1922. København, Bianco Lunos Bogtrykkeri, 1918 - 1922. 4to. Uncut unopened in the original printed wrappers. In "D. Kgl. Danske Vidensk. Selsk. Skrifter, afd., 8, række IV, 1-3" / "Mémoires de l'Académie Royale des Sciences et des Lettres de Danemark". Wrapper with a few minor nicks and tears but otherwise a very fine and clean copy. 118 pp. Collected offprint-edition of Bohr's seminal work "On the Quantum Theory of the Line-Spectra", marking the beginning of the quantum revolution in physics, introduced the concept of quantized energy levels, provided an explanation for the observed line spectra, and served as a foundational model that inspired further developments in quantum mechanics. It is conseidered one of Bohr's most important papers and the basis for his Nobel Prize. These papers give the first clear formulation of his 'correspondence principle' establishing the limit agreement of quantum and classical physics. "By 1918 Bohr had visualized, at least in outline, the whole theory of… Read More

1918. Copenhagen, Bianco Lunos, 1918. 4to. Original printed wrappers. Lower right corner of front wrapper bent. Small closed tear to front wrapper. Spine strip renewed. Otherwise fine and clean throughtout. First printing of the second part of Bohr's seminal work "On the Quantum Theory of the Line-Spectra" (which appeared in three parts and which was never finished), author's off-print (with "Separate copy" printed on front wrapper), presentation-copy, inscribed by Bohr: "Hr. Professor K. Prytz / med venlig Hilsen / fra Forfatteren"."By 1918 Bohr had visualized, at least in outline, the whole theory of atomic phenomena. ... He of course realized that he was still very far from a logically consistent framework wide enough to incorporate both the quantum postulates and those aspects of classical mechanics and electrodynamics that seemed to retain some validity. Nevertheless, he at once started writing up a synthetic exposition of his arguments and of all the evidence upon which they could have any… Read More

1918. Copenhagen, Bianco Lunos, 1918. 4to. Both parts uncut and in the original printed wrappers. Wrappers detached and with small nicks and tears to extremities. Internally fine and clean. Part I unopened. 36 pp. + pp. (37) - 100. First editions, author's off-prints (with "Separate Copy" printed to front wrappers), presentation-copies, of the first two parts of Bohr's seminal work "On the Quantum Theory of the Line-Spectra" (which appeared in three parts and which was never finished, the third part of which, published 4 years later, is almost never found in presentation-sets), in which Bohr gave his first clear presentation of his groundbreaking "correspondence principle": "Which would play a pivotal role in the later development of atomic theory and its transformation into quantum mechanics." (Kragh, Quantum Generations, p. 56). It eventually became a cornerstone in the quantum mechanics formulated by Heisenberg and Schrödinger. "There was rarely in the history of physics a comprehensive theory… Read More
