Nature is one. It is not divided into physics, chemistry, quantum mechanics.

I always tried to live up to Leo Szilard's commandment, "don't lie if you don't have to." I had to. I filled up pages with words and plans I knew I would not follow. When I go home from my laboratory in the late afternoon, I often do not know what I am going to do the next day. I expect to think that up during the night. How could I tell them what I would do a year hence?
