    A minor or a major predicament of physical theory? (Charge and action polarity and their order properties).E. J. Post - 1977 - Foundations of Physics 7 (3-4):255-277.
    The questions of observational error and ambiguity of interpretation that have been raised in connection with the reported observation of a magnetic monopole have precipitated a situation calling for some further insight into the pairing principles of nature. A basic distinction relates to whether or not a pair is “ordered” (e.g., sexual pair) or without a priori order (e.g., mirror pair). It is shown that the polarity of electric charge is to be regarded as an example of pairing without an (...)

    Magnetic symmetry, improper symmetry, and Neumann's principle.E. J. Post - 1978 - Foundations of Physics 8 (3-4):277-294.
    Mathematical tradition has it that transformations characterized by a negative Jacobian determinant are referred to as improper transformations. The symmetry of a physical object corresponding to such an improper transformation becomes an improper symmetry. Improper symmetries have been successfully used for the purpose of crystal symmetry. The extension of these purely spatial symmetries to the domain of spacetime has led to a prejudicial use of light-cone properties, thus affecting adversely an unbiased symmetry classification. We pinpoint these prejudicial procedures and trace (...)

    Comments on “Parity and time inversion symmetries of electromagnetic systems” by R. M. Kiehn.E. J. Post - 1979 - Foundations of Physics 9 (5-6):421-424.
    Previous statements concerning the reduction of possible parity and time reversal choices for electromagnetic quantities are amplified for the sake of clearer understanding.

    Kottler-Cartan-van Dantzig (KCD) and noninertial systems.E. J. Post - 1979 - Foundations of Physics 9 (7-8):619-640.
    Kottler, Cartan, and van Dantzig independently uncovered a key property of the Maxwell equations, which, in retrospect, is instrumental for treating noninertial situations. The essence of this KCD procedure is outlined. Present traditions incompatible with the KCD procedure are identified. KCD predicts a rotation-induced magnetoelectric effect in vacuum, as verified by the experiments of Kennard and Pegram. The description of nonvacuum situations still has some unresolved differences awaiting further experimental delineation. Explicit calculations and technical specifications of experiments receive references to (...)

    Physical dimensions and covariance.E. J. Post - 1982 - Foundations of Physics 12 (2):169-195.
    The nonadditive properties of mass make it desirable to abandon mass as a basis unit in physics and to replace it by a unit of the dimension of the quantum of action [h]. The ensuing four-unit system of action, charge, length, and time [h, q, l, t] interacts in a much more elucidating fashion with experiment and with the fundamental structure of physics. All space-time differential forms expressing fundamental laws of physics are forms of physical dimensions, h, h/q, or q. (...)

    Time asymmetries in classical and in nonclassical physics.E. J. Post - 1979 - Foundations of Physics 9 (11-12):831-863.
    A comparative study is made of the eigenvalue problems of electromagnetics and quantum mechanics, with special reference to the operations of spatial inversionP and time inversionT. Electromagnetics, which permits closer agreement with the dictates of relativity (when the latter is extended toP andT), exhibits characteristic differences with respect to quantum mechanics. An evaluation of these distinctions is presented against the backdrop of a choice between absolute scalar action and charge versus pseudoscalar action and charge.

    The logic of time reversal.E. J. Post - 1979 - Foundations of Physics 9 (1-2):129-161.
    Active time reversal in the sense of “object reversal” and passive time reversal in the sense of a frame reversal of time are discussed separately and then together so as to bring out their dual nature. An understanding of that duality makes it unavoidable to contrast symmetry properties of matter with symmetry properties to be assigned to antimatter. Only frame reversal of time can “see” all conceivable active time reversals relevant to physical objects. Only frame reversal of time can be (...)
