Larry Shaw created Pi Day in 1989. The holiday was celebrated at the San FranciscoExploratorium, where Shaw worked as a physicist, with staff and public marching around one of its circular spaces, then consuming fruit pies. The Exploratorium continues to hold Pi Day celebrations.
There are many ways of celebrating Pi Day. Some of them include eating pie (pi and pie being homophones) and discussing the relevance of π.
It’s also Albert Einstein’s birthday! Down in Princeton, they marked the event with a weekend-long celebration of math and science.
