Department of Physics Colloquium

Virtual Event

General Physics Colloquium, Professor David Tong, DAMTP, University of Cambridge

Host: Tom Hartman

Title:  Are we Living in the Matrix?

Abstract:  No. Obviously not. It's a daft question. But, buried underneath this daft question is an extremely interesting one: is it possible to simulate the known laws of physics on a computer? Remarkably, there is a mathematical theorem, due to Nielsen and Ninomiya, that says the answer is no. I'll explain this theorem, the underlying reasons for it, and some recent work attempting to circumvent it.
