In string theory, the worldsheet is a two-dimensional manifold which describes the embedding of the string in spacetime. String theory is a still-developing scientific approach to Theoretical physics, whose original building blocks are one-dimensional extended objects called strings A manifold is a mathematical space in which every point has a neighborhood which resembles Euclidean space, but in which the global structure may be SpaceTime is a patent-pending three dimensional graphical user interface that allows end users to search their content such as Google Google Images Yahoo! YouTube eBay Amazon and RSS It is a direct generalization of the familiar worldline of a particle in special and general relativity. In physics the world line of an object is the unique path of that object as it travels through 4- Dimensional Spacetime. Special relativity (SR (also known as the special theory of relativity or STR) is the Physical theory of Measurement in Inertial General relativity or the general theory of relativity is the geometric theory of Gravitation published by Albert Einstein in 1916
The type of string, the geometry of the spacetime in which it propagates, and the presence of long-range background fields (such as gauge fields) are encoded in a conformal field theory defined on the worldsheet. Gauge theory is a peculiar Quantum field theory where the Lagrangian is invariant under certain transformations A conformal field theory (CFT is a Quantum field theory (or Statistical mechanics model at the Critical point) that is Invariant under For example, the bosonic string in 26-dimensional Minkowski space has a worldsheet conformal field theory consisting of 26 free scalar fields. Bosonic string theory is the original version of String theory, developed in the late 1960s In Physics and Mathematics, Minkowski space (or Minkowski spacetime) is the mathematical setting in which Einstein's theory of Special relativity In Mathematics and Physics, a scalar field associates a scalar value which can be either mathematical in definition or physical, to every point Meanwhile, a superstring worldsheet theory in 10 dimensions consists of 10 free scalar fields and their fermionic superpartners. See also String theory Superstring theory is an attempt to explain all of the particles and Fundamental forces of nature in one theory by modelling In Particle physics, fermions are particles which obey Fermi-Dirac statistics; they are named after Enrico Fermi. In Particle physics, supersymmetry (often abbreviated SUSY) is a Symmetry that relates elementary particles of one spin to another particle that
