Persi Diaconis from Stanford University is giving the Loeb Lecture “Adding Numbers and Shuffling Cards” 
4:30-5:30 in Rebstock, Room 215 at Wash U.

Persi is a world class mathematician, who is also famous for giving amazing and accessible talks.  You can either meet us at the talk at Wash U or if you want a ride, you can meet us at 3:30-3:45 in Ritter Lobby.   Note that it is also very easy to get to Wash U by metro.  If you get to Wash U early, then there is tea in Cupples I, room 200 at 3:45. 

Abstract: When numbers are added in the usual way 'carries' occur as you go along. Understanding these carries (how many, where do they occur, if you just had a carry is it more or less likely that there will be a carry in the next place) leads to fascinating corners of mathematics. It turns out that one of these corners has to do with the usual way that we riffle shuffle cards(!). There is a healthy theory of shuffling, and carries and shuffling illuminate each other. I will explain all of this in a non-technical way for a general audience.
