However, there is no regret medicine in this world, if Wang Yinan had known that this was likely to be an alien civilization that focused on time streaming, then why would he have to get a few super high-precision signal receivers and put them on the Xianglong drone.

The analysis of the data has reached an impasse, and there is no way, so I have to improve the resolution of signal processing as much as possible under the premise of eliminating the impact of error and noise as much as possible.

When he saw this paper back then, Wang Yinan couldn't help but complain, "This must be a boring programmer, after getting some ***** from the Sun Country, he really can't stand the clumsy coding effect, and the technology specially developed."

However, this kind of technology is quite suitable for use in the current situation, Wang Yinan hurriedly found the paper on the Internet and studied it carefully, don't you say, for this topic, in addition to Mi Ge's original paper, there are more boring program apes who have a grudge against coding, and a series of follow-up studies have been carried out, and a lot of results have been obtained.

However, after studying the latest papers, Wang Yinan is still disappointed, the principles of these papers are based on a large amount of data, that is, a large number of uncoded videos are used to train the neural network, so that the original appearance of the coded video can be restored with high quality.

"Where can I find data from alien civilizations that have not been attenuated or polluted by noise to train neural networks", Wang Yinan sighed helplessly, and had to give up this idea that looked beautiful.

Wang Yinan called Chief Yang and told them his thoughts, hoping to help them in their analysis, and as expected, the team over there did not make much progress, except for a lot of "correct nonsense".

And there has been no news from Chen Zihao's side, if it weren't for Qian Zhonghua, there would have been no bad news, Wang Yinan wondered if this guy had been invited to tea by some powerful department in the rice country.

At noon that day, Wang Yinan had just finished a big class of "General Physics" at Imperial Capital University, which was an introductory physics course specially prepared for physics majors and non-physics majors.

Or another name, it may be more appropriate to call it "Physics in the Eyes of Wang Yinan", unlike the traditional physics education, which is organized with the four major mechanics as the backbone, that is, "theoretical mechanics", Newtonian mechanics in the traditional sense. "Electrodynamics", the electromagnetic theory with Maxwell's equations at its core, quantum mechanics, the essence of the world is waves and particles, "Statistical mechanics", if there are too many objects to study, try this thing.

For ordinary people, seeing a big boss like the four major mechanics must be blindfolded. Even if you are a particularly good student in high school physics, if you want to complete these four major mechanics in undergraduate science at once, you will definitely doubt life.

By the way, have you noticed that there is no "Special Relativity" here, this is basically a separate course for physics majors, and there is no "General Relativity", there are only three people who are said to understand this thing back then, and today, most of the professors in the serious physics department, as long as they are not specialized in general relativity or the theory of the universe, do not understand it.

After Wang Yinan finished learning the four major mechanics, he deeply felt that physics should not be cut apart by rigidity, and in terms of difficulty, there are particularly difficult parts in every discipline, such as the legendary three-body problem, which is completely in the category of theoretical mechanics, and does not involve quantum mechanics or relativity at all.

In his eyes, the basic components of the world are microscopic atoms, that is, the essence of this world is quantum mechanics, and the essence of light is electromagnetic waves, which everyone knows.

The interaction of light and other electromagnetic waves with atoms, or a large number of atomic structures (lattices), then constitutes the wonderful world before our eyes.

"Theoretical Mechanics", Wang Yinan just explained it as a mathematical abstraction, if you go deeper, such as orbit calculation, perturbation analysis, and even finite element analysis, it is mostly in the category of engineering.

And Wang Yinan faintly has some predictions that with the development of computing technology, especially the maturity of artificial intelligence neural networks, most of the content of theoretical mechanics will become a program library, and sooner or later, many skills will never appear in textbooks again.

The reorganized "General Physics" was very popular with students, and this way of abandoning many complicated theories and getting closer to the essence of nature was the favorite of students, and Wang Yinan did not choose the common Schrödinger wave equation when explaining quantum mechanics.

He chose Dirac's matrix mechanics, and when Wang Yinan made a set of playing cards with matrix operators by himself, and demonstrated in class how to use this deck of playing cards to infer the orbit of quantum transitions, as well as Pauli's incompatibility principle, the whole class was boiling, and many students found out for the first time that physics was still so interesting.

"Professor Wang, if you use mahjong tiles to represent matrix operators, where do you think the mahjong rules are most appropriate, is it Huadu Mahjong, Imperial Mahjong or Shudu Mahjong", after the lecture, a bold student asked his own question in the laughter of everyone.

Wang Yinan did not laugh at him, "This spirit of courage to think is still worthy of recognition", Wang Yinan said,

"I haven't really studied which style of play is more suitable, but I think I can analyze the basic structure, such as the number of types, the mapping of rules, and whether it can be exchanged."

After Wang Yinan's guidance, the student really spent a lot of effort to study the relationship between mahjong and matrix mechanics, and finally published several papers, "Using Mahjong Dynamics to Explain Pauli's Incompatibility Principle",

"Hommorphic Mapping of Winning Cards and Orbital Transitions",

The final conclusion is, forget it, I won't spoil it, let's read the paper for yourself in a few years.

After answering the question of this student who likes mahjong, of course, Wang Yinan finally asked him, "You are a student from the land of abundance, right?" As expected, an affirmative answer was obtained.

At this time, Wang Yinan's phone rang suddenly, and when he picked up the phone, Wang Yinan found that the caller ID was an unknown number, so it wouldn't be another harassing call, Wang Yinan thought, could it be Yang Lihan, there has been no news of this witch for a long time.

When I got on the phone, it was a very familiar voice,

"Boss, you've done my task",

After being stunned for a long time, Wang Yinan reacted that Chen Zihao's voice was on the other end of the phone, "What kind of fame, what phone do you use to call me, why don't you use your own phone",

"Didn't you say you wanted to be safe, I was afraid that if someone was targeted, I used an Internet phone to call you",

"Safe your size, this is in the imperial capital, in the imperial capital!" , Wang Yinan said,

"No matter how big the FBI is, how dare you come here to make trouble? Where are you, I have come to you",

"The old money will arrange the place, you wait, I'll ask them for the address here and send it to you, and hang up first," Chen Zihao said.

A few minutes later, a positioning address was sent to Wang Yinan's prestige, Wang Yinan drove according to the address for 30 minutes, and came to a small courtyard on the edge of the reservoir in the north, there were two armed policemen standing guard at the gate of the courtyard, which looked inconspicuous, but Wang Yinan's trained eyes found at least three secret posts on the commanding heights.

Brushing his face and entering the courtyard, Wang Yinan found that there was something different, many staff wearing white coats came and went, and a low buzzing sound could be heard in the whole courtyard, in a separate office, Wang Yinan saw Chen Zihao.

"Do you remember the electronic warfare unit that the military wanted me to go to?" said Mr. Chen.

"That's it, I found that they weren't useless, and there were a few guys who were of a good level."

Wang Yinan looked at the environment left and right, "Not bad, find a place for Qian Zhonghua by yourself?" ”，

"Yes, I told him that I wanted to get some information about Boston Dynamics, and his eyes turned green when he heard it, and he had to give me a small team, and also provided a field and a supercomputer, their computer is far worse than the Gödel system, but it is very easy to use to brute-force the password."

"You have to share what you get, don't want to take advantage of them when you cooperate with them", Wang Yinan knocked Chen Zihao's head angrily, "I will have more eyes in the future."

"Show me what you get," Wang Yinan said.

Chen Zihao called up several pieces of information on the oversized monitor, "I didn't try to hack into their control system, so in general it was relatively easy, and I didn't encounter a particularly strong tracking system."

"Look at this", Chen Zihao pointed to a structural diagram and said to Wang Yinan,

"This should be the blueprint of the latest robot."

Wang Yinan began to carefully study the design drawing, Chen Zihao's work is very authentic, he has almost all the references on the design drawing, almost all the references, so that as long as you click on the specific part, in most cases you can see the component description and detailed electrical parameters.

"The vast majority of them are still hydraulically driven", Wang Yinan shook his head, "It's still a very traditional drive method, I thought there was some black technology",

"It's true that most of them are hydraulically driven, but stepper motors are used in some small joints," says Chan.

"I'll take a look", Wang Yinan magnified the place pointed out by Chen Zihao, "It is indeed a stepper motor, but this place should be mainly used for auxiliary attitude control, and the damping is not too large, so the stepper motor is enough",

"Also, their hydraulic power unit indicators are not ordinary," Chen Zihao said.

Carefully checked the main power position, the hydraulic power of the connecting part of the feet and the torso, "Indeed, the requirements are not ordinary, the key is that its own weight is very light, have you asked the domestic situation, can our hydraulic power unit do this level?" Wang Yinan asked,

Chen Zihao pouted at the white coats who came in and out of the room next to him, "They sent someone to find out."

"The best level in China, to achieve the same performance indicators, at least more than double the weight."

"There is still a gap in basic industry", Wang Yinan couldn't help but sigh.

"But you mysteriously called me over, just to see these big road goods? , this is not like your style", Wang Yinan looked at Chen Zihao suspiciously, this kid looked at it like he had private goods.

"The boss still understands me", Chen Zihao touched his forehead embarrassedly, "Look at this", he clicked on a document,

"Artificial Muscle Power Device",

"This is what I found in a very hidden place on their server, it was third-party research, and it could well be the winner of their next-generation powerplant selection."
