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.
