4 "funny" facts to celebrate National Pi Dayby GoComics
If you haven't thought about pi (the Greek letter, not the dessert) since high school, we don't blame you. If, on the other hand, you think about pie (the dessert, not the Greek letter) constantly, we don't blame you for that, either.
For those of you who fall into the first category, here's a refresher: Pi represents the ratio of a circle's circumference to its diameter. Although its true numerical value is infinite and patternless, pi is usually rounded to 3.14. That's why every year on March 14 (3/14), we celebrate National Pi Day!
Although the most common celebration involves - you guessed it - eating pie, some may say there are infinite ways to honor this mathematical wonder.
For our part, we're sharing four of our favorite pi facts:
1. In 2009, the United States government endorsed Pi Day as an "engaging way to teach children about geometry."
2. Pi has been calculated to more than one trillion digits past its decimal point, although only 39 are needed to calculate the volume of the universe.
3. Since there is no pattern, some people challenge themselves to memorize as many digits as they can.
4. Last year on Pi Day, at 9:26:53 a.m., the first 10 digits of pi were represented (3/14/15, 9:26:53). It was the ultimate Pi Day.
