What do Pi Day and San Francisco have in common? The first official Pi Day was organized by San Francisco’s “Prince of Pi” Larry Shaw, a physicist at The Exploratorium in 1988.
Pi Day is this Thursday, March 14, 2013. Pi Day is an annual celebration of the mathematical constant (pi) which is the ratio of a circle’s circumference to its diameter, an approximation equal to 3.14. Pi Day is observed on March 14 because of the date’s representation as 3/14 in month/day date format. March 14 also happens to be Albert Einstein’s birthday.
There are many ways to celebrate Pi Day from eating pie to walking in circles with fellow pi fans to hosting an Einstein look-alike contest. In the past, the Massachusetts Institute of Technology has even mailed out its application decision letters to prospective students for delivery on March 14.
Come on out and join fans of pi at Pi Day celebrations all over San Francisco.
The Exploratorium- Home to the first Pi Day, join staff and pi fans at the 25th annual celebration. To honor Pi Day, there will be pi-related activities, slices of pie, a Pi Parade, and a ceremonious installation of the Pi Shrine at the new Exploratorium location at Pier 15. To top off the pi festivities, five synchronized aircraft will skywrite the first 1,000 numbers of pi’s sequence in the sky above the museum. The pi party takes place from noon until 3 p.m. and is free to the public.
