I am a Senior Research Fellow at Trinity College, University of Cambridge. My main research interests are philosophical aspects of quantum theory, relativity theory and classical mechanics.

Most of my papers from recent years can be found at the ‘Los Alamos archive‘ (look under ‘physics’, ‘quant-ph’ and ‘gr-qc’), or at the ‘Pittsburgh Philosophy of Science archive‘. A list of publications is here.

For links and more resources, go to: the Cambridge Quantum Information website, and the Oxford Philosophy of Physics website.

Some Recent Lecture Courses

The Leibniz-Clarke Correspondence

The first part of this course (given in 2000), Part A, introduces the philosophy of geometry and motion. The second part, Part B, first gives a potted history of conceptions of space prior to the Correspondence; and then discusses two recent interpretations of Newton’s and Leibniz’s rival conceptions of space: namely, the interpretations of Julian Barbour and Robert Rynasiewicz. (NB: For both parts of the course, the diagrams are missing: one day I’ll do it …)

The Philosophy of Thermal Physics

This course (given in 2000), available here, discusses the philosophical aspects of: first thermodynamics, and then statistical mechanics. The reading list is a separate file. (Again: the diagrams are missing: one day …)
