Chapter 577 Your husband is actually very powerful! Ask for a monthly ticket~)
Song Yuxi was sitting on the edge and was shocked when she heard the conversation between the two. Good guy...are these two mothers too irresponsible?
"Hey Hey hey!"
"Can you two... be fine?" Song Yuxi said helplessly: "Is it necessary? We are all sisters... Okay, okay, you two, please stop making trouble. The conflicts between adults involve the children.
Besides...if the children don't like each other in the future, wouldn't it be in vain now?"
"snort!"
"My son is definitely a millionaire..." Liu Yun'er said proudly, "The kind of handsome guy that everyone loves!"
"cut..."
"That's all your wishful thinking." Guo Li said angrily: "Hurry up and call your husband out... I will find the equation set now and let your husband solve it... But set a time limit, two
Hours... If the problem is not resolved within two hours, your husband will lose."
"no problem!"
Liu Yun'er nodded and hurriedly shouted to the study: "Husband... Husband, stop playing games and come here quickly... My mother-in-law has spoken. She wants to give us a dowry of 10 million yuan, plus a big villa!"
As soon as the words fell,
Lin Fan walked out of the study and asked curiously: "Who is it? Which one is stupid?"
"..."
"Lin Fan, please speak to me!" Guo Li said with a dark face: "Besides...it's not certain who will give the dowry! What if you give me a dowry of 10 million yuan and a large villa?
No, Tianyu... stop playing around and give it to me too!"
Immediately afterwards,
Three grown men came to the living room. At this moment... Lin Fan, Wu Tianyu and Zhou Feng looked at their wives with confused faces.
"Is such that!"
"Lili doubted Lin Fan's mathematical ability, and then asked you to solve a system of equations that she couldn't solve. At this time... Yun'er said that it can't be solved in vain. If Lin Fan solves the system of equations, let Lili
When you give birth to a daughter and marry your son, the key is not to give a bride price, but Lili will give a dowry of 10 million yuan and a large villa."
"But if Lin Fan doesn't solve the problem, then if Lili gives birth to a son, your daughter will marry Lili's son as his wife. At the same time, Lin Fan, you will have to give her a dowry of 10 million yuan and a large villa." Song Yuxi explained.
: "About...it's like this."
After listening to Song Yuxi's narration, Lin Fan nodded and said seriously: "So that's it...I understand."
"mother-in-law..."
"You are so generous." Lin Fan said with a smile: "Not only do you not ask for a betrothal gift, but you give your son-in-law a dowry of 10 million, plus a large villa. In this case... why don't you give me another car, all at once?"
Forget it."
"OK!"
"I'll give you a Mercedes-Benz!" Guo Li raised her head and said with disdain: "But...my father-in-law, it's hard to say now...you only have two hours. If you don't finish it within two hours,
, I'm sorry...then I have to do the opposite."
"hehe!"
"In other fields... I don't dare to vouch for it, but in the field of science, I, Lin, am still quite capable." Lin Fan patted his chest and said confidently: "I'm going to get some paper and paper right now.
Pen, you finish the question...and then start the timer!"
Immediately afterwards,
Lin Fan brought a stack of copy paper and two pens. When Guo Li got the paper and pen, she immediately wrote down a system of equations and handed them to Lin Fan.
Timing begins!
After Lin Fan got the white paper with the equations written on it, he immediately fell into confusion... The equations in front of him seemed to be changed from the most important basic equations in inviscid fluid dynamics...
To be precise, this is a system of differential equations of motion.
Damn it!
Isn't this... so damn difficult?
Lin Fan sat on the sofa, holding the blank piece of paper, but he didn't start writing for a while... he just stared blankly for a few moments, and then frowned, because this system of equations not only has continuity, but also
When it comes to fields, there are differentiable situations that need to be derived from the principles of mass, momentum conservation, and energy conservation.
certainly,
If it were just like this, Lin Fan wouldn't be so confused. The key is... a finite arbitrary volume must be considered, which can be fixed in space or move with the fluid.
at this time,
Liu Yun'er was sitting on the edge. Although her face was expressionless...but she was actually extremely nervous. She didn't understand the mathematical problem provided by Guo Li at all, but through the analysis of her husband's expression
, it seems...the invincible husband is stumped.
husband!
Come on! The children are watching!
Liu Yun'er stroked her belly and said silently in her heart...Xiaotong, Xiyun, come on daddy!
at the same time,
Wu Tianyu sat next to Guo Li and looked at Lin Fan nervously. Then he carefully approached his wife's ear and said softly: "Fanzi... Fanzi seems to be stumped. It's been five minutes."
, still with a frown on his face."
Guo Li did not speak, and her expression was slightly arrogant. She never thought that she would lose, because this problem originated from a variant of one of the most difficult mathematical formulas. Its existence is to solve the supercritical problem of global regularity.
state.
Without in-depth research in this area, it is impossible to solve it... It requires abstract methods, pure harmonic analysis, and relatively special geometry to have a chance to explore the threshold of solution.
As for Lin Fan...forget it!
It's impossible for him!
The other two people in the living room, Zhou Feng and Song Yuxi, stood behind Lin Fan, looking at the question in his hand, with helplessness written on their faces. In fact, they didn't understand it, but judging from Lin Fan's demeanor,
,basically...cool.
Time passed by minute by second, and the few people present did not make a single sound. They looked at Lin Fan quietly and looked at this man in a daze.
During this period,
Lin Fan tried many methods in his mind, but every time he wanted to go further to find a solution, he would encounter an unsolvable dilemma, which is whether there is a smooth solution to this system of equations. If it is not proved,
You can't proceed at all later.
Thinking for a long time,
Lin Fan suddenly picked up a black pen placed on the coffee table, then picked up a piece of copy paper and began to solve the problem on the paper.
this moment,
Everyone's eyes were attracted by the process he wrote, although... only one person could understand what Lin Fan wrote.
Swish, swish, swish... After writing for less than three minutes, Lin Fan stopped writing, silently reached out and took out a brand new piece of copy paper, and solved the problem again... As a result, this time he only lasted for a while.
Minutes later, he declared failure, took another piece of paper, and continued to solve the problem.
As the saying goes, laymen watch the excitement, while insiders watch the door.
In the process of Lin Fan's continuous solution, Liu Yun'er, Zhou Feng, Song Yuxi and Wu Tianyu only saw Lin Fan repeating one action and enjoying it. However... As a top expert in the field of mathematics, Guo Li
But I felt a little surprised.
hiss!
I have to say...it's really awesome!
He actually figured out the core concept of the system of equations in just half an hour. He... Everything he is doing now is laying the foundation for solving the supercritical state of the global regularity problem.
At this time,
Guo Li suddenly realized that the man in front of him who was constantly solving problems had very terrifying mathematical abilities. Without anyone reminding him, he had already figured out the core concept of the system of equations in half an hour.
In the whole world...I'm afraid he is the only one who can do it.
"..."
"That's not right..." Lin Fan put down the black pen in his hand, spread all the papers on the coffee table, frowned and said to himself: "This general explanation... doesn't exist?"
The so-called general solution means that it can be proved that the solution to the system of equations always exists. A more precise analysis means that the system of equations can be used to describe the solution under any conditions. For Lin Fan... this system of equations is connected to mathematics.
It was difficult to explain the theory, and he had to prove the existence of a general solution, which made him very desperate.
Guo Li also looked at the paper on the coffee table, the process that Zhang Lin Fan tried to solve, and then...she was refreshed her world view. Although each piece of paper looked the same, there were actually huge differences, because Lin Fan
Every time the solution is solved, it is a new... concept.
Oh my god!
This...is this awesome?
The essential...
Guo Li looked at Lin Fan with surprise on her face. In these forty minutes... he actually surpassed what he had achieved in three months.
"I'm going to the balcony to smoke a cigarette and think about it." Lin Fan said nothing, stood up silently, and went to the balcony alone.
Liu Yun'er looked at her husband's back and couldn't help but pursed her lips...
Could it be...
My invincible husband...is going to fail?
"that..."
"Lili... how about... let's... forget it?" Liu Yun'er bit her lip and said softly: "I saw Lin Fan... hysterical and helpless, I
...I feel quite uncomfortable.”
Hearing Liu Yun'er's words, Guo Li, who was about to refuse, instantly softened her heart. She nodded silently and said, "Well...actually...your husband is really powerful, beyond imagination."
Even though he wrote so much waste paper, the content above surpassed what I had accomplished in three months."
Speaking of which,
Guo Li sighed and smiled bitterly: "You may not know... This system of equations is modified from the basic equations of ideal fluid mechanics... It is a variant, and it exists to solve the supercritical state problem."
"Is it difficult?" Song Yuxi asked.
"It's not very difficult...it's very, very, very difficult!" Guo Li said seriously: "Currently...no one in the world can solve it..."
Before Guo Li could finish speaking, Lin Fan hurried back, his face filled with some inexplicable excitement.
