Bar

A bar (also known as a saloon or a tavern or sometimes a pub or club, referring to the actual establishment, as in pub bar or club bar etc.) is a retail business establishment that serves alcoholic beverages, such as beer, wine, liquor, cocktails, and other beverages like mineral water and soft drinks and often sell snack foods, like crisps or peanuts, for consumption on premises. Some types of bars, such as pubs, may also serve food from a restaurant menu.

Bars provide stools or chairs that are placed at tables or counters for their patrons. Some bars have entertainment such as a live band, Bars that offer entertainment or live music are often referred to as music bars, live venues, or nightclubs. Types of bars range from inexpensive dive bars to elegant places of entertainment often accompanying restaurants for dining.

Many bars have a discount period, designated a "happy hour" to encourage off-peak-time patronage. Bars that fill to capacity sometimes implement a cover charge or a minimum drink purchase requirement during their peak hours. Bars may have bouncers to ensure patrons are of legal age, to eject drunk or fighting patrons, and to collect cover charges. Such bars often feature entertainment, which may be a live band, vocalist, comedian, or disc jockey playing recorded music.

Form factor (mobile phones)

The form factor of a mobile phone is its size, shape, and style, as well as the layout and position of its major components. There are three major form factors – bar phones, flip phones, and sliders – as well as sub-categories of these forms and some atypical forms.

Bar

A bar (also known as a slab, block, candybar) phone takes the shape of a cuboid, usually with rounded corners and/or edges. The name is derived from the rough resemblance to a chocolate bar in size and shape. This form factor is widely used by a variety of manufacturers, such as Nokia and Sony Ericsson. Bar type mobile phones commonly have the screen and keypad on a single face. The Samsung SPH-M620 has a unique bar style, offering different devices on either side of the bar: a phone on one side, and a digital audio player on the other. Sony Ericsson also had a well-known 'MarsBar' phone model CM-H333.

Since mid 2010s, almost all the mobile phones come in bar form factor.

Brick

"Brick" is a slang term almost always used to refer to large, outdated bar-type phones, typically early mobile phones with large batteries and electronics. However, "brick" has more recently been applied to older phone models in general, including non-bar form factors (flip, slider, swivel, etc.), and even early touchscreen phones as well, due to their size and relative lack of functionality to newer models. Such early mobile phones, such as the Motorola DynaTAC, have been displaced by newer smaller models which offer greater portability thanks to smaller antennas and slimmer battery packs.

Bar association

A bar association is a professional body of lawyers. Some bar associations are responsible for the regulation of the legal profession in their jurisdiction; others are professional organizations dedicated to serving their members; in many cases, they are both. In many Commonwealth jurisdictions, the bar association comprises lawyers who are qualified as barristers or advocates in particular, versus solicitors (see bar council). Membership in bar associations may be mandatory or optional for practicing attorneys, depending on jurisdiction.

Etymology

The use of the term bar to mean "the whole body of lawyers, the legal profession" comes ultimately from English custom. In the early 16th century, a railing divided the hall in the Inns of Court, with students occupying the body of the hall and readers or benchers on the other side. Students who officially became lawyers crossed the symbolic physical barrier and were "admitted to the bar". Later, this was popularly assumed to mean the wooden railing marking off the area around the judge's seat in a courtroom, where prisoners stood for arraignment and where a barrister stood to plead. In modern courtrooms, a railing may still be in place to enclose the space which is occupied by legal counsel as well as the criminal defendants and civil litigants who have business pending before the court.

Space (mathematics)

In mathematics, a space is a set (sometimes called a universe) with some added structure.

Mathematical spaces often form a hierarchy, i.e., one space may inherit all the characteristics of a parent space. For instance, all inner product spaces are also normed vector spaces, because the inner product induces a norm on the inner product space such that:

where the norm is indicated by enclosing in double vertical lines, and the inner product is indicated enclosing in by angle brackets.

Modern mathematics treats "space" quite differently compared to classical mathematics.

History

Before the golden age of geometry

In the ancient mathematics, "space" was a geometric abstraction of the three-dimensional space observed in the everyday life. Axiomatic method had been the main research tool since Euclid (about 300 BC). The method of coordinates (analytic geometry) was adopted by René Descartes in 1637. At that time, geometric theorems were treated as an absolute objective truth knowable through intuition and reason, similar to objects of natural science; and axioms were treated as obvious implications of definitions.

Five-dimensional space

A five-dimensional space is a space with five dimensions. If interpreted physically, that is one more than the usual three spatial dimensions and the fourth dimension of time used in relativitistic physics. It is an abstraction which occurs frequently in mathematics, where it is a legitimate construct. In physics and mathematics, a sequence of N numbers can be understood to represent a location in an N-dimensional space. Whether or not the actual universe in which we live is five-dimensional is a topic of debate.

Physics

Much of the early work on five dimensional space was in an attempt to develop a theory that unifies the four fundamental forces in nature: strong and weak nuclear forces, gravity and electromagnetism. German mathematician Theodor Kaluza and Swedish physicist Oskar Klein independently developed the Kaluza–Klein theory in 1921, which used the fifth dimension to unify gravity with electromagnetic force. Although their approaches were later found to be at least partially inaccurate, the concept provided a basis for further research over the past century.
