David J. Gross

Open full text 5 citations

Abstract

The evolution and present understanding of Quantum Field Theory are reviewed. The profound lessons of Quantum Field Theory are discussed. The attempt to go beyond Quantum Field Theory and construct a unified theory of particles, forces and quantum gravity is described; with emphasis on the achievements, problems and promises of string theory.
