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

December 2016, 1.

The world is big and big things are happening every moment.

At that moment, several major events were happening, which were related to a young man named Wang Donglai.

The first thing is that with the strong support of BYD and Tangdu City in terms of money and manpower, the semi-solid-state battery production line was successfully put into operation.

Brother Boatman knows very well what semi-solid-state batteries represent. Even though there is no way to achieve large-scale mass production now, its excellent performance is already able to beat other new energy vehicle brands on the market.

Whoever can be the first to use semi-solid-state batteries will occupy a large market share.

Therefore, Brother Boatman paid a huge price to win the cooperation on semi-solid-state batteries.

This time, the semi-solid-state battery has been pre-ordered by major mobile phone manufacturers before it even comes off the production line. There are so many orders that if the current production line speed is maintained, it will not be able to meet the needs even if it is fully produced until next year.

There is only one way, which is to add production lines and expand production scale.

Of course, some people believe it, while others do not, and think that this so-called semi-solid-state battery is a complete lie from China.

Just like the dragon chip incident back then, it was a complete scam.

The second incident happened in Demon City.

Center International.

Chip production super factory.

As one of the top semiconductor companies in China, although Central International is nothing special in the world, it has a different status in China.

At this moment, a large number of company executives and some relevant leaders of Demon City gathered in the super factory.

The purpose of so many people gathering here is to witness the application of "advanced packaging" in China.

Although Wang Donglai had previously come up with advanced packaging technology and had already proven it.

But it has not been applied on a large scale yet.

After paying a certain price, Center International obtained the copyright of advanced packaging from Wang Donglai.

After all, it is a large domestic semiconductor company and it still has talent.

After several months of study and exploration, the first high-performance chip belonging to China and the core international will be born.

Although it is not as good as the current mainstream chips, it is not much worse.

If it is proven to be mass-producible, the significance of "advanced packaging" will be enormous.

The importance of the semiconductor field in today's modern and intelligent era is something that anyone with a normal IQ can understand.

Let's use a simpler example to illustrate.

That is, as long as the country has a 65-nanometer lithography machine, it will mean military independence. There is no need to worry about problems with military equipment at critical moments, and the practicality of military weapons can be guaranteed at any time.

Many weapons in the military field are no longer the original small biubiu and big pengpeng. There are all kinds of intelligent weapons, which work together to form a complete military system, and none of them can be missing.

The more advanced the function, the higher the intelligence, and the required chip needs to have higher performance.

If there are only one or two machines, even if the yield rate is very low, they can be manufactured by smashing them.

But of course there cannot be only one or two weapons, so the method of using funds to buy them will not work.

This is just the change brought about by the 65-nanometer lithography machine.

According to Moore's Law, ICs of the same specifications can be produced on wafers of the same area. With the advancement of process technology, IC output can double every year and a half. Converted into cost, the cost can be reduced by 50% every year and a half, and the average annual cost can be reduced by more than 30%.

As Moore's Law extends, IC technology advances one generation every year and a half.

65 nanometers can only be considered excellent for a period of time, but as process technology advances, better chips will naturally appear.

Once my country has achieved 28-nanometer lithography, it will mean industrial independence.

There is a very counterintuitive little-known fact: industrial products such as air conditioners, refrigerators, washing machines, and automobiles have been in the world for more than a hundred years. Logically speaking, they are already mature products that cannot be more mature, but many countries are still unable to complete independent manufacturing and production.

Industrial autonomy means that once we decouple from the West and are subject to technological sanctions and equipment restrictions, the country can still produce and sell on its own.

Going further, once the 14-nanometer lithography machine is reproduced, it will mean that the domestic electronics industry has entered the stage of formalization.

All kinds of electronic industries such as mobile phones, computers, monitors, CPUs, GPUs, etc. can immediately get rid of foreign sanctions and restrictions.

Below 14 nanometers is 7 nanometers. Once achieved, it will mark China as a world technology center.

And this is the importance of the semiconductor industry.

The photolithography machine is the brightest jewel in the crown of industry. It is naturally impossible to surpass it in a short period of time. Therefore, "advanced packaging" has become the only hope for overtaking on the curve.

Soon, the first chip designed using the "advanced packaging design solution" came out of the assembly line.

It was taken for testing by relevant staff as soon as possible.

Everything had been prepared in advance, so the testing was very fast.

The result was not surprising at all: the chip was successful and the performance improved by 53%.

Wang Donglai naturally could not hear the cheers from the Central International Chip Production Super Factory.

The third incident happened abroad.

News from the international market has it that Siemens will spend $45 billion to acquire Mentor Graphics.

Once the acquisition is successful, it will mean that the international EDA industry will undergo tremendous changes.

However, this will not affect Wang Donglai for the time being.

At this moment, after determining the development route of Galaxy Technology, Wang Donglai came to the Astronaut Research and Training Center under the Aerospace Group.

"The selection of astronauts is a long and rigorous process. First, they need to pass basic condition selection, medical selection and psychological selection, which includes clinical medical examinations, physiological function examinations and psychological assessments."

"During the selection process, basic qualification review and preliminary clinical experience will be conducted on the candidates' personal data and files to screen out those with obvious diseases and functional impairments."

"The re-selection will also involve a comprehensive examination and assessment of those who have passed the preliminary selection. The final selection stage is the assessment and admission stage, during which the candidates will be further examined."

"The selection criteria for our country's astronauts are so stringent that we can't say we can only pick one out of a million, but we can definitely say we can pick one out of a hundred thousand!"

The aerospace field is relatively closed and rarely cooperates with some universities outside.

But Wang Donglai is different.

Not to mention Wang Donglai's status as an academician at that time, his achievements in mathematics alone were enough to make experts in the aerospace field feel good about Wang Donglai.

Not to mention, Wang Donglai also has some connection with the aerospace field, so it is not difficult for him to visit the scientific research and training center.

At this time, the person explaining to Wang Donglai was Director Song Lin of the training center.

When talking about the stringent selection criteria for astronauts, Director Song Lin's face showed a sense of pride.

The selection of astronauts in our country is indeed extremely harsh.

The applicant must be between 25 and 35 years old, 1.60 to 1.72 meters tall, 55 to 70 kilograms in weight, and have more than 600 hours of flight time. These are only the preliminary selection criteria.

The screening cycle is as long as two years, with numerous procedures and complicated items. Its strictness is unprecedented, and even family members need to undergo physical examinations.

There are some things that Song Lin did not say, but Wang Donglai has seen related articles.

That year, China carried out its first manned space mission.

A total of more than 3000 fighter pilots participated in the preliminary selection, and finally only 14 were left, with an elimination rate of over 99%.

And not all of these 14 people flew into space in the end.

This shows how rare astronauts are.

“It is precisely because of this attitude that our country’s aerospace industry has been able to develop so well and so quickly.”

"I have always believed that the future of the universe will be led by us Chinese people."

Hearing Wang Donglai say this, Song Lin suddenly became curious.

In the past, when people heard about the selection criteria for astronauts, they were either shocked or envious.

However, Wang Donglai did not do so. Instead, he said this sentence calmly and with confidence.

Curious, Song Lin asked, "Academician Wang, I'd like to hear your opinion. Why do you say that?"

"It's simple. You can tell the difference between us and the West from the name."

"We call them astronauts, but they call them cosmonauts. Although the meanings are similar, the spirits are completely different."

"Don't underestimate the small title. It reflects the broad-mindedness and courage of our Chinese nation."

“These things may seem insignificant and usually have no effect, but when they really show their effect, it means we have succeeded.”

"Astronaut and space navigator, Director Song might as well think carefully about which title is more impressive and profound."

When Wang Donglai saw the hint of pride on Song Lin's face, he knew what kind of person this was, and his words were the right remedy for his condition.

These words immediately made Song Lin smile happily.

"Academician Wang is indeed worthy of being an academician. I really hadn't thought about this. I had always thought it was a translation problem, but I didn't expect there would be such a hidden story behind it."

"Astronauts, astronauts. The more I listen, the more I feel that astronauts are more impressive."

A strong smile appeared on Song Lin's face as he savored the title of astronaut.

At this time, the two also walked to the training ground.

Song Lin also came back to his senses and introduced himself to Wang Donglai with a smile.

"Academician Wang, I just mentioned the selection criteria for our country's astronauts. Now let me talk about the training content of our country's astronauts. Academician Wang, don't worry, these things are not confidential and are not against the rules!"

I made a small joke to liven up the atmosphere.

It was obvious to the naked eye that Song Lin's attitude towards Wang Donglai had changed from being unfamiliar and polite at the beginning to becoming more friendly.

"Our international astronaut training is comprehensive and systematic, aiming to comprehensively improve the astronauts' abilities. The training subjects include basic theory training, physical training, psychological training, space environment adaptability training, life-saving and survival training, and space professional technical training, such as extravehicular activity technical training and rendezvous and docking technical training, flight procedures and mission simulation training, large-scale joint exercises, and 24 other types of training."

"In addition, astronauts also need to participate in various engineering development and test activities such as man-ship joint tests, man-ship station-ground joint tests, and long-term manned comprehensive simulation verification experiments, and deeply participate in the preparation of flight manuals and plans."

"These things sound complicated, but they are not the entire training content of astronauts."

"Because of the special environment of space, astronauts must undergo special environmental adaptability training to adapt to the extreme conditions in space, including overweight endurance and adaptability training, vestibular function training, landing impact experience training, neutral buoyancy tank training, etc."

"The purpose of these trainings is to enable astronauts to withstand greater overloads during the ascent and descent of the spacecraft, improve vestibular function stability, prevent space movement and collapse, and master body movement and posture control in a simulated weightlessness state."

"Finally, there is special training for extravehicular activities, including special training such as extravehicular procedure training simulators, extravehicular suit experimental chambers, and simulated real-life training devices. There is also a more important training, which is lifesaving and survival training."

"After all, rocket launches and returns are extremely dangerous activities. No one knows whether they will encounter sudden dangerous situations. In order to deal with these possible emergencies, this special training was developed to enable astronauts to have the ability to survive in harsh environments."

While introducing everything to Wang Donglai, Song Lin took Wang Donglai towards the training center.

Soon, a large number of various machines appeared in front of Wang Donglai.

"Academician Wang, this is a manned centrifuge, which is the nightmare of most astronauts. It is also this equipment that has eliminated many potential astronauts."

As he spoke, Song Lin took Wang Donglai into the control room.

This was the first time Wang Donglai came to such a place. In his previous life, he had only seen it on the Internet.

I couldn't help but feel a little excited and became more active.

Song Lin noticed the change in Wang Donglai and didn't find it strange.

At first, when Song Lin learned that he had to receive Wang Donglai and give him explanations, he was somewhat reluctant.

After all, in his opinion, this was a complete waste of his time to satisfy a young man's curiosity.

However, as he communicated with Wang Donglai, Song Lin began to feel favorable towards him.

If it were other visitors, Song Lin would never bring them into such a place. He would just take a look from the outside and give a few words of introduction.

"Director Song, do we have a full set of astronaut training equipment here?"

After taking a close look at the operating table of the manned centrifuge, Wang Donglai turned around and asked Song Lin.

“Well, we have them all here!”

"The manned centrifuge is the machine in front of you. It has a three-dimensional space ring, an electric swivel chair, an impact tower, a diving pool, a simulator, a test chamber, etc. It can do all the training except survival and life-saving training."

Song Lin reported his family's assets as if he knew everything about them.

Hearing Song Lin say this, Wang Donglai nodded.

At this time, Song Lin suddenly seemed to remember something, and said with a smile on his face: "Academician Wang, today is really a coincidence. A group of pilots will come to select astronauts this afternoon."

"Academician Wang, how about staying until the afternoon to see the astronaut selection process?"

Wang Donglai thought about it and nodded in agreement. (End of this chapter)
