March 14: Pi Day

March 14 — 3.14 — is Pi Day! It’s time to celebrate that irrational mathematical concept with math games, circles, and (my personal favorite) pies!

(Yes, I know it’s “pi” not “pie,” but pies are circular too! If it makes you feel better, you can measure the diameter and figure out the circumference and area before you eat it. 🙂 )

The verse today is a bit of a stretch, but bear with me. The earth rotating is similar to making a circle, right? And it just keeps going and going, like the digits of pi!

The sun rises and the sun sets,
and hurries back to where it rises.
The wind blows to the south
and turns to the north;
round and round it goes,
ever returning on its course.

Ecclesiastes 1:5 & 6

Just to make today even more exciting, the legendary scientist Albert Einstein was born on this day in 1879.

You can find more information, pictures, pi day clothing, and party suggestions at and at Pi Day at the San Francisco Exploratorium.

Happy Pi Day!
