I’ve been invited to give a talk at The Winter Meeting on Statistical Mechanics in Taxco, Mexico. The meeting will last from January 5th to the 8th of 2010. I hear Taxco is a small cute city in the mountains, a few hours away from Mexico City. I’m very excited about this trip.
You should come too! I promise you will never meet such a fun crowd of Stat Mech Physicists in your life. Make sure you register before November 16th.
