Cédric Villani is a French mathematician working primarily on the theory of partial differential equations involved in statistical mechanics, specifically the Boltzmann and Vlasov equations. He has worked on the theory of optimal transport and its applications to differential geometry. He is currently the director of Institut Henri Poincaré in Paris and Professor at the university of Lyon. He was awarded the Fields Medal in 2010.


"When the Earth was too young for Darwin": The age of the Earth has been a much debated subject for hundreds of years, and especially at the end of the nineteenth century, when the mathematics-based theories which were prevailing among physicists were in open conflict with evolutionary theories. Through this story we shall think about the status of mathematics in interaction with other sciences.
