The vacuum structure for the massive charged scalar field in the region of two parallel, infinitely long and thin solenoids confining the fluxesn 1 andn 2 is studied. By using the Green function method, it is found that the vacuum expectation value of the system's energy has a finite mutual interaction term depending on the distance a between the solenoids, which implies an attractive force per unit length given by F n1n2 =−(ℏc/π2)(n 1 n 2)2/a 3.

This article is a translation into english of a lecture given by paneth in 1931. The content of the work is described by the section titles: (1) the need for epistemological clarification of the fundamental concepts of chemistry, (2) the concept of substance in chemistry, (3) the epistemological standpoint of the ancient atomists, (4) the epistemological position of the concept of element introduced by lavoisier, (5) the double meaning of the chemical concept of element: 'basic substance' and 'simple substance', And (...) (6) the double meaning of other chemical concepts. Sections (4)-(6) are published in the following number of this journal. (staff). (shrink)

Recently several philosophers have argued that environmental reform movements cannot halt humankind’s destruction of the biosphere because they still operate within the anthropocentric humanism that forms the root of the ecological crisis. According to “radical” environmentalists, disaster can be averted only if we adopt a nonanthropocentric understanding of reality that teaches us to live harmoniouslyon the Earth. Martin Heidegger agrees that humanism leads human beings beyond their proper limits while forcing other beings beyond their limits as weIl. The doctrine of (...) the “rights of man” justifies human exploitation of nonhuman beings. Paradoxically, however, the doctrine of rights for nonhuman beings does not escape the orbit of humanism. According to Heidegger, a nonanthropocentric conception of humanity and its relation to nature must go beyond the doctrine of rights. We can dweIl harmoniously on Earth only by submitting to our primary obligation: to be open for the Being of beings. We need a new way of understanding Being, a new ethos, that lets beings manifest themselves not merely as objects for human ends, but as intrinsically important. Heidegger calls this ethos the “fourfold” of earth and sky, gods and mortals. Humanists argue that Heidegger is wrong to abandon the principle of human rights in favor of the notion that we are obligated to “let beings be,” while some radical environmentalists accuse hirn of being a humanist because he supposedly overestimates the importance of humankind’s ability to speak. Heidegger insists, however, that language makes possible culture, without which thereis no human experience of nature. An environmentally sound ethos. can arise, according to Heidegger, only from a shift within the cultural heritage of the West. Richard Rorty agrees that we must become open for a new “conversation” with the West, even if this requires abandoning traditionally important fields such as epistemology. The need to develop a new understanding of Being is so great that thinkers from the analytic and continental traditions of philosophy are finally initiating a long-overdue dialogue. (shrink)

Foundations and Applications depend ultimately for their existence on each other. The main links between them are education and the axiomatic method. Those links can be strengthened with the help of a categorical method which was concentrated forty years ago by Cartier, Grothendieck, Isbell, Kan, and Yoneda. I extended that method to extract some essential features of the category of categories in 1965, and I apply it here in section 3 to sketch a similar foundation within the smooth categories which (...) provide the setting for the mathematics of change. The possibility that other methods may be needed to clarify a contradiction introduced by Cantor, now embedded in mathematical practice, is discussed in section 5. (shrink)

Autobiography and Teacher Development in China investigates the roles of autobiography in teacher education, as several scholars in China recontextualize Western conceptions of teacher development, combining them with uniquely Chinese cultural conceptions to articulate a reconceptualization of teacher development that holds worldwide significance. Framed by the work of Zhang Hua and William F. Pinar, these theoretical and practical essays point to an internationally inflected reconceptualization of teachers' professional development, pre-service and in-service. This volume addresses multiple movements of teacher education reform (...) worldwide, focused on crafting a nationally distinctive course not only internationally, but also culturally, historically, and locally.

Written in 1839 and chosen as the winning entry in a competition held by the Royal Norwegian Society of Sciences, Schopenhauer's Prize Essay on the Freedom of the Will marked the beginning of its author's public recognition and is widely regarded as one of the most brilliant and elegant treatments of free will and determinism. Schopenhauer distinguishes the freedom of acting from the freedom of willing, affirming the former while denying the latter. He portrays human action as thoroughly determined but (...) also argues that the freedom which cannot be established in the sphere of human action is preserved at the level of our innermost being as individuated will, whose reality transcends all dependency on outside factors. This volume offers the text in a previously unpublished translation by Eric F. J. Payne, the leading twentieth-century translator of Schopenhauer into English, together with a historical and philosophical introduction by Günter Zöller. (shrink)

We no longer have any texts, any past, but just interpretations of them. The evident multi -interpretability of a text causes it gradually to lose its capacity to function as arbiter in the historical debate. It is necessary to define a new link with the past based on a complete and honest recognition of the position in which we now see ourselves placed as historians. In recent years, many people have observed our changed attitude towards the phenomenon of information. For (...) postmodernism, science and information are independent objects of study which obey their own laws. Language and art are not situated opposite reality but are themselves a pseudo-reality and are therefore situated within reality. Because of the relation between the historiographical view and the language used by the historian to express his view - a relation which nowhere intersects the domain of the past -historiography possesses the same opacity and intensional dimension as art. The essence of postmodernism is precisely that we should avoid pointing out essentialist patterns in the past. There is reason to assume that our relation to the past and our insight into it will in future be of a metaphorical nature rather than a literal one. (shrink)

This is a transcript of a conversation between P F Strawson and Gareth Evans in 1973, filmed for The Open University. Under the title 'Truth', Strawson and Evans discuss the question as to whether the distinction between genuinely fact-stating uses of language and other uses can be grounded on a theory of truth, especially a 'thin' notion of truth in the tradition of F P Ramsey.

In Practicing Safe Sects F. LeRon Shults provides scientific and philosophical resources for having “the talk” about religious reproduction: where do gods come from – and what are the costs of bearing them in our culturally pluralistic, ecologically fragile environment?

RésuméL'intention est de présenter ľidée de complémentarité de façon à la fois générale et élémentaire, convenant à la fois en physique et dans ?autres domaines. Le progrés se fait par dévoilement ?horizons de réalité successifs, dont trois sont envisageés ici: ľhorizon naturel , ľhorizon classique, ľhorizon quantique.L'idée de complémentarité se présente assez élémentairement dans le raccordement de deux horizons, dont ľun joue le rô1e ?horizon apparent et ľautre ?horizon profond.Le cadre obligé de considérations de ce genre est une méthodologie dialectique (...) ouverte. Dans ce cadre, ľidée de la complémentarité onde‐corpuscule apparaît comme une spécialisation ?un schéma plus géneral. F. G.ZnsammenfassungDie Idee der Komplementarität soll zugleich generell und elementar, auf eine für die moderne Physik und für andere Gebiete passende Art, dargelegt werden.Der Fortschritt der Erkenntnis führt zu der Konstituierung von aufeinander folgenden Wirklichkeitshorizonten. Es werden hier drei solche Horizonte besprochen : der natürliche Horizont , der klassische und der quantische Horizont.Die Idee der Komplementarität spielt eine Hauptrolle in der Beziehung zweier Wirklichkeitshorizonten zueinander, eines phänomenalen und eines tieferen Horizonts.Der notwendige erkenntnistheoretische Rahmen für derartige Betrachtungen ist eine dialektiseh‐offene Methodologie . In diesen Rahmen erscheint die übliche Komplementarität als eine Speziali‐sierung eines allgemeineren Schemas. (shrink)

This is the first comprehensive translation of the expanded French version of E.F.F. Chladni's Traité d'Acoustique, using Chladni's 1802 Die Akustik for reference and clarification. Chladni's experiments and observations with sound and vibrations profoundly influenced the development of the field of Acoustics. The famous Chladni diagrams along with other observations are contained in Die Akustik, published in German in 1802 and Traité d'Acoustique, a greatly expanded version, published in French in 1809. The present translation was undertaken by Robert T. Beyer, (...) PhD (1920-2008), noted acoustician, Professor of Physics at Brown University, and Gold Medal recipient of the Acoustical Society of America. Along with many other projects completed over the course of his career, Dr. Beyer translated Von Neumann's seminal work, Mathematical Foundations of Quantum Mechanics from the original German, spent 30 years translating Russian physics treatises and journals, served as editor of the English translation of the Soviet Journal of Experimental and Theoretical Physics, and also authored Sounds of our Times: Two Hundred Years of Acoustics. Represents the first comprehensive English translation of a seminal work in acoustics Translated by a prominent acoustician, and former Gold Medal recipient of the Acoustical Society of America In addition to the classic experiments with glass plates and violin bows, covers topics in music, architecture, and anatomy of human and animal hearing Appeals to a wide audience in physics, acoustics, and history of science.

My discussion addresses the differences between analytic and continental philosophy concerning the use of logic and exact reasoning in philosophical practice. These differences are mainly examined in the light of the controversial dominance of Hegel's concept of logic (and theory of concept) in twentieth-century continental philosophy. The inquiry is developed in two parts. In the first (Sections 1-2), I indicate some aspects of the analytic-continental divide, pointing to the role that the topic 'logic and philosophy' plays in it. In the (...) second part (Sections 3-6), I give a short account of the views of logic which are typical of the three main trends of continental philosophy (see Table 1). I also suggest how, with the aid of some typical analytical devices, some continental 'anti-logical' attitudes may be corrected, on their own terms. (shrink)
