http://philsci-archive.pitt.edu/archive/00000313/ Jos Uffink: "The Second Law made its appearance in physics around 1850, but a half century later it was already surrounded by so much confusion that the British Association for the Advancement of Science decided to appoint a special committee with the task of providing clarity about the meaning of this law. However, its final report (Bryan 1891) did not settle the issue. Half a century later, the physicist/philosopher Bridgman still complained that there are almost as many formulations of the second law as there have been discussions of it (Bridgman 1941, p. 116). And even today, the Second Law remains so obscure that it continues to attract new efforts at clarification. A recent example is the work of Lieb and Yngvason (1999)......The historian of science and mathematician Truesdell made a detailed study of the historical development of thermodynamics in the period 1822-1854. He characterises the theory, even in its present state, as 'a dismal swamp of obscurity' (1980, p. 6) and 'a prime example to show that physicists are not exempt from the madness of crowds' (ibid. p. 8).......Clausius' 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.......A more important objection, it seems to me, is that Clausius bases his conclusion that the entropy increases in a nicht umkehrbar process on the assumption that such a process can be closed by an umkehrbar 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.......On many occasions Clausius was criticised by his contemporaries. I do not know if, in his own time, he was criticised in particular for his famous formulation of the second law as the increase of the entropy of the universe.39 However, Kuhn (1978, pp. 13-15, p. 260) has pointed out the remarkable fact that in the book (Clausius 1876) he eventually composed from his collected articles, every reference to the entropy of the universe and even to the idea that entropy never decreases in irreversible processes in adiabatically isolated systems is deleted! The most general formulation given to the second law in this book, which may be regarded as the mature presentation of Clausius' ideas, is again the relation (10), where the system is supposed to undergo a cycle, and entropy increase is out of the question. We must conclude that in the work of Clausius and Kelvin the connection between the second law and irreversibility is extremely fragile. Kelvin claimed that the irreversibility of all processes in nature is a necessary consequence of his principle, but gave not a shred of argumentation for this claim. His later versions of the second law were even completely disconnected from the arrow of time. Clausius does give argumentation, but it is so untransparent and dependent on implicit assumptions that his famous general conclusion (all processes in nature proceed in the 'positive' direction, i.e. the direction of entropy increase) cannot be considered as established......Conclusion: the goal of Planck's approach is to take the phenomenon of irreversibility of natural processes as the essential element of the second law. But his claim to have derived a formulation of universal generality cannot withstand scrutiny. Besides, this emphasis on irreversibelity and the universal validity of the second law actually remains sterile in Planck's own work. The final part of his book, which is devoted to applications of the second law, only discusses equilibrium problems......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." This "RED HERRING" destroyed, roughly speaking, half of theoretical science. The demolition has been completed by Divine Albert and his criminal cult: http://www.perimeterinstitute.ca/pdf/files/975547d7-2d00-433a-b7e3-4a09145525ca.pdf Albert Einstein: "I consider it entirely possible that physics cannot be based upon the field concept, that is on continuous structures. Then nothing will remain of my whole castle in the air, including the theory of gravitation, but also nothing of the rest of contemporary physics." http://www.bnl.gov/community/Tours/EinsteinPics/Einsteine.jpg http://www.haverford.edu/physics-astro/songs/divine.htm http://www.physicstoday.org/vol-58/iss-7/images/devine_einstein.mp3 Pentcho Valev
