Chapter 216 People's Journey

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. There will be too many surprises if we stay there."

"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 focused on 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 be happy, 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, actually improving the treatment of scientific researchers, especially graduate students, is the real feasible way."

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 that 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 a cleaner academic environment in the country.

This is difficult for others to do, but it is not so difficult for him. When the country invites him, he makes a request and it is enough to say something from above.

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 Prize winner, to promote this matter.

"Forget it, let's communicate first. It's not urgent anyway. There won't be a meeting to vote 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 take the 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 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 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 Mathematics Congress.

There are hundreds of invited reports, not to mention the 10th report conference that is applied for on its own, which is even more.

In order to allow mathematicians to find the reports they are interested in, the organizers of the International Mathematical Union have classified and planned these reports.

This year's International Mathematical Congress has more than 20 categories.

Xu Chuan is not sure how many categories there are, and he did not look at the tables carefully.

In fact, at his level, most reports are no longer valuable. Generally speaking, only reports held by mathematicians of the same class have some value.

After all, reports are not private exchanges, but for mathematicians all over the world. At such meetings, many imperfect things cannot be brought out.

However, the quality of the reports at the International Congress of Mathematicians is very high. Many times, some top mathematicians will also look for reports from other big names that they are interested in to learn about some mathematical knowledge in other fields.

In the venue, Xu Chuan came with four students in formal attire.

At the request of the International Mathematical Union, he had two reports, one on the Xu-Hodge theorem, which was scheduled for the afternoon of the third day.

The other one was about the extended application of Xu-Weyl-Berry theorem, which was won by the astronomy and astrophysics community. It was scheduled for 9 am on the first day.

This arrangement, on the one hand, attracted those astronomers and astrophysicists to attend the opening ceremony and expand the influence of mathematics.

On the other hand, it was convenient for those astronomers and astrophysicists who came to attend the conference to leave early after listening to the report.

After all, the International Mathematical Congress will last for a full nine days.

At 8 o'clock, the venue was already crowded with people, and the huge venue was almost full.

However, nearly half of the scholars who attended this report were not mathematicians.

At the International Congress of Mathematicians, more than half of the scholars who came to listen to a mathematician's report were not mathematicians. This is also a rare thing. This is the first time in history.

"Professor, come on!"

As the report was about to start, Amelia, who was sitting next to Xu Chuan, smiled and cheered him up.

Xu Chuan smiled and nodded, got up and walked to the podium.

Although the Fields Medal was stolen at this International Mathematical Congress, the specifications 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 USB flash drive contains the content of this report, and the International Mathematical Union also has a backup. However, considering that sometimes the reporter will make some minor changes to the report content, all the copies used are generally the ones provided by the reporter on the spot, which is convenient for the reporter to make academic reports.

Of course, such large-scale changes are definitely not allowed. For example, you submitted a report on the Hodge conjecture to the International Mathematical Union before, but changed it to the Riemann conjecture when you came on stage temporarily. This is not okay. You are playing with others and wasting everyone's time by doing this.

Xu Chuan had no idea of ​​changing the submitted content. Today's report was requested by many top scholars in the astronomy and astrophysics circles to the Mathematical Union. What he submitted has been seen by most of the people in the audience. It is quite troublesome to make changes.

As Xu Chuan came on stage, the originally noisy and noisy venue suddenly became quiet, and more than 2,000 people in the venue cast their eyes in unison.

This International Mathematical Congress had less than 4,000 participants, including nearly 1,000 non-mathematicians.

This conference brought together nearly half of the participants.

The other 20 or so conference venues were divided into half, with an average of more than 100 people per venue. Such a huge difference in the number of people is extremely rare.

Many mathematicians were not very interested in the extended application of the Xu-Weyl-Berry theorem, but a large number of people from the astronomy and astrophysics circles came together to arouse their interest.

In addition, no other top-level lectures were arranged today, which led to Xu Chuan attracting nearly half of the people alone.

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 extended application of the Xu-Weyl-Berry theorem.

".To truly understand and use 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 process of the weak Weyl-Berry conjecture are also the core."

".The counting function N(λ) associated with the fractal drum is calculated with quite accurate upper and lower bounds, and then a "small opening" is opened between the non-connected branches of the region to connect the non-connected region. In this way, the example of non-connected regions discussed by predecessors is turned into the case of regions. Through this method, the discontinuous eigenvalues ​​can be continuously connected."

"And the parameters of the boundary value"

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 Schmidt with his hand.

"Our last application was really a correct choice."

Brian Schmidt did not turn around to reply, but just nodded to show his response.

He was reluctant to turn around and talk to Perlmutter beside him, fearing that he would be distracted and miss some details.

At this report meeting, the young man on the stage, even at the beginning, showed him something he had never seen before.

Very detailed, interesting, and practical. At least, it is for calculating the 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 extended application of the Xu-Weyl-Berry theorem to complete the calculation of the parameters of distant celestial bodies.

But after this report meeting, there will definitely be more people. At least, he will most likely understand it, and Sal Perlmutter beside him can also understand it.

Astronomers and astrophysicists have gained a lot, and 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, it is mathematics in the final analysis.

If it is mathematics, then its foundation is applicable 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 twisting method in the Xu-Weyl-Berry theorem

These are all very subtle things. When separated, each one is wisdom, and when combined together, it is knowledge created with wisdom.

And knowledge, everyone can learn and absorb, transform it into their own things, and then apply it to other problems.

On the podium, Xu Chuan explained the extended application of the Xu-Weyl-Berry theorem bit by bit according to the PPT copy.

Unlike in the past, this time he explained it in great detail, and he broke down almost all the key details related to calculation.

The joint request of several Nobel Prize winners and dozens of top scholars still needs to be responded to seriously.

On the stage, Xu Chuan explained seriously.

Under the stage, most of the scholars were listening carefully, even those students who came with their mentors to gain knowledge were immersed in it.

It is better to say that this is a class than a report meeting.

On the podium, a teacher is giving a lecture, and below the stage, two thousand students are listening and studying attentively.

Teaching, learning, and solving problems are what people do~
