I handed in the sand sculpture through the book system

"Is your surname Zu?"

The dusty Wang Zhi said this calmly, and then reached out to wipe the sweat from his forehead.Before Mu Chen and others sent someone to invite him back, Wang Zhi was fighting to the death with a mountain of sundries in Tianyi Pavilion—the Northern Dynasty had been established for several generations, and the attic stored treasures that had been tributed by various places for hundreds of years, accumulating over time It was difficult to accept and inspect, and in the end it all became ashes.Now they have to wear protective clothing to clean up one by one, which is really laborious and arduous-maybe a piece of waste paper thrown around in the dust, after wiping and sorting, becomes a piece of amazingly famous handwriting.

However, the recent arrangement has been very effective, so Wang Zhi is in a good mood, and even patiently recalled the history of mathematics that he is not very familiar with for a while, and finally shook his head.

"The ancestral surname is not uncommon in the Southern and Northern Dynasties, so it may not be such a coincidence." Wang Zhi pondered: "Even if there is any connection with Zu Chongzhi, it is likely to be a grandchild or even a great-grandchild. Zu Chongzhi was from the Liu Song Dynasty in the Southern Dynasties. Characters, at least fifty years have passed since then..."

He looked back at Xiang Liang: "Is there any other news?"

Xiang Liang's face was calm, and he said lightly: "The official position is too small, and I can't find out anything now. I only heard that his ancestors were quite good at supervising machinery, so I rewarded him with such a position in the craftsman's supervisor."

Since entering Chang'an, Xiang Liang has been secretly planning to expand the intelligence network.But so far, the eyeliner is only limited to the upper echelons of King Qi's lineage, so naturally they can't inquire about it in such detail.

Wang Zhi snorted, but there was an expression of interest on his face.

"In this way, it is really accurate." He nodded and said: "Zu Chongzhi was in charge of supervising the manufacture of machinery, and the knowledge of pi should be figured out at this time. According to this statement, that is true. The origin of family education should not be underestimated..."

After Wang Zhi uttered the words "not to be underestimated" lightly, the expressions of everyone present changed slightly.The reason why they brought Wang Zhi from the search site of Tianyi Pavilion so quickly was not for him to appreciate the historical wonders, but because they were really afraid of this young man surnamed Zu.In the past few days, Bei Yan's financial operations on bonds have been dazzling and complicated, but to put it bluntly, they are nothing more than financial magic tricks that go back and forth; this kind of technology is easy to fool ordinary people, but if you really want to This kind of mathematical genius with sharp logical thinking and clear vision, playing this meaningless number game is basically asking for humiliation...

But the most important confidence in finance, if this small official surnamed Zu accidentally revealed some key information, that would be the thunder that could lift King Qi up to heaven.

As a result, there was silence in the room for a moment, and the few people around the table sat down together, but they were all thinking about how to deal with this inexplicable trouble.After all, Mu Chen was too young, and suddenly had a fluke attack, and couldn't help but say:

"Actually, after all, it's been more than 1000 years. He may not be able to recognize such a trendy - eh - technology..."

Hearing such a rather ignorant remark, Wang Zhi and Xiang Liang were still silent, but Bei Yan, who had grown up in the finance department and knew the cruel difference between talents in mathematics, couldn't help but sneered. Shaking his head again and again:

"You think too highly of me." He said calmly, "First, without the aid of a computer, my system design is very rough, with many loopholes; second, if this person is really a descendant of Zu Chongzhi, then as long as he He has half the talent of his ancestors, and these tricks are absolutely impossible to hide..."

Bei Yan paused for a while, but there was a bit of exclamation in his tone.

"...After all, Zu Chongzhi is a fierce man who can push the principles of calculus with his intuition—and both father and son are top experts. Hey, this level of mathematical intuition, this level of talent—"

Of course, in the highly developed field of modern mathematics, the mere principles of calculus may not be so inscrutable, even high school students can touch it in the exam.But this was in the Middle Ages 1000 years ago, when human understanding of mathematics was basically limited to addition, subtraction, multiplication, and division!Considering that the available mathematical tools are so crude and rough, what Zu Chongzhi achieved is basically equivalent to making a simple computer with a children's creative toolbox ordered from Taobao.Of course you can say that this thing is quite low-level, but considering the corresponding difficulty, it's probably best to have a little respect for the big guy behind it...

Bei Yan happens to be a person who is fairly knowledgeable in mathematics, so he is full of indescribable respect and fear for Zu Chongzhi, and even because of this fear, he also has a lot of respect for that official whose ancestral surname is not clear. Afraid——If this person really has the talent of the ancestors, he is so ordinary. If he really wants to let him master relatively high-end mathematical tools, then the system he designed is definitely not enough.

As for where the high-end math tools come from... Bei Yan's eyes wandered for a while, scanning the brand new books piled up on the wooden table.They wrote textbooks, on the one hand, to literacy for soldiers, but on the other hand, they were also trying to promote the diffusion and upgrading of mathematical knowledge; therefore, referring to many textbooks of later generations, they added a lot of rather difficult content such as function equations.These things are basically incomprehensible to anyone, so most of them are stored in the training camps for soldiers to be read at will.

As long as this official surnamed Zu pays a little bit of attention, it will not be difficult to get a textbook.Once a qualitative change occurs...

Because of such an estimate, Bei Yan broke his mouth decisively, advocating that this official surnamed Zu must not be underestimated, and must try to solve it.When he spoke, his tone was so decisive that Mu Chen was startled:

"solve?"

"I mean bring him to the front!" Bei Yan rolled his eyes and could only quickly explain: "Throwing such a person in this dilapidated yamen in the Middle Ages would be a waste of money and waste that cannot be tolerated. If he really has such a talent, of course we have to fight for it.”

Wang Zhi next to him was taken aback for a moment:

"Strive for—how to fight for it? Our current position is quite embarrassing, and it is not suitable for making big moves..."

"I didn't ask you to be appointed officials and give money or something..." Bei Yan sighed: "Forget me, my master's and doctoral supervisors are all from mathematics. There are too many mathematicians in China, and they understand the psychology of this type of people very well. To be honest, those who can study mathematics in the environment of the Middle Ages are really out of utilitarianism and purely out of love for academics. Such a person, the general method is not very useful."

After all, he smiled confidently.

·

Bei Yan's smile certainly had a reason.He rummaged through the materials brought by modern times several times, and finally found the crucial document, which was the "Elements of Geometry" after repeated proofreading and revision by experts based on Xu Guangqi's translation of the Ming Dynasty.

If you want to describe the significance of "Elementary Geometry", then one sentence is enough - after 1000 years after the birth of this book, human beings have not been able to surpass its achievements; There are as many as sand and sand, all of which are brilliant and eternal names in the annals of history.Such as Newton, such as Leibniz, such as Euler, such as Gauss, such as all the names that you can find in the theorems and formulas if you open an advanced mathematics textbook at will.

In Bei Yan's eyes, this long and frighteningly heavy list can be said to clearly and unmistakably point out the best use of "Elements of Geometry":

—Mathematician Trap.

·

For some ulterior reason, there were hundreds of brand new books in the soldier training camp outside the city, with weird terms and graphics everywhere.A few curious soldiers took the book and flipped through it, and quickly shunned and never dared to touch it again—"Geometry Elements" was originally a very advanced and obscure knowledge, plus Xu Guangqi's awkward use of words when translating Gu Ao, that is simply beyond the scope of normal people's comprehension.

But normal people can't understand it, but it doesn't mean that fierce people can't understand it.So under the deliberate connivance of the traversers, these stacked books were left unattended, and of course they were stolen by the eyeliners planted by the powerful.

While Mu Chen and others were sitting in the mansion, anxiously waiting for the trap to attract the big fish they dreamed of, Zhang Yao, who was stationed on the grassland, sent an extremely long telegram.

This telegram has tens of thousands of words, and the terminology mixed in it is complicated and extremely difficult. It is basically a research report on fungi by various biologists.After receiving it, the traversing team basically couldn't understand a single word, so they could only forward the telegram directly to Hyundai as required. On the one hand, it was to show Hyundai the results and report the situation;

Of course, Zhang Yao obviously knew the details of everyone in the traverser team.Therefore, after spending several hours transmitting the experiment report, she sent an additional short telegram, explaining the current progress of the laboratory concisely and to the point. .seven

"—to put it simply." Xiang Liang explained to Mu Chen: "After the results came out, Zhang Yao took some time every day to measure her weight, and she paid special attention to her figure—she had already figured out what to do at the National Technology Contribution Award Ceremony. The dress, it’s just that I can’t wear it very much now..."
