Well, I have good news and bad news. First the good. I finally passed my department's PhD qualifier exam. I passed the structures and the dynamics on the first try, but had to have an oral exam to prove my fluids prowess. Now the bad. I'm mentally exhausted after cramming fluids for the better part of two weeks. I'll have my roundtable contribution up this weekend along with a post I've been working on for a couple of weeks.
