The problem of the physical vacuum is presented in the opening lecture by T.D. Lee and the effective string-theoretical approach to cosmological vacua by G. Veneziano. Effective theoretical approaches to light and heavy quark physics are presented by H. Leutwyler and M. Neubert. V.N. Gribov discusses the quark confinement and N. Seiberg the problem of finding the effective actions in supersymmetric theories. A detailed analysis confronting electroweak theory with the high precision experimental data is presented by D. Schildknecht. The great specialist in membrane theory, M. Duff, presents the latest results of the 11-dimensional approach, while the finite temperature effective theories are discussed by M. Shaposhnikov. The unification and the physics beyond the standard model constitute the content of the lectures by R. Barbieri and D. Nanopoulos. The experimental data from LEP and HERA are presented by M. Pohl and G. Wolf. N.F. Ramsey, the world specialist in the field, discusses how to explore the universe with atomic clocks. An elusive Z' is the subject of a specialized seminar by P. Frampton.
This volume contains the reports presented by a selected group of "new talents" on various topics in the field of subnuclear physics.
