It has been a bit of a week. I am just back from the Congress Centre – which is a hall underneath Congress House, the headquarters of the TUC – where I was a late stand-in as a speaker on the ATLAS experiment at an impressive “Instant Expert” event organised by New Scientist. Quite a lot of people had decided that learning about particle physics was a good way to spend a Saturday and of course I agree. It was a very engaging audience, lots of fun.
