From University Lecturer to Chief Academician

The academic report speech of the Hanghu Abayun R\u0026D Center is scheduled for the day after tomorrow night, and the schedule for two days and one night is still very tight.

This is also Wang Hao's request.

He just wanted to come back and continue to do research after finishing his work. The B-level difficulty of "Partial Differential Equation" has almost hundreds of inspiration points.

Wang Hao's goal was to "make up a hundred" before leaving, but the result was not satisfactory.

The next day, he taught physics majors two methods of solving equations. The inspiration value of the task dropped sharply compared to the previous day. In the afternoon, he simply went to the library and read professional books for three hours, which only brought about two points of inspiration increase.

【Task 1】

[R\u0026D project name: Common solution of specific partial differential equations (difficulty: B). 】

[Inspiration value: 98. 】

Looking at the data displayed by the mission system, Wang Hao sighed for a long time. He still chose to give up temporarily. Anyway, he was only short of two points of inspiration. It might be enough to go to Hangzhou Lake to give a lecture, even if he had enough before leaving. One hundred, and there is no time to study it at all, we still have to wait until we come back from Hanghu.

The research on 'Partial Differential Equations' does take a lot of time.

Wang Hao thought about it carefully, and thought that it was not a matter of difficulty, but the most important thing was that it contained too much content.

Partial differential equations are a large category of research.

This is not like a math problem, as long as you solve it, it contains a lot of content, which means that you need more knowledge and foundation, and more inspiration directions.

He had some expectation of what would happen.

After coming out of the library, Wang Hao went to the Academic Affairs Building to find the Academic Affairs Section of the School of Science, and made a report for a substitute class. The course lecturer finds someone to substitute for the class, and he has to go to the Academic Affairs to make a record and report. Substitute lectures for one or two classes Nothing, the main thing is that some courses are very difficult, and you can't just find a teacher to teach them for you.

Zheng Yaojun asked Wang Hao to do the course report on his behalf. He also explained that Wang Hao is a doctor of mathematics from Donggang.

It was easy for Wang Hao to ask Zheng Yaojun to speak for him.

Several people in the Academic Affairs Department knew Zheng Yaojun, and a director surnamed Zhu suddenly said, "Zheng Dazui, right? No problem."

Several people in the office laughed out loud.

"Zheng Dazui?"

Wang Hao thought about it carefully, and felt that the nickname of "Big Mouth" was indeed so appropriate for Zheng Yaojun.

If you don't say it, you really haven't noticed that Zheng Yaojun's mouth is really big.

"It's wrong to laugh at other people's looks, it's wrong to laugh at other people's looks, Zheng Dazui, Zheng Dazui..."

Wang Hao walked out thinking about it in his heart, and couldn't help laughing when he reached the corridor.

in the office.

As Wang Hao walked out of the room, the topic immediately changed from Zheng Yaojun to Wang Hao. There was a female teacher wearing glasses, with an inexplicable light in her eyes, "That is Wang Hao? I just heard of it before. How young!"

Others chirped, "He made a mistake in scientific research, made news, and only signed a one-year contract with the school."

"Donggang's staying doctor!"

"How else should I put it? A talent is a talent. I heard from Li Ming that he published three papers in one go, and they were published together in top-ranked international journals."

"Several professors from the Faculty of Science, plus Director Zhu, and the dean, immediately decided to give him a special promotion!"

"..."

Wang Hao left the academic building and had dinner in the restaurant.

Then, go home.

He opened the quest system and checked it out. After thinking about it for a while, he decided to create a quest——

【Task 2】

[R\u0026D project name: Fourier transform to improve multiplication (difficulty: B). 】

[Inspiration value: 0. 】

[The accumulation of inspiration points reaches 100 points, which can be consumed at one time to assist in obtaining research and development-related inspiration and knowledge. 】

[Task settlement, get teaching currency rewards. 】

really!

B-level difficulty!

The improvement of multiplication by Fourier transform is a problem that the predecessor thought about during his Ph.D., hoping to improve the "multiplication algorithm of large numbers" with Fourier transform as the core.

This is not a new subject.

The fastest existing 'large number multiplication algorithm' is related to the introduction of the Fourier transform algorithm. It was completed by two mathematicians half a century ago. Log (log n) multiplication of single digits' to realize the method of multiplying large numbers.

Fifty years ago, the multiplication algorithm of large numbers used the method of 'decomposing the multiplier of large numbers into smaller parts'.

Compared with the old method, the new method simplifies about 165 trillion extra steps when calculating the multiplication between two billion-digit numbers.

However, the new method is not new either.

In the past 50 years, information technology has been greatly developed, many fields need to multiply large numbers, but there is still no breakthrough in the research of multiplication of large numbers.

The predecessor has carefully studied the multiplication algorithm of large numbers, and believes that it can find a "more aesthetic", "simplified and elegant" way to introduce the Fourier transform algorithm to perform the operation of multiplication of large numbers.

Obviously.

It is not easy to do research and development that the system judges as 'B-level' difficulty.

The predecessor, gave up.

Wang Hao thinks he can give it a try, and he is going to give a speech at the R\u0026D center of Abayun. He must be facing a large number of algorithm engineers. The content of the explanation is also related to the discrete Fourier transform algorithm, and he may be able to get a lot of relevant inspiration. value?

...

The time came to the second day.

A plane took off directly from the West Sea to Hanghu, and it took more than three hours to arrive at Hanghu International Airport.

Wang Hao got off the plane with his luggage.

When he walked out of the airport exit, he saw a sign holding his name, and then walked over and asked, "Wait for me?"

The visitor took a look at Wang Hao, "Teacher Wang Hao?"

Wang Hao nodded.

The visitor breathed a sigh of relief, and stretched out his hand, "I'm so sorry, I didn't expect you to be so young. My name is Zhang Bin, and I came here to pick you up."

"let's go."

Zhang Bin drove Wang Hao to the hotel.

On the way, the two chatted.

Zhang Bin is not a full-time driver, but an algorithm engineer. The company's rank is very high, at the same level as the manager of the technical department. He is responsible for picking up Wang Hao, just hoping to have a common topic.

He also praised Wang Hao's achievements, "I read two papers carefully and studied them with my colleagues."

"We are sure that this new method of building data models can greatly improve the efficiency and accuracy of data analysis."

"To be honest, I thought it would be an old professor, but I didn't expect him to be so young."

Wang Hao smiled.

The two talked all the way to the hotel first, and after putting things away, they went to the R\u0026D center.

Several people were waiting at the door.

As soon as Wang Hao got out of the car, he felt the enthusiasm. Several people gathered around to shake hands and make introductions. The leader was Tang Jianfeng, the dean and direct person in charge of the R\u0026D center, but the main communication was with Feng Youlai, the technical director.

Feng Youlai really deserves to be the "technical director". He talked about what he didn't understand in the paper without saying a few words after seeing Wang Hao, and also chatted with him about the fields where the new method can be used.

The former is nothing.

Wang Hao doesn't know much about the latter. After all, he is a doctor of mathematics, not a doctor of informatics. At the same time, he has no relevant work experience and doesn't know much about applications.

Feng Youlai also discovered this problem, so he simply talked about technical and algorithmic content.

Wang Hao was entertained to the lounge, and continued to chat with Feng Youlai for a while, making arrangements to lie down and have a rest.

Five o'clock, dinner.

He went to the restaurant of the R\u0026D center with others, and after eating something, he went to a new hall to prepare.

When everything is ready, the time is almost up.

Wang Hao went to the front podium, just entered the venue and took a look outside, suddenly became a little nervous.

He's usually not nervous...

Now is a very special situation.

Looking outside, it feels like a sea of ​​people, several times more than the students in the classroom.

The place he wants to go is like a stage under the lights.

The scene is a bit like the scene of a large company's product launch event. It should be the company's CEO or something, but he is just here to give an academic report...

It's a bit exaggerated!

When he walked slowly to the middle podium and looked down the stage, Wang Hao suddenly felt that he had lost a lot.

An academic report speech in such a scene costs 200,000 yuan to appear?

The price is getting lower!
