> because if you know the right choice wihout being able to explain why But teaching isn't simply being able to explain why something is the way it is. It's more than that. I could explain to you why planets move the way they do by using the language of tensor fields built up out of tensor products mapping vectors to their duals. It would be a thoroughly accurate definition of why we see the movement we see but it would not necessarily be a good way to teach. Particularly if the recipient of the teaching wasn't familiar with the formalism of general relativity. It's this aspect, that teaching is more than simply understanding that makes me think it potentially could be orthogonal to mastery of a subject.
