Chapter 549: Goodbye Zhang

Zhao Pan and Zhao Lu glanced at each other, and they both saw the gloating look in each other's eyes, and Zhao Pan immediately said lightly: "After Jiefu goes straight, go home and try it yourself, don't you know......"

Shen Kuo is now living a very nourishing life, and when he came back from a trip to Hebei, the map he made attracted the attention of the river affairs and the military, and now he can be regarded as a person whose name the emperor knows.

Proofreading books is a job, and studying cold knowledge is fun, but it's a pity that several experts went to Zhengzhou, and when Shen Kuo used a small wooden stick to build the map that Suyou said in Hebei, he also deliberately used trigonometric functions to offset the height difference, if the ground has no curvature, then it should be a plane.

However, now that most of the area has been spliced together, theory and practice are completely unified - the ground, there really is curvature!

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

This discovery was obviously great, and Shen Kuo felt as comfortable as pouring rain all over his body, holding a small stick in his hand, and he was even more energetic.

After thinking about it, this matter can only be discussed with the blind man tomorrow to see what he has to say.

Thinking of this, I can't help but feel funny, this really fulfills that sentence - the pretty eye is made for the blind man.

Just then, there was a knock on the door outside the rental house.

Shen Kuo opened the door, but it was two fast shifters: "Shen Xiaokan, please participate in politics." ”

Shen Kuo hurriedly asked, "Which one is involved in politics?" ”

Kuaiban proudly: "Of course it's Jiefu Gong." ”

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

When I came to the palace, I saw Wang Anshi, Lu Huiqing, and Wang Yan gathered around the table, and there were a few pieces of Meishan stone paper, rulers, and some messy circles on several cases.

Shen Kuo stepped forward: "See Participating in politics, I've seen Zhongyun, and I'll talk about it directly." ”

Lu Huiqing smiled and introduced to Wang Anshi: "Cunzhong is the county order of Jiayou for six years, and the Jinshi of Jiayou for eight years, and it is still earlier than the imperial examination. Zhiping entered the Zhaowen Museum in the third year, and the astronomical calendar and arithmetic numbers are also famous in Beijing. ”

Wang Anshi nodded: "I heard that you are very interested in water conservancy?" Wanchunwei has a picture and a style, and it can be in the south of the Yangtze River, so Su Mingrun inspected Hebei and specially named your name? The map of Beiliu drawn this time is quite detailed, and he is a good talent. ”

Shen Kuo didn't even dare to say: "Shen Kuo is ashamed, before leaving, he didn't expect that Master Su's requirements would be so meticulous, and he relied on his experience in daily cartography, plus the three-point method of Meishan, fortunately he was not disgraced." ”

Wang Anshi said: "Today, when talking about science and technology in front of the emperor, His Majesty said that only the ruler gauge is used, and the circle can be divided into five equal parts. ”

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

Wang Yan sneered: "Isn't it Mo Zhai Luban's legacy skills?" Have you risen to the level of thinking? ”

Shen Kuo didn't say anything: "Craftsmanship is empirical, for example, drawing a one-foot-long line segment, as long as you put the pen down, there will always be errors, and it can't be a perfect one-foot." ”

"The science of geometry is to assume that the ruler is a perfect ruler and then to reason for it. For example, if you divide a perfect circle into five, it is like this......"

After finishing his homework on the diagram, he quickly divided a circle into five parts.

Shen Kuo continued: "Although it is a drawing, when we infer it according to the drawing, we first assume that it is perfect, and then make an inference. ”

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

Take this diagram as an example, through derivation, from simple to complex, step by step to prove, according to this technique, it is five points. This is the study of using the proven method to deduce the unproven way, which is called geometry. ”

After speaking, he began to explain the proof of method.

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 of Shu were better than the scholars of the Ming Dynasty, and now it seems that it is not a lie...... By the way, do you know how to do the question of three five and one to make up twenty-four? ”

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

Lu Huiqing asked: "In the middle of the deposit, you can take four out of five, take three, take two, take one, how can you get twenty-four out of five?" ”

Only then did Shen Kuo react and wrote an equation on the paper: "Oh, this is the expression method of mathematics in Shuzhong, which belongs to the concept of fractions, and there is a matching formula to write it accordingly, translated into nine chapters, well......"

Translated into nine chapters, it should be ...... One point and five is to take one of them, which is divided into five days, so five is divided into twenty-five parts and five points. Go to one of them, and the remaining twenty-four parts will be divided into five days. If it is divided into five parts and five five, it is one; Therefore, the five roads and twenty-four parts of the five-one division are divided into twenty-four. ”

This expression is extremely awkward and prone to misunderstanding, but everyone understands it.

Wang Anshi compared the two statements, then looked at the simple formula that Shen Kuo wrote on the paper, and sighed: "If it is not the posture of heaven and man, how can it be so far...... It's another way to discover the avenue of inquiry! Shu science and engineering, even considerable! ”

After speaking, he said to Shen Kuo: "In the storage, Su Mingrun recommended two talents to me, one is Zhang Zihou, and the other is you, the account books of the accounting department are all taken from the new method, in which the formatting method, symbols and words, the old man is relatively unfamiliar, are you willing to stay with me for consultation?" ”

Shen Kuo's heart was pounding, secretly overjoyed, and hurriedly bowed deeply to hide his expression: "Shen Kuo's firefly light, but he is trying his best to be effective, and he is not waiting to be followed." ”

……

Zhengzhou, Songyang Academy, Zhang Dian, Su Shi, Su You, Su Yuanzhen, several people are drinking and chatting together and eating barbecue.

Su You looked at Su Shi, who was frantically masturbating, and sighed: "I said Zizhan, what are you doing when you have nothing to do with participating in politics?" ”

Su Shi didn't care: "What kind of tiger whiskers, I am a clever admonition." ”

This baby has just finished being the examiner of the country, and there is an exam question - "Jin Wuping Wu is independent and restrained, Fu Jian and Jin are killed by arbitrariness, Qi Huan is a full-time manager of Zhong and hegemonic, and Yan Xu is a full-time son and is defeated, and the same thing is different." ”

This is a clear satire of Wang Anshi's arbitrariness.

Su You rolled his eyes: "It's unpleasant to see flies again, right?" That's still for participating in politics, Brother Zhang is still here. ”

Zhang Dian smiled: "The distinction between public and private is clear, so I shouldn't have heard it." ”

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

Su You touched a glass with him: "Thank me for what, but your temper should also be changed, otherwise, with your brother's talent, why did you fall for so long?" ”

Zhang Dian smiled: "Every time I hear the same column, I don't feel busy." There are days to advance and retreat, and temper is your own. You can't change it, you will get sick if you change it, I don't believe you ask Zizhan if this is the case. ”

Su Shi raised his glass and touched him with one: "Good sentence!" Good solution! When a big white with the son thick floating! ”

Su You waited for a long time: "What about the back?" That's it? ”

Zhang Dian smiled: "As soon as I wrote here, I received the imperial edict, and now it's the turn of others to be busy, but what am I going to do?" Are you looking for bad luck? ”

Everyone laughed.

Su You didn't bother to pay attention to him, and said to Su Yuanzhen: "Yuanzhen, I took leave for you and Taixue, there is chaos in the capital now, I know very well what virtues Taixue has, I don't dare to laugh when I listen to their nonsense and scolding, it's very hard, right?" ”

Everyone laughed again, scolding Su You for his lack of morality.

Su Yuanzhen followed Su You, General Fuyuan, his own eldest brother and sister have cooked practically, civil and military affairs, and the articles have always been on the top, deeply favored by Taixue teachers, and also have appeal among students.

Su You put out the pedigree of the parent's agent to take him out of Taixue, under the pretext that Zhengzhou was short of people, and recruited him as the military weapons supervisor and the commander of the machine, but in fact, he was afraid that he would be hot-headed, or he would be instigated and framed, and the new policy would be slandered and fall into a court dispute.

With a guy like Su Shi who doesn't make people feel at ease, the scholars can't be quiet.

Su Zhe sighed: "This regulation department, I'm afraid I won't be able to stay anymore." ”

Su You was also a little depressed: "When the "Equal Loss Law" was implemented, I wrote letters to Jiefu Gong and Xue Xiang, pointing out several inappropriate places, and hoping that some content could be added to the regulations...... It's a pity that the decree was issued, and it was useless. ”

Zhang Dian was a little surprised: "Mingrun, do you support the new law?" ”
