    On the Unification of Geometric and Random Structures Through Torsion Fields: Brownian Motions, Viscous and Magneto-Fluid-Dynamics.Diego L. Rapoport - 2005 - Foundations of Physics 35 (7):1205-1244.
    We present the unification of Riemann–Cartan–Weyl space-time geometries and random generalized Brownian motions. These are metric compatible connections which have a propagating trace-torsion 1-form, whose metric conjugate describes the average motion interaction term. Thus, the universality of torsion fields is proved through the universality of Brownian motions. We extend this approach to give a random symplectic theory on phase-space. We present as a case study of this approach, the invariant Navier–Stokes equations for viscous fluids, and the kinematic dynamo (...)

    Cartan–Weyl Dirac and Laplacian Operators, Brownian Motions: The Quantum Potential and Scalar Curvature, Maxwell’s and Dirac-Hestenes Equations, and Supersymmetric Systems. [REVIEW]Diego L. Rapoport - 2005 - Foundations of Physics 35 (8):1383-1431.
    We present the Dirac and Laplacian operators on Clifford bundles over space–time, associated to metric compatible linear connections of Cartan–Weyl, with trace-torsion, Q. In the case of nondegenerate metrics, we obtain a theory of generalized Brownian motions whose drift is the metric conjugate of Q. We give the constitutive equations for Q. We find that it contains Maxwell’s equations, characterized by two potentials, an harmonic one which has a zero field (Bohm-Aharonov potential) and a coexact term that generalizes the (...)

    Torsion Fields, Cartan–Weyl Space–Time and State-Space Quantum Geometries, Their Brownian Motions, and the Time Variables.Diego L. Rapoport - 2007 - Foundations of Physics 37 (4-5):813-854.
    We review the relation between spacetime geometries with trace-torsion fields, the so-called Riemann–Cartan–Weyl (RCW) geometries, and their associated Brownian motions. In this setting, the drift vector field is the metric conjugate of the trace-torsion one-form, and the laplacian defined by the RCW connection is the differential generator of the Brownian motions. We extend this to the state-space of non-relativistic quantum mechanics and discuss the relation between a non-canonical quantum RCW geometry in state-space associated with the gradient of the (...)

  7. Why Continuous Motions Cannot Be Composed of Sub-Motions: Aristotle on Change, Rest, and Actual and Potential Middles.Caleb Cohoe - 2018 - Apeiron 51 (1):37-71.
    I examine the reasons Aristotle presents in Physics VIII 8 for denying a crucial assumption of Zeno’s dichotomy paradox: that every motion is composed of sub-motions. Aristotle claims that a unified motion is divisible into motions only in potentiality (δυνάμει). If it were actually divided at some point, the mobile would need to have arrived at and then have departed from this point, and that would require some interval of rest. Commentators have generally found Aristotle’s reasoning unconvincing. Against (...)

    Reading Emotion From Mouse Cursor Motions: Affective Computing Approach.Takashi Yamauchi & Kunchen Xiao - 2018 - Cognitive Science 42 (3):771-819.
    Affective computing research has advanced emotion recognition systems using facial expressions, voices, gaits, and physiological signals, yet these methods are often impractical. This study integrates mouse cursor motion analysis into affective computing and investigates the idea that movements of the computer cursor can provide information about emotion of the computer user. We extracted 16–26 trajectory features during a choice-reaching task and examined the link between emotion and cursor motions. Participants were induced for positive or negative emotions by music, film (...)

    Gesture, Landscape and Embrace: A Phenomenological Analysis of Elemental Motions.Stephen J. Smith - 2006 - Indo-Pacific Journal of Phenomenology 6 (1):1-10.
    Maurice Merleau-Ponty’s ‘flesh of the world’ speaks to an embodied connection to the spaces we inhabit deeply, primally, elementally. Flesh suggests water and its circulations, air and its respirations, earth and its conformations, fire and its inspirations. Flesh speaks to our bodily relations with the elements of a more-than-human world. This paper explores the felt imperative to these relations where, as Merleau-Ponty put it, ‘all distance is traversed’ and wherein movement arises not specifically in the body, but in the nexus (...)

    Hobbes, Galileo, and the Physics of Simple Circular Motions.John Henry - 2016 - Hobbes Studies 29 (1):9-38.
    _ Source: _Volume 29, Issue 1, pp 9 - 38 Hobbes tried to develop a strict version of the mechanical philosophy, in which all physical phenomena were explained only in terms of bodies in motion, and the only forces allowed were forces of collision or impact. This ambition puts Hobbes into a select group of original thinkers, alongside Galileo, Isaac Beeckman, and Descartes. No other early modern thinkers developed a strict version of the mechanical philosophy. Natural philosophies relying solely on (...)

    Superluminal Motions? A Bird's-Eye View of the Experimental Situation.Erasmo Recami - 2001 - Foundations of Physics 31 (7):1119-1135.
    In this article, after a theoretical introduction and a sketch of some related long-standing predictions, a bird's-eye view is presented—with the help of nine figures—of the various experimental sectors of physics in which Superluminal motions seem to appear (thus contributing support to those past predictions). In particular, a panorama is presented of the experiments with evanescent waves and/or tunnelling photons, and with the “localized Superluminal solutions” to the Maxwell equations (like the so-called X-shaped beams). The present review is brief, (...)

    Celestial Motions in the Late Middle Ages.Edward Grant - 1997 - Early Science and Medicine 2 (2):129-148.
    With the introduction of Greco-Islamic science and natural philosophy, medieval natural philosophers were confronted with three distinct astronomical systems: Aristotelian, Ptolemaic, and the system of al-Bitruji. A fundamental problem that each had to confront was how to explain simultaneous contrary motions in the heavens -for example, the sun's motion, which moves east to west with a daily motion while simultaneously moving west to east along the ecliptic- within an Aristotelian physical system that assumed that a simple body could have (...)

  13. Mean Motions in Ptolemy’s Planetary Hypotheses.Dennis Duke - 2009 - Archive for History of Exact Sciences 63 (6).
    In the Planetary Hypotheses, Ptolemy summarizes the planetary models that he discusses in great detail in the Almagest, but he changes the mean motions to account for more prolonged comparison of observations. He gives the mean motions in two different forms: first, in terms of ‘simple, unmixed’ periods and next, in terms of ‘particular, complex’ periods, which are approximations to linear combinations of the simple periods. As a consequence, all of the epoch values for the Moon and the (...)

    Absence of Radiationless Motions of Relativistically Rigid Classical Electron.Philip Pearle - 1977 - Foundations of Physics 7 (11-12):931-945.
    Radiationless motion of a charge distribution is reviewed, and the necessary condition conjectured by Goedecke is proved. Then it is shown that a nonrotating, uniformly charged, spherical shell (as seen from its own rest frame) which moves in a relativistically invariant fashion does not have any bounded radiationless motions, unlike its nonrelativistic counterpart.

    The Mathematics of Symmetry Does Not Provide an Appropriate Model for the Human Understanding of Elementary Motions.John R. Pani - 2001 - Behavioral and Brain Sciences 24 (4):696-697.
    Shepard's article presents an impressive application of the mathematics of symmetry to the understanding of motion. However, there are basic psychological phenomena that the model does not handle well. These include the importance of the orientations of rotational motions to salient reference systems for the understanding of the motions. An alternative model of the understanding of rotations is sketched. [Shepard].

    Bodily Motions and Religious Feelings.Gareth B. Matthews - 1971 - Canadian Journal of Philosophy 1 (1):75 - 86.
    For when men pray they do with the members of their bodies what befits suppliants—when they bend their knees and stretch out their hands, or even prostrate themselves, and whatever else they do visibly, although their invisible will and the intention of their heart is known to God. Nor does He need these signs for the human mind to be laid bare to Him. But in this way a man excites himself to pray more and to groan more humbly and (...)

    Consciousness Mediated by Neural Transition States: How Invisibly Rapid Motions Can Become Visible.Uwe Mattler & Robert Fendrich - 2010 - Consciousness and Cognition 19 (1):172-185.
    When observers view a rapidly moving stimulus they may see only a static streak. We report that there can be a transient percept of motion if such a moving stimulus is preceded or followed by a stationary image of that stimulus. A ring of dots was rotated so rapidly observers only saw a continuous outline circle and could not report its rotation direction. When an objectively stationary ring of dots preceded or followed this rotating ring, the stationary ring appeared to (...)

    This article examines how the interactive capabilities of companion robots, particularly their materiality and animate movements, appeal to human users and generate an image of aliveness. Building on Husserl’s phenomenological notion of a ‘double body’ and theories of emotions as affective responses, we develop a new understanding of the robots’ simulated aliveness. Analyzing empirical findings of a field study on the use of the robot Zora in care homes for older people, we suggest that the aliveness of companion robots is (...)

    Motions in the Body, Sensations in the Mind: Malebranche's Mechanics of Sensory Perception and Taste.Katharine Julia Hamerton - forthcoming - Arts Et Savoirs.
    This article, which seeks to connect philosophy, polite culture, and the Enlightenment, shows how Malebranche’s Cartesian science presented a full-frontal attack on the worldly notion of a good taste aligned with reason. It did this by arguing that the aesthetic tastes that people experience were the result of mechanically-transmitted sensations that, like all physical sensations, were inaccurate, erroneous and relativistic. The mechanics of this process is explored in detail to show how Malebranche was challenging honnête thinking. The article suggests that (...)

    "From the Phenomena of Motions to the Forces of Nature": Hypothesis or Deduction?Howard Stein - 1990 - PSA: Proceedings of the Biennial Meeting of the Philosophy of Science Association 1990:209 - 222.
    This paper examines Newton's argument from the phenomena to the law of universal gravitation-especially the question how such a result could have been obtained from the evidential base on which that argument rests. Its thesis is that the crucial step was a certain application of the third law of motion-one that could only be justified by appeal to the consequences of the resulting theory; and that the general concept of interaction embodied in Newton's use of the third law most probably (...)

    Tubes, Randomness, and Brownian Motions: Or, How Engineers Learned to Start Worrying About Electronic Noise.Chen-Pang Yeang - 2011 - Archive for History of Exact Sciences 65 (4):437-470.
    In this paper, we examine the pioneering research on electronic noise—the current fluctuations in electronic circuit devices due to their intrinsic physical characteristics rather than their defects—in Germany and the U.S. during the 1910s–1920s. Such research was not just another demonstration of the general randomness of the physical world Einstein’s work on Brownian motion had revealed. In contrast, we stress the importance of a particular engineering context to electronic noise studies: the motivation to design and improve high-gain thermionic-tube amplifiers for (...)

    This article explores how Plato, in his “metaphysical” dialogues, sees the specific properties of motion (and especially of motion in music), which lend themselves to adaptation for the purposes of maintaining or restoring the health of the soul. Plato explores the property of regular or rhythmic motion in particular. The attention has been drawn to the analogy between the calming effect of music, at the human level, and the Demiurge’s achievement in willing the world into existence. The focus of the (...)

    From Bodily Motions to Bodily Intentions: The Perception of Bodily Activity.William S. Wilkerson - 1999 - Philosophical Psychology 12 (1):61-77.
    This paper argues that one's perception of another person's bodily activity is not the perception of the mere flexing and bending of that person's limbs, but rather of that person's intentions. It makes its case in three parts. First, it examines what conditions are necessary for children to begin to imitate and assimilate the behavior of other adults and argues that these conditions include the perception of intention. These conditions generalize to adult perception as well. Second, changing methodologies, the paper (...)

    The concept of rigid reference frame and of constricted spatial metric, given in the previous work [Class. Quantum Grav. 21, 3067 (2004)] are here applied to some specific space-times: in particular, the rigid rotating disc with constant angular velocity in Minkowski space-time is analyzed, a new approach to the Ehrenfest paradox is given as well as a new explanation of the Sagnac effect. Finally the anisotropy of the speed of light and its measurable consequences in a reference frame co-moving with (...)

    Possible Test of the Reality of Superluminal Phase Waves and Particle Phase Space Motions in the Einstein-de Broglie-Bohm Causal Stochastic Interpretation of Quantum Mechanics.J. P. Vigier - 1994 - Foundations of Physics 24 (1):61-83.
    Recent double-slit type neutron experiments (1) and their theoretical implications (2) suggest that, since one can tell through which slit the individual neutrons travel, coherent wave packets remain nonlocally coupled (with particles one by one), even in the case of wide spatial separation. Following de Broglie's initial proposal, (3) this property can be derived from the existence of the persisting action of real superluminal physical phase waves considered as building blocks of the real subluminal wave field packets which surround individual (...)
