Several of the early chapters are on the topic of general field theory, but explained from a new point of view resulting from insights gained from string field theory. A standard course on quantum field theory is assumed as a prerequisite.

These notes give an introduction to string theory for students and interested researches. No previous knowledge of string theory is assumed. The focus is on gravitational aspects and we explain how gravity is described in string theory.
