About Me

“First you guess, then you compute the consequences. Compare the consequences to experience. If it disagrees with experience, the guess is wrong. It doesn’t matter how beautiful your guess is, or how smart you are. Or what your name is, if it disagrees with experiment, it’s wrong. That’s all there is to it.”
-Richard Feynman
