Iron Dynasty

Yes, let's see what this... telegraph!

In the laboratory, Niu Ben was rather impatient. In the ten years he had been in Qingzhou, he hadn't seen anything in his entire life.

He Dong grinned, and for those of them who were immersed in the lab, it was the greatest comfort to have someone appreciate the fruits of their labor.

So he said, Your Majesty, the two generals, please come with me.

After all, he led the three to a telegraph machine.

In front of the three of them is a transmitter. This transmitter is very simple. In fact, it is a power switch. However, unlike modern switches, this switch is a guillotine switch.

From this guillotine switch board, there are two wires leading to a ticker ten meters apart. The ticker consists of a coil wrapped in copper wire, an iron sheet on the coil, a paper roll and a pen. .

Two generals, this is a complete telegraph machine. Mainly press the switch, and the entire circuit will be connected. The copper wire coil is energized to generate a magnetic force to attract the iron piece down and make a beeping sound. This is a signal, and When the current is cut off, the iron piece will make a clicking sound when it returns to its original position, this is the second signal, and the combination of the length of the two signals can send information to the other party. He Dong explained to Niu Ben and Luo Quan.

As for Xiao Ming, there is no need to explain at all, because the whole set of codes he got was given to him by Xiao Ming, and now the codes are sent according to the small book he gave.

Niu Ben and Luo Quan were naturally confused, He Dong explained, and they looked at Xiao Ming helplessly.

At this time, Xiao Ming said: The two of you tell He Dong a word, don't let me know, and let He Dong send it to me with a telegraph later, and I will tell you what you just said.

Is there such a thing? Isn't this Shunfeng Er? Niu Ben looked incredulous, but turned his head and said a word to He Dong.

He Dong understood, he sat in front of the telegraph machine and used the code given by Xiao Ming to initiate a telegram. When He Dong sent the telegram, the iron piece moved the pen, and the pen began to draw on the white paper with the movement of the iron piece. A polyline.

After He Dong sent the telegram, Xiao Ming read: Luo Quan is not a thing!

Niu Ben was dumbfounded, and Luo Quan scolded angrily, You are nothing, old mad cow!

Hahaha... After being scolded by Luo Quan, Niu Ben was not angry, but became happy. He said, I didn't expect this thing to be so magical. It's just the emperor. It's a little too close.

It's not a problem. I asked Su Liangcai to lay down the telegraph wires by the way. As long as there are enough wires, I can go as far as I want. Using telegrams for a distance of thousands of miles is just a snap of my finger. As for those who have not built thermal power generation In the city of the factory, it is enough to temporarily use a small generator to maintain the telegraph.

The small generator mentioned by Xiao Ming is the small power generation equipment that Su Liangcai made when he first generated electricity in the laboratory, which is equivalent to a mini thermal power generation unit.

This thing is enough to provide the power supply of a government office, so that the wired telegraph will not be limited by the lack of thermal power plants.

Once the Great Yu Kingdom covers the whole country with telegrams, the imperial court's control over the Great Yu Kingdom will be more timely in the future.

A thousand miles of sound transmission is just a snap of a finger? Niu Ben and Luo Quan spit, in their opinion, it is really a supernatural ability.

Technology is really amazing. It's no wonder that the emperor wanted to promote technology at all costs, and he also let the underprivileged children of the Great Yu Kingdom go to school for free. If there are thousands of underprivileged children who understand technology, who else can shake the Great Yu Kingdom? Niu Ben's face turned red with excitement.

Luo Quan said: Yes, since they are all allowed to go to school for free, it must make them study hard, otherwise they will be beaten!

He Dong couldn't help rubbing his butt when he heard the words, and he said, Our students have not suffered less in the academy. These beginners, middle schools, and high schools will definitely only be more severe.

Xiao Ming gritted his teeth and grinned. He was really pressing on education. There is no such thing as quality education in this era. For him, instilling scientific and technological knowledge is the primary task.

Therefore, the primary school, middle school, high school, and university of Da Yu country are not set by the age of contemporary schools, but are based on the standards of Da Yu country. The time from beginner to high school graduation is only nine years, that is, three years of junior school. Three years in middle school and three years in high school.

Go to school at the age of six to complete graduation at the age of fifteen, and then after four years to complete university studies and enter all walks of life.

He thinks this time is quite short, but for the common people of the Great Yu Kingdom, this time is still very long. After all, ten years of hard work can lead to the number one official position, and the current education system all add up to thirteen years. year.

Education is the foundation of a strong country, and I will naturally not despise it. Xiao Ming said in a positive tone.

Now the Great Yu country has gone through a difficult ten years, from zero industrial base to between the first industrial revolution and the second industrial revolution.

Now he needs more elite talents to advance the technology of Dayu Kingdom, and those who have laid the foundation since childhood and entered the laboratory after thirteen years of education will definitely surpass Lin Wentao and other half-way monks in their comprehensive ability.

At that time, the technology of Dayu Kingdom can achieve rapid improvement. After all, with the efforts of the older generation, the industrial foundation has already been established.

After experiencing the wired telegraph machine, Xiao Ming looked at the three glass tubes that were being assembled in the experiment, which were exactly the electronic tubes needed for wireless telegraphy.

This kind of tube is simply a signal amplifier. Only by adding this thing can the radio transmit farther.

However, this kind of electronic tube is very large, because it is the most primitive electronic tube, and the material has not yet risen to the level of semiconductor, and only the most primitive rare earth grid material is used, but even so, this is also a problem for He Dong's team. , and this is what their lab is really working on.

After all, the wired telegraph is too simple, and it does not require more than 30 people to study it together.

There is no problem with the wired telegraph, and this one cannot be relaxed. Xiao Ming tapped the tube.

He Dong understood, he said; Now we are communicating with Lu Tong's School of Chemistry and hope they can help us with the materials. As long as the materials are in place, the tube will not be a problem. After all, welding will not be a problem after the power is turned on.

Well, I will ask him to cooperate with you. Xiao Ming patted He Dong on the shoulder.

Calculated in terms of time, technology in Europe is now at the time of the big explosion, and various inventions and creations will emerge one after another, because this is the result of the accumulation of European technology.

In addition, they have been guided by the scientific and technological achievements of the Great Yuguo, and they will avoid many detours and accelerate the technology.

Therefore, he can not relax in scientific research.
