Celebration of Mind

Why the Celebration?

Martin Gardner was a prolific author who pursued a playful and fun approach to Mathematics, Science, Art, Magic, Puzzles and other fascinating topics. His tradition has been continued in Celebration of Mind events held at numerous locations all over the world.

Included on this website are samplings and reports of some of the Celebration of Mind events which occurred in 2010 through 2013. Each year, these events constitute a global gathering.

Our fifth annual Celebration of Mind events will occur in October 2014, coincident with the centennial of Martin Gardner's birth. We encourage you to host a local Celebration of Mind event, and we encourage everyone to bring a magic trick, puzzle, recreational mathematics problem or story about Martin to share.

The Current Column

These seasonal guest columns will cover Martin's usual subjects: Math, Art, Puzzles, Magic, Skepticism, Science, Philosophy, and maybe an occasional visit from Dr Matrix. Each column will pose at least one problem to be solved or an activity that requires making something.

This inaugural column is about Squaring the Square (a pun on Squaring the Circle). It reviews the problem, cites plenty of references, and adds a little art to it.

Suggestions for a better name for the column are welcome!


Stories of all kinds! Interviews, Tours, a feature story, you name it. Our first story will be out in October, unless we have one contributed for September.

Contributions for future stories are welcome at any time. There are no guidelines other than that the story should be from, or relating to, Celebration of Mind, or Martin Gardner.
