Tan Ying and Bai Pi went all the way to the east, and only then did they have a little time to look at the market.

Xianjing, as the capital of the Qin Dynasty, has many workshops in addition to military and political institutions and various museums.

Although still confined to the handicraft industry, most of the workshops were only for the production of daily necessities, but this was also the core of the Qin state's revitalization since the collapse of Qin Zhaoxianggong.

Unlike the Six Kingdoms, Qin has always followed the route of a centralized military empire since the reform of the law, placing strict laws and using strong organizational power to create hegemony.

To a large extent, the people have survived by the sense of honor of a military power.

But as Guangwu called a halt to the civil war, the chariot of the Qin State was forced to stop, the army was deprived of enemies, and the people lost their goals.

Fortunately, King Xuewang saw the prosperity of Wang Ji, turned the rudder in time, and vigorously promoted the Mohists in Qin, especially supporting inventions and handicrafts, which made the Qin State great again.

But Xuewang is a Xuewang after all, although he is greedy for the production capacity of the Mohists, he has always been wary of the Mohist ideas, especially the political ideas.

After all, compared with the Legalists who are dedicated to the king, the Mo family was born in the people.

In the most glorious era, the sons of the Mo family also participated extensively in politics for a time, traversed the Seven Kingdoms, and even reached a strict organization across the borders of the princes, becoming a brotherhood-like existence above a country.

The Mo family giants even responded to the call, reaching a level that made the princes and kings jealous.

King Qin Hui may be able to accept such a person to manage the country, but the king of learning is absolutely unbearable.

What's more, isn't the best tool for suppressing the Mo family right in front of you?

As a result, under his appointment and unspoken rules, only the Legalists who were loyal to the monarch could become the mainstream of Qin's political circles, and the upper limit of the Mohists' participation in politics was extremely low.

Over time, the wolf-like ink writers with political demands naturally left the Qin State, leaving only a group of amiable ink practitioners like Fan Ya, who pursued the truth of heaven and produced inventions.

The Mohist Academy is the cradle of cultivating ink scholars and a treasure trove of knowledge.

From the opening lecture to the invention certification, the Mojia Academy has almost become a combination of a junior college + patent office.

Because of this, the collection of mathematics and science here is more complete than that of the Xue Palace.

Tan Ying and Bai Pi traveled all the way east until four o'clock in the morning, and finally stood in front of the open courtyard of the Mo Xue Museum.

Compared with the elegance of the small courtyard and the middle hall of the Confucian Pavilion, the Ink Pavilion is more like a majestic large institution, and people come and go from time to time.

The main brick building is two stories high, and along the perimeter is a circle of bungalows, which I don't know if it is for storage or for experiments.

As for the center of the square in the courtyard, there is a stone statue of Mo Zhai that is several people high.

Seeing such an ink pavilion, Tan Ying was overjoyed.

This is the National Academy of Engineering!

Even if it is just a Xianjing branch, the Mo family is so prosperous.

This prosperous world is exactly what I wanted!

In front of the courtyard gate, the two porters saw that the two of them were carrying the waist card of the school palace, and they only paid tribute from afar.

Bai Pi pushed this and entered the museum in parallel with Tan Ying: "The Mojia School Museum is the most open, and people in the school palace can enter and leave freely regardless of their home affairs." ”

"What about the others?" Tan Ying looked left and right and asked, "I can see that there are a lot of people entering." ”

"Mostly inkers."

"But I see there are still children?"

"That's the students who came to class."

"What about the dirty people?"

"That's the owner or the master, who should be here to exchange problems." Bai Pi said with a smile, "Many of the things we usually use are taught by the Ink Pavilion and made by the workshop, and after a certain period of time, the craft spreads, and the Ink Pavilion has new improvements, and their biggest benefit is here." ”

The two stepped into the main building while talking and laughing, and after Tan Ying handed Fan Ya's letter to the welcome guests, she stopped and waited with Bai Pi.

Tan Ying didn't know the content of the letter, but she only saw that the cover was written [Fan Pavilion Master personally opened].

When Tan Ying saw this title, she naturally asked a question: "I'm afraid that the hall owner is not a relative of Fanzi?" ”

"yes, don't you know?" Bai Pi looked around and said, "It's Fan Ya's granddaughter." ”

"Oh?" Tan Ying exclaimed, "That's not very young, is this appropriate?" ”

"People became famous at the age of ten, and you are also from Xianjing, have you never heard of the name of a goddess?"

Tan Ying was shocked when she recalled it slightly: "God counts women...... It turned out to be her! In the past, the teachers in the school often talked about this god and counted women, saying that we were not as good as other people's four-year-olds after five or six years of study. ”

Bai Pi laughed: "This is the truth, only in terms of arithmetic, Si Ye is her level of thirteen or fourteen years old, not me said it nonsense, it was Si Ye who said it herself when she was studying the palace Dao election." ”

Tan Ying stood in awe: "That...... What realm is she now? ”

"She didn't get the truth."

"Why can't this be enlightened?"

"Probably, Dao's heart is broken...... Bai Pi pursed his lips and sighed:

"The last one like you who didn't know the sky and the earth was thick, and she was making a statement in Qin Xue Palace at the age of 16, it was her.

"It's just that she's not as lucky as you, and she doesn't know how to avoid the edge of the problem with ingenuity like you.

"She only knows mathematics and science, and she has no compromises.

"So in the end, she really came out lying down."

"This ...... Sacrificial wine is inevitable...... Alas......" Tan Ying smiled bitterly and shook her head.

"At that time, it was not this sacrificial wine, it was the previous sacrificial wine." Bai Pi sighed, "Wu Xiaozi." ”

"Wu Xiaozi?" Tan Ying exclaimed: "The Mo family giant? Is it the last sacrificial wine of the Qin Palace? He compares ...... More ruthless than Han Sun? ”

"High in the Sky"

"What is ruthless or not, of course the argument must be ruthless." Bai Pi patted Tan Ying and said, "The key is to be clear about your flaws, and retreat in the face of difficulties, just like when Si Ye insisted that the ground was disc-shaped, and you directly accepted defeat, if you stubbornly argued, you may not be able to support the later theories." ”

"I'm ashamed......" Tan Ying sighed bitterly, "I can make this argument, and I also worship the wisdom of the industry, and I am open-minded in sacrificing wine, if they insist on embarrassing me, my example will not explain anything." ”

"Hey." Bai Pi said with a smile, "Wu Xiaozi is the one who insists on embarrassing people, there is no doubt that he will not admit it if he dies." ”

"That's trouble......"

"It's not just trouble, such a person can't pay attention to him." Bai Pi hugged Tan Ying's shoulder and said, "You listen to me about this, when the time comes, don't care what bird road he points to in Fengtian, don't see that Wu Niaozi, say nothing and don't see anything." ”

"Well......" Tan Ying asked, "I just want to know what kind of theory this pavilion owner made at that time, which will be refuted like this." ”

Hearing this, Bai Pi hurriedly turned around and waved his hand: "I'm too lazy to know, math is not fun, and the trouble is dead." ”

"Then I'll ask her in person."

"Then you're afraid you're revealing other people's scars." Bai Pi shook his head and sighed, "After the defeat of the self-reliance theory, she left the school palace and entered the ink hall, and she never mentioned this matter again, and even Si Ye didn't dare to mention it. ”

"Then I'll find a chance to ask Si Ye." Tan Ying had no choice but to take care of herself, "It's better to do your own business first, don't add to the chaos." ”

……

Moxue Museum, southeast on the second floor, the main room of the museum.

The folding window is ajar, and the breeze is blowing.

It was supposed to be a comfortable scene.

But in the huge interior, there is a large circle of bookcases with a roof, which is densely packed with books and models, but it makes people very depressed.

Looking at the long table under the window in the middle, a gray-shirted woman was frowning, and from time to time she brushed her sideburns, as if she had encountered some difficult problem.

The woman's eyes seem to have some perseverance, but her appearance and posture are very soft and gentle, her hair accessories are refreshing, and she is at a young age, no matter how you look at it, a green shirt and white skirt are more suitable for her.

But she was dressed in a gray shirt, cut off exaggeration and beauty, and only sought simplicity and close to the people, no different from all inkers.

There is no doubt that this is Fan Ya's granddaughter, the owner of the Ink Pavilion, Fan Huashi.

While he was thinking, there was a knock on the door.

She lowered her head and said "um", and saw a young woman in a blue shirt rub into the room.

"Pavilion master, there are two people from the Academy Palace looking for you." Nüshu Zuo respectfully presented the letter and said, "It should be entrusted by the secretary of the palace." ”

Fan was overjoyed when he saw the handwriting, but he didn't want his subordinates to see his thin appearance, so he only slowly opened the envelope and patiently unfolded the letter.

【When drawing:

[Recently, there have been a lot of variables in the school palace, and I am afraid that I will not have time to leave the palace.

[You must have heard of Tan Ying's affairs, Fengtian is about to guide the way, I will entrust him to you, let him stay in the ink museum for a while, read the collection, and write books, so as to respond to Fengtian.

[Tan Ying's identity is special, remember not to make it public, let him see as few people as possible, and for the rest of the security matters, Bai Pi will set up a formation to protect it.

[The next page is the question of this time——]

Fan was originally stunned when he painted, but when he saw the word "inscription", he didn't feel a trace of expectation, and quickly turned the page-

[A zongzi sells for 1 baht, and after eating, you can get 1 zongzi leaf, and 2 zongzi leaves can be exchanged for a new zongzi.

[I have 20 baht, how many zongzi can I eat at most?] 】

Seeing this question, Fan only sighed tastelessly, and then lit it to the left of the book: "Grandpa must be too busy, and he is perfunctory with this kind of question to coax children." ”

Nushu Zuo took the paper and read it, and the more she tasted it, the more panicked she became: "The owner of the museum...... This is not something that ordinary children can solve......

"How much do you understand?"

"It's not 30 anyway...... The curator will allow me to do the math......" Shuzuo said, and he raised his head and began to calculate.

"Let's go back and count slowly, the answer is 39." Fan Hua received the letter and asked, "Has anyone solved the question that was hung up last decade?" ”

"Nope." Shuzuo said dumbly, "The hall master's question is too difficult. ”

"Then let's put this on." Fan picked up the bamboo pen as he spoke, changed it on the basis of Fan Ya's original question, and pushed it to the left of the book, "Copy it on a large piece of paper and hang it out before closing, giving everyone a simple opportunity, otherwise no one can solve this question every ten years, and it will be boring over time." ”

The left side of the book took the new question and looked at it, and immediately shuddered.

[A zongzi sells for 3 baht, and after eating, you can get 1 zongzi leaf, and 5 zongzi leaves can be exchanged for a new zongzi.

[I have 1,234,500 baht, how many zongzi can I eat at most?] 】

(All the places related to mathematics are actually used in the number symbol system of this world, which will not be repeated later)

"Pavilion master, just by looking at this question, my brain is already messed up." The left side of the book only received a new question, shaking his head, "Whoever likes to understand it, let's solve it." ”

"It's very simple, you can find the trick at a glance, and the computing power of a ten-year-old child is enough to solve it." Fan Huashi said, nodded his forehead for a while, and then wrote down a number on the paper-

【493800】

"The hall owner is out of this?" Shuzuo opened his mouth and asked, "Is this the standard correct answer?" ”

"It's a standard wrong answer." Fan Huashi casually put his pen and said, "Such a simple question, I guess many people will calculate this as soon as they see it, tell them that it is wrong, go home and finish the calculation and answer it tomorrow, don't waste paper." ”

After that, she lowered her head and looked at the drawings on the eucalyptus: "Those two guests of the Academy want to use the library, and they are only allowed to enter and exit the library during this time." Or if you have to stay for a while, you can arrange a reception, remember to keep a low profile, and don't let the people in the museum know. ”

Shuzuo nodded in response, but asked again: "Entrusted by the company, those two seem to have identities too, don't you want to see the hall owner?" ”

Fan painted tastelessly: "Everyone does their own thing, it's better not to see each other if there is no need." ”

Shuzuo was unwilling, and stepped forward and asked: "Recently, I heard that someone in the Xue Palace has made a decision to sit on the throne, I guess, these two people may be related to this matter?" ”

Hearing the word "Theory", Fan Huashi's figure trembled slightly, and after a moment of distraction, he only said suddenly: "It has nothing to do with it, foreign scholars please read the Mojia Collection." ”

"Oh......" Shuzuo asked again, "Does the curator know the content of the specific thesis?" A lot of people are asking if it has anything to do with me. ”

"I don't know, I don't ask, I don't want to." Fan Huashi also shook his head again, "It's good that I do some routine work in the ink museum, and it's not our business to ask the heavens for the Tao." ”

Shuzuo didn't dare to say anything more, so he just took the order and left.

Back in the lobby, he led the two of them all the way to the library inside.

Tan Ying didn't care, but Bai Pi swaggered and asked, "Heh, my identity is not qualified, and the owner of the pavilion doesn't come out to see him?" ”

Shuzuo hurriedly explained: "The owner of the museum is busy with official business, and he is entertaining guests, apologize, apologize." ”

"Busy? Hospitality? Bai Pi squinted and said, "How did I hear that she only needs a few moments a day to deal with official business, and if she can't see customers, she can't see customers, and she spends all day pouring mathematical problems, work drawings and other things?" ”

"Ha ......" Shuzuo had to laugh dryly.

Tan Ying laughed at it: "It's wonderful, it's useless politeness when you see it, and it's wonderful if you don't see it." ”

"Ha ......" Shuzuo laughed a little more dryly.

Indeed, the temperament of the hall owner, you will only be more uncomfortable when you see it.

Entering the library, Tan Ying threw herself into the Mo family's bookshelf, and in a moment she picked up many mathematical and physical books, and brought them to the table with the Theory of Heaven.

Bai Pi completed the formation in two moments, and after a short instruction, he also left in a hurry.

In the next time, this ocean of knowledge belongs to Tan Ying alone!

Let's start with the math.

Since the beginning of the Dao, after a hundred years of development, a large number of mathematical tools have come into being, no wonder the industry can be so prosperous.

It's just that all kinds of mathematical tools exist in the way of "XX Calculations", and the content is also born from solving practical problems, and there is a lack of systematic connection with each other, and there is also a lack of universal conventions and a consistent system, which makes it very difficult to use.

It's very practical, it's not worth it.

But it's not a big problem, just integrate everything you need first.

As for physics, it has also made great progress, but the form of knowledge is also the same as mathematics, more for the service of engineering, most of which are like the "XX Classic" and "XX Record", which lack systematic combing.

Among them, there are many expressions of classical mechanics, and there are many specific formulas, but there are mixed among them, some are still being discussed, and some have been publicly recognized.

The larger project is to find out the "Star Classic" of many predecessors and the astronomical observation data of many years, and calculate and verify it.

In this way, near noon, hundreds of books have been moved to the table by Tan Ying.

Looking at these, Tan Ying was both panicked and refreshed.

The panic is that his major is not astronomy, and it may take a long time to find enough evidence from the ephemeris and then use the existing mathematical knowledge to verify the theory, and it may not even be possible.

Coolly, this thing is doable!

All the conditions for the verification of the theory are in front of you.

Next, you only need to use your brain, recall, learn and understand, as long as you have enough time, you may really be able to sort out a set of astronomical theories that the Mo family giants can't raise.

Let's start learning about the movement of the earth from the beginning today!
