EINSTEIN, ALBERT. 1879-1955.
Typed Letter Signed ("A. Einstein") with Autograph Postscript, in German, 2 pp recto and verso, 4to, Berlin, October 19, 1928, on personal letterhead, to Dr. Hans Reichenbach, two-hole punch at left margin, two tiny edge-tears at folding creases.
UNPUBLISHED LETTER DISCUSSING RELATIVITY. Einstein writes to Reichenbach (1891-1953), a colleague and important expositor of Relativity, to suggest to him a clearer way of explaining one aspect of his theory. He opens the letter by saying (in translation): "I think the logical presentation that you give of my theory is indeed possible, but it's not the simplest one." After providing a list of four possibilities for "increasing specialization regarding the distant comparison of vectors" he comments: "Of course one can also start with an affine connection and specialize either by introducing a metric or by introducing integrability conditions; i.e. do it the way you did. But this is less simple, less natural." He goes on to assert that "[t]he naturalness of the field of structure envisaged by me seems indisputable to me. I will only know in a few months whether this construction contains deeper traits of reality; for the problems needed to be solved to make this decision are not at all easy." The letter ends with a postscript in Einstein's hand, inviting Reichenbach and his wife to tea, noting "Schrödinger is supposed to come as well."
