This text contains a selection of contributions by scientists who have worked with Sergio Fubini, and offers a panorama of recent and interesting achievements in experimental and theoretical particle physics, gauge and string theories and related topics. It also contains some reports about the historical development of this branch of activity, with its political, financial and cultural implications for the present and future. The common feature of the contributions is the search for symmetry and simplicity in complex phenomena. The book represents a struggle toward the future without forgetting the good and the bad points of the past.
