Not very piano related, but as Prof Guillaume is a mathematician and Pianoteq is a result of applications of maths and physics, I thought some of you may enjoy this talk by another French mathematician (and Fields medallist!), the brilliant and IMHO very charming Cédric Villani:https://youtu.be/yYwydG_aHPE
If you liked that, be sure to check up the Q&A video as well (link should appear in the RH column).
