Chapter 124 How to train talents

From the very beginning, Zuo Menggeng's foundation was rough.

The lack of talents has always been the biggest problem bothering him.

This is also the main reason why Zuo Menggeng limited the rear camp to [-] people.

If he really wanted to squeeze Liu Yuanqing away or turn Liu Yuanqing into a puppet, with the cooperation of Cao Wenheng, Qu Shixu, and Zhang Jimeng, it could be done.

In the name of the Linqing Association, it is not impossible to directly gather an army of tens of thousands of people.

But he knew very well that such an army was not much better than those peasants who caused chaos in northern Shaanxi.

There are not many soldiers, but the most expensive.

After cultivating these [-] people, there are [-] seeds, which can bring him a steady stream of powerful troops.

Up to now, all the weapons have been equipped to the troops, and Zuo Menggeng doesn't think the rear battalion is a powerful army.

Because this army has never confronted any enemy, it is just a swaddle tempered by fantasy.

A great army cannot be born without the baptism of blood and the tempering of sacrifices.

Where there is a lack of talents, it is not just the back camp.

The same is true for factories and villages.

Although there are more than a hundred scholars and children, the old knowledge these people possess makes them inferior to ordinary people with a blank sheet of paper when accepting new ideas.

Zuo Menggeng could only place these people in some grassroots positions, working, studying, and transforming at the same time.

Coupled with the education he was personally responsible for, he gradually accumulated useful talents.

This is the limit of his foundation's ability to maintain its current scale.

Zuo Menggeng was waiting, waiting for a good opportunity to transform the back camp.

Wang Xiuzhi's bedding factory ushered in an opportunity.

Zuo Xianmei's action immediately solved the accounting problem that had plagued the clothing factory for a long time.

The superficial accounting methods learned from Zuo Menggeng were applied by Zuo Xianmei to the financial problems of the clothing factory, but they became a magic weapon.

Originally, Wang Xiuqin and others needed to calculate the accounts for ten days and half a month, but Zuo Xianmei solved it in only one morning.

Looking at her delicate appearance, the big guys didn't think highly of her.

Farmers, even women, are useless without strength.

But the knowledge displayed by Zuo Xianmei immediately conquered the big guy.

"Oh my god, sister, without you, we would be exhausted just to settle accounts. No, I will tell Qianza later. You are so powerful, how can you always hide at home, how good you are here to help us. "

"I……"

Zuo Xianmei instinctively wanted to refuse, but for some reason, when she was busy just now, the feeling of being needed made her quite reluctant.

Wang Xiuqin is short-tempered and not polite.

Checking the time, he grabbed her hand and walked out.

"It's time for dinner, let's go to eat first. Qianzao is going to give a lecture at the school in the afternoon, and I will go there with you, just to talk to him."

On the way to the cafeteria, Zuo Xianmei was very curious.

"Does brother still give lectures?"

That elder brother, who never disdained the classics and articles, actually went to be a teacher for others, and he was not afraid of misleading his children?
"Qianzuo doesn't give lectures, where did we learn characters, mathematics, and accounting? Let me tell you, Qianzuo has strict requirements for learning. There are squadrons in the back camp because they are not active in learning. He's fired."

The mode of dining in the canteen opened Zuo Xianmei's eyes again.The scene of thousands of people eating together is something she will never forget.

Although it was just a very common food, the movement of thousands of people stirring the rice spoons together whetted her appetite, and she ate two steamed buns for the first time.

In the afternoon, the two of them turned to the school and easily found the place where Zuo Menggeng was in class.

Today is not in the classroom, but on the playground.

Four to fifty children sat in a row, all curiously looking at the long iron tube in Zuo Menggeng's hand.

And this long iron tube really made Zuo Menggeng want to cry without tears.

After nearly six months, the telescope was finally made.

It is not so troublesome to make tungsten steel milling cutters, mercury fulminate, and flat glass. Why is it so difficult for telescopes?
Because the craftsmen have no basis for grinding lenses.

Daming wanted to find craftsmen who knew how to grind crystal and glass. Even if there were, it would be difficult to invite them.

Zuo Menggeng had visited Linqing many times before, and made many inquiries, but he couldn't find a suitable craftsman.

There is no way but to find exquisite crafts from existing craftsmen and refugees, and cultivate them from scratch.

If the craftsmanship can be gradually polished and proficient, the uneducated craftsman has become the biggest difficulty in making telescopes.

Making telescope lenses is not something that can be ground into shape by hand.

This involves precise optical knowledge and very good calculation ability.

Although a piece of concave lens and a piece of convex lens are contained in the two ends of cylinder, just can realize the basic function of telescope.But such a telescope is fine for ordinary play, and it cannot be used for military use at all.

Because the observable distance is too short, there is almost no difference from visual inspection.

In order to maximize the effectiveness of the telescope, it is necessary to go through strict calculations to determine the specifications of the convex and concave lenses, the specifications of the cylinder, and the exit pupil distance.

Of course, if you want to make a top-notch telescope, you need to add prisms to it.

But with the technology of this day and age...

The craftsmen should grind the concave lens and the convex lens well.

All the calculations were basically done by Zuo Menggeng alone, and then handed over to the craftsmen for grinding.

However, because the craftsmen do not understand the data, mistakes will inevitably occur again and again during the grinding process.

Craftsmen can only correct mistakes little by little, which is naturally time-consuming and labor-intensive.

As for the discarded lenses, it is even more unknown how many there are.

At this time, Zuo Menggeng couldn't help but think of the girl who was far away in the capital.

If she is here, with her superb calculation ability and geometric knowledge, she can definitely solve many problems for herself.

Back home, she must be bored without anyone to communicate with, right?

Zuo Menggeng guessed wrong.

Xu Ruolin is not only not bored, but also very busy.

Xu Guangqi's study has been requisitioned by her.

Xu Ruolin is doing something big.

Compile "Geometry Elements".

To be precise, it is the compilation of "The Elements of Geometry" co-authored by Xu Guangqi and Matteo Ricci.

After getting in touch with more modern mathematical expression habits and methods from Zuo Menggeng, Xu Ruolin increasingly felt that Xu Guangqi's translation of "Elements of Geometry" was too obscure and difficult to read and understand.

She told Xu Guangqi her thoughts, and specially compiled a part for Xu Guangqi to read.

Xu Guangqi thought about it for a while, and found that Xu Ruolin's adaptation was more refined and easier to read and use, so he strongly supported her approach and provided his own study room.

Xu Ruolin was greatly encouraged by this, and immediately threw herself into it.

Her ambition is not only to compile the first six volumes of "Elements of Geometry", but also plans to compile the next nine volumes.

In the new compiled version, Xu Ruolin completely copied Zuo Menggeng's method.

The original right-to-left, top-to-bottom writing habit of Chinese characters is changed to a left-to-right, top-to-bottom pattern.

Calculation formulas are also expressed in a combination of letters, symbols, and graphics, which instantly refreshes the original cumbersome manuscript.

But obviously, doing this work must be a long process, and Xu Ruolin did it alone, and the progress was not fast.

At present, there are two places in Linqing that can produce glass.

One is Fuyao Group, and the other is Houying Glass Institute.

The glass produced by Houying Glass is better in quality, higher in purity, and its clarity almost surpasses that of later generations of glass.

Just because the glass here is soda ash added in the process of making it.

High-definition glass is also the basis for making telescopes.

This is a secret, even inside the back camp, only a very small number of people know it.

Now, the telescope finally has a finished product.Before using it for the army, Zuo Menggeng took it to the school.

Compared with other teachers in the school, the courses he is in charge of are not standard, and he does not limit the content of the lectures.

Zuo Menggeng is very clear that when it comes to enlightening children, he is far inferior to those scholars and children.

Even if he can adopt some methods of children's enlightenment from later generations, he has never been engaged in this industry and is a complete layman.

The only thing he can do is to open the door of imagination to the children of this era, so that their future has unlimited possibilities.

This is what he hopes most.

After all, soldiers and officials are easy to handle. A little bit of training can always get enough numbers from practice.

But mathematicians, physicists, biologists, chemists, etc. are the key to whether the Chinese nation can take a different path.

He is incapable of cultivating a child from nothing to a top scientist, because the knowledge he has mastered is weak at a certain level.

The best way is to expose children to the unknown of this world through various means when they are young.

Just like now, Zuo Menggeng placed the telescope in front of everyone.

"Today, let me let you know what optics is..."
