Rebirth of science and technology academic master

Chapter 193 Minimal Model Program

Then, in the name of a visit, they had sex for two days. They felt refreshed. They hugged each other goodbye at the airport and took a plane respectively. Qin Yuanqing's plane was from Hengdian to Lin'an Airport and then stopped at Lin'an Airport to fly to Ludao Airport. .

Ludao Airport is very busy at this time, with a lot of passengers coming and going. As a flight center in southern Fujian, Ludao Airport has a lot of passenger traffic every day.

Qin Yuanqing met his eldest brother and found out that the second brother had gone home early. Qin Yuanqing bought some tea, tobacco and wine in Ludao and put them in the trunk, and then went back to his hometown without staying in Ludao for any longer.

When he was at the entrance of the village, Qin Yuanqing stopped the car, got out of the car and took a look at the construction site that was in full swing. The segmented construction, multiple construction machines and construction teams made the progress very fast, and the upper reaches of the bridge had already been completed.

Obviously, the construction unit must take advantage of the arrival of the flood season to hurry up and complete the project as soon as possible.

A very special thing about water conservancy projects is that they are very affected by floods. Once they enter the flood season, it will become troublesome. It is difficult to construct diversions. In the dry season, when the rivers are dry and there is no water, there is no need to construct diversions. , easy to construct and save construction costs.

The construction unit also directly recruits some simple construction workers nearby, bringing considerable employment opportunities to surrounding areas.

"Brother, how is this construction team? Will they cut corners?" Qin Yuanqing asked.

This is sometimes the case. The local villagers know better than anyone else how good the construction is. Whether there is anything fishy during the construction can never escape the villagers' sharp eyes.

"The response from the villagers has been good, there are no problems!" The elder brother said with a smile: "Everyone in the team attaches great importance to this project, and the construction workers don't dare to mess around!"

Projects worth hundreds of millions are very rare to see in counties, let alone rural areas, and Qin Yuanqing is a national celebrity. Once any construction quality problems arise, it will be embarrassing to the whole country, and even the world.

Qin Yuanqing nodded slightly.

The two drove back directly. Looking down from the upstairs of their home, you can see the construction site. In the future, the entire area will be built like a park. It can be said to be a large wetland landscape.

The planning of the entire area has been completed. The planning made by the courtyard is very grand. It not only considers a few villages, but also considers the entire eastern area, and the small areas within it are planned in very detail.

For example, there are building height limits in the area, such as drainage systems, controlled elevations of plots, types of seedlings, etc. The entire renderings appear at the village headquarters and town government of each village.

According to the area plan, villa areas, hotels, etc. will be set up around and within the area. The villa area is not a European-style villa, but a villa with a southern Fujian style. The entire area is based on the overall style of a southern Fujian water town.

Qin Yuanqing's return to his hometown suddenly aroused heated discussion in the village. After all, Qin Yuanqing did not come back for the second half of the year. He was also the biggest celebrity in the village. Everyone was related by relatives. The already lively family suddenly became The crowds made Qin Yuanqing helpless.

This is one of the reasons why Qin Yuanqing goes home less and less. He feels like an outlier in the village.

China is a humane society, and some things have already formed customs and habits. You can't talk too much to these. If you talk too much, people's faces will change and they will fall out with you. Then the whole village will spread that you are condescending and looking down on blind dates.

People's words are scary, that's why.

During the Spring Festival, we mainly visit relatives and friends, and then give red envelopes to every villager over 60 years old in the village. Each red envelope is worth 10,000 yuan. This red envelope is just right. It’s a little thoughtful but not too much.

After entering the third year of junior high school, the flavor of the Spring Festival began to fade away, and Qin Yuanqing also had some time to slowly solve the second problem of the minimal model program.

Compared with the first issue of the Minimal Model Programme, the paper on the second issue of the Minimal Model Programme is as long as 23 pages. The main content of the paper is to describe in detail the way to solve the second problem of the Minimal Model Programme. , that is, for algebraic varieties, the question of whether the flip operation will terminate after a finite number of times.

The final result is that this flip operation will indeed terminate after a limited number of operations.

Qin Yuanqing named the title of this paper "Proof that the algebraic variety Flip operation terminates after a finite number of times - a solution to the second problem of the minimal model program".

At this time, the Lantern Festival has just passed. It can be said that it does not even take a month to solve the first and second problems of the minimal model program, which is extremely funny.

However, solving the two problems of the minimal model program is only the key to solving the BAB conjecture. Next, we need to use this key to open the door to the BAB conjecture.

But he also had to embark on the road back to the capital. On the plane, Qin Yuanqing was also thinking about the final correct way to open the BAB conjecture.

In the paper on the second issue of the minimal model program, Qin Yuanqing proposed a concept called "standard bundle".

The standard bundle is a construction that lies at the heart of birational geometry. The standard bundle is defined at any point in a cluster. It encapsulates a large amount of geometric information about the cluster in a particularly useful way. By taking the parts of the standard bundle and raising them to exponential powers, you will get what is called a standard ring. geometric objects.

The standard ring can be used for the study of Fano clusters!

The BAB conjecture is to prove the boundedness of Fano clusters!

That’s why it is said that the minimal model program is the key to opening the door to BAB conjecture!

Without overcoming the minimal model program, it is almost impossible to unlock the BAB conjecture!

Now that Qin Yuanqing has conquered the minimal model program, it means that BAB guesses that this door is waiting for him to open it and see if the world behind this door is so exciting.

On February 14, Qin Yuanqing reluctantly left the institute. He had already started chewing the bones of BAB conjecture and entered the core area, but had to put it down temporarily.

Because the 2011 National Science and Technology Awards Conference has begun, as a banner-bearer of the young generation of Shuimu University and an important scientist, Qin Yuanqing must attend the conference, and Qin Yuanqing also participates in this conference.

Although he missed the National Natural Science Award, he could not escape the National Technological Invention Award and the National Science and Technology Progress Award. The question was only what level of the award.

In 2011, Qin Yuanqing had no scientific research results in the field of mathematics, but he achieved great results in engineering applications.

The winners of the top prize this year are Mr. Xie and Mr. Wu. Mr. Xie was born in 1920 and Mr. Wu was born in 1922. They are both 90 years old. This time they beat other candidates and were selected for the country's highest science award.

Everyone may only know that it is not easy for Mr. Qian to return to China. In fact, it was not easy for Mr. Xie to return to China. In 1951, he obtained a doctorate from Stanford University in the United States and resolutely chose to return to China to serve the motherland. As a result, he was blocked on his way back to China. It was not until 1955 that he overcame numerous obstacles. Return home. After returning to China, he worked successively at the Institute of Atomic Energy and the Institute of High Energy Physics of the Chinese Academy of Sciences. He served as deputy director of the Institute of High Energy Physics, chief designer of the "87 Project" accelerator, and project manager of the BJ Electron Positron Collider. He has successively won There are 11 awards including the National Science and Technology Progress Award Special Prize.

Mr. Wu is a meritorious figure belonging to Shuimu University. He is a Chinese architect, urban and rural planner and educator, and the founder of human settlement environment science. He assisted Liang Sicheng in establishing the Department of Architecture of Shuimu University. He has won the "World Habitat Award" successively. ", International Association of Architects' "Tschumi Award", "Asian Association of Architects Gold Medal", "Tan Kah Kee Science Award", "Ho Leung Ho Lee Award" and many honorary titles awarded by the United States, France, Russia and other countries.

This is an old man who always insists on combining theoretical research with practical work. He has a great reputation in the construction industry and urban and rural planning industry. He has disciples all over the world. He is regarded as the founder of modern times by countless cement workers and bricklayers.

Their awards are the country's greatest praise for their lifelong dedication to the country. They have lofty ideals, do not pursue material enjoyment, and do not shrink back at all when encountering difficulties. They always adhere to their original intentions and have no regrets.

In contrast, Qin Yuanqing is a vulgar person, a vulgar person who cannot tolerate vulgarity.

Looking at the two old men, Qin Yuanqing felt guilty and ashamed.

Although the old scientists of that generation did not have good material conditions, they had a firm heart and lofty beliefs. They pledged themselves to the country. Their only goal was to build China into a prosperous and powerful modern country and no longer be dominated by other countries. Bully.

It is because of their efforts that the country is what it is today, that it was able to defeat Asan in the first place, and that it was possible to beat South Vietnam, the world's third most powerful military country, to the ground.

Qin Yuanqing watched a video. It was about Mr. Qian's 96th birthday. A group of old friends came to wish him a birthday. When he saw an old lady in the crowd, Mr. Qian suddenly became very excited and asked her: "You How many children do you have now?" There was a long silence at the scene. Mr. Qian did not expect that she has been living alone for so many years. This stubborn old lady is called Li Pei! Known as the "Rose of the Chinese Academy of Sciences", when the death of her husband Guo Yonghuai shocked the world, she did not cry; later, when her only daughter died of cancer, she did not cry either. . . . . In her later years alone, she devoted her life to the country and lived in a small shabby building. In 2009, she donated her life savings of 600,000 yuan to the Guo Yonghuai Scholarship established by the Huaxia University of Science and Technology and the Chinese Academy of Sciences Research Institute.

It was the people of that generation who set an example and worked hard that built the backbone of China, allowing China to hold its head high and talk to Westerners. There is no longer a sign saying "Dogs and Chinese are not allowed" on the land of China.

Qin Yuanqing has great admiration for this generation of elderly people, because they have done the best that their generation can do. You can no longer ask them harshly. They give what they can to keep. They are all given to the descendants of China.

The donkeys of the production team also need to rest. When there are big recommendations, there will be another explosive update!
