This paper is a review of the canonical proper-time approach to relativistic mechanics and classical electrodynamics. The purpose is to provide a physically complete classical background for a new approach to relativistic quantum theory. Here, we first show that there are two versions of Maxwell’s equations. The new version fixes the clock of the field source for all inertial observers. However now, the (natural definition of the effective) speed of light is no longer an invariant for all observers, but depends (...) on the motion of the source. This approach allows us to account for radiation reaction without the Lorentz-Dirac equation, self-energy (divergence), advanced potentials or any assumptions about the structure of the source. The theory provides a new invariance group which, in general, is a nonlinear and nonlocal representation of the Lorentz group. This approach also provides a natural (and unique) definition of simultaneity for all observers.The corresponding particle theory is independent of particle number, noninvariant under time reversal (arrow of time), compatible with quantum mechanics and has a corresponding positive definite canonical Hamiltonian associated with the clock of the source.We also provide a brief review of our work on the foundational aspects of the corresponding relativistic quantum theory. Here, we show that the standard square-root and Dirac equations are actually two distinct spin- $\frac{1}{2}$ particle equations. (shrink)

In this paper, we report on a new approach to relativistic quantum theory. The classical theory is derived from a new implementation of the first two postulates of Einstein, which fixes the proper-time of the physical system of interest for all observers. This approach leads to a new group that we call the proper-time group. We then construct a canonical contact transformation on extended phase space to identify the canonical Hamiltonian associated with the proper-time variable. On quantization we get a (...) new relativistic wave equation for spin 1/2 particles that generalizes the Dirac theory. The Hamiltonian is positive definite so we naturally interpret antiparticles as particles with their proper-time reversed. We show that for the hydrogen atom problem, we get the same fine structure separation. When the proton spin magnetic moment is taken into account, we get the standard hyperfine splitting terms of the Pauli approximation and two additional terms. The first term is small in p-states. It diverges in s-states, and provides more than enough to account for the Lamb-shift when the proton radius is used as a cut off. The last term promises to provide a correction to the hyperfine splitting term. Although incomplete, the general approach offers hope of completely accounting for the hydrogen spectrum as an eigenvalue problem. (shrink)

It was shown in Dirac A117, 610; A118, 351, 1928) that the ultra-violet divergence in quantum electrodynamics is caused by a violation of the time-energy uncertainly relationship, due to the implicit assumption of infinitesimal time information. In Wheeler et al. it was shown that Einstein’s special theory of relativity and Maxwell’s field theory have mathematically equivalent dual versions. The dual versions arise from an identity relating observer time to proper time as a contact transformation on configuration space, which leaves phase (...) space invariant. The special theory has a dual version in the sense that, for any set of n particles, every observer has two unique sets of global variables \\) and \\) to describe the dynamics, where \ is the canonical center of mass. In the \\) variables, time is relative and the speed of light is unique, while in the \\) variables, time is unique and the speed of light is relative with no upper bound. In the Maxwell case, the two sets of particle wave equations are not equivalent. The dual version contains an additional longitudinal radiation term that appears instantaneously with acceleration, leading to the prediction that radiation from a cyclotron will not produce photoelectrons. A major outcome is the dual unification of Newtonian mechanics and classical electrodynamics with Einstein’s special theory of relativity, without the need for point particles, without a self-energy divergency and, without need for the problematic Lorentz–Dirac equation. The purpose of this paper is to introduce the dual theory of relativistic quantum mechanics. In our approach, we obtain three distinct dual relativistic wave equations that reduce to the Schrödinger equation when minimal coupling is turned off. We show that the dual Dirac equation provides a new formula for the anomalous magnetic moment of a charged particle. We can obtain the exact value for the electron g-factor and phenomenological values for the muon and proton g-factors. (shrink)

In this paper, we construct a parallel image of the conventional Maxwell theory by replacing the observer-time by the proper-time of the source. This formulation is mathematically, but not physically, equivalent to the conventional form. The change induces a new symmetry group which is distinct from, but closely related to the Lorentz group, and fixes the clock of the source for all observers. The new wave equation contains an additional term (dissipative), which arises instantaneously with acceleration. This shows that the (...) origin of radiation reaction is not the action of a “charge” on itself but arises from inertial resistance to changes in motion. This dissipative term is equivalent to an effective mass so that classical radiation has both a massless and a massive part. Hence, at the local level the theory is one of particles and fields but there is no self-energy divergence (nor any of the other problems). We also show that, for any closed system of particles, there is a global inertial frame and unique (invariant) global proper-time (for each observer) from which to observe the system. This global clock is intrinsically related to the proper clocks of the individual particles and provides a unique definition of simultaneity for all events associated with the system. We suggest that this clock is the historical clock of Horwitz, Piron, and Fanchi. At this level, the theory is of the action-at-a-distance type and the absorption hypothesis of Wheeler and Feynman follows from global conservation of energy. (shrink)

This paper focuses on the remains of the Baptistery chapel within the North Church complex on the outskirts of Shivta, a fifth-seventh century Byzantine village in the Negev. Presumably a monastery, the North Church is the largest and most elaborately constructed of the three Shivta churches. After addressing general structural and chronological issues of the complex, a comparison of the North Church Baptistery to the South Church Baptistery aims to clarify the linkage between shape and ritual. The authors propose that (...) the earlier South Church Baptistery probably served the public, while the later North Church Baptistery fulfilled the internal needs of the monastery. The remains of the Baptism of Christ wall painting, recently rediscovered in the apse of the North Church Baptistery, complements, even if partially, knowledge of the links between architecture, liturgy, and art within the space. The study offers a glimpse into the religious and cultural world of the people who lived in this arid and remote, but by no means isolated area. (shrink)

The canonical proper time formulation of relativistic dynamics provides a framework from which one can describe the dynamics of classical and quantum systems using the clock of those very systems. The framework utilizes a canonical transformation on the time variable that is used to describe the dynamics, and does not transform other dynamical variables such as momenta or positions. This means that the time scales of the dynamics are described in terms of the natural local time coordinates, which is the (...) most meaningful parameterization of phenomena such as the approach to equilibrium, or the back reaction of interacting systems. We summarize the formalism of the canonical proper time framework, and provide example calculations of the eigenvalues of the hydrogen atom and near horizon description of a scalar field near a Schwarzschild black hole.

This paper posits that ethical leadership increases important organizational and individual outcomes by reducing politics in the workplace. Specifically, we propose that perceptions of organizational politics serve as a mechanism through which ethical leadership affects outcomes. We further argue that the modeled relationships are moderated by political skill. By means of data from 136 matched pairs of supervisors and subordinates employed by a state agency in the southern US, we found support for our predictions. Specifically, we found that perceptions of (...) organizational politics fully mediated the relationship between perceptions of ethical leadership and helping and promotability ratings. In addition, political skill was found to moderate the direct and indirect effects. (shrink)

In the academic year 1920-1921 at the University of Freiburg, Martin Heidegger gave a series of extraordinary lectures on the phenomenological significance of the religious thought of St. Paul and St. Augustine. The publication of these lectures in 1995 settled a long disputed question, the decisive role played by Christian theology in the development of Heidegger’s philosophy. The lectures present a special challenge to readers of Heidegger and theology alike. Experimenting with language and drawing upon a wide range of now (...) obscure authors, Heidegger is finding his way to Being and Time through the labyrinth of his Catholic past and his increasing fascination with Protestant theology. A Companion to Heidegger's Phenomenology of Religious Life is written by an international team of Heidegger specialists. (shrink)

In print for the first time in over ten years, Act and Crime provides a unified account of the theory of action presupposed by both Anglo-American criminal law and the morality that underlies it. The book defends the view that human actions are always volitionally caused bodily movements and nothing else. The theory is used to illuminate three major problems in the drafting and the interpretation of criminal codes: 1) what the voluntary act requirement both does and should require; 2) (...) what complex descriptions of actions prohibited by criminal codes both do and should require ; and 3) when two actions are 'the same' for purposes of assessing whether multiple prosecutions and multiple punishments are warranted. The book both contributes to the development of a coherent theory of action in philosophy, and it provides both legislators and judges a grounding in three of the most basic elements of criminal liability.

In this short, dense essay, Jean Cavaillès evaluates philosophical efforts to determine the origin - logical or ontological - of scientific thought, arguing that, rather than seeking to found science in original intentional acts, a priori meanings, or foundational logical relations, any adequate theory must involve a history of the concept. Cavaillès insists on a historical epistemology that is conceptual rather than phenomenological, and a logic that is dialectical rather than transcendental. His famous call (cited by Foucault) to abandon "a (...) philosophy of consciousness" for "a philosophy of the concept" was crucial in displacing the focus of philosophical enquiry from aprioristic foundations toward structural historical shifts in the conceptual fabric. This new translation of Cavaillès's final work, written in 1942 during his imprisonment for Resistance activities, presents an opportunity to reencounter an original and lucid thinker. Cavaillès's subtle adjudication between positivistic claims that science has no need of philosophy, and philosophers' obstinate disregard for actual scientific events, speaks to a dilemma that remains pertinent for us today. His affirmation of the authority of scientific thinking combined with his commitment to conceptual creation yields a radical defense of the freedom of thought and the possibility of the new.

In Alfonso de Cartagena's 'Memoriale virtutum' (1422) María Morrás and Jeremy Lawrance offer a new edition from the manuscripts of a compilation of Aristotle's Nicomachean Ethics addressed by the major Castilian intellectual of the day, bishop Alfonso de Cartagena, to the heir to the throne of Portugal, crown prince Duarte. The work was a speculum principis, an education for the future king in the virtues suitable to a statesman; Cartagena's choice of Aristotle was thus a significant index of the advent (...) of new Renaissance ideas. This edition shows how the "memorial" throws light on the ideological transformation of society those ideas would bring, setting new ethical guidelines for the ruling class at the crossroads between medieval feudalism and Renaissance absolutism.

Abstract:During the early 19th century, a peculiarly systematic way of organizing books emerged in Germany. This systematization, which purported to be a rational organization of subject matter, was an outgrowth of the philosophy of Hegel. This article attempts to outline Hegel's organizational practice. It argues that Hegel's encyclopedia was a reaction against the Enlightenment encyclopedia, and that it attempted to restore the systematic mindset of pre-modern reference books. Yet it did this, not in a straightforward fashion, but by developing a (...) method for organizing material that both stresses the interconnectedness of knowledge and promises to be highly scalable. In its attempt to trace the Hegelian organizational method, this article revisits and calls attention to a forgotten work in Hegel scholarship by Michael John Petry, who was the first writer to seriously stress the importance of classification in Hegel's work. This article is an attempt to demonstrate that Hegelianism and information organization can be brought into fruitful and mutually beneficial dialogue. (shrink)
