A Slice Of Pi

This book offers a new look at maths without the Boring Bits ... How many trillions are there in a googol? Which fractions are vulgar? What famous mathematician refused to eat beans? And which one never travelled without his pet spider in an ivory box? Mathematical theorems and equations are inextricably entangled with the great, and often eccentric thinkers who made breakthrough discoveries. Teacher and numbers expert Liz Strachan takes readers beyond the classroom, combining anecdotes, proofs and party tricks to reveal the foundations of algebra, geometry and trigonometry in a clear and entertaining style. From the Difference Engine to magic squares and from the Fibonacci rabbits to Fermat's Last Theorem, this fascinating tour of the weird world of numbers, imaginary, real or infinite, will appeal to anyone with an enquiring mind.
