The telegraph changed the way the world communicated!
In just a few seconds, a telegraph machine could know information from the other side of the world.
This method of communication directly changed the transmission of letters. In the past, messages between armies were first communicated using beacon smoke.
Use beacon towers, fast horses, homing pigeons, and any other way to increase speed.
But the transmission efficiency requires more than a day to cover a distance of 800 miles.
By the time they got the information, the battlefield had already changed.
It's all too slow.
No matter how fast information is transmitted, it is difficult to be effective in the face of an ever-changing battlefield.
However, the invention of the telegraph machine allowed this information to be conveyed to Long Yan quickly. Even on the battlefields of Europe and even the Americas, it was even easier for Liu Zheng, who was far away from Long Yan, to know the information on both sides.
In his previous life, Liu Zheng knew that the advent of the telegraph changed many ways in the society of that era.
The telegraph can bring people much closer.
"Take me to see it quickly!"
Liu Zheng dropped everything he was doing and hurried back to the Liangzhou laboratory with Bert.
It’s been a blast all the way.
Starting from Beijing, it actually took Liu Zheng less than a day to arrive at the Liangzhou Laboratory.
It was the first invention since the dynamo that changed the world.
He rushed into the Liangzhou laboratory and looked at a strange thing connected to the generator.
Liu Zheng and Burt walked in, and Burt was about to call out the people who were addicted to the experiment.
He stopped Bert and whispered: "Don't disturb them."
Liu Zheng looked over and saw that there were too many parts that he had never seen before.
At this time, the generator driven by the steam engine was running, and the direct current sent out entered this strange 'transmitter'.
When those scientists, who looked like they had come out of a refugee camp with disheveled hair, entered a series of long and short signals.
This signal is transmitted through another wire to another strange piece of equipment connected to it, making sounds of varying lengths.
Everyone was silent for a second.
Someone said in disbelief: "It worked..."
"Success?"
"Success!"
Everyone cheered, and the data that had been calculated day and night after countless efforts were thrown into the sky.
These beeps of different lengths confirmed to them that the time and energy they spent were worth it!
This is all for the best!
"It's great, it's great!"
"Morse, you invented something that changes time!"
"We are proud of you!"
Morse's nose became sour: "No, it was us who changed the world. It was you who came up with the method of using static electricity to absorb paper. It was you who created the prototype of the telegraph!"
"I just made a few changes based on him."
Although this invention was not his idea, it was a change made by his hands.
He was originally a painter and knew nothing about electricity.
I only embarked on this path because I was very interested in electricity.
He himself never imagined that he could invent something that could change the world.
Snapped! Snapped! Snapped!
Applause rang out. At this time, everyone turned their heads and looked over, only to notice someone coming.
"Master Liu!"
Liu Zheng cast an approving look at the scientist named Morse: "You are very good. You were able to invent the telegraph."
Morse put his left hand on his chest, leaned forward slightly and saluted, saying, "Thanks to Mr. Liu's guidance, otherwise, I wouldn't have been able to make something like this."
"But it's not perfect yet. It can only transmit signals within the power grid. There is no way to get rid of the constraints of these wires."
Liu Zheng smiled and said: "It is already very good that you can achieve this step. Longyan's power grid has begun to be laid, and your invention may become our first popular electrical appliance."
"You deserve to be proud."
"But you also need to invent a little thing so that the signal transmitted by this telegraph machine will not be known to other people."
"Won't be known to another machine besides the one he passed it on to."
Moss replied: "Sir, regarding this problem, we have already come up with a plan to deal with it."
"Although the two telegraph machines are connected, they use the same frequency band, so they can receive each other's signals."
"If you adjust the frequency band, you will no longer be able to receive a signal between the two machines."
After hearing such a simple design, Liu Zheng understood it immediately.
This is what he wants to say, using the mediation frequency band to provide such functions between telegraph machines.
Liu Zheng nodded and asked: "How far can the current telegraph transmit signals?"
Morse replied: "About a thousand meters or so."
Liu Zheng frowned slightly. This distance was still a little short. Unfortunately, capacitors and batteries have not been developed yet. Otherwise, the principle of the telegraph could be used to further develop radio.
When the wireless telegraph is invented, their communications will really not be constrained.
Liu Zheng thought for a moment and said, "Morse, you did a good job, but don't be proud."
"You can achieve more, just keep improving him."
"I believe you can improve the capabilities of the telegraph machine again."
After receiving the affirmation, Morse said with great enthusiasm: "Don't worry, sir, I will definitely perfect the telegraph machine."
Liu Zheng thought for a while and decided to tell him the principles of radio now, hoping that he could develop a radio transmitter as soon as possible.
With this kind of radio transmitter, Long Yan's army can get accurate information even if they are in any corner of the world.
Especially on the current battlefield, the war in America and Europe is not over yet.
If the historical trajectory here overlaps with the history I knew in my previous life.
Britain will be the biggest beneficiary of this war.
Soon, Britain would go to war with a new nation in America.
They Long Yan need to establish a foothold in America before this war comes.
Liu Zheng wrote down the principles of radio on the paper and handed it to Morse.
"This is a gift for you to successfully research the telegraph machine, and it is also a test. I hope you can use this knowledge to develop better things."
Morse nodded heavily and accepted Liu Zheng's gift.
Looking at the content recorded on the paper, I just feel endless knowledge pouring into me.
He softly read what was written on it: "Radio, electricity is a kind of energy. It can not only propagate in wire beams, but also propagate in invisible air..."
This sentence alone broke Morse's cognition.
This was knowledge beyond his cognition. How could electricity spread in the air?
He continued to look down and saw that the radio principles explained by Liu Zheng came from a subject that although they had already set foot in, they had not yet thoroughly studied it.
The principle of electromagnetism!
