MOVING LOCATIONS We are in the middle of moving our shop. Our Collections of books are packed and will not be unpacked for about a month. We will still take Clamshell orders but delivery may take a bit longer but we can still accept these orders and produce the cases for you all. Specific arrangements can be made. Thank you for your understanding and thank you for your patronage.

A fine fresh example (small pencil mark to upper wrapper) of THIS RARE PAPER!! - ."Although Einstein could not accept Weyl's theory as a physical theory, he cherished "its courageous mathematical construction" and thought intensively about its conceptual foundation. This becomes clear from his paper "On a complement at hand of the bases of general relativity" of 1921. In it, he raised the question whether it would be possible to generate a geometry just from the conformal invariance of Equation without use of the conception "distance", i.e., without using rulers and clocks. He then embarked on conformal invariants and tensors of gauge-weight 0, and gave the one formed from the square of Weyl's conformal curvature tensor" Hubert, F.M. Goenner, On the History of Unified Field Theories. Reference: Weil N. 116; Schlipp-Shields No.145.
