Geon (physics)
In theoretical general relativity, a geon is a nonsingular electromagnetic or gravitational wave which is held together in a confined region by the gravitational attraction of its own field energy. They were first investigated theoretically in 1955 by J. A. Wheeler, who coined the term as a contraction of "gravitational electromagnetic entity". Overview Since general relativity is a classical field theory, Wheeler's concept of a geon does not treat them as quantum-mechanical entities, and this generally remains true today. Nonetheless, Wheeler speculated that there might be a relationship between geons and elementary particles. This idea continues to attract some attention among physicists, but in the absence of a viable theory of quantum gravity, the accuracy of this speculative idea cannot be tested. Wheeler did not present explicit geon solutions to the vacuum Einstein field equation, a gap which was partially filled by Brill and Hartle in 1964 by the Brill–Hartle geon. ...

Geon (psychology)
Geons are the simple 2D or 3D forms such as cylinder (geometry), cylinders, bricks, Wedge (geometry), wedges, Cone (geometry), cones, circles and rectangles corresponding to the simple parts of an object in Irving Biederman, Biederman's recognition-by-components theory. The theory proposes that the visual input is matched against structural representations of objects in the brain. These structural representations consist of geons and their relations (e.g., an ice cream cone could be broken down into a sphere located above a cone (geometry), cone). Only a modest number of geons (< 40) are assumed. When combined in different relations to each other (e.g., on-top-of, larger-than, end-to-end, end-to-middle) and coarse metric variation such as aspect ratio and 2D orientation, billions of possible 2- and 3-geon objects can be generated. Two classes of shape-based visual identification that are not done through geon representations, are those involved in: a) distinguishing between similar fa ...

Geon (geology)
The term geon (for geological eon) refers to large, geologic units of time. Geologists traditionally subdivide Earth history into a hierarchy of named intervals: eons, eras, periods, etc. (e.g., the Jurassic Period of the Mesozoic Era). Historians subdivide the history of human activity into intervals that are comparatively much shorter. In both geological and historical scales, the divisions of equal rank are characteristically of unequal duration, and the identification of a particular interval is primarily based on its fossil, artifact, or cultural content (e.g., Carboniferous, Neolithic, Dark Ages, Ming Dynasty). Both scales are calibrated against numerical ages obtained separately. An alternative way of referring to the past is to use a scale with intervals of equal duration. We speak of a given decade, century, or millennium. For the enormously long geologic time frame, it is advantageous to use corresponding large, equal time intervals encompassing the events and process ...

Geon (Korean Name)
Gun, also spelled Geon, Kŏn, Keon, Gon, Kuhn, or Kun, is a single-syllable masculine Korean given name, as well as an element in some two-syllable given names. The meaning differs based on the hanja used to write it. Hanja There are 15 hanja with this reading, and variant forms of two of those, on the South Korean government's official list of hanja which may be used in given names; they are: # (): "to construct" #* (variant) # (): "sky" #*(): "dry" #* (variant) # (): "object", "matter" # (): "strong" # (): "towel" # (): "respect" # (): "door latch" # (): "key" # (): "error" # (): "sinew" # (): "cripple" # (): "wane" # (): "to pick" # (): name of a body of waterSpecifically, the old name of the South Xinbu River () in Jingmen City, Hubei.

Geonim
''Geonim'' ( he, גאונים; ; also transliterated Gaonim, singular Gaon) were the presidents of the two great Babylonian Talmudic Academies of Sura and Pumbedita, in the Abbasid Caliphate, and were the generally accepted spiritual leaders of the Jewish community worldwide in the early medieval era, in contrast to the ''Resh Galuta'' (exilarch) who wielded secular authority over the Jews in Islamic lands. ''Geonim'' is the plural of (''Gaon) , which means "pride" or "splendor" in Biblical Hebrew and since the 19th century "genius" as in modern Hebrew. As a title of a Babylonian college president it meant something like "His Excellency". The ''Geonim'' played a prominent and decisive role in the transmission and teaching of Torah and Jewish law. They taught Talmud and decided on issues on which no ruling had been rendered during the period of the Talmud. The Geonim were also spiritual leaders of the Jewish community of their time. Era The period of the Geonim began in 58 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
King Of The Monsters (video Game)
is a fighting game developed by SNK, released for arcades in Japan in 1991, and ported to the Neo Geo AES later that same year. The game features playable giant monsters that are reminiscent of characters from '' kaiju'' and ''tokusatsu'' films. In 1992, a sequel titled '' King of the Monsters 2'' was released for arcades. Months later, ''King of the Monsters'' was ported to the Super Nintendo Entertainment System. It would then be ported to the Sega Genesis in 1993. It was included in the video game '' SNK Arcade Classics Vol. 1'', which was released for the Wii, PlayStation 2 and PSP in 2008. Gameplay Players choose one of six monsters (four in the 16-bit ports) for battle, and two players can join forces to fight the monsters together. Battles end when one of the monsters is pinned for a three count or if time expires (in which case the player loses). The game consists of 12 total levels (8 in the 16-bit ports) which takes place in 6 cities in a futuristic 1996 Ja ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emotions
Emotions are mental states brought on by neurophysiological changes, variously associated with thoughts, feelings, behavioral responses, and a degree of pleasure or displeasure. There is currently no scientific consensus on a definition. Emotions are often intertwined with mood, temperament, personality, disposition, or creativity. Research on emotion has increased over the past two decades with many fields contributing including psychology, medicine, history, sociology of emotions, and computer science. The numerous theories that attempt to explain the origin, function and other aspects of emotions have fostered more intense research on this topic. Current areas of research in the concept of emotion include the development of materials that stimulate and elicit emotion. In addition, PET scans and fMRI scans help study the affective picture processes in the brain. From a mechanistic perspective, emotions can be defined as "a positive or negative experience that is assoc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
