Excellent, easy-to-read book for everyone with an interest in mathematics
Two top researchers have made a big effort and selected a list of mathematical problems which can be solved by elegant, esthetically pleasing proofs
Fun for everybody with an interest in mathematics requiring only very little previous knowledge
Third edition offers two new chapters (on partition identities, and on card shuffling). Three proofs of Euler's most famous infinite series appear in a separate chapter. There are also a number of other improvements, such as an exciting new way to “enumerate the rationals”
Has now been published in seven languages, two more editions are in preparation
From the Reviews
"... 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. There is vast wealth within its pages, one gem after another. Some of the proofs are classics, but many are new and brilliant proofs of classical results. ...Aigner and Ziegler... write: "... all we offer is the examples that we have selected, hoping that our readers will share our enthusiasm about brilliant ideas, clever insights and wonderful observations." I do. ... " Notices of the AMS, August 1999
"... This book is a pleasure to hold and to look at: ample margins, nice photos, instructive pictures, and beautiful drawings ... It is a pleasure to read as well: the style is clear and entertaining, the level is close to elementary, the necessary background is given separately, and the proofs are brilliant. Moreover, the exposition makes them transparent. ..."
