    The Dilemma of the Continuity of Matter / O Dilema da Continuidade da Matéria.Rodrigo Cid - 2011 - Revista Do Seminário Dos Alunos Do PPGLM/UFRJ 2:paper 2.
    In this paper I intend to present the Dilemma of Continuity of Matter and a possible solution to it. This dilemma consists in choosing between two misfortunes in explaining the continuity of matter: or to say that material objects are infinitely divisible and not explain what constitutes the continuity of some kind of object, or to say that there is a certain kind of indivisible object and not explain what constitutes the continuity of such an object. The solution we provide (...)

    Was Gassendi an Epicurean?Monte Ransome Johnson - 2003 - History of Philosophy Quarterly 20 (4):339 - 360.
    Pierre Gassendi was a major factor in the revival of Epicureanism in early modern philosophy, not only through his contribution to the restoration and criticism of Epicurean texts, but also by his adaptation of Epicurean ideas in his own philosophy, which was itself influential on such important figures of early modern philosophy as Hobbes, Locke, Newton, and Boyle (to name just a few). Despite his vigorous defense of certain Epicurean ideas and ancient atomism, Gassendi goes to great lengths to differentiate (...)

    Materia: Solide, Lichide, Gaze, Plasma - Fenomenologie.Nicolae Sfetcu - 2018 - Drobeta Turnu Severin: MultiMedia Publishing.
    O perspectivă contemporană asupra materiei, care ia în considerare toate entităţile ştiinţifice observabile, cu accent pe fenomene. În principiu, definiţia materiei se limitează la astfel de entităţi explorate de fizică. În funcţie de condiţiile termodinamice diferite, cum ar fi temperatura şi presiunea, materia poate exista în diferite “faze”, cele mai familiare fiind cele de solid, lichid, şi gaz. Alte faze pot fi cele de plasmă, superfluid, şi condensat Bose-Einstein. Atunci când materia trece dintr-o fază în alta, este supusă la ceea (...)

    New Foundations for Qualitative Physics.Jean Petitot & Barry Smith - 1990 - In J. E. Tiles, G. T. McKee & C. G. Dean (eds.), Evolving Knowledge in Natural Science and Artificial Intelligence. London: Pitman Publishing. pp. 231-49.
    Physical reality is all the reality we have, and so physical theory in the standard sense is all the ontology we need. This, at least, was an assumption taken almost universally for granted by the advocates of exact philosophy for much of the present century. Every event, it was held, is a physical event, and all structure in reality is physical structure. The grip of this assumption has perhaps been gradually weakened in recent years as far as the sciences of (...)

    What Is the Validity Domain of Einstein’s Equations? Distributional Solutions Over Singularities and Topological Links in Geometrodynamics.Elias Zafiris - 2016 - 100 Years of Chronogeometrodynamics: The Status of the Einstein's Theory of Gravitation in Its Centennial Year.
    The existence of singularities alerts that one of the highest priorities of a centennial perspective on general relativity should be a careful re-thinking of the validity domain of Einstein’s field equations. We address the problem of constructing distinguishable extensions of the smooth spacetime manifold model, which can incorporate singularities, while retaining the form of the field equations. The sheaf-theoretic formulation of this problem is tantamount to extending the algebra sheaf of smooth functions to a distribution-like algebra sheaf in which the (...)

    A New Reading of Aritsotle's "Hyle".Dennis F. Polis - 1991 - Modern Schoolman 68 (3):225-244.
    Aritsotle's hyle is contrasted with Plato's chora and Aquinas's prima materia. It is argued that Plato and Aristotle developed their concepts in response to very different needs, and that Aquinas's theory reflects a conflation of their views by Neoplatonic commentators. Hyle is shown to be an active potential to a determinate form in contrast to Aquinas's prima materia, which is a purely indeterminate passive potential. This gives a point of attachment in Aristotle's philosophy of nature for the later notion of (...)

    Journey of Physics between Continuity and Discontinuity مسيرة الفيزياء بين مقولتي الاتصال والانفصال.Salah Osman - 1998 - In Continuity and Infinity between Science and Philosophy. pp. 151 - 241.
    تجلت المعالجة الفيزيائية المعاصرة لموضوع الاتصال في نظريتين كبريتين تقاسمتا البحث في الظواهر الطبيعية منذ بداية القرن العشرين: إحداهما نظريــة النسبية (الخاصـة والعامـة)، والأخرى نظرية الكم. وبينما تُعيد النسبية الخاصة صياغة القوانين الأساسية للحركة على نحو أدق مما قدمه نيوتن، تتجه النسبية العامة إلى تعليل خواص المادة على النطاق الواسع، أي على مستوى الكون الأكبر، حيث النجوم والكواكب وحركاتها التجاذبية. أما نظرية الكمّ فتًعلل خواص المادة على النطاق الضيق جدًا، أي على مستوى الكون الذري. وليس هناك فيما يبدو أية رابطة (...)

    Mie's Theories of Matter and Gravitation.Chris Smeenk - 2007 - In Jürgen Renn (ed.), The Genesis of General Relativity. Boston: Springer. pp. 1543-1553.
    Unifying physics by describing a variety of interactions – or even all interactions – within a common framework has long been an alluring goal for physicists. One of the most ambitious attempts at unification was made in the 1910s by Gustav Mie. Mie aimed to derive electromagnetism, gravitation, and aspects of the emerging quantum theory from a single variational principle and a well-chosen Lagrangian. Mie’s main innovation was to consider nonlinear field equations to allow for stable particle-like solutions (now called (...)

    ARE DARK MATTER AND DARK ENERGY OPPOSITE EFFECTS OF THE QUANTUM VACUUM?Alfonso Leon Guillen Gomez - manuscript
    In the standard model of cosmology, λCDM, were introduced to explain the anomalies of the orbital velocities of galaxies in clusters highest according estimated by General Relativity the dark matter and the accelerated expansion of the universe the dark energy. The model λCDM is based in the equations of the General Relativity that of the total mass-energy of the universe assigns 4.9% to matter (including only baryonic matter), 26.8%, to dark matter and 68.3% to dark energy adjusted according observed in (...)

    Neural Plasticity and the Limits of Scientific Knowledge.Pasha Parpia - 2015 - Dissertation, University of Sussex
    Western science claims to provide unique, objective information about the world. This is supported by the observation that peoples across cultures will agree upon a common description of the physical world. Further, the use of scientific instruments and mathematics is claimed to enable the objectification of science. In this work, carried out by reviewing the scientific literature, the above claims are disputed systematically by evaluating the definition of physical reality and the scientific method, showing that empiricism relies ultimately upon the (...)

    Space and the Extension of Power in Leibniz’ Monadic Metaphysics.Edward Slowik - 2015 - History of Philosophy Quarterly 32 (3):253-270.
    This paper attempts to resolve the puzzle associated with the non-spatiality of monads by investigating the possibility that Leibniz employed a version of the extension of power doctrine, a Scholastic concept that explains the relationship between immaterial and material beings. As will be demonstrated, not only does the extension of power doctrine lead to a better understanding of Leibniz’ reasons for claiming that monads are non-spatial, but it also supports those interpretations of Leibniz’ metaphysics that accepts the real extension of (...)

    Perfect Solidity: Natural Laws and the Problem of Matter in Descartes' Universe.Edward Slowik - 1996 - History of Philosophy Quarterly 13 (2):187 - 204.
    In the Principles of Philosophy, Descartes attempts to explicate the well-known phenomena of varying bodily size through an appeal to the concept of "solidity," a notion that roughly corresponds to our present-day concept of density. Descartes' interest in these issues can be partially traced to the need to define clearly the role of matter in his natural laws, a problem particularly acute for the application of his conservation principle. Specifically, since Descartes insists that a body's "quantity of motion," defined as (...)

    Hobbes and the Phantasm of Space.Edward Slowik - 2014 - Hobbes Studies 27 (1):61-79.
    This essay examines Hobbes’ philosophy of space, with emphasis placed on the variety of interpretations that his concept of imaginary space has elicited from commentators. The process by which the idea of space is acquired from experience, as well as the role of nominalism, will be offered as important factors in tracking down the elusive content of Hobbes’ conception of imaginary space.

    Euler, Newton, and Foundations for Mechanics.Marius Stan - 2017 - In Chris Smeenk & Eric Schliesser (eds.), The Oxford Handbook of Newton. Oxford University Press. pp. 1-22.
    This chapter looks at Euler’s relation to Newton, and at his role in the rise of ‘Newtonian’ mechanics. It aims to give a sense of Newton’s complicated legacy for Enlightenment science, and to raise awareness that some key ‘Newtonian’ results really come from Euler.
