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, ingenious approach--a new mode of thinking--linked highly diverse areas of inquiry in startlingly original ways, ushering in a whole new era. In Leonardo's Legacy, award-winning science journalist Stefan Klein provides "an illuminating new look at Leonardo's unique genius" ( Publishers Weekly), which delves into the brilliant, complex mind of this quintessential Renaissance man.
