What is the formula for string theory?
The Hamiltonian of the closed string, provided by the quantum theory, yields a formula for the mass-squared M 2 M^2 M2 of the closed string in terms of these “number operators” [1]: M 2 = 2 α ′ ( N + N ~ − 2 ) .
What maths is required for string theory?
String theorists need to know algebraic geometry , algebraic topology , moduli spaces , characteristic classes etc.
Can string theory be solved?
The mathematics necessary to solve the theory have not yet been discovered.) Because string theory has near-miraculous breakthroughs every 8 to 10 years, we can expect 2 more breakthroughs in the theory before 2020, and hence might be able to solve this theory by then.
Who wrote The God Equation?

How can I study string theory?
First try to learn advanced mathematics like Calculus, Linear Algebra, complex analysis etc along with advanced physics. Learn Quantum Mechanics and Relativity(you need to be adept in it as though it is the back of your hand). Then slowly watch intro videos on String theory, understand them thoroughly.
What is wrong with string theory?
The internal problems of the theory are even more serious after another decade of research. These include the complexity, ugliness and lack of explanatory power of models designed to connect string theory with known phenomena, as well as the continuing failure to come up with a consistent formulation of the theory.
What is the basic equation of string theory?
$\\begingroup$String theory is formulated using Feynman’s sum over history formalism. The basic equation is just the path integral. The thing that makes strings difficult, in some sense, is that we don’t understand very well what variables we should be using in this path integral.$\\endgroup$ – user1504 Apr 24 ’13 at 19:16 Add a comment | 6
What is a string in physics?
A string is a special case of a p-brane, where a p-brane is a pdimensional object moving through a D(D≥p) dimensional spacetime. For example: •a 0-brane is a point particle, •a 1-brane is a string, •a 2-brane is a membrane . Before looking at strings, let’s review the classical theory of 0-branes, i.e. point particles.

What are the best books to learn about string theory?
We have also drawn on some ideas from the books String Theory and M-Theory (Becker, Becker and Schwarz), Introduction to String Theory (Polchinski), String Theory in a Nutshell (McMahon) and Superstring Theory (Green, Schwarz and Witten), along with the lecture notes of David Tong, sometimes word-for-word.
