Unfortunately, after reading the book, the previous question becomes clear "Who worse than Cedric Villani?". The book is elitist, delighting the author has to tell his invitations to the most prestigious universities. We do not learn much about the resolution process of a mathematical enigma, the various emails between the teacher and his colleague bringing nothing apart an impenetrable jargon for non-mathematicians. The "explanations" about the work of Villani has summarize statements of theorems. In English! Because yes, Mr. Villani is not afraid to exclude readings that would not have much culture itself ...
In short, once the book closes, we know absolutely nothing more to mathematics ... Worse, the reader is consolidating in the idea that mathematics is an elitist science, made by funny people that never go out of their ivory towers. A eviter!
