Happy Pi Day! Pi, of course, is the Greek letter Л, the symbol for the ratio of the circumference of a circle to its diameter and is an infinite number beginning with the digits 3.14.
Today is 3/14, so we celebrate Pi Day! Larry Shaw created Pi Day in 1988 and it was approved by the US House of Representatives in 2009.
Princeton, NJ, hosts an annual celebration today to commemorate the birthday of one of its most famous citizens – Albert Einstein. Einstein lived in Princeton while working at the Institute for Advanced Study. Princeton hosts events such as pie eating, pi recitation contests, and an Einstein look alike contest.
