Chapter 159: Was this written by an undergraduate? Du Jin's parents could not resist their son's persuasion and returned to Rongde City. After returning to the school dormitory, Du Jin said hello to his roommates and briefly explained the reason why he had not returned for the past two or three days. Gu Zi went to bed. After all, the graduation season was coming soon. Everyone was considering their own future. Whether they were continuing their studies or striving to serve in the army, they all needed to have a very complete plan, so there were not many people. Ask Du Jin what.
Lying on the bed, Du Jin began to think about what technology he wanted to start with.
The "isolated" technology did not attract much attention, but for those popular subjects and research fields in Xia State, Du Jin was afraid of disturbing some people's cakes. After all, Wen Song's operation made him aware of these realities. factors and have a truly clear understanding.
"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 base, he just needs to reproduce or copy the scientific research of the blood-stamped world. of great men
"Picture book" can realize a technology that is far beyond reality, and Xiao Ai quickly responded: "Master, there are some gaps in the technical foundation and physical environment between the world we are in now and the blood-seal world. , if stable
Based on "regeneration", Xiaoai currently has dozens of climate models, carbon cycles, digital technologies, low-carbon heating and cooling, battery energy storage solutions, etc., which can be quickly industrialized and mass-produced according to blueprints and structural formulas, and the rest Technical Xiao Ai needs to modify and integrate according to the physical rules and logic of this world, which will take a long time. "The real world and the blood-seal world where Du Jin lives are said to be parallel worlds, but in fact they can be summarized as a kind of branched world. Is the measurement of physicists the only means that can cause the world to split?
of course not. Measurement is essentially the interaction between the measuring instrument and the superposition state. Other physical processes can also interact with the superposition state.
For example, cosmic rays can be in a superposition state propagating in all directions. If a ray traveling in one of these directions hits a crystal on a blue star, the ray will leave a trace on the crystal.
Crystals effectively measure the position of light. Because the light is in a superposition state of hitting the crystal and not hitting the crystal, the crystal enters a superposition state of leaving traces and leaving no traces.
In fact, and so does Everett's interpretation, reality splits. For example, Schrödinger proposed a famous thought experiment in which a cat in a box is in a superposition state 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 world the cat is dead .
When there are no observers, we can think of the world as splitting from the beginning.
"According to the many-worlds theory, this started with the Big Bang," Kent said.
"The universe may have started as a single quantum state, but it quickly became a superposition of many different descriptions of the universe. In some of these branches, the Earth would have formed. And in some of these branches, the Earth would not have formed. In In some branches of the Earth's formation, we will evolve, and in other branches, we will not evolve." Because people and things interact with countless particles all the time, decoherence effects will limit them to a single one. trajectories: they will not be in different positions at a certain moment.
If you are studying a microscopic object, such as an electron, then you can isolate it from the outside world well enough to observe the superposition phenomenon.
Of course, it is not to confirm the existence of the superposition state by directly observing it, but to let the superposition state exist independently, and then look for the physical phenomena that occur when the object is in the superposition state - this is how scientists can confirm its existence.
"But the larger the system, the harder it is to isolate it from the outside environment. So the larger the object, the harder it is to be in a superposition. This also means that 'all the different branches' are real," Kent said.
"There are many copies of you in these branches, and it makes no sense for you to ask which one is real. These copies are equal and they are all real. Until the world is divided, all copies have the same Memory. After a short period of time, there will be small differences between copies, and as time passes, the differences will become larger and larger." The many worlds idea may not be common sense, but its proponents praise it as both scientific and scientific. And elegant: it relies on the existing mathematics of quantum mechanics.
You don't have to introduce those mysterious
“something extra” to suddenly shift reality from a state of superposition to a state of certainty and singularity.
"There are no new hypotheses or new physical principles," Wallace said.
“That’s what we gain by taking existing theories seriously.” Not everyone is a believer in the many-worlds theory—and not because the theory seems crazy on its face.
After all, many theories seem crazy when they are first conceived. Today, no physicist would be deterred by this.
The reasons why people don’t believe in the many worlds theory are mainly divided into two aspects. Some people, including Kent, were not convinced that decoherence was enough to explain the division of the world into branches, and in each branch the world was as they saw it.
They worry that making decoherence theory a valid description of reality requires the introduction of additional assumptions, a fact that Du Jin, at least for now, is fully convinced of.
So Du Jin knew very well that since Xiao Ai thought that different physical environments could not be fully integrated in a short time, trying to forcefully apply them in the modern world would be counterproductive. A question about lithium batteries popped up in his mind. The idea of energy batteries, you must know, whether now or in the future net-zero world, low-carbon transportation and stable power supply require batteries that are more powerful, longer lasting, and faster to charge.
A sustainable future battery also requires 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 viable battery energy storage technology in the short term, and related research focuses on increasing energy density, reducing costs, extending life, improving charging safety and speed, and recycling and reusing batteries.
Longer term, researchers are exploring next-generation batteries using other materials and technologies to enable broader, 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 paid, new batteries with lower cost and higher energy density will be developed in the future. Now let alone Xia Guo, conventional lithium batteries have been put into various fields of society, but Du Jin is very clear that capacity, power, efficiency and size are still major difficulties. It just so happens that among the technologies that Xiao Ai can directly apply, especially The disguised lithium battery was within its range. Thinking of this, Du Jin stood up suddenly, picked up his clothes and phone and walked out of the dormitory. The remaining people in the dormitory looked at each other, Li Yang coughed lightly and said: "Cough Well, we still focus on how to prepare for the defense. Now that Lao Du has found a partner, he doesn’t need to worry about his grades. Well... it’s not bad to be a little more prosperous!"
"Damn! Didn't Lao Du betray the organization because he said he would not look for a partner in college but only love studying?"
"That's you. Look at how cowardly you are. You're about to graduate and you haven't really talked to more than twenty girls. How dare you say that?"
"Jia Xingnan, you have the nerve to tell me that you are so awesome but you haven't found a partner yet? Are you just like me? Why are you so arrogant?"
"I...I am addicted to studying and can't help myself. Falling in love can only slow down my efficiency in reading documents."
"Appeal........."...................... ................................................................. ....And Du Jin doesn’t know what’s going on in the dormitory
"Argument", he first came to the library, found paper and pen and copied the information Xiao Ai left in his mind. In fact, Xiao Ai could connect to Du Jin's mobile phone through the information and leave a complete and comprehensive data and industrial process structure, but Du Jin did not do so. The most important thing was to worry about leaks. According to what he had asked Xiao Ai before about why he needed to use his mobile phone to complete information reception and operation, Xiao Ai replied: "Master , the signal level that my current equipment is connected to is much higher than the current information technology in the world. I need to understand all the differences as much as possible. It will probably take a few days of adaptation time before I can adapt downward. Oh, it is not a small matter. Ai is lazy!!! ∑ノ" To put it simply, compared to the communication technology of the interstellar era, the current information technology is countless generations behind. Even the underlying infrastructure is different, and there is no way to be backward compatible. It is no less difficult than learning a language by yourself. After all, in terms of hundreds of years, backward technology will not necessarily appear in textbooks and libraries, but will be lost under the wheel of history. But in the face of this Even with a different structure, Xiao Ai can digest the technological crystallization of decades of human beings in just a few days. From this, we can see how powerful Xiao Ai is.
On the other hand, Du Jin clearly felt that he had a terrifying talent for understanding things, especially the ability to understand and remember various technical principles. He naturally knew that this was brought to him by the black blood seal.
"Talent", or ability, and as a person who likes scientific research, Du Jin, a result that far exceeds existing technology in all aspects is placed in front of him, but he hands it over without even looking at it. It is really too much.
It was a "waste", and if he didn't know anything about the technology he handed over, it would be a waste of money.
Afterwards, Du Jin started writing furiously in the library. Various numerical algorithms, theoretical systems and process structures were written down in his pen. Some theories that did not exist in reality for the time being, he could also ask Xiao Ai.
"Localized" replacement, time flies by, and the reading area in the library becomes increasingly empty. But fortunately, tomorrow is Saturday, and the library does not limit the use time of the reading area and rest area, but only closes the borrowing service. That’s all.
In a blink of an eye, it was already the next morning. When a large number of students poured into the library with various purposes such as studying, flirting, sleeping and passing time, Du Jincai looked at him with faint dark circles and faintness. The drowsy state passed by these students who were starting a new day. However, thinking of his brilliant opportunities next, Du Jin bit the tip of his tongue and forced himself to cheer up. He squeezed a thick stack of paper in his hand. Regarding the content, Du Jin played a little trick. He definitely did not write down the industrial preparation process and information. He only wrote down several laboratory preparation methods in detail, and these methods are the most time-consuming. And some that are not very efficient.
The information provided by Xiao Ai can be said to be so comprehensive that it provides dozens of laboratory preparation methods, which is just conducive to Du Jin's plan. He only needs to find out at the end of these data and information Note that there is a preparation method that is more efficient and has a higher success rate, but due to the limited experimental environment, its accuracy cannot be verified. As for the remaining associations, it is not Du Jin’s business to consider. Someone will take the initiative to do it for Du Jin. Jin started to think about it, and after spending nearly half an hour checking, Du Jin dialed Si Qing's phone number. As soon as Si Qing got through, he took the initiative to ask: "Xiao Jin, how are you now? There is no recurrence of any physical problems. Bar?"
"Si... uh, Xiao Qing, don't worry, I'm fine now. Do you still remember the agreement I made with you before? If you have time now, you can Can you come to school and meet me? Or you can meet me in another quieter and safer place."\"So mysterious?
Then I will pick you up now. Xiaojin, where are you exactly? \"Hearing Du Jin's solemn description, Si Qing immediately handed over part of the work to his subordinates, sealed the important documents, and then drove away from the army garrison. In her impression, every time Du Jin Being so solemn means that he has something extremely important. When she heard Du Jin take the initiative to go to a quieter and safer place, Si Qing became more and more curious about what Du Jin wanted to give to her. After getting in the car, he contacted the reception desk of a brigade under the control of his own forces. After all, in Xia State, the military was truly safe.
Arriving at the entrance of the National University of Science and Technology, Si Qing saw Du Jin holding a dark document bag in his hand. He didn't know whether it was the black blood mark that changed Du Jin's appearance, or the sensory effect of Si Qing who fell in love. She obviously felt that Du Jin was becoming 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 took out the contents inside. The paper materials were handed to Si Qing. Si Qing was originally just going to glance at it and pour water for Du Jin. Although she had high expectations and confidence in Du Jin's ability, in Si Qing's view, she really wanted to show up with the ability. To change the results of a certain branch of science, Du Jin's current foundation is still not enough.
It’s not that only those with academic qualifications are capable. The complexity of real society always exceeds our ability to generalize. After all, many of the older generation scientists in Xia State are not necessarily the so-called Ph.D.s or postdoctoral fellows, but their contributions are definitely undoubted. Yes, people's generalizations and summaries of laws have certain limitations. When encountering discussions that are not on the same level as themselves, people can always find some loopholes or counterexamples.
The reality is that the academic qualifications and abilities of different talents can be combined or separated from each other. It is not just
"Low education, high ability"
There are two either-or, binary opposition situations of "high academic qualifications but low ability", as well as
"Low education and low ability"
"High academic qualifications and high abilities"
"Medium academic qualifications and average abilities" etc., for college graduates
In the era of "exuberance", the last type of people may occupy a larger part of the talent market. From a conceptual and connotative perspective, it is difficult to measure who is more important, academic qualifications or ability.
The meaning of academic qualifications is very clear in our thinking: whether it is a junior college or a bachelor's degree, whether it is a master's degree or a doctorate, whether it is a prestigious school or a non-prestigious school.
However, when it comes to abilities, they are often empty, vague, and general words. It is difficult to give it a specific and clear definition. It includes not only learning ability, life ability, but also various abilities required for work. It can also refer to a person's overall quality.
Paradoxically, although some discourse arguments ultimately come down to
"Ability is more important", but in specific practice, people's behavior has made the opposite choice.
During the college entrance examination every year, we have long been accustomed to parents sending exams and the whole society to open convenient channels for the college entrance examination.
The "postgraduate entrance examination craze" is increasing year by year, and people who are already employed will resign and join the postgraduate entrance examination army... All these things seem to indicate that this is a
A society where “academic qualifications are more important”. In the final analysis, academic qualifications are explicit and abilities are implicit. Some abilities require self-discovery and experience over time at work; some abilities are innate and cannot be compensated for.
However, it is possible to improve academic qualifications through subjective efforts and hard study. When necessary, academic qualifications can even cover up the lack of certain abilities.
But Si Qing didn't have any thoughts of despising Du Jin. According to her expectation, no matter how good 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 relied on. results go stacking, otherwise age and
The cost of "relationships" is too disadvantageous for Du Jin. How could she not know about Du Jin's experience at 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. Originally, Si Qing was worried about how to find opportunities to publish a few articles for Du Jin.
"nominated" thesis, but she didn't expect that Du Jin would find a chance for her first.
"Hmm... Let me see, lithium-ion batteries are a hot field, but there are too many competitors in the field. If you want to make breakthrough discoveries... .......Wait, these data............." Turning to the second page of Du Jin's paper, Si Qing's eyes condensed, and she noticed something was wrong. It seemed that Du Jin had a deeper understanding of this aspect than she thought. The further she read, the more Si Qing understood. Du Jin moved a bird from the side. The chair was placed behind Si Qing. Si Qing was too involved and just sat down reflexively. Du Jin also knew very well that this paper could not be read in a few minutes, so he sat on the small sofa opposite and read. Seeing Si Qing's devoted look, Du Jin's heart slowly calmed down. The sleepiness and fatigue accumulated last night slowly came to mind, leading Du Jin to sleep.
"Xiao Jin? Xiao Jin?" Du Jin didn't know how long it had been before he woke up in a daze due to the call coming from his ears. Si Qing's slightly excited and surprised face immediately appeared in front of Du Jin's eyes. Needless to say, the refreshing effect of beautiful women is very obvious, not to mention a beauty like Si Qing who is his girlfriend. He blinked and responded lazily: "Xiao Qing, how are you? Have you finished reading?"
"Well.........I..." It was precisely because he had visited it from beginning to end, Si Qing She was so excited because she knew very well that if the data and methods in this paper were true, not to mention the explosive impact it would have on civilian applications, the military application could raise the energy efficiency of the entire Xia Army to a higher level. Of course, this is based on the realization of mass production. We must first have a basic prototype and then design, whether it is a device or an experiment, first miniaturize it and then increase productivity or efficiency, which is an improvement, and then it is a pilot test, which means to put the small The step of scaling up to a producible scale is actually the most important step in industrialization. Serious problems will often be encountered when scaling up things in a small scale. After pilot testing, is there trial operation?
In short, after passing, large-scale replication begins. Of course, production also has its own processes that take a long time, so a set of processes requires a lot of investment in manpower, material resources, financial resources, and time.
But this cost is countless times cheaper than stagnant development. Just talking about Xia Guo’s current unmanned early warning aircraft, the investment in battery life and equipment power consumption adjustment is already an astronomical figure. It costs manpower, time, The material resources are countless, but in terms of practical application, although it is not impossible to use, there is still a clear gap compared with the latest unmanned high-altitude early warning aircraft of country M.
And this is just one of the practical uses of Du Jin's paper. There are countless other places where it can be used, involving everything from mobile phone batteries to space stations. It is everywhere, so Si Qing couldn't help but Excited in her heart, she hesitated to wake up Du Jin, who was sleeping soundly, because she wanted to confirm the authenticity of the data.
