Research is not a systematic occupation but an intuitive artistic vocation.

Research is four things: brains with which to think, eyes with which to see, machines with which to measure and, fourth, money.

A substance that makes you ill if you don't eat it.

A discovery must be, by definition, at variance with existing knowledge. During my lifetime, I made two. Both were rejected offhand by the popes of the field. Had I predicted these discoveries in my applications, and had those authorities been my judges, it is evident what their decisions would have been.

If any student comes to me and says he wants to be useful to mankind and go into research to alleviate human suffering, I advise him to go into charity instead. Research wants real egotists who seek their own pleasure and satisfaction, but find it in solving the puzzles of nature.

Nature is one. It is not divided into physics, chemistry, quantum mechanics.
