Neil Constable McGill University Much of the recent activity in the string theory community has focused on exploring the so called Maldacena Conjecture. The claim is that Supergravity (or String Theory) formulated on a particular spacetime known as Anti-deSitter space, is actually equivalent to a supersymmetric Yang Mills theory. While the conjecture is certainly of great interest in its own right it has been suggested that it is possible to use the equivalence to study "real world" gauge theories. In particular it seems that one can learn about ordinary, everyday QCD. The first part of the talk will be an attempt to introduce the main ideas and the motivation behind the Maldacena conjecture. The remainder of the talk will show how these ideas can be used to desribe QCD, as an example I will review recent work in which the mass spectrum of scalar glueballs has been calculated.
