Revered today as, perhaps, the greatest of Renaissance painters, Leonardo da Vinci was a scientist at heart. The artist who created the Mona Lisa also designed functioning robots and digital computers, constructed flying machines and built the first heart valve. His intuitive and ingenious approach--a new mode of thinking--linked highly diverse areas of inquiry in startling new ways and ushered in a new era. In Leonardo's Legacy, award-winning science journalist Stefan Klein deciphers the forgotten legacy of this universal genius and persuasively demonstrates that today we have much to learn from Leonardo's way of thinking. Klein sheds light on the mystery behind Leonardo's paintings, takes us through the many facets of his fascination with water, and explains the true significance of his dream of flying. It is a unique glimpse into the complex and brilliant mind of this inventor, scientist, and pioneer of a new world view, with profound consequences for our times.
