We are trying to prove ourselves wrong as quickly as possible, because only in that way can we find progress.
Richard P. FeynmanThe electron is a theory. But the theory is so good we can almost consider them real.

Richard P. FeynmanYou say you are a nameless man. You are not to your wife and to your child. You will not long remain so to your immediate colleagues if you can answer their simple questions when they come into your office. You are not nameless to me. Do not remain nameless to yourself — it is too sad a way to be. Know your place in the world and evaluate yourself fairly, not in terms of the naïve ideals of your own youth, nor in terms of what you erroneously imagine your teacher's ideals are.
