Science-fiction
Science fiction (sometimes shortened to Sci-Fi or SF) is a genre of speculative fiction which typically deals with imaginative and futuristic concepts such as advanced science and technology, space exploration, time travel, parallel universes, extraterrestrial life, sentient artificial intelligence, cybernetics, certain forms of immortality (like mind uploading), and the singularity. Science fiction predicted several existing inventions, such as the atomic bomb, robots, and borazon, whose names entirely match their fictional predecessors. In addition, science fiction might serve as an outlet to facilitate future scientific and technological innovations. Science fiction can trace its roots to ancient mythology. It is also related to fantasy, horror, and superhero fiction and contains many subgenres. Its exact definition has long been disputed among authors, critics, scholars, and readers. Science fiction, in literature, film, television, and other media, has beco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Science Fiction Film
Science fiction (or sci-fi) is a film genre that uses speculative, fictional science-based depictions of phenomena that are not fully accepted by mainstream science, such as extraterrestrial lifeforms, spacecraft, robots, cyborgs, interstellar travel, time travel, or other technologies. Science fiction films have often been used to focus on political or social issues, and to explore philosophical issues like the human condition. The genre has existed since the early years of silent cinema, when Georges Melies' '' A Trip to the Moon'' (1902) employed trick photography effects. The next major example (first in feature length in the genre) was the film ''Metropolis'' (1927). From the 1930s to the 1950s, the genre consisted mainly of low-budget B movies. After Stanley Kubrick's landmark '' 2001: A Space Odyssey'' (1968), the science fiction film genre was taken more seriously. In the late 1970s, big-budget science fiction films filled with special effects became popular wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parallel Universes In Fiction
A parallel universe, also known as a parallel dimension, alternate universe, or alternate reality, is a hypothetical self-contained plane of existence, co-existing with one's own. The sum of all potential parallel universes that constitute reality is often called a " multiverse". While the four terms are generally synonymous and can be used interchangeably in most cases, there is sometimes an additional connotation implied with the term "alternate universe/reality" that implies that the reality is a variant of our own, with some overlap with the similarly named alternate history. Fiction has long borrowed an idea of "another world" from myth, legend and religion. Heaven, Hell, Olympus, and Valhalla are all "alternative universes" different from the familiar material realm. Plato reflected deeply on the parallel realities, resulting in Platonism, in which the upper reality is perfect while the lower earthly reality is an imperfect shadow of the heavenly. The concept is als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Technological Singularity
The technological singularity—or simply the singularity—is a hypothetical future point in time at which technological growth becomes uncontrollable and irreversible, resulting in unforeseeable changes to human civilization. According to the most popular version of the singularity hypothesis, I.J. Good's intelligence explosion model, an upgradable intelligent agent will eventually enter a "runaway reaction" of self-improvement cycles, each new and more intelligent generation appearing more and more rapidly, causing an "explosion" in intelligence and resulting in a powerful superintelligence that qualitatively far surpasses all human intelligence.Vinge, Vernor"The Coming Technological Singularity: How to Survive in the Post-Human Era", in ''Vision-21: Interdisciplinary Science and Engineering in the Era of Cyberspace'', G. A. Landis, ed., NASA Publication CP-10129, pp. 11–22, 1993. The first person to use the concept of a "singularity" in the technological context was John v ...

Time Travel
Time travel is the concept of movement between certain points in time, analogous to movement between different points in space by an object or a person, typically with the use of a hypothetical device known as a time machine. Time travel is a widely recognized concept in philosophy and fiction, particularly science fiction. The idea of a time machine was popularized by H. G. Wells' 1895 novel '' The Time Machine''. It is uncertain if time travel to the past is physically possible, and such travel, if at all feasible, may give rise to questions of causality. Forward time travel, outside the usual sense of the perception of time, is an extensively observed phenomenon and well-understood within the framework of special relativity and general relativity. However, making one body advance or delay more than a few milliseconds compared to another body is not feasible with current technology. As for backward time travel, it is possible to find solutions in general relativity that al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Definitions Of Science Fiction
There have been many attempts at defining science fiction. This is a list of definitions that have been offered by authors, editors, critics and fans over the years since science fiction became a genre. Definitions of related terms such as "science fantasy", "speculative fiction", and "fabulation" are included where they are intended as definitions of aspects of science fiction or because they illuminate related definitions—see e.g. Robert Scholes's definitions of "fabulation" and "structural fabulation" below. Some definitions of sub-types of science fiction are included, too; for example see David Ketterer's definition of "philosophically-oriented science fiction". In addition, some definitions are included that define, for example, a science fiction story, rather than science fiction itself, since these also illuminate an underlying definition of science fiction. ''The Encyclopedia of Science Fiction'', edited by John Clute and Peter Nicholls, contains an extensive discu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Existing Technologies Predicted In Science Fiction
This list of existing technologies predicted in science fiction includes every medium, mainly literature and film. In 1964 Soviet engineer and writer Genrikh Altshuller made the first attempt to catalogue science fiction technologies of the time. Alongside first prediction of a particular technology, the list may include all subsequent works mentioning it until its invention. The list includes technologies that were first posited in non-fiction works before their appearance in science fiction and subsequent invention, such as ion thruster. To avoid repetitions, the list excludes film adaptations of prior literature containing the same predictions, such as "The Minority Report". The list also excludes emerging technologies that are not widely available. The titles of non-English works are given in English. The names of some modern inventions (atomic bomb, credit card, robot, space station and borazon) exactly match their fictional predecessors. A few works correctly predicted the ye ...

Science
Science is a systematic endeavor that Scientific method, builds and organizes knowledge in the form of Testability, testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 Common Era, BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the Universe, physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of History of science in classical antiquity, Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the ...

Technology
Technology is the application of knowledge to reach practical goals in a specifiable and Reproducibility, reproducible way. The word ''technology'' may also mean the product of such an endeavor. The use of technology is widely prevalent in medicine, science, Industry (economics), industry, communication, transportation, and daily life. Technologies include physical objects like Kitchen utensil, utensils or machines and intangible Tool, tools such as software. Many technological advancements have led to societal changes. The earliest known technology is the stone tool, used in the Prehistory, prehistoric era, followed by Control of fire by early humans, fire use, which contributed to the Brain size, growth of the human brain and the development of language in the Pleistocene, Ice Age. The invention of the wheel in the Bronze Age enabled wider travel and the creation of more complex machines. Recent technological developments, including the printing press, the telephone, and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extraterrestrials In Fiction
An extraterrestrial or alien is any extraterrestrial lifeform; a lifeform that did not originate on Earth. The word ''extraterrestrial'' means "outside Earth". The first published use of ''extraterrestrial'' as a noun occurred in 1956, during the Golden Age of Science Fiction. Extraterrestrials are a common theme in modern science-fiction, and also appeared in much earlier works such as the second-century parody ''True History'' by Lucian of Samosata. Gary Westfahl writes: History Pre-modern Cosmic pluralism, the assumption that there are many inhabited worlds beyond the human sphere predates modernity and the development of the heliocentric model and is common in mythologies worldwide. The 2nd century writer of satires, Lucian, in his ''True History'' claims to have visited the moon when his ship was sent up by a fountain, which was peopled and at war with the people of the Sun over colonisation of the Morning Star. Other worlds are depicted in such early works as the 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artificial Intelligence
Artificial intelligence (AI) is intelligence—perceiving, synthesizing, and inferring information—demonstrated by machines, as opposed to intelligence displayed by animals and humans. Example tasks in which this is done include speech recognition, computer vision, translation between (natural) languages, as well as other mappings of inputs. The ''Oxford English Dictionary'' of Oxford University Press defines artificial intelligence as: the theory and development of computer systems able to perform tasks that normally require human intelligence, such as visual perception, speech recognition, decision-making, and translation between languages. AI applications include advanced web search engines (e.g., Google), recommendation systems (used by YouTube, Amazon and Netflix), understanding human speech (such as Siri and Alexa), self-driving cars (e.g., Tesla), automated decision-making and competing at the highest level in strategic game systems (such as chess and G ...

Borazon
Borazon is a brand name of a cubic form of boron nitride (cBN). Its color ranges from black to brown and gold, depending on the chemical bond. It is one of the hardest known materials, along with various forms of diamond and kinds of boron nitride. Borazon is a crystal created by heating equal quantities of boron and nitrogen at temperatures greater than 1800 °C (3300 °F) at 7 GPa (1 million lbf/in2). Borazon was first produced in 1957 by Robert H. Wentorf, Jr., a physical chemist working for the General Electric Company. In 1969, General Electric adopted the name Borazon as its trademark for the material. The trademark is now owned by Diamond Innovations, doing business aHyperion Materials & Technologies, Inc. and Borazon is manufactured only by Hyperion Materials & Technologies. Uses and production Borazon has a number of uses , such as: cutting tools, dies, punches, shears, knives, saw blades, bearing rings, needles, rollers, spacers, balls, pump, compr ...

Literature
Literature is any collection of written work, but it is also used more narrowly for writings specifically considered to be an art form, especially prose fiction, drama, and poetry. In recent centuries, the definition has expanded to include oral literature, much of which has been transcribed. Literature is a method of recording, preserving, and transmitting knowledge and entertainment, and can also have a social, psychological, spiritual, or political role. Literature, as an art form, can also include works in various non-fiction genres, such as biography, diaries, memoir, letters, and the essay. Within its broad definition, literature includes non-fictional books, articles or other printed information on a particular subject.''OED'' Etymologically, the term derives from Latin ''literatura/litteratura'' "learning, a writing, grammar," originally "writing formed with letters," from ''litera/littera'' "letter". In spite of this, the term has also been applied to spoken or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
