I knew all the time I was going to get through the war. It was completely irrational, a silly idea, but I was not going to lie down and get myself killed. I was going to get out of it.

Weak, electromagnetic, and strong interactions have distinct intrinsic symmetry properties, but this hierarchy of symmetries is not well understood theoretically. Perhaps the most puzzling are the small effects of noninvariance under space reflection and the even smaller effects of noninvariance under space reflection and the even smaller effects of noninvariance under time reversal. It adds to the puzzlement that the latter phenomenon has been observed so far only in a single instance, namely, in the K° - K^-^ system. (These phenomena were first observed after Einstein's death. I have often wondered what might have been his reactions to these discoveries, given his 'conviction' that pure mathematical construction enables us to discover tbe concepts and the laws connectin them'.
