When Liu Weichao heard this, he immediately clapped his hands and said, "Okay, it's time to let Jin Yiwei make contributions! To be honest, I prefer Jin Yiwei, but Jin Yiwei has relatively few achievements that have been passed down to future generations. The most praiseworthy one is
At that time, the news that the Japanese pirates were going to invade Korea was sent back to the Ming Dynasty!"
After a pause, he explained: "For future generations, the Jinyiwei's majestic style of punishing corrupt officials is very popular, and it is considered to be for the people; while spying on the enemy's military situation is for the country, for the country
What you do for the people will definitely be passed down to future generations!"
Emperor Chongzhen said "Oh" after hearing this. The most important duty of the Jin Yiwei is to be the minions of the royal family!
But Liu Weichao liked it, and he didn't want to be disappointed, so he didn't say anything.
When Liu Weichao's excitement subsided a little, Emperor Chongzhen asked him a question: "But Dongjiang Town and the Japanese country are too far away. Take a look and see if there is any technological power like this."
It's like a mobile phone, can it allow me to communicate in real time?"
In fact, he had mentioned this request before. However, Liu Weichao said at the time that based on his technological foundation, it was not yet possible to achieve it.
Now, when he encountered this problem again, Emperor Chongzhen raised it again.
This time, let alone Liu Weichao, he said to him: "Generally speaking, communication can be divided into two types: wired and wireless. However, there is still a lack of scientific and technological foundation. To implement it in a country as big as the Ming Dynasty, there are some problems
Difficult. But there is a method. Although there are many restrictions, it can be supplemented to some extent to strengthen long-distance communication."
When Emperor Chongzhen heard this, he was immediately overjoyed and asked quickly: "What is the method? Please tell me quickly!"
"Actually, the principle is very simple!" After hearing this, Liu Weichao introduced it to Emperor Chongzhen, "It's similar to the beacon communication, but instead of using beacons, there are some bars on the flagpole. Different arrangements can express different meanings. This way
, in a very distant place, if you regularly use a telescope to watch the arrangement and combination on the flagpole, you can know what it means to convey. In this way, it is passed on level by level. Theoretically, it can be transmitted very far in one day
place!”
Others may not understand some of the modern words in his words, but Emperor Chongzhen has been chatting with him for several years, so he has no problem.
Therefore, when he heard this, he immediately remembered the coding that Liu Weichao had told him before. This permutation and combination should mean that.
Emperor Chongzhen thought about the scene Liu Weichao mentioned in his mind, and felt that it could indeed be transmitted far away, and he couldn't help but show a happy expression on his face.
However, after Liu Weichao saw his expression, he immediately attacked him and said: "However, this method is subject to many restrictions. In weather such as rain, snow, heavy fog, etc. that affects the vision, this method cannot be used. Also, this method cannot be used.
The location of this method is also very important. It must be far enough away to clearly see the arrangement on the flagpole, and it also requires an agreement on when to initiate such communication..."
In one breath, he mentioned many shortcomings.
However, Emperor Chongzhen was not disappointed, and still had a happy expression. When Liu Weichao finished speaking, he smiled and said: "This method is good! I have a telescope! As for the manpower, I can use the manpower of the ready-made post station.
Site selection will take some time and needs to be verified by the people below."
Having said this, he raised his voice and immediately said, "I have decided to do this."
No matter what you do, it costs money. However, today's Emperor Chongzhen is confident, and he doesn't feel bad about spending this money.
Seeing that he had made up his mind, Liu Weichao said to him: "Okay, I'll give you the information on this method later, go and use it!"
The communication method he mentioned was originally called the Charp Signal Tower in its original history. It was a signal tower proposed by Claude Charp during the French Revolution, that is, in the 18th century.
This kind of signal tower is a device with two huge cantilevers installed at both ends of the beam. They are controlled by cables. The cantilevers can form seven angles, with a difference of 45 degrees between adjacent ones. The beam itself can also rotate, but the sand
The beam is generally limited to 2 angles and each cantilever has 7 angles, so this kind of signal tower can transmit a total of 98 possibilities at a time.
At its peak, this kind of Charp signal tower was spread all over France, covering more than 700 kilometers from Toulon in eastern France to Paris, and it might only take ten to twenty minutes.
Of course, the shortcomings are also obvious, and both Liu Weichao and Emperor Chongzhen mentioned them in their speeches.
After all, the Ming Dynasty was much larger than France, and it was very likely that the sun would rise in the east and rain in the west, which would cause this kind of communication interruption.
However, before the invention of the telegraph, this kind of Shapu signal tower was still necessary. No, Emperor Chongzhen wanted to build one because this communication method was fast enough.
After Emperor Chongzhen hung up the video communication, he thought for a moment and did not immediately send an order to the commander of the Jinyi Guards. Instead, he picked up his mobile phone and spoke to Liu Weichao, asking him to compile a piece of information about the Japanese situation during this period and give it to him.
.
It didn't take long for him to receive information sent to him by Liu Weichao. There were information from the Japanese country and the Shapu Signal Tower.
As for the Shapu Signal Tower, Liu Weichao also had suggestions. The one originally suitable for French was not suitable for the Ming Dynasty. Simply use digital encoding.
His proposal to Emperor Chongzhen was to summarize the Chinese characters of the Ming Dynasty and record them on a large piece of paper without duplication. According to later generations' data, a thousand commonly used Chinese characters can cover 90% of the writing.
In other words, if you can't write a thousand Chinese characters on one piece of paper, you can just write on two pieces of paper. However, Liu Weichao estimated that as long as Emperor Chongzhen was willing, he could make a large piece of paper and write small enough words on it.
It is no problem to write a thousand Chinese characters using just a piece of paper.
Then, it’s simple. As long as the numbers combine the abscissa and ordinate, you can locate a Chinese character. Basically, it can be done. The two-digit abscissa and the two-digit ordinate can express the meaning of a Chinese character.
The ancient literati paid attention to being concise and concise, speaking briefly, similar to sending a telegram, so that they could quickly convey a message.
There is no need to copy this Shapu signal tower, because it does not require so many combinations. It can be as simple as possible. It only needs ten ways of expression. It can even be marked with colors, such as red on the front and black on the back.
, red represents the abscissa, then turn it over and use black to represent the ordinate, which can also reduce errors in information transmission.
Liu Weichao put forward this idea and told Emperor Chongzhen to test it first and replace it with a better method if there was a better one.
After reading the information, Emperor Chongzhen liked it very much, so he drove over to Concubine Tian.
"Your Majesty, what's the good news?" When Concubine Tian saw Emperor Chongzhen's smiling face, she knew there must be something good and asked immediately.
Emperor Chongzhen took out his mobile phone and asked Concubine Tian's confidants to start copying out the information inside. He watched from the side, and then said to Concubine Tian: "Chen Yuanyuan who came out from your place did a very good job!
"
For the time being, he didn't want to talk to anyone about the Japanese affairs.
Concubine Tian had already heard about Chen Yuanyuan. At this time, she couldn't hear anything new, so she took advantage of Emperor Chongzhen's happiness and said: "The special scientific examination on Physics is coming soon. Your Majesty is interested in the field of Physics in an eclectic way."
Talented people, I thought, as long as they have talents in the field of physical studies, they can participate, right?"
Emperor Chongzhen was lying on the couch, tapping the armrest with his hand, and said with a smile: "Of course!"
In fact, this matter has already caused quite a stir before.
If you think about it, three generations, or even four generations, live in the same household. Many of them took the preliminary exam of studying physics together, and even passed it, and then went to the capital to take the scientific exam together. This kind of thing is not as common as ordinary imperial examinations.
There may be!
Regarding this situation, some people feel that it is unreliable and there is something wrong with it, and some have reacted to it.
However, when Emperor Chongzhen was discussing matters in the Wenhua Hall, he made it clear that he was thirsty for talents in the field of gewu scholars. He did not ask for anything else, but only for talents. Ten thousand years is too long, and he only seizes the day and night.
Because the officials below judged based on this decree and allowed this rare thing to happen.
When Emperor Chongzhen heard this, he affirmed it and even felt a little proud: The master of Zhongxing, the only emperor through the ages, was to be able to do what others could not do, and to create something that had never been done before.
In the atmosphere of the late Ming Dynasty, there was the kind of openness, pursuit of freedom, and going one's own way. Emperor Chongzhen was living in this great era, and he was affected to some extent. Without the pressure of subjugation, when he was high-spirited, he also had this kind of unconventional meaning.
At this time, after Concubine Tian heard Emperor Chongzhen's affirmative answer, she immediately asked: "Can the maids and chamberlains around me also take part in the special scientific examination on geophysics?"
When she said this, Emperor Chongzhen answered too quickly and immediately added: "Anyway, His Majesty wants talents who study physics, regardless of their origin, right?"
"..." Emperor Chongzhen was speechless when he heard this.
But if you think about it carefully, I said at the beginning that anyone can participate regardless of whether they have fame or not. This really means that they don’t care about their background.
Emperor Chongzhen thought about his original intention, then nodded and said: "Yes, you can participate!"
Hearing his words, the palace maids and chambermaids who were copying beside him became very excited. It was obvious that they had been doing two things at once and were also eavesdropping.
After hearing this, Concubine Tian smiled, rolled her eyes, showing a hint of playfulness, and then asked Emperor Chongzhen: "In that case, can the princes and princesses also participate?"
