Signature of former owner on front flyleaf, else Near Fine, in very good dust jacket. Lectures in Applied Mathematics, Proceedings of the Summer Seminar, Boulder, Colorado, 1960, Volume I. 'Uhlenbeck had a very significant influence on statistical mechanics and brought an area which was very varied and disjointed into some sort of structured whole' (MacTutor History of Mathematics Web site). 'He was an inspiring teacher. With superbly organised and extremely clear lectures, he laid bare for everyone to see the beautiful structure of statistical mechanics, based on the principles of the founding fathers, Maxwell, Boltzmann, and Gibbs. Thus he transmitted to a younger generation what he conceived to be the essence of the past and the way to the future. In doing so, he educated several generations of physicists in statistical mechanics in a style rare in this century' (E.G.D. Cohen, 'George E. Uhlenbeck and statistical mechanics', Amer. J. Phys. 58 (7), 1990, 619-625). …

London, Macmillan, volume 117 No. 2938; the Uhlenbeck is on pp. 264-265 in the issue of pp257-292 February 20, 1926. Nice clean copy, extracted from a larger bound volume. VG $200 This is "the key paper announcing the discovery of spin" (Complete DSB online). [++] This paper is followed by an interesting note by Bohr on pg 265. [++] "In January 1925 Wolfgang Pauli had proposed that the electron should be given an additional fourth quantum number which was a half integer. This was one of the clues which led Uhlenbeck to arrive at the idea of electron spin. The concept immediately excited Niels Bohr, Pauli, Einstein, Heisenberg and others interested in quantum theory. In mid-September 1925, Uhlenbeck and Goudsmit discovered the spin on the electron, which posits an intrinsic angular momentum for all electrons."--SciHi Blog.…

Berlin, Springer, 1925. Royal8vo. Bound in contemporary half cloth with paper label with handwritten title to spine. In "Die Naturwissenschaften", Vol. 30, 1925. Library stamp to title page, otherwise fine and clean. Pp. 953-954. [Entire volume: XXIII, (1), 1092, 44 pp.]. First printing of this landmark paper in which electron spin was first announced. "Ehrenfest had suggested that he work with a fellow student, Goudsmit, who already was an expert on atomic spectra. The two of them wrote a paper on the spectrum of hydrogen, giving an improved interpretation involving half-integer quantum numbers. Then came their great discovery: electron spin. The quantum numbers they had assigned implied that the electron must have another degree of freedom" it must be rotating. With this idea everything fell into place. They published first a short note and then, at the encouragement of Niels Bohr, who visited Leiden shortly after their discovery, a longer paper that appeared in Nature. The origin of the spin-orbit interaction was apparently suggested by Albert Einstein, who also visited Leiden at the time and pointed out that in its rest frame, the electron sees an orbiting nucleus and hence a magnetic field. There remained an awkward factor of two in the spin precession rate. This was soon explained as a relativistic effect in an elegant paper by Llewellen H. Thomas. In their third and final paper on electron spin, Goudsmit and Uhlenbeck summarized these results and gave what has become the accepted interpretation of electron spin and atomic spectra." (DSB)The discovery of electron spin was proposed as an explanation for the Stern-Gerlach experiment. In this experiment a beam of silver atoms was allowed to pass through an inhomogeneous magnetic field. When the magnetic field was on, the beam of silver atoms split into two parts, one deflected up and the other deflected down. In 1925, Uhlenbeck and Goudsmit, both graduate students at the time, proposed an explanation for the Stern-Gerlach experiment by postulating that the electron possesses an intrinsic angular momentum, referred to as "spin".This intrinsic angular momentum gives rise to a magnetic moment in the electron that interacts with magnetic fields. The electron spin and the related magnetic moment are quantized such that there are only two possible discrete values. This quantization of the magnetic moment is what leads to the deflection of the beam of silver atoms either up or down in the inhomogeneous magnetic field. Their insight furnished a missing link leading to the final triumph of the then-struggling birth of quantum mechanics.…
