What can I do in two days? Physicists may tell you that you are moving in three-dimensional space, along the axis of time, the fourth dimension. Chemists will tell you what chemical changes have occurred in your body over the course of two days as a result of your physical movements; Biologists will tell you that during these two days, the cells throughout your body are metabolized in constant growth, passage, and death.

But if you ask a mathematician what he can do in two days, he will answer something like this: "Two days is equal to 2 days, equal to 48 hours, equal to 2,880 minutes, equal to 172,800 seconds, how many brain cells die every second because of thinking, and then how many brain cells die can think about a problem on average." "Then he'll take the trouble to tell you how much I've done in the past two days while you're dumbfounded.

If you ask Junxin this question, then he will first talk to a ghost like you and tell you that he has been in the hotel room for the past two days thinking about what to do with the special report of the closing ceremony.

In fact, Junxin has also thought about several plans, what is high-spirited, what is far-sighted, what is diligent and hard-working, and what is the accumulation of thick and thin skyrocketing. But in the end, it was vetoed one by one by Junxin, who was still quite sober. That being said, these are unrealistic things. At least I don't have the aura to control that group of crystallographers of the grandparents. Even if you go to learn David Hilbert now, it is estimated that it will be a good thing not to be knocked out of power halfway through. After thinking about it, Junxin finally decided to write a speech honestly.

But no matter how you say it, you can be regarded as a young man, and young people have their own young people's hearts and styles, so Junxin's speech report still has a little bit of its own style.

In the past two days, Junxin only went to meet Professor Max Peruz once, and never walked out of the door of the hotel again, even if he had a meal, he asked the waiter to send it to the room or simply asked Director Zhang to bring him food. It took two days to finally complete the presentation.

The entire International Union of Crystallography lasted for 10 days, and the closing ceremony was held on August 24 at 9 a.m. on the 11th day. The meeting is expected to last about three hours, and after the meeting, all members will have a final banquet, and then they can go back to their respective universities, laboratories, research institutes, etc.

Of course, there are exceptions, and the University of Toronto, as one of the world's top universities, will naturally invite these scientists to come to the conference, and then take the opportunity to give several undergraduate-level lectures or academic lectures, etc., and those professors who have enough time and have no problems with the project at hand will always be happy to accept such invitations. This is also the reason why the University of Toronto is willing to cooperate with the International Federation of Crystallography to lend the venue, and there are so many first-class scholars who cannot usually be invited to give lectures, which is a great incentive and opportunity for these students in many cases. Perhaps one or two of these students will emerge and be recognized by these scientists, and it will be a great opportunity for them in their lives.

In fact, as far as Junxin knows, at least Ms. Hodgkin promised to give a lecture at the University of Toronto at the end of the month. As for Professor Watney, he will stay at the University of Toronto for a period of time after the conference because the conference is held at the University of Toronto, so he also agreed to the request to give an academic lecture at the University of Toronto.

In addition, Junxin also received a lecture invitation from the Department of Chemistry of the University of Toronto in the past two days, but although he knew that this kind of thing was hard to find, he considered that there were still many things to deal with next, and he also had to rush to Princeton University as soon as possible to go through the admission procedures. So in the end, Junxin politely declined the invitation of the University of Toronto.

However, even if he refused the invitation to speak at the University of Toronto, Junxin agreed to leave an article in the University of Toronto journal to discuss the follow-up research direction and future prospects of quasicrystals in detail under the repeated invitations of the other party.

Another thing to do is that I said in my independent achievement report speech that I would make a comprehensive and detailed "Crystallography Table" for crystals from the direction of group theory, so Junxin, who hid behind closed doors and closed doors, did not do nothing and kept thinking about the issue of the speech. In fact, the content of the speech was not a problem for him, he already had an idea, although it was a bit troublesome to organize, but it didn't take two days. Another important reason is to deal with these two things. The finishing work of the "Crystallographic Table" took Junxin a whole day.

Two days passed in a flash in the busy work, and when Junxin woke up from a full sleep on the morning of the 24th, the fatigue left by the two days of busy work was swept away.

After putting away the speech and other materials in hand, Junxin greeted Officer Zhang and walked towards the prepared auditorium. As for Laura Jennifer, who has been serving him, she has entered her laboratory because of breakthroughs in some research problems since Junxin finished his special report on the results. The continuity of the experiment made it impossible for him to spare time to serve Junxin after listening to the professor's report during the day. Fortunately, Junxin was already familiar with this place, so he didn't bother her.

After entering the auditorium, Junxin quickly found his place. The difference from before is that at the opening ceremony, Junxin was just an inconspicuous little person sitting below, but now Junxin's position has been arranged on the rostrum. This was Professor Kluger's suggestion – he believed that the theme of this year's IU was quasicrystals, and that the discoverer of quasicrystals should naturally sit on the podium, despite his surprisingly young age.

Before, everyone thought that Junxin was a middle-aged or elderly scholar who had undergone countless experiments, but in the end, it was only known that Junxin was just an eighteen-year-old boy, so the proposal to sit on the rostrum at the closing ceremony made the members of the conference have different opinions, but in the end, Professor Kluger's proposal was adopted with the majority support.

As time approached step by step, one scientist after another found their place and sat down. When the hands in the conference hall pointed to nine o'clock, the crisp sound of the bell reminded me that it was time for the International Union of Crystallography to enter the official end.
