News From This Past Week
Early in the week: enough of my rocks and stuff arrived for me to start playing with it (or so I thought). Turns out the chrysocolla isn't anywhere near as gorgeous as the picture made it out to be and the amethyst is still part of a geode matrix. So, I figured that I would try to remove the amethyst from its matrix; I plug in my new dremel, put in a nice small bit, and grind for a bit. The bit snaps in half. I try another bit. This one is in an odd shape; it is bulbous with a flat plate on top. The plate works like a knife edge, but after grinding some with this bit it seems that all the diamond has come off. Hopefully that's not truly the case. I put the stuff away -- I need to purchase a different tool (a diamond cut-off wheel) for this job.
Thursday was my birthday, but it was really nothing special. In fact, it followed the template laid down by last Thursday. I again slept through the morning recitation (I'm not entirely sure there was one anyway -- there was a test on Wednesday). I slept so late that I almost slept through racquetball too; I got a full twelve hours of sleep. This week, however, I lost every game of racquetball except the very last one I played. I attribute this to lack of sleep -- not that night but
Tuesday night and Wednesday morning: I had a lab report to write (again). Yes, the lab was great fun this cycle. No, the write-up wasn't particularly hard. However, the write-up did end up being 14 pages including 4 pages of appendices and two graphs. Appendix 3 was nothing but MathType. I had a whole lot of partial derivatives and error propagation to calculate.
The best day of my week was Yesterday (Saturday): I woke up early and proctored for the physics section of the Science Olympiad. The guy in charge of that physics section just so happens to play baritone with me in the band, and he asked me to volunteer. My responsibilities included making sure the competitors could use the LoggerPro software to take data, answering questions that wouldn't give away answers, and grading the papers afterwards. Now, it's rather difficult to grade papers when there is no "right answer". The setups were different (if only very slightly), so each group might gather different data. Furthermore, some groups didn't show their work, and some data was just too good to be true. For instance, they had to calculate the mass of the SAME OBJECT two different ways, and no math appeared on the page. Nobody who showed their work got exactly the same answer for those two problems, and several groups were off by a factor of three. Those groups got full credit. One group (with no math shown) had exactly the same answer for both and I had no choice but to pick one and mark it wrong. Another group calculated both answers, but chose to use only one of their solutions for both answers. I had to mark one of those wrong too. And then there were tie breakers. For first through fifth places, there could be no ties -- but we had two groups with perfect scores, and the teams that would take fourth and fifth places both had 27 points. There were special "tie breaker" questions on each part of the competition, but these four groups each got every tie breaker question correct. After struggling for a bit we found a criteria that fit both ties, and sorted the teams out. Final result: I win a tee-shirt. Final result of the Olympiad: I haven't the slightest idea.
And then there's today: my Dad's coming through to celebrate my birthday somehow. Also, I have to do laundry. Desperately.
