In these lectures we review the quantum physics of large Schwarzschild black
holes. Hawking's information paradox, the theory of the stretched horizon and
the principle of black hole complementarity are covered. We then discuss how
the ideas of black hole complementarity may be realized in string theory.
Finally, arguments are given that the world may be a hologram. Lectures
