I just read most of your story on this website(I stopped when you started discussing the details of your dissertation). (Interesting stuff) Did you ever consider using you physics knowledge for many of the gaming and graphic applications? The physics properties of light is very useful in rendering, real physics in games is of course monumentally useful, and cloth simulations, fluid simulations, there are so many practical applications of physics needed in the game development field. Why teach physics when you can apply it to games?
