This time, the news about the famine also attracted Ning Qingyun's attention. She asked Shiguang to search for related news, and found that the global rainfall in the past ten years has been less, and the temperature has been rising slowly. In addition,

The most direct result of overgrazing on grasslands is the expansion of desert areas, the retreat of green and the advancement of sand, which has also led to an increasingly serious food crisis.

If the main food crops had not been improved and their yields increased slightly, the scope of the famine would have expanded.

Preventing and controlling desertification, returning sand to greenery, and expanding food planting area have become urgent global strategic issues.

As a country with desert area accounting for nearly 27% of the land area, Xia's desertification problem is also prominent. Many people who have lived on the edge of the desert for generations have pitifully low annual incomes, even lower than farmers in some impoverished mountainous areas.

, how to turn waste into treasure and turn yellow sand into fertile soil for growing food will determine the future life of millions of people in desert areas.

"Qin Xiaoke, our 'Ling Lemon Student Aid Foundation' can consider joining the student aid project in rural areas on the edge of the desert. In addition, the most important thing is that we need to step up the research on the perfect desert sweet potato."

Ning Qingyun had the same urgent idea as Qin Ke.

Qin Ke naturally agreed very much: "Okay, about the scholarship foundation, I will call Sister Huo right away. As for stepping up the research on the perfect desert sweet potato, I completely agree. Anyway, the paper is finished, and our main energy can be

All of it is devoted to the research of the perfect desert sweet potato and the improvement of computational seed science.”

He raised his hand: "We have been studying this topic for more than two years in total. It has been delayed for too long. We will try to solve it within nearly a month! Jun'er, let's work hard!"

"Come on!" The palms of the big one and the small one clapped together, which also heralded the birth of their first great invention that would benefit the entire world!

…

Qin Ke's goal for the next month was not blindly confident. This assignment to the desert to conduct meteorological research gave Qin Ke and Ning Qingyun a deeper understanding of the desert. Ning Qingyun's Ph.D. thesis in physics was about desert sweet potatoes.

Soil drip irrigation technology is also helpful.

After nearly two years of continuous optimization and improvement, the computational seed science theory established by the two people has formed a mature theoretical system with "DNA data analysis as the basis, biological theory as the core, and mathematical modeling as the basis."

During this period, the Lime Plant Breeding Laboratory also produced many new research results.

The perfect desert sweet potato has actually seen the dawn of success.

In order to make the perfect desert sweet potato within a month, the two did not even invest much time in defending their doctoral thesis, and put aside the n-s equation for the time being. In addition to cooperating with Professor Koppet of Germany on "topological quantum computing" every week

In addition to three video conferences, the research team devoted all their free time to researching the perfect desert sweet potato, and the appointment was temporarily suspended.

Ning Qingyun is mainly responsible for theoretical improvement and optimization of mathematical modeling, while Qin Ke is responsible for DNA matching experiments and cross-breeding programs.

This division of labor was naturally proposed by Qin Ke. He has a "virtual scientific research and experimental center" that can verify the shortcomings and improvements of the cross-breeding program in a very short time. In the past six months, he has used the "virtual scientific research and experimental center"

With the time acceleration function in it, nearly 5,000 cross-breeding experiments have been completed.

If such an experiment were to be put into reality, even if there were sufficient manpower and experimental space, it would take about thirty years to complete such a large amount of "trial and error" work.

This is the result of Qin and Ke using "computational seed science" to establish a mathematical model and deduce the most likely correct direction, which reduces the workload of "trial and error".

Biological breeding, especially if you want to complete the cross-breeding of a nearly brand-new, super-high-quality species, it is also very difficult to maintain genetic stability and facilitate large-scale seed production.

However, as the "trial and error" work continues to advance, the research project on the perfect desert sweet potato is getting closer and closer to the end of success.

…

Time flies by like a white horse, and more than a week has passed in the blink of an eye in the busyness. The calendar turned to the page of June 30 amidst the scorching summer heat and the noisy chirping of cicadas.

On this day, Qin Ke and Ning Qingyun ushered in the last and most important moment of their student careers, the defense of their Ph.D. thesis in physics.

Both of their defenses lasted one hour, 30 minutes of which were their presentations, and the remaining 30 minutes were the question and answer session, which started at 9:30 in the morning.

At early eight o'clock, Qin Ke had packed up and put on a white shirt, suit and tie that he seldom wore. Naturally, Ning Qingyun had prepared this well-fitting "battle suit" for him.

Although Qin Ke's current status actually means that he doesn't have to look at other people's faces, and wearing a T-shirt casually can still reflect his personality, this PhD defense meeting is different. Not only Jiang Weixian, but also the chairman of the physics department and most of the physics professors will come

The judges were several senior physics academicians invited to watch. At such an important moment, dressing neatly is a sign of respect for the teacher and for the last important defense of one's student career.

Besides, after the defense there is a photo session, so you can’t dress so casually and make the teachers and seniors taking the photo feel uncomfortable, right?

He looked in the mirror and saw that there were still a few hairs on his head that were stuck out of place. Qin Ke ignored them. After meeting Xiao Baicai later, the attentive girl would definitely help him use styling spray to fix them - Qin Ke anyway.

I would never buy anything like this for dressing up.

"Wow, Brother Ke, you are so, very, handsome!" The little fat man Jiang Zhenjie made a fuss around Qin Ke with an exaggerated expression.

"Come on, Chinese, English and Japanese are all here, what do you want to do?" Qin Ke crossed his arms and looked at the exaggerated performance of Little Fatty Jiang with a smile.

Little Fatty Jiang said mischievously: "Brother Ke, after today, you will be considered a Ph.D. graduate, right?"

"If all goes well, yes."

"We haven't graduated from our junior year, and you and the academic committee are about to graduate with Ph.D.s. It's amazing. In three years from undergraduate to Ph.D., you two have probably broken the world record, right? You are worthy of being the squad leader and academic committee of our basic science class. You are awesome!"

Superb! Number one in the world!" Little Fatty Jiang had a smile on his face and pretended to come over and give Qin Ke a pat on the back.

Qin Ke looked at him sideways: "Come on, Lao Jiang, you said the same thing from last night to now. If you have any plans, tell me immediately. If someone else gets there first, don't blame me for not giving you a chance."

Jiang Xiaopang rubbed his hands and said sheepishly: "Brother Ke, I won't be a senior in college next semester. According to the conditions, I can apply for postgraduate study, but the supervisor has not yet been decided... After you graduate with a Ph.D., you should be able to be directly appointed as a professor.

Right? You have published papers on prl before, and the extreme weather prediction model at the beginning of last month shocked the world. With such a level, there is no reason why the school should not give you a position as a full professor in the physics department, right? You should stay in school.

?Can I reserve your postgraduate place in advance?”

It is inevitable to get the title of professor. The paper they submitted to "Nature Physics" "Research on Extreme Meteorological Disasters in Deserts Using Mathematical Models with N-S Equations as the Core" has passed the preliminary review and is entering the expert review process. It will be published only

As for the time issue, even without mentioning this, the academic achievements Jiang Xiaopang mentioned just now are enough to be considered a full professor.

Qin Ke was funny: "Even if we get the professor's appointment letter, it's hard to say whether the school will give us graduate tutor qualifications this year. And originally, according to my plan, we would not start tutoring graduate students until at least next year. This year, Qingyun and I

There are two topics at hand that need to be accelerated, and I may not be able to spare much time to teach graduate students."

Jiang Xiaopang hurriedly said: "Brother Ke, I will be a senior in September. I am not a first-year graduate student. It's just that the school requires me to select a supervisor in advance. As long as the supervisor agrees to accept me, I will start graduate school in September next year. The time is just right.

!”

Qin Ke nodded slightly. When he and Ning Qingyun graduated from their sophomore year, they went directly to graduate school with Academician Jiang Lao. They followed the special talent training route and had never gone through the ordinary path of postgraduate entrance examination. They did not expect that postgraduate entrance examination was

It started a year in advance.

Seeing that Qin Ke's attitude relaxed, Little Fatty Jiang put up two fingers on his stick and said: "Brother Ke, I know that Xiang Xue must have reserved one of your postgraduate positions in advance, so I won't compete with him for the top spot.

The position of the first disciple is up, but I have to be ranked second, and Xiaohua can only be ranked third! Just leave a spot for me and Xiaohua."

Qin Ke said angrily: "Stop it, stop it, the master's degree supervisor only takes care of three students in one term, do you think you have taken them all?"

Jiang Xiaopang said flatteringly: "The first one who is near the water tower gets the moon. They were too embarrassed to mention it, so they had to entrust me to mention it. Brother Ke, you are our boss, you can't abandon us who know everything, and free up this precious quota for

Other students?"

"If I remember correctly, Xiang Xue chose the direction of fluid mechanics, and he wanted to apply for my graduate degree. I can understand it, but Lao Jiang, you studied the direction of 'Energy and Power Engineering', right? And Manting's 'Microelectronics'

The direction of science and optical measurement is not what I am best at. Going to graduate school with me is not your best choice. If you want, I can recommend you to the Department of Physics of Qingmu University or the School of Physics of Yanda University next door.

And I can help you choose a more suitable graduate tutor. I can even help you if you want to study abroad."

In fact, if Qin Ke wants to accept Jiang Xiaopang and Hua Manting as graduate students, he can.

The full name of Jiang Weixian's experimental building is "Qingmu University Aerodynamics (Fluid Mechanics) Research Laboratory". Because Jiang Weixian has made the most remarkable achievements in fluid mechanics, outsiders are accustomed to calling it simply "Fluid Mechanics Laboratory".

In fact, it includes several research directions, such as physical materials, aerodynamics, and several subdivisions of fluid mechanics. Currently, Qin Ke is more exposed to the "Air Turbulence and Climate Prediction" research group, which is also the research group in the laboratory.

The core research group has 157 people, including five groups including the "turbulence group", which correspond to several major subdivisions of fluid mechanics.

There are indeed related research groups in the field of physical materials and aerodynamics, namely "Microelectronic Materials Research Group", "Physical Materials Preparation Research Group", "Aircraft Power Research Group", and "Electron Microscopy Research Group"

"However, the total number of people in these four research groups is only 70, which is less than half of the number of people in the "Air Turbulence and Climate Prediction" research group, and the importance is naturally lower.

If Jiang Xiaopang, Hua Manting and Qin Ke go to graduate school, they can only join the "Aircraft Dynamics Research Group" and "Electron Microscopy Research Group" respectively for exercise. This is not as good as the "Air Turbulence and Climate" that Li Xiangxue can enter.

"Forecasting" key research group.

Moreover, Qin Ke's current physics level is "professional level". Except for fluid mechanics, which can reach or even surpass the level of most professors, the other sub-disciplines are only equivalent to the level of a young lecturer with a PhD degree - even if he is confident that he can complete physics within one year.

The level is upgraded to "Master Level", but it also takes time to slowly absorb and digest the corresponding knowledge. Before fully integrating the "Master Level" physics subject knowledge, it will be difficult for him to give the best guidance to Jiang Zhenjie and Hua Manting.

With Jiang Zhenjie and Hua Manting's excellent undergraduate grade points ranking third and fourth in the department (second only to Qin Ke and Ning Qingyun), they can find better graduate tutors at home and abroad and enter better research groups.

.

Out of a responsible attitude toward his brothers, Qin Kecai made such a suggestion.

Jiang Xiaopang shook his head and said firmly: "Brother Ke, classmate Xiaohua and I just want to study with you in graduate school! To be honest, many tutors now regard students as free labor and do repetitive low-end experiments, which is difficult to learn.

What, if you piss off your tutor, it will be difficult for you to graduate. At least we feel most at ease following Brother Ke, and we trust your character from the bottom of our hearts."

Qin Ke was right to think about it. With his current reputation in the physics world, the physics professor at Qingmu University was okay, but Professor Daniel from the physics department of other schools might not give him face and take special care of his roommates.

Staying in the laboratory for a year or two doing low-end work such as cleaning, cleaning instruments, and recording data is a waste of Jiang Xiaopang and Hua Manting's talents.

He smiled and said: "Okay, let's leave it like this for the time being. We will see the actual situation when we actually go through the graduate school process. If I don't get the qualification to be a master's degree supervisor, everything will be empty talk."

Jiang Xiaopang was overjoyed: "Thank you, Brother Ke, then it's settled!"

"Okay, now that we've said it, you've delayed it long enough. Tell me, what surprise do you want to give me?" Qin Ke said with a smile.

"Wow, Brother Ke, you are really good at predicting things." Jiang Xiaopang's eyes widened in surprise: "How did you know we were going to give you a surprise?"

"It's past eight o'clock now, Xiang Xue and Man Ting are not here, and you keep stopping me to say this and that - you can say these things at any time, but if you leave it to now, you are delaying time. The final conclusion, you guys

You are doing something without telling me!"

Jiang Xiaopang pulled his hair in annoyance and said: "Brother Ke, you are so smart, has the school committee never been able to surprise you?"
