This high-level study discusses Newtonian principles and 19th-century views on electrodynamics and the aether. Additional topics include Einstein's electrodynamics of moving bodies, Minkowski spacetime, gravitational geometry, time and causality, and other subjects. Highlights include a rich exposition of the elements of the special and general theories of relativity.
A magisterial study of the philosophy of physics that both introduces the subject to the non-specialist and contains many original and important contributions for professionals in the area. Modern physics was born as a part of philosophy and has retained to this day a properly philosophical concern for the clarity and coherence of ideas. Any introduction to the philosophy of physics must therefore focus on the conceptual development of physics itself. This book pursues that development from Galileo and Newton through (...) Maxwell and Boltzmann to Einstein and the founders of quantum mechanics. There is also discussion of important philosophers of physics in the eighteenth and nineteenth centuries and of twentieth-century debates. In the interest of appealing to the broadest possible readership the author avoids technicalities and explains both the physics and philosophical terms. (shrink)
This book, explores the conceptual foundations of Einstein's theory of relativity: the fascinating, yet tangled, web of philosophical, mathematical, and physical ideas that is the source of the theory's enduring philosophical interest. Originally published in 1986. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These paperback editions preserve the original texts of these important books while presenting them in durable paperback editions. The goal of (...) the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

"A pleasure to read. Gracefully written by a scholar well grounded in the relevant philosophical, historical, and technical background. . . . a helpfully clarifying review and analysis of some issues of importance to recent philosophy of science and a source of some illuminating insights."--Burke Townsend, Philosophy of Science.

Responding to Hasok Chang’s vision of the history and philosophy of science as the continuation of science by other means, I illustrate the methods of HPS and their utility through a historico-critical examination of the problem of “time’s arrow‘, that is to say, the problem posed by the claim by Boltzmann and others that the temporal asymmetry of many physical processes and indeed the very possibility of identifying each of the two directions we distinguish in time must have a ground (...) in the laws of nature. I claim that this problem has proved intractable chiefly because the standard mathematical representation of time employed in the formulation of the laws of nature “forgets‘ one of the connotations of the word ”time’ as it is used in ordinary language and in experimental physics.

The subject of this paper is objectivity from Kant's point of view: or better, my own perspective on Kant's perspective on objectivity. More precisely, I want to draw attention to some aspects of the latter, which I believe are too narrow and must be widened before we can benefit from a Kantian approach today.
In this paper I take a sceptical view of the standard cosmological model and its variants, mainly on the following grounds: (i) The method of mathematical modelling that characterises modern natural philosophy-as opposed to Aristotle's-goes well with the analytic, piecemeal approach to physical phenomena adopted by Galileo, Newton and their followers, but it is hardly suited for application to the whole world. (ii) Einstein's first cosmological model (1917) was not prompted by the intimations of experience but by a desire to (...) satisfy Mach's Principle. (iii) The standard cosmological model-a Friedmann-Lematre-Robertson-Walker spacetime expanding with or without end from an initial singularity-is supported by the phenomena of redshifted light from distant sources and very nearly isotropic thermal background radiation provided that two mutually inconsistent physical theories are jointly brought to bear on these phenomena, viz the quantum theory of elementary particles and Einstein's theory of gravity. (iv) While the former is certainly corroborated by high-energy experiments conducted under conditions allegedly similar to those prevailing in the early world, precise tests of the latter involve applications of the Schwarzschild solution or the PPN formalism for which there is no room in a Friedmann-Lematre-Robertson-Walker spacetime.

Se explican dos ideas capitales de la epistemología de Bachelard y su relación mutua: la ciencia es fenomenotécnica, la ciencia inventa sus conceptos La producción de fenómenos con arreglo a esos conceptos certifica su idoneidad.We explain two main ideas of Bachelard’s philosophy of science and their mutual relation. Science produces phenomena and creates its own concepts. Production of phenomena according to these concepts certifies their aptness.
Debido a la historicidad de la razón, más que inventariar sus principales conceptos en un momento dado nos interesa estudiar el proceso de su formación y fijación. En este artículo se ilustra ese proceso con ejemplos tomados de la historia de la física. El primer ejemplo concierne a la subordinación en el siglo XVII de los fenómenos archiconocidos de la caída libre y el movimiento de los planetas a un concepto nuevo; los restantes, tomados de la electrodinámica del siglo XIX (...) y la microfísica y la cosmología del siglo XX, ilustran el juego mutuo de tales conceptos con novedades empíricas que en algunos casos los provocan, en otros los realizan.

RESUMEN: La biología evolucionista no ha logrado definir un concepto de especie que satisfaga a todos sus colaboradores. El presente panorama crítico de las principales propuestas y sus respectivas dificultades apunta, por un lado, a ilustrar los procesos de formación de conceptos en las ciencias empíricas y, por otro, a socavar la visión parateológica del conocimiento y la verdad que inspiró inicialmente a la ciencia moderna y prevalece aún entre muchas personas educadas. El artículo se divide en dos partes. La (...) primera atiende al concepto biológico (o genético) de especie adoptado por Theodosius Dobzhansky y Ernst Mayr alrededor de 1940, así como a las alternativas introducidas para superar sus limitaciones. La segunda parte estudia la tradición “cladista” fundada por Willi Hennig (1950) y sus ramificaciones. Varios conceptos de especie que no era fácil integrar en estos dos grupos se omitieron en aras de la coherencia y la brevedad de la exposición.ABSTRACT: Evolutionary biology has not suceeded in defining a concept of species that will satisfy all researchers. This critical survey of the main proposals and their respective difficulties tends, on the one hand, to throw light on the processes of concept formation in the empirical sciences, and, on the other, to undermine the paratheological vision of knowledge and truth that initially inspired modern science and still prevails among many educated persons. The article is divided into two parts. The first part concerns the biological (or genetical) concept of species which was adopted by Theodosius Dobzhansky and Ernst Mayr ca. 1940 and some alternatives which were subsequently introduced to overcome its limitations. The second part deals with several branches of the cladist tradition founded by Willi Hennig (1950). Various concepts of species that could not be easily integrated in either group were omitted for the sake of coherence and brevity. (shrink)
Informe sobre The Cambridge Companion to the Philosophy of Biology, David L. Hull y Michael Ruse, eds. y Philosophy of Biology, Mohan Matthen y Christopher Stephens, eds.. A review essay concerning The Cambridge Companion to the Philosophy of Biology, David L. Hull and Michael Ruse, eds. and Philosophy of Biology, Mohan Matthen and Christopher Stephens, eds.
La publicación de un segundo Cambridge Companion to Kant, catorce años después del primero, con el propósito, no de sustituirlo, sino de completarlo, confirma el continuo y creciente interés por la filosofía de Kant en los países de lengua inglesa, manifiesto ya en la monumental empresa de traducir a ese idioma sus obras completas.
