On behalf of math geeks, science lovers, and purveyors of questionable “holidays” everywhere, I’d like to wish everyone a Happy Pi Day.

Pi Day is celebrated once a year, on March 14th, as the date aligns with the first few digits of Pi (3.14). Pi, of course, is everyone’s favorite mathematical constant as it is the ratio of a circle’s circumference to its diameter. Tons of mathematical formulas use Pi, and this translates into real-life scientific and engineering applications. The world would be a terrible place without pie Pi, indeed.

On that note, let’s look at some of the best Pi Day related stuff the Internet has to offer. First up is this amazing video shared today by the Official YouTube Google+ page. Check out what happens when you assign music to all the digits in Pi.

Pi has reportedly been mapped out to 10 trillion digits, but you can check out the first million at piday.org. Fun games you can play here include turning on your browser’s find feature and looking up certain number patterns within Pi. For instance, my birthday (5/28/86) appears very early on in Pi:

Remember, Pi day can also be turned in Pie day. Literally. Flip is around and see what you have…mind blown:

Twitter is pretty excited about the day:

Not everyone is happy about an annual Pi Day celebration (via reddit):

And Dwight’s not the only one. Just wait until June 28th, and you’ll see plenty of Pi Day haters speak out. That’s because 6/28 is also a celebrated mathematical holiday: Tau Day. Tau is 6.28, or, double Pi. Tau purists argue that Pi is an insignificant number, only half of the real significant number. They say that Tau should be the true celebrated circle constant, as it is the ratio of a circle’s circumference to its radius.

But Tau doesn’t have a delicious, flaky, succulent homophone.
