book review
The topic of this book  the BanachTarski Paradox  is a result so strange and counterintuitive that the author says he didn't believe it when he first saw it. The "paradox"  in fact an impeccable mathematical theorem  says that a small sphere, for example a pea, can be cut into as few as five pieces which can then be reassembled so as to make a far bigger sphere, for example the sun.

The author of this book is Statistics Editor of the Financial Times, the only newspaper in Britain to employ someone with this job title. He is therefore uniquely well placed to write this fascinating and timely book, which sets out to provide a factbased picture of the society we live in.

Anyone who has ever tried to analyse a game mathematically knows that things can get very complicated very quickly. In a game like chess, the number of possibilities for just the first three moves is already enormous, while, in poker, the roles played by chance, strategy and psychology seem to be mysteriously interlinked.

Keith Devlin is a wellknown populariser of mathematics, author of many books and appearing regularly on American radio as "The Math Guy" In this latest offering he walks us through the astounding mathematical capabilities of both plants and animals, and on to the abstract abilities of humans.

This book is a curious mixture of biography, history and mathematics, all neatly packaged into an entertaining and enlightening read. In essence it is a biography of the brilliant and eccentric mathematician, John von Neumann, who began life, much like many of the other great mathematicians, by being able to do basic arithmatic before other children could speak and with an ability to calculate exceptionally well before he even went to school.

It's never easy for me to read a work of fiction based in and around a world I'm familiar with. Quite often I find that the author will make some small error of fact, perhaps about something very minor, which then stops me from enjoying the book as a whole because I begin to wonder what other facts, in areas that I know nothing about, are also incorrect.

"Tribute to a Mathemagician" is the third book in a series of publications based on the Gathering for Gardner meetings, a regular gathering of enthusiasts who share Martin Gardner's interests in mathematics, magic and puzzle creation. Martin Gardner, the father of recreational mathematics, has influenced readers all over the world with his "Mathematical Games" column in Scientific American, which ran for 25 years.

This charming book is in its second edition (the first was published in 1994). It is about integers, with a short section for each number between 1 and 200, and a line for each between 201 and 999. There are "boxes" for interesting facts and definitions, such as "perfect number", and a few "large numbers" also make the cut, including 1729, the subject of a famous anecdote about Hardy and Ramanujan, and 10^{1000}, the googol.

Measurement is a tricky business, and rarely leaves the thing measured unchanged, as Heisenberg's Uncertainty Principle states at the quantum level. But statistician David Hand has gone back to the foundations, examining measurement right across the various disciplines: psychology, medicine, physical sciences, economics, the social sciences and elsewhere. He must treat in a unified manner scales used to measure phenomena as different as pain, retail prices and magnetism.

Infinity is more than simply the biggest ever number, and even this simple description has caused problems for mathematicians throughout the ages. From the ancient Greeks to Newton, from Newton to presentday mathematicians such as Cristian Claude and Boris Pavlov of New Zealand, infinity has posed both practical and conceptual problems.
