Come join Champaign-Urbana’s celebration of the spirit of recreational mathematics and fun math puzzles, and the life of math and science writer Martin Gardner! At the occasion of Gardner’s 100th birthday the University of Illinois will host a dozen local mathematicians and computer scientists who will present math puzzles, logic puzzles, hexaflexagons, magic tricks, visual paradoxes and much more! This event is part of the worldwide event Gathering for Gardner: Celebration of Mind. It is free and open to members of the public of all ages – no math training required to enjoy the puzzles and the mathematics!
