Công Nghệ 7.000 Năm Trước, Chịu Được Động Đất Cấp 8 - Ngày Nay Không Thể Sao Chép

7,000 years ago, technology could withstand an earthquake of level 8. Today, it can't be compared to that. I, Duc, would like to greet the audience of Ngam Radio. Today's story is about sophisticated technology from thousands of years ago. And we will start from an experiment 5 years ago. In 2017, an earthquake simulation experiment was carried out with the model of an ancient Chinese building on an earthquake site. Foreign experts say that this fragile ancient building is difficult to withstand an earthquake of 6 Richter degrees. But in front of their eyes, the intensity of the earthquake started from level 4, exceeded level 6, then increased to level 7, level 8. Although the shaking is getting worse, the ancient buildings still stand firm without collapsing. The intensity of the experiment is still increasing. Where is its limit? The strange thing is that the entire building has no steel or iron bars. Everything is connected by a thin frame. It can only withstand a few trees on the ground. It can withstand such a strong earthquake. After a lot of deep research, the ancient Chinese building's intelligence came from 7,000 years ago. Before going into this unbelievable story, please give Ngam Radio a like to support us. In 1979, Vinh Dinh River, Ngoai Thanh, Bac Kinh. At that time, a heavy equipment fleet needed to cross the river. Because of the heavy earthquake, some newly built bridges on this river seemed to be unbearable. Experts have calculated in detail. The next day, there was a proposal to the Ministry of Transport, but it sounded extremely unreliable. Experts believe that it is necessary to hand over this impossible task to the ancient bridge on Vinh Dinh River, no need to reinforce it. This ancient bridge was built more than 800 years ago. Is it okay? Then, 729 tons of heavy equipment was carried up the bridge and the monitoring equipment showed that the bridge was sinking. Everyone was sweating. After 20 minutes, the transfer through the bridge was completed and the ancient bridge was safe and sound. Everyone suspected that this ancient bridge was the famous Lu Bridge. Why is it so powerful? If you want to find out, you need to look back at what happened here more than 800 years ago. In 1189, Lu Bridge. At that time, Vinh Dinh was still a very vast river, it was very difficult to use a stone bridge to cross the river. But the emperor ordered that there must be a convenient bridge for passengers and enough for four carriages to run parallel. Finally, the Governor-General at that time designed Lu Bridge like what we see now, which is a strange narrative. At that time, the Governor-General was very upset how to build a bridge to cross the Vinh Dinh River. When he was concentrating on thinking, he heard an old man selling bamboo outside the alley. Buy bamboo, buy bamboo. The sound of the knife was so loud that he felt uncomfortable. But this is the North, where does the bamboo come from? This one, he told the guards to take a look. After a while, the guards reported that the old man had left, but they found his basket. The Governor-General ran out to see. When he opened it, he saw that it was not bamboo, obviously it was bamboo. It was a wide-headed steel structure in the middle of the alley. Wooden beams are often used to stack wood, and iron beams are used to stack stone. Obviously, the old man was hinting that he used iron beams to connect the stones so that the bridge could stand naturally and withstand earthquakes or floods. Because of careful thinking, where did this old man come from? Or did the Governor-General show up to help him overcome difficulties? The next day, he led all the guards to the temple to pray. Three years later, the bridge was completed. To this day, more than 800 years later, it is still standing on Vinh Dinh River and can carry 429 tons of heavy equipment. This is not because it is strong, but because it is flexible. Because behind these models is a super technology of Taoism. It makes the stones resilient, and also makes the whole bridge soft to overcome stiffness. This is very suitable for the philosophy of Taoism. After that, this inspiration was used by Boeing engineers. Aircraft technology Have you ever wondered why the engine makes a buzzing sound when it is flying? Is it because there are some loose parts inside? In fact, it is true that there are really loose parts, but this is the intention of the engineers. Initially, when the engine was still a fan, if the armor was too rigid, even a little loss of balance would be released during high-speed filming and the propeller could be broken. So how to do it? People say that the first generation of Boeing engineers told their colleagues a story of Taoism about using softness to overcome stiffness. And then, these loose fans are used as sound-resistant parts. When filming at high speed, we cannot balance each fan, we can only follow it, so that each fan has a loose part to restore itself. When filming at high speed, the fan will use the empty space in the foam to fill it up, a fan will repair itself and finally become a perfect circle. In fact, it is just a low-level technology of Taoism, the ancients also had a more advanced core technology. But before introducing this technology, let's take a look at this. 7,000 years of technology In 1973, Chinese archaeologists discovered a foam joint 7,000 years ago in a region in Hà Mỗ Độ, in Chiết Giang province. This discovery attracted great attention because it meant that at least 7,000 years ago, the Chinese had mastered the foam joint technology. Moreover, at the site of the excavation, a large number of bones were found and they were considered to have traces of the joint human being used. Therefore, archaeologists argued that the Hà Mỗ Độ people had developed the foam joint technology based on the biological mechanism 7,000 or 8,000 years ago. This evidence is so strong that the stories about the Egyptian civilization are confused. Their solar energy boat also has a similar foam joint, but obviously their boat is only more than 4,500 years old, while this relic is almost 7,000 years old. Later, the Germans dug a series of ancient European foam joints, which are also 7,000 years old. In addition, in Germany and Northern Europe, there are many ancient wooden buildings. However, in the Vikings, it is considered to be a giant wooden structure that does not use any nails. Thus, wooden foam joints are found all over the world and it is still not clear who started it. In addition to the foam joint structure, the ancient Chinese is actually another core technology that does not seem to have been used by other ancient civilizations. It can be called six-letter building from top to bottom. Does this make you confused? Why did the Chinese build the first building, then built the wall, and finally the window? While we are familiar with the usual way of building, which is to dig a hole first, build the wall, and then install the machine. Just because of this difference, some people say that the ancient Chinese completely did not understand about science, even from a giant foam joint American journalists have met architectural experts from all over the world to ask about this, but no one can reveal the secret about the anti-earth ability of the Forbidden City. So, the journalist decided to investigate First, ask Chinese architects to restore a model of the palace in the laboratory, then imitate an earthquake to see how it could resist the earth. The architects patiently explained how people used to rely on concrete to withstand gravity, then used the foam to build the roof. These theories made foreign experts confused. Before the experiment, they thought that level 6 was almost the limit of the earthquake. After that, the experiment started. In 30 seconds, if the house collapsed, it was the limit of the earthquake. Test level 4, level 4.5, and level 5. When it reached level 5.5, the wall collapsed, but the old building was still intact. When it reached level 7.5, the whole house began to shake, but there was no sign of collapse. The experiment room increased to level 9.5. This is the strongest level of earthquake that people have ever recorded. But after 30 seconds, not even a brick fell. This is hard to believe. The old building did not have this foundation to resist the earthquake. A Chinese expert at the scene pointed to the red line on the roof and said, Brothers, the first trees are crushed into the red line, but now they are frozen. In fact, if you try to bury the trees in the mud, a large earthquake can break them for a long time. But they took advantage of the weight of the roof and caused the pillar to fall on the ground. The moving pillar can reduce the impact of the collapse. And finally, on the roof, which is a concave structure, it has a strong impact and absorbs good vibration. Therefore, we can see the house as a kind of magic in an earthquake. In fact, if we continue to look at the city wall, they are not without shingles, but up to 18 floors, a layer of limestone to a layer of soil. This kind of shingles is like the principle of the railway. The solid layer of limestone can remove a lot of impact of the earthquake. Finally, an old building that is both hard and soft was built. If you look closely at these pillars, you will see that this is the soul of ancient Chinese architecture. Each pillar comes from a deep forest, in which there are giant bamboo trees that have developed for at least hundreds of years. This kind of intelligent and advanced technology with nature is really the heart of the ancient religion. Later, Japan also captured the architecture of these ancient buildings a lot. But when they opened their structure, they would see that they lost the core technology of the lower class. This is an ancient technology that cannot be copied. In Tianjin, China, there is a 16.08-meter-tall monument in the main hall. The ancients decided to use a three-story house structure to allow visitors to experience the experience of this monument from many angles. Therefore, they first laid a layer of limestone on the ground, then covered it with a second layer of limestone, and then put the pillars on top of it. Just like that, they built three floors. It is said that the architect designed it initially from the time of the road, then adjusted it to the time of the house, more than 1,000 years ago. Over the past 1,000 years, the monument has gone through at least 7 major earthquakes with a magnitude of 7.5 Richter. So this three-story structure is still unbreakable. The way the ancients calculated the mechanism of this was a talent. If you want to see something special, there is still a structure in Huyen Ung, Son Tay Province. The Chinese Huyen Ung Wooden Tower, the Pisa Pagoda, and the Eiffel Tower are also called the three most strange towers in the world. Huyen Ung Wooden Tower is a complete structure made entirely of wood, 67 meters high, without a single steel wall. The total amount of wood used is 3,000 cubic meters and weighs more than 2,600 tons. You think it's an architectural tower. In fact, it's a giant manual model. Funnily enough, if a giant could lift this building up and put it somewhere else, it would still be the same. Although there are five floors outside, when you step inside, you will find that it has nine floors. To build it, the ancients designed four low-lying layers to imitate the biological characteristics of the bamboo tree. One layer of space, one layer of bamboo fire. Using this structure to enhance its durability in a miraculous way to resist the strong wind and rain. Huyen Ung Wooden Tower was built in 1956, which is 967 years ago. In the 1920s, Quang Huyen had a strange dream. After waking up, he thought that the Feng Shui of Huyen Ung was not good and he had to do something. So he had people remove some large pieces of wood and replace them with square pieces. Quang Huyen still thought that he had been given by the Buddha to repair a design mistake that lasted 1,000 years. The result was 100 years later, where the trees that were destroyed by Quang Huyen were severely transformed. Although the structure can still resist and there is no sign of collapse at the moment. Maybe you want to ask why no one quickly fixed it? It's not that I don't want to fix it, but I really don't know how to fix it. Ancient technology has been lost for a long time. The repair method has been discussed since the 1990s but there is still no conclusion. Maybe in the end, those who have the high technology of the 21st century can only use steel concrete to restore this beautiful antique manual model. This is a real pity. Let's go back to reality and take a look. It turns out that our culture has been inherited for a long time. 7,000 years ago, the ancients understood that according to nature, they created extraordinary architectural techniques The path of science of our other ancestors has gradually drifted away from nature in architecture, technology and life. If we can return to nature with language and traditional culture, it may be a blessing. What do you think about this? Please leave a comment below.
