Back in 2008, Simon Willerton and Eugenia Cheng from Sheffield University decided to put together a series of videos (http://www.youtube.com/user/TheCatsters#p/u ) to teach the world about category theory. So impressed were we by their lucid and good humoured explanations that we decided to invite them both to come and give talks. To our great delight they both agreed!

Simon Willerton will be giving the first talk. This will take place in MS.02 this Wednesday, where as usual there will be food and drink available afterwards.

Simon's has told us his talk will be on " measuring the size of metric spaces - sets with a notion of 'distance' - and how that might lead to pure algebra having applications in ecology." The talk should be fun and will be accessible to all undergrads.

See you all on Wednesday!
