What did Leonardo da Vinci invent?

There are many mechanical devices designed by Leonardo da Vinci, such as airplanes, parachutes, chariots, all kinds of artillery, diving suits, civil machinery, cars, bicycles and so on.

Leonardo da Vinci's scientific inventions are on display in Vienna. At the exhibition, people can see 62 models and miniature models with the same size as the original objects invented by Leonardo da Vinci. This exhibition is the largest of its kind in the world.

The exhibition "Da Vinci, Man, Inventor and Genius" will be held in Vienna Art Center until May 29th. The design of the most talented genius of the Renaissance includes the "ancestor" of bicycles, divers' respirators, hang gliders, elevators, parachutes, cogged gears, transmission devices, military tanks and other warships or planes, and a ladder for attacking enemy walls. This ladder looks very similar to the ladder used by modern firefighters.

Nicolai Gabriel, an Italian cabinet manufacturer and mechanic, said: "Computer graphics technology has been able to discover the information hidden in Leonardo da Vinci's massive technical drawings, which makes it possible for us to make them work through computer simulation." These models are made of wood, metal and cloth, all made by Gabriel and his colleagues after studying Leonardo da Vinci's design sketches. Leonardo da Vinci's sketches are accompanied by thousands of pages of handwritten instructions explaining how these inventions work.

This heritage at least far exceeds the existing 17 designs left by Italian artists in quantity. Leonardo da Vinci's most famous work is the Mona Lisa. Gabriel and his colleague Paolo Daciani designed several working models invented by Leonardo da Vinci, and said that they have been approved by the scholar Carlo Pedrae Di. Pedre Di is one of the world-famous Da Vinci experts.

According to the organizer, this exhibition is the most comprehensive of its kind, with more models on display than any museum in Italy. Some of Leonardo da Vinci's inventions have been put into practice in his life, such as dredgers to clean up the silt in canals near Milan and moving river bridges with wheels. Other inventions were later put into practice. For example, Napoleon's bomb was modeled after Leonardo da Vinci's design.

But most of Da Vinci's inventions are "wasting time" on the drawing board. A hull with a sealed compartment to prevent a ship from sinking is a typical example. Gabriel said that this hull may be Leonardo da Vinci's most important invention. Double hulls have now become the standard for manufacturing oil tankers. Leonardo da Vinci's bike is very curious. It may have been designed by his students after Leonardo da Vinci put forward his idea. At that time, this kind of bicycle had a transmission chain that moved between the pedal and the rear wheel, but the early bicycles that appeared in the late19th century did not have this design.

Leonardo da Vinci's famous plane was designed on the basis of his long-term study of the working principle of bird wings. The invention of genius sometimes hides great danger. In an experiment, a plane crashed and almost killed one of Leonardo da Vinci's servants. But in modern times, people have successfully flown planes in the sky, such as the giant pyramid parachute successfully tested in Canada. Leonardo da vinci also designed flying tools, such as anemometers and gyroscopes.

When talking about Dan Brown's best-selling book The Da Vinci Code, gabriel compared all kinds of secrets. The book The Da Vinci Code says that Da Vinci likes to hide secrets in his paintings, such as the Last Supper and some details of his technical sketches. It goes without saying that these details are designed to prevent Leonardo da Vinci's discovery from being misused centuries before the birth of the concepts of patents and copyrights.

Gabriel said: "The only original work designed by Leonardo da Vinci that is still in use today is the sluice near Milan. But unfortunately, the authorities did not protect it as a memorial, and now cracks are beginning to appear. " This exhibition is mainly aimed at primary and secondary school students, and its display method may not even be imagined by the futurist artist Leonardo da Vinci. A sponsor also provided a mobile phone, on which visitors can watch the video invented by Leonardo da Vinci. (
