Volume 1: Student Life Chapter 460: The Person Who Brings Inspiration
After Coyle and Matheson came to see Chen Zhou, no one came to disturb Chen Zhou anymore.
The only thing that might have surprised Chen Zhou was that Professor Friedman came after Coyle and the other man.
Still haven't found him.
This was completely unexpected for Chen Zhou.
In Chen Zhou's guess, the purpose of these two people coming here was very clear.
After leaving, they would more or less mention to Professor Friedman that they had come to see them.
Then considering Professor Cross's complaints in the middle, it is a bit puzzling why Professor Friedman did not look for me.
However, if I can't figure it out, I won't think about it anymore.
Chen Zhou, who devoted himself to mathematics and physics, increased his pace again.
December 25th.
Christmas for the American people.
LIGO has also started its holiday mode.
Yang Yiyi returned to MIT on her own.
In fact, LIGO started its holiday three days ago.
However, because of the unprocessed research materials at hand, Yang Yiyi stayed until the last day.
At this time, MIT was already immersed in the joy of the New Year.
This joy is in the atmosphere, not in the number of people.
Because there are not many teachers and students staying at MIT.
Most of them are Chinese students.
But Christmas actually has no meaning at all for Chinese people.
In the dormitory, Chen Zhou put down his pen after finishing the last line of math formula.
I looked at the time and it was already time for dinner.
He tilted his head slightly and looked at Yang Yiyi who was sitting at another desk.
At this time, Yang Yiyi was still immersed in her own research world.
From following Professor Weiss to going to LIGO, there has been a certain deviation in the physics research directions of Chen Zhou and Yang Yiyi.
The two people were also moving forward on their own paths.
Chen Zhou slowly stood up, walked behind Yang Yiyi, and leaned over to take a look.
After seeing the contents of Yang Yiyi's notebook, Chen Zhou couldn't help but smile.
No matter what other people's research methods are, at least Yang Yiyi was deeply influenced by Chen Zhou.
Both of them used a method of using a large amount of literature to sort out the research context of the topic and then find the directional method.
However, compared to Chen Zhou, he has an excellent mathematical foundation and the magical tool of wrong question collection.
Yang Yiyi will need to spend much more time and energy on this.
But compared to ordinary people, Yang Yiyi, who was deeply influenced by Chen Zhou, was much stronger.
Although that directional judgment largely comes from Yang Yiyi's own accumulated experience.
But it also reflects Yang Yiyi's nature as a top student.
She seemed to have the keen intuition of a natural physicist.
This was also praised by Professor Weiss, a potential Nobel Prize candidate.
So, when I saw that Yang Yiyi was also using this method and had gradually found her own way.
Chen Zhou was still a little excited in his heart.
As if she sensed the presence of the boy behind her, Yang Yiyi looked back in confusion.
When he turned around, his eyes met Chen Zhou's.
Smiling at Chen Zhou , Yang Yiyi asked softly, "What's wrong?"
"Nothing..." Chen Zhou said, and put his arms around Yang Yiyi, resting his head on hers, and said softly, "I just miss the days when you were by my side. Now that I'm alone every day, I miss you so much..."
Yang Yiyi put down the pen in her hand and said gently: "When you are not around, I miss you too..."
Yang Yiyi immediately smiled mischievously: "But when I'm busy in the laboratory, I can only take time to think about you."
Hearing this, Chen Zhou deliberately curled his lips and said, "Then I can only be ranked second? Your physics is the first?"
Yang Yiyi tilted her head, thought for a moment and said, "That's not the case. You two are... tied for first place..."
Chen Zhou chuckled softly and slowly loosened his arms.
Yang Yiyi immediately stood up, looked at Chen Zhou and asked, "When I was away, were you well behaved? Did that senior sister Nott do anything to you?"
Chen Zhou quickly shook his head: "What can she do? I am almost in seclusion every day, it would be hard for her to find me."
Yang Yiyi: “Really?”
Chen Zhou: “Of course it’s true!”
Yang Yiyi deliberately showed an expression of disbelief: "Huh?"
Chen Zhou looked at the girl in front of him, without further explanation, he kissed her directly.
Chen Zhou was deeply in love with this kiss.
This kiss expresses all my longings.
After a long time, they parted lips and teeth.
Yang Yiyi, who finally took a breath, heard Chen Zhou's vicious voice: "Do you believe it now?"
"Hmph!" Yang Yiyi snorted.
Since it is Christmas, Chen Zhou and Yang Yiyi decided to give themselves a short night off.
It wasn’t for the events held in the apartment building, but just for the warmth after a long absence.
After being at MIT for so long, the two have a pretty good understanding of the school.
But the world outside the school is not so familiar to the two.
Boston, a shopping paradise, is naturally also a paradise for couples to date.
Of course, when dating Yang Yiyi, delicious food is indispensable.
Second, anything else fun.
After a crazy night, the two of them enjoyed the joy of being together.
Other familiar friends were also tactful and did not disturb the two.
The next morning, the two got up early as usual for a morning run.
Because of the holiday, the senior sister Nott that Yang Yiyi was talking about and thinking about in her heart did not show up.
Chen Zhou naturally noticed this and just chuckled and shook his head.
Sure enough, girls are all jealous.
Regardless of whether that person is a threat or not.
After finishing their morning run, the two of them quickly had their breakfast in the cafeteria.
Although most students have started their vacation life, the school still has two cafeteria windows open.
On the way back to the dormitory from the cafeteria, Chen Zhou said softly: "In about half a month, we will return to China."
Yang Yiyi nodded gently: "Well, we will go back when you finish the work in your hands."
"Yeah." Chen Zhou responded and said nothing more.
Yang Yiyi's work cannot be solved in a short time, and there is no rush to get results.
So, she was waiting for Chen Zhou's time.
And Chen Zhou finally entered the final battle.
This battle involves two points.
One is the linear representation of Artin's L function of the Galois group, which is just a little short of the key inspiration.
If this inspiration comes, Chen Zhou will solve this problem quickly.
And represents his voice in the field of algebraic geometry.
But if this inspiration had not appeared, Chen Zhou would have been stuck forever.
As for the subject of Goldbach's conjecture applied for in the national "Thousand Talents Plan", there has been little progress.
Chen Zhou's idea of using algebraic geometry to perfect the distribution deconstruction method and ultimately apply it to the Goldbach conjecture also came to a standstill.
The hope for a possible breakthrough also lies in the only inspiration needed for the topic of linear representation of Artin's L function of the Galois group.
As for whether this point will eventually lead to a breakthrough from point to line and then to surface.
Chen Zhou wasn't quite sure either.
After all, solving the Goldbach conjecture requires innovative mathematical tools and mathematical thinking.
Without a final result, any innovation is just innovation.
Even with guidance from a collection of wrong questions.
Because a collection of wrong questions won't give you the creativity you need.
Another key point in the battle is the detection method of the jelly ball experiment.
Chen Zhou can correct the modification of specific experimental parameters and the derivation of experimental data by relying on data processing, analysis of experimental literature, and guidance from wrong question collections.
However, in terms of detection methods, directionality alone is not enough.
Just like the innovation required by the Goldbach conjecture.
Therefore, even if the completed research results are excellent papers that can be published in "Nature" or "Science".
For Chen Zhou, the practical significance is still not great enough.
He wanted to find the jellyball that existed only in theory.
Looking at Chen Zhou who was lost in thought, Yang Yiyi asked, "Are you thinking about the topic?"
Chen Zhou nodded: "Well, there are difficulties that cannot be overcome."
Yang Yiyi thought for a moment and said, "Tell me about it?"
"One is a difficult mathematical problem in the field of algebraic geometry, which requires solving the linear representation problem of Artin's L function of the Galois group."
"I have now completed the connection between the Galois group and Artin's L-function, but when it comes to proving the final result, there is always something missing..."
While Chen Zhou and the other man were talking, they had already returned to the dormitory.
When he came to the desk, Chen Zhou picked up the draft paper covered with mathematical symbols and formulas, pointed to the content on it, and told Yang Yiyi about his research without reservation.
Yang Yiyi actually cannot give any substantive suggestions on difficult problems in the field of algebraic geometry.
Although a good physicist must be an excellent mathematician.
But Yang Yiyi currently cannot reach that level yet.
But after listening to Chen Zhou's words, Yang Yiyi still said: "Although I don't know how to solve this problem, but if it were me..."
Yang Yiyi hesitated for a moment before continuing, "I should start with the linear representation of Artin's L function, and then look for the connection with the Galois group, which can be regarded as a result of the relationship..."
What Yang Yiyi said were just her thoughts, although she also knew that she couldn't give Chen Zhou any more constructive advice.
But saying it or not saying it is different.
But after hearing what Yang Yiyi said, Chen Zhou was stunned for a moment.
Chen Zhou, who had long been accustomed to seeking results from causes, had never really tried the method of seeking causes from results as Yang Yiyi mentioned.
Moreover, Yang Yiyi's words also provided Chen Zhou with more associations.
Since the linear representation is the result, we can not only verify the linear representation of Artin's L function first.
There is also the relationship between the Galois group and linear representation, or the derivation principle...
Looking at Chen Zhou who fell into thought again, Yang Yiyi did not interrupt him this time.
However, she felt a little strange. Could it be that such a simple idea of hers could bring inspiration to Chen Zhou?
Chen Zhou didn't know whether he had such a thing as inspiration.
But often a word from an outsider can bring unexpected results to those involved.
Chen Zhou now feels that this is how he is.
Yang Yiyi's unintentional words might bring him different results.
After a long time, when Yang Yiyi was already sitting at the desk, Chen Zhou moved slowly.
He was not in a hurry to write extensively on the draft paper.
Instead, he glanced at the draft papers in his hands and slowly put them back on the desk.
Then, he picked up the draft paper about the rubber ball experiment class.
Walking to Yang Yiyi's desk, Chen Zhou handed her the draft paper and said softly, "Yiyi, take a look first. Do you have any suggestions?"
Yang Yiyi reached out to take the draft paper and looked at it carefully.
Although she didn't know what Chen Zhou was thinking just now, she would definitely not refuse what Chen Zhou said.
Chen Zhou’s idea is actually very simple.
The difficult problem in the field of algebraic geometry is not too difficult to verify.
Even though he had far more ideas than Yang Yiyi's suggestions.
That was only a matter of two or three days.
Compared with this difficult problem in the field of algebraic geometry, Chen Zhou feels that the difficulties in the glue ball experiment and the suggestions that Yang Yiyi may put forward are truly more constructive.
After all, how did LIGO detect gravitational waves?
What is Professor Weiss’ greatest contribution?
This is the method for detecting gravitational waves!
A stone from another mountain can be used to polish a jade.
In a sense, there are great connections between various disciplines in physics.
Chen Zhou wanted to find a suitable way to detect the rubber ball from the disciples of the "Detection Master".
After Yang Yiyi finished reading it, she also understood Chen Zhou's intention.
He turned to Chen Zhou and said with a smile: "LIGO is the Laser Interferometer Gravitational Wave Observatory. It is completely different from the way you observe glue balls at SLAC."
Chen Zhou didn't mind and said, "That's okay, I just want to know what you think."
"Well... okay then..." Yang Yiyi said, and took another look at the contents on the draft paper in her hand.
To be honest, she has always been amazed at Chen Zhou's research methods.
The contents she now holds in her hands also make her sigh with admiration.
Although she learned the same method from Chen Zhou, she felt like a child in comparison.
And Chen Zhou is a giant.
After a while, Yang Yiyi said, "I won't talk about the principle or anything like that. Let me tell you about some of the characteristics of the LIGO detector."
"Okay." Chen Zhou nodded.
There is really no need for Yang Yiyi to explain the principles in detail.
Chen Zhou had learned about it himself before.
After all, I still need to pay some attention to my girlfriend's research content.
"LIGO has three detectors at two sites. Two detectors with arms of 4 km and 2 km are built in Hanford, Washington, and one detector with arms of 4 km is built in Livingston, Louisiana..."
"LIGO's anti-vibration system can suppress all kinds of vibration noise, the vacuum system is one of the largest and purest systems in the world, and the optical device has unprecedented precision and can measure displacements a thousand times smaller than the size of a proton!"
"The computer facilities are powerful enough to process huge amounts of experimental data, and the best sensitivity has reached the order of 10. During the S6 scientific detection, its laser power was increased from 10 watts to more than 30 watts, and the detection range was expanded by 8 times!"
"After that, the 'Advanced LIGO' upgrade plan was carried out. The laser power was increased from 10 watts in the initial version of LIGO to about 200 watts, and the lower limit of the detection band was extended from 40 Hz to 10 Hz. The sensitivity is 10 times higher than that of the initial version of LIGO!"
"This means that LIGO can detect gravitational waves 10 times farther than before, and its detection range has been expanded by more than 1,000 times, and the number of possible gravitational wave sources that can be detected is 1,000 times more than before!"
"As for specific detection, the detection band selected by LIGO is often in..."
Although Yang Yiyi's voice was flat, as she spoke, Chen Zhou began to calculate the specific meaning of these data in his mind.
The so-called reference value also lies in these specific meanings.
In fact, the most direct manifestation of the detection method often depends on the sensitivity of the detection instrument.
The detector that can meet the instrument sensitivity requirements is the most suitable detector.
"In addition, the Virgo Interferometer, or VIRGO, near Pisa, Italy, is a ground-based laser interferometer with two arms 3 kilometers long that participated in the final part of the S5 detection. VIRGO also has a sensitivity comparable to that of LIGO."
"This interferometer is currently undergoing an upgrade to 'Advanced VIRGO'. According to Professor Weiss, after the upgrade is completed, it will officially join LIGO and operate together with the current two detectors."
"By then, the three detectors should be able to give a more accurate picture of the location of the gravitational wave source..."
Although Yang Yiyi said some off-topic remarks later on, these were also some of her expectations.
But this gave Chen Zhou a new inspiration.
That is the improvement of sensitivity. Can it be achieved specifically by increasing the number of detection instruments?
While Chen Zhou was thinking, Yang Yiyi said, "The glue ball detection method you want to find now is definitely different from the gravitational wave detection method."
After finishing speaking, Yang Yiyi paused for two seconds and continued: "But the glue ball detector, or high-energy physics experimental research, requires a particle accelerator, detector and other equipment."
"Accelerators accelerate tiny charged particles to very high energies, close to the speed of light, and then hit them on fixed targets or collide with each other to study the deep structure of matter."
"Detectors are used to detect tiny particles produced by collisions and record various information, which is essentially very different from gravitational wave detectors."
"But, how should I put it? The large-scale integrated multi-particle spectrometers currently used in fixed targets and colliders, as well as the large electronic detector arrays used in non-accelerator cosmic ray experiments, may still be able to find some similarities in gravitational wave detectors..."
Yang Yiyi didn't say it in an absolute way, but she didn't completely deny it either.
Compared to the fact that she had no idea about the difficult problem in the field of algebraic geometry, she still had some opinions on the glue ball experiment, which was also a physics observation experiment.
Hearing Yang Yiyi's words, Chen Zhou nodded and said softly: "I flipped through a document that was about the introduction and comparison of various detection instruments in the current physics community. The content was also the most basic part..."
Having said this, Chen Zhou suddenly stopped talking.
Because he suddenly thought of something.
