A nation's industrial development begins with junior engineers.

Leaving aside the nominal family connection...

This is Teacher Zehui in front of me; others are people who studied under Marie Curie.

Look down at your nose, and your nose will reflect your heart; the little tuft of hair will instantly become obedient.

Hello, Teacher Zehui!

"Okay, good girl. Let's stick to the same question: how did you discover the advantages of gas centrifugation?"

Hearing this old question, perhaps still harboring resentment towards the person who had inexplicably put on airs before him, the young man said rather bluntly, "So what if you saw it? You noticed it!"

"Everyone can discover good things, unless they're like that person above, who doesn't use their brain all day long, or only uses crooked ideas!"

Teacher Zehui was taken aback. Hey, why does this sound like my tone of voice? This kid is to my liking!

"Hey, if that's really the case, then your contribution..."

Jiang Xia shook his head, his little tuft of hair swaying: "These aren't any big contributions. I just stayed in the back, picking up scraps from others. To put it bluntly, it's all copied!"

"Copy? Ha, if it were still gas diffusion, you could say I copied, but this is centrifugation. Even if I studied under that 'madam,' this centrifugation method only exists in theory, with only theoretical data for single-stage extraction. But in your report, it's..."

Hey, you're mistaken. This gas centrifugation method was first proposed in 1919 and was first successfully applied to the separation of chlorine isotopes in 1934.

Although it was not adopted in the Manhattan Project, Bald Eagle included it in its subsequent process improvement plans.

Of course, all of the above is information deciphered in later generations, so it's reasonable that Teacher Zehui didn't know it, and Jiang Xia didn't correct her.

A group of people came down from upstairs making a ruckus. Teacher Zehui immediately shut up and pulled Jiang Xia into a small office.

"Teacher Zehui, isn't that the guy in charge of filmmaking? Why is he here at the Second Ministry of Machine Building?" Jiang Xia peeked at the man as he walked down the steps with an air of superiority.

The beautiful woman leaned casually against the table, her hands in her pockets, looking very elegant.

"Oh, she said she wanted to make a movie to show the greatness of women in the new era. Isn't she just here to interview me? I don't have time to waste arguing with her."

"Learn from me? Ha, they're in for a world of trouble. I'm so out of touch with the times, hahaha!"

Teacher Zehui laughed heartily.

"Well, it seems this person got the short end of the stick in front of you, so he's taking it out on me, right?" Jiang Xia shook his head, thinking to himself.

"Alright, stop calling me teacher, just call me Senior Sister. Aren't you from Wudaokou too?"

"Okay, Senior Sister Zehui."

Jiang Xia called out "Senior Sister" in a clear and crisp voice.

You must know that the beautiful woman in front of him is someone who has crushed countless geniuses, so Jiang Xia called her "Senior Sister" with extreme respect.

Nonsense, she was the top female student in the college entrance examination in the 30s. After entering Wudaokou School, she ranked first in that grueling class of only 10 students who graduated. When she went to Germany, her doctoral degree was in experimental ballistics!

Why did you choose this major?

"I want to write this in a notebook!" These are someone else's exact words.

"A new, accurate, and simple method for measuring the velocity of bullets" has been applied countless times. For example, Jiang Zemin's father used a method developed 20 years ago to calculate missile velocity.

She was the first in the world to capture a four-split track. With the Nobel Prize within her grasp, this senior sister returned to China with her husband in style.

After returning to China, the country's first reactor and cyclotron were built under the leadership of this senior female student. In particular, the important elements used in it were specially given to her by that "madam".

Back in the 1950s, did you know how valuable this important element was? Especially since it was a high-purity element from that "lady's" laboratory.

Yes, there's a bit of anecdotal history, related to notebooks. They once tried to exchange twenty tons of gold for a few grams of this high-purity element.

But this senior sister simply handed over the gift!

Regardless of what others thought of her, Jiang Xia always believed that this senior sister possessed a chivalrous spirit of "leaving without a trace after accomplishing her task." Especially the "out-of-date practices" she just mentioned—perhaps this is what caused her quite a bit of trouble!

Why?

Because of this senior sister, she was later forced to clean toilets.

Eight years!

Jiang Xia was furious when she saw the person coming down the stairs.

If I can't solve the problem, can't I at least solve the problem with the person?

This staircase is pretty high, should we just go for a brutal charge? At worst, I'll just go eat sand with Jiang's dad!

Jiangxia lowered his head, ready to take action.

Eh eh eh?

Senior Sister, why are you pulling my hair?

"Where do you think you're going! Tell me quickly, how are all these centrifuges planned to be arranged in different levels, and how will they be interconnected?"

The senior sister pointed at Jiangxia's blueprints and began firing off a barrage of questions.

"Also, although two thermal power plants have been prepared in a certain area, the power supply is still quite tight. With so many pieces of equipment you've set up, putting aside the manufacturing issues, the power supply must be very tight, right?"

"Ha, Senior Sister, I'm wide awake now that we're talking about equipment!"

When Jiang Xia heard his senior sister mention these issues, which were all things he had already considered beforehand, he couldn't help but feel a sense of satisfaction, as if his itch had been scratched. Temporarily putting aside his inexplicable anger, he grabbed a newspaper from the table and began to write and draw on it.

"You see, the advantage of my centrifugal method is that it can be used to produce economically on a smaller scale. Later, when we have more strength, it is easy to expand the production scale!"

"Furthermore, because the separation coefficient of gas centrifugation is much higher than that of gas diffusion, fewer cascade stages are required. In particular, its power consumption per unit separation work is only 6% or even less of that of diffusion!"

"Why is the power consumption so low? Please take a look here!"

As they spoke, Jiang Xia pulled out a detailed structural diagram of the centrifuge. Wait, something seems to be missing?

Hmm! No, the blueprints are all in my head!

"Look at this. Although I don't know yet whether the technical parameters of the stepper motor from the post office can meet my requirements, with our current level of technology, there is absolutely no problem with high-strength rotor materials and high-precision parts processing!"

The eldest sister chuckled softly: "That's right, I forgot about your processing center, hmm, Cat House?"

"Hehe, that's not all. Look at this formula, if we plug in the parameters..."

Jiang Xia pushed the paper and pen aside, indicating that his senior sister should do the calculation herself.

Senior Sister Zehui didn't stand on ceremony; she took a pen and paper, sat down, and buried herself in calculations.

Jiang Xia had been talking for a long time and was extremely thirsty. He picked up the water bottle that Lao Wang had handed him from Dr. Lan Ying and started pausing again.

Ugh, it still tastes awful.

Dr. Lan Ying's situation is really tough; what kind of water is she drinking?! I should probably wash my kettle too; there's so much limescale!

Jiang Xia spat out a stone-like object and looked out the window.

Huh? That person wants to get into the car that brought him here?

Hehe, it seems the Badge Warriors won't let her go?

Oh my, that face is so dark, she could play Bao Zheng without makeup...

Hey, everyone was saying this was an old person's car. Which old person is it? I forgot to ask, but it's not a big deal...

Ah!

Oh no, I was in such a rush that I forgot to ask Lao Wang what model of telephone line the post office is using. I wonder if it's possible to use a modem directly on the telephone line?

Jiang Xia reached into his spatial storage and touched the few small items he had just redeemed from the system space.

To be honest, Jiang Xia had only heard of modems by name; he had never actually seen one. That's because the Jiang Xia of later generations used optical modems!

Furthermore, modern computers no longer have external modems, oh, there are exceptions.

A large factory in later years imported a production line from abroad. To meet specific communication needs, they customized several industrial control computers that retained modem interfaces. However, that modem was also integrated onto the motherboard…

When Jiangxia first encountered the internet, modems had already been obsolete for over a decade, so they were something that people had only heard of but never actually seen in the market.

Uh, it's a bit difficult to hold back.

However, the items redeemed with points are somewhat different from those obtained through a lottery. They not only come with physical objects, but also blueprints and even accompanying instructions.

Perhaps because the exchange was made in that adult's car, the accompanying book was "Detailed Explanation of the TCP/IP Protocol Family".

Ah, although Jiang Xia didn't delve much into these application-level protocols, he did know a little about telnet for transmitting messages and FTP for transferring files.

No, it doesn't exist. Let's get the material out first, and then great scholars will refine it!

Currently, a Chinese-language environment can be achieved on computers. With the addition of a modem, setting up a simple network between various research institutes should not be a problem.

Combined with a basic computer remote login protocol like telnet, you could create a forum for Chinese scientists.

It's much better to put the relevant project progress of each factory and research institute on the list than to have everyone burying their heads in repetitive research!

It sounds wonderful! Although this is a big step and there are many problems to solve, the future is promising!

"Come on, let's drink to the future!"

Jiang Xia, in a pretentious manner, raised the kettle and toasted the setting sun.

He took several large bites, one after another.

Ptooey, ptooey, ptooey! What's in here?! Is the limescale really that big?!

Jiang Xia looked at the large calamari in his hand. Why did it look so familiar?

"Junior Brother! Junior Brother!"

"Did I calculate that correctly?" The senior sister looked at the series of data before her, somewhat surprised. "The energy consumption for increasing the key element from 0.71% to 3% is only this much?"

"How did you arrive at this formula? This isn't Deng's initial formula, is it?" The senior sister calculated for a long time before realizing that the formula seemed a bit different!

"S?)+P?V(xp?)?F?V(xf?)?"

"I've optimized it!" Little Ahoge boasted shamelessly.

This formula is actually the formula for calculating the separation work (SWU) of a centrifuge unit.

W = Consumed mass

P = Output quality

F = Input quality

The most important part is actually the calculation method of V(x).

This is the essence of the formula. This formula, which has become so ubiquitous in later generations, was originally summarized by someone. But does it matter who invented it?

Since it is based on fundamental theories in the fields of nuclear physics and chemical engineering, using it ahead of time is not a waste of the hard work of many researchers.

“V(x) = (1 - 2x)ln(x1 - x)? You brat! Why did you write this in the project proposal?”

While scribbling on the relevant sections of the project proposal, the senior sister scolded the little idiot without a second thought.

Okay, okay, you're absolutely right!

Little Dumb Hair pouts: Isn't it just what they said about strictly reviewing projects? If it's going to be strict, then it definitely needs formulas; just talking about it won't do.

We can't let our reputation as an honest young man be tarnished!

"How long will it take you to make this centrifuge?"

"Tsk, if it weren't for that incident just now, after understanding the supporting facilities, we might have been able to build one tonight. The old master craftsmen in our factory are incredibly skilled!"

Still lost in the ambiance of enjoying a drink with the sunset, the little guy with the dazed hair casually chimed in when he heard the question.

Huh? That's not Senior Sister's voice?

Little Dumb Hair reacted extremely quickly, taking two steps to block the senior sister's path. He casually pulled a steel plate from his satchel and shouted at the newcomer:

"Hey! Secret Service, halt in your tracks!"

"Uh, uh, uh, should I call him Senior Brother or Brother-in-law?" Looking at the person who came, Little Doe was a little unsure of what to call him.

The right hand is raised high, unsure whether to lower it or keep it raised.

Seeing her thin junior brother standing in front of her, Teacher Zehui smiled broadly. This junior brother was indeed as loyal and righteous as Teacher Pei had said.

"Call him brother-in-law, not senior brother. He's not good enough for me. His grades aren't as good as mine. He doesn't deserve the title of 'senior'!"

Teacher Zehui rolled her eyes at the newcomer: "Look how scared our junior brother is! From now on, you must knock before entering, understand?"

"Tsk, Madam. If you go by this, the generational order is quite messed up..."

The man with a pen stuck in his Zhongshan suit looked at his wife with a sense of helplessness.

What can we do? They chose it themselves, so we'll just have to spoil them.

Besides, being called brother-in-law by this junior brother doesn't seem like a bad deal!

……

After another round of intense discussion, the initial task of supplying 20 centrifuges gradually took shape during the group's discussions.

"This should be the minimum quantity needed to meet the requirements. If we could get a thousand or so units, according to that formula, we could probably produce enough key elements for the initial experimental abundance in a month," the senior sister said with some regret.

"It's alright, we can wait this long. It's always better to play it safe in these kinds of situations!" Senior Sister's partner added.

"Oh no! That uncle from the machine factory is waiting for my reply! His flight was this afternoon, and I've made him miss it!"

After the plan was approved, Jiang Xia suddenly remembered the messenger uncle who was still staying at the steel rolling mill guesthouse.

"Oh, it's nothing. I let him stay at the steel rolling mill. In three days, he will be escorting the centrifuges."

The minister of the Second Ministry of Machine Building stood to the side with a smile. After seeing that person off, he listened to the discussions coming from the small office.

Upon closer listening, tsk, what are you waiting for? Badge Warrior, quickly seal off this floor!

No, not just this floor. The soundproofing in this old building is terrible. I'll just seal off the whole building. If we go back two hours, everyone in this building will have to sign a confidentiality agreement and memorize the confidentiality regulations!

As a result, the small rooms in the annex building were overcrowded.

Li Huaide was secretly moved again:

Waaaaah~~ Xiao Jiang is so kind, sending so many people to tutor me.

Xiao Jiang, I'm willing to die for you!
