Here's a response from my similar Q on sci.math. I believe it is consistent with your cite, altho your cite leaves a few dangling participles, or whatever. ---------------------------------------------------- I have Constance Reid's biography of Hilbert here, so I'll type out part of what it says in Chapter XVII. [ In Gottingen, in the weekly Hilbert-Debye seminars, it seemed to those few students who were left [due to WWI] that the "living pulse" of physical research was at their finger tips. The work of Einstein as he pressed forward toward a general theory of relativity was followed with great interest. Also followed was the work of others who were trying to reach the same goal. Hilbert was especially fascinated by the ideas of Gustav Mie, then in Greifswald, who was attempting to develop a theory of matter on the fundamentals of the relativity principle; and in his own investigations he was able to bring together Mie's program of pure field theory and Einstein's theory of gravitation. At the same time, while Einstein was attempting in a rather roundabout way to develop the binding laws for the 10 coefficients of the differential form which determines gravitation, Hilbert independantly solved the problem in a different, more direct way. Both men arrived at almost the same time at the same goal. As the western front settled down for the winter, Einstein presented his two papers, "On general relativity theory" to the Berlin Academy on November 11 and 25; Hilbert presented his first note on "The foundations of physics" to the Royal Society of Science in Gottingen on November 20, 1915. It was a remarkable coincidence ... but even more remarkable, according to [Max] Born (who was now in Berlin with Einstein), was the fact that it led, not to a controversy over priority, but to a series of friendly encounters and letters. Hilbert freely admitted, and frequently stated in lectures, that the great idea was Einstein's. ] If I remember correctly, it was Georg Pick (discoverer of a famous formula for the area of an affine polygon) who first advised Einstein to make a study of Riemannian geometry. That was in 1911. -------------------------------------------- -- EA |
