Hello to you,
long time no see. How are you?
I very much liked how you handle the topic. And also pleased that you talk about systems :)
Since disorder cannot be understood without order, they are mutually dependent. When a blob of ink falls into the water, we see a random arrangement of streaks in the water (which look beautiful), we see a certain order (or arrangement of molecules that are still separated), in other words, we can make a distinction between the coloured ink molecules and the clear water. The disorder is "perfect" when water and ink have mixed into a single colour and we cannot make a distinction.
We would have a beautiful mess if all the pages of all the books in a library were mixed together. Or all the letters of the pages of a book would be mixed up.
As I have understood order (may be wrong), it lies in distinguishing things from each other.
I suppose we live in a universe where there is order and disorder, and concede the possibility that we could be heading towards order on the one hand as well as disorder on the other, depending on how much we increase or decrease the space we want to look at (like I understand, you already have said in other words?).
