For the elaborated answer, we have to go a little technical. It replaces point-like particles with strings and describes, how these strings interact in space and time.

Superstring theory, a more realistic but mathematically more complicated extension of bosonic string theory, demands the existence of nine spatial dimensions and one time dimension. In the early 1970s, supersymmetry was discovered in the context of string theory, and a new version of string theory called superstring theory (supersymmetric string theory) became the real focus. Using the theory of infinite-dimensional pseudodifferential operators in superspace, a Schrödinger representation is introduced to the theory of bosonic strings (the superstucture emerges under BRST quantization). The Bosonic String Theory was developed in the late 60s and a couple of years later, it was established that it will make sense by keeping it in 26 dimensions. With bosonic string theory, the equations actually demanded a certain number of dimensions to be mathematically consistent. The first is Albert Einstein's general theory of relativity, a theory that explains the force of gravity and the structure of spacetime at the macro-level. Check if you have access via personal or institutional login. Since everyday experience supports the existence of only three spatial dimensions and one time dimension, string theory must explain why extra dimensions are consistent with observation. Even that was easy to understand for most of us as time is also something we can relate to. Required fields are marked *. Volume 1 provides a thorough introduction to the bosonic string, based on the Polyakov path integral and conformal field theory. The 26 dimensions of Closed Unoriented Bosonic String Theory are interpreted as the 26 dimensions of the traceless Jordan algebra J3(O)o of 3x3 Octonionic matrices, with each of the 3 Octonionic dimenisons of J3(O)o having the following physical interpretation: 4-dimensional physical spacetime plus 4-dimensional internal symmetry space; 8 first-generation fermion particles; 8 first … ultra-violet finite, quantum theory of particle interactions and gravity. String theory Vol 1 An introduction to the bosonic string. So, there are things in science which we do not understand at times purely because we do not know the math yet. That’s what we understand, that’s what we can easily visualize. Your email address will not be published. Many calculations are skipped, or just barely given.

This is interesting, as string theory potentially provided infinite answere, not telling which was the right one. So, why are there 26 dimensions in Bosonic String Theory?

It also assumes that you are very comfortable with the language and techniques of non-abelian gauge theories.

We construct the effective action for toroidal compactifications of bosonic string theory from generalized Scherk-Schwarz reductions of double field theory. Havaldar Gyan Bahadur Tamang: – The true hero of Kargil war, Pokhran Nuclear Test II : How India fooled CIA before “Operation Shakti”, Internet mysteries that have left us baffled for years, Musical instruments which supposedly containing magical powers, Dangerous railway routes around the globe, offering extreme adventures. What distinguishes it from other approaches to quantising gravity is that String Theory is currently the only theory that is able to provide a uni ed quantum description of all interactions of Nature, both gravitational and non- Volume 1, first published in 1998, provides a thorough introduction to the bosonic string. Everything is presented with great care, but not always with great detail. Supersymmetry and String Theory Beyond the Standard Model. sigma model, brane. Just remember that it remains theory until it can be proven experimentally, hopefully, without blowing-up the universe. The two volumes that comprise String Theory provide an up-to-date, comprehensive account of string theory. It took me another five minutes to create a symbol (or logo) which fulfills all of the above mentioned requirements. Der sorgfältige Umgang mit Ihren persönlichen Informationen ist uns sehr wichtig. The other is quantum mechanics, a completely different formulation, which uses known probability principles to describe physical phenomena at the micro-level.
