In the history that Cheng Jinzhou is familiar with. Calculus was founded by two men - Newton and Leibniz.

Taking advantage of Apple, most Chinese students remembered Newton and left Leibniz aside.

But from a mathematical point of view, the two people are of equal value.

There are so many papers in the world, and apart from those published by himself, Cheng Jinzhou really can't remember many, but Leibniz's first article on calculus, "A Wonderful Type of Calculation for the Maximum and Minimum" , but he remembered the exact year: October 1684.

The paper, which is just a few pages long, is very much like a modern Chinese graduate student's paper. The content is vague, the theory is incomplete, and the arguments are not rich, but it has epoch-making significance.

Of course, the most memorable ones are the famous koans in history.

Newton published "Mathematical Principles of Natural Philosophy" three years later in 1687. In the first and second editions of this book, he wrote: "Ten years ago, after a discussion between me and the most outstanding geometer Leibniz, In the correspondence I showed that I already knew the method of determining maxima and minima, the method of making tangents and similar methods, but I concealed this method in the exchange of letters... This most eminent scientist replied wrote that he had discovered a similar method. He also described his method, which differed little from mine except in his wording and symbols."

But in the third edition and subsequent reprints, this passage was deleted. Therefore, although Newton studied earlier, Leibniz published the results earlier.

With the memory of the public case, Cheng Jinzhou easily bought the original version of the article from Buddha. As expected, the latter cannot interfere with the normal operation of the Covenant Library.

But Cheng Jinzhou could also tell that he didn't like himself. It's not like the former customer service state employees don't like it, but it's like the state civil servants hate it.

Classmate Xiao Cheng snorted coldly and ignored him.

In the 17th-century Great Xia, regardless of the existence of the warlock Jiang Huangxing, calculus has already had a tendency to have a blowout. The blowout in mathematics may be one month, one year, or ten years, no matter what It is said that the one who occupies the first place is always easy to reach higher.

Warlock Jiang Huangxing has been studying calculus for at least 10 years, but still cannot form a systematic theory. Cheng Jinzhou can only express regret to him.

The world of mathematics is a world of real competition.

You can't criticize the other party for taking a shortcut just because the inspiration occurred. For Cheng Jinzhou, he just had the ability to sustain the inspiration.

After submitting the results report, Cheng Jinzhou just wanted to take some time off when Shi Yan came over and told him to go home.

The Cheng family's outer residence in the capital was in short supply, and the conditions were not as good as those in the church. In addition, Cheng Jinzhou did not have to pay regular greetings every day, so Cheng Jinzhou was happy and unwilling to miss Shu. Now being asked to go back suddenly gives people a very bad feeling.

After returning home, Cheng's father was sitting upright on the main seat in the main hall. Cheng Yunxiang was sitting on the right side awkwardly. He twisted even more when Cheng Jinzhou entered the door.

"Did you ask your second brother to bring the money back?" Cheng Yun'an's voice was serious and serious, turning a blind eye to Cheng Jinzhou's star warlock robe.

"Yes." Cheng Jinzhou lowered his head deeply, knowing that someone had listened.

"The history of the Xia Dynasty has lasted for hundreds of years, and tens of millions of people have united as one..." Cheng's father started talking about history and the country. The central idea was that bribery should not be accepted, at least not openly. This lecture lasted an afternoon.

Cheng Jinzhou understood what he wanted to say and almost stopped listening. A group of court officials gave him money. If he accepted it, it would be a blatant bribery. If he didn't accept it, wouldn't His Majesty the Emperor suffer from nervous intestinal obstruction?

A star warlock has accumulated a lot of good reputation in the court. Besides being Wang Mang, what else can he do?

What's more, Cheng Jinzhou itself doesn't have a good reputation.

Cheng Yun'an started his tirade before he could take a sip of water after entering the door. Cheng's mother looked on, feeling distressed but speechless. In her opinion, her son knew how to send money to the family. That was because he had grown up. There was no need to react so violently. .

Speaking of which, Father Cheng is also a very interesting person. His idea of ​​"the people are more important than the king", specifically for Cheng Jinzhou, is that it is allowed to embezzle public funds and materials from the country; but it is not allowed to collect bribes from officials.

Cheng Yunxiang couldn't laugh or cry by the side, and he couldn't bother his third brother in educating his children - no matter how old Cheng Jinzhou was or how high his status was, Cheng Yun'an could still teach him a lesson.

With a literati-style tirade, Father Cheng could easily hold on for three to five hours if he didn't digress. He even drank tea in the middle, until he was hungry, and then he stopped and said, "Besides, I have something else to tell you. Sit down. Get off."

Cheng Jinzhou rubbed his sore legs and sat down quickly. He had just used the star array to reduce the gravity load, but because he was worried about floating, his legs always had to bear a certain amount of weight, and it still felt uncomfortable after a long time.

Cheng Yun'an coughed and said, "I'm going back to Jinchuan Road."

"Go back to Jinchuan?" Cheng Jinzhou was shocked. Although Cheng's father had already said that he wanted to leave the capital, it was somewhat beyond his expectation.

Level 10 officials are transferred. If you want to be the chief official of a state, you always have to wait for a position.

However, Shaonan was within Jinchuan Road, and Cheng Jinzhou couldn't help but ask, "Where is Jinzhou?"

"Nanling Zhizhou." Cheng Yun'an smiled slightly.

"Upgraded two levels in a row?" Cheng Jinzhou was so surprised that he couldn't close his mouth. Even if the trip to the capital was used as a gold plating, Cheng's father did it too quickly. Moreover, Nanling is the largest state in Jinzhou Road. Even though it is the seat of the Taoist government, it is still a great improvement.

According to his thoughts, he wouldn't be surprised if he went back exactly as he was. Being an official is not like playing house. You can just run away if you don't like it.

If they could really be that carefree, poets would not be frustrated.

"First, as the head of the Household and Warehouse Department, I will go on an inspection tour in other places, and then I can be transferred when I come back." Cheng Yun'an said, stroking his beard with his hand as if he was satisfied, while Cheng Yunxiang winked at him from behind.

Cheng Jinzhou knew that his feelings were different, so he just congratulated him and made his father laugh.

After dinner, Cheng Jinzhou pretended to see his second uncle off and then asked, "What's going on?"

"I added some conditions privately." Cheng Yunxiang said with a strange expression: "The Grand Duke of Heyi agreed to give you a Jieyuan, and then transferred the third brother back to Nanling to be the magistrate. In addition, Wu Shuangsheng took part in the compensation? As for inspections, it is a matter of official procedures."

In fact, the conditions were not imposed by him, but by the Princess of Italy. For him, the position of being the magistrate of Nanling was nothing more than drizzle. Moreover, the officials in the capital actually don't like Cheng Yun'an staying in the capital.

Cheng Jinzhou was indeed a little happy. It was better to give Cheng's father a real title than to argue with others in the capital, so he nodded and acquiesced.

As of today, Wu Shuangsheng and his fourth commander have been in the basement for a week. For nobles like them, they will probably be remembered for a lifetime.

"The amount of compensation is about 120,000 taels." Cheng Yunxiang coughed and said, "How?"

"No problem." Cheng Jinzhou didn't care about the unexpected windfall.
