Thermodynamics Quotes

The algebraic sum of all the transformations occurring in a cyclical process can only be positive, or, as an extreme case, equal to no

Rudolf Clausius

...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...

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)

The existence of matter and energy in the universe did not require the violation of energy conservation at the assumed creation. In fact, the data strongly support the hypothesis that no such miracle occurred. If we regard such a miracle as predicted by the creator hypothesis, then the prediction is not confirmed.

Victor J. Stenger

The fundamental laws of the universe which correspond to the two fundamental theorems of the mechanical theory of heat.1. The energy of the universe is constant.2. The entropy of the universe tends to a maximum.

Rudolf Clausius

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?

C.P. Snow

Q. You do not consider your statement a disloyal one?A. No, sir. Scientific truth is beyond loyalty and disloyalty.Q. Can you prove that this mathematics is valid?A. Only to another mathematician.Q. Your claim then is that your truth is of so esoteric a nature that it is beyond the understanding of a plain man. It seems to me that truth should be clearer than that, less mysterious, more open to the mind.A. It presents no difficulties to some minds. The physics of energy transfer, which we know as thermodynamics, has been clear and true through all the history of man since the mythical ages, yet there may be people present who would find it impossible to design a power engine. People of high intelligence, too.

There ain't no such thing as a free lunch.
