MAA AMS Joint Meeting

I took a day off today to go down to the MAA AMS Joint Math Meeting.  Unlike the SIAM meetings this one has a liberal arts flavor to it.

This is how Google works.

Depth-first and Breadth-first search trees from the Botanica Mathematica Project (guess which is which :D )

Most talks I went to revolved around permutations on a pattern or thoughts on teaching. By far my favorite was that by Karl Scha er Dances of Heavenly Bodies: Dance, N-body Choreographies, and Change Ringing.

And I will end with the following quote from the keynote talk on Erdös:

Six is a perfect number in itself, and not because God created all things in six day; rather the converse is true -- God created all things in six days because the number is perfect.

-- St Augustine
