A public lecture I went to held by Durham Universities Mathematical Society. Only a small group of us went but it was a nice informal affair. I certain Justin was most impressive with the offering of food and drink at a lecture. He only wishes that all his lecture were like that. He never stops eating.
I've stolen the lecture slides off the MathSoc's website, so that I can still find them.Slide 1-2, Slide 3-4, Slide 5-6, Slide 7-8.
