"You said an old academician came to see us?" Qin Ke put down his pen, raised his head from his desk, and looked at his assistant Chen Ya with some surprise.

Although with his current status and reputation, it is not surprising to have an academician visit him, but academician elders are always busy people. When something happens, they usually communicate by phone. Even if they are polite, they just send someone.

When students come to communicate, they rarely come to visit in person.

This is somewhat of a loss of status for an academician, let alone an old academician.

After all, no matter how famous they are, Qin Ke and Ning Qingyun are still young people in their early twenties, and they do not have the status of academicians.

Chen Ya nodded and handed over a business card: "This is his business card."

Qin Ke took it and looked at it, and saw "Song Shiliang, School of Materials, Xiaguo University of Science and Technology" written on it. He stood up immediately, pulled Ning Qingyun and said: "Put the papers first, let's go, let's go down first."

Meet Academician Song."

Ning Qingyun also saw the name on the business card, her beautiful eyes widened slightly, and she obviously did not expect that this old man would come to visit in person, so she quickly got up and ran down with Qin Ke.

Chen Ya was a little surprised. The name of Academician Song Shiliang was very unfamiliar. At least she had been working as a working assistant for Qin Ke and Qin Ke for almost three months, and she had never heard them mention it. Why did she go down to receive him as soon as she saw the name?

Naturally, Chen Ya didn't know the story that happened outside the National Science and Technology Awards Ceremony at the beginning of the year.

At that time, Academician Song Shiliang suffered a myocardial infarction on the way to the venue. He fell to the ground and almost died. Qin Ke, Ning Qingjun and other passers-by who were passing by offered a helping hand and quickly sent him to the hospital for rescue. Academician Song Shiliang escaped.

One calamity.

After Academician Song Shiliang woke up, he and his family contacted Qin Ke and Ning Qingyun several times to express their gratitude, and they became familiar with each other after going back and forth.

Later, after Academician Song was discharged from the hospital, because of poor health, he never returned to the school headquarters in the northwest to teach. Instead, he stayed at the Materials Research Institute of Charcot University in Beijing as a technical consultant. During this period, he also invited the two of them to his home for dinner.

And Qin Ke was very good at dealing with people. He would call Academician Song to greet him every year and festival, and the relationship between the two parties became even better.

It’s just that Academician Song Shiliang usually focuses on the fields of metal materials science such as high-temperature alloys, alloy steels, metal corrosion and protection, metal solidification theory, material fatigue and fracture, amorphous nanocrystals, etc. There is not much overlap with Qin Ke and his colleagues in the field of fluid mechanics.

We don't usually have close academic contacts.

However, Qin Ke and Ning Qingyun have been working on a topic on topological quantum computing recently, which involves the structure of some nanocrystals. They called Academician Song Shiliang for advice. The old academician said that he would study it in depth before replying.

Unexpectedly, only two days had passed before the old academician suddenly came to visit. You should know that Academician Song usually stays at the Materials Research Institute of Charcot University. He is a typical technical expert who lives in the laboratory and rarely goes out.

Qin Ke and Ning Qingyun guessed that the question they asked for advice might have been answered. In addition, the old academician came to the door in person, so naturally they had to rush down to receive him.

Because the Fluid Mechanics Laboratory has many confidential projects and is inconvenient for outsiders to visit, a reception room is set up on the first floor. No matter who comes, they are received there.

Qin pulled Ning Qingyun and took the elevator to the first floor. When he trotted to the reception room, he saw Academician Song Shiliang and one of his students sitting on the sofa waiting. He hurriedly went over and said: "Academician Song, I'm sorry, I didn't know what your specialty was.

Come to visit, otherwise I will greet you at the school gate."

Academician Song Shiliang stood up, shook hands with Qin Ke, and briefly introduced his students. Qin Ke shook hands with the doctoral student and said hello. The doctoral student was flattered and his attitude was extremely polite.

"Professor Qin Ke, Professor Ning Qingjun." Academician Song Shiliang's always somewhat rigid face showed a smile: "I understood the questions you two asked me two days ago, but the explanation is more complicated. I can't say it on the phone.

If it’s clear, I’ll come over and tell you in person.”

While Qin Ke asked his assistant Chen Ya to change into better tea, he helped the old academician sit down and joked: "You always just called us and asked us to come over. Now it's obviously us asking you questions, but you are asking you to run away."

Damn, you are deliberately making us feel uneasy tonight, so we can't even sleep."

Academician Song was not good at words, so he just smiled at the joke and said, "Do you have a projection here? I asked the students to prepare a ppt, and explain it to the ppt, so that it will be easier for you to understand."

Naturally, the reception room also considered that it would be used for academic exchanges, and the projection was quickly prepared. Academician Song Shiliang did not have any greetings, and directly said to the ppt: "The one you are asking about is a double-axis projection after adding trace amounts of lithium to the iron-arsenic crystal.

The problem of charge density wave stripes becoming particularly uneven is caused by the natural stress imbalance between crystal structures..."

Academician Song Shiliang gave a very detailed lecture. The doctoral students he brought along switched ppts and continued for almost half an hour.

"Basically, what I know about the relationship between crystal structure and natural stress is pretty much complete. Do you have any questions?"

Listening to the old man's hoarse voice and serious expression, Qin Ke was moved and hurriedly brought the reheated tea: "Academician Song, please take a sip of tea and take a break."

Academician Song Shiliang took a sip of tea and communicated with Qin Ke for more than ten minutes. He was sure that they had fully mastered the knowledge he had mentioned. He couldn't help but said with relief: "You two are also talented in materials science.

Very high. If you have the opportunity to work harder in this direction in the future, if you have any questions, you can contact me at any time. Okay, I'm going back."

Qin Ke quickly grabbed him and said, "Academician Song, it's almost noon. Qingjun and I will treat you two to a casual meal. Our teachers, Academician Jiang Weixian and Academician Guo Weiyang, are also here, and we just happen to get together."

Ning Qingyun also advised: "Academician Song, you just came here and didn't get much rest. It's not good for your health to go back now."

This chapter is not over yet, please click on the next page to continue reading! Academician Song Shiliang waved his hand: "No, no, no, I have a student's experiment to guide next, so you don't have to be polite to me."

Qin Ke repeatedly tried to persuade him to stay, but Academician Song Shiliang finally left with his doctoral students. When he left temporarily, he encouraged him warmly: "'Environmental material biochemistry' is jokingly called the 'Tiankeng professional direction', but no one can deny it."

, Materials science is the cornerstone of the development of human science and technology. I heard that you have built a quantum computing laboratory, which involves the direction of materials. Work hard. I believe that with your talents, one day you will make extremely dazzling achievements in materials science.

score."

Watching the old academician's car slowly driving away amid the falling yellow leaves, Ning Qingyun's eyes became moist: "Qin Xiaoke, we are so lucky to always meet such good elder teachers."

"Yeah..." Qin Ke was also full of emotion. He noticed that Academician Song Shiliang's eyes had bloodshot eyes after staying up late. He probably stayed up all night to come up with such a detailed answer because of this question he and Ning Qingjun had.

In order to tell them this answer clearly and unmistakably as soon as possible, I traveled more than ten kilometers by car.

You must know the traffic congestion in the capital. A drive of more than ten kilometers will take at least an hour, which is not an easy thing for Academician Song who is not in good health.

Probably the old academician wanted to repay the two for saving their lives...

For many simple older generations, the word "gratitude" does not need to be expressed in words, but only in actions.

Qin Ke took a breath and said: "Let's go visit Academician Xia Song on the weekend and teach him the Eastern Peiyuan Method."

…

Academician Song's answer gave Qin Ke a deeper understanding of the principles of crystal structure and the origin of structural changes. He had a lot of new ideas and simply discussed the "application of n-s equation in urban planning and air pollution prevention and control".

The paper was handed over to Ning Qingyun, and he immersed himself in researching superconducting material optimization solutions for topological quantum computing.

The quantum computing laboratory has been operating at full speed for more than two months now. Because there are enough experimental equipment and experimental personnel, new experimental data can be fed back every week.

What Qin Ke and Ning Qingyun have to do is to continuously optimize mathematical models based on experimental data on the energy, atomic force, bond length, superconductivity, superhardness, vibration spectrum, phase change and phase diagram of superconducting materials, and try their best to

The most accurate synthesis ratio and crystal structure of superconducting materials can be deduced as much as possible, reducing unnecessary detours.

Now there is only one step left to find the most ideal Majorana fermion carrier. Academician Song's professional answer makes Qin Ke's mind continue to flash sparks of inspiration.

He almost dove into the pile of papers, leaving behind the n-s equations and Hodge's conjecture, and devoted all his free time every day to this topic of topological quantum computing.

He still relies mainly on mathematics, coupled with his own knowledge of physics.

Although he has a systematic "Virtual Scientific Research Experiment Center" in which a complete quantum computing laboratory has been projected, including all equipment, allowing experimental operations to be performed in the virtual world, the topological quantum computing experiments involve many detailed steps.

It often takes twenty or thirty people to work together, and it takes about a week to complete an experiment correctly.

If Qin Ke is allowed to operate it alone, even if his movements can be as fast as his thinking speed, he can also adjust the time flow rate in the virtual laboratory at any time, but it is still very time-consuming and energy-consuming. He tried this during his "vacation" back to Yuanzhou

He conducted experiments in the virtual laboratory, and it took him ten days to complete it intermittently. The efficiency was so low that he could only treat it as a skilled operator of experimental equipment.

After that, Qin Ke continued to hand over the experiment to Harold, Ling Shaotang, Gan Peixuan and others. He only used his best mathematical modeling combined with physical knowledge to guide the experiment and improve the theoretical system of quantum computing.

Time flies very fast when you are busy.

It took Ning Qingyun about three days to complete a paper titled "Research on the Application of N-S Equation in Urban Planning and Air Pollution Prevention and Control". The first authors were naturally her and Qin Ke, and the second authors were all those who participated in the experiment.

member, and then submitted it to "Physics Reports", one of the four top physics journals.

"Physics Reports (PR)" is one of the most influential international review journals in physics and cross-science. It has a long-standing reputation in the international physics community, with an impact factor of 25.6. Its biggest feature is that it generally only publishes one article in each issue.

Papers, and the journal basically does not accept free submissions. Most of the manuscripts are written by the magazine editor after selecting the topic and inviting physicists who have made outstanding contributions in related fields.

Although "basically not" does not mean "never", PR has published only a handful of unsolicited papers in the past few decades.

Ning Qingyun didn't understand why Qin Ke still asked her to submit an article to PR even though she knew this situation. Since Qin Ke insisted, the girl still obediently submitted the article to PR's editor's mailbox - anyway, she was mentally prepared.

If the PR is really rejected, then she can switch to other journals, such as "Nature Physics". She has full confidence in the paper written by herself and Qin Ke. At least "Nature Physics" will definitely reject it.

of.

After completing the submission, Ning Qingyun also joined Qin Ke's research and buried his head in the pile of draft papers side by side with him.

Whenever they feel tired, the two of them look at each other, smile, and give each other high fives, which gives them new energy.

Before they knew it, late autumn was coming, and most of the leaves of the green plants in the yard of their big villa turned yellow. Even the leaves of the sycamore tree in the yard were almost gone. With the arrival of November 30, the chill of early winter filled the air.

the entire campus.

That night, the north wind was howling outside, bringing the first rain of winter. The nanny Qingsao and her daughter closed all the windows in the villa early. There was heating in the room, so it was very comfortable.

However, Qin Ke didn't even hear the "plop, plop, plop" sound of raindrops hitting the window. His mind was all on studying the most ideal Majorana fermion carrier.

Suddenly, a system prompt sounded in his ears, interrupting his thinking.

"Ding Dong! You have concentrated on studying difficult physics knowledge for more than 300 hours this month, and you will be rewarded with 30 academic points (physics)!"

It’s time to reward learning points at the end of each month!

Qin Ke looked at the big clock hanging in the study room. The hands had just passed 0:00 quietly, arriving on December 1st.

Another month has passed...

Qin Ke sighed inwardly and glanced at Ning Qingyun, who was also writing and calculating seriously and attentively next to him. Just as he was thinking about advising Xiao Baicai to rest early, the system prompt sounded again in his ears.

"Ding! Your academic points (physics) have accumulated to 1019, meeting the upgrade conditions!"

"Your physical level has been upgraded to: 'Master Level'!"

"Physical level: Master level, next level: Grandmaster level, upgrade progress: 1019/."
