Into Unscientific Chapter 520

  Chapter 520 He is not enough

  Looking at the few pieces of calculation paper that Lao Guo pushed in front of him.

  In Xu Yun's tired eyes, a fleeting and inexplicable look flashed across his eyes.

  If we say that the previous communication in English is the first wave of 'exploration'.

  Then these few questions now should be the second round of tests.

  The former test identity.

  The latter assesses ability.

  After all, even graduates from the same university in the same period may have a sequence of abilities, some are strong and some are weak.

  The two identities of a top student and a scumbag do not only exist in later generations.

  If Xu Yun is just a graduate of the Department of Mathematics at Cambridge University

   Then his value is like that.

  Think here.

  Xu Yun took a deep breath and turned his head to look at these pieces of calculation paper.

   "∫Ωτ(ut2+a2ux2)dx≤et0"

   "∫Ω0(ψ2+a2φx2)dx+Kτf2dxdt]"

   After a while.

   Xu Yun breathed a sigh of relief.

   It's okay, it's a very simple question, as long as you have hands.

  So he raised his head slowly, and said to Lao Guo in a tone that sounded like speculation but was actually firm:

   "Comrade Guo, this should be a partial differential equation?"

  Old Guo nodded, the expression on his face did not change much:

   "That's right, Comrade Han Li, can you see the specific issues discussed in the equation?"

  Xu Yun heard the words and observed the paper counting again, and said slowly:

   "If I'm not mistaken, this should be the energy inequality of the one-dimensional initial value problem?"

   Hear Xu Yun's answer.

  Old Guo squeezed the fingers of the paper counting paper, and immediately exerted some force.

  He really understands it!

   Well known.

  The so-called equation refers to an equation that contains unknown quantities.

   For example, there are algebraic equations, functional equations, etc.

   If the equation consists of the independent variable, the unknown function, and the derivative or differential of the function, then it is a differential equation.

  A differential equation with only one independent variable is an ordinary differential equation, or ODE.

   A differential equation with multiple independent variables is a partial differential equation, or PDE.

  So for an international student in the Department of Mathematics.

   Judging that this is a partial differential equation purely through the form of the formula, it can only be said that it conforms to his basic "personality", which can be regarded as basic literacy.

  But judging from the content of the equation that it is calculating the initial value problem requires strong academic ability.

   After all, the hyperbolic equation is considered a problem with high barriers in this period, because the wave equation it covers is directly related to many frontier research.

   It is no exaggeration to say.

  Many universities these days refuse to teach relevant mathematics knowledge to overseas Chinese students.

   Seeing Xu Yun give such a precise answer, Lao Guo suddenly became interested, and asked Xu Yun again:

   "Comrade Han Li, if you were asked to do this question, what would you start with?"

   As a result, I just finished speaking.

  Old Guo realized that this question was a bit too much, and quickly added with a dry smile:

   "Of course, think about it if you can. If you can't think of it for a while, don't force it. After all, your injury is not healed yet."

  He didn't know Xu Yun's specific major before, so it was naturally impossible to prepare the corresponding "assessment materials" before coming.

  The few manuscript papers in his hand are actually calculation papers in a non-core project that he carries with him, and the problems involved have not been resolved yet.

   Therefore, the question he raised has a strong element of curiosity, and strictly speaking, it is a bit difficult.

   "The idea of ​​solving the problem."

  The result surprised Lao Guo.

  Xu Yun hesitated for a moment, then gave an answer:

  "If I were to solve the problem, I would multiply ut on both sides of the wave equation and integrate on Kτ, deform the left side of the equation and apply Green's formula."

   "Then analyze the positive and negative of the integral terms along the boundary of Kτ and make scaling, and finally use Gronwall's inequality, and there should be a relevant solution"

   "Integral over K, Green's formula?"

  Old Guo blinked, subconsciously began to think about the feasibility of Xu Yun's plan.

   As one of the earliest science masters in China, although Lao Guo is not as good as Hua Luogeng and Chen Jingrun in mathematics, his mental arithmetic ability should not be underestimated.

   After clarifying Xu Yun's thoughts.

  His pupils shrank suddenly.

  This idea seems to

   Is it really feasible?

   More critically.

  The energy method can also prove the uniqueness of the solution in nature, which is the consensus of the wave equation.

   That is to say, the result must be the only solution!

  Think here.

  Old Guo couldn't help turning his head and glanced at Cai Shaohui who was beside him.

   Right now.

   In the hearts of the old and the young, Qiqi had an impulse:

  Go back to the project team and immediately deduce this problem!

  If the idea given by Xu Yun is correct

  The project team can save at least five days of computing time!

   And just when Lao Guo was excited, Lin Yu's voice sounded in his ear again:

   "Guo Gong, it's almost time, look."

  Lao Guo came back to his senses and turned to look at the clock opposite the hospital bed.

as expected.

   At this time, the time has come to 11:30 in the morning, and it has been 20 minutes since they entered the ward.

  See this scenario.

  Although Lao Guo still had many questions in his heart and wanted to communicate with Xu Yun, he had no choice but to stand up and said to Xu Yun:

   "Comrade Han Li, you are recovering from a serious illness, and your body has not fully recovered. You need to recuperate."

   "So we won't bother you for now, you can just rest in peace and recuperate, and I will definitely visit again after a while."

  Xu Yun also nodded upon seeing this:

   "Comrade Guo, goodbye."

   After Lao Guo and others left.

  The nurse rolled down the back of the hospital bed, re-hung a bottle of injection for Xu Yun, and gave him some medicine.

A few minutes later.

  Xu Yunping lay on the bed, and while he still had some energy, he began to think about the problem.

   Currently relying on the broken version of the Cambridge diploma presented by Halo, his identity can be regarded as barely fooled.

   Also if he expected it well.

  He also gave a passable answer to the 'assessment' of the mathematical calculation paper just now, and the first show has been pulled to the fullest.

   According to the historical situation he knows.

  No matter which of the above points, at most it can only make his start relatively calm.

   As for relying on this little "talent" to alert the leadership and enter the core layer of the base, that is pure daydream.

   In other words.

  If he wants to gain the trust of the organization, he must produce one or more big news.

   as large as

   Enough for the leadership to ignore their "origin".

   But the problem is that I can't even move now, how can I break the situation?

  With this doubt.

  Xu Yun's eyelids became heavier and heavier, and he finally fell asleep slowly.

   And just when Xu Yun fell into a deep sleep again.

  Old Guo took Cai Shaohui and Zhou Cai away from the staff hospital and came to the base headquarters only a few hundred meters away from the hospital.

   After inspection and registration.

  The three of them soon arrived outside the office of Li Jue, the general manager of Factory 221.

   "Old Li!"

  Seeing that Li Jue's office was only half-covered, Lao Guo left Cai Shaohui and Zhou Cai outside, pushed the door open and broke in:

   "Good news, good news!"

  At this time, Li Jue was watering flowers on the window sill with a small kettle. Hearing this, he couldn't help but stop, and asked with a smile:

   "Good news? Why, Lao Guo, could it be that the research on the reflection of weak shock waves has achieved results?"

   "Weak shock wave? Thank you for daring to think!"

  Old Guo grinned and waved his hands twice, walked to the desk, picked up a big tea bowl, raised his head and took a big sip, and wiped the corner of his mouth when he was done:

   "The project that tmd just launched yesterday, you came up with the results today - it took Laomei more than 80 days to break through."

   "You want to see the result today, okay, go out and turn right into the factory director's dormitory, everything in your dream!"

  Seeing this, Li Jue couldn't help laughing twice.

  As the general manager of the base, he is naturally aware of what Lao Guo said. That project has not yet been written off.

   Asking Lao Guo about the so-called weak shock wave results is purely to suppress Lao Guo's arrogance.

   Then he strolled to the table with the kettle in his hand, glanced at Lao Guo, and said to him:

   "Okay, just kidding, let your stinky mouth say good news. It seems that the wounded comrade is doing well?"

  Lao Guo came to the general office to look for Li Jue once before, and also wanted to leave Zhou Cai, Li Jue's assistant, so Li Jue naturally knew what Lao Guo did just now.

   Right now, Lao Guo can come back so refreshed.

It is clear.

   That wounded man must have shown some value.

as expected.

  After Li Jue mentioned the word wounded.

  Old Guo nodded heavily, and even snapped his fingers happily:

   "That's right, the diploma is not stolen, 100% of the international students of Cambridge University - with an authentic London accent, more standard than many comrades say, at least lived abroad for more than ten years."

   "As for the family background, it is similar to what we expected before. The family went abroad early, and after the founding of the country, they hesitated to return to the country, so they sent him back to the country to find their roots."

   "As a result, I met robbers on the road and my property was robbed. After wandering for a while, I had to steal the tiles—he didn't say anything about the last paragraph, but according to what he said, that's basically what happened."

   "Oh, by the way, he claimed to be called Han Li, but Xiao Zhou told me that there is no such person in the files we found, so it must be a pseudonym."

  Li Jue didn't make a sound after Lao Guo started to explain. After listening quietly, his face looked thoughtful.

   At this time, more than ten days have passed since Xu Yun was rescued from the Wayao Factory.

  After Zhou Cai collected the files of overseas Chinese students at Cambridge University, Li Jue also discussed Xu Yun's "composition" with Lao Guo.

   Looking at it now.

  Whether it's Li Jue's judgment, Xu Yun's own statement, or various realistic evidences, it is basically certain that Xu Yun's statement is not wrong—at least in general.

   Then Li Jue put the kettle on the table, fiddled with the lid of the enamel cup twice, and asked Lao Guo:

   "Old Guo, just being a foreign student shouldn't make you so happy, even if you can speak English well."

   "Let's talk, is his physical condition recovering more ideally, or his professional level is very high?"

   "Okay, Lao Li, you can turn your head fast enough."

  Old Guo looked at Li Jue in surprise, shook his head and said:

   "The body is recovering enough. Although Director Lin is trying his best to stuff him with donkey hair, he is still not completely out of danger."

   Li Jue let out a cry:

   "So his professional level is very high?"

  Old Guo nodded, considering that Li Jue is not a professional, he blurred the specific concept:

   "That's right, very high to be precise."

   "Graduated from the Department of Mathematics of Cambridge University, he saw the content of the manuscript I gave him as soon as he recovered from his illness, and also gave him a very feasible solution."

   As he spoke, he paused and added:

   "From this matter alone, there are no more than ten people in the base who have this kind of thinking ability. Of course, this kind of thing has a lot of chance, and there is definitely no way to compare it in this way."

   Li Jue glanced at Lao Guo.

  Although he is not a professional scientific researcher, he is a professional in trying to understand human psychology.

   He was silent for a moment, and asked Lao Guo thoughtfully:

   "Old Guo, you mean to add him to the watch list?"

  Old Guo nodded, glanced outside the house, and said in a low voice:

   "That's right, Lao Li, judging from the conversation process, I personally feel that his attitude towards me should be kind, and awareness can also be cultivated."

   As a result, the words were not finished.

   Li Jue interrupted him:

   "Not enough, Lao Guo."

  The second half of Lao Guo's speech was interrupted.

   After a while.

   Li Jue sighed, poured Lao Guo a glass of water, and explained:

   "Old Guo, you should know the organizational regulations and procedures. It is impossible for us to absorb such a person who has no footsteps into the system immediately."

   "At least what you said alone is really not enough."

  Old Guo opened his mouth when he heard the words, as if he still wanted to rescue him:

   "But Lao Li, Han Li's situation is different, he is leaving now"

   "I know he can't leave the base now, Lao Guo!"

   Lao Guo still spoke halfway, but was interrupted by Li Jue:

   "I also know that even if he is really an enemy agent, he cannot pass the information under the current circumstances."

   "I know that our multi-round re-inspection system will not give him the opportunity to destroy the calculation results, but Lao Guo"

   "Rules are rules. Our mission is too special and important. Any unstable factors are absolutely not allowed."

  "He misunderstood the policy and used a pseudonym, that's okay! It's okay to sneak back to China! Let us treat his injuries for free, it's still okay! But"

   Said here.

   Li Jue put his hand on his friend and colleague, and said word by word:

   "If you want him to enter our project, absolutely not."

   "Old Guo, this project of ours is about the entire country, and about whether hundreds of millions of compatriots will crawl on their knees or walk on their feet in the future. We must maintain absolute rationality that is irrational or even illogical."

   "Perhaps he is a talent for you, Lao Guo, and has given you some surprises, but from my perspective as the factory manager, he is far from enough."

  Looking at Li Jue who speaks earnestly and earnestly, Lao Guo is silent.

   After a while.

  He nodded slightly:

   "Old Li, I was the one who was abrupt."

   Li Jue's chest relaxed slightly when he saw this. What he feared most was that Lao Guo would be tough and confront him to the end because of his "cherishing talents".

   Then he opened his mouth, ready to speak, but heard Lao Guo say:

   "Then Lao Li, if you ask him to calculate some data without revealing the real situation, it shouldn't be a problem?"

  Li Jue was slightly taken aback, then nodded after recovering:

   "Of course, pure data calculation, the current base is really short of manpower - isn't this one of the purposes of our rescue him back?"

  "The watch list and core items are not discussed, and ordinary data can be touched by him."

  The expression on Lao Guo's face softened a little.

   But soon.

  Once again, an unstoppable thought popped up in Lao Guo's mind:

   "Speaking of Lao Li, is it really impossible for him to enter the watch list?"

  Li Jue glanced at him, and said firmly:

   "Unless he has confessed all the information of the three generations of his ancestors and verified it clearly, there is no need to even think about it!"

  Old Guo still does not give up:

   "What if his contribution is big enough?"

   "Contribution is big? It is impossible to make a big contribution."

  Li Jue snorted coldly, then suddenly thought of something, and pointed out the window:

   "Let's put it this way, Lao Guo."

   "If he can enter the watch list without revealing his true situation, I will go and chew the ax your teacher gave you on the spot!"

Note:

  Grandma's situation suddenly became a little bit bad. It wasn't as serious as being admitted to the ICU, but she was admitted to an emergency, and the indicators were not very optimistic. Today is a bit short, and I will ask for leave tomorrow, sorry.
