  1. A Complex Number Notation of Nature of Time: An Ancient Indian Insight.R. B. Varanasi Varanasi Varanasi Ramabrahmam, Ramabrahmam Varanasi, V. Ramabrahmam - 2013 - In Varanasi Ramabrahmam Ramabrahmam Varanasi V. Ramabrahmam R. B. Varanasi Varanasi (ed.), Proceedings of 5th International Conference on Vedic Sciences on “Applications and Challenges in Vedic / Ancient Indian Mathematics". Veda Vijnaana Sudha. pp. 386-399.
    The nature of time is perceived by intellectuals variedly. An attempt is made in this paper to reconcile such varied views in the light of the Upanishads and related Indian spiritual and philosophical texts. The complex analysis of modern mathematics is used to represent the nature and presentation physical and psychological times so differentiated. Also the relation between time and energy is probed using uncertainty relations, forms of energy and phases of matter.

    Modern confucian synthesis of qualitative and quantitative knowledge: Xiong shili.Jana S. Rošker - 2009 - Journal of Chinese Philosophy 36 (3):376-390.
    Xiong was the originator and founder of Modern Confucianism (xin ruxue ) as well as one of the first Chinese philosophers, who developed his own system of thought, which was based upon classical Confucian concepts and, at the same time, adjusted to the conditions of the New Era. His contribution to the development of modern Chinese philosophy can also be demonstrated in a much broader, general sense. Xiong Shili, namely, also represents one of the first theoretically qualified intellectuals of his (...)

    Quantum information and locality.Dennis Dieks - 2017 - In Olimpia Lombardi, Sebastian Fortin, Federico Holik & Cristian López (eds.), What is Quantum Information? New York, NY: CUP.
    The surprising aspects of quantum information are due to two distinctly non-classical features of the quantum world: first, different quantum states need not be orthogonal and, second, quantum states may be entangled. Non-orthogonality leads to the blurring of classical distinctions. On the other hand, entanglement leads via non-locality to teleportation and other ``entanglement-assisted'' forms of communication that go beyond what is classically possible. In this article we attempt to understand these new possibilities via an analysis of the significance of entanglement (...)

    Qualitative and Quantitative Parameters of the Execution of Foreign Policy in the Lithuanian Constitution.Egidijus Jarašiūnas - 2012 - Jurisprudencija: Mokslo darbu žurnalas 19 (3):923-953.
    The present article analyses the qualitative and quantitative parameters of the execution of foreign policy in the Constitution of the Republic of Lithuania. It should be noted that the matters of foreign policy were on the brink of constitutional regulation for a long time. The powers of institutions of the state in the field of foreign relations were established laconically by the Constitutions of first and second “waves” of establishment of constitutionalism. It was argued that the choices of (...)

    Qualitative and Quantitative Examples of Natural and Artificial Phenomena.Antoni Hernández-Fernández - 2021 - Biosemiotics 14 (2):377-390.
    The dichotomy between the qualitative and the quantitative has been a classic throughout the history of science. As will be seen, this dichotomy permeates all ontological levels of reality. In this work, phenomenological examples potentially related to semiosis are presented at the different levels established by Mario Bunge and Josep Ferrater Mora, contrasting the qualitative categorizations with the quantifiable physical reality. Likewise, the need to continue in the quantification of the biosemiotic and linguistic studies will be presented, (...)

  7. The Structural Metaphysics of Quantum Theory and General Relativity.Vincent Lam & Michael Esfeld - 2012 - Journal for General Philosophy of Science / Zeitschrift für Allgemeine Wissenschaftstheorie 43 (2):243-258.
    The paper compares ontic structural realism in quantum physics with ontic structural realism about space–time. We contend that both quantum theory and general relativity theory support a common, contentful metaphysics of ontic structural realism. After recalling the main claim of ontic structural realism and its physical support, we point out that both in the domain of quantum theory and in the domain of general relativity theory, there are objects whose essential ways of being are certain relations so that these objects (...)

    Qualitative and quantitative analysis for political studies: Trilateral science, experimental methodology and grounded theory.Adolfo Eslava - 2014 - Cinta de Moebio 51:111-126.
    The paper discuss the application of qualitative and quantitative techniques in political studies. It describes the classical proposal of Johan Galtung, known as trilateral science, which invites to the permanent contrast to confirm, validate and accept facts and ideas; then it explores Grounded Theory as a mechanism to achieve and explore data in order to identify a possible dialogue with experimental methodology. Finally, it shows social capital as a case study to demonstrate the relevance of multi-methodological applications. El (...)

    On Cultural Environment and Cultural Environment in Vietnam.Quy Ho Si - 2008 - Proceedings of the Xxii World Congress of Philosophy 20:101-120.
    The problem of cultural environment is not new, but the use of the theory on cultural environment is clearly a new approach to the consideration of familiar questions. That is the problem, is it true that the context has become such that man, as an individual, is becoming increasingly smaller, weaker, more tightly defined and restrained, in a society which is steadily developing in the direction of becoming multi-dimensional and ambiguous with its “logic of imposition”? As for the cultural environment, (...)

    Swedenborg and Kant.C. H. Os - 1937 - Synthese 2 (1):514 - 526.
    The relation between Emanuel Swedenborg and Immanuel Kant has been the subject of many discussions. The chief aim of this paper is not to elucidate this question from an historical point of view, but to compare the teachings of the two thinkers, as those teachings have come to us. Kant's "Träme eines Geistersehers" embodies a very unfavourable opinion about Swedenborg. It is a curious circumstance, that this judgement is not based on decisive arguments. On the contrary, Swedenborg's fundamental doctrines about (...)

  11. Towards unified field theory: Quantitative differences and qualitative sameness.Mael A. Melvin - 1982 - Synthese 50 (3):359 - 397.
    A survey is given of the concepts of interaction (force) and matter, i.e., of process and substance. The development of these concepts, first in antiquity, then in early modern times, and finally in the contemporary system of quantum field theory is described. After a summary of the basic phenomenological attributes (coupling strengths, symmetry quantities, charges), the common ground of concepts of quantum field theory for both interactions and matter entities is discussed. Then attention is focused on the gauge principle (...)

    Qualitative versus quantitative representation: a non-standard analysis of the sorites paradox.Yair Itzhaki - 2021 - Linguistics and Philosophy 44 (5):1013-1044.
    This paper presents an analysis of the sorites paradox for collective nouns and gradable adjectives within the framework of classical logic. The paradox is explained by distinguishing between qualitative and quantitative representations. This distinction is formally represented by the use of a different mathematical model for each type of representation. Quantitative representations induce Archimedean models, but qualitative representations induce non-Archimedean models. By using a non-standard model of \ called \, which contains infinite and infinitesimal numbers, the (...)

  13. Both Classical & Quantum Information; Both Bit & Qubit: Both Physical & Transcendental Time.Vasil Penchev - 2021 - Philosophy of Science eJournal (Elsevier: SSRN) 14 (22):1-24.
    Information can be considered as the most fundamental, philosophical, physical and mathematical concept originating from the totality by means of physical and mathematical transcendentalism (the counterpart of philosophical transcendentalism). Classical and quantum information, particularly by their units, bit and qubit, correspond and unify the finite and infinite. As classical information is relevant to finite series and sets, as quantum information, to infinite ones. A fundamental joint relativity of the finite and infinite, of the external and internal is to be investigated. (...)

  14. The relation between the time of psychology and the time of physics part I.H. A. C. Dobbs - 1951 - British Journal for the Philosophy of Science 2 (6):122-141.
    THIS paper seeks to elucidate the phenomenon known in psychology as 'the specious present,' by postulating a two-dimensional theory of the extensional aspects of time. On this theory, the usual logical and psychological difficulties, encountered in current accounts of this phenomenon, can be resolved. For, when there are two dimensions of time, the same event may be without extension in one of these dimensions ('transition-time'), while it is nevertheless finitely extended in the other of these dimensions ('phase-time'); so that in (...)

    Insufficient Reason and Entropy in Quantum Theory.Ariel Caticha - 2000 - Foundations of Physics 30 (2):227-251.
    The objective of the consistent-amplitude approach to quantum theory has been to justify the mathematical formalism on the basis of three main assumptions: the first defines the subject matter, the second introduces amplitudes as the tools for quantitative reasoning, and the third is an interpretative rule that provides the link to the prediction of experimental outcomes. In this work we introduce a natural and compelling fourth assumption: if there is no reason to prefer one region of the configuration space (...)

    Completing the Physical Representation of Quantum Algorithms Provides a Quantitative Explanation of Their Computational Speedup.Giuseppe Castagnoli - 2018 - Foundations of Physics 48 (3):333-354.
    The usual representation of quantum algorithms, limited to the process of solving the problem, is physically incomplete. We complete it in three steps: extending the representation to the process of setting the problem, relativizing the extended representation to the problem solver to whom the problem setting must be concealed, and symmetrizing the relativized representation for time reversal to represent the reversibility of the underlying physical process. The third steps projects the input state of the representation, where the problem solver is (...)

    Time Symmetric Quantum Mechanics and Causal Classical Physics?Fritz W. Bopp - 2017 - Foundations of Physics 47 (4):490-504.
    A two boundary quantum mechanics without time ordered causal structure is advocated as consistent theory. The apparent causal structure of usual “near future” macroscopic phenomena is attributed to a cosmological asymmetry and to rules governing the transition between microscopic to macroscopic observations. Our interest is a heuristic understanding of the resulting macroscopic physics.

    Quantum mechanics and the direction of time.H. Hasegawa, T. Petrosky, I. Prigogine & S. Tasaki - 1991 - Foundations of Physics 21 (3):263-281.
    In recent papers the authors have discussed the dynamical properties of “large Poincaré systems” (LPS), that is, nonintegrable systems with a continuous spectrum (both classical and quantum). An interesting example of LPS is given by the Friedrichs model of field theory. As is well known, perturbation methods analytic in the coupling constant diverge because of resonant denominators. We show that this Poincaré “catastrophe” can be eliminated by a natural time ordering of the dynamical states. We obtain then a dynamical theory (...)

    This book brings together papers from a conference that took place in the city of L'Aquila, 4–6 April 2019, to commemorate the 10th anniversary of the earthquake that struck on 6 April 2009. Philosophers and scientists from diverse fields of research debated the problem that, on 6 April 1922, divided Einstein and Bergson: the nature of time. For Einstein, scientific time is the only time that matters and the only time we can rely on. Bergson, however, believes that scientific time (...)

    How can we be certain of what a physics theory is talking about and, at the same time, not have a clue what the theory is about? Yet, this seemingly nonsensical question lurks in the background since the advent of quantum physics and is intimately entangled with the cluster of issues constituting the raw material for philosophers of science striving to negotiate the so-called classical to quantum divide.The discourse of theoretical physics unfolds on two levels: the experimental and the mathematical.

  22. The quantitative epistemological content of Bohr's correspondence principle.Arthur Komar - 1970 - Synthese 21 (1):83 - 92.
    The basic dynamical quantities of classical mechanics, such as position, linear momentum, angular momentum and energy, obtain their fundamental epistomological content by means of their intimate relationship to the symmetries of the space-time manifold which is the arena of physics. The program of canonical quantization can be understood as a two stage process. The first stage is Bohr's Correspondence Principle, whereby the basic dynamical quantities of the quantum theory are required to retain precisely the same relationship to the symmetries of (...)

    Synchronization and Fundamental Time: A Connection Between Relativity and Quantum Mechanics.Matteo Luca Ruggiero - 2023 - Foundations of Physics 53 (5):1-9.
    An interesting connection between special relativity and quantum mechanics was put forward by Louis de Broglie, about 60 years ago, who focused on the link between synchronization in a rotating frame and the quantization of the angular momentum. Here we generalise his approach to curved spacetime, using the gravitoelectromagnetic analogy, which can be applied to describe the weak gravitational field around rotating sources, and give a new interpretation of the results.

    Quantum Systems under Gravitational Time Dilation.Magdalena Zych - 2017 - Cham: Imprint: Springer.
    This thesis introduces a new theoretical tool to explore the notion of time and temporal order in quantum mechanics: the relativistic quantum "clock" framework. It proposes novel thought experiments showing that proper time can display quantum features, e.g. when a "clock" runs different proper times in superposition. The resulting new physical effects can be tested in near-future laboratory experiments (with atoms, molecules and photons as "clocks"). The notion of time holds the key to the regime where quantum theory and (...)

  26. Time, quantum mechanics, and decoherence.Simon Saunders - 1995 - Synthese 102 (2):235 - 266.
    State-reduction and the notion of actuality are compared to passage through time and the notion of the present; already in classical relativity the latter give rise to difficulties. The solution proposed here is to treat both tense and value-definiteness as relational properties or facts as relations; likewise the notions of change and probability. In both cases essential characteristics are absent: temporal relations are tenselessly true; probabilistic relations are deterministically true. The basic ideas go back to Everett, although the technical development (...)

    It is argued that seemingly “merely technical” issues about the existence and uniqueness of self-adjoint extensions of symmetric operators in quantum mechanics have interesting implications for foundations problems in classical and quantum physics. For example, pursuing these technical issues reveals a sense in which quantum mechanics can cure some of the forms of indeterminism that crop up in classical mechanics; and at the same time it reveals the possibility of a form of indeterminism in quantum mechanics that is quite distinct (...)

    Connecting Blackbody Radiation, Relativity, and Discrete Charge in Classical Electrodynamics.Timothy H. Boyer - 2007 - Foundations of Physics 37 (7):999-1026.
    It is suggested that an understanding of blackbody radiation within classical physics requires the presence of classical electromagnetic zero-point radiation, the restriction to relativistic (Coulomb) scattering systems, and the use of discrete charge. The contrasting scaling properties of nonrelativistic classical mechanics and classical electrodynamics are noted, and it is emphasized that the solutions of classical electrodynamics found in nature involve constants which connect together the scales of length, time, and energy. Indeed, there are analogies between the electrostatic forces for groups (...)

    Quantum Interference and Many Worlds: A New Family of Classical Analogies. [REVIEW]M. J. Rave - 2011 - Foundations of Physics 41 (8):1318-1330.
    We present a new way of constructing classical analogies of quantum interference. These analogies share one common factor: they treat closed loops as fundamental entities. Such analogies can be used to understand the difference between quantum and classical probability; they can also be used to illuminate the many worlds interpretation of quantum mechanics. An examination of these analogies suggests that closed loops (particularly closed loops in time) may have special significance in interpretations of quantum interference, because they allow probabilities to (...)

    Quantum Chaos and Semiclassical Mechanics.Robert Batterman - 1992 - PSA: Proceedings of the Biennial Meeting of the Philosophy of Science Association 1992:50-65.
    This paper discusses the problem of finding and defining chaos in quantum mechanics. While chaotic time evolution appears to be ubiquitous in classical mechanics, it is apparently absent in quantum mechanics in part because for a bound, isolated quantum system, the evolution of its state is multiply periodic. This has led a number of investigators to search for semiclassical signatures of chaos. Here I am concerned with the status of semiclassical mechanics as a distinct third theory of the asymptotic domain (...)

    Semi-Classical Limit and Minimum Decoherence in the Conditional Probability Interpretation of Quantum Mechanics.Vincent Corbin & Neil J. Cornish - 2009 - Foundations of Physics 39 (5):474-485.
    The Conditional Probability Interpretation of Quantum Mechanics replaces the abstract notion of time used in standard Quantum Mechanics by the time that can be read off from a physical clock. The use of physical clocks leads to apparent non-unitary and decoherence. Here we show that a close approximation to standard Quantum Mechanics can be recovered from conditional Quantum Mechanics for semi-classical clocks, and we use these clocks to compute the minimum decoherence predicted by the Conditional Probability Interpretation.

    Time, along with concepts as space and matter, is bound to be a central concept of any physical theory. The chapter first discusses how time is treated similarly in quantum and classical theories. It then provides a few references on time‐reversal. The chapter discusses three chosen authors' (Paul Busch, Jan Hilgevoord and Jos Uffink) clarifications of uncertainty principles in general. Next, the chapter follows Busch in distinguishing three roles for time in quantum physics. They are external time, intrinsic time and (...)

    Open Systems’ Density Matrix Properties in a Time Coarsened Formalism.Robert Englman & Asher Yahalom - 2015 - Foundations of Physics 45 (6):673-690.
    The concept of time-coarsened density matrix for open systems has frequently featured in equilibrium and non-equilibrium statistical mechanics, without being probed as to the detailed consequences of the time averaging procedure. In this work we introduce and prove the need for a selective and non-uniform time-sampling, whose form depends on the properties of the bath. It is also applicable when an open microscopic sub-system is coupled to another finite system. By use of a time-periodic minimal coupling model between these two (...)

    Two radically different views about time are possible. According to the first, the universe is three dimensional. It has a past and a future, but that does not mean it is spread out in time as it is spread out in the three dimensions of space. This view requires that there is an unambiguous, absolute, cosmic-wide "now" at each instant. According to the second view about time, the universe is four dimensional. It is spread out in both space and time (...)

    In time and over time.Tim Smithers - 1998 - Behavioral and Brain Sciences 21 (5):651-652.
    Van Gelder's clear distinction between the quantitative nature of dynamical systems and the nonquantitative nature of computational processes provides a firm basis for distinguishing between processes that happen in time and processes that happen over time. Symbolic reasoning, the presumed basis of intelligent behavior in robots, happens over time. However, the movements and actions that robots must make to behave intelligently, happen in time. Attempting to connect the two, as classical artificial intelligence and robotics have presumed to be necessary, (...)

    Quantum Reality and Theory of Śūnya.Siddheshwar Rameshwar Bhatt (ed.) - 2019 - Springer.
    The book deals with expounding the nature of Reality as it is understood in contemporary times in Quantum Physics. It also explains the classical Indian theory of Śūnya in its diverse facets. Thereafter it undertakes comparison between the two which is an area of great topical interest. It is a cross-disciplinary study by erudite Indian and western scholars between traditional Indian knowledge system and contemporary researches in Physical sciences. It points out how the theory of ‘Śūnyatā has many seminal (...)

    Classical and Quantum Mechanics via Supermetrics in Time.E. Gozzi - 2010 - Foundations of Physics 40 (7):795-806.
    Koopman-von Neumann in the 30’s gave an operatorial formulation of Classical Mechanics. It was shown later on that this formulation could also be written in a path-integral form. We will label this functional approach as CPI (for classical path-integral) to distinguish it from the quantum mechanical one, which we will indicate with QPI. In the CPI two Grassmannian partners of time make their natural appearance and in this manner time becomes something like a three dimensional supermanifold. Next we introduce a (...)

    Time as a Geometric Concept Involving Angular Relations in Classical Mechanics and Quantum Mechanics.Juan Eduardo Reluz Machicote - 2010 - Foundations of Physics 40 (11):1744-1778.
    The goal of this paper is to introduce the notion of a four-dimensional time in classical mechanics and in quantum mechanics as a natural concept related with the angular momentum. The four-dimensional time is a consequence of the geometrical relation in the particle in a given plane defined by the angular momentum. A quaternion is the mathematical entity that gives the correct direction to the four-dimensional time.Taking into account the four-dimensional time as a vectorial quaternionic idea, we develop a set (...)

    Time and the Foundations of Quantum Mechanics.Thomas Pashby - unknown
    Quantum mechanics has provided philosophers of science with many counterintuitive insights and interpretive puzzles, but little has been written about the role that time plays in the theory. One reason for this is the celebrated argument of Wolfgang Pauli against the inclusion of time as an observable of the theory, which has been seen as a demonstration that time may only enter the theory as a classical parameter. Against this orthodoxy I argue that there are good reasons to expect certain (...)

  46. Quantum Gravity and Phenomenological Philosophy.Steven M. Rosen - 2008 - Foundations of Physics 38 (6):556-582.
    The central thesis of this paper is that contemporary theoretical physics is grounded in philosophical presuppositions that make it difficult to effectively address the problems of subject-object interaction and discontinuity inherent to quantum gravity. The core objectivist assumption implicit in relativity theory and quantum mechanics is uncovered and we see that, in string theory, this assumption leads into contradiction. To address this challenge, a new philosophical foundation is proposed based on the phenomenology of Maurice Merleau-Ponty and Martin Heidegger. Then, through (...)

  47. Quantum Mechanics and the Metrics of General Relativity.Paul O’Hara - 2005 - Foundations of Physics 35 (9):1563-1584.
    A one-to-one correspondence is established between linearized space-time metrics of general relativity and the wave equations of quantum mechanics. Also, the key role of boundary conditions in distinguishing quantum mechanics from classical mechanics, will emerge naturally from the procedure. Finally, we will find that the methodology will enable us to introduce not only test charges but also test masses by means of gauges.

    Do `classical' space and time confer identity to quantum particles?Décio Krause - unknown
    Non-relativistic quantum mechanics is grounded on ‘classical’ space and time. The mathematical description of these con- cepts entails that any two spatially separated objects are necessarily dif- ferent, which implies that they are discernible — we say that the space is T2, or "Hausdorff". But quantum systems, in the most interesting cases, some- times need to be taken as indiscernible, so that there is no way to tell which system is which, and this holds even in the case of (...)

  49. Quantity in Quantum Mechanics and the Quantity of Quantum Information.Vasil Penchev - 2021 - Philosophy of Science eJournal (Elsevier: SSRN) 14 (47):1-10.
    The paper interprets the concept “operator in the separable complex Hilbert space” (particalry, “Hermitian operator” as “quantity” is defined in the “classical” quantum mechanics) by that of “quantum information”. As far as wave function is the characteristic function of the probability (density) distribution for all possible values of a certain quantity to be measured, the definition of quantity in quantum mechanics means any unitary change of the probability (density) distribution. It can be represented as a particular case of “unitary” qubits. (...)

  50. Quantum mechanics and the equivalence principle.Paul Davies - manuscript
    A quantum particle moving in a gravitational field may penetrate the classically forbidden region of the gravitational potential. This raises the question of whether the time of flight of a quantum particle in a gravitational field might deviate systematically from that of a classical particle due to tunnelling delay, representing a violation of the weak equivalence principle. I investigate this using a model quantum clock to measure the time of flight of a quantum particle in a uniform gravitational field, and (...)
