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.


Talks & Radio

I give talks to adults 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.


Maths & Puzzles

I love any maths that contains surprises especially when it's connected to everyday life, from lottery coincidences to teabags, and from rugby kicks to Derren Brown's mind control.
