Semester started yesterday, so the past couple of days have been a lot of last-minute rushing about getting everything ready to go. I'm TAing a senior/grad level class and I am excited to be able to have expectations of my students. Teaching intro classes is fun, but it's nice to expect people to know the basics & thus be able to spend time talking about the more interesting stuff. Some of my students this semester have been my students in the past, so I know I've got some sharp cookies. It's going to be fun & also too much C. I'm sitting in on a modern physics class this semester since I have approximate knowledge of how that stuff works but little formal/mathematical understanding. I'm used to graduate classes: the professor was discussing an example, and said, "we'll do the math for this on Friday" and I thought to myself, "but I want the math NOW!"
