There are still a few days before the conference starts, but Junxin did not do the preparation of his thesis, on the contrary, he did not do any preparatory work, but walked around the University of Toronto all day long.

There were not many Chinese students at the University of Toronto in the early 80s, and it could even be said that they were unique. However, Duoda and China are inextricably linked. Mr. Qian Weichang and Mr. Guo Yonghuai, famous scientists in our country and the fathers of two bombs and one satellite, were born in this university.

Professor Guo Yonghuai is a disciple of von Kármán, an authoritative research scientist in aerodynamics, and a brother of the famous scientist Mr. Qian Xuesen. After returning to China, Qian Xuesen served as the director of the Institute of Mechanics of the Chinese Academy of Sciences, and Professor Guo Yonghuai, who later returned to China, served as the deputy director of the Institute of Mechanics.

Professor Guo Yonghuai, the only martyr among the 23 founding fathers of the two bombs and one satellite, died in a plane crash on December 4, 1968, at the age of 59.

Mr. Guo Yonghuai is the only scientist in the two bombs and one satellite project, and he is the only scientist who participated in the three projects of the two bombs and one satellite at the same time, and after the news of the plane crash came out, Premier Zhou cried on the spot, which is enough to show his importance.

Mr. Qian Weichang's experience is similar to that of Mr. Guo Yonghuai, who studied at the University of Toronto in the same group of students, both studied aerodynamics under von Kármen, and both served as deputy directors of the Institute of Mechanics.

The difference is that after Mr. Qian Weichang returned to China, he served as the president, honorary president, professor, honorary professor and so on of many universities, and for Junxin, he once served as a professor and provost of Tsinghua University.

Junxin's chic in the past few days is quite envious and jealous to Director Zhang, who lives with him. On this day, after Junxin visited the entire seminary, Director Zhang couldn't hold back any longer: "I said, Junxin, you are accompanied by foreign beauties every day, but you must not make mistakes!" ”

"Making mistakes? What's wrong? "Junxin is a little inexplicable.

"The beauties of that capitalist country come to you every day, you don't have to be uncontrollable, you have to make mistakes." Director Zhang's face was solemn, which made Junxin feel a burst of amusement.

"How so?" Junxin shook his head and said, "It's just that I have a great interest in the university where Mr. Qian Wei and Mr. Guo Yonghuai used to be, and then let Ms. Jennifer take me on a tour." ”

"Is that the only way?" Director Zhang looked wary and disbelieving.

"Naturally, what do you think?" Junxin shook his head again and said, "I'm a person who has a girlfriend, how can it be like you think?" ”

"Then why is that Jennifer constantly looking for topics to talk to you?"

"This is already an international practice!" "Abroad is different from China, in which some research-based organizations generally set up the exchange venue in the university, and at this time, the host university will send students from its own school as hosts or volunteers, and they will get the opportunity to communicate with top experts in this field." In general, scholars will do their best to answer these students' questions in return for providing the school with space and services. ”

After a pause, Junxin said again: "When domestic research institutions hold meetings, it is more important to set up the meeting place in some big hotel and guest house, so that there is not only convenient accommodation and three meals, but also convenient services. However, this also often makes it difficult for domestic students to come into contact with those who are in the world, so as to get the opportunity to receive their guidance. ”

"Is that so?" Director Zhang didn't seem interested in what Junxin said, and asked with an expressionless face.

"Hah, it's funny!" Junxin was noncommittal to Director Zhang's expression, laughed and said, what are you doing with the people in the system? Summer insects can't talk about ice.

"The formal meeting will start in two days, and I'm going to have to prepare a little bit in the next two days, so don't bother me if there's nothing urgent." After speaking, Junxin closed the door of his room,

Although these two days are the time for the great scientists in crystallography to arrive one after another, for Junxin, he doesn't know anyone here, and he is not a person in this circle in the first place, so he has no interest in making friends. His family knows his own affairs, and his research level in crystallography is only a doctorate level at best, maybe it is very simple to point out a graduate student, but if you meet a scientist with cutting-edge research, it is really not enough to see, maybe once or twice can be used to communicate with future development trends, but after a long time, those stocks in the stomach will also run out. So Junxin simply didn't go out.

As for Laura Jennifer, a graduate student in the Department of Chemistry in St. George's District, she had already been informed of the itinerary of the two days by Junxin, and she happened to want to find a time to think about her future research direction because of Junxin's suggestions in the past two days, so after hearing the latest news from Junxin, although she was a little regretful, she also returned to her laboratory by the way and began to sort out the results of the two days.

As Junxin said, it is true that most of his suggestions come from the mathematical aspect, and many things, especially the structural aspects, are analyzed from a mathematical point of view. After all, articles published in top journals, for the sake of credibility, especially complete science and engineering subjects such as chemistry and physics, will have strict mathematical deductions and mathematical formulas. Junxin memorized these formulas more often, and in turn, began to re-derive the chemical meaning under the influence of Professor Chen.

Two days was just a blink of an eye for Junxin, and he couldn't even complete a complete study of a mathematical topic. However, these two days were busy and fulfilling for others, especially those in the chemistry department at the University of Toronto. With the arrival of the world's top chemists and crystallographers, the campus, which was originally a bit depressed due to the holidays, began to become lively. The arrival of academic masters one by one symbolizes the official opening of the International Union of Crystallography.

On August 14th, the 11th International Union of Crystallography (IU) General Assembly officially began.

And Junxin's closed door also opened at the same time on this day, and Junxin, who had not gone out for two days, looked a little haggard, but his restrained spirit made him look extraordinarily energetic.
