Public Talk by Marc Henneaux

Gravitation and Quantum Mechanics: the biggest crisis in modern physics?

Abstract:
One of the major challenges of contemporary physics is to reconcile Einstein theory of gravity with quantum mechanics. These two pillars of modern physis, which have a wealth of experimental support, are incompatible in their current formulations. The lecture will illustrate the revolutionary concepts underlying these two theories, as well as the origin of their conflict and the current attempts to build a consistent synthesis of them (among which string theory remains one of the most promising candidates). The idea of "symmetry" will be explained and its importance will be particularly stressed in the pursuit of that goal.
