"When we say two bodies 'touch', what we mean (without knowing it) is that both electromagnetic fields are interacting to avoid physical interpenetration and ... that happens well before subatomic particles touch!"

"There is no problem more difficult to solve than that created by ourselves."

"The only thing that interests the physicist is finding out on what assumptions a framework of things can be constructed which will enable us to know how to use them mechanically. Physics, as I have said on another occasion, is the technique of techniques and the ars combinatoria for fabricating machines. It is a knowledge which has scarcely anything to do with comprehension."

"Energy is liberated matter, matter is energy waiting to happen."

"What I am going to tell you about is what we teach our physics students in the third or fourth year of graduate school... It is my task to convince you not to turn away because you don't understand it. You see my physics students don't understand it... That is because I don't understand it. Nobody does."

"Not only is the Universe stranger than we think, it is stranger than we can think."

"In the beginning there was nothing, which exploded."

"Define the word exist, and you'll know whether God exists."

"I remember discussions with Bohr which went through many hours till very late at night and ended almost in despair; and when at the end of the discussion I went alone for a walk in the neighbouring park I repeated to myself again and again the question: Can nature possibly be so absurd as it seemed to us in these atomic experiments?"

"Sometimes I wonder if my heart is like a black hole--it's so dense that there's no room for light, but that doesn't mean it can't still suck me in."

"Something deeply hidden had to be behind things."

"Much later, when I discussed the problem with Einstein, he remarked that the introduction of the cosmological term was the biggest blunder he ever made in his life. But this 'blunder,' rejected by Einstein, is still sometimes used by cosmologists even today, and the cosmological constant denoted by the Greek letter Λ rears its ugly head again and again and again."

"Consciousness cannot be accounted for in physical terms. For consciousness is absolutely fundamental. It cannot be accounted for in terms of anything else."

"Maybe knowledge is as fundamental, or even more fundamental than [material] reality."

"Nonsense is that which does not fit into the prearranged patterns which we have superimposed on reality...Nonsense is nonsense only when we have not yet found that point of view from which it makes sense."

"The important thing is to not stop questioning. Curiosity has its own reason for existence. One cannot help but be in awe when he contemplates the mysteries of eternity, of life, of the marvelous structure of reality. It is enough if one tries merely to comprehend a little of this mystery each day.—"Old Man's Advice to Youth: 'Never Lose a Holy Curiosity.'"LIFE Magazine (2 May 1955) p. 64"

"The people who actually make the advances in theoretical physics don't think in these categories that the philosophers and the historians of science subsequently invent for them"

"Photons have mass? I didn’t even know they were Catholic."

"Order is heaven's first law."

"The very nature of the quantum theory ... forces us to regard the space-time coordination and the claim of causality, the union of which characterizes the classical theories, as complementary but exclusive features of the description, symbolizing the idealization of observation and description, respectively."
