The Algebraist
''The Algebraist'' is a science fiction novel by Scottish writer Iain M. Banks, published in print in 2004. It was nominated for a Hugo Award for Best Novel in 2005. It was his third science fiction novel not to be based or set in The Culture, the earlier two being '' Against a Dark Background'' and '' Feersum Endjinn''. Plot summary The novel takes place in 4034. With the assistance of other species, humans have spread across the galaxy, which is largely ruled by the Mercatoria, a complex feudal hierarchy, with a religious zeal to rid the galaxy of artificial intelligences, which were blamed for a previous war. The central character is the human Fassin Taak who is a "Slow Seer" at the Court of the Nasqueron Dwellers. The Nasqueron's star system has been cut off from the rest of Mercatoria civilization because their portal (the only means of faster than light travel) was destroyed by the Beyonders. The Beyonders are a large fleet of space marauders who originated fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Faster Than Light Travel
Faster-than-light (also FTL, superluminal or supercausal) travel and communication are the conjectural propagation of matter or information faster than the speed of light (). The special theory of relativity implies that only particles with zero rest mass (i.e., photons) may travel ''at'' the speed of light, and that nothing may travel faster. Particles whose speed exceeds that of light (tachyons) have been hypothesized, but their existence would violate causality and would imply time travel. The scientific consensus is that they do not exist. "Apparent" or "effective" FTL, on the other hand, depends on the hypothesis that unusually distorted regions of spacetime might permit matter to reach distant locations in less time than light could in normal ("undistorted") spacetime. As of the 21st century, according to current scientific theories, matter is required to travel at slower-than-light (also STL or subluminal) speed with respect to the locally distorted spacetime region.

Simulated Reality
The simulation theory is the hypothesis that reality could be simulated—for example by quantum computer simulation—to a degree indistinguishable from "true" reality. It could contain conscious minds that may or may not know that they live inside a simulation. This is quite different from the current, technologically achievable concept of virtual reality, which is easily distinguished from the experience of actuality. Simulated reality, by contrast, would be hard or impossible to separate from "true" reality. There has been much debate over this topic, ranging from philosophical discourse to practical applications in computing. Arguments Simulation argument A version of the simulation hypothesis was first theorized as a part of a philosophical argument on the part of René Descartes, and later by Hans Moravec. The philosopher Nick Bostrom developed an expanded argument examining the probability of our reality being a simulation. His argument states that at least one of t ...

Night Shade Books
Night Shade Books is an American, San Francisco–based imprint, formerly an independent publishing company, that specializes in science fiction, fantasy, and horror. Among its publications have been the U.S. edition of Iain M. Banks' novel ''The Algebraist'', which was nominated for a Hugo Award, and Paolo Bacigalupi's novel ''The Windup Girl'', which won several awards. The company was started in 1997 by Jason Williams, with Jeremy Lassen coming on board as a partner shortly after the company's founding. Night Shade won the 2003 World Fantasy Award (Non-Professional). On July 9, 2010, the Science Fiction and Fantasy Writers of America (SFWA) placed Night Shade Books on probation after it admitted to, and apologized to authors for, contractual irregularities. On November 30, 2011, SFWA lifted the probation based on good behavior during the probationary period. However, an investigation was reopened when further complaints were submitted to SFWA the following year. Once Night ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warlord
A warlord is a person who exercises military, economic, and political control over a region in a country without a strong national government; largely because of coercive control over the armed forces. Warlords have existed throughout much of history, albeit in a variety of different capacities within the political, economic, and social structure of states or ungoverned territories. The term is most often applied to China in the mid-19th century and the early 20th century. The term can also be used for any supreme military leader. Historical origins and etymology The first appearance of the word "warlord" dates to 1856, when used by American philosopher and poet Ralph Waldo Emerson in a highly critical essay on the aristocracy in England, "Piracy and war gave place to trade, politics and letters; the war-lord to the law-lord; the privilege was kept, whilst the means of obtaining it were changed." During the First World War, the term appeared in China as ''Junfa'' ( 軍閥), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transformation (mathematics)
In mathematics, a transformation is a function ''f'', usually with some geometrical underpinning, that maps a set ''X'' to itself, i.e. . Examples include linear transformations of vector spaces and geometric transformations, which include projective transformations, affine transformations, and specific affine transformations, such as rotations, reflections and translations. Partial transformations While it is common to use the term transformation for any function of a set into itself (especially in terms like "transformation semigroup" and similar), there exists an alternative form of terminological convention in which the term "transformation" is reserved only for bijections. When such a narrow notion of transformation is generalized to partial functions, then a partial transformation is a function ''f'': ''A'' → ''B'', where both ''A'' and ''B'' are subsets of some set ''X''. Algebraic structures The set of all transformations on a given base set, together with function ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lagrange Point
In celestial mechanics, the Lagrange points (; also Lagrangian points or libration points) are points of equilibrium for small-mass objects under the influence of two massive orbiting bodies. Mathematically, this involves the solution of the restricted three-body problem in which two bodies are far more massive than the third. Normally, the two massive bodies exert an unbalanced gravitational force at a point, altering the orbit of whatever is at that point. At the Lagrange points, the gravitational forces of the two large bodies and the centrifugal force balance each other. This can make Lagrange points an excellent location for satellites, as few orbit corrections are needed to maintain the desired orbit. Small objects placed in orbit at Lagrange points are in equilibrium in at least two directions relative to the center of mass of the large bodies. For any combination of two orbital bodies there are five Lagrange points, L1 to L5, all in the orbital plane of the two lar ...

Gravitational Gradient
Gravity gradiometry is the study and measurement of variations ( anomalies) in the Earth's gravity field. The gravity gradient tensor is the spatial rate of change of gravitational acceleration; as acceleration is a vector quantity, with magnitude and three-dimensional direction, the full gravity gradient is a 3x3 tensor. Gravity gradiometry is used by oil and mineral prospectors to measure the density of the subsurface, effectively by measuring the rate of change of gravitational acceleration due to underlying rock properties. From this information it is possible to build a picture of subsurface anomalies which can then be used to more accurately target oil, gas and mineral deposits. It is also used to image water column density, when locating submerged objects, or determining water depth (bathymetry). Physical scientists use gravimeters to determine the exact size and shape of the earth and they contribute to the gravity compensations applied to inertial navigation systems. ...

Military Draft
Conscription (also called the draft in the United States) is the state-mandated enlistment of people in a national service, mainly a military service. Conscription dates back to antiquity and it continues in some countries to the present day under various names. The modern system of near-universal national conscription for young men dates to the French Revolution in the 1790s, where it became the basis of a very large and powerful military. Most European nations later copied the system in peacetime, so that men at a certain age would serve 1–8 years on active duty and then transfer to the reserve force. Conscription is controversial for a range of reasons, including conscientious objection to military engagements on religious or philosophical grounds; political objection, for example to service for a disliked government or unpopular war; sexism, in that historically men have been subject to the draft in the most cases; and ideological objection, for example, to a perceived vio ...
