I don't throw around the words "pure genius" very often. Well... maybe I do but this time it is truly appropriate.
Check out this video. The Electric Company meets The Knights Templar equating maths with paganism. Really. I'm not making this shit up.
You must look at it now!
That video has left me, for once, entirely without words. What the?
If pi interests you, though, I recommend reading The History of Pi. The author prefaces the book by touting himself as especially qualified to write it because he is neither a mathematician nor a historian. Pi, a vexingly irregular number, serves as a sort of litmus test for societies’ sophistication. The book tours various efforts throughout history to measure, calculate, legislate, and decree its value.
