3/14/15 is National Pi Day!

National Pi Day

AUSTIN (KXAN) — 3/14/15 equals National Pi Day! The first five digits of Pi line up with today’s date.

Pi is the symbol used in geometry to represent the ratio of the circumference of a circle to the circle’s diameter. You can use it to find the area of a circle, which is Pi times the radius of the circle squared.

To celebrate the day, there are numerous events going on throughout the country.

At 9:26 a.m. (After 3.1415, the numbers are “926” hence the time), high school seniors will find out if they got accepted into MIT. Lovebirds can tie the knot in Vegas for $314.15 and they even get an apple pie. And at the holiday’s birth place in San Francisco, there will be a pizza pie tossing.

Dr. Michael Starbird, a mathematician at the University of Texas – Austin explains what Pi is.

“Pi is one of these numbers that has no pattern that repeats and so it just continues on forever. So, we’ll never know all of Pi, which I think is a metaphor for our understanding of the world: that we continue to learn more things,” said Starbird.
