The revival of Shu Han

Chapter 344 The Future of the Country ([-])
After getting off the podium, Guan Yi took King Ganling and others to visit two full-time teachers of Longshouyuan College.

One is the famous Huangfu Mi.This master is honored as "the originator of acupuncture and moxibustion" in the field of traditional Chinese medicine.His medical skills are well-deserved number one in this era when Hua Tuo and Zhang Zhongjing have passed away.

As the great-grandson of Huangfu Song, Huangfu Mi is of course a descendant of the family.Fortunately, he is an outlier among the children of the aristocratic family: he is not interested in being an official, but likes medicine and literature.Therefore, after Sima Yan ascended the throne, he repeatedly recruited him to be an official, but he refused to accept it.After Guan Yi briefly described the idea of ​​vaccinia prevention against smallpox in a letter, Huang Fumi came to Chang'an willingly and signed a ten-year contract of prostitution to Longshouyuan Academy.

And the other one, if you're not a math major, it's not surprising that you don't know him.If you are a student majoring in mathematics, then his name is hard to get around: Liu Hui, the author of "Nine Chapters of Arithmetic Notes" and "Sea Island Mathematical Classics", and the founder of the ancient Chinese mathematics system.

General division, approximate division, four arithmetic operations, square root, square root produces irrational numbers, linear equations, methods for calculating the area of ​​various irregular geometric figures, sphere area formula, double difference, circle cutting method to find pi, etc., etc., They are all created by him or summarized into theory by him...

Mathematics is the foundation of all natural sciences.The greatest mathematician of this era, of course, Guan Yi must include him under his command.

It's different from Huangfu Mi, who is a son of a family, who specializes in medicine and literature when he has no worries about food and clothing.Liu Hui was a commoner and lived a very hard life.Therefore, the invitation to Liu Hui was a lot less troublesome than that of Huang Fumi: after Si Wencao brought Guan Yi's letter, promising to hire him with a high salary and unlimited funds to support him in scientific experiments, Liu Hui came happily.

"Your Majesty, gentlemen, this is Mr. Huangfu Jing'an. In Yi's opinion, Mr. Jing'an is the number one doctor in the world."

China, as an official-based society.Officials have always belonged to superiors, and teachers are the second most respected profession under officials.As for the doctor...

Zhu Danxi, a medical master of the later Yuan Dynasty, is a super master who has made pioneering contributions to the theory of traditional Chinese medicine.What did the Ming people say in their biographies?In "Danxi Weng Biography", although the author Dai Liang introduced Danxi Weng's medical skills with a lot of pen and ink.But the last paragraph still exposed the contempt of Chinese scholar-bureaucrats for the profession of doctors: Zhu Danxi studied Confucian classics when he was young, so strictly speaking, he is the same kind of person as us.Don't look down on him just because he is a doctor.

In a word: You are not an official, you are...

Therefore, when Guan Yi introduced Huangfu Mi as a doctor, Liu Yong was not particularly enthusiastic.

"Jing'an not only has superb medical skills, but also has an extremely noble family character. She is the great-grandson of Huangfu Yizhen's direct line."

"Ouch, it turns out to be the Empress of my Great Han God of War, Huangfu Yizhen. No wonder the medical skills are superb!"

"I don't dare, I can't bear the medical skills like this. But the idea of ​​preventing smallpox that Da Sima proposed to me is really amazing!"

"What? Zifeng? Do you have a way to prevent smallpox?"

Of course, although in the historical plane, Dr. Jenner has gone through untold hardships in researching and promoting the vaccinia method.But the technology content here is not high.As long as you figure out the theory, it is actually very simple to copy it.

In the Three Kingdoms era at the end of the Han Dynasty, the population reduction due to wars was actually limited.The real, biggest culprit is actually the disease.Specifically, it is the plague (infectious disease).

Opening the history books of this period, the records of the great epidemic and the death of the whole city are vivid.

Because of the backwardness of medical technology and epidemic prevention concepts.The damage caused by the plague in ancient times is not the same as that caused by modern epidemic diseases. The SARS in 2003 is believed to be deeply remembered by modern people. At that time, the atmosphere of panic across the country was extremely strong.Hardest-hit areas such as Beijing, Guangdong, and Hong Kong are like purgatory.The final statistics of the World Health Organization are: a total of 8422 cases and 919 deaths worldwide.In 1232 A.D., on the eve of the end of the Jin Dynasty, a plague broke out in the city of Kaifeng. The history books at that time said: more than [-] people died from various schools, and many of them were too poor to be buried.In other words, the death toll far exceeds one million in Kaifeng alone!Almost the whole city is dead!It is precisely because of this that the Jin Dynasty was no longer able to resist the Mongolian attack.eventually perish.

Therefore, in ancient society, all kinds of severe infectious diseases were the biggest enemy of population growth!

As a time traveler, Guan Yi certainly knew how to solve the problem of cowpox cultivation.Not only that, at least Guan Yi has read some basic biological knowledge.Know that the best solution to an infectious disease is not in treatment but in prevention.

How to prevent it?Different diseases have different prevention methods.For various infectious diseases caused by viruses, it is the most economical and effective way to vaccinate people who are not sick in advance.

Still the same sentence: In the past, the Shu Han was the weakest, and the extensive promotion of various epidemic prevention methods was seeking a dead end.Many technology trees only dare to click at this time.After winning Yongliang, Guan Yi unlocked agricultural technology points such as potatoes, new rice, and Quyuanli.The first skill opened in medicine is the prevention of smallpox with vaccinia.

"Hehe, Your Majesty, there are only a few clues at the moment. Some human experiments are still needed to verify whether this inference is correct."

"Hey, what's the difficulty? This king is in charge. You can have as many slaves as you want in the palace of Ganling. As long as you can really prevent smallpox, you will kill all the slaves in this palace. No complaints either…”

Why does this sound so sad?Well, in this era, the views of the superiors towards ordinary people are about the same as those of ants...

"Thank you, Your Majesty, for your generosity. But the servants of the palace are also Han Chinese, so I don't plan to use these people. A few days ago, General Pingbei wiped out the remnants of the Qifu Department in the front and sent about [-] of them. Prisoners of war. Chen and Mr. Jing'an are going to use these people for experiments."

"Hehehe, Shan! Oh, what a surprise! If smallpox can be prevented, then the population of my big man can at least increase by half every year! Mr. Jing'an, I entrust everything to you for this matter. If you don't say anything, I need someone to give it to you." , Ask for money, give money!"

"Thank you, King Ganling! This matter also requires the continued guidance of Da Sima."

"Hehehe, don't dare to be a guide, let's study together and prove each other!"

After introducing Huangfu Mi and his upcoming project, Guan Yi turned slightly and pointed at Liu Hui: "Your Majesty, everyone, this is Liu Hui and Liu Ziyi from Donglai, Qingzhou. Mr. Ziyi is the number one mathematician in the world. His attainments in mathematics, in my opinion, are not inferior to Zhang Pingzi (Zhang Heng)."

"Oh?"

There was really nothing to say except an "oh".For an idle prince like Liu Yong, what the hell is mathematics?Of course Zhang Heng is famous, but in the minds of Liu Yong and others, the seismograph is just a decoration.What Zhang Heng deserves to respect is that his Han Fu is well written.What Guan Yi introduces here is that Liu Hui's mathematics level is not inferior to that of Zhang Heng.Well, how high is Zhang Heng's mathematics level?The widow doesn't know.

"Hui Hui is just a commoner, how dare he stand side by side with Zhang Gong. The great Sima Zhesha is here."

"Hehehe, Mr. Ziyi, don't be self-effacing." Didn't it mean that intellectuals are very arrogant?Why does this Liu Hui feel a little inferior? "Well, Mr. Ziyi, what do you think about the trigonometric functions that Yi mentioned to you a while ago?"

"Da Sima!" As soon as academic issues were mentioned, Liu Hui's demeanor immediately became lively: "Da Sima is really a heavenly man, and he actually proposed such a theory that has never been seen before. With this thing, many people in the past could only rely on experience." The completed structure will become traceable! I am confident that it will be perfected within half a year, and then it can be used in practice and guide production as Da Sima said!"

Mathematics, the foundation of natural science.Trigonometric functions are relatively basic things in the huge subject of mathematics.But even so, with it, surveying and mapping, architecture, cartography, and even future navigation have the most basic theoretical and scientific basis.

"Your Majesty, colleagues. Mathematics contains a lot of content, and it is closely related to our actual life and even the country's political affairs. The simplest one is that without mathematics, houses cannot be built, and royal dignity cannot be displayed. Without mathematics, land cannot Measurement and taxation are out of the question. Without mathematics, the scale of the map is distorted, and it is impossible to guide marches and wars... Based on this, physics, chemistry, astronomy, geography, etc. are developed. This is the guarantee for the prosperity of my great man in the next thousand years. And all of these The founders are all on the shoulders of Mr. Ziyi."

After listening to Guan Yi's explanation, the people who didn't pay much attention to Liu Hui changed their attitudes in an instant. Everyone bowed their hands to Liu Hui again and again, which made Liu Hui, who had always been humble, very uncomfortable.

"Mathematics, medicine, these two most important subjects in the natural sciences, I have found the best leader of this era. I just want to really harvest, I don't know when it will be. Well, if the seeds are sown, the total It's better than doing nothing."

After clearing up his mood, Guan Yi said to everyone: "Everyone, the things here are almost like this. Next, hurry up and eat, and then we will go to Wuzhangyuan!"

　Cough cough, the next chapter is not about Wuzhangyuan College, that will be moved to the end.
