British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law is the best known and most widely cited. They are part of his ideas in his extensive writings about the future.
Hard science fiction is a category of science fiction characterized by concern for scientific accuracy and logic. The term was first used in print in 1957 by P. Schuyler Miller in a review of John W. Campbell's Islands of Space in the November issue of Astounding Science Fiction. The complementary term soft science fiction, formed by analogy to the popular distinction between the "hard" (natural) and "soft" (social) sciences, first appeared in the late 1970s. Though there are examples generally considered as "hard" science fiction such as Isaac Asimov's Foundation series, built on mathematical sociology, science fiction critic Gary Westfahl argues that while neither term is part of a rigorous taxonomy, they are approximate ways of characterizing stories that reviewers and commentators have found useful.
I, Robot is a fixup collection made up of science fiction short stories by American writer Isaac Asimov. The stories originally appeared in the American magazines Super Science Stories and Astounding Science Fiction between 1940 and 1950 and were then compiled into a single publication by Gnome Press in 1950, in an initial edition of 5,000 copies.
The Three Laws of Robotics are a set of rules devised by science fiction author Isaac Asimov, which were to be followed by robots in several of his stories. The rules were introduced in his 1942 short story "Runaround", although similar restrictions had been implied in earlier stories.
Reginald Bretnor was an American science fiction author who flourished between the 1950s and 1980s. Most of his fiction was in short story form, and usually featured a whimsical story line or ironic plot twist. He also wrote on military theory and public affairs, and edited some of the earliest books to consider SF from a literary theory and criticism perspective.
Science fiction 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, mutants, 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 Gods Themselves is a 1972 science fiction novel written by Isaac Asimov, and his first original work in the science fiction genre in fifteen years. It won the Nebula Award for Best Novel in 1972, and the Hugo Award for Best Novel in 1973.
Military science fiction is a subgenre of science fiction and military fiction that depicts the use of science fiction technology, including spaceships and weapons, for military purposes and usually principal characters who are members of a military organization, usually during a war; occurring sometimes in outer space or on a different planet or planets. It exists in a range of media, including literature, comics, film, television and video games.
George Edgar Slusser was an American scholar, professor and writer. Slusser was a well-known science fiction critic. A professor emeritus of comparative literature at University of California, Riverside, he was the first curator of the Eaton collection.
Timescape is a 1980 science fiction novel by American writer Gregory Benford. It won the 1981 Nebula and 1980 British Science Fiction Award, and the 1981 John W. Campbell Memorial Award for Best Science Fiction Novel. It won the 1981 Ditmar Award for Best International Fiction. The novel was widely hailed by both critics of science fiction and mainstream literature for its fusion of detailed character development and interpersonal drama with more standard science fiction fare such as time travel and ecological issues.
In science fiction, hyperspace is a concept relating to higher dimensions as well as parallel universes and a faster-than-light (FTL) method of interstellar travel. In its original meaning, the term hyperspace was simply a synonym for higher-dimensional space. This usage was most common in 19th-century textbooks and is still occasionally found in academic and popular science texts, for example, Hyperspace (1994). Its science fiction usage originated in the magazine Amazing Stories Quarterly in 1931 and within several decades it became one of the most popular tropes of science fiction, popularized by its use in the works of authors such as Isaac Asimov and E. C. Tubb, and media franchises such as Star Wars.
In science fiction, a time viewer, temporal viewer, or chronoscope is a device that allows another point in time to be observed. The concept has appeared since the late 19th century, constituting a significant yet relatively obscure subgenre of time travel fiction and appearing in various media including literature, cinema, and television. Stories usually explain the technology by referencing cutting-edge science, though sometimes invoking the supernatural instead. Most commonly only the past can be observed, though occasionally time viewers capable of showing the future appear; these devices are sometimes limited in terms of what information about the future can be obtained. Other variations on the concept include being able to listen to the past but not view it.
A fix-up is a novel created from several short fiction stories that may or may not have been initially related or previously published. The stories may be edited for consistency, and sometimes new connecting material, such as a frame story or other interstitial narration, is written for the new work. The term was coined by the science fiction writer A. E. van Vogt, who published several fix-ups of his own, including The Voyage of the Space Beagle, but the practice exists outside of science fiction. The use of the term in science fiction criticism was popularised by the first (1979) edition of The Encyclopedia of Science Fiction, edited by Peter Nicholls, which credited van Vogt with the term’s creation. The name “fix-up” comes from the changes that the author needs to make in the original texts, to make them fit together as though they were a novel. Foreshadowing of events from the later stories may be jammed into an early chapter of the fix-up, and character development may be interleaved throughout the book. Contradictions and inconsistencies between episodes are usually worked out.
The hypothetical particles tachyons, defined through being faster than light, have inspired many occurrences in fiction. In general, tachyons are a standby mechanism upon which many science fiction authors rely to establish faster-than-light communication, with or without reference to causality issues, as well as a means to achieve faster-than-light travel. Science writer Sidney Perkowitz commented "that the very word "tachyon," because of its unusual Greek-origin spelling and engagingly catchy hard "ch" sound, lends a certain "science-ness" or "science coolness to fiction." Starting in the 1970s, tachyons were used in science-fiction to present a seemingly-plausible explanation for time travel and communication through time. Peter Nicholls, in The Encyclopedia of Science Fiction, describes Gregory Benford's Timescape (1980) as the first work to use tachyons to this effect "with some care", where scientists send a message to the past trying to change history. Glen Cook's 1985 novel A Matter of Time features a much less stringently described "tachyon generator" to "transmit [both to the past and] to the far future". Uses of the concept for space travel appeared in association with "the Asgard, the benevolent alien race in the Stargate SG-1 television series (1997–2007)", and in the 2001 film K-Pax, which coined the term "tachyonic speeds" for "multiples of light speed". An "unabashed" use appeared already in 1969, where "Bob Shaw's The Palace of Eternity features such delights as a million-ton tachyonic spaceship travelling at 30,000 times the speed of light." In the Star Trek franchise, in addition to facilitating faster-than-light travel, tachyons have been mentioned "for varied purposes, including cloaking a spacecraft, detection" of such cloaking and overcoming defensive shields, which has been regarded as "technobabble" by Mashable contributor Keith Wagstaff: dialogue that implies a scientific explanation, using a term with a real scientific concept behind it, "but really doesn't mean much."
Black holes, objects whose gravity is so strong that nothing—including light—can escape them, have been depicted in fiction since at least the pulp era of science fiction, before the term black hole was coined. A common portrayal at the time was of black holes as hazards to spacefarers, a motif that has also recurred in later works. The concept of black holes became popular in science and fiction alike in the 1960s. Authors quickly seized upon the relativistic effect of gravitational time dilation, whereby time passes more slowly closer to a black hole due to its immense gravitational field. Black holes also became a popular means of space travel in science fiction, especially when the notion of wormholes emerged as a relatively plausible way to achieve faster-than-light travel. In this concept, a black hole is connected to its theoretical opposite, a so-called white hole, and as such acts as a gateway to another point in space which might be very distant from the point of entry. More exotically, the point of emergence is occasionally portrayed as another point in time—thus enabling time travel—or even an entirely different universe.
The Travel Tales of Mr. Joseph Jorkens is a collection of fantasy short stories by writer Lord Dunsany. It was first published in London by G. P. Putnam's Sons in April, 1931, with the American edition following in September of the same year from the same publisher. It was the first collection of Dunsany's Jorkens tales to be published.
