Einsteimania is no solely the fault of herr doktor-proffesor E. -- see the book on fractals and power-laws e.g.
anyway, do you see that teh angular momentum of atoms, at least, explains inertia, relativistically?

thus: the Grace datum clearly shows that thoswe two icesheets are still rising, but it can't be by very much; they have always been stacked to the gills.

thus: GR is no more of a theory about the curvature of space, which is clearly manifest to geometers (viz, Eratosthenes and Gauss), than it explains what causes gravity, the same as Fig Newton.
however, it is simplicity, itself, to adduce the curvature of space from Newton's "decategorified" equation of "universal gravity." (obviously, Kepler did all of the legwork .-)
thus: the sole determinant of the speed (not velocity) of light, is the index of refraction of the medium, viz Snell's law.
the classsical problem was Liebniz's *brachistochrone*, although one has to realize that the ray-tracing idealization is not a natter of importance; just of interpretation ... and thr same applies to Minkowskian ligthconeheads, like Feynman.
thus: read the original write-up of the "two-pihole experiment" by Young, which totally exposed Newton's untheory of "corpuscles" of light, a 100 years after he screwed-up Snell's law -- just like Descartes, did.
thus: my main concern, for using diadians (or tau) is that the simplicity of (viz) radar distances is obscured; also, how to avoid confusion with radians (or "pi+pi"), since pi is generally considered to be a dimensionless constant, by some argument or other.
