"Well, I prefer geometry and I'm not good at calculus and the like. The old priest blushed.

Zhao Dagui felt a little balanced at this time.

"I was able to dabble in the knowledge of calculus when I met a foreigner who gave me a book three months ago, but I didn't expect my colleagues in Shanghai to have already studied it in depth. Sheldon looked at Zhao Dagui and said eagerly.

"I just learned some superficial knowledge from Brother Xie, and I don't even count as an entry. Yang Willy said with a smile.

"Have you ever heard of Mr. Qiu Su from Zhejiang, who has a deep understanding of calculus and is currently translating a book on calculus and wants to use it as a teaching material to teach students.

If you have time, you can go to Shanghai to have a look. Zhao Dagui immediately said the words of invitation.

"Uncle Ren is going to do such a big thing? That's right, Uncle Ren's cone technique is the closest to calculus in China, and he has to do it. Sheldon clapped his hands, seeming very interested.

Li Xinlan's name is quite useful in the Western academic circle, although Li Xinlan is a native of Zhejiang and has never been to Guangdong, but the scholars here still have a considerable understanding of Li Xinlan's doctrine and have a very high opinion of him.

Zhao Dagui took the opportunity to mention the matter of the Oriental School of Science, introduced its faculty system and salary system, as well as the convenience of research, etc., focusing on describing that it was the best base for scholars of the Western School to study and study, and at the same time warmly invited them to work in the School of Oriental Science.

"With the knowledge of two people, it should be no problem to be a professor.

We, the latest mathematicians, study mathematics together, disseminate science and technology, and save the country with practical learning, why not be happy? Zhao Dagui strongly invited.

"Brother Zhao turned out to be the head of an academy, and he was disrespectful. Xie Yang and the others didn't necessarily have much respect for a college far away in Shanghai, but they couldn't help but be quite moved when they heard that Li Xinlan was actually teaching in that college, and the treatment of the college was also very good.

Most scholars who enter the Western academic circle generally have a good family situation, and they can support them to devote themselves to studying and studying the strange knowledge that they can't be officials in these eight lifetimes, but there are few people who are really rich and noble.

Moreover, most of these Westerners consume food at home and have no income, and they usually interact with the same Westerners, but they are rejected and despised by the mainstream Confucian scholars.

It would be perfect if there was a college dedicated to spreading Western studies, where you could read a lot of foreign science and technology books, communicate with like-minded people, and earn some money to support your family.

"It would be a good thing if we could go to the school that Mr. Ren ran and increase our knowledge together.

It's just that we just have something very important here, can we go back in a few months?" Then Sheldon had a yearning on his face, but he didn't know what he thought, and his face suddenly became more difficult.

"You can go anywhere, if you don't have two of you, I have a thin industry in Shanghai, as long as you two go to Shanghai, you will definitely be well entertained."

By the way, I don't know what is difficult for Brother Xie, can you say it, let me wait and consider whether I can help?" Zhao Dagui couldn't help but be overjoyed when he heard that Sheltun was willing to go to Shanghai.

Just these two people can calculus, they belong to the object of inevitable wooing, not to mention that they only learn calculus for three months, and they have reached the current level, this learning ability is also a first-class student in modern times, at least Tsinghua University and Peking University are no problem, they must be attracted to Shanghai.

"I just said that three months ago a foreigner gave me a book on calculus, and this thing is about this foreigner. Sheldon cleared his throat and began to speak of his business.

It turned out that Sheldon's family lived in Mong-Ha County, which was very famous in the Western academic circles of Guangdong, and also had a good relationship with many foreigners and missionaries in Macao.

Three months ago, by chance, a missionary introduced him to a Western diplomat, but not British, but American.

The diplomat, who is said to be a professor of mathematics at Harvard University in the United States, met with Sheldon and talked about mathematics, and both were amazed by each other's mathematical abilities and talents.

However, Sheldon had not yet been exposed to calculus at the time, and only communicated about trigonometry, geometry, and number theory.

Eventually, the diplomat found out that Sheldon had not been exposed to calculus and felt very sorry, so he presented him with a book on calculus, and told him that the future of mathematics lay in calculus, and that he must study it carefully.

Sheldon had some English skills, but he finally read the book through, and then he fell into it and studied it every day to achieve a high level in just three months.

"This diplomat, Mr. of the American Republic, has a lot of Western science and technology books in his hands, with a wide variety and huge content, and I have been going to his place to read them when I have nothing to do recently.

I hope to stay here for a while longer, and then go to Shanghai after reading all those books, what do you think?" Sheldon said his own thing, but Zhao Dagui fell into deep thought.

This Sheldon can reach his current level by studying himself for three months alone, and in terms of mathematical talent alone, he is no worse than Li Xinlan, but an American diplomat suddenly appeared, and he is actually a professor of mathematics at Harvard, where did this come from.

I am familiar with history, and I have never heard of such a person in modern history, is it a liar like Wu Liguo, but can make a mathematician like Sheldon admire, this mathematical skill can at least not be faked.

"Our college is in Shanghai, so it's no problem for Brother Xie to go early or late. By the way, what do you call this American friend?" Zhao Dagui asked.

"His name is Caleb Gusheng, and it is said that he was sent by their emperor, well, the president, and what kind of agreement did he sign with the governor? Sheldon didn't know the depths and hurriedly said.

"Gu Sheng, it turned out to be Gu Sheng, an old bastard, an old liar. Zhao Dagui then remembered that there was really such a number one person in history, and suddenly realized that he shouted.

Historically, Gu Sheng was appointed by the President of the United States to China to establish diplomatic relations with the Qing government, and the US government gave him a fund of 40,000 yuan, as a result, he brought tens of thousands of scientific and technological books and gun models to China's waters, and also helped the United States obtain one-sided most-favored-nation treatment and consular jurisdiction.

Before Zhao Dagui crossed, some people on the Internet had been discussing what the content of these scientific and technological books brought by Gu Sheng was, if the Qing court could make reasonable use of these books, whether it could become strong quickly, and of course, some people thought that if there were people who could get these books, they would be able to quickly complete the initial accumulation of technology and the like.

However, judging from the historical records, the whereabouts of these books are very mysterious, and no one knows where they went, and there are also theories that the British sent spies to obtain these books and destroyed them, and there are also claims that these books were later brought to Hong Kong and became the collection of the Hong Kong Library.

"How can Brother Zhao scold people?" Sheldon was not happy when he heard this.

"Hehe, a momentary gaffe, forgive your sins!" Zhao Dagui apologized after a smile, comforted Sheldun, and said: "This Mr. Gu Sheng is really a character that I have been friends with for a long time, but he has always been on the same side.

Brother Xie is familiar with this gentleman, that's great, can you introduce me to meet him?"
