Future library

All capitalists in the universe are carved from the same mold, no matter what prefix they are attached to - bureaucratic capitalist, national capitalist, civilian capitalist, white terror capitalist, red capitalist, blue capitalist, green capitalist, cuckold capitalist, or the Star Alliance Libraries - their essence is the same, pursuing profit.

Obtaining 10% profit in 10 days is a good thing that most capitalists would drool with envy.

Cheng Jinzhou looked at the customer service 010 that appeared in front of him with the eyes of an exploited person. His lips moved and he said, "Are you so aggressive in collecting debts?"

"That's where the responsibility lies." Customer Service 010 said with an awe-inspiring expression.

"Your rank in the library is definitely not high." Cheng Jinzhou Nunu said: "I still need you to rush for such a small order, just like a temporary worker in a bank."

Customer Service 010 made a "hum" sound and disappeared from the ring without a trace.

Xiang Xin heard the movement behind her, turned around and said with a smile: "Why, can't you sit still?"

"No, there are some ideas that can be understood more deeply after reading them." Cheng Jinzhou chuckled twice.

"If you have any ideas, write them down and send them to the association for a try. Not everyone has the opportunity to submit their results to the Star Warlock Association." Liu Kuang turned his back to him, his voice a little dull.

Cheng Jinzhou laughed twice and said, "It's not that easy to write."

"The calculus you mentioned is very good." Liu Kuang said calmly.

Cheng Jinzhou's face was startled. He hid it in the book without revealing it. Science that is very common in the 21st century is the high technology of this era. If all the contents of calculus were leaked, it would be nothing like martial arts secrets appearing in the world. There is a difference. But to think about it from another way, analytic geometry at the same time as calculus has begun preliminary research, but the astrologers have not actively moved towards calculus. This has a great relationship with its demand and use. In practical applications, in addition to design Apart from star arrays, the use of star arrays requires temporary calculations and judgments by astrologers. Naturally, the simpler the formulas, the better. Therefore, tools such as analytic geometry will be quickly developed, while calculus only attracts the attention of a few people.

If there was no such thing as measuring the land, Warlock Liu Kuangxing might have forgotten about it. There are so many ideological branches in mathematics. If you want to learn the same thing after seeing it, you will die from exhaustion. Moreover, many ideas need to be derived and developed from generation to generation. It is more likely that a kind of mathematics Tools are created, and only one or two hundred years later are they actually used and show their value. Of course, any correct mathematical idea is worthy of praise. In the 21st century, if someone can create a branch of mathematics alone, then regardless of whether it is widely used, this gentleman is qualified to become a national academician. In this era, Astromancers will only be taken more seriously.

Cheng Jinzhou would not tell others about calculus. It would be too scary and would only make things worse. Perhaps there is a greater chance that he would not be understood by other star warlocks and thus be isolated. Thinking like this, he naturally adjusted his facial expression and said: "I only have some preliminary ideas, mainly from the limits, because limits are often difficult to deal with in calculations, so..."

The beginning of calculus is the limit problem. Cheng Jinzhou deliberately said a few words, but there was not much substance.

"A very good research direction." Liu Kuang commented and focused on his own work. He, Wang Linghe and Xiang Xin formed an organic team, led by him, while the other two completed detailed work, somewhat similar to later project teams. Once he got to work, he had to take care of the other two people and had no time to chat with Cheng Jinzhou.

Every astrologer is a genius and hard-working. Just genius or just hard-working cannot become a high-level astrologer. Just like being ordinary and hard-working does not help to become an excellent scientist, there are always hard-working people in the world. Geniuses always have more efficient scientists, and there are always people who reach the top first.

Science and sports share the same cruelty and are never subject to human will, and mathematics is like the 100-meter race in sports.

Xiang Xin held the quill in hand without stopping. She had already focused her attack on geometry. As a star warlock, this was indeed a very good choice. Her interest in other mathematical content dropped sharply.

In fact, the Star Alliance Association has a variety of materials for people to consult and study, and the fees are not high. Liu Kuang and others just did not realize that calculus is not a small branch of mathematics, nor did they realize that Cheng Jinzhou did not only understand one Click.

Who really thought that a 13-year-old boy would know something that even the immortal Star Warlock didn't understand? The superiors always have no time to fantasize.

Two servants brought hot water back and forth. After the good green tea had been brewed four times, it would naturally be replaced with new tea. On the small table in the courtyard, there were both small desserts and soft salty snacks. In front of Lu Xu There is also a whole piece of roasted pork, cut into square pieces as long as your thumb and as wide as your thumb, which looks very tempting.

Drinking tea and eating meat at eight or nine o'clock in the evening is a life that people with weak stomachs cannot enjoy. Cheng Jinzhou ate stuffed foods such as spring rolls sleepily, and crossed his legs to watch Lu Xu gnaw the meat like a wolf.

On average, it only takes three to five seconds for this guy to eat a piece of meat. He can easily finish a plate of meat in three minutes, and his speed does not slow down even after eating three plates. When he finishes eating the last piece of meat, another servant comes forward and brings a piece of meat. A big pot of tea was brought to him. Lu Xu quickly wiped his mouth clean with a cloth, then fell down with a gurgling sound, like a worker on the dock, without the aristocratic temperament of a star warlock at all. With his fighting power after dinner, he is indeed an abnormal person to overeat like this.

After burping, Lu Xu lay back comfortably, glanced sideways at Cheng Jinzhou who was staring at him and said, "Do you like eating meat?"

"good."

"I've finished eating." Lu Xu said and continued to burp, stroking his few remaining hairs with his hands to soothe the pain of the Mediterranean Sea.

Cheng Jinzhou raised his eyebrows. He was finally familiar with Lu Xu's style and asked, "Do you know where I can buy Star Warlock materials?"

"Shaonan doesn't know, ask the guy named Wu to ask." Lu Xu replied carelessly.

"Then what do you do with the materials you usually use?"

"I only use two kinds of star array materials, and I have a lot of them in stock." Lu Xu lay on his back on the chair, about to fall asleep, like a strong domestic wild boar. If it weren't for the star array on his body, he might have become the most normal The knight.

It was Wang Linghe who finished a whiteboard, turned around and said, "What materials do you want to buy?"

Cheng Jinzhou said calmly: "I want to board the airship the day after tomorrow, so I am going to buy some materials for making a scale. You know, I am still quite interested in this aspect. I want to take a look at it during my free time."

The results that Xiang Xin submitted to the Star Alliance Association were mainly about the calculation of the attenuation ratio of the scale, etc., which is not surprising. Of course, what attracted Cheng Jinzhou was the price of the balance, which was a good loan repayment product.

"I still have some here, you can use it first." Wang Linghe said and wrote a list on the white paper, handed it to Cheng Jinzhou and said, "Can you see what else needs to be added?"

From weights to straight wood, bolts, dial hands, etc., although they are not uncommon in the 21st century, they are definitely valuable in a world lacking standardization. Cheng Jinzhou was a little embarrassed. He was going to make balances to make money and pay off debts. How could he be embarrassed to take other people's materials, especially when Wang Linghe was always kind to him.

Wang Linghe was a very straightforward person. He waved his hand and sat down. He picked up the tea and drank it relaxedly. A servant came to take the order and ran to the small courtyard next door.

Cheng Jinzhou shrugged. It was time for money, so he no longer pretended to shirk it.

After a while, two knight attendants came in carrying a box. Both of them were not wearing armor. Their bodies were strong and their muscles were bulging. When they placed the box on the ground, it made a heavy impact.

"It's not a good thing." Lu Xu cursed, stretched out his right hand, lifted the box to his side while lying down, opened it and said in a joking voice: "What do you want Mr. Cheng to do?"

"An ordinary physical balance." Cheng Jinzhou twitched the corner of his mouth. Naturally, he had to make real objects to make money. Intellectual property rights and other things should be slowly understood after he learned more about the world.

Lu Xu stood up with tea in his arms, waved the knight attendants to leave, and shouted at the same time: "Send more meat."

Then, he looked at Cheng Jinzhou and said, "I'm free, let's watch you do it."

Cheng Jinzhou couldn't stop him. He frowned and moved the chair to the box, holding the trouble on his forehead, and looked at each item one by one. Xiang Xin made the balance last time, and it was really difficult for him to make a high-precision balance that met the requirements.

Looking at the sky, he asked: "What time do you usually rest?"

"Star Warlocks usually rest after 12 o'clock." Xiang Xin seemed to have finished part of the content, and took a breath and said: "We all use 24 hours a day to facilitate communication with the Star Warlocks in the temple. "

The so-called astrologers in the temple are usually astrologers from the Far West, as well as astrologers who received education from the Far West. They spread Western culture and also passed on astrology. In the Great Xia Dynasty, most of them existed as priests and priests. , Liu Kuang and others are localized star warlocks. The latter is actively connected with the Star Warlock Association, and the former is often through the Holy Church in the far west. Although the two parties are different, they are also related to each other. Perhaps because of their small number, there is not much conflict of interest and the relationship is maintained very well.

It was probably eight or nine o'clock at most. Seeing that Liu Kuang was still in the thinking stage, Cheng Jinzhou called a servant and said, "Go to Mr. Wu Zong and invite him here. Say it's me who invited him."

If you have poor hands-on skills, you will need to use more labor.

After Cheng Jinzhou finished his instructions, he directed people to clear out a tabletop and use it as an experimental table. Then he took out the items in the wooden box one by one and placed them according to their types. Although these materials are neat, they are not arranged according to the requirements for making the balance, so there is always inconvenience.

After a few casual jokes, Xiang Xin once again plunged into intense calculations. Cheng Jinzhou was quite accustomed to doing his own thing. Not to mention how many classmates and teachers did this in his postgraduate studies, even his parents always did it. The situation of leaving his son behind to pursue his career. Therefore, although no one really came to greet him, Dr. Cheng Da looked at ease.

Niaoyu: I strongly recommend it. I hope to have good results and good performance. I hope everyone can vote for this book, and Shitori will definitely work harder.
