Celebrate Pi Day!

The Ides of March are coming tomorrow, but today is Pi Day! The Greek letter π is the symbol for the ratio of the circumference to the diameter of a circle, equivalent to 3.1415926535...

We can't let the mathematicians have all the fun. Classicists love the number π because it's also a Greek consonant letter!

Pi day is celebrated every March 14, the fourteenth day of the third month, or 3/14.

To find out more about Pi Day, visit the Official Pi Day website, where you can find out all about the history of pi, discuss the number pi, send an e-card, buy pi stuff, get ideas for your own pi party, and much more! There are also some great lesson ideas at the Teach Pi website.

A lesser known, and less-often celebrated mathematical holiday is Square Root Day.
