Northern Song Dynasty Revitalization Strategy

Chapter 447 The Collision of Theory and Application
Zhao Huan asked Li Gang and Liu Yi to come up with a set of textbooks that are not so difficult to understand, suitable for training from childhood.

Li Gang published a book on the principle of mechanics, and worked out some elementary subjects of simple mechanical structures such as levers, connecting rods, cams, gears, and screws.

There are also intermediate-level subjects on the slightly complicated principles of intermittent motion mechanics. After review, Zhao Huan believes that the elementary textbooks can be learned by children over 14 years old, while the intermediate-level textbooks are suitable for students over 17 years old.

As for the mechanical principle of the advanced version, Li Gang is still groping.

When pure mechanics has not yet begun, applied mechanics has been studied a lot.

Liu Yi, who has been baptized by Tongwen's counting finger, now has a wealth of mathematical tools. Like Li Gang, he has compiled a set of textbooks suitable for ages six to 14, and textbooks for ages above 14.

Zhao Huan exchanged two mathematics books and physics books for junior high school and high school for the two of them to study. Purely theoretical science, these things are too difficult to study and understand.

When Li Gang received the books mailed back from Yanjing, his eyes were full of despair. Did he offend the officials of the Zhao family?

He is very busy, he is in Fuguo!

Researching these really consumes too much energy!
Of course, Li Gang and Liu Yi didn't dare to discuss Mr. Zhao's family, so they took their anger out on Zhao Chen, who was only nine years old.

"There is a patch of grass in a pasture that grows equally fast every day. Ten cows will eat this patch for 22 days, or sixteen cows will eat it for ten days, and the grass will grow all the time. If you feed 25 How many days can a cow eat?"

Zhao Chen bit his pen and looked at Liu Yi who was sitting in front of the stage, looking at this question in pain, he really couldn't.

"Master, how do you do it?" Zhao Chen gave Liu Yi a blank answer sheet. Liu Yi looked at it, pulled out a ruler, and said, "Hand out your hand."

Yue Yun, Yu Wenzhong and Zhao Chenfu stretched out their hands together and looked at Liu Yi eagerly. This question is really difficult, and none of them know how to do it.

Even the smartest Zhao Chenfu can't.

Liu Yi laughed wildly in his heart, this was sent by the Song Dynasty officials from Bianjing to embarrass him Liu Yi!

Fortunately, Liu Yi had a few brushes himself, and was almost intimidated by this cloudy question.

However, under his equation technique, it took only a moment to make it, but the ebb and flow of mathematical ideas inside still brought Liu Yi one step closer.

"Forget it, put your hands down. Let me explain to you." Liu Yi smiled and made several people retract their hands.

"To solve this kind of problem of ebb and flow, we must first clarify the basic characteristics. The amount of grass and the growth rate of grass are constant. After finding this basic characteristic, we can find two constants from this question. amount." Liu Yi wrote two amounts on the blackboard.

Yue Yun didn't like mathematics very much. He looked up at the window and saw the birds on the branches outside the window, chirping non-stop.

He swears, he just took a look.

As soon as I turned around, I saw Liu Yi writing two common formulas and four basic formulas on the blackboard.

"Yue Yun, repeat what I just said!" Liu Yi said, staring at Yue Yun very seriously.

"I don't know." Yue Yun was an honest boy, and honestly admitted that he lost his mind in class.

Liu Yi's ruler landed on Yue Yun's palm with a sound of piercing.

"Snapped!"

"Hiss..." Yue Yun shook his palm, sat down quickly, and listened carefully to the class. Liu Yi is a very good teacher. He sorted out the quantitative relationship again and said, "Okay, from this, we Easy to get, 25 cows, need five and one-half days to eat the grass."

"Master, what's the use of us learning this?" Yue Yun boldly raised his doubts.

Liu Yi glanced at Yue Yun, he and the group of Confucian classics doctors in the court hall asked exactly the same questions.

These questions are completely out of touch and completely useless.

Zhao Huan named this kind of mathematics as pure mathematics, and the applied mathematics was called applied mathematics.

"When you planted trees, did you dig holes?" Liu Yi asked with a smile.

"Planing." Yue Yun said quickly.

"When you planted a tree, did you water it?"

"Water."

"When you plant a tree, do you want saplings?"

"want."

"When you plant a tree, do you plant it in the sky?"

"No, I will die of drought."

"That's right, there is no big tree in the sky that can't stand on the ground. The mathematics we are learning now is pure mathematics. Their function is to exercise our thinking and logical ability."

"Then let the big tree of mathematics grow vigorously, and the fruit it bears is applied mathematics." Liu Yi asked Yue Yun to sit down, looked at him and said.

"Specializing in the study of mathematics itself, not for the purpose of practical application, is pure mathematics, which studies the inner connection of mathematical laws abstracted from the objective world."

"It can also be said that pure mathematics is the study of mathematics itself. Making mathematics our tool to solve practical problems is the meaning of our learning." Liu Yi finished his words and continued today's lesson.

The concept of pure mathematics is not mature, it is just a simple summary in Zhao Huan's reply to Liu Yi's letter, and he has made a summary.

What he said, children may not understand, but they may not understand, as long as they know, what they learn is not useless.

Li Gang was sitting in the court hall. What he was facing today was not the courtiers, but the doctors from the Taixue and Guozijian. These doctors are a group of old scholars.

It is too difficult to change their thinking. The improvement of various weapons of the Military Weapons Supervisor Li Gang is in charge of is the application of mathematics in practice. It is really difficult to explain these things to this group of old scholars.

Today, this group of Ph. D.s finally came to ask Li Gangyao for an explanation, whether this textbook is the textbook from Taixue, or use Li Gang's textbook.

"Here's what I'm talking about today! This new learning is promoted by the government! This teaching material is appointed by the government! If you are looking for someone to reason with, go to the government! The government is in Yanjing! The express train will arrive in ten days. The slow 20 days will come soon!"

"The new learning is these textbooks! It must be implemented!" Li Gang slapped the edict on the table and walked away.

Doctors of Confucianism looked at each other in blank dismay. They thought that their senior qualifications could sit down with Li Gang and discuss whether there was room for revision of these textbooks.

As a result, Li Gang didn't give them a chance at all.

Li Bangyan stood at the gate of Wende Hall, all bent over with a smile.

He walked in and said with a smile: "The textbooks are all here, and Dasong Bookstore has printed them all. You have to learn it yourself before you can teach students. Hurry up and take it back for research."

"It's the same reason for the teachers of the Work Relief Supervisor. The new learning will be fully popularized after three months. If the teachers are questioned in class, it will be embarrassing."

Li Bangyan asked the doctors of Confucian classics to leave the Wende Hall. Li Gang made it clear that he was playing hooligans and brought them out of the official house to suppress them.

This is what a butcher should look like, he has to take care of everything by himself, so why keep the official killer?

Doctors of Confucian classics certainly don't have the guts to go to Yanjing and ask the officials to reason.

According to rumors, there are refugees all over the place, and there are swordsmen everywhere, they dare not go to the muddy water.

The textbooks of this new learning spread to all parts of the Song Dynasty at the fastest speed. It is impossible for the Dasong Bookstore alone to print these books. Naturally, bookstores in various places actively cooperated in the printing and unified the teaching content.

When Zhao Huan received Li Gang's letter, he also smiled. This Li Gang finally learned to use the emperor to take the blame.

But Zhao Huan hummed a little song, walked out of Yanfu Palace, and strolled towards the market on the left side of the imperial city.

On the left side of the Yanjing Palace, there is a street that is a bazaar, where almost all the goods in the world are gathered, and merchants gather here. Zhao Huan's activity today is to go shopping with Zhu Lian.

Yanjing was different from Bianjing, almost no one knew him here, so he arranged for some personal officials to follow him, and without clearing the place, he walked out of the palace through the side door.

Zhao Huan stood at the head of this street and looked at the end of the street, bustling with people rubbing shoulders, feeling relieved for a while.

He didn't play off his government orders. After a slight increase in the grain price in the Song Dynasty, it stabilized again. The grain price in Yanjing and Bianjing only increased by half.

Probably from two yuan a catty of rice to two yuan and ten cents a catty of rice.

Both Yu Wenxuzhong and Zhao Huan underestimated the background of the Song Dynasty.

This is a country with a population of nearly [-] million. The people in this land have created the most prosperous oriental world in the world with their hardworking hands.

However, this kind of prosperity still reproduced the prosperity of nearly [-] million people under the harsh exploitation of the gentry and landlords.

At that time, Europa had a population of less than 5000 million.

Under Zhao Huan's land reform and business reform that lasted for more than a year, this time, millions of people were accepted into the customs without any waves at all, as if water droplets merged into the sea.

This time, the Northland refugees received a total of 200 million people. Compared with the 2 million population of Song Dynasty, the population has only increased by [-]%.
Zhao Huan breathed a sigh of relief. He was afraid that what Yu Wenxu said would become true, but fortunately, everyone was happy with the result.

Zhao Huan understood what a unified dynasty is, and the content of this unified dynasty is really too much.

It's a whole.

"Misty rain looks for the traces of spring, the earth absorbs spiritual energy, a hundred flowers compete for beauty, and the prosperous age looks at the present." Zhao Huan was about to step into the market, and took Zhu Lian for a good stroll.

Isn't it a pity that I can't blend into the prosperous scene?

When Zhao Huan took the first step, countless servants ran from behind him to the front, and wiped out all the people on the street.

Zhao Huan stared blankly at this scene, he turned his head and glanced at Shen Cong, the word "cautious" completely fits Shen Cong's every move now.

You look a bit reckless, okay?You see, Shen Cong, who killed Jin Guodong Shuai!

"Officials, please, the venue is cleared." Shen Cong looked around and said with a smile.

"You've been chased away, what's the point?" Zhao Huan said angrily, laughing and cursing.

Shen Cong bowed his head and said, "Officials, if the common people accidentally collide with the official, it will be a disaster for the common people. The official, after all, is the official."

Shen Cong's reason for clearing the field was to protect Zhao Huan and the people.

Who made Zhao Huan's identity so special?

The word "emperor" is like a mountain, pressing on everyone's head. Even if the people respect him and follow him blindly, Shen Cong is not willing to risk Zhao Huan.

"Okay, what you said makes sense." Zhao Huan sighed, the chance to have fun with the people in this life is probably gone.

"Officials be careful." Zhu Lian said suddenly.

　Every day is reached, as usual, ask for various rewards, recommendations, monthly tickets, etc.
