Reborn Technology Scholar

Qin Yuanqing hesitated for a moment.

Do you want to redeem the space shuttle technology?

After careful consideration, Qin Yuanqing chose not to exchange 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 projects, it will not be too late to exchange for space shuttles.

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 deceived Perelman into going 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 thought for a moment and wrote down a few formulas on the draft paper.

"The Riemann Hypothesis is a conjecture proposed for the purpose of studying the π(x) function. Riemann's pioneering work was not to propose the Riemann Hypothesis, but to introduce the Riemann zeta function into the equation about π(x).

The 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/lnto(x^(1/2ε))...

"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 is no mathematical problem that he cannot solve.

Unless this math problem exceeds his level 15 difficulty level.

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 good 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 Yuan smiled lightly: "The key to solving the problem should be π (

x) function itself!"

Qin Yuanqing stopped writing and did not continue. After all, the Riemann Hypothesis was something he and Perelman had to work together to conquer, not him alone. If he had done it alone, Perelman would probably feel that he had no chance.

It worked and left directly.

And you can’t write too much. If you write too much, Perelman will probably be able to easily finish 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 lived a single life with a beautiful wife, but the beautiful wife was not around. Qin Yuanqing sometimes felt that the two of them were together every day.

Sleeping with your arms in your arms is the truly wonderful life.

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 in an autonomous guidance and control mode, and then made contact with the ring. After successfully completing a series of technical actions according to the procedures

Finally, 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 rendezvous and docking of this kind of aircraft is very high and it is a delicate job. Except for the United States, Russia and China, other countries have continuously mastered it.

Don't even dare to try.

Qin Yuanqing recognized this very much. Not all countries can engage in aerospace engineering. Look at the world today, where the United States, Russia, and China are doing very well. Other countries, even those 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 just started, but China was greedy and reluctantly took precious foreign exchange to participate. As a result, the money was paid, but the threshold was not

They didn't even step forward. People looked down on China at all and forced China to develop its own Beidou navigation system. The Galileo system initially launched cost about US$2.7 billion according to the planned Galileo plan. The system consists of 30 satellites, of which 27

The satellites are working satellites and 3 are replacement satellites. The satellite altitude is 24,126 kilometers and they are located in 3 orbital planes with an inclination angle of 56 degrees. In addition to 30 medium-altitude circular orbit satellites, the system also has 2 ground control centers.

But looking at it now, China has already completed the Beidou navigation system and provides global services, competing with the GPS navigation of 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 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 in the world has reached 100 billion US dollars. China’s Beidou navigation system has not only ended the annual income of American GPS from China

The "big cake" worth tens of billions currently generates an annual output value of 300 billion yuan. Although the proportion is not as high as that of GPS, the growth rate is very fast.

Europe, if we talk about the navigation system or the Galileo global navigation system, can barely handle it. As for other things, it is 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 in the west today, and you are actually 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 already vaguely understood that he seemed to have been deceived by this bastard Qin Yuanqing.

Qin Yuanqing rarely came to the Institute for Advanced Study, but was at 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, nor would he need to teach students. He would only need to take care of a doctoral student, and then the others would devote themselves to 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 Shuimu Institute for Advanced Study, but also has the title of director of the 'Perelman Mathematics Research Center'. And not surprisingly, this year he is an academician of the two academies.

Once elected, Perelman will also be elected as a foreign academician of the Chinese Academy of Sciences.

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

Foreign academicians are not a rare thing at all. They are not only found in China, but also in other countries. Many academicians from China are also foreign academicians from other countries, or academicians from the Third World.

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 die-hard towards 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 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 his status does not make this statement sound incredible, 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 his ability to express himself.

Satisfied: "I have written down these formulas. As long as I continue along this path, although I am not guaranteed to solve the Riemann Hypothesis, I should be able to solve the quasi-Riemann Hypothesis! This is a crucial step towards the Riemann Hypothesis.
