Top 5 most populous megacities worldwide
The United Nations has released fresh data on the most populous cities in the world. Let's take a look at the top megacities by population.
The greatest inventions of the brilliant Leonardo da Vinci, who lived in the far 15th century, determined the progress in science and technology for many centuries to come. He was one of those who was ahead of his time. This is eloquently evidenced by the creations of the famous master. We suggest you familiarize yourself with the most popular ones.
Mechanical Knight
After carefully studying the human anatomy, Leonardo da Vinci developed the first robotic humanoid. During the work, the master found out that the muscles and joints move the bone apparatus, and this concept formed the basis for creating a robotic machine. For some time, the robot-knight existed entertaining the rich at local parties. He could clamp his jaws, walk and sit. The entire robotic system was operated by a series of pulleys and cables.
Airscrew
An airscrew is one of the amazing inventions of da Vinci. It was like an aircraft, a massive pinwheel acting on the principle of a helicopter. With rapid untwisting, the plant elements provided the necessary aerodynamic properties and traction to lift the machine up. The air cushion produced pressure under each blade.
Megapolis of the future
Earlier, when the epidemic of plague raged in cities, da Vinci wondered whether it was possible to design and build a "clean" city from scratch. According to the scientist, the terrain must be divided into several levels. They can be provided with minimum sanitary standards. In the metropolis, there are channels for removing sewage. With the help of a hydraulic device, each dwelling should receive water. However, the authorities did not allocate funds for the construction of the miracle city.
Armored Tank
The ingenious master also developed an armored tank project. Outwardly it resembled a "tortoise" and housed eight men with 36 guns. Soldiers were protected by an outer shell. The tank consisted of serrated wheels, but the front wheels were rotating in the opposite direction from the rear wheels, which made the movement difficult.
Diving suit
The concept of Leonardo da Vinci on the destruction of enemy ships meant the creation of special diving suits. People could breathe in them using an underwater dome with air. People wore masks with glass niches and were able to see well under the water. Another option of the costume is the use of wine bottles instead of the dome which were filled with air.
Combat Machine Gun
The machine gun developed by the brilliant master differs from modern weapons. For example, muskets fired at short intervals. The mechanism of work is as follows: it was supposed to unite 11 guns on a rectangular plane, and then three planes to assemble into a triangle. In the middle, there was a shaft that allowed to turn the construction. Each set of 11 guns fired while the other two were being recharged.
Parachute
The great master was the first in the realization of the modern rescue device, a parachute. The idea of man's flight all his life pursued the scientist and was embodied in this invention. The device, created from a strong fabric, had a pyramidal shape. In our time, this device was designed exactly according to the scheme of the scientist and confirmed its functional.
Ball Bearing
Many consider da Vinci the author of the idea of creating ball bearings. This device ensures the movement of the drive shafts, and is also used in conveyor and other systems. In the notes of the master, survived to this day, a mock-up of this mechanism with a detailed description is found. If the thinker had enough resources to implement all projects, he could change the world, experts believe.

Deepfake is a technology based on artificial intelligence to create ultra-realistic fake videos, audio, and images featuring real people. In recent years, it has gained incredible popularity, evoking both admiration and concern. Celebrities, whose faces are often used for such purposes, have felt its impact most acutely. In this article, we will discuss five of the most "deepfaked" individuals who have become the main victims of this emerging technology.
The biggest news of recent days has been Donald Trump's victory in the US presidential election. This event has caused a stir around the world, reminding us of the significant role a US president plays in both national development and international affairs. Throughout US history, several presidents have dramatically reshaped the country's domestic landscape and strengthened its influence abroad. Let's take a look at some of the most influential
