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"Brick" is a slang term almost always used to refer to large, outdated bar-type phones, typically early mobile phones with large batteries and electronics.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.
Volcán Barú
The Volcán Barú (also Volcán de Chiriqui) is an active stratovolcano and the tallest mountain in Panama, at 3,474 metres (11,398 ft) high. It lies about 35 km off the border of Costa Rica.
Due to its height and Panama's relatively short width, it is possible (though relatively rare) to see both the Pacific Ocean and Caribbean Sea from Volcán Barú's peak on a clear day.
Geography
The small town of El Volcan at the base of El Baru sits on the remnants of a huge lahar that appears to have breached the caldera. A small river has eroded the lahar exposing an ancient forest below dated to about 1000 years old (Stewart, pers. communication).
Volcán Barú is surrounded by a fertile area of cool highlands drained by the Chiriquí Viejo and Caldera Rivers. The towns of Volcán and Cerro Punta can be found on its western side, while Boquete is on the eastern flank.
The occasional fall of hail or ice pellets has been reported on the summit, where the minimum temperature can be below 0 °C (32 °F) and the formation of frost is frequent during the dry season. The peak is host to a large installation of broadcast towers.

BASIC 8
BASIC 8 (or BASIC 8.0) — "The Enhanced Graphics System For The C128" — developed by Walrusoft of Gainesville, Florida and published in 1986 by Patech Software of Somerset, New Jersey, USA, was an extension of Commodore's BASIC 7.0 for the C128 home/personal computer. BASIC 8.0 provided commands lacking in BASIC 7.0 to generate (color) graphics in the C128's high-resolution 80-column mode (640×200 pixels) for RGB monitors.
The BASIC 8 package was developed by Walrusoft's Louis Wallace and David Darus, with contributions from Ken French (printer drivers) and indirectly from Richard Rylander (who allowed his 3D solids commands for the C64, originally published in Dr. Dobb's Journal, to be converted to the C128's hi-res mode).
Background and description
The problem
One of the primary critiques of Commodore's computers was that their BASIC programming language dialects lacked easy sound, graphics, and input device commands, like their competitors in the Apple II and Atari 8-bit families – requiring obscure PEEK and POKE sequences, or machine language routines, to generate high-resolution graphics, sound and music, or read from joysticks and paddles. The BASIC 2.0 of the Commodore 64, totally devoid of sound and graphics commands, induced the development of many third-party language extensions, such as Simons' BASIC, enabling non-expert users to enter the world of computer graphics.

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.
