I really just want to be a scholar

On November 11, Miami, as the southernmost city in the United States, has not yet ushered in the invasion of the super cold air mass of the "Little Ice Age". Although the temperature fell below 4 degrees Celsius, compared with the northern areas that are shrouded in super blizzards, Miami is The weather in the city can still be called "excellent".

This also makes journalists particularly active. At least more than 200 journalists from various countries gathered inside and outside the famous Miami Hotel because the International Mathematics Conference, the largest and most important conference held every four years in the international mathematics community, is organized by IMU. A conference of mathematicians is being held here.

The International Congress of Mathematicians is known as the "Olympic Games of Mathematics" and it is well-deserved. This year's conference was attended by more than 90 of the best well-known mathematicians from more than 4000 countries.

Each International Congress of Mathematicians invites a group of outstanding mathematicians to give one-hour academic reports at the conference, or 45-minute academic reports at group meetings of subject groups.

However, this year is a little special, because IMU specially reserved all the time on the second day of the conference, the morning of January 1, for two mathematicians, whether the two mathematicians are giving one-and-a-half-hour reports each, or more The two-hour long report will break the record of the longest report time in the history of the International Congress of Mathematicians.

——Of course, it is not ruled out that the two mathematicians only gave a half-hour report, and then used the remaining time to communicate with the mathematicians present.

The reason why it is "uncertain" is because the IMU meeting agenda only states "the morning's report exchange session, the content and form of which are determined by the speaker."

Such a special and overly loose arrangement should logically arouse great criticism, but the nearly 4100 mathematicians from various countries attending this meeting had no objections to it and were even full of expectations - just because of these two The mathematicians who gave the report were none other than the "Academician Qin Ke" and "Academician Ning Qingyun" who are now in the spotlight and known to everyone!

Putting aside their great halo and fame, the brilliant performance of the two of them in the public review meeting of Hodge's Conjecture yesterday was enough to make any envious or arrogant people shut up. I couldn't complain at all about such obvious "special treatment".

These two young academicians from Xia State have such super strength that people cannot help but admire!

Of course, for those Mesozoic mathematicians who had the opportunity to go on stage to give reports, their mood was more nervous and uneasy.

Now that IMU has given Qin Ke and Ning Qingyun such unprecedented lofty treatment, no one is sure whether IMU will make an exception and award them a second Fields Medal - the mathematics community and even the media have already been discussing this. .

If Qin Ke and his wife occupy two more Fields Medal spots this year, they will only be able to compete for the remaining two spots.

Who doesn’t want to win the highest award in the international mathematics community and aspire to the top of mathematics? Fighting for the possibility of only two places!

For this reason, they no longer paid attention to the reports of Qin Ke and Ning Qingyun, and had been carefully and meticulously preparing for the report on stage. Their performance on stage will largely determine whether they can win this Fields Medal.

In this way, with the attention and expectations of countless people, the International Congress of Mathematicians kicked off.

On the first day of the International Congress of Mathematicians, there was the usual opening ceremony in the morning, and then the formal first round of reporting sessions began.

However, many mathematicians had dark circles under their eyes and yawned constantly during this day, and some even fell asleep during the speech by Mr. Athol Gibson, Chairman of the Executive Committee of IMU. It is said that they stayed up all night and kept watching the live video recording of yesterday's guess, which led to their poor spirits today.

Qin Ke and Ning Qingyun also attended the report meeting on the first day. For them, listening to such a report was not only an opportunity to expand their network, meet more mathematicians, and understand the latest trends in the mathematics world, but also a rare opportunity to relax and relieve fatigue. Free time.

Moreover, in the afternoon of the first day, Academician Tian Jianlan, Ning Qingyun’s teacher, took the stage to give a report. It was the first one in the afternoon, so the two of them would not miss the opportunity to support their teacher.

I don’t know if it’s for the sake of Qin Ke and his wife, as many as 15 mathematicians from Xia State were invited to give reports at this International Congress of Mathematicians.

其中燕大4人，清木5人（含秦克和宁青筠），国内另有5家高校和科研机构的6名数学家作邀请报告。其中清木大学的田剑兰院士作的是1小时大会报告，其余燕大、清木有4位教授作45分钟邀请报告，剩下的夏国数学家在分组讨论会上作10分钟的学术报告。

As we all know, it is a high honor to be invited by the International Congress of Mathematicians to give a one-hour and 1-minute report, which shows that his work has a great impact internationally.

Academician Tian Jianlan was invited to give a one-hour conference report. This not only reflects the factors of Qin Kening Qingjun, but also is an affirmation of her own strength by IMU.

In fact, after the old academician Wang Heng officially retired, when it comes to number theory masters in Xia Guo who were between 40 and 80 years old, no one can beat academician Tian Jianlan.

She has a solid foundation in knowledge and quick thinking. Her strength in number theory is no less than that of her mentor, Mr. Chen Jingrun. She publishes more than five papers in international first-tier academic journals every year, including "Annals of Mathematics" and "New Advances in Mathematics". Journal.

Before Qin Ke and Ning Qingyun entered Qingmu University, she was the one who single-handedly supported the international reputation of the Department of Mathematics at Qingmu University. Unfortunately, because of her arrogant and stubborn personality, she could not tolerate things in her eyes, and she was not used to things that she did not like. She then criticized and resisted, which made her offend too many people, and she was never able to be promoted to an academician. Until she accepted Ning Qingyun as a disciple, with the rise of Qin Ken and Ning Qingyun, no one in the country finally dared to stumbling her again. Only then was he successfully elected as a mathematician...

Tian Jianlan stood on the podium, looking at the dark crowd under the stage, with mixed feelings in her heart. She knew that she had such an opportunity to receive the honor of a short report because of her student Ning Qingyun. But no matter what, if she can stand on such an international stage, she will show the best side of Xia Mathematicians to the Xia Mathematics community and Qingmu University.

The report she gave was "Some Thoughts on the Integration of Number Theory Issues and Geometric Dimension Issues". Participating in part of the creation process of "New Geometry" made her thinking suddenly broaden. At the level of a grand master like her, once her thinking changes, she can integrate many theoretical things. For example, she has extremely unique and profound insights into the dimensionality of number theory and geometry.

When her report was over, the audience burst into warm applause that was anything but polite. Many famous mathematics masters commented on her report in the same way - "No wonder she can teach such an outstanding academician as Ning Qingjun." student, Academician Tian’s level in number theory is really impressive.”

Qin Ke and Ning Qingyun clapped equally vigorously. Qin Ke smiled softly at his little cabbage: "I didn't expect Teacher Tian to make further progress. It's amazing."

"Yeah...I found that I still have a lot of number theory processing skills that are not as good as Teacher Tian's. I have to work harder and harder in the future!" Ning Qingyun's face was flushed with excitement, and she was happy for her teacher at the same time. , also clenched his white little fists and ignited full of fighting spirit.

Academician Tian Jianlan's first report in the afternoon of the first day was a head start, which cheered up many drowsy mathematicians. The next two reports were also quite good, showing that the international mathematics community is flourishing.

Professors Huffman and Lepe, who had won the Fields Medal with Qin Ke and his wife four years ago, sat at their table during the dinner and commented: “The mathematics community has indeed become more and more prosperous in recent years. It should be the credit of both of you, you two shine so brightly, if you don’t want to be completely overshadowed by your shine, you have no choice but to catch up.”

What they didn't say was that they themselves didn't dare to relax even a little bit, and they had no intention of enjoying the admiration from all parties after winning the Fields Medal. Every time Qin Ke and Ning Qingyun came up with new dazzling results, it stimulated them to make continuous progress. , just so as not to be left far behind by these two winners of the same session... This is also a microcosm of the obvious acceleration of the development of the international mathematics community in recent years.

In the blink of an eye, it came to 8:30 in the morning of the next day. Apart from the award ceremony to announce the grand prize, the most attention-grabbing moment of this International Congress of Mathematicians arrived.

The number of viewers of IMU's live broadcast rooms on video platforms in various countries has increased sharply, especially in Xia Kingdom, where the number of viewers has exceeded 3 million, which means that on average one in every five Xia Kingdom people is watching this live broadcast. Even though it happens to be a weekend, this is still a very exaggerated and terrifying number.

Qin Ke and Ning Qingyun stepped onto the podium hand in hand amid the attention of hundreds of millions of people.

The applause rang out like a tide and gradually stopped until the two stood still on the stage.

Qin Ke waved his hand coolly: "Hello everyone, I am Qin Ke from Xia Kingdom."

Ning Qingyun also waved her little hand and said with a smile: "Hello everyone, I am Ning Qingyun from Xia Kingdom."

Introduce yourself simply, without any unnecessary titles or titles, because they are not needed at all. Their resumes are probably recited by every mathematician present.

Qin Ke smiled and said: "I believe everyone is very concerned about the format and theme of our report today. After discussing it with my wife, I decided to give a one-hour report each..."

Everyone was surprised. It only took an hour to give a report? Didn’t break the IMU’s highest duration record?

Someone soon speculated that this might be because they did not want to exceed the length of yesterday’s teacher, Academician Tian Jianlan’s report, right?

Just listen to Qin Ke continue: "Then there will be an hour and a half of free communication. We will discuss any mathematical problem in any sub-discipline with all the audience here."

Mathematics problems in any sub-discipline!

The whole place was shocked!

There are more and more specialization subdivisions in modern mathematics, and there are so many sub-disciplines. Even the resurrection of Gauss and the reincarnation of Euler will no longer be as proficient in dozens of mathematical sub-disciplines in different fields as before. Now Qin Ke actually says that he must Feel free to discuss any mathematical problem in any sub-discipline?

Even though Academician Qin Ke has always been known for being knowledgeable and good at many mathematics sub-subjects, this... is too exaggerated and unbelievable?

Qin Ke ignored the surprise and whispers in the audience. He gestured to the staff, who immediately projected his PPT.

"Let's start our reports first. The topic of my report is "Thirteen Advanced Algorithms for Efficiently Modeling Massive Big Data", and the topic of my wife's report is "Experience in the Application of General Analysis in Big Data Modeling" share"."

The atmosphere in the whole place was boiling again, and countless people stood up.

In the past year, Qin Ke and Ning Qingyun, in addition to "new geometry" in mathematics, the most popular, most eye-catching and amazing thing is their big data analysis and modeling capabilities, which completely surpasses the meteorology of various countries. On top of the central scientific research team.

No one expected that Qin Ke and Ning Qingyun would share their unique secrets at the conference!

This is simply...simply...no one knows how to express their feelings at this moment. They can only sit down quickly and find paper and pen, for fear of missing any precious second of time.

The staff in charge of the camera also hurriedly checked the machinery and equipment repeatedly to avoid missing such an extremely important scene.

Qin Ke had already anticipated the scene before him. He smiled softly and began his one-hour report:

"When it comes to big data analysis algorithms, I believe many people will immediately think of hash mapping, bitmap, Trie tree, simhash algorithm and the like. In fact, these algorithms have great limitations. Among the current mainstream related algorithms in the world, they can barely The only ones that can be called qualified are supervised learning algorithms based on nonlinear function fitting of multi-layer connection weights - neural network algorithms. But the algorithm I am talking about today is different from these algorithms..."

As Qin Ke's report began, the whole place fell silent, except for the "swishing" sound of the pen tip desperately scratching the paper.

When Ning Qingyun gave her one-hour report, the reaction of the audience was similar. No words were spoken, no one was distracted, and everyone took notes as if they had found a treasure, trying to digest and absorb the essence of knowledge.

In fact, many of the reports made by Qin Ke and Ning Qingjun were publicly lectured within the Fluid Mechanics Laboratory and shared with the scientific research team of the European Meteorological Center, but they were not formally explained in detail in public.

Qin Ke selected some of his original main algorithms to explain. The purpose is naturally to improve the mathematical community's ability to analyze and model big data. Especially since many mathematicians present have cooperative relations with meteorological centers of various countries. If they can Mastering these algorithms will greatly enhance the data processing and modeling capabilities of national meteorological centers and reduce his guidance workload.

As for whether some people with ulterior motives will thoroughly study his report and establish a new mathematical model that is not inferior to his extreme climate disaster analysis and prediction model, the fluid mechanics laboratory will lack the core competition. force?

That's simply impossible. It's impossible to go into too much depth in just one hour. Especially the algorithms of big data analysis are dynamically changing. Qin Ke's algorithms must constantly be optimized with the times. These mathematicians can Mastering one-third of the mathematical modeling thinking is quite remarkable.

And without the help of LV4's low light, it would be impossible to build such a huge computer analysis program.

Qin Ke and Ning Qingyun's one-hour reports each ended quickly in this tense atmosphere. When Ning Qingyun put down his pen and bowed slightly to the audience at the same time as Qin Ke, the audience Most of them are still writing and writing hard and forget to applaud.

It wasn't until more than half a minute later that the audience who came back to their senses clapped their hands one after another. Then the applause became louder and louder, and finally turned into a deafening frenzy!
