**Pi Day, it’s not just for math nerds.**

Pi Day is a day to celebrate the mathematical constant Pi (π). What is Pi? In this case we are not talking about a delicious dessert, no Pi is the name given to the ratio of the circumference of a circle divided by its diameter, approximately 3.14159.

The earliest known celebrations of Pi Day occurred in 1988 at San Francisco’s Exploratorium. Larry Shaw, a physicist at the museum, along with the public and staff celebrated the day by having a small, circular parade and then eating fruit pies. The museum continues to celebrate the day each year, and in 2009 March 14th was designated as National Pi Day by first session of the 111^{th} Congress of the United States.

Here are a few random tidbits to remember on March 14th.

- Albert Einstein’s birthday is on Pi Day, Einstein’s was born on March 14, 1879.
- The official observation begins at 1:59 (ideally at 26 secs).
- Pi has been calculated to 10 trillion decimal places.
- In 2015, Pi Day had special significance on 3/14/15 at 9:26:53 because the date and time represented the first 10 digits of π.
- Pi is represented by the lower case Greek letter – π – because it’s the first letter of the Greek work περίμετρος, meaning perimeter.
