THE STRING THEORY

INTRODUCTION String theory is a developing theory in particle physics which attempts to reconcile quantum mechanics and general relativity . String Theory , sometimes called the Theory of Everything, is thought by some to be the unifying field theory Einstein sought before his death. String theory is the first mathematically sound theory that reconciles the world of the infinitesimally small, with the world we know at large. It unites Einstein’s Theory of Relativity with quantum physics and offers a potential explanation for the Big Bang. What's string theory? String theory posits that the electrons and quarks within an atom are not 0-dimensional objects, but rather 1-dimensional oscillating lines ("strings"), possessing only the dimension of length, but not height or width. The theory poses that these strings can vibrate, thus giving the observed particles their flavor , charge , mass and spin. History of String Theory Gabriele Veneziano, a research fello...

|String|---|Theory|

The String Theory is a recent trend or theory is physics which is attempting to formulate a theory to harmonize quantum mechanics and general relativity.It is trying to prove that electrons and quarks in the nucleus are not zero-dimensional,but rather uni-dimensional oscillating lines called strings.It is said to possess only length and no other dimension. This is one of the hottest research going on in the modern day physics.It has originated from the dual-resonance model which was proposed by Gabriele Veneziano in 1969.There are 5 major developed string theories.Each of them differs in the number of dimensions in which the strings developed and their characteristics.All these theories seems to be correct though. Once scientists believed there were 5 superstring theories-Type I,types IIA and IIB and the two heterotic string theories.The thinking was that out of these five candidate theories, only one was the actual correct Theory of Everything .But now it is known that it was naive t...

GRAND UNIFIED THEORY

GUT The term Grand Unified Theory or GUT, refers to any of several similar models in particle physics in which at high energy scales, the three gauge interactions of the Standard Model which define the electromagnetic, weak, and strong interactions, are merged into one single interaction characterized by a larger gauge symmetry and one unified coupling constant rather than three independent ones History : Historically, the first true GUT which was based on the simple Lie group SU(5), was proposed by Howard Georgi and Sheldon Glashow in 1974.The Georgi–Glashow model was preceded by the Semisimple Lie algebra Pati–Salam model by Abdus Salam and Jogesh Pati,who pioneered the idea to unify gauge interactions. Unification of forces and the role of supersymmetry : The renormalization group running of the three-gauge couplings has been found to nearly, but not quite, meet at the same point if the hypercharge is normalized so that it is consistent with SU(5) or SO(10) GUTs,...
