Scholar’s Starry Sea

Professor Liu Yubo recently had an annoyance that made him feel a lot of hair loss, that is, he recently started to feel that even discussing with Wu Bin is a bit difficult.

Although when Wu Bin started asking him about graphene, he didn’t use an educator's attitude to discuss with him, because at that time Wu Bin’s views on graphene were already quite comprehensive. NS.

However, since Wu Bin started to study computational materials science, the problems he raised have become more and more complicated, which made him a little bit overwhelmed, and these problems have also given him new ideas.

On this day, Liu Yubo is sitting in his office looking at Wu Bin’s new article "Ultra-low voltage transformer loaded graphene fixed electrode for methanol oxidation reaction simple preparation"

The paper describes the use of pulsed current electrodeposition technology to prepare graphene-supported platinum nanoparticle electrodes, which are used in the electrooxidation of methanol in acidic media.

Electrodeposition technology can be said to have always been one of the important methods for preparing high-performance metal matrix composites based on low cost, because the coating has high hardness, excellent wear resistance and corrosion resistance. A lot of attention.

After reading the whole paper, Liu Yubo took a sip of strong tea and looked out the window. After a long time... he couldn't help but patted his forehead, "The child is still ahead of me after all."

When Liu Yubo saw this thesis report, the summer vacation was over, and freshman freshmen came to this brand new campus one after another.

At this time of the year, some graduated Senior Senior Sisters will also return to the University of Science and Technology, some will visit teachers, and some will see their Junior Brother junior sisters with whom they have a good relationship.

The most of these people are the previous members of the Mathematics Association.

In the mind of most people, the student union is the most like a microcosm of society in the university. The way members get along has always been the mainstream of love and interest. However, this kind of friendship has the longest shelf life.

This year is the same. Many people Li Yan didn't know appeared in the student union, but the seniors of the student union were very excited when they met them, and they seemed to have a very good relationship.

When chatting, these graduated seniors will tell them some of their experience in graduate school, or some who have already worked will talk about the development direction of the market.

Incumbent members of the Student Union will talk to them about the new things that happened on campus this year, including the issue of "science advances" by a freshman.

"Cowhide, I published a sub-news in my freshman year, so I can't go to heaven after graduate school?" Wang Gaofei, wearing a shirt, said in surprise. Because he was also from the hospital before, he was a little excited when he heard that he had such an enchanting Junior Brother.

"And it's still an independent work. I did it all by myself. When I first listened to it, I felt my scalp numb, just like listening to the Heavenly Book." Zhou Fanrong, Minister of External Relations Immediately hit a sentence.

"Then I really have to go and read it."

"Li Yan, you should have that journal, right?" Zhou Fanrong turned around and asked Li Yan.

Li Yan nodded: "Well, in the dormitory, I can bring it here at noon."

"Thank you first, you are the demon...Oh no, Wu Bin's friend?" Wang Gaofei asked.

"Well, they are in the same dormitory."

"Hahaha, is it particularly stressful to be in a dormitory with this kind of person?" Wang Gaofei asked with a smile.

"Fortunately, I can actually learn a lot from him." Li Yan answered with a smile.

"That's really a strange person. I used to have a student in my dormitory. I was under too much pressure. I always feel that this kind of person has worked so hard, and my hard work is still useless. "

"hahaha."

People in the Conference Hall burst into laughter.

At this time, Lu Ange of the Class Union Department suddenly took a picture of a person eating a watermelon in the corner and said; Now, do you want to see it?"

"Oh? Does he still do programs?" Mao Rui was taken aback for a while, "Isn't he from the hospital?"

"That's why I said he was a demon. It was a task given by Old Cao before. We were worried about whether we should come to you for help. Li Yan said that he has a friend who can try it. I tried, and I really got it done. A group of other hospitals who are doing big experiments are sharpening their knives. Once they know that it is his updated software, they will definitely be hacked to death."

"Interesting." Mao After Rui quickly gnawed the remaining watermelon, wiped his hands, ran to turn on the computer.

Others also leaned to the computer after they saw it. You must know that Mao Rui was also the ace player of Xinyuan, otherwise he would not be allowed to design this cheating program. , They are really curious what evaluation this Senior would give.

"bang bang bang bang..."

With a rhythm of keyboard percussion, Mao Rui quickly discovered Wu Bin's new design from the running program.

"Something, this kid has modeled the similarity of the program as a maximum weight matching problem of a bipartite graph, so that each node u on the left side of the bipartite graph represents a function of P1, and the right side... "

"Brother Mao, can you tell me something we understand?" Lu Ange patted Mao Rui's shoulder and asked with a heavy face.

"Generally speaking, this network flow model approximates the edit distance of the program instruction sequence. This model has a very high degree for students adding some useless code or deleting some printed debugging information when cheating. It even has a very good effect on the splitting and merging of large function codes." After saying that Mao Rui tapped the keyboard, "Expert!"

Then I didn’t wait for others to answer, Mao Rui. Rui looked at Li Yan and asked, "Can I see this person?"

"I can ask for you." Li Yan nodded.

"Just tell him that I want to get rich with him."

"Get rich?" Li Yan laughed, "He probably has no interest in getting rich, but if you want to get rich with him Discussing complicated procedures, I guess he will be more happy."

"hahaha, really fucking a University of Science and Technology person, excellent, then you tell him that I have a few hundred I want to discuss with him the big problem of the century that no one team can solve."

"Nothing wrong." After Li Yan finished speaking, he took out his mobile phone and prepared to make a call.

Qin Simeng, who had been listening at this time, suddenly opened the mouth and said: "That...Brother Mao, can I go together? I also want to increase my knowledge."

"Okay, come together, and listen to this will indeed help you in the future."

Mao Rui and Qin Simeng can be said to have met each other. They are both in the Faith Academy and in the Student Union. , Naturally very familiar.

"Thank you, Brother Mao, then." Qin Simeng said happily.

……

Wu Bin who does not start school has no effect on Wu Bin. At this time, he is working on his graphene in the laboratory daily, and he is a stranger When I was worried about my data, the phone in my pants pocket suddenly vibrated.

Take a look, Li Yan called.

"What? The problem of the century? The restaurant, right? I'm coming soon!"
