In modern physics, various fundamental problems have become topics of debate. There was the 20th century climb to a Standard Model, still accurate at the highest energy levels obtainable so far. But, since the 1970's, a different approach to physics advocates for theories such as string theory, known for their mathematical elegance, even though they either cannot be verified in data or contradict presently known experimental results. In philosophy of physics, there is a gradually emerging consensus that philosophy of physics (...) and physics somehow contribute to a common enterprise. But, there is little sign of progress toward consensus about the nature of that unity. All the while, it is generally recognized that physics is interdisciplinary. There are, of course, differences in focus. But, implicitly at least, there are no "sharp dividing lines" between physics and philosophy of physics; pure and applied physics; physical chemistry; biophysics; medical physics; history and philosophy of physics; physics and society; physics education; and so on. What, then, is progress in physics? The question here is not about ideal structures, but asks about what is going on in physics. Beginnings in discerning the presence of eight main tasks help reveal the (pre-) emergence of a normative omni-disciplinary basis for collaboration that, once adverted to, promises to be constitutive of a new and increasingly effective control of meaning. Originally discovered by Bernard Lonergan in 1965, progress in the new collaboration will not seek to eliminate specialized expertise. It will, though, divide tasks within an eightfold functional division of labor. This book invites attention to data for each of the eight main tasks evident and self-evident in existing scholarship in the community. (shrink)

Physical fitness is the foundation of all sports, good physical fitness not only enhances physical fitness and health, but also is very important for mastering volleyball skills and winning the game. Physical training is the core issue of training theory and practice method, and excellent physical quality will improve athletes' performance. Therefore, the purpose of this paper is to discuss the theoretical basis of volleyball specialized physical training and its application in actual training. First (...) of all, taking 14 female volleyball team members of Soochow University (national first-class athletes) as experimental subjects, we divided them into an experimental group and a control group by random number method for 12-week physical training. The physical quality of the athletes before and after the experiment was measured by the physical quality test index adopted by the national female volleyball training camp. The results show that 1) both conventional physical training and improved comprehensive physical training can enhance the physical quality of female volleyball players, but the improved comprehensive physical training is better; 2) Compared with routine physical training, the 12-week comprehensive physical training method has more advantages in improving the lower extremity strength quality and lower extremity movement speed of female volleyball athletes.Consequently,the improved comprehensive physical training based on conventional physical training and combining theory and practice can further optimize the training mode, which has a very positive effect on improving the special physical quality of female volleyball athletes.

In recent decades, the development of sciences and technologies had a significant impact in society. This impact has been object of analysis from several standpoints, i.e., scientific, communication, historical and anthropological. Consequently, serious changes were required by the society. One of these has been the emerging relationship science in society and its foundations of applied sciences. A related foundational challenging is the educational process, which was and still is an unlimited challenge for teachers and professors: i.e., levels of understanding, curricula, (...) activing critical engagement, transfer knowledge—and—skills, management, classroom and subsequently pre-service teachers need special teacher education. Taking into account Joule’s bicentenary commemoration in physics and Nature of Science teaching this paper introduces to a level of inquiring within historical and NoS approaches in the pre-service teachers, typically science, technology, engineering and mathematics. In particular, history and historiography of Joule’s physics are dealt with. (shrink)

Physical Relativity explores the nature of the distinction at the heart of Einstein's 1905 formulation of his special theory of relativity: that between kinematics and dynamics. Einstein himself became increasingly uncomfortable with this distinction, and with the limitations of what he called the 'principle theory' approach inspired by the logic of thermodynamics. A handful of physicists and philosophers have over the last century likewise expressed doubts about Einstein's treatment of the relativistic behaviour of rigid bodies and clocks in motion (...) in the kinematical part of his great paper, and suggested that the dynamical understanding of length contraction and time dilation intimated by the immediate precursors of Einstein is more fundamental. Harvey Brown both examines and extends these arguments (which support a more 'constructive' approach to relativistic effects in Einstein's terminology), after giving a careful analysis of key features of the pre-history of relativity theory. He argues furthermore that the geometrization of the theory by Minkowski in 1908 brought illumination, but not a causal explanation of relativistic effects. Finally, Brown tries to show that the dynamical interpretation of special relativity defended in the book is consistent with the role this theory must play as a limiting case of Einstein's 1915 theory of gravity: the general theory of relativity.Appearing in the centennial year of Einstein's celebrated paper on special relativity, Physical Relativity is an unusual, critical examination of the way Einstein formulated his theory. It also examines in detail certain specific historical and conceptual issues that have long given rise to debate in both special and general relativity theory, such as the conventionality of simultaneity, the principle of general covariance, and the consistency or otherwise of the special theory with quantum mechanics. Harvey Brown' s new interpretation of relativity theory will interest anyone working on these central topics in modern physics. (shrink)

In his Physicae synopsis of 1633, Johann Amos Comenius (1592–1670) presented a list of previous representatives of Mosaic physics. They included Francisco Vallés (1524–1592), Lambert Daneau (1530–1595), Levinus Lemnius (1505–1568), Thomas Lydiat (1572–1646), Kort Aslakssøn (1564–1624), and Otto Casmann (1562–1607). Although Ann Blair has noted some time ago that Mosaic physics did not form a unified school but was, rather, a cluster of names linked by an agenda and mutual references, the question remains as to what exact topics the individual (...) representatives were pursuing and, above all, whether it is possible to find thematic overlaps and referential bonds between all six authors named by Comenius. This paper, therefore, analyzes their definition and understanding of the Mosaic program with particular attention to the imperative to read the Scriptures literally and explores in detail the mutual links of Comenius’s alleged forerunners.

Statistical mechanics is one of the crucial fundamental theories of physics, and in his new book Lawrence Sklar, one of the pre-eminent philosophers of physics, offers a comprehensive, non-technical introduction to that theory and to attempts to understand its foundational elements. Among the topics treated in detail are: probability and statistical explanation, the basic issues in both equilibrium and non-equilibrium statistical mechanics, the role of cosmology, the reduction of thermodynamics to statistical mechanics, and the alleged foundation of the very notion (...) of time asymmetry in the entropic asymmetry of systems in time. The book emphasises the interaction of scientific and philosophical modes of reasoning, and in this way will interest all philosophers of science as well as those in physics and chemistry concerned with philosophical questions. The book could also be read by an informed general reader interested in the foundations of modern science. (shrink)

Covid-19 lockdown restrictions constitute a population-wide “life-change event” disrupting normal daily routines. It was proposed that as a result of these lockdown restrictions, physical activity levels would likely decline. However, it could also be argued that lifestyle disruption may result in the formation of increased physical activity habits. Using a longitudinal design, the purpose of this study was to investigate changes in physical activity of different intensities, across individuals who differed in activity levels prior to lockdown restrictions (...) being imposed, and across three time periods: pre-, during- and post-lockdown. This study also examined the extent to which the experience of daily hassles explained any changes in physical activity. A convenience sample recruited through social media, provided data from an online survey administered during weeks 2–3 of a 5-week lockdown and 231 participants provided complete data again 6 weeks post-lockdown. Participants completed the International Physical Activity Questionnaire–Short Form and the Daily Hassles Scale. Results showed that vigorous and moderate intensity PA were significantly lower during- and post-lockdown compared to pre-lockdown in those individuals who had been highly active pre-lockdown. In contrast, for moderately active individuals pre-lockdown, vigorous and moderate intensity PA was significantly higher during-lockdown compared to pre-lockdown, and these increased levels of vigorous PA were maintained post-lockdown. Participants experienced daily hassles due to inner concerns, time pressures, family, and financial concerns to the same extent during- and post-lockdown. Those daily hassles had a small negative predictive effect on post-lockdown PA. It appears that to understand the effect of COVID-19 restrictions on PA, the activity status of individuals pre-lockdown needs to be taken into account. The daily hassles appeared to play a role in post-lockdown PA behavior, but future research should investigate why these results occurred. (shrink)

For more than a century the notion of a pre-established harmony between the mathematical and physical sciences has played an important role not only in the rhetoric of mathematicians and theoretical physicists, but also as a doctrine guiding much of their research. Strongly mathematized branches of physics, such as the vortex theory of atoms popular in Victorian Britain, were not unknown in the nineteenth century, but it was only in the environment of fin-de-siècle Germany that the idea of a (...) pre-established harmony really took off and became part of the mathematicians’ ideology. Important historical figures were in this respect David Hilbert, Hermann Minkowski and, somewhat later, Albert Einstein. Roughly similar ideas can be found also among British theorists, among whom Arthur Eddington, Arthur Milne, and Paul Dirac are singled out. Although largely limited to the period 1870–1940, the paper also considers Max Tegmark’s recent hypothesis of the universe being a one-to-one reflection of mathematical structures. (shrink)

Stoic physics, based entirely on the continuum concept, is one of the great original contributions in the history of physical systems. Building on The Physical World of the Greeks, the author describes the main aspects of the Stoic continuum theory, traces its origins back to pre-Stoic science and philosophy, and shows the attempts of the Stoics to work out a coherent system of thought that would explain the essential phenomena of the physical world by a few basic (...) assumptions.

This paper provides a critical expansion of the foundational field framework proposed by Maria Strømme (2025). By introducing the Universal Field of Intelligence (UFI), the author bridges quantum physics and non-dual philosophy, offering a non-reductionist model for the emergence of structure and experience. Key contributions include the formulation of the $n^2$ Coherence Model and the definition of the Biological Antenna within the pre-spatiotemporal order.

In this paper, I analyse Émilie Du Châtelet’s (1706–49) account of causation which, in turn, is crucial for understanding her philosophical main work, the Institutions de physique (1740/1742). So far, the topic of causation in Du Châtelet’s thought has received but little attention despite its importance. I will show that Du Châtelet’s account of physical causation is that of physical influx much in line with the position taken by some of the most prominent eighteenth-century German metaphysicians at the (...) time of the publication of her Institutions: Martin Knutzen (1713–49), Johann Peter Reusch (1691–1758) and the pre-Critical Immanuel Kant (1724–1804). I will argue that physical influx takes place at the level of simple substances or physical monads, and I will defend my interpretation against the main objection to physical influx: that it conflicts with Leibniz’s non-transfer argument. The ultimate metaphysical details regarding how physical influx has to be understood remain an issue, that of understanding the causality of the cause. This, however, is an issue that other causal theories face, too (in their own way). (shrink)

Poincaré is a pre-eminent figure: as one of the greatest of mathematicians; as a contributor of prime importance to the development of physical theory at a time when physics was undergoing a profound transformation; and as a philosopher. However, I think that Poincaré, with all this virtue, made a serious philosophical mistake. In Poincaré’s own work, this error seems to me to have kept him from several fundamental discoveries in physics. The hypothesis that Poincaré would have made these discoveries (...) if he had not been misled by a philosophical error is not one that lends itself to conclusive assessment; but what I wish to do is to lay out the main circumstances of the case so as to make clear, at least, that the issue of philosophic principle involved, and the questions of fundamental physics under discussion, are of considerable mutual relevance.

Much recent discussion has focused on the nature of artifacts, particularly on whether they have essences. While it is often held that artifacts are intention-dependent and necessarily have functions, it is equally commonly held, though far less discussed, that artifacts are the result of physical modification of some material objects. This paper argues that the physical modification condition on artifacts is false. First, it formulates the physical modification condition perspicuously for the first time. Second, it offers counterexamples (...) to this condition, both concrete and abstract. Third, it considers, and rejects, two responses to these counterexamples, one which appeals to the distinction between being a K and being used as a K and another which argues that the counterexamples are merely of functional, not artifactual, kinds. Finally, it considers, and rejects, a more general objection that appropriation makes artifact creation too easy. As a consequence, artifacts can be created by appropriating pre-existing objects and it sketches some success conditions for such appropriation. (shrink)

The language of physics is mathematics, and physics ideas, laws and models describing phenomena are usually represented in mathematical form. Therefore, an understanding of how to navigate between phenomena and the models representing them in mathematical form is important for a physics teacher so that the teacher can make physics understandable to students. Here, the focus is on the “experimental mathematization,” how laws are established through quantifying experiments. A sequence from qualitative experiments to mathematical formulations through quantifying experiments on electric (...) current, voltage and resistance in pre-service physics teachers’ laboratory reports is examined. The way students reason and justify the mathematical formulation of the measurement results and how they combine the treatment and presentation of empirical data to their justifications is analyzed. The results show that pre-service physics teachers understand the basic idea of how quantifying experiments establish the quantities and laws but are not able to argue it in a justified manner.

More than a century ago, Russell launched a forceful attack on causation, arguing not only that modern physics has no need for causal notions but also that our belief in causation is a relic of a pre-scientific view of the world. He thereby initiated a debate about the relations between physics and causation that remains very much alive today. While virtually everybody nowadays rejects Russell's causal eliminativism, many philosophers have been convinced by Russell that the fundamental physical structure of (...) our world doesn't contain causal relations. This raises the question of how to reconcile the central role of causal concepts in the special sciences and in common sense with the putative absence of causation in fundamental physics. (shrink)

Physics in Oxford, 1839-1939 offers a challenging new interpretation of pre-war physics at the University of Oxford, which was far more dynamic than most historians and physicists have been prepared to believe. It explains, on the one hand, how attempts to develop the University's Clarendon Laboratory by Robert Clifton, Professor of Experimental Philosophy from 1865 to 1915, were thwarted by academic politics and funding problems, and latterly by Clifton's idiosyncratic concern with precision instrumentation. Conversely, by examining in detail the work (...) of college fellows and their laboratories, the book reconstructs the decentralized environment that allowed physics to enter on a period of conspicuous vigour in the late nineteenth and early twentieth centuries, especially at the characteristically Oxonian intersections between physics, physical chemistry, mechanics, and mathematics. Whereas histories of Cambridge physics have tended to focus on the self-sustaining culture of the Cavendish Laboratory, it was Oxford's college-trained physicists who enabled the discipline to flourish in due course in university as well as college facilities, notably under the newly appointed professors, J. S. E. Townsend from 1900 and F. A. Lindemann from 1919. This broader perspective allows us to understand better the vitality with which physicists in Oxford responded to the demands of wartime research on radar and techniques relevant to atomic weapons and laid the foundations for the dramatic post-war expansion in teaching and research that has endowed Oxford with one of the largest and most dynamic schools of physics in the world.

The rich blend of theories and experiences that made the history of physics possible still now enlightens the scientific method. We stress the need to learn from this method the force of making its principles explicit, while developing a rich diversity of theories, which are often incompatible. Unity is preserved by common founding principles and their mathematical form, such as the understanding of conservation properties (energy, momentum etc.) in terms of symmetries. When moving from the inert to the living state (...) of matter, new challenges are posed, beginning with biological “heterogenesis”, as “genesis of and from diversity” in a changing space of pertinent observables and parameters: the Darwinian ecosystem. The question that is posed is how we may consistently embed the theories of the inert into biology. By naturalization we mean an analysis of physics as part of the sciences of nature, not as the science governing them all. In particular, the founding symmetry principles of physical theories, often used to “naturalize” (but, actually, to “physicalize”) other sciences, will instead be framed in more general dynamics which deal with fundamental changes of symmetries, as they apply, in our views, in all historical sciences, beginning with biology. This paper will accordingly explore the notion of (non-)conservative extension of theories in a precise mathematical sense. We stress a perspectival epistemology that promotes a dialogue of theories, in search for bridges or even unity, inspired by the method of “unification” at the core of major theoretical inventions in physics. Our main motivation is the need to go beyond the strong dualistic separation of space (or of the more general “phase space”) as a pre-given container of the dynamics of matter, that biased physics from Aristotle to Newton and, in a technically different way, even Einstein.

An influential tradition in the philosophy of causation has it that all token causal facts are, or are reducible to, facts about difference-making. Challenges to this tradition have typically focused on pre-emption cases, in which a cause apparently fails to make a difference to its effect. However, a novel challenge to the difference-making approach has recently been issued by Alyssa Ney. Ney defends causal foundationalism, which she characterizes as the thesis that facts about difference-making depend upon facts about physical (...) causation. She takes this to imply that causation is not fundamentally a matter of difference-making. In this paper, I defend the difference-making approach against Ney’s argument. I also offer some positive reasons for thinking, pace Ney, that causation is fundamentally a matter of difference-making. (shrink)

The present work is focussed on the completeness of physics, or what is here called the Completeness Thesis: the claim that the domain of the physical is causally closed. Two major questions are tackled: How best is the Completeness Thesis to be formulated? What can be said in defence of the Completeness Thesis? My principal conclusions are that the Completeness Thesis can be coherently formulated, and that the evidence in favour if it significantly outweighs that against it. In opposition (...) to those who argue that formulation is impossible because no account of what is to count as physical can be provided, I argue that as long as the purpose of the argument in which the account is to be used are borne in mind there are no significant difficulties. The account of the physical which I develop holds as physical whatever is needed to fix the likelihood of pre-theoretically given physical effects, and hypothesises in addition that no chemical, biological or psychological factors will be needed in this way. The thus formulated Completeness Thesis is coherent, and has significant empirical content. In opposition to those who defend the doctrine of emergentism by means of philosophical arguments I contend that those arguments are flawed, setting up misleading dichotomies between needlessly attenuated alternatives and assuming the truth of what is to be proved. Against those who defend emergentism by appeal to the evidence, I argue that the history of science since the nineteenth century shows clearly that the empirical credentials of the view that the world is causally closed at the level of a small number of purely physical forces and types of energy is stronger than ever, and the credentials of emergentism correspondingly weaker. In opposition to those who argue that difficulties with reductionism point to the implausibility of the Completeness Thesis I argue that completeness in no way entails the kinds of reductionism which give rise to the difficulties in question. I argue further that the truth of the Completeness Thesis is in fact compatible with a great deal of taxonomic disorder and the impossibility of any general reduction of non-fundamental descriptions to fundamental ones. In opposition to those who argue that the epistemological credentials of fundamental physical laws are poor, and that those laws should in fact be seen as false, I contend that truth preserving accounts of fundamental laws can be developed. Developing such an account, I test it by considering cases of the composition of forces and causes, where what takes place is different to what is predicted by reference to any single law, and argue that viewing laws as tendencies allows their truth to be preserved, and sense to be made of both the experimental discovery of laws, and the fact that composition enables accurate prediction in at least some cases.

Since antiquity, there had been close ties between imagined movement through built spaces and organising knowledge. Philosophers and rhetorical theorists had argued that one remembered most effectively by imagining a sequence of places, including built spaces, and storing images of what should be recalled in those places. Authors of medieval pilgrimage narratives had led their readers on tours of sacred sites beginning in the twelfth century. From the late fifteenth century, however, imagined movement became more insistently physical and increasingly (...) deployed to communicate, rather than simply store, knowledge: built memory spaces were for the first time categorised according to size; volumes began to present pre-designed memory structures devoted to a particular topic; guidebooks to Rome started to lead readers on tours similar to those of pilgrimage narratives; and university botanic gardens offered the lived equivalent of sequences of memory places. By the seventeenth century, tours with sequences of spaces that stored information were a familiar technique across discourses from natural philosophy to architecture. This article examines the increasing physicality of imagined movement through these spaces and its connection to communicating knowledge as well as to shaping the attitudes of readers. I focus on mnemonic treatises and volumes presenting pre-designed spaces, the books where imagined movement was especially apparent, alongside guidebooks and botanic gardens. Consequently, built memory spaces, which have been little studied, are highlighted, and two rich but usually discrete strands of early modern history are brought together: history of memory and studies of movement through the built environment.

Education is so strongly emphasized in the Chinese culture that academic success is widely regarded as the only indicator of success, while too much physical activity is often discouraged because it drains energy and affects academic concentration. This study investigated the relations among academic achievement, self?esteem, school conduct and physical activity level. The participants were 333 Chinese pre?adolescents (aged 8?12) in Hong Kong. Examination results and conduct grades were obtained from the school records. Global self?esteem was measured with (...) the Physical self?description questionnaire (PSDQ), while physical activity patterns of the children were assessed with the Physical activity questionnaire for children (PAQ?C). Results showed that high academic achievers consistently attained better school conduct marks. However, physical activity level was quite an independent entity that was related neither to academic achievement nor school conduct. Furthermore, regression analyses showed that only academically high?achieving boys and physically active boys had higher self?esteem. (shrink)

If there is one question which stands forth pre-eminently from among the many problems with which physical science bristles, it is that of the ontological status of the world which physics is exploring. What is reality in the eyes of science, and what are we to understand the physicist to mean when he refers to the “real world”? Can we agree with him when he assures us that physical science represents a progress towards pure truth? There seems to (...) be a certain reluctance on the part of twentieth-century physicists to face the ontological question which I think their colleagues of the nineteenth century did not share to the same extent.

In various philosophical, religious and mystical traditions, beauty is often related to intellectual upliftment and spiritual ascent, which suggests that besides its common aesthetic value it may also acquire an epistemic, metaphysical and spiritual meaning or value. I will examine in detail three accounts in which beauty, at times inseparable from desire and love, mediates between physical, intellectual and spiritual levels of existence. Since beauty, in all three accounts, takes on a mediatory role or function,1 I will name these (...) mediations as follows: ancient Greek Eros-mediation or Beauty-mediation (Plato: ca. 429-347 BCE), late medieval Italian Beauty and Love-mediation (Dante Alighieri: 1265-1321) and pre-modern Indian Beauty and Love-mediation (Rūpa Gosvāmi: 1470/90-1564 CE).2 In the first section, I will analyse the stages of Eros or Beauty mediation in Plato; in the second section, I will turn to Dante’s Beauty and Love-mediation and compare it with Plato’s account. In the third section, I will analyse Rūpa’s account of Beauty and Love-mediation in comparison with both Plato and Dante. I will argue that there are certain patterns of mediation mutually shared if not between all three accounts, then at least between two of them. While Plato’s account clearly influenced Dante and was well integrated into Dante’s account, there is no mention or evidence of a pre-modern Bengali theologian influenced by ancient Greek and medieval Italian philosophy and mysticism. However, a strong convergence of elements of Beauty-mediations in Plato and Dante, as well as Beauty and Love-mediations in Dante and Rūpa Gosvāmi, confirms the universality of certain features of Beauty and Love-mediation and speaks in support of an all-inclusive account of them.3 -/- 1 By Beauty-mediation I mean an aesthetic, intellectual or spiritual reconciliation between opposites, such as human and divine, mortal and immortal, particular and universal, sexual and sacred and so on. 2 Rūpa Gosvāmi was an Indian theologian. More information about him is provided in section 3. 3 I am here applying transitivity: if Plato’s account (A) shares elements with Dante’s account (B) and if Dante’s account (B) shares those same elements with Rūpa’s account (C), then Plato’s (A) and Rūpa’s (C) accounts share some elements as well. Obviously, all accounts have some different elements not mutually shared, but I will not deal with them here. (shrink)

In this article, I examine the inversion of essential cultural values, such as physical perfection and the sports spirit, in 20th-century Europe. Periods emerged when physical perfection, once celebrated, morphed into tools for eugenics, racial theories, and ideological segregation. Similarly, the sports spirit became entangled in political and ideological conflicts. I approach this through the Marxist lens of ‘base—superstructure’ relations, focusing on the biological ‘base’, often misinterpreted through social Darwinism. This base is not subject to dialectical changes, does (...) not develop spirally but remains a constant fundament of human existence. It anchors pre-human and human interactions centered on physical fitness and interpersonal competition rooted in sexual selection. From this premise, I propose a philosophical model progressing from the general to the specific, built on four levels. At its foundation lies the unchanging physicality-agonistic ‘base’. From this base emerge three enduring cultural ‘structures’: physical culture, agonistic culture, and the uniting of these two sports cultures. These structures produce two cardinal values—physical perfection and sports spirit—while also giving rise to inversive superstructures that veer toward cultural distortions. I connect these inversions to the influence of elite groups shaping public opinion, aligning this analysis with Antonio Gramsci’s theory of hegemony. In this last stage, this perspective finds synergy with traditional Marxism, highlighting the role of elites in steering societal values and cultural frameworks. (shrink)

I argue that in modern algebraic-formulated science the ‘physical constant’ can be understood, for practical purposes, as an ‘identifier’ of a universal law of nature. This identifying role is possible because the concept of ‘physical constant’ fulfills the same need for universality, stability, and fundamentality (as universal laws) for increasing the epistemic value of a scientific theory. This can be demonstrated in two different ways. The first involves a thought experiment envisioning science without physical constants, which appears (...) to be a science of local and particular laws. The second is the observation that physical constants mostly emerge as components in an algebraic formulation of universal laws, but not in the algebraic formulation of particular laws. This observation about the link between physical constants and universal laws of nature, if correct, makes two contributions. First, it clarifies, at least partially, the ambiguity in the use (and the absence) of the concept ‘law’ in contemporary science. Second, it can help in distinguishing between a universal law and a particular law, while avoiding one of the abiding philosophical problems regarding laws of nature—the problem of the ceteris-paribus criterion for a generalization.

Many people believe in the power of positive thinking (i.e., how thoughts and attitude can shape their future) yet, despite a plethora of books on this subject, no previous author has credibly explained how mere thoughts are able to tangibly influence future events. To explain the connection, Dr. Donlan presents a new paradigm of nature coupled with a viable explanation of how our right cerebral hemisphere has evolved circuitry that can tap into the hidden domain of the metaphysical. To support (...) this premise, he exposes the reader to the worlds of physics, metaphysics, brain architecture, and evolution. Donlan then introduces the many problems associated with the current model and contrasts it with a new view which remedies many of the issues facing theoretical physicists today. Important to its central theme, the book's proposed paradigm supports the remarkable notion that the future can only be created with thoughts. In the final analysis, the author brings his readers through the necessary steps to put this knowledge to work to help them (pre)ordain their own realities. (shrink)

When the term “physicalism” is not used interchangeably with “materialism” it typically names a meta-linguistic or methodological view that is intended to sidestep metaphysical debates like those between materialists, dualists, and idealists. Well-known versions of this anti-metaphysical outlook were defended in the 1930s by Otto Neurath and Rudolf Carnap. Indeed, according to a standard account, these thinkers introduced the word “physicalism” into philosophy. In this paper, I explore the pre-history of physicalism as an anti-metaphysical articulation of the unity of science. (...) The terms “physicalism” and “physicalists” were first used in the 1850s, far earlier than is commonly recognized, to refer to a cluster of views developed by phrenologists and early positivists such as Franz Joseph Gall and Henri de Saint-Simon. I argue that this fact has more than mere etymological significance. These nineteenth-century thinkers expressed a distinctive proto-physicalist position that contained two core components of the Vienna Circle’s physicalism—the unity of method and unity of laws. They also contributed to a tradition that influenced the Vienna Circle’s agenda of using the unified conceptual structure of the sciences, which results from physicalism, to enable social progress.

Surfaces have been much studied, but no consensus has been reached about the actual physical nature of the surface of a three-dimensional, mind-independent physical object. I analyze, from a common sense or “folk” perspective, the surface of a physically-extended simple in a space containing no other objects. From this, I propose the novel idea that a surface is not a part of an object or its outside but instead is made of two components: 1) the object as a (...) unit whole, or a unity, which acts as a barrier to 2) the outside space next to the object. I further propose that if there is no pre-existing outside space, the process of grouping zero or more things together into a new unit whole and physical object creates one with the grouping/unit-wholeness acting as a barrier to that newly created outside. A second test case containing 3 components and an observer is used to defend the hypothesis that a new outside space is created by the grouping process. When combined with a previously published example of an extended simple containing nothing inside, the two-part surface hypothesis suggests a process by which this simple can undergo self-replication leading to a Big Bang-like expansion of space. This offers a possible solution to an important question in philosophy: How do you start with one or a few fundamental existent entities and end up with the many contingent entities we see in the universe around us?

Physical fatigue negatively affects postural control, resulting in impaired balance performance in young and older adults. Similar effects on postural control can be observed for mental fatigue mainly in older adults. Controversial results exist for young adults. There is a void in the literature on the effects of fatigue on balance and cortical activity. Therefore, this study aimed to examine the acute effects of PF and MF on postural sway and cortical activity. Fifteen healthy young adults aged 28 ± (...) 3 years participated in this study. MF and PF protocols comprising of an all-out repeated sit-to-stand task and a computer-based attention network test, respectively, were applied in random order. Pre and post fatigue, cortical activity and postural sway were tested during a challenging bipedal balance board task. Absolute spectral power was calculated for theta, alpha-2, beta-1, and beta-2 in frontal, central, and parietal regions of interest and baseline-normalized. Inference statistics revealed a significant time-by-fatigue interaction for CoPd and CoPv, and a significant main effect of time for CoP variability. Post hoc analyses showed a significant increase in CoPd and CoPv following PF but not MF. For cortical activity, a significant time-by-fatigue interaction was found for relative alpha-2 power in parietal areas. Post hoc tests indicated larger alpha-2 power increases after PF compared to MF. In addition, changes in parietal alpha-2 power and measures of postural sway did not correlate significantly, irrespective of the applied fatigue protocol. No significant changes were found for the other frequency bands, irrespective of the fatigue protocol and ROI under investigation. Thus, the applied PF protocol resulted in increased postural sway and CoP variability accompanied by enhanced alpha-2 power in the parietal ROI while MF led to increased CoP variability and alpha-2 power in our sample of young adults. Potential underlying cortical mechanisms responsible for the greater increase in parietal alpha-2 power after PF were discussed but could not be clearly identified as cause. Therefore, further future research is needed to decipher alternative interpretations. (shrink)

Throughout the world, female students are less likely than males to take advanced physics courses. This mixed-methods study uses a concurrent, nested design to study an online homework intervention designed to address choice and achievement. A choice of three different contexts (biological, sports, and traditional) were offered to students for each physics problem, intending to stimulate females’ interest and enhance achievement. Informed by aspects of Artino’s social-cognitive model of academic motivation and emotion, we investigated: Which context of physics problems do (...) males and females select?; What explanations do students give for their choices?; Are there differences in the achievement of males and females?; and Is there a relationship between student achievement and the context selected? Fifty-two high school physics students from five U.S. states participated. Data included pre and post Force Concept Inventory scores, homework context choices and achievement, and rationales for choices. Findings indicate that females were most likely to select biology contexts; males, traditional. All students made more attempts on video questions over word questions, although females did not score as well. For all questions, students generally persisted until they answered them correctly, with females taking fewer attempts on problems. Context choice was mostly driven by interest, for males, and perceptions of difficulty level for females; however, rationales were indistinguishable by gender. On their first homework question attempt, females scored significantly better than the males. Initially, males had significantly higher FCI scores; post homework intervention, females increased their mean scores significantly on the FCI, erasing the initial gender gap, with no growth nor decline in males’ scores. Females with FCI growth were equally as likely to choose biology contexts as traditional contexts; males were more likely to choose biology contexts. Findings from this study suggest that modest changes to homework problems that provide choice and make the physics problems more contextually interesting - even without changes in classroom instruction - could increase interest and motivation students and increase achievement for both male and female students. Recommendations will be discussed. (shrink)

Before the story can be told, however, some stage-setting is necessary. First, it is important to be clear about the most basic doctrines of Pre-established Harmony, Occasionalism, and Physical Influx. Physical Influx asserts intersubstantial causation amongst finite substances. For instance, when I appear to kick a ball, I really am the cause of the ball's motion. Pre-established Harmony denies intersubstantial causation, but affirms intrasubstantial causation. According to Pre-established Harmony, then, I am not the cause of the ball's motion, (...) but rather the ball is simply causing itself to move. Occasionalism, like Pre-established Harmony, denies intersubstantial causation, but, unlike Pre-established Harmony, it denies intrasubstantial causation as well. Occasionalism typically asserts that God alone, that is, an infinite substance, is the cause of all changes, and thus of the ball's motion. Though there are other ways of defining these causal theories, this way has the advantage that the causal theories form an exhaustive disjunction. (shrink)

I review the role of probability in contemporary physics and the origin of probabilistic time asymmetry, beginning with the pre-quantum case but concentrating on quantum theory. I argue that quantum mechanics radically changes the pre-quantum situation and that the philosophical nature of objective probability in physics, and of probabilistic asymmetry in time, is dependent on the correct resolution of the quantum measurement problem.

The Lorentz transformations may be derived based on the Principle of Relativity and a few other plausible physical assumptions, without introducing the Principle of the Constancy of the Velocity of Light. All existing derivations of this kind introduce a (pre-) causality (or equivalent) condition in order to constrain the transformations of coordinates to assume the form of the Lorentz transformations (or their Galilean limit). We show how such a condition may be dropped: as a consequence, the Principle of Relativity (...) in itself implies any causal relationship to be conserved under a change of reference frame. (shrink)

Emilie Du Châtelet’s Institutions de physique (1740) predates Kant’s pre-Critical texts, in which he develops his account of physical influx. This chapter draws on Kant’s pre-Critical account to shed light on how Du Châtelet might have responded to a central objection against physical influx raised by Leibniz. I first show that despite Du Châtelet’s explicit claim in the preface of the Institutions to be expounding Leibniz’s metaphysics, her metaphysical commitments diverge from Leibniz's in a striking way: unlike Leibniz, (...) she seems to endorse physical influx for created substances, the view that created substances stand in transeunt causal relations to one another. I then reconstruct Leibniz’s objection that transeunt causation between substances is metaphysically incoherent because it involves the transfer of accidents. Finally, I argue that Du Châtelet, on the basis of her Institutions, has the resources to address this objection. The key insight, which Du Châtelet shares with the pre-Critical Kant, is that transeunt substantial causation requires the causal powers of both the substance that acts and the substance that is acted upon.

Time appears to flow. Our experience of change and our own being in time reveals a relentless motion or passage. This apparent time motion is a profound enigma for currently well-known conceptions of time. I argue that they can neither explain it nor explain it away. This book describes a new theory of time that renders temporal passage fully intelligible. It treats time motion seriously by building in motion as a metaphysically fundamental feature of the physical universe, whose principle (...) form is through higher-dimensional space. This motion-first metaphysics then rejects the orthodox view that motion is explained in terms of space and time, but rather uses space and motion to define time. This approach requires rethinking the physicist’s 4D manifold M. The orthodox view is that M is space-time: a vast concrete 4D block locating all things whose 4th-dimension is time. According to the motion-first metaphysics I develop, M is not space-time but instead a pre-physical aspect of a fundamentally dynamic reality. Time is not M’s 4th dimension. Instead time is the ineluctable motion through the 4th-dimension that all persisting things undergo. I argue that my motion-first metaphysics solves puzzles of time, change, and persistence. It’s also consistent with special relativity—time dilation, length contraction, and relativity of simultaneity—although it’s not consistent with the Minkowskian interpretation of M as spacetime.

Physical activity, and likely the motivation for it, varies throughout the day. The aim of this investigation was to create a short assessment (CRAVE: Cravings for Rest and Volitional Energy Expenditure) to measure motivation states (wants, desires, urges) for physical activity and sedentary behaviors. Five studies were conducted to develop and evaluate the construct validity and reliability of the scale, with 1,035 participants completing the scale a total of 1,697 times. In Study 1, 402 university students completed a (...) questionnaire inquiring about the want or desire to perform behaviors “at the present moment (right now).” Items related to physical activity (e.g., “move my body”) and sedentary behaviors (e.g., “do nothing active”). An exploratory structural equation model (ESEM) revealed that 10 items should be retained, loading onto two factors (5 each for Move and Rest). In Study 2, an independent sample (n= 444) confirmed these results and found that Move and Rest desires were associated with stage-of-change for exercise behavior. In Study 3, 127 community-residing participants completed the CRAVE at 6-month intervals over two years- two times each session. Across-session interclass correlations (ICC) for Move (ICC = 0.72–0.95) and Rest (ICC = 0.69–0.88) were higher than when they were measured across 24-months (Move: ICC = 0.53; Rest: ICC = 0.49), indicating wants/desires have state-like qualities. In Study 4, a maximal treadmill test was completed by 21 university students. The CRAVE was completed immediately pre and post. Move desires decreased 26% and Rest increased 74%. Changes in Move and Rest desires were moderately associated with changes in perceived physical fatigue and energy. In Study 5, 41 university students sat quietly during a 50-min lecture. They completed the CRAVE at 3 time points. Move increased 19.6% and Rest decreased 16.7%. Small correlations were detected between move and both perceived energy and tiredness, but not calmness or tension. In conclusion, the CRAVE scale has good psychometric properties. These data also support tenets of the WANT model of motivation states for movement and rest (Stults-Kolehmainen et al., 2020a). Future studies need to explore how desires to move/rest relate to dynamic changes in physical activity and sedentarism. (shrink)

Progress in elementary particle physics in recent decades has changed the status of the visible phenomena in the context of scientific research. Empiricist positions in philosophy of science, which put particular emphasis on the pre-eminence of the visible regime, are affected by this development. In spite of its less radical claims, constructive empiricism turns out to run into more serious problems than straightforward instrumentalism. The constructive empiricist’s emphasis on the scientist’s aims makes it essential for her to provide a satisfactory (...) motivation for scientific inquiry. This, however, seems difficult to achieve on an empiricist basis in the case of elementary particle physics. (shrink)

Steen Brock paints a cross-disciplinary picture of the philosophical and scientific background for the rise of the quantum theory. He accounts for the unity of Kantian metaphysics of Nature, the Helmholtzian principles, and the Hamiltonian methods of modern pre-quantum physics. Brock shows how Planck's vision of a generalization of classical physics implies that the original quantum mechanics of Heisenberg can be regarded as a successful attempt to maintain this modern unity of physics.However, for Niels Bohr, the unity of science and (...) metaphysics did not end in the world of physics. The development of quantum physics had general implications both for other sciences and for various philosophical issues. Brock discusses these matters with respect to recent topics within the philosophy of science and major interpretations of Bohr's ideas. The author invites the reader to follow a long andwinding route of thought which, in the end, culminates in Bohr's ideas of complementarity, culture and Spirit. (shrink)

Overall, there’s a rich literature on free speech and hate speech. However, there’s been comparatively less discussion on hate speech that brings in empirical psychological and medical evidence on the possible health harms hate speech can have for minorities. I introduce and piece together a set of pre-existing scientific data that’s new to the philosophical literature to help sufficiently establish an argument that governments should ban hate speech. Given the adverse effects hate speech can have on one’s mental and (...) class='Hi'>physical health, hate speech causes harm at many times. Since it causes such harm and leads to overridingly negative consequences, the government ought to regulate such speech. (shrink)

Is materialism right to claim that the world of everyday-life experience – the phenomenal world – is nothing but an illusion produced in physical reality, notably in the brain? Or is Merleau-Ponty right when he defends the fundamental character of the phenomenal world while rejecting physical realism? I address these questions by exploring the nature of the body proper in Merleau-Ponty and Plessner, arguing that physical and phenomenal realism are not mutually exclusive but complementary. The argument includes (...) a close examination of the relationships between scientific and pre-scientific perspectives, between living and non-living things, and between humans and animals. (shrink)
