A HISTORY OF PI
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. 5Petr Beckmann holds up this mirror, 4giving the background of the times when Pi made progress — and also when it did not, because 3science was being 1stifled by militarism or religious fanaticism. The mathematical level of this book is flexible, and there is plenty for readers of all ages and interests.
