There are certain days as a teacher when you know you have done your job right. For me, one of those days was today. One of the classes I teach is “Space Physics.” In this 3 credit class, my students and I go on a tour de force of the history of spacecraft and exploration of our solar system. At the beginning of the semester, none of my six students had ever watched a space shuttle launch on TV, and their interest in the class existed, but let’s just say they didn’t seem eager and excited to learn as much as they could. But today, the last day of the semester, I saw that all this had changed. These were excited students, ready to take what they had learned and run (or rather fly) with it as far as they could. For some of them, that distance was a few hundred feet straight up.
