Wonderful scholarship, as always Richard.  And a very entertaining read.
 The Einstein Field Equations are comically complicated and utterly
unusable.  Their closed form is printed on T-shirts, painted on the
sides of academic buildings, printed atop textbook chapter headings,
memorized and scrawled on classroom blackboards like a magical
incantation or a Buddhist koan.  But they are absolutely powerless to
even compute the normal force that a bowl of soup exerts on my dinning
room tabletop.

Does Einstein try anywhere to explain the illicit double use of curved
spacetime in his explanation of the 1.75" bending of starlight at the
lim?  To wit, he attributes 87.5" to Newtonian gravity (whose cause we
are taught is spacetime curvature and already baked in to Newtonian
gravity) and then he goes and attributes another 87.5" to  spacetime
curvature.  So he is actually resorting to spacetime curvature twice. 
Even a high schooler would have had the common sense to unify the
curvature of starlight into one agency, instead of two--one of which is
derivative of the other.  Silly.
