Physicist and popular science author Simon Singh explores the numbers and concepts that lie at the heart of some of the trickiest problems in mathematics, revealing their history, significance and unique qualities.

Beginning with zero - which, amazingly, wasn''t invented until 400 BC and then took thousands of years to catch on - he goes on to serve up a slice of pi, uncover the hidden beauty of the Golden Ratio, reveal the reality behind the imaginary number, and explain why some infinities are bigger than others...
