Leonardo da Vinci had a fine grasp and understanding of engineering, demonstrated by the many machines he designed. The technology available to him may have prevented successful construction, but there is no doubt about the practicality, these machines could have been made to work.
Not just for children! Scientists and engineers study and learn from Leonardo Da Vinci even today. These kits allow machines to be recreated in 3D, bringing new insight into the ground breaking creativity of a true genius and the world of technology her foresaw.
