    Electromagnetic Waves.Sydney Ernest Grimm - manuscript
    In the past the particle-wave duality of electromagnetic waves dominated the discussions about the nature of light. No consensus had been reached amongst physicists and philosophers of physics concerning which interpretation represents reality best. However, two different concepts for the same phenomenon doesn’t really convince about the reliability of the conceptual framework. So what is wrong?

    The Construction of Electromagnetism.Mario Natiello & H. G. Solari - manuscript
    Abstract We examine the construction of electromagnetism in its current form, and in an alternative form, from a point of view that combines a minimal realism with strict rational demands. We begin by discussing the requests of reason when constructing a theory and next, we follow the historical development as presented in the record of original publications, the underlying epistemology (often explained by the authors) and the mathematical constructions. The historical construction develops along socio-political disputes (mainly, the reunification of Germany (...)

    Growing Evidence That Perceptual Qualia Are Neuroelectrical Not Computational.Mostyn W. Jones - 2019 - Journal of Consciousness Studies 26 (5-6):89-116.
    Computational neuroscience attributes coloured areas and other perceptual qualia to calculations that are realizable in multiple cellular forms. This faces serious issues in explaining how the various qualia arise and how they bind to form overall perceptions. Qualia may instead be neuroelectrical. Growing evidence indicates that perceptions correlate with neuroelectrical activity spotted by locally activated EEGs, the different qualia correlate with the different electrochemistries of unique detector cells, a unified neural-electromagnetic field binds this activity to form overall perceptions, and this (...)

    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:axy060.
    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 (...)

    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.

    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 (...)

    General Classical Electrodynamics.van Vlaenderen Koen - 2016 - Universal Journal of Physics and Application 10 (4):128-140.
    Maxwell’s Classical Electrodynamics (MCED) suffers several inconsistencies: (1) the Lorentz force law of MCED violates Newton’s Third Law of Motion (N3LM) in case of stationary and divergent or convergent current distributions; (2) the general Jefimenko electric field solution of MCED shows two longitudinal far fields that are not waves; (3) the ratio of the electrodynamic energy-momentum of a charged sphere in uniform motion has an incorrect factor of 4/3. A consistent General Classical Electrodynamics (GCED) is presented that is based on (...)

    Maxwell, Helmholtz, and the Unreasonable Effectiveness of the Method of Physical Analogy.Alisa Bokulich - 2015 - Studies in History and Philosophy of Science Part A 50:28-37.
    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 (...)

    On the Angular Momentum of a System of Quantum Particles.Oscar Chavoya Aceves - manuscript
    The properties of angular momentum and its connection to magnetic momentum are explored, based on a reconsideration of the Stern-Gerlach experiment and gauge invariance. A possible way to solve the so called spin crisis is proposed. The separation of angular momentum of a quan- tum system of particles into orbital angular momentum plus intrinsic angular momentum is reconsidered, within the limits of the Schrodinger theory. A proof is given that, for systems of more than two particles, un- less all of (...)

    The Conscious Electromagnetic Information Field Theory: The Hard Problem Made Easy?J. McFadden - 2002 - Journal of Consciousness Studies 9 (8):45-60.
    In the April 2002 edition of JCS I outlined the conscious electromagnetic information field theory, claiming that consciousness is that component of the brain's electromagnetic field that is downloaded to motor neurons and is thereby capable of communicating its informational content to the outside world. In this paper I demonstrate that the theory is robust to criticisms. I further explore implications of the theory particularly as regards the relationship between electromagnetic fields, information, the phenomenology of consciousness and the meaning of (...)

    The Methodological Problems of Theory Unification (in the context of Maxwell's fusion of optics and electrodynamics).Rinat M. Nugayev - 2016 - Philosophy of Science and Technology (Moscow) 21 (2).
    It is discerned what light can bring the recent historical reconstructions of maxwellian optics and electromagnetism unification on the following philosophical/methodological questions. I. Why should one believe that Nature is ultimately simple and that unified theories are more likely to be true? II. What does it mean to say that a theory is unified? III. Why theory unification should be an epistemic virtue? To answer the questions posed genesis and development of Maxwellian electrodynamics are elucidated. It is enunciated that the (...)

    On Modern Science, Human Cognition, and Cultural Diversity.Alfred Gierer - 2000 - In Preprint series, Max Planck Institute for the History of Science. MPI for the History of Science. pp. Preprint 137, 1-16.
    The development of modern science has depended strongly on specific features of the cultures involved; however, its results are widely and trans-culturally accepted and applied. The science and technology of electricity provides a particularly interesting example. It emerged as a specific product of post-Renaissance Europe, rooted in the Greek philosophical tradition that encourages explanations of nature in theoretical terms. It did not evolve in China presumably because such encouragement was missing. The trans-cultural acceptance of modern science and technology is postulated (...)

    The book addresses the question of what are the routes and mechanisms of the theory-change process in science at the level when the change involves the calling in question of a mature theory, i.e. one which has been accepted as accounting very well for a large range of experimental phenomenon.

    Classical Electrodynamics in Agreement with Newton’s Third Law of Motion.Koenraad Johan van Vlaenderen - manuscript
    The force law of Maxwell’s classical electrodynamics does not agree with Newton’s third law of motion (N3LM), in case of open circuit magnetostatics. Initially, a generalized magnetostatics theory is presented that includes two additional physical fields B_Φ and B_l, defined by scalar functions. The scalar magnetic field B_l mediates a longitudinal Ampère force that balances the transverse Ampère force (aka the magnetic field force), such that the sum of the two forces agrees with N3LM for all stationary current distributions. Secondary (...)

    Maxwellian Scientific Revolution: Reconciliation of Research Programmes of Young-Fresnel,Ampere-Weber and Faraday.Rinat M. Nugayev (ed.) - 2013 - Kazan University Press.
    Maxwellian electrodynamics genesis is considered in the light of the author’s theory change model previously tried on the Copernican and the Einstein revolutions. It is shown that in the case considered a genuine new theory is constructed as a result of the old pre-maxwellian programmes reconciliation: the electrodynamics of Ampere-Weber, the wave theory of Fresnel and Young and Faraday’s programme. The “neutral language” constructed for the comparison of the consequences of the theories from these programmes consisted in the language of (...)

    From the Relative Existence of Electromagnetic Field to its Connection with the Gravitational Field.Mavriche Adrian - 2012 - NON.
    The present document starts from the relative existence of the electromagnetic field, reaching through mental experiments to its connection with the gravitational field, without the necessity to resort to other space - time dimensions or supplementary "exotic" particles. The final conclusion is that the field "electro-gravitational" and electromagnetic field with accelerated source are two different manifestations of the same single field dynamic. Whilst demonstrating why there are light sources with "flee" towards the red or blue of the light spectrum.

    Generalizing "Charge Without Charge" to Obtain Classical Analogs of Short-Range Interactions.Mark Sharlow - manuscript
    Several decades ago, Wheeler and Misner presented a model of electric charge based on the topological trapping of electric field lines in wormholes. In this paper, which does not argue for or against the "charge without charge" concept, I describe some generalizations of this model which might serve as topological analogs of color charges and electroweak charges.

    Maxwell's Paradox: The Metaphysics of Classical Electrodynamics and its Time Reversal Invariance.Valia Allori - 2015 - Analytica: an electronic, open-access journal for philosophy of science 1:1-19.
    In this paper, I argue that the recent discussion on the time - reversal invariance of classical electrodynamics (see (Albert 2000: ch.1), (Arntzenius 2004), (Earman 2002), (Malament 2004),(Horwich 1987: ch.3)) can be best understood assuming that the disagreement among the various authors is actually a disagreement about the metaphysics of classical electrodynamics. If so, the controversy will not be resolved until we have established which alternative is the most natural. It turns out that we have a paradox, namely that the (...)

    Maxwellian Scientific Revolution: A Case Study in Kantian Epistemology.Rinat M. Nugayev - 2014 - Logos and Episteme 5 (2):183-207.
    It is exhibited that maxwellian electrodynamics grew out of the old pre-maxwellian programmes reconciliation: the electrodynamics of Ampere-Weber, the wave theory of Young-Fresnel and Faraday’s scientific research programme. The programmes’ meeting led to construction of the whole hierarchy of theoretical objects starting from the genuine crossbreeds (the displacement current) and up to usual mongrels. After the displacement current invention the interpenetration of the pre-maxwellian programmes began that marked the beginning of theoretical schemes of optics and electromagnetism real unification. Maxwell’s programme (...)

    Is the World Made of Loops?Alexander Afriat - manuscript
    In discussions of the Aharonov-Bohm effect, Healey and Lyre have attributed reality to loops $\sigma_0$ (or hoops $[\sigma_0]$), since the electromagnetic potential $A$ is currently unmeasurable and can therefore be transformed. I argue that $[A]=[A+d\lambda]_{\lambda}$ and the hoop $[\sigma_0]$ are related by a meaningful duality, so that however one feels about $[A]$ (or any potential $A\in[A]$), it is no worse than $[\sigma_0]$ (or any loop $\sigma_0\in[\sigma_0]$): no ontological firmness is gained by retreating to the loops, which are just as flimsy (...)
