String theory "classical" limit? I know nothing about string theory, I'm still trying to deal with the more basic early 20th century stuff. But a question popped into my head which I hope someone can answer or point me to an answer. In general relativity you can recover Newtonian gravitational physics by applying the field equations to a slowly varying, weak gravitational field. In Maxwell's electrodynamics you can recover Coulomb's electrostatics law (I forget exactly how). In special relativity you can recover Newtonian mechanics in the limit as velocities go to zero. Can you do the same with string theory? Can you recover general relativity from string theory in some limit? What about quantum mechanics and quantum electrodynamics?
