Deductive science (e.g. relativity or thermodynamics) has a fundamental property: any anomalous result suggests that either an axiom is false or an argument is invalid. Therefore, instead of proclaiming experimental verification as the only sanitary procedure in theoretical science, a procedure that unavoidably creates camouflage in the end, philosophers of science should have coined the simple slogan: "Anomaly? Identify the false axiom or the invalid argument!" Nowadays clever philosophers implicitly reject the experimental falsification but, in conformity with the "ethics" of Postscientism, can only offer vague or misleading (insofar as looking for a false axiom or an invalid argument is concerned) hints instead: http://philsci-archive.pitt.edu/archive/00000313/ Jos Uffink: "What is it that makes this physical law so obstreperous that every attempt at a clear formulation seems to have failed? Is it just the usual sloppiness of physicists? Or is there a deeper problem? And what exactly is the connection with the arrow of time and irreversibility? Could it be that this is also just based on bluff? Perhaps readers will shrug their shoulders over these questions. Thermodynamics is obsolete; for a better understanding of the problem we should turn to more recent, statistical theories. But even then the questions we are about to study have more than a purely historical importance. The problem of reproducing the Second Law, perhaps in an adapted version, remains one of the toughest, and controversial problems in statistical physics. (...) This summary leads to the question whether it is fruitful to see irreversibility or time- asymmetry as the essence of the second law. Is it not more straightforward, in view of the unargued statements of Kelvin, the bold claims of Clausius and the strained attempts of Planck, to give up this idea? I believe that Ehrenfest-Afanassjewa was right in her verdict that the discussion about the arrow of time as expressed in the second law of the thermodynamics is actually a RED HERRING." http://www.amazon.com/Relativity-Simultaneity-Routledge-Contemporary-Philosophy/dp/0415701740 Einstein, Relativity and Absolute Simultaneity (Routledge Studies in Contemporary Philosophy) "Einstein, Relativity and Absolute Simultaneity is an anthology of original essays by an international team of leading philosophers and physicists who, on the centenary of Albert Einsteins Special Theory of Relativity, come together in this volume to reassess the contemporary paradigm of the relativistic concept of time. A great deal has changed since 1905 when Einstein proposed his Special Theory of Relativity, and this book offers a fresh reassessment of Special Relativitys relativistic concept of time in terms of epistemology, metaphysics and physics. There is no other book like this available; hence philosophers and scientists across the world will welcome its publication." "UNFORTUNATELY FOR EINSTEIN'S SPECIAL RELATIVITY, HOWEVER, ITS EPISTEMOLOGICAL AND ONTOLOGICAL ASSUMPTIONS ARE NOW SEEN TO BE QUESTIONABLE, UNJUSTIFIED, FALSE, PERHAPS EVEN ILLOGICAL." Craig Callender: "In my opinion, by far the best way for the tenser to respond to Putnam et al is to adopt the Lorentz 1915 interpretation of time dilation and Fitzgerald contraction. Lorentz attributed these effects (and hence the famous null results regarding an aether) to the Lorentz invariance of the dynamical laws governing matter and radiation, not to spacetime structure. On this view, Lorentz invariance is not a spacetime symmetry but a dynamical symmetry, and the special relativistic effects of dilation and contraction are not purely kinematical. The background spacetime is Newtonian or neo- Newtonian, not Minkowskian. Both Newtonian and neo-Newtonian spacetime include a global absolute simultaneity among their invariant structures (with Newtonian spacetime singling out one of neo-Newtonian spacetimes many preferred inertial frames as the rest frame). On this picture, there is no relativity of simultaneity and spacetime is uniquely decomposable into space and time." http://www.pitt.edu/~jdnorton/Goodies/passage/index.html John Norton, 1 Mar 2009: "A common belief among philosophers of physics is that the passage of time of ordinary experience is merely an illusion. The idea is seductive since it explains away the awkward fact that our best physical theories of space and time have yet to capture this passage. I urge that we should resist the idea. We know what illusions are like and how to detect them. Passage exhibits no sign of being an illusion....Following from the work of Einstein, Minkowski and many more, physics has given a wonderfully powerful conception of space and time. Relativity theory, in its most perspicacious form, melds space and time together to form a four- dimensional spacetime. The study of motion in space and and all other processes that unfold in them merely reduce to the study of an odd sort of geometry that prevails in spacetime. In many ways, time turns out to be just like space. In this spacetime geometry, there are differences between space and time. But a difference that somehow captures the passage of time is not to be found. There is no passage of time. There are temporal orderings. We can identify earlier and later stages of temporal processes and everything in between. What we cannot find is a passing of those stages that recapitulates the presentation of the successive moments to our consciousness, all centered on the one preferred moment of "now." At first, that seems like an extraordinary lacuna. It is, it would seem, a failure of our best physical theories of time to capture one of time's most important properties. However the longer one works with the physics, the less worrisome it becomes....I was, I confess, a happy and contented believer that passage is an illusion. It did bother me a little that we seemed to have no idea of just how the news of the moments of time gets to be rationed to consciousness in such rigid doses.....Now consider the passage of time. Is there a comparable reason in the known physics of space and time to dismiss it as an illusion? I know of none. The only stimulus is a negative one. We don't find passage in our present theories and we would like to preserve the vanity that our physical theories of time have captured all the important facts of time. So we protect our vanity by the stratagem of dismissing passage as an illusion." Pentcho Valev wrote: Karl Popper's ethical problems: http://www.informaworld.com/smpp/content~content=a909857880 Peter Hayes: "Popper obscures but does not altogether hide the extraordinary implications of his tentative suggestion that Lorentz and Newton may not have been superseded after all. We see a kind of internal duel in which Popper the falsificationist scientist wrestles with Popper the ideological defender of Einstein. The result is a messy draw in which, through what can only be called a series of unsatisfactory auxiliary hypotheses, Popper attempts to retain the idea that Einstein's relativity theory represents some form of scientific advance even in if absolute space and time remain intact. Thus, Einsteins other achievements are emphasised and the difference between Einstein and Lorentz is minimised (Popper 1982, 29, 35, 48, 158). Finally, the very concept of scientific advance is adapted to fit the new circumstances: Karl Popper: "The decisive thing about Einstein's theory, from my point of view, is that it has shown that Newton's theory - which has been more successful than any other theory ever proposed - can be replaced by an alternative theory which is of wider scope, and which is so related to Newton's theory that every success of Newtonian theory is also a success for that theory, and which in fact makes slight adjustments to some results of Newtonian theory. So for me, this logical situation is more important than the question which of the two theories is in fact the better approximation to the truth" (Popper 1982, 2930)." Pentcho Valev pvalev@yahoo.com
