[Back at work]
Most of the day was spent preparing for the semester. In research time, I spoke with Lang for a while about prioritizing the remaining work for his thesis. We decided that no more fun is permitted until the thesis is done. That's no more fun for Lang and no more fun for me. My job is to give detailed comments on the introduction to the main paper on Astrometry.net.
In the week since my last post, I have not done much research except working on long-term writing projects, and thinking about issues in stellar dynamics.
