    Electromagnetic and Gravitational Pictures of the World.Sergey G. Fedosin - 2007 - Apeiron 14 (4):385-413.
    The review of the theory of electromagnetic field together with the special and general theories of relativity has been made. The similar theory of gravitation has been presented which has the property of Lorentz-invariancy in its own representation in which the information is transferred at the speed of propagation of the gravitational field. Generalization of the specified gravitation theory on noninertial reference systems has been made with the help of the mathematical apparatus of the general relativity. It allows to avoid (...)

    When Fields Are Not Degrees of Freedom.Vera Hartenstein & Mario Hubert - forthcoming - British Journal for the Philosophy of Science.
    We show that in the Maxwell–Lorentz theory of classical electrodynamics most initial values for fields and particles lead to an ill-defined dynamics, as they exhibit singularities or discontinuities along light-cones. This phenomenon suggests that the Maxwell equations and the Lorentz force law ought rather to be read as a system of delay differential equations, that is, differential equations that relate a function and its derivatives at different times. This mathematical reformulation, however, leads to physical and philosophical consequences for the ontological (...)

    Chance in Science: The Discovery of Electromagnetism by H.C. Oersted.Nahum Kipnis - 2005 - Science and Education: Academic Journal of Ushynsky University 14 (1):1-28.
    Ignoring therole of chance in science distorts the nature of the scientific process. Teachers can address this issue by means of several in-depth historical case studies, such as the discovery of electromagnetism by Oersted. Oersted was led to his lecture experiment by logic (two new hypotheses), but its success from the first trial was largely due to chance. Reproducing Oersted's experiment in the classroom complements the story by atlowing students to see for themselves the role of some accidental factors, such (...)

    This paper examines J. C. Maxwell’s electromagnetic field as the key idea for the development of A. N. Whitehead's event ontology. Whitehead viewed Maxwell's electromagnetism as the most revolutionary development of modern physics whereby events rather than substances become the basic units of reality.

    Fundamental Physics and the Fine-Structure Constant.Michael A. Sherbon - 2017 - International Journal of Physical Research 5 (2):46-48.
    From the exponential function of Euler’s equation to the geometry of a fundamental form, a calculation of the fine-structure constant and its relationship to the proton-electron mass ratio is given. Equations are found for the fundamental constants of the four forces of nature: electromagnetism, the weak force, the strong force and the force of gravitation. Symmetry principles are then associated with traditional physical measures.

    The aim of this paper is to illustrate four properties of the non-relativistic limits of relativistic theories: that a massless relativistic field may have a meaningful non-relativistic limt, that a relativistic field may have more than one non-relativistic limit, that coupled relativistic systems may be "more relativistic" than their uncoupled counterparts, and that the properties of the non-relativistic limit of a dynamical equation may differ from those obtained when the limiting equation is based directly on exact Galilean kinematics. These properties (...)

    On Understanding: Maxwell on the Methods of Illustration and Scientific Metaphor.Jordi Cat - 2001 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 32 (3):395-441.
    In this paper I examine the notion and role of metaphors and illustrations in Maxwell's works in exact science as a pathway into a broader and richer philosophical conception of a scientist and scientific practice. While some of these notions and methods are still at work in current scientific research-from economics and biology to quantum computation and quantum field theory-, here I have chosen to attest to their entrenchment and complexity in actual science by attempting to make some conceptual sense (...)

    The place of Heinrich Hertz’s The principles of mechanics in the history of the philosophy of science is disputed. Here I critically assess positivist interpretations, concluding that they are inadequate.There is a group of commentators who seek to align Hertz with positivism, or with specific positivists such as Ernst Mach, who were enormously influential at the time. Max Jammer is prominent among this group, the most recent member of which is Joseph Kockelmans. I begin by discussing what Hertz and Mach (...)

    Maxwell's Demon.Meir Hemmo & Orly Shenker - 2006 - Journal of Philosophy 107 (8):389-411.
    This paper proves that Maxwell's Demon is compatible with classical mechanics. In particular it shows how the cycle of operation - including measurement and erasure - can be carried out with no entropy cost, contrary to the Landauer-Bennett thesis (according to which memory erasure costs kln2 of entropy increase per bit). The Landauer-Bennet thesis is thus proven to be mistaken.

    Those looking for holism in contemporary physics have focused their attention primarily on quantum entanglement. But some gauge theories arguably also manifest the related phenomenon of nonseparability. While the argument is strong for the classical gauge theory describing electromagnetic interactions with quantum “particles”, it fails in the case of general relativity even though that theory may also be formulated in terms of a connection on a principal fiber bundle.

    The Replication of Hertz's Cathode Ray Experiments.James Mattingly - 2001 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 32 (1):53-75.
    I reappraise in detail Hertz's cathode ray experiments. I show that, contrary to Buchwald 's evaluation, the core experiment establishing the electrostatic properties of the rays was successfully replicated by Perrin and Thomson. Buchwald 's discussion of 'current purification' is shown to be a red herring. My investigation of the origin of Buchwald 's misinterpretation of this episode reveals that he was led astray by a focus on what Hertz 'could do'-his experimental resources. I argue that one should focus instead (...)

    Plasma Brain Dynamics (PBD): A Mechanism for EEG Waves Under Human Consciousness.Z. G. ma - 2017 - Cosmos and History 13 (2):185-203.
    EEG signals are records of nonlinear solitary waves in human brains. The waves have several types (e.g., α, β, γ, θ, δ) in response to different levels of consciousness. They are classified into two groups: Group-1 consists of complex storm-like waves (α, β, and γ); Group-2 is composed of simple quasilinear waves (θ and δ). In order to elucidate the mechanism of EEG wave formation and propagation, this paper extends the Vlasov-Maxwell equations of Plasma Brain Dynamics (PBD) to a set (...)

Nature uses the olfactory fields, the acoustic fields, the electromagnetic fields and quantum-vacuum fields. Fields with their ability to comprehend the whole organism are the natural basis of a global interaction between organisms and of collective consciousness. Evidences are presented that electromagnetic potential fields mediate the collective field of (...)

    Laws and Initial Conditions.Mathias Frisch - 2004 - Philosophy of Science 71 (5):696-706.
    I discuss two case studies from classical electrodynamics challenging the distinction between laws that delineate physically possible words and initial conditions. First, for many reasonable initial conditions there exist no global solutions to the Maxwell‐Lorentz equations for continuous charge distributions. Second, in deriving an equation of motion for a charged point particle one needs to invoke an asymptotic condition that seems to express a physically contingent fact even though it is mathematically necessary for the derivation.

    Einstein's theories of special and general relativity are unanimously praised by scientists for their extraordinary beauty to the extent that some consider the latter to be the most beautiful theory in physics. The grounds for these assertions are assessed here and it is concluded that the beauty of Einstein's theories can be attributed to two of their aspects. The first is that they incorporate all possible ingredients that constitute the beauty of theories: simplicity, symmetry, invariance, unification, etc. The second concerns (...)

    Attemts to explain causal paradoxes of Quantum Mechanics (QM) have tried to solve the problems within the framework of Quantum Electrodynamics (QED). We will show, that this is impossible. The original theory of QED by Dirac (Proc Roy Soc A117:610, 1928) formulated in its preamble four preliminary requirements that the new theory should meet. The first of these requirements was that the theory must be causal. Causality is not to be derived as a consequence of the theory since it was (...)

    Connecting Gravity with Electricity.John G. Cramer - unknown
    Gravity is an extremely weak force . Consider two spheres that are close together, each with one kilogram of mass and one coulomb of electric charge, i.e., one unit each of charge and mass in Standard International Units. There will be electrical repulsion pushing them apart and gravitational attraction pulling them together, but which is bigger? It’s no contest: the electric force between these spheres is 1.35 x 1020times stronger than the gravitational force. But perhaps this difference is so large (...)

    Theoretical Equivalence as Interpretative Equivalence.Kevin Coffey - 2014 - British Journal for the Philosophy of Science 65 (4):821-844.
    The problem of theoretical equivalence is traditionally understood as the problem of specifying when superficially dissimilar accounts of the world are reformulations of a single underlying theory. One important strategy for answering this question has been to appeal to formal relations between theoretical structures. This article presents two reasons to think that such an approach will be unsuccessful and suggests an alternative account of theoretical equivalence, based on the notion of interpretive equivalence, in which the problem is merely an instance (...)

We review the foundations of classical electromagnetism based on charge and magnetic flux conservation, the Lorentz force and the constitutive relations. These relations introduce the conformal part of the metric and allow the study of electrodynamics for (...)

    The fact that the same equations or mathematical models reappear in the descriptions of what are otherwise disparate physical systems can be seen as yet another manifestation of Wigner's “unreasonable effectiveness of mathematics.” James Clerk Maxwell famously exploited such formal similarities in what he called the “method of physical analogy.” Both Maxwell and Hermann von Helmholtz appealed to the physical analogies between electromagnetism and hydrodynamics in their development of these theories. I argue that a closer historical examination of the different (...)
