Choice Review

A Mathematical Medley is Laubach's offering of mathematical tidbits accumulated during his career as a mathematics teacher. He seeks to share with others selected surprises and thrills he experienced during his career in mathematics. About 20 problems are solved, from determining the speed of a toy gyroscope to terrestrial measurements to tips for mental arithmetic. Fortunately, these are not the typical overworked problems from pure mathematics found in recreational mathematics books, but rather the investigation of more practical issues. The exposition is spunky, with humor retained rather than excised. The book is for those who have math-science-engineering bents. Bookstores with a scientific clientele and larger public libraries with a sophisticated readership may want to make this book available. All levels. W. R. Lee; Iowa State University
