"Geokinetic instrument, what is geokinetic instrument?"

Some students asked again.

No way.

Regarding the technology of the Eastern Han Dynasty, there are really some subversions of their cognition.

The armillary sphere was before, and now there is another geokinetic sphere.

"A geokinetic instrument is an instrument that monitors the occurrence of earthquakes."

Although the explanation is short.

But Chen Fan just said it, and everyone was wow.

"Monitor earthquakes."

"I'm grass, this is too sci-fi."

"More than 2,000 years ago, I thought of monitoring earthquakes, and it was really black technology."

What's the most unpredictable thing about the world?

That's an earthquake.

Earthquakes are not like weather.

Weather forecasting satellites can go directly to the sky, so weather forecasts are more accurate in many cases.

But earthquakes are different.

Earthquakes cannot be drilled underground because of the instruments, and even if they can drill underground, they do not know much about the occurrence of earthquakes and other causes.

So basically, there is no machine in the world that can predict earthquakes.

Just like in the previous life, many people complained about the relevant units.

Whether there is an earthquake or not, you have to be shocked to know.

You don't know until the earthquake is so big.

If there is no earthquake, then how can you know?

So.

Earthquake prediction has always been a problem all over the world.

But.

Chen Fan threw out a geodynamic instrument at this time.

This made everyone extremely excited.

on this.

Chen Fan explained: "Don't get excited, first of all, the geodynamic instrument is not an earthquake prediction machine. So far, there is no machine or other machine in the world that can accurately predict earthquakes. The geodynamic instrument is a tool for monitoring earthquakes. To put it simply, when an earthquake occurs, he can tell the technician where the earthquake has occurred. ”

Although prediction is not the same thing as monitoring.

But in fact.

Monitoring also has a huge impact.

Just like now.

Even if we can't predict an earthquake, after an earthquake occurs, our monitoring can still tell you in the shortest time.

For example, tell the residents directly through television.

This also reduces damage due to earthquakes.

And through the way of television signals, his speed is often faster than the speed of earthquake propagation.

This has played a tremendous role in alleviating people's lives, health, and property.

This was placed in ancient times, and it was even more reused.

In ancient times, transportation and communication were underdeveloped.

Often, a message from one place to a certain place needs to be transmitted, and it can take a day or two to even travel for several months.

Just like the Western Regions reporting to Chang'an or Luoyang, it will not take more than a month.

If there really was an earthquake somewhere, the imperial court would have no way to communicate in this way.

But if there is a monitoring instrument such as a ground motion instrument, it is different.

"Look, this is a restored version of the geodynamic instrument."

Chen Fan opened the PPT, and then said: "The geodynamic instrument has eight directions, they are east, south, west, north, southeast, southwest, northeast, northwest, each direction has a dragon head with a dragon ball in its mouth, and there is a toad corresponding to it under each dragon's head." If an earthquake occurs on either side, the dragon ball contained in the dragon's mouth in that direction will fall into the toad's mouth, and the direction of the earthquake can be measured. ”

"This geodynamic instrument was made by Zhang Heng. At that time, Zhang Heng lived in the Eastern Han Dynasty of the Han Dynasty, and earthquakes were more frequent. According to the Book of the Later Han Dynasty and the Five Elements Chronicles, a total of 26 major earthquakes occurred in the more than 30 years from the fourth year of Emperor Yongyuan of the Han Dynasty to the fourth year of Emperor Yanguang of An. Earthquake areas are sometimes as large as dozens of counties, causing ground cracks and landslides, collapsed houses, and flooded rivers, causing huge damage. Zhang Heng has a lot of personal experience with earthquakes. In order to grasp the seismic dynamics of the country, after years of research, he finally invented the wind and ground motion instrument in the first year of Yangjia. ”

"In the eleventh month of the third year of Emperor Yangjia of Hanshun, a dragon machine of the geodynamic instrument suddenly started, spit out a copper ball, and fell into the mouth of the toad. At that time, the people in Kyoto did not feel the slightest sign of the earthquake, so some people began to talk about it, and strangely the movement did not work. A few days later, someone in Longxi came to report and confirmed that there was indeed an earthquake there a few days ago......"

So.

Logically, a geodynamic instrument is an instrument for monitoring earthquakes, and it is not predicted.

But.

Even if it was a monitoring instrument, everyone was dumbfounded.

"It's amazing that there was such an instrument more than 2,000 years ago."

"It seems that there are such instruments in the West, all more than 1,000 years later."

"Even if it's unpredictable, it's awesome to just monitor. After all, transportation was not very developed in ancient times, and with this instrument, it would be much more convenient. ”

"It doesn't seem to be useful, he just explained the direction, and he didn't say where there was an earthquake."

"Of course, one geodynamic machine doesn't have much effect, but if you use a few more, or one for each area. In this way, when these machines emit positions at the same time, it is much more precise. ”

"Oh, too."

"So, in fact, our ancient technology is not bad, but it's a pity that no one inherits it."

This is really no one inherited.

Chen Fan also said with some regret: "The geodynamic instrument you see above is not the real geokinetic instrument, and the specific real geokinetic instrument is now lost." This appearance is only restored according to the records in the history books. ”

Speaking of this, Chen Fan was even more emotional.

In the previous life, the original geodynamic instrument was entered into the Chinese textbook, which also let everyone know that there was a person named Zhang Heng in the Eastern Han Dynasty who made the geokinetic instrument.

Later, however, he was deleted from the textbook.

As for the reason, it is that many people question the uselessness of this geodynamic instrument.

In fact, it's not that the geodynamic instrument is useless, but that the restored version of the geokinetic instrument is useless.

Because the real geodynamic instrument is lost.

The geodynamic instrument we see is only restored in the 50s of the previous life according to the principle of Professor Wang Zhenyi.

Compared with the real instrument, the restoration is naturally 108,000 miles away.

But if we only say that the restored geodynamic instrument is useless, and then suspect that the real geodynamic instrument is useless, then this is too lacking in scientific spirit.

In fact.

After Zhang Heng made the instrument, the Book of the Later Han Dynasty, the Book of the Later Han Dynasty, the Book of the Continuation of the Han Dynasty, and the three important historical documents of the previous life have all recorded the geodynamic instrument. Moreover, there are people in the Jin Dynasty who have drawn the structural design drawings of the geodynamic instrument, but because of the age, these design drawings have also been lost. Until 2000 years later, we only knew about the geodynamic instrument, but we never understood what the geokinetic instrument really looked like.

I have to say that this is a huge pity.

……

"After the Eastern Han Dynasty and the Emperor of the Han Dynasty, although there were not several wise emperors, and there were not too many major events in the whole country, the strength of the Eastern Han Dynasty was still very strong. This strength is not only reflected in people's lives, nor only in scientific and technological inventions, but also in medicine. ”

If Zhang Heng's armillary sphere and geokinetic sphere may not have much effect on modern times.

So.

The medicine inherited from the Eastern Han Dynasty had too great an impact on China.

"At the end of the Eastern Han Dynasty, there was a doctor named Hua Tuo. Yes, this Hua Tuo is the Hua Tuo who once healed Guan Yu. Hua Tuo traveled abroad to study when he was young, and practiced medicine in AH, Henan, Shandong, Jiangsu and other places, studying medical skills rather than seeking a career. He had comprehensive medical skills and was called this miracle doctor by the people at the time. Once, there were two military officials, both with fever and headache, the symptoms were the same, but Hua Tuo's prescription was very different, one with diaphoretic medicine, the other with laxative medicine, the two of them were quite strange, but after taking the medicine, they were cured. It turned out that after Hua Tuo's diagnosis, it was known that one was a symptom, which could be solved by sweating; One is the heat syndrome, which is difficult to treat without diarrhea. Ni Xun, an official of Hua Tuo's government, has a headache and a hot body, so he will go down to it, and he will be real with it. If Li Yan is treated with headache and body heat, he will sweat, and his inner reality will also ......"

If you want to say that among the ancient miracle doctors, Hua Tuo is a person who cannot be mentioned.

And.

Because Chen Fan had talked about the Three Kingdoms before, as soon as Hua Tuo in the Three Kingdoms came out, everyone became interested in it instantly.

Not only that, Hua Tuo is also good at psychotherapy. There was a county guard who was seriously ill, and Hua Tuo went to see him. The county guard asked Hua Tuo to treat him, and Hua Tuo said to the son of the county guard: Your father's illness is different from ordinary diseases, there is blood in his abdomen, you should provoke him to let him vomit out the blood, so that he can cure his disease, otherwise he will die. Can you tell me all the wrong things your father has done? I sent a message against him. The son of the county keeper said, "If you can cure your father's illness, what can you not say?" So, he told Hua Tuo all the unreasonable things his father had done for a long time. Hua Tuo wrote a letter denouncing the county guard, and after reading the letter, the county guard was furious and sent a catcher to arrest Hua Tuo, but he was not caught, and the county guard was furious, and spit out more than a liter of black blood, and his illness was cured. ”

"This is psychotherapy, but Hua Tuo also knows more about health. Hua Tuo believes that life lies in exercise, and if you can maintain a good body, you will not get any serious diseases. And he also understands that it is not a doctor who can cure all the diseases in this world. To this end, he imitated the movements of five animals and created a set of "Five Fowl Plays". Hua Tuo said that as long as you practice the Five Birds Opera once a day, not to mention how old you can live, at least it can give you a healthy body while you are alive. ”

Some such magical cases have also opened everyone's eyes.

"Dialectical therapy, psychotherapy, five fowl play...... This concept of medicine is not much different from modern times. ”

"Therefore, the wisdom of the ancients is definitely not worse than our modern ones, and some even surpass them."

"But there is no such miracle doctor in modern times."

But.

About Hua Tuo's medicine, that's not all.

Chen Fan continued: "Hua Tuo is not only good at various diseases, but also good at surgery. ”

"Surgery?"

At this time, a student in the audience raised his hand and replied: "Teacher Chen Fan, is the surgery you are talking about orthopedics?" ”

"Osteopathy is just a general surgical procedure."

Chen Fan shook his head and said: "Hua Tuo is not only a bone correction, but he is even more powerful in surgery." Yes, that is, like modern Western medicine, he used open surgery. For example, when scraping Guan Yu's bones, this is a surgical method. At that time, Guan Yu did not take any protective measures, so Hua Tuo went under the knife directly. But in fact, Hua Tuo invented an anesthetic drug called "Ma Boiling San". This anesthetic can relieve the patient's pain during the surgery. It is precisely because of the creation of hemp boiling that Hua Tuo's surgery is a step further. Hua Tuo's original surgery was only on trauma, but later, after he invented Ma Boiling San, he was able to perform laparotomy surgery......

When Chen Fan told Hua Tuo's medical legend, everyone was already dumbfounded.

Chen Fan continued: "Everyone knows that in the Three Kingdoms, I said that Hua Tuo had treated Guan Yu. In fact, Hua Tuo also treated Cao Cao's illness. Because Cao Cao had had a headache for many years, he heard about Hua Tuo's name, so he summoned Hua Tuo to treat him. After Hua Tuo came, he gave Cao Cao acupuncture treatment, and soon Cao Cao's headache was cured. But Hua Tuo said to Cao Cao, your headache is caused by a long-term illness, and my cure now can only make you feel at ease for a few days, but your head will hurt after a while. If you want to really cure this headache, you have to start with a surgical operation in the head. ”

Cao Cao said, using a knife in the head, whether this Hua Tuo wanted to treat himself or take the opportunity to kill himself. Subsequently, Cao Cao locked up Hua Tuo. When he was dying, Hua Tuo spent his life in prison to create a work called "The Book of Green Bags". After the creation was over, Hua Tuo lamented that he was locked in prison and could not get out. So he said to the jailer, "You have taken good care of me during this time, and I have nothing for you, so I will pass on this medical book to you." But the jailer was afraid and did not dare to take it. Helplessly, Hua Tuo burned the green bag book he wrote......"

There are multiple versions of how Hua Tuo was locked up by Cao Cao.

One version is that it is said to cut Cao Cao.

Another version says that Hua Tuo didn't want to treat Cao Cao, and then Cao Cao was angry and locked Hua Tuo up.

But no matter which version it is, in the end, Hua Tuo was locked up by Cao Cao.

Moreover, he died at the hands of Cao Cao.

Not just died at the hands of Cao Cao.

The most regrettable thing is that Hua Tuo did not pass down his medical works until his death.

When Chen Fan finished telling Hua Tuo's story, everyone only felt addicted to pain.

"Oh my God, a fire has burned."

"Ahh

"Yes, hateful, we have a lot of knowledge, technology, and medicine in ancient times...... It's all lost. ”

"This damn Cao Cao, I hate Cao Cao now."

The crowd was extremely depressed.

……

"It's a shame indeed."

Chen Fan was also helpless.

Hua Tuo can be said to be the most famous miracle doctor in medicine.

But......

Not a trace of his medicine has been handed down.

But.

In addition to the power of the Eastern Han Dynasty, it is not only Hua Tuo.

Chen Fan continued: "In fact, in the Eastern Han Dynasty, not only Hua Tuo was outstanding in the field of medicine, but also a miracle doctor was also very powerful. This miracle doctor, his name is Zhang Zhongjing. ”

In terms of fame, Zhang Zhongjing's fame may be slightly inferior to Hua Tuo.

But when it comes to contributions, Zhang Zhongjing's contribution is far more than that of Yu Huatuo.

Even.

Zhang Zhongjing can be said to have made the greatest contribution to the clinical field of Chinese medicine.

Then, Chen Fan talked about Zhang Zhongjing's life: "Zhang Zhongjing and Hua Tuo were born in the same era, both in the late Eastern Han Dynasty. However, the end of the Eastern Han Dynasty was no longer the early years of the Eastern Han Dynasty, let alone the heyday of the Eastern Han Dynasty. At the end of the Eastern Han Dynasty, various princes competed for hegemony, and the whole country was often in war. Not only that, but there were also many plagues in the late Eastern Han Dynasty. Most of the original tens of millions of people were killed and injured because of wars and plagues. ”

"The original Zhang Zhongjing was born in a family of eunuchs, although he is not as good as those wealthy families, but he has not had to worry about food and clothing since he was a child, and according to normal words, he will also be an official in the future. But Zhang Zhongjing has liked medicine since he was a child, and since he was a child, he has watched countless people die because of illness, which touched Zhang Zhongjing even more, and then he threw himself into studying medicine. ”

After a long period of hard work and his own talent, Zhang Zhongjing soon made a name for himself and became a well-known doctor. Even, Hua Tuo at that time also visited Zhang Zhongjing. When he saw Zhang Zhongjing's medical skills, Hua Tuo, whose eyes were above the top, was also very admired. However, because of the family relationship, although Zhang Zhongjing, who did not want to be an official, was arranged by his family to become an official, and finally achieved the position of Changsha Taishou. ”

"Originally, in the officialdom at that time, generally speaking, if you want to be an official, then don't be a doctor. If you want to be a doctor, then don't be an official. However, Zhang Zhongjing, who has been a doctor since elementary school, can't bear to see the people suffering from illness, but he no longer cares about the rules in the officialdom. He said to the outside world that on the first and fifteenth day of each month, he would temporarily stop dealing with the work in the officialdom and go to the yamen to sit in the hall for treatment. I don't know how many people have been treated through his hands. ”

If Hua Tuo's story has some legends.

But in fact, there are many stories in his legend that may not be true.

Then Zhang Zhongjing, that is, there have been countless historical records in history.

It's just that when people reach the age of 50, Zhang Zhongjing suddenly thought. No matter how high your medical skills are and how good your level is, there are only a few people who can be treated. However, there are so many people in the world, and so many people in the world are sick, how can we cure these sick people by ourselves? For this reason, Zhang Zhongjing thought about it for a long time, and he decided to write a book about his more than 50 years of medical experience and ideas. ”

"Because at that time, the people were the most sick, and that was typhoid fever. Therefore, he put most of his experience and ideas on typhoid fever, so he wrote the treatise on typhoid fever. However, after writing "Treatise on Typhoid Fever", there are many other difficult and miscellaneous diseases. Therefore, on the basis of the theory of typhoid fever, he added the theory of miscellaneous diseases. As a result, one of the most important clinical masterpieces in the history of Chinese medicine, "Treatise on Typhoid Fever and Miscellaneous Diseases", appeared. ”

What is the significance of this book?

Arguably.

Without him, it is estimated that Chinese medicine would have disappeared.

Yes.

Before Zhang Zhongjing, although there were also many works of traditional Chinese medicine, these works of traditional Chinese medicine were all theoretical works.

He doesn't really instruct you on how to treat the disease clinically.

As for why someone would treat, that is, the master takes the apprentice, and slowly the master keeps handing it over to you.

But Master doesn't necessarily teach you everything.

A lot of some content, if the master doesn't teach, it will slowly be lost.

"Treatise on Typhoid Fever and Miscellaneous Diseases" is a work that completely guides the clinical study of Chinese medicine.

As long as you learn the theory of Chinese medicine, and then look at the theory of typhoid fever and miscellaneous diseases, then, with the passage of time, your medical level will gradually improve.

So.

This work is also known as one of the four masterpieces of traditional Chinese medicine.

As for the power of the famous book, how powerful is it?

Just like some modern diseases, one of the most famous Chinese medicines, Lotus Qingwen...... It's the recipe recorded in this book.

It is precisely because of Zhang Zhongjing's contribution to the clinical science of traditional Chinese medicine that later generations also called Zhang Zhongjing a medical saint!!
