Half way through I was thinking I'm not learning anything new, then came the connection between time and thermodynamics. Why didn't I know this before? Or did I and I have forgotten?
Anyway a short book which helped break a period where it seems I haven't read, although in reality, it's more a case of I haven't finished a book recently. Below a picture of the books I have finished reading this year, and the piles of books under my bed with just the first few chapters read!
