A History of Pi

A History of Pi (also titled A History of $\pi$) is a 1970 non-fiction book by Petr Beckmann that presents a layman's introduction to the concept of the mathematical constant pi (π).

Author
Beckmann was a Czechoslovakian who fled the Communist regime to go to the United States. His dislike of authority gives A History of Pi a style that belies its dry title. For example, his chapter on the era following the classical age of ancient Greece is titled "The Roman Pest"; he calls the Catholic Inquisition the act of "insane religious fanatic"; and he says that people who question public spending on scientific research are "intellectual cripples who drivel about 'too much technology' because technology has wounded them with the ultimate insult: 'They can't understand it any more.'"

Beckmann was a prolific scientific author who wrote several electrical engineering textbooks and non-technical works, founded Golem Press, which published most of his books, and published his own monthly newsletter, Access to Energy. In his self-published book Einstein Plus Two and in Internet flame wars, he claimed that the theory of relativity is incorrect.
