Top 68 Thermodynamics Quotes & Sayings - Page 2

And when my body shall cease, my soul will still be yours, Claire? I swear by my hope of heaven, I will not be parted from you." The wind stirred the leaves of the chestnut trees nearby, and the scents of late summer rose up rich around us; pine and grass and strawberries, sun-warmed stone and cool water, and the sharp, musky smell of his body next to mine. "Nothing is lost, Sassenach; only changed." "That's the first law of thermodynamics," I said, wiping my nose. "No," he said. "That's faith.

Evolution in the biosphere is therefore a necessarily irreversible process defining a direction in time; a direction which is the same as that enjoined by the law of increasing entropy, that is to say, the second law of thermodynamics. This is far more than a mere comparison: the second law is founded upon considerations identical to those which establish the irreversibility of evolution. Indeed, it is legitimate to view the irreversibility of evolution as an expression of the second law in the biosphere.

There's no evidence whatsoever that Darwin had anything useful to say or anything to say period about how life began or how the universe began or how gravity began or how physics began or fluid motion or how thermodynamics began. He had nothing to say about that whatsoever.

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.

Tell me it's never been done. Because the only real laws in this world-the only things we really know-are the two postulates of relativity, the three laws of Newton, the four laws of thermodynamics, and Maxwell's equation-no, scratch that, the only things we really know are Maxwell's equations, the three laws of Newton, the two postulates of relativity, and the periodic table. That's all we know that's true. All the rest are man's laws

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.

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.

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.
