Math lovers celebrate today (3/14) as Pi Day, in honor of the irrational number pi.

Pi, or ?, is defined as the ratio of the circumference of a circle to its diameter. Pi is an irrational number, meaning it cannot be written as a simple fraction. Instead, it can be expressed as an infinite, nonrepeating decimal (3.14159…) or approximated as the fraction 22/7.

Here are some nerdy facts about the irrational number, to impress your friends as you celebrate Pi Day (which is also Albert Einstein's birthday).

Pi or pie? With today (March 14) being celebrated around the nation as Pi Day, these homophones can be confusing, especially when baking pies is a popular way to celebrate the famous mathematical constant.

A Texas Tech University alumnus decided to combine these words and create something for everyone to enjoy on Pi Day: a Pi Pie Pan, a pan in the shape of the pi symbol designed for baking pies.

“It’s a fun way for people to show off being a little geeky while enjoying to cook,” said Garrett Heath, creator of the pan. “There’s no better way to make a pie on Pi Day than to have a pi-shaped pan.”

I can't have just one slice of pie--or Pi Day, for that matter.
