Brane (other)
A brane is a spatially extended mathematical concept that appears in M-theory. It may also refer to: * Brane cosmology, several theories in particle physics and cosmology related to superstring theory and M-theory * BRANE (acronym for Bombing Radar Navigation Equipment) - the airborne computer built by IBM in the 1950s for the B-52 strategic bomber * Brane, Cornwall, a hamlet in Cornwall, England, with a chambered tomb known as Brane Barrow * Brane, archaic name of Bordeaux wine producer Château Brane-Cantenac * Brane-Mouton, archaic name of Bordeaux wine producer Château Mouton Rothschild * Branko Oblak (born 1947), Yugoslav/Slovenian football player and manager * Brane Mozetič (born 1958), Slovenian poet and editor See also * Branne (other) *Brain The brain is an organ (biology), organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It consists of nervous tissue and is typically located in the head (cephalizatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brane
In string theory and related theories (such as supergravity), a brane is a physical object that generalizes the notion of a zero-dimensional point particle, a one-dimensional string, or a two-dimensional membrane to higher-dimensional objects. Branes are dynamical objects which can propagate through spacetime according to the rules of quantum mechanics. They have mass and can have other attributes such as charge. Mathematically, branes can be represented within categories, and are studied in pure mathematics for insight into homological mirror symmetry and noncommutative geometry. The word "brane" originated in 1987 as a contraction of " membrane". ''p''-branes A point particle is a 0-brane, of dimension zero; a string, named after vibrating musical strings, is a 1-brane; a membrane, named after vibrating membranes such as drumheads, is a 2-brane. The corresponding object of arbitrary dimension ''p'' is called a ''p''-brane, a term coined by M. J. Duff ''et al. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brane Cosmology
Brane cosmology refers to several theories in particle physics and cosmology related to string theory, superstring theory and M-theory. Brane and bulk The central idea is that the visible, four-dimensional spacetime is restricted to a brane inside a higher-dimensional space, called the "bulk" (also known as "hyperspace"). If the additional dimensions are compact, then the observed universe contains the extra dimension, and then no reference to the bulk is appropriate. In the bulk model, at least some of the extra dimensions are extensive (possibly infinite), and other branes may be moving through this bulk. Interactions with the bulk, and possibly with other branes, can influence our brane and thus introduce effects not seen in more standard cosmological models. Why gravity is weak and the cosmological constant is small Some versions of brane cosmology, based on the large extra dimension idea, can explain the weakness of gravity relative to the other fundamental forces of nat ...

Brane, Cornwall
Brane is a hamlet (place), hamlet southwest of Sancreed in west Cornwall, England, UK. It is in the civil parish of Sancreed. It is noted for the Carn Euny Iron Age site which lies to the north. Other prehistoric sites nearby include the Iron-Age hill fort of Caer Bran, and chambered tomb known as Brane Barrow. References Hamlets in Cornwall Penwith {{Penwith-geo-stub ...
