Today is pi day! So says piday.org, founded by Dan Hellerich back in 2001, for the simple reason that 3/14 is the closest anyone’s going to get to 3.14159265.
The point of pi day? To celebrate pi, of course. That means reading about pi-related mathematical strangenesses, buying pi-related merchandise, and of course, eating pie.
Or in the words of Bill Amend on Twitter: “Pi Day: a day for people of the world to put aside their differences, join hands in a big circle and then calculate the circumference.” To at least 10 decimal places, Bill.
And if, after all that, you still need convincing that we should celebrate pi’s existence, consider this mathematical wonder: 1337 (the number of the ‘leet) multiplied by pi equals: 42 (the answer to Life, the Universe and Everything). QED.
