Daming Town Haiwang

Chapter 2151, Phone

A group of students are constantly discussing the possibility of making flying machines. At the same time, the number of this team is increasing. Many students from various majors and fields want to join this team to study flying machines.

"It's full of energy!"

Liu Jin on the side watched all this with a smile on his face.

Compared with the students who will only fall in love and play games in later generations, these students seem to be more energetic and innovative.

Thinking about the education of future generations, it has actually gone astray. Most of the time, they only study theory and lack of practice. There are many masters who are good at the rounds of exams, but when it comes to practical ability, they are basically useless.

There is also the policy of strict entry and wide exit in colleges and universities, which also leads to the waste of youth in the years of college, a waste of time and a waste of the most dynamic and innovative period.

It is precisely because of this lesson that Liu Jin pays great attention to practical ability in the colleges he founded. Many things actually need to be done by himself, experimented, designed, and thought about before he can truly implement them. to master.

"Sir, sir!"

Seeing that everyone was discussing intensely, Feng Shuang also looked at Liu Jin and said with a smile: "I wonder if Mr. is interested in joining our team to study this flying machine?"

"I'll forget it, I think you can definitely develop this kind of flying machine."

When Liu Jin heard this, he immediately laughed. These students are really interesting. They even invited him to join this team. He didn't have time to study these things, not to mention that he actually knew very little.

"That's such a pity!"

"Sir, if you can come up with such an idea, you must be a person of great knowledge. If you join us, sir, we will definitely be able to research it very quickly."

Upon hearing this, Feng Shuang said with a little regret.

"Haha, this world is the world of your young people. You young people are innovative, imaginative, and dare to fight. You will definitely be able to break into the sky in the future."

"I very much look forward to your early research on a machine that can fly in the sky."

"If you can really research it, you can come to me at that time. I am willing to invest in you, build factories for you, improve and mass-produce flying machines."

Liu Jin smiled and affirmed them.

"Really?"

When Feng Shuang, Feng Dan, Chen Tianyu, Li Chaoying, Zheng Mingxuan and others heard this, they couldn't help but widen their eyes slightly.

This is meeting the God of Wealth!

Take a closer look at Liu Jin, the attire in this suit is not ordinary people, just the jade pendant hanging around his waist, it is the top imperial green jadeite.

There are also the servants and guards following this identity, and the Mercedes-Benz parked on the road not far away, all of which tell everyone that the gentleman in front of him is obviously a rich man and a big man.

"Of course it's true."

"If you are successful in your research, you can come to my house to find me at any time. My name is Liu Jin. You can also ask the principal of the school to contact me."

"Boy, I am very optimistic about your flying machine."

Liu Jin smiled and announced his name.

"Liu Jin?"

Hearing Liu Jin's words, everyone was even more taken aback for a moment, and then all of them widened their eyes.

"You are Mr. Liu!"

Feng Shuang hurriedly saluted Liu Jin respectfully again, and only then did the others react.

This is when I met Liu Jin and Liu Gong, one of the founders of the Royal Institute of Technology of Ming Dynasty, the chief assistant of the current cabinet.

All of a sudden, they stood up straight and saluted Liu Jin in unison.

"Ok!"

Liu Jin nodded back with a smile, and then said: "You are all very good, very energetic, and very innovative. I hope you will study hard, study hard, and do your part for the prosperity of our Daming."

"I also look forward to your researching this flying machine as soon as possible. When you research it, I will come back and take a look."

After speaking, Liu Jin also left.

Many students also watched Liu Jin leave, and when Liu Jin left, everyone became excited.

"It's Liu Gong, one of the founders of our academy!"

"It turned out to be Mr. Liu!"

"Mr. Liu is indeed the same as in the rumors, handsome and handsome, with an extraordinary bearing!"

"Liu Gong actually said that when our flying machine is built, he will come to see it, and he is willing to invest in me so that we can continuously improve this machine and build a factory to produce these machines."

Feng Shuang, Feng Dande and the others were very excited. How could they not be excited to see Liu Jin, the chief assistant of the cabinet, and get Liu Jin's affirmation.

On the other side, Liu Jin got into the car and went straight to the office of the principal of the college.

It was only when I arrived at the office building of the principal of the college that I learned that the principal was no longer here, but went to the Institute of Electromagnetics to watch a new invention, so Liu Jin got in the car and went to the Institute of Electromagnetics.

Here is a classroom in the Institute of Electromagnetics. At this moment, the entire classroom is full of people, including the principal of the school, the dean of the college, teachers related to electromagnetics, and many students.

"This thing can really talk over a long distance?"

Xia Peiliang, the principal of Daming Royal Institute of Technology, looked at the strange machine in front of him and asked.

The machine in front of me has a long wire extending all the way to a classroom at the other end of the college. The two classrooms are separated by several miles. It is obviously unrealistic to shout with your voice.

At the same time, this device also has a small speaker device, which looks a bit like the setting on a phonograph to play sound, and then there is a metal cup used to look like a cup.

To be honest, Xia Nongyu couldn't believe that it was possible to have a conversation over a long distance with such a simple device.

"Yeah, can this thing really talk over a long distance?"

Wei Nanping, a professor at the School of Electromagnetics, also felt a little unbelievable.

"of course can."

"The remoteness of the telephone machine is very simple, and it is similar to the remoteness of the gramophone."

"A few years ago, I had been researching the use of electromagnetics to simulate the human voice, but there was no major breakthrough until the appearance of the phonograph, which gave me a lot of inspiration."

"Using the sound made by the spiral electromagnetic coil between power-on and power-off can simulate the human voice. This is the most basic principle of the phonograph."

"Since the phonograph can broadcast and record human voices, why can't we develop a voice that can communicate in real time?"

Kuang Xiong, who is also a professor of the School of Electromagnetics, said very firmly.

The phone in front of him was invented by him and his students after a long period of practice and research.

"The principle of the phonograph is indeed the same. It uses the grooves on the record to form the on and off of the current, and then affects the coil to produce sound."

When Wei Nanping heard this, he thought about it and expressed his affirmation.

As soon as the phonograph came out, there was a wave of research on the phonograph among the teachers and students in the college.

After a little research, everyone found that the principle of this phonograph is actually very simple. It is nothing more than a phonograph invented by using the sound that the copper coil makes when the current is switched on and off.

It is said that the person who invented this phonograph was an engineer from the South African colony. This invention alone sold tens of thousands of taels of silver. These tens of thousands of taels of silver are a very large fortune, enough to live a prosperous life without worrying about food and clothing. .

This also makes everyone very envious. Many people regret that they are also studying electromagnetism, and they have also discovered the phenomenon that the coil will make a sound when the current is switched on and off, but they did not study it carefully, otherwise they would be able to invent the phonograph. up.

"Then try it quickly, try it quickly."

When Xia Peiliang heard this, he hurriedly gave instructions to Kuang Xiong.

"Ok!"

Kuang Xiong nodded, and then ordered someone to turn on the electricity, then picked up the cup-like device and said, "I am Kuang Xiong, I am Kuang Xiong, please answer if you receive it, please answer if you receive it!"

"received!"

"Teacher Kuang, Teacher Kuang, I am Luo Xian, I am Luo Xian."

Just a moment later, a voice rang out from the loudspeaker.

Everyone around them widened their eyes slightly when they heard this voice. This thing can really talk over a long distance.

"Luo Xian, Luo Xian, I am the principal Xia Peiliang, can you really hear the voice?"

Xia Peiyu took the cup-like device and asked.

"Principal, hello!"

"I can hear your voice from here."

Soon, Luo Xian's voice came from the speaker again.

"Very well, what time is it over there?"

Xia Peiyu still couldn't believe it, rolled up his sleeves, looked at his watch and asked.

"Principal, my time here is half past eleven in the morning!"

Soon the voice came again, Xia Peiliang looked at his watch, his eyes widened slightly, the time was right.

"It's unbelievable. With such a simple device, real-time long-distance calls can be realized. This is much better than telegrams. Telegrams still need to be accepted and deciphered. This phone can talk directly. "

Xia Peiyu finally believed it, and couldn't help but sigh to the people around him.

"It's really amazing!"

"Theoretically, as long as there is a long enough wire, we can talk in real time even if we are on the other side of the earth."

Kuang Xiong nodded solemnly and said.

"This phone is so useful. I believe it will become as popular as the gramophone soon. At that time, it will be possible to make calls at any time, no matter where it is. It will be so convenient!"

"Yes, this call is definitely very valuable, Mr. Kuang, you are going to get rich!"
