We will be begin practice sessions for the Putnam exam next week. The Putnam is a nationwide mathematics competition open to all undergraduates, held the first Saturday in December. First prize is a graduate fellowship to Harvard! But the questions are very challenging -- and very cool. Here is a recent sample: "Let f be a real-valued function on the plane such that for every square ABCD in the plane, f(A) + f(B) + f(C) + f(D) = 0. Does it follow that f(P) = 0 for all points P in the plane?" We will have practice sessions for the Putnam exam every Thursday this semester, 5:30 - 7pm in RLM 9.166, starting Thursday Sept 29. Pizza, the dinner of champions, will be served. For more information or to register for the competition, please see Dave Rusin, RLM 9.140
