3/14/15 is Pi-est of Pi Days!

by Fiona Shields
Every March 14, we celebrate the day where mathematics and round food intersect -- π (Pi) Day! Pi, the ratio of a circle's circumference to its diameter, has drawn many admirers for its infinite, non-repeating digits as an irrational and transcendental number. It's been calculated to the ten trillionth digit, and math enthusiasts and students all around the world challenge themselves to memorize pi 100 (or 67890) places past the decimal point!

Since pi begins with 3.14159, it only makes sense that March 14 (3/14) has been nationally recognized as Pi Day. This year has special significance as it will occur on 3/14/15, or the first six digits of pi!

This mathematical constant also has the happy coincidence of having a homophone that's one of our favorite round baked goods -- pie. This is how we like to observe Pi Day (and also Alfred Einstein's birthday), but we encourage you to eat or enjoy anything circular in shape!

To celebrate Pi Day to the pi-est, have a slice of pie on 3/14/15 at 9:26 am/pm and check out one of our materials related to pi, pie, or mathematics:
