Computer woes.

Sorry for my absence this week, my laptop is experiencing another attack of the "computer troubles always strike at the worst time" variety. Some of my keys randomly stopped working, making it rather difficult to write. (The on-screen virtual keyboard just doesn't cut it as a fast or efficient manner...) I'm borrowing a USB keyboard for the rest of the semester till I can get it looked at, so I ought to be able to update here again more frequently. (Although probably not this weekend, as I have a humongous take-home test in Optics due on Tuesday. And I'm driving for a summit tour on Saturday...)
