Leonardo Da Vinci made some important contribution in both science and art. As an engineer, Leonardo conceived ideas vastly ahead of his own time, conceptually inventing the parachute, an improved version of the helicopter, an armored fighting vehicle, the use of concentrated solar power, a calculator, a rudimentary theory of plate tectonics and the double hull. In practice, he greatly advanced the state of knowledge in the fields of anatomy, astronomy, civil engineering, optics, and the study of water (hydrodynamics).

Leonardo's most famous drawing, the Vitruvian Man, is a study of the proportions of the human body, linking art and science in a single work that has come to represent Renaissance Humanism.
