String field theory is a second-quantised framework that recasts the perturbative dynamics of strings in terms of field-theoretic variables on the space of string configurations. By organising ...

Quantum field theory (QFT) realises particles as excitations of underlying fields that permeate spacetime. By quantising classical gauge and matter fields, QFT unifies quantum mechanics with special ...

In this video, we explore the relationship between string theory and quantum field theory (QFT). QFT is a mathematical ...

String theory has long been presented as physicists' best candidate for describing the fundamental nature of the Universe. Yet, at the beginning of the 21st century, it became apparent that most ...

Scientists seeking the secrets of the universe would like to make a model that shows how all of nature’s forces and particles fit together. It would be nice to do it with Legos. But perhaps a better ...

Does string theory—the controversial “theory of everything” from physics—tell us anything about consciousness and the human brain? If you're enjoying this article, consider supporting our ...
