Yes it does. It is of fundamental importance.leroy said:Rumraket said:Statistical thermodynamics says that the total entropy of an isolated system will on average always increase. None of the entities around us are isolated systems. Living cells aren't isolated systems, airplanes aren't isolated systems, the Earth isn't an isolated system, proteins aren't isolated systems, metabolic networks aren't isolated systems.
So the 2nd law of thermodynamics does not say the origin of life is impossible, nor that entropy can't decrease in an open system. All the entities around us are open systems. Cells are open systems. Proteins are open systems. DNA is an open system. The Earth, it's atmosphere and the oceans are all open systems.
You keep opening your mouth and making pronouncements on matters of which you know next to nothing. Just stop please.
Wrong statistical thermodynamics don’t care is the system is isolated or not
Human beings making an airplane is an instance of the laws of thermodynamics playing out. When human take actions to put together a complicated object, it is at the conversion of energy into less usable forms. You eat food that powers the processes in your brain, and the actions of your muslces, so that you can pick the parts and pick them together. In this process you generate heat through mechanical friction and the burning of organic molecules in your cells. These in turn increase the total entropy of the universe, even though locally you reduce the entropy of the parts in the junkyard into an airplane.leroy said:you can’t get an airplane form a junkyard regardless if the junk yard is open or close.
At no point is anything about thermodynamics violated. This stupid picture you have where "intelligence" somehow violates fundamental natural laws is fundamentally wrong.
Yes there is, and human beings creating an airplane is an instance of the laws of thermodynamics resulting in an airplane. The total entropy of the universe is increased as heat dissipates out in the atmosphere and surroundings. You create raise the entropy of the universe more by the simple act of moving your muscles, than you could ever wish to reduce it by carefully moving the parts in the junkyard around. There is no way around this. Maxwell's Demon is a practical physical impossibility.leroy said:This is because there are many possible combinations in which “junk” can be organized but only 1 (or few) combinations would produce something that you would call an airplane. And there is not a bias in the laws of nature where a combination that produces an airplane would be favored.
The airplane has lower entropy than the junkyard, but the surrounding atmosphere of the Earth, and the universe as a whole, will increase in total entropy, when a human being acts to put that airplane together. Because the process generates heat through friction and the chemical processes that power your cells.leroy said:This is why it is said that a junk yard (or primordial soup) has high entropy and an airplane (or life) low entropy.
The same basic principle is at work everywhere in the universe. Where there are local reductions in entropy happening, they come at the cost of greater total entropy of the system as a whole. Whether a human being assembles an airplane, or a fire burns wood to charcoal, or liquid water freezes into ice, or evaporates and leaves calcium carbonate spots in your kitchen wares. These are all examples of local reductions in entropy happening at the cost of an increase in the total entropy of the greater system. And they are possible because the local effects take place in either open or closed systems, which are themselves embedded a larger system (the universe) that is possibly isolated.
You didn't quote any equations, you gave a link to a wikipedia article on entropy, and it doesn't contradict anything I've said.leroy said:The equations that I quoted, work in both open and closed systems
And you're still bullshitting about stuff you don't understand and have no formal education in. Please just shut the fuck up and move on to a different thread on a different topic.
