Chapter 211: A monk's line

This principle is explained clearly, which is beneficial to their understanding, so that they can make better telescopes. This is very necessary. Chen Wanrong briefly sorted out his thoughts: "This requires two lenses. One in the front is called an objective lens, which gathers the scenery in the distance into light. However, if there is only an objective lens, you can only see an inverted virtual image."

"Inverted? Didn't we see upright?" Everyone almost jumped up in surprise.

"You try it with this piece." Chen Wanrong shook the convex lens and reminded them.

The person with a convex lens in his hand immediately started to test it and exclaimed in unison: "General Chen, why are you young? You are really upside down? No, you are standing upside down, why are you upside down again?"

They were facing Chen Wanrong. Who else could they get if they didn't use Chen Wanrong for experimenting?

Looking at their shocked appearance, Chen Wanrong smiled and said, "Try putting another lens on a line."

Everyone did as they did, and a surprise sounded again: "Really! General Chen is standing again!"

The students shouted the most vigorously, as if they had seen the most magical thing in the world.

The crutch in Ye Tianheng's hand focused on the ground and said, "My friend, I understand! I really understand!"

He suddenly realized his mind, and Chen Wanrong thought about him and said with a smile: "I wish to hear Master Ye's great views."

"You can't say that you have a high opinion, you can't say that you have a high opinion!" Ye Tianheng stood up with a smile and said, "It's very simple to put it bluntly. The difficulty lies in the fact that we don't have such tools. Now, we have lenses, so it's easy to deal with. How many of you have read "Mozi"? Mozi tried small hole imaging back then. Mozi used small holes, but today we use lenses, so the principle should be similar."

Mozi conducted a small hole imaging experiment with his students, which was the first time in human history. "Mozi" records many scientific experiments, which can be regarded as a peak in the history of ancient Chinese science and technology. Unfortunately, due to many reasons, he has been stagnant in physics since then.

Small hole imaging is similar to using a lens imaging, but the methods are different. With this reminder, Kou Yibing, Liu Huaide and others who are familiar with "Mozi" suddenly realized and nodded in unison to say yes.

The students didn't have long been in the military weapon supervision. They studied the way of saints and read the books of sages in the Imperial College. They were not familiar with "Mozi" and were stunned and confused.

Chen Wanrong had just started, and Ye Tianheng thought of his agile reaction. Chen Wanrong had to exclaim: "What Master Ye said is very similar. The difference is that we are just using lenses now."

After being recognized, Ye Tianheng became even more certain: "Mozi's small hole image is an inverted virtual image, so there is no way to make the inverted virtual image stand upright. With this, it can be realized and the inverted virtual image can be turned into an upright one, making it clear at a glance, and no need to think about the whole story!"

Chen Wanrong praised: "Master Ye said very well, this is the reason for the telescope!"

Ye Tianheng understood another scientific principle. He was very excited. His throat was a little dry and he said awkwardly: "My friend, what are the requirements for this telescope? You have to tell it thoroughly before we can do it!"

Before Chen Wanrong could speak, Zheng Wanru stood up suddenly and said, "I understand. Han Fei once recorded a story where a man hired a painter to paint for him. Three years later, the painter told the man that the painting had been made. The man went to see that there was only a large wooden board, and there was nothing but paint on the board. The man got angry and said that the painter lied to him. The painter said, do you want to see a living and moving painting? Painting has always been dead and not angry, and this man didn't believe it at all. The painter said with certainty that if you build a house, the house should have a tall wall and a large window should be opened on the wall. Put the wooden board on the window, and as soon as the sun comes out, you can see a painting, a moving painting.

"This man was half-believing and half-doubted, and he really built a room and had a wall. When the sun came out, pavilions and towers, and carriages and horses appeared on the walls, which looked like a colorful landscape painting. What is even more amazing is that the characters in the painting will move. The only regrettable thing is that they are upside down."

Han Fei is a master of the Legalists. Although his books are written for the Legalists, there are many popular allusions in his books that are widely circulated. Although the students of the Imperial College are practicing the ways of saints and reading the books of saints, there are also many people who read "Han Fei" to make fun of them. When they heard this, they exclaimed in unison, "Oh, why didn't I expect it?"

With Chen Wanrong's theoretical guidance, Ye Tianheng and Zheng Wanru told the story one by one. The atmosphere was very different and suddenly became active. Even Princess Jinxian and Princess Yuzhen were all flirting with eyebrows, which was very surprised.

Chen Wanrong originally wanted to give them some more advice, but now he doesn't need it at all. He smiled and said, "What I want to say, you all said it. There is only one trick, that is, the objective lens in front should be larger. The back piece is called eyepiece, which is for people to see, and it will be a little smaller. Another point is that the eyepiece must be placed in the inverted image."

The principle of a telescope is very simple. After passing through the objective lens, you will get a reduced image. As long as the scene falls at the focus of the eyepiece, it is like looking at something with a magnifying glass, it is an enlarged scene.

The wisdom of the ancients was really unspeakable. Chen Wanrong thought it would take a lot of time, but he cracked this principle with just one word and one word. Our ancestors were really amazing! Chen Wanrong praised in his heart.

"Let's go! Go and be a clairvoy!" Ye Tianheng's crutch twitched on the ground, and his face was so excited that he was red.

Everyone applauded and followed.

Ye Tianheng pulled Chen Wanrong's arm and said, "My friend, I have an idea. This thing is good, but it takes two eyes to see it. It's too tiring to see it with one eye like us. Now that we have a machine tool, it's much easier to do."

Isn't this a telescope?

What Chen Wanrong thought in his heart was that it would be great if he could make a single-tube clairvoy, but he wanted to make a telescope, which was very surprised. However, this is a good thing and there is no reason to refuse. Looking at one eye or two eyes, there is no need to say who is better or worse.

"Master Ye, that's great!" Chen Wanrong agreed very readily.

Ye Tianheng stopped, and the crutches in his hand slashed on the ground, and actually drew the prototype of a telescope for him. The reason for this is that it is a big gap compared to the design of modern telescopes. It is not beautiful, but also a bit bulky, and it is time-consuming and labor-intensive to do it.

However, it was very rare for him to think of so much in such a short time. Chen Wanrong praised him, squatted down and corrected Ye Tianheng, which made Ye Tianheng happy. Then he smiled and went to make a telescope.

He rushed to the machine tool workshop in a burgeon. Ye Tianheng slapped Chen Wanrong on his shoulder and said, "My friend, I have been using it once, I will assign this time."

Chen Wanrong didn't agree with it, and said: "Master Ye just told me."

Ye Tianheng was quite pleased when he patted Chen Wanrong's shoulder: "There are some iron sheets here that can be used in handy. I don't use much iron sheets, but I just need to use some from time to time. If there is no such thing here, I will come in handy today. Lao Kou, Lao Liu, Lao Cao, and me, the four of us will do it. Don't do anything else, there is not much iron sheet, and it will be troublesome if it breaks it."

Kou Yibing, Liu Huaide, Cao Zhixiong and Ye Tianheng are the most exquisite military weapon monitoring skills. They have not had much time to work together, and Chen Wanrong was both surprised and expectant.

"No problem!" Kou Yibing responded readily, took off his coat, and shook his arms a few times, as if he was on the battlefield.

The servant took out the iron sheet and Ye Tianheng explained it to the three of them. Liu Huaide and the others picked up the iron sheet without saying a word and started processing it. The iron sheet of the Tang Dynasty was naturally very different from the iron sheet used in modern times. As long as it was slightly processed, it could still be used.

Ye Tianheng put the crutch and started cutting the iron sheet without measuring any size. He quickly moved a pair of large scissors in his hand. When he stopped, he cut the iron sheets one by one.

After polishing, trimming and riveting, it takes a lot of time.

Chen Wanrong and the others surrounded the four of them, and they could only watch them with their eyes wide open. The four of them were very skillful in their movements. Just one look at them to confirm that they were very accomplished craftsmen.

It was not until it was almost dark that it was completed. When Ye Tianheng and his team were dealing with the iron sheet, Zhang Deming and his team had already polished the lens. Chen Wanrong had checked it for a while, and it was not bad. The edges and corners were treated very smoothly, and there was no damage to the mirror. It should be useful.

Once you install the lens, you will be a telescope. Although it is very rough, it is done after all.

Ye Tianheng took a look and shouted: "It's done! Hey, why can't I see clearly in my hand?"

He handed the telescope to Chen Wanrong. Chen Wanrong took it and saw it. It was indeed a bit blurry. It would be better to hold it in his hand to see it clearly. He smiled and said, "Master Ye, this is because there are several problems that have not been dealt with. First, there is no device to adjust the distance, and then I will use some threads for rotation in the future. Second, there is no prism, and third, we have done it for the first time, and we will do it better in the future."

"That's it, that's it!" Ye Tianheng couldn't help but nodded, but his face was filled with regret.

This is the first telescope. It is OK to achieve this level, and you can't ask for too much. Everyone is holding the telescope, you look at it, and he looks at it until everyone has seen it, and it is already dark.

Finally, the telescope fell into Princess Yuzhen's hands. Chen Wanrong wanted to get it back, but Princess Yuzhen refused to give it to Zheng Qing. Chen Wanrong wanted to take it back and give it to Zheng Qing, but then agreed to the marriage. Giving her this gift would definitely win the hearts of Yiren. Princess Yuzhen was determined not to give it to her, and Chen Wanrong had no choice.

After finishing work, everyone went home happily. Today is worth it!

This matter is basically over. Even if you have to make a telescope in the future, it will be no big deal. Chen Wanrong didn't take it much, but this matter was just an introduction.

The next day, Chen Wanrong met a historical celebrity who made him dazzled even if he thought about it, a great scientist who was well-known in Chinese history!

Chen Wanrong came to the Military Weapon Prison, and Ye Tianheng and the others squeezed into a room, each with joy on their faces, as if they were in the New Year. Chen Wanrong couldn't help but feel very strange.

"General Chen, you are here!" Kou Yibing greeted warmly: "General Chen, do you know? Yesterday the telescope invited us a famous master!"

"A master? How high can he be?" Chen Wanrong was a little distracted and thought to himself: "In terms of fists and feet, there are Taoist masters; in terms of skills, there are masters of military weapons; in terms of theory and me, there are really no ones who can be called masters."

It’s not Chen Wanrong Ao, but because the military weapon surveillance concentrated the best craftsmen of the Tang Dynasty, and the masters in the eyes of the world were not as good as they were.

Everyone moved aside. Chen Wanrong saw clearly and saw two strange faces in the room, one was a bald monk and the other was a middle-aged man. The most eye-catching thing was the monk's bald head, with a few scars that were particularly conspicuous, monk's robe, marble shoes, and typical monk's outfits.

The monk did not go to the temple to worship Buddha and ran to the military weapon prison, which was amazing. Chen Wanrong couldn't help but look at it carefully. The monk was in his thirties and forties, with a white face, a smile on his face, and his eyes were particularly bright, giving people a sense of wisdom when he blinked.

It can be said that he did not have the tranquility of a monk at all, and his whole body was shining with light. The middle-aged man next to him had a good temperament, but compared to him, he was quite inferior.

Chen Wanrong's heart was terrified. This person must be a very human being. What surprised Chen Wanrong the most was that the monk and Sima Chengzhen had a fierce fight. The two sat face to face, had a happy conversation, with a smile on their faces.

Sima Chengzhen stood up and smiled and introduced Chen Wanrong, "My friend, this is a line of masters. A line of masters, this is General Chen."

"Yijie? Monk? The author of the Dayan Calendar?" A series of question marks flashed through Chen Wanrong's heart: "I actually met the monk and his rank who enjoyed a great reputation in history?"

Although Monk and his friends are from Buddhism, they are an immortal monument in Chinese history! His achievements in astronomy and mathematics have attracted worldwide attention, which is modern times. When we talk about this outstanding scientist, we will always be respectful.

Chen Wanrong has heard of the name of monks and his shang countless times. After coming to the Tang Dynasty, he thought how good it would be to see him. However, this can only be a dream. The monks and his shang are indefinitely in their whereabouts, so it is so difficult to see him.

Now, the monk and his party appeared in front of him, smiled at Chen Wanrong, and bowed: "I have seen General Chen!"

Chen Wanrong's throat was dry and he said awkwardly: "Chen Wanrong has met the master!" He bowed deeply, and was extremely respectful.

Chen Wanrong wanted to tell him his favorite three ancient Chinese scientists, and the monks must be there. When he saw the monks, he felt aware of the feeling of admiring him.

The monk and his party smiled and introduced Chen Wanrong, saying, "General Chen, this is my monk's friend Liang Lingzan."

Chen Wanrong staggered and almost fell to the ground. A monk and his party were already exciting enough, and there was Liang Lingzan. Chen Wanrong's excitement was far beyond the description of his pen and ink!

Who is Liang Lingzan? A famous skilled craftsman!

The monk and his party made such brilliant achievements in astronomy and praised them for their praise. If it were not for Liang Lingzan, he would not have achieved so many achievements. The reason is that Liang Lingzan helped him well and helped him make astronomical instruments.

Wu Daozi's painting skills are unique throughout the ages and are regarded as the "painting saint" by later generations. It is hard for anyone to compete with him. However, Liang Lingzan's painting skills can be compared with Wu Daozi, and he was a famous painter in the Tang Dynasty.

What really made people remember Liang Lingzan was not his contribution to painting skills, but his being a famous manufacturer. In modern terms, he was a famous mechanical engineer. The "water armillary celestial sphere" he and his party jointly created was a unique astronomical clock in China at that time.

The monk and his side were ordered to observe astronomy, but there was no instrument that could meet his requirements at that time, and "no way to measure". The monk and his side learned and knew very well, but had no way to focus on it. It was really a skill of slaying dragons, but there was no dragon to slaughter.

Liang Lingzan was an amateur astronomy enthusiast. Based on his research on the experiences and lessons of his predecessors, he created the famous "zodiac sign". Of course, his manufacturing process was not smooth. After many failures, he used wood to make a model and finally made the astronomical instrument "zodiac sign" that is famous in astronomy history.

It was precisely this instrument that Monk and Hishang used this instrument to measure the degree of the twenty-eight constellations from the extreme north of the celestial sphere that first discovered the change in the position of the star, one thousand years earlier than Europe. Using this instrument, Monk and Hishang obtained a large amount of first-hand information. After calculation, the famous "Dayan Calendar" was born. It was later introduced to Japan, and it took Japan hundreds of years.

What is most surprising is that the water-transport amphibious celestial meter also has the function of timing. It is more exquisite and complex than the astronomical meter made by Zhang Heng of the Eastern Han Dynasty and has more functions. It is driven by gears, and there are two wooden men on it. In ancient times, one day and one night were divided into one hundred chasms. Every moment, the wooden men beat the drum and every hour, the bell was hit.

This is far beyond the scope of astronomical instruments, it is a mechanical clock!

The clocks we use today are all introduced from the West. In fact, as early as the Tang Dynasty, Monk Yixing and Liang Lingzan created the earliest mechanical clocks in human history. Unfortunately, they did not have a large amount of promotion, and they did not develop into clocks, which makes people sigh.

Liang Lingzan bowed to Chen Wanrong and said, "Liang Lingzan has met General Chen."

Chen Wanrong laughed loudly, and was very happy. He gave Liang Lingzan a bear hug, patting his back as if he saw an old friend, and asked anxiously: "Master Liang, are you willing to come to our military weapon supervisor?"

Military weapon supervisors are full of talents, but not many people can truly be called the one who can hold the beam. Ye Tianheng's skills are definitely one, but he is already old and has not had many days. Although there are many good military weapon supervisors, it is difficult to find someone who can replace Ye Tianheng. If Liang Lingzan, a genius "mechanical engineer", can join the military weapon supervisor, it would be perfect.

Now that the machine tool has been built, it is just in need of technical talents in this field. Chen Wanrong is familiar with machining but is not proficient. He cannot have time to let him study machining and pull Liang Lingzan over. This is Chen Wanrong's first idea.

"No matter what, you must get Liang Lingzan into the military weapon surveillance! You just kowtow, beg your grandpa to sue your grandma, and even cheat and cheat!" Chen Wanrong made up his mind in secret.

I won’t talk about the monk’s journey. Because of his profound knowledge, he is well-known and widely respected. However, he is engaged in astronomy and mathematics. Although he is a very useful person, it is a bit useless for Chen Wanrong.

Liang Lingzan is the most suitable one!

Employing people is not the best one, it is the most suitable one!

Not only Chen Wanrong thought so, but Ye Tianheng and others didn't think so? Ye Tianheng ticked his crutch on the ground and hurriedly said, "Master Liang, come to the military weapon prison! Ye is old and useless. In the future, you young people will have to rely on you!"

Kou Yibing and the others nodded violently and looked at Liang Lingzan nervously, fearing that he would not agree.
Chapter completed!
