épée
The ( or , ), sometimes spelled epee in English, is the largest and heaviest of the three weapons used in the sport of fencing. The modern derives from the 19th-century , a weapon which itself derives from the French small sword. This contains a detailed contempraneous description of the history and form of the sport. As a thrusting weapon, the is similar to a foil (contrasted with a sabre, which is designed for slashing). It has a stiffer blade than a foil. It is triangular in cross-section with a V-shaped groove called a fuller. The also has a larger bell guard and weighs more. The techniques of their use differ, as there are no rules regarding priority and right of way. Thus, immediate counterattacks are a common feature of fencing. In addition, the entire body is a valid target area.

Politics
Politics (from , ) is the set of activities that are associated with making decisions in groups, or other forms of power relations among individuals, such as the distribution of resources or status. The branch of social science that studies politics and government is referred to as political science. It may be used positively in the context of a "political solution" which is compromising and nonviolent, or descriptively as "the art or science of government", but also often carries a negative connotation.. The concept has been defined in various ways, and different approaches have fundamentally differing views on whether it should be used extensively or limitedly, empirically or normatively, and on whether conflict or co-operation is more essential to it. A variety of methods are deployed in politics, which include promoting one's own political views among people, negotiation with other political subjects, making laws, and exercising internal and external force, includ ...

Swordsman
Swordsmanship or sword fighting refers to the skills and techniques used in combat and training with any type of sword. The term is modern, and as such was mainly used to refer to smallsword fencing, but by extension it can also be applied to any martial art involving the use of a sword. The formation of the English word "swordsman" is parallel to the Latin word ''gladiator'', a term for the professional fighters who fought against each other and a variety of other foes for the entertainment of spectators in the Roman Empire. The word ''gladiator'' itself comes from the Latin word ''gladius'', which is a type of sword. European swordsmanship Classical history The Roman legionaries and other forces of the Roman military, until the 2nd century A.D., used the gladius as a short thrusting sword effectively with the ''scutum'', a type of shield, in battle. According to Vegetius the Romans mainly used underhanded stabs and thrusts because one thrust into the gut would kill an enem ...

Battle
A battle is an occurrence of combat in warfare between opposing military units of any number or size. A war usually consists of multiple battles. In general, a battle is a military engagement that is well defined in duration, area, and force commitment. An engagement with only limited commitment between the forces and without decisive results is sometimes called a skirmish. The word "battle" can also be used infrequently to refer to an entire operational campaign, although this usage greatly diverges from its conventional or customary meaning. Generally, the word "battle" is used for such campaigns if referring to a protracted combat encounter in which either one or both of the combatants had the same methods, resources, and strategic objectives throughout the encounter. Some prominent examples of this would be the Battle of the Atlantic, Battle of Britain, and Battle of Stalingrad, all in World War II. Wars and military campaigns are guided by military strategy, wherea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urban Area
An urban area, built-up area or urban agglomeration is a human settlement with a high population density and infrastructure of built environment. Urban areas are created through urbanization and are categorized by urban morphology as cities, towns, conurbations or suburbs. In urbanism, the term contrasts to rural areas such as villages and hamlets; in urban sociology or urban anthropology it contrasts with natural environment. The creation of earlier predecessors of urban areas during the urban revolution led to the creation of human civilization with modern urban planning, which along with other human activities such as exploitation of natural resources led to a human impact on the environment. "Agglomeration effects" are in the list of the main consequences of increased rates of firm creation since. This is due to conditions created by a greater level of industrial activity in a given region. However, a favorable environment for human capital development would al ...

Universe
The universe is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy. The Big Bang theory is the prevailing cosmological description of the development of the universe. According to this theory, space and time emerged together ago, and the universe has been expanding ever since the Big Bang. While the spatial size of the entire universe is unknown, it is possible to measure the size of the observable universe, which is approximately 93 billion light-years in diameter at the present day. Some of the earliest cosmological models of the universe were developed by ancient Greek and Indian philosophers and were geocentric, placing Earth at the center. Over the centuries, more precise astronomical observations led Nicolaus Copernicus to develop the heliocentric model with the Sun at the center of the Solar System. In developing the law of universal gravitation, Isaac Newton built upon Copernicus's wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rationality
Rationality is the quality of being guided by or based on reasons. In this regard, a person acts rationally if they have a good reason for what they do or a belief is rational if it is based on strong evidence. This quality can apply to an ability, as in rational animal, to a psychological process, like reasoning, to mental states, such as beliefs and intentions, or to persons who possess these other forms of rationality. A thing that lacks rationality is either ''arational'', if it is outside the domain of rational evaluation, or '' irrational'', if it belongs to this domain but does not fulfill its standards. There are many discussions about the essential features shared by all forms of rationality. According to reason-responsiveness accounts, to be rational is to be responsive to reasons. For example, dark clouds are a reason for taking an umbrella, which is why it is rational for an agent to do so in response. An important rival to this approach are coherence-based ac ...

Instantaneous Transportation
Teleportation is the theoretical transfer of matter and/or energy from one point to another without traversing the physical space between them. It is a common subject in science fiction and fantasy literature, film, video games, and television. In some situations, teleporting is presented as time traveling across space. The use of matter transmitters in science fiction originated at least as early as the 19th century. An early example of scientific teleportation (as opposed to magical or spiritual teleportation) is found in the 1897 novel ''To Venus in Five Seconds'' by Fred T. Jane. Jane's protagonist is transported from a strange-machinery-containing gazebo on Earth to planet Venus. A common fictional device for teleportation is a "wormhole". In video games, the instant teleportation of a player character may be referred to as a warp.

Economic System
An economic system, or economic order, is a system of production, resource allocation and distribution of goods and services within a society or a given geographic area. It includes the combination of the various institutions, agencies, entities, decision-making processes, and patterns of consumption that comprise the economic structure of a given community. An economic system is a type of social system. The mode of production is a related concept. All economic systems must confront and solve the four fundamental economic problems: * What kinds and quantities of goods shall be produced: This fundamental economic problem is anchored on the theory of pricing. The theory of pricing, in this context, has to do with the economic decision-making between the production of capital goods and consumer goods in the economy in the face of scarce resources. In this regard, the critical evaluation of the needs of the society based on population distribution in terms of age, sex, occupat ...

Government
A government is the system or group of people governing an organized community, generally a state. In the case of its broad associative definition, government normally consists of legislature, executive, and judiciary. Government is a means by which organizational policies are enforced, as well as a mechanism for determining policy. In many countries, the government has a kind of constitution, a statement of its governing principles and philosophy. While all types of organizations have governance, the term ''government'' is often used more specifically to refer to the approximately 200 independent national governments and subsidiary organizations. The major types of political systems in the modern era are democracies, monarchies, and authoritarian and totalitarian regimes. Historically prevalent forms of government include monarchy, aristocracy, timocracy, oligarchy, democracy, theocracy, and tyranny. These forms are not always mutually exclusive, and mixe ...

Eta Boötis
Eta Boötis (η Boötis, abbreviated Eta Boo, η Boo) is a binary star in the constellation of Boötes. Based on parallax measurements obtained during the Hipparcos mission, it is approximately 37 light-years (11 parsecs) distant from the Sun. Since 1943, the spectrum of this star has served as one of the stable anchor points by which other stars are classified. It forms a double star with the star BD+19 2726. As a constituent of a double pair, Eta Boötis is also designated WDS J13547+1824A, with its two components being designated Aa (formally named Muphrid , the traditional name for the entire system) and Ab. (As part of a binary pair, they are also designated Eta Boötis A and B, respectively.) BD +19 2726 is also designated WDS J13547+1824B. Nomenclature ''η Boötis'' ( Latinised to ''Eta Boötis'') is the binary pair's Bayer designation; ''η Boötis A'' and ''B'' those of its two components.
