Chapter 455 Balance Ring
The light screen that had turned black after the previous broadcast ended slowly lit up again.
Feeling the tension of Guanyin Bi, Li Shimin smiled softly and pinched the queen's wrist and said:
"It will be fine."
This time, Li Shimin suddenly had the idea to summon the queen to watch together. First, because all the generals went west to pacify Tuyuhun, making the Ganlu Palace empty.
Secondly, because the things presented to the future generations this time were presented by the queen, Li Shimin brought her to watch together.
Although the Queen Changsun also watched half of the show because of the last time when His Majesty fainted, she was still nervous at this time.
Looking carefully, I saw that the things that were still playing in my palm yesterday have now turned into a vivid picture on the light screen.
[Hello, hello, Illiterate people wish the audience a happy new year first!
The closer it is to the end of the year, the busier it is, but even so, the rewards from the big guys have never been absent, so I have to compare my heart here.
The copybook is very good, and the content and signature are very interesting. I feel that in two months, the UP host can hold an exhibition of calligraphy by celebrities from the Three Kingdoms, but it will probably be exposed as fake.
Another thing is obviously a replica of a national treasure from the Tang Dynasty. If it were in the Tang Dynasty, I would say it is ingenious, but if it were in modern times, I can only say it is 3D printed YYDS! 】
Li Shimin looked at it intently and saw the conspicuous copybook at the first time.
The four characters "Wei En Da Xing" were written on it, and the signature was as expected:
"Lu Su, East City of Linhuai, Spring of the Eighteenth Year of Jian'an."
There is also a small private seal next to it.
Seeing that there is no official title in the signature, Li Shimin sighed and said:
"I got Lu Su."
Based on what Wu Hou said and the things he gave to later generations, although it can be roughly inferred that this is a completely different war trend from the Three Kingdoms, every time he saw such things with his own eyes, Li Shimin still felt like a dream.
But every time this visible but untouchable light curtain in front of him also reminded him that everything he saw and knew was true.
It was also because of this that Li Shimin became more and more curious about the experience behind the scenes of Wu Hou Jian Guang.
As for the other thing, Li Shimin was already very satisfied to get a comment of exquisite craftsmanship from the younger generation.
〖Good guy, Lu Su personally wrote the words "Wei En Da Xing", the boss really knows how to do something.
Sparrow food, after all, I just said in the last issue that the horizontal scroll of the memorial archway of Lu Su's tomb was these four big characters, I didn't expect it to be done now.
But don't say it, don't say it, this handwriting is completely different from the previous Zhuge Kong Ming's handwriting, the boss did a lot of work.
Good reviews for the work, bad reviews for Xuan paper, the earliest appearance of this thing can be traced back to the Tang Dynasty Li Zhi period, Lu Su must have never seen it, but of course, Lu Su has never seen his own tomb either.
Alas, it would be great if there was Xuan paper in the Han Dynasty, after all, this thing is really durable compared to hemp paper, if there was Xuan paper in the Han Dynasty, our country would probably have a lot more national treasures.
Just think about it. It is too troublesome to make rice paper. In the Ming Dynasty, the rice paper craftsmanship was perfected. It required adding alkali and high temperature to steam the raw materials. After it was made, alum was applied to turn the raw rice paper into cooked rice paper. If you really want to travel through time, I suggest you add oil and make soap. It is much more fragrant than rice paper.
Good guy, I am off topic in daily life. Then I can only ask what this exquisite workmanship is?
The name of the museum should be the silver sachet with grape, flower and bird patterns. This thing is indeed a black technology in the Tang Dynasty. After all, the constant balance bracket was not available in the West until a thousand years later.
The diameter of this thing is only four and a half centimeters. The craftsmen of the Tang Dynasty were able to build two layers of concentric machine rings connected by double axes inside. The outer wall machine ring gold incense pot was connected with rivets. Free rolling can also ensure that the spices inside will not spill. It is not an exaggeration to say that it is exquisite workmanship.
Correction, according to the "Xijing Miscellaneous Records", this thing existed at least during the reign of Emperor Wu of the Han Dynasty, but it could not be made so small at that time. It was used as an incense burner in the quilt.
This thing is actually quite complicated to say. After all, it looks very powerful, but it seems to have limited application. First of all, this kind of thing that can rotate freely but ensure that the direction remains unchanged is called a balance ring in modern times. After being introduced to the West, two important things were derived from this important base structure.
One is the universal joint made by Hooke in the 17th century, which allows the lever to rotate in any direction. It is the most important basic transmission structure of vehicles today.
The second is that in the 19th century, Foucault combined the gyroscope and the balance ring to invent the gyroscope. Not to mention this thing, after hundreds of years of development, from aviation and navigation to aerospace, gyroscopes can be said to be used in all aspects of life.
I don’t understand so much, I just want to ask if this thing is expensive?
It’s hard to say whether it’s expensive or not, but if the one in the UP’s hand is real, it can only be said that it is conservatively estimated that you will not have to worry about food and drink in this life. 〗
Du Ruhui and Fang Xuanling’s eyes lit up, and they hurriedly recorded it with pens.
Yan Lide felt for the first time that the director of the work might have to try to split it, otherwise the things that need to be done would be too busy.
Yan Liben didn't care about the sachet, but he looked at the rice paper and felt a desire for the first time:
The work can be immortal for thousands of years!
I wonder if I can ask His Majesty for it? But thinking of the hilarious picture that His Majesty picked up from him last time, Yan Liben was a little embarrassed.
Li Shimin saw the reaction of the ministers, and although he didn't understand what he said later, he still simply and roughly summarized the characteristics: infinite uses!
If it weren't for the presence of all the ministers in Ganlu Hall, Li Shimin would have wanted to take Guanyin's maid and turn her around three times to vent his excitement.
This thing existed in the Han Dynasty, so what? After all, it was my queen who had a keen eye for clever things, and today I know that this is a thing that will last for generations.
...
Kong Ming didn't care so much, but for the first time since he saw the Guanyin Curtain, he had a complaint:
"With such a wonderful use, why not show a picture!"
But this sentence is actually just a complaint. After all, I am lucky to have a light curtain, and I am even more lucky to know that it has a similar effect to the incense burner.
It's just that it feels like peering into a treasure mountain through a door, knowing its benefits but not being able to access it. It can be said to be a heart-wrenching feeling.
Gonggong carefully copied down the casual remarks of these juniors. Kong Ming first sighed, feeling that this balance ring was very similar to what he felt now.
He had obviously made it for nearly a thousand years, but he had never been able to get in. He knew what it was, but he didn't know what it was. As a result, someone else made the key and entered the treasure mountain.
“Could it all rely on axiomatic thinking?”
Kong Ming immediately remembered what later generations said about "Elements of Geometry". Now it seems that these ingenious engineering creations are indeed not as important as scientific classics.
But after all, the world has not yet been settled. If you want to find the "Elements of Geometry", if you want to build a ship and send envoys to the west, and take the classics back to China, you still need to spend a lot of energy and time.
Compared to Kong Ming's thoughts, Pang Tong gently tugged on his beard, his face full of interest:
"Alkali added to soap?"
"This thing is easy."
As someone who was determined to catch up with Kong Ming, Pang Tong had basically been to all the workshops in Chengdu. Among them, there were complex ones such as papermaking and iron smelting, but there were also simple ones such as alkali making workshops.
Nowadays, there is no need to control military strategy as it was in Yongliang. Pang Tong expressed that he wanted to imitate Kong Ming and try to see if he could create what later generations would say.
He, Pang Tong, should also be diligent in engineering.
