Product Description

In 1781, Thomas Paine came up with a model for a single-span bridge; in 1887, Adolf Eugen Fick made the first pair of contact lenses; and in 1907, Paul Cornu built the first helicopter. But Leonardo da Vinci thought of all these ideas more than five hundred years ago!

At once an artist, inventor, engineer, and scientist, da Vinci wrote and drew detailed descriptions of what would later become hang gliders, automobiles, robots, and much more. Gene Barretta cleverly shows how Leonardo's ideasmany inspired by his love of natureforeshadowed modern inventions, offering a window into the future.
