Proofs from THE BOOK

Martin Aigner

Proofs from THE BOOK is a book of mathematical proofs by Martin Aigner and Günter M. Ziegler. The book is dedicated to the mathematician Paul Erdős, who often referred to “The Book” in which God keeps the most elegant proof of each mathematical theorem.

During a lecture in 1985, Erdős said, “You don’t have to believe in God, but you should believe in The Book.”
