What is the role of Zhang Heng's geodynamic instrument? Why was it removed from history textbooks? In recent years, the world's ** has happened frequently, and there have been Weibo hot searches and ** shadows, as a person who has grown up in Chinese education, it is not difficult to think of Zhang Heng and his Chi Dongxi when it comes to mentioning**.

That's what the book says. "Cast due east, with a diameter of 8 feet, the lid is raised, shaped like a wine venerable, and decorated with the shape of a turtle and a beast in Wenshan. (William Shakespeare, Hamlet) two weeks in the middle of the road, nearly 8 degrees, the city official erection .......

The book says that if ** happens in a certain direction, the Longkou pillar in that direction will spit out, for the direction and time of ****, it has not been proven, but recently I heard that the section "Jidong" was deleted from the textbook, I don't know why. Let's take a look.

Why was Zhang Heng's ** instrument removed from the textbook?

There is a historical record of the success of the instrument. On that day, the organ in the dragon's mouth was triggered. But no one felt that the ground was shaking, and everyone felt that Brother Zhang had deceived them.

But a few days later, the messenger suddenly wrote a letter saying that a big ** had occurred in the area of Venus and Longxi, more than 1,000 miles away from Luoyang, and the defense and trigger organs were the same. Since then, Zhang Heng has been respected as the first in ancient China.

In fact, as early as 1875, Wang Zhenhao, a historian of ancient science and technology in China, began to restore the appearance of Chi Dongyi. In 1883, the British scientist Mirren also tried to restore geomagnetism. In 1917, the architect Lu Yanzhi also published a restoration drawing.

The "Chi Dongyi" in our textbook is the "restoration map" redesigned by Mr. Wang Zhenhao in 1951, which is the appearance of Chi Dongyi in our childhood memories.

Due to the age, the No. 1 machine invented by Zhang Heng has been lost for a long time. He also did not leave a pattern or a detailed description. Then, the ** instrument ** and the introduction were selected as textbooks.

But later, Li Zhidongjie was very controversial in academic circles. Because it has been tested in practice, it seems that it cannot be used. In the end, the Zhidong model restored by Wang Zhenzhuo in 1951 was judged to be an error in the principle of recovery and was deleted from the textbook.

But the motive restored by Wang Zhenzhuo does not "work properly", but the one more than 1,800 years ago does not mean that it does not "work properly". Our textbooks are constantly being updated, and the content of the textbooks is adjusted when the time comes, so it is normal to find that there are deletions.

As memories of childhood books, we don't want Zhang Heng and Chi Dongxi to disappear from people's field of vision like this. It is hoped that Chinese scientists can use their years of experience and exquisite methods to restore their intellectual motivation as soon as possible. Hopefully he will appear in the textbooks again and shine again. (on the other hand).

For more than 100 years from 1875 to the present, thousands of Chinese and foreign scientists have been painstakingly exploring this geodynamic instrument. More than 1,000 models of geodynamic instruments have been restored, and tens of thousands of experiments have been carried out, but all of them have failed.

In 1972, the Japanese archaeologist Sekino Yu denied it through calculations"There are all pillars"The principle of the upright rod. Sleiswick of the Netherlands and Sevi of the American also proposed that Wang's model could not be established even theoretically.

The British scholar Joseph Needham, who was originally a senior admirer of Zhang Heng, sharply pointed out that the "Wang's geodynamic instrument" did not match the historical records.

In 1984, Academician Usain Bolt, an American scientist, fired directly at the "Wang's geodynamic instrument": "The working principle of this geodynamic instrument model is fuzzy, the model is simple and rough, the mechanical friction greatly reduces the sensitivity, and the response to the first is even lower than the sensitivity of humans, and it is not scientific to determine the epicenter according to the direction of the copper pill."

The geodynamic instrument we saw in the textbook before was restored in 1951 by a person named Wang Zhenduo, according to historical materials, combined with his own imagination. Subsequently, the ** instrument and the introduction text were selected into the textbook. But then this geodynamic instrument was very controversial in the academic circles, because it was tested in practice and seemed to be unusable.

In the end, it was decided that the model of the geodynamic instrument restored by Wang Zhenduo in 1951 was removed from the textbook due to the wrong principle of restoration.

The function of the ground motion instrument is to prevent and provide information for people to prepare for evacuation in advance; However, because its principles and prototypes have not been proven, it has been removed from history textbooks in the spirit of scientific rigor.

This is becauseThe illustration of the weather weather geodynamic instrument in the history textbook is not the geodynamic instrument designed by Zhang Heng, and the real geokinetic instrument has long been lostNo one knows what it really looks like, and the illustration of the geodynamic instrument in the junior high school textbook is a model made by Mr. Wang Zhenduo in 1951, he is an archaeologist, because he has not excavated the real geokinetic instrument, and he regrets it, so he did it according to the description of the history book.

There are many uncertainties and controversies in the history of geokinetic instruments. It is, of course, a good "patriotic" teaching material, butIn line with respect for history, from the perspective of rigor and close to the historical truth, in the first volume of the seventh-grade junior high school history textbook put into use in the fall of 2017, the original content about Zhang Heng and the Houfeng Ground Motion Instrument was deleted from the history textbook by the Ministry of Education.

The geodynamic instrument is a masterpiece created by Zhang Heng, a scientist in the Eastern Han Dynasty of China, in order to grasp the national dynamics, after years of research, the world's first instrument that can be verified appeared, which is the first geodynamic instrument. The geokinetic instrument has eight directions, each of which has a dragon head with a dragon ball in its mouth, and there is a toad below the dragon's head, once the ** occurs in which direction, the small bead in the dragon's mouth will fall into the toad's mouth.

It is reported that when it was first verified, a dragon machine of the geodynamic instrument suddenly started and spit out a copper ball. But Luoyang in the Eastern Han Dynasty did not happen, but people did not feel the omen of **, so some people began to talk about it, blaming the ground movement instrument for not working, but a few days later, the news came in the direction corresponding to the dragon's head, and the direction did happen.

The place where the ** occurred is thousands of miles away from Luoyang, which shows how advanced the geodynamic instrument was at that time. However, there is a big regret that there is no physical proof so far, due to the long history of Zhang Heng's geodynamic instrument has been lost, leaving only more than 100 words of written records. This kind of instrument in China is more than 1,700 years earlier than the history of Western countries with instruments, nearly 1,800 years.

It is not known what the geodynamic instrument looked like 1800 years ago. Many experts at home and abroad try to restore the geodynamic instrument according to the simple description of the "Book of the Later Han Dynasty and the Biography of Zhang Heng", but none of these restoration models can really be used for monitoring, but unfortunately none of them can be verified. Therefore, people have removed history textbooks for the unconfirmed ** instrument of geokinetic instrument.

Because Zhang Heng's geodynamic instrument does not conform to scientific facts, and the degree of restoration is not enough.

So much so that this kind of geodynamic instrument does not have any homework for **** or **, and it may mislead students when placed in the textbook, so it is deleted by the history textbook.

It has not been proven to be actually usable.

**It is a natural disaster that many people are concerned about, some time ago Sichuan ** is heart-wrenching, so many people think** can be like the weather, can be predicted in advance, so that life will be safer and more convenient.

Although the ancient Zhang Heng's invention of the geodynamic instrument has brought us great benefits,However, his ground motion instrument can only detect whether the ground has moved, and cannot detect the specific azimuth of **

Therefore, the authenticity of the geodynamic instrument will also start to be doubted, and then it will be removed from the textbook.

Many scientists know about Zhang Heng's invention of the ground motion instrument, but few will try it.

Eventually, the scientific team developed a modern geokinetic instrument based on historical descriptions.

Although according to the historical description of the remodeling of the geodynamic instrument, but did not detect the ** direction at all, such a result makes scientists feel very difficult, and some people say that the geodynamic instrument also has a name, called the wind geodynamic instrument, it is measured by the wind whether it is **, but such an ambiguous thing, in the authenticity of the beginning to become confusing.

Because the geodynamic instrument invented by Zhang Heng has been lost for more than a thousand years, there has been no physical unearthed, suffering from no physical proof, and the black technology of the geodynamic instrument is too magical, people don't even know its principle, and many people have questioned the authenticity of existence.

Therefore, in line with the attitude of rigorous learning, he reluctantly invited the geodynamic instrument invented by Zhang Heng out of the history textbook temporarily.

Although we have neither the physical excavation of the geodynamic instrument nor the principle of the geodynamic instrument, it does not mean that the geodynamic instrument invented by Zhang Heng does not exist.

After all, there are many things in ancient times that we can't make now.

They said that hanging a piece of meat from the beam of the house was also more effective than this geokinetic instrument. It can also be seen that with the development of science and technology, people have greatly improved some of the previous ancient equipment.

Because he has always maintained a skeptical attitude towards the geokinetic instrument. He thinks that dropping a piece of flesh on a beam can also be stronger than a geokinetic instrument. Because netizens are also very controversial, they were removed from the textbook.

The academician of the Chinese Academy of Sciences said that "a piece of meat on the beam of the house is stronger than him", mainly because of the rapid development of science and technology today, which is a very useful invention for the ancients, but now it seems very chicken, so Zhang Heng's geodynamic instrument has been eliminated.

He said there was a lot of controversy about the item. His response was also very direct. And he doesn't think this instrument is of much value.

His invention was very flawed, and there were some places that would mislead people, and in order not to continue to mislead people, he would remove it from the textbook.

It shows that this statement has been known and understood by many people, and there is no need to set up corresponding courses in this regard, so they will choose to move these out of the textbook, which is also a consideration in this regard.

Academicians of the Chinese Academy of Sciences said that this kind of knowledge is not suitable for appearing in textbooks, and it has no practical use, and there is no scientific basis.

Because this phenomenon is understandable, because the technology is very high nowadays, it is normal for students not to understand these things.

Because the perception of this tool is now changing, we must seek truth from facts and not exaggerate the merits of the ancients.

The academician of the Chinese Academy of Sciences said that although Zhang Heng's geokinetic instrument has been published in the textbook, it is still the pride of our country and should not be forgotten.

The academician of the Chinese Academy of Sciences felt that Zhang Heng's geodynamic instrument was very unworthy of study, and it was also very stupid, which was a complete waste of time.

The Chinese Academy of Sciences said that this is not a fact at all, and it has a particularly strong skeptical significance, and then this situation is not true at all and belongs to pseudoscience.

It means that this is normal, there is a problem with the geodynamic instrument itself, and human wisdom should not be limited to one field, but should be developed in an all-round way.

The academician of the Chinese Academy of Sciences said that he should not actually move his geodynamic instrument out of the textbook, because this can allow students to learn better knowledge.

It certainly makes sense, but the reason for this is still inconclusive. It may be because there is a certain deviation between this history and the real history. It is also possible that there are new theories that overturn the original results.

But there are no definite results yet, and there will definitely be results in the end.

The function of the ground motion instrument. Speaking of this geodynamic instrument, I can still remember the ** used in the introduction of the history book, which is really impressive. I don't think I'll be able to do it in 200 years.

So I didn't become an inventor later, mainly because I was self-aware. The disaster brought by ** is very serious, and Wenchuan ** can see it. This may be the purpose of Zhang Heng's research on it.

At first, few people believed that there was a year, and the geodynamic instrument was monitored, but the people in Luoyang did not feel it, saying that the invention was useless, and a few days later, Longxi, which was very close to Luoyang, came to report, saying that a few days ago, Longxi had a **,Zhang Heng has been famous since then

The real geodynamic device is not necessarily still there. In fact, the geodynamic instrument in the books we see now is what later generations imagined the geokinetic instrument to look like at that time, and then drew it. In fact, the real geodynamic instrument has dissipated with history.

But many of us still regard the appearance of the geodynamic instrument in the textbook as the real geokinetic instrument.

Why delete. This should be a kind of respect for the real history and the invention of the ancients, after all, we don't know what it really looks like, and we can't use our imagination to hide the real thing.

Because the geodynamic instrument was very useful in ancient times, but with the development of technology, it may have some irrationalities.

It may be because of Zhang Heng's geodynamic instrument, he is not able to measure ** to some extent.

It's because this kind of thing actually infringes on the interests of **, so it was deleted.

Because the history books are also changing all the time. So some content will be saved.

Maybe Zhang Heng's geodynamic instrument infringes on the interests of others. So it will be removed from history textbooks.
