Welcome to Cal Poly's "Puzzle of the Week". On most Fridays during each academic quarter I will post a mathematical problem -- these problems can be found above. If you would like to submit a solution to the current puzzle please send it to me before the next Friday. You can send me an email at sherman1 (followed with calpoly.edu) or find my contact details on my homepage (link above).

Submissions are welcome from anybody. Complete and correct solvers will be recognized in the weekly email (contact me if you are not on the puzzle email list and would like to be added). See below for an archive of old problems and their solutions.

About the background image: Cal Poly math and physics major Alex Gerber sent me this photo of his whiteboard after solving puzzle #020.
