larry shaw, the "prince of pi", invented the holiday pi day in 1988 while at the exploratorium. during an off-site staff retreat in 1988, he started talking with his co-workers, like ron hipschman, about the mysteries of mathematical constants. shaw came up with the idea to link pi (3.14159…), which begins with 3.14, with the date 3/14 or march 14. co-workers built on the idea and they had a mini-celebration with just the staff, starting with eating of pies. the next year, the holiday was held for all at the museum and every year since, even when the museum was closed during its move. the celebration includes a parade at 1:59 p.m. with visitors holding a sign with a digit of pi, a pi shrine, eating of pies (fruit and pizza), singing happy birthday to albert einstein, and more. larry shaw would lead the parade in his red cap with the digits of pi. pi day was recognized as a national holiday in 2009 and is internationally celebrated. also, 2015 was a special year with it being written 3/14/15, calling it "pi day of the century". shaw felt the best thing about pi day was making math more accessible, fun for those who may have had problems in school. when asked if he was proud with events being held around the world, "yes and no. it's not mine; it's everybody's. i'm just the guy holding the pole."
