from the fourth edition CWNA study guide:

The sun is often used as an analogy of an isotropic radiator...certain theories in physics-such as the hairy ball theorem-would even exclude the Sun...

I've taken several physics classes, but never once was hairy ball theorem mentioned. Disappointing.

I would have been tempted to tell the prof: "Hey, I got your hairy balls right here"!

[wellarmedsmurf]

That was certainly my first thought...

I couldn't believe it was real...
