    4. Interpreting Planck scale gravitational orbitals via atomic orbital transitions.Malcolm Macleod - manuscript
    An orbital simulation program is described that uses a geometrical approach to emulate gravitational and atomic orbits at the Planck scale. The gravitational orbital approach divides orbiting objects into multiples of Planck mass points to form an n-body complex of discrete point-to-point orbital pairs between the objects. Each orbital pair rotates 1 Planck length per unit of Planck time in a continuous loop such that when mapped over time gravitational orbits emerge. However 1 point may contain 10^{20} or more individual (...)

  2. Fundamental Nature of the Fine-Structure Constant.Michael A. Sherbon - 2014 - International Journal of Physical Research 2 (1):1-9.
    Arnold Sommerfeld introduced the fine-structure constant that determines the strength of the electromagnetic interaction. Following Sommerfeld, Wolfgang Pauli left several clues to calculating the fine-structure constant with his research on Johannes Kepler's view of nature and Pythagorean geometry. The Laplace limit of Kepler's equation in classical mechanics, the Bohr-Sommerfeld model of the hydrogen atom and Julian Schwinger's research enable a calculation of the electron magnetic moment anomaly. Considerations of fundamental lengths such as the charge radius of the proton (...)

  3. Bohr as a Phenomenological Realist.Towfic Shomar - 2008 - Journal for General Philosophy of Science / Zeitschrift für Allgemeine Wissenschaftstheorie 39 (2):321-349.
    There is confusion among scholars of Bohr as to whether he should be categorized as an instrumentalist (see Faye 1991) or a realist (see Folse 1985). I argue that Bohr is a realist, and that the confusion is due to the fact that he holds a very special view of realism, which did not coincide with the philosophers’ views. His approach was sometimes labelled instrumentalist and other times realist, because he was an instrumentalist on the theoretical level, but (...)

  4. Bohr’s Relational Holism and the classical-quantum Interaction.Mauro Dorato - 2016
    In this paper I present and critically discuss the main strategies that Bohr used and could have used to fend off the charge that his interpretation does not provide a clear-cut distinction between the classical and the quantum domain. In particular, in the first part of the paper I reassess the main arguments used by Bohr to advocate the indispensability of a classical framework to refer to quantum phenomena. In this respect, by using a distinction coming from an (...)

  5. Bohr on EPR, the Quantum Postulate, Determinism, and Contextuality.Zachary Hall - 2024 - Foundations of Physics 54 (3):1-35.
    The famous EPR article of 1935 challenged the completeness of quantum mechanics and spurred decades of theoretical and experimental research into the foundations of quantum theory. A crowning achievement of this research is the demonstration that nature cannot in general consist in noncontextual pre-measurement properties that uniquely determine possible measurement outcomes, through experimental violations of Bell inequalities and Kochen-Specker theorems. In this article, I reconstruct an argument from Niels Bohr’s writings that the reality of the Einstein-Planck-de Broglie relations alone (...)

  6. Barad, Bohr, and quantum mechanics.Jan Faye & Rasmus Jaksland - 2021 - Synthese 199:8231-8255.
    The last decade has seen an increasing number of references to quantum mechanics in the humanities and social sciences. This development has in particular been driven by Karen Barad’s agential realism: a theoretical framework that, based on Niels Bohr’s interpretation of quantum mechanics, aims to inform social theorizing. In dealing with notions such as agency, power, and embodiment as well as the relation between the material and the discursive level, the influence of agential realism in fields such as feminist (...)

  8. Can we close the Bohr-Einstein quantum debate.Marian Kupczynski - 2017 - Philosophical Transactions of the Royal Society A 375:20160392..
    Recent experiments allowed concluding that Bell-type inequalities are indeed violated thus it is important to understand what it means and how can we explain the existence of strong correlations between outcomes of distant measurements. Do we have to announce that: Einstein was wrong, Nature is nonlocal and nonlocal correlations are produced due to the quantum magic and emerge, somehow, from outside space-time? Fortunately such conclusions are unfounded because if supplementary parameters describing measuring instruments are correctly incorporated in a theoretical model (...)

I won't have space to make the case adequately here, but my own view is that we have not yet fully digested the message brought to us by Bohr's "Copenhagen Interpretation" of Quantum Mechanics, and (...)

  10. The Bohr and Einstein debate - Copenhagen Interpretation challenged.Rochelle Marianne Forrester - unknown
    The Bohr Einstein debate on the meaning of quantum physics involved Einstein inventing a series of thought experiments to challenge the Copenhagen Interpretation of quantum physics. Einstein disliked many aspects of the Copenhagen Interpretation especially its idea of an observer dependent universe. Bohr was able to answer all Einstein’s objections to the Copenhagen Interpretation and so is usually considered as winning the debate. However the debate has continued into the present time as many scientists have been unable to (...)

    The article formulates and substantiates the philosophical epistemological principle, which generalizes the principle of complementarity of Bohr to all phenomena of reality. The general complementarity principle is formulated as follows: the rational side of reality and its cognition and its associated irrational side of reality and its cognition are complementary to each other. The general principle of complementarity allows one to search for phenomena of duality in various fields, grouping them according to rational and irrational signs.

    Niels Bohr acuñó la idea de complementariedad porque se encontraba, a causa del postulado cuántico, ante representaciones heterogéneas que no accedían a síntesis final. La Modernidad se caracterizó por su razón totalizante. En la actualidad, la crisis de la Modernidad nos impele a dar paso a la diferencia, que expresa la plurivocidad de la experiencia humana. La complementariedad se presenta como un paradigma de pensamiento adecuado para dar respuesta, sin perder los logros de la Modernidad, a las demandas posmodernas. (...)

    Kierkegaard's Either-Or is a book about the choice between aesthetic, ethical, and religious approaches to life. I show that Either-Or also contains a proposal for philosophy of science, and in particular, about the ideal epistemic state for human beings. Whereas the Cartesian-Hegelian tradition conceived of the ideal state as one of detached deliberation -- i.e. "seeing the world as it is in itself" -- Kierkegaard envisions the ideal state as the achievement of equilibrium between the "spectator" and "actor" aspects of (...)

But two major problematics remain. The problem of integration concerns the surplus of possibilities for integration; different tools produce different assessments. The problem of implementation concerns the barrier between assessment and transformation; assessments do not lead to the expected changes in practice.

The problem is that in the XX century the physical science completely changed (...)

    It is not so long ago that philosophers and scientists thought of science as an objective and value-free enterprise. But since the heyday of positivism, it has become obvious that values, norms, and standards have an indispensable role to play in science. You may even say that these values are the real issues of the philosophy of science. Whatever they are, these values constrain science at an ontological, a cognitive, a methodological, and a semantic level for the purpose of making (...)

His attempt gave birth to a pretty vast literature that links Jung’s synchronicity to Bohr’s complementarity. I will show that such (...)

    Dualities are a pervasive phenomenon in contemporary physics, in which two physical theories are empirically equivalent, yet prima facie make different ontological claims about the world (potentially very different claims—differing in e.g. the number and radius of dimensions of the universe). Dualities thus present a particular instantiation of the well-known notion of underdetermination of theory by evidence. Many different philosophical proposals have been made for how such putative underdetermination might be resolved—this continues to be a programme of active research.

    Are thought experiments nothing but arguments? I argue that it is not possible to make sense of the historical trajectory of certain thought experiments if one takes them to be arguments. Einstein and Bohr disagreed about the outcome of the clock-in-the-box thought experiment, and so they reconstructed it using different arguments. This is to be expected whenever scientists disagree about a thought experiment's outcome. Since any such episode consists of two arguments but just one thought experiment, the thought experiment (...)

Having made sure that the distinction is conceptually sound, I then analyze the plausibility of the widespread, monistic (...)

In other words, no sane person should advocate extreme realism or antirealism about the quantum state. And if we focus on (...)

    The ontology of Local Quantum Physics, Rudolf Haag’s framework for relativistic quantum theory, is reviewed and discussed. It is one of spatiotemporally localized events and unlocalized causal intermediaries, including the elementary particles, which come progressively into existence in accordance with a fundamental arrow of time. Haag’s conception of quantum theory is distinguished from others in which events are also central, especially those of Niels Bohr and John Wheeler, with which it has been compared.

The foramen is important both morphologically and clinically. -/- Methods: A total of 414 adult human dry bones were investigated in this study to identify topographic and morphological features of nutrient foramina in the scapula, clavicle, humerus, radius and (...)

  45. On the fundamental role of massless form of matter in physics. Quantum gravity.Alexander Klimets - 2017 - FIZIKA B (Zagreb) 9:23-42.
    In the article, with the help of various models, the thesis on the fundamental nature of the field form of matter in physics is considered. In the first chapter a model of special relativity is constructed, on the basis of which the priority of the massless form of matter is revealed. In the second chapter, a field model of inert and heavy mass is constructed and on this basis the mechanism of inertia and gravity of weighty bodies is revealed. In (...)

  46. On momentum operators given by Killing vectors whose integral curves are geodesics.Thomas Schürmann - 2022 - Physics 4 (4): 1440-1452.
    We consider momentum operators on intrinsically curved manifolds. Given that the momentum operators are Killing vector fields whose integral curves are geodesics, it is shown that the corresponding manifold is either flat, or otherwise of compact type with positive constant sectional curvature and dimension equal to 1, 3 or 7. Explicit representations of momentum operators and the associated Casimir element will be discussed for the 3-sphere. It will be verified that the structure constants of the underlying Lie algebra are proportional (...)

    A discussion of a geometric shape that became a symbol known as mandorla or vesica piscis, starting from a Pythagorean point of view.Amelia Carolina Sparavigna - manuscript
    Here we propose a discussion about the "mandorla" or "vesica piscis". It is a type of 2-dimensional lens, that is, a geometric shape formed by the intersection of two circles with the same radius, intersecting in such a way that the centre of each circle lies on the perimeter of the other. The aim of the discussion is that of understanding when such a geometric shape became a symbol and when this symbol received a specific name. We will find (...)

  48. No Paradox in Wave–Particle Duality.Andrew Knight - 2020 - Foundations of Physics 50 (11):1723-1727.
    The assertion that an experiment by Afshar et al. demonstrates violation of Bohr’s Principle of Complementarity is based on the faulty assumption that which-way information in a double-slit interference experiment can be retroactively determined from a future measurement.

  49. Is the quantum world composed of propensitons?Nicholas Maxwell - 2010 - In Mauricio Suárez (ed.), Probabilities, Causes and Propensities in Physics. New York: Springer. pp. 221-243.
    In this paper I outline my propensiton version of quantum theory (PQT). PQT is a fully micro-realistic version of quantum theory that provides us with a very natural possible solution to the fundamental wave/particle problem, and is free of the severe defects of orthodox quantum theory (OQT) as a result. PQT makes sense of the quantum world. PQT recovers all the empirical success of OQT and is, furthermore, empirically testable (although not as yet tested). I argue that Einstein almost put (...)

  50. How the Laws of Physics Can be Confronted with Experience.Rinat M. Nugayev - 1992 - Theoria Et Historia Scientiarum:24-36.
    Nancy Cartwright’s arguments in favor of the phenomenological laws and against the fundamental ones are discussed. I support and strengthen her criticism of the standard covering-law account but I am skeptical in respect to her radical conclusion that the laws of physics lie. Arguments in favor of the opposite stance are based on V.S. Stepin’s analysis of mature theory structure. A mature theory-change model presented here demonstrates how the fundamental laws of physics can be confronted with experience. Its case studies (...)
