Who Will Fix Dead Physics?

Sabine Hossenfelder: "Research perversions are spreading. [...] Sarewitz concludes that academic science has become "an onanistic enterprise." [...] As one of the academics who believe that understanding how nature works is valuable for its own sake, I think the cure that Sarewitz proposes is worse than the disease. But if Sarewitz makes one thing clear in his article, it's that if we in academia don't fix our problems soon, someone else will. And I don’t think we'll like it." http://backreaction.blogspot.fr/2017/12/research-perversions-are-spreading-you.html

Yes, zombie physics cannot last long:

Leonard: "I know I said physics is dead, but it is the opposite of dead. If anything, it is undead, like a zombie."

I sent this comment to Hossenfelder's blog but she did not approve it of course:

Let me only add that while insignificant research is thriving, potential major breakthroughs remain unnoticed, as if Orwell's "crimestop" is totally obeyed nowadays. Here is a perpetual-motion machine of the second kind announced, somewhat euphemistically, by the University of Arkansas - the scientific community couldn't be more silent:

"A Potential Source of Clean, Limitless Energy"

The same story in 2002:

Nature 2002: "Second law broken. Researchers have shown for the first time that, on the level of thousands of atoms and molecules, fleeting energy increases violate the second law of thermodynamics. [...] They found that over periods of time less than two seconds, variations in the random thermal motion of water molecules occasionally gave individual beads a kick. This increased the beads' kinetic energy by a small but significant amount, in apparent violation of the second law." http://www.nature.com/news/2002/020722/full/news020722-2.html

Scientific American 2002: "Second Law of Thermodynamics Violated. [...] ...the water molecules interacted with the bead in such a way that energy was transferred from the liquid to the bead. These additional kicks used the random thermal motion of the water to do the work of moving the bead, in effect yielding something for nothing. For periods of movement lasting less than two seconds, the bead was almost as likely to gain energy from the water as it was to add energy to the reservoir, the investigators say." https://www.scientificamerican.com/article/second-law-of-thermodynam/

Unless false fundamental principles - Einstein's constant-speed-of-light postulate and the second law of thermodynamics - are replaced with their true alternatives, physics will continue to be stone dead:

Joao Magueijo: "Lee [Smolin] and I discussed these paradoxes at great length for many months, starting in January 2001. We would meet in cafés in South Kensington or Holland Park to mull over the problem. THE ROOT OF ALL THE EVIL WAS CLEARLY SPECIAL RELATIVITY. All these paradoxes resulted from well known effects such as length contraction, time dilation, or E=mc^2, all basic predictions of special relativity. And all denied the possibility of establishing a well-defined border, common to all observers, capable of containing new quantum gravitational effects." Faster Than the Speed of Light, p. 250 http://www.amazon.com/Faster-Than-Speed-Light-Speculation/dp/0738205257

Clifford Truesdell, The Tragicomical History of Thermodynamics, 1822-1854, p. 6: "Finally, I confess to a heartfelt hope - very slender but tough - that even some thermodynamicists of the old tribe will study this book, master the contents, and so share in my discovery: Thermodynamics need never have been the DISMAL SWAMP OF OBSCURITY that from the first it was and that today in common instruction it is; in consequence, it need not so remain." [...] p. 333: "Clausius' verbal statement of the "Second Law" makes no sense, for "some other change connected therewith" introduces two new and unexplained concepts: "other change" and "connection" of changes. Neither of these finds any place in Clausius' formal structure. 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." https://www.amazon.com/Tragicomical-Thermodynamics-1822-1854-Mathematics-Physical/dp/1461394465

Jos Uffink, Bluff your way in the Second Law of Thermodynamics: "I therefore argue for the view that THE SECOND LAW HAS NOTHING TO DO WITH THE ARROW OF TIME. [...] Before one can claim that acquaintance with the Second Law is as indispensable to a cultural education as Macbeth or Hamlet, it should obviously be clear what this law states. This question is surprisingly difficult. 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. And EVEN TODAY, THE SECOND LAW REMAINS SO OBSCURE that it continues to attract new efforts at clarification." http://philsci-archive.pitt.edu/313/1/engtot.pdf
