Physics is an otherworld thing, it requires a taste for things unseen, even unheard of- a high degree of abstraction... These faculties die off somehow when you grow up... profound curiosity happens when children are young. I think physicists are the Peter Pans of the human race... Once you are sophisticated, you know too much- far too much. Pauli once said to me, "I know a great deal. I know too much. I am a quantum ancient.".

There are questions which illuminate, and there are those that destroy. I was always taught to ask the first kind.

Suddenly, there was an enormous flash of light, the brightest light I have ever seen or that I think anyone has ever seen. It blasted; it pounced; it bored its way into you. It was a vision which was seen with more than the eye. It was seen to last forever. You would wish it would stop; altogether it lasted about two seconds.

We must also teach science not as the bare body of fact, but more as human endeavor in its historic context-in the context of the effects of scientific thought on every kind of thought. We must teach it as an intellectual pursuit rather than as a body of tricks.

It was eerie. I saw myself in that machine. I never thought my work would come to this.

We gave you an atomic bomb, what do you want, mermaids ?

I think physicists are the Peter Pans of the human race. They never grow up and they keep their curiosity.
