Of course, Ting Fang couldn't say that she was wearing it, so she had to say vaguely: "I'm not used to it, I don't remember the title of the book when I read it......"

Xu Jingchang burst out laughing, the little girl was cute. Nowadays, science is in power, and there are fewer and fewer people who can do mathematics. There were some famous masters in the previous dynasty, but the staff of this dynasty had to take the things of their predecessors. He couldn't find a teacher if he wanted to be serious, so he could only gather a few friends to get together in one place to "not do his job". I want him to be a prince of the world, and he doesn't need the imperial examination, what kind of "business" do you want! Being scolded all day long for being scheming, there is no trick or trick, but it depends on how the world's acres are calculated, and how the world's taxes are returned. If you take 10,000 steps back, you will settle the account, at least your own harvest will not be pitted. It's better to like arithmetic than to like fighting grasshoppers, right? Now it's more serious than him to fall to the fighting grasshopper! It just doesn't make sense.

Looking at Ting Fang's sparkling eyes, Xu Jingchang sympathized with another unlucky guy who wanted to enjoy the treatment of "not doing a job", and on the other hand, he felt that maybe the girl didn't need to do a job in the first place, and she could learn arithmetic recklessly. Otherwise, why is the little girl's arithmetic so powerful? It can be seen that her family does not restrain her. There was a trace of envy in my heart, and I was about to speak, but I suddenly remembered that the little girl still wanted to borrow books, so I explained first: "The book is not mine alone. ”

"Huh?"

Xu Jingchang's smile was slightly bitter: "I don't have that much money to buy." "It's not easy for the stepmother to mix things down, if she didn't do some business secretly, I'm afraid she would have to rub other people's books. I felt ironic in my heart, if it weren't for the stepmother's bent desire to let him learn badly, I am afraid that these indecent books would not be able to leave his house. Several friends couldn't be the masters at home, so they discussed that he would take the lead so that they would not be suspected. Recruit whoever provokes whom, this is! However, there is no need to elaborate on trivial matters, just say, "Western arithmetic books were bought with money from friends who love arithmetic, and I can't do it alone." If you want to borrow it, you might as well come up with a question and I'll show it to him. They can't do it, so they are naturally willing to borrow books from you. ”

Ting Fang nodded: "What you said makes sense!" "Since ancient times, there is no first martial arts, and the coolest thing about science monks is that if they encounter a fight, they can win or lose at a glance. Standing on the shoulders of giants, she was not afraid of her ancient math fans. There are many application questions, but if you can change it to the ancient version, you have to think about it. After a while, he said: "If you plate a layer of two centimeters of copper on an iron ball with a diameter of three inches, ask about the weight of copper." ”

Xu Jingchang: "......"

Ting Fang added: "The kind of Xuande furnace is used, and the twelve refined copper plates. ”

Xu Jingchang hates calculating irregular objects the most, and he can't think of any way to do it, and he can't find a clear answer in the book. Or if there is, he can't understand it. After all, it's self-taught, and if you don't understand it, you don't even have a place to ask. As soon as Ting Fang came up, he calculated the sphere and gritted his angry teeth: "Will you?" ”

Ting Fang paused for a moment: "You get me a Xuande furnace, I'll calculate the density first." "There are very short-answer questions in the differential calculus, and she has forgotten too much about the things in her previous life, so the basic questions can ensure that there are no mistakes. If a troublemaker stumps himself, he will be embarrassed, and he will not do anything less in his life; If you can't borrow a book, it's a big deal. Now that she is short of information books, it is not easy to restore the level of her previous life. When I think of this, I regret it immensely. It shouldn't have fallen in ancient times, ancient women lived so hard, and they even lost the guy who ate with a big heart. I'm really two, really!

"What is density?" Xu Jingchang said suspiciously, "Why do you keep saying strange words?" ”

Mother Hu coughed lightly, girl, you are about to reveal your stuffing! Busy said: "It's late, we should go back." ”

Where is Xu Jingchang willing to put it, and asked: "What is density?" ”

Ting Fang suddenly felt liver pain, is it really good to go straight from mathematics to physics? Again, you have to answer: "It's the weight of a thing at a certain age." For example, for an ingots of the same size, the weight of gold and silver is not the same. Isn't it the weight of the copper plating? If you don't explain the density, how do you calculate the weight? Refined copper is not the same weight as blister copper. ”

Xu Jingchang continued to ask: "How to calculate?" ”

Ting Fang said: "No tools. "At least basic equipment, alas. Vernier calipers existed in ancient times, but they seem to have been lost?

Xu Jingchang hurriedly said: "You say, I'll prepare." ”

Mother Hu coughed: "Girl......"

Xu Jingchang and Ting Fang fried their hair at the same time and lay down. Groove, why am she \ me a woman!

Ting Fang suppressed her anger at the ancient times and wrote down the method of calculating density on paper in a language that the ancients could understand. Not forgetting his original purpose, he translated the formula of how to find copper plating into Chinese, wrote it on another piece of paper, and pointed to the simple diagram: "Vernier caliper, make the container to want." I don't have it now, you can look for it. Really no custom-made, remember, to find an experienced master to do, the equipment as standard as possible, otherwise the slightest mistake is a thousand miles. Let's not joke about it. ”

Xu Jingchang was solemn and made a gesture to Ting Fang: "What my sister said is very true, I will do my best." ”

Ting Fang said with a smile: "Find a good master, don't introduce me to me." I have a cousin who doesn't like to study, and I don't know if these can sharpen his temperament. "It's hard to be the boss!

As soon as Hu's mother heard it, she knew that it was for Chen Gong, and her heart suddenly softened. It's for Chen Gong, but also for his wife's face. There is a nephew who is out of tune, although the concubine does not say it clearly, but the inadvertent disgust and frowning expressions of the masters still make the already attentive wife very sad. Thinking of his uncle's wife's plan, Hu's mother couldn't help frowning. As a young master, she can smile and say that the boy is very good; Being an uncle is not pleasing to the eye from beginning to end. Such a clever girl has suppressed all the men who are older than her, where is Chen Gong matched? No, she has to tell her wife, her uncle really wants to get married, can she have six girls and seven girls, why are she staring at her four girls!? It's almost the same as saying it to Brother Qian.

Xu Jingchang had never done a similar problem, and with the calculation of density, he suddenly felt that the door to a new world was opened. I can't let Tingfang become my sister immediately, so that I can take it home and talk about it at night. There is no need to mention the trivial things of introducing the master, and it is more convenient to make a set and give it to her. Suddenly it occurred to me that in addition to my sister-in-law who can take it back, there is another situation where I can? However, after looking Tingfang up and down, he wilted again. Girl film...... It's a few years older than you! A few years older, even if you go to Ye's house to splash and roll, you have to turn back! With such a small baby, I really can't do it......

Xu felt the deep malice from the world, and said weakly: "There are four masters of arithmetic in the Southern Song Dynasty, their books are all good, and I have some at home, but I can lend them to you." ”

Southern Song Da!? Chinese!? Ting Fang turned his head and asked the guy, "Do you have any?" ”

The guy duck listened to Lei for a long time, and finally it was his turn to understand the topic, and he almost burst into tears, and nodded busily: "Yes, yes, the four major families have it, and we also have it in the Ming Dynasty, Miss or?" ”

Ting Fang turned his head again and asked Xu Jingchang: "Report the title of the book." "It's all math books, so naturally there are good and bad things. She is lazy to flip through one by one, after all, it is ancient, and it is estimated that there are many people at the elementary school level, isn't it a waste of her reading time?

Xu Jingchang estimated Ting Fang's level, and really hid everything that was too simple, just reported that he found it difficult. There are still some little Jiujiu in her heart, for the sake of the recommendation, or if there is a problem that can be consulted, she will definitely be willing to answer. Unexpectedly, when he saw Ting Fang's gorgeous double bun, he felt that the whole person was not good, men and women were very defensive, how could he have more contact with the little girl? Why is she a girl? Alas, if he were a girl, he would have done it! The god-damn Cheng Zhu Lixue, it's not enough to pit arithmetic, and the men and women who are engaged in Mao are defensive! It is clear that in ancient times, the seven-year-old did not sit on the same stool, and the children over the age of seven could not sit on the same stool! Why is it that people over the age of seven can't meet casually now? It's really a black-hearted person who sees everything black! Like now that the girl is standing in the room, what does it matter! False seriousness! Mad Sickness!

Xu Jingchang complained frantically in his heart, his face was still not revealed, his heart was very congested, but he reported the title of the book in a calm tone. The guy didn't use a pen at all, he only heard it once and then re-reported it, and it was word for word, and he was also a talent!

After a while, the guy instructed his colleagues to carry books to the Ye family's carriage one by one, humming happily. Tingfang was also very happy, she had been stupid for nine years, but she didn't expect that it was possible to play mathematics in ancient times, but fortunately, it was not too late and she gained a lot. Only Xu Jingchang was very depressed, and he had already known that Ye Langzhong was his teacher, and Ye Bianxiu was separated by one layer in the end. Alas......

The Ye family's carriage gradually moved away, and Xu Jingchang's spiritual head followed. Asked the man to carry his book into the carriage, lowered his head and thought of the formula of the formula, and shook it back to his house.

On the carriage of the Ye family, Mother Hu said to Ting Fang angrily: "Be careful Xu Shizi suspects you." ”

Ting Fang smiled: "I'm afraid, he is suspicious, and if he is suspicious, he can only rot in his stomach." Whoever he says he talks to doesn't believe him. ”

"You left a word!"

Ting Fang said: "The pavilion style I wrote, there is really something to do, and I will pay the bill." Besides, who has nothing to do with it? And not taboo. I'm still a girl's family, and I'm good at writing poems and lyrics, and maybe I have some fame. "That'......s how China has gone from being the world's boss to being a deflated man that anyone can step on." In the past, I always thought that the Ming Dynasty had clearly seen the germ of capitalism, and if it were not for the Qing Dynasty to conquer the advanced civilization with backward civilization, perhaps we could unify the pace with the world. But when I looked carefully in ancient times, I found that the root root of the Ming and Qing dynasties had nothing to do with it, and the root was in the Ming and Song dynasties! The separation of imperial power, civil officials, and five officials was dismantled in the Song Dynasty, leaving only the struggle and compromise between imperial power and civil officials. Unless there is a military government, no matter who does it, inertia will make her more and more closed.

As it turned out, Tingfang's speculation was not bad, and it was the red regime that could eventually make China become the world's big man again. Because of her background, Tingfang didn't feel that life was sad, she just felt very lonely. In the era of backwater, even if you have fine clothes and food, you still feel very lonely. Because she is a girl, no matter how prosperous the world is, what does it have to do with her?
