Tech Hammer

Of course, what makes Ning Wei sigh is not only that these children can play, but also that these children are really rich...

Sure enough, most of those who can get into Yanbei University are not economical. The association sponsors directly contribute 110,000 yuan, and the sponsors each contribute 75,000 yuan. With a few more sponsors, millions can be raised in minutes. Not to mention that ordinary college students cannot afford so much money, Ning Wei feels that at least 50% to 60% of young people who have just entered the workforce cannot afford such a large amount of money at once.

But thinking about what he saw in the news, many outstanding students would sign up to go to Antarctica for scientific examinations in high school, and the cost of a trip was often over 100,000, Ning Wei didn't think it was too strange.

There is a difference between the Ning class and the class for gifted teenagers. Many children have received the best education in China during their junior and senior high school years, and there is a high probability that they are not short of money.

Zhou Yanping's words quickly confirmed his judgment.

"... Our classmates in Ning's class are also very wealthy. There are eight people in total, but only one of them has to go to his parents to ask for it because the money on his card is not enough for 75,000. Without this child, we wouldn't know about it. Ning Wei, you How do you think this matter can be handled properly without dampening the enthusiasm of these children? Isn’t it good to let a bunch of half-year-old children manage this money? "

"Have you told the other teachers about this?"

"I discussed it with Lucy and Lao Lu, but Lucy didn't think this was a problem at all. She meant that this was a good thing. As long as the children didn't ask us for help, we didn't have to interfere too much. Lao Lu didn't give anything. I don’t think it’s a big deal. But I think these people have collected hundreds of thousands, and if others are willing to join in the future, there may be millions more. If anything happens because of this money, it won’t be Very good."

After listening, Ning Weili nodded. His reaction to Lucy Ron and Lu Dongyi was in line with their personalities. The former thinks that if students have any good ideas, of course they should be encouraged to do it. The latter has always felt that there is nothing important except mathematics. As long as these children do not delay their studies, there will be no problem...

However, if you think about the problem from the perspective of counselor Zhou Yanping, of course you have to think more.

After all, if something really happened, the blow would definitely hit him first. In particular, he actively fought for the position of Ningban counselor.

"Okay, leave this matter to me. I'll go back and ask them what they think about it, and then I'll figure out how to solve it."

After hanging up the phone, Ning Wei looked at the time. It was already 8:40 pm. According to the military training plan he had seen before, it would take about an hour for the evening training to end. Cell phones were not allowed during training, which meant that he had twenty minutes to think about how to communicate with these talented children about Ningshe.

In fact, there is nothing wrong with setting up a club for future scientific research in the eyes of the teachers, but the money paid by this club is obviously too much. It’s really scary for students to take out tens of thousands of dollars at a time.

But then again, Ning Ban's scholarship can indeed support the membership fee, and if it is really necessary to incubate the project, the money is actually not much. If many projects do not receive support from schools or professors, it will be difficult to complete them with the strength of students alone. Money is a big problem.

Even in the school's laboratory, students are charged for doing some experiments for their own projects, including using supercomputers, and they may have to queue up. The more expensive the instrument, the higher the charge. Although your own school certainly has various preferential policies, if there is no professor’s endorsement, your application may not be approved in many cases.

From this point of view, Ning She’s original intention is definitely good. It’s just that I haven’t thought about doing this in my freshman year. If these kids had this idea when they were in their junior year, Ning Wei would feel that it was really something.

By that time, the children suitable for future research have almost been screened out. It is feasible to use this bonus to try incubation projects, and there is nothing wrong with letting these children know the difficulties of scientific researchers in advance.

Ning Wei still thinks of these children too simply.

In his opinion, these children established Ningshe just to incubate mathematics projects within Ningshe. In fact, Chen Diancheng had considered various natural science projects from the beginning. If the management of Ningshe was optimistic, they could invest in and encourage them, and even some It's similar to an investment bank. The only difference is that when an investment bank invests in a project, it mainly depends on whether the project can bring benefits, and they look on whether it can promote China's scientific and technological progress...

Obviously Ningshe is far more ideal than investment banking.

Twenty minutes passed by in a flash, and Ning Wei had probably figured out how to talk, so he took out his cell phone and called up Ning's small group.

It was still the same group of students he thought had potential before. There were no other teachers and sixteen students in it, a total of seventeen people. The proposer and initiator of Ning She are all in this group, so Ning Wei is too lazy to start a group to talk to a few people about this matter.

After opening the group chat, Ning directly @everyone and asked: "I heard that you are planning to set up a Ning Club recently? Is this a thing?"

There was a response soon, and soon a cat-headed question mark animated emoticon appeared: "What are you talking about, boss? Why does it sound so awesome but I don't know it?"

Ning Wei glanced at March on the screen. Apparently this animated picture was from the set of March emoticons.

Since starting to popularize science to the public, March’s emoticons have become popular. Similar pictures like Ning Wei know that there is an exact same picture, but the edited copy in that animated picture is “How can there be a meow in this world?” Things you know?”

Anyway, it looks pretty cute. Well, cute emoticons are one thing. When I saw this picture, I felt like I was being careless. I thought that the execution efficiency of this group of genius children was very high. At this time, at least the outstanding students in his mind already knew about Ning She. It seemed that he was overthinking.

But Ning Wei quickly forgave himself, at least he didn't talk about it in the class group...

Fortunately, it didn't make him feel embarrassed, and the instigator quickly responded to the message. Young people seemed to particularly like to talk through pictures first. Chen Diancheng sent a shy dynamic smile, and the way his little hands scratched his bare forehead looked quite cute. .

After posting the picture, the founder of Ningshe sent a message: "I also emphasized to everyone that it should be kept confidential. Unexpectedly, Professor Ning found out in less than ten hours!"

"It's hard not to know. How should I put it? I think Ningshe's original intention is fine, but don't you think it's too early to invest in scientific research? In fact, you probably don't have much idea about scientific research yet. , many times it’s just based on imagination. How can real scientific research produce results so easily? If you are willing to listen to my advice, you should put your energy into learning first."

"Especially the freshman and sophomore years are the stage when you are laying the foundation. If you focus mainly on the management of Ningshe at this time, how can you ensure that your grades can meet the standards? Advanced mathematics is still difficult! Especially when you join the society The fees are still so high, and managing the money will definitely distract your attention from studying, and choosing good projects will also distract your attention, so don’t you think that the establishment of Ningshe is a little early?”

Seeing that the culprit was exposed, Ning Wei began to give earnest advice.

The copywriter didn't let San Yue take action. He had already thought of the content in the past twenty minutes. He quickly edited two paragraphs and sent them out.

" @Professor Ning, that's wrong. Our establishment of Ning Club will not conflict with our studies. Moreover, we have actually studied many courses in our freshman year by ourselves, so there is definitely no impact on our studies." The person who answered for the first time was Wang Xiwen, the deputy squad leader.

"That's Professor Ning. Don't underestimate us. We are the students you selected. We have already mastered many basic mathematical things."

"Self-study +1."

"Self-study +2."

…

"Self-study +12."

When Ning Wei saw these words, he suddenly felt that the children in Ning's class were a little too proud. Do you think mathematics is too simple?

This is still military training, so many people dare to say that they have already studied the freshman courses by themselves?

After thinking about it, Ning Wei decided to educate these children with facts. After thinking about it for a moment, a question appeared in his mind.

"Have you taught yourself? Okay, then I will give you a question first to see how effective your self-study is. The question is as follows: Suppose f(x, y) has a continuous second-order partial derivative on R, satisfying f(0, 0 )= 0 and fxx+fyy=x2+y2. Use Cr to represent the circle with the center at the origin and radius r. Find the average value of f(x, y) on Cr A(r)=12πr∫Crf(x, y)ds, where the integral is a curve integral of the first type.”

This is a mathematical analysis exercise. The question itself is not too difficult, but it tests students' ability to understand mathematical concepts. But that is for students who have studied mathematical analysis and advanced mathematics.

He is not afraid of these children cheating. Now these children are in military training. No one will bring a big book with them, and even if they want to cheat, it is impossible. This is a question he made himself. Even if he searches for the same question on the Internet now You also need to understand the question types in order to answer them correctly. Of course, Ningwei would not wait that long. As long as no one does it within ten minutes, they can already tell them that mathematics is not as simple as these children think.

Sure enough, the group was quiet for a moment, but...

“A(r)=12π∫2π0f(rcosθ,rsinθ)dθ

=12π∫2π0dθ∫r0fx(ucosθ,usinθ)cosθ+fy(ucosθ,usinθ)sinθdu

=12π∫r0du∫2π0fx(ucosθ,usinθ)cosθ+fy(ucosθ,usinθ)sinθdθ=12π∫r01udu∫x2+y2=u2fxdyfydx (second type curve integral)

=12π∫r01udu∫∫x2+y2u2fxx+fyydxdy=r^4/16. The result of this step is to first use Green's formula and then polar coordinate transformation. Are you right? "

Chen Diancheng was very fast. Ning Wei took a look and found that it only took Ning, the squad leader, about six minutes to solve the problem and type.

But this is not over yet...

"Class Leader Chen is really fast, but my solution method is different from Class Leader Chen's. Professor Ning, let's see if this is the solution..."

"I also thought of a solution..."

Soon, a total of nine people gave their own answers, using three different solutions. Although the speed was faster and slower, the details were still slightly different. Ning Wei felt that no one could solve it and still insisted on answering. of……

Of course, this is enough to show that these children have already studied the freshman courses by themselves and are not kidding him.

It felt a bit like being slapped in the face, but actually the mood was quite pleasant. This also made Ning Wei feel very emotional. These children in Ning's class are really much better than he was back then. At least he was asked to do this kind of math during military training. As for the analysis questions, I guess I can’t even understand the question.

But the problem was that this exhortation failed so badly that he didn't know what to say for a while.

"Yes, yes, this shows that everyone has really studied on their own, but being able to do this basic question type does not mean that you are capable. I am giving you an advanced question type..."

…

In this way, both parties seemed to have forgotten the purpose of this chat and began to discuss some topics that needed to be studied in the freshman and sophomore years.

From Ning Wei's point of view, he couldn't deliberately make things difficult for these children, so most of the questions were based on the knowledge points such as advanced mathematics, linear algebra, composite functions, etc. learned in college. It is not good to let these students take the test on obscure and complex topics such as Lie algebra and functionals before they have even started formal study.

The effect cannot be said to be bad. At least there are fewer and fewer children who can solve the next two questions. However, Chen Diancheng and Wang Xiwen obviously have very good results in self-study, or they are so spiritual that ordinary questions are really good. It was hard for the two of them. Even though the results of the third question were both wrong, the overall solution was remarkable, which made Ning Wei a little speechless...

Just as they were about to ask the fourth question to let these two guys know the depth of college mathematics, someone suddenly posted on WeChat: "The instructor is here."

Only then did Ning Wei realize that these children were still in military training.

"Forget it, let's get here today and talk about it tomorrow. You guys go to bed quickly. We have military training tomorrow."

After sending this sentence, Ning Wei put down the phone in frustration.

After thinking about it, I felt that I couldn't be the only one feeling frustrated, so I picked up my phone again, took screenshots of the questions he asked in the group today and the problem-solving process posted by classmates on WeChat, and then sent them to the group of my roommates who were once at Jiang University. . Then he said with emotion: "Hey, these are the questions solved by the children in Ningban who are still in military training and have never attended a day of class. There are three questions, one is mathematical analysis, one is linear algebra, and one is about derivatives and differentials. These kids We can actually do it all. Compared with them, we were really scumbags when we were freshmen!"

As the core figure in the dormitory group, Ning Wei's news has always been focused on.

Especially at a few minutes to ten o'clock on non-weekend nights, when everyone has free time.

So soon three neat "?" appeared in the group chat.

"Professor Ning, what are you talking about? Let alone my freshman year, I can't even ask these questions for me now." After posting the question mark, Luo Xiang immediately gave his opinion.

"That's right, Professor Ning, you underestimate us too much. You make it sound like we will do the same thing after graduation. If you weren't still in the group, I would have almost forgotten that my university is in the School of Mathematics." Mr. Xu The second last hit.

"Ahem, I can still do the first and second questions, but the third question is a bit detoured... It's over, two years after graduation, all the things I learned before have been returned to the professors... Ning Ban is really too powerful! "Liu Cong still showed his half-hearted temperament as always.

…

Ning Wei only felt that his enthusiasm was waning. These screenshots were intended to arouse the shameful emotions of these former roommates, but it was obvious that a few of them did not feel too much and were not ashamed. Some even felt proud instead of being ashamed. It was a perfect proof. There is a saying that if you are shameless, you will be invincible. Too lazy to pay attention to these three guys, Ning Wei once again opened the instruction set he was studying.

In fact, in this world, two-dimensional silicon chips have almost reached the limit of Moore's Law, which also means that the performance of general-purpose processors has almost reached its limit. For the market, demand is basically saturated. Even Intel's own development of Intel IA64 for the high-end server market failed to attract attention in the market due to various problems, let alone other instruction sets.

PowerPC, which also focuses on the high-end server market, is backed by very large companies such as IBM and Apple. It once had a glorious time, but because a single host provided super performance, it has gradually been replaced by a cluster composed of a large number of cheap x86 servers. The replacement of the host market by clusters directly led to an increase in development costs, and the development power began to weaken. In the end, Apple's Mac had to give up PowerPC and move to x86.

To put it bluntly, developing instruction sets nowadays is a thankless task. This is why a group of people insist that they can buy other people's instruction sets for their own use. The market demand has been met. It is said to be a technical problem, but in fact it will eventually be transformed into a market problem. The simplest one is the operating system.

The instruction set at the mobile phone level is okay. Huawei's Hongmeng system has already reached scale, especially this generation of smart upgrades, which has further expanded the influence of Hongmeng system. But at the PC level, designing a new instruction set to use Windows requires the cooperation of Microsoft. If Microsoft does not cooperate, then the new chip will require a new operating system to cooperate, which is troublesome.

This is why Ning Wei didn't want to take care of this matter before and temporarily refused to call professionals to have a meeting together. Because he actually doesn't have a complete idea at this time, he must make his own instruction set, otherwise he will be restricted in everything in the future. After all, he was used to people smiling at him, so he no longer had the ability to lower his face and ask for help.

If a new operating system is to be built, in theory, the market size of Greater China is enough to carry it. Since some people also think that China must have its own instruction set, it also means that they must have considered the issue of the operating system. .

There are no meetings or meetings for the time being, simply because I don’t want my own thoughts to be imprisoned by other people’s thoughts.

so……

It's really difficult...

…

At the same time, the outstanding students in Ning class also felt that it was too difficult for them.

They were really discussing the topic with Professor Ning. How could the instructor say that they violated discipline and were still playing with their mobile phones when they should be sleeping?
