Welcome to the math humor world! Pi Day on March 14th (3/14) annually, which is the ratio of the circumference of a circle to its diameter. The concept of Pi Day was initially introduced by physicist Larry Shaw in 1988 at the Exploratorium in San Francisco, in which they marched in circles and consumed pies—because, naturally, what is a greater way to commemorate Pi than with pie?
Pi Day celebrates the mathematical constant π (pi), which is the ratio of a circle’s circumference to its diameter. Physicist Larry Shaw first suggested the concept of Pi Day in 1988 at the Exploratorium in San Francisco, where they commemorated the day by marching in circles and consuming pies—because what is a better way to celebrate Pi than with pie?
In 2009, Pi Day was officially recognized in the U.S. when the House of Representatives voted on a resolution to endorse its celebration. Ever since, Pi Day jokes, playful math challenges, and pie-eating contests have become a tradition in schools, colleges, and even offices.
