Impediments to scientific progress

A large part of this work took place during a year when Villani was holed up at the Institute in Princeton, and this is described in detail. Difficult working conditions included lack of access to good bread or cheese, a major reason Villani turned down efforts by Princeton to keep him there and returned to France, where he is now Director of the Institut Henri Poincaré in Paris.
