    The Energy of a Dynamical Wave-Emitting System in General Relativity.F. I. Cooperstock & S. Tieu - 2003 - Foundations of Physics 33 (7):1033-1059.
    The problem of energy and its localization in general relativity is critically re-examined. The Tolman energy integral for the Eddington spinning rod is analyzed in detail and evaluated apart from a single term. It is shown that a higher order iteration is required to find its value. Details of techniques to solve mathematically challenging problems of motion with powerful computing resources are provided. The next phase of following a system from static to dynamic to final quasi-static state is (...)

  5. Energy Non-conservation in Quantum Mechanics.Sean M. Carroll & Jackie Lodman - 2021 - Foundations of Physics 51 (4):1-15.
    We study the conservation of energy, or lack thereof, when measurements are performed in quantum mechanics. The expectation value of the Hamiltonian of a system changes when wave functions collapse in accordance with the standard textbook treatment of quantum measurement, but one might imagine that the change in energy is compensated by the measuring apparatus or environment. We show that this is not true; the change in the energy of a state after measurement can be arbitrarily (...)

    Do Gravitational Waves Carry Energy? -Critique of a Procrustean Practice.Patrick Dürr - unknown
    We submit that, contrary to the standard view, gravitational waves do not carry energy-momentum. Analysing the four standard arguments on which the standard view rests - viz. the kinetic effects of a GW on a detector, Feynman’s Sticky Bead Argument, an application of Noether’s Theorem and a general perturbative approach – we find none of them to be successful: Pre-relativistic premises underlie each of them – premises that, as we argue, no longer hold in General Relativity. Finally, we outline (...)

    It ain't necessarily so: Gravitational waves and energy transport.Patrick M. Duerr - 2019 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 65:25-40.
    In the following paper, I review and critically assess the four standard routes commonly taken to establish that gravitational waves possess energy-momentum: the increase in kinetic energy a GW confers on a ring of test particles, Bondi/Feynman’s Sticky Bead Argument of a GW heating up a detector, nonlinearities within perturbation theory, taken to reflect the fact that gravity contributes to its own source, and the Noether Theorems, linking symmetries and conserved quantities. Each argument is found to either to (...)

    Unlocking Energy Innovation: How America Can Build a Low-Cost, Low-Carbon Energy System.Richard Keith Lester & David M. Hart - 2011 - MIT Press.
    Energy innovation offers us our best chance to solve the three urgent and interrelated problems of climate change, worldwide insecurity over energy supplies, and rapidly growing energy demand. But if we are to achieve a timely transition to reliable, low-cost, low-carbon energy, the U.S. energy innovation system must be radically overhauled. Unlocking Energy Innovation outlines an up-to-the-minute plan for remaking America's energy innovation system by tapping the country's entrepreneurial strengths and regional diversity in (...)

  10. Yijing and Energy Fields.David Leong - manuscript
    The sequential patterns of the sixty-four hexagrams in the Yijing, variously known as I Ching (the Book of Changes) are structured to embrace the universe of possibilities, scenarios and probabilities. Each hexagram equates to each moment in space-time. With the arrow of time, a string of hexagrams represent a string of moments. A probability curve can be formed from the string of hexagrams. Physicists call this mathematical entity a wave function which is constantly changing and proliferating. A wave (...)

    Energy and Angular Momentum of Systems in General Relativity.F. I. Cooperstock - 2001 - Foundations of Physics 31 (7):1067-1082.
    Stemming from our energy localization hypothesis that energy in general relativity is localized in the regions of the energy-momentum tensor, we had devised a test with the classic Eddington spinning rod. Consistent with the localization hypothesis, we found that the Tolman energy integral did not change in the course of the motion. This implied that gravitational waves do not carry energy in vacuum, bringing into question the demand for the quantization of gravity. Also if information (...)

    Complex energies in relativistic quantum theory.James D. Edmonds - 1974 - Foundations of Physics 4 (4):473-479.
    A new four-component spin-1/2 wave equation for ordinary mass is discussed. It is shown that this equation has a conserved current not easily identified with a transition probability, only pure imaginary energy states, and is covariant. A tachyon-like Klein-Gordon equation is satisfied by this equation, but rest states are explicitly constructed.

    Self-Energy and Action Principle in Relativistic Schrödinger Theory.P. Schust, F. Stary, M. Mattes & M. Sorg - 2005 - Foundations of Physics 35 (6):1043-1105.
    The mathematical framework of Relativistic Schrödinger Theory (RST) is generalized in order to include the self-interactions of the particles as an integral part of the theory (i.e. in a non-perturbative way). The extended theory admits a Lagrangean formulation where the Noether theorems confirm the existence of the conservation laws for charge and energy–momentum which were originally deduced directly from the dynamical equations. The generalized RST dynamics is applied to the case of some heavy helium-like ions, ranging from germanium (Z=32) (...)

    Dark matter and dark energy. Two notions that have troubled cosmologists for a long time. Why? Because they don’t have a “satisfactory” definition, and nobody can identify the “matter” or “forces” that govern them. Currently, we can only deduce the existence of these two notions from the strange movement of the galaxies and the manner they move away from one another, with increasing speed. However, these are not the only mysteries that cosmology cannot yet explain. What happened before the (...)

    Neutrino Oscillations: Entanglement, Energy-Momentum Conservation and QFT. [REVIEW]E. K. Akhmedov & A. Y. Smirnov - 2011 - Foundations of Physics 41 (8):1279-1306.
    We consider several subtle aspects of the theory of neutrino oscillations which have been under discussion recently. We show that the S-matrix formalism of quantum field theory can adequately describe neutrino oscillations if correct physics conditions are imposed. This includes space-time localization of the neutrino production and detection processes. Space-time diagrams are introduced, which characterize this localization and illustrate the coherence issues of neutrino oscillations. We discuss two approaches to calculations of the transition amplitudes, which allow different physics interpretations: (i) (...)

    Energy localization in general relativity: A new hypothesis. [REVIEW]F. I. Cooperstock - 1992 - Foundations of Physics 22 (8):1011-1024.
    A new hypothesis for energy localization in general relativity is introduced which is based upon the fact that the energy-momentum conservation laws are devoid of content in vacuum. The vanishing of pseudotensor components forms the basis of coordinate conditions consistent with the above. The implication is that energy is localized where the energy-momentum tensor is nonvanishing. As a consequence, gravitational waves are not carriers of energy in vacuum. A detailed analysis of a Feynman detector interacting (...)

  17. Quantum Paradoxes, Time, and Derivation of Thermodynamic Law: Opportunities from Change of Energy Paradigm.Helmut Tributsch - 2006 - Journal for General Philosophy of Science / Zeitschrift für Allgemeine Wissenschaftstheorie 37 (2):287-306.
    Well known quantum and time paradoxes, and the difficulty to derive the second law of thermodynamics, are proposed to be the result of our historically grown paradigm for energy: it is just there, the capacity to do work, not directly related to change. When the asymmetric nature of energy is considered, as well as the involvement of energy turnover in any change, so that energy can be understood as fundamentally "dynamic", and time-oriented, these paradoxes and problems (...)

    In response to Cushing it is urged that the vicissitudes of quantum field theory do not press towards a nonrealist attitude towards the theory as strongly as he suggests. A variety of issues which Redhead raises are taken up, including photon localizability, the wave-particle distinction in the classical limit, and the interpretation of quantum statistics, vacuum fluctuations, virtual particles, and creation and annihilation operators. It is urged that quantum field theory harbors an unacknowledged inconsistency connected with the fact that (...)

    Action Quantization, Energy Quantization, and Time Parametrization.Edward R. Floyd - 2017 - Foundations of Physics 47 (3):392-429.
    The additional information within a Hamilton–Jacobi representation of quantum mechanics is extra, in general, to the Schrödinger representation. This additional information specifies the microstate of \ that is incorporated into the quantum reduced action, W. Non-physical solutions of the quantum stationary Hamilton–Jacobi equation for energies that are not Hamiltonian eigenvalues are examined to establish Lipschitz continuity of the quantum reduced action and conjugate momentum. Milne quantization renders the eigenvalue J. Eigenvalues J and E mutually imply each other. Jacobi’s theorem generates (...)

  20. Some Consequences of Zero Point Energy.Bo Lehnert - 2014 - JEMAA 6:319-327.
    Both theory and experiments indicate that the vacuum is not a state of empty space, but is populated by electromagnetic fluctuations at a lowest nonzero level, the Zero Point Energy (ZPE). This debouches into considerable changes of fundamental physics, as shown by a revised quantum electrodynamic theory (RQED) applied to elementary particles, and by a revised ZPE frequency spectrum applied to the expanding universe. The Standard Model based on a vacuum state of empty space is thus replaced by RQED, (...)

    The explicit history of the “hidden variables” problem is well-known and established. The main events of its chronology are traced. An implicit context of that history is suggested. It links the problem with the “conservation of energy conservation” in quantum mechanics. Bohr, Kramers, and Slaters (1924) admitted its violation being due to the “fourth Heisenberg uncertainty”, that of energy in relation to time. Wolfgang Pauli rejected the conjecture and even forecast the existence of a new and unknown then (...)

  22. On geometric objects, the non-existence of a gravitational stress-energy tensor, and the uniqueness of the Einstein field equation.Erik Curiel - 2009 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 66:90-102.
    The question of the existence of gravitational stress-energy in general relativity has exercised investigators in the field since the inception of the theory. Folklore has it that no adequate definition of a localized gravitational stress-energetic quantity can be given. Most arguments to that effect invoke one version or another of the Principle of Equivalence. I argue that not only are such arguments of necessity vague and hand-waving but, worse, are beside the point and do not address the heart of (...)

    A (to our knowledge) novel Generalized Nonlinear Schrödinger equation based on the modifications of Nottale-Cresson’s fractal-scale calculus and resulting from the noncommutativity of the phase space coordinates is explicitly derived. The modifications to the ground state energy of a harmonic oscillator yields the observed value of the vacuum energy density. In the concluding remarks we discuss how nonlinear and nonlocal QM wave equations arise naturally from this fractal-scale calculus formalism which may have a key role in the (...)

    A Relativistic Hidden-Variable Interpretation for the Massive Vector Field Based on Energy-Momentum Flows.George Horton & Chris Dewdney - 2010 - Foundations of Physics 40 (6):658-678.
    This paper is motivated by the desire to formulate a relativistically covariant hidden-variable particle trajectory interpretation of the quantum theory of the vector field that is formulated in such a way as to allow the inclusion of gravity. We present a methodology for calculating the flows of rest energy and a conserved density for the massive vector field using the time-like eigenvectors and eigenvalues of the stress-energy-momentum tensor. Such flows may be used to define particle trajectories which follow (...)

    The Combined Impact of Attention to the Deepwater Horizon Oil Spill and Environmental Worldview on Views About Nuclear Energy.Sang-Hwa Oh & John C. Besley - 2013 - Bulletin of Science, Technology and Society 33 (5-6):158-171.
    A two-wave panel study with data collected before and after the 2010 Deepwater Horizon oil spill was used to assess whether the accident changed views toward nuclear energy, a non–fossil fuel energy alternative. While the spill appears to have had little impact on mean attitudes toward nuclear energy, an interaction between environmental worldview and attention to oil spill news suggests the importance of exploring conditional relationships. Specifically, modeling suggests that only those without relatively pro-environmental worldviews became (...)

  27. The Wave Function and Its Evolution.Shan Gao - 2011
    The meaning of the wave function and its evolution are investigated. First, we argue that the wave function in quantum mechanics is a description of random discontinuous motion of particles, and the modulus square of the wave function gives the probability density of the particles being in certain locations in space. Next, we show that the linear non-relativistic evolution of the wave function of an isolated system obeys the free Schrödinger equation due to the requirements of (...)

    The chromodielectric soliton model is Lorentz and chirally invariant. It has been demonstrated to exhibit dynamical chiral symmetry breaking and spatial confinement in the locally uniform approximation. We here study the full nonlocal quark self-energy in a color-dielectric medium modeled by a two-parameter Fermi function. Here color confinement is manifest. The self-energy thus obtained is used to calculate quark wave functions in the medium which, in turn, are used to calculate the nucleon and pion masses in the (...)

    This study draws on achievement goal theory and self-determination theory to examine the associations among two motivational climates (i.e. mastery and performance) and two indicators of energy at work (i.e. vigour and emotional exhaustion), as well as the mediating role of basic psychological need satisfaction (i.e. autonomy, relatedness, and competence). A two-wave longitudinal study was conducted collecting data from 1081 engineers and technologists. We applied previously validated instruments to assess the variables of interest. Structural equation modeling analyses were (...)

    Consciousness is Cheap, Even if Symbols are Expensive; Metabolism and the Brain’s Dark Energy.Seán O. Nualláin & Tom Doris - 2012 - Biosemiotics 5 (2):193-210.
    Use of symbols, the key to the biosemiotics field as to many others, required bigger brains which implied a promissory note for greater energy consumption; symbols are obviously expensive. A score years before the current estimate of 18–20% for the human brain’s metabolic demand on the organism, it was known that neural tissue is metabolically dear. This paper first discusses two evolutionary responses to this demand, on both of which there is some consensus. The first, assigning care of altricial (...)

    Plane Wave Solutions to a Proposed “Equation of Everything”.Robert A. Close - 2025 - Foundations of Physics 55 (2):1-29.
    Plane waves of spin angular momentum density in an ideal elastic solid are analyzed using vector and bispinor descriptions. In both classical and quantum physics, spin density is the axial vector field whose curl is equal to twice the incompressible intrinsic momentum density. The second-order vector wave equation assumes that temporal changes of spin density in an ideal elastic solid are attributable to convection, rotation, and torque density. The corresponding first-order wave equation for Dirac bispinors incorporates terms describing (...)

    The classical wave-particle problem is resolved in accord with Newton's concept of the particle nature of light by associating particle density and flux with the classical wave energy density and flux. Point particles flowing along discrete trajectories yield interference and diffraction patterns, as illustrated by Young's double pinhole interference. Bound particle motion is prescribed by standing waves. Particle motion as a function of time is presented for the case of a “particle in a box.” Initial conditions uniquely (...)

    The Non-vanishing Imprint of Gravitational Waves as the Result of Its Nonlinear Evolution in Space.Ioseph Gurwich - 2023 - Foundations of Physics 53 (5):1-86.
    This paper focuses on the nonlinear self-interaction of gravitational waves and explores its impact on the spectrum of the resulting gravitational wave. While many authors primarily investigate the nonlinear effects within the framework of "gravitational memory," we take a different approach by conducting a comprehensive analysis of harmonic generation. Theoretical analysis indicates that higher harmonics do not possess suitable conditions for energy accumulation. However, our study presents intriguing evidence supporting the concept of "nonlinear gravitational memory": the conversion and (...)

    Quantum mechanics teaches that before detection, knowledge of particle position is, at best, probabilistic, and classical trajectories are seen as a feature of the macroscopic world. These comments refer to detected particles, but we are still free to consider the motions generated by the wave equation. Within hydrogen, the Schrodinger equation allows calculation of kinetic energy at any location, and if this is identified as the energy of the wave, then radial momentum, allowing for spherical harmonics, (...)

    A previous model for treating electromagnetic nonlinear wave systems is examined in the context of wave mechanics. It is shown that nonlinear wave mechanics implies harmonic generation of new quasiparticle wave functions, which are absent in linear systems. The phenomenon is interpreted in terms of pair (and higher order ensembles) coherence of the interacting particles. The implications are far-reaching, and the present approach might contribute toward a common basis for diverse physical phenomena involving nonlinearity. An intimate (...)

    Gravity Waves and LIGO.John Cramer - unknown
    Curiously, in some ways gravity is also the strongest force in the universe. It always adds, never subtracts, and can build up until it overwhelms all other forces.. In normal stars gravity is balanced by heat energy from fusion reactions in the star's core. Eventually, however, the hydrogen and heavier elements fueling these reactions are used up, gravity takes over, and the star collapses in on itself. The result is a supernova explosion, which converts a sizable fraction of the (...)

    Why were Matrix Mechanics and Wave Mechanics considered equivalent?Slobodan Perovic - 2008 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 39 (2):444-461.
    A recent rethinking of the early history of Quantum Mechanics deemed the late 1920s agreement on the equivalence of Matrix Mechanics and Wave Mechanics, prompted by Schrödinger's 1926 proof, a myth. Schrödinger supposedly failed to prove isomorphism, or even a weaker equivalence (“Schrödinger-equivalence”) of the mathematical structures of the two theories; developments in the early 1930s, especially the work of mathematician von Neumann provided sound proof of mathematical equivalence. The alleged agreement about the Copenhagen Interpretation, predicated to a large (...)

    In this paper an attempt is made to interpret inertial mass as a consequence of the invariant periodicity associated with physical de Broglie waves. In the case of a free particle, such waves, observed from an arbitrary reference frame, would exhibit the velocity-dependent wavelength given by de Broglie's relation; and it is conjectured that the inertial and additive properties of mass (or, more precisely, the conservation of momentum and energy) can be related to nonlinear interference effects occurring between the (...)

    The matrix notation of paper I is extended to include first-rank spinors expressed as two-component spin-vectors. Well-known two-component and four-component spinor equations are expressed in this notation. In addition, it is shown how other covariant wave equations can easily be invented. A certain nonlinear equation is found to have only positive-energy solutions for particles and antiparticles.

It generalizes the de Broglie wave. The rays of a particle wave are the possible particle trajectories, and the (...)

    The Nonlinear Essence of Gravitational Waves.R. Aldrovandi, J. G. Pereira & K. H. Vu - 2007 - Foundations of Physics 37 (10):1503-1517.
    A critical review of gravitational wave theory is made. It is pointed out that the usual linear approach to the gravitational wave theory is neither conceptually consistent nor mathematically justified. Relying upon that analysis it is argued that—analogously to a Yang-Mills propagating field, which must be nonlinear to carry its gauge charge—a gravitational wave must necessarily be nonlinear to transport its own charge—that is, energy-momentum.

    Might Quantum-Induced Deviations from the Einstein Equations Detectably Affect Gravitational Wave Propagation?Adrian Kent - 2013 - Foundations of Physics 43 (6):707-718.
    A quantum measurement-like event can produce any of a number of macroscopically distinct results, with corresponding macroscopically distinct gravitational fields, from the same initial state. Hence the probabilistically evolving large-scale structure of space-time is not precisely or even always approximately described by the deterministic Einstein equations.Since the standard treatment of gravitational wave propagation assumes the validity of the Einstein equations, it is questionable whether we should expect all its predictions to be empirically verified. In particular, one might expect the (...)

  47. Why were two theories (matrix mechanics and wave mechanics) deemed logically distinct, and yet equivalent, in quantum mechanics?Slobodan Perovic - 2008 - In Christopher Lehrer, First Annual Conference in the Foundations and History of Quantum Physics. Max Planck Institute for History of Science.
    A recent rethinking of the early history of Quantum Mechanics deemed the late 1920s agreement on the equivalence of Matrix Mechanics and Wave Mechanics, prompted by Schrödinger’s 1926 proof, a myth. Schrödinger supposedly failed to achieve the goal of proving isomorphism of the mathematical structures of the two theories, while only later developments in the early 1930s, especially the work of mathematician John von Neumman (1932) provided sound proof of equivalence. The alleged agreement about the Copenhagen Interpretation, predicated to (...)

    On the direct observability of quantum waves.F. Selleri - 1982 - Foundations of Physics 12 (11):1087-1112.
    Fundamental experiments on the dual nature of atomic entities (photons, electrons, neutrons, etc.) can be interpreted in terms of “empty” waves not carrying energy and momentum. Similar points of view were advanced in famous papers by Einstein, de Broglie, Bohr, and Born. Recent proposals could lead to experimental tests of this idea, using low intensity photon beams, thanks to modern experimental apparatuses.

    Orbit Sum Rules for the Quantum Wave Functions of the Strongly Chaotic Hadamard Billiard in Arbitrary Dimensions.R. Aurich & F. Steiner - 2001 - Foundations of Physics 31 (4):569-592.
    Sum rules are derived for the quantum wave functions of the Hadamard billiard in arbitrary dimensions. This billiard is a strongly chaotic (Anosov) system which consists of a point particle moving freely on a D-dimensional compact manifold (orbifold) of constant negative curvature. The sum rules express a general (two-point)correlation function of the quantum mechanical wave functions in terms of a sum over the orbits of the corresponding classical system. By taking the trace of the orbit sum rule or (...)

    Relational Space-Time and de Broglie Waves.Tony Lyons - 2023 - Foundations of Physics 53 (4):1-26.
    Relative motion of particles is examined in the context of relational space-time. It is shown that de Broglie waves may be derived as a representation of the coordinate maps between the rest-frames of these particles. Energy and momentum are not absolute characteristics of these particles, they are understood as parameters of the coordinate maps between their rest-frames. It is also demonstrated the position of a particle is not an absolute, it is contingent on the frame of reference used to (...)
