Chapter 25: Structural Equations***
"Gravity...... Slowing down time? Ji Wanxing repeated with some stumbling, "This idea, uh...... It's kind of weird. Aren't we always in a gravitational field? ”
"So our timer is slower than the satellite?" An Chen casually followed this logic and said, "The less gravity there is, the faster time will be—maybe so?" ”
"Ann...... An Chen," Ji Wanxing had to say, "if the assumption is that time itself has changed, then the question becomes ...... I can't study it at all. ”
"Not necessarily, at least we can make up the possible coefficients of this fitting equation first." An Chen unconsciously knocked on the table, "Quadratic equation...... If it is related to gravity, it makes sense that it is a quadratic equation. But how does a one-time term come about? What is the relationship between a quadratic term and a primary term? And if you look at this curve, it doesn't exactly match the data points. ”
"This is already ...... The supercomputing cluster took 24 hours to figure out the results. Ji Wanxing explained.
"Suppose that the source of the quadratic term is related to gravity, then what is the primary term?" An Chen said while thinking, "Maybe it has something to do with line speed?" ”
"How should this be calculated?" Ji Wanxing asked with some embarrassment. Her theoretical foundation is already relatively solid, but to do such a complex fit, even Ji Wanxing doesn't know how to use a supercomputer to achieve it.
An Chen patted her arm, not caring about this problem at all: "To make such a complex structure, if you can't calculate it with a computer, then you have to find Marina." It's better to go late than early, you come with me. ”
Ji Wanxing didn't know who An Chen was referring to Marina, but in her opinion, the people An Chen knew were very "cool". Therefore, despite being a little socially phobic, Ji Wanxing followed An Chen out of the main control room.
Taking the elevator down to the leisure platform on the 25th floor of the headquarters building, Anchen found the alternate Minister of Agriculture, Michelin Marina, in his personal 3D screening room.
"Sister Anchen!" Marina threw away her 3D glasses and threw herself at Anchen.
Anchen had to pick up Marina and give her a kiss on the cheek.
Ji Wanxing turned sideways without a trace, as if he had bumped into some private scene. However, in Anchen's opinion, Marina is just still childish. All adult α women know that they are not allowed to love the same sex, so if Marina really has that kind of heart for her, I am afraid it will be too late to avoid suspicion.
Putting Marina down, An Chen rubbed his cheek with his hand, rubbing off a faint layer of rose: "Hey, the lipstick I wore today is a little stained." ”
"Cut, the mirror lip gloss that people apply is originally moisturizing." Marina took An Chen's arm and said coquettishly.
"You eat so many osmanthus cakes, you don't have a 'mirror' for a long time, right?" An Chen quipped her.
To be honest, it was really hard for her to imagine that Marina would be twenty-four years old, and that she would marry the son of a certain family in a short time, and eventually actually take over the Michelin family and become the next Minister of Agriculture...... Time flies, in Anchen's memory, Marina is still the little girl in the pink tutu dress who followed Paanka fourteen years ago, and the scene she first saw seemed to have happened yesterday.
"It doesn't matter, as long as the color is still there. Sister Anchen, don't you see this color looking good? Marina took out a tubular object from her small satchel and shook it in front of Anchen.
"It's a nice color, too, but I still like the one you painted yesterday." An Chen commented, and then waved his hand to connect his smart bracelet to the display screen in the screening room, projecting Ji Wanxing's original data and calculation process, "I came to you today mainly to ask you to do me a favor." ”
"Oh, fit the curve and do the construction." Marina looked at it and immediately smiled, "Hey, that's kind of interesting. ”
"This is what I mentioned earlier, the status time difference effect." Anchen explained, "At the moment, my guess is that it has something to do with the gravitational pull of the earth. ”
"Gravity? I know, it's G, M, and R...... How many times has R come to the party? Marina asked, somewhat uncertain.
Ji Wanxing muttered in his heart, is this reliable? She doesn't want to judge people by their appearance, but a girl like Marina, who is delicately dressed and soft and cute, and has forgotten the formula of gravity, can she really help?
“GMm/r^2。” An Chen reminded her, "There is also an algorithm for the linear velocity of the track, GMm/r^2=Mmv^2/r." ”
"What's that?" Marina scratched at her curly light brown ponytail, "I've almost forgotten physics, you can write it down for me." ”
Ji Wanxing looked at An Chen with some hesitation, but An Chen naturally wrote these two calculations on the display screen with a capacitive pen.
Ji Wanxing finally couldn't help it, and said with some hesitation: "That...... This is preceded by the code that I used to calculate the fit curve—"
But was interrupted by Marina: "No, no, no, I don't even need to know about that." The fitting curve is the fitting curve, the original equation is the original equation, and I can't use the fitting algorithm. ”
This sounds a bit arrogant, Ji Wanxing silently took half a step back, and sighed a little that An Chen is not reliable all the time.
However, An Chen, who has really seen the "Michulin Miracle", is very confident in Marina: "That's okay, Marina, you count slowly, don't be in a hurry about this." ”
She pulled Ji Wanxing away, and after leaving the 3D screening room, Ji Wanxing couldn't help but ask, "Ann...... Anchen, can this friend of yours really construct the original equation? ”
"Don't worry, whether it's true or not, Marina can definitely construct something." An Chen waved his hand.
Ji Wanxing muttered in his heart, constructing a random one can be regarded as "constructing something". It is to put together the gravitational constant and the mass of the earth by an order of magnitude, and I am afraid that it can also be made up on the basis of quadratic equations. But An Chen seemed to trust her friend very much, and Ji Wanxing didn't say anything more.
"Wanxing, why don't we go to dinner first?" An Chen patted her shoulder and said.
"Good...... All right. Ji Wanxing nodded a little awkwardly.
Descending from the elevator to the 21st floor is the location of the second restaurant of the Imperial Shield headquarters. Restaurant No. 2 is a little different from Restaurant No. 3, which An Chen frequents, because it is close to the lower floors, and many of the people who come here are engineers working in the subtranssonic wind tunnel laboratory.
Only the part of the aerodynamic experiment of the aviation division of the Emperor Sky Shield Group is planned to be carried out at the headquarters, mainly because the aerospace division above also needs to use a wind tunnel when doing rocket out of the atmosphere experiment. Therefore, correspondingly, the wind tunnel laboratory is also relatively busy, and the engineers working there are more anxious than the people on the upper floors, and they are in groups when eating, grabbing and eating quickly, so An Chen is not used to going to the No. 2 restaurant to grab their place.
But it's also good to eat once in a while. An Chen and Ji Wanxing walked into the door of the No. 2 restaurant and heard someone arguing in line at the first window in front of them.
An Chen took a closer look, and one of them turned out to be Jin Xiluo, a core member of the Emperor's Sky Shield and a rocket expert: "...... No, tell me why you can't do it? I've got everything ready for the model here, so why don't you just cut in the team and do our aerospace work first? ”
"Xiaojin, it's not like we won't do it for you." The other party was an older female engineer, "Your aerospace work is in a hurry, isn't our aviation in a hurry?" We also have to have a first-come, first-served basis, right, you are delayed in submitting the project, and the time cannot be scheduled, this is not a problem with our supersonic wind tunnel, right? ”
