early morning.
We had breakfast as usual, but because there was one more person, we had one more breakfast.
But Su Jing didn't need to worry about any of this. Zhu Biao completely took over the responsibility of taking care of his younger brother Zhu Ju.
As the saying goes, an elder brother is like a father, and Zhu Biao did this very well.
Of course, Zhu Rui is not as difficult to control as a nine-year-old child in the general sense. It is not an exaggeration to describe him as a little adult.
It's just that Su Jing is still a little uncomfortable with the sudden presence of a nine-year-old child next to her.
He still remembered the conversation last night.
It can only be said that there is no shortage of talented young people in every era, no, they should be called precocious children.
As for whether he is a genius or not, that depends on the future.
"Master Su, are you teaching my brother today?"
Zhu Biao was the first to ask.
Since his younger brother has a strong desire to learn from Su Jing, and it is not just a whim, he, as an older brother, naturally has to support him.
Su Jing glanced at Zhu Biao and knew the meaning of these words, but he did not answer and continued to eat breakfast.
Zhu Rui was much calmer and ate breakfast in silence.
At this dinner table, one is his teacher and the other is his eldest brother.
They are all elders, people who need to be respected and cannot talk casually.
Seeing that Su Jing didn't speak, Zhu Biao didn't continue, and the breakfast ended in silence.
"Niu Yi, you should continue to make telescopes today."
Su Jing suddenly asked Zhu Biao.
Zhu Biao was stunned for a moment, then nodded and said, "Yes, Master Su."
There was some joy on his face, but not for himself, but for his younger brother Zhu Ju.
Su Jing asked her if she would continue to make telescopes at home. Wouldn't that mean she had time to teach Zhu Rui?
"Stop for a moment and I'll teach you how to make another thing."
Su Jing's words made Zhu Biao stunned. Why were they different from what he thought.
this.
Zhu Biao was a little at a loss for a while.
"Why, you don't want to learn?"
Su Jing's voice sounded faintly.
"No, Master Su, students are willing to learn."
Zhu Biao replied immediately.
Zhu Biao had no reason to refuse Su Jing's offer of teaching.
"Then what should my brother do now?"
Zhu Biao asked Su Jing again.
Su Jing turned her head and glanced at Zhu Rui and said, "Whatever, you can do whatever you want, I don't care."
"Thank you Master Su, the student understands."
Zhu Biao immediately thanked Su Jing, and did not forget to urge Zhu Rui on the side: "Fifth brother, why don't you thank Master Su quickly."
"Thank you Master Su."
Zhu Ji responded quickly and immediately imitated Zhu Biao and thanked Su Jing.
Both of them understood the meaning of Su Jing's words, and Zhu Rui could listen.
Although he didn't know what Su Jing would teach Zhu Biao, Zhu Biao was still quite excited.
The two of them followed Su Jing to the courtyard, stood respectfully, and waited for Su Jing's teaching.
Su Jing directly took out a dozen small spherical glass beads the size of eyeballs, placed them in front of the two of them and said: "Your task today is to polish a small bead by one person. The smaller the better, the rounder the better, the surface cannot be If there are any flaws, there should be no cracks or impurities inside. At least three of them should be found for me.”
Um?
Isn't it teaching?
Why do you suddenly need to polish the glass?
Zhu Biao and Zhu Ru looked at each other, somewhat confused about Su Jing's operation.
But the two of them obediently picked up the tools and started polishing.
Zhu Biao obeyed Su Jing's words unconditionally.
As for Zhu Rui, his elder brother did it obediently, so what right did he have not to do it?
The two of them started polishing it.
Each person has a small turntable, fix the glass in the center position, then turn the turntable, first use coarse sandpaper to sand off the edges little by little, and then change to finer sandpaper.
This is a prop specially made by Su Jing for polishing lenses, which is similar to making pottery.
Rotate to ensure consistent grinding.
Otherwise, every direction must be judged by the naked eye, and it will take years and months to polish it.
Nowadays, it is not particularly difficult to polish beads.
Moreover, the raw materials Su Jing gave were originally glass beads, but they were slightly larger.
All it takes is patience.
Coincidentally, both Zhu Biao and Zhu Ru have this point.
Starting from breakfast, the two of them continued to fuck until noon.
When Su Jing appeared again, she found that several polished glass beads were already placed on the plate, which were only the size of chopstick heads.
The two of them continued to polish it, while Su Jing picked up one, held it up and observed it carefully through the light.
The surface is quite rounded, and there are no major problems internally. It is basically guaranteed to be flawless.
After looking at all of them, Su Jing nodded slightly.
Zhu Biao and Zhu Ru did a pretty good job. Although they don't know how effective these glass beads will be, they can at least give it a try.
However, Su Jing didn't have high hopes. After all, it was just something polished by hand, and there was definitely a gap between it and something made with a machine lathe.
If that didn't work, he would have to spend money to build a wooden lathe, teach himself how to be a lathe, and give it a try little by little.
"Okay, let's stop. After dinner, we will officially start teaching in the afternoon."
Su Jing said to the two of them.
"Yes, Master Su."
"Yes, Master Su."
Zhu Biao and Zhu Xi nodded, and the three of them quickly finished their lunch.
As soon as they got home, Zhu Biao and Zhu Ru were looking forward to it.
What will Su Jing teach them?
Su Jing didn't take any lunch break to irritate the two of them, and took out the things she had prepared in the morning.
A cylinder made of cardboard, as well as bronze mirrors, silk cloth, thin pieces of wood and other random things.
Su Jing cut the thin piece of wood into a shape suitable for the cylindrical lid, poked a small hole in the middle, and then covered it with a layer of silk cloth. Following the small hole in the middle of the lid, she poked the silk cloth in the same position. break.
Then Su Jing took out a glass bead that Zhu Biao and Zhu Ru had polished and stuffed it into the small hole.
With the flexibility of the silk cloth, it was firmly stuck at the hole.
The four lenses that had been prepared long ago were stuffed into the lens barrel and placed according to certain specifications.
After being busy for a while, Su Jing stopped.
"Niu Yi, go get a fresh leaf."
Su Jing said to Zhu Biao.
"Yes, Master Su."
Zhu Biao nodded and immediately fetched a leaf. Although there were not so many fresh leaves this season, they could still be found.
Su Jing took the leaves, placed them in the middle of the cylinder, and placed them on the loading platform. Then she moved these things into the house. Zhu Biao and Zhu Ru also followed in. The door was closed, the windows were closed, and the house was instantly filled with It got dark.
"Niu Yi, go to the window, open it a little less, and use the bronze mirror to reflect the sun. Come to this position."
Su Jing gave the instruction to Zhu Biao again, and the position pointed by her finger was the small gap in Yuantong.
"Okay, Master Su."
Zhu Biao immediately followed Su Jing's request.
A beam of sunlight was reflected to the position of the cylinder.
Su Jing put her eyes on the small glass bead, then carefully moved the log piece to adjust the focus.
After some patient attempts, a clearer image finally appeared in Su Jing's field of vision.
"Fortunately, it works."
Su Jing muttered to herself and relaxed a little.
This condition can only be described as crude.
Although what I saw was not very clear and the multiple was not that big, it was still okay.
At least in front of this new student Zhu Ju, he should be able to show off.
I can’t grow it, but I can do it in other places!
At this moment, Su Jing could see the veins and lines of the leaves in her field of vision, and some extremely subtle details could be seen clearly.
That's right, this is Su Jing's homemade microscope.
This was what a child taught Su Jing when he was playing with the children during a visit to the orphanage in his previous life.
But the props are much more advanced than this.
I bought glass beads, small plastic bottles for the cylinder, a small flashlight for lighting, and the stage also has the magic tool of scotch tape.
It can only be said that Su Jing felt that such a simple homemade microscope was really crude at the time, but now he only feels that the one at that time was actually very advanced.
Although the materials are things that can be seen everywhere in life, in the Ming Dynasty, it was really difficult to find substitutes.
Whether it is glass beads, plastic medicine bottles, or flashlights, they are all things that can only be made by modern industry.
These themselves represent the level of development of science and technology and the level of industrial development.
Su Jing now has a better understanding of the three major industries and productivity.
Of course, Su Jing is still quite proud now.
Because a man from the Ming Dynasty who couldn't even get the materials from the orphanage actually DIYed a microscope!
Although the microscope does not seem to live up to its name, it is at least usable.
"Niu Yi, don't move."
Su Jing gave instructions to Zhu Biao, then looked at Zhu Ru and said: "Niu Su, come here and take a look, just put your eyes on it."
"Yes, Master Su."
Zhu Rui immediately came to the homemade microscope, imitating Su Jing's example, and put his eyes on it.
Just one glance and he was attracted.
"This is"
Zhu Ju looked at the scene in front of him and was speechless.
He usually carefully observes the shape of the leaves, including the texture on their surface and various details.
So at this glance, he saw what was in front of him.
Of course, it was also due to the average magnification of Su Jing's homemade microscope that it couldn't magnify too much.
At the same time, the pattern is somewhat distorted and offset due to the use of polished glass beads.
But this still made Zhu Ru feel extremely shocked!
His elder brother Zhu Biao had already introduced the telescope to him last night, an artifact that could see miles away.
He was extremely surprised and shocked at that time.
Now, another small artifact appeared in front of me.
Zhu Xi's heart could no longer be described in words.
"Be careful, it won't be easy for me to debug."
Su Jing reminded, then came to the window and said to Zhu Biao: "Give me the mirror, you can go and take a look too."
"Yes, Master Su."
Zhu Biao nodded, carefully handed the mirror to Su Jing, and then slowly came to the microscope.
Zhu Xi stepped back, both of them being very careful.
Zhu Biao lowered his head and raised his eyes. The sight in front of him also shocked him.
"What's this?"
Zhu Biao couldn't help but ask.
In terms of plant morphology or leaf morphology, Zhu Biao really didn't know as much as his younger brother Zhu Ju.
"Brother, what you see is the leaf you picked just now."
Zhu Zhu replied from the side.
His words were a little excited, but because Su Jing and Zhu Biao were beside him, he restrained himself.
"Leaves? Did I pick them?"
Zhu Biao was startled, a little unbelievable, and looked at it carefully several times.
Only then was it confirmed that it was indeed a leaf.
"Master Su, students bow to you!"
Zhu Biao raised his head and said respectfully to Su Jing.
Zhu Xi also followed suit and said: "Students bow to you."
"Okay, let's do this for now. You can open the doors and windows."
Su Jing felt tired holding the mirror, and it was very dark.
The effect he wanted has been achieved.
The shock in Zhu Biao's and Zhu Xi's big eyes greatly benefited Su Jing.
Su Jing felt that she was well-deserved for such a shock.
After all, it’s possible to build a microscope under such crude conditions. Isn’t that awesome?
Zhu Biao and Zhu Xi were a little unfinished, but they still followed Su Jing's instructions and opened the door.
The sun shone again, and Su Jing walked up to the two of them.
Zhu Biao and Zhu Ji looked at Su Jing, feeling that Su Jing seemed to be shining brightly and dazzlingly.
"Master Su, what is the name of this thing?"
Zhu Biao asked Su Jing.
Su Jing smiled and said: "This thing is called a microscope. It is specially used to observe tiny things, so it is called a microscope."
microscope!
"Micromicroscope, what an apt name."
Zhu Biao read it and said sincerely.
Zhu Rui looked at the simple microscope as if he were looking at a treasure.
Su Jing saw Zhu Ru's love. For a child who loved botany, it was not natural for him to like microscopes.
"Niu Su, how about this microscope?"
Su Jing asked Zhu Rui.
Zhu Xi said extremely seriously: "This is a divine object!"
"good."
Su Jing smiled and said: "Then I'll give it to you."
Note: The author of this self-made telescope has personally made it for his niece, and it is indeed possible. The details in the book are not complete and are slightly exaggerated, but not much. Those who are interested can search and verify by themselves.
