Was yesterday 25th March 2017 and went very well! There must have been around 100 people listening in Blackwell’s Marquee, on a beautiful sunny spring day. There was no electrical power and so no sound system; but I projected my voice to engage the audience. There were some interesting questions at the end – ranging from the emission mechanisms of pulsars, to the way that galaxies look when they are 13 billion light years away. Several books signed. Verdict: a very positive experience!
