For an hour's break each day, I have been watching a documentary from the vast stock of them we have. Today's was a US film about the mathematician Paul Erdos based on the article that eventually became Paul Hoffman's The man who loved only numbers. It is ages since I last read a book on "proper" mathematics (rather than the sort of maths I need for work) and so I had a good look through my library this afternoon, selecting perhaps half a dozen books of interest.
But in the end I actually chose a mathematics-based novel, David Eavitt's The Indian Clerk, about Ramanujan and Hardy.
One of my favourite photos - GH Hardy at an Oxford-Cambridge rugby match when he was 64.
