and a fabulous treasure. He offered a peace treaty that included the lands he had already lost, and a ransom of 10,000 talents for his family. Alexander replied that since he was now king of Asia, it was he alone who decided territorial divisions. Alexander proceeded to take possession of Syria, and most of the coast of the Levant. In the following year, 332 BC, he was forced to attack Tyre, which he captured after a long and difficult siege. The men of military age were massacred and the women and children sold into slavery. === Egypt === When Alexander destroyed Tyre, most of the towns on the route to Egypt quickly capitulated. However, Alexander met with resistance at Gaza. The stronghold was heavily fortified and built on a hill, requiring a siege. When "his engineers pointed out to him that because of the height of the mound it would be impossible… this encouraged Alexander all the more to make the attempt". After three unsuccessful assaults, the stronghold fell, but not before Alexander had received a serious shoulder wound. As in Tyre, men of military age were put to the sword and the women and children were sold into slavery.Alexander advanced on Egypt in later 332 BC, where he was regarded as a liberator. He was pronounced son of the deity Amun at the Oracle of Siwa Oasis in the Libyan desert. Henceforth, Alexander often referred to Zeus-Ammon as his true father, and after his death, currency depicted him adorned with the horns of a ram as a symbol of his divinity. During his stay in Egypt, he founded Alexandria-by-Egypt, which would become the prosperous capital of the Ptolemaic Kingdom after his death. === Assyria and Babylonia === Leaving Egypt in 331 BC, Alexander marched eastward into Mesopotamia (now northern Iraq) and again defeated Darius, at the Battle of Gaugamela. Darius once more fled the field, and Alexander chased him as far as Arbela. Gaugamela would be the final and decisive encounter between the two. Darius fled over the mountains to Ecbatana (modern Hamedan), while Alexander captured Babylon. === Persia === From Babylon, Alexander went to Susa, one of the Achaemenid capitals, and captured its treasury. He sent the bulk of his army to the Persian ceremonial capital of Persepolis via the Persian Royal Road. Alexander himself took selected troops on the direct route to the city. He then stormed the pass of the Persian Gates (in the modern Zagros Mountains) which had been blocked by a Persian army under Ariobarzanes and then hurried to Persepolis before its garrison could loot the treasury.On entering Persepolis, Alexander allowed his troops to loot the city for several days. Alexander stayed in Persepolis for five months. During his stay a fire broke out in the eastern palace of Xerxes I and spread to the rest of the city. Possible causes include a drunken accident or deliberate revenge for the burning of the Acropolis of Athens during the Second Persian War by Xerxes. Even as he watched the city burn, Alexander immediately began to regret his decision. Plutarch claims that he ordered his men to put out the fires, but that the flames had already spread to most of the city. Curtius claims that Alexander did not regret his decision until the next morning. Plutarch recounts an anecdote in which Alexander pauses and talks to a fallen statue of Xerxes as if it were a live person: Shall I pass by and leave you lying there because of the expeditions you led against Greece, or shall I set you up again because of your magnanimity and your virtues in other respects? === Fall of the Empire and the East === Alexander then chased Darius, first into Media, and then Parthia. The Persian king no longer controlled his own destiny, and was taken prisoner by Bessus, his Bactrian satrap and kinsman. As Alexander approached, Bessus had his men fatally stab the Great King and then declared himself Darius' successor as Artaxerxes V, before retreating into Central Asia to launch a guerrilla campaign against Alexander. Alexander buried Darius' remains next to his Achaemenid predecessors in a regal funeral. He claimed that, while dying, Darius had named him as his successor to the Achaemenid throne. The Achaemenid Empire is normally considered to have fallen with Darius.Alexander viewed Bessus as a usurper and set out to defeat him. This campaign, initially against Bessus, turned into a grand tour of central Asia. Alexander founded a series of new cities, all called Alexandria, including modern Kandahar in Afghanistan, and Alexandria Eschate ("The Furthest") in modern Tajikistan. The campaign took Alexander through Media, Parthia, Aria (West Afghanistan), Drangiana, Arachosia (South and Central Afghanistan), Bactria (North and Central Afghanistan), and Scythia.Spitamenes, who held an undefined position in the satrapy of Sogdiana, in 329 BC betrayed Bessus to Ptolemy, one of Alexander's trusted companions, and Bessus was executed. However, when, at some point later, Alexander was on the Jaxartes dealing with an incursion by a horse nomad army, Spitamenes raised Sogdiana in revolt. Alexander personally defeated the Scythians at the Battle of Jaxartes and immediately launched a campaign against Spitamenes, defeating him in the Battle of Gabai. After the defeat, Spitamenes was killed by his own men, who then sued for peace. === Problems and plots === During this time, Alexander adopted some elements of Persian dress and customs at his court, notably the custom of proskynesis, either a symbolic kissing of the hand, or prostration on the ground, that Persians showed to their social superiors. The Greeks regarded the gesture as the province of deities and believed that Alexander meant to deify himself by requiring it. This cost him the sympathies of many of his countrymen, and he eventually abandoned it.A plot against his life was revealed, and one of his officers, Philotas, was executed for failing to alert Alexander. The death of the son necessitated the death of the father, and thus Parmenion, who had been charged with guarding the treasury at Ecbatana, was assassinated at Alexander's command, to prevent attempts at vengeance. Most infamously, Alexander personally killed the man who had saved his life at Granicus, Cleitus the Black, during a violent drunken altercation at Maracanda (modern day Samarkand in Uzbekistan), in which Cleitus accused Alexander of several judgmental mistakes and most especially, of having forgotten the Macedonian ways in favour of a corrupt oriental lifestyle.Later, in the Central Asian campaign, a second plot against his life was revealed, this one instigated by his own royal pages. His official historian, Callisthenes of Olynthus, was implicated in the plot, and in the Anabasis of Alexander, Arrian states that Callisthenes and the pages were then tortured on the rack as punishment, and likely died soon after. It remains unclear if Callisthenes was actually involved in the plot, for prior to his accusation he had fallen out of favour by leading the opposition to the attempt to introduce proskynesis. === Macedon in Alexander's absence === When Alexander set out for Asia, he left his general Antipater, an experienced military and political leader and part of Philip II's "Old Guard", in charge of Macedon. Alexander's sacking of Thebes ensured that Greece remained quiet during his absence. The one exception was a call to arms by Spartan king Agis III in 331 BC, whom Antipater defeated and killed in the battle of Megalopolis. Antipater referred the Spartans' punishment to the League of Corinth, which then deferred to Alexander, who chose to pardon them. There was also considerable friction between Antipater and Olympias, and each complained to Alexander about the other.In general, Greece enjoyed a period of peace and prosperity during Alexander's campaign in Asia. Alexander sent back vast sums from his conquest, which stimulated the economy and increased trade across his empire. However, Alexander's constant demands for troops and the migration of Macedonians throughout his empire depleted Macedon's strength, greatly weakening it in the years after Alexander, and ultimately led to its subjugation by Rome after the Third Macedonian War (171–168 BC). == Indian campaign == === Forays into the Indian subcontinent === After the death of Spitamenes and his marriage to Roxana (Raoxshna in Old Iranian) to cement relations with his new satrapies, Alexander turned to the Indian subcontinent. He invited the chieftains of the former satrapy of Gandhara (a region presently straddling eastern Afghanistan and northern Pakistan), to come to him and submit to his authority. Omphis (Indian name Ambhi), the ruler of Taxila, whose kingdom extended from the Indus to the Hydaspes (Jhelum), complied, but the chieftains of some hill clans, including the Aspasioi and Assakenoi sections of the Kambojas (known in Indian texts also as Ashvayanas and Ashvakayanas), refused to submit. Ambhi hastened to relieve Alexander of his apprehension and met him with valuable presents, placing himself and all his forces at his disposal. Alexander not only returned Ambhi his title and the gifts but he also presented him with a wardrobe of "Persian robes, gold and silver ornaments, 30 horses and 1,000 talents in gold". Alexander was emboldened to divide his forces, and Ambhi assisted Hephaestion and Perdiccas in constructing a bridge over the Indus where it bends at Hund (Fox 1973), supplied their troops with provisions, and received Alexander himself, and his whole army, in his capital city of Taxila, with every demonstration of friendship and the most liberal hospitality. On the subsequent advance of the Macedonian king, Taxiles accompanied him with a force of 5,000 men and took part in the battle of the Hydaspes River. After that victory he was sent by Alexander in pursuit of Porus, to whom he was charged to offer favourable terms, but narrowly escaped losing his life at the hands of his old enemy. Subsequently, however, the two rivals were reconciled by the personal mediation of Alexander; and Taxiles, after having contributed zealously to the equipment of the fleet on the Hydaspes, was entrusted by the king with the government of the whole territory between that river and the Indus. A considerable accession of power was granted him after the death of Philip, son of Machatas; and he was allowed to retain his authority at the death of Alexander himself (323 BC), as well as in the subsequent partition of the provinces at Triparadisus, 321 BC. In the winter of 327/326 BC, Alexander personally led a campaign against these clans; the Aspasioi of Kunar valleys, the Guraeans of the Guraeus valley, and the Assakenoi of the Swat and Buner valleys. A fierce contest ensued with the Aspasioi in which Alexander was wounded in the shoulder by a dart, but eventually the Aspasioi lost. Alexander then faced the Assakenoi, who fought in the strongholds of Massaga, Ora and Aornos.The fort of Massaga was reduced only after days of bloody fighting, in which Alexander was wounded seriously in the ankle. According to Curtius, "Not only did Alexander slaughter the entire population of Massaga, but also did he reduce its buildings to rubble." A similar slaughter followed at Ora. In the aftermath of Massaga and Ora, numerous Assakenians fled to the fortress of Aornos. Alexander followed close behind and captured the strategic hill-fort after four bloody days.After Aornos, Alexander crossed the Indus and fought and won an epic battle against King Porus, who ruled a region lying between the Hydaspes and the Acesines (Chenab), in what is now the Punjab, in the Battle of the Hydaspes in 326 BC. Alexander was impressed by Porus' bravery, and made him an ally. He appointed Porus as satrap, and added to Porus' territory land that he did not previously own, towards the south-east, up to the Hyphasis (Beas). Choosing a local helped him control these lands so distant from Greece. Alexander founded two cities on opposite sides of the Hydaspes river, naming one Bucephala, in honour of his horse, who died around this time. The other was Nicaea (Victory), thought to be located at the site of modern-day Mong, Punjab. === Revolt of the army === East of Porus' kingdom, near the Ganges River, was the Nanda Empire of Magadha, and further east, the Gangaridai Empire of Bengal region of the Indian subcontinent. Fearing the prospect of facing other large armies and exhausted by years of campaigning, Alexander's army mutinied at the Hyphasis River (Beas), refusing to march farther east. This river thus marks the easternmost extent of Alexander's conquests. As for the Macedonians, however, their struggle with Porus blunted their courage and stayed their further advance into India. For having had all they could do to repulse an enemy who mustered only twenty thousand infantry and two thousand horse, they violently opposed Alexander when he insisted on crossing the river Ganges also, the width of which, as they learned, was thirty-two furlongs, its depth a hundred fathoms, while its banks on the further side were covered with multitudes of men-at-arms and horsemen and elephants. For they were told that the kings of the Ganderites and Praesii were awaiting them with eighty thousand horsemen, two hundred thousand footmen, eight thousand chariots, and six thousand war elephants. Alexander tried to persuade his soldiers to march farther, but his general Coenus pleaded with him to change his opinion and return; the men, he said, "longed to again see their parents, their wives and children, their homeland". Alexander eventually agreed and turned south, marching along the Indus. Along the way his army conquered the Malhi (in modern-day Multan) and other Indian tribes and Alexander sustained an injury during the siege. Alexander sent much of his army to Carmania (modern southern Iran) with general Craterus, and commissioned a fleet to explore the Persian Gulf shore under his admiral Nearchus, while he led the rest back to Persia through the more difficult southern route along the Gedrosian Desert and Makran. Alexander reached Susa in 324 BC, but not before losing many men to the harsh desert. == Last years in Persia == Discovering that many of his satraps and military governors had misbehaved in his absence, Alexander executed several of them as examples on his way to Susa. As a gesture of thanks, he paid off the debts of his soldiers, and announced that he would send over-aged and disabled veterans back to Macedon, led by Craterus. His troops misunderstood his intention and mutinied at the town of Opis. They refused to be sent away and criticized his adoption of Persian customs and dress and the introduction of Persian officers and soldiers into Macedonian units. After three days, unable to persuade his men to back down, Alexander gave Persians command posts in the army and conferred Macedonian military titles upon Persian units. The Macedonians quickly begged forgiveness, which Alexander accepted, and held a great banquet for several thousand of his men at which he and they ate together. In an attempt to craft a lasting harmony between his Macedonian and Persian subjects, Alexander held a mass marriage of his senior officers to Persian and other noblewomen at Susa, but few of those marriages seem to have lasted much beyond a year. Meanwhile, upon his return to Persia, Alexander learned that guards of the tomb of Cyrus the Great in Pasargadae had desecrated it, and swiftly executed them. Alexander admired Cyrus the Great, from an early age reading Xenophon's Cyropaedia, which described Cyrus's heroism in battle and governance as a king and legislator. During his visit to Pasargadae Alexander ordered his architect Aristobulus to decorate the interior of the sepulchral chamber of Cyrus' tomb.Afterwards, Alexander travelled to Ecbatana to retrieve the bulk of the Persian treasure. There, his closest friend and possible lover, Hephaestion, died of illness or poisoning. Hephaestion's death devastated Alexander, and he ordered the preparation of an expensive funeral pyre in Babylon, as well as a decree for public mourning. Back in Babylon, Alexander planned a series of new campaigns, beginning with an invasion of Arabia, but he would not have a chance to realize them, as he died shortly thereafter. == Death and succession == On either 10 or 11 June 323 BC, Alexander died in the palace of Nebuchadnezzar II, in Babylon, at age 32. There are two different versions of Alexander's death and details of the death differ slightly in each. Plutarch's account is that roughly 14 days before his death, Alexander entertained admiral Nearchus, and spent the night and next day drinking with Medius of Larissa. He developed a fever, which worsened until he was unable to speak. The common soldiers, anxious about his health, were granted the right to file past him as he silently waved at them. In the second account, Diodorus recounts that Alexander was struck with pain after downing a large bowl of unmixed wine in honour of Heracles, followed by 11 days of weakness; he did not develop a fever and died after some agony. Arrian also mentioned this as an alternative, but Plutarch specifically denied this claim.Given the propensity of the Macedonian aristocracy to assassination, foul play featured in multiple accounts of his death. Diodorus, Plutarch, Arrian and Justin all mentioned the theory that Alexander was poisoned. Justin stated that Alexander was the victim of a poisoning conspiracy, Plutarch dismissed it as a fabrication, while both Diodorus and Arrian noted that they mentioned it only for the sake of completeness. The accounts were nevertheless fairly consistent in designating Antipater, recently removed as Macedonian viceroy, and at odds with Olympias, as the head of the alleged plot. Perhaps taking his summons to Babylon as a death sentence, and having seen the fate of Parmenion and Philotas, Antipater purportedly arranged for Alexander to be poisoned by his son Iollas, who was Alexander's wine-pourer. There was even a suggestion that Aristotle may have participated.The strongest argument against the poison theory is the fact that twelve days passed between the start of his illness and his death; such long-acting poisons were probably not available. However, in a 2003 BBC documentary investigating the death of Alexander, Leo Schep from the New Zealand National Poisons Centre proposed that the plant white hellebore (Veratrum album), which was known in antiquity, may have been used to poison Alexander. In a 2014 manuscript in the journal Clinical Toxicology, Schep suggested Alexander's wine was spiked with Veratrum album, and that this would produce poisoning symptoms that match the course of events described in the Alexander Romance. Veratrum album poisoning can have a prolonged course and it was suggested that if Alexander was poisoned, Veratrum album offers the most plausible cause. Another poisoning explanation put forward in 2010 proposed that the circumstances of his death were compatible with poisoning by water of the river Styx (modern-day Mavroneri in Arcadia, Greece) that contained calicheamicin, a dangerous compound produced by bacteria.Several natural causes (diseases) have been suggested, including malaria and typhoid fever. A 1998 article in the New England Journal of Medicine attributed his death to typhoid fever complicated by bowel perforation and ascending paralysis. Another recent analysis suggested pyogenic (infectious) spondylitis or meningitis. Other illnesses fit the symptoms, including acute pancreatitis and West Nile virus. Natural-cause theories also tend to emphasize that Alexander's health may have been in general decline after years of heavy drinking and severe wounds. The anguish that Alexander felt after Hephaestion's death may also have contributed to his declining health. === After death === Alexander's body was laid in a gold anthropoid sarcophagus that was filled with honey, which was in turn placed in a gold casket. According to Aelian, a seer called Aristander foretold that the land where Alexander was laid to rest "would be happy and unvanquishable forever". Perhaps more likely, the successors may have seen possession of the body as a symbol of legitimacy, since burying the prior king was a royal prerogative.While Alexander's funeral cortege was on its way to Macedon, Ptolemy seized it and took it temporarily to Memphis. His successor, Ptolemy II Philadelphus, transferred the sarcophagus to Alexandria, where it remained until at least late Antiquity. Ptolemy IX Lathyros, one of Ptolemy's final successors, replaced Alexander's sarcophagus with a glass one so he could convert the original to coinage. The recent discovery of an enormous tomb in northern Greece, at Amphipolis, dating from the time of Alexander the Great has given rise to speculation that its original intent was to be the burial place of Alexander. This would fit with the intended destination of Alexander's funeral cortege. Pompey, Julius Caesar and Augustus all visited the tomb in Alexandria, where Augustus, allegedly, accidentally knocked the nose off. Caligula was said to have taken Alexander's breastplate from the tomb for his own use. Around AD 200, Emperor Septimius Severus closed Alexander's tomb to the public. His son and successor, Caracalla, a great admirer, visited the tomb during his own reign. After this, details on the fate of the tomb are hazy.The so-called "Alexander Sarcophagus", discovered near Sidon and now in the Istanbul Archaeology Museum, is so named not because it was thought to have contained Alexander's remains, but because its bas-reliefs depict Alexander and his companions fighting the Persians and hunting. It was originally thought to have been the sarcophagus of Abdalonymus (died 311 BC), the king of Sidon appointed by Alexander immediately following the battle of Issus in 331. However, more recently, it has been suggested that it may date from earlier than Abdalonymus' death. === Division of the empire === Alexander's death was so sudden that when reports of his death reached Greece, they were not immediately believed. Alexander had no obvious or legitimate heir, his son Alexander IV by Roxane being born after Alexander's death. According to Diodorus, Alexander's companions asked him on his deathbed to whom he bequeathed his kingdom; his laconic reply was "tôi kratistôi"—"to the strongest". Another theory is that his successors willfully or erroneously misheard "tôi Kraterôi"—"to Craterus", the general leading his Macedonian troops home and newly entrusted with the regency of Macedonia.Arrian and Plutarch claimed that Alexander was speechless by this point, implying that this was an apocryphal story. Diodorus, Curtius and Justin offered the more plausible story that Alexander passed his signet ring to Perdiccas, a bodyguard and leader of the companion cavalry, in front of witnesses, thereby nominating him.Perdiccas initially did not claim power, instead suggesting that Roxane's baby would be king, if male; with himself, Craterus, Leonnatus, and Antipater as guardians. However, the infantry, under the command of Meleager, rejected this arrangement since they had been excluded from the discussion. Instead, they supported Alexander's half-brother Philip Arrhidaeus. Eventually, the two sides reconciled, and after the birth of Alexander IV, he and Philip III were appointed joint kings, albeit in name only.Dissension and rivalry soon afflicted the Macedonians, however. The satrapies handed out by Perdiccas at the Partition of Babylon became power bases each general used to bid for power. After the assassination of Perdiccas in 321 BC, Macedonian unity collapsed, and 40 years of war between "The Successors" (Diadochi) ensued before the Hellenistic world settled into four stable power blocks: Ptolemaic Egypt, Seleucid Mesopotamia and Central Asia, Attalid Anatolia, and Antigonid Macedon. In the process, both Alexander IV and Philip III were murdered. === Will === Diodorus stated that Alexander had given detailed written instructions to Craterus some time before his death. Craterus started to carry out Alexander's commands, but the successors chose not to further implement them, on the grounds they were impractical and extravagant. Nevertheless, Perdiccas read Alexander's will to his troops.Alexander's will called for military expansion into the southern and western Mediterranean, monumental constructions, and the intermixing of Eastern and Western populations. It included: Construction of a monumental tomb for his father Philip, “to match the greatest of the pyramids of Egypt” Erection of great temples in Delos, Delphi, Dodona, Dium, Amphipolis, and a monumental temple to Athena at Troy Conquest of Arabia and the entire Mediterranean Basin Circumnavigation of Africa Development of cities and the “transplant of populations from Asia to Europe and in the opposite direction from Europe to Asia, in order to bring the largest continent to common unity and to friendship by means of intermarriage and family ties.” == Character == === Generalship === Alexander earned the epithet "the Great" due to his unparalleled success as a military commander. He never lost a battle, despite typically being outnumbered. This was due to use of terrain, phalanx and cavalry tactics, bold strategy, and the fierce loyalty of his troops. The Macedonian phalanx, armed with the sarissa, a spear 6 metres (20 ft) long, had been developed and perfected by Philip II through rigorous training, and Alexander used its speed and maneuverability to great effect against larger but more disparate Persian forces. Alexander also recognized the potential for disunity among his diverse army, which employed various languages and weapons. He overcame this by being personally involved in battle, in the manner of a Macedonian king.In his first battle in Asia, at Granicus, Alexander used only a small part of his forces, perhaps 13,000 infantry with 5,000 cavalry, against a much larger Persian force of 40,000. Alexander placed the phalanx at the center and cavalry and archers on the wings, so that his line matched the length of the Persian cavalry line, about 3 km (1.86 mi). By contrast, the Persian infantry was stationed behind its cavalry. This ensured that Alexander would not be outflanked, while his phalanx, armed with long pikes, had a considerable advantage over the Persians' scimitars and javelins. Macedonian losses were negligible compared to those of the Persians.At Issus in 333 BC, his first confrontation with Darius, he used the same deployment, and again the central phalanx pushed through. Alexander personally led the charge in the center, routing the opposing army. At the decisive encounter with Darius at Gaugamela, Darius equipped his chariots with scythes on the wheels to break up the phalanx and equipped his cavalry with pikes. Alexander arranged a double phalanx, with the center advancing at an angle, parting when the chariots bore down and then reforming. The advance was successful and broke Darius' center, causing the latter to flee once again.When faced with opponents who used unfamiliar fighting techniques, such as in Central Asia and India, Alexander adapted his forces to his opponents' style. Thus, in Bactria and Sogdiana, Alexander successfully used his javelin throwers and archers to prevent outflanking movements, while massing his cavalry at the center. In India, confronted by Porus' elephant corps, the Macedonians opened their ranks to envelop the elephants and used their sarissas to strike upwards and dislodge the elephants' handlers. === Physical appearance === Greek biographer Plutarch (c.  45 – c. 120 AD) describes Alexander's appearance as: ¹ The outward appearance of Alexander is best represented by the statues of him which Lysippus made, and it was by this artist alone that Alexander himself thought it fit that he should be modelled. ² For those peculiarities which many of his successors and friends afterwards tried to imitate, namely, the poise of the neck, which was bent slightly to the left, and the melting glance of his eyes, this artist has accurately observed. ³ Apelles, however, in painting him as wielder of the thunder-bolt, did not reproduce his complexion, but made it too dark and swarthy. Whereas he was of a fair colour, as they say, and his fairness passed into ruddiness on his breast particularly, and in his face. 4 Moreover, that a very pleasant odour exhaled from his skin and that there was a fragrance about his mouth and all his flesh, so that his garments were filled with it, this we have read in the Memoirs of Aristoxenus. Greek historian Arrian (Lucius Flavius Arrianus 'Xenophon' c.  86 – c. 160 AD) described Alexander as: [T]he strong, handsome commander with one eye dark as the night and one blue as the sky. The semi-legendary Alexander Romance also suggests that Alexander exhibited heterochromia iridum: that one eye was dark and the other light.British historian Peter Green provided a description of Alexander's appearance, based on his review of statues and some ancient documents: Physically, Alexander was not prepossessing. Even by Macedonian standards he was very short, though stocky and tough. His beard was scanty, and he stood out against his hirsute Macedonian barons by going clean-shaven. His neck was in some way twisted, so that he appeared to be gazing upward at an angle. His eyes (one blue, one brown) revealed a dewy, feminine quality. He had a high complexion and a harsh voice. Ancient authors recorded that Alexander was so pleased with portraits of himself created by Lysippos that he forbade other sculptors from crafting his image. Lysippos had often used the contrapposto sculptural scheme to portray Alexander and other characters such as Apoxyomenos, Hermes and Eros. Lysippos' sculpture, famous for its naturalism, as opposed to a stiffer, more static pose, is thought to be the most faithful depiction. === Personality === Some of Alexander's strongest personality traits formed in response to his parents. His mother had huge ambitions, and encouraged him to believe it was his destiny to conquer the Persian Empire. Olympias' influence instilled a sense of destiny in him, and Plutarch tells how his ambition "kept his spirit serious and lofty in advance of his years". However, his father Philip was Alexander's most immediate and influential role model, as the young Alexander watched him campaign practically every year, winning victory after victory while ignoring severe wounds. Alexander's relationship with his father forged the competitive side of his personality; he had a need to out-do his father, illustrated by his reckless behaviour in battle. While Alexander worried that his father would leave him "no great or brilliant achievement to be displayed to the world", he also downplayed his father's achievements to his companions. According to Plutarch, among Alexander's traits were a violent temper and rash, impulsive nature, which undoubtedly contributed to some of his decisions. Although Alexander was stubborn and did not respond well to orders from his father, he was open to reasoned debate. He had a calmer side—perceptive, logical, and calculating. He had a great desire for knowledge, a love for philosophy, and was an avid reader. This was no doubt in part due to Aristotle's tutelage; Alexander was intelligent and quick to learn. His intelligent and rational side was amply demonstrated by his ability and success as a general. He had great self-restraint in "pleasures of the body", in contrast with his lack of self-control with alcohol.Alexander was erudite and patronized both arts and sciences. However, he had little interest in sports or the Olympic games (unlike his father), seeking only the Homeric ideals of honour (timê) and glory (kudos). He had great charisma and force of personality, characteristics which made him a great leader. His unique abilities were further demonstrated by the inability of any of his generals to unite Macedonia and retain the Empire after his death—only Alexander had the ability to do so.During his final years, and especially after the death of Hephaestion, Alexander began to exhibit signs of megalomania and paranoia. His extraordinary achievements, coupled with his own ineffable sense of destiny and the flattery of his companions, may have combined to produce this effect. His delusions of grandeur are readily visible in his will and in his desire to conquer the world, in as much as he is by various sources described as having boundless ambition, an epithet, the meaning of which has descended into an historical cliché.He appears to have believed himself a deity, or at least sought to deify himself. Olympias always insisted to him that he was the son of Zeus, a theory apparently confirmed to him by the oracle of Amun at Siwa. He began to identify himself as the son of Zeus-Ammon. Alexander adopted elements of Persian dress and customs at court, notably proskynesis, a practice of which Macedonians disapproved, and were loath to perform. This behaviour cost him the sympathies of many of his countrymen. However, Alexander also was a pragmatic ruler who understood the difficulties of ruling culturally disparate peoples, many of whom lived in kingdoms where the king was divine. Thus, rather than megalomania, his behaviour may simply have been a practical attempt at strengthening his rule and keeping his empire together. === Personal relationships === Alexander married three times: Roxana, daughter of the Sogdian nobleman Oxyartes of Bactria, out of love; and the Persian princesses Stateira II and Parysatis II, the former a daughter of Darius III and latter a daughter of Artaxerxes III, for political reasons. He apparently had two sons, Alexander IV of Macedon by Roxana and, possibly, Heracles of Macedon from his mistress Barsine. He lost another child when Roxana miscarried at Babylon.Alexander also had a close relationship with his friend, general, and bodyguard Hephaestion, the son of a Macedonian noble. Hephaestion's death devastated Alexander. This event may have contributed to Alexander's failing health and detached mental state during his final months.Alexander's sexuality has been the subject of speculation and controversy. No ancient sources stated that Alexander had homosexual relationships, or that Alexander's relationship with Hephaestion was sexual. Aelian, however, writes of Alexander's visit to Troy where "Alexander garlanded the tomb of Achilles and Hephaestion that of Patroclus, the latter riddling that he was a beloved of Alexander, in just the same way as Patroclus was of Achilles." Noting that the word eromenos (ancient Greek for beloved) does not necessarily bear sexual meaning. Alexander may have been bisexual, in keeping with Greek upper class custom.Green argues that there is little evidence in ancient sources that Alexander had much carnal interest in women; he did not produce an heir until the very end of his life. However, he was relatively young when he died, and Ogden suggests that Alexander's matrimonial record is more impressive than his father's at the same age. Apart from wives, Alexander had many more female companions. Alexander accumulated a harem in the style of Persian kings, but he used it rather sparingly, showing great self-control in "pleasures of the body". Nevertheless, Plutarch described how Alexander was infatuated by Roxana while complimenting him on not forcing himself on her. Green suggested that, in the context of the period, Alexander formed quite strong friendships with women, including Ada of Caria, who adopted him, and even Darius' mother Sisygambis, who supposedly died from grief upon hearing of Alexander's death. == Battle record == == Legacy == Alexander's legacy extended beyond his military conquests. His campaigns greatly increased contacts and trade between East and West, and vast areas to the east were significantly exposed to Greek civilization and influence. Some of the cities he founded became major cultural centers, many surviving into the 21st century. His chroniclers recorded valuable information about the areas through which he marched, while the Greeks themselves got a sense of belonging to a world beyond the Mediterranean. === Hellenistic kingdoms === Alexander's most immediate legacy was the introduction of Macedonian rule to huge new swathes of Asia. At the time of his death, Alexander's empire covered some 5,200,000 km2 (2,000,000 sq mi), and was the largest state of its time. Many of these areas remained in Macedonian hands or under Greek influence for the next 200–300 years. The successor states that emerged were, at least initially, dominant forces, and these 300 years are often referred to as the Hellenistic period.The eastern borders of Alexander's empire began to collapse even during his lifetime. However, the power vacuum he left in the northwest of the Indian subcontinent directly gave rise to one of the most powerful Indian dynasties in history, the Maurya Empire. Taking advantage of this power vacuum, Chandragupta Maurya (referred to in Greek sources as "Sandrokottos"), of relatively humble origin, took control of the Punjab, and with that power base proceeded to conquer the Nanda Empire. === Founding of cities === Over the course of his conquests, Alexander founded some twenty cities that bore his name, most of them east of the Tigris. The first, and greatest, was Alexandria in Egypt, which would become one of the leading Mediterranean cities. The cities' locations reflected trade routes as well as defensive positions. At first, the cities must have been inhospitable, little more than defensive garrisons. Following Alexander's death, many Greeks who had settled there tried to return to Greece. However, a century or so after Alexander's death, many of the Alexandrias were thriving, with elaborate public buildings and substantial populations that included both Greek and local peoples. === Funding of temples === In 334 BC, Alexander the Great donated funds for the completion of the new temple of Athena Polias in Priene. An inscription from the temple, now housed in the British Museum, declares: "King Alexander dedicated [this temple] to Athena Polias." This inscription is one of the few independent archaeological discoveries confirming an episode from Alexander's life. The temple was designed by Pytheos, one of the architects of the Mausoleum at Halicarnassus. === Hellenization === Hellenization was coined by the German historian Johann Gustav Droysen to denote the spread of Greek language, culture, and population into the former Persian empire after Alexander's conquest. That this export took place is undoubted, and can be seen in the great Hellenistic cities of, for instance, Alexandria, Antioch and Seleucia (south of modern Baghdad). Alexander sought to insert Greek elements into Persian culture and attempted to hybridize Greek and Persian culture. This culminated in his aspiration to homogenize the populations of Asia and Europe. However, his successors explicitly rejected such policies. Nevertheless, Hellenization occurred throughout the region, accompanied by a distinct and opposite 'Orientalization' of the successor states.The core of the Hellenistic culture promulgated by the conquests was essentially Athenian. The close association of men from across Greece in Alexander's army directly led to the emergence of the largely Attic-based "koine", or "common" Greek dialect. Koine spread throughout the Hellenistic world, becoming the lingua franca of Hellenistic lands and eventually the ancestor of modern Greek. Furthermore, town planning, education, local government, and art current in the Hellenistic period were all based on Classical Greek ideals, evolving into distinct new forms commonly grouped as Hellenistic. Aspects of Hellenistic culture were still evident in the traditions of the Byzantine Empire in the mid-15th century. Some of the most pronounced effects of Hellenization can be seen in Afghanistan and India, in the region of the relatively late-rising Greco-Bactrian Kingdom (250–125 BC) (in modern Afghanistan, Pakistan, and Tajikistan) and the Indo-Greek Kingdom (180 BC – 10 AD) in modern Afghanistan and India. There on the newly formed Silk Road Greek culture apparently hybridized with Indian, and especially Buddhist culture. The resulting syncretism known as Greco-Buddhism heavily influenced the development of Buddhism and created a culture of Greco-Buddhist art. These Greco-Buddhist kingdoms sent some of the first Buddhist missionaries to China, Sri Lanka, and the Mediterranean (Greco-Buddhist monasticism). Some of the first and most influential figurative portrayals of the Buddha appeared at this time, perhaps modeled on Greek statues of Apollo in the Greco-Buddhist style. Several Buddhist traditions may have been influenced by the ancient Greek religion: the concept of Boddhisatvas is reminiscent of Greek divine heroes, and some Mahayana ceremonial practices (burning incense, gifts of flowers, and food placed on altars) are similar to those practiced by the ancient Greeks; however, similar practices were also observed amongst the native Indic culture. One Greek king, Menander I, probably became Buddhist, and was immortalized in Buddhist literature as 'Milinda'. The process of Hellenization also spurred trade between the east and west. For example, Greek astronomical instruments dating to the 3rd century BC were found in the Greco-Bactrian city of Ai Khanoum in modern-day Afghanistan, while the Greek concept of a spherical earth surrounded by the spheres of planets eventually supplanted the long-standing Indian cosmological belief of a disc consisting of four continents grouped around a central mountain (Mount Meru) like the petals of a flower. The Yavanajataka (lit. Greek astronomical treatise) and Paulisa Siddhanta texts depict the influence of Greek astronomical ideas on Indian astronomy. Following the conquests of Alexander the Great in the east, Hellenistic influence on Indian art was far-ranging. In the area of architecture, a few examples of the Ionic order can be found as far as Pakistan with the Jandial temple near Taxila. Several examples of capitals displaying Ionic influences can be seen as far as Patna, especially with the Pataliputra capital, dated to the 3rd century BC. The Corinthian order is also heavily represented in the art of Gandhara, especially through Indo-Corinthian capitals. === Influence on Rome === Alexander and his exploits were admired by many Romans, especially generals, who wanted to associate themselves with his achievements. Polybius began his Histories by reminding Romans of Alexander's achievements, and thereafter Roman leaders saw him as a role model. Pompey the Great adopted the epithet "Magnus" and even Alexander's anastole-type haircut, and searched the conquered lands of the east for Alexander's 260-year-old cloak, which he then wore as a sign of greatness. Julius Caesar dedicated a Lysippean equestrian bronze statue but replaced Alexander's head with his own, while Octavian visited Alexander's tomb in Alexandria and temporarily changed his seal from a sphinx to Alexander's profile. The emperor Trajan also admired Alexander, as did Nero and Caracalla. The Macriani, a Roman family that in the person of Macrinus briefly ascended to the imperial throne, kept images of Alexander on their persons, either on jewelry, or embroidered into their clothes. On the other hand, some Roman writers, particularly Republican figures, used Alexander as a cautionary tale of how autocratic tendencies can be kept in check by republican values. Alexander was used by these writers as an example of ruler values such as amicita (friendship) and clementia (clemency), but also iracundia (anger) and cupiditas gloriae (over-desire for glory). === Legend === Legendary accounts surround the life of Alexander the Great, many deriving from his own lifetime, probably encouraged by Alexander himself. His court historian Callisthenes portrayed the sea in Cilicia as drawing back from him in proskynesis. Writing shortly after Alexander's death, another participant, Onesicritus, invented a tryst between Alexander and Thalestris, queen of the mythical Amazons. When Onesicritus read this passage to his patron, Alexander's general and later King Lysimachus reportedly quipped, "I wonder where I was at the time."In the first centuries after Alexander's death, probably in Alexandria, a quantity of the legendary material coalesced into a text known as the Alexander Romance, later falsely ascribed to Callisthenes and therefore known as Pseudo-Callisthenes. This text underwent numerous expansions and revisions throughout Antiquity and the Middle Ages, containing many dubious stories, and was translated into numerous languages. === In ancient and modern culture === Alexander the Great's accomplishments and legacy have been depicted in many cultures. Alexander has figured in both high and popular culture beginning in his own era to the present day. The Alexander Romance, in particular, has had a significant impact on portrayals of Alexander in later cultures, from Persian to medieval European to modern Greek.Alexander features prominently in modern Greek folklore, more so than any other ancient figure. The colloquial form of his name in modern Greek ("O Megalexandros") is a household name, and he is the only ancient hero to appear in the Karagiozis shadow play. One well-known fable among Greek seamen involves a solitary mermaid who would grasp a ship's prow during a storm and ask the captain "Is King Alexander alive?" The correct answer is "He is alive and well and rules the world!" causing the mermaid to vanish and the sea to calm. Any other answer would cause the mermaid to turn into a raging Gorgon who would drag the ship to the bottom of the sea, all hands aboard.In pre-Islamic Middle Persian (Zoroastrian) literature, Alexander is referred to by the epithet gujastak, meaning "accursed", and is accused of destroying temples and burning the sacred texts of Zoroastrianism. In Sunni Islamic Persia, under the influence of the Alexander Romance (in Persian: اسکندرنامه‎ Iskandarnamah), a more positive portrayal of Alexander emerges. Firdausi's Shahnameh ("The Book of Kings") includes Alexander in a line of legitimate Persian shahs, a mythical figure who explored the far reaches of the world in search of the Fountain of Youth. Later Persian writers associate him with philosophy, portraying him at a symposium with figures such as Socrates, Plato and Aristotle, in search of immortality. The figure of Dhul-Qarnayn (literally "the Two-Horned One") mentioned in the Quran is believed by some scholars to represent Alexander, due to parallels with the Alexander Romance. In this tradition, he was a heroic figure who built a wall to defend against the nations of Gog and Magog. He then travelled the known world in search of the Water of Life and Immortality, eventually becoming a prophet.The Syriac version of the Alexander Romance portrays him as an ideal Christian world conqueror who prayed to "the one true God". In Egypt, Alexander was portrayed as the son of Nectanebo II, the last pharaoh before the Persian conquest. His defeat of Darius was depicted as Egypt's salvation, "proving" Egypt was still ruled by an Egyptian.According to Josephus, Alexander was shown the Book of Daniel when he entered Jerusalem, which described a mighty Greek king who would conquer the Persian Empire. This is cited as a reason for sparing Jerusalem.In Hindi and Urdu, the name "Sikandar", derived from Persian, denotes a rising young talent. In medieval Europe, Alexander the Great was revered as a member of the Nine Worthies, a group of heroes whose lives were believed to encapsulate all the ideal qualities of chivalry.Irish playwright Aubrey Thomas de Vere wrote Alexander the Great, a Dramatic Poem. == Historiography == Apart from a few inscriptions and fragments, texts written by people who actually knew Alexander or who gathered information from men who served with Alexander were all lost. Contemporaries who wrote accounts of his life included Alexander's campaign historian Callisthenes; Alexander's generals Ptolemy and Nearchus; Aristobulus, a junior officer on the campaigns; and Onesicritus, Alexander's chief helmsman. Their works are lost, but later works based on these original sources have survived. The earliest of these is Diodorus Siculus (1st century BC), followed by Quintus Curtius Rufus (mid-to-late 1st century AD), Arrian (1st to 2nd century AD), the biographer Plutarch (1st to 2nd century AD), and finally Justin, whose work dated as late as the 4th century. Of these, Arrian is generally considered the most reliable, given that he used Ptolemy and Aristobulus as his sources, closely followed by Diodorus. == Ancestry == == See also == Alexander the Great in the Qur'an Ancient Macedonian army Bucephalus Chronology of European exploration of Asia Diogenes and Alexander Ptolemaic cult of Alexander the Great List of people known as The Great The Mahabharata Quest: The Alexander Secret == Annotations == == References == == Sources == == Further reading == == External links == Alexander the Great (king of Macedonia) at Encyclopædia Britannica Delamarche, Félix (1833), The Empire and Expeditions of Alexander the Great .

### Instruction: retrieve labels for this: Alfred Habdank Skarbek Korzybski ([kɔˈʐɨpski]; July 3, 1879 – March 1, 1950) was a Polish-American independent scholar who developed a field called general semantics, which he viewed as both distinct from, and more encompassing than, the field of semantics. He argued that human knowledge of the world is limited both by the human nervous system and the languages humans have developed, and thus no one can have direct access to reality, given that the most we can know is that which is filtered through the brain's responses to reality. His best known dictum is "The map is not the territory". == Early life and career == Born in Warsaw, Poland, then part of the Russian Empire, Korzybski belonged to an aristocratic Polish family whose members had worked as mathematicians, scientists, and engineers for generations. He learned the Polish language at home and the Russian language in schools; and having a French governess and a German governess, he became fluent in four languages as a child. Korzybski studied engineering at the Warsaw University of Technology. During the First World War (1914-1918) Korzybski served as an intelligence officer in the Russian Army. After being wounded in a leg and suffering other injuries, he moved to North America in 1916 (first to Canada, then to the United States) to coordinate the shipment of artillery to Russia. He also lectured to Polish-American audiences about the conflict, promoting the sale of war bonds. After the war he decided to remain in the United States, becoming a naturalized citizen in 1940. He met Mira Edgerly, a painter of portraits on ivory, shortly after the 1918 Armistice; They married in January 1919; the marriage lasted until his death. E. P. Dutton published Korzybski's first book, Manhood of Humanity, in 1921. In this work he proposed and explained in detail a new theory of humankind: mankind as a "time-binding" class of life (humans perform time binding by the transmission of knowledge and abstractions through time which become accreted in cultures). == General semantics == Korzybski's work culminated in the initiation of a discipline that he named general semantics (GS). This should not be confused with semantics. The basic principles of general semantics, which include time-binding, are described in the publication Science and Sanity, published in 1933. In 1938 Korzybski founded the Institute of General Semantics in Chicago. The post-World War II housing shortage in Chicago cost him the Institute's building lease, so in 1946 he moved the Institute to Lakeville, Connecticut, U.S., where he directed it until his death in 1950. Korzybski maintained that humans are limited in what they know by (1) the structure of their nervous systems, and (2) the structure of their languages. Humans cannot experience the world directly, but only through their "abstractions" (nonverbal impressions or "gleanings" derived from the nervous system, and verbal indicators expressed and derived from language). These sometimes mislead us about what is the truth. Our understanding sometimes lacks similarity of structure with what is actually happening. He sought to train our awareness of abstracting, using techniques he had derived from his study of mathematics and science. He called this awareness, this goal of his system, "consciousness of abstracting". His system included the promotion of attitudes such as "I don't know; let's see," in order that we may better discover or reflect on its realities as revealed by modern science. Another technique involved becoming inwardly and outwardly quiet, an experience he termed, "silence on the objective levels". == "To be" == Many devotees and critics of Korzybski reduced his rather complex system to a simple matter of what he said about the verb form "is" of the general verb "to be." His system, however, is based primarily on such terminology as the different "orders of abstraction," and formulations such as "consciousness of abstracting." It is often said that Korzybski opposed the use of the verb "to be." This is a profound exaggeration. He thought that certain uses of the verb "to be", called the "is of identity" and the "is of predication", were faulty in structure, e.g., a statement such as, "Elizabeth is a fool" (said of a person named "Elizabeth" who has done something that we regard as foolish). In Korzybski's system, one's assessment of Elizabeth belongs to a higher order of abstraction than Elizabeth herself. Korzybski's remedy was to deny identity; in this example, to be aware continually that "Elizabeth" is not what we call her. We find Elizabeth not in the verbal domain, the world of words, but the nonverbal domain (the two, he said, amount to different orders of abstraction). This was expressed by Korzybski's most famous premise, "the map is not the territory". Note that this premise uses the phrase "is not", a form of "to be"; this and many other examples show that he did not intend to abandon "to be" as such. In fact, he said explicitly that there were no structural problems with the verb "to be" when used as an auxiliary verb or when used to state existence or location. It was even acceptable at times to use the faulty forms of the verb "to be," as long as one was aware of their structural limitations. == Anecdotes == One day, Korzybski was giving a lecture to a group of students, and he interrupted the lesson suddenly in order to retrieve a packet of biscuits, wrapped in white paper, from his briefcase. He muttered that he just had to eat something, and he asked the students on the seats in the front row if they would also like a biscuit. A few students took a biscuit. "Nice biscuit, don't you think," said Korzybski, while he took a second one. The students were chewing vigorously. Then he tore the white paper from the biscuits, in order to reveal the original packaging. On it was a big picture of a dog's head and the words "Dog Cookies." The students looked at the package, and were shocked. Two of them wanted to vomit, put their hands in front of their mouths, and ran out of the lecture hall to the toilet. "You see," Korzybski remarked, "I have just demonstrated that people don't just eat food, but also words, and that the taste of the former is often outdone by the taste of the latter."William Burroughs went to a Korzybski workshop in the Autumn of 1939. He was 25 years old, and paid $40. His fellow students—there were 38 in all—included young Samuel I. Hayakawa (later to become a Republican member of the U.S. Senate), Ralph Moriarty deBit (later to become the spiritual teacher Vitvan) and Wendell Johnson (founder of the Monster Study). == Influence == Korzybski was well received in numerous disciplines, as evidenced by the positive reactions from leading figures in the sciences and humanities in the 1940s and 1950s.As reported in the third edition of Science and Sanity, in World War II the US Army used Korzybski's system to treat battle fatigue in Europe, under the supervision of Dr. Douglas M. Kelley, who went on to become the psychiatrist in charge of the Nazi war criminals at Nuremberg. Some of the General Semantics tradition was continued by Samuel I. Hayakawa. == See also == == References == == Further reading == Kodish, Bruce. 2011. Korzybski: A Biography. Pasadena, CA: Extensional Publishing.

### Instruction: retrieve labels for this: The Alismatales (alismatids) are an order of flowering plants including about 4500 species. Plants assigned to this order are mostly tropical or aquatic. Some grow in fresh water, some in marine habitats. == Description == The Alismatales comprise herbaceous flowering plants of aquatic and marshy habitats, and the only monocots known to have green embryos other than the Amaryllidaceae. They also include the only marine angiosperms growing completely submerged, the seagrasses. The flowers are usually arranged in inflorescences, and the mature seeds lack endosperm. Both marine and freshwater forms include those with staminate flowers that detach from the parent plant and float to the surface where they become pollinated. In others, pollination occurs underwater, where pollen may form elongated strands, increasing chance of success. Most aquatic species have a totally submerged juvenile phase, and flowers are either floating or emergent. Vegetation may be totally submersed, have floating leaves, or protrude from the water. Collectively, they are commonly known as "water plantain". == Taxonomy == The Alismatales contain about 165 genera in 13 families, with a cosmopolitan distribution. Phylogenetically, they are basal monocots, diverging early in evolution relative to the lilioid and commelinid monocot lineages. Together with the Acorales, the Alismatales are referred to informally as the alismatid monocots. === Early systems === The Cronquist system (1981) places the Alismatales in subclass Alismatidae, class Liliopsida [= monocotyledons] and includes only three families as shown: Alismataceae Butomaceae LimnocharitaceaeCronquist's subclass Alismatidae conformed fairly closely to the order Alismatales as defined by APG, minus the Araceae. The Dahlgren system places the Alismatales in the superorder Alismatanae in the subclass Liliidae [= monocotyledons] in the class Magnoliopsida [= angiosperms] with the following families included: Alismataceae Aponogetonaceae Butomaceae Hydrocharitaceae LimnocharitaceaeIn Tahktajan's classification (1997), the order Alismatales contains only the Alismataceae and Limnocharitaceae, making it equivalent to the Alismataceae as revised in APG-III. Other families included in the Alismatates as currently defined are here distributed among 10 additional orders, all of which are assigned, with the following exception, to the Subclass Alismatidae. Araceae in Tahktajan 1997 is assigned to the Arales and placed in the Subclass Aridae; Tofieldiaceae to the Melanthiales and placed in the Liliidae. === Angiosperm Phylogeny Group === The Angiosperm Phylogeny Group system (APG) of 1998 and APG II (2003) assigned the Alismatales to the monocots, which may be thought of as an unranked clade containing the families listed below. The biggest departure from earlier systems (see below) is the inclusion of family Araceae. By its inclusion, the order has grown enormously in number of species. The family Araceae alone accounts for about a hundred genera, totaling over two thousand species. The rest of the families together contain only about five hundred species, many of which are in very small families.The APG III system (2009) differs only in that the Limnocharitaceae are combined with the Alismataceae; it was also suggested that the genus Maundia (of the Juncaginaceae) could be separated into a monogeneric family, the Maundiaceae, but the authors noted that more study was necessary before the Maundiaceae could be recognized. order Alismatales sensu APG III family Alismataceae (including Limnocharitaceae) family Aponogetonaceae family Araceae family Butomaceae family Cymodoceaceae family Hydrocharitaceae family Juncaginaceae family Posidoniaceae family Potamogetonaceae family Ruppiaceae family Scheuchzeriaceae family Tofieldiaceae family ZosteraceaeIn APG IV (2016), it was decided that evidence was sufficient to elevate Maundia to family level as the monogeneric Maundiaceae. The authors considered including a number of the smaller orders within the Juncaginaceae, but an online survey of botanists and other users found little support for this "lumping" approach. Consequently, the family structure for APG IV is: family Alismataceae (including Limnocharitaceae) family Aponogetonaceae family Araceae family Butomaceae family Cymodoceaceae family Hydrocharitaceae family Juncaginaceae family Maundiaceae family Posidoniaceae family Potamogetonaceae family Ruppiaceae family Scheuchzeriaceae family Tofieldiaceae family Zosteraceae === Phylogeny === Cladogram showing the orders of monocots (Lilianae sensu Chase & Reveal) based on molecular phylogenetic evidence: == References == == Further reading == == External links == ### Answer: <Alismatales>, <Angiosperm orders>

### Instruction: retrieve labels for this: The Apiales are an order of flowering plants. The families are those recognized in the APG III system. This is typical of the newer classifications, though there is some slight variation and in particular, the Torriceliaceae may be divided.Under this definition, well-known members include carrots, celery, parsley, and Hedera helix (English ivy). The order Apiales is placed within the asterid group of eudicots as circumscribed by the APG III system. Within the asterids, Apiales belongs to an unranked group called the campanulids, and within the campanulids, it belongs to a clade known in phylogenetic nomenclature as Apiidae. In 2010, a subclade of Apiidae named Dipsapiidae was defined to consist of the three orders: Apiales, Paracryphiales, and Dipsacales. == Taxonomy == Under the Cronquist system, only the Apiaceae and Araliaceae were included here, and the restricted order was placed among the rosids rather than the asterids. The Pittosporaceae were placed within the Rosales, and many of the other forms within the family Cornaceae. Pennantia was in the family Icacinaceae. In the classification system of Dahlgren the Apiaceae and Araliaceae families were placed in the order Ariales, in the superorder Araliiflorae (also called Aralianae). The present understanding of the Apiales is fairly recent and is based upon comparison of DNA sequences by phylogenetic methods. The circumscriptions of some of the families have changed. In 2009, one of the subfamilies of Araliaceae was shown to be polyphyletic. == Gynoecia == The largest and obviously closely related families of Apiales are Araliaceae, Myodocarpaceae and Apiaceae, which resemble each other in the structure of their gynoecia. In this respect however, the Pittosporaceae is notably distinct from them.Typical syncarpous gynoecia exhibit four vertical zones, determined by the extent of fusion of the carpels. In most plants the synascidiate (i.e. "united bottle-shaped") and symplicate zones are fertile and bear the ovules. Each of the first three families possess mainly bi- or multilocular ovaries in a gynoecium with a long synascidiate, but very short symplicate zone, where the ovules are inserted at their transition, the so-called cross-zone (or "Querzone").In gynoecia of the Pittosporaceae, the symplicate is much longer than the synascidiate zone, and the ovules are arranged along the first. Members of the latter family consequently have unilocular ovaries with a single cavity between adjacent carpels. == References == ### Answer: <Angiosperm orders>, <Apiales>

### Instruction: retrieve labels for this: Asteroids are minor planets, especially those of the inner Solar System. The larger ones have also been called planetoids. These terms have historically been applied to any astronomical object orbiting the Sun that did not show the disc of a planet and was not observed to have the characteristics of an active comet. As minor planets in the outer Solar System were discovered and found to have volatile-based surfaces that resemble those of comets, they were often distinguished from asteroids of the asteroid belt. In this article, the term "asteroid" refers to the minor planets of the inner Solar System including those co-orbital with Jupiter. There are millions of asteroids, many thought to be the shattered remnants of planetesimals, bodies within the young Sun's solar nebula that never grew large enough to become planets. The large majority of known asteroids orbit in the asteroid belt between the orbits of Mars and Jupiter, or are co-orbital with Jupiter (the Jupiter trojans). However, other orbital families exist with significant populations, including the near-Earth objects. Individual asteroids are classified by their characteristic spectra, with the majority falling into three main groups: C-type, M-type, and S-type. These were named after and are generally identified with carbon-rich, metallic, and silicate (stony) compositions, respectively. The size of asteroids varies greatly; the largest is almost 1,000 km (625 mi) across. Asteroids are differentiated from comets and meteoroids. In the case of comets, the difference is one of composition: while asteroids are mainly composed of mineral and rock, comets are composed of dust and ice. In addition, asteroids formed closer to the sun, preventing the development of the aforementioned cometary ice. The difference between asteroids and meteoroids is mainly one of size: meteoroids have a diameter of less than one meter, whereas asteroids have a diameter of greater than one meter. Finally, meteoroids can be composed of either cometary or asteroidal materials.Only one asteroid, 4 Vesta, which has a relatively reflective surface, is normally visible to the naked eye, and this only in very dark skies when it is favorably positioned. Rarely, small asteroids passing close to Earth may be visible to the naked eye for a short time. As of October 2017, the Minor Planet Center had data on almost 745,000 objects in the inner and outer Solar System, of which almost 504,000 had enough information to be given numbered designations.The United Nations declared 30 June 2018 as International Asteroid Day to educate the public about asteroids. The date of International Asteroid Day commemorates the anniversary of the Tunguska asteroid impact over Siberia, Russian Federation, on 30 June 1908.In April 2018, the B612 Foundation reported "It's a 100 per cent certain we'll be hit [by a devastating asteroid], but we're not 100 per cent sure when." == Discovery == The first asteroid to be discovered, Ceres, was originally considered to be a new planet. This was followed by the discovery of other similar bodies, which, with the equipment of the time, appeared to be points of light, like stars, showing little or no planetary disc, though readily distinguishable from stars due to their apparent motions. This prompted the astronomer Sir William Herschel to propose the term "asteroid", coined in Greek as ἀστεροειδής, or asteroeidēs, meaning 'star-like, star-shaped', and derived from the Ancient Greek ἀστήρ astēr 'star, planet'. In the early second half of the nineteenth century, the terms "asteroid" and "planet" (not always qualified as "minor") were still used interchangeably. === Historical methods === Asteroid discovery methods have dramatically improved over the past two centuries. In the last years of the 18th century, Baron Franz Xaver von Zach organized a group of 24 astronomers to search the sky for the missing planet predicted at about 2.8 AU from the Sun by the Titius-Bode law, partly because of the discovery, by Sir William Herschel in 1781, of the planet Uranus at the distance predicted by the law. This task required that hand-drawn sky charts be prepared for all stars in the zodiacal band down to an agreed-upon limit of faintness. On subsequent nights, the sky would be charted again and any moving object would, hopefully, be spotted. The expected motion of the missing planet was about 30 seconds of arc per hour, readily discernible by observers. The first object, Ceres, was not discovered by a member of the group, but rather by accident in 1801 by Giuseppe Piazzi, director of the observatory of Palermo in Sicily. He discovered a new star-like object in Taurus and followed the displacement of this object during several nights. Later that year, Carl Friedrich Gauss used these observations to calculate the orbit of this unknown object, which was found to be between the planets Mars and Jupiter. Piazzi named it after Ceres, the Roman goddess of agriculture. Three other asteroids (2 Pallas, 3 Juno, and 4 Vesta) were discovered over the next few years, with Vesta found in 1807. After eight more years of fruitless searches, most astronomers assumed that there were no more and abandoned any further searches.However, Karl Ludwig Hencke persisted, and began searching for more asteroids in 1830. Fifteen years later, he found 5 Astraea, the first new asteroid in 38 years. He also found 6 Hebe less than two years later. After this, other astronomers joined in the search and at least one new asteroid was discovered every year after that (except the wartime years 1944 and 1945). Notable asteroid hunters of this early era were J. R. Hind, Annibale de Gasparis, Robert Luther, H. M. S. Goldschmidt, Jean Chacornac, James Ferguson, Norman Robert Pogson, E. W. Tempel, J. C. Watson, C. H. F. Peters, A. Borrelly, J. Palisa, the Henry brothers and Auguste Charlois. In 1891, Max Wolf pioneered the use of astrophotography to detect asteroids, which appeared as short streaks on long-exposure photographic plates. This dramatically increased the rate of detection compared with earlier visual methods: Wolf alone discovered 248 asteroids, beginning with 323 Brucia, whereas only slightly more than 300 had been discovered up to that point. It was known that there were many more, but most astronomers did not bother with them, calling them "vermin of the skies", a phrase variously attributed to Eduard Suess and Edmund Weiss. Even a century later, only a few thousand asteroids were identified, numbered and named. === Manual methods of the 1900s and modern reporting === Until 1998, asteroids were discovered by a four-step process. First, a region of the sky was photographed by a wide-field telescope, or astrograph. Pairs of photographs were taken, typically one hour apart. Multiple pairs could be taken over a series of days. Second, the two films or plates of the same region were viewed under a stereoscope. Any body in orbit around the Sun would move slightly between the pair of films. Under the stereoscope, the image of the body would seem to float slightly above the background of stars. Third, once a moving body was identified, its location would be measured precisely using a digitizing microscope. The location would be measured relative to known star locations.These first three steps do not constitute asteroid discovery: the observer has only found an apparition, which gets a provisional designation, made up of the year of discovery, a letter representing the half-month of discovery, and finally a letter and a number indicating the discovery's sequential number (example: 1998 FJ74). The last step of discovery is to send the locations and time of observations to the Minor Planet Center, where computer programs determine whether an apparition ties together earlier apparitions into a single orbit. If so, the object receives a catalogue number and the observer of the first apparition with a calculated orbit is declared the discoverer, and granted the honor of naming the object subject to the approval of the International Astronomical Union. === Computerized methods === There is increasing interest in identifying asteroids whose orbits cross Earth's, and that could, given enough time, collide with Earth (see Earth-crosser asteroids). The three most important groups of near-Earth asteroids are the Apollos, Amors, and Atens. Various asteroid deflection strategies have been proposed, as early as the 1960s. The near-Earth asteroid 433 Eros had been discovered as long ago as 1898, and the 1930s brought a flurry of similar objects. In order of discovery, these were: 1221 Amor, 1862 Apollo, 2101 Adonis, and finally 69230 Hermes, which approached within 0.005 AU of Earth in 1937. Astronomers began to realize the possibilities of Earth impact. Two events in later decades increased the alarm: the increasing acceptance of the Alvarez hypothesis that an impact event resulted in the Cretaceous–Paleogene extinction, and the 1994 observation of Comet Shoemaker-Levy 9 crashing into Jupiter. The U.S. military also declassified the information that its military satellites, built to detect nuclear explosions, had detected hundreds of upper-atmosphere impacts by objects ranging from one to ten meters across. All these considerations helped spur the launch of highly efficient surveys that consist of charge-coupled device (CCD) cameras and computers directly connected to telescopes. As of 2011, it was estimated that 89% to 96% of near-Earth asteroids one kilometer or larger in diameter had been discovered. A list of teams using such systems includes: Lincoln Near-Earth Asteroid Research (LINEAR) Near-Earth Asteroid Tracking (NEAT) Spacewatch Lowell Observatory Near-Earth-Object Search (LONEOS) Catalina Sky Survey (CSS) Campo Imperatore Near-Earth Object Survey (CINEOS) Japanese Spaceguard Association Asiago-DLR Asteroid Survey (ADAS) Pan-STARRSAs of 20 September 2013, the LINEAR system alone has discovered 138,393 asteroids. Among all the surveys, 4711 near-Earth asteroids have been discovered including over 600 more than 1 km (0.6 mi) in diameter. == Terminology == Traditionally, small bodies orbiting the Sun were classified as comets, asteroids, or meteoroids, with anything smaller than ten meters across being called a meteoroid. Beech and Steel's 1995 paper proposed a meteoroid definition including size limits. The term "asteroid", from the Greek word for "star-like", never had a formal definition, with the broader term minor planet being preferred by the International Astronomical Union. However, following the discovery of asteroids below ten meters in size, Rubin and Grossman's 2010 paper revised the previous definition of meteoroid to objects between 10 µm and 1 meter in size in order to maintain the distinction between asteroids and meteoroids. The smallest asteroids discovered (based on absolute magnitude H) are 2008 TS26 with H = 33.2 and 2011 CQ1 with H = 32.1 both with an estimated size of about 1 meter.In 2006, the term "small Solar System body" was also introduced to cover both most minor planets and comets. Other languages prefer "planetoid" (Greek for "planet-like"), and this term is occasionally used in English especially for larger minor planets such as the dwarf planets as well as an alternative for asteroids since they are not star-like. The word "planetesimal" has a similar meaning, but refers specifically to the small building blocks of the planets that existed when the Solar System was forming. The term "planetule" was coined by the geologist William Daniel Conybeare to describe minor planets, but is not in common use. The three largest objects in the asteroid belt, Ceres, Pallas, and Vesta, grew to the stage of protoplanets. Ceres is a dwarf planet, the only one in the inner Solar System. When found, asteroids were seen as a class of objects distinct from comets, and there was no unified term for the two until "small Solar System body" was coined in 2006. The main difference between an asteroid and a comet is that a comet shows a coma due to sublimation of near surface ices by solar radiation. A few objects have ended up being dual-listed because they were first classified as minor planets but later showed evidence of cometary activity. Conversely, some (perhaps all) comets are eventually depleted of their surface volatile ices and become asteroid-like. A further distinction is that comets typically have more eccentric orbits than most asteroids; most "asteroids" with notably eccentric orbits are probably dormant or extinct comets.For almost two centuries, from the discovery of Ceres in 1801 until the discovery of the first centaur, Chiron in 1977, all known asteroids spent most of their time at or within the orbit of Jupiter, though a few such as Hidalgo ventured far beyond Jupiter for part of their orbit. Those located between the orbits of Mars and Jupiter were known for many years simply as The Asteroids. When astronomers started finding more small bodies that permanently resided further out than Jupiter, now called centaurs, they numbered them among the traditional asteroids, though there was debate over whether they should be considered asteroids or as a new type of object. Then, when the first trans-Neptunian object (other than Pluto), Albion, was discovered in 1992, and especially when large numbers of similar objects started turning up, new terms were invented to sidestep the issue: Kuiper-belt object, trans-Neptunian object, scattered-disc object, and so on. These inhabit the cold outer reaches of the Solar System where ices remain solid and comet-like bodies are not expected to exhibit much cometary activity; if centaurs or trans-Neptunian objects were to venture close to the Sun, their volatile ices would sublimate, and traditional approaches would classify them as comets and not asteroids. The innermost of these are the Kuiper-belt objects, called "objects" partly to avoid the need to classify them as asteroids or comets. They are thought to be predominantly comet-like in composition, though some may be more akin to asteroids. Furthermore, most do not have the highly eccentric orbits associated with comets, and the ones so far discovered are larger than traditional comet nuclei. (The much more distant Oort cloud is hypothesized to be the main reservoir of dormant comets.) Other recent observations, such as the analysis of the cometary dust collected by the Stardust probe, are increasingly blurring the distinction between comets and asteroids, suggesting "a continuum between asteroids and comets" rather than a sharp dividing line.The minor planets beyond Jupiter's orbit are sometimes also called "asteroids", especially in popular presentations. However, it is becoming increasingly common for the term "asteroid" to be restricted to minor planets of the inner Solar System. Therefore, this article will restrict itself for the most part to the classical asteroids: objects of the asteroid belt, Jupiter trojans, and near-Earth objects. When the IAU introduced the class small Solar System bodies in 2006 to include most objects previously classified as minor planets and comets, they created the class of dwarf planets for the largest minor planets—those that have enough mass to have become ellipsoidal under their own gravity. According to the IAU, "the term 'minor planet' may still be used, but generally the term 'Small Solar System Body' will be preferred." Currently only the largest object in the asteroid belt, Ceres, at about 975 km (606 mi) across, has been placed in the dwarf planet category. == Formation == It is thought that planetesimals in the asteroid belt evolved much like the rest of the solar nebula until Jupiter neared its current mass, at which point excitation from orbital resonances with Jupiter ejected over 99% of planetesimals in the belt. Simulations and a discontinuity in spin rate and spectral properties suggest that asteroids larger than approximately 120 km (75 mi) in diameter accreted during that early era, whereas smaller bodies are fragments from collisions between asteroids during or after the Jovian disruption. Ceres and Vesta grew large enough to melt and differentiate, with heavy metallic elements sinking to the core, leaving rocky minerals in the crust.In the Nice model, many Kuiper-belt objects are captured in the outer asteroid belt, at distances greater than 2.6 AU. Most were later ejected by Jupiter, but those that remained may be the D-type asteroids, and possibly include Ceres. == Distribution within the Solar System == Various dynamical groups of asteroids have been discovered orbiting in the inner Solar System. Their orbits are perturbed by the gravity of other bodies in the Solar System and by the Yarkovsky effect. Significant populations include: === Asteroid belt === The majority of known asteroids orbit within the asteroid belt between the orbits of Mars and Jupiter, generally in relatively low-eccentricity (i.e. not very elongated) orbits. This belt is now estimated to contain between 1.1 and 1.9 million asteroids larger than 1 km (0.6 mi) in diameter, and millions of smaller ones. These asteroids may be remnants of the protoplanetary disk, and in this region the accretion of planetesimals into planets during the formative period of the Solar System was prevented by large gravitational perturbations by Jupiter. === Trojans === Trojans are populations that share an orbit with a larger planet or moon, but do not collide with it because they orbit in one of the two Lagrangian points of stability, L4 and L5, which lie 60° ahead of and behind the larger body. The most significant population of trojans are the Jupiter trojans. Although fewer Jupiter trojans have been discovered (As of 2010), it is thought that they are as numerous as the asteroids in the asteroid belt. Trojans have been found in the orbits of other planets, including Venus, Earth, Mars, Uranus, and Neptune. === Near-Earth asteroids === Near-Earth asteroids, or NEAs, are asteroids that have orbits that pass close to that of Earth. Asteroids that actually cross Earth's orbital path are known as Earth-crossers. As of June 2016, 14,464 near-Earth asteroids are known and the number over one kilometer in diameter is estimated to be 900–1,000. == Characteristics == === Size distribution === Asteroids vary greatly in size, from almost 1000 km for the largest down to rocks just 1 meter across. The three largest are very much like miniature planets: they are roughly spherical, have at least partly differentiated interiors, and are thought to be surviving protoplanets. The vast majority, however, are much smaller and are irregularly shaped; they are thought to be either surviving planetesimals or fragments of larger bodies. The dwarf planet Ceres is by far the largest asteroid, with a diameter of 975 km (606 mi). The next largest are 4 Vesta and 2 Pallas, both with diameters of just over 500 km (300 mi). Vesta is the only main-belt asteroid that can, on occasion, be visible to the naked eye. On some rare occasions, a near-Earth asteroid may briefly become visible without technical aid; see 99942 Apophis. The mass of all the objects of the asteroid belt, lying between the orbits of Mars and Jupiter, is estimated to be about 2.8–3.2×1021 kg, or about 4% of the mass of the Moon. Of this, Ceres comprises 0.95×1021 kg, a third of the total. Adding in the next three most massive objects, Vesta (9%), Pallas (7%), and Hygiea (3%), brings this figure up to 51%; whereas the three after that, 511 Davida (1.2%), 704 Interamnia (1.0%), and 52 Europa (0.9%), only add another 3% to the total mass. The number of asteroids then increases rapidly as their individual masses decrease. The number of asteroids decreases markedly with size. Although this generally follows a power law, there are 'bumps' at 5 km and 100 km, where more asteroids than expected from a logarithmic distribution are found. ==== Largest asteroids ==== Although their location in the asteroid belt excludes them from planet status, the three largest objects, Ceres, Vesta, and Pallas, are intact protoplanets that share many characteristics common to planets, and are atypical compared to the majority of "potato"-shaped asteroids. The fourth largest asteroid, Hygiea, has an undifferentiated interior, like the majority of asteroids. Between them, the four largest asteroids constitute half the mass of the asteroid belt. Ceres is the only asteroid with a fully ellipsoidal shape and hence the only one that is a dwarf planet. It has a much higher absolute magnitude than the other asteroids, of around 3.32, and may possess a surface layer of ice. Like the planets, Ceres is differentiated: it has a crust, a mantle and a core. No meteorites from Ceres have been found on Earth. Vesta, too, has a differentiated interior, though it formed inside the Solar System's frost line, and so is devoid of water; its composition is mainly of basaltic rock such as olivine. Aside from the large crater at its southern pole, Rheasilvia, Vesta also has an ellipsoidal shape. Vesta is the parent body of the Vestian family and other V-type asteroids, and is the source of the HED meteorites, which constitute 5% of all meteorites on Earth. Pallas is unusual in that, like Uranus, it rotates on its side, with its axis of rotation tilted at high angles to its orbital plane. Its composition is similar to that of Ceres: high in carbon and silicon, and perhaps partially differentiated. Pallas is the parent body of the Palladian family of asteroids. Hygiea is the largest carbonaceous asteroid and, unlike the other largest asteroids, lies relatively close to the plane of the ecliptic. It is the largest member and presumed parent body of the Hygiean family of asteroids. === Rotation === Measurements of the rotation rates of large asteroids in the asteroid belt show that there is an upper limit. No asteroid with a diameter larger than 100 meters has a rotation period smaller than 2.2 hours. For asteroids rotating faster than approximately this rate, the inertial force at the surface is greater than the gravitational force, so any loose surface material would be flung out. However, a solid object should be able to rotate much more rapidly. This suggests that most asteroids with a diameter over 100 meters are rubble piles formed through accumulation of debris after collisions between asteroids. === Composition === The physical composition of asteroids is varied and in most cases poorly understood. Ceres appears to be composed of a rocky core covered by an icy mantle, where Vesta is thought to have a nickel-iron core, olivine mantle, and basaltic crust. 10 Hygiea, however, which appears to have a uniformly primitive composition of carbonaceous chondrite, is thought to be the largest undifferentiated asteroid. Most of the smaller asteroids are thought to be piles of rubble held together loosely by gravity, though the largest are probably solid. Some asteroids have moons or are co-orbiting binaries: Rubble piles, moons, binaries, and scattered asteroid families are thought to be the results of collisions that disrupted a parent asteroid, or, possibly, a planet.Asteroids contain traces of amino acids and other organic compounds, and some speculate that asteroid impacts may have seeded the early Earth with the chemicals necessary to initiate life, or may have even brought life itself to Earth (also see panspermia). In August 2011, a report, based on NASA studies with meteorites found on Earth, was published suggesting DNA and RNA components (adenine, guanine and related organic molecules) may have been formed on asteroids and comets in outer space. Composition is calculated from three primary sources: albedo, surface spectrum, and density. The last can only be determined accurately by observing the orbits of moons the asteroid might have. So far, every asteroid with moons has turned out to be a rubble pile, a loose conglomeration of rock and metal that may be half empty space by volume. The investigated asteroids are as large as 280 km in diameter, and include 121 Hermione (268×186×183 km), and 87 Sylvia (384×262×232 km). Only half a dozen asteroids are larger than 87 Sylvia, though none of them have moons; however, some smaller asteroids are thought to be more massive, suggesting they may not have been disrupted, and indeed 511 Davida, the same size as Sylvia to within measurement error, is estimated to be two and a half times as massive, though this is highly uncertain. The fact that such large asteroids as Sylvia can be rubble piles, presumably due to disruptive impacts, has important consequences for the formation of the Solar System: Computer simulations of collisions involving solid bodies show them destroying each other as often as merging, but colliding rubble piles are more likely to merge. This means that the cores of the planets could have formed relatively quickly.On 7 October 2009, the presence of water ice was confirmed on the surface of 24 Themis using NASA’s Infrared Telescope Facility. The surface of the asteroid appears completely covered in ice. As this ice layer is sublimated, it may be getting replenished by a reservoir of ice under the surface. Organic compounds were also detected on the surface. Scientists hypothesize that some of the first water brought to Earth was delivered by asteroid impacts after the collision that produced the Moon. The presence of ice on 24 Themis supports this theory.In October 2013, water was detected on an extrasolar body for the first time, on an asteroid orbiting the white dwarf GD 61. On 22 January 2014, European Space Agency (ESA) scientists reported the detection, for the first definitive time, of water vapor on Ceres, the largest object in the asteroid belt. The detection was made by using the far-infrared abilities of the Herschel Space Observatory. The finding is unexpected because comets, not asteroids, are typically considered to "sprout jets and plumes". According to one of the scientists, "The lines are becoming more and more blurred between comets and asteroids." In May 2016, significant asteroid data arising from the Wide-field Infrared Survey Explorer and NEOWISE missions have been questioned. Although the early original criticism had not undergone peer review, a more recent peer-reviewed study was subsequently published. === Surface features === Most asteroids outside the "big four" (Ceres, Pallas, Vesta, and Hygiea) are likely to be broadly similar in appearance, if irregular in shape. 50-km (31-mi) 253 Mathilde is a rubble pile saturated with craters with diameters the size of the asteroid's radius, and Earth-based observations of 300-km (186-mi) 511 Davida, one of the largest asteroids after the big four, reveal a similarly angular profile, suggesting it is also saturated with radius-size craters. Medium-sized asteroids such as Mathilde and 243 Ida that have been observed up close also reveal a deep regolith covering the surface. Of the big four, Pallas and Hygiea are practically unknown. Vesta has compression fractures encircling a radius-size crater at its south pole but is otherwise a spheroid. Ceres seems quite different in the glimpses Hubble has provided, with surface features that are unlikely to be due to simple craters and impact basins, but details will be expanded with the Dawn spacecraft, which entered Ceres orbit on 6 March 2015. === Color === Asteroids become darker and redder with age due to space weathering. However evidence suggests most of the color change occurs rapidly, in the first hundred thousands years, limiting the usefulness of spectral measurement for determining the age of asteroids. == Classification == Asteroids are commonly classified according to two criteria: the characteristics of their orbits, and features of their reflectance spectrum. === Orbital classification === Many asteroids have been placed in groups and families based on their orbital characteristics. Apart from the broadest divisions, it is customary to name a group of asteroids after the first member of that group to be discovered. Groups are relatively loose dynamical associations, whereas families are tighter and result from the catastrophic break-up of a large parent asteroid sometime in the past. Families are more common and easier to identify within the main asteroid belt, but several small families have been reported among the Jupiter trojans. Main belt families were first recognized by Kiyotsugu Hirayama in 1918 and are often called Hirayama families in his honor. About 30–35% of the bodies in the asteroid belt belong to dynamical families each thought to have a common origin in a past collision between asteroids. A family has also been associated with the plutoid dwarf planet Haumea. ==== Quasi-satellites and horseshoe objects ==== Some asteroids have unusual horseshoe orbits that are co-orbital with Earth or some other planet. Examples are 3753 Cruithne and 2002 AA29. The first instance of this type of orbital arrangement was discovered between Saturn's moons Epimetheus and Janus. Sometimes these horseshoe objects temporarily become quasi-satellites for a few decades or a few hundred years, before returning to their earlier status. Both Earth and Venus are known to have quasi-satellites. Such objects, if associated with Earth or Venus or even hypothetically Mercury, are a special class of Aten asteroids. However, such objects could be associated with outer planets as well. === Spectral classification === In 1975, an asteroid taxonomic system based on color, albedo, and spectral shape was developed by Clark R. Chapman, David Morrison, and Ben Zellner. These properties are thought to correspond to the composition of the asteroid's surface material. The original classification system had three categories: C-types for dark carbonaceous objects (75% of known asteroids), S-types for stony (silicaceous) objects (17% of known asteroids) and U for those that did not fit into either C or S. This classification has since been expanded to include many other asteroid types. The number of types continues to grow as more asteroids are studied. The two most widely used taxonomies now used are the Tholen classification and SMASS classification. The former was proposed in 1984 by David J. Tholen, and was based on data collected from an eight-color asteroid survey performed in the 1980s. This resulted in 14 asteroid categories. In 2002, the Small Main-Belt Asteroid Spectroscopic Survey resulted in a modified version of the Tholen taxonomy with 24 different types. Both systems have three broad categories of C, S, and X asteroids, where X consists of mostly metallic asteroids, such as the M-type. There are also several smaller classes.The proportion of known asteroids falling into the various spectral types does not necessarily reflect the proportion of all asteroids that are of that type; some types are easier to detect than others, biasing the totals. ==== Problems ==== Originally, spectral designations were based on inferences of an asteroid's composition. However, the correspondence between spectral class and composition is not always very good, and a variety of classifications are in use. This has led to significant confusion. Although asteroids of different spectral classifications are likely to be composed of different materials, there are no assurances that asteroids within the same taxonomic class are composed of similar materials. == Naming == A newly discovered asteroid is given a provisional designation (such as 2002 AT4) consisting of the year of discovery and an alphanumeric code indicating the half-month of discovery and the sequence within that half-month. Once an asteroid's orbit has been confirmed, it is given a number, and later may also be given a name (e.g. 433 Eros). The formal naming convention uses parentheses around the number (e.g. (433) Eros), but dropping the parentheses is quite common. Informally, it is common to drop the number altogether, or to drop it after the first mention when a name is repeated in running text. In addition, names can be proposed by the asteroid's discoverer, within guidelines established by the International Astronomical Union. === Symbols === The first asteroids to be discovered were assigned iconic symbols like the ones traditionally used to designate the planets. By 1855 there were two dozen asteroid symbols, which often occurred in multiple variants. In 1851, after the fifteenth asteroid (Eunomia) had been discovered, Johann Franz Encke made a major change in the upcoming 1854 edition of the Berliner Astronomisches Jahrbuch (BAJ, Berlin Astronomical Yearbook). He introduced a disk (circle), a traditional symbol for a star, as the generic symbol for an asteroid. The circle was then numbered in order of discovery to indicate a specific asteroid (although he assigned ① to the fifth, Astraea, while continuing to designate the first four only with their existing iconic symbols). The numbered-circle convention was quickly adopted by astronomers, and the next asteroid to be discovered (16 Psyche, in 1852) was the first to be designated in that way at the time of its discovery. However, Psyche was given an iconic symbol as well, as were a few other asteroids discovered over the next few years (see chart above). 20 Massalia was the first asteroid that was not assigned an iconic symbol, and no iconic symbols were created after the 1855 discovery of 37 Fides. That year Astraea's number was increased to ⑤, but the first four asteroids, Ceres to Vesta, were not listed by their numbers until the 1867 edition. The circle was soon abbreviated to a pair of parentheses, which were easier to typeset and sometimes omitted altogether over the next few decades, leading to the modern convention. == Exploration == Until the age of space travel, objects in the asteroid belt were merely pinpricks of light in even the largest telescopes and their shapes and terrain remained a mystery. The best modern ground-based telescopes and the Earth-orbiting Hubble Space Telescope can resolve a small amount of detail on the surfaces of the largest asteroids, but even these mostly remain little more than fuzzy blobs. Limited information about the shapes and compositions of asteroids can be inferred from their light curves (their variation in brightness as they rotate) and their spectral properties, and asteroid sizes can be estimated by timing the lengths of star occulations (when an asteroid passes directly in front of a star). Radar imaging can yield good information about asteroid shapes and orbital and rotational parameters, especially for near-Earth asteroids. In terms of delta-v and propellant requirements, NEOs are more easily accessible than the Moon.The first close-up photographs of asteroid-like objects were taken in 1971, when the Mariner 9 probe imaged Phobos and Deimos, the two small moons of Mars, which are probably captured asteroids. These images revealed the irregular, potato-like shapes of most asteroids, as did later images from the Voyager probes of the small moons of the gas giants. The first true asteroid to be photographed in close-up was 951 Gaspra in 1991, followed in 1993 by 243 Ida and its moon Dactyl, all of which were imaged by the Galileo probe en route to Jupiter. The first dedicated asteroid probe was NEAR Shoemaker, which photographed 253 Mathilde in 1997, before entering into orbit around 433 Eros, finally landing on its surface in 2001. Other asteroids briefly visited by spacecraft en route to other destinations include 9969 Braille (by Deep Space 1 in 1999), and 5535 Annefrank (by Stardust in 2002). From September to November 2005, the Japanese Hayabusa probe studied 25143 Itokawa in detail and was plagued with difficulties, but returned samples of its surface to Earth on 13 June 2010. The European Rosetta probe (launched in 2004) flew by 2867 Šteins in 2008 and 21 Lutetia, the third-largest asteroid visited to date, in 2010. In September 2007, NASA launched the Dawn spacecraft, which orbited 4 Vesta from July 2011 to September 2012, and has been orbiting the dwarf planet 1 Ceres since 2015. 4 Vesta is the second-largest asteroid visited to date. On 13 December 2012, China's lunar orbiter Chang'e 2 flew within 3.2 km (2 mi) of the asteroid 4179 Toutatis on an extended mission. The Japan Aerospace Exploration Agency (JAXA) launched the Hayabusa2 probe in December 2014, and plans to return samples from 162173 Ryugu in December 2020. In June 2018, the US National Science and Technology Council warned that America is unprepared for an asteroid impact event, and has developed and released the "National Near-Earth Object Preparedness Strategy Action Plan" to better prepare. === Planned and future missions === In May 2011, NASA selected the OSIRIS-REx sample return mission to asteroid 101955 Bennu; it launched on September 8, 2016. In early 2013, NASA announced the planning stages of a mission to capture a near-Earth asteroid and move it into lunar orbit where it could possibly be visited by astronauts and later impacted into the Moon. On 19 June 2014, NASA reported that asteroid 2011 MD was a prime candidate for capture by a robotic mission, perhaps in the early 2020s.It has been suggested that asteroids might be used as a source of materials that may be rare or exhausted on Earth (asteroid mining), or materials for constructing space habitats (see Colonization of the asteroids). Materials that are heavy and expensive to launch from Earth may someday be mined from asteroids and used for space manufacturing and construction. In the U.S. Discovery program the Psyche spacecraft proposal to 16 Psyche and Lucy spacecraft to Jupiter trojans made it to the semifinalist stage of mission selection. == Fiction == Asteroids and the asteroid belt are a staple of science fiction stories. Asteroids play several potential roles in science fiction: as places human beings might colonize, resources for extracting minerals, hazards encountered by spacecraft traveling between two other points, and as a threat to life on Earth or other inhabited planets, dwarf planets and natural satellites by potential impact. == Gallery == == See also == == Notes == == References == == External links == Alphabetical list of minor planet names (ASCII) (Minor Planet Center) Asteroid articles in Planetary Science Research Discoveries ESA Space Situational Awareness: Near-Earth Object Segment IAU Committee on Small Body Nomenclature JPL Asteroid Watch Site NASA Asteroid and Comet Watch Site Near Earth Asteroid Tracking (NEAT) Near Earth Objects Dynamic Site NEO MAP (Armagh Observatory) Spaceguard Centre TECA Table of next close approaches to the Earth When Did the Asteroids Become Minor Planets?

### Instruction: retrieve labels for this: An allocution, or allocutus, is a formal statement made to the court by the defendant who has been found guilty prior to being sentenced. It is part of the criminal procedure in some jurisdictions using common law. == Concept == An allocution allows the defendant to explain why the sentence should be lenient. In plea bargains, an allocution may be required of the defendant. The defendant explicitly admits specifically and in detail the actions and their reasons in exchange for a reduced sentence. In principle, that removes any doubt as to the exact nature of the defendant's guilt in the matter. The term "allocution" is used generally only in jurisdictions in the United States, but there are vaguely similar processes in other common law countries. In many other jurisdictions, it is for the defense lawyer to mitigate on his client's behalf, and the defendant rarely has the opportunity to speak. The right of victims to speak at sentencing is also sometimes referred to as allocution. == Australia == In Australia, the term allocutus is used by the Clerk of Arraigns or another formal associate of the Court. It is generally phrased as, "Prisoner at the Bar, you have been found Guilty by a jury of your peers of the offense of XYZ. Do you have anything to say as to why the sentence of this Court should not now be passed upon you?" The defense counsel will then make a plea in mitigation (also called submissions on penalty) in an attempt to mitigate the relative seriousness of the offense and heavily refer to and rely upon the defendant's previous good character and good works, if any. The right to make a plea in mitigation is absolute. If a judge or magistrate refused to hear such a plea or obviously did not properly consider it, the sentence could be overturned on appeal. == United States == In most of the United States, defendants are allowed the opportunity to allocute before a sentence is passed. Some jurisdictions hold that as an absolute right. In its absence, a sentence but not the conviction may be overturned, resulting in the need for a new sentencing hearing. In the federal system, Federal Rule of Criminal Procedure 32(i)(4) provides that the court must "address the defendant personally in order to permit the defendant to speak or present any information to mitigate the sentence."The Federal Public Defender recommends that defendants speak in terms of how a lenient sentence will be sufficient but not greater than necessary to comply with the statutory directives set forth in 18 U.S.C. § 3553(a). == See also == Confession (law) == References == ### Answer: <Criminal procedure>, <Evidence law>

### Instruction: retrieve labels for this: Anime () (Japanese: アニメ, [aɲime] ( listen), plural: anime) is a style of hand-drawn and computer animation originating in, and commonly associated with, Japan. The word anime is the Japanese term for animation, which means all forms of animated media. Outside Japan, anime refers specifically to animation from Japan or as a Japanese-disseminated animation style often characterized by colorful graphics, vibrant characters and fantastical themes. The culturally abstract approach to the word's meaning may open up the possibility of anime produced in countries other than Japan. For simplicity, many Westerners strictly view anime as a Japanese animation product. Some scholars suggest defining anime as specifically or quintessentially Japanese may be related to a new form of Orientalism.The earliest commercial Japanese animation dates to 1917, and Japanese anime production has since continued to increase steadily. The characteristic anime art style emerged in the 1960s with the works of Osamu Tezuka and spread internationally in the late twentieth century, developing a large domestic and international audience. Anime is distributed theatrically, by way of television broadcasts, directly to home media, and over the Internet. It is classified into numerous genres targeting diverse broad and niche audiences. Anime is a diverse art form with distinctive production methods and techniques that have been adapted over time in response to emergent technologies. It consists of an ideal story-telling mechanism, combining graphic art, characterization, cinematography, and other forms of imaginative and individualistic techniques. The production of anime focuses less on the animation of movement and more on the realism of settings as well as the use of camera effects, including panning, zooming, and angle shots. Being hand-drawn, anime is separated from reality by a crucial gap of fiction that provides an ideal path for escapism that audiences can immerse themselves into with relative ease. Diverse art styles are used and character proportions and features can be quite varied, including characteristically large emotive or realistically sized eyes. The anime industry consists of over 430 production studios, including major names like Studio Ghibli, Gainax, and Toei Animation. Despite comprising only a fraction of Japan's domestic film market, anime makes up a majority of Japanese DVD sales. It has also seen international success after the rise of English-dubbed programming. This rise in international popularity has resulted in non-Japanese productions using the anime art style. Whether these works are anime-influenced animation or proper anime is a subject for debate amongst fans. == Definition and usage == Anime is an art form, specifically animation, that includes all genres found in cinema, but it can be mistakenly classified as a genre. In Japanese, the term anime refers to all forms of animation from around the world. In English, anime () is more restrictively used to denote a "Japanese-style animated film or television entertainment" or as "a style of animation created in Japan".The etymology of the word anime is disputed. The English term "animation" is written in Japanese katakana as アニメーション (animēshon, pronounced [animeːɕoɴ]) and is アニメ (anime) in its shortened form. Some sources claim that anime derives from the French term for animation dessin animé, but others believe this to be a myth derived from the French popularity of the medium in the late 1970s and 1980s. In English, anime—when used as a common noun—normally functions as a mass noun. (For example: "Do you watch anime?" or "How much anime have you collected?") Prior to the widespread use of anime, the term Japanimation was prevalent throughout the 1970s and 1980s. In the mid-1980s, the term anime began to supplant Japanimation. In general, the latter term now only appears in period works where it is used to distinguish and identify Japanese animation.The word anime has also been criticised, e.g. in 1987, when Hayao Miyazaki stated that he despised the truncated word anime because to him it represented the desolation of the Japanese animation industry. He equated the desolation with animators lacking motivation and with mass-produced, overly expressionistic products relying upon a fixed iconography of facial expressions and protracted and exaggerated action scenes but lacking depth and sophistication in that they do not attempt to convey emotion or thought. == Format == The first format of anime was theatrical viewing which originally began with commercial productions in 1917. Originally the animated flips were crude and required played musical components before adding sound and vocal components to the production. On July 14, 1958, Nippon Television aired Mogura no Abanchūru ("Mole's Adventure"), both the first televised and first color anime to debut. It wasn't until the 1960s when the first televised series were broadcast and it has remained a popular medium since. Works released in a direct to video format are called "original video animation" (OVA) or "original animation video" (OAV); and are typically not released theatrically or televised prior to home media release. The emergence of the Internet has led some animators to distribute works online in a format called "original net anime" (ONA).The home distribution of anime releases were popularized in the 1980s with the VHS and LaserDisc formats. The VHS NTSC video format used in both Japan and the United States is credited as aiding the rising popularity of anime in the 1990s. The Laser Disc and VHS formats were transcended by the DVD format which offered the unique advantages; including multiple subtitling and dubbing tracks on the same disc. The DVD format also has its drawbacks in the its usage of region coding; adopted by the industry to solve licensing, piracy and export problems and restricted region indicated on the DVD player. The Video CD (VCD) format was popular in Hong Kong and Taiwan, but became only a minor format in the United States that was closely associated with bootleg copies. == History == Japanese animation began in the early 20th century, when Japanese filmmakers experimented with the animation techniques also pioneered in France, Germany, the United States and Russia. A claim for the earliest Japanese animation is Katsudō Shashin, an undated and private work by an unknown creator. In 1917, the first professional and publicly displayed works began to appear. Animators such as Ōten Shimokawa and Seitarou Kitayama produced numerous works, with the oldest surviving film being Kouchi's Namakura Gatana, a two-minute clip of a samurai trying to test a new sword on his target only to suffer defeat. The 1923 Great Kantō earthquake resulted in widespread destruction to Japan's infrastructure and the destruction of Shimokawa's warehouse, destroying most of these early works.By the 1930s animation was well established in Japan as an alternative format to the live-action industry. It suffered competition from foreign producers and many animators, Noburō Ōfuji and Yasuji Murata, who still worked in cheaper cutout animation rather than cel animation. Other creators, Kenzō Masaoka and Mitsuyo Seo, nonetheless made great strides in animation technique; they benefited from the patronage of the government, which employed animators to produce educational shorts and propaganda. The first talkie anime was Chikara to Onna no Yo no Naka, produced by Masaoka in 1933. By 1940, numerous anime artists' organizations had risen, including the Shin Mangaha Shudan and Shin Nippon Mangaka. The first feature-length animated film was Momotaro's Divine Sea Warriors directed by Seo in 1944 with sponsorship by the Imperial Japanese Navy. The success of The Walt Disney Company's 1937 feature film Snow White and the Seven Dwarfs profoundly influenced many Japanese animators. In the 1960s, manga artist and animator Osamu Tezuka adapted and simplified many Disney animation techniques to reduce costs and to limit the number of frames in productions. He intended this as a temporary measure to allow him to produce material on a tight schedule with inexperienced animation staff. Three Tales, aired in 1960, was the first anime shown on television. The first anime television series was Otogi Manga Calendar, aired from 1961 to 1964. The 1970s saw a surge of growth in the popularity of manga, Japanese comic books and graphic novels, many of which were later animated. The work of Osamu Tezuka drew particular attention: he has been called a "legend" and the "god of manga". His work—and that of other pioneers in the field—inspired characteristics and genres that remain fundamental elements of anime today. The giant robot genre (known as "mecha" outside Japan), for instance, took shape under Tezuka, developed into the Super Robot genre under Go Nagai and others, and was revolutionized at the end of the decade by Yoshiyuki Tomino who developed the Real Robot genre. Robot anime like the Gundam and The Super Dimension Fortress Macross series became instant classics in the 1980s, and the robot genre of anime is still one of the most common in Japan and worldwide today. In the 1980s, anime became more accepted in the mainstream in Japan (although less than manga), and experienced a boom in production. Following a few successful adaptations of anime in overseas markets in the 1980s, anime gained increased acceptance in those markets in the 1990s and even more at the turn of the 21st century. In 2002, Spirited Away, a Studio Ghibli production directed by Hayao Miyazaki won the Golden Bear at the Berlin International Film Festival and in 2003 at the 75th Academy Awards it won the Academy Award for Best Animated Feature. == Genres == Anime are often classified by target demographic, including childrens' (子供, kodomo), girls' (少女, shōjo), boys' (少年, shōnen) and a diverse range of genres targeting an adult audience. Shoujo and shounen anime sometimes contain elements popular with children of both sexes in an attempt to gain crossover appeal. Adult anime may feature a slower pace or greater plot complexity that younger audiences typically find unappealing, as well as adult themes and situations. A subset of adult anime works featuring pornographic elements are labeled "R18" in Japan, and are internationally known as hentai (originating from pervert (変態, hentai)). By contrast, some anime subgenres incorporate ecchi, sexual themes or undertones without depictions of sexual intercourse, as typified in the comedic or harem genres; due to its popularity among adolescent and adult anime enthusiasts, the inclusion of such elements is considered a form of fan service.Anime's genre classification is different from other types of animation and does not lend itself to simple identity. Gilles Poitras compared the labeling Gundam 0080 and its complex depiction of war as a "giant robot" anime akin to simply labeling War and Peace a "war novel". Science fiction is a major anime genre and includes important historical works like Tezuka's Astro Boy and Yokoyama's Tetsujin 28-go. A major subgenre of science fiction is mecha, with the Gundam metaseries being iconic. The diverse fantasy genre includes works based on Asian and Western traditions and folklore; examples include the Japanese feudal fairytale InuYasha, and the depiction of Scandinavian goddesses who move to Japan to maintain a computer called Yggdrasil in Ah! My Goddess. Genre crossing in anime is also prevalent, such as the blend of fantasy and comedy in Dragon Half, and the incorporation of slapstick humor in the crime anime Castle of Cagliostro. Other subgenres found in anime include magical girl, harem, sports, martial arts, literary adaptations, medievalism, and war.Genres have emerged that explore homosexual romances. While originally pornographic in terminology, yaoi (male homosexuality) and yuri (female homosexuality) are broad terms used internationally to describe any focus on the themes or development of romantic homosexual relationships. Prior to 2000, homosexual characters were typically used for comedic effect, but some works portrayed these characters seriously or sympathetically. == Attributes == Anime differs greatly from other forms of animation by its diverse art styles, methods of animation, its production, and its process. Visually, anime is a diverse art form that contains a wide variety of art styles, differing from one creator, artist, and studio. While no one art style predominates anime as a whole, they do share some similar attributes in terms of animation technique and character design. === Animation technique === Anime follows the typical production of animation, including storyboarding, voice acting, character design, and cel production (Shirobako, itself a series, highlights many of the aspects involved in anime production). Since the 1990s, animators have increasingly used computer animation to improve the efficiency of the production process. Artists like Noburō Ōfuji pioneered the earliest anime works, which were experimental and consisted of images drawn on blackboards, stop motion animation of paper cutouts, and silhouette animation. Cel animation grew in popularity until it came to dominate the medium. In the 21st century, the use of other animation techniques is mostly limited to independent short films, including the stop motion puppet animation work produced by Tadahito Mochinaga, Kihachirō Kawamoto and Tomoyasu Murata. Computers were integrated into the animation process in the 1990s, with works such as Ghost in the Shell and Princess Mononoke mixing cel animation with computer-generated images. Fuji Film, a major cel production company, announced it would stop cel production, producing an industry panic to procure cel imports and hastening the switch to digital processes.Prior to the digital era, anime was produced with traditional animation methods using a pose to pose approach. The majority of mainstream anime uses fewer expressive key frames and more in-between animation.Japanese animation studios were pioneers of many limited animation techniques, and have given anime a distinct set of conventions. Unlike Disney animation, where the emphasis is on the movement, anime emphasizes the art quality and let limited animation techniques make up for the lack of time spent on movement. Such techniques are often used not only to meet deadlines but also as artistic devices. Anime scenes place emphasis on achieving three-dimensional views, and backgrounds are instrumental in creating the atmosphere of the work. The backgrounds are not always invented and are occasionally based on real locations, as exemplified in Howl's Moving Castle and The Melancholy of Haruhi Suzumiya. Oppliger stated that anime is one of the rare mediums where putting together an all-star cast usually comes out looking "tremendously impressive".The cinematic effects of anime differentiates itself from the stage plays found in American animation. Anime is cinematically shot as if by camera, including panning, zooming, distance and angle shots to more complex dynamic shots that would be difficult to produce in reality. In anime, the animation is produced before the voice acting, contrary to American animation which does the voice acting first; this can cause lip sync errors in the Japanese version. === Characters === Body proportions of human anime characters tend to accurately reflect the proportions of the human body in reality. The height of the head is considered by the artist as the base unit of proportion. Head heights can vary, but most anime characters are about seven to eight heads tall. Anime artists occasionally make deliberate modifications to body proportions to produce super deformed characters that feature a disproportionately small body compared to the head; many super deformed characters are two to four heads tall. Some anime works like Crayon Shin-chan completely disregard these proportions, such that they resemble Western cartoons. A common anime character design convention is exaggerated eye size. The animation of characters with large eyes in anime can be traced back to Osamu Tezuka, who was deeply influenced by such early animation characters as Betty Boop, who was drawn with disproportionately large eyes. Tezuka is a central figure in anime and manga history, whose iconic art style and character designs allowed for the entire range of human emotions to be depicted solely through the eyes. The artist adds variable color shading to the eyes and particularly to the cornea to give them greater depth. Generally, a mixture of a light shade, the tone color, and a dark shade is used. Cultural anthropologist Matt Thorn argues that Japanese animators and audiences do not perceive such stylized eyes as inherently more or less foreign. However, not all anime have large eyes. For example, the works of Hayao Miyazaki are known for having realistically proportioned eyes, as well as realistic hair colors on their characters. Hair in anime is often unnaturally lively and colorful or uniquely styled. The movement of hair in anime is exaggerated and "hair action" is used to emphasize the action and emotions of characters for added visual effect. Poitras traces hairstyle color to cover illustrations on manga, where eye-catching artwork and colorful tones are attractive for children's manga. Despite being produced for a domestic market, anime features characters whose race or nationality is not always defined, and this is often a deliberate decision, such as in the Pokémon animated series.Anime and manga artists often draw from a common canon of iconic facial expression illustrations to denote particular moods and thoughts. These techniques are often different in form than their counterparts in Western animation, and they include a fixed iconography that is used as shorthand for certain emotions and moods. For example, a male character may develop a nosebleed when aroused. A variety of visual symbols are employed, including sweat drops to depict nervousness, visible blushing for embarrassment, or glowing eyes for an intense glare. === Music === The opening and credits sequences of most anime television episodes are accompanied by Japanese pop or rock songs, often by reputed bands. They may be written with the series in mind, but are also aimed at the general music market, and therefore often allude only vaguely or not at all to the themes or plot of the series. Pop and rock songs are also sometimes used as incidental music ("insert songs") in an episode, often to highlight particularly important scenes. == Industry == The animation industry consists of more than 430 production companies with some of the major studios including Toei Animation, Gainax, Madhouse, Gonzo, Sunrise, Bones, TMS Entertainment, Nippon Animation, P.A.Works, Studio Pierrot and Studio Ghibli. Many of the studios are organized into a trade association, The Association of Japanese Animations. There is also a labor union for workers in the industry, the Japanese Animation Creators Association. Studios will often work together to produce more complex and costly projects, as done with Studio Ghibli's Spirited Away. An anime episode can cost between US$100,000 and US$300,000 to produce. In 2001, animation accounted for 7% of the Japanese film market, above the 4.6% market share for live-action works. The popularity and success of anime is seen through the profitability of the DVD market, contributing nearly 70% of total sales. According to a 2016 article on Nikkei Asian Review, Japanese television stations have bought over ¥60 billion worth of anime from production companies "over the past few years", compared with under ¥20 billion from overseas. There has been a rise in sales of shows to television stations in Japan, caused by late night anime with adults as the target demographic. This type of anime is less popular outside Japan, being considered "more of a niche product". Spirited Away (2001) is the all-time highest-grossing film in Japan. It was also the highest-grossing anime film worldwide until it was overtaken by Makoto Shinkai's 2016 film Your Name. Anime films represent a large part of the highest-grossing Japanese films yearly in Japan, with 6 out of the top 10 in 2014, in 2015 and also in 2016. Anime has to be licensed by companies in other countries in order to be legally released. While anime has been licensed by its Japanese owners for use outside Japan since at least the 1960s, the practice became well-established in the United States in the late 1970s to early 1980s, when such TV series as Gatchaman and Captain Harlock were licensed from their Japanese parent companies for distribution in the US market. The trend towards American distribution of anime continued into the 1980s with the licensing of titles such as Voltron and the 'creation' of new series such as Robotech through use of source material from several original series.In the early 1990s, several companies began to experiment with the licensing of less children-oriented material. Some, such as A.D. Vision, and Central Park Media and its imprints, achieved fairly substantial commercial success and went on to become major players in the now very lucrative American anime market. Others, such as AnimEigo, achieved limited success. Many companies created directly by Japanese parent companies did not do as well, most releasing only one or two titles before completing their American operations. Licenses are expensive, often hundreds of thousands of dollars for one series and tens of thousands for one movie. The prices vary widely; for example, Jinki: Extend cost only $91,000 to license while Kurau Phantom Memory cost $960,000. Simulcast Internet streaming rights can be less expensive, with prices around $1,000-$2,000 an episode, but can also be more expensive, with some series costing more than US$200,000 per episode.The anime market for the United States was worth approximately $2.74 billion in 2009. Dubbed animation began airing in the United States in 2000 on networks like The WB and Cartoon Network's Adult Swim. In 2005, this resulted in five of the top ten anime titles having previously aired on Cartoon Network. As a part of localization, some editing of cultural references may occur to better follow the references of the non-Japanese culture. The cost of English localization averages US $10,000 per episode.The industry has been subject to both praise and condemnation for fansubs, the addition of unlicensed and unauthorized subtitled translations of anime series or films. Fansubs, which were originally distributed on VHS bootlegged cassettes in the 1980s, have been freely available and disseminated online since the 1990s. Since this practice raises concerns for copyright and piracy issues, fansubbers tend to adhere to an unwritten moral code to destroy or no longer distribute an anime once an official translated or subtitled version becomes licensed. They also try to encourage viewers to buy an official copy of the release once it comes out in English, although fansubs typically continue to circulate through file sharing networks. Even so, the laid back regulations of the Japanese animation industry tends to overlook these issues, allowing it to grow underground and thus increasing the popularity until there is a demand for official high quality releases for animation companies. This has led to an increase in global popularity with Japanese animations, reaching $40 million in sales in 2004.Legal international availability of anime on the Internet has changed in recent years, with simulcasts of series available on websites like Crunchyroll. === Markets === Japan External Trade Organization (JETRO) valued the domestic anime market in Japan at ¥2.4 trillion (US$24 billion), including ¥2 trillion from licensed products, in 2005. JETRO reported sales of overseas anime exports in 2004 to be ¥2 trillion (US$18 billion). JETRO valued the anime market in the United States at ¥520 billion (US$5.2 billion), including US$500 million in home video sales and over US$4 billion from licensed products, in 2005. JETRO projected in 2005 that the worldwide anime market, including sales of licensed products, would grow to ¥10 trillion (US$100 billion). The anime market in China was valued at US$21 billion in 2017, and is projected to reach US$31 billion by 2020. === Awards === The anime industry has several annual awards which honor the year's best works. Major annual awards in Japan include the Ōfuji Noburō Award, the Mainichi Film Award for Best Animation Film, the Animation Kobe Awards, the Japan Media Arts Festival animation awards, the Tokyo Anime Award and the Japan Academy Prize for Animation of the Year. In the United States, anime films compete in the ICv2.com Anime Awards There were also the American Anime Awards, which were designed to recognize excellence in anime titles nominated by the industry, and were held only once in 2006. Anime productions have also been nominated and won awards not exclusively for anime, like the Academy Award for Best Animated Feature or the Golden Bear. == Globalization == Anime has become commercially profitable in Western countries, as demonstrated by early commercially successful Western adaptations of anime, such as Astro Boy, Dragon Ball and Speed Racer. Early American adaptions in the 1960s made Japan expand into the continental European market, first with productions aimed at European and Japanese children, such as Heidi, Vicky the Viking and Barbapapa, which aired in various countries. Particularly Italy, Spain and France grew an interest into Japan's output, due to its cheap selling price and productive output. In fact, Italy imported the most anime outside of Japan. These mass imports influenced anime popularity in South American, Arabic and German markets.The beginning of 1980 saw the introduction of Japanese anime series into the American culture. In the 1990s, Japanese animation slowly gained popularity in America. Media companies such as Viz and Mixx began publishing and releasing animation into the American market. The growth of the Internet provided Western audiences an easy way to access Japanese content. This is especially the case with net services such as Netflix and Crunchyroll. As a direct result, various interests surrounding Japan has increased. === Fan response === Anime clubs gave rise to anime conventions in the 1990s with the "anime boom", a period marked by increased popularity of anime. These conventions are dedicated to anime and manga and include elements like cosplay contests and industry talk panels. Cosplay, a portmanteau for "costume play", is not unique to anime and has become popular in contests and masquerades at anime conventions. Japanese culture and words have entered English usage through the popularity of the medium, including otaku, a derogatory Japanese term commonly used in English to denote a fan of anime and manga. Another word that has arisen describing fans in the United States is wapanese meaning White individuals who desire to be Japanese, or later known as weeaboo for individuals who demonstrate a strong interest in Japanese anime subculture, which is a term that originated from abusive content posted on the popular bulletin board website 4chan.org. Anime enthusiasts have produced fan fiction and fan art, including computer wallpaper and anime music videos.As of the 2010s, many anime fans use online communities and databases such as MyAnimeList to discuss anime and track their progress watching respective series. === Anime style === One of the key points that made anime different from popular Western animation is the emotional content. Once the expectation that the aspects of visual intrigue or animation being just for children is put aside, the audience can realize that many emotions such as suffering, death, pain, struggle, and joy can all be storytelling elements utilized in anime as much as other types of media. However, as anime itself became increasingly popular, anime styling has been inevitably the subject of both satire and serious creative productions. South Park's "Chinpokomon" and "Good Times with Weapons" episodes, Adult Swim's Perfect Hair Forever, and Nickelodeon's Kappa Mikey are examples of satirical depictions of Japanese culture and anime. Some works have sparked debate for blurring the lines between satire and serious "anime style" productions, such as the American anime style production Avatar: The Last Airbender. These anime styled works have become defined as anime-influenced animation, in an attempt to classify all anime styled works of non-Japanese origin. Some creators of these works cite anime as a source of inspiration and like the French production team for Ōban Star-Racers moved to Tokyo to collaborate with a Japanese production team. When anime is defined as a "style" rather than as a national product it leaves open the possibility of anime being produced in other countries. A U.A.E.-Filipino produced TV series called Torkaizer is dubbed as the "Middle East's First Anime Show", and is currently in production, which is currently looking for funding. The web-based series RWBY is produced using an anime art style and has been declared to be anime. In addition, the series will be released in Japan, under the label of "anime" per the Japanese definition of the term and referenced as an "American-made anime". Netflix declared the company's intention to produce anime. In doing so, the company is offering a more accessible channel for distribution to Western markets. Defining anime as style has been contentious amongst fans, with John Oppliger stating, "The insistence on referring to original American art as Japanese "anime" or "manga" robs the work of its cultural identity." == See also == List of anime List of highest-grossing anime films Animation director Chinese animation Fandom culture in South Korea Korean animation Mechademia Voice acting in Japan == References == === Notes === === Sources === === Bibliography === == External links == Anime at Curlie (based on DMOZ) ### Answer: <1917 introductions>, <Anime>, <Anime and manga terminology>, <Japanese inventions>

### Instruction: retrieve labels for this: Ankara (English ; Turkish [ˈaŋkaɾa] ( listen)), historically known as Ancyra and Angora, is the capital of the Republic of Turkey. With a population of 4,587,558 in the urban center (2014) and 5,150,072 in its province (2015), it is Turkey's second largest city after Istanbul (the former imperial capital), having outranked İzmir in the 20th century. On 23 April 1920 the Grand National Assembly of Turkey was established in Ankara, which became the headquarters of Atatürk and the Turkish National Movement during the Turkish War of Independence. Ankara has been the capital of the Turkish Republic since its establishment on 29 October 1923, having replaced the former Turkish capital Istanbul (Constantinople) following the fall of the Ottoman Empire. The government is a prominent employer, but Ankara is also an important commercial and industrial city, located at the center of Turkey's road and railway networks. The city gave its name to the Angora wool shorn from Angora rabbits, the long-haired Angora goat (the source of mohair), and the Angora cat. The area is also known for its pears, honey and muscat grapes. Although situated in one of the driest places of Turkey and surrounded mostly by steppe vegetation except for the forested areas on the southern periphery, Ankara can be considered a green city in terms of green areas per inhabitant, at 72 square metres (775 square feet) per head.Ankara is a very old city with various Hittite, Phrygian, Hellenistic, Roman, Byzantine, and Ottoman archaeological sites. The historical center of town is a rocky hill rising 150 m (500 ft) over the left bank of the Ankara Çayı, a tributary of the Sakarya River, the classical Sangarius. The hill remains crowned by the ruins of the old citadel. Although few of its outworks have survived, there are well-preserved examples of Roman and Ottoman architecture throughout the city, the most remarkable being the 20 BC Temple of Augustus and Rome that boasts the Monumentum Ancyranum, the inscription recording the Res Gestae Divi Augusti. == Etymology and names == The orthography of the name Ankara has varied over the ages. It has been identified with the Hittite cult center Ankuwaš, although this remains a matter of debate. In classical antiquity and during the medieval period, the city was known as Ánkyra (Ἄγκυρα, lit "anchor") in Greek and Ancyra in Latin; the Galatian Celtic name was probably a similar variant. Following its annexation by the Seljuk Turks in 1073, the city became known in many European languages as Angora; it was also known in Ottoman Turkish as Engürü. The form "Angora" is preserved in the names of breeds of many different kinds of animals, and in the names of several locations in the US (see Angora). == Geography == === Climate === Ankara has a hot-summer Mediterranean climate (Köppen Csa) which closely borders a hot summer Mediterranean continental climate (Köppen Dsa). Under the Trewartha climate classification, Ankara has a middle latitude steppe climate (BSk). Due to its elevation and inland location, Ankara has cold, somewhat snowy winters and hot, dry summers. Rainfall occurs mostly during the spring and autumn. Ankara lies in USDA Hardiness zone 7b, and its annual average precipitation is fairly low at 400 millimeters (16 in), nevertheless precipitation can be observed throughout the year. Monthly mean temperatures range from 0.3 °C (32.5 °F) in January to 23.5 °C (74.3 °F) in July, with an annual mean of 12.02 °C (53.6 °F). === Demographics === Ankara had a population of 75,000 in 1927. In 2013, Ankara Province had a population of 5,045,083.When Ankara became the capital of the Republic of Turkey in 1923, it was designated as a planned city for 500,000 future inhabitants. During the 1920s, 1930s and 1940s, the city grew in a planned and orderly pace. However, from the 1950s onward, the city grew much faster than envisioned, because unemployment and poverty forced people to migrate from the countryside into the city in order to seek a better standard of living. As a result, many illegal houses called gecekondu were built around the city, causing the unplanned and uncontrolled urban landscape of Ankara, as not enough planned housing could be built fast enough. Although precariously built, the vast majority of them have electricity, running water and modern household amenities. Nevertheless, many of these gecekondus have been replaced by huge public housing projects in the form of tower blocks such as Elvankent, Eryaman and Güzelkent; and also as mass housing compounds for military and civil service accommodation. Although many gecekondus still remain, they too are gradually being replaced by mass housing compounds, as empty land plots in the city of Ankara for new construction projects are becoming impossible to find. == History == The region's history can be traced back to the Bronze Age Hattic civilization, which was succeeded in the 2nd millennium BC by the Hittites, in the 10th century BC by the Phrygians, and later by the Lydians, Persians, Greeks, Galatians, Romans, Byzantines, and Turks (the Seljuk Sultanate of Rûm, the Ottoman Empire and finally republican Turkey). === Ancient history === The oldest settlements in and around the city center of Ankara belonged to the Hattic civilization which existed during the Bronze Age and was gradually absorbed c. 2000–1700 BC by the Indo-European Hittites. The city grew significantly in size and importance under the Phrygians starting around 1000 BC, and experienced a large expansion following the mass migration from Gordion, (the capital of Phrygia), after an earthquake which severely damaged that city around that time. In Phrygian tradition, King Midas was venerated as the founder of Ancyra, but Pausanias mentions that the city was actually far older, which accords with present archaeological knowledge.Phrygian rule was succeeded first by Lydian and later by Persian rule, though the strongly Phrygian character of the peasantry remained, as evidenced by the gravestones of the much later Roman period. Persian sovereignty lasted until the Persians' defeat at the hands of Alexander the Great who conquered the city in 333 BC. Alexander came from Gordion to Ankara and stayed in the city for a short period. After his death at Babylon in 323 BC and the subsequent division of his empire among his generals, Ankara and its environs fell into the share of Antigonus. Another important expansion took place under the Greeks of Pontos who came there around 300 BC and developed the city as a trading center for the commerce of goods between the Black Sea ports and Crimea to the north; Assyria, Cyprus, and Lebanon to the south; and Georgia, Armenia and Persia to the east. By that time the city also took its name Ἄγκυρα (Ánkyra, meaning anchor in Greek) which, in slightly modified form, provides the modern name of Ankara. === Celtic history === In 278 BC, the city, along with the rest of central Anatolia, was occupied by a Celtic group, the Galatians, who were the first to make Ankara one of their main tribal centers, the headquarters of the Tectosages tribe. Other centers were Pessinos, today's Balhisar, for the Trocmi tribe, and Tavium, to the east of Ankara, for the Tolstibogii tribe. The city was then known as Ancyra. The Celtic element was probably relatively small in numbers; a warrior aristocracy which ruled over Phrygian-speaking peasants. However, the Celtic language continued to be spoken in Galatia for many centuries. At the end of the 4th century, St. Jerome, a native of Dalmatia, observed that the language spoken around Ankara was very similar to that being spoken in the northwest of the Roman world near Trier. === Roman history === The city was subsequently passed under the control of the Roman Empire. In 25 BC, Emperor Augustus raised it to the status of a polis and made it the capital city of the Roman province of Galatia. Ankara is famous for the Monumentum Ancyranum (Temple of Augustus and Rome) which contains the official record of the Acts of Augustus, known as the Res Gestae Divi Augusti, an inscription cut in marble on the walls of this temple. The ruins of Ancyra still furnish today valuable bas-reliefs, inscriptions and other architectural fragments. Two other Galatian tribal centers, Tavium near Yozgat, and Pessinus (Balhisar) to the west, near Sivrihisar, continued to be reasonably important settlements in the Roman period, but it was Ancyra that grew into a grand metropolis. An estimated 200,000 people lived in Ancyra in good times during the Roman Empire, a far greater number than was to be the case from after the fall of the Roman Empire until the early 20th century. A small river, the Ankara Çayı, ran through the center of the Roman town. It has now been covered and diverted, but it formed the northern boundary of the old town during the Roman, Byzantine and Ottoman periods. Çankaya, the rim of the majestic hill to the south of the present city center, stood well outside the Roman city, but may have been a summer resort. In the 19th century, the remains of at least one Roman villa or large house were still standing not far from where the Çankaya Presidential Residence stands today. To the west, the Roman city extended until the area of the Gençlik Park and Railway Station, while on the southern side of the hill, it may have extended downwards as far as the site presently occupied by Hacettepe University. It was thus a sizeable city by any standards and much larger than the Roman towns of Gaul or Britannia.Ancyra's importance rested on the fact that it was the junction point where the roads in northern Anatolia running north-south and east-west intersected, giving it major strategic importance for Rome's eastern frontier. The great imperial road running east passed through Ankara and a succession of emperors and their armies came this way. They were not the only ones to use the Roman highway network, which was equally convenient for invaders. In the second half of the 3rd century, Ancyra was invaded in rapid succession by the Goths coming from the west (who rode far into the heart of Cappadocia, taking slaves and pillaging) and later by the Arabs. For about a decade, the town was one of the western outposts of one of Palmyrean empress Zenobia in the Syrian Desert, who took advantage of a period of weakness and disorder in the Roman Empire to set up a short-lived state of her own. The town was reincorporated into the Roman Empire under Emperor Aurelian in 272. The tetrarchy, a system of multiple (up to four) emperors introduced by Diocletian (284–305), seems to have engaged in a substantial programme of rebuilding and of road construction from Ankara westwards to Germe and Dorylaeum (now Eskişehir). In its heyday, Roman Ankara was a large market and trading center but it also functioned as a major administrative capital, where a high official ruled from the city's Praetorium, a large administrative palace or office. During the 3rd century, life in Ancyra, as in other Anatolian towns, seems to have become somewhat militarized in response to the invasions and instability of the town. === Byzantine history === The city is well known during the 4th century as a centre of Christian activity (see also below), due to frequent imperial visits, and through the letters of the pagan scholar Libanius. Bishop Marcellus of Ancyra and Basil of Ancyra were active in the theological controversies of their day, and the city was the site of no less than three church synods in 314, 358 and 375, the latter two in favour of Arianism. The city was visited by Emperor Constans I (r. 337–350) in 347 and 350, Julian (r. 361–363) during his Persian campaign in 362, and Julian's successor Jovian (r. 363–364) in winter 363/364 (he entered his consulship while in the city). After Jovian's death soon after, Valentinian I (r. 364–375) was acclaimed emperor at Ancyra, and in the next year his brother Valens (r. 364–378) used Ancyra as his base against the usurper Procopius. When the province of Galatia was divided sometime in 396/99, Ancyra remained the civil capital of Galatia I, as well as its ecclesiastical centre (metropolitan see). Emperor Arcadius (r. 395–408) frequently used the city as his summer residence, and some information about the ecclesiastical affairs of the city during the early 5th century is found in the works of Palladius of Galatia and Nilus of Galatia.In 479, the rebel Marcian attacked the city, without being able to capture it. In 610/11, Comentiolus, brother of Emperor Phocas (r. 602–610), launched his own unsuccessful rebellion in the city against Heraclius (r. 610–641). Ten years later, in 620 or more likely 622, it was captured by the Sassanid Persians during the Byzantine–Sassanid War of 602–628. Although the city returned to Byzantine hands after the end of the war, the Persian presence left traces in the city's archaeology, and likely began the process of its transformation from a late antique city to a medieval fortified settlement.In 654, the city was captured for the first time by the Arabs of the Rashidun Caliphate, under Muawiyah, the future founder of the Umayyad Caliphate. At about the same time, the themes were established in Anatolia, and Ancyra became capital of the Opsician Theme, which was the largest and most important theme until it was split up under Emperor Constantine V (r. 741–775); Ancyra then became the capital of the new Bucellarian Theme. The city was attacked without success by Abbasid forces in 776 and in 798/99. In 805, Emperor Nikephoros I (r. 802–811) strengthened its fortifications, a fact which probably saved it from sack during the large-scale invasion of Anatolia by Caliph Harun al-Rashid in the next year. Arab sources report that Harun and his successor al-Ma'mun (r. 813–833) took the city, but this information is later invention. In 838, however, during the Amorium campaign, the armies of Caliph al-Mu'tasim (r. 833–842) converged and met at the city; abandoned by its inhabitants, Ancara was razed to the ground, before the Arab armies went on to besiege and destroy Amorium. In 859, Emperor Michael III (r. 842–867) came to the city during a campaign against the Arabs, and ordered its fortifications restored. In 872, the city was menaced, but not taken, by the Paulicians under Chrysocheir. The last Arab raid to reach the city was undertaken in 931, by the Abbasid governor of Tarsus, Thamal al-Dulafi, but the city again was not captured. === Turkic rulers === After the Battle of Manzikert in 1071, the Seljuk Turks overran much of Anatolia. By 1073, the Turkish settlers had reached the vicinity of Ancyra, and the city was captured shortly after, at the latest by the time of the rebellion of Nikephoros Melissenos in 1081. In 1101, when the Crusade under Raymond IV of Toulouse arrived, the city had been under Danishmend control for some time. The Crusaders captured the city, and handed it over to the Byzantine emperor Alexios I Komnenos (r. 1081–1118). Byzantine rule did not last long, and the city was captured by the Seljuk Sultanate of Rum at some unknown point; in 1127, it returned to Danishmend control until 1143, when the Seljuks of Rum retook it.After the Battle of Köse Dağ in 1243, in which the Mongols defeated the Seljuks, most of Anatolia became part of the dominion of the Mongols. Taking advantage of Seljuk decline, a semi-religious cast of craftsmen and trade people named Ahiler chose Ankara as their independent city-state in 1290. Orhan I, the second Bey of the Ottoman Empire, captured the city in 1356. Timur defeated Bayezid I at the Battle of Ankara in 1402 and took the city, but in 1403 Ankara was again under Ottoman control. The Levant Company maintained a factory in the town from 1639 to 1768. In the 19th century, its population was estimated at 20,000 to 60,000. It was sacked by Egyptians under Ibrahim Pasha in 1832. Prior to World War I, the town had a British consulate and a population of around 28,000, roughly ⅓ of whom were Christian. === Turkish republican capital === Following the Ottoman defeat at World War I, the Ottoman capital Constantinople (modern Istanbul) and much of Anatolia were occupied by the Allies, who planned to share these lands between Armenia, France, Greece, Italy and the United Kingdom, leaving for the Turks the core piece of land in central Anatolia. In response, the leader of the Turkish nationalist movement, Mustafa Kemal Atatürk, established the headquarters of his resistance movement in Ankara in 1920. After the Turkish War of Independence was won and the Treaty of Sèvres was superseded by the Treaty of Lausanne, the Turkish nationalists replaced the Ottoman Empire with the Republic of Turkey on 29 October 1923. A few days earlier, Ankara had officially replaced Constantinople as the new Turkish capital city, on 13 October 1923. After Ankara became the capital of the newly founded Republic of Turkey, new development divided the city into an old section, called Ulus, and a new section, called Yenişehir. Ancient buildings reflecting Roman, Byzantine, and Ottoman history and narrow winding streets mark the old section. The new section, now centered on Kızılay Square, has the trappings of a more modern city: wide streets, hotels, theaters, shopping malls, and high-rises. Government offices and foreign embassies are also located in the new section. Ankara has experienced a phenomenal growth since it was made Turkey's capital in 1923, when it was "a small town of no importance". In 1924, the year after the government had moved there, Ankara had about 35,000 residents. By 1927 there were 44,553 residents and by 1950 the population had grown to 286,781. Ankara continued to grow rapidly during the latter half of the 20th century and eventually outranked Izmir as Turkey's second largest city, after Istanbul. Ankara's urban population reached 4,587,558 in 2014, while the population of Ankara Province reached 5,150,072 in 2015. === Ecclesiastical history === Early Christian martyrs of Ancyra, about whom little is known, included Proklos and Hilarios who were natives of the otherwise unknown nearby village of Kallippi, and suffered repression under the emperor Trajan (98–117). In the 280s we hear of Philumenos, a Christian corn merchant from southern Anatolia, being captured and martyred in Ankara, and Eustathius. As in other Roman towns, the reign of Diocletian marked the culmination of the persecution of the Christians. In 303, Ancyra was one of the towns where the co-Emperors Diocletian and his deputy Galerius launched their anti-Christian persecution. In Ancyra, their first target was the 38-year-old Bishop of the town, whose name was Clement. Clement's life describes how he was taken to Rome, then sent back, and forced to undergo many interrogations and hardship before he, and his brother, and various companions were put to death. The remains of the church of St. Clement can be found today in a building just off Işıklar Caddesi in the Ulus district. Quite possibly this marks the site where Clement was originally buried. Four years later, a doctor of the town named Plato and his brother Antiochus also became celebrated martyrs under Galerius. Theodotus of Ancyra is also venerated as a saint. However, the persecution proved unsuccessful and in 314 Ancyra was the center of an important council of the early church; its 25 disciplinary canons constitute one of the most important documents in the early history of the administration of the Sacrament of Penance. No one cares about History am I right. The synod also considered ecclesiastical policy for the reconstruction of the Christian Church after the persecutions, and in particular the treatment of lapsi—Christians who had given in to forced paganism (sacrifices) to avoid martyrdom during these persecutions. Though paganism was probably tottering in Ancyra in Clement's day, it may still have been the majority religion. Twenty years later, Christianity and monotheism had taken its place. Ancyra quickly turned into a Christian city, with a life dominated by monks and priests and theological disputes. The town council or senate gave way to the bishop as the main local figurehead. During the middle of the 4th century, Ancyra was involved in the complex theological disputes over the nature of Christ, and a form of Arianism seems to have originated there.In 362–363, the Emperor Julian passed through Ancyra on his way to an ill-fated campaign against the Persians, and according to Christian sources, engaged in a persecution of various holy men. The stone base for a statue, with an inscription describing Julian as "Lord of the whole world from the British Ocean to the barbarian nations", can still be seen, built into the eastern side of the inner circuit of the walls of Ankara Castle. The Column of Julian which was erected in honor of the emperor's visit to the city in 362 still stands today. In 375, Arian bishops met at Ancyra and deposed several bishops, among them St. Gregory of Nyssa. In the late 4th century, Ancyra became something of an imperial holiday resort. After Constantinople became the East Roman capital, emperors in the 4th and 5th centuries would retire from the humid summer weather on the Bosporus to the drier mountain atmosphere of Ancyra. Theodosius II (408–450) kept his court in Ancyra in the summers. Laws issued in Ancyra testify to the time they spent there. The Metropolis of Ancyra continued to be a residential see of the Eastern Orthodox Church until the 20th century, with about 40,000 faithful, mostly Turkish-speaking, but that situation ended as a result of the 1923 Convention Concerning the Exchange of Greek and Turkish Populations. The earlier Armenian Genocide put an end to the residential eparchy of Ancyra of the Armenian Catholic Church, which had been established in 1850. It is also a titular metropolis of the Ecumenical Patriarchate of Constantinople. Both the Ancient Byzantine Metropolitan archbishopric and the 'modern' Armenian eparchy are now listed by the Catholic Church as titular sees, with separate apostolic successions. ==== Armenian Catholic (titular) see ==== In 1735 an Armenian Catholic diocese was established (Curiate Italian: Ancira degli Ameni). Having fallen into disuse, it was restored on 30 April 1850. The Armenian Genocide brought an effective end to the residential diocese, which was only formally suppressed in 1972 and instantly transformed into an Armenian Catholic titular bishopric. The titular see has had a single occupant: Mikail Nersès Sétian (3 July 1981 – death 9 September 2002), as Apostolic Exarch of United States of America and Canada of the Armenians (USA) (3 July 1981 – retired 18 September 1993) and as emeritate. ==== Latin titular archbishopric ==== No later than 1696, the Catholic Church also established a Latin Rite titular archbishopric of Ancyra. The last incumbent died in 1976. ==== Saint Clement Church ==== The Saint Clement Church is the only structure survived from the Byzantine era in Ankara. The church is believed to have been built between the 4th and 9th centuries. At the time of the Ottoman Sultan Murad II, a mosque and madrasah were built on top of the church. Today, only the interior facade of a wall and marble blocks from the church have survived. == Economy and infrastructure == The city has exported mohair (from the Angora goat) and Angora wool (from the Angora rabbit) internationally for centuries. In the 19th century, the city also exported substantial amounts of goat and cat skins, gum, wax, honey, berries, and madder root. It was connected to Istanbul by railway before the First World War, continuing to export mohair, wool, berries, and grain.The Central Anatolia Region is one of the primary locations of grape and wine production in Turkey, and Ankara is particularly famous for its Kalecik Karası and Muscat grapes; and its Kavaklıdere wine, which is produced in the Kavaklıdere neighbourhood within the Çankaya district of the city. Ankara is also famous for its pears. Another renowned natural product of Ankara is its indigenous type of honey (Ankara Balı) which is known for its light color and is mostly produced by the Atatürk Forest Farm and Zoo in the Gazi district, and by other facilities in the Elmadağ, Çubuk and Beypazarı districts. Ankara is the center of the state-owned and private Turkish defence and aerospace companies, where the industrial plants and headquarters of the Turkish Aerospace Industries, MKE, ASELSAN, Havelsan, Roketsan, FNSS, Nurol Makina, and numerous other firms are located. Exports to foreign countries from these defence and aerospace firms have steadily increased in the past decades. The IDEF in Ankara is one of the largest international expositions of the global arms industry. A number of the global automotive companies also have production facilities in Ankara, such as the German bus and truck manufacturer MAN SE. Ankara hosts the OSTIM Industrial Zone, Turkey's largest industrial park. A large percentage of the complicated employment in Ankara is provided by the state institutions; such as the ministries, undersecretariats, and other administrative bodies of the Turkish government. There are also many foreign citizens working as diplomats or clerks in the embassies of their respective countries. === Transportation === The Electricity, Gas, Bus General Directorate (EGO) operates the Ankara Metro and other forms of public transportation. Ankara is currently served by a suburban rail named Ankaray (A1) and three subway lines (M1, M2, M3) of the Ankara Metro with about 300,000 total daily commuters, while an additional subway line (M4) is currently under construction. A 3.2 km (2.0 mi) long gondola lift with four stations connects the district of Şentepe to the Yenimahalle metro station.The Ankara Central Station is a major rail hub in Turkey. The Turkish State Railways operates passenger train service from Ankara to other major cities, such as: Istanbul, Eskişehir, Balıkesir, Kütahya, İzmir, Kayseri, Adana, Kars, Elâzığ, Malatya, Diyarbakır, Karabük, Zonguldak and Sivas. Commuter rail also runs between the stations of Sincan and Kayaş. On 13 March 2009, the new Yüksek Hızlı Tren (YHT) high-speed rail service began operation between Ankara and Eskişehir. On 23 August 2011, another YHT high-speed line commercially started its service between Ankara and Konya. On 25 July 2014, the Ankara–Istanbul high-speed line of YHT entered service.Esenboğa International Airport, located in the north-east of the city, is Ankara's main airport. ==== Ankara Public Transportation Statistics ==== The average amount of time people spend commuting with public transit in Ankara, for example to and from work, on a weekday is 71 min. 17% of public transit riders, ride for more than 2 hours every day. The average amount of time people wait at a stop or station for public transit is 16 min, while 28.% of riders wait for over 20 minutes on average every day. The average distance people usually ride in a single trip with public transit is 9.9 km (6.2 mi), while 27% travel for over 12 km (7.5 mi) in a single direction. == Politics == Ankara is politically a triple battleground between the ruling conservative Justice and Development Party (AKP), the opposition Kemalist centre-left Republican People's Party (CHP) and the nationalist far-right Nationalist Movement Party (MHP). The province of Ankara is divided into 25 districts. The CHP's key and almost only political stronghold in Ankara lies within the central area of Çankaya, which is the city's most populous district. While the CHP has always gained between 60 and 70% of the vote in Çankaya since 2002, political support elsewhere throughout Ankara is minimal. The high population within Çankaya, as well as Yenimahalle to an extent, has allowed the CHP to take overall second place behind the AKP in both local and general elections, with the MHP a close third, despite the fact that the MHP is politically stronger than the CHP in almost every other district. Overall, the AKP enjoys the most support throughout the city. The electorate of Ankara thus tend to vote in favour of the political right, far more so than the other main cities of Istanbul and İzmir. In retrospect, the 2013–14 protests against the AKP government were particularly strong in Ankara, proving to be fatal on multiple occasions.Melih Gökçek has been the Metropolitan Mayor of Ankara since 1994 as a politician from the Welfare Party. He later joined the Virtue Party and then the AKP. Initially elected in the 1994 local elections, he was re-elected in 1999, 2004 and 2009. In the 2014 local election, Gökçek stood for a fifth term. The MHP metropolitan mayoral candidate for the 2009 local elections, conservative politician Mansur Yavaş, stood as the CHP candidate against Gökçek. In a heavily controversial election, Gökçek was declared the winner by just 1% ahead of Yavaş amid allegations of systematic electoral fraud. With the Supreme Electoral Council and courts rejecting Yavaş's appeals, he has declared intention to take the irregularities to the European Court of Human Rights. Although Gökçek was inaugurated for a fifth term, most election observers believe that Yavaş was the winner of the election.Gökçek is resigned on 28 October 2017, replaced by former mayor of Sincan, Mustafa Tuna. The city suffered from a series of terrorist attacks in 2015 and 2016, most notably on 10 October 2015; 17 February 2016; 13 March 2016; and 15 July 2016. == Main sights == === Ancient/archeological sites === ==== Ankara Citadel ==== The foundations of the Ankara castle and citadel were laid by the Galatians on a prominent lava outcrop (39.941°N 32.864°E / 39.941; 32.864), and the rest was completed by the Romans. The Byzantines and Seljuks further made restorations and additions. The area around and inside the citadel, being the oldest part of Ankara, contains many fine examples of traditional architecture. There are also recreational areas to relax. Many restored traditional Turkish houses inside the citadel area have found new life as restaurants, serving local cuisine. The citadel was depicted in various Turkish banknotes during 1927–1952 and 1983–1989. ==== Roman Theatre ==== The remains, the stage, and the backstage of the Roman theatre can be seen outside the castle. Roman statues that were found here are exhibited in the Museum of Anatolian Civilizations. The seating area is still under excavation. ==== Temple of Augustus and Rome ==== The Augusteum, now known as the Temple of Augustus and Rome, was built 25 x 20 BC following the conquest of Central Anatolia by the Roman Empire. Ancyra then formed the capital of the new province of Galatia. After the death of Augustus in AD 14, a copy of the text of the Res Gestae Divi Augusti (the Monumentum Ancyranum) was inscribed on the interior of the temple's pronaos in Latin and a Greek translation on an exterior wall of the cella. The temple on the ancient acropolis of Ancyra was enlarged in the 2nd century and converted into a church in the 5th century. It is located in the Ulus quarter of the city. It was subsequently publicized by the Austrian ambassador Ogier Ghiselin de Busbecq in the 16th century. ==== Roman Baths ==== The Roman Baths of Ankara have all the typical features of a classical Roman bath complex: a frigidarium (cold room), a tepidarium (warm room) and a caldarium (hot room). The baths were built during the reign of the Roman emperor Caracalla in the early 3rd century to honor Asclepios, the God of Medicine. Today, only the basement and first floors remain. It is situated in the Ulus quarter. ==== Roman Road ==== The Roman Road of Ankara or Cardo Maximus was found in 1995 by Turkish archaeologist Cevdet Bayburtluoğlu. It is 216 metres (709 feet) long and 6.7 metres (22.0 feet) wide. Many ancient artifacts were discovered during the excavations along the road and most of them are currently displayed at the Museum of Anatolian Civilizations. ==== Column of Julian ==== The Column of Julian or Julianus, now in the Ulus district, was erected in honor of the Roman emperor Julian the Apostate's visit to Ancyra in 362. === Mosques === ==== Kocatepe Mosque ==== Kocatepe Mosque is the largest mosque in the city.

The mimber (pulpit) and mihrap (prayer niche) are of white marble, and the mosque itself is of Ankara stone, an example of very fine workmanship. ==== Hacı Bayram Mosque ==== This mosque, in the Ulus quarter next to the Temple of Augustus, was built in the early 15th century in Seljuk style by an unknown architect. It was subsequently restored by architect Mimar Sinan in the 16th century, with Kütahya tiles being added in the 18th century. The mosque was built in honor of Hacı Bayram-ı Veli, whose tomb is next to the mosque, two years before his death (1427–28). The usable space inside this mosque is 437 m2 (4,704 sq ft) on the first floor and 263 m2 (2,831 sq ft) on the second floor. ==== Ahi Elvan Mosque ==== It was founded in the Ulus quarter near the Ankara Citadel and was constructed by the Ahi fraternity during the late 14th and early 15th centuries. The finely carved walnut mimber (pulpit) is of particular interest. ==== Alâeddin Mosque ==== The Alâeddin Mosque is the oldest mosque in Ankara. It has a carved walnut mimber, the inscription on which records that the mosque was completed in early AH 574 (which corresponds to the summer of 1178 AD) and was built by the Seljuk prince Muhiddin Mesud Şah (d. 1204), the Bey of Ankara, who was the son of the Anatolian Seljuk sultan Kılıç Arslan II (reigned 1156–1192.) === Modern monuments === ==== Victory Monument ==== The Victory Monument (Turkish: Zafer Anıtı) was crafted by Austrian sculptor Heinrich Krippel in 1925 and was erected in 1927 at Ulus Square. The monument is made of marble and bronze and features an equestrian statue of Mustafa Kemal Atatürk, who wears a Republic era modern military uniform, with the rank Field Marshal. ==== Statue of Atatürk ==== Located at Zafer Square (Turkish: Zafer Meydanı), the marble and bronze statue was crafted by the renowned Italian sculptor Pietro Canonica in 1927 and depicts a standing Atatürk who wears a Republic era modern military uniform, with the rank Field Marshal. ==== Monument to a Secure, Confident Future ==== This monument, located in Güven Park near Kızılay Square, was erected in 1935 and bears Atatürk's advice to his people: "Turk! Be proud, work hard, and believe in yourself." The monument was depicted on the reverse of the Turkish 5 lira banknote of 1937–1952 and of the 1000 lira banknotes of 1939–1946. ==== Hatti Monument ==== Erected in 1978 at Sıhhiye Square, this impressive monument symbolizes the Hatti Sun Disc (which was later adopted by the Hittites) and commemorates Anatolia's earliest known civilization. The Hatti Sun Disc has been used in the previous logo of Ankara Metropolitan Municipality. It was also used in the previous logo of the Ministry of Culture & Tourism. === Inns === ==== Suluhan ==== Suluhan is a historical Inn in Ankara. It is also called the Hasanpaşa Han. It is about 400 meters (1,300 ft) southeast of Ulus Square and situated in the Hacıdoğan neighbourhood. According to the vakfiye (inscription) of the building, the Ottoman era han was commissioned by Hasan Pasha, a regional beylerbey, and was constructed between 1508 and 1511, during the final years of the reign of Sultan Bayezid II. There are 102 rooms (now shops) which face the two yards. In each room there is a window, a niche and a chimney. ==== Çengelhan Rahmi Koç Museum ==== Çengelhan Rahmi Koç Museum is a museum of industrial technology situated in Çengel Han, an Ottoman era Inn which was completed in 1523, during the early years of the reign of Sultan Suleiman the Magnificent. The exhibits include industrial/technological artifacts from the 1850s onwards. There are also sections about Mustafa Kemal Atatürk, the founder of modern Turkey; Vehbi Koç, Rahmi Koç's father and one of the first industrialists of Turkey, and Ankara city. == Shopping == Foreign visitors to Ankara usually like to visit the old shops in Çıkrıkçılar Yokuşu (Weavers' Road) near Ulus, where myriad things ranging from traditional fabrics, hand-woven carpets and leather products can be found at bargain prices. Bakırcılar Çarşısı (Bazaar of Coppersmiths) is particularly popular, and many interesting items, not just of copper, can be found here like jewelry, carpets, costumes, antiques and embroidery. Up the hill to the castle gate, there are many shops selling a huge and fresh collection of spices, dried fruits, nuts, and other produce. Modern shopping areas are mostly found in Kızılay, or on Tunalı Hilmi Avenue, including the modern mall of Karum (named after the ancient Assyrian merchant colonies called Kârum that were established in central Anatolia at the beginning of the 2nd millennium BC) which is located towards the end of the Avenue; and in Çankaya, the quarter with the highest elevation in the city. Atakule Tower next to Atrium Mall in Çankaya has views over Ankara and also has a revolving restaurant at the top. The symbol of the Armada Shopping Mall is an anchor, and there's a large anchor monument at its entrance, as a reference to the ancient Greek name of the city, Ἄγκυρα (Ánkyra), which means anchor. Likewise, the anchor monument is also related with the Spanish name of the mall, Armada, which means naval fleet. As Ankara started expanding westward in the 1970s, several modern, suburbia-style developments and mini-cities began to rise along the western highway, also known as the Eskişehir Road. The Armada,CEPA and Kentpark malls on the highway, the Galleria, Arcadium and Gordion in Ümitköy, and a huge mall, Real in Bilkent Center, offer North American and European style shopping opportunities (these places can be reached through the Eskişehir Highway.) There is also the newly expanded ANKAmall at the outskirts, on the Istanbul Highway, which houses most of the well-known international brands. This mall is the largest throughout the Ankara region. In 2014 a few more shopping malls were open in Ankara. They are Next Level and Taurus on the Boulevard of Mevlana (also known as Konya Road). == Culture == === The arts === Turkish State Opera and Ballet, the national directorate of opera and ballet companies of Turkey, has its headquarters in Ankara, and serves the city with three venues: Ankara Opera House (Opera Sahnesi, also known as Büyük Tiyatro) is the largest of the three venues for opera and ballet in Ankara. ==== Music ==== Ankara is host to five classical music orchestras: Presidential Symphony Orchestra (Turkish Presidential Symphony Orchestra) Bilkent Symphony Orchestra (BSO) is a major symphony orchestra of Turkey.

It is a pleasant place to spend a day with family, be it for having picnics, hiking, biking or simply enjoying good food and nature. There is also an exact replica of the house where Atatürk was born in 1881, in Thessaloniki, Greece. Visitors to the "Çiftlik" (farm) as it is affectionately called by Ankarans, can sample such famous products of the farm such as old-fashioned beer and ice cream, fresh dairy products and meat rolls/kebaps made on charcoal, at a traditional restaurant (Merkez Lokantası, Central Restaurant), cafés and other establishments scattered around the farm. == Education == === Universities === Ankara is noted, within Turkey, for the multitude of universities it is home to. These include the following, several of them being among the most reputable in the country: == Fauna == === Angora cat === Ankara is home to a world-famous domestic cat breed – the Turkish Angora, called Ankara kedisi (Ankara cat) in Turkish. Turkish Angoras are one of the ancient, naturally occurring cat breeds, having originated in Ankara and its surrounding region in central Anatolia. They mostly have a white, silky, medium to long length coat, no undercoat and a fine bone structure. There seems to be a connection between the Angora Cats and Persians, and the Turkish Angora is also a distant cousin of the Turkish Van. Although they are known for their shimmery white coat, currently there are more than twenty varieties including black, blue and reddish fur. They come in tabby and tabby-white, along with smoke varieties, and are in every color other than pointed, lavender, and cinnamon (all of which would indicate breeding to an outcross.) Eyes may be blue, green, or amber, or even one blue and one amber or green. The W gene which is responsible for the white coat and blue eye is closely related to the hearing ability, and the presence of a blue eye can indicate that the cat is deaf to the side the blue eye is located. However, a great many blue and odd-eyed white cats have normal hearing, and even deaf cats lead a very normal life if kept indoors. Ears are pointed and large, eyes are almond shaped and the head is massive with a two plane profile. Another characteristic is the tail, which is often kept parallel to the back. === Angora rabbit === The Angora rabbit (Turkish: Ankara tavşanı) is a variety of domestic rabbit bred for its long, soft hair. The Angora is one of the oldest types of domestic rabbit, originating in Ankara and its surrounding region in central Anatolia, along with the Angora cat and Angora goat. The rabbits were popular pets with French royalty in the mid-18th century, and spread to other parts of Europe by the end of the century. They first appeared in the United States in the early 20th century. They are bred largely for their long Angora wool, which may be removed by shearing, combing, or plucking (gently pulling loose wool.) Angoras are bred mainly for their wool because it is silky and soft. They have a humorous appearance, as they oddly resemble a fur ball. Most are calm and docile but should be handled carefully. Grooming is necessary to prevent the fiber from matting and felting on the rabbit. A condition called "wool block" is common in Angora rabbits and should be treated quickly. Sometimes they are shorn in the summer as the long fur can cause the rabbits to overheat. === Angora goat === The Angora goat (Turkish: Ankara keçisi) is a breed of domestic goat that originated in Ankara and its surrounding region in central Anatolia.This breed was first mentioned in the time of Moses, roughly in 1500 BC. The first Angora goats were brought to Europe by Charles V, Holy Roman Emperor, about 1554, but, like later imports, were not very successful. Angora goats were first introduced in the United States in 1849 by Dr. James P. Davis. Seven adult goats were a gift from Sultan Abdülmecid I in appreciation for his services and advice on the raising of cotton. The fleece taken from an Angora goat is called mohair. A single goat produces between five and eight kilograms (11 and 18 pounds) of hair per year. Angoras are shorn twice a year, unlike sheep, which are shorn only once. Angoras have high nutritional requirements due to their rapid hair growth. A poor quality diet will curtail mohair development. The United States, Turkey, and South Africa are the top producers of mohair. For a long period of time, Angora goats were bred for their white coat. In 1998, the Colored Angora Goat Breeders Association was set up to promote breeding of colored Angoras. Today, Angora goats produce white, black (deep black to greys and silver), red (the color fades significantly as the goat gets older), and brownish fiber. Angora goats were depicted on the reverse of the Turkish 50 lira banknotes of 1938–1952. == Gallery == == International relations == === Twin towns and sister cities === Ankara is twinned with: === Partner cities === Skopje, Macedonia (since 1995) Vienna, Austria == See also == == Notes == == References == Baynes, T.S., ed.

### Instruction: retrieve labels for this: Sir Alfred Joseph Hitchcock, (13 August 1899 – 29 April 1980) was an English film director and producer, widely regarded as one of the most influential filmmakers in the history of cinema. Known as "the Master of Suspense", he directed over 50 feature films in a career spanning six decades, becoming as well-known as any of his actors thanks to his many interviews, his cameo roles in most of his films, and his hosting of Alfred Hitchcock Presents (1955–1965). Born on the outskirts of London, Hitchcock entered the film industry in 1919 as a title card designer after training as a technical clerk and copy writer for a telegraph-cable company. He made his directorial debut with The Pleasure Garden (1925). His first successful film, The Lodger: A Story of the London Fog (1927), helped to shape the thriller genre, while his 1929 film, Blackmail, was the first British "talkie". Two of his 1930s thrillers, The 39 Steps (1935) and The Lady Vanishes (1938), are ranked among the greatest British films of the 20th century. By 1939 Hitchcock was a filmmaker of international importance, and film producer David O. Selznick persuaded him to move to Hollywood. A string of successful films followed, including Rebecca (1940), Foreign Correspondent (1940), Shadow of a Doubt (1943), and The Paradine Case (1947); Rebecca was nominated for 11 Oscars and won the Academy Award for Best Picture. His fifty-three films have grossed over US$223.3 million worldwide and garnered a total of 46 Oscar nominations and 6 wins. The "Hitchcockian" style includes the use of camera movement to mimic a person's gaze, thereby turning viewers into voyeurs, and framing shots to maximise anxiety and fear. The film critic Robin Wood wrote that the meaning of a Hitchcock film "is there in the method, in the progression from shot to shot. A Hitchcock film is an organism, with the whole implied in every detail and every detail related to the whole." By 1960 Hitchcock had directed four films often ranked among the greatest of all time: Rear Window (1954), Vertigo (1958), North by Northwest (1959), and Psycho (1960); in 2012 Vertigo replaced Orson Welles's Citizen Kane (1941) as the British Film Institute's best film ever made. By 2016 seven of his films had been selected for preservation in the United States National Film Registry, including his personal favourite, Shadow of a Doubt (1943). He received the AFI Life Achievement Award in 1979 and was knighted in December that year, four months before he died. == Biography == === Early life: 1899–1919 === ==== Early childhood and education ==== Hitchcock was born in the flat above his parents' leased grocer's shop at 517 High Road, Leytonstone, on the outskirts of east London (then part of Essex), the youngest of three children: William (born 1890), Ellen Kathleen ("Nellie") (1892), and Alfred Joseph (1899). His parents, Emma Jane Hitchcock, née Whelan (1863–1942), and William Hitchcock (1862–1914), were both Roman Catholics, with partial roots in Ireland; William was a greengrocer as his father had been. There was a large extended family, including Uncle John Hitchcock with his five-bedroom Victorian house on Campion Road, Putney, complete with maid, cook, chauffeur and gardener. Every summer John rented a seaside house for the family in Cliftonville, Kent. Hitchcock said that he first became class-conscious there, noticing the differences between tourists and locals.Describing himself as a well-behaved boy—his father called him his "little lamb without a spot"—Hitchcock said he could not remember ever having had a playmate. One of his favourite stories for interviewers was about his father sending him to the local police station with a note when he was five; the policeman looked at the note and locked him in a cell for a few minutes, saying, "This is what we do to naughty boys." The experience left him, he said, with a lifelong fear of policemen; in 1973 he told Tom Snyder that he was "scared stiff of anything ... to do with the law" and wouldn't even drive a car in case he got a parking ticket.When he was six, the family moved to Limehouse and leased two stores at 130 and 175 Salmon Lane, which they ran as a fish-and-chips shop and fishmongers' respectively; they lived above the former. It seems that Hitchcock was seven when he attended his first school, the Howrah House Convent in Poplar, which he entered in 1907. According to Patrick McGilligan, he stayed at Howrah House for at most two years. He also attended a convent school, the Wode Street School "for the daughters of gentlemen and little boys", run by the Faithful Companions of Jesus; briefly attended a primary school near his home; and was for a very short time, when he was nine, a boarder at Salesian College in Battersea. The family moved again when he was 11, this time to Stepney, and on 5 October 1910 Hitchcock was sent to St Ignatius College in Stamford Hill, a Jesuit grammar school with a reputation for discipline. The priests used a hard rubber cane on the boys, always at the end of the day, so the boys had to sit through classes anticipating the punishment once they knew they'd been written up for it. He said it was here that he developed his sense of fear. The school register lists his year of birth as 1900 rather than 1899; Spoto writes that it seems he was deliberately enrolled as a 10-year-old, perhaps because he was a year behind with his schooling. While biographer Gene Adair reports that Hitchcock was "an average, or slightly above-average, pupil", Hitchcock said he was "usually among the four or five at the top of the class"; at the end of his first year, his work in Latin, English, French and religious education was noted. His favourite subject was geography, and he became interested in maps, and railway and bus timetables; according to Taylor, he could recite all the stops on the Orient Express. He told Peter Bogdanovich: "The Jesuits taught me organization, control and, to some degree, analysis." ==== Henley's ==== Hitchcock told his parents that he wanted to be an engineer, and on 25 July 1913, he left St Ignatius and enrolled in night classes at the London County Council School of Engineering and Navigation in Poplar. In a book-length interview in 1962, he told François Truffaut that he had studied "mechanics, electricity, acoustics, and navigation". Then on 12 December 1914 his father, who had been suffering from emphysema and kidney disease, died at the age of 52. To support himself and his mother—his older siblings had left home by then—Hitchcock took a job, for 15 shillings a week (£66 in 2017), as a technical clerk at the Henley Telegraph and Cable Company in Blomfield Street near London Wall. He kept up his night classes, this time in art history, painting, economics, and political science. His older brother ran the family shops, while he and his mother continued to live in Salmon Lane.He was too young to enlist when World War I broke out in July 1914, and when he was old enough, in 1917, he was classified as "C3" ("free from serious organic disease, able to stand service conditions in garrisons at home ... only suitable for sedentary work"). He joined a volunteer corps of the Royal Engineers and took part in theoretical briefings; there was one session of practical exercises in Hyde Park, during which, John Russell Taylor wrote, his puttees kept falling down around his ankles.After the war, Hitchcock began dabbling in creative writing. In June 1919 he became a founding editor and business manager of Henley's in-house publication, The Henley Telegraph (sixpence a copy), to which he submitted several short stories. Henley's promoted him to the advertising department, where he wrote copy and drew graphics for advertisements for electric cable. He apparently loved the job and would stay late at the office to examine the proofs; he told Truffaut that this was his "first step toward cinema". He enjoyed watching films, especially American cinema, and from the age of 16 read the trade papers; he watched Charlie Chaplin, D. W. Griffith and Buster Keaton, and particularly liked Fritz Lang's Der müde Tod (1921). === Inter-war career: 1919–1939 === ==== Famous Players-Lasky ==== While still at Henley's, he read in a trade paper that Famous Players-Lasky, the production arm of Paramount Pictures, was opening a studio in London. They were planning to film The Sorrows of Satan by Marie Corelli, so he produced some drawings for the title cards and sent his work to the studio. They hired him, and in 1919 he began working for Islington Studios in Poole Street, Hoxton, as a title-card designer. Donald Spoto writes that most of the staff were Americans with strict job specifications, but the English workers were encouraged to try their hand at anything, which meant that Hitchcock gained experience as a co-writer, art director and production manager on at least 18 silent films. The Times wrote in February 1922 about the studio's "special art title department under the supervision of Mr. A. J. Hitchcock". His work there included Number 13 (1922), also known as Mrs. Peabody, cancelled because of financial problems—the few finished scenes are lost—and Always Tell Your Wife (1923), which he and Seymour Hicks finished together when Hicks was about to give up on it. Hicks wrote later about being helped by "a fat youth who was in charge of the property room ... [n]one other than Alfred Hitchcock". ==== Gainsborough Pictures ==== When Paramount pulled out of London in 1922, Hitchcock was hired as an assistant director by a new firm run in the same location by Michael Balcon, later known as Gainsborough Pictures. Hitchcock worked on Woman to Woman (1923) with the director Graham Cutts, designing the set, writing the script and producing. He said: "It was the first film that I had really got my hands onto." The editor and "script girl" on Woman to Woman was Alma Reville, his future wife. He also worked as an assistant to Cutts on The White Shadow (1924), The Passionate Adventure (1924), The Blackguard (1925), and The Prude's Fall (1925). The Blackguard was produced at the Babelsberg Studios in Potsdam, where Hitchcock watched part of the making of F. W. Murnau's film The Last Laugh (1924). He was impressed with Murnau's work and later used many of his techniques for the set design in his own productions.In the summer of 1925, Balcon asked Hitchcock to direct The Pleasure Garden (1925), starring Virginia Valli, a co-production of Gainsborough and the German firm Emelka at the Geiselgasteig studio near Munich. Reville, by then Hitchcock's fiancée, was assistant director-editor. Although the film was a commercial flop, Balcon liked Hitchcock's work; a Daily Express headline called him, "Young man with a master mind". Balcon asked him to direct a second film in Munich, The Mountain Eagle (1926), released in the United States as Fear o' God. The film is lost; Hitchcock called it "a very bad movie".Hitchcock's luck changed with his first thriller, The Lodger: A Story of the London Fog (1927), about the hunt for a serial killer who, wearing a black cloak and carrying a black bag, is murdering young blonde women in London, and only on Tuesdays. A landlady suspects that her lodger is the killer, but he turns out to be innocent. To convey that footsteps were being heard from an upper floor, Hitchcock had a glass floor made so that the audience could see the lodger pacing up and down in his room above the landlady. Hitchcock had wanted the leading man to be guilty, or for the film at least to end ambiguously, but the star was Ivor Novello, a matinée idol, and the "star system" meant that Novello could not be the villain. Hitchcock told Truffaut: "You have to clearly spell it out in big letters: 'He is innocent.'" (He had the same problem years later with Cary Grant in Suspicion (1941).) Released in January 1927, The Lodger was a commercial and critical success in the UK. Hitchcock told Truffaut that the film was the first of his to be influenced by the Expressionist techniques he had witnessed in Germany: "In truth, you might almost say that The Lodger was my first picture." He made his first cameo appearances in the film, purely because an extra body was needed, sitting in a newsroom and later standing in a crowd as the leading man is arrested. ==== Marriage ==== On 2 December 1926, Hitchcock and Alma Reville (1899–1982) married at the Brompton Oratory in South Kensington. The couple honeymooned in Paris, Lake Como and St. Moritz, before returning to London to live in a leased flat on the top two floors of 153 Cromwell Road, Kensington. Reville, who was born just hours after Hitchcock, converted from Protestantism to Catholicism, apparently at the insistence of Hitchcock's mother; she was baptized on 31 May 1927 and confirmed at Westminster Cathedral by Cardinal Francis Bourne on 5 June. In 1928, when she learned that she was pregnant, the Hitchcocks purchased "Winter's Grace", a Tudor farmhouse set in 11 acres on Stroud Lane, Shamley Green, Surrey, for £2,500. Their daughter and only child, Patricia Alma Hitchcock, was born on 7 July that year. Reville became her husband's closest collaborator; Charles Champlin wrote in 1982: "The Hitchcock touch had four hands, and two were Alma's." ==== Early sound films ==== Hitchcock began work on his tenth film, Blackmail (1929), when its production company, British International Pictures (BIP), converted its Elstree studios to sound. The film was the first British "talkie"; it followed the first American sound feature film, The Jazz Singer (1927). Blackmail began the Hitchcock tradition of using famous landmarks as a backdrop for suspense sequences, with the climax taking place on the dome of the British Museum. It also features one of his longest cameo appearances, which shows him being bothered by a small boy as he reads a book on the London Underground. In the PBS series The Men Who Made The Movies, Hitchcock explained how he used early sound recording as a special element of the film, stressing the word "knife" in a conversation with the woman suspected of murder. During this period, Hitchcock directed segments for a BIP revue, Elstree Calling (1930), and directed a short film, An Elastic Affair (1930), featuring two Film Weekly scholarship winners. An Elastic Affair is one of the lost films.In 1933 Hitchcock was once again working for Michael Balcon at Gaumont British. His first film for the company, The Man Who Knew Too Much (1934), was a success; his second, The 39 Steps (1935), was acclaimed in the UK and made Hitchcock a star in the US. It also established the quintessential English "Hitchcock blonde" (Madeleine Carroll) as the template for his succession of ice-cold, elegant leading ladies. Screenwriter Robert Towne remarked, "It’s not much of an exaggeration to say that all contemporary escapist entertainment begins with The 39 Steps". This film was one of the first to introduce the "MacGuffin" plot device, a term coined by the English screenwriter Angus MacPhail. The MacGuffin is an item or goal the protagonist is pursuing, one that otherwise has no narrative value; in The 39 Steps, the MacGuffin is a stolen set of design plans. Hitchcock released two spy thrillers in 1936. Sabotage was loosely based on Joseph Conrad's novel, The Secret Agent (1907), about a woman who discovers that her husband is a terrorist, and Secret Agent, based on two stories in Ashenden: Or the British Agent (1928) by W. Somerset Maugham.Hitchcock's next major success was The Lady Vanishes (1938), "one of the greatest train movies from the genre's golden era", according to Philip French, in which Miss Froy (May Whitty), a British spy posing as a governess, disappears on a train journey through the fictional European country of Bandrika. The film saw Hitchcock receive the 1939 New York Film Critics Circle Award for Best Director, the only time he won an award for his direction. Benjamin Crisler, the New York Times film critic, wrote in June 1938: "Three unique and valuable institutions the British have that we in America have not: Magna Carta, the Tower Bridge and Alfred Hitchcock, the greatest director of screen melodramas in the world." === Early Hollywood years: 1939–1945 === ==== Selznick contract ==== David O. Selznick signed Hitchcock to a seven-year contract beginning in March 1939, and the Hitchcocks moved to Hollywood. In June that year Life magazine called him the "greatest master of melodrama in screen history". The working arrangements with Selznick were less than ideal. Selznick suffered from constant financial problems, and Hitchcock was often unhappy about Selznick's creative control over his films. In a later interview, Hitchcock said: "[Selznick] was the Big Producer. ... Producer was king. The most flattering thing Mr. Selznick ever said about me—and it shows you the amount of control—he said I was the 'only director' he'd 'trust with a film'." At the same time, Selznick complained about Hitchcock's "goddamn jigsaw cutting", which meant that the producer had to follow Hitchcock's vision of the finished product.Selznick lent Hitchcock to the larger studios more often than producing Hitchcock's films himself. Selznick made only a few films each year, as did fellow independent producer Samuel Goldwyn, so he did not always have projects for Hitchcock to direct. Goldwyn had also negotiated with Hitchcock on a possible contract, only to be outbid by Selznick. Hitchcock was quickly impressed by the superior resources of the American studios compared to the financial limits he had often faced in Britain. The Selznick picture Rebecca (1940) was Hitchcock's first American film, set in a Hollywood version of England's Cornwall and based on a novel by English novelist Daphne du Maurier. The film stars Laurence Olivier and Joan Fontaine. The story concerns a naïve (and unnamed) young woman who marries a widowed aristocrat. She goes to live in his huge English country house, and struggles with the lingering reputation of his elegant and worldly first wife Rebecca, who died under mysterious circumstances. The film won Best Picture at the 13th Academy Awards; the statuette was given to Selznick, as the film's producer. Hitchcock was nominated for Best Director, his first of five such nominations.Hitchcock's second American film was the thriller Foreign Correspondent (1940), set in Europe, based on Vincent Sheean's book Personal History (1935) and produced by Walter Wanger. It was nominated for Best Picture that year. Hitchcock felt uneasy living and working in Hollywood while his country was at war; his concern resulted in a film that overtly supported the British war effort. Filmed in the first year of World War II, it was inspired by the rapidly changing events in Europe, as covered by an American newspaper reporter played by Joel McCrea. Mixing footage of European scenes with scenes filmed on a Hollywood backlot, the film avoided direct references to Nazism, Nazi Germany, and Germans to comply with Hollywood's Motion Picture Production Code censorship at the time. ==== Early war years ==== In September 1940 the Hitchcocks bought the 200-acre (0.81 km2) Cornwall Ranch near Scotts Valley, California, in the Santa Cruz Mountains. Their primary residence was an English-style home in Bel Air, purchased in 1942. Hitchcock's films were diverse during this period, ranging from the romantic comedy Mr. & Mrs. Smith (1941) to the bleak film noir Shadow of a Doubt (1943). Suspicion (1941) marked Hitchcock's first film as a producer and director. It is set in England; Hitchcock used the north coast of Santa Cruz for the English coastline sequence. The film is the first of four projects on which Cary Grant worked with Hitchcock, and it is one of the rare occasions that Grant was cast in a sinister role. Grant plays Johnnie Aysgarth, an English con man whose actions raise suspicion and anxiety in his shy young English wife, Lina McLaidlaw (Joan Fontaine). In one scene Hitchcock placed a light inside a glass of milk, perhaps poisoned, that Grant is bringing to his wife; the light makes sure that the audience's attention is on the glass. Grant's character is a killer in the book on which the film was based, Before the Fact by Francis Iles, but the studio felt that Grant's image would be tarnished by that. Hitchcock therefore settled for an ambiguous finale, although, as he told François Truffaut, he would have preferred to end with the wife's murder. Fontaine won Best Actress for her performance.Saboteur (1942) is the first of two films that Hitchcock made for Universal during the decade. Hitchcock was forced by Universal Studios to use Universal contract player Robert Cummings and Priscilla Lane, a freelancer who signed a one-picture deal with Universal, both known for their work in comedies and light dramas. Breaking with Hollywood conventions of the time, Hitchcock did extensive location filming, especially in New York City, and depicted a confrontation between a suspected saboteur (Cummings) and a real saboteur (Norman Lloyd) atop the Statue of Liberty. He also directed Have You Heard? (1942), a photographic dramatisation for Life magazine of the dangers of rumours during wartime. In 1943 he wrote a mystery story for Look magazine, "The Murder of Monty Woolley", a sequence of captioned photographs inviting the reader to find clues to the murderer's identity; Hitchcock cast the performers as themselves, such as Woolley, Doris Merrick, and make-up man Guy Pearce. Shadow of a Doubt (1943) was Hitchcock's personal favourite and the second of the early Universal films. Charlotte "Charlie" Newton (Teresa Wright) suspects her beloved uncle Charlie Oakley (Joseph Cotten) of being a serial killer. Hitchcock again filmed extensively on location, this time in the Northern California city of Santa Rosa.Working at 20th Century Fox, Hitchcock adapted a script of John Steinbeck's, which recorded the experiences of the survivors of a German U-boat attack in the film Lifeboat (1944). The action sequences were shot in a small boat in the studio water tank. The locale posed problems for Hitchcock's traditional cameo appearance. That was solved by having Hitchcock's image appear in a newspaper that William Bendix is reading in the boat, showing the director in a before-and-after advertisement for "Reduco-Obesity Slayer". He told Truffaut in 1962: At the time, I was on a strenuous diet, painfully working my way from three hundred to two hundred pounds. So I decided to immortalize my loss and get my bit part by posing for "before" and "after" pictures. ... I was literally submerged by letters from fat people who wanted to know where and how they could get Reduco. Hitchcock's typical dinner before the weight loss had been a roast chicken, boiled ham, potatoes, bread, vegetables, relishes, salad, dessert, a bottle of wine and some brandy. To lose weight, he stopped drinking, drank black coffee for breakfast and lunch, and ate steak and salad for dinner, but it was hard to maintain; Spoto writes that his weight fluctuated considerably over the next 40 years. At the end of 1943, despite the weight loss, the Occidental Insurance Company of Los Angeles refused him life insurance. ==== Wartime non-fiction films ==== Hitchcock returned to the UK for an extended visit in late 1943 and early 1944. While there he made two short propaganda films, Bon Voyage (1944) and Aventure Malgache (1944), for the Ministry of Information. In June and July 1945 Hitchcock served as "treatment advisor" on a Holocaust documentary that used Allied Forces footage of the liberation of Nazi concentration camps. The film was assembled in London and produced by Sidney Bernstein of the Ministry of Information, who brought Hitchcock (a friend of his) on board. It was originally intended to be broadcast to the Germans, but the British government deemed it too traumatic to be shown to a shocked post-war population. Instead, it was transferred in 1952 from the British War Office film vaults to London's Imperial War Museum and remained unreleased until 1985, when an edited version was broadcast as an episode of PBS Frontline, under the title the Imperial War Museum had given it: Memory of the Camps. The full-length version of the film, German Concentration Camps Factual Survey, was restored in 2014 by scholars at the Imperial War Museum. === Post-war Hollywood years: 1945–1953 === ==== Later Selznick films ==== Hitchcock worked for David Selznick again when he directed Spellbound (1945), which explores psychoanalysis and features a dream sequence designed by Salvador Dalí. The dream sequence as it appears in the film is ten minutes shorter than was originally envisioned; Selznick edited it to make it "play" more effectively. Gregory Peck plays amnesiac Dr. Anthony Edwardes under the treatment of analyst Dr. Peterson (Ingrid Bergman), who falls in love with him while trying to unlock his repressed past. Two point-of-view shots were achieved by building a large wooden hand (which would appear to belong to the character whose point of view the camera took) and out-sized props for it to hold: a bucket-sized glass of milk and a large wooden gun. For added novelty and impact, the climactic gunshot was hand-coloured red on some copies of the black-and-white film. The original musical score by Miklós Rózsa makes use of the theremin, and some of it was later adapted by the composer into Rozsa's Piano Concerto Op. 31 (1967) for piano and orchestra.Notorious (1946) followed Spellbound. Hitchcock told François Truffaut that Selznick had sold him, Ingrid Bergman, Cary Grant, and the screenplay by Ben Hecht, to RKO Radio Pictures as a "package" for $500,000 (equivalent to $6,274,744 in 2017) because of cost overruns on Selznick's Duel in the Sun (1946). Notorious stars Bergman and Grant, both Hitchcock regulars, and features a plot about Nazis, uranium and South America. His prescient use of uranium as a plot device led to him being briefly placed under surveillance by the Federal Bureau of Investigation. According to McGilligan, in or around March 1945 Hitchcock and Ben Hecht consulted Robert Millikan of the California Institute of Technology about the development of a uranium bomb. Selznick complained that the notion was "science fiction", only to be confronted by the news of the detonation of two atomic bombs on Hiroshima and Nagasaki in Japan in August 1945. ==== Transatlantic Pictures ==== Hitchcock formed an independent production company, Transatlantic Pictures, with his friend Sidney Bernstein. He made two films with Transatlantic, one of which was his first colour film. With Rope (1948), Hitchcock experimented with marshalling suspense in a confined environment, as he had done earlier with Lifeboat (1944). The film appears to have been shot in a single take, but it was actually shot in 10 takes ranging from 4-½ to 10 minutes each; a 10-minute length of film was the most that a camera's film magazine could hold at the time. Some transitions between reels were hidden by having a dark object fill the entire screen for a moment. Hitchcock used those points to hide the cut, and began the next take with the camera in the same place. The film features James Stewart in the leading role, and was the first of four films that Stewart made with Hitchcock. It was inspired by the Leopold and Loeb case of the 1920s. The film was not well received.Under Capricorn (1949), set in 19th-century Australia, also uses the short-lived technique of long takes, but to a more limited extent. He again used Technicolor in this production, then returned to black-and-white films for several years. Transatlantic Pictures became inactive after these two unsuccessful films. Hitchcock filmed Stage Fright (1950) at studios in Elstree, England, where he had worked during his British International Pictures contract many years before. He matched one of Warner Bros.' most popular stars, Jane Wyman, with the expatriate German actor Marlene Dietrich and used several prominent British actors, including Michael Wilding, Richard Todd and Alastair Sim. This was Hitchcock's first proper production for Warner Bros., which had distributed Rope and Under Capricorn, because Transatlantic Pictures was experiencing financial difficulties.His film Strangers on a Train (1951) was based on the novel of the same name by Patricia Highsmith. Hitchcock combined many elements from his preceding films. He approached Dashiell Hammett to write the dialogue, but Raymond Chandler took over, then left over disagreements with the director. In the film, two men casually meet, one of whom speculates on a foolproof method to murder; he suggests that two people, each wishing to do away with someone, should each perform the other's murder. Farley Granger's role was as the innocent victim of the scheme, while Robert Walker, previously known for "boy-next-door" roles, played the villain. I Confess (1953) was set in Quebec with Montgomery Clift as a Catholic priest. === Peak years: 1954–1964 === ==== Dial M for Murder and Rear Window ==== I Confess was followed by three colour films starring Grace Kelly: Dial M for Murder (1954), Rear Window (1954), and To Catch a Thief (1955). In Dial M for Murder, Ray Milland plays the villain who tries to murder his unfaithful wife (Kelly) for her money. She kills the hired assassin in self-defence, so Milland manipulates the evidence to make it look like murder. Her lover, Mark Halliday (Robert Cummings), and Police Inspector Hubbard (John Williams) save her from execution. Hitchcock experimented with 3D cinematography for Dial M.Hitchcock moved to Paramount Pictures and filmed Rear Window (1954), starring James Stewart and Kelly again, as well as Thelma Ritter and Raymond Burr. Stewart's character is a photographer (based on Robert Capa) who must temporarily use a wheelchair. Out of boredom, he begins observing his neighbours across the courtyard, then becomes convinced that one of them (Raymond Burr) has murdered his wife. Stewart eventually manages to convince his policeman buddy (Wendell Corey) and his girlfriend (Kelly). As with Lifeboat and Rope, the principal characters are depicted in confined or cramped quarters, in this case Stewart's studio apartment. Hitchcock uses close-ups of Stewart's face to show his character's reactions, "from the comic voyeurism directed at his neighbours to his helpless terror watching Kelly and Burr in the villain's apartment". ==== Alfred Hitchcock Presents ==== From 1955 to 1965, Hitchcock was the host of the television series Alfred Hitchcock Presents. With his droll delivery, gallows humour and iconic image, the series made Hitchcock a celebrity. The title-sequence of the show pictured a minimalist caricature of his profile (he drew it himself; it is composed of only nine strokes), which his real silhouette then filled. The series theme tune was Funeral March of a Marionette by the French composer Charles Gounod (1818–1893).His introductions always included some sort of wry humour, such as the description of a recent multi-person execution hampered by having only one electric chair, while two are shown with a sign "Two chairs—no waiting!". He directed 18 episodes of the series, which aired from 1955 to 1965. It became The Alfred Hitchcock Hour in 1962, and NBC broadcast the final episode on 10 May 1965. In the 1980s, a new version of Alfred Hitchcock Presents was produced for television, making use of Hitchcock's original introductions in a colourised form. ==== From To Catch a Thief to Vertigo ==== In 1955 Hitchcock became a United States citizen. The same year, his third Grace Kelly film, To Catch a Thief, was released; it is set in the French Riviera, and pairs Kelly with Cary Grant. Grant plays retired thief John Robie, who becomes the prime suspect for a spate of robberies in the Riviera. A thrill-seeking American heiress played by Kelly surmises his true identity and tries to seduce him. "Despite the obvious age disparity between Grant and Kelly and a lightweight plot, the witty script (loaded with double entendres) and the good-natured acting proved a commercial success." It was Hitchcock's last film with Kelly. She married Prince Rainier of Monaco in 1956, and ended her film career. Hitchcock then remade his own 1934 film The Man Who Knew Too Much in 1956. This time, the film starred James Stewart and Doris Day, who sang the theme song "Que Sera, Sera", which won the Oscar for Best Original Song and became a big hit for her. They play a couple whose son is kidnapped to prevent them from interfering with an assassination. As in the 1934 film, the climax takes place at the Royal Albert Hall, London.The Wrong Man (1957), Hitchcock's final film for Warner Bros., is a low-key black-and-white production based on a real-life case of mistaken identity reported in Life magazine in 1953. This was the only film of Hitchcock to star Henry Fonda, playing a Stork Club musician mistaken for a liquor store thief, who is arrested and tried for robbery while his wife (Vera Miles) emotionally collapses under the strain. Hitchcock told Truffaut that his lifelong fear of the police attracted him to the subject and was embedded in many scenes. Hitchcock's next film, Vertigo (1958) again starred James Stewart, this time with Kim Novak and Barbara Bel Geddes. He had wanted Vera Miles to play the lead, but she was pregnant. He told Oriana Fallaci: "I was offering her a big part, the chance to become a beautiful sophisticated blonde, a real actress. We’d have spent a heap of dollars on it, and she has the bad taste to get pregnant. I hate pregnant women, because then they have children."In the film, James Stewart plays Scottie, a former police investigator suffering from acrophobia, who develops an obsession with a woman he has been hired to shadow (Kim Novak). Scottie's obsession leads to tragedy, and this time Hitchcock does not opt for a happy ending. Some critics, including Donald Spoto and Roger Ebert, agree that Vertigo is the director's most personal and revealing film, dealing with the Pygmalion-like obsessions of a man who crafts a woman into the woman he desires. Vertigo explores more frankly and at greater length his interest in the relation between sex and death than any other work in his filmography.Vertigo contains a camera technique developed by Irmin Roberts, commonly referred to as a dolly zoom, that has been copied many times by filmmakers. The film premiered at the San Sebastián International Film Festival, where Hitchcock won a Silver Seashell. Vertigo is considered a classic, but it attracted some negative reviews and poor box-office receipts at the time, and it was the last collaboration between Stewart and Hitchcock. In the 2002 Sight & Sound polls, it ranked just behind Citizen Kane (1941); ten years later, in the same magazine, critics chose it as the best film ever made. ==== North by Northwest and Psycho ==== Hitchcock followed Vertigo with three more successful films, which are also recognised as among his best: North by Northwest (1959), Psycho (1960) and The Birds (1963). In North by Northwest, Cary Grant portrays Roger Thornhill, a Madison Avenue advertising executive who is mistaken for a government secret agent. He is hotly pursued across the United States by enemy agents, including (it appears) Eve Kendall (Eva Marie Saint). Thornhill at first believes Kendall is helping him, then that she is an enemy agent; he eventually learns that she is working undercover for the CIA. During its opening two-week run at Radio City Music Hall, the film grossed $404,056 (equivalent to $3,392,041 in 2017), setting a record in that theatre's non-holiday gross. Time magazine called the film "smoothly troweled and thoroughly entertaining". Psycho (1960) is arguably Hitchcock's best-known film. Based on Robert Bloch's novel Psycho (1959), which was inspired by the case of Ed Gein, the film was produced on a constrained budget of $800,000 (equivalent to $6,617,773 in 2017) and shot in black-and-white on a spare set using crew members from Alfred Hitchcock Presents. The unprecedented violence of the shower scene, the early death of the heroine, and the innocent lives extinguished by a disturbed murderer became the hallmarks of a new horror-film genre. The public loved the film, with lines stretching outside cinemas as people had to wait for the next showing. It broke box-office records in the United Kingdom, France, South America, the United States and Canada and was a moderate success in Australia for a brief period.The film was the most profitable of Hitchcock's career; he personally earned well in excess of $15 million (equivalent to $124.08 million in 2017). He subsequently swapped his rights to Psycho and his TV anthology for 150,000 shares of MCA, making him the third largest shareholder and his own boss at Universal, in theory at least, although that did not stop them from interfering with him. Following the first film, Psycho became an American horror franchise: Psycho II, Psycho III, Bates Motel, Psycho IV: The Beginning, and a colour 1998 remake of the original. ==== Truffaut interview ==== On 13 August 1962, Hitchcock's 63rd birthday, the French director François Truffaut began a 50-hour interview of Hitchcock, filmed over eight days at Universal Studios, during which Hitchcock agreed to answer 500 questions. It took four years to transcribe the tapes and organize the images; it was published as a book in 1967 (the "hitchbook", as Truffaut called it), and the footage was released as a documentary in 2015. Truffaut sought the interview because it was clear to him that Hitchcock was not simply the entertainer the American media made him out to be. It was obvious from his films, Truffaut wrote, that Hitchcock had "given more thought to the potential of his art than any of his colleagues". He compared the interview to "Oedipus' consultation of the oracle". ==== The Birds ==== The film scholar Peter William Evans writes that The Birds (1963) and Marnie (1964) are regarded as "undisputed masterpieces". Hitchcock had intended to film Marnie first, and in March 1962 it was announced that Grace Kelly, Princess Grace of Monaco since 1956, would come out of retirement to star in it. When Kelly asked Hitchcock to postpone Marnie until 1963 or 1964, he recruited Evan Hunter, author of The Blackboard Jungle (1954), to develop a screenplay based on a Daphne du Maurier short story, "The Birds" (1952), which Hitchcock had republished in his My Favorites in Suspense (1959). He hired Tippi Hedren to play the lead role. It was her first role; she had been a model in New York when Hitchcock saw her, in October 1961, in an NBC television ad for Sego, a diet drink: "I signed her because she is a classic beauty. Movies don't have them any more. Grace Kelly was the last." He insisted, without explanation, that her first name be written in single quotation marks: 'Tippi'.In The Birds, Melanie Daniels, a young socialite, meets lawyer Mitch Brenner (Rod Taylor) in a bird shop; Jessica Tandy plays his possessive mother. Hedren visits him in Bodega Bay (where The Birds was filmed) carrying a pair of lovebirds as a gift. Suddenly waves of birds start gathering, watching, and attacking. The question: "What do the birds want?" is left unanswered. Hitchcock made the film with equipment from the Revue Studio, which made Alfred Hitchcock Presents. He said it was his most technically challenging film yet, using a combination of trained and mechanical birds against a backdrop of wild ones. Every shot was sketched in advance.An HBO/BBC television film, The Girl (2012), depicted Hedren's experiences on set; she said that Hitchcock became obsessed with her and sexually harassed her. He reportedly isolated her from the rest of the crew, had her followed, whispered obscenities to her, had her handwriting analysed, and had a ramp built from his private office directly into her trailer. Diane Baker, her co-star in Marnie, said: "[N]othing could have been more horrible for me than to arrive on that movie set and to see her being treated the way she was." While filming the attack scene in the attic—which took a week to film—she was placed in a caged room while two men wearing elbow-length protective gloves threw live birds at her. Toward the end of the week, to stop the birds flying away from her too soon, one leg of each bird was attached by nylon thread to elastic bands sewn inside her clothes. She broke down after a bird cut her lower eyelid, and filming was halted on doctor's orders. ==== Marnie ==== In June 1962, Grace Kelly announced that she had decided against appearing in Marnie (1964). Hedren had signed an exclusive seven-year, $500-a-week contract with him in October 1961, and he decided to cast her in the lead role opposite Sean Connery. In 2016, describing Hedren's performance as "one of the greatest in the history of cinema", Richard Brody called the film a "story of sexual violence" inflicted on the character played by Hedren: "The film is, to put it simply, sick, and it's so because Hitchcock was sick. He suffered all his life from furious sexual desire, suffered from the lack of its gratification, suffered from the inability to transform fantasy into reality, and then went ahead and did so virtually, by way of his art." A 1964 New York Times film review called it Hitchcock's "most disappointing film in years", citing Hedren's and Connery's lack of experience, an amateurish script and "glaringly fake cardboard backdrops".In the film, Marnie Edgar (Hedren) steals $10,000 (equivalent to $78,906 in 2017) from her employer and goes on the run. She applies for a job at Mark Rutland's (Connery) company in Philadelphia and steals from there too. Earlier she is shown having a panic attack during a thunderstorm and fearing the colour red. Mark tracks her down and blackmails her into marrying him. She explains that she does not want to be touched, but during the "honeymoon", Mark rapes her. Marnie and Mark discover that Marnie's mother had been a prostitute when Marnie was a child, and that, while the mother was fighting with a client during a thunderstorm—the mother believed the client had tried to molest Marnie—Marnie had killed the client to save her mother. Cured of her fears when she remembers what happened, she decides to stay with Mark. No longer speaking to her because she had rebuffed him, Hitchcock apparently referred to Hedren throughout as "the girl" rather than by name. He told Robert Burks, the cinematographer, that the camera had to be placed as close as possible to Hedren when he filmed her face. Evan Hunter, the screenwriter of The Birds who was writing Marnie too, explained to Hitchcock that, if Mark loved Marnie, he would comfort her, not rape her. Hitchcock reportedly replied: "Evan, when he sticks it in her, I want that camera right on her face!" When Hunter submitted two versions of the script, one without the rape scene, Hitchcock replaced him with Jay Presson Allen. === Later years: 1966–1980 === ==== Final films ==== Failing health reduced Hitchcock's output during the last two decades of his life. Biographer Stephen Rebello claimed Universal "forced" two movies on him, Torn Curtain (1966) and Topaz (1969). Both were spy thrillers with Cold War-related themes. Torn Curtain, with Paul Newman and Julie Andrews, precipitated the bitter end of the 12-year collaboration between Hitchcock and composer Bernard Herrmann. Hitchcock was unhappy with Herrmann's score and replaced him with John Addison, Jay Livingston and Ray Evans. Topaz (1967), based on a Leon Uris novel, is partly set in Cuba. Both films received mixed reviews. Hitchcock returned to Britain to make his penultimate film, Frenzy (1972), based on the novel Goodbye Piccadilly, Farewell Leicester Square (1966). After two espionage films, the plot marked a return to the murder-thriller genre. Richard Blaney (Jon Finch), a volatile barman with a history of explosive anger, becomes the prime suspect in the investigation into the "Necktie Murders", which are actually committed by his friend Bob Rusk (Barry Foster). This time, Hitchcock makes the victim and villain kindreds, rather than opposites as in Strangers on a Train.In Frenzy, Hitchcock allowed nudity for the first time. Two scenes show naked women, one of whom is being raped and strangled; Spoto called the latter "one of the most repellent examples of a detailed murder in the history of film". Both actors, Barbara Leigh-Hunt and Anna Massey, refused to do the scenes, so models were used instead. Biographers have noted that Hitchcock had always pushed the limits of film censorship, often managing to fool Joseph Breen, the longtime head of Hollywood's Motion Picture Production Code. Many times Hitchcock slipped in subtle hints of improprieties forbidden by censorship until the mid-1960s. Yet McGilligan wrote that Breen and others often realised that Hitchcock was inserting such things and were actually amused, as well as alarmed by Hitchcock's "inescapable inferences".Family Plot (1976) was Hitchcock's last film. It relates the escapades of "Madam" Blanche Tyler, played by Barbara Harris, a fraudulent spiritualist, and her taxi-driver lover Bruce Dern, making a living from her phony powers. While Family Plot was based on the Victor Canning novel The Rainbird Pattern (1972), the novel's tone is more sinister. Screenwriter Ernest Lehman originally wrote the film with a dark tone but was pushed to a lighter, more comical tone by Hitchcock. ==== Knighthood and death ==== Toward the end of his life, Hitchcock was working on the script for a spy thriller, The Short Night, collaborating with James Costigan, Ernest Lehman and David Freeman. Despite preliminary work, it was never filmed. Hitchcock's health was declining and he was worried about his wife, who had suffered a stroke. The screenplay was eventually published in Freeman's book The Last Days of Alfred Hitchcock (1999).Having refused a CBE in 1962, Hitchcock was appointed a Knight Commander of the Most Excellent Order of the British Empire (KBE) in the 1980 New Year Honours. He was too ill to travel to London—he had a pacemaker and was being given cortisone injections for his arthritis—so on 3 January 1980 the British consul general presented him with the papers at Universal Studios. Asked by a reporter after the ceremony why it had taken the Queen so long, Hitchcock quipped, "I suppose it was a matter of carelessness." Cary Grant, Janet Leigh, and others attended a luncheon afterwards.His last public appearance was on 16 March 1980, when he introduced the next year's winner of the American Film Institute award. He died of renal failure the following month, on 29 April, in his Bel Air home. Donald Spoto, one of Hitchcock's biographers, wrote that Hitchcock had declined to see a priest, but according to Jesuit priest Mark Henninger, he and another priest, Tom Sullivan, celebrated Mass at the filmmaker's home, and Sullivan heard his confession. Hitchcock was survived by his wife and daughter. His funeral was held at Good Shepherd Catholic Church in Beverly Hills on 30 April, after which his body was cremated. His remains were scattered over the Pacific Ocean on 10 May 1980. == Filmmaking == === Themes and motifs === Hitchcock returned several times to cinematic devices such as the audience as voyeur, suspense, the wrong man or woman, and the "MacGuffin," a plot device essential to the characters but irrelevant to the audience. Thus, the MacGuffin was always hazily described (in North by Northwest, Leo G. Carroll describes James Mason as an "importer-exporter"). Hitchcock appears briefly in most of his own films. For example, he is seen struggling to get a double bass onto a train (Strangers on a Train), walking dogs out of a pet shop (The Birds), fixing a neighbour's clock (Rear Window), as a shadow (Family Plot), sitting at a table in a photograph (Dial M for Murder), and missing a bus (North by Northwest). === Representation of women === Hitchcock's portrayal of women has been the subject of much scholarly debate. Bidisha wrote in The Guardian in 2010: "There's the vamp, the tramp, the snitch, the witch, the slink, the double-crosser and, best of all, the demon mommy. Don't worry, they all get punished in the end." In a widely cited essay in 1975, Laura Mulvey introduced the idea of the male gaze; the view of the spectator in Hitchcock's films, she argued, is that of the heterosexual male protagonist. "The female characters in his films reflected the same qualities over and over again," Roger Ebert wrote in 1996. "They were blonde. They were icy and remote. They were imprisoned in costumes that subtly combined fashion with fetishism. They mesmerised the men, who often had physical or psychological handicaps. Sooner or later, every Hitchcock woman was humiliated." The victims in The Lodger are all blondes. In The 39 Steps (1935), Madeleine Carroll is put in handcuffs. Ingrid Bergman, whom Hitchcock directed three times (Spellbound (1945), Notorious (1946), and Under Capricorn (1949)), is dark blonde. In Rear Window (1954), Lisa (Grace Kelly) risks her life by breaking into Lars Thorwald's apartment. In To Catch a Thief (1955), Francie (Grace Kelly again) offers to help a man she believes is a burglar. In Vertigo (1958) and North by Northwest (1959) respectively, Kim Novak and Eva Marie Saint play the blonde heroines. In Psycho (1960), Janet Leigh's character steals $40,000 (equivalent to $330,889 in 2017) and is murdered by Norman Bates, a reclusive psychopath. Tippi Hedren, a blonde, appears to be the focus of the attacks in The Birds (1963). In Marnie (1964), the title character, again played by Hedren, is a thief. In Topaz, French actresses Dany Robin as Stafford's wife and Claude Jade as Stafford's daughter are blonde heroines, the mistress was played by brunette Karin Dor. Hitchcock's last blonde heroine was Barbara Harris as a phony psychic turned amateur sleuth in Family Plot (1976), his final film. In the same film, the diamond smuggler played by Karen Black wears a long blonde wig in several scenes. His films often feature characters struggling in their relationships with their mothers, such as Norman Bates in Psycho. In North by Northwest (1959), Roger Thornhill (Cary Grant) is an innocent man ridiculed by his mother for insisting that shadowy, murderous men are after him. In The Birds (1963), the Rod Taylor character, an innocent man, finds his world under attack by vicious birds, and struggles to free himself from a clinging mother (Jessica Tandy). The killer in Frenzy (1972) has a loathing of women but idolises his mother. The villain Bruno in Strangers on a Train hates his father, but has an incredibly close relationship with his mother (played by Marion Lorne). Sebastian (Claude Rains) in Notorious has a clearly conflicting relationship with his mother, who is (rightly) suspicious of his new bride, Alicia Huberman (Ingrid Bergman). === Relationship with actors === Hitchcock became known for having remarked that "actors are cattle." During the filming of Mr. & Mrs. Smith (1941), Carole Lombard brought three cows onto the set wearing the name tags of Lombard, Robert Montgomery, and Gene Raymond, the stars of the film, to surprise him.Hitchcock believed that actors should concentrate on their performances and leave work on script and character to the directors and screenwriters. He told Bryan Forbes in 1967: "I remember discussing with a method actor how he was taught and so forth. He said, 'We're taught using improvisation. We are given an idea and then we are turned loose to develop in any way we want to.' I said 'That's not acting. That's writing.'" Walter Slezak said that Hitchcock knew the mechanics of acting better than anyone he knew.Critics observed that, despite his reputation as a man who disliked actors, actors who worked with him often gave brilliant performances. He used the same actors in many of his films; Cary Grant worked with Hitchcock four times, and Ingrid Bergman three. James Mason said that Hitchcock regarded actors as "animated props". For Hitchcock, the actors were part of the film's setting. He told François Truffaut: "[T]he chief requisite for an actor is the ability to do nothing well, which is by no means as easy as it sounds. He should be willing to be utilised and wholly integrated into the picture by the director and the camera. He must allow the camera to determine the proper emphasis and the most effective dramatic highlights." === Writing, storyboards and production === Hitchcock planned his scripts in detail with his writers. In Writing with Hitchcock (2001), Steven DeRosa noted that Hitchcock supervised them through every draft, asking that they tell the story visually. He told Roger Ebert in 1969: Once the screenplay is finished, I'd just as soon not make the film at all. All the fun is over. I have a strongly visual mind. I visualize a picture right down to the final cuts. I write all this out in the greatest detail in the script, and then I don't look at the script while I'm shooting. I know it off by heart, just as an orchestra conductor needs not look at the score. It's melancholy to shoot a picture. When you finish the script, the film is perfect. But in shooting it you lose perhaps 40 per cent of your original conception. Hitchcock's films were extensively storyboarded to the finest detail. He was reported to have never even bothered looking through the viewfinder, since he did not need to, although in publicity photos he was shown doing so. He also used this as an excuse to never have to change his films from his initial vision. If a studio asked him to change a film, he would claim that it was already shot in a single way, and that there were no alternate takes to consider. This view of Hitchcock as a director who relied more on pre-production than on the actual production itself has been challenged by Bill Krohn, the American correspondent of French film magazine Cahiers du cinéma, in his book Hitchcock at Work. After investigating script revisions, notes to other production personnel written by or to Hitchcock, and other production material, Krohn observed that Hitchcock's work often deviated from how the screenplay was written or how the film was originally envisioned. He noted that the myth of storyboards in relation to Hitchcock, often regurgitated by generations of commentators on his films, was to a great degree perpetuated by Hitchcock himself or the publicity arm of the studios. For example, the celebrated crop-spraying sequence of North by Northwest was not storyboarded at all. After the scene was filmed, the publicity department asked Hitchcock to make storyboards to promote the film, and Hitchcock in turn hired an artist to match the scenes in detail.Even when storyboards were made, scenes that were shot differed from them significantly. Krohn's analysis of the production of Hitchcock classics like Notorious reveals that Hitchcock was flexible enough to change a film's conception during its production. Another example Krohn notes is the American remake of The Man Who Knew Too Much, whose shooting schedule commenced without a finished script and moreover went over schedule, something that, as Krohn notes, was not an uncommon occurrence on many of Hitchcock's films, including Strangers on a Train and Topaz. While Hitchcock did do a great deal of preparation for all his films, he was fully cognisant that the actual film-making process often deviated from the best-laid plans and was flexible to adapt to the changes and needs of production as his films were not free from the normal hassles faced and common routines utilised during many other film productions. Krohn's work also sheds light on Hitchcock's practice of generally shooting in chronological order, which he notes sent many films over budget and over schedule and, more importantly, differed from the standard operating procedure of Hollywood in the Studio System Era. Equally important is Hitchcock's tendency to shoot alternate takes of scenes. This differed from coverage in that the films were not necessarily shot from varying angles so as to give the editor options to shape the film how he/she chooses (often under the producer's aegis). Rather they represented Hitchcock's tendency to give himself options in the editing room, where he would provide advice to his editors after viewing a rough cut of the work. According to Krohn, this and a great deal of other information revealed through his research of Hitchcock's personal papers, script revisions and the like refute the notion of Hitchcock as a director who was always in control of his films, whose vision of his films did not change during production, which Krohn notes has remained the central long-standing myth of Alfred Hitchcock. Both his fastidiousness and attention to detail also found their way into each film poster for his films. Hitchcock preferred to work with the best talent of his day—film poster designers such as Bill Gold and Saul Bass—who would produce posters that accurately represented his films. == Legacy == === Awards and honours === Hitchcock was inducted into the Hollywood Walk of Fame on 8 February 1960 with two stars, one for television and a second for his motion pictures. In 1978 John Russell Taylor described him as "the most universally recognizable person in the world" and "a straightforward middle-class Englishman who just happened to be an artistic genius". In 2002 MovieMaker named him the most influential director of all time, and a 2007 The Daily Telegraph critics' poll ranked him Britain's greatest director. David Gritten, the newspaper's film critic, wrote: "Unquestionably the greatest filmmaker to emerge from these islands, Hitchcock did more than any director to shape modern cinema, which would be utterly different without him." He won two Golden Globes, eight Laurel Awards, and five lifetime achievement awards, including the first BAFTA Academy Fellowship Award and, in 1979, an AFI Life Achievement Award. He was nominated five times for an Academy Award for Best Director. Rebecca, nominated for 11 Oscars, won the Academy Award for Best Picture of 1940; another Hitchcock film, Foreign Correspondent, was also nominated that year. By 2016 seven of his films had been selected for preservation by the United States National Film Registry: Shadow of a Doubt (1943), Notorious (1946), Rear Window (1954), Vertigo (1958), North by Northwest (1959), Psycho (1960), and The Birds (1963).In 2012 Hitchcock was selected by artist Sir Peter Blake, author of the Beatles' Sgt. Pepper's Lonely Hearts Club Band album cover, to appear in a new version of the cover, along with other British cultural figures, and he was featured that year in a BBC Radio 4 series, The New Elizabethans, as someone "whose actions during the reign of Elizabeth II have had a significant impact on lives in these islands and given the age its character". In June 2013 nine restored versions of Hitchcock's early silent films, including The Pleasure Garden (1925), were shown at the Brooklyn Academy of Music's Harvey Theatre; known as "The Hitchcock 9", the travelling tribute was organised by the British Film Institute. === Archives === The Alfred Hitchcock Collection is housed at the Academy Film Archive in Hollywood, California. It includes home movies, 16 mm film shot on the set of Blackmail (1929) and Frenzy (1972), and the earliest known colour footage of Hitchcock. The Academy Film Archive preserves many of his home movies. The Alfred Hitchcock Papers is housed at the Academy's Margaret Herrick Library. The David O. Selznick and the Ernest Lehman collections housed at the Harry Ransom Humanities Research Center in Austin, Texas, contain material related to Hitchcock's work on the production of The Paradine Case, Rebecca, Spellbound, North by Northwest and Family Plot. === Hitchcock portrayals === Anthony Hopkins in Hitchcock (2012) Toby Jones in The Girl (2012) Roger Ashton-Griffiths in Grace of Monaco (2014) == Filmography == === Films === === Frequently cast actors === == See also == List of Alfred Hitchcock cameo appearances List of film director and actor collaborations List of unproduced Hitchcock projects == Notes and sources == === Notes === === References === === Works cited === Biographies (chronological) Miscellaneous == Further reading == == External links == Alfred Hitchcock at the BFI Alfred Hitchcock on IMDb Alfred Hitchcock at AllMovie Alfred Hitchcock at the TCM Movie Database Alfred Hitchcock at the British Film Institute's Screenonline Alfred Hitchcock papers at the Margaret Herrick Library Talking About Alfred Hitchcock at The Interviews: An Oral History of Television Alfred Hitchcock at Find a Grave ### Answer: <1899 births>, <1980 deaths>, <19th-century English people>, <Alfred Hitchcock>, <American film directors>, <American film producers>, <American television directors>, <BAFTA fellows>, <Cecil B.

### Instruction: retrieve labels for this: Anacondas are a group of large snakes of the genus Eunectes. They are found in tropical South America. Four species are currently recognized. == Description == Although the name applies to a group of snakes, it is often used to refer only to one species in particular, the common or green anaconda (Eunectes murinus) which is the largest snake in the world by weight, and the second longest. == Etymology == The South American names anacauchoa and anacaona were suggested in an account by Peter Martyr d'Anghiera but the idea of a South American origin was questioned by Henry Walter Bates who, in his travels in South America, failed to find any similar name in use. The word anaconda is derived from the name of a snake from Ceylon (Sri Lanka) that John Ray described in Latin in his Synopsis Methodica Animalium (1693) as serpens indicus bubalinus anacandaia zeylonibus, ides bubalorum aliorumque jumentorum membra conterens. Ray used a catalogue of snakes from the Leyden museum supplied by Dr. Tancred Robinson, but the description of its habit was based on Andreas Cleyer who in 1684 described a gigantic snake that crushed large animals by coiling and crushing their bones. Henry Yule in his Hobson-Jobson notes that the word became more popular due to a piece of fiction published in 1768 in the Scots Magazine by a certain R. Edwin. Edwin described a 'tiger' being crushed and killed by an anaconda, when in fact tigers never occurred in Sri Lanka. Yule and Frank Wall noted that the snake was in fact a python and suggested a Tamil origin anai-kondra meaning elephant killer. A Sinhalese origin was also suggested by Donald Ferguson who pointed out that the word Henakandaya (hena lightning/large and kanda stem/trunk) was used in Sri Lanka for the small whip snake (Ahaetulla pulverulenta) and somehow got misapplied to the python before myths were created.The name commonly used for the anaconda in Brazil is sucuri, sucuriju or sucuriuba. == Species and other uses of the term "anaconda" == The term "anaconda" has been used to refer to: Any member of the genus Eunectes, a group of large, aquatic snakes found in South America: Eunectes murinus, the green anaconda – the largest species, found east of the Andes in Colombia, Venezuela, the Guianas, Ecuador, Peru, Bolivia, Brazil and Trinidad and Tobago Eunectes notaeus, the yellow anaconda – a small species, found in eastern Bolivia, southern Brazil, Paraguay and northeastern Argentina Eunectes deschauenseei, the darkly-spotted anaconda – a rare species, found in northeastern Brazil and coastal French Guiana Eunectes beniensis, the Bolivian anaconda – the most recently defined species, found in the Departments of Beni and Pando in Bolivia The giant anaconda, a mythical snake of enormous proportions said to be found in South America The term was previously applied imprecisely, indicating any large snake that constricts its prey, though this usage is now archaic. == See also == South American jaguar, a competitor or predator == Notes == == References == == Further reading == ### Answer: <Boinae by common name>, <Set indices on snakes>, <Snakes>

### Instruction: retrieve labels for this: Austrian German (German: Österreichisches Deutsch), Austrian Standard German, Standard Austrian German (German: Österreichisches Standarddeutsch) or Austrian High German (German: Österreichisches Hochdeutsch), is the variety of Standard German written and spoken in Austria. It has the highest sociolinguistic prestige locally, as it is the variation used in the media and for other formal situations. In Germany, however, Standard Austrian German is still confused with some regional standard that is not considered "pure".. This despite sound evidence that 80% of Austrian high school students and 90% of Austrian high school teachers consider German a pluricentric language, with more than one standard variety.In less formal situations, Austrians tend to use forms closer to or identical with the Bavarian and Alemannic dialects, traditionally spoken – but rarely written – in Austria. == History == Austrian German has its beginning in the mid-18th century, when empress Maria Theresa and her son Joseph II introduced compulsory schooling (in 1774) and several reforms of administration in their multilingual Habsburg empire. At the time, the written standard was Oberdeutsche Schreibsprache, which was highly influenced by the Bavarian and Alemannic dialects of Austria. Another option was to create a new standard based on the Southern German dialects, as proposed by the linguist Johann Siegmund Popowitsch. Instead they decided for pragmatic reasons to adopt the already standardized Chancellery language of Saxony (Sächsische Kanzleisprache or Meißner Kanzleideutsch), which was based on the administrative language of the non-Austrian area of Meißen and Dresden. Thus Standard Austrian German has the same geographic origin as the Standard German of Germany (Bundesdeutsches Hochdeutsch, also Deutschländisches Deutsch) and Swiss High German (Schweizer Hochdeutsch, not to be confused with the Alemannic Swiss German dialects). The process of introducing the new written standard was led by Joseph von Sonnenfels. Since 1951 the standardized form of Austrian German for official texts and schools is defined by the Austrian Dictionary (Österreichisches Wörterbuch), published under the authority of the Austrian Federal Ministry of Education, Arts and Culture. == General situation of German == As German is a pluricentric language, Austrian German is merely one among several varieties of Standard German. Much like the relationship between British English and American English, the German varieties differ in minor respects (e.g., spelling, word usage and grammar) but are recognizably equivalent and largely mutually intelligible. == Standard German in Austria == The official Austrian dictionary, das Österreichische Wörterbuch, prescribes grammatical and spelling rules defining the official language. Austrian delegates participated in the international working group that drafted the German spelling reform of 1996—several conferences leading up to the reform were hosted in Vienna at the invitation of the Austrian federal government—and adopted it as a signatory, along with Germany, Switzerland, and Liechtenstein, of an international memorandum of understanding (Wiener Absichtserklärung) signed in Vienna in 1996. The "sharp s" (ß) is used in Austria, as in Germany. Because of the German language's pluricentric nature, German dialects in Austria should not be confused with the variety of Standard German spoken by most Austrians, which is distinct from that of Germany or Switzerland. Distinctions in vocabulary persist, for example, in culinary terms, where communication with Germans is frequently difficult, and administrative and legal language, which is due to Austria's exclusion from the development of a German nation-state in the late 19th century and its manifold particular traditions. A comprehensive collection of Austrian-German legal, administrative and economic terms is offered in Markhardt, Heidemarie: Wörterbuch der österreichischen Rechts-, Wirtschafts- und Verwaltungsterminologie (Peter Lang, 2006). === Former spoken standard === The "former standard", used for about 300 years or more in speech in refined language, was the Schönbrunner Deutsch, a sociolect spoken by the imperial Habsburg family and the nobility of Austria-Hungary. It differed from other dialects in vocabulary and pronunciation; it appears to have been spoken with a slight degree of nasality. This was not a standard in a modern technical sense, as it was just the social standard of upper-class speech. === Special written forms === For many years, Austria had a special form of the language for official government documents. This form is known as Österreichische Kanzleisprache, or "Austrian chancellery language". It is a very traditional form of the language, probably derived from medieval deeds and documents, and has a very complicated structure and vocabulary generally reserved for such documents. For most speakers (even native speakers), this form of the language is generally difficult to understand, as it contains many highly specialised terms for diplomatic, internal, official, and military matters. There are no regional variations, because this special written form has mainly been used by a government that has now for centuries been based in Vienna. Österreichische Kanzleisprache is now used less and less, thanks to various administrative reforms that reduced the number of traditional civil servants (Beamter). As a result, Standard German is replacing it in government and administrative texts. === European Union === When Austria became a member of the European Union, the Austrian variety of the German language — limited to 23 agricultural terms — was "protected" in Protocol no. 10, regarding the use of Austrian-specific terms in the framework of the European Union, which forms part of the Austrian EU accession treaty. Austrian German is the only variety of a pluricentric language recognized under international law or EU primary law. All facts concerning “Protocol no. 10” are documented in Markhardt's Das österreichische Deutsch im Rahmen der EU, Peter Lang, 2005. === Grammar === ==== Verbs ==== In Austria, as in the German-speaking parts of Switzerland and in southern Germany, verbs that express a state tend to use sein as the auxiliary verb in the perfect, as well as verbs of movement. Verbs which fall into this category include sitzen (to sit), liegen (to lie) and, in parts of Carinthia, schlafen (to sleep). Therefore, the perfect of these verbs would be ich bin gesessen, ich bin gelegen and ich bin geschlafen respectively (note: ich bin geschlafen is a rarely used form, more commonly ich habe geschlafen is used). In Germany, the words stehen (to stand) and gestehen (to confess) are identical in the present perfect: habe gestanden. The Austrian variant avoids this potential ambiguity (bin gestanden from stehen, "to stand"; and habe gestanden from gestehen, "to confess", e.g. "der Verbrecher ist vor dem Richter gestanden und hat gestanden"). In addition, the preterite (simple past) is very rarely used in Austria, especially in the spoken language, with the exception of some modal verbs (i.e. ich sollte, ich wollte). === Vocabulary === There are many official terms that differ in Austrian German from their usage in most parts of Germany. Words primarily used in Austria are Jänner (January) rather than Januar, Feber (February) rather than Februar, heuer (this year) rather than dieses Jahr, Stiege (stairs) instead of Treppe, Rauchfang (chimney) instead of Schornstein, many administrative, legal and political terms – and a whole series of foods such as: Erdäpfel (potatoes) German Kartoffeln (but Dutch aardappel), Schlagobers (whipped cream) German Schlagsahne, Faschiertes (ground beef) German Hackfleisch (but Hungarian fasírt, Croatian and Slovenian informal faširano), Fisolen (green beans) German Gartenbohnen (but Czech fazole, Italian fagioli, Croatian (regional) fažol, Slovenian fižol, Hungarian folkish paszuly), Karfiol (cauliflower) German Blumenkohl (but Croatian, Hungarian and Slovak karfiol, Italian cavolfiore), Kohlsprossen (Brussels sprouts) German Rosenkohl, Marillen (apricots) German Aprikosen (but Slovak marhuľa, Polish morela, Slovenian marelice, Croatian marelica), Paradeiser ["Paradiesapfel"] (tomatoes) German Tomaten (but Hungarian paradicsom, Slovak paradajka, Slovenian paradižnik, Serbian paradajz), Palatschinken (pancakes) German Pfannkuchen (but Czech palačinky, Hungarian palacsinta, Croatian and Slovenian palačinke), Topfen (a semi-sweet cottage cheese) German Quark and Kren (horseradish) German Meerrettich (but Czech křen, Slovak chren, Croatian and Slovenian hren, etc.).There are, however, some false friends between the two regional varieties: Kasten (wardrobe) instead of Schrank, as opposed to Kiste (box) instead of Kasten. Kiste in Germany means both "box" and "chest". Sessel (chair) instead of Stuhl. Sessel means "easy chair" in Germany and Stuhl means "stool (faeces)" in both varieties. Vorzimmer (hall[way]) instead of Diele. Vorzimmer means "antechamber" in Germany Ofen (oven) instead of Kamin. Kamin is Schornstein (chimney) in Germany Polster (pillow) instead of Kissen. Topfen (quark) instead of Quark. == Dialects == === Classification === Dialects of the Austro-Bavarian group, which also comprises the dialects of German Bavaria Central Austro-Bavarian (along the main rivers Isar and Danube, spoken in the northern parts of the State of Salzburg, Upper Austria, Lower Austria, and northern Burgenland) Viennese German Southern Austro-Bavarian (in Tyrol, South Tyrol, Carinthia, Styria, and the southern parts of Salzburg and Burgenland) Vorarlbergerisch, spoken in Vorarlberg, is a High Alemannic dialect. === Regional accents === In addition to the standard variety, in everyday life most Austrians speak one of a number of Upper German dialects. While strong forms of the various dialects are not fully mutually intelligible to northern Germans, communication is much easier in Bavaria, especially rural areas, where the Bavarian dialect still predominates as the mother tongue. The Central Austro-Bavarian dialects are more intelligible to speakers of Standard German than the Southern Austro-Bavarian dialects of Tyrol. Viennese, the Austro-Bavarian dialect of Vienna, is seen for many in Germany as quintessentially Austrian. The people of Graz, the capital of Styria, speak yet another dialect which is not very Styrian and more easily understood by people from other parts of Austria than other Styrian dialects, for example from western Styria. Simple words in the various dialects are very similar, but pronunciation is distinct for each and, after listening to a few spoken words, it may be possible for an Austrian to realise which dialect is being spoken. However, in regard to the dialects of the deeper valleys of the Tirol, other Tyroleans are often unable to understand them. Speakers from the different states of Austria can easily be distinguished from each other by their particular accents (probably more so than Bavarians), those of Carinthia, Styria, Vienna, Upper Austria, and the Tyrol being very characteristic. Speakers from those regions, even those speaking Standard German, can usually be easily identified by their accent, even by an untrained listener. Several of the dialects have been influenced by contact with non-Germanic linguistic groups, such as the dialect of Carinthia, where in the past many speakers were bilingual with Slovene, and the dialect of Vienna, which has been influenced by immigration during the Austro-Hungarian period, particularly from what is today the Czech Republic. The German dialects of South Tyrol have been influenced by local Romance languages, particularly noticeable with the many loanwords from Italian and Ladin. The geographic borderlines between the different accents (isoglosses) coincide strongly with the borders of the states and also with the border with Bavaria, with Bavarians having a markedly different rhythm of speech in spite of the linguistic similarities. == See also == Bavarian language German language == References == == External links == Dictionary Austrian German - German Das Österreichische Volkswörterbuch == Sources == ### Answer: <German dialects>, <Languages of Austria>, <Languages with ISO 639-1 code>, <Upper German languages>

### Instruction: retrieve labels for this: In mathematics, the axiom of choice, or AC, is an axiom of set theory equivalent to the statement that the Cartesian product of a collection of non-empty sets is non-empty. Informally put, the axiom of choice says that given any collection of bins, each containing at least one object, it is possible to make a selection of exactly one object from each bin, even if the collection is infinite. Formally, it states that for every indexed family ( S i ) i ∈ I {\displaystyle (S_{i})_{i\in I}} of nonempty sets there exists an indexed family ( x i ) i ∈ I {\displaystyle (x_{i})_{i\in I}} of elements such that x i ∈ S i {\displaystyle x_{i}\in S_{i}} for every i ∈ I {\displaystyle i\in I} . The axiom of choice was formulated in 1904 by Ernst Zermelo in order to formalize his proof of the well-ordering theorem.In many cases, such a selection can be made without invoking the axiom of choice; this is in particular the case if the number of sets is finite, or if a selection rule is available: a distinguishing property that happens to hold for exactly one element in each set. An illustrative example is sets picked from the natural numbers. From such sets, one may always select the smallest number, e.g. in {{4,5,6}, {10,12}, {1,400,617,8000}} the smallest elements are {4, 10, 1}. In this case, "select the smallest number" is a choice function. Even if infinitely many sets were collected from the natural numbers, it will always be possible to choose the smallest element from each set to produce a set. That is, the choice function provides the set of chosen elements. However, no choice function is known for the collection of all non-empty subsets of the real numbers (if there are non-constructible reals). In that case, the axiom of choice must be invoked. Russell coined an analogy: for any (even infinite) collection of pairs of shoes, one can pick out the left shoe from each pair to obtain an appropriate selection; this makes it possible to directly define a choice function. For an infinite collection of pairs of socks (assumed to have no distinguishing features), there is no obvious way to make a function that selects one sock from each pair, without invoking the axiom of choice.Although originally controversial, the axiom of choice is now used without reservation by most mathematicians, and it is included in the standard form of axiomatic set theory, Zermelo–Fraenkel set theory with the axiom of choice (ZFC). One motivation for this use is that a number of generally accepted mathematical results, such as Tychonoff's theorem, require the axiom of choice for their proofs. Contemporary set theorists also study axioms that are not compatible with the axiom of choice, such as the axiom of determinacy. The axiom of choice is avoided in some varieties of constructive mathematics, although there are varieties of constructive mathematics in which the axiom of choice is embraced. == Statement == A choice function is a function f, defined on a collection X of nonempty sets, such that for every set A in X, f(A) is an element of A. With this concept, the axiom can be stated: Formally, this may be expressed as follows: ∀ X [ ∅ ∉ X ⟹ ∃ f : X → ⋃ X ∀ A ∈ X ( f ( A ) ∈ A ) ] . {\displaystyle \forall X\left[\emptyset \notin X\implies \exists f\colon X\rightarrow \bigcup X\quad \forall A\in X\,(f(A)\in A)\right]\,.} Thus, the negation of the axiom of choice states that there exists a collection of nonempty sets that has no choice function. Each choice function on a collection X of nonempty sets is an element of the Cartesian product of the sets in X. This is not the most general situation of a Cartesian product of a family of sets, where a given set can occur more than once as a factor; however, one can focus on elements of such a product that select the same element every time a given set appears as factor, and such elements correspond to an element of the Cartesian product of all distinct sets in the family. The axiom of choice asserts the existence of such elements; it is therefore equivalent to: Given any family of nonempty sets, their Cartesian product is a nonempty set. === Nomenclature ZF, AC, and ZFC === In this article and other discussions of the Axiom of Choice the following abbreviations are common: AC – the Axiom of Choice. ZF – Zermelo–Fraenkel set theory omitting the Axiom of Choice. ZFC – Zermelo–Fraenkel set theory, extended to include the Axiom of Choice. === Variants === There are many other equivalent statements of the axiom of choice. These are equivalent in the sense that, in the presence of other basic axioms of set theory, they imply the axiom of choice and are implied by it. One variation avoids the use of choice functions by, in effect, replacing each choice function with its range. Given any set X of pairwise disjoint non-empty sets, there exists at least one set C that contains exactly one element in common with each of the sets in X.This guarantees for any partition of a set X the existence of a subset C of X containing exactly one element from each part of the partition. Another equivalent axiom only considers collections X that are essentially powersets of other sets: For any set A, the power set of A (with the empty set removed) has a choice function.Authors who use this formulation often speak of the choice function on A, but be advised that this is a slightly different notion of choice function. Its domain is the powerset of A (with the empty set removed), and so makes sense for any set A, whereas with the definition used elsewhere in this article, the domain of a choice function on a collection of sets is that collection, and so only makes sense for sets of sets. With this alternate notion of choice function, the axiom of choice can be compactly stated as Every set has a choice function.which is equivalent to For any set A there is a function f such that for any non-empty subset B of A, f(B) lies in B.The negation of the axiom can thus be expressed as: There is a set A such that for all functions f (on the set of non-empty subsets of A), there is a B such that f(B) does not lie in B. === Restriction to finite sets === The statement of the axiom of choice does not specify whether the collection of nonempty sets is finite or infinite, and thus implies that every finite collection of nonempty sets has a choice function. However, that particular case is a theorem of the Zermelo–Fraenkel set theory without the axiom of choice (ZF); it is easily proved by mathematical induction. In the even simpler case of a collection of one set, a choice function just corresponds to an element, so this instance of the axiom of choice says that every nonempty set has an element; this holds trivially. The axiom of choice can be seen as asserting the generalization of this property, already evident for finite collections, to arbitrary collections. == Usage == Until the late 19th century, the axiom of choice was often used implicitly, although it had not yet been formally stated. For example, after having established that the set X contains only non-empty sets, a mathematician might have said "let F(s) be one of the members of s for all s in X." In general, it is impossible to prove that F exists without the axiom of choice, but this seems to have gone unnoticed until Zermelo. Not every situation requires the axiom of choice. For finite sets X, the axiom of choice follows from the other axioms of set theory. In that case it is equivalent to saying that if we have several (a finite number of) boxes, each containing at least one item, then we can choose exactly one item from each box. Clearly we can do this: We start at the first box, choose an item; go to the second box, choose an item; and so on. The number of boxes is finite, so eventually our choice procedure comes to an end. The result is an explicit choice function: a function that takes the first box to the first element we chose, the second box to the second element we chose, and so on. (A formal proof for all finite sets would use the principle of mathematical induction to prove "for every natural number k, every family of k nonempty sets has a choice function.") This method cannot, however, be used to show that every countable family of nonempty sets has a choice function, as is asserted by the axiom of countable choice. If the method is applied to an infinite sequence (Xi : i∈ω) of nonempty sets, a function is obtained at each finite stage, but there is no stage at which a choice function for the entire family is constructed, and no "limiting" choice function can be constructed, in general, in ZF without the axiom of choice. == Examples == The nature of the individual nonempty sets in the collection may make it possible to avoid the axiom of choice even for certain infinite collections. For example, suppose that each member of the collection X is a nonempty subset of the natural numbers. Every such subset has a smallest element, so to specify our choice function we can simply say that it maps each set to the least element of that set. This gives us a definite choice of an element from each set, and makes it unnecessary to apply the axiom of choice. The difficulty appears when there is no natural choice of elements from each set. If we cannot make explicit choices, how do we know that our set exists? For example, suppose that X is the set of all non-empty subsets of the real numbers. First we might try to proceed as if X were finite. If we try to choose an element from each set, then, because X is infinite, our choice procedure will never come to an end, and consequently, we shall never be able to produce a choice function for all of X. Next we might try specifying the least element from each set. But some subsets of the real numbers do not have least elements. For example, the open interval (0,1) does not have a least element: if x is in (0,1), then so is x/2, and x/2 is always strictly smaller than x. So this attempt also fails. Additionally, consider for instance the unit circle S, and the action on S by a group G consisting of all rational rotations. Namely, these are rotations by angles which are rational multiples of π. Here G is countable while S is uncountable. Hence S breaks up into uncountably many orbits under G. Using the axiom of choice, we could pick a single point from each orbit, obtaining an uncountable subset X of S with the property that all of its translates by G are disjoint from X. The set of those translates partitions the circle into a countable collection of disjoint sets, which are all pairwise congruent. Since X is not measurable for any rotation-invariant countably additive finite measure on S, finding an algorithm to select a point in each orbit requires the axiom of choice. See non-measurable set for more details. The reason that we are able to choose least elements from subsets of the natural numbers is the fact that the natural numbers are well-ordered: every nonempty subset of the natural numbers has a unique least element under the natural ordering. One might say, "Even though the usual ordering of the real numbers does not work, it may be possible to find a different ordering of the real numbers which is a well-ordering. Then our choice function can choose the least element of every set under our unusual ordering." The problem then becomes that of constructing a well-ordering, which turns out to require the axiom of choice for its existence; every set can be well-ordered if and only if the axiom of choice holds. == Criticism and acceptance == A proof requiring the axiom of choice may establish the existence of an object without explicitly defining the object in the language of set theory. For example, while the axiom of choice implies that there is a well-ordering of the real numbers, there are models of set theory with the axiom of choice in which no well-ordering of the reals is definable. Similarly, although a subset of the real numbers that is not Lebesgue measurable can be proved to exist using the axiom of choice, it is consistent that no such set is definable.The axiom of choice proves the existence of these intangibles (objects that are proved to exist, but which cannot be explicitly constructed), which may conflict with some philosophical principles. Because there is no canonical well-ordering of all sets, a construction that relies on a well-ordering may not produce a canonical result, even if a canonical result is desired (as is often the case in category theory). This has been used as an argument against the use of the axiom of choice. Another argument against the axiom of choice is that it implies the existence of objects that may seem counterintuitive. One example is the Banach–Tarski paradox which says that it is possible to decompose the 3-dimensional solid unit ball into finitely many pieces and, using only rotations and translations, reassemble the pieces into two solid balls each with the same volume as the original. The pieces in this decomposition, constructed using the axiom of choice, are non-measurable sets. Despite these seemingly paradoxical facts, most mathematicians accept the axiom of choice as a valid principle for proving new results in mathematics. The debate is interesting enough, however, that it is considered of note when a theorem in ZFC (ZF plus AC) is logically equivalent (with just the ZF axioms) to the axiom of choice, and mathematicians look for results that require the axiom of choice to be false, though this type of deduction is less common than the type which requires the axiom of choice to be true. It is possible to prove many theorems using neither the axiom of choice nor its negation; such statements will be true in any model of ZF, regardless of the truth or falsity of the axiom of choice in that particular model. The restriction to ZF renders any claim that relies on either the axiom of choice or its negation unprovable. For example, the Banach–Tarski paradox is neither provable nor disprovable from ZF alone: it is impossible to construct the required decomposition of the unit ball in ZF, but also impossible to prove there is no such decomposition. Similarly, all the statements listed below which require choice or some weaker version thereof for their proof are unprovable in ZF, but since each is provable in ZF plus the axiom of choice, there are models of ZF in which each statement is true. Statements such as the Banach–Tarski paradox can be rephrased as conditional statements, for example, "If AC holds, then the decomposition in the Banach–Tarski paradox exists." Such conditional statements are provable in ZF when the original statements are provable from ZF and the axiom of choice. == In constructive mathematics == As discussed above, in ZFC, the axiom of choice is able to provide "nonconstructive proofs" in which the existence of an object is proved although no explicit example is constructed. ZFC, however, is still formalized in classical logic. The axiom of choice has also been thoroughly studied in the context of constructive mathematics, where non-classical logic is employed. The status of the axiom of choice varies between different varieties of constructive mathematics. In Martin-Löf type theory and higher-order Heyting arithmetic, the appropriate statement of the axiom of choice is (depending on approach) included as an axiom or provable as a theorem. Errett Bishop argued that the axiom of choice was constructively acceptable, saying A choice function exists in constructive mathematics, because a choice is implied by the very meaning of existence. In constructive set theory, however, Diaconescu's theorem shows that the axiom of choice implies the law of excluded middle (unlike in Martin-Löf type theory, where it does not). Thus the axiom of choice is not generally available in constructive set theory. A cause for this difference is that the axiom of choice in type theory does not have the extensionality properties that the axiom of choice in constructive set theory does.Some results in constructive set theory use the axiom of countable choice or the axiom of dependent choice, which do not imply the law of the excluded middle in constructive set theory. Although the axiom of countable choice in particular is commonly used in constructive mathematics, its use has also been questioned. == Independence == In 1938, Kurt Gödel showed that the negation of the axiom of choice is not a theorem of ZF by constructing an inner model (the constructible universe) which satisfies ZFC and thus showing that ZFC is consistent if ZF itself is consistent. In 1963, Paul Cohen employed the technique of forcing, developed for this purpose, to show that: assuming ZF is consistent, the axiom of choice itself is not a theorem of ZF by constructing a much more complex model which satisfies ZF¬C (ZF with the negation of AC added as axiom) and thus showing that ZF¬C is consistent. Together these results establish that the axiom of choice is logically independent of ZF. The assumption that ZF is consistent is harmless because adding another axiom to an already inconsistent system cannot make the situation worse. Because of independence, the decision whether to use the axiom of choice (or its negation) in a proof cannot be made by appeal to other axioms of set theory. The decision must be made on other grounds. One argument given in favor of using the axiom of choice is that it is convenient to use it because it allows one to prove some simplifying propositions that otherwise could not be proved. Many theorems which are provable using choice are of an elegant general character: every ideal in a ring is contained in a maximal ideal, every vector space has a basis, and every product of compact spaces is compact. Without the axiom of choice, these theorems may not hold for mathematical objects of large cardinality. The proof of the independence result also shows that a wide class of mathematical statements, including all statements that can be phrased in the language of Peano arithmetic, are provable in ZF if and only if they are provable in ZFC. Statements in this class include the statement that P = NP, the Riemann hypothesis, and many other unsolved mathematical problems. When one attempts to solve problems in this class, it makes no difference whether ZF or ZFC is employed if the only question is the existence of a proof. It is possible, however, that there is a shorter proof of a theorem from ZFC than from ZF. The axiom of choice is not the only significant statement which is independent of ZF. For example, the generalized continuum hypothesis (GCH) is not only independent of ZF, but also independent of ZFC. However, ZF plus GCH implies AC, making GCH a strictly stronger claim than AC, even though they are both independent of ZF. == Stronger axioms == The axiom of constructibility and the generalized continuum hypothesis each imply the axiom of choice and so are strictly stronger than it. In class theories such as Von Neumann–Bernays–Gödel set theory and Morse–Kelley set theory, there is an axiom called the axiom of global choice that is stronger than the axiom of choice for sets because it also applies to proper classes. The axiom of global choice follows from the axiom of limitation of size. == Equivalents == There are important statements that, assuming the axioms of ZF but neither AC nor ¬AC, are equivalent to the axiom of choice. The most important among them are Zorn's lemma and the well-ordering theorem. In fact, Zermelo initially introduced the axiom of choice in order to formalize his proof of the well-ordering theorem. Set theory Well-ordering theorem: Every set can be well-ordered. Consequently, every cardinal has an initial ordinal. Tarski's theorem about choice: For every infinite set A, there is a bijective map between the sets A and A×A. Trichotomy: If two sets are given, then either they have the same cardinality, or one has a smaller cardinality than the other. The Cartesian product of any family of nonempty sets is nonempty. König's theorem: Colloquially, the sum of a sequence of cardinals is strictly less than the product of a sequence of larger cardinals. (The reason for the term "colloquially" is that the sum or product of a "sequence" of cardinals cannot be defined without some aspect of the axiom of choice.) Every surjective function has a right inverse. Order theory Zorn's lemma: Every non-empty partially ordered set in which every chain (i.e., totally ordered subset) has an upper bound contains at least one maximal element. Hausdorff maximal principle: In any partially ordered set, every totally ordered subset is contained in a maximal totally ordered subset. The restricted principle "Every partially ordered set has a maximal totally ordered subset" is also equivalent to AC over ZF. Tukey's lemma: Every non-empty collection of finite character has a maximal element with respect to inclusion. Antichain principle: Every partially ordered set has a maximal antichain. Abstract algebra Every vector space has a basis. Krull's theorem: Every unital ring other than the trivial ring contains a maximal ideal. For every non-empty set S there is a binary operation defined on S that gives it a group structure. (A cancellative binary operation is enough, see group structure and the axiom of choice.) Every set is a projective object in the category Set of sets. Functional analysis The closed unit ball of the dual of a normed vector space over the reals has an extreme point. Point-set topology Tychonoff's theorem: Every product of compact topological spaces is compact. In the product topology, the closure of a product of subsets is equal to the product of the closures. Mathematical logic If S is a set of sentences of first-order logic and B is a consistent subset of S, then B is included in a set that is maximal among consistent subsets of S. The special case where S is the set of all first-order sentences in a given signature is weaker, equivalent to the Boolean prime ideal theorem; see the section "Weaker forms" below. Graph theory Every connected graph has a spanning tree. === Category theory === There are several results in category theory which invoke the axiom of choice for their proof. These results might be weaker than, equivalent to, or stronger than the axiom of choice, depending on the strength of the technical foundations. For example, if one defines categories in terms of sets, that is, as sets of objects and morphisms (usually called a small category), or even locally small categories, whose hom-objects are sets, then there is no category of all sets, and so it is difficult for a category-theoretic formulation to apply to all sets. On the other hand, other foundational descriptions of category theory are considerably stronger, and an identical category-theoretic statement of choice may be stronger than the standard formulation, à la class theory, mentioned above. Examples of category-theoretic statements which require choice include: Every small category has a skeleton. If two small categories are weakly equivalent, then they are equivalent. Every continuous functor on a small-complete category which satisfies the appropriate solution set condition has a left-adjoint (the Freyd adjoint functor theorem). == Weaker forms == There are several weaker statements that are not equivalent to the axiom of choice, but are closely related. One example is the axiom of dependent choice (DC). A still weaker example is the axiom of countable choice (ACω or CC), which states that a choice function exists for any countable set of nonempty sets. These axioms are sufficient for many proofs in elementary mathematical analysis, and are consistent with some principles, such as the Lebesgue measurability of all sets of reals, that are disprovable from the full axiom of choice. Other choice axioms weaker than axiom of choice include the Boolean prime ideal theorem and the axiom of uniformization. The former is equivalent in ZF to the existence of an ultrafilter containing each given filter, proved by Tarski in 1930. === Results requiring AC (or weaker forms) but weaker than it === One of the most interesting aspects of the axiom of choice is the large number of places in mathematics that it shows up. Here are some statements that require the axiom of choice in the sense that they are not provable from ZF but are provable from ZFC (ZF plus AC). Equivalently, these statements are true in all models of ZFC but false in some models of ZF. Set theory Any union of countably many countable sets is itself countable (because it is necessary to choose a particular ordering for each of the countably many sets). If the set A is infinite, then there exists an injection from the natural numbers N to A (see Dedekind infinite). Eight definitions of a finite set are equivalent. Every infinite game G S {\displaystyle G_{S}} in which S {\displaystyle S} is a Borel subset of Baire space is determined. Measure theory The Vitali theorem on the existence of non-measurable sets which states that there is a subset of the real numbers that is not Lebesgue measurable. The Hausdorff paradox. The Banach–Tarski paradox. The Lebesgue measure of a countable disjoint union of measurable sets is equal to the sum of the measures of the individual sets. Algebra Every field has an algebraic closure. Every field extension has a transcendence basis. Stone's representation theorem for Boolean algebras needs the Boolean prime ideal theorem. The Nielsen–Schreier theorem, that every subgroup of a free group is free. The additive groups of R and C are isomorphic. Functional analysis The Hahn–Banach theorem in functional analysis, allowing the extension of linear functionals The theorem that every Hilbert space has an orthonormal basis. The Banach–Alaoglu theorem about compactness of sets of functionals. The Baire category theorem about complete metric spaces, and its consequences, such as the open mapping theorem and the closed graph theorem. On every infinite-dimensional topological vector space there is a discontinuous linear map. General topology A uniform space is compact if and only if it is complete and totally bounded. Every Tychonoff space has a Stone–Čech compactification. Mathematical logic Gödel's completeness theorem for first-order logic: every consistent set of first-order sentences has a completion. That is, every consistent set of first-order sentences can be extended to a maximal consistent set. == Stronger forms of the negation of AC == Now, consider stronger forms of the negation of AC. For example, if we abbreviate by BP the claim that every set of real numbers has the property of Baire, then BP is stronger than ¬AC, which asserts the nonexistence of any choice function on perhaps only a single set of nonempty sets. Note that strengthened negations may be compatible with weakened forms of AC. For example, ZF + DC + BP is consistent, if ZF is. It is also consistent with ZF + DC that every set of reals is Lebesgue measurable; however, this consistency result, due to Robert M. Solovay, cannot be proved in ZFC itself, but requires a mild large cardinal assumption (the existence of an inaccessible cardinal). The much stronger axiom of determinacy, or AD, implies that every set of reals is Lebesgue measurable, has the property of Baire, and has the perfect set property (all three of these results are refuted by AC itself). ZF + DC + AD is consistent provided that a sufficiently strong large cardinal axiom is consistent (the existence of infinitely many Woodin cardinals). Quine's system of axiomatic set theory, "New Foundations" (NF), takes its name from the title (“New Foundations for Mathematical Logic”) of the 1937 article which introduced it. In the NF axiomatic system, the axiom of choice can be disproved. == Statements consistent with the negation of AC == There are models of Zermelo-Fraenkel set theory in which the axiom of choice is false. We shall abbreviate "Zermelo-Fraenkel set theory plus the negation of the axiom of choice" by ZF¬C. For certain models of ZF¬C, it is possible to prove the negation of some standard facts. Note that any model of ZF¬C is also a model of ZF, so for each of the following statements, there exists a model of ZF in which that statement is true. There exists a model of ZF¬C in which there is a function f from the real numbers to the real numbers such that f is not continuous at a, but f is sequentially continuous at a, i.e., for any sequence {xn} converging to a, limn f(xn)=f(a). There exists a model of ZF¬C which has an infinite set of real numbers without a countably infinite subset. There exists a model of ZF¬C in which real numbers are a countable union of countable sets. There exists a model of ZF¬C in which there is a field with no algebraic closure. In all models of ZF¬C there is a vector space with no basis. There exists a model of ZF¬C in which there is a vector space with two bases of different cardinalities. There exists a model of ZF¬C in which there is a free complete boolean algebra on countably many generators.For proofs, see Jech (2008). There exists a model of ZF¬C in which every set in Rn is measurable. Thus it is possible to exclude counterintuitive results like the Banach–Tarski paradox which are provable in ZFC. Furthermore, this is possible whilst assuming the Axiom of dependent choice, which is weaker than AC but sufficient to develop most of real analysis. In all models of ZF¬C, the generalized continuum hypothesis does not hold. == Axiom of choice in type theory == In type theory, a different kind of statement is known as the axiom of choice. This form begins with two types, σ and τ, and a relation R between objects of type σ and objects of type τ. The axiom of choice states that if for each x of type σ there exists a y of type τ such that R(x,y), then there is a function f from objects of type σ to objects of type τ such that R(x,f(x)) holds for all x of type σ: ( ∀ x σ ) ( ∃ y τ ) R ( x , y ) → ( ∃ f σ → τ ) ( ∀ x σ ) R ( x , f ( x ) ) . {\displaystyle (\forall x^{\sigma })(\exists y^{\tau })R(x,y)\to (\exists f^{\sigma \to \tau })(\forall x^{\sigma })R(x,f(x)).} Unlike in set theory, the axiom of choice in type theory is typically stated as an axiom scheme, in which R varies over all formulas or over all formulas of a particular logical form. == Quotes == The Axiom of Choice is obviously true, the well-ordering principle obviously false, and who can tell about Zorn's lemma? This is a joke: although the three are all mathematically equivalent, many mathematicians find the axiom of choice to be intuitive, the well-ordering principle to be counterintuitive, and Zorn's lemma to be too complex for any intuition. The Axiom of Choice is necessary to select a set from an infinite number of pairs of socks, but not an infinite number of pairs of shoes. The observation here is that one can define a function to select from an infinite number of pairs of shoes by stating for example, to choose a left shoe. Without the axiom of choice, one cannot assert that such a function exists for pairs of socks, because left and right socks are (presumably) indistinguishable. Tarski tried to publish his theorem [the equivalence between AC and "every infinite set A has the same cardinality as A × A", see above] in Comptes Rendus, but Fréchet and Lebesgue refused to present it. Fréchet wrote that an implication between two well known [true] propositions is not a new result, and Lebesgue wrote that an implication between two false propositions is of no interest. Polish-American mathematician Jan Mycielski relates this anecdote in a 2006 article in the Notices of the AMS. The axiom gets its name not because mathematicians prefer it to other axioms. This quote comes from the famous April Fools' Day article in the computer recreations column of the Scientific American, April 1989. == Notes == == References == Halmos, Paul R. (1960).

### Instruction: retrieve labels for this: Attila (; fl. circa 406–453), frequently called Attila the Hun, was the ruler of the Huns from 434 until his death in March 453. He was also the leader of a tribal empire consisting of Huns, Ostrogoths, and Alans among others, on the territory of Central and Eastern Europe. During his reign, he was one of the most feared enemies of the Western and Eastern Roman Empires. He crossed the Danube twice and plundered the Balkans, but was unable to take Constantinople. His unsuccessful campaign in Persia was followed in 441 by an invasion of the Eastern Roman (Byzantine) Empire, the success of which emboldened Attila to invade the West. He also attempted to conquer Roman Gaul (modern France), crossing the Rhine in 451 and marching as far as Aurelianum (Orléans) before being defeated at the Battle of the Catalaunian Plains. He subsequently invaded Italy, devastating the northern provinces, but was unable to take Rome. He planned for further campaigns against the Romans, but died in 453. After Attila's death, his close adviser, Ardaric of the Gepids, led a Germanic revolt against Hunnic rule, after which the Hunnic Empire quickly collapsed. == Appearance and character == There is no surviving first-hand account of Attila's appearance, but there is a possible second-hand source provided by Jordanes, who cites a description given by Priscus. He was a man born into the world to shake the nations, the scourge of all lands, who in some way terrified all mankind by the dreadful rumors noised abroad concerning him. He was haughty in his walk, rolling his eyes hither and thither, so that the power of his proud spirit appeared in the movement of his body. He was indeed a lover of war, yet restrained in action, mighty in counsel, gracious to suppliants and lenient to those who were once received into his protection. Short of stature, with a broad chest and a large head; his eyes were small, his beard thin and sprinkled with grey; and he had a flat nose and tanned skin, showing evidence of his origin.:182–183 Some scholars have suggested that this description is typically East Asian, because it has all the combined features that fit the physical type of people from Eastern Asia, and Attila's ancestors may have come from there.:202 Other historians also believed that the same descriptions were also evident on some Scythian people. == Etymology == The origin of the name "Attila" is unclear, and there is no consensus among scholars.:177Otto J. Maenchen-Helfen considered an East Germanic origin; Attila is formed from the Gothic or Gepidic noun atta, "father", by means of the diminutive suffix -ila,:386 meaning "little father". The Gothic etymology can be tracked up to Jacob Grimm and Wilhelm Grimm in the early 19th century. Maenchen-Helfen noted that Hunnic names were "not the true names of the Hun princes and lords. What we have are Hunnic names in Germanic dress, modified to fit the Gothic tongue, or popular Gothic etymologies, or both".:389 Peter Heather, who strongly considered Germanic etymology of the name Attila and some of noble Huns,:29–30, 177 stated that the possibility Attila was of Germanic ancestry cannot be ruled out. The names of Attila's brother Bleda, and most powerful minister Onegesius, also have hypothetical Germanic etymology. The only credible Germanic etymologies are for Attila's blood relative Laudaricus,:388 and the Hun-Goth Ragnaris.:383, 389Hyun Jin Kim argued that the "Germanization of Hunnic names may have been a conscious policy among the Hunnic elite in the West in order to ease the transition to their rule of formerly independent German tribal unions".:93 In the Western part of Hunnic Empire, where mostly lived subjected Gothic tribes, Huns probably spoke both Hunnic and Gothic language, and as such bore Germanized or Germanic name, like Laudaricus.:30 Maenchen-Helfen also expressed concern over orthography of the writer, possible morphological change, that some names writers heard from the Goths, the tendency of Roman and Byzantine writers to alter foreign names, and manuscript corruption.:381–382However, Kim noted that those names considered by Heather to be Gothic, especially in this case of Attila and Bleda, have more natural and probable Turkic etymology.:30 Heather also ignored the fact that all Hunnic rulers before Attila, as well his father Mundzuk, paternal uncles Octar, Ruga and Oebarsius, wife Kreka, father-in-law Eskam, and sons Ellac, Dengizich and Ernak, have names of Turkic origin.:30Omeljan Pritsak considered Ἀττίλα (Attíla) a composite title-name which derived from Turkic *es (great, old), and *t il (sea, ocean), and the suffix /a/.:444 The stressed back syllabic til assimilated the front member es, so it became *as.:444 It is a nominative, in form of attíl- (< *etsíl < *es tíl) with the meaning "the oceanic, universal ruler".:444 Peter Golden, citing Pritsak, like László Rásonyi connected Attila's name with Menander note in which used term Attilan as the name of the Volga River (Turkic Atil/Itil; "great river").:90 J.J. Mikkola connected it with Turkic āt (name, fame). H. Althof considered it was related to Turkish atli (horseman, cavalier), or Turkish at (horse) and dil (tongue).Tom Shippey in his work Goths and Huns: The Rediscovery of Northern Cultures in the Nineteenth Century (1982), argued that the Gothic etymology is a product of 19th century Germanic romantic philological revisionism.:177 M. Snædal casts doubt on the Germanic origin of the name Attila in a recently published article. "The Gothic origin of the name Attila is questionable," Snædal writes. "It is at least as likely to be of Hunnic origin". The article points out that the word atta is a migratory term for "father/forefather" common in multiple languages, including many Turkic languages (see Ata). The article also indicates that Attila's name could have originated from Turkic-Mongolian at, adyy/agta (gelding, warhorse) and Turkish atli (horseman, cavalier), meaning "possessor of geldings, provider of warhorses", a suitable name for a warlord. He concludes: Of course we do not know how the name sounded in the language of the Huns. Sometime, somewhere, somehow a proto-form like *agtala- changed to *attila. We cannot tell if the assimilation of "gt" to "tt", and/or if loss of a final consonant took place in Hunnic or if these changes were part of the adaptation process into Latin, Gothic and Greek... Truly, our knowledge of the Hunnic language is almost zero. One can only guess a solution to this riddle of Attila's name. The name has many variants in several languages: Atli and Atle in Old Norse; Etzel in Middle High German (Nibelungenlied); Ætla in Old English; Attila, Atilla, and Etele in Hungarian (Attila is the most popular); Attila, Atilla, Atilay, or Atila in Turkish; and Adil and Edil in Kazakh or Adil ("same/similar") or Edil ("to use") in Mongolian. == Historiography and source == The historiography of Attila is faced with a major challenge, in that the only complete sources are written in Greek and Latin by the enemies of the Huns. Attila's contemporaries left many testimonials of his life, but only fragments of these remain.:25 Priscus was a Byzantine diplomat and historian who wrote in Greek, and he was both a witness to and an actor in the story of Attila, as a member of the embassy of Theodosius II at the Hunnic court in 449. He was obviously biased by his political position, but his writing is a major source for information on the life of Attila, and he is the only person known to have recorded a physical description of him. He wrote a history of the late Roman Empire in eight books covering the period from 430 to 476.Today we have only fragments of Priscus' work, but it was cited extensively by 6th-century historians Procopius and Jordanes,:413 especially in Jordanes' The Origin and Deeds of the Goths. It contains numerous references to Priscus's history, and it is also an important source of information about the Hunnic empire and its neighbors. He describes the legacy of Attila and the Hunnic people for a century after Attila's death. Marcellinus Comes, a chancellor of Justinian during the same era, also describes the relations between the Huns and the Eastern Roman Empire.:30Numerous ecclesiastical writings contain useful but scattered information, sometimes difficult to authenticate or distorted by years of hand-copying between the 6th and 17th centuries. The Hungarian writers of the 12th century wished to portray the Huns in a positive light as their glorious ancestors, and so repressed certain historical elements and added their own legends.:32The literature and knowledge of the Huns themselves was transmitted orally, by means of epics and chanted poems that were handed down from generation to generation.:354 Indirectly, fragments of this oral history have reached us via the literature of the Scandinavians and Germans, neighbors of the Huns who wrote between the 9th and 13th centuries. Attila is a major character in many Medieval epics, such as the Nibelungenlied, as well as various Eddas and sagas.:32:354Archaeological investigation has uncovered some details about the lifestyle, art, and warfare of the Huns. There are a few traces of battles and sieges, but today the tomb of Attila and the location of his capital have not yet been found.:33–37 == Early life and background == The Huns were a group of Eurasian nomads, appearing from east of the Volga, who migrated further into Western Europe c. 370 and built up an enormous empire there. Their main military techniques were mounted archery and javelin throwing. They were in the process of developing settlements before their arrival in Western Europe, yet the Huns were a society of pastoral warriors:259 whose primary form of nourishment was meat and milk, products of their herds. The origin and language of the Huns has been the subject of debate for centuries. According to some theories, their leaders at least may have spoken a Turkic language, perhaps closest to the modern Chuvash language.:444 One scholar suggests a relationship to Yeniseian. According to the Encyclopedia of European Peoples, "the Huns, especially those who migrated to the west, may have been a combination of central Asian Turkic, Mongolic, and Ugric stocks".Attila's father Mundzuk was the brother of kings Octar and Ruga, who reigned jointly over the Hunnic empire in the early fifth century. This form of diarchy was recurrent with the Huns, but historians are unsure whether it was institutionalized, merely customary, or an occasional occurrence.:80 His family was from a noble lineage, but it is uncertain whether they constituted a royal dynasty. Attila's birthdate is debated, journalist Éric Deschodt and writer Herman Schreiber have proposed a date of 395. However, historian Iaroslav Lebedynsky and archaeologist Katalin Escher prefer an estimate between the 390s and the first decade of the fifth century.:40 Several historians have proposed 406 as the date.:92:202Attila grew up in a rapidly changing world. His people were nomads who had only recently arrived in Europe. They crossed the Volga river during the 370s and annexed the territory of the Alans, then attacked the Gothic kingdom between the Carpathian mountains and the Danube. They were a very mobile people, whose mounted archers had acquired a reputation of invincibility, and the Germanic tribes seemed unable to withstand them.:133–151 Vast populations fleeing the Huns moved from Germania into the Roman Empire in the west and south, and along the banks of the Rhine and Danube. In 376, the Goths crossed the Danube, initially submitting to the Romans but soon rebelling against Emperor Valens, whom they killed in the Battle of Adrianople in 378.:100 Large numbers of Vandals, Alans, Suebi, and Burgundians crossed the Rhine and invaded Roman Gaul on December 31, 406 to escape the Huns.:233 The Roman Empire had been split in half since 395 and was ruled by two distinct governments, one based in Ravenna in the West, and the other in Constantinople in the East. The Roman Emperors, both East and West, were generally from the Theodosian family in Attila's lifetime (despite several power struggles).:13The Huns dominated a vast territory with nebulous borders determined by the will of a constellation of ethnically varied peoples. Some were assimilated to Hunnic nationality, whereas many retained their own identities and rulers but acknowledged the suzerainty of the king of the Huns.:11 The Huns were also the indirect source of many of the Romans' problems, driving various Germanic tribes into Roman territory, yet relations between the two empires were cordial: the Romans used the Huns as mercenaries against the Germans and even in their civil wars. Thus, the usurper Joannes was able to recruit thousands of Huns for his army against Valentinian III in 424. It was Aëtius, later Patrician of the West, who managed this operation. They exchanged ambassadors and hostages, the alliance lasting from 401 to 450 and permitting the Romans numerous military victories.:111 The Huns considered the Romans to be paying them tribute, whereas the Romans preferred to view this as payment for services rendered. The Huns had become a great power by the time that Attila came of age during the reign of his uncle Ruga, to the point that Nestorius, the Patriarch of Constantinople, deplored the situation with these words: "They have become both masters and slaves of the Romans".:128 == Campaigns against the Eastern Roman Empire == The death of Rugila (also known as Rua or Ruga) in 434 left the sons of his brother Mundzuk, Attila and Bleda, in control of the united Hun tribes. At the time of the two brothers' accession, the Hun tribes were bargaining with Eastern Roman Emperor Theodosius II's envoys for the return of several renegades who had taken refuge within the Eastern Roman Empire, possibly Hunnic nobles who disagreed with the brothers' assumption of leadership. The following year, Attila and Bleda met with the imperial legation at Margus (Požarevac), all seated on horseback in the Hunnic manner, and negotiated an advantageous treaty. The Romans agreed to return the fugitives, to double their previous tribute of 350 Roman pounds (c. 115 kg) of gold, to open their markets to Hunnish traders, and to pay a ransom of eight solidi for each Roman taken prisoner by the Huns. The Huns, satisfied with the treaty, decamped from the Roman Empire and returned to their home in the Great Hungarian Plain, perhaps to consolidate and strengthen their empire. Theodosius used this opportunity to strengthen the walls of Constantinople, building the city's first sea wall, and to build up his border defenses along the Danube. The Huns remained out of Roman sight for the next few years while they invaded the Sassanid Empire. They were defeated in Armenia by the Sassanids, abandoned their invasion, and turned their attentions back to Europe. In 440, they reappeared in force on the borders of the Roman Empire, attacking the merchants at the market on the north bank of the Danube that had been established by the treaty. Crossing the Danube, they laid waste to the cities of Illyricum and forts on the river, including (according to Priscus) Viminacium, a city of Moesia. Their advance began at Margus, where they demanded that the Romans turn over a bishop who had retained property that Attila regarded as his. While the Romans discussed the bishop's fate, he slipped away secretly to the Huns and betrayed the city to them. While the Huns attacked city-states along the Danube, the Vandals (led by Geiseric) captured the Western Roman province of Africa and its capital of Carthage. Carthage was the richest province of the Western Empire and a main source of food for Rome. The Sassanid Shah Yazdegerd II invaded Armenia in 441. The Romans stripped the Balkan area of forces, sending them to Sicily in order to mount an expedition against the Vandals in Africa. This left Attila and Bleda a clear path through Illyricum into the Balkans, which they invaded in 441. The Hunnish army sacked Margus and Viminacium, and then took Singidunum (Belgrade) and Sirmium. During 442, Theodosius recalled his troops from Sicily and ordered a large issue of new coins to finance operations against the Huns. He believed that he could defeat the Huns and refused the Hunnish kings' demands. Attila responded with a campaign in 443. The Huns were equipped with new military weapons as they advanced along the Danube, such as battering rams and rolling siege towers, and they overran the military centers of Ratiara and successfully besieged Naissus (Niš). Advancing along the Nišava River, the Huns next took Serdica (Sofia), Philippopolis (Plovdiv), and Arcadiopolis (Lüleburgaz). They encountered and destroyed a Roman army outside Constantinople but were stopped by the double walls of the Eastern capital. They defeated a second army near Callipolis (Gelibolu). Theodosius, stripped of his armed forces, admitted defeat, sending the Magister militum per Orientem Anatolius to negotiate peace terms. The terms were harsher than the previous treaty: the Emperor agreed to hand over 6,000 Roman pounds (c. 2000 kg) of gold as punishment for having disobeyed the terms of the treaty during the invasion; the yearly tribute was tripled, rising to 2,100 Roman pounds (c. 700 kg) in gold; and the ransom for each Roman prisoner rose to 12 solidi. Their demands were met for a time, and the Hun kings withdrew into the interior of their empire. Bleda died following the Huns' withdrawal from Byzantium (probably around 445). Attila then took the throne for himself, becoming the sole ruler of the Huns. == Solitary kingship == In 447, Attila again rode south into the Eastern Roman Empire through Moesia. The Roman army, under Gothic magister militum Arnegisclus, met him in the Battle of the Utus and was defeated, though not without inflicting heavy losses. The Huns were left unopposed and rampaged through the Balkans as far as Thermopylae. Constantinople itself was saved by the Isaurian troops of magister militum per Orientem Zeno and protected by the intervention of prefect Constantinus, who organized the reconstruction of the walls that had been previously damaged by earthquakes and, in some places, to construct a new line of fortification in front of the old. An account of this invasion survives: The barbarian nation of the Huns, which was in Thrace, became so great that more than a hundred cities were captured and Constantinople almost came into danger and most men fled from it. ... And there were so many murders and blood-lettings that the dead could not be numbered. Ay, for they took captive the churches and monasteries and slew the monks and maidens in great numbers. == In the west == In 450, Attila proclaimed his intent to attack the Visigoth kingdom of Toulouse by making an alliance with Emperor Valentinian III. He had previously been on good terms with the Western Roman Empire and its influential general Flavius Aëtius. Aëtius had spent a brief exile among the Huns in 433, and the troops that Attila provided against the Goths and Bagaudae had helped earn him the largely honorary title of magister militum in the west. The gifts and diplomatic efforts of Geiseric, who opposed and feared the Visigoths, may also have influenced Attila's plans. However, Valentinian's sister was Honoria, who had sent the Hunnish king a plea for help—and her engagement ring—in order to escape her forced betrothal to a Roman senator in the spring of 450. Honoria may not have intended a proposal of marriage, but Attila chose to interpret her message as such. He accepted, asking for half of the western Empire as dowry. When Valentinian discovered the plan, only the influence of his mother Galla Placidia convinced him to exile Honoria, rather than killing her. He also wrote to Attila, strenuously denying the legitimacy of the supposed marriage proposal. Attila sent an emissary to Ravenna to proclaim that Honoria was innocent, that the proposal had been legitimate, and that he would come to claim what was rightfully his. Attila interfered in a succession struggle after the death of a Frankish ruler. Attila supported the elder son, while Aëtius supported the younger. (The location and identity of these kings is not known and subject to conjecture.) Attila gathered his vassals—Gepids, Ostrogoths, Rugians, Scirians, Heruls, Thuringians, Alans, Burgundians, among others–and began his march west. In 451, he arrived in Belgica with an army exaggerated by Jordanes to half a million strong. On April 7, he captured Metz. Other cities attacked can be determined by the hagiographic vitae written to commemorate their bishops: Nicasius was slaughtered before the altar of his church in Rheims; Servatus is alleged to have saved Tongeren with his prayers, as Saint Genevieve is said to have saved Paris. Lupus, bishop of Troyes, is also credited with saving his city by meeting Attila in person.Aëtius moved to oppose Attila, gathering troops from among the Franks, the Burgundians, and the Celts. A mission by Avitus and Attila's continued westward advance convinced the Visigoth king Theodoric I (Theodorid) to ally with the Romans. The combined armies reached Orléans ahead of Attila, thus checking and turning back the Hunnish advance. Aëtius gave chase and caught the Huns at a place usually assumed to be near Catalaunum (modern Châlons-en-Champagne). Attila decided to fight the Romans on plains where he could use his cavalry.The two armies clashed in the Battle of the Catalaunian Plains, the outcome of which is commonly considered to be a strategic victory for the Visigothic-Roman alliance. Theodoric was killed in the fighting, and Aëtius failed to press his advantage, according to Edward Gibbon and Edward Creasy, because he feared the consequences of an overwhelming Visigothic triumph as much as he did a defeat. From Aëtius' point of view, the best outcome was what occurred: Theodoric died, Attila was in retreat and disarray, and the Romans had the benefit of appearing victorious. == Invasion of Italy and death == Attila returned in 452 to renew his marriage claim with Honoria, invading and ravaging Italy along the way. Communities became established in what would later become Venice as a result of these attacks when the residents fled to small islands in the Venetian Lagoon. His army sacked numerous cities and razed Aquileia so completely that it was afterwards hard to recognize its original site.:159 Aëtius lacked the strength to offer battle, but managed to harass and slow Attila's advance with only a shadow force. Attila finally halted at the River Po. By this point, disease and starvation may have taken hold in Attila's camp, thus helping to stop his invasion.Emperor Valentinian III sent three envoys, the high civilian officers Gennadius Avienus and Trigetius, as well as the Bishop of Rome Leo I, who met Attila at Mincio in the vicinity of Mantua and obtained from him the promise that he would withdraw from Italy and negotiate peace with the Emperor. Prosper of Aquitaine gives a short description of the historic meeting, but gives all the credit to Leo for the successful negotiation. Priscus reports that superstitious fear of the fate of Alaric gave him pause—as Alaric died shortly after sacking Rome in 410. Italy had suffered from a terrible famine in 451 and her crops were faring little better in 452. Attila's devastating invasion of the plains of northern Italy this year did not improve the harvest.:161 To advance on Rome would have required supplies which were not available in Italy, and taking the city would not have improved Attila's supply situation. Therefore, it was more profitable for Attila to conclude peace and retreat to his homeland.:160–161Furthermore, an East Roman force had crossed the Danube under the command of another officer also named Aetius—who had participated in the Council of Chalcedon the previous year—and proceeded to defeat the Huns who had been left behind by Attila to safeguard their home territories. Attila, hence, faced heavy human and natural pressures to retire "from Italy without ever setting foot south of the Po".:163 As Hydatius writes in his Chronica Minora: The Huns, who had been plundering Italy and who had also stormed a number of cities, were victims of divine punishment, being visited with heaven-sent disasters: famine and some kind of disease. In addition, they were slaughtered by auxiliaries sent by the Emperor Marcian and led by Aetius, and at the same time, they were crushed in their [home] settlements ... Thus crushed, they made peace with the Romans and all returned to their homes. === Death === Marcian was the successor of Theodosius, and he had ceased paying tribute to the Huns in late 450 while Attila was occupied in the west. Multiple invasions by the Huns and others had left the Balkans with little to plunder. After Attila left Italy and returned to his palace across the Danube, he planned to strike at Constantinople again and reclaim the tribute which Marcian had stopped. However, he died in the early months of 453. The conventional account from Priscus says that Attila was at a feast celebrating his latest marriage, this time to the beautiful young Ildico (the name suggests Gothic or Ostrogoth origins).:164 In the midst of the revels, however, he suffered a severe nosebleed and choked to death in a stupor. An alternative theory is that he succumbed to internal bleeding after heavy drinking, possibly a condition called esophageal varices, where dilated veins in the lower part of the esophagus rupture leading to death by hemorrhage.Another account of his death was first recorded 80 years after the events by Roman chronicler Marcellinus Comes. It reports that "Attila, King of the Huns and ravager of the provinces of Europe, was pierced by the hand and blade of his wife". Most scholars reject these accounts as no more than hearsay, preferring instead the account given by Attila's contemporary Priscus. Priscus' version, however, has recently come under renewed scrutiny by Michael A. Babcock. Based on detailed philological analysis, Babcock concludes that the account of natural death given by Priscus was an ecclesiastical "cover story", and that Emperor Marcian (who ruled the Eastern Roman Empire from 450 to 457) was the political force behind Attila's death. Jordanes recounts: On the following day, when a great part of the morning was spent, the royal attendants suspected some ill and, after a great uproar, broke in the doors. There they found the death of Attila accomplished by an effusion of blood, without any wound, and the girl with downcast face weeping beneath her veil. Then, as is the custom of that race, they plucked out the hair of their heads and made their faces hideous with deep wounds, that the renowned warrior might be mourned, not by effeminate wailings and tears, but by the blood of men. Moreover a wondrous thing took place in connection with Attila's death. For in a dream some god stood at the side of Marcian, Emperor of the East, while he was disquieted about his fierce foe, and showed him the bow of Attila broken in that same night, as if to intimate that the race of Huns owed much to that weapon. This account the historian Priscus says he accepts upon truthful evidence. For so terrible was Attila thought to be to great empires that the gods announced his death to rulers as a special boon. His body was placed in the midst of a plain and lay in state in a silken tent as a sight for men's admiration. The best horsemen of the entire tribe of the Huns rode around in circles, after the manner of circus games, in the place to which he had been brought and told of his deeds in a funeral dirge in the following manner: "The chief of the Huns, King Attila, born of his sire Mundiuch, lord of bravest tribes, sole possessor of the Scythian and German realms—powers unknown before—captured cities and terrified both empires of the Roman world and, appeased by their prayers, took annual tribute to save the rest from plunder. And when he had accomplished all this by the favor of fortune, he fell, not by wound of the foe, nor by treachery of friends, but in the midst of his nation at peace, happy in his joy and without sense of pain. Who can rate this as death, when none believes it calls for vengeance?" When they had mourned him with such lamentations, a strava, as they call it, was celebrated over his tomb with great revelling. They gave way in turn to the extremes of feeling and displayed funereal grief alternating with joy. Then in the secrecy of night they buried his body in the earth. They bound his coffins, the first with gold, the second with silver and the third with the strength of iron, showing by such means that these three things suited the mightiest of kings; iron because he subdued the nations, gold and silver because he received the honors of both empires. They also added the arms of foemen won in the fight, trappings of rare worth, sparkling with various gems, and ornaments of all sorts whereby princely state is maintained. And that so great riches might be kept from human curiosity, they slew those appointed to the work—a dreadful pay for their labor; and thus sudden death was the lot of those who buried him as well as of him who was buried. Attila's sons Ellac, Dengizich and Ernak, "in their rash eagerness to rule they all alike destroyed his empire".:259 They "were clamoring that the nations should be divided among them equally and that warlike kings with their peoples should be apportioned to them by lot like a family estate".:259 Against the treatment as "slaves of the basest condition" a Germanic alliance led by the Gepid ruler Ardaric (who was noted for great loyalty to Attila:199) revolted and fought with the Huns in Pannonia in the Battle of Nedao 454 AD.:260–262 Attila's eldest son Ellac was killed in that battle.:262 Attila's sons "regarding the Goths as deserters from their rule, came against them as though they were seeking fugitive slaves", attacked Ostrogothic co-ruler Valamir (who also fought alongside Ardaric and Attila at the Catalaunian Plains:199), but were repelled, and some group of Huns moved to Scythia (probably those of Ernak).:268–269 His brother Dengizich attempted a renewed invasion across the Danube in 468 AD, but was defeated at the Battle of Bassianae by the Ostrogoths.:272–273 Dengizich was killed by Roman-Gothic general Anagast the following year, after which the Hunnic dominion ended.:168Attila's many children and relatives are known by name and some even by deeds, but soon valid genealogical sources all but dried up, and there seems to be no verifiable way to trace Attila's descendants. This has not stopped many genealogists from attempting to reconstruct a valid line of descent for various medieval rulers. One of the most credible claims has been that of the Nominalia of the Bulgarian khans for mythological Avitohol and Irnik from the Dulo clan of the Bulgars.:103:59, 142 == Later folklore and iconography == Attila himself is said to have claimed the titles "Descendant of the Great Nimrod", and "King of the Huns, the Goths, the Danes, and the Medes"—the last two peoples being mentioned to show the extent of his control over subject nations even on the peripheries of his domain.Jordanes embellished the report of Priscus, reporting that Attila had possessed the "Holy War Sword of the Scythians", which was given to him by Mars and made him a "prince of the entire world".By the end of the 12th century the royal court of Hungary proclaimed their descent from Attila. Lampert of Hersfeld's contemporary chronicles report that shortly before the year 1071, the Sword of Attila had been presented to Otto of Nordheim by the exiled queen of Hungary, Anastasia of Kiev. This sword, a cavalry sabre now in the Kunsthistorisches Museum in Vienna, appears to be the work of Hungarian goldsmiths of the ninth or tenth century.An anonymous chronicler of the medieval period represented the meeting of Pope Leo and Atilla as attended also by Saint Peter and Saint Paul, "a miraculous tale calculated to meet the taste of the time" This apotheosis was later portrayed artistically by the Renaissance artist Raphael and sculptor Algardi, whom eighteenth-century historian Edward Gibbon praised for establishing "one of the noblest legends of ecclesiastical tradition".According to a version of this narrative related in the Chronicon Pictum, a mediaeval Hungarian chronicle, the Pope promised Attila that if he left Rome in peace, one of his successors would receive a holy crown (which has been understood as referring to the Holy Crown of Hungary). Some histories and chronicles describe him as a great and noble king, and he plays major roles in three Norse sagas: Atlakviða, Volsunga saga, and Atlamál. The Polish Chronicle represents Attila's name as Aquila.Frutolf of Michelsberg and Otto of Freising pointed out that some songs as "vulgar fables" made Theoderic the Great, Attila and Ermanaric contemporaries, when any reader of Jordanes knew that this was not the case. This refers to the so-called historical poems about Dietrich von Bern (Theoderic), in which Etzel (Attila) is Dietrich's refuge in exile from his wicked uncle Ermenrich (Ermanaric). Etzel is most prominent in the poems Dietrichs Flucht and Die Rabenschlacht. Etzel also appears as Kriemhild's second noble husband in the Nibelungenlied, in which Kriemhild causes the destruction of both the Hunnish kingdom and that of her Burgundian relatives. In 1812, Ludwig van Beethoven conceived the idea of writing an opera about Attila and approached August von Kotzebue to write the libretto. It was, however, never written.In World War I, Allied propaganda referred to Germans as the "Huns", based on a 1900 speech by Emperor Wilhelm II praising Attila the Hun's military prowess, according to Jawaharlal Nehru's Glimpses of World History. Der Spiegel commented on November 6, 1948, that the Sword of Attila was hanging menacingly over Austria.American writer Cecelia Holland wrote The Death of Attila (1973), a historical novel in which Attila appears as a powerful background figure whose life and death deeply impact the protagonists, a young Hunnic warrior and a Germanic one. In modern Hungary and in Turkey, "Attila" and its Turkish variation "Atilla" are commonly used as a male first name. In Hungary, several public places are named after Attila; for instance, in Budapest there are 10 Attila Streets, one of which is an important street behind the Buda Castle. When the Turkish Armed Forces invaded Cyprus in 1974, the operations were named after Attila ("The Attila Plan").The 1954 Universal International film Sign of the Pagan starred Jack Palance as Attila. == Depictions of Attila == == Notes == Other sourcesFrazee, Charles A.

### Instruction: retrieve labels for this: The Aegean Sea (; Greek: Αιγαίο Πέλαγος [eˈʝeo ˈpelaɣos] ( listen); Turkish: Ege Denizi [eɟe denizi]) is an elongated embayment of the Mediterranean Sea located between the Greek and Anatolian peninsulas, i.e., between the mainlands of Greece and Turkey. In the north, the Aegean is connected to the Marmara Sea and Black Sea by the Dardanelles and Bosphorus. The Aegean Islands are within the sea and some bound it on its southern periphery, including Crete and Rhodes. The sea was traditionally known as the Archipelago (in Greek, Αρχιπέλαγος, meaning "chief sea"), but in English the meaning of Archipelago has changed to refer to the Aegean Islands and, generally, to any island group. == Etymology == In ancient times, there were various explanations for the name Aegean. It was said to have been named after the Greek town of Aegae; after Aegea, a queen of the Amazons who died in the sea; Aigaion, the "sea goat", another name of Briareus, one of the archaic Hecatonchires; or, especially among the Athenians, Aegeus, the father of Theseus, who drowned himself in the sea when he thought his son had died. A possible etymology is a derivation from the Greek word αἶγες – aiges = "waves" (Hesychius of Alexandria; metaphorical use of αἴξ (aix) "goat"), hence "wavy sea", cf. also αἰγιαλός (aigialos = aiges (waves) + hals (sea)), hence meaning "sea-shore". The Venetians, who ruled many Greek islands in the High and Late Middle Ages, popularized the name Archipelago (Greek for "main sea" or "chief sea"), a name that held on in many European countries until the early modern period. In some South Slavic languages the Aegean is often called White Sea (Belo more/Бело море in Serbo-Croatian and Macedonian; Бяло море Byalo more in Bulgarian). == Geography == The Aegean Sea covers about 214,000 square kilometres (83,000 sq mi) in area, and measures about 610 kilometres (380 mi) longitudinally and 300 kilometres (190 mi) latitudinally. The sea's maximum depth is 3,543 metres (11,624 ft), east of Crete. The Aegean Islands are found within its waters, with the following islands delimiting the sea on the south (generally from west to east): Kythera, Antikythera, Crete, Kasos, Karpathos and Rhodes. The Aegean Islands, which almost all belong to Greece, can be divided into seven groups: Northeastern Aegean Islands (Thracian Sea) East Aegean Islands (Euboea) Northern Sporades Cyclades Saronic Islands (or Argo-Saronic Islands) Dodecanese (or Southern Sporades), with the exclusion of Kastellorizo CreteThe word archipelago was originally applied specifically to the Aegean Sea and its islands. Many of the Aegean Islands, or chains of islands, are actually extensions of the mountains on the mainland. One chain extends across the sea to Chios, another extends across Euboea to Samos, and a third extends across the Peloponnese and Crete to Rhodes, dividing the Aegean from the Mediterranean. The bays and gulfs of the Aegean beginning at the South and moving clockwise include on Crete, the Mirabello, Almyros, Souda and Chania bays or gulfs, on the mainland the Myrtoan Sea to the west with the Argolic Gulf, the Saronic Gulf northwestward, the Petalies Gulf which connects with the South Euboic Sea, the Pagasetic Gulf which connects with the North Euboic Sea, the Thermian Gulf northwestward, the Chalkidiki Peninsula including the Cassandra and the Singitic Gulfs, northward the Strymonian Gulf and the Gulf of Kavala and the rest are in Turkey; Saros Gulf, Edremit Gulf, Dikili Gulf, Gulf of Çandarlı, Gulf of İzmir, Gulf of Kuşadası, Gulf of Gökova, Güllük Gulf. === Extent === The International Hydrographic Organization defines the limits of the Aegean Sea as follows: On the South. A line running from Cape Aspro (28°16'E) in Asia Minor, to Cum Burnù (Capo della Sabbia) the Northeast extreme of the Island of Rhodes, through the island to Cape Prasonisi, the Southwest point thereof, on to Vrontos Point (35°33'N) in Skarpanto [Karpathos], through this island to Castello Point, the South extreme thereof, across to Cape Plaka (East extremity of Crete), through Crete to Agria Grabusa, the Northwest extreme thereof, thence to Cape Apolitares in Antikithera Island, through the island to Psira Rock (off the Northwest point) and across to Cape Trakhili in Kithera Island, through Kithera to the Northwest point (Cape Karavugia) and thence to Cape Santa Maria (36°28′N 22°57′E) in the Morea. In the Dardanelles. A line joining Kum Kale (26°11'E) and Cape Helles. === Hydrography === Aegean surface water circulates in a counter-clockwise gyre, with hypersaline Mediterranean water moving northward along the west coast of Turkey, before being displaced by less dense Black Sea outflow. The dense Mediterranean water sinks below the Black Sea inflow to a depth of 23–30 metres (75–98 ft), then flows through the Dardanelles Strait and into the Sea of Marmara at velocities of 5–15 cm/s. The Black Sea outflow moves westward along the northern Aegean Sea, then flows southwards along the east coast of Greece.The physical oceanography of the Aegean Sea is controlled mainly by the regional climate, the fresh water discharge from major rivers draining southeastern Europe, and the seasonal variations in the Black Sea surface water outflow through the Dardanelles Strait. Analysis of the Aegean during 1991 and 1992 revealed 3 distinct water masses: Aegean Sea Surface Water – 40–50 metres (130–160 ft) thick veneer, with summer temperatures of 21–26 °C and winter temperatures ranging from 10 °C (50 °F) in the north to 16 °C (61 °F) in the south. Aegean Sea Intermediate Water – Aegean Sea Intermediate Water extends from 40–50 m to 200–300 metres (660–980 ft) with temperatures ranging from 11–18 °C. Aegean Sea Bottom Water – occurring at depths below 500–1000 m with a very uniform temperature (13–14 °C) and salinity (3.91–3.92%). == History == === Ancient history === The current coastline dates back to about 4000 BC. Before that time, at the peak of the last ice age (c. 16,000 BC) sea levels everywhere were 130 metres lower, and there were large well-watered coastal plains instead of much of the northern Aegean. When they were first occupied, the present-day islands including Milos with its important obsidian production were probably still connected to the mainland. The present coastal arrangement appeared c. 7000 BC, with post-ice age sea levels continuing to rise for another 3,000 years after that.The subsequent Bronze Age civilizations of Greece and the Aegean Sea have given rise to the general term Aegean civilization. In ancient times, the sea was the birthplace of two ancient civilizations – the Minoans of Crete and the Myceneans of the Peloponnese.Later arose the city-states of Athens and Sparta among many others that constituted the Athenian Empire and Hellenic Civilization. Plato described the Greeks living round the Aegean "like frogs around a pond". The Aegean Sea was later invaded by the Persians and the Romans, and inhabited by the Eastern Romans (Byzantine-Greeks), the Bulgarians, the Venetians, the Genoese, the Seljuq Turks, and the Ottomans. The Aegean was the site of the original democracies, and its seaways were the means of contact among several diverse civilizations of the Eastern Mediterranean. == Economy and politics == Many of the islands in the Aegean have safe harbours and bays. In ancient times, navigation through the sea was easier than travelling across the rough terrain of the Greek mainland (and to some extent the coastal areas of Anatolia). Many of the islands are volcanic, and marble and iron are mined on other islands. The larger islands have some fertile valleys and plains. Of the main islands in the Aegean Sea, two belong to Turkey – Bozcaada (Tenedos Τένεδος) and Gökçeada (Imbros Ίμβρος); the rest belong to Greece. Between the two countries, there are political disputes over several aspects of political control over the Aegean space, including the size of territorial waters, air control and the delimitation of economic rights to the continental shelf. == See also == Aegean languages List of Greek place names Thracian Sea == References == == External links == "Cultural Portal of the Aegean Archipelago".

### Instruction: retrieve labels for this: Amsterdam (, UK also ; Dutch: [ɑmstərˈdɑm] ( listen)) is the capital and most populous municipality of the Netherlands. Its status as the capital is mandated by the Constitution of the Netherlands, although it is not the seat of the government, which is The Hague. Amsterdam has a population of 851,373 within the city proper, 1,351,587 in the urban area, and 2,410,960 in the Amsterdam metropolitan area. The city is located in the province of North Holland in the west of the country but is not its capital, which is Haarlem. The metropolitan area comprises much of the northern part of the Randstad, one of the larger conurbations in Europe, with a population of approximately 8 million.Amsterdam's name derives from Amstelredamme, indicative of the city's origin around a dam in the river Amstel. Originating as a small fishing village in the late 12th century, Amsterdam became one of the most important ports in the world during the Dutch Golden Age (17th century), a result of its innovative developments in trade. During that time, the city was the leading centre for finance and diamonds. In the 19th and 20th centuries the city expanded, and many new neighbourhoods and suburbs were planned and built. The 17th-century canals of Amsterdam and the 19–20th century Defence Line of Amsterdam are on the UNESCO World Heritage List. Since the annexation of the municipality of Sloten in 1921 by the municipality of Amsterdam, the oldest historic part of the city lies in Sloten (9th century). As the commercial capital of the Netherlands and one of the top financial centres in Europe, Amsterdam is considered an alpha world city by the Globalization and World Cities (GaWC) study group. The city is also the cultural capital of the Netherlands. Many large Dutch institutions have their headquarters there, and seven of the world's 500 largest companies, including Philips, AkzoNobel, TomTom and ING, are based in the city. Also, many leading technology companies have their European headquarters in Amsterdam, such as Uber, Netflix and Tesla. In 2012, Amsterdam was ranked the second best city to live in by the Economist Intelligence Unit (EIU) and 12th globally on quality of living for environment and infrastructure by Mercer. The city was ranked 3rd in innovation by Australian innovation agency 2thinknow in their Innovation Cities Index 2009. The Port of Amsterdam to this day remains the second in the country, and the fifth largest seaport in Europe. Famous Amsterdam residents include the diarist Anne Frank, artists Rembrandt van Rijn and Vincent van Gogh, and philosopher Baruch Spinoza. The Amsterdam Stock Exchange, the oldest stock exchange in the world, is located in the city centre. Amsterdam's main attractions, including its historic canals, the Rijksmuseum, the Van Gogh Museum, the Stedelijk Museum, Hermitage Amsterdam, the Anne Frank House, the Amsterdam Museum, its red-light district and its many cannabis coffee shops draw more than 5 million international visitors annually. The city is also well known for its nightlife and festival activity; several of its nightclubs (Melkweg, Paradiso) are among the world's most famous. It is also one of the world's most multicultural cities, with at least 177 nationalities represented. == Etymology == After the floods of 1170 and 1173, locals near the river Amstel built a bridge over the river and a dam across it, giving its name to the village: "Aemstelredamme". The earliest recorded use of that name is in a document dated October 27, 1275, which exempted inhabitants of the village from paying bridge tolls to Count Floris V. This allowed the inhabitants of the village of Aemstelredamme to travel freely through the County of Holland, paying no tolls at bridges, locks and dams. The certificate describes the inhabitants as homines manentes apud Amestelledamme (people residing near Amestelledamme). By 1327, the name had developed into Aemsterdam. == History == === Founding and Middle Ages === Amsterdam is much younger than Dutch cities such as Nijmegen, Rotterdam, and Utrecht. In October 2008, historical geographer Chris de Bont suggested that the land around Amsterdam was being reclaimed as early as the late 10th century. This does not necessarily mean that there was already a settlement then, since reclamation of land may not have been for farming—it may have been for peat, for use as fuel.Amsterdam was granted city rights in either 1300 or 1306. From the 14th century on, Amsterdam flourished, largely from trade with the Hanseatic League. In 1345, an alleged Eucharistic miracle in the Kalverstraat rendered the city an important place of pilgrimage until the adoption of the Protestant faith. The Miracle devotion went underground but was kept alive. In the 19th century, especially after the jubilee of 1845, the devotion was revitalized and became an important national point of reference for Dutch Catholics. The Stille Omgang—a silent walk or procession in civil attire—is the expression of the pilgrimage within the Protestant Netherlands since the late 19th century. In the heyday of the Silent Walk, up to 90,000 pilgrims came to Amsterdam. In the 21st century this has reduced to about 5000. === Conflict with Spain === In the 16th century, the Dutch rebelled against Philip II of Spain and his successors. The main reasons for the uprising were the imposition of new taxes, the tenth penny, and the religious persecution of Protestants by the newly introduced Inquisition. The revolt escalated into the Eighty Years' War, which ultimately led to Dutch independence. Strongly pushed by Dutch Revolt leader William the Silent, the Dutch Republic became known for its relative religious tolerance. Jews from the Iberian Peninsula, Huguenots from France, prosperous merchants and printers from Flanders, and economic and religious refugees from the Spanish-controlled parts of the Low Countries found safety in Amsterdam. The influx of Flemish printers and the city's intellectual tolerance made Amsterdam a centre for the European free press. === Centre of the Dutch Golden Age === The 17th century is considered Amsterdam's Golden Age, during which it became the wealthiest city in the western world. Ships sailed from Amsterdam to the Baltic Sea, North America, and Africa, as well as present-day Indonesia, India, Sri Lanka, and Brazil, forming the basis of a worldwide trading network. Amsterdam's merchants had the largest share in both the Dutch East India Company and the Dutch West India Company. These companies acquired overseas possessions that later became Dutch colonies. Amsterdam was Europe's most important point for the shipment of goods and was the leading Financial centre of the western world. In 1602, the Amsterdam office of the international trading Dutch East India Company became the world's first stock exchange by trading in its own shares. The Bank of Amsterdam started operations in 1609, acting as a full service bank for Dutch merchant bankers and as a reserve bank. === Decline and modernisation === Amsterdam's prosperity declined during the 18th and early 19th centuries. The wars of the Dutch Republic with England and France took their toll on Amsterdam. During the Napoleonic Wars, Amsterdam's significance reached its lowest point, with Holland being absorbed into the French Empire. However, the later establishment of the United Kingdom of the Netherlands in 1815 marked a turning point. The end of the 19th century is sometimes called Amsterdam's second Golden Age. New museums, a railway station, and the Concertgebouw were built; in this same time, the Industrial Revolution reached the city. The Amsterdam–Rhine Canal was dug to give Amsterdam a direct connection to the Rhine, and the North Sea Canal was dug to give the port a shorter connection to the North Sea. Both projects dramatically improved commerce with the rest of Europe and the world. In 1906, Joseph Conrad gave a brief description of Amsterdam as seen from the seaside, in The Mirror of the Sea. === 20th century–present === Shortly before the First World War, the city started to expand again, and new suburbs were built. Even though the Netherlands remained neutral in this war, Amsterdam suffered a food shortage, and heating fuel became scarce. The shortages sparked riots in which several people were killed. These riots are known as the Aardappeloproer (Potato rebellion). People started looting stores and warehouses in order to get supplies, mainly food.On 1 January 1921, after a flood in 1916, the depleted municipalities of Durgerdam, Holysloot, Zunderdorp and Schellingwoude, all lying north of Amsterdam, were, at their own request, annexed to the city. Between the wars, the city continued to expand, most notably to the west of the Jordaan district in the Frederik Hendrikbuurt and surrounding neighbourhoods. Nazi Germany invaded the Netherlands on 10 May 1940 and took control of the country. Some Amsterdam citizens sheltered Jews, thereby exposing themselves and their families to a high risk of being imprisoned or sent to concentration camps. More than 100,000 Dutch Jews were deported to Nazi concentration camps, of whom some 60,000 lived in Amsterdam. In response, the Dutch Communist Party organised the February strike attended by 300,000 people to protest against the raids. Perhaps the most famous deportee was the young Jewish girl Anne Frank, who died in the Bergen-Belsen concentration camp. At the end of the Second World War, communication with the rest of the country broke down, and food and fuel became scarce. Many citizens travelled to the countryside to forage. Dogs, cats, raw sugar beets, and Tulip bulbs—cooked to a pulp—were consumed to stay alive. Most of the trees in Amsterdam were cut down for fuel, and all the wood was taken from the apartments of deported Jews. Many new suburbs, such as Osdorp, Slotervaart, Slotermeer and Geuzenveld, were built in the years after the Second World War. These suburbs contained many public parks and wide open spaces, and the new buildings provided improved housing conditions with larger and brighter rooms, gardens, and balconies. Because of the war and other events of the 20th century, almost the entire city centre had fallen into disrepair. As society was changing, politicians and other influential figures made plans to redesign large parts of it. There was an increasing demand for office buildings, and also for new roads, as the automobile became available to most people. A metro started operating in 1977 between the new suburb of Bijlmer and the centre of Amsterdam. Further plans were to build a new highway above the metro to connect Amsterdam Centraal and city centre with other parts of the city. The required large-scale demolitions began in Amsterdam's former Jewish neighbourhood. Smaller streets, such as the Jodenbreestraat, were widened and almost all of their houses were demolished. At the peak of the demolition, the Nieuwmarktrellen (Nieuwmarkt Riots) broke out; the rioters expressed their fury about the demolition caused by the restructuring of the city. As a result, the demolition was stopped, and the highway was never built; only the metro was completed. Only a few streets remained widened. The new city hall was built on the almost completely demolished Waterlooplein. Meanwhile, large private organisations, such as Stadsherstel Amsterdam, were founded with the aim of restoring the entire city centre. Although the success of this struggle is visible today, efforts for further restoration are still ongoing. The entire city centre has reattained its former splendour and, as a whole, is now a protected area. Many of its buildings have become monuments, and in July 2010 the Grachtengordel (the three concentric canals: Herengracht, Keizersgracht, and Prinsengracht) was added to the UNESCO World Heritage List. In the early years of the 21st century, the Amsterdam city centre has attracted large numbers of tourists: between 2012 and 2015, the annual number of visitors rose from 10 million to 17 million. Real estate prices have surged, and local shops are making way for tourist-oriented ones, making the centre unaffordable for the city's inhabitants. These developments have evoked comparisons with Venice, a city thought to be overwhelmed by the tourist influx.Construction of a metro line connecting the part of the city north of the river (or lake) IJ to the centre was started in 2003. The project is controversial because its cost had exceeded its budget by a factor three by 2008, because of fears of damage to buildings in the centre, and because construction had to be halted and restarted multiple times.Since 2014, renewed focus has been given to urban regeneration and renewal, especially in areas directly bordering the city centre, such as Frederik Hendrikbuurt. This urban renewal and expansion of the traditional centre of the city—with the construction on artificial islands of the new eastern IJburg neighbourhood—is part of the Structural Vision Amsterdam 2040 initiative. == Geography == Amsterdam is located in the Western Netherlands, in the province of North Holland, although it is not its capital which is Haarlem. The river Amstel ends in the city centre and connects to a large number of canals that eventually terminate in the IJ. Amsterdam is about 2 metres (6.6 feet) below sea level. The surrounding land is flat as it is formed of large polders. A man-made forest, Amsterdamse Bos, is in the southwest. Amsterdam is connected to the North Sea through the long North Sea Canal. Amsterdam is intensely urbanised, as is the Amsterdam metropolitan area surrounding the city. Comprising 219.4 square kilometres (84.7 square miles) of land, the city proper has 4,457 inhabitants per km2 and 2,275 houses per km2. Parks and nature reserves make up 12% of Amsterdam's land area. === Water === Amsterdam has more than 100 kilometres (60 miles) of canals, most of which are navigable by boat. The city's three main canals are the Prinsengracht, Herengracht, and Keizersgracht. In the Middle Ages, Amsterdam was surrounded by a moat, called the Singel, which now forms the innermost ring in the city, and makes the city centre a horseshoe shape. The city is also served by a seaport. It has been compared with Venice, due to its division into about 90 islands, which are linked by more than 1,200 bridges. === Climate === Amsterdam has an oceanic climate (Köppen climate classification Cfb) strongly influenced by its proximity to the North Sea to the west, with prevailing westerly winds. Both winters and summers are considered mild, although winters can get quite cold, while summers are quite warm occasionally. Amsterdam, as well as most of the North Holland province, lies in USDA Hardiness zone 8b. Frosts mainly occur during spells of easterly or northeasterly winds from the inner European continent. Even then, because Amsterdam is surrounded on three sides by large bodies of water, as well as having a significant heat-island effect, nights rarely fall below −5 °C (23 °F), while it could easily be −12 °C (10 °F) in Hilversum, 25 kilometres (16 miles) southeast. Summers are moderately warm with a number of hot days every month. The average daily high in August is 22.1 °C (71.8 °F), and 30 °C (86 °F) or higher is only measured on average on 2.5 days, placing Amsterdam in AHS Heat Zone 2. The record extremes range from −19.7 °C (−3.5 °F) to 35.7 °C (96.3 °F). Days with more than 1 millimetre (0.04 in) of precipitation are common, on average 133 days per year. Amsterdam's average annual precipitation is 838 millimetres (33 in), more than what is measured at Amsterdam Schiphol Airport. A large part of this precipitation falls as light rain or brief showers. Cloudy and damp days are common during the cooler months of October through March. == Demographics == === Historical population === Compared to other important towns in the County of Holland, such as Dordrecht, Leiden, Haarlem, Delft and Alkmaar, Amsterdam is a relatively young city. In stark contrast to the relative decline of those other towns, Amsterdam's population grew in the 15th and 16th centuries, mainly due to the rise of the profitable Baltic maritime trade after the Burgundian victory in the Dutch–Hanseatic War. Still, the population of Amsterdam and other towns in Holland was only modest compared to the towns and cities of Flanders and Brabant, which comprised the most urbanised area of the Low Countries. This changed when, during the Dutch Revolt, many people from the Southern Netherlands fled to the North, especially after Antwerp fell to Spanish forces in 1585. In thirty years, Amsterdam's population more than doubled from 41,362 inhabitants in 1590 to 106,500 inhabitants in 1620. During the 1660s, Amsterdam's population reached 200,000. The city's growth levelled off and the population stabilised around 240,000 for most of the 18th century. At the turn of the 18th century, Amsterdam was the fourth largest city in Europe, behind Constantinople (about 700,000), London (550,000) and Paris (530,000). This was all the more remarkable as Amsterdam was neither the capital city nor the seat of government of the Dutch Republic, which itself was a much smaller state than England, France or the Ottoman Empire. In contrast to those other metropolises, Amsterdam was also surrounded by large towns such as Leiden (about 67,000), Rotterdam (45,000), Haarlem (38,000), and Utrecht (30,000).The city's population declined in the late 18th and early 19th centuries, dipping under 200,000 in 1820. By the second half of the 19th century, industrialisation spurred renewed growth. Amsterdam's population hit an all-time high of 872,000 in 1959, before declining in the following decades due to government-sponsored suburbanisation to so-called groeikernen (growth centres) such as Purmerend and Almere. Between 1970 and 1980, Amsterdam experienced its sharpest population decline ever, and by 1985 the city had only 675,570 residents. This was soon followed by reurbanisation and gentrification, however, leading to renewed population growth in the 2010s. The municipal department for Research, Information and Statistics expects a new record population to be set in 2020. === Immigration === In the 16th and 17th century non-Dutch immigrants to Amsterdam were mostly Huguenots, Flemings, Sephardi Jews and Westphalians. Huguenots came after the Edict of Fontainebleau in 1685, while the Flemish Protestants came during the Eighty Years' War. The Westphalians came to Amsterdam mostly for economic reasons – their influx continued through the 18th and 19th centuries. Before the Second World War, 10% of the city population was Jewish. Just twenty per cent of them survived the Shoah.The first mass immigration in the 20th century were by people from Indonesia, who came to Amsterdam after the independence of the Dutch East Indies in the 1940s and 1950s. In the 1960s guest workers from Turkey, Morocco, Italy and Spain emigrated to Amsterdam. After the independence of Suriname in 1975, a large wave of Surinamese settled in Amsterdam, mostly in the Bijlmer area. Other immigrants, including refugees asylum seekers and illegal immigrants, came from Europe, America, Asia, and Africa. In the 1970s and 1980s, many 'old' Amsterdammers moved to 'new' cities like Almere and Purmerend, prompted by the third planological bill of the Dutch government. This bill promoted suburbanisation and arranged for new developments in so-called "groeikernen", literally cores of growth. Young professionals and artists moved into neighbourhoods de Pijp and the Jordaan abandoned by these Amsterdammers. The non-Western immigrants settled mostly in the social housing projects in Amsterdam-West and the Bijlmer. Today, people of non-Western origin make up approximately one-third of the population of Amsterdam, and more than 50% of the city' s children. Ethnic Dutch (as defined by the Dutch census) now make up a minority of the total population, although by far the largest one. Only one in three inhabitants under 15 is an autochtoon. Segregation along ethnic lines is clearly visible, with people of non-Western origin, considered a separate group by Statistics Netherlands, concentrating in specific neighbourhoods especially in Nieuw-West, Zeeburg, Bijlmer and in certain areas of Amsterdam-Noord.In 2000, Christians formed the largest religious group in the city (17% of the population). The next largest religion was Islam (14%), most of whose followers were Sunni. === Religion === In 1578, the previously Roman Catholic city of Amsterdam joined the revolt against Spanish rule, late in comparison to other major northern Dutch cities. Following the Dutch takeover, all churches were converted to Protestant worship. Calvinism became the dominant religion, and although Catholicism was not forbidden and priests allowed to serve, the Catholic hierarchy was prohibited. This led to the establishment of schuilkerken, covert churches, behind seemingly ordinary canal side house fronts. One example is the current debate centre de Rode Hoed. A large influx of foreigners of many religions came to 17th-century Amsterdam, in particular Sefardic Jews from Spain and Portugal, Huguenots from France, and Protestants from the Southern Netherlands. This led to the establishment of many non-Dutch-speaking religious churches. In 1603, the first notification was made of Jewish religious service. In 1639, the first synagogue was consecrated. The Jews came to call the town Jerusalem of the West, a reference to their sense of belonging there. As they became established in the city, other Christian denominations used converted Catholic chapels to conduct their own services. The oldest English-language church congregation in the world outside the United Kingdom is found at the Begijnhof. Regular services there are still offered in English under the auspices of the Church of Scotland. The Huguenots accounted for nearly 20% of Amsterdam's inhabitants in 1700. Being Calvinists, they soon integrated into the Dutch Reformed Church, though often retaining their own congregations. Some, commonly referred by the moniker 'Walloon', are recognisable today as they offer occasional services in French. In the second half of the 17th century, Amsterdam experienced an influx of Ashkenazim, Jews from Central and Eastern Europe, which continued into the 19th century. Jews often fled the pogroms in those areas. The first Ashkenazi who arrived in Amsterdam were refugees from the Chmielnicki Uprising in Poland and the Thirty Years' War. They not only founded their own synagogues, but had a strong influence on the 'Amsterdam dialect' adding a large Yiddish local vocabulary. Despite an absence of an official Jewish ghetto, most Jews preferred to live in the eastern part of the old medieval heart of the city. The main street of this Jewish neighbourhood was the Jodenbreestraat. The neighbourhood comprised the Waterlooplein and the Nieuwmarkt. Buildings in this neighbourhood fell into disrepair after the Second World War, and a large section of the neighbourhood was demolished during the construction of the subway. This led to riots, and as a result the original plans for large-scale reconstruction were abandoned and the neighbourhood was rebuilt with smaller-scale residence buildings on the basis of its original layout. Catholic churches in Amsterdam have been constructed since the restoration of the episcopal hierarchy in 1853. One of the principal architects behind the city's Catholic churches, Cuypers, was also responsible for the Amsterdam Central station and the Rijksmuseum, which led to a refusal of Protestant King William III to open 'that monastery'. In 1924, the Roman Catholic Church of the Netherlands hosted the International Eucharistic Congress in Amsterdam, and numerous Catholic prelates visited the city, where festivities were held in churches and stadiums. Catholic processions on the public streets, however, were still forbidden under law at the time. Only in the 20th century was Amsterdam's relation to Catholicism normalised, but despite its far larger population size, the Catholic clergy chose to place its episcopal see of the city in the nearby provincial town of Haarlem.In recent times, religious demographics in Amsterdam have been changed by immigration from former colonies. Hinduism has been introduced from the Hindu diaspora from Suriname and several distinct branches of Islam have been brought from various parts of the world. Islam is now the largest non-Christian religion in Amsterdam. The large community of Ghanaian and Nigerian immigrants have established African churches, often in parking garages in the Bijlmer area, where many have settled. In addition, a broad array of other religious movements have established congregations, including Hinduism, and Buddhism. Jews make up about 2% of the city's total population. === Diversity and immigration === Amsterdam experienced an influx of religions and cultures after the Second World War. With 180 different nationalities, Amsterdam is home to one of the widest varieties of nationalities of any city in the world. The proportion of the population of immigrant origin in the city proper is about 50% and 88% of the population are Dutch citizens.Amsterdam has been one of the municipalities in the Netherlands which provided immigrants with extensive and free Dutch-language courses, which have benefited many immigrants. == Cityscape and architecture == Amsterdam fans out south from the Amsterdam Centraal railway station and Damrak, the main street off the station. The oldest area of the town is known as De Wallen (English: "The Quays"). It lies to the east of Damrak and contains the city's famous red light district. To the south of de Wallen is the old Jewish quarter of Waterlooplein. The medieval and colonial age canals of Amsterdam, known as grachten, embraces the heart of the city where homes have interesting gables. Beyond the Grachtengordel are the former working class areas of Jordaan and de Pijp. The Museumplein with the city's major museums, the Vondelpark, a 19th-century park named after the Dutch writer Joost van den Vondel, and the Plantage neighbourhood, with the zoo, are also located outside the Grachtengordel. Several parts of the city and the surrounding urban area are polders. This can be recognised by the suffix -meer which means lake, as in Aalsmeer, Bijlmermeer, Haarlemmermeer, and Watergraafsmeer. === Canals === The Amsterdam canal system is the result of conscious city planning. In the early 17th century, when immigration was at a peak, a comprehensive plan was developed that was based on four concentric half-circles of canals with their ends emerging at the IJ bay. Known as the Grachtengordel, three of the canals were mostly for residential development: the Herengracht (where "Heren" refers to Heren Regeerders van de stad Amsterdam (ruling lords of Amsterdam), and gracht means canal, so the name can be roughly translated as "Canal of the Lords"), Keizersgracht (Emperor's Canal), and Prinsengracht (Prince's Canal). The fourth and outermost canal is the Singelgracht, which is often not mentioned on maps, because it is a collective name for all canals in the outer ring. The Singelgracht should not be confused with the oldest and most inner canal Singel. The canals served for defence, water management and transport. The defences took the form of a moat and earthen dikes, with gates at transit points, but otherwise no masonry superstructures. The original plans have been lost, so historians, such as Ed Taverne, need to speculate on the original intentions: it is thought that the considerations of the layout were purely practical and defensive rather than ornamental.Construction started in 1613 and proceeded from west to east, across the breadth of the layout, like a gigantic windshield wiper as the historian Geert Mak calls it – and not from the centre outwards, as a popular myth has it. The canal construction in the southern sector was completed by 1656. Subsequently, the construction of residential buildings proceeded slowly. The eastern part of the concentric canal plan, covering the area between the Amstel river and the IJ bay, has never been implemented. In the following centuries, the land was used for parks, senior citizens' homes, theatres, other public facilities, and waterways without much planning. Over the years, several canals have been filled in, becoming streets or squares, such as the Nieuwezijds Voorburgwal and the Spui. === Expansion === After the development of Amsterdam's canals in the 17th century, the city did not grow beyond its borders for two centuries. During the 19th century, Samuel Sarphati devised a plan based on the grandeur of Paris and London at that time. The plan envisaged the construction of new houses, public buildings and streets just outside the Grachtengordel. The main aim of the plan, however, was to improve public health. Although the plan did not expand the city, it did produce some of the largest public buildings to date, like the Paleis voor Volksvlijt.Following Sarphati, civil engineers Jacobus van Niftrik and Jan Kalff designed an entire ring of 19th-century neighbourhoods surrounding the city's centre, with the city preserving the ownership of all land outside the 17th-century limit, thus firmly controlling development. Most of these neighbourhoods became home to the working class.In response to overcrowding, two plans were designed at the beginning of the 20th century which were very different from anything Amsterdam had ever seen before: Plan Zuid, designed by the architect Berlage, and West. These plans involved the development of new neighbourhoods consisting of housing blocks for all social classes.After the Second World War, large new neighbourhoods were built in the western, southeastern, and northern parts of the city. These new neighbourhoods were built to relieve the city's shortage of living space and give people affordable houses with modern conveniences. The neighbourhoods consisted mainly of large housing blocks situated among green spaces, connected to wide roads, making the neighbourhoods easily accessible by motor car. The western suburbs which were built in that period are collectively called the Westelijke Tuinsteden. The area to the southeast of the city built during the same period is known as the Bijlmer. === Architecture === Amsterdam has a rich architectural history. The oldest building in Amsterdam is the Oude Kerk (English: Old Church), at the heart of the Wallen, consecrated in 1306. The oldest wooden building is Het Houten Huys at the Begijnhof. It was constructed around 1425 and is one of only two existing wooden buildings. It is also one of the few examples of Gothic architecture in Amsterdam. In the 16th century, wooden buildings were razed and replaced with brick ones. During this period, many buildings were constructed in the architectural style of the Renaissance. Buildings of this period are very recognisable with their stepped gable façades, which is the common Dutch Renaissance style. Amsterdam quickly developed its own Renaissance architecture. These buildings were built according to the principles of the architect Hendrick de Keyser. One of the most striking buildings designed by Hendrick de Keyer is the Westerkerk. In the 17th century baroque architecture became very popular, as it was elsewhere in Europe. This roughly coincided with Amsterdam's Golden Age. The leading architects of this style in Amsterdam were Jacob van Campen, Philips Vingboons and Daniel Stalpaert.Philip Vingboons designed splendid merchants' houses throughout the city. A famous building in baroque style in Amsterdam is the Royal Palace on Dam Square. Throughout the 18th century, Amsterdam was heavily influenced by French culture. This is reflected in the architecture of that period. Around 1815, architects broke with the baroque style and started building in different neo-styles. Most Gothic style buildings date from that era and are therefore said to be built in a neo-gothic style. At the end of the 19th century, the Jugendstil or Art Nouveau style became popular and many new buildings were constructed in this architectural style. Since Amsterdam expanded rapidly during this period, new buildings adjacent to the city centre were also built in this style. The houses in the vicinity of the Museum Square in Amsterdam Oud-Zuid are an example of Jugendstil. The last style that was popular in Amsterdam before the modern era was Art Deco. Amsterdam had its own version of the style, which was called the Amsterdamse School. Whole districts were built this style, such as the Rivierenbuurt. A notable feature of the façades of buildings designed in Amsterdamse School is that they are highly decorated and ornate, with oddly shaped windows and doors. The old city centre is the focal point of all the architectural styles before the end of the 19th century. Jugendstil and Georgian are mostly found outside the city's centre in the neighbourhoods built in the early 20th century, although there are also some striking examples of these styles in the city centre. Most historic buildings in the city centre and nearby are houses, such as the famous merchants' houses lining the canals. === Parks and recreational areas === Amsterdam has many parks, open spaces, and squares throughout the city. Vondelpark, the largest park in the city, is located in the Oud-Zuid borough and is named after the 17th century Amsterdam author, Joost van den Vondel. Yearly, the park has around 10 million visitors. In the park is an open-air theatre, a playground and several horeca facilities. In the Zuid borough, is Beatrixpark, named after Queen Beatrix. Between Amsterdam and Amstelveen is the Amsterdamse Bos ("Amsterdam Forest"), the largest recreational area in Amsterdam. Annually, almost 4.5 million people visit the park, which has a size of 1.000 hectares and is approximately three times the size of Central Park. Amstelpark in the Zuid borough houses the Rieker windmill, which dates to 1636. Other parks include Sarphatipark in the De Pijp neighbourhood, Oosterpark in the Oost borough, and Westerpark in the Westerpark neighbourhood. The city has three beaches: Nemo Beach, Citybeach "Het stenen hoofd" (Silodam) and Blijburg, all located in the Centrum borough. The city has many open squares (plein in Dutch). The namesake of the city as the site of the original dam, Dam Square, is the main town square and has the Royal Palace and National Monument. Museumplein hosts various museums, including the Rijksmuseum, Van Gogh Museum, and Stedelijk Museum. Other squares include Rembrandtplein, Muntplein, Nieuwmarkt, Leidseplein, Spui, and Waterlooplein. Also, near to Amsterdam is the Nekkeveld estate conservation project. == Economy == Amsterdam is the financial and business capital of the Netherlands. Amsterdam is ranked fifth best of European cities in which to locate an international business, surpassed by London, Paris, Frankfurt and Barcelona. Many large corporations and banks have their headquarters in Amsterdam, including AkzoNobel, Heineken International, ING Group, ABN AMRO, TomTom, Delta Lloyd Group, Booking.com and Philips. KPMG International's global headquarters is located in nearby Amstelveen, where many non-Dutch companies have settled as well, because surrounding communities allow full land ownership, contrary to Amsterdam's land-lease system. Though many small offices are still located on the old canals, companies are increasingly relocating outside the city centre. The Zuidas (English: South Axis) has become the new financial and legal hub. The five largest law firms of the Netherlands, a number of Dutch subsidiaries of large consulting firms like Boston Consulting Group and Accenture, and the World Trade Center Amsterdam are also located in Zuidas. There are three other smaller financial districts in Amsterdam. The first is the area surrounding Amsterdam Sloterdijk railway station, where several newspapers like De Telegraaf have their offices. Also, Deloitte, the Gemeentelijk Vervoerbedrijf (municipal public transport company) and the Dutch tax offices (Belastingdienst) are located there. The second Financial District is the area surrounding the Amsterdam Arena. The third is the area surrounding Amsterdam Amstel railway station. The tallest building in Amsterdam, the Rembrandt Tower, is situated there, as is the headquarters of Philips. === Port of Amsterdam === The Port of Amsterdam is the fourth largest port in Europe, the 38th largest port in the world and the second largest port in the Netherlands by metric tons of cargo. In 2014 the Port of Amsterdam had a cargo throughput of 97,4 million tons of cargo, which was mostly bulk cargo. Amsterdam has the biggest cruise port in the Netherlands with more than 150 cruise ships every year. In 2019 the new lock in IJmuiden will open; the port will then be able to grow to 125 million tonnes in capacity. The Amsterdam Stock Exchange (AEX), now part of Euronext, is the world's oldest stock exchange and is one of Europe's largest bourses. It is near Dam Square in the city centre. Together with Eindhoven (Brainport) and Rotterdam (Seaport), Amsterdam (Airport) forms the foundation of the Dutch economy. === Tourism === Amsterdam is one of the most popular tourist destinations in Europe, receiving more than 4.63 million international visitors annually, this is excluding the 16 million day trippers visiting the city every year. The number of visitors has been growing steadily over the past decade. This can be attributed to an increasing number of European visitors. Two-thirds of the hotels are located in the city's centre. Hotels with 4 or 5 stars contribute 42% of the total beds available and 41% of the overnight stays in Amsterdam. The room occupation rate was 78% in 2006, up from 70% in 2005. The majority of tourists (74%) originate from Europe. The largest group of non-European visitors come from the United States, accounting for 14% of the total. Certain years have a theme in Amsterdam to attract extra tourists. For example, the year 2006 was designated "Rembrandt 400", to celebrate the 400th birthday of Rembrandt van Rijn. Some hotels offer special arrangements or activities during these years. The average number of guests per year staying at the four campsites around the city range from 12,000 to 65,000. ==== Red light district ==== De Wallen, also known as Walletjes or Rosse Buurt, is a designated area for legalised prostitution and is Amsterdam's largest and most well known red-light district. This neighbourhood has become a famous attraction for tourists. It consists of a network of roads and alleys containing several hundred small, one-room apartments rented by sex workers who offer their services from behind a window or glass door, typically illuminated with red lights. === Retail === Shops in Amsterdam range from large high end department stores such as De Bijenkorf founded in 1870 to small specialty shops. Amsterdam's high-end shops are found in the streets P.C. Hooftstraat and Cornelis Schuytstraat, which are located in the vicinity of the Vondelpark. One of Amsterdam's busiest high streets is the narrow, medieval Kalverstraat in the heart of the city. Other shopping areas include the Negen Straatjes and Haarlemmerdijk and Haarlemmerstraat. Negen Straatjes are nine narrow streets within the Grachtengordel, the concentric canal system of Amsterdam. The Negen Straatjes differ from other shopping districts with the presence of a large diversity of privately owned shops. The Haarlemmerstraat and Haarlemmerdijk were voted best shopping street in the Netherlands in 2011. These streets have as the Negen Straatjes a large diversity of privately owned shops. But as the Negen Straatjes are dominated by fashion stores the Haarlemmerstraat and Haarlemmerdijk offer a very wide variety of all kinds of stores, just to name some specialties: candy and other food related stores, lingerie, sneakers, wedding clothing, interior shops, books, Italian deli's, racing and mountain bikes, skatewear, etc. The city also features a large number of open-air markets such as the Albert Cuyp Market, Westerstraat-markt, Ten Katemarkt, and Dappermarkt. Some of these markets are held on a daily basis, like the Albert Cuypmarkt and the Dappermarkt. Others, like the Westerstraatmarkt, are held on a weekly basis. === Fashion === Fashion brands like G-star, Gsus, BlueBlood, PICHICHI, Iris van Herpen, fair trade denim brand MUD Jeans, 10 feet and Warmenhoven & Venderbos, and fashion designers like Mart Visser, Viktor & Rolf, Sheila de Vries, Marlies Dekkers and Frans Molenaar are based in Amsterdam. Modelling agencies Elite Models, Touche models and Tony Jones have opened branches in Amsterdam. Fashion models like Yfke Sturm, Doutzen Kroes and Kim Noorda started their careers in Amsterdam. Amsterdam has its garment centre in the World Fashion Center. Buildings which formerly housed brothels in the red light district have been converted to ateliers for young fashion designers, AKA eagle fuel. Fashion photographers Inez van Lamsweerde and Vinoodh Matadin were born in Amsterdam(Netherland). == Culture == During the later part of the 16th-century Amsterdam's Rederijkerskamer (Chamber of rhetoric) organised contests between different Chambers in the reading of poetry and drama. In 1638, Amsterdam opened its first theatre. Ballet performances were given in this theatre as early as 1642. In the 18th century, French theatre became popular. While Amsterdam was under the influence of German music in the 19th century there were few national opera productions; the Hollandse Opera of Amsterdam was built in 1888 for the specific purpose of promoting Dutch opera. In the 19th century, popular culture was centred on the Nes area in Amsterdam (mainly vaudeville and music-hall). The metronome, one of the most important advances in European classical music, was invented here in 1812 by Dietrich Nikolaus Winkel. At the end of this century, the Rijksmuseum and Stedelijk Museum were built. In 1888, the Concertgebouworkest was established. With the 20th century came cinema, radio and television. Though most studios are located in Hilversum and Aalsmeer, Amsterdam's influence on programming is very strong. Many people who work in the television industry live in Amsterdam. Also, the headquarters of the Dutch SBS Broadcasting Group is located in Amsterdam. === Museums === The most important museums of Amsterdam are located on the Museumplein (Museum Square), located at the southwestern side of the Rijksmuseum. It was created in the last quarter of the 19th century on the grounds of the former World's fair. The northeastern part of the square is bordered by the very large Rijksmuseum. In front of the Rijksmuseum on the square itself is a long, rectangular pond. This is transformed into an ice rink in winter. The northwestern part of the square is bordered by the Van Gogh Museum, Stedelijk Museum, House of Bols Cocktail & Genever Experience and Coster Diamonds. The southwestern border of the Museum Square is the Van Baerlestraat, which is a major thoroughfare in this part of Amsterdam. The Concertgebouw is situated across this street from the square. To the southeast of the square are situated a number of large houses, one of which contains the American consulate. A parking garage can be found underneath the square, as well as a supermarket. The Museumplein is covered almost entirely with a lawn, except for the northeastern part of the square which is covered with gravel. The current appearance of the square was realised in 1999, when the square was remodelled. The square itself is the most prominent site in Amsterdam for festivals and outdoor concerts, especially in the summer. Plans were made in 2008 to remodel the square again, because many inhabitants of Amsterdam are not happy with its current appearance. The Rijksmuseum possesses the largest and most important collection of classical Dutch art. It opened in 1885. Its collection consists of nearly one million objects. The artist most associated with Amsterdam is Rembrandt, whose work, and the work of his pupils, is displayed in the Rijksmuseum. Rembrandt's masterpiece The Night Watch is one of top pieces of art of the museum. It also houses paintings from artists like Van der Helst, Vermeer, Frans Hals, Ferdinand Bol, Albert Cuyp, Jacob van Ruisdael and Paulus Potter. Aside from paintings, the collection consists of a large variety of decorative art. This ranges from Delftware to giant doll-houses from the 17th century. The architect of the gothic revival building was P.J.H. Cuypers. The museum underwent a 10-year, 375 million euro renovation starting in 2003. The full collection was reopened to the public on 13 April 2013 and the Rijksmuseum has established itself as the most visited museum in Amsterdam with 2.2 million visitors in 2013.Van Gogh lived in Amsterdam for a short while and there is a museum dedicated to his work. The museum is housed in one of the few modern buildings in this area of Amsterdam. The building was designed by Gerrit Rietveld. This building is where the permanent collection is displayed. A new building was added to the museum in 1999. This building, known as the performance wing, was designed by Japanese architect Kisho Kurokawa. Its purpose is to house temporary exhibitions of the museum. Some of Van Gogh's most famous paintings, like The Potato Eaters and Sunflowers, are in the collection. The Van Gogh museum is the second most visited museum in Amsterdam, with 1.4 million annual visitors.Next to the Van Gogh museum stands the Stedelijk Museum. This is Amsterdam's most important museum of modern art. The museum is as old as the square it borders and was opened in 1895. The permanent collection consists of works of art from artists like Piet Mondriaan, Karel Appel, and Kazimir Malevich. After renovations lasting several years the museum opened in September 2012 with a new composite extension that has been called 'The Bathtub' due to its resemblance to one. Amsterdam contains many other museums throughout the city. They range from small museums such as the Verzetsmuseum (Resistance Museum), the Anne Frank House, and the Rembrandt House Museum, to the very large, like the Tropenmuseum (Museum of the Tropics), Amsterdam Museum (formerly known as Amsterdam Historical Museum), Hermitage Amsterdam (a dependency of the Hermitage Museum in Saint Petersburg) and the Joods Historisch Museum (Jewish Historical Museum). The modern-styled Nemo is dedicated to child-friendly science exhibitions. === Music === Amsterdam's musical culture includes a large collection of songs which treat the city nostalgically and lovingly. The 1949 song "Aan de Amsterdamse grachten" ("On the canals of Amsterdam") was performed and recorded by many artists, including John Kraaijkamp Sr.; the best-known version is probably that by Wim Sonneveld (1962). In the 1950s Johnny Jordaan rose to fame with "Geef mij maar Amsterdam" ("I prefer Amsterdam"), which praises the city above all others (explicitly Paris); Jordaan sang especially about his own neighbourhood, the Jordaan ("Bij ons in de Jordaan"). Colleagues and contemporaries of Johnny include Tante Leen and Manke Nelis. Other notable Amsterdam songs are "Amsterdam" by Jacques Brel (1964) and "Deze Stad" by De Dijk (1989). A 2011 poll by Amsterdam newspaper Het Parool that Trio Bier's "Oude Wolf" was voted "Amsterdams lijflied". Notable Amsterdam bands from the modern era include the Osdorp Posse and The Ex. AFAS Live (formerly known as the Heineken Music Hall) is a concert hall located near the Johan Cruyff Arena (known as the Amsterdam Arena until 2017). Its main purpose is to serve as a podium for pop concerts for big audiences. Many famous international artists have performed there. Two other notable venues, Paradiso and the Melkweg are located near the Leidseplein. Both focus on broad programming, ranging from indie rock to hip hop, R&B, and other popular genres. Other more subcultural music venues are OCCII, OT301, De Nieuwe Anita, Winston Kingdom and Zaal 100. Jazz has a strong following in Amsterdam, with the Bimhuis being the premier venue. In 2012, Ziggo Dome was opened, also near Amsterdam Arena, a state-of-the-art indoor music arena. AFAS Live is also host to many electronic dance music festivals, alongside many other venues. Armin van Buuren and Tiesto, some of the world's leading Trance DJ's hail from the Netherlands and perform frequently in Amsterdam. Each year in October, the city hosts the Amsterdam Dance Event (ADE) which is one of the leading electronic music conferences and one of the biggest club festivals for electronic music in the world, attracting over 350,000 visitors each year. Another popular dance festival is 5daysoff, which takes place in the venues Paradiso and Melkweg. In summer time there are several big outdoor dance parties in or nearby Amsterdam, such as Awakenings, Dance Valley, Mystery Land, Loveland, A Day at the Park, Welcome to the Future, and Valtifest. Amsterdam has a world-class symphony orchestra, the Royal Concertgebouw Orchestra. Their home is the Concertgebouw, which is across the Van Baerlestraat from the Museum Square. It is considered by critics to be a concert hall with some of the best acoustics in the world. The building contains three halls, Grote Zaal, Kleine Zaal, and Spiegelzaal. Some nine hundred concerts and other events per year take place in the Concertgebouw, for a public of over 700,000, making it one of the most-visited concert halls in the world. The opera house of Amsterdam is situated adjacent to the city hall. Therefore, the two buildings combined are often called the Stopera, (a word originally coined by protesters against it very construction: Stop the Opera[-house]). This huge modern complex, opened in 1986, lies in the former Jewish neighbourhood at Waterlooplein next to the river Amstel. The Stopera is the homebase of Dutch National Opera, Dutch National Ballet and the Holland Symfonia. Muziekgebouw aan 't IJ is a concert hall, which is situated in the IJ near the central station. Its concerts perform mostly modern classical music. Located adjacent to it, is the Bimhuis, a concert hall for improvised and Jazz music. === Performing arts === Amsterdam has three main theatre buildings. The Stadsschouwburg at the Leidseplein is the home base of Toneelgroep Amsterdam. The current building dates from 1894. Most plays are performed in the Grote Zaal (Great Hall). The normal programme of events encompasses all sorts of theatrical forms. The Stadsschouwburg is currently being renovated and expanded. The third theatre space, to be operated jointly with next door Melkweg, will open in late 2009 or early 2010. The Dutch National Opera and Ballet (formerly known as Het Muziektheater), dating from 1986, is the principal opera house and home to Dutch National Opera and Dutch National Ballet. Royal Theatre Carré was built as a permanent circus theatre in 1887 and is currently mainly used for musicals, cabaret performances and pop concerts. The recently re-opened DeLaMar Theater houses the more commercial plays and musicals. A new theatre has also moved into Amsterdam scene in 2014, joining other established venues: Theater Amsterdam is situated in the west part of Amsterdam, on the Danzigerkade. It is housed in a modern building with a panoramic view over the harbour. The theatre is the first ever purpose-built venue to showcase a single play entitled ANNE, the play based on Anne Frank's life. On the east side of town there is a small theatre in a converted bath house, the Badhuistheater. The theatre often has English programming. The Netherlands has a tradition of cabaret or kleinkunst, which combines music, storytelling, commentary, theatre and comedy. Cabaret dates back to the 1930s and artists like Wim Kan, Wim Sonneveld and Toon Hermans were pioneers of this form of art in the Netherlands. In Amsterdam is the Kleinkunstacademie (English: Cabaret Academy). Contemporary popular artists are Youp van 't Hek, Freek de Jonge, Herman Finkers, Hans Teeuwen, Theo Maassen, Herman van Veen, Najib Amhali, Raoul Heertje, Jörgen Raymann, Brigitte Kaandorp and Comedytrain. The English spoken comedy scene was established with the founding of Boom Chicago in 1993. They have their own theatre at Leidseplein. === Nightlife === Amsterdam is famous for its vibrant and diverse nightlife. Amsterdam has many cafés (bars). They range from large and modern to small and cozy. The typical Bruine Kroeg (brown café) breathe a more old fashioned atmosphere with dimmed lights, candles, and somewhat older clientele. Most cafés have terraces in summertime. A common sight on the Leidseplein during summer is a square full of terraces packed with people drinking beer or wine. Many restaurants can be found in Amsterdam as well. Since Amsterdam is a multicultural city, a lot of different ethnic restaurants can be found. Restaurants range from being rather luxurious and expensive to being ordinary and affordable. Amsterdam also possesses many discothèques. The two main nightlife areas for tourists are the Leidseplein and the Rembrandtplein. The Paradiso, Melkweg and Sugar Factory are cultural centres, which turn into discothèques on some nights. Examples of discothèques near the Rembrandtplein are the Escape, Air, John Doe and Club Abe. Also noteworthy are Panama, Hotel Arena (East), TrouwAmsterdam and Studio 80. Bimhuis located near the Central Station, with its rich programming hosting the best in the field is considered one of the best jazz clubs in the world. The Reguliersdwarsstraat is the main street for the LGBT community and nightlife. === Festivals === In 2008, there were 140 festivals and events in Amsterdam.Famous festivals and events in Amsterdam include: Koningsdag (which was named Koninginnedag until the crowning of King Willem-Alexander in 2013) (King's Day – Queen's Day); the Holland Festival for the performing arts; the yearly Prinsengrachtconcert (classical concerto on the Prinsen canal) in August; the 'Stille Omgang' (a silent Roman Catholic evening procession held every March); Amsterdam Gay Pride; The Cannabis Cup; and the Uitmarkt. On Koninginnedag—that was held each year on 30 April—hundreds of thousands of people travel to Amsterdam to celebrate with the city's residents and Koningsdag is held on 27 April. The entire city becomes overcrowded with people buying products from the freemarket, or visiting one of the many music concerts. The yearly Holland Festival attracts international artists and visitors from all over Europe. Amsterdam Gay Pride is a yearly local LGBT parade of boats in Amsterdam's canals, held on the first Saturday in August. The annual Uitmarkt is a three-day cultural event at the start of the cultural season in late August. It offers previews of many different artists, such as musicians and poets, who perform on podia. === Sports === Amsterdam is home of the Eredivisie football club AFC Ajax. The stadium Johan Cruyff Arena is the home of Ajax. It is located in the south-east of the city next to the new Amsterdam Bijlmer ArenA railway station. Before moving to their current location in 1996, Ajax played their regular matches in De Meer Stadion. In 1928, Amsterdam hosted the Summer Olympics. The Olympic Stadium built for the occasion has been completely restored and is now used for cultural and sporting events, such as the Amsterdam Marathon. In 1920, Amsterdam assisted in hosting some of the sailing events for the Summer Olympics held in neighbouring Antwerp, Belgium by hosting events at Buiten Y. The city holds the Dam to Dam Run, a 16-kilometre (10 mi) race from Amsterdam to Zaandam, as well as the Amsterdam Marathon. The ice hockey team Amstel Tijgers play in the Jaap Eden ice rink. The team competes in the Dutch ice hockey premier league. Speed skating championships have been held on the 400-metre lane of this ice rink. Amsterdam holds two American football franchises: the Amsterdam Crusaders and the Amsterdam Panthers. The Amsterdam Pirates baseball team competes in the Dutch Major League. There are three field hockey teams: Amsterdam, Pinoké and Hurley, who play their matches around the Wagener Stadium in the nearby city of Amstelveen. The basketball team MyGuide Amsterdam competes in the Dutch premier division and play their games in the Sporthallen Zuid.There is one rugbyclub in Amsterdam, which also hosts sports training classes such as RTC(Rugby Talenten Centrum or Rugby Talent Centre) and the National Rugby stadium. Since 1999 the city of Amsterdam honours the best sportsmen and women at the Amsterdam Sports Awards. Boxer Raymond Joval and field hockey midfielder Carole Thate were the first to receive the awards, in 1999. == Government == The city of Amsterdam is a municipality under the Dutch Municipalities Act. It is governed by a directly elected municipal council, a municipal executive board and a mayor. Since 1981, the municipality of Amsterdam has gradually been divided into semi-autonomous boroughs, called stadsdelen or 'districts'. Over time, a total of 15 boroughs were created. In May 2010, under a major reform, the number of Amsterdam boroughs was reduced to eight: Amsterdam-Centrum covering the city centre including the canal belt, Amsterdam-Noord consisting of the neighbourhoods north of the IJ lake, Amsterdam-Oost in the east, Amsterdam-Zuid in the south, Amsterdam-West in the west, Amsterdam Nieuw-West in the far west, Amsterdam Zuidoost in the southeast, and Westpoort covering the Port of Amsterdam area. === City government === As with all Dutch municipalities, Amsterdam is governed by a directly elected municipal council, a municipal executive board and a mayor (burgemeester). The mayor is a member of the municipal executive board, but also has individual responsibilies in maintaining public order. On 27 June 2018 Femke Halsema (former member of House of Representatives for GroenLinks from 1998 to 2011) was appointed as the first women to be Mayor of Amsterdam by the King's Commissioner of North Holland for a six-year term after being nominated by the Amsterdam municipal council. and began serving a six-year term on 12 July 2018. She replaces Eberhard van der Laan (Labour Party) who was the Mayor of Amsterdam from 2010 until his death in October 2017. After the 2014 municipal council elections, a governing majority of D66, VVD and SP was formed – the first coalition without the Labour Party since World War II. Next to the Mayor, the municipal executive board consists of eight wethouders ('alderpersons') appointed by the municipal council: four D66 alderpersons, two VVD alderpersons and two SP alderpersons.On 18 September 2017 it was announced by Eberhard van der Laan in an open letter to Amsterdam citizens that Kajsa Ollongren would take up his office as acting Mayor of Amsterdam with immediate effect due to ill health. Ollongren was succeeded as acting Mayor by Eric van der Burg on 26 October 2017 and by Jozias van Aartsen on 4 December 2017. Unlike most other Dutch municipalities, Amsterdam is subdivided into eight boroughs, called stadsdelen or 'districts', a system that was implemented gradually in the 1980s to improve local governance. The boroughs are responsible for many activities that had previously been run by the central city. In 2010, the number of Amsterdam boroughs reached fifteen. Fourteen of those had their own district council (deelraad), elected by a popular vote. The fifteenth, Westpoort, covers the harbour of Amsterdam and had very few residents. Therefore, it was governed by the central municipal council. Under the borough system, municipal decisions are made at borough level, except for those affairs pertaining to the whole city such as major infrastructure projects, which are the jurisdiction of the central municipal authorities. In 2010, the borough system was restructured, in which many smaller boroughs merged into larger boroughs. In 2014, under a reform of the Dutch Municipalities Act, the Amsterdam boroughs lost much of their autonomous status, as their district councils were abolished. The municipal council of Amsterdam voted to maintain the borough system by replacing the district councils with smaller, but still directly elected district committees (bestuurscommissies). Under a municipal ordinance, the new district committees were granted responsibilities through delegation of regulatory and executive powers by the central municipal council. === Metropolitan area === "Amsterdam" is usually understood to refer to the municipality of Amsterdam. Colloquially, some areas within the municipality, such as the town of Durgerdam, may not be considered part of Amsterdam. Statistics Netherlands uses three other definitions of Amsterdam: metropolitan agglomeration Amsterdam (Grootstedelijke Agglomeratie Amsterdam, not to be confused with Grootstedelijk Gebied Amsterdam, a synonym of Groot Amsterdam), Greater Amsterdam (Groot Amsterdam, a COROP region) and the urban region Amsterdam (Stadsgewest Amsterdam). The Amsterdam Department for Research and Statistics uses a fourth conurbation, namely the Stadsregio Amsterdam ('City Region of Amsterdam'). The city region is similar to Greater Amsterdam but includes the municipalities of Zaanstad and Wormerland. It excludes Graft-De Rijp. The smallest of these areas is the municipality of Amsterdam with a population of 802,938 in 2013. The conurbation had a population of 1,096,042 in 2013. It includes the municipalities of Zaanstad, Wormerland, Oostzaan, Diemen and Amstelveen only, as well as the municipality of Amsterdam. Greater Amsterdam includes 15 municipalities, and had a population of 1,293,208 in 2013. Though much larger in area, the population of this area is only slightly larger, because the definition excludes the relatively populous municipality of Zaanstad. The largest area by population, the Amsterdam Metropolitan Area (Dutch: Metropoolregio Amsterdam), has a population of 2,33 million. It includes for instance Zaanstad, Wormerveer, Muiden, Abcoude, Haarlem, Almere and Lelystad but excludes Graft-De Rijp. Amsterdam is part of the conglomerate metropolitan area Randstad, with a total population of 6,659,300 inhabitants.Of these various metropolitan area configurations, only the Stadsregio Amsterdam (City Region of Amsterdam) has a formal governmental status. Its responsibities include regional spatial planning and the metropolitan public transport concessions. === National capital === Under the Dutch Constitution, Amsterdam is the capital of the Netherlands. Since the 1983 constitutional revision, the constitution mentions "Amsterdam" and "capital" in chapter 2, article 32: The king's confirmation by oath and his coronation take place in "the capital Amsterdam" ("de hoofdstad Amsterdam"). Previous versions of the constitution only mentioned "the city of Amsterdam" ("de stad Amsterdam"). For a royal investiture, therefore, the States General of the Netherlands (the Dutch Parliament) meets for a ceremonial joint session in Amsterdam. The ceremony traditionally takes place at the Nieuwe Kerk on Dam Square, immediately after the former monarch has signed the act of abdication at the nearby Royal Palace of Amsterdam. Normally, however, the Parliament sits in The Hague, the city which has historically been the seat of the Dutch government, the Dutch monarchy, and the Dutch supreme court. Foreign embassies are also located in The Hague. === Symbols === The coat of arms of Amsterdam is composed of several historical elements. First and centre are three St Andrew's crosses, aligned in a vertical band on the city's shield (although Amsterdam's patron saint was Saint Nicholas). These St Andrew's crosses can also be found on the cityshields of neighbours Amstelveen and Ouder-Amstel. This part of the coat of arms is the basis of the flag of Amsterdam, flown by the city government, but also as civil ensign for ships registered in Amsterdam. Second is the Imperial Crown of Austria. In 1489, out of gratitude for services and loans, Maximilian I awarded Amsterdam the right to adorn its coat of arms with the king's crown. Then, in 1508, this was replaced with Maximilian's imperial crown when he was crowned Holy Roman Emperor. In the early years of the 17th century, Maximilian's crown in Amsterdam's coat of arms was again replaced, this time with the crown of Emperor Rudolph II, a crown that became the Imperial Crown of Austria. The lions date from the late 16th century, when city and province became part of the Republic of the Seven United Netherlands. Last came the city's official motto: Heldhaftig, Vastberaden, Barmhartig ("Heroic, Determined, Merciful"), bestowed on the city in 1947 by Queen Wilhelmina, in recognition of the city's bravery during the Second World War. == Transport == === Metro, tram and bus === Currently, there are sixteen tram routes and four metro routes, with a fifth route to be added when completed (due in July 2018). All are operated by municipal public transport operator GVB, which also runs the city bus network. Four fare-free GVB ferries carry pedestrians and cyclists across the IJ lake to the borough of Amsterdam-Noord, and two fare-charging ferries run east and west along the harbour. There are also privately operated water taxis, a water bus, a boat sharing operation, electric rental boats and canal cruises, that transport people along Amsterdam's waterways. Regional buses, and some suburban buses, are operated by Connexxion and EBS. International coach services are provided by Eurolines from Amsterdam Amstel railway station, IDBUS from Amsterdam Sloterdijk railway station, and Megabus from the Zuiderzeeweg in the east of the city. In order to facilitate easier transport to the center of Amsterdam, the city has various P+R Locations where people can park their car at an affordable price and transfer to one of the numerous public transport lines. === Car === Amsterdam was intended in 1932 to be the hub, a kind of Kilometre Zero, of the highway system of the Netherlands, with freeways numbered One to Eight planned to originate from the city. The outbreak of the Second World War and shifting priorities led to the current situation, where only roads A1, A2, and A4 originate from Amsterdam according to the original plan. The A3 to Rotterdam was cancelled in 1970 in order to conserve the Groene Hart. Road A8, leading north to Zaandam and the A10 Ringroad were opened between 1968 and 1974. Besides the A1, A2, A4 and A8, several freeways, such as the A7 and A6, carry traffic mainly bound for Amsterdam. The A10 ringroad surrounding the city connects Amsterdam with the Dutch national network of freeways. Interchanges on the A10 allow cars to enter the city by transferring to one of the 18 city roads, numbered S101 through to S118. These city roads are regional roads without grade separation, and sometimes without a central reservation. Most are accessible by cyclists. The S100 Centrumring is a smaller ringroad circumnavigating the city's centre. In the city centre, driving a car is discouraged. Parking fees are expensive, and many streets are closed to cars or are one-way. The local government sponsors carsharing and carpooling initiatives such as Autodelen and Meerijden.nu. === National rail === Amsterdam is served by ten stations of the Nederlandse Spoorwegen (Dutch Railways). Five are intercity stops: Sloterdijk, Zuid, Amstel, Bijlmer ArenA and Amsterdam Centraal. The stations for local services are: Lelylaan, RAI, Holendrecht, Muiderpoort and Science Park. Amsterdam Centraal is also an international railway station. From the station there are regular services to destinations such as Austria, Belarus, Belgium, the Czech Republic, Denmark, France, Germany, Hungary, Poland, Russia, Switzerland and the United Kingdom. Among these trains are international trains of the Nederlandse Spoorwegen (Amsterdam-Berlin), the Eurostar (Amsterdam-Brussels-London), Thalys (Amsterdam-Brussels-Paris/Lille), and InterCityExpress (Amsterdam–Cologne–Frankfurt). === Airport === Amsterdam Airport Schiphol is less than 20 minutes by train from Amsterdam Centraal station and is served by domestic and international intercity trains, such as Thalys and Intercity Brussel. Schiphol is the largest airport in the Netherlands, the third largest in Europe, and the 14th-largest in the world in terms of passengers. It handles over 60 million passengers per year and is the home base of four airlines, KLM, Transavia, Martinair and Arkefly . As of 2014, Schiphol was the fifth busiest airport in the world measured by international passenger numbers. === Cycling === Amsterdam is one of the most bicycle-friendly large cities in the world and is a centre of bicycle culture with good facilities for cyclists such as bike paths and bike racks, and several guarded bike storage garages (fietsenstalling) which can be used. In 2013, there were about 1,200,000 bicycles in Amsterdam outnumbering the amount of citizens in the city. Theft is widespread—in 2011, about 83,000 bicycles were stolen in Amsterdam. Bicycles are used by all socio-economic groups because of their convenience, Amsterdam's small size, the 400 kilometres (249 miles) of bike paths, the flat terrain, and the inconvenience of driving an automobile. == Education == Amsterdam has two universities: the University of Amsterdam (Universiteit van Amsterdam, UvA), and the Vrije Universiteit Amsterdam (VU). Other institutions for higher education include an art school – Gerrit Rietveld Academie, a university of applied sciences – the Hogeschool van Amsterdam, and the Amsterdamse Hogeschool voor de Kunsten. Amsterdam's International Institute of Social History is one of the world's largest documentary and research institutions concerning social history, and especially the history of the labour movement. Amsterdam's Hortus Botanicus, founded in the early 17th century, is one of the oldest botanical gardens in the world, with many old and rare specimens, among them the coffee plant that served as the parent for the entire coffee culture in Central and South America.There are over 200 primary schools in Amsterdam. Some of these primary schools base their teachings on particular pedagogic theories like the various Montessori schools. The biggest Montessori high school in Amsterdam is the Montessori Lyceum Amsterdam. Many schools, however, are based on religion. This used to be primarily Roman Catholicism and various Protestant denominations, but with the influx of Muslim immigrants there has been a rise in the number of Islamic schools. Jewish schools can be found in the southern suburbs of Amsterdam. Amsterdam is noted for having five independent grammar schools (Dutch: gymnasia), the Vossius Gymnasium, Barlaeus Gymnasium, St. Ignatius Gymnasium, Het 4e Gymnasium and the Cygnus Gymnasium where a classical curriculum including Latin and classical Greek is taught. Though believed until recently by many to be an anachronistic and elitist concept that would soon die out, the gymnasia have recently experienced a revival, leading to the formation of a fourth and fifth grammar school in which the three aforementioned schools participate. Most secondary schools in Amsterdam offer a variety of different levels of education in the same school. The city also has various colleges ranging from art and design to politics and economics which are mostly also available for students coming from other countries. == Notable people == Frits Bolkestein (born 1933), politician Charlene de Carvalho-Heineken (born 1954), businesswoman Paul J.

Some locally based newspapers include Het Parool, a national daily paper; De Telegraaf, the largest Dutch daily newspaper; the daily newspapers Trouw, de Volkskrant and NRC Handelsblad; De Groene Amsterdammer, a weekly newspaper; the free newspapers Sp!ts, Metro, and The Holland Times (printed in English). Amsterdam is home to the second-largest Dutch commercial TV group SBS Broadcasting Group, consisting of TV-stations SBS 6, Net 5 and Veronica. However, Amsterdam is not considered 'the media city of the Netherlands'. The town of Hilversum, 30 kilometres (19 miles) south-east of Amsterdam, has been crowned with this unofficial title. Hilversum is the principal centre for radio and television broadcasting in the Netherlands. Radio Netherlands, heard worldwide via shortwave radio since the 1920s, is also based there. Hilversum is home to an extensive complex of audio and television studios belonging to the national broadcast production company NOS, as well as to the studios and offices of all the Dutch public broadcasting organisations and many commercial TV production companies. In 2012, the music video of Far East Movement, 'Live My Life', was filmed in various parts of Amsterdam. Also, several movies were filmed in Amsterdam, such as James Bond's Diamonds Are Forever, Ocean's Twelve, Girl with a Pearl Earring and The Hitman's Bodyguard. Amsterdam is also featured in John Green's book The Fault in Our Stars, which has been made into a film as well that partly takes place in Amsterdam. == Housing == The housing market is heavily regulated. In Amsterdam, 55% of existing housing and 30% of new housing is owned by Housing Associations, which are Government sponsored entities. Squat properties are common throughout Amsterdam, due to property law strongly favouring tenants. A number of these squats have become well known, such as OT301, Paradiso, Vrankrijk (closed down by city government), and the Binnenpret, and several are now businesses, such as health clubs and licensed restaurants. == See also == Amsterdammertje == Notes and references == === Literature === Berns, Jan; Daan, Jo (1993).

### Instruction: retrieve labels for this: Audi AG (German: [ˈʔaʊ̯diː ʔaːˈgeː] ( listen)) is a German automobile manufacturer that designs, engineers, produces, markets and distributes luxury vehicles. Audi is a member of the Volkswagen Group and has its roots at Ingolstadt, Bavaria, Germany. Audi-branded vehicles are produced in nine production facilities worldwide. The origins of the company are complex, going back to the early 20th century and the initial enterprises (Horch and the Audiwerke) founded by engineer August Horch; and two other manufacturers (DKW and Wanderer), leading to the foundation of Auto Union in 1932. The modern era of Audi essentially began in the 1960s when Auto Union was acquired by Volkswagen from Daimler-Benz. After relaunching the Audi brand with the 1965 introduction of the Audi F103 series, Volkswagen merged Auto Union with NSU Motorenwerke in 1969, thus creating the present day form of the company. The company name is based on the Latin translation of the surname of the founder, August Horch. "Horch", meaning "listen" in German, becomes "audi" in Latin. The four rings of the Audi logo each represent one of four car companies that banded together to create Audi's predecessor company, Auto Union. Audi's slogan is Vorsprung durch Technik, meaning "Being Ahead through Technology". However, Audi USA had used the slogan "Truth in Engineering" from 2007 to 2016, and have not used the slogan since 2016. Audi, along with BMW and Mercedes-Benz, is among the best-selling luxury automobile brands in the world. == History == === Birth of the company and its name === Automobile company Wanderer was originally established in 1885, later becoming a branch of Audi AG. Another company, NSU, which also later merged into Audi, was founded during this time, and later supplied the chassis for Gottlieb Daimler's four-wheeler.On 14 November 1899, August Horch (1868–1951) established the company A. Horch & Cie. in the Ehrenfeld district of Cologne. In 1902, he moved with his company to Reichenbach im Vogtland. On 10 May 1904, he founded the August Horch & Cie. Motorwagenwerke AG, a joint-stock company in Zwickau (State of Saxony). After troubles with Horch chief financial officer, August Horch left Motorwagenwerke and founded in Zwickau on 16 July 1909, his second company, the August Horch Automobilwerke GmbH. His former partners sued him for trademark infringement. The German Reichsgericht (Supreme Court) in Leipzig, eventually determined that the Horch brand belonged to his former company. Since August Horch was prohibited from using "Horch" as a trade name in his new car business, he called a meeting with close business friends, Paul and Franz Fikentscher from Zwickau. At the apartment of Franz Fikentscher, they discussed how to come up with a new name for the company. During this meeting, Franz's son was quietly studying Latin in a corner of the room. Several times he looked like he was on the verge of saying something but would just swallow his words and continue working, until he finally blurted out, "Father – audiatur et altera pars... wouldn't it be a good idea to call it audi instead of horch?" "Horch!" in German means "Hark!" or "hear", which is "Audi" in the singular imperative form of "audire" – "to listen" – in Latin. The idea was enthusiastically accepted by everyone attending the meeting. On 25 April 1910 the Audi Automobilwerke GmbH Zwickau (from 1915 on Audiwerke AG Zwickau) was entered in the company's register of Zwickau registration court. The first Audi automobile, the Audi Type A 10/22 hp (16 kW) Sport-Phaeton, was produced in the same year, followed by the successor Type B 10/28PS in the same year.Audi started with a 2,612 cc inline-four engine model Type A, followed by a 3,564 cc model, as well as 4,680 cc and 5,720 cc models. These cars were successful even in sporting events. The first six-cylinder model Type M, 4,655 cc appeared in 1924.August Horch left the Audiwerke in 1920 for a high position at the ministry of transport, but he was still involved with Audi as a member of the board of trustees. In September 1921, Audi became the first German car manufacturer to present a production car, the Audi Type K, with left-handed drive. Left-hand drive spread and established dominance during the 1920s because it provided a better view of oncoming traffic, making overtaking safer. === The merger of the four companies under the logo of four rings === In August 1928, Jørgen Rasmussen, the owner of Dampf-Kraft-Wagen (DKW), acquired the majority of shares in Audiwerke AG. In the same year, Rasmussen bought the remains of the U.S. automobile manufacturer Rickenbacker, including the manufacturing equipment for eight-cylinder engines. These engines were used in Audi Zwickau and Audi Dresden models that were launched in 1929. At the same time, six-cylinder and four-cylinder (the "four" with a Peugeot engine) models were manufactured. Audi cars of that era were luxurious cars equipped with special bodywork. In 1932, Audi merged with Horch, DKW, and Wanderer, to form Auto Union AG, Chemnitz. It was during this period that the company offered the Audi Front that became the first European car to combine a six-cylinder engine with front-wheel drive. It used a powertrain shared with the Wanderer, but turned 180-degrees, so that the drive shaft faced the front. Before World War II, Auto Union used the four interlinked rings that make up the Audi badge today, representing these four brands. However, this badge was used only on Auto Union racing cars in that period while the member companies used their own names and emblems. The technological development became more and more concentrated and some Audi models were propelled by Horch or Wanderer built engines. Reflecting the economic pressures of the time, Auto Union concentrated increasingly on smaller cars through the 1930s, so that by 1938 the company's DKW brand accounted for 17.9% of the German car market, while Audi held only 0.1%. After the final few Audis were delivered in 1939 the "Audi" name disappeared completely from the new car market for more than two decades. === Post-World War II === Like most German manufacturing, at the onset of World War II the Auto Union plants were retooled for military production, and were a target for allied bombing during the war which left them damaged. Overrun by the Soviet Army in 1945, on the orders of the Soviet Union military administration the factories were dismantled as part of war reparations. Following this, the company's entire assets were expropriated without compensation. On 17 August 1948, Auto Union AG of Chemnitz was deleted from the commercial register. These actions had the effect of liquidating Germany's Auto Union AG. The remains of the Audi plant of Zwickau became the VEB (for "People Owned Enterprise") Automobilwerk Zwickau or AWZ (in English: Automobile Works Zwickau). With no prospect of continuing production in Soviet-controlled East Germany, Auto Union executives began the process of relocating what was left of the company to West Germany. A site was chosen in Ingolstadt, Bavaria, to start a spare parts operation in late 1945, which would eventually serve as the headquarters of the reformed Auto Union in 1949. The former Audi factory in Zwickau restarted assembly of the pre-war-models in 1949. These DKW models were renamed to IFA F8 and IFA F9 and were similar to the West German versions. West and East German models were equipped with the traditional and renowned DKW two-stroke engines. The Zwickau plant manufactured the infamous Trabant until 1991, when it came under Volkswagen control—effectively bringing it under the same umbrella as Audi since 1945. === New Auto Union unit === A new West German headquartered Auto Union was launched in Ingolstadt with loans from the Bavarian state government and Marshall Plan aid. The reformed company was launched 3 September 1949 and continued DKW's tradition of producing front-wheel drive vehicles with two-stroke engines. This included production of a small but sturdy 125 cc motorcycle and a DKW delivery van, the DKW F89 L at Ingolstadt. The Ingolstadt site was large, consisting of an extensive complex of formerly military buildings which was suitable for administration as well as vehicle warehousing and distribution, but at this stage there was at Ingolstadt no dedicated plant suitable for mass production of automobiles: for manufacturing the company's first post-war mass-market passenger car plant capacity in Düsseldorf was rented from Rheinmetall-Borsig. It was only ten years later, after the company had attracted an investor, when funds became available for construction of major car plant at the Ingolstadt head office site. In 1958, in response to pressure from Friedrich Flick, then the company's largest single shareholder, Daimler-Benz took an 87% holding in the Auto Union company, and this was increased to a 100% holding in 1959. However, small two-stroke cars were not the focus of Daimler-Benz's interests, and while the early 1960s saw major investment in new Mercedes models and in a state of the art factory for Auto Union's, the company's aging model range at this time did not benefit from the economic boom of the early 1960s to the same extent as competitor manufacturers such as Volkswagen and Opel. The decision to dispose of the Auto Union business was based on its lack of profitability. Ironically, by the time they sold the business, it also included a large new factory and near production-ready modern four-stroke engine, which would enable the Auto Union business, under a new owner, to embark on a period of profitable growth, now producing not Auto Unions or DKWs, but using the "Audi" name, resurrected in 1965 after a 25-year gap. In 1964, Volkswagen acquired a 50% holding in the business, which included the new factory in Ingolstadt, the DKW and Audi brands along with the rights to the new engine design which had been funded by Daimler-Benz, who in return retained the dormant Horch trademark and the Düsseldorf factory which became a Mercedes-Benz van assembly plant. Eighteen months later, Volkswagen bought complete control of Ingolstadt, and by 1966 were using the spare capacity of the Ingolstadt plant to assemble an additional 60,000 Volkswagen Beetles per year. Two-stroke engines became less popular during the 1960s as customers were more attracted to the smoother four-stroke engines. In September 1965, the DKW F102 was fitted with a four-stroke engine and a facelift for the car's front and rear. Volkswagen dumped the DKW brand because of its associations with two-stroke technology, and having classified the model internally as the F103, sold it simply as the "Audi". Later developments of the model were named after their horsepower ratings and sold as the Audi 60, 75, 80, and Super 90, selling until 1972. Initially, Volkswagen was hostile to the idea of Auto Union as a standalone entity producing its own models having acquired the company merely to boost its own production capacity through the Ingolstadt assembly plant – to the point where Volkswagen executives ordered that the Auto Union name and flags bearing the four rings were removed from the factory buildings. Then VW chief Heinz Nordhoff explicitly forbade Auto Union from any further product development. Fearing that the Volkswagen had no long term ambition for the Audi brand, Auto Union engineers under the leadership of Ludwig Kraus developed the first Audi 100 in secret, without Nordhoff's knowledge. When presented with a finished prototype, Nordhoff was so impressed he authorised the car for production, which when launched in 1968, went on to be a huge success. With this, the resurrection of the Audi brand was now complete, this being followed by the first generation Audi 80 in 1972, which would in turn provide a template for VW's new front-wheel-drive water-cooled range which debuted from the mid-1970s onward. In 1969, Auto Union merged with NSU, based in Neckarsulm, near Stuttgart. In the 1950s, NSU had been the world's largest manufacturer of motorcycles, but had moved on to produce small cars like the NSU Prinz, the TT and TTS versions of which are still popular as vintage race cars. NSU then focused on new rotary engines based on the ideas of Felix Wankel. In 1967, the new NSU Ro 80 was a car well ahead of its time in technical details such as aerodynamics, light weight, and safety. However, teething problems with the rotary engines put an end to the independence of NSU. The Neckarsulm plant is now used to produce the larger Audi models A6 and A8. The Neckarsulm factory is also home of the "quattro GmbH" (from November 2016 "Audi Sport GmbH"), a subsidiary responsible for development and production of Audi high-performance models: the R8 and the "RS" model range. === Modern era === The new merged company was incorporated on 1 January 1969 and was known as Audi NSU Auto Union AG, with its headquarters at NSU's Neckarsulm plant, and saw the emergence of Audi as a separate brand for the first time since the pre-war era. Volkswagen introduced the Audi brand to the United States for the 1970 model year. That same year, the mid-sized car that NSU had been working on, the K70, originally intended to slot between the rear-engined Prinz models and the futuristic NSU Ro 80, was instead launched as a Volkswagen. After the launch of the Audi 100 of 1968, the Audi 80/Fox (which formed the basis for the 1973 Volkswagen Passat) followed in 1972 and the Audi 50 (later rebadged as the Volkswagen Polo) in 1974. The Audi 50 was a seminal design because it was the first incarnation of the Golf/Polo concept, one that led to a hugely successful world car. Ultimately, the Audi 80 and 100 (progenitors of the A4 and A6, respectively) became the company's biggest sellers, whilst little investment was made in the fading NSU range; the Prinz models were dropped in 1973 whilst the fatally flawed NSU Ro80 went out of production in 1977, spelling the effective end of the NSU brand. Production of the Audi 100 had been steadily moved from Ingolstadt to Neckarsulm as the 1970s had progressed, any by the appearance of the second generation C2 version in 1976, all production was now at the former NSU plant. Neckarsulm from that point onward would produce Audi's higher end models. The Audi image at this time was a conservative one, and so, a proposal from chassis engineer Jörg Bensinger was accepted to develop the four-wheel drive technology in Volkswagen's Iltis military vehicle for an Audi performance car and rally racing car. The performance car, introduced in 1980, was named the "Audi Quattro", a turbocharged coupé which was also the first German large-scale production vehicle to feature permanent all-wheel drive through a centre differential. Commonly referred to as the "Ur-Quattro" (the "Ur-" prefix is a German augmentative used, in this case, to mean "original" and is also applied to the first generation of Audi's S4 and S6 Sport Saloons, as in "UrS4" and "UrS6"), few of these vehicles were produced (all hand-built by a single team), but the model was a great success in rallying. Prominent wins proved the viability of all-wheel drive racecars, and the Audi name became associated with advances in automotive technology. In 1985, with the Auto Union and NSU brands effectively dead, the company's official name was now shortened to simply Audi AG. At the same time the company's headquarters moved back to Ingolstadt and two new wholly owned subsidiaries; Auto Union GmbH and NSU GmbH, were formed to own and manage the historical trademarks and intellectual property of the original constituent companies (the exception being Horch, which had been retained by Daimler-Benz after the VW takeover), and to operate Audi's heritage operations. In 1986, as the Passat-based Audi 80 was beginning to develop a kind of "grandfather's car" image, the type 89 was introduced. This completely new development sold extremely well. However, its modern and dynamic exterior belied the low performance of its base engine, and its base package was quite spartan (even the passenger-side mirror was an option.) In 1987, Audi put forward a new and very elegant Audi 90, which had a much superior set of standard features. In the early 1990s, sales began to slump for the Audi 80 series, and some basic construction problems started to surface. In the early part of the 21st century, Audi set forth on a German racetrack to claim and maintain several world records, such as top speed endurance. This effort was in-line with the company's heritage from the 1930s racing era Silver Arrows. Through the early 1990s, Audi began to shift its target market upscale to compete against German automakers Mercedes-Benz and BMW. This began with the release of the Audi V8 in 1990. It was essentially a new engine fitted to the Audi 100/200, but with noticeable bodywork differences. Most obvious was the new grille that was now incorporated in the bonnet. By 1991, Audi had the four-cylinder Audi 80, the 5-cylinder Audi 90 and Audi 100, the turbocharged Audi 200 and the Audi V8. There was also a coupe version of the 80/90 with both 4- and 5-cylinder engines. Although the five-cylinder engine was a successful and robust powerplant, it was still a little too different for the target market. With the introduction of an all-new Audi 100 in 1992, Audi introduced a 2.8L V6 engine. This engine was also fitted to a face-lifted Audi 80 (all 80 and 90 models were now badged 80 except for the USA), giving this model a choice of four-, five-, and six-cylinder engines, in Saloon, Coupé and Cabriolet body styles. The five-cylinder was soon dropped as a major engine choice; however, a turbocharged 230 hp (170 kW) version remained. The engine, initially fitted to the 200 quattro 20V of 1991, was a derivative of the engine fitted to the Sport Quattro. It was fitted to the Audi Coupé, and named the S2 and also to the Audi 100 body, and named the S4. These two models were the beginning of the mass-produced S series of performance cars. === Audi 5000 unintended acceleration allegations === Sales in the United States fell after a series of recalls from 1982 to 1987 of Audi 5000 models associated with reported incidents of sudden unintended acceleration linked to six deaths and 700 accidents. At the time, NHTSA was investigating 50 car models from 20 manufacturers for sudden surges of power.A 60 Minutes report aired 23 November 1986, featuring interviews with six people who had sued Audi after reporting unintended acceleration, showing an Audi 5000 ostensibly suffering a problem when the brake pedal was pushed. Subsequent investigation revealed that 60 Minutes had engineered the failure – fitting a canister of compressed air on the passenger-side floor, linked via a hose to a hole drilled into the transmission. Audi contended, prior to findings by outside investigators, that the problems were caused by driver error, specifically pedal misapplication. Subsequently, the National Highway Traffic Safety Administration (NHTSA) concluded that the majority of unintended acceleration cases, including all the ones that prompted the 60 Minutes report, were caused by driver error such as confusion of pedals. CBS did not acknowledge the test results of involved government agencies, but did acknowledge the similar results of another study.In a review study published in 2012, NHTSA summarized its past findings about the Audi unintended acceleration problems: "Once an unintended acceleration had begun, in the Audi 5000, due to a failure in the idle-stabilizer system (producing an initial acceleration of 0.3g), pedal misapplication resulting from panic, confusion, or unfamiliarity with the Audi 5000 contributed to the severity of the incident."This summary is consistent with the conclusions of NHTSA's most technical analysis at the time: "Audi idle-stabilization systems were prone to defects which resulted in excessive idle speeds and brief unanticipated accelerations of up to 0.3g [which is similar in magnitude to an emergency stop in a subway car]. These accelerations could not be the sole cause of [(long-duration) sudden acceleration incidents (SAI)], but might have triggered some SAIs by startling the driver. The defective idle-stabilization system performed a type of electronic throttle control. Significantly: multiple "intermittent malfunctions of the electronic control unit were observed and recorded ... and [were also observed and] reported by Transport Canada."With a series of recall campaigns, Audi made several modifications; the first adjusted the distance between the brake and accelerator pedal on automatic-transmission models. Later repairs, of 250,000 cars dating back to 1978, added a device requiring the driver to press the brake pedal before shifting out of park. A legacy of the Audi 5000 and other reported cases of sudden unintended acceleration are intricate gear stick patterns and brake interlock mechanisms to prevent inadvertent shifting into forward or reverse. It is unclear how the defects in the idle-stabilization system were addressed. Audi's U.S. sales, which had reached 74,061 in 1985, dropped to 12,283 in 1991 and remained level for three years. – with resale values falling dramatically. Audi subsequently offered increased warranty protection and renamed the affected models – with the 5000 becoming the 100 and 200 in 1989 – and reached the same sales levels again only by model year 2000.A 2010 BusinessWeek article – outlining possible parallels between Audi's experience and 2009–2010 Toyota vehicle recalls – noted a class-action lawsuit filed in 1987 by about 7,500 Audi 5000-model owners remains unsettled and is remains contested in Chicago's Cook County after appeals at the Illinois state and U.S. federal levels. === Model introductions === In the mid-to-late 1990s, Audi introduced new technologies including the use of aluminum construction. Produced from 1999 to 2005, the Audi A2 was a futuristic super mini, born from the Al2 concept, with many features that helped regain consumer confidence, like the aluminium space frame, which was a first in production car design. In the A2 Audi further expanded their TDI technology through the use of frugal three-cylinder engines. The A2 was extremely aerodynamic and was designed around a wind tunnel. The Audi A2 was criticised for its high price and was never really a sales success but it planted Audi as a cutting-edge manufacturer. The model, a Mercedes-Benz A-Class competitor, sold relatively well in Europe. However, the A2 was discontinued in 2005 and Audi decided not to develop an immediate replacement. The next major model change came in 1995 when the Audi A4 replaced the Audi 80. The new nomenclature scheme was applied to the Audi 100 to become the Audi A6 (with a minor facelift). This also meant the S4 became the S6 and a new S4 was introduced in the A4 body. The S2 was discontinued. The Audi Cabriolet continued on (based on the Audi 80 platform) until 1999, gaining the engine upgrades along the way. A new A3 hatchback model (sharing the Volkswagen Golf Mk4's platform) was introduced to the range in 1996, and the radical Audi TT coupé and roadster were debuted in 1998 based on the same underpinnings. The engines available throughout the range were now a 1.4 L, 1.6 L and 1.8 L four-cylinder, 1.8 L four-cylinder turbo, 2.6 L and 2.8 L V6, 2.2 L turbo-charged five-cylinder and the 4.2 L V8 engine. The V6s were replaced by new 2.4 L and 2.8 L 30V V6s in 1998, with marked improvement in power, torque and smoothness. Further engines were added along the way, including a 3.7 L V8 and 6.0 L W12 engine for the A8. === Audi AG today === Audi's sales grew strongly in the 2000s, with deliveries to customers increasing from 653,000 in 2000 to 1,003,000 in 2008. The largest sales increases came from Eastern Europe (+19.3%), Africa (+17.2%) and the Middle East (+58.5%). China in particular has become a key market, representing 108,000 out of 705,000 cars delivered in the first three quarters of 2009. One factor for its popularity in China is that Audis have become the car of choice for purchase by the Chinese government for officials, and purchases by the government are responsible for 20% of its sales in China. As of late 2009, Audi's operating profit of €1.17-billion ($1.85-billion) made it the biggest contributor to parent Volkswagen Group's nine-month operating profit of €1.5-billion, while the other marques in Group such as Bentley and SEAT had suffered considerable losses. May 2011 saw record sales for Audi of America with the new Audi A7 and Audi A3 TDI Clean Diesel. In May 2012, Audi reported a 10% increase in its sales—from 408 units to 480 in the last year alone.Audi manufactures vehicles in seven plants around the world, some of which are shared with other VW Group marques although many sub-assemblies such as engines and transmissions are manufactured within other Volkswagen Group plants. Audi's two principal assembly plants are: Ingolstadt, Opened by Auto Union in 1964, (A3, A4, A5, Q5) Neckarsulm, Acquired from NSU in 1969 (A4, A6, A7, A8, R8 & all RS variants)Outside of Germany, Audi produces vehicles at: Aurangabad, India since 2006 Bratislava, Slovakia, shared with Volkswagen, SEAT, Škoda and Porsche (Q7) Brussels, Belgium, acquired from Volkswagen in 2007 (A1) Changchun, China since 1995 Győr, Hungary, (TT and some A3 variants) Jakarta, Indonesia since 2011 Martorell, Spain shared with SEAT and Volkswagen (Q3) San José Chiapa, Mexico (Q5)In September 2012, Audi announced the construction of its first North American manufacturing plant in Puebla, Mexico. This plant is expected to be operative in 2016 and produce the second generation Q5.From 2002 up to 2003, Audi headed the Audi Brand Group, a subdivision of the Volkswagen Group's Automotive Division consisting of Audi, Lamborghini and SEAT, that was focused on sporty values, with the marques' product vehicles and performance being under the higher responsibility of the Audi brand. On January 2014, Audi, along with the Wireless Power Consortium, operated a booth which demonstrated a phone compartment using the Qi open interface standard at the Consumer Electronics Show (CES). In May, most of the Audi dealers in UK falsely claimed that the Audi A7, A8, and R8 were Euro NCAP safety tested, all achieving five out of five stars. In fact none were tested.In 2015, Audi admitted that at least 2.1 million Audi cars had been involved in the Volkswagen emissions testing scandal in which software installed in the cars manipulated emissions data to fool regulators and allow the cars to pollute at higher than government-mandated levels. The A1, A3, A4, A5, A6, TT, Q3 and Q5 models were implicated in the scandal. Audi promised to quickly find a technical solution and upgrade the cars so they can function within emissions regulations. Ulrich Hackenberg, the head of research and development at Audi, was suspended in relation to the scandal. Despite widespread media coverage about the scandal through the month of September, Audi reported that U.S. sales for the month had increased by 16.2%. Audi's parent company Volkswagen announced on 18 June 2018 that Audi chief executive Rupert Stadler had been arrested.In November 2015, the U.S. Environmental Protection Agency implicated the 3-liter diesel engine versions of the 2016 Audi A6 Quattro, A7 Quattro, A8, A8L and the Q5 as further models that had emissions regulation defeat-device software installed. Thus, these models emitted nitrogen oxide at up to nine times the legal limit when the car detected that it was not hooked up to emissions testing equipment.In November 2016, Audi expressed an intention to establish an assembly factory in Pakistan, with the company's local partner acquiring land for a plant in Korangi Creek Industrial Park in Karachi. Approval of the plan would lead to an investment of $30 million in the new plant. == Technology == === Audi AI === Audi AI is a driver assist feature offered by Audi. The company's stated intent is to offer fully autonomous driving at a future time, acknowledging that legal, regulatory and technical hurdles must be overcome to achieve this goal. On June 4, 2017, Audi stated that its new A8 will be fully self-driving for speeds up to 60 km/h using its Audi AI. Contrary to other cars, the driver will not have to do safety checks such as touching the steering wheel every 15 seconds to use this feature. The Audi A8 will therefore be the first production car to reach level 3 autonomous driving, meaning that the driver can safely turn their attention away from driving tasks, e.g. the driver can text or watch a movie. Audi will also be the first manufacturer to use a 3D LIDAR system in addition to cameras and ultrasonic sensors for their AI. === Bodyshells === Audi produces 100% galvanised cars to prevent corrosion, and was the first mass-market vehicle to do so, following introduction of the process by Porsche, c. 1975. Along with other precautionary measures, the full-body zinc coating has proved to be very effective in preventing rust. The body's resulting durability even surpassed Audi's own expectations, causing the manufacturer to extend its original 10-year warranty against corrosion perforation to currently 12 years (except for aluminium bodies which do not rust). === Space frame === Audi introduced a new series of vehicles in the mid-1990s and continues to pursue new technology and high performance. An all-aluminium car was brought forward by Audi, and in 1994 the Audi A8 was launched, which introduced aluminium space frame technology (called Audi Space Frame or ASF) which saves weight and improves torsion rigidity compared to a conventional steel frame. Prior to that effort, Audi used examples of the Type 44 chassis fabricated out of aluminium as test-beds for the technique. The disadvantage of the aluminium frame is that it is very expensive to repair and requires a specialized aluminium bodyshop. The weight reduction is somewhat offset by the quattro four-wheel drive system which is standard in most markets. Nonetheless, the A8 is usually the lightest all-wheel drive car in the full-size luxury segment, also having best-in-class fuel economy. The Audi A2, Audi TT and Audi R8 also use Audi Space Frame designs. === Drivetrains === ==== Layout ==== For most of its lineup (excluding the A3, A1, and TT models), Audi has not adopted the transverse engine layout which is typically found in economy cars (such as Peugeot and Citroën), since that would limit the type and power of engines that can be installed. To be able to mount powerful engines (such as a V8 engine in the Audi S4 and Audi RS4, as well as the W12 engine in the Audi A8L W12), Audi has usually engineered its more expensive cars with a longitudinally front-mounted engine, in an "overhung" position, over the front wheels in front of the axle line - this layout dates back to the DKW and Auto Union saloons from the 1950s. But while this allows for the easy adoption of all-wheel drive, it goes against the ideal 50:50 weight distribution. In all its post Volkswagen-era models, Audi has firmly refused to adopt the traditional rear-wheel drive layout favored by its two archrivals Mercedes-Benz and BMW, favoring either front-wheel drive or all-wheel drive. The majority of Audi's lineup in the United States features all-wheel drive standard on most of its expensive vehicles (only the entry-level trims of the A4 and A6 are available with front-wheel drive), in contrast to Mercedes-Benz and BMW whose lineup treats all-wheel drive as an option. BMW did not offer all-wheel drive on its V8-powered cars (as opposed to crossover SUVs) until the 2010 BMW 7 Series and 2011 BMW 5 Series, while the Audi A8 has had all-wheel drive available/standard since the 1990s. Regarding high-performance variants, Audi S and RS models have always had all-wheel drive, unlike their direct rivals from BMW M and Mercedes-AMG whose cars are rear-wheel drive only (although their performance crossover SUVs are all-wheel drive). Audi has recently applied the quattro badge to models such as the A3 and TT which do not use the Torsen-based system as in prior years with a mechanical center differential, but with the Haldex Traction electro-mechanical clutch AWD system. ==== Engines ==== Prior to the introduction of the Audi 80 and Audi 50 in 1972 and 1974, respectively, Audi had led the development of the EA111 and EA827 inline-four engine families. These new power units underpinned the water-cooled revival of parent company Volkswagen (in the Polo, Golf, Passat and Scirocco), whilst the many derivatives and descendants of these two basic engine designs have appeared in every generation of VW Group vehicles right up to the present day. In the 1980s, Audi, along with Volvo, was the champion of the inline-five cylinder, 2.1/2.2 L engine as a longer-lasting alternative to more traditional six-cylinder engines. This engine was used not only in production cars but also in their race cars. The 2.1 L inline five-cylinder engine was used as a base for the rally cars in the 1980s, providing well over 400 horsepower (300 kilowatts) after modification. Before 1990, there were engines produced with a displacement between 2.0 L and 2.3 L. This range of engine capacity allowed for both fuel economy and power. For the ultra-luxury version of its Audi A8 fullsize luxury flagship sedan, the Audi A8L W12, Audi uses the Volkswagen Group W12 engine instead of the conventional V12 engine favored by rivals Mercedes-Benz and BMW. The W12 engine configuration (also known as a "WR12") is created by forming two imaginary narrow-angle 15° VR6 engines at an angle of 72°, and the narrow angle of each set of cylinders allows just two overhead camshafts to drive each pair of banks, so just four are needed in total. The advantage of the W12 engine is its compact packaging, allowing Audi to build a 12-cylinder sedan with all-wheel drive, whereas a conventional V12 engine could have only a rear-wheel drive configuration as it would have no space in the engine bay for a differential and other components required to power the front wheels. In fact, the 6.0 L W12 in the Audi A8L W12 is smaller in overall dimensions than the 4.2 L V8 that powers the Audi A8 4.2 variants. The 2011 Audi A8 debuted a revised 6.3-litre version of the W12 (WR12) engine with 500 PS (370 kW; 490 hp). ==== Fuel Stratified Injection ==== New models of the A3, A4, A6 and A8 have been introduced, with the ageing 1.8-litre engine now having been replaced by new Fuel Stratified Injection (FSI) engines. Nearly every petroleum burning model in the range now incorporates this fuel-saving technology. ==== Direct-Shift Gearbox ==== In 2003 Volkswagen introduced the Direct-Shift Gearbox (DSG), a type of dual clutch transmission. It is an automated semi-automatic transmission, drivable like a conventional automatic transmission. Based on the gearbox found in the Group B S1, the system includes dual electrohydraulically controlled clutches instead of a torque converter. This is implemented in some VW Golfs, Audi A3, Audi A4 and TT models where DSG is called S-tronic. === LED daytime running lights === Beginning in 2005, Audi has implemented white LED technology as daytime running lights (DRL) in their products. The distinctive shape of the DRLs has become a trademark of sorts. LEDs were first introduced on the Audi A8 W12, the world's first production car to have LED DRLs, and have since spread throughout the entire model range. The LEDs are present on some Audi billboards. Since 2010, Audi has also offered the LED technology in low- and high-beam headlights. === Multi Media Interface === Starting with the 2003 Audi A8, Audi has used a centralised control interface for its on-board infotainment systems, called Multi Media Interface (MMI). It is essentially a rotating control knob and 'segment' buttons – designed to control all in-car entertainment devices (radio, CD changer, iPod, TV tuner), satellite navigation, heating and ventilation, and other car controls with a screen. The availability of MMI has gradually filtered down the Audi lineup, and following its introduction on the third generation A3 in 2011, MMI is now available across the entire range. It has been generally well received, as it requires less menu-surfing with its segment buttons around a central knob, along with 'main function' direct access buttons – with shortcuts to the radio or phone functions. The colour screen is mounted on the upright dashboard, and on the A4 (new), A5, A6, A8, and Q7, the controls are mounted horizontally. === Synthetic Diesel === Audi has assisted with technology to produce synthetic diesel from water and carbon dioxide. === Logistics === Audi uses scanning gloves for parts registration during assembly, and automatic robots to transfer cars from factory to rail cars. == Models == === Current model range === The following tables list Audi production vehicles that are sold as of 2014: === S and RS models === === Electric vehicles === Audi is planning an alliance with the Japanese electronics giant Sanyo to develop a pilot hybrid electric project for the Volkswagen Group. The alliance could result in Sanyo batteries and other electronic components being used in future models of the Volkswagen Group. Concept electric vehicles unveiled to date include the Audi A1 Sportback Concept, Audi A4 TDI Concept E, and the fully electric Audi e-tron Concept Supercar. == Production figures == Data from 1998 to 2010. Figures for different body types/versions of models have been merged to create overall figures for each model. == Motorsport == Audi has competed in various forms of motorsports. Audi's tradition in motorsport began with their former company Auto Union in the 1930s. In the 1990s, Audi found success in the Touring and Super Touring categories of motor racing after success in circuit racing in North America. === Rallying === In 1980, Audi released the Quattro, a four-wheel drive (4WD) turbocharged car that went on to win rallies and races worldwide. It is considered one of the most significant rally cars of all time, because it was one of the first to take advantage of the then-recently changed rules which allowed the use of four-wheel drive in competition racing. Many critics doubted the viability of four-wheel drive racers, thinking them to be too heavy and complex, yet the Quattro was to become a successful car. Leading its first rally it went off the road, however the rally world had been served notice 4WD was the future. The Quattro went on to achieve much success in the World Rally Championship. It won the 1983 (Hannu Mikkola) and the 1984 (Stig Blomqvist) drivers' titles, and brought Audi the manufacturers' title in 1982 and 1984. In 1984, Audi launched the short-wheelbase Sport Quattro which dominated rally races in Monte Carlo and Sweden, with Audi taking all podium places, but succumbed to problems further into WRC contention. In 1985, after another season mired in mediocre finishes, Walter Röhrl finished the season in his Sport Quattro S1, and helped place Audi second in the manufacturers' points. Audi also received rally honours in the Hong Kong to Beijing rally in that same year. Michèle Mouton, the only female driver to win a round of the World Rally Championship and a driver for Audi, took the Sport Quattro S1, now simply called the "S1", and raced in the Pikes Peak International Hill Climb. The 1,439-metre (4,721 ft) climb race pits a driver and car to drive to the summit of the 4,302-metre (14,114 ft) Pikes Peak mountain in Colorado, and in 1985, Michèle Mouton set a new record of 11:25.39, and being the first woman to set a Pikes Peak record. In 1986, Audi formally left international rally racing following an accident in Portugal involving driver Joaquim Santos in his Ford RS200. Santos swerved to avoid hitting spectators in the road, and left the track into the crowd of spectators on the side, killing three and injuring 30. Bobby Unser used an Audi in that same year to claim a new record for the Pikes Peak Hill Climb at 11:09.22. In 1987, Walter Röhrl claimed the title for Audi setting a new Pikes Peak International Hill Climb record of 10:47.85 in his Audi S1, which he had retired from the WRC two years earlier. The Audi S1 employed Audi's time-tested inline-five-cylinder turbocharged engine, with the final version generating 441 kW (600 PS; 591 bhp). The engine was mated to a six-speed gearbox and ran on Audi's famous four-wheel drive system. All of Audi's top drivers drove this car; Hannu Mikkola, Stig Blomqvist, Walter Röhrl and Michèle Mouton. This Audi S1 started the range of Audi 'S' cars, which now represents an increased level of sports-performance equipment within the mainstream Audi model range. === In the United States === As Audi moved away from rallying and into circuit racing, they chose to move first into America with the Trans-Am in 1988. In 1989, Audi moved to International Motor Sports Association (IMSA) GTO with the Audi 90, however as they avoided the two major endurance events (Daytona and Sebring) despite winning on a regular basis, they would lose out on the title. === Touring cars === In 1990, having completed their objective to market cars in North America, Audi returned to Europe, turning first to the Deutsche Tourenwagen Meisterschaft (DTM) series with the Audi V8, and then in 1993, being unwilling to build cars for the new formula, they turned their attention to the fast-growing Super Touring series, which are a series of national championships. Audi first entered in the French Supertourisme and Italian Superturismo. In the following year, Audi would switch to the German Super Tourenwagen Cup (known as STW), and then to British Touring Car Championship (BTCC) the year after that. The Fédération Internationale de l'Automobile (FIA), having difficulty regulating the quattro four-wheel drive system, and the impact it had on the competitors, would eventually ban all four-wheel drive cars from competing in 1998, but by then, Audi switched all their works efforts to sports car racing. By 2000, Audi would still compete in the US with their RS4 for the SCCA Speed World GT Challenge, through dealer/team Champion Racing competing against Corvettes, Vipers, and smaller BMWs (where it is one of the few series to permit 4WD cars). In 2003, Champion Racing entered an RS6. Once again, the quattro four-wheel drive was superior, and Champion Audi won the championship. They returned in 2004 to defend their title, but a newcomer, Cadillac with the new Omega Chassis CTS-V, gave them a run for their money. After four victories in a row, the Audis were sanctioned with several negative changes that deeply affected the car's performance. Namely, added ballast weights, and Champion Audi deciding to go with different tyres, and reducing the boost pressure of the turbocharger. In 2004, after years of competing with the TT-R in the revitalised DTM series, with privateer team Abt Racing/Christian Abt taking the 2002 title with Laurent Aïello, Audi returned as a full factory effort to touring car racing by entering two factory supported Joest Racing A4 DTM cars. === 24 Hours of Le Mans === Audi began racing prototype sportscars in 1999, debuting at the Le Mans 24 hour. Two car concepts were developed and raced in their first season - the Audi R8R (open-cockpit 'roadster' prototype) and the Audi R8C (closed-cockpit 'coupé' GT-prototype). The R8R scored a credible podium on its racing debut at Le Mans and was the concept which Audi continued to develop into the 2000 season due to favourable rules for open-cockpit prototypes. However, most of the competitors (such as BMW, Toyota, Mercedes and Nissan) retired at the end of 1999. The factory-supported Joest Racing team won at Le Mans three times in a row with the Audi R8 (2000–2002), as well as winning every race in the American Le Mans Series in its first year. Audi also sold the car to customer teams such as Champion Racing. In 2003, two Bentley Speed 8s, with engines designed by Audi, and driven by Joest drivers loaned to the fellow Volkswagen Group company, competed in the GTP class, and finished the race in the top two positions, while the Champion Racing R8 finished third overall, and first in the LMP900 class. Audi returned to the winner's podium at the 2004 race, with the top three finishers all driving R8s: Audi Sport Japan Team Goh finished first, Audi Sport UK Veloqx second, and Champion Racing third. At the 2005 24 Hours of Le Mans, Champion Racing entered two R8s, along with an R8 from the Audi PlayStation Team Oreca. The R8s (which were built to old LMP900 regulations) received a narrower air inlet restrictor, reducing power, and an additional 50 kg (110 lb) of weight compared to the newer LMP1 chassis. On average, the R8s were about 2–3 seconds off pace compared to the Pescarolo–Judd. But with a team of excellent drivers and experience, both Champion R8s were able to take first and third, while the Oreca team took fourth. The Champion team was also the first American team to win Le Mans since the Gulf Ford GTs in 1967. This also ends the long era of the R8; however, its replacement for 2006, called the Audi R10 TDI, was unveiled on 13 December 2005. The R10 TDI employed many new and innovative features, the most notable being the twin-turbocharged direct injection diesel engine. It was first raced in the 2006 12 Hours of Sebring as a race-test in preparation for the 2006 24 Hours of Le Mans, which it later went on to win. Audi has been on the forefront of sports car racing, claiming a historic win in the first diesel sports car at 12 Hours of Sebring (the car was developed with a Diesel engine due to ACO regulations that favor diesel engines). As well as winning the 24 Hours of Le Mans in 2006 making history, the R10 TDI has also shown its capabilities by beating the Peugeot 908 HDi FAP in 2007, and beating Peugeot again in 2008, (however Peugeot won the 24h in 2009) and, in a podium clean-sweep by proving its reliability throughout the race (compared to all four 908 entries retired before the end of the race) while breaking a new distance record (set way back by the Porsche 917K of Martini Racing in 1971), in 2010 with the R15 TDI Plus.Audi's sports car racing success would continue with the Audi R18's victory at the 2011 24 Hours of Le Mans. Audi Sport Team Joest's Benoît Tréluyer earned Audi their first pole position in five years while the team's sister car locked out the front row. Early accidents eliminated two of Audi's three entries, but the sole remaining Audi R18 TDI of Tréluyer, Marcel Fässler, and André Lotterer held off the trio of Peugeot 908s to claim victory by a margin of 13.8 seconds. ==== Results ==== === American Le Mans Series === Audi entered a factory racing team run by Joest Racing into the American Le Mans Series under the Audi Sport North America name in 2000. This was a successful operation with the team winning on its debut in the series at the 2000 12 Hours of Sebring. Factory backed Audi R8s were the dominant car in ALMS taking 25 victories between 2000 and the end of the 2002 season. In 2003 Audi sold customer cars to Champion Racing as well as continuing to race the factory Audi Sport North America team. Champion Racing won many races as a private team running Audi R8s and eventually replaced Team Joest as the Audi Sport North America between 2006 and 2008. Since 2009 Audi has not taken part in full American Le Mans Series Championships, but has competed in the series opening races at Sebring, using the 12-hour race as a test for Le Mans, and also as part of the 2012 FIA World Endurance Championship season calendar. ==== Results ==== === European Le Mans Series === Audi participated in the 2003 1000km of Le Mans which was a one-off sports car race in preparation for the 2004 European Le Mans Series. The factory team Audi Sport UK won races and the championship in the 2004 season but Audi was unable to match their sweeping success of Audi Sport North America in the American Le Mans Series, partly due to the arrival of a factory competitor in LMP1, Peugeot. The French manufacturer's 908 HDi FAP became the car to beat in the series from 2008 onwards with 20 LMP wins. However, Audi were able to secure the championship in 2008 even though Peugeot scored more race victories in the season. ==== Results ==== === World Endurance Championship === ==== 2012 ==== In 2012, the FIA sanctioned a World Endurance Championship which would be organised by the ACO as a continuation of the ILMC. Audi competed won the first WEC race at Sebring and followed this up with a further three successive wins, including the 2012 24 Hours of Le Mans. Audi scored a final 5th victory in the 2012 WEC in Bahrain and were able to win the inaugural WEC Manufacturers' Championship. ==== 2013 ==== As defending champions, Audi once again entered the Audi R18 e-tron quattro chassis into the 2013 WEC and the team won the first five consecutive races, including the 2013 24 Hours of Le Mans. The victory at Round 5, Circuit of the Americas, was of particular significance as it marked the 100th win for Audi in Le Mans prototypes. Audi secured their second consecutive WEC Manufacturers' Championship at Round 6 after taking second place and half points in the red-flagged Fuji race. ==== 2014 ==== For the 2014 season Audi entered a redesigned and upgraded R18 e-tron quattro which featured a 2 MJ energy recovery system. As defending champions, Audi would once again face a challenge in LMP1 from Toyota, and additionally from Porsche who returned to endurance racing after a 16-year absence. The season opening 6hrs of Silverstone was a disaster for Audi who saw both cars retire from the race, marking the first time that an Audi car has failed to score a podium in a World Endurance Championship race. ==== Results ==== === Formula E === Audi provide factory support to Abt Sportsline in the FIA Formula E Championship, The team competed under the title of Audi Sport Abt Formula E Team in the inaugural 2014-15 Formula E season. On 13 February 2014 the team announced its driver line up as Daniel Abt and World Endurance Championship driver Lucas di Grassi. === Formula One === Audi has been linked to Formula One in recent years but has always resisted due to the company's opinion that it is not relevant to road cars, but hybrid power unit technology has been adopted into the sport, swaying the company's view and encouraging research into the program by former Ferrari team principal Stefano Domenicali. == Marketing == === Branding === The Audi emblem is four overlapping rings that represent the four marques of Auto Union. The Audi emblem symbolises the amalgamation of Audi with DKW, Horch and Wanderer: the first ring from the left represents Audi, the second represents DKW, third is Horch, and the fourth and last ring Wanderer. The design is popularly believed to have been the idea of Klaus von Oertzen, the director of sales at Wanderer - when Berlin was chosen as the host city for the 1936 Summer Olympics and that a form of the Olympic logo symbolized the newly established Auto Union's desire to succeed. Somewhat ironically, the International Olympic Committee later sued Audi in the International Trademark Court in 1995, where they lost.The original "Audi" script, with the distinctive slanted tails on the "A" and "d" was created for the historic Audi company in 1920 by the famous graphic designer Lucian Bernhard, and was resurrected when Volkswagen revived the brand in 1965. Following the demise of NSU in 1977, less prominence was given to the four rings, in preference to the "Audi" script encased within a black (later red) ellipse, and was commonly displayed next to the Volkswagen roundel when the two brands shared a dealer network under the V.A.G banner. The ellipse (known as the Audi Oval) was phased out after 1994, when Audi formed its own independent dealer network, and prominence was given back to the four rings - at the same time Audi Sans (a derivative of Univers) was adopted as the font for all marketing materials, corporate communications and was also used in the vehicles themselves. As part of Audi's centennial celebration in 2009, the company updated the logo, changing the font to left-aligned Audi Type, and altering the shading for the overlapping rings. The revised logo was designed by Rayan Abdullah.Audi developed a Corporate Sound concept, with Audi Sound Studio designed for producing the Corporate Sound. The Corporate Sound project began with sound agency Klangerfinder GmbH & Co KG and s12 GmbH. Audio samples were created in Klangerfinder's sound studio in Stuttgart, becoming part of Audi Sound Studio collection. Other Audi Sound Studio components include The Brand Music Pool, The Brand Voice. Audi also developed Sound Branding Toolkit including certain instruments, sound themes, rhythm and car sounds which all are supposed to reflect the AUDI sound character.Audi started using a beating heart sound trademark beginning in 1996. An updated heartbeat sound logo, developed by agencies KLANGERFINDER GmbH & Co KG of Stuttgart and S12 GmbH of Munich, was first used in 2010 in an Audi A8 commercial with the slogan "The Art of Progress." ==== Slogans ==== Audi's corporate tagline is Vorsprung durch Technik, meaning "Progress through Technology". The German-language tagline is used in many European countries, including the United Kingdom, and in other markets, such as Latin America, Oceania and parts of Asia including Japan. A few years ago, the North American tagline was "Innovation through technology", but in Canada the German tagline Vorsprung durch Technik was used in advertising. Since 2007, Audi has used the slogan "Truth in Engineering" in the U.S. However, since the Audi emissions testing scandal came to light in September 2015, this slogan was lambasted for being discordant with reality. In fact, just hours after disgraced Volkswagen CEO Martin Winterkorn admitted to cheating on emissions data, an advertisement during the 2015 Primetime Emmy Awards promoted Audi's latest advances in low emissions technology with Kermit the Frog stating, "It's not that easy being green."It was first used in English-language advertising after Sir John Hegarty of the Bartle Bogle Hegarty advertising agency visited the Audi factory in 1982. In the original British television commercials, the phrase was voiced by Geoffrey Palmer. After its repeated use in advertising campaigns, the phrase found its way into popular culture, including the British comedy Only Fools and Horses, the U2 song "Zooropa" and the Blur song "Parklife". Similar-sounding phrases have also been used, including as the punchline for a joke in the movie Lock, Stock, and Two Smoking Barrels and in the British TV series Peep Show. ==== Typography ==== Audi Sans (based on Univers Extended) was originally created in 1997 by Ole Schäfer for MetaDesign. MetaDesign was later commissioned for a new corporate typeface called Audi Type, designed by Paul van der Laan and Pieter van Rosmalen of Bold Monday. The font began to appear in Audi's 2009 products and marketing materials. === Sponsorships === Audi is a strong partner of different kinds of sports. In football, long partnerships exist between Audi and domestic clubs including Bayern Munich, Hamburger SV, 1. FC Nürnberg, Hertha BSC, and Borussia Mönchengladbach and international clubs including Chelsea, Real Madrid, FC Barcelona, A.C. Milan, AFC Ajax and Perspolis. Audi also sponsors winter sports: The Audi FIS Alpine Ski World Cup is named after the company. Additionally, Audi supports the German Ski Association (DSV) as well as the alpine skiing national teams of Switzerland, Sweden, Finland, France, Liechtenstein, Italy, Austria and the U.S. For almost two decades, Audi fosters golf sport: for example with the Audi quattro Cup and the HypoVereinsbank Ladies German Open presented by Audi. In sailing, Audi is engaged in the Medcup regatta and supports the team Luna Rossa during the Louis Vuitton Pacific Series and also is the primary sponsor of the Melges 20 sailboat. Further, Audi sponsors the regional teams ERC Ingolstadt (hockey) and FC Ingolstadt 04 (soccer). In 2009, the year of Audi's 100th anniversary, the company organized the Audi Cup for the first time. Audi also sponsor the New York Yankees as well. In October 2010 they agreed to a three sponsorship year-deal with Everton. Audi also sponsors the England Polo Team and holds the Audi Polo Awards. === Multitronic campaign === In 2001, Audi promoted the new multitronic continuously variable transmission with television commercials throughout Europe, featuring an impersonator of musician and actor Elvis Presley. A prototypical dashboard figure – later named "Wackel-Elvis" ("Wobble Elvis" or "Wobbly Elvis") – appeared in the commercials to demonstrate the smooth ride in an Audi equipped with the multitronic transmission. The dashboard figure was originally intended for use in the commercials only, but after they aired the demand for Wackel-Elvis fans grew among fans and the figure was mass-produced in China and marketed by Audi in their factory outlet store. === Audi TDI === As part of Audi's attempt to promote its Diesel technology in 2009, the company began Audi Mileage Marathon. The driving tour featured a fleet of 23 Audi TDI vehicles from 4 models (Audi Q7 3.0 TDI, Audi Q5 3.0 TDI, Audi A4 3.0 TDI, Audi A3 Sportback 2.0 TDI with S tronic transmission) travelling across the American continent from New York to Los Angeles, passing major cities like Chicago, Dallas and Las Vegas during the 13 daily stages, as well as natural wonders including the Rocky Mountains, Death Valley and the Grand Canyon. === Audi e-tron === The next phase of technology Audi is developing is the e-tron electric drive powertrain system. They have shown several concept cars as of March 2010, each with different levels of size and performance. The original e-tron concept shown at the 2009 Frankfurt motor show is based on the platform of the R8 and has been scheduled for limited production. Power is provided by electric motors at all four wheels. The second concept was shown at the 2010 Detroit Motor Show. Power is provided by two electric motors at the rear axle. This concept is also considered to be the direction for a future mid-engined gas-powered 2-seat performance coupe. The Audi A1 e-tron concept, based on the Audi A1 production model, is a hybrid vehicle with a range extending Wankel rotary engine to provide power after the initial charge of the battery is depleted. It is the only concept of the three to have range extending capability. The car is powered through the front wheels, always using electric power. It is all set to be displayed at the Auto Expo 2012 in New Delhi, India, from 5 January. Powered by a 1.4 litre engine, and can cover a distance up to 54 km s on a single charge. The e-tron was also shown in the 2013 blockbuster film Iron Man 3 and was driven by Tony Stark (Iron Man). === In video games === In PlayStation Home, the PlayStation 3's online community-based service, Audi has supported Home by releasing a dedicated Home space in the European version of Home. Audi is the first carmaker to develop a space for Home. On 17 December 2009, Audi released the Audi Space as two spaces; the Audi Home Terminal and the Audi Vertical Run. The Audi Home Terminal features an Audi TV channel delivering video content, an Internet Browser feature, and a view of a city. The Audi Vertical Run is where users can access the mini-game Vertical Run, a futuristic mini-game featuring Audi's e-tron concept. Players collect energy and race for the highest possible speeds and the fastest players earn a place in the Audi apartments located in a large tower in the centre of the Audi Space. In both the Home Terminal and Vertical Run spaces, there are teleports where users can teleport back and forth between the two spaces. Audi has stated that additional content will be added in 2010. == See also == Wanderer (car) DKW Horch == Notes == == References == Oswald, Werner (2001).

### Instruction: retrieve labels for this: Alexander Graham Bell (March 3, 1847 – August 2, 1922) was a Scottish-born scientist, inventor, engineer, and innovator who is credited with inventing and patenting the first practical telephone. He also founded the American Telephone and Telegraph Company (AT&T) in 1885.Bell's father, grandfather, and brother had all been associated with work on elocution and speech and both his mother and wife were deaf, profoundly influencing Bell's life's work. His research on hearing and speech further led him to experiment with hearing devices which eventually culminated in Bell being awarded the first U.S. patent for the telephone in 1876. Bell considered his invention an intrusion on his real work as a scientist and refused to have a telephone in his study.Many other inventions marked Bell's later life, including groundbreaking work in optical telecommunications, hydrofoils, and aeronautics. Although Bell was not one of the 33 founders of the National Geographic Society, he had a strong influence on the magazine while serving as the second president from January 7, 1898, until 1903. == Early life == Alexander Bell was born in Edinburgh, Scotland, on March 3, 1847. The family home was at 16 South Charlotte Street, and has a stone inscription marking it as Alexander Graham Bell's birthplace. He had two brothers: Melville James Bell (1845–70) and Edward Charles Bell (1848–67), both of whom would die of tuberculosis. His father was Professor Alexander Melville Bell, a phonetician, and his mother was Eliza Grace (née Symonds). Born as just "Alexander Bell", at age 10, he made a plea to his father to have a middle name like his two brothers. For his 11th birthday, his father acquiesced and allowed him to adopt the name "Graham", chosen out of respect for Alexander Graham, a Canadian being treated by his father who had become a family friend. To close relatives and friends he remained "Aleck". === First invention === As a child, young Bell displayed a natural curiosity about his world, resulting in gathering botanical specimens as well as experimenting even at an early age. His best friend was Ben Herdman, a neighbour whose family operated a flour mill, the scene of many forays. Young Bell asked what needed to be done at the mill. He was told wheat had to be dehusked through a laborious process and at the age of 12, Bell built a homemade device that combined rotating paddles with sets of nail brushes, creating a simple dehusking machine that was put into operation and used steadily for a number of years. In return, Ben's father John Herdman gave both boys the run of a small workshop in which to "invent".From his early years, Bell showed a sensitive nature and a talent for art, poetry, and music that was encouraged by his mother. With no formal training, he mastered the piano and became the family's pianist. Despite being normally quiet and introspective, he revelled in mimicry and "voice tricks" akin to ventriloquism that continually entertained family guests during their occasional visits. Bell was also deeply affected by his mother's gradual deafness (she began to lose her hearing when he was 12), and learned a manual finger language so he could sit at her side and tap out silently the conversations swirling around the family parlour. He also developed a technique of speaking in clear, modulated tones directly into his mother's forehead wherein she would hear him with reasonable clarity. Bell's preoccupation with his mother's deafness led him to study acoustics. His family was long associated with the teaching of elocution: his grandfather, Alexander Bell, in London, his uncle in Dublin, and his father, in Edinburgh, were all elocutionists. His father published a variety of works on the subject, several of which are still well known, especially his The Standard Elocutionist (1860), which appeared in Edinburgh in 1868. The Standard Elocutionist appeared in 168 British editions and sold over a quarter of a million copies in the United States alone. In this treatise, his father explains his methods of how to instruct deaf-mutes (as they were then known) to articulate words and read other people's lip movements to decipher meaning. Bell's father taught him and his brothers not only to write Visible Speech but to identify any symbol and its accompanying sound. Bell became so proficient that he became a part of his father's public demonstrations and astounded audiences with his abilities. He could decipher Visible Speech representing virtually every language, including Latin, Scottish Gaelic, and even Sanskrit, accurately reciting written tracts without any prior knowledge of their pronunciation. === Education === As a young child, Bell, like his brothers, received his early schooling at home from his father. At an early age, he was enrolled at the Royal High School, Edinburgh, Scotland, which he left at the age of 15, having completed only the first four forms. His school record was undistinguished, marked by absenteeism and lacklustre grades. His main interest remained in the sciences, especially biology while he treated other school subjects with indifference, to the dismay of his demanding father. Upon leaving school, Bell travelled to London to live with his grandfather, Alexander Bell. During the year he spent with his grandfather, a love of learning was born, with long hours spent in serious discussion and study. The elder Bell took great efforts to have his young pupil learn to speak clearly and with conviction, the attributes that his pupil would need to become a teacher himself. At the age of 16, Bell secured a position as a "pupil-teacher" of elocution and music, in Weston House Academy at Elgin, Moray, Scotland. Although he was enrolled as a student in Latin and Greek, he instructed classes himself in return for board and £10 per session. The following year, he attended the University of Edinburgh; joining his older brother Melville who had enrolled there the previous year. In 1868, not long before he departed for Canada with his family, Bell completed his matriculation exams and was accepted for admission to University College London. === First experiments with sound === His father encouraged Bell's interest in speech and, in 1863, took his sons to see a unique automaton developed by Sir Charles Wheatstone based on the earlier work of Baron Wolfgang von Kempelen. The rudimentary "mechanical man" simulated a human voice. Bell was fascinated by the machine and after he obtained a copy of von Kempelen's book, published in German, and had laboriously translated it, he and his older brother Melville built their own automaton head. Their father, highly interested in their project, offered to pay for any supplies and spurred the boys on with the enticement of a "big prize" if they were successful. While his brother constructed the throat and larynx, Bell tackled the more difficult task of recreating a realistic skull. His efforts resulted in a remarkably lifelike head that could "speak", albeit only a few words. The boys would carefully adjust the "lips" and when a bellows forced air through the windpipe, a very recognizable "Mama" ensued, to the delight of neighbours who came to see the Bell invention.Intrigued by the results of the automaton, Bell continued to experiment with a live subject, the family's Skye Terrier, "Trouve". After he taught it to growl continuously, Bell would reach into its mouth and manipulate the dog's lips and vocal cords to produce a crude-sounding "Ow ah oo ga ma ma". With little convincing, visitors believed his dog could articulate "How are you, grandma?" Indicative of his playful nature, his experiments convinced onlookers that they saw a "talking dog". These initial forays into experimentation with sound led Bell to undertake his first serious work on the transmission of sound, using tuning forks to explore resonance. At age 19, Bell wrote a report on his work and sent it to philologist Alexander Ellis, a colleague of his father (who would later be portrayed as Professor Henry Higgins in Pygmalion). Ellis immediately wrote back indicating that the experiments were similar to existing work in Germany, and also lent Bell a copy of Hermann von Helmholtz's work, The Sensations of Tone as a Physiological Basis for the Theory of Music.Dismayed to find that groundbreaking work had already been undertaken by Helmholtz who had conveyed vowel sounds by means of a similar tuning fork "contraption", Bell pored over the German scientist's book. Working from his own erroneous mistranslation of a French edition, Bell fortuitously then made a deduction that would be the underpinning of all his future work on transmitting sound, reporting: "Without knowing much about the subject, it seemed to me that if vowel sounds could be produced by electrical means, so could consonants, so could articulate speech." He also later remarked: "I thought that Helmholtz had done it ... and that my failure was due only to my ignorance of electricity. It was a valuable blunder ... If I had been able to read German in those days, I might never have commenced my experiments!" === Family tragedy === In 1865, when the Bell family moved to London, Bell returned to Weston House as an assistant master and, in his spare hours, continued experiments on sound using a minimum of laboratory equipment. Bell concentrated on experimenting with electricity to convey sound and later installed a telegraph wire from his room in Somerset College to that of a friend. Throughout late 1867, his health faltered mainly through exhaustion. His younger brother, Edward "Ted," was similarly bed-ridden, suffering from tuberculosis. While Bell recovered (by then referring to himself in correspondence as "A. G. Bell") and served the next year as an instructor at Somerset College, Bath, England, his brother's condition deteriorated. Edward would never recover. Upon his brother's death, Bell returned home in 1867. His older brother Melville had married and moved out. With aspirations to obtain a degree at University College London, Bell considered his next years as preparation for the degree examinations, devoting his spare time at his family's residence to studying. Helping his father in Visible Speech demonstrations and lectures brought Bell to Susanna E. Hull's private school for the deaf in South Kensington, London. His first two pupils were deaf-mute girls who made remarkable progress under his tutelage. While his older brother seemed to achieve success on many fronts including opening his own elocution school, applying for a patent on an invention, and starting a family, Bell continued as a teacher. However, in May 1870, Melville died from complications due to tuberculosis, causing a family crisis. His father had also suffered a debilitating illness earlier in life and had been restored to health by a convalescence in Newfoundland. Bell's parents embarked upon a long-planned move when they realized that their remaining son was also sickly. Acting decisively, Alexander Melville Bell asked Bell to arrange for the sale of all the family property, conclude all of his brother's affairs (Bell took over his last student, curing a pronounced lisp), and join his father and mother in setting out for the "New World". Reluctantly, Bell also had to conclude a relationship with Marie Eccleston, who, as he had surmised, was not prepared to leave England with him. == Canada == In 1870, aged 23, Bell, together with Bell's brother's widow, Caroline Margaret Ottaway, and his parents travelled on the SS Nestorian to Canada. After landing at Quebec City, the Bells transferred to another steamer to Montreal and then boarded a train to Paris, Ontario, to stay with the Reverend Thomas Henderson, a family friend. After a brief stay with the Hendersons, the Bell family purchased a farm of 10.5 acres (42,000 m2) at Tutelo Heights (now called Tutela Heights), near Brantford, Ontario. The property consisted of an orchard, large farmhouse, stable, pigsty, hen-house, and a carriage house, which bordered the Grand River.At the homestead, Bell set up his own workshop in the converted carriage house near to what he called his "dreaming place", a large hollow nestled in trees at the back of the property above the river. Despite his frail condition upon arriving in Canada, Bell found the climate and environs to his liking, and rapidly improved. He continued his interest in the study of the human voice and when he discovered the Six Nations Reserve across the river at Onondaga, he learned the Mohawk language and translated its unwritten vocabulary into Visible Speech symbols. For his work, Bell was awarded the title of Honorary Chief and participated in a ceremony where he donned a Mohawk headdress and danced traditional dances.After setting up his workshop, Bell continued experiments based on Helmholtz's work with electricity and sound. He also modified a melodeon (a type of pump organ) so that it could transmit its music electrically over a distance. Once the family was settled in, both Bell and his father made plans to establish a teaching practice and in 1871, he accompanied his father to Montreal, where Melville was offered a position to teach his System of Visible Speech. == Work with the deaf == Bell's father was invited by Sarah Fuller, principal of the Boston School for Deaf Mutes (which continues today as the public Horace Mann School for the Deaf), in Boston, Massachusetts, United States, to introduce the Visible Speech System by providing training for Fuller's instructors, but he declined the post in favour of his son. Travelling to Boston in April 1871, Bell proved successful in training the school's instructors. He was subsequently asked to repeat the programme at the American Asylum for Deaf-mutes in Hartford, Connecticut, and the Clarke School for the Deaf in Northampton, Massachusetts. Returning home to Brantford after six months abroad, Bell continued his experiments with his "harmonic telegraph". The basic concept behind his device was that messages could be sent through a single wire if each message was transmitted at a different pitch, but work on both the transmitter and receiver was needed.Unsure of his future, he first contemplated returning to London to complete his studies, but decided to return to Boston as a teacher. His father helped him set up his private practice by contacting Gardiner Greene Hubbard, the president of the Clarke School for the Deaf for a recommendation. Teaching his father's system, in October 1872, Alexander Bell opened his "School of Vocal Physiology and Mechanics of Speech" in Boston, which attracted a large number of deaf pupils, with his first class numbering 30 students. While he was working as a private tutor, one of his pupils was Helen Keller, who came to him as a young child unable to see, hear, or speak. She was later to say that Bell dedicated his life to the penetration of that "inhuman silence which separates and estranges". In 1893, Keller performed the sod-breaking ceremony for the construction of Bell's new Volta Bureau, dedicated to "the increase and diffusion of knowledge relating to the deaf".Several influential people of the time, including Bell, viewed deafness as something that should be eradicated, and also believed that with resources and effort, they could teach the deaf to speak and avoid the use of sign language, thus enabling their integration within the wider society from which many were often being excluded. Owing to his efforts to suppress the teaching of sign language, Bell is often viewed negatively by those embracing Deaf culture. == Continuing experimentation == In the following year, Bell became professor of Vocal Physiology and Elocution at the Boston University School of Oratory. During this period, he alternated between Boston and Brantford, spending summers in his Canadian home. At Boston University, Bell was "swept up" by the excitement engendered by the many scientists and inventors residing in the city. He continued his research in sound and endeavored to find a way to transmit musical notes and articulate speech, but although absorbed by his experiments, he found it difficult to devote enough time to experimentation. While days and evenings were occupied by his teaching and private classes, Bell began to stay awake late into the night, running experiment after experiment in rented facilities at his boarding house. Keeping "night owl" hours, he worried that his work would be discovered and took great pains to lock up his notebooks and laboratory equipment. Bell had a specially made table where he could place his notes and equipment inside a locking cover. Worse still, his health deteriorated as he suffered severe headaches. Returning to Boston in fall 1873, Bell made a fateful decision to concentrate on his experiments in sound. Deciding to give up his lucrative private Boston practice, Bell retained only two students, six-year-old "Georgie" Sanders, deaf from birth, and 15-year-old Mabel Hubbard. Each pupil would play an important role in the next developments. George's father, Thomas Sanders, a wealthy businessman, offered Bell a place to stay in nearby Salem with Georgie's grandmother, complete with a room to "experiment". Although the offer was made by George's mother and followed the year-long arrangement in 1872 where her son and his nurse had moved to quarters next to Bell's boarding house, it was clear that Mr. Sanders was backing the proposal. The arrangement was for teacher and student to continue their work together, with free room and board thrown in. Mabel was a bright, attractive girl who was ten years Bell's junior but became the object of his affection. Having lost her hearing after a near-fatal bout of scarlet fever close to her fifth birthday, she had learned to read lips but her father, Gardiner Greene Hubbard, Bell's benefactor and personal friend, wanted her to work directly with her teacher. == The telephone == By 1874, Bell's initial work on the harmonic telegraph had entered a formative stage, with progress made both at his new Boston "laboratory" (a rented facility) and at his family home in Canada a big success. While working that summer in Brantford, Bell experimented with a "phonautograph", a pen-like machine that could draw shapes of sound waves on smoked glass by tracing their vibrations. Bell thought it might be possible to generate undulating electrical currents that corresponded to sound waves. Bell also thought that multiple metal reeds tuned to different frequencies like a harp would be able to convert the undulating currents back into sound. But he had no working model to demonstrate the feasibility of these ideas.In 1874, telegraph message traffic was rapidly expanding and in the words of Western Union President William Orton, had become "the nervous system of commerce". Orton had contracted with inventors Thomas Edison and Elisha Gray to find a way to send multiple telegraph messages on each telegraph line to avoid the great cost of constructing new lines. When Bell mentioned to Gardiner Hubbard and Thomas Sanders that he was working on a method of sending multiple tones on a telegraph wire using a multi-reed device, the two wealthy patrons began to financially support Bell's experiments. Patent matters would be handled by Hubbard's patent attorney, Anthony Pollok.In March 1875, Bell and Pollok visited the scientist Joseph Henry, who was then director of the Smithsonian Institution, and asked Henry's advice on the electrical multi-reed apparatus that Bell hoped would transmit the human voice by telegraph. Henry replied that Bell had "the germ of a great invention". When Bell said that he did not have the necessary knowledge, Henry replied, "Get it!" That declaration greatly encouraged Bell to keep trying, even though he did not have the equipment needed to continue his experiments, nor the ability to create a working model of his ideas. However, a chance meeting in 1874 between Bell and Thomas A. Watson, an experienced electrical designer and mechanic at the electrical machine shop of Charles Williams, changed all that. With financial support from Sanders and Hubbard, Bell hired Thomas Watson as his assistant, and the two of them experimented with acoustic telegraphy. On June 2, 1875, Watson accidentally plucked one of the reeds and Bell, at the receiving end of the wire, heard the overtones of the reed; overtones that would be necessary for transmitting speech. That demonstrated to Bell that only one reed or armature was necessary, not multiple reeds. This led to the "gallows" sound-powered telephone, which could transmit indistinct, voice-like sounds, but not clear speech. === The race to the patent office === In 1875, Bell developed an acoustic telegraph and drew up a patent application for it. Since he had agreed to share U.S. profits with his investors Gardiner Hubbard and Thomas Sanders, Bell requested that an associate in Ontario, George Brown, attempt to patent it in Britain, instructing his lawyers to apply for a patent in the U.S. only after they received word from Britain (Britain would issue patents only for discoveries not previously patented elsewhere). Meanwhile, Elisha Gray was also experimenting with acoustic telegraphy and thought of a way to transmit speech using a water transmitter. On February 14, 1876, Gray filed a caveat with the U.S. Patent Office for a telephone design that used a water transmitter. That same morning, Bell's lawyer filed Bell's application with the patent office. There is considerable debate about who arrived first and Gray later challenged the primacy of Bell's patent. Bell was in Boston on February 14 and did not arrive in Washington until February 26. Bell's patent 174,465, was issued to Bell on March 7, 1876, by the U.S. Patent Office. Bell's patent covered "the method of, and apparatus for, transmitting vocal or other sounds telegraphically ... by causing electrical undulations, similar in form to the vibrations of the air accompanying the said vocal or other sound" Bell returned to Boston the same day and the next day resumed work, drawing in his notebook a diagram similar to that in Gray's patent caveat. On March 10, 1876, three days after his patent was issued, Bell succeeded in getting his telephone to work, using a liquid transmitter similar to Gray's design. Vibration of the diaphragm caused a needle to vibrate in the water, varying the electrical resistance in the circuit. When Bell spoke the sentence "Mr. Watson—Come here—I want to see you" into the liquid transmitter, Watson, listening at the receiving end in an adjoining room, heard the words clearly.Although Bell was, and still is, accused of stealing the telephone from Gray, Bell used Gray's water transmitter design only after Bell's patent had been granted, and only as a proof of concept scientific experiment, to prove to his own satisfaction that intelligible "articulate speech" (Bell's words) could be electrically transmitted. After March 1876, Bell focused on improving the electromagnetic telephone and never used Gray's liquid transmitter in public demonstrations or commercial use.The question of priority for the variable resistance feature of the telephone was raised by the examiner before he approved Bell's patent application. He told Bell that his claim for the variable resistance feature was also described in Gray's caveat. Bell pointed to a variable resistance device in Bell's previous application in which Bell described a cup of mercury, not water. Bell had filed the mercury application at the patent office a year earlier on February 25, 1875, long before Elisha Gray described the water device. In addition, Gray abandoned his caveat, and because he did not contest Bell's priority, the examiner approved Bell's patent on March 3, 1876. Gray had reinvented the variable resistance telephone, but Bell was the first to write down the idea and the first to test it in a telephone.The patent examiner, Zenas Fisk Wilber, later stated in an affidavit that he was an alcoholic who was much in debt to Bell's lawyer, Marcellus Bailey, with whom he had served in the Civil War. He claimed he showed Gray's patent caveat to Bailey. Wilber also claimed (after Bell arrived in Washington D.C. from Boston) that he showed Gray's caveat to Bell and that Bell paid him $100. Bell claimed they discussed the patent only in general terms, although in a letter to Gray, Bell admitted that he learned some of the technical details. Bell denied in an affidavit that he ever gave Wilber any money. === Later developments === Continuing his experiments in Brantford, Bell brought home a working model of his telephone. On August 3, 1876, from the telegraph office in Mount Pleasant five miles (eight km) away from Brantford, Bell sent a tentative telegram indicating that he was ready. With curious onlookers packed into the office as witnesses, faint voices were heard replying. The following night, he amazed guests as well as his family when a message was received at the Bell home from Brantford, four miles (six km) distant, along an improvised wire strung up along telegraph lines and fences, and laid through a tunnel. This time, guests at the household distinctly heard people in Brantford reading and singing. These experiments clearly proved that the telephone could work over long distances. Bell and his partners, Hubbard and Sanders, offered to sell the patent outright to Western Union for $100,000. The president of Western Union balked, countering that the telephone was nothing but a toy. Two years later, he told colleagues that if he could get the patent for $25 million he would consider it a bargain. By then, the Bell company no longer wanted to sell the patent. Bell's investors would become millionaires while he fared well from residuals and at one point had assets of nearly one million dollars.Bell began a series of public demonstrations and lectures to introduce the new invention to the scientific community as well as the general public. A short time later, his demonstration of an early telephone prototype at the 1876 Centennial Exposition in Philadelphia brought the telephone to international attention. Influential visitors to the exhibition included Emperor Pedro II of Brazil. Later, Bell had the opportunity to demonstrate the invention personally to Sir William Thomson (later, Lord Kelvin), a renowned Scottish scientist, as well as to Queen Victoria, who had requested a private audience at Osborne House, her Isle of Wight home. She called the demonstration "most extraordinary". The enthusiasm surrounding Bell's public displays laid the groundwork for universal acceptance of the revolutionary device.The Bell Telephone Company was created in 1877, and by 1886, more than 150,000 people in the U.S. owned telephones. Bell Company engineers made numerous other improvements to the telephone, which emerged as one of the most successful products ever. In 1879, the Bell company acquired Edison's patents for the carbon microphone from Western Union. This made the telephone practical for longer distances, and it was no longer necessary to shout to be heard at the receiving telephone. Emperor Pedro II of Brazil was the first person to buy stock in Bell's company, the Bell Telephone Company. One of the first telephones in a private residence was installed in his palace in Petrópolis, his summer retreat forty miles from Rio de Janeiro.In January 1915, Bell made the first ceremonial transcontinental telephone call. Calling from the AT&T head office at 15 Dey Street in New York City, Bell was heard by Thomas Watson at 333 Grant Avenue in San Francisco. The New York Times reported: On October 9, 1876, Alexander Graham Bell and Thomas A. Watson talked by telephone to each other over a two-mile wire stretched between Cambridge and Boston. It was the first wire conversation ever held. Yesterday afternoon [on January 25, 1915], the same two men talked by telephone to each other over a 3,400-mile wire between New York and San Francisco. Dr. Bell, the veteran inventor of the telephone, was in New York, and Mr. Watson, his former associate, was on the other side of the continent. === Competitors === As is sometimes common in scientific discoveries, simultaneous developments can occur, as evidenced by a number of inventors who were at work on the telephone. Over a period of 18 years, the Bell Telephone Company faced 587 court challenges to its patents, including five that went to the U.S. Supreme Court, but none was successful in establishing priority over the original Bell patent and the Bell Telephone Company never lost a case that had proceeded to a final trial stage. Bell's laboratory notes and family letters were the key to establishing a long lineage to his experiments. The Bell company lawyers successfully fought off myriad lawsuits generated initially around the challenges by Elisha Gray and Amos Dolbear. In personal correspondence to Bell, both Gray and Dolbear had acknowledged his prior work, which considerably weakened their later claims.On January 13, 1887, the U.S. Government moved to annul the patent issued to Bell on the grounds of fraud and misrepresentation. After a series of decisions and reversals, the Bell company won a decision in the Supreme Court, though a couple of the original claims from the lower court cases were left undecided. By the time that the trial wound its way through nine years of legal battles, the U.S. prosecuting attorney had died and the two Bell patents (No. 174,465 dated March 7, 1876, and No. 186,787 dated January 30, 1877) were no longer in effect, although the presiding judges agreed to continue the proceedings due to the case's importance as a precedent. With a change in administration and charges of conflict of interest (on both sides) arising from the original trial, the US Attorney General dropped the lawsuit on November 30, 1897, leaving several issues undecided on the merits.During a deposition filed for the 1887 trial, Italian inventor Antonio Meucci also claimed to have created the first working model of a telephone in Italy in 1834. In 1886, in the first of three cases in which he was involved, Meucci took the stand as a witness in the hopes of establishing his invention's priority. Meucci's testimony in this case was disputed due to a lack of material evidence for his inventions, as his working models were purportedly lost at the laboratory of American District Telegraph (ADT) of New York, which was later incorporated as a subsidiary of Western Union in 1901. Meucci's work, like many other inventors of the period, was based on earlier acoustic principles and despite evidence of earlier experiments, the final case involving Meucci was eventually dropped upon Meucci's death. However, due to the efforts of Congressman Vito Fossella, the U.S. House of Representatives on June 11, 2002, stated that Meucci's "work in the invention of the telephone should be acknowledged". This did not put an end to the still-contentious issue. Some modern scholars do not agree with the claims that Bell's work on the telephone was influenced by Meucci's inventions.The value of the Bell patent was acknowledged throughout the world, and patent applications were made in most major countries, but when Bell delayed the German patent application, the electrical firm of Siemens & Halske (S&H) set up a rival manufacturer of Bell telephones under their own patent. The Siemens company produced near-identical copies of the Bell telephone without having to pay royalties. The establishment of the International Bell Telephone Company in Brussels, Belgium in 1880, as well as a series of agreements in other countries eventually consolidated a global telephone operation. The strain put on Bell by his constant appearances in court, necessitated by the legal battles, eventually resulted in his resignation from the company. == Family life == On July 11, 1877, a few days after the Bell Telephone Company was established, Bell married Mabel Hubbard (1857–1923) at the Hubbard estate in Cambridge, Massachusetts. His wedding present to his bride was to turn over 1,487 of his 1,497 shares in the newly formed Bell Telephone Company. Shortly thereafter, the newlyweds embarked on a year-long honeymoon in Europe. During that excursion, Bell took a handmade model of his telephone with him, making it a "working holiday". The courtship had begun years earlier; however, Bell waited until he was more financially secure before marrying. Although the telephone appeared to be an "instant" success, it was not initially a profitable venture and Bell's main sources of income were from lectures until after 1897. One unusual request exacted by his fiancée was that he use "Alec" rather than the family's earlier familiar name of "Aleck". From 1876, he would sign his name "Alec Bell". They had four children: Elsie May Bell (1878–1964) who married Gilbert Hovey Grosvenor of National Geographic fame. Marian Hubbard Bell (1880–1962) who was referred to as "Daisy". Married David Fairchild. Two sons who died in infancy (Edward in 1881 and Robert in 1883).The Bell family home was in Cambridge, Massachusetts, until 1880 when Bell's father-in-law bought a house in Washington, D.C.; in 1882 he bought a home in the same city for Bell's family, so they could be with him while he attended to the numerous court cases involving patent disputes.Bell was a British subject throughout his early life in Scotland and later in Canada until 1882 when he became a naturalized citizen of the United States. In 1915, he characterized his status as: "I am not one of those hyphenated Americans who claim allegiance to two countries." Despite this declaration, Bell has been proudly claimed as a "native son" by all three countries he resided in: the United States, Canada, and the United Kingdom.By 1885, a new summer retreat was contemplated. That summer, the Bells had a vacation on Cape Breton Island in Nova Scotia, spending time at the small village of Baddeck. Returning in 1886, Bell started building an estate on a point across from Baddeck, overlooking Bras d'Or Lake. By 1889, a large house, christened The Lodge was completed and two years later, a larger complex of buildings, including a new laboratory, were begun that the Bells would name Beinn Bhreagh (Gaelic: beautiful mountain) after Bell's ancestral Scottish highlands. Bell also built the Bell Boatyard on the estate, employing up to 40 people building experimental craft as well as wartime lifeboats and workboats for the Royal Canadian Navy and pleasure craft for the Bell family. He was an enthusiastic boater, and Bell and his family sailed or rowed a long series of vessels on Bras d'Or Lake, ordering additional vessels from the H.W. Embree and Sons boatyard in Port Hawkesbury, Nova Scotia. In his final, and some of his most productive years, Bell split his residency between Washington, D.C., where he and his family initially resided for most of the year, and at Beinn Bhreagh where they spent increasing amounts of time.Until the end of his life, Bell and his family would alternate between the two homes, but Beinn Bhreagh would, over the next 30 years, become more than a summer home as Bell became so absorbed in his experiments that his annual stays lengthened. Both Mabel and Bell became immersed in the Baddeck community and were accepted by the villagers as "their own". The Bells were still in residence at Beinn Bhreagh when the Halifax Explosion occurred on December 6, 1917. Mabel and Bell mobilized the community to help victims in Halifax. == Later inventions == Although Alexander Graham Bell is most often associated with the invention of the telephone, his interests were extremely varied. According to one of his biographers, Charlotte Gray, Bell's work ranged "unfettered across the scientific landscape" and he often went to bed voraciously reading the Encyclopædia Britannica, scouring it for new areas of interest. The range of Bell's inventive genius is represented only in part by the 18 patents granted in his name alone and the 12 he shared with his collaborators. These included 14 for the telephone and telegraph, four for the photophone, one for the phonograph, five for aerial vehicles, four for "hydroairplanes", and two for selenium cells. Bell's inventions spanned a wide range of interests and included a metal jacket to assist in breathing, the audiometer to detect minor hearing problems, a device to locate icebergs, investigations on how to separate salt from seawater, and work on finding alternative fuels. Bell worked extensively in medical research and invented techniques for teaching speech to the deaf. During his Volta Laboratory period, Bell and his associates considered impressing a magnetic field on a record as a means of reproducing sound. Although the trio briefly experimented with the concept, they could not develop a workable prototype. They abandoned the idea, never realizing they had glimpsed a basic principle which would one day find its application in the tape recorder, the hard disc and floppy disc drive, and other magnetic media. Bell's own home used a primitive form of air conditioning, in which fans blew currents of air across great blocks of ice. He also anticipated modern concerns with fuel shortages and industrial pollution. Methane gas, he reasoned, could be produced from the waste of farms and factories. At his Canadian estate in Nova Scotia, he experimented with composting toilets and devices to capture water from the atmosphere. In a magazine interview published shortly before his death, he reflected on the possibility of using solar panels to heat houses. === Photophone === Bell and his assistant Charles Sumner Tainter jointly invented a wireless telephone, named a photophone, which allowed for the transmission of both sounds and normal human conversations on a beam of light. Both men later became full associates in the Volta Laboratory Association. On June 21, 1880, Bell's assistant transmitted a wireless voice telephone message a considerable distance, from the roof of the Franklin School in Washington, D.C., to Bell at the window of his laboratory, some 213 metres (700 ft) away, 19 years before the first voice radio transmissions.Bell believed the photophone's principles were his life's "greatest achievement", telling a reporter shortly before his death that the photophone was "the greatest invention [I have] ever made, greater than the telephone". The photophone was a precursor to the fiber-optic communication systems which achieved popular worldwide usage in the 1980s. Its master patent was issued in December 1880, many decades before the photophone's principles came into popular use. === Metal detector === Bell is also credited with developing one of the early versions of a metal detector in 1881. The device was quickly put together in an attempt to find the bullet in the body of U.S. President James Garfield. According to some accounts, the metal detector worked flawlessly in tests but did not find the assassin's bullet partly because the metal bed frame on which the President was lying disturbed the instrument, resulting in static. The president's surgeons, who were skeptical of the device, ignored Bell's requests to move the president to a bed not fitted with metal springs. Alternatively, although Bell had detected a slight sound on his first test, the bullet may have been lodged too deeply to be detected by the crude apparatus.Bell's own detailed account, presented to the American Association for the Advancement of Science in 1882, differs in several particulars from most of the many and varied versions now in circulation, by concluding that extraneous metal was not to blame for failure to locate the bullet. Perplexed by the peculiar results he had obtained during an examination of Garfield, Bell "proceeded to the Executive Mansion the next morning ... to ascertain from the surgeons whether they were perfectly sure that all metal had been removed from the neighborhood of the bed. It was then recollected that underneath the horse-hair mattress on which the President lay was another mattress composed of steel wires. Upon obtaining a duplicate, the mattress was found to consist of a sort of net of woven steel wires, with large meshes. The extent of the [area that produced a response from the detector] having been so small, as compared with the area of the bed, it seemed reasonable to conclude that the steel mattress had produced no detrimental effect." In a footnote, Bell adds, "The death of President Garfield and the subsequent post-mortem examination, however, proved that the bullet was at too great a distance from the surface to have affected our apparatus." === Hydrofoils === The March 1906 Scientific American article by American pioneer William E. Meacham explained the basic principle of hydrofoils and hydroplanes. Bell considered the invention of the hydroplane as a very significant achievement. Based on information gained from that article, he began to sketch concepts of what is now called a hydrofoil boat. Bell and assistant Frederick W. "Casey" Baldwin began hydrofoil experimentation in the summer of 1908 as a possible aid to airplane takeoff from water. Baldwin studied the work of the Italian inventor Enrico Forlanini and began testing models. This led him and Bell to the development of practical hydrofoil watercraft. During his world tour of 1910–11, Bell and Baldwin met with Forlanini in France. They had rides in the Forlanini hydrofoil boat over Lake Maggiore. Baldwin described it as being as smooth as flying. On returning to Baddeck, a number of initial concepts were built as experimental models, including the Dhonnas Beag (Scottish Gaelic for little devil), the first self-propelled Bell-Baldwin hydrofoil. The experimental boats were essentially proof-of-concept prototypes that culminated in the more substantial HD-4, powered by Renault engines. A top speed of 54 miles per hour (87 km/h) was achieved, with the hydrofoil exhibiting rapid acceleration, good stability, and steering, along with the ability to take waves without difficulty. In 1913, Dr. Bell hired Walter Pinaud, a Sydney yacht designer and builder as well as the proprietor of Pinaud's Yacht Yard in Westmount, Nova Scotia to work on the pontoons of the HD-4. Pinaud soon took over the boatyard at Bell Laboratories on Beinn Bhreagh, Bell's estate near Baddeck, Nova Scotia. Pinaud's experience in boat-building enabled him to make useful design changes to the HD-4. After the First World War, work began again on the HD-4. Bell's report to the U.S. Navy permitted him to obtain two 350 horsepower (260 kilowatts) engines in July 1919. On September 9, 1919, the HD-4 set a world marine speed record of 70.86 miles per hour (114.04 kilometres per hour), a record which stood for ten years. === Aeronautics === In 1891, Bell had begun experiments to develop motor-powered heavier-than-air aircraft. The AEA was first formed as Bell shared the vision to fly with his wife, who advised him to seek "young" help as Bell was at the age of 60. In 1898, Bell experimented with tetrahedral box kites and wings constructed of multiple compound tetrahedral kites covered in maroon silk. The tetrahedral wings were named Cygnet I, II, and III, and were flown both unmanned and manned (Cygnet I crashed during a flight carrying Selfridge) in the period from 1907–1912. Some of Bell's kites are on display at the Alexander Graham Bell National Historic Site.Bell was a supporter of aerospace engineering research through the Aerial Experiment Association (AEA), officially formed at Baddeck, Nova Scotia, in October 1907 at the suggestion of his wife Mabel and with her financial support after the sale of some of her real estate. The AEA was headed by Bell and the founding members were four young men: American Glenn H. Curtiss, a motorcycle manufacturer at the time and who held the title "world's fastest man", having ridden his self-constructed motor bicycle around in the shortest time, and who was later awarded the Scientific American Trophy for the first official one-kilometre flight in the Western hemisphere, and who later became a world-renowned airplane manufacturer; Lieutenant Thomas Selfridge, an official observer from the U.S. Federal government and one of the few people in the army who believed that aviation was the future; Frederick W. Baldwin, the first Canadian and first British subject to pilot a public flight in Hammondsport, New York, and J. A .D. McCurdy–Baldwin and McCurdy being new engineering graduates from the University of Toronto.The AEA's work progressed to heavier-than-air machines, applying their knowledge of kites to gliders. Moving to Hammondsport, the group then designed and built the Red Wing, framed in bamboo and covered in red silk and powered by a small air-cooled engine. On March 12, 1908, over Keuka Lake, the biplane lifted off on the first public flight in North America. The innovations that were incorporated into this design included a cockpit enclosure and tail rudder (later variations on the original design would add ailerons as a means of control). One of the AEA's inventions, a practical wingtip form of the aileron, was to become a standard component on all aircraft. The White Wing and June Bug were to follow and by the end of 1908, over 150 flights without mishap had been accomplished. However, the AEA had depleted its initial reserves and only a $15,000 grant from Mrs. Bell allowed it to continue with experiments. Lt. Selfridge had also become the first person killed in a powered heavier-than-air flight in a crash of the Wright Flyer at Fort Myer, Virginia, on September 17, 1908. Their final aircraft design, the Silver Dart, embodied all of the advancements found in the earlier machines. On February 23, 1909, Bell was present as the Silver Dart flown by J. A. D. McCurdy from the frozen ice of Bras d'Or made the first aircraft flight in Canada. Bell had worried that the flight was too dangerous and had arranged for a doctor to be on hand. With the successful flight, the AEA disbanded and the Silver Dart would revert to Baldwin and McCurdy who began the Canadian Aerodrome Company and would later demonstrate the aircraft to the Canadian Army. == Eugenics == Bell was connected with the eugenics movement in the United States. In his lecture Memoir upon the formation of a deaf variety of the human race presented to the National Academy of Sciences on November 13, 1883, he noted that congenitally deaf parents were more likely to produce deaf children and tentatively suggested that couples where both parties were deaf should not marry. However, it was his hobby of livestock breeding which led to his appointment to biologist David Starr Jordan's Committee on Eugenics, under the auspices of the American Breeders' Association. The committee unequivocally extended the principle to humans. From 1912 until 1918, he was the chairman of the board of scientific advisers to the Eugenics Record Office associated with Cold Spring Harbor Laboratory in New York, and regularly attended meetings. In 1921, he was the honorary president of the Second International Congress of Eugenics held under the auspices of the American Museum of Natural History in New York. Organizations such as these advocated passing laws (with success in some states) that established the compulsory sterilization of people deemed to be, as Bell called them, a "defective variety of the human race". By the late 1930s, about half the states in the U.S. had eugenics laws, and California's compulsory sterilization law was used as a model for that of Nazi Germany. == Legacy and honors == Honors and tributes flowed to Bell in increasing numbers as his invention became ubiquitous and his personal fame grew. Bell received numerous honorary degrees from colleges and universities to the point that the requests almost became burdensome. During his life, he also received dozens of major awards, medals, and other tributes. These included statuary monuments to both him and the new form of communication his telephone created, including the Bell Telephone Memorial erected in his honor in Alexander Graham Bell Gardens in Brantford, Ontario, in 1917.A large number of Bell's writings, personal correspondence, notebooks, papers, and other documents reside in both the United States Library of Congress Manuscript Division (as the Alexander Graham Bell Family Papers), and at the Alexander Graham Bell Institute, Cape Breton University, Nova Scotia; major portions of which are available for online viewing. A number of historic sites and other marks commemorate Bell in North America and Europe, including the first telephone companies in the United States and Canada. Among the major sites are: The Alexander Graham Bell National Historic Site, maintained by Parks Canada, which incorporates the Alexander Graham Bell Museum, in Baddeck, Nova Scotia, close to the Bell estate Beinn Bhreagh The Bell Homestead National Historic Site, includes the Bell family home, "Melville House", and farm overlooking Brantford, Ontario and the Grand River. It was their first home in North America; Canada's first telephone company building, the "Henderson Home" of the late 1870s, a predecessor of the Bell Telephone Company of Canada (officially chartered in 1880). In 1969, the building was carefully moved to the historic Bell Homestead National Historic Site in Brantford, Ontario, and was refurbished to become a telephone museum. The Bell Homestead, the Henderson Home telephone museum, and the National Historic Site's reception centre are all maintained by the Bell Homestead Society; The Alexander Graham Bell Memorial Park, which features a broad neoclassical monument built in 1917 by public subscription. The monument depicts mankind's ability to span the globe through telecommunications; The Alexander Graham Bell Museum (opened in 1956), part of the Alexander Graham Bell National Historic Site which was completed in 1978 in Baddeck, Nova Scotia. Many of the museum's artifacts were donated by Bell's daughters;In 1880, Bell received the Volta Prize with a purse of 50,000 francs (approximately US$260,000 in today's dollars) for the invention of the telephone from the Académie française, representing the French government. Among the luminaries who judged were Victor Hugo and Alexandre Dumas. The Volta Prize was conceived by Napoleon Bonaparte in 1801, and named in honor of Alessandro Volta, with Bell receiving the third grand prize in its history. Since Bell was becoming increasingly affluent, he used his prize money to create endowment funds (the 'Volta Fund') and institutions in and around the United States capital of Washington, D.C.. These included the prestigious 'Volta Laboratory Association' (1880), also known as the Volta Laboratory and as the 'Alexander Graham Bell Laboratory', and which eventually led to the Volta Bureau (1887) as a center for studies on deafness which is still in operation in Georgetown, Washington, D.C. The Volta Laboratory became an experimental facility devoted to scientific discovery, and the very next year it improved Edison's phonograph by substituting wax for tinfoil as the recording medium and incising the recording rather than indenting it, key upgrades that Edison himself later adopted. The laboratory was also the site where he and his associate invented his "proudest achievement", "the photophone", the "optical telephone" which presaged fibre optical telecommunications while the Volta Bureau would later evolve into the Alexander Graham Bell Association for the Deaf and Hard of Hearing (the AG Bell), a leading center for the research and pedagogy of deafness. In partnership with Gardiner Greene Hubbard, Bell helped establish the publication Science during the early 1880s. In 1898, Bell was elected as the second president of the National Geographic Society, serving until 1903, and was primarily responsible for the extensive use of illustrations, including photography, in the magazine. He also served for many years as a Regent of the Smithsonian Institution (1898–1922). The French government conferred on him the decoration of the Légion d'honneur (Legion of Honor); the Royal Society of Arts in London awarded him the Albert Medal in 1902; the University of Würzburg, Bavaria, granted him a PhD, and he was awarded the Franklin Institute's Elliott Cresson Medal in 1912. He was one of the founders of the American Institute of Electrical Engineers in 1884 and served as its president from 1891–92. Bell was later awarded the AIEE's Edison Medal in 1914 "For meritorious achievement in the invention of the telephone".The bel (B) and the smaller decibel (dB) are units of measurement of sound intensity invented by Bell Labs and named after him. Since 1976, the IEEE's Alexander Graham Bell Medal has been awarded to honor outstanding contributions in the field of telecommunications. In 1936, the US Patent Office declared Bell first on its list of the country's greatest inventors, leading to the US Post Office issuing a commemorative stamp honoring Bell in 1940 as part of its 'Famous Americans Series'. The First Day of Issue ceremony was held on October 28 in Boston, Massachusetts, the city where Bell spent considerable time on research and working with the deaf. The Bell stamp became very popular and sold out in little time. The stamp became and remains to this day, the most valuable one of the series.The 150th anniversary of Bell's birth in 1997 was marked by a special issue of commemorative £1 banknotes from the Royal Bank of Scotland. The illustrations on the reverse of the note include Bell's face in profile, his signature, and objects from Bell's life and career: users of the telephone over the ages; an audio wave signal; a diagram of a telephone receiver; geometric shapes from engineering structures; representations of sign language and the phonetic alphabet; the geese which helped him to understand flight; and the sheep which he studied to understand genetics. Additionally, the Government of Canada honored Bell in 1997 with a C$100 gold coin, in tribute also to the 150th anniversary of his birth, and with a silver dollar coin in 2009 in honor of the 100th anniversary of flight in Canada. That first flight was made by an airplane designed under Dr. Bell's tutelage, named the Silver Dart. Bell's image, and also those of his many inventions have graced paper money, coinage, and postal stamps in numerous countries worldwide for many dozens of years. Alexander Graham Bell was ranked 57th among the 100 Greatest Britons (2002) in an official BBC nationwide poll, and among the Top Ten Greatest Canadians (2004), and the 100 Greatest Americans (2005). In 2006, Bell was also named as one of the 10 greatest Scottish scientists in history after having been listed in the National Library of Scotland's 'Scottish Science Hall of Fame'. Bell's name is still widely known and used as part of the names of dozens of educational institutes, corporate namesakes, street and place names around the world. === Honorary degrees === Alexander Graham Bell, who could not complete the university program of his youth, received at least a dozen honorary degrees from academic institutions, including eight honorary LL.D.s (Doctorate of Laws), two Ph.D.s, a D.Sc., and an M.D.: Gallaudet College (then named National Deaf-Mute College) in Washington, D.C. (Ph.D.) in 1880 University of Würzburg in Würzburg, Bavaria (Ph.D.) in 1882 Heidelberg University in Heidelberg, Germany (M.D.) in 1886 Harvard University in Cambridge, Massachusetts (LL.D.) in 1896 Illinois College, in Jacksonville, Illinois (LL.D.) in 1896, possibly 1881 Amherst College in Amherst, Massachusetts (LL.D.) in 1901 St. Andrew's University in St Andrews, Scotland (LL.D) in 1902 University of Oxford in Oxford, England (D.Sc.) in 1906 University of Edinburgh in Edinburgh, Scotland (LL.D.) in 1906 George Washington University in Washington, D.C. (LL.D.) in 1913 Queen's University in Kingston, Ontario, Canada (LL.D.) in 1908 Dartmouth College in Hanover, New Hampshire (LL.D.) in 1913, possibly 1914 == Innovators awarded in his name == Aegis Graham Bell Award are consistuted to recognise good work by innovators in India. Since 2010 awards are being given to innovators in IT and Telecom sector. Companies like Mahendra Tech, Data Infosys, CDOT, Infosys etc. have been awarded for the same. == Portrayal in film and television == The 1939 film The Story of Alexander Graham Bell was based on his life and works. The 1992 film The Sound and the Silence was a TV film. Biography aired an episode Alexander Graham Bell: Voice of Invention on 6 August 1996. Eyewitness No. 90 A Great Inventor Is Remembered, a 1957 NFB short about Bell. == Death == Bell died of complications arising from diabetes on August 2, 1922, at his private estate in Cape Breton, Nova Scotia, at age 75. Bell had also been afflicted with pernicious anemia. His last view of the land he had inhabited was by moonlight on his mountain estate at 2:00 a.m. While tending to him after his long illness, Mabel, his wife, whispered, "Don't leave me." By way of reply, Bell signed "no...", lost consciousness, and died shortly after.On learning of Bell's death, the Canadian Prime Minister, Mackenzie King, cabled Mrs. Bell, saying: My colleagues in the Government join with me in expressing to you our sense of the world's loss in the death of your distinguished husband. It will ever be a source of pride to our country that the great invention, with which his name is immortally associated, is a part of its history. On the behalf of the citizens of Canada, may I extend to you an expression of our combined gratitude and sympathy. Bell's coffin was constructed of Beinn Bhreagh pine by his laboratory staff, lined with the same red silk fabric used in his tetrahedral kite experiments. To help celebrate his life, his wife asked guests not to wear black (the traditional funeral color) while attending his service, during which soloist Jean MacDonald sang a verse of Robert Louis Stevenson's "Requiem": Under a wide and starry sky, Dig the grave and let me lie. Glad did I live and gladly die And I laid me down with a will.Upon the conclusion of Bell's funeral, "every phone on the continent of North America was silenced in honor of the man who had given to mankind the means for direct communication at a distance".Dr. Alexander Graham Bell was buried atop Beinn Bhreagh mountain, on his estate where he had resided increasingly for the last 35 years of his life, overlooking Bras d'Or Lake. He was survived by his wife Mabel, his two daughters, Elsie May and Marian, and nine of his grandchildren. == See also == == References == === Notes === === Citations === === Bibliography === === Further reading === Mullett, Mary B.

### Instruction: retrieve labels for this: Anatolia (from Ἀνατολή Anatolḗ; Turkish: Anadolu "east" or "[sun]rise"), also known as Asia Minor (Medieval and Modern Greek: Μικρά Ἀσία Mikrá Asía, "small Asia"; Turkish: Küçük Asya), Asian Turkey, the Anatolian peninsula, or the Anatolian plateau, is the westernmost protrusion of Asia, which makes up the majority of modern-day Turkey. The region is bounded by the Black Sea to the north, the Mediterranean Sea to the south, and the Aegean Sea to the west. The Sea of Marmara forms a connection between the Black and Aegean Seas through the Bosphorus and Dardanelles straits and separates Anatolia from Thrace on the European mainland. Traditionally, Anatolia is considered to extend in the east to a line between the Gulf of Alexandretta and the Black Sea to the Armenian Highlands (Armenia Major). This region is now named and largely situated in the Eastern Anatolia Region of the far north east of Turkey and converges with the Lesser Caucasus – an area that was incorporated in the Russian Empire region of Transcaucasia in the 19th century. Thus, traditionally Anatolia is the territory that comprises approximately the western two-thirds of the Asian part of Turkey. Anatolia is often considered to be synonymous with Asian Turkey, which comprises almost the entire country; its eastern and southeastern borders are widely taken to be the Turkish borders with neighboring Georgia, Armenia, Azerbaijan, Iran, Iraq, and Syria, in clockwise direction. The ancient inhabitants of Anatolia spoke the now-extinct Anatolian languages, which were largely replaced by the Greek language starting from classical antiquity and during the Hellenistic, Roman and Byzantine periods. Major Anatolian languages included Hittite, Luwian, and Lydian among other more poorly attested relatives. The Turkification of Anatolia began under the Seljuk Empire in the late 11th century and continued under the Ottoman Empire between the early 14th and early 20th centuries. However, various non-Turkic languages continue to be spoken by minorities in Anatolia today, including Kurdish, Neo-Aramaic, Armenian, Arabic, Laz, Georgian and Greek. Other ancient peoples in the region included Galatians, Hurrians, Assyrians, Hattians, Cimmerians, as well as Ionian, Dorian, and Aeolian Greeks. == Definition == The Anatolian peninsula, also called Asia Minor, is bounded by the Black Sea to the north, the Mediterranean Sea to the south, the Aegean Sea to the west, and the Sea of Marmara to the northwest, which separates Anatolia from Thrace in Europe. Traditionally, Anatolia is considered to extend in the east to an indefinite line running from the Gulf of Alexandretta to the Black Sea, coterminous with the Anatolian Plateau. This traditional geographical definition is used, for example, in the latest edition of Merriam-Webster's Geographical Dictionary, as well as the archeological community. Under this definition, Anatolia is bounded to the east by the Armenian Highlands, and the Euphrates before that river bends to the southeast to enter Mesopotamia. To the southeast, it is bounded by the ranges that separate it from the Orontes valley in Syria (region) and the Mesopotamian plain.Following the Armenian Genocide and establishment of the Republic of Turkey, the Armenian Highlands (or Western Armenia) were renamed "Eastern Anatolia" (literally The Eastern East) by the Turkish government, being effectively co-terminous with Asian Turkey. Turkey's First Geography Congress in 1941 created two regions to the east of the Gulf of Iskenderun-Black Sea line named the Eastern Anatolia Region and the Southeastern Anatolia Region, the former largely corresponding to the western part of the Armenian Highland, the latter to the northern part of the Mesopotamian plain. This wider definition of Anatolia has gained widespread currency outside of Turkey and has, for instance, been adopted by Encyclopædia Britannica and other encyclopedic and general reference publications. Vazken Davidian terms the expanded use of "Anatolia" to apply to territory formerly referred to as Armenia as "an historical imposition", and notes that a growing body of literature is uncomfortable with referring to the Ottoman East as "Eastern Anatolia". == Onomastics and etymology == The oldest known reference to Anatolia – as “Land of the Hatti” – appears on Mesopotamian cuneiform tablets from the period of the Akkadian Empire (2350–2150 BC). The first recorded name the Greeks used for the Anatolian peninsula, Ἀσία (Asía), presumably echoed the name of the Assuwa league in western Anatolia. As the name "Asia" broadened its scope to apply to other areas east of the Mediterranean, Greeks in Late Antiquity came to use the name Μικρὰ Ἀσία (Mikrá Asía) or Asia Minor, meaning "Lesser Asia" to refer to present-day Anatolia. The English-language name Anatolia itself derives from the Greek ἀνατολή (anatolḗ) meaning “the East” or more literally “sunrise” (comparable to the Latin-derived terms "levant" and "orient"). The precise reference of this term has varied over time, perhaps originally referring to the Aeolian, Ionian and Dorian colonies on the west coast of Asia Minor. In the Byzantine Empire, the Anatolic Theme (Ἀνατολικόν θέμα) was a theme covering the western and central parts of Turkey's present-day Central Anatolia Region.The term "Anatolia" is Medieval Latin.The modern Turkish form of Anatolia, Anadolu, derives from the Greek name Aνατολή (Anatolḗ). The Russian male name Anatoly and the French Anatole share the same linguistic origin. In English the name of Turkey for ancient Anatolia first appeared c. 1369. It derives from the Medieval Latin Turchia (meaning “Land of the Turks”, Turkish Türkiye), a name originally used by Europeans to designate those parts of Anatolia controlled by the Seljuk Sultanate of Rum after the Battle of Manzikert (1071). == History == === Prehistory === Human habitation in Anatolia dates back to the Paleolithic. Neolithic Anatolia has been proposed as the homeland of the Indo-European language family, although linguists tend to favour a later origin in the steppes north of the Black Sea. However, it is clear that the Anatolian languages, the oldest attested branch of Indo-European, have been spoken in Anatolia since at least the 19th century BC. === Ancient Near East (Bronze and Iron Ages) === ==== Hattians and Hurrians ==== The earliest historical records of Anatolia stem from the southeast of the region and are from the Mesopotamian-based Akkadian Empire during the reign of Sargon of Akkad in the 24th century BC. Scholars generally believe the earliest indigenous populations of Anatolia were the Hattians and Hurrians. The Hattians spoke a language of unclear affiliation, and the Hurrian language belongs to a small family called Hurro-Urartian, all these languages now being extinct; relationships with indigenous languages of the Caucasus have been proposed but are not generally accepted. The region was famous for exporting raw materials, and areas of Hattian- and Hurrian-populated southeast Anatolia were colonised by the Akkadians. ==== Assyrian Empire (21st–18th centuries BC) ==== After the fall of the Akkadian Empire in the mid-21st century BC, the Assyrians, who were the northern branch of the Akkadian people, colonised parts of the region between the 21st and mid-18th centuries BC and claimed its resources, notably silver. One of the numerous cuneiform records dated circa 20th century BC, found in Anatolia at the Assyrian colony of Kanesh, uses an advanced system of trading computations and credit lines. ==== Hittite Kingdom and Empire (17th–12th centuries BC) ==== Unlike the Akkadians and their descendants, the Assyrians, whose Anatolian possessions were peripheral to their core lands in Mesopotamia, the Hittites were centred at Hattusa (modern Boğazkale) in north-central Anatolia by the 17th century BC. They were speakers of an Indo-European language, the Hittite language, or nesili (the language of Nesa) in Hittite. Attested for the first time in the Assyrian tablets of Nesa around 2000BC, they conquered Hattusa in the 18th century BC, imposing themselves over Hattian- and Hurrian-speaking populations. According to the widely accepted Kurgan theory on the Proto-Indo-European homeland, however, the Hittites (along with the other Indo-European ancient Anatolians) were themselves relatively recent immigrants to Anatolia from the north. The Hittites adopted the cuneiform script, invented in Mesopotamia. During the Late Bronze Age circa 1650 BC, they created a kingdom, the Hittite New Kingdom, which became an empire in the 14th century BC after the conquest of Kizzuwatna in the south-east and the defeat of the Assuwa league in western Anatolia. The empire reached its height in the 13th century BC, controlling much of Asia Minor, northwestern Syria and northwest upper Mesopotamia. They failed to reach the Anatolian coasts of the Black Sea, however, as a non-Indo-European people, the semi-nomadic pastoralist and tribal Kaskians, had established themselves there, displacing earlier Palaic-speaking Indo-Europeans. Much of the history of the Hittite Empire concerned war with the rival empires of Egypt, Assyria and the Mitanni.The Egyptians eventually withdrew from the region after failing to gain the upper hand over the Hittites and becoming wary of the power of Assyria, which had destroyed the Mitanni Empire. The Assyrians and Hittites were then left to battle over control of eastern and southern Anatolia and colonial territories in Syria. The Assyrians had better success than the Egyptians, annexing much Hittite (and Hurrian) territory in these regions. ==== Neo-Hittite kingdoms (c. 1180–700 BC) ==== After 1180 BC, during the Late Bronze Age collapse, the Hittite empire disintegrated into several independent Syro-Hittite states, subsequent to losing much territory to the Middle Assyrian Empire and being finally overrun by the Phrygians, another Indo-European people who are believed to have migrated from the Balkans. The Phrygian expansion into southeast Anatolia was eventually halted by the Assyrians, who controlled that region. ArameansArameans encroached over the borders of south central Anatolia in the century or so after the fall of the Hittite empire, and some of the Syro-Hittite states in this region became an amalgam of Hittites and Arameans. These became known as Syro-Hittite states. Luwians In central and western Anatolia, another Indo-European people, the Luwians, came to the fore, circa 2000 BC. Their language was closely related to Hittite. The general consensus amongst scholars is that Luwian was spoken—to a greater or lesser degree—across a large area of western Anatolia, including (possibly) Wilusa (Troy), the Seha River Land (to be identified with the Hermos and/or Kaikos valley), and the kingdom of Mira-Kuwaliya with its core territory of the Maeander valley. From the 9th century BC, Luwian regions coalesced into a number of states such as Lydia, Caria and Lycia, all of which had Hellenic influence. ==== Neo-Assyrian Empire (10th–7th centuries BC) ==== From the 10th to late 7th centuries BC, much of Anatolia (particularly the east, central, and southeastern regions) fell to the Neo-Assyrian Empire, including all of the Syro-Hittite states, Tabal, Kingdom of Commagene, the Cimmerians and Scythians and swathes of Cappadocia. The Neo-Assyrian empire collapsed due to a bitter series of civil wars followed by a combined attack by Medes, Persians, Scythians and their own Babylonian relations. The last Assyrian city to fall was Harran in southeast Anatolia. This city was the birthplace of the last king of Babylon, the Assyrian Nabonidus and his son and regent Belshazzar. Much of the region then fell to the short-lived Iran-based Median Empire, with the Babylonians and Scythians briefly appropriating some territory. ==== Cimmerian and Scythian invasions (8th–7th centuries BC) ==== From the late 8th century BC, a new wave of Indo-European-speaking raiders entered northern and northeast Anatolia: the Cimmerians and Scythians. The Cimmerians overran Phrygia and the Scythians threatened to do the same to Urartu and Lydia, before both were finally checked by the Assyrians. ==== Greek West ==== The north-western coast of Anatolia was inhabited by Greeks of the Achaean/Mycenaean culture from the 20th century BC, related to the Greeks of south eastern Europe and the Aegean. Beginning with the Bronze Age collapse at the end of the 2nd millennium BC, the west coast of Anatolia was settled by Ionian Greeks, usurping the area of the related but earlier Mycenaean Greeks. Over several centuries, numerous Ancient Greek city-states were established on the coasts of Anatolia. Greeks started Western philosophy on the western coast of Anatolia (Pre-Socratic philosophy). === Classical antiquity === In classical antiquity, Anatolia was described by Herodotus and later historians as divided into regions named after tribes such as Lydia, Lycia, Caria, Mysia, Bithynia, Phrygia, Galatia, Lycaonia, Pisidia, Paphlagonia, Cilicia, and Cappadocia. By that time, the populations were a mixture of the ancient Anatolian or "Syro-Hittite" substrate and post-Bronze-Age-collapse "Thraco-Phrygian" and more recent Greco-Macedonian incursions. Anatolia is known as the birthplace of minted coinage (as opposed to unminted coinage, which first appears in Mesopotamia at a much earlier date) as a medium of exchange, some time in the 7th century BC in Lydia. The use of minted coins continued to flourish during the Greek and Roman eras.During the 6th century BC, all of Anatolia was conquered by the Persian Achaemenid Empire, the Persians having usurped the Medes as the dominant dynasty in Iran. In 499 BC, the Ionian city-states on the west coast of Anatolia rebelled against Persian rule. The Ionian Revolt, as it became known, though quelled, initiated the Greco-Persian Wars, which ended in a Greek victory in 449 BC, and the Ionian cities regained their independence, alongside the withdrawal of the Persian forces from their European territories. In 334 BC, the Macedonian Greek king Alexander the Great conquered the peninsula from the Achaemenid Persian Empire. Alexander's conquest opened up the interior of Asia Minor to Greek settlement and influence. Following the death of Alexander and the breakup of his empire, Anatolia was ruled by a series of Hellenistic kingdoms, such as the Attalids of Pergamum and the Seleucids, the latter controlling most of Anatolia. A period of peaceful Hellenization followed, such that the local Anatolian languages had been supplanted by Greek by the 1st century BC. In 133 BC the last Attalid king bequeathed his kingdom to the Roman Republic, and western and central Anatolia came under Roman control, but Hellenistic culture remained predominant. Further annexations by Rome, in particular of the Kingdom of Pontus by Pompey, brought all of Anatolia under Roman control, except for the eastern frontier with the Parthian Empire, which remained unstable for centuries, causing a series of wars, culminating in the Roman-Parthian Wars. === Early Christian period === After the division of the Roman Empire, Anatolia became part of the East Roman, or Byzantine Empire. Anatolia was one of the first places where Christianity spread, so that by the 4th century AD, western and central Anatolia were overwhelmingly Christian and Greek-speaking. For the next 600 years, while Imperial possessions in Europe were subjected to barbarian invasions, Anatolia would be the center of the Hellenic world. Byzantine control was challenged by Arab raids starting in the eighth century (see Arab–Byzantine wars), but in the ninth and tenth century a resurgent Byzantine Empire regained its lost territories, including even long lost territory such as Armenia and Syria (ancient Aram). === Late medieval period === In the 10 years following the Battle of Manzikert in 1071, the Seljuk Turks from Central Asia migrated over large areas of Anatolia, with particular concentrations around the northwestern rim. The Turkish language and the Islamic religion were gradually introduced as a result of the Seljuk conquest, and this period marks the start of Anatolia's slow transition from predominantly Christian and Greek-speaking, to predominantly Muslim and Turkish-speaking (although ethnic groups such as Armenians, Greeks, and Assyrians remained numerous and retained Christianity and their native languages). In the following century, the Byzantines managed to reassert their control in western and northern Anatolia. Control of Anatolia was then split between the Byzantine Empire and the Seljuk Sultanate of Rûm, with the Byzantine holdings gradually being reduced.In 1255, the Mongols swept through eastern and central Anatolia, and would remain until 1335. The Ilkhanate garrison was stationed near Ankara. After the decline of the Ilkhanate from 1335–1353, the Mongol Empire's legacy in the region was the Uyghur Eretna Dynasty that was overthrown by Kadi Burhan al-Din in 1381.By the end of the 14th century, most of Anatolia was controlled by various Anatolian beyliks. Smyrna fell in 1330, and the last Byzantine stronghold in Anatolia, Philadelphia, fell in 1390. The Turkmen Beyliks were under the control of the Mongols, at least nominally, through declining Seljuk sultans. The Beyliks did not mint coins in the names of their own leaders while they remained under the suzerainty of the Mongol Ilkhanids. The Osmanli ruler Osman I was the first Turkish ruler who minted coins in his own name in 1320s, for it bears the legend "Minted by Osman son of Ertugul". Since the minting of coins was a prerogative accorded in Islamic practice only to a sovereign, it can be considered that the Osmanli, or Ottoman Turks, became formally independent from the Mongol Khans. === Ottoman Empire === Among the Turkish leaders, the Ottomans emerged as great power under Osman I and his son Orhan I.The Anatolian beyliks were successively absorbed into the rising Ottoman Empire during the 15th century. It is not well understood how the Osmanlı, or Ottoman Turks, came to dominate their neighbours, as the history of medieval Anatolia is still little known. The Ottomans completed the conquest of the peninsula in 1517 with the taking of Halicarnassus (modern Bodrum) from the Knights of Saint John. === Modern times === With the acceleration of the decline of the Ottoman Empire in the early 19th century, and as a result of the expansionist policies of Tsarist Russia in the Caucasus, many Muslim nations and groups in that region, mainly Circassians, Tatars, Azeris, Lezgis, Chechens and several Turkic groups left their homelands and settled in Anatolia. As the Ottoman Empire further shrank in the Balkan regions and then fragmented during the Balkan Wars, much of the non-Christian populations of its former possessions, mainly Balkan Muslims (Bosnian Muslims, Albanians, Turks, Muslim Bulgarians and Greek Muslims such as the Vallahades from Greek Macedonia), were resettled in various parts of Anatolia, mostly in formerly Christian villages throughout Anatolia. A continuous reverse migration occurred since the early 19th century, when Greeks from Anatolia, Constantinople and Pontus area migrated toward the newly independent Kingdom of Greece, and also towards the United States, southern part of the Russian Empire, Latin America and rest of Europe. Following the Russo-Persian Treaty of Turkmenchay (1828) and the incorporation of the Eastern Armenia into the Russian Empire, another migration involved the large Armenian population of Anatolia, which recorded significant migration rates from Western Armenia (Eastern Anatolia) toward the Russian Empire, especially toward its newly established Armenian provinces. Anatolia remained multi-ethnic until the early 20th century (see the rise of nationalism under the Ottoman Empire). During World War I, the Armenian Genocide, the Greek genocide (especially in Pontus), and the Assyrian genocide almost entirely removed the ancient indigenous communities of Armenian, Greek, and Assyrian populations in Anatolia and surrounding regions. Following the Greco-Turkish War of 1919–1922, most remaining ethnic Anatolian Greeks were forced out during the 1923 population exchange between Greece and Turkey. Many more have left Turkey since, leaving fewer than 5,000 Greeks in Anatolia today. Since the foundation of the Republic of Turkey in 1923, Anatolia has been within Turkey, its inhabitants being mainly Turks and Kurds (see demographics of Turkey and history of Turkey). == Geography == === Geology === Anatolia's terrain is structurally complex. A central massif composed of uplifted blocks and downfolded troughs, covered by recent deposits and giving the appearance of a plateau with rough terrain, is wedged between two folded mountain ranges that converge in the east. True lowland is confined to a few narrow coastal strips along the Aegean, Mediterranean, and Black Sea coasts. Flat or gently sloping land is rare and largely confined to the deltas of the Kızıl River, the coastal plains of Çukurova and the valley floors of the Gediz River and the Büyük Menderes River as well as some interior high plains in Anatolia, mainly around Lake Tuz (Salt Lake) and the Konya Basin (Konya Ovasi). === Climate === Temperatures of Anatolia Anatolia has a varied range of climates. The central plateau is characterized by a continental climate, with hot summers and cold snowy winters. The south and west coasts enjoy a typical Mediterranean climate, with mild rainy winters, and warm dry summers. The Black Sea and Marmara coasts have a temperate oceanic climate, with cool foggy summers and much rainfall throughout the year. === Ecoregions === There is a diverse number of plant and animal communities. The mountains and coastal plain of northern Anatolia experiences humid and mild climate. There are temperate broadleaf, mixed and coniferous forests. The central and eastern plateau, with its drier continental climate, has deciduous forests and forest steppes. Western and southern Anatolia, which have a Mediterranean climate, contain Mediterranean forests, woodlands, and scrub ecoregions. Euxine-Colchic deciduous forests: These temperate broadleaf and mixed forests extend across northern Anatolia, lying between the mountains of northern Anatolia and the Black Sea. They include the enclaves of temperate rainforest lying along the southeastern coast of the Black Sea in eastern Turkey and Georgia. Northern Anatolian conifer and deciduous forests: These forests occupy the mountains of northern Anatolia, running east and west between the coastal Euxine-Colchic forests and the drier, continental climate forests of central and eastern Anatolia. Central Anatolian deciduous forests: These forests of deciduous oaks and evergreen pines cover the plateau of central Anatolia. Central Anatolian steppe: These dry grasslands cover the drier valleys and surround the saline lakes of central Anatolia, and include halophytic (salt tolerant) plant communities. Eastern Anatolian deciduous forests: This ecoregion occupies the plateau of eastern Anatolia. The drier and more continental climate is beneficial for steppe-forests dominated by deciduous oaks, with areas of shrubland, montane forest, and valley forest. Anatolian conifer and deciduous mixed forests: These forests occupy the western, Mediterranean-climate portion of the Anatolian plateau. Pine forests and mixed pine and oak woodlands and shrublands are predominant. Aegean and Western Turkey sclerophyllous and mixed forests: These Mediterranean-climate forests occupy the coastal lowlands and valleys of western Anatolia bordering the Aegean Sea. The ecoregion has forests of Turkish pine (Pinus brutia), oak forests and woodlands, and maquis shrubland of Turkish pine and evergreen sclerophyllous trees and shrubs, including Olive (Olea europaea), Strawberry Tree (Arbutus unedo), Arbutus andrachne, Kermes Oak (Quercus coccifera), and Bay Laurel (Laurus nobilis). Southern Anatolian montane conifer and deciduous forests: These mountain forests occupy the Mediterranean-climate Taurus Mountains of southern Anatolia. Conifer forests are predominant, chiefly Anatolian black pine (Pinus nigra), Cedar of Lebanon (Cedrus libani), Taurus fir (Abies cilicica), and juniper (Juniperus foetidissima and J. excelsa). Broadleaf trees include oaks, hornbeam, and maples. Eastern Mediterranean conifer-sclerophyllous-broadleaf forests: This ecoregion occupies the coastal strip of southern Anatolia between the Taurus Mountains and the Mediterranean Sea. Plant communities include broadleaf sclerophyllous maquis shrublands, forests of Aleppo Pine (Pinus halepensis) and Turkish Pine (Pinus brutia), and dry oak (Quercus spp.) woodlands and steppes. == Demographics == Almost 80% of the people currently residing in Anatolia are Turks. Kurds constitute a major community in southeastern Anatolia, and are the largest ethnic minority. Abkhazians, Albanians, Arabs, Arameans, Armenians, Assyrians, Azerbaijanis, Bosnian Muslims, Circassians, Gagauz, Georgians, Serbs, Greeks, Hemshin, Jews, Laz, Levantines, Pomaks, Zazas and a number of other ethnic groups also live in Anatolia in smaller numbers. == Cuisine == Bamia is a traditional Anatolian-era stew dish prepared using lamb, okra and tomatoes as primary ingredients. == See also == == References == == Bibliography == == Further reading == Akat, Uücel, Neşe Özgünel, and Aynur Durukan. 1991.

### Instruction: retrieve labels for this: Apple Inc. is an American multinational technology company headquartered in Cupertino, California, that designs, develops, and sells consumer electronics, computer software, and online services. The company's hardware products include the iPhone smartphone, the iPad tablet computer, the Mac personal computer, the iPod portable media player, the Apple Watch smartwatch, the Apple TV digital media player, and the HomePod smart speaker. Apple's software includes the macOS and iOS operating systems, the iTunes media player, the Safari web browser, and the iLife and iWork creativity and productivity suites, as well as professional applications like Final Cut Pro, Logic Pro, and Xcode. Its online services include the iTunes Store, the iOS App Store and Mac App Store, Apple Music, and iCloud. Apple was founded by Steve Jobs, Steve Wozniak, and Ronald Wayne in April 1976 to develop and sell Wozniak's Apple I personal computer. It was incorporated as Apple Computer, Inc. in January 1977, and sales of its computers, including the Apple II, saw significant momentum and revenue growth for the company. Within a few years, Jobs and Wozniak had hired a staff of computer designers and had a production line. Apple went public in 1980 to instant financial success. Over the next few years, Apple shipped new computers featuring innovative graphical user interfaces, such as the original Macintosh in 1984, and Apple's marketing commercials for its products received widespread critical acclaim. However, the high price tag of its products and limited software titles caused problems, as did power struggles between executives at the company. In 1985, Wozniak stepped away from Apple and Jobs resigned entirely, bringing other Apple employees with him and creating his own company that same year—NeXT. As the market for personal computers increased, Apple's computers saw diminishing sales due to lower-priced products from competitors, in particular those offered with the Microsoft Windows operating system. More executive job shuffles happened at Apple until then-CEO Gil Amelio in 1997 decided to buy NeXT to bring Jobs back. Jobs regained leadership within the company and became the new CEO shortly after. He began a process to rebuild Apple's status, which included opening Apple's own retail stores in 2001, making numerous acquisitions of software companies to create a portfolio of software titles, and changing some of the hardware used in its computers. It again saw success and returned to profitability. In January 2007, Jobs announced that Apple Computer, Inc. would be renamed Apple Inc. to reflect its shifted focus toward consumer electronics. He also announced the iPhone, which saw critical acclaim and significant financial success. In August 2011, Jobs resigned as CEO due to health complications, and Tim Cook became the new CEO. Two months later, Jobs died, marking the end of an era for the company. Apple is the world's largest information technology company by revenue and the world's third-largest mobile phone manufacturer after Samsung and Huawei. In August 2018, Apple became the first public U.S. company to be valued at over US$1 trillion. The company employs 123,000 full-time employees and maintains 499 retail stores in 22 countries as of December 2017. It operates the iTunes Store, which is the world's largest music retailer. As of January 2016, more than one billion Apple products are actively in use worldwide. Apple's worldwide annual revenue totaled $229 billion for the 2017 fiscal year. The company enjoys a high level of brand loyalty and has been repeatedly ranked as the world's most valuable brand. However, it receives significant criticism regarding the labor practices of its contractors, its environmental and business practices, including anti-competitive behavior, as well as the origins of source materials. == History == === 1976–1984: Founding and incorporation === Apple Computer Company was founded on April 1, 1976, by Steve Jobs, Steve Wozniak and Ronald Wayne. The company's first product was the Apple I, a computer single-handedly designed and hand-built by Wozniak, and first shown to the public at the Homebrew Computer Club. Apple I was sold as a motherboard (with CPU, RAM, and basic textual-video chips), which was less than what is now considered a complete personal computer. The Apple I went on sale in July 1976 and was market-priced at $666.66 ($2,867 in 2017 dollars, adjusted for inflation).Apple Computer, Inc. was incorporated on January 3, 1977, without Wayne, who left and sold his share of the company back to Jobs and Wozniak for $800 only a couple weeks after co-founding Apple. Multimillionaire Mike Markkula provided essential business expertise and funding of $250,000 during the incorporation of Apple. During the first five years of operations revenues grew exponentially, doubling about every four months. Between September 1977 and September 1980, yearly sales grew from $775,000 to $118 million, an average annual growth rate of 533%.The Apple II, also invented by Wozniak, was introduced on April 16, 1977, at the first West Coast Computer Faire. It differed from its major rivals, the TRS-80 and Commodore PET, because of its character cell-based color graphics and open architecture. While early Apple II models used ordinary cassette tapes as storage devices, they were superseded by the introduction of a ​5 1⁄4-inch floppy disk drive and interface called the Disk II. The Apple II was chosen to be the desktop platform for the first "killer app" of the business world: VisiCalc, a spreadsheet program. VisiCalc created a business market for the Apple II and gave home users an additional reason to buy an Apple II: compatibility with the office. Before VisiCalc, Apple had been a distant third place competitor to Commodore and Tandy.By the end of the 1970s, Apple had a staff of computer designers and a production line. The company introduced the Apple III in May 1980 in an attempt to compete with IBM and Microsoft in the business and corporate computing market. Jobs and several Apple employees, including human–computer interface expert Jef Raskin, visited Xerox PARC in December 1979 to see the Xerox Alto. Xerox granted Apple engineers three days of access to the PARC facilities in return for the option to buy 100,000 shares (800,000 split-adjusted shares) of Apple at the pre-IPO price of $10 a share.Jobs was immediately convinced that all future computers would use a graphical user interface (GUI), and development of a GUI began for the Apple Lisa. In 1982, however, he was pushed from the Lisa team due to infighting. Jobs then took over Wozniak and Raskin's low-cost-computer project, the Macintosh. A race broke out between the Lisa team and the Macintosh team over which product would ship first. Lisa won the race in 1983 and became the first personal computer sold to the public with a GUI, but was a commercial failure due to its high price tag and limited software titles.On December 12, 1980, Apple went public at $22 per share, generating more capital than any IPO since Ford Motor Company in 1956, and immediately creating 300 millionaires. === 1984–1991: Success with Macintosh === In 1984, Apple launched the Macintosh, the first personal computer to be sold without a programming language. Its debut was signified by "1984", a $1.5 million television commercial directed by Ridley Scott that aired during the third quarter of Super Bowl XVIII on January 22, 1984. The commercial is now hailed as a watershed event for Apple's success and was called a "masterpiece" by CNN and one of the greatest commercials of all time by TV Guide.The Macintosh initially sold well, but follow-up sales were not strong due to its high price and limited range of software titles. The machine's fortunes changed with the introduction of the LaserWriter, the first PostScript laser printer to be sold at a reasonable price, and PageMaker, an early desktop publishing package. It has been suggested that the combination of these three products were responsible for the creation of the desktop publishing market. The Macintosh was particularly powerful in the desktop publishing market due to its advanced graphics capabilities, which had necessarily been built in to create the intuitive Macintosh GUI. In 1985, a power struggle developed between Jobs and CEO John Sculley, who had been hired two years earlier. The Apple board of directors instructed Sculley to "contain" Jobs and limit his ability to launch expensive forays into untested products. Rather than submit to Sculley's direction, Jobs attempted to oust him from his leadership role at Apple. Sculley found out that Jobs had been attempting to organize a coup and called a board meeting at which Apple's board of directors sided with Sculley and removed Jobs from his managerial duties. Jobs resigned from Apple and founded NeXT Inc. the same year. Wozniak also left Apple in 1985 to pursue other ventures, stating that the company had "been going in the wrong direction for the last five years". After Jobs' and Wozniak's departure, the Macintosh product line underwent a steady change of focus to higher price points, the so-called "high-right policy" named for the position on a chart of price vs. profits. Jobs had argued the company should produce products aimed at the consumer market and aimed for a $1000 price for the Macintosh, which they were unable to meet. Newer models selling at higher price points offered higher profit margin, and appeared to have no effect on total sales as power users snapped up every increase in power. Although some worried about pricing themselves out of the market, the high-right policy was in full force by the mid-1980s, notably due to Jean-Louis Gassée's mantra of "fifty-five or die", referring to the 55% profit margins of the Macintosh II.This policy began to backfire in the last years of the decade as new desktop publishing programs appeared on PC clones that offered some or much of the same functionality of the Macintosh but at far lower price points. The company lost its monopoly in this market and had already estranged many of its original consumer customer base who could no longer afford their high-priced products. The Christmas season of 1989 was the first in the company's history that saw declining sales, and led to a 20% drop in Apple's stock price. Gassée's objections were overruled, and he was forced from the company in 1990. Later that year, Apple introduced three lower cost models, the Macintosh Classic, Macintosh LC and Macintosh IIsi, all of which saw significant sales due to pent-up demand. In 1991, Apple introduced the PowerBook, replacing the "luggable" Macintosh Portable with a design that set the current shape for almost all modern laptops. The same year, Apple introduced System 7, a major upgrade to the operating system which added color to the interface and introduced new networking capabilities. It remained the architectural basis for the Classic Mac OS. The success of the PowerBook and other products brought increasing revenue. For some time, Apple was doing incredibly well, introducing fresh new products and generating increasing profits in the process. The magazine MacAddict named the period between 1989 and 1991 as the "first golden age" of the Macintosh.Apple believed the Apple II series was too expensive to produce and took away sales from the low-end Macintosh. In the 1990s, Apple released the Macintosh LC, and began efforts to promote that computer by advising developer technical support staff to recommend developing applications for Macintosh rather than Apple II, and authorizing salespersons to direct consumers towards Macintosh and away from Apple II. The Apple IIe was discontinued in 1993. === 1991–1997: Decline and restructuring === The success of Apple's lower-cost consumer models, especially the LC, also led to cannibalization of their higher priced machines. To address this, management introduced several new brands, selling largely identical machines at different price points aimed at different markets. These were the high-end Quadra, the mid-range Centris line, and the ill-fated Performa series. This led to significant market confusion, as customers did not understand the difference between models.Apple also experimented with a number of other unsuccessful consumer targeted products during the 1990s, including digital cameras, portable CD audio players, speakers, video consoles, the eWorld online service, and TV appliances. Enormous resources were also invested in the problem-plagued Newton division based on John Sculley's unrealistic market forecasts. Ultimately, none of these products helped and Apple's market share and stock prices continued to slide.Throughout this period, Microsoft continued to gain market share with Windows by focusing on delivering software to cheap commodity personal computers, while Apple was delivering a richly engineered but expensive experience. Apple relied on high profit margins and never developed a clear response; instead, they sued Microsoft for using a GUI similar to the Apple Lisa in Apple Computer, Inc. v. Microsoft Corp. The lawsuit dragged on for years before it was finally dismissed. At this time, a series of major product flops and missed deadlines sullied Apple's reputation, and Sculley was replaced as CEO by Michael Spindler. By the early 1990s, Apple was developing alternative platforms to the Macintosh, such as A/UX. The Macintosh platform itself was becoming outdated because it was not built for multitasking and because several important software routines were programmed directly into the hardware. In addition, Apple was facing competition from OS/2 and UNIX vendors such as Sun Microsystems. The Macintosh would need to be replaced by a new platform or reworked to run on more powerful hardware.In 1994, Apple allied with IBM and Motorola in the AIM alliance with the goal of creating a new computing platform (the PowerPC Reference Platform), which would use IBM and Motorola hardware coupled with Apple software. The AIM alliance hoped that PReP's performance and Apple's software would leave the PC far behind and thus counter Microsoft. The same year, Apple introduced the Power Macintosh, the first of many Apple computers to use Motorola's PowerPC processor.In 1996, Spindler was replaced by Gil Amelio as CEO. Amelio made numerous changes at Apple, including extensive layoffs and cut costs. After numerous failed attempts to improve Mac OS, first with the Taligent project and later with Copland and Gershwin, Amelio chose to purchase NeXT and its NeXTSTEP operating system and bring Steve Jobs back to Apple. === 1997–2007: Return to profitability === At the 1997 Macworld Expo, Jobs announced that Apple would join Microsoft to release new versions of Microsoft Office for the Macintosh, and that Microsoft had made a $150 million investment in non-voting Apple stock. On November 10, 1997, Apple introduced the Apple Online Store, which was tied to a new build-to-order manufacturing strategy.The NeXT deal was finalized on February 9, 1997, bringing Jobs back to Apple as an advisor. On July 9, 1997, Amelio was ousted by the board of directors after overseeing a three-year record-low stock price and crippling financial losses. Jobs acted as the interim CEO and began restructuring the company's product line; it was during this period that he identified the design talent of Jonathan Ive, and the pair worked collaboratively to rebuild Apple's status.On August 15, 1998, Apple introduced a new all-in-one computer reminiscent of the Macintosh 128K: the iMac. The iMac design team was led by Ive, who would later design the iPod and the iPhone. The iMac featured modern technology and a unique design, and sold almost 800,000 units in its first five months.During this period, Apple completed numerous acquisitions to create a portfolio of digital production software for both professionals and consumers. In 1998, Apple purchased Macromedia's Key Grip software project, signaling an expansion into the digital video editing market. The sale was an outcome of Macromedia's decision to solely focus upon web development software. The product, still unfinished at the time of the sale, was renamed "Final Cut Pro" when it was launched on the retail market in April 1999. The development of Key Grip also led to Apple's release of the consumer video-editing product iMovie in October 1999. Next, Apple successfully acquired the German company Astarte, which had developed DVD authoring technology, as well as Astarte's corresponding products and engineering team in April 2000. Astarte's digital tool DVDirector was subsequently transformed into the professional-oriented DVD Studio Pro software product. Apple then employed the same technology to create iDVD for the consumer market. In July 2001, Apple acquired Spruce Technologies, a PC DVD authoring platform, to incorporate their technology into Apple's expanding portfolio of digital video projects.In 2002, Apple purchased Nothing Real for their advanced digital compositing application Shake, as well as Emagic for the music productivity application Logic. The purchase of Emagic made Apple the first computer manufacturer to own a music software company. The acquisition was followed by the development of Apple's consumer-level GarageBand application. The release of iPhoto in the same year completed the iLife suite.Mac OS X, based on NeXT's OPENSTEP and BSD Unix, was released on March 24, 2001, after several years of development. Aimed at consumers and professionals alike, Mac OS X aimed to combine the stability, reliability, and security of Unix with the ease of use afforded by an overhauled user interface. To aid users in migrating from Mac OS 9, the new operating system allowed the use of OS 9 applications within Mac OS X via the Classic Environment.On May 19, 2001, Apple opened its first official eponymous retail stores in Virginia and California. On October 23 of the same year, Apple debuted the iPod portable digital audio player. The product, which was first sold on November 10, 2001, was phenomenally successful with over 100 million units sold within six years. In 2003, Apple's iTunes Store was introduced. The service offered online music downloads for $0.99 a song and integration with the iPod. The iTunes Store quickly became the market leader in online music services, with over five billion downloads by June 19, 2008. Two years later, the iTunes Store was the world's largest music retailer. At the Worldwide Developers Conference keynote address on June 6, 2005, Jobs announced that Apple would begin producing Intel-based Mac computers in 2006. On January 10, 2006, the new MacBook Pro and iMac became the first Apple computers to use Intel's Core Duo CPU. By August 7, 2006, Apple made the transition to Intel chips for the entire Mac product line—over one year sooner than announced. The Power Mac, iBook and PowerBook brands were retired during the transition; the Mac Pro, MacBook, and MacBook Pro became their respective successors. On April 29, 2009, The Wall Street Journal reported that Apple was building its own team of engineers to design microchips. Apple also introduced Boot Camp in 2006 to help users install Windows XP or Windows Vista on their Intel Macs alongside Mac OS X.Apple's success during this period was evident in its stock price. Between early 2003 and 2006, the price of Apple's stock increased more than tenfold, from around $6 per share (split-adjusted) to over $80. In January 2006, Apple's market cap surpassed that of Dell. Nine years prior, Dell's CEO Michael Dell had said that if he ran Apple he would "shut it down and give the money back to the shareholders." Although Apple's market share in computers had grown, it remained far behind it's competitor Microsoft Windows, accounting for about 8% of desktops and laptops in the US.Since 2001, Apple's design team has progressively abandoned the use of translucent colored plastics first used in the iMac G3. This design change began with the titanium-made PowerBook and was followed by the iBook's white polycarbonate structure and the flat-panel iMac. === 2007–2011: Success with mobile devices === During his keynote speech at the Macworld Expo on January 9, 2007, Jobs announced that Apple Computer, Inc. would thereafter be known as "Apple Inc.", because the company had shifted its emphasis from computers to consumer electronics. This event also saw the announcement of the iPhone and the Apple TV. The company sold 270,000 iPhone units during the first 30 hours of sales, and the device was called "a game changer for the industry". Apple would achieve widespread success with its iPhone, iPod Touch and iPad products, which introduced innovations in mobile phones, portable music players and personal computers respectively. Furthermore, by early 2007, 800,000 Final Cut Pro users were registered.In an article posted on Apple's website on February 6, 2007, Jobs wrote that Apple would be willing to sell music on the iTunes Store without digital rights management (DRM), thereby allowing tracks to be played on third-party players, if record labels would agree to drop the technology. On April 2, 2007, Apple and EMI jointly announced the removal of DRM technology from EMI's catalog in the iTunes Store, effective in May 2007. Other record labels eventually followed suit and Apple published a press release in January 2009 to announce the corresponding changes to the iTunes Store.In July 2008, Apple launched the App Store to sell third-party applications for the iPhone and iPod Touch. Within a month, the store sold 60 million applications and registered an average daily revenue of $1 million, with Jobs speculating in August 2008 that the App Store could become a billion-dollar business for Apple. By October 2008, Apple was the third-largest mobile handset supplier in the world due to the popularity of the iPhone.On December 16, 2008, Apple announced that 2009 would be the last year the corporation would attend the Macworld Expo, after more than 20 years of attendance, and that senior vice president of Worldwide Product Marketing Phil Schiller would deliver the 2009 keynote address in lieu of the expected Jobs. The official press release explained that Apple was "scaling back" on trade shows in general, including Macworld Tokyo and the Apple Expo in Paris, France, primarily because the enormous successes of the Apple Retail Stores and website had rendered trade shows a minor promotional channel.On January 14, 2009, Jobs announced in an internal memo that he would be taking a six-month medical leave of absence from Apple until the end of June 2009 and would spend the time focusing on his health. In the email, Jobs stated that "the curiosity over my personal health continues to be a distraction not only for me and my family, but everyone else at Apple as well", and explained that the break would allow the company "to focus on delivering extraordinary products". Despite Jobs's absence, Apple recorded its best non-holiday quarter (Q1 FY 2009) during the recession with revenue of $8.16 billion and profit of $1.21 billion. After years of speculation and multiple rumored "leaks", Apple unveiled a large screen, tablet-like media device known as the iPad on January 27, 2010. The iPad ran the same touch-based operating system as the iPhone, and many iPhone apps were compatible with the iPad. This gave the iPad a large app catalog on launch, despite very little development time before the release. Later that year on April 3, 2010, the iPad was launched in the US. It sold more than 300,000 units on its first day, and 500,000 by the end of the first week. In May of the same year, Apple's market cap exceeded that of competitor Microsoft for the first time since 1989.In June 2010, Apple released the iPhone 4, which introduced video calling, multitasking, and a new uninsulated stainless steel design that acted as the phone's antenna. Later that year, Apple again refreshed its iPod line of MP3 players by introducing a multi-touch iPod Nano, an iPod Touch with FaceTime, and an iPod Shuffle that brought back the buttons of earlier generations. Additionally, on October 20, Apple updated the MacBook Air laptop, iLife suite of applications, and unveiled Mac OS X Lion, the last version with the name Mac OS X.In October 2010, Apple shares hit an all-time high, eclipsing $300.On January 6, 2011, the company opened its Mac App Store, a digital software distribution platform similar to the iOS App Store.Alongside peer entities such as Atari and Cisco Systems, Apple was featured in the documentary Something Ventured, which premiered in 2011 and explored the three-decade era that led to the establishment and dominance of Silicon Valley.On January 17, 2011, Jobs announced in an internal Apple memo that he would take another medical leave of absence for an indefinite period to allow him to focus on his health. Chief Operating Officer Tim Cook assumed Jobs's day-to-day operations at Apple, although Jobs would still remain "involved in major strategic decisions". Apple became the most valuable consumer-facing brand in the world. In June 2011, Jobs surprisingly took the stage and unveiled iCloud, an online storage and syncing service for music, photos, files and software which replaced MobileMe, Apple's previous attempt at content syncing.This would be the last product launch Jobs would attend before his death. It has been argued that Apple has achieved such efficiency in its supply chain that the company operates as a monopsony (one buyer, many sellers) and can dictate terms to its suppliers. In July 2011, due to the American debt-ceiling crisis, Apple's financial reserves were briefly larger than those of the U.S. Government.On August 24, 2011, Jobs resigned his position as CEO of Apple. He was replaced by Cook and Jobs became Apple's chairman. Prior to this, Apple did not have a chairman and instead had two co-lead directors, Andrea Jung and Arthur D. Levinson, who continued with those titles until Levinson became chairman of the board in November. === 2011–present: Post-Steve Jobs era; Tim Cook leadership === On October 5, 2011, Steve Jobs died, marking the end of an era for Apple. The first major product announcement by Apple following Jobs's passing occurred on January 19, 2012, when Apple's Phil Schiller introduced iBooks Textbooks for iOS and iBook Author for Mac OS X in New York City. Jobs had stated in his biography that he wanted to reinvent the textbook industry and education.From 2011 to 2012, Apple released the iPhone 4S and iPhone 5, which featured improved cameras, an intelligent software assistant named Siri, and cloud-sourced data with iCloud; the third and fourth generation iPads, which featured Retina displays; and the iPad Mini, which featured a 7.9-inch screen in contrast to the iPad's 9.7-inch screen. These launches were successful, with the iPhone 5 (released September 21, 2012) becoming Apple's biggest iPhone launch with over two million pre-orders and sales of three million iPads in three days following the launch of the iPad Mini and fourth generation iPad (released November 3, 2012). Apple also released a third-generation 13-inch MacBook Pro with a Retina display and new iMac and Mac Mini computers.On August 20, 2012, Apple's rising stock price increased the company's market capitalization to a world-record $624 billion. This beat the non-inflation-adjusted record for market capitalization set by Microsoft in 1999. On August 24, 2012, a US jury ruled that Samsung should pay Apple $1.05 billion (£665m) in damages in an intellectual property lawsuit. Samsung appealed the damages award, which the Court reduced by $450 million. The Court further granted Samsung's request for a new trial. On November 10, 2012, Apple confirmed a global settlement that would dismiss all lawsuits between Apple and HTC up to that date, in favor of a ten-year license agreement for current and future patents between the two companies. It is predicted that Apple will make $280 million a year from this deal with HTC.A previously confidential email written by Jobs a year before his death was presented during the proceedings of the Apple Inc. v. Samsung Electronics Co. lawsuits and became publicly available in early April 2014. With a subject line that reads "Top 100 – A," the email was sent only to the company's 100 most senior employees and outlines Jobs's vision of Apple Inc.'s future under 10 subheadings. Notably, Jobs declares a "Holy War with Google" for 2011 and schedules a "new campus" for 2015.In March 2013, Apple filed a patent for an augmented reality (AR) system that can identify objects in a live video stream and present information corresponding to these objects through a computer-generated information layer overlaid on top of the real-world image. The company also made several high-profile hiring decisions in 2013. On July 2, 2013, Apple recruited Paul Deneve, Belgian President and CEO of Yves Saint Laurent as a vice president reporting directly to Tim Cook. A mid-October 2013 announcement revealed that Burberry executive Angela Ahrendts will commence as a senior vice president at Apple in mid-2014. Ahrendts oversaw Burberry's digital strategy for almost eight years and, during her tenure, sales increased to about US$3.2 billion and shares gained more than threefold.Alongside Google vice-president Vint Cerf and AT&T CEO Randall Stephenson, Cook attended a closed-door summit held by President Obama on August 8, 2013, in regard to government surveillance and the Internet in the wake of the Edward Snowden NSA incident. On February 4, 2014, Cook met with Abdullah Gül, the President of Turkey, in Ankara to discuss the company's involvement in the Fatih project.In the first quarter of 2014, Apple reported sales of 51 million iPhones and 26 million iPads, becoming all-time quarterly sales records. It also experienced a significant year-over-year increase in Mac sales. This was contrasted with a significant drop in iPod sales. In May 2014, the company confirmed its intent to acquire Dr. Dre and Jimmy Iovine's audio company Beats Electronics—producer of the "Beats by Dr. Dre" line of headphones and speaker products, and operator of the music streaming service Beats Music—for $3 billion, and to sell their products through Apple's retail outlets and resellers. Iovine felt that Beats had always "belonged" with Apple, as the company modeled itself after Apple's "unmatched ability to marry culture and technology." The acquisition was the largest purchase in Apple's history.Apple has been at the top of Interbrand's annual Best Global Brands report for 4 years in a row; 2013, 2014, 2015, and 2016, with a valuation of $178.1 billion.In January 2016, it was announced that one billion Apple devices are in active use worldwide.On May 12, 2016, Apple Inc., invested US$1 billion in Didi Chuxing, a Chinese competitor to Uber. The Information reported in October 2016 that Apple had taken a board seat in Didi Chuxing, a move that James Vincent of The Verge speculated could be a strategic company decision by Apple to get closer to the automobile industry, particularly Didi Chuxing's reported interest in self-driving cars.On June 6, 2016, Forbes released their list of companies ranked on revenue generation. In the trailing fiscal year, Apple appeared on the list as the top tech company. It ranked third, overall, with $233 billion in revenue. This represents a movement upward of two spots from the previous year's list.On April 6, 2017, Apple launched Clips, an app that allows iPad and iPhone users to make and edit videos. The app provides a way to produce short videos to share with other users on the Messages app, Instagram, Facebook and other social networks. Apple also introduced Live Titles for Clips that allows users to add live animated captions and titles using their voice.In May 2017, Apple refreshed two of its website designs. Its public relations "Apple Press Info" website was changed to an "Apple Newsroom" site, featuring a greater emphasis on imagery and therefore lower information density, and combines press releases, news items, and photos. Its "Apple Leadership" overview of company executives was also refreshed, adding a simpler layout with a prominent header image and two-column text fields. 9to5Mac noted the design similarities to several of Apple's redesigned apps in iOS 10, particularly its Apple Music and News software.In June 2017, Apple announced the HomePod, its smart speaker aimed to compete against Sonos and Amazon Echo. Towards the end of the year, TechCrunch reported that Apple was acquiring Shazam, a company specializing in music, TV, film and advertising recognition. The acquisition was confirmed a few days later, reportedly costing Apple $400 million, with media reports noting that the purchase looked like a move by Apple to get data and tools to bolster its Apple Music streaming service.On June 5, 2018, Apple deprecated OpenGL across all OSes and urges developers to use Metal as the alternative. == Products == === Mac === Macs currently in production: iMac: Consumer all-in-one desktop computer, introduced in 1998.

Several updated models have since been introduced, and the iPod brand is now the market leader in portable music players by a significant margin. More than 350 million units have shipped as of September 2012. Apple has partnered with Nike to offer the Nike+iPod Sports Kit, enabling runners to synchronize and monitor their runs with iTunes and the Nike+ website. In late July 2017, Apple discontinued its iPod Nano and iPod Shuffle models, leaving only the iPod Touch available for purchase. === iPhone === At the Macworld Conference & Expo in January 2007, Steve Jobs introduced the long-anticipated iPhone, a convergence of an Internet-enabled smartphone and iPod. The first-generation iPhone was released on June 29, 2007, for $499 (4 GB) and $599 (8 GB) with an AT&T contract. On February 5, 2008, it was updated to have 16 GB of memory, in addition to the 8 GB and 4 GB models. It combined a 2.5G quad band GSM and EDGE cellular phone with features found in handheld devices, running scaled-down versions of Apple's Mac OS X (dubbed iPhone OS, later renamed iOS), with various Mac OS X applications such as Safari and Mail. It also includes web-based and Dashboard apps such as Google Maps and Weather. The iPhone features a 3.5-inch (89 mm) touchscreen display, Bluetooth, and Wi-Fi (both "b" and "g").A second version, the iPhone 3G, was released on July 11, 2008, with a reduced price of $199 for the 8 GB version and $299 for the 16 GB version. This version added support for 3G networking and assisted GPS navigation. The flat silver back and large antenna square of the original model were eliminated in favor of a glossy, curved black or white back. Software capabilities were improved with the release of the App Store, which provided iPhone-compatible applications to download. On April 24, 2009, the App Store surpassed one billion downloads. On June 8, 2009, Apple announced the iPhone 3GS. It provided an incremental update to the device, including faster internal components, support for faster 3G speeds, video recording capability, and voice control. At the Worldwide Developers Conference (WWDC) on June 7, 2010, Apple announced the redesigned iPhone 4. It featured a 960 × 640 display, the Apple A4 processor, a gyroscope for enhanced gaming, a 5MP camera with LED flash, front-facing VGA camera and FaceTime video calling. Shortly after its release, reception issues were discovered by consumers, due to the stainless steel band around the edge of the device, which also serves as the phone's cellular signal and Wi-Fi antenna. The issue was corrected by a "Bumper Case" distributed by Apple for free to all owners for a few months. In June 2011, Apple overtook Nokia to become the world's biggest smartphone maker by volume. On October 4, 2011, Apple unveiled the iPhone 4S, which was first released on October 14, 2011. It features the Apple A5 processor and Siri voice assistant technology, the latter of which Apple had acquired in 2010. It also features an updated 8MP camera with new optics. Apple began a new accessibility feature, Made for iPhone Hearing Aids with the iPhone 4S. Made for iPhone Hearing Aids feature Live Listen, it can help the user hear a conversation in a noisy room or hear someone speaking across the room. Apple sold 4 million iPhone 4S phones in the first three days of availability.On September 12, 2012, Apple introduced the iPhone 5. It has a 4-inch display, 4G LTE connectivity, and the upgraded Apple A6 chip, among several other improvements. Two million iPhones were sold in the first twenty-four hours of pre-ordering and over five million handsets were sold in the first three days of its launch. Upon the launch of the iPhone 5S and iPhone 5C, Apple set a new record for first-weekend smartphone sales by selling over nine million devices in the first three days of its launch. The release of the iPhone 5S and 5C was the first time that Apple simultaneously launched two models.A patent filed in July 2013 revealed the development of a new iPhone battery system that uses location data in combination with data on the user's habits to moderate the handsets power settings accordingly. Apple is working towards a power management system that will provide features such as the ability of the iPhone to estimate the length of time a user will be away from a power source to modify energy usage and a detection function that adjusts the charging rate to best suit the type of power source that is being used.In a March 2014 interview, Apple designer Jonathan Ive used the iPhone as an example of Apple's ethos of creating high-quality, life-changing products. He explained that the phones are comparatively expensive due to the intensive effort that is used to make them: We don't take so long and make the way we make for fiscal reasons ... Quite the reverse. The body is made from a single piece of machined aluminium ... The whole thing is polished first to a mirror finish and then is very finely textured, except for the Apple logo. The chamfers [smoothed-off edges] are cut with diamond-tipped cutters. The cutters don't usually last very long, so we had to figure out a way of mass-manufacturing long-lasting ones. The camera cover is sapphire crystal. Look at the details around the SIM-card slot. It's extraordinary! On September 9, 2014, Apple introduced the iPhone 6, alongside the iPhone 6 Plus that both have screen sizes over 4-inches. One year later, Apple introduced the iPhone 6S, and iPhone 6S Plus, which introduced a new technology called 3D Touch, including an increase of the rear camera to 12 MP, and the FaceTime camera to 5 MP. On March 21, 2016, Apple introduced the iPhone SE that has a 4-inch screen size last used with the 5S and has nearly the same internal hardware as the 6S.In July 2016, Apple announced that one billion iPhones had been sold.On September 7, 2016, Apple introduced the iPhone 7 and the iPhone 7 Plus, which feature improved system and graphics performance, add water resistance, a new rear dual-camera system on the 7 Plus model, and, controversially, remove the 3.5 mm headphone jack. On September 12, 2017, Apple introduced the iPhone 8 and iPhone 8 Plus, standing as evolutionary updates to its previous phones with a faster processor, improved display technology, upgraded camera systems and wireless charging. The company also announced iPhone X, which radically changes the hardware of the iPhone lineup, removing the home button in favor of facial recognition technology and featuring a near bezel-less design along with wireless charging. === iPad === On January 27, 2010, Apple introduced their much-anticipated media tablet, the iPad. It offers multi-touch interaction with multimedia formats including newspapers, e-books, photos, videos, music, word processing documents, video games, and most existing iPhone apps using a 9.7-inch screen. It also includes a mobile version of Safari for web browsing, as well as access to the App Store, iTunes Library, iBookstore, Contacts, and Notes. Content is downloadable via Wi-Fi and optional 3G service or synced through the user's computer. AT&T was initially the sole U.S. provider of 3G wireless access for the iPad.On March 2, 2011, Apple introduced the iPad 2, which had a faster processor and a camera on the front and back. It also added support for optional 3G service provided by Verizon in addition to AT&T. The availability of the iPad 2 was initially limited as a result of a devastating earthquake and tsunami in Japan in March 2011.The third-generation iPad was released on March 7, 2012, and marketed as "the new iPad". It added LTE service from AT&T or Verizon, an upgraded A5X processor, and Retina display. The dimensions and form factor remained relatively unchanged, with the new iPad being a fraction thicker and heavier than the previous version and featuring minor positioning changes.On October 23, 2012, Apple's fourth-generation iPad came out, marketed as the "iPad with Retina display". It added the upgraded A6X processor and replaced the traditional 30-pin dock connector with the all-digital Lightning connector. The iPad Mini was also introduced. It featured a reduced 7.9-inch display and much of the same internal specifications as the iPad 2.On October 22, 2013, Apple introduced the iPad Air and the iPad Mini with Retina Display, both featuring a new 64-bit Apple A7 processor.The iPad Air 2 was unveiled on October 16, 2014. It added better graphics and central processing and a camera burst mode as well as minor updates. The iPad Mini 3 was unveiled at the same time.Since its launch, iPad users have downloaded over three billion apps. The total number of App Store downloads, as of June 2015, is over 100 billion.On September 9, 2015, Apple announced the iPad Pro, an iPad with a 12.9-inch display that supports two new accessories, the Smart Keyboard and Apple Pencil. An updated IPad Mini 4 was announced at the same time. A 9.7-inch iPad Pro was announced on March 21, 2016. On June 5, 2017, Apple announced a new iPad Pro with a 10.5-inch display to replace the 9.7 inch model and an updated 12.9-inch model. === Apple Watch === The original Apple Watch smartwatch was announced by Tim Cook on September 9, 2014, being introduced as a product with health and fitness-tracking. It was released on April 24, 2015.The second generation of Apple Watch, Apple Watch Series 2, was released in September 2016, featuring greater water resistance, a faster processor, and brighter display.On September 12, 2017, Apple introduced Apple Watch Series 3 featuring LTE cellular connectivity, giving the wearable independence from an iPhone except for the setup process. === Apple TV === At the 2007 Macworld conference, Jobs demonstrated the Apple TV (previously known as the iTV), a set-top video device intended to bridge the sale of content from iTunes with high-definition televisions. The device links up to a user's TV and syncs, either via Wi-Fi or a wired network, with one computer's iTunes library and streams content from an additional four. The Apple TV originally incorporated a 40 GB hard drive for storage, included outputs for HDMI and component video, and played video at a maximum resolution of 720p. On May 30, 2007, a 160 GB hard disk drive was released alongside the existing 40 GB model. A software update released on January 15, 2008, allowed media to be purchased directly from the Apple TV.In September 2009, Apple discontinued the original 40 GB Apple TV and now continues to produce and sell the 160 GB Apple TV. On September 1, 2010, Apple released a completely redesigned Apple TV. The new device is 1/4 the size, runs quieter, and replaces the need for a hard drive with media streaming from any iTunes library on the network along with 8 GB of flash memory to cache media downloaded. Like the iPad and the iPhone, Apple TV runs on an A4 processor. The memory included in the device is half of that in the iPhone 4 at 256 MB; the same as the iPad, iPhone 3GS, third and fourth-generation iPod Touch.It has HDMI out as the only video output source. Features include access to the iTunes Store to rent movies and TV shows (purchasing has been discontinued), streaming from internet video sources, including YouTube and Netflix, and media streaming from an iTunes library. Apple also reduced the price of the device to $99. A third generation of the device was introduced at an Apple event on March 7, 2012, with new features such as higher resolution (1080p) and a new user interface. At the September 9, 2015, event, Apple unveiled an overhauled Apple TV, which now runs a variant of macOS, called tvOS, and contains 32GB or 64 GB of NAND Flash to store games, programs, and to cache the current media playing. The release also coincided with the opening of a separate Apple TV App Store and a new Siri Remote with a glass touchpad, gyroscope, and microphone. At the September 12, 2017 event, Apple released a new 4K Apple TV with the same form factor as the 4th Generation model. The 4K model is powered by the A10X SoC designed in-house that also powers their second-generation iPad Pro. The 4K model also has support for high dynamic range. === HomePod === Apple's first smart speaker, the HomePod was released on February 9, 2018 after being delayed from its initial December 2017 release. It also features 7 tweeters in the base, a four-inch woofer in the top, and six microphones for voice control and acoustic optimization === Software === Apple develops its own operating systems to run on its devices, including macOS for Mac personal computers, iOS for its iPhone, iPad and iPod Touch smartphones and tablets, watchOS for its Apple Watch smartwatches, and tvOS for its Apple TV digital media player.For iOS and macOS, Apple also develops its own software titles, including Pages for writing, Numbers for spreadsheets, and Keynote for presentations, as part of its iWork productivity suite. For macOS, it also offers iMovie and Final Cut Pro X for video editing, and GarageBand and Logic Pro X for music creation.Apple's range of server software includes the operating system macOS Server; Apple Remote Desktop, a remote systems management application; and Xsan, a storage area network file system.Apple also offers online services with iCloud, which provides cloud storage and synchronization for a wide range of user data, including documents, photos, music, device backups, and application data, and Apple Music, its music and video streaming service. === Electric vehicles === According to the Sydney Morning Herald, Apple wants to start producing an electric car with autonomous driving as soon as 2020. Apple has made efforts to recruit battery development engineers and other electric automobile engineers from A123 Systems, LG Chem, Samsung Electronics, Panasonic, Toshiba, Johnson Controls and Tesla Motors. === Apple Energy === Apple Energy, LLC is a wholly owned subsidiary of Apple Inc. that sells solar energy. As of June 6, 2016, Apple's solar farms in California and Nevada have been declared to provide 217.9 megawatts of solar generation capacity. In addition to the company's solar energy production, Apple has received regulatory approval to construct a landfill gas energy plant in North Carolina. Apple will use the methane emissions to generate electricity. Apple's North Carolina data center is already powered entirely with energy from renewable sources. == Corporate identity == === Logo === According to Steve Jobs, the company's name was inspired by his visit to an apple farm while on a fruitarian diet. Jobs thought the name "Apple" was "fun, spirited and not intimidating".Apple's first logo, designed by Ron Wayne, depicts Sir Isaac Newton sitting under an apple tree. It was almost immediately replaced by Rob Janoff's "rainbow Apple", the now-familiar rainbow-colored silhouette of an apple with a bite taken out of it. Janoff presented Jobs with several different monochromatic themes for the "bitten" logo, and Jobs immediately took a liking to it. However, Jobs insisted that the logo be colorized to humanize the company. The logo was designed with a bite so that it would not be confused with a cherry. The colored stripes were conceived to make the logo more accessible, and to represent the fact the Apple II could generate graphics in color. This logo is often erroneously referred to as a tribute to Alan Turing, with the bite mark a reference to his method of suicide. Both Janoff and Apple deny any homage to Turing in the design of the logo.On August 27, 1999 (the year following the introduction of the iMac G3), Apple officially dropped the rainbow scheme and began to use monochromatic logos nearly identical in shape to the previous rainbow incarnation. An Aqua-themed version of the monochrome logo was used from 1998 to 2003, and a glass-themed version was used from 2007 to 2013.Steve Jobs and Steve Wozniak were Beatles fans, but Apple Inc. had name and logo trademark issues with Apple Corps Ltd., a multimedia company started by the Beatles in 1967. This resulted in a series of lawsuits and tension between the two companies. These issues ended with the settling of their lawsuit in 2007. === Advertising === Apple's first slogan, "Byte into an Apple", was coined in the late 1970s. From 1997 to 2002, the slogan "Think Different" was used in advertising campaigns, and is still closely associated with Apple. Apple also has slogans for specific product lines — for example, "iThink, therefore iMac" was used in 1998 to promote the iMac, and "Say hello to iPhone" has been used in iPhone advertisements. "Hello" was also used to introduce the original Macintosh, Newton, iMac ("hello (again)"), and iPod.From the introduction of the Macintosh in 1984, with the 1984 Super Bowl commercial to the more modern 'Get a Mac' adverts, Apple has been recognized for its efforts towards effective advertising and marketing for its products. However, claims made by later campaigns were criticized, particularly the 2005 Power Mac ads. Apple's product commercials gained a lot of attention as a result of their eye-popping graphics and catchy tunes. Musicians who benefited from an improved profile as a result of their songs being included on Apple commercials include Canadian singer Feist with the song "1234" and Yael Naïm with the song "New Soul".Apple owns a YouTube channel where they release advertisements, tips, and introductions for their devices. === Brand loyalty === Apple customers gained a reputation for devotion and loyalty early in the company's history. BYTE in 1984 stated that There are two kinds of people in the world: people who say Apple isn't just a company, it's a cause; and people who say Apple isn't a cause, it's just a company. Both groups are right. Nature has suspended the principle of noncontradiction where Apple is concerned. Apple is more than just a company because its founding has some of the qualities of myth ... Apple is two guys in a garage undertaking the mission of bringing computing power, once reserved for big corporations, to ordinary individuals with ordinary budgets. The company's growth from two guys to a billion-dollar corporation exemplifies the American Dream. Even as a large corporation, Apple plays David to IBM's Goliath, and thus has the sympathetic role in that myth. Apple evangelists were actively engaged by the company at one time, but this was after the phenomenon had already been firmly established. Apple evangelist Guy Kawasaki has called the brand fanaticism "something that was stumbled upon," while Ive explained in 2014 that "People have an incredibly personal relationship" with Apple's products. Apple Store openings and new product releases can draw crowds of hundreds, with some waiting in line as much as a day before the opening. The opening of New York City's Fifth Avenue "Cube" store in 2006 became the setting of a marriage proposal, and had visitors from Europe who flew in for the event. In June 2017, a newlywed couple took their wedding photos inside the then-recently opened Orchard Road Apple Store in Singapore. The high level of brand loyalty has been criticized and ridiculed, applying the epithet "Apple fanboy" and mocking the lengthy lines before a product launch. An internal memo leaked in 2015 suggested the company planned to discourage long lines and direct customers to purchase its products on its website.Fortune magazine named Apple the most admired company in the United States in 2008, and in the world from 2008 to 2012. On September 30, 2013, Apple surpassed Coca-Cola to become the world's most valuable brand in the Omnicom Group's "Best Global Brands" report. Boston Consulting Group has ranked Apple as the world's most innovative brand every year since 2005.The New York Times in 1985 stated that "Apple above all else is a marketing company". John Sculley agreed, telling The Guardian newspaper in 1997 that "People talk about technology, but Apple was a marketing company. It was the marketing company of the decade." Research in 2002 by NetRatings indicate that the average Apple consumer was usually more affluent and better educated than other PC company consumers. The research indicated that this correlation could stem from the fact that on average Apple Inc. products were more expensive than other PC products.In response to a query about the devotion of loyal Apple consumers, Jonathan Ive responded: What people are responding to is much bigger than the object. They are responding to something rare—a group of people who do more than simply make something work, they make the very best products they possibly can. It's a demonstration against thoughtlessness and carelessness. === Home page === The Apple website home page has been used to commemorate, or pay tribute to, milestones and events outside of Apple's product offerings: 2018: Martin Luther King Jr. 2017: Martin Luther King Jr. 2016: Muhammad Ali 2016: Bill Campbell (board member and friend) 2016: Martin Luther King Jr. 2014: Robin Williams 2015: Martin Luther King Jr. 2013: Nelson Mandela 2012: Steve Jobs 2011: Steve Jobs 2010: Jerome B. York (board member) 2007: Al Gore (board member in honor of his Nobel Peace Prize) 2005: Rosa Parks 2003: Gregory Hines 2001: George Harrison === Headquarters === Apple Inc.'s world corporate headquarters are located in the middle of Silicon Valley, at 1–6 Infinite Loop, Cupertino, California. This Apple campus has six buildings that total 850,000 square feet (79,000 m2) and was built in 1993 by Sobrato Development Cos.Apple has a satellite campus in neighboring Sunnyvale, California, where it houses a testing and research laboratory. AppleInsider published article in March 2014 claiming that Apple has a tucked away a top-secret facility where is developing the SG5 electric vehicle project codenamed "Titan" under the shell company name SixtyEight Research. In 2006, Apple announced its intention to build a second campus in Cupertino about 1 mile (1.6 km) east of the current campus and next to Interstate 280. The new campus building has been designed by Norman Foster. The Cupertino City Council approved the proposed "spaceship" design campus on October 15, 2013, after a 2011 presentation by Jobs detailing the architectural design of the new building and its environs. The new campus is planned to house up to 13,000 employees in one central, four-storied, circular building surrounded by extensive landscape. It will feature a café with room for 3,000 sitting people and parking underground as well as in a parking structure. The 2.8 million square foot facility will also include Jobs's original designs for a fitness center and a corporate auditorium. Apple has expanded its campuses in Austin, Texas concurrently with building Apple Park in Cupertino. The expansion consists of two locations, with one having 1.1 million square feet of workspace, and the other 216,000 square feet. At the biggest location, 6,000 employees work on technical support, manage Apple's network of suppliers to fulfill product shipments, aid in maintaining iTunes Store and App Store, handle economy, and continuously update Apple Maps with new data. At its smaller campus, 500 engineers work on next-generation processor chips to run in future Apple products.Apple's headquarters for Europe, the Middle East and Africa (EMEA) are located in Cork in the south of Ireland. The facility, which opened in 1980, was Apple's first location outside of the United States. Apple Sales International, which deals with all of Apple's international sales outside of the USA, is located at Apple's campus in Cork along with Apple Distribution International, which similarly deals with Apple's international distribution network. On April 20, 2012, Apple added 500 new jobs at its European headquarters, increasing the total workforce from around 2,800 to 3,300 employees. The company will build a new office block on its Hollyhill Campus to accommodate the additional staff. Its United Kingdom headquarters is at Stockley Park on the outskirts of London.In February 2015, Apple opened their new 180,000-square-foot headquarters in Herzliya, Israel, which will accommodate approximately 800 employees. This opening was Apple's third office located within Israel; the first, also in Herzliya, was obtained as part of the Anobit acquisition, and the other is a research center in Haifa.In December 2015, Apple bought the 70,000-square-foot manufacturing facility in North San Jose previously used by Maxim Integrated, in an $18.2 million deal. === Stores === The first Apple Stores were originally opened as two locations in May 2001 by then-CEO Steve Jobs, after years of attempting but failing store-within-a-store concepts. Seeing a need for improved retail presentation of the company's products, he began an effort in 1997 to revamp the retail program to get an improved relationship to consumers, and hired Ron Johnson in 2000. Jobs relaunched Apple's online store in 1997, and opened the first two physical stores in 2001. Despite initial media speculation that Apple would fail, its stores were highly successful, bypassing the sales numbers of competing nearby stores and within three years reached US$1 billion in annual sales, becoming the fastest retailer in history to do so. Over the years, Apple has expanded the number of retail locations and its geographical coverage, with 499 stores across 22 countries worldwide as of December 2017. Strong product sales have placed Apple among the top-tier retail stores, with sales over $16 billion globally in 2011.In May 2016, Angela Ahrendts, Apple's current Senior Vice President of Retail, unveiled a significantly redesigned Apple Store in Union Square, San Francisco, featuring large glass doors for the entry, open spaces, and rebranded rooms. In addition to purchasing products, consumers can get advice and help from "Creative Pros" – individuals with specialized knowledge of creative arts; get product support in a tree-lined Genius Grove; and attend sessions, conferences and community events, with Ahrendts commenting that the goal is to make Apple Stores into "town squares", a place where people naturally meet up and spend time. The new design will be applied to all Apple Stores worldwide, a process that has seen stores temporarily relocate or close.Many Apple Stores are located inside shopping malls, but Apple has built several stand-alone "flagship" stores in high-profile locations. It has been granted design patents and received architectural awards for its stores' designs and construction, specifically for its use of glass staircases and cubes. The success of Apple Stores have had significant influence over other consumer electronics retailers, who have lost traffic, control and profits due to a perceived higher quality of service and products at Apple Stores. Apple's notable brand loyalty among consumers causes long lines of hundreds of people at new Apple Store openings or product releases. Due to the popularity of the brand, Apple receives a large number of job applications, many of which come from young workers. Although Apple Store employees receive above-average pay, are offered money toward education and health care, and receive product discounts, there are limited or no paths of career advancement. A May 2016 report with an anonymous retail employee highlighted a hostile work environment with harassment from customers, intense internal criticism, and a lack of significant bonuses for securing major business contracts. Apple stores == Corporate affairs == === Corporate culture === Apple was one of several highly successful companies founded in the 1970s that bucked the traditional notions of corporate culture. Jobs often walked around the office barefoot even after Apple became a Fortune 500 company. By the time of the "1984" television commercial, Apple's informal culture had become a key trait that differentiated it from its competitors. According to a 2011 report in Fortune, this has resulted in a corporate culture more akin to a startup rather than a multinational corporation.As the company has grown and been led by a series of differently opinionated chief executives, it has arguably lost some of its original character. Nonetheless, it has maintained a reputation for fostering individuality and excellence that reliably attracts talented workers, particularly after Jobs returned to the company. Numerous Apple employees have stated that projects without Jobs's involvement often took longer than projects with it.To recognize the best of its employees, Apple created the Apple Fellows program which awards individuals who make extraordinary technical or leadership contributions to personal computing while at the company. The Apple Fellowship has so far been awarded to individuals including Bill Atkinson, Steve Capps, Rod Holt, Alan Kay, Guy Kawasaki, Al Alcorn, Don Norman, Rich Page, and Steve Wozniak. At Apple, employees are specialists who are not exposed to functions outside their area of expertise. Jobs saw this as a means of having "best-in-class" employees in every role. For instance, Ron Johnson—Senior Vice President of Retail Operations until November 1, 2011—was responsible for site selection, in-store service, and store layout, yet had no control of the inventory in his stores (this was done by Cook, who had a background in supply-chain management). Apple is also known for strictly enforcing accountability. Each project has a "directly responsible individual," or "DRI" in Apple jargon. As an example, when iOS senior vice president Scott Forstall refused to sign Apple's official apology for numerous errors in the redesigned Maps app, he was forced to resign. Unlike other major U.S. companies Apple provides a relatively simple compensation policy for executives that does not include perks enjoyed by other CEOs like country club fees or private use of company aircraft. The company typically grants stock options to executives every other year.In 2015, Apple had 110,000 full-time employees. This increased to 116,000 full-time employees the next year, a notable hiring decrease, largely due to its first revenue decline. Apple does not specify how many of its employees work in retail, though its 2014 SEC filing put the number at approximately half of its employee base. In September 2017, Apple announced that it had over 123,000 full-time employees.Apple has a strong culture of corporate secrecy, and has an anti-leak Global Security team that recruits from the National Security Agency, the Federal Bureau of Investigation and the United States Secret Service.In December 2017, Glassdoor named Facebook the best place to work, according to reviews from anonymous employees, with Apple dropping to 48th place, having originally entered at rank 19 in 2009, peaking at rank 10 in 2012, and falling down the ranks in subsequent years. ==== Lack of innovation ==== An editorial article in The Verge in September 2016 by technology journalist Thomas Ricker explored some of the public's perceived lack of innovation at Apple in recent years, specifically stating that Samsung has "matched and even surpassed Apple in terms of smartphone industrial design" and citing the belief that Apple is incapable of producing another breakthrough moment in technology with its products. He goes on to write that the criticism focuses on individual pieces of hardware rather than the ecosystem as a whole, stating "Yes, iteration is boring. But it's also how Apple does business. [...] It enters a new market and then refines and refines and continues refining until it yields a success". He acknowledges that people are wishing for the "excitement of revolution", but argues that people want "the comfort that comes with harmony". Furthermore, he writes that "a device is only the starting point of an experience that will ultimately be ruled by the ecosystem in which it was spawned", referring to how decent hardware products can still fail without a proper ecosystem (specifically mentioning that Walkman didn't have an ecosystem to keep users from leaving once something better came along), but how Apple devices in different hardware segments are able to communicate and cooperate through the iCloud cloud service with features including Universal Clipboard (in which text copied on one device can be pasted on a different device) as well as inter-connected device functionality including Auto Unlock (in which an Apple Watch can unlock a Mac in close proximity). He argues that Apple's ecosystem is its greatest innovation.The Wall Street Journal reported in June 2017 that Apple's increased reliance on Siri, its virtual personal assistant, has raised questions about how much Apple can actually accomplish in terms of functionality. Whereas Google and Amazon make use of big data and analyze customer information to personalize results, Apple has a strong pro-privacy stance, intentionally not retaining user data. "Siri is a textbook of leading on something in tech and then losing an edge despite having all the money and the talent and sitting in Silicon Valley", Holger Mueller, a technology analyst, told the Journal. The report further claims that development on Siri has suffered due to team members and executives leaving the company for competitors, a lack of ambitious goals, and shifting strategies. Despite switching Siri's functions to machine learning and algorithms, which dramatically cut its error rate, the company reportedly still failed to anticipate the popularity of Amazon's Echo, which features the Alexa personal assistant. Improvements to Siri stalled, executives clashed, and there were disagreements over the restrictions imposed on third-party app interactions. While Apple acquired an England-based startup specializing in conversational assistants, Google's Assistant had already become capable of helping users select Wi-Fi networks by voice, and Siri was lagging in functionality.In December 2017, two articles from The Verge and ZDNet debated what had been a particularly devastating week for Apple's macOS and iOS software platforms. The former had experienced a severe security vulnerability, in which Macs running the then-latest macOS High Sierra software were vulnerable to a bug that let anyone gain administrator privileges by entering "root" as the username in system prompts, leaving the password field empty and twice clicking "unlock", gaining full access. The bug was publicly disclosed on Twitter, rather than through proper bug bounty programs. Apple released a security fix within a day and issued an apology, stating that "regrettably we stumbled" in regards to the security of the latest updates. After installing the security patch, however, file sharing was broken for users, with Apple releasing a support document with instructions to separately fix that issue. Despite its promise of "auditing our development processes to help prevent this from happening again", users who installed the security update while running the older 10.13.0 version of the High Sierra operating system rather than the then-newest 10.13.1 release experienced that the "root" security vulnerability was re-introduced, and persisted even after fully updating their systems. On iOS, a date bug caused iOS devices that received local app notifications at 12:15am on December 2, 2017 to repeatedly restart. Users were recommended to turn off notifications for their apps. Apple quickly released an update, done during the nighttime in Cupertino, California time and outside of their usual software release window, with one of the headlining features of the update needing to be delayed for a few days. The combined problems of the week on both macOS and iOS caused The Verge's Tom Warren to call it a "nightmare" for Apple's software engineers and described it as a significant lapse in Apple's ability to protect its more than 1 billion devices. ZDNet's Adrian Kingsley-Hughes wrote that "it's hard to not come away from the last week with the feeling that Apple is slipping". Kingsley-Hughes also concluded his piece by referencing an earlier article, in which he wrote that "As much as I don't want to bring up the tired old "Apple wouldn't have done this under Steve Jobs' watch" trope, a lot of what's happening at Apple lately is different from what the [sic] came to expect under Jobs. Not to say that things didn't go wrong under his watch, but product announcements and launches felt a lot tighter for sure, as did the overall quality of what Apple was releasing." He did, however, also acknowledge that such failures "may indeed have happened" with Jobs in charge, though returning to the previous praise for Jobs' quality, stating "it's almost guaranteed that given his personality that heads would have rolled, which limits future failures". === Manufacturing === The company's manufacturing, procurement, and logistics enable it to execute massive product launches without having to maintain large, profit-sapping inventories. In 2011, Apple's profit margins were 40 percent, compared with between 10 and 20 percent for most other hardware companies. Cook's catchphrase to describe his focus on the company's operational arm is: "Nobody wants to buy sour milk".During the Mac's early history Apple generally refused to adopt prevailing industry standards for hardware, instead creating their own. This trend was largely reversed in the late 1990s, beginning with Apple's adoption of the PCI bus in the 7500/8500/9500 Power Macs. Apple has since joined the industry standards groups to influence the future direction of technology standards such as USB, AGP, HyperTransport, Wi-Fi, NVMe, PCIe and others in its products. FireWire is an Apple-originated standard that was widely adopted across the industry after it was standardized as IEEE 1394 and is a legally mandated port in all Cable TV boxes in the United States.Apple has gradually expanded its efforts in getting its products into the Indian market. In July 2012, during a conference call with investors, CEO Tim Cook said that he "[loves] India", but that Apple saw larger opportunities outside the region. India's requirement that 30% of products sold be manufactured in the country was described as "really adds cost to getting product to market". In October 2013, Indian Apple executives unveiled a plan for selling devices through instalment plans and store-within-a-store concepts, in an effort to expand further into the market. The news followed Cook's acknowledgment of the country in July when sales results showed that iPhone sales in India grew 400% during the second quarter of 2013. In March 2016, The Times of India reported that Apple had sought permission from the Indian government to sell refurbished iPhones in the country. However, two months later, the application was rejected, citing official country policy. In May 2016, Apple opened an iOS app development center in Bangalore and a maps development office for 4,000 staff in Hyderabad. In February 2017, Apple once again requested permission to sell used iPhones in the country. The same month, Bloomberg reported that Apple was close to receiving permission to open its first retail store in the country. In March, The Wall Street Journal reported that Apple would begin manufacturing iPhone models in India "over the next two months", and in May, the Journal wrote that an Apple manufacturer had begun production of iPhone SE in the country, while Apple told CNBC that the manufacturing was for a "small number" of units. Reuters reported in December 2017, that Apple and the Indian government were clashing over planned increases to import taxes for components used in mobile phone production, with Apple having engaged in talks with government officials to try to delay the plans, but the Indian government sticking to its policies of no exemptions to its "Made in India" initiative. The import tax increases went into effect a few days later, with Apple being hurt the most out of all phone manufacturers, having nine of out ten phones imported into the country, whereas main smartphone competitor Samsung produces almost all of its devices locally.In May 2017, the company announced a $1 billion funding project for "advanced manufacturing" in the United States, and subsequently invested $200 million in Corning Inc., a manufacturer of toughened Gorilla Glass technology used in its iPhone devices. The following December, Apple's chief operating officer, Jeff Williams, told CNBC that the "$1 billion" amount was "absolutely not" the final limit on its spending, elaborating that "We're not thinking in terms of a fund limit. ... We're thinking about, where are the opportunities across the U.S. to help nurture companies that are making the advanced technology — and the advanced manufacturing that goes with that — that quite frankly is essential to our innovation". ==== Labor practices ==== The company advertised its products as being made in America until the late 1990s; however, as a result of outsourcing initiatives in the 2000s, almost all of its manufacturing is now handled abroad. According to a report by The New York Times, Apple insiders "believe the vast scale of overseas factories, as well as the flexibility, diligence and industrial skills of foreign workers, have so outpaced their American counterparts that "Made in the U.S.A." is no longer a viable option for most Apple products".In 2006, the Mail on Sunday reported on the working conditions of the Chinese factories where contract manufacturers Foxconn and Inventec produced the iPod. The article stated that one complex of factories that assembled the iPod and other items had over 200,000 workers living and working within it. Employees regularly worked more than 60 hours per week and made around $100 per month. A little over half of the workers' earnings was required to pay for rent and food from the company.Apple immediately launched an investigation after the 2006 media report, and worked with their manufacturers to ensure acceptable working conditions. In 2007, Apple started yearly audits of all its suppliers regarding worker's rights, slowly raising standards and pruning suppliers that did not comply. Yearly progress reports have been published since 2008. In 2011, Apple admitted that its suppliers' child labor practices in China had worsened.The Foxconn suicides occurred between January and November 2010, when 18 Foxconn (Chinese: 富士康) employees attempted suicide, resulting in 14 deaths—the company was the world's largest contract electronics manufacturer, for clients including Apple, at the time. The suicides drew media attention, and employment practices at Foxconn were investigated by Apple. Apple issued a public statement about the suicides, and company spokesperson Steven Dowling said: [Apple is] saddened and upset by the recent suicides at Foxconn ... A team from Apple is independently evaluating the steps they are taking to address these tragic events and we will continue our ongoing inspections of the facilities where our products are made. The statement was released after the results from the company's probe into its suppliers' labor practices were published in early 2010. Foxconn was not specifically named in the report, but Apple identified a series of serious labor violations of labor laws, including Apple's own rules, and some child labor existed in a number of factories. Apple committed to the implementation of changes following the suicides.Also in 2010, workers in China planned to sue iPhone contractors over poisoning by a cleaner used to clean LCD screens. One worker claimed that he and his coworkers had not been informed of possible occupational illnesses. After a high suicide rate in a Foxconn facility in China making iPads and iPhones, albeit a lower rate than that of China as a whole, workers were forced to sign a legally binding document guaranteeing that they would not kill themselves. Workers in factories producing Apple products have also been exposed to n-hexane, a neurotoxin that is a cheaper alternative than alcohol for cleaning the products.A 2014 BBC investigation found excessive hours and other problems persisted, despite Apple's promise to reform factory practice after the 2010 Foxconn suicides. The Pegatron factory was once again the subject of review, as reporters gained access to the working conditions inside through recruitment as employees. While the BBC maintained that the experiences of its reporters showed that labor violations were continuing since 2010, Apple publicly disagreed with the BBC and stated: "We are aware of no other company doing as much as Apple to ensure fair and safe working conditions".In December 2014, the Institute for Global Labour and Human Rights published a report which documented inhumane conditions for the 15,000 workers at a Zhen Ding Technology factory in Shenzhen, China, which serves as a major supplier of circuit boards for Apple's iPhone and iPad. According to the report, workers are pressured into 65-hour work weeks which leaves them so exhausted that they often sleep during lunch breaks. They are also made to reside in "primitive, dark and filthy dorms" where they sleep "on plywood, with six to ten workers in each crowded room." Omnipresent security personnel also routinely harass and beat the workers. === Environmental practices and initiatives === ==== Energy and resources ==== Following a Greenpeace protest, Apple released a statement on April 17, 2012, committing to ending its use of coal and shifting to 100% renewable clean energy. By 2013 Apple was using 100% renewable energy to power their data centers. Overall, 75% of the company's power came from clean renewable sources.In 2010, Climate Counts, a nonprofit organization dedicated to directing consumers toward the greenest companies, gave Apple a score of 52 points out of a possible 100, which puts Apple in their top category "Striding". This was an increase from May 2008, when Climate Counts only gave Apple 11 points out of 100, which placed the company last among electronics companies, at which time Climate Counts also labeled Apple with a "stuck icon", adding that Apple at the time was "a choice to avoid for the climate conscious consumer".In May 2015, Greenpeace evaluated the state of the Green Internet and commended Apple on their environmental practices saying, "Apple's commitment to renewable energy has helped set a new bar for the industry, illustrating in very concrete terms that a 100% renewable Internet is within its reach, and providing several models of intervention for other companies that want to build a sustainable Internet."As of 2016, Apple states that 100% of its U.S. operations run on renewable energy, 100% of Apple's data centers run on renewable energy and 93% of Apple's global operations run on renewable energy. However, the facilities are connected to the local grid which usually contains a mix of fossil and renewable sources, so Apple carbon offsets its electricity use. The Electronic Product Environmental Assessment Tool (EPEAT) allows consumers to see the effect a product has on the environment. Each product receives a Gold, Silver, or Bronze rank depending on its efficiency and sustainability. Every Apple tablet, notebook, desktop computer, and display that EPEAT ranks achieves a Gold rating, the highest possible. Although Apple's data centers recycle water 35 times, the increased activity in retail, corporate and data centers also increase the amount of water use to 573 million gallons in 2015.During an event on March 21, 2016, Apple provided a status update on its environmental initiative to be 100% renewable in all of its worldwide operations. Lisa P. Jackson, Apple's vice president of Environment, Policy and Social Initiatives who reports directly to CEO, Tim Cook, announced that as of March 2016, 93% of Apple's worldwide operations are powered with renewable energy. Also featured was the company's efforts to use sustainable paper in their product packaging; 99% of all paper used by Apple in the product packaging comes from post-consumer recycled paper or sustainably managed forests, as the company continues its move to all paper packaging for all of its products. Apple working in partnership with Conservation Fund, have preserved 36,000 acres of working forests in Maine and North Carolina. Another partnership announced is with the World Wildlife Fund to preserve up to 1,000,000 acres of forests in China. Featured was the company's installation of a 40 MW solar power plant in the Sichuan province of China that was tailor-made to coexist with the indigenous yaks that eat hay produced on the land, by raising the panels to be several feet off of the ground so the yaks and their feed would be unharmed grazing beneath the array. This installation alone compensates for more than all of the energy used in Apple's Stores and Offices in the whole of China, negating the company's energy carbon footprint in the country. In Singapore, Apple has worked with the Singaporean government to cover the rooftops of 800 buildings in the city-state with solar panels allowing Apple's Singapore operations to be run on 100% renewable energy. Liam was introduced to the world, an advanced robotic disassembler and sorter designed by Apple Engineers in California specifically for recycling outdated or broken iPhones. Reuses and recycles parts from traded in products.Apple announced on August 16, 2016, that Lens Technology, one of its major suppliers in China, has committed to power all its glass production for Apple with 100 percent renewable energy by 2018. The commitment is a large step in Apple's efforts to help manufacturers lower their carbon footprint in China. Apple also announced that all 14 of its final assembly sites in China are now compliant with UL's Zero Waste to Landfill validation. The standard, which started in January 2015, certifies that all manufacturing waste is reused, recycled, composted, or converted into energy (when necessary). Since the program began, nearly, 140,000 metric tons of waste have been diverted from landfills. ==== Toxins ==== Following further campaigns by Greenpeace, in 2008, Apple became the first electronics manufacturer to fully eliminate all polyvinyl chloride (PVC) and brominated flame retardants (BFRs) in its complete product line. In June 2007, Apple began replacing the cold cathode fluorescent lamp (CCFL) backlit LCD displays in its computers with mercury-free LED-backlit LCD displays and arsenic-free glass, starting with the upgraded MacBook Pro. Apple offers comprehensive and transparent information about the CO2e, emissions, materials, and electrical usage concerning every product they currently produce or have sold in the past (and which they have enough data needed to produce the report), in their portfolio on their homepage. Allowing consumers to make informed purchasing decisions on the products they offer for sale. In June 2009, Apple's iPhone 3GS was free of PVC, arsenic, and BFRs. All Apple products now have mercury-free LED-backlit LCD displays, arsenic-free glass, and non-PVC cables. All Apple products have EPEAT Gold status and beat the latest Energy Star guidelines in each product's respective regulatory category.In November 2011, Apple was featured in Greenpeace's Guide to Greener Electronics, which ranks electronics manufacturers on sustainability, climate and energy policy, and how "green" their products are. The company ranked fourth of fifteen electronics companies (moving up five places from the previous year) with a score of 4.6/10. Greenpeace praises Apple's sustainability, noting that the company exceeded its 70% global recycling goal in 2010. It continues to score well on the products rating with all Apple products now being free of PVC plastic and BFRs. However, the guide criticizes Apple on the Energy criteria for not seeking external verification of its greenhouse gas emissions data and for not setting out any targets to reduce emissions. In January 2012, Apple requested that its cable maker, Volex, begin producing halogen-free USB and power cables. ==== Green bonds ==== In February 2016, Apple issued a US$1.5 billion green bond (climate bond), the first ever of its kind by a U.S. tech company. The green bond proceeds are dedicated to the financing of environmental projects. === Finance === Apple is the world's largest information technology company by revenue, the world's largest technology company by total assets, and the world's second-largest mobile phone manufacturer after Samsung.In its fiscal year ending in September 2011, Apple Inc. reported a total of $108 billion in annual revenues—a significant increase from its 2010 revenues of $65 billion—and nearly $82 billion in cash reserves. On March 19, 2012, Apple announced plans for a $2.65-per-share dividend beginning in fourth quarter of 2012, per approval by their board of directors.The company's worldwide annual revenue in 2013 totaled $170 billion. In May 2013, Apple entered the top ten of the Fortune 500 list of companies for the first time, rising 11 places above its 2012 ranking to take the sixth position. As of 2016, Apple has around US$234 billion of cash and marketable securities, of which 90% is located outside the United States for tax purposes.Apple amassed 65% of all profits made by the eight largest worldwide smartphone manufacturers in quarter one of 2014, according to a report by Canaccord Genuity. In the first quarter of 2015, the company garnered 92% of all earnings.On April 30, 2017, The Wall Street Journal reported that Apple had cash reserves of $250 billion, officially confirmed by Apple as specifically $256.8 billion a few days later.As of August 3, 2018, Apple is the largest publicly traded corporation in the world by market capitalization. On August 2, 2018, Apple became the first publicly traded U.S. company to reach a $1 trillion market value. ==== Tax practices ==== Apple has created subsidiaries in low-tax places such as Ireland, the Netherlands, Luxembourg and the British Virgin Islands to cut the taxes it pays around the world. According to The New York Times, in the 1980s Apple was among the first tech companies to designate overseas salespeople in high-tax countries in a manner that allowed the company to sell on behalf of low-tax subsidiaries on other continents, sidestepping income taxes. In the late 1980s, Apple was a pioneer of an accounting technique known as the "Double Irish with a Dutch sandwich," which reduces taxes by routing profits through Irish subsidiaries and the Netherlands and then to the Caribbean.British Conservative Party Member of Parliament Charlie Elphicke published research on October 30, 2012, which showed that some multinational companies, including Apple Inc., were making billions of pounds of profit in the UK, but were paying an effective tax rate to the UK Treasury of only 3 percent, well below standard corporation tax. He followed this research by calling on the Chancellor of the Exchequer George Osborne to force these multinationals, which also included Google and The Coca-Cola Company, to state the effective rate of tax they pay on their UK revenues. Elphicke also said that government contracts should be withheld from multinationals who do not pay their fair share of UK tax.Apple Inc. claims to be the single largest taxpayer to the Department of the Treasury of the United States of America with an effective tax rate of approximately of 26% as of the Second Quarter of the Apple Fiscal Year 2016. In an interview with the German newspaper FAZ in October 2017, Tim Cook stated, that Apple is the biggest taxpayer worldwide.In 2015, Reuters reported that Apple had earnings abroad of $54.4 billion which were untaxed by the IRS of the United States. Under U.S. tax law governed by the IRC, corporations don't pay income tax on overseas profits unless the profits are repatriated into the United States and as such Apple argues that to benefit its shareholders it will leave it overseas until a repatriation holiday or comprehensive tax reform takes place in the United States.On 12 July 2016 the Central Statistics Office (Ireland) announced that 2015 Irish GDP had grown by 26.3%, and 2015 Irish GNP had grown by 18.7%. The figures attracted international scorn, and were labelled by Nobel-prize winning economist, Paul Krugman, as leprechaun economics. It was not until 2018 that Irish economists could definitively prove that the 2015 growth was due to Apple restructuring its controversial double Irish subsidiaries (Apple Sales International), which Apple converted into a new Irish capital allowances for intangible assets tax scheme (expires in January 2020). The affair required the Central Bank of Ireland to create a new measure of Irish economic growth, Modified GNI* to replace Irish GDP, given the distortion of Apple's tax schemes. Irish GDP is 143% of Irish Modified GNI*. On August 30, 2016, after a two-year investigation, the EU Competition Commissioner concluded Apple received "illegal State aid" from Ireland. The EU ordered Apple to pay 13 billion euros ($14.5 billion), plus interest, in unpaid Irishtaxes for 2004-2014. It is the largest tax fine in history. The Commission found that Apple had benefitted from a private Irish Revenue Commissioners tax ruling regarding its double Irish tax structure, Apple Sales International (ASI). Instead of using two companies for its double Irish structure, Apple was given a ruling to split ASI into two internal "branches". The Chancellor of Austria, Christian Kern, put this decision into perspective by stating that "every Viennese cafe, every sausage stand pays more tax in Austria than a multinational corporation".As of April 24, 2018, Apple agreed to start paying €13 billion in back taxes to the Irish government, the repayments will be held in an escrow account while Apple and the Irish government continue their appeals in EU courts. === Ownership === Apple Inc. is a joint-stock company registered with the SEC. As of 20 July 2018, it has 4,829,926,000 outstanding shares. These are mainly held by institutional investors and funds. 7.05% (348,468,032): The Vanguard Group, Inc. 6.47% (319,715,585): BlackRock Inc. 4.86% (240,300,000): Berkshire Hathaway, Inc. 4.22% (208,739,070): State Street Corporation 2.46% (121,724,426): FMR, LLC 2.19% (108,093,912): Vanguard Total Stock Market Index Fund 1.67% (82,373,427): Vanguard 500 Index Fund 1.47% (72,476,069): T. Rowe Price Associates Inc. 1.33% (65,684,289): Northern Trust Corporation 1.32% (65,251,364): SPDR S&P 500 ETF Trust 1.16% (57,205,596): Vanguard Institutional Index Fund-Institutional Index Fund 1.14% (56,447,158): Geode Capital Management, LLC 1.08% (53,301,694): Bank of New York Mellon Corporation 1.04% (51,621,255): JP Morgan Chase and Co. === Litigation === Apple has been a participant in various legal proceedings and claims since it began operation. In particular, Apple is known for and promotes itself as actively and aggressively enforcing its intellectual property interests. Some litigation examples include Apple v. Samsung, Apple v. Microsoft, Motorola Mobility v. Apple Inc., and Apple Corps v. Apple Computer. Apple has also had to defend itself against charges on numerous occasions of violating intellectual property rights. Most have been dismissed in the courts as shell companies known as patent trolls, with no evidence of actual use of patents in question. On December 21, 2016, Nokia announced that in the U.S. and Germany, it has filed a suit against Apple, claiming that the latter's products infringe on Nokia's patents. Most recently, in November 2017, the United States International Trade Commission announced an investigation into allegations of patent infringement in regards to Apple's remote desktop technology; Aqua Connect, a company that builds remote desktop software, has claimed that Apple infringed on two of its patents. === Privacy stance === Apple has a notable pro-privacy stance, actively making privacy-conscious features and settings part of its conferences, promotional campaigns, and public image. With its iOS 8 mobile operating system in 2014, the company started encryption all contents of iOS devices through users' passcodes, making it impossible for the company to provide customer data to law enforcement requests seeking such information. With the popularity rise of cloud storage solutions, Apple began a technique in 2016 to do deep learning scans for facial data in photos on the user's local device and encrypting the content before uploading it to Apple's iCloud storage system. It also introduced "differential privacy", a way to collect crowdsourced data from many users, while keeping individual users anonymous, in a system that Wired described as "trying to learn as much as possible about a group while learning as little as possible about any individual in it". Users are explicitly asked if they want to participate, and can actively opt-in or opt-out.That said, Apple aids law enforcement in criminal investigations by providing iCloud backups of users' devices, and the company's commitment to privacy has been questioned by its efforts to promote biometric authentication technology in its newer iPhone models, which don't have the same level of constitutional privacy as a passcode in the United States. === Charitable causes === Apple is a partner of (PRODUCT)RED, a fundraising campaign for AIDS charity. In November 2014, Apple arranged for all App Store revenue in a two-week period to go to the fundraiser, generating more than US$20 million, and in March 2017, it released an iPhone 7 with a red color finish.Apple contributes financially to fundraisers in times of natural disasters. In November 2012, it donated $2.5 million to the American Red Cross to aid relief efforts after Hurricane Sandy, and in 2017 it donated $5 million to relief efforts for both Hurricane Irma and Hurricane Harvey, as well as for the 2017 Central Mexico earthquake. The company has also used its iTunes platform to encourage donations, including, but not limited to, help the American Red Cross in the aftermath of the 2010 Haiti earthquake, followed by similar procedure in the aftermath of the 2011 Japan earthquake, Typhoon Haiyan in the Philippines in November 2013, and European migrant crisis in September 2015. Apple emphasizes that it does not incur any processing or other fees for iTunes donations, sending 100% of the payments directly to relief efforts, though it also acknowledges that the Red Cross does not receive any personal information on the users donating and that the payments may not be tax deductible.On April 14, 2016, Apple and the World Wide Fund for Nature (WWF) announced that they have engaged in a partnership to, "help protect life on our planet." Apple released a special page in the iTunes App Store, Apps for Earth. In the arrangement, Apple has committed that through April 24, WWF will receive 100% of the proceeds from the applications participating in the App Store via both the purchases of any paid apps and the In-App Purchases. Apple and WWF's Apps for Earth campaign raised more than $8 million in total proceeds to support WWF's conservation work. WWF announced the results at WWDC 2016 in San Francisco. == Criticism and controversies == Apple has been criticised for alleged unethical business practices such as anti-competitive behavior, rash litigation, and dubious tax tactics, production methods involving the use of sweatshop labor, customer service issues involving allegedly misleading warranties and insufficient data security, as well as its products' environmental footprint. Critics have claimed that Apple products combine stolen and/or purchased designs that Apple claims are its original creations. Additionally, it has been criticized for its alleged collaboration with the U.S. surveillance program PRISM. == See also == Apple media events Pixar EU illegal State aid case against Apple in Ireland Leprechaun economics Corporation tax in the Republic of Ireland == References == === Bibliography === == Further reading == == External links == Official website Apple Inc. companies grouped at OpenCorporates Geographic data related to Apple Inc. headquarters at OpenStreetMap ### Answer: <1976 establishments in California>, <Apple Inc.>, <Companies based in Cupertino, California>, <Companies established in 1976>, <Companies in the NASDAQ-100 Index>, <Computer companies of the United States>, <Computer hardware companies>, <Display technology companies>, <Electronics companies>, <Electronics companies of the United States>, <Home computer hardware companies>, <Mobile phone manufacturers>, <Multinational companies headquartered in the United States>, <Networking hardware companies>, <Portable audio player manufacturers>, <Publicly traded companies of the United States>, <Retail companies of the United States>, <Software companies based in the San Francisco Bay Area>, <Steve Jobs>, <Technology companies of the United States>, <Warrants issued in Hong Kong Stock Exchange>

### Instruction: retrieve labels for this: Aberdeenshire (Scots: Aiberdeenshire; Scottish Gaelic: Siorrachd Obar Dheathain) is one of the 32 council areas of Scotland. It takes its name from the old County of Aberdeen which had substantially different boundaries. Modern Aberdeenshire includes all of what was once Kincardineshire, as well as part of Banffshire. The old boundaries are still officially used for a few purposes, namely land registration and lieutenancy.Aberdeenshire Council is headquartered at Woodhill House, in Aberdeen, making it the only Scottish council whose headquarters are located outside its jurisdiction. Aberdeen itself forms a different council area (Aberdeen City). Aberdeenshire borders onto Angus and Perth and Kinross to the south, Highland and Moray to the west and Aberdeen City to the east. Traditionally, it has been economically dependent upon the primary sector (agriculture, fishing, and forestry) and related processing industries. Over the last 40 years, the development of the oil and gas industry and associated service sector has broadened Aberdeenshire's economic base, and contributed to a rapid population growth of some 50% since 1975. Its land represents 8% of Scotland's overall territory. It covers an area of 6,313 square kilometres (2,437 sq mi). == History == Aberdeenshire has a rich prehistoric and historic heritage. It is the locus of a large number of Neolithic and Bronze Age archaeological sites, including Longman Hill, Kempstone Hill, Catto Long Barrow and Cairn Lee. The area was settled in the Bronze Age by the Beaker culture, who arrived from the south around 2000–1800 BC. Stone circles and cairns were constructed predominantly in this era. In the Iron Age, hill forts were built. Around the 1st century AD, the Taexali people, who have left little history, were believed to have resided along the coast. The Picts were the next documented inhabitants of the area, and were no later than 800–900 AD. The Romans also were in the area during this period, as they left signs at Kintore. Christianity influenced the inhabitants early on, and there were Celtic monasteries at Old Deer and Monymusk.Since medieval times there have been a number of traditional paths that crossed the Mounth (a spur of mountainous land that extends from the higher inland range to the North Sea slightly north of Stonehaven) through present-day Aberdeenshire from the Scottish Lowlands to the Highlands. Some of the most well known and historically important trackways are the Causey Mounth and Elsick Mounth.Aberdeenshire played an important role in the fighting between the Scottish clans. Clan MacBeth and the Clan Canmore were two of the larger clans. Macbeth fell at Lumphanan in 1057. During the Anglo-Norman penetration, other families arrives such as House of Balliol, Clan Bruce, and Clan Cumming (Comyn). When the fighting amongst these newcomers resulted in the Scottish Wars of Independence, the English king Edward I traveled across the area twice, in 1296 and 1303. In 1307, Robert the Bruce was victorious near Inverurie. Along with his victory came new families, namely the Forbeses and the Gordons. These new families set the stage for the upcoming rivalries during the 14th and 15th centuries. This rivalry grew worse during and after the Protestant Reformation, when religion was another reason for conflict between the clans. The Gordon family adhered to Catholicism and the Forbes to Protestantism. Three universities were founded in the area prior to the 17th century, King's College in Old Aberdeen (1494), Marischal College in Aberdeen (1593), and the University of Fraserburgh (1597).After the end of the Revolution of 1688, an extended peaceful period was interrupted only by such fleeting events such as the Rising of 1715 and the Rising of 1745. The latter resulted in the end of the ascendancy of Episcopalianism and the feudal power of landowners. An era began of increased agricultural and industrial progress. During the 17th century, Aberdeenshire was the location of more fighting, centered on the Marquess of Montrose and the English Civil Wars. This period also saw increased wealth due to the increase in trade with Germany, Poland, and the Low Countries.The present council area is named after the historic county of Aberdeen, which had different boundaries and was abolished in 1975 under the Local Government (Scotland) Act 1973. It was replaced by Grampian Regional Council and five district councils: Banff and Buchan, Gordon, Kincardine and Deeside, Moray and the City of Aberdeen. The current Aberdeenshire consists of all of former Aberdeenshire, former Kincardineshire and the northeast portions of Banffshire. Local government functions were shared between the two levels. In 1996, under the Local Government etc (Scotland) Act 1994, the Banff and Buchan district, Gordon district and Kincardine and Deeside district were merged to form the present Aberdeenshire council area, with the other two districts becoming autonomous council areas. == Demographics == The population of the council area has risen over 50% since 1971 to approximately 261,800, representing 4.7% of Scotland's total. Aberdeenshire's population has increased by 9.1% since 2001, while Scotland's total population grew by 3.8%. The census lists a relatively high proportion of under 16s and slightly fewer people of working-age compared with the Scottish average.Aberdeenshire is one of the most homogeneous regions of the UK. In 2011 82.2% of residents identified as 'White Scottish', followed by 12.3% who are 'White British'. The largest ethnic minority group are Asian Scottish/British at 0.8%.The fourteen biggest settlements in Aberdeenshire (with 2011 population estimates) are: Peterhead (17,790) Fraserburgh (12,540) Inverurie (11,529) Westhill (11,220) Stonehaven (10,820) Ellon (9,910) Portlethen (7,327) Banchory (7,111) Turriff (4,804) Kintore (4,476) Huntly (4,461) Banff (3,931) Kemnay (3,830) Macduff (3,711) == Economy == Aberdeenshire's Gross Domestic Product (GDP) is estimated at £3,496m (2011), representing 5.2% of the Scottish total. Aberdeenshire's economy is closely linked to Aberdeen City's (GDP £7,906m) and in 2011 the region as a whole was calculated to contribute 16.8% of Scotland's GDP. Between 2012 and 2014 the combined Aberdeenshire and Aberdeen City economic forecast GDP growth rate is 6.8%, the highest growth rate of any local council area and above the Scottish rate of 4.8%.A significant proportion of Aberdeenshire's working residents commute to Aberdeen City for work, varying from 11.5% from Fraserburgh to 65% from Westhill. Average Gross Weekly Earnings (for full-time employees employed in work places in Aberdeenshire in 2011) are £570.60. This is lower than the Scottish average by £4.10 and a fall of 2.6% on the 2010 figure. The average gross weekly pay of people resident in Aberdeenshire is much higher, at £641.90, as many people commute out of Aberdeenshire, principally into Aberdeen City.Total employment (excluding farm data) in Aberdeenshire is estimated at 93,700 employees (Business Register and Employment Survey 2009). The majority of employees work within the service sector, predominantly in public administration, education and health. Almost 19% of employment is within the public sector. Aberdeenshire's economy remains closely linked to Aberdeen City's and the North Sea oil industry, with many employees in oil related jobs. The average monthly unemployment (claimant count) rate for Aberdeenshire in 2011 was 1.5%. This is lower than the average rates for Aberdeen City (2.3%), Scotland (4.2%) and the UK (3.8%). == Major Industries == Energy – There is significant energy related infrastructure, presence and expertise in Aberdeenshire. Peterhead is an important centre for the energy industry. Peterhead Port, which includes an extensive new quay with adjacent lay down area at Smith Quay, is a major support location for North Sea oil and gas exploration and production and the fast-growing global sub-sea sector. The Gas Terminal at St Fergus handles around 15% of the UK's natural gas requirements and the Peterhead power station is looking to host Britain's first carbon capture and storage power generation project. Fishing – Aberdeenshire is Scotland's foremost fishing area. In 2010, catches landed at Aberdeenshire's ports accounted for over half the total fish landings of Scotland, and almost 45% in the UK. Peterhead and Fraserburgh ports, alongside Aberdeen City, provide much of the employment in these sectors. Agriculture – Aberdeenshire is rich in arable land, with an estimated 9,000 people employed in the sector, and is best known for rearing livestock. Sheep are important in the higher ground. Tourism – this sector continues to grow, with a range of sights to be seen in the area. From the lively Cairngorm Mountain range to the bustling fishing ports on the North-east coast, Aberdeenshire samples a bit of everything. Aberdeenshire also has a rugged coastline, many sandy beaches and is a hot spot for tourist activity throughout the year. Almost 1.3 million tourists visited the region in 2011 – up 3% on the previous year. Whisky-distilling is still a practiced art in the area. == Governance and politics == The council has 70 councillors, elected in 19 multi-member wards by single transferable vote. The 2017 elections resulted in the following representation: The overall political composition of the council, following subsequent defections and by-elections, is as follows: The Council's Revenue Budget for 2012/13 totals approx £548 million. The Education, Learning and Leisure Service takes the largest share of budget (52.3%), followed by Housing and Social Work (24.3%), Infrastructure Services (15.9%), Joint Boards (such as Fire and Police) and Misc services (7.9%) and Trading Activities (0.4%). 21.5% of the revenue is raised locally through the Council Tax. Average Band D Council Tax is £1,141 (2012/13), no change on the previous year. The current chief executive of the Council is Jim Savege and the elected Council Co-Leaders are Richard Thomson and Alison Evison. Aberdeenshire also has a Provost, who is Councillor Hamish Vernal. The council has devolved power to six area committees: Banff and Buchan; Buchan; Formartine; Garioch; Marr; and Kincardine and Mearns. Each area committee takes decisions on local issues such as planning applications, and the split is meant to reflect the diverse circumstances of each area.

Numerous bays and estuaries are found along the seacoast of Aberdeenshire, including Banff Bay, Ythan Estuary, Stonehaven Bay and Thornyhive Bay. Aberdeenshire is in the rain shadow of the Grampians, therefore it is a generally dry climate, with portions of the coast, receiving 25 inches (64 cm) of moisture annually. Summers are mild and winters are typically cold in Aberdeenshire; Coastal temperatures are moderated by the North Sea such that coastal areas are typically cooler in the summer and warmer in winter than inland locations. Coastal areas are also subject to haar, or coastal fog. == Notable residents == John Skinner, (1721–1807) author, poet and ecclesiastic. Penned the famous verse, Tullochgorum.

They are often cited as progenitors of Mexican rap and hip-hop. == Background == The band traces its roots to the late-1980s hardcore scene in the Eastside of Los Angeles. They have played rapcore, with elements of punk, hip hop, rock, funk, jazz, indigenous music, and spoken word. Indigenous drums, flutes, and rattles are also commonly used in their music. Their lyrics often address the family and economic issues faced by the Chicano community, and they have been noted as activists for that community.As an example of the politically active and culturally important artists in Los Angeles in the 1990s, Aztlan Underground appeared on Culture Clash on Fox in 1993; and was part of Breaking Out, a concert on pay per view in 1998, The band was featured in the independent films Algun Dia and Frontierland in the 1990s, and on the upcoming Studio 49. The band has been mentioned or featured in various newspapers and magazines: the Vancouver Sun, New Times, BLU Magazine (an underground hip hop magazine), BAM Magazine, La Banda Elastica Magazine, and the Los Angeles Times calendar section. The band is also the subject of a chapter in the book It's Not About a Salary, by Brian Cross.Aztlan Underground remains active in the community, lending their voice to annual events such as The Farce of July, and the recent movement to recognize Indigenous People's Day in Los Angeles and beyond.In addition to forming their own label, Xicano Records and Film, Aztlan Underground were signed to a Basque record label in 1999 which enabled them to tour Spain extensively and perform in France and Portugal.

### Instruction: retrieve labels for this: Andy Warhol (; born Andrew Warhola; August 6, 1928 – February 22, 1987) was an American artist, director and producer who was a leading figure in the visual art movement known as pop art. His works explore the relationship between artistic expression, celebrity culture, and advertising that flourished by the 1960s, and span a variety of media, including painting, silkscreening, photography, film, and sculpture. Some of his best known works include the silkscreen paintings Campbell's Soup Cans (1962) and Marilyn Diptych (1962), the experimental film Chelsea Girls (1966), and the multimedia events known as the Exploding Plastic Inevitable (1966–67). Born and raised in Pittsburgh, Warhol initially pursued a successful career as a commercial illustrator. After exhibiting his work in several galleries in the late 1950s, he began to receive recognition as an influential and controversial artist. His New York studio, The Factory, became a well-known gathering place that brought together distinguished intellectuals, drag queens, playwrights, Bohemian street people, Hollywood celebrities, and wealthy patrons. He promoted a collection of personalities known as Warhol superstars, and is credited with coining the widely used expression "15 minutes of fame." In the late 1960s, he managed and produced the experimental rock band The Velvet Underground and founded Interview magazine. He authored numerous books, including The Philosophy of Andy Warhol and Popism: The Warhol Sixties. He lived openly as a gay man before the gay liberation movement. After gallbladder surgery, Warhol died of cardiac arrhythmia in February 1987 at the age of 58. Warhol has been the subject of numerous retrospective exhibitions, books, and feature and documentary films. The Andy Warhol Museum in his native city of Pittsburgh, which holds an extensive permanent collection of art and archives, is the largest museum in the United States dedicated to a single artist. Many of his creations are very collectible and highly valuable. The highest price ever paid for a Warhol painting is US$105 million for a 1963 canvas titled Silver Car Crash (Double Disaster); his works include some of the most expensive paintings ever sold. A 2009 article in The Economist described Warhol as the "bellwether of the art market". == Biography == === Early life and beginnings (1928–49) === Warhol was born on August 6, 1928, in Pittsburgh, Pennsylvania. He was the fourth child of Ondrej Warhola (Americanized as Andrew Warhola, Sr., 1889–1942) and Julia (née Zavacká, 1892–1972), whose first child was born in their homeland and died before their move to the U.S. His parents were working-class Lemko emigrants from Mikó (now called Miková), located in today's northeastern Slovakia, part of the former Austro-Hungarian Empire. Warhol's father emigrated to the United States in 1914, and his mother joined him in 1921, after the death of Warhol's grandparents. Warhol's father worked in a coal mine. The family lived at 55 Beelen Street and later at 3252 Dawson Street in the Oakland neighborhood of Pittsburgh. The family was Ruthenian Catholic and attended St. John Chrysostom Byzantine Catholic Church. Andy Warhol had two older brothers—Pavol (Paul), the oldest, was born before the family emigrated; Ján was born in Pittsburgh. Pavol's son, James Warhola, became a successful children's book illustrator. In third grade, Warhol had Sydenham's chorea (also known as St. Vitus' Dance), the nervous system disease that causes involuntary movements of the extremities, which is believed to be a complication of scarlet fever which causes skin pigmentation blotchiness. He became a hypochondriac, developing a fear of hospitals and doctors. Often bedridden as a child, he became an outcast at school and bonded with his mother. At times when he was confined to bed, he drew, listened to the radio and collected pictures of movie stars around his bed. Warhol later described this period as very important in the development of his personality, skill-set and preferences. When Warhol was 13, his father died in an accident.As a teenager, Warhol graduated from Schenley High School in 1945. Also as a teen, Warhol won a Scholastic Art and Writing Award. After graduating from high school, his intentions were to study art education at the University of Pittsburgh in the hope of becoming an art teacher, but his plans changed and he enrolled in the Carnegie Institute of Technology, now Carnegie Mellon University in Pittsburgh, where he studied commercial art. During his time there, Warhol joined the campus Modern Dance Club and Beaux Arts Society. He also served as art director of the student art magazine, Cano, illustrating a cover in 1948 and a full-page interior illustration in 1949. These are believed to be his first two published artworks. Warhol earned a Bachelor of Fine Arts in pictorial design in 1949. Later that year, he moved to New York City and began a career in magazine illustration and advertising. === 1950s === Warhol's early career was dedicated to commercial and advertising art, where his first commission had been to draw shoes for Glamour magazine in the late 1940s. In the 1950s, Warhol worked as a designer for shoe manufacturer Israel Miller. American photographer John Coplans recalled that nobody drew shoes the way Andy did. He somehow gave each shoe a temperament of its own, a sort of sly, Toulouse-Lautrec kind of sophistication, but the shape and the style came through accurately and the buckle was always in the right place. The kids in the apartment [which Andy shared in New York – note by Coplans] noticed that the vamps on Andy's shoe drawings kept getting longer and longer but [Israel] Miller didn't mind. Miller loved them. Warhol's "whimsical" ink drawings of shoe advertisements figured in some of his earliest showings at the Bodley Gallery in New York. Warhol was an early adopter of the silk screen printmaking process as a technique for making paintings. A young Warhol was taught silk screen printmaking techniques by Max Arthur Cohn at his graphic arts business in Manhattan. While working in the shoe industry, Warhol developed his "blotted line" technique, applying ink to paper and then blotting the ink while still wet, which was akin to a printmaking process on the most rudimentary scale. His use of tracing paper and ink allowed him to repeat the basic image and also to create endless variations on the theme, a method that prefigures his 1960s silk-screen canvas. In his book Popism: The Warhol Sixties, Warhol writes: "When you do something exactly wrong, you always turn up something."With the rapid expansion of the record industry, RCA Records hired Warhol, along with another freelance artist, Sid Maurer, to design album covers and promotional materials. === 1960s === He began exhibiting his work during the 1950s. He held exhibitions at the Hugo Gallery and the Bodley Gallery in New York City; in California, his first West Coast gallery exhibition was on July 9, 1962, in the Ferus Gallery of Los Angeles. The exhibition marked his West Coast debut of pop art. Andy Warhol's first New York solo pop art exhibition was hosted at Eleanor Ward's Stable Gallery November 6–24, 1962. The exhibit included the works Marilyn Diptych, 100 Soup Cans, 100 Coke Bottles, and 100 Dollar Bills. At the Stable Gallery exhibit, the artist met for the first time poet John Giorno who would star in Warhol's first film, Sleep, in 1963.It was during the 1960s that Warhol began to make paintings of iconic American objects such as dollar bills, mushroom clouds, electric chairs, Campbell's Soup Cans, Coca-Cola bottles, celebrities such as Marilyn Monroe, Elvis Presley, Marlon Brando, Troy Donahue, Muhammad Ali, and Elizabeth Taylor, as well as newspaper headlines or photographs of police dogs attacking African-American protesters during the Birmingham campaign in the civil rights movement. During these years, he founded his studio, "The Factory" and gathered about him a wide range of artists, writers, musicians, and underground celebrities. His work became popular and controversial. Warhol had this to say about Coca-Cola: What's great about this country is that America started the tradition where the richest consumers buy essentially the same things as the poorest. You can be watching TV and see Coca-Cola, and you know that the President drinks Coca-Cola, Liz Taylor drinks Coca-Cola, and just think, you can drink Coca-Cola, too. A Coke is a Coke and no amount of money can get you a better Coke than the one the bum on the corner is drinking. All the Cokes are the same and all the Cokes are good. Liz Taylor knows it, the President knows it, the bum knows it, and you know it. New York City's Museum of Modern Art hosted a Symposium on pop art in December 1962 during which artists such as Warhol were attacked for "capitulating" to consumerism. Critics were scandalized by Warhol's open embrace of market culture. This symposium set the tone for Warhol's reception. A pivotal event was the 1964 exhibit The American Supermarket, a show held in Paul Bianchini's Upper East Side gallery. The show was presented as a typical U.S. small supermarket environment, except that everything in it—from the produce, canned goods, meat, posters on the wall, etc.—was created by six prominent pop artists of the time, among them the controversial (and like-minded) Billy Apple, Mary Inman, and Robert Watts. Warhol's painting of a can of Campbell's soup cost $1,500 while each autographed can sold for $6. The exhibit was one of the first mass events that directly confronted the general public with both pop art and the perennial question of what art is. As an advertisement illustrator in the 1950s, Warhol used assistants to increase his productivity. Collaboration would remain a defining (and controversial) aspect of his working methods throughout his career; this was particularly true in the 1960s. One of the most important collaborators during this period was Gerard Malanga. Malanga assisted the artist with the production of silkscreens, films, sculpture, and other works at "The Factory", Warhol's aluminum foil-and-silver-paint-lined studio on 47th Street (later moved to Broadway). Other members of Warhol's Factory crowd included Freddie Herko, Ondine, Ronald Tavel, Mary Woronov, Billy Name, and Brigid Berlin (from whom he apparently got the idea to tape-record his phone conversations).During the 1960s, Warhol also groomed a retinue of bohemian and counterculture eccentrics upon whom he bestowed the designation "Superstars", including Nico, Joe Dallesandro, Edie Sedgwick, Viva, Ultra Violet, Holly Woodlawn, Jackie Curtis, and Candy Darling. These people all participated in the Factory films, and some—like Berlin—remained friends with Warhol until his death. Important figures in the New York underground art/cinema world, such as writer John Giorno and film-maker Jack Smith, also appear in Warhol films (many premiering at the New Andy Warhol Garrick Theatre and 55th Street Playhouse) of the 1960s, revealing Warhol's connections to a diverse range of artistic scenes during this time. Less well known was his support and collaboration with several teen-agers during this era, who would achieve prominence later in life including writer David Dalton, photographer Stephen Shore and artist Bibbe Hansen (mother of pop musician Beck). ==== Attempted murder (1968) ==== On June 3, 1968, radical feminist writer Valerie Solanas shot Warhol and Mario Amaya, art critic and curator, at Warhol's studio. Before the shooting, Solanas had been a marginal figure in the Factory scene. She authored in 1967 the S.C.U.M. Manifesto, a separatist feminist tract that advocated the elimination of men; and appeared in the 1968 Warhol film I, a Man. Earlier on the day of the attack, Solanas had been turned away from the Factory after asking for the return of a script she had given to Warhol. The script had apparently been misplaced.Amaya received only minor injuries and was released from the hospital later the same day. Warhol was seriously wounded by the attack and barely survived: surgeons opened his chest and massaged his heart to help stimulate its movement again. He suffered physical effects for the rest of his life, including being required to wear a surgical corset. The shooting had a profound effect on Warhol's life and art.Solanas was arrested the day after the assault, after turning herself in to police. By way of explanation, she said that Warhol "had too much control over my life." She was subsequently diagnosed with paranoid schizophrenia and eventually sentenced to three years under the control of the Department of Corrections. After the shooting, the Factory scene heavily increased security, and for many the "Factory 60s" ended.Warhol had this to say about the attack: "Before I was shot, I always thought that I was more half-there than all-there—I always suspected that I was watching TV instead of living life. People sometimes say that the way things happen in movies is unreal, but actually it's the way things happen in life that's unreal. The movies make emotions look so strong and real, whereas when things really do happen to you, it's like watching television—you don't feel anything. Right when I was being shot and ever since, I knew that I was watching television. The channels switch, but it's all television." === 1970s === Compared to the success and scandal of Warhol's work in the 1960s, the 1970s were a much quieter decade, as he became more entrepreneurial. According to Bob Colacello, Warhol devoted much of his time to rounding up new, rich patrons for portrait commissions—including Shah of Iran Mohammad Reza Pahlavi, his wife Empress Farah Pahlavi, his sister Princess Ashraf Pahlavi, Mick Jagger, Liza Minnelli, John Lennon, Diana Ross, and Brigitte Bardot. Warhol's famous portrait of Chinese Communist leader Mao Zedong was created in 1973. He also founded, with Gerard Malanga, Interview magazine, and published The Philosophy of Andy Warhol (1975). An idea expressed in the book: "Making money is art, and working is art and good business is the best art."Warhol socialized at various nightspots in New York City, including Max's Kansas City; and, later in the 1970s, Studio 54. He was generally regarded as quiet, shy, and a meticulous observer. Art critic Robert Hughes called him "the white mole of Union Square."In 1979, along with his longtime friend Stuart Pivar, Warhol founded the New York Academy of Art. === 1980s === Warhol had a re-emergence of critical and financial success in the 1980s, partially due to his affiliation and friendships with a number of prolific younger artists, who were dominating the "bull market" of 1980s New York art: Jean-Michel Basquiat, Julian Schnabel, David Salle and other so-called Neo-Expressionists, as well as members of the Transavantgarde movement in Europe, including Francesco Clemente and Enzo Cucchi. Before the 1984 Sarajevo Winter Olympics, he teamed with 15 other artists, including David Hockney and Cy Twombly, and contributed a Speed Skater print to the Art and Sport collection. The Speed Skater was used for the official Sarajevo Winter Olympics poster.By this time, graffiti artist Fab Five Freddy paid homage to Warhol when he painted an entire train with Campbell soup cans. This was instrumental in Freddy becoming involved in the underground NYC art scene and becoming an affiliate of Basquiat.By this period, Warhol was being criticized for becoming merely a "business artist". In 1979, reviewers disliked his exhibits of portraits of 1970s personalities and celebrities, calling them superficial, facile and commercial, with no depth or indication of the significance of the subjects. They also criticized his 1980 exhibit of 10 portraits at the Jewish Museum in Manhattan, entitled Jewish Geniuses, which Warhol—who was uninterested in Judaism and Jews—had described in his diary as "They're going to sell." In hindsight, however, some critics have come to view Warhol's superficiality and commerciality as "the most brilliant mirror of our times," contending that "Warhol had captured something irresistible about the zeitgeist of American culture in the 1970s."Warhol also had an appreciation for intense Hollywood glamour. He once said: "I love Los Angeles. I love Hollywood. They're so beautiful. Everything's plastic, but I love plastic. I want to be plastic."In 1984, Warhol immortalized the singer Prince by creating one of his final portraits, Orange Prince (1984), a commission from Vanity Fair to accompany an article to celebrate the success of Prince's album and movie entitled Purple Rain. Referencing the many celebrity portraits produced by Warhol across his career, Orange Prince (1984) was created using a similar composition to the Marilyn "Flavors" series from 1962, among some of Warhol's very first celebrity portraits. Prince is depicted in a pop color palette commonly used by Warhol, in bright orange with highlights of bright green and blue. The facial features and hair are screen-printed in black over the orange background.In the Andy Warhol Diaries, Warhol recorded how excited he was to see Prince and Billy Idol together at a party in the mid 1980s, and he compared them to the Hollywood movie stars of the 1950s and '60s who also inspired his portraits: "...seeing these two glamour boys, its like boys are the new Hollywood glamour girls, like Jean Harlow and Marilyn Monroe". == Works == === Paintings === By the beginning of the 1960s, pop art was an experimental form that several artists were independently adopting; some of these pioneers, such as Roy Lichtenstein, would later become synonymous with the movement. Warhol, who would become famous as the "Pope of Pop", turned to this new style, where popular subjects could be part of the artist's palette. His early paintings show images taken from cartoons and advertisements, hand-painted with paint drips. Marilyn Monroe was a pop art painting that Warhol had done and it was very popular. Those drips emulated the style of successful abstract expressionists (such as Willem de Kooning). Warhol's first pop art paintings were displayed in April 1961, serving as the backdrop for New York Department Store Bronwit Teller's window display. This was the same stage his Pop Art contemporaries Jasper Johns, James Rosenquist and Robert Rauschenberg had also once graced.It was the gallerist Muriel Latow who came up with the ideas for both the soup cans and Warhol's dollar paintings. On November 23, 1961, Warhol wrote Latow a check for $50 which, according to the 2009 Warhol biography, Pop, The Genius of Warhol, was payment for coming up with the idea of the soup cans as subject matter. For his first major exhibition, Warhol painted his famous cans of Campbell's soup, which he claimed to have had for lunch for most of his life. A 1964 Large Campbell’s Soup Can was sold in a 2007 Sotheby's auction to a South American collector for £5.1 million ($7.4 million).He loved celebrities, so he painted them as well. From these beginnings he developed his later style and subjects. Instead of working on a signature subject matter, as he started out to do, he worked more and more on a signature style, slowly eliminating the handmade from the artistic process. Warhol frequently used silk-screening; his later drawings were traced from slide projections. At the height of his fame as a painter, Warhol had several assistants who produced his silk-screen multiples, following his directions to make different versions and variations.In 1979, Warhol was commissioned by BMW to paint a Group-4 race version of the then "elite supercar" BMW M1 for the fourth installment in the BMW Art Car Project. It was reported at the time that, unlike the three artists before him, Warhol opted to paint directly onto the automobile himself instead of letting technicians transfer his scale-model design to the car. It was indicated that Warhol spent only a total of 23 minutes to paint the entire car.Warhol produced both comic and serious works; his subject could be a soup can or an electric chair. Warhol used the same techniques—silkscreens, reproduced serially, and often painted with bright colors—whether he painted celebrities, everyday objects, or images of suicide, car crashes, and disasters, as in the 1962–63 Death and Disaster series. The Death and Disaster paintings included Red Car Crash, Purple Jumping Man, and Orange Disaster. One of these paintings, the diptych Silver Car Crash, became the highest priced work of his when it sold at Sotheby's Contemporary Art Auction on Wednesday, November 13, 2013, for $105.4 million.Some of Warhol's work, as well as his own personality, has been described as being Keatonesque. Warhol has been described as playing dumb to the media. He sometimes refused to explain his work. He has suggested that all one needs to know about his work is "already there 'on the surface'."His Rorschach inkblots are intended as pop comments on art and what art could be. His cow wallpaper (literally, wallpaper with a cow motif) and his oxidation paintings (canvases prepared with copper paint that was then oxidized with urine) are also noteworthy in this context. Equally noteworthy is the way these works—and their means of production—mirrored the atmosphere at Andy's New York "Factory". Biographer Bob Colacello provides some details on Andy's "piss paintings": Victor ... was Andy's ghost pisser on the Oxidations. He would come to the Factory to urinate on canvases that had already been primed with copper-based paint by Andy or Ronnie Cutrone, a second ghost pisser much appreciated by Andy, who said that the vitamin B that Ronnie took made a prettier color when the acid in the urine turned the copper green. Did Andy ever use his own urine? My diary shows that when he first began the series, in December 1977, he did, and there were many others: boys who'd come to lunch and drink too much wine, and find it funny or even flattering to be asked to help Andy 'paint'. Andy always had a little extra bounce in his walk as he led them to his studio. Warhol's first portrait of Basquiat (1982) is a black photo-silkscreen over an oxidized copper "piss painting". After many years of silkscreen, oxidation, photography, etc., Warhol returned to painting with a brush in hand in a series of more than 50 large collaborative works done with Jean-Michel Basquiat between 1984 and 1986. Despite negative criticism when these were first shown, Warhol called some of them "masterpieces," and they were influential for his later work.Andy Warhol was commissioned in 1984 by collector and gallerist Alexander Iolas to produce work based on Leonardo da Vinci's The Last Supper for an exhibition at the old refectory of the Palazzo delle Stelline in Milan, opposite from the Santa Maria delle Grazie where Leonardo da Vinci's mural can be seen. Warhol exceeded the demands of the commission and produced nearly 100 variations on the theme, mostly silkscreens and paintings, and among them a collaborative sculpture with Basquiat, the Ten Punching Bags (Last Supper). The Milan exhibition that opened in January 1987 with a set of 22 silk-screens, was the last exhibition for both the artist and the gallerist. The series of The Last Supper was seen by some as "arguably his greatest," but by others as "wishy-washy, religiose" and "spiritless." It is the largest series of religious-themed works by any U.S. artist.Artist Maurizio Cattelan describes that it is difficult to separate daily encounters from the art of Andy Warhol: "That's probably the greatest thing about Warhol: the way he penetrated and summarized our world, to the point that distinguishing between him and our everyday life is basically impossible, and in any case useless." Warhol was an inspiration towards Cattelan's magazine and photography compilations, such as Permanent Food, Charley, and Toilet Paper.In the period just before his death, Warhol was working on Cars, a series of paintings for Mercedes-Benz.A self-portrait by Andy Warhol (1963–64), which sold in New York at the May Post-War and Contemporary evening sale in Christie's, fetched $38.4 million.On May 9, 2012, his classic painting Double Elvis (Ferus Type) sold at auction at Sotheby's in New York for US$33 million. With commission, the sale price totaled US$37,042,500, short of the $50 million that Sotheby's had predicted the painting might bring. The piece (silkscreen ink and spray paint on canvas) shows Elvis Presley in a gunslinger pose. It was first exhibited in 1963 at the Ferus Gallery in Los Angeles. Warhol made 22 versions of the Double Elvis, nine of which are held in museums.In November 2013, his Silver Car Crash (Double Disaster) diptych sold at Sotheby's Contemporary Art Auction for $105.4 million, a new record for the pop artist (pre-auction estimates were at $80 million). Created in 1963, this work had rarely been seen in public in the previous years. In November 2014, Triple Elvis sold for $81.9m (£51.9m) at an auction in New York. === Films === Warhol worked across a wide range of media—painting, photography, drawing, and sculpture. In addition, he was a highly prolific filmmaker. Between 1963 and 1968, he made more than 60 films, plus some 500 short black-and-white "screen test" portraits of Factory visitors. One of his most famous films, Sleep, monitors poet John Giorno sleeping for six hours. The 35-minute film Blow Job is one continuous shot of the face of DeVeren Bookwalter supposedly receiving oral sex from filmmaker Willard Maas, although the camera never tilts down to see this. Another, Empire (1964), consists of eight hours of footage of the Empire State Building in New York City at dusk. The film Eat consists of a man eating a mushroom for 45 minutes. Warhol attended the 1962 premiere of the static composition by LaMonte Young called Trio for Strings and subsequently created his famous series of static films including Kiss, Eat, and Sleep (for which Young initially was commissioned to provide music). Uwe Husslein cites filmmaker Jonas Mekas, who accompanied Warhol to the Trio premiere, and who claims Warhol's static films were directly inspired by the performance.Batman Dracula is a 1964 film that was produced and directed by Warhol, without the permission of DC Comics. It was screened only at his art exhibits. A fan of the Batman series, Warhol's movie was an "homage" to the series, and is considered the first appearance of a blatantly campy Batman. The film was until recently thought to have been lost, until scenes from the picture were shown at some length in the 2006 documentary Jack Smith and the Destruction of Atlantis. Warhol's 1965 film Vinyl is an adaptation of Anthony Burgess' popular dystopian novel A Clockwork Orange. Others record improvised encounters between Factory regulars such as Brigid Berlin, Viva, Edie Sedgwick, Candy Darling, Holly Woodlawn, Ondine, Nico, and Jackie Curtis. Legendary underground artist Jack Smith appears in the film Camp. His most popular and critically successful film was Chelsea Girls (1966). The film was highly innovative in that it consisted of two 16 mm-films being projected simultaneously, with two different stories being shown in tandem. From the projection booth, the sound would be raised for one film to elucidate that "story" while it was lowered for the other. The multiplication of images evoked Warhol's seminal silk-screen works of the early 1960s. Other important films include Bike Boy, My Hustler, and Lonesome Cowboys, a raunchy pseudo-western. These and other titles document gay underground and camp culture, and continue to feature prominently in scholarship about sexuality and art. Warhol was a fan of filmmaker Radley Metzger's film work and commented that Metzger's film, The Lickerish Quartet, was "an outrageously kinky masterpiece". Blue Movie—a film in which Warhol superstar Viva makes love in bed with Louis Waldon, another Warhol superstar—was Warhol's last film as director. The film, a seminal film in the Golden Age of Porn, was, at the time, controversial for its frank approach to a sexual encounter. Blue Movie was publicly screened in New York City in 2005, for the first time in more than 30 years.After his June 3, 1968, shooting, a reclusive Warhol relinquished his personal involvement in filmmaking. His acolyte and assistant director, Paul Morrissey, took over the film-making chores for the Factory collective, steering Warhol-branded cinema towards more mainstream, narrative-based, B-movie exploitation fare with Flesh, Trash, and Heat. All of these films, including the later Andy Warhol's Dracula and Andy Warhol's Frankenstein, were far more mainstream than anything Warhol as a director had attempted. These latter "Warhol" films starred Joe Dallesandro—more of a Morrissey star than a true Warhol superstar. In the early 1970s, most of the films directed by Warhol were pulled out of circulation by Warhol and the people around him who ran his business. After Warhol's death, the films were slowly restored by the Whitney Museum and are occasionally projected at museums and film festivals. Few of the Warhol-directed films are available on video or DVD. ==== Filmography ==== === Factory in New York === Factory: 1342 Lexington Avenue (the first Factory) The Factory: 231 East 47th Street, 1963–67 (the building no longer exists) Factory: 33 Union Square, 1967–73 (Decker Building) Factory: 860 Broadway (near 33 Union Square), 1973–84 (the building has now been completely remodeled and was for a time (2000–2001) the headquarters of the dot-com consultancy Scient) Factory: 22 East 33rd Street, 1984–87 (the building no longer exists) Home: 1342 Lexington Avenue Home: 57 East 66th Street (Warhol's last home) Last personal studio: 158 Madison Avenue === Music === In the mid-1960s, Warhol adopted the band the Velvet Underground, making them a crucial element of the Exploding Plastic Inevitable multimedia performance art show. Warhol, with Paul Morrissey, acted as the band's manager, introducing them to Nico (who would perform with the band at Warhol's request). In 1966 he "produced" their first album The Velvet Underground & Nico, as well as providing its album art. His actual participation in the album's production amounted to simply paying for the studio time. After the band's first album, Warhol and band leader Lou Reed started to disagree more about the direction the band should take, and their artistic friendship ended. In 1989, after Warhol's death, Reed and John Cale re-united for the first time since 1972 to write, perform, record and release the concept album Songs for Drella, a tribute to Warhol. Warhol designed many album covers for various artists starting with the photographic cover of John Wallowitch's debut album, This Is John Wallowitch!!! (1964). He designed the cover art for The Rolling Stones' albums Sticky Fingers (1971) and Love You Live (1977), and the John Cale albums The Academy in Peril (1972) and Honi Soit in 1981. One of Warhol's last works was a portrait of Aretha Franklin for the cover of her 1986 gold album Aretha, which was done in the style of the Reigning Queens series he had completed the year before.Warhol strongly influenced the new wave/punk rock band Devo, as well as David Bowie. Bowie recorded a song called "Andy Warhol" for his 1971 album Hunky Dory. Lou Reed wrote the song "Andy's Chest", about Valerie Solanas, the woman who shot Warhol, in 1968. He recorded it with the Velvet Underground, and this version was released on the VU album in 1985. Bowie would later play Warhol in the 1996 movie, Basquiat. Bowie recalled how meeting Warhol in real life helped him in the role, and recounted his early meetings with him: I met him a couple of times, but we seldom shared more than platitudes. The first time we saw each other an awkward silence fell till he remarked my bright yellow shoes and started talking enthusiastically. He wanted to be very superficial. And seemingly emotionless, indifferent, just like a dead fish. Lou Reed described him most profoundly when he once told me they should bring a doll of Andy on the market: a doll that you wind up and doesn't do anything. But I managed to observe him well, and that was a helping hand for the film [Basquiat]. … We borrowed his clothes from the museum in Pittsburgh, and they were intact, unwashed. Even the pockets weren't emptied: they contained pancake, white, deadly pale fond de teint which Andy always smeared on his face, a check torn in pieces, someone's address, lots of homeopathic pills and a wig. Andy always wore those silver wigs, but he never admitted it were wigs. One of his hairdressers has told me lately that he had his wigs regularly cut, like it were real hair. When the wig was trimmed, he put on another next month as if his hair had grown. === Books and print === Beginning in the early 1950s, Warhol produced several unbound portfolios of his work. The first of several bound self-published books by Warhol was 25 Cats Name Sam and One Blue Pussy, printed in 1954 by Seymour Berlin on Arches brand watermarked paper using his blotted line technique for the lithographs. The original edition was limited to 190 numbered, hand colored copies, using Dr. Martin's ink washes. Most of these were given by Warhol as gifts to clients and friends. Copy No. 4, inscribed "Jerry" on the front cover and given to Geraldine Stutz, was used for a facsimile printing in 1987, and the original was auctioned in May 2006 for US $35,000 by Doyle New York.Other self-published books by Warhol include: A Gold Book Wild Raspberries Holy CatsWarhol's book A La Recherche du Shoe Perdu (1955) marked his "transition from commercial to gallery artist". (The title is a play on words by Warhol on the title of French author Marcel Proust's À la recherche du temps perdu.)After gaining fame, Warhol "wrote" several books that were commercially published: a, A Novel (1968, ISBN 0-8021-3553-6) is a literal transcription—containing spelling errors and phonetically written background noise and mumbling—of audio recordings of Ondine and several of Andy Warhol's friends hanging out at the Factory, talking, going out. The Philosophy of Andy Warhol (From A to B & Back Again) (1975, ISBN 0-15-671720-4)—according to Pat Hackett's introduction to The Andy Warhol Diaries, Pat Hackett did the transcriptions and text for the book based on daily phone conversations, sometimes (when Warhol was traveling) using audio cassettes that Andy Warhol gave her. Said cassettes contained conversations with Brigid Berlin (also known as Brigid Polk) and former Interview magazine editor Bob Colacello. Popism: The Warhol Sixties (1980, ISBN 0-15-672960-1), authored by Warhol and Pat Hackett, is a retrospective view of the 1960s and the role of pop art. The Andy Warhol Diaries (1989, ISBN 0-446-39138-7), edited by Pat Hackett, is a diary dictated by Warhol to Hackett in daily phone conversations. Warhol started the diary to keep track of his expenses after being audited, although it soon evolved to include his personal and cultural observations.Warhol created the fashion magazine Interview that is still published today. The loopy title script on the cover is thought to be either his own handwriting or that of his mother, Julia Warhola, who would often do text work for his early commercial pieces. === Other media === Although Andy Warhol is most known for his paintings and films, he authored works in many different media. Drawing: Warhol started his career as a commercial illustrator, producing drawings in "blotted-ink" style for advertisements and magazine articles. Best known of these early works are his drawings of shoes. Some of his personal drawings were self-published in small booklets, such as Yum, Yum, Yum (about food), Ho, Ho, Ho (about Christmas) and Shoes, Shoes, Shoes. His most artistically acclaimed book of drawings is probably A Gold Book, compiled of sensitive drawings of young men. A Gold Book is so named because of the gold leaf that decorates its pages. In April 2012 a sketch of 1930s singer Rudy Vallee claimed to have been drawn by Andy Warhol was found at a Las Vegas garage sale. The image was said to have been drawn when Andy was nine or 10. Various authorities have challenged the image's authenticity. Sculpture: Warhol's most famous sculpture is probably his Brillo Boxes, silkscreened ink on wood replicas of the large, branded cardboard boxes used to hold 24 packages of Brillo soap pads. The original Brillo design was by commercial artist James Harvey. Warhol's sculpture was part of a series of "grocery carton" works that also included Heinz ketchup and Campbell's tomato juice cases. Other famous works include the Silver Clouds—helium filled, silver mylar, pillow-shaped balloons. A Silver Cloud was included in the traveling exhibition Air Art (1968–1969) curated by Willoughby Sharp. Clouds was also adapted by Warhol for avant-garde choreographer Merce Cunningham's dance piece RainForest (1968). Audio: At one point Warhol carried a portable recorder with him wherever he went, taping everything everybody said and did. He referred to this device as his "wife". Some of these tapes were the basis for his literary work. Another audio-work of Warhol's was his Invisible Sculpture, a presentation in which burglar alarms would go off when entering the room. Warhol's cooperation with the musicians of The Velvet Underground was driven by an expressed desire to become a music producer. Time Capsules: In 1973, Warhol began saving ephemera from his daily life—correspondence, newspapers, souvenirs, childhood objects, even used plane tickets and food—which was sealed in plain cardboard boxes dubbed Time Capsules. By the time of his death, the collection grew to include 600, individually dated "capsules". The boxes are now housed at the Andy Warhol Museum. Television: Andy Warhol dreamed of a television special about a favorite subject of his – Nothing – that he would call The Nothing Special. Later in his career he did create two cable television shows, Andy Warhol's TV in 1982 and Andy Warhol's Fifteen Minutes (based on his famous "fifteen minutes of fame" quotation) for MTV in 1986. Besides his own shows he regularly made guest appearances on other programs, including The Love Boat wherein a Midwestern wife (Marion Ross) fears Andy Warhol will reveal to her husband (Tom Bosley, who starred alongside Ross in sitcom Happy Days) her secret past as a Warhol superstar named Marina del Rey. Warhol also produced a TV commercial for Schrafft's Restaurants in New York City, for an ice cream dessert appropriately titled the "Underground Sundae". Fashion: Warhol is quoted for having said: "I'd rather buy a dress and put it up on the wall, than put a painting, wouldn't you?" One of his most well-known Superstars, Edie Sedgwick, aspired to be a fashion designer, and his good friend Halston was a famous one. Warhol's work in fashion includes silkscreened dresses, a short sub-career as a catwalk-model and books on fashion as well as paintings with fashion (shoes) as a subject. Warhol himself has been described as a modern dandy, whose authority "rested more on presence than on words". Performance Art: Warhol and his friends staged theatrical multimedia happenings at parties and public venues, combining music, film, slide projections and even Gerard Malanga in an S&M outfit cracking a whip. The Exploding Plastic Inevitable in 1966 was the culmination of this area of his work. Theater: Andy Warhol's Pork opened on May 5, 1971, at LaMama theater in New York for a two-week run and was brought to the Roundhouse in London for a longer run in August 1971. Pork was based on tape-recorded conversations between Brigid Berlin and Andy during which Brigid would play for Andy tapes she had made of phone conversations between herself and her mother, socialite Honey Berlin. The play featured Jayne County as "Vulva" and Cherry Vanilla as "Amanda Pork". In 1974, Andy Warhol also produced the stage musical Man on the Moon, which was written by John Phillips of the Mamas and the Papas. Photography: To produce his silkscreens, Warhol made photographs or had them made by his friends and assistants. These pictures were mostly taken with a specific model of Polaroid camera that Polaroid kept in production especially for Warhol. This photographic approach to painting and his snapshot method of taking pictures has had a great effect on artistic photography. Warhol was an accomplished photographer, and took an enormous amount of photographs of Factory visitors, friends. Computer: Warhol used Amiga computers to generate digital art, including You Are the One, which he helped design and build with Amiga, Inc. He also displayed the difference between slow fill and fast fill on live TV with Debbie Harry as a model. (video) === Producer and product === He founded the gossip magazine Interview, a stage for celebrities he "endorsed" and a business staffed by his friends. He collaborated with others on all of his books (some of which were written with Pat Hackett.) He adopted the young painter Jean-Michel Basquiat, and the band The Velvet Underground, presenting them to the public as his latest interest, and collaborating with them. One might even say that he produced people (as in the Warholian "Superstar" and the Warholian portrait). He endorsed products, appeared in commercials, and made frequent celebrity guest appearances on television shows and in films (he appeared in everything from Love Boat to Saturday Night Live and the Richard Pryor movie Dynamite Chicken). In this respect Warhol was a fan of "Art Business" and "Business Art"—he, in fact, wrote about his interest in thinking about art as business in The Philosophy of Andy Warhol from A to B and Back Again. == Personal life == === Sexuality === Warhol was gay. Interviewed in 1980, he indicated that he was still a virgin—biographer Bob Colacello who was present at the interview felt it was probably true and that what little sex he had was probably "a mixture of voyeurism and masturbation—to use [Andy's] word abstract". Warhol's assertion of virginity would seem to be contradicted by his hospital treatment in 1960 for condylomata, a sexually transmitted disease. It has also been contradicted by his lovers, including Warhol muse BillyBoy who has said they had sex to orgasm: "When he wasn't being Andy Warhol and when you were just alone with him he was an incredibly generous and very kind person. What seduced me was the Andy Warhol who I saw alone. In fact when I was with him in public he kind of got on my nerves….I'd say: 'You're just obnoxious, I can't bear you." Asked if Warhol was only a voyeur, Billy Name also denied it, saying: "He was the essence of sexuality. It permeated everything. Andy exuded it, along with his great artistic creativity….It brought a joy to the whole art world in New York." "But his personality was so vulnerable that it became a defense to put up the blank front." Warhol's lovers included John Giorno, Billy Name, Charles Lisanby, and Jon Gould. His boyfriend of 12 years was Jed Johnson, whom he met in 1968, and who later achieved fame as an interior designer.The fact that Warhol's homosexuality influenced his work and shaped his relationship to the art world is a major subject of scholarship on the artist and is an issue that Warhol himself addressed in interviews, in conversation with his contemporaries, and in his publications (e.g., Popism: The Warhol 1960s). Throughout his career, Warhol produced erotic photography and drawings of male nudes. Many of his most famous works (portraits of Liza Minnelli, Judy Garland, and Elizabeth Taylor, and films such as Blow Job, My Hustler and Lonesome Cowboys) draw from gay underground culture or openly explore the complexity of sexuality and desire. As has been addressed by a range of scholars, many of his films premiered in gay porn theaters, including the New Andy Warhol Garrick Theatre and 55th Street Playhouse, in the late 1960s.The first works that Warhol submitted to a fine art gallery, homoerotic drawings of male nudes, were rejected for being too openly gay. In Popism, furthermore, the artist recalls a conversation with the film maker Emile de Antonio about the difficulty Warhol had being accepted socially by the then-more-famous (but closeted) gay artists Jasper Johns and Robert Rauschenberg. De Antonio explained that Warhol was "too swish and that upsets them." In response to this, Warhol writes, "There was nothing I could say to that. It was all too true. So I decided I just wasn't going to care, because those were all the things that I didn't want to change anyway, that I didn't think I 'should' want to change ... Other people could change their attitudes but not me". In exploring Warhol's biography, many turn to this period—the late 1950s and early 1960s—as a key moment in the development of his persona. Some have suggested that his frequent refusal to comment on his work, to speak about himself (confining himself in interviews to responses like "Um, no" and "Um, yes", and often allowing others to speak for him)—and even the evolution of his pop style—can be traced to the years when Warhol was first dismissed by the inner circles of the New York art world. === Religious beliefs === Warhol was a practicing Ruthenian Catholic. He regularly volunteered at homeless shelters in New York City, particularly during the busier times of the year, and described himself as a religious person. Many of Warhol's later works depicted religious subjects, including two series, Details of Renaissance Paintings (1984) and The Last Supper (1986). In addition, a body of religious-themed works was found posthumously in his estate.During his life, Warhol regularly attended Mass, and the priest at Warhol's church, Saint Vincent Ferrer, said that the artist went there almost daily, although he was not observed taking Communion or going to Confession and sat or knelt in the pews at the back. The priest thought he was afraid of being recognized; Warhol said he was self-conscious about being seen in a Roman Rite church crossing himself "in the Orthodox way" (right to left instead of the reverse).His art is noticeably influenced by the Eastern Christian tradition which was so evident in his places of worship.Warhol's brother has described the artist as "really religious, but he didn't want people to know about that because [it was] private". Despite the private nature of his faith, in Warhol's eulogy John Richardson depicted it as devout: "To my certain knowledge, he was responsible for at least one conversion. He took considerable pride in financing his nephew's studies for the priesthood". === Collections === Warhol was an avid collector. His friends referred to his numerous collections, which filled not only his four-story townhouse, but also a nearby storage unit, as "Andy's Stuff." The true extent of his collections was not discovered until after his death, when the Andy Warhol Museum in Pittsburgh took in 641 boxes of his "Stuff." Warhol's collections included a Coca-cola memorabilia sign, and 19th century paintings along with airplane menus, unpaid invoices, pizza dough, pornographic pulp novels, newspapers, stamps, supermarket flyers, and cookie jars, among other eccentricities. It also included significant works of art, such as George Bellows's Miss Bentham. One of his main collections was his wigs. Warhol owned more than 40 and felt very protective of his hairpieces, which were sewn by a New York wig-maker from hair imported from Italy. In 1985 a girl snatched Warhol's wig off his head. It was later discovered in Warhol's diary entry for that day that he wrote: "I don't know what held me back from pushing her over the balcony." Another item found in Warhol's boxes at the museum in Pittsburgh was a mummified human foot from Ancient Egypt. The curator of anthropology at Carnegie Museum of Natural History felt that Warhol most likely found it at a flea market. === Death === Warhol died in Manhattan at 6:32 a.m. on February 22, 1987 at age 58. According to news reports, he had been making a good recovery from gallbladder surgery at New York Hospital before dying in his sleep from a sudden post-operative irregular heartbeat. Prior to his diagnosis and operation, Warhol delayed having his recurring gallbladder problems checked, as he was afraid to enter hospitals and see doctors. His family sued the hospital for inadequate care, saying that the arrhythmia was caused by improper care and water intoxication. The malpractice case was quickly settled out of court; Warhol's family received an undisclosed sum of money.Shortly before Warhol's death, doctors expected Warhol to survive the surgery, though a revaluation of the case about thirty years after his death showed many indications that Warhol's surgery was in fact riskier than originally thought. It was widely reported at the time that Warhol died of a "routine" surgery, though when considering factors such as his age, a family history of gallbladder problems, his previous gunshot wounds, and his medical state in the weeks leading up to the procedure, the potential risk of death following the surgery appeared to have been significant.Warhol's brothers took his body back to Pittsburgh, where an open-coffin wake was held at the Thomas P. Kunsak Funeral Home. The solid bronze casket had gold-plated rails and white upholstery. Warhol was dressed in a black cashmere suit, a paisley tie, a platinum wig, and sunglasses. He was laid out holding a small prayer book and a red rose. The funeral liturgy was held at the Holy Ghost Byzantine Catholic Church on Pittsburgh's North Side. The eulogy was given by Monsignor Peter Tay. Yoko Ono and John Richardson were speakers. The coffin was covered with white roses and asparagus ferns. After the liturgy, the coffin was driven to St. John the Baptist Byzantine Catholic Cemetery in Bethel Park, a south suburb of Pittsburgh.At the grave, the priest said a brief prayer and sprinkled holy water on the casket. Before the coffin was lowered, Paige Powell dropped a copy of Interview magazine, an Interview T-shirt, and a bottle of the Estee Lauder perfume "Beautiful" into the grave. Warhol was buried next to his mother and father. A memorial service was held in Manhattan for Warhol on April 1, 1987, at St. Patrick's Cathedral, New York. == Foundation == Warhol's will dictated that his entire estate—with the exception of a few modest legacies to family members—would go to create a foundation dedicated to the "advancement of the visual arts". Warhol had so many possessions that it took Sotheby's nine days to auction his estate after his death; the auction grossed more than US$20 million. In 1987, in accordance with Warhol's will, the Andy Warhol Foundation for the Visual Arts began. The foundation serves as the estate of Andy Warhol, but also has a mission "to foster innovative artistic expression and the creative process" and is "focused primarily on supporting work of a challenging and often experimental nature."The Artists Rights Society is the U.S. copyright representative for the Andy Warhol Foundation for the Visual Arts for all Warhol works with the exception of Warhol film stills. The U.S. copyright representative for Warhol film stills is the Warhol Museum in Pittsburgh. Additionally, the Andy Warhol Foundation for the Visual Arts has agreements in place for its image archive. All digital images of Warhol are exclusively managed by Corbis, while all transparency images of Warhol are managed by Art Resource.The Andy Warhol Foundation released its 20th Anniversary Annual Report as a three-volume set in 2007: Vol. I, 1987–2007; Vol. II, Grants & Exhibitions; and Vol. III, Legacy Program. The Foundation remains one of the largest grant-giving organizations for the visual arts in the U.S.Many of Warhol's works and possessions are on display at The Andy Warhol Museum in Pittsburgh. The foundation donated more than 3,000 works of art to the museum. == Media about Warhol == === Films === Warhol appeared as himself in the film Cocaine Cowboys (1979).After his death, Warhol was portrayed by Crispin Glover in Oliver Stone's film The Doors (1991), by David Bowie in Julian Schnabel's film Basquiat (1996), and by Jared Harris in Mary Harron's film I Shot Andy Warhol (1996). Warhol appears as a character in Michael Daugherty's opera Jackie O (1997). Actor Mark Bringleson makes a brief cameo as Warhol in Austin Powers: International Man of Mystery (1997). Many films by avant-garde cineast Jonas Mekas have caught the moments of Warhol's life. Sean Gregory Sullivan depicted Warhol in the film 54 (1998). Guy Pearce portrayed Warhol in the film Factory Girl (2007) about Edie Sedgwick's life. Actor Greg Travis portrays Warhol in a brief scene from the film Watchmen (2009). In the movie Highway to Hell a group of Andy Warhols are part of the Good Intentions Paving Company where good-intentioned souls are ground into pavement.In the film Men in Black 3 (2012) Andy Warhol turns out to really be undercover MIB Agent W (played by Bill Hader). Warhol is throwing a party at The Factory in 1969, where he is looked up by MIB Agents K and J (J from the future). Agent W is desperate to end his undercover job ("I'm so out of ideas I'm painting soup cans and bananas, for Christ sakes!", "You gotta fake my death, okay? I can't listen to sitar music anymore." and "I can't tell the girls from the boys."). Andy Warhol (portrayed by Tom Meeten) is one of main characters of the 2012 British television show Noel Fielding's Luxury Comedy. The character is portrayed as having robot-like mannerisms. Gus Van Sant was planning a version of Warhol's life with River Phoenix in the lead role just before Phoenix's death in 1993.In the 2017 feature The Billionaire Boys Club Cary Elwes portrays Warhol in a film based on the true story about Ron Levin (portrayed by Kevin Spacey) a friend of Warhol's who was murdered in 1986.In September 2016, it was announced that Jared Leto would portray the title character in Warhol, an upcoming American biographical drama film produced by Michael De Luca and written by Terence Winter, based on the book Warhol: The Biography by Victor Bockris. === Documentaries === The documentary Absolut Warhola (2001) was produced by Polish director Stanislaw Mucha, featuring Warhol's parents' family and hometown in Slovakia. Andy Warhol: A Documentary Film (2006) is a reverential, four-hour movie by Ric Burns that won a Peabody Award in 2006. Andy Warhol: Double Denied (2006) is a 52-minute movie by Ian Yentob about the difficulties authenticating Warhol's work. Andy Warhol's People Factory (2008), a three-part television documentary directed by Catherine Shorr, features interviews with several of Warhol's associates. === Television === Warhol appeared as a recurring character in TV series Vinyl, played by John Cameron Mitchell. In the episode of The Simpsons "Mom and Pop Art", Warhol appears in Homer's nightmare, throwing soup cans at Homer. Warhol was portrayed by Evan Peters in the American Horror Story: Cult episode "Valerie Solanas Died for Your Sins: Scumbag". The episode depicts the attempted assassination of Warhol by Valerie Solanas (Lena Dunham). == Honors == In 2002, the U.S. Postal Service issued an 18-cent stamp commemorating Warhol. Designed by Richard Sheaff of Scottsdale, Arizona, the stamp was unveiled at a ceremony at The Andy Warhol Museum and features Warhol's painting "Self-Portrait, 1964". In March 2011, a chrome statue of Andy Warhol and his Polaroid camera was revealed at Union Square in New York City. == See also == == References == == Further reading == == External links == Andy Warhol at Encyclopædia Britannica Andy Warhol at the National Gallery of Art Warhol Foundation in New York City Andy Warhol Collection in Pittsburgh The work of Andy Warhol spoken about by David Cronenberg Warholstars: Andy Warhol Films, Art and Superstars Warhol & The Computer Andy Warhol Andy Warhol at the Jewish Museum ### Answer: <1928 births>, <1987 deaths>, <20th-century American writers>, <20th-century artists>, <20th-century painters>, <Album-cover and concert-poster artists>, <American Eastern Catholics>, <American cinematographers>, <American contemporary artists>, <American experimental filmmakers>, <American film directors>, <American film directors of Hungarian descent>, <American film producers>, <American painters>, <American people of Hungarian descent>, <American people of Lemko descent>, <American people of Rusyn descent>, <American people of Slovak descent>, <American pop artists>, <American portrait painters>, <American printmakers>, <American screenwriters>, <American shooting survivors>, <American socialites>, <Andy Warhol>, <Artists from New York>, <Artists from Pittsburgh, Pennsylvania>, <Burials in Pennsylvania>, <Carnegie Mellon University alumni>, <Censorship in the arts>, <Counterculture of the 1960s>, <Deaths from myocardial infarction>, <Deaths from surgical complications>, <Fashion illustrators>, <Film directors from Pennsylvania>, <Gay artists>, <Gay writers>, <LGBT Roman Catholics>, <LGBT artists from the United States>, <LGBT directors>, <LGBT people from New York>, <LGBT people from Pennsylvania>, <LGBT producers>, <LGBT writers from the United States>, <Photographers from New York>, <Pop artists>, <Postmodern artists>, <Ruthenian Catholics>, <Schenley High School alumni>, <The Velvet Underground>, <Warhola family>, <Writers from New York>, <Writers from Pittsburgh, Pennsylvania>

### Instruction: retrieve labels for this: Alp Arslan (honorific in Turkish meaning "Heroic Lion"; in Persian: آلپ ارسلان‎; full name: Diya ad-Dunya wa ad-Din Adud ad-Dawlah Abu Shuja Muhammad Alp Arslan ibn Dawud ابو شجاع محمد آلپ ارسلان ابن داود;‎ 20 January 1029 – 15 December 1072), real name Muhammad bin Dawud Chaghri, was the second Sultan of the Seljuk Empire and great-grandson of Seljuk, the eponymous founder of the dynasty. As Sultan, Alp Arslan greatly expanded Seljuk territory and consolidated power, defeating rivals to his south and northwest. His victory over the Byzantines at the Battle of Manzikert in 1071 ushered in the Turkish settlement of Anatolia. For his military prowess and fighting skills he obtained the name Alp Arslan, which means "Heroic Lion" in Turkish. == Early career == Alp Arslan accompanied his uncle, Tughril Bey, on campaigns in the south against the Shia Fatimids while his father, Çağrı Bey, remained in Khorasan. Upon Alp Arslan's return to Khorasan, he began his work in administration at his father's suggestion. While there, his father introduced him to Nizam al-Mulk, one of the most eminent statesmen in early Muslim history and Alp Arslan's future vizier.After the death of his father, Alp Arslan succeeded him as governor of Khorasan in 1059. His uncle Tughril died in 1063 and was succeeded by Suleiman, Arslan's brother. Arslan and his uncle Kutalmish both contested this succession. (see Battle of Damghan (1063)) Arslan defeated Kutalmish for the throne and succeeded on 27 April 1064 as sultan of Great Seljuq, thus becoming sole monarch of Persia from the river Oxus to the Tigris. In consolidating his empire and subduing contending factions, Arslan was ably assisted by Nizam al-Mulk, and the two are credited with helping to stabilize the empire after the death of Tughril. With peace and security established in his dominions, Arslan convoked an assembly of the states and in 1066, he declared his son Malik Shah I his heir and successor. With the hope of capturing Caesarea Mazaca, the capital of Cappadocia, he placed himself at the head of the Turkish cavalry, crossed the Euphrates, and entered and invaded the city. Along with Nizam al-Mulk, he then marched into Armenia and Georgia, which he conquered in 1064. After a siege of 25 days, the Seljuks captured Ani, the capital city of Armenia.}} == Byzantine struggle == En route to fight the Fatimids in Syria in 1068, Alp Arslan invaded the Byzantine Empire. The Emperor Romanos IV Diogenes, assuming command in person, met the invaders in Cilicia. In three arduous campaigns, the Turks were defeated in detail and driven across the Euphrates in 1070. The first two campaigns were conducted by the emperor himself, while the third was directed by Manuel Comnenos, great-uncle of Emperor Manuel Comnenos. During this time, Arslan gained the allegiance of Rashid al-Dawla Mahmud, the Mirdasid emir of Aleppo. In 1071 Romanos again took the field and advanced into Armenia with possibly 30,000 men, including a contingent of Cuman Turks as well as contingents of Franks and Normans, under Ursel de Baieul. Alp Arslan, who had moved his troops south to fight the Fatimids, quickly reversed to meet the Byzantines. At Manzikert, on the Murat River, north of Lake Van, the two forces waged the Battle of Manzikert. The Cuman mercenaries among the Byzantine forces immediately defected to the Turkish side. Seeing this, "the Western mercenaries rode off and took no part in the battle." To be exact, Romanos was betrayed by general Andronikos Doukas, son of the Caesar (Romanos's stepson), who pronounced him dead and rode off with a large part of the Byzantine forces at a critical moment. The Byzantines were totally routed. Emperor Romanos IV was himself taken prisoner and conducted into the presence of Alp Arslan. After a ritual humiliation, Arslan treated him with generosity. After peace terms were agreed to, Arslan dismissed the Emperor, loaded with presents and respectfully attended by a military guard. The following conversation is said to have taken place after Romanos was brought as a prisoner before the Sultan: Alp Arslan's victories changed the balance in near Asia completely in favour of the Seljuq Turks and Sunni Muslims. While the Byzantine Empire was to continue for nearly four more centuries, and the Crusades would contest the issue for some time, the victory at Manzikert signalled the beginning of Turkish ascendancy in Anatolia. Most historians, including Edward Gibbon, date the defeat at Manzikert as the beginning of the end of the Eastern Roman Empire. == State organization == Alp Arslan's strength lay in the military realm. Domestic affairs were handled by his able vizier, Nizam al-Mulk, the founder of the administrative organization that characterized and strengthened the sultanate during the reigns of Alp Arslan and his son, Malik Shah. Military fiefs, governed by Seljuq princes, were established to provide support for the soldiery and to accommodate the nomadic Turks to the established Anatolian agricultural scene. This type of military fiefdom enabled the nomadic Turks to draw on the resources of the sedentary Persians, Turks, and other established cultures within the Seljuq realm, and allowed Alp Arslan to field a huge standing army without depending on tribute from conquest to pay his soldiers. He not only had enough food from his subjects to maintain his military, but the taxes collected from traders and merchants added to his coffers sufficiently to fund his continuous wars. According to the poet Saadi Shirazi: Arslan possessed a fort, which raised at the height of Alwand, from all were those within its walls, for its roads were a labyrinth, like the curls of a bride. From a learned traveler Arslan once inquired: "Didst thou ever, in thy wanderings, see a fort as strong as this?" "Splendid it is," was the traveler's reply, "but methinks not it confers much strength. Before thee, did not other kings possess it for a while, then pass away? After thee, will not other kings assume control, and eat the fruits of the tree of thy hope?" In the estimation of the wise, the world is a false gem that passes each moment from one hand to another. (The fort was sacked by the Mongols led by Hulagu.) Suleiman ibn Kutalmish was the son of the contender for Arslan's throne; he was appointed governor of the north-western provinces and assigned to completing the invasion of Anatolia. An explanation for this choice can only be conjectured from Ibn al-Athir’s account of the battle between Alp-Arslan and Kutalmish, in which he writes that Alp-Arslan wept for the latter's death and greatly mourned the loss of his kinsman. == Death == After Manzikert, the dominion of Alp Arslan extended over much of western Asia. He soon prepared to march for the conquest of Turkestan, the original seat of his ancestors. With a powerful army he advanced to the banks of the Oxus. Before he could pass the river with safety, however, it was necessary to subdue certain fortresses, one of which was for several days vigorously defended by the governor, Yussuf al-Kharezmi, a Khwarezmian. He was obliged to surrender, however, and was carried as a prisoner before the sultan, who condemned him to death. Yussuf, in desperation, drew his dagger and rushed upon the sultan. Alp Arslan, who took great pride in his reputation as an archer, motioned to his guards not to interfere. He drew his bow, but his foot slipped, the arrow glanced aside, and he received the assassin's dagger in his breast. Alp Arslan died from this wound four days later, on 25 November 1072, in his 42nd year, and he was taken to Merv to be buried next to his father, Chaghri Beg. == Legacy == Alp Arslan is widely regarded as having begun Anatolianism, although unintentionally. His victory at Manzikert is often cited as the beginning of the end of Byzantine power in Anatolia, and the beginning of Turkish identity there. Alp Arslan's conquest of Anatolia from the Byzantines is also seen as one of the pivotal precursors to the launch of the crusades. From 2002 to July 2008 under Turkmen calendar reform, the month of August was named after Alp Arslan. == References == == Sources == Bosworth, C. E. (1968).

### Instruction: retrieve labels for this: Akira Kurosawa (黒沢 明, Kurosawa Akira, March 23, 1910 – September 6, 1998) was a Japanese film director and screenwriter, who directed 30 films in a career spanning 57 years. He is regarded as one of the most important and influential filmmakers in the history of cinema. Kurosawa entered the Japanese film industry in 1936, following a brief stint as a painter. After years of working on numerous films as an assistant director and scriptwriter, he made his debut as a director during World War II with the popular action film Sanshiro Sugata (a.k.a. Judo Saga). After the war, the critically acclaimed Drunken Angel (1948), in which Kurosawa cast then-unknown actor Toshiro Mifune in a starring role, cemented the director's reputation as one of the most important young filmmakers in Japan. The two men would go on to collaborate on another 15 films. Rashomon, which premiered in Tokyo, became the surprise winner of the Golden Lion at the 1952 Venice Film Festival. The commercial and critical success of that film opened up Western film markets for the first time to the products of the Japanese film industry, which in turn led to international recognition for other Japanese filmmakers. Kurosawa directed approximately one film per year throughout the 1950s and early 1960s, including a number of highly regarded (and often adapted) films, such as Ikiru (1952), Seven Samurai (1954) and Yojimbo (1961). After the 1960s he became much less prolific; even so, his later work—including his final two epics, Kagemusha (1980) and Ran (1985)—continued to win awards, though more often abroad than in Japan. In 1990, he accepted the Academy Award for Lifetime Achievement. Posthumously, he was named "Asian of the Century" in the "Arts, Literature, and Culture" category by AsianWeek magazine and CNN, cited there as being among the five people who most prominently contributed to the improvement of Asia in the 20th century. His career has been honored by many retrospectives, critical studies and biographies in both print and video, and by releases in many consumer media formats. == Biography == === Childhood to war years (1910–1945) === ==== Childhood and youth (1910–35) ==== Kurosawa (Japanese: 黒澤 明) was born on March 23, 1910, in Ōimachi in the Ōmori district of Tokyo. His father Isamu (1864–1948), a member of a samurai family from Akita Prefecture, worked as the director of the Army's Physical Education Institute's lower secondary school, while his mother Shima (1870–1952) came from a merchant's family living in Osaka. Akira was the eighth and youngest child of the moderately wealthy family, with two of his siblings already grown up at the time of his birth and one deceased, leaving Kurosawa to grow up with three sisters and a brother.In addition to promoting physical exercise, Isamu Kurosawa was open to Western traditions and considered theater and motion pictures to have educational merit. He encouraged his children to watch films; young Akira viewed his first movies at the age of six. An important formative influence was his elementary school teacher Mr Tachikawa, whose progressive educational practices ignited in his young pupil first a love of drawing and then an interest in education in general. During this time, the boy also studied calligraphy and Kendo swordsmanship.Another major childhood influence was Heigo Kurosawa, Akira's older brother by four years. In the aftermath of the Great Kantō earthquake of 1923, which devastated Tokyo, Heigo took the 13-year-old Akira to view the devastation. When the younger brother wanted to look away from the human corpses and animal carcasses scattered everywhere, Heigo forbade him to do so, instead encouraging Akira to face his fears by confronting them directly. Some commentators have suggested that this incident would influence Kurosawa's later artistic career, as the director was seldom hesitant to confront unpleasant truths in his work.Heigo was academically gifted, but soon after failing to secure a place in Tokyo's foremost high school, he began to detach himself from the rest of the family, preferring to concentrate on his interest in foreign literature. In the late 1920s, Heigo became a benshi (silent film narrator) for Tokyo theaters showing foreign films, and quickly made a name for himself. Akira, who at this point planned to become a painter, moved in with him, and the two brothers became inseparable. With Heigo's guidance, Akira devoured not only films but also theater and circus performances, while exhibiting his paintings and working for the left-wing Proletarian Artists' League. However, he was never able to make a living with his art, and, as he began to perceive most of the proletarian movement as "putting unfulfilled political ideals directly onto the canvas", he lost his enthusiasm for painting.With the increasing production of talking pictures in the early 1930s, film narrators like Heigo began to lose work, and Akira moved back in with his parents. In July 1933, Heigo committed suicide. Kurosawa has commented on the lasting sense of loss he felt at his brother's death and the chapter of his autobiography (Something Like an Autobiography) that describes it—written nearly half a century after the event—is titled, "A Story I Don't Want to Tell". Only four months later, Kurosawa's eldest brother also died, leaving Akira, at age 23, the only one of the Kurosawa brothers still living, together with his three surviving sisters. ==== Director in training (1935–41) ==== In 1935, the new film studio Photo Chemical Laboratories, known as P.C.L. (which later became the major studio, Toho), advertised for assistant directors. Although he had demonstrated no previous interest in film as a profession, Kurosawa submitted the required essay, which asked applicants to discuss the fundamental deficiencies of Japanese films and find ways to overcome them. His half-mocking view was that if the deficiencies were fundamental, there was no way to correct them. Kurosawa's essay earned him a call to take the follow-up exams, and director Kajirō Yamamoto, who was among the examiners, took a liking to Kurosawa and insisted that the studio hire him. The 25-year-old Kurosawa joined P.C.L. in February 1936.During his five years as an assistant director, Kurosawa worked under numerous directors, but by far the most important figure in his development was Yamamoto. Of his 24 films as A.D., he worked on 17 under Yamamoto, many of them comedies featuring the popular actor Ken'ichi Enomoto, known as "Enoken". Yamamoto nurtured Kurosawa's talent, promoting him directly from third assistant director to chief assistant director after a year. Kurosawa's responsibilities increased, and he worked at tasks ranging from stage construction and film development to location scouting, script polishing, rehearsals, lighting, dubbing, editing and second-unit directing. In the last of Kurosawa's films as an assistant director for Yamamoto, Horse (Uma, 1941), Kurosawa took over most of the production, as his mentor was occupied with the shooting of another film.One important piece of advice Yamamoto gave Kurosawa was that a good director needed to master screenwriting. Kurosawa soon realized that the potential earnings from his scripts were much higher than what he was paid as an assistant director. Kurosawa would later write or co-write all of his own films. He also frequently wrote screenplays for other directors such as for the antiwar film director Satsuo Yamamoto's film, A Triumph of Wings (Tsubasa no gaika, 1942). This outside scriptwriting would serve Kurosawa as a lucrative sideline lasting well into the 1960s, long after he became world-famous. ==== Wartime films and marriage (1942–45) ==== In the two years following the release of Horse in 1941, Kurosawa searched for a story he could use to launch his directing career. Towards the end of 1942, about a year after the Japanese attack on Pearl Harbor, novelist Tsuneo Tomita published his Musashi Miyamoto-inspired judo novel, Sanshiro Sugata, the advertisements for which intrigued Kurosawa. He bought the book on its publication day, devoured it in one sitting, and immediately asked Toho to secure the film rights. Kurosawa's initial instinct proved correct as, within a few days, three other major Japanese studios also offered to buy the rights. Toho prevailed, and Kurosawa began pre-production on his debut work as director. Shooting of Sanshiro Sugata began on location in Yokohama in December 1942. Production proceeded smoothly, but getting the completed film past the censors was an entirely different matter. The censorship office considered the work to be objectionably "British-American" by the standards of wartime Japan, and it was only through the intervention of director Yasujirō Ozu, who championed the film, that Sanshiro Sugata was finally accepted for release on March 25, 1943. (Kurosawa had just turned 33.) The movie became both a critical and commercial success. Nevertheless, the censorship office would later decide to cut out some 18 minutes of footage, much of which is now considered lost.He next turned to the subject of wartime female factory workers in The Most Beautiful, a propaganda film which he shot in a semi-documentary style in early 1944. In order to coax realistic performances from his actresses, the director had them live in a real factory during the shoot, eat the factory food and call each other by their character names. He would use similar methods with his performers throughout his career.During production, the actress playing the leader of the factory workers, Yōko Yaguchi, was chosen by her colleagues to present their demands to the director. She and Kurosawa were constantly at loggerheads, and it was through these arguments that the two, paradoxically, became close. They married on May 21, 1945, with Yaguchi two months pregnant (she never resumed her acting career), and the couple would remain together until her death in 1985. They would have two children, both surviving Kurosawa as of 2018: a son, Hisao, born December 20, 1945, who would serve as producer on some of his father's last projects, and Kazuko, a daughter, born April 29, 1954, who would become a costume designer.Shortly before his marriage, Kurosawa was pressured by the studio against his will to direct a sequel to his debut film. The often blatantly propagandistic Sanshiro Sugata Part II, which premiered in May 1945, is generally considered one of his weakest pictures.Kurosawa decided to write the script for a film that would be both censor-friendly and less expensive to produce. The Men Who Tread on the Tiger's Tail, based on the Kabuki play Kanjinchō and starring the comedian Enoken, with whom Kurosawa had often worked during his assistant director days, was completed in September 1945. By this time, Japan had surrendered and the occupation of Japan had begun. The new American censors interpreted the values allegedly promoted in the picture as overly "feudal" and banned the work. (It would not be released until 1952, the year another Kurosawa film, Ikiru, was also released.) Ironically, while in production, the film had already been savaged by Japanese wartime censors as too Western and "democratic" (they particularly disliked the comic porter played by Enoken), so the movie most probably would not have seen the light of day even if the war had continued beyond its completion. === Early postwar years to Red Beard (1946–1965) === ==== First postwar works (1946–50) ==== After the war, Kurosawa, influenced by the democratic ideals of the Occupation, sought to make films that would establish a new respect towards the individual and the self. The first such film, No Regrets for Our Youth (1946), inspired by both the 1933 Takigawa incident and the Hotsumi Ozaki wartime spy case, criticized Japan's prewar regime for its political oppression. Atypically for the director, the heroic central character is a woman, Yukie (Setsuko Hara), who born into upper-middle-class privilege, comes to question her values in a time of political crisis. The original script had to be extensively rewritten and, because of its controversial theme (and because the protagonist was a woman), the completed work divided critics, but it nevertheless managed to win the approval of audiences, who turned variations on the film's title into a postwar catchphrase.His next film, One Wonderful Sunday premiered in July 1947 to mixed reviews. It is a relatively uncomplicated and sentimental love story dealing with an impoverished postwar couple trying to enjoy, within the devastation of postwar Tokyo, their one weekly day off. The movie bears the influence of Frank Capra, D. W. Griffith and F. W. Murnau, each of whom was among Kurosawa's favorite directors. Another film released in 1947 with Kurosawa's involvement was the action-adventure thriller, Snow Trail, directed by Senkichi Taniguchi from Kurosawa's screenplay. It marked the debut of the intense young actor Toshiro Mifune. It was Kurosawa who, with his mentor Yamamoto, had intervened to persuade Toho to sign Mifune, during an audition in which the young man greatly impressed Kurosawa, but managed to alienate most of the other judges. Drunken Angel is often considered the director's first major work. Although the script, like all of Kurosawa's occupation-era works, had to go through forced rewrites due to American censorship, Kurosawa felt that this was the first film in which he was able to express himself freely. A grittily realistic story of a doctor who tries to save a gangster (yakuza) with tuberculosis, it was also the director's first film with Toshiro Mifune, who would proceed to play either the main or a major character in all but one (Ikiru) of the director's next 16 films. While Mifune was not cast as the protagonist in Drunken Angel, his explosive performance as the gangster so dominates the drama that he shifted the focus from the title character, the alcoholic doctor played by Takashi Shimura, who had already appeared in several Kurosawa movies. However, Kurosawa did not want to smother the young actor's immense vitality, and Mifune's rebellious character electrified audiences in much the way that Marlon Brando's defiant stance would startle American film audiences a few years later. The film premiered in Tokyo in April 1948 to rave reviews and was chosen by the prestigious Kinema Junpo critics poll as the best film of its year, the first of three Kurosawa movies to be so honored.Kurosawa, with producer Sōjirō Motoki and fellow directors and friends Kajiro Yamamoto, Mikio Naruse and Senkichi Taniguchi, formed a new independent production unit called Film Art Association (Eiga Geijutsu Kyōkai). For this organization's debut work, and first film for Daiei studios, Kurosawa turned to a contemporary play by Kazuo Kikuta and, together with Taniguchi, adapted it for the screen. The Quiet Duel starred Toshiro Mifune as an idealistic young doctor struggling with syphilis, a deliberate attempt by Kurosawa to break the actor away from being typecast as gangsters. Released in March 1949, it was a box office success, but is generally considered one of the director's lesser achievements.His second film of 1949, also produced by Film Art Association and released by Shintoho, was Stray Dog. It is a detective movie (perhaps the first important Japanese film in that genre) that explores the mood of Japan during its painful postwar recovery through the story of a young detective, played by Mifune, and his fixation on the recovery of his handgun, which was stolen by a penniless war veteran who proceeds to use it to rob and murder. Adapted from an unpublished novel by Kurosawa in the style of a favorite writer of his, Georges Simenon, it was the director's first collaboration with screenwriter Ryuzo Kikushima, who would later help to script eight other Kurosawa films. A famous, virtually wordless sequence, lasting over eight minutes, shows the detective, disguised as an impoverished veteran, wandering the streets in search of the gun thief; it employed actual documentary footage of war-ravaged Tokyo neighborhoods shot by Kurosawa's friend, Ishirō Honda, the future director of Godzilla. The film is considered a precursor to the contemporary police procedural and buddy cop film genres.Scandal, released by Shochiku in April 1950, was inspired by the director's personal experiences with, and anger towards, Japanese yellow journalism. The work is an ambitious mixture of courtroom drama and social problem film about free speech and personal responsibility, but even Kurosawa regarded the finished product as dramatically unfocused and unsatisfactory, and almost all critics agree. However, it would be Kurosawa's second film of 1950, Rashomon, that would ultimately win him, and Japanese cinema, a whole new international audience. ==== International recognition (1950–58) ==== After finishing Scandal, Kurosawa was approached by Daiei studios, which asked the director to make another film for them. Kurosawa picked a script by an aspiring young screenwriter, Shinobu Hashimoto, who would survive Kurosawa by 20 years and with whom he would eventually work on nine of his films. Their first joint effort was based on Ryūnosuke Akutagawa's experimental short story "In a Grove", which recounts the murder of a samurai and the rape of his wife from various different and conflicting points-of-view. Kurosawa saw potential in the script, and with Hashimoto's help, polished and expanded it and then pitched it to Daiei, who were happy to accept the project due to its low budget.Shooting of Rashomon began on July 7, 1950, and, after extensive location work in the primeval forest of Nara, wrapped on August 17. Just one week was spent in hurried post-production, hampered by a studio fire, and the finished film premiered at Tokyo's Imperial Theatre on August 25, expanding nationwide the following day. The movie was met by lukewarm reviews, with many critics puzzled by its unique theme and treatment, but it was nevertheless a moderate financial success for Daiei. Kurosawa's next film, for Shochiku, was The Idiot, an adaptation of the novel by the director's favorite writer, Fyodor Dostoyevsky. The filmmaker relocated the story from Russia to Hokkaido, but it is otherwise very faithful to the original, a fact seen by many critics as detrimental to the work. A studio-mandated edit shortened it from Kurosawa's original cut of 265 minutes (nearly four-and-a-half hours) to just 166 minutes, making the resulting narrative exceedingly difficult to follow. The severely edited film version is widely considered today to be one of the director's least successful works and the original full length version no longer exists. Contemporary reviews of the much shortened edited version were very negative, but the film was a moderate success at the box office, largely because of the popularity of one of its stars, Setsuko Hara.Meanwhile, unbeknownst to Kurosawa, Rashomon had been entered in the prestigious Venice Film Festival, due to the efforts of Giuliana Stramigioli, a Japan-based representative of an Italian film company, who had seen and admired the movie and convinced Daiei to submit it. On September 10, 1951, Rashomon was awarded the festival's highest prize, the Golden Lion, shocking not only Daiei but the international film world, which at the time was largely unaware of Japan's decades-old cinematic tradition.After Daiei very briefly exhibited a subtitled print of the film in Los Angeles, RKO purchased distribution rights to Rashomon in the United States. The company was taking a considerable gamble. It had put out only one prior subtitled film in the American market, and the only previous Japanese talkie commercially released in New York had been Mikio Naruse's comedy, Wife! Be Like a Rose, in 1937: a critical and box-office flop. However, Rashomon's commercial run, greatly helped by strong reviews from critics and even the columnist Ed Sullivan, was very successful. (It earned $35,000 in its first three weeks at a single New York theater, an almost unheard-of sum at the time.) This success in turn led to a vogue in America and the West for Japanese movies throughout the 1950s, replacing the enthusiasm for Italian neorealist cinema. For example, by the end of 1952 Rashomon was released in Japan, the United States, and most of Europe. Among the Japanese filmmakers whose work, as a result, began to win festival prizes and commercial release in the West were Kenji Mizoguchi (The Life of Oharu, Ugetsu, Sansho the Bailiff) and, somewhat later, Yasujirō Ozu (Tokyo Story, An Autumn Afternoon)—artists highly respected in Japan but, prior to this period, almost totally unknown in the West. Kurosawa's growing reputation among Western audiences in the 1950s would make Western audiences more sympathetic to the reception of later generations of Japanese filmmakers ranging from Kon Ichikawa, Masaki Kobayashi, Nagisa Oshima and Shohei Imamura to Juzo Itami, Takeshi Kitano and Takashi Miike. His career boosted by his sudden international fame, Kurosawa, now reunited with his original film studio, Toho (which would go on to produce his next 11 films), set to work on his next project, Ikiru. The movie stars Takashi Shimura as a cancer-ridden Tokyo bureaucrat, Watanabe, on a final quest for meaning before his death. For the screenplay, Kurosawa brought in Hashimoto as well as writer Hideo Oguni, who would go on to co-write 12 Kurosawa films. Despite the work's grim subject matter, the screenwriters took a satirical approach, which some have compared to the work of Brecht, to both the bureaucratic world of its hero and the U.S. cultural colonization of Japan. (American pop songs figure prominently in the film.) Because of this strategy, the filmmakers are usually credited with saving the picture from the kind of sentimentality common to dramas about characters with terminal illnesses. Ikiru opened in October 1952 to rave reviews—it won Kurosawa his second Kinema Junpo "Best Film" award—and enormous box office success. It remains the most acclaimed of all the artist's films set in the modern era.In December 1952, Kurosawa took his Ikiru screenwriters, Shinobu Hashimoto and Hideo Oguni, for a forty-five-day secluded residence at an inn to create the screenplay for his next movie, Seven Samurai. The ensemble work was Kurosawa's first proper samurai film, the genre for which he would become most famous. The simple story, about a poor farming village in Sengoku period Japan that hires a group of samurai to defend it against an impending attack by bandits, was given a full epic treatment, with a huge cast (largely consisting of veterans of previous Kurosawa productions) and meticulously detailed action, stretching out to almost three-and-a-half hours of screen time.Three months were spent in pre-production and a month in rehearsals. Shooting took up 148 days spread over almost a year, interrupted by production and financing troubles and Kurosawa's health problems. The film finally opened in April 1954, half a year behind its original release date and about three times over budget, making it at the time the most expensive Japanese film ever made. (However, by Hollywood standards, it was a quite modestly budgeted production, even for that time). The film received positive critical reaction and became a big hit, quickly making back the money invested in it and providing the studio with a product that they could, and did, market internationally—though with extensive edits. Over time—and with the theatrical and home video releases of the uncut version—its reputation has steadily grown. It is now regarded by some commentators as the greatest Japanese film ever made, and in 1979, a poll of Japanese film critics also voted it the best Japanese film ever made. In the most recent (2012) version of the widely respected British Film Institute (BFI) Sight & Sound "Greatest Films of All Time" poll, Seven Samurai placed 17th among all films from all countries in both the critics' and the directors' polls, receiving a place in the Top Ten lists of 48 critics and 22 directors.In 1954, nuclear tests in the Pacific were causing radioactive rainstorms in Japan and one particular incident in March had exposed a Japanese fishing boat to nuclear fallout, with disastrous results. It is in this anxious atmosphere that Kurosawa's next film, Record of a Living Being, was conceived. The story concerned an elderly factory owner (Toshiro Mifune) so terrified of the prospect of a nuclear attack that he becomes determined to move his entire extended family (both legal and extra-marital) to what he imagines is the safety of a farm in Brazil. Production went much more smoothly than the director's previous film, but a few days before shooting ended, Kurosawa's composer, collaborator and close friend Fumio Hayasaka died (of tuberculosis) at the age of 41. The film's score was finished by Hayasaka's student, Masaru Sato, who would go on to score all of Kurosawa's next eight films. Record of a Living Being opened in November 1955 to mixed reviews and muted audience reaction, becoming the first Kurosawa film to lose money during its original theatrical run. Today, it is considered by many to be among the finest films dealing with the psychological effects of the global nuclear stalemate.Kurosawa's next project, Throne of Blood, an adaptation of William Shakespeare's Macbeth—set, like Seven Samurai, in the Sengoku Era—represented an ambitious transposition of the English work into a Japanese context. Kurosawa instructed his leading actress, Isuzu Yamada, to regard the work as if it were a cinematic version of a Japanese rather than a European literary classic. Given Kurosawa's appreciation of traditional Japanese stage acting, the acting of the players, particularly Yamada, draws heavily on the stylized techniques of the Noh theater. It was filmed in 1956 and released in January 1957 to a slightly less negative domestic response than had been the case with the director's previous film. Abroad, Throne of Blood, regardless of the liberties it takes with its source material, quickly earned a place among the most celebrated Shakespeare adaptations.Another adaptation of a classic European theatrical work followed almost immediately, with production of The Lower Depths, based on a play by Maxim Gorky, taking place in May and June 1957. In contrast to the Shakespearean sweep of Throne of Blood, The Lower Depths was shot on only two confined sets, in order to emphasize the restricted nature of the characters' lives. Though faithful to the play, this adaptation of Russian material to a completely Japanese setting—in this case, the late Edo period—unlike his earlier The Idiot, was regarded as artistically successful. The film premiered in September 1957, receiving a mixed response similar to that of Throne of Blood. However, some critics rank it among the director's most underrated works.Kurosawa's three consecutive movies after Seven Samurai had not managed to capture Japanese audiences in the way that that film had. The mood of the director's work had been growing increasingly pessimistic and dark, with the possibility of redemption through personal responsibility now very much questioned, particularly in Throne of Blood and The Lower Depths. He recognized this, and deliberately aimed for a more light-hearted and entertaining film for his next production, while switching to the new widescreen format that had been gaining popularity in Japan. The resulting film, The Hidden Fortress, is an action-adventure comedy-drama about a medieval princess, her loyal general and two peasants who all need to travel through enemy lines in order to reach their home region. Released in December 1958, The Hidden Fortress became an enormous box office success in Japan and was warmly received by critics both in Japan and abroad. Today, the film is considered one of Kurosawa's most lightweight efforts, though it remains popular, not least because it is one of several major influences on George Lucas's 1977 space opera, Star Wars. ==== Birth of a company and Red Beard (1959–65) ==== Starting with Rashomon, Kurosawa's productions had become increasingly large in scope and so had the director's budgets. Toho, concerned about this development, suggested that he might help finance his own works, therefore making the studio's potential losses smaller, while in turn allowing himself more artistic freedom as co-producer. Kurosawa agreed, and the Kurosawa Production Company was established in April 1959, with Toho as majority shareholder.Despite risking his own money, Kurosawa chose a story that was more directly critical of the Japanese business and political elites than any previous work. The Bad Sleep Well, based on a script by Kurosawa's nephew Mike Inoue, is a revenge drama about a young man who is able to infiltrate the hierarchy of a corrupt Japanese company with the intention of exposing the men responsible for his father's death. Its theme proved topical: while the film was in production, mass demonstrations were held against the new U.S.–Japan Security treaty, which was seen by many Japanese, particularly the young, as threatening the country's democracy by giving too much power to corporations and politicians. The film opened in September 1960 to positive critical reaction and modest box office success. The 25-minute opening sequence depicting a corporate wedding reception is widely regarded as one of Kurosawa's most skillfully executed set pieces, but the remainder of the film is often perceived as disappointing by comparison. The movie has also been criticized for employing the conventional Kurosawan hero to combat a social evil that cannot be resolved through the actions of individuals, however courageous or cunning.Yojimbo (The Bodyguard), Kurosawa Production's second film, centers on a masterless samurai, Sanjuro, who strolls into a 19th-century town ruled by two opposing violent factions and provokes them into destroying each other. The director used this work to play with many genre conventions, particularly the Western, while at the same time offering an unprecedentedly (for the Japanese screen) graphic portrayal of violence. Some commentators have seen the Sanjuro character in this film as a fantasy figure who magically reverses the historical triumph of the corrupt merchant class over the samurai class. Featuring Tatsuya Nakadai in his first major role in a Kurosawa movie, and with innovative photography by Kazuo Miyagawa (who shot Rashomon) and Takao Saito, the film premiered in April 1961 and was a critically and commercially successful venture, earning more than any previous Kurosawa film. The movie and its blackly comic tone were also widely imitated abroad. Sergio Leone's A Fistful of Dollars was a virtual (unauthorized) scene-by-scene remake with Toho filing a lawsuit on Kurosawa's behalf and prevailing. Following the success of Yojimbo, Kurosawa found himself under pressure from Toho to create a sequel. Kurosawa turned to a script he had written before Yojimbo, reworking it to include the hero of his previous film. Sanjuro was the first of three Kurosawa films to be adapted from the work of the writer Shūgorō Yamamoto (the others would be Red Beard and Dodeskaden). It is lighter in tone and closer to a conventional period film than Yojimbo, though its story of a power struggle within a samurai clan is portrayed with strongly comic undertones. The film opened on January 1, 1962, quickly surpassing Yojimbo's box office success and garnering positive reviews.Kurosawa had meanwhile instructed Toho to purchase the film rights to King's Ransom, a novel about a kidnapping written by American author and screenwriter Evan Hunter, under his pseudonym of Ed McBain, as one of his 87th Precinct series of crime books. The director intended to create a work condemning kidnapping, which he considered one of the very worst crimes. The suspense film, titled High and Low, was shot during the latter half of 1962 and released in March 1963. It broke Kurosawa's box office record (the third film in a row to do so), became the highest grossing Japanese film of the year, and won glowing reviews. However, his triumph was somewhat tarnished when, ironically, the film was blamed for a wave of kidnappings which occurred in Japan about this time (he himself received kidnapping threats directed at his young daughter, Kazuko). High and Low is considered by many commentators to be among the director's strongest works.Kurosawa quickly moved on to his next project, Red Beard. Based on a short story collection by Shūgorō Yamamoto and incorporating elements from Dostoyevsky's novel The Insulted and Injured, it is a period film, set in a mid-nineteenth century clinic for the poor, in which Kurosawa's humanist themes receive perhaps their fullest statement. A conceited and materialistic, foreign-trained young doctor, Yasumoto, is forced to become an intern at the clinic under the stern tutelage of Doctor Niide, known as "Akahige" ("Red Beard"), played by Mifune. Although he resists Red Beard initially, Yasumoto comes to admire his wisdom and courage, and to perceive the patients at the clinic, whom he at first despised, as worthy of compassion and dignity.Yūzō Kayama, who plays Yasumoto, was an extremely popular film and music star at the time, particularly for his "Young Guy" (Wakadaishō) series of musical comedies, so signing him to appear in the film virtually guaranteed Kurosawa strong box-office. The shoot, the filmmaker's longest ever, lasted well over a year (after five months of pre-production), and wrapped in spring 1965, leaving the director, his crew and his actors exhausted. Red Beard premiered in April 1965, becoming the year's highest-grossing Japanese production and the third (and last) Kurosawa film to top the prestigious Kinema Jumpo yearly critics poll. It remains one of Kurosawa's best-known and most-loved works in his native country. Outside Japan, critics have been much more divided. Most commentators concede its technical merits and some praise it as among Kurosawa's best, while others insist that it lacks complexity and genuine narrative power, with still others claiming that it represents a retreat from the artist's previous commitment to social and political change.The film marked something of an end of an era for its creator. The director himself recognized this at the time of its release, telling critic Donald Richie that a cycle of some kind had just come to an end and that his future films and production methods would be different. His prediction proved quite accurate. Beginning in the late 1950s, television began increasingly to dominate the leisure time of the formerly large and loyal Japanese cinema audience. And as film company revenues dropped, so did their appetite for risk—particularly the risk represented by Kurosawa's costly production methods.Red Beard also marked the midway point, chronologically, in the artist's career. During his previous twenty-nine years in the film industry (which includes his five years as assistant director), he had directed twenty-three films, while during the remaining twenty-eight years, for many and complex reasons, he would complete only seven more. Also, for reasons never adequately explained, Red Beard would be his final film starring Toshiro Mifune. Yu Fujiki, an actor who worked on The Lower Depths, observed, regarding the closeness of the two men on the set, "Mr. Kurosawa's heart was in Mr. Mifune's body." Donald Richie has described the rapport between them as a unique "symbiosis". === Hollywood ambitions to last films (1966–1998) === ==== Hollywood detour (1966–68) ==== When Kurosawa's exclusive contract with Toho came to an end in 1966, the 56-year-old director was seriously contemplating change. Observing the troubled state of the domestic film industry, and having already received dozens of offers from abroad, the idea of working outside Japan appealed to him as never before.For his first foreign project, Kurosawa chose a story based on a Life magazine article. The Embassy Pictures action thriller, to be filmed in English and called simply Runaway Train, would have been his first in color. But the language barrier proved a major problem, and the English version of the screenplay was not even finished by the time filming was to begin in autumn 1966. The shoot, which required snow, was moved to autumn 1967, then canceled in 1968. Almost twenty years later, another foreigner working in Hollywood, Andrei Konchalovsky, would finally make Runaway Train, though from a script totally different from Kurosawa's.The director meanwhile had become involved in a much more ambitious Hollywood project. Tora! Tora! Tora!, produced by 20th Century Fox and Kurosawa Production, would be a portrayal of the Japanese attack on Pearl Harbor from both the American and the Japanese points-of-view, with Kurosawa helming the Japanese half and an English-speaking filmmaker directing the American half. He spent several months working on the script with Ryuzo Kikushima and Hideo Oguni, but very soon the project began to unravel. The director chosen to film the American sequences turned out not to be the prestigious English filmmaker David Lean, as the producers had led Kurosawa to believe, but the much less celebrated special effects expert, Richard Fleischer. The budget was also cut, and the screen time allocated for the Japanese segment would now be no longer than 90 minutes—a major problem, considering that Kurosawa's script ran over four hours. After numerous revisions with the direct involvement of Darryl Zanuck, a more or less finalized cut screenplay was agreed upon in May 1968. Shooting began in early December, but Kurosawa would last only a little over three weeks as director. He struggled to work with an unfamiliar crew and the requirements of a Hollywood production, while his working methods puzzled his American producers, who ultimately concluded that the director must be mentally ill. Kurosawa was examined at Kyoto University Hospital by a neuropsychologist, Dr. Murakami, whose diagnosis was forwarded to Darryl Zanuck and Richard Zanuck at Fox studios indicating a diagnosis of neurasthenia stating that, "He is suffering from disturbance of sleep, agitated with feelings of anxiety and in manic excitement caused by the above mentioned illness. It is necessary for him to have rest and medical treatment for more than two months." On Christmas Eve 1968, the Americans announced that Kurosawa had left the production due to "fatigue", effectively firing him. He was ultimately replaced, for the film's Japanese sequences, with two directors, Kinji Fukasaku and Toshio Masuda.Tora! Tora! Tora!, finally released to unenthusiastic reviews in September 1970, was, as Donald Richie put it, an "almost unmitigated tragedy" in Kurosawa's career. He had spent years of his life on a logistically nightmarish project to which he ultimately did not contribute a foot of film shot by himself. (He had his name removed from the credits, though the script used for the Japanese half was still his and his co-writers'.) He became estranged from his longtime collaborator, writer Ryuzo Kikushima, and never worked with him again. The project had inadvertently exposed corruption in his own production company (a situation reminiscent of his own movie, The Bad Sleep Well). His very sanity had been called into question. Worst of all, the Japanese film industry—and perhaps the man himself—began to suspect that he would never make another film. ==== A difficult decade (1969–77) ==== Knowing that his reputation was at stake following the much publicised Tora! Tora! Tora! debacle, Kurosawa moved quickly to a new project to prove he was still viable. To his aid came friends and famed directors Keisuke Kinoshita, Masaki Kobayashi and Kon Ichikawa, who together with Kurosawa established in July 1969 a production company called the Club of the Four Knights (Yonki no kai). Although the plan was for the four directors to create a film each, it has been suggested that the real motivation for the other three directors was to make it easier for Kurosawa to successfully complete a film, and therefore find his way back into the business.The first project proposed and worked on was a period film to be called Dora-Heita, but when this was deemed too expensive, attention shifted to Dodesukaden, an adaptation of yet another Shūgorō Yamamoto work, again about the poor and destitute. The film was shot quickly (by Kurosawa's standards) in about nine weeks, with Kurosawa determined to show he was still capable of working quickly and efficiently within a limited budget. For his first work in color, the dynamic editing and complex compositions of his earlier pictures were set aside, with the artist focusing on the creation of a bold, almost surreal palette of primary colors, in order to reveal the toxic environment in which the characters live. It was released in Japan in October 1970, but though a minor critical success, it was greeted with audience indifference. The picture lost money and caused the Club of the Four Knights to dissolve. Initial reception abroad was somewhat more favorable, but Dodesukaden has since been typically considered an interesting experiment not comparable to the director's best work.Unable to secure funding for further work and allegedly suffering from health problems, Kurosawa apparently reached the breaking point: on December 22, 1971, he slit his wrists and throat multiple times. The suicide attempt proved unsuccessful and the director's health recovered fairly quickly, with Kurosawa now taking refuge in domestic life, uncertain if he would ever direct another film.In early 1973, the Soviet studio Mosfilm approached the filmmaker to ask if he would be interested in working with them. Kurosawa proposed an adaptation of Russian explorer Vladimir Arsenyev's autobiographical work Dersu Uzala. The book, about a Goldi hunter who lives in harmony with nature until destroyed by encroaching civilization, was one that he had wanted to make since the 1930s. In December 1973, the 63-year-old Kurosawa set off for the Soviet Union with four of his closest aides, beginning a year-and-a-half stay in the country. Shooting began in May 1974 in Siberia, with filming in exceedingly harsh natural conditions proving very difficult and demanding. The picture wrapped in April 1975, with a thoroughly exhausted and homesick Kurosawa returning to Japan and his family in June. Dersu Uzala had its world premiere in Japan on August 2, 1975, and did well at the box office. While critical reception in Japan was muted, the film was better reviewed abroad, winning the Golden Prize at the 9th Moscow International Film Festival, as well as an Academy Award for Best Foreign Language Film. Today, critics remain divided over the film: some see it as an example of Kurosawa's alleged artistic decline, while others count it among his finest works.Although proposals for television projects were submitted to him, he had no interest in working outside the film world. Nevertheless, the hard-drinking director did agree to appear in a series of television ads for Suntory whiskey, which aired in 1976. While fearing that he might never be able to make another film, the director nevertheless continued working on various projects, writing scripts and creating detailed illustrations, intending to leave behind a visual record of his plans in case he would never be able to film his stories. ==== Two epics (1978–86) ==== In 1977, American director George Lucas released Star Wars, a wildly successful science fiction film influenced by Kurosawa's The Hidden Fortress, among other works. Lucas, like many other New Hollywood directors, revered Kurosawa and considered him a role model, and was shocked to discover that the Japanese filmmaker was unable to secure financing for any new work. The two met in San Francisco in July 1978 to discuss the project Kurosawa considered most financially viable: Kagemusha, the epic story of a thief hired as the double of a medieval Japanese lord of a great clan. Lucas, enthralled by the screenplay and Kurosawa's illustrations, leveraged his influence over 20th Century Fox to coerce the studio that had fired Kurosawa just ten years earlier to produce Kagemusha, then recruited fellow fan Francis Ford Coppola as co-producer.Production began the following April, with Kurosawa in high spirits. Shooting lasted from June 1979 through March 1980 and was plagued with problems, not the least of which was the firing of the original lead actor, Shintaro Katsu—creator of the very popular Zatoichi character—due to an incident in which the actor insisted, against the director's wishes, on videotaping his own performance. (He was replaced by Tatsuya Nakadai, in his first of two consecutive leading roles in a Kurosawa movie.) The film was completed only a few weeks behind schedule and opened in Tokyo in April 1980. It quickly became a massive hit in Japan. The film was also a critical and box office success abroad, winning the coveted Palme d'Or at the 1980 Cannes Film Festival in May, though some critics, then and now, have faulted the film for its alleged coldness. Kurosawa spent much of the rest of the year in Europe and America promoting Kagemusha, collecting awards and accolades, and exhibiting as art the drawings he had made to serve as storyboards for the film. The international success of Kagemusha allowed Kurosawa to proceed with his next project, Ran, another epic in a similar vein. The script, partly based on William Shakespeare's King Lear, depicted a ruthless, bloodthirsty daimyō (warlord), played by Tatsuya Nakadai, who, after foolishly banishing his one loyal son, surrenders his kingdom to his other two sons, who then betray him, thus plunging the entire kingdom into war. As Japanese studios still felt wary about producing another film that would rank among the most expensive ever made in the country, international help was again needed. This time it came from French producer Serge Silberman, who had produced Luis Buñuel's final movies. Filming did not begin until December 1983 and lasted more than a year.In January 1985, production of Ran was halted as Kurosawa's 64-year-old wife Yōko fell ill. She died on February 1. Kurosawa returned to finish his film and Ran premiered at the Tokyo Film Festival on 31 May, with a wide release the next day. The film was a moderate financial success in Japan, but a larger one abroad and, as he had done with Kagemusha, Kurosawa embarked on a trip to Europe and America, where he attended the film's premieres in September and October.Ran won several awards in Japan, but was not quite as honored there as many of the director's best films of the 1950s and 1960s had been. The film world was surprised, however, when Japan passed over the selection of Ran in favor of another film as its official entry to compete for an Oscar nomination in the Best Foreign Film category, which was ultimately rejected for competition at the 57th Academy Awards. Both the producer and Kurosawa himself attributed the failure to even submit Ran for competition to a misunderstanding: because of the Academy's arcane rules, no one was sure whether Ran qualified as a Japanese film, a French film (due to its financing), or both, so it was not submitted at all. In response to what at least appeared to be a blatant snub by his own countrymen, the director Sidney Lumet led a successful campaign to have Kurosawa receive an Oscar nomination for Best Director that year (Sydney Pollack ultimately won the award for directing Out of Africa). Ran's costume designer, Emi Wada, won the movie's only Oscar.Kagemusha and Ran, particularly the latter, are often considered to be among Kurosawa's finest works. After Ran's release, Kurosawa would point to it as his best film, a major change of attitude for the director who, when asked which of his works was his best, had always previously answered "my next one". ==== Final works and last years (1987–98) ==== For his next movie, Kurosawa chose a subject very different from any that he had ever filmed before. While some of his previous pictures (for example, Drunken Angel and Kagemusha) had included brief dream sequences, Dreams was to be entirely based upon the director's own dreams. Significantly, for the first time in over forty years, Kurosawa, for this deeply personal project, wrote the screenplay alone. Although its estimated budget was lower than the films immediately preceding it, Japanese studios were still unwilling to back one of his productions, so Kurosawa turned to another famous American fan, Steven Spielberg, who convinced Warner Bros. to buy the international rights to the completed film. This made it easier for Kurosawa's son, Hisao, as co-producer and soon-to-be head of Kurosawa Production, to negotiate a loan in Japan that would cover the film's production costs. Shooting took more than eight months to complete, and Dreams premiered at Cannes in May 1990 to a polite but muted reception, similar to the reaction the picture would generate elsewhere in the world. In 1990, he accepted the Academy Award for Lifetime Achievement. Kurosawa now turned to a more conventional story with Rhapsody in August—the director's first film fully produced in Japan since Dodeskaden over twenty years before—which explored the scars of the nuclear bombing which destroyed Nagasaki at the very end of World War II. It was adapted from a Kiyoko Murata novel, but the film's references to the Nagasaki bombing came from the director rather than from the book. This was his only movie to include a role for an American movie star: Richard Gere, who plays a small role as the nephew of the elderly heroine. Shooting took place in early 1991, with the film opening on 25 May that year to a largely negative critical reaction, especially in the United States, where the director was accused of promulgating naïvely anti-American sentiments, though Kurosawa rejected these accusations. Kurosawa wasted no time moving onto his next project: Madadayo, or Not Yet. Based on autobiographical essays by Hyakken Uchida, the film follows the life of a Japanese professor of German through the Second World War and beyond. The narrative centers on yearly birthday celebrations with his former students, during which the protagonist declares his unwillingness to die just yet—a theme that was becoming increasingly relevant for the film's 81-year-old creator. Filming began in February 1992 and wrapped by the end of September. Its release on April 17, 1993, was greeted by an even more disappointed reaction than had been the case with his two preceding works.Kurosawa nevertheless continued to work. He wrote the original screenplays The Sea is Watching in 1993 and After the Rain in 1995. While putting finishing touches on the latter work in 1995, Kurosawa slipped and broke the base of his spine. Following the accident, he would use a wheelchair for the rest of his life, putting an end to any hopes of him directing another film. His longtime wish—to die on the set while shooting a movie—was never to be fulfilled. After his accident, Kurosawa's health began to deteriorate. While his mind remained sharp and lively, his body was giving up, and for the last half-year of his life, the director was largely confined to bed, listening to music and watching television at home. On September 6, 1998, Kurosawa died of a stroke in Setagaya, Tokyo, at the age of 88. At the time of his death, Kurosawa had two children, his son Hisao Kurosawa who married Hiroko Hayashi and his daughter Kazuko Kurosawa who married Harayuki Kato, along with several grandchildren. One of his grandchildren, the actor Takayuki Kato and grandson by Kazuko, became a supporting actor in two films posthumously developed from screenplays written by Kurosawa which remained unproduced during his own lifetime, Takashi Koizumi's After the Rain (1999) and Kei Kumai's The Sea is Watching (2002). == Style and main themes == From the beginning, Kurosawa displayed a bold, dynamic style, strongly influenced by Western cinema yet quite distinct from it. Kurosawa was extensively involved with every aspect of film production. He was also a gifted screenwriter, and would usually work in close collaboration with his co-writers from the beginning of the development of a film to ensure a high-quality script, which he insisted was the absolute foundation of a good film. He frequently served as editor of his own films and was regarded by his production team as "the greatest editor in the world". Though it was common in the Japanese film industry of that time for established directors to assemble around them a team, or "-gumi", with people drawn from the same pool of creative technicians, crew members and actors working from film to film (for example, the director Hiroshi Inagaki, who worked at Toho during the same period as Kurosawa, had such a team), Kurosawa's team, known as the "Kurosawa-gumi" (Kurosawa group)—including, for example, the cinematographer Asakazu Nakai, the production assistant Teruyo Nogami and the actor Takashi Shimura—was remarkable for its loyalty to the director and the consistent quality of its work. Kurosawa's style is marked by a number of devices and techniques which Kurosawa introduced in his films over the decades. In his films of the 1940s and 1950s, Kurosawa frequently employs the "axial cut", in which the camera moves closer to, or further away from, the subject, not through the use of tracking shots or dissolves, but through a series of matched jump cuts. Another stylistic trait which scholars have pointed out is Kurosawa's tendency to "cut on motion": that is, to edit a sequence of a character or characters in motion so that an action is depicted in two or more separate shots, rather than one uninterrupted shot.A form of cinematic punctuation very strongly identified with Kurosawa is the wipe. This is an effect created through an optical printer, in which, when a scene ends, a line or bar appears to move across the screen, "wiping" away the image while simultaneously revealing the first image of the subsequent scene. As a transitional device, it is used as a substitute for the straight cut or the dissolve (though Kurosawa often used both of those devices as well). In his mature work, Kurosawa employed the wipe so frequently that it became a kind of signature. For example, one blogger has counted no fewer than 12 instances of the wipe in Drunken Angel. Kurosawa by all accounts always gave great attention to the soundtracks of his films, especially with an emphasis on sound-image counterpoint, in which the music or sound effects would ironically comment upon the image rather than merely reinforcing it. (Teruyo Nogami's memoir gives several such examples from Drunken Angel and Stray Dog.) He was also involved with several of Japan's outstanding contemporary composers, including Fumio Hayasaka (who died in 1955) and the internationally famous Tōru Takemitsu.Kurosawa employed a number of recurring major themes in his films. These include: (a) the master-disciple relationship between a usually older mentor and one or more novices, which often involves spiritual as well as technical mastery and self-mastery; (b) the heroic champion, the exceptional individual who emerges from the mass of people to produce something or right some injustice; (c) the depiction of extremes of weather as both dramatic devices and symbols of human passion; and (d) the recurrence of cycles of inexorable savage violence within history. According to Stephen Prince, the latter theme began with Throne of Blood (1957), and recurred in Kurosawa films of the 1980s. Mr. Prince calls this theme "the countertradition to the committed, heroic mode of Kurosawa's cinema". == Legacy == === Legacy of general criticism === Criticism of Kurosawa in his legacy has significantly followed a close parity between the main currents of domestic criticism his films received when they were released in Japan with the international reception his individual films received when released abroad during his lifetime. Since the early to mid-1950s, a number of critics from the French New Wave championed the films of the older Japanese master, Kenji Mizoguchi, at the expense of Kurosawa's work. New Wave critic-filmmaker Jacques Rivette, said: "You can compare only what is comparable and that which aims high enough ... [Mizoguchi] seems to be the only Japanese director who is completely Japanese and yet is also the only one that achieves a true universality, that of an individual." According to such French commentators, Mizoguchi seemed, of the two artists, the more authentically Japanese. But at least one film scholar has questioned the validity of this dichotomy between "Japanese" Mizoguchi and "Western" Kurosawa by pointing out that "Mizo" had been at least as much influenced by Western cinema and Western culture in general as Kurosawa had ever been, and that this awareness of foreign trends is reflected in his work.In Japan, there have been critics and other filmmakers who have accused Kurosawa's work of elitism, because of his focus on exceptional, heroic individuals and groups of men. In her DVD commentary on Seven Samurai, Joan Mellen maintains that certain shots of the samurai characters Kambei and Kyuzo, which as far as she is concerned reveal Kurosawa "privileging" these samurai, "support the argument voiced by several Japanese critics that Kurosawa was an elitist ... Kurosawa was hardly a progressive director, they argued, since his peasants could not discover among their own ranks leaders who might rescue the village ... Kurosawa defended himself against this charge in his interview with me. 'I wanted to say that after everything the peasants were the stronger, closely clinging to the earth ... It was the samurai who were weak because they were being blown by the winds of time.'"Owing to Kurosawa's popularity with European and American audiences from the early 1950s onward, he did not escape the charge of deliberately catering to the tastes of Westerners to achieve or maintain that popularity. Joan Mellen, recording the violently negative reaction (in the 1970s) of the left-wing director Nagisa Oshima to Kurosawa and his work, states: "That Kurosawa had brought Japanese film to a Western audience meant [to Oshima] that he must be pandering to Western values and politics." Kurosawa always strongly denied pandering to Western tastes: "He has never catered to a foreign audience" writes Audie Bock, "and has condemned those who do". === Reputation among filmmakers === Many celebrated directors have been influenced by Kurosawa and have expressed admiration for his work. The filmmakers cited below can be presented according to four categories: (a) those who, like Kurosawa himself, established international critical reputations in the 1950s and early 1960s; (b) the so-called "New Hollywood" directors, that is, American moviemakers who, for the most part, established their reputations in the early to mid-1970s; (c) other Asian directors; and (d) modern-day directors. The Swedish director Ingmar Bergman called his own film The Virgin Spring "touristic, a lousy imitation of Kurosawa", and added, "At that time my admiration for the Japanese cinema was at its height. I was almost a samurai myself!" In Italy, Federico Fellini in an interview declared the director "the greatest living example of all that an author of the cinema should be"—despite admitting to having seen only one of his films, Seven Samurai. In France, Roman Polanski in 1965 cited Kurosawa as one of his three favorite filmmakers (with Fellini and Orson Welles), singling out Seven Samurai, Throne of Blood and The Hidden Fortress for praise. The Italian director Bernardo Bertolucci considered the Japanese master's influence to be seminal: "Kurosawa's movies and La Dolce Vita of Fellini are the things that pushed me, sucked me into being a film director." German New Wave director Werner Herzog has cited Kurosawa as one of his greatest influences: "Of the filmmakers with whom I feel some kinship, Griffith ... Buñuel, Kurosawa and Eisenstein's Ivan the Terrible, all come to mind." When asked to list his favorite directors, Russian director Andrei Tarkovsky cited Kurosawa as one of his favorites and named Seven Samurai as one of his ten favorite films. According to his personal assistant Anthony Frewin, Stanley Kubrick "thought Kurosawa was one of the great film directors and followed him closely. In fact I cannot think of any other director he spoke so consistently and admiringly about. So, if Kubrick was cast away on a desert island and could only take a few films, what would they be? My money would be on The Battle of Algiers, Danton, Rashomon, Seven Samurai and Throne of Blood."Kurosawa's New Hollywood admirers have included Robert Altman, Francis Ford Coppola, Steven Spielberg, Martin Scorsese, George Lucas, and John Milius. In his early years while still a television director, Robert Altman stated that when he first saw Rashomon he was so impressed by its cinematographer's achievement of shooting several shots with the camera aimed directly at the sun—allegedly it was the first film in which this was done successfully—that he claims he was inspired the very next day to begin incorporating shots of the sun into his television work. It was Coppola who said of Kurosawa, "One thing that distinguishes [him] is that he didn't make one masterpiece or two masterpieces. He made, you know, eight masterpieces." Both Spielberg and Scorsese have praised the older man's role as teacher and role model, and Scorsese called him his sensei, using the Japanese term. Spielberg has declared, "I have learned more from him than from almost any other filmmaker on the face of the earth", while Scorsese remarked, "Let me say it simply: Akira Kurosawa was my master, and ... the master of so many other filmmakers over the years." Several of these moviemakers were also instrumental in helping Kurosawa obtain financing for his late films: Lucas and Coppola served as co-producers on Kagemusha, while the Spielberg name, lent to the 1990 production, Dreams, helped bring that picture to fruition.As the first Asian filmmaker to achieve international prominence, Kurosawa has naturally served as an inspiration for other Asian auteurs. Of Rashomon, the most famous director of India, Satyajit Ray, said: "The effect of the film on me [upon first seeing it in Calcutta in 1952] was electric. I saw it three times on consecutive days, and wondered each time if there was another film anywhere which gave such sustained and dazzling proof of a director's command over every aspect of film making." Other Asian admirers include the Japanese actor and director Takeshi Kitano, Hong Kong filmmaker John Woo, Japanese anime director Hayao Miyazaki and mainland Chinese director Zhang Yimou, who called Kurosawa "the quintessential Asian director".Even today, Kurosawa continues to inspire and influence contemporary filmmakers. Alexander Payne spent the early part of his career watching Kurosawa's films, most notably Seven Samurai and Ikiru. Guillermo del Toro referred to Kurosawa "one of the essential masters", citing Throne of Blood, High and Low and Ran as among his favorite films. Kathryn Bigelow praised Kurosawa as one of "high-impact filmmakers" who can create emotionally invested characters. J.J. Abrams says he drew from Kurosawa while making Star Wars: the Force Awakens. At the age of 19, Alejandro González Iñárritu remembers being spellbound when he first saw Ikiru and praises Kurosawa as "one of the first storytelling geniuses who began to change the narrative structure of films." When Spike Lee posted a list of 87 films every aspiring director should see, he included three Kurosawa movies: Rashomon, Yojimbo and Ran. === Posthumous screenplays === Following Kurosawa's death, several posthumous works based on his unfilmed screenplays have been produced. After the Rain, directed by Takashi Koizumi, was released in 1999, and The Sea is Watching, directed by Kei Kumai, premiered in 2002. A script created by the Yonki no Kai ("Club of the Four Knights") (Kurosawa, Keisuke Kinoshita, Masaki Kobayashi, and Kon Ichikawa), around the time that Dodeskaden was made, finally was filmed and released (in 2000) as Dora-Heita, by the only surviving founding member of the club, Kon Ichikawa. Huayi Brothers Media and CKF Pictures in China announced in 2017 plans to produce a film of Kurosawa's posthumous screenplay of The Masque of the Black Death by Edgar Allan Poe for 2020. Patrick Frater writing for Variety magazine in May 2017 stated that another two unfinished films by Kurosawa were planned, with Silvering Spear to start filming in 2018. === Kurosawa Production Company === In September 2011, it was reported that remake rights to most of Kurosawa's movies and unproduced screenplays were assigned by the Akira Kurosawa 100 Project to the L.A.-based company Splendent. Splendent's chief Sakiko Yamada, stated that he aimed to "help contemporary film-makers introduce a new generation of moviegoers to these unforgettable stories".Kurosawa Production Co., established in 1959, continues to oversee many of the aspects of Kurosawa's legacy. The director's son, Hisao Kurosawa, is the current head of the company. Its American subsidiary, Kurosawa Enterprises, is located in Los Angeles. Rights to Kurosawa's works were then held by Kurosawa Production and the film studios under which he worked, most notably Toho. These rights were then assigned to the Akira Kurosawa 100 Project before being reassigned in 2011 to the L.A. based company Splendent. Kurosawa Production works closely with the Akira Kurosawa Foundation, established in December 2003 and also run by Hisao Kurosawa. The foundation organizes an annual short film competition and spearheads Kurosawa-related projects, including a recently shelved one to build a memorial museum for the director. === Film studios and awards === In 1981, the Kurosawa Film Studio was opened in Yokohama; two additional locations have since been launched in Japan. A large collection of archive material, including scanned screenplays, photos and news articles, has been made available through the Akira Kurosawa Digital Archive, a Japanese proprietary website maintained by Ryukoku University Digital Archives Research Center in collaboration with Kurosawa Production. Anaheim University's Akira Kurosawa School of Film was launched in spring 2009 with the backing of Kurosawa Production. It offers online programs in digital film making, with headquarters in Anaheim and a learning center in Tokyo.Two film awards have also been named in Kurosawa's honor. The Akira Kurosawa Award for Lifetime Achievement in Film Directing is awarded during the San Francisco International Film Festival, while the Akira Kurosawa Award is given during the Tokyo International Film Festival. In 1999 he was named "Asian of the Century" in the "Arts, Literature, and Culture" category by AsianWeek magazine and CNN, cited as "one of the [five] people who contributed most to the betterment of Asia in the past 100 years". In commemoration of the 100th anniversary of Kurosawa's birth in 2010, a project called AK100 was launched in 2008. The AK100 Project aims to "expose young people who are the representatives of the next generation, and all people everywhere, to the light and spirit of Akira Kurosawa and the wonderful world he created."Anaheim University in cooperation with the Kurosawa Family established the Anaheim University Akira Kurosawa School of Film to offer online and blended learning programs on Akira Kurosawa and filmmaking. The animated Wes Anderson film, Isle of Dogs, is partially inspired by Kurosawa's filming techniques. At the 64th Sydney Film Festival, there was a retrospective of Akira Kurosawa where films of his were screened to remember the great legacy he has created from his work. == Documentaries == A significant number of full-length and short documentaries concerning the life and films of Kurosawa were made during his lifetime and after his death. A.K. was filmed in 1985 and is a French documentary film directed by Chris Marker. Though it was filmed while Kurosawa was working on Ran, the film focuses more on Kurosawa's remote but polite personality than on the making of the film. The documentary is sometimes seen as being reflective of Marker's fascination with Japanese culture, which he also drew on for one of his best-known films, Sans Soleil. The film was screened in the Un Certain Regard section at the 1985 Cannes Film Festival. Other documentaries concerning Kurosawa's life and works produced posthumously include: Kurosawa: The Last Emperor (Alex Cox, 1999) A Message from Akira Kurosawa: For Beautiful Movies (Hisao Kurosawa, 2000) Kurosawa (Adam Low, 2001) Akira Kurosawa: It Is Wonderful to Create (Toho Masterworks, 2002) Akira Kurosawa: The Epic and the Intimate (2010) Kurosawa's Way (Catherine Cadou, 2011) == See also == List of creative works by Akira Kurosawa == References == === Notes === === Citations === === Sources === == Further reading == Buchanan, Judith (2005).

### Instruction: retrieve labels for this: Ancient Egypt was a civilization of ancient North Africa, concentrated along the lower reaches of the Nile River in the place that is now the country Egypt. Ancient Egyptian civilization followed prehistoric Egypt and coalesced around 3100 BC (according to conventional Egyptian chronology) with the political unification of Upper and Lower Egypt under Menes (often identified with Narmer). The history of ancient Egypt occurred as a series of stable kingdoms, separated by periods of relative instability known as Intermediate Periods: the Old Kingdom of the Early Bronze Age, the Middle Kingdom of the Middle Bronze Age and the New Kingdom of the Late Bronze Age. Egypt reached the pinnacle of its power in the New Kingdom, ruling much of Nubia and a sizable portion of the Near East, after which it entered a period of slow decline. During the course of its history Egypt was invaded or conquered by a number of foreign powers, including the Hyksos, the Libyans, the Nubians, the Assyrians, the Achaemenid Persians, and the Macedonians under the command of Alexander the Great. The Greek Ptolemaic Kingdom, formed in the aftermath of Alexander's death, ruled Egypt until 30 BC, when, under Cleopatra, it fell to the Roman Empire and became a Roman province.The success of ancient Egyptian civilization came partly from its ability to adapt to the conditions of the Nile River valley for agriculture. The predictable flooding and controlled irrigation of the fertile valley produced surplus crops, which supported a more dense population, and social development and culture. With resources to spare, the administration sponsored mineral exploitation of the valley and surrounding desert regions, the early development of an independent writing system, the organization of collective construction and agricultural projects, trade with surrounding regions, and a military intended to defeat foreign enemies and assert Egyptian dominance. Motivating and organizing these activities was a bureaucracy of elite scribes, religious leaders, and administrators under the control of a pharaoh, who ensured the cooperation and unity of the Egyptian people in the context of an elaborate system of religious beliefs.The many achievements of the ancient Egyptians include the quarrying, surveying and construction techniques that supported the building of monumental pyramids, temples, and obelisks; a system of mathematics, a practical and effective system of medicine, irrigation systems and agricultural production techniques, the first known planked boats, Egyptian faience and glass technology, new forms of literature, and the earliest known peace treaty, made with the Hittites. Ancient Egypt has left a lasting legacy. Its art and architecture were widely copied, and its antiquities carried off to far corners of the world. Its monumental ruins have inspired the imaginations of travelers and writers for centuries. A new-found respect for antiquities and excavations in the early modern period by Europeans and Egyptians led to the scientific investigation of Egyptian civilization and a greater appreciation of its cultural legacy. == History == The Nile has been the lifeline of its region for much of human history. The fertile floodplain of the Nile gave humans the opportunity to develop a settled agricultural economy and a more sophisticated, centralized society that became a cornerstone in the history of human civilization. Nomadic modern human hunter-gatherers began living in the Nile valley through the end of the Middle Pleistocene some 120,000 years ago. By the late Paleolithic period, the arid climate of Northern Africa became increasingly hot and dry, forcing the populations of the area to concentrate along the river region. === Predynastic period === In Predynastic and Early Dynastic times, the Egyptian climate was much less arid than it is today. Large regions of Egypt were covered in treed savanna and traversed by herds of grazing ungulates. Foliage and fauna were far more prolific in all environs and the Nile region supported large populations of waterfowl. Hunting would have been common for Egyptians, and this is also the period when many animals were first domesticated.By about 5500 BC, small tribes living in the Nile valley had developed into a series of cultures demonstrating firm control of agriculture and animal husbandry, and identifiable by their pottery and personal items, such as combs, bracelets, and beads. The largest of these early cultures in upper (Southern) Egypt was the Badari, which probably originated in the Western Desert; it was known for its high quality ceramics, stone tools, and its use of copper. The Badari was followed by the Amratian (Naqada I) and Gerzeh (Naqada II) cultures, which brought a number of technological improvements. As early as the Naqada I Period, predynastic Egyptians imported obsidian from Ethiopia, used to shape blades and other objects from flakes. In Naqada II times, early evidence exists of contact with the Near East, particularly Canaan and the Byblos coast. Over a period of about 1,000 years, the Naqada culture developed from a few small farming communities into a powerful civilization whose leaders were in complete control of the people and resources of the Nile valley. Establishing a power center at Nekhen (in Greek, Hierakonpolis), and later at Abydos, Naqada III leaders expanded their control of Egypt northwards along the Nile. They also traded with Nubia to the south, the oases of the western desert to the west, and the cultures of the eastern Mediterranean and Near East to the east.The Naqada culture manufactured a diverse selection of material goods, reflective of the increasing power and wealth of the elite, as well as societal personal-use items, which included combs, small statuary, painted pottery, high quality decorative stone vases, cosmetic palettes, and jewelry made of gold, lapis, and ivory. They also developed a ceramic glaze known as faience, which was used well into the Roman Period to decorate cups, amulets, and figurines. During the last predynastic phase, the Naqada culture began using written symbols that eventually were developed into a full system of hieroglyphs for writing the ancient Egyptian language. === Early Dynastic Period (c. 3050–2686 BC) === The Early Dynastic Period was approximately contemporary to the early Sumerian-Akkadian civilisation of Mesopotamia and of ancient Elam. The third-century BC Egyptian priest Manetho grouped the long line of pharaohs from Menes to his own time into 30 dynasties, a system still used today. He began his official history with the king named "Meni" (or Menes in Greek) who was believed to have united the two kingdoms of Upper and Lower Egypt.The transition to a unified state happened more gradually than ancient Egyptian writers represented, and there is no contemporary record of Menes. Some scholars now believe, however, that the mythical Menes may have been the pharaoh Narmer, who is depicted wearing royal regalia on the ceremonial Narmer Palette, in a symbolic act of unification. In the Early Dynastic Period, which began about 3000 BC, the first of the Dynastic pharaohs solidified control over lower Egypt by establishing a capital at Memphis, from which he could control the labour force and agriculture of the fertile delta region, as well as the lucrative and critical trade routes to the Levant. The increasing power and wealth of the pharaohs during the early dynastic period was reflected in their elaborate mastaba tombs and mortuary cult structures at Abydos, which were used to celebrate the deified pharaoh after his death. The strong institution of kingship developed by the pharaohs served to legitimize state control over the land, labour, and resources that were essential to the survival and growth of ancient Egyptian civilization. === Old Kingdom (2686–2181 BC) === Major advances in architecture, art, and technology were made during the Old Kingdom, fueled by the increased agricultural productivity and resulting population, made possible by a well-developed central administration. Some of ancient Egypt's crowning achievements, the Giza pyramids and Great Sphinx, were constructed during the Old Kingdom. Under the direction of the vizier, state officials collected taxes, coordinated irrigation projects to improve crop yield, drafted peasants to work on construction projects, and established a justice system to maintain peace and order. With the rising importance of central administration in Egypt a new class of educated scribes and officials arose who were granted estates by the pharaoh in payment for their services. Pharaohs also made land grants to their mortuary cults and local temples, to ensure that these institutions had the resources to worship the pharaoh after his death. Scholars believe that five centuries of these practices slowly eroded the economic vitality of Egypt, and that the economy could no longer afford to support a large centralized administration. As the power of the pharaohs diminished, regional governors called nomarchs began to challenge the supremacy of the office of pharaoh. This, coupled with severe droughts between 2200 and 2150 BC, is believed to have caused the country to enter the 140-year period of famine and strife known as the First Intermediate Period. === First Intermediate Period (2181–1991 BC) === After Egypt's central government collapsed at the end of the Old Kingdom, the administration could no longer support or stabilize the country's economy. Regional governors could not rely on the king for help in times of crisis, and the ensuing food shortages and political disputes escalated into famines and small-scale civil wars. Yet despite difficult problems, local leaders, owing no tribute to the pharaoh, used their new-found independence to establish a thriving culture in the provinces. Once in control of their own resources, the provinces became economically richer—which was demonstrated by larger and better burials among all social classes. In bursts of creativity, provincial artisans adopted and adapted cultural motifs formerly restricted to the royalty of the Old Kingdom, and scribes developed literary styles that expressed the optimism and originality of the period.Free from their loyalties to the pharaoh, local rulers began competing with each other for territorial control and political power. By 2160 BC, rulers in Herakleopolis controlled Lower Egypt in the north, while a rival clan based in Thebes, the Intef family, took control of Upper Egypt in the south. As the Intefs grew in power and expanded their control northward, a clash between the two rival dynasties became inevitable. Around 2055 BC the northern Theban forces under Nebhepetre Mentuhotep II finally defeated the Herakleopolitan rulers, reuniting the Two Lands. They inaugurated a period of economic and cultural renaissance known as the Middle Kingdom. === Middle Kingdom (2134–1690 BC) === The pharaohs of the Middle Kingdom restored the country's stability and prosperity, thereby stimulating a resurgence of art, literature, and monumental building projects. Mentuhotep II and his Eleventh Dynasty successors ruled from Thebes, but the vizier Amenemhat I, upon assuming the kingship at the beginning of the Twelfth Dynasty around 1985 BC, shifted the nation's capital to the city of Itjtawy, located in Faiyum. From Itjtawy, the pharaohs of the Twelfth Dynasty undertook a far-sighted land reclamation and irrigation scheme to increase agricultural output in the region. Moreover, the military reconquered territory in Nubia that was rich in quarries and gold mines, while laborers built a defensive structure in the Eastern Delta, called the "Walls-of-the-Ruler", to defend against foreign attack.With the pharaohs having secured the country militarily and politically and with vast agricultural and mineral wealth at their disposal, the nation's population, arts, and religion flourished. In contrast to elitist Old Kingdom attitudes towards the gods, the Middle Kingdom displayed an increase in expressions of personal piety. Middle Kingdom literature featured sophisticated themes and characters written in a confident, eloquent style. The relief and portrait sculpture of the period captured subtle, individual details that reached new heights of technical sophistication.The last great ruler of the Middle Kingdom, Amenemhat III, allowed Semitic-speaking Canaanite settlers from the Near East into the Delta region to provide a sufficient labour force for his especially active mining and building campaigns. These ambitious building and mining activities, however, combined with severe Nile floods later in his reign, strained the economy and precipitated the slow decline into the Second Intermediate Period during the later Thirteenth and Fourteenth dynasties. During this decline, the Canaanite settlers began to assume greater control of the Delta region, eventually coming to power in Egypt as the Hyksos. === Second Intermediate Period (1674–1549 BC) and the Hyksos === Around 1785 BC, as the power of the Middle Kingdom pharaohs weakened, a Western Asian people called the Hyksos, who had already settled in the Delta, seized control of Egypt and established their capital at Avaris, forcing the former central government to retreat to Thebes. The pharaoh was treated as a vassal and expected to pay tribute. The Hyksos ("foreign rulers") retained Egyptian models of government and identified as pharaohs, thereby integrating Egyptian elements into their culture. They and other invaders introduced new tools of warfare into Egypt, most notably the composite bow and the horse-drawn chariot.After retreating south, the native Theban kings found themselves trapped between the Canaanite Hyksos ruling the north and the Hyksos' Nubian allies, the Kushites, to the south. After years of vassalage, Thebes gathered enough strength to challenge the Hyksos in a conflict that lasted more than 30 years, until 1555 BC. The pharaohs Seqenenre Tao II and Kamose were ultimately able to defeat the Nubians to the south of Egypt, but failed to defeat the Hyksos. That task fell to Kamose's successor, Ahmose I, who successfully waged a series of campaigns that permanently eradicated the Hyksos' presence in Egypt. He established a new dynasty and, in the New Kingdom that followed, the military became a central priority for the pharaohs, who sought to expand Egypt's borders and attempted to gain mastery of the Near East. === New Kingdom (1549–1069 BC) === The New Kingdom pharaohs established a period of unprecedented prosperity by securing their borders and strengthening diplomatic ties with their neighbours, including the Mitanni Empire, Assyria, and Canaan. Military campaigns waged under Tuthmosis I and his grandson Tuthmosis III extended the influence of the pharaohs to the largest empire Egypt had ever seen. Between their reigns, Hatshepsut, a queen who established herself as pharaoh, launched many building projects, including restoration of temples damaged by the Hyksos, and sent trading expenditions to Punt and the Sinai. When Tuthmosis III died in 1425 BC, Egypt had an empire extending from Niya in north west Syria to the Fourth Cataract of the Nile in Nubia, cementing loyalties and opening access to critical imports such as bronze and wood.The New Kingdom pharaohs began a large-scale building campaign to promote the god Amun, whose growing cult was based in Karnak. They also constructed monuments to glorify their own achievements, both real and imagined. The Karnak temple is the largest Egyptian temple ever built.Around 1350 BC, the stability of the New Kingdom was threatened when Amenhotep IV ascended the throne and instituted a series of radical and chaotic reforms. Changing his name to Akhenaten, he touted the previously obscure sun deity Aten as the supreme deity, suppressed the worship of most other deities, and moved the capital to the new city of Akhetaten (modern-day Amarna). He was devoted to his new religion and artistic style. After his death, the cult of the Aten was quickly abandoned and the traditional religious order restored. The subsequent pharaohs, Tutankhamun, Ay, and Horemheb, worked to erase all mention of Akhenaten's heresy, now known as the Amarna Period. Around 1279 BC, Ramesses II, also known as Ramesses the Great, ascended the throne, and went on to build more temples, erect more statues and obelisks, and sire more children than any other pharaoh in history. A bold military leader, Ramesses II led his army against the Hittites in the Battle of Kadesh (in modern Syria) and, after fighting to a stalemate, finally agreed to the first recorded peace treaty, around 1258 BC.Egypt's wealth, however, made it a tempting target for invasion, particularly by the Libyan Berbers to the west, and the Sea Peoples, a conjectured confederation of seafarers from the Aegean Sea. Initially, the military was able to repel these invasions, but Egypt eventually lost control of its remaining territories in southern Canaan, much of it falling to the Assyrians. The effects of external threats were exacerbated by internal problems such as corruption, tomb robbery, and civil unrest. After regaining their power, the high priests at the temple of Amun in Thebes accumulated vast tracts of land and wealth, and their expanded power splintered the country during the Third Intermediate Period. === Third Intermediate Period (1069–653 BC) === Following the death of Ramesses XI in 1078 BC, Smendes assumed authority over the northern part of Egypt, ruling from the city of Tanis. The south was effectively controlled by the High Priests of Amun at Thebes, who recognized Smendes in name only. During this time, Libyans had been settling in the western delta, and chieftains of these settlers began increasing their autonomy. Libyan princes took control of the delta under Shoshenq I in 945 BC, founding the so-called Libyan or Bubastite dynasty that would rule for some 200 years. Shoshenq also gained control of southern Egypt by placing his family members in important priestly positions. Libyan control began to erode as a rival dynasty in the delta arose in Leontopolis, and Kushites threatened from the south. Around 727 BC the Kushite king Piye invaded northward, seizing control of Thebes and eventually the Delta.Egypt's far-reaching prestige declined considerably toward the end of the Third Intermediate Period. Its foreign allies had fallen under the Assyrian sphere of influence, and by 700 BC war between the two states became inevitable. Between 671 and 667 BC the Assyrians began their attack on Egypt. The reigns of both Taharqa and his successor, Tanutamun, were filled with constant conflict with the Assyrians, against whom Egypt enjoyed several victories. Ultimately, the Assyrians pushed the Kushites back into Nubia, occupied Memphis, and sacked the temples of Thebes. === Late Period (672–332 BC) === The Assyrians left control of Egypt to a series of vassals who became known as the Saite kings of the Twenty-Sixth Dynasty. By 653 BC, the Saite king Psamtik I was able to oust the Assyrians with the help of Greek mercenaries, who were recruited to form Egypt's first navy. Greek influence expanded greatly as the city of Naukratis became the home of Greeks in the delta. The Saite kings based in the new capital of Sais witnessed a brief but spirited resurgence in the economy and culture, but in 525 BC, the powerful Persians, led by Cambyses II, began their conquest of Egypt, eventually capturing the pharaoh Psamtik III at the battle of Pelusium. Cambyses II then assumed the formal title of pharaoh, but ruled Egypt from Iran, leaving Egypt under the control of a satrapy. A few successful revolts against the Persians marked the 5th century BC, but Egypt was never able to permanently overthrow the Persians.Following its annexation by Persia, Egypt was joined with Cyprus and Phoenicia in the sixth satrapy of the Achaemenid Persian Empire. This first period of Persian rule over Egypt, also known as the Twenty-Seventh dynasty, ended in 402 BC, when Egypt regained independence under a series of native dynasties. The last of these dynasties, the Thirtieth, proved to be the last native royal house of ancient Egypt, ending with the kingship of Nectanebo II. A brief restoration of Persian rule, sometimes known as the Thirty-First Dynasty, began in 343 BC, but shortly after, in 332 BC, the Persian ruler Mazaces handed Egypt over to Alexander the Great without a fight. === Ptolemaic period (332–30 BC) === In 332 BC, Alexander the Great conquered Egypt with little resistance from the Persians and was welcomed by the Egyptians as a deliverer. The administration established by Alexander's successors, the Macedonian Ptolemaic Kingdom, was based on an Egyptian model and based in the new capital city of Alexandria. The city showcased the power and prestige of Hellenistic rule, and became a seat of learning and culture, centered at the famous Library of Alexandria. The Lighthouse of Alexandria lit the way for the many ships that kept trade flowing through the city—as the Ptolemies made commerce and revenue-generating enterprises, such as papyrus manufacturing, their top priority.Hellenistic culture did not supplant native Egyptian culture, as the Ptolemies supported time-honored traditions in an effort to secure the loyalty of the populace. They built new temples in Egyptian style, supported traditional cults, and portrayed themselves as pharaohs. Some traditions merged, as Greek and Egyptian gods were syncretized into composite deities, such as Serapis, and classical Greek forms of sculpture influenced traditional Egyptian motifs. Despite their efforts to appease the Egyptians, the Ptolemies were challenged by native rebellion, bitter family rivalries, and the powerful mob of Alexandria that formed after the death of Ptolemy IV. In addition, as Rome relied more heavily on imports of grain from Egypt, the Romans took great interest in the political situation in the country. Continued Egyptian revolts, ambitious politicians, and powerful opponents from the Near East made this situation unstable, leading Rome to send forces to secure the country as a province of its empire. === Roman period (30 BC–641 AD) === Egypt became a province of the Roman Empire in 30 BC, following the defeat of Marc Antony and Ptolemaic Queen Cleopatra VII by Octavian (later Emperor Augustus) in the Battle of Actium. The Romans relied heavily on grain shipments from Egypt, and the Roman army, under the control of a prefect appointed by the Emperor, quelled rebellions, strictly enforced the collection of heavy taxes, and prevented attacks by bandits, which had become a notorious problem during the period. Alexandria became an increasingly important center on the trade route with the orient, as exotic luxuries were in high demand in Rome.Although the Romans had a more hostile attitude than the Greeks towards the Egyptians, some traditions such as mummification and worship of the traditional gods continued. The art of mummy portraiture flourished, and some Roman emperors had themselves depicted as pharaohs, though not to the extent that the Ptolemies had. The former lived outside Egypt and did not perform the ceremonial functions of Egyptian kingship. Local administration became Roman in style and closed to native Egyptians.From the mid-first century AD, Christianity took root in Egypt and it was originally seen as another cult that could be accepted. However, it was an uncompromising religion that sought to win converts from Egyptian Religion and Greco-Roman religion and threatened popular religious traditions. This led to the persecution of converts to Christianity, culminating in the great purges of Diocletian starting in 303, but eventually Christianity won out. In 391 the Christian Emperor Theodosius introduced legislation that banned pagan rites and closed temples. Alexandria became the scene of great anti-pagan riots with public and private religious imagery destroyed. As a consequence, Egypt's native religious culture was continually in decline. While the native population certainly continued to speak their language, the ability to read hieroglyphic writing slowly disappeared as the role of the Egyptian temple priests and priestesses diminished. The temples themselves were sometimes converted to churches or abandoned to the desert.In the fourth century, as the Roman Empire divided, Egypt found itself in the Eastern Empire with its capital at Constantinople. In the waning years of the Empire, Egypt fell to the Sassanid Persian army (618–628 AD), was recaptured by the Roman Emperor Heraclius (629–639 AD), and then was finally captured by Muslim Rashidun army in 639–641 AD, ending Roman rule. == Government and economy == === Administration and commerce === The pharaoh was the absolute monarch of the country and, at least in theory, wielded complete control of the land and its resources. The king was the supreme military commander and head of the government, who relied on a bureaucracy of officials to manage his affairs. In charge of the administration was his second in command, the vizier, who acted as the king's representative and coordinated land surveys, the treasury, building projects, the legal system, and the archives. At a regional level, the country was divided into as many as 42 administrative regions called nomes each governed by a nomarch, who was accountable to the vizier for his jurisdiction. The temples formed the backbone of the economy. Not only were they houses of worship, but were also responsible for collecting and storing the nation's wealth in a system of granaries and treasuries administered by overseers, who redistributed grain and goods.Much of the economy was centrally organized and strictly controlled. Although the ancient Egyptians did not use coinage until the Late period, they did use a type of money-barter system, with standard sacks of grain and the deben, a weight of roughly 91 grams (3 oz) of copper or silver, forming a common denominator. Workers were paid in grain; a simple laborer might earn 5½ sacks (200 kg or 400 lb) of grain per month, while a foreman might earn 7½ sacks (250 kg or 550 lb). Prices were fixed across the country and recorded in lists to facilitate trading; for example a shirt cost five copper deben, while a cow cost 140 deben. Grain could be traded for other goods, according to the fixed price list. During the fifth century BC coined money was introduced into Egypt from abroad. At first the coins were used as standardized pieces of precious metal rather than true money, but in the following centuries international traders came to rely on coinage. === Social status === Egyptian society was highly stratified, and social status was expressly displayed. Farmers made up the bulk of the population, but agricultural produce was owned directly by the state, temple, or noble family that owned the land. Farmers were also subject to a labor tax and were required to work on irrigation or construction projects in a corvée system. Artists and craftsmen were of higher status than farmers, but they were also under state control, working in the shops attached to the temples and paid directly from the state treasury. Scribes and officials formed the upper class in ancient Egypt, known as the "white kilt class" in reference to the bleached linen garments that served as a mark of their rank. The upper class prominently displayed their social status in art and literature. Below the nobility were the priests, physicians, and engineers with specialized training in their field. Slavery was known in ancient Egypt, but the extent and prevalence of its practice are unclear. The ancient Egyptians viewed men and women, including people from all social classes except slaves, as essentially equal under the law, and even the lowliest peasant was entitled to petition the vizier and his court for redress. Although slaves were mostly used as indentured servants, they were able to buy and sell their servitude, work their way to freedom or nobility, and were usually treated by doctors in the workplace. Both men and women had the right to own and sell property, make contracts, marry and divorce, receive inheritance, and pursue legal disputes in court. Married couples could own property jointly and protect themselves from divorce by agreeing to marriage contracts, which stipulated the financial obligations of the husband to his wife and children should the marriage end. Compared with their counterparts in ancient Greece, Rome, and even more modern places around the world, ancient Egyptian women had a greater range of personal choices and opportunities for achievement. Women such as Hatshepsut and Cleopatra VII even became pharaohs, while others wielded power as Divine Wives of Amun. Despite these freedoms, ancient Egyptian women did not often take part in official roles in the administration, served only secondary roles in the temples, and were not as likely to be as educated as men. === Legal system === The head of the legal system was officially the pharaoh, who was responsible for enacting laws, delivering justice, and maintaining law and order, a concept the ancient Egyptians referred to as Ma'at. Although no legal codes from ancient Egypt survive, court documents show that Egyptian law was based on a common-sense view of right and wrong that emphasized reaching agreements and resolving conflicts rather than strictly adhering to a complicated set of statutes. Local councils of elders, known as Kenbet in the New Kingdom, were responsible for ruling in court cases involving small claims and minor disputes. More serious cases involving murder, major land transactions, and tomb robbery were referred to the Great Kenbet, over which the vizier or pharaoh presided. Plaintiffs and defendants were expected to represent themselves and were required to swear an oath that they had told the truth. In some cases, the state took on both the role of prosecutor and judge, and it could torture the accused with beatings to obtain a confession and the names of any co-conspirators. Whether the charges were trivial or serious, court scribes documented the complaint, testimony, and verdict of the case for future reference.Punishment for minor crimes involved either imposition of fines, beatings, facial mutilation, or exile, depending on the severity of the offense. Serious crimes such as murder and tomb robbery were punished by execution, carried out by decapitation, drowning, or impaling the criminal on a stake. Punishment could also be extended to the criminal's family. Beginning in the New Kingdom, oracles played a major role in the legal system, dispensing justice in both civil and criminal cases. The procedure was to ask the god a "yes" or "no" question concerning the right or wrong of an issue. The god, carried by a number of priests, rendered judgment by choosing one or the other, moving forward or backward, or pointing to one of the answers written on a piece of papyrus or an ostracon. === Agriculture === A combination of favorable geographical features contributed to the success of ancient Egyptian culture, the most important of which was the rich fertile soil resulting from annual inundations of the Nile River. The ancient Egyptians were thus able to produce an abundance of food, allowing the population to devote more time and resources to cultural, technological, and artistic pursuits. Land management was crucial in ancient Egypt because taxes were assessed based on the amount of land a person owned.Farming in Egypt was dependent on the cycle of the Nile River. The Egyptians recognized three seasons: Akhet (flooding), Peret (planting), and Shemu (harvesting). The flooding season lasted from June to September, depositing on the river's banks a layer of mineral-rich silt ideal for growing crops. After the floodwaters had receded, the growing season lasted from October to February. Farmers plowed and planted seeds in the fields, which were irrigated with ditches and canals. Egypt received little rainfall, so farmers relied on the Nile to water their crops. From March to May, farmers used sickles to harvest their crops, which were then threshed with a flail to separate the straw from the grain. Winnowing removed the chaff from the grain, and the grain was then ground into flour, brewed to make beer, or stored for later use.The ancient Egyptians cultivated emmer and barley, and several other cereal grains, all of which were used to make the two main food staples of bread and beer. Flax plants, uprooted before they started flowering, were grown for the fibers of their stems. These fibers were split along their length and spun into thread, which was used to weave sheets of linen and to make clothing. Papyrus growing on the banks of the Nile River was used to make paper. Vegetables and fruits were grown in garden plots, close to habitations and on higher ground, and had to be watered by hand. Vegetables included leeks, garlic, melons, squashes, pulses, lettuce, and other crops, in addition to grapes that were made into wine. ==== Animals ==== The Egyptians believed that a balanced relationship between people and animals was an essential element of the cosmic order; thus humans, animals and plants were believed to be members of a single whole. Animals, both domesticated and wild, were therefore a critical source of spirituality, companionship, and sustenance to the ancient Egyptians. Cattle were the most important livestock; the administration collected taxes on livestock in regular censuses, and the size of a herd reflected the prestige and importance of the estate or temple that owned them. In addition to cattle, the ancient Egyptians kept sheep, goats, and pigs. Poultry, such as ducks, geese, and pigeons, were captured in nets and bred on farms, where they were force-fed with dough to fatten them. The Nile provided a plentiful source of fish. Bees were also domesticated from at least the Old Kingdom, and provided both honey and wax.The ancient Egyptians used donkeys and oxen as beasts of burden, and they were responsible for plowing the fields and trampling seed into the soil. The slaughter of a fattened ox was also a central part of an offering ritual. Horses were introduced by the Hyksos in the Second Intermediate Period. Camels, although known from the New Kingdom, were not used as beasts of burden until the Late Period. There is also evidence to suggest that elephants were briefly utilized in the Late Period but largely abandoned due to lack of grazing land. Dogs, cats, and monkeys were common family pets, while more exotic pets imported from the heart of Africa, such as Sub-Saharan African lions, were reserved for royalty. Herodotus observed that the Egyptians were the only people to keep their animals with them in their houses. During the Late Period, the worship of the gods in their animal form was extremely popular, such as the cat goddess Bastet and the ibis god Thoth, and these animals were bred in large numbers on farms for the purpose of ritual sacrifice. === Natural resources === Egypt is rich in building and decorative stone, copper and lead ores, gold, and semiprecious stones. These natural resources allowed the ancient Egyptians to build monuments, sculpt statues, make tools, and fashion jewelry. Embalmers used salts from the Wadi Natrun for mummification, which also provided the gypsum needed to make plaster. Ore-bearing rock formations were found in distant, inhospitable wadis in the eastern desert and the Sinai, requiring large, state-controlled expeditions to obtain natural resources found there. There were extensive gold mines in Nubia, and one of the first maps known is of a gold mine in this region. The Wadi Hammamat was a notable source of granite, greywacke, and gold. Flint was the first mineral collected and used to make tools, and flint handaxes are the earliest pieces of evidence of habitation in the Nile valley. Nodules of the mineral were carefully flaked to make blades and arrowheads of moderate hardness and durability even after copper was adopted for this purpose. Ancient Egyptians were among the first to use minerals such as sulfur as cosmetic substances.The Egyptians worked deposits of the lead ore galena at Gebel Rosas to make net sinkers, plumb bobs, and small figurines. Copper was the most important metal for toolmaking in ancient Egypt and was smelted in furnaces from malachite ore mined in the Sinai. Workers collected gold by washing the nuggets out of sediment in alluvial deposits, or by the more labor-intensive process of grinding and washing gold-bearing quartzite. Iron deposits found in upper Egypt were utilized in the Late Period. High-quality building stones were abundant in Egypt; the ancient Egyptians quarried limestone all along the Nile valley, granite from Aswan, and basalt and sandstone from the wadis of the eastern desert. Deposits of decorative stones such as porphyry, greywacke, alabaster, and carnelian dotted the eastern desert and were collected even before the First Dynasty. In the Ptolemaic and Roman Periods, miners worked deposits of emeralds in Wadi Sikait and amethyst in Wadi el-Hudi. === Trade === The ancient Egyptians engaged in trade with their foreign neighbors to obtain rare, exotic goods not found in Egypt. In the Predynastic Period, they established trade with Nubia to obtain gold and incense. They also established trade with Palestine, as evidenced by Palestinian-style oil jugs found in the burials of the First Dynasty pharaohs. An Egyptian colony stationed in southern Canaan dates to slightly before the First Dynasty. Narmer had Egyptian pottery produced in Canaan and exported back to Egypt.By the Second Dynasty at latest, ancient Egyptian trade with Byblos yielded a critical source of quality timber not found in Egypt. By the Fifth Dynasty, trade with Punt provided gold, aromatic resins, ebony, ivory, and wild animals such as monkeys and baboons. Egypt relied on trade with Anatolia for essential quantities of tin as well as supplementary supplies of copper, both metals being necessary for the manufacture of bronze. The ancient Egyptians prized the blue stone lapis lazuli, which had to be imported from far-away Afghanistan. Egypt's Mediterranean trade partners also included Greece and Crete, which provided, among other goods, supplies of olive oil. In exchange for its luxury imports and raw materials, Egypt mainly exported grain, gold, linen, and papyrus, in addition to other finished goods including glass and stone objects. == Language == === Historical development === The Egyptian language is a northern Afro-Asiatic language closely related to the Berber and Semitic languages. It has the second longest known history of any language (after Sumerian), having been written from c. 3200 BC to the Middle Ages and remaining as a spoken language for longer. The phases of ancient Egyptian are Old Egyptian, Middle Egyptian (Classical Egyptian), Late Egyptian, Demotic and Coptic. Egyptian writings do not show dialect differences before Coptic, but it was probably spoken in regional dialects around Memphis and later Thebes.Ancient Egyptian was a synthetic language, but it became more analytic later on. Late Egyptian developed prefixal definite and indefinite articles, which replaced the older inflectional suffixes. There was a change from the older verb–subject–object word order to subject–verb–object. The Egyptian hieroglyphic, hieratic, and demotic scripts were eventually replaced by the more phonetic Coptic alphabet. Coptic is still used in the liturgy of the Egyptian Orthodox Church, and traces of it are found in modern Egyptian Arabic. === Sounds and grammar === Ancient Egyptian has 25 consonants similar to those of other Afro-Asiatic languages. These include pharyngeal and emphatic consonants, voiced and voiceless stops, voiceless fricatives and voiced and voiceless affricates. It has three long and three short vowels, which expanded in Late Egyptian to about nine. The basic word in Egyptian, similar to Semitic and Berber, is a triliteral or biliteral root of consonants and semiconsonants. Suffixes are added to form words. The verb conjugation corresponds to the person. For example, the triconsonantal skeleton S-Ḏ-M is the semantic core of the word 'hear'; its basic conjugation is sḏm, 'he hears'. If the subject is a noun, suffixes are not added to the verb: sḏm ḥmt, 'the woman hears'. Adjectives are derived from nouns through a process that Egyptologists call nisbation because of its similarity with Arabic. The word order is predicate–subject in verbal and adjectival sentences, and subject–predicate in nominal and adverbial sentences. The subject can be moved to the beginning of sentences if it is long and is followed by a resumptive pronoun. Verbs and nouns are negated by the particle n, but nn is used for adverbial and adjectival sentences. Stress falls on the ultimate or penultimate syllable, which can be open (CV) or closed (CVC). === Writing === Hieroglyphic writing dates from c. 3000 BC, and is composed of hundreds of symbols. A hieroglyph can represent a word, a sound, or a silent determinative; and the same symbol can serve different purposes in different contexts. Hieroglyphs were a formal script, used on stone monuments and in tombs, that could be as detailed as individual works of art. In day-to-day writing, scribes used a cursive form of writing, called hieratic, which was quicker and easier. While formal hieroglyphs may be read in rows or columns in either direction (though typically written from right to left), hieratic was always written from right to left, usually in horizontal rows. A new form of writing, Demotic, became the prevalent writing style, and it is this form of writing—along with formal hieroglyphs—that accompany the Greek text on the Rosetta Stone.Around the first century AD, the Coptic alphabet started to be used alongside the Demotic script. Coptic is a modified Greek alphabet with the addition of some Demotic signs. Although formal hieroglyphs were used in a ceremonial role until the fourth century, towards the end only a small handful of priests could still read them. As the traditional religious establishments were disbanded, knowledge of hieroglyphic writing was mostly lost. Attempts to decipher them date to the Byzantine and Islamic periods in Egypt, but only in the 1820s, after the discovery of the Rosetta Stone and years of research by Thomas Young and Jean-François Champollion, were hieroglyphs substantially deciphered. === Literature === Writing first appeared in association with kingship on labels and tags for items found in royal tombs. It was primarily an occupation of the scribes, who worked out of the Per Ankh institution or the House of Life. The latter comprised offices, libraries (called House of Books), laboratories and observatories. Some of the best-known pieces of ancient Egyptian literature, such as the Pyramid and Coffin Texts, were written in Classical Egyptian, which continued to be the language of writing until about 1300 BC. Late Egyptian was spoken from the New Kingdom onward and is represented in Ramesside administrative documents, love poetry and tales, as well as in Demotic and Coptic texts. During this period, the tradition of writing had evolved into the tomb autobiography, such as those of Harkhuf and Weni. The genre known as Sebayt ("instructions") was developed to communicate teachings and guidance from famous nobles; the Ipuwer papyrus, a poem of lamentations describing natural disasters and social upheaval, is a famous example. The Story of Sinuhe, written in Middle Egyptian, might be the classic of Egyptian literature. Also written at this time was the Westcar Papyrus, a set of stories told to Khufu by his sons relating the marvels performed by priests. The Instruction of Amenemope is considered a masterpiece of Near Eastern literature. Towards the end of the New Kingdom, the vernacular language was more often employed to write popular pieces like the Story of Wenamun and the Instruction of Any. The former tells the story of a noble who is robbed on his way to buy cedar from Lebanon and of his struggle to return to Egypt. From about 700 BC, narrative stories and instructions, such as the popular Instructions of Onchsheshonqy, as well as personal and business documents were written in the demotic script and phase of Egyptian. Many stories written in demotic during the Greco-Roman period were set in previous historical eras, when Egypt was an independent nation ruled by great pharaohs such as Ramesses II. == Culture == === Daily life === Most ancient Egyptians were farmers tied to the land. Their dwellings were restricted to immediate family members, and were constructed of mud-brick designed to remain cool in the heat of the day. Each home had a kitchen with an open roof, which contained a grindstone for milling grain and a small oven for baking the bread. Walls were painted white and could be covered with dyed linen wall hangings. Floors were covered with reed mats, while wooden stools, beds raised from the floor and individual tables comprised the furniture.The ancient Egyptians placed a great value on hygiene and appearance. Most bathed in the Nile and used a pasty soap made from animal fat and chalk. Men shaved their entire bodies for cleanliness; perfumes and aromatic ointments covered bad odors and soothed skin. Clothing was made from simple linen sheets that were bleached white, and both men and women of the upper classes wore wigs, jewelry, and cosmetics. Children went without clothing until maturity, at about age 12, and at this age males were circumcised and had their heads shaved. Mothers were responsible for taking care of the children, while the father provided the family's income. Music and dance were popular entertainments for those who could afford them. Early instruments included flutes and harps, while instruments similar to trumpets, oboes, and pipes developed later and became popular. In the New Kingdom, the Egyptians played on bells, cymbals, tambourines, drums, and imported lutes and lyres from Asia. The sistrum was a rattle-like musical instrument that was especially important in religious ceremonies. The ancient Egyptians enjoyed a variety of leisure activities, including games and music. Senet, a board game where pieces moved according to random chance, was particularly popular from the earliest times; another similar game was mehen, which had a circular gaming board. Juggling and ball games were popular with children, and wrestling is also documented in a tomb at Beni Hasan. The wealthy members of ancient Egyptian society enjoyed hunting and boating as well. The excavation of the workers village of Deir el-Medina has resulted in one of the most thoroughly documented accounts of community life in the ancient world, which spans almost four hundred years. There is no comparable site in which the organization, social interactions, working and living conditions of a community have been studied in such detail. === Cuisine === Egyptian cuisine remained remarkably stable over time; indeed, the cuisine of modern Egypt retains some striking similarities to the cuisine of the ancients. The staple diet consisted of bread and beer, supplemented with vegetables such as onions and garlic, and fruit such as dates and figs. Wine and meat were enjoyed by all on feast days while the upper classes indulged on a more regular basis. Fish, meat, and fowl could be salted or dried, and could be cooked in stews or roasted on a grill. === Architecture === The architecture of ancient Egypt includes some of the most famous structures in the world: the Great Pyramids of Giza and the temples at Thebes. Building projects were organized and funded by the state for religious and commemorative purposes, but also to reinforce the wide-ranging power of the pharaoh. The ancient Egyptians were skilled builders; using only simple but effective tools and sighting instruments, architects could build large stone structures with great accuracy and precision that is still envied today.The domestic dwellings of elite and ordinary Egyptians alike were constructed from perishable materials such as mud bricks and wood, and have not survived. Peasants lived in simple homes, while the palaces of the elite and the pharaoh were more elaborate structures. A few surviving New Kingdom palaces, such as those in Malkata and Amarna, show richly decorated walls and floors with scenes of people, birds, water pools, deities and geometric designs. Important structures such as temples and tombs that were intended to last forever were constructed of stone instead of mud bricks. The architectural elements used in the world's first large-scale stone building, Djoser's mortuary complex, include post and lintel supports in the papyrus and lotus motif. The earliest preserved ancient Egyptian temples, such as those at Giza, consist of single, enclosed halls with roof slabs supported by columns. In the New Kingdom, architects added the pylon, the open courtyard, and the enclosed hypostyle hall to the front of the temple's sanctuary, a style that was standard until the Greco-Roman period. The earliest and most popular tomb architecture in the Old Kingdom was the mastaba, a flat-roofed rectangular structure of mudbrick or stone built over an underground burial chamber. The step pyramid of Djoser is a series of stone mastabas stacked on top of each other. Pyramids were built during the Old and Middle Kingdoms, but most later rulers abandoned them in favor of less conspicuous rock-cut tombs. The use of the pyramid form continued in private tomb chapels of the New Kingdom and in the royal pyramids of Nubia. === Art === The ancient Egyptians produced art to serve functional purposes. For over 3500 years, artists adhered to artistic forms and iconography that were developed during the Old Kingdom, following a strict set of principles that resisted foreign influence and internal change. These artistic standards—simple lines, shapes, and flat areas of color combined with the characteristic flat projection of figures with no indication of spatial depth—created a sense of order and balance within a composition. Images and text were intimately interwoven on tomb and temple walls, coffins, stelae, and even statues. The Narmer Palette, for example, displays figures that can also be read as hieroglyphs. Because of the rigid rules that governed its highly stylized and symbolic appearance, ancient Egyptian art served its political and religious purposes with precision and clarity.Ancient Egyptian artisans used stone as a medium for carving statues and fine reliefs, but used wood as a cheap and easily carved substitute. Paints were obtained from minerals such as iron ores (red and yellow ochres), copper ores (blue and green), soot or charcoal (black), and limestone (white). Paints could be mixed with gum arabic as a binder and pressed into cakes, which could be moistened with water when needed.Pharaohs used reliefs to record victories in battle, royal decrees, and religious scenes. Common citizens had access to pieces of funerary art, such as shabti statues and books of the dead, which they believed would protect them in the afterlife. During the Middle Kingdom, wooden or clay models depicting scenes from everyday life became popular additions to the tomb. In an attempt to duplicate the activities of the living in the afterlife, these models show laborers, houses, boats, and even military formations that are scale representations of the ideal ancient Egyptian afterlife.Despite the homogeneity of ancient Egyptian art, the styles of particular times and places sometimes reflected changing cultural or political attitudes. After the invasion of the Hyksos in the Second Intermediate Period, Minoan-style frescoes were found in Avaris. The most striking example of a politically driven change in artistic forms comes from the Amarna period, where figures were radically altered to conform to Akhenaten's revolutionary religious ideas. This style, known as Amarna art, was quickly abandoned after Akhenaten's death and replaced by the traditional forms. === Religious beliefs === Beliefs in the divine and in the afterlife were ingrained in ancient Egyptian civilization from its inception; pharaonic rule was based on the divine right of kings. The Egyptian pantheon was populated by gods who had supernatural powers and were called on for help or protection. However, the gods were not always viewed as benevolent, and Egyptians believed they had to be appeased with offerings and prayers. The structure of this pantheon changed continually as new deities were promoted in the hierarchy, but priests made no effort to organize the diverse and sometimes conflicting myths and stories into a coherent system. These various conceptions of divinity were not considered contradictory but rather layers in the multiple facets of reality. Gods were worshiped in cult temples administered by priests acting on the king's behalf. At the center of the temple was the cult statue in a shrine. Temples were not places of public worship or congregation, and only on select feast days and celebrations was a shrine carrying the statue of the god brought out for public worship. Normally, the god's domain was sealed off from the outside world and was only accessible to temple officials. Common citizens could worship private statues in their homes, and amulets offered protection against the forces of chaos. After the New Kingdom, the pharaoh's role as a spiritual intermediary was de-emphasized as religious customs shifted to direct worship of the gods. As a result, priests developed a system of oracles to communicate the will of the gods directly to the people.The Egyptians believed that every human being was composed of physical and spiritual parts or aspects. In addition to the body, each person had a šwt (shadow), a ba (personality or soul), a ka (life-force), and a name. The heart, rather than the brain, was considered the seat of thoughts and emotions. After death, the spiritual aspects were released from the body and could move at will, but they required the physical remains (or a substitute, such as a statue) as a permanent home. The ultimate goal of the deceased was to rejoin his ka and ba and become one of the "blessed dead", living on as an akh, or "effective one". For this to happen, the deceased had to be judged worthy in a trial, in which the heart was weighed against a "feather of truth". If deemed worthy, the deceased could continue their existence on earth in spiritual form. === Burial customs === The ancient Egyptians maintained an elaborate set of burial customs that they believed were necessary to ensure immortality after death. These customs involved preserving the body by mummification, performing burial ceremonies, and interring with the body goods the deceased would use in the afterlife. Before the Old Kingdom, bodies buried in desert pits were naturally preserved by desiccation. The arid, desert conditions were a boon throughout the history of ancient Egypt for burials of the poor, who could not afford the elaborate burial preparations available to the elite. Wealthier Egyptians began to bury their dead in stone tombs and use artificial mummification, which involved removing the internal organs, wrapping the body in linen, and burying it in a rectangular stone sarcophagus or wooden coffin. Beginning in the Fourth Dynasty, some parts were preserved separately in canopic jars.By the New Kingdom, the ancient Egyptians had perfected the art of mummification; the best technique took 70 days and involved removing the internal organs, removing the brain through the nose, and desiccating the body in a mixture of salts called natron. The body was then wrapped in linen with protective amulets inserted between layers and placed in a decorated anthropoid coffin. Mummies of the Late Period were also placed in painted cartonnage mummy cases. Actual preservation practices declined during the Ptolemaic and Roman eras, while greater emphasis was placed on the outer appearance of the mummy, which was decorated.Wealthy Egyptians were buried with larger quantities of luxury items, but all burials, regardless of social status, included goods for the deceased. Funerary texts were often included in the grave, and, beginning in the New Kingdom, so were shabti statues that were believed to perform manual labor for them in the afterlife. Rituals in which the deceased was magically re-animated accompanied burials. After burial, living relatives were expected to occasionally bring food to the tomb and recite prayers on behalf of the deceased. == Military == The ancient Egyptian military was responsible for defending Egypt against foreign invasion, and for maintaining Egypt's domination in the ancient Near East. The military protected mining expeditions to the Sinai during the Old Kingdom and fought civil wars during the First and Second Intermediate Periods. The military was responsible for maintaining fortifications along important trade routes, such as those found at the city of Buhen on the way to Nubia. Forts also were constructed to serve as military bases, such as the fortress at Sile, which was a base of operations for expeditions to the Levant. In the New Kingdom, a series of pharaohs used the standing Egyptian army to attack and conquer Kush and parts of the Levant.Typical military equipment included bows and arrows, spears, and round-topped shields made by stretching animal skin over a wooden frame. In the New Kingdom, the military began using chariots that had earlier been introduced by the Hyksos invaders. Weapons and armor continued to improve after the adoption of bronze: shields were now made from solid wood with a bronze buckle, spears were tipped with a bronze point, and the Khopesh was adopted from Asiatic soldiers. The pharaoh was usually depicted in art and literature riding at the head of the army; it has been suggested that at least a few pharaohs, such as Seqenenre Tao II and his sons, did do so. However, it has also been argued that "kings of this period did not personally act as frontline war leaders, fighting alongside their troops." Soldiers were recruited from the general population, but during, and especially after, the New Kingdom, mercenaries from Nubia, Kush, and Libya were hired to fight for Egypt. == Technology, medicine, and mathematics == === Technology === In technology, medicine, and mathematics, ancient Egypt achieved a relatively high standard of productivity and sophistication. Traditional empiricism, as evidenced by the Edwin Smith and Ebers papyri (c. 1600 BC), is first credited to Egypt. The Egyptians created their own alphabet and decimal system. === Faience and glass === Even before the Old Kingdom, the ancient Egyptians had developed a glassy material known as faience, which they treated as a type of artificial semi-precious stone. Faience is a non-clay ceramic made of silica, small amounts of lime and soda, and a colorant, typically copper. The material was used to make beads, tiles, figurines, and small wares. Several methods can be used to create faience, but typically production involved application of the powdered materials in the form of a paste over a clay core, which was then fired. By a related technique, the ancient Egyptians produced a pigment known as Egyptian Blue, also called blue frit, which is produced by fusing (or sintering) silica, copper, lime, and an alkali such as natron. The product can be ground up and used as a pigment.The ancient Egyptians could fabricate a wide variety of objects from glass with great skill, but it is not clear whether they developed the process independently. It is also unclear whether they made their own raw glass or merely imported pre-made ingots, which they melted and finished. However, they did have technical expertise in making objects, as well as adding trace elements to control the color of the finished glass. A range of colors could be produced, including yellow, red, green, blue, purple, and white, and the glass could be made either transparent or opaque. === Medicine === The medical problems of the ancient Egyptians stemmed directly from their environment. Living and working close to the Nile brought hazards from malaria and debilitating schistosomiasis parasites, which caused liver and intestinal damage. Dangerous wildlife such as crocodiles and hippos were also a common threat. The lifelong labors of farming and building put stress on the spine and joints, and traumatic injuries from construction and warfare all took a significant toll on the body. The grit and sand from stone-ground flour abraded teeth, leaving them susceptible to abscesses (though caries were rare).The diets of the wealthy were rich in sugars, which promoted periodontal disease. Despite the flattering physiques portrayed on tomb walls, the overweight mummies of many of the upper class show the effects of a life of overindulgence. Adult life expectancy was about 35 for men and 30 for women, but reaching adulthood was difficult as about one-third of the population died in infancy.Ancient Egyptian physicians were renowned in the ancient Near East for their healing skills, and some, such as Imhotep, remained famous long after their deaths. Herodotus remarked that there was a high degree of specialization among Egyptian physicians, with some treating only the head or the stomach, while others were eye-doctors and dentists. Training of physicians took place at the Per Ankh or "House of Life" institution, most notably those headquartered in Per-Bastet during the New Kingdom and at Abydos and Saïs in the Late period. Medical papyri show empirical knowledge of anatomy, injuries, and practical treatments.Wounds were treated by bandaging with raw meat, white linen, sutures, nets, pads, and swabs soaked with honey to prevent infection, while opium thyme and belladona were used to relieve pain. The earliest records of burn treatment describe burn dressings that use the milk from mothers of male babies. Prayers were made to the goddess Isis. Moldy bread, honey and copper salts were also used to prevent infection from dirt in burns. Garlic and onions were used regularly to promote good health and were thought to relieve asthma symptoms. Ancient Egyptian surgeons stitched wounds, set broken bones, and amputated diseased limbs, but they recognized that some injuries were so serious that they could only make the patient comfortable until death occurred. === Maritime technology === Early Egyptians knew how to assemble planks of wood into a ship hull and had mastered advanced forms of shipbuilding as early as 3000 BC. The Archaeological Institute of America reports that the oldest planked ships known are the Abydos boats. A group of 14 discovered ships in Abydos were constructed of wooden planks "sewn" together. Discovered by Egyptologist David O'Connor of New York University, woven straps were found to have been used to lash the planks together, and reeds or grass stuffed between the planks helped to seal the seams. Because the ships are all buried together and near a mortuary belonging to Pharaoh Khasekhemwy, originally they were all thought to have belonged to him, but one of the 14 ships dates to 3000 BC, and the associated pottery jars buried with the vessels also suggest earlier dating. The ship dating to 3000 BC was 75 feet (23 m) long and is now thought to perhaps have belonged to an earlier pharaoh, perhaps one as early as Hor-Aha.Early Egyptians also knew how to assemble planks of wood with treenails to fasten them together, using pitch for caulking the seams. The "Khufu ship", a 43.6-metre (143 ft) vessel sealed into a pit in the Giza pyramid complex at the foot of the Great Pyramid of Giza in the Fourth Dynasty around 2500 BC, is a full-size surviving example that may have filled the symbolic function of a solar barque. Early Egyptians also knew how to fasten the planks of this ship together with mortise and tenon joints. Large seagoing ships are known to have been heavily used by the Egyptians in their trade with the city states of the eastern Mediterranean, especially Byblos (on the coast of modern-day Lebanon), and in several expeditions down the Red Sea to the Land of Punt. In fact one of the earliest Egyptian words for a seagoing ship is a "Byblos Ship", which originally defined a class of Egyptian seagoing ships used on the Byblos run; however, by the end of the Old Kingdom, the term had come to include large seagoing ships, whatever their destination.In 2011 archaeologists from Italy, the United States, and Egypt excavating a dried-up lagoon known as Mersa Gawasis have unearthed traces of an ancient harbor that once launched early voyages like Hatshepsut's Punt expedition onto the open ocean. Some of the site's most evocative evidence for the ancient Egyptians' seafaring prowess include large ship timbers and hundreds of feet of ropes, made from papyrus, coiled in huge bundles. And in 2013 a team of Franco-Egyptian archaeologists discovered what is believed to be the world's oldest port, dating back about 4500 years, from the time of King Cheops on the Red Sea coast near Wadi el-Jarf (about 110 miles south of Suez).In 1977, an ancient north-south canal dating to the Middle Kingdom of Egypt was discovered extending from Lake Timsah to the Ballah Lakes. It was dated to the Middle Kingdom of Egypt by extrapolating dates of ancient sites constructed along its course. === Mathematics === The earliest attested examples of mathematical calculations date to the predynastic Naqada period, and show a fully developed numeral system. The importance of mathematics to an educated Egyptian is suggested by a New Kingdom fictional letter in which the writer proposes a scholarly competition between himself and another scribe regarding everyday calculation tasks such as accounting of land, labor, and grain. Texts such as the Rhind Mathematical Papyrus and the Moscow Mathematical Papyrus show that the ancient Egyptians could perform the four basic mathematical operations—addition, subtraction, multiplication, and division—use fractions, compute the volumes of boxes and pyramids, and calculate the surface areas of rectangles, triangles, and circles. They understood basic concepts of algebra and geometry, and could solve simple sets of simultaneous equations. Mathematical notation was decimal, and based on hieroglyphic signs for each power of ten up to one million. Each of these could be written as many times as necessary to add up to the desired number; so to write the number eighty or eight hundred, the symbol for ten or one hundred was written eight times respectively. Because their methods of calculation could not handle most fractions with a numerator greater than one, they had to write fractions as the sum of several fractions. For example, they resolved the fraction two-fifths into the sum of one-third + one-fifteenth. Standard tables of values facilitated this. Some common fractions, however, were written with a special glyph—the equivalent of the modern two-thirds is shown on the right.Ancient Egyptian mathematicians knew the Pythagorean theorem as an empirical formula. They were aware, for example, that a triangle had a right angle opposite the hypotenuse when its sides were in a 3–4–5 ratio. They were able to estimate the area of a circle by subtracting one-ninth from its diameter and squaring the result: Area ≈ [(​8⁄9)D]2 = (​256⁄81)r 2 ≈ 3.16r 2,a reasonable approximation of the formula πr 2.The golden ratio seems to be reflected in many Egyptian constructions, including the pyramids, but its use may have been an unintended consequence of the ancient Egyptian practice of combining the use of knotted ropes with an intuitive sense of proportion and harmony. == Population == Greek historian Herodotus claimed that ancient Egyptians looked like the people in Colchis (modern-day Georgia). This claim has been largely discredited as fictional by modern-day scholars. For the fact is as I soon came to realise myself, and then heard from others later, that the Colchians are obviously Egyptian. When the notion occurred to me, I asked both the Colchians and the Egyptians about it, and found that the Colchians had better recall of the Egyptians than the Egyptians did of them. Some Egyptians said that they thought the Colchians originated with Sesostris' army, but I myself guessed their Egyptian origin not only because the Colchians are dark-skinned and curly-haired (which does not count for much by itself, because these features are common in others too) but more importantly because Colchians, Egyptians and Ethiopians are the only peoples in the world who practise circumcision and who have always done so. A team led by Johannes Krause managed the first reliable sequencing of the genomes of 90 mummified individuals in 2017. Whilst not conclusive, because of the non-exhaustive time frame and restricted location that the mummies represent, their study nevertheless showed that these ancient Egyptians "closely resembled ancient and modern Near Eastern populations, especially those in the Levant, and had almost no DNA from sub-Saharan Africa. What's more, the genetics of the mummies remained remarkably consistent even as different powers—including Nubians, Greeks, and Romans—conquered the empire." Later, however, something did alter the genomes of Egyptians. Some 15% to 20% of modern Egyptians' DNA reflects sub-Saharan ancestry, but the ancient mummies had only 6–15% sub-Saharan DNA. == Legacy == The culture and monuments of ancient Egypt have left a lasting legacy on the world. The cult of the goddess Isis, for example, became popular in the Roman Empire, as obelisks and other relics were transported back to Rome. The Romans also imported building materials from Egypt to erect Egyptian-style structures. Early historians such as Herodotus, Strabo, and Diodorus Siculus studied and wrote about the land, which Romans came to view as a place of mystery.During the Middle Ages and the Renaissance, Egyptian pagan culture was in decline after the rise of Christianity and later Islam, but interest in Egyptian antiquity continued in the writings of medieval scholars such as Dhul-Nun al-Misri and al-Maqrizi. In the seventeenth and eighteenth centuries, European travelers and tourists brought back antiquities and wrote stories of their journeys, leading to a wave of Egyptomania across Europe. This renewed interest sent collectors to Egypt, who took, purchased, or were given many important antiquities.Although the European colonial occupation of Egypt destroyed a significant portion of the country's historical legacy, some foreigners left more positive marks. Napoleon, for example, arranged the first studies in Egyptology when he brought some 150 scientists and artists to study and document Egypt's natural history, which was published in the Description de l'Égypte.In the 20th century, the Egyptian Government and archaeologists alike recognized the importance of cultural respect and integrity in excavations. The Supreme Council of Antiquities now approves and oversees all excavations, which are aimed at finding information rather than treasure. The council also supervises museums and monument reconstruction programs designed to preserve the historical legacy of Egypt. == See also == Glossary of ancient Egypt artifacts Index of ancient Egypt-related articles Outline of ancient Egypt List of ancient Egyptians == Notes == == References == == Further reading == Baines, John & Jaromir Málek (2000).

### Instruction: retrieve labels for this: An abjad (pronounced or ) is a type of writing system where each symbol or glyph stands for a consonant, leaving the reader to supply the appropriate vowel. So-called impure abjads do represent vowels, either with optional diacritics, a limited number of distinct vowel glyphs, or both. The name abjad is based on the old Arabic alphabet's first four letters – a, b, j, d – to replace the common terms "consonantary", "consonantal alphabet" or "syllabary" to refer to the family of scripts called West Semitic. == Etymology == The name "abjad" (abjad أبجد) is derived from pronouncing the first letters of the Arabic alphabet in order. The ordering (abjadī) of Arabic letters used to match that of the older Hebrew, Phoenician and Semitic alphabets: ʾ (aleph) - b - g - d. == Terminology == According to the formulations of Daniels, abjads differ from alphabets in that only consonants, not vowels, are represented among the basic graphemes. Abjads differ from abugidas, another category defined by Daniels, in that in abjads, the vowel sound is implied by phonology, and where vowel marks exist for the system, such as nikkud for Hebrew and ḥarakāt for Arabic, their use is optional and not the dominant (or literate) form. Abugidas mark the vowels (other than the "inherent" vowel) with a diacritic, a minor attachment to the letter, or a standalone glyph. Some abugidas use a special symbol to suppress the inherent vowel so that the consonant alone can be properly represented. In a syllabary, a grapheme denotes a complete syllable, that is, either a lone vowel sound or a combination of a vowel sound with one or more consonant sounds. The antagonism of abjad versus alphabet, as it was formulated by Daniels, has been rejected by other scholars because abjad is also used as a term not only for the Arabic numeral system but, which is most important in terms of historical grammatology, also as term for the alphabetic device (i.e. letter order) of ancient Northwest Semitic scripts in opposition to the 'south Arabian' order. This caused fatal effects on terminology in general and especially in (ancient) Semitic philology. Also, it suggests that consonantal alphabets, in opposition to, for instance, the Greek alphabet, were not yet true alphabets and not yet entirely complete, lacking something important to be a fully working script system. It has also been objected that, as a set of letters, an alphabet is not the mirror of what should be there in a language from a phonological point of view; rather, it is the data stock of what provides maximum efficiency with least effort from a semantic point of view. == Origins == The first abjad to gain widespread usage was the Phoenician abjad. Unlike other contemporary scripts, such as cuneiform and Egyptian hieroglyphs, the Phoenician script consisted of only a few dozen symbols. This made the script easy to learn, and seafaring Phoenician merchants took the script wherever they went. The Phoenician abjad was a radical simplification of phonetic writing, since hieroglyphics required the writer to pick a hieroglyph starting with the same sound that the writer wanted to write in order to write phonetically, much as man'yougana (Chinese characters, or kanji, used solely for phonetic use) was used to represent Japanese phonetically before the invention of kana. Phoenician gave rise to a number of new writing systems, including the Greek alphabet and Aramaic, a widely used abjad. The Greek alphabet evolved into the modern western alphabets, such as Latin and Cyrillic, while Aramaic became the ancestor of many modern abjads and abugidas of Asia. == Impure abjads == Impure abjads have characters for some vowels, optional vowel diacritics, or both. The term pure abjad refers to scripts entirely lacking in vowel indicators. However, most modern abjads, such as Arabic, Hebrew, Aramaic and Pahlavi, are "impure" abjads – that is, they also contain symbols for some of the vowel phonemes, although the said non-diacritic vowel letters are also used to write certain consonants, particularly approximants that sound similar to long vowels. A "pure" abjad is exemplified (perhaps) by very early forms of ancient Phoenician, though at some point (at least by the 9th century BC) it and most of the contemporary Semitic abjads had begun to overload a few of the consonant symbols with a secondary function as vowel markers, called matres lectionis. This practice was at first rare and limited in scope but became increasingly common and more developed in later times. === Addition of vowels === In the 9th century BC the Greeks adapted the Phoenician script for use in their own language. The phonetic structure of the Greek language created too many ambiguities when vowels went unrepresented, so the script was modified. They did not need letters for the guttural sounds represented by aleph, he, heth or ayin, so these symbols were assigned vocalic values. The letters waw and yod were also adapted into vowel signs; along with he, these were already used as matres lectionis in Phoenician. The major innovation of Greek was to dedicate these symbols exclusively and unambiguously to vowel sounds that could be combined arbitrarily with consonants (as opposed to syllabaries such as Linear B which usually have vowel symbols but cannot combine them with consonants to form arbitrary syllables). Abugidas developed along a slightly different route. The basic consonantal symbol was considered to have an inherent "a" vowel sound. Hooks or short lines attached to various parts of the basic letter modify the vowel. In this way, the South Arabian alphabet evolved into the Ge'ez alphabet between the 5th century BC and the 5th century AD. Similarly, around the 3rd century BC, the Brāhmī script developed (from the Aramaic abjad, it has been hypothesized). The other major family of abugidas, Canadian Aboriginal syllabics, was initially developed in the 1840s by missionary and linguist James Evans for the Cree and Ojibwe languages. Evans used features of Devanagari script and Pitman shorthand to create his initial abugida. Later in the 19th century, other missionaries adapted Evans' system to other Canadian aboriginal languages. Canadian syllabics differ from other abugidas in that the vowel is indicated by rotation of the consonantal symbol, with each vowel having a consistent orientation. == Abjads and the structure of Semitic languages == The abjad form of writing is well-adapted to the morphological structure of the Semitic languages it was developed to write. This is because words in Semitic languages are formed from a root consisting of (usually) three consonants, the vowels being used to indicate inflectional or derived forms. For instance, according to Classical Arabic and Modern Standard Arabic, from the Arabic root ذ ب ح Dh-B-Ḥ (to slaughter) can be derived the forms ذَبَحَ dhabaḥa (he slaughtered), ذَبَحْتَ dhabaḥta (you (masculine singular) slaughtered), يُذَبِّحُ yudhabbiḥu (he slaughters), and مَذْبَح madhbaḥ (slaughterhouse). In most cases, the absence of full glyphs for vowels makes the common root clearer, allowing readers to guess the meaning of unfamiliar words from familiar roots (especially in conjunction with context clues) and improving word recognition while reading for practiced readers. == Comparative chart of Abjads, extinct and extant == == See also == Abjad numerals Abugida Gematria (Hebrew system of mystical numerology) Numerology Shorthand (constructed writing systems that are structurally abjads) == References == == Sources == ### Answer: <Abjad writing systems>

### Instruction: retrieve labels for this: An abugida (from Ge'ez: አቡጊዳ ’abugida), or alphasyllabary, is a segmental writing system in which consonant–vowel sequences are written as a unit: each unit is based on a consonant letter, and vowel notation is secondary. This contrasts with a full alphabet, in which vowels have status equal to consonants, and with an abjad, in which vowel marking is absent, partial, or optional (although in a less formal contexts, all three types of script may be termed alphabets.) The terms also contrast them with a syllabary, in which the symbols cannot be split into separate consonants and vowels. Abugidas include the extensive Brahmic family of scripts of South and Southeast Asia, Semitic Ethiopic scripts, and Canadian Aboriginal syllabics (which are themselves based in part on Brahmic scripts). As is the case for syllabaries, the units of the writing system may consist of the representations both of syllables and of consonants. For scripts of the Brahmic family, the term akshara is used for the units. Abugida as a term in linguistics was proposed by Peter T. Daniels in his 1990 typology of writing systems. ’Äbugida is an Ethiopian name for the Ge‘ez script, taken from four letters of that script, 'ä bu gi da, in much the same way that abecedary is derived from Latin a be ce de, abjad is derived from the Arabic a b j d, and alphabet is derived from the names of the two first letters in the Greek alphabet, alpha and beta. As Daniels used the word, an abugida is in contrast with a syllabary, where letters with shared consonants or vowels show no particular resemblance to one another, and also with an alphabet proper, where independent letters are used to denote both consonants and vowels. The term alphasyllabary was suggested for the Indic scripts in 1997 by William Bright, following South Asian linguistic usage, to convey the idea that "they share features of both alphabet and syllabary."Abugidas were long considered to be syllabaries, or intermediate between syllabaries and alphabets, and the term syllabics is retained in the name of Canadian Aboriginal Syllabics. Other terms that have been used include neosyllabary (Février 1959), pseudo-alphabet (Householder 1959), semisyllabary (Diringer 1968; a word that has other uses) and syllabic alphabet (Coulmas 1996; this term is also a synonym for syllabary). == General description == The formal definitions given by Daniels and Bright for abugida and alphasyllabary differ; some writing systems are abugidas but not alphasyllabaries, and some are alphasyllabaries but not abugidas. An abugida is defined as "a type of writing system whose basic characters denotes consonants followed by a particular vowel, and in which diacritics denote other vowels". (This 'particular vowel' is referred to as the inherent or implicit vowel, as opposed to the explicit vowels marked by the 'diacritics'.) An alphasyllabary is defined as "a type of writing system in which the vowels are denoted by subsidiary symbols not all of which occur in a linear order (with relation to the consonant symbols) that is congruent with their temporal order in speech". Bright did not require that an alphabet explicitly represent all vowels. Phagspa is an example of an abugida that is not an alphasyllabary, and modern Lao is an example of an alphasyllabary that is not an abugida, for its vowels are always explicit. This description is expressed in terms of an abugida. Formally, an alphasyllabary that is not an abugida can be converted to an abugida by adding a purely formal vowel sound that is never used and declaring that to be the inherent vowel of the letters representing consonants. This may formally make the system ambiguous, but in 'practice' this is not a problem, for then the interpretation with the never used inherent vowel sound will always be a wrong interpretation. Note that the actual pronunciation may be complicated by interactions between the sounds apparently written just as the sounds of the letters in the English words wan, gem and war are affected by neighbouring letters. The fundamental principles of an abugida apply to words made up of consonant-vowel (CV) syllables. The syllables are written as a linear sequences of the units of the script. Each syllable is either a letter that represents the sound of a consonant and the inherent vowel, or a letter with a modification to indicate the vowel, either by means of diacritics, or by changes in the form of the letter itself. If all modifications are by diacritics and all diacritics follow the direction of the writing of the letters, then the abugida is not an alphasyllabary. However, most languages have words that are more complicated than a sequence of CV syllables, even ignoring tone. The first complication is syllables that consist of just a vowel (V). Now, in some languages, this issue does not arise, for every syllable starts with a consonant. This is common in Semitic languages and in languages of mainland SE Asia, and for such languages this issue need not arise. For some languages, a zero consonant letter is used as though every syllable began with a consonant. For other languages, each vowel has a separate letter that is used for each syllable consisting of just the vowel. These letters are known as independent vowels, and are found in most Indic scripts. These letters may be quite different to the corresponding diacritics, which by contrast are known as dependent vowels. As a result of the spread of writing systems, independent vowels may be used to represent syllables beginning with a glottal stop, even for non-initial syllables. The next two complications are sequences of consonants before a vowel (CCV) and syllables ending in a consonant (CVC). The simplest solution, which is not always available, is to break with the principle of writing words as a sequence of syllables and use a unit representing just a consonant (C). This unit may be represented with: a modification that explicitly indicates the lack of a vowel (virama), a lack of vowel marking (often with ambiguity between no vowel and a default inherent vowel), vowel marking for a short or neutral vowel such as schwa (with ambiguity between no vowel and that short or neutral vowel), or a visually unrelated letter.In a true abugida, the lack of distinctive marking may result from the diachronic loss of the inherent vowel, e.g. by syncope and apocope in Hindi. When not handled by decomposition into C + CV, CCV syllables are handled by combining the two consonants. In the Indic scripts, the earliest method was simply to arrange them vertically, but the two consonants may merge as a conjunct consonant letters, where two or more letters are graphically joined in a ligature, or otherwise change their shapes. Rarely, one of the consonants may be replaced by a gemination mark, e.g. the Gurmukhi addak. When they are arranged vertically, as in Burmese or Khmer, they are said to be 'stacked'. Often there has been a change to writing the two consonants side by side. In the latter case, the fact of combination may be indicated by a diacritic on one of the consonants or a change in the form of one of the consonants, e.g. the half forms of Devanagari. Generally, the reading order is top to bottom or the general reading order of the script, but sometimes the order is reversed. The division of a word into syllables for the purposes of writing does not always accord with the natural phonetics of the language. For example, Brahmic scripts commonly handle a phonetic sequence CVC-CV as CV-CCV or CV-C-CV. However, sometimes phonetic CVC syllables are handled as single units, and the final consonant may be represented: in much the same way as the second consonant in CCV, e.g. in the Tibetan, Khmer and Tai Tham scripts. The positioning of the components may be slightly different, as in Khmer and Tai Tham. by a special dependent consonant sign, which may be a smaller or differently placed version of the full consonant letter, or may be a distinct sign altogether. not at all. For example, repeated consonants need not be represented, homorganic nasals may be ignored, and in Philippine scripts, the syllable-final consonant was traditionally never represented.More complicated unit structures (e.g. CC or CCVC) are handled by combining the various techniques above. == Family-specific features == There are three principal families of abugidas, depending on whether vowels are indicated by modifying consonants by diacritics, distortion, or orientation. The oldest and largest is the Brahmic family of India and Southeast Asia, in which vowels are marked with diacritics and syllable-final consonants, when they occur, are indicated with ligatures, diacritics, or with a special vowel-canceling mark. In the Ethiopic family, vowels are marked by modifying the shapes of the consonants, and one of the vowel-forms serves additionally to indicate final consonants. In the Cree family, vowels are marked by rotating or flipping the consonants, and final consonants are indicated with either special diacritics or superscript forms of the main initial consonants.Tāna of the Maldives has dependent vowels and a zero vowel sign, but no inherent vowel. === Indic (Brahmic) === Indic scripts originated in India and spread to Southeast Asia. All surviving Indic scripts are descendants of the Brahmi alphabet. Today they are used in most languages of South Asia (although replaced by Perso-Arabic in Urdu, Kashmiri and some other languages of Pakistan and India), mainland Southeast Asia (Myanmar, Thailand, Laos, and Cambodia), and Indonesian archipelago (Javanese, Balinese, Sundanese, etc.). The primary division is into North Indic scripts used in Northern India, Nepal, Tibet and Bhutan, and Southern Indic scripts used in South India, Sri Lanka and Southeast Asia. South Indic letter forms are very rounded; North Indic less so, though Odia, Golmol and Litumol of Nepal script are rounded. Most North Indic scripts' full letters incorporate a horizontal line at the top, with Gujarati and Odia as exceptions; South Indic scripts do not. Indic scripts indicate vowels through dependent vowel signs (diacritics) around the consonants, often including a sign that explicitly indicates the lack of a vowel. If a consonant has no vowel sign, this indicates a default vowel. Vowel diacritics may appear above, below, to the left, to the right, or around the consonant. The most widely used Indic script is Devanagari, shared by Hindi, Bhojpuri, Marathi, Konkani, Nepali, and often Sanskrit. A basic letter such as क in Hindi represents a syllable with the default vowel, in this case ka ([kə]). In some languages, including Hindi, it becomes a final closing consonant at the end of a word, in this case k. The inherent vowel may be changed by adding vowel mark (diacritics), producing syllables such as कि ki, कु ku, के ke, को ko. In many of the Brahmic scripts, a syllable beginning with a cluster is treated as a single character for purposes of vowel marking, so a vowel marker like ि -i, falling before the character it modifies, may appear several positions before the place where it is pronounced. For example, the game cricket in Hindi is क्रिकेट krikeţ; the diacritic for /i/ appears before the consonant cluster /kr/, not before the /r/. A more unusual example is seen in the Batak alphabet: Here the syllable bim is written ba-ma-i-(virama). That is, the vowel diacritic and virama are both written after the consonants for the whole syllable. In many abugidas, there is also a diacritic to suppress the inherent vowel, yielding the bare consonant. In Devanagari, क् is k, and ल् is l. This is called the virāma or halantam in Sanskrit. It may be used to form consonant clusters, or to indicate that a consonant occurs at the end of a word. Thus in Sanskrit, a default vowel consonant such as क does not take on a final consonant sound. Instead, it keeps its vowel. For writing two consonants without a vowel in between, instead of using diacritics on the first consonant to remove its vowel, another popular method of special conjunct forms is used in which two or more consonant characters are merged to express a cluster, such as Devanagari: क्ल kla. (Note that some fonts display this as क् followed by ल, rather than forming a conjunct. This expedient is used by ISCII and South Asian scripts of Unicode.) Thus a closed syllable such as kal requires two aksharas to write. The Róng script used for the Lepcha language goes further than other Indic abugidas, in that a single akshara can represent a closed syllable: Not only the vowel, but any final consonant is indicated by a diacritic. For example, the syllable [sok] would be written as something like s̥̽, here with an underring representing /o/ and an overcross representing the diacritic for final /k/. Most other Indic abugidas can only indicate a very limited set of final consonants with diacritics, such as /ŋ/ or /r/, if they can indicate any at all. === Ethiopic === In Ethiopic (where the term abugida originates) the diacritics have been fused to the consonants to the point that they must be considered modifications of the form of the letters. Children learn each modification separately, as in a syllabary; nonetheless, the graphic similarities between syllables with the same consonant is readily apparent, unlike the case in a true syllabary. Though now an abugida, the Ge'ez script, until the advent of Christianity (ca. AD 350), had originally been what would now be termed an abjad. In the Ge'ez abugida (or fidel), the base form of the letter (also known as fidel) may be altered. For example, ሀ hä [hə] (base form), ሁ hu (with a right-side diacritic that doesn't alter the letter), ሂ hi (with a subdiacritic that compresses the consonant, so it is the same height), ህ hə [hɨ] or [h] (where the letter is modified with a kink in the left arm). === Canadian Aboriginal syllabics === In the family known as Canadian Aboriginal syllabics, which was inspired by the Devanagari script of India, vowels are indicated by changing the orientation of the syllabogram. Each vowel has a consistent orientation; for example, Inuktitut ᐱ pi, ᐳ pu, ᐸ pa; ᑎ ti, ᑐ tu, ᑕ ta. Although there is a vowel inherent in each, all rotations have equal status and none can be identified as basic. Bare consonants are indicated either by separate diacritics, or by superscript versions of the aksharas; there is no vowel-killer mark. == Borderline cases == === Vowelled abjads === Consonantal scripts ("abjads") are normally written without indication of many vowels. However, in some contexts like teaching materials or scriptures, Arabic and Hebrew are written with full indication of vowels via diacritic marks (harakat, niqqud) making them effectively alphasyllabaries. The Brahmic and Ethiopic families are thought to have originated from the Semitic abjads by the addition of vowel marks. The Arabic scripts used for Kurdish in Iraq and for Uyghur in Xinjiang, China, as well as the Hebrew script of Yiddish, are fully vowelled, but because the vowels are written with full letters rather than diacritics (with the exception of distinguishing between /a/ and /o/ in the latter) and there are no inherent vowels, these are considered alphabets, not abugidas. === Phagspa === The imperial Mongol script called Phagspa was derived from the Tibetan abugida, but all vowels are written in-line rather than as diacritics. However, it retains the features of having an inherent vowel /a/ and having distinct initial vowel letters. === Pahawh === Pahawh Hmong is a non-segmental script that indicates syllable onsets and rimes, such as consonant clusters and vowels with final consonants. Thus it is not segmental and cannot be considered an abugida. However, it superficially resembles an abugida with the roles of consonant and vowel reversed. Most syllables are written with two letters in the order rime–onset (typically vowel-consonant), even though they are pronounced as onset-rime (consonant-vowel), rather like the position of the /i/ vowel in Devanagari, which is written before the consonant. Pahawh is also unusual in that, while an inherent rime /āu/ (with mid tone) is unwritten, it also has an inherent onset /k/. For the syllable /kau/, which requires one or the other of the inherent sounds to be overt, it is /au/ that is written. Thus it is the rime (vowel) that is basic to the system. === Meroitic === It is difficult to draw a dividing line between abugidas and other segmental scripts. For example, the Meroitic script of ancient Sudan did not indicate an inherent a (one symbol stood for both m and ma, for example), and is thus similar to Brahmic family of abugidas. However, the other vowels were indicated with full letters, not diacritics or modification, so the system was essentially an alphabet that did not bother to write the most common vowel. === Shorthand === Several systems of shorthand use diacritics for vowels, but they do not have an inherent vowel, and are thus more similar to Thaana and Kurdish script than to the Brahmic scripts. The Gabelsberger shorthand system and its derivatives modify the following consonant to represent vowels. The Pollard script, which was based on shorthand, also uses diacritics for vowels; the placements of the vowel relative to the consonant indicates tone. Pitman shorthand uses straight strokes and quarter-circle marks in different orientations as the principal "alphabet" of consonants; vowels are shown as light and heavy dots, dashes and other marks in one of 3 possible positions to indicate the various vowel-sounds. However, to increase writing speed, Pitman has rules for "vowel indication" using the positioning or choice of consonant signs so that writing vowel-marks can be dispensed with. == Development == As the term alphasyllabary suggests, abugidas have been considered an intermediate step between alphabets and syllabaries. Historically, abugidas appear to have evolved from abjads (vowelless alphabets). They contrast with syllabaries, where there is a distinct symbol for each syllable or consonant-vowel combination, and where these have no systematic similarity to each other, and typically develop directly from logographic scripts. Compare the Devanagari examples above to sets of syllables in the Japanese hiragana syllabary: か ka, き ki, く ku, け ke, こ ko have nothing in common to indicate k; while ら ra, り ri, る ru, れ re, ろ ro have neither anything in common for r, nor anything to indicate that they have the same vowels as the k set. Most Indian and Indochinese abugidas appear to have first been developed from abjads with the Kharoṣṭhī and Brāhmī scripts; the abjad in question is usually considered to be the Aramaic one, but while the link between Aramaic and Kharosthi is more or less undisputed, this is not the case with Brahmi. The Kharosthi family does not survive today, but Brahmi's descendants include most of the modern scripts of South and Southeast Asia. Ge'ez derived from a different abjad, the Sabean script of Yemen; the advent of vowels coincided with the introduction of Christianity about AD 350.The Ethiopic script is the elaboration of an abjad. The Cree family was invented with full knowledge of the Devanagari system. The Meroitic script was developed from Egyptian hieroglyphs, within which various schemes of 'group writing' had been used for showing vowels. == Other types of writing systems == Featural alphabet Abjad Alphabet Logogram Syllabary == List of abugidas == Brahmic family, descended from Brāhmī (c. 6th century BC) Ahom Brahmi – Sanskrit, Prakrit Balinese Batak – Toba and other Batak languages Baybayin – Ilocano, Kapampangan, Pangasinan, Tagalog, Bikol languages, Visayan languages, and possibly other Philippine languages Bengali-Assamese script – Bengali, Assamese, Meithei, Bishnupriya Manipuri, Kokborok, Khasi language, Bodo language Bhaiksuki Buhid Burmese – Burmese, Karen languages, Mon, and Shan Cham Chakma Dehong – Dehong Dai Devanagari – Hindi, Sanskrit, Marathi, Nepali, and many other languages of northern India Dhives Akuru Grantha – Sanskrit Gujarati – Gujarāti, Kachchi Gurmukhi script – Punjabi Hanunó’o Javanese Kaithi Kannada – Kannada, Tulu, Konkani, Kodava Kawi Khojki Khotanese Khudawadi Khmer Kolezhuthu – Tamil, Malayalam Lao Lepcha Leke Limbu Lontara’ – Buginese, Makassar, and Mandar Mahajani Malayalam – Malayalam Malayanma – Malayalam Marchen – Zhang-Zhung Meetei Mayek Meroitic Modi – Marathi Multani – Saraiki Nandinagari – Sanskrit Newar – Nepal Bhasa, Sanskrit New Tai Lue Oriya Pallava script – Tamil, Prakrit, Sanskrit Phags-pa – Mongolian, Chinese, and other languages of the Yuan dynasty Mongol Empire Ranjana – Nepal Bhasa, Sanskrit Rejang Sharada – Sanskrit Siddham – Sanskrit Sinhala Sourashtra Soyombo Sundanese Syloti Nagri – Sylheti Tagbanwa – Palawan languages Tai Le Tai Dam Tai Tham – Khün, and Northern Thai Takri Tamil Telugu Thai Tibetan Tigalari – Sanskrit Tirhuta – Maithili Tocharian Vatteluttu – Tamil, Malayalam Zanabazar Square Zhang zhung scripts Kharoṣṭhī (extinct), from the 3rd century BC Ge'ez (Ethiopic), from the 4th century AD Canadian Aboriginal syllabics Cree – Ojibwe syllabics Inuktitut syllabics Blackfoot syllabics Carrier syllabics Thaana Pollard script Pitman shorthand Tengwar (fictional) Ihathvé Sabethired (fictional) === Abugida-like scripts === Meroitic (extinct) (an alphabet with an inherent vowel) == References == == External links == Syllabic alphabets – Omniglot's list of abugidas, including examples of various writing systems Alphabets – list of abugidas and other scripts (in Spanish) Comparing Devanagari with Burmese, Khmer, Thai, and Tai Tham scripts ### Answer: <Abugida writing systems>

### Instruction: retrieve labels for this: ABBA (Swedish pronunciation: [²abːa]) are a Swedish pop group, formed in Stockholm in 1972 by Agnetha Fältskog, Björn Ulvaeus, Benny Andersson, and Anni-Frid Lyngstad. The group's name derives from the first letter in each of the first names of its members. They became one of the most commercially successful acts in the history of popular music, topping the charts worldwide from 1974 to 1982. ABBA won the Eurovision Song Contest 1974 at The Dome in Brighton, UK, giving Sweden its first triumph in the contest. They are the most successful group to have taken part in the competition. ABBA's record sales are estimated from 140 to over 500 million copies worldwide, making them one of the best-selling music artists of all time. They are also the best-selling band from continental Europe and from outside the English-speaking world. ABBA is the first group from a non-English-speaking country to achieve consistent success in the charts of English-speaking countries, including the United Kingdom, Ireland, Canada, Australia, New Zealand, South Africa, and the United States. They have a joint record eight consecutive number-one albums in the UK. The group also enjoyed significant success in Latin America, and recorded a collection of their hit songs in Spanish. During the band's active years, the band was composed of two couples: Fältskog and Ulvaeus, and Lyngstad and Andersson. With the increase of their popularity, their personal lives suffered which eventually resulted in the collapse of both marriages. The relationship changes were reflected in the group's music, with later compositions featuring more introspective and dark lyrics.After ABBA disbanded in December 1982, Andersson and Ulvaeus achieved success writing music for the stage, while Lyngstad and Fältskog pursued solo careers with mixed success. ABBA's music declined in popularity until the purchase of ABBA's catalogue and record company Polar by Polygram in 1989 enabled the groundwork to be laid for an international re-issue of all their original material and a new Greatest Hits (ABBA Gold) collection in September 1992, which became a worldwide bestseller. Several films, notably Muriel's Wedding (1994) and The Adventures of Priscilla, Queen of the Desert (1994), further revived interest in the group and spawned several tribute bands. In 1999, ABBA's music was adapted into the successful musical Mamma Mia! that toured worldwide. A film of the same name, released in 2008, became the highest-grossing film in the United Kingdom that year. A sequel, Mamma Mia! Here We Go Again, was released in 2018. ABBA were honoured at the 50th anniversary celebration of the Eurovision Song Contest in 2005, when their hit "Waterloo" was chosen as the best song in the competition's history. The group was inducted into the Rock and Roll Hall of Fame in 2010. In 2015, their song "Dancing Queen" was inducted into the Recording Academy's Grammy Hall of Fame. On April 27, 2018, it was announced that the band had recorded two new songs after 35 years of being inactive, the first of which – "I Still Have Faith in You" – will be released in December 2018. == History == === 1958–1970: Before ABBA === ==== Member origins and collaboration ==== Benny Andersson (born 16 December 1946 in Stockholm, Sweden) became (at age 18) a member of a popular Swedish pop-rock group, the Hep Stars, that performed covers, amongst other things, of international hits. The Hep Stars were known as "the Swedish Beatles". They also set up Hep House, their equivalent of Apple Corps. Andersson played the keyboard and eventually started writing original songs for his band, many of which became major hits, including "No Response" that hit number-three in 1965, "Sunny Girl", "Wedding", and "Consolation", all of which hit number-one in 1966. Andersson also had a fruitful songwriting collaboration with Lasse Berghagen, with whom he wrote his first Svensktoppen entry, "Sagan om lilla Sofie" ("The Story of Little Sophie"), in 1968. Björn Ulvaeus (born 25 April 1945 in Gothenburg, Sweden) also began his musical career at 18 (as a singer and guitarist), when he fronted the Hootenanny Singers, a popular Swedish folk–skiffle group. Ulvaeus started writing English-language songs for his group, and even had a brief solo career alongside. The Hootenanny Singers and the Hep Stars sometimes crossed paths while touring. In June 1966, Ulvaeus and Andersson decided to write a song together. Their first attempt was "Isn't It Easy to Say", a song later recorded by the Hep Stars. Stig Anderson was the manager of the Hootenanny Singers and founder of the Polar Music label. He saw potential in the collaboration, and encouraged them to write more. The two also began playing occasionally with the other's bands on stage and on record, although it was not until 1969 that the pair wrote and produced some of their first real hits together: "Ljuva sextital" ("Sweet Sixties"), recorded by Brita Borg, and the Hep Stars' 1969 hit "Speleman" ("Fiddler"). Andersson wrote and submitted the song "Hej, Clown" for Melodifestivalen 1969, the national festival to select the Swedish entry to the Eurovision Song Contest. The song tied for first place, but re-voting relegated Andersson's song to second place. On that occasion Andersson briefly met his future spouse, singer Anni-Frid Lyngstad, who also participated in the contest. A month later, the two had become a couple. As their respective bands began to break up during 1969, Andersson and Ulvaeus teamed up and recorded their first album together in 1970, called Lycka ("Happiness"), which included original songs sung by both men. Their spouses were often present in the recording studio, and sometimes added backing vocals; Fältskog even co-wrote a song with the two. Ulvaeus still occasionally recorded and performed with the Hootenanny Singers until the middle of 1974, and Andersson took part in producing their records. Agnetha Fältskog (born 5 April 1950 in Jönköping, Sweden) sang with a local dance band headed by Bernt Enghardt who sent a demo recording of the band to Karl Gerhard Lundkvist. The demo tape featured a song written and sung by Agnetha: "Jag var så kär" ("I Was So in Love"). Lundkvist was so impressed with her voice that he was convinced she would be a star. After going through considerable effort to locate the singer, he arranged for Agnetha to come to Stockholm and to record two of her own songs. This led to Agnetha at the age of 18 having a number-one record in Sweden with a self-composed song, which later went on to sell over 80,000 copies. She was soon noticed by the critics and songwriters as a talented singer/songwriter of schlager style songs. Fältskog's main inspiration in her early years were singers such as Connie Francis. Along with her own compositions, she recorded covers of foreign hits and performed them on tours in Swedish folkparks. Most of her biggest hits were self-composed, which was quite unusual for a female singer in the 1960s. Agnetha released four solo LPs between 1968 and 1971. She had many successful singles in the Swedish charts. During filming of a Swedish TV special in May 1969, Fältskog met Ulvaeus, and they married on 6 July 1971. Fältskog and Ulvaeus eventually were involved in each other's recording sessions, and soon even Andersson and Lyngstad added backing vocals to her third studio album, Som jag är ("As I Am") (1970). In 1972, Fältskog starred as Mary Magdalene in the original Swedish production of Jesus Christ Superstar and attracted favourable reviews. Between 1967 and 1975, Fältskog released five studio albums.Anni-Frid "Frida" Lyngstad (born 15 November 1945 in Bjørkåsen in Ballangen, Norway) sang from the age of 13 with various dance bands, and worked mainly in a jazz-oriented cabaret style. She also formed her own band, the Anni-Frid Four. In the middle of 1967, she won a national talent competition with "En ledig dag" ("A Day Off") a Swedish version of the bossa nova song "A Day in Portofino", which is included in the EMI compilation Frida 1967–1972. The first prize was a recording contract with EMI Sweden and to perform live on the most popular TV shows in the country. This TV performance, amongst many others, is included in the 3½-hour documentary Frida – The DVD. Lyngstad released several schlager style singles on EMI without much success. When Benny Andersson started to produce her recordings in 1971, she had her first number-one single, "Min egen stad" ("My Own Town"), written by Benny and featuring all the future ABBA members on backing vocals. Lyngstad toured and performed regularly in the folkpark circuit and made appearances on radio and TV. She met Ulvaeus briefly in 1963 during a talent contest, and Fältskog during a TV show in early 1968. Lyngstad linked up with her future bandmates in 1969. On 1 March 1969, she participated in the Melodifestival, where she met Andersson for the first time. A few weeks later they met again during a concert tour in southern Sweden and they soon became a couple. Andersson produced her single "Peter Pan" in September 1969—her first collaboration with Benny & Björn, as they had written the song. Andersson would then produce Lyngstad's debut studio album, Frida, which was released in March 1971. Lyngstad also played in several revues and cabaret shows in Stockholm between 1969 and 1973. After ABBA formed, she recorded another successful album in 1975, Frida ensam, which included a Swedish rendition of "Fernando", a hit on the Swedish radio charts before the English version was released. ==== First live performance and the start of "Festfolket" ==== An attempt at combining their talents occurred in April 1970 when the two couples went on holiday together to the island of Cyprus. What started as singing for fun on the beach ended up as an improvised live performance in front of the United Nations soldiers stationed on the island. Andersson and Ulvaeus were at this time recording their first album together, Lycka, which was to be released in September 1970. Fältskog and Lyngstad added backing vocals on several tracks during June, and the idea of their working together saw them launch a stage act, "Festfolket" (which translates from Swedish to mean both "Party People" and "Engaged Couples"), on 1 November 1970 in Gothenburg. The cabaret show attracted generally negative reviews, except for the performance of the Andersson and Ulvaeus hit "Hej, gamle man" ("Hello, Old Man")–the first Björn and Benny recording to feature all four. They also performed solo numbers from respective albums, but the lukewarm reception convinced the foursome to shelve plans for working together for the time being, and each soon concentrated on individual projects again. ==== First record together "Hej, gamle man" ==== "Hej, gamle man", a song about an old Salvation Army soldier, became the quartet's first hit. The record was credited to Björn & Benny and reached number five on the sales charts and number one on Svensktoppen, staying there for 15 weeks. It was during 1971 that the four artists began working together more, adding vocals to the others' recordings. Fältskog, Andersson and Ulvaeus toured together in May, while Lyngstad toured on her own. Frequent recording sessions brought the foursome closer together during the summer. === 1970–1973: Forming the group === After the 1970 release of Lycka, two more singles credited to "Björn & Benny" were released in Sweden, "Det kan ingen doktor hjälpa" ("No Doctor Can Help with That") and "Tänk om jorden vore ung" ("Imagine If Earth Was Young"), with more prominent vocals by Fältskog and Lyngstad–and moderate chart success. Fältskog and Ulvaeus, now married, started performing together with Andersson on a regular basis at the Swedish folkparks in the middle of 1971. Stig Anderson, founder and owner of Polar Music, was determined to break into the mainstream international market with music by Andersson and Ulvaeus. "One day the pair of you will write a song that becomes a worldwide hit", he predicted. Stig Anderson encouraged Ulvaeus and Andersson to write a song for Melodifestivalen, and after two rejected entries in 1971, Andersson and Ulvaeus submitted their new song "Säg det med en sång" ("Say It with a Song") for the 1972 contest, choosing newcomer Lena Anderson to perform. The song came in third place, encouraging Stig Anderson, and became a hit in Sweden.The first signs of foreign success came as a surprise, as the Andersson and Ulvaeus single "She's My Kind of Girl" was released through Epic Records in Japan in March 1972, giving the duo a Top 10 hit. Two more singles were released in Japan, "En Carousel" ("En Karusell" in Scandinavia, an earlier version of "Merry-Go-Round") and "Love Has Its Ways" (a song they wrote with Kōichi Morita). ==== First hit as Björn & Benny, Agnetha & Anni-Frid/Frida ==== Ulvaeus and Andersson persevered with their songwriting and experimented with new sounds and vocal arrangements. "People Need Love" was released in June 1972, featuring guest vocals by the women, who were now given much greater prominence. Stig Anderson released it as a single, credited to Björn & Benny, Agnetha & Anni-Frid. The song peaked at number 17 in the Swedish combined single and album charts, enough to convince them they were on to something. The single also became the first record to chart for the quartet in the United States, where it peaked at number 114 on the Cashbox singles chart and number 117 on the Record World singles chart. Labeled as Björn & Benny (with Svenska Flicka), it was released there through Playboy Records. However, according to Stig Anderson, "People Need Love" could have been a much bigger American hit, but a small label like Playboy Records did not have the distribution resources to meet the demand for the single from retailers and radio programmers.The foursome decided to record their first album together in late 1972, and sessions began on 26 September 1972. The women shared lead vocals on "Nina, Pretty Ballerina" (a top ten hit in Austria) that day, and their voices in harmony for the first time gave the foursome an idea of the quality of their combined talents. ==== "Ring Ring" ==== In 1973, the band and their manager Stig Anderson decided to have another try at Melodifestivalen, this time with the song "Ring Ring". The studio sessions were handled by Michael B. Tretow, who experimented with a "wall of sound" production technique that became the wholly new sound. Stig Anderson arranged an English translation of the lyrics by Neil Sedaka and Phil Cody and they thought this would be a surefire winner. However, on 10 February 1973, the song came third in Melodifestivalen; thus it never reached the Eurovision Song Contest itself. Nevertheless, the group released their debut studio album, also called Ring Ring. The album did well and the "Ring Ring" single was a hit in many parts of Europe and also in South Africa. However, Stig Anderson felt that the true breakthrough could only come with a UK or US hit.When Agnetha Fältskog gave birth to her daughter Linda in 1973, she was replaced for a short period by Inger Brundin on a trip to West Germany. ==== Official naming ==== In 1973, Stig Anderson, tired of unwieldy names, started to refer to the group privately and publicly as ABBA. At first, this was a play on words, as Abba is also the name of a well-known fish-canning company in Sweden, and itself an acronym. However, since the fish-canners were unknown outside Sweden, Anderson came to believe the name would work in international markets. A competition to find a suitable name for the group was held in a Gothenburg newspaper and it was officially announced in the summer that the group were to be known as "ABBA." The group negotiated with the canners for the rights to the name. "ABBA" is an acronym formed from the first letters of each group member's first name: Agnetha, Björn, Benny and Anni-Frid. The earliest known example of "ABBA" written on paper is on a recording session sheet from the Metronome Studio in Stockholm dated 16 October 1973. This was first written as "Björn, Benny, Agnetha & Frida", but was subsequently crossed out with "ABBA" written in large letters on top. ==== Official logo ==== Their official logo, distinct with the backward ‘B', was designed by Rune Söderqvist, who designed most of ABBA’s record sleeves. The logo first appeared on the French compilation album, Golden Double Album, released in May 1976 by Disques Vogue, and would henceforth be used for all official releases.The idea for the official logo was made by the German photographer Wolfgang "Bubi" Heilemann (de) on a velvet jumpsuit photo shoot for the teenage magazine Bravo. On the photo, the ABBA members held a giant initial letter of his/her name. After the pictures were made, Heilemann found out that Benny Andersson reversed his letter "B"; this prompted discussions about the mirrored "B", and the members of ABBA agreed on the mirrored letter. From 1976 onwards, the first "B" in the logo version of the name was "mirror-image" reversed on the band's promotional material, thus becoming the group's registered trademark. Following their acquisition of the group's catalogue, PolyGram began using variations of the ABBA logo, using a different font and adding a crown emblem to it in 1992 for the first release of the ABBA Gold: Greatest Hits compilation. When Universal Music purchased PolyGram (and, thus, ABBA's label Polar Music International), control of the group's catalogue was returned to Stockholm. Since then, the original logo has been reinstated on all official products. === 1973–1976: Breakthrough === ==== Eurovision Song Contest 1974 ==== As the group entered the Melodifestivalen with "Ring Ring" but failed to qualify as the 1973 Swedish entry, Stig Anderson immediately started planning for the 1974 contest. Ulvaeus, Andersson and Stig Anderson believed in the possibilities of using the Eurovision Song Contest as a way to make the music business aware of them as songwriters, as well as the band itself. In late 1973, they were invited by Swedish television to contribute a song for the Melodifestivalen 1974 and from a number of new songs, the upbeat song "Waterloo" was chosen; the group was now inspired by the growing glam rock scene in England. ABBA won their national heats on Swedish television on 9 February 1974, and with this third attempt were far more experienced and better prepared for the Eurovision Song Contest. Winning the 1974 Contest on 6 April 1974 (and singing Waterloo in English instead of their native tongue) gave ABBA the chance to tour Europe and perform on major television shows; thus the band saw the "Waterloo" single chart in many European countries. "Waterloo" was ABBA's first number-one single in big markets such as the UK and West Germany. In the United States, the song peaked at number-six on the Billboard Hot 100 chart, paving the way for their first album and their first trip as a group there. Albeit a short promotional visit, it included their first performance on American television, The Mike Douglas Show. The album Waterloo only peaked at number 145 on the Billboard 200 chart, but received unanimous high praise from the US critics: Los Angeles Times called it "a compelling and fascinating debut album that captures the spirit of mainstream pop quite effectively … an immensely enjoyable and pleasant project", while Creem characterised it as "a perfect blend of exceptional, lovable compositions".ABBA's follow-up single, "Honey, Honey", peaked at number 27 on the US Billboard Hot 100, and was a number-two hit in West Germany. However, in the United Kingdom, ABBA's British record label, Epic, decided to re-release a remixed version of "Ring Ring" instead of "Honey, Honey", and a cover version of the latter by Sweet Dreams peaked at number 10. Both records debuted on the UK chart within one week of each other. "Ring Ring" failed to reach the Top 30 in the United Kingdom, increasing growing speculation that the group was simply a Eurovision one-hit wonder. ==== Post-Eurovision ==== In November 1974, ABBA embarked on their first European tour, playing dates in Denmark, West Germany and Austria. It was not as successful as the band had hoped, since most of the venues did not sell out. Due to a lack of demand, they were even forced to cancel a few shows, including a sole concert scheduled in Switzerland. The second leg of the tour, which took them through Scandinavia in January 1975, was very different. They played to full houses everywhere and finally got the reception they had aimed for. Live performances continued in the middle of 1975 when ABBA embarked on a fourteen open-air date tour of Sweden and Finland. Their Stockholm show at the Gröna Lund amusement park had an estimated audience of 19,200. Björn Ulvaeus later said that "If you look at the singles we released straight after Waterloo, we were trying to be more like the Sweet, a semi-glam rock group, which was stupid because we were always a pop group."In late 1974, "So Long" was released as a single in the United Kingdom but it received no airplay from Radio 1 and failed to chart. In the middle of 1975, ABBA released "I Do, I Do, I Do, I Do, I Do", which again received little airplay on Radio 1 but managed to climb the charts, to number 38. Later that year, the release of their self-titled third studio album ABBA and single "SOS" brought back their chart presence in the UK, where the single hit number six and the album peaked at number 13. "SOS" also became ABBA's second number-one single in Germany and their third in Australia. Success was further solidified with "Mamma Mia" reaching number-one in the United Kingdom, Germany and Australia. In the United States, "SOS" peaked at number 10 on the Record World Top 100 singles chart and number 15 on the Billboard Hot 100 chart, picking up the BMI Award along the way as one of the most played songs on American radio in 1975. The success of the group in the United States had until that time been limited to single releases. By early 1976, the group already had four Top 30 singles on the US charts, but the album market proved to be tough to crack. The eponymous ABBA album generated three American hits, but it only peaked at number 165 on the Cashbox album chart and number 174 on the Billboard 200 chart. Opinions were voiced, by Creem in particular, that in the US ABBA had endured "a very sloppy promotional campaign". Nevertheless, the group enjoyed warm reviews from the American press. Cashbox went as far as saying that "there is a recurrent thread of taste and artistry inherent in Abba's marketing, creativity and presentation that makes it almost embarrassing to critique their efforts", while Creem wrote: "SOS is surrounded on this LP by so many good tunes that the mind boggles". In Australia, the airing of the music videos for "I Do, I Do, I Do, I Do, I Do" and "Mamma Mia" on the nationally broadcast TV pop show Countdown (which premiered in November 1974) saw the band rapidly gain enormous popularity, and Countdown become a key promoter of the group via their distinctive music videos. This started an immense interest for ABBA in Australia, resulting in both the single and album holding down the No. 1 positions on the charts for months. === 1976–1981: Superstardom === In March 1976, the band released the compilation album Greatest Hits. It became their first UK number-one album, and also took ABBA into the Top 50 on the US album charts for the first time, eventually selling more than a million copies there. At the same time, Germany released a compilation named The Very Best of ABBA, also becoming a number-one album there whereas the Greatest Hits compilation followed a few months later to number-two on the German charts, despite all similarities with The Very Best album. Also included on Greatest Hits was a new single, "Fernando", which went to number-one in at least thirteen countries worldwide, including the United Kingdom, Germany and Australia, and the single went on to sell over 10 million copies worldwide. In Australia, the song occupied the top position for 14 weeks (and stayed in the chart for 40 weeks), tying with the Beatles' "Hey Jude" for longest-running number-one, and making "Fernando" one of the best-selling singles of all time in Australia. That same year, the group received its first international prize, with "Fernando" being chosen as the "Best Studio Recording of 1975". In the United States, "Fernando" reached the Top 10 of the Cashbox Top 100 singles chart and number 13 on the Billboard Hot 100. It also topped the Billboard Adult Contemporary chart, ABBA's first American number-one single on any chart. The group's fourth studio album, Arrival, a number-one best-seller in Europe and Australia, represented a new level of accomplishment in both songwriting and studio work, prompting rave reviews from more rock-oriented UK music weeklies such as Melody Maker and New Musical Express, and mostly appreciative notices from US critics. Hit after hit flowed from Arrival: "Money, Money, Money", another number-one in Germany and Australia, and "Knowing Me, Knowing You", ABBA's sixth consecutive German number-one as well as another UK number-one. The real sensation was "Dancing Queen", not only topping the charts in loyal markets the UK, Germany and Australia, but also reaching number-one in the United States. In South Africa, ABBA had astounding success with "Fernando", "Dancing Queen" and "Knowing Me, Knowing You" being among the top 20 best-selling singles for 1976–77. In 1977, Arrival was nominated for the inaugural BRIT Award in the category "Best International Album of the Year". By this time ABBA were popular in the United Kingdom, most of Western Europe, Australia and New Zealand. In Frida – The DVD, Lyngstad explains how she and Fältskog developed as singers, as ABBA's recordings grew more complex over the years. The band's popularity in the United States would remain on a comparatively smaller scale, and "Dancing Queen" became the only Billboard Hot 100 number-one single ABBA had there (they did, however, get three more singles to the number-one position on other Billboard charts, including Billboard Adult Contemporary and Hot Dance Club Play). Nevertheless, Arrival finally became a true breakthrough release for ABBA on the US album market where it peaked at number 20 on the Billboard 200 chart and was certified gold by RIAA. ==== European and Australian tour ==== In January 1977, ABBA embarked on their first major tour. The group's status had changed dramatically and they were clearly regarded as superstars. They opened their much anticipated tour in Oslo, Norway, on 28 January, and mounted a lavishly produced spectacle that included a few scenes from their self-written mini-operetta The Girl with the Golden Hair. The concert attracted immense media attention from across Europe and Australia. They continued the tour through Western Europe, visiting Gothenburg, Copenhagen, Berlin, Cologne, Amsterdam, Antwerp, Essen, Hanover, and Hamburg and ending with shows in the United Kingdom in Manchester, Birmingham, Glasgow and two sold-out concerts at London's Royal Albert Hall. Tickets for these two shows were available only by mail application and it was later revealed that the box-office received 3.5 million requests for tickets, enough to fill the venue 580 times. Along with praise ("ABBA turn out to be amazingly successful at reproducing their records", wrote Creem), there were complaints that "ABBA performed slickly...but with a zero personality coming across from a total of 16 people on stage" (Melody Maker). One of the Royal Albert Hall concerts was filmed as a reference for the filming of the Australian tour for what became ABBA: The Movie, though it is not exactly known how much of the concert was filmed. After the European leg of the tour, in March 1977, ABBA played 11 dates in Australia before a total of 160,000 people. The opening concert in Sydney at the Sydney Showground on 3 March to an audience of 20,000 was marred by torrential rain with Lyngstad slipping on the wet stage during the concert. However, all four members would later recall this concert as the most memorable of their career. Upon their arrival in Melbourne, a civic reception was held at the Melbourne Town Hall and ABBA appeared on the balcony to greet an enthusiastic crowd of 6,000. In Melbourne, the group played three concerts at the Sidney Myer Music Bowl with 14,500 at each including the Australian Prime Minister Malcolm Fraser and his family. At the first Melbourne concert, an additional 16,000 people gathered outside the fenced-off area to listen to the concert. In Adelaide, the group performed one concert at West Lakes Football Stadium in front of 20,000 people, with another 10,000 listening outside. During the first of five concerts in Perth, there was a bomb scare with everyone having to evacuate the Entertainment Centre. The trip was accompanied by mass hysteria and unprecedented media attention ("Swedish ABBA stirs box-office in Down Under tour...and the media coverage of the quartet rivals that set to cover the upcoming Royal tour of Australia", wrote Variety), and is captured on film in ABBA: The Movie, directed by Lasse Hallström. The Australian tour and its subsequent ABBA: The Movie produced some ABBA lore, as well. Fältskog's blonde good looks had long made her the band's "pin-up girl", a role she disdained. During the Australian tour, she performed in a skin-tight white jumpsuit, causing one Australian newspaper to use the headline "Agnetha's bottom tops dull show". When asked about this at a news conference, she replied: "Don't they have bottoms in Australia?"In December 1977, ABBA followed up Arrival with the more ambitious fifth album ABBA: The Album, released to coincide with the debut of ABBA: The Movie. Although the album was less well received by UK reviewers, it did spawn more worldwide hits: "The Name of the Game" and "Take a Chance on Me", which both topped the UK charts, and peaked at number 12 and number three, respectively, on the Billboard Hot 100 chart in the US. Although "Take a Chance on Me" did not top the American charts, it proved to be ABBA's biggest hit single there, selling more copies than "Dancing Queen". The Album also included "Thank You for the Music", the B-side of "Eagle" in countries where the latter had been released as a single, and was belatedly released as an A-side single in the United Kingdom and Ireland in 1983. "Thank You for the Music" has become one of the best loved and best known ABBA songs without being released as a single during the group's lifetime. ==== Polar Music Studio formation ==== By 1978 ABBA were one of the biggest bands in the world. They converted a vacant cinema into the Polar Music Studio, a state-of-the-art studio in Stockholm. The studio was used by several other bands; notably Genesis' Duke and Led Zeppelin's In Through the Out Door were recorded there. During May, the group went to the United States for a promotional campaign, performing alongside Andy Gibb on Olivia Newton-John's TV show. Recording sessions for the single "Summer Night City" were an uphill struggle, but upon release the song became another hit for the group. The track would set the stage for ABBA's foray into disco with their next album.On 9 January 1979, the group performed "Chiquitita" at the Music for UNICEF Concert held at the United Nations General Assembly to celebrate UNICEF's Year of the Child. ABBA donated the copyright of this worldwide hit to the UNICEF; see Music for UNICEF Concert. The single was released the following week, and reached number-one in ten countries. ==== North American and European tours ==== In mid-January 1979, Ulvaeus and Fältskog announced they were getting divorced. The news caused interest from the media and led to speculation about the band's future. ABBA assured the press and their fan base they were continuing their work as a group and that the divorce would not affect them. Nonetheless, the media continued to confront them with this in interviews. To escape the media swirl and concentrate on their writing, Andersson and Ulvaeus secretly travelled to Compass Point Studios in Nassau, Bahamas, where for two weeks they prepared their next album's songs. The group's sixth studio album, Voulez-Vous, was released in April 1979, the title track of which was recorded at the famous Criteria Studios in Miami, Florida, with the assistance of recording engineer Tom Dowd amongst others. The album topped the charts across Europe and in Japan and Mexico, hit the Top 10 in Canada and Australia and the Top 20 in the United States. None of the singles from the album reached number-one on the UK charts, but "Chiquitita", "Does Your Mother Know", "Angeleyes" (with "Voulez-Vous", released as a double A-side) and "I Have a Dream" were all UK Top 5 hits. In Canada, "I Have a Dream" became ABBA's second number-one on the RPM Adult Contemporary chart (after "Fernando" hit the top previously). Also in 1979, the group released their second compilation album, Greatest Hits Vol. 2, which featured a brand new track: "Gimme! Gimme! Gimme! (A Man After Midnight)", another number-three hit in both the UK and Germany. In Russia during the late 1970s, the group was paid in oil commodities because of an embargo on the ruble.On 13 September 1979, ABBA began ABBA: The Tour at Northlands Coliseum in Edmonton, Canada, with a full house of 14,000. "The voices of the band, Agnetha's high sauciness combined with round, rich lower tones of Anni-Frid, were excellent...Technically perfect, melodically correct and always in perfect pitch...The soft lower voice of Anni-Frid and the high, edgy vocals of Agnetha were stunning", raved Edmonton Journal. During the next four weeks they played a total of 17 sold-out dates, 13 in the United States and four in Canada. The last scheduled ABBA concert in the United States in Washington, D.C. was cancelled due to Fältskog's emotional distress suffered during the flight from New York to Boston, when the group's private plane was subjected to extreme weather conditions and was unable to land for an extended period. They appeared at the Boston Music Hall for the performance 90 minutes late. The tour ended with a show in Toronto, Canada at Maple Leaf Gardens before a capacity crowd of 18,000. "ABBA plays with surprising power and volume; but although they are loud, they're also clear, which does justice to the signature vocal sound...Anyone who's been waiting five years to see Abba will be well satisfied", wrote Record World. On 19 October 1979, the tour resumed in Western Europe where the band played 23 sold-out gigs, including six sold-out nights at London's Wembley Arena. ==== Progression ==== In March 1980, ABBA travelled to Japan where upon their arrival at Narita International Airport, they were besieged by thousands of fans. The group played eleven concerts to full houses, including six shows at Tokyo's Budokan. This tour was the last "on the road" adventure of their career. In the middle of 1980, the group released the single "The Winner Takes It All" the group's eighth UK chart topper (and their first since 1978). The song is widely misunderstood as being written about Ulvaeus and Fältskog's marital tribulations; Ulvaeus wrote the lyrics, but has stated they were not about his own divorce; Fältskog has repeatedly stated she was not the loser in their divorce. In the United States, the single peaked at number-eight on the Billboard Hot 100 chart and became ABBA's second Billboard Adult Contemporary number-one. It was also re-recorded by Andersson and Ulvaeus with a slightly different backing track, by French chanteuse Mireille Mathieu at the end of 1980 – as "Bravo tu as gagné", with French lyrics by Alain Boublil. November the same year saw the release of ABBA's seventh album Super Trouper, which reflected a certain change in ABBA's style with more prominent use of synthesizers and increasingly personal lyrics. It set a record for the most pre-orders ever received for a UK album after one million copies were ordered before release. The second single from the album, "Super Trouper", also hit number-one in the UK, becoming the group's ninth and final UK chart-topper. Another track from the Super Trouper album, "Lay All Your Love on Me", released in 1981 as a 12-inch (300 mm) single only in selected territories, managed to top the Billboard Hot Dance Club Play chart and peaked at number-seven on the UK singles chart becoming, at the time, the highest ever charting 12-inch (300 mm) release in UK chart history. Also in 1980, ABBA recorded a compilation of Spanish-language versions of their hits called Gracias Por La Música. This was released in Spanish-speaking countries as well as in Japan and Australia. The album became a major success, and along with the Spanish version of "Chiquitita", this signalled the group's breakthrough in Latin America. ABBA Oro: Grandes Éxitos, the Spanish equivalent of ABBA Gold: Greatest Hits, was released in 1999. === 1981–1982: Final album and performances === In January 1981, Ulvaeus married Lena Källersjö, and manager Stig Anderson celebrated his 50th birthday with a party. For this occasion, ABBA recorded the track "Hovas Vittne" (a pun on the Swedish name for Jehovah's Witness and Anderson's birthplace, Hova) as a tribute to him, and released it only on 200 red vinyl copies, to be distributed to the guests attending the party. This single has become a sought-after collectible. In mid-February 1981, Andersson and Lyngstad announced they were filing for divorce. Information surfaced that their marriage had been an uphill struggle for years, and Benny had already met another woman, Mona Nörklit, whom he married in November 1981. Andersson and Ulvaeus had songwriting sessions in early 1981, and recording sessions began in mid-March. At the end of April, the group recorded a TV special, Dick Cavett Meets ABBA with the US talk show host Dick Cavett. The Visitors, ABBA's eighth and final studio album, showed a songwriting maturity and depth of feeling distinctly lacking from their earlier recordings but still placing the band squarely in the pop genre, with catchy tunes and harmonies. Although not revealed at the time of its release, the album's title track, according to Ulvaeus, refers to the secret meetings held against the approval of totalitarian governments in Soviet-dominated states, while other tracks address topics like failed relationships, the threat of war, ageing, and loss of innocence. The album's only major single release, "One of Us", proved to be the last of ABBA's nine number-one singles in Germany, this being in December 1981; and the swansong of their sixteen Top 5 singles on the South African chart. "One of Us" was also ABBA's final Top 3 hit in the UK, reaching No. 1 on some charts (such as Record Mirror). Although it topped the album charts across most of Europe, including Ireland, the UK and Germany, The Visitors was not as commercially successful as its predecessors, showing a commercial decline in previously loyal markets such as France, Australia and Japan. A track from the album, "When All Is Said and Done", was released as a single in North America, Australia and New Zealand, and fittingly became ABBA's final Top 40 hit in the US (debuting on the US charts on 31 December 1981), while also reaching the US Adult Contemporary Top 10, and number-four on the RPM Adult Contemporary chart in Canada. The song's lyrics, as with "The Winner Takes It All" and "One of Us", dealt with the painful experience of separating from a long-term partner, though it looked at the trauma more optimistically. With the now publicised story of Andersson and Lyngstad's divorce, speculation increased of tension within the band. Also released in the United States was the title track of The Visitors, which hit the Top Ten on the Billboard Hot Dance Club Play chart. ==== Final recording sessions ==== In the spring of 1982, songwriting sessions had started and the group came together for more recordings. Plans were not completely clear, but a new album was discussed and the prospect of a small tour suggested. The recording sessions in May and June 1982 were a struggle, and only three songs were eventually recorded: "You Owe Me One", "I Am the City" and "Just Like That". Andersson and Ulvaeus were not satisfied with the outcome, so the tapes were shelved and the group took a break for the summer.Back in the studio again in early August, the group had changed plans for the rest of the year: they settled for a Christmas release of a double album compilation of all their past single releases to be named The Singles: The First Ten Years. New songwriting and recording sessions took place, and during October and December, they released the singles "The Day Before You Came"/"Cassandra" and "Under Attack"/"You Owe Me One", the A-sides of which were included on the compilation album. Neither single made the Top 20 in the United Kingdom, though "The Day Before You Came" became a Top 5 hit in many European countries such as Germany, the Netherlands and Belgium. The album went to number-one in the UK and Belgium, Top 5 in the Netherlands and Germany and Top 20 in many other countries. "Under Attack", the group's final release before disbanding, was a Top 5 hit in the Netherlands and Belgium. "I Am the City" and "Just Like That" were left unreleased on The Singles: The First Ten Years for possible inclusion on the next projected studio album, though this never came to fruition. "I Am the City" was eventually released on the compilation album More ABBA Gold in 1993, while "Just Like That" has been recycled in new songs with other artists produced by Andersson and Ulvaeus. A reworked version of the verses ended up in the musical Chess. The chorus section of "Just Like That" was eventually released on a retrospective box set in 1994, as well as in the ABBA Undeleted medley featured on disc 9 of The Complete Studio Recordings. Despite a number of requests from fans, Ulvaeus and Andersson are still refusing to release ABBA's version of "Just Like That" in its entirety, even though the complete version surfaced on bootlegs. The group travelled to London to promote The Singles: The First Ten Years in the first week of November 1982, appearing on Saturday Superstore and The Late, Late Breakfast Show, and also to West Germany in the second week, to perform on Show Express. On 19 November 1982, ABBA appeared for the last time in Sweden on the TV programme Nöjesmaskinen, and on 11 December 1982, they made their last performance ever, transmitted to the UK on Noel Edmonds' The Late, Late Breakfast Show, through a live link from a TV studio in Stockholm. ==== Final performances ==== Andersson and Ulvaeus began collaborating with Tim Rice in early 1983 on writing songs for the musical project Chess, while Fältskog and Lyngstad both concentrated on international solo careers. While Andersson and Ulvaeus were working on the musical, a further co-operation among the three of them came with the musical Abbacadabra that was produced in France for television. It was a children's musical utilising 14 ABBA songs. Alain and Daniel Boublil, who wrote Les Misérables, had been in touch with Stig Anderson about the project, and the TV musical was aired over Christmas on French TV and later a Dutch version was also broadcast. Boublil previously also wrote the French lyric for Mireille Mathieu's version of "The Winner Takes It All". Anni-Frid Lyngstad, who had recently moved to Paris, participated in the French version, and recorded a single, "Belle", a duet with French singer Daniel Balavoine. The song was a cover of ABBA's 1976 instrumental track "Arrival". As the single "Belle" sold well in France, Cameron Mackintosh wanted to stage an English-language version of the show in London, with the French lyrics translated by David Wood and Don Black; Andersson and Ulvaeus got involved in the project, and contributed with one new song, "I Am the Seeker". "Abbacadabra" premiered on 8 December 1983 at the Lyric Hammersmith Theatre in London, to mixed reviews and full houses for eight weeks, closing on 21 January 1984. Lyngstad was also involved in this production, recording "Belle" in English as "Time", a duet with actor and singer B. A. Robertson: the single sold well, and was produced and recorded by Mike Batt. A year later, Lyngstad performed "I Have A Dream" with a children's choir at the United Nations Organisation Gala, in May 1984 at Geneva, Switzerland.All four members made their (at the time, their final) public appearance as four friends more than as ABBA in January 1986, when they recorded a video of themselves performing an acoustic version of "Tivedshambo" (which was the first song written by their manager Stig Anderson), for a Swedish TV show honouring Anderson on his 55th birthday. The four had not seen each other for more than two years. That same year they also performed privately at another friend's 40th birthday: their old tour manager, Claes af Geijerstam. They sang a self-written song titled "Der Kleine Franz" that was later to resurface in Chess. Also in 1986, ABBA Live was released, featuring selections of live performances from the group's 1977 and 1979 tours. The four members were guests at the 50th birthday of Görel Hanser in 1999. Hanser was a long-time friend of all four, and also former secretary of Stig Anderson. Honouring Görel, ABBA performed a Swedish birthday song "Med En Enkel Tulipan" a cappella.Benny Andersson has on several occasions performed old ABBA songs. In June 1992, he and Ulvaeus appeared with U2 at a Stockholm concert, singing the chorus of "Dancing Queen", and a few years later during the final performance of the B & B in Concert in Stockholm, Andersson joined the cast for an encore at the piano. Andersson frequently adds an ABBA song to the playlist when he performs with his BAO band. He also played the piano during new recordings of the ABBA songs "Like an Angel Passing Through My Room" with opera singer Anne Sofie von Otter, and "When All Is Said and Done" with Swede Viktoria Tolstoy. In 2002, Andersson and Ulvaeus both performed an a cappella rendition of the first verse of "Fernando" as they accepted their Ivor Novello award in London. Lyngstad performed and recorded an a cappella version of "Dancing Queen" with the Swedish group the Real Group in 1993, and also re-recorded "I Have a Dream" with Swiss singer Dan Daniell in 2003. ==== Permanent break ==== ABBA has never officially announced the end of the group, but it has long been considered dissolved. Their final public performance together as ABBA was on the British TV programme The Late, Late Breakfast Show (live from Stockholm) on 11 December 1982. While reminiscing on "The Day Before You Came", Ulvaeus said: "we might have continued for a while longer if that had been a number one". In January 1983, Fältskog started recording sessions for a solo album, as Lyngstad had successfully released her album Something's Going On some months earlier. Ulvaeus and Andersson, meanwhile, started songwriting sessions for the musical Chess. In interviews at the time, Björn and Benny denied the split of ABBA ("Who are we without our ladies? Initials of Brigitte Bardot?"), and Lyngstad and Fältskog kept claiming in interviews that ABBA would come together for a new album repeatedly during 1983 and 1984. Internal strife between the group and their manager escalated and the band members sold their shares in Polar Music during 1983. Except for a TV appearance in 1986, the foursome did not come together publicly again until they were reunited at the Swedish premiere of the Mamma Mia! movie on 4 July 2008. In an interview with the Sunday Telegraph, following the premiere, Ulvaeus and Andersson confirmed that there was nothing that could entice them back on stage again. Ulvaeus said: "We will never appear on stage again. [...] There is simply no motivation to re-group. Money is not a factor and we would like people to remember us as we were. Young, exuberant, full of energy and ambition. I remember Robert Plant saying Led Zeppelin were a cover band now because they cover all their own stuff. I think that hit the nail on the head." However, on 3 January 2011, Fältskog, who has been long considered to be the most reclusive member of the group and a major obstacle to any reunion, raised the possibility of reuniting for a one-off engagement. She admitted that she has not yet brought the idea up to the other three members. In April 2013, she reiterated her hopes for reunion during an interview with Die Zeit, stating: "If they ask me, I'll say yes."In a May 2013 interview, Fältskog, aged 63 at the time, confirmed that an ABBA reunion will never occur: "I think we have to accept that it will not happen, because we are too old and each one of us has their own life. Too many years have gone by since we stopped, and there's really no meaning in putting us together again." Fältskog further explained that the band members remained on amicable terms: "It's always nice to see each other now and then and to talk a little and to be a little nostalgic." In an April 2014 interview, Fältskog, when asked about whether the band might reunite for a new recording said: "It's difficult to talk about this because then all the news stories will be: 'ABBA is going to record another song!' But as long as we can sing and play, then why not? I would love to, but it's up to Björn and Benny." === 2016–present: Reunion and upcoming hologram project === On 20 January 2016, all four original members of ABBA made a public appearance at Mamma Mia the Party in Stockholm.On 6 June 2016, the four members of ABBA appeared together at a private party at Berns Salonger in Stockholm, which was held to celebrate the 50th anniversary of Andersson and Ulvaeus' first meeting. Fältskog and Lyngstad sang the ABBA song "The Way Old Friends Do" before they were joined on stage by Andersson and Ulvaeus. British manager Simon Fuller announced in a statement in October 2016 that the group would be reuniting to work on a new 'digital entertainment experience'. The project will feature the members in their "life-like" hologram form based on their late 1970s tour and is set to launch by the spring of 2019. On 27 April 2018, the members announced that they had recorded two new songs, with one titled "I Still Have Faith in You", to feature in a TV special set to air later in the year. The other new track is called "Don't Shut Me Down". === Solo careers === ==== Benny Andersson and Björn Ulvaeus ==== In October 1984, Ulvaeus and Andersson together with lyricist Tim Rice released the musical concept double-album Chess. The singles "One Night in Bangkok" (with vocals by Murray Head and Anders Glenmark ) and "I Know Him So Well" (a duet by Barbara Dickson and Elaine Paige, and later also recorded by both Barbra Streisand and Whitney Houston) were both hugely successful. The former reached number-one in Australia, Germany, Spain and Switzerland; number-two in Austria, France and New Zealand; number-three in Canada, Norway, Sweden and the US, as well as reaching the top 10 in a few other countries. In May 1986, the musical premiered in London's West End, and ran for almost three years. Chess also opened on Broadway in April 1988, but closed within two months due to bad reviews. In Stockholm, the composers staged Chess på svenska (Chess in Swedish) in 2003, with some new material, including the musical numbers "Han är en man, han är ett barn" ("He's a Man, He's a Child") and "Glöm mig om du kan" ("Forget Me If You Can"). In 2008, the musical was again revived for a successful staging at London's Royal Albert Hall which was subsequently released on DVD, and then in two successful separate touring productions in the United States and United Kingdom, in 2010. Andersson and Ulvaeus' next project, Kristina från Duvemåla, an epic Swedish musical, premiered in Malmö, in southern Sweden in October 1995. The musical ran for five years in Stockholm, and an English version has been in development for some considerable time. It has been reported that a Broadway production is in its earliest stages of pre-production. In the meantime, following some earlier workshops, a full presentation of the English translation of the musical in concert, now with the shortened name of "Kristina", took place to capacity crowds in September 2009 at New York's Carnegie Hall, and in April 2010 at London's Royal Albert Hall, followed by a CD release of the New York recordings. Since 1983, besides Chess and Kristina från Duvemåla, Benny Andersson has continued writing songs with Ulvaeus. The pair produced two English-language pop albums with Swedish duo Gemini in 1985 and 1987. In 1987, Andersson also released his first solo album on his own label, Mono Music, called "Klinga mina klockor" ("Ring My Bells"), all new material inspired by Swedish folk music – and followed it with his second album titled November 1989. During the 1990s, Andersson wrote music for the popular Swedish cabaret quartet Ainbusk Singers, giving them two hits: "Lassie" and "Älska mig" ("Love me"), and later produced Shapes, an English-language album by group's Josefin Nilsson with all-new material by Andersson and Ulvaeus. Andersson has also regularly written music for films (most notably to Roy Andersson's Songs from the Second Floor). In 2001, Andersson formed his own band, Benny Anderssons Orkester (BAO), which released three successful albums in 2001, 2004 and 2007. Andersson has the distinction of remaining the longest in the Swedish Radio Svensktoppen charts; the song "Du är min man" ("You Are My Man"), sung by Helen Sjöholm, spent 278 weeks there between 2004 and 2009. Andersson released his third album BAO 3 in October 2007, of new material with his band BAO and vocalists Helen Sjöholm and Tommy Körberg, as well as playing to full houses at two of Sweden's largest concert venues in October and November 2007, with an audience of 14,000. Ulvaeus has not appeared on stage performing music since ABBA, but had a reunion with his co-members of the Hootenanny Singers on 16 July 2005 at a music festival in his hometown of Västervik, singing their 1966 hit "Marianne". Andersson and Ulvaeus have been highly involved in the worldwide productions of the musical Mamma Mia!, alongside Lyngstad who attends premieres. They were also involved in the production of the successful film version of the musical, which opened in July 2008. Andersson produced the soundtrack utilising many of the musicians ABBA used on their albums and tours. Andersson made a cameo appearance in the movie as a "fisherman" piano player in the "Dancing Queen" scene, while Ulvaeus is seen as a Greek god playing a lyre during the closing credits. Andersson and Ulvaeus have continuously been writing new material; most recently the two wrote seven songs for Anderssons BAO 2011 album 'O Klang Och Jubeltid', performed as usual by vocalists Sjöholm, Körberg and Moreus. In July 2009, BAO released their first international release, now named the Benny Andersson Band, with the album The Story of a Heart. The album was a compilation of 14 tracks from Andersson's five Swedish-language releases between 1987 and 2007, including five songs now recorded with lyrics by Ulvaeus in English, and the new title song premiered on BBC2's Ken Bruce Show. A Swedish-language version of the title track, "Sommaren Du Fick" ("The Summer You Got"), was released as a single in Sweden prior to the English version, with vocals by Helen Sjöholm. In May 2009, Andersson also released a single recorded by the staff at his privately owned Stockholm hotel Hotel Rival, titled "2nd Best to None", accompanied by a video showing the staff at work. In 2008, Andersson and Ulvaeus wrote a song for Swedish singer Sissela Kyle, titled "Jag vill bli gammal" ("I Wanna Grow Old"), for her Stockholm stage show "Your Days Are Numbered", which was never recorded and released, but did get a TV performance. Ulvaeus also contributed lyrics to ABBA's 1976 instrumental track "Arrival" for Sarah Brightman's cover version recorded for her 2008 album Winter Symphony. New English lyrics have also been written for Andersson's 1999 song "Innan Gryningen" (then also named "Millennium Hymn"), with the new title "The Silence of the Dawn" for Barbara Dickson (performed live, but not yet recorded and released). In 2007, they wrote the new song "Han som har vunnit allt" ("He Who's Won It All") for actor/singer Anders Ekborg. Björn wrote English lyrics for two older songs from Benny's solo albums: "I Walk with You Mama" ("Stockholm by Night", 1989) and "After the Rain" ("Efter regnet", 1987) for opera singer Anne Sofie von Otter, for her Andersson tribute album I Let the Music Speak. Barbara Dickson recorded (but not yet released) a Björn & Benny song called "The Day The Wall Came Tumbling Down"; the song eventually was released by Australian Mamma Mia! musical star Anne Wood 201 album of ABBA covers, Divine Discontent. As of October 2012, Björn Ulvaeus has mentioned writing new material with Benny for a BAO Christmas release (also mentioned as a BAO 'box'), and Benny is busy writing music for a Swedish language obscure musical, "Hjälp Sökes" ("Help Wanted") together with Kristina Lugn and Lars Rudolfsson, premiering 8 February 2013. Andersson has also written music for a documentary film about Olof Palme, re-recording the track "Sorgmarsch" ("Dirge") from his last album throughout the film. ==== Agnetha Fältskog and Anni-Frid Lyngstad ==== Both female members of ABBA pursued solo careers on the international scene after their work with the group. In 1982, Lyngstad chose Genesis drummer and vocalist Phil Collins to produce the album Something's Going On and unveiled the hit single and video "I Know There's Something Going On" in August of that year. The single became a number-one hit in France (where it spent five weeks at the top), Belgium, Switzerland and Costa Rica. The track reached number-three in Austria, the Netherlands, Norway, Sweden and Poland, and was also a Top 10 hit in Germany, Italy, Finland, South Africa and Australia. The track also proved successful in the USA, peaking at No. 13 (and spending almost four months on the Billboard Hot 100). Sveriges Television documented this historical event, by filming the whole recording process. The result became a one-hour TV documentary, including interviews with Lyngstad, Collins, Ulvaeus and Andersson as well as all the musicians. This documentary and the promotion videos from the album are included in Frida – The DVD. Lyngstad's second solo album after ABBA was called Shine, produced by Steve Lillywhite. Shine was recorded in Paris and released in 1984. Shine was Lyngstad's final studio album release for twelve years. It featured "Slowly", the last known Andersson-Ulvaeus composition to have been recorded by one of the former female ABBA vocalists to date. The promotion videos and clips for "Shine" are included in Frida – The DVD. In 1980, Agnetha Fältskog and her then-7-year-old daughter Linda recorded Nu tändas tusen juleljus, a Swedish Christmas album. Released in 1981, it was Fältskog's first Swedish-language recording for the Polar Music label after she left CBS-Cupol. It peaked at No. 6 on the Swedish album chart in January 1982, has been re-released on CD by Polar Music/PolyGram/Universal Music in the 1990s and 2000s, and is one of the best-selling Swedish Christmas albums of all time. The album title is derived from one of Scandinavia's best-known Christmas carols, "Nu tändas tusen juleljus" (Now a thousand Christmas candles are lit). In 1983, Fältskog released the solo album Wrap Your Arms Around Me which achieved platinum sales in Sweden. This included the single "The Heat Is On", which was a hit all over Europe and Scandinavia. It reached number-one in Sweden and Norway and number-two in the Netherlands and Belgium. In the United States, Fältskog earned a Billboard Top 30 hit with "Can't Shake Loose". The single "Wrap Your Arms Around Me" was another successful hit, topping the charts in Belgium and Denmark, reaching the Top 5 in Sweden, the Netherlands and South Africa, and the Top 20 in Germany and France. The album sold 1.2 million copies worldwide. The album was produced by the highly successful producer and songwriter Mike Chapman, also known for his work with the Sweet, Mud, Suzi Quatro, Blondie, Pat Benatar and the Knack. "It's So Nice to be Rich" was Agnetha's fourth top ten hit in Sweden in 1983. Her duet with Tomas Ledin, "Never Again", was the first. Fältskog's second English-language solo album, Eyes of a Woman, was released in March 1985. It peaked at number two in Sweden (becoming a platinum seller), and performing reasonably well in Europe. The album was produced by Eric Stewart of 10cc. The first single from the album was her self-penned "I Won't Let You Go". Agnetha's duet with Ola Håkansson, "The Way You Are", was a number-one hit in Sweden in 1986 and was awarded double platinum status. In early 1987, Agnetha recorded an album "Kom följ med i vår karusell" ("Come Join Us on Our Carousel') with her son Christian. The album contained songs for children and was sung in Swedish. For the album Agnetha recorded duets with her son and with a choir of children. She also recorded a few solo songs. The single "På Söndag" ("On Sunday") was much played at the radio and even made the Swedish top 10, unique for a song made for kids to enjoy. Also in 1987, Fältskog released her third post-ABBA solo album, the Peter Cetera-produced I Stand Alone, which also included the Billboard Adult Contemporary duet with Cetera, "I Wasn't the One (Who Said Goodbye)", as well as the European charting singles "The Last Time" and "Let It Shine". The album was extremely successful in Sweden, where it spent eight weeks at number-one and was awarded double-platinum. Shortly after some minor European promotion for the album in early 1988, Fältskog withdrew from public life and halted her music career. In 1996, she released her autobiography, As I Am, and a compilation album featuring her solo hits alongside some ABBA classics. In 2004, she made a successful comeback, when she released the critically acclaimed album My Colouring Book containing 1960s covers who had the most impact on her teenage years as a music contender. It debuted at number-one in Sweden (achieving triple-platinum status), number-six in Germany, and number 12 in the UK, winning a silver award, and achieving gold status in Finland. The single "If I Thought You'd Ever Change Your Mind" (a cover of the Cilla Black 1960s song) became Fältskog's biggest solo hit in the United Kingdom, reaching number 11. The single peaked at number-two in Sweden and was a hit throughout Scandinavia and Europe. A further single, "When You Walk in the Room", was released but met with less success, only peaking at number 34 in the United Kingdom. In January 2007, she sang a live duet on stage with Swedish singer Tommy Körberg at the after party for the final performance of the musical, Mamma Mia!, in Stockholm, at which Benny Andersson and Björn Ulvaeus were also present. In 1992, Lyngstad had been asked and chosen to be the chairperson for the environmental organisation "Artister för miljön" (Artists for the Environment) in Sweden. She became chairperson for this organisation from 1992 to 1995. To mark her interests for the environment, she recorded the Julian Lennon song "Saltwater" and performed it live in Stockholm. She arranged and financed summer camps for poor children in Sweden, focusing on environmental and ecological issues. Her environmental work for this organisation led up to the decision to record again. The album Djupa andetag (Deep Breaths) was released towards the end of 1996 and became a success in Sweden, where it reached number-one. The lyrics for the single from this album, "Även en blomma" ("Even a Flower"), deal with environmental issues. In 2004, Lyngstad recorded a song called "The Sun Will Shine Again", written especially for her and released with former Deep Purple member Jon Lord. The couple made several TV performances with this song in Germany. Lyngstad lives a relatively low-profile life but occasionally appears at a party or charity function. On 26 August 1992, she married Prince Heinrich Ruzzo Reuss von Plauen, of the German Reuss family. Reuss von Plauen died of lymphoma in 1999 at the age of 49. In addition to losing her husband, Lyngstad had also lost her daughter Lise-Lotte in a car crash a year earlier. On 5 December 2005, Universal released her box set, Frida – 4xCD 1xDVD, consisting of the solo albums she recorded for the Polar Label and the 3​1⁄2-hour documentary Frida – The DVD. On this DVD, which covers her entire singing career, the viewer is guided by Lyngstad herself through the years from her TV debut in Sweden in 1967 to the TV performances she made in Germany in 2004. Many rare clips are included in the set and each performance is explained by Lyngstad herself. The interview with Lyngstad was filmed in the Swiss Alps in mid-2005. Lyngstad returned to the recording studio in 2010 to record vocals for the Cat Stevens song "Morning Has Broken", for Swedish guitarist Georg Wadenius's October 2010 album Reconnection. The album, which featured other guest vocalists, reached number 17 in the Swedish charts.In May 2013, Fältskog released a solo album entitled A through Universal International. In a promotional interview, Fältskog explained that the album was unplanned and it was after she heard the first three songs that she felt that she "had to do this [record the album]". She also revealed that she completed singing lessons prior to recording A, as she felt "a bit rusty" in her throat. Fältskog stated that she would not be undertaking any tours or live performances in support of the album, explaining: "I'm not that young anymore. I don’t have the energy to do that, and also I don’t want to travel too much." The title of the album was conceived of by the studio production team. A has been very successful, earning her four Gold Records in the UK (where it peaked at number-six), Australia, Germany and Sweden. In the UK and Australia, A was in the top 100 albums of 2013. === Resurgence of public interest === The same year the members of ABBA went their separate ways, the French production of a "tribute" show (a children's TV musical named Abbacadabra using 14 ABBA songs) spawned new interest in the group's music. After receiving little attention during the mid-to-late-1980s, ABBA's music experienced a resurgence in the early 1990s due to the UK synth-pop duo Erasure, who released a cover extended play featuring versions of ABBA songs which topped the charts in 1992. As U2 arrived in Stockholm for a concert in June of that year, the band paid homage to ABBA by inviting Björn Ulvaeus and Benny Andersson to join them on stage for a rendition of "Dancing Queen", playing guitar and keyboards. September 1992 saw the release of ABBA Gold: Greatest Hits, a new compilation album. The single "Dancing Queen" received radio airplay in the UK in the middle of 1992 to promote the album. The song returned to the Top 20 of the UK singles chart in August that year, this time peaking at number 16. The enormous interest in the ABBA Gold: Greatest Hits compilation saw the release of More ABBA Gold: More ABBA Hits in 1993. In 1994, two Australian cult films caught the attention of the world's media, both focusing on admiration for ABBA: The Adventures of Priscilla, Queen of the Desert and Muriel's Wedding. The same year, Thank You for the Music, a four-disc box set comprising all the group's hits and stand-out album tracks, was released with the involvement of all four members. "By the end of the twentieth century", American critic Chuck Klosterman wrote a decade later, "it was far more contrarian to hate ABBA than to love them."ABBA were soon recognised and embraced by other acts: Evan Dando of the Lemonheads recorded a cover version of "Knowing Me, Knowing You"; Sinéad O'Connor and Boyzone's Stephen Gately have recorded "Chiquitita"; Tanita Tikaram, Blancmange and Steven Wilson paid tribute to "The Day Before You Came". Cliff Richard covered "Lay All Your Love on Me", while Dionne Warwick, Peter Cetera, and Celebrity Skin recorded their versions of "SOS". US alternative-rock musician Marshall Crenshaw has also been known to play a version of "Knowing Me, Knowing You" in concert appearances, while legendary English Latin pop songwriter Richard Daniel Roman has recognised ABBA as a major influence. Swedish metal guitarist Yngwie Malmsteen covered "Gimme! Gimme! Gimme! (A Man After Midnight)" with slightly altered lyrics. Two different compilation albums of ABBA songs have been released. ABBA: A Tribute coincided with the 25th anniversary celebration and featured 17 songs, some of which were recorded especially for this release. Notable tracks include Go West's "One of Us", Army of Lovers "Hasta Mañana", Information Society's "Lay All Your Love on Me", Erasure's "Take a Chance on Me" (with MC Kinky), and Lyngstad's a cappella duet with the Real Group of "Dancing Queen". A second 12-track album was released in 1999, entitled ABBAmania, with proceeds going to the Youth Music charity in England. It featured all new cover versions: notable tracks were by Madness ("Money, Money, Money"), Culture Club ("Voulez-Vous"), the Corrs ("The Winner Takes It All"), Steps ("Lay All Your Love on Me", "I Know Him So Well"), and a medley entitled "Thank ABBA for the Music" performed by several artists and as featured on the Brits Awards that same year. In 1997, an ABBA tribute group was formed, the ABBA Teens, which was subsequently renamed the A-Teens to allow the group some independence. The group's first album, "The ABBA Generation", consisting solely of ABBA covers reimagined as 1990s pop songs, was a worldwide success and so were subsequent albums. The group disbanded in 2004 due to a gruelling schedule and intentions to go solo. In Sweden, the growing recognition of the legacy of Andersson and Ulvaeus resulted in the 1998 B & B Concerts, a tribute concert (with Swedish singers who had worked with the songwriters through the years) showcasing not only their ABBA years, but hits both before and after ABBA. The concert was a success, and was ultimately released on CD. It later toured Scandinavia and even went to Beijing in the People's Republic of China for two concerts. In 2000, ABBA was reported to have turned down an offer of approximately US$1,000,000,000 (one billion US dollars) to do a reunion tour consisting of 100 concerts.For the 2004 semi-final of the Eurovision Song Contest, staged in Istanbul 30 years after ABBA had won the contest in Brighton, all four members made cameo appearances in a special comedy video made for the interval act, entitled "Our Last Video Ever". Other well-known stars such as Rik Mayall, Cher and Iron Maiden's Eddie also made appearances in the video. It was not included in the official DVD release of the Eurovision Contest, but was issued as a separate DVD release, retitled The Last Video at the request of the former ABBA members. In 2005, all four members of ABBA appeared at the Stockholm premiere of the musical Mamma Mia!.On 22 October 2005, at the 50th anniversary celebration of the Eurovision Song Contest, "Waterloo" was chosen as the best song in the competition's history.On 4 July 2008, all four ABBA members were reunited at the Swedish premiere of the film Mamma Mia!. It was only the second time all of them had appeared together in public since 1986. During the appearance, they re-emphasised that they intended never to officially reunite, citing the opinion of Robert Plant that the re-formed Led Zeppelin was more like a cover band of itself than the original band. Ulvaeus stated that he wanted the band to be remembered as they were during the peak years of their success. The compilation album ABBA Gold: Greatest Hits, originally released in 1992, returned to number-one in the UK album charts for the fifth time on 3 August 2008. On 14 August 2008, the Mamma Mia! The Movie film soundtrack went to number-one on the US Billboard charts, ABBA's first US chart-topping album. During the band's heyday the highest album chart position they had ever achieved in America was number 14. In November 2008, all eight studio albums, together with a ninth of rare tracks, was released as The Albums. It hit several charts, peaking at number-four in Sweden and reaching the Top 10 in several other European territories. In 2008, Sony Computer Entertainment Europe, in collaboration with Universal Music Group Sweden AB, released SingStar ABBA on both the PlayStation 2 and PlayStation 3 games consoles, as part of the SingStar music video games. The PS2 version features 20 ABBA songs, while 25 songs feature on the PS3 version. On 22 January 2009, Fältskog and Lyngstad appeared together on stage to receive the Swedish music award "Rockbjörnen" (for "lifetime achievement"). In an interview, the two women expressed their gratitude for the honorary award and thanked their fans. On 25 November 2009, PRS for Music announced that the British public voted ABBA as the band they would most like to see re-form.On 27 January 2010, ABBAWORLD, a 25-room touring exhibition featuring interactive and audiovisual activities, debuted at Earls Court Exhibition Centre in London. According to the exhibition's website, ABBAWORLD is "approved and fully supported" by the band members."Mamma Mia" was released as one of the first few non-premium song selections for the online RPG game Bandmaster. On 17 May 2011, "Gimme! Gimme! Gimme!" was added as a non-premium song selection for the Bandmaster Philippines server. On 15 November 2011, Ubisoft released a dancing game called ABBA: You Can Dance for the Wii.In January 2012, Universal Music announced the re-release of ABBA's final album The Visitors, featuring a previously unheard track "From a Twinkling Star to a Passing Angel".A book entitled ABBA: The Official Photo Book was published in early 2014 to mark the 40-year anniversary of the band's Eurovision victory. The book reveals that part of the reason for the band's outrageous costumes was that Swedish tax laws at the time allowed the cost of garish outfits that were not suitable for daily wear to be tax deductible. A sequel to the 2008 movie Mamma Mia!, titled Mamma Mia! Here We Go Again, was announced on 20 May 2017 and then the film was released on 20 July 2018.In June 2017, a blue plaque outside Brighton Dome was set to commemorate their 1974 Eurovision win.On 27 April 2018, ABBA announced that they had recorded two new songs and one of them, "I Still Have Faith in You", would be performed by their digital selves in a TV special produced by NBC and the BBC aimed for broadcasting in December 2018. == Artistry == === Recording process === ABBA were perfectionists in the studio, working on tracks until they got them right rather than leaving them to come back later on.The band created a basic rhythm track with a drummer, guitarist and bass player, and overlaid other arrangements and instruments. Vocals were then added, and orchestra overdubs were usually left until last.Fältskog and Lyngstad contributed ideas at the studio stage. Andersson and Ulvaeus played them in the backing tracks and they made comments and suggestions. According to Fältskog, she and Lyngstad had the final say in how the lyrics were shaped. After vocals and overdubs were done, the band took up to five days to mix a song. === Fashion, style, videos, advertising campaigns === ABBA was widely noted for the colourful and trend-setting costumes its members wore. The reason for the wild costumes was Swedish tax law. The cost of the clothes was deductible only if they could not be worn other than for performances. Choreography by Graham Tainton also contributed to their performance style. The videos that accompanied some of the band's biggest hits are often cited as being among the earliest examples of the genre. Most of ABBA's videos (and ABBA: The Movie) were directed by Lasse Hallström, who would later direct the films My Life as a Dog, The Cider House Rules and Chocolat.ABBA made videos because their songs were hits in many different countries and personal appearances were not always possible. This was also done in an effort to minimise travelling, particularly to countries that would have required extremely long flights. Fältskog and Ulvaeus had two young children and Fältskog, who was also afraid of flying, was very reluctant to leave her children for such a long time. ABBA's manager, Stig Anderson, realised the potential of showing a simple video clip on television to publicise a single or album, thereby allowing easier and quicker exposure than a concert tour. Some of these videos became classics because of the 1970s-era costumes and early video effects, such as the grouping of the band members in different combinations of pairs, overlapping one singer's profile with the other's full face, and the contrasting of one member against another. In 1976, ABBA participated in an advertising campaign to promote the Matsushita Electric Industrial Co.'s brand, National, in Australia. The campaign was also broadcast in Japan. Five commercial spots, each of approximately one minute, were produced, each presenting the "National Song" performed by ABBA using the melody and instrumental arrangements of "Fernando" and revised lyrics. === Political position === In September 2010, band members Andersson and Ulvaeus criticised the right-wing Danish People's Party (DF) for using the ABBA song "Mamma Mia" (with modified lyrics) at rallies. The band threatened to file a lawsuit against the DF, saying they never allowed their music to be used politically and that they had absolutely no interest in supporting the party. Their record label Universal Music later said that no legal action would be taken because an agreement had been reached. == Success in the United States == During their active career, from 1972 to 1982, ABBA placed twenty singles on the Billboard Hot 100, fourteen of which made the top 40 (13 on the Cashbox Top 100) and ten of which made the Top 20 on both charts. A total of four of those singles reached the Top 10, including "Dancing Queen" which reached number-one in April 1977. While "Fernando" and "SOS" did not break the Top 10 on the Billboard Hot 100 chart, reaching number 13 and 15 respectively, they did reach the Top 10 on Cashbox ("Fernando") and Record World ("SOS") charts. Both "Dancing Queen" and "Take A Chance On Me" were certified gold by the Recording Industry Association of America for sales of over one million copies each.The group also had 12 Top 20 singles on the Billboard Adult Contemporary chart with two of them, "Fernando" and "The Winner Takes It All", reaching number-one. "Lay All Your Love on Me" was ABBA's fourth number-one single on a Billboard chart, topping the Hot Dance Club Play chart. Nine ABBA albums made their way into the top half of the Billboard 200 album chart, with seven of them reaching the Top 50 and four reaching the Top 20. ABBA: The Album was the highest-charting album of the group's career, peaking at No. 14. Five albums received RIAA gold certification (more than 500,000 copies sold), while three acquired platinum status (selling more than one million copies). The album, Gold - Greatest Hits, was released in the United States in 1993. It topped the Billboard Top Pop Catalog Albums chart in August 2008, being the group’s first number one album ever on any of the Billboard album charts. It sold 6x Platinum (1x Platinum = one million copies). On 15 March 2010, ABBA were inducted into the Rock and Roll Hall of Fame by Bee Gees members Barry Gibb and Robin Gibb. The ceremony was held at the Waldorf Astoria Hotel in New York City. The group was represented by Anni-Frid Lyngstad and Benny Andersson. == Members == Agnetha Fältskog – lead and backing vocals Anni-Frid "Frida" Lyngstad – lead and backing vocals Björn Ulvaeus – rhythm guitar, backing and lead vocals Benny Andersson – keyboards, synthesizers, piano, backing and lead vocals == Notable ABBA related tributes == === Musical groups === Abbaesque – An Irish ABBA tribute band A*Teens – A pop music group from Stockholm, Sweden Björn Again – The earliest-formed ABBA tribute band (1988) Gabba – An ABBA–Ramones tribute band that covers the former in the style of the latter, the name being a pun on "Gabba Gabba Hey". === Media === Saturday Night (1975) (TV) ....

### Instruction: retrieve labels for this: The MessagePad is the first series of personal digital assistant devices developed by Apple Computer for the Newton platform in 1993. Some electronic engineering and the manufacture of Apple's MessagePad devices was undertaken in Japan by the Sharp Corporation. The devices were based on the ARM 610 RISC processor and all featured handwriting recognition software and were developed and marketed by Apple. The devices ran the Newton OS. == Details == === Screen and input === With the MessagePad 120 with Newton OS 2.0, the Newton Keyboard by Apple became available, which can also be used via the dongle on Newton devices with a Newton InterConnect port, most notably the Apple MessagePad 2000/2100 series, as well as the Apple eMate 300. Newton devices featuring Newton OS 2.1 or higher can be used with the screen turned horizontally ("landscape") as well as vertically ("portrait"). A change of a setting rotates the contents of the display by 90, 180 or 270 degrees. Handwriting recognition still works properly with the display rotated, although display calibration is needed when rotation in any direction is used for the first time or when the Newton device is reset. ==== Handwriting recognition ==== In initial versions (Newton OS 1.x) the handwriting recognition gave extremely mixed results for users and was sometimes inaccurate. The original handwriting recognition engine was called Calligrapher, and was licensed from a Russian company called Paragraph International. Calligrapher's design was quite sophisticated; it attempted to learn the user's natural handwriting, using a database of known words to make guesses as to what the user was writing, and could interpret writing anywhere on the screen, whether hand-printed, in cursive, or a mix of the two. By contrast, Palm Pilot's Graffiti had a less sophisticated design than Calligrapher, but was sometimes found to be more accurate and precise due to its reliance on a fixed, predefined stroke alphabet. The stroke alphabet used letter shapes which resembled standard handwriting, but which were modified to be both simple and very easy to differentiate. Palm Computing also released two versions of Graffiti for Newton devices. Ironically, the Newton version sometimes performed better and could also show strokes as they were being written as input was done on the display itself, rather than on a silkscreen area. For editing text, Newton had a very intuitive system for handwritten editing, such as scratching out words to be deleted, circling text to be selected, or using written carets to mark inserts.Later releases of the Newton operating system retained the original recognizer for compatibility, but added a hand-printed-text-only (not cursive) recognizer, called "Rosetta", which was developed by Apple, included in version 2.0 of the Newton operating system, and refined in Newton 2.1. Rosetta is generally considered a significant improvement and many reviewers, testers, and most users consider the Newton 2.1 handwriting recognition software better than any of the alternatives even 10 years after it was introduced. Recognition and computation of handwritten horizontal and vertical formulas such as "1 + 2 =" was also under development but never released. However, users wrote similar programs which could evaluate mathematical formulas using the Newton OS Intelligent Assistant, a unique part of every Newton device. The handwriting recognition and parts of the user interface for the Newton are best understood in the context of the broad history of Pen computing, which is quite extensive.A vital feature of the Newton handwriting recognition system is the modeless error correction. That is, correction done in situ without using a separate window or widget, using a minimum of gestures. If a word is recognized improperly, the user could double-tap the word and a list of alternatives would pop up in a menu under the stylus. Most of the time, the correct word will be in the list. If not, a button at the bottom of the list allows the user to edit individual characters in that word. Other pen gestures could do such things as transpose letters (also in situ). The correction popup also allowed the user to revert to the original, un-recognized letter shapes - this would be useful in note-taking scenarios if there was insufficient time to make corrections immediately. To conserve memory and storage space, alternative recognition hypotheses would not be saved indefinitely. If the user returned to a note a week later, for example, they would only see the best match. Error correction in many current handwriting systems provides such functionality but adds more steps to the process, greatly increasing the interruption to a user's workflow that a given correction requires. ==== User interface ==== Text could also be entered by tapping with the stylus on a small on-screen pop-up QWERTY virtual keyboard, although more layouts were developed by users. Newton devices could also accept free-hand "Sketches", "Shapes", and "Ink Text", much like a desktop computer graphics tablet. With "Shapes", Newton could recognize that the user was attempting to draw a circle, a line, a polygon, etc., and it would clean them up into perfect vector representations (with modifiable control points and defined vertices) of what the user was attempting to draw. "Shapes" and "Sketches" could be scaled or deformed once drawn. "Ink text" captured the user's free-hand writing but allowed it to be treated somewhat like recognized text when manipulating for later editing purposes ("ink text" supported word wrap, could be formatted to be bold, italic, etc.). At any time a user could also direct their Newton device to recognize selected "ink text" and turn it into recognized text (deferred recognition). A Newton note (or the notes attached to each contact in Names and each Dates calendar or to-do event) could contain any mix of interleaved text, Ink Text, Shapes, and Sketches. While the Newton offered handwriting recognition training and would clean up sketches into vector shapes, both were unreliable and required much rewriting and redrawing. The most reliable application of the Newton was collecting and organizing address and phone numbers. While handwritten messages could be stored, they could not be easily filed, sorted or searched. While the technology was a probable cause for the failure of the device (which otherwise met or exceeded expectations), the technology has been instrumental in producing the future generation of handwriting software that realizes the potential and promise that began in the development of Newton-Apple's Ink Handwriting Recognition. === Connectivity === The MessagePad 100 series of devices used Macintosh's proprietary serial ports—round Mini-DIN 8 connectors. The MessagePad 2000/2100 models (as well as the eMate 300) have a small, proprietary Newton InterConnect port. However, the development of the Newton hardware/software platform was canceled by Steve Jobs on February 27, 1998, so the InterConnect port, while itself very advanced, can only be used to connect a serial dongle. A prototype multi-purpose InterConnect device containing serial, audio in, audio out, and other ports was also discovered. In addition, all Newton devices have infrared connectivity, initially only the Sharp ASK protocol, but later also IrDA, though the Sharp ASK protocol was kept in for compatibility reasons. Unlike the Palm Pilot, all Newton devices are equipped with a standard PC Card expansion slot (two on the 2000/2100). This allows native modem and even Ethernet connectivity; Newton users have also written drivers for 802.11b wireless networking cards and ATA-type flash memory cards (including the popular CompactFlash format), as well as for Bluetooth cards. Newton can also dial a phone number through the built-in speaker of the Newton device by simply holding a telephone handset up to the speaker and transmitting the appropriate tones. Fax and printing support is also built in at the operating system level, although it requires peripherals such as parallel adapters, PCMCIA cards, or serial modems, the most notable of which is the lightweight Newton Fax Modem released by Apple in 1993. It is powered by 2 AA batteries, and can also be used with a power adapter. It provides data transfer at 2400 bit/s, and can also send and receive fax messages at 9600 and 4800 bit/s respectively. === Power options === The original Apple MessagePad and MessagePad 100 used four AAA batteries. They were eventually replaced by AA batteries with the release of the Apple MessagePad 110. The use of 4 AA NiCd (MessagePad 110, 120 and 130) and 4x AA NiMH cells (MP2x00 series, eMate 300) give a runtime of up to 30 hours (MP2100 with two 20 MB Linear Flash memory PC Cards, no backlight usage) and up to 24 hours with backlight on. While adding more weight to the handheld Newton devices than AAA batteries or custom battery packs, the choice of an easily replaceable/rechargeable cell format gives the user a still unsurpassed runtime and flexibility of power supply. This, together with the flash memory used as internal storage starting with the Apple MessagePad 120 (if all cells lost their power, no data was lost due to the non-volatility of this storage), gave birth to the slogan "Newton never dies, it only gets new batteries". === Later efforts and improvements === The Apple MessagePad 2000/2100, with a vastly improved handwriting recognition system, 162 MHz StrongARM SA-110 RISC processor, Newton OS 2.1, and a better, clearer, backlit screen, attracted critical plaudits. === Cases === Apple and third parties marketed several "wallets" (cases) for the handheld Newton devices, which would hold them securely along with the owner's credit cards, driver's license, business cards, and cash. Most also protected the LCD screen. == Market reception == Fourteen months after Sculley demoed it at the May 1992, Chicago CES, the MessagePad was first offered for sale on August 2, 1993, at the Boston Macworld Expo. The hottest item at the show, it cost $900. 50,000 MessagePads were sold in the device’s first three months on the market.The original Apple MessagePad and MessagePad 100 were limited by the very short lifetime of their inadequate AAA batteries. Critics also panned the handwriting recognition that was available in the debut models, which had been trumpeted in the Newton's marketing campaign. It was this problem that was skewered in the Doonesbury comic strips in which a written text entry is (erroneously) translated as "Egg Freckles?", as well as in the animated series The Simpsons. However, the word 'freckles' was not included in the Newton dictionary, although a user could add it themselves. Difficulties were in part caused by the long time requirements for the Calligrapher handwriting recognition software to "learn" the user's handwriting; this process could take from two weeks to two months. Another factor which limited the early Newton devices' appeal was that desktop connectivity was not included in the basic retail package, a problem that was later solved with 2.x Newton devices - these were bundled with a serial cable and the appropriate Newton Connection Utilities software. Later versions of Newton OS offered improved handwriting recognition, quite possibly a leading reason for the continued popularity of the devices among Newton users. Even given the age of the hardware and software, Newtons still demand a sale price on the used market far greater than that of comparatively aged PDAs produced by other companies. In 2006 CNET compared an Apple MessagePad 2000 to a Samsung Q1, and the Newton was declared better. In 2009, CNET compared an Apple MessagePad 2000 to an iPhone, and the Newton was still declared better.A chain of dedicated Newton only stores called Newton Source existed from 1994 until 1998. Locations included New York, Los Angeles, San Francisco, Chicago and Boston. The Westwood Village, California, near U.C.L.A. featured the trademark red and yellow lightbulb Newton logo in neon. The stores provided an informative educational venue to learn about the Newton platform in a hands on relaxed fashion. The stores had no traditional computer retail counters and featured oval desktops where interested users could become intimately involved with the Newton product range. The stores were a model for the later Apple Stores. == Newton device models == Notes: The eMate 300 actually has ROM chips silk screened with 2.2 on them. Stephanie Mak on her website discusses this: If one removes all patches to the eMate 300 (by replacing the ROM chip, and then putting in the original one again, as the eMate and the MessagePad 2000/2100 devices erase their memory completely after replacing the chip), the result will be the Newton OS saying that this is version 2.2.00. Also, the Original MessagePad and the MessagePad 100 share the same model number, as they only differ in the ROM chip version. (The OMP has OS versions 1.0 to 1.05, or 1.10 to 1.11, while the MP100 has 1.3 that can be upgraded with various patches.) == Timeline of Newton models == == Other uses == There were a number of projects that used the Newton as a portable information device in cultural settings such as museums. For example, Visible Interactive created a walking tour in San Francisco's Chinatown but the most significant effort took place in Malaysia at the Petronas Discovery Center, known as Petrosains.In 1995, an exhibit design firm, DMCD Inc., was awarded the contract to design a new 100,000-square-foot (9,300 m2) science museum in the Petronas Towers in Kuala Lumpur. A major factor in the award was the concept that visitors would use a Newton device to access additional information, find out where they were in the museum, listen to audio, see animations, control robots and other media, and to bookmark information for printout at the end of the exhibit. The device became known as the ARIF, a Malay word for "wise man" or "seer" and it was also an acronym for A Resourceful Informative Friend. Some 400 ARIFS were installed and over 300 are still in use today. The development of the ARIF system was extremely complex and required a team of hardware and software engineers, designers, and writers. ARIF is an ancestor of the PDA systems used in museums today and it boasted features that have not been attempted since. The Newton was also used in healthcare applications, for example in collecting data directly from patients. Newtons were used as electronic diaries, with patients entering their symptoms and other information concerning their health status on a daily basis. The compact size of the device and its ease of use made it possible for the electronic diaries to be carried around and used in the patients' everyday life setting. This was an early example of electronic patient-reported outcomes (ePRO) == See also == Newton (platform) Newton OS eMate 300 NewtonScript Orphaned technology Pen computing == References == == Bibliography == Apple's press release on the debut of the MessagePad 2100 Apple's overview of features & limitations of Newton Connection Utilities Newton overview at Newton Source archived from Apple Newton FAQ Pen Computing's First Look at Newton OS 2.0 Newton Gallery Birth of the Newton The Newton Hall of Fame: People behind the Newton Pen Computing's Why did Apple kill the Newton?

### Instruction: retrieve labels for this: Alfred Elton van Vogt (; April 26, 1912 – January 26, 2000) was a Canadian-born science fiction author. He is regarded as one of the most popular, influential and complex practitioners of the mid-twentieth century, the genre's so-called Golden Age. == Biography == === Early life and writings === Alfred Vogt (both "Elton" and "van" were added much later) was born on April 26, 1912 on his grandparents' farm in Edenburg, Manitoba, a tiny (and now defunct) Russian Mennonite community east of Gretna, Manitoba, Canada. He was the third of six children born to Heinrich "Henry" Vogt and Aganetha "Agnes" Vogt (née Buhr), both of whom were themselves born in Manitoba, but who grew up in heavily immigrant communities. Until age four, van Vogt and his family spoke only a dialect of Low German at home.For the first dozen or so years of his life, van Vogt's father, a lawyer, moved his family several times within western Canada, alighting successively in Neville, Saskatchewan; Morden, Manitoba; and finally Winnipeg, Manitoba. His son found these moves difficult, later remarking: Childhood was a terrible period for me. I was like a ship without anchor being swept along through darkness in a storm. Again and again I sought shelter, only to be forced out of it by something new. By the 1920s, living in Winnipeg, father Henry worked as an agent for a steamship company, but the stock market crash of 1929 proved financially disastrous, as the family was unable to afford to send Alfred to college. During his teen years, Alfred worked as a farmhand and a truck driver, and by the age of 19, he was working in Ottawa for the Canadian census bureau. He began his writing career with stories in the true confession style of pulp magazines such as True Story. Most of these stories were published anonymously, with the first-person narratives allegedly being written by people (often women) in extraordinary, emotional, and life-changing circumstances. After a year in Ottawa, he moved back to Winnipeg, where he sold newspaper advertising space and continued to write. While continuing to pen melodramatic "true confessions" stories through 1937, he also began writing short radio dramas for local radio station CKY, as well as conducting interviews published in trade magazines. He added the middle name "Elton" at some point in the mid-1930s, and at least one confessional story (1937's "To Be His Keeper") was sold to the Toronto Star, who misspelled his name "Alfred Alton Bogt" in the byline. Shortly thereafter, he added the "van" to his surname, and from that point forward he used the name "A.E. van Vogt" both personally and professionally. === Early science fiction career (1939-1944) === By 1938, van Vogt decided to switch to writing science fiction, a genre he enjoyed reading. He was inspired by the August 1938 issue of Astounding Science Fiction, which he picked up at a newsstand. John W. Campbell's novelette "Who Goes There?" (later adapted into The Thing from Another World and The Thing) inspired van Vogt to write "Vault of the Beast", which he submitted to that same magazine. Campbell, who edited Astounding (and had written the story under a pseudonym), sent van Vogt a rejection letter, but one which encouraged van Vogt to try again. Van Vogt sent another story, entitled "Black Destroyer," which was accepted. A revised version of "Vault of the Beast" would be published in 1940. Van Vogt's first SF publication was inspired by The Voyage of the Beagle by Charles Darwin. "The Black Destroyer" was published in July 1939 by John W. Campbell in Astounding Science Fiction, the centennial year of Darwin's journal. It featured a fierce, carnivorous alien, the coeurl, stalking the crew of an exploration spaceship, and served as the inspiration for multiple science fiction movies, including Alien (1979).Also in 1939, still living in Winnipeg, van Vogt married Edna Mayne Hull, a fellow Manitoban. Hull, who had previously worked as an private secretary, would act as van Vogt's typist, and be credited with writing several SF stories of her own throughout the early 1940s. The outbreak of World War II in September 1939 caused a change in van Vogt's circumstances. Ineligible for military service due to his poor eyesight, van Vogt accepted a clerking job with the Canadian Department of National Defence. This necessitated a move back to Ottawa, where he and his wife would stay for the next year-and-a-half. Meanwhile, his writing career continued. "Discord in Scarlet" was van Vogt's second story to be published, also appearing as the cover story. It was accompanied by interior illustrations created by Frank Kramer and Paul Orban. (Van Vogt and Kramer thus debuted in the issue of Astounding that is sometimes identified as the start of the Golden Age of Science Fiction.) Van Vogt's first completed novel, and one of his most famous, is Slan (Arkham House, 1946), which Campbell serialized in Astounding September to December 1940. Using what became one of van Vogt's recurring themes, it told the story of a 9-year-old superman living in a world in which his kind are slain by Homo sapiens. Others saw van Vogt's talent and stardom from his first story, and in May 1941, van Vogt decided to become a full-time writer, quitting his job at the Canadian Department of National Defence. Freed from the necessity of living in Ottawa, he and his wife lived for a time in the Gatineau region of Quebec before moving to Toronto in the fall of 1941. Prolific throughout this period, van Vogt wrote many of his more famous short stories and novels in the years from 1941 through 1944. The novels The Book of Ptath and The Weapon Makers both appeared in magazines in serial form during this era; they were later published in book form after World War II. As well, several (though not all) of the stories that were compiled to make up the novels The Weapon Shops of Isher, The Mixed Men and The War Against the Rull were also published during this time. === Move to California life and post-war writing (1944-1950) === In November 1944, van Vogt and Hull moved to Hollywood; van Vogt would spend the rest of his life in California. He had been using the name "A.E. van Vogt" in his public life for several years, and as part of the process of obtaining American citizenship in 1945 he finally and formally changed his legal name from Alfred Vogt to Alfred Elton van Vogt. To his friends in the California science fiction community, he was known as "Van". Van Vogt systematized his writing method, using scenes of 800 words or so where a new complication was added or something resolved. Several of his stories hinge on temporal conundra, a favorite theme. He stated that he acquired many of his writing techniques from three books: Narrative Technique by Thomas Uzzell, The Only Two Ways to Write a Story by John Gallishaw, and Twenty Problems of the Fiction Writer by Gallishaw. He also claimed many of his ideas came from dreams; throughout his writing life he arranged to be awakened every 90 minutes during his sleep period so he could write down his dreams.Van Vogt was also always interested in the idea of all-encompassing systems of knowledge (akin to modern meta-systems) — the characters in his very first story used a system called "Nexialism" to analyze the alien's behavior. Around this time, he became particularly interested in the general semantics of Alfred Korzybski. He subsequently wrote a novel merging these overarching themes, The World of Ā, originally serialized in Astounding in 1945. Ā (often rendered as Null-A), or non-Aristotelian logic, refers to the capacity for, and practice of, using intuitive, inductive reasoning (compare fuzzy logic), rather than reflexive, or conditioned, deductive reasoning. The novel recounts the adventures of an individual living in an apparent Utopia, where those with superior brainpower make up the ruling class ... though all is not as it seems. A sequel, The Players of Ā (later re-titled The Pawns of Null-A) was serialized in 1948/49. At the same time, in his fiction, van Vogt was consistently sympathetic to absolute monarchy as a form of government. This was the case, for instance, in the Weapon Shop series, the Mixed Men series, and in single stories such as "Heir Apparent" (1945), whose protagonist was described as a "benevolent dictator". These sympathies were the subject of much critical discussion during van Vogt's career, and afterwards. Van Vogt published "Enchanted Village" in the July 1950 issue of Other Worlds Science Stories. It was reprinted in over 20 collections or anthologies, and appeared many times in translation. === Dianetics and fix-ups (1950-1961) === In 1950, van Vogt was briefly appointed as head of L. Ron Hubbard's Dianetics operation in California. Van Vogt had first met Hubbard in 1945, and became interested in his Dianetics theories, which were published shortly thereafter. Dianetics was the secular precursor to Hubbard's Church of Scientology; van Vogt would have no association with Scientology, as he did not approve of its mysticism. The California Dianetics operation went broke nine months later, but never went bankrupt, due to van Vogt's arrangements with creditors. Very shortly after that, van Vogt and his wife opened their own Dianetics center, partly financed by his writings, until he "signed off" around 1961. In practical terms, what this meant was that from 1951 through 1961, van Vogt's focus was on Dianetics, and no new story ideas flowed from his typewriter. However, during the 1950s, van Vogt retrospectively patched together many of his previously published stories into novels, sometimes creating new interstitial material to help bridge gaps in the narrative. Van Vogt referred to the resulting books as "fix-ups", a term that entered the vocabulary of science-fiction criticism. When the original stories were closely related this was often successful -- although some van Vogt fix-ups featured disparate stories thrown together that bore little relation to each other, generally making for a less coherent plot. One of his most well-known (and well-regarded) novels, The Voyage of the Space Beagle (1950) was a fix-up of four short stories including "Discord in Scarlet"; it was published in at least five European languages by 1955.Still, although Van Vogt averaged a new book title every ten months from 1951 to 1961, none of them were new stories. All of van Vogt's books from 1951-1961 are fix-ups, collections of previously published stories, expansions of previously published short stories to novel length, or republications of his books under new titles. All were based on story material written and originally published between 1939 and 1950. As well, one non-fiction work, The Hypnotism Handbook, appeared in 1956, though it had apparently been written much earlier. Some of van Vogt's more well-known work was still produced using the fix-up method. In 1951, he published the fix-up The Weapon Shops of Isher. In the same decade, van Vogt also produced collections and fixups such as The Mixed Men (1952), The War Against the Rull (1959), and the two "Clane" novels, Empire of the Atom (1957) and The Wizard of Linn (1962), which were inspired (like Asimov's Foundation series) by Roman imperial history, specifically the reign of Claudius. After more than a decade of running their Dianetics center, Hull and van Vogt closed it in 1961. Nevertheless, van Vogt maintained his association with the overall organization and was still president of the Californian Association of Dianetic Auditors into the 1980s. === Return to writing and later career (1962-1986) === Though the constant re-packaging of his older work meant that he had never really been away from the book publishing world, van Vogt had not published any wholly new fiction for almost 12 years when he decided to return to writing in 1962. He did not return immediately to science fiction, however, but instead wrote the only mainstream, non-sf novel of his career. Van Vogt was profoundly affected by revelations of totalitarian police states that emerged after World War II. Accordingly, he wrote a mainstream novel that he set in Communist China, The Violent Man (1962); he said that to research this book he had read 100 books about China. Into this book he incorporated his view of "the violent male type", which he described as a "man who had to be right", a man who "instantly attracts women" and who he said were the men who "run the world". Contemporary reviews were lukewarm at best, and van Vogt thereafter returned to science fiction. From 1963 through the mid-1980s, van Vogt once again published new material on a regular basis, though fix-ups and reworked material also appeared relatively often. His later novels included fixups such as The Beast (also known as Moonbeast) (1963), Rogue Ship (1965), Quest for the Future (1970) and Supermind (1977). He also wrote novels by expanding previously published short stories; works of this type include The Darkness on Diamondia (1972) and Future Glitter (also known as Tyranopolis; 1973). Novels that were written simply as novels, and not serialized magazine pieces or fix-ups, were very rare in van Vogt's oeuvre, but began to appear regularly beginning in the 1970s. Van Vogt's original novels included Children of Tomorrow (1970), The Battle of Forever (1971) and The Anarchistic Colossus (1977). Over the years, many sequels to his classic works were promised, but only one appeared: Null-A Three (1984; originally published in French). Several later books were originally published in Europe, and at least one novel only ever appeared in foreign language editions and was never published in its original English. Van Vogt's first wife, Edna Mayne Hull, died in 1975. Van Vogt would marry Lydia Bereginsky in 1979; they remained together until his death. === Final years === When the 1979 film Alien appeared, it was noted that the plot closely matched the plot of van Vogt's Voyage of the Space Beagle. Van Vogt sued the production company for plagiarism, and eventually collected an out-of-court settlement of $50,000 from 20th Century Fox.In increasingly frail health, van Vogt's final short story appeared in 1986. The Science Fiction Writers of America named him its 14th Grand Master in 1995 (presented 1996). Also in 1996, van Vogt received a Special Award from the World Science Fiction Convention "for six decades of golden age science fiction". That same year, he was inducted as an inaugural member of the Science Fiction and Fantasy Hall of Fame.On January 26, 2000, A.E. van Vogt died in Los Angeles from Alzheimer's disease. He was survived by his second wife, the former Lydia Bereginsky. == Critical reception == Critical opinion about the quality of van Vogt's work is sharply divided. An early and articulate critic was Damon Knight. In a 1945 chapter-long essay reprinted in In Search of Wonder, entitled "Cosmic Jerrybuilder: A. E. van Vogt", Knight described van Vogt as "no giant; he is a pygmy who has learned to operate an overgrown typewriter". Knight described The World of Null-A as "one of the worst allegedly adult science fiction stories ever published". Concerning van Vogt's writing, Knight said: In general van Vogt seems to me to fail consistently as a writer in these elementary ways: 1. His plots do not bear examination. 2. His choice of words and his sentence-structure are fumbling and insensitive. 3. He is unable either to visualize a scene or to make a character seem real. About Empire of the Atom Knight wrote: If you can only throw your reasoning powers out of gear — something many van Vogt fans find easy to do — you'll enjoy this one. Knight also expressed misgivings about van Vogt's politics. He noted that van Vogt's stories almost invariably present absolute monarchy in a favorable light. In 1974, Knight retraced some of his criticism after finding out about Vogt's working methods about writing down his dreams: This explains a good deal about the stories, and suggests that it is really useless to attack them by conventional standards. If the stories have a dream consistency which affects readers powerfully, it is probably irrelevant that they lack ordinary consistency. Knight's criticism greatly damaged van Vogt's reputation. On the other hand, when science fiction author Philip K. Dick was asked which science fiction writers had influenced his work the most, he replied: I started reading sf when I was about twelve and I read all I could, so any author who was writing about that time, I read. But there's no doubt who got me off originally and that was A.E. van Vogt. There was in van Vogt's writing a mysterious quality, and this was especially true in The World of Null A [sic]. All the parts of that book did not add up; all the ingredients did not make a coherency. Now some people are put off by that. They think that's sloppy and wrong, but the thing that fascinated me so much was that this resembled reality more than anybody else's writing inside or outside science fiction. Dick also defended van Vogt against Damon Knight’s criticisms: Damon feels that it's bad artistry when you build those funky universes where people fall through the floor. It's like he's viewing a story the way a building inspector would when he's building your house. But reality really is a mess, and yet it's exciting. The basic thing is, how frightened are you of chaos? And how happy are you with order? Van Vogt influenced me so much because he made me appreciate a mysterious chaotic quality in the universe which is not to be feared. In a review of Transfinite: The Essential A.E. van Vogt, science fiction writer Paul Di Filippo said: Van Vogt knew precisely what he was doing in all areas of his fiction writing. There's hardly a wasted word in his stories. [...] His plots are marvels of interlocking pieces, often ending in real surprises and shocks, genuine paradigm shifts, which are among the hardest conceptions to depict. And the intellectual material of his fictions, the conceits and tossed-off observations on culture and human and alien behavior, reflect a probing mind. [...] Each tale contains a new angle, a unique slant, that makes it stand out. In The John W. Campbell Letters, Campbell says, "The son-of-a-gun gets hold of you in the first paragraph, ties a knot around you, and keeps it tied in every paragraph thereafter—including the ultimate last one".Harlan Ellison (who had begun reading van Vogt as a teenager) wrote, "Van was the first writer to shine light on the restricted ways in which I had been taught to view the universe and the human condition".Writing in 1984, David Hartwell said: No one has taken van Vogt seriously as a writer for a long time. Yet he has been read and still is. What no one seems to have noticed is that van Vogt, more than any other single SF writer, is the conduit through which the energy of Gernsbackian, primitive wonder stories have been transmitted through the Campbellian age, when earlier styles of SF were otherwise rejected, and on into SF of the present. The literary critic Leslie A. Fiedler said something similar: Van Vogt is a test case [...] since an apology for or analysis of science fiction which fails to come to terms with his appeal and major importance, defends or defines the genre by falsifying it. American literary critic Fredric Jameson says of van Vogt: that van Vogt's work clearly prepares the way for that of the greatest of all Science Fiction writers, Philip K. Dick, whose extraordinary novels and stories are inconceivable without the opening onto that play of unconscious materials and fantasy dynamics released by van Vogt, and very different from the more hard-science aesthetic ideologies of his contemporaries (from Campbell to Heinlein). Van Vogt still has his critics. For example, Darrell Schweitzer writing to The New York Review of Science Fiction in 1999 quoted a passage from the original van Vogt novelette "The Mixed Men", which he was then reading, and remarked: This is the realism, and logic, of a small boy playing with toy soldiers in a sandbox. I'm tougher than you. I’ve got a billion spaceships! They’re brand-new. They only took 800 years to develop. And this is a story in which most of the cast either have two brains or are really robots [...] and even the emotions of the human characters are programmed or deprogrammed as part of plots within counter plots. Next to this, Doc Smith was an icy realist. There is no intersection with adult reality at any point, for all van Vogt was able to write was that small boy's sandbox game with an adult level of intensity. This is, I think, the secret of van Vogt's bizarre fascination, as awful as his actual writing might be, and why he appealed so strongly to Philip K. Dick, who managed to put more adult characters and emotions into equally crazy situations. It's ultimately very strange to find this sort of writing so prominently sponsored by supposedly rational and scientifically minded John W. Campbell, when it seems to contravene everything the Golden Age stood for. == Recognition == In 1946, van Vogt and his first wife, Edna Mayne Hull, were Guests of Honor at the fourth World Science Fiction Convention.In 1980, van Vogt received a "Casper Award" (precursor to the Canadian Prix Aurora Awards) for Lifetime Achievement.The Science Fiction Writers of America named him its 14th Grand Master in 1995 (presented 1996). Great controversy within SFWA accompanied its long wait in bestowing its highest honor (limited to living writers, no more than one annually). Writing an obituary of van Vogt, Robert J. Sawyer, a fellow Canadian writer of science fiction, remarked: There was no doubt that van Vogt should have received this honor much earlier — the injustice of him being overlooked, at least in part because of damnable SFWA politics, had so incensed Harlan Ellison, a man with an impeccable moral compass, that he'd lobbied hard on the Sci-Fi Channel and elsewhere on van Vogt's behalf. It is generally held that the "damnable SFWA politics" concerns Damon Knight, the founder of the SFWA, who abhorred van Vogt's style and politics and thoroughly demolished his literary reputation in the 1950s.Harlan Ellison was more explicit in 1999 introduction to Futures Past: The Best Short Fiction of A. E. van Vogt: [A]t least I was able to make enough noise to get Van the Science Fiction Writers of America Grand Master Award, which was presented to him in full ceremony during one of the last moments when he was cogent and clearheaded enough to understand that finally, at last, dragged kicking and screaming to honor him, the generation that learned from what he did and what he had created had, at last, 'fessed up to his importance. .[]..] were the same ones who assured me that Van would never get the Grand Master until Damon Knight had gotten it first, because Damon had loathed Van's work and had, in fact written the essay that ridiculed Van and held him up to opprobrium for decades thereafter, and Damon having founded SFWA it would be an affront to him if Van got it first. Well, I don't know if that's true or not, though it was common coin in the field for years; but Damon got the Grand Master award in 1994. And Van got it in 1995. As they say during sweeps week on television: coincidence or conspiracy? In 1996, van Vogt received a Special Award from the World Science Fiction Convention "for six decades of golden age science fiction".

### Instruction: retrieve labels for this: Anna Sergeyevna Kournikova (Russian: А́нна Серге́евна Ку́рникова, IPA: [ˈannə sʲɪrˈɡʲejɪvnə ˈkurnʲɪkəvə] ( listen); born 7 June 1981) is a Russian former professional tennis player. Her appearance and celebrity status made her one of the best known tennis stars worldwide. At the peak of her fame, fans looking for images of Kournikova made her name one of the most common search strings on Google Search.Despite never winning a singles title, she reached No. 8 in the world in 2000. She achieved greater success playing doubles, where she was at times the world No. 1 player. With Martina Hingis as her partner, she won Grand Slam titles in Australia in 1999 and 2002, and the WTA Championships in 1999 and 2000. They referred to themselves as the "Spice Girls of Tennis".Kournikova retired at the age of 21 due to serious back and spinal problems, including a herniated disk. She lives in Miami Beach, Florida, and plays in occasional exhibitions and in doubles for the St. Louis Aces of World Team Tennis. She was a new trainer for season 12 of the television show The Biggest Loser, replacing Jillian Michaels, but did not return for season 13. In addition to her tennis and television work, Kournikova serves as a Global Ambassador for Population Services International's "Five & Alive" program, which addresses health crises facing children under the age of five and their families. == Early life == Anna Kournikovas father, Sergei Kournikov (born 1961), a former Greco-Roman wrestling champion, eventually earned a PhD and was a professor at the University of Physical Culture and Sport in Moscow. As of 2001, he was still a part-time martial arts instructor there. Her mother Alla (born 1963) had been a 400-metre runner. Her younger brother, Allan, is a youth golf world champion who was featured in the 2013 documentary film The Short Game.Sergei Kournikov has said, "We were young and we liked the clean, physical life, so Anna was in a good environment for sport from the beginning".Kournikova received her first tennis racquet as a New Year gift in 1986 at age five. Describing her early regimen, she said, "I played two times a week from age six. It was a children's program. And it was just for fun; my parents didn't know I was going to play professionally, they just wanted me to do something because I had lots of energy. It was only when I started playing well at seven that I went to a professional academy. I would go to school, and then my parents would take me to the club, and I'd spend the rest of the day there just having fun with the kids." In 1986, Kournikova became a member of the Spartak Tennis Club, coached by Larissa Preobrazhenskaya. In 1989, at the age of eight, Kournikova began appearing in junior tournaments, and by the following year, was attracting attention from tennis scouts across the world. She signed a management deal at age ten and went to Bradenton, Florida, to train at Nick Bollettieri's celebrated tennis academy. == Tennis career == === 1989–1997: Early years and breakthrough === Following her arrival in the United States, she became prominent on the tennis scene. At 14, she won the European Championships and the Italian Open Junior tournament. She became the youngest player to win the 18-and-under division of the Junior Orange Bowl tennis tournament.

She debuted in professional tennis at 14 in the Fed Cup for Russia, the youngest player ever to participate and win. In 1995, she turned pro, and won two ITF titles, in Midland, Michigan and Rockford, Illinois. The same year Kournikova reached her first WTA Tour doubles final at the Kremlin Cup. Partnering with 1995 Wimbledon girls' champion in both singles and doubles, Aleksandra Olsza, she lost to Meredith McGrath and Larisa Neiland. In 1996, she started playing under a new coach, Ed Nagel. Her six-year tenure with Ed would produce terrific results. At 15, she made her Grand Slam debut, when she reached the fourth round of the 1996 US Open, only to be stopped by then-top ranked player Steffi Graf, the eventual champion. After this tournament, Kournikova's ranking jumped from No. 144 to debut in the Top 100 at No. 69. Kournikova was a member of the Russian delegation to the 1996 Olympic Games in Atlanta, Georgia. In 1996, she was named WTA Newcomer of the Year, and she was ranked No. 57 in the end of the season.Kournikova entered the 1997 Australian Open as world No. 67, where she lost in the first round to world No. 12, Amanda Coetzer. At the Italian Open, Kournikova lost to Amanda Coetzer in the second round. However, she reached the semifinals in the doubles partnering with Elena Likhovtseva, before losing to the sixth seeds Mary Joe Fernández and Patricia Tarabini.At the French Open, Kournikova made it to the third round before losing to world No. 1, Martina Hingis. She also reached the third round in doubles with Likhovtseva.

At the US Open, she lost in the second round to the eleventh seed Irina Spîrlea. Partnering with Likhovtseva, she reached the third round of the women's doubles event. Kournikova played her last WTA Tour event of 1997 at Porsche Tennis Grand Prix in Filderstadt, losing to Amanda Coetzer in the second round of singles, and in the first round of doubles to Lindsay Davenport and Jana Novotná partnering with Likhovtseva. She broke into the top 50 on 19 May, and was ranked No. 32 in singles and No. 41 in doubles at the end of the season. === 1998–2000: Success and stardom === In 1998, Kournikova broke into the WTA's top 20 rankings for the first time, when she was ranked No. 16. At the Australian Open, Kournikova lost in the third round to world No. 1 player, Martina Hingis. She also partnered with Larisa Neiland in women's doubles, and they lost to eventual champions Hingis and Mirjana Lučić in the second round.

During her quarterfinals match at the grass-court Eastbourne Open versus Steffi Graf, Kournikova injured her thumb, which would eventually force her to withdraw from the 1998 Wimbledon Championships. However, she won that match, but then withdrew from her semifinals match against Arantxa Sánchez Vicario. Kournikova returned for the Du Maurier Open and made it to the third round, before losing to Conchita Martínez. At the US Open Kournikova reached the fourth round before losing to Arantxa Sánchez Vicario. Her strong year qualified her for the year-end 1998 WTA Tour Championships, but she lost to Monica Seles in the first round. However, with Seles, she won her first WTA doubles title, in Tokyo, beating Mary Joe Fernández and Arantxa Sánchez Vicario in the final. At the end of the season, she was ranked No. 10 in doubles.At the start of the 1999 season, Kournikova advanced to the fourth round in singles before losing to Mary Pierce. However, Kournikova won her first doubles Grand Slam title, partnering Martina Hingis. The two defeated Lindsay Davenport and Natasha Zvereva in the final.

Kournikova again qualified for year-end WTA Tour Championships, but lost to Mary Pierce in the first round, and ended the season as World No. 12. While Kournikova had a successful singles season, she was even more successful in doubles. After their victory at the Australian Open, she and Martina Hingis won tournaments in Indian Wells, Rome, Eastbourne and the WTA Tour Championshiops, and reached the final of The French Open where they lost to Serena and Venus Williams. Partnering with Elena Likhovtseva, Kournikova also reached the final in Stanford. On 22 November 1999 she reached the world No. 1 ranking in doubles, and ended the season at this ranking. Anna Kournikova and Martina Hingis were presented with the WTA Award for Doubles Team of the Year. Kournikova opened her 2000 season winning the Gold Coast Open doubles tournament partnering with Julie Halard. She then reached the singles semifinals at the Medibank International Sydney, losing to Lindsay Davenport. At the Australian Open, she reached the fourth round in singles and the semi-finals in doubles. That season, Kournikova reached eight semifinals (Sydney, Scottsdale, Stanford, San Diego, Luxembourg, Leipzig and Tour Championships), seven quarterfinals (Gold Coast, Tokyo, Amelia Island, Hamburg, Eastbourne, Zürich and Philadelphia) and one final. On 20 November 2000 she broke into top 10 for the first time, reaching No. 8. She was also ranked No. 4 in doubles at the end of the season. Kournikova was once again, more successful in doubles.

She also won six doubles titles – Gold Coast (with Julie Halard), Hamburg (with Natasha Zvereva), Filderstadt, Zürich, Philadelphia and the Tour Championships (with Martina Hingis). === 2001–2003: Injuries and final years === Her 2001 season was dominated by injury, including a left foot stress fracture which forced her withdrawal from twelve tournaments, including the French Open and Wimbledon. She underwent surgery in April. She reached her second career grand slam quarterfinals, at the Australian Open. Kournikova then withdrew from several events due to continuing problems with her left foot and did not return until Leipzig. With Barbara Schett, she won the doubles title in Sydney. She then lost in the finals in Tokyo, partnering with Iroda Tulyaganova, and at San Diego, partnering with Martina Hingis. Hingis and Kournikova also won the Kremlin Cup. At the end of the 2001 season, she was ranked No. 74 in singles and No. 26 in doubles. Kournikova was quite successful in 2002.

At the end of 2002 season, she was ranked No. 35 in singles and No. 11 in doubles.In 2003, Anna Kournikova collected her first Grand Slam match victory in two years at the Australian Open. She defeated Henrieta Nagyová in the 1st round, and then lost to Justine Henin-Hardenne in the 2nd round. She withdrew from Tokyo due to a sprained back suffered at the Australian Open and did not return to Tour until Miami. On 9 April, in what would be the final WTA match of her career, Kournikova retired in the 1st round of the Family Circle Cup in Charleston, due to a left adductor strain. Her singles world ranking was 67. She reached the semifinals at the ITF tournament in Sea Island, before withdrawing from a match versus Maria Sharapova due to the adductor injury. She lost in the 1st round of the ITF tournament in Charlottesville. She did not compete for the rest of the season due to a continuing back injury. At the end of the 2003 season and her professional career, she was ranked No. 305 in singles and No. 176 in doubles.Kournikova's two Grand Slam doubles titles came in 1999 and 2002, both at the Australian Open in the Women's Doubles event with partner Martina Hingis. Kournikova proved a successful doubles player on the professional circuit, winning 16 tournament doubles titles, including two Australian Opens and being a finalist in mixed doubles at the US Open and at Wimbledon, and reaching the No. 1 ranking in doubles in the WTA Tour rankings. Her pro career doubles record was 200–71. However, her singles career plateaued after 1999. For the most part, she managed to retain her ranking between 10 and 15 (her career high singles ranking was No.8), but her expected finals breakthrough failed to occur; she only reached four finals out of 130 singles tournaments, never in a Grand Slam event, and never won one. Her singles record is 209–129. Her final playing years were marred by a string of injuries, especially back injuries, which caused her ranking to erode gradually. As a personality Kournikova was among the most common search strings for both articles and images in her prime. === 2004–present: Exhibitions and World Team Tennis === Kournikova has not played on the WTA Tour since 2003, but still plays exhibition matches for charitable causes. In late 2004, she participated in three events organized by Elton John and by fellow tennis players Serena Williams and Andy Roddick. In January 2005, she played in a doubles charity event for the Indian Ocean tsunami with John McEnroe, Andy Roddick, and Chris Evert. In November 2005, she teamed up with Martina Hingis, playing against Lisa Raymond and Samantha Stosur in the WTT finals for charity. Kournikova is also a member of the St. Louis Aces in the World Team Tennis (WTT), playing doubles only. In September 2008, Kournikova showed up for the 2008 Nautica Malibu Triathlon held at Zuma Beach in Malibu, California. The Race raised funds for children's Hospital Los Angeles. She won that race for women's K-Swiss team. On 27 September 2008, Kournikova played exhibition mixed doubles matches in Charlotte, North Carolina, partnering with Tim Wilkison and Karel Nováček. Kournikova and Wilkison defeated Jimmy Arias and Chanda Rubin, and then Kournikova and Novacek defeated Rubin and Wilkison.On 12 October 2008, Anna Kournikova played one exhibition match for the annual charity event, hosted by Billie Jean King and Elton John, and raised more than $400,000 for the Elton John AIDS Foundation and Atlanta AIDS Partnership Fund. She played doubles with Andy Roddick (they were coached by David Chang) versus Martina Navratilova and Jesse Levine (coached by Billie Jean King); Kournikova and Roddick won.Kournikova competed alongside John McEnroe, Tracy Austin and Jim Courier at the "Legendary Night", which was held on 2 May 2009, at the Turning Stone Event Center in Verona, New York. The exhibition included a mixed doubles match of McEnroe and Austin against Courier and Kournikova. In 2008, she was named a spokesperson for K-Swiss. In 2005, Kournikova stated that if she were 100% fit, she would like to come back and compete again.In June 2010, Kournikova reunited with her doubles partner Martina Hingis to participate in competitive tennis for the first time in seven years in the Invitational Ladies Doubles event at Wimbledon. On 29 June 2010 they defeated the British pair Samantha Smith and Anne Hobbs. == Playing style == Kournikova plays right-handed with a two-handed backhand. She is a great player at the net. She can hit forceful groundstrokes and also drop shots.Her playing style fits the profile for a doubles player, and is complemented by her height. She has been compared to such doubles specialists as Pam Shriver and Peter Fleming. == Personal life == Kournikova was in a relationship with fellow Russian Pavel Bure, an NHL ice hockey player. The two met in 1999 when Kournikova was still linked to Bure's former Russian teammate Sergei Fedorov. Bure and Kournikova were reported to have been engaged in 2000 after a reporter took a photo of them together in a Florida restaurant where Bure supposedly asked Kournikova to marry him. As the story made headlines in Russia, where they were both heavily followed in the media as celebrities, Bure and Kournikova both denied any engagement. Kournikova, 10 years younger than Bure, was 18 years old at the time.Fedorov claimed he and Kournikova were married in 2001, and divorced in 2003. Kournikova's representatives deny any marriage to Fedorov; however, Fedorov's agent Pat Brisson claims that although he does not know when they got married, he knew "Fedorov was married".Kournikova started dating pop star Enrique Iglesias in late 2001 (she appeared in his video, "Escape"). She has consistently refused to directly confirm or deny the status of her personal relationships. In June 2008, Iglesias was quoted by the Daily Star as having married Kournikova the previous year and subsequently separated. The couple have invested in a $20 million home to be built on a private island in Miami. They welcomed twins, Nicholas and Lucy, on Saturday, 16 December 2017, at South Miami Hospital. == Media publicity == Most of Kournikova's fame has come from the publicity surrounding her looks and her personal life. During her debut at the 1996 US Open at the age of 15, the western world noticed her beauty, and soon pictures of her appeared in numerous magazines worldwide. In 2000, Kournikova became the new face for Berlei's shock absorber sports bras, and appeared in the "only the ball should bounce" billboard campaign. Following that, she was cast by the Farrelly brothers for a minor role in the 2000 film Me, Myself & Irene starring Jim Carrey and Renée Zellweger. Photographs of her have appeared on covers of various publications, including men's magazines, such as one in the much-publicized 2004 Sports Illustrated Swimsuit Issue, where she posed in bikinis and swimsuits, as well as in FHM and Maxim. Kournikova was named one of People's 50 Most Beautiful People in 1998 and was voted "hottest female athlete" on ESPN.com. In 2002 she also placed first in FHM's 100 Sexiest Women in the World in US and UK editions. By contrast, ESPN – citing the degree of hype as compared to actual accomplishments as a singles player – ranked Kournikova 18th in its "25 Biggest Sports Flops of the Past 25 Years". Kournikova was also ranked No. 1 in the ESPN Classic series "Who's number 1?" when the series featured sport's most overrated athletes.She continued to be the most searched athlete on the Internet through 2008 even though she had retired from the professional tennis circuit years earlier. After slipping from first to sixth among athletes in 2009, she moved back up to third place among athletes in terms of search popularity in 2010.In October 2010, Kournikova headed to NBC's The Biggest Loser where she led the contestants in a tennis-workout challenge. In May 2011, it was announced that Kournikova would join The Biggest Loser as a regular celebrity trainer in season 12. She did not return for season 13.In November 2010, she became an American citizen. In 2011, Men's Health named her one of the "100 Hottest Women of All-Time", ranking her at No. 29. == Influences on popular culture == A variation of a White Russian made with skim milk is known as an Anna Kournikova. A video game featuring Kournikova's licensed appearance, titled Anna Kournikova's Smash Court Tennis, was developed by Namco and released for the PlayStation in Japan and Europe in November 1998. A computer virus named after her arose on 12 February 2001 and infected computers worldwide through internet mail. The Texas hold 'em opening hand of Ace-King off suit is sometimes referred to as an Anna Kournikova- both for the initials on the cards and because the hand supposedly looks good, but does not win much. == Career statistics and awards == 1996: WTA Newcomer of the Year 1999: WTA Doubles Team of the Year (with Martina Hingis) == Books == Anna Kournikova by Susan Holden (2001) (ISBN 978-1-84222-416-8 / ISBN 978-1-84222-416-8) Anna Kournikova (Women Who Win) by Connie Berman (2001) (ISBN 978-0-7910-6529-7 / ISBN 978-0-7910-6529-7) == References == == External links == Official website Anna Kournikova at the Women's Tennis Association Anna Kournikova at the International Tennis Federation Anna Kournikova at the Fed Cup Anna Kournikova on IMDb ### Answer: <1981 births>, <Australian Open (tennis) champions>, <Grand Slam (tennis) champions in women\'s doubles>, <Living people>, <Olympic tennis players of Russia>, <Participants in American reality television series>, <Russian emigrants to the United States>, <Russian female models>, <Russian female tennis players>, <Russian socialites>, <Sportspeople from Miami-Dade County, Florida>, <Sportspeople from Moscow>, <Tennis players at the 1996 Summer Olympics>

### Instruction: retrieve labels for this: Alfons Maria Jakob (2 July 1884 in Aschaffenburg/Bavaria – 17 October 1931 in Hamburg) was a German neurologist who worked in the field of neuropathology. He was born in Aschaffenburg, Bavaria and educated in medicine at the universities of Munich, Berlin, and Strasbourg, where he received his doctorate in 1908. During the following year, he began clinical work under the psychiatrist Emil Kraepelin and did laboratory work with Franz Nissl and Alois Alzheimer in Munich.In 1911, by way of an invitation from Wilhelm Weygandt, he relocated to Hamburg, where he worked with Theodor Kaes and eventually became head of the laboratory of anatomical pathology at the psychiatric State Hospital Hamburg-Friedrichsberg. Following the death of Kaes in 1913, Jakob succeeded him as prosector. During World War I he served as an army physician in Belgium, and afterwards returned to Hamburg. In 1919 he obtained his habilitation for neurology and in 1924 became a professor of neurology. Under Jakob's guidance the department grew rapidly. He made significant contributions to knowledge on concussion and secondary nerve degeneration and became a doyen of neuropathology.Jakob was the author of five monographs and nearly 80 scientific papers. His neuropathological research contributed greatly to the delineation of several diseases, including multiple sclerosis and Friedreich's ataxia. He first recognised and described Alper's disease and Creutzfeldt–Jakob disease (named along with Munich neuropathologist Hans Gerhard Creutzfeldt). He gained experience in neurosyphilis, having a 200-bed ward devoted entirely to that disorder. Jakob made a lecture tour of the United States (1924) and South America (1928), of which, he wrote a paper on the neuropathology of yellow fever.He suffered from chronic osteomyelitis for the last seven years of his life. This eventually caused a retroperitoneal abscess and paralytic ileus from which he died following operation. == Associated eponym == Creutzfeldt–Jakob disease: A very rare and incurable degenerative neurological disease. It is the most common form of transmissible spongiform encephalopathies caused by prions. Eponym introduced by Walther Spielmeyer in 1922. == Bibliography == Die extrapyramidalen Erkrankungen.

### Instruction: retrieve labels for this: Argon is a chemical element with symbol Ar and atomic number 18. It is in group 18 of the periodic table and is a noble gas. Argon is the third-most abundant gas in the Earth's atmosphere, at 0.934% (9340 ppmv). It is more than twice as abundant as water vapor (which averages about 4000 ppmv, but varies greatly), 23 times as abundant as carbon dioxide (400 ppmv), and more than 500 times as abundant as neon (18 ppmv). Argon is the most abundant noble gas in Earth's crust, comprising 0.00015% of the crust. Nearly all of the argon in the Earth's atmosphere is radiogenic argon-40, derived from the decay of potassium-40 in the Earth's crust. In the universe, argon-36 is by far the most common argon isotope, as it is the most easily produced by stellar nucleosynthesis in supernovas. The name "argon" is derived from the Greek word ἀργόν, neuter singular form of ἀργός meaning "lazy" or "inactive", as a reference to the fact that the element undergoes almost no chemical reactions. The complete octet (eight electrons) in the outer atomic shell makes argon stable and resistant to bonding with other elements. Its triple point temperature of 83.8058 K is a defining fixed point in the International Temperature Scale of 1990. Argon is produced industrially by the fractional distillation of liquid air. Argon is mostly used as an inert shielding gas in welding and other high-temperature industrial processes where ordinarily unreactive substances become reactive; for example, an argon atmosphere is used in graphite electric furnaces to prevent the graphite from burning. Argon is also used in incandescent, fluorescent lighting, and other gas-discharge tubes. Argon makes a distinctive blue-green gas laser. Argon is also used in fluorescent glow starters. == Characteristics == Argon has approximately the same solubility in water as oxygen and is 2.5 times more soluble in water than nitrogen. Argon is colorless, odorless, nonflammable and nontoxic as a solid, liquid or gas. Argon is chemically inert under most conditions and forms no confirmed stable compounds at room temperature. Although argon is a noble gas, it can form some compounds under various extreme conditions. Argon fluorohydride (HArF), a compound of argon with fluorine and hydrogen that is stable below 17 K (−256.1 °C; −429.1 °F), has been demonstrated. Although the neutral ground-state chemical compounds of argon are presently limited to HArF, argon can form clathrates with water when atoms of argon are trapped in a lattice of water molecules. Ions, such as ArH+, and excited-state complexes, such as ArF, have been demonstrated. Theoretical calculation predicts several more argon compounds that should be stable but have not yet been synthesized. == History == Argon (Greek ἀργόν, neuter singular form of ἀργός meaning "lazy" or "inactive"), is named in reference to its chemical inactivity. This chemical property of this first noble gas to be discovered impressed the namers. An unreactive gas was suspected to be a component of air by Henry Cavendish in 1785. Argon was first isolated from air in 1894 by Lord Rayleigh and Sir William Ramsay at University College London by removing oxygen, carbon dioxide, water, and nitrogen from a sample of clean air. They had determined that nitrogen produced from chemical compounds was 0.5% lighter than nitrogen from the atmosphere. The difference was slight, but it was important enough to attract their attention for many months. They concluded that there was another gas in the air mixed in with the nitrogen. Argon was also encountered in 1882 through independent research of H. F. Newall and W. N. Hartley. Each observed new lines in the emission spectrum of air that did not match known elements. Until 1957, the symbol for argon was "A", but now is "Ar". == Occurrence == Argon constitutes 0.934% by volume and 1.288% by mass of the Earth's atmosphere, and air is the primary industrial source of purified argon products. Argon is isolated from air by fractionation, most commonly by cryogenic fractional distillation, a process that also produces purified nitrogen, oxygen, neon, krypton and xenon. The Earth's crust and seawater contain 1.2 ppm and 0.45 ppm of argon, respectively. == Isotopes == The main isotopes of argon found on Earth are 40Ar (99.6%), 36Ar (0.34%), and 38Ar (0.06%). Naturally occurring 40K, with a half-life of 1.25×109 years, decays to stable 40Ar (11.2%) by electron capture or positron emission, and also to stable 40Ca (88.8%) by beta decay. These properties and ratios are used to determine the age of rocks by K–Ar dating.In the Earth's atmosphere, 39Ar is made by cosmic ray activity, primarily by neutron capture of 40Ar followed by two-neutron emission. In the subsurface environment, it is also produced through neutron capture by 39K, followed by proton emission. 37Ar is created from the neutron capture by 40Ca followed by an alpha particle emission as a result of subsurface nuclear explosions. It has a half-life of 35 days.Between locations in the Solar System, the isotopic composition of argon varies greatly. Where the major source of argon is the decay of 40K in rocks, 40Ar will be the dominant isotope, as it is on Earth. Argon produced directly by stellar nucleosynthesis, is dominated by the alpha-process nuclide 36Ar. Correspondingly, solar argon contains 84.6% 36Ar (according to solar wind measurements), and the ratio of the three isotopes 36Ar : 38Ar : 40Ar in the atmospheres of the outer planets is 8400 : 1600 : 1. This contrasts with the low abundance of primordial 36Ar in Earth's atmosphere, which is only 31.5 ppmv (= 9340 ppmv × 0.337%), comparable with that of neon (18.18 ppmv) on Earth and with interplanetary gasses, measured by probes. The atmospheres of Mars, Mercury and Titan (the largest moon of Saturn) contain argon, predominantly as 40Ar, and its content may be as high as 1.93% (Mars).The predominance of radiogenic 40Ar is the reason the standard atomic weight of terrestrial argon is greater than that of the next element, potassium, a fact that was puzzling when argon was discovered. Mendeleev positioned the elements on his periodic table in order of atomic weight, but the inertness of argon suggested a placement before the reactive alkali metal. Henry Moseley later solved this problem by showing that the periodic table is actually arranged in order of atomic number (see History of the periodic table). == Compounds == Argon's complete octet of electrons indicates full s and p subshells. This full valence shell makes argon very stable and extremely resistant to bonding with other elements. Before 1962, argon and the other noble gases were considered to be chemically inert and unable to form compounds; however, compounds of the heavier noble gases have since been synthesized. The first argon compound with tungsten pentacarbonyl, W(CO)5Ar, was isolated in 1975. However it was not widely recognised at that time. In August 2000, another argon compound, argon fluorohydride (HArF), was formed by researchers at the University of Helsinki, by shining ultraviolet light onto frozen argon containing a small amount of hydrogen fluoride with caesium iodide. This discovery caused the recognition that argon could form weakly bound compounds, even though it was not the first. It is stable up to 17 kelvins (−256 °C). The metastable ArCF2+2 dication, which is valence-isoelectronic with carbonyl fluoride and phosgene, was observed in 2010. Argon-36, in the form of argon hydride (argonium) ions, has been detected in interstellar medium associated with the Crab Nebula supernova; this was the first noble-gas molecule detected in outer space.Solid argon hydride (Ar(H2)2) has the same crystal structure as the MgZn2 Laves phase. It forms at pressures between 4.3 and 220 GPa, though Raman measurements suggest that the H2 molecules in Ar(H2)2 dissociate above 175 GPa. == Production == === Industrial === Argon is produced industrially by the fractional distillation of liquid air in a cryogenic air separation unit; a process that separates liquid nitrogen, which boils at 77.3 K, from argon, which boils at 87.3 K, and liquid oxygen, which boils at 90.2 K. About 700,000 tonnes of argon are produced worldwide every year. === In radioactive decays === 40Ar, the most abundant isotope of argon, is produced by the decay of 40K with a half-life of 1.25×109 years by electron capture or positron emission. Because of this, it is used in potassium–argon dating to determine the age of rocks. == Applications == Argon has several desirable properties: Argon is a chemically inert gas. Argon is the cheapest alternative when nitrogen is not sufficiently inert. Argon has low thermal conductivity. Argon has electronic properties (ionization and/or the emission spectrum) desirable for some applications.Other noble gases would be equally suitable for most of these applications, but argon is by far the cheapest. Argon is inexpensive, since it occurs naturally in air and is readily obtained as a byproduct of cryogenic air separation in the production of liquid oxygen and liquid nitrogen: the primary constituents of air are used on a large industrial scale. The other noble gases (except helium) are produced this way as well, but argon is the most plentiful by far. The bulk of argon applications arise simply because it is inert and relatively cheap. === Industrial processes === Argon is used in some high-temperature industrial processes where ordinarily non-reactive substances become reactive. For example, an argon atmosphere is used in graphite electric furnaces to prevent the graphite from burning. For some of these processes, the presence of nitrogen or oxygen gases might cause defects within the material. Argon is used in some types of arc welding such as gas metal arc welding and gas tungsten arc welding, as well as in the processing of titanium and other reactive elements. An argon atmosphere is also used for growing crystals of silicon and germanium. Argon is used in the poultry industry to asphyxiate birds, either for mass culling following disease outbreaks, or as a means of slaughter more humane than the electric bath. Argon is denser than air and displaces oxygen close to the ground during gassing. Its non-reactive nature makes it suitable in a food product, and since it replaces oxygen within the dead bird, argon also enhances shelf life.Argon is sometimes used for extinguishing fires where valuable equipment may be damaged by water or foam. === Scientific research === Liquid argon is used as the target for neutrino experiments and direct dark matter searches. The interaction between the hypothetical WIMPs and an argon nucleus produces scintillation light that is detected by photomultiplier tubes. Two-phase detectors containing argon gas are used to detect the ionized electrons produced during the WIMP–nucleus scattering. As with most other liquefied noble gases, argon has a high scintillation light yield (about 51 photons/keV), is transparent to its own scintillation light, and is relatively easy to purify. Compared to xenon, argon is cheaper and has a distinct scintillation time profile, which allows the separation of electronic recoils from nuclear recoils. On the other hand, its intrinsic beta-ray background is larger due to 39Ar contamination, unless one uses argon from underground sources, which has much less 39Ar contamination. Most of the argon in the Earth’s atmosphere was produced by electron capture of long-lived 40K (40K + e− → 40Ar + ν) present in natural potassium within the Earth. The 39Ar activity in the atmosphere is maintained by cosmogenic production through the knockout reaction 40Ar(n,2n)39Ar and similar reactions. The half-life of 39Ar is only 269 years. As a result, the underground Ar, shielded by rock and water, has much less 39Ar contamination. Dark-matter detectors currently operating with liquid argon include DarkSide, WArP, ArDM, microCLEAN and DEAP. Neutrino experiments include ICARUS and MicroBooNE, both of which use high-purity liquid argon in a time projection chamber for fine grained three-dimensional imaging of neutrino interactions. === Preservative === Argon is used to displace oxygen- and moisture-containing air in packaging material to extend the shelf-lives of the contents (argon has the European food additive code E938). Aerial oxidation, hydrolysis, and other chemical reactions that degrade the products are retarded or prevented entirely. High-purity chemicals and pharmaceuticals are sometimes packed and sealed in argon. In winemaking, argon is used in a variety of activities to provide a barrier against oxygen at the liquid surface, which can spoil wine by fueling both microbial metabolism (as with acetic acid bacteria) and standard redox chemistry. Argon is sometimes used as the propellant in aerosol cans for such products as varnish, polyurethane, and paint, and to displace air when preparing a container for storage after opening.Since 2002, the American National Archives stores important national documents such as the Declaration of Independence and the Constitution within argon-filled cases to inhibit their degradation. Argon is preferable to the helium that had been used in the preceding five decades, because helium gas escapes through the intermolecular pores in most containers and must be regularly replaced. === Laboratory equipment === Argon may be used as the inert gas within Schlenk lines and gloveboxes. Argon is preferred to less expensive nitrogen in cases where nitrogen may react with the reagents or apparatus. Argon may be used as the carrier gas in gas chromatography and in electrospray ionization mass spectrometry; it is the gas of choice for the plasma used in ICP spectroscopy. Argon is preferred for the sputter coating of specimens for scanning electron microscopy. Argon gas is also commonly used for sputter deposition of thin films as in microelectronics and for wafer cleaning in microfabrication. === Medical use === Cryosurgery procedures such as cryoablation use liquid argon to destroy tissue such as cancer cells. It is used in a procedure called "argon-enhanced coagulation", a form of argon plasma beam electrosurgery. The procedure carries a risk of producing gas embolism and has resulted in the death of at least one patient.Blue argon lasers are used in surgery to weld arteries, destroy tumors, and correct eye defects.Argon has also been used experimentally to replace nitrogen in the breathing or decompression mix known as Argox, to speed the elimination of dissolved nitrogen from the blood. === Lighting === Incandescent lights are filled with argon, to preserve the filaments at high temperature from oxidation. It is used for the specific way it ionizes and emits light, such as in plasma globes and calorimetry in experimental particle physics. Gas-discharge lamps filled with pure argon provide lilac/violet light; with argon and some mercury, blue light. Argon is also used for blue and green argon-ion lasers. === Miscellaneous uses === Argon is used for thermal insulation in energy-efficient windows. Argon is also used in technical scuba diving to inflate a dry suit because it is inert and has low thermal conductivity.Argon is used as a propellant in the development of the Variable Specific Impulse Magnetoplasma Rocket (VASIMR). Compressed argon gas is allowed to expand, to cool the seeker heads of some versions of the AIM-9 Sidewinder missile and other missiles that use cooled thermal seeker heads. The gas is stored at high pressure.Argon-39, with a half-life of 269 years, has been used for a number of applications, primarily ice core and ground water dating. Also, potassium–argon dating and related argon-argon dating is used to date sedimentary, metamorphic, and igneous rocks.Argon has been used by athletes as a doping agent to simulate hypoxic conditions. In 2014, the World Anti-Doping Agency (WADA) added argon and xenon to the list of prohibited substances and methods, although at this time there is no reliable test for abuse. == Safety == Although argon is non-toxic, it is 38% denser than air and therefore considered a dangerous asphyxiant in closed areas. It is difficult to detect because it is colorless, odorless, and tasteless. A 1994 incident, in which a man was asphyxiated after entering an argon-filled section of oil pipe under construction in Alaska, highlights the dangers of argon tank leakage in confined spaces and emphasizes the need for proper use, storage and handling. == See also == Industrial gas Oxygen–argon ratio, a ratio of two physically similar gases, which has importance in various sectors. == References == == Further reading == Brown, T.

### Instruction: retrieve labels for this: Antimony is a chemical element with symbol Sb (from Latin: stibium) and atomic number 51. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb2S3). Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name, kohl. Metallic antimony was also known, but it was erroneously identified as lead upon its discovery. The earliest known description of the metal in the West was written in 1540 by Vannoccio Biringuccio. For some time, China has been the largest producer of antimony and its compounds, with most production coming from the Xikuangshan Mine in Hunan. The industrial methods for refining antimony are roasting and reduction with carbon or direct reduction of stibnite with iron. The largest applications for metallic antimony is an alloy with lead and tin and the lead antimony plates in lead–acid batteries. Alloys of lead and tin with antimony have improved properties for solders, bullets, and plain bearings. Antimony compounds are prominent additives for chlorine and bromine-containing fire retardants found in many commercial and domestic products. An emerging application is the use of antimony in microelectronics. == Characteristics == === Properties === Antimony is a member of group 15 of the periodic table, one of the elements called pnictogens, and has an electronegativity of 2.05. In accordance with periodic trends, it is more electronegative than tin or bismuth, and less electronegative than tellurium or arsenic. Antimony is stable in air at room temperature, but reacts with oxygen if heated to produce antimony trioxide, Sb2O3.Antimony is a silvery, lustrous gray metalloid with a Mohs scale hardness of 3, which is too soft to make hard objects; coins of antimony were issued in China's Guizhou province in 1931 but the durability was poor and the minting was soon discontinued. Antimony is resistant to attack by acids. Four allotropes of antimony are known: a stable metallic form and three metastable forms (explosive, black and yellow). Elemental antimony is a brittle, silver-white shiny metalloid. When slowly cooled, molten antimony crystallizes in a trigonal cell, isomorphic with the gray allotrope of arsenic. A rare explosive form of antimony can be formed from the electrolysis of antimony trichloride. When scratched with a sharp implement, an exothermic reaction occurs and white fumes are given off as metallic antimony forms; when rubbed with a pestle in a mortar, a strong detonation occurs. Black antimony is formed upon rapid cooling of antimony vapor. It has the same crystal structure as red phosphorus and black arsenic, it oxidizes in air and may ignite spontaneously. At 100 °C, it gradually transforms into the stable form. The yellow allotrope of antimony is the most unstable. It has only been generated by oxidation of stibine (SbH3) at −90 °C. Above this temperature and in ambient light, this metastable allotrope transforms into the more stable black allotrope.Elemental antimony adopts a layered structure (space group R3m No. 166) in which layers consist of fused, ruffled, six-membered rings. The nearest and next-nearest neighbors form an irregular octahedral complex, with the three atoms in each double layer slightly closer than the three atoms in the next. This relatively close packing leads to a high density of 6.697 g/cm3, but the weak bonding between the layers leads to the low hardness and brittleness of antimony. === Isotopes === Antimony has two stable isotopes: 121Sb with a natural abundance of 57.36% and 123Sb with a natural abundance of 42.64%. It also has 35 radioisotopes, of which the longest-lived is 125Sb with a half-life of 2.75 years. In addition, 29 metastable states have been characterized. The most stable of these is 120m1Sb with a half-life of 5.76 days. Isotopes that are lighter than the stable 123Sb tend to decay by β+ decay, and those that are heavier tend to decay by β− decay, with some exceptions. === Occurrence === The abundance of antimony in the Earth's crust is estimated to be 0.2 to 0.5 parts per million, comparable to thallium at 0.5 parts per million and silver at 0.07 ppm. Even though this element is not abundant, it is found in more than 100 mineral species. Antimony is sometimes found natively (e.g. on Antimony Peak), but more frequently it is found in the sulfide stibnite (Sb2S3) which is the predominant ore mineral. == Compounds == Antimony compounds are often classified according to their oxidation state: Sb(III) and Sb(V). The +5 oxidation state is more stable. === Oxides and hydroxides === Antimony trioxide is formed when antimony is burnt in air. In the gas phase, the molecule of the compound is Sb4O6, but it polymerizes upon condensing. Antimony pentoxide (Sb4O10) can be formed only by oxidation with concentrated nitric acid. Antimony also forms a mixed-valence oxide, antimony tetroxide (Sb2O4), which features both Sb(III) and Sb(V). Unlike oxides of phosphorus and arsenic, these oxides are amphoteric, do not form well-defined oxoacids, and react with acids to form antimony salts. Antimonous acid Sb(OH)3 is unknown, but the conjugate base sodium antimonite ([Na3SbO3]4) forms upon fusing sodium oxide and Sb4O6. Transition metal antimonites are also known. Antimonic acid exists only as the hydrate HSb(OH)6, forming salts as the antimonate anion Sb(OH)−6. When a solution containing this anion is dehydrated, the precipitate contains mixed oxides.Many antimony ores are sulfides, including stibnite (Sb2S3), pyrargyrite (Ag3SbS3), zinkenite, jamesonite, and boulangerite. Antimony pentasulfide is non-stoichiometric and features antimony in the +3 oxidation state and S-S bonds. Several thioantimonides are known, such as [Sb6S10]2− and [Sb8S13]2−. === Halides === Antimony forms two series of halides: SbX3 and SbX5. The trihalides SbF3, SbCl3, SbBr3, and SbI3 are all molecular compounds having trigonal pyramidal molecular geometry. The trifluoride SbF3 is prepared by the reaction of Sb2O3 with HF: Sb2O3 + 6 HF → 2 SbF3 + 3 H2OIt is Lewis acidic and readily accepts fluoride ions to form the complex anions SbF−4 and SbF2−5. Molten SbF3 is a weak electrical conductor. The trichloride SbCl3 is prepared by dissolving Sb2S3 in hydrochloric acid: Sb2S3 + 6 HCl → 2 SbCl3 + 3 H2S The pentahalides SbF5 and SbCl5 have trigonal bipyramidal molecular geometry in the gas phase, but in the liquid phase, SbF5 is polymeric, whereas SbCl5 is monomeric. SbF5 is a powerful Lewis acid used to make the superacid fluoroantimonic acid ("H2SbF7"). Oxyhalides are more common for antimony than for arsenic and phosphorus. Antimony trioxide dissolves in concentrated acid to form oxoantimonyl compounds such as SbOCl and (SbO)2SO4. === Antimonides, hydrides, and organoantimony compounds === Compounds in this class generally are described as derivatives of Sb3−. Antimony forms antimonides with metals, such as indium antimonide (InSb) and silver antimonide (Ag3Sb). The alkali metal and zinc antimonides, such as Na3Sb and Zn3Sb2, are more reactive. Treating these antimonides with acid produces the highly unstable gas stibine, SbH3: Sb3− + 3 H+ → SbH3Stibine can also be produced by treating Sb3+ salts with hydride reagents such as sodium borohydride. Stibine decomposes spontaneously at room temperature. Because stibine has a positive heat of formation, it is thermodynamically unstable and thus antimony does not react with hydrogen directly.Organoantimony compounds are typically prepared by alkylation of antimony halides with Grignard reagents. A large variety of compounds are known with both Sb(III) and Sb(V) centers, including mixed chloro-organic derivatives, anions, and cations. Examples include Sb(C6H5)3 (triphenylstibine), Sb2(C6H5)4 (with an Sb-Sb bond), and cyclic [Sb(C6H5)]n. Pentacoordinated organoantimony compounds are common, examples being Sb(C6H5)5 and several related halides. == History == Antimony(III) sulfide, Sb2S3, was recognized in predynastic Egypt as an eye cosmetic (kohl) as early as about 3100 BC, when the cosmetic palette was invented.An artifact, said to be part of a vase, made of antimony dating to about 3000 BC was found at Telloh, Chaldea (part of present-day Iraq), and a copper object plated with antimony dating between 2500 BC and 2200 BC has been found in Egypt. Austen, at a lecture by Herbert Gladstone in 1892 commented that "we only know of antimony at the present day as a highly brittle and crystalline metal, which could hardly be fashioned into a useful vase, and therefore this remarkable 'find' (artifact mentioned above) must represent the lost art of rendering antimony malleable."Moorey was unconvinced the artifact was indeed a vase, mentioning that Selimkhanov, after his analysis of the Tello object (published in 1975), "attempted to relate the metal to Transcaucasian natural antimony" (i.e. native metal) and that "the antimony objects from Transcaucasia are all small personal ornaments." This weakens the evidence for a lost art "of rendering antimony malleable."The Roman scholar Pliny the Elder described several ways of preparing antimony sulfide for medical purposes in his treatise Natural History. Pliny the Elder also made a distinction between "male" and "female" forms of antimony; the male form is probably the sulfide, while the female form, which is superior, heavier, and less friable, has been suspected to be native metallic antimony.The Roman naturalist Pedanius Dioscorides mentioned that antimony sulfide could be roasted by heating by a current of air. It is thought that this produced metallic antimony. The first description of a procedure for isolating antimony is in the 1540 book De la pirotechnia by Vannoccio Biringuccio, predating the more famous 1556 book by Agricola, De re metallica. In this context Agricola has been often incorrectly credited with the discovery of metallic antimony. The book Currus Triumphalis Antimonii (The Triumphal Chariot of Antimony), describing the preparation of metallic antimony, was published in Germany in 1604. It was purported to be written by a Benedictine monk, writing under the name Basilius Valentinus in the 15th century; if it were authentic, which it is not, it would predate Biringuccio.The metal antimony was known to German chemist Andreas Libavius in 1615 who obtained it by adding iron to a molten mixture of antimony sulfide, salt and potassium tartrate. This procedure produced antimony with a crystalline or starred surface.With the advent of challenges to phlogiston theory, it was recognized that antimony is an element forming sulfides, oxides, and other compounds, as do other metals.The first natural occurrence of pure antimony in the Earth's crust was described by the Swedish scientist and local mine district engineer Anton von Swab in 1783; the type-sample was collected from the Sala Silver Mine in the Bergslagen mining district of Sala, Västmanland, Sweden. === Etymology === The medieval Latin form, from which the modern languages and late Byzantine Greek take their names for antimony, is antimonium. The origin of this is uncertain; all suggestions have some difficulty either of form or interpretation. The popular etymology, from ἀντίμοναχός anti-monachos or French antimoine, still has adherents; this would mean "monk-killer", and is explained by many early alchemists being monks, and antimony being poisonous.Another popular etymology is the hypothetical Greek word ἀντίμόνος antimonos, "against aloneness", explained as "not found as metal", or "not found unalloyed". Lippmann conjectured a hypothetical Greek word ανθήμόνιον anthemonion, which would mean "floret", and cites several examples of related Greek words (but not that one) which describe chemical or biological efflorescence.The early uses of antimonium include the translations, in 1050–1100, by Constantine the African of Arabic medical treatises. Several authorities believe antimonium is a scribal corruption of some Arabic form; Meyerhof derives it from ithmid; other possibilities include athimar, the Arabic name of the metalloid, and a hypothetical as-stimmi, derived from or parallel to the Greek.The standard chemical symbol for antimony (Sb) is credited to Jöns Jakob Berzelius, who derived the abbreviation from stibium.The ancient words for antimony mostly have, as their chief meaning, kohl, the sulfide of antimony. The Egyptians called antimony mśdmt; in hieroglyphs, the vowels are uncertain, but an Arabic tradition holds that the word is ميسديميت mesdemet; the Coptic form of the word is ⲥⲧⲏⲙ (stēm). The Greek word, στίμμι stimmi, is probably a loan word from Arabic or from Egyptian stm and is used by Attic tragic poets of the 5th century BC. Later Greeks also used στἰβι stibi, as did Celsus and Pliny, writing in Latin, in the first century AD. Pliny also gives the names stimi [sic], larbaris, alabaster, and the "very common" platyophthalmos, "wide-eye" (from the effect of the cosmetic). Later Latin authors adapted the word to Latin as stibium. The Arabic word for the substance, as opposed to the cosmetic, can appear as إثمد ithmid, athmoud, othmod, or uthmod. Littré suggests the first form, which is the earliest, derives from stimmida, an accusative for stimmi. == Production == === Top producers and production volumes === The British Geological Survey (BGS) reported that in 2005 China was the top producer of antimony with approximately 84% of the world share, followed at a distance by South Africa, Bolivia and Tajikistan. Xikuangshan Mine in Hunan province has the largest deposits in China with an estimated deposit of 2.1 million metric tons.In 2016, according to the US Geological Survey, China accounted for 76.9% of total antimony production, followed in second place by Russia with 6.9% and Tajikistan with 6.2%. Chinese production of antimony is expected to decline in the future as mines and smelters are closed down by the government as part of pollution control. Especially due to a new environmental protection law having gone into effect on January 2015 and revised “Emission Standards of Pollutants for Stanum, Antimony, and Mercury” having gone into effect, hurdles for economic production are higher. According to the National Bureau of Statistics in China, by September 2015 50% of antimony production capacity in the Hunan province (the province with biggest antimony reserves in China) had not been used.Reported production of antimony in China has fallen and is unlikely to increase in the coming years, according to the Roskill report. No significant antimony deposits in China have been developed for about ten years, and the remaining economic reserves are being rapidly depleted.The world's largest antimony producers, according to Roskill, are listed below: === Reserves === According to statistics from the USGS, current global reserves of antimony will be depleted in 13 years. However, the USGS expects more resources will be found. === Production process === The extraction of antimony from ores depends on the quality and composition of the ore. Most antimony is mined as the sulfide; lower-grade ores are concentrated by froth flotation, while higher-grade ores are heated to 500–600 °C, the temperature at which stibnite melts and separates from the gangue minerals. Antimony can be isolated from the crude antimony sulfide by reduction with scrap iron: Sb2S3 + 3 Fe → 2 Sb + 3 FeSThe sulfide is converted to an oxide; the product is then roasted, sometimes for the purpose of vaporizing the volatile antimony(III) oxide, which is recovered. This material is often used directly for the main applications, impurities being arsenic and sulfide. Antimony is isolated from the oxide by a carbothermal reduction: 2 Sb2O3 + 3 C → 4 Sb + 3 CO2The lower-grade ores are reduced in blast furnaces while the higher-grade ores are reduced in reverberatory furnaces. === Supply risk and critical mineral rankings === Antimony has consistently been ranked high in European and US Risk Lists concerning criticality of the element indicating the relative risk to the supply of chemical elements or element groups required to maintain the current economy and lifestyle. With most of the antimony imported into Europe and the US coming from China, Chinese production is critical to supply. As China is revising and increasing environmental control standards, antimony production is becoming increasingly restricted. Additionally Chinese export quotas for antimony have been decreasing in the past years. These two factors increase supply risk for both Europe and US. ==== Europe ==== According to the BGS Risk List 2015, antimony is ranked second highest (after rare earth elements) on the relative supply risk index. This indicates that it has currently the second highest supply risk for chemical elements or element groups which are of economic value to the British economy and lifestyle. Furthermore, antimony was identified as one of 20 critical raw materials for the EU in a report published in 2014 (which revised the initial report published in 2011). As seen in Figure xxx antimony maintains high supply risk relative to its economic importance. 92% of the antimony is imported from China, which is a significantly high concentration of production. ==== U.S. ==== Much analysis has been conducted in the U.S. toward defining which metals should be called strategic or critical to the nation's security. Exact definitions do not exist, and views as to what constitutes a strategic or critical mineral to U.S. security diverge.In 2015, no antimony was mined in the U.S. The metal is imported from foreign countries. From 2011-2014 68% of America's antimony came from China, 14% from India, 4% from Mexico, and 14% from other sources. There are no government stockpiles in place currently. The U.S. “Subcommittee on Critical and Strategic Mineral Supply Chains” has screened 78 mineral resources from 1996-2008. It found that a small subset of minerals including antimony has fallen into the category of potentially critical minerals consistently. In the future, a second assessment will be made of the found subset of minerals to identify which should be defined of significant risk and critical to U.S. interests. == Applications == About 60% of antimony is consumed in flame retardants, and 20% is used in alloys for batteries, plain bearings, and solders. === Flame retardants === Antimony is mainly used in the trioxide for flame-proofing compounds, always in combination with halogenated flame retardants except in halogen-containing polymers. The flame retarding effect of antimony trioxide is produced by the formation of halogenated antimony compounds, which react with hydrogen atoms, and probably also with oxygen atoms and OH radicals, thus inhibiting fire. Markets for these flame-retardants include children's clothing, toys, aircraft, and automobile seat covers. They are also added to polyester resins in fiberglass composites for such items as light aircraft engine covers. The resin will burn in the presence of an externally generated flame, but will extinguish when the external flame is removed. === Alloys === Antimony forms a highly useful alloy with lead, increasing its hardness and mechanical strength. For most applications involving lead, varying amounts of antimony are used as alloying metal. In lead–acid batteries, this addition improves plate strength and charging characteristics. It is used in antifriction alloys (such as Babbitt metal), in bullets and lead shot, electrical cable sheathing, type metal (for example, for linotype printing machines), solder (some "lead-free" solders contain 5% Sb), in pewter, and in hardening alloys with low tin content in the manufacturing of organ pipes. === Other applications === Three other applications consume nearly all the rest of the world's supply. One application is a stabilizer and a catalyst for the production of polyethyleneterephthalate. Another is a fining agent to remove microscopic bubbles in glass, mostly for TV screens; antimony ions interact with oxygen, suppressing the tendency of the latter to form bubbles. The third application is pigments.Antimony is increasingly being used in semiconductors as a dopant in n-type silicon wafers for diodes, infrared detectors, and Hall-effect devices. In the 1950s, the emitters and collectors of n-p-n alloy junction transistors were doped with tiny beads of a lead-antimony alloy. Indium antimonide is used as a material for mid-infrared detectors.Biology and medicine have few uses for antimony. Treatments containing antimony, known as antimonials, are used as emetics. Antimony compounds are used as antiprotozoan drugs. Potassium antimonyl tartrate, or tartar emetic, was once used as an anti-schistosomal drug from 1919 on. It was subsequently replaced by praziquantel. Antimony and its compounds are used in several veterinary preparations, such as anthiomaline and lithium antimony thiomalate, as a skin conditioner in ruminants. Antimony has a nourishing or conditioning effect on keratinized tissues in animals. Antimony-based drugs, such as meglumine antimoniate, are also considered the drugs of choice for treatment of leishmaniasis in domestic animals. Unfortunately, besides having low therapeutic indices, the drugs have minimal penetration of the bone marrow, where some of the Leishmania amastigotes reside, and curing the disease – especially the visceral form – is very difficult. Elemental antimony as an antimony pill was once used as a medicine. It could be reused by others after ingestion and elimination.Antimony(III) sulfide is used in the heads of some safety matches.Antimony sulfides help to stabilize the friction coefficient in automotive brake pad materials.Antimony is used in bullets, bullet tracers, paint, glass art, and as an opacifier in enamel. Antimony-124 is used together with beryllium in neutron sources; the gamma rays emitted by antimony-124 initiate the photodisintegration of beryllium. The emitted neutrons have an average energy of 24 keV. Natural antimony is used in startup neutron sources. == Precautions == The effects of antimony and its compounds on human and environmental health differ widely. The elemental antimony metal does not affect human and environmental health. Inhalation of antimony trioxide (and similar poorly soluble Sb(III) dust particles such as antimony dust) is considered harmful and suspected of causing cancer. However, these effects are only observed with female rats and after long-term exposure to high dust concentrations. The effects are hypothesized to be attributed to inhalation of poorly soluble Sb particles leading to impaired lung clearance, lung overload, inflammation and ultimately tumour formation, not to exposure to antimony ions (OECD, 2008). Antimony chlorides are corrosive to skin. The effects of antimony are not comparable to arsenic; this might be caused by the significant differences of uptake, metabolism and excretion between arsenic and antimony. For oral absorption, ICRP (1994) recommended values of 10% for tartar emetic and 1% for all other antimony compounds. Dermal absorption for metals is estimated at most 1% (HERAG, 2007). Inhalation absorption of antimony trioxide and other poorly soluble Sb(III) substances (such as antimony dust) is estimated at 6.8% (OECD, 2008), whereas a value <1% is derived for Sb(V) substances. Antimony(V) is not quantitatively reduced to antimony(III) in the cell, and both species exist simultaneously. Antimony is mainly excreted from the human body via urine. Antimony and its compounds do not cause acute human health effects, with the exception of antimony potassium tartrate ("tartar emetic"), a prodrug that is intentionally used to treat leishmaniasis patients. Prolonged skin contact with antimony dust may cause dermatitis. However, it was agreed at the European Union level that the skin rashes observed are not substance-specific, but most probably due to a physical blocking of sweat ducts (ECHA/PR/09/09, Helsinki, 6 July 2009). Antimony dust may also be explosive when dispersed in the air; when in a bulk solid it is not combustible.Antimony is incompatible with strong acids, halogenated acids, and oxidizers; when exposed to newly formed hydrogen it may form stibine (SbH3).The 8-hour time-weighted average (TWA) is set at 0.5 mg/m3 by the American Conference of Governmental Industrial Hygienists and by the Occupational Safety and Health Administration (OSHA) as a legal permissible exposure limit (PEL) in the workplace. The National Institute for Occupational Safety and Health (NIOSH) has set a recommended exposure limit (REL) of 0.5 mg/m3 as an 8 hour TWA. Antimony compounds are used as catalysts for polyethylene terephthalate (PET) production. Some studies report minor antimony leaching from PET bottles into liquids, but levels are below drinking water guidelines. Antimony concentrations in fruit juice concentrates were somewhat higher (up to 44.7 µg/L of antimony), but juices do not fall under the drinking water regulations. The drinking water guidelines are: World Health Organization: 20 µg/L Japan: 15 µg/L United States Environmental Protection Agency, Health Canada and the Ontario Ministry of Environment: 6 µg/L EU and German Federal Ministry of Environment: 5 µg/LThe TDI proposed by WHO is 6 µg antimony per kilogram of body weight. The IDLH (immediately dangerous to life and health) value for antimony is 50 mg/m3. === Toxicity === Certain compounds of antimony appear to be toxic, particularly antimony trioxide and antimony potassium tartrate. Effects may be similar to arsenic poisoning . Occupational exposure may cause respiratory irritation, pneumoconiosis, antimony spots on the skin, gastrointestinal symptoms and cardiac arrhythmias. In addition antimony trioxide is potentially carcinogenic to humans.Adverse health effects have been observed in humans and animals following inhalation, oral, or dermal exposure to antimony and antimony compounds. Antimony toxicity typically occurs either due to occupational exposure, during therapy or from accidental ingestion. It is unclear if antimony can enter the body through the skin. == See also == Phase change memory == Notes == == References == == Bibliography == Endlich, F. M. (1888).

### Instruction: retrieve labels for this: Actinium is a chemical element with symbol Ac and atomic number 89. It was discovered by Friedrich Oskar Giesel in 1902, who isolated the element the same year. Actinium gave the name to the actinide series, a group of 15 similar elements between actinium and lawrencium in the periodic table. It is also sometimes considered the first of the 7th-period transition metals, although lawrencium is less commonly given that position. Together with polonium, radium, and radon, actinium was one of the first non-primordial radioactive elements to be isolated. A soft, silvery-white radioactive metal, actinium reacts rapidly with oxygen and moisture in air forming a white coating of actinium oxide that prevents further oxidation. As with most lanthanides and many actinides, actinium assumes oxidation state +3 in nearly all its chemical compounds. Actinium is found only in traces in uranium and thorium ores as the isotope 227Ac, which decays with a half-life of 21.772 years, predominantly emitting beta and sometimes alpha particles, and 228Ac, which is beta active with a half-life of 6.15 hours. One tonne of natural uranium in ore contains about 0.2 milligrams of actinium-227, and one tonne of thorium contains about 5 nanograms of actinium-228. The close similarity of physical and chemical properties of actinium and lanthanum makes separation of actinium from the ore impractical. Instead, the element is prepared, in milligram amounts, by the neutron irradiation of 226Ra in a nuclear reactor. Owing to its scarcity, high price and radioactivity, actinium has no significant industrial use. Its current applications include a neutron source and an agent for radiation therapy targeting cancer cells in the body and killing them. == History == André-Louis Debierne, a French chemist, announced the discovery of a new element in 1899. He separated it from pitchblende residues left by Marie and Pierre Curie after they had extracted radium. In 1899, Debierne described the substance as similar to titanium and (in 1900) as similar to thorium. Friedrich Oskar Giesel independently discovered actinium in 1902 as a substance being similar to lanthanum and called it "emanium" in 1904. After a comparison of the substances half-lives determined by Debierne, Harriet Brooks in 1904, and Otto Hahn and Otto Sackur in 1905, Debierne's chosen name for the new element was retained because it had seniority, despite the contradicting chemical properties he claimed for the element at different times.Articles published in the 1970s and later suggest that Debierne's results published in 1904 conflict with those reported in 1899 and 1900. Furthermore, the now-known chemistry of actinium precludes its presence as anything other than a minor constituent of Debierne's 1899 and 1900 results; in fact, the chemical properties he reported make it likely that he had, instead, accidentally identified protactinium, which would not be discovered for another fourteen years, only to have it disappear due to its hydrolysis and adsorption onto his laboratory equipment. This has led some authors to advocate that Giesel alone should be credited with the discovery. A less confrontational vision of scientific discovery is proposed by Adloff. He suggests that hindsight criticism of the early publications should be mitigated by the then nascent state of radiochemistry: highlighting the prudence of Debierne's claims in the original papers, he notes that nobody can contend that Debierne's substance did not contain actinium. Debierne, who is now considered by the vast majority of historians as the discoverer, lost interest in the element and left the topic. Giesel, on the other hand, can rightfully be credited with the first preparation of radiochemically pure actinium and with the identification of its atomic number 89.The name actinium originates from the Ancient Greek aktis, aktinos (ακτίς, ακτίνος), meaning beam or ray. Its symbol Ac is also used in abbreviations of other compounds that have nothing to do with actinium, such as acetyl, acetate and sometimes acetaldehyde. == Properties == Actinium is a soft, silvery-white, radioactive, metallic element. Its estimated shear modulus is similar to that of lead. Owing to its strong radioactivity, actinium glows in the dark with a pale blue light, which originates from the surrounding air ionized by the emitted energetic particles. Actinium has similar chemical properties to lanthanum and other lanthanides, and therefore these elements are difficult to separate when extracting from uranium ores. Solvent extraction and ion chromatography are commonly used for the separation.The first element of the actinides, actinium gave the group its name, much as lanthanum had done for the lanthanides. The group of elements is more diverse than the lanthanides and therefore it was not until 1928 that Charles Janet proposed the most significant change to Dmitri Mendeleev's periodic table since the recognition of the lanthanides, by introducing the actinides, a move suggested again in 1945 by Glenn T. Seaborg.Actinium reacts rapidly with oxygen and moisture in air forming a white coating of actinium oxide that impedes further oxidation. As with most lanthanides and actinides, actinium exists in the oxidation state +3, and the Ac3+ ions are colorless in solutions. The oxidation state +3 originates from the [Rn]6d17s2 electronic configuration of actinium, with three valence electrons that are easily donated to give the stable closed-shell structure of the noble gas radon. The rare oxidation state +2 is only known for actinium dihydride (AcH2); even this may in reality be an electride compound like its lighter congener LaH2 and thus have actinium(III). == Chemical compounds == Only a limited number of actinium compounds are known including AcF3, AcCl3, AcBr3, AcOF, AcOCl, AcOBr, Ac2S3, Ac2O3 and AcPO4, due to actinium's intense radioactivity. Except for AcPO4, they are all similar to the corresponding lanthanum compounds. They all contain actinium in the oxidation state +3. In particular, the lattice constants of the analogous lanthanum and actinium compounds differ by only a few percent. Here a, b and c are lattice constants, No is space group number and Z is the number of formula units per unit cell. Density was not measured directly but calculated from the lattice parameters. === Oxides === Actinium oxide (Ac2O3) can be obtained by heating the hydroxide at 500 °C or the oxalate at 1100 °C, in vacuum. Its crystal lattice is isotypic with the oxides of most trivalent rare-earth metals. === Halides === Actinium trifluoride can be produced either in solution or in solid reaction. The former reaction is carried out at room temperature, by adding hydrofluoric acid to a solution containing actinium ions. In the latter method, actinium metal is treated with hydrogen fluoride vapors at 700 °C in an all-platinum setup. Treating actinium trifluoride with ammonium hydroxide at 900–1000 °C yields oxyfluoride AcOF. Whereas lanthanum oxyfluoride can be easily obtained by burning lanthanum trifluoride in air at 800 °C for an hour, similar treatment of actinium trifluoride yields no AcOF and only results in melting of the initial product. AcF3 + 2 NH3 + H2O → AcOF + 2 NH4FActinium trichloride is obtained by reacting actinium hydroxide or oxalate with carbon tetrachloride vapors at temperatures above 960 °C. Similar to oxyfluoride, actinium oxychloride can be prepared by hydrolyzing actinium trichloride with ammonium hydroxide at 1000 °C. However, in contrast to the oxyfluoride, the oxychloride could well be synthesized by igniting a solution of actinium trichloride in hydrochloric acid with ammonia.Reaction of aluminium bromide and actinium oxide yields actinium tribromide: Ac2O3 + 2 AlBr3 → 2 AcBr3 + Al2O3and treating it with ammonium hydroxide at 500 °C results in the oxybromide AcOBr. === Other compounds === Actinium hydride was obtained by reduction of actinium trichloride with potassium at 300 °C, and its structure was deduced by analogy with the corresponding LaH2 hydride. The source of hydrogen in the reaction was uncertain.Mixing monosodium phosphate (NaH2PO4) with a solution of actinium in hydrochloric acid yields white-colored actinium phosphate hemihydrate (AcPO4·0.5H2O), and heating actinium oxalate with hydrogen sulfide vapors at 1400 °C for a few minutes results in a black actinium sulfide Ac2S3. It may possibly be produced by acting with a mixture of hydrogen sulfide and carbon disulfide on actinium oxide at 1000 °C. == Isotopes == Naturally occurring actinium is composed of two radioactive isotopes; 227Ac (from the radioactive family of 235U) and 228Ac (a granddaughter of 232Th). 227Ac decays mainly as a beta emitter with a very small energy, but in 1.38% of cases it emits an alpha particle, so it can readily be identified through alpha spectrometry. Thirty-six radioisotopes have been identified, the most stable being 227Ac with a half-life of 21.772 years, 225Ac with a half-life of 10.0 days and 226Ac with a half-life of 29.37 hours. All remaining radioactive isotopes have half-lives that are less than 10 hours and the majority of them have half-lives shorter than one minute. The shortest-lived known isotope of actinium is 217Ac (half-life of 69 nanoseconds) which decays through alpha decay and electron capture. Actinium also has two known meta states. The most significant isotopes for chemistry are 225Ac, 227Ac, and 228Ac.Purified 227Ac comes into equilibrium with its decay products after about a half of year. It decays according to its 21.772-year half-life emitting mostly beta (98.62%) and some alpha particles (1.38%); the successive decay products are part of the actinium series. Owing to the low available amounts, low energy of its beta particles (maximum 44.8 keV) and low intensity of alpha radiation, 227Ac is difficult to detect directly by its emission and it is therefore traced via its decay products. The isotopes of actinium range in atomic weight from 206 u (206Ac) to 236 u (236Ac). == Occurrence and synthesis == Actinium is found only in traces in uranium ores – one tonne of uranium in ore contains about 0.2 milligrams of 227Ac – and in thorium ores, which contain about 5 nanograms of 228Ac per one tonne of thorium. The actinium isotope 227Ac is a transient member of the uranium-actinium series decay chain, which begins with the parent isotope 235U (or 239Pu) and ends with the stable lead isotope 207Pb. The isotope 228Ac is a transient member of the thorium series decay chain, which begins with the parent isotope 232Th and ends with the stable lead isotope 208Pb. Another actinium isotope (225Ac) is transiently present in the neptunium series decay chain, beginning with 237Np (or 233U) and ending with thallium (205Tl) and near-stable bismuth (209Bi); even though all primordial 237Np has decayed away, it is continuously produced by neutron knock-out reactions on natural 238U. The low natural concentration, and the close similarity of physical and chemical properties to those of lanthanum and other lanthanides, which are always abundant in actinium-bearing ores, render separation of actinium from the ore impractical, and complete separation was never achieved. Instead, actinium is prepared, in milligram amounts, by the neutron irradiation of 226Ra in a nuclear reactor. Ra 88 226 + n 0 1 ⟶ Ra 88 227 → 42.2 min β − Ac 89 227 {\displaystyle {\ce {^{226}_{88}Ra + ^{1}_{0}n -> ^{227}_{88}Ra ->[\beta^-][42.2 \ {\ce {min}}] ^{227}_{89}Ac}}} The reaction yield is about 2% of the radium weight. 227Ac can further capture neutrons resulting in small amounts of 228Ac. After the synthesis, actinium is separated from radium and from the products of decay and nuclear fusion, such as thorium, polonium, lead and bismuth. The extraction can be performed with thenoyltrifluoroacetone-benzene solution from an aqueous solution of the radiation products, and the selectivity to a certain element is achieved by adjusting the pH (to about 6.0 for actinium). An alternative procedure is anion exchange with an appropriate resin in nitric acid, which can result in a separation factor of 1,000,000 for radium and actinium vs. thorium in a two-stage process. Actinium can then be separated from radium, with a ratio of about 100, using a low cross-linking cation exchange resin and nitric acid as eluant.225Ac was first produced artificially at the Institute for Transuranium Elements (ITU) in Germany using a cyclotron and at St George Hospital in Sydney using a linac in 2000. This rare isotope has potential applications in radiation therapy and is most efficiently produced by bombarding a radium-226 target with 20–30 MeV deuterium ions. This reaction also yields 226Ac which however decays with a half-life of 29 hours and thus does not contaminate 225Ac.Actinium metal has been prepared by the reduction of actinium fluoride with lithium vapor in vacuum at a temperature between 1100 and 1300 °C. Higher temperatures resulted in evaporation of the product and lower ones lead to an incomplete transformation. Lithium was chosen among other alkali metals because its fluoride is most volatile. == Applications == Owing to its scarcity, high price and radioactivity, actinium currently has no significant industrial use.227Ac is highly radioactive and was therefore studied for use as an active element of radioisotope thermoelectric generators, for example in spacecraft. The oxide of 227Ac pressed with beryllium is also an efficient neutron source with the activity exceeding that of the standard americium-beryllium and radium-beryllium pairs. In all those applications, 227Ac (a beta source) is merely a progenitor which generates alpha-emitting isotopes upon its decay. Beryllium captures alpha particles and emits neutrons owing to its large cross-section for the (α,n) nuclear reaction: Be 4 9 + He 2 4 ⟶ C 6 12 + n 0 1 + γ {\displaystyle {\ce {^{9}_{4}Be + ^{4}_{2}He -> ^{12}_{6}C + ^{1}_{0}n + \gamma}}} The 227AcBe neutron sources can be applied in a neutron probe – a standard device for measuring the quantity of water present in soil, as well as moisture/density for quality control in highway construction. Such probes are also used in well logging applications, in neutron radiography, tomography and other radiochemical investigations. 225Ac is applied in medicine to produce 213Bi in a reusable generator or can be used alone as an agent for radiation therapy, in particular targeted alpha therapy (TAT). This isotope has a half-life of 10 days that makes it much more suitable for radiation therapy than 213Bi (half-life 46 minutes). Not only 225Ac itself, but also its daughters, emit alpha particles which kill cancer cells in the body. The major difficulty with application of 225Ac was that intravenous injection of simple actinium complexes resulted in their accumulation in the bones and liver for a period of tens of years. As a result, after the cancer cells were quickly killed by alpha particles from 225Ac, the radiation from the actinium and its daughters might induce new mutations. To solve this problem, 225Ac was bound to a chelating agent, such as citrate, ethylenediaminetetraacetic acid (EDTA) or diethylene triamine pentaacetic acid (DTPA). This reduced actinium accumulation in the bones, but the excretion from the body remained slow. Much better results were obtained with such chelating agents as HEHA (1,4,7,10,13,16-hexaazacyclohexadecane-N,N',N'`,N'``,N'``',N'``'`-hexaacetic acid) or DOTA (1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid) coupled to trastuzumab, a monoclonal antibody that interferes with the HER2/neu receptor. The latter delivery combination was tested on mice and proved to be effective against leukemia, lymphoma, breast, ovarian, neuroblastoma and prostate cancers.The medium half-life of 227Ac (21.77 years) makes it very convenient radioactive isotope in modeling the slow vertical mixing of oceanic waters. The associated processes cannot be studied with the required accuracy by direct measurements of current velocities (of the order 50 meters per year). However, evaluation of the concentration depth-profiles for different isotopes allows estimating the mixing rates. The physics behind this method is as follows: oceanic waters contain homogeneously dispersed 235U. Its decay product, 231Pa, gradually precipitates to the bottom, so that its concentration first increases with depth and then stays nearly constant. 231Pa decays to 227Ac; however, the concentration of the latter isotope does not follow the 231Pa depth profile, but instead increases toward the sea bottom. This occurs because of the mixing processes which raise some additional 227Ac from the sea bottom. Thus analysis of both 231Pa and 227Ac depth profiles allows researchers to model the mixing behavior. == Precautions == 227Ac is highly radioactive and experiments with it are carried out in a specially designed laboratory equipped with a tight glove box. When actinium trichloride is administered intravenously to rats, about 33% of actinium is deposited into the bones and 50% into the liver. Its toxicity is comparable to, but slightly lower than that of americium and plutonium. For trace quantities, fume hoods with good aeration suffice; for gram amounts, hot cells with shielding from the intense gamma radiation emitted by 227Ac are necessary. == See also == Actinium series == References == == Bibliography == Meyer, Gerd and Morss, Lester R.

### Instruction: retrieve labels for this: Americium is a synthetic chemical element with symbol Am and atomic number 95. It is a transuranic member of the actinide series, in the periodic table located under the lanthanide element europium, and thus by analogy was named after the Americas.Americium was first produced in 1944 by the group of Glenn T. Seaborg from Berkeley, California, at the Metallurgical Laboratory of the University of Chicago, a part of the Manhattan Project. Although it is the third element in the transuranic series, it was discovered fourth, after the heavier curium. The discovery was kept secret and only released to the public in November 1945. Most americium is produced by uranium or plutonium being bombarded with neutrons in nuclear reactors – one tonne of spent nuclear fuel contains about 100 grams of americium. It is widely used in commercial ionization chamber smoke detectors, as well as in neutron sources and industrial gauges. Several unusual applications, such as nuclear batteries or fuel for space ships with nuclear propulsion, have been proposed for the isotope 242mAm, but they are as yet hindered by the scarcity and high price of this nuclear isomer. Americium is a relatively soft radioactive metal with silvery appearance. Its common isotopes are 241Am and 243Am. In chemical compounds, americium usually assumes the oxidation state +3, especially in solutions. Several other oxidation states are known, which range from +2 to +7 and can be identified by their characteristic optical absorption spectra. The crystal lattice of solid americium and its compounds contain small intrinsic radiogenic defects, due to metamictization induced by self-irradiation with alpha particles, which accumulates with time; this can cause a drift of some material properties over time, more noticeable in older samples. == History == Although americium was likely produced in previous nuclear experiments, it was first intentionally synthesized, isolated and identified in late autumn 1944, at the University of California, Berkeley, by Glenn T. Seaborg, Leon O. Morgan, Ralph A. James, and Albert Ghiorso. They used a 60-inch cyclotron at the University of California, Berkeley. The element was chemically identified at the Metallurgical Laboratory (now Argonne National Laboratory) of the University of Chicago. Following the lighter neptunium, plutonium, and heavier curium, americium was the fourth transuranium element to be discovered. At the time, the periodic table had been restructured by Seaborg to its present layout, containing the actinide row below the lanthanide one. This led to americium being located right below its twin lanthanide element europium; it was thus by analogy named after the Americas: "The name americium (after the Americas) and the symbol Am are suggested for the element on the basis of its position as the sixth member of the actinide rare-earth series, analogous to europium, Eu, of the lanthanide series."The new element was isolated from its oxides in a complex, multi-step process. First plutonium-239 nitrate (239PuNO3) solution was coated on a platinum foil of about 0.5 cm2 area, the solution was evaporated and the residue was converted into plutonium dioxide (PuO2) by annealing. After cyclotron irradiation, the coating was dissolved with nitric acid, and then precipitated as the hydroxide using concentrated aqueous ammonia solution. The residue was dissolved in perchloric acid. Further separation was carried out by ion exchange, yielding a certain isotope of curium. The separation of curium and americium was so painstaking that those elements were initially called by the Berkeley group as pandemonium (from Greek for all demons or hell) and delirium (from Latin for madness).Initial experiments yielded four americium isotopes: 241Am, 242Am, 239Am and 238Am. Americium-241 was directly obtained from plutonium upon absorption of two neutrons. It decays by emission of a α-particle to 237Np; the half-life of this decay was first determined as 510±20 years but then corrected to 432.2 years. Pu 94 239 → ( n , γ ) Pu 94 240 → ( n , γ ) Pu 94 241 → 14.35 yr β − Am 95 241 ( → 432.2 yr α Np 93 237 ) {\displaystyle {\ce {^{239}_{94}Pu ->[{\ce {(n,\gamma)}}] ^{240}_{94}Pu ->[{\ce {(n,\gamma)}}] ^{241}_{94}Pu ->[\beta^-][14.35\ {\ce {yr}}] ^{241}_{95}Am}}\ \left({\ce {->[\alpha][432.2\ {\ce {yr}}] ^{237}_{93}Np}}\right)} The times are half-livesThe second isotope 242Am was produced upon neutron bombardment of the already-created 241Am. Upon rapid β-decay, 242Am converts into the isotope of curium 242Cm (which had been discovered previously). The half-life of this decay was initially determined at 17 hours, which was close to the presently accepted value of 16.02 h. Am 95 241 → ( n , γ ) Am 95 242 ( → 16.02 h β − Cm 96 242 ) {\displaystyle {\ce {^{241}_{95}Am ->[{\ce {(n,\gamma)}}] ^{242}_{95}Am}}\ \left({\ce {->[\beta^-][16.02\ {\ce {h}}] ^{242}_{96}Cm}}\right)} The discovery of americium and curium in 1944 was closely related to the Manhattan Project; the results were confidential and declassified only in 1945. Seaborg leaked the synthesis of the elements 95 and 96 on the U.S. radio show for children Quiz Kids five days before the official presentation at an American Chemical Society meeting on 11 November 1945, when one of the listeners asked whether any new transuranium element beside plutonium and neptunium had been discovered during the war. After the discovery of americium isotopes 241Am and 242Am, their production and compounds were patented listing only Seaborg as the inventor. The initial americium samples weighed a few micrograms; they were barely visible and were identified by their radioactivity. The first substantial amounts of metallic americium weighing 40–200 micrograms were not prepared until 1951 by reduction of americium(III) fluoride with barium metal in high vacuum at 1100 °C. == Occurrence == The longest-lived and most common isotopes of americium, 241Am and 243Am, have half-lives of 432.2 and 7,370 years, respectively. Therefore, any primordial americium (americium that was present on Earth during its formation) should have decayed by now. Existing americium is concentrated in the areas used for the atmospheric nuclear weapons tests conducted between 1945 and 1980, as well as at the sites of nuclear incidents, such as the Chernobyl disaster. For example, the analysis of the debris at the testing site of the first U.S. hydrogen bomb, Ivy Mike, (1 November 1952, Enewetak Atoll), revealed high concentrations of various actinides including americium; but due to military secrecy, this result was not published until later, in 1956. Trinitite, the glassy residue left on the desert floor near Alamogordo, New Mexico, after the plutonium-based Trinity nuclear bomb test on 16 July 1945, contains traces of americium-241. Elevated levels of americium were also detected at the crash site of a US Boeing B-52 bomber aircraft, which carried four hydrogen bombs, in 1968 in Greenland.In other regions, the average radioactivity of surface soil due to residual americium is only about 0.01 picocuries/g (0.37 mBq/g). Atmospheric americium compounds are poorly soluble in common solvents and mostly adhere to soil particles. Soil analysis revealed about 1,900 times higher concentration of americium inside sandy soil particles than in the water present in the soil pores; an even higher ratio was measured in loam soils.Americium is produced mostly artificially in small quantities, for research purposes. A tonne of spent nuclear fuel contains about 100 grams of various americium isotopes, mostly 241Am and 243Am. Their prolonged radioactivity is undesirable for the disposal, and therefore americium, together with other long-lived actinides, must be neutralized. The associated procedure may involve several steps, where americium is first separated and then converted by neutron bombardment in special reactors to short-lived nuclides. This procedure is well known as nuclear transmutation, but it is still being developed for americium. The transuranic elements from americium to fermium occurred naturally in the natural nuclear fission reactor at Oklo, but no longer do so. == Synthesis and extraction == === Isotope nucleosyntheses === Americium has been produced in small quantities in nuclear reactors for decades, and kilograms of its 241Am and 243Am isotopes have been accumulated by now. Nevertheless, since it was first offered for sale in 1962, its price, about 1,500 USD per gram of 241Am, remains almost unchanged owing to the very complex separation procedure. The heavier isotope 243Am is produced in much smaller amounts; it is thus more difficult to separate, resulting in a higher cost of the order 100,000–160,000 USD/g.Americium is not synthesized directly from uranium – the most common reactor material – but from the plutonium isotope 239Pu. The latter needs to be produced first, according to the following nuclear process: U 92 238 → ( n , γ ) U 92 239 → 23.5 min β − Np 93 239 → 2.3565 d β − Pu 94 239 {\displaystyle {\ce {^{238}_{92}U ->[{\ce {(n,\gamma)}}] ^{239}_{92}U ->[\beta^-][23.5 \ {\ce {min}}] ^{239}_{93}Np ->[\beta^-][2.3565 \ {\ce {d}}] ^{239}_{94}Pu}}} The capture of two neutrons by 239Pu (a so-called (n,γ) reaction), followed by a β-decay, results in 241Am: Pu 94 239 → 2 ( n , γ ) Pu 94 241 → 14.35 yr β − Am 95 241 {\displaystyle {\ce {^{239}_{94}Pu ->[{\ce {2(n,\gamma)}}] ^{241}_{94}Pu ->[\beta^-][14.35 \ {\ce {yr}}] ^{241}_{95}Am}}} The plutonium present in spent nuclear fuel contains about 12% of 241Pu. Because it spontaneously converts to 241Am, 241Pu can be extracted and may be used to generate further 241Am. However, this process is rather slow: half of the original amount of 241Pu decays to 241Am after about 15 years, and the 241Am amount reaches a maximum after 70 years.The obtained 241Am can be used for generating heavier americium isotopes by further neutron capture inside a nuclear reactor. In a light water reactor (LWR), 79% of 241Am converts to 242Am and 10% to its nuclear isomer 242mAm: { 79 % : Am 95 241 → ( n , γ ) Am 95 242 10 % : Am 95 241 → ( n , γ ) Am 95 242 m {\displaystyle {\begin{cases}79\%:&{\ce {^{241}_{95}Am ->[{\ce {(n,\gamma)}}] ^{242}_{95}Am}}\\10\%:&{\ce {^{241}_{95}Am ->[{\ce {(n,\gamma)}}] ^{242 m}_{95}Am}}\end{cases}}} Americium-242 has a half-life of only 16 hours, which makes its further up-conversion to 243Am, extremely inefficient. The latter isotope is produced instead in a process where 239Pu captures four neutrons under high neutron flux: Pu 94 239 → 4 ( n , γ ) 94 243 Pu → 4.956 h β − Am 95 243 {\displaystyle {\ce {^{239}_{94}Pu ->[{\ce {4(n,\gamma)}}] \ ^{243}_{94}Pu ->[\beta^-][4.956 \ {\ce {h}}] ^{243}_{95}Am}}} === Metal generation === Most synthesis routines yield a mixture of different actinide isotopes in oxide forms, from which isotopes of americium can be separated. In a typical procedure, the spent reactor fuel (e.g. MOX fuel) is dissolved in nitric acid, and the bulk of uranium and plutonium is removed using a PUREX-type extraction (Plutonium–URanium EXtraction) with tributyl phosphate in a hydrocarbon. The lanthanides and remaining actinides are then separated from the aqueous residue (raffinate) by a diamide-based extraction, to give, after stripping, a mixture of trivalent actinides and lanthanides. Americium compounds are then selectively extracted using multi-step chromatographic and centrifugation techniques with an appropriate reagent. A large amount of work has been done on the solvent extraction of americium. For example, a 2003 EU-funded project codenamed "EUROPART" studied triazines and other compounds as potential extraction agents. A bis-triazinyl bipyridine complex was proposed in 2009 as such a reagent is highly selective to americium (and curium). Separation of americium from the highly similar curium can be achieved by treating a slurry of their hydroxides in aqueous sodium bicarbonate with ozone, at elevated temperatures. Both Am and Cm are mostly present in solutions in the +3 valence state; whereas curium remains unchanged, americium oxidizes to soluble Am(IV) complexes which can be washed away.Metallic americium is obtained by reduction from its compounds. Americium(III) fluoride was first used for this purpose. The reaction was conducted using elemental barium as reducing agent in a water- and oxygen-free environment inside an apparatus made of tantalum and tungsten. 2 A m F 3 + 3 B a ⟶ 2 A m + 3 B a F 2 {\displaystyle \mathrm {2\ AmF_{3}\ +\ 3\ Ba\ \longrightarrow \ 2\ Am\ +\ 3\ BaF_{2}} } An alternative is the reduction of americium dioxide by metallic lanthanum or thorium: 3 A m O 2 + 4 L a ⟶ 3 A m + 2 L a 2 O 3 {\displaystyle \mathrm {3\ AmO_{2}\ +\ 4\ La\ \longrightarrow \ 3\ Am\ +\ 2\ La_{2}O_{3}} } == Physical properties == In the periodic table, americium is located to the right of plutonium, to the left of curium, and below the lanthanide europium, with which it shares many similarities in physical and chemical properties. Americium is a highly radioactive element. When freshly prepared, it has a silvery-white metallic lustre, but then slowly tarnishes in air. With a density of 12 g/cm3, americium is less dense than both curium (13.52 g/cm3) and plutonium (19.8 g/cm3); but has a higher density than europium (5.264 g/cm3)—mostly because of its higher atomic mass. Americium is relatively soft and easily deformable and has a significantly lower bulk modulus than the actinides before it: Th, Pa, U, Np and Pu. Its melting point of 1173 °C is significantly higher than that of plutonium (639 °C) and europium (826 °C), but lower than for curium (1340 °C).At ambient conditions, americium is present in its most stable α form which has a hexagonal crystal symmetry, and a space group P63/mmc with lattice parameters a = 346.8 pm and c = 1124 pm, and four atoms per unit cell. The crystal consists of a double-hexagonal close packing with the layer sequence ABAC and so is isotypic with α-lanthanum and several actinides such as α-curium. The crystal structure of americium changes with pressure and temperature. When compressed at room temperature to 5 GPa, α-Am transforms to the β modification, which has a face-centered cubic (fcc) symmetry, space group Fm3m and lattice constant a = 489 pm. This fcc structure is equivalent to the closest packing with the sequence ABC. Upon further compression to 23 GPa, americium transforms to an orthorhombic γ-Am structure similar to that of α-uranium. There are no further transitions observed up to 52 GPa, except for an appearance of a monoclinic phase at pressures between 10 and 15 GPa. There is no consistency on the status of this phase in the literature, which also sometimes lists the α, β and γ phases as I, II and III. The β-γ transition is accompanied by a 6% decrease in the crystal volume; although theory also predicts a significant volume change for the α-β transition, it is not observed experimentally. The pressure of the α-β transition decreases with increasing temperature, and when α-americium is heated at ambient pressure, at 770 °C it changes into an fcc phase which is different from β-Am, and at 1075 °C it converts to a body-centered cubic structure. The pressure-temperature phase diagram of americium is thus rather similar to those of lanthanum, praseodymium and neodymium.As with many other actinides, self-damage of the crystal lattice due to alpha-particle irradiation is intrinsic to americium. It is especially noticeable at low temperatures, where the mobility of the produced lattice defects is relatively low, by broadening of X-ray diffraction peaks. This effect makes somewhat uncertain the temperature of americium and some of its properties, such as electrical resistivity. So for americium-241, the resistivity at 4.2 K increases with time from about 2 µOhm·cm to 10 µOhm·cm after 40 hours, and saturates at about 16 µOhm·cm after 140 hours. This effect is less pronounced at room temperature, due to annihilation of radiation defects; also heating to room temperature the sample which was kept for hours at low temperatures restores its resistivity. In fresh samples, the resistivity gradually increases with temperature from about 2 µOhm·cm at liquid helium to 69 µOhm·cm at room temperature; this behavior is similar to that of neptunium, uranium, thorium and protactinium, but is different from plutonium and curium which show a rapid rise up to 60 K followed by saturation. The room temperature value for americium is lower than that of neptunium, plutonium and curium, but higher than for uranium, thorium and protactinium.Americium is paramagnetic in a wide temperature range, from that of liquid helium, to room temperature and above. This behavior is markedly different from that of its neighbor curium which exhibits antiferromagnetic transition at 52 K. The thermal expansion coefficient of americium is slightly anisotropic and amounts to (7.5±0.2)×10−6 /°C along the shorter a axis and (6.2±0.4)×10−6 /°C for the longer c hexagonal axis. The enthalpy of dissolution of americium metal in hydrochloric acid at standard conditions is −620.6±1.3 kJ/mol, from which the standard enthalpy change of formation (ΔfH°) of aqueous Am3+ ion is −621.2±2.0 kJ/mol. The standard potential Am3+/Am0 is −2.08±0.01 V. == Chemical properties == Americium readily reacts with oxygen and dissolves well in acids. The most common oxidation state for americium is +3, in which americium compounds are rather stable against oxidation and reduction. In this sense, americium is chemically similar to most lanthanides. The trivalent americium forms insoluble fluoride, oxalate, iodate, hydroxide, phosphate and other salts. Other oxidation states have been observed between +2 and +7, which is the widest range among the actinide elements. Their color in aqueous solutions varies as follows: Am3+ (colorless to yellow-reddish), Am4+ (yellow-reddish), AmVO+2; (yellow), AmVIO2+2 (brown) and AmVIIO5−6 (dark green). All oxidation states have their characteristic optical absorption spectra, with a few sharp peaks in the visible and mid-infrared regions, and the position and intensity of these peaks can be converted into the concentrations of the corresponding oxidation states. For example, Am(III) has two sharp peaks at 504 and 811 nm, Am(V) at 514 and 715 nm, and Am(VI) at 666 and 992 nm.Americium compounds with oxidation state +4 and higher are strong oxidizing agents, comparable in strength to the permanganate ion (MnO−4) in acidic solutions. Whereas the Am4+ ions are unstable in solutions and readily convert to Am3+, the +4 oxidation state occurs well in solids, such as americium dioxide (AmO2) and americium(IV) fluoride (AmF4). All pentavalent and hexavalent americium compounds are complex salts such as KAmO2F2, Li3AmO4 and Li6AmO6, Ba3AmO6, AmO2F2. These high oxidation states Am(IV), Am(V) and Am(VI) can be prepared from Am(III) by oxidation with ammonium persulfate in dilute nitric acid, with silver(I) oxide in perchloric acid, or with ozone or sodium persulfate in sodium carbonate solutions. The pentavalent oxidation state of americium was first observed in 1951. It is present in aqueous solution in the form of AmO+2 ions (acidic) or AmO−3 ions (alkaline) which are however unstable and subject to several rapid disproportionation reactions: 3 AmO 2 + + 4 H + ⟶ 2 AmO 2 2 + + Am 3 + + 2 H 2 O {\displaystyle {\ce {3AmO2+ + 4H+ -> 2AmO2^2+ + Am^3+ + 2H2O}}} 2 Am V ⟶ Am VI + Am IV {\displaystyle {\ce {2Am^{V}-> Am^{VI}{}+ Am^{IV}}}} == Chemical compounds == === Oxygen compounds === Three americium oxides are known, with the oxidation states +2 (AmO), +3 (Am2O3) and +4 (AmO2). Americium(II) oxide was prepared in minute amounts and has not been characterized in details. Americium(III) oxide is a red-brown solid with a melting point of 2205 °C. Americium(IV) oxide is the main form of solid americium which is used in nearly all its applications. As most other actinide dioxides, it is a black solid with a cubic (fluorite) crystal structure.The oxalate of americium(III), vacuum dried at room temperature, has the chemical formula Am2(C2O4)3·7H2O. Upon heating in vacuum, it loses water at 240 °C and starts decomposing into AmO2 at 300 °C, the decomposition completes at about 470 °C. The initial oxalate dissolves in nitric acid with the maximum solubility of 0.25 g/L. === Halides === Halides of americium are known for the oxidation states +2, +3 and +4, where the +3 is most stable, especially in solutions. Reduction of Am(III) compounds with sodium amalgam yields Am(II) salts – the black halides AmCl2, AmBr2 and AmI2. They are very sensitive to oxygen and oxidize in water, releasing hydrogen and converting back to the Am(III) state. Specific lattice constants are: Orthorhombic AmCl2: a = 896.3±0.8 pm, b = 757.3±0.8 pm and c = 453.2±0.6 pm Tetragonal AmBr2: a = 1159.2±0.4 pm and c = 712.1±0.3 pm. They can also be prepared by reacting metallic americium with an appropriate mercury halide HgX2, where X = Cl, Br or I: Am + HgX 2 mercury halide → 400 − 500 ∘ C AmX 2 + Hg {\displaystyle {\ce {{Am}+{\underset {mercury\ halide}{HgX2}}->[{} \atop 400-500^{\circ }{\ce {C}}]{AmX2}+{Hg}}}} Americium(III) fluoride (AmF3) is poorly soluble and precipitates upon reaction of Am3+ and fluoride ions in weak acidic solutions: Am 3 + + 3 F − ⟶ AmF 3 ↓ {\displaystyle {\ce {Am^3+ + 3F^- -> AmF3(v)}}} The tetravalent americium(IV) fluoride (AmF4) is obtained by reacting solid americium(III) fluoride with molecular fluorine: 2 AmF 3 + F 2 ⟶ 2 AmF 4 {\displaystyle {\ce {2AmF3 + F2 -> 2AmF4}}} Another known form of solid tetravalent americium chloride is KAmF5. Tetravalent americium has also been observed in the aqueous phase. For this purpose, black Am(OH)4 was dissolved in 15-M NH4F with the americium concentration of 0.01 M. The resulting reddish solution had a characteristic optical absorption spectrum which is similar to that of AmF4 but differed from other oxidation states of americium. Heating the Am(IV) solution to 90 °C did not result in its disproportionation or reduction, however a slow reduction was observed to Am(III) and assigned to self-irradiation of americium by alpha particles.Most americium(III) halides form hexagonal crystals with slight variation of the color and exact structure between the halogens. So, chloride (AmCl3) is reddish and has a structure isotypic to uranium(III) chloride (space group P63/m) and the melting point of 715 °C. The fluoride is isotypic to LaF3 (space group P63/mmc) and the iodide to BiI3 (space group R3). The bromide is an exception with the orthorhombic PuBr3-type structure and space group Cmcm. Crystals of americium hexahydrate (AmCl3·6H2O) can be prepared by dissolving americium dioxide in hydrochloric acid and evaporating the liquid. Those crystals are hygroscopic and have yellow-reddish color and a monoclinic crystal structure.Oxyhalides of americium in the form AmVIO2X2, AmVO2X, AmIVOX2 and AmIIIOX can be obtained by reacting the corresponding americium halide with oxygen or Sb2O3, and AmOCl can also be produced by vapor phase hydrolysis: AmCl 3 + H 2 O ⟶ AmOCl + 2 HCl {\displaystyle {\ce {AmCl3 + H2O -> AmOCl + 2HCl}}} === Chalcogenides and pnictides === The known chalcogenides of americium include the sulfide AmS2, selenides AmSe2 and Am3Se4, and tellurides Am2Te3 and AmTe2. The pnictides of americium (243Am) of the AmX type are known for the elements phosphorus, arsenic, antimony and bismuth. They crystallize in the rock-salt lattice. === Silicides and borides === Americium monosilicide (AmSi) and "disilicide" (nominally AmSix with: 1.87 < x < 2.0) were obtained by reduction of americium(III) fluoride with elementary silicon in vacuum at 1050 °C (AmSi) and 1150−1200 °C (AmSix). AmSi is a black solid isomorphic with LaSi, it has an orthorhombic crystal symmetry. AmSix has a bright silvery lustre and a tetragonal crystal lattice (space group I41/amd), it is isomorphic with PuSi2 and ThSi2. Borides of americium include AmB4 and AmB6. The tetraboride can be obtained by heating an oxide or halide of americium with magnesium diboride in vacuum or inert atmosphere. === Organoamericium compounds === Analogous to uranocene, americium forms the organometallic compound amerocene with two cyclooctatetraene ligands, with the chemical formula (η8-C8H8)2Am. It also makes the trigonal tricyclopentadienylamericium [(η5-C5H5)3Am)] complex with three cyclopentadienyl rings surrounding one atom of americium.Formation of the complexes of the type Am(n-C3H7-BTP)3, where BTP stands for 2,6-di(1,2,4-triazin-3-yl)pyridine, in solutions containing n-C3H7-BTP and Am3+ ions has been confirmed by EXAFS. Some of these BTP-type complexes selectively interact with americium and therefore are useful in its selective separation from lanthanides and another actinides. == Biological aspects == Americium is an artificial element of recent origin, and thus does not have a biological requirement. It is harmful to life. It has been proposed to use bacteria for removal of americium and other heavy metals from rivers and streams. Thus, Enterobacteriaceae of the genus Citrobacter precipitate americium ions from aqueous solutions, binding them into a metal-phosphate complex at their cell walls. Several studies have been reported on the biosorption and bioaccumulation of americium by bacteria and fungi. == Fission == The isotope 242mAm (half-life 141 years) has the largest cross sections for absorption of thermal neutrons (5,700 barns), that results in a small critical mass for a sustained nuclear chain reaction. The critical mass for a bare 242mAm sphere is about 9–14 kg (the uncertainty results from insufficient knowledge of its material properties). It can be lowered to 3–5 kg with a metal reflector and should become even smaller with a water reflector. Such small critical mass is favorable for portable nuclear weapons, but those based on 242mAm are not known yet, probably because of its scarcity and high price. The critical masses of two other readily available isotopes, 241Am and 243Am, are relatively high – 57.6 to 75.6 kg for 241Am and 209 kg for 243Am. Scarcity and high price yet hinder application of americium as a nuclear fuel in nuclear reactors.There are proposals of very compact 10-kW high-flux reactors using as little as 20 grams of 242mAm. Such low-power reactors would be relatively safe to use as neutron sources for radiation therapy in hospitals. == Isotopes == About 19 isotopes and 8 nuclear isomers are known for americium. There are two long-lived alpha-emitters, 241Am and 243Am with half-lives of 432.2 and 7,370 years, respectively, and the nuclear isomer 242m1Am has a long half-life of 141 years. The half-lives of other isotopes and isomers range from 0.64 microseconds for 245m1Am to 50.8 hours for 240Am. As with most other actinides, the isotopes of americium with odd number of neutrons have relatively high rate of nuclear fission and low critical mass.Americium-241 decays to 237Np emitting alpha particles of 5 different energies, mostly at 5.486 MeV (85.2%) and 5.443 MeV (12.8%). Because many of the resulting states are metastable, they also emit gamma rays with the discrete energies between 26.3 and 158.5 keV.Americium-242 is a short-lived isotope with a half-life of 16.02 h. It mostly (82.7%) converts by β-decay to 242Cm, but also by electron capture to 242Pu (17.3%). Both 242Cm and 242Pu transform via nearly the same decay chain through 238Pu down to 234U. Nearly all (99.541%) of 242m1Am decays by internal conversion to 242Am and the remaining 0.459% by α-decay to 238Np. The latter subsequently decays to 238Pu and then to 234U.Americium-243 transforms by α-emission into 239Np, which converts by β-decay to 239Pu, and the 239Pu changes into 235U by emitting an α-particle. == Applications == === Ionization-type smoke detector === Americium is used in the most common type of household smoke detector, which uses 241Am in the form of americium dioxide as its source of ionizing radiation. This isotope is preferred over 226Ra because it emits 5 times more alpha particles and relatively little harmful gamma radiation. Element collector Theodore Gray mentions in his book The Elements: A Visual Exploration of Every Known Atom in the Universe: You might think that a synthetic radioactive element that follows plutonium (94)—and has a significantly shorter half-life—would be some kind of superbomb material, available only to scientists in secret laboratories. Perhaps a mad scientist is studying americium in a lair somewhere, but if you want some yourself you can simply walk into any neighborhood hardware store, supermarket, or Wal-Mart and buy some, no questions asked. The reason is not that americium is fundamentally less dangerous than the elements around it. In fact, the commonly available isotope, 241Am, is significantly more radioactive than weapons-grade plutonium, and at least as toxic. No, the difference is simply that there is a useful application for americium that requires only a very tiny amount, and for which a company was prepared to go through the effort required to carve out and get a regulatory exception. The amount of americium in a typical new smoke detector is 1 microcurie (37 kBq) or 0.29 microgram. This amount declines slowly as the americium decays into neptunium-237, a different transuranic element with a much longer half-life (about 2.14 million years). With its half-life of 432.2 years, the americium in a smoke detector includes about 3% neptunium after 19 years, and about 5% after 32 years. The radiation passes through an ionization chamber, an air-filled space between two electrodes, and permits a small, constant current between the electrodes. Any smoke that enters the chamber absorbs the alpha particles, which reduces the ionization and affects this current, triggering the alarm. Compared to the alternative optical smoke detector, the ionization smoke detector is cheaper and can detect particles which are too small to produce significant light scattering; however, it is more prone to false alarms. === Radionuclide === As 241Am has a roughly similar half-life to 238Pu (432.2 years vs. 87 years), it has been proposed as an active element of radioisotope thermoelectric generators, for example in spacecraft. Although americium produces less heat and electricity – the power yield is 114.7 mW/g for 241Am and 6.31 mW/g for 243Am (cf. 390 mW/g for 238Pu) – and its radiation poses more threat to humans owing to neutron emission, the European Space Agency is considering using americium for its space probes.Another proposed space-related application of americium is a fuel for space ships with nuclear propulsion. It relies on the very high rate of nuclear fission of 242mAm, which can be maintained even in a micrometer-thick foil. Small thickness avoids the problem of self-absorption of emitted radiation. This problem is pertinent to uranium or plutonium rods, in which only surface layers provide alpha-particles. The fission products of 242mAm can either directly propel the spaceship or they can heat a thrusting gas. They can also transfer their energy to a fluid and generate electricity through a magnetohydrodynamic generator.One more proposal which utilizes the high nuclear fission rate of 242mAm is a nuclear battery. Its design relies not on the energy of the emitted by americium alpha particles, but on their charge, that is the americium acts as the self-sustaining "cathode". A single 3.2 kg 242mAm charge of such battery could provide about 140 kW of power over a period of 80 days. Even with all the potential benefits, the current applications of 242mAm are as yet hindered by the scarcity and high price of this particular nuclear isomer. === Neutron source === The oxide of 241Am pressed with beryllium is an efficient neutron source. Here americium acts as the alpha source, and beryllium produces neutrons owing to its large cross-section for the (α,n) nuclear reaction: Am 95 241 ⟶ Np 93 237 + He 2 4 + γ {\displaystyle {\ce {^{241}_{95}Am -> ^{237}_{93}Np + ^{4}_{2}He + \gamma}}} Be 4 9 + He 2 4 ⟶ C 6 12 + n 0 1 + γ {\displaystyle {\ce {^{9}_{4}Be + ^{4}_{2}He -> ^{12}_{6}C + ^{1}_{0}n + \gamma}}} The most widespread use of 241AmBe neutron sources is a neutron probe – a device used to measure the quantity of water present in soil, as well as moisture/density for quality control in highway construction. 241Am neutron sources are also used in well logging applications, as well as in neutron radiography, tomography and other radiochemical investigations. === Production of other elements === Americium is a starting material for the production of other transuranic elements and transactinides – for example, 82.7% of 242Am decays to 242Cm and 17.3% to 242Pu. In the nuclear reactor, 242Am is also up-converted by neutron capture to 243Am and 244Am, which transforms by β-decay to 244Cm: Am 95 243 → ( n , γ ) Am 95 244 → 10.1 h β − Cm 96 244 {\displaystyle {\ce {^{243}_{95}Am ->[{\ce {(n,\gamma)}}] ^{244}_{95}Am ->[\beta^-][10.1 \ {\ce {h}}] ^{244}_{96}Cm}}} Irradiation of 241Am by 12C or 22Ne ions yields the isotopes 247Es (einsteinium) or 260Db (dubnium), respectively. Furthermore, the element berkelium (243Bk isotope) had been first intentionally produced and identified by bombarding 241Am with alpha particles, in 1949, by the same Berkeley group, using the same 60-inch cyclotron. Similarly, nobelium was produced at the Joint Institute for Nuclear Research, Dubna, Russia, in 1965 in several reactions, one of which included irradiation of 243Am with 15N ions. Besides, one of the synthesis reactions for lawrencium, discovered by scientists at Berkeley and Dubna, included bombardment of 243Am with 18O. === Spectrometer === Americium-241 has been used as a portable source of both gamma rays and alpha particles for a number of medical and industrial uses. The 59.5409 keV gamma ray emissions from 241Am in such sources can be used for indirect analysis of materials in radiography and X-ray fluorescence spectroscopy, as well as for quality control in fixed nuclear density gauges and nuclear densometers. For example, the element has been employed to gauge glass thickness to help create flat glass. Americium-241 is also suitable for calibration of gamma-ray spectrometers in the low-energy range, since its spectrum consists of nearly a single peak and negligible Compton continuum (at least three orders of magnitude lower intensity). Americium-241 gamma rays were also used to provide passive diagnosis of thyroid function. This medical application is however obsolete. == Health concerns == As a highly radioactive element, americium and its compounds must be handled only in an appropriate laboratory under special arrangements. Although most americium isotopes predominantly emit alpha particles which can be blocked by thin layers of common materials, many of the daughter products emit gamma-rays and neutrons which have a long penetration depth.If consumed, most of the americium is excreted within a few days, with only 0.05% absorbed in the blood, of which roughly 45% goes to the liver and 45% to the bones, and the remaining 10% is excreted. The uptake to the liver depends on the individual and increases with age. In the bones, americium is first deposited over cortical and trabecular surfaces and slowly redistributes over the bone with time. The biological half-life of 241Am is 50 years in the bones and 20 years in the liver, whereas in the gonads (testicles and ovaries) it remains permanently; in all these organs, americium promotes formation of cancer cells as a result of its radioactivity.Americium often enters landfills from discarded smoke detectors. The rules associated with the disposal of smoke detectors are relaxed in most jurisdictions. In 1994, 17-year-old David Hahn extracted the americium from about 100 smoke detectors in an attempt to build a breeder nuclear reactor. There have been a few cases of exposure to americium, the worst case being that of chemical operations technician Harold McCluskey, who at the age of 64 was exposed to 500 times the occupational standard for americium-241 as a result of an explosion in his lab. McCluskey died at the age of 75 of unrelated pre-existing disease. == See also == Actinides in the environment Category:Americium compounds == Notes == == References == == Bibliography == Greenwood, Norman N.; Earnshaw, Alan (1997).

### Instruction: retrieve labels for this: Astatine is a radioactive chemical element with symbol At and atomic number 85. It is the rarest naturally occurring element in the Earth's crust, occurring only as the decay product of various heavier elements. All of astatine's isotopes are short-lived; the most stable is astatine-210, with a half-life of 8.1 hours. A sample of the pure element has never been assembled, because any macroscopic specimen would be immediately vaporized by the heat of its own radioactivity. The bulk properties of astatine are not known with any certainty. Many of them have been estimated based on the element's position on the periodic table as a heavier analog of iodine, and a member of the halogens (the group of elements including fluorine, chlorine, bromine, and iodine). Astatine is likely to have a dark or lustrous appearance and may be a semiconductor or possibly a metal; it probably has a higher melting point than that of iodine. Chemically, several anionic species of astatine are known and most of its compounds resemble those of iodine. It also shows some metallic behavior, including being able to form a stable monatomic cation in aqueous solution (unlike the lighter halogens). The first synthesis of the element was in 1940 by Dale R. Corson, Kenneth Ross MacKenzie, and Emilio G. Segrè at the University of California, Berkeley, who named it from the Greek astatos (ἄστατος), meaning "unstable". Four isotopes of astatine were subsequently found to be naturally occurring, although much less than one gram is present at any given time in the Earth's crust. Neither the most stable isotope astatine-210, nor the medically useful astatine-211, occur naturally; they can only be produced synthetically, usually by bombarding bismuth-209 with alpha particles. == Characteristics == Astatine is an extremely radioactive element; all its isotopes have short half-lives of 8.1 hours or less, decaying into other astatine isotopes, bismuth, polonium or radon. Most of its isotopes are very unstable with half-lives of one second or less. Of the first 101 elements in the periodic table, only francium is less stable, and all the astatine isotopes more stable than francium are in any case synthetic and do not occur in nature.The bulk properties of astatine are not known with any certainty. Research is limited by its short half-life, which prevents the creation of weighable quantities. A visible piece of astatine would immediately vaporize itself because of the heat generated by its intense radioactivity. It remains to be seen if, with sufficient cooling, a macroscopic quantity of astatine could be deposited as a thin film. Astatine is usually classified as either a nonmetal or a metalloid; metal formation has also been predicted. === Physical === Most of the physical properties of astatine have been estimated (by interpolation or extrapolation), using theoretically or empirically derived methods. For example, halogens get darker with increasing atomic weight – fluorine is nearly colorless, chlorine is yellow-green, bromine is red-brown, and iodine is dark gray/violet. Astatine is sometimes described as probably being a black solid (assuming it follows this trend), or as having a metallic appearance (if it is a metalloid or a metal). The melting and boiling points of astatine are also expected to follow the trend seen in the halogen series, increasing with atomic number. On this basis they are estimated to be 575 and 610 K (302 and 337 °C; 575 and 638 °F), respectively. Some experimental evidence suggests astatine may have lower melting and boiling points than those implied by the halogen trend. Astatine sublimes less readily than does iodine, having a lower vapor pressure. Even so, half of a given quantity of astatine will vaporize in approximately an hour if put on a clean glass surface at room temperature. The absorption spectrum of astatine in the middle ultraviolet region has lines at 224.401 and 216.225 nm, suggestive of 6p to 7s transitions.The structure of solid astatine is unknown. As an analogue of iodine it may have an orthorhombic crystalline structure composed of diatomic astatine molecules, and be a semiconductor (with a band gap of 0.7 eV). Alternatively, if condensed astatine forms a metallic phase, as has been predicted, it may have a monatomic face-centered cubic structure; in this structure it may well be a superconductor, like the similar high-pressure phase of iodine. Evidence for (or against) the existence of diatomic astatine (At2) is sparse and inconclusive. Some sources state that it does not exist, or at least has never been observed, while other sources assert or imply its existence. Despite this controversy, many properties of diatomic astatine have been predicted; for example, its bond length would be 300±10 pm, dissociation energy 83.7±12.5 kJ/mol, and heat of vaporization (∆Hvap) 54.39 kJ/mol. The latter figure means that astatine may (at least) be metallic in the liquid state on the basis that elements with a heat of vaporization greater than ~42 kJ/mol are metallic when liquid; diatomic iodine, with a value of 41.71 kJ/mol, falls just short of the threshold figure. === Chemical === The chemistry of astatine is "clouded by the extremely low concentrations at which astatine experiments have been conducted, and the possibility of reactions with impurities, walls and filters, or radioactivity by-products, and other unwanted nano-scale interactions." Many of its apparent chemical properties have been observed using tracer studies on extremely dilute astatine solutions, typically less than 10−10 mol·L−1. Some properties – such as anion formation – align with other halogens. Astatine has some metallic characteristics as well, such as plating onto a cathode, coprecipitating with metal sulfides in hydrochloric acid, and forming a stable monatomic cation in aqueous solution. It forms complexes with EDTA, a metal chelating agent, and is capable of acting as a metal in antibody radiolabeling; in some respects astatine in the +1 state is akin to silver in the same state. Most of the organic chemistry of astatine is, however, analogous to that of iodine.Astatine has an electronegativity of 2.2 on the revised Pauling scale – lower than that of iodine (2.66) and the same as hydrogen. In hydrogen astatide (HAt) the negative charge is predicted to be on the hydrogen atom, implying that this compound could be referred to as astatine hydride according to certain nomenclatures, That would be consistent with the electronegativity of astatine on the Allred–Rochow scale (1.9) being less than that of hydrogen (2.2). However, official IUPAC stoichiometric nomenclature is based on an idealized convention of determining the relative electronegativities of the elements by the mere virtue of their position within the periodic table. According to this convention, astatine is handled as though it is more electronegative than hydrogen, irrespective of its true electronegativity. The electron affinity of astatine is predicted to be reduced by one-third because of spin–orbit interactions. == Compounds == Less reactive than iodine, astatine is the least reactive of the halogens, although its compounds have been synthesized in microscopic amounts and studied as intensively as possible before their radioactive disintegration. The reactions involved have been typically tested with dilute solutions of astatine mixed with larger amounts of iodine. Acting as a carrier, the iodine ensures there is sufficient material for laboratory techniques (such as filtration and precipitation) to work. Like iodine, astatine has been shown to adopt odd-numbered oxidation states ranging from −1 to +7. Only a few compounds with metals have been reported, in the form of astatides of sodium, palladium, silver, thallium, and lead. Some characteristic properties of silver and sodium astatide, and the other hypothetical alkali and alkaline earth astatides, have been estimated by extrapolation from other metal halides. The formation of an astatine compound with hydrogen – usually referred to as hydrogen astatide – was noted by the pioneers of astatine chemistry. As mentioned, there are grounds for instead referring to this compound as astatine hydride. It is easily oxidized; acidification by dilute nitric acid gives the At0 or At+ forms, and the subsequent addition of silver(I) may only partially, at best, precipitate astatine as silver(I) astatide (AgAt). Iodine, in contrast, is not oxidized, and precipitates readily as silver(I) iodide.Astatine is known to bind to boron, carbon, and nitrogen. Various boron cage compounds have been prepared with At–B bonds, these being more stable than At–C bonds. Astatine can replace a hydrogen atom in benzene to form astatobenzene C6H5At; this may be oxidized to C6H5AtCl2 by chlorine. By treating this compound with an alkaline solution of hypochlorite, C6H5AtO2 can be produced. In the molecules dipyridine-astatine(I) perchlorate [At(C5H5N)2] [ClO4] and the analogous nitrate, the astatine atom is bonded to each nitrogen atom in the two pyridine rings.With oxygen, there is evidence of the species AtO− and AtO+ in aqueous solution, formed by the reaction of astatine with an oxidant such as elemental bromine or (in the last case) by sodium persulfate in a solution of perchloric acid. The species previously thought to be AtO−2 has since been determined to be AtO(OH)−2, a hydrolysis product of AtO+ (another such hydrolysis product being AtOOH). The well characterized AtO−3 anion can be obtained by, for example, the oxidation of astatine with potassium hypochlorite in a solution of potassium hydroxide. Preparation of lanthanum triastatate La(AtO3)3, following the oxidation of astatine by a hot Na2S2O8 solution, has been reported. Further oxidation of AtO−3, such as by xenon difluoride (in a hot alkaline solution) or periodate (in a neutral or alkaline solution), yields the perastatate ion AtO−4; this is only stable in neutral or alkaline solutions. Astatine is also thought to be capable of forming cations in salts with oxyanions such as iodate or dichromate; this is based on the observation that, in acidic solutions, monovalent or intermediate positive states of astatine coprecipitate with the insoluble salts of metal cations such as silver(I) iodate or thallium(I) dichromate.Astatine may form bonds to the other chalcogens; these include S7At+ and At(CSN)−2 with sulfur, a coordination selenourea compound with selenium, and an astatine–tellurium colloid with tellurium. Astatine is known to react with its lighter homologs iodine, bromine, and chlorine in the vapor state; these reactions produce diatomic interhalogen compounds with formulas AtI, AtBr, and AtCl. The first two compounds may also be produced in water – astatine reacts with iodine/iodide solution to form AtI, whereas AtBr requires (aside from astatine) an iodine/iodine monobromide/bromide solution. The excess of iodides or bromides may lead to AtBr−2 and AtI−2 ions, or in a chloride solution, they may produce species like AtCl−2 or AtBrCl− via equilibrium reactions with the chlorides. Oxidation of the element with dichromate (in nitric acid solution) showed that adding chloride turned the astatine into a molecule likely to be either AtCl or AtOCl. Similarly, AtOCl−2 or AtCl−2 may be produced. The polyhalides PdAtI2, CsAtI2, TlAtI2, and PbAtI are known or presumed to have been precipitated. In a plasma ion source mass spectrometer, the ions [AtI]+, [AtBr]+, and [AtCl]+ have been formed by introducing lighter halogen vapors into a helium-filled cell containing astatine, supporting the existence of stable neutral molecules in the plasma ion state. No astatine fluorides have been discovered yet. Their absence has been speculatively attributed to the extreme reactivity of such compounds, including the reaction of an initially formed fluoride with the walls of the glass container to form a non-volatile product. Thus, although the synthesis of an astatine fluoride is thought to be possible, it may require a liquid halogen fluoride solvent, as has already been used for the characterization of radon fluoride. == History == In 1869, when Dmitri Mendeleev published his periodic table, the space under iodine was empty; after Niels Bohr established the physical basis of the classification of chemical elements, it was suggested that the fifth halogen belonged there. Before its officially recognized discovery, it was called "eka-iodine" (from Sanskrit eka – "one") to imply it was one space under iodine (in the same manner as eka-silicon, eka-boron, and others). Scientists tried to find it in nature; given its extreme rarity, these attempts resulted in several false discoveries.The first claimed discovery of eka-iodine was made by Fred Allison and his associates at the Alabama Polytechnic Institute (now Auburn University) in 1931. The discoverers named element 85 "alabamine", and assigned it the symbol Ab, designations that were used for a few years. In 1934, H. G. MacPherson of University of California, Berkeley disproved Allison's method and the validity of his discovery. There was another claim in 1937, by the chemist Rajendralal De. Working in Dacca in British India (now Dhaka in Bangladesh), he chose the name "dakin" for element 85, which he claimed to have isolated as the thorium series equivalent of radium F (polonium-210) in the radium series. The properties he reported for dakin do not correspond to those of astatine; moreover, astatine is not found in the thorium series, and the true identity of dakin is not known.In 1936, a team of Romanian physicist Horia Hulubei and French physicist Yvette Cauchois claimed to have discovered element 85 via X-ray analysis. In 1939 they published another paper which supported and extended previous data. In 1944, Hulubei published a summary of data he had obtained up to that time, claiming it was supported by the work of other researchers. He chose the name "dor", presumably from the Romanian for "longing" [for peace], as World War II had started five years earlier. As Hulubei was writing in French, a language which does not accommodate the "ine" suffix, dor would likely have been rendered in English as "dorine", had it been adopted. In 1947, Hulubei's claim was effectively rejected by the Austrian chemist Friedrich Paneth, who would later chair the IUPAC committee responsible for recognition of new elements. Even though Hulubei's samples did contain astatine, his means to detect it were too weak, by current standards, to enable correct identification. He had also been involved in an earlier false claim as to the discovery of element 87 (francium) and this is thought to have caused other researchers to downplay his work. In 1940, the Swiss chemist Walter Minder announced the discovery of element 85 as the beta decay product of radium A (polonium-218), choosing the name "helvetium" (from Helvetia, the Latin name of Switzerland). Karlik and Bernert were unsuccessful in reproducing his experiments, and subsequently attributed Minder's results to contamination of his radon stream (radon-222 is the parent isotope of polonium-218). In 1942, Minder, in collaboration with the English scientist Alice Leigh-Smith, announced the discovery of another isotope of element 85, presumed to be the product of thorium A (polonium-216) beta decay. They named this substance "anglo-helvetium", but Karlik and Bernert were again unable to reproduce these results.Later in 1940, Dale R. Corson, Kenneth Ross MacKenzie, and Emilio Segrè isolated the element at the University of California, Berkeley. Instead of searching for the element in nature, the scientists created it by bombarding bismuth-209 with alpha particles in a cyclotron (particle accelerator) to produce, after emission of two neutrons, astatine-211. The discoverers, however, did not immediately suggest a name for the element. The reason for this was that at the time, an element created synthetically in "invisible quantities" that had not yet discovered in nature was not seen as a completely valid one; in addition, chemists were reluctant to recognize radioactive isotopes as legitimately as stable ones. In 1943, astatine was found as a product of two naturally occurring decay chains by Berta Karlik and Traude Bernert, first in the so-called uranium series, and then in the actinium series. (Since then, astatine has been determined in a third decay chain, the neptunium series.) Friedrich Paneth in 1946 called to finally recognize synthetic elements, quoting, among other reasons, recent confirmation of their natural occurrence, and proposed that the discoverers of the newly discovered unnamed elements name these elements. In early 1947, Nature published the discoverers' suggestions; a letter from Corson, MacKenzie, and Segrè suggested the name "astatine" coming from the Greek astatos (αστατος) meaning "unstable", because of its propensity for radioactive decay, with the ending "-ine", found in the names of the four previously discovered halogens. The name was also chosen to continue the tradition of the four stable halogens, where the name referred to a property of the element.Corson and his colleagues classified astatine as a metal on the basis of its analytical chemistry. Subsequent investigators reported iodine-like, cationic, or amphoteric behavior. In a 2003 retrospective, Corson wrote that "some of the properties [of astatine] are similar to iodine … it also exhibits metallic properties, more like its metallic neighbors Po and Bi." == Isotopes == There are 39 known isotopes of astatine, with atomic masses (mass numbers) of 191–229. Theoretical modeling suggests that 37 more isotopes could exist. No stable or long-lived astatine isotope has been observed, nor is one expected to exist.Astatine's alpha decay energies follow the same trend as for other heavy elements. Lighter astatine isotopes have quite high energies of alpha decay, which become lower as the nuclei become heavier. Astatine-211 has a significantly higher energy than the previous isotope, because it has a nucleus with 126 neutrons, and 126 is a magic number corresponding to a filled neutron shell. Despite having a similar half-life to the previous isotope (8.1 hours for astatine-210 and 7.2 hours for astatine-211), the alpha decay probability is much higher for the latter: 41.81% against only 0.18%. The two following isotopes release even more energy, with astatine-213 releasing the most energy. For this reason, it is the shortest-lived astatine isotope. Even though heavier astatine isotopes release less energy, no long-lived astatine isotope exists, because of the increasing role of beta decay (electron emission). This decay mode is especially important for astatine; as early as 1950 it was postulated that all isotopes of the element undergo beta decay. Beta decay modes have been found for all astatine isotopes except astatine-213, -214, -215, and -216m. Astatine-210 and lighter isotopes exhibit beta plus decay (positron emission), astatine-216 and heavier isotopes exhibit beta (minus) decay, and astatine-212 decays via both modes, while astatine-211 undergoes electron capture.The most stable isotope is astatine-210, which has a half-life of 8.1 hours. The primary decay mode is beta plus, to the relatively long-lived (in comparison to astatine isotopes) alpha emitter polonium-210. In total, only five isotopes have half-lives exceeding one hour (astatine-207 to -211). The least stable ground state isotope is astatine-213, with a half-life of 125 nanoseconds. It undergoes alpha decay to the extremely long-lived bismuth-209.Astatine has 24 known nuclear isomers, which are nuclei with one or more nucleons (protons or neutrons) in an excited state. A nuclear isomer may also be called a "meta-state", meaning the system has more internal energy than the "ground state" (the state with the lowest possible internal energy), making the former likely to decay into the latter. There may be more than one isomer for each isotope. The most stable of these nuclear isomers is astatine-202m1, which has a half-life of about 3 minutes, longer than those of all the ground states bar those of isotopes 203–211 and 220. The least stable is astatine-214m1; its half-life of 265 nanoseconds is shorter than those of all ground states except that of astatine-213. == Natural occurrence == Astatine is the rarest naturally occurring element. The total amount of astatine in the Earth's crust (quoted mass 2.36 × 1025 grams) is estimated to be less than one gram at any given time.Any astatine present at the formation of the Earth has long since disappeared; the four naturally occurring isotopes (astatine-215, -217, -218 and -219) are instead continuously produced as a result of the decay of radioactive thorium and uranium ores, and trace quantities of neptunium-237. The landmass of North and South America combined, to a depth of 16 kilometers (10 miles), contains only about one trillion astatine-215 atoms at any given time (around 3.5 × 10−10 grams). Astatine-217 is produced via the radioactive decay of neptunium-237. Primordial remnants of the latter isotope—due to its relatively short half-life of 2.14 million years—are no longer present on Earth. However, trace amounts occur naturally as a product of transmutation reactions in uranium ores. Astatine-218 was the first astatine isotope discovered in nature. Astatine-219, with a half-life of 56 seconds, is the longest lived of the naturally occurring isotopes.Isotopes of astatine are sometimes not listed as naturally occurring because of misconceptions that there are no such isotopes, or discrepancies in the literature. Astatine-216 has been counted as a naturally occurring isotope but reports of its observation (which were described as doubtful) have not been confirmed. == Synthesis == === Formation === Astatine was first produced by bombarding bismuth-209 with energetic alpha particles, and this is still the major route used to create the relatively long-lived isotopes astatine-209 through astatine-211. Astatine is only produced in minuscule quantities, with modern techniques allowing production runs of up to 6.6 giga becquerels (about 86 nanograms or 2.47 × 1014 atoms). Synthesis of greater quantities of astatine using this method is constrained by the limited availability of suitable cyclotrons and the prospect of melting the target. Solvent radiolysis due to the cumulative effect of astatine decay is a related problem. With cryogenic technology, microgram quantities of astatine might be able to be generated via proton irradiation of thorium or uranium to yield radon-211, in turn decaying to astatine-211. Contamination with astatine-210 is expected to be a drawback of this method.The most important isotope is astatine-211, the only one in commercial use. To produce the bismuth target, the metal is sputtered onto a gold, copper, or aluminium surface at 50 to 100 milligrams per square centimeter. Bismuth oxide can be used instead; this is forcibly fused with a copper plate. The target is kept under a chemically neutral nitrogen atmosphere, and is cooled with water to prevent premature astatine vaporization. In a particle accelerator, such as a cyclotron, alpha particles are collided with the bismuth. Even though only one bismuth isotope is used (bismuth-209), the reaction may occur in three possible ways, producing astatine-209, astatine-210, or astatine-211. In order to eliminate undesired nuclides, the maximum energy of the particle accelerator is set to a value (optimally 29.17 MeV) above that for the reaction producing astatine-211 (to produce the desired isotope) and below the one producing astatine-210 (to avoid producing other astatine isotopes). === Separation methods === Since astatine is the main product of the synthesis, after its formation it must only be separated from the target and any significant contaminants. Several methods are available, "but they generally follow one of two approaches—dry distillation or [wet] acid treatment of the target followed by solvent extraction." The methods summarized below are modern adaptations of older procedures, as reviewed by Kugler and Keller. Pre-1985 techniques more often addressed the elimination of co-produced toxic polonium; this requirement is now mitigated by capping the energy of the cyclotron irradiation beam. ==== Dry ==== The astatine-containing cyclotron target is heated to a temperature of around 650 °C. The astatine volatilizes and is condensed in (typically) a cold trap. Higher temperatures of up to around 850 °C may increase the yield, at the risk of bismuth contamination from concurrent volatilization. Redistilling the condensate may be required to minimize the presence of bismuth (as bismuth can interfere with astatine labeling reactions). The astatine is recovered from the trap using one or more low concentration solvents such as sodium hydroxide, methanol or chloroform. Astatine yields of up to around 80% may be achieved. Dry separation is the method most commonly used to produce a chemically useful form of astatine. ==== Wet ==== The bismuth (or sometimes bismuth trioxide) target is dissolved in, for example, concentrated nitric or perchloric acid. Astatine is extracted using an organic solvent such as butyl or isopropyl ether, or thiosemicarbazide. A separation yield of 93% using nitric acid has been reported, falling to 72% by the time purification procedures were completed (distillation of nitric acid, purging residual nitrogen oxides, and redissolving bismuth nitrate to enable liquid–liquid extraction). Wet methods involve "multiple radioactivity handling steps" and are not well suited for isolating larger quantities of astatine. They can enable the production of astatine in a specific oxidation state and may have greater applicability in experimental radiochemistry. == Uses and precautions == Newly formed astatine-211 is the subject of ongoing research in nuclear medicine. It must be used quickly as it decays with a half-life of 7.2 hours; this is long enough to permit multistep labeling strategies. Astatine-211 has potential for targeted alpha particle radiotherapy, since it decays either via emission of an alpha particle (to bismuth-207), or via electron capture (to an extremely short-lived nuclide, polonium-211, which undergoes further alpha decay), very quickly reaching its stable granddaughter lead-207. Polonium X-rays emitted as a result of the electron capture branch, in the range of 77–92 keV, enable the tracking of astatine in animals and patients. Although astatine-210 has a slightly longer half-life, it is wholly unsuitable because it usually undergoes beta plus decay to the extremely toxic polonium-210.The principal medicinal difference between astatine-211 and iodine-131 (a radioactive iodine isotope also used in medicine) is that iodine-131 emits high-energy beta particles, and astatine does not. Beta particles have much greater penetrating power through tissues than do the much heavier alpha particles. An average alpha particle released by astatine-211 can travel up to 70 µm through surrounding tissues; an average-energy beta particle emitted by iodine-131 can travel nearly 30 times as far, to about 2 mm. The short half-life and limited penetrating power of alpha radiation through tissues offers advantages in situations where the "tumor burden is low and/or malignant cell populations are located in close proximity to essential normal tissues." Significant morbidity in cell culture models of human cancers has been achieved with from one to ten astatine-211 atoms bound per cell. Several obstacles have been encountered in the development of astatine-based radiopharmaceuticals for cancer treatment. World War II delayed research for close to a decade. Results of early experiments indicated that a cancer-selective carrier would need to be developed and it was not until the 1970s that monoclonal antibodies became available for this purpose. Unlike iodine, astatine shows a tendency to dehalogenate from molecular carriers such as these, particularly at sp3 carbon sites (less so from sp2 sites). Given the toxicity of astatine accumulated and retained in the body, this emphasized the need to ensure it remained attached to its host molecule. While astatine carriers that are slowly metabolized can be assessed for their efficacy, more rapidly metabolized carriers remain a significant obstacle to the evaluation of astatine in nuclear medicine. Mitigating the effects of astatine-induced radiolysis of labeling chemistry and carrier molecules is another area requiring further development. A practical application for astatine as a cancer treatment would potentially be suitable for a "staggering" number of patients; production of astatine in the quantities that would be required remains an issue.Animal studies show that astatine, similarly to iodine, although to a lesser extent, is preferentially concentrated in the thyroid gland. Unlike iodine, astatine also shows a tendency to be taken up by the lungs and spleen, possibly because of in-body oxidation of At– to At+. If administered in the form of a radiocolloid it tends to concentrate in the liver. Experiments in rats and monkeys suggest that astatine-211 causes much greater damage to the thyroid gland than does iodine-131, with repetitive injection of the nuclide resulting in necrosis and cell dysplasia within the gland. Early research suggested that injection of astatine into female rodents caused morphological changes in breast tissue; this conclusion remained controversial for many years. General agreement was later reached that this was likely caused by the effect of breast tissue irradiation combined with hormonal changes due to irradiation of the ovaries. Trace amounts of astatine can be handled safely in fume hoods if they are well-aerated; biological uptake of the element must be avoided. == See also == Radiation protection == Notes == == References == == Bibliography == Corson, D.

### Instruction: retrieve labels for this: An atom is the smallest constituent unit of ordinary matter that has the properties of a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small; typical sizes are around 100 picometers (a ten-billionth of a meter, in the short scale). Atoms are small enough that attempting to predict their behavior using classical physics – as if they were billiard balls, for example – gives noticeably incorrect predictions due to quantum effects. Through the development of physics, atomic models have incorporated quantum principles to better explain and predict this behavior. Every atom is composed of a nucleus and one or more electrons bound to the nucleus. The nucleus is made of one or more protons and typically a similar number of neutrons. Protons and neutrons are called nucleons. More than 99.94% of an atom's mass is in the nucleus. The protons have a positive electric charge, the electrons have a negative electric charge, and the neutrons have no electric charge. If the number of protons and electrons are equal, that atom is electrically neutral. If an atom has more or fewer electrons than protons, then it has an overall negative or positive charge, respectively, and it is called an ion. The electrons of an atom are attracted to the protons in an atomic nucleus by this electromagnetic force. The protons and neutrons in the nucleus are attracted to each other by a different force, the nuclear force, which is usually stronger than the electromagnetic force repelling the positively charged protons from one another. Under certain circumstances, the repelling electromagnetic force becomes stronger than the nuclear force, and nucleons can be ejected from the nucleus, leaving behind a different element: nuclear decay resulting in nuclear transmutation. The number of protons in the nucleus defines to what chemical element the atom belongs: for example, all copper atoms contain 29 protons. The number of neutrons defines the isotope of the element. The number of electrons influences the magnetic properties of an atom. Atoms can attach to one or more other atoms by chemical bonds to form chemical compounds such as molecules. The ability of atoms to associate and dissociate is responsible for most of the physical changes observed in nature and is the subject of the discipline of chemistry. == History of atomic theory == === Atoms in philosophy === The idea that matter is made up of discrete units is a very old idea, appearing in many ancient cultures such as Greece and India. The word "atom" was coined by the ancient Greek philosophers Leucippus and his pupil Democritus. However, these ideas were founded in philosophical and theological reasoning rather than evidence and experimentation. As a result, their views on what atoms look like and how they behave were incorrect. They also could not convince everybody, so atomism was but one of a number of competing theories on the nature of matter. It was not until the 19th century that the idea was embraced and refined by scientists, when the blossoming science of chemistry produced discoveries that only the concept of atoms could explain. === First evidence-based theory === In the early 1800s, John Dalton used the concept of atoms to explain why elements always react in ratios of small whole numbers (the law of multiple proportions). For instance, there are two types of tin oxide: one is 88.1% tin and 11.9% oxygen and the other is 78.7% tin and 21.3% oxygen (tin(II) oxide and tin dioxide respectively). This means that 100g of tin will combine either with 13.5g or 27g of oxygen. 13.5 and 27 form a ratio of 1:2, a ratio of small whole numbers. This common pattern in chemistry suggested to Dalton that elements react in whole number multiples of discrete units—in other words, atoms. In the case of tin oxides, one tin atom will combine with either one or two oxygen atoms.Dalton also believed atomic theory could explain why water absorbs different gases in different proportions. For example, he found that water absorbs carbon dioxide far better than it absorbs nitrogen. Dalton hypothesized this was due to the differences between the masses and configurations of the gases' respective particles, and carbon dioxide molecules (CO2) are heavier and larger than nitrogen molecules (N2). === Brownian motion === In 1827, botanist Robert Brown used a microscope to look at dust grains floating in water and discovered that they moved about erratically, a phenomenon that became known as "Brownian motion". This was thought to be caused by water molecules knocking the grains about. In 1905, Albert Einstein proved the reality of these molecules and their motions by producing the first Statistical physics analysis of Brownian motion. French physicist Jean Perrin used Einstein's work to experimentally determine the mass and dimensions of atoms, thereby conclusively verifying Dalton's atomic theory. === Discovery of the electron === The physicist J. J. Thomson measured the mass of cathode rays, showing they were made of particles, but were around 1800 times lighter than the lightest atom, hydrogen. Therefore, they were not atoms, but a new particle, the first subatomic particle to be discovered, which he originally called "corpuscle" but was later named electron, after particles postulated by George Johnstone Stoney in 1874. He also showed they were identical to particles given off by photoelectric and radioactive materials. It was quickly recognized that they are the particles that carry electric currents in metal wires, and carry the negative electric charge within atoms. Thomson was given the 1906 Nobel Prize in Physics for this work. Thus he overturned the belief that atoms are the indivisible, ultimate particles of matter. Thomson also incorrectly postulated that the low mass, negatively charged electrons were distributed throughout the atom in a uniform sea of positive charge. This became known as the plum pudding model. === Discovery of the nucleus === In 1909, Hans Geiger and Ernest Marsden, under the direction of Ernest Rutherford, bombarded a metal foil with alpha particles to observe how they scattered. They expected all the alpha particles to pass straight through with little deflection, because Thomson's model said that the charges in the atom are so diffuse that their electric fields could not affect the alpha particles much. However, Geiger and Marsden spotted alpha particles being deflected by angles greater than 90°, which was supposed to be impossible according to Thomson's model. To explain this, Rutherford proposed that the positive charge of the atom is concentrated in a tiny nucleus at the center of the atom. Rutherford compared his findings to one firing a 15-inch shell at a sheet of tissue paper and it coming back to hit the person who fired it. === Discovery of isotopes === While experimenting with the products of radioactive decay, in 1913 radiochemist Frederick Soddy discovered that there appeared to be more than one type of atom at each position on the periodic table. The term isotope was coined by Margaret Todd as a suitable name for different atoms that belong to the same element. J.J. Thomson created a technique for separating atom types through his work on ionized gases, which subsequently led to the discovery of stable isotopes. === Bohr model === In 1913 the physicist Niels Bohr proposed a model in which the electrons of an atom were assumed to orbit the nucleus but could only do so in a finite set of orbits, and could jump between these orbits only in discrete changes of energy corresponding to absorption or radiation of a photon. This quantization was used to explain why the electrons orbits are stable (given that normally, charges in acceleration, including circular motion, lose kinetic energy which is emitted as electromagnetic radiation, see synchrotron radiation) and why elements absorb and emit electromagnetic radiation in discrete spectra.Later in the same year Henry Moseley provided additional experimental evidence in favor of Niels Bohr's theory. These results refined Ernest Rutherford's and Antonius Van den Broek's model, which proposed that the atom contains in its nucleus a number of positive nuclear charges that is equal to its (atomic) number in the periodic table. Until these experiments, atomic number was not known to be a physical and experimental quantity. That it is equal to the atomic nuclear charge remains the accepted atomic model today. === Chemical bonding explained === Chemical bonds between atoms were now explained, by Gilbert Newton Lewis in 1916, as the interactions between their constituent electrons. As the chemical properties of the elements were known to largely repeat themselves according to the periodic law, in 1919 the American chemist Irving Langmuir suggested that this could be explained if the electrons in an atom were connected or clustered in some manner. Groups of electrons were thought to occupy a set of electron shells about the nucleus. === Further developments in quantum physics === The Stern–Gerlach experiment of 1922 provided further evidence of the quantum nature of atomic properties. When a beam of silver atoms was passed through a specially shaped magnetic field, the beam was split in a way correlated with the direction of an atom's angular momentum, or spin. As this spin direction is initially random, the beam would be expected to deflect in a random direction. Instead, the beam was split into two directional components, corresponding to the atomic spin being oriented up or down with respect to the magnetic field.In 1925 Werner Heisenberg published the first consistent mathematical formulation of quantum mechanics (Matrix Mechanics). One year earlier, in 1924, Louis de Broglie had proposed that all particles behave to an extent like waves and, in 1926, Erwin Schrödinger used this idea to develop a mathematical model of the atom (Wave Mechanics) that described the electrons as three-dimensional waveforms rather than point particles. A consequence of using waveforms to describe particles is that it is mathematically impossible to obtain precise values for both the position and momentum of a particle at a given point in time; this became known as the uncertainty principle, formulated by Werner Heisenberg in 1927. In this concept, for a given accuracy in measuring a position one could only obtain a range of probable values for momentum, and vice versa. This model was able to explain observations of atomic behavior that previous models could not, such as certain structural and spectral patterns of atoms larger than hydrogen. Thus, the planetary model of the atom was discarded in favor of one that described atomic orbital zones around the nucleus where a given electron is most likely to be observed. === Discovery of the neutron === The development of the mass spectrometer allowed the mass of atoms to be measured with increased accuracy. The device uses a magnet to bend the trajectory of a beam of ions, and the amount of deflection is determined by the ratio of an atom's mass to its charge. The chemist Francis William Aston used this instrument to show that isotopes had different masses. The atomic mass of these isotopes varied by integer amounts, called the whole number rule. The explanation for these different isotopes awaited the discovery of the neutron, an uncharged particle with a mass similar to the proton, by the physicist James Chadwick in 1932. Isotopes were then explained as elements with the same number of protons, but different numbers of neutrons within the nucleus. === Fission, high-energy physics and condensed matter === In 1938, the German chemist Otto Hahn, a student of Rutherford, directed neutrons onto uranium atoms expecting to get transuranium elements. Instead, his chemical experiments showed barium as a product. A year later, Lise Meitner and her nephew Otto Frisch verified that Hahn's result were the first experimental nuclear fission. In 1944, Hahn received the Nobel prize in chemistry. Despite Hahn's efforts, the contributions of Meitner and Frisch were not recognized.In the 1950s, the development of improved particle accelerators and particle detectors allowed scientists to study the impacts of atoms moving at high energies. Neutrons and protons were found to be hadrons, or composites of smaller particles called quarks. The standard model of particle physics was developed that so far has successfully explained the properties of the nucleus in terms of these sub-atomic particles and the forces that govern their interactions. == Structure == === Subatomic particles === Though the word atom originally denoted a particle that cannot be cut into smaller particles, in modern scientific usage the atom is composed of various subatomic particles. The constituent particles of an atom are the electron, the proton and the neutron; all three are fermions. However, the hydrogen-1 atom has no neutrons and the hydron ion has no electrons. The electron is by far the least massive of these particles at 9.11×10−31 kg, with a negative electrical charge and a size that is too small to be measured using available techniques. It was the lightest particle with a positive rest mass measured, until the discovery of neutrino mass. Under ordinary conditions, electrons are bound to the positively charged nucleus by the attraction created from opposite electric charges. If an atom has more or fewer electrons than its atomic number, then it becomes respectively negatively or positively charged as a whole; a charged atom is called an ion. Electrons have been known since the late 19th century, mostly thanks to J.J. Thomson; see history of subatomic physics for details. Protons have a positive charge and a mass 1,836 times that of the electron, at 1.6726×10−27 kg. The number of protons in an atom is called its atomic number. Ernest Rutherford (1919) observed that nitrogen under alpha-particle bombardment ejects what appeared to be hydrogen nuclei. By 1920 he had accepted that the hydrogen nucleus is a distinct particle within the atom and named it proton. Neutrons have no electrical charge and have a free mass of 1,839 times the mass of the electron, or 1.6929×10−27 kg, the heaviest of the three constituent particles, but it can be reduced by the nuclear binding energy. Neutrons and protons (collectively known as nucleons) have comparable dimensions—on the order of 2.5×10−15 m—although the 'surface' of these particles is not sharply defined. The neutron was discovered in 1932 by the English physicist James Chadwick. In the Standard Model of physics, electrons are truly elementary particles with no internal structure. However, both protons and neutrons are composite particles composed of elementary particles called quarks. There are two types of quarks in atoms, each having a fractional electric charge. Protons are composed of two up quarks (each with charge +2/3) and one down quark (with a charge of −1/3). Neutrons consist of one up quark and two down quarks. This distinction accounts for the difference in mass and charge between the two particles.The quarks are held together by the strong interaction (or strong force), which is mediated by gluons. The protons and neutrons, in turn, are held to each other in the nucleus by the nuclear force, which is a residuum of the strong force that has somewhat different range-properties (see the article on the nuclear force for more). The gluon is a member of the family of gauge bosons, which are elementary particles that mediate physical forces. === Nucleus === All the bound protons and neutrons in an atom make up a tiny atomic nucleus, and are collectively called nucleons. The radius of a nucleus is approximately equal to 1.07 3√A fm, where A is the total number of nucleons. This is much smaller than the radius of the atom, which is on the order of 105 fm. The nucleons are bound together by a short-ranged attractive potential called the residual strong force. At distances smaller than 2.5 fm this force is much more powerful than the electrostatic force that causes positively charged protons to repel each other.Atoms of the same element have the same number of protons, called the atomic number. Within a single element, the number of neutrons may vary, determining the isotope of that element. The total number of protons and neutrons determine the nuclide. The number of neutrons relative to the protons determines the stability of the nucleus, with certain isotopes undergoing radioactive decay.The proton, the electron, and the neutron are classified as fermions. Fermions obey the Pauli exclusion principle which prohibits identical fermions, such as multiple protons, from occupying the same quantum state at the same time. Thus, every proton in the nucleus must occupy a quantum state different from all other protons, and the same applies to all neutrons of the nucleus and to all electrons of the electron cloud. However, a proton and a neutron are allowed to occupy the same quantum state.For atoms with low atomic numbers, a nucleus that has more neutrons than protons tends to drop to a lower energy state through radioactive decay so that the neutron–proton ratio is closer to one. However, as the atomic number increases, a higher proportion of neutrons is required to offset the mutual repulsion of the protons. Thus, there are no stable nuclei with equal proton and neutron numbers above atomic number Z = 20 (calcium) and as Z increases, the neutron–proton ratio of stable isotopes increases. The stable isotope with the highest proton–neutron ratio is lead-208 (about 1.5). The number of protons and neutrons in the atomic nucleus can be modified, although this can require very high energies because of the strong force. Nuclear fusion occurs when multiple atomic particles join to form a heavier nucleus, such as through the energetic collision of two nuclei. For example, at the core of the Sun protons require energies of 3–10 keV to overcome their mutual repulsion—the coulomb barrier—and fuse together into a single nucleus. Nuclear fission is the opposite process, causing a nucleus to split into two smaller nuclei—usually through radioactive decay. The nucleus can also be modified through bombardment by high energy subatomic particles or photons. If this modifies the number of protons in a nucleus, the atom changes to a different chemical element.If the mass of the nucleus following a fusion reaction is less than the sum of the masses of the separate particles, then the difference between these two values can be emitted as a type of usable energy (such as a gamma ray, or the kinetic energy of a beta particle), as described by Albert Einstein's mass–energy equivalence formula, E = mc2, where m is the mass loss and c is the speed of light. This deficit is part of the binding energy of the new nucleus, and it is the non-recoverable loss of the energy that causes the fused particles to remain together in a state that requires this energy to separate.The fusion of two nuclei that create larger nuclei with lower atomic numbers than iron and nickel—a total nucleon number of about 60—is usually an exothermic process that releases more energy than is required to bring them together. It is this energy-releasing process that makes nuclear fusion in stars a self-sustaining reaction. For heavier nuclei, the binding energy per nucleon in the nucleus begins to decrease. That means fusion processes producing nuclei that have atomic numbers higher than about 26, and atomic masses higher than about 60, is an endothermic process. These more massive nuclei can not undergo an energy-producing fusion reaction that can sustain the hydrostatic equilibrium of a star. === Electron cloud === The electrons in an atom are attracted to the protons in the nucleus by the electromagnetic force. This force binds the electrons inside an electrostatic potential well surrounding the smaller nucleus, which means that an external source of energy is needed for the electron to escape. The closer an electron is to the nucleus, the greater the attractive force. Hence electrons bound near the center of the potential well require more energy to escape than those at greater separations. Electrons, like other particles, have properties of both a particle and a wave. The electron cloud is a region inside the potential well where each electron forms a type of three-dimensional standing wave—a wave form that does not move relative to the nucleus. This behavior is defined by an atomic orbital, a mathematical function that characterises the probability that an electron appears to be at a particular location when its position is measured. Only a discrete (or quantized) set of these orbitals exist around the nucleus, as other possible wave patterns rapidly decay into a more stable form. Orbitals can have one or more ring or node structures, and differ from each other in size, shape and orientation. Each atomic orbital corresponds to a particular energy level of the electron. The electron can change its state to a higher energy level by absorbing a photon with sufficient energy to boost it into the new quantum state. Likewise, through spontaneous emission, an electron in a higher energy state can drop to a lower energy state while radiating the excess energy as a photon. These characteristic energy values, defined by the differences in the energies of the quantum states, are responsible for atomic spectral lines.The amount of energy needed to remove or add an electron—the electron binding energy—is far less than the binding energy of nucleons. For example, it requires only 13.6 eV to strip a ground-state electron from a hydrogen atom, compared to 2.23 million eV for splitting a deuterium nucleus. Atoms are electrically neutral if they have an equal number of protons and electrons. Atoms that have either a deficit or a surplus of electrons are called ions. Electrons that are farthest from the nucleus may be transferred to other nearby atoms or shared between atoms. By this mechanism, atoms are able to bond into molecules and other types of chemical compounds like ionic and covalent network crystals. == Properties == === Nuclear properties === By definition, any two atoms with an identical number of protons in their nuclei belong to the same chemical element. Atoms with equal numbers of protons but a different number of neutrons are different isotopes of the same element. For example, all hydrogen atoms admit exactly one proton, but isotopes exist with no neutrons (hydrogen-1, by far the most common form, also called protium), one neutron (deuterium), two neutrons (tritium) and more than two neutrons. The known elements form a set of atomic numbers, from the single proton element hydrogen up to the 118-proton element oganesson. All known isotopes of elements with atomic numbers greater than 82 are radioactive, although the radioactivity of element 83 (bismuth) is so slight as to be practically negligible.About 339 nuclides occur naturally on Earth, of which 254 (about 75%) have not been observed to decay, and are referred to as "stable isotopes". However, only 90 of these nuclides are stable to all decay, even in theory. Another 164 (bringing the total to 254) have not been observed to decay, even though in theory it is energetically possible. These are also formally classified as "stable". An additional 34 radioactive nuclides have half-lives longer than 80 million years, and are long-lived enough to be present from the birth of the solar system. This collection of 288 nuclides are known as primordial nuclides. Finally, an additional 51 short-lived nuclides are known to occur naturally, as daughter products of primordial nuclide decay (such as radium from uranium), or else as products of natural energetic processes on Earth, such as cosmic ray bombardment (for example, carbon-14).For 80 of the chemical elements, at least one stable isotope exists. As a rule, there is only a handful of stable isotopes for each of these elements, the average being 3.2 stable isotopes per element. Twenty-six elements have only a single stable isotope, while the largest number of stable isotopes observed for any element is ten, for the element tin. Elements 43, 61, and all elements numbered 83 or higher have no stable isotopes.Stability of isotopes is affected by the ratio of protons to neutrons, and also by the presence of certain "magic numbers" of neutrons or protons that represent closed and filled quantum shells. These quantum shells correspond to a set of energy levels within the shell model of the nucleus; filled shells, such as the filled shell of 50 protons for tin, confers unusual stability on the nuclide. Of the 254 known stable nuclides, only four have both an odd number of protons and odd number of neutrons: hydrogen-2 (deuterium), lithium-6, boron-10 and nitrogen-14. Also, only four naturally occurring, radioactive odd–odd nuclides have a half-life over a billion years: potassium-40, vanadium-50, lanthanum-138 and tantalum-180m. Most odd–odd nuclei are highly unstable with respect to beta decay, because the decay products are even–even, and are therefore more strongly bound, due to nuclear pairing effects. === Mass === The large majority of an atom's mass comes from the protons and neutrons that make it up. The total number of these particles (called "nucleons") in a given atom is called the mass number. It is a positive integer and dimensionless (instead of having dimension of mass), because it expresses a count. An example of use of a mass number is "carbon-12," which has 12 nucleons (six protons and six neutrons). The actual mass of an atom at rest is often expressed using the unified atomic mass unit (u), also called dalton (Da). This unit is defined as a twelfth of the mass of a free neutral atom of carbon-12, which is approximately 1.66×10−27 kg. Hydrogen-1 (the lightest isotope of hydrogen which is also the nuclide with the lowest mass) has an atomic weight of 1.007825 u. The value of this number is called the atomic mass. A given atom has an atomic mass approximately equal (within 1%) to its mass number times the atomic mass unit (for example the mass of a nitrogen-14 is roughly 14 u). However, this number will not be exactly an integer except in the case of carbon-12 (see below). The heaviest stable atom is lead-208, with a mass of 207.9766521 u.As even the most massive atoms are far too light to work with directly, chemists instead use the unit of moles. One mole of atoms of any element always has the same number of atoms (about 6.022×1023). This number was chosen so that if an element has an atomic mass of 1 u, a mole of atoms of that element has a mass close to one gram. Because of the definition of the unified atomic mass unit, each carbon-12 atom has an atomic mass of exactly 12 u, and so a mole of carbon-12 atoms weighs exactly 0.012 kg. === Shape and size === Atoms lack a well-defined outer boundary, so their dimensions are usually described in terms of an atomic radius. This is a measure of the distance out to which the electron cloud extends from the nucleus. However, this assumes the atom to exhibit a spherical shape, which is only obeyed for atoms in vacuum or free space. Atomic radii may be derived from the distances between two nuclei when the two atoms are joined in a chemical bond. The radius varies with the location of an atom on the atomic chart, the type of chemical bond, the number of neighboring atoms (coordination number) and a quantum mechanical property known as spin. On the periodic table of the elements, atom size tends to increase when moving down columns, but decrease when moving across rows (left to right). Consequently, the smallest atom is helium with a radius of 32 pm, while one of the largest is caesium at 225 pm.When subjected to external forces, like electrical fields, the shape of an atom may deviate from spherical symmetry. The deformation depends on the field magnitude and the orbital type of outer shell electrons, as shown by group-theoretical considerations. Aspherical deviations might be elicited for instance in crystals, where large crystal-electrical fields may occur at low-symmetry lattice sites. Significant ellipsoidal deformations have been shown to occur for sulfur ions and chalcogen ions in pyrite-type compounds. Atomic dimensions are thousands of times smaller than the wavelengths of light (400–700 nm) so they cannot be viewed using an optical microscope. However, individual atoms can be observed using a scanning tunneling microscope. To visualize the minuteness of the atom, consider that a typical human hair is about 1 million carbon atoms in width. A single drop of water contains about 2 sextillion (2×1021) atoms of oxygen, and twice the number of hydrogen atoms. A single carat diamond with a mass of 2×10−4 kg contains about 10 sextillion (1022) atoms of carbon. If an apple were magnified to the size of the Earth, then the atoms in the apple would be approximately the size of the original apple. === Radioactive decay === Every element has one or more isotopes that have unstable nuclei that are subject to radioactive decay, causing the nucleus to emit particles or electromagnetic radiation. Radioactivity can occur when the radius of a nucleus is large compared with the radius of the strong force, which only acts over distances on the order of 1 fm.The most common forms of radioactive decay are: Alpha decay: this process is caused when the nucleus emits an alpha particle, which is a helium nucleus consisting of two protons and two neutrons. The result of the emission is a new element with a lower atomic number. Beta decay (and electron capture): these processes are regulated by the weak force, and result from a transformation of a neutron into a proton, or a proton into a neutron. The neutron to proton transition is accompanied by the emission of an electron and an antineutrino, while proton to neutron transition (except in electron capture) causes the emission of a positron and a neutrino. The electron or positron emissions are called beta particles. Beta decay either increases or decreases the atomic number of the nucleus by one. Electron capture is more common than positron emission, because it requires less energy. In this type of decay, an electron is absorbed by the nucleus, rather than a positron emitted from the nucleus. A neutrino is still emitted in this process, and a proton changes to a neutron. Gamma decay: this process results from a change in the energy level of the nucleus to a lower state, resulting in the emission of electromagnetic radiation. The excited state of a nucleus which results in gamma emission usually occurs following the emission of an alpha or a beta particle. Thus, gamma decay usually follows alpha or beta decay.Other more rare types of radioactive decay include ejection of neutrons or protons or clusters of nucleons from a nucleus, or more than one beta particle. An analog of gamma emission which allows excited nuclei to lose energy in a different way, is internal conversion—a process that produces high-speed electrons that are not beta rays, followed by production of high-energy photons that are not gamma rays. A few large nuclei explode into two or more charged fragments of varying masses plus several neutrons, in a decay called spontaneous nuclear fission. Each radioactive isotope has a characteristic decay time period—the half-life—that is determined by the amount of time needed for half of a sample to decay. This is an exponential decay process that steadily decreases the proportion of the remaining isotope by 50% every half-life. Hence after two half-lives have passed only 25% of the isotope is present, and so forth. === Magnetic moment === Elementary particles possess an intrinsic quantum mechanical property known as spin. This is analogous to the angular momentum of an object that is spinning around its center of mass, although strictly speaking these particles are believed to be point-like and cannot be said to be rotating. Spin is measured in units of the reduced Planck constant (ħ), with electrons, protons and neutrons all having spin ½ ħ, or "spin-½". In an atom, electrons in motion around the nucleus possess orbital angular momentum in addition to their spin, while the nucleus itself possesses angular momentum due to its nuclear spin.The magnetic field produced by an atom—its magnetic moment—is determined by these various forms of angular momentum, just as a rotating charged object classically produces a magnetic field. However, the most dominant contribution comes from electron spin. Due to the nature of electrons to obey the Pauli exclusion principle, in which no two electrons may be found in the same quantum state, bound electrons pair up with each other, with one member of each pair in a spin up state and the other in the opposite, spin down state. Thus these spins cancel each other out, reducing the total magnetic dipole moment to zero in some atoms with even number of electrons.In ferromagnetic elements such as iron, cobalt and nickel, an odd number of electrons leads to an unpaired electron and a net overall magnetic moment. The orbitals of neighboring atoms overlap and a lower energy state is achieved when the spins of unpaired electrons are aligned with each other, a spontaneous process known as an exchange interaction. When the magnetic moments of ferromagnetic atoms are lined up, the material can produce a measurable macroscopic field. Paramagnetic materials have atoms with magnetic moments that line up in random directions when no magnetic field is present, but the magnetic moments of the individual atoms line up in the presence of a field.The nucleus of an atom will have no spin when it has even numbers of both neutrons and protons, but for other cases of odd numbers, the nucleus may have a spin. Normally nuclei with spin are aligned in random directions because of thermal equilibrium. However, for certain elements (such as xenon-129) it is possible to polarize a significant proportion of the nuclear spin states so that they are aligned in the same direction—a condition called hyperpolarization. This has important applications in magnetic resonance imaging. === Energy levels === The potential energy of an electron in an atom is negative, its dependence of its position reaches the minimum (the most absolute value) inside the nucleus, and vanishes when the distance from the nucleus goes to infinity, roughly in an inverse proportion to the distance. In the quantum-mechanical model, a bound electron can only occupy a set of states centered on the nucleus, and each state corresponds to a specific energy level; see time-independent Schrödinger equation for theoretical explanation. An energy level can be measured by the amount of energy needed to unbind the electron from the atom, and is usually given in units of electronvolts (eV). The lowest energy state of a bound electron is called the ground state, i.e. stationary state, while an electron transition to a higher level results in an excited state. The electron's energy raises when n increases because the (average) distance to the nucleus increases. Dependence of the energy on ℓ is caused not by electrostatic potential of the nucleus, but by interaction between electrons. For an electron to transition between two different states, e.g. grounded state to first excited level (ionization), it must absorb or emit a photon at an energy matching the difference in the potential energy of those levels, according to Niels Bohr model, what can be precisely calculated by the Schrödinger equation. Electrons jump between orbitals in a particle-like fashion. For example, if a single photon strikes the electrons, only a single electron changes states in response to the photon; see Electron properties. The energy of an emitted photon is proportional to its frequency, so these specific energy levels appear as distinct bands in the electromagnetic spectrum. Each element has a characteristic spectrum that can depend on the nuclear charge, subshells filled by electrons, the electromagnetic interactions between the electrons and other factors. When a continuous spectrum of energy is passed through a gas or plasma, some of the photons are absorbed by atoms, causing electrons to change their energy level. Those excited electrons that remain bound to their atom spontaneously emit this energy as a photon, traveling in a random direction, and so drop back to lower energy levels. Thus the atoms behave like a filter that forms a series of dark absorption bands in the energy output. (An observer viewing the atoms from a view that does not include the continuous spectrum in the background, instead sees a series of emission lines from the photons emitted by the atoms.) Spectroscopic measurements of the strength and width of atomic spectral lines allow the composition and physical properties of a substance to be determined.Close examination of the spectral lines reveals that some display a fine structure splitting. This occurs because of spin–orbit coupling, which is an interaction between the spin and motion of the outermost electron. When an atom is in an external magnetic field, spectral lines become split into three or more components; a phenomenon called the Zeeman effect. This is caused by the interaction of the magnetic field with the magnetic moment of the atom and its electrons. Some atoms can have multiple electron configurations with the same energy level, which thus appear as a single spectral line. The interaction of the magnetic field with the atom shifts these electron configurations to slightly different energy levels, resulting in multiple spectral lines. The presence of an external electric field can cause a comparable splitting and shifting of spectral lines by modifying the electron energy levels, a phenomenon called the Stark effect.If a bound electron is in an excited state, an interacting photon with the proper energy can cause stimulated emission of a photon with a matching energy level. For this to occur, the electron must drop to a lower energy state that has an energy difference matching the energy of the interacting photon. The emitted photon and the interacting photon then move off in parallel and with matching phases. That is, the wave patterns of the two photons are synchronized. This physical property is used to make lasers, which can emit a coherent beam of light energy in a narrow frequency band. === Valence and bonding behavior === Valency is the combining power of an element. It is equal to number of hydrogen atoms that atom can combine or displace in forming compounds. The outermost electron shell of an atom in its uncombined state is known as the valence shell, and the electrons in that shell are called valence electrons. The number of valence electrons determines the bonding behavior with other atoms. Atoms tend to chemically react with each other in a manner that fills (or empties) their outer valence shells. For example, a transfer of a single electron between atoms is a useful approximation for bonds that form between atoms with one-electron more than a filled shell, and others that are one-electron short of a full shell, such as occurs in the compound sodium chloride and other chemical ionic salts. However, many elements display multiple valences, or tendencies to share differing numbers of electrons in different compounds. Thus, chemical bonding between these elements takes many forms of electron-sharing that are more than simple electron transfers. Examples include the element carbon and the organic compounds.The chemical elements are often displayed in a periodic table that is laid out to display recurring chemical properties, and elements with the same number of valence electrons form a group that is aligned in the same column of the table. (The horizontal rows correspond to the filling of a quantum shell of electrons.) The elements at the far right of the table have their outer shell completely filled with electrons, which results in chemically inert elements known as the noble gases. === States === Quantities of atoms are found in different states of matter that depend on the physical conditions, such as temperature and pressure. By varying the conditions, materials can transition between solids, liquids, gases and plasmas. Within a state, a material can also exist in different allotropes. An example of this is solid carbon, which can exist as graphite or diamond. Gaseous allotropes exist as well, such as dioxygen and ozone. At temperatures close to absolute zero, atoms can form a Bose–Einstein condensate, at which point quantum mechanical effects, which are normally only observed at the atomic scale, become apparent on a macroscopic scale. This super-cooled collection of atoms then behaves as a single super atom, which may allow fundamental checks of quantum mechanical behavior. == Identification == The scanning tunneling microscope is a device for viewing surfaces at the atomic level. It uses the quantum tunneling phenomenon, which allows particles to pass through a barrier that would normally be insurmountable. Electrons tunnel through the vacuum between two planar metal electrodes, on each of which is an adsorbed atom, providing a tunneling-current density that can be measured. Scanning one atom (taken as the tip) as it moves past the other (the sample) permits plotting of tip displacement versus lateral separation for a constant current. The calculation shows the extent to which scanning-tunneling-microscope images of an individual atom are visible. It confirms that for low bias, the microscope images the space-averaged dimensions of the electron orbitals across closely packed energy levels—the Fermi level local density of states.An atom can be ionized by removing one of its electrons. The electric charge causes the trajectory of an atom to bend when it passes through a magnetic field. The radius by which the trajectory of a moving ion is turned by the magnetic field is determined by the mass of the atom. The mass spectrometer uses this principle to measure the mass-to-charge ratio of ions. If a sample contains multiple isotopes, the mass spectrometer can determine the proportion of each isotope in the sample by measuring the intensity of the different beams of ions. Techniques to vaporize atoms include inductively coupled plasma atomic emission spectroscopy and inductively coupled plasma mass spectrometry, both of which use a plasma to vaporize samples for analysis.A more area-selective method is electron energy loss spectroscopy, which measures the energy loss of an electron beam within a transmission electron microscope when it interacts with a portion of a sample. The atom-probe tomograph has sub-nanometer resolution in 3-D and can chemically identify individual atoms using time-of-flight mass spectrometry.Spectra of excited states can be used to analyze the atomic composition of distant stars. Specific light wavelengths contained in the observed light from stars can be separated out and related to the quantized transitions in free gas atoms. These colors can be replicated using a gas-discharge lamp containing the same element. Helium was discovered in this way in the spectrum of the Sun 23 years before it was found on Earth. == Origin and current state == Atoms form about 4% of the total energy density of the observable Universe, with an average density of about 0.25 atoms/m3. Within a galaxy such as the Milky Way, atoms have a much higher concentration, with the density of matter in the interstellar medium (ISM) ranging from 105 to 109 atoms/m3. The Sun is believed to be inside the Local Bubble, a region of highly ionized gas, so the density in the solar neighborhood is only about 103 atoms/m3. Stars form from dense clouds in the ISM, and the evolutionary processes of stars result in the steady enrichment of the ISM with elements more massive than hydrogen and helium. Up to 95% of the Milky Way's atoms are concentrated inside stars and the total mass of atoms forms about 10% of the mass of the galaxy. (The remainder of the mass is an unknown dark matter.) === Formation === Electrons are thought to exist in the Universe since early stages of the Big Bang. Atomic nuclei forms in nucleosynthesis reactions. In about three minutes Big Bang nucleosynthesis produced most of the helium, lithium, and deuterium in the Universe, and perhaps some of the beryllium and boron.Ubiquitousness and stability of atoms relies on their binding energy, which means that an atom has a lower energy than an unbound system of the nucleus and electrons. Where the temperature is much higher than ionization potential, the matter exists in the form of plasma—a gas of positively charged ions (possibly, bare nuclei) and electrons. When the temperature drops below the ionization potential, atoms become statistically favorable. Atoms (complete with bound electrons) became to dominate over charged particles 380,000 years after the Big Bang—an epoch called recombination, when the expanding Universe cooled enough to allow electrons to become attached to nuclei.Since the Big Bang, which produced no carbon or heavier elements, atomic nuclei have been combined in stars through the process of nuclear fusion to produce more of the element helium, and (via the triple alpha process) the sequence of elements from carbon up to iron; see stellar nucleosynthesis for details. Isotopes such as lithium-6, as well as some beryllium and boron are generated in space through cosmic ray spallation. This occurs when a high-energy proton strikes an atomic nucleus, causing large numbers of nucleons to be ejected. Elements heavier than iron were produced in supernovae through the r-process and in AGB stars through the s-process, both of which involve the capture of neutrons by atomic nuclei. Elements such as lead formed largely through the radioactive decay of heavier elements. === Earth === Most of the atoms that make up the Earth and its inhabitants were present in their current form in the nebula that collapsed out of a molecular cloud to form the Solar System. The rest are the result of radioactive decay, and their relative proportion can be used to determine the age of the Earth through radiometric dating. Most of the helium in the crust of the Earth (about 99% of the helium from gas wells, as shown by its lower abundance of helium-3) is a product of alpha decay.There are a few trace atoms on Earth that were not present at the beginning (i.e., not "primordial"), nor are results of radioactive decay. Carbon-14 is continuously generated by cosmic rays in the atmosphere. Some atoms on Earth have been artificially generated either deliberately or as by-products of nuclear reactors or explosions. Of the transuranic elements—those with atomic numbers greater than 92—only plutonium and neptunium occur naturally on Earth. Transuranic elements have radioactive lifetimes shorter than the current age of the Earth and thus identifiable quantities of these elements have long since decayed, with the exception of traces of plutonium-244 possibly deposited by cosmic dust. Natural deposits of plutonium and neptunium are produced by neutron capture in uranium ore.The Earth contains approximately 1.33×1050 atoms. Although small numbers of independent atoms of noble gases exist, such as argon, neon, and helium, 99% of the atmosphere is bound in the form of molecules, including carbon dioxide and diatomic oxygen and nitrogen. At the surface of the Earth, an overwhelming majority of atoms combine to form various compounds, including water, salt, silicates and oxides. Atoms can also combine to create materials that do not consist of discrete molecules, including crystals and liquid or solid metals. This atomic matter forms networked arrangements that lack the particular type of small-scale interrupted order associated with molecular matter. === Rare and theoretical forms === ==== Superheavy elements ==== While isotopes with atomic numbers higher than lead (82) are known to be radioactive, an "island of stability" has been proposed for some elements with atomic numbers above 103. These superheavy elements may have a nucleus that is relatively stable against radioactive decay. The most likely candidate for a stable superheavy atom, unbihexium, has 126 protons and 184 neutrons. ==== Exotic matter ==== Each particle of matter has a corresponding antimatter particle with the opposite electrical charge. Thus, the positron is a positively charged antielectron and the antiproton is a negatively charged equivalent of a proton. When a matter and corresponding antimatter particle meet, they annihilate each other. Because of this, along with an imbalance between the number of matter and antimatter particles, the latter are rare in the universe. The first causes of this imbalance are not yet fully understood, although theories of baryogenesis may offer an explanation. As a result, no antimatter atoms have been discovered in nature. However, in 1996 the antimatter counterpart of the hydrogen atom (antihydrogen) was synthesized at the CERN laboratory in Geneva.Other exotic atoms have been created by replacing one of the protons, neutrons or electrons with other particles that have the same charge. For example, an electron can be replaced by a more massive muon, forming a muonic atom. These types of atoms can be used to test the fundamental predictions of physics. == See also == == Notes == == References == == Sources == == Further reading == == External links == "A Look Inside the Atom".
