Where's Willie when I need him?

Turn out the lights, the party's over,
They say that all good things must end...

And so it goes, I'm back at work today. This semester I teach some pretty neat stuff- electricity, color, Newton's Laws. But, it's also my least favorite stuff. Maybe it's because I hate having to teach math to the kiddos. Yeah, I know, they should know it.
Right.
I get to talk about space travel this semester, so that's fun. And the Theory of Gravity. Yeah, it's a theory. Anyone that wants to doubt gravity? Feel free to float away. Oh yeah, magnetism too. We bought this cool gizmo that shows the magnetic field of a magnet in 3D. Woot!

So, sharpen your pencils, tie your shoes, and get ready for the bell!
