Pang Xuelin shook his head helplessly.

Until now, he has been observing Tomoko's every move, trying to find a trace of artificial intelligence from her.

But I never discovered anything different from ordinary people.

Even from her, Pang Xuelin vaguely felt the existence of personality and personality.

Is the technology of the Three-Body Civilization really strong enough to create such a powerful artificial intelligence?

Or is it that Zhizi is just a strong artificial intelligence created by the system, or even a life with self-awareness?

Pang Xuelin didn't know.

But he vaguely felt that when Tomoko returns to him in the future, she might bring some different colors to her life.

...

Two days later, accompanied by Tao Zhexuan, Pang Xuelin went to San Antonio, Texas to attend the award ceremony of the American Mathematical Society's Cole Algebra Award.

At this award ceremony, many top scholars came to the mathematics community.

Such as Pierre Delinie, Peter Sanek, Manuel Balvaga, Vietnamese mathematician Wu Baozhu, Chinese mathematician Zhang Yitang, etc.

The prize is not too much, only 20,000 US dollars, but it is also another heavyweight award that Pang Xuelin won after the Millennium Award and ICCM Award.

At the dinner after the award ceremony, Pang Xuelin became the focus of the entire dinner.

After dealing with the congratulations from many scholars, Pang Xuelin turned around and saw a slightly fat Chinese scholar holding a glass of champagne and looking at him with a smile.

The person coming was Zhang Yitang.

In the Chinese mathematics community, Zhang Yitang should be considered a late-achieving mathematician with legendary experience.

Zhang Yitang was born in 1955 and studied at the 78th grade of Peking University in his early years. He was one of the most outstanding students at that time.

In 1985, after graduating from the Department of Mathematics at Peking University, Zhang Yitang went to Purdue University in the United States to pursue a doctorate degree.

Unfortunately, Zhang Yitang suffered eight lifetimes of bad luck and met Mo Zongjian, a doctoral supervisor who almost ruined his life.

Zhang Yitang's doctoral thesis that year announced that it proved the Jacques conjecture.

The Jacobi conjecture is also a difficult problem in the mathematics world, and Zhang Yitang was able to solve it at a young age, which caused a great sensation at that time.

Many media have reported that the mathematical skills in the paper are very high.

Unfortunately, the part that Zhang Yitang himself proved was impeccable, and the lemma cited his mentor was pointed out by many mathematicians to be wrong.

But his mentor just refused to admit it.

This is already very strange in the mathematics community.

What's even more terrifying is that as a mentor, Mo Zongjian slandered Zhang Yitang's personality because of this incident, and even did not want Zhang Yitang to graduate.

A PhD from Purdue University can graduate in three years, but it can’t graduate in more than seven years.

Zhang Yitang was dragged to the seventh year. Seeing that he could not finish his career, Zhang Yitang's life was about to be dragged down.

In the end, Pudu University was really unable to bear it anymore and organized other mathematics professors to read Zhang Yitang's paper. Everyone agreed that although the paper had errors (actually, it was Mo's fault, and Zhang Yitang could not be blamed at all). However, its level was very high and was enough to graduate, so it forced intervention to let Zhang Yitang graduate.

Even so, Mo Zongjian did not let Zhang Yitang go. Not only did he not give a letter of recommendation (not giving a letter of recommendation from his supervisor abroad often means that the students are misconduct or have major academic problems). This guy even used his influence in the academic world to make Zhang Yitang unable to find an academic job.

At the most downturn, Zhang Yitang could only work odd jobs in a restaurant to make a living, so he was in his fifties and had not yet started a family and had a career. He was alone, without a house, no car, and no stable income.

Until later, one of his younger brothers from Peking University who worked at Intel had a very rare math problem with computer algorithms. He found him. He spent three weeks in his spare time to solve it easily, so he obtained a very high-level patent.

So he was recommended to the University of New Hampshire as the lowest-level lecturer, which eliminated the embarrassment of continuing to make a living by serving dishes.

The core of the American academic community is the tenured teaching system, which is divided into three levels: assistant professor, associate professor and professor. These professor positions are scholars in the traditional sense, conducting both teaching activities and scientific research.

Once they have obtained tenured teaching positions, these professors can do whatever scientific research they want. Even if there is no funding, no progress in scientific research, and no longer scientific research, the school cannot fire them without a legitimate reason.

The lecturer is just a temporary teaching position, with heavy teaching tasks and no support in scientific research.

Under this circumstance, Zhang Yitang stayed in the position of lecturer at the University of New Hampshire for a full fourteen years.

Until 2013, Zhang Yitang finally made a big splash and published a proof of a weakened version of the twin prime number conjecture in the Mathematics Annual, proving that there are infinitely many pairs of prime numbers, with a difference of less than 70 million.

Although 70 million is a big number, if the result is true, it is the first time that someone has officially proved that there are infinite sets of prime pairs with spacing smaller than the fixed value.

This year, Zhang Yitang was fifty-eight years old.

In the mathematics community, it is hard to say that it is a feat that has never been around since then, but it is an unprecedented feat.

If it weren't for meeting Mo Zongjian, with Zhang Yitang's talent, he would be expected to become a top mathematical master of his generation.

"Hello, Professor Zhang!"

Pang Xuelin took the initiative to raise his glass and walked towards Zhang Yitang.

Zhang Yitang also raised his glass and smiled: "Professor Pang, congratulations!"

"Thanks!"

Pang Xuelin said with a smile.

Zhang Yitang said: "Professor Pang, do you have time after the dinner? I have a few questions about Ponzi geometry and I would like to ask you for advice!"

Pang Xuelin laughed and said, "Of course there is no problem. After we go back to the hotel later, I will go to the room to find you."

Zhang Yitang nodded and told Pang Xuelin about his room number.

Then, the two chatted for a while, and Zhang Yitang chose to say goodbye.

At this time, Delinie walked over with a glass of wine again.

"Professor Pang, you can't let it go this time. You'll finally come to the United States and come to Princeton to give a lecture."

Delinie smiled.

Pang Xuelin couldn't help but feel a little headache.

Delinie has invited him to Princeton to give a presentation many times. Pang Xuelin has been ruling several times on the grounds that there are too many domestic affairs.

This time when he came to the United States, he had promised several universities to give a report, and it was not appropriate to miss Princeton.

But now, Qi Xin is studying in Princeton, and Pang Xuelin goes to Princeton, and it is too deliberate if he doesn't go to find her.

After hesitating for a moment, Pang Xuelin nodded and agreed.

Even if you meet Qi Xin at that time, it will be no big deal if you meet as an old friend.

Pang Xuelin smiled and said, "Professor Delinie, okay, but I have agreed to the invitations from several other universities. If I go to Princeton, I will probably have to wait at least until the end of October."

Delinie smiled and said, "It's okay, we welcome you at any time."
