Ethiopia was a monarchy for most of its history, and the Ethiopian dynasty traces its roots to the 2nd century BC. Ethiopia is also one of the oldest sites of human existence known to scientists today, having yielded some of humanity's oldest traces. It may be the region from which Homo sapiens first set out for the Middle East and points beyond. Alongside Rome, Persia, China and India, the Ethiopian Aksum Empire was considered one of the great world powers of the 3rd century. During the Scramble for Africa, Ethiopia was the only African country beside Liberia that retained its sovereignty as a recognized independent country, and was one of only four African members of the League of Nations. After a brief period of Italian occupation, Ethiopia became a charter member of the United Nations. When other African nations received their independence following World War II, many of them adopted the colors of Ethiopia's flag, and Addis Ababa became the location of several international organizations focused on Africa.

Argentina is a country in South America, the continent's second largest by land area, after Brazil. It is constituted as a federation of 23 provinces and an autonomous city, Buenos Aires. It is the eighth-largest country in the world by land area and the largest among Spanish-speaking nations.

Argentina's continental area is between the Andes mountain range in the west and the Atlantic Ocean in the east. It borders Paraguay and Bolivia to the north, Brazil and Uruguay to the northeast, and Chile to the west and south. Argentine claims over Antarctica, as well as overlapping claims made by Chile and the United Kingdom, are suspended by the Antarctic Treaty of 1961. Argentina also claims the Falkland Islands (Spanish: Islas Malvinas) and South Georgia and the South Sandwich Islands, which are administered by the United Kingdom as British Overseas Territories.

Greek mythology is the body of myths and legends belonging to the ancient Greeks, concerning their gods and heroes, the nature of the world, and the origins and significance of their own cult and ritual practices. They were a part of religion in ancient Greece and are part of religion in modern Greece and around the world as Hellenismos. Modern scholars refer to, and study the myths in an attempt to throw light on the religious and political institutions of Ancient Greece, its civilization, and to gain understanding of the nature of myth-making itself.

The oldest known Greek literary sources, Homer's epic poems Iliad and Odyssey, focus on events surrounding the Trojan War. Two poems by Homer's near contemporary Hesiod, the Theogony and the Works and Days, contain accounts of the genesis of the world, the succession of divine rulers, the succession of human ages, the origin of human woes, and the origin of sacrificial practices. Myths also are preserved in the Homeric Hymns, in fragments of epic poems of the Epic Cycle, in lyric poems, in the works of the tragedians of the fifth century BC, in writings of scholars and poets of the Hellenistic Age and in texts from the time of the Roman Empire by writers such as Plutarch and Pausanias.

South America is a continent located in the Western Hemisphere, mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere. The continent is also considered a subcontinent of the Americas. It is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. It includes twelve independent countries—Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela—and French Guiana, which is an overseas region of France as well as the Falkland Islands, which are an overseas territory of the UK. The South American countries that border the Caribbean Sea—Colombia, Venezuela, Guyana, Suriname, and French Guiana—are also known as Caribbean South America.

Prior to European colonization, the Andean region of Bolivia was a part of the Inca Empire – the largest state in Pre-Columbian America. The Spanish Empire conquered the region in the 16th century. During most of the Spanish colonial period, this territory was called Upper Peru and was under the administration of the Viceroyalty of Peru, which included most of Spain's South American colonies. After declaring independence in 1809, 16 years of war followed before the establishment of the Republic, named for Simón Bolívar, on 6 August 1825. Bolivia has struggled through periods of political instability, dictatorships and economic woes.

Brazil was a colony of Portugal from the landing of Pedro Álvares Cabral in 1500 until 1815, when it was elevated to the rank of kingdom and the United Kingdom of Portugal, Brazil and the Algarves was formed. The colonial bond was in fact broken in 1808, when the capital of the Portuguese colonial empire was transferred from Lisbon to Rio de Janeiro, after Napoleon invaded Portugal. Independence was achieved in 1822 with the formation of the Empire of Brazil, a unitary state governed under a constitutional monarchy and a parliamentary system. The country became a presidential republic in 1889, when a military coup d'état proclaimed the Republic, although the bicameral legislature, now called Congress, dates back to the ratification of the first constitution in 1824. Its current Constitution, formulated in 1988, defines Brazil as a Federal Republic. The Federation is formed by the union of the Federal District, the 26 States, and the 5,564 Municipalities.

Prior to the arrival of the Spanish in the 16th century, northern and central Chile was under Inca rule while the indigenous Mapuche inhabited southern Chile. Chile declared its independence from Spain on 12 February 1818. In the War of the Pacific (1879–83), Chile defeated Peru and Bolivia and won its current northern territory. It was not until the 1880s that the Mapuche were completely subjugated. Although relatively free of the coups and arbitrary governments that blighted South America, Chile endured the 17-year long military dictatorship (1973–1990) of Augusto Pinochet that left more than 3,000 people dead or missing.

The territory of what is now Colombia was originally inhabited by indigenous peoples including the Muisca, Quimbaya, and Tairona. The Spanish arrived in 1499 and initiated a period of conquest and colonization ultimately creating the Viceroyalty of New Granada (comprising modern-day Colombia, Venezuela, Ecuador, north-western Brazil and Panama), with its capital at Bogotá. Independence from Spain was won in 1819, but by 1830 "Gran Colombia" had collapsed with the secession of Venezuela and Ecuador. What is now Colombia and Panama emerged as the Republic of New Granada. The new nation experimented with federalism as the Granadine Confederation (1858), and then the United States of Colombia (1863), before the Republic of Colombia was finally declared in 1886. Panama seceded in 1903.

Colombia was the first constitutional government in South America, and an important promoter of the Pan American organizations, initially through the Congress of Panama and later, during the 20th century as founder of the Organization of American States. The Liberal and Conservative parties, founded in 1848 and 1849, are two of the oldest surviving political parties in the Americas.

Charles Robert Darwin was an English naturalist. He established that all species of life have descended over time from common ancestors, and proposed the scientific theory that this branching pattern of evolution resulted from a process that he called natural selection.

Darwin published his theory with compelling evidence for evolution in his 1859 book On the Origin of Species, overcoming scientific rejection of earlier concepts of transmutation of species. By the 1870s the scientific community and much of the general public had accepted evolution as a fact. However, many favored competing explanations and it was not until the emergence of the modern evolutionary synthesis from the 1930s to the 1950s that a broad consensus developed in which natural selection was the basic mechanism of evolution. In modified form, Darwin's scientific discovery is the unifying theory of the life sciences, explaining the diversity of life.

The Galápagos Islands (official name: Archipiélago de Colón; other Spanish names: Islas de Colón or Islas Galápagos) are an archipelago of volcanic islands distributed around the equator in the Pacific Ocean, 972 km west of continental Ecuador, of which they are a part.

The first crude navigation chart of the islands was made by the buccaneer Ambrose Cowley in 1684. He named the individual islands after some of his fellow pirates or after the British noblemen who helped the privateer's cause. More recently, the Ecuadorian government gave most of the islands Spanish names. While the Spanish names are official, many users (especially ecological researchers) continue to use the older English names, principally because those were the names used when Charles Darwin visited.

The main spoken language in Ecuador is Spanish. Ecuador straddles the equator, from which it takes its name, and has an area of 275,830 km2 (106,500 sq mi). Its capital city is Quito, which was declared a World Heritage Site by UNESCO in the 1970s for having the best preserved and least altered historic center in Latin America. The country's largest city is Guayaquil. The historic center of Cuenca, the third largest city in the country, was also declared a World Heritage Site in 1999, for being an outstanding example of a planned inland Spanish style colonial city in the Americas. Ecuador is also home—despite its size—to a great variety of species, many of them endemic, like those of the Galápagos islands. This species diversity makes Ecuador one of the 17 megadiverse countries in the world. The new constitution of 2008 is the first in the world to recognize legally enforceable Rights of Nature, or ecosystem rights.

French Guiana (officially just Guyane) is an overseas region of France, consisting of a single overseas department located on the northern Atlantic coast of South America.

The addition of the adjective "French" in English comes from colonial times when five such colonies existed (The Guianas), namely from west to east: Spanish Guiana (now Guayana Region in Venezuela), British Guiana (now Guyana), Dutch Guiana (now Suriname), French Guiana, and Portuguese Guiana (now Amapá, a state in far northern Brazil). French Guiana and the two larger countries to the north and west, Guyana and Suriname, are still often collectively referred to as the Guianas and comprise one large shield landmass.

Guyana previously the colony of British Guiana, is a sovereign state on the northern coast of South America that is culturally part of the Anglophone Caribbean. Guyana was a former colony of the Dutch and (for over 200 years) the British. It is the only state of the Commonwealth of Nations on mainland South America, and the only one on that continent where English is an official language. It is also a member of the Caribbean Community (CARICOM), which has its secretariat headquarters in Guyana's capital, Georgetown. Guyana achieved independence from the United Kingdom on 26 May 1966, and became a republic on 23 February 1970. In 2008 the country joined the Union of South American Nations as a founding member.

Historically, the region known as "Guiana" or "Guyana" comprised the large shield landmass north of the Amazon River and east of the Orinoco River known as the "Land of many waters". Historical Guyana is made up of three Dutch colonies: Essequibo, Demerara, and Berbice.

The Guaraní have been living in Paraguay since prior to the arrival of Europeans in the 16th century, when Paraguay became part of the Spanish colonial empire. Following independence from Spain in 1811 Paraguay was ruled by a series of dictators who followed isolationist and protectionist policies. This development was truncated by the disastrous Paraguayan War (1864–1870) in which the country lost 60% to 70% of its population. During a large part of the 20th century the country was ruled by Alfredo Stroessner as one of the longest lived South American military dictatorships. In 1989 Stroessner was toppled and free elections celebrated in 1993. In 1994 Paraguay joined Argentina, Brazil and Uruguay to found Mercosur.

During World War II, American propaganda was used to increase support for the war and commitment to an Allied victory. Using a wide variety of media, propagandists fomented hatred for the enemy and support for America's allies, urged greater public effort for war production and victory gardens, persuaded people to make do with what they had so that more material could be used for the war effort, and sold war bonds.

Arthel Lane "Doc" Watson (born March 3, 1923) is an American guitar player, songwriter and singer of bluegrass, folk, country, blues and gospel music. He has won seven Grammy awards as well as a Grammy Lifetime Achievement Award. Watson's flatpicking skills and knowledge of traditional American music are highly regarded. He performed with his son Merle for over 15 years until Merle's death in 1985, in an accident on the family farm.

Peruvian territory was home to ancient cultures, spanning from the Norte Chico civilization, one of the oldest in the world, to the Inca Empire, the largest state in Pre-Columbian America. The Spanish Empire conquered the region in the 16th century and established a Viceroyalty, which included most of its South American colonies. After achieving independence in 1821, Peru has undergone periods of political unrest and fiscal crisis as well as periods of stability and economic upswing.

John Emmett Raitt (January 29, 1917[1] – February 20, 2005) was an American actor and singer best known for his performances in musical theater.

He is best known for his stage roles in the musicals Carousel, Oklahoma!, The Pajama Game, Carnival in Flanders, Three Wishes for Jamie, and A Joyful Noise, in which he set the standard for virile, handsome, strong-voiced leading men during the golden age of the Broadway musical. His only leading film role was in the 1957 movie version of The Pajama Game opposite Doris Day.

Suriname, officially the Republic of Suriname, is a country in northern South America. It borders French Guiana to the east, Guyana to the west, Brazil to the south, and the Atlantic Ocean to the north. Suriname was a former colony of the British and of the Dutch, and was previously known as Dutch Guiana. Suriname achieved independence from the Netherlands on 25 November 1975.

At just under 165,000 km2 (64,000 sq mi) Suriname is the smallest sovereign state in South America (French Guiana comprises less territory, but is French territory). It has an estimated population of approximately 490,000, most of whom live on the country's north coast, where the capital Paramaribo is located.

Folkstreams.net has two goals. One is to build a national preserve of hard-to-find documentary films about American folk or roots cultures. The other is to give them renewed life by streaming them on the internet. The films were produced by independent filmmakers in a golden age that began in the 1960s and was made possible by the development first of portable cameras and then capacity for synch sound. Their films focus on the culture, struggles, and arts of unnoticed Americans from many different regions and communities.

Venezuela was colonized by Spain in 1522, overcoming the resistance from indigenous peoples. It became the first Spanish American colony to declare independence (in 1811), but did not securely establish independence until 1821 (initially as a department of the federal republic of Gran Colombia, gaining full independence in 1830). During the 19th century Venezuela suffered political turmoils and dictatorship, and it was dominated by regional caudillos (military strongmen) well into the 20th century. The country first saw a democratic rule from 1945 to 1948, and, after a period of dictatorship has remained democratic since 1958, during which time most countries of Latin America suffered one or more military dictatorships. Economic crisis in the 1980s and 1990s led to a political crisis which saw hundreds dead in the Caracazo riots of 1989, two attempted coups in 1992, and the impeachment of President Carlos Andrés Pérez for embezzlement of public funds in 1993. A collapse in confidence in the existing parties saw the 1998 election of former career officer Hugo Chávez, and the launch of the Bolivarian Revolution, beginning with a 1999 Constituent Assembly to write a new Constitution of Venezuela.

Artificial intelligence (AI) is the intelligence of machines and the branch of computer science that aims to create it. defines it as "the science and engineering of making intelligent machines.

The field was founded on the claim that a central property of humans, intelligence—the sapience of Homo sapiens—can be so precisely described that it can be simulated by a machine.

Watson is an artificial intelligence computer system capable of answering questions posed in natural language, developed in IBM's DeepQA project by a research team led by principal investigator David Ferrucci.

In nature, every advantage increases an animal's chances of survival, and therefore its chances of reproducing. This simple fact has caused animal species to evolve a number of special adaptations that help them find food and keep them from becom­ing food. One of the most widespread and varied adaptations is natural camouflage, an animal's ability to hide itself from predator and prey.

The polka is a Central European dance and also a genre of dance music familiar throughout Europe and the Americas. It originated in the middle of the 19th century in Bohemia. Polka is still a popular genre of folk music in many European countries and is performed by folk artists in Poland, Latvia, Lithuania, Czech Republic, Netherlands, Croatia, Slovenia, Germany, Hungary, Austria, Switzerland, Italy, Ukraine, Belarus, Russia and Slovakia. Local varieties of this dance are also found in the Nordic countries, United Kingdom, Republic of Ireland, Latin America (especially Mexico), and in the United States.

James Cleveland "Jesse" Owens (September 12, 1913 – March 31, 1980) was an American track and field athlete who specialized in the sprints and the long jump. He participated in the 1936 Summer Olympics in Berlin, Germany, where he achieved international fame by winning four gold medals: one each in the 100 meters, the 200 meters, the long jump, and as part of the 4x100 meter relay team. He was the most successful athlete at the 1936 Summer Olympics, a victory more poignant and often noted because Adolf Hitler had intended the 1936 games to showcase his Aryan ideals and prowess.

Is it possible to heal wounds and bitterness passed down through generations? An Orthodox Jewish father tries to alert his adult sons to the dangers of creating impenetrable barriers between themselves and those outside their faith. He takes them on an emotional journey to Poland to track down the family who risked their lives to hide their grandfather for more than two years during World War II.

The Veterans History Project (VHP) collects, preserves, and makes available the personal stories of American war veterans and civilian workers who supported them. These collections of firsthand accounts are gathered for use by researchers and so that future generations may hear directly from veterans to better understand the realities of war.

Early Abstractions is a collection of seven short animated films created by Harry Everett Smith between 1939 and 1956. Each film is between two and six minutes long, and is named according to the chronological order in which it was made. The collection includes Numbers 1–5, 7, and 10, while the missing Numbers 6, 8, and 9 are presumed to have been lost.

The idea of the numbering was to suggest a coherent link between each individual film, and that they were to be treated not just on their own but as part of a larger body of work. Of the missing chapters, Number 6 was made up of three dimensional optically printed abstractions; Number 8 was a black and white collage of clippings taken from nineteenth century ladies wear catalogues and elocution books, and Number 9 was a color collage of biology books and nineteenth century temperance[disambiguation needed ] posters. The remaining films show a gradual evolution in Smith's technical complexity, with blunt abstraction rudimentary motion more prominent in the early shorts, in contrast to an allegoric dance of Tarot cards, and Buddhist and Cabalistic symbols.

Initially recorded with no sound, a medley of music by The Beatles was added retrospectively. Because the songs do not exactly sync up with each individual film, some critics have opined that this does not enhance the film, and recommend watching it in silence.

In 2006, Early Abstractions was selected to the National Film Registry by the Librarian of Congress for its "cultural, historical, or aesthetic significance".

The Anthology of American Folk Music is a six-album compilation released in 1952 by Folkways Records, comprising eighty-four American folk, blues and country music recordings that were originally issued from 1927 to 1932.

Experimental filmmaker and notable eccentric Harry Smith compiled the music from his personal collection of 78 rpm records. The album is famous due to its role as a touchstone for the American folk music revival in the 1950s and 1960s. The Anthology was released for compact disc by Smithsonian Folkways Recordings on August 19, 1997.

The Veterans History Project of the American Folklife Center collects, preserves, and makes accessible the personal accounts of American war veterans so that future generations may hear directly from veterans and better understand the realities of war.

Veterans Day, formerly Armistice Day, is an annual United States holiday honoring armed service veterans. It is a federal holiday that is observed on November 11. It coincides with other holidays such as Armistice Day or Remembrance Day, which are celebrated in other parts of the world and also mark the anniversary of the signing of the Armistice that ended World War I. (Major hostilities of World War I were formally ended at the 11th hour of the 11th day of the 11th month of 1918 with the German signing of the Armistice.)

Memorial Day is a federal holiday observed annually in the United States on the last Monday of May. Formerly known as Decoration Day, it originated after the American Civil War to commemorate the fallen Union soldiers of the Civil War. (Southern ladies organizations and southern schoolchildren had decorated Confederate graves in Richmond and other cities during the Civil War, but each region had its own date. Most dates were in May.) By the 20th century Memorial Day had been extended to honor all Americans who have died in all wars. Memorial Day is a day of remembering the men and women who died while serving in the United States Armed Forces. As a marker it typically marks the start of the summer vacation season, while Labor Day marks its end.

Coriolanus is a tragedy by William Shakespeare, based on the life of the legendary Roman leader, Gaius Martius Coriolanus.

Antony and Cleopatra is a tragedy by William Shakespeare. It was first printed in the First Folio of 1623.

The plot is based on Thomas North's translation of Plutarch's Life of Markus Antonius and follows the relationship between Cleopatra and Mark Antony from the time of the Parthian War to Cleopatra's suicide. The major antagonist is Octavius Caesar, one of Antony's fellow triumvirs and the future first emperor of Rome. The tragedy is a Roman play characterized by swift, panoramic shifts in geographical locations and in registers, alternating between sensual, imaginative Alexandria and the more pragmatic, austere Rome. Many consider the role of Cleopatra in this play one of the most complex female roles in Shakespeare's work. She is frequently vain and histrionic, provoking an audience almost to scorn; at the same time, Shakespeare's efforts invest both her and Antony with tragic grandeur. These contradictory features have led to famously divided critical responses.

Troilus and Cressida is a tragedy by William Shakespeare, believed to have been written in 1602. The play (also described as one of Shakespeare's problem plays) is not a conventional tragedy, since its protagonist (Troilus) does not die. The play ends instead on a very bleak note with the death of the noble Trojan Hector and destruction of the love between Troilus and Cressida. Throughout the play, the tone lurches wildly between bawdy comedy and tragic gloom, and readers and theatre-goers have frequently found it difficult to understand how one is meant to respond to the characters.

Peter "Pete" Seeger (born May 3, 1919) is an American folk singer and an iconic figure in the mid-20th-century American folk music revival. A fixture on nationwide radio in the 1940s, he also had a string of hit records during the early 1950s as a member of The Weavers, most notably their recording of Lead Belly's "Goodnight, Irene", which topped the charts for 13 weeks in 1950. Members of The Weavers were blacklisted during the McCarthy Era. In the 1960s, he re-emerged on the public scene as a prominent singer of protest music in support of international disarmament, civil rights, and environmental causes.

As a song writer, he is best known as the author or co-author of "Where Have All the Flowers Gone?", "If I Had a Hammer (The Hammer Song)", (composed with Lee Hays of The Weavers), and "Turn, Turn, Turn!", which have been recorded by many artists both in and outside the folk revival movement and are still sung throughout the world. "Flowers" was a hit recording for The Kingston Trio (1962); Marlene Dietrich, who recorded it in English, German and French (1962); and Johnny Rivers (1965). "If I Had a Hammer" was a hit for Peter, Paul & Mary (1962) and Trini Lopez (1963), while The Byrds popularized "Turn, Turn, Turn!" in the mid-1960s, as did Judy Collins in 1964, and The Seekers in 1966. Seeger was one of the folksingers most responsible for popularizing the spiritual "We Shall Overcome" (also recorded by Joan Baez and many other singer-activists) that became the acknowledged anthem of the 1960s American Civil Rights Movement, soon after folk singer and activist Guy Carawan introduced it at the founding meeting of the Student Nonviolent Coordinating Committee (SNCC) in 1960. In the PBS "American Masters" episode Pete Seeger: The Power of Song, Seeger states it was he who changed the lyric from the traditional "We will overcome" to the more singable "We shall overcome".

Woodrow Wilson "Woody" Guthrie (July 14, 1912 – October 3, 1967) is best known as an American singer-songwriter and folk musician, whose musical legacy includes hundreds of political, traditional and children's songs, ballads and improvised works. He frequently performed with the slogan This Machine Kills Fascists displayed on his guitar. His best-known song is "This Land Is Your Land." Many of his recorded songs are archived in the Library of Congress. Such songwriters as Bob Dylan, Phil Ochs, Bruce Springsteen, John Mellencamp, Pete Seeger, Joe Strummer, Billy Bragg and Tom Paxton have acknowledged Guthrie as a major influence.

Guthrie traveled with migrant workers from Oklahoma to California and learned traditional folk and blues songs. Many of his songs are about his experiences in the Dust Bowl era during the Great Depression, earning him the nickname the "Dust Bowl Troubadour." Throughout his life Guthrie was associated with United States communist groups, though he was seemingly not a member of any.

Guthrie was married three times and fathered eight children, including American folk musician Arlo Guthrie. He is the grandfather of musician Sarah Lee Guthrie. Guthrie died from complications of Huntington's disease, a progressive genetic neurological disorder. During his later years, in spite of his illness, Guthrie served as a figurehead in the folk movement, providing inspiration to a generation of new folk musicians, including mentor relationships with Ramblin' Jack Elliott and Bob Dylan.

JAZZ: The Smithsonian Anthology traces the turning points of this 20th-century tale through its legendary innovators and notable styles. The great American musical invention of the 20th century, jazz is an ever-youthful, still evolving music of beauty, sensitivity, and brilliance that has produced (and been produced by) an extraordinary progression of talented artists.

In Pre-Columbian Mexico many cultures matured into advanced civilizations such as the Olmec, the Toltec, the Teotihuacan, the Zapotec, the Maya and the Aztec before the first contact with Europeans. In 1521, Spain conquered and colonized the territory from its base in México-Tenochtitlan, which was administered as the Viceroyalty of New Spain. This territory would eventually become Mexico as the colony's independence was recognized in 1821. The post-independence period was characterized by economic instability, the Mexican-American War and territorial cession to the United States, a civil war, two empires and a domestic dictatorship. The latter led to the Mexican Revolution in 1910, which culminated with the promulgation of the 1917 Constitution and the emergence of the country's current political system.

William Shakespeare (baptised 26 April 1564; died 23 April 1616) was an English poet and playwright, widely regarded as the greatest writer in the English language and the world's pre-eminent dramatist. He is often called England's national poet and the "Bard of Avon". His surviving works, including some collaborations, consist of about 38 plays, 154 sonnets, two long narrative poems, and several other poems. His plays have been translated into every major living language and are performed more often than those of any other playwright.

The sun contains 99.9 percent of all the matter in our solar system and sheds hot plasma at nearly a million miles an hour. The temperature at its core is a staggering 27 million degrees Fahrenheit. It convulses, it blazes, it sings. You know it as the sun. Scientists know it as one of the most amazing physics laboratories in the universe. Now, with the help of new spacecraft and Earth-based telescopes, scientists are seeing the sun as they never have before and even recreating what happens at its very center in labs here on Earth. Their work will help us understand aspects of the sun that have puzzled scientists for decades. But more critically, it may help us predict and track solar storms that have the power to zap our power grid, shut down telecommunications, and ground global air travel for days, weeks, or even longer. Such storms have happened before—but never in the modern era of satellite communication. "Secrets of the Sun" reveals a bright new dawn in our understanding of our nearest star—one that might help keep our planet from going dark.

A diverse and multifaceted cultural and educational enterprise, the National Museum of the American Indian (NMAI) is an active and visible component of the Smithsonian Institution, the world's largest museum complex.

The museum provides a variety of materials for use in the classroom. All have been developed by the museum's education staff in collaboration with Native community members. These materials offer rich Native perspectives on the history and contemporary life of many different Native tribes.

This is a collection of free materials that teachers may order over the Internet.

The First Part of King Henry the Sixth is history play by William Shakespeare, believed written in approximately 1588–1590. It is the first in the cycle of four plays often referred to as "The First Tetralogy".

The Second Part of King Henry the Sixth, or Henry VI, Part 2, is a history play by William Shakespeare believed written in approximately 1590-91. It is the second part of the trilogy on Henry VI, and often grouped together with Richard III as a tetralogy on The Wars of the Roses—the success of which established Shakespeare's reputation as a playwright.

Labor Day, the first Monday in September, is a creation of the labor movement and is dedicated to the social and economic achievements of American workers. It constitutes a yearly national tribute to the contributions workers have made to the strength, prosperity, and well-being of our country.

The Holocaust was the systematic, bureaucratic, state-sponsored persecution and murder of approximately six million Jews by the Nazi regime and its collaborators. "Holocaust" is a word of Greek origin meaning "sacrifice by fire." The Nazis, who came to power in Germany in January 1933, believed that Germans were "racially superior" and that the Jews, deemed "inferior," were an alien threat to the so-called German racial community.

During the era of the Holocaust, German authorities also targeted other groups because of their perceived "racial inferiority": Roma (Gypsies), the disabled, and some of the Slavic peoples (Poles, Russians, and others). Other groups were persecuted on political, ideological, and behavioral grounds, among them Communists, Socialists, Jehovah's Witnesses, and homosexuals.

The Holocaust involved more than the Jews; because of eugenics, the persecuted included gypsies, Poles, African-Germans, prisoners of war, the disabled, homosexuals, Germans(!) and other "deviants."

From 1933 to 1945, Nazi Germany’s government led by Adolf Hitler promoted a nationalism that combined territorial expansion with claims of biological superiority—an “Aryan master race”—and virulent antisemitism. Driven by a racist ideology legitimized by German scientists, the Nazis attempted to eliminate all of Europe’s Jews, ultimately killing six million in the Holocaust. Many others also became victims of persecution and murder in the Nazis’ campaign to cleanse German society of individuals viewed as threats to the “health” of the nation.

In this documentary, Jane Elliott meets with her class to talk about the classroom experiment about discrimination she performed 15 years earlier and the effects it had on their lives. In addition, Jane Elliott is seen giving this lesson to employees of the Iowa prison system.

An expanded edition of William Peters's classic study of the unique eye-color lesson in prejudice and discrimination taught by Iowa schoolteacher Jane Elliott. This new edition continues the story of Elliott and her sixteen third-graders of 1970, eleven of whom returned to their hometown in 1984 for a reunion with their former teacher. Peters reports on that meeting and its evidence that the long-ago lesson has had a profound and enduring effect on the students' lives and attitudes.

Not In Our Town is a documentary series and campaign that combines public television broadcasts with grassroots events, educational outreach and online activities to help communities battling hate talk to and learn from each other.

The Not In Our Town project was launched in 1995 with a national PBS special that told the story of how citizens of Billings, Montana joined forces to respond to hate crimes in their town. Their story helped create a new “model” for community response to bigotry and intolerance. Not In Our Town and its follow-up programs have been used in hundreds of communities during times of crisis.

Facing History and Ourselves has developed a face-to-face workshop on ostracism and bullying that uses the ostracism case study as its core content. In the workshop, participants read and respond to the voices of eighth grade students and one of their teachers as they talk about a social conflict among a group of friends that escalated into the ostracism of one of them. Their voices bring us inside their world and provoke questions about issues of inclusion and exclusion in adolescence and beyond. What is the role of young people and adults in preventing and responding to these kinds of incidents? What are the connections between these kinds of social issues facing students and the choices that teachers make in their classrooms and schools?

Follow an expedition to a remote cave in the Judean desert, first excavated by the famed Israeli archeologist Yigael Yadin in 1960-61. Yadin uncovered a cache of ancient documents, human skulls, and artifacts that shed light on a legendary revolt by Jews against the Roman Empire in the year 132. The uprising, led by Jewish patriot Shimon Bar-Kokhba, is said to have resulted in the Roman slaughter of 580,000 Jews. NOVA explores the last refuge of one group of Bar-Kokhba's followers with an historian whose bold theories have rocked the world of biblical archeology.

The Merry Wives of Windsor is a comedy by William Shakespeare, first published in 1602, though believed to have been written prior to 1597. It features the fat knight Sir John Falstaff, and is Shakespeare's only play to deal exclusively with contemporary Elizabethan era English middle class life. It has been adapted for the opera on occasions.

Genetic testing (also called DNA-based tests) is among the newest and most sophisticated of techniques used to test for genetic disorders which involves direct examination of the DNA molecule itself. Other genetic tests include biochemical tests for such gene products as enzymes and other proteins and for microscopic examination of stained or fluorescent chromosomes. Genetic tests are used for several reasons, including:

carrier screening, which involves identifying unaffected individuals who carry one copy of a gene for a disease that requires two copies for the disease to be expressed
preimplantation genetic diagnosis (see the side bar, Screening Embryos for Disease)
prenatal diagnostic testing
newborn screening
Genealogical DNA test (for genetic genealogy purposes)
presymptomatic testing for predicting adult-onset disorders such as Huntington's disease
presymptomatic testing for estimating the risk of developing adult-onset cancers and Alzheimer's disease
confirmational diagnosis of a symptomatic individual
forensic/identity testing

The Triangle Shirtwaist Factory fire in New York City on March 25, 1911, was the deadliest industrial disaster in the history of the city of New York and resulted in the fourth highest loss of life from an industrial accident in U.S. history. It was also the second deadliest disaster in New York City – after the burning of the General Slocum on June 15, 1904 – until the destruction of the World Trade Center 90 years later. The fire caused the deaths of 146 garment workers, who died from the fire, smoke inhalation, or falling to their deaths. Most of the victims were recent Jewish and Italian immigrant women aged sixteen to twenty-three; the oldest victim was 48, the youngest were two fourteen-year-old girls.

Because the managers had locked the doors to the stairwells and exits – a common practice at the time to prevent pilferage and unauthorized breaks – many of the workers who could not escape the burning building jumped from the eighth, ninth, and tenth floors to the streets below. The fire led to legislation requiring improved factory safety standards and helped spur the growth of the International Ladies' Garment Workers' Union, which fought for better working conditions for sweatshop workers.

The factory was located in the Asch Building, at 23-29 Washington Place, now known as the Brown Building, which has been designated a National Historic Landmark and a New York City landmark.

The Armenian Genocide, also known as the Armenian Holocaust, the Armenian Massacres and, by Armenians, as the Great Crime was the systematic killing of the Armenian population of the Ottoman Empire during and just after World War I. It was implemented through wholesale massacres and deportations, with the deportations consisting of forced marches under conditions designed to lead to the death of the deportees. The total number of resulting Armenian deaths is generally held to have been between 1 million and 1.5 million. Other ethnic groups were similarly attacked by the Ottoman Empire during this period, including Assyrians and Greeks, and some scholars consider those events to be part of the same policy of extermination.

It is widely acknowledged to have been one of the first modern genocides, as scholars point to the organized manner in which the killings were carried out to eliminate the Armenians, and it is the second most-studied case of genocide after the Holocaust. The word genocide was coined in order to describe these events.

The starting date of the genocide is conventionally held to be April 24, 1915, the day when Ottoman authorities arrested some 250 Armenian intellectuals and community leaders in Constantinople.

When a highly successful Mexican American Studies program at a high school in Tucson comes under fire for teaching ethnic chauvinism, teachers and students fight back. This modern civil rights struggle is born at the epicenter of the immigration debate in the age of identity politics.

The People Speak is a documentary feature film that uses dramatic and musical performances of the letters, diaries, and speeches of everyday Americans. The film gives voice to those who, by insisting on equality and justice, spoke up for social change throughout U.S. history and also illustrates the relevance of this to today's society.

The film is narrated by historian Howard Zinn and is based on his books A People's History of the United States and, with Anthony Arnove, Voices of a People's History of the United States.

The Life of Timon of Athens is a play by William Shakespeare about the legendary Athenian misanthrope Timon (and probably influenced by the eponymous philosopher, as well), generally regarded as one of his most obscure and difficult works. Originally grouped with the tragedies, it is generally considered such, but some scholars group it with the problem comedies.

Picturing United States History: An Interactive Resource for Teaching with Visual Evidence is a digital project based on the belief that visual materials are vital to understanding the American past. This website provides online "Lessons in Looking," a guide to Web resources, forums, essays, reviews, and classroom activities to help teachers incorporate visual evidence into their classrooms. The Picturing U.S. History site will also serve as a clearing house for teachers interested in incorporating visual documents into their U.S. history, American studies, American literature, or other humanities courses.

The invention of printing made maps much more widely available beginning in the 15th century. Maps were at first printed using carved wooden blocks (see above). Among the most important map makers of this period was Sebastian Münster in Basel (now Switzerland). His Geographia, published in 1540, became the new global standard for maps of the world.

Printing with engraved copper plates appeared in the 16th century and continued to be the standard until photographic techniques were developed. Major advances in cartography took place during the Age of Exploration in the 15th and 16th centuries. Map makers responded with navigation charts, which depicted coast lines, islands, rivers, harbors, and features of sailing interest. Compass lines and other navigation aids were included, new map projections were devised, and globes were constructed. Such maps and globes were held in great value for economic, military, and diplomatic purposes, and so were often treated as national or commercial secrets--classified or proprietary maps.

The first .whole-world maps began to appear in the early 16th century, following voyages by Columbus and others to the New World. The first true world map is generally credited to Martin Waldseemüller in 1507. This map utilized an expanded Ptolemaic projection and was the first map to use the name America for the New World.

The 1936 Summer Olympics, officially known as the Games of the XI Olympiad, was an international multi-sport event which was held in 1936 in Berlin, Germany. Berlin won the bid to host the Games over Barcelona, Spain on 26 April 1931, at the 29th IOC Session in Barcelona (two years before the Nazis came to power). It marked the second and final time that the International Olympic Committee would gather to vote in a city which was bidding to host those Games. The only other time this occurred was at the inaugural IOC Session in Paris, France, on 24 April 1894. Then, Athens, Greece and Paris, France were chosen to host the 1896 and 1900 Games, respectively.

To outdo the Los Angeles games in 1932, the Nazis built a brand new 100,000-seat track and field stadium, 6 gymnasiums, and many other smaller arenas. They also installed a closed-circuit television system, radio network that reached 41 countries, and many other forms of expensive high-tech electronic equipment. Filmmaker Leni Riefenstahl, a favorite of Adolf Hitler, was commissioned for $7 million by the German Olympic Committee to film the Games. Her film, entitled Olympia, introduced many of the techniques now common to the filming of sports.

The flute is a musical instrument of the woodwind family. Unlike woodwind instruments with reeds, a flute is an aerophone or reedless wind instrument that produces its sound from the flow of air across an opening. According to the instrument classification of Hornbostel-Sachs, flutes are categorized as edge-blown aerophones.

A musician who plays the flute can be referred to as a flute player, a flautist, a flutist, or less commonly a fluter.

Aside from the voice, flutes are the earliest known musical instruments. A number of flutes dating to about 40,000 to 35,000 years ago have been found in the Swabian Alb region of Germany. These flutes demonstrate that a developed musical tradition existed from the earliest period of modern human presence in Europe.

The War of 1812 was a military conflict fought between the forces of the United States of America and those of the British Empire. The Americans declared war in 1812 for several reasons, including trade restrictions due to Britain's ongoing war with France, the impressment of American merchant sailors into the Royal Navy, British support of American Indian tribes against American expansion, outrage over insults to national honour after humiliations on the high seas and possible American desire to annex Canada

Emily Elizabeth Dickinson (December 10, 1830 – May 15, 1886) was an American poet. Born in Amherst, Massachusetts, to a successful family with strong community ties, she lived a mostly introverted and reclusive life. After she studied at the Amherst Academy for seven years in her youth, she spent a short time at Mount Holyoke Female Seminary before returning to her family's house in Amherst. Thought of as an eccentric by the locals, she became known for her penchant for white clothing and her reluctance to greet guests or, later in life, even leave her room. Most of her friendships were therefore carried out by correspondence.

Although Dickinson was a prolific private poet, fewer than a dozen of her nearly eighteen hundred poems were published during her lifetime. The work that was published during her lifetime was usually altered significantly by the publishers to fit the conventional poetic rules of the time. Dickinson's poems are unique for the era in which she wrote; they contain short lines, typically lack titles, and often use slant rhyme as well as unconventional capitalization and punctuation. Many of her poems deal with themes of death and immortality, two recurring topics in letters to her friends.

The Organization for Economic Co-operation and Development (OECD) started an inter-governmental project in 2003 with the objective of providing ways to improve financial education and literacy standards through the development of common financial literacy principles. In March 2008, the OECD launched the International Gateway for Financial Education, which serves as a clearinghouse for financial education programs, information and research worldwide. In the UK, the alternative term “financial capability” is used by the state and its agencies: the Financial Services Authority (FSA) in the UK started a national strategy on financial capability in 2003. The US Government also established its Financial Literacy and Education Commission in 2003

All's Well That Ends Well is a play by William Shakespeare, originally classified as a comedy, though now often counted as one of his problem plays, so-called because they cannot be easily classified as tragedy or comedy. It was probably written in later middle part of Shakespeare's career, between 1601 and 1608, and was first published in the First Folio in 1623.

The name of the play comes from the proverb All's well that ends well, which means that problems do not matter so long as the outcome is good.

Candide, ou l'Optimisme is a French satire first published in 1759 by Voltaire, a philosopher of the Age of Enlightenment. The novella has been widely translated, with English versions titled Candide: or, All for the Best (1759); Candide: or, The Optimist (1762); and Candide: or, Optimism (1947). It begins with a young man, Candide, who is living a sheltered life in an Edenic paradise and being indoctrinated with Leibnizian optimism (or simply Optimism) by his mentor, Pangloss. The work describes the abrupt cessation of this lifestyle, followed by Candide's slow, painful disillusionment as he witnesses and experiences great hardships in the world. Voltaire concludes with Candide, if not rejecting optimism outright, advocating an enigmatic precept, "we must cultivate our garden", in lieu of the Leibnizian mantra of Pangloss, "all is for the best in the best of all possible worlds".

Candide is an operetta with music composed by Leonard Bernstein, based on the novella of the same name by Voltaire. The operetta was first performed in 1956 with a libretto by Lillian Hellman; but since 1974 it has been generally performed with a book by Hugh Wheeler which is more faithful to Voltaire's novel. The primary lyricist was the poet Richard Wilbur. Other contributors to the text were John Latouche, Dorothy Parker, Lillian Hellman, Stephen Sondheim, Leonard Bernstein, John Mauceri, and John Wells. Maurice Peress and Hershy Kay contributed orchestrations. Although unsuccessful at its premiere, Candide has now overcome the unenthusiastic reaction of early audiences and critics and achieved enormous popularity. It is very popular among major music schools as a student show because of the quality of its music and the opportunities it offers to student singers.

Pericles, Prince of Tyre is a play written (at least in part) by William Shakespeare and included in modern editions of his collected works despite some questions over its authorship, as it was not included in the First Folio. Many modern editors believe that Shakespeare is responsible for the main portion of the play after scene 9 that follows the story of Pericles and Marina, and that the first two acts, detailing the many voyages of Pericles, were written by a relatively untalented reviser or collaborator, possibly George Wilkins.

The Saint John's Bible is the first completely handwritten and illuminated Bible to have been commissioned by a Benedictine Abbey since the invention of the printing press.

Beginning in 1970, master calligrapher Donald Jackson expressed in media interviews his lifelong dream of creating an illuminated Bible. Following a Saint John's-sponsored calligraphy presentation at the Newberry Library in Chicago in 1995, Jackson discussed a handwritten Bible with Fr. Eric Hollas, OSB, former executive director of the Hill Monastic Manuscript Library at Saint John's University in Collegeville, Minnesota. Between 1996 and 1997, Saint John's explored the feasibility of the Bible project, Jackson created first samples, and theologians developed the illumination schema. The Saint John’s Bible was officially commissioned in 1998 and funding opportunities were launched. The public was introduced to the project in 1999 and production was completed in 2011, with the final word penned in May of 2011 and touch-up work completed by December of 2011.

The Saint John’s Bible is divided into seven volumes and is two feet tall by three feet wide when open. The Bible is made of vellum, with 160 illuminations, and has cost $4 million to produce. The version of the Bible used is the New Revised Standard Version Catholic Edition (NRSV-CE).

The scriptorium of The Saint John's Bible is located in Monmouth, Wales.

The Authorized Version, commonly known as the King James Version, King James Bible or KJV, is an English translation of the Christian Bible by the Church of England begun in 1604 and completed in 1611. First printed by the King's Printer Robert Barker, this was the third official translation into English. The first was the Great Bible commissioned by the Church of England in the reign of King Henry VIII, and the second was the Bishop's Bible of 1568. In January 1604, King James VI of Scotland and I of England convened the Hampton Court Conference where a new English version was conceived in response to the perceived problems of the earlier translations as detected by the Puritans, a faction within the Church of England.

James gave the translators instructions intended to guarantee that the new version would conform to the ecclesiology and reflect the episcopal structure of the Church of England and its belief in an ordained clergy. The translation was done by 47 scholars, all of whom were members of the Church of England. In common with most other translations of the period, the New Testament was translated from Greek, the Old Testament was translated from Hebrew text, while the Apocrypha were translated from the Greek and Latin. In the Book of Common Prayer (1662), the text of the Authorized Version replaced the text of the Great Bible – for Epistle and Gospel readings – and as such was authorised by Act of Parliament. By the first half of the 18th century, the Authorized Version was effectively unchallenged as the English translation used in Anglican and Protestant churches. Over the course of the 18th century, the Authorized Version supplanted the Latin Vulgate as the standard version of scripture for English speaking scholars.

Messiah is an English-language oratorio composed in 1741 by George Frideric Handel, with a scriptural text compiled by Charles Jennens from the King James Bible, and from the Psalms included with the Book of Common Prayer (which are worded slightly differently from their King James counterparts). It was first performed in Dublin on 13 April 1742, and received its London premiere nearly a year later. After an initially modest public reception the oratorio gained in popularity, eventually becoming one of the best-known and most frequently performed choral works in Western music.

Handel's reputation in England, where he had lived since 1713, had been established through his compositions of Italian opera. He turned to English oratorio in the 1730s, in response to changes in public taste; Messiah was his sixth work in this genre. Although its structure resembles that of conventional opera, it is not in dramatic form; there are no impersonations of characters and very little direct speech. Instead, Jennens's text is an extended reflection on Jesus Christ as Messiah, moving from the prophetic phrases of Isaiah and others, through the Incarnation, Passion and Resurrection of Christ to his ultimate glorification in heaven.

The Book of Psalms (Tiberian: Təhillîm; Modern: Tehillim, תְהִלִּים, or "praises"), commonly referred to simply as Psalms, is a book of the Hebrew Bible, the Christian Bible, and the Islamic Zabur. Taken together, its 150 poems "express virtually the full range of Israel's religious faith."

Each of the 150 Psalms are represented by a video based on that Psalm.
