This concise book introduces nonphysicists to the core philosophical issues surrounding the nature and structure of space and time, and is also an ideal resource for physicists interested in the conceptual foundations of space-time theory. Tim Maudlin's broad historical overview examines Aristotelian and Newtonian accounts of space and time, and traces how Galileo's conceptions of relativity and space-time led to Einstein's special and general theories of relativity. Maudlin explains special relativity using a geometrical approach, emphasizing intrinsic space-time structure rather than (...) coordinate systems or reference frames. He gives readers enough detail about special relativity to solve concrete physical problems while presenting general relativity in a more qualitative way, with an informative discussion of the geometrization of gravity, the bending of light, and black holes. Additional topics include the Twins Paradox, the physical aspects of the Lorentz-FitzGerald contraction, the constancy of the speed of light, time travel, the direction of time, and more.Introduces nonphysicists to the philosophical foundations of space-time theory Provides a broad historical overview, from Aristotle to Einstein Explains special relativity geometrically, emphasizing the intrinsic structure of space-time Covers the Twins Paradox, Galilean relativity, time travel, and more Requires only basic algebra and no formal knowledge of physics.

In 1996 physicist Alan Sokal published an essay in Social Text--an influential academic journal of cultural studies--touting the deep similarities between quantum gravitational theory and postmodern philosophy. Soon thereafter, the essay was revealed as a brilliant parody, a catalog of nonsense written in the cutting-edge but impenetrable lingo of postmodern theorists. The event sparked a furious debate in academic circles and made the headlines of newspapers in the U.S. and abroad. Now in Fashionable Nonsense: Postmodern Intellectuals' Abuse of Science, Sokal (...) and his fellow physicist Jean Bricmont expand from where the hoax left off. In a delightfully witty and clear voice, the two thoughtfully and thoroughly dismantle the pseudo-scientific writings of some of the most fashionable French and American intellectuals. More generally, they challenge the widespread notion that scientific theories are mere "narrations" or social constructions. (shrink)

Si Meyerson, immigrant polonais, ne peut pas s’intégrer dans un cadre institutionnel académique, il sait s’imposer dans les milieux intellectuels français grâce à l’écho que connaît son premier ouvrage qui lui en ouvre la porte d’accès. Sa soif de reconnaissance l’incite à solliciter l’avis des personnalités du monde scientifique et philosophique et à créer ainsi des liens où il sait s’imposer. Son autorité est incontestable auprès des jeunes, même si certains s’en détachent.If Meyerson, an immigrated Polish, could not be integrated (...) in an academic institutional framework, he had succeeded in becoming essential to the French intellectual milieus thanks to the echo which his first book has received which has opened him the gates to it. His thirst for recognition has encouraged him to ask for the opinion of the personalities of the scientific and philosophical world and to thus create links where he could impose himself. His authority is undeniable to the young people, even if some have left him. (shrink)

The 1919 eclipse expedition’s confirmation of general relativity is often celebrated as a triumph of scientific internationalism. However, British scientific opinion during World War I leaned toward the permanent severance of intellectual ties with Germany. That the expedition came to be remembered as a progressive moment of internationalism was largely the result of the efforts of A. S. Eddington. A devout Quaker, Eddington imported into the scientific community the strategies being used by his coreligionists in the national dialogue: humanize the (...) enemy through personal contact and dramatic projects that highlight the value of peace and cooperation. The essay also addresses the common misconception that Eddington’s sympathy for Einstein led him intentionally to misinterpret the expedition’s results. The evidence gives no reason to think that Eddington or his coworkers were anything but rigorous. Eddington’s pacifism is reflected not in manipulated data but in the meaning of the expedition and the way it entered the collective memory as a celebration of international cooperation in the wake of war. Science is above all politics. —Sir Oliver Lodge (1914) Is it not an actual fact that babies have been killed in ways almost inconceivably brutal, and not as a mere individual excess, but as a part of the deliberate and declared policy of the German army? … Is it not a fact that German men of science have gone out of their way to declare their adhesion to these things? —“From an Oxford Note‐Book,” Observatory (1916).

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 36.1 (2003) 1-21 [Access article in PDF] Did Habermas Cede Nature to the Positivists? Gordon R. Mitchell Jürgen Habermas's "colonization of the lifeworld" thesis (1987, 332-73) posits that many of society's pathologies are due to the tendency of institutions to convert social issues that ought to be sorted out by a debating citizenry into technical problems ripe for resolution by expert bureaucracies, thus pre-empting important public (...) discussion. Habermas has attempted to lay bare the pernicious effects of this colonization process in his analysis of public opinion polling, welfare policy, education, German reunification, immigration, and other social issues (see Habermas 1997, 1994, and 1970; Holub 1992). In each of these contexts, Habermas has publicly challenged the encroachment of scientistic modes of decision-making into spheres where joint communicative action by deliberating citizens would yield more appropriate and legitimate judgments. This critical impulse is also evident in Habermas's methodological reflections on the proper role of academic scholarship, where he has argued vigorously against attempts to graft "objectivating" methods of natural scientific inquiry onto research projects in the social sciences (1971, 304-17).From all of this, one might gather that Habermas's commitment to rolling back the influence of technical forms of reasoning is connected to some intrinsic quarrel he has with the natural sciences. Yet such a sweeping generalization is hard to sustain in light of the fact that Habermas does not oppose technical reasoning per se; he recognizes that the daunting complexity of social life in late capitalism requiresthat certain "steering" tasks be delegated to systems that utilize largely instrumental logics to co-ordinate action. Likewise, he acknowledges that the disciplines of the natural sciences necessarily play important supporting roles in such steering projects.One normative presupposition of Habermas's colonization thesis is that there exists some proper boundary demarcating where the sphere of technical reasoning ends and the realm of communicative rationality begins. [End Page 1] On one side of this boundary, Habermas has provided many details on what he sees as the essential qualities of a properly functioning "public sphere," where "new social movements" continuously reweave the threads of communicative fabric holding society together (1996, 359-87), and where "historico-hermeneutic" academic study reflects on public life, sluicing insight back into the capillaries of democratic deliberations (1987, 374-403).What lies on the other side of the boundary is murkier. The proper role of natural scientific investigation has received relatively scant attention in Habermas's critical theory of society, and this has led to some confusion regarding his account of the natural sciences, as well as debate over whether this account has political purchase. One would think that sympathetic commentators, such as Helen Longino (who bases much of her own coherence theory of scientific truth on Habermas), would have reassuring things to say on this point. Yet her lukewarm assessment that, "in trying to clear a space for an autonomous social and critical theory, [Habermas] has ceded nature to the positivists" (1990, 202), raises questions about the flexibility and scope of Habermas's theory of communicative action as a basis for critique of scientific practice.One way to test Habermas's account of the natural sciences on this count is to put his views in conversation with science studies commentators who share a similar commitment to the idea that dialogue and argumentation are constitutive elements of scientific practice. Such an approach recasts the "ceding to positivism" question into a moment of controversy over the role of dialogue, not only as an essential motor driving the scientific enterprise, but also as a vehicle for democratic decision-making on issues related to the purpose and direction of scientific inquiry in society.Part one of this essay locates discursive norms embedded pragmatically in the notion of scientific objectivity. By bringing a modified version of Habermas's theory of communicative action into conversation with other approaches to science studies that foreground intersubjective dialogue as the key motor driving the scientific enterprise, I develop a foundation for robust criticism of systematically distorted scientific communication. Specific strategies of... (shrink)

This is an important book precisely because there is none other quite like it.

Au printemps 1996, une revue américaine fort respectée - Social Text - publiait un article au titre étrange : "Transgresser les frontières : vers une herméneutique transformative de la gravitation quantique". Son auteur, Alan Sokal, étayait ses divagations par des citations d'intellectuels célèbres, français et américains. Peu après, il révélait qu'il s'agissait d'une parodie. Son but était de s'attaquer, par la satire, à l'usage intempestif de terminologie scientifique et aux extrapolations abusives des sciences exactes aux sciences humaines. Plus généralement, il (...) voulait dénoncer le relativisme postmoderne pour lequel l'objectivité est une simple convention sociale. Ce canular a déclenché un vif débat dans les milieux intellectuels, en France et à l'étranger. Dans ce livre, les auteurs ont rassemblé et commenté des textes illustrant les mystifications physico-mathématiques de Jacques Lacan, Julia Kristeva, Luce Irigaray, Bruno Latour, Jean Baudrillard, Gilles Deleuze, Félix Guattari et Paul Virilio, auteurs qui jouissent tous d'une grande notoriété aux Etats-Unis. Ils montrent que, derrière un jargon imposant et une érudition scientifique apparente, le roi est nu. Après les vives polémiques suscitées par la version initiale d'Impostures intellectuelles, cette nouvelle édition, revue et enrichie d'une préface inédite (1999), procure aux auteurs l'occasion d'une nécessaire mise au point. Ils y précisent leur point de vue. Ils écartent les idées voire les arrière-pensées qui leur ont été à tort attribuées. (shrink)

How are fundamental constants, such as c for the speed of light, related to particular technological environments? Our understanding of the constant c and Einstein’s relativistic cosmology depended on key experiences and lessons learned in connection to new forms of telecommunications, first used by the military and later adapted for commercial purposes. Many of Einstein’s contemporaries understood his theory of relativity by reference to telecommunications, some referring to it as “signal-theory” and “message theory.” Prominent physicists who contributed to it (Hans (...) Reichenbach, Max Born, Paul Langevin, Louis de Broglie, and Léon Brillouin, among others) worked in radio units during WWI. At the time of its development, the old Newtonian mechanics was retrospectively rebranded as based on the belief in a means of “instantaneous signaling at a distance.” Even our thinking about lengths and solid bodies, argued Einstein and his interlocutors, needed to be overhauled in light of a new understanding of signaling possibilities. Pulling a rod from one side will not make the other end move at once, since relativity had shown that “this would be a signal that moves with infinite speed.” Einstein’s universe, where time and space dilated, where the shortest path between two points was often curved and which broke the laws of Euclidean geometry, functioned according to the rules of electromagnetic signal transmission. For some critics, the new understanding of the speed of light as an unsurpassable velocity—a fundamental tenet of Einstein’s theory—was a mere technological effect related to current limitations in communication technologies.
