In this article we discuss some aspects of superstring theory. After a short introduction of string theory as unifying quantum theory of all interactions, we introduce the socalled brane world models. These models describe the universe as 3- or higher dimensional brane, embedded into the 9-dimensional space of string theory. They offer many interesting possibilities to derive the standard models of particle physics from string theory. In addition we discuss the AdS/CPT correspondence and some generalizations which are interesting, since they allow for a computation of non-perturbative effects in gauge theory, like chiral symmetry breaking, from a dual gravitational theory.
