Welcome to our 27th annual Pi Day! Help us celebrate this never-ending number (3.14159 . . .) and Einstein's birthday as well. On the afternoon of Saturday, March 14, 2015, participate in pi-related activities and enjoy a piece of pie.
Founded at the Exploratorium by our own Prince of Pi, physicist Larry Shaw, Pi Day has become an international holiday, celebrated live and online all around the world.
Meet Pi Day founder Larry Shaw, and join hosts Ron Hipschman and Lori Lambertson to find out what’s so special about pi—the irrational number that results from dividing the circumference of a circle by its diameter. Learn the history of pi and how pi is calculated, be entertained by pi limericks, and see a cool pi demo. Pie.
