BRAINS AND REALITY YES VINCI
The great Leonardo da Vinci came up with a lot of devices and devices that we use in our time. For example, a diving suit for divers after pearls. The main thing in it was the "breathing vest", which was very dense and even covered the mouth of a diver. For ballast, two bags of sand were used.
Another invention of Leonardo & mdash; a boat with a drive, was equipped with propellers with blades. It was set in motion not only with the help of hands, but also the feet, which accelerated the movement at times, compared to manual rowing. The body was made in the form of a fish, since the genius considered it to be the most harmonious in this environment. Thus, Leonardo solved the problem of navigation and acceleration when moving in an aquatic environment.
