First printing of one of the papers for which Einstein was awarded the Nobel Prize in 1921. It was for the papers "Ueber einen die Erzeugung und Verwandlung des Lichtes betreffenden heuristischen Gesichtspunkt" of 1905 and "Zur Theorie der Lichterzeugung. Theory of light emission and absorption the offered item that Einstein received the prize: "for his services to theoretical physics and especially for his discoveryof the law of the photoelectrical effect" - his reward was not based on relativity."The quantum theory has affected virtually every branch of physics. Its earliest and one of its most significant developments was Einstein's application of the theory to what is known as the 'photo-electrical effect'.Einstein explained this effext by suggesting that the classical view that light is emitted in the form of continous waves must be abandoned. The photo-electrical effect could be explained only as an example of quantum action where the waves of light or X-rays are emitted in minute particles or bullets. It is he size of the bullet the wave-lenght of the radiation which determines the number of electrons ejected. It was for this and not for the theory of relativity that Einstein was awarded the Nobel Prize in 1921. Einstein's two fundamental papers on this subject are "Ueber einem Erzeugung." 1905 and Zur Theorie der Lichterzeugung the paper offered here" PMM the note to 391.Weil: 12 with an asterix denoting a major paper - Boni:12. unknown

réf. 72537Braunschweig Friedrich Vierweg & Sohn; Berlin J. Springer 1924. 8vo 22.8 x 15.4 cm. 10 pp. Original printed wrappers. = First paper by the Indian physicist Satyendra Nath Bose 1894-1974 on thermal equilibrium in the radiation field in the presence of matter and second paper sent to Albert Einstein with the request to translate and publish it in a German physics journal. Einstein saw the importance of the paper but he disagreed with its contents and decided to add a lengthy comment. Subsequently Bose saw a way to circumvent Einstein's critique but never published this rebuttal. Nearly 50 years later Bose stated that he was disappointed by Einstein's remarks ".Bose had his own approach to quantum theory based on his views about the interconnectedness of spontaneous and induced emissions which formed the subject matter of his second and third papers. He did not agree with Einstein's proposal to treat them as independent physical processes. Stationary states in atoms have zero widths both in the old and the new quantum theories and therefore have infinite life-times whereas in reality they do decay and jump down to lower energy states with a finite life-time. What is the origin of these finite widths In Bose's view they are the consequence of the interaction between atom and environment as he attempted to show in his second and third papers. But Einstein did not agree and dismissed his views with the remark that in a world consisting of a single excited hydrogen atom and nothing else the atom would obviously emit a photon and come down to its ground-state! Einstein did not explain what would excite an atom in such a world. Bose was very disappointed by this simply because the world does have much more than a single hydrogen atom and inevitably every atom has an environment" Wali.

1915réf. 1200Braunschweig: Friedr. Vieweg & Sohn 1915. 1st Edition. FIRST EDITION FULL BOUND VOLUME OF THE EINSTEIN-DE HAAS EFFECT -- an experimental observation that illustrates the relationship between magnetism and angular momentum and in which a change in the magnetic moment causes the rotation of a free body. In this 1915 paper Albert Einstein and Wander de Haas report that changing the magnetization of a suspended iron rod by applying an external magnetic field leads to mechanical rotation of the rod - a result that still stands as a textbook illustration of the relationship between magnetism and angular momentum. Papers by Planck The Quantum Hypothesis for Molecules with Multiple Degrees of Freedom von Laue Warburg Siegbahn and Born are also present. Einstein had long contemplated Ampère's 1820 conjecture that magnetism is caused by the microscopic circular motions of electric charges. In light of this Einstein and de Haas devised an experiment to test not just Ampère's hypothesis but also "Lorentz's theory that the rotating particles are electrons. The aim of the experiment was to measure the torque generated by a reversal of the magnetization of an iron cylinder" Calaprice Einstein Almanac 52. In the experiment Einstein and de Haas designed "a magnetic material was suspended with the aid of a thin string inside a magnetic field coil. When the magnetic field was increased by the application of an electric current through the field coil the magnetic material is magnetized. In order to keep the total magnetic moment of the magnetic material constant the latter rotates. This classical Einstein-de Haas effect demonstrates that the spin angular momentum is of the same nature as the angular momentum of rotating bodies as conceived in classical mechanics" Ganzhorn Nature Communications 7 11443 2016. Einstein spoke enthusiastically of the experimental results he and de Haas has achieved stating that they had "given firm proof of the existence of Ampère's molecular currents" Pais Subtle is the Lord 245. ALSO INCLUDED: Papers by Planck "Die Quantenhypotese für Molekeln mit mehreren Freiheitsgraden" and "Bemerkung über die Entropiekonstante zweiatomiger Gase" as well as a paper by von Laue "Die Einsteinischen Energieschwankungen" CONDITION & DETAILS: Braunschweig: Friedr.

1922réf. 32430Berlin: Sitzungsberichten der Preussischen Akademie der Wissenschaften 1922. First Thus. 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.
