Chapter 7. Circumferential Geometry

In theory, wealthy families must have wealth and knowledge (of course, it refers to Confucian knowledge) is the rank of officials. Officials open up the family's family. But on the other hand, wealthy families may not be among the aristocratic families. Although most common people in the single family are small and medium-sized landlords, they occasionally make a fortune through business or other means. Especially in the troubled times, old officials fell and new nobles rose, but those new nobles did not have enough background. It is not certain whether they could grow into aristocratic families.

However, overall, the cost of books is still high (even if paper has been popularized in the Central Plains, printing workshops are emerging one after another), and the popularization of knowledge is not widespread. Even the common people of the family have dozens or hundreds of acres of land at home. Otherwise, where can they get the remaining money to buy books and go to school? The so-called poor scholars just say that they are relatively poor among scholars, relatively rather than absolute.

Confucius once praised Yan Hui: "A single vegetarian food, a single gulp of drinks, in a humble alley, people can't bear the worries, and Hui will not change his happiness." But after all, Yan Hui belongs to the slave owner class after all, and at least "a single vegetarian food" can fill his stomach. If he is a commoner, even Confucius, who advocates "there is no difference in religion", may not be willing to accept him as his disciple.

It was Hongfu who created the imperial examination system, one to respond to the "talent-only exercise" policy and make the bureaucratic system more efficient, and the other to support the common people of the family and open up the path to rise to them. For this reason, he did have a lot of thought and gave great benefits and help in financial resources. For example, the scholars who applied for the exam first gathered in various counties, and then sent them to Luoyang by bus, and the food and accommodation on the way were reimbursed by the official.

What, you said you don’t have enough money to go from the countryside to the county town and then to the county seat? This is really abject poverty. It’s better to go back to farm honestly. The upper class is not set up for you. You can’t get in at all. With the low productivity and small government status in this year, the country has no financial resources to popularize any nine-year compulsory education.

It is Hongfu that only wants to support common landlords and relatively expand the scope of the ruling class, so he does not want to do anything that citizens have equal right to education. One step beyond the times is a great man, a prophet, and ten steps beyond the times are a delusional man and a charlatan. Although "kings, princes, generals, and ministers, would rather have a seed", basically ordinary people want to be the masters of their own country. There is only one way to rebel.

So the thirty-money "Dictionary" actually forms an invisible threshold, and the poor class cannot squeeze in at all. Of course, Hongfu himself just issued instructions to various places to issue the "Dictionary" uniformly, but bookstores in various places cannot be so selfless, providing hundreds of sets of books for free. As Zhang Xiu said, "only collect workbooks", it is considered very conscientious.

The problem is that Ma Jun doesn’t even have thirty dollars on him…

Ma Jun can barely be considered an extremely poor class. But he can afford to study without tuition, which is naturally different from ordinary people. There are still family forces to support him. Theoretically, as long as the martial arts Ma family has not declined, at least he orphans and widows will drink a mouthful of porridge and will not starve to death. Therefore, facing such a dilemma, the first thing he remembered was the clan, that is, he borrowed from Ma Qi and Ma Xia Shang, and promised to return it if he passed the exam.

However, the two sneered: "How can you win?" They looked down on him at all and refused to pay for it. Yes, the clan would not let you starve to death, but they did not have the obligation to support you as an official. And if you have poor grades, it would be fine. If you do well in the exam, will you pull us back and squeeze out our seats?

In the end, Chen Feng took out the money and helped Ma Jun buy a set of "Dictionary". He cared about Ma Jun: "Those who work hard should not let my expectations down." If you fail the exam, I will never borrow "The First Words of Physics" from now on.

Ma Jun thanked him very much and carefully left with the "Dictionary". Although he was still full of "physics", he also knew that this exam directly affected his future. If he failed the exam this time, there would probably be no next time. The family would not allow him to continue trying, so he had to go back to guard the mill and did not put it down. In just five days, he read the "Dictionary" three times.

Chen Feng also lived in the county school to study hard, with only Ma Xia and Ma Qi. It was rare for young people to come to the county town, and they could not help but travel together. They all got involved in famous scenic spots outside the city, historical sites, restaurants and ladies inside the city.

Finally, the day of the first exam is set up, and the location is located in the county school. As Zhang Xiu said, the exam is divided into two games. The first exam is the meaning of the classics. The test is the three paragraphs of the classics: "The sixth day of the first day, Jun Heng, Zhen, and no profit. First, there is a minister, pardon small mistakes, and talented people. In the fourth month of Xia, Ji Si, Jin, Qi, Song, Qin and Chu people fought in Chengpu, and Chu soldiers, and Chu soldiers were defeated." You can choose one of the sentences, indicate the source, write down the whole paragraph, and analyze and explain it.

Chen Fu signed up for the Mingjing. In order to show off his skills, he chose the first sentence, which is more difficult. Ma Jun did not dare to advance, so he honestly chose the second sentence from the Analects of Confucius. Ma Xia and Ma Qi also applied for the Mingjing, and all chose the third sentence. The word "Chengpu" was revealed. Can't I guess what book and what scripture it is?

In the second session, Ma Jun received the test paper and saw it. It was very simple. It was basically all questions about multiplication and division. One of them was: "The circle was 124 steps, and ask how much the diameter was?" He frowned and thought for a long time, but finally decided to give two answers: "According to "Zhoubian", the diameter was one to one on Wednesday, and one on three steps; according to Zhang Pingzi (Zhang Heng), it was about thirty-nine steps, one on five steps."

He hadn't read the fourth volume of "The First Words of Physics", otherwise he would probably give the third answer to "about thirty-nine steps, five steps, two" (39 and 2/5). Because it was Hongfu's first and no calculation process was given, he directly revealed a brand new pi, which actually reached the tenth place after the decimal point! Originally, he was a liberal arts student, and he was very insensitive to numbers, and it was impossible to memorize pi, but he was sensitive to Chinese. When he was a child in his previous life, he memorized two rumors, saying: "A temple on the mountain and a pot of wine, and I was so happy that I was just tenth place.

"The First Words of Physics" was written by Hongfu. He had a great reputation and a high official position. Naturally, scholars from all over the world gathered in his disciples, including those who knew astronomy, calendar, and mathematics. There were all kinds of types. So he brought out many knowledge of astronomy, physics, chemistry, mathematics, and engineering that were not high-end for later generations. He gave it to the guests to join them into a book.

It's just that a lot of knowledge is not clear, or he knows it but doesn't know why, but it doesn't matter. Just leave all the troublesome things like calculation and argumentation to the guests. His disciple Zhuge Kongming also worked a lot in related astronomy, numbering and engineering.

But only this pi is the only way for Hongfu to recite the ten digits after the decimal point, but he really doesn't know how to calculate it. No one under his command understands it. In this year, people generally accept the word "one diameter and Wednesday" as mentioned in the "Cibo Sutra". That is to say, three times the diameter of the circle is the circumference length. The error is really too large. In addition, Zhang Heng proposed a new calculation result decades ago, which is about ten squares, which is 3.162, and the true accuracy is only one digit after the decimal point.

It took decades before mathematician Liu Hui used the "circle-cutting technique" to calculate the fourth position after the decimal point (3.1416), and then the Southern Dynasty Zu Chongzhi was accurate to the seventh position after the decimal point (between 3.1415926 and 3.1415927). He maintained a leading position in the world for 800 years. Therefore, it is impossible for anyone to know how to calculate the circumference in more detail in this year and month. Even if Hongfu gave the answer to the ten decimal point, no one could do it if he pushed it back.

I thought for a long time, although like many of the wrong views I ridiculed in my book, pseudo-technology only gave the results without listing the calculation process. Hongfu finally recorded this number in a grand manner...

Let’s talk about the first test, Ma Jun met with three friends who were planning to apply for the Mingjing exam and said that my Mingjing question is very simple. What’s wrong with you? Chen Feng replied expressionlessly: “It’s so difficult for the first test.” Ma Qi was short, so he was often forced to look up at people, so he developed the habit of shy breasts and bulging belly. He now looked like a heroic spirit and patted his chest: “It’s three times more difficult, and I will win.” Only Ma Xia kept wiping the oil and sweat on his neck, refusing to make any statement.

The speed of the papers was unexpectedly fast. It was estimated that the county government itself did not want to screen out too many scholars. The result was released the next day, and only 16 were eliminated. Most of the candidates were considered qualified to go to Luoyang. It was a pity that Maxia and Madehua were also dismissed.

Ma Xia kept complaining, saying that I was unable to perform as well because I had a stomachache two days ago. But with his background, I only dared to cry with my companions. I didn’t have the courage to report to the county government, so I had to return home in shame. However, several children of aristocratic families openly filed lawsuits with the county government and demanded a re-examination. Wang Yuanbo directly ordered people to go out.

The Wang family of Langya is the real family and famous in Kanto. Since Guanxi was ravaged by Dong Zhuo, Li Jue, Guo Si, Han Sui, Ma Teng and others, there are still a few wealthy families left? How dare you compare with him? Besides, the Wang family is still married to the current Taiwei, Hongfu and the family, so how could he be afraid of local snakes like Fufeng?

The candidates who stayed continued to study hard under the supervision of the county school professors until the sun was sunny, and then worshiped the heaven and earth, the master, and then sent chariots and county soldiers to escort them. They left Wugong in a mighty way and headed for Luoyang. Nearly one hundred people crowded together seven horse-drawn carriages or donkey carriages (there was no choice, there were only so many vehicles in the county government, and half of them could only be tied). There were four ox carriages carrying food and tents behind them. Although the official family had all the food and accommodation, there were so many people that it was impossible for you to eat, stay and stay along the way. You had to sweep the entire way like a locust.

First, he arrived at the Wei River. There were ships prepared in advance and all the candidates were on board and entered Guanzhong through Huaili. The next stop was Changling, and then Yangling Guanzhong, Fengyi County went east from here, which was bounded by Wei River. Then he immediately put the waterway east of Zheng County. The waterway east of Zheng County was tortuous and inconvenient to sail, so the candidates were arranged to stay outside the city for two days, temporarily wash away the dust, or wait for the luggage coming from land. Ma Qi also wanted to go into the city to play, but unfortunately Ma Xia was deposed and returned to his hometown. He was alone and had no friends. This trip was lonely and a little scary. So he persuaded and pulled and finally told Chen Feng and Ma Jun to put down his books for a day and went to the city for a meal.

Of course, the son of the dignified patriarch has a lot of money, so of course he, Ma Boyong, has to treat him.

It was the autumn harvest season. I walked all the way, but I saw the golden waves of wheat and dancing with the wind. The farmers in the fields were busy driving sickles to harvest, and pouring a picture of peace. Chen Feng said to his companions: "Guanzhong is not far from Fufeng, and the climate is extraordinary. Now that Guanzhong is well-versed, I hope that I can also have a good New Year for Fufeng."
