Timescape
''Timescape'' is a 1980 science fiction novel by American writer Gregory Benford (with unbilled co-author Hilary Foister, Benford's sister-in-law, who is credited as having "contributed significantly to the manuscript"). 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. Pocket Books used the title of this book for their science fiction imprint. Plot summary The story is written from two viewpoints, equidistant from the novel's publication in 1980. The first thread is set in a 1998 ravaged by ecological disasters such as algal blooms and diebacks on the brink of large scale extinctions. ...

Campbell Award (best Novel)
The John W. Campbell Memorial Award for Best Science Fiction Novel, or Campbell Memorial Award, is an annual award presented by the Center for the Study of Science Fiction at the University of Kansas to the author of the best science fiction novel published in English in the preceding calendar year. It is the novel counterpart of the Theodore Sturgeon Award for best short story, awarded at the same conference by the Theodore Sturgeon Literary Trust. The award is named in honor of John W. Campbell (1910–71), whose science fiction writing and role as editor of '' Analog Science Fiction and Fact'' made him one of the most influential editors in the early history of science fiction. The award was established in 1973 by writers and critics Harry Harrison and Brian Aldiss "as a way of continuing his efforts to encourage writers to produce their best possible work." ''Locus'' magazine has listed it as one of the "major awards" of written science fiction. The winning novel is sele ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pocket Books
Pocket Books is a division of Simon & Schuster that primarily publishes paperback books. History Pocket Books produced the first mass-market, pocket-sized paperback books in the United States in early 1939 and revolutionized the publishing industry. The German Albatross Books had pioneered the idea of a line of color-coded paperback editions in 1931 under Kurt Enoch, and Penguin Books in Britain had refined the idea in 1935 and had one million books in print by the following year. Pocket Books was founded by Richard L. Simon, M. Lincoln ("Max") Schuster and Leon Shimkin, partners of Simon & Schuster, along with Robert de Graff. In 1944, the founding owners sold the company to Marshall Field III, owner of the ''Chicago Sun'' newspaper. Following Field's death, in 1957, Leon Shimkin, a Simon & Schuster partner, and James M. Jacobson bought Pocket Books for $5 million. Simon & Schuster acquired Pocket in 1966. Penguin's success inspired entrepreneur Robert de Graff, who ...

BSFA Award
The BSFA Awards are literary awards presented annually since 1970 by the British Science Fiction Association (BSFA) to honour works in the genre of science fiction. Nominees and winners are chosen based on a vote of BSFA members. More recently, members of the Eastercon convention have also been eligible to vote. BSFA Award categories The award originally included only a category for novels. Categories for short works and artists were added in 1980. The category for younger readers was added in 2021. The artists category became artwork in 1986 and a category for related non-fiction was added in 2002. A media category was awarded from 1979 to 1992.

Grandfather Paradox
A temporal paradox, time paradox, or time travel paradox is a paradox, an apparent contradiction, or logical contradiction associated with the idea of time and time travel. The notion of time travel to the future complies with current understanding of physics via relativistic time dilation, temporal paradoxes arise from circumstances involving hypothetical time travel to the past and are often used to demonstrate its impossibility. In physics, temporal paradoxes fall into two broad groups: consistency paradoxes exemplified by the grandfather paradox; and causal loops. Other paradoxes associated with time travel are a variation of the Fermi paradox and paradoxes of free will that stem from causal loops such as Newcomb's paradox. Causal loop A causal loop is a paradox of time travel that occurs when a future event is the cause of a past event, which in turn is the cause of the future event. Both events then exist in spacetime, but their origin cannot be determined. A causal loop m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Indium Antimonide
Indium antimonide (InSb) is a crystalline compound made from the elements indium (In) and antimony (Sb). It is a narrow- gap semiconductor material from the III- V group used in infrared detectors, including thermal imaging cameras, FLIR systems, infrared homing missile guidance systems, and in infrared astronomy. The indium antimonide detectors are sensitive between 1–5 μm wavelengths. Indium antimonide was a very common detector in the old, single-detector mechanically scanned thermal imaging systems. Another application is as a terahertz radiation source as it is a strong photo-Dember emitter. History The intermetallic compound was first reported by Liu and Peretti in 1951, who gave its homogeneity range, structure type, and lattice constant. Polycrystalline ingots of InSb were prepared by Heinrich Welker in 1952, although they were not very pure by today's semiconductor standards. Welker was interested in systematically studying the semiconducting properties of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morse Code
Morse code is a method used in telecommunication to encode text characters as standardized sequences of two different signal durations, called ''dots'' and ''dashes'', or ''dits'' and ''dahs''. Morse code is named after Samuel Morse, one of the inventors of the telegraph. International Morse code encodes the 26 basic Latin letters through , one accented Latin letter (), the Arabic numerals, and a small set of punctuation and procedural signals ( prosigns). There is no distinction between upper and lower case letters. Each Morse code symbol is formed by a sequence of ''dits'' and ''dahs''. The ''dit'' duration is the basic unit of time measurement in Morse code transmission. The duration of a ''dah'' is three times the duration of a ''dit''. Each ''dit'' or ''dah'' within an encoded character is followed by a period of signal absence, called a ''space'', equal to the ''dit'' duration. The letters of a word are separated by a space of duration equal to three ''dits' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Project Ozma
Project Ozma was a search for extraterrestrial intelligence (SETI) experiment started in 1960 by Cornell University astronomer Frank Drake, at the National Radio Astronomy Observatory, Green Bank at Green Bank, West Virginia. The object of the experiment was to search for signs of life in distant planetary systems through interstellar radio waves. The program was named after Princess Ozma, ruler of the fictional land of Oz, inspired by L. Frank Baum's supposed communication with Oz by radio to learn of the events in the books taking place after ''The Emerald City of Oz''. The search was publicized in articles in the popular media of the time, such as ''Time'' magazine and was described as the first modern SETI experiment. Drake used a radio telescope with a diameter of to examine the stars Tau Ceti and Epsilon Eridani near the 1,420 MHz marker frequency, the equivalent of wavelength of 21 centimeters which corresponds to the energy of a photon emitted from a hydrogen atom d ...

Frank Drake
Frank Donald Drake (May 28, 1930 – September 2, 2022) was an American astrophysicist and astrobiologist. He began his career as a radio astronomer, studying the planets of the Solar System and later pulsars. Drake expanded his interests to the search for extraterrestrial intelligence (SETI), beginning with Project Ozma in 1960, an attempt at extraterrestrial communications. He developed the Drake equation, which attempts to quantify the number of intelligent lifeforms that could potentially be discovered. Working with Carl Sagan, Drake helped to design the Pioneer plaque, the first physical message flown beyond the Solar System, and was part of the team that developed the Voyager record. Drake designed and implemented the Arecibo message in 1974, an extraterrestrial radio transmission of astronomical and biological information about Earth. Drake worked at the National Radio Astronomy Observatory, Jet Propulsion Laboratory, Cornell University, University of California at ...

Earth
Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More solar e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
