Buzz: The Science and Lore of Alcohol and Caffeine

Whether they prefer scotch on the rocks or a double mocha latte, readers will enjoy Braun's dissection of caffeine, alcohol and the processes by which they work. For one thing, the presentation of complicated scientific concepts is understandable without being condescending. Braun makes analogies (""Drinking caffeine is thus like putting a block of wood under one of the brain's primary brake pedals"") that help the reader to visualize what's going on. The book is also helped by the author's inclusion of stories and humorous moments. From David Letterman quotes (""If it weren't for the caffeine, I'd have no identifiable personality whatsoever"") to personal anecdotes about the effects these two mood-altering substances had upon the formulation of his book, Braun manages to take abstract concepts and mold them into something highly readable. Science novices should find this book as enjoyable and well-written as those who have spent their lives working with biology or chemistry. (Aug.)
