Formes et courbure

On April 5th, 2013, during the 24th Math en Jean congress in Orsay, I gave a talk on the Gauss-Bonnet formula for an audience of 11-15 years old (interested enough in maths to belong to a math club).

The video below gives an idea if how it went, despite its small size. At the very end of the talk, I showed a video from Hévéa project. Here this video appear only as a couple of images but you can see it on the Hévéa project website.
