Alex Through The Looking Glass - Tapa blanda

See, numbers don't have to be scary (Evan Davis)

Another sparkling romp through the world of numbers, with the inimitable Alex Bellos as your friendly, informed, and crystal-clear guide. A brilliant successor to Alex in Numberland (Ian Stewart)

To read Alex Through the Looking-Glass is to have one's mind quietly but continually blown with the knowledge that the world, so seemingly complex, is constantly conforming to patterns ... Bright children, bored with the way maths is presented, will find plenty here to jolly up their calculus classes, while those with an in-depth mathematical education may still find new gems (Sunday Express)

Alex Bellos brings the quirks and eccentricities of numbers wonderfully to life ... Each chapter has its fair share of intriguing stories, which are always followed by plenty of equations and detailed explanations. In many ways, Bellos's books remind me of the writing of Martin Gardiner, who was one of the most prolific recreational mathematicians of the 20th century and who died in 2010 (Simon Singh, Observer)

The great moments in maths, it seems, are not contemplations of chilly glories, but small, satisfying discoveries, like getting a particularly clever cryptic crossword clue, it is this friendly approach to numbers that makes Bellos so approachable; he has a way of walking the reader through a problem ... If anything, Looking Glass is a better work than Numberland - it feels more immediate, more relevant and fun (Daily Telegraph)

Fresh, fascinating and endlessly charming. A splendiferous book altogether (Tim Harford, author of The Undercover Economist Strikes Back)

From triangles, rotations and power laws, to fractals, cones and curves, bestselling author Alex Bellos takes you on a journey of mathematical discovery with his signature Wit, engaging stories and limitless enthusiasm.
