It is the facts that matter, not the proofs. Physics can progress without the proofs, but we can't go on without the facts ... if the facts are right, then the proofs are a matter of playing around with the algebra correctly.
Richard P. FeynmanIt's because somebody knows something about it that we can't talk about physics. It's the things that nobody knows anything about we can discuss.
Richard P. FeynmanA poet once said, "The whole universe is in a glass of wine." We will probably never know in what sense he meant that, for poets do not write to be understood. But it is true that if we look at a glass of wine closely enough we see the entire universe.
