CASE 463 - The space race

CASE 463 - Space race



The original Space Race was a 20th-century competition between two Cold War rivals, the Soviet Union (USSR) and the United States (US), for supremacy in spaceflight capability. In 1955, with both the United States and the Soviet Union building ballistic missiles that could be utilized to launch objects into space, the "starting line" was drawn for the Space Race. In separate announcements four days apart, both nations publicly announced that they would launch artificial Earth satellites by 1957 or 1958. On July 29, 1955, James C. Hagerty, president Dwight D. Eisenhower's press secretary, announced that the United States intended to launch "small Earth circling satellites" between July 1, 1957, and December 31, 1958, as part of their contribution to the International Geophysical Year (IGY). Four days later, at the Sixth Congress of International Astronautical Federation in Copenhagen, scientist Leonid I. Sedov spoke to international reporters at the Soviet embassy, and announced his country's intention to launch a satellite as well, in the "near future". On August 30, 1955, Korolev managed to get the Soviet Academy of Sciences to create a commission whose purpose was to beat the Americans into Earth orbit: this was the de facto start date for the Space Race. The Council of Ministers of the Soviet Union began a policy of treating development of its space program as a classified state secret.



Gagarin became a national hero of the Soviet Union and the Eastern Bloc, and a worldwide celebrity. Moscow and other cities in the USSR held mass demonstrations, the scale of which was second only to the World War II Victory Parade of 1945. April 12 was declared Cosmonautics Day in the USSR, and is celebrated today in Russia as one of the official "Commemorative Dates of Russia." In 2011, it was declared the International Day of Human Space Flight by the United Nations.



Human spaceflight after Apollo

In the 1970s, the United States began developing a new generation of reusable orbital spacecraft known as the Space Shuttle, and launched a range of unmanned probes. The USSR continued to develop space station technology with the Salyut program and Mir ('Peace' or 'World', depending on the context) space station, supported by Soyuz spacecraft. They developed their own large space shuttle under the Buran program. The USSR dissolved in 1991 and the remains of its space program mainly passed to Russia. The United States and Russia worked together in space with the Shuttle–Mir Program, and again with the International Space Station.

The Russian R-7 rocket family, which launched the first Sputnik at the beginning of the space race, is still in use today. It services the International Space Station (ISS) as the launcher for both the Soyuz and Progress spacecraft. It also ferries both Russian and American crews to and from the station.

CASE 462 - The different ages of human civilization



Africa provides a comprehensive and contigious time line of human development going back at least 7 million years. Africa, which developed the world's oldest human civilization, gave humanity the use of fire a million and half to two million years ago. It is the home of the first tools, astronomy, jewelry, fishing, mathematics, crops, art, use of pigments, cutting and other pointed instruments and animal domestication. In short Africa gave the world human civilization. Millions of years ago human life started in Africa, Australopithecus aphaeresis and Australopithecus africanus and Australopithecus robustus were all key rungs in the development of humanity. These fossils were found in East and South Africa (Azania). Some of the fossils may be as old as 5 million years. For example Australopithecus robustus fossils found in an East Turkana Kenya site were at least 4 million year old.

It is generally accepted that the Homo habilis were the first full fledge tool making ancestor of humans. The earliest archaeological evidence of toolmaking comes from the Koobi Fora section of East Turkana. These Homo habilis are believed to be at least 2.5 million years old. The name Homo habilis comes from the Leakeys. They found what they believed to be conclusive fossil evidence of the first humans in the Olduvai Gorge in Tanzania and gave these ancestors that name called Homo habilis.. The Olduvai Gorge Homo habilis existed at least a million and quarter years ago

Our knowledge of prehistory derives from surviving objects - the evidence of archaeology. History, by contrast, is based on documents. These various interconnections mean that history, civilization and writing all begin at the same time. That time is about 3100 BC.



The categorization of the past into discrete, quantified named blocks of time is called periodization. This is a list of such named time periods as defined in various fields of study. Major categorization systems include cosmological (time periods in the origin and evolution of the universe), geological (time periods in the origin and evolution of the Earth), anthropological (time periods in the origin and evolution of humans) and historical (written history).

The ingredients of civilization

Many different elements must come together before a human community develops to the level of sophistication commonly referred to as civilization. The first is the existence of settlements classifiable as towns or cities. This requires food production to be efficient enough for a large minority of the community to be engaged in more specialized activities - such as the creation of imposing buildings or works of art, the practice of skilled warfare, and above all the administration of a centralized bureaucracy capable of running the machinery of state.

CASE 461 - The history of Greenland

CASE 461 - The history of Greenland



The history of Greenland is a history of life under extreme Arctic conditions: currently, an ice cap covers about 80 percent of the island, restricting human activity largely to the coasts. The first humans are thought to have arrived in Greenland around 2500 BC. Their descendants apparently died out and were succeeded by several other groups migrating from continental North America. There has been no evidence discovered that Greenland was known to Europeans until the 10th century, when Icelandic Vikings settled on its southwestern coast, which seems to have been uninhabited when they arrived. The ancestors of the Inuit Greenlanders who live there today appear to have migrated there later, around 1200 AD, from northwestern Greenland. While the Inuit survived in the icy world of the Little Ice Age, the early Norse settlements along the southwestern coast disappeared, leaving the Inuit as the only inhabitants of the island for several centuries. During this time, Denmark-Norway, apparently believing the Norse settlements had survived, continued to claim sovereignty over the island despite the lack of any contact between the Norse Greenlanders and their Scandinavian brethren. In 1721, aspiring to become a colonial power, Denmark-Norway sent a missionary expedition to Greenland with the stated aim of reinstating Christianity among descendants of the Norse Greenlanders who may have reverted to paganism. When the missionaries found no descendants of the Norse Greenlanders, they baptized the Inuit Greenlanders they found living there instead. Denmark-Norway then developed trading colonies along the coast and imposed a trade monopoly and other colonial privileges on the area.



During World War II, when Germany invaded Denmark, Greenlanders became socially and economically less connected to Denmark and more connected to the United States and Canada. After the war, Denmark resumed control of Greenland and in 1953 converted its status from colony to overseas amt (county). Although Greenland is still a part of the Kingdom of Denmark, it has enjoyed home rule since 1979. In 1985, the island decided to leave the European Union, which it had joined as a part of Denmark in 1973. From 1948 to 1950, the Greenland Commission studied the conditions on the island, seeking to address its isolation, unequal laws, and economic stagnation. In the end, the Royal Greenland Trading Department's monopolies were finally removed. In 1953, Greenland was raised from the status of colony to that of an autonomous province or constituent country of the Danish Realm. Despite its small population of 50000 to 55000 people, it was provided nominal representation in the Danish Folketing.



Greenland home rule

Greenland's minimal representation in the Folketing meant that despite 70.3% of Greenlanders rejecting entry into the European Common Market (EEC), it was pulled in along with Denmark in 1973. Fears that the customs union would allow foreign firms to compete and overfish its waters were quickly realized and the local parties began to push strongly for increased autonomy. The Folketing approved devolution in 1978 and the next year enacted home rule under a local Landsting. On 23 February 1982, a bare majority (53%) of Greenland's population voted to leave the EEC, a process which lasted until 1985. Greenland Home Rule has become increasingly Greenlandized, rejecting Danish and avoiding regional dialects to standardize the country under the language and culture of the Kalaallit (West Greenland Inuit). The capital Godthåb was renamed Nuuk in 1979; a local flag was adopted in 1985; the Danish KGH became the locally administered Kalaallit Niuerfiat (now KNI A/S) in 1986. Following a successful referendum on self-government in 2008, the local parliament's powers were expanded and Danish was removed as an official language in 2009.

International relations are now largely, but not entirely, also left to the discretion of the home rule government. After leaving the EEC, Greenland signed a special treaty with it, granting it special access to the market as a constituent country of Denmark, which remains a member. Greenland is also a member of several small organizations along with Iceland, the Faroes, and the Inuit populations of Canada and Russia. It was one of the founders of the environmental Arctic Council in 1996. The US military bases on the island remain a major issue, with some politicians pushing for renegotiation of the 1951 US–Denmark treaty by the Home Rule government. The 1999–2003 Commission on Self-Governance even proposed that Greenland should aim at Thule Air Base's removal from American authority and operation under the aegis of the United Nations.[

CASE 460 - The history of music - part 4 / The 1950's

CASE 460 - The history of music - part 4 / The 1950's



In the First World, rock and roll, doo-wop, pop, jazz, swing, rhythm and blues, blues, country and rockabilly dominated and defined the decade's music. Rock and roll dominated popular music in the later half of the 1950s. It evolved in the United States during the late 1940s and early 1950s, and quickly spread to much of the rest of the world. Its immediate origins lay in a mixing together of various black musical genres of the time, including rhythm and blues and gospel music; with country and western and Pop. In 1951, Cleveland, Ohio disc jockey Alan Freed began playing rhythm and blues music for a multi-racial audience and is credited with first using the phrase "rock and roll" to describe the music.

The 1950s saw the growth in popularity of the electric guitar (developed and popularized by Les Paul). Paul's hit records like "How High the Moon", and "The World Is Waiting for the Sunrise", helped lead to the development of a specifically rock and roll style of playing of such exponents as Chuck Berry, Link Wray, and Scotty Moore. Chuck Berry, who is considered to be one of the pioneers of Rock and roll music, refined and developed the major elements that made rock and roll distinctive, focusing on teen life and introducing guitar solos and showmanship that would be a major influence on subsequent rock music. Artists such as Chuck Berry, Bo Diddley, Fats Domino, Little Richard, Jerry Lee Lewis, Big Joe Turner, and Gene Vincent released the initial rhythm and blues-influenced early rock and roll hits. Rock and roll forerunners in the popular music field included Johnnie Ray, The Crew-Cuts, The Fontane Sisters, and Les Paul and Mary Ford. The Rock and Roll Era is generally dated from 25 March 1955 premiere of the motion picture, "The Blackboard Jungle". This film’s use of Bill Haley and His Comets' "(We’re Gonna) Rock Around the Clock" over its opening credits, caused a national sensation when teenagers started dancing in the aisles. Pat Boone became one of the most successful artists of the 50s with his heavily Pop-influenced "covers" of R&B hits like "Two Hearts, Two Kisses (Make One Love)", "Ain't That a Shame", and "At My Front Door (Crazy Little Mama)". Boone's traditional pop approach to rock and roll, coupled with his All-American, clean-cut image helped bring the new sound to a much wider audience. Elvis Presley, who began his career in the mid-1950s, soon became the leading figure of the newly popular sound of rock and roll with a series of network television appearances, motion pictures, and chart-topping records. His energized interpretations of songs, many from African American sources, and his uninhibited performance style made him enormously popular—and controversial during that period. Boone and Presley's styles/images represented opposite ends of the burgeoning musical form, which competed with one another throughout the remainder of the decade.

Rock & roll

Rock and roll dominated popular music in the later half of the 1950s. It evolved in the United States during the late 1940s and early 1950s, and quickly spread to much of the rest of the world. Its immediate origins lay in a mixing together of various black musical genres of the time, including rhythm and blues and gospel music; with country and western and Pop. In 1951, Cleveland, Ohio disc jockey Alan Freed began playing rhythm and blues music for a multi-racial audience, and is credited with first using the phrase "rock and roll" to describe the music. The 1950s saw the growth in popularity of the electric guitar (developed and popularized by Les Paul). Paul's hit records like "How High the Moon", and "The World Is Waiting for the Sunrise", helped lead to the development of a specifically rock and roll style of playing of such exponents as Chuck Berry, Link Wray, and Scotty Moore. Chuck Berry, who is considered to be one of the pioneers of Rock and roll music, refined and developed the major elements that made rock and roll distinctive, focusing on teen life and introducing guitar solos and showmanship that would be a major influence on subsequent rock music.

Classic pop

Popular music dominated the charts for the first half of the decade. Vocal-driven classic pop replaced big band/swing at the end of World War II, although it often used orchestras to back the vocalists. 1940s style Crooners vied with a new generation of big voiced singers, many drawing on Italian Canto Bella traditions. Mitch Miller, A&R man at the era's most successful label, Columbia Records, set the tone for the development of popular music well into the middle of the decade. Miller integrated country, Western, rhythm & blues, and folk music into the musical mainstream, by having many of his label's biggest artists record them in a style that corresponded to Pop traditions. Miller often employed novel and ear-catching arrangements featuring classical instruments (whooping french horns, harpsichord), or sound effects (whip cracks). He approached each record as a miniature story, often "casting" the vocalist according to type.

R&B

In 1951, Little Richard Penniman began recording for RCA Records in the late-1940s jump blues style of Joe Brown and Billy Wright. However, it wasn't until he prepared a demo in 1954, that caught the attention of Specialty Records, that the world would start to hear his new, uptempo, funky rhythm and blues that would catapult him to fame in 1955 and help define the sound of rock and roll. A rapid succession of rhythm-and-blues hits followed, beginning with "Tutti Frutti" and "Long Tall Sally", which would influence performers such as James Brown, Elvis Presley, and Otis Redding. At the urging of Leonard Chess at Chess Records, Chuck Berry had reworked a country fiddle tune with a long history, entitled "Ida Red". The resulting "Maybellene" was not only a #3 hit on the R&B charts in 1955, but also reached into the top 30 on the pop charts.

Stax Records was founded in 1957 as Satellite Records. The label was a major factor in the creation of the Southern soul and Memphis soul styles.

In 1959, two black-owned record labels, one of which would become hugely successful, made their debut: Sam Cooke's Sar, and Berry Gordy's Motown Records.

Blues

Ray Charles

Blues had a huge influence on mainstream American popular music in the 1950s with the enthusiastic playing styles of popular musicians like Bo Diddley and Chuck Berry, departed from the melancholy aspects of blues and influenced Rock and roll music. Ray Charles and Fats Domino help bring blues into the popular music scene. Domino provides a boogie-woogie style that heavily influences rock 'n' roll.

Country music

Country music stars in the early 1950s included Hank Williams, Patsy Cline, Bill Monroe, Eddy Arnold, Gene Autry, Tex Ritter, Jim Reeves, Tennessee Ernie Ford, Chet Atkins and Kitty Wells. Wells' 1952 hit "It Wasn't God Who Made Honky Tonk Angels" became the first single by a solo female artist to top the U.S. country charts. "It Wasn't God ... " was a landmark single in several ways; it began a trend of "answer" songs, or songs written and recorded in response to (or to counterpoint) a previously popular song – in this case, "The Wild Side of Life" by Hank Thompson – and for Wells, began a trend of female singers who defied the typical stereotype of being submissive to men and putting up with their oft-infidel ways, both in their personal lives and in their songs.
