3.141592...: Celebrating Pi Day

Pi Day celebrations take place, appropriately enough, on March 14. What started as a celebration with free Pi pie and math activities on college campuses has since been officially recognized by the 111th U.S. Congress as a national day of appreciation and awareness of the Greek symbol Pi (Bill H.RES.224).

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 [email protected].
