Identifying optimal ways of organizing exploration in particle physics mega-labs is a challenging task that requires a combination of case-based and formal epistemic approaches. Data-driven studies suggest that projects pursued by smaller master-teams are substantially more efficient than larger ones across sciences, including experimental particle physics. Smaller teams also seem to make better project choices than larger, centralized teams. Yet the epistemic requirement of small, decentralized, and diverse teams contradicts the often emphasized and allegedly inescapable logic of discovery that forces (...) physicists pursuing the fundamental levels of the physical world to perform centralized experiments in mega-labs at high energies. We explain, however, that this epistemic requirement could be met, since the nature of theoretical and physical constraints in high energy physics and the technological obstacles stemming from them turn out to be surprisingly open-ended.

We argue that Bohrian complementarity is a framework for making new ontological sense of scientific findings. It provides a conceptual pattern for making sense of the results of an empirical investigation into new realms or fields of natural properties. The idea of “formation length” engenders this mutual attunement of evidence and reality. Physicists want to be able to ascribe ontological features to atomic constituents and atomic processes such as “emission”, “impact”, or “change of energy-state”. These expressions supposedly refer to “local” (...) forms of physical change that in sum constitute the possibility of there being a “global” (for example an atomic) system of possible states. We argue that it is only because we can act it out in the design of experiments that we canmake sense of the link between classical and quantum theoretical systems. We need the notion of formation length in order to express the principle that the atom is a causal unity. This not in the sense of being the ground for a particular kind of causality, but in the sense of unifying the grounds for the variety of causal manifestations that constitutes the atom. (shrink)

This is a chapter from my book Perception (Routledge). I explain the physical state view of sensory experience (Papineau, McLaughlin, others). I criticize an argument against it based on the "transparency observation". Then I develop two alternative arguments against it. The first is a Leibniz's Law argument based on the essentially externally directed character of some experiences. The second concerns "brains in vats". Finally I consider a recent response due to David Papineau, which involves rejecting essential external directedness.

Sometimes conducting an experiment to ascertain the state of a system changes the state of the system being measured. Kahneman & Tversky modelled this effect with ‘support theory’. Quantum physics models this effect with probability amplitude mechanics. As this paper shows, probability amplitude mechanics is similar to support theory. Additionally, Viscusi's proposed generalized expected utility model has an analogy in quantum mechanics.

This book offers a phenomenological conception of experiential justification that seeks to clarify why certain experiences are a source of immediate justification and what role experiences play in gaining (scientific) knowledge. Based on the author's account of experiential justification, this book exemplifies how a phenomenological experience-first epistemology can epistemically ground the individual sciences. More precisely, it delivers a comprehensive picture of how we get from epistemology to the foundations of mathematics and physics. The book is unique as it utilizes (...) methods and insights from the phenomenological tradition in order to make progress in current analytic epistemology. It serves as a starting point for re-evaluating the relevance of Husserlian phenomenology to current analytic epistemology and making an important step towards paving the way for future mutually beneficial discussions. This is achieved by exemplifying how current debates can benefit from ideas, insights, and methods we find in the phenomenological tradition. (shrink)

The scales across which physical properties exist are vast and subtle in their effects on particular systems placed locally on such scales. For example, human experiential access is restricted only to partial segments of the mass density, size, and temperature scales of the universe. I argue that philosophers must learn to appreciate better the effects of physical scales. Specifically, thought experiments in philosophy should be more sensitive to physical scale effects, because the conclusion of a thought experiment (...) may be undermined by unintentionally ignored scale effects, and the changes required to obtain the foreground state of affairs in a thought experiment might require unacknowledged scale-spanning changes to the contextual background. I discuss four philosophical thought experiments: Putnam's Twin Earth and Brain in a Vat, Searle's Chinese Room, and Chalmers's Zombies Without Qualia. I close by briefly defending the greater interest and importance of physical possibility over logical possibility. (shrink)

BackgroundMedical disputes, medical disturbances, verbal and physical violence against physicians, and burnout have reached epidemic levels. They may negatively impact both physicians and the healthcare system. The experience of medical disputes, medical disturbances, verbal, and physical violence, and burnout and the correlates in physicians working in public hospitals in China needed to be investigated.MethodsA nationwide cross-sectional survey study was conducted between 18 and 31 March 2019. An anonymous online questionnaire was administered. The questionnaire included the 22-item Maslach (...) Burnout Inventory-Human Services Survey. We also collected data on demographic and job-related factors, as well as physicians’ experiences of medical disputes, medical disturbances, verbal and physical violence from patients and the patients’ family members.FindingsIn total, 22,213 physicians from 144 tertiary public hospitals in all of China’s 31 provinces completed the survey. The overall burnout rate among the surveyed physicians was 31.28%. Moreover, 33.48% of physicians experienced disputes, 20.86% experienced disturbances, 48.52% experienced verbal violence, and 5.84% experienced physical violence in the past 12 months. Factors found to be significantly associated with burnout included younger age, being divorced or widowed, having a lower educational background, working in internal medicine departments, longer working hours per day, working in general hospitals, being in East China, as well as having experienced disputes, disturbances, and physical and verbal violence.InterpretationClose to a third of the Chinese doctors working in the tertiary hospitals reportedly experienced burnout, and the problem is related to the unsafe working environment caused by the worsening doctor-patient relationship.

Modern physics is founded on two mainstays: mathematical modelling and empirical verification. These two assumptions are prerequisite for the objectivity of scientific discourse. Here we show, however, that they are contradictory, leading to the ‘experiment paradox’. We reveal that any experiment performed on a physical system is—by necessity—invasive and thus establishes inevitable limits to the accuracy of any mathematical model. We track its manifestations in both classical and quantum physics and show how it is overcome ‘in practice’ via the (...) concept of environment. We argue that the unravelled paradox induces a new type of ‘ontic’ underdetermination, which has deep consequences for the methodological foundations of physics. (shrink)

Mere physical experiences of warmth, distance, hardness, and roughness are found to activate the more abstract psychological concepts that are analogically related to them, such as interpersonal warmth and emotional distance, thereby influencing social judgments and interpersonal behavior without the individual's awareness. These findings further support the principle of neural reuse in the development and operation of higher mental processes.

For quantum systems, whose energy ratios En/E0 are integers, and |E0| is the smallest energy, the time dependent wavefunctions and expectation values of time independent operators have time periodicitiy with a time period T equal to T = h/|E0|, where h is the Planck constant. This periodicity is imposed on the wavefunctions due to undersampling in energy, but following a similarity with aliasing in signal analysis, it may allow to probe future and past events under the condition that our world (...) is in reality a true four-dimensional, “static” space–time. We suggest an experiment to test that possibility. A positive result will indicate that we live in a four-dimensional space–time. A negative result (not getting signals from the future) will indicate that four-dimensional space–time is not physical one and that we live in a three-dimensional space with a time. (shrink)

Strawson’s challenging and provocative defence of panpsychism1 begins by sensibly insisting that physicalism, properly understood, must unflinchingly countenance the occurrence of conscious experiences. No view, he urges, will count as ‘real physicalism’ (p. 4) if it seeks to get around or soften that commitment, as versions of socalled physicalism sometimes do. Real physicalism (hereinafter physicalism tout court) must accordingly reject any stark opposition of mental and physical, which is not only invoked by many followers of Descartes, but even countenanced (...) by many recent physicalists. Conscious experiences, Strawson persuasively urges, are a special case of the physical, just as cows are animals. Panpsychism enters the picture because, despite the physical nature of conscious experiences, Strawson maintains that we cannot describe or explain the experiential using the terms of physics or neurophysiology. Since the experiential is nonetheless physical, Strawson concludes that the physical ultimates must, in addition to whatever properties physics and neurophysiology reveal, have experiential properties as well. Strawson argues that we cannot avoid this conclusion by maintaining that combinations of physical ultimates constitute or give rise to experiential properties. Physical ultimates cannot give rise to conscious experience unless those ultimates are themselves in some way ‘intrinsically experiential’ (p. 22). The experiential cannot emerge from nonexperiential ultimates in the way that macroscopic liquidity is standardly held to emerge from molecular properties. Strawson concludes that at least some physical ultimates must be ‘intrinsically experience-involving’ (p. 22); and, since it’s reasonable to see the physical ultimates as homogeneous in nature, we should assume that they all have experiential properties.

I consider an argument, due to Geoffrey Lee, that we can know a priori from the left-right asymmetrical character of experience that our brains are left-right asymmetrical. Lee's argument assumes a premise he calls relationism, which I show is well-supported by the best philosophical picture of spacetime. I explain why Lee's relationism is compatible with left-right asymmetrical laws. I then show that the conclusion of Lee's argument is not as strong or surprising as he makes it out to be.

Abstract Thought experimentation is part of accepted scientific practice, and this makes it surprising that philosophers of science did not seriously engage with it for a very long time. The situation changed in the 1990s, resulting in a highly intriguing debate over thought experiments. Initially, the discussion focused mostly on thought experiments in physics, philosophy, and mathematics. Other disciplines have since become the subject of interest. Yet, nothing substantial has been said about the role of thought experiments in nonphilosophical theology. (...) This paper discusses the role of thought experiments in Christian theology in comparison to their role in quantum physics, as mentioned by John Polkinghorne in Quantum Physics and Theology. We first look briefly at the history of the inquiry into thought experiments and then at Polkinghorne's remarks about the role of thought experimentation in quantum physics and Christian eschatology. To determine the actual importance of thought experiments in Christian theology a number of new examples are introduced in a third step. In the light of these examples, in a fourth step, we address the question of what it is that explains the cognitive efficacy of thought experiments in quantum physics and Christian theology.

The original accounts of twenty-four experiments that created modern physics, retaining the original illustrations where possible.

Leaving aside here the question of the author of the Essai de logique, I show that, if Mariotte insisted on the specificity of physics, he also sought a certain inspiration in mathematics as to the way in which to lay out the propositions in a proof. To do so, I start off from the ontological distinction made in the Essai among three types of possibles; next we will show that the three types of propositions correspond to three types of knowledge, (...) and, correlatively, that the main problem of physics is that it is impossible to establish in a certain fashion universal sensory propositions; I next characterize the notion of principles of experience; finally, I examine a bit systematically the relationship between mathematics and physics.

Every metaphysical system must take something as fundamental and unanalyzed, something to which everything else ultimately reduces. Most philosophers today prefer to conceive fundamental reality as non-mental and categorical. This leaves them seeking to reduce the mental to the non-mental and the dispositional to the categorical. Pelczar proposes to invert this picture, putting experience and chance at the foundation and attempting to explain the non-mental and categorical features of our world in their terms. The resulting view, which he calls (...) phenomenalism, takes physical objects to be possibilities (or tendencies) for experience. (shrink)

Conscious experience has been said to be outside of, or alien to, physics, and unexplained in a physical world. However, it is argued here that experience is entirely expected in a physical world that can only be defined by its power to determine patterns of experience. Something physical is something with the type of causal power that can contribute to determining the content of an experience if a subject is present at the right (...) place and time. Physical powers also interact with other physical powers, distant from any given subject, to form chains, and it is these interactions that physics handles mathematically. Nevertheless, actual causation is always defined by reference to determination of experience. The apparent puzzle of why there should be a link between experience and the physical may relate in part to the fact that experience is always immediately causally proximal, always 'here and now', at least as far as we can ascertain. Proximality, and with it the potential for mentality, cuts across existential/ ontological categories. Experience also requires a concept of an intrinsic individual, in order for there to be individual points of view. The practical problem for consciousness studies is to identify intrinsically individual causal units with event domains in human brains, that can have points of view and content that could fit with human experiences, in a way consistent with current physics. It is suggested that the 'causal diamond' concept of the here and now explored by Savitt (2015) and Arthur (2019), together with principles of field theory, may provide a useful starting point.

ObjectiveTo examine how physical and psychological childbirth experiences affect maternal perceptions and experiences of early infant behavioural style.BackgroundUnnecessary interventions may disturb the normal progression of physiological childbirth and instinctive neonatal behaviours that facilitate mother–infant bonding and breastfeeding. While little is known about how a medicalised birth may influence developing infant temperament, high impact interventions which affect neonatal crying and cortisol levels could have longer term consequences for infant behaviour and functioning.MethodsA retrospective Internet survey was designed to fully explore maternal (...) experiences of childbirth and her postnatal perceptions of infant behaviour. Data collected from 999 mother–infant dyads were analysed using Pearson’s correlations and multiple analyses of covariance, employing the Bonferroni method of correction to establish initially significant variables. Multiple linear regressions were conducted to determine major perinatal contributors to perceived early infant temperament.ResultsMultiple regression analyses on each of the eight Mother and Baby Scales outcome variables indicated that early infant behavioural style was largely predicted by subjective maternal states during and post-childbirth, postnatal depression scores, maternal personality traits and infant age. For example, infant age was the most significant predictor of Alert-Responsive infant behaviour, followed by maternal Postnatal Positive experience. In contrast, depression scores were the most significant predictor of Unsettled-Irregular infant behaviour, followed by Anxious-Afraid Birth Emotions and infant age. Mothers also perceived their infants as more Alert-Responsive and Easier overall after a Supported birth experience.ConclusionMaternal and infant outcomes were influenced by multiple physical and psychological perinatal variables. The mother’s subjective experience appeared to be of equal significance to more objective factors. Social support enhanced the mother’s childbirth experience, benefitting her perceptions of her baby’s early temperament. These findings provide further support for current World Health Organisation intrapartum guidelines on the importance of making childbirth a ‘positive experience’ for women. (shrink)

When philosophers of science relate Kant‘s theory of nature to modern physics, they neglect the critical parts of the Critique of Pure Reason. My paper focuses on the way in which Kant wanted to demonstrate the limitations of physical knowledge by means of the cosmological antinomy. According to Kant, cosmology gives rise to four variations of one-and-the-same antinomy of pure reason. He wanted to show that any attempt to complete our spatio-temporal or dynamical knowledge of the world is based (...) on a self-contradictory world view. Obviously he criticized the cosmological debates of his day whose topics are obsolete in our days. However, his doctrine of the antinomy of pure reason has a rationale which concerns the foundations of physics in Kant’s day as well as in ours. After giving a sketch of the subjects and of the structure of Kant’s antinomy, I present four variations on the theme "experience and completeness in physical theory" from a modern point of view. The fourth variation will indeed yield a conflict between the claims of completeness and the finite conditions of possible experience within physics which captures the rationale of Kant’s antinomy. Finally, I try to point out briefly how this rationale relates to Kant’s distinction of phenomena and noumena, and how this distinction can be re-interpreted in the context of modern physics. Indeed Niels Bohr made a similar distinction when he developed the Copenhagen interpretation of quantum mechanics. (shrink)

A literature search indicates an absence of research into boy’s experiences of physical education in classes in which there is a significant majority of girls. The aim of the study was to examine how boys in such classes experience their PE lessons. The methodological approach was qualitative, and data were collected with interviews of 13 boys in classes with more than 90% girls at a Norwegian high school. The data were analyzed with QSR NVivo 10, focused on creating (...) categories of meaning, in which students’ experiences were taken as subjectively true. The data are based on subjective constructions, which students constructed as part of their own interpretations and reflections on what had occurred in PE at the school. Results of the study came out in the form of three main findings. Two of those relate to a negative experience and the third to a positive experience of PE. The boys mostly felt that they are physically superior and have to consider the girls. Furthermore, the boys reported little challenge and feelings of mastery while being together with passive girls who are allowed to choose the activities. However, the boys found it easier to show off in front of the teachers and classmates when there were just a few boys in the class. The results are discussed in relation to gender-related theory on how the respondents are producing a traditional male gender in PE through their mastery, strength, and ambition to compete. We suggest a new approach of teaching that is more student-centered. A strategy could be to include other activities than sport-based activities into PE – activities that do not require strength and other athletic skills leading to feelings of hegemonic masculinity. A larger focus on social interactions during PE classes – activities in which students’ sex is not as important as in traditional teacher- and sport-centered PE classes, may be a good strategy.

I tend to think of myself as bodily. Probably, so do you. Philosophically this takes some explaining. A candidate explanation is this: The bodily self is a physical agent. Knowledge of oneself as bodily is fundamentally knowledge of oneself as agentive; such knowledge is grounded in both experience of oneself as instantiating a bodily structure that affords a limited range of actions; and experience of oneself as a physical agent that tries to perform a limited range (...) of actions over time. By contrast René Descartes famously argued that all self-knowledge is grounded in, and cannot extend beyond, knowledge of oneself as a mental entity. If correct this would preclude the possibility of any knowledge of a bodily self, for such a thing would ex hypothesi not exist. Accordingly, this dissertation serves a dual purpose: to demonstrate why a Cartesian theory of self-knowledge is no threat to an account of bodily self knowledge; and to provide such an account. This dual purpose is achieved over the course of three chapters. The first chapter will set up the remaining two, by introducing the notion of self-identifying judgements, providing an argument in favour of bodily self knowledge on its basis, and noting two failures of this argument in light of a Cartesian response. The second and third chapter are respective attempts to address these two failures. The second chapter is explicitly concerned with the Cartesian, but is overall devoted to giving an account of the relationship between bodily experience and action. The third chapter is more programmatic, comprising a consistent set of suggestions concerning the sense of agency and its role in an account of bodily self knowledge. (shrink)

Chronically disabling health impairments affect an increasing number of people worldwide. In close relationships, disability is an interpersonal experience. Psychological distress is thus common in patients as well as their spouses. Dyadic coping can alleviate stress and promote adjustment in couples who face disabling health impairments. Much research has focused on dyadic coping with cancer. However, other health problems such as physical and sensory impairments are also common and may strongly impact couple relationships. In order to promote couples' (...) optimal adjustment to impaired health, the identification of disability-related relationship challenges is required. Furthermore, ways in which dyadic coping with these challenges may benefit couples could inform researchers and practitioners how to support couples in coping with health impairments. Accordingly, the aims of this study were to systematically review dyadic challenges and dyadic coping when one partner has a chronically disabling physical or sensory impairment. Out of 873 articles identified through database searches, 36 studies met inclusion criteria. The disability-related dyadic challenges identified in the review were changed roles and responsibilities within the couple, altered communication, compromised sexual intimacy, and reduced social participation. These challenges were reported to burden both partners and the couple relationship. Dyadic adjustment benefitted from a we-perspective, i.e., when couples viewed the disability as a shared challenge and engaged in conjoint dyadic coping. The results suggest that patient/care recipient and partner/caregiver roles should be de-emphasized and that disability should be recognized as an interpersonal experience. (shrink)

In the ten years following the publication of Galileo Galilei's Discorsi e dimostrazioni matematiche intorno a due nuove scienze , the new science of motion was intensely debated in Italy, France and northern Europe. Although Galileo's theories were interpreted and reworked in a variety of ways, it is possible to identify some crucial issues on which the attention of natural philosophers converged, namely the possibility of complementing Galileo's theory of natural acceleration with a physical explanation of gravity; the legitimacy (...) of Galileo's methods of proof and of his theory of the composition of continuous magnitudes; and the adequacy of the experimental evidence in favor of his theory.Through his published works and his correspondence, Marin Mersenne contributed in a significant way to each of these discussions. In the following, I shall provide a sketch of Mersenne's multiple engagement with the new science of motion, while trying to account for his growing skepticism concerning Galileo's law of free fall. Whereas in the 1630s, Mersenne still firmly believed in the validity of this law and tried to devise experimental and mathematical proofs in its favor, in the 1640s he developed serious doubts regarding the possibility of constructing an exact science of motion. As we shall see, Mersenne's evolving attitude sheds an interesting light on his views concerning the relation between physics and mathematics.---------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------- ----------------------------------------------------.

Science should tell us what the world is like. However, realist interpretations of physics face many problems, chief among them the pessimistic meta induction. This book seeks to develop a realist position based on process ontology that avoids the traditional problems of realism. Primarily, the core claim is that in order for a scientific model to be minimally empirically adequate, that model must describe real experimental processes and dynamics. Any additional inferences from processes to things, substances or objects are not (...) warranted, and so these inferences are shown to represent the locus of the problems of realism. The book then examines the history of physics to show that the progress of physical research is one of successive eliminations of thing interpretations of models in favor of more explanatory and experimentally verified process interpretations. This culminates in collections of models that cannot coherently allow for thing interpretations, but still successfully describe processes. (shrink)

Immanuel Kant famously thought that the presuppositions of Newtonian physics are the necessary conditions of the possibility of experience in general – both “outer” and “inner” experience. Today we know, of course, that Newtonian physics only applies to a limited domain of physical reality and is radically inadequate in the quantum and relativistic domains. This gives rise to an interesting question: could the radical changes in physics suggest new conditions for the possibility of experience? In other (...) words, does post-Newtonian physics suggest a post-Kantian view of human experience? (shrink)

The paper analyzes early colonial representations of the New World, connected with immigration of the first- and second-generation religious dissenters in what was to become America. Taking into account the well-documented influence of Puritans on American identity, the paper elaborates on the Puritans’ and Pilgrims’ mindsets as they arrived in the New World, connected not only with their religious beliefs but most of all with a practical need to organize themselves effectively. Be it in John Winthrop’s “A Modell of Christian (...) Charity,” William Bradford’s “Of Plymouth Plantation” or Samuel Danforth’s “New England’s Errand into the Wilderness,” the authors of these works clearly show how the Pilgrims and Puritans had to confront the experience of emigration/immigration and construct not only new ways of social organization but also new identity. The paper focuses on the immigrants’ perception of the New World, their own role and challenges they were faced with, and their thinking about the society they came from and were about to construct. It deals with their process of adjusting to the surroundings and discussing values they decided to promote for the sake of communal survival in the adverse conditions of the New World. (shrink)
