Stanford math professor Keith Devlin talks about two new books that call into question the entire idea of string theory. The theory states that tiny vibrating strings make up everything, but some ...

String theorists are shifting focus to solve some rather sticky problems in physics. Over the past few years, string theory has been less about trying to find a unifying description of all forces and ...

Moduli spaces form the mathematical framework for categorising the diverse solutions characteristic of string theory, providing a systematic means to parameterise the various vacuum configurations ...
