Two-body problem in general relativity theory"

Lancaster, PA: American Physical Society, 1 March 1936. Second series, volume 49, number 5. Very Good. ppl 341-422. Original green wraps. Slight nick at bottom edge of lower wrap, else better than very good.

Includes the retort by Einstein and Rosen (originators of speculation on the existence of "worm-holes" in spacetime) to objections made to the general theory of relativity. According to Galina Weinstein: "Between 1935 and 1936, Einstein was occupied with the Schwarzschild solution and the singularity within it while working in Princeton on the unified field theory and with his assistant Nathan Rosen, on the theory of the Einstein-Rosen bridges. He was also occupied with quantum theory. He believed that quantum theory was an incomplete representation of real things. Together with Rosen and Boris Podolsky he invented the EPR paradox. I demonstrate that the two-body problem in general relativity was a heuristic guide in Einstein's and collaborators' 1935 work on the Einstein-Rosen bridge and EPR paradox."
