One of Da Vinci's most famous scientific pursuits was flight. He designed all sorts of flying machines, including the ornithopter, which was basically a flappy-winged contraption that unfortunately never actually flew. But hey, at least he tried, right?
Da Vinci also drew up plans for armored vehicles, submarines, and even robots! Okay, so maybe his robots were just mechanical knights that could sit up and wave their arms, but still, it's pretty cool. I mean, who needs a smartphone when you can have a medieval robot?
And let's not forget about Da Vinci's work on engineering and architecture. He designed all sorts of bridges, canals, and buildings, including a famous self-supporting bridge that was way ahead of its time. This guy was like the MacGyver of the Renaissance!
