"Bring it here!"
Chongzhen stretched out his right hand as he spoke, and Wang Chengen immediately took out a small box from the carriage and presented it to him.
Under the curious eyes of everyone, Chongzhen opened the box, took out a silver cylinder about one foot long and two centimeters thick, and handed it to Bo Jue.
Bo Jue took the silver cylinder and touched it carefully, only to discover that there were six grooves about one millimeter deep on the silver cylinder, spiraling from the bottom to the head.
"Your Majesty, I forgive you for being stupid, I don't understand!"
"Aren't you thinking about how to improve the hit rate of cannonballs? This may be able to help you.
After the iron mold casting technology matures, you can try making a barrel in this way and you will know. The number, width, depth, twist, etc. of the negative wires need to be explored by yourself.
For specific details, ask the craftsman who oversees the bank and he will tell you! "
call……
As soon as Chongzhen finished speaking, everyone in the Firearms Research Institute breathed a little faster. They understood the importance of accurately hitting the target and the difficulty of research.
"Zijue, show it to the teacher!"
"Junior brother, show me senior brother, show me half a stick of incense, and I'll give you two days to start. I won't go the other way if you tell me something!"
"Bo Jue, let me have a look and study it for a day, and I will give you the original copy of my lifelong research experience!"
"Bo Jue, show me. If you want to study anything in the future, just come to me. I'm in charge of the household department. You can give me whatever you want!"
"Bo Jue, I'm in charge of the Ministry of Industry and I know all about the Ming Dynasty's materials. Show it to me. If you need anything for research in the future, you can come to me!"
…
Everyone stared at the silver cylinder in Bo Jue's hand, full of curiosity, and made offers one after another. They wanted to grab it and study it carefully.
Seeing the hungry looks in everyone's eyes, Bo Jue instantly stuffed the silver cylinder into his clothes, making everyone dumbfounded.
Watching this scene, Chongzhen felt very funny.
With this rifling model, can I definitely make a barrel with rifling? Chongzhen could not answer this question.
The rifling of later generations was drawn by a lathe. He didn't know exactly how it was drawn, and the rifling was very shallow. It was unknown whether it could be made directly with an iron mold, but it still provided an idea.
"Bo Jue, what I have given you is just a direction. I don't know whether it can work or not. The next step depends on your research. I am waiting for your good news!"
"I will do my best to research it as soon as possible!"
"If you have other ideas, you can try them. Don't go all the way!"
"I understand!"
After Bo Jue finished responding, Chongzhen looked at the ministers again: "I still need to discuss some things with Xu Aiqing and the cabinet. If you are interested in this place, just take a look!"
"Xu Aiqing, Bi Aiqing, Sun Aiqing, let's go to the meeting hall!"
Seeing that the emperor was walking out of the valley, the six cabinet ministers could only follow him. They could not enter the firearms research institute on weekdays, let alone stay here.
They are just interested in this place, but they don't want to die. The fewer secrets they know, the longer they can live.
Two-quarters of an hour later, in the meeting hall of the Firearms Research Institute, Chongzhen sat in the first seat, with four people sitting on the left, Yuan Keli, and three people sitting on the right, Xu Guangqi.
Chongzhen took a sip of tea and looked at Xu Guangqi: "Xu Aiqing, tell me about Matteo Ricci's situation!"
Although he didn't know what the emperor wanted to do, Xu Guangqi still pondered for a moment: "Your Majesty, please wait a moment while Rong Chen goes to get some things!"
"Go!"
After half a stick of incense, Xu Guangqi entered the meeting hall with a scroll. Amid everyone's curiosity, he hung the scroll on the wooden board on the side. What appeared in front of everyone was a map, which was a map of mountains and seas.
The so-called map of mountains and seas is a map of the world in Chongzhen's eyes. After all, there is still one hanging in Dongnuan Pavilion.
Xu Guangqi pointed to the map: "Your Majesty, Matteo Ricci set out from Italy on September 13th, the sixth year of Wanli. He took the coastal road around the Cape of Good Hope and entered the Indian Ocean, crossed the Strait of Malacca, and then arrived in Goa, India. He arrived at Haojing in the tenth year of Wanli.
In September of the 11th year of Wanli, he arrived at Shangqing Bay in Zhaoqing Prefecture. In the 13th year of Wanli, a Catholic church was built in Shangqing Bay. The prefect Wang Pan also presented two plaques: Xianhua Temple and Xilai Pure Land. "
"That's not right!"
Sun Chengzong interrupted Xu Guangqi's words and frowned: "Dean Xu, I remember that in the eleventh year of Wanli, the Ming Dynasty was still closed to the outside world and no foreigners were allowed to enter, let alone preach.
How did Matteo Ricci enter the Ming Dynasty? Also built a Catholic church in Ming Dynasty? "
"This this……"
Xu Guangqi looked a little embarrassed. Seeing that the emperor also looked at him inquiringly, he could only bite the bullet and said: "Your Majesty, what Mr. Sun Ge said is true.
Yichen's understanding was the result of Jesuit priests bribing officials of the governor's office to smooth things over. It is said that he gave a mechanical clock to Huang Yingjia, the commander-in-chief of Guangzhou. Huang Yingjia liked it very much, and then discussed with the governor of Guangdong and Guangxi to grant the privilege. Did he report it to the court? I’m not sure. "
"I see!"
Chongzhen nodded. Fifty or sixty years have passed since the incident. The parties involved are probably already rotten to pieces, and there is nothing they can do to pursue it.
Then again, if it weren't for Matteo Ricci, Xu Guangqi and others probably wouldn't have been able to come into contact with Western learning, or they would have come into contact with Western learning a few years later. In that case, the Firearms Research Institute might not be as big as it is today.
"Xu Aiqing, keep talking!"
Seeing that the emperor was not prepared to pursue the case, Xu Guangqi breathed a sigh of relief and continued: "During the six years in Zhaoqing, Matteo Ricci translated the "Portuguese-Chinese Dictionary", drew the Chinese world map "The Map of Mountains and Seas",
He developed the first mechanical self-ringing clock and hanging watch in the Ming Dynasty, and also co-translated the first six volumes of Euclid's "Elements of Geometry" with Chen. "
Listening to Xu Guangqi's words, Chongzhen sighed very much.
There are already clocks and clocks, and there are also several palaces, but the people of the Ming Dynasty seem not to be able to accept this foreign object. The time in the palace still tells the time according to the heavenly stems and the earthly branches.
There are also places to manufacture clocks in Guangzhou, Jiangnan and other places, but because of the difficulty in making them and the high price, they are only available among wealthy businessmen, and most of them are just for decoration.
The main reason is still inconsistent. When you are at home, someone says it is three o'clock in the afternoon, and when you go outside, they say it is You hour. Your brain still needs to do the math for a while, which is very inconvenient.
Clocks, sundials, and water clocks each have their own advantages and disadvantages in their timing methods. Clocks run by springs and need to be turned on at regular intervals, otherwise they will not be accurate. Sundials, on the other hand, require the sun and cannot be used at night.
It’s not that Chongzhen worshiped foreigners, but in his opinion, clocks were far more convenient than sundials, especially when marching, fighting, etc.
If the sky is cloudy, an error of one or two quarters of an hour may change the course of a war.
After sighing with emotion, Chongzhen continued: "Xu Aiqing, please continue to talk about your knowledge of Italy!"
