Chapter 378 She Said She Had Never Been Here (6092)

Fang Yu did have to go to Los Santos because his summer job was over, paying $22 an hour.

“Initial electron beam energy: 80 MeV;

“Plasma density: 10.1×10 to the power of /cubic centimeter;

“Peak coda amplitude: 1.8 GeV/m, lower than the expected value of 2.5 GeV/m;

“Electron beam energy gain: 1.2 times, lower than the expected gain rate of 1.5 times;
"Trajectory deviation: No obvious abnormality, consistent with theoretical calculations."

……

"Huh, it didn't work. It's probably because the plasma density is different from the target value, or the multi-channel detector has a high-frequency false signal when collecting data, resulting in inaccurate data."

Kevin Stone took off his goggles and sighed, a little frustrated but not too frustrated.

He has conducted this experiment entitled "Resonant Behavior of High-Density Plasma Wakefield on High-Energy Electron Beam" three times, and all three times were unsuccessful.

As the junior boss of Jay Hauser's group, he was qualified to apply for ETPD to conduct experiments, but obviously he needed to make an appointment.

Every time, he had to make an appointment more than a month in advance and then wait in line for more than a month, which took two months all in all.

In other words, he had been doing this experiment for half a year, but had not achieved anything.

Fang Yu pushed the plain glasses on his nose and said, "Kevin, can you let me see the report? I want to learn from it."

Kevin Stone shrugged. "It's useless for you to read it. No matter how high your IQ is, if you haven't read a lot of papers, this stuff will be like a mystery to you. It won't be of any use to you in learning."

Having said that, Kevin Stone still asked the researcher to turn the computer screen to face Fang Yu.

Within two days of working as a laborer in Jay Hauser's research group, Fang Yu successfully colluded with Kevin Stone, the junior boss under Jay Hauser, and became Kevin Stone's laboratory assistant in the name of a summer internship.

Kevin Stone is an experimental physicist, specifically in the field of high-energy particle physics experiments.

There was no other reason why Fang Yu approached Kevin Stone except that he had the authority to use EPTD to conduct experiments, and his experiment schedule was about to expire.

Only by actually operating ETPD can we have a more intuitive understanding of ETPD and solve some engineering problems in the design plan of Yuzi.

Theoretical things are easy to deal with, but in engineering, many things have to rely on the engineers' on-site ideas and inspiration to solve them. They will not appear in data documents, and the Orange Model naturally has no way of knowing them.

Therefore, if Fang Yu wants to create his own tokamak, or even make his own miniaturized tokamak or stellarator, on-site observation and operation are essential.

"That's because you've never seen a true genius, Kevin. Don't use your IQ of 140 to speculate on a genius like me who's 175."

Fang Yu took the mouse from the researcher without any hesitation and said something to Kevin Stone.

When he joined the group, Kevin Stone tested Fang Yu's IQ according to the practice within Jay Hauser's group, and the result was a terrifying 175!

Previously, the person with the highest IQ around Jay Hauser was the head of another group, Yahya Minadev, whose IQ was 160.

People have different personalities, so Fang Yu’s way of getting along with them will also be different.

Kevin Stone is a typical INFJ. Although he seems introverted, he is more eager to establish a deeper emotional connection with others and likes to build interpersonal relationships by helping others.
At the same time, they are more tolerant of harmless ridicule and jokes from others, and may even think that this is a sign of good relations between the two parties.

Of course, jokes should have limits. Fang Yu said in a joking tone, "Don't speculate on a genius like me with your IQ of 140." This just happened to hit the boundary of Kevin Stone's tolerance, making it easier for Kevin Stone to interact with him.

But if Fang Yu added, "The IQ difference between humans and dogs is only 40, so I think your view of dogs is similar to that of ordinary people."

That would go beyond Kevin Stone's acceptable boundaries and would affect the relationship.

The grasp of this scale lies in one's heart, and different scales need to be adjusted according to different people.

Fang Yu flipped through the report on the screen and passed the data to Youzi for analysis.

"Keith, would you like some coffee? I just got some from Tomo. Oh, and they have the best sweet potato pretzels."

Emily Castillo knocked on the open laboratory door and entered without being invited, carrying two cups of coffee.

Kevin Stone looked at Fang Yu with envy. Ever since this guy joined their team a few days ago, Emily would find excuses to come over twice a day.

Sometimes when Fang Yu was not around, Emily would just turn around and leave.

As you can imagine, I still don’t have my share of coffee today.

Fang Yu stared at the screen intently: "Thank you, just leave it there."

Judging from the experimental results, the predictions made at the beginning of the experiment were not fully verified. Although the energy increased to a certain extent, it was far from what Kevin Stone had calculated before. This kind of data error cannot be used as data in the paper at all.

According to theoretical model predictions, the wake field should exhibit higher amplitude at the target plasma density and effectively increase the energy of the electron beam.

However, the experimental data failed to verify this hypothesis, and the amplitude of the wake field and the energy gain of the electron beam were significantly lower than expected.

Therefore, the experiment may indeed have failed.

Huh?and many more.

Fang Yu flipped through two pages of the data sheet and looked at the oscilloscope graph at the back, and suddenly felt something was wrong.

"Kevin, why is there no spectrum graph and heat map for this part of the data? Ma Wei, can you generate it?" Fang Yu said to Zhou Yi, who looked to be at least thirty or forty years old and was sitting in front of the computer.

The proportion of Zhou people in UCLA is too high. Apart from temporary workers like Fang Yu, there are 25 Zhou people in Jay Hauser's 6-person research group, including formal doctoral and postdoctoral researchers. Ma Wei is one of them.

Spectrum graphs and heat maps are key tools for analyzing oscillation signals. Generally speaking, they have been processed in the experiment. It is estimated that Ma Wei, who was responsible for data analysis, missed it, and Kevin Stone did not pay close attention to it when he saw that the experiment failed.

Ma Wei slapped his bald forehead and said, "Mine."

Ma Wei looks like he is forty, but in fact he just looks old and is only twenty-six this year.

In fact, he looked like this when he was sixteen.

It’s no wonder that his appearance has stood the test of time. I guess he will still look the same in another twenty years.

Because his dad is like this, and he and his dad look like brothers when they stand together.

When he was in high school, he went to a classmate's house to play. When he arrived at his classmate's house, his classmate's parents thought it was the teacher who came to visit.

Ma Wei quickly operated the data analysis software, regenerated the spectrum graph and heat map, and turned the display screen to Fang Yu.

Fang Yu read it carefully.

"Kevin, during the decay period of the wake field, in the detection data at time node t=4.2ps, the multi-channel detector recorded a set of high-frequency oscillation signals with a frequency of about 12.6 THz. The frequency seems to have a certain periodicity, which does not seem to have anything to do with the plasma density."

Kevin Stone came over to take a closer look: "Cyclic? Where?"

Fang Yu asked Ma Wei to put the spectrum map and the heat map together: "Combined with the time correlation of the heat map, the spectrum components obtained by Fourier transform show that this 12.6 THz high-frequency signal is enhanced once every 1.2 ps, and the density does not seem to have a direct effect on its intensity."

Kevin Stone wondered: "Fourier transform analysis? Where does the Fourier transform analysis of this signal come from?"

"Of course it's mental arithmetic." Fang Yu said shamelessly.

Kevin almost vomited blood.

Mental Fourier Transform? Bragging, right?

The frequency of 12.6 Thz corresponds to a period of 80 fs. It is impossible to do mental arithmetic or even manual arithmetic. Fast Fourier transform can only be done by computer. This is common sense!
Emily's eyes were filled with love. Gus was so handsome that he could do Fourier arithmetic in his mind.

What did you say? Mental arithmetic is impossible? Whatever Giss says is right!
Fang Yu grinned: "Of course it's impossible to use Fourier transform to do mental arithmetic, but the signal period is 1.2 ps, and we can directly use f=1/T to get 12.6 THz. As long as you are familiar with the nature of Fourier transform, you don't need such complicated calculations. The data is here, but you just can't see it. I think the final result after Fourier transform calculation should be the same."

That’s more like it, Kevin nodded, but then he thought, it’s far from it! ?

This requires a deep understanding and mastery of Fourier transform! ? The periodic signal is not clear at all. Are you calculating Fourier by estimation?
It must be bragging.

"It is indeed 12.6 Thz." Ma Wei promptly re-presented on the screen the result obtained after Fourier transform of the frequency signal with a period of 1.2 ps.

Ma Wei couldn't help but look at Fang Yu as if he were a monster.

This is hundreds of thousands of rows of data. How did he find this signal among so many rows? And he also saw the periodicity in it at a glance?
If the periodicity is clear, that would be fine, but it’s not clear at all.

Is it possible for an average person to find patterns from so much data?

Is it possible that there really is such a genius in the world?
Shouldn't people like this be as ignorant and low in emotional intelligence as Sheldon?

How could it be that a second-generation rich undergraduate student, who had only been in the group for a few days, had become friends with everyone and even dared to confront the small boss?

I lived in the penthouse apartment No. 19 which was over square feet. I held three parties in the five days since I joined the crew.

Participants included fashion icons from the School of Theater, Film and Television and the School of Art and Architecture.

We even saw last year's UCLA prom queen, Erin Caldwell from the history department, and Chen Siyu, the internet celebrity daughter of Yingzhou's cram school queen, who was attending classes at UCLA to prepare for the UCLA psychology graduate school entrance exam.

Is this the difference between a small town test-taker and a rich second-generation ABC?

Kevin was stunned when he heard Ma Wei's reply.

Fang Yu felt like she was floating in the air.

Emily squeezed her legs together.

It feels so good to show off in front of others.

"It should be a high-frequency false signal in the multi-channel detector. This signal does not appear in the theoretical model and has no direct correlation with the amplitude of the coda wave. It should not affect the main conclusions of the experiment... right..."

Kevin stared at the screen and was about to make a judgment, but subconsciously looked at Fang Yu.

Fang Yu also frowned. "Gis, is there any important discovery?" Emily came to Fang Yu, leaned on the table with one hand, crossed her legs slightly, and stood upright without leaving any trace, licking the milk foam on her lips.

Ah~ Boys who focus on scientific research are indeed the most attractive~
Emily seemed to have forgotten that 80% of the boys around her were focused on scientific research.

Fang Yu's mind was not on her at all. He just shook his head, his eyes still fixed on the screen.

The vibration frequency of this signal is very, very familiar, but I just can't remember where I have seen it.

I'm not a physics major, and 90% of my knowledge is second-hand knowledge passed on to me by Yuzi. The most recent physics experiment I did before was when I was in my second year of high school, when I measured electromotive force and internal resistance. I've never been exposed to high-energy physics before, so how could I feel familiar with it?
"Yuzi, did you find anything?" Fang Yu asked Yuzi.

"Not yet, but there was a problem with Kevin Stone's experimental design, so I optimized it for him." Yuzu said casually.

Fang Yu frowned: "Have you found this 12.5 Thz signal?"

Yuzu was stunned for a moment: "It should be a false signal from the instrument? I don't find any practical significance in this set of data."

Fang Yu looked at the icon on the screen suspiciously again.

Is it really a false signal from the instrument?
Since even Yuzu didn't notice the problem, maybe I was just overthinking it.

"Alright, although the experiment was not successful, it did initially verify the resonance problem. However, the credibility of the data is not high. I think that next time if we can control the plasma density accuracy within a 1% error range, we should be able to get valid data."

Kevin Stone sighed, patted Fang Yu and Ma Wei on the shoulders, comforted the team members and boosted team morale.

Ma Wei's expression relaxed. It was a low-level oversight that he did not take out the spectrum diagram and heat map immediately today. He was still a little nervous, but when he saw Kevin Stone did not say anything, he finally breathed a sigh of relief.

"There's no hope next time. Didn't you notice that there's something wrong with the design of the experimental plan?" Fang Yu said casually while taking off his protective suit.

"Impossible!" Kevin Stone's face changed and became stern.

When it comes to Kevin's professional field, he is not so nice.

No matter how talented you are, experimental physics is my field!
You actually question me in my field! ?

Fang Yu shrugged nonchalantly: "There are indeed some problems with the density accuracy of the plasma, but it is not caused by the control accuracy of the closed-loop control system as you think. Instead of wasting a lot of energy on the dynamic adjustment of the feedback loop, it is better to focus on the design of the plasma generation chamber."

At this point, Fang Yu paused: "For example... add a turbulence suppressor."

These words were like a bolt of lightning, striking Kevin Stone on the head.

"Turbulence?!" Kevin Stone suddenly understood.

"That's right! It's turbulence! I didn't even realize the problem of turbulence! This is not a problem of control accuracy! It's a local density fluctuation!"

"Damn it! I wasted four months of my time! I have to reapply for ETPD again! It will take another month!"

"No, I need to call the professor and ask him to give me priority!"

Kevin Stone regretted for a long time, then turned around and saw that Fang Yu had already taken off his protective suit and was packing his bag, ready to leave.

"Gis, how did you come up with that!?"

Kevin has officially entered the pretentious background character template of "unbelievable", "shocked", "horrified", and "shocked".

Fang Yu's face was calm, as if he was just stating an ordinary fact: "Because I'm a genius."

Go go go go!
Kevin Stone instantly understood Leonard's mentality in The Big Bang Theory.

No, Leonard has the blonde girl Penny, but my girlfriend is a female doctor who refuses to use shampoo when washing her hair!

"Okay, by the way, everyone is here today, let's go have a small gathering, should we go to Tacos Tu or Sushi Stop? Emily, do you have time? Do you want to go?"

Kevin calmed down. Even though Fang Yu had dealt him a heavy blow today, he had finally found the problem with the experiment. Next time, after solving the turbulence problem, he believed that he would be able to produce data that would satisfy him!

"I have time!" Emily immediately jumped down from the test bench.

"I don't have time, so I won't go." Fang Yu put on his bag and shook the car keys in his hand. "I have an appointment with a few friends. They want to treat me to an authentic Zhou meal. I wish you have a good time."

"Gis! Wait a minute!" Emily was anxious and smoothed her hair. "Authentic Zhou restaurant? I'm also interested. Is it convenient for me to go with you?"

"It's not convenient. My girlfriend is going too."

When dealing with people who are not interested in him, Fang Yu is always decisive and does not leave any room for the other party to imagine.

"That is to say, it would be convenient if your girlfriend doesn't go~" Emily persisted.

Oh my god, why don’t you play by the rules?

Fang Yu waved silently, turned and left.

"Um... uh, Emily, are you still going?" Kevin Stone asked cautiously, looking at Emily's determined expression.

"No!" Emily kicked Kevin Stone hard.
-
"Old Fang! Here, it's right under the Shudu Impression sign! Do you see it!?" Huang Xiang waved at Fang Yu from a distance.

Fang Yu was wearing a loose white T-shirt of a trendy brand, a red Angels cap, and sunglasses. He easily saw the 404 trio across the street.

The three adopted sons were not very noticeable, but there were not many people in this place.

"I say, you three are really stingy. I came all the way to Rowland Heights, and you just treat me to this?" Fang Yu curled his lips and pointed at the sign of Shudu Impression.

Rowland Heights is an unincorporated community in Los Santos County. In fact, it is no longer within the city of Los Santos. Previously, most of the people here were descendants of the Zhou Dynasty who immigrated from Yingzhou more than 30 years ago. However, in the past two years, wealthy people from the inland of the Great Zhou have also begun to settle here in large numbers, and their numbers have long exceeded those of the original immigrants.

Therefore, the weekly meals here are considered the most authentic in the Greater Los Santos area. Although high-end restaurants still focus on Cantonese cuisine and roast duck, there are also many restaurants serving other cuisines.

The Shudu Impression chosen by the three adopted sons is a Sichuan cuisine as its name suggests. The average price per person is about 30 yuan, which is expensive in the Da Zhou, but it is cheap here.

What's more, the environment is not that good either, and it looks only slightly better than the fly restaurants in China.

"Old Fang, you are a full man who doesn't know the hunger of a hungry man. You just came here, but we have been here for almost half a month. We are almost vomiting from eating hamburgers and steaks every day. Didn't you see that Old Huang is holding two large bags of instant noodles? We just bought them at Zhouren Supermarket!"

As soon as Luo Ziming saw Fang Yu, he started to complain bitterly, completely unaware that Fang Yu had just said he had come all the way to Rowland Heights, not all the way to Miami.

"Don't disbelieve me. If I leave you in this hellhole for half a month, I guarantee you'll want instant noodles more than we do!" Huang Xiang looked extremely hungry. "I told them two days ago that when I travel around the world, I will definitely bring enough instant noodles and pickles with me."

Fang Yu chuckled and said, "Sorry, I can teleport. Let alone staying here for half a month, even if I stay for three years, I will still eat hot pot if I want to, and eat skewers if I want to."

Several people entered the restaurant one after another. Lu Xuechang boasted to Fang Yu, "This restaurant is small, but we checked and found that this is the most authentic Sichuan cuisine in Los Santos. Many big stars have been here."

"Like Uncle Ge, Huang Xiaoming, Zhao Dayan, and Da Mimi..."

"Let's talk later. I have a call." As Fang Yu was speaking, his phone rang.

After answering the call, Fang Yu chatted for a while, then sent the location to the person on the other end of the phone via WeChat, and asked casually, "Hey? I heard that you've been to this store before? But I don't know where it is?"

"Never been here? Oh, okay, how long? Fifty minutes? Fine, then we won't wait for you, let's eat first."

"Okay, I get it. We'll definitely need a private room. Don't worry."

"Old Lu, go on, who else has come?" After hanging up the phone, Fang Yu asked while sending a WeChat message.

"Eh? By the way, you said before that you would come with a friend. Who is it?" Lu Xuechang rolled his eyes and asked tentatively.

"Oh, Da Mimi." Fang Yu looked normal. "I just asked her, and she said she had never been here."

The three of them fell silent instantly, and then a few seconds passed.

“Pfft!!!! Hahahahahaha!”

Luo Ziming laughed so hard that his pants almost fell off.

There is no way. I haven’t eaten well these days, and my pants waist has become an inch smaller due to hunger.

"Old Fang, you are such a boaster. You said that Da Mimi will come here to see you soon?"

Fang Yu looked calm: "It's not just Da Mimi, there's also Scarlett."

"Who?" The trio were confused, and Luo Ziming asked with a question mark on his face.

"Scarlett Johansson, Black Widow."

“Pfft!!! Hahahahahahahahaha!!!” The trio once again got the script of pretending to be cool but getting slapped in the face.

Huang Xiang shook his head vigorously. “If you said you knew Da Mimi, I would believe you. It’s normal for a second-generation rich like you to know celebrities. But you said Black Widow is coming too? Hahahahahaha.”

"If Black Widow comes, Lao Fang, have you seen this can of chili peppers? I'll eat them all right there!"

Luo Ziming pointed at the chili peppers on the table and swore a poisonous oath despite Py's protest.

"Boss! Bring me five packs of tissues!" Fang Yu ignored him and waved to the boss for tissues.

"Why order so many tissues? What a waste! They cost one yuan a pack." Luo Ziming looked pained.

Fang Yu said calmly: "Don't feel bad, it's from your body anyway."

"When your hemorrhoids burst, you'll need this to stop the bleeding... Oh my god, a small pack? No, boss! Give me ten more packs!"

It’s over. If you don’t make it before 12 o’clock, the guaranteed reward will be gone.
