This principle is explained clearly, which is helpful for them to understand in order to make better telescopes. This is very necessary. Chen Wanrong sorted out his thoughts and said: "This requires two lenses. The front one is called the objective lens, which is used to capture the distant objects." The scenery is condensed into light, but with only an objective lens, you can only see an inverted virtual image."
"Inverted? Didn't we see it standing upright?" Everyone almost jumped up in surprise.
"You try it with a piece like this." Chen Wanrong reminded them by shaking the convex lens.
The people with the convex lenses in their hands immediately started experimenting and exclaimed in unison: "General Chen, why are you so young? Are you really standing upside down? No, you are obviously standing, so why are you standing upside down again?"
They are facing Chen Wanrong. If not Chen Wanrong, who else can they test?
Looking at their shocked expressions, Chen Wanrong smiled and said, "Try putting another lens on a line."
Everyone obeyed, and the sound of surprise rang out again: "It's true! General Chen is standing again!"
The health workers screamed the loudest, as if they had seen the most magical thing in the world.
Ye Tianheng slammed the crutch in his hand on the ground and said: "Little friend, I understand! I really understand!"
He looked like he was suddenly enlightened. Chen Wanrong considered him carefully and said with a smile: "I would like to hear Master Ye's advice."
"I can't say that I have high opinions, I can't say that I have high opinions!" Ye Tianheng stood up with a smile and said: "To put it bluntly, it's very simple. The difficulty is that we don't have such tools. Now that we have lenses, it will be easier. Any of you? How many people have read "Mozi"? Mozi had tried pinhole imaging back then. Mozi used pinholes, but we use lenses today, so the principle should be similar."
It was the first time in human history that Mozi and his students conducted a small hole imaging experiment. "Mozi" records many scientific experiments, which can be called the pinnacle of ancient Chinese science and technology history. Regrettably, due to many reasons, progress in physics has stalled since then.
Small hole imaging is similar to imaging with a lens, but the methods are different. With his reminder, Kou Yibing, Liu Huaide and other good workers who were familiar with "Mozi" suddenly realized and nodded in agreement.
Those students had not been in the Ordnance Supervision for a long time. What they learned in the Imperial Academy was the way of saints and they read the books of sages. They were not familiar with "Mozi". They were stunned for a while, not knowing why. .
As soon as Chen Wanrong started, Ye Tianheng thought of it. Due to his quick reaction, Chen Wanrong had to admire: "Master Ye is very right. There are some similarities between the two. The difference is that we are now Just use a lens.¡±
After receiving the approval, Ye Tianheng was even more sure: "Mozi's small hole image is an inverted virtual image. 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." , people can see it clearly at a glance, and don¡¯t have to think about the whole story anymore!¡±
Chen Wanrong clapped his hands and praised: "What Master Ye said is absolutely true. This is the truth of telescopes!"
Ye Tianheng understood another scientific and technological principle. He was very excited, his throat was a little dry, and he said awkwardly: "My friend, if you have any other requirements for this telescope, you have to tell them all. Only if you tell them thoroughly can we make them!"
Before Chen Wanrong could speak, Zheng Wanru stood up suddenly and said, "I understand too. Han Fei once recorded a story about a man who asked a painter to paint for him. Three years later, the painter told the man, The painting was finished. When the man went to see it, there was only a big wooden board with nothing on it except paint. The man got angry and said that the painter had lied to him. The painter said, "You want to see a living, moving painting?" Huh? All the paintings in the past were dead and lifeless. This person 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 big window on the wall. Put the wooden boards Put it on the window, and when the sun comes out, you can see a painting, a moving painting.
"Under dubious belief, this man actually built a house with one wall. When the sun came out, pavilions and pavilions appeared on the wall, as well as carriages and horses passing by, making it look like a gorgeous and colorful landscape painting. What¡¯s even more surprising is that the characters, carriages and horses in the painting can move. The only regrettable thing is that they are all upside down.¡±
Han Fei is a master of Legalism. Although his books were written for Legalists, there are many popular allusions in his books that are widely circulated. Although the students in the Imperial College are practicing the ways of saints and reading saints' books, there are also some who read "Han Fei" for fun. When they heard this, they all exclaimed in unison, "Oh, why didn't I think of that?"
With Chen Wanrong's theoretical guidance, Ye Tianheng and Zheng Wanru told allusions one by one. The atmosphere was very different. It suddenly became lively. Even Jin XianLiang Lingzhan was originally an amateur astronomy enthusiast. Based on studying the experiences and lessons of his predecessors, he created the famous "Ecliptic Orbiter". Of course, his manufacturing process was not smooth sailing. After experiencing many failures, he made a model out of wood, and finally made the "Ecliptic Orbiter", an astronomical instrument that is famous in the history of astronomy.
The monks and his party used this instrument to measure the degree of the twenty-eight constellations from the extreme north of the celestial sphere. They discovered the changes in the positions of stars for the first time, a thousand years earlier than Europe. Using this instrument, the monks and his party obtained a large amount of first-hand information. After calculation, the famous "Dayan Calendar" was born. It was later introduced to Japan, and Japan used it for hundreds of years.
The most surprising thing is that the water-borne armillary sphere also has the function of timing. Compared with the astronomical instrument made by Zhang Heng of the Eastern Han Dynasty, it is more sophisticated and complex and has more functions. Driven by gears, there are two wooden figures on it. In ancient times, day and night were divided into one hundred quarters. The wooden figures beat the drums every quarter and struck the bell every hour.
This is far beyond the scope of astronomical instruments, it is a mechanical clock!
The clocks we use today are all imported from the West. In fact, as early as the Tang Dynasty, Seng Yixin and Liang Lingzan created the earliest mechanical clock in human history. It's a pity that it was not widely promoted, let alone developed into a clock, which makes people sigh with regret.
Liang Lingzhan saluted Chen Wanrong and said, "Liang Lingzhan has met General Chen."
Chen Wanrong laughed loudly and was very happy. He gave Liang Lingzhan a bear hug, patted him on the back as if seeing an old friend, and asked eagerly: "Master Liang, are you willing to come to our weapons inspection?" ?¡±
There are many talented ordnance supervisors, but there are not many who can truly take the lead. Ye Tianheng's skills are definitely one of a kind, but he is already old and his time is running out. Although there are many good people in the Ordnance Supervision, it is really difficult to find someone who can replace Ye Tianheng. It would be perfect if Liang Lingzhan, a talented "mechanical engineer", could join the Ordnance Supervision.
Now that the machine tools have been built, technical talents in this area are needed. Chen Wanrong is familiar with machining but not proficient in it. It is impossible for him to have time to refine machining. Pull Liang Lingzhan over. This is Chen Wanrong first thought.
"No matter what, we must get Liang Lingzhan into the military equipment prison! We don't hesitate to kowtow, beg grandpa to sue grandma, or even deceive and abduct him!" Chen Wanrong secretly made up his mind.
The monk will not say anything else. Because of his profound knowledge, his reputation spread far and wide and he was widely respected. However, he is engaged in astronomy and mathematics. Although it is very useful, it is somewhat useless to Chen Wanrong.
Liang Lingzhan is the most suitable!
Hiring people is not about hiring the best ones, it¡¯s about hiring the most suitable ones!
Not only Chen Wanrong thinks so, but also Ye Tianheng and the others don¡¯t think so? Ye Tianheng's crutch moved on the ground, and he hurriedly said: "Master Liang, come to the weapons inspection! Ye is old and no longer useful. From now on, I have to rely on you young people!"
Kou Yibing and the others nodded fiercely and looked at Liang Lingzhan nervously, for fear that he would not agree. (To be continued.
