Fields medal winner Cédric Villani takes us through the very special world of mathematical creation of John Nash, who founded several new chapters of game theory and geometric analysis in just a few revolutionary contributions that seemed to come from nowhere. On 23 May 2015, John Forbes Nash tragically died in a taxi accident, just after receiving the most prestigious award that a mathematician can dream of, the Abel Prize. 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. Cédric Patrice Thierry Villani (French: [se.dʁik pa.tʁis tjɛ.ʁi vi.la.ni]; born 5 October 1973) is a French mathematician and politician working primarily on partial differential equations, Riemannian geometry and mathematical physics. He was awarded the Fields Medal in 2010 and he was the director of Sorbonne University's Institut Henri Poincaré from 2009 to 2017. Villani was elected to the National Assembly, the lower house of the French Parliament, during the 2017 legislative election. A member of La République En Marche! he represents Essonne's 5th constituency.[2] He was elected Vice President of the French Parliamentary Office for the Evaluation of Scientific and Technological Choices in July 2017. After attending the Lycée Louis-le-Grand, Villani was admitted at the École Normale Supérieure in Paris and studied there from 1992 to 1996. He was later appointed an assistant professor in the same school. He received his doctorate at Paris Dauphine University in 1998, under the supervision of Pierre-Louis Lions, and became professor at the École normale supérieure de Lyon in 2000. He is now professor at the University of Lyon. He has been the director of Institut Henri Poincaré in Paris since 2009. He has held various visiting positions at Georgia Tech (Fall 1999), the University of California, Berkeley (Spring 2004), and the Institute for Advanced Study, Princeton (Spring 2009)
