From Almighty Scholar to Chief Scientist

Chapter 154 19-year-old person in charge of a national key project

"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.

It's like designing a program. A good programmer may be able to handle a program with five lines of code, but a good programmer may not be able to handle it with more than a dozen lines of code, and eventually a bug has to be created.

This Lin Xiao is good in the field of mathematics, but why is he so good in computational materials now?
Seeing these people's astonishment, Cao Zhong couldn't help thinking that when he knew from Chen Bao that Lin Xiao was still engaged in computational materials science, didn't he look like this?

Feeling slightly emotional in his heart, he then said, "You don't need to understand some people with common sense. Lin Xiao belongs to this kind of person."

Hearing what Cao Zhong said, these people nodded immediately, feeling deeply convinced.

……

The funding can be approved, Cao Zhong naturally conveyed the good news to Lin Xiao and Chen Bao directly.

"500 million?" Chen Bao showed a smile on his face: "It should be possible to experiment twice, not bad."

"Hehe, don't worry, 500 million is not enough, let's apply for more."

Cao Zhong showed a smile on his face, and then said to Lin Xiao: "By the way, Lin Xiao, let's add the contact information. I will send you the project application form, and you can fill it out and hand it to me. After that, you will go through a special channel. A Funding will be approved within a week."

Lin Xiao was taken aback: "Should I apply? But I don't know how to design experiments."

"Of course you applied." Cao Zhong shook his head: "This is the material you designed. Of course you are the person in charge of this research group, so the credit belongs to you. Otherwise, those of us who are engaged in calculation materials in China will find someone to help design it. In the experiment, the main credit should be given to others, do you think there are still people who are willing to engage in computational materials science?"

Chen Bao also said with a smile: "If it's yours, you can continue. You just invite me to come to the research group to help you. Moreover, you will become the youngest person in charge of a key research project in our country at the age of 19." Ah, don't you want to try?"

Hearing what the two academicians said, Lin Xiao stopped giving way, and said, "Then please trouble Academician Cao."

……

a week later.

A research group on the design of a new type of titanium alloy production process was secretly established. Today, Lin Xiao, who is only 19 years old, has become the person in charge of this national key project, and the members of the research group are academicians. host.

If such a lineup is spread, it will probably attract countless people's surprise.

An academician actually works under a 19-year-old young man?
However, due to the secret nature of this project, not many people will know about it. Except for the members of the research group, there are no more than ten people who know about this research group for the time being.

For Lin Xiao and the others, they don't need others to know, all they need to do is to do their tasks well, that's all.

In this way, time passed quickly.
