As you may already know, today is the best day of the year. Why? Because you get to revel in the glory that is math *and* you get to eat pie. That's right, Pi Day is upon us once again.

Pi Day occurs each year on March 14^{th} On this day, the date is written as 3.14. Ultimately, pi corresponds to this number (it is the mathematical constant that represents the ratio of a circle's circumference to its diameter, and is typically written 3.14159) . The number pi is actually represented by the Greek letter "π". But in the 18th century, it started being spelled at "pi" in popular usage.

According to the Pi Day website www.piday.org, “Pi has been calculated to over one trillion digits beyond its decimal point. As an irrational and transcendental number, it will continue infinitely without repetition or pattern. While only a handful of digits are needed for typical calculations, Pi’s infinite nature makes it a fun challenge to memorize, and to computationally calculate more and more digits.”

In November of 2004, a chemistry student from China, Chao Lu, attempted to recite as much of pi as possible. Lu practiced for over four years for the attempt and made it to an astounding 67,890 numbers. This feat earned Lu a place in the Guinness Book of World Records for the most places of pi memorized.

In honor of the day, we are going to give out a free pie to one lucky winner. To participate, simply send us your best pi joke. The comment with the most "likes" will win (subject to judges discretion). In the event that there are several astounding submissions, we may declare more than one winner. And of course, you get to choose your own pie. Head over to Grand Traverse Pie Company to see their flavors. Not a huge fan of pie? No worries, Grand Traverse ships a variety of items (brownies, cookies, cheesecake etc.). If you win, you can choose something else that is the same value.

Yes, yes. It is Pi Day, but the important thing is that you like *pi*; you don't have to actually like *pie*.

Don't live in the United States? No worries, most countries have bakeries that ship pie. If you win, we will find a store that ships to you or come up with an alternate prize. To enter, simply head over to our facebook page and comment on the Pi Day post. The winner will be announced this evening.

Please note, we will need your address in order to ship you the pie. To learn about our privacy policy, please see our privacy page.
