Mathieu Vidard Mémoires d’une mathématicienne : Yvonne Choquet-Bruhat


Yvonne Choquet-Bruhat : “Dès que ma raison s’est éveillée, j’ai désiré comprendre quelque chose de cet univers étrange où nous vivons, et de ce qu’y font les êtres humains, moi en particulier. J’ai flirté avec des domaines variés de la connaissance : sciences naturelles, physique, histoire, philosophie. Je suis finalement devenue une mathématicienne travaillant sur des problèmes posés par la physique.

The Intrepid Mathematician

What is the connectome?

Networks are everywhere: the roads in cities, links in the web, and the neural pathways in our brains. The science of networks is a trending topic interfacing with many disciplines. Mathematics, as you would expect, plays a major role in understanding the properties, structure, and evolution of networks.

The connectome is a network consisting of the neural pathways within a brain. Think of it as a set of wires linking different regions of the brain with their many diverse functions. Neuroscientists distinguish between white and gray brain matter. White matter is analogous to highways connecting the cities of gray matter.

Andreas Horn Max-Planck-Institute for Human Development, Berlin The human connectome.

Connectomics is fairly recent topic in neuroscience, emerging from the work of Olaf Sporns and Patric Hagmann in 2005. As a new field within neuroscience, it uses tools from mathematics and big data to help map the brain and its various functions, often using MRIs to probe the brain’s…

Meet the 'Lady Gaga' of the maths world, Cédric Villani

Villani has won the Fields Medal, written a comic book and appeared on the covers of French fashion magazines.


At 42, mathematician Cédric Villani is something of a rock star. He is not just a prodigious mathematician – he won the Fields Medal, the most prestigious award in mathematics, in 2010. Since then, he has been travelling across the world to deliver public lectures and to advocate for mathematics in countries without the infrastructure to support it, particularly in Africa. He has also written a comic book in French.

Villani has another claim to fame, in part because of his distinctive personal style, which includes a three-piece suit, a flamboyant cravat knotted into a loose bow and a giant spider brooch. This has won him the unusual second distinction of featuring in photo shoots and on the covers of French fashion magazines.
