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'.

he described his own ideals, the desire for fulfillment not just as a theorist but also as an experimental physicist. (In the second respect, he, of course, never matched Newton.)

Promising steps have been made toward grand unification, the union of weak, electromagnetic, and strong interactions in one compact, non-Abelian gauge group. In most grand unifies theories the proton is unstable. News about the proton's fate is eagerly awaited at this time. Superunification, the union of all four forces, is the major goal. Some believe that it is near and that supergravity will provide the answer. Others are not so sure.
