# 3.14 is International Pi Day!

March 14, 2012

Today marks the mathematically quirky Pi Day, celebrated because the month and day of today’s date — 3/14 — correspond to the first three digits of pi: 3.14. Observed in science and math communities around the world, Pi Day has become an annual event that is recognized on universities campuses, in particular.

Where did Pi Day come from?

Larry Shaw created Pi Day in 1988. The holiday was celebrated at the San Francisco Exploratorium, where Shaw worked as a physicist, with staff and public marching around one of its circular spaces, then consuming fruit pies. The Exploratorium continues to hold Pi Day celebrations.

What a day! Thank you Larry Shaw, the Prince of Pi!

Is he giving us the finger? Never mind…let’s celebrate Pi Day!

Q: What did the the bad mathematician say?

That’s because he was a…

1. Sorry guys, but technically it’s International Pi-Rounded-to-the-Nearest-Hundredth Day!

• …but this is still brilliant, Thom.

• Thom says:

You are correct, Michael. But we couldn’t fit that in the title…

Thank you!

Pi Day is my favorite holiday, and not just because it happens to fall on the birthday of Albert Einstein, my birthday buddy.

• Thom says:

Well, then an especially Happy Pi Day to you, Jen. May its circumference be huge for you…

• Thom says:

And not too squared…

New College (now Harvard University) started out in 1636 with nine students and one instructor.
