Zur Theorie der Lichtfortpflanzung in dispergierenden Medien.

Berlin: Sitzungsberichten der Preussischen Akademie der Wissenschaften, 1922.

First Thus. Einstein, Albert (1879-1955). Zur Theorie der Lichtfortpflanzung in dispergierenden Medien. Complete. Quarto. Offprint from Sitzungsberichten der Preussischen Akademie der Wissenschaften. Berlin: 1922. First edition in very fine condition. This superb offprint is a separate printing of the Prussian Academy's session reports, here with independent pagination. A small number of such off prints were presented to the author by the publisher as voucher copies. References: Schilpp-Shields 162; Weil 120. This paper gives evidence that Einsteins ideas on the photon were not able to contradict classical theory. "Since, after 1917, Einstein firmly believed that light-quanta were here to stay, it is not surprising that he would look for new ways in which the existence of photons might lead to observable deviation from the classical picture. In this he did not succeed. At one point, in 1921, he thought he had found a new quantum criterion, but it soon turned out to be a false lead [as demonstrated in this paper]". An excellent example. "The early Offprints from "Sitzungsberichten." are called "Sonderabdruck" up to Weil No.165 (including this). From Weil 166 they are called "Sonderausgabe.". - Before 161 (up to 160) the Offprints do not have separate title and pagination (the pagination follows the numbering in the periodical). From 166 the Offprint has both separate printed title and pagination. - ( So Weil Nos 161-165 is still "Abdruck", but with separate title and pagination)."
