Pi Day

For math lovers, it's a chance to celebrate Pi, one of the most important numbers ever, representing the ratio of a circle's circumference to its diameter.

The Exploratorium said it added a celebration of Einstein's life as part of its Pi Day activities after Shaw's daughter, Sara, realized the coincidence. The museum said Shaw led Pi Day parades there every year until his passing in 2017. Albert Einstein was born on this day in 1879. Although Pi is typically rounded up to 3.14, it can go on forever.
