Chapter 378 She Said She Hadn’t Been Here (6092)
Fang Yu really had to go to Los Santos because his summer job was up, paying $22 an hour.
“Initial electron beam energy: 80 MeV;
“Plasma density: 10.1×1020/cm3;
“The peak amplitude of the coda wave is 1.8 GeV/m, which is 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 anomalies, 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 during data acquisition, resulting in inaccurate data."
Kevin Stone took off his goggles and sighed, feeling a little frustrated but not too frustrated.
He has conducted this experiment called "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 is qualified to apply for ETPD to conduct experiments, but obviously he needs 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 in total.
In other words, he had been doing this experiment for half a year, but hadn't achieved anything.
Fang Yu pushed the plain glasses on the bridge of 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 look like a mystery to you. It won't be of any use to you."
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, Jay Hauser's subordinate, 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.
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 arrive.
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 cannot know them.
Therefore, if Fang Yu wants to create his own tokamak, or even 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 judge a genius like me who's 175."
Fang Yu took the mouse from the researcher without any hesitation and casually said something to Kevin Stone.
When joining 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 Houser was the leader of another group, Yahya Mina Dev, 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 desires 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 other people's harmless ridicule and jokes, and may even think that this is a sign of a good relationship between the two parties.
Of course, jokes should have limits. Fang Yu said in a joking tone that with your IQ of 140, don't speculate on a genius like me. This just happened to hit the limit of Kevin Stone's tolerance, making it easier for Kevin Stone to communicate with each other.
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, carrying two cups of coffee, and entered without being invited.
Kevin Stone looked at Fang Yu with envy. Ever since this guy joined their group 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, there is still no coffee for me 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 indeed not fully verified. Although there was a certain increase in energy, it was far from what Kevin Stone had calculated before. This data error could not 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? Wait.
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 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 only formal doctoral and postdoctoral researchers, and there are 6 Zhou people in Jay Hauser's 25-person research group, and 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 actually he just looks old. He 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 father looks like this, and he and his father look like brothers when they stand together.
When he was in high school, he went to his 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 of the wake field, at time t = 4.2 ps, the multi-channel detector recorded a set of high-frequency oscillation signals at approximately 12.6 THz. The frequency appears to have a certain periodicity, which does not seem to be related to the plasma density."
Kevin Stone leaned over to take a closer look: "Cyclic? Where?"
Fang Yu asked Ma Wei to put the spectrum map and heat map together. "Combined with the time correlation of the heat map and the spectrum components obtained through Fourier transform, we can see 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.
Mentally calculating Fourier transforms? Bragging, huh?
The frequency of 12.6 Thz corresponds to a period of 80 fs. Not to mention mental arithmetic, even manual arithmetic is impossible. 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 calculations in his mind.
What did you say? Mental arithmetic is impossible? Everything Giss says is right!
Fang Yu grinned. "Of course, it's impossible to do mental math using Fourier transforms, but the signal period is 1.2 ps. Simply using f=1/T gives us 12.6 THz. As long as you're familiar with the nature of Fourier transforms, you don't need such complex calculations. The data is right here, you just can't see it. I think the final Fourier transform calculation will give the same result."
That’s more like it, Kevin nodded, but then he thought, it’s far from it! ?
This requires a deep understanding and mastery of the Fourier transform! The periodic signal is not clear at all. Are you calculating the Fourier transform by estimation?
It must be bragging.
"It is indeed 12.6 Thz." Ma Wei timely re-presented the result obtained after Fourier transform of the frequency signal with a period of 1.2 ps on the screen.
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 in such a large amount of data? And even see the periodicity in it at a glance?
If the periodicity is clear, that would be fine, but it is not clear at all.
Is it possible for an average person to find patterns from so much data?
Is there really such a genius in the world?
Shouldn't people like this be as clueless and low in emotional intelligence as Sheldon?
How could it be that a rich second-generation 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 8,000 square feet. I held three parties in the five days since I joined the crew.
Even fashionistas from the School of Theater, Film and Television and the School of Art and Architecture attended.
We even saw last year's UCLA prom queen, Erin Caldwell from the History Department, and Chen Siyu, the internet-famous daughter of Yingzhou's cram school queen, who was attending classes at UCLA and preparing for the UCLA psychology graduate 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 desperately.
It feels so good to show off in front of others.
"It's probably a high-frequency spurious signal in the multi-channel detector. This signal doesn't appear in the theoretical model, and it has no direct correlation with the amplitude of the coda wave. It shouldn't 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.
"Geez, is there any important discovery?" Emily came close 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 the corner of her mouth.
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've seen it before.
I'm not a physics major, and 90% of my knowledge is second-hand knowledge passed down by Yuzi. The last 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 had never been exposed to high-energy physics before, so how could I feel familiar with it?
"Yuzi, have you found 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 discovered this 12.5 Thz signal?"
Yuzu was stunned for a moment. "It must be a false signal from the instrument, right? I don't see any practical significance in this data."
Fang Yu looked at the icon on the screen again suspiciously.
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 wasn't successful, it did provide preliminary verification of the resonance problem. However, the data isn't very reliable. I think if we can control the plasma density accuracy within a 1% error range next time, we should be able to get valid data."
Kevin Stone sighed and patted Fang Yu and Ma Wei on the shoulders to comfort the team members and boost team morale.
Ma Wei's expression relaxed. It was a low-level oversight that he didn't take out the spectrum diagram and heat map right away. He was still a little nervous, but when he saw that Kevin Stone didn't 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 issues with the plasma density accuracy, but it's 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's 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 it was a turbulence problem! It's not a control accuracy problem! It's a local density fluctuation!"
"Damn it! Four months wasted! I have to reapply for ETPD again! It will take another month!"
"No, I'm going to call the professor and ask him to give me priority!"
Kevin Stone regretted it 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, what did you come up with!?"
Kevin has officially entered the pretentious background character template of "incredible", "shocked", "horrified", and "shocked".
Fang Yu's face was calm, as if he was simply stating a mundane 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's here today, let's go get together. Should we go to Tacos Tu or Sushi Stop? Emily, do you have time? Do you want to go?"
Kevin calmed down. Although Fang Yu had hit him hard 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 some friends. They want to treat me to an authentic Zhou meal. I hope you have a good time."
"Gis! Wait a minute!" Emily frantically smoothed her hair. "Authentic Zhou cuisine? I'm interested too. Can I go with you?"
"It's inconvenient. My girlfriend is going too."
Fang Yu is always decisive and decisive when dealing with people who are not interested in him, leaving them no room for imagination.
"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 and turned away.
"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, 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 hat, 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 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 Zhou descendants who immigrated from Yingzhou more than 30 years ago. However, in the past two years, wealthy people from the inland of Da Zhou have also begun to settle here in large numbers, and their number has long exceeded that 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 the name suggests. The average price per person is about 30 yuan, which is expensive in the Da Zhou Dynasty, but it is cheap here.
Moreover, the environment is not very good, and it looks only slightly better than the fly restaurants in China.
"Old Fang, you're a full man who doesn't know the hunger of a hungry man. You just got here, but we've been here for almost half a month. We've been eating hamburgers and steaks every day and are almost throwing up. Didn't you see Old Huang holding two big bags of instant noodles? We just bought those at Zhouren Supermarket!"
As soon as Luo Ziming saw Fang Yu, he started complaining, 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 crave instant noodles even more than we do!" Huang Xiang said, his eyes bulging with hunger. "I told them a few days ago that when I travel around the world, I'll definitely bring plenty of instant noodles and pickles."
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 want to eat hot pot and eat skewers."
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 picking up the phone, Fang Yu chatted for a few minutes, then sent the location to the person on the other end of the phone via WeChat. Then he casually asked, "Hey? I heard you've been to this store before? I don't know where it is yet?"
"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 hasn't been here."
The three of them fell silent instantly, and then a few seconds passed.
“Pfft!!!! Hahahahahahaha!”
Luo Ziming laughed so hard that his pants almost fell off.
There's no way. I haven't eaten well these days and my pants waist has become an inch smaller due to hunger.
"Old Fang, you're such a boaster. You said Da Mimi would come here to see you soon?"
Fang Yu's expression remained calm: "It's not just Da Mimi, there's also Scarlett."
"Who?" The trio was confused, and Luo Ziming asked with a question mark on his face.
"Black Widow, Scarlett Johansson."
"Pfft!!! Hahahahahahahahaha!!!" The trio once again received the script of pretending to be cool but then getting slapped in the face.
Huang Xiang shook his head fiercely. "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 here!"
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, asking for tissues.
"Why order so many tissues? What a waste! They cost one yuan a pack." Luo Ziming looked pained.
Fang Yu was calm and composed: "Don't feel bad, it's from your body anyway."
"Your hemorrhoids will burst later, and you'll need this to stop the bleeding... Oh my god, small packets? No, boss! Give me ten more!"
It’s over. If I don’t make it before 12 o’clock, the guaranteed reward will be gone.
Woo woo woo.
