The attempt to understand the nature of particle physics at the weak scale is the major goal of the current generation of collider facilities. Theorists attempt to stretch their theories to the Planck scale and beyond with the very ambitious theory of superstrings. Particle physics at all energy scales has important implications for the theory of the Early Universe. Lectures on Standard Model, Grand Unification and Supersymmetry and the present status of string and superstring theory are given by both theorists and experimentalists in a complete and pedagogical manner. Finally, lectures notes on the Early Universe, galaxy formation, and high energy colliders are directed specifically at particle physicists.

The Proceedings of the Workshop covers a broad range of subjects from low energy supersymmetry through supersymmetric grand unification to supergravity and superstring theories. Although the focus was mainly on theoretical problems and ideas, the present and future experimental searches of new particles were also discussed.

Although gravity is the dominant force of nature at large distances (from intermediate scales to the Hubble length), it is the weakest of forces in particle physics, though it is believed to become important again at very short scales (the Planck length). The conditions created in particle accelerators are similar to those at the time of the early
