Welcome to our twenty-fifth annual Pi Day! Help us celebrate this never-ending number (3.14159 . . .) and Einstein's birthday as well. On the afternoon of March 14, 2013, participate in pi-related activities and enjoy a piece of pie. If you can't join us in person, celebrate with us in Second Life. |
| 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. | ||
