    "closed system".

    To claim that our "organization" violates the second law is to claim that we live in a closed system. Maybe that's true about the universe, but it certainly isn't true of earth which is continually bombarded with matter and energy from outside the earth.

    A mechanical clock will run down if you don't wind it, because it's a closed mechanical system with a winding stem that interfaces to the outside. If you wind it, it keeps on ticking. That's what the second law says: there's no free lunch - it doesn't say nobody gets to eat.

    I expect the sun will rise tomorrow, and Sagan, apparently, doesn't.

      he is not arguing it violates the second law.

        He says "all" systems, not "closed" systems, and that's just plain wrong.

        •  All systems are open. (0+ / 0-)

          In thermodynamics we create virtual closed and isolated systems.  They can not really exist except as approximations.

          •  Then you're agreeing with what's being said (0+ / 0-)

            in this thread? Because the quote from Sagan begins with a statement that's only true about closed systems. If they no longer exist, he's writing gibberish.

              distorted anything can be called gibberish.  You have your straw man.  Try dealing with Sagan's position next time.

    •  Real systems are open. (0+ / 0-)

      You can only approach a closed system in a laboratory.  Even then it is only an approximation over the short term.
