The Dead Past
"The Dead Past" is a science fiction short story by American writer Isaac Asimov, first published in the April 1956 issue of ''Astounding Science Fiction''. It was later collected in ''Earth Is Room Enough'' (1957) and ''The Best of Isaac Asimov'' (1973), and adapted into an episode of the science-fiction television series ''Out of the Unknown''. Its pattern is that of dystopian fiction, but of a subtly nuanced flavor. It is considered by some people to be one of his best short stories. Plot summary Asimov extrapolates the twin trends towards centralization of academic research and scientific specialization, to portray a world in which state control of scientific research is overseen by a vast bureaucracy, and scholars are effectively forbidden from working outside their narrow field of specialization. Working innocently under these constraints is Arnold Potterley, a professor of ancient history. Potterley, an expert on ancient Carthage, wishes to gain access to the chronoscope, ...

Dystopia
A dystopia (from Ancient Greek δυσ- "bad, hard" and τόπος "place"; alternatively cacotopiaCacotopia (from κακός ''kakos'' "bad") was the term used by Jeremy Bentham in his 1818 Plan of Parliamentary Reform (Works, vol. 3, p. 493). or simply anti-utopia) is a speculated community or society that is undesirable or frightening. It is often treated as an Opposite (semantics), antonym of ''utopia'', a term that was coined by Sir Thomas More and figures as the title of his best known work, published in 1516, which created a blueprint for an ideal society with minimal crime, violence and poverty. The relationship between utopia and dystopia is in actuality not one simple opposition, as many utopian elements and components are found in dystopias as well, and ''vice versa''. Dystopias are often characterized by rampant fear or distress , tyrannical governments, environmental disaster, or other characteristics associated with a cataclysmic decline in society.

Transistor
upright=1.4, gate (G), body (B), source (S) and drain (D) terminals. The gate is separated from the body by an insulating layer (pink). A transistor is a semiconductor device used to Electronic amplifier, amplify or electronic switch, switch electrical signals and electrical power, power. The transistor is one of the basic building blocks of modern electronics. It is composed of semiconductor material, usually with at least three terminals for connection to an electronic circuit. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Some transistors are packaged individually, but many more are found embedded in integrated circuits. Austro-Hungarian physicist Julius Edgar Lilienfeld proposed the concept of a field-effect transistor in 1926, but it was not possible to actually constru ...

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 ...

Nineteen Eighty-Four
''Nineteen Eighty-Four'' (also stylised as ''1984'') is a dystopian social science fiction novel and cautionary tale written by the English writer George Orwell. It was published on 8 June 1949 by Secker & Warburg as Orwell's ninth and final book completed in his lifetime. Thematically, it centres on the consequences of totalitarianism, mass surveillance and repressive regimentation of people and behaviours within society. Orwell, a democratic socialist, modelled the authoritarian state in the novel on Stalinist Russia and Nazi Germany. More broadly, the novel examines the role of truth and facts within societies and the ways in which they can be manipulated. The story takes place in an imagined future in the year 1984, when much of the world is in perpetual war. Great Britain, now known as Airstrip One, has become a province of the totalitarian superstate Oceania, which is led by Big Brother, a dictatorial leader supported by an intense cult of personality manufactured by ...

Brave New World
''Brave New World'' is a dystopian novel by English author Aldous Huxley, written in 1931 and published in 1932. Largely set in a futuristic World State, whose citizens are environmentally engineered into an intelligence-based social hierarchy, the novel anticipates huge scientific advancements in reproductive technology, sleep-learning, psychological manipulation and classical conditioning that are combined to make a dystopian society which is challenged by only a single individual: the story's protagonist. Huxley followed this book with a reassessment in essay form, ''Brave New World Revisited'' (1958), and with his final novel, ''Island'' (1962), the utopian counterpart. This novel is often compared to George Orwell's ''Nineteen Eighty-Four'' (1949). In 1999, the Modern Library ranked ''Brave New World'' at number 5 on its list of the 100 best English-language novels of the 20th century. This ranking was by thModern Library Editorial Boardof authors. In 2003, Robert McCr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fahrenheit 451
''Fahrenheit 451'' is a 1953 dystopian novel by American writer Ray Bradbury. Often regarded as one of his best works, ''Fahrenheit 451'' presents an American society where books have been personified and outlawed and "firemen" burn any that are found. The novel follows Guy Montag, a fireman who becomes disillusioned with his role of censoring literature and destroying knowledge, eventually quitting his job and committing himself to the preservation of literary and cultural writings. ''Fahrenheit 451'' was written by Bradbury during the Second Red Scare and the McCarthy era, who was inspired by the book burnings in Nazi Germany and by ideological repression in the Soviet Union. Bradbury's claimed motivation for writing the novel has changed multiple times. In a 1956 radio interview, Bradbury said that he wrote the book because of his concerns about the threat of burning books in the United States. In later years, he described the book as a commentary on how mass media reduces ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Neutrino
A neutrino ( ; denoted by the Greek letter ) is a fermion (an elementary particle with spin of ) that interacts only via the weak interaction and gravity. The neutrino is so named because it is electrically neutral and because its rest mass is so small ('' -ino'') that it was long thought to be zero. The rest mass of the neutrino is much smaller than that of the other known elementary particles excluding massless particles. The weak force has a very short range, the gravitational interaction is extremely weak due to the very small mass of the neutrino, and neutrinos do not participate in the strong interaction. Thus, neutrinos typically pass through normal matter unimpeded and undetected. Weak interactions create neutrinos in one of three leptonic flavors: electron neutrinos muon neutrinos (), or tau neutrinos (), in association with the corresponding charged lepton. Although neutrinos were long believed to be massless, it is now known that there are three discrete ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
