![]() ![]() After having revealed himself as a firm promise in the field of Nuclear Physics, he traveled to England to expand his knowledge at the Cavendish Laboratory of the University of Copenhagen. He studied Physics at the University of Copenhagen, where he obtained his doctorate in 1911. Son of Christian Bohr, a devout Lutheran, professor of physiology at the University of the city, and Ellen Adler, from a wealthy Jewish family of great importance in Danish banking, and in the "circles of Parliament".Ĭonsidered one of the most dazzling figures in contemporary Physics and, for his theoretical contributions and practical work, as one of the fathers of the atomic bomb, he was awarded the Nobel Prize in Physics in 1922 "for his research on the structure of atoms and the radiation emanating from them. In this book we have a remarkable narrative of the genesis, application, reception, and use of one of the pivotal theories of modern physics.Danish physicist who made important contributions to the understanding of the structure of the atom and quantum mechanics. Kragh examines Bohr's atom on its own terms, not merely as a stepping-stone to later quantum theory. Usually exiled to introductory chapters in histories of quantum mechanics, this instantly recognizable model has long needed a focused investigation. "Around the world, the Bohr model of the atom is visually synonymous with "science." Despite its universality, the Bohr atom has waited a hundred years for Kragh's thorough study. Stuewer, History of Science and Technology, University of Minnesota ![]() We have here what promises to be the definitive history of the Bohr theory of the atom." It is unique in emphasizing and documenting that Bohr conceived his theory as a comprehensive theory of the constitution of matter, one that applied to both atoms and molecules, that is, to the domains of both physics and chemistry, whose practitioners responded to it in profoundly different ways. It explores the development of the revolutionary Bohr atom from its birth in 1913 and extensions during the next five years to its supersession by modern quantum mechanics in the mid 1920s, treating at each stage its successes and failures and its positive and negative receptions in Europe and the United States. "This compelling biography of a scientific theory, that of the Bohr atom, is unprecedented and unmatched in depth and breadth. Klaus Hentschel, Professor and Director of the History Department, Stuttgart University Written by an experienced historian of science, it surveys the full breadth of the literature on its history and implications in physics, chemistry, astrophysics and far beyond, including excerpts from many still unpublished sources such as letters or manuscripts. This book is likely to become the definitive history of the development of Bohr's atomic model. ContentsĢ: On the constitution of atoms and moleculesĩ: Appendix: The philosophers' atom Customer Reviews By discussing the theory in its entirety it becomes possible to understand why it developed as it did and thereby to use it as an example of the dynamics of scientific theories. Moreover, it discusses the theory as Bohr originally conceived it, namely, as an ambitious theory covering the structure of atoms as well as molecules. ![]() Contrary to most other accounts of the Bohr atom, the book presents it in a broader perspective which includes the reception among other scientists and the criticism launched against it by scientists of a more conservative inclination. ![]() At the same time it offers new insight into Bohr's peculiar way of thinking, what Einstein once called his 'unique instinct and tact'. Niels Bohr and the Quantum Atom is the first book that focuses in detail on the birth and development of Bohr's atomic theory and gives a comprehensive picture of it. ![]()
