Chapter 178 of the Science Fiction World Text of the Academic Master, fooling a big shot back to China to reach a consensus with Witten, and Pang Xuelin stayed in Princeton for a few more days.

In the past few days, Witten mainly explained his ideas on m theory to Pang Xuelin, while Pang Xuelin established a mathematical structural model of this theory through the Ponzi geometry method.

Although Pang Xuelin has seen the related concepts and ideas of m theory in the real world, he is not a theoretical physicist after all, and his accumulation in physics is far less profound than that of Witten.

Moreover, there must be some differences between the m theory re-established through Ponzi geometry and the m theory in the real world.

Therefore, in the past few days, Pang Xuelin has also taken out the relevant concepts of m theory in the real world to discuss with Edward Witten.

This surprised Witten.

Because many of the ideas that Pang Xuelin proposed coincided with what he thought of, some ideas even Witten himself had never thought of.

After several days of discussion, the two men sorted out their respective division of labor.

Witten is mainly responsible for theoretical work. He proposed a new idea, and then Pang Xuelin established the corresponding mathematical structure through Ponzi geometry, and then used mathematical calculation results to infer whether this theory is valid.

Since Pang Xuelin also had to participate in media activities and go to various universities to give reports, the two had to make an agreement to communicate once a week via email.

Fortunately, in this era, the United States has established a backbone Internet network between universities. In the academic world, the use of email has become a common phenomenon.

Therefore, Pang Xuelin doesn't have to worry about how to contact Witten in a short period of time.

The question is, how should Pang Xuelin contact after returning to China?

China's Internet will not be fully functionally connected to the international Internet until April 20, 1994, when NCFC passes the 64k dedicated line of the US Sprint Company.

Although China completed the first national email sending as early as 1986, currently only a small number of computers in China can be connected to foreign countries, mostly limited to a few units such as the Institute of Computer Science, Chinese Academy of Sciences, and whether it can complete email sending and receiving with Princeton University is also a problem.

"Pang, otherwise you will be able to achieve results in Princeton for the first half of the year, within half a year!"

In the cafe, Edward Witten, who was sitting opposite Pang Xuelin, suggested.

Pang Xuelin shook his head and smiled bitterly: "This is not possible. There are still a lot of things in our country? In addition, I brought my sister to the United States this time, and I can't stay in the United States by myself and let her go back alone."

Although it is interesting to create the M theory with Witten, Pang Xuelin did not forget his mission to enter this world.

The most important job you have to improve your education level in poor areas in the country.

Therefore, it is impossible for him to stay abroad for a long time.

Witten frowned and suddenly raised his head and said, "How about this, since you can't stay in the United States for a long time, then I'll just go to China. I'll find a teaching position in Shuimu or Peking University. In this way, we can guarantee the progress of the research?"

"Are you sure you want to go to China?"

Pang Xuelin was slightly stunned and a little surprised.

Witten smiled and said, "Where is going to be a research, I have a premonition that with your joining, our new theory will definitely shock the world!"

Pang Xuelin laughed and said, "Okay, then we will agree that we will return to China together when I complete my itinerary in the United States!"

"Then let's just say that!"

Witten raised the coffee cup and touched Pang Xuelin lightly, and the two looked at each other and smiled.

...

After having supper with Witten, Pang Xuelin returned to the hotel room and directly found Xie Yongxin, president of the Chinese Mathematics Association, and told him about Witten's idea of ​​going to China.

"What, Edward Witten is going to China?"

Xie Yongxin stood up from the sofa and said incrediblely.

Pang Xuelin smiled and said, "Yes, there is a topic that he needs to cooperate with me to study, and I can't stay abroad for a long time, so I have to let him come to China. This is what he proposed. I am not familiar with the key domestic scientific research units and I don't know which unit to contact."

Xie Yongxin looked at Pang Xuelin with a little dullness, and it took him a long time to recover.

In later generations, it was not uncommon for Fields Medal or Nobel Prize winners to come to China to work, but in this era, a Filipino award boss and a top theoretical physicist came to China to work was almost the only one.

Xie Yongxin said curiously: "Teacher Pang, Professor Weiteng cooperated with you to study what topics?"

Pang Xuelin said: "It is mainly in the superstring theory."

Xie Yongxin nodded and said, "If Professor Witten wants to go to China, I believe that no matter which unit you are welcome, the key is Teacher Pang, where are you going to work next? If you determine the unit well, then I think Professor Witten will definitely go to the same unit as you."

"I myself..."

Pang Xuelin lowered his head and began to ponder.

Pang Xuelin knew very well that after returning to China, it was basically unlikely that he would return to Lingziding Village and continue to serve as his primary school teacher.

Even if he has this intention, the country cannot allow it.

A mathematician with a Filipino award-winning tycoon level who can be a rural teacher and can be laughed to death internationally.

Then finding a suitable school or scientific research unit to appoint it has become an urgent issue that Pang Xuelin needs to consider.

Pang Xuelin pondered for a moment, raised his head and said, "President Xie, I am going to go to Tsinghua University."

"Why do you go to Tsinghua University? Peking University is the best majoring in mathematics and physics."

Xie Yongxin was slightly stunned.

Traditionally, whether it is mathematics or physics, Peking University was better than Tsinghua University in this era.

Historically, Peking University and Tsinghua University were both comprehensive universities, but in 1958, the colleges and universities were adjusted, and the science departments of the capital universities, mainly Tsinghua University, Peking University and Yenching University, were adjusted to Peking University; the engineering departments were adjusted to Tsinghua University.

Therefore, in the 40 years from 1960 to 2000, Peking University was the university with the highest comprehensive level of liberal arts and science in China, and Tsinghua University was the university with the highest comprehensive level of engineering.

Pang Xuelin smiled and said, "It is because Peking University's mathematics and physics majors are strong enough that we have been unable to use our skills in the past, so it is better to be comfortable to come to Tsinghua University."

Having said that, Pang Xuelin knew very well that the reason he chose Tsinghua was because Tsinghua's engineering background was more suitable for him to display his skills in the future.

In this regard, Xie Yongxin can only sigh at the talented and human nature.

With Pang Xuelin's current academic status, although he is not a crush on the domestic academic community, most people really have no choice but to deal with him.

Xie Yongxin smiled and said, "Okay, I happen to be familiar with Principal Luan Jing from Tsinghua University. Do you want me to say hello to you in advance?"
