This chapter provides a few approaches aiming to review the interpretation of matter, nature and the universe by trying to reframe the physical sciences in the context that has taken shape: arrangement, communication and information. In relation to what has just been presented, action regards more a mechanical type of physics with forces, arrangement, movements and orientations. Rational mechanics is the result. The existence of the two types of physics is associated with two great scientists. First of all, (...) Galileo, who established the principle of relativity and the addition of velocities by perfecting mathematical physics. Second, Planck, who elaborated the famous formula “E = hv” to account for blackbody radiation. If the distinction between a physics of communication and a physics of arrangement is applicable, then it must be validated in quantum theory and the description of the universe. Classical mechanics and relativistic cosmology describe arrangements of matter. Quantum physics describes communications. (shrink)

In physics, mass is a property of matter that describes how material elements are arranged in space and opposed to forces, and also how they generate forces such as gravitation forces. Electric charge remains enigmatic. This charge is a universal constant, and it is discrete rather than continuous. Spin can be interpreted as a reversal movement that allows the outer side of matter to fold back on itself. Finally, Maxwell's theory on the propagation of light also belongs to the (...) physics of information. Relativistic cosmology does not easily lend itself to an interpretation that reveals the dynamics of communication. It is conceived in its principle as a physics of arrangements. Einstein completes modern physics, where "completes" must be considered in a broad sense. One of the key questions concerns the link between mathematics and physical things or, in other words, what is represented and "what is" or "happens" in the world. (shrink)

Analyses of Theories and Methods of Physics and Psychology was first published in 1970. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions.This is Volume IV of the Minnesota Studies in the Philosophy of Science, a series published in cooperation with the Minnesota Center for Philosophy of Science at the University of Minnesota and edited by Herbert Feigl and Grover Maxwell. Dr. Feigl was (...) the director of the Center.In a preface to the first volume in the series, Professors Feigl and Michael Scriven noted the extensive concern of the Center with "the meaning of theoretical concepts as defined by their locus in the 'nomological net' and the related rejection of the reductionist forms of operationism and positivism." In this volume, several contributors are again concerned with philosophical, logical, and methodological problems of psychology. As before, some papers deal with broad philosophical issues, others with more specific problems of method or interpretation. However, a deep concern for logical and methodological problems of special relevance to the physical sciences is reflected in a number of essays.The contents are arranged in two sections, the first part being based on the papers and discussion from a conference held at the Center on the problems of correspondence rules. Contributors are Herbert Feigl, Paul K. Feyerabend, N.R. Hanson, Carl G. Hempel, Mary Hesse, Grover Maxwell, and William Rozeboom. The second group of essays, by various members of the staff of the Center and some of its visitors, reflects current issues and controversies of great interest. The contributors are William Demopoulos, Keith Gunderson, Paul E. Meehl (three essays), and Michael Radner. (shrink)

Fiction involves exploring imaginative arrangements of places and characters: elements that can be recognized by readers. In childhood, exploration occurs from a safe home base of a caregiver; fiction enables a comparable basis. Physical elements in fiction are settings. More important are social explorations: transactions with characters that can include transformation. This is illustrated by Alice's Adventures in Wonderland.

Quantum mechanics, and classical mechanics, are framework theories that incorporate many different concrete theories which in general cannot be arranged in a neat hierarchy, but discussion of ‘the ontology of quantum mechanics’ tends to proceed as if quantum mechanics were a single concrete theory, specifically the physics of nonrelativistically moving point particles interacting by long-range forces. I survey the problems this causes and make some suggestions for how a more physically realistic perspective ought to influence the metaphysics of quantum (...) mechanics. (shrink)

This article will derive a definition and account of the physically educated person, through an examination of the philosophy of Andrew Reid, Richard Peters and Aristotle. Initially, Reid’s interpretation of Peters’ views about the educational significance of practical knowledge (and physical education) will be considered. While it will be acknowledged that Peters was rather disparaging about the educational merit of some practical activities in Ethics and Education, it will be argued that he elsewhere suggests that such practical activities could be (...) educationally worthwhile in and of themselves. In Education and the educated man he specified that practical activities should be regarded as educationally important if they are either transformed by theoretical understanding and/or pursued to the point of excellence. In suggesting that education involves the cultivation of both theoretical and practical human excellences it is argued that Peters’ philosophy of education begins to take on a more Aristotelian bent. After exploring Aristotle’s notion of virtue (human excellence) and his discussion of physical training in The politics, it is claimed that physical education activities might be most worthwhile when they extend the moral habits and/or modes of thought of pupils, towards excellence. It is concluded that physically educated persons should be defined as those who have learned to arrange their lives in such a way that the physical activities they freely engage in make a distinctive contribution to their long-term flourishing.

This study explored the lived experience of security and contentment, and their absence, for latency-aged children living in shared-time parenting arrangements following their parents’ separation. A descriptive phenomenological methodology was utilized. Sixteen children living in shared-time were interviewed about their experiences of two phenomena: “feeling secure and content living in shared-time” and “not feeling secure and content living in shared-time.” The eight richest protocols were selected for analysis. The two resultant general structures and their core constituents are presented, and (...) individual variations discussed. Central to each phenomenon is the parent/s’ capacity, or incapacity, to create and sustain a physical and emotional space in which the child feels secure and held in the mind, feels the arrangements are responsive to their needs, feels free to access the “absent” parent, and experiences integration between the two parental homes. Implications for phenomenological human science research are considered, including the use of descriptive phenomenology with children. (shrink)

It is proposed that the physical structure of an observer in quantum mechanics is constituted by a pattern of elementary localized switching events. A key preliminary step in giving mathematical expression to this proposal is the introduction of an equivalence relation on sequences of spacetime sets which relates a sequence to any other sequence to which it can be deformed without change of causal arrangement. This allows an individual observer to be associated with a finite structure. The identification of suitable (...) switching events in the human brain is discussed. A definition is given for the sets of sequences of quantum states which such an observer could occupy. Finally, by providing an a priori probability for such sets, the definitions are incorporated into a complete mathematical framework for a many-worlds interpretation. At a less ambitious level, the paper can be read as an exploration of some of the technical and conceptual difficulties involved in constructing such a framework. (shrink)

As the dialogue between science and religion has grown more robust, Christians have been led to more nuanced ways of thinking about the connections between these two modes of inquiry. This essay focuses on exploring various deficiencies in naturalistic conceptions of the cosmos, and further exploring how Eastern Orthodox theology provides a more encompassing picture of human beings and their place in the cosmos.

entry for the Stanford Encyclopedia of Philosophy (SEP) This entry will attempt to provide a broad overview of the central themes of Leibniz’s philosophy of physics, as well as an introduction to some of the principal arguments and argumentative strategies he used to defend his positions. It tentatively includes sections entitled, The Historical Development of Leibniz’s Physics, Leibniz on Matter, Leibniz’s Dynamics, Leibniz on the Laws of Motion, Leibniz on Space and Time. A bibliography arranged by topic is (...) also included. A working draft is available here (comments, as always welcome): draft. (shrink)

This second edition of Basic Data of Plasma Physics is, in essence, a new book, for several reasons. First, so voluminous have been the research results in this area since the first edition of 1959 that the basic data themselves are greatly changed and enlarged. Second, whereas the earlier edition presented much of the material in verbal form, this one displays almost all of it in a consistent set of graphic figures. And, finally, this new edition is one of (...) the first implementations of computer-based information transfer, in which the basic data were searched out by means of a remote console tied into a central disk library containing an extensive collection of bibliographic information on physics literature.This last matter deserves further amplification, since the new techniques employed here are likely to be used more and more often in the future--because of the ever more rapidly expanding volume of research results just mentioned. Professor Brown, writing in Physics Today, summarizes his aims and methods:Any collection of data one can make these days is out of date before it is published. This is true, for example, of my Basic Data of Plasma Physics. In the book I tried to bring together in useful form the data of gaseous electronics and plasma physics upon which scientists base calculations and further work with basic parameters.Updating this book seemed an ideal computer experiment. I used the Information Retrieval Service of the TIP program not only to find material that has come out since publication of the book but also to arrange the program so that the computer could continue in the future to retrieve relevant information....The Technical Information Project, upon which this experiment is based, has programmed 25 physics journals from the past few years and The Physical Review from 1959 onto the IBM 7094 operated by Project MAC. Project MAC uses a compatible time-sharing system that is available by standard telephone connections....The TIP program contains title, author, reference and entire bibliography of every article covered by the computer....Entrance into the TIP system is made by choosing a key word or words most likely to be contained in the title of an article in a specific subject....in the revision of Basic Data of Plasma Physics the material is created in an open-ended form so that anyone with access to the computer program can search the literature for material that will appear after the report is printed. This feature of the bibliographic search by computers provides a new dimension to the published literature in book form which, without this open-ended feature, is out of date quite generally long before the actual publication date.

This paper focuses on Leibniz’s conception of modality and its application to the issue of natural laws. The core of Leibniz’s investigation of the modality of natural laws lays in the distinction between necessary, geometrical laws on the one hand, and contingent, physical laws of nature on the other. For Leibniz, the contingency of physical laws entailed the assumption of the existence of an additional form of causality beyond mechanical or efficient ones. While geometrical truths, being necessary, do not require (...) the use of the principle of sufficient reason, physical laws are not strictly determined by geometry and therefore are logically distinct from geometrical laws. As a consequence, the set of laws that regulate the physical laws could have been created otherwise by God. However, in addition to this, the contingency of natural laws does not consist only in the fact that God has chosen them over other possible ones. On the contrary, Leibniz understood the status of natural laws as arising from the action internal to physical substances. Hence the actuality of physical laws results from a causal power that is inherent to substances rather than being the mere consequence of the way God arranged the relations between physical objects. Focusing on three instances of Leibniz’s treatment of contingency in physics, this paper argues that, in order to account for the contingency of physical laws, Leibniz maintained that final causes, in addition to efficient and mechanical ones, must operate in physical processes and operations.

This is a sophisticated, nontechnical introduction to the main issues in the philosophy of physics. It is exceptionally well-written. The issues are well-chosen, the prose are clear and concise, the text is organized into manageable sections arranged in a logical manner, and the treatment of various positions on the main issues is evenhanded. Also, each of the three central chapters is supplemented by an annotated bibliography that will serve well as a selective guide for motivated readers.

The moral permissibility of organ transplantation is taken for granted by most biomedical ethicists and practitioners. Of contemporary concern is not whether, but by what arrangements, we ought to allow organ transplantation. Should we institute markets for organs, thereby increasing their availability and saving many lives? Should organs be sold to the highest bidder? Should we allow the post mortem taking of organs without prior consent? Among moral theorists, the Kantians are suspected of being the least enthusiastic with respect (...) to these and similar questions. I will show the elements in Kant's theory that account for this lack of enthusiasm and how contemporary Kantians might answer questions about the permissibility of various arrangements for organ transplantation. I will argue that Kant would have had a permissive position on organ transplantation post mortem and a restrictive position on organ markets. These results will be based on a broader Kantian view of obligations to the body which stem from a non-formal theory of value. This non-formal theory, I will argue, is at the foundation of Kantian ethics. (shrink)

This book presents a collection of novel contributions and reviews by renowned researchers in the foundations of quantum physics, quantum optics, and neutron physics. It is published in honor of Michael Horne, whose exceptionally clear and groundbreaking work in the foundations of quantum mechanics and interferometry, both of photons and of neutrons, has provided penetrating insight into the implications of modern physics for our understanding of the physical world. He is perhaps best known for the Clauser-Horne-Shimony-Holt (CHSH) (...) inequality. This collection includes an oral history of Michael Horne's contributions to the foundations of physics and his connections to other eminent figures in the history of the subject, among them Clifford Shull and Abner Shimony. Among the editors and contributors are John Clauser and Anton Zeilinger, recipients of the Nobel Prize in Physics 2022. (shrink)

With over 150 alphabetically arranged entries about key scientists, concepts, discoveries, technological innovations, and learned institutions, the Oxford Guide to Physics and Astronomy traces the history of physics and astronomy from the Renaissance to the present. For students, teachers, historians, scientists, and readers of popular science books such as Galileo's Daughter, this guide deciphers the methods and philosophies of physics and astronomy as well as the historical periods from which they emerged. Meant to serve the lay reader (...) and the professional alike, this book can be turned to for the answer to how scientists learned to measure the speed of light, or consulted for neat, careful summaries of topics as complicated as quantum field theory and as vast as the universe. The entries, each written by a noted scholar and edited by J. L. Heilbron, Professor of History and Vice Chancellor, Emeritus, University of California, Berkeley, reflect the most up-to-date research and discuss the applications of the scientific disciplines to the wider world of religion, law, war, art and literature. No other source on these two branches of science is as informative or as inviting. Thoroughly cross-referenced and accented by dozens of black and white illustrations, the Oxford Guide to Physics and Astronomy is the source to turn to for anyone looking for a quick explanation of alchemy, x-rays and any type of matter or energy in between.

In selecting the papers for this volume I have excluded all physics papers proper. I have further omitted all book rev.iews. Instead, I have included two papers not published previously; they are marked by an asterisk (*) in the table of contents. Since many of the papers were occasioned by Symposia or similar gatherings their chronological order is rather accidental. Hence I have tried to group the papers thematically into four parts. Within each part the order of sequence is (...) from the more general to the more special, or from a more popular to a more technical treatment. The same principle has been applied to the sequential order of the parts. The foundational papers on quantum mechanics have been arranged in a somewhat dif ferent manner. Chapters XVI-XIX are concerned with the logic of complementarity while in Chapters XX-XXII a more radical recon ceptualization is carried out. Two of the older papers (Chapters VI and VIII) have been revised to bring them more into line with present terminology. Other papers have been corrected by additions and omissions. Additions are marked by square brackets [ ], while double square brackets [[ II signify omis sions or parts to be omitted. Hence [[A]] [B] means that 'A' should be replaced by 'B'. The heading of one paper (Chapter XX) has been changed to make it more descriptive. (shrink)

In recent decades, interest in the history and philosophy of the natural sciences has increased significantly. This interest has made scholars aware of the existing knowledge gap in these areas and has brought a kind of 'pressure' for more articles and books on the subject. Indeed, it also motivates academics to start new projects related to these disciplines. Volumes like this are much needed for scholars in the field, given the high amount of information they contain. This rich volume aims (...) at stimulating the field by presenting current research papers on Avicenna's influence on the fields of physics and cosmology. In order to achieve this goal, this work contains thirteen articles related to the reception of the Persian philosopher's thought in these areas in the Middle Ages. The book revolves around the three different languages and cultures which were crucial for the reception of Avicenna's thought. Hence, the volume is arranged in three main sections focusing on the Arabic, Hebrew and Latin traditions. It also contains an Index of Avicenna's Works with Passages Cited and an Index of Names. The introduction is rather short compared to other sections of the book. It covers the general topics presented in the volume. The first six chapters deal with the Arabic tradition ; the next two have to do with the Hebrew reception of Avicenna, and the last five analyse the Latin reception of Avicenna's physics and cosmology.

In 1922, Cartan introduced in differential geometry, besides the Riemannian curvature, the new concept of torsion. He visualized a homogeneous and isotropic distribution of torsion in three dimensions (3d) by the “helical staircase”, which he constructed by starting from a 3d Euclidean space and by defining a new connection via helical motions. We describe this geometric procedure in detail and define the corresponding connection and the torsion. The interdisciplinary nature of this subject is already evident from Cartan’s discussion, since he (...) argued—but never proved—that the helical staircase should correspond to a continuum with constant pressure and constant internal torque. We discuss where in physics the helical staircase is realized: (i) In the continuum mechanics of Cosserat media, (ii) in (fairly speculative) 3d theories of gravity, namely (a) in 3d Einstein-Cartan gravity—this is Cartan’s case of constant pressure and constant intrinsic torque—and (b) in 3d Poincaré gauge theory with the Mielke-Baekler Lagrangian, and, eventually, (iii) in the gauge field theory of dislocations of Lazar et al., as we prove for the first time by arranging a suitable distribution of screw dislocations. Our main emphasis is on the discussion of dislocation field theory. (shrink)

This article aims at reducing the gap between mathematics and physics from a Wittgensteinian point of view. This gap is usually characterized by two discriminating features. The propositions of physics assert something which might be false; they have a hypothetical character. On the contrary, since mathematical propositions are rules that condition the form of assertions, they remain immune from falsification. The propositions of physics refer to facts that may confirm or refute them. On the contrary, since mathematical (...) propositions have no meaning independently of the demonstration procedures, it cannot be said that they refer to “facts” that pre-exist demonstrations. If we take a closer look, however, these two differences fade away. On the one hand, the propositions of physics are more resistant to experimental tests than has been said in the wake of logical positivism. On the other hand, the “factual” empirical material is defined and co-constituted by instruments whose arrangement is determined by the theory to be tested. I conclude by discussing the possibility of a Wittgensteinian philosophy of contemporary physics. (shrink)

About the Series Contemporary philosophy of science combines a general study from a philosophical perspective of the methods of science, with an inquiry, again from the philosophical point of view, into foundational issues that arise in the various special sciences. Methodological philosophy of science has deep connections with issues at the center of pure philosophy. It makes use of important results, for example, in traditional epistemology, metaphysics and the philosophy of language. It also connects in various ways with other disciplines (...) such as the history and sociology of the sciences, with pure logic, and with such branches of mathematics as probability theory. These volumes are, for the most part, devoted to readings in the methodological aspects of the philosophy of science. One volume, however, takes up the philosophical issues in the foundations of a particularly important special science, that is the issues in the foundations of theories of contemporary physics. The methodological volumes cover a number of crucial general problem areas. The first volume takes up issues in the nature of scientific explanation, and the related issues of the nature of scientific law and of the casual relation among events. The second volume explores issues in the nature and structure of scientific theories. The third volume collects inquiries into the nature of scientific change, as one theory is replaced by another. Volume four is devoted to readings concerning the nature of probability and the nature and justification of inductive reasoning in science. The following volume continues the exploration of the issue of confirming and rejecting theories with a series of readings devoted to Bayesian methodologies in science and to the exploration of non-inductive strategies for rationalizing belief. Finally, volume six explores three major problem areas in the foundation of physics: the nature and rationale for physical theories of space and time; the interpretive problems arising out of the quantum theory; and some puzzles arising out of statistical mechanical theories of physics. The readings are selected and arranged to provide the user with systematic access to the most important contemporary themes in methodological philosophy of science and in philosophy of physics. The selections include many recent contributions to the field, as well as papers and extracts from books and journals otherwise not easily available. (shrink)

This study aims to determine the opinions of teachers of Religious Culture and Ethics Course (DKAB) about subject-based classroom application in-depth. The research has been carried from qualitative research methods with a case study design. In order to determine the working group of the study, criteria sampling was used in the first stage, and the maximum diversity sampling method was used in the next step. The sample of this research consists of 8 DKAB teachers working in Ankara province. A semi-structured (...) interview form has been used as a data collection tool in the study. The data of the qualitative of this research has been analyzed with both descriptive and content analysis by NVivo 10 program. In order to ensure validity and reliability in the study, credibility, transferability, consistency, and verifiability strategies have been used. When the research data were analyzed, four themes were formed: positive opinions about the application, negative opinions and problems related to the application, contribution of the practice to religious education and training, and recommendations about the application. DKAB teachers find the application more positive than the classroom system. It has been found that the practice of subject-based classrooms is a motivational tool for Primary School students, while it causes some problems for lower secondary school and upper secondary school students.Summary: Learning environments are among the key elements in the acquisition of 21st-century skills. Classrooms are also a part of the learning environment. Classes are the learning environment in which teachers and students spend most of their education and training process. In this context, subject-based classroom application is one of the preferred methods in the arrangement of classrooms.Subject-based classroom application means that the teachers have a special classroom related to their branches in the school building, and students attend the teacher's classroom according to the syllabus. In this practice, the teacher can decorate walls, floor, ceiling, column, and beam of the classroom with students’ study materials such as banner, poster, painting, cartoon to make the course more effective and efficient and to create a psychological atmosphere called classroom atmosphere-air.This application aims to activate the student by enriching the classroom and make learning effective and efficient. The classroom equipped with appropriate equipment and materials provides a favorable environment for the implementation of effective teaching strategies. The application can create “class/classroom culture” by using ordinary meanings and symbols related to the course. It provides students the opportunity to exhibit their products and contributes to students' self-regulation skills development. Besides, real-life practices or practices close to reality can be brought into the classroom. As a result, permanent learning can be realized with the possibility of creating a shared living space and the number of sensory organs participating in learning.This current study aims to address in-depth information about the opinions of Religious Culture and Moral Ethics (DKAB) teachers in primary, secondary, and high schools regarding the subject-based classroom application. When the studies in the literature are examined, it is seen that the studies related to the subject-based classroom application have increased since 2010. However, it is clear that this research is directed towards social studies, geography, science, and mathematics courses and is based on the opinions of students, teachers, and administrators at the secondary school level. In the context of DKAB course, there has been no research including the views of teachers, students, or school administrators regarding the application of subject-based classrooms. This study is carried out revealing perspectives of DKAB teachers by examining their opinions on the subject-based classroom application and contribute to the field. The research was conducted with a case study design from the qualitative research methods. The participants consist of 8 DKAB teachers working in Ankara province. A mixed purposive sampling method was used to determine the study group. In the first stage, the teachers implementing the DKAB classrooms application were taken as criteria. In the next step, the study group was determined within the framework of the maximum diversity sampling method by considering the variables such as school level, gender, age, education level, duration of teachers' work. The data were collected through a semi-structured interview form with expert opinion. In the form, there are nine main questions and probe questions, which include questions related to subject-based classrooms application, the contribution of the application to religious education and training, the contribution of teachers to professional and personal development, the effect of teachers' belonging to the school, the effectiveness, and improvement of the application. Permission has been obtained from the Ankara Provincial Directorate of National Education and participants via consent form for the interview. The interviews were recorded in audio, 169.58-minute audio recording transcripts, and 52-page interview data obtained. The qualitative data of this research has been analyzed with both descriptive and content analysis by NVivo 10 program. In order to ensure validity and reliability in the study, credibility, transferability, consistency, and verifiability strategies have been used.When the data of the research were analyzed, the opinions of DKAB teachers about the subject-based classrooms application categorized under four themes; positive and negative opinions/problems about the practice, the contribution of the practice to religious education and teaching and practical suggestions. Under the theme of positive opinions on the application, positive aspects for the teacher, student, parents, and comparison with the classroom system were formed. According to the participants, the practice of DKAB classroom is a “facilitation” element for the teacher because of the factors such as the teacher not moving around the classroom, not carrying material, having freedom to organize the classroom, and material regularity. In this application, since the teacher has a class of his own, the teacher adopts and owns the classroom and the sense of belonging to school increases. This sense of belonging is felt so strongly that there is even a participant who plans to retire if the application is abandoned. The positive aspects of the application for the students are that; a classroom is a motivating tool, the boards and walls can be used, and the student has the opportunity to exhibit their activities. When compared with the classroom system, it was stated that as a result of the branch classroom practice, the school equipment could be better protected, class order and cleaning easier, and the success of the students would be increased.The negative views of the participants on the application were grouped under the categories of students, teachers, and parents. Not having a fixed class of their own, continually relocating and losing time in recess, staying in the classroom door when the classroom is locked, not adopting the classroom and lack of lockers constitute the negative aspects of the application for the students. The overuse of classrooms, less use of teachers' rooms, lack of communication between colleagues are the negative aspects of the application for the teachers. It was stated by (75%) most of the participants that branch classroom application contributed to the continual learning of students in religious education and teaching. To make the application more functional, DKAB teachers have proposed arrangements such as improving physical infrastructure, enriching teaching materials, and arranging school syllabus and keeping classrooms open. As a result, teachers find the application more positive than the classroom system. While it is a motivation tool for primary school students, it causes some problems for secondary and high school students, such as carrying bags, staying at the door, and wasting time. In this sense, the application is recommended to be applied in primary schools that have a sufficient number of classrooms. Also, the system should be applied in secondary and high schools where the number of students is low, or the number of classrooms is sufficiently provided that the problems experienced by the students are eliminated. School administrations and teachers need to take necessary measures to make the application effective and efficient. (shrink)

As one of the earliest Western physics teachers, Richard Rufus of Cornwall helped transform Western natural philosophy in the 13th century. But despite the importance of Rufus's works, they were effectively lost for 500 years, and the Physics commentary is the first complete work of his ever to be printed. Rufus taught at the Universities of Paris and Oxford from 1231 to 1256, at the very time when exposure to Aristotle's libri naturales was revolutionizing the academic curriculum; indeed (...) Rufus gave the earliest surviving lectures on physics and metaphysics. Rufus's challenges to the views of Aristotle and the commentator Averroes proved to be enormously influential: his accounts of projectile motion, the place of the heavens, and creation, were to be taken up by the likes of Franciscus de Marchia, Roger Bacon, Thomas Aquinas and Bonaventure.

Theory reduction is analyzed and examples are presented from various branches of physics. The procedure takes different forms in different theories. Examples from various theories are arranged in increasing order of difficulty. Special emphasis is placed on the quantum to classical reduction. It is argued that there is good and interesting physics in theory reduction and that it deserves more attention than it has been receiving in the past.

A simple argument proposes a direct link between realism about quantum mechanics and one kind of metaphysical holism: if elementary quantum theory is at least approximately true, then there are entangled systems with intrinsic whole states for which the intrinsic properties and spatiotemporal arrangements of salient subsystem parts do not suffice. Initially, the proposal is compelling: we can find variations on such reasoning throughout influential discussions of entanglement. Upon further consideration, though, this simple argument proves a bit too simple. (...) To get such metaphysically robust consequences out, we need to put more than minimal realism in. This paper offers a diagnosis: our simple argument seems so compelling thanks to an equivocation. The predictions of textbook quantum theory already resonate with familiar holistic slogans; for realists, then, any underlying reality, conforming to such predictions, also counts as holistic in some sense or other, if only by association. Such associated holism, though, does not establish the sort of specific, robust supervenience failure claimed by our simple argument. While it may be natural to slide to this stronger conclusion, facilitating the slide is not minimal realism per se but an additional explanatory assumption about how and why reality behaves in accordance with our theory: roughly, quantum theory accurately captures patterns in the features and behaviors of physical reality because some underlying metaphysical structure constrains reality to exhibit these patterns. Along with the diagnosis comes a recommendation: we can and should understand one traditional disagreement about the metaphysics of entanglement as another manifestation of a familiar and more general conflict between reductive and non-reductive conceptions of metaphysical theorizing. Such reframing makes clearer what resources reductionists have for resisting the simple argument’s challenge from quantum holism. It also has an important moral for their opponents. Traditional focus on whole-part supervenience failure distracts from a root disagreement about metaphysical structure and its role in our theorizing. Non-reductionists fond of our simple argument would be better off tackling this root directly. (shrink)

In this work Ockham proposes a theory of simple predication, which he uses in explicating the truth conditions of progressively more complicated kinds of propositions. His discussion includes what he takes to be the correct semantic treatment of quantified propositions, past tense and future tense propositions, and modal propositions, all of which are receiving much attention from contemporary philosophers. He also illustrates the use of exponential analysis to deal with propositions that prove troublesome in both semantic theory and other disciplines, (...) such as metaphysics, physics, and theology. This type of analysis plays an essential role in his substantive philosophical and theological works, and in many cases then can hardly be understood without a prior acquaintance with this section of the Summa. An introduction by Alfred J. Freddoso clarifies and summarizes Ockham's theory, discusses certain philosophical problems which it engenders, and proposes new interpretations for parts of it. The essay will be helpful both to those interested in Ockham as a historical figure and to those interested in his substantive systematic contributions to logical theory. (shrink)

The following quotations describe in “nutshells” a few highlights of John Archibald Wheeler's contributions to physics. The contributions are arranged in roughly the following order: (i) concrete research results, (ii) innovative ideas that have become foundations for the research of others, (iii) insights that give guidance for the development of physics over the coming decades. Since most of Wheeler's work contains strong elements of two or even all three of these characteristics, the editors have not attempted to delineate (...) the dividing lines between the three categories.

It explores theoretical and practical examples of how the physically active body can be examined as a material, social, political, and cultural entity using a Deleuzian perspective. Examining topics such as, the formation of thought within a capitalist system; sport, exercise, and dance as cultural arrangements; researching the physically active body from a Deleuzian perspective; and Deleuze on Foucault, this book shows ways (...) of investigating the moving body as an agent for initiating social change. This is fascinating reading for students and researchers working in the fields of the Sociology of Sport, Sport and Politics, and Sport and Social Theory. (shrink)

Physical Education (PE) aims to convey the joy of exercise and by this educate students to lifelong physical activeness. Student motivation in PE decreases during the school career. This study therefore comprehensively analyzes student characteristics determining motivation in PE:General Personality Traits, Physical Self-Concept, Achievement Motive, Motives to be physically active, andSports Interest. This contribution aims to describe students' prerequisites in the PE context by using an aggregated assessment of the abovementioned general plus sport specific characteristics and to detect gender, class, (...) and school type differences. In total, 1,740 German secondary school students (58.1% female, M = 14.39 years) participate in a cross-sectional questionnaire survey. Descriptive analyses and between subjects MANOVAs followed by univariate ANOVAs with pairwise multiple comparison tests are applied. Gender explains the largest proportion of variance across all characteristics. Regarding individual dimensions, genders differed on 12, grades on two and school types on 11 out of 19 dimensions. PE teachers must adapt teaching to different gender dispositions. In general, group differences ascribe special meaning to student perception and teaching behavior. Findings are discussed in terms of their contribution to the research area and their implementation in teaching practice as well as in PE teacher education or professional training, e.g., aligned teaching methods, arranged learning atmospheres, or adjusted content design of PE lessons.

The quality of doctoral-level chemistry (N=145), computer science (N=58), geoscience (N=91), mathematics (N=115), physics (N=123), and statistics/biostatistics (N=64) programs at United States universities was assessed, using 16 measures. These measures focused on variables related to: program size; characteristics of graduates; reputational factors (scholarly quality of faculty, effectiveness of programs in educating research scholars/scientists, improvement in program quality during the last 5 years); university library size; research support; and publication records. Chapter I discusses prior attempts to assess quality in graduate (...) education, development of the study plans, and the selection of disciplines and programs to be evaluated. Chapter II discusses the methodology used, focusing on each of the assessment measures. Chapters III to VIII present, respectively, findings from the analyses of the chemistry, computer science, geoscience, mathematics, physics, and statistics/biostatistics programs. Chapter IX includes a summary of results, correlations among measures, several additional analyses, and suggestions for future studies. Among the findings reported are those indicating that mathematics programs had, on the average, the largest number of faculty (N=33) in December 1980 followed closely by physics (N=28) and chemistry (N=23), and that 80 percent of computer science students had job commitments by graduation.

This essay asks how we might articulate a political theory of algorithms. To do so, I propose a political ontology of the algorithm dispositif that elaborates how algorithms arrange the movement of energies in space and time, and how they do so automatically. This force of arrangement is what I refer to as the dispositional power of algorithms that I identify as a political physics of vital processes. The essay is divided into three sections. The first provides readers of (...) Political Theory with a discussion of three notable works in the field of critical algorithm studies relevant to a political theory of algorithms. The subsequent sections of the essay elaborate an understanding of the political ontology of the algorithm dispositif by focusing on the difference that a virtual ontology introduces to our political reflections and on the cybernetic operation of negative feedback that I identify as foundational to understanding an algorithm’s political physics of vital processes. I conclude that any political theory engagement with technical media can’t simply rest on an epistemic analysis of the normative effects of media but must also pursue an investigation into a medium’s modes of existence in the world.

Measurement is said to be the basis of exact sciences as the process of assigning numbers to matter (things or their attributes), thus making it possible to apply the mathematically formulated laws of nature to the empirical world. Mathematics and empiria are best accorded to each other in laboratory experiments which function as what Nancy Cartwright calls nomological machine: an arrangement generating (mathematical) regularities. On the basis of accounts of measurement errors and uncertainties, I will argue for two claims: 1) (...) Both fundamental laws of physics, corresponding to ideal nomological machine, and phenomenological laws, corresponding to material nomological machine, lie, being highly idealised relative to the empirical reality; and also laboratory measurement data do not describe properties inherent to the world independently of human understanding of it. 2) Therefore the naive, representational view of measurement and experimentation should be replaced with a more pragmatic or practice-based view.

In classical physics, the world is considered as a matter-based reality, the arrangement of whose parts in time is uniquely determined by certain dynamic laws. By contrast, modern quantum physics reveals that matter is not composed of matter, but reality is merely potentiality. The world has a holistic structure, which is based on fundamental relations and not material objects, admitting more open, indeterministic developments. In this more flexible causal framework, inanimate and animate matter are not to be considered (...) as fundamentally different but as different order structures of the same immaterial entity. In a stable configuration, effectively all the uncertainties are statistically averaged out, thus the unique and deterministic behavior of ordinary inanimate matter is exhibited; whereas in the case of statically unstable but dynamically stable configurations, the “lively” features of the underlying quantum structure have a chance to surface to the mesocopic level and to be connected with what we observe as the phenomenon of life. This supposition can be more explicitly treated and clarified by identifying the electric dipole moment of biomolecules as the ordering parameter of the corresponding macroquantum system. This has important consequences for biology and medicine. In particular, it suggests the existence of a quantum-based “software,” essential perhaps for the logistics of biological processes, which are hidden behind the matter/energy-based “hardware” that alone is considered in the conventional approach. In medicine it opens an opportunity to build bridges between conventional medicine based essentially on the classical paradigm, and the various forms of complementary medicine, which have strong affinities with the new features of the modern holistic worldview.

In lieu of an abstract, here is a brief excerpt of the content:Spinoza and the Theory of Organism HANS JONAS I CARTESIANDUALISMlanded speculation on the nature of life in an impasse: intelligible as, on principles of mechanics, the correlation of structure and function became within the res extensa, that of structure-plus-function with feeling or experience (modes of the res cogitans) was lost in the bifurcation, and thereby the fact of life itself became unintelligible at the same time that the explanation (...) of its bodily performance seemed to be assured. The impasse became manifest in Occasionalism : its tour de force of an extraneous, divine "synchronization" of the outer and the inner world (the latter denied to animals) not only suffered from its extreme artificiality, the common failing of such ad hoc constructions, but even at so high a cost failed to accomplish its theoretical purpose by its own terms. For the animal machine, like any machine, raises beyond the question of the "how" that of the "what for" of its functioning---of the purpose for which it had thus been constructed by its maker.1 Its performance, however devoid of immanent teleology, must serve an end, and that end must be someone's end. This end may (directly) be itself, as indeed Descartes had implied when declaring self-preservation to be the effect of the functioning of the organic automaton. In that case the existence as such of the machine would be its end--either terminally, or in turn to benefit something else. In the former case, the machine would have to be more than a machine, for a mere machine cannot enioy its existence. But since, by the rigorous conception of the res extensa, it cannot be more than a machine, its function and/or existence must serve something other than itself. Automata in Descartes ' time were mainly for entertainment (rather than work). But the raison d'etre of the living kingdom could not well be seen in God's indulging his mechanical abilities or in the amusement of celestial spectators--especially since mere complexity of arrangement does not create new quality and thus add something to the unrelieved sameness of the simple substratum that might enrich the spectrum of being. For quality, beyond the primitive determinations of the extended per se, is the subjective creature of sensation, the confused representation of quantity in a mind; and thus organisms cannot harbor it because as mere machines they lack mentality, and pure spirits cannot because they lack sensuality, or the privilege of confusion and thereby of illusion with its possible enjoyment. And as to their intellectual enjoyment, even that, deprived of the thrill of discovery by the same token, would pale in the contemplation of what to sufficiently large The concept of "machine," adopted for its strict confinementto efficientcause, is still a finalisticconcept,even thoughthe final cause is no longer internal to the entity, as a mode of its own operation,but external to it as antecedent design. [43] 44 HISTORY OF PHILOSOPHY intellects is nothing but the ever-repeated exemplification of the same few, elementary (and ultimately trivial) truths. There remained, then, the time-honored--Stoic as well as Christian--idea that plants and animals are for the benefit of Man. Indeed, since the existence of a living world is the necessary condition for the existence of any of its members, the self-justifying nature of at least one such member (= species) would justify the existence of the whole. In Stoicism, Man provided this end by his possession of reason, which makes him the culmination of a terrestrial scale of being that is also self-justifying throughout all its grades (the end as the best of many that are good in degrees) ; in Christianity, by his possession of an immortal soul, which makes him the sole imago Dei in creation (the end as the sole issue at stake) ; and Cartesian dualism radicalized this latter position by making man even the sole possessor of inwardness or "soul" of any kind, thus the only one of whom "end" can meaningfully be predicated as he alone can entertain ends. All other life then, the product of physical necessity, can be considered his means. However, this traditional idea, in its anthropocentric vanity never a... (shrink)

Attributed to Alexander of Aphrodisias -the leading ancient commentator on Aristotle -the Quaestiones exemplify the process through which Aristotle's thought was organized and came to be interpreted as "Aristotelianism." This volume of R.W. Sharples's translation, together with his earlier translation of Quaestiones 1.1-2.15, makes the Quaestiones available in its entirety for the first time in a modern language. The Quaestiones are concerned with problems of physics and metaphysics, psychology and divine providence. Readers interested in Aristotle's psychological views will find (...) the second half of the Quaestiones particularly valuable. Ten of the problems discussed involve issues raised in Aristotle's On the Soul, including the unity of apperception and the transition from first to second actuality in the act of contemplation. An additional twelve problems relate to aspects of physical theory such as infinity, necessity, and potentiality. Quaestio 2.21 concerns divine providence and helps supplement our knowledge of Alexander's position. A study of the Quaestiones also suggests how interpretations of Aristotle were influenced by doctrines of Hellenistic philosophy. Translated first into Arabic and then into Latin, excerpts from the Quaestiones played a significant role in the transmission of ancient Greek philosophy to the medieval world. (shrink)

The development of nuclear weapons during the Manhattan Project is one of the most significant scientific events of the twentieth century. This revised and updated 3rd edition explores the challenges that faced the scientists and engineers of the Manhattan Project. It gives a clear introduction to fission weapons at the level of an upper-year undergraduate physics student by examining the details of nuclear reactions, their energy release, analytic and numerical models of the fission process, how critical masses can be (...) estimated, how fissile materials are produced, and what factors complicate bomb design. An extensive list of references and a number of exercises for self-study are included. Links are given to several freely-available spreadsheets which users can use to run many of the calculations for themselves. (shrink)

Research on human infants has begun to shed light on early-developing processes for segmenting perceptual arrays into objects. Infants appear to perceive objects by analyzing three-dimensional surface arrangements and motions. Their perception does not accord with a general tendency to maximize figural goodness or to attend to nonaccidental geometric relations in visual arrays. Object perception does accord with principles governing the motions of material bodies: Infants divide perceptual arrays into units that move as connected wholes, that move separately from (...) one another, that tend to maintain their size and shape over motion, and that tend to act upon each other only on contact. These findings suggest that o general representation of object unity and boundaries is interposed between representations of surfaces and representations of objects of familiar kinds. The processes that construct this representation may be related to processes of physical reasoning. (shrink)

After the death of Otto Neurath in 1945, Philipp Frank appeared to be the most talented organizer of the Vienna Circle in exile. From his new position at Harvard he organized many of the Unity of Science meetings and served from 1947 on as president of the Institute for the Unity of Science. It is well known that in 1929 he had organized the famous first meeting on Erkenntnislehre der exakten Wissenschaften in Prague, at which the Vienna Circle went public. (...) Frank later wrote on this:We wanted to reach a large audience. The ordinary regular philosophy meetings followed the traditional lines and would hardly have given us enough scope. By a happy coincidence I was just in 1929 arranging a meeting of the physicists and mathematicians from the German-speaking regions in Central...The German Physical Society, which was the official sponsor of this meeting, did not particularly like the idea of combining this serious meeting with such a foolish thing as philosophy.

Probably, most of the scientists had not been accustomed to thinking of philosophy and science as a coherent system of thought...After the meeting, however, our committee received a great many letters from scientists who expressed their great satisfaction that an attempt has been made toward a coherent world conception without contradictions between science and philosophy.

_Al-Isharat wal-Tanbihat_ is one of the most mature and comprehensive philosophical works by Ibn Sina. Grounded in an exploration of logic and happiness, the text illuminates the divine, the human being, and the nature of things through a wide-ranging discussion of topics. The sections of _Physics and Metaphysics_ deal with the nature of bodies and souls as well as existence, creation, and knowledge. Especially important are Ibn Sina's views of God's knowledge of particulars, which generated much controversy in medieval Islamic (...) and Christian philosophical and theological circles and provoked a strong rejection by eleventh-century philosopher al-Ghazali. This book provides the first annotated English translation of _Physics and Metaphysics_ and edits the original Arabic text on which the translation is based. It begins with a detailed analysis of the text, followed by a translation of the three classes or groups of ideas in the Physics and the four in the Metaphysics (On Existence and Its Causes, Creation Ex Nihilo and Immediate Creation, On Ends, on Their Principles, and on the Arrangement [of Existence], and Onion. _The Metaphysics_ closes with a significant discussion of the concepts of providence, good, and evil, which Ibn Sina uses to introduce a theodicy. Researchers, faculty, and students in philosophy, theology, religion, and intellectual history will find in this work a useful and necessary source for understanding Ibn Sina's philosophical thought and, more generally, the medieval Islamic and Christian study of nature, the world beyond, psychology, God, and the concept of evil.

The purpose of this article is to propose a miming interpretation of the marriage arrangements of Republic, Book v. On this reading, Plato’s marital communism is not one of his more startling eccentricities. It is, on the contrary, an ambitious but light-hearted parable or fable, designed to throw further light on the proper relations between the public and the private in human affairs.

Trainees with disabilities in health-related professions are often subjected to structural ableism in medicine: the discriminatory manifestation of lowered expectations towards people with disabilities by medical professionals. In this case study, I reflect on my experiences as the first individual with significant disabilities to be offered a postdoctoral fellowship in clinical bioethics at the National Institutes of Health. I focus on the following question: What arrangements need to be in place in order for someone with my level of disability (...) to thrive as a clinical bioethicist? By telling my story, I show how the process of accommodating trainees with disabilities often requires creative problem-solving and a considerable amount of institutional resources. I also describe the team-based method that my mentors and I developed to enable me to complete rotations on the NIH’s bioethics consultation service. If more trainees with disabilities are to succeed in clinical bioethics trainee programs, the field will have to grapple with how to develop an infrastructure for providing disability related support across training programs. This article is the beginning of a dialogue about how to build such an infrastructure. (shrink)

Linkage (or genetic) maps are graphs, which are intended to represent the linear ordering of genes on the chromosomes. They are constructed on the basis of statistical data concerning the transmission of genes. The invention of this technique in 1913 was driven by Morgan's group's adoption of a set of hypotheses concerning the physical mechanism of heredity. These hypotheses were themselves grounded in Morgan's defense of the chromosome theory of heredity, according to which chromosomes are the physical basis of genes. (...) In this paper, I analyze the 1919 debate between William Castle and Morgan's group, about the construction of genetic maps. The official issue of the debate concerns the arrangement of genes on chromosomes. However, the disputants tend to carry out the discussions about how one should model the data in order to draw predictions concerning the transmission of genes; the debate does not bear on the data themselves, nor does it focus on the hypotheses explaining these data. The main criteria that are appealed to by the protagonists are simplicity and predictive efficacy. However, I show that both parties' assessments of the simplicity and predictive efficacy of different ways of modeling the data themselves depend on background theoretical positions. I aim at clarifying how preference for a given model and theoretical commitments articulate. (shrink)
