Bibliography


Geoff Stedman obtained his B.Sc. (hons) in Physics from the University of Canterbury in 1965. He went on to obtain his Ph.D in 1969 from the Department of Physics, Queen Mary College, London where he investigated ion-lattice interaction in rare earth salts. Since then he has held research and lecturing positions at Queen Mary College and the University of Canterbury respectivley.

Geoff Stedman holds an emeritus professorship of physics at the University of Canterbury. He has a background in theoretical physics but has been involved in the ring laser project since its inception. Geoff's other interests include symmetry in quantum mechanics and foundations of relativity.
