An Feng turned back in disappointment and took two drinks.

"Here you go!"

"Thank you." Joanna took the drink, saw the disappointment in his eyes, touched him with her arm, and whispered, "Don't you feel bored?" ”

"Yes. I thought it was the kind of wonderful college student prom in the movie. An Feng rarely hides his emotions in front of Joanna, and they have always been good friends who don't talk about anything.

"The motive is not pure." A Chinese word popped out of Joanna's mouth, and then she changed her English with some schadenfreude: "Didn't get it?" It's all a bunch of nerds, everybody is about to graduate, pursuing realistic ideals and doesn't like bombastic lads. ”

"What you say has multiple meanings." An Feng was bored and talked nonsense with her, "First, you say 'all', which means that you admit that you are also a nerd, and then 'talk about it', I want to say that I was wronged, I'm very serious, okay?" The last, the lad...... Thank you for that! ”

Joanna gently covered her mouth and said, "I can't smile anymore, the makeup on my face is going to be messed up." ”

"You're beautiful without makeup." An Feng took a sip of the drink, then raised his chin and motioned for Joanna to turn back: "Your friend is looking for you." ”

Joanna glanced back at a few girls and said hello, they invited her over, Joanna turned her head, and before she could speak, An Feng said very understandingly: "Go quickly, don't think about my feelings, I'll treat this place as a cafeteria tonight, don't say you know me." ”

Joanna held back a laugh and left a sentence: "I'll invite you to tea tomorrow." ”

An Feng listened to the eloquent talk of people from all walks of life: being a general manager, the experience of being a CEO, etc., and then the dance began, the music played, some people were inviting dance partners, and some were still chatting. He came to the table and walked around with his plate and fork, his stomach full.

"I'm sorry." A voice came from behind him, An Feng turned around, it was an Asian with glasses, wearing a gray suit, and also holding a dinner plate in his hand.

"Blocking you?" An Feng took a step back.

"No, I'm trying to ask, are you from China?" The Asian kid asked.

"Yes, I'm from the South." An Feng said in Chinese.

"I'm from the north. I mean, I don't think you're Korean. The other party also changed to Chinese and spoke with a northern accent. He wiped his hands and stretched out towards An Feng.

An Feng shook hands with him: "Can the stick be as tall as mine?" ”

The other party smiled and agreed: "That's right, the stick does not have your temperament." My name is Song Wenrui, a graduate student of UCB School of Engineering, graduating next year. What about you? ”

"Me?" An Feng laughed, "I'm not an international student, I've graduated a long time ago, and I'm here to make up for it this time." ”

"Oh?" Song Wenrui also smiled, "It's really strange, usually girls come here to accompany the boys from the fraternity, and it's rare to see people from other schools...... Gentleman. ”

"How so?" An Feng asked him.

Song Wenrui glanced at the gradually lively crowd on the dance floor and said: "Most of the people here are good learners, commonly known as nerds, who are not very communicative and not very popular. ”

"Not necessarily, look at a few life winners over there!" An Feng looked at the girl beside the frustrated man, and felt a little like flowers and cow dung.

Song Wenrui saw his thoughts and said with a smile: "Today's girls are smarter, and they like to find a dull boyfriend as a long-term investment, because nerds can rely on excellent grades to work in large companies after graduation, with excellent treatment, stable income, and a bright future." And those who are active, the handsome boys of the school team, who are loved and admired by girls, except for a very small number of those with family backgrounds who can go smoothly after graduation, the rest are not as good as the salary of nerds after graduation, even less than half. ”

An Feng feels that there is some truth, this is called reality. He said: "What about you, you know so thoroughly, don't you introduce the other half?" ”

Song Wenrui smiled a little shyly: "Not here, in a different place." ”

"Domestic?" An Feng asked.

"No, she's Chinese, in USC." Song Wenrui said with some pride.

An Feng understood: "It's not far. It's still close, and the feelings won't be rusty. ”

Song Wenrui glanced at him and asked, "Do you mind talking about your own work?" As a person who has come over, also give me a reference, and take less crooked paths. ”

An Feng shook his head: "I'm afraid I don't have much experience to pass on to you, because I am an investor, doing some business, and looking for other investment opportunities." ”

"Then your family must be very solid." Song Wenrui said.

"Sort of." An Feng smiled, "What about you?" Master's students in the School of Engineering should be in the category of computer science, right? Silicon Valley has a lot of multinational companies to choose from. ”

Song Wenrui smiled bitterly: "The major I studied is a bit ahead of its time and has market prospects, but the current lukewarm graphene, have you heard of it?" ”

Not to mention that he has heard of it, he probably knows more than anyone in the world, An Feng said without changing his face: "I know that new materials, known as 'silicon killers', as the core problem of processors, once the problem is solved and fully introduced to the market, AMD and Intel's silicon technology will usher in the end." ”

Song Wenrui said: "I like the term 'silicon killer'. However, it is estimated that in the next 5-10 years, graphene will be in a downturn. Its hot spot is that it can change the market, but there are many difficulties, its stability is insufficient, the cost of small area graphene has been greatly reduced, but large area is still very difficult......"

When the engineering man talks about this knowledge, he can't stop at all. What's even more fatal is that An Feng has recently unearthed these advanced techniques, and his views and theories are impeccable, which shocks Song Wenrui no less than the opportunity for a devout follower to meet God and ask him questions.

It's like meeting God.

What can graphene do? There are too many to mention. The most obvious is to replace silicon chips, such as a commercially available household microprocessor, which has a frequency between 2-3GHz, and the nature of silicon limits its leapfrog development. If graphene is used, it can easily reach more than 300GHz, or even 1000GHz, what does that mean? If a chip company masters this kind of technology now, it is no less than dropping a nuclear bomb in the chip market!

Think again, mobile phones, tablets, PCs, laptops, ...... All of them want to use this technology, and its influence is probably no less than that of Microsoft, which was born back then.

Is that enough? The use of graphene is far more than that, what is the current technical shackles of electric vehicles? Battery! Recently, Tesla's electric car, which is very famous, uses the same lithium-ion battery as a laptop.

Graphene can change all of this by making it into a supercapacitor with a large capacitance, long life, and a charging time of less than 10 minutes. It only needs to reduce the cost to replace lithium-ion batteries, and the electric vehicle revolution really begins. Including other electronic products, it is no longer a dream to charge a mobile phone once a week.

There are other fields such as military, electronic technology, etc., where graphene can bring about major reforms. Some people say that silicon was played in the 20th century, and charcoal should be played in the 21st century.

The two chatted a little dryly, Song Wenrui drank a glass of water, and said with a smile: "The future is very beautiful, but if you want to realize it, the reality is too cruel." ”

"How long do you think it will take?" An Feng asked.

Song Wenrui thought for a while: "I don't dare to give the exact time for full popularization, it's too far away." However, it will take five or six years to officially apply it at the earliest. ”

"According to you, this research work is not very clear at the moment."

Song Wenrui nodded: "It's like gambling, the time for the breakthrough of the technique is fast, and the people of us will be able to enjoy the benefits of the outbreak of the technique as soon as possible." If it's slow, and there will be a major breakthrough in a few decades, this life will be wasted. The development of science and technology will always sacrifice the youth of countless pioneers. ”

"Do you want to return to China or develop here after graduation?"

Although it was a little strange An Feng's question, Song Wenrui still said seriously: "The degree of attention in China is not very high, and the technical environment is not good enough. You know, a pioneer in skills means low pay and hardship, if you don't pay attention, I'm afraid there will be no future, so I choose to stay for now. ”

"Found a job?"

"Not yet, the big companies don't invest much at the moment, and the interns are treated very poorly. If I don't have enough time, I can only choose a more suitable one for the time being, and then I will talk about taking the work visa first. Song Wenrui said that this was quite helpless, and he had empty ambitions but did not show the stage.

An Feng's last question: "Are you willing to work for me?" ”
