Linguistic Copenhagen Interpretation Of Quantum Theory

Linguistic Copenhagen Interpretation of Quantum Theory

Various interpretations of quantum mechanics have been proposed such as the Copenhagen interpretation and the many-worlds interpretation. The linguistic Copenhagen interpretation in this book is a kind of the Copenhagen interpretation derived from von Neumann's formulation of quantum mechanics on Hilbert spaces. Von Neumann had the widest coverage of any mathematician of his time, integrating pure and applied sciences and making major contributions to many fields, including mathematics, physics, economics, computing, and statistics. He was not a genius who specialised only in mathematics and physics, but an all-round genius. From this fact we are tempted to expect the following. (#1) the quantum theory generated from the linguistic Copenhagen interpretation called Quantum Language (QL) is a very large theory that includes not only quantum mechanics of physics but also classical statistics. More generally we may say (#2) QL is the scientific realisation of the dualistic idealism of philosophy. In this book I devote myself to proving (#1). QL consists of two axioms (measurement and causality) and the linguistic Copenhagen interpretation. I first prove von Neumann-Lüders projection postulate in QL. This is a solution in QL, and it is undecided whether it is a physical solution, but the theorem allows QL to be discussed without being interfered by various paradoxes (e.g., Schrödinger's cat, etc.). Also, recall that there are no axioms in statistics. This means that we do not yet have 'theoretical statistics'. However, if we consider that QL for classical systems = theoretical statistics, we can then introduce an elegant understanding into statistics. In most books of statistics, Fisher's maximum likelihood method is not given a due treatment. From the quantum linguistic point of view, the most basic arguments are Fisher's maximum likelihood method and regression analysis. They are strongly linked to the measurement and causality axioms, respectively. As modern statistics continues to develop rapidly in the direction of application now, it is essential to take an overview of statistics as a whole under an umbrella of theoretical statistics. For (#2), refer to my previous book (i.e., History of Western Philosophy from a perspective of quantum theory- Introduction to theory of everyday science– Shiho-Shuppan Publisher, 425 p. (2023)). Throughout this book as wall as the one above, I assert that von Neumann's formulation of quantum mechanics should not be confined in physics, but should be regarded as a fundamental theory of science.

Quantum Mechanics

Why does one theory "succeed" while another, possibly clearer interpretation, fails? By exploring two observationally equivalent yet conceptually incompatible views of quantum mechanics, James T. Cushing shows how historical contingency can be crucial to determining a theory's construction and its position among competing views. Since the late 1920s, the theory formulated by Niels Bohr and his colleagues at Copenhagen has been the dominant interpretation of quantum mechanics. Yet an alternative interpretation, rooted in the work of Louis de Broglie in the early 1920s and reformulated and extended by David Bohm in the 1950s, equally well explains the observational data. Through a detailed historical and sociological study of the physicists who developed different theories of quantum mechanics, the debates within and between opposing camps, and the receptions given to each theory, Cushing shows that despite the preeminence of the Copenhagen view, the Bohm interpretation cannot be ignored. Cushing contends that the Copenhagen interpretation became widely accepted not because it is a better explanation of subatomic phenomena than is Bohm's, but because it happened to appear first. Focusing on the philosophical, social, and cultural forces that shaped one of the most important developments in modern physics, this provocative book examines the role that timing can play in the establishment of theory and explanation.
