The history of string theory spans several decades of intense research including two superstring revolutions. Through the combined efforts of many researchers, string theory has developed into a broad and varied subject with connections to quantum gravity, particle and condensed matter physics, cosmology, and pure mathematics.
In physics, string theoryis a theoretical frameworkin which the point-like particlesof particle physicsare replaced by one-dimensionalobjects called strings. String theory describes how these strings propagate through space and interact with each other. On distance scales larger than the string scale, a string looks just like an ordinary ...
Gabriele Veneziano (/ ˌvɛnətsiˈænoʊ /; [citation needed]Italian: [venetˈtsjaːno]; born 7 September 1942) [ 1 ] is an Italian theoretical physicist widely considered the father of string theory. [ 2 ][ 3 ] He has conducted most of his scientific activities at CERN in Geneva, Switzerland, and held the Chair of Elementary Particles ...
Holographic principle. The holographic principle is a property of string theories and a supposed property of quantum gravity that states that the description of a volume of space can be thought of as encoded on a lower-dimensional boundary to the region – such as a light-like boundary like a gravitational horizon. [1][2] First proposed by ...
M-theory is a theory in physics that unifies all consistent versions of superstring theory. Edward Witten first conjectured the existence of such a theory at a string theory conference at the University of Southern California in 1995. Witten's announcement initiated a flurry of research activity known as the second superstring revolution.
Website. ias.edu /sns /witten. Edward Witten (born August 26, 1951) is an American theoretical physicist known for his contributions to string theory, topological quantum field theory, and various areas of mathematics. He is a professor emeritus in the school of natural sciences at the Institute for Advanced Study in Princeton. [ 4 ]
String theory further claims that it is through these specific oscillatory patterns of strings that a particle of unique mass and force charge is created (that is to say, the electron is a type of string that vibrates one way, while the up quark is a type of string vibrating another way, and so forth).
Leonard Susskind. Leonard Susskind (/ ˈsʌskɪnd /; born June 16, 1940) [ 2 ][ 3 ] is an American theoretical physicist, Professor of theoretical physics at Stanford University and founding director of the Stanford Institute for Theoretical Physics. His research interests are string theory, quantum field theory, quantum statistical mechanics ...
