Putting String Duality to Work

Abstract

This presentation is intended to give a flavour of the physics to be studied and discovered by exploiting the interface between string theory, M-theory and field theory provided by the dynamics of extended objects called `branes', and their relationships under string duality. It is quite non-technical, with very few equations but many pictorial illustrations to aid the reader. There is only a moderate amount of text, as the content is based upon transparencies which were intended to be accompanied by extra words. (Hyperlinked transparencies of a talk given at the annual UK Particle Theory Meeting,Rutherford Appleton Laboratories, Didcot, Oxfordshire, England, 15th December 1997.)
