Quote | Can ‘Anything’ Happen in an Open System? This is based on a 2005 online article in the American Spectator. The origin and development of life seem to violate the second law of thermodynamics in a clear and spectacular way; however, such arguments are routinely dismissed by saying that the second law does not apply to open systems, such as the Earth. The author counters this idea with the tautology that “if an increase in order is extremely improbable when a system is closed, it is still extremely improbable when the system is open, unless something is entering which makes it not extremely improbable.” In an appendix to a 2005 John Wiley mathematics text, reproduced in this chapter, the author looks at the usual equations for the second law as it applies to heat conduction and diffusion, and shows that they actually confirm this common sense interpretation, rather than the idea that anything can happen in an open system. The conclusion: “If we found evidence that DNA, auto parts, computer chips, and books entered through the Earth’s atmosphere at some time in the past, then perhaps the appearance of humans, cars, computers, and encyclopedias on a previously barren planet could be explained without postulating a violation of the second law here. But if all we see entering is radiation and meteorite fragments, it seems clear that what is entering through the boundary cannot explain the increase in order observed here.” |

"To spell it out, there's about a trillion times more entropy flux available than is required for evolution. The degree by which earth's entropy is reduced by the action of evolutionary processes is miniscule relative to the amount that the entropy of the cosmic microwave background is increased."
