Euromaths: Giovanni Forni - Maths on the Move

We love a game of billiards — or at least the mathematical version of it. It's a dynamical system that's just about basic enough to study but still poses lots of open questions. In this episode of Maths on the Move we talk to Giovanni Forni about chaos, periodicity and the many things we still hope to learn about billiards. We met Giovanni at the European Congress of Mathematics (ECM) in summer this year, which we attended with kind support of the <a href='https://lms.ac.uk/'>London Mathematical Society</a>. See here for more episodes of our <a href='https://plus.maths.org/content/tags/euromaths'>Euromaths</a> series which reports on the ECM.
