Arthur Lubin is a Professor of Applied Mathematics at the Illinois Institute of Technology. (Actually, he works in Pure, not Applied, Mathematics, but the details of the apparent inconsistency are not important here.) If you haven’t heard of IIT, that’s not surprising. It’s a small (6,500 students), prestigious technical school, situated in the heart of the windy city (Chicago). Very much in keeping with what has always been Arthur’s persona of striving for excellence without seeking notoriety.
