There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon.

Functionally the new site is identical to the old one. webteam@gatech.edu

IBM Research runs a mathematical challenge site, called "Ponder This." Every month the site posts a new challenge and reveals the solution for the previous month's riddle. Oded Margalit has been the puzzlemaster since 2005. He will survey some of the riddles over the years and tell some anecdotes about the challenges and the solvers, for example:
Don't worry! No high mathematics knowledge is assumed.
