Rebirth of science and technology academic master

Qin Yuanqing hesitated.

Do you want to redeem the space shuttle technology? ?

After careful consideration, Qin Yuanqing chose not to redeem the space shuttle technology for the time being, because the reason is very simple. China is now mainly improving its internal strength, optimizing and transforming its industrial structure, and improving its military's combat effectiveness.

As for the aerospace engineering, we are currently building a unique space station for China. This is completely possible with the aerospace technology currently mastered by China, and the cost is relatively small, but it can achieve the same effect.

After four or five years, when China's overall situation improves and it has other energy to invest more in aerospace engineering, it will not be too late to redeem the space shuttle.

Qin Yuanqing went to the study and took out the draft paper. During this period, he had no time to devote to mathematical research, so he lured Perelman to China. As a result, only Perelman was devoted to studying the Riemann Hypothesis, and even brought a Ph.D. born.

It's really sinful when you think about it.

If Perelman found out that he was deceiving him, then Perelman, a math geek, would probably come to him for a duel.

Qin Yuanqing pondered for a moment and wrote down a few formulas on the draft paper.

"The Riemann Hypothesis is a conjecture proposed to study the π(x) function. Riemann's pioneering work was not to propose the Riemann Hypothesis, but to introduce the Riemann zeta function to convert the π(x) Research has been upgraded from real straight lines to complex planes." Qin Yuanqing looked at the first line of calculations he wrote - π(x)=∫dt/lnt+O(x^(1/2+ε))...

"The equivalence problem of Riemann's hypothesis." He stopped the pen in his hand and tapped the paper with the tip of his pen. Qin Yuanqing's expression gradually showed a pensive solemnity. With his current mathematics level, once he really wants to solve it, There's no math problem he can't solve.

Unless this math problem exceeds his level 15 level difficulty.

But you must know that it has been more than a hundred years since Riemann proposed the Riemann Hypothesis in 1859. Qin Yuanqing did not believe that Riemann was so awesome and that the conjecture he proposed could really stump him.

"If the Riemann Hypothesis is true, the asymptotic formula is also true, and in turn, the Riemann Hypothesis can also be derived from this asymptotic formula." Qin Yuanqing smiled lightly: "The key to solving the problem should be the π(x) function itself! "

Qin Yuanqing stopped writing and did not continue. After all, the Riemann Hypothesis was something he and Perelman wanted to work together to conquer, not him alone. If he did it all by himself, Perelman would probably feel that he was useless and leave directly.

And you can’t write too much. If you write too much, Perelman will probably be able to easily complete the rest. In this case, Perelman’s role will be less.

"These things should be able to keep Perelman busy for about a year." Qin Yuanqing muttered, folded the paper full of formulas, and put it into his briefcase.

After checking the time, it was getting late, so Qin Yuanqing turned off the light in the study and went back to the bedroom to sleep.

Lying alone on the bed, Qin Yuanqing felt that he was quite pitiful. He was obviously not single, but he still lived a single life with a beautiful wife, but the beautiful wife was not around. Qin Yuanqing sometimes feels that a truly beautiful life is when two people are together every day and sleep together.

Sighing, Qin Yuanqing let his head empty and fell into sleep.

The next day, Tianzhou-1 officially carried out rendezvous and docking with the Tiangong-2 space laboratory, gradually approached the Tiangong-2 laboratory through autonomous guidance and control, and then made ring contact. After successfully completing a series of technical actions according to the procedure, the docking mechanism is locked and the two aircraft are rigidly connected to form a combination.

Relevant experts are giving explanations and highly praise the success of this rendezvous and docking. After all, the technical content of this kind of rendezvous and docking of aircraft is very high and it is a delicate job. Except for the United States, Russia and China, other countries dare not even try it.

Qin Yuanqing recognized this very much. Not all countries can participate in aerospace engineering. Looking at the world today, only the United States, Russia, and China are prospering. Other countries, even known as Western developed countries, are in the aerospace industry. Engineering can't afford it either.

For example, Europe once launched the Galileo system as a civilian global satellite navigation system to compete with the GPS of the United States. At that time, the plan was just beginning, but China was greedy and reluctantly took precious foreign exchange to participate. As a result, the money was paid, but the threshold was not Even Mai didn't even take a step forward. People looked down upon Huaxia at all and forced Huaxia to develop its own Beidou navigation system. The Galileo system initially launched cost approximately US$2.7 billion according to the planned Galileo plan. The system consists of 30 satellites, of which 27 satellites are working satellites and 3 are replacement satellites. The satellite altitude is 24,126 kilometers and is located at 3 inclination angles. In the 56-degree orbital plane, in addition to 30 medium-altitude circular orbit satellites, the system also has 2 ground control centers.

But looking at it now, China has completed the Beidou navigation system and provides global services. It is not far behind the GPS navigation in the United States. However, the European Galileo system has not yet been fully networked, and the services provided are mainly concentrated in Europe. Europe cannot compare with the GPS navigation system and Beidou navigation system.

At present, the output value of Galileo navigation products and services in Europe has just reached 10 billion euros, and the output value of GPS satellite navigation products and services worldwide has reached 100 billion U.S. dollars. China’s Beidou navigation system has not only ended the American GPS’s annual revenue from China The "big cake" worth tens of billions currently creates an annual output value of 300 billion yuan. Although the proportion is not as good as GPS, the growth rate is very fast.

In Europe, if the navigation system is still the Galileo global navigation system, it can barely handle it. As for the others, they are far behind. Whether it is the number of satellites launched or the manned space project, they all rely on the power of the United States and Russia.

Russia's aerospace power mainly inherited the legacy of the Soviet Union. Although it has developed in recent years, it has not made much progress, and it has not even built new spacecraft.

As for Japan, Goguryeo, and India, each of these countries, which are known as the second most powerful countries in the world, have constantly proposed their own ambitious space programs. Unfortunately, they have encountered bumps and bumps along the way, and their development has been extremely unsatisfactory.

Qin Yuanqing also had to praise China's aerospace engineering. He relied on his own efforts to carry out the aerospace engineering with minimal expenditure, and achieved impressive results and fruitful results. This is definitely something to be proud of.

In the afternoon, Qin Yuanqing went to the Institute for Advanced Study and met with Perelman.

"Hi, Qin, the sun is rising from the west today, and you are here at the institute!" Perelman greeted Qin Yuanqing when he saw him.

During the time he joined the Shuimu Institute for Advanced Study, Perelman had vaguely understood that he seemed to have been deceived by Qin Yuanqing, a bastard.

Qin Yuanqing rarely came to the Institute of Advanced Studies at all, but was in the Automobile Research Institute, the Aero Engine Research Institute and the laboratory.

Institute for Advanced Study, Qin Yuanqing does not necessarily go to the Institute for Advanced Study once a month.

If it weren't for the environment here, Perelman would be very satisfied. He wouldn't have to worry about interviews with reporters or teach students. He would only need to take care of a doctoral student, and then the others would concentrate on studying mathematics and enjoy mathematics. In the ocean.

There are several mathematicians in Shuimu who are quite good. Sometimes when they discuss something, it often makes his blood boil, as if he has found the purity he had when he was a visiting scholar everywhere.

Perelman not only speaks Russian, he also speaks English, otherwise he would not have gone to Princeton as a visiting scholar.

"Perelman, I have a new idea on the Riemann Hypothesis, and I can't wait to share it with you. Look, how nice I am to you!" Qin Yuanqing said with a smile.

After all, Perelman is a math tycoon, so he is not only a professor at the Mizuki Institute for Advanced Study, but also has the title of director of the Perelman Mathematics Research Center. And if nothing else goes wrong, Perelman will also be elected as a foreign academician of the Chinese Academy of Sciences this year.

This is respect for talents. Not only should they be given generous salaries, but they should also be given sufficient honors.

Foreign academicians, this is not a rare thing at all. It is not only found in China, but also in other countries. Many Chinese academicians are also foreign academicians from other countries or third world academicians.

Of course, being able to become a foreign academician of the Chinese Academy of Sciences basically means having a friendly attitude towards China, rather than being a diehard against China.

"Oh? Qin, are you really studying the Riemann Hypothesis?" Perelman looked surprised. In the past few days, he had been thinking that Qin Yuanqing came up with the Riemann Hypothesis in order to attract him to Shuimu University.

"Of course, don't you believe in my character?" Qin Yuanqing took it as a matter of course, and then took out the draft paper where he wrote down the lines of formulas yesterday from his briefcase. It was only one page, but it was very precious. Qin Yuanqing said: " According to my research, more interesting conclusions may be obtained by advancing the lower bound estimate of the proportion of zero points on the critical line, but it is unrealistic to solve the Riemann Hypothesis itself through this method."

After hearing Qin Yuanqing's words, Perelman's expression gradually became serious.

The method of advancing the lower bound estimation of the proportion of zero points on the critical line can be said to be one of the mainstream methods currently used to study the Riemann Hypothesis, and the current "best" results of the Riemann Hypothesis are proved through this method. of.

However, Qin Yuanqing now said that this route may not work. Although this sentence does not sound incredible given his status, it still surprised Perelman.

"Qin, what do you mean?" Perelman looked at Qin Yuanqing.

"Maybe we have to return to the π(x) function itself." Qin Yuanqing talked eloquently, which made Perelman stunned for a while. Qin Yuanqing secretly expressed satisfaction with his ability to express himself: "These few I have written down the formula. As long as we follow this path, although we are not guaranteed to solve the Riemann Hypothesis, we should be able to solve the quasi-Riemann Hypothesis! It is a crucial step to take the Riemann Hypothesis."
