Pi Day 2015

March 20, 2015 • 0:30
Relive our 27th annual Pi Day! We celebrated this never-ending number (3.14159 . . .)—and Einstein's birthday, too—with pi-related activities and, of course, plenty 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.
