Pi Day 2014

Once again, Pi Day has arrived!

As you probably know, pi (π) is a mathematical constant found in circles and throughout mathematics! Since pi’s decimal expansion starts off 3.14…, and today’s date is 3/14, we celebrate pi and all things mathematical on this day!

My Top Pi Ways to Celebrate Pi Day

1. Share pi (and pie) with friends
2. Read and learn more about pi
3. Contemplate the wonder of the universe and mathematics’ role within it
.14159…. Shout “Happy Pi Day!” and/or “Happy Pi Moment” at the top of your lungs when the appropriate time occurs

Pieces of Pi

Related to #1 and #2 above, here are a few cool tidbits about pi and pi day:

Pi Past

I cannot believe it’s been 10 years since my first pi day expansive email that set up (or continued) a crazy propaganda war between the mathematical constants pi and e. (Going back even further, by my count I’ve been celebrating pi day in some form or another for almost 18 years now!) Just about each year since 2004 I have sent out my annual missive on Pi Day, by email and/or by blog (a few years when March was especially busy for me, I sent out messages on other pi-related days). A list can be found in yesterday’s pre-pi-day post here.

Have a great Pi Day today, and many more!

Nick
