"If one times one equals one that means that two is of no value because one times itself has no effect. One times one equals two because the square root of four is two, so what's the square root of two?

I'm pretty sure nobody anywhere in the real world is taught that the square root of 2 is 2 just because the square root of 1 is 1. Scaling just isn't mysterious, and I doubt it ever was.<p>No wonder Joy changed the subject to something a little easier and completely unrelated.<p>This is just frustratingly stupid.
