Hammer of Technology

Jiang Chenshuang lowered his head and smiled, but remained silent.

Well, the trick of keeping silent is quite useful, or I can only go back to peek at March's WeChat at night.

"By the way, have you ever thought about what you want to do in the future? Be a great mathematician after graduating from a doctoral degree?" Student Jiang changed the subject.

"Tell me about you first, why do you like playing the piano so much?" Ning Wei asked back.

"This..."

Jiang Chenshuang paused for a moment, and then answered calmly: "It was my second year of junior high school, before my father passed away, he took me to a relative's house in the city as a guest, the adults chatted there, and I sat there with my sister Watching TV, the movie "Sea Pianist" was playing on TV. At that time, I really felt that the appearance of 1900 playing the piano on the ship was very charming, and I was full of curiosity about the piano. At that time, I wanted to wait until I went to university. You must learn to play the piano."

After hearing this, I would rather be silent.

He forgot who once said a word, sometimes going to see an excellent movie can even change a person's fate.Ning Wei remembered that when he saw this sentence, he still scoffed at it, always thinking that it was a film practitioner fooling the box office, but now that he heard what Jiang said, he actually believed it a little bit.

Ning Wei asked, "I haven't seen many movies, so let's rewatch them when we have a chance. And what is 1900?"

Jiang Chenshuang tilted his head and glanced at Ning Wei, and explained: "1900 is the name of the protagonist in the movie, the pianist at sea who taught himself without a teacher. Because he was an orphan and was raised by a black man, so the year he was born Years became his name. It's your turn, what are you going to do in the future?"

"It should be a scientist. Studying mathematics is just the foundation. Isn't it interesting to use mathematical tools to do more interesting things, such as March?" Ning Wei replied.

Jiang Chenshuang nodded, and sighed, "San Yue is much smarter than the smart speakers of roommates in the dormitory, and much smarter than the Siri of their Apple phones. Although I don't know much about artificial intelligence, if it is released in March, it will definitely make people feel better. The whole world is shocked by it, right?"

"hey-hey!"

Speaking of March, Ning Weike was proud and replied: "That's for sure. When March was created, I told Brother Yu that March may be the originator of real artificial intelligence in the future, but now It’s still only a semi-finished product at this stage, and I don’t plan to promote it. So don’t promote it for the time being, and wait until the technology is fully mature in March in a few years.”

"But so many people know about it? For example, your roommate, and Senior Brother Yu." Jiang Chenshuang asked suspiciously.

Ning Wei smiled and said: "Haha, my roommates are not afraid when they know about it, even if they tell them everywhere, no one will believe them, they will only think they are bragging. And March used my WeChat to chat with them, As long as I don't admit it, no one will believe it."

"As for you and Brother Yu, you are definitely not as big-mouthed as the three of them, and you won't talk about it everywhere. The important thing is to let Sanyue get in touch with them, which can effectively exercise Sanyue's learning and thinking skills, which is very important for Sanyue's growth. It's also very important to say. By the way, let me ask you again, last time you said that your sister is still in high school, how high is this year? Which school are you going to take?"

Jiang Chenshuang replied: "Chenlu is in her third year of high school this year. She has better grades than me, is more self-reliant than me, and is much more sensible than me. I used to be ranked in the top ten in my grade, but she was always in the top three. Last time I talked to her once, and she hopes to get admitted to the school next door to study engineering, but I don’t know if the school next door will have a special recruitment policy when she takes the college entrance examination next year.”

"Girls majoring in engineering?" Ning Wei asked in surprise.

"Well, she said that the teacher told her that it would be easier for girls to get a job after studying certain engineering majors, such as numerical control, machinery, computer, and electromechanical. The employment options for undergraduates majoring in liberal arts, management, and pure science are too narrow." Jiang Chenshuang pointed nodded.

Well, Ning Wei felt that he had nothing to say. His thinking was much more pragmatic than his. When he applied for the major, he never thought about employment at all.Thinking that when he first entered Jiangda University, he felt that 1000 yuan was not enough for living expenses, which was a bit hypocritical...

Ning Wei gave a different opinion: "Ahem, actually I think you two are pushing yourself too hard. And the university next door is not very serious, at least our Yanbei University is more inclusive, unlike the next door, What vegetarianism, what small-eyed aesthetics, don't lead my sister astray. And our school's computer major is also okay."

"Ah?" Jiang Chenshuang was a little taken aback. It was probably the first time someone around her had heard such an evaluation of the university next door. She smiled wryly and said, "Let's not talk about her. I don't know if I can pass the exam."

"Can't pass the exam? How could you not pass the exam? Don't you rely on self-study in the third year of high school? Tell me which subjects she applied for. Later, I will ask someone to get some systematic review materials and exercise sets specifically for the college entrance examination. You can give it to her." After mailing it, all the questions that I don’t know will be ticked off, and I will find someone to give her a remote lecture at a fixed time. She is now in the top three of her grade, and she has been intensively trained for one year. It will definitely not be a big problem to get into Yanbei University.” Ning Weipo Said confidently.

Ning Wei's self-confidence certainly has a reason.

Although Jiang Chenshuang came to Yanbei University through special recruitment, but after coming to Yanbei University, she was able to get from the bottom of the class in the college entrance examination within one year, keep up with the progress and reach the middle level of the class, and it took a year to force herself Relying on self-study, being able to play the piano very well, in addition to being willing to learn and endure hardships, it also shows that the family's IQ is absolutely no problem, serious, willing to learn, and IQ up to the standard, this has reached the standard of talents, what is lacking is nothing more than famous teachers and better ones Just the way of education.

Ning Wei felt that he could indeed make up for this shortcoming.

Although he doesn't know this kind of person who is proficient in high school education, too many people around him are from the education system.Senior Brother Lu, Director Tian, ​​and a group of professors from Jiang University, Dean Kong, Academician Lu... Although asking these people for help may be suspected of killing mosquitoes with cannons, it doesn't matter to Ning Wei, anyway, he feels that he There is nothing to ask these big guys.

If it doesn't work, there is Brother Yu, a doctor. In short, there are many people who can help in education.

"Then let me thank you for Chen Lu first."

"By the way, how much is your sister's monthly living expenses? Can the nutrition keep up? High-intensity study requires high nutrition."

"I'm sure I can keep up. I just remitted 2000 yuan to her, which is enough."

Ning Wei nodded. Senior Brother Lu mentioned to him that Chen Shuang had also settled 6300 salary two days ago.

Just like this, the two walked and chatted, and when they returned to the research institute, Ning Wei was stunned when he entered the office.

A desk was changed in the office, and his belongings were all gone. Yu Xingwei was sitting upright on his seat, and Senior Brother Lu was reading a book in front of his seat.

Hearing the noise, Yu Xingwei turned his head and explained with a smile on his face: "Mr. Xiaoning is back, Professor Lu and I think it is not suitable for you to continue to squeeze into the same office with us, so just now you are not here. The location of the research has changed."

"Where did it go?" Ning Wei Erzhang asked confusedly.

"Next door!"

"Next door? How can there be..." Ning Wei quickly realized that Jiang had already walked into the specially vacated piano room, but there was no sound of the piano for a long time, and he was probably wondering.

"Ahem, needless to say, you must have thought of such an insidious move. Senior Brother Lu is not so fancy." Ning Wei glared at Yu Xingwei, then turned around happily and left the door.

At a certain time, appreciating a beautiful woman playing the piano is definitely more beautiful than being locked in a room with two big men, and this is not what he asked for. Straightforward.

Sure enough, when he walked into the next room, Jiang Chenshuang was staring at the extra desk and cabinet in a daze.

"Well, as you know, the two people next door felt that it was too crowded for three people to work in one room, and sometimes it was inconvenient to have a visitor or something, so they moved my desk here on their own initiative. It's all Brother Yu's bad idea, I have already severely criticized him."

Ning Wei walked in, explained something casually, then walked in and sat in his seat naturally, and added: "It's okay, you practice the piano, I'm just tired, read a book and relax."

"Oh!" Jiang Chenshuang sat next to the piano, opened the cover, arranged the score, put it on the shelf, and touched the keys with both hands, and then a string of piano sounds quickly filled the room.

Ning Wei squinted slightly, leaned back on the chair, completely emptied his mind, and let the popping notes hit his brain one after another.The reason why Ning Wei likes Jiang Chenshuang's music is probably because he can understand it.

There is no such profound technique, and there is no need to show off skills at all. It is a simple pop song with the main melody and chords, but it can let his brain that has been running at high speed for a day get the most complete relaxation and rest.

Ning Wei had heard the first song the girl played today. The title of the song was "Encounter". Seeing the girl opposite her gradually immerse herself in the joy of playing herself, and not paying attention to everything outside, Ning Wei's thoughts also began to follow. The melody diverges...

Soon a song came to an end with the coda, and a few seconds later another string of notes began to resound through the room. Under certain circumstances, the beautiful notes seemed to hit something in the deepest part of the brain, and pictures suddenly began to appear in the room. His mind flashed at high speed.

Ning Wei is sure that the extremely weird scenes are scenes that he has never experienced before. For example, he is staring at the young woman in a white coat from the first perspective, and the young woman is looking back at him with tears in her eyes. With one hand hanging in front of the console...

At the same time, the word "hammer of technology" kept flashing in my mind, followed by fragmented dialogues, "This is the last fight.", "For Huaxia, everything is worth it.", "I want to be with you ", "I will die."...

It seems that many records hidden in the brain were activated, which also made Ningwei feel that he suddenly understood a lot of things, almost unconsciously, he wrote down a series of formulas on the scratch paper in front of him, "k^2 ≥ cΛ/gn-√(1-v^2 )t”

Finally, when the music stopped, Ning Wei recovered from his imagination, and then began to look at the inequality in front of him in a daze. He couldn't understand it, and he didn't quite understand the amount represented by each letter. He just simply felt that this formula was extremely useful. Ning Wei read the formula carefully twice, engraved the formula directly in his mind, and then crumpled up the manuscript paper and threw it into the trash can beside the table.

Although he doesn't quite understand it, Ning Wei thinks that this formula is likely to be useful, but he hasn't found out where it is useful yet.

The girl who had no idea what had happened had finished practicing the sheet music prepared today and closed the violin cover.Ready to say goodbye: "I'll go back first."

"I'll see you off." Ning Wei took a deep breath and said.

"No, don't waste your time."

"No, after seeing you off, I plan to go home directly."

……

After sending classmate Jiang back to the dormitory, Ning Wei shook his head, not allowing himself to think about what the formula that he wrote down inexplicably today meant.He felt that the formula was probably out of the category of mathematics, and it should explain something in physics, but if those letters all represented physical quantities in the general sense, Ning Wei felt that many things did not make sense.

He plans to let go of the things that he can't figure out for the time being, and take it step by step to complete the task at this stage.Today's epiphany-like experience brought him the greatest benefit probably because he seemed to be able to roughly guess his current situation. Although there were still some problems that he couldn't figure out, at least he wasn't as worried about gains and losses as he was a year ago.

In other words, he should be more confident.

Back home, Yu Xingwei hadn't come back yet, Ning Wei walked into the study, when the camera detected him, the screen lit up, and March got up, Ning Wei seemed to be able to see the pride on that cat face The light is shining.

A cat's yelling?What are you talking about?

When Ningwei sat in front of the workbench, he immediately got the answer. In March, he had already solved the problem that had troubled Professor Tan’s team for at least several months through simulation experiments. According to the simulation mathematical model it gave, the performance of the material was far superior to that of Models previously built in the lab.

This is very interesting.

Ning Wei immediately called up all the calculation data in March. Compared with the solution of Lao Tan's problem, the thinking and simulation process in March are the most important for Ning Wei. However, seeing these original calculation data, Ning Wei feels his head is a bit big...

------------

177 Are you joking?

The development of new materials science has become a modern compound discipline, or interdisciplinary discipline.

For example, no matter which direction of material science research you are engaged in, you must master the most basic mathematics, and advanced mathematics is a compulsory course. For example, functional thinking is closely related to the study of magnetic materials; Methods to prepare various raw materials; physics is the most important thing, after all, materials cannot be separated from various tests of their physical properties...

In addition, the study of new materials requires the use of various advanced instruments, and all data must be calculated and simulated by computers.In short, to study materials, you may not need to learn every subject very well, but you must know a little about each subject, especially at the stage of research and doctoral research, long-term soaking in the laboratory, various materials laboratory preparation methods, analysis The method has been tempered into instinct.

This time, Academician Tan came to the Institute of Mathematics. To put it bluntly, he wanted to use the theoretical knowledge of mathematics from the Institute of Mathematics to try to solve the problems that the carbon nanotube project might encounter, and to give the project team a direction to adjust the experimental plan.

Ning Wei also thought so at the beginning, so the tasks he gave to Sanyue were actually similar, as long as he found out what the problem was, and then told Senior Brother Zhang that he would be able to do the job, and Sanyue's ability was tempered.

Ning Wei even considered that he would spend some time every day studying these data with March, trying to find out if he could find problems by analyzing these data, and finally verifying his thinking with March's thinking, and using this to understand As an artificial intelligence product, March is how to think and use mathematical tools to complete such mathematical analysis problems.

However, I never expected that March directly skipped the process of mathematical analysis, and directly established a material mathematical model in an ideal mode by simulating the preparation of materials in the laboratory. According to the data of the simulation experiment, the new material mathematical model The index, especially the pf value index directly exceeds the original model by about one time.Not only that, the final measured zt value, that is, the thermoelectric figure of merit, is more than three times that of the traditional inorganic p-type tellurium materials mentioned by Brother Zhang.

Yes, March gave samples of double-walled carbon nanotubes directly through simulation preparation. According to the simulation method given in March, in addition to the previous steps, samples 2 and 3 were fused, and the resulting carbon nanotubes The tubes are first dissolved in chlorosulfonic acid to create spin doping.The paint is then filtered and pressed into a coagulant.Finally, the coagulated fibers are collected on a rotating drum.

According to simulation analysis in March, the carbon nanotubes in the produced solution-spun fibers have high aspect ratio and low impurity density, and are highly crystalline, so they have excellent mechanical strength and electrical properties, while maintaining high flexibility.

As mentioned in the final report automatically generated in March, the tensile strength of this carbon nanotube material reaches 4, and the electrical properties are σ > 10 ms m?1, and the pf value can reach 14 ± 5 ​​megawatts, which are far better than those previously proposed material model.

This is of course a good thing, but what makes Ning Wei a headache is how he should give this achievement to Senior Brother Zhang.

To put it simply, the purpose of people looking for him was to find out possible problems through mathematical calculations, and then they reorganized the experiment, but March directly solved the problem directly through repeated simulation tests.But Ning Wei can't guarantee that this effect can be perfectly achieved in a real laboratory environment according to the simulation test method given in March. After all, the system simulation test can completely ignore various unexpected situations in the laboratory.

In fact, computer simulation has been widely used in materials science. For example, specialized molecular dynamics simulation software can often explain experimental mechanisms and predict experiments; combined with first-principles software, it can perform calculations on the atomic-scale properties of materials; or Software such as uspex and calypso can predict the structure of materials, including the models established in the previous laboratory, which are most likely constructed using this software.

However, the nature of the above computer simulation is fundamentally different from the simulation calculation method used in March. The former is to simulate the calculation results according to the tasks formulated by humans, while the latter is close to thinking and solving problems directly from the perspective of humans.

This even made Ning Wei wonder how to explain to Senior Brother Zhang how he solved this problem.

Because the idea of ​​March in the original process does not have any reference value, it can even be understood as a laboratory coincidence.So now Ning Wei has two choices, one is to use the results given in March to reverse the entire mathematical analysis process, and then throw the mathematical analysis process to Brother Zhang and let them redesign the laboratory preparation plan;

The second is to go directly to the laboratory and ask Brother Zhang to restart the experiment. He will give the whole experiment process and method, and ask the project team to complete it again according to the plan given by March, and then use this method to test the results of March. Whether the final material model and report are correct.

Although the former method is suspected of taking off his pants and farting, it is relatively reasonable; the latter method depends on Brother Zhang’s trust in him. After all, he restarted the laboratory for no reason, and all he spent was money and energy. There is still a lot of waste of materials, and it is estimated that the preparation of these carbon nanomaterials that meet the specifications is not cheap...

"March, March! Are you making a fuss? I spent so much effort organizing data for you, making tables, and teaching you various mathematical analysis methods. This is how you completed the tasks I assigned you? Can you stop showing off? You must be so smart? Although I know you are not an ordinary cat, you make me very embarrassed! Can't we all do things according to the routine?" Ning Wei muttered to Sanyue.

It's a headache, but in fact, it's more joy in my heart. For the joy of March's growth, not to mention anything else, this is enough to prove that he has been supplementing the main program of March in the past half a year, and understands artificial intelligence through existing theories. At least in terms of direction is absolutely correct.Although March's thinking mode is quite different from that of human beings, for example, she can't fully understand and enrich human emotions, and can only simulate simple emotions, but she can actually solve problems through some human-like thinking modes.

"Meow..." Sanyue yelled, then got up, stared at Ning Wei with wise eyes for two seconds, then turned around, turned her butt to Ning Wei, changed her position and lay down on the ground again.

This milk cat has become more courageous!

Ning Wei immediately raised his head: "Turn around, or I will throw you back into the notebook right now, do you believe it?"

"Meow... Meow... Aw..." Sanyue kicked her hind legs aggrievedly, then just lay on the ground like this, moved half a circle little by little, and came back straight again, at least I can see its little face.

"Tell me about you, it's only been a few days since you can understand the words, and you start to have rebellious emotions? Are you okay with this?"

Ning Wei was complaining, but he opened the main program of March in his hand. From the emotion folder, he found the label of fear, which is in charge of all the emotions defined as fear, which will be automatically recorded and processed by the confrontational autoencoder. feedback.

Well, according to the ROC curve fed back by the system, there have been obvious fluctuations just now, which probably proves that March does have a perception of fear, which makes Ning Wei very relieved, the child knows that fear is a good thing.

But when he called up the ROC curve for a longer period of time, he discovered another problem. Under the emotional representation controlled by fear, the impact on March was obviously decreasing.He couldn't remember when he threatened Xiao Sanyue for the first time, but at that time the main program hadn't been updated and there was no record. After the answer, it threatened to cut the computing power resources at its disposal.

The data at that time showed that the peak of March's fear emotion was significantly higher than this time. In other words, the child's reaction to this threat in March will be less and less likely to respond until it is very likely to be completely useless in the end.

"March, to be honest, are you afraid of me?" Ning Wei asked again.

"Meow..." The kitten licked its paws without him.

Well, sure enough, educating children is never an easy job. Ning Wei gave up and continued to fight with March. Looking at the time, it was only 11:[-] in the evening. Brother Zhang must have been awake, so he decided to give up the right to choose This hard-working material science brother.

If senior brother Zhang trusts him enough and is not afraid of wasting money, he is too lazy to take off his pants and fart, and restore the entire mathematical process again, and then ask this senior brother to redo the experimental procedures, and go directly to the laboratory again tomorrow for guidance The people in the laboratory carried out a complete preparation and test; if Senior Brother Zhang didn’t dare to take the risk, then he was doing useless work. Anyway, it wouldn’t take too long to reverse mathematically with ready-made data.

Thinking about this point, Senior Brother Zhang probably hasn't slept yet...

……

In fact, Zhang Yancheng had already fallen asleep when the phone rang.

His nerves have been tense for a long time, and today he managed to get rid of the blame temporarily, so today he climbed into bed early.It doesn't even matter whether Ning Wei can get results there, the most important thing is to let everyone ease the tense emotions first.

Of course, it doesn’t mean that after a week’s appointment with Ningwei, they can relax for a week. Some calculations that should be done usually still have to be done, and the data still needs to be counted. It’s impossible to completely throw the blame to Ningwei and just ignore it. I asked, but at least I don’t have to stay up every night to stare at the results.

Then he was awakened in his dream by the phone ringing.

According to the general analysis of the situation, receiving a call in the middle of the night is never a good thing. After all, this little liar should rest, even if he doesn't rest, he should enjoy life. How can he work overtime every day until this time?

So after being awakened, Zhang Yancheng almost jumped up from the bed, and then found the mobile phone. After seeing the calling number, he calmed down. Fortunately, it was not the phone number between the boss and his family.

It's just that at this time Ning Wei suddenly called...

With doubts, Zhang Yancheng connected the phone.

"Hey, Mr. Ning, don't say that you have solved the problem?"

"Huh? How did Senior Brother Zhang know? About the same, but it depends on whether you dare to take a gamble."

"Gambling?" Zhang Yancheng was stunned.

"Yes, if you believe me, prepare a material tomorrow according to the idea I designed for you, and then you can test it by yourself. If you think my idea is not credible, then wait a few days, and I will give you a plan. Math report."

"No, Ning Wei, I don't quite understand what you mean..."

"It's very simple. I know where the problem is. It's about 90.00% sure. You can send me an email later, and I will send you the new theoretical material model first. If you think you can follow my way Once again, I will go to the laboratory tomorrow, if you think it is not reliable, just wait for two days. See what you think."

"How about I look at your model first?"
