Title: Irreversibility for a hard sphere gas (Second Phillips Lecture)
Consider a system of small hard spheres, which are initially (almost) independent and identically distributed. Then, in the low density limit, their empirical measure
1N ∑ Ni = 1δxi(t),vi(t) converges almost surely to a non reversible dynamics, described by the Boltzmann equation.
