Well, let me know what you find out if you have the time. I can read all I want in this area, but in physics- if it goes beyond just basic reasoning and logical evaluation, I'm pretty much lost. A hawk is as good a s a handsaw. I always fantasize that if I retire someday I'll pick up a few other degees. Physics and Chemistry are two areas I'd like to know more about.
