From Almighty Scholar to Chief Scientist

Chapter 197 Solve the 'noise'!chaotic system
"Sterling, send me all the particle trajectories for the past ten years."

In a spacious research room, computers are filled here, and hundreds of researchers are conducting their own research.

Lin Xiao, who was seated at the top, called out to a researcher below.

This researcher is an assistant staff assigned to him by CERN, of course it is not just this one, but a team of nine people, these nine people are responsible for meeting Lin Xiaoping's needs in project research, such as some of the research he arranged The research task also includes some of his life needs, such as needing to buy something, running errands and so on.

Of course, they are all very happy to be Lin Xiao's subordinates. After all, who doesn't regard Lin Xiao as their idol now?Especially these researchers are basically relatively young.

Soon, the researcher named Sterling replied: "Okay!"

Then Lin Xiao turned his attention to the computer, and soon, he received files one by one, and then he imported these files into the Geant4 Monte Carlo simulation software, and a three-dimensional image appeared on it, with a particle in it .

Press the simulate button next to it to see what these particles look like after they collide.

These data come from the data of every collision since the LHC was built.

In the past ten years, there have been a total of hundreds of millions of collisions, and the data they have brought is quite rich.

However, when Lin Xiao looked at these things, although they looked a bit messy, the fragmentation after the particle collision made the situation more complicated, but under his 4.95% brain development, these complex, It doesn't seem to be complicated.

Through these images, he can directly build their collision function in his mind.

According to the available data, the hundreds of millions of collisions produced very few W bosons, estimated to be only hundreds of thousands or even tens of thousands.

In addition, it is difficult for them to observe the W boson, so the few W bosons produced have brought many obstacles to their measurement of the quality of the W boson.

"In the past, the mass of the W boson could only be deduced from the decay products of the W boson, which would definitely lead to greater inaccuracy, but what if the W boson could be screened out directly?"

Lin Xiao thought about it.

W bosons decay very fast, and they can disappear in about one trillionth of a second after they are produced, which is the main reason why they are difficult to observe, but if they can really capture W bosons in a large The trajectory and the energy region it is in will be of great help to them in measuring the mass of the W boson.

Or should I say, decisive help.

From the measurement of the product of the W boson, it is inevitable to cause errors.

The reason why other particles do not have this kind of problem is that other particles exist for a longer time, even if it is one billionth of a second, it is still longer than the W boson's one trillionth of a second. Ten thousand times longer, plus the speed of these particles is quite fast, even a billionth of a second can fly a long trajectory, allowing them to observe.

"Actually, it's not impossible to find it."

Lin Xiao frowned slightly as he looked at the various trajectory lines on the screen.

There are many very short trajectory lines, maybe one of them is the line of W boson.

And besides that, there are more short traces, which come from all kinds of 'noise'.

For example, the influence of various electromagnetic waves, the noise of these wireless electromagnetic waves, will bring a lot of "noise" to their experimental data, electromagnetic waves have energy, when they are invisible, they are received by various sensors of the particle collider , these seemingly inexplicable trajectories and energy waves will be displayed on the computer.

This is why the LHC is built underground, but even if it is built underground, there will still be some headaches in the face of those invisible and invisible electromagnetic waves, and the influence of the earth's magnetic field cannot be ignored.

In addition, there may also be some impurity particles in the orbit of the particle collider, such as various molecules in the air. When we want to collide protons and antiprotons, they may collide with a Nitrogen molecules, and then lead to some inexplicable things in the final output data. After all, it is impossible to create a perfect vacuum environment on the earth.

In addition, the thermal radiation generated by the temperature of the surrounding environment, which is also a kind of electromagnetic wave, will also affect the accuracy of the measurement.

Therefore, there are so many interferences that affect the accuracy of the experiment, so some scientists proposed the idea of ​​building a particle collider on the moon, because the moon does not have as many electromagnetic waves as the earth, and the moon does not have a planetary magnetic field to speak of. Even the gravity is not as strong as that of the earth, coupled with the low temperature and vacuum environment, of course it is the most ideal place to build a particle collider.

However, building a particle collider on the moon is obviously not something they can consider now.

For Lin Xiao, he now has a three-step plan in his mind.

The first step is to find a way to deal with all kinds of 'noise'.

The second step is to establish the trajectory function and wave function of the W boson, and then input them into the software, so that the software can help find the matching trajectory and energy peak.

The third step is to determine its mass according to the traces of these directly found W bosons!

Thinking of this, Lin Xiao's eyes were determined.

feasible!

Then start with various radio electromagnetic waves.

Then he shouted: "Sterling, help me check the electromagnetic bands of all nearby signal towers."

Sterling, who was sitting across from him, asked, "Why are you checking this?"

"I want to get rid of the noise of these electromagnetic waves first."

Lin Xiao replied.

But hearing Lin Xiao's words, everyone present was a little surprised.

Solve the noise problem?

Of course, they have all thought about this issue, and have done it in the past, such as various optimizations in terms of algorithms and data processing, and they almost didn't install a Faraday cage here, but they can The degree to which it can be achieved is still limited. After all, this is already a problem in the field of chaotic systems. It cannot be said that it is difficult to deal with this problem, but it can only be said that it is very difficult.

As a result, Lin Xiao now actually said that he wanted to solve this problem?
"Are you sure?"

Sterling couldn't help asking.

"Sure." Lin Xiao nodded and said with a smile, "Don't you think these 'noises' are really annoying?"

It is indeed annoying that the people present look at each other in blank dismay, but what should we do?
They can't solve it, so they can only endure it for a while.

The experimental results they made before basically have a confidence interval, just like the results they measure now, there will be an interval of plus or minus standard deviation.

And these wireless electromagnetic waves can provide a lot of range for these intervals.

However, thinking about Lin Xiao's mathematical ability, none of them may have the qualifications to deny that he has this ability.

Then we can only hope that Lin Xiao can do it.

And if Lin Xiao can really do it, not to mention the help it will bring to their research, it will even be of great help to the researchers of particle accelerators all over the world, because it means that they will be able to better understand these 'noises'. treatment, so that their research has a more 'quiet' environment.

So, unconsciously, everyone began to look forward to it.

However, what none of them expected was that what Lin Xiao wanted to solve was not only wireless electromagnetic waves, but also the effects of impurity particles, environmental thermal radiation, and even the geomagnetic field!

Lin Xiao didn't plan to tell them about such things, and let them be pleasantly surprised later.

……

Time passes quickly.

In Lin Xiao's residence.

The dormitory that CERN arranged for him was different from the dormitory at the Ecole Normale Supérieure in Paris. It was a small villa with a nice view, and it was quite close to the nearby cities. It took only ten minutes to drive there.

At this time, he was working at his desk in the study.

What he studied was, of course, a solution for dealing with wireless electromagnetic waves.

So far, he has achieved certain results.

For this chaotic system, one thing is clear, these chaos are not chaotic to the truth of the real universe.

Here, we can introduce the concept of Laplace’s demon to understand. Of course, it must be an evolved version of Laplace’s demon, which must understand quantum mechanics and relativity.

As long as we can know the situation of each thing in this chaotic system, we can use various theories to determine their future situation.

Of course, for the current situation, it is too early to want to develop this modern version of Laplace's demon.

As for the chaotic system that Lin Xiao deals with, one thing is certain, that is, these chaotic things are all electromagnetic waves.

This same essence allows him to find a way to deal with them.

"However, difficulties still exist."

Lin Xiao frowned slightly, looking at an extremely complicated formula that he wrote down.

For this situation, he needs to think of a way to handle it better.

However, at this moment, his phone rang suddenly.

Glancing at the caller, it was a girl among the nine researchers under him, named Elizabeth Marcia, British.

Although the United Kingdom has left the European Union, it does not affect the British working at CERN. This Elizabeth Marcia herself also graduated from the Department of Physics of Cambridge University, which is also a graduate of a famous school.

Lin Xiao answered the phone and said, "Marcia, what's the matter?"

"Lin! The collision track of the first area is measured according to the distance of the wall radius. Shall I send it to you now?"

"Okay, send it to me."

Lin Xiao said.

"Okay! Oh, by the way, Nigel Lockyer, the director of Fermilab in the United States, and several old men, they all came here and said they wanted to meet you. Do you want me to pick you up to the headquarters now?"

"Old man? Don't let them know what you said." Lin Xiao couldn't help laughing, and then asked: "However, why did the people from Fermilab come to see me suddenly?"

"Probably came to spy on the military situation."

Elizabeth Marcia replied.

Lin Xiao asked puzzledly, "Spying on the military situation? Why?"

"Fermilab is also working on a project to measure the mass of the W boson, and we are considered competitors."

"Is that so?" Lin Xiao understood, and then said, "If it's convenient for you, please come and pick me up."

"Okay! I'll be right there!"

Soon the phone was hung up, and after a while, Lin Xiao heard the doorbell ring. He packed up his things, went to the door and opened it, and a blond British girl appeared in front of him.

"Mr. Lin!"

Lin Xiao smiled at her, "Marcia."

"It's all said, you call me Elizabeth, don't call me Marcia."

"All the same, all the same."

Lin Xiao smiled and said, "Okay, let's go now."

……

　Exam subject [-] in the morning, I came back a little late, and sent it late, sorry.
