Einsein Letter on SR and GR

I'm good on my word so when I said I'd post the original letter by Einstein o Lincoln Barnette I meant it so here it is. Please see attachment.

In essence Einstein stated in no uncertain terms that gravity should not be thought of as a curvature of spacetime. Spacetime curvature is just the relativistic term for tidal gradients. He also stated the relativity does not geometrize physics anymore that EM or the distance between two points.

Thanks, I will read it carefully.

Having an (typed) English translation of the German is really useful.

I have to admit I can't read Herr Prof. Einstein's handwriting at all well.



I also have to admit I have no idea what the controversy of 'Geometry' is about, so I am completely with him in that respect.

In any case it depends upon ones definitions of Geometry, and to a lesser extent, Field, since both have been changed and/or extended over the course of the 20th century.
