I know there's plasma and some other weird ones but look. As exciting as plasma is, we talk about water freezing at 0 degrees and boiling at 100 but I don't know when water "plasmas". It's just too far out of the way of normal things that happen to it. Common substances should freeze at one temperature, boil at another temperature, and then have a third temperature maybe between the two where they do something else. I know two state transitions is a really good and convenient number but that's exactly my problem; that makes it suspicious to me. I think it's too convenient, which means it ought to be worse. You know what I mean?
