Puzzlers' Tribute : A Feast for the Mind, Hardcover by Wolfe, David (EDT); Rodgers, Tom (EDT), ISBN 1568811217, ISBN-13 9781568811215, Brand New, Free shipping in the US The door to enlightenment is bewilderment, and the key is paradox. Such is the mantra of the latest collection of essays, some 80 of them, presented at the second through fourth irregular conclaves, Gathering for Gardner, at which mathematicians, magicians, and puzzlists honor Martin Gardner, their high priest. Much of the material is anecdotal about their craft, but of course many puzzles find their way in, not all of which require mathematical or logical adeptness. Each includes a bibliography, but there is no index. Annotation c. Book News, Inc., Portland, OR ()
