3.14 Ways to Celebrate National Pi Day

While Thursday will herald St. Patrick's Day celebrations with verdant inebriation, and on Tuesday, fans of Caesar will beware the Ides of March, today is a special day reserved for math geeks to relish in the glory of pi.

National Pi Day occurs yearly on March 14, aka "3.14," the first three digits of pi, which is equal to the ratio of the circumference of a circle to its diameter. (Tickled and want to know more? No need to dust off your high school geometry books, piday.org provides many resources for the mathematically curious.)

In honor of the enigmatic number, which never ends and never repeats, pie-related events are scheduled for the day, including an apple pie giveaway sponsored by Raytheon. The defense contractor will hand out pies to all the schools within a 3.14-mile radius of its headquarters in Waltham, Mass.

Pi also recently inspired musician Michael John Blake to put the number to music in a song called "What pi sounds like." (Pi apparently sounds like a new-agey children's song involving a banjo, a ukulele and some well-timed clapping.)



And, taking first prize for esoteric sports cheers, "E to the U," an MIT chant, manages to slip in the first six digits of the numerical constant without breaking the surprisingly clever rhyming scheme.

"I'm a Beaver, you're a Beaver, we are Beavers all.
And when we get together, we do the Beaver call.
E to the U du dx,
E to the X dx.
Cosine, secant, tangent, sine, 3.14159.
Integral radical mu dv
Slipstick, slide rule, MIT.
Go Tech!"

If you can explain the rest of the chant, then we'd like to wish you a very happy National Pi Day.
