if magic was a science, every aspect of it would be completely misnamed. Water magic would actually have more to do with colors or something, but it just so happens there's a lot of it naturally in rivers so it got called water magic. Fire magic wouldn't be truly magic at all but particular magically-triggered applications of well-understood chemistry. Life magic would actually show up in all kinds of non-living things.
@Felthry Good!
I do like the idea of similar happening with magic. :-)
