I was just thinking about...

... the well-known formal equivalence between standard general relativity and its teleparallel reformulation. You know---whereas in standard general relativity the gravitational field comes about as the curvature of the Levi-Civita connection of a Lorentzian metric, in the teleparallel reformulation it comes about as the torsion of the Weitzenböck connection of a teleparallel tetrad field.

It's kinda funny when you think about it, isn't it?

She's reading the stuff she's copy editing again. Looks like MR has a dress code, too, now!

Ha! Nah, I'm voluntarily dressing up in Mathematician Chic to show my love for the place.

Aha! I like your pocket protector.

That darned physics!

Wow---I forgot there was somebody ought there who might actual FOLLOW that kind of thing.

er, OUT there

BTW, one day I'm gonna get it together at the office (where there's a decent connection) and listen to some of your uploaded songs. I'm looking forward to it.

Don't worry. I have a degree in physics, but I still don't follow the subtleties of relativistic theory. My understanding of modern physics peters out in the 1920's. Which partially explains why I'm not a working physicist.

Well, you may not be a working physicist, but you looked damned good with that rocket.

the image is chris makepeace, star of "Meatballs," from the 80s. My hair looks like his when I've gone too long w/o a haircut.

I prefer to think of the crazy-curly long hair of [livejournal.com profile] sprig5---see this here picture, even though it's not exactly what it looked like live, I don't think. (I recall the overall roundness of the thing being more symmetrical.) (Hey, maybe that's it---you know I get off of symmetry!)
