Exams

Posted by Martin Orr on Monday, 05 June 2006 at 08:36

I am now half way through my exams - two gone and two to go. The first did not go as well as I had hoped - the questions just took a long time. The second one, which I had expected to be the hardest, turned out to be easy and I completed it in just over two hours (out of three). There are two more today and tomorrow. There are some strange things like the fact that the invigilators wear gowns (although in Oxford the students have to wear academical dress, at least while entering and leaving the exam hall), and they began by addressing us as "ladies and gentlemen".

I was reading that the prime minister, shortly after taking office, has to prepare secret instructions which are carried on the UK's nuclear-missile submarines; should they be unable to detect any sign of life from the UK for several days, the captain of the submarine on patrol will open the instructions and carry them out (although it's hard to see who the missiles would be targetted at post-Cold War). Anyway this makes me wonder: politicians probably give little thought to this area of responsibility until suddenly it hits them when they become prime minister, and certainly the electorate don't consider who they would trust to make such decisions when voting. So I suppose the question is what makes the prime minister better qualified than anyone else to make such decisions, and to have them carried out even after the country has been completely destroyed? I remember a science fiction book which contained a planet who left decisions about whether to go to war up to their military commanders and were astonished at the idea of giving politicians a say.

More musings

Two weeks today until exams; the past papers seem to be reasonably doable - at least when you are used to olympiad problems that take hours each. We are still getting some lectures as well, of which the most interesting and hardest are on topology; I have been spending quite a bit of time thinking about this and learning it by discovery. (Very briefly, topology is the study of continuous maps: you start off with some space or surface, then map each point from that space to a point in some other space; the map is continuous if points that started off close together end up close together.)

There have been three TCMS concerts in the past couple of weeks, including a special one in the Wren Library instead of our normal venue of the chapel. That meant lots of moving of chairs from the chapel store to the library. It's a nice building but a slightly odd concert venue; actually both the Wren Library and the chapel are very long and thin, which seems to me a strange shape for a chapel.
