"It was a wonderful presentation, and I think it was a very successful presentation. Mr. Junxin, it is a pride for Penn to be able to share your latest research with Penn! ”

When the lecture was over, Professor Ham welcomed Junxin into his office and said happily.

"You've won the prize, Professor Ham!" Junxin smiled and said, "Superstring theory is not a theory created by me alone, it is a collection of the wisdom of Professor Witten, Professor Schwartz, Professor Candela, Professor Strominger and Dr. Horowitz, I just provide an idea!" ”

Junxin's humility has been sincerely appreciated by Professor Ham, in fact, Junxin now will give people a huge pressure wherever they are, especially in front of researchers in the same discipline and older people, and it will bring a huge pressure to others. Therefore, this also allows Junxin to maintain a humble attitude, so that it can communicate with other scientists on an equal footing.

"You're welcome!" Professor Ham also unconsciously paid tribute to Junxin, "I have also read the paper published in the Physical Review Letters in September, although I do not know much about some of the ideas and methods involved in it because of professional problems, but the Department of Physics at Penn has also done relevant discussions, and the solution of the graviton problem does make superstring theory more attractive, which is the fundamental reason why we agree with you to give a lecture on superstring theory at Penn." ”

Junxin nodded, but he didn't speak. He knew that Professor Ham wasn't going to invite him into his office just to compliment him, and he was in a hurry to get back to Princeton, so he didn't have much time to go around with Professor Ham.

"That's right!" Professor Ham is obviously not the kind of person who likes to compliment people, and after Junxin was silent, he quickly changed the topic to the meaning of the invitation, "I invite you to come to me now to tell you something, and I personally hope that you will agree!" ”

"You say!" Junxin made a gesture of please.

"A few days ago, Mr. Gu Yuxiu, a tenured professor of the Professors' Association and our predecessor of the School of Engineering, put forward a suggestion at the professors' meeting, he hopes that you can be a visiting scholar in the laboratory he once presided over - the Electrical and Mechanical Engineering Laboratory, I would like to ask for your opinion, do you have any questions or opinions?"

Junxin asked suspiciously: "A visiting scholar in a laboratory should not need the approval of the professors' association, isn't it possible for the person in charge of the laboratory to decide?" ”

Professor Ham nodded and said, "You are not wrong, but because you are a little different from everyone else, first of all, because you are a mathematician, or a part-time theoretical physicist and chemist, not the same as electrical mechanical engineering; The second point is that Professor Gu raised the issue that your treatment is not the same as that of other visiting scholars, that your treatment will be that of a laboratory director and a formal professor at Penn, and that you are still a student, of course, this is not a problem. In addition, Professor Gu suggested that you only need to provide some advice to the laboratory for your work, and you can do the rest for yourself. ”

"To be honest, we at Pennsylvania don't have a shortage of visiting scholars, on the contrary, there are a lot of visiting scholars who apply to Penn every year, but your treatment is unique. Not to mention the rest, the minimum requirements for visiting scholars we require are professors in the top 10% of universities in a country or the top 5% of postdoctoral fellows, and although you are capable enough, you are only an undergraduate student. ”

"Because of the special situation, it will be brought to the professors' meeting for discussion." Professor Ham said with a strange expression.

Junxin nodded, understanding Professor Ham's words: "So, is what you are proposing now a formal invitation?" ”

"Naturally, this is a decision that has been made by the consensus of the professors' council and the school management, and you can take it as a formal invitation!"

Junxin fell into deep thought. It stands to reason that even if Penn invites itself to be a visiting scholar, it should be in the Department of Mathematics or the Department of Physics and Chemistry. But Gu Lao's intervention allowed Junxin to enter the electrical and mechanical engineering laboratory, and there must be Gu Lao's thinking in it.

Although he only visited Gu Lao twice, according to all the news he learned about Gu Lao, Gu Lao should not be so bored that it was really as simple as just letting himself go to the laboratory he was in charge of as a visiting scholar, so there must be Gu Lao's intention in this.

Gu Lao once held the position of deputy minister of education of the Republic of China government, and was considered a high-ranking official of the Republic of China, knowing that he would have to return to his country after completing his exchange studies at Princeton, because of international transportation problems, he would not easily come to the United States, and let himself go to his laboratory, which is indeed a bit intriguing. But fortunately, seeing Professor Ham's appearance, he didn't seem to notice any special meaning of Gu Lao's actions, and just thought that this was a kind of care that the elders of the same nation wanted to take care of their outstanding juniors.

Junxin didn't think that Gu Lao had such a thought, if it was really just such an idea, then Gu Lao should know that following Junxin's original idea and providing appropriate help was the best way, so this was definitely not what Gu Lao meant.

After thinking about it, Junxin's own intersection with Gu Lao only stayed in the past two days, and the first meeting mainly discussed Junxin's studies and research issues. Gu Lao was obviously very satisfied with Junxin's work and research, and he didn't put forward any opinions, which was obviously not the case.

The second meeting was when Junxin described to Gu Lao the envisioned problem of computers and computer Internet networks. If not the first point, then it has something to do with this meeting.

Electronic computers and electrical and mechanical engineering do have a great connection, but Junxin clearly told Gu Lao that he would return to China after graduating from Princeton, and it was impossible to stay abroad. But Gu Lao still arranged it like this, and the things in it are really intriguing.

Considering Gu Lao's return to China to exert his influence and Junxin's own suggestions and qualifications, it is obvious that he cannot completely control the research projects of computer development and Internet networks by himself, but it is still necessary to enhance Junxin's influence. Obviously, Gu Lao is going to focus on the problem of the scientific research and working environment after returning to China.

Thinking of this, Junxin's eyes couldn't help but flash a trace of gratitude, and then he raised his head and nodded to Professor Ham and said, "It's my honor to accept the invitation of Penn!" ”

Professor Ham stood up, smiled and stretched out his hand, "Happy working together!" ”

"Well, happy cooperation!"
