We have two mottos here at Portable Press: "Get smart" and "Have fun." As the publishers of the wildly popularUncle John's Bathroom Reader series, we have 20 years' experience in translating our mottos into best-selling books, but we also know that not every reader is a bathroom reader.   That's why we've created this definitive collection of bite-sized bits of knowledge that covers a wide variety of topics ranging from the seemingly ordinary to the obscure.   We'll take you on a fun and fascinating trip through the essentials (and nonessentials) of history, science, geography, the arts, pop culture, language, mathematics, and more. So you can become a genius--instantly!
