From Almighty Scholar to Chief Scientist

Chen Bao patted Cao Zhong with a smile, and said to Lin Xiao: "Academician Cao and I are old friends, and we are both on our own. He is also the deputy general manager of Aviation Development Group. It is no problem to ask for funds."

Lin Xiao suddenly became pleasantly surprised, "Then thank you Academician Cao!"

"Ham, what's there to thank for this, we are all for our national defense!"

Cao Zhong said with a smile, suddenly he remembered something again, and said, "By the way, Lin Xiao, have you told others about this?"

"Not really." Lin Xiao shook his head.

"That's good." Cao Zhong said to Lin Xiao with a solemn face, "You also know that the situation our country faces internationally is not particularly peaceful, so in order to protect our military secrets, and also to protect yourself, If this material can really achieve this expected result after it is finally prepared, then it will definitely become our secret technology, and there cannot be any disclosure, including your contribution in it, can you understand this?"

Hearing Cao Zhong's serious words, Lin Xiao nodded heavily and said, "I know, I won't say it."

In fact, he had already been prepared for this kind of thing, so he didn't answer when Huang Haoran asked him before. Similarly, he didn't perform simulation calculations on his personal computer, after all, he couldn't guarantee that his computer Security is not safe.

Seeing Lin Xiao nodding, Cao Zhong showed a smile on his face, patted him on the shoulder, and said, "Okay, as long as you can succeed, this credit will definitely be recorded in your file. If the file is decrypted in the future, everyone will not Will forget your contribution to this."

"Well, what I can do for the country is what I should do."

Lin Xiao responded, and at the same time, he also had an inexplicable feeling in his heart. In this way, could he be regarded as joining the ranks of secret guardians?

Just like the shock and touch he felt in his heart after hearing the story of the father of the Huaguo nuclear submarine.

There are also those Long March veterans who kept their names incognito after they were discharged from the army, and their identities were not known until after their death because their relics were dug out.

The current strength of Huaguo has a lot to do with these invisible guardians, and Lin Xiao also feels a sense of honor and honor to be able to join this rank and become comrades with those predecessors.

And his answer also made the two academicians looking at him have some different emotions in their eyes, with relief and emotion.

Finally, Cao Zhong said: "Okay, let's not talk about this for now, Lin Xiao, you can write your results into a report later, and then I will take these reports to a meeting and try my best to obtain resources for the research and development of this material."

"Okay, I'll take it out as soon as possible." Lin Xiao nodded, and then said, "Oh yes, actually, I think that if I use the supercomputer to do the calculation again, it may bring more powerful proof to the theoretical result."

"Extraordinary?"

The two academicians were taken aback.

"If you use supercomputers, you need to design related programs. Can you do this?" Chen Bao said, "Of course, if it doesn't work, I will ask someone to design it for you."

Lin Xiao said, "I can design it myself."

In the past few months of study, due to the needs of computational materials science, he has also made considerable progress in program design, and there is no problem in designing this program.

This is why many people who originally studied computational materials science say that if they do not achieve any results in materials science, they will directly switch to become a code farmer.

Hearing Lin Xiao's words, Chen Bao nodded and said, "Okay, that's it. I'll help you apply for supercomputing later. Our funds can still support the application for supercomputing."

"Thank you."

"Hey, I have already said that there is nothing to be thankful for, let's work hard together." Chen Bao smiled and waved his hands.

"Ok!"

Lin Xiao nodded with a smile on his face.

It is not only for the two academicians to spare no effort to provide help, but also for the achievement of their own goals.

……

Next, according to what Cao Zhong said, the report was produced first.

Of course, since the supercomputer has not been used for the final verification, Lin Xiao can only write down the various previous calculation results for the time being.

As for the applied supercomputer, it is Sunway TaihuLight.

After all, Sunway TaihuLight was developed by the country, and its security and confidentiality are guaranteed. However, since there are many organizations applying for Sunway TaihuLight, they need to wait in line for about two to three weeks.

Although national institutions like them can generally jump in the queue, the Supercomputing Center will naturally not provide them with privileges if they have not declared the importance of this project.

Of course, Lin Xiao was not in a hurry, because he applied for supercomputing for two purposes. The first purpose was to provide stronger evidence for his calculation conclusions, as Cao Zhong and Chen Bao said.Using the more powerful parallel computing power of supercomputers to expand the calculation scale of this new material model, the results obtained are generally more similar than the ordinary computers they used before.

However, this is only the first purpose, and the second purpose is based on Lin Xiao's sensitivity to numbers, combined with his knowledge and previous calculation results, he has a mathematical model for the material given by the system. , aroused some doubts.

There is a certain gap between the various properties of the titanium alloy material given by the truth point and the theoretical properties calculated on the computer.

The actual properties of the titanium-aluminum alloy material given by the system are stronger than the calculation results, such as mechanical strength and some thermodynamic properties, which are much stronger.

After all, he spent so many truth points to make it.

This also means that this new material is fully capable of bearing a higher temperature before the vortex, thereby increasing the thrust of the engine.

However, this is not the most important thing. There is such a large gap between the calculated results and the actual properties, which also means that something has not been discovered.

Lin Xiao had a hunch that it was probably because there was a certain mechanism or physical properties that had not been discovered.

And he wants to use his mathematical ability to deduce this mechanism, and then use supercomputing to verify it!

And this is also a major role of computing materials, that is to use mathematics to explain some unexplainable things in some experiments!

Chapter 153 19-year-old person in charge of national key projects

"The atomic radii of zirconium, niobium, and molybdenum are larger than that of aluminum, so this will lead to distortion of the lattice and increase in the volume of the unit cell."

"Also, relative to the atomic mass, aluminum is only between one-third and one-fourth of those atoms."

"If you compare the axial ratio..."

"The closer the axial ratio is to 1, the more isotropic the crystal, the weaker the covalent bonds between atoms, and the stronger the metallic bonds, which will affect the ductility of the final material."

Lin Xiao recalled various theories and wrote some data on manuscript paper.

Because there is data exchanged from truth points in his mind, Lin Xiao seems to have guidance. If his calculation conclusion can match this result, it means that the theory is correct.

And now, he is building such a theory.

However, this is still somewhat difficult.

Because the answer provided by the truth point is a standard answer without a process, just like when doing a math problem, when you encounter a question you don’t know, you want to copy the standard answer later, but you find that the standard answer has only one answer, and the process is omitted.

So how to derive the final answer is the most critical.

For ordinary people, facing such an answer, it may be completely impossible to connect the existing data with it.

But for Lin Xiao, the occasional flash of inspiration when looking at these numbers may allow him to find his way.

"If you start from the method of quantum chemistry... first try the molecular orbital method."

Then, Lin Xiao began to try.

Although metals are composed of atoms, the formation of chemical bonds can still be solved by the molecular orbital method.

Here it is necessary to use the solution of the Schrödinger equation to describe the wave function of the electronic motion state.

In this way, Lin Xiao used more and more draft paper, but it also made him addicted to it.

Entering the field of mathematics is like returning home. These mathematical symbols are all so cute and comfortable to write. I really like studying mathematics.

cough cough.

All in all, Lin Xiao now needs to find an unknown that can reflect the gap between the calculation result and the actual result.

Time passes quickly.

These days, Lin Xiao didn't come to the Institute of Aeronautical Materials anymore, but stayed in his room all the time, constantly building the theories he needed.

However, due to Cao Zhong's request, he sorted out the report in advance and handed it over to Cao Zhong.

Even if there is no supercomputer, Lin Xiao's calculation results on those software are generally enough to apply for funding.

So Cao Zhong planned to try it out first, and if he could get the funding as soon as possible, of course it would be best to get the funding as soon as possible.

A few days later, a meeting was held among the top management of the Aviation Development Group.

The people who attended this meeting were all senior executives of the Aviation Development Group, besides Cao Zhong, there were also the general manager of the Aviation Development Group, and several other academicians.

"Old Cao, what are you going to do with this meeting?"

Cao Zhong didn't answer, but said first: "Let's talk about it later, let's all sign a non-disclosure agreement first."

Seeing Cao Zhong being so solemn, everyone present were stunned.

"Confidentiality agreement? What is so important?"

"Old Cao, have you made any major breakthroughs?"

Hearing the "major breakthrough", the eyes of these people also lit up. As a group specializing in the research and development of aero engines, they have signed many non-disclosure agreements, large and small. Of course, they can guess what is the situation that needs to be signed. protocol.

Cao Zhong was expressionless and kept his mouth shut, and said, "Don't ask first, rules, sign first."

Soon, nondisclosure agreements were sent to the people present one by one, and the people present signed the nondisclosure agreements directly without talking nonsense.

"Is it okay to say it now?"

Until the confidentiality agreement was accepted, an academician asked again.

Cao Zhong still didn't say anything, but put away the non-disclosure agreement first, read it roughly, and then looked at the doors and windows, in case there were ears in the partition, and then sent out the printed reports one by one from the file bag .

The people present had been waiting anxiously, and when they got the report, they were shocked.

"Titanium-aluminum alloy? Can it be used on turbo blades? This mechanical strength...is this true?"

An academician was shocked, "As long as this material is real, the thrust of our engine can be increased by several points at least! Moreover, the density of titanium-aluminum alloy is low, and the thrust-to-weight ratio of the engine that exceeds that of the American F22 will not be a problem! "

The academician's surname is Liu, and his name is Liu Xiangkong. He has a very high status in the domestic aviation field, and his qualifications in their Aviation Development Group can also be said to be the highest. He was so surprised, of course, because the nature of this material really surprised him. Feel incredible.

And the others also looked surprised.

But at this moment, someone discovered the problem and said, "No! This material was calculated and simulated? Then Lao Cao, are you kidding us? Can the calculation and simulation be taken seriously?"

Hearing this sentence, the others came to their senses, and looking back, it was indeed the result of calculation and simulation.

They all looked at Cao Zhong immediately, wanting to see what he would say later.

Cao Zhong smiled and said, "If this is true, can I invite only a few of you to come over for a meeting?"

If the material entity had already been produced and verified, then he would not have held a meeting here, but directly wrote an internal reference.

Hearing what Cao Zhong said, the others looked at each other in blank dismay: "Then what do you mean?"

"I think we should allocate funds specifically for the design of the production process of this material, and then set up a research team to develop it. At least, it must be 500 million?"

Cao Zhong looked at Li Yong, the general manager of the group, "Mr. Li, you have to approve this matter."

Li Yong shook his head and said, "500 million is not enough, your results are not convincing."

Although as the general manager, Li Yong is mainly responsible for administrative affairs, but he certainly understands these professional matters, and the main right to approve the group's funds is in his hands, so of course he can't just approve it.

Cao Zhong smiled slightly, without any nonsense, and then took out a series of data reports, which were the results simulated by various software used by Lin Xiao before, and then handed them over to these people to read.

These result data are more and more comprehensive, from molecular dynamics to lattice dynamics, from phonon spectrum to phonon sub-wave density diagram, etc., each of these conclusions shows this The material has excellent performance.

The academicians and experts who originally thought that Cao Zhong came here to make them happy were all speechless at this moment.

At the same time, they were all the same as when Cao Zhong saw Lin Xiao's calculation results before, and they began to think, what if it really succeeds?

"This..." Li Yong opened his mouth and said after a while, "500 million...is that enough?"

Hearing what Li Yong said, Cao Zhong showed a smile on his face: "If it's not enough by then, then it's fine."

If you have a chance to succeed, why don't you approve it?

And the previous Academician Liu Xiangkong even stood up directly: "Approval, it must be approved! In the past, the country's hundreds of millions and billions of dollars may not be able to make a splash, but now there is a chance of success with a few million. No approval? If you don’t have money, go to the National Council to ask for it!”

Seeing that the people with the highest qualifications had spoken, Li Yong naturally couldn't stop him, "Okay, Academician Cao, you go and submit the project application. Let's use a special channel, and the money will arrive within a week."

However, when it came to this, they suddenly realized, who made this calculation result?Who will the task force consist of?

Li Yong asked this question: "Academician Cao, who is applying for this project? It can't be you, can it?"

Because he signed the confidentiality agreement, Cao Zhong said with a smile: "Lin Xiao, do you know?"

"Lin Xiao?"

Everyone present was stunned. Is there such a talented person in the domestic computing materials industry?

However, at this time, someone thought of it: "Hey, I learned from Academician Chen Bao that Lin Xiao, who proved Goldbach's conjecture, seems to be in his research group? Old Cao, what you don't know is Him?"

"Yes, it's him."

Cao Zhong smiled and nodded.

Hearing Cao Zhong's confirmation, these academicians and experts were once again shocked.

"This... how is this possible? Isn't he a mathematics student? How can he still have such a deep research on computational materials?"

If you want to calculate this kind of result through computational materials science, you don't just need to input data blindly and just adjust various parameters. This not only requires sufficient knowledge reserve, but also is very important for the application of this knowledge.
