# It’s Pi Day – do some math!

Today is 3.14 — shorthand for the mathematical constant π (aka pi), which you may remember as the ratio of a circle’s circumference to its diameter. In college, friends could recite pi out to umpteen decimal places; I’m happy with 2.

I didn’t realize until last year that the date has other mathematical significance: Albert Einstein was born on Pi Day (yay!) and astrophysicist Stephen Hawking died on this day last year (sad).

The US Department of Education has some nifty ways to celebrate the day, including writing a Pi-ku. A haiku follows the pattern of 5-7-5 syllables in each line; a Pi-ku uses (yup) 3-1-4 syllables. My attempt:

Show a kid

Math can be fun!

Now you try it. Post in the comments, but keep it G-rated, please. The Pi Day organization also has suggestions, here. The title image is their Pi Day bunting, in case you want to make some of your own.

So calculate or recite π, help a kid with a math problem or talk to them about your work in science and engineering, read something by the amazing Stephen Hawking or eat a wedge of your favorite pie. Many pizza chains are also offering deals, which you can read about here.

Delicious and educational, all at once.
