A Gardner's Workout

" "[Gardner's writings]are the best explanations of mathematics you can find and it has already been proven that they light a fire of enthusiasm for mathematics." -Charles Ashbacher, Journal of Recreational Mathematics , November 2002 "The effectiveness of this book derives in large part from the passion with which Gardner shares his mathematical enthusiasm and on the breadth of erudition of his discussions. This is another winner!" -Edward J. Barbeau, Crux Mathematicorum , October 2001 "This collection differs from his previous collections in that the articles cover a much wider range than before." -David Singmaster, LMS , January 2003 "... even well-known puzzles retain their power, as was made clear again and again last month at the seventh "Gathering for Gardner." These conferences of mathematicians, puzzlers, game-players and magicians at the Ritz-Carlton here began as personal tributes to Martin Gardner, Scientific American's legendary Mathematical Games columnist, and now take place without the master's presence (he is 91). During four days of talks and tricks, the oldest puzzles mixed freely with the newest." -Edward Rothstein, The New York Times , April 2006 "There are many choice plums among this [collection], some containing a pointer to deeper ideas, some unsolved, and some plain fun, but all entertaining ... I shall enjoy dipping into the book from time to time ..." -The Mathematical Gazette , March 2002 "This is a remarkable book... It will surely produce a paradise for anyone who wants to enjoy teh pleasure of the creative work in his brain." -EMS Newsletter , March 2003"
