I went to some more lectures in the Science Festival. The first was about the psychology of magic and showed some of the tricks used by magicians to deceive us. Most interesting was a video where we were told to count the number of times the basket ball was passed between players. On second viewing though the surprising thing was a man in a gorilla suit walking through the middle of the players without anyone noticing. Then we went to a talk about the supercomputers run at Edinburgh university. These machines not only cost a lot but also use fantastic amounts of electricity to run and almost as much to keep cool, a lot of supercomputers now are using more slower lower powered chips since that keeps the electricity usage more reasonable. Finally I went to a talk on tall buildings and how they are made, mildly interesting but didn’t help me understand much about how they stay upright. Between talks Beth invited me to go to Catholic Mass, this was about the most scary event of my life. Four men stand at the front saying meaningless stuff while everyone else chants back at them, they all just know what to chant back. This is a fantastic waste of time and money, I would have hoped that these four people who get paid full time saleries to say a quarter of a mass each a day could be better put to use on pretty much anything else.
