Crammed a lot in yesterday. Started with breakfast and a meeting with James and Dug, then a riverside cycle for a quick burst of Max Beckmann, and Anish Kapoor, at the Tate Modern, a bit of work at the library and a late afternoon seminar (on one way in which children are more logical than adults) followed by a trip to the South Bank to meet Ohna for a bite to eat and the George Piper Dances at the Queen Elizabeth Hall.

I didn't really know Beckmann's work which is lively, theatrical and comic (in style even though not always funny). Time Out says the self-portraits are best, and I agree, but I also liked the bronze sculptures.

Anish Kapoor's 'big plasticky thingy' is really impressive, taking over the big turbine hall and making you feel like climbing in.

The seminar was fascinating. It seems that kids are less likely than grownups to think that 'some cows are mammals' is false. Or, to put it the other way round, grownups are more likely than kids to make the jump to thinking 'some X are Y' must mean 'some X are not Y'. Confused? You will be.

I love the South Bank. The architecture makes you feel like you've time-warped back to a glorious age where there are always lots of people enjoying cultural activity. The people are a good mix of young and old, smart and casual, X and Y. Of course, there's some pattern here - the older ones tend to be smarter. And why are there always busloads of older folk dressed very smartly in ballgowns and evening dress? We weren't convinced that the buses had started their journey in our world. And you never know when a poet laureate will just appear and start signing books next to you.

The dances were great, btw. The first half of the evening was made up of five new pieces by top choreographers accompanied by short films about how they work. At the end of the evening they showed some out-takes and other funny bits. Soon, all dance events will have to have one.
