Tattoos For the Math and Science Geek?

An anonymous reader writes "I've been thinking of getting a sleeve of math and science tattoos for quite a while now. With the money saved up, the only question remaining is, what equations/ideas should I get? I know for certain that I'm going to include some of Maxwell's equations, and definitely Ohm's Law. So, if you were going to put a tribute to the great math and science minds on your body forever, which ones would you choose?"
