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, 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."
"The previous ideas should be changed. 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."
"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." Lan.
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 over each person, it falls directly out of fifty places.
The scale is too big, and any change will be a big shock.
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 much about it. He actually didn't care much about the domestic academic environment now, or he didn't think much about it.
What he wants now is just a cleaner academic environment in China.
This is difficult for other people 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 could 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, his superiors will arrange for someone to dissuade him.
But if it's difficult to go abroad, there might be a chance to organize the International Mathematical Congress 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 bit late to take action now, it must still be done. As a country with the second largest economy in the world, it has only held an International Mathematical Congress, which is too shabby.
However, it is also a troublesome thing to do. You have to contact some mathematicians at home and abroad to jointly promote it.
It would be difficult for him alone, even as a Philippine Prize winner, to promote this matter.
"Forget it, let's communicate first. It's not urgent anyway. The meeting and voting won't be held 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 in China, if you are able 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.
Lan
Of course, at the International Congress of Mathematicians, in addition to the one-hour and forty-five-minute reports 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 the mathematics community 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 were hundreds of invitation-only presentations, not to mention the number of 10-tenth presentations that were independently applied for.
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 how many specific categories there were. He didn't look at those tables carefully.
This chapter is not over yet, please click on the next page to continue reading! In fact, at his point, most lectures are of little value. Under normal circumstances, only lectures held by mathematicians of the same class are valuable.
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 in formal attire with four students.
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 the astronomy and astrophysics communities have fought for, 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 will be held 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, when a mathematician gave a lecture, more than half of the scholars who attended the meeting were not mathematicians. This is also a rare thing. This is 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 disk to the staff and connected it to the virtual projection.
The USB flash drive contains the content of this report meeting, and the International Mathematical Union also has a backup. However, considering that sometimes the presenter will make some minor changes to the report content, the copy provided by the presenter on site is generally used.
, convenient for adapting speakers to make academic reports.
Of course, that kind of large-scale changes are definitely not allowed. For example, the report you submitted to the International Mathematical Union was Hodge's conjecture, but it was temporarily changed to the Riemann conjecture. This is not acceptable. You are doing this.
Toying with others and wasting everyone's time.
Xu Chuan has no intention of changing the content he submitted. 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 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 Congress.
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 Xu-Weyl-Berry's 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, so Xu Chuan attracted 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 expansion 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, and the non-connected area was calculated
Connectivity...In this way, the examples of non-connected areas discussed before are turned into regional situations. Through this method, discontinuous eigenvalues can be continuously connected..."
"And the parameters for the 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 carefully for a while, he poked his friend Brian Shi next to him.
Mit.lan
“Our last application was really the right choice.”
Brian Schmidt did not turn around 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.
It is very detailed, very interesting, and very practical. At least, it is suitable for calculating parameter information of distant celestial bodies in the field of astrophysics.
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 around him can also understand it.
Astronomers and astrophysicists have gained a lot, and the mathematicians at the conference 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 foundation 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.
......lan
On the podium, Xu Chuan followed the ppt text to explain the extended application of the xu-weyl-berry theorem bit by bit.
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, and even those 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 is giving a lecture, and below the stage, two thousand students are listening and studying seriously.
Preaching, receiving karma, and solving doubts are the way people go~
