The principle of the so-called cable telegraph is actually very simple.

It converts the information into an electric current, which is then sent out through the wire and received by the terminal.

So, the transmitter is actually a keyed transmitter, while the receiver is an interpreter.

The principle of the artificial telegraph is that a person manipulates the electric keys, and the signals are formed through the 'points' and 'strokes' formed by opening and closing, and are transmitted through wires.

Morse also built on the foundation of his predecessors and designed a set of codes that encoded letters and numbers to facilitate transmission through circuits.

No need for complex circuits, just one line, and the problem can be solved!

To put it bluntly, it's just a piece of paper, just see if it's pierced or not.

But it is this kind of improvement that is much more reliable than that electrolytic signal, which is also the basis for the development of cable telegraphy.

What Sulu is going to come up with is this set of encoding and transcoding methods.

"As long as you have this, and build two more terminals, cable telegraph is completely possible! This will change the world......"

The speed of information dissemination is the difference between primitive society and modern society!

"I have to say that sometimes the feeling of making history is quite good!"

Looking at his design, Su Lu nodded: "Relying on this patent alone is enough for me to eat for a lifetime." If you set up your own telegraph company, it will be even more profitable! ”

The reason for coming up with the technology of cable telegraph. At this time, it is more to attract the attention of the above.

Only real talents can attract the attention of the top management of Greentree Fort and be absorbed into the interior!

This is not only an increase in status, but also helps many of Sulu's plans.

Therefore, he would rather suspend his transcendent cultivation than make it out in the Institute of Electricity.

In addition to this, he has another consideration in mind.

Although both the White Eagle Federation and the Greentree Fort Laboratory attach great importance to patents, he is a quiet man after all.

And the interests and future represented by cable telegraph are too great, and it is difficult to guarantee that there will not be a blind guy jumping out.

'If it's okay for you to cooperate, if it's really shameless enough to directly snatch the research results...... Hehe......'

Sulu sneered to himself.

He still has a big killer with wireless telegraphy in his hand!

The principle of wireless telegraphy is actually similar to that of wire, which is to convert information into electromagnetic waves, convert from low frequency to high frequency, and transmit and receive it through high-power antennas.

In effect, it is the exchange of the medium of propagation from the wires to the air.

If anyone wants to steal my work, let them do it...... After the other party builds a large number of buildings and lays a telegraph network, I will take out the wireless telegraph technology, and I will not kill these girls!! ’

In contrast to cable telegraphy, wireless telegraphy requires only a tall transmitter.

The cost was nothing compared to the cost of laying a telegraph line across the continent, or even across the ocean.

When the time comes, if they can't be killed, Sulu can add a gram to his surname!

……

Autumn on the East Coast of the Federation was not cold, and in the slight cool breeze, Sulu came to the laboratory.

"Where's the professor?"

He looked at Cecilia, who was working, and asked in a low voice.

"He's not in a good mood, don't bother him if you don't have anything special."

Cecilia replied.

This Sulu knows.

Professor William's large-scale communication experiments can be said to have been successful or unsuccessful.

The success lies in the fact that it is possible to transmit information using electric current, and it is very fast!

The failure lies in the electrolysis terminal, which is not only troublesome to operate, but also easy to make mistakes, and requires a large number of lines and extremely high costs.

Therefore, it is no wonder that the grant that Professor William hoped for was shot directly, and he was in a good mood.

"I have something important, I have written a paper that I want to publish internally!" Sulu replied.

In fact, in terms of the status of the Fort Greentree Laboratory, it is no different from publishing it internally than publishing it in the entire Federation.

"Hiss......"

Not surprisingly, Cecilia gasped: "You...... Thesis? ”

Although she knew that this newcomer was very powerful, she didn't expect the other party to be so powerful!

"I'll see."

She took the manuscript and glanced at it: "From direct current, the idea of electric current?" ”

"This is my chosen topic, with the consent of Professor William."

Sulu explained a few words on the side.

"Very nice and inspiring!"

Cecilia returned the manuscript to Sulu: "I think it's worth at least five points!" You can go to the tutor and he's in the office! ”

"Thank you!"

Feeling the envious and jealous gaze of Victor next to him, Sulu walked into the office unconsciously.

"Professor!"

William was behind his desk, designing something, his expression was single, and he couldn't tell whether he was happy or angry.

"This is my paper."

Sulu thought about it for a moment, but handed in the manuscript anyway.

"Hmm!"

William took it, glanced at it, and was a little surprised: "Compared with before, your derivation is more mature and rigorous...... Okay, I'll submit it for review, and you're good to go. ”

"Thank you!"

Sulu saluted and gently exited the door.

Wickdor looked at his back, and finally couldn't help but speak: "A newcomer wants to publish a paper?" Don't be scolded by your mentor......"

Andrew, who was wiping the table next to him, heard this, and his body immediately trembled.

"Alright, Victor, Sulu is indeed very capable and talented!"

Cecilia had to admit that this newcomer was very powerful, especially in the study of electricity, as if he had an innate talent.

While everyone else was struggling to navigate through the darkness, he held a torch and ran towards the goal.

He also ran very fast, like a wild horse with joy!

……

Late at night.

Institute of Electricity.

The Greentree Castle Laboratory is divided into the inner ring and the outer ring, which are under the jurisdiction of the Greentree Council.

The ninth Sislyden Walter looked like an ordinary old white man, with silver hair, but his eyes were bright, like two sparkling sapphires.

As one of the leaders of the laboratory, he is, of course, transcendent.

The old appearance could not stop his vigorous energy in the slightest.

One document after another was quickly reviewed and distributed by him, passing on orders one by one.

Suddenly, he pointed his finger: "Review committee? Are there any papers that they can't judge? ”

In his hands, there was an extra paper.

Green Tree Castle has a very strict review of internal papers.

And as a master in the field of electricity today, Sladen Walter also made a name for himself there.

Once he encounters an article that the other party can't review, he has the obligation to appear.

"Interesting."

Sladen Walter put on his reading glasses and looked at the beginning of the paper: "On direct current and some derivative ideas?" ”

When he looked at it, he had been watching it for a long time, and even the black tea on the table was cooled.

After a long time, Sladen Watt looked at the author: "Sulu Potley?" Interesting! ”

He immediately put down his pen and made a final reply: "The logic is clear, the thinking is concise, the review is passed, and it is recommended to reward 15 points." ”
