Math professor entertains crowd at UNI's family weekend

Just when I thought Allen Knutson was the center of the math juggling universe, my alma mater represented itself last weekend. I never had class with Dean Franzen, but the UNI math department has always been a source of hidden talents. Dr. John Longnecker, for example, was known to bring his guitar to the last day of classes and sing songs like "500 Miles" except with their metric equivalents.
