Zhou Mo knew his uncle's worries. When he saw the telescope image was upside down, he couldn't understand the principle and would definitely suspect that what he saw was not the real moon.

So he asked his uncle to turn the camera and take a look at the candlestick not far away.

Zhou Qun took a look and saw that the candlestick was also in an upside-down state, which was very strange. But the distance was close enough, and it was obvious that the candlestick was the original candlestick, not another one. This day, the cylinder only turned the distant object upside down, and

Enlarged.

Zhou Mo lied to him and said: "My uncle sent someone to urge my nephew. My nephew knew that his uncle was angry and he was anxious. The production was too hasty and one of the jade pieces was not polished well, so it looked backwards. But it's harmless. Observation

In celestial phenomena, there is not much difference between positive and negative."

There is no way to say that. He can't tell him that the simple Kepler refraction system is like this. It forms an inverted real image. If you want to form an upright image, you usually need to add a forward mirror, but with the current production process, it is too troublesome.

, it is completely unnecessary for observing astronomical phenomena.

Zhou Qun felt at ease and no longer had any doubts.

He turned the camera again and observed the Taibai, Zhen, Sui, Dou, Niu, Chen, Bi, Yi, Zhen and other stars one after another. The result was both exciting and slightly disappointing.

What's exciting is that Taibai Star, Sui Star and Zhenxing can all be felt slightly enlarged. After careful identification, some shapes can be vaguely seen. The different colors of the stars are also more vivid and clear than when observed with the naked eye.

.

Disappointingly, most of the other stars look no different to the naked eye. They are just bright spots.

There is nothing we can do about it. The former are all near-Earth planets in the solar system. They are relatively close and can barely be seen. The latter are stars and are too far away to be reached by this simple equipment.<

After looking around at Ziwei, Taiwei, and the Three Walls of Tianshi, Zhou Qun thought for a moment, then pointed the celestial cylinder at the moon again, and said to Zhou Mo: "Help uncle get paper and pen, and ask for wolf cents."

Zhou Mo did as he was told, brought paper and pen to his uncle, and polished the ink.

I saw Zhou Qun spread out a piece of yellow paper on the case, put it on the paperweight, and picked up the wolf hair, looking focused and rigorous.

He glanced at the sky cylinder for a while, and wrote and drew on the yellow paper for a while. From time to time, he also adjusted the direction of the sky cylinder, because the moon was moving and would go out of sight every once in a while.

After a long time, a simple half-moon picture was drawn on the paper.

It is worth mentioning that Zhou Qun drew the spherical structure of the moon, and the invisible shadow parts were blackened with a pen. Several obvious craters were marked, and their relative positions were relatively accurate.

In 223 AD, in Langzhong, Yizhou, humans used telescopes to observe the moon for the first time and drew a moon phase diagram with the accurate relative positions of craters.

In the West, it was not until 1,400 years later that the Italian Galileo completed this feat.

This is a small step for Zhou Qun, but a giant leap for mankind.

It wasn't until the sky turned white in the east, and all the stars were hidden in the white mist of morning glow, that Zhou Qun put down the celestial machine in his hand, still unsatisfied.

He is already old and cannot afford to stay up late like this. At this moment, his eyes are bloodshot and sore. But he does not feel tired at all. Instead, he is still very excited and cannot calm down for a long time.

He felt that this night's observations were more fruitful than those in the past ten years. The mysterious door of heaven seemed to slowly open a crack to him, allowing him to have a glimpse of its secrets.

"Tianji Tube, what a good name." Zhou Qun sighed.

Zhou Qun was still not satisfied. When he saw the sun rising slowly from the east, he suddenly had a whim and wanted to use this sky camera to watch the sunrise.

Zhou Mo was yawning when he suddenly saw his uncle move the stand and point the camera at the sun. He was startled and quickly jumped up to stop him.

I couldn't help but lie again. I said that during the test yesterday, I found a dog and looked at the sun. The dog was blinded by the light. It was very scary. My uncle must not do this.

……

After that night, Zhou Qun never mentioned anything about marrying a barbarian woman or the Mianzhu Qin family to Zhou Mo.

With this heavenly secret tube in hand, everything will be as if nothing happened.

Zhou Mo, on the other hand, lost no time in launching a new round of deception on his uncle.

"Uncle, after my nephew's research, the barrel can actually be improved. After improvement, the field of view will be wider, and at the same time, you can see farther and clearer."

Zhou Qun was overjoyed: "That's great! My dear nephew, without further ado, go and help my uncle handle this matter immediately."

"Hmm..." Zhou Mo shook his head and frowned, "It's not easy to handle. If you want to improve the Tianji cylinder, you need to replace the water jade with highly transparent colored glaze. First of all, you need to improve the glaze technology. Among them,

The financial and material resources that need to be expended are probably quite huge."

Zhou Qun was a little nervous when he heard the words "not easy to handle" at first, but when he finally heard that all he had to do was spend money, he instantly felt relieved and raised his head and said, "With the financial and material resources of the Langzhong Zhou family, are they enough?"

Huh?"

"Just a word from my uncle will be enough. But I'm afraid it will take a long time. My nephew estimates that even if everything goes well, it will take at least a year and a half."

"Although my uncle is old, he is still in good health, so he can still afford to wait. I will leave this matter to you. You can decide how much it will cost. You don't have to ask me. You are busy with official duties and are not usually here.

When you are in Langzhong, you can ask your brother to take care of things for you."

The brother Zhou Qun refers to is his son Zhou Ju, Zhou Mo’s cousin.

Therefore, Zhou Mo bought all the ceramic workshops in Langzhong County in one fell swoop, gathered the skilled craftsmen among them, worked together, dug sand and gravel, and collected alkaline soil, regardless of the cost, to fully promote the glaze technology improvement plan.

As for how to make glass transparent, Zhou Mo, a history college student, knows no better than experienced craftsmen.

But fortunately, he can provide some more scientific methods, such as controlling variables as relatively accurately as possible to conduct experiments to achieve the expected results.

For example, if you want a finished product with high transparency, high-quality, high-purity raw materials are very important, and you must spend a lot of effort on raw materials.

Every experiment must be recorded in detail and filed in files. All written records must follow a unified format for comparison and improvement.

Zhou Mo told his cousin Zhou Ju all about his plan and the production concept that he knew little about. After hearing this, Zhou Ju also became very interested in the matter. He patted his chest and promised Zhou Mo that he would go all out.<

/p>

The two agreed that after Zhou Mo left, if there was any progress or problems encountered during the experiment, they would communicate as soon as possible through letters.
