Guess what today is! If you said “Steak and a Blowjob Day,” then I guess you’re technically correct, but March 14 is also Pi Day—an occasion on which the date (in American notation) corresponds to the first three digits of the mathematical constant π. This year’s festivities are especially significant, as “3/14/15” extends the numerical sequence even further.
I'm keeping track of all the math nerds who tweet about Pi day so I can steal their lunch money on Monday— Eric Tanoye (@toyns) March 14, 2015
Over on Reddit, meanwhile, mathematicians and historians teamed up to answer every question you have—and many you’d never considered—about the irrational ratio. For instance, did you know that in 1916, a Norwegian man, Andreas Dahl Uthaug, self-published a book called Norwegian Mathematics: The Mathematics of the Future, in which he argued that pi should be defined as 3.125 exactly? Can’t believe folks didn’t go for that.
Personally, I’ll be observing the momentous calendar event by staring at this trippy website, Thank God It’s Pi Day, for several hours. And biding my time until this Pi Day 2015 T-shirt goes on sale at midnight. And, what the heck, maybe calculating the area of some circles.
