Thermodynamics: the first ever ideology masquerading as science: http://web.mit.edu/keenansymposium/overview/background/index.html Arthur Eddington (THE IDEOLOGUE): "The law that entropy always increases, holds, I think, the SUPREME POSITION among the laws of Nature. If someone points out to you that your pet theory of the universe is in disagreement with Maxwell's equationsâthen so much the worse for Maxwell's equations. If it is found to be contradicted by observationâwell, these experimentalists do bungle things sometimes. But if your theory is found to be against the second law of thermodynamics, I can give you no hope; there is nothing for it but to collapse in deepest humiliation." http://philsci-archive.pitt.edu/archive/00000313/ Jos Uffink (THE SCIENTIST): "The historian of science and mathematician Truesdell made a detailed study of the historical development of thermodynamics in the period 1822â1854. He characterises the theory, even in its present state, as âa dismal swamp of obscurityâ and âa prime example to show that physicists are not exempt from the madness of crowdsâ. He is outright cynical about the respect with which nonmathematicians treat the Second Law: "Clausiusâ verbal statement of the second law makes no sense [. . . ]. All that remains is a Mosaic prohibition; a century of philosophers and journalists have acclaimed this commandment; a century of mathematicians have shuddered and averted their eyes from the unclean. Seven times in the past thirty years have I tried to follow the argument Clausius offers [. . . ] and seven times has it blanked and gravelled me. [. . . ] I cannot explain what I cannot understand." From this anthology it emerges that although many prominent physicists are firmly convinced of, and express admiration for the Second Law, there are also serious complaints, especially from mathematicians, about a lack of clarity and rigour in its formulation. At the very least one can say that the Second Law suffers from an image problem: its alleged eminence and venerability is not perceived by everyone who has been exposed to it. 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.worldscibooks.com/chemistry/etextbook/6469/6469_preface.pdf Arieh Ben-Naim (THE SCIENTIST fights with THE IDEOLOGUE): "I believe that the time is ripe to acknowledge that the term entropy, as originally coined by Clausius, is an unfortunate choice. Moreover, it is also a misleading term both in its meaning in ancient and in contemporary Greek. On this matter, I cannot do any better than Leon Cooper (1968). Cooper cites the original passage from Clausius: in choosing the word "Entropy," Clausius wrote: "I prefer going to the ancient languages for the names of important scientific quantities, so that they mean the same thing in all living tongues. I propose, accordingly, to call S the entropy of a body, after the Greek word "transformation." I have designedly coined the word entropy to be similar to energy, for these two quantities are so analogous in their physical significance, that an analogy of denominations seems to be helpful." Right after quoting Clausius' explanation on his reasons for the choice of the word "Entropy," Cooper commented: "By doing this, rather than extracting a name from the body of the current language (say: lost heat), he succeeded in coining a word that meant the same thing to everybody: nothing." I fully agree with Coopers comment; however, I have two additional comments, and contrary to Cooper, I venture into taking the inevitable conclusion: First, I agree that "entropy means the same thing to everybody: nothing." But more than that, entropy is also a misleading term...." http://bip.cnrs-mrs.fr/bip10/valevfaq.htm Athel Cornish-Bowden (THE IDEOLOGUE): "Reading Mr Valevâs postings to the BTK-MCA and other news groups and trying to answer all the nonsense contained in them incurs the risk of being so time-consuming that it takes over oneâs professional time completely, leaving none for more profitable activities. On the other hand, not answering them incurs the even greater risk that some readers of the news group may think that his points are unanswerable and that THERMODYNAMICS, kinetics, catalysis etc. rest on as fragile a foundation as he pretends....There is probably no law in science that has been tested so thoroughly, by so many people, over such a long period. (Why? Because lots of people would like it to be wrong, and if they could find a loophole it might well make them very rich; as Benno ter Kuile pointed out, an instant Nobel prize would be only a minor part of the rewards). None of them has been able to disprove it, so the only reasonable interpretation for the reasonable person is that it is true. Mr Valev thinks otherwise, and there was a great deal of discussion of this during May to September 1997, during which period Mr Valevâs scheme for tangling the threads was so successful that you will have great difficulty trying to follow any of the arguments. Suffice it to say that if Mr Valev really believed what he was saying he would not be writing nonsense on this news group, he would be building the machine that would make him the richest man in Bulgaria (or even the world)." http://www.beilstein-institut.de/bozen2004/proceedings/CornishBowden/CornishBowden.htm Athel Cornish-Bowden (THE SCIENTIST fights with THE IDEOLOGUE): "The concept of entropy was introduced to thermodynamics by Clausius, who deliberately chose an obscure term for it, wanting a word based on Greek roots that would sound similar to "energy". In this way he hoped to have a word that would mean the same to everyone regardless of their language, and, as Cooper [2] remarked, he succeeded in this way in finding a word that meant the same to everyone: NOTHING. From the beginning it proved a very difficult concept for other thermodynamicists, even including such accomplished mathematicians as Kelvin and Maxwell; Kelvin, indeed, despite his own major contributions to the subject, never appreciated the idea of entropy [3]. The difficulties that Clausius created have continued to the present day, with the result that a fundamental idea that is absolutely necessary for understanding the theory of chemical equilibria continues to give trouble, not only to students but also to scientists who need the concept for their work."
