From University Lecturer to Chief Academician

dark night.

American, California, south of the San Francisco Bay Area, Stanford University.

The lights on the second floor of an office building were still on.

The gray-haired Professor Brian Dweck stared at the computer screen energetically.

He looked up at the time, it was already past ten o'clock in the evening, he continued to look at the screen nonchalantly, and continued to record and calculate with a pen.

He is reviewing papers.

As the co-review editor of "Computer Mathematics and Information Engineering", Brian Dweck is very conscientious, and he also likes the paper review work, because he can always see some novel developments and ideas in it.

like now.

"Fourier transform assists in the construction of data models and algorithms for data analysis?"

"One application paper, two algorithm architecture papers?"

"Three submissions..."

When Dweck saw the manuscripts sent by the editorial department, he felt absurd. It was not just about the content of the papers, but because there were too many papers.

One author, three paper submissions!

After carefully reading the content of the three papers, he realized why the other party submitted three papers. One of them was about the algorithm application of Fourier transform, which can be understood as "expanding thinking and explaining algorithm application".

The other two are purely algorithm-based analysis methods for constructing data models, which are real research in the field of Fourier transform application computer algorithms.

The three papers are completed together, and the contents of them are related.

"The algorithm paper is divided into two parts...it should be too many pages."

Dweck took a general look and knew why the following papers were divided into two.

For ordinary paper submissions, it is difficult to pass the review if it is more than ten pages.

Those who publish dozens of pages of papers in one breath, all report the results first, and after confirming that the results are true, effective, and very meaningful, they may be invited by the corresponding journals to contribute and publish them all.

The content of the two algorithm papers in front of me has been streamlined and streamlined, reaching twenty-two pages.

After Dweck reviewed the narrative paper on the application direction, he immediately became interested. He found that the author of the paper was very thoughtful, and some of the application directions in it had never been thought of. enforceability.

Then, he looked at algorithm papers.

Paper submission is not to write all the content, even if it is a computer algorithm paper, it only explains the main body of the algorithm and makes an introduction along the direction.

The main content of the paper submitted by Wang Hao is to apply Fourier transform to the construction of mathematical models, and the method of assisting data analysis under the framework of mathematical models.

Even if only the general framework is introduced, the main content is very complicated and not so easy to understand.

Dweck watched carefully, studied carefully, and continued to follow the calculations with a pen. After studying for three hours, he finally understood the process of constructing the mathematical model.

He made a cup of coffee, took a short break, and then returned to the screen, sighing, "What a genius!"

"This algorithm can be applied to data analysis."

"For the analysis of ultra-large-scale data, the more data there is, the more efficient this method will be..."

Dweck took a break, then read on.

It took more than an hour to finish reading the rest of a paper, and then looked up at the time, and found that it was already early in the morning, so I didn't continue to read, but sent a message to the editorial department, "These three papers are very meaningful .”

"It is recommended to be published together as the core of the current issue."

He made a comment by the way, "Genius idea! Genius creativity and research!"

"It is a brand-new application method of Fourier transform, which is very valuable for ultra-large-scale data analysis. In the future, it may even change the framework mode of high-end data analysis—"

at the same time.

Wang Hao was staying in the small library on the top floor of the laboratory building of the Faculty of Science.

This small library is only open to doctors or teachers, and it contains some very professional and esoteric books.

Many books do not even have translations, and are purchased directly from abroad, because ordinary people simply cannot understand them, there is no market, and translations are meaningless.

Wang Hao found a full English version of "Analysis of the Mathematical Principles of Differential Equations", and sat in a chair to read it carefully. It took more than two hours to read it.

He found that the analysis of the basics of mathematics was very in-depth and thorough.

Reading books can increase knowledge and also increase inspiration.

This book made Wang Hao feel that he had gained a lot, and at the same time, the task of "solving the generality of specific partial differential equations" also increased the inspiration value by two points.

Two o'clock is already a lot.

Partial differential equations involve a wide range of knowledge, and his research is also very difficult. It is necessary to demonstrate the existence and uniqueness of sigma_k, Q-curvature equations, curvature flow, and Monge-Ampere type equations involved in geometry. , regularity and asymptotic behavior...

etc.

Every bit of increase in inspiration is very valuable.

Wang Hao is not alone in the library.

Zhou Qingyuan was also there.

There are two other people I don't know. It seems that a doctoral supervisor brought a doctoral student to choose books. Their voices are not loud, but because the library is small, some voices still reach the ears.

"Constant variable method."

"Inhomogeneous ordinary differential equations."

"annotation."

Wang Hao captured a few key words, which should be related to the content of the doctoral thesis, which is related to the "constant variation method linking non-homogeneous ordinary differential equations".

This mathematics topic is not difficult and is suitable as a topic for a doctoral thesis.

The two are discussing.

The doctoral supervisor suddenly said, "Professor Zhou is here. He is an expert in differential equations. If you have any questions, you can ask Professor Zhou."

Zhou Qingyuan smiled and raised his head, "You can also ask Wang Hao, he is no worse than me in differential equations."

Although it was an affirmation of Wang Hao, it was obviously a modest statement.

"This is Professor Huang Pei."

After he finished speaking, he gave Wang Hao an introduction.

Wang Hao called out politely, "Professor Huang."

"Wang Hao!"

Huang Pei smiled and nodded to Wang Hao, then looked at the doctoral students under him, "This is Xiao Sun, Sun Jian."

Sun Jian smiled shyly, and looked at Wang Hao a few more times. Leaving Zhou Qingyuan as an old professor, he knew that Wang Hao's "mistake in scientific research" was on the news.

In addition, Wang Hao is indeed very young, much younger than him.

Sun Jian still said, "I just don't understand the general solution of the inhomogeneous ordinary differential equation and the Riccati equation."

"It's a bit convoluted..."

He said scratching his head.

Zhou Qingyuan nodded and said a few words, "Ricati's equation, there should be no problem in solving the Riccati's equation, right?"

"The Riccati equation is connected with the non-homogeneous ordinary differential equation. The difficulty lies in the transformation and transformation..."

"There is a classic Riccati equation that can be solved iteratively..."

Zhou Qingyuan said a few words briefly, and then asked Wang Hao, "Do you have any research on the Riccati equation and non-homogeneous ordinary differential equations?"

All three looked at Wang Hao.

"Non-homogeneous equations..."

Wang Hao has the direction of inspiration of "solution of one-dimensional non-homogeneous equations". It needs to be merged and converted normally."

"Our studies are generally special cases, or those complex..."

He only planned to say a few words, but found that 'inspirations' kept popping up in his mind.

Then just keep talking.

"Complicated Riccati equations are also very complicated to solve, and non-homogeneous equations require some other tools and other means..."

"For example, ode45, to do numerical solutions in numerical analysis, you can use the fourth-order and fifth-order Runge-Kutta algorithm..."

"Using algorithms and superimposing some conventional solutions to inhomogeneous equations, you can..."

Wang Hao said a lot in a row.

During the discussion, ideas kept popping up in his mind, and he continued to talk after a while. He even found that he was about to complete a research on the "solution of special calculations of the Riccati equation".

The three people in the room listened very carefully, and looked at them differently.

Sun Jian looked over with admiration. He didn't expect Wang Hao to be able to talk eloquently about the solution and connection of specific equations in front of the two professors.

Moreover, the thinking is clear.

Some of the content has definitely been carefully considered, and can be described as 'research', rather than knowledge that can be seen in books.

Zhou Qingyuan found that sometimes Wang Hao just happened to say what was in his heart, and sometimes the content of what he said was different, but equally meaningful.

To put it bluntly——

What he thought of, Wang Hao also thought of; what he didn't think of, Wang Hao still thought of.

"Could it be that Wang Hao has surpassed me in understanding differential equations?"

Zhou Qingyuan was very surprised.

He has always known that Wang Hao is excellent, but even a genius needs to grow.

Engaged in mathematics research for nearly 30 years, thought he was already a top mathematician, but was surpassed by a doctor who just graduated in his early twenties?

Huang Pei and Zhou Qingyuan felt very similar.

Whenever he thinks of something, Wang Hao can easily say it, and Wang Hao can also say other things that he didn't think of.

Huang Pei's face was filled with shock, "This Wang Hao is amazing!"

"No wonder!"

"Even if there are scientific research mistakes that have brought huge losses to the project, Professor Zhou still strongly recommends that the school sign Wang Hao!"

"I see!"

"He's only in his early twenties, he'll be great in the future!"

Finally changed the state, it was not easy.

The new book has published 30,000 words, and I will ask for everything from now on~~Thank you for your support!
