1925réf. 48025Berlin Julius Springer 1925. Contemp. hcloth. Gilt lettering to spine. In: "Zeitschrift für Physik. Hrsg. von Karl Scheel" 32. Band. VI951 pp. textillustr. Entire volume offered. Heisenberg's paper: pp. 841-860. A small erased stamp on titlepage leaving two small holes no loss of text. Internally clean. First appearance of Heisenberg's importent paper on the complex spectra of many-electron atoms - the third paper Heisenberg submitted from Copenhagen on the Quantum Theory."The paper on multiplet structure and anomalous Zeeman effects. contained a complete discussion of the problem at that time. This paper had the blessing of Niels Bohr; also Pauli who wasin Copenhagen when the paper was completed agreed with its overall content. The central goal of the paper was to formulate what Bohr called 'the stress constraint which is not analogous to the action of external forces' and to derive quantitative conclusions from it." Mehra and rechenberg "The Historical development of Quantum Theory" vol. 2 p. 201.The volume contains another importent paper in the history of Quantum Physics: W. BOTHE und H. GEIGER "Über das Wesen des Comptoneffekts ein experimenteller Beitrag zur Theorie der Strahlung" pp. 639-663. hardcover

1804réf. 42887London W. Bulmer and Co. 1804. 4to. No wrappers as extracted from "Philosophical Transactions" 1804 - Part II. Pp. 313-345. Clean and fine. First appearance of an importent paper in which Hatchett communicates his discovery that iron must be combined with a large portion of either carbon phosphorus or sulphur in order to acquire the property of receiving permanent magnetic virtue there being however a limit beyond which an excess of either of the above-named substances renders the compound wholly incapable of exhibiting the magnetic energy.Together with another paper by Patrick Russell: "Remarks on the voluntary Expansion of the Skin of the Neck in the Cobra de Capello or booded Snake of the East Indiea. With a Description of the Structure ofthe Parts which perform that Office. By Everard Home." Pp. 346-352 a. 2 large engraved plates showing the snake. unknown
1837réf. 42610London Richard and John E. Taylor 1837. 4to. No wrappers as extracted from "Philosophical Transactions" 1837 - Part II. Pp. 347-363. Clean and fine. First printing of Dalton's last paper submitted to the "Transactions". This paper one of his last deals with the constitution of the atmosphere just as his first love was meteorology."In an essay of mine on the constitution of the atmosphere which was printed in the Transactions for 1826 I signified my intention of following it with a sequel of experiments to ascertain if possible which of the two views therein developed was most counntenanced by facts. I now proceed to give an account of such investigations relating to this subject as havee engaged my attention during a long period of years."John Dalton. - Smith: John Dalton. A Bibliography. No. 78. unknown
