Future library

People were coming and going outside the official residence of the royal star warlock.

Just transporting paper and ink every day requires two large trucks and five or six workers, and countless other experimental materials come in and out here. If there are large pieces of equipment, it will often affect the traffic in Miyagi City. Some court ministers have long suggested that the imperial star warlock's official residence should be located farther away, but His Majesty the Emperor has not approved any of them. After many years of development, the material flow of the official residence is now almost equal to that of the royal chef.

Cheng Jinzhou walked slowly into it and found that there was nothing magical about the so-called "Royal Palace". Perhaps the building was too old, the location was sensitive and was not conducive to repairs, so it was not as beautiful as the Star Warlock Association's building, but what appeared in it was Star Warlocks tend to be of high quality, and there are very many with one star or above. Unlike in the association, it is rare for a first-level Star Warlock to have a one-star title.

Xi Wuyong proudly introduced to Cheng Jinzhou: "Since Jiang Huangxing Warlock came to power, he has emphasized the importance of star warlocks many times. Our work has also been praised by the Western Star Warlocks Association. In the past 30 years, There are at least 15% more star warlocks in the entire Great Xia Dynasty who have successfully advanced."

When the numbers are small, using percentages is much more impressive, and the senior gentlemen understand the essence of this.

Cheng Jinzhou smiled nonchalantly and followed him as he walked: "A wise man doesn't speak secretly. You also know that the current situation of the Cheng family is not good. If possible, I want to develop in multiple directions so that I can be successful in the officialdom." Don’t waste the Star Warlock’s opportunity.”

The relationship between the two parties can only be described as acquaintance, and Xi Wuyong would not explain to him the importance of concentration as Xiang Xin and others did. Instead, he said with ulterior motives: "To talk about the closeness of the star warlocks to the officialdom, Jiang Huang Star Warlocks are respected, so you made the right choice by choosing the Royal Star Warlocks side."

"It's not about choice, it's just cooperation. My idea is, if you have any projects that you need me to do, leave it to me to complete, and then I'll hand it over to you. That's the best." Cheng Jinzhou was extremely unwilling to be labeled as a faction. Labels are cumbersome and useless.

Xi Wuyong curled his lips disdainfully. He felt that Cheng Jinzhou could only complete some work relatively well under the guidance of a senior star warlock. Moreover, without the star array, it was difficult to judge the efficiency. As for working independently, he didn't believe in it at all.

However, from his point of view, it was enough to bring Cheng Jinzhou. He did not need to consider how to distribute the work, so he still took him to the front of the studio with a smile and said: "Warlock Jiang Huangxing is very busy today, but I still ask to talk to you in person, but only for half an hour.”

Cheng Jinzhou shrugged and nodded again. In fact, he was a little nervous. He talked about calculus that day. Although the gentlemen at the scene appreciated it, they quickly lost interest. This is not to say that calculus has no value. It is just that ordinary star warlocks cannot see the value. Since Jiang Huangxing warlock has studied it At this point, his knowledge must be extraordinary. Dr. Cheng Da had to consider whether he could succeed if he wanted not to reveal even a little bit of it and also hoped to gain benefits.

Warlock Jiang Huangxing has a slightly fatter body, and his face has expanded, looking a bit like a graffiti version of a face with Chinese characters, and he has a double chin when he smiles. Xi Wuyong looked at Cheng Jinzhou with some jealousy, whispered, "Master's time is very tight," and then left. He hadn't seen such a smile in months when he was talking to his master.

"Sit down, let's talk slowly, don't be in a hurry." Jiang Huang stretched his body, poured the tea from the teapot on the table into two cups, and said with a smile: "I have been doing calculations since I got up in the morning, even with the star array. , as you get older, even if you eat well, you can’t make up for it.”

Cheng Jinzhou didn't expect such a cordial meeting. He squirmed a little uncomfortably and said with a smile, "It's not a coincidence that you invited me several times..."

"It doesn't matter." Jiang Huang interrupted him and said with a smile: "We are discussing between star warlocks. I know that my title of royal star warlock has attracted the attention of many people, but for me, at most Ten years is the deadline, and I want to take advantage of the last bit of time to really study something I want to study."

He patted the place where the certification stone was placed on his waist and said meaningfully: "When I was young, I struggled for contribution points. Speaking of which, I contributed myself to the Star Warlock Association. Now, I want to do something of my own. Something happened."

As he spoke, he took a sip of tea and said relaxedly: "Tell me what you think about limits. Last time, Warlock An Fengxing asked me a very pointed question, saying that infinitesimal quantities are sometimes seen. If the work is 0, can we make appointments with each other sometimes?"

0 cannot be used as a dividend, so only numbers that are not zero can approximate each other. Newton got this problem wrong at that time, which caused great doubts about calculus. If it were not for the subsequent mathematicians, from the basic aspect If it is improved, the entire system may be abandoned by the academic community.

The last time the two fourth-level star warlocks discussed this issue, Cheng Jinzhou was not present, and he did not have the opportunity to see the relevant meeting minutes. Now that he heard it at first, he couldn't help but break out in cold sweat. It is indeed not easy to get food from the fourth-level star warlock.

The problem of infinitesimal quantities is extremely complex to solve theoretically, and it does not affect the application of calculus. The main job of later generations of mathematicians is actually to explain why this thing can be used as pocket money or not, just like exploring why Thai ladyboys can be used as men and women - in fact, they really need to be used. Get up, if you want to be a man, you can use it like a man, if you want to be a woman, you can use it like a woman. As for why, you don’t have to worry so much.

Cheng Jinzhou couldn't remember how the gentlemen of those days finally dealt with infinitesimal problems. It might be easier to explain it with modern knowledge, but he would definitely not be able to solve it with the knowledge that the astrologers understood. Thinking that he was drunk a few months ago, what he was actually talking about was the problem of curves and limits, so he said in this regard: "When I was thinking about this problem, I actually wanted to accurately calculate the land problem. I think the curve can be regarded as a points, then a graph composed of a curve, no matter how twisted it is, can eventually be expressed as countless very, very small rectangles. Add their areas, and the result is the area of ​​the curve. In this way, as long as the points of division are controlled The quantity can determine the accuracy of the curve area..."

What he was talking about was the embryonic stage of calculus. Jiang Huang had already passed this research stage, but he still listened carefully, even though he had already understood most of it through the mouths of others. If not, Jiang Huang would not be able to judge the value of Cheng Jinzhou.

Jiang Huang didn't interrupt, Cheng Jinzhou said happily. Xi Wuyong had shown him some relevant information earlier. Although there was no detailed content, Cheng Jinzhou could tell which stage they had reached or where they had taken a detour based on the title alone - all graduate students in science and engineering, My major may not be very good, but calculus in mathematics is definitely well understood. This is the difference between the national unified examination and independent enrollment.

The scheduled 30 minutes have been talked about for 2 hours and it has not ended yet. In the primary stage of calculus, there were too many things to talk about. Cheng Jinzhou randomly selected two aspects: curves and limit processing, and could go on and on. What was especially rare was that Jiang Huang was willing to listen.

What they are doing is the work of blind men and elephants, and they can come up with similar answers, but they are not comprehensive after all. If they can use 2 hours, save 2 months or even more time, and have more horizontal understanding, what reason does Jiang Huang have? Don't waste hours.

During this period, Xi Wuyong gave him hot water once and was kicked out. Deng Zhu gave him a whiteboard and quill but was still kicked out. It wasn't until the two of them got hungry that Cheng Jinzhou stopped with a dry mouth. He taught a class for freshmen back then, and the simpler the calculus, the more he knew. He spent two or three hours discussing mathematical problems, but he couldn't tell much, but Jiang Huang still listened with great interest.

After all, mathematical problems are cumbersome to discuss and painful to study. The balance of an equation may take a certain gentleman several months or even years. From beginning to end, it only takes dozens of minutes at most.

Jiang Huang became interested and simply ignored things like lunch and asked someone to bring in two boxes of snacks. He apologized and asked Cheng Jinzhou, "Shall we continue?"

His snacks were put on the table, and Cheng Jinzhou could only nod. In fact, he was happy in his heart. There were so many small problems surrounding calculus. As long as the core issues were not involved, he was happy to show off for a while and make a good deal with Jiang Huang. The royal star warlock is much better than the so-called minister of Dali Temple. Even in the imperial title sequence, he is still a standard first-level civil servant. It is nothing to send some mathematical content, not to mention that Xi Wuyong has already hinted , can help him in the imperial examination.

While thinking, Jiang Huang's Chinese-character face completely rounded into a smile, like a disfigured picture of a graffiti spray-painted too close to the wall. He held a pen and scratched on the cardboard: "What we are studying recently is the issue of continuity, the curve of Continuity also affects the interval. What do you think of the relationship?"

Once he got close to the core issue, Cheng Jinzhou did not give a direct answer and said in a circle: "I haven't thought much about this aspect, but as far as the curve issue is concerned, the discontinuity is the main issue..."

Another afternoon passed for this conversation. Not only Deng Zhu and Xi Wuyong were anxious about waiting, but also the other star warlocks who cooperated with Jiang Huang's work found it difficult to continue. But on the other hand, their curiosity about Cheng Jinzhou also skyrocketed.

In any case, Warlock Jiang Huangxing will not waste time on ordinary people. They cannot carve star formations, and they are a one-star warlock, but they can talk to Warlock Jiang Huangxing for a whole day. They definitely don't have such a person. seen.

The studio of the Star Warlocks is more like a spacious painting room with no seats. Whiteboards are placed randomly inside. When the Star Warlocks go in and out in twos and threes, they fill up a whiteboard and then ask their Star Warlock apprentices to put it away. Since there are no computers, the astromancers, who are good at calculations, are solely responsible for solving numerical problems.

Warlock Jiang Huangxing's room is not only connected to the reception room outside, but also connected to several studios. Xi Wuyong looked at the wooden door here from time to time, wondering what he was thinking.

After a long time, Xi Wuyong sighed to Deng Zhu who was reading silently and said, "Maybe we will have a junior brother again."

"Then you have to agree." Deng didn't even raise his eyelids.
