No pi means no pie for you, buddy

Apparently some people think that pi is a flawed mathematical measurement. Not being much of a math person, I wouldn't know, although I definitely remember playing around with unit circles and radians in several math courses throughout high school and college.

And I've never heard of tau, which these pi-haters say is the better number to use. It's twice the amount of pi.

Yeah. I don't have anything more intelligent to add. Article!
