Xueba's doctor's wife

Chapter 246 My Husband is Coming! (13, please subscribe)

Professor Wu Tao from the Department of Mathematics of Peking University is a top expert in PDE in China, especially in thermodynamic systems. do.

As everyone knows,

The Boltzmann equation describes the law of motion of a rarefied gas, and is the basic equation in statistical mechanics. The collision kinetic equation with it has important applications in nuclear energy technology, semiconductors, and plasmas. However, the Boltzmann equation The adult comfort problem of solution is the core problem in PDE.

And that's the problem he wants to solve.

of course,

For such an important content, a super expert in the field of mathematics must be invited to witness this great moment, and Fang Hao is among them.

In fact, Professor Wu Tao didn't want to call Fang Hao over. There was no way that something like that happened in Tsinghua University next door. Academician Chu was brutally slapped in the face by Fang Hao in full view. He didn't want to be the second Academician Chu.

But then again, if you don't invite this new mathematician over here, you'll always feel something is missing. After all, Fang Hao's reputation in the circle of young people exceeds that of any domestic scientist.

finally,
Still under the lure of fame and fortune, Professor Wu Tao took the risk of inviting this dangerous man to his press conference. The greater the danger, the greater the reward.

at the same time,

Fang Hao is chatting with two big cows in the field of mathematics, namely Academician Kong from the Chinese Academy of Sciences and Professor He from the University of Science and Technology. Academician Kong is mainly engaged in the field of differential geometry, while Professor He specializes in topology. The two are in their respective fields He has made great contributions, among which Academician Kong also served as the editor-in-chief of a certain mathematics journal.

The most important thing is that the two are not from the Qing dynasty.

"Professor Fang?"

"Do you have any expectations for the upcoming latest research on the Boltzmann equation?" Professor He asked Fang Hao, who was sitting beside him, with a smile.

"Uh"

"Actually, it's a bit." Fang Hao nodded, and said solemnly: "The general initial value of the Boltzmann equation, from the overall existence of the large initial value renormalization solution of the Boltzmann equation obtained for the first time through the weak compactness method After the uniqueness and regularity of the integrated solution have not been resolved, I think Professor Wu Tao should solve this problem."

"It's about the same as I guessed."

"I actually know Wu Tao very well." Professor He smiled and said, "He is usually quite arrogant, but he has strong academic ability."

As soon as the voice fell,
Professor He added to Fang Hao: "The key point is that he is not from the Tsinghua University."

"."

"Professor He, I am not the heinous person in your eyes." Fang Hao said awkwardly: "Academician Chu's question is not my original intention, but it is a bit ridiculous. As an expert in topology, you will tolerate it." An obvious mistake before my own eyes?"

"Professor Fang, don't get me wrong."

"I just want to remind you. Professor Wu is a good person." Professor He said with a smile on his face: "I don't have a good impression of Academician Chu, and his academic ability is a little bit."

at this time,

Academician Kong said: "Old He, you just need to be straightforward. That Chu guy doesn't have much academic ability, but his ability to make connections with the whole circle is outstanding. He likes to form cliques and disgust people."

Professor He nodded, looked at Fang Hao next to him, and said earnestly: "Professor Fang's Department of Tsinghua University occupies half of the country in the field of scientific research, and at the same time there are many of them in the field of ZZ, you"

"The position of academician will probably be suspended in the future." Professor He said.

"actually."

"You can take the route of a mathematician." Academician Kong said seriously: "Professor Fang's two mathematical papers created a new research direction, and at the same time provided the world with mathematical tools and the most basic framework theorems. The rules of the Ertz Award. You must win this award next year."

"Fields Medal"

"The position of academician of mathematics is definitely yours, but... if you want to enter as an academician of physics, I am afraid that it is the same as what Lao He said, and it is probably about to be suspended." Academician Kong couldn't help pausing for a while when he said this, and then continued Said: "Professor Fang, what do you think?"

"let it go."

Fang Hao shrugged, and said casually: "If possible... I still hope to enter as a physics academician."

Facing Fang Hao's choice,

The two didn't have too many thoughts, after all, the right to choose is in the hands of others.

In the Mathematics Lecture Hall of Peking University,

The audience is already packed to the extent that there are not only graduate students from the school, but also some famous mathematicians who come here. At this time, everyone is whispering about something.

Professor Wu Tao stood in the background, looking at so many people present, feeling a little excited in his heart, as he announced the latest research results, he would soon become one of the most powerful mathematicians in the country, this temptation It's kind of huge.

Of course,
With the rise of fame, various benefits also follow, and the position of deputy director should not be a problem.

There are still 3 minutes until the start,

Professor Wu Tao began to tidy up his clothes, and as the minute hand reached the designated place, Professor Wu Tao stepped onto the stage, and the originally noisy lecture hall became silent for a while, and everyone turned their eyes away To this middle-aged man.

"Thank you all for coming."

"I will publish the latest research on the Boltzmann equation later. I dare to say that this will be the most shocking moment in the mathematics world this year." Professor Wu Tao said confidently, "I would like to invite three guests, and All three are well-known figures in mathematics."

As soon as the voice fell,
Academician Kong and Professor He came to the stage one after another, followed by Fang Hao, who was the last one to come on stage.

The moment Fang Hao walked onto the stage, in a certain corner, Xiao Mili, who was hugged by Yu Qianqian, was a little excited when he saw his handsome uncle. He waved at Fang Hao excitedly, and Fang Hao also noticed his little niece and smiled slightly at her.

"Uncle smiled at the rice grains."

Xiao Mi Li hugged Yu Qianqian's neck, and said in her ear.

Yu Qianqian curled her lips, and immediately thought of the picture of her having a daughter in the future, and guessed that her daughter would also be pestering her father every day. If this is the case, wouldn't it be that there will be no time for married life in the future?

After introducing the three invited guests,
Fang Hao, Academician Kong and Professor He sat on the side, ready to witness Professor Wu Tao change the course of history.

Professor Wu Tao stood in front of the stage, turned on his tablet computer, and then a mathematics article appeared on the screen behind him. Fang Hao turned his head curiously, and carefully looked at the content on it.

The title reads "The Global Well-Posedness of the Boltzmann Equation".

"In this paper, I created a brand-new estimation method to address the initial value problem of the Boltzmann equation." Professor Wu Tao said seriously: "This is to prove that the existence of the overall solution of the Boltzmann equation is related to uniqueness."

words fell,

Everyone present was surprised, including Fang Hao.

Pioneering entirely new estimation methods?

When Fang Hao listened to the concept described by Professor Wu Tao, a look of surprise flashed between his brows.

interesting.
"Professor Fang?"

"What do you think?" Academician Kong, who was sitting on the side, asked.

"Uh, I think it's quite interesting." Fang Hao replied seriously: "Prove the existence of an overall solution that satisfies the requirements. This is a very difficult problem in itself. Professor Wu Tao dared to face this difficulty, which shows that he is quite courageous. .”

Just courage?

Academician Kong heard the clues from Fang Hao's words. It is obvious that Fang Hao did not have any expectations for Wu Tao's research report, but he did think about it carefully. Wu Tao's level is there, although he is a bit famous in this field , but want to prove the existence of the overall solution. It is still very difficult, not his level can do it.

Professor Wu on the stage was explaining her own research content, but the elder cousin in a corner of the scene gradually felt a little boring. She glanced at her daughter and fell asleep in the arms of her sister-in-law as expected.

"Hey"

"Qianqian. Do you think Mi Li will get good academic performance in the future?" The elder sister-in-law asked with a worried face: "Look, you have already fallen asleep at the beginning. I am very worried about this little guy now, and his grades will fall in the future. Become the bottom of the class."

Yu Qianqian looked at her little niece who was sleeping in her arms, her chubby little face was undeniably cute, the corners of her mouth raised a slight arc, and she whispered to her cousin: "I don't see any signs of it yet. , but sister, don’t worry, maybe the rice grains will suddenly grow one day.”

"It's a little difficult, isn't it?"

"Rome can't be built in a day." The cousin said helplessly: "I don't like studying so much now, I guess when I grow up."

"Oh, your brother-in-law used to be a salty fish, and he was just eating and waiting to die every day. You see, he has not become the top scientist in the country." Yu Qianqian hurriedly persuaded: "Don't worry, sister. The education of rice grains will be solved in the future. Leave it to your brother-in-law, as long as you are not too bad, you can get into a good university, there is still some face for this."

The eldest cousin sighed, her eyebrows were filled with emotion, and she said to herself: "I have to open the back door even to go to university, can this child be saved?"

As soon as the voice fell,
The cousin asked suspiciously: "Speaking of which, when will your husband save the world?"

"This"

"I don't know." Yu Qianqian said helplessly, "Wait."

Time passed minute by minute, inadvertently. In the past half an hour, Professor Wu Tao stopped his narration, raised his head and looked at the audience, coughed a few times and said: "The most important thing is next, It is also the most essential part of the whole article.”

With a swipe of the stylus, it was quickly turned to the next page. In a certain part of the formula, Professor Wu Tao circled the most essential content in his mouth with red circles.

"This is a brand-new estimation method. In addition to proving the existence and uniqueness of the overall solution, it also proves that it is approaching the corresponding equilibrium state." Professor Wu Tao paused for a while, and then said: "And the convergence rate can be obtained."

words fell,

There was an uproar, and everyone started whispering, including Academician Sun and Professor He on the stage.

"Old He"

"Why do I feel something is wrong?" Academician Sun frowned and said cautiously.

"Well, I feel the same as you." Professor He pursed his lips and said silently: "Didn't you find that Professor Wu has been avoiding a question?"

"you mean"

"Large time asymptotic behavior?" Academician Sun said.

"Correct!"

"Although I don't know if there is any connection, he didn't explain this part clearly." Professor He said seriously.

then,

The eyes of the two looked at Fang Hao who was sitting on the side, who had been silent all the time.

"Professor Fang?"

"What do you think?" Academician Kong asked.

Fang Hao hesitated for a while, and said helplessly: "It's so-so. I'm a little disappointed."

Academician Kong and Professor He looked at each other, and they saw the affirmation in each other's eyes. It seemed that this press conference was a bit of a failure.

"Where is the specific disappointment?" Professor He asked.

"It's almost the same as what you said. The content of the large-time asymptotic behavior does not tell us the specific behavior." Fang Hao said seriously: "From this perspective, it is actually a failure."

"Then can you solve it?" Professor He then asked.

"."

"It's not good to make a lot of noise, isn't it?" Fang Hao said with a bitter face, "If this continues, I'm afraid I will be blacklisted by the academic community."

"No!"

"This is called the pursuit of truth. As you said before, will you tolerate a mistake in front of your eyes?" Academician Kong smiled and said, "Professor Fang, can you solve the problem of asymptotic behavior in large time?"

"Uh, yes." Fang Hao nodded.

Sure enough!

For this answer, Academician Kong and Professor He seem to have known it for a long time. Professor He asked curiously: "How much time will it take?"

"Uh"

"About a few minutes." Fang Hao said solemnly: "I need to combine some fragments in my brain."

In an instant,
The two were a little surprised, even at a loss.

In the two people's cognitive views, Fang Hao's first contact with this problem may take a while to solve, but he actually said that it only takes a few minutes.

at the same time,

After Professor Wu Tao's narration, there was warm applause in the lecture hall, and then the little niece in Yu Qianqian's arms was woken up. She wiped the corners of her eyes with her chubby little hands, looking suddenly sleepy.

"Is it uncle's turn?" Mi Li asked suspiciously.

"You damn girl, why is your uncle all in your eyes?" The eldest cousin rolled her eyes at her daughter, then looked at her sister-in-law, and asked curiously, "Qianqian? When will your husband save the world?"

Yu Qianqian curled her lips and said helplessly, "I don't know maybe."

Before she could finish speaking, a voice suddenly came from the venue.

"Professor Wu."

"Please redefine this part of the large-time asymptotic behavior." Academician Kong said seriously: "We think that the explanation of the large-time asymptotic behavior is not sufficient, and it cannot prove your follow-up content."

As soon as the voice fell,
The originally noisy scene suddenly fell silent.

Professor Wu Tao raised his glasses, and said casually: "Professor Kong, I think there is no problem with this part of the content. This is already the most sufficient explanation. There is no more sufficient content than mine."

Academician Kong shook his head and said seriously: "Professor Wu, please don't question us, especially in front of Professor Fang."

For a time,

Professor Wu Tao was stunned, and the words seemed to be stuck in his throat.

Is there a more adequate explanation than this?
No. Impossible?

the other side,
Yu Qianqian, who was sitting in the corner, had a faint smile on her face, and said to her cousin beside her, "Sister, my husband is coming on stage!"

PS: ask for a monthly ticket, ask for a recommendation ticket
