Physicists and Economists don't see eye to eye. When you're trained in one, you don't understand the other well enough to compare. But as I've been roughly trained in physics, there's a secure beauty in the things you know and understand. You can always check yourself against reality if ever you're worried. There's always a sanity check. Even when it returns an insane answer, you can be sane in accepting it.

With economics, it seems that the demand for an answer well out-strips our ability to have one. And so you have a lot of worthwhile information, but none of it built upon a bedrock comparable to physics.
