This small but mighty collection will trigger your memory with fun facts you learned in school-from adverbs to the Pythagorean Theorem. Witty, engaging, entertaining-a book you'll pick up again and again. Author Caroline Taggart discovered two things while researching this book and talking with other people: One, everybody had been to school. And two, they had all forgotten entirely different things. Contained in this handy little book are the facts that you learned in school, but may not remember completely or accurately. Covering a variety of subjects, this book features all the most important theories, equations, phrases, and rules we were all taught years ago. Rediscover: * History: The first president to occupy the White House was John Adams in 1800 * Religion: The seven deadly sins and the names of the twelve apostles * Literature: In which Shakespearean play "The quality of mercy" speech appears * Science: The periodic table of elements devised by a Russian chemist in 1889 includes the symbol for lead (Pb), silver (Ag), tin (Sn), and gold (Au) * Nature: How photosynthesis works The information-presented in easy-to-retain, bite-sized chunks-is accurate and up-to- date. It will touch a chord with anyone old enough to have forgotten half of what they learned at school. Here is a perfect gift for every perennial student.
