![]() Pi Day HistoryPi Day celebrates the mathematical constant π (pi), 3.141592653... Pi is the ratio of a circle's circumference to its diameter. The circumference of a circle is defined as its arc length while the diameter is defined as the longest chord of the circle. Pi is a special number due to its infinite and pattern-less nature. This means that the digits after the decimal point never repeat themselves in a specific pattern. Pi Day was established in 1988 by Physicist Larry Shaw. Shaw was an employee at the San Francisco Exploratorium where the first Pi Day was held. It took place on March 14th (3/14), given that the first digits of Pi are 3.14. On March 12, 2009, the U.S House of Representatives recognized March 14 as National Pi Day. Top Tweets for Pi Day -
