Alex’s Adventures in Numberland/Here’s Looking at Euclid.

The book is written for the general reader. It’s my journey as I travel around the world meeting characters who bring mathematical ideas to life. The pages contain reportage, history and mathematical proofs.

The subject areas I discuss include the cognitive psychology of numbers, number systems, number bases, the abacus, Euclidean geometry, origami, arithmetic, pi, algebra, logarithms, slide rules, sequences, prime numbers, puzzles, magic squares, probability, statistics, non-Euclidean geometry and infinity

A previous website contained the appendices and notes and chapters, which are not included in the US edition. If you would like them, please email me at and I will send them to you.

A mathematical wonder that will leave you hooked on numbers…It’s hard not to get swept away by Bellos’s enthusiasm
Daily Telegraph
Original and highly entertaining.
Sunday Times
A page turner about humanity's strange, never easy and, above all, never dull relationship with numbers
New Scientist

Outstanding ... The style is laced with humour, but at all times, the star of the show is mathematics
Ian Stewart, Prospect
It is to be hoped that the uncountable delights of Bellos’s book, its verve and feeling for mathematics, convey its enchantments to a new generation.
Times Literary Supplement
Intellectual entertainment of the first order.
