Lectures
Complex Methods
 Part IB Course on Complex Methods. Lecture notes in PDF format.
Quantum Gravity
 These are the overheads for a lecture given in Oxford in 1995 entitled "How the Complex Numbers Got into Physics" at a meeting on "Complex Numbers in Quantum Mechanics". In PDF format
Special Relativity
 Part I Lecture Notes on Special Relativity in PDF format. This is a much extended version of notes
covering the material of the now defunct Part IB course. They should be useful as preliminary reading for the Part II courses on General Relativity and Relativistic Electrodynamics and Cosmology, and also for the Part III courses on General Relativity and Black Holes and Cosmology.

Statistical Physics and Cosmology
 Lecture Notes on Statistical Physics and Cosmology. This is a set of lecture notes for the Part II course 'Statistical Physics and Cosmology' which I gave a few years ago. I am grateful to Tim Perkins for transcribing them from handwritten notes and making the figures.
 An Atlas of the Universe
Black Holes
 Lecture Notes on Black Holes. These notes were prepared by Prof Townsend for the Part III course of this name which he gave. They are based on my own handwritten notes for a version of the same course that I had given earlier.

 The man who invented black holes
 These lectures, given in Paris some years ago, cover the basic thermodynamics of black holes at the level of the Part III course.
 The First Law of Thermodynamics for Rotating Black Holes in AntideSitter Space (lecture given at Indian Strings Meeting 2004, Khajuraho, December 1523 ).
