Mark D. Semon

Professor of Physics




Ph.D. University of Colorado, 1976; A. B. Colgate University, 1971

I’ve been the author or co-author on papers about quantum scattering theory, momentum and energy in the electromagnetic field, a new formulation of quantum electrodynamics, a new model for velocities in special relativity, a new equation of state for a liquid-gas system near a critical point, and the interaction in the Aharonov Bohm effect. I also work with attorneys estimating the speeds of vehicles involved in fatal accidents. My hobbies include playing the banjo and guitar, farming in Montana, and restoring old pickup trucks.
