The Martian Way
''The Martian Way'' is a science fiction novella by American writer Isaac Asimov. It was first published in the November 1952 issue of ''Galaxy Science Fiction'' and reprinted in the collections '' The Martian Way and Other Stories'' (1955), '' The Best of Isaac Asimov'' (1973), and '' Robot Dreams'' (1986). It was also included in '' The Science Fiction Hall of Fame, Volume Two'' (1973) after being voted one of the best novellas up to 1965. There were originally no female characters in "The Martian Way", but ''Galaxy'' editor H. L. Gold insisted that one be included. Asimov complied by giving Richard Swenson a shrewish wife. It was not what Gold had in mind, but he accepted the story anyway. When Asimov wrote "The Martian Way" in 1952, it was thought that the fragments making up Saturn's rings might be over a mile in diameter. It is now known that none of the ring fragments is more than a few meters in diameter. The final journey back to Mars is described to be under constan ...

Mars
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, only being larger than Mercury. In the English language, Mars is named for the Roman god of war. Mars is a terrestrial planet with a thin atmosphere (less than 1% that of Earth's), and has a crust primarily composed of elements similar to Earth's crust, as well as a core made of iron and nickel. Mars has surface features such as impact craters, valleys, dunes and polar ice caps. It has two small and irregularly shaped moons, Phobos and Deimos. Some of the most notable surface features on Mars include Olympus Mons, the largest volcano and highest known mountain in the Solar System and Valles Marineris, one of the largest canyons in the Solar System. The Borealis basin in the Northern Hemisphere covers approximately 40% of the planet and may be a large impact feature. Days and seasons on Mars are comparable to those of Earth, as the planets have a similar rotation period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manifest Destiny
Manifest destiny was a cultural belief in the 19th-century United States that American settlers were destined to expand across North America. There were three basic tenets to the concept: * The special virtues of the American people and their institutions * The mission of the United States to redeem and remake the West in the image of the agrarian East * An irresistible destiny to accomplish this essential duty Historians have emphasized that "manifest destiny" was always contested; many endorsed the idea, but the large majority of Whigs and many prominent Americans (such as Abraham Lincoln and Ulysses S. Grant) rejected the concept. Historian Daniel Walker Howe writes, "American imperialism did not represent an American consensus; it provoked bitter dissent within the national polity while the ''Whigs'' saw America's moral mission as one of democratic example rather than conquest. The term was used by the then-Democrats in the 1840s to justify the Mexican–American Wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
In Memory Yet Green
Isaac Asimov (–1992) wrote three volumes of autobiography. ''In Memory Yet Green'' (1979) and ''In Joy Still Felt'' (1980) were a two-volume work, covering his life up to 1978. The third volume, ''I. Asimov: A Memoir'' (1994), published after his death, was not a sequel but a new work which covered his whole life. This third book won a Hugo Award. Before writing these books, Asimov also published three anthologies of science fiction stories which contained autobiographical accounts of his life in the introductions to the stories: ''The Early Asimov'' (1972), '' Before the Golden Age'' (1974), and '' Buy Jupiter and Other Stories'' (1975). Books ''The Early Asimov, or, Eleven Years of Trying'' ( Doubleday, 1972) is a collection of almost all of the published short stories Asimov wrote during the first eleven years of his career, 1938 to 1949, other than his robots and ''Foundation'' series of stories (and his first story, " Marooned off Vesta"), which had already been colle ...

House Un-American Activities Committee
The House Committee on Un-American Activities (HCUA), popularly dubbed the House Un-American Activities Committee (HUAC), was an investigative United States Congressional committee, committee of the United States House of Representatives, created in 1938 to investigate alleged disloyalty and subversive activities on the part of private citizens, public employees, and those organizations suspected of having either Fascism, fascist or Communism, communist ties. It became a standing (permanent) committee in 1945, and from 1969 onwards it was known as the House Committee on Internal Security. When the House abolished the committee in 1975, its functions were transferred to the United States House Committee on the Judiciary, House Judiciary Committee. The committee's anti-communist investigations are often associated with McCarthyism, although Joseph McCarthy himself (as a U.S. Senator) had no direct involvement with the House committee.

Joseph McCarthy
Joseph Raymond McCarthy (November 14, 1908 – May 2, 1957) was an American politician who served as a Republican United States Senate, U.S. Senator from the state of Wisconsin from 1947 until his death in 1957. Beginning in 1950, McCarthy became the most visible public face of a period in the United States in which Cold War tensions fueled fears of widespread Communism, communist Subversion (politics), subversion. He is known for alleging that numerous communists and Soviet Union, Soviet spies and sympathizers had infiltrated the United States federal government, universities, film industry, and elsewhere. Ultimately, he was censured for refusing to cooperate with, and abusing members of, the committee established to investigate whether or not he should be censured. The term "McCarthyism", coined in 1950 in reference to McCarthy's practices, was soon applied to similar anti-communism, anti-communist activities. Today, the term is used more broadly to mean demagogy, demagog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terraforming
Terraforming or terraformation ("Earth-shaping") is the hypothetical process of deliberately modifying the atmosphere, temperature, surface topography or ecology of a planet, moon, or other body to be similar to the environment of Earth to make it habitable for humans to live on. The concept of terraforming developed from both science fiction and actual science. Carl Sagan, an astronomer, proposed the planetary engineering of Venus in 1961, which is considered one of the first accounts of the concept. The term was coined by Jack Williamson in a science-fiction short story ("Collision Orbit") published in 1942 in ''Astounding Science Fiction'', although terraforming in popular culture may predate this work. Even if the environment of a planet could be altered deliberately, the feasibility of creating an unconstrained planetary environment that mimics Earth on another planet has yet to be verified. While Venus, Earth, Mars, and even the Moon have been studied in relation to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
McCarthyism
McCarthyism is the practice of making false or unfounded accusations of subversion and treason, especially when related to anarchism, communism and socialism, and especially when done in a public and attention-grabbing manner. The term originally referred to the controversial practices and policies of U.S. Senator Joseph McCarthy, and has its origins in the period in the United States known as the Second Red Scare, lasting from the late 1940s through the 1950s. It was characterized by heightened political repression and persecution of left-wing individuals, and a campaign spreading fear of alleged communist and socialist influence on American institutions and of espionage by Soviet agents. After the mid-1950s, McCarthyism began to decline, mainly due to Joseph McCarthy's gradual loss of public popularity and credibility after several of his accusations were found to be false, and sustained opposition from the U.S. Supreme Court led by Chief Justice Earl Warren on human rights ...

Solar System
The Solar System Capitalization of the name varies. The International Astronomical Union, the authoritative body regarding astronomical nomenclature, specifies capitalizing the names of all individual astronomical objects but uses mixed "Solar System" and "solar system" structures in theinaming guidelines document. The name is commonly rendered in lower case ('solar system'), as, for example, in the ''Oxford English Dictionary'' an''Merriam-Webster's 11th Collegiate Dictionary''. is the gravitationally bound system of the Sun and the objects that orbit it. It formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. The vast majority (99.86%) of the system's mass is in the Sun, with most of the remaining mass contained in the planet Jupiter. The four inner system planets— Mercury, Venus, Earth and Mars—are terrestrial planets, being composed primarily of rock and metal. The four giant planets of the outer system are ...

Rings Of Saturn
The rings of Saturn are the most extensive ring system of any planet in the Solar System. They consist of countless small particles, ranging in size from micrometers to meters, that orbit around Saturn. The ring particles are made almost entirely of water ice, with a trace component of rocky material. There is still no consensus as to their mechanism of formation. Although theoretical models indicated that the rings were likely to have formed early in the Solar System's history, newer data from '' Cassini'' suggested they formed relatively late. Although reflection from the rings increases Saturn's brightness, they are not visible from Earth with unaided vision. In 1610, the year after Galileo Galilei turned a telescope to the sky, he became the first person to observe Saturn's rings, though he could not see them well enough to discern their true nature. In 1655, Christiaan Huygens was the first person to describe them as a disk surrounding Saturn. The concept that Saturn's r ...

Saturn
Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius of about nine and a half times that of Earth. It has only one-eighth the average density of Earth; however, with its larger volume, Saturn is over 95 times more massive. Saturn's interior is most likely composed of a core of iron–nickel alloy, iron–nickel and rock (silicon and oxygen compounds). Its core is surrounded by a deep layer of metallic hydrogen, an intermediate layer of liquid hydrogen and liquid helium, and finally, a gaseous outer layer. Saturn has a pale yellow hue due to ammonia crystals in its upper atmosphere. An electrical current within the metallic hydrogen layer is thought to give rise to Saturn's planetary magnetic field, which is weaker than Earth's, but which has a magnetic moment 580 times that of Earth due to Saturn's larger size. Saturn's magnetic field strength is around one-twentieth of Jupiter's. The out ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
