Chapter 713 The target is the sea of stars! (Part 1)
"...."
I don’t know if it’s Chen Ning Yang’s illusion.
He always felt that after not seeing Lu Guangda for more than ten years, his old friend had changed a lot:
In his impression, Lu Guangda was an extremely shy boy, the kind who would be shy even if a girl looked at him twice. He was a good boy in the eyes of many people.
When Yang Zhenning was a child, Yang Zhenning encouraged Lu Guangda and him to go to Tsinghua University to secretly cut the sunflowers at the neighbor's professor's house. Lu Guangda hesitated for a long time and did not dare to use the scissors.
Now they meet again after 11 years. They have already started a family and have their own pursuits and beliefs.
At the age of forty, Yang Zhenning will naturally not think that Lu Guangda is still the silly and shy boy.
but......
It's one thing to stop being silly and sweet, but it's another thing to like to talk dirty.
Nowadays, Lu Guangda has not only become a bit darker, but his words have also become more and more riddle-like. He is always talking about donkeys and donkeys. Those who don't know better think that the donkey is the protagonist.
However, although Lu Guangda did not explain clearly, Yang Zhenning's IQ naturally understood what he meant at this time:
The "other donkey" Lu Guangda was talking about was probably a domestic scholar with profound knowledge in theoretical physics.
If nothing unexpected happens.
Most of this person has made outstanding contributions in the meta-hadron model, but due to some reasons cannot make his name public.
only.....
Who could this person be?
The top theoretical physics scholars in the country are none other than Zhao Zhongyao, Wang Ganchang, and several others. Basically, they were all well-known or well-known before returning to China.
Now that their names have appeared on the front page of the journal, they obviously have nothing to do with the donkey.
But if it were someone else...
It’s not that Chen Ning Yang is belittling the motherland, but objectively speaking, there is indeed no possibility of cultivating top theoretical physicists in China today.
Of course.
If Yang Zhenning could know about the achievements in the future, he would probably change his views.
Think of this.
Yang Zhenning couldn't help but feel a little curious, so he quickly nodded and said to Lu Guangda:
"No problem, Guangda. Should we set off to meet that comrade, or should we contact him remotely?"
Lu Guangda pondered for a moment and explained:
"Zhen Ning, we are old acquaintances, so I will just say some things directly - if you want to meet now, it will probably be a bit difficult."
"After all, that comrade's current situation is quite special. It may take some time for you, Zhenning, to meet him."
"So let's do this. I'm going to contact Lao Wang, who is in charge of this matter, and see if I can give you two an opportunity to communicate on the phone."
Yang Zhenning nodded with understanding:
"OK."
Although Yang Zhenning had a tacit understanding from the beginning of the meeting and did not ask Lu Guangda about his current work content, he already had some answers to this question in his mind:
Lu Guangda could only be researching the atomic bomb.
After all, it has been mentioned countless times before.
The fact that the Rabbits are engaged in nuclear engineering is not something... or it cannot be concealed. The search for uranium mines was even a national-level action.
Therefore, the so-called confidentiality goals of nuclear weapons research and development are mainly the research and development progress of the project and the location of the specific factory.
So if nothing unexpected happens.
That Comrade Donkey should also be a member of the atomic bomb project. Now that Yang Zhenning and the others have just returned to China, it is obviously impossible to meet him offline.
Various subsequent political reviews are inevitable steps, and to put it more seriously... among the more than 100 people who returned home this time, there may not be any enemy agents who returned home with missions.
After all, Yang Zhenning doesn’t know all of these people. Some of them are even meeting for the first time, and they don’t even know the other person’s true abilities.
The only thing Yang Zhenning can guarantee is that Li Zhengdao, Chen Shengshen and other top bosses he is familiar with will never do anything to betray the country and seek glory, and that's it.
Therefore, relevant review is a necessary step, which Yang Zhenning can completely understand and accept - the Qian Fifth Division received much stricter review across the sea back then, and at least they could move relatively freely.
Seeing that Yang Zhenning accepted the remote communication plan, Lu Guangda poured him a glass of water, turned around and left the reception room to contact the capital.
Two hours later.
When the time came to ten o'clock in the evening, Lu Guangda opened the door again and walked in with a relaxed expression:
"Zhen Ning, all parties have been contacted. The other party is now online. You can come over and talk on the phone."
After hearing this, Yang Zhenning carefully put away the "Quotations" he was reading, stood up from his seat and straightened his clothes:
"Okay, Guangda, please show me the way."
Lu Guangda said politely, walked to Yang Zhenning and put away the journals and calculation papers he had brought:
"Come with me."
Then under the leadership of Lu Guangda.
The two soon came to a room located at the innermost part of the guest house. Lu Guangda pointed inside:
"Zhen Ning, this thing on the phone can only be used for one-on-one conversations, so I won't go in and join in the fun."
"Today I will act as a guard for you, the 'returnee', and I will be on duty outside!"
Yang Zhenning smiled and punched Lu Guangda on the shoulder. Without saying anything, he opened the door and walked in.
Lu Guangda pulled the cord of the electric light at the entrance, and after the light came on, he gently closed the door.
This is a windowless room with an area of about ten square meters. As soon as you enter the room, you can see a wooden desk and a phone on the desk.
Judging from the decoration style, this should be a place like the reception liaison office, but some other documents have been temporarily transferred.
At this time, the phone's microphone had left the body and was placed sideways on the table. There was also a stack of blank arithmetic paper and two pens neatly placed on the table.
Yang Zhenning nodded upon seeing this, put his briefcase aside, walked quickly to the desk and picked up the phone.
But when the microphone was put to his mouth, Yang Zhenning remembered something:
Lu Guangda seems to have not told him the specific name of this comrade...
However, at this time, the noise in the room had already reached the other end of the phone, and the door was closed by Lu Guangda. Naturally, Yang Zhenning could not put down the phone and ask Lu Guangda what the other party's name was.
So he hesitated for a moment and said:
"Hello, I am Yang Zhenning. Are you... Comrade Donkey?"
at the same time.
Base 221 thousands of kilometers away.
Xu Yun, who was originally holding the microphone with both hands and his expression was tense and excited, heard the words, and the expression on his face suddenly turned into confusion:
"OvO?"
After three or four seconds, Xu Yun finally came back to his senses.
He took a deep breath, forced himself to calm down, and said:
"Mr. Yang... ahem, Mr. Yang, hello, my name is Xu Yun - if the Comrade Donkey you are talking about comes from Director Lu Guangda, then he should be referring to me."
Say it.
Xu Yun also had a trace of emotion on his face.
He never expected that he would actually meet Mr. Yang in the dungeon.
After all, it follows the historical trajectory.
Mr. Yang will return to the mainland for the first time in ten years. By then, he will have left this era for a long, long time...
With the help of the yuan-hadron model, Mr. Yang unexpectedly returned to China early together with Chen Shengshen, Li Jingjun, Li Zhengdao and other big guys - and it was a settled return.
At this time, Mr. Yang was only in his early 40s. He was still in the prime of life and was completely different from the frail old man in later generations. This was evident from his energetic voice.
so good.......
And the other side.
Xu Yun's answer was not very humorous, but it was still quite individual in this relatively staid era. Even Yang Zhenning couldn't help but be stunned.
But soon he held onto the microphone, with a hint of apology on his face:
"Comrade Xu Yun, hello, hello. I'm really sorry. Guangda didn't tell me your name before, so..."
"Hey, it's nothing."
Although the other party could not see his expression through the phone, Xu Yun still waved his hand:
"It's okay to be a donkey. Anyway, I've gotten used to it during this period of time. I'm still a little uncomfortable not hearing the word donkey for a long time."
"By the way, I'll give you a vaccination. If you hear someone say something like tweet, tweet, tweet, 30,000 tentacle monsters updated every day, roast chicken, medium rare, etc., most of them are referring to me."
Yang Zhenning:
"?????"
Then Xu Yun coughed lightly and continued:
"Okay, Mr. Yang, our time is limited, so let's talk about business."
Only then did Yang Zhenning realize that he was not across the sea, and a phone call consumed a lot of resources, so he quickly secretly muttered:
"No problem, Comrade Xu... Comrade Xu, right? I wonder if Guangda has relayed the situation to you in detail?"
Xu Yun nodded. With Lu Guangda's character, he had naturally handed over this matter long ago::
"Well, Director Lu has already introduced you."
Yang Zhenning asked:
"In that case, Comrade Xu, do you have any opinions?"
"Just call me Xiao Xu."
Xu Yun corrected Yang Zhenning's title smoothly, and then said:
"As for ideas... To be honest, I have some."
Yang Zhenning suddenly raised his eyebrows:
"Oh? I'd like to hear the details."
He had never had any interaction with Xu Yun before. At the same time, the honor of the Nobel Prize and his own personality made Yang Zhenning very confident in academic aspects - to put it bluntly, he didn't trust people very much.
But on the other hand.
The facts of the meta-hadron model are also before us. If Xu Yun really played an important role in the derivation of the meta-hadron model, then his ability must not be underestimated.
The intersection of two completely different mentalities caused Yang Zhenning to fall into a state of 'duality of belief and doubt' - sometimes believing, sometimes doubting.
However, Xu Yun didn't know Yang Zhenning's inner thoughts. He quickly pulled out the mind map he had just taken the time to write down and said:
"Mr. Yang, let's talk about the issue of dark matter first - I don't have much opinion on this aspect. I mainly want to synchronize information with you."
"Not long ago, Comrade Wang Ganchang discovered a case with a binding energy of 1.26812 MeV, which was a hyperon numbered 4685."
"Based on the joint derivation just completed by comrades in the theory team, we believe that dark matter should have some relationship with this 4685 hyperon."
"Either the dark matter can be maintained independently in the binding energy range, or it has a certain companion property with the 4685 hyperon."
"What did you say?!"
After hearing this, Yang Zhenning's eyes suddenly widened:
"Comrade Xu, are you telling the truth?"
Xu Yun nodded heavily:
"Of course it's true, Mr. Yang, you are currently qualified to access the relevant data. Just now...well, we have already sent the parameters."
"The file recording the parameters should be near the phone. You should be able to figure it out once you find it."
Swish——
Xu Yun just finished speaking.
Yang Zhenning put down the phone and quickly searched for it on the table.
as expected.
A few seconds later.
He found a light yellow sticky note on the other side of the phone that was smaller than calculation paper and recorded some parameters.
So Yang Zhenning couldn't wait to hold it in front of him and looked at it carefully.
In the past two months, Yang Zhenning has repeatedly deduced the mathematical properties of dark matter in the standard framework. At this time, faced with this data, he quickly entered the derivation state.
"The transition state function refers to the transition of the beryllium-8 atomic nucleus from a high energy state to a low energy state, so the recombination energy should be 426.984..."
"The canonical momentum corresponding to qi is pi=?L?q˙i...So the canonical momentum density can be defined as π(r,t)=?L?(?tΨ)..."
"So the Hamiltonian of the system is H=∫(π(r,t)?tΨ?L)d3x...."
This chapter is not over, please click on the next page to continue reading! "...The operators have the following basic commutation relations, [π^(r,t),φ^(r′,t)]=
"Therefore, the Laplace density function of its free real scalar field φ is L=?12ημν?μφ?νφ?12m2c2?2φ2=12c2?tφ2?12(?φ)2?12m2c2?2φ2...."
at the same time.
Hearing the swishing sound of writing on the other side, Xu Yun at Base 221 couldn't help but shake his head.
Everything in the world is so magical sometimes, and the existence of some coincidences can really make you feel inexplicably curious and aware of the word fate.
On the first day when the tandem accelerator was powered on, Wang Ganchang discovered signs of the existence of 4685 hyperons. (See Chapter 629)
Xu Yun is very familiar with this particle. It is the key directly connected to the isolated point particle.
However, due to timing issues at that time, Xu Yun was not very good at throwing out the existence of lone point particles.
Unexpectedly, Yang Zhenning actually deduced the possibility of the existence of dark matter through the standard model.
This way.
While Lu Guangda was relaying the news, Xu Yun smoothly informed everyone of the existence of 4685 hyperons and solitary point particles.
The whole process was so smooth that even the experts in the base who didn't know Xu Yun's origins didn't feel the slightest abnormality.
What made Xu Yun feel even more subtle was...
The people who played a key role in the verification of solitary point particles in later generations...
It’s Mr. Yang!
Unexpectedly, in another time and space, Yang Zhenning would actually form a bond with the solitary point particle again...
Mr. Yuan and Huahua, Yang Zhenning and Lone Point Particles, Xu Yun and Donkey... In different time and space, some things still echo each other, which is really amazing.
Xu Yun then quietly waited for the result by the phone. Since the parameters provided by the base were sufficient, it only took Yang Zhenning more than ten minutes to send the reply again:
"Xiao Xu, you are right, the data of this particle is abnormal!"
"It shows non-spontaneous coupling in many parameters, and this meson doesn't seem to be quite right..."
"Of course, these are just mathematical derivation. As for whether it is really related to dark matter, we have to wait for application verification."
"But no matter what, you have brought great help to our work, Xiao Xu, thank you for your hard work!"
Xu Yun corrected the title problem shortly after the call was connected, but before Yang Zhenning calculated the data, he still called Xu Yun "Comrade Xu" - there is nothing wrong with this title, but it is a bit polite and unfamiliar.
It has a bit of a business-like feel.
But now he has changed his name to Xiao Xu, and his tone is obviously much closer. This shows that he has initially recognized Xu Yun's ability.
This is a good thing.
Then Yang Zhenning paused, thought for a moment, and then said to Xu Yun:
"Xiao Xu, I have a personal request... It is the parameters of this 4685 superon. Can it be shown to others simultaneously?"
"other people?"
Xu Yun subconsciously wanted to reply that this would definitely not work, but when he was about to say the words, he suddenly thought of something in his heart:
"Mr. Yang, the other person you mentioned...could it be Mr. Li Zhengdao?"
Yang Zhenning nodded:
"That's right."
"Is it because of your bet?"
"Well, it would be so unfair to him if this parameter was not synchronized to him."
Xu Yun then touched his chin with understanding.
Sure enough, it was Li Zhengdao...
Lu Guangda had mentioned the news about Yang and Li's new appointment in the previous phone call - after all, the purpose of coming to Xu Yun was to give him advice, so this matter must not be hidden from Xu Yun.
So Xu Yun already knew about the existence of this bet before he answered the phone.
Objectively speaking.
Xu Yun agreed with this bet.
After all, if the original historical development were to follow, the contradiction between Yang and Li was destined to be impossible to reconcile, even if they returned to China early now, it would still be impossible.
To know.
The previous president of the Chinese Academy of Sciences, the top leader of the Ministry of Science and Technology, and other big figures in later generations all tried to mediate the conflict, but they were sternly rejected by Yang and Li.
Even a certain big shot who had stepped into the power center of China and whose job title was a forbidden word also proposed the idea of being a middleman, but in the end he still failed.
During the period when Xu Yun traveled through.
Yang Zhenning is over 100 years old and has lived in his home at Shuimu University all year round and is in a state of recuperation.
Lee Tsung-dao is about to turn 97. He suffered a serious waist injury in his early years and is now unable to fly.
In 18 years, Li Zhengdao's condition worsened across the sea. It was his son who drove across the sea in a car and spent nine days taking him to his home in San Francisco to recuperate.
Therefore, later generations of Yang and Li have basically lost the possibility of meeting offline. Even if they really want to chat, it can only be done by phone or video at most.
Therefore, if the two of them can make a 'right or wrong' decision through this so-called new bet, Xu Yun doesn't feel it is so cruel.
Now that Yang Zhenning wants to synchronize this parameter to Li Zhengdao, he is naturally worried that his opponent will be pulled back because he does not master the parameters.
After all, these parameters were not created by Chen Ning Yang or Chen Ning Yang’s team. It would be unreasonable for him to hide his secrets.
Yang Chenning and Li Zhengdao are both stubborn, but stubbornness does not mean they are villains. They still have some bottom lines.
So Xu Yun thought for a while and said to Yang Zhenning:
"Mr. Yang, I have received your request. I will forward it to the organization later for the leaders to make a decision."
"Of course, this is just an official statement. With Mr. Li Zhengdao's status and achievements, the possibility of this appeal being passed is almost 100%."
This chapter is not over yet, please click on the next page to continue reading! Yang Zhenning nodded slightly, his expression holding the microphone did not change much:
"I understand, okay Xiao Xu, let's stop here first about that person."
"We have now finished discussing dark matter, is it time to discuss the next topic?"
Upon hearing this, Xu Yun immediately sat upright for a few minutes, and at the same time turned the mind map to the next page:
"No problem, Professor Yang, let's talk about gravitational waves next."
"Director Lu has already reiterated your ideas to me. I personally have no objections to the derivation process of gravitational waves."
"At the same time, I also quite agree with the conventional gravitational wave measurement plan. The interferometer is the optimal solution in this field."
"Of course, I would like to make a personal suggestion in this regard. You can contact more comrades from the Computer Institute in the future."
"Computer lab?"
Yang Zhenning blinked. At this time, his opinion of Xu Yun was no longer as hesitant as before:
"Xiao Xu, are there any new results over there?"
Xu Yun hummed, but didn't explain much.
Chen Ning Yang’s design plan for conventional gravitational waves is basically the same as that of later LIGO. However, due to the limitations of the times, Yang Chen Ning’s plan is somewhat more conservative than LIGO.
For example, in Xu Yun's view.
The optical path refraction designed by Yang Zhenning can increase the number of refractions by about 50%, and the vacuum rate can be relatively reduced.
However, these are all minor details in the project implementation. It has no practical significance to bring them up at this time. On the contrary, they may make Yang Zhenning a little unhappy.
So Xu Yun changed the topic and drew Yang Zhenning's attention to the Computer Institute.
because......
In addition to the 'accuracy' of gravitational wave detection equipment, there is another very critical thing - analysis software.
And what a coincidence.
When Xu Yun was chatting with Ye Duzheng, he had a detailed discussion with Qian Bingqiong about domestic industrial software.
Now the rabbits have put the research and development of industrial software on the schedule. Although this thing cannot produce results in one or two years, the gravitational wave detector will not be put into use so soon.
If everything is normal.
The first-generation version of the gravitational wave detector should be initially completed in eight years, then undergo maintenance and acceptance for about two years, and finally be officially put into operation ten years later.
At that time, the first generation of industrial software should have almost come out. If Yang Zhenning can maintain close enough contact with the computer institute, then it is entirely possible to customize the software...that is, use the gravitational wave detector as a
Possibility of industrial software pilot.
At the same time, the data that needs to be analyzed for gravitational wave detection is extremely large, enough for computers to iterate software versions for a long time.
So in Xu Yun's opinion.
Gravitational wave detectors and industrial software are inherently good partners, and they can complement each other stably in the long term.
Then Xu Yun briefly introduced the matter of industrial software to Yang Zhenning. With Yang Zhenning's vision, he quickly understood the importance of industrial software.
A few minutes later.
After listening to Xu Yun's introduction, Yang Zhenning was silent for a while and suddenly asked:
"Xiao Xu, is this your personal idea, or was it entrusted by the organization to relay it to me?"
Xu Yun on the other end of the phone smiled:
"It's just my personal idea. I haven't reported it to the organization yet - after all, there was too little time left for us to prepare."
Yang Zhenning nodded slightly, and his view of Xu Yun changed slightly.
The analysis module of the gravitational wave detector is indeed a link that has been somewhat ignored by him.
Previously, he and Lu Guangda focused on relatively "hard" equipment parameters such as equipment accuracy and core material splicing, but they somewhat ignored the "soft" module of analysis software.
Of course.
This also has something to do with today's technological level.
These days, integrated circuits have just come out less than two years ago. The concept is very popular but no real chip has yet been released, so a lot of data analysis is stuck at the level of 10,000 to 30,000 times per second.
Sometimes conditions are limited, and even scholars across the sea will choose to use equipment such as slide rules to perform calculations by hand.
In addition, Yang Zhenning and Lu Guangda were focused on the ultimate goal of quantized gravity, so they subconsciously did not take into account the analysis of data during the discussion.
True.
If the rabbits really want to implement this project, they will definitely find this overlooked link during verification.
But in this way, Yang Zhenning will be a little embarrassed when the time comes - again, there are many people burning themselves for the motherland these days, but there are also some self-interested and jealous people. Not everyone is interested in Yang Zhenning and Li Zhenning.
Masadao returned to his country with good intentions.
If Yang Zhenning is caught off guard, there will be some shady rumors about him.
Therefore, Xu Yun's approach actually helped Yang Zhenning resolve some troubles.
Think of this.
Yang Zhenning is even more curious about Xu Yun:
"Xiao Xu, may I ask how old you are this year?"
"Seventeen years and more than ninety months old."
"Who did you learn from? Where is your hometown? You're not still single, are you?"
Seeing that Yang Zhenning was about to turn into a marriage-rushing party, a black line suddenly appeared on Xu Yun's forehead:
"Um...Mr. Yang, I believe you will know this information in a while. Let's continue the previous topic now."
Then he didn't wait for Yang Zhenning to answer.
Xu Yun took the first step and said quickly:
"Now we have one remaining problem, which is the situation that you and Director Lu discussed about the space exploration equipment arm being not long enough."
"To be honest, the robotic arm is definitely not capable of crossing the length of the Kuiper Belt, but..."
"Have you ever thought about changing your thinking and using other things to measure those lower-frequency gravitational waves?"
"something else?"
Yang Zhenning, who had just been brought back to reality by Xu Yun, was suddenly startled:
"Is there anything that can do this?"
Thousands of kilometers away.
Hearing Yang Zhenning's question, Xu Yun couldn't help but look up at the stars outside the window:
