Paperback. Condizione: New. Print on Demand. This book explores the theoretical foundations of early quantum theory, focusing on how it relates to the behavior of atomic and molecular systems. The author, writing in the late 1910s and early 1920s, was one of the key architects of quantum theory, and this book represents a significant contribution to the field. The author begins by discussing the fundamental principles of quantum theory, including the concept of stationary states, the quantization of energy, and the wave-particle duality of matter. He then applies these principles to the study of atomic and molecular systems, deriving equations that can be used to calculate the energy levels and spectra of these systems. The book concludes with a discussion of the implications of quantum theory for our understanding of the nature of matter and radiation. Overall, this book provides a valuable insight into the development of quantum theory and its application to the study of atomic and molecular systems. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.

Paperback. Condizione: New. Print on Demand. This book delves into the fascinating world of atomic structure, specifically focusing on the hydrogen spectrum. Building on the groundbreaking work of Rutherford and Planck, the author examines the quantum theory of line spectra and its application to understanding the emission of light by hydrogen atoms. The book explores the relationship between the frequencies of light emitted by hydrogen and the motion of the electron within the atom, using classical mechanics and the principles of quantum theory. The author presents a detailed explanation of how the hydrogen spectrum can be interpreted through the concept of stationary states, where the electron occupies specific energy levels within the atom. This work connects the hydrogen spectrum to the broader field of atomic physics and offers a theoretical framework for understanding the behavior of atoms and the emission of light. By delving into the details of atomic structure and the emission of light, this book provides valuable insights into the fundamental nature of matter and the role of quantum theory in explaining its behavior.

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 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 bearing" in testing how well he could summarize what was known, he found occasion to check the soundness of his ideas and to improve their formulation. In the present case, however, he could hardly keep pace with the growth of the subject the paper he had in mind at the beginning developed into a four-part treatise, 'On the Theory of Line Spectra', publication of which dragged over four years without being completed" the first three parts appeared between 1918 and 1922, and the fourth, unfortunately, was never published. Thus, the full impact of Bohr's view remained confined to the small but brilliant circle of his disciples, who indeed managed better than their master to make them more widely known by the prompter publication of their own results" (D.S.B. 2: 246-47).

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 which owed so much to one principle as quantum mechanics owed to Bohr's correspondence principle" (Jammer 1966, p. 118). The evolution of quantum theory is divided into two distinct periods" from 1900 to 1925, usually referred to as the period with the old quantum theory still grounded in classical physics and the second period with quantum mechanics from 1925 onwards. The general rules of quantum mechanics are very successful in describing objects on an atomic level. But macroscopic systems are accurately described by classical theories like classical mechanics and classical electrodynamics. If quantum mechanics were to be applicable to macroscopic objects, there must be some limit in which quantum mechanics reduces to classical mechanics. Bohr's correspondence principle demands that classical physics and quantum physics give the same answer when the systems become large. "A major tool he developed for dealing with quantum problem, [.], was the correspondence principle, which establishes links between predictions of the classical theory and expectations for the quantum theory." (Pais, Niels Bohr's Times, p. 20.). In this sense, the correspondence principle is not only an exceedingly important methodological principle, it also represents the transition to quantum mechanics and modern physics in general and it became the cornerstone of Bohr's philosophical interpretation of quantum mechanics which later would be closely tied to his thesis of complementarity and to the Copenhagen interpretation. Another version of the correspondence principle lives on in philosophical literature where it has taken form as a more general concept representing a development of new scientific theories."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 bearing" in testing how well he could summarize what was known, he found occasion to check the soundness of his ideas and to improve their formulation. In the present case, however, he could hardly keep pace with the growth of the subject the paper he had in mind at the beginning developed into a four-part treatise, 'On the Theory of Line Spectra', publication of which dragged over four years without being completed" the first three parts appeared between 1918 and 1922 [of which the two first from 1918 are offered here], and the fourth, unfortunately, was never published. Thus, the full impact of Bohr's view remained confined to the small but brilliant circle of his disciples, who indeed managed better than their master to make them more widely known by the prompter publication of their own results" (D.S.B. II: 246-47).Inscribed to "Hr. Docent D. la Cour/ Venskabeligst/ fra/ Forfatteren" on both front wrappers. The renowned Danish physicist and meteorologist Dan la Cour (1876-1942), was the son of the great Poul la Cour (1846-1908), who is considered the "Danish Edison". Dan la Cour was the assistant of Niels Bohr's father, Christian Bohr, and a well known scientist. From 1903, he was head of the department of the Meteorological Institute, and from 1923 leader thereof. From 1908 he was Associate Professor at the Polytechnic College. His original scientific works are highly respected, as are his original apparati for measuring earth magnetism which are considered highly valuable. "His original intelligence, which in many ways resemble that of his father, also bore fruit in his patenting of various inventions: the "Pyknoprobe", developed to quickly determine the different layers of the sea" a use of termite in quickly heating food and drinks out in the open under unfavourable weather conditions." (From the Danish Encyclopaedia - own translation). He wrote a number of important and esteemed works and was member of the Danish Scientific Academy as well as many prominent international scientific commissions of meteorology and geophysics (i.e. president of the International Geodetical and Geophysical Union). He was also honorary Doctor at the George Washington University. Rosenfeld, Bohr-Bibliography, 15.

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 bearing" in testing how well he could summarize what was known, he found occasion to check the soundness of his ideas and to improve their formulation.

Thus, the full impact of Bohr's view remained confined to the small but brilliant circle of his disciples, who indeed managed better than their master to make them more widely known by the prompter publication of their own results" (D.S.B. 2: 246-47).The present second part deals with the hydrogen spectrum, whereas the first part dealt with the general theory, and the third with the spectra of elements of higher atomic structure. Peter Kristian Prytz (1851-1929), to whom the work is inscribed, was an important physicist of the generation before Bohr. He did immense work to better the conditions of the teaching of physics at the Polytechnic Institute in Copenhagen, where Bohr studied for many years and where he later became a teacher. Prytz introduced the teaching of experimental physics here and fought for more space, more apparatus, more money for teaching assistance and more time for teaching. Thus, he played a great role in the physics-environment in Copenhagen both during Bohr's years as a student and as a teacher.Most importantly, it was Prytz who (in 1907) attracted the necessary money for the institute which enabled him to create the physical laboratory that constituted the foundation of Danish experimental physics, the field of which Bohr became professor in 1916 (till 1920 - the years during which he was working on the "On the Quantum Theory of the Line Spectra").Rosenfeld, Bohr-Bibliography, 15.
