Yes, these are fascinating.  As for "being good with this", well, the
theory is both highly technical and not especially glamorous, the only
ones good with it are those who need it.


I know from reading sci.physics which parts are glamorous.  Everybody and
his brother has a new Theory of Everything.  Revolutionizing our basic
conceptions of time, space, and matter are easy, and doesn't require any
math.  Unlike materials or optics or something.

Hey, that's a bit unfair on optics! Why, some optics is so simple that you don't need any maths at all, you just need to draw pictures! The really fun part is that this brand of optics (paraxial thin-lens ray optics) is all that most people ever need. Bizarrely, the useful part of optics is actually the easy part of optics.
