The principle "ANYTHING can be deduced from ANYTHING" was introduced by Clausius in 1850. Consider the following arguments: (A) If it rains, then the soil is wet. (B) If Peter and Paul are identical twins, then Peter looks like Paul. (C) (Sadi Carnot 1824) If heat is an indestructible substance (cannot be converted into work in the heat engine), then Heat Engine 1 working between the temperatures T1 and T2 is just as efficient as Heat Engine 2 working between the same temperatures. The prior (that is, before the premise is taken into account) probability of A's conclusion is not zero so the combination "false premise, true conclusion" is possible. In contrast, the prior probability of B's and C's conclusions is virtually zero so the combination "false premise, true conclusion" is virtually impossible. Yet C's conclusion (the prototype of the second law of thermodynamics), although deduced from a false premise and therefore false as well, was crucially important for Clausius' and Kelvin's careers so in 1850 Clausius advanced the following INVALID argument: (C') (Clausius 1850) If heat always flows spontaneously from hot to cold, then Heat Engine 1 working between the temperatures T1 and T2 is just as efficient as Heat Engine 2 working between the same temperatures. Clausius' 1850 "deduction" had the effect of opening a Pandora box so half a century later the scientific community was ready to accept the conclusions of the following arguments: (D) (Albert Einstein) If the speed of light does not depend on the speed of the light source, then a situation is possible in which I observe your clock running slower than mine and you observe mine running slower than yours and both observations are correct. (E) (Albert Einstein) If the speed of light does not depend on the speed of the light source, then an 80m long pole can safely be trapped inside a 40m long barn.

Silly Walks Director: "Mr Pudey, the very real problem is one of money. I'm afraid that the Ministry of Silly Walks is no longer getting the kind of support it needs. You see there's Defence, Social Security, Health, Housing, Education, Silly Walks ... they're all supposed to get the same. But last year, the Government spent less on the Ministry of Silly Walks than it did on National Defence! Now we get 348,000,000 a year, which is supposed to be spent on all our available products." L. McGlashan, Chemical thermodynamics, Academic Press, London (1979), pp. 72-73: "For an infinitesimal change in the state of a phase alpha we write dU = T dS - p dV + SUM mu_B dn_B (1) We regard equation (1) as an axiom and call it the fundamental equation for a change of the state of a phase alpha. It is one half of the second law of thermodynamics. We do not ask where it comes from. Indeed we do not admit the existence of any more fundamental relations from which it might have been derived. Nor shall we here enquire into the history of its formulation, though that is a subject of great interest to the historian of science. It is a starting point ; it must be learnt by heart." http://philsci-archive.pitt.edu/archive/00000313/ "A more important objection, it seems to me, is that Clausius bases his conclusion that the entropy increases in a nicht umkehrbar [irreversible] process on the assumption that such a process can be closed by an umkehrbar [reversible] process to become a cycle. This is essential for the definition of the entropy difference between the initial and final states. But the assumption is far from obvious for a system more complex than an ideal gas, or for states far from equilibrium, or for processes other than the simple exchange of heat and work. Thus, the generalisation to all transformations occurring in Nature is somewhat rash." http://o.castera.free.fr/pdf/Chronogeometrie.pdf Jean-Marc Lévy-Leblond "De la relativité à la chronogéométrie ou: Pour en finir avec le "second postulat" et autres fossiles": "D'autre part, nous savons aujourd'hui que l'invariance de la vitesse de la lumière est une conséquence de la nullité de la masse du photon. Mais, empiriquement, cette masse, aussi faible soit son actuelle borne supérieure expérimentale, ne peut et ne pourra jamais être considérée avec certitude comme rigoureusement nulle. Il se pourrait même que de futures mesures mettent enévidence une masse infime, mais non-nulle, du photon ; la lumière alors n'irait plus à la "vitesse de la lumière", ou, plus précisément, la vitesse de la lumière, désormais variable, ne s'identifierait plus à la vitesse limite invariante. Les procédures opérationnelles mises en jeu par le "second postulat" deviendraient caduques ipso facto. La théorie elle-même en serait-elle invalidée ? Heureusement, il nen est rien ; mais, pour sen assurer, il convient de la refonder sur des bases plus solides, et dailleurs plus économiques. En vérité, le premier postulat suffit, à la condition de lexploiter à fond." http://www.hep.princeton.edu/~mcdonald/examples/mechanics/levy-leblond_ajp_44_271_76.pdf Jean-Marc Levy-Leblond: "This is the point of view from wich I intend to criticize the overemphasized role of the speed of light in the foundations of the special relativity, and to propose an approach to these foundations that dispenses with the hypothesis of the invariance of c. (...) We believe that special relativity at the present time stands as a universal theory discribing the structure of a common space-time arena in which all fundamental processes take place. (...) The evidence of the nonzero mass of the photon would not, as such, shake in any way the validity of the special relalivity. It would, however, nullify all its derivations which are based on the invariance of the photon velocity." http://www.newscientist.com/article/mg20026801.500-why-einstein-was-wrong-about-relativity.html Why Einstein was wrong about relativity 29 October 2008, Mark Buchanan, NEW SCIENTIST "This "second postulate" is the source of all Einstein's eccentric physics of shrinking space and haywire clocks. And with a little further thought, it leads to the equivalence of mass and energy embodied in the iconic equation E = mc2. The argument is not about the physics, which countless experiments have confirmed. It is about whether we can reach the same conclusions without hoisting light onto its highly irregular pedestal. (...) But in fact, says Feigenbaum, both Galileo and Einstein missed a surprising subtlety in the maths - one that renders Einstein's second postulate superfluous." http://henry.pha.jhu.edu/henryMinkowski.pdf "In September of 1905 Einstein published a development from relativity - the discovery of the implication that E = mc2, and in this new paper he mentions a single postulate only. But the paper contains a sweet footnote: "The principle of the constancy of the velocity of light is of course contained in Maxwell's equations." How I love that "of course!" Einstein was human! I do not know if it is true, but I recall being told that during the Middle Ages undergraduates learned to multiply and divide using Roman numerals, while the exotic Arabic numerals were reserved for the more advanced students. That is exactly what we do today in teaching special relativity. Antique postulates that are not of anything but historical interest to genuine physicists are presented to students as "Special Relativity." Some books do better than others in warning students how seemingly impossible the second postulate is; but all have the students working out true but unintuitive consequences (e.g. relativity of simultaneity) using thought experiments with of course the second postulate producing the bizarre result. A small number of texts (Ohanian, Knight, a few others) at least follow Einstein's second paper in having but a single postulate; but none do what needs to be done, which is to drop Einstein and adopt Minkowski." http://philsci-archive.pitt.edu/archive/00001661/ MINKOWSKI SPACE-TIME: A GLORIOUS NON-ENTITY Harvey R. Brown, Oliver Pooley "It is argued that Minkowski space-time cannot serve as the deep structure within a "constructive" version of the special theory of relativity, contrary to widespread opinion in the philosophical community." http://philosophy.ucsd.edu/faculty/ccallender/index_files/physics%20against%20tense.doc "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."
