When I am reborn, I just want to be a top student

As Galaxy Technology grew, Wang Donglai had more and more things to deal with.

Although a project leader will be appointed, many things still have to be decided by Wang Dong.

For example, the processing of packaging technology, and the research and development of artificial intelligence medical assisted diagnosis systems.

Compared with the founders of other companies, Wang Donglai is the absolute soul of Galaxy Technology.

At present, many technologies of Galaxy Technology are developed by Wang Donglai, or he plays a major role in them.

It can be said that if there was no Wang Donglai, there would be no Galaxy Technology today.

This is not only known to Wang Donglai, but also to other employees of Galaxy Technology.

In the semiconductor field, although Zhang Rujing rejected Wang Donglai's recruitment, he still showed his goodwill and was willing to help with some things.

Wang Donglai had actually anticipated this, and could only say that he was neither very happy nor very disappointed.

Once the packaging technology test is passed, the next thing will be easy.

Utilize domestic semiconductor technology and packaging technology to produce qualified chips.

Whether it is a drone, an artificial intelligence medical assisted diagnosis system, etc., a large number of chips are required.

These chips don't necessarily need to be the most advanced.

The performance of the chip will be improved through more advanced algorithm programs and packaging design solutions.

The only downside to doing this is that it will cost a bit more.

And this is not a problem at all for Wang Donglai.

Because whether it is drones or other products, they are all high-net-profit products, and simply increasing the cost of chips will not have much impact at all.

After dealing with this matter, Wang Donglai continued to study artificial intelligence software.

At this moment, an email from a bald eagle overseas made Wang Donglai stop.

"Congratulations, Professor Wang! No one in our country has ever won the Adams Chemistry Prize!"

Yao Qizhi congratulated Wang Donglai excitedly.

Wang Donglai looked calm and indifferent, and did not seem elated about winning the award.

“Not winning an award doesn’t mean we are worse than white people, it just means our academic voice is not as strong.”

“This award is actually just average!”

Wang Donglai spoke calmly, showing no sign of taking the award seriously.

The smile on Yao Qizhi's face froze. He didn't expect Wang Donglai to react like this.

This is also because the two of them don’t spend enough time together and don’t know each other well enough.

If it were the people at Tangdu Jiaotong University, they would not say this when they learned about the award.

After a short silence, Yao Qizhi said with some emotion: "You post-90s people are really young people. There is a huge generation gap between me, an old guy, and you."

"The Adams Chemistry Award is an important award in the field of chemistry. You don't know about this award, do you?"

Hearing Yao Qizhi's half-joking words, Wang Donglai immediately said, "How could I not know this? The Adams Chemistry Award is an award of the Bald Eagle Chemical Association. It was jointly established by the Bald Eagle Organic Synthesis Co., Ltd. and the Bald Eagle Organic Reaction Co., Ltd. in 1959, and co-sponsored by these two institutions and the Organic Chemistry Department of the Bald Eagle Chemical Association. The name comes from the Bald Eagle organic chemist Roger Adams, expressing his respect for him for several years."

"This award has been given every two years since 1995 to scientists who have made outstanding contributions in the field of organic chemistry."

"Of the 24 winners awarded so far, nearly half have won the Nobel Prize in Chemistry."

Wang Donglai spoke out this information in one breath without even pausing.

Yao Qizhi was also a little surprised when he heard Wang Donglai's story.

"Since you know that nearly half of the winners of this award can win the Nobel Prize in Chemistry, aren't you tempted?"

"You know, this is the Nobel Prize!"

Yao Qizhi looked at Wang Donglai curiously and asked.

Shaking his head, Wang Donglai acted very calm and said, "To be honest, I am a little tempted, but I hope that such an authoritative award can appear in China."

Yao Qizhi smiled bitterly and said, "That's going to be difficult!"

"Nothing is difficult if one sets his mind to it. In fact, as long as domestic researchers can change their mindset, it may not be difficult to achieve this. You know, our population of high-quality people is one of the best in the world. If domestic scholars work together, the value of these Western awards will plummet, and it will not be surprising if they become a farce in the end."

"But it's so difficult to do this!"

Wang Donglai said with some emotion.

Yao Qizhi also nodded in agreement in silence, saying, "I understand your patriotism, but academic issues cannot be resolved with patriotism alone."

"Development is the only way forward. As long as our country's technology becomes stronger and stronger and more and more talents emerge, the academic discourse power will naturally shift to us. At that time, we will be the ones to set industry standards."

"So are you going to Bald Eagle for the awards ceremony?"

Finally, Yao Qizhi asked.

Wang Donglai also thought about it for a while, then nodded and said, "Go."

The reason why Wang Donglai chose to go to Bald Eagle to receive the award was because he wanted to recommend lithium-sulfur batteries and more products of Galaxy Technology.

As for his own safety, Wang Donglai was not worried.

"Well, if you go and receive this award, you will break the domestic record again. This will bring glory to the country and will be good for you as well."

Yao Qizhi nodded and said so.

……

May 27th.

The time for going to the Bald Eagle has been set. This time Wang Donglai is not going alone, but a professor from Tianjin University is going with him.

The professor from Tianjin University is called Ruan Wei. The reason why he went to Beijing with Wang Donglai was because he took the initiative to contact him. Because Professor Ruan specialized in filter chips, Wang Donglai agreed to go to Bald Eagle with him.

In fact, Wang Donglai knew that Professor Ruan was probably here for him.

Either he is after his money, or he wants me to use my math knowledge to help him with project research.

airport.

At the agreed location, Wang Donglai met Professor Ruan.

"Professor Wang is so young!"

As soon as Professor Ruan saw Wang Donglai, he took the initiative to greet him enthusiastically.

"Professor Ruan, you are too polite. You look very young. You seem to be only in your thirties."

The sedan chair is carried by many people. Professor Ruan took the initiative to show his goodwill, so Wang Donglai would naturally not reject him.

After exchanging pleasantries, they all sat down.

Unlike Wang Donglai, Professor Ruan did not go to Bald Eagle alone, but was accompanied by his lover Fan Lili.

After a brief introduction, Professor Ruan took the initiative to talk to Wang Dong and said, "Professor Wang, I heard that you went to Bald Eagle to receive the Adams Chemistry Award. That's amazing!"

"Professor Ruan, you are too polite. I am also a little surprised by this award!" Wang Donglai acted very calmly. After answering, he asked, "What is the matter with Professor Ruan going to Bald Eagle?"

Ruan Wei smiled and said, "There is an international microwave academic exchange meeting in Bald Eagle, and I was invited to attend. It just so happens that I came here with my wife to take a look."

"Oh, by the way, I'm researching filters. I founded a company called Novus Systems Co., Ltd. with my friends. Our main product is FBAR filters."

"Professor Wang, you are a genius in mathematics. I heard that you are also interested in semiconductors. If you don't mind, we can talk more."

"To be honest, I often encounter algorithmic problems during my research. It would be great if I could have a math genius like Professor Wang to give me some pointers. I wonder if Professor Wang could give me some pointers when he's free?"

Ruan Wei kept a very humble attitude and did not show off in front of Wang Donglai because of his achievements and age.

This time he took the initiative to find Wang Donglai and went to Bald Eagle with Wang Donglai in order to build a good relationship along the way so that he could ask for help when he encountered mathematical algorithm problems later.

Sometimes, top mathematicians can play a very important role and can be said to be excellent assistants.

The filter chip looks small, but it actually has a wide range of uses. The mobile phones we use in our daily lives use filter chips. In addition, there are various electronic products that need to receive signals.

The principle is also very simple, which is to filter radio signals and reduce external interference to ensure communication quality.

It plays an extremely important role in communication.

"Professor Ruan, you are too polite. Let's communicate and learn from each other. To be honest, I am also very interested in filter chips." Wang Donglai did not speak in an overbearing manner, but said this humbly.

Ruan Wei breathed a sigh of relief when he heard Wang Donglai's answer.

Seeing that Wang Donglai was so young, to be honest, he was a little worried that Wang Donglai would be difficult to talk to and would reject his proposal, which would make him lose face.

Fortunately, such a thing did not happen.

"I didn't expect that Professor Wang would also be interested in filter chips. Then I'll talk to Professor Wang about it."

Ruan Wei started talking to Wang Dong with some excitement.

"First of all, we need to know what a filter chip is. If sound is to be transmitted thousands of miles away, it must first be converted into high-frequency radio waves. The information is encoded into a sine wave with billions of peaks per second. The opponent's mobile phone receives and restores it without any distortion. This is the ability of radio frequency devices. The core component of radio frequency devices is the power amplifier chip, also called a radio frequency chip."

"Another core component of RF devices is the filter, which can be mainly divided into filters using surface acoustic wave (SAW) and bulk acoustic wave (FBAR/BAW) technology. The filter can remove signals outside the target frequency band and is a very basic circuit device."

"High-end filters use the piezoelectric effect principle and introduce sound waves to work. Their substrates and coatings are made of new materials with high processing precision, involving thin film deposition and micro-mechanical processes."

"Compared with surface acoustic waves, bulk acoustic wave filters have obvious advantages in performance. They can allow mobile phones and other communication equipment to filter radio signals to improve call quality. They are mainly used in mobile electronic devices such as mobile phones, tablets and GPS."

"At present, many high-end equipment in China use the filter chips I developed!"

When he said this, Ruan Wei's face was full of pride.

Wang Donglai also praised him a few times out of support. Ruan Wei was not the kind of person who would get carried away easily, but facing Wang Donglai's praise, he couldn't help but feel proud.

After all, Wang Donglai's academic achievements are extraordinary.

Not only in the field of mathematics, but also in other fields such as computers, he has achieved amazing results.

Therefore, being praised by Wang Donglai naturally made Ruan Wei feel very proud.

"High-end filters have very high technical requirements in terms of center frequency, cutoff frequency, linearity, sensitivity, etc., so they have always been monopolized by foreign RF device giants such as Qorvo. However, this is history now, and domestic filters have developed."

Wang Donglai thought about this and said subconsciously, "Professor Ruan, this technology should also be used in military and national defense communications technology. It should be considered a sensitive technology involving confidential information. Will it have some impact?"

Ruan Wei waved his hand indifferently and said, "Professor Wang is right about this, but it has nothing to do with my company. The products we produce are all provided to enterprises."

"Professor Wang, you probably don't know how important a filter chip, which is less than one square millimeter, is to a smartphone. It can be said that without this chip, both smartphones and old phones will become bricks and lose their communication functions."

"The country's annual demand for more than 10 billion chips is overwhelmingly imported, especially high-end filter chips, which are completely dependent on foreign imports. A chip costs tens of yuan, but the cost is less than one yuan. Even high-end chips are only five or six yuan. Just because we can't produce them, we sell them at such a high price."

Wang Donglai didn't expect Ruan Wei to have such an idea. He was stunned at first, then he reacted.

The Chinese are not fools. They are not willing to be exploited by foreigners and treated as suckers.

Chips are sold at high prices abroad and reap the profits in China. No one is willing to accept this, but as they are weaker than others, they can only endure it and dare not speak out.

But once a breakthrough is achieved, one naturally does not want to swallow this humiliation.

Therefore, Ruan Wei’s emotions are completely understandable.

Nodding, Wang Donglai changed the subject and said, "Professor Ruan, why don't you talk about the filtering algorithm? I'll see if I can help you, in case you run into problems later and I don't understand the algorithm."

Ruan Wei smiled and said, "There are not many filtering algorithms. There are limited filtering, median filtering, arithmetic mean filtering, recursive mean filtering, median mean filtering, limited mean filtering, weighted recursive mean filtering, de-jitter filtering, limited de-jitter filtering, first-order lag filtering, etc...."

From the waiting hall until he got on the plane, Ruan Wei excitedly and enthusiastically introduced his major to Wang Donglai.

Wang Donglai was also very studious. Not only was he able to keep up, he also often discussed things with Ruan Wei, which made Ruan Wei even happier. (End of this chapter)
