25th Annual Pi Day
Thursday, March 14, 2013 | 1:00–3:00 p.m.
Location: In front of Pier 15
Join us on Thursday, March 14, 2013, for the 25th anniversary of Pi Day. Founded by Exploratorium physicist and “Prince of Pi” Larry Shaw, this sublimely irrational holiday is celebrated by number lovers around the world. Our festivities take place outdoors from 1:00 to 3:00 p.m. in the Pier 15 Plaza, weather permitting, and are free and open to all.
To honor the never-ending number π (3.14159 . . . ), we’ll serve up slices of pie, share pi-related activities, host a Pi Parade, and ceremoniously install our new Pi Shrine into a fittingly circular site outside Pier 15.
In addition, we are excited to present Pi in the Sky by ISHKY in collaboration with AirSign. At 10,000 feet above our new building, a team of five synchronized aircraft equipped with dot-matrix technology will skywrite the first 1,000 digits of Pi’s infinite sequence (weather permitting), offering an ephemeral, elevated experience of the famous transcendental number.
No public restrooms at the museum will be available during this event; however, all Piers to the north and south of the Exploratorium on the Embarcadero have public restrooms.
