Chapter 852 Daming Citizen ID Card (Please subscribe!)
As the most famous scientist in the new Ming Dynasty, he was called to the imperial study room by Zhu Kezang today.
Huang Luzhuang knew that His Majesty the Emperor must have something new.
This made him look forward to it.
Zhu Kezang felt that the Daguerreotype camera technology was of little use except for commercial use, unless its exposure time and cost were improved.
Daguerre's daguerreotype method was too expensive to be used on a large scale.
What Zhu Kezang envisioned was to combine photography technology with the Ming Dynasty household registration system after reducing time and costs!
In this way, all the people of the Ming Dynasty can carry their own ID cards when they go out.
It became very difficult for the spies of the enemy country to enter Ming Dynasty.
But the first thing is to improve the technology.
Zhu Kezang handed over to Huang Luzhuang a pamphlet full of Daguerreotype camera technology.
Huang Luzhuang knew that there must be something good to study.
He was delighted to see Lie Xin, and he kept flipping through it. Huang Luzhuang read it very carefully, and he refused to commit a single word.
"Fantastic imagination, Your Majesty is a great talent!"
"This is completely a soul-hunting technique!"
An hour later, Huang Luzhuang threw himself to the ground in admiration.
"Old Huang, you read it too. I am going to develop a new technology that can quickly record a person's appearance. You have to make this thing."
Zhu Kezang pointed to the core technology and continued: "But the cost of time and raw materials is relatively high. You can take Gewu Zhizhi Academy to find a way to solve these two problems!"
Huang Luzhuang felt great pressure. This is a field he has never challenged: the field of chemistry.
His hand holding the drawing is trembling now. The ancients had a natural fear of this kind of thing. If it were made, it would probably cause panic among the people.
Huang Luzhuang himself is not afraid.
"Your Majesty, can this camera really record a person's appearance completely?"
Huang Luzhuang couldn't help asking.
"Of course, not only can it be recorded completely, but it can also be developed through film and turned into a painting. However, this painting will be very detailed, more detailed than any other painting, just like you are looking in a mirror."
Zhu Kezang replied.
"Your Majesty, I'm afraid this camera won't be very useful after it is made. Firstly, the common people may not be able to accept it. Secondly, only dignitaries and merchants consume it. I'm afraid the economic value of this thing is not great."
Huang Luzhuang said in a deep voice.
His analysis can be said to be very realistic.
Huang Luzhuang is only limited by the knowledge of this era, and he doesn't see how great the role of cameras will be in the future.
"Old Huang, who told you that I'm going to sell it? Not only is this thing not for sale, but every camera must be strictly controlled, and every film must be strictly recorded!"
"After you improve the camera, you have to take pictures of every citizen of the Ming Dynasty, and then use the photos to make only the ID card that belongs to each citizen, so that the people of the Ming Dynasty can travel freely within the territory of the Ming Dynasty! "
"Because only the people of Ming Dynasty have ID cards, and people from other countries don't have ID cards!"
It turns out that this is Zhu Kezang's thinking.
It is used for anti-counterfeiting first, and it will be further developed in the future.
"Your Majesty, you actually thought of this, but it's very troublesome. Moreover, my Ming Dynasty had a strict household registration system, so there is no need to promote ID cards!" Huang Luzhuang suggested.
The household registration system of the Ming Dynasty is very strict, and it was very strict during the period of Zhu Yuanzhang. However, no matter how strict this household registration system is, it also has great drawbacks.
In the 14th year of Hongwu, Zhu Yuanzhang ordered the whole country to start compiling household registration yellow books.
The yellow book system is more detailed and thorough than the household allowance system.
Not only the birthplace, name, age, Dingkou, field house, assets and other information of each household are registered.
But these are only stored in the government, and there are very few things in the hands of ordinary people to prove their identity.
Luyin is a proof, but it is easy to fake.
If someone who knows Daming very well forged a guide and appeared in the capital, how can he make inquiries?
The other party is absolutely sure that they can deal with your inquiries.
But with an ID card, it is different. It is very light and can be issued to individuals. As long as there is no ID card, all of them must be strictly interrogated, so that no one will be spared.
"Then tell me, how many people in this capital are from Henan, how many are from Shandong, and how many are from Beizhili?"
"This...Your Majesty, this can also be ascertained according to the yellow book of the Ministry of Households!"
This can be a question to Huang Luzhuang, how can he understand these things!
"What I want is not just for you to find out. What I want is for you to quickly find one of them. What I want is for the Jinyi Guards and the Criminal Department to be able to easily know all the information about this person when they patrol. And it’s not fake!”
This……
Hearing what Zhu Kezang said, Huang Lvzhuang was at a loss for words, because according to Zhu Kezang's request, they could not do it with any system in Ming Dynasty, but if the ID card was popularized, it could be done.
"Your Majesty, I will handle this matter as quickly as possible!"
Huang Luzhuang couldn't wait to build the camera and improve it.
Of course, it will be difficult, and I will explore this unknown field of chemistry purely by myself and my students.
And Huang Luzhuang was very lucky, just right, now Daming has materials that can improve the Daguerreotype camera.
That is nitrocellulose.
After half a year of exploration, they finally improved the Daguerre camera through nitrocellulose.
That is to dissolve nitrocellulose in the collodion of ether and alcohol, then dissolve potassium iodide in the collodion, and immediately apply it on a clean glass, put it into a camera for exposure, and obtain a glass negative film after developing and fixing.
Collodion must be used immediately after preparation, and it will no longer be sensitive to light after it dries, so this photography method is called "wet plate method".
Although the operation of the wet plate method is cumbersome, the cost is low, only one-twelfth of the daguerreotype method. The exposure is faster than the daguerreotype method, and the image definition is also high. The glass negative can print a large number of photos.
In the Qianqing Palace, Zhu Kezang is holding a piece of cardboard to take a closer look.
The material of this piece of paper is to add some other materials to the high-quality mulberry paper, so that the texture is both tough and hard. As long as it is not soaked in water, it can be used for a long time.
There is also a photo of Zhu Kezang on it!
This is Zhu Kezang's ID card!
This is Daming's first generation identity certificate, and it will replace the guide slip that has been used for hundreds of years and become the latest identity certificate of Ming Dynasty.
On the top of the first line on the front of this piece of paper, the words "Daming Citizen ID Card" are printed, and then below is the introduction of the holder's personal identity information, such as name, gender, place of origin, age, physical characteristics, etc. Its specifications and style are basically the same as the ID cards of later generations.
On the back of the ID card is a passage like this: Anyone who holds this card is a citizen of Ming Dynasty. He should abide by the laws and regulations of Ming Dynasty, consciously maintain the social stability of Ming Dynasty, and must not participate in anything that endangers the foundation of social stability of Ming Dynasty.
