    Hmm I would say the reverse.

    Edit

    Guess I have age dyslexia. I thought text was the other way around.

    Carry on

    I’ve always had some trouble with the notion that “the universe always becomes more chaotic”. Isn’t the universe always on its way to having a perfectly evenly distributed layer of energy, and isn’t that quite orderly?

      Think of a box with 4 particles a, b, c and d. If every particle is on the left side of the box, then there is only 1 way to divide them up. [(a, b, c, d), ()]

      If there are 2 particles on the left side of the box and 2 particles on the right side of the box, then there are 6 ways to divide them up:

      [(a, b), (c, d)]
      [(a, c), (b, d)]
      [(a, d), (b, c)]
      [(b, c), (a, d)]
      [(b, d), (a, c)]
      [(c, d), (a, b)]

      In total you’ve got 16 possible arrangements, the 2-2 state has the “highest” entropy because you’re more likely to end up with the one that takes up 6/16 arrangements.

      Here’s a good way to visualize chaos vs order in this context. Imagine you have a thousand marbles neatly stacked in a pile like cannonballs are. That’s order. They operate as one entity. If you want to move the stack, you must move them all at once and very carefully.

      Now imagine those thousand marbles all strewn about your house. They are now a thousand different entities. You can’t interact with all of them at once anymore.

      You bring order back to the system by stacking the marbles again. It takes a lot of energy to stack them, and, with enough of it, you can return the marbles back to one entity.

      The notion is that entropy increases. That is, the amount of energy you can extract to do work decreases. You need differentials to do work, for example a water wheel works because water at elevation has potential energy which you can use to turn the wheel as it flows downhill to a lower potential energy. When everything is evenly distributed, you can’t extract any more energy to do work.

        Oh yes, I understand that. My issue is with describing that as “chaos” or “disorder”.
