Chapter 210: The Crane Mile Eye

Telescopes have an extremely important position in modern society. Military, astronomy, scientific research, and no place can be separated from telescopes. Although they are called differently, their principles are similar.

It can be said that without telescopes, the comfort of life in modern society would not be so high, and technology would not be so developed. With the good helper of telescopes, the microscope that could not be discovered by the naked eye can be clearly displayed in front of us, and humans will benefit a lot.

As we all know, ancient Chinese astronomy is very good, but it has fallen behind in modern times. What is the reason? One of the most important reasons is that there are no suitable tools. Western society is using telescopes for astronomical research, but China does not have such easy-to-use instruments. Being backward is inevitable.

In order to master the astronomical calendar, ancient China spared no effort to establish a special agency "Imperial Heaven Supervision" to observe the astronomical phenomena and write the calendar.

The invention of the telescope was done by accident, just like most technological discoveries. In the early 17th century, in order to check the quality of the grinded lens, the owner of an eyeglass shop in a Dutch town lined a convex lens and a concave lens in a straight line. Looking through the lens, he was surprised to find that the spire of the church in the distance became larger and closer, and the secret of the telescope was revealed to the world.

Of course, the owner of this glasses shop is very smart. He applied for a patent. Although he was protected by a patent, it still could not prevent the development of the telescope, because the great scientist Galileo also joined the ranks of telescope production, and the telescope developed is far beyond the size of the owner of the glasses shop.

Galileo used telescopes to conduct astronomical research and achieved fruitful results.

There are many famous telescopes in history, such as the Hubble Telescope, which are almost household names.

Different uses, the method of making telescopes is different. Of course, Chen Wanrong will not be too ambitious and pursue the kind of telescope that is out of reach. He just wants to make a telescope that is almost the same as in our modern life. Even if the quality is not as good as that of modern telescopes, it is much better than using flags and using the naked eye to observe the battle situation.

After all, telescopes are a problem of lens application. Can it be stumped by military equipment monitoring if they want to make lenses? Chen Wanrong said the request, Ye Tianheng and the others laughed and pointed at Chen Wanrong and said, "My friend, you are really scary. This thing is too simple, and this mold is easy to make."

If you want to say that lenses are indeed simple, it is hard to defend people. However, with lenses and telescopes, this has a great impact. Chen Wanrong said seriously: "Master Ye, just talking about clairvoyance is indeed simple and easy to do. Our military weapon supervisor will definitely be able to do it. But do you know what the impact will be?"

"Isn't this... you can see more and more clearly? You can see things ten miles away." Kou Yibing didn't know that the telescope function that Chen Wanrong mentioned was just a drop of water in the sea, and he didn't care at all.

Chen Wanrong thought to take advantage of the opportunity they were interested in to explain the use of the telescope clearly so that they could have a clearer understanding. After a brief thought, he said: "Master Kou, you are right, but not completely. The use of clairvoyance is far more than this. I think, if we create clairvoyance and give one to the generals, do you think they will be so laborious to command the war? The situation of the war is just a glance..."

The following words were interrupted by Ye Tianheng: "My friend, this is very reasonable. You can see ten miles away, and you can see a small-scale battle at a glance. However, if a big battle is not enough."

The battlefield varies according to the terrain and target. Even if the same number of troops starts fighting, it may not be a battlefield of the same size. In the Changping War, the entire battlefield stretched for hundreds of miles, and the entire Shangdang area was a battlefield. That's because it is mountainous and has a complex terrain. The Qin army is equivalent to the Zhao army, so Bai Qi can only use the complex terrain to siege the Zhao army.

In the battle of Tubo, after the Tang army crossed the Nujiang River, they did not advance further. One reason was that the main force of Jide Zuzan was right in front of him and he had to be defeated before he could advance. Another reason was that there was a plain area of ​​dozens of miles on the south bank of the Nujiang River, which was suitable for large armies to fight and was a good battlefield. Therefore, the Tang army stopped here and did not advance again.

Kou Yibing smiled and said, "It's enough to be able to see ten miles."

Chen Wanrong continued: "In addition to being used in military affairs, telescopes are also very useful for our military weapon monitoring. Master Ye, do you know what the world you live in is like?"

"This..." Ye Tianheng stopped asking, and was stunned for a while before saying, "What's there to ask about this? There is food and drink, the wind and the sun."

Chen Wanrong shook his head and said, "Master Ye, the world you live in is a world of dust. If you have a microscope with enough magnitude, you can clearly see how terrible the environment you are in. Countless dust wraps you. Microscope is another way to use the sight glass."

Some people were so frustrated because they saw the environment they were in clearly that they were in. When I was in elementary school, a few classmates were like this, so worried that they couldn't even eat.

"No way? Dust? Why can't we see it?" This is true, but Ye Tianheng and the others still don't believe it.

"That's because our eyes cannot see it, and we can see it with a telescope." Chen Wanrong said very affirmatively: "Even the water we drink contains countless bugs. Why is it easy to make people sick by drinking raw water? It's all right to drink boiled water? This is the reason."

"There are insects in the water?" Princess Jinxian was so shocked that her eyes widened.

"Don't listen to his nonsense! It's so disgusting!" Princess Yuzhen's white plain hands couldn't help but cover her mouth.

Anyone who has seen water with a microscope knows that there are many things in the water. Can this be fake?

Chen Wanrong smiled and said, "What we cannot see in our eyes does not exist. I will tell you a small thing in life. If there is only one beam or a few sunlight shining in in a dark room, as long as you pay attention to it, there will be a lot of dust in the space exposed to the sunlight, which is very clear."

Everyone stayed in the dark room and saw the sun shining in. They didn't care at that time. After Chen Wanrong mentioned this, everyone opened their eyes in surprise and said in surprise: "Yes! That's true!"

Princess Yuzhen frowned and felt a little worried: "According to what you said, it would be meaningless for people to live in this world."

Chen Wanrong smiled and said, "Who said it's boring? Although there are many things we unexpected in the world we live in, we are still living well? What's the reason? Because these things can't do anything to us! Princess, don't worry."

Not only Princess Yuzhen was worried, but many students were also surprised. After hearing this, they couldn't help but breathe a sigh of relief.

Strengthening their confidence, Chen Wanrong then said: "The telescope is just a tool for us to observe, which requires glass. With glass, you can make more tools to observe the stars and moon in the sky, and you will find surprising discoveries. Of course, we can't do it now, just make a telescope."

"Can you really observe the stars and moons in the sky? What would that look like?" Princess Jinxian yearned for it very much.

The stars and the moon are very beautiful things. If you can see them more carefully, it is very attractive. There are many people who have this idea, especially the students, who are fascinated by them.

"That's certain!" Chen Wanrong affirmed.

Ye Tianheng rubbed his hands and said, "My friend, since it is of such great use, we must do it no matter what. Let's be a model." He took the lead in working hard with a crutch.

Everyone applauded and followed him.

To make a telescope, the glass must be smooth and the model requirements are relatively high. Only masters like Ye Tianheng and others can do it themselves. Because the students are not so skilled, they can only help.

Even so, after the glass melted and clarified, it still made many examples, about 200.

The glass liquid was heated for a long time, and when it started to cool down, the model was already available. But there was one thing that everyone was too focused and didn't eat lunch, and no one called it hungry.

Looking at the clear glass liquid, Kou Yibing slapped his forehead and said in surprise: "How did it become like this? It's as clear as water! Does the stone have such a wonderful use?"

Chen Wanrong talked about the use of glass incredible ways. They became very interested and forgot to observe the changes in the glass liquid. If it weren't for Chen Wanrong's busy command and with their concentration, this trial production would have been scrapped.

When the cooling was done, the glass liquid became much more sticky. Chen Wanrong ordered and began to blow. Several strong men started to act in a hurry. Ye Tianheng and his friends were curious and were not as strong as those of strong men. There was no problem in taking action. As soon as the water was drained, air came out of the nozzle and it was blown into shape soon.

I originally wanted to make some glass instruments used in chemical engineering today, but I didn't expect that, and the telescope was also looking at me. Chen Wanrong planned to make fewer instruments and more lenses. I guess the instruments were almost done, so I stopped.

It is not enough to make all the remaining glass liquid into lenses.

Glass instruments are of course important, but for Chen Wanrong at present, it is far from an urgent task. First, this instrument is made for Kou Yibing to practice it so that he can find an accurate measurement method. Second, there is no corresponding reagent, and even if it is made, it will not be used. Third, there is no corresponding analyst, Chen Wanrong can use it, but he has many things and can only teach others.

In comparison, if you will fight the Post-Turks next year, this telescope will be even more important. It is precisely because of this that Chen Wanrong only made the instruments enough for Kou Yibing to practice.

Looking at dozens of empty molds, Cao Zhixiong said anxiously: "We will do it again, we will do it all."

Ye Tianheng disagreed and waved his hand and said, "Do you do so much first, let's practice your hands before talking about it. This model is not very good to do it in a hurry. Next time you do it, you have to re-engineer the model."

Making a lens is a temporary idea. Everything is too hasty, so it is not appropriate to do too much. Kou Yibing also agreed. Chen Wanrong said: "Master Ye is right. Just do some of it first, just practice it. Although you are a master and you are a clever mind, it is still necessary to practice it."

This was agreed by everyone, but everyone felt a little regretful. It would be great if they could do more.

After a rumbling stomach, Chen Wanrong remembered whether he had lunch or not, and smiled and said, "Are you guys?"

It would be fine if I didn't mention it. As soon as I reminded everyone, they found that they couldn't hold back their hunger and laughed loudly. They went to have lunch in groups. After lunch in a hurry, they rushed to wait. Some anxious students even took the meal and did not leave at all.

It was not until the instrument was cooled down, and the first thing I took out was a beaker. It was transparent, crystal clear, shining in the sunlight, and it looked very beautiful.

"Ah! So beautiful!" Princess Jinxian and Princess Yuzhen screamed first.

Before their voices were settled, a sound of surprise came from hundreds of people, with a spectacular momentum.

Such beautiful things were made of the most inconspicuous stones. It was so magical. It was unreasonable to be surprised. They all looked surprised, their eyes shining, and they stared at the beaker in Chen Wanrong's hand.

Chen Wanrong looked at the beaker for a while, and it was similar to the beaker used in modern times, but there were some bubbles and some roughness, and there was still a gap in technology. However, it was quite good to be able to do this for the first time, and Chen Wanrong was very satisfied.

Ye Tianheng stretched out his hand and grabbed the beaker from Chen Wanrong's hand. His eyes were wide open. He glanced for a while and stroked his beard and exclaimed: "What a good thing! What a good thing! If Ye hadn't seen him personally, he wouldn't believe that this was made of stones."

This sentence immediately received a lot of echoes!

Everyone became more excited and were busy taking out the instruments and looking at the shiny instruments. Suddenly, the sounds of surprise came one after another.

The last one was taken out was the lens. Chen Wanrong observed it carefully for a while and found that the workmanship of this lens was a bit poor, mainly because the mirror surface was not smooth enough and the thickness was uneven. However, it was not easy to achieve this for the first time. Chen Wanrong believed that he would do it better next time.

Put a convex lens and a concave lens in front of you, line it up in a straight line, and when you look out, the scenery in the distance suddenly becomes clearer and closer.

This is how the owner of the glasses shop in a Dutch town discovered the secret of the telescope. Chen Wanrong used the same method and it worked. Chen Wanrong couldn't help but feel more confident: "You can definitely make a telescope!"

His hands kept moving, sweeping through the crowd, each of them was visible, much more clearly than using his eyes. When he looked down one by one, he saw Gao Jian happy, excited, and a little anxious. Zheng Wanru's face was red, and he pointed and pointed around Gao Jian, unable to stop talking. If he looked down, he was the Golden Immortal Princess, his little mouth, his nose, crescent moon eyebrows, and his mirror-like skin, which could all be seen clearly.

Chen Wanrong just took a look casually. Just as she was about to move away, Princess Jinxian smiled at him, her charming expression was full of charm, and her cherry red mouth seemed to kiss her eyes. Chen Wanrong had never seen her so charming since she met her, and her heart jumped and she quickly moved away.

Next to Princess Jinxian was Princess Yuzhen. She found that Chen Wanrong was looking at her. Her eyebrows were raised, her eyes glared, and she looked angry. Finally, she even spoke up at Chen Wanrong.

If you observe with your naked eyes, you will definitely find it cute. But in this case, Xiao Xiangshe is no longer Xiao Xiangshe. The fluid on the tongue is shiny, as if a crazy rabies are licking people. Chen Wanrong was shocked and hurriedly put away the lens.

At this moment, a sound of surprise sounded. Chen Wanrong glanced at him and saw Ye Tianheng and his friends holding two lenses in their hands, observing like Chen Wanrong. They all looked surprised, and there was a little panic in their surprise.

After a while of old age, Ye Tianheng stammered: "What's going on?"

Using this method to observe, the scenery in the distance is closer and bigger, and you can see it more clearly. More importantly, it is very abrupt and scary. Anyone who imitates Chen Wanrong's actions is not mentally prepared and would not be fooled by a daze?

Seeing everyone's surprised look, Princess Yuzhen couldn't help it. She picked up two lenses and observed them like Chen Wanrong. She looked at the distance and quickly took the lens away. She looked surprised with her face, her mouth wide open, blinked her eyes and looked at the distance, and fell into confusion again.

Without thinking, she knew that she was not mentally prepared and must have been frightened by the sudden scene.

Surprise only existed for a very short time. Princess Yuzhen put the lens in front of her and observed it. This time, she was not surprised. She became more and more excited as she looked at it. She shouted at Princess Jinxian in surprise: "Sister, look quickly, it's so clear!"

Princess Jinxian was curious, but there was no lens. Although there were many lenses, in front of hundreds of people, there were still many monks and few porridges, and it was not enough. Her eyes were on the lens in Chen Wanrong's hand. Chen Wanrong knew what she was thinking and handed it to her: "Princess, please look!"

Princess Jinxian took it and imitated it and observed it. With Princess Yuzhen's past lessons, she was not surprised, but at first glance, her brows were raised a few times.

Now, this is not a workshop, but a downtown city.

Although Chen Wanrong had just mentioned this kind of thing, compared to witnessing it with his own eyes, the feeling was completely different. He gathered in groups of people, looked at me, and said the thoughts after watching it, and the words of comments and sighs were endless, buzzing.

There are many scholars of literary and literary style among the students. When they are happy, they can't help but recite a few poems. However, their poems are not very good, and the poems they recite are not very good. Chen Wanrong thought to himself, "If Zhang said this here, maybe there would be a work that has passed down from generation to generation!"

It was not until I saw it that I had enough and took about half an hour to everyone be satisfied and put the lens back.

Lens are so popular that they fall to the ground. Whenever such a thing happens, they will inevitably bring a lot of criticism. Lens are so amazing that they should be cherished.

Ye Tianheng touched his beard, Kou Yibing stroked his cheek, Liu Huaide couldn't help but rub his eyes, and everyone surrounded him with surprise on his face and asked, "General Chen, what's the reason? Just two transparent things are completely different when they put them on, and they can see clearly if they can't see clearly."

Chen Wanrong did not answer their questions, but joked: "Master Ye, you don't have to worry about not being able to see clearly in the future when you make steel. You just need to bring a pair of telescopes and look at the stove, and you will be clear!"

"Is that necessary?" Ye Tianheng couldn't help but shook his hand and smiled.

"We have to make more of this thing in the military weapon supervisors and can't just spend it on the generals." Liu Huaide was in a good mood and told a joke.

Chen Wanrong slapped Princess Yuzhen and said, "Aren't you afraid of someone suing us for the emperor?"

Princess Yuzhen looked unhappy: "Who are you talking about? Are they that bad? But if you make me a pair, I won't say bad things about you!"

Blatant blackmail!

But Chen Wanrong and the others laughed. After laughing, Chen Wanrong said, "Find a place to sit down, I will tell you this principle, and you can do it!"
Chapter completed!
