Xu Jingchang was sleeping sweetly, and was woken up by his own little girl, opened his eyes in great pain, and asked angrily: "Is the sky falling or is the ground sinking?" ”

The little guy called the abacus, who grew up with Xu Jingchang, and became angry in a hurry: "It's not me who called you, it's the lady who is looking for you." Hurry up! ”

Xu Jingchangqi said: "Isn't she eating wine? What do you want me to do? ”

Abacus hurriedly said: "I said that I wanted to compare with Miss Ye Si, my lord, how did you win her when you were drunk like this?" If she loses, she will go back and describe it in vain, but she is afraid that Grandpa Guo will be annoyed! ”

Xu Jingchang only felt that Ju. The flowers are tight, and the wine is sobered up for the most part. Hurriedly turned over, and said angrily while taking care of his clothes: "Who is excited?" Yes? You asked me clearly, and I turned around and shouted that Brother Eleven had a sack and beat him! "Hemp eggs! Heel leaves. Ting Fang is more arithmetic than arithmetic, and he is dead! He couldn't help but go, he wanted to see who the enemy was.

Three steps and two steps to the east courtyard, the girls were only in the courtyard, and the rest of them were probably all avoided in the house. A group of people stared at Xu Jingchang, and those who had never seen it secretly praised: It's really good! glanced at the Duchess of Dingguo again, alas, if it weren't for the noble family, it would be a good son-in-law, but it's a pity.

Xu Jingchang first met with the old lady, and then saw your orders. He is the companion of King Fu, and he can read books badly, but the etiquette has been immersed in the court for more than ten years, and he is the most calm. Shi Shiran has seen everyone, and the ladies like him more.

When the Duchess of Dingguo saw Xu Jingchang finish saluting, she pretended to be "I'm here to talk to my son", and said with a smug smile: "Come and compare with your sister to see who is better." ”

Xu Jingchang sneered in his heart, I wish I was making a fool of myself! However, under the etiquette law, he can't refute it openly, and he doesn't want to follow his stepmother's path. only smiled: "Which one compares with the fourth sister?" I can't compare to the top cylinder again. Isn't it just that His Royal Highness Fu is here again? ”

Ting Fang smiled: "It's just that His Royal Highness King Fu didn't come, so he called you here." ”

Xu Jingchang looked at Ting Fang sadly, good junior sister, you have killed me! I don't know if I lose in public, will I be beaten by Lao Tzu?

Ting Fang blinked mischievously: "Senior brother, do you have a question for me to do?" ”

Xu Jingchang said categorically: "No! ”

"Oh!" Ting Fangle said, "Then I have it." ”

Xu Jingchang had stepped on 10,000 divine beasts in his heart, and he had to bite the bullet and say: "I'm not a person on the card, what is it that makes me difficult?" It's hard to find the world to be powerful. "Ancestor, don't harm me!

Ting Fang nodded approvingly, she got along well with Xu Jingchang, and she didn't want him to be too embarrassed. If he can't do it alone, it's a shame for him, but he can't do it all day, it's her own face. After thinking about it, he said, "Then I'm out of the question!"

Xu Jingchang closed his eyes in despair and nodded. That's it, Man Po will be beaten up tonight, no matter how bad it is, that's it.

Ting Fang came up with the question quickly and said: "As the saying goes, the sky is round. But the houses we live in are all square, and I want to build a stone domed house, how do I build it? "The so-called dome is something that appeared very late, born in the West with a scientific basis, and is mostly used in churches. Except for the ice and snow dome structure accumulated by the Eskimos with experience, it is rarely seen by other peoples. In ancient China, there were even fewer curved buildings. Because there are stacked beams arched in front and something similar to Zhaozhou Bridge, for the sake of insurance, Ting Fang's question is the church style that most Chinese people have never heard of in this era. Normally, no one can solve it, and even if someone can, it doesn't matter. Nothing else, the question bank has wow! There are still many mathematical riddles that she never solved when she was in school, and she was forced to lose the trick as if she didn't want money, who was afraid of whom! Knowledge is power! Properly.

Xu Jingchang said: "A stone domed house? You tell me first. ”

Ting Fang took a rice bowl in his hand and turned it upside down: "That's it!" To be very large, you can live people. ”

Xu Jingchang thought for a while and asked, "The kind of Mongolians?" ”

Ting Fang nodded: "But it's bigger than the Mongols, much bigger." The diameter is at least 10 zhang. ”

Xu Jingchang raised his eyebrows: "How do you know if I'm doing the right thing?" ”

Ting Fang also raised her eyebrows: "Do you know stress?" ”

Xu Jingchang was confused: "What is stress?" ”

Ting Fang kindly explained: "When something is deformed due to external factors (force, humidity changes, etc.), an internal force is generated between the parts of the object to resist the action of this external cause, and tries to restore the object from the deformed position to the pre-deformed position." The internal forces per unit area at a certain point of the cross-section under investigation are called stresses. Those perpendicular to the same cross-section are called normal stresses or normal stresses. ”

Xu Jingchang: What the hell is "......"? Is the bear child speaking official language?

Ting Fang spread his hands: "I'll give you a hint, the round dome is also called the dome." At the heart of the calculation is stress. How can you make such a big one not collapse? How do you calculate the interaction between stones? The dome can be built larger than a square house, which should be used by the Qin Heavenly Prison. ”

The mother of Hou Jingrong, the wife of Hou Jiamu, the right hand of the Imperial Palace, frowned and said: "Such a big project is very laborious and costly, so let's change the topic." ”

Ting Fang stretched out a finger and shook it from side to side: "Fei Ye, Fei Ye!" If it is hard to repair, it will naturally be a waste of labor and money. However, if there is a famine and the victims gather in a certain place, they can organize the victims to build a project. It is also a food distribution for disaster relief, but it is the victims who benefit and the imperial court also benefits. The dome is not a stop dome, which has mastered the stress and can also be used for water conservancy. The disaster victim got food, and if he did a good job, he could make a small fortune or learn a craft, and he could return to his hometown in the future, not to mention, he always had to buy things when he got money, right? Tearing two feet of cloth and tailoring with his wife made the cloth house make money, and the woman who weaved the cloth made money, and the cotton planter made money. Cloth farms, weaving cloth, and cotton planting are all rich, and they buy gold and silverware, and then make furniture, and so on, how should the profits be calculated? ”

Mrs. Hou opened her mouth wide, unable to understand Ting Fang's logic at all.

The rest of the edicts shook their heads one after another: "It's not good, it's not good, the gentleman doesn't say anything." ”

Ting Fang laughed, pointed to his nose and said, "I'm a girl, not a gentleman." ”

Xu Jingchang: "......" hooligans!

Ting Fang said with a straight face: "A gentleman is not a man who does not say profit, and a gentleman loves money and takes it in the right way, isn't it a word of profit?" A gentleman talks about selfish interests for profit, but what about public interests? Self-cultivation Qi family rules the country and leveling the world, for the sake of the common people in the world, it is to open the mouth and shut up the money, can't it also leave a name in history? ”

The wives of civil officials: "......" is so reasonable, I can't refute it! Confucius said that benevolence loves others, if you start with benevolence, profit is naturally not only for profit, otherwise you will not scold Zilu for not being a thing.

The old lady hurriedly supported her granddaughter and said with a smile: "That's exactly what I said, all of you husbands and gentlemen are people who work hard for the world." said that the household department, in order not to keep the people from healthy, naturally has to be careful, lest it hurt the people's foundation if they don't calculate carefully. Everyone in the world is a gentleman who does not speak for profit, and if he doesn't say anything about it, isn't there no one in the household? The military department also has to move grain and grass, and there is no one left. ”

If there are too many women, they will crook the building, and they will be better than mathematics, and they will be stunned to the head of the gentleman. Tingfang is not here to be a gentleman, she has to establish the name of a scientist, and quickly twisted the topic back: "It's just a question, and we don't live in a stone house, even if we can build it, we don't want to build it." Aren't we more arithmetic? "In the concept of the Chinese people, the all-stone house is for the dead to live in, and the living should not be mixed.

Ting Fang's words were too out-of-class, and the edicts continued to be confused, and Yan Chunfang's mother, Jiang Shuren, went straight to the point: "Can Xu Shizi be counted?" ”

Xu Jingchang shook his head: "I'm afraid that there are few people in the world who can count." ”

Jiang Shuren asked Ting Fang again: "Will you count?" ”

Ting Fang said: "Naturally, it's boring to come up with a topic that I can't know." Not to mention the far, the waterwheel that the sisters played, few people would count. If you don't believe it, you just draw the appearance of the outside, and offer a reward for someone to do it. Ting Fang thought for a while and said, "That, it's not a plaything, I really understand, you can use the water to squeeze rice for oil, or you can drive a waterwheel with the power of a child to irrigate." In this way, even the women are not afraid to carry water and farm. ”

The old lady stood up suddenly: "Are you serious?" ”

Ting Fang said: "The theory is feasible, but I haven't tried it. The truth of the world is the same, there is only one, different uses have to be tried slowly, little by little changed, and then you can use it if you don't get it in your hands. It's like stir-frying, we all know that we need to put oil and salt, but some people make it delicious, and some people make it bad. I'm just talking about it now, and if I want to be a general, I have to have soldiers to train. "Natural science was not attractive in ancient times, and it was a good idea to develop practical technology first. Huang Daopo is famous through the ages, and if you want to be the originator of the mountain, you must have enough authority.

Xu Jingchang said solemnly: "If this statement is true, it must be worthy of the saint." ”

Ting Fang pouted and said, "I only talked about it on paper, if you don't see it is believing, you don't believe it." ”

"That's easy," Xu Jingchang said, "It's hard to say, you can build a waterwheel?" ”

Ting Fang smiled: "How can anyone call a girl to work?" Senior brother, you can think of it yourself. ”

Xu Jingchang paused and sighed: "Also, you are not a boy, or you really made it, but it is just to increase the handle." He urgently needs to make a splash, his father Dingguo Gong is very unkind to see him under the pillow wind of his stepmother for more than ten years, and his position as a son is all based on friendship with King Fu, and King Fu is the crown prince's person. However, without the blue eyes of the saint, Dingguo Gong has countless ways to abolish him. is not a mediocre person who can only ask for ancestral shade, but it should be his thing, and there is no reason to give it to others. But there is no reason in the world to force a woman to show her face, Ting Fang was already disturbed by rumors, and she really shouldn't be provoked again. After thinking about it for a while, he simply confessed to the public orders to the end, "Let the ladies laugh, and the younger generations are only shallow in learning, but they are not as good as the four girls." The younger generation admits defeat and is convinced. ”

Winning is winning, losing is losing, talent is not as good as people, and demeanor cannot be lost. Everyone was stunned by Ting Fang's bluffing, and they were embarrassed to blame Xu Jingchang for not being angry. The Duchess of Zhenguo smiled at the old lady and said, "She didn't say big things, I have opened my eyes today, and I didn't come in vain." In the future, I'm just afraid that I will come to see the excitement often, and the old lady must not dislike me. "The son of the Xu family is very polite, I wonder if my daughter can get along with him?

The old lady said: "If you can't even invite you, how dare you be suspicious?" In the end, it's all games," Bi said and pointed to Ting Fangdao, "She is a girl," and pointed to Xu Jingchang, "A prince, and then counting His Royal Highness King Fu, are all good people, neither need to worry about the affairs of the court, nor do they have to care about the livelihood of their wives and children, old and young families, and they can play together." Tell them to take care of the things outside, and we girls just have fun when they are idle. My granddaughter, I don't have any other skills, and I always have all kinds of tricks to entertain my relatives, and she won't let me down. ”

Xu Jingchang is half the grandson of the old lady, so it is not surprising to make a joke, but he can also entertain King Fu, which is very domineering. The Yan family's serious Yue family talked about King Fu and wanted to talk about the monarch and ministers first, the Ye family and the royal family, are they so close here?
