224 - Peter Woit: String Theory and the Crisis in Physics

Patreon: https://bit.ly/3v8OhY7

Peter Woit is a senior lecturer in the Department of Mathematics at Columbia University, where he researches quantum field theory and quantum gravity. Peter is one of the most well-known critics of string theory, and in this episode he and Robinson discuss his work and research in the area, which is encapsulated in his book Not Even Wrong: The Failure of String Theory and the Search for Unity in Physical Law (Basic Books, 2007), as well as his website by the same name. More particularly, they talk about the standard model of particle physics, the problem of quantum gravity, the main figures in string theory, the arguments for and against this approach to physics, its many alleged failures, and the future of research in the area.
