Quotes About Thermodynamics

Time sits at the center of the tangle of problems raised by the intersection of gravity, quantum mechanics, and thermodynamics.

Only where there is heat is there a distinction between past and future.

This reads: "Delta S is always greater than or equal to zero," and we call this "the second principle of thermodynamics

entropy, as Boltzmann fully understood, is nothing other than the number of microscopic states that our blurred vision of the world fails to distinguish.

Only where there is heat is there a distinction between past and future. Thoughts, for instance, unfold from the past to the future, not vice versa—and, in fact, thinking produces heat in our heads. . . .

It is always heat and only heat that distinguishes the past from the future.

The difference between past and future only exists when there is heat.

Whenever you consider a phenomenon certifying the passage of time , it is through the production of heat that it does so. There is no preferred direction of time without heat.

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.

Heat thus occupies a unique position in the hierarchy of energies: all other forms of energy can be completely converted to it, but its conversion into other forms can never be complete, as only a portion of the initial input ends up in the new form.

The second law of thermodynamics, the universal tendency toward heat death and disorder, became perhaps the grandest of all cosmic generalizations – yet also one of which most non-scientists remain ignorant.

Finally, the third law of thermodynamics, initially formulated in 1906 as Walther Nernst's (1864–1941) heat theorem, states that all processes come to a stop (and entropy shows no change) only when the temperature nears absolute zero (–273°C).

So the second law is merely probabilistic. Statistically, everything tends toward maximum entropy.

They meant to bring back together, as a unified subject, the discipline that had been subdivided for undergraduates into mechanics, electromagnetism, thermodynamics, hydrodynamics, and optics.

The second law, then, is the tendency of the universe to flow from less likely (orderly) to more likely (disorderly) macrostates.

Entropy—already a difficult and poorly understood concept—is a measure of disorder in thermodynamics, the science of heat and energy.

First law: The energy of the universe is constant. Second law: The entropy of the universe always increases.

Rudolf Clausius coined the word in 1865, in the course of creating a science of thermodynamics. He needed to name a certain quantity that he had discovered—a quantity related to energy, but not energy.

However inventive humans turn out to be, they will never invent their way around the laws of thermodynamics. That fundamental truth is denied by standard infinite-growth theory, which blithely projects productivity gains from technological innovation indefinitely into the future.

S—The Second Law of Thermodynamics

Second Law states, among other things, that the universe is running out of usable energy.

The Second Law is also known as the Law of Entropy

Thermodynamics is the study of matter and energy

I was especially fascinated by the second law of thermodynamics, which holds that entropy virtually always increases in a closed system. Entropy is a measure of disorder or uselessness. In lay terms, this means that progress stalls or declines when something is walled off from the outside world. Usually
