The Great Rift Valley is a series of contiguous geographic trenches, approximately 7,000 kilometres (4,300 mi) in total length, that runs from the Beqaa Valley in Lebanon which is in Asia to Mozambique in Southeast Africa. While the name continues in some usages, it is rarely used in geology as it is considered an imprecise merging of separate though related rift and fault systems.
In mathematics, a Lie algebra is a vector space together with an operation called the Lie bracket, an alternating bilinear map , that satisfies the Jacobi identity. The vector space together with this operation is a non-associative algebra, meaning that the Lie bracket is not necessarily associative.
In mathematics, a Lie group is a group that is also a differentiable manifold. A manifold is a space that locally resembles Euclidean space, whereas groups define the abstract, generic concept of multiplication and the taking of inverses (division). Combining these two ideas, one obtains a continuous group where points can be multiplied together, and their inverse can be taken. If, in addition, the multiplication and taking of inverses are defined to be smooth (differentiable), one obtains a Lie group.
In mathematics and abstract algebra, group theory studies the algebraic structures known as groups. The concept of a group is central to abstract algebra: other well-known algebraic structures, such as rings, fields, and vector spaces, can all be seen as groups endowed with additional operations and axioms. Groups recur throughout mathematics, and the methods of group theory have influenced many parts of algebra. Linear algebraic groups and Lie groups are two branches of group theory that have experienced advances and have become subject areas in their own right.
A strait is a naturally formed, narrowing, typically navigable waterway that connects two larger bodies of water. The surface water generally flows at the same elevation on both sides and through the strait in either direction. Most commonly it is a channel of water that lies between two land masses. Some straits are not navigable, for example because they are too shallow, or because of an unnavigable reef or archipelago. Straits are also known to be loci for sediment accumulation. Usually, sand-size deposits occur on both the two opposite strait exits, forming subaqueous fans or deltas.
The trachea, also known as the windpipe, is a cartilaginous tube that connects the larynx to the bronchi of the lungs, allowing the passage of air, and so is present in almost all air-breathing animals with lungs. The trachea extends from the larynx and branches into the two primary bronchi. At the top of the trachea the cricoid cartilage attaches it to the larynx. The trachea is formed by a number of horseshoe-shaped rings, joined together vertically by overlying ligaments, and by the trachealis muscle at their ends. The epiglottis closes the opening to the larynx during swallowing.
The Western Hemisphere is the half of Earth which lies west of the prime meridian and east of the antimeridian. The other half is called the Eastern Hemisphere. In geopolitical terms, the context in which the term is most often used, the Encyclopedia Britannica defines it as "North and South America and the surrounding waters. Longitudes 20°W and 160°E are often considered its boundaries." It may be used in a cultural or geopolitical sense as a synonym for the "New World".
A sex position is a position of the body that people use for sexual intercourse or other sexual activities. Sexual acts are generally described by the positions the participants adopt in order to perform those acts. Though sexual intercourse generally involves penetration of the body of one person by another, sex positions commonly involve penetrative or non-penetrative sexual activities.
A lie is an assertion that is believed to be false, typically used with the purpose of deceiving someone. The practice of communicating lies is called lying. A person who communicates a lie may be termed a liar. Lies may serve a variety of instrumental, interpersonal, or psychological functions for the individuals who use them.
In mathematics, a simple Lie group is a connected non-abelian Lie group G which does not have nontrivial connected normal subgroups. The list of simple Lie groups can be used to read off the list of simple Lie algebras and Riemannian symmetric spaces.
In the mathematical discipline of linear algebra, a triangular matrix is a special kind of square matrix. A square matrix is called lower triangular if all the entries above the main diagonal are zero. Similarly, a square matrix is called upper triangular if all the entries below the main diagonal are zero.
Cheat is a card game where the players aim to get rid of all of their cards. It is a game of deception, with cards being played face-down and players being permitted to lie about the cards they have played. A challenge is usually made by players calling out the name of the game, and the loser of a challenge has to pick up every card played so far. Cheat is classed as a party game. As with many card games, cheat has an oral tradition and so people are taught the game under different names.
Doab is a term used in South Asia for the tract of land lying between two confluent rivers. It is similar to an interfluve. In the Oxford Hindi-English Dictionary, R. S. McGregor defines it as from Persian do-āb "a region lying between and reaching to the confluence of two rivers ."
Elfen Lied is a Japanese manga series written and illustrated by Lynn Okamoto. It was originally serialized in Shueisha's Weekly Young Jump from June 2002 to August 2005, with the 107 chapters collected into twelve tankōbon volumes. Elfen Lied revolves around the interactions, views, emotions, and differences between human beings and the Diclonii, a mutant species similar to humans infected by a deadly disease in build but distinguishable by two horns on their heads and "vectors", transparent telekinetically controlled arms that have the power to manipulate and cut objects within their reach. The series is centered on the teenage Diclonius girl "Lucy" who was severely abused by human beings and subsequently wants to murder them all as revenge.
In wrestling a pin is achieved by holding an opponent's shoulders to the mat for a three count. Pinfall is the term used in professional wrestling which is a way to win the match for that person or team.
Kapurthala district is a district of Punjab state in northern India. The city of Kapurthala is the district headquarters.
Gjende is a lake in the Jotunheimen mountains in Norway's Jotunheimen National Park. The proglacial lake shows typical characteristics of glacial formation, being long and narrow, with steep walls—18 km in length and only 1.5 km in width at the broadest point. Gjende has a characteristic light-green color resulting from the large quantity of rock flour which is discharged into the Gjende by the Muru river. The river Sjoa provides the outlet from Gjende at Gjendesheim, and flows eastward into the Gudbrandsdalslågen river.
Representation theory is a branch of mathematics that studies abstract algebraic structures by representing their elements as linear transformations of vector spaces, and studies modules over these abstract algebraic structures. In essence, a representation makes an abstract algebraic object more concrete by describing its elements by matrices and their algebraic operations. The theory of matrices and linear operators is well-understood, so representations of more abstract objects in terms of familiar linear algebra objects helps glean properties and sometimes simplify calculations on more abstract theories.
PolitiFact.com is an American nonprofit project operated by the Poynter Institute in St. Petersburg, Florida, with offices there and in Washington, D.C. It began in 2007 as a project of the Tampa Bay Times, with reporters and editors from the newspaper and its affiliated news media partners reporting on the accuracy of statements made by elected officials, candidates, their staffs, lobbyists, interest groups and others involved in U.S. politics. Its journalists evaluate original statements and publish their findings on the PolitiFact.com website, where each statement receives a "Truth-O-Meter" rating. The ratings range from "True" for statements the journalists deem as accurate to "Pants on Fire" for claims the journalists deem as false or ludicrous.
Big Little Lies is an American drama television series based on the 2014 novel of the same name by Liane Moriarty. Created and written by David E.
