In this video, we explore the relationship between string theory and quantum field theory (QFT). QFT is a mathematical framework that describes nearly all particles and forces in the universe but ...

Physicists looking for a way to test their theory about strings might make more progress if they tangle them up. String theory — equations that aspire to explain all of nature’s particles and forces — ...

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 ...
