This volume is the first systematic presentation of the work of Albert Einstein, comprising fourteen essays by leading historians and philosophers of science that introduce readers to his work. Following an introduction that places Einstein's work in the context of his life and times, the book opens with essays on the papers of Einstein's 'miracle year', 1905, covering Brownian motion, light quanta, and special relativity, as well as his contributions to early quantum theory and the opposition to (...) his light quantum hypothesis. Further essays relate Einstein's path to the general theory of relativity (1915) and the beginnings of two fields it spawned, relativistic cosmology and gravitational waves. Essays on Einstein's later years examine his unified field theory program and his critique of quantum mechanics. The closing essays explore the relation between Einstein's work and twentieth-century philosophy, as well as his political writings. (shrink)

In this paper, I accomplish a conceptual task and a historical task. The conceptual task is to argue that (1) Einstein’s Principle of Separability (henceforth “separability”) is not a supervenience principle and that (2) separability and entanglement are compatible. I support (1) by showing that the conclusion of Einstein’s incompleteness argument would still follow even if one assumes that the state of a composite system does not supervene on the states of the subsystems, and by showing that what (...) Einstein says in “Quantum Mechanics and Reality” (1948) strongly suggests that separability is not a principle about how subsystem states relate to the state of composite systems. I support (2) by showing that if separability was incompatible with entanglement, then Einstein’s argument would be incoherent in a trivial way. Thus, by arguing for (1) and (2) I directly challenge what has been, and still is, a very common reading of separability. The historical task is to offer the first detailed review of the different ways in which separability has been defined by physicists and philosophers in the last 60 years. Among other things, such a review distinguishes three different definitions of the principle, and shows that since the 1990s and up until the present date, it became standard to take separability (as presented by Einstein) to be a supervenience principle.

This paper situates Einstein’s theory of relativity within broader networks of communication.The speed of light, explained Einstein, was an unsurpassable velocity if, and only if, it was considered in terms of »arbitrary« and »voluntary« signals. Light signals in physics belong within a broader set of signs and symbols that include communication and military signals, understood by reference to Helmholtz, Saussure, media philosophies from WWII to ‘68 (Lavelle, Ong, McLuhan) and Derrida. Once light signals in physics are considered in (...) relation to semaphore, print, telegraph, radio, computers and tape recorders, Kittler and Habermas provide us with conflicting ways for understanding science and technology, rationality and consensus.We conclude with a study of »flash and bang« in popular accounts of relativity theory to understand the role of theoretical science in the transmission of information and violence.

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 is derived by abstraction, even in the sense of extraction, from a more fundamental time. The plurality of times envisaged by the theory of Relativity does not, for him, contradict the philosophical intuition of the existence of a single time. But how do things stand today? What can we say about the relationship between the quantitative and qualitative dimensions of time in the light of contemporary science? What do quantum mechanics, biology and neuroscience teach us about the nature of time? The essays collected here take up the question that pitted Einstein against Bergson, science against philosophy, in an attempt to reverse the outcome of their monologue in two voices, with a multilogue in several voices.

The objective of this article is to demonstrate how the historical debate between materialism and idealism, in the field of Philosophy, extends, in new clothes, to the field of Quantum Physics characterized by realism and anti-realism. For this, we opted for a debate, also historical, between the realism of Albert Einstein, for whom reality exists regardless of the existence of the knowing subject, and Niels Bohr, for whom we do not have access to the ultimate reality of the matter, (...) unless conditioning it to the existence of an observer endowed with rationality, position adopted in the Interpretation of Complementarity – posture that was expanded in 1935 when Bohr assumed a “relationalist” conception, according to which the quantum state is defined by the relationship between the quantum object and the entire measuring device. This is an extremely important debate, as it further consolidates the results of nascent Quantum Mechanics, guaranteeing Bohr the leadership of the orthodoxy based on the interpretation of complementarity. Here, when dealing with Quantum Theory, we will not make any distinction between the terms Quantum Physics, Quantum Theory or Quantum Mechanics. The entire discussion will be held under the name “Quantum Theory”. Theory that tries to analyze and describe the behavior of physical systems of reduced dimensions, close to the sizes of molecules, atoms and subatomic particles. We hope that the reader will appreciate the genius of these two titans in this field of Physics when they magnificently formulate the arguments that support the object of their defenses. (shrink)

Einstein's gravitational redshift derivation in his famous 1916 paper on general relativity seems to be problematic, being mired in what looks like conceptual difficulties or at least contradictions or gaps in his exposition. Was this derivation a blunder? To answer this question, we will consider Einstein’s redshift derivations from his first one in 1907 to the 1921 derivation made in his Princeton lectures on relativity. This will enable to see the unfolding of an interdependent network of concepts and (...) heuristic derivations in which previous ideas inform and condition later developments. The resulting derivations and views on coordinates and clocks are in fact not without inconsistencies. However, we can see these difficulties as an aspect of an evolving network understood as a “work in progress”. (shrink)

In his Autobiographical Notes Einstein recognizes the importance of wonder in the cognitive process by stating that it occurs when an experience comes into conflict with a sufficiently stable world of concepts. Already in classical philosophy, wonder is considered the starting point of philosophizing as Plato highlights in Theaetetus and Aristotle in Metaphysics. To describe what the wonder consists of we will suggest a Dynamic Frames and we will use it to describe the role of wonder in the years (...) of Einstein's formation. (shrink)

The aim of this paper is to make a step towards a complete description of Special Relativity genesis and acceptance, bringing some light on the intertheoretic relations between Special Relativity and other physical theories of the day. I’ll try to demonstrate that Special Relativity and the Early Quantum Theory were created within the same programme of statistical mechanics, thermodynamics and Maxwellian electrodynamics reconciliation, i.e. elimination of the contradictions between the consequences of this theories. The approach proposed enables to explain why (...) classical mechanics and classical electrodynamics were “refuted” almost simultaneously or, in terms more suitable for the present discussion, why did the quantum and the relativistic revolutions both took place at the beginning of the 20-th century. I ‘ll argue that the quantum and the relativistic revolutions were simultaneous since they had common origin - the clash between the fundamental theories of the second half of the 19-th century that constituted the “body” of Classical Physics. The revolution’ s most dramatic turning point was Einstein’s 1905 light quantum paper, that laid the foundations of the Old Quantum Theory and influenced the fate of special theory of relativity too. Hence, the following two main interrelated theses are defended.(1)Einstein’s special relativity 1905 paper can be considered as a subprogramme of a general research programme that had its pivot in the quantum; (2) One of the reasons of Einstein’s victory over Lorentz consists in the following: special relativity theory superseded Lorentz’s theory when the general programme imposed itself, and, in so doing, made the ether concept untenable. -/- Key words: A.Einstein; H.Lorentz; I.Yu.Kobzarev; context of discovery; context of justification .

Press release. -/- The ebook entitled, Einstein’s Revolution: A Study of Theory-Unification, gives students of physics and philosophy, and general readers, an epistemological insight into the genesis of Einstein’s special relativity and its further unification with other theories, that ended well by the construction of general relativity. The book was developed by Rinat Nugayev who graduated from Kazan State University relativity department and got his M.Sci at Moscow State University department of philosophy of science and Ph.D at Moscow (...) Institute of Philosophy, Russian Academy of Science. He has forty years of philosophy of science and relativistic astrophysics teaching and research experience evincing in more than 200 papers in the scientific journals of Russia, Ukraine, Belorussia, USA, Great Britain, Germany, Spain, Italy, Sweden, Switzerland, Netherlands, Canada, Denmark, Poland, Romania, France, Greece, Japan and some other countries, and 8 monographs. Revolutions in physics all embody theoretical unification. Hence the overall aim of the present book is to unfold Einstein’s unificationist modus operandi, the hallmarks of actual Einstein’s methodology of unification that engendered his 1905 special relativity, as well as his 1915 general relativity. To achieve the object, a lucid epistemic model is exposed aimed at an analysis of the reasons for mature theory change in science (chapter1). According to the model, scientific revolutions were not due to fanciful creation of new ideas ‘ex nihilo’, but rather to the long-term processes of the reconciliation, interpenetration and intertwinement of ‘old’ research traditions preceding such breaks .Accordingly, origins of scientific revolutions lie not in a clash of fundamental theories with facts, but of “old” mature research traditions with each other, leading to contradictions that can only be attenuated in a more general theoretical approach. In chapter 2 it is contended that Einstein’s ingenious approach to special relativity creation, substantially distinguishing him from Lorentz’s and Poincaré’s invaluable impacts, turns to be a milestone of maxwellian electrodynamics, statistical mechanics and thermodynamics reconciliation design. Special relativity turns out to be grounded on Einstein’s breakthrough 1905 light quantum hypothesis. Eventually the author amends the received view on the general relativity genesis by stressing that the main reason for Einstein’s victory over the rival programmes of Abraham and Nordström was a unificationist character of Einstein’s research programme (chapter 3).

The author presents the history of gravitational waves according to Einstein, linking it to his biography and his time in order to understand it in his connection with the history of the Semites, the personality of Einstein in the handling of his conflict-generating circumstances in his relationships competition with his colleagues and in the formulation of the so-called general theory of relativity. We will fall back on the vicissitudes that Einstein experienced in the transition from his scientific (...) work to normal science as a pillar of theoretical physics. We will deal with how Einstein introduced the relativistic ether, conferring an "odor of materiality" to his geometric explanation of gravity, where undoubtedly it does not fit, but that he had to give in to the pressure that was justified by his most renowned colleagues, led by Lorentz. Einstein had to do it to stay in the queue that would lead him to the Nobel. It was thus, as developing the relativistic ether thread, in June 1916, he introduced the gravitational waves of which, in an act of personal liberation and scientific honesty, when he could, in 1938, he demonstrated how they could not exist, within the scenario of his relativity, to immediately also put an end to the relativistic ether.

Albert Einstein ist für seine Arbeiten in der Physik weltberühmt. Nur wenige wissen jedoch, dass Einstein selbst auch philosophische Arbeiten publiziert hat und seine Erkenntnisse weitreichende Folgen für die Philosophie haben. Oder haben „Raum“ und „Zeit“ nichts mit Wissen zu tun?

What are the reasons of the second scientific revolution that happened at the beginning of the XX century? Why did the new physics supersede the old one? The author tries to answer the subtle questions with a help of the epistemological model of scientific revolutions that takes into account some recent advances in philosophy, sociology and history of science. According to the model, Einstein’s Revolution took place due to resolution of deep contradictions between the basic classical research traditions: Newtonian (...) mechanics, maxwellian electrodynamics, thermodynamics and statistical mechanics. As a result, two new research programmes – relativistic and quantum- had been constructed. It was the interaction between them that formed the interdisciplinary context of Einstein’s Revolution.

Does a privileged frame of reference exist? Part of Einstein’s success consisted in eliminating Bergson’s objections to relativity theory, which were consonant with those of the most important scientists who had worked on the topic: Henri Poincaré, Hendrik Lorentz and Albert A. Michelson. In the early decades of the century, Bergson’s fame, prestige and influence surpassed that of the physicist. Once considered as one of the most renowned intellectuals of his era and an authority on the nature of time, (...) The Stanford Encyclopedia of Philosophy (2010) does not even include him under the entry of “time.” How was it possible to write off from history a figure that was once so prominent? Through an analysis of behind-the-scenes of science correspondence, this article traces the ascendance of Einstein's views of time at the expense of Bergson’s. (shrink)

This paper strengthens and defends the pluralistic implications of Einstein's successful, quantitative predictions of Brownian motion for a philosophical dispute about the nature of scientific advance that began between two prominent philosophers of science in the second half of the twentieth century (Thomas Kuhn and Paul Feyerabend). Kuhn promoted a monistic phase-model of scientific advance, according to which a paradigm driven `normal science' gives rise to its own anomalies, which then lead to a crisis and eventually a scientific revolution. (...) Feyerabend stressed the importance of pluralism for scientific progress. He rejected Kuhn's model arguing that it fails to recognize the role that alternative theories can play in identifying exactly which phenomena are anomalous in the first place. On Feyerabend's account, Einstein's predictions allow for a crucial experiment between two incommensurable theories, and are an example of an anomaly that could refute the reigning paradigm only after the development of a competitor. Using Kuhn's specification of a disciplinary matrix to illustrate the incommensurability between the two paradigms, we examine the different research strategies available in this peculiar case. On the basis of our reconstruction, we conclude by rebutting some critics of Feyerabend's argument. (shrink)

El autor presenta la historia de las ondas gravitacionales según Einstein, uniéndola a su biografía y a su época con el fin de comprenderla en su conexión con la historia de los semitas, la personalidad de Einstein en el manejo de sus circunstancias generadoras de conflicto en sus relaciones de competencia con sus colegas y en la formulación de la llamada teoría general de la relatividad. Recaeremos en las vicisitudes que vivió Einstein en el tránsito de que (...) su trabajo científico pasara a la ciencia normal como un pilar de la física teórica. Trataremos como Einstein introdujo el éter relativístico confiriéndole un “olor de materialidad” a su explicación geométrica de la gravedad, donde indudablemente, no cabe, pero que él tuvo que ceder ante la presión eso sí justificada de sus más connotados colegas, liderados por Lorentz. Einstein lo tuvo que hacer para mantenerse en la cola que lo llevaría al Nobel. Fue así, como desarrollando el hilo del éter relativista, en junio de 1916, introdujo las ondas gravitacionales de las que, en un acto de liberación personal y honradez científica, cuando pudo, en 1938, demostró como no podían existir, dentro del escenario de su relatividad, para de inmediato también darle fin al éter relativista.

In the last times some scholars tried to characterize Einstein’s distinction between ‘constructive’ – i.e. deductive - theories and ‘principle’ theories, the latter ones being preferred by Einstein. Here this distinction is qualified by an accurate inspection on past physical theories. Some previous theories are surely non-deductive theories. By a mutual comparison of them a set of features - mainly the arguing according to non-classical logic - are extracted. They manifest a new ideal model of organising a theory. (...) Einstein’s paper of 1905 on quanta, qualified by him as a ‘principle theory’, is interpreted according to this model of theory. Some unprecedented characteristic features are manifested. At the beginning of the same paper Einstein declared one more dichotomy about the kind of mathematics in theoretical physics. These two dichotomies are recognised as representing the foundations of theoretical physics. With respect to these dichotomies the choices by Einstein in the paper on quanta are the alternative choices to Newton’s ones. This fact gives reason to the ‘revolutionary’ nature that Einstein attributed to his paper. (shrink)

Für seine Würfelmetapher ergibt sich ein Spielraum von gegensätzlichen Sichtweisen.

Abstract Die moderne Physik besteht nicht nur aus neuen Entdeckungen und Erfindungen durch die Relativitätstheorie und durch die Quantenphysik. Sie besteht auch aus völlig neuen Sichtweisen und flexiblen Denkweisen von Zusammenhängen und Verschränkungen zwischen den Dingen. Die moderne Physik hat sich von dem Klischee des Schwarz-Weiß-Denkens verabschiedet, für das es nur getrennte Dinge, ohne fließende Übergänge gibt. Solche unbeweglichen, dogmatischen schwarzweißen Denkweisen können wir zurückverfolgen bis zu dem griechischen Philosophen Aristoteles. In der Zeit der Klassischen Mechanik hatten sie einen überwältigenden (...) Erfolg. Galilei behauptete, das Buch der Natur sei in der Sprache der Mathematik geschrieben. Das war die sehr kurzgefasste Formulierung der Klassischen Mechanik. Die moderne Physik hat sich keineswegs von der Mathematik verabschiedet, ganz und gar nicht. Doch der heilige Ernst und der starre und absolute Dogmatismus hat nachgelassen. Moderne Denkweisen in der Physik können mit den Begriffen von fließenden Übergängen, von Zwischenstufen, von Zusammenhängen zwischen den Dingen und von Schwingungen gekennzeichnet werden. Seit Faraday und Maxwell hat sich eine Verschiebung der Untersuchungsobjekte ergeben: Seit der Mitte des 19. Jahrhunderts, seit ca 1850, drehen sich die Denkmodelle der modernen Physik nicht mehr um getrennte, isolierten Körper, die im Nichts schwimmen, sondern um die Zwischenräume zwischen den Körpern und um die flexiblen Beziehungsgeflechte zwischen den Dingen und um die Netzwerke, die die Dinge umgeben. Das sind ganz neue physikalische Denkweisen, die durchaus Dunkelzonen und Zweifel und Ungewissheiten kennen, die den Bereich der Exaktheit überschatten. Neue Beiträge der physikalischen Denkweisen sind auch durch eine Flexibilität bei der Bildung von Begriffen gekennzeichnet. Sie lassen sich nicht auf einige wenige Begriffe oder auf eine starre und exakte Festlegung der Wortwahl festnageln. „Jede Philosophie bezieht ihre Farbe von der geheimen Lichtquelle eines Vorstellungshintergrunds, der niemals ausdrücklich in ihren Gedankenketten auftaucht“ (Whitehead) (1).

Am 14.

In 1935, Einstein, Podolsky and Rosen (EPR) originated the famous “EPR paradox” [1]. This argument concerns two spatially separated particles which have both perfectly correlated positions and momenta, as is predicted possible by quantum mechanics. The EPR paper spurred investigations into the nonlocality of quantum mechanics, leading to a direct challenge of the philosophies taken for granted by most physicists.The EPR conclusion was based on the assumption of local realism, and thus the EPR argument pinpoints a contradiction between local (...) realism and the completeness of quantum mechanics. Einstein’s 1927 gedanken experiment by using the probability representation of quantum states explained successfully. (shrink)

In this three-part paper, my concern is to expound and defend a conception of science, close to Einstein's, which I call aim-oriented empiricism. I argue that aim-oriented empiricsim has the following virtues. (i) It solve the problem of induction; (ii) it provides decisive reasons for rejecting van Fraassen's brilliantly defended but intuitively implausible constructive empiricism; (iii) it solves the problem of verisimilitude, the problem of explicating what it can mean to speak of scientific progress given that science advances from (...) one false theory to another; (iv) it enables us to hold that appropriate scientific theories, even though false, can nevertheless legitimately be interpreted realistically, as providing us with genuine , even if only approximate, knowledge of unobservable physical entities; (v) it provies science with a rational, even though fallible and non-mechanical, method for the discovery of fundamental new theories in physics. In the third part of the paper I show that Einstein made essential use of aim-oriented empiricism in scientific practice in developing special and general relativity. I conclude by considering to what extent Einstein came explicitly to advocate aim-oriented empiricism in his later years. (shrink)

In general relativity, a spacetime and a gravitational field form an indivisible unit: no field, no spacetime. This is a lesson of Einstein's hole argument. We use a simple transformation in a Schwartzschild pacetime to illustrate this.

To make out in what way Einstein’s manifold 1905 ‘annus mirabilis’ writings hang together one has to take into consideration Einstein’s strive for unity evinced in his persistent attempts to reconcile the basic research traditions of classical physics. Light quanta hypothesis and special theory of relativity turn out to be the contours of a more profound design, mere milestones of implementation of maxwellian electrodynamics, statistical mechanics and thermodynamics reconciliation programme. The conception of luminiferous ether was an insurmountable obstacle (...) for Einstein’s statistical thermodynamics in which the leading role was played by the light quanta paper. In his critical stand against the entrenched research traditions of classical physics Einstein was apparently influenced by David Hume and Ernst Mach. However, when related to creative momenta, Einstein’s 1905 unificationist modus operandi was drawn upon Mach’s principle of economy of thought taken in the context of his ‘instinctive knowledge’ doctrine and with promising inclinations of Kantian epistemology presuming the coincidence of both constructing theory and integrating intuition of Principle.

Max Jammer has recently proposed a model of God’s eternity based on the special theory of relativity, offering it as an example of how theologians should take into account what physicists say about the world. I start evaluating this proposal by a quick look at the classic Boethius-Aquinas model of divine eternity. The major objec-tion I advance against Jammer refers to Einstein’s subtle kind of realism. I offer var-ious reasons to show that Einstein’s realism was minimal. Moreover, even (...) this min-imal realism has been undermined by recent experimental work. If Jammer is sug-gesting that theologians should take Einstein’s physics seriously because it de-scribes the world, his argument is unconvincing because it doesn’t address the cru-cial question of Einstein’s realism, which makes all the difference.

Recent perspectival interpretations of Kant suggest a way of relating his epistemology to empirical science that makes it plausible to regard Einstein’stheory of relativity as having a Kantian grounding. This first of two articles exploring this topic focuses on how the foregoing hypothesis accounts for variousresonances between Kant’s philosophy and Einstein’s science. The great attention young Einstein paid to Kant in his early intellectual development demonstrates the plausibility of this hypothesis, while certain features of Einstein’s cultural-political (...) context account for his reluctance to acknowledge Kant’s influence, even though contemporary philosophers who regarded themselves as Kantians urged him to do so. The sequel argues that this Kantian grounding probably had a formative influence not only on Einstein’s discovery of the theory of relativity and his view of the nature of science, but also on his quasi-mystical, religious disposition.

While the philosophers of science discuss the General Relativity, the mathematical physicists do not question it. Therefore, there is a conflict. From the theoretical point view “the question of precisely what Einstein discovered remains unanswered, for we have no consensus over the exact nature of the theory 's foundations. Is this the theory that extends the relativity of motion from inertial motion to accelerated motion, as Einstein contended? Or is it just a theory that treats gravitation geometrically in (...) the spacetime setting?”. “The voices of dissent proclaim that Einstein was mistaken over the fundamental ideas of his own theory and that their basic principles are simply incompatible with this theory. Many newer texts make no mention of the principles Einstein listed as fundamental to his theory; they appear as neither axiom nor theorem. At best, they are recalled as ideas of purely historical importance in the theory's formation. The very name General Relativity is now routinely condemned as a misnomer and its use often zealously avoided in favour of, say , Einstein's theory of gravitation What has complicated an easy resolution of the debate are the alterations of Einstein's own position on the foundations of his theory”, (Norton, 1993). Of other hand from the mathematical point view the “General Relativity had been formulated as a messy set of partial differential equations in a single coordinate system. People were so pleased when they found a solution that they didn't care that it probably had no physical significance” (Hawking and Penrose, 1996). So, during a time, the declaration of quantum theorists:“I take the positivist viewpoint that a physical theory is just a mathematical model and that it is meaningless to ask whether it corresponds to reality. All that one can ask is that its predictions should be in agreement with observation.” (Hawking and Penrose, 1996)seemed to solve the problem, but recently achieved with the help of the tightly and collectively synchronized clocks in orbit frontally contradicts fundamental assumptions of the theory of Relativity. These observations are in disagree from predictions of the theory of Relativity. (Hatch, 2004a, 2004b, 2007). The mathematical model was developed first by Grossmann who presented it, in 1913, as the mathematical part of the Entwurf theory, still referred to a curved Minkowski spacetime. Einstein completed the mathematical model, in 1915, formulated for Riemann ́s spacetimes. In this paper, we present as of General Relativity currently remains only the mathematical model, darkened with the results of Hatch and, course, we conclude that a Einstein ́s gravity theory does not exist.

I briefly chart the position Einstein came to on nuclear weapons. Then I defend that position against Matchett's idea that Einstein behaved as a pop scientist and intervened ignorantly on an issue of wider concern.

The current technoscientific progress has led to a sectorization in the philosophy of science. Today the philosophy of science isn't is informal interested in studying old problems about the general characteristics of scientific practice. The interest of the philosopher of science is the study of concepts, problems and riddles of particular disciplines. Then, within this progress of philosophy of science, neuroscientific research stands out, because it invades issues traditionally addressed by the humanities, such as the nature of consciousness, action, knowledge, (...) normativity, etc. As a result, the new area of interdisciplinary study of neuroscience and philosophy arises: neurophilosophy. This emerging area applies neuroscientific concepts to traditional philosophical questions, limiting their responses to neuroscientific revelations about nervous systems. Neurophilosophy research focuses on problems related to the indirect nature of mind and brain, computational or representative analysis of brain process, relationships between psychological and neuroscientific research, adequate adaptations of physical and philosophical concepts in neuroscience and the place of cognitive functions. Now, the temporal representation of conscious experience and the types of the neural architecture to represent objects in time have aroused scientific interest. Under these interests, we focus on the studies on the temporary triadic structure of phenomenological consciousness in Dan Lloyd and Rick Grush. From Grush’s studies, the importance of Kantian ideas for cognitive neuroscience emerges, due to the active way in which Kant conceived space and time as forms of intuition, within which the mind interprets its experience. Under this perspective, the theoretical arguments of Dennett-Kinsbourne and Eagleman-Sejnowski represent winks in the direction of Kant-Husserl within the neuroscientific goal while considering that the contents provided by the mind included space, objects and perception of causal relationships. Then, theories of cognitive neuroscience are beginning to suggest that these elements are also, as Kant argued, interpretative elaborations provided by mind / brain, and not only content received from outside. In other words, current cognitive neuroscientific theories try to pass from its Humean phase to a Kantian phase. So, the challenge has been to explain that these elements are provided by the mind and the world itself, and how they have the content they have come from. These are lacking in current studies. Filling this gap helps to involve the analysis of the scientist’s experience in his theoretical attitude. In this sense, an investigation under the Kantian-Husserlian approach that involves pure intuitions a priori with the experience of the scientific and neuroscientific concepts represents a ground-breaking. At present, a neurophilosophical study about this does not exist. In this sense, one feasible proposal for research would be based on the application of neuroscientific results of Moser-Britt to philosophical problems of foundational notions in relativistic physics: space, time, space-time, field, etc., under the Kantian-Husserlian approach, which allows to demonstrate the multidisciplinary link between neurophilosophy and physics. This represents a ground-breaking area in current interests in scientific research, with a positive impact in the field of neuroscience, and contributing to the study of abstraction emphasizing the importance of Kant’s Copernican turn and Husserl’s phenomenological ideas in the construction of physical theories. -/- .

The paradox of 'the One and the Many' might, more generally, be understood as the paradox of relationship. In order for there to be relationship there must be at least two parties in relation. The relation must, at once, hold the parties apart (otherwise they would collapse into unity) while holding them together (otherwise relationship itself would cease). It must do so, further, without itself becoming a third party which would then, itself, need to be related. This paper considers this (...) paradox as we find it manifest in the theories of quantum physics, the Socratic pursuit of universals, and, finally, at the very heart of human personhood - where we discover it at the core of interpersonal relationships, existential anxiety, and social distress. It is suggested, in the end, that though reason cannot resolve the terms of this paradox, there is a potential solution to the existential problems that spring from it, a solution lying in what Jesus calls, simply, 'faith.'.

It is often thought the relativity of simultaneity is inconsistent with presentism. This would be troubling as it conflicts with common sense and—arguably—the empirical data. This note gives a novel fragmentalist-presentist theory that allows for the (non-trivial) relativity of simultaneity. A detailed account of the canonical moving train argument is considered. Alice, standing at the train station, forms her own ontological fragment, in which Bob’s frame of reference, given by the moving train, is modified by the Lorentz transformations. On the (...) other hand, Bob, in the train, forms his own ontological fragment from which Alice’s space and time are modified by the corresponding Lorentz transformations. Each fragment accommodates a unique present moment but does not contain information about the unique present moment of another fragment. This allows for a ‘universal’ present moment that extends throughout space, but only from the perspective of each fragment. The relativity of simultaneity is, as it were, ‘relativised’ to each fragment. This is related to the idea that, roughly speaking, the time of relativity is McTaggart’s (1908) B-series (earlier times to later times) and the time of quantum mechanics is a (fragmentalist) A-series (future/present/past), where these two related series characterize one dimension of time.

On the basis of historical and textual evidence, this paper claims that after his Tractatus, Wittgenstein was actually influenced by Einstein's theory of relativity and, the similarity of Einstein's relativity theory helps to illuminate some aspects of Wittgenstein's work. These claims find support in remarkable quotations where Wittgenstein speaks approvingly of Einstein's relativity theory and in the way these quotations are embedded in Wittgenstein's texts. The profound connection between Wittgenstein and relativity theory concerns not only Wittgenstein's “verificationist” (...) phase , but also Wittgenstein's later philosophy centred on the theme of rule‐following.

Einstein acknowledged that his reading of Hume influenced the development of his special theory of relativity. In this article, I juxtapose Hume’s philosophy with Einstein’s philosophical analysis related to his special relativity. I argue that there are two common points to be found in their writings, namely an empiricist theory of ideas and concepts, and a relationist ontology regarding space and time. The main thesis of this article is that these two points are intertwined in Hume and (...) class='Hi'>Einstein. (shrink)

I investigate the role of stability in cosmology through two episodes from the recent history of cosmology: Einstein’s static universe and Eddington’s demonstration of its instability, and the flatness problem of the hot big bang model and its claimed solution by inflationary theory. These episodes illustrate differing reactions to instability in cosmological models, both positive ones and negative ones. To provide some context to these reactions, I also situate them in relation to perspectives on stability from dynamical systems theory (...) and its epistemology. This reveals, for example, an insistence on stability as an extreme position in relation to the spectrum of physical systems which exhibit degrees of stability and fragility, one which has a pragmatic rationale, but not any deeper one.

Einstein déclare que les théories évoluent à travers des déclarations basées sur l'observation, sous la forme de lois empiriques, à partir desquelles des lois générales sont obtenues. L'intuition et la pensée déductive jouent un rôle important dans ce processus. Après la phase initiale, l'investigateur développe un système de pensée guidée par des données empiriques, construit logiquement à partir d'hypothèses fondamentales (axiomes). La « vérité » d'une théorie résulte de sa corrélation avec un grand nombre d'observations uniques. Pour les mêmes (...) données empiriques, plusieurs théories peuvent différer.

This essay explores Kaila's interpretation of the special theory of relativity. Although the relevance of his work to logical empiricism is well-known, not much has been written on what Kaila calls the ‘Einstein-Minkowski invariance theory’. Kaila's interpretation focuses on two salient features. First, he emphasizes the importance of the invariance of the spacetime interval. The general point about spacetime invariance has been known at least since Minkowski, yet Kaila applies his overall tripartite theory of invariances to space, time and (...) spacetime in an original way. Second, Kaila provides a non-conventionalist argument for the isotropic speed of electromagnetic signals. The standard Einstein synchrony is not a mere convention but a part of a larger empirical theory. According to Kaila's holistic principle of testability, which stands in contrast to the theses of translatability and verification, different items in the theory cannot be sharply divided into conventional and empirical. Kaila's invariantism/non-conventionalism about relativity reflects an interesting case in the gradual transition from positivism to realism within the philosophy of science. (shrink)

The Bohr Einstein debate on the meaning of quantum physics involved Einstein inventing a series of thought experiments to challenge the Copenhagen Interpretation of quantum physics. Einstein disliked many aspects of the Copenhagen Interpretation especially its idea of an observer dependent universe. Bohr was able to answer all Einstein’s objections to the Copenhagen Interpretation and so is usually considered as winning the debate. However the debate has continued into the present time as many scientists have been (...) unable to accept the idea of an observer dependent universe and many alternatives to the Copenhagen Interpretation have been proposed. However none of the alternatives has won general acceptance because all have problems that make them implausible or impossible. (shrink)

In this paper I shall argue in Section II that two of the standard arguments that have been put forth in support of Einstein’s Special Theory of Relativity do not support that theory and are quite compatible with what might be called an updated and perhaps even an enlightened Newtonian view of the Universe. This view will be presented in Section I. I shall call it the neo-Newtonian Theory, though I hasten to add there are a number of things (...) in it that Newton would not accept, though perhaps Galileo might have. Now there may be other arguments and/or pieces of empirical evidence which support the Special Theory of Relativity and cast doubt upon the neo-Newtonian view. Nevertheless, the two that I am going to examine are usually considered important. It might also be claimed that the two arguments that I am going to examine have only heuristic value. Perhaps this is so but they are usually put forward as supporting the Special Theory and refuting the neo-Newtonian Theory. Again I must stress that it is not my aim to cast any doubt on the Special Theory of Relativity nor on Einstein. His Special Theory and his General Theory stand at the zenith of human achievement. My only aim is to cast doubt on the assumption that the two arguments I examine support the Special Theory. (shrink)

Abstract Die moderne Physik besteht nicht nur aus neuen Entdeckungen und Erfindungen durch die Relativitätstheorie und durch die Quantenphysik. Sie besteht auch aus völlig neuen Sichtweisen und flexiblen Denkweisen von Zusammenhängen und Verschränkungen zwischen den Dingen. Die moderne Physik hat sich von dem Klischee des Schwarz-Weiß-Denkens verabschiedet, für das es nur getrennte Dinge, ohne fließende Übergänge gibt. Solche unbeweglichen, dogmatischen schwarzweißen Denkweisen können wir zurückverfolgen bis zu dem griechischen Philosophen Aristoteles. In der Zeit der Klassischen Mechanik hatten sie einen überwältigenden (...) Erfolg. Galilei behauptete, das Buch der Natur sei in der Sprache der Mathematik geschrieben. Das war die sehr kurzgefasste Formulierung der Klassischen Mechanik. Die moderne Physik hat sich keineswegs von der Mathematik verabschiedet, ganz und gar nicht. Doch der heilige Ernst und der starre und absolute Dogmatismus hat nachgelassen. Moderne Denkweisen in der Physik können mit den Begriffen von fließenden Übergängen, von Zwischenstufen, von Zusammenhängen zwischen den Dingen und von Schwingungen gekennzeichnet werden. Seit Faraday und Maxwell hat sich eine Verschiebung der Untersuchungsobjekte ergeben: Seit der Mitte des 19. Jahrhunderts, seit ca 1850, drehen sich die Denkmodelle der modernen Physik nicht mehr um getrennte, isolierten Körper, die im Nichts schwimmen, sondern um die Zwischenräume zwischen den Körpern und um die flexiblen Beziehungsgeflechte zwischen den Dingen und um die Netzwerke, die die Dinge umgeben. Das sind ganz neue physikalische Denkweisen, die durchaus Dunkelzonen und Zweifel und Ungewissheiten kennen, die den Bereich der Exaktheit überschatten. Neue Beiträge der physikalischen Denkweisen sind auch durch eine Flexibilität bei der Bildung von Begriffen gekennzeichnet. Sie lassen sich nicht auf einige wenige Begriffe oder auf eine starre und exakte Festlegung der Wortwahl festnageln. „Jede Philosophie bezieht ihre Farbe von der geheimen Lichtquelle eines Vorstellungshintergrunds, der niemals ausdrücklich in ihren Gedankenketten auftaucht“ (Whitehead) (1).

Time contraction is not a property of the moving body. Permanent contraction is against the constancy of the speed of light. Einstein uses wrong units of measurement and comes to wrong conclusions. We use the translation of the article "On the electrodynamics of moving bodies".

The arguments are exhibited in favour of the necessity to modify the history of the genesis and advancement of general relativity (GR). I demonstrate that the dynamic creation of GR had been continually governed by internal tensions between two research traditions, that of special relativity and Newton’s gravity. The encounter of the traditions and their interpenetration entailed construction of the hybrid domain at first with an irregular set of theoretical models. Step by step, on eliminating the contradictions between the models (...) contrived, the hybrid set was put into order. It is contended that the main reason of the GR victory over the rival programmes of Abraham and Nordström was a synthetic character of Einstein’s programme. Einstein had put forward as a basic synthetic principle the principle of equivalence that radically differed from that of rival approaches by its open, flexible and contra-ontological character.

From conceptual point of view, we argue about the nature of reality inferred from EPR argument in quantum mechanics.

Inspired by “One Note Samba,” a standard jazz repertoire, we present an outline of Bose-Einstein Condensate Cosmology (BECC). Although this approach seems awkward and a bit off the wall at first glance, it is not impossible to connect altogether BEC, Scalar Field Cosmology and Feshbach Resonance with Ermakov-Pinney equation. We also discuss shortly possible link with our previous paper, where we describe Newtonian Universe with Vortex in terms of Ermakov equation.

In this paper I discuss four versions of the basic idea of the French Enlightenment of the 18th century, namely: To learn from scientific progress how to achieve social progress towards an enlightened world. These four versions are: 1. The Traditional Enlightenment Programme. 2. The Popperian Version of the Enlightenment Programme. 3. The Improved Popperian Enlightenment Programme. 4. The New Enlightenment Programme. The Traditional Enlightenment Programme is the version of the idea upheld by the philosophes of the French Enlightenment. It (...) was developed throughout the 19th century and put into practice in the early 20th century with the creation of departments of social science in universities all over the world. It is however damagingly defective. The Popperian Version of the Enlightenment Programme is an improvement, but still defective. As we go down the list, from 1 and 2 to 3 and 4, each Programme improves on its predecessor, until with The New Enlightenment, which can in some respects be associated with Einstein, we arrive at a version of the idea which can genuinely help humanity make social progress towards an enlightened world.

Une géodésie spatio-temporelle pervertie résulte des notions de règles et d’horloges variables, qui sont prises pour avoir leur longueur et leur rythme affectés par le champ gravitationnel. D’autre part ce que nous pourrions appeler une géodésie concrète repose sur les notions de règles et d’horloges invariables de mesure d’unité. En fait, il s’agit d’une hypothèse de base de la relativité générale. Les règles et les horloges variables conduisent à une géodésie pervertie dans le sens où un espace-temps courbe pourrait être (...) vu comme provenant du départ de l’espace-temps Minkowskien comme un effet du champ gravitationnel sur le rythme d’horloges et la longueur des règles. Dans le cas d’une géodésie concrète, nous avons « directement » un espace-temps courbe dont la courbure peut être déterminée en utilisant des règles et des horloges de mesure d’unité (invariables). Dans cet article, nous défendrons la plausibilité que le point de vue d’Einstein sur la géométrie par rapport à la relativité générale est imprégné par une géodésie pervertie. (shrink)
