Entropy only increases on average. You can decrease it locally, for example, making steel from iron ore. You generate heat, so you still get a net increase, but you could easily redefine your boundary to only include the local decrease in entropy (the steel from ore).
- Rury 4y agoYes, but like you said, that requires re-drawing your boundaries. It doesn't really defy the direction of entropy, it only appears that way from having changed scope.
