Chapter 159: This was written by an undergraduate? Du Jin's parents couldn't resist their son's persuasion, but went back to Rongde City, after returning to the school dormitory, Du Jin said hello to his roommates and explained a little about the reason why he didn't come back for two or three days, and went to bed by himself, after all, it was about to be the graduation season, and everyone was thinking about their future, whether it was to continue their studies and strive for a position in the army, they needed their own very perfect planning, so they didn't ask Du Jin anything.

Lying on the bed, Du Jin began to think about what technique he wanted to start with, too much

The "withdrawn" technology did not attract much attention, but for those popular disciplines and research fields in Xia Kingdom, Du Jin was afraid of moving some people's cakes, after all, Wen Song's operation gave him a truly sober understanding of these realistic factors.

"Xiao Ai, do you have any technology that has breakthrough value compared to the current era?" Fortunately, Du Jin does not need to start from his own knowledge, but only needs to reproduce or copy those scientific research greats in the blood-imprinted world

"Picture book" can realize a technology that is far beyond reality, and Xiao Ai quickly responded: "Master, there are some gaps between the technical foundation and physical environment of the world you are in now and the world of blood seals, if you stabilize it."

Based on "regeneration", at present, Xiaoai has dozens of climate models, carbon cycles, digital technologies, low-carbon heating and cooling, battery energy storage solutions, etc., which can be rapidly industrialized and mass-produced according to the blueprint and structural formula, and the rest of the technologies Xiaoai needs to be modified and integrated according to the physical rules and logic of this world, which will take a short time. "Du Jin's present world and the blood-stamped world are said to be parallel worlds, but in fact, they can be summarized as a kind of branch world, and the physicist's measurement is the only means that will cause the world to split?

Of course not. Measurement is essentially an interaction between the measuring instrument and the superimposed state, and other physical processes can also interact with the superimposed state.

For example, cosmic rays can be in a superposition of propagating states in all directions. If a ray traveling in one of these directions hits a crystal on a blue star, then the rays will leave a trail on the crystal.

Crystals are effective at measuring the position of light. Because the light rays are in a superposition of the crystals and those that do not, the crystals enter a superposition of traces and no traces.

In fact, the same is true of Everett's interpretation, where reality splits. Schrödinger, for example, famously proposed a thought experiment in which a cat in a box is in a superposition of life or death.

According to Everett's explanation, when you open the box and observe the state of the cat, the world has split into two branches: in one world the cat is alive and in the other the cat is dead.

When there are no observers, we can assume that the world has been dividing from the beginning.

"According to the many-worlds theory, this has been going on since the Big Bang," Kent said.

"The universe may have started as a single quantum state, but it soon became a superposition of many different descriptions of the universe. In these branches, the earth is formed. And in some of these branches, the earth does not form. In some branches of the formation of the earth, we will evolve, and in others, we will not evolve. "Since people and things interact with a myriad of particles all the time, the decoherence effect limits them to a single trajectory: they are not in different positions at a given moment.

If you're looking at a microscopic object, such as an electron, then you can isolate it from the outside world very well and observe superposition.

Of course, not by directly observing it to confirm the existence of a superposition, but by allowing the superposition to exist independently, and then looking for the physical phenomena that occur when an object is in a superposition state – this is exactly how scientists can confirm its existence.

"But the bigger the system, the harder it is to isolate it from the outside world. Therefore, the larger the object, the more difficult it is to be in a superposition state. "It also means that 'all the different branches' are real," Kent said.

"There are many copies of these branches from you, and it doesn't make sense for you to ask which one is true. These copies are equal to each other, they are all real. Until the world splits, all copies have the same memories. After a short period of time, there will be small differences between copies, and the differences will increase over time. "The idea of many worlds may not be in line with common sense, but its proponents praise it as both scientific and elegant: it relies on the existing mathematics of quantum mechanics.

You don't have to introduce those mysteries

"Something extra" to make reality suddenly change from a superimposed state to a definite, singular state.

"There are no new assumptions or new physical principles," Wallace said.

"That's exactly what we're getting by taking the existing theories seriously." Not everyone is a believer in the theory of many worlds – and it's not because the theory seems crazy on the surface.

After all, many theories seem crazy when they are first conceived. Today, not a single physicist will be deterred by this.

There are two main reasons why people do not believe in the theory of many worlds. Some, including Kent, are not convinced that decoherence is sufficient to explain that the world is divided into branches, and in each branch, the world is what they see it to be.

They feared that additional assumptions would be needed to make decoherence theory effectively describe reality, a fact that Du is fully convinced, at least for now.

Therefore, Du Jin is very clear that since Xiao Ai thinks that the different physical environments that cannot be fully integrated in a short period of time, it may be counterproductive to forcibly apply them in the present world, and an idea about lithium batteries immediately popped up in his mind, you know, whether it is now or in the future in the net zero world, low-carbon transportation and stable power supply require stronger, longer-lasting, and faster-charging batteries.

Sustainable batteries of the future also require the use of abundant materials and zero-carbon manufacturing processes. Batteries are the most efficient way to store renewable electricity, but current technological advances are not yet suitable for large-scale energy storage.

Lithium-ion batteries are the most feasible battery energy storage technology in the short term, and the research focuses on improving energy density, reducing costs, extending life, improving charging safety and speed, and recycling and reuse of batteries.

In the longer term, researchers are exploring next-generation batteries using other materials and technologies to enable broader, more economical electrification.

International cooperation and coordination should focus on identifying and testing new resource-rich materials to reduce costs, expand battery use, and minimize the environmental impact of battery production.

If enough attention is taken into account, new batteries with lower costs and higher energy density will be developed in the future. Now don't talk about Xia Guo, conventional lithium battery has been put into all areas of society, but Du Jin is very clear that capacity, power, efficiency and size are still a major difficulty, it just so happens that Xiao Ai's part of the technology that can be directly applied, the special lithium battery is within its range, thinking of this, Du Jin got up suddenly, picked up his clothes and phone and walked towards the outside of the dormitory, the rest of the dormitory looked at each other, Li Yang coughed lightly and said: "Ahem, we still pay attention to how to prepare for the defense, the old Du has found a partner, And there's no need to worry about grades, eh......... It's not impossible to be a little hot! ”

"Damn! Lao Du turned his back on the organization, didn't he say that a good university doesn't look for a partner and only loves to study? ”

"That's you, look at your cowardice, you're about to graduate, and there are no more than twenty girls who have really spoken, are you embarrassed to say?"

"Jia Xingnan, you're embarrassed to say me, why haven't you found a partner if you're amazing? Isn't it the same as me, arrogant what? ”

"I............ I am addicted to learning and can't extricate myself, and falling in love can only slow down my efficiency in reading literature. ”

"Call ..................." .................................................................................. And Du Jin didn't know what was in the dormitory

"Argue", he first came to the library, found a pen and paper to transcribe according to the information left by Xiao Ai in his mind, in fact, Xiao Ai can be connected to Du Jin's mobile phone through information, leaving a complete and comprehensive information and industrial process structure, but Du Jin did not do this, the most important thing is to worry about leakage, according to what he asked Xiao Ai before why he needed to use his mobile phone to complete the information reception and operation, and Xiao Ai recovered: "Master, The signal level of my current equipment docking is much higher than the current information technology in the world, I need to understand all the differences as much as possible, it will take about a few days to adapt, in order to adapt downward, but Xiao Ai is lazy!! ∑ノ"To put it simply, compared with the communication technology of the interstellar age, the information technology of the present world is not much behind, and even the underlying infrastructure is different, and it is no less difficult to be backward compatible than learning a language by yourself, after all, in terms of hundreds of years of dimension, backward technology will not necessarily appear in textbooks and libraries, but will be wiped out under the wheel of history, but in the face of this transformation that is not even the same architecture, Xiao Ai only needs a few days to digest the technological crystallization of decades of human beings in the world, it can be seen that Xiao Ai's ability is strong.

On the other hand, Du Jin obviously felt that he had a terrifying talent for understanding and remembering things, especially various technical principles, and he naturally knew that this was brought to him by the black blood mark

"Talent", or ability, and Du Jin, as a person who likes scientific research, has an achievement that far surpasses the existing technology in all aspects in front of his eyes, but he doesn't even look at it and hands it over, which is too much

"Destroying the heavens", and if he doesn't know anything about the technology he handed over, wouldn't it be the other way around.

Subsequently, Du Jin began to write hard in the library, and various digital algorithms, theoretical systems and process structures were written under his pen, and some theories that do not exist in reality for the time being can also be carried out by asking Xiao Ai

"Localized" substitution, time flies, and the location of the reading area in the library is getting more and more empty, but fortunately, tomorrow is Saturday, and the library does not limit the use of the reading area and rest area, but only closes the borrowing service.

In the blink of an eye, it was already the next morning, when a large wave of students poured into the library with various purposes such as studying, flirting with girls, sleeping and passing the time, Du Jin passed by these students who started a new day with a faint dark circle and a lethargic state, but thinking of his brilliant opportunity next, Du Jin bit the tip of his tongue and forcibly cheered up, he pinched the thick pile of paper in his hand, for the content, Du Jin played a little skill, and he must not have written in the process and information of industrial preparation, It is just that several methods prepared in the laboratory are written in detail, and these methods are the most time-consuming and inefficient.

The content of the information given by Xiao Ai can be said to be outrageously comprehensive, and dozens of laboratory preparation methods are given, which is just conducive to Du Jin's plan, he only needs to note at the end of these data and materials, there are more efficient and higher success rate preparation methods, but due to the limited test environment, it is impossible to verify its accuracy, as for the rest of the association, it is not for Du Jin to consider, someone will take the initiative to start brain supplementation for Du Jin, and after spending nearly half an hour checking, Du Jin dialed Si Qing's phoneAs soon as he got connected, Si Qing took the initiative to ask, "Xiaojin, how are you now?" There are no recurrences of any problems in the body, right? ”

"Division................ Uh, Xiaoqing, don't worry, I'm fine now, do you remember the agreement I made with you before? If you have time now, can you come to the school and meet with me? Or in a quieter, safer place. "So mysterious?

Then I'll pick you up now, where are you, Xiaojin? Hearing Du Jin's solemn description, Si Qing immediately handed over part of his work to his subordinates, sealed important documents, and then drove away from the stationing place of the unit, in her impression, every time Du Jin was so solemn, it meant that he had something very important, and she heard Du Jin take the initiative to say that he wanted to go to a quieter and safer place, Si Qing became more and more curious about what Du Jin wanted to hand over to him, and as soon as he got in the car, he contacted a brigade reception under the control of his own forces, after all, in Xia Guo, It is the inside of the military that can really be called security.

Coming to the door of the National Academy of Sciences, Si Qing saw Du Jin holding a dark document bag in his hand at a glance, I don't know if it was the black blood mark that changed Du Jin's external temperament, or the sensory effect of Si Qing who fell in love, she obviously felt that Du Jin became more and more chic, after Du Jin got in the car, she chatted all the way to the destination, after entering the reception room and closing the door, Du Jin opened the document bag in his hand and handed the paper materials inside to Si Qing, Si Qing was just going to scan it and then pour water for Du Jin, Although she has high expectations and confidence in Du Jin's ability, in Si Qing's opinion, if she really wants to have results that can change a certain branch of science, Du Jin's foundation is still not enough.

It's not that you have academic qualifications to have ability, the complexity of the real society is always beyond our ability to generalize, after all, many scientists of the older generation in Xia Guo are not necessarily the so-called doctors or postdocs, but their contributions are absolutely undoubted, people's generalization and summary of the law have certain limitations, and people can always find some loopholes or counterexamples when encountering discussions that are not at the same level as themselves.

The reality is that the academic qualifications and abilities of different talents can be combined or separated from each other, not only

"Low education and high ability"

"High education, low ability" these two either/or, binary opposition, and more

"Low education and low ability"

"High degree and high ability"

"Average academic qualifications, average ability", etc., among university graduates

In the era of "excess", the last type of person may occupy a larger part of the talent market. From the perspective of concept and connotation, it is difficult to measure who is more important, academic qualifications and ability.

The meaning of academic qualifications is very clear in our thinking: whether it is a junior college or a bachelor's degree, a master's degree or a doctorate, a prestigious school or a non-prestigious school.

However, when it comes to ability, it is often empty, vague, and general, and it is difficult to give it a specific and clear definition, which includes not only the ability to learn, the ability to live, but also the various abilities required for work, and can also refer to a person's comprehensive quality.

Paradoxically, although some discourse arguments will eventually fall

"Ability is more important", but in practice, people's behavior has made the opposite choice.

During the college entrance examination every year, we have long been accustomed to the parents sending the exam and the whole society opening a convenient channel for the college entrance examination

The "postgraduate entrance examination fever" is heating up year by year, and those who have already been employed will also resign and join the postgraduate entrance examination army...... All of this seems to indicate that this is one

A society where "academic qualifications are more important". In the final analysis, academic qualifications are explicit and abilities are implicit. Some abilities need to be discovered and honed by oneself through time at work; Some abilities are innate, and there is simply no way to make up for them.

However, it is achievable to improve one's academic qualifications through subjective effort and hard work. When necessary, academic qualifications can even mask a lack of certain abilities.

But Si Qing didn't have any thoughts of despising Du Jin in her heart, according to her expectations, no matter what the paper Du Jin gave him, she would use her own channels to publish it for Du Jin, after all, scientific research qualifications can only be accumulated by results, otherwise the age and

The cost of "relationship" is too disadvantageous for Du Jin, how could she not know what happened to Du Jin at the Wanglong Academy of Engineering Sciences?

But Si Qing didn't explicitly help Du Jin solve those problems, after all, she had to care about her partner's self-esteem, so she could only help Du Jin from the side

"named" thesis, but I didn't expect Du Jin to find her a chance first.

"Hmm............. I see, lithium-ion batteries are a hot field, but there are too many competitors in the field, and it is ................... to make breakthrough discoveries Wait, these data ...................." turned to the second page of Du Jin's paper, Si Qing's eyes stared, she noticed that something was wrong, it seems that Du Jin's understanding of this aspect is much deeper than she imagined, the more she turns Si Qing back, the more penetrated she becomes, Du Jin moved a chair from the side and put it behind Si Qing, Si Qing was too involved, just sat down reactively, and Du Jin also knew very well that this paper could not be read in a few minutes, so he did it on the small sofa opposite, Looking at Si Qing's dedication, Du Jin's heart slowly calmed down, and the fatigue and fatigue accumulated last night slowly came to his heart, and he took Du Jin to sleep.

"Nishiki? Nishiki? Du Jin didn't know how long it took, the call in his ears made him wake up in a daze, Si Qing's slightly excited and surprised face immediately appeared in front of Du Jin's eyes, I have to say that the refreshing effect of the beauty is very obvious, not to mention a beautiful woman like Si Qing as his girlfriend, he blinked his eyes and responded with a little laziness: "Xiaoqing, how is it?" Have you finished reading it? ”

"Hmm................. I ................ "It is precisely because of the tour from beginning to end that Si Qing is so excited, she knows very well that if the data and methods on this paper are true, not to mention the explosive impact on the civilian side, the application in the military can improve the energy efficiency of the entire Xia army by a level, of course, this is on the basis of mass production, first have a basic prototype and then design, Whether the device is a small experiment, it is realized first, and then the yield is improved, and then the pilot test is the scale, which means that the small-scale scale is scaled up to the scale of production, this step is actually the most important step in industrialization, often in the small scale of the scope of things will encounter serious problems, after the pilot is the trial operation?

In short, after passing, it is necessary to start large-scale replication, of course, production also has its process, which takes a long time, so a set of processes requires a lot of manpower, material resources, financial resources, and time investment.

But this cost is countless times cheaper than the stagnant development, just say that Xia Guo's current unmanned early warning aircraft, in the endurance and equipment power consumption adjustment of this investment, is already an astronomical amount, the cost of manpower, time, material resources is countless, but in practical application, although it is not unusable, but compared with the latest unmanned high-altitude early warning aircraft in country M, there is still an obvious gap.

And this is just one of the practical uses of Du Jin's paper, and there are countless other places that can be used, involving all aspects, from mobile phone batteries to space stations, everywhere, so Si Qing couldn't help but feel excited in her heart, and hesitated to wake up Du Jin, who was sleeping, because she wanted to confirm the authenticity of these data.
