I really just want to be a scholar

Chapter 995 The most perfect mathematics! Upgraded earthquake prediction model!

This was the first time that Tao Zhexuan saw Qin Ke enter the "inspiration amplification" state with his own eyes, and he had an unknown feeling.

He didn't dare to disturb Qin Ke, so he asked Ning Qingyun in a low voice: "Xiao Ning, do you mean that Qin Ke has probably found ideas and inspiration?"

He subconsciously looked at the time. Less than four hours had passed since the three of them saw this information. He had just roughly understood this mathematical model. Some of the in-depth applications of NS equations and regression algorithms needed more time. It takes time to think about it, let alone judge where and whether this mathematical model has flaws.

Ning Qingyun's progress over there should be slower than him.

But then Ning Qingyun said that Qin Ke had found the problem and even had a solution?

Lao Tao: "..."

Although I know that Qin Ke is recognized as the God of Mathematics, and I have seen his "super performance" after getting along with him in the past two years, the huge gap in handling the same problem at the same starting point this time still makes Lao Tao a little bit disappointed. blow.

Lao Tao looked at Qin Ke who was writing rapidly and asked in a low voice: "How long will he be like this?"

Ning Qingyun shook her head, but her eyes were still looking at Qin Ke, with unconcealed admiration and love: "Not sure, the longest one was almost ten days, and the shortest one was about twenty or thirty minutes."

Lao Tao put down the materials and sighed: "How about we drink tea and wait for his answer? Being in the same era as such a god of mathematics is really stressful..." But after that, he picked up the materials again: "Calculate Even if I can’t compare with God, I still want to shorten the gap with God, even if it’s just a little bit.”

"It's done... this way it's perfect, this way it looks good!"

Qin Ke focused on thinking throughout the day, forgetting whether he had eaten or drank water - maybe Ning Qingyun fed him but he had no memory - finally, when the last ray of sunset on the horizon disappeared, Qin Ke With powerful strokes, he wrote a series of extremely complex nonlinear partial differential equations.

As Lao Tao said, no matter how powerful Qin Ke is, if you want to be his second best and stay by his side, you can't give up your efforts and blindly rely on Qin Ke like an ordinary person.

Now, he was writing down his bursts of inspiration on these blank sheets of paper.

No matter how far away you are from him, as long as you persist in your efforts, you will always get closer to him. In this way, you may be able to help him more and share some of his pressure.

Qin Ke has a thick piece of blank paper on his desk so that he can jot down notes whenever he has inspiration.

Qin Ke grinned and pointed at the complex calculations written on the white paper that filled the whole page: "This is the core equation set for optimizing the earthquake prediction mathematical model of the European Meteorological Center... Jun'er, next, I leave it to you and Lao Tao, I’m going to take a nap first.”

……

Therefore, after repeated thinking, he successfully found the deeper source factors of energy changes based on the "appearances" studied by the European Meteorological Center's earthquake research team.

If the European Meteorological Center's earthquake research team has used the NS equation to some extent before, slightly improving the accuracy of predictions, now Qin Ke's variants of the NS equation are truly suitable for accurately describing earthquake energy fluctuations. algorithm core.

Qin Ke looked at the dozens of lines of complex calculations he had written, and his heart was filled with joy. This was the heartfelt joy of opening the door to the truth and seeing the truth!

“E+▽(uu)=CvρT－p＋ρF＋μΔv+1/2ρ（μ^2+ν^2+ω^2）+▽·[（veff）（▽u+▽u^T）]……”

Based on the collective wisdom of the European Meteorological Center's earthquake research team for several months, Qin Ke finally cleared away the fog and completed the last piece of the puzzle!

Qin Ke breathed a long sigh of relief, raised his head, and saw Ning Qingyun's gentle and caring eyes.

In the system's "Inspiration Amplification" state, all of Qin Ke's brain cells were happily active, and the sparks of thinking burst out, emitting a bright light of wisdom... He wrote nearly two hundred pages of manuscript paper, During this period, with the assistance of LV5's Shimmer, the historical data was checked and verified multiple times.

The mathematical model of the European Meteorological Center's earthquake research team is overall correct, and has taken into account almost all the influencing factors involved in current theories, and assigned different weights based on historical data. Unfortunately, this mathematical model only describes The appearance fails to see the more substantial origin.

These nonlinear partial differential equations comprehensively consider the Hamiltonian operator, Laplace operator, mass kinetic energy flux, and also integrate various situations of shear stress, normal stress, and non-Newtonian fluid. A series of expansions and completions to the NS equation, making it more suitable for describing energy fluids under the earth's surface.

Qin Ke is different. He is both a mathematician and a physicist, and both are at a god-level level.

Ning Qingyun pursed her lips and smiled, stared at Qin Ke deeply for a while, then lowered her head and read the information seriously again.

But we can’t blame them. This data model was established by European mathematicians based on the research results of seismologists and physicists. Mathematicians don’t know much about physics, and physicists and seismologists are not very good at mathematical modeling. , which makes it difficult for them to truly find the hidden truth in the huge and complex data.

After being in the "Inspiration Amplification" state for six hours, even Qin Ke, who had reached LV7 in sports and was extremely energetic, felt exhausted and exhausted as if his brain cells had been drained.

“E=▽·μ((▽u)+(▽μ)^T)+▽·(μ▽u)+ρdt/dv(∮Vσ+∮Vx)+Ψ*S(4δ,nδ)∪tSδ… …”

Fortunately, it was different from before. Although his face was pale and sweat broke out on his forehead, it was not to the point where his whole body collapsed and he suddenly lost consciousness.

He took the towel handed by Ning Qingyun to wipe off the sweat, took another sip of warm water, and then, with the help of Lao Tao, he managed to lie down on the lunch break bed in the office. The next second, he fell into a deep sleep. .

Lao Tao looked at Qin Ke who was breathing evenly, and turned to Ning Qingyun in disbelief: "He fell asleep now?"

This was the first time he had ever seen someone fall asleep for a second.

"Well, it's okay, he's just too tired." Ning Qingyun said this not only to Lao Tao, but also to Wei Feng and Wei Jing, who were standing a few steps away and looked nervously and worriedly.

Wei Feng had seen Qin Ke in this state several times, but he still couldn't worry and said to Wei Jing: "Just in case, let the doctor come."

In this "Chief Scientist Building" there are not only more than 24 mathematicians from all over the world in the field of mathematical analysis, but also a "decision-making team" with a group of veteran scientists representing the scientific research circles from various countries. I didn't dare to neglect, so I set up a special medical room and arranged for a senior medical team to stay on duty hours a day.

This medical team includes both traditional Chinese medicine and Western medicine. They are all experienced doctors who have been practicing for more than 20 years. The lowest level is also a chief physician. There are also five expert professors. In addition, they are also equipped with various emergency-related equipment and common drugs. Even surgeries such as acute appendicitis can be performed immediately. It can be said to be a small hospital.

Wei Jing quickly called the doctors. The doctors were extremely nervous. After a lot of confusion, the examination results were just as Ning Qingyun said. Qin Ke just fell asleep due to excessive fatigue.

After all the fuss, Qin Ke still slept on the lunch bed in the office, and Wei Feng carefully arranged for security personnel and medical staff to stay by his side 24 hours a day.

On the other side, Lao Tao and Ning Qingyun were also looking carefully at Qin Ke's hundreds of pages of drafts. The more they read, the more fascinated they became. After nearly an hour, Lao Tao first put down the manuscript and sighed: "Perfect. You can't find any problems at all, this is perfect mathematics!" Wei Jing, who had been standing nearby, couldn't help but crane her neck and take a few glances. She saw that Academician Qin's handwriting was quite straight, but what he wrote was all difficult and difficult. Although she didn't understand any mathematical formulas, she didn't see any beauty such as symmetry. Anyway, after looking at it for a while, she felt that "looking at it was in vain." She didn't know where the word "perfect" that Professor Tao said came from.

"Xiao Ning, have you seen it? Especially the derivative changes and expansions of the NS equation, so that it can be used in the flow of energy under the earth's surface. This is probably the first time in the history of mathematics that someone has described it with such a clear set of expressions. The energy in the underground flows! It’s amazing, it’s amazing! I couldn’t figure it out for a lifetime of research! But Qin Ke only spent most of the day!”

The more Lao Tao talked, the more excited he became. He couldn't help but slap the table and shout: "Qin Ke is so amazing!"

Ning Qingyun was embarrassed to answer. After all, she was praising her husband, but she was also full of pride.

Gently stroking the handwriting on it, Ning Qingyun seemed to be having a mathematical conversation with Qin Ke.

She said softly: "Now that the earthquake prediction mathematical model provided by the European Meteorological Center has a new 'soul', it is time for us to upgrade it."

"Yes, the most critical and difficult part has been conquered by Qin Ke. We will take care of all the remaining work!"

Neither Ning Qingyun nor Lao Tao are familiar with how to convert mathematical models into computer programs that can run efficiently on Weiguang, but it doesn't matter, they can just leave this part of the work to Weiguang himself.

……

Europe, London.

Like the Xia Kingdom, Europe at this time was also in the hot summer of high temperature and drought. Under the heat island effect, the city was as unbearably hot as an oven.

In the headquarters building of the European Meteorological Center, Director Mr. Figueiredo and Chief Scientist Professor Goldberg were also like ants in a hot nest, pacing back and forth in the office.

But it's not because the weather outside is too hot, but because I feel too anxious inside.

As long as they think about the possibility of three major earthquakes with magnitudes above 6.0 in three or four days, they have not yet determined whether this prediction is correct or whether an emergency evacuation notice should be issued.

Although the epicenters of these three earthquakes were not within the main urban areas of the city, the aftershocks were enough to seriously damage three large cities with a population of one million.

That’s millions of lives! There are also countless property and economic losses, which makes people’s scalp numb just thinking about it.

Faced with this huge pressure, it is not difficult to understand that the two of them could not eat well and sleep well.

"Sometimes I feel that Academician Qin from the Xia Kingdom... really gives people hope and despair." Director Figueiredo finally sat down, took a sip of the cold and bitter black tea, and said in a half-joking, half-exclamation tone. :

"If big data analysis, mathematical modeling and natural disaster prediction models were not as widely and deeply applied as they are now, we would have accepted our fate and would not be as worried about gains and losses as we are now."

Professor Goldberg said helplessly: "This is because we are not good at it. We have established a half-baked earthquake prediction model. Even we are not fully sure about it. Who can we blame?"

He was mocking himself, but Professor Goldberg also knew that due to the inability to accurately measure underground conditions and the imperfection of the earthquake theory system, earthquake prediction has always been difficult, even more difficult than weather forecasting.

A year ago, it was only possible to predict a few similar earthquakes that had occurred. Unknown earthquakes could only be predicted ten seconds in advance at most. Like now, a 6.0-magnitude earthquake can be predicted five days in advance. An earthquake is almost unimaginable.

This also encourages Academician Qin Ke to vigorously promote mathematical analysis and modeling, and use the combination of big data and mathematics to open a new chapter in human prediction technology for natural disasters.

However, there are too many gaps in this new chapter. The number of professional talents, especially compound talents, is far from keeping up with demand. Except for the team of Academician Qin from Xia Guo who can achieve more accurate predictions, teams from other countries are still in the unfamiliar field. The stage of groping forward in the world - this is still under the guidance of Academician Qin Ke, which makes this step much faster.

Without the guidance of Academician Qin Ke, according to the normal process, it would have taken at least twenty years for the European Meteorological Center to establish the current half-baked earthquake prediction model, instead of less than a year like now. time.

Therefore, Professor Goldberg is full of gratitude and admiration for Qin Ke, and he is willing to follow his lead.

The same is true this time. Faced with such a major disaster, Professor Goldberg was unable to make a judgment and could only pin all his hopes on Academician Qin Ke in that distant country.

Seeing that Director Figueiredo still looked depressed, Professor Goldberg comforted him and said, "Mr. Figueiredo, don't worry. Academician Qin replied to the email and said that our request for help will be given the highest priority."

Director Figueiredo shook his head and sighed: "If Academician Qin had followed up on this earthquake prediction project from the beginning, I believe he would have given us an accurate answer within two days, but now..."

Professor Goldberg also knew that this was indeed difficult, the time was too short, and Academician Qin didn’t know much about the project.

But he still consoled him: "Academician Qin has always been able to create miracles, and maybe this time there will be a miracle record as well."

Director Figueiredo said dullly: "There are only ten hours left..."

Professor Goldberg looked at his watch. It was indeed past two o'clock in the afternoon, and there was only half a day left before the two-day time limit.

In fact, he had also prepared for the worst. If Academician Qin still didn't reply to the email by 12 o'clock tonight, he would have no choice but to issue an earthquake warning. In the face of such a major disaster, he would rather make a false alarm and be criticized. It is better to be bloody than to have a disaster actually happen and cause huge irreparable losses.

Just when the atmosphere was dull and almost solid, the secretary hurriedly pushed out of the room, excitedly waved the printed document in his hand and shouted: "Reply, Academician Ning from Xia State has replied to the email! He said that the earthquake prediction model has been optimized. , and re-deduced the results, and said that if possible, it would be best to immediately send them today’s latest data for a second deduction to verify the results!”

Professor Goldberg and Director Figueiredo were surprised, happy and confused, and couldn't help but look at each other.

How could it be an email from Academician Ning? Where is Academician Qin?

It's not that I don't believe Academician Ning. After all, Academician Ning is also very high-level and works on the same team as Academician Qin. He is Academician Qin's right-hand man. However, this email was not answered by Academician Qin, which makes people a little uneasy.

Anyway, let’s go and have a look.

Professor Goldberg hurried over and took the printed email content from the secretary's hand, and read it at a glance.
