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.
This talk will be given via Zoom, and the link is emailed to the Physics listserv the week of the talk. If you are not on the listserv, please contact Sue Sullivan at email@example.com by Monday at 3:00 pm to request the link.
