There seems to be a strong correlation between physicists and good computer scientists:- Knuth, Dijkstra for example.
Seymore Cray worked with radios during WWII and had a very strong background in electrical engineering. He had to rely on Maxwell's equations to analyse signal paths [0]. The bottom anecdote [1] I found highly amusing, very "egg and chicken".
