Introduction to Superstring Theory - In these lecture notes, an introduction to superstring theory is presented. Classical strings, covariant and light-cone quantization, supersymmetric strings, anomaly cancelation, compactification, T-duality, supersymmetry breaking, and threshold corrections to low-energy couplings are discussed. A brief introduction to non-perturbative duality symmetries is also included.

Introduction to Non-Pertubative String Theory - In this review I discuss some basic aspects of non-perturbative string theory. The topics include test of duality symmetries based on the analysis of the low energy effective action and the spectrum of BPS states, relationship between different duality symmetries, an introduction to M- and F-theories, black hole entropy in string theory, and Matrix theory.

M-Theory - The theory formerly known as strings is presented in a non-technical format

An Invisible Dimension - Extra spatial dimensions--beyond the three we know--might exist, while being invisible to most experiments.
