This is a beautiful book. The pictures keep the reader engaged in a colourful mathematical journey. It is written in an engaging style suitable for over 11’s but also contains ideas that are likely to interest most adults (without the need for a refresher course, since the book does a good job of being self-contained). [...] Although a mathematician would likely be aware of many of the concepts the book presents, I would still recommend it both as a tool to intrigue others (it makes a great ‘coffee table’ book) and also since it contains many imaginative explanations and original arguments. The illustrations and narrative keep the reader entertained and make the book hard to put down." - London Mathematical Society Newsletter"This is a lovely book… Although a certain affinity with mathematical reasoning is needed the book can be read by almost anyone." - Teun Koetsier, Zentralblatt Math
