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?

I prefer to think of the crazy-curly long hair of 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!)
