Books

I've written or co-written eleven books, some of which have appeared in several languages. The majority are about the maths of everyday life, but I've also written books on cricket, memory and creative thinking.

I give talks to adults, teenagers and children that range from small interactive workshops to keynote lectures in front of several hundred. I've also done lots of radio, including BBC Radio 4, 5Live, Radio 3 and 2, but not 1 or 6...yet.
