Soft cover. Condition: As New. 8vo (21.5 cm), XII, 646 pp. Laminated wrappers. "This superb text by David Bohm, formerly Princeton University and Emeritus Professor of Theoretical Physics at Birkbeck College, University of London, provides a formulation of the quantum theory in terms of qualitative and imaginative concepts that have evolved outside and beyond classical theory. Although it presents the main ideas of quantum theory essentially in nonmathematical terms, it follows these with a broad range of specific applications that are worked out in considerable mathematical detail." (from the blurb).

Hardcover. Condition: Very Good. No Jacket. 1st Edition. With previous owner's name and bookplate, otherwise a VG hardcover first edition, 11th printing copy, gray cloth binding, no DJ. As a retired physicist I still try to keep up and I see lots of recent interest in Bohm's pilot wave theory. Bohm obtained his Ph.D. under J. Robert Oppenheimer at the University of California, Berkeley. Due to his Communist affiliations, he was the subject of a federal government investigation in 1949, prompting him to leave the U.S.

In two previous papers (vol 85, 1952) a causal interpretation of the quantum theory was developed which involved the hypothesis that a quantum-mechanical system contains a precisely defined particle variable x but that, at present, we are restricted to calculating the probability density P(x, t) that the particle is at the position x. It was shown that the assumption that P(x, t)=|?(x, t)|2 is consistent, in the sense that if it holds initially, the equations of motion of the particles will cause this relation to be maintained for all time. In this paper, we extend the theory by showing that as a result of random collisions, an arbitrary probability density will ultimately decay into one with a density of |?(x, t)|2. Since all quantum-mechanical experiments to date have been concerned with statistical ensembles of systems that have been colliding with other systems for a very long time, it is therefore inevitable that as we draw samples from such ensembles. - Sprache: Englisch Gewicht in Gramm: 3000.

Blue Cloth. Condition: Very Good. Dust Jacket Condition: No dj. First Thus Edition. Binding sound and tight, text free of markings or such. Offsetting to endpapers, a few minor freckles to the top edge. Titling ver dulled to spine, top and bottom ends have minor rubbing and a bump to top right corner. Fro0nt and rear boards clean en ough with the odd minor mark. At the base of the rear board are two punch holes where it appears someone has driven in a couple of small pins. It does not spoil the appearance of the book and we cannot figure out the purpose behind this. The edition states "reprinted, 1954". This could possible refer to the British edition being a reprint of the 1951 US edition and therefore the first Constable printing. Not a common printing in any case. ix+646pp. Size: 8vo.

David Bohm was an American-Brazilian-British scientist who has been described as one of the most significant theoretical physicists of the 20th century and who contributed unorthodox ideas to quantum theory, neuropsychology and the philosophy of mind. Among his many contributions to physics is his causal and deterministic interpretation of quantum theory, now known as De BroglieBohm theory.

Soft cover. Condition: Near Fine. 1st Edition. First edition, complete journal issues in original printed wrappers, of the Aharonov-Bohm effect. In classical electromagnetic theory, all electromagnetic effects on charged particles can be obtained from a knowledge of the electric and magnetic fields 'seen' by the particle, that is, the fields at the position of the particle; the electromagnetic vector potential A is introduced purely as an auxiliary function to simplify some of the calculations. However, in quantum mechanics the situation is different. Consider an experimental arrangement in which a solenoid, regarded here as of infinite length, carries a finite steady current. The magnetic field produced by the current is entirely confined to the interior of the solenoid; outside it is zero. Now consider a beam of electrons which is split so as to pass on either side of the solenoid, and detected on a screen behind it. According to a quantum-mechanical calculation, the position of the interference fringes observed on the screen should depend on the current in the solenoid, despite the fact that there are no electric or magnetic fields at any point on the trajectories of the electrons! This strange behavior, usually known as the Aharonov Bohm effect, can be interpreted as showing either that the electrons can 'feel' fields even at points they never travel to, or that the vector potential has a 'physical reality' not envisaged in the classical electromagnetic theory. The Aharonov Bohm effect is important conceptually because it bears on three issues apparent in the recasting of (Maxwell's) classical electromagnetic theory as a gauge theory, which before the advent of quantum mechanics could be argued to be a mathematical reformulation with no physical consequences. The three issues are: whether potentials are "physical" or just a convenient tool for calculating force fields; whether action principles are fundamental; the principle of locality. Because of reasons like these, the Aharonov Bohm effect was chosen by the New Scientist magazine as one of the 'seven wonders of the quantum world'. Large 8vo, pp. 485-764.

Soft cover. Condition: Very Good. 1st Edition. First edition, complete journal issue in original printed wrappers, of Bohm's deterministic "hidden variables" approach to quantum theory. "Bohm's primary contribution to Quantum Theory lies in his attempt to construct an ordinary reality interpretation in terms of 'hidden variables.' Bohm considered this interpretation of Quantum Theory to be a significant advance in the development of the theory, one that might appease the many critics who, having aligned themselves with Einstein, still maintained that Quantum Theory is incomplete. This claim as to the possible existence of 'hidden variables' would serve as a springboard for future analysis and experimentation by people like Bell and Aspect, who would be instrumental in finally closing the book on the completeness debate" (Dolling et al., The Tests of Time). "Bohmian mechanics, which is also called the de Broglie-Bohm theory, the pilot-wave model, and the causal interpretation of quantum mechanics, is a version of quantum theory discovered by Louis de Broglie in 1927 and rediscovered by David Bohm in 1952. It is the simplest example of what is often called a hidden variables interpretation of quantum mechanics. In Bohmian mechanics a system of particles is described in part by its wave function, evolving, as usual, according to Schrödinger's equation. However, the wave function provides only a partial description of the system. This description is completed by the specification of the actual positions of the particles. The latter evolve according to the guiding equation, which expresses the velocities of the particles in terms of the wave function. Thus, in Bohmian mechanics the configuration of a system of particles evolves via a deterministic motion choreographed by the wave function. In particular, when a particle is sent into a two-slit apparatus, the slit through which it passes and its location upon arrival on the photographic plate are completely determined by its initial position and wave function. Bohmian mechanics inherits and makes explicit the nonlocality implicit in the notion, common to just about all formulations and interpretations of quantum theory, of a wave function on the configuration space of a many-particle system. It accounts for all of the phenomena governed by nonrelativistic quantum mechanics, from spectral lines and scattering theory to superconductivity, the quantum Hall effect and quantum computing. In particular, the usual measurement postulates of quantum theory, including collapse of the wave function and probabilities given by the absolute square of probability amplitudes, emerge from an analysis of the two equations of motion: Schrödinger's equation and the guiding equation. No invocation of a special, and somewhat obscure, status for observation is required" (Stanford Encyclopedia of Philosophy). Large 8vo. Original printed wrappers.

Wraps. Condition: Very Good. First Edition. The Aharonov-Bohm effect is the quantum mechanical phenomenon that allows a charged particle to be affected by an electromagnetic field that does not exist in the vicinity of the particle, one of the stranger manifestations of quantum mechanics. This paper first predicted and described this phenomenon. First Printing. 485-764 pp. 4to. Green paper wraps that are clean and crisp. Red ink library stamp on the cover.
