Oh, thanks. But what's the problem of using the familiar notion of mapping?

Yes, but wouldn't you deduce it from that figure?

Yes, that's why I asked if it spins. I showed the reason why I thought that.

@Casteels I guess that I thought something I'm unable to explain. But as a pointed in the text, I guess I understood it right now.
