Tech Hammer

"Ning Wei, are you really crazy?"

"Although Lao Li said it in a vague way, one of the two places is basically yours! You actually refused?"

"You haven't lost your mind, have you?"

"How much effort did you put into getting that guaranteed postgraduate spot, and now you just give up?"

"Don't be so pretentious as the angry youth. These days, the benefits you get are real! Although we all have confidence in you, what if something goes wrong in the postgraduate entrance examination? To say the least, even if you If you pass the exam and go to a school worse than Jiangcheng University, what are you trying to do?"

…

On the way back to the dormitory, I heard Luo Xiang beeping non-stop.

Basically, his mouth never stopped, just like the mouth Ning Wei used when his mother was talking about him.

Although the expression basically means the same thing, the amazing thing is that there are basically no repeated arguments.

God knows that's how this guy did it.

Until the two of them returned to the dormitory and Ning Wei sat at the table, ready to test how far the changes in his mind could go, Luo Xiang continued.

"Ning Wei, you have to think carefully. Jiangcheng University is really good. It's Rebus's alma mater! What's more, your family can't afford you to go through such trouble. What if you fail the postgraduate entrance examination and can't find a good job? manage?"

"You are different from me, you have no old age to chew on!"

Ning Wei turned to look at Luo Xiang speechlessly.

Since when can persuading people come to Versailles?

But he couldn't argue.

After all, he really couldn't compare with Luo Xiang in terms of family environment.

His parents are only contract workers for a state-owned enterprise in a small third-tier city, and their combined income after hard work for a month does not exceed 10,000 yuan.

That's it, there are still nearly five years of mortgage payments to be made.

Fortunately, Ningwei had been sensible since he was a child, and his education hardly cost his family any money. This could support his expenses in college, but his life was still tight.

Luo Xiang is different.

My father is a leader on the railway, and my mother has been running a company on a fairly large scale. In terms of family conditions, Ning Weijia can probably be compared with Ning Weijia.

"Luo Xiang, I've thought about it. If I really can't pass the postgraduate entrance examination, I will eat my brother! Anyway, your family has a house in the provincial capital. I will hang out with you for a year. It won't be a big problem, right?" Ning Wei directly general .

For a good friend who talked about men being righteous every day, Luo Xiang couldn't answer these words.

"Okay, I obey you! I went online. Liu Cong and Mr. Xuan, two unloyal guys, came back and told them that Boss Luo was very angry and the consequences would be serious. Let them consider that in addition to inviting them to dinner, How to make it up to me.”

Luo Xiang threw out this sentence and stepped away.

Of course there are computers in the dormitories, but the internet speeds within the school are impressive during peak hours.

If you are visiting some academic websites, it will be very fast.

But if you want to play games, it will only make life worse than death.

Therefore, Luo Xiang, who loves games and sleeps early, has always been a frequent visitor to Internet cafes outside the school.

Today I made a huge sacrifice to study with Ning Weishang.

Who knew that Xu Ruixuan would come up with such a story? Naturally, it was not very satisfying.

"Okay, go ahead. Remember to come back early." Ning Wei waved his hand casually.

He really needed some quiet time now.

…

When Luo Xiang jumped out of the dormitory, Ning Wei took out a booklet of math competition questions.

As soon as I opened the first question, that familiar feeling came back immediately.

The complete problem-solving ideas are directly engraved in the mind.

This gives me a lot of peace of mind.

At least this ability is not a flash in the pan.

What makes Ning Wei even more delighted is the ability to connect with each other.

Every time you thoroughly understand the solution to a question type, similar advanced questions will automatically flash in your mind, and the solution process will also be given in extremely detail.

Soon, Ning Wei was immersed in this extremely efficient learning process.

In his own understanding, it is normal for him to take the time to digest the questions.

But if Luo Xiang was still in the dormitory at this time, he would see that his roommate was turning the pages of the book faster and faster.

At the beginning, it took several minutes to turn the next page, but in the end, it took only a few minutes to turn the page directly.

If Ning Wei realized this, he might be shocked.

After all, he is not reading a book, but practicing problem solving.

In this way, Ning Wei maintains this efficient state until the goal is to solve problems and answers.

Yes, this exercise book has seventy classic mathematics questions at the front, and problem-solving ideas and answers at the back.

Ning Wei felt confused for a while, followed by a feeling of emptiness.

Subconsciously, he turned around and looked at the dormitory. He was still alone.

That's not right. I looked at the time again. It was only half past nine.

Ning Wei felt something was wrong.

He still remembered that he looked at the time when he came out from the instructor's place, and it was already half past seven.

It takes at least ten minutes to walk back to the dormitory from the teaching building.

He also dawdled with Luo Xiang for a while, which meant that it was at least 7:50 when he started studying the topic seriously.

In other words, it only took him a maximum of 100 minutes to fully master more than 70 classic mathematical problems, and also did derivative learning.

In the past, it would have been very efficient for him to finish this exercise book in two months.

Something magical happened to him, probably related to his sudden fever.

Other than that, he couldn't find any explanation.

It's still very early.

Luo Xiang goes out to surf the Internet and usually doesn't come back until early in the morning.

The multi-functional learning area and learning common space in the general map will not be closed until 10:30 p.m.

In other words, he still has one hour to verify his ability.

By some mistake, Ning Wei logged into the school library through the intranet and found the world's top academic journal - Nature from the school library database.

Basically, large universities have subscribed to these world-class journals for teachers and students to read for free.

But it's all in English.

It was a bit laborious to read, but now this is no longer an obstacle for Ning Wei.

Yes, Ning Wei suddenly had a whim. Now he can draw inferences about other cases when he sees a topic. So what will happen after reading the papers published in the world's top journals?

He wanted to try it.

However, one look revealed big news.

An American scientist named Smith S. Front published a paper claiming to prove that the N-S equation is not unique.

In other words, the uniqueness and smoothness of the N-S equation are proven. A more detailed description is that its three-dimensional global smooth solution has been proved.

This paper quickly aroused Ning Wei's interest.

If this paper is correct, it will be a major event that can subvert the world of mathematical theory and will also have a profound impact on the world of physics.

Not to mention, Ning Wei still remembers a professor who teaches mathematics and physics. When talking about the N-S equation, he also said that the current research on the solution of the N-S equation in the mathematical community has been completely solved in the two-dimensional case, and it has been proved that the short-time smooth solution of the three-dimensional solution exists. .

Why was it suddenly disproven?
