John Nash, famous for his work in game theory and as the subject of the film *A Beautiful Mind*, has died in a car crash, according to the BBC.

As well as winning the (in memory of but not actually a) Nobel Prize for Economics in 1994, Nash was recently awarded the Abel Prize for his work on nonlinear partial differential equations.
