"This meaning is easy to understand. Tongshan collapses in the west, and Luo Zhong responds in the east. It is not distant but yin." [Yuewei Thatched Cottage Notes Volume 13]
"The same is true between the harp and the harp, and the same is true between the harp and the harp. The sounds are harmonious and harmonious with each other, and they resonate and increase the sound. The "Poetry" says, 'The sound of the zither and the zither, the sound of the Suyong and the harmonious sound' is what it means." The emperor saw. Looking at Ma Jun, who was still in shock, he said calmly, but in his heart he was satisfied with the taste of the preaching professor.
Liu Wan did not come from a poor family like Ma Jun. He did not read books since he was a child. Even when he finally bought a copy of "The Classic of Filial Piety" and held it in his hand as if it were a treasure, he found that there were errors and omissions in the words. Liu Wan's father was Zeng and Da General Dou Wu planned to kill the famous official of the eunuch, and the minister Liu Yu was a descendant of King Jing of Guangling. His family had a collection of treasures, and he had been involved in extensive knowledge since he was a child. After watching the piano master's demonstration just now, how could I not know that this scene is from "Zhuangzi" s story?
Although he didn't quite understand what the emperor meant by doing this, out of the basic qualities of an official, he still echoed a few words: "What your majesty said is quite reasonable. I hope you can learn from it."
The emperor glanced at Liu Wan and seemed not very satisfied with the other party's response. Fortunately, his expectations were not placed on Liu Wan, but on Ma Jun.
"But I, I don't understand." Ma Jun is not like Liu Wan or Zhang Gu who understands the ways of the world. Instead, he has a kind of simplicity. His voice is not loud, as if he is talking to himself: "Why does one string move, and the other string moves?" The string rises, how can there be resonance between the two?"
Liu Wan was shocked. He didn't expect Ma Jun to be so honest. If this question stumped the emperor, wouldn't the emperor be very embarrassed? As for what sounds are produced and how they are transmitted, the ancients have never done anything in this regard. Doing very in-depth research, they often associate it with unknown "weird powers and chaotic gods". Even so, if Liu Wan hadn't read many Yin-Yang and Taoist miscellaneous books, those Confucian scholars who only studied orthodox classics would probably have been twice in a row. I don't even know the allusion to "Qin Resonance".
He was afraid that the emperor would not be able to answer and would only cause trouble, so he had to speak first: "When I heard about Emperor Xiaowu, the bell in the front hall of Weiyang Palace rang for no reason and kept vibrating. So I issued an edict to Taizhong's official Dongfang Shuo, who said: ' Copper is the son of the mountain, and the mountain is the mother of copper. In terms of yin and yang energy, the son and the mother are aware of each other. The mountain is afraid of collapse, so the bell rang first. In the next five days, there was a landslide somewhere. It can be seen that the yin and yang are intertwined. Qi enables the two to communicate with each other even though they are far apart, and the harp and zither have the feeling of husband and wife, which is exactly what it means."
Ma Jun looked astonished. The ancients believed in the theory of ghosts, gods and yin and yang, not to mention that this was the Han Dynasty when prophecies were very popular. Even Ma Jun, who was practical and studied the investigation of things, was not immune for a while. He looked like he had been tricked by Liu. Wan was convinced.
This look in the emperor's eyes made him a little unhappy. He originally wanted to use this to arouse Ma Jun's interest in exploring the principles of acoustics, but unexpectedly the clever Liu Wan diverted the topic halfway, and he almost wanted to Ma Jun led Wei Xin to him, how could the emperor be willing to accept this? He glanced at Liu Wan with feigned anger, which made him shrink his neck in fear and not dare to continue speaking.
Then the emperor leaned up and turned a deaf ear to what Liu Wan said. Gu Zi said to Ma Jun: "The fact that you can ask this question shows that I have not misjudged you. As for what you are asking, you must first know why. An object must be struck and plucked before it can make a sound? You might as well think about it for yourself after you go back. Only when you understand this principle can you know how to resonate."
"I promise." Ma Jun hesitated for a moment and promised with full of questions.
Ma Jun was actually a very smart man, but his intelligence was not reflected in his attainments in Confucian classics or his ability to govern the country, but rather in the technical field. In the emperor's view, he did not lack the skills to govern the country.
What is lacking among great talents are scientists like Ma Jun who can improve production technology and productivity. To improve productivity in a long-term way, it is not just about developing a few machines. The key lies in the most basic scientific theories and principles.
This is also the purpose of the establishment of Gewuyuan.
The emperor planned to gradually inculcate the way of thinking about exploring the principles of things from the two generations of Han Ji, Ma Jun, and Zhang Gu, hoping to explore a complete scientific theoretical system. As long as this system is in place, coupled with appropriate
The system can cultivate an endless stream of scientific research talents for the world, and new technologies will spring up like mushrooms after a rain, instead of relying solely on the emperor to passively promote them with the knowledge of future generations.
Acoustics is the most basic and simplest subject in physics. The emperor planned to start from this point and try Ma Jun and others' abilities first.
After saying this, the emperor looked at Liu Wan again. Liu Wan was shocked by the emperor's words to Ma Jun, "I have never wronged you." He really didn't expect that Ma Jun still had such a status in the emperor's heart. No wonder this time
He was specifically asked to meet him by name. The group of subordinate officials at Lingtai who were trying to seduce others were just confused, and they almost caused him trouble. Fortunately, Liu Wan thought that he was fair in dealing with things and did not feel sorry for Ma Jun. There was still some way to remedy the situation.
Countless thoughts flashed through Liu Wan's mind. At this moment, he heard the emperor say: "The story you just told about Dongfang Shuo can be used as evidence. Since it will be heard of a distant landslide five days later, depending on the speed of local transmission,
, it took many days on the road, and it can be seen that there was a landslide first, and then the bell rang. The sound of the landslide caused the copper gun to vibrate, and it was still used to warn the seismometer this time. Is it not the sound of the earthquake that made the instrument automatic?
"
Ma Jun, who still had a doubtful expression on his face, suddenly felt enlightened after hearing this. He seemed to have grasped something from the examples mentioned by the emperor, as if a closed door had finally been pushed open, and his eyes suddenly opened up and became colorful.
Unlike Ma Jun, who was obsessed with the "law of all things", Liu Wan was more inclined to understand the deep meaning behind the emperor's words just now. The emperor's words seemed to vaguely explain why the seismograph moved, but in fact, they blamed everything on
The unknown was discovered, and this "unknown" was left to Ma Jun to explore by himself, which made him puzzled.
Of course, the emperor did not expect Liu Wan to understand anything. It was not yet known whether the seismograph was effective, and he did not take it too seriously. The emperor could not be completely convinced by just a few records in the history books, and even if it was useful,
There are also problems of practicality and popularization. But since there are old objects developed by Zhang Heng at this time, and there are oral deeds passed down by the old people who witnessed the seismograph, it might as well let Ma Jun do some research.
Even if it cannot be restored to its original state, or the function after restoration is not satisfactory, or not as miraculous as praised in history books, Ma Jun can further deepen his understanding of the machine spring and instrument manufacturing by studying the internal structure of this instrument;
Learning from the wisdom of the predecessors is what the emperor really wants to see.
As for why the seismometer suddenly took effect this time, the emperor did not want to speculate too much on it. Maybe it was just a coincidence, or maybe.
