The Ringworld Engineers
''The Ringworld Engineers'' is a 1979 science fiction novel by American writer Larry Niven. It is the first sequel to Niven's ''Ringworld'' and was nominated for both the Hugo Award, Hugo and Locus Awards in 1981. Origin In the introduction to the novel, Niven says that he never planned to write more than one ''Ringworld'' novel, but that he did so, in a large part, due to fan support. Firstly, the popularity of ''Ringworld'' resulted in a demand for a sequel. Secondly, many fans had identified numerous Ringworld#Ringworld engineering, engineering problems in the Ringworld as described in the novel. The first major problem was that the Ringworld, being a rigid structure, was not actually in orbit around the star it encircled and would eventually drift, resulting in the entire structure colliding with its sun and disintegrating. In the novel's introduction, Niven says that Massachusetts Institute of Technology, MIT students attending the 1971 World Science Fiction Convention chant ...

WikiProject Novels
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Kzin
The Kzinti (singular Kzin) are a fictional, warlike and bloodthirsty race of cat-like extraterrestrial life, aliens in Larry Niven's ''Known Space'' series. The Kzinti were initially introduced in Niven's story "The Warriors" (originally in ''Worlds of If'' (1966), collected in ''Tales of Known Space'' (1975)) and "The Soft Weapon" (1967), collected in ''Neutron Star'' (1968). A Kzin character, Speaker-to-Animals (later known as Chmeee), subsequently played a significant role in Niven's Hugo Award, Hugo and Nebula Award, Nebula award-winning ''Ringworld'' (1970) and ''Ringworld Engineers'' (1980), giving considerably more background of the Kzinti and their interactions with human civilizations. Following ''Ringworld'', Niven permitted several friends to write stories taking place in the time following "The Warriors" but before "The Soft Weapon"; these stories (including a handful by Niven) were collected in some volumes of ''The Man-Kzin Wars'', which eventually reached fourteen v ...

Ballantine Books
Ballantine Books is a major book publisher located in the United States, founded in 1952 by Ian Ballantine with his wife, Betty Ballantine. It was acquired by Random House in 1973, which in turn was acquired by Bertelsmann in 1998 and remains part of that company today. Ballantine's original logo was a pair of mirrored letter Bs back to back, while its current logo is two Bs stacked to form an elaborate gate. The firm's early editors were Stanley Kauffmann and Bernard Shir-Cliff. History Following Fawcett Publications' controversial 1950 introduction of Gold Medal paperback originals rather than reprints, Lion Books, Avon and Ace also decided to publish originals. In 1952, Ian Ballantine, a founder of Bantam Books, announced that he would "offer trade publishers a plan for simultaneous publishing of original titles in two editions, a hardcover 'regular' edition for bookstore sale, and a paper-cover, 'newsstand' size, low-priced edition for mass market sale."

Holt, Rinehart, And Winston
Holt McDougal is an American publishing company, a division of Houghton Mifflin Harcourt, that specializes in textbooks for use in high schools. The Holt name is derived from that of U.S. publisher Henry Holt (1840–1926), co-founder of the earliest ancestor business, but Holt McDougal is distinct from contemporary Henry Holt and Company, which claims the history from 1866. The companies publish different kinds of books. History Holt, Rinehart and Winston (HRW) was created in March 1960 by the merger of Henry Holt and Company of New York City (established 1866 as Leypoldt and Holt); Rinehart & Company of New York, descendant of Farrar & Rinehart (est. 1929); and the John C. Winston Company of Philadelphia (est. 1884). ''The Wall Street Journal'' reported on March 1, 1960, that Holt stockholders had approved the merger, last of the three approvals. "Henry Holt is the surviving concern, but will be known as Holt, Rinehart, Winston, Inc.""Henry Holt Merger". ''The Wall Street J ...

Galileo Magazine
Galileo di Vincenzo Bonaiuti de' Galilei (15 February 1564 – 8 January 1642) was an Italian astronomer, physicist and engineer, sometimes described as a polymath. Commonly referred to as Galileo, his name was pronounced (, ). He was born in the city of Pisa, then part of the Duchy of Florence. Galileo has been called the "father" of observational astronomy, modern physics, the scientific method, and modern science. Galileo studied speed and velocity, gravity and free fall, the principle of relativity, inertia, projectile motion and also worked in applied science and technology, describing the properties of pendulums and "hydrostatic balances". He invented the thermoscope and various military compasses, and used the telescope for scientific observations of celestial objects. His contributions to observational astronomy include telescopic confirmation of the phases of Venus, observation of the four largest satellites of Jupiter, observation of Saturn's rings, and anal ...

Protector (novel)
''Protector'' is a 1973 science fiction novel by American writer Larry Niven, set in his Known Space universe. It was nominated for the Hugo in 1974, and placed fourth in the annual Locus poll for that year. The work fleshes out a species called the Pak, originally introduced in a 1967 story called "The Adults", which forms the first half of the novel (there titled ''Phssthpok''); the second half is titled ''Vandervecken''. The Pak also appear in several of Niven's later works, including the later volumes of the ''Ringworld'' series and the novel '' Destroyer of Worlds'' which serves as a semi-sequel to ''Protector''. Plot summary The novel comprises two phases in the same space that are separated by 220 years of time. Its central conceit is that Humans evolved from the juvenile stage of the Pak, a species with a distinct adult form ("Protectors") that has immense strength and intelligence and cares only about younger Pak of their bloodline. A key plot point is that transit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teela Brown
This is a list of Character (arts), fictional characters featured in the ''Known Space'' novels by Larry Niven. Individual characters Sigmund Ausfaller Sigmund Ausfaller, a native of Earth, is a member of the Amalgamated Regional Militia ("ARM"), working in the Bureau of Alien Affairs on Earth. To protect Pierson's Puppeteers, puppeteer (and Earth) interests, in "Neutron Star" Ausfaller plants a bomb in the lifesystem of Shaeffer's ship, the ''Skydiver'', so that Shaeffer will not attempt to steal it. Years later, in ''The Borderlands of Sol'', when Shaeffer encounters him on Jinx (Known Space), Jinx, he offers Shaeffer and Carlos Wu a ride home to Earth on his ship, ''Hobo Kelly'', in hopes of attracting the attention of whoever or whatever was causing ships to disappear when entering or leaving Sol system. Some years later, Ausfaller, having almost caught up with Shaeffer on Fafnir, is killed by Ander Smittarasheed in order to protect Smittarasheed's interest in the special nano ...

Laser
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word "laser" is an acronym for "light amplification by stimulated emission of radiation". The first laser was built in 1960 by Theodore H. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow. A laser differs from other sources of light in that it emits light which is ''coherent''. Spatial coherence allows a laser to be focused to a tight spot, enabling applications such as laser cutting and lithography. Spatial coherence also allows a laser beam to stay narrow over great distances (collimation), enabling applications such as laser pointers and lidar (light detection and ranging). Lasers can also have high temporal coherence, which allows them to emit light with a very narrow spectrum. Alternatively, temporal coherence can be used to produce ultrashort pulses of ligh ...

Solar Flare
A solar flare is an intense localized eruption of electromagnetic radiation in the Sun's atmosphere. Flares occur in active regions and are often, but not always, accompanied by coronal mass ejections, solar particle events, and other solar phenomena. The occurrence of solar flares varies with the 11-year solar cycle. Solar flares are thought to occur when stored magnetic energy in the Sun's atmosphere accelerates charged particles in the surrounding plasma. This results in the emission of electromagnetic radiation across the electromagnetic spectrum. High-energy electromagnetic radiation from solar flares is absorbed by the daylight side of Earth's upper atmosphere, in particular the ionosphere, and does not reach the surface. This absorption can temporarily increase the ionization of the ionosphere which may interfere with short-wave radio communication. The prediction of solar flares is an active area of research. Flares also occur on other stars, where the term ''stellar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scrith
''Ringworld'' is a 1970 science fiction novel by Larry Niven, set in his Known Space universe and considered a classic of science fiction literature. ''Ringworld'' tells the story of Louis Wu and his companions on a mission to the Ringworld, a rotating wheel artificial world, an alien construct in space in diameter. Niven later added three sequel novels and then cowrote, with Edward M. Lerner, four prequels and a final sequel; the five latter novels constitute the Fleet of Worlds series. All the novels in the Ringworld series tie into numerous other books set in Known Space. ''Ringworld'' won the Nebula Award in 1970, as well as both the Hugo Award and Locus Award in 1971. Plot summary On planet Earth in 2850 AD, Louis Gridley Wu is celebrating his 200th birthday. Despite his age, Louis is in perfect physical condition due to the longevity drug boosterspice.

Pak Protector
Pak Breeders and Pak Protectors are two developmental stages of fictional life in Larry Niven's Known Space universe. The Pak first appeared in "The Adults", which appeared in ''Galaxy'' in 1967; this story was expanded into the novel ''Protector'' by Larry Niven (1973). The Pak also appear in several of Niven's later novels, notably those set in the Ringworld. '' Destroyer of Worlds'' depicts a confrontation between the Pak and the Puppeteers. Narrative purpose Niven has written that he invented the Protectors as a thought experiment to explain the common effects of aging on humans and to create a fictional evolutionary explanation for humans' long lives after females have passed reproductive age. Accordingly, most of the positive attributes of Protectors are based on negative human aging effects: swollen joints, decreased muscle-fat ratio, weakening heart, invariant diet, decreasing height, facial atrophy, leathery skin, hair loss, lack of sex drive, and tooth loss are all t ...

Mars
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, only being larger than Mercury (planet), Mercury. In the English language, Mars is named for the Mars (mythology), Roman god of war. Mars is a terrestrial planet with a thin atmosphere (less than 1% that of Earth's), and has a crust primarily composed of elements similar to Earth's crust, as well as a core made of iron and nickel. Mars has surface features such as impact craters, valleys, dunes and polar ice caps. It has two small and irregularly shaped moons, Phobos (moon), Phobos and Deimos (moon), Deimos. Some of the most notable surface features on Mars include Olympus Mons, the largest volcano and List of tallest mountains in the Solar System, highest known mountain in the Solar System and Valles Marineris, one of the largest canyons in the Solar System. The North Polar Basin (Mars), Borealis basin in the Northern Hemisphere covers approximately 40% of the planet and may be a la ...
