Over the past few years we've seen remarkable, as we will as at times independent advances in the understanding of extended objects like strings, black holes as we will as membranes at the ‘microscopic’ level. This volume primarily focuses on the synthesis of many diverse ideas in the physics of extended objects. The topics discussed include black holes as solutions of superstrings, string-membrane duality, QCD as we will as strings, as we will as nonperturbative strings
