The author is a retired professor of both physics and electrical engineering. After receiving his Ph.D. from Stanford in physics, he taught electromagnetic fields and elementary labs at George Mason University, in Fairfax, Virginia for 30 years. He was one of the originators of thermoacoustics (engines and refrigerators using acoustics instead of pistons) and has done research in superconducting microwave resonators, electron beam microwave amplifiers, worked with a startup company Microwave Technology, Inc, and worked on the roots of quantum mechanics. He has long felt that computer animation could aid in the teaching of waves and fields.
