Leonardo da Vinci. Titan of the Renaissance. Painter, sculptor, architect. And also a natural scientist, mechanic, engineer, mathematician. He made many discoveries and foresaw the paths of intellectual searches of subsequent generations. His name is shrouded in an aura of mystery. An innovative artist, Leonardo posed and solved problems that were considered impossible. There was not a single scientific problem that he did not pay attention to. Da Vinci left more than seven thousand manuscripts. These records still excite the imagination of inquisitive researchers. For “he who is not directed towards the stars does not turn around.”
