"It's still so boring!" After the meeting, Shechtman, who was somewhat familiar with Junxin, complained.

"Isn't that normal?" Jun Xin looked at the uncle who was more than twice his age with a smile, and said, "Isn't the focus of the conference on the discussion and speeches after the first day?" Otherwise, what would you do by bringing together hundreds of scientists in the same field? Just have a meeting? ”

"That's right!" Shechtman nodded in agreement.

Junxin looked at his watch and said: "The meeting lasted a little longer, two and a half hours have passed, it's time to go to lunch, the organizing committee has prepared food in the hall, do you want to eat some?" ”

"Of course."

A large-scale academic exchange activity is never only about academic exchanges, the morning conference is a proof, the first 30 minutes of the meeting are nonsense, all kinds of thanks to thank and go, a little patience of Junxin is almost grinded and finally entered the topic.

First of all, I reviewed the history of crystallography, which Junxin listened to with relish, after all, Junxin did not know this knowledge very well. Shechtman, on the other hand, was not interested, and apparently he was not very interested in these things that he was already familiar with.

After what Shechtman saw as a long list of nonsense, he summarized the development of various branches of crystallography. After summarizing, it is the prospect of the development of crystallography, which is the most concerned by Junxin. Because this is a bit like the Hilbert problem, unfortunately the vision of the conference is still limited to crystalline matter. Later crystallographic associations, however, included the most rapidly developing and hotly discussed amorphous substances.

When these questions are said and done, it is time to eat. It was only then that Shechtman had that conversation with Junxin.

Junxin took a little beef and fruit according to his preference, and then brought the plate to a remote corner. To be honest, he feels very depressed in this circle, after all, the people standing in front of him are people who are one or two circles older than him, and there are not a few people who are three or four circles older than him. It's as if he and Shechtman were together, discussing innocuous little issues that never entered into academic discussions.

After eating quickly, Junxin came to classroom 0522 where he gave a speech very early. It can be seen that the organizers take good care of him, although the classroom is on the fifth floor, but the classroom is relatively large, Junxin visually inspected it, it is a standard classroom of 120 people. In a typical small-class school like Europe and the United States, it is not so easy to find such a large classroom.

"Mr. Junxin, are you here?" The first person I saw when I entered the door was naturally Jennifer, who had been waiting here for a long time. After she had copied one hundred and fifty copies of Junxin's lecture and bound it to the table at the door, she went to have an early lunch, and then waited in the classroom.

"Thank you!" Jun Xin flipped through the transcript of the speech he asked for a copy and said, "The speech starts at two o'clock in the afternoon, and there are still two hours to go, if there are other things, you can go and get busy first!" ”

"No, sir!" Jennifer rejected Junxin's kindness, then held up the copy in her hand and said, "I'm looking at your research results!" ”

"That's fine, if there's anything unclear you can ask me, there just doesn't happen to be anything right now, so I just have time to answer." Junxin still has a good impression of this girl who is good at seizing opportunities and is diligent and motivated, so he took this opportunity to give her a little more help.

"Thank you, sir!" Jennifer was overjoyed, and then quickly took the copy in her hand, Junxin glanced at it, and found that it was densely marked, and then Jennifer pointed out one of them and began to ask her own questions.

………

"Danielle, do you have any ideas, afternoon? I mean, is there anything you'd like to know this afternoon? Shechtman was eating when a man in his forties patted him on the shoulder and asked.

Shechtman didn't even have to turn his head to know who it was, so he said calmly: "Jones, you know, there is no specific goal yet, but there is no talk for everyone this afternoon, so I will probably go around like everyone else, and then decide who to listen to." ”

Jones had already sat down as he spoke, he and Shechtman had a good relationship, they were both associate professors at Johns Hopkins University, and they had subject connections with each other, so they were not as restrained as everyone else after they met.

"HOW DID YOUR EXPERIMENT GO WITH THE ARTICLE IN NATURE THAT THE PROFESSOR ASKED YOU TO REPEAT?"

"Ah, the repeated experiments of the article have been largely completed, and the results are the same as the author's results, and the errors are within the allowable range of instrumental errors. However, his predictive experiment has not yet been completed, and for the time being, it is only a verification of the quasicrystals of the metal complex of copper, iron and zinc, although it has not been completely completed, but according to the progress of the experiment, it is probably not wrong. Shechtman said solemnly, "One of the purposes of this visit to the International Union of Crystallography is to communicate with Xinjun, and I feel that his research in this area has gone a long way, and we cannot surpass it in a short period of time." ”

"Is quasicrystallization your goal in coming to the Federation this time?"

"You know, the professor recently gave me this work, and it is imperative to repeat the experiment, there are some things that I don't quite understand yet, and finding the author to ask is the quickest way." Shechtman said helplessly.

"That's just right," said Professor Jones, looking at a note full of things in his hand, "there's a report on the discovery of quasicrystals in the afternoon, so you can check it out." The location is in Room 22 on the fifth floor, and the time is 2 p.m.

"How do you know?" Shechtman asked in surprise. The organizing committee only informed the timetable of each branch society and the time of each scientist's presentation, and there was no information left. If you want to know research reports in your area of interest, you must attend various exchange sessions in order to obtain information. Professor Xiang Jones knew at once that there was really no report on today's speech.

"Hehe, it's not a big deal, I just asked the volunteers who helped me to keep an eye on the people who went to the copy office, and I immediately made this information sheet."

"It's a really good idea, but 0522 seems familiar, like I've heard it somewhere." Shechtman frowned and thought about it carefully, and suddenly said, "Oh, by the way, there is a strange teenager sitting next to me this morning, from a university in China, he said that there is a report at 0522 this afternoon, could it be him?" ”

"Did he say his name was?" Jones asked curiously.

"He said his name was Junxin, and I always felt familiar with the name."

"Leave him alone, won't it be clear when the time comes?" Professor Jones said, shaking his head.

"Yes, but while there is still a little time, let's take a look at the research results of other colleagues first!"

"Let's go!"
