Wandering around New York Times site this morning, I stumbled upon a math column. The column was a short run-- a fifteen part series-- by a professor of applied mathematics from Cornell University. I have not read much of the series so far, but I read the piece on the integral and I found it to be engaging.
Note: I am going up to my Alma Mater tomorrow for a week to see Cerinthus. I will try to keep up with my posting.
