The classic layman's history of the mathematical constant -- "A pure delight... Entirely offbeat, which gives it its charm" (The Denver Post).

"A very readable account." -- Science
"A cheerful work." -- Scientific American

The history of pi, says the author, though a small part of the history of mathematics, is nevertheless a mirror of the history of man. Petr Beckmann holds up this mirror, giving the background of the times when pi made progress and also when it did not, because science was being stifled by militarism or religious fanaticism. The mathematical level of this book is flexible, and there is plenty for readers of all ages and interests.
