**Abstract:** I plan to talk about two puzzles with very elegant mathematical solutions. I would encourage you to think about (but not Google!) these puzzles, particularly the easier version of the first puzzle, before the talk. All of them can be found in the attachment below. We'll also need volunteers for a demonstration on Friday, so if you'd like to help please email undergradseminar@math.illinois.edu. For Zoom info, please email undergradseminar@math.illinois.edu
