Here Roland Omnès offers a clear, up-to-date guide to the conceptual framework of quantum mechanics. In an area that has provoked much philosophical debate, Omnès has achieved high recognition for his Interpretation of Quantum Mechanics (Princeton 1994), a book for specialists. Now the author has transformed his own theory into a short and readable text that enables beginning students and experienced physicists, mathematicians, and philosophers to form a comprehensive picture of the field while learning about the most recent advances. This new book presents a more streamlined version of the Copenhagen interpretation, showing its logical consistency and completeness. The problem of measurement is a major area of inquiry, with the author surveying its history from Planck to Heisenberg before describing the consistent-histories interpretation. He draws upon the most recent research on the decoherence effect (related to the modern resolution of the famous Schrödinger's cat problem) and an exact formulation of the correspondence between quantum and particle physics (implying a derivation of classical determinism from quantum probabilism). Interpretation is organized with the help of a universal and sound language using so-called consistent histories. As a language and a method, it can now be shown to be free of ambiguity and it makes interpretation much clearer and closer to common sense.

Written in an informal yet substantive style that is a joy to read, this book provides a uniquely engaging, in-depth introduction to the concepts of quantum physics and their practical implementation, and is filled with clear, thorough explanations that help readers develop insight into physical ideas and master techniques of problem-solving using quantum mechanics. Fully explores the concepts and strategies of quantum mechanics, showing the connections among the physical concepts that govern the atomic and sub-atomic domain of matter, and examining how these concepts manifest themselves in the mathematical machinery of quantum mechanics. Focuses on the explanations and motivations of the postulates that underlie the machinery of quantum mechanics, and applies simple, single-particle systems in one dimension. Illuminates discussions of ideas and techniques with a multitude of examples that show not just the answers but also the reasoning behind them, and adds dimension to the subject with historical, biographical and philosophical references throughout. Designed for a wide range of readers interested in various branches of physics and engineering physics.
Understanding Quantum Physics
After the formulations of Newton and Maxwell theories, it seemed that nothing else could alter the path taken in the Physical description of natural phenomena.The principle of causality well described the electromagnetic phenomena and the motion of celestial bodies, from a deterministic point of view.With the formulation of the Theory of relativity, Einstein continued the path of description of the phenomena in motion even at speeds comparable to the one of light.The change began with the in-depth and studies at the atomic level where, Planck, Bohr and Einstein abandoned the concept of continuity in favor of the introduction of the matter's quantization, however, continuing to interpret the phenomena always with a classical foundation.The contribution of the young Heinsenberg and Schoidenger will be necessary to definitively abandon the classical interpretation in order to introduce the shocking interpretation of the new quantum The subsequent formalization of quantum mechanics based on non-commutative algebra, introduced by the young Dirac continued the path towards the definitive use of quantum theory in the microscopic world.With quantum physics we discover a whole new way of matter and light behaviour in the microcosm realm.Grammatically it could be necessary to just invert one consonant for a vocal: going from causality to casuality.An atom is no longer made up of electrons orbiting like planets and it no longer has a defined trajectory with certain values of speed and position.Quantum physics describe the microcosm praising an evolution of nature towards disorder and uncertainty, rather than a deterministic vision established by cause and effect, dominant in classical physics.The particles can transmit instant information between themselves, beyond the limit of the speed of light, imposed by Einstein with the formulation of the special Relativity Theory.Understanding the behavior of matter at the atomic level will lead you to important reflections, and to finally think that nothing that surrounds us can be more interpreted with deterministic rationality alone. To comprehend the fabolous world of quantum physics It is possible to find hundreds of books, but most of the time they are either too popular or are treated at university level.With the present exposition, instead, I tried to deal with these themes making you understand principally the concepts, without however neglecting the rigorous mathematical formulas and demonstrations, with a language that can be interpreted with mathematical and physical skills that are learned in a high school.The present text does not claim the prerogative of being exhaustive in the interpretation of quantum theory, but it is certainly useful for acquiring notions in order to be able to understand from a scientific point of view the texts on the market of a popular nature regarding this subject and in any case creating excellent conditions for future in-depth university studies.I thank all those who have been close to me during the writing of the present discussion and with the hope of having set the work that could be useful to those who are approaching the study of the fascinating world of Quantum Physics. I am grateful since now to those who want to propose improvements or possible suggestions.
