Whatever a man does he must do first in his mind.

Investigations during the last few decades have brought hydrogen instead of carbon, and instead of CO2 water, the mother of all life, into the foreground.

Research is to see what everybody else has seen, and to think what nobody else has thought.

Without energy life would be extinguished instantaneously, and the cellular fabric would collapse.

Life is a wondrous phenomenon.

I always tried to live up to Leo Szilard's commandment, "don't lie if you don't have to." I had to. I filled up pages with words and plans I knew I would not follow. When I go home from my laboratory in the late afternoon, I often do not know what I am going to do the next day. I expect to think that up during the night. How could I tell them what I would do a year hence?

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