There is a reward structure in science that is very interesting: Our highest honors go to those who disprove the findings of the most revered among us. So Einstein is revered not just because he made so many fundamental contributions to science, but because he found an imperfection in the fundamental contribution of Isaac Newton.

Physics is an otherworld thing, it requires a taste for things unseen, even unheard of- a high degree of abstraction...
