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.

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

The real scientist is ready to bear privation and, if need be, starvation rather than let anyone dictate to him which direction his work must take.

[A vitamin is] a substance you get sick from if you don't eat it.

A discovery is said to be an accident meeting a prepared mind.

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