From Symmetries To Strings: Forty Years Of Rochester Conferences [PDF ebook] 

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.
