## 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.
