Hammer of Technology

Therefore, the questioning by media people on CNN's official website was immediately removed from the shelves, and a large amount of money began to flow into leading technology stocks such as Facebook, Google, Microsoft, Apple, and Intel. These small companies that are not on the table for the time being have little impact on the overall market, and at most they only affect the highly hyped Metaverse concept sector.

There is nothing wrong with releasing some water. After all, the stocks of these companies have already been stretched more than ten times this year. Make a move, find a good reason, and still continue to stir up speculation.

For Bernie Cushing, of course, he succeeded, and it was a major success.

The layout was made two months in advance, and heavy bets were placed on the short positions of these leading stocks in the metaverse. This wave of plummeting, coupled with the operation of more than one billion dollars today, made a mad profit of more than 40 billion dollars in one day.

Looking at the current market, whether it is Soul, Roblox, WIMI, or other companies in the supply chain, the downward trend cannot be reversed, so his wealth will still increase.

Not to mention much, Bernie Cushing felt that when this wave of market ended, he could get at least [-]% of the profit. According to the contract, the bonus he could get would not be far off, even if it wasn't [-] million.

He won the bet!Satisfied enough!After all, everything was developed too hastily, so he didn't have time to complete the entire layout.

However, people's luck is so strange sometimes. When Bernie Cushing himself felt very satisfied, when there was only half an hour left before the end of the last trading day in September, another shocking news came through the Internet. Pass to Wall Street.

Packaging factories in the global chip industry are almost considered immune to major disasters. An earthquake near Penang, Maya State, is said to have a magnitude of 7.0Ms on the Richter scale. The chip packaging factory was damaged on a large scale due to the earthquake, and the semiconductor packaging factories in other places were also affected to varying degrees. The specific loss is unknown...

When Bernie Cushing saw the news pop up on the computer screen, he was stunned for about a second...

Then I saw a large number of sell orders suddenly appearing in the technology sector that had just stabilized. The large buy orders that were previously hung on the trading interface were sold or withdrawn almost instantly. Affected by this news, the entire technology sector started a cliff-like decline again... …

This time it’s really not just the metaverse sector, the entire technology sector includes smartphones, new energy vehicles, aerospace... All industries that require chips have started to fall almost at the same time...

Really, at this moment, Bernie Cushing feels like he is dreaming!

203 Lovely March

What does it mean that the house leaks and it rains all night, that's probably it.

The black swan incident that suddenly popped up on Friday had already made the entire technology sector of the US stock market extremely vulnerable, but when the market was about to close, such heavy news suddenly came out!This is not an earthquake, this is the bad news that rings in the ears of technology companies all over the world.

It is no exaggeration to say that the entire modern scientific system is built on chips.In addition to the most familiar CPUs and GPUs, there are also various radio frequency chips that form the basis of network communication, various electronic control units, sensor chips and multimedia chips that are widely used in automobiles, modern aircraft of all types Not to mention, especially for civil aviation aircraft, various modern electronic control systems require a large number of chips...

Chip packaging and testing is the last very important step before chips leave the factory. Ma Yaguo occupies about one-third of the global market share, especially in Penang, which is known as the Silicon Valley of the East. In addition to the chip packaging and testing industry, including Apple, Micron, Broadcom, Infineon, Samsung and many other world-renowned giant technology companies have set up factories here.So this shock definitely shook not only the houses in Penang, but also the financial market in the global technology circle.

When the entire U.S. stock market and the entire technology sector began to experience a flash crash, the metaverse concept sector, which had already fallen to the point of crying, became even more fragile. The sharp drop in the technology sector also directly drove the entire market index to begin a rapid plunge. , So this Friday, the market will be closed early at 3:26 pm New York time and 3:26 am China Beijing time.

No way, in just over 20 minutes, the Dow has plummeted by 7.2%. According to the circuit breaker rules, the market has to suspend trading for 15 minutes. However, this time is approaching the market close, so everyone can get off work early.

Countless people have suffered heavy losses, but this also happens to set off the thriving of some people.

For example, Bernie Cushing, after the market closed, he was liquidated and settled, and his profit has almost reached 80%.What is this concept?If all the funds under his control were liquidated, the more than 200 billion US dollars would have increased to more than [-] billion after this day, and it only took one trading day to achieve this goal.

While he was still in a daze on the chair, his team had already started a carnival, and he could even hear the sound of champagne popping from the office upstairs...

"Bernie! Why are you still in a daze? We won, we won the bet, my God, thank that Huaxia boy, thank the Penang earthquake, thank God, we won!"

"Yeah, we won! We really won! Haha... Won! Going to the party tonight, all expenses will be on me... We should have a drink for that Ningwei, really! I won! Bernie Cushing finally came to his senses and jumped up, waving his fists.

At this time, Bernie Cushing was already in ecstasy. It was not as simple as making money. He believed that after today, the whole Wall Street would know his name. This was the most exciting thing for him!And pay tribute to his idol Michael Borui!

……

The news quickly spread back to the country. For many investors who stayed up all night to pay attention to US stocks, many people were also confused. It was almost time for the market to close. Suddenly there was a circuit breaker?Earthquake in Penang?Is it such a coincidence?

After the last trading day of the US stock market in September finally came to an end, major financial forums were lively again for a while.

But after all, it was already past three o'clock in the morning in Huaxia, and even though the next day was a National Day holiday, not many people were still sticking to their computers.But even so, the hot topic of public discussion is still from the Penang earthquake to Ning Wei.

After all, Black Friday, which is so rare in history, was Ningwei’s first shot. If it wasn’t for Ningwei’s Weibo post, it would have directly caused the U.S. stock technology sector to dive sharply early in the morning. There is a high probability that it will not be blown directly.

So in the middle of the night, the topic about Ning Wei was fired again.

"Really, follow Ningwei Weibo. I think he may not know when the stock market will rise sharply, but he must know when the stock market will plummet!"

"It's a pity, I'm still eating technology melons in broad daylight, and I didn't notice anything wrong at all! I turned a blind eye to such a big bad news, and even if I didn't make a big profit in this wave of market, I even lost several W Nothing else, I have already paid attention to Ningwei, and I will believe whatever this boss says in the future!"

"Before today, I only thought that the investigative reports of short-selling agencies were awesome. Usually, whoever reported them would die. Now I find that there are still people who can be so awesome, posting a Weibo to kill an entire section! See you soon , see you soon!"

……

In this way, in Meimei's dreamland, Ningwei's reputation has inexplicably increased, and it has directly crossed borders and started to affect the financial circle.Maybe Ning Wei himself doesn't really believe it. Now that he is posting a Weibo, few people may believe that someone's stock will rise sharply, but if he says that someone's stock will plummet, probably many people will believe it.

Of course, it is estimated that killing Ning Wei would never have imagined that the biggest beneficiary of his post on Weibo is probably his little milk cat—San Yue.

……

In the United States, a unique video conference is underway. Most of the participants are bigwigs from technology companies, financial giants from Wall Street, and shareholders from many well-known private universities in the United States, including Harvard, Yale, MIT, and Princeton. , Stanford University, University of Pennsylvania, Columbia University...

In addition, there are also the chairman of the American Mathematical Society, the controllers behind several famous journals in the United States, and computer experts, etc. A total of more than 20 people gathered in front of the video at this time.There are scholars among them, but not many. Many of them are scholars, but at the same time they also have massive resources.

If Ning Wei knew that so many bigwigs had held this video conference just for him, he would probably feel very honored.

Yes, so many bigwigs gathered to discuss Ning Wei.

"This incident has sounded a wake-up call for us. Some people should not give him too much power to speak. This is a mistake, gentlemen and ladies, this is a huge mistake! I can't believe it, a Huaxia Young people who have made a little bit of academic achievement can trigger a shock in the stock market just by making some inappropriate remarks in public! This is something that has never happened in American history! It is a shame to everyone! "

"This is the first time, and it will be the last time. This kind of thing must never happen again! I heard that some people think that he should be awarded the Wolf Prize. I don't know what other people think, but let me To be clear, I don't think this is right! Or before he becomes more mature, or grows into a scientist we can fully trust, we shouldn't let a young foreigner who doesn't know how to restrain himself be able to have in our country Too much influence! Even if his achievements are very fruitful, do you understand?"

The voice of the old man who spoke was not loud, but everyone knew the weight of this big man, because he could almost represent one of the most powerful institutions in the world - the Federal Reserve.

It is almost because the old man is not the chairman of the Federal Reserve, but one of the seven members of the Federal Open Market Committee with permanent voting rights, but many times what he says is even more weighty than the chairman of the Federal Reserve. If it is inconvenient for the chairman of the Federal Reserve to say something, he will say it without any scruples. After all, he is currently the longest-serving member of the committee.

After a long silence, someone still spoke: "Your Excellency Sackler, I can understand your concerns, but the academia has its own set of operating rules. If the achievements of a certain scientist are arbitrarily wiped out, our entire system may be lost." The original credibility. Especially some things happened before, which made Ningwei have a high prestige in the eyes of the younger generation of students, so I think what can be done is to try to downplay the influence of a young genius. Or today’s conversation should let Are those irresponsible media bosses here to listen?"

"Of course, this suggestion is very good, and I also think it is necessary. But before that, don't you think we should also take action? I believe that academia has its own operating rules, but I don't believe in the achievements of that young man It can make you helpless, and I believe that any academic research needs financial support. Without funding, no matter what research projects you research, you will eventually die, am I right?" The old man said calmly and softly , still maintaining a peaceful tone, but there is an undeniable taste in the tone.

"Actually, can this be the case? I probably understand Professor Compton's worries, but as Mr. Sackler said, no one in this world is irreplaceable. We can try our best to solve it in a less controversial way." This question. For example, I heard that a mathematician appeared in China recently who has caused great repercussions in the mathematics circle, and I heard that her latest paper was also favored by many people. Well, I don’t remember her very well. name..."

"You should be talking about March, Mr. Aiken." Someone pressed the microphone in the video and gave a hint.

"Yes, yes, it seems to be the name. Maybe we can get in touch with this March to get a general understanding of her thoughts, and we can even bestow some honors on her. And coincidentally, they are all Chinese, as long as If the publicity is done well, maybe March can become a new academic star, replacing Ning Wei in the hearts of those lovely young people. Of course, as I said before, you should contact that March first. If She really showed some achievements, and she can accept our kindness, why not? Of course, I am just making an example, if there are other mathematics emerging, of course we can also highlight them, Professor Compton, what do you think Woolen cloth?"

The professor who was asked thought about it and replied: "Well, this may indeed be a good solution."

Hearing this answer, Aiken smiled and said: "Of course, this is just an alternative, and we should focus on our own people. It will be more natural if our scientists can achieve some reasonable achievements in the next period of time." Okay. Of course, it seems that time is running out of time, but as Mr. Sackler said, any controversy in this world will eventually subside. It's just how we choose to do it."

In the video, many people began to nod their heads, and the old man nodded at this scene and said: "Well, it seems that we have reached a consensus. Gentlemen, I do not intend to judge the academic field, but there are some things we cannot sit on." Watch it happen and ignore it. Yes, I don't understand the rules of your academic circle, but I understand the rules of this world. For example, I believe that there may be some abnormal people in this world who don't care about money, but I believe such people It must not be too much, everyone agrees?"

Many people had smiles on their faces, yes, who in this world would not love such a lovely thing as money?

"So I'll leave it up to everyone. In addition, I think Mr. Aiken's suggestion is very practical. You can do your best to conform to your rules and make everything look fair and just. After all, we can't hurt too many people The hearts of motivated young people. But if this is really not possible, I don’t think it matters. At least we can teach them that fairness and justice in this world can actually have many interpretations. The most important thing is that the right to interpretation is ultimately In whose hands is it held. Don’t worry too much about the so-called credibility, the foundation and essence of credibility is strength, what do you think?”

No one said anything, and naturally no one objected.

"Well, it seems that we have reached an agreement. Then do as Mr. Aiken said. I, an old fellow, will not waste everyone's time! I wish you all a happy weekend."

……

Ning Wei didn't know that when he was sleeping, the bigwigs on the other side of the ocean reached some consensus on him, and these opinions finally turned into an email lying in March's mailbox.

March, who didn't need to rest, also read this email for the first time. After careful thinking, judgment and analysis, March responded with a reply letter that echoed her style: "I can feel your sincerity. , but will you give me a big house to live in for free?"

Soon, she received another email reply: "Dear Professor March, as the last letter said, we will provide you with the most superior research environment, first-class salary, and naturally the best living conditions .If you are willing to serve as a professor, we can immediately send you a formal job invitation letter."

On this kind of problem, March did not disappoint the other party, and soon an email was automatically generated again and sent over.

"This is great, I am very satisfied with the conditions you have given. But I need to complete the ongoing tasks first and get the consent of my family. It will take some time. Are you willing to keep this wonderful job opportunity for me? ?”

Undoubtedly, the attitude expressed in these replies is enough to make many people think that although March is a bit poisonous, she is much cuter than Ning Wei!

204 An Applied Method of Mathematics in Love

Holidays make people happy, travel makes people happy, and love makes people happy. When these three things happen at the same time, it is the three-dimensional happiness.

I got up from the bed at six o'clock in the morning, and took a shower happily. After washing, I put on my beloved youth clothes, looked left and right in the mirror, and ran into the study after feeling perfect. Sanyue said hello, of course it was a simple greeting, and left a sentence: "I'm going on a date, you are good at home!"

Then he turned around and walked out of the house in a chic way, and arrived at the women's dormitory downstairs at seven o'clock on time at the appointed time. To his surprise, Jiang Chenshuang was already waiting for him at the door.

Apparently, the girl also dressed up a bit. The clothes were "work clothes" chosen by Yu Xingwei. Inside was a beige sweater, matched with a camel long coat, paired with a pair of light blue jeans and a pair of simple sneakers. It looks youthful and fashionable.

Although Yu Xingwei was not there at this time, Ning Wei still gave him a thumbs up from the bottom of his heart. To be honest, he admired Brother Yu a lot. Although he usually behaved very straight, when it came to choosing clothes for girls, It's quite appreciative.

What Ning Wei didn't know was that it didn't really have much to do with being blind. Yu Xingwei just picked a similar brand store at random according to the fee Ning Wei gave, and then told the girls and sisters who sold the clothes what he wanted. All the clothes and collocations are actually referenced by those ladies...

This probably also confirms the fact that professional matters must be handed over to professional people in order to be worry-free and happy.

"What are you looking at?" Although the two had confirmed their relationship, Jiang Chenshuang still couldn't bear Ning Wei's fiery gaze.

"I think you look like my future wife!"

Ning Wei gave the standard answer in his heart in a serious manner, his tone was as serious and serious as talking about a math problem, which made the girl lower her head again, and then Ning Wei took a natural step forward and took the beauty's little hand and complained: "It's all agreed. What is there to be shy about? By the way, have you completed all the study tasks?"

"Hmm!" Classmate Jiang responded.

"That's fine. You can ask me if you don't understand anything about advanced mathematics and line generation. You can ask me later on the way, but you are not allowed to ask me when you get to the place. You have to relax when you are playing." Ning Wei said.

"Oh, the adjoint matrix problem of linear algebra, I read the book but still don't understand it very well." Jiang Chenshuang said honestly.

Ning Wei nodded, and replied: "Adjoint matrix? Well, when you encounter problems with adjoint matrix, you have to memorize some formulas. Let me tell you, now the professors in the Mathematical Academy will not give you a pure The problem of adjoint matrix is ​​generally combined with the inverse matrix to set the test points, and this kind of problem has a certain characteristic, and there are many solutions. I will teach you the most tricky solution. Calculations are all analyzed from the formula aa^*=a^*a=|a|e."

"Some conclusions can be used directly, such as if r(a)=n, then r(a^*)=n, if r(a)=n-1, then r(a^*)=1, if r (a)<n-1, then r(a^*)=0. Let me give you an example, let a be a non-zero matrix of order n, a^* is the adjoint matrix of a, when a^t=a^ *, prove that |a| is not equal to zero. How do you think about bringing it into the formula just now?"

Jiang Chenshuang blinked, and suddenly found that a few words from Ning Wei seemed to make the problem that had been bothering her less difficult, so she thought for a while and replied: "Oh, then you should directly substitute a^t=a^* into aa^* =a^*a=|a|e, get aa^*=aa^t=|a|e, and then use the method of contradiction, set |a| equal to zero, set the row vector of a to αi, in this case αiαi ^t is equal to zero, so a is equal to zero, which contradicts |a| equal to zero, so |a| is not equal to zero."

After hearing the answer, Ning Wei glanced at the girl next to him approvingly, and said, "I still don't understand, but I think you understand it quite well. You just found the simplest proof method, so it will be even more difficult for me to test your knowledge." The topic, you are ready, we set the matrix a=..."

In this way, Ning Wei gave sample questions to the girls around her, and then explained them, from simple to difficult, from the dormitory to the entrance of the Institute of Mathematics in just [-] minutes, Jiang Chenshuang really felt that the accompanying matrix problem that had been troubling her seemed unacceptable There is a problem, and by the way, the concepts of inverse matrix and irreversible matrix are also consolidated...

It's a very strange experience. Really, Jiang, who is in love for the first time, doesn't really know if other people's love is the same. He just thinks that if this is love, it seems that it will not delay but will promote learning. No wonder Yanbei University never objected to students falling in love on campus.

When the two arrived at the entrance of the Institute of Mathematics, a black Audi was already parked waiting at the entrance. Ning Wei glanced at the license plate, which was issued to him by his account manager yesterday, and checked the time. It was just 07:30, and he made an appointment with the bank to leave at [-]:[-]. It seems that the driver also arrived earlier. Everyone is on time today.

The driver was a young master who looked to be in his 30s. He was wearing white gloves. When he saw Ning Wei bringing Jiang Chenshuang to the door, he immediately got out of the car and said to Ning Wei, "Mr. Chen Guangming, who has contacted you, is also serving you these days, please get in the car."

"Hello, Master Chen, I've worked hard for you these days." Ning Wei nodded, and then dragged Jiang Chenshuang, who was still dazed, to the back of the car.

"Where is the car?" the girl asked in a low voice.

"I don't know, the services provided by the bank. Don't worry about it, do you understand what I just told you?" Ning Wei explained.

"I seem to understand, but I feel that I need to do more examples to consolidate." Jiang Chenshuang answered honestly.

"Well, if you still have problems with the adjoint matrix, then the problem of linear correlation must be half-knowledgeable. Wait, Master Chen, how long does it take from school to the Forbidden City?"

"Well, if there is no traffic jam, it will take about four to 10 minutes."

"Oh, that's enough time, thank you, Master Chen!"

Ning Wei turned his head when he got the answer, and continued: "Let me tell you, the correlation or irrelevance of vector groups is a very abstract concept. When you see related topics, you have to pay attention to the fact that there is a group with different meanings from that of any ancestor. , the former only requires existence, while the latter requires everything, emphasizing arbitrariness. For example, if I give a condition, there is a vector group α1, α2...αs, and there is always 0α1+0α2+...+0αs=0, then the vector group Whether α1, α2...αs are linearly related, in fact, the question is whether there is another set of k1, k2...ks besides what I just said, so that k1a1+...is established.

"Sounds very simple, right? Let me give you another example. Let a be an n-order matrix and α be an n-dimensional column vector. If a^m-1α is not equal to zero, and a^mα is equal to zero, prove that the vector group α, aα, a^2α, ... are linearly independent."

The topic is really talking about the topic, the only thing that is a little bit too much is that Ning Wei, who is sitting in the car and giving the topic to the girl next to him, is no longer satisfied with holding the little hand, but stretches out his arms to hug the girl when he is giving the topic as a matter of course Waist, of course, he didn’t stop talking, and even the sample questions came at his fingertips. Although the speed of speech was not fast, Jiang Chenshuang had to concentrate to keep up with the rhythm of Ning Wei’s narration. Facts have proved that when people are extremely concentrated, they will really ignore the surrounding situation.

So it wasn't until classmate Jiang started thinking about the sample questions Ning Wei gave, and when he probably got the result and wanted to speak, he suddenly realized that he seemed to have entered Ning Wei's arms. What happened?

But before she could twist her body, Ning Wei continued: "Have you not figured out the proof steps yet? You need to combine those mathematical concepts before to think about the problem."

Student Jiang replied not quite calmly: "I figured it out..."

"I figured it out, what did you mean? If you didn't say it, how would you know you figured it out?"

"Just say that?" Jiang student twisted his body unnaturally.

"Eh? What's wrong? This is not a confidential question, the simplest line generation question, you are afraid that the master driver will know? When you study, you must concentrate, have no distractions, and have the kind of taishan collapse in front of you without changing your face." Do you know that you have a stable mentality? Especially when you are studying mathematics, you may miss a knowledge point because you are distracted, and you may not be able to understand the follow-up questions. You see, you are now studying and thinking about problems. Not concentrating enough, just thinking about messy things, that's not a good thing." Ning Wei educated, tilting his head in pain.

This seemed to make sense, but Jiang Chenshuang couldn't find any reason to protest and object, so he leaned obediently in Ning Wei's arms and said softly: "Oh, just use the definition you mentioned before and ride together, let's assume... ..."

"Well, yes, this idea is completely correct, but it is not the easiest way. In fact, there is another trick. You can directly substitute k2 equal to zero into the formula when you get k1a^m-0α=1, and then you can The conclusion is drawn directly. Next, I will give you a more difficult question..."

Ning Wei spoke very happily, not only because Nephrite was in his arms made him feel proud and excited, but also because he felt that classmate Jiang was so smart that he could almost explain all the knowledge points in one lecture, and of course this also had his function.Ning Wei did not follow the content of the textbook step by step, but based on his understanding, he crushed all the important and difficult points, and then analyzed the context and analysis clearly...

That's when the car was parked in a parking lot very close to the Forbidden City.

For Ning Wei, he really doesn't understand that ordinary cars can't drive here, especially on special days like National Day.Naturally, he didn't know that in order to do this, the bank specially prepared a temporary special pass for the car that he, a vvip customer, had prepared.

After pulling classmate Jiang out of the car generously like this, she was recognized by a middle-aged woman who also just got off the car and probably came to the Forbidden City to play.

"Hey, you are Ning Wei, right? Wow, Ning Wei is the god of learning, my son admires you the most, can I take a photo with you? Is this your girlfriend? Let's take a photo together?"

How should I put it, this is the first time Ning Wei has encountered such a thing as a fan's mother asking for a group photo when traveling.But for this kind of thing, Ning Wei is also experienced. When he was in Jiang University, he encountered many times when he asked for a group photo. When he was in a good mood, he took classmate Jiang and asked the other driver to help him for several times. Zhang Ying, after a friendly farewell, officially started today's journey.

"By the way, I discussed it with Senior Brother Lu yesterday. Senior Brother Lu suggested that my sister should come to our school's middle school to study. What do you think?" In the crisp autumn weather, Ning Wei held his girlfriend's little hand, feeling refreshed asked.

"It would be best if you could come, and you can take care of your younger sister nearby, but didn't you say you were the only child? Is it your cousin or cousin?" Jiang asked.

"My father and mother are the youngest in the family. How can I have cousins? There are actually two cousins. I'm talking about Jiang Chenlu. By the way, isn't your sister my sister? Since you think it's fine, that's fine. Then I will directly ask her what she thinks tonight, and if she agrees, I will find someone to arrange it later. This way you can take care of her nearby." Ning Wei replied as a matter of course.

"Ah? You are talking about Chenlu? No need? And you have to bother others. It is very troublesome to apply for borrowing. Let's not bother others, okay?" Jiang Chenshuang was stunned, and quickly shook Ning Wei's arm Said.
