Back in the days of school I was not a fan of mathematics. It was always my worst subject, the bane of my homework existence. Algebra and calculus? Why would I ever need to know any of that crap? Of course, as I got older and wiser I began to see the usefulness of math in my everyday life. When I began jacking beats and constructing little songs in the late '90s it became apparent to me how mathematical music is - I mean, it's all about numbers. As a result I have a bit more respect for math, although if I had homework I'd probably still be hating on it.
Pi is also a great movie by Darren Aronofsky that is all about math and how it is everywhere in life. Just don't let it drive you to drill a hole in your head, OK?
Here are a few of my favorite numerical numbers...
