3.14: Celebrating Pi Day

Pi Day celebrations* take place, appropriately enough, on March 14. For a glimpse of activities highlighting the enduring fascination of the digits of pi (the ratio of a circle's circumference to its diameter), take a look at the Exploratorium's Web pages devoted to pi, then sample the following links to other weird and wonderful pi pages.

The MAA is collecting pi-related photos for our gallery. Send your pi-related photos with a brief description to editor@maa.org
