1991 Starting from the core

Because he had completed the design of pagers in his previous life, Su Yuanshan knew that when the pager market was about to collapse, various pagers had been designed.

But at that time, even China was already entering the mobile phone era, and no matter how awesome your pager was, there was no market for it.

Seeing the surprised expressions on the two people's faces, Su Yuanshan smiled and said: "In my opinion, to make a pager attractive, it must have eye-catching and popular functions. You said, pay attention to the weather forecast How many people are there? How many people are paying attention to stocks? And these functions cannot be demonstrated yet.”

"But games and radio pagers are different. The clerk can demonstrate them immediately when they sell them, right?"

"Yes!" Dynasty Xinyi clapped his hands and became excited: "I'll go back and do it right away!"

"Yes, and these pagers with unique functions can enhance the brand image. As long as we insist on developing functions that are not easy for others to imitate, it will be easy to form a brand effect, and it will be more respectable when we take it out."

"At the same time, functional pagers like this also have self-propagating properties - when you look at the page, few people will ask you, right? But if you play games or listen to the radio with the page, people will definitely ask you what it is. The brand is so awesome... right?"

Wang Chaoxin nodded his head like a chicken pecking at rice.

…

After seeing the two of them off, Su Yuanshan lost interest in going back to sleep and began to review instead.

He studied almost entirely by himself this semester. He didn't even go to the teacher's office a few times, let alone the classroom.

In terms of skipping classes, he received a gold medal to avoid death, but in the final exam, it all depended on his ability.

What's more, he is now famous. The classmates also found out that there was another classmate in their class named Su Yuanshan, who was an outstanding person who was admitted without taking the exam as the grand prize winner of the programming competition.

What’s even worse is that I chose physics!

what does that mean? It means that this person is so awesome that he thinks he can stop learning programming.

With his reputation, Su Yuanshan couldn't afford to lose face if he asked the teacher to accommodate him.

Therefore, during the exam, Su Yuanshan was surrounded by a lot of people...

It wasn't until the results came out at the end of the month that Su Yuanshan let out a long sigh of relief.

Didn't finish in the top three, just happened to be fourth, and the difference was not many points. The wrong questions were mainly due to not listening to the teacher. As for the basics, he really learned it solidly.

After the winter vacation, Su Yuanshan returned to the Science and Technology Park and continued his three-point and one-line work.

Until the Spring Festival holiday comes.

Su Yuanshan still stayed in the science and technology park and in the laboratory.

…

"Well, Mom, I'll do an experiment and I'll be back in two days."

"Yeah! I know...please stop annoying me, okay! Mom!"

Su Yuanshan rubbed his greasy hair and almost lost his temper with his mother for the first time since his rebirth.

After hanging up the phone, Su Yuanshan walked out of the laboratory and looked at the science and technology park.

Today is already the 28th day of the twelfth lunar month, and in two days it will be the Spring Festival.

Yuanxin officially went on holiday the day before yesterday, and now only some local security and logistics personnel remain in the science and technology park. In addition, even the construction site in the distance became quiet.

There was no one anywhere as far as the eye could see.

At this time, Big Brother vibrated, Su Yuanshan took a deep breath and answered the phone.

On the phone, my father's calm voice came.

"What's wrong?"

"Dad, I know Mom cares about me. But she doesn't understand, you can understand. Sometimes when we try to seize the dawn, let alone eating and sleeping, let alone the Spring Festival, we will not hesitate to die..."

It is said that if you hear the Tao in the morning, you can die in the evening.

There was a long silence on the phone.

"Son, I have been in your situation, and I can understand you. But you have never been a father, so you can't understand me - go home."

Su Yuanshan held his eldest brother's hand slightly tightly.

He immediately realized that he was really going a little crazy because he couldn't peel off the graphene.

"Dad, no, I'll do it again. No matter whether it's successful or not, I'll be home before dinner. Well, I'll drive by myself. I can drive."

Hanging up the phone again, Su Yuanshan rubbed his face hard.

Continue to remove the tape.

The most primitive method of graphene is mechanical exfoliation.

Cut the graphite first and then stick it firmly with tape.

Then crash again!

The crystal layer that is torn off and stuck on the tape is composed of countless layers of graphene.

Then continue to use tape paper to peel off the tape with the crystal layer...

When you tear it to the end, you will get a two-dimensional carbon atom crystal with only one layer of atomic structure - graphene.

How to make it is so simple.

But its significance is so significant that it breaks the theory that "there are no two-dimensional crystals at room temperature" that existed seventy years ago - although this theory has been challenged by people.

Now it is Su Yuanshan who challenges it.

Graphene is invisible to the naked eye and difficult to see with an optical microscope.

But Su Yuanshan has a scanning tunneling microscope and can see this thing.

After taking a deep breath, Su Yuanshan put a piece of film that seemed to be successful under the optical microscope into the scanning tunneling microscope.

In an undulating atomic field, there is no overlap or bulge. This means that it is made of extremely thin crystals.

Su Yuanshan closed his eyes and clenched his fists.

He didn't cheer, just breathed softly.

Even at this moment, he had a thief-like mentality.

But soon, this mentality was crushed by him.

…

After putting away the tape and sealing it, Su Yuanshan went downstairs and rushed to the parking lot, drove out a Santana and returned directly to the Electrical Engineering Department.

When he saw his father, Su Yuanshan didn't say what he was doing, and his father didn't ask him. Even the mother seemed to have forgotten that he had been cruel to her before, and the whole family was harmonious, eating and chatting happily.

But Su Yuanshan did not continue to watch TV with his parents. He plunged into the study and began to study hard.

"Xiaoshan, why do I feel that you have been anxious lately and are not normal?"

Su Xinghe stood behind his son and saw that his son was studying with the original English textbook. He was happy for a moment, but immediately became worried.

Su Yuanshan put down the book and looked at the undisguised concern on his father's face. He pursed his lips and said with a smile: "It's okay, Dad. I want to learn more while I have the urge."

"But no matter how motivated you are, you can't go all out."

"No, I cherish my life very much." Su Yuanshan breathed out softly: "Dad, help me find a connection with P University. I want to go to the laboratory for a while and learn several experiments in condensed matter physics, especially low temperature. test."

"……good."

"Thank you, Dad." Su Yuanshan smiled slightly.

Su Xinghe smiled and shook his head, patted his son's thin shoulder, and said softly: "No matter what you do, I won't ask, but I will definitely support you."

"Hehe, it's mainly because I have some eyebrows, I'm sorry to tell you." Su Yuanshan said a little coyly.

His original plan was to drag his father along.

But he gave up the idea.

My father is engaged in integrated circuits, and now he is focusing on design, and he has nothing to do with graphene.

If you really drag your father, it would be disrespectful to him.
