Chapter 23
Ji Zhixing wasn't quite sure what level the first-year math students had reached, so after thinking for a moment, he asked, "Have you learned Bernoulli's numbers yet?"
"Uh... I've learned something." What are Bernoulli numbers?
Ji Zhixing invited Zhu Bo to sit next to him, saying it would be easier to explain the topic that way.
Zhu Bo turned his phone upside down on the table to prevent Ji Zhixing from seeing the live stream screen.
Ji Zhixing circled the formula in the problem and began to analyze it.
"You see, due to the uniqueness of Laurent series, and the definition of Bernoulli number..."
Zhu Bo's heart sank. He had entered the workforce right after graduating from high school, so naturally he wouldn't understand. But seeing Ji Zhixing's eloquent and skillful explanation, regardless of whether what he said was correct or not, at least it sounded plausible.
Zhu Bo is currently unable to view the comments, but he can still guess what the comments section will be like.
Ji Zhixing's face is already a huge advantage; if he also exudes a bit of erudition, he'll definitely attract a lot of brainless women to his side. With so many people on his side, it won't be so easy for his partner to manage the comments section.
However, the female viewers in the comments section were not as brainless as he claimed.
"I'm a physics major, and so far Ji Zhixing's analysis of the problem is correct, but I don't know if he can actually solve it after the analysis."
"I haven't studied physics, but if you just focus on the logic of what he says, it still sounds reasonable."
"Judging from this, he does have some talent; he's not just a pretty face with no substance."
"This question should be very basic. After all, he's a physics major, so it's normal for him to be able to understand it, right?"
"I'm a physics student, and this question is actually a very basic question for first-year university students. It's about the same level of difficulty as a quadratic equation for a high school student."
"Which school is the person upstairs from? This question could be used for a postgraduate entrance exam."
"Asking such a difficult question to a sophomore is a bit unfair of you, Little Pig."
"The course arrangements are different for each school. Guangling University is a 985 university, so this level of difficulty should be manageable."
"It's impossible to learn Bernoulli numbers in freshman year. How can you understand such difficult problems if you haven't learned Bernoulli numbers?"
Just because you think it's difficult doesn't mean others think it's difficult too.
...
While the comments section was still debating the difficulty of the question, Ji Zhixing had already finished analyzing it.
"Do you understand the question?"
"Huh? Oh, I understand." Zhu Bo nodded vaguely.
Ji Zhixing then began to analyze the problem-solving approach.
"Next, we need to find a recurrence relation for Bernoulli numbers that is easy to calculate. First, we construct M(z,n)=（∞）∑（k=0）……=（1-e^zn）/（e^-z-1）
On the other hand, Bernoulli numbers can be obtained by slightly changing their form;
(∞)∑(n=0)·B(n)/n! (-x)^n-1=1/(e^-x)-1……
So……
Therefore, there is...
Taking n=1 in the above formula, we get...
From this, we can calculate the first few terms of the expansion;
1/e^z-1=1/z-1/2+z/12-z^3/720+z^5/30240+Ο（z^6）"
Looking at the lines of formulas and numbers on the draft paper, Zhu Bo regretted not having asked a physics major to watch the live stream beforehand so he could find any mistakes.
Before I knew it, Ji Zhixing had finished explaining the solution.
"Does that make sense now?"
"Hmm, more or less."
Zhu Bo wanted to find fault with him, but what could he do if he couldn't understand it? But it didn't matter, he had made many preparations. Passing this hurdle didn't mean Ji Zhixing had won.
He took out another piece of draft paper from the book's pages: "Could you take another look at this problem for me?"
Ji Zhixing took it and looked at it; the question was:
In quantum field theory, the propagation amplitude of a scalar field is defined as D(xy) = ∫d^3p/(2π)^3·2E(p)...
Where p is the three-component momentum in classical mechanics, and E(p) satisfies the relation… Prove that the above propagation amplitude on the surrounding channel C(F) is equivalent to…
Ji Zhixing sensed something was wrong and asked a few questions about the question. Sure enough, the boy couldn't understand the question at all.
Moreover, he felt that when he explained the first question, the boy didn't seem to have really understood it.
Why is he so fixated on a topic he can't understand or comprehend?
Zhu Bo saw the doubt on Ji Zhixing's face, and his heart skipped a beat. He quickly tried to cover up his mistake: "Senior, I know I'm not very smart. I just want to make up for my lack of talent by starting early and working hard."
"Ah, that's good." Ji Zhixing thought to himself, he couldn't dampen his junior's enthusiasm for learning.
After thinking for a moment, he picked up his pen and began to explain the problem.
"In the integral measure, d^4p = dp(0)d^3p. Therefore, first remove m... then separate out the parts that do not need simplification... use the residue theorem to calculate the bounded integral... and thus we have..."
While Ji Zhixing was explaining the problem at length, the viewers watching the live stream were also making their own comments.
"I think Ji Zhixing is quite capable; he's already done it, hasn't he?"
"Yes, and they didn't think about it for long either. Even if they're not top students, they're definitely not bad students either."
"When will this young man debut? I can't wait!"
"I've had enough of all those low-level entertainers in the entertainment industry. Let's have a breath of fresh air!"
"Don't you think he's too superficial? Why can't he just focus on his studies? Why does he have to jump into the entertainment industry, this big dye vat?"
"Ultimately, it's all about money. If everyone goes to school with this goal in mind, what future does our country have?"
"It's just a personal choice, why does it have to be elevated to this level? Is it really necessary?"
"It's absurd that top students can't make big money in the entertainment industry while underachievers can."
...
While the comments section was debating Ji Zhixing's career choices, Ji Zhixing had already finished answering the second question.
"Did you understand?"
"Hmm...more or less." He actually wanted to point out a few flaws, but alas...
But don't worry, he has a plan!
"Little Pig," Zhu Bo's partner whispered into the Bluetooth headset, "We can't keep asking those ordinary questions. Seven or eight out of ten people in the comments section are supporting Ji Zhixing now, and I've already been scolded several times!"
Actually, being criticized isn't the problem. He's in charge of guiding the comments, and sometimes he even deliberately makes some idiotic remarks to incite conflict, so being criticized is the norm.
However, the current sentiment in the comments section is very unfavorable to them. Although most viewers don't understand the physics questions, they also can't tell whether Ji Zhixing explained them correctly or not, including him.
In short, everyone assumed that Ji Zhixing truly knew the material because he spoke so smoothly without any stumbles.
Moreover, the viewers in the live stream are there to debunk myths, not to learn a physics lesson. Many of their regular fans are getting impatient because they didn't see what they were expecting, and the number of viewers watching online is steadily declining.
Two or three out of ten comments are criticizing the slow pace, while seven or eight out of ten are siding with Ji Zhixing—and this is only after he used several alternate accounts to influence the narrative.
"Little Pig, bring out that question!"
Zhu Bo hesitated, wondering if this would negatively impact the show's effect.
This question wasn't originally in the plan; he copied it from his cousin's computer.
When he went to his uncle's house, his uncle told his cousin to go out and buy some wine. Having nothing else to do, he glanced at his cousin's computer. His cousin worked at Hengtai Technology, apparently in charge of some digital seismic wave laboratory software system; of course, he couldn't understand the research he was doing. But when he saw the words "NS equations," something struck him. It was mentioned on the Guangling University forum that Ji Zhixing was currently researching this.
When my cousin came back, he deliberately tried to get information out of me and learned that the document on the computer was about a problem their lab had recently encountered. He didn't understand the specifics of the problem, but he knew it was a summary of difficult problems related to the "NS equation".
While my cousin was washing the dishes, he casually copied a document, intending to use it to fool the fans in the live stream and make it seem like they had put a lot of effort into the pre-production of their show. He didn't really think it would be of any use.
However, they couldn't figure out Ji Zhixing's true level. If Ji Zhixing answered their third and fourth questions, their episode would be ruined.
And this was the only question they were certain Ji Zhixing couldn't possibly answer.
It is said that there are 5 PhDs and 1 postdoctoral fellow in Hengtai Technology's digital seismic wave laboratory. If such a team cannot figure out the problem, how can Ji Zhixing, a sophomore, possibly outperform PhDs and postdoctoral fellows, even if he is a top student?
However, precisely because the problem was so difficult, even if Ji Zhixing couldn't solve it, they still couldn't achieve the desired effect.
"It's okay. How many people watching the live stream can understand how difficult it really is? I'll Photoshop this problem onto a first-year physics textbook later, and then guide the comments to say that the problem is actually very simple."
Some commenters have already begun to question the righteousness of their targeting of Ji Zhixing.
Of all professions, only studying is noble. Although this saying is outdated, people always tend to be more tolerant and protective of those who excel in their studies.
If they can't turn the tide, not only will this episode be ruined, but their live stream's reputation will also be severely affected.
Zhu Bo is also worried about this. Maintaining a show with millions of fans and hundreds of thousands of views per episode is not an easy task.
They had suffered a Waterloo before.
Last year, one of their shows featured a retired female celebrity who was being exposed for deception. Although she had been out of the spotlight for a long time, a TV series she starred in when she was younger was very popular, and young people today can still remember her role, so there was still some value in exposing her. The female celebrity had always presented herself as a philanthropist, but they discovered that she had been hiring children from orphanages to string beads for her husband's handicraft factory.
After the program aired, it generated a great deal of social reaction, but their live broadcast room was met with overwhelming criticism. People said that because of their program, the handicraft factory was shut down, and the orphans who could have supported themselves were forced to return to the predicament of relying on others for help.
They donated a lot of money and supplies to the orphanage and even did several days of live-streamed volunteer work there, barely managing to salvage their live-streaming reputation. If they fail again this time, their past mistakes will surely be dug up and retaliated against. Who knows what price they'll have to pay to get away with it then?
After weighing the pros and cons, Zhu Bo no longer hesitated. He pretended to be troubled and looked at Ji Zhixing:
"Senior, may I ask you one last question?"
"Sure, go ahead and ask."
Whether you understand it or not, a desire to learn is always a good thing.
He had consulted Professor Yan several times before, and Professor Yan always explained things patiently. Sometimes, if he felt he hadn't explained things clearly enough, Professor Yan would send him long supplementary explanations afterward to help him understand more thoroughly.
Ji Zhixing has always respected Professor Yan, and when faced with a junior student who is eager to learn, he feels that he should also be more patient.
Besides, explaining another problem will only take a dozen minutes at most. He still has an hour before lunch, and with the afternoon, he can almost finish writing the "background technology" part, which is not slow progress.
However, after seeing Zhu Bo take out a stack of papers from his bag, Ji Zhixing realized that he probably wouldn't be able to write his thesis that morning.
"Junior, your..." The title is way too long.
"Please, senior! I actually saw this in a book. I've been doing a lot of extra reading outside of class to broaden my knowledge. I've been thinking about this problem day and night. If you can solve it, I'll treat you to dinner, okay?"
"No need for that." Since things had come to this point, Ji Zhixing had no choice but to accept the stack of papers.
However, when he saw the words "NS equation", he felt a little conflicted. The question his junior asked seemed too far off-topic.
The Navier-Stokes equations involve many physics concepts such as field theory, Euler's method, body derivatives, and continuity equations in fluid dynamics, which are far beyond the curriculum for first-year math students. Especially since he had just discovered that his junior hadn't even mastered basic concepts like series summation and complex trigonometric functions, yet he was already grappling with the Navier-Stokes equations. Even if he was a late bloomer, this was taking a huge leap forward.
Ji Zhixing hesitated, wondering whether he should advise his junior to take things one step at a time and build a solid foundation.
Hmm... I'm not comfortable with you being so familiar with you, so I'll pass.
Ji Zhixing didn't say anything more, but opened the stack of papers and looked at them carefully.
Indeed, no problem related to the Navier-Stokes equations is easy.
However, he has recently been studying the applications of the Navier-Stokes equations because of the competition, and he even asked the system to print out the relevant papers on the application of the Navier-Stokes equations in recent years. Although he has not finished reading them all, he has read about 70 or 80 percent of them.
Furthermore, when I consulted Professor Yan, he would sometimes unconsciously start to extend the discussion further, starting with the steady incompressible Navier-Stokes equations and then expanding to the Navier-Stokes equations for multi-segment airfoils.
Therefore, it can be said that Ji Zhixing has considerable expertise in the application of Navier-Stokes equations. Although he has not yet made any innovations, he is already quite proficient in analysis and application.
After reading the beginning, Ji Zhixing roughly understood that this was a simulation calculation of a laminar fluid process. In that case, the initial conditions, environmental conditions, and boundary conditions of the laminar fluid must be fully considered. Perhaps by simplifying it into segments or regions, analytical general formulas for different cases can be obtained...
As Zhu Bo predicted, questions have begun to emerge in the comments section regarding this question.
"No matter what, you shouldn't ask a second-year student about the Navier-Stokes equations, right?"
"I feel like the streamer was deliberately making things difficult for us."
"I did a quick search online, and this is the Millennium Prize puzzle with a $1 million reward! What's the point of asking Ji Zhixing this kind of question? Isn't it perfectly normal that he can't solve it?"
"That's not the case. The Millennium Prize Problem is about proving the existence and smoothness of the Navier-Stokes equations. This problem only involves the application of the Navier-Stokes equations."
"For a sophomore, the Navier-Stokes equations are completely beyond the scope of the curriculum."
"Perhaps the curriculum varies from school to school. At my school, we have this kind of theory in the first year. (Image) (Image)"
"From which book were the pictures upstairs taken? They look a little different from the ones I have. (Pictures) (Pictures)"
"This is a textbook compiled by our school; it's not available on the market. (Image)"
"Your self-compiled textbooks are quite outrageous, teaching this level of difficulty to freshmen."
"Guangling University is a 985 university after all, so the courses in the Department of Physics should be quite difficult."
"So, this question isn't actually that difficult?"
"But the title is way too long! So many pages."
"You think this is a high school math problem? This is normal in college."
"Could you please tell me which school the person upstairs belongs to?"
"You're being strange. Why do you keep asking me which school I go to?"
"Don't say anything, upstairs. This person might be from Ji Zhixing's agency and could be trying to cause trouble at your school."
"Just because what I said is detrimental to Ji Zhixing's image as a top student? Please! I was just stating the facts! I'm scared."
"This agency has gone too far!"
"What nonsense! I'm just an ordinary student, how did I become someone from a talent agency?!"
"Stop making excuses. You've been speaking up for Ji Zhixing from beginning to end."
"That's because I'm a normal person who can think for myself!"
So you're saying everyone's brainless?
...
Seeing the comments section erupt into chaos, with everyone no longer focusing on the difficulty of the question, Zhu Bo's partner breathed a sigh of relief and continued to use several alternate accounts to stir up trouble with sarcastic remarks.
While Ji Zhixing was focused on the question, Zhu Bo lifted the cover off his phone on the table, glanced at the comments section from the side, and breathed a sigh of relief. This was a sure thing!
After relaxing, he was bored and began to scrutinize Ji Zhixing.
Damn pretty boy, if he had looks like that, he wouldn't need to go through all the trouble of debunking fakes. He could just sit there and chat and receive countless tips from rich women.
Thinking about the hardships and exhaustion he endured while making the show, Zhu Bo felt increasingly indignant. It was only because of his face that Ji Zhixing was noticed by a talent agency.
He worked as a streamer on a live streaming platform, relying entirely on himself from start to finish. Ji Zhixing, on the other hand, didn't have to do anything; his agency took care of everything. With such meticulous preparation even before his debut, his treatment after debut is sure to be even more extraordinary.
At that time, Ji Zhixing can easily earn tens of millions from a single advertisement, while he himself works himself to the bone to secure sponsorships, earning at most 200,000 for a single sponsored post. And he can't advertise too frequently or too obviously, otherwise his fans will complain. But for celebrities! The more advertisements they have, the happier their fans are.
This world is so damn unfair!
Seeing Ji Zhixing's clothes and shoes, Zhu Bo felt a surge of emotions. This outfit alone must have cost nearly ten thousand yuan, and judging from the candid photos of Ji Zhixing, this was his usual level of clothing.
Damn it! What gives him the right? He's just a poor student, yet he's so extravagant! I have to make sure he doesn't overdo it later; a student dressing so luxuriously will have a negative influence on the values of teenagers!
Zhu Bo was racking his brains, devising ways to subtly guide Ji Zhixing into saying things that would make people hate him.
Ji Zhixing's mind was also racing. He read very quickly and was very focused, quickly finishing dozens of pages of questions.
He was genuinely curious about what kind of books would include such titles; it was quite interesting. He would definitely remember to ask his junior for the book list later.
After reading the question, Ji Zhixing began to think.
As Professor Shiing-Shen Chern, the father of differential geometry, once said, mathematics is like cooking; only by doing a lot can you become proficient and innovate.
Since the learning system was introduced, Ji Zhixing has not wasted a single day. Even when busy with competition projects, he makes sure to complete at least one "creativity" task every day.
The questions the system posed could only be described as tricky and bizarre.
For example, yesterday's question was to prove that 1 + 2 + 3 + 4 + 5 + 6 ... (the cumulative number is infinite) = -1/12!
Every number on the left side of the equation is greater than 1. Shouldn't the sum of these infinitely large numbers be positive infinity? How could it possibly be a number less than 1, and even a negative number!
However, Ji Zhixing still managed to prove it in the end, and the process was surprisingly simple! Although he proved it himself, he still felt terrible, as if his previous understanding had been overturned.
Moreover, the system specifically selected this relatively easy question from the level 2 question bank for him because it saw how busy he was with the competition.
But such leniency doesn't happen every day; it's only once a week. Most of the other problems require Ji Zhixing to pull out several strands of hair to solve.
By doing practice problems and racking his brains every day, Ji Zhixing's thinking ability has been greatly developed and improved.
If we're using cooking as an analogy, he'd be good enough to be a head chef at a five-star hotel. He could also open a private restaurant, the kind where diners aren't allowed to order, the chef can cook whatever he wants, and customers would flock to it.
Therefore, Ji Zhixing treated these dozens of pages as simple problems, without thinking too much about them, and began to analyze them part by part according to his own problem-solving habits.
First, several assumptions must be made about the fluid. The first is that the fluid is continuous. This emphasizes that it does not contain voids that form its interior, and it does not contain the aggregation of mist-like particles. Another necessary assumption is that all the fields involved are differentiable, such as pressure, velocity, density, temperature, etc.
Because of Ji Zhixing and Zhu Bo's prolonged silence, the comment section became desolate after another argument.
"This episode was so boring, it was too long."
"I came here to relax, why am I here to watch people do math problems? I'm so tired of it!"
"Knock me when you get the results, I'm logging off now."
"Let's go have lunch first, this handsome guy is good enough to make the meal more enjoyable—"
"Do women only care about looks? Can't they pay attention to something more meaningful?"
"Food and sex are human nature, and the people are happy to see them. Who do you think you are?"
"I remember you. In the last episode, a beautiful woman walked by in the anchor's shot, and you even said something about her being very voluptuous. Oh, so that's what you call meaningful focus!"
"Exactly, it's incredibly lewd. People were just passing by, and their eyes were glued to them."
...
Seeing the comments section buzzing again, Zhu Bo's partner finally stopped typing. This episode was exhausting. Ji Zhixing didn't know how long he would have to think about this question before giving up; he couldn't let it drag on like this, prolonging the show's dull moments. He decided that if Ji Zhixing hadn't made a move in another hour, he would call Zhu Bo to leave the library, and they could just jump to a conclusion. Although it might be a bit anticlimactic, at least they'd finished this episode of "Pretending to be a Genius."
Amidst the chaotic comment section, a brand new, blank account suddenly appeared.
"Excuse me, where did this question come from?"
Nobody paid him any attention.
He persisted with asking the question several more times before someone finally replied.
"It seems the anchor saw it in a book."
"Which book is it? Could you tell me?"
"You'd have to ask the streamer."
"Okay, thank you."
After typing those words, Shi Yanshi left a private message for the streamer. However, he knew the streamer wouldn't reply so quickly, so he continued watching the live stream.
Shi Yanshi was in the lab correcting data discrepancies when he heard from his lab technicians that their lab data had been leaked and was being used as a gimmick by a livestreamer, so he rushed over to check it out.
To be honest, he felt relieved when he saw the information, but after seeing the anchor's face flash by, he became furious.
He initially thought it was his competitor's doing, but it turned out to be his cousin's doing. Recalling his cousin's sneaky behavior at his house that day, what else could he not understand?
Fortunately, this document did not contain their lab's core data, otherwise he would have been in serious trouble.
Shi Yanshi had never been familiar with or interested in the content of Zhu Bo's live streams, but now, because of the stolen information, he had no choice but to watch the live stream to see what Zhu Bo was up to.
He clicked on the program introduction, skimmed through it, and felt extremely disapproving of Zhu Bo's actions. Without any substantial evidence, Zhu Bo forcibly assumed that Ji Zhixing was faking his academic genius persona to prepare for his debut.
The three reasons listed in the program description are simply far-fetched, mostly based on subjective conjecture and judgment.
For example, does a handsome guy necessarily have to be discovered by an entertainment company? Their lab has a lab technician who was the campus heartthrob for twelve years, and now he lives a secluded life in the lab doing research.
Therefore, he felt some sympathy for the young man who looked like a student in the center of the camera, especially when he was racking his brains over the thing that had been giving them a headache for a month.
This material describes a problem they recently encountered while designing digital seismic wave prediction software. They created a model to simulate changes in electron density above the ground before an earthquake, but the more complex the model, the higher the simulation distortion, and the greater the difference between experimental data and actual tests.
They concluded that the main problem lay in the handling and application of the Navier-Stokes equations, but they couldn't pinpoint exactly where the problem was.
After a month of aimless work, a group of physics PhDs realized that specialization is key, and mathematical problems should be left to mathematicians. They posted job openings last week and commissioned a well-known headhunter to find suitable mathematical talent for their lab, but haven't found a suitable candidate yet.
Hopefully it will be soon. Shi Yanshi sighed as he watched their experiment stall for a month.
His mind was always filled with theories and data; he couldn't appreciate the lively discussion in the comments section. After watching the almost static live stream for an hour, his patience wore thin. Just as he was about to call a lab technician to monitor the stream, the screen moved.
After running through all the ideas in his mind, Ji Zhixing turned back to the first page of the document.
His mind was now in a state of heightened excitement, just like every time he solved those strange and unusual problems given by the system.
This question is indeed very complicated, but also very interesting.
The incompressibility of laminar fluids inherently deviates subtly from reality, stemming from various theoretical assumptions and simplifications. This means that mathematical models based on the Navier-Stokes equations cannot perfectly represent reality. Therefore, solving analytical solutions to the Navier-Stokes equations requires close attention to the physical meaning of each variable and parameter; otherwise, the solution deviates from physical reality and leads to significant deviations in the fit.
In other words, the key lies in the multi-region superposition and application of the Navier-Stokes equations. In fact, as a physics student, he should have found the application of the Navier-Stokes equations quite challenging.
However, his experience designing a zero-gravity seat from scratch gave him a considerable understanding and application of the Navier-Stokes equations. Therefore, once the hidden problem was identified, untangling this mess wasn't too difficult.
Ji Zhixing turned to a new page of the draft paper and said, "First, let's introduce a flow vector function to define the global properties of the fluid element and the deformation properties of the fluid..."
Shi Yanshi sat in front of the computer, his expression gradually becoming serious.
"When designing the SP model in the environmental quality model, the numerical solution method of the finite element method can be used for piecewise calculations..."
Shi Yanshi slammed his hand on the table. "That's right, as long as there are enough segments and they're detailed enough!"
He picked up the internal phone to call his colleagues to watch the live broadcast, but worried about missing the details of the subsequent explanations, so he suppressed his eagerness and continued listening.
"At least one set of dynamic equations concerning the overall properties of the flow should be introduced here..."
Ji Zhixing then used numerical methods to perform piecewise calculations, writing more than a dozen draft papers.
"Alright, that's it for this step, the problem is solved."
Ji Zhixing looked at the draft paper with satisfaction, then glanced at his junior and noticed that he had a constipated expression on his face, as if he wanted to say something but couldn't.
"Where did you not understand?" Ji Zhixing asked.
Zhu Bo remained silent, conflicted; he hadn't understood a thing. He'd started to panic while Ji Zhixing was explaining the problem at length—this was his last resort!
Is it possible that Ji Zhixing figured out a solution to something that five PhDs and one postdoc couldn't solve in a month?! He reasonably suspected that Ji Zhixing had tested him with the first two questions to see that he didn't actually know much, so he made up a bunch of nonsense for this incredibly complex question in order to save face.
Even if his guess was correct, how should he break out of the current situation? Zhu Bo once again regretted not having asked a physics professional to assist him beforehand. He tried his best to find fault, but couldn't come up with anything specific.
Seeing that he remained silent, Ji Zhixing tore off the dozen or so draft papers and handed them to him.
"You can take it back and take a closer look."
Looking at the dozen or so sheets of paper handed over, Zhu Bo realized that Ji Zhixing was quite confident about the matter.
Having ended up being the one being slapped in the face by Ji Zhixing instead of the one being slapped in the face by Ji Zhixing, Zhu Bo didn't even know how he left the library. At this moment, all he wanted was to quickly find a relatively secluded place and say something to salvage the situation.
My partner's anxious voice came through the earphones:
"Little Pig, hurry up and think of something! The comments section has completely turned against us!" Ninety-nine percent of the comments are now on Ji Zhixing's side, and the remaining 0.1% are basically just annoyed by his good looks. If they don't come up with something soon, this episode is a complete disaster!
Zhu Bo's heart leaped into his throat. No! He couldn't let the show end so humiliatingly!
After leaving the library, he wandered around aimlessly until he finally found a secluded corner where no one passed by. He turned on the live stream and glanced at the comments section. Sure enough, people were either supporting Ji Zhixing or criticizing him.
Zhu Bo quickly spoke up: "Hello everyone, I'm Little Pig. From the footage just now, we can see that Ji Zhixing is very eloquent and good at using rhetoric to cover up difficulties he can't solve."
"What the hell? I don't hear anything that Ji Zhixing can't solve."
"The host is trying too hard to save face."
"This episode was a complete disaster."
"I thought he deserved more respect when he admitted his mistake, but I never expected him to still be making excuses now!"
...
"As everyone knows, Xiao Zhu started working right after graduating from high school, so his educational level isn't high. He also greatly envies people like Ji Zhixing who can study and live a carefree life at university..."
The partner understood Zhu Bo's intention in playing the victim and quickly switched to a secondary account to deal damage and support:
"The streamer is already out there earning a living so early. Sigh, the difference in people's circumstances is just too great." "Yeah, some people have to rely on themselves their whole lives, while others are born lucky, blessed with good looks and everything they need."
Upon seeing these two comments, Zhu Bo mentally gave his partner a thumbs up and continued:
"When Ji Zhixing was explaining those three questions, I (Xiao Zhu) actually sensed something was off, but because of my limited education, I couldn't offer any particularly insightful comments. Out of responsibility to the program, I didn't dare to speak up. Later, we will invite physics experts to analyze and explain the points that Ji Zhixing deliberately avoided and misinterpreted in his explanations..."
Upon hearing this, Shi Yanshi couldn't hold back any longer. He cast several "spaceships" to pin his comment to the top.
"I am Shi Yanshi from Hengtai Technology, a PhD in Physics. Below is my □ and degree certificate (picture). I do not think there is anything wrong with Ji Zhixing's solution. In fact, I find it very inspiring."
And Zhu Bo, you stole my lab's research data for a public live stream without permission. I will have my lawyer contact you.
His partner tried to salvage the situation by saying that the person wasn't verified, but Zhu Bo recognized his cousin and panicked, quickly ending the live stream.
Seeing his junior leave in a hurry, Ji Zhixing didn't think much of it, ate lunch at the cafeteria, and went back to the library to continue working on his thesis. However, that very evening, he learned about the live stream.
The three of them in the dorm were all so busy that none of them had time to pay attention to the internet. It was Zhang Biao who saw someone mention this on the school forum and came to tell him.
Ji Zhixing then realized where his strange feeling from that morning came from. He followed the website to Zhu Bo's live stream, only to find that today's episode had been deleted by the host himself.
Is he backing down already? Surely not, just because he solved all three questions?
Ji Zhixing had thought there would be a war of words, but now that there was no need to waste time, he didn't plan to delve any further, since working on his thesis was the priority.
He had just closed the live stream when he received a message on his phone. He opened it and saw that it was from Professor Yan.
“I’ve already contacted the security department and added that streamer to the school’s facial recognition system blacklist. Focus on your studies. If you’re interested in the Navier-Stokes equations, I have a few books on the subject here. Come and get them when you have time.”
Ji Zhixing felt a surge of emotion upon reading it. Professor Yan was a very old-fashioned and serious person, showing no interest in live streaming or anything like that; he must have heard it from one of his graduate students. He read the message several times; it felt so good to be protected!
...
Hengtai Technology Digital Seismic Wave Laboratory.
"It's a success! It's a success!"
A burst of enthusiastic cheers startled Shi Yanshi, who was taking a nap in the lab. He shook his head, and his muddled mind cleared up a little.
What succeeded?
Could it be?!
Shi Yanshi quickly took out his glasses and put them on. Before he could rush to the computer, his colleague Shi Yan grabbed him.
"We succeeded! The experimental data matched the real records with a 99.8% success rate!" Shi Yan was so excited that his voice cracked.
"Really?!" Shi Yanshi was overjoyed instantly.
Yesterday, he hurriedly called his colleagues to watch the live stream replay together. Everyone felt that Ji Zhixing's idea was feasible, so they started to debug it. Half a month later, it was time to verify it. He had been watching it for 48 hours straight and couldn't take it anymore, so he dozed off for a while on a recliner. He didn't expect to receive such good news when he woke up!
Shi Yanshi and Shi Yan stood together in front of the computer, watching the printer output the records page by page. The red experimental data curve and the green historical records matched perfectly, with a deviation rate of only 0.2%, which could almost be called a miracle!
Each time the printer printed a page, Shi Yanshi and his colleagues would check it. Until the printer stopped working, their software did not show a deviation of more than 0.2%.
“So,” Shi Yanshi murmured, “this means…”
No one responded, as if afraid of shattering their fragile dream; at this moment, no one dared to utter a word about the goal they so desperately longed for.
Everyone silently sprang into action, downloading real-time satellite observation data from all over the country, extracting the data they needed, and then inputting it into the software in groups, city by city.
Everyone in the lab remained silent, and the software ran silently as well.
Shi Yanshi felt conflicted. The software hadn't issued any alerts, which was certainly the best outcome. But did nothing really happen? Or was the software's operation not actually accurate?
The tests have covered more than half of the 600+ cities in China. The software used to analyze a set of data in one minute, but now over five hours have passed. Everyone in the lab has been staring at their computers, their initial excitement at the successful experiment gradually fading, replaced by an atmosphere of uncertainty.
Did they really succeed? The software validated the past, but...
Suddenly, a piercing alarm blared, and everyone's hearts jumped into their throats.
A note from the author:
Note 1: The problem and solution here are from the internet; the formulas are omitted.
Note 2: To avoid being accused of padding the word count, I've included the proof here for everyone to see. Although the equation is rather odd, the process is actually quite simple.
Prove that 1 + 2 + 3 + 4 + 5 + 6 ... (the cumulative number is infinite) = -1/12;
Let X = 1 + 2 + 3 + 4 + 5 + 6...
Let Y = 1 - 2 + 3 - 4 + 5 - 6...
XY;
= (1+2+3+4+5+6...)-(1-2+3-4+5-6...)
= [1-1] + [2-(-2)] + [3-3] + [4-(-4)] + [5-5] + [6-(-6)] ...
=0+4+0+8+0+12……
=4+8+12……
=4*(1+2+3+……)
=4*X;
The above equations can be summarized as follows:
XY = 4X;
4X - X = -Y;
3X = -Y;
X = -1/3Y (Important note: at this point, you only need to find the value of Y to determine the value of X.)
Next, take out another Y = 1 - 2 + 3 - 4 + 5 - 6... and add the two sets of Y in a staggered manner;
Y = 1 - 2 + 3 - 4 + 5 - 6 ...
Y = 1 - 2 + 3 - 4 + 5 - 6 ...
Y+Y=1+[-2+1]+[3+(-2)]+[-4+3]+[5+(-4)]+[-6+5]……
2Y=1+(-1)+1+(-1)+1+(-1)……
2Y = 1 - 1 + 1 - 1 + 1 - 1...
Add 2Y again with the positions shifted;
2Y = 1 - 1 + 1 - 1 + 1 - 1...
2Y = 1 - 1 + 1 - 1 + 1 - 1...
4Y=1+[-1+1]+[1+(-1)]+[-1+1]+[1+(-1)]+[-1+1]……
4Y = 1 + 0 + 0 + 0 + 0 + 0...
Y = 1/4 (Important note: Y has already been calculated).
Summarize:
X = -1/3Y;
Y = 1/4;
so;
X = -1/12;
That is, 1+2+3+4+5+6……=-1/12!
Note 3: The two assumptions regarding the fluid here refer to "Aerodynamics and ANSYS Fundamentals".
