Zhao Pian and Zhao Xu looked at each other, and both saw the look of gloating in each other's eyes. Zhao Pian immediately said calmly: "After Jie Fu gets straight, go home and try it yourself, and you will know..."

Shen Kuo is living a happy life now. After returning from a trip to Hebei, the map he made attracted the attention of the river administration and the military. Now he is considered a person whose name is known to the emperor.

Collating books is a real job, and studying cold knowledge is fun. It is a pity that several experts have gone to Zhengzhou. When Shen Kuo used small wooden sticks to build the map Su You of Hebei Province mentioned, he also deliberately used trigonometric functions to offset the height difference. If the ground

Without curvature, it stands to reason that we should get a plane.

However, now that most areas have been spliced ​​together, theory and practice are completely unified on the ground, and curvature really exists!

The map spliced ​​together by wooden sticks is obviously a curved surface!

This discovery was obviously great. Shen Kuo felt as refreshed as if the rain had poured down on his whole body. He held the stick in his hand and worked even more vigorously.

After much deliberation, I can only discuss this matter with the blind magic expert tomorrow and see what he has to say.

Thinking of this, I couldn't help but feel funny. This really fulfilled that sentence and showed my charming eyes to the blind man.

At this moment, there was a knock on the door outside the rental house.

Shen Kuo opened the door, only to see two quickies: "Colonel Shen, please join us in politics."

Shen Kuo quickly asked: "Who is participating in politics?"

Kuaiban Aoran: "Of course it's Duke Jiefu."

Shen Kuo quickly put down the wooden stick in his hand: "Please lead the way."

When they arrived at Wang's house, they saw Wang Anshi, Lu Huiqing and Wang Yu gathered around the table. On the tables were several pieces of Meishan stone paper, rulers and compasses, and some random circles.

Shen Kuo stepped forward and said, "I've seen Participating in Politics, I've seen Zhong Yun, I'll tell you directly."

Lu Huiqing smiled and introduced to Wang Anshi: "Cunzhong was the county magistrate in the sixth year of Jiayou. He was a Jinshi in the eighth year of Jiayou. He entered the officialdom earlier than the imperial examination. He entered the Zhaowen Hall in the third year of Zhiping. He is famous in astronomy, calendar and arithmetic.

.”

Wang Anshi nodded: "I heard that you are very knowledgeable about water conservancy? Wanchunwei has pictures and styles that can be used to travel south of the Yangtze River, so Su Mingrun inspected Hebei and specifically named you? The map of Beiliu drawn this time is quite detailed, and it is a good idea

Talents."

Shen Kuo repeatedly said that he did not dare: "Shen Kuo was ashamed. Before setting off, he did not expect that Xu Xueshi required such a level of detail. He relied on his usual drawing experience and the Meishan three-point method. Fortunately, he did not disgrace his mission."

Wang Anshi said: "Today we were talking about science and engineering in front of the emperor. Your Majesty said that you can divide a circle into five equal parts using only a ruler and compass. Can you tell us how to do this?"

Shen Kuo said: "This is called the study of geometry in science and engineering, but it is actually also the study of thinking."

Wang Xun sneered and said: "Isn't it the legacy of Mo Zhai and Lu Ban? It has also risen to the level of thinking?"

Shen Kuo had nothing to say: "Working skills are empirical. For example, if you draw a line segment one foot long, as long as you put down the pen, there will always be errors, and it cannot be a perfect foot."

"The science of geometry is to first assume that this foot is a perfect foot, and then to deduce its rationale. For example, dividing a perfect circle into five parts is like this..."

After talking about working on the picture, I quickly divided a circle into five parts.

Shen Kuo continued: "Although it is a drawing, when we make inferences based on the drawings, we first assume that it is perfect and then make inferences."

"A truly perfect picture can only exist in our hearts. Therefore, Su Mingrun said that it is the study of thinking. I think it makes sense."

"Take this diagram as an example. Through deduction, from simple to complex, it is proved step by step. According to this technique, it is divided into five points. This science of using proven methods to deduce unproven ways is called geometry."

After that, he started to explain the method proof.

By the time the verification was completed, the three of them were all smart people and had already understood the truth.

Wang Anshi shook his head and said: "Su Mingrun boasted that the children from Shu were better at math than the mathematicians. Now it seems that it is not false... By the way, you know how to solve the question of three, five, one and twenty-four.

?"

Shen Kuo smiled and said: "This is not difficult. One divided by five is one-fifth, five minus one-fifth is twenty-four-fifths, and twenty-four-fifths multiplied by five is twenty-four."

Lu Huiqing asked: "In the deposit, if you take five points, you can take four, take three, take two, take one, how can you get twenty-four fifths?"

Only then did Shen Kuo react and wrote a formula on the paper: "Oh, this is the way to express mathematics in Shu. It belongs to the concept of fractions. There are matching formulas corresponding to it. It is translated into nine chapters, um..."

"When translated into nine chapters, it should be...one divided into five is to take one part and divide it into five and one parts. Therefore, five is divided into twenty-five parts and fifty-one parts. If one part is removed, the remaining twenty-four parts and five parts are divided into five parts."

Divided into one. If the five divisions and fifty-one divisions are combined, it becomes one; therefore, when the five roads and twenty-four divisions are combined into fifty-one divisions, it becomes twenty-four."

This way of expression is extremely difficult to pronounce and can easily lead to misunderstandings, but everyone understands it.

Wang Anshi compared the two statements, then looked at the simple formula written by Shen Kuo on the paper, and sighed: "How can we reach this point without the appearance of heaven and man... This is another way to explore the great road!"

The science and engineering in Shu is very impressive!"

After saying that, he said to Shen Kuo: "Cunzhong, Su Mingrun recommended two talents to me, one is Zhang Zihou, and the other is you. The accounting department's account books are all based on the new method. The formats, symbols and characters are relatively unfamiliar to me.

Are you willing to stay with me for consultation?"

Shen Kuo's heart was pounding, and he was secretly overjoyed. He quickly bowed deeply to cover up his expression: "Shen Kuo's firefly light is just to work hard to achieve results, and hope not to miss the results."

…

Zhengzhou, Songyang Academy, Zhang Dun, Su Shi, Su You, Su Yuanzhen, a few people were drinking, chatting and eating barbecue together.

Su You looked at Su Shi who was frantically masturbating, and sighed: "Zizhan, what are you doing trying to get involved in politics when you have nothing to do?"

Su Shi didn't take it seriously: "What are you trying to do by stroking the tiger's beard? That's my clever advice."

This boy had just finished serving as the Imperial Examiner, and an exam question came up: "Jin Wu defeated Wu with his dictatorship, Fu Jian defeated Jin with his dictatorship, and died, Qi Huan was appointed as Guan Zhong and dominated, Yan Kuai was appointed as his son, and he was defeated, and he achieved success by doing the same thing.

different."

This is a clear irony of Wang Anshi's arbitrary behavior.

Su You rolled his eyes: "You are unhappy when you see a fly again, aren't you? Then it is still about participating in politics. Brother Zhang is still here."

Zhang Dun smiled and said: "We can distinguish between public and private affairs, so I just pretended not to hear it."

After speaking, he raised his glass: "I haven't thanked Mingrun yet."

Su You had a drink with him: "Why thank me, but you should also change your temper. Otherwise, with your talents, brother, how could you have been in decline for so long?"

Zhang Dun smiled and said: "Every time I hear that my colleagues are advancing, I feel busy. You have your own days to advance or retreat, and your temper is yours. You can't change it. If you change it, you will get sick. If you don't believe me, ask Zizhan if this is the case."

Su Shi raised his glass and touched it with him: "Good sentence! Good explanation! It's obvious when you are thick and superficial!"

Su You waited for a long time: "What's behind? That's it?"

Zhang Dun smiled and said: "I just finished writing this and received the imperial edict. Now it's other people's turn to be busy, but why should I continue? Am I asking for bad luck?"

Everyone laughed.

Su You was too lazy to pay attention to him and said to Su Yuanzhen: "Yuanzhen, I asked for leave for you and the Imperial College. There is chaos in the capital now. I know very well the virtues of the Imperial College students. I don't dare to laugh after listening to their nonsense. Is it very hard?"

Everyone laughed again and scolded Su You for his immoral statement.

Su Yuanzhen followed Su You, General Fuyuan, and her eldest brother and sister did practical work. She was good at civil and military matters, and she kept writing articles. She was deeply loved by the teachers of Taixue, and she also had charisma among students. She was not that kind of person. Taixue Qingliu, who only knows how to talk nonsense.

Su You used the pedigree of his parents' agents to get him out of Taixue. The excuse was that there was a shortage of people in Zhengzhou and he was recruited to serve as an arms supervisor. In fact, he was afraid that he would be hot-headed or be instigated to be framed and slandered. The New Deal fell into political strife.

With a troublesome guy like Su Shi around, the scholars couldn't be quiet.

Su Che sighed: "I'm afraid I won't be able to stay in this Department of Regulations any longer."

Su You was also a little depressed: "After the implementation of the "Uniform Transmission Method", I, Duke Jiefu, and Xue Xiang both wrote letters, pointing out several deficiencies in it, and hoped that some content could be added to the decree... Unfortunately, the decree was promulgated. , a useless sentence.”
