Yes, isn't she? The funny thing is, I had a teen volunteer teaching an astronomy class at the library, and he was talking about all this stuff - comets, planets, how the sun formed, fusion - everything you see here! I'm going to show him this one on Tuesday (showed him Flanders and Swann last week, and he laughed! Do you know it? If not, google Flanders and Swann First and Second law of thermodynamics. It's a hoot!)
