Research Interests:
I am interested in the mathematical and philosophical foundations of modern physics. I have done some work on classical equilibrium statistical mechanics [6] and quantum mechanics [14, 17]. (The numbers refer to papers listed in my curriculum vitae.) But most of my work has dealt with problems of spacetime structure and the foundations of relativity theory. Topics have included: (i) the “causal structure” of spacetime [4, 5]; (ii) the relation of relativity theory to Newtonian gravitation theory [10, 11, 16]; (iii) Gödel’s model of spacetime structure [8, 12, 14, 15, 18]; and (iv) rotation in relativity theory [9, 18, 19].
