Well, I'm on the first day of a 'complexity summer school', put on my Manchester Uni, hosted at St. Martin's College in Ambleside, in the Lake District, and pre-emptively paid for by my lovely new department. Details may or may not remain available at the school's website.

I perhaps shouldn't have been surprised, given the nature of the topics, but out of the first three lectures, two and a quarter have been totally beyond me. I haven't done the maths. I haven't even done differentiation, which was obviously going to make things rather challenging. Oop. A few others will have to pick up on some stuff (the stochastics chap got into eigenvalues at one point, saying that if anyone had problems with it, they could check in the tutorial), but at the minute its mostly 'beeeeep' for me.
