Visitors from Oz: The Wild Adventures of Dorothy, the Scarecrow, and the Tin Woodman
In time for the 100th anniversary of the publication of The Wizard of Oz, popular mathematician, pseudo-science debunker, professional literary eccentric and first chairman of the International Wizard of Oz Club Gardner (Classic Brainteasers; The Annotated Casey at the Bat) has cooked up this rather disenchanted bagatelle, mixing fin de (this) siecle satire with references to several childhood classics. As one would expect from the world's premier math puzzle expert, the book contains a little math puzzle. Dorothy, the Scarecrow and the Tin Man want to return to earth for a visit, but how can they get through the fourth dimension that separates Oz from earth?
