The weather is intermittently rainy, the altitude is causing a certain amount of fatigue, and the beds are in the dorm, and predictably lumpy - but I'm having a wonderful time.
Yesterday, I built a number of devices to use in the classroom (Make & Take workshop). Today, I learned a method of quickly checking student understanding of concepts (Ranking Tasks in Physics).
The food is good, and I'm getting a lot of exercise walking around a very large campus. Let's hope I can maintain my weight loss - some years it's difficult.
