This book presents a new perspective on creativity: that creative innovation depends on inside-of-the-box thinking. It shows that creativity builds on what we know and how we use old ideas to produce new ones. In a highly readable format, Robert W. Weisberg uses case studies of seminal creative advances, such as Leonardo's 'Aerial Screw' and Frank Lloyd Wright's award-winning house, 'Fallingwater.' These fascinating examples are evaluated alongside cutting-edge research to present an analysis of creativity that challenges us to think differently about this intriguing cognitive ability.
