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

Science itself is badly in need of integration and unification. The tendency is more and more the other way ... Only the graduate student, poor beast of burden that he is, can be expected to know a little of each. As the number of physicists increases, each specialty becomes more self-sustaining and self-contained. Such Balkanization carries physics, and indeed, every science further away, from natural philosophy, which, intellectually, is the meaning and goal of science.

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.".

My mother made me a scientist without ever intending to. Every other Jewish mother in Brooklyn would ask her child after school, So? Did you learn anything today? But not my mother. Izzy, she would say, did you ask a good question today? That difference - asking good questions - made me become a scientist.

If you decide you don't have to get A's, you can learn an enormous amount in college.

It was eerie. I saw myself in that machine. I never thought my work would come to this. Upon seeing a distorted image of his face, reflected on the inside cylindrical surface of the bore while inside an MRI (magnetic-resonance-imaging) machine-a device made possible by his early physical researches on nuclear magnetic resonance (1938).

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