Buch. Condition: Neu. Neuware - Volume 7 is a direct continuation of Volume 6, which documented the birth of the complementarity argument and its earliest elaborations. It covers the extension and refinement of the complementarity argument from 1933 until Bohrs' death in 1962. All Bohr's publications on the subject, together with selected manuscripts and extracts of his correspondence with friends and fellow pioneers such as Werner Heisenberg and Wolfgang Pauli, are included.Divided into two, largely independent parts, the volume begins with Bohr's contributions to 'Relativistic Quantum Theory'. Together with Léon Rosenfeld, Bohr undertook a thorough investigation of the measuring problem in quantum electrodynamics and demonstrated the full accordance between the formalism and the result of idealized thought experiments.The articles in the second part, although also restricted in scope to the field of physics, address a broader audience. One of the most impressive treatises is Bohr's own account of his debates with Albert Einstein, over more than twenty years, on the consistency, the completeness and the epistemological consequences of quantum mechanics.Volumes 6 and 7 of the Collected Works are in turn related to the forthcoming Volume 10 which broadens the scope by presenting Bohr's applications of the complementarity argument beyond the domain of physics. Although each volume may be read independently, careful attention should be paid to the interrelationships between each volume in order to appreciate the subtlety of Bohr's continued elaboration and fine-tuning of his complementarity argument.…

orig.wrappers. 24x16cm, 138 pp., Some small tears to wrapper edges. University of Copenhagen doctoral dissertation. Includes a 12-page English summary. Inscribed by author on half-title: "Hr. og Fru Crawford / med venlig hilsen / fra forf." ["..a Danish biochemist who pioneered the study of cellular respiration. Kalckar made a number of significant contributions to the development of 20 th century biochemistry including: a founder of bioenergetics; enzymology, including novel assay techniques; galactose metabolism in both microorganisms and animal tissues; suggestion that strontium-90 levels in children's deciduous teeth correlated with nuclear testing..Kalckar completed his medical training at the University of Copenhagen in 1933, and then began research for his Ph. D. in Ejnar Lundsgaard's physiology laboratory; that work established the foundation of a fundamental biochemical paradigm, i.e. 'oxidative phosphorylation'. During this period, Lundsgaard was preoccupied as physiology department chair, consequently Fritz Albert Lipmann, who had recently fled Germany, served as Kalckar's research mentor. Later, Kalckar and Lipmann both independently developed concepts of a 'high energy bond' . ..Kalckar's breakthrough work was the demonstration that organic compounds, which were phosphorylated during metabolic processes, involved oxygen consumption; oxygen consumption was linked to organic compound phosphorylation. His key experiment demonstrated that in frog muscles where glycolysis had been inhibited with iodoacetate, muscular contraction continued for a short period using phosphocreatine as a source of energy. Kalckar referred to this process as 'aerobic phosphorylation' .." -wikipedia]. Rubbed. Spine chipped & torn. Good.…

Copenhagen, Levin & Munksgaard,1937. 8vo. Uncut in orig. printed wrappers. In: "Det KGL. Danske Videnskabernes Selskab. Mathematisk-fysiske Meddelelser. XIV,10". 40 pp. Fine and clean. First edition of the work in which Bohr introduced his famous Liquid Drop Model of the atom in order to interprete the nuclear structure. (The paper was not continued as Kalckar died the following year)."It had, of course, been clear to Bohr that analogies with atomic spectra could not be of help in interpreting his (earlier) picture of nuclear structure. Peripheral electrons, thinly spread within the atomic volume, can be compared to a dilute gas of particles interacting in pairs only. By contrast Bohr's picture of intranuclear motions of tightly bound nucleons should show 'essential collective aspects', he said. Now, together with Kalckar, he suggested that for nuclei a much more proper comparison would be with a drop of liquid. That analogy should not be taken too literally, the dynamics of a true liquid drop is vastly different from thta of nucleai. Yet the comparison, treated cautiously, was tempting and in the event proved fruitful in many respects, particularly in regard to collective motions."(Pais "Niels Bohr's Times", pp. 339-40)."In the liquid drop model, formulated by Niels Bohr, the nucleons are imagined to interact strongly with each other, like the molecules in a drop of liquid. A given nucleon collides frequently with other nucleons in the nuclear interior, its mean free path as it moves about being substantially less than the nuclear radius. This constant "jiggling around" reminds us of the thermal agitation of the molecules in a drop of liquid. The liquid drop model permits us to correlate many facts about nuclear masses and binding energies" it is useful in explaining nuclear fission. It also provides a useful model for understanding a large class of nuclear reactions." (FAQ).Rosenfeld No 56.…
