Happy Pi Day! March 14 is a day that's celebrated both by math lovers and those who enjoy tasty slices of pie. It's a day to honor the ratio of a circle's circumference to its diameter, which is 3.14159265359 (and so on to infinity) and often rounded to 3.14.

Pi Day took off in 1988 when physicist Larry Shaw celebrated the symbol at the San Francisco Exploratorium, where he worked. Shaw and the staff reportedly “marched around a circular space" and then enjoyed some fruit pies afterwards. The U.S. House of Representatives recognized March 14 as National Pi Day in 2009.
