Physics

I subbed for the Physics teacher today. I love his classes. First period, he has an Algebra class, but there are only 13 kids in it. There were more last semester, but apparently some have moved elsewhere. It makes for a really nice class. The rest of the day is Physics and AP Physics kids. They're all pretty self-motivated, so I plop a movie in, and they know what to do. He always gets really interesting movies, too. Today, it was a mythbusters episode with an airplane on a treadmill. I watched it three times, and I'm still certain that they didn't understand what myth they were trying to bust, but whatever. There was another section with cockroaches and fruit flies and radiation (oh, my!), and that was interesting, too.

I actually had to get up this morning, so now I'm totally pooped. I'll leave you with this:
