From University Lecturer to Chief Academician

On the same day, Cao Dongming took Wang Hao to visit the Institute of Aeronautical Materials, talked about the report, and reminded him not to talk about the research done by Peng Hui's team, also for the sake of confidentiality.

Even the Institute of Aeronautical Materials cannot talk about the projects that have just entered the national major secrecy. It depends on the follow-up evaluation of the project and the opening of data.

They came back to the problem of reporting.

Wang Hao has already prepared for this. He is going to talk about the methods used in the data analysis process and the calculation methods that were finally researched.

The final calculation method is the classic place, and summed up together, you can write a top data mining paper, which is naturally not a small achievement.

This kind of achievement is relatively high in practicability, especially for the research on titanium alloy materials, and generally will not be published.

Now being able to make a small report at the Institute of Aeronautical Materials is to let more people know about my research, and to make a small contribution to the development of the national materials field.

Cao Dongming attached great importance to Wang Hao, and he scheduled the report at nine o'clock the next morning, which can be said to be the 'golden time' during working hours.

At the same time, in order to make the report more 'lively', he specially sent messages in several chat groups of the Institute of Materials, and talked to several material calculation experts in the Institute of Materials.

it is a pity.

Cao Dongming didn't seem to have that much face.

The next day Wang Hao came to the Institute of Aeronautical Materials and entered the small conference room where the report was to be made ahead of time, only to find that there were only a dozen people sitting there.

He thought he came too early, so he asked Cao Dongming specifically, and seeing Cao Dongming's embarrassed expression, he already knew the answer in his heart.

"Okay, just a dozen or so people."

"Not too many!"

"After all, everyone is a top expert."

Wang Hao comforted himself. He didn't really care too much. After all, he was invited to give a report for Cao Dongming's sake. After the report, he could leave.

As for how many people come to listen, it doesn't matter much at all.

He still wants to open it.

After entering, I shook hands with everyone and got to know each other. I also felt that the School of Materials Science and Technology still paid attention to it, because there was an academician who was also the vice president of the School of Materials Science and Technology.

That's Qu Shigang.

Qu Shi is just over 50 years old, and he is the youngest academician of the Academy of Aeronautical Materials. He was originally a Ph.D. in the direction of computational materials. Promoted to the director of the aluminum-magnesium alloy research laboratory.

Later, he entered the field of composite materials and achieved considerable results.

At the end of last year, Qu Shi had just led the team to complete a major project of composite materials, and now he has been relatively free since the beginning of the year, and is also preparing for a new project.

When I saw Cao Dongming sending a message inviting people to listen to the lecture on data mining, I came here with curiosity.

In fact, his curiosity was reversed.

Recently, Qu Shigang has been relatively free. He has no projects in hand and can only be responsible for some materials institute affairs. He often goes to read the news.

Then he noticed Wang Hao.

For a while, a lot of media were reporting on Wang Hao, as well as the "unavoidable story" between him and Donggang University. Later, it became a self-examination by Donggang University, and it turned out that the alloy laboratory incident had nothing to do with Wang Hao.

Qu Shigang also paid careful attention to the investigation announcement issued by Donggang University, and the responsibility rests with another core researcher in the laboratory.

"Typical problems, find the people below to take responsibility!" Qu Shi was filled with emotion as soon as he saw the announcement, and he also noticed the sentence "Professor Wang Hao doesn't understand material research".

At first, Qu Shigang didn't care at all, and just read the news after reading it.

But his memory is very good.

When Cao Dongming said that Wang Hao was invited to give a report, he asked specifically and knew that it was indeed Wang Hao from Xihai University.

As soon as Qu Shi looked through the report again, he felt that Cao Dongming was very unreliable. He invited a young mathematics professor who didn't understand materials to come to the Institute of Materials to give a report on data mining in the field of materials?

Even if this young mathematics professor has completed a lot of top mathematics research in half a year, the data mining in the field of mathematical theory and materials is fundamentally two different directions. There is also a correlation, but the correlation is very, very low .

So the form just came.

He did come with curiosity, but this curiosity is 'reverse'.

...

Wang Hao didn't know that the 'Academician Qu' in the audience came to listen to the report with reverse curiosity.

Although there are only a dozen or so people in the meeting room, one of them is an academician who is also the vice president of the Materials Academy, and the rest are also researchers and professors, and there is at least an associate researcher level. Although the number is small, they are all elites. I feel a little relieved in my heart.

Then he started reporting.

Wang Hao's opening remarks are very interesting. He said, "I am also very nervous standing here. To be honest, I don't understand aviation materials. I am a complete layman. I just have some research on data mining."

"In the next explanation, if there are any problems, everyone must remind me."

After telling the truth, he started his own report, first explaining from conventional analysis methods.

There are several conventional methods for data mining in the field of materials, including detailed analysis of experimental data, arranging charts, doing probability research on digital distribution, and so on.

These are also conventional means of data mining and are used in most analytical work in related fields.

Wang Hao's explanation is relatively more in-depth. He gave a few very direct examples, including the data of the titanium alloy manufacturing process, and listed them out for analysis, which is easy to understand.

"The Gift of Teaching" increased the understanding of others by 40%, which also played a big role.

Everyone who listened to the lecture felt that after listening to Wang Hao's explanation, they seemed to have a deeper understanding of the method used countless times.

Immediately, they became more serious.

Qu Shigang couldn't help secretly praising, "The level is indeed a bit. These conventional analysis methods are explained like textbooks."

Cao Dongming is sitting next to Qu Shigang. He is not interested in data mining and analysis at all, because he is not doing research in this direction.

Now it's just to make up the numbers.

However, he has great confidence in Wang Hao, or in other words, everyone who knows Peng Hui's team project will have great confidence in Wang Hao.

The achievements of Peng Hui's team can no longer be described as luck.

The research on the compressive strength of β-type titanium alloy may be able to produce a material with a tensile strength exceeding 1500 MPa by luck, but it is simply impossible to manufacture a material with a tensile strength above 1600 MPa.

Not to mention, the level of more than 1700 MPa, that kind of probability is much smaller than winning a lottery of 100 million.

Therefore, just like what Peng Hui said, or what they saw with their own eyes, Wang Hao played a vital role in the conclusions drawn from the analysis of experimental data.

It can be judged from this that Wang Hao must be the top expert in the relevant field.

Cao Dongming felt normal when he found that everyone in the conference room was listening very seriously, including Academician Qu Shigang, who was getting more and more involved.

That's a top expert in data mining. Can the explanation he made be attractive?

In terms of conventional analysis methods, Wang Hao spent half an hour explaining, and then entered a critical stage, he began to explain a brand-new calculation and analysis method, "This method is a combination of the previous methods, and also a combination of A brand-new method can maximize the elimination of data interference and expand differences."

"The most basic of them uses a discrete mathematics approach."

"Let's see..."

As the explanation gradually deepened, the people in the meeting room listened more seriously, because they found the content much more difficult, and it was not easy to keep up with the rhythm and understand.

At this time, Wang Hao's professionalism was also shown. He was explaining mathematics in a leisurely manner, deriving calculations step by step, and using the final conclusions, and then transforming them into a calculation method.

"This calculation method can magnify the difference in data. Even if there is only a small difference, it will definitely become obvious through calculation."

"Afterwards, we can analyze by drawing..."

When entering the drawing analysis step, it is even more difficult to keep up with the understanding.

Among them, when it comes to the content of advanced function theory, more than half of the people can't keep up because they don't have the relevant theoretical basis.

But even if they couldn't keep up, they still listened carefully, because they found that the method Wang Hao explained was indeed very subtle, and it was very suitable for use in the experimental analysis of alloy materials.

This method may not be effective in other data mining fields, but it is very helpful for the research of alloy materials.

Later, Wang Hao spent another half an hour finishing, and he tried his best to explain in more detail.

But in fact, the effect is small.

If you have enough basic knowledge, it is not a big problem to understand the content, but there are a bunch of material calculation experts sitting in the audience. It is not so easy for them to understand some advanced discrete mathematics and function theory.

However, many people are not in a hurry if they don't understand, because the report will have detailed records, they just need to get the records and do research slowly.

End of report.

The people in the meeting room were much more enthusiastic than at the beginning.

Qu Shi had just completely changed his view of Wang Hao, and he secretly scolded Donggang University many times in his heart, "Why don't you understand material research? At this level, you still don't understand material research?"

"It looks like a data mining expert in the field of alloy material research and development, definitely at the top expert level!"

Qu Shigang also asked a question that he didn't understand.

Wang Hao also explained it patiently. In fact, the problem with Qu Shigang is the lack of foundation. He doesn't quite understand the analysis of advanced discrete mathematics. If you don't understand advanced mathematics, you can't understand the problem, so you don't continue to ask questions.

The same goes for everyone else.

At this time, Cao Dongming asked, "Professor Wang Hao, you gave several examples for the research and development of titanium alloys, so can the latter calculation method be directly used in the analysis of experimental data in the research and development process of titanium alloy materials?" superior."

"It depends."

Wang Hao replied, "Some situations are acceptable, and some situations are not. If you understand all the content and compare the specific research content, you can analyze which ones can be used."

He shook his head, "There are too many fields involved in this area, and I can't explain them one by one. Let me give you a simple example."

"For example, in terms of smelting temperature control, it is not enough to let the metal melt. Sometimes, at an appropriate temperature, the strength of the alloy produced may be higher."

"Look at this example..."

Wang Hao began to explain patiently again, and the explanation lasted for more than ten minutes.

Everyone in the audience listened very carefully. When Wang Hao gave examples, they understood the method better.

At least in the content of melting temperature control, it is known that relevant methods can be used for analysis.

After Wang Hao finished explaining, someone stood up and asked, "Professor Wang Hao, can you talk about the cooling and tempering process..."

"this……"

Wang Hao hesitated immediately.

It's not that he didn't want to say it, but he didn't complete the "General Method for Data Analysis of Beta Titanium Alloy Experiment".

[Inspiration value: 86. 】

The data can already explain everything. He can already explain some processes directly, but he still needs to study some processes carefully.

Wang Hao looked at the time and said with some regret, "When I came yesterday, Cao Dongming told me about the general analysis method of titanium alloy experimental data. I just thought about it roughly and did not complete the research, so in the There are many processes, and I can’t explain them one by one.”

"It is important for everyone to understand this analysis method, which is also the main content of my report here."

After Wang Hao finished speaking, he stepped off the stage.

There was also applause in the conference room, but everyone was very awkward. They felt like they were reading a novel. They had just seen the climax and were looking forward to the next content...

The author is too-supervised!

Stop writing!

It was a feeling of being so depressed that I was about to suffocate to death!

Not to mention other people, Qu Shigang has this feeling.

What Wang Hao just talked about is the core content, that is, how to apply the analysis method he has developed in the data analysis of which process.

It is important to know the method, and it is even more important to know where the method can be used.

result?

Stop talking!

Qu Shigang had the urge to vomit blood, but Wang Hao had already said that he hadn't finished the research, so he couldn't ask the other party what to say.

Next, Cao Dongming entertained Wang Hao to the cafeteria of the material institute for a meal.

Checking the time, Wang Hao left.

His plane ticket was at after three o'clock in the afternoon, so he went back to the hotel to pack up and was about to go to the airport to catch his flight.
