San Francisco’s Exploratorium is gearing up for Pi (π) Day on March 14, 2024 from 11am-3pm! The beloved and famous event features math-inspired activities and a high-spirited Pi Procession with free pie for all.
The 2024 festivities include performances from local 12-piece brass band Mission Delirium, pie from Pietisserie, and presentations about Pi and why we celebrate it.
During the Pi Procession at 2pm, a crowd of people carrying digits of Pi will circle the Pi Shrine 3.14 times while dancing along to music from a live brass band. Participants will then sing “Happy Birthday” to Albert Einstein (and Steph Curry) and enjoy a free slice of pie after the parade.
Exploratorium employee and physicist Larry Shaw founded Pi Day back in 1988. It has since grown into a nationwide holiday and was designated as the International Day of Mathematics in 2019. This year marks the Exploratorium’s 36th annual celebration of the holiday.
Pi, denoted by the symbol π, is a mathematical constant referring to the ratio of a circle’s circumference to its diameter. Its decimal representation is infinite and it never enters a pattern, but the first part of Pi is 3.14159… Mathematicians have attempted to calculate it with more and more accuracy over 4,000 years, but the numbers never end!
This is a free celebration with museum admission – Grab tickets to the Exploratorium on March 14, 2024 between 11am-3pm to enjoy Pi Day in all its glory. Find the Exploratorium at Pier 15 of the Embarcadero.
