    Business as usual and Ovsyankina effect.Andrej Poleev - 2020 - Enzymes 18.
    Die Wiederaufnahme unterbrochener Handlungen nach der Aussetzung der Maßnahmen zur Eindämmung von CoVid19 veranschaulicht Unveränderlichkeit und Unvergänglichkeit regressives Zustandes, in dem sich weite Teile der Bevölkerung befinden. Nach kurzer Unterbrechung kommt alles in gewöhnten Kreis alltäglicher Routine und Gedankenlosigkeit, mit denen solche Aufgaben erledigt werden. Nichts, aber gar nichts änderte sich nach dem Unglück, das eigentlich, wie in meisten solchen Fällen, die Gelegenheit bietet, über sich selbst und die Welt nachzudenken.

    Discovering Reality by Studying the System of Freedom and Proving Its Equivalence with the Universe.Kai Jiang - 2015 - Global Journal of Pure and Applied Mathematics 11 (5):3297-3309.
    The author has established a mathematical theory about the system of freedom in which components of freedom are ruled by the largest freedom principle, explaining how one invariant reality can be equated with the dynamical universe. Freedom as a whole is the reality, and components of freedom show variable phenomena and become a dynamic system. In freedom, component equality leads to sequence equality; therefore, various sequences coexist in the system. Because there are incompatible sequences for any sequence, the interior of (...)

    真理进化论--模仿宇宙建立完美社会.Kai Jiang - 2005
    宇宙追求最小作用量,也就是最大负作用量,社会追求最大幸福,创新追求最大知识,“真理进化论”认为,这种类似不是偶然的,是由于追求之间的共性,追求方法的优越性与追求量的量纲无关,所以最好的追求方法适用于所 有追求系统。“真理进化论”认为,即使世界一无所有,只要拥有产生微小系统的自由,那么,最好的追求系统由于拥有最快的增长速度,就会获得最大的规模。增长是好的追求系统的标志,宇宙膨胀和社会发展都是增长的过程 。所有存在都可以来自于绝对的自由:只要允许产生所有微小系统,其中发展最快的系统最终必将成为宇宙。“真理进化论”在自然科学主要解决了真理的目的问题。“真理进化论”认为宇宙是目的性的,宇宙规律是追求最大负 作用量的最好方法。“真理进化论”采用目的论的方法解决所有宇宙和社会问题,将宇宙的一切规律和追求最大负作用量联系起来,将社会的一切行为和追求最大幸福联系起来,将创新行为和知识追求联系起来。在“追求科学” 中,追求目标处于核心地位,决定了系统的规律,决定了最佳追求方法。“真理进化论”也统一了人类社会的是非标准,提出建立“宇宙主义”社会:为了使人类社会成为完美社会,应该模仿完美追求系统---宇宙。法律代表 着大众共同遵守的追求方法,因此,应该将法律、道德、行政法规等统一为“一致遵守的追求方法”。法律的根本任务是鼓励符合最佳追求方法的行为,惩罚违反最佳追求方法的行为。法律的最终形式应该是完美追求方法体系, 因此,法律中的不完美部分应该有时限。模仿宇宙就可以建立完美的市场经济,例如,模仿时空建立统一市场,模仿电磁场传播让所有交易信息通过公开市场平等传播,准确发布信息等。在宇宙中,粒子有随时随地改变状态的自 由,因此,完美市场经济是彻底的自由主义经济,为了保护未来欲望的自由,要求全面推广短期合同,房屋、汽车、电器等耐用消费品应该采用短期租赁的方法;为了保障连续变化的自由,要求保护自由组合权利,尤其是劳动者 自由组合工作的权利。 .

Ainsi, une théorie doit être : complet (capable d'analyser à partir des « premiers principes » le résultat de toute expérience d'intérêt), auto-cohérent (sa prédiction pour le résultat de chaque expérience doit être unique), relativiste (à la limite où la gravité est négligée par rapport à d'autres interactions physiques, les lois non gravitationnelles de (...)

    The cosmological constant problem arises because the magnitude of vacuum energy density predicted by quantum eld theory is about 120 orders of magnitude larger than the value implied by cosmological observations of accelerating cosmic expansion. We pointed out that the fractal nature of the quantum space-time with negative Hausdor - Colombeau dimensions can resolve this tension.

It was proposed that, though the weight of modern experimentation leaves an extremely narrow and convoluted window for even a reconceptualization of a medium, all of modern physics recognizes a plethora of behaviors and attributes for (...)

    Concentrating upon applications that are most relevant to modern physics, this valuable book surveys variational principles and examines their relationship to dynamics and quantum theory. Stressing the history and theory of these mathematical concepts rather than the mechanics, the authors provide many insights into the development of quantum mechanics and present much hard-to-find material in a remarkably lucid, compact form. After summarizing the historical background from Pythagoras to Francis Bacon, Professors Yourgrau and Mandelstram cover Fermat's principle of least time, the (...)

    I argue that a slight shift in our understanding of the notion of existence is needed in order to cope with the problem of external world and the problem of mind and body. As a consequence of it being taught by "givenness" of the subjective mind, and despite its applicability in objective contexts, it should be considered a "tool" akin to qualia, rather than pertaining to a "true", objective reality. In plain language, one's supposed relation with their surroundings is known (...)

    Strong Field Gravitational Tests.Nicolae Sfetcu - manuscript
    When the density of the body becomes large enough, general relativity predicts the formation of a black hole. The neutron stars of about 1.4 solar masses and the black holes are the final stage for the evolution of the massive stars. Usually a black hole in a galaxy has played an important role in its formation and related cosmic structures. Such bodies provide an efficient mechanism for the emission of electromagnetic radiation and the formation of microquasars. Accretion can lead to (...)

    Classic Gravitational Tests of Post-Einsteinian Theories.Nicolae Sfetcu - manuscript
    Albert Einstein proposed three tests of general relativity, later named the classic tests of general relativity, in 1916: the precession of the perihelion of Mercury's orbit, sun light deflection, and the gravitational redshift of the light. For gravitational testing, the indirect effects of gravity are always used, usually particles that are influenced by gravity. In the presence of gravity, the particles move along curved geodesic lines. The sources of gravity that cause the curvature of spacetime are material bodies, depending on (...)

    Quantum Discontents, or What Is Wrong with Our Science Practice.Gennady Shkliarevsky - 2018 - Philosophies 3 (4):40-0.
    For more than eighty years, quantum theory has dominated physical science. This domination remains unchallenged to this day. Some physicists celebrate this remarkable stability. Others lament this fact and argue that QT inhibits our understanding of physical reality. They feel that numerous problems that have accumulated in physical science require stepping beyond the horizon outlined by QT. The article offers a critical examination of the foundational assumptions of QT that shape its practice. It uses two interpretations of QT as case (...)

    Tests and Anomalies of Post-Newtonian Gravitational Theories.Nicolae Sfetcu - manuscript
    Usually, the "laboratory" of gravitational tests was the celestial bodies, the astrophysical systems. But such tests are disturbed by non-gravitational effects. The most used such "laboratory" was the solar system. Recently, scientists have focused on observing binary pulsars for the verification of gravitational theories, by observing the variations of the orbital period, thus providing indirect evidence for the emission of gravitational radiation. But the experimenter cannot "arrange the lab" according to his needs, nor trigger certain events when he needs them. (...)

    The Ontic Probability Interpretation of Quantum Theory - Part II: Einstein's Incompleteness/Nonlocality Dilemma.Felix Alba-Juez - manuscript
    After pinpointing a conceptual confusion (TCC), a Reality preconception (TRP1), and a fallacious dichotomy (TFD), the famous EPR/EPRB argument for correlated ‘particles’ is studied in the light of the Ontic Probability Interpretation (TOPI) of Quantum Theory (QT). Another Reality preconception (TRP2) is identified, showing that EPR used and ignored QT predictions in a single paralogism. Employing TFD and TRP2, EPR unveiled a contradiction veiled in its premises. By removing nonlocality from QT’s Ontology by fiat, EPR preordained its incompleteness. The Petitio (...)

    A Reinterpretation of the Cosmological Vacuum.Thomas Schürmann - manuscript
    In this paper, we make a proposal for addressing the cosmological constant problem. Our approach will be based on a reinterpretation of two non-standard de Sitter solutions given by the Einstein vacuum equations with Λ>0. As a first result, we derive an uncertainty principle for both variants of the de Sitter space (Theorem). Subsequently, a decomposition of the cosmological constant in a pair of time-dependent pieces is introduced (Corollary). The time-dependence of the corresponding energy and dark energy density is discussed (...)

    On the Uncertainty Principle in Rindler and Friedmann Spacetimes.Thomas Schürmann - 2020 - European Physical Journal C 80.
    We revise the extended uncertainty relations for the Rindler and Friedmann spacetimes recently discussed by Dabrowski and Wagner in [9]. We reveal these results to be coordinate dependent expressions of the invariant uncertainty relations recently derived for general 3-dimensional spaces of constant curvature in [10]. Moreover, we show that the non-zero minimum standard deviations of the momentum in [9] are just artifacts caused by an unfavorable choice of coordinate systems which can be removed by standard arguments of geodesic completion.

    Uncertainty Principle on 3-Dimensional Manifolds of Constant Curvature.Thomas Schürmann - 2018 - Foundations of Physics 48 (6):716-725.
    We consider the Heisenberg uncertainty principle of position and momentum in 3-dimensional spaces of constant curvature K. The uncertainty of position is defined coordinate independent by the geodesic radius of spherical domains in which the particle is localized after a von Neumann–Lüders projection. By applying mathematical standard results from spectral analysis on manifolds, we obtain the largest lower bound of the momentum deviation in terms of the geodesic radius and K. For hyperbolic spaces, we also obtain a global lower bound (...)

We find out that σ p =∞ is not an exception but a rather typical case. A necessary and sufficient condition for σ p <∞ is given. Finally, the inequality σ p Δx≥π ℏ is derived and it is shown that this bound cannot be improved.

    The golden ratio is found to be related to the fine-structure constant, which determines the strength of the electromagnetic interaction. The golden ratio and classical harmonic proportions with quartic equations give an approximate value for the inverse fine-structure constant the same as that discovered previously in the geometry of the hydrogen atom. With the former golden ratio results, relationships are also shown between the four fundamental forces of nature: electromagnetism, the weak force, the strong force, and the force of gravitation.

    Why Is There Something, Rather Than Nothing?Sean M. Carroll - forthcoming - In Eleanor Knox & Alastair Wilson (eds.), Routledge Companion to the Philosophy of Physics.
    It seems natural to ask why the universe exists at all. Modern physics suggests that the universe can exist all by itself as a self-contained system, without anything external to create or sustain it. But there might not be an absolute answer to why it exists. I argue that any attempt to account for the existence of something rather than nothing must ultimately bottom out in a set of brute facts; the universe simply is, without ultimate cause or explanation.

    The purpose of this note is to show how an 'AB-series' interpretation of time, given in a companion paper, leads, surprisingly, directly to the physicists' important AdS5 geometry. This is not a theory of 2 time dimensions. Rather, it is a theory of 1 time dimension that has both B-series and A-series characteristics. -/- To summarize the result, a spacetime in terms of 1. the earlier-to-later aspect of time, and 2. the related future-present-past aspect of time, and 3. 3-d space, (...)

    Was Polchinski Wrong? Colombeau Distributional Rindler Space-Time with Distributional Levi-Cività Connection Induced Vacuum Dominance. Unruh Effect Revisited.Jaykov Foukzon - 2018 - Journal of High Energy Physics, Gravitation and Cosmology 2 (4):361-440.
    The vacuum energy density of free scalar quantum field Φ in a Rindler distributional space-time with distributional Levi-Cività connection is considered. It has been widely believed that, except in very extreme situations, the influence of acceleration on quantum fields should amount to just small, sub-dominant contributions. Here we argue that this belief is wrong by showing that in a Rindler distributional background space-time with distributional Levi-Cività connection the vacuum energy of free quantum fields is forced, by the very same background (...)

    The Solution Cosmological Constant Problem.Jaykov Foukzon - 2019 - Journal of Modern Physics 10 (7):729-794.
    The cosmological constant problem arises because the magnitude of vacuum energy density predicted by the Quantum Field Theory is about 120 orders of magnitude larger then the value implied by cosmological observations of accelerating cosmic expansion. We pointed out that the fractal nature of the quantum space-time with negative Hausdorff-Colombeau dimensions can resolve this tension. The canonical Quantum Field Theory is widely believed to break down at some fundamental high-energy cutoff ∗ Λ and therefore the quantum fluctuations in the vacuum (...)

    Gravitational Singularities.Nicolae Sfetcu - manuscript
    Gravitational singularities in general relativity are spacetime locations where the gravitational field becomes infinite. Scalar invariant curves of spacetime include a measure of matter density. Some physicists and philosophers believe that because the density of matter tends to become infinite in singularity, spacetime laws are no longer valid there. A gravitational singularity almost universally accepted in astrophysics and cosmology as the earliest state of the universe, is the Big Bang. In this case also, the known laws of physics are no (...)

    Holographic Visions: A History of New Science.Sean F. Johnston - 2006 - Oxford University Press UK.
    Holography exploded on the scientific world in 1964, but its slow fuse had been burning much longer. Over the next four decades, the echoes of that explosion reached scientists, engineers, artists and popular culture. Emerging from classified military research, holography evolved to represent the power of post-war physics, an aesthetic union of art and science, the countercultural meanderings of holism, a cottage industry for waves of would-be entrepreneurs and a fertile plot device for science fiction. New working cultures sprang up (...)

    Perspectives On Organisms: Biological Time, Symmetries And Singularities.Maël Montévil & Giuseppe Longo - 2014 - Springer.
    This authored monograph introduces a genuinely theoretical approach to biology. Starting point is the investigation of empirical biological scaling including their variability, which is found in the literature, e.g. allometric relationships, fractals, etc. The book then analyzes two different aspects of biological time: first, a supplementary temporal dimension to accommodate proper biological rhythms; secondly, the concepts of protension and retention as a means of local organization of time in living organisms. Moreover, the book investigates the role of symmetry in biology, (...)

    The Road From Reality: A Purely Mathematical Proof of the Existence of the Observable Universe.Alexandre Harvey Tremblay - manuscript
    This manuscript describes the most fundamental description of reality I believe to be possible. Specifically, my proposal is sufficiently powerful to inherit the coveted indubitable property of the Cartesian universal doubt method then to carry it forward such that the structure of reality, in the form of a model of the observable universe including the laws of physics, is inherited indubitably from pure reason, whilst avoiding the pitfall at the mind-body problem. The strategy is to construct a purely mathematical model (...)

    Explanation in Physics: Explanation in Physical Theory: Peter Clark.Peter Clark - 1990 - Royal Institute of Philosophy Supplement 27:155-175.
    The corpus of physical theory is a paradigm of knowledge. The evolution of modern physical theory constitutes the clearest exemplar of the growth of knowledge. If the development of physical theory does not constitute an example of progress and growth in what we know about the Universe nothing does. So anyone interested in the theory of knowledge must be interested consequently in the evolution and content of physical theory. Crucial to the conception of physics as a paradigm of knowledge is (...)
