The Entity (Anderson)
"Entity" is a science fiction short story by American writers Poul Anderson and John Gergen, which appeared in the June 1949 issue of '' Astounding Science Fiction''. "Entity" was the fifth story published by Anderson, and the only story published by Gergen, a friend of him from the Minneapolis Fantasy Society. Plot summary The interstellar scout ship ''Diogenes'' has discovered an ancient, deserted alien outpost on an airless planet. The most puzzling object at the outpost is a featureless black sphere resting on a concrete pedestal that instantly drains all power from any device that is exposed to it. The sphere is impervious to all attempts to study it, and when the crew of the ''Diogenes'' attempt to lift it off its pedestal with a levitation machine, it shorts out their ship's main generators. Repairing the generators will require weeks, and morale is already low when the ship's biologist hypothesizes that the sphere is actually a sentient entity which is actively resisti ...

Poul Anderson
Poul William Anderson (November 25, 1926 – July 31, 2001) was an American fantasy and science fiction author who was active from the 1940s until the 21st century. Anderson wrote also historical novels. His awards include seven Hugo Awards and three Nebula Awards. Biography Poul Anderson was born on November 25, 1926, in Bristol, Pennsylvania to Scandinavian parents. Soon after his birth, his father, Anton Anderson relocated the family to Texas, where they lived for more than ten years. After Anton Anderson's death, his widow took the children to Denmark. The family returned to the United States after the beginning of World War II, settling eventually on a Minnesota farm. While he was an undergraduate student at the University of Minnesota, Anderson's first stories were published by editor John W. Campbell in the magazine ''Astounding Science Fiction'': "Tomorrow's Children" by Anderson and F. N. Waldrop in March 1947 and a sequel, "Chain of Logic" by Anderson alone, in July ...

Potential Energy
In physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors. Common types of potential energy include the gravitational potential energy of an object, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field. The unit for energy in the International System of Units (SI) is the joule, which has the symbol J. The term ''potential energy'' was introduced by the 19th-century Scottish engineer and physicist William Rankine, although it has links to Greek philosopher Aristotle's concept of potentiality. Potential energy is associated with forces that act on a body in a way that the total work done by these forces on the body depends only on the initial and final positions of the body in space. These forces, that are called ''conservative forces'', can be represented at every point in space by vec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Sentinel (short Story)
"The Sentinel" is a science fiction short story by British author Arthur C. Clarke, written in 1948 and first published in 1951 as "Sentinel of Eternity", which was used as a starting point for the 1968 novel and film ''2001: A Space Odyssey''. Publication history "The Sentinel" was written in 1948 for a BBC competition (in which it failed to place) and was first published in the magazine '' 10 Story Fantasy'' in its Spring 1951 issue, under the title "Sentinel of Eternity". It was subsequently published as part of the short story collections '' Expedition to Earth'' (1953), ''The Nine Billion Names of God'' (1967), and ''The Lost Worlds of 2001'' (1972). Despite the story's initial failure, it changed the course of Clarke's career. Anthology '' The Sentinel'' (published 1982) is also the title of a collection of Arthur C. Clarke short stories, which includes the eponymous "The Sentinel", "Guardian Angel" (the inspiration for his 1953 novel ''Childhood's End''), "The S ...

Sphere (1998 Film)
''Sphere'' is a 1998 American science fiction psychological thriller film directed and produced by Barry Levinson, adapted by Kurt Wimmer, and starring Dustin Hoffman, Sharon Stone, and Samuel L. Jackson. ''Sphere'' is based on the 1987 novel of the same name by Michael Crichton. The film was released in the United States on February 13, 1998. Plot A spacecraft, presumed to be of alien origin, is discovered on the floor of the Pacific Ocean, estimated to have been there for nearly 300 years. A team of experts, including marine biologist Dr. Beth Halperin, mathematician Dr. Harry Adams, astrophysicist Dr. Ted Fielding, psychologist Dr. Norman Goodman, and U.S. Navy Captain Harold Barnes, are assembled and taken to the Habitat, a state-of-the-art underwater living environment located near the spacecraft. Upon examination of the spacecraft, they are perplexed to learn it is not alien at all, but rather American in origin. However, its technology far surpasses any in the present ...

Startling Stories
''Startling Stories'' was an American pulp science fiction magazine, published from 1939 to 1955 by publisher Ned Pines' Standard Magazines. It was initially edited by Mort Weisinger, who was also the editor of ''Thrilling Wonder Stories'', Standard's other science fiction title. ''Startling'' ran a lead novel in every issue; the first was '' The Black Flame'' by Stanley G. Weinbaum. When Standard Magazines acquired ''Thrilling Wonder'' in 1936, it also gained the rights to stories published in that magazine's predecessor, ''Wonder Stories'', and selections from this early material were reprinted in ''Startling'' as "Hall of Fame" stories. Under Weisinger the magazine focused on younger readers and, when Weisinger was replaced by Oscar J. Friend in 1941, the magazine became even more juvenile in focus, with clichéd cover art and letters answered by a "Sergeant Saturn". Friend was replaced by Sam Merwin Jr. in 1945, and Merwin was able to improve the quality of the fictio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychotechnic League
The Psychotechnic League is a future history created by American science fiction writer Poul Anderson. The name "Psychotechnic League" was invented by Sandra Miesel during the early 1980s, to capitalize on Anderson's better-known Polesotechnic League future history. Anderson published 21 novels, novellas and short stories set in this future between 1949 and 1957, with a 22nd published in 1968. Anderson did not write the stories in chronological order. He included a series timeline in the Winter 1955 issue of'' Startling Stories ''to accompany the novella "The Snows of Ganymede". By the late 1950s, Anderson's political beliefs had altered to the extent that he was uncomfortable with the political philosophy implied by the series, and he abandoned it. In particular, he had reversed his earlier strong endorsement for the United Nations as the basis of a world government, an opinion which was the main plot element of several earlier stories in the series.

Hertz
The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), equivalent to one event (or cycle) per second. The hertz is an SI derived unit whose expression in terms of SI base units is s−1, meaning that one hertz is the reciprocal of one second. It is named after Heinrich Rudolf Hertz (1857–1894), the first person to provide conclusive proof of the existence of electromagnetic waves. Hertz are commonly expressed in multiples: kilohertz (kHz), megahertz (MHz), gigahertz (GHz), terahertz (THz). Some of the unit's most common uses are in the description of periodic waveforms and musical tones, particularly those used in radio- and audio-related applications. It is also used to describe the clock speeds at which computers and other electronics are driven. The units are sometimes also used as a representation of the energy of a photon, via the Planck relation ''E'' = ''hν'', where ''E'' is the photon's energy, ''ν'' is its freq ...

Electromagnetic Radiation
In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic field, electromagnetic (EM) field, which propagate through space and carry momentum and electromagnetic radiant energy. It includes radio waves, microwaves, infrared, Light, (visible) light, ultraviolet, X-rays, and gamma rays. All of these waves form part of the electromagnetic spectrum. Classical electromagnetism, Classically, electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric field, electric and magnetic fields. Depending on the frequency of oscillation, different wavelengths of electromagnetic spectrum are produced. In a vacuum, electromagnetic waves travel at the speed of light, commonly denoted ''c''. In homogeneous, isotropic media, the oscillations of the two fields are perpendicular to each other and perpendicular to the direction of energy and wave propagation, forming a transverse wave. The position of an electromagnetic wave w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biologist
A biologist is a scientist who conducts research in biology. Biologists are interested in studying life on Earth, whether it is an individual cell, a multicellular organism, or a community of interacting populations. They usually specialize in a particular branch (e.g., molecular biology, zoology, and evolutionary biology) of biology and have a specific research focus (e.g., studying malaria or cancer). Biologists who are involved in basic research have the aim of advancing knowledge about the natural world. They conduct their research using the scientific method, which is an empirical method for testing hypotheses. Their discoveries may have applications for some specific purpose such as in biotechnology, which has the goal of developing medically useful products for humans. In modern times, most biologists have one or more academic degrees such as a bachelor's degree plus an advanced degree like a master's degree or a doctorate. Like other scientists, biologists can be fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
English Language
English is a West Germanic language of the Indo-European language family, with its earliest forms spoken by the inhabitants of early medieval England. It is named after the Angles, one of the ancient Germanic peoples that migrated to the island of Great Britain. Existing on a dialect continuum with Scots, and then closest related to the Low Saxon and Frisian languages, English is genealogically West Germanic. However, its vocabulary is also distinctively influenced by dialects of France (about 29% of Modern English words) and Latin (also about 29%), plus some grammar and a small amount of core vocabulary influenced by Old Norse (a North Germanic language). Speakers of English are called Anglophones. The earliest forms of English, collectively known as Old English, evolved from a group of West Germanic (Ingvaeonic) dialects brought to Great Britain by Anglo-Saxon settlers in the 5th century and further mutated by Norse-speaking Viking settlers starting in the 8th and 9th ...

Extraterrestrial Life
Extraterrestrial life, colloquially referred to as alien life, is life that may occur outside Earth and which did not originate on Earth. No extraterrestrial life has yet been conclusively detected, although efforts are underway. Such life might range from simple forms like prokaryotes to intelligent beings, possibly bringing forth civilizations that might be far more advanced than humankind. The Drake equation speculates about the existence of sapient life elsewhere in the universe. The science of extraterrestrial life is known as astrobiology. Speculation about the possibility of inhabited "worlds" outside the planet Earth dates back to antiquity. Multiple early Christian writers discussed the idea of a "plurality of worlds" as proposed by earlier thinkers such as Democritus; Augustine references Epicurus's idea of innumerable worlds "throughout the boundless immensity of space" (originally expressed in his Letter to Herodotus) in ''The City of God''.
