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. [2] The corresponding object of arbitrary dimension p is called a p-brane, a term coined by M. J. Duff et al. in 1988. [3]
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 nature, thus solving the hierarchy problem. In the brane picture, the electromagnetic , weak and strong nuclear force are localized on the brane, but gravity has no such constraint and ...
In physics, Randall–Sundrum models (also called 5-dimensional warped geometry theory) are models that describe the world in terms of a warped-geometry higher-dimensional universe, or more concretely as a 5-dimensional anti-de Sitter space where the elementary particles (except the graviton) are localized on a (3 + 1)-dimensional brane or branes.
Sze-Hoi Henry Tye (Chinese: 戴自海; born 1947 in Shanghai, China) is a Chinese-American cosmologist and theoretical physicist most notable for proposing that relative brane motion could cause cosmic inflation as well as his work on superstring theory, brane cosmology and elementary particle physics. He had his primary and secondary school ...
Physlets are physics applets that are free for non-commercial use and were created by the same team as the Open Source Physics Project. Since their creation at Davidson College in 1998, over 2,000 individual exercises have been created using Physlets for the teaching and learning of astronomy and physics on a variety of levels and a variety of ...
Polchinski's contributions to D-brane physics were a primary trigger of the 2nd superstring revolution and the physics of holographic gauge-gravity dualities. After co-discovering D-branes in 1989, his 1995 work conjectured and partially demonstrated the equivalence between D-branes and black p-branes.

Step is based on bodies and forces placed by the user: Bodies range from tiny particles to huge polygons, and each body has unique properties that influence the outcome of the simulation, such as mass and velocity, and their derivations such as kinetic energy.
