Math geeks of the world rejoice, because March 14 is the day we celebrate pi, as in 3/14, get it?
Of course none of this makes any sense if you live in a part of the world where everyone writes the date the sensible way around, with the day first and the month after, but that won't stop us. Sadly, for those sensible countries there are only 30 days in April, so it doesn't work if you write the date their way.
So how do you plan to celebrate? You could eat a pie, you could recite pi to as many places as you can like the kid in our video, or you could just watch Life of Pi. Of course if you're going to do that make sure you eat potato chips instead of popcorn, because today also happens to be National Potato Chip Day.
