Chapter 216 People are leaving
After chatting with Mu Liangcai for a while, Xu Chuan said goodbye to the two of them and left alone.
In the villa apartment, Pan Deming sat opposite Mu Liangcai, with a smile on his face. He took a sip of tea and said, "It's good to go back to China. Professor Xu is a real genius."
On the opposite side, Mu Liangcai also smiled and said: "Yes, Professor Xu is a truly top scholar. For such a scholar, we will feel more at ease if he returns to China early. If we stay there, there will be too many surprises."
"If there were no other arrangements, we would have taken him back to China long ago."
Pan Deming smiled and said: "I don't know how far he can go in the future, but for now, he is still dedicated to learning."
After a pause, Mr. Pan sighed again and continued: "The domestic academic environment needs to be rectified. It is so bad that it is difficult to retain talents."
"It's time to change our previous ideas. We have a very unhealthy traditional thinking, which believes that intellectuals should live in poverty and live happily, and that scientific research funds should mainly be used to buy instruments and equipment, resulting in greater restrictions on labor fees for scientific researchers."< br>
"This kind of thinking is extremely harmful to the development of science. Compared with advocating sentiments, the real feasible way is to effectively improve the treatment of scientific researchers, especially the treatment of graduate students."
Opposite him, Mu Liangcai smiled but said nothing.
It’s not that they don’t know some things, but it’s just that it’s too difficult to change.
Many times, it's not that the country doesn't do something, but that it can't do it, or it requires a huge price to pay, which is not worth it in comparison.
Changes in the academic system and changes in scientific research all require money to support.
The country has no money. This is the biggest problem.
Don't look at China's GDP ranking second in the world, second only to the United States, but it is based on a large scale. Averaged out to each person, it falls directly out of fifty places.
The size is so big that any change would be a turmoil.
I want to change it, but it’s difficult.
If the boat is small, it is easy to turn around, but if the boat is big, it will take a long way.
But as long as the direction is right, it can always be done.
Xu Chuan didn't think that much. He actually didn't care much about the domestic academic environment now, or he didn't think that much.
What he wants now is just a cleaner academic environment in the country.
This is difficult for others to do, but it is not that difficult for him. When the country invites him, he makes a request and it is enough to say something to the superior.
Thinking about this, Xu Chuan stepped into the venue of the exchange conference, ready to find other mathematicians to exchange ideas.
This International Mathematics Congress is probably the last good opportunity.
If he missed it, he would have to wait another four years, and secondly, whether he can still go abroad for exchanges after four years is a question. After all, he is still a purely theoretical researcher, and all his results are basically public and available to every country. study.
After returning to China, he switched to applied sciences and began to study room-temperature superconducting materials and nanomaterials, which caused big trouble.
When the time comes that he wants to go out, people from above will be arranged to dissuade him.
But if it's difficult to go abroad, there might be a chance to organize an international mathematics conference in China, so that he doesn't need to go out.
And with his current ability, coupled with China's economic boom, the country's national strength has become much stronger, so there may not be any hope of accomplishing this.
At least in China, it is impossible for a thief to steal the medal of a Fields Medal winner at a mathematics conference.
This time at the International Mathematical Union, he may be able to use this point to promote it.
Although it is a little late to take action now, it must still be done. As a country with the second largest economy in the world, it has only hosted an International Mathematical Congress, which is too shabby.
However, it is also a troublesome thing to do. You have to contact some domestic and foreign mathematicians to join forces to promote it.
It would be difficult for him alone, even as a Philippine Award winner, to promote this matter.
"Forget it, let's communicate first. It's not urgent anyway. There won't be a meeting and voting until the second day after the end. There is still time to proceed."
Shaking his head, Xu Chuan walked into the exchange meeting venue to find other mathematicians to communicate with.
The afternoon passed quickly.
On August 2, the second day after the International Congress of Mathematicians, the mathematics exchange meeting officially opened.
Every four years, the International Mathematical Union invites a group of top mathematicians to give reports at the International Congress of Mathematicians.
This is not only their duty, but also an honor for mathematicians who go on stage to give reports.
Mathematicians who can be invited to give 45-minute or one-hour reports at conferences are top talents in each country.
Just like China, if you have the ability to give a forty-five-minute report at the International Mathematics Conference, you are eligible to apply for the Yangtze River Scholars; if you are able to give a one-hour report, you are even eligible to apply for the National Academician.
Of course, at the International Congress of Mathematicians, in addition to the one-hour report and the forty-five-minute report that start at a fixed time, there is also a ten-minute report for general scholars.
Any scholar who participates in this mathematics lecture can apply to the International Mathematical Union for a ten-minute lecture in the field of interest to demonstrate his or her abilities.
If you are lucky and catch the eye of a top expert, you may have a greater opportunity.
Naturally, the participating mathematicians will not let go of this opportunity to intuitively understand the latest research trends in mathematics and supplement their knowledge in areas of interest.
Of course, due to the current development of mathematics, there are quite a lot of reports at each International Mathematical Congress.
There are hundreds of invitation-only presentations, not to mention those ten-tenth presentations that have been independently applied for, and the number is even higher.
In order to allow mathematicians to find lectures that interest them, the organizers of the International Mathematical Union have planned these applied reports by category.
This year's International Mathematics Congress has roughly divided into more than twenty categories.
Xu Chuan wasn't sure about the specific categories. He didn't look at the tables carefully.
In fact, when he has reached this point, most lectures have no value. Generally speaking, only lectures held by mathematicians of the same class have so much value.
After all, the report meeting is not a private communication, it is for mathematicians from all over the world. At this kind of meeting, many imperfect things cannot be presented. However, the quality of the lectures at the International Congress of Mathematicians is very high. Many times, some top mathematicians will also look for lectures by other experts that they are interested in to learn some mathematical knowledge in other fields.
In the venue, Xu Chuan came with four students in formal attire.
Due to the request of the International Mathematical Union, he had two lectures here. One was about the Xu-Hodge theorem, which was arranged in the afternoon of the third day.
The other session is about the expanded application of the Xu-Weyl-Berry theorem that has been fought over by the astronomy and astrophysics communities, and is scheduled for 9 a.m. on the first day.
This arrangement is, on the one hand, to attract astronomers and astrophysicists to attend the opening ceremony and expand the influence of mathematics.
On the other hand, it is convenient for the astronomers and astrophysicists who came to attend the meeting to leave early after listening to the report.
After all, the International Mathematical Congress lasts for nine full days.
At eight o'clock, the venue was already packed with people. The crowds were so crowded that there was almost no room left in the huge venue.
However, nearly half of the scholars participating in this lecture are not mathematicians.
At the International Congress of Mathematicians, more than half of the scholars who came to listen to a lecture by mathematicians were not mathematicians. This was also a rare thing. This was the first time in history.
"Professor, come on!"
As the report meeting was about to begin, Amelia, who was sitting next to Xu Chuan, cheered him up with a smile.
Xu Chuan smiled and nodded, stood up and walked onto the podium.
Although the Fields Medal medal was stolen at this International Mathematics Conference, the standards have never been lowered.
Taking the microphone from the host, Xu Chuan handed a USB flash drive to the staff and connected it to the virtual projection.
The contents of the USB flash drive are the contents of this lecture, and the International Mathematical Union also has a backup. However, considering that sometimes the presenter will make some minor changes to the content of the report, the copy provided by the presenter on site is generally used to facilitate the adaptation of the presenter's academic report.
Of course, such large-scale changes are definitely not allowed. For example, the report you submitted to the International Mathematical Union was the Hodge Hypothesis, but it was temporarily changed to the Riemann Hypothesis. This is not acceptable. If you do this, you are playing tricks on others and wasting everyone's time.
Xu Chuan has no intention of changing the submitted content. Today’s report meeting was requested by many top scholars in the astronomy and astrophysics circles to the Mathematics Alliance. What he submitted has been seen by most of the people in the audience. Changing it is quite troublesome.
As Xu Chuan came on stage, the originally noisy and noisy venue suddenly became quiet. More than 2,000 people in the venue all looked at him.
This year's International Mathematics Congress had less than 4,000 participants, including nearly a thousand non-mathematicians.
This report meeting gathered nearly half of the people at this International Mathematics Conference.
More than 20 other venues reported that the venue was divided into half. On average, there were only more than a hundred people in one venue. The disparity in the number of people was so huge that it was extremely rare.
Originally, many mathematicians were not very interested in the expanded application of the Xu-Weyl-Berry theorem, but a large number of people from the astronomy and astrophysics circles came together and actually aroused their interest.
In addition, there were no presentations by other top experts today, which resulted in Xu Chuan attracting nearly half of the people by himself.
Facing nearly 2,000 people in the audience, Xu Chuan smiled calmly, briefly introduced himself and the content of this lecture, and then began to explain the expanded application of the Xu-Weyl-Berry theorem.
".To truly understand and utilize the Xu-Weyl-Berry theorem, you need to fully understand the weak Weyl-Berry conjecture and the proof process of Weyl-Berry."
"This extension is not simply developed from the Xu-Weyl-Berry theorem. Some mathematical methods in the proof of the weak Weyl-Berry conjecture are also core."
". A fairly accurate upper and lower bound calculation was made for the counting function N (λ) associated with the fractal drum, and then a 'small opening' was opened between the non-connected branches of the area to connect the non-connected areas. Using this This method turns the example of non-connected regions discussed by previous people into the situation of regions. By this means, discontinuous eigenvalues can be continuously connected."
"And the parameters of boundary values"
In the venue, Nobel Prize winner Professor Sal Perlmutter sat in the front row, wearing glasses and looking at Xu Chuan on the stage. After listening attentively for a while, he poked his friend Brian Schmier next to him with his hand. special.
“Our last application was really the right choice.”
Brian Schmidt did not turn his head to reply, but just nodded in response.
He was reluctant to turn around and talk to Perlmutter beside him, fearing that he would be distracted and miss some details.
This time the report meeting, the young man on the stage, even if it had just begun, made him see something he had never seen before.
Very detailed, interesting and practical. At least, it is for the field of astrophysics to calculate parameter information of distant celestial bodies.
In the past, few people in the astronomy and astrophysics circles could use the Xu-Weyl-Berry theorem to expand its application to complete the calculation of parameters of distant celestial bodies.
But after this report meeting, there will definitely be more people. At least, there is a high probability that he can understand it, and Sal Perlmutter next to him can also understand it.
Astronomers and astrophysicists have gained a lot, and the mathematicians in the venue have also gained a lot.
Although the extended application of the Xu-Weyl-Berry theorem is a method for calculating distant celestial bodies and is not applicable to other mathematical calculations, in the final analysis, this is mathematics.
is mathematics, then its basis applies to mathematics.
Whether it is the precise calculation of the counting function N (λ) associated with the fractal drum in the proof of the weak Weyl-Berry conjecture; or the torsion method in the Xu-Weyl-Berry theorem
These are quite exquisite things. When separated, each one is wisdom. When combined together, it is knowledge created with wisdom.
As for knowledge, everyone can learn and absorb it, transform it into something of their own, and then apply it to other problems.
On the podium, Xu Chuan followed the PPT copy bit by bit to explain the expanded application of the Xu-Weyl-Berry theorem.
Different from the past, this time he spoke in great detail, breaking down almost all the key details of calculations.
The joint request from several Nobel Prize winners and dozens of top scholars still needs to be responded to seriously.
On the stage, Xu Chuan explained seriously.
Most of the scholars in the audience were listening attentively. Even the students who had gained knowledge with their tutors were immersed in it.
This is not so much a report meeting as a classroom.
On the podium, a teacher was giving a lecture, and below the stage, two thousand students were listening and studying seriously.
Preaching, receiving karma, and solving doubts are the way people go~
