∗
The asterisk ( ), from Late Latin , from Ancient Greek , ''asteriskos'', "little star", is a typographical symbol. It is so called because it resembles a conventional image of a heraldic star. Computer scientists and mathematicians often vocalize it as star (as, for example, in ''the A* search algorithm'' or ''C*-algebra''). In English, an asterisk is usually five- or six-pointed in sans-serif typefaces, six-pointed in serif typefaces, and six- or eight-pointed when handwritten. Its most common use is to call out a footnote. It is also often used to censor offensive words. In computer science, the asterisk is commonly used as a wildcard character, or to denote pointers, repetition, or multiplication. History The asterisk has already been used as a symbol in ice age cave paintings. There is also a two thousand-year-old character used by Aristarchus of Samothrace called the , , which he used when proofreading Homeric poetry to mark lines that were duplicated. Origen is know ...

A* Search Algorithm
A* (pronounced "A-star") is a graph traversal and path search algorithm, which is used in many fields of computer science due to its completeness, optimality, and optimal efficiency. One major practical drawback is its O(b^d) space complexity, as it stores all generated nodes in memory. Thus, in practical travel-routing systems, it is generally outperformed by algorithms which can pre-process the graph to attain better performance, as well as memory-bounded approaches; however, A* is still the best solution in many cases. Peter Hart, Nils Nilsson and Bertram Raphael of Stanford Research Institute (now SRI International) first published the algorithm in 1968. It can be seen as an extension of Dijkstra's algorithm. A* achieves better performance by using heuristics to guide its search. Compared to Dijkstra's algorithm, the A* algorithm only finds the shortest path from a specified source to a specified goal, and not the shortest-path tree from a specified source to all possi ...

C*-algebra
In mathematics, specifically in functional analysis, a C∗-algebra (pronounced "C-star") is a Banach algebra together with an involution satisfying the properties of the adjoint. A particular case is that of a complex algebra ''A'' of continuous linear operators on a complex Hilbert space with two additional properties: * ''A'' is a topologically closed set in the norm topology of operators. * ''A'' is closed under the operation of taking adjoints of operators. Another important class of non-Hilbert C*-algebras includes the algebra C_0(X) of complex-valued continuous functions on ''X'' that vanish at infinity, where ''X'' is a locally compact Hausdorff space. C*-algebras were first considered primarily for their use in quantum mechanics to model algebras of physical observables. This line of research began with Werner Heisenberg's matrix mechanics and in a more mathematically developed form with Pascual Jordan around 1933. Subsequently, John von Neumann attempted to establi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Latin
Late Latin ( la, Latinitas serior) is the scholarly name for the form of Literary Latin of late antiquity.Roberts (1996), p. 537. English dictionary definitions of Late Latin date this period from the , and continuing into the 7th century in the Iberian Peninsula. This somewhat ambiguously defined version of Latin was used between the eras of Classical Latin and Medieval Latin. Scholars do not agree exactly when Classical Latin should end or Medieval Latin should begin. Being a written language, Late Latin is not the same as Vulgar Latin. The latter served as ancestor of the Romance languages. Although Late Latin reflects an upsurge of the use of Vulgar Latin vocabulary and constructs, it remains largely classical in its overall features, depending on the author who uses it. Some Late Latin writings are more literary and classical, but others are more inclined to the vernacular. Also, Late Latin is not identical to Christian patristic Latin, used in the theological writings of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dingir
''Dingir'' (, usually transliterated DIÄœIR, ) is a Sumerian word for "god" or "goddess". Its cuneiform sign is most commonly employed as the determinative for religious names and related concepts, in which case it is not pronounced and is conventionally transliterated as a superscript "d" as in e.g. dInanna. The cuneiform sign by itself was originally an ideogram for the Sumerian word ''an'' ("sky" or "heaven");Hayes, 2000 its use was then extended to a logogram for the word ''diÄir'' ("god" or "goddess")Edzard, 2003 and the supreme deity of the Sumerian pantheon ''An'', and a phonogram for the syllable . Akkadian took over all these uses and added to them a logographic reading for the native '' ilum'' and from that a syllabic reading of . In Hittite orthography, the syllabic value of the sign was again only ''an''. The concept of "divinity" in Sumerian is closely associated with the heavens, as is evident from the fact that the cuneiform sign doubles as the ideogram f ...

Home Run
In baseball, a home run (abbreviated HR) is scored when the ball is hit in such a way that the batter is able to circle the bases and reach home plate safely in one play without any errors being committed by the defensive team. A home run is usually achieved by hitting the ball over the outfield fence between the foul poles (or hitting either foul pole) without the ball touching the field. Far less common is the "inside-the-park" home run where the batter reaches home safely while the baseball is in play on the field. When a home run is scored, the batter is credited with a hit and a run scored, and a run batted in ( RBI) for each runner that scores, including himself. Likewise, the pitcher is recorded as having given up a hit and a run, with additional runs charged for each runner that scores other than the batter. Home runs are among the most popular aspects of baseball and, as a result, prolific home run hitters are usually the most popular among fans and consequently th ...

Babe Ruth
George Herman "Babe" Ruth Jr. (February 6, 1895 – August 16, 1948) was an American professional baseball player whose career in Major League Baseball (MLB) spanned 22 seasons, from 1914 through 1935. Nicknamed "the Bambino" and "the Sultan of Swat", he began his MLB career as a star left-handed pitcher for the Boston Red Sox, but achieved his greatest fame as a slugging outfielder for the New York Yankees. Ruth is regarded as one of the greatest sports heroes in American culture and is considered by many to be the greatest baseball player of all time. In 1936, Ruth was elected into the Baseball Hall of Fame as one of its "first five" inaugural members. At age seven, Ruth was sent to St. Mary's Industrial School for Boys, a reformatory where he was mentored by Brother Matthias Boutlier of the Xaverian Brothers, the school's disciplinarian and a capable baseball player. In 1914, Ruth was signed to play Minor League baseball for the Baltimore Orioles but was soon sold ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

World Record
A world record is usually the best global and most important performance that is ever recorded and officially verified in a specific skill, sport, or other kind of activity. The book ''Guinness World Records'' and other world records organizations collates and publishes notable records of many. One of them is the World Records Union that is the unique world records register organization recognized by the Council of the Notariats of the European Union. Terminology In the United States, the form World's Record was formerly more common. The term The World's Best was also briefly in use. The latter term is still used in athletics events, including track and field and road running to describe good and bad performances that are not recognized as an official world record: either because it is not an event where the IAAF tracks the record (e.g. the 150 m run or individual events in a decathlon), or because it does not fulfill other rigorous criteria of an otherwise qualifying event (e. ...

Intelligence And Security Committee Russia Report
"The Russia report" is the report of the British Intelligence and Security Committee of Parliament (ISC) into allegations of Russian interference in British politics, including alleged Russian interference in the 2016 Brexit referendum and the 2014 Scottish independence referendum. The committee completed the report in March 2019 and it was published in July 2020, after claims were made that delays to its publication were due to government machinations. According to the report, there is substantial evidence that Russian interference in British politics is commonplace. Inquiry The inquiry began in November 2017, and a 50-page report was completed in March 2019. The report thereafter went through a process of redaction by intelligence and security agencies and was sent to Prime Minister Boris Johnson on 17 October 2019.
