Squashed,

Thanks for respecting my privacy. I first started with online BBS on CompuServe. That used to be pretty good years ago, but it's gone now -- AOL bought it and it went downhill fast. I quit it several years ago. Anyway, on the old Compuserve fora, the standard rule was one had to use your real name, no "handles" or screen names and that sort of stuff. The idea was real names discouraged bad behavior. But that was before everyone and his brother had internet access. I never liked Web based fora at first, but that's the way it's gone, and I found this one here, which I like pretty darn well.

Anyway, the math I used above is nothing more than some simple calculus plus algebra. Nothing to brag about at all, and when I do it, it makes me mad because I remember how much I've forgotten. "I used to be good", as the saying goes.

The math of General Relativity is some of the most advanced, and it's generally only at the graduate level does one tackle it. I never went that far. Several times I've said I was going to learn it, so I could sastify my curiousity about this kind of stuff, but well, this old dog doesn't learn new tricks too well.
