Sounds like a thing we talked about in a philosophy class I took. You have a room, with nothing but a blank piece of paper in it. There is one thing in the room. You fold the paper. There is now a crease in the paper. It is still in the room. How many things are in the room? A "crease" (like the corner of a table) is a distinct thing, yet it is part of the paper. There is no increase in mass in the room. Yet the crease remains.

    The truth is there are already many things in the room. Walls, air, paper. Gravitational influence. The arrangement is rife with mass. Between the Planck lengths are quantum fluctuations. A crease introduces a new arrangement of some of this, and the energy required to do so increases entropy. In other words, this philosophy exercise seems completely useless other than putting ignorance on full display.

    Ideas are nouns. This philophical quandary, I posit, is solved in the mere definition of what a thing is. A thing is a noun. A noun is a person, place, object, or idea. A crease in this paradigm is an idea. It is this a thing. There are 2 things in the room. There's more, though. There's air presumably. There's walls? What are they made of? Are they painted? How about the floor? A stale fart? Confusion over the number of things in the room? Still, all nouns.

    Information and entropy changed, if you melt ice figures to refrozen the water again you go the other way around, but you have introduced/extracted things during the process, so I stop seeing the philosophical wonder. To begin with "how many things are in the room?" an in-depth list should include all the energy in all their forms, including matter and organisation, and when you perform processes that change this you logically vary the full list of things in the room.

    Can the crease exist without the paper? Then in my opinion, it isn’t a separate thing.

    What if you fold it into a paper plane or boat? In that case would you go from two things to one?
