A collection of facts and figures complimented with hundreds of illustrations. "Did You Know?" answers questions from whether fish need sleep and who invented the yo-yo to how fast an earthquake travels. It provides facts about people - like Barbara Cartland, who at her most prolific was producing novels at the rate of one a fortnight. A book to dip in to or read from cover to cover, this book covers the whole spectrum of human knowledge and speculation in ten sections - cities and civilizations, wildlife, the frontiers of knowledge, travel, inventions, the skies, famous people, the mind and body and much more.
