After thinking of this, Cao Ang felt a little helpless, this was his own shortcoming, his own deficiency.
It cannot be said that Cao Ang's hands-on ability is poor, but because Cao Ang is not very clear about the situation, and he is not so strong in scientific research in this area, so Cao Ang feels that this situation is very special hard to control.
Compared with the steam engine, it is dozens of times more difficult to manufacture a phone. Not only that, the various research and development, as well as the various thresholds, are very difficult.
It is simply impossible to make this phone in a short time.
Therefore, after Cao Ang thought of such a situation, he dismissed the idea.
Telephones are impossible now, so can there be something similar in nature to the telephone, and it is not too difficult to make under the current conditions?
After thinking of this point, Cao Ang's heart suddenly became bright.
There are so many things used for communication, so why chase after a mobile phone?
If it’s rare that it can’t be done, why not just make a simple one, for example, the telegraph machine is a good choice!
Chapter 449 Publishing Research on the Telegraph
After thinking of the telegraph, Cao Ang was also excited.
The problem I want to solve now is the inconvenience of information transmission, and now I only need to solve the inconvenience of conveying confidence. Will this matter be completely resolved soon?
Things like the telegraph are also very good choices, although there is still a lot of gap between them and the telephone.
However, under the current circumstances, it is very simple to develop a telegraph.
Cao Ang was quite clear about the telegraph in his heart.
Morse code (also translated as Morse code, morsecode) is a kind of on-off signal code, which expresses different English letters, numbers and punctuation marks through different arrangement sequences.
It was invented in 1837 by the controversial inventor, American Samuel Morse or Alfred Weir.
Morse code was an early form of digital communication, but unlike modern binary codes that only use zeros and ones, its codes include five: dots, dashes, pauses between dots and dashes, each Short pauses between characters, medium pauses between each word, and long pauses between sentences.
This is the famous Morse code. This Morse code can be said to have created very efficient codes, and then spread and interpret these codes, so as to send out the information you want to spread.
Under such circumstances, a very efficient and very safe way of transmitting information has been created directly!
The transmission of this information is mainly through the pause and long transmission of the current to transmit information.
It can be said that the invention of the telegraph has a trans-epochal significance and directly opened the prelude to the telecommunication era, and it also created the history of the first time human beings used electricity to transmit the information they wanted to transmit!
After Cao Ang thought of this, he couldn't be more urgent for the invention of the telegraph.
It is very necessary to try this telegraph now. After all, this electric power has been developed now, and according to the current technology, there are talents, and the ability to develop it is very powerful.
In addition, the telegraph is not difficult, and it is very possible to develop it according to the conditions we already have.
Of course, as for the telegraph, he, Cao Ang, does not intend to make such things universal and popular.
Because the Namors code alone is already very difficult, and it is as difficult as the sky to give these things to the common people.
Therefore, under such circumstances, Cao Ang planned to use the telegraph for military division and politics.
The significance of these two places can be said to be very huge. If such things are not done well, there is no need to talk about the timeliness of information, because it is impossible!
This is not only required by the current situation, Cao Wei's goal is to unify the whole of China, and above this China, the vast territory is obvious to all.
If the transmission of news is still so slow after the unification of all China, then what is the use of having such a vast and boundless land?
Some lawless people can easily take advantage of the timeliness of the news to do things that endanger unity and the public.
For such a situation, a telegraph is naturally needed.
As long as this telegraph machine can be developed, it must be beneficial to the rule of the imperial court and can closely connect various places.
The transmission of news can be completed directly in an instant. Such a situation is like a tiger with wings added to Cao Wei who is in charge of the court!
If the telegraph is developed, what will not be accepted by foreign military orders, the timeliness of news, delays, etc., will all disappear!
Such a situation can be said to be of great benefit to Cao Wei!
After Cao Ang thought of such a situation, he had already made up his mind that he would try anything about the telegraph.
Afterwards, Cao Ang handed over this task directly to Zhuge Liang, Sima Yi and others!
In addition, some people from Gewu College also participated in the research together with them.
Of course, since it is planned to start creating a telegraph, it is natural to explain the principle of the telegraph.
As for the principle of the telegraph, Cao Ang was very clear in his heart, so after deciding to hand over this matter to Zhuge Liang, Huang Yueying, and Sima Yi and others, he had already figured out what to do.
As for the principle of the telegraph, Cao Ang was very clear in his heart, so with the addition of these people who are good at research, such a situation is simply effortless!
It is not difficult to develop this telegraph, but the current time is definitely not allowed, and Cao Ang has no way of knowing the length of this time.
Regarding the development time of this telegraph, and when it will be developed, Zhuge Liang, Sima Yi and others will decide on this situation.
If Zhuge Liang, Sima Yi and others can go well, it won't take long for the telegraph to arrive!
After ordering such a situation, Cao Ang was relieved.
After the telegraph is developed, it will be able to clearly grasp the ever-changing battle situation on this battlefield, and even others can directly control the three armies without being in the front line!
In such a situation, after Cao Ang thought of such a picture in his heart, it can be said that he was very happy and excited.
……
At the same time, in Yizhou, the land of Bashu.
Yizhou at this time is very different from the past.
Under Guan Yu's suppression, Liu Zhang from Yizhou didn't dare to go out of the city at all, and even dared not take any action.
However, after a powerful army appeared in this land of Yizhou, Liu Zhang didn't know what was wrong, as if someone had a backer, he dared to operate in this land of Yizhou, and even dared to stand at a distance. Guan Yu was active not far away.
It is unbelievable that such a situation is true. Cao Wei's troops are still very clear about Liu Zhang's temperament, but now Liu Zhang is not afraid at all. It is really weird.
And the army that appeared on the ground in Yizhou was none other than the new leader of the Nawugo tribe, Meng Huo!
This Meng Huo looked very brave. He was two meters tall by himself, his eyes were as big as the eyes of a bull, and his muscles were all connected together. He looked very familiar.
Such a ferocious young man is still a giant, just by looking at it, he can exert a lot of pressure on the soul.
It was precisely because of this that Meng Huo would become the leader of the Wugo tribe, and even more so, he would recover a lot of the Nanman tribe.
