<p>In the early 1930's, the Ergodic theorems of von Neumann and
Birkhoff put Boltzmann's Ergodic Hypothesis in mathematical terms,
and the natural question was born: is ergodicity the "general
case" among conservative dynamical systems? Oxtoby and Ulam
tackled this question early on and showed that the answer to this
question is "yes" for continuous dynamical systems. The work of
Kolmogorov Arnol'd and Moser beginning in the 1950's showed that
the answer to this question is "no" for $C^\infty$ dynamical
systems. I will discuss recent work with Artur Avila and Sylvain
Crovisier that addresses what happens for $C^1$ dynamical systems.</p>
