1. I’m on Google+ a lot these days. It’s now definitely my social medium of choice. Come and join in!
2. Coming out of discussions on G+, I cowrote a piece with John Baez on Babylonian mathematics and the square root of 2, which is now up on John’s blog Azimuth. (I can’t resist adding that John was also kind enough to write a flattering review of Maths 1001.)
3. And by no means least… I have a new book out! It’s called The Maths Handbook. I’ve been chatting about it, and maths in general, with Daniel Fraser on the Quercus Couch.
