We started unit 2 of the AH course today and I mentioned that it was Benjamin Franklin who introduced the terms positive and negative to describe electrical charges. Our friends at xkcd have a cartoon about it.

black hole talk
The Astronomer Royal for Scotland, Prof. John Brown, will be in Thurso on Tuesday 10th November. He’s giving a talk on black holes at the Pentland Hotel as the guest of the local Institute of Mechanical Engineers. We’ve just started to look at this topic in class and I hope some of you will be able to come along. See the attached poster for more details.
