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.”.
