New look for the blog. I change this about once a year. Happier with the stripped-down look which looks better on mobile devices. Analytics suggest almost half of the 10,000 readers of this blog a month are reading this on a mobile, so this should be a bit nicer for them.

Of course students can still get their lecture notes in the teaching pages, and the rants, which are far and away the most popular part of the site, will stay out front and centre and be archived here. No need for book images and iPad apps etc., any more, they are in the books tabs if readers are interested.
