"Movement will cease before we are weary of being useful."
Italian polymath Leonardo da Vinci was born #OTD in 1452.
Leonardo's notebooks are perhaps as famous as his artworks, containing sketches, diagrams, and notes on a wide range of subjects. He made significant contributions to anatomy through his detailed anatomical drawings, which were far ahead of his time. He also conducted experiments in various scientific fields, including optics and aerodynamics.
