Song Shixian led his disciples and dozens of craftsmen. Lin Fu asked Chen Enze to take care of everything, and temporarily placed the observation of the solar eclipse on the Haidong camp army's participation in the Goryeo Civil War.
After the banquet, everyone else dispersed. Chen Enze, the governor of Jeju, could not be careless. After asking his entourage, he found out that Song Shixian and Zhao Shuhan were heading to Mount Anlan.
Mount Anlan is a single mountain in the north of Jeju City, no more than forty feet high. However, when Lin Fu decided to order Song Shixian and Jiang Yue to take charge of observing the solar eclipse, he also ordered Jeju to prepare in advance and wait for Song Shixian to come.
That is to observe the solar eclipse.
Chen Enze has been in Haeju for the past month. Anlan Mountain in the north of the city is the location chosen by Jeju Magistrate Zhou Guitang to build a star observatory.
After disembarking, Song Shixian was dragged to Jeju City by Chen Enze, but his children and some craftsmen took several carts of observation instruments to the Anlan Mountain camp first.
Time is very tight. In addition to observing the solar eclipse, we must further observe the celestial bodies and stars to prove the "shifting of stars".
The so-called "stars move around" actually happened more than a thousand years ago when Luo Xia Changgong, the master of astronomy and calendar in Langzhong, summed up the experience of his predecessors in astrology and realized that as time goes by, the relative positions of the stars on the whole picture (i.e. the star catalog)
It is a phenomenon that the position changes; therefore, for thousands of years, literati and poets have often used "the stars move around" to describe the changes in time and the passage of time.
In addition to the time factor, as the north and south directions differ, the positions of the stars on the Humxi star chart will actually change. Currently, merchant ships on the Huaidong Sea traverse the East China Sea, and the astrological technique used in Nanyang to compare the north and south directions originated from this principle.
.
When Song Seok-heon and the others came to Jeju this time, they also wanted to observe whether there would be any "star shifting" phenomenon at different observation points in the east-west direction.
Although the astronomical observation methods at that time were still quite crude, and solar eclipses were only observed visually, for the observation of stars, precise armillary spheres could be produced several dynasties ago, which could accurately establish the calendar of that year.
.
Jiang Yue became famous all over the world for presiding over the construction of the Armillary Sphere.
The armillary sphere he supervised can be said to be the culmination of astronomical, calendar and mechanical manufacturing in history. It is ten feet high and consumes hundreds of thousands of kilograms of copper. The star table and instrument rings are all driven by running water - but Jiang Yue is not studying in miscellaneous studies.
In terms of craftsmanship, his various contributions to Huaidong, including his supervision of the creation of the armillary sphere, were enough to put him at the top of the world's craftsmen.
When Yanjing fell, there was an armillary sphere nearly ten stories high. Naturally, there was no way to move it from Si Tianjian's observatory and fall into the hands of Yan Hu.
However, Jiangning is the companion capital of Yuan Yue, and it also has six central temples and nine temples. Jiangning Sitianjian is also operating normally.
Although Jiangning Sitianjian does not have a large and precise armillary astrology instrument like that of Yanjing, it does have two bronze instruments inherited from the previous dynasty, both of which are more than ten feet long. People can place them in them to observe the stars. Although Jiang Yue, Song Shixian, etc.
People intend to build a super-large armillary sphere, but they have never had the energy. The two small ones are not too small to say the least, and are enough to meet the current needs of spiritual cultivation.
This time Song Seok-heon plans to permanently install one of them on Mount Anlan in the north of Jeju City for star observation.
Chen Enze came to Anlan Mountain in a carriage. Song Shixian could not wait to ask his disciples to install the armillary sphere overnight on the observatory where the stone foundation had just been laid. The installation and adjustment of the armillary sphere was far from being successful in one day. It fell on the stone platform first.
Set up a telescope.
When Chen Enze climbed Mount Anlan, Song Shixian was about to take Zhao Shuhan with him to observe the stars through a telescope...
"Lord Governor, we are here too." Zhao Shuhan watched Chen Enze coming on stage and bowed in greeting.
Faced with Zhao Shuhan's small-wing attitude, Chen Enze felt uncomfortable. When Zhao Shuhan was invited by Lin Fu to teach miscellaneous studies at Jiangning Zhutang, Chen Enze, Hu Qiaokou, Hu Qiaozhong, Cao Ziang's son Cao Wenlong and others were still young at the time. In fact,
They also learned the basics of miscellaneous studies from Zhao Shuhan.
Before the estrangement arose due to political differences, Lin Fu regarded Zhao Shuhan as a friend. How could Chen Enze and others not regard Zhao Shuhan as their teacher?
However, times have changed and Chen Enze was only twenty-eight years old at the time and already occupied the high position of Governor of Jeju Prefecture. Zhao Shuhan chose to self-exile to Haeju and only held the idle position of counselor in Jeju Governor's Mansion, standing together with Chen Enze.
It turned upside down.
Chen Enze said with a smile: "I just wanted Master Zhao to bring Scholar Song here." He looked at the more than one meter long telescope mounted firmly on the stand and said to Song Shixian, "I am in Haizhou. I heard that there is a
Stargazing telescope, I didn’t expect it to be actually made..."
"The double mirrors were polished with water jade by the old engineer Ge himself. I made two of them, and I took one to Jeju." Song Shixian said.
Chen Enze wanted to eliminate the embarrassment between him and Zhao Shuhan, and deliberately pointed to the telescope and asked: "Master Zhao, does he know what this mirror is?"
"It is said in Western countries that there is a magic mirror that can make distant mountains and rivers appear as close as before," said Zhao Shuhan, a scholar of heaven and earth. Although he had not yet stood in front of the telescope to take a closer look, with his extraordinary knowledge, he talked about it, "Just now, the scholar of the Song Dynasty
It is said that this mirror cannot see the sun, and the sun will be like burning, and it will be blinded for a long time. It is also said that this thing is made of water jade, and white glazed glass can also be made. - "Huainan Wanbi Shu" of the former Han Dynasty records: "Peel the ice to get it"
The method of fire, and the previous "Su Chen Liangfang" also recorded the methods of using fire, saying: "Anyone who wants to make fire should knock a stone to get the fire, or use a water jade mirror to get it from the sun, the sun's fire is the best"; the previous "Su Chen Liangfang" also records the methods of using fire.
"Chen Shu" records, "There is a country of Borno in the southeastern sea. It produces fire beads. The big ones are like chicken eggs, and the oblate ones are like water jade. If you use moxa to carry it in the middle of the day, you will get fire. If you put it on the word "ant", you will see it like a fly."
Known as Zhaoxia Huozhu, it later entered the Champa Kingdom and was regarded by the nobles as a treasure in the world... And its various wonders that the world did not notice were called "Xu Tou Xiang Ju" by Zhao Youqin, a Jinshi during the reign of King Sejong, in his "New Book of Ge Xiang"
That's why. The "Book of Mozi" also said, "The person of light is as warm as a shot"..."
Zhao Shuhan's words not only moved Chen Enze greatly, but Song Shixian also bowed his head and prostrated, saying: "People in Jiangning say that I stole Brother Zhao's position as a bachelor, and I feel quite dissatisfied. After hearing what Brother Zhao said today,
, I was convinced and returned to Jiangning. I resigned my position as a bachelor to Duke Chongguo and let Brother Zhao take over..."
Song Shixian's words were completely made by a scholar who did not consider his political views, and Chen Enze did not care about him. However, Zhao Shuhan's words really explained the principles of optics thoroughly.
"A person of light is as bright as a shot", translated into a more popular language, it means: "The light shining on a person is as straight as an arrow." To make fire by cutting ice or using a jade (crystal) mirror, it is actually a convex lens.
The function of converging light can be clearly explained by the predecessor Zhao Youqin in the simple four words "Xu penetrates the gathering" - "Xu" means sunlight, and when placed on top of the word "ant, look at it like a fly", it means
The magnifying effect of a semi-convex lens or a convex lens.
These various optical phenomena and the principles behind them have actually been recorded and thought deeply by the ancients for thousands of years. It is just a pity that these trickle-down thoughts have not been systematically summarized and speculated on.
Including the prototype of the telescope, it has actually been circulated in Thailand for a long time, but the country used it as a magic mirror to confuse people in drama performances, and it has not yet been used for military, astronomical observation and other practical purposes. On the contrary, the wealthy people in the Jianghuai period
, there are magnifying glasses ground with jade so that the blind can see.
The reason why it is so difficult to go from a magnifying glass to a telescope is that it is very difficult to grind two lenses with the same focal length and curvature. It is very labor-intensive and labor-intensive. It took many years to cultivate more than a dozen skilled grinders.
Fortunately, the telescopes made by mirror craftsmen are very practical and there is a huge demand, so we can continue to improve the mirror grinding technology and cultivate more professional craftsmen.
It was only in the second half of last year that the Huaidong Army began to grind a small batch of monocular telescopes, which can see fine objects three to five miles away. However, the requirements for telescopes that can really be used for observing stars are higher and more demanding.
Recently two more have been built.
Zhao Shuhan was able to figure out the truth based on the shape of the telescope he saw - he was actually one of the three or five people who were experts at the World Expo and were good at reasoning.
It would be an extraordinary pity if such a person could not serve the new empire.
Of course Zhao Shuhan understood why he couldn't be admitted to the Chongxue Hall. He told Song Shixian without any thought, which made him even more embarrassed in front of Chen Enze. He thought to himself that what he just said had some obvious traces of showing off, but he didn't know that it had spread to Lin
What does it make people think when they are bound in their ears?
Song Shixian devoted himself to studying miscellaneous studies and was not familiar with secular affairs. He said to Zhao Shuhan: "Brother Zhao should remember that "The yin of the year is at noon, and the stars are in the unitary unit, and the fifth month is in the stomach, and it is in the morning."
"Enlightenment" or something like that?"
Asking Song Shixian to stop talking, Zhao Shuhan asked: "Does Scholar Song want to observe the Sui star?" The passage Song Shixian just recited actually refers to the position of the Sui star in the sky in May. Only Zhao Shuhan is so knowledgeable.
People who have a strong memory can understand quickly.
"Of course," Song Shixian said, "then Brother Zhao still remembers the words of the Sui Xing recorded by Qu Tan in the "Kaiyuan Divination" of the previous dynasty?"
Except for Zhao Shuhan, there are really not many people in the world who can keep up with the isolation of previous book editors mentioned by Song Shixian. Of course, Zhao Shuhan can know that it is very important to sort out the world's canons and compile the "Jiang Dian" with him in the past ten years.
relationship, he recalled for a moment and recited the sentences about the year star in the "Kaiyuan Divination Scripture" almost exactly, "The "Kaiyuan Divination Scripture" said: In the year of Shan Juan, the photo taken by Tige is in Mao, and the year star
In Zi, with Xu Nu, Xu, rising in the morning and coming in at night, its appearance is very bright and bright. If there is a small red star attached to its side, it is called an alliance... Is Scholar Song going to look at this small red star with the help of a telescope?
?”
The Sui star is the Jupiter that is familiar to later generations. It is the brightest star that can be seen with the naked eye in the night sky. However, Jupiter is not a lone star. In the dark place of the starry sky, there are many satellites surrounding Jupiter. Ancient people with good eyesight could only
A small red star can be vaguely seen, which is called an ally of Jupiter.
Although there is still half a month to observe the solar eclipse, Song Shixian, Jiang Yue and others have actually overturned the old theory that the sun, moon and stars move around the earth and through the sky. The basis is to use this one-meter-long observatory.
Observation of the Year Star with a Mirror.
In addition to the "Little Red Star" recorded by their predecessors, they also clearly saw four other small stars moving around the Sui Star - this alone can prove that the place where they are standing is not the only center of the stars in the sky.
It has directly shaken the old theory of "the heart of the sky and the earth"...
Lin Fu did not call Song Shixian for this conclusion, Jiang Yue and others were anxious to announce it.
After all, there are only two large stargazing telescopes at the moment. Publicizing the conclusions through the Di Bao will only cause fierce quarrels. Confucianism was established as an official school and used by the emperor's family. It began in the Early Han Dynasty and its status has been consolidated for more than a thousand years.
, where is it so easy to be shaken?
The observation of solar eclipses is something that many scholars and the general public can participate in; there will be time deviations in the occurrence of solar eclipses in different locations, which will be witnessed by many scholars and the general public.
Even if there are some stubborn people who won't believe it even if they see it with their own eyes, there are bound to be people who believe what they see with their own eyes.
Song Shixian had a conversation with Zhao Shuhan at the banquet and saw that he had almost independently deduced the solar eclipse and jet lag. When he met a close friend who could match him, he naturally couldn't wait to drag him to the observatory to observe the stars.
A disciple compared the Huxian star chart and pointed the telescope at the direction of the Sui star. Song Shixian motioned to Zhao Shuhan to go over and look at the Sui star first.
Zhao Shuhan had always remembered the little red star beside the Sui Star recorded by his predecessor Qu Tan, but he did not have a pair of naturally gifted eyes. He watched the stars many times at night, but he could not see the little red star. In fact, this little red star
The red star is just a legend for many years. Orthodox Confucians will never admit the existence of satellites in the Sui Star. However, the predecessor Qu Tan recorded this little red star and cautiously called it the "alliance" of the Sui Star.
Looking at the stars in the sky, and having a stargazing telescope, Zhao Shuhan couldn't wait to see the stars more clearly. With the help of Song Shixian and his disciples, he fine-tuned the telescope to see the stars and took a closer look.
, I was stunned there. In addition to the legendary Little Red Star, there were also three small stars clearly visible beside the Sui Star...
"How?" Song Shixian was quite proud of Zhao Shuhan's shock. He saw four small companion stars beside the Sui Star more than half a month ago, and his heart was filled with waves.
Seeing that Zhao Shuhan was silent, Chen Enze walked forward and saw his cheeks covered with crystal tears, and softly shouted: "Master Zhao..."
"If you hear the truth in the morning, you will die in the evening," Zhao Shuhan turned to look at Chen Enze, put aside all worldly fame and fortune, and said, "I would like to ask Enze to send a message to my old friend. Zhao Shuhan only wants to stay at this star observation platform in his life!"
