    Time Symmetry and Interpretation of Quantum Mechanics.O. Costa de Beauregard - 1976 - Foundations of Physics 6 (5):539-559.
    A drastic resolution of the quantum paradoxes is proposed, combining (I) von Neumann's postulate that collapse of the state vector is due to the act of observation, and (II) my reinterpretation of von Neumann's quantal irreversibility as an equivalence between wave retardation and entropy increase, both being “factlike” rather than “lawlike” (Mehlberg). This entails a coupling of the two de jure symmetries between (I) retarded and (II) advanced waves, and between Aristotle's information as (I) learning and (II) willing awareness. Symmetric (...)

  2. On Some Frequent but Controversial Statements Concerning the Einstein-Podolsky-Rosen Correlations.O. Costa de Beauregard - 1985 - Foundations of Physics 15 (8):871-887.
    Quite often the compatibility of the EPR correlations with the relativity theory has been questioned; it has been stated that “the first in time of two correlated measurements instantaneously collapses the other subsystem”; it has been suggested that a causal asymmetry is built into the Feynman propagator. However, the EPR transition amplitude, as derived from the S matrix, is Lorentz andCPT invariant; the correlation formula is symmetric in the two measurements irrespective of their time ordering, so that the link of (...)

    CPT Invariance and Interpretation of Quantum Mechanics.O. Costa de Beauregard - 1980 - Foundations of Physics 10 (7-8):513-530.
    This paper is a sequel to various papers by the author devoted to the EPR correlation. The leading idea remains that the EPR correlation (either in its well-known form of nonseparability of future measurements, or in its less well-known time-reversed form of nonseparability of past preparations) displays the intrinsic time symmetry existing in almost all physical theories at the elementary level. But, as explicit Lorentz invariance has been an essential requirement in both the formalization and the conceptualization of my papers, (...)

    The Computer and the Heat Engine.O. Costa de Beauregard - 1989 - Foundations of Physics 19 (6):725-727.
    Brillouin sees order as generated by tapping negentropy sources existing upstream, while Prigogine sees it as generated by dumping entropy downstream. Joining both ideas yields a picture of the computer closely paralleling that of Carnot's heat engine. The difference is that the one delivers information and the other, work. In either case the irretrievable (that is, by definition) loss occurs at the last step. Bennett and Landauer very rightly emphasize this, but their fixation on the condenser blinds them to the (...)

  5. On the Joint Probability of Correlated Physical Occurrences.O. Costa de Beauregard - 1996 - Foundations of Physics 26 (3):391-399.
    Correlation meaning interaction for physical occurrences, the joint probability formalizes this interaction and conceptualizes a stochastic causality. Bayesian reversibility then expresses action-reaction symmetry for spacelike, und cause-effect symmetry for timelike, separations. Information-negeutropy equivalence (that is. reversibility of the twin-faced information concept) extends Mehlberg's “lawlike reversibility” and vindicates Wigner's claim that psychokinesis is reciprocal to gain in knowledge. A covariant axiomatization of probabilities as expressing physical interaction, and displaying the spacetime propagation of information, is proposed. Its correspondence (but essential difference) with (...)

    To Believe Or Not Believe In The A Potential, That’s a Question. Flux Quantization in Autistic Magnets. Prediction of a New Effect.O. Costa de Beauregard - 2004 - Foundations of Physics 34 (11):1695-1702.
    Electromagnetic gauge as an integration condition was my wording in previous publications. I argue here, on the examples of the Möllenstaedt-Bayh and Tonomura tests of the Ahraronov–Bohm (AB) effect, that not only the trapped flux Φ but also, under the integration condition A ≡ 0 if Φ = 0, the local value of the vector potential is measured.

    On the Zigzagging Causility Model of EPR Correlations and on the Interpretation of Quantum Mechanics.O. Costa de Beauregard - 1988 - Foundations of Physics 18 (9):913-938.
    Being formalized inside the S-matrix scheme, the zigzagging causility model of EPR correlations has full Lorentz and CPT invariance. EPR correlations, proper or reversed, and Wheeler's smoky dragon metaphor are respectively pictured in spacetime or in the momentum-energy space, as V-shaped, A-shaped, or C-shaped ABC zigzags, with a summation at B over virtual states |B〉 〈B|. An exact “correspondence” exists between the Born-Jordan-Dirac “wavelike” algebra of transition amplitudes and the 1774 Laplace algebra of conditional probabilities, where the intermediate summations |B) (...)

    It is argued that the so‐called correlation paradoxes of Einstein‐Podolsky‐Rosen1 and of Schrödinger2 imply that individual quantum processes are connected in time in a way that is symmetric with retarded and advanced actions; a · fatalistic · character of the course of events is thus advocated, similar to the one occuring in the so‐called · Heisenberg picture · in hyperquanitized field theory.

    On the Zigzagging Causality EPR Model: Answer to Vigier and Coworkers and to Sutherland. [REVIEW]O. Costa de Beauregard - 1987 - Foundations of Physics 17 (8):775-785.
    The concept of “propagation in time” of Vigier and co-workers (V et al.) implies the idea of a supertime; it is thus alien to most Minkowskian pictures and certainly to mine. From this stems much of Vet al.'s misunderstandings of my position. In steady motion of a classical fluid nobody thinks that “momentum conservation is violated,” or that “momentum is shot upstream without cause” because of the suction from the sinks! Similarly with momentum-energy in space-time and the acceptance of an (...)

    Is There a Reality Out There?O. Costa de Beauregard - 1992 - Foundations of Physics 22 (1):121-135.
    Joseph Bertrand's 1888 evidencing that assignment of a probability depends upon what one chooses to know or not and to control or not, congruent with Grad's 1961 evidencing that statistical entropy depends upon what one deems relevant or not in formalization and measurement, radically undermine common sense realism; mean values are symbols, but symbols of what? For that very reason, recent clever conceptualizations of the quantum measurement process via partial tracing do not restore realism: How could deliberate ignorance generate a (...)

    Electromagnetic Gauge as an Integration Condition: De Broglie's Argument Revisited and Expanded. [REVIEW]O. Costa de Beauregard - 1992 - Foundations of Physics 22 (12):1485-1494.
    Einstein's mass-energy equivalence law, argues de Broglie, by fixing the zero of the potential energy of a system,ipso facto selects a gauge in electromagnetism. We examine how this works in electrostatics and in magnetostatics and bring in, as a “trump card,” the familiar, but highly peculiar, system consisting of a toroidal magnet m and a current coil c, where none of the mutual energy W resides in the vacuum. We propose the principle of a crucial test for measuring the fractions (...)

    Relativistic Quantum Mechanics as a Telegraph.O. Costa de Beauregard - 2001 - Foundations of Physics 31 (5):837-848.
    A derivation by Fröhner of non-relativistic quantum mechanics via Fourier analysis applied to probability theory is not extendable to relativistic quantum mechanics because Schrödinger's positive definite probability density ψ*ψ is lost (Dirac's spin 1/2 case being the exception). The nature of the Fourier link then changes; it points to a redefinition of the probability scheme as an information carrying telegraph, the code of which is Born's as extended by Dirac and by Feynman. Hermitian symmetry of the transition amplitude 〈ϕ∣ψ〉 between (...)

    Helmholtz’ electrically induced extra mass inside a charged hollow sphere, recently evidenced by Mikhailov, is analogous to Mach’s inertial mass. Existence of a corresponding magnetically induced extra mass in an electron flying around an “autistic magnet” is derived. The overall electro-magnetic effect can be covariantly expressed.

    MPT Versus: A Manifestly Covariant Presentation of Motion Reversal and Particle-Antiparticle Exchange. [REVIEW]O. Costa de Beauregard - 1982 - Foundations of Physics 12 (9):861-871.
    We show that particle-antiparticle exchange and covariant motion reversal are two physically different aspects of the same mathematical transformation, either in the prequantal relativistic equation of motion of a charged point particle, in the general scheme of second quantization, or in the spinning wave equations of Dirac and of Petiau-Duffin-Kemmer. While, classically, charge reversal and rest mass reversal are equivalent operations, in the wave mechanical case mass reversal must be supplemented by exchange of the two adjoint equations, implying ψ ⇄ (...)

    Bohr's Discussion of the Fourth Uncertainty Relation Revisited.O. Costa de Beauregard - 1986 - Foundations of Physics 16 (9):937-939.
    Bohr's 1930 derivation of the uncertainty relation c 2 δm δt≥h bears a close relationship to Einstein's 1913 derivation of the “gravitational redshift” via the “equivalence principle.” A rewording of Bohr's argument is presented here, not taking the last step of acceleration as “equivalent” to a uniform gravity field, thus yielding a derivation of the formula c 2 δm δt≥h, avoiding Treder's 1971 objection.

    The two photon problem defined by Vigier and Garuccio should be treated in the second quantization formalism; it is, thus, seen that the amplitude for finding one photon in the interference region of the two lasers remains the sum of the two interfering amplitudes.

    Relativistic Dynamics of Interacting Point Particles: Central Position of the Wheeler-Feynman Scheme. [REVIEW]O. Costa de Beauregard - 1985 - Foundations of Physics 15 (6):731-736.
    The Wheeler-Feynman (WF) relativistic theory of interacting point particles, generalized by acceptance of an arbitrary spacelike interaction, is shown to possess a privileged status, reminiscent of the “central force” interactions occurring in Newtonian mechanics. This scheme is shown to be isomorphic to the classical one of the statics of interacting flexible current-carrying wires obeying the Ampère-Laplace (AL) formulas: to the tensionT (T 2 =const) of the wire corresponds the momentum-energy pi (pipi=−c2m2) of the particle; to the Laplace linear force density (...)
