Teaching is a great experience! I have been teaching since 1995; mathematics, statistics, computer programming languages, physics, numerical analysis, you name it… It is definitely the best way to learn, and to have a deep understanding of the most basic concepts. Here is a list of the courses I have been teaching professionally in my astronomy career.
