Leonardo, the Man Who Saved Science

S16 E5: Leonardo da Vinci is well known for his inventions as well as his art. But new evidence shows that many of his ideas were realized long before he sketched them out in his notebooks — some even 1700 years before him. Of these "inventions," Leonardo never affirmed that his projects came from his original ideas. Leonardo, The Man Who Saved Science features drawings of his most famous ideas and inventions, some of which trace their original creation to ancient Greece while others were a product of the scientific inventions of golden age of Islamic learning. This knowledge seemed to be lost in Europe during the Dark Ages until the Renaissance when Leonardo recovered it.
