  8. Interpreting Bodies Classical and Quantum Objects in Modern Physics.Elena Castellani (ed.) - 1998
    Bewildering features of modern physics, such as relativistic space-time structure and the peculiarities of so-called quantum statistics, challenge traditional ways of conceiving of objects in space and time. Interpreting Bodies brings together essays by leading philosophers and scientists to provide a unique overview of the implications of such physical theories for questions about the nature of objects. The collection combines classic articles by Max Born, Werner Heisenberg, Hans Reichenbach, and Erwin Schrodinger with recent contributions, including several papers that have (...)

    On the Necessity of Including the Observer in Physical Theory.Wolfgang Baer - 2015 - Cosmos and History: The Journal of Natural and Social Philosophy 11 (2):160-174.
    All statements describing physical reality are derived through interpretation of measurement results that requires a theory of the measuring instruments used to make the measurements. The ultimate measuring instrument is our body which displays its measurement results in our mind. Since a physical theory of our mind-body is unknown, the correct interpretation of its measurement results is unknown. The success of the physical sciences has led to a tendency to treat assumption in physics as indisputable facts. (...)

    Sensory Measurements: Coordination and Standardization.Ann-Sophie Barwich & Hasok Chang - 2015 - Biological Theory 10 (3):200-211.
    Do sensory measurements deserve the label of “measurement”? We argue that they do. They fit with an epistemological view of measurement held in current philosophy of science, and they face the same kinds of epistemological challenges as physical measurements do: the problem of coordination and the problem of standardization. These problems are addressed through the process of “epistemic iteration,” for all measurements. We also argue for distinguishing the problem of standardization from the problem of coordination.

    The Estimative Functions of Physical Theory.Paul M. Quay - 1975 - Studies in History and Philosophy of Science Part A 6 (2):125-157.
    Attention is drawn to two closely related functions served by scientific theory which are of fundamental importance in physical science but as yet little discussed in philosophy. As indicated by their names, they constitute the theoretical basis of physical measurements. After analysing some historically important examples and sketching the historical development of these ideas, this paper examines the similarities and differences between the estimate functions of theory and such well-known functions as prediction and explanation. The pervasiveness of (...)

  18. On the Metaphysics of Experimental Physics.Karl Rogers - 2005 - Palgrave-Macmillan.
    This provocative and critical work addresses the question of why scientific realists and positivists consider experimental physics to be a natural and empirical science. Taking insights from contemporary science studies, continental philosophy, and the history of physics, this book describes and analyzes the metaphysical presuppositions that underwrite the technological use of experimental apparatus and instruments to explore, model, and understand nature.

    Mathematics and Measurements for High-Throughput Quantitative Biology.Harald Martens & Achim Kohler - 2009 - Biological Theory 4 (1):29-43.
    Bioscientists generate far more data than their minds can handle, and this trend is likely to continue. With the aid of a small set of versatile tools for mathematical modeling and statistical assessment, bioscientists can explore their real-world systems without experiencing data overflow. This article outlines an approach for combining modern high-throughput, low-cost, but non-selective biospectroscopy measurements with soft, multivariate biochemometrics data modeling to overview complex systems, test hypotheses, and making new discoveries. From preliminary, broad hypotheses and goals, many (...)

    Physical Limits on the Precision of Mitotic Spindle Positioning by Microtubule Pushing Forces.Howard Jonathon & Garzon‐Coral Carlos - forthcoming - Bioessays.
    Tissues are shaped and patterned by mechanical and chemical processes. A key mechanical process is the positioning of the mitotic spindle, which determines the size and location of the daughter cells within the tissue. Recent force and position-fluctuation measurements indicate that pushing forces, mediated by the polymerization of astral microtubules against­ the cell cortex, maintain the mitotic spindle at the cell center in Caenorhabditis elegans embryos. The magnitude of the centering forces suggests that the physical limit on the (...)

  21. Computable Functions, Quantum Measurements, and Quantum Dynamics.M. A. Nielsen - unknown
    Quantum mechanical measurements on a physical system are represented by observables - Hermitian operators on the state space of the observed system. It is an important question whether all observables may be realized, in principle, as measurements on a physical system. Dirac’s influential text ( [1], page 37) makes the following assertion on the question: The question now presents itself – Can every observable be measured? The answer theoretically is yes. In practice it may be very (...)

    Quantum and Concept Combination, Entangled Measurements, and Prototype Theory.Diederik Aerts - 2014 - Topics in Cognitive Science 6 (1):129-137.
    We analyze the meaning of the violation of the marginal probability law for situations of correlation measurements where entanglement is identified. We show that for quantum theory applied to the cognitive realm such a violation does not lead to the type of problems commonly believed to occur in situations of quantum theory applied to the physical realm. We briefly situate our quantum approach for modeling concepts and their combinations with respect to the notions of “extension” and “intension” in (...)

    The Determination of the Past and the Future of a Physical System in Quantum Mechanics.Paul Busch & Pekka J. Lahti - 1989 - Foundations of Physics 19 (6):633-678.
    The determination of the past and the future of a physical system are complementary aims of measurements. An optimal determination of the past of a system can be achieved by an informationally complete set of physical quantities. Such a set is always strongly noncommutative. An optimal determination of the future of a physical system can be obtained by a Boolean complete set of quantities. The two aims can be reconciled to a reasonable degree with using unsharp (...)

    On Relations Between Probabilities Under Quantum and Classical Measurements.Andrei Y. Khrennikov & Elena R. Loubenets - 2004 - Foundations of Physics 34 (4):689-704.
    We show that the so-called quantum probabilistic rule, usually introduced in the physical literature as an argument of the essential distinction between the probability relations under quantum and classical measurements, is not, as it is commonly accepted, in contrast to the rule for the addition of probabilities of mutually exclusive events. The latter is valid under all experimental situations upon classical and quantum systems. We discuss also the quantum measurement situation that is similar to the classical one, described (...)

    The difference between the measurement bases of classical and quantum mechanics is often interpreted as a loss of reality arising in quantum mechanics. In this paper it is shown that this apparent loss occurs only if one believes that refined everyday experience determines the Euclidean space as the real space, instead of considering this space, both in classical and quantum mechanics, as a theoretical construction needed for measurement and representing one part of a dualistic space conception. From this point of (...)

    Protective Measurements and the Meaning of the Wave Function in the de Broglie-Bohm Theory.Shan Gao - unknown
    There are three possible interpretations of the wave function in the de Broglie-Bohm theory: taking the wave function as corresponding to a physical entity or a property of the Bohmian particles or a law. In this paper, we argue that the first interpretation is favored by an analysis of protective measurements.

    Brownian Motion as a Limit to Physical Measuring Processes: A Chapter in the History of Noise From the Physicists’ Point of View.Martin Niss - 2016 - Perspectives on Science 24 (1):29-44.
    In this paper, we examine the history of the idea among physicists that there is a fundamental limit to physical measuring processes and that this limit is set by noise. In contrast to previous studies, that have focused on the realization of the existence of such a limit, we focus on the noise aspect of this history. In his monograph entitled Noise from 1954, the Dutch-American physicist and pioneer of noise Alder van der Ziel described how noise came to (...)

    "Object Theoretic-Operational" View of Physical Knowledge.Arkadiy Lipkin - 2008 - Proceedings of the Xxii World Congress of Philosophy 43:109-116.
    The "object theoretic operational view" suggests a new structure of physical knowledge. This view takes branches of physics as basic units. Its main concepts are primary (PIO) and secondary (SIO) ideal objects with the explicit definition of SIO through PIO and the implicit definition of PIOs within appropriate systems of statements, called a "nucleus of a branch of physics" (NBP). Within an NBP (which has a definite structure) the focus shifts from discovering "laws of nature" to definition of a (...)

    Physical Entropy and the Senses.Kenneth H. Norwich - 2005 - Acta Biotheoretica 53 (3):167-180.
    With reference to two specific modalities of sensation, the taste of saltiness of chloride salts, and the loudness of steady tones, it is shown that the laws of sensation (logarithmic and power laws) are expressions of the entropy per mole of the stimulus. That is, the laws of sensation are linear functions of molar entropy. In partial verification of this hypothesis, we are able to derive an approximate value for the gas constant, a fundamental physical constant, directly from psychophysical (...)

    The Logic of Quantum Measurements in Terms of Conditional Events.Philip Calabrese - 2006 - Logic Journal of the IGPL 14 (3):435-455.
    This paper shows that the non-Boolean logic of quantum measurements is more naturally represented by a relatively new 4-operation system of Boolean fractions—conditional events—than by the standard representation using Hilbert Space. After the requirements of quantum mechanics and the properties of conditional event algebra are introduced, the quantum concepts of orthogonality, completeness, simultaneous verifiability, logical operations, and deductions are expressed in terms of conditional events thereby demonstrating the adequacy and efficacy of this formulation. Since conditional event algebra is nearly (...)

    The Role of Observables and Non-Observables in Chemistry: A Critique of Chemical Language. [REVIEW]Shant Shahbazian & Mansour Zahedi - 2006 - Foundations of Chemistry 8 (1):37-52.
    In this paper, aspects of observable and non-observable based models are discussed. A survey of recent literature was done to show how using non-observable-based language carelessly may cause disagreement, even in professional research programs and incorrect assertions, even in prestigious journals. The relation between physical measurements and observables is discussed and it is shown that, in contrast to general belief, this relation may be complicated and not always straightforward. The decomposition of the system into basic subsystems (physical (...)

  35. A Model of the Quantum-Classical and Mind-Brain Connections, and of the Role of The Quantum Zeno Effect in the Physical Implementation of Conscious Intent.Henry P. Stapp - unknown
    A simple exactly solvable model is given of the dynamical coupling between a person’s classically described perceptions and that person’s quantum mechanically described brain. The model is based jointly upon von Neumann’s theory of measurements and the empirical findings of close connections between conscious intentions and synchronous oscillations in well separated parts of the brain. A quantum-Zeno-effect-based mechanism is described that allows conscious intentions to influence brain activity in a functionally appropriate way. The robustness of this mechanism in the (...)

    This is the second, mathematically more detailed part of a paper consisting of two articles, the first having appeared in the immediately preceding issue of this Journal. It shows that a measurement converts a pure case into a mixture with reducible probabilities. The measurement as such permits no inference whatever as to the state of the physical system subjected to measurement after the measurement has been performed. But because the probabilities after the act are classical and therefore reducible, it (...)

    Everettian Quantum Mechanics and Physical Probability: Against the Principle of “State Supervenience”.Lina Jansson - 2016 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 53:45-53.
    Everettian quantum mechanics faces the challenge of how to make sense of probability and probabilistic reasoning in a setting where there is typically no unique outcome of measurements. Wallace has built on a proof by Deutsch to argue that a notion of probability can be recovered in the many worlds setting. In particular, Wallace argues that a rational agent has to assign probabilities in accordance with the Born rule. This argument relies on a rationality constraint that Wallace calls state (...)

    Retroactive Effects From Measurements.C. W. Rietdijk - 1987 - Foundations of Physics 17 (3):297-311.
    We consider several thought and practical experiments, and variations thereof, from which the existence can be inferred of retroactive effects on the assumptions of conservation of linear and angular momentum and of realism defined in a wide sense. Such conclusion is made less counterintuitive by research into the proper physical background of the relativistic length contraction of a moving arrow, viz. the fact that the universe is four-dimensional indeed. In one of the experiments considered, the evidence of retroactivity is (...)

    Energy-Time Uncertainty Relations in Quantum Measurements.Takayuki Miyadera - 2016 - Foundations of Physics 46 (11):1522-1550.
    Quantum measurement is a physical process. A system and an apparatus interact for a certain time period, and during this interaction, information about an observable is transferred from the system to the apparatus. In this study, we quantify the energy fluctuation of the quantum apparatus required for this physical process to occur autonomously. We first examine the so-called standard model of measurement, which is free from any non-trivial energy–time uncertainty relation, to find that it needs an external system (...)

    A Physical Approach to Tsirelson's Problem.M. Navascués, T. Cooney, D. Pérez-García & N. Villanueva - 2012 - Foundations of Physics 42 (8):985-995.
    Tsirelson’s problem deals with how to model separate measurements in quantum mechanics. In addition to its theoretical importance, the resolution of Tsirelson’s problem could have great consequences for device independent quantum key distribution and certified randomness. Unfortunately, understanding present literature on the subject requires a heavy mathematical background. In this paper, we introduce quansality, a new theoretical concept that allows to reinterpret Tsirelson’s problem from a foundational point of view. Using quansality as a guide, we recover all known results (...)

    The application of the conceptual analysis (CA) method outlined in Part I is illustrated on the example of quantum mechanics. In Part II, we deduce the complete-lattice structure in quantum mechanics from postulates specifying the idealizations that are accepted in the theory. The idealized abstract concepts are introduced by means of a topological extension of the basic structure (obtained in Part I) in accord with the “approximation principle”; the relevant topologies are not arbitrarily chosen; they are fixed by the choice (...)

    The Physical Rationale for Special Relativity.Arthur E. Ruark - 1975 - Foundations of Physics 5 (1):21-36.
    The structure of the Lorentz transformation depends intimately on the conventional operations for measurement of lengths (L) and time intervals (T). The prescription for length measurement leads to justifiable utilization of Euclidean geometry over finite values of the coordinates. Then T-values can be regarded as ratios of length measurements within a suitably defined clock. In certain cases the synchronization process should be supplemented by measurements providing position certification. The Lorentz transformation emerges from three specific symmetry statements, assured by (...)

    Charge Conservation, Klein's Paradox and the Concept of Paulions in the Dirac Electron Theory.Y. V. Kononets - 2010 - Foundations of Physics 40 (5):545-572.
    An algebraic block-diagonalization of the Dirac Hamiltonian in a time-independent external field reveals a charge-index conservation law which forbids the physical phenomena of the Klein paradox type and guarantees a single-particle nature of the Dirac equation in strong external fields. Simultaneously, the method defines simpler quantum-mechanical objects—paulions and antipaulions, whose 2-component wave functions determine the Dirac electron states through exact operator relations. Based on algebraic symmetry, the presented theory leads to a new understanding of the Dirac equation physics, including (...)

    Evidence for the Epistemic View of Quantum States: A Toy Theory.Robert W. Spekkens - 2007 - Physical Review A 75:032110.
    We present a toy theory that is based on a simple principle: the number of questions about the physical state of a system that are answered must always be equal to the number that are unanswered in a state of maximal knowledge. Many quantum phenomena are found to have analogues within this toy theory. These include the noncommutativity of measurements, interference, the multiplicity of convex decompositions of a mixed state, the impossibility of discriminating nonorthogonal states, the impossibility of (...)

    In this paper we give a full account of the work of William Thomson on absolute temperature, which to this day provides the theoretical underpinnings for the most rigorous measurements of temperature. When Thomson fashioned his concepts of ‘absolute’ temperature, his main concern was to make the definition of temperature independent of the properties of particular thermometric substances . He tried out a succession of definitions based on the thermodynamics of ideal heat engines; most notably, in 1854 he gave (...)

  46. Derived Measurement, Dimensions, and Dimensional Analysis.Robert L. Causey - 1969 - Philosophy of Science 36 (3):252-270.
    This paper presents a representational theory of derived physical measurements. The theory proceeds from a formal definition of a class of similar systems. It is shown that such a class of systems possesses a natural proportionality structure. A derived measure of a class of systems is defined to be a proportionality-preserving representation whose values are n-tuples of positive real numbers. Therefore, the derived measures are measures of entire physical systems. The theory provides an interpretation of the dimensional (...)

    Intensive and Extensive Quantities.Zee Perry - manuscript
    Quantities are properties and relations which exhibit "quantitative structure". For physical quantities, this structure can impact the non-quantitative world in different ways. In this paper I introduce and motivate a novel distinction between quantities based on the way their quantitative structure constrains the possible mereological structure of their instances. Specifically, I identify a category of “properly extensive” quantities, which are a proper sub-class of the additive or extensive quantities. I present and motivate this distinction using two case studies of (...)

    How to Compare Color Sensations in Different Brains.Werner Backhaus - 1999 - Behavioral and Brain Sciences 22 (6):944-945.
    The qualitative and quantitative properties of color sensations and neuronal color coding are discussed in relation to physiological color exchanges and their evolutionary constraints. Based on the identity mind/matter thesis, additional physical measurements on color sensations are described that will allow us, at least in principle, to compare the qualitative properties of color sensations in different brains.

    Origin and Resolution of Theory-Choice Situations in Modern Theory of Gravity.Rinat M. Nugayev - 1987 - Methodology and Science 20 (4):177-197.
    A methodological model of origin and settlement of theory-choice situations (previously tried on the theories of Einstein and Lorentz in electrodynamics) is applied to modern Theory of Gravity. The process of origin and growth of empirically-equivalent relativistic theories of gravitation is theoretically reproduced. It is argued that all of them are proposed within the two rival research programmes – (1) metric (A. Einstein et al.) and (2) nonmetric (H. Poincare et al.). Each programme aims at elimination of the cross-contradiction between (...)

    On Measurement and Irreversible Processes.Gunnar Sperber - 1974 - Foundations of Physics 4 (2):163-179.
    The nature of physical measurements performed on microscopic systems is discussed, and it is suggested that the procedures which are conventionally referred to as “measurements” fall into at least three different categories. The connection between observation processes and irreversible processes is stressed. The customary quantum mechanical treatment of irreversible processes is discussed, and its deficiencies from the philosophical point of view are criticized. The standpoint that quantum mechanics should not be considered as a basic philosophical system but (...)
