What is pi

We celebrate March 14. But what about Golden Ration Day in early January, or Euler's number e Day on Feb. 7? A UMBC prof imagines the nerdy possibilities.

However, in the 17th century, novel methods of mathematical analysis in Europe offered improved ways of calculating π through infinite series. The Babylonians estimated π to be about 25/8 (3.125), while the Egyptians estimated it to be about 256/81 (roughly 3.16). 250 BCE) is credited with devising the first method to calculate π to any desired accuracy, given enough patience. Pi Day is often celebrated with activities such as π-themed baking contests, math quizzes, and π recitation competitions. And this is why Pi Day is celebrated worldwide. This tradition started on March 14th, 1988, when physicist Larry Shaw organized an event at the San Francisco Exploratorium to honor the famous number and mathematics in general.
