So very tired right now. Had a frustrating morning where I couldn't even solve a convex problem. Afternoon went slightly better as the guys just basically told me the answer to almost all the questions... Now all I need is to write up the solutions tomorrow morning (hopefully there will be enough time for that).

I was going to skip Amazing Race, but then I decided not to, and I didn't regret it. It was a slightly tedious episode, but the ending was so good, even though it was so sad. And I just watched Jeopardy on tape, and Ken finally lost...hehe. The expression on Nancy's face is just priceless when she saw that Ken had the wrong answer to Final Jeopardy. End of an era that started half a year ago. Let's just hope that nobody goes a fifth as long as Ken....

I need a break.
