C.N. Yang, one of many maximum physicists of the twentieth Century, was once provided the Nobel Prize in 1957, together with T.D. Lee, for study referring to basic actual rules, excellent the area of physics by way of demonstrating that trouble-free debris and their reactions discriminate among their left- and right-handed states, a estate often called parity nonconservation. With R.L. generators, he created the concept that of non-abelian gauge theories, the basis of the fashionable description of simple debris and forces. Professor Yang has labored on quite a lot of topics in physics, yet his enduring matters were symmetry ideas and statistical mechanics. In 1999, a symposium used to be held on the country collage of latest York at Stony Brook to mark the retirement of C.N. Yang as Einstein Professor and Director of the Institute for Theoretical Physics, and to have fun his many achievements. A noteworthy choice of the papers provided on the symposium looks during this quantity in honor of Professor Yang.
