The mathematics of bats by Cédric Villani Conference What can mathematics be used for when we are interested in spiders or bats? Website: https://www.unistra.fr Knowledge(s): https://savoirs.unistra.fr Facebook: / unistra Instagram: / unistraofficiel Twitter: / unistra Youtube: / unistra Cédric Villani met high school students at the University of Strasbourg for a conference with a surprising and poetic title: "The mathematics of bats". We thought Cédric Villani was more of a spider lover - he wears one as a brooch on his suit - apparently, it is not an exclusive passion... We will see in this conference how we find concepts, mathematical ideas in many things that are familiar to us. And Cédric Villani answers the question more precisely: what can mathematics be used for when we are interested in animals? To spiders or bats... For several years now, Cédric Villani, a mathematician who won the Fields Medal in 2010, has been involved in an activist approach to meetings with young people to restore the image of maths and try to combat the disaffection with scientific vocations.
