“He asked: “You are aware of the Second Law of Thermodynamics, right?” “‘You Do Not Talk About Thermodynamics?’” Rudy said nothing. “The currency of the universe, Entropy. Okay and…?” “A candle that burns twice as bright burns half as long.” “That seems unrelated, but I’ll allow it. Is that supposed to be comforting?” “I like either the lavender or cinnamon-scented ones.” “This isn’t the advice I was asking for and you know that.” “Isn’t it? You know, it doesn’t take a master’s in behavioral psychology to see you’ve some unresolved issues.” “And the universe has a tendency to devolve into chaos, so why bother controlling it, just control myself?” Rudy just continued to shoot glances at Danny’s arm. Danny kept it face down, pretending not to notice. “Rudy: Sigmund Freud meets Dr. Seuss. Thank you.”

“When I was lecturing recently to a group of cardiologists at the Mayo Clinic I said... Why is it that from the moment you enter medical school to the moment you retire, the only disorder that you will ever diagnose with a physics textbook is obesity? This is biology folks, it's endocrinology, it's physiology - physics has nothing to do with it. The laws of thermodynamics are always true, the energy balance equation is irrelevant. If someone's getting fatter I guarantee you they're taking more energy than they expend (as long as they're getting heavier). And if they're getting leaner I guarantee they're expending more than they're taking in. [It's] given, let's never discuss it again. And if you say it to your patients you're telling them nothing (University Of Colorado Medical School, May 9th 2013 - via YouTube)”

“...Why is it, that from the moment you enter medical school to the moment you retire, that the only disorder you will ever diagnosis with a physics book - is obesity?

“For a finite-size flow system to persist in time (to live), its configuration must evolve in such a way that provides easier access to the currents that flow through it.”

“For Serres, everything exists in at least three distinct broad temporalities (At 126–7) which can be further subdivided and combined in different ways. The fi rst time is the reversible, clockwork time of the classical age, when no fundamental law was thought to dictate the direction of time’s flow. The second time is the globally entropic time of the second law of thermodynamics, of Carnot’s heat engine that carries everything towards death. This thermodynamic principle was formalised in 1865 by Rudolph Clausius who, drawing heavily on Carnot’s work on heat engines, coined the term ‘entropy’ to describe the irrecoverable heat inevitably lost from any mechanical system. Laplace brings this irreversible time into the natural sciences with a cosmogony that supplements Newton’s reversible cosmology with a dimension of becoming (JVSH 36), and Darwin inscribes irreversible time at the heart of the natural sciences (JVSH 39). The eternal universe of Pascal is no more: ‘Immersed in time the universe likewise is born, develops, evolves, wears out and, perhaps, will die’ (JVSH 36).133 Time enters into science. The third time is the locally negentropic time of codes and information, preserving complexity against the general decay of order (H4 287).134 The idea of negentropy was developed in the 1930s, describing a pocket of information preserved in a wider context of entropic decay (see JVSH 136). It is a time encrusted in the living beings who ‘follow an evolution that Bergson called creative, of which we can at least say that it runs in the opposite direction to the thermodynamic arrow’ (H5 79) (Watkin 2020: 132)”

“A good many times I have been present at gatherings of people who, by the standards of the traditional culture, are thought highly educated and who have with considerable gusto been expressing their incredulity at the illiteracy of scientists. Once or twice I have been provoked and have asked the company how many of them could describe the Second Law of Thermodynamics. The response was cold: it was also negative. Yet I was asking something which is about the scientific equivalent of: Have you read a work of Shakespeare's?”

“In fact, the science of thermodynamics began with an analysis, by the great engineer Sadi Carnot, of the problem of how to build the best and most efficient engine, and this constitutes one of the few famous cases in which engineering has contributed to fundamental physical theory. Another example that comes to mind is the more recent analysis of information theory by Claude Shannon. These two analyses, incidentally, turn out to be closely related.”

“It has never been in my power to study anything, mathematics, ethics, metaphysics, gravitation, thermodynamics, optics, chemistry, comparative anatomy, astronomy, psychology, phonetics, economics, the history of science, whist, men and women, wine, metrology, except as a study of semeiotic .”

“In the eighteenth century it was often convenient to regard man as a clockwork automaton. In the nineteenth century, with Newtonian physics pretty well assimilated and a lot of work in thermodynamics going on, man was looked on as a heat engine, about 40 per cent efficient. Now in the twentieth century, with nuclear and subatomic physics a going thing, man had become something which absorbs X-rays, gamma rays and neutrons.”

“Professor Eddington has recently remarked that 'The law that entropy always increases - the second law of thermodynamics - holds, I think, the supreme position among the laws of nature'. It is not a little instructive that so similar a law [the fundamental theorem of natural selection] should hold the supreme position among the biological sciences.”

“It is possible to express the laws of thermodynamics in the form of independent principles , deduced by induction from the facts of observation and experiment, without reference to any hypothesis as to the occult molecular operations with which the sensible phenomena may be conceived to be connected; and that course will be followed in the body of the present treatise. But, in giving a brief historical sketch of the progress of thermodynamics, the progress of the hypothesis of thermic molecular motions cannot be wholly separated from that of the purely inductive theory.”

“In thermodynamics as well as in other branches of molecular physics , the laws of phenomena have to a certain extent been anticipated, and their investigation facilitated, by the aid of hypotheses as to occult molecular structures and motions with which such phenomena are assumed to be connected. The hypothesis which has answered that purpose in the case of thermodynamics, is called that of "molecular vortices," or otherwise, the "centrifugal theory of elasticity.”

“The laws of thermodynamics may be regarded as particular cases of more general laws, applicable to all such states of matter as constitute Energy , or the capacity to perform work, which more general laws form the basis of the science of energetics, a science comprehending, as special branches, the theories of motion, heat, light , electricity , and all other physical phenomena.”

“Nothing in life is certain except death, taxes and the second law of thermodynamics. All three are processes in which useful or accessible forms of some quantity, such as energy or money, are transformed into useless, inaccessible forms of the same quantity. That is not to say that these three processes don't have fringe benefits: taxes pay for roads and schools; the second law of thermodynamics drives cars, computers and metabolism; and death, at the very least, opens up tenured faculty positions.”

“Every heat engineer knows he can design his heat engine reliably and accurately on the foundation of the second law [of thermodynamics]. Run alongside one of the molecules, however, and ask it what it thinks of the second law. It will laugh at us. It never heard of the second law. It does what it wants. All the same, a collection of billions upon billions of such molecules obeys the second law with all the accuracy one could want”

“It is often said that the progression from simple to complex runs counter to the normal statistics of chance that are formalized in the Second Law of Thermodynamics. Strictly speaking, we could avoid this criticism simply by insisting that the Second Law does not apply to living systems in the environment in which we find them. For the Second Law applies only when there is no overall flow of energy into or out of a system, whereas all living systems are sustained by a net inflow of energy.”

“Physics admits of a lovely unification, not just at the level of fundamental forces, but when considering its extent and implications. Classifications like "optics" or "thermodynamics" are just straitjackets, preventing physicists from seeing countless intersections.”

“In the complex course of its evolution, life exhibits a remarkable contrast to the tendency expressed in the Second Law to Thermodynamics. Where the Second Law expressed an irreversible progression toward increased entropy and disorder, life evolves continually higher levels of order. The still more remarkable fact is that this evolutionary drive to greater and greater order also is irreversible. Evolution does not go backward.”

“The laws of thermodynamics restrict all technologies, man's as well as nature's, and apply to all economic systems whether capitalist, communist, socialist, or fascist. We do not create or destroy (produce or consume) anything in a physical sense- we merely transform or rearrange. And the inevitable cost of arranging greater order in one part of the system (the human economy) is creating a more than offsetting amount of disorder elsewhere (the natural environment).”

“The laws of thermodynamics, as empirically determined, express the approximate and probable behavior of systems of a great number of particles, or, more precisely, they express the laws of mechanics for such systems as they appear to beings who have not the fineness of perception to enable them to appreciate quantities of the order of magnitude of those which relate to single particles, and who cannot repeat their experiments often enough to obtain any but the most probable results.”

“I find the big bang, really quite fascinating. I mean, here you have all these highfalutin scientists and they're saying it was this gigantic explosion and everything came into perfect order. Now these are the same scientists that go around touting the second law of thermodynamics, which is entropy, which says that things move toward a state of disorganization.”

“Everybody can be great...because anybody can serve. You don't have to have a college degree to serve.”

“Aging is a staircase - the upward ascension of the human spirit, bringing us into wisdom, wholeness and authenticity. As you may know, the entire world operates on a universal law: entropy, the second law of thermodynamics. Entropy means that everything in the world, everything, is in a state of decline and decay, the arch. There's only one exception to this universal law, and that is the human spirit, which can continue to evolve upwards.”

“I don't. We've had three technological revolutions that have changed the course of human history, all driven by physics. In the first, the industrial revolution, physicists developed Newtonian mechanics and thermodynamics, which gave us the steam engine and machine power. The second technological revolution was the electricity revolution. That gave us radio, television, and telecommunications. Then, physicists developed the laser and the transistor.”

“Everybody can be great...because anybody can serve. You don't have to have a college degree to serve. You don't have to make your subject and verb agree to serve. You only need a heart full of grace. A soul generated by love.”
