This tragic episode was the last event in a life which was so full of amazing events that Nash became an icon of human genius, recipient of the Nobel Prize and hero of a Hollywood movie looking at his life marked by mental illness. But most of all, Nash was a prophet who founded several new chapters of game theory and geometric analysis in just a few revolutionary contributions that seemed to come from nowhere. Fields medal winner, Cédric Villani takes us through this very special world of mathematical creation. Cédric Villani is a French mathematician who works primarily on partial differential equations, Riemannian geometry and mathematical physics. He was awarded the prestigious Fields Medal in 2010 – an award often viewed as the highest honour a mathematician can receive. He is a member of the Science and Technology Advisory Council and DIrector of the Institut Henri Poincaré.
