Rise and Fall

An odd duck of a day, this Thursday. I was bothered for various reasons, and it didn’t help that I had a disturbed sleep last night. Physics went ok this morning, but maths was an utter disaster. My maths textbook kept teaching me new things, giving example questions relating to the new knowledge, then setting problems that were nothing like the examples! I don’t mind that if it’s done gradually, but there was no help at all. Finding the centre of mass of an irregular shape, for example. That’s easy. There’s a question asking that, then the next question says ‘What are the co-ordinates of the centre of mass of a piece of wire bent into the shape of the previous question’. What? How do I calculate that? I’m sure it’s easy, but there’s nothing even approaching a hint, and there’s no working in the answer. So that was confusing me, and in the end I just gave up. Which was wrong of me. There’re only 50 days or so until the exams start, so now isn’t the time to be struggling.

Dancing this evening was interesting, as there were 6 of us! I had a harem. I wanted to get t-shirts printed, but the girls weren’t terribly enthusiastic. Odd, that. The other four girls hadn’t been before, so Lynsey and I were demonstrating the various dances. It was fun! Worryingly, they picked it up rather quickly. That’s not the idea at all! We’ve taken weeks learning all those steps 🙂 I think we took over a good quarter of the dance floor, especially on the new chasse (is that the correct word?). We were dancing for far longer than everybody else in the class, and the teachers even took requests for music we wanted. We tried a fast jive at the end, which was exhausting but great fun.

I must have an early night tonight. Must. No getting sucked into flickr browsing or boingboing‘s tributarial links.
