"Oh, okay! Let us have Ms. Dorothy Crawford Hodgkin, a famous British crystallographer. ”

"Thank you!" Hodgkin stood up, although his voice was a little old, but after listening to the report for nearly four hours, his voice was still crisp and powerful, "My question can be regarded as a summary, the member of the presidium of the conference, Professor Watney from the School of Chemical Engineering of the Massachusetts Institute of Technology, and I asked me whether quasicrystallography is considered the category of crystallography, what do you think of this problem?" What's your answer? ”

As Junxin is full of confidence and answers the questions of various scientists from all over the world with ease, no one regards him as a discoverer of good luck. No one took him seriously either, even though he kept emphasizing that he was not a chemistry scholar, but no one really took that sentence seriously.

In fact, there will be some dirty things in the scientific community at any time, and jealousy and cold words can be regarded as light. It's not that Junxin hasn't suffered from these things. After the article on his discovery of quasicrystals came out, there were many people in various research institutes and university laboratories around the world who did not believe in it, and to this day, there are still many scientists who do not believe that quasicrystals really exist, and they have only one reason, that is, they do not conform to the laws of nature.

However, Junxin is not Shechtman, and after the discovery of quasicrystals, he suffered great repression and opposition, on the contrary, Junxin's papers are too detailed, including almost most of the quasicrystalline structure research and model construction, both complete mathematical derivation, rigorous model construction, and very accurate description of experimental phenomena. There are even extended conjectures and predictions, which make it impossible for everyone to object, although many still oppose it.

Before the International Union of Crystallography made such a thing as changing the theme of the conference, it must have gone through rigorous discussions, and finally changed the course of the conference, so as to change the theme to the current state, in a way, the weight of Junxin's article is too heavy.

As of the end of last month, it has been three or four months since his quasicrystalloid research paper was published, and according to the news released by the journal Nature, the number of citations of the quasicrystalline paper has exceeded 300, and it continues to grow. In a sense, the discovery and study of quasicrystals is beyond the comprehension of some people, and thus requires a conference to completely change the traditional view, and based on this, this conference gathered many masters, and the question raised by Hodgkin is a representative of their discussion of this issue.

However, even as the discoverer of quasicrystals, in fact, although Junxin's opinion is important, as the final decision-maker, Junxin's opinion is only a reference, but Hodgkin's question, in a sense, affirms Junxin's academic status. This is the biggest gain of Junxin today.

In fact, if Hodgkin really wanted to ask, then he could have asked at the beginning, but Hodgkin waited until the end to ask this question, which is enough to show how much she values Junxin.

In fact, Jun Xinke didn't think too much, just thought about it for a while, and then replied: "Well, although I don't think this question should be answered by me, but as the first person to study it, I would like to give a little reference!" ”

"When I discovered this substance, I thought about what to call it. At that time, when I was looking through various literature and reference books, I once saw the definition of crystal by the International Union of Crystallography, which is simply that a crystal is a long-range ordered periodic structure of matter, but quasicrystals do not have the concept of periodicity. To put it simply, according to the classical definition of crystallography, a quasicrystalline is not a crystal, but an amorphous substance. But from a structural point of view, it does have the characteristics of long-range order, which is why I named it quasi-crystal. ”

"But I think quasicrystals can also be counted as a type of crystal. Because both quasicrystals and crystals have strict Bragg diffraction patterns and have strict geometric properties. In fact, I think we can completely include quasicrystals in the new heading of aperiodic crystals, and divide crystals into periodic crystals and non-periodic crystals, and that's my answer. Obviously, Junxin's proposal was good, but he was a little impatient, but since he had never considered himself a chemist, he didn't have any scruples about speaking, and he said whatever came to mind.

As soon as Junxin's words fell, there was an uproar below. Which of these people is not a bigwig in the chemistry world, and they have been taught a lesson by a junior here, which is really a little unacceptable to them. Moreover, they had only just begun to take over the concept of quasi-crystals, and now they were about to accept the concept of a larger aperiodic crystal, and their thinking could not change for a while, and suddenly the entire lecture hall was in an uproar.

"Of course, there are still many days to the meeting, you can think about these issues for yourself, if you have any questions, you can come to me at any time in these days, thank you!"

After a pause, Junxin glanced at the watch in his hand, and then said: "I think I have taken up a lot of time today, the time is almost eighteen o'clock, ladies and gentlemen, the organizing committee has prepared a sumptuous dinner for us, I think we should solve the problem of dinner, how about it?" Thank you! ”

In any case, Junxin's report was still very successful, so when Junxin euphemistically announced the end of the report, people, whether they were against or in favor, stood up and applauded as a thank you to Junxin.

"Whew, it's finally over!" Jun Xin exhaled secretly, and kept explaining his research for four hours in a row, which made his energy and physical strength very exertional, although the temperature was adjusted by the air conditioner and did not appear to be overheated, but Jun Xin also deeply felt a burst of heat and exhaustion.
