From Symmetries to Strings : Forty Years of Rochester Conferences, Rochester, New York, 4-5 May 1990 : a symposium to honor Susumu Okubo in his 60th year

This conference celebrates the 40th anniversary of the first Rochester Conference and honours Prof. Susumu Okubo on his 60th birthday. The original Rochester Conference brought a small group of leading physicists to discuss current results and trends in both theory and experiment. The present conference has also adhered to this format — covering the developments in particle physics over the last forty years and presenting the latest theoretical and experimental results in the field.
