ierre Berloquin, "The Garden of the Sphinx: 150 Challenging and Instructive Puzzles"

EBook Description: These mathematical puzzles have appeared in the newspaper Le Monde during the past few years. A number of readers have responded to the challenge by offering not only original solu- tions and modes of attack but also by stating new problems related to those proposed. A dialogue was thus initiated in which my problems or those I reproduced from the literature generated a new set by stimulating the minds of my corre- spondents. This book presents a collection resulting from the fruitful exchange.

Mathematical Puzzles, for Beginners and Enthusiasts Book

over Publications | 1954 | ISBN: 0486201988 | 248 pages | Djvu | 2,3 MB
Summary: Approachable, engaging, challenging puzzles
Rating: 5
This is a delightful collection of head-scratchers all described in an easy-going format. Puzzles (all of them are word puzzles, and all answers appear at the back) are grouped as algebraic, geometric, easy-arithmetical, combinatoric, puzzles about integers, etc.; none are trivial, some are extremely challenging, and they all teach some point about inference or mathematical method. In the preface, the author writes, "Some of these puzzles are old favorites... to solve many of the puzzles, you need no knowledge of mathematics other than simple arithmetic... the full method of solution is explained for the more difficult puzzles."
Great, great, great for taking an entertaining tour in mathematics and gaining some problem-solving wisdom along the way. When you solve any of these, you'll really feel ingenious. Thank you, Mr. Mott-Smith!
Summary: First-rate
Rating: 5
This is a first-rate collection of mathematical puzzles, from the very easy to the quite difficult. The book is divided into chapters, which usually begin with some discussion of techniques for solving a particular class of puzzles. It stays away from the super-difficult category. As such this book is for nearly everyone, not just those who want to prove their puzzle-solving skill.

Elizabeth Bennet, Betsey Trotwood, Count Dracula, Anna Karenina, Alice and many more come under the spotlight in John Sutherland's highly entertaining collection. Bringing good humor and good sense back to literary criticism, Who Betrays Elizabeth Bennet? offers scintillating forensic exercises that are as compelling as the plots they dissect.
