Today, March 14, or 3/14, is National Pi Day! For mathematicians and engineers, Pi Day celebrates Pi, the symbol used to represent a constant in mathematics – the ratio of a circumference of a circle to its diameter.

Pi Day was founded by physicist Larry Shaw in 2001 at the Exploratorium in San Francisco, CA. It became official in 2008 when the US House of Representatives passed Resolution 224 naming March 14, 2009 Pi Day. Today, Pi Day is celebrated around the world in schools, universities and communities with pie eating and baking contests, 5k events and more activities - even parades!

Here are some fun facts for Pi Day:

  • Pi has been calculated to over one trillion digits beyond its decimal point!
  • Pi is an irrational number, and continues forever! It is infinite and patternless.
  • The Greek letter “π” was first used by William Jones in 1706.
  • Pi Day is also Albert Einstein’s birthday.
