Time: 1:00 – 3:30 pm
Come visit us on March 14 (Pi Day) when we open our doors to the public for free.
Welcome to the 26th annual Pi Day, the mathematical holiday founded at the Exploratorium and celebrated by number lovers around the world. To honor the never-ending number 3.14159… (and Einstein’s birthday), we’ll serve up ?-themed activities, rituals, antics, and plenty of pie. Find out what’s so special about this famous mathematical constant, and take your (decimal) place in our annual march to the Pi Shrine!
Note: Entry is subject to capacity; admission is not guaranteed. We don’t accept group or field trip reservations; group entry is discouraged due to large crowds. Finally, please note that food and drinks are not allowed in the galleries.
