Inside PFTB (Proofs from The Book) is indeed a glimpse of mathematical heaven, where clever insights and beautiful ideas combine in astonishing and glorious ways.
The style is clear and entertaining and the proofs are brilliant and memorable. … Martin Aigner and Günter Ziegler succeeded admirably in putting together a broad collection of theorems … that would undoubtedly be in the Book of Erdős. … The approach is refreshingly straightforward, all the necessary results from analysis being summarised in boxes, and a short appendix discusses the importance of the zeta-function in number theory. Indeed I have recommended the book to talented undergraduates and to mathematically literate friends. … Martin Aigner and Günter Ziegler succeeded admirably in putting together a broad collection of theorems … that would undoubtedly be in the Book of Erdős. (Gerry Leversha, The Mathematical Gazette, March, 2005)Every finite division ring is a fieldThree famous theorems on finite sets“This book is the fourth edition of Aigner and Ziegler’s attempt to find proofs that Erdos would find appealing. there is enough new material that libraries certainly should do so.

The style is clear and entertaining and the proofs are brilliant and memorable. The theorems are so fundamental … that every mathematician, regardless of speciality, can benefit from reading this book.” (Miklós Bóna, SIGACT News, Vol. During a lecture in 1985, Erdős said, "You don't have to believe in God, but you should believe in The Book." Each chapter is largely independent; some include necessary background as an appendix. Each chapter is largely independent; some include necessary background as an appendix. … I love the fact that the chapters are relatively short and self-contained. He said that there was a book somewhere, possibly in heaven, and that book contained the nicest and most elucidating proof of every theorem in mathematics. … The key to the approachability of Proofs lies not so much in the accessibility of its mathematics, however, as in the rewards it offers: elegant proofs of interesting results, which don’t leave the reader feeling cheated or disappointed."

This revised and enlarged fourth edition of "Proofs from THE BOOK" features five new chapters, which treat classical results such as the "Fundamental Theorem of Algebra", problems about tilings, but also quite recent proofs, for example of the Kneser conjecture in graph theory.
