Siheyuan: Craftsmen of a Great Country

Since she had no idea about the Internet, even though Jiang Chen became Sister Jiang, she was still confused.

Only now they can be sure that Jiang Chen was not just having an impulsive fantasy, but really wanted to do this and already had a plan.

Cao Jun saw that everyone looked dazed, and knew that a supporting role was needed at this time, so he said:

"Dean Jiang, even computers with relatively simple functions are this big now. If they are to carry so many functions, how big must they be?"

Jiang Chen smiled and said, "This is just a basic computer, it's too big."

"And what we need to do is to miniaturize the computer. How small should it be? At least one person can easily twist it away."

"It can even be small enough to fit in the palm of our hands, and children can easily carry it around."

Everyone turned around to look at the huge computer, and then looked at their own hands.

The brain is about to shut down again.

"Is this possible?" someone asked.

Jiang Chen said: "It's still what I said just now, everything is possible."

"The key to computer miniaturization is the miniaturization of processors. And the key to processor miniaturization is integrated circuits."

"You may not know what an integrated circuit is because it only appeared last year. Simply put, it is a large number of electronic components concentrated on a chip."

"The higher the level of integration, the smaller the electronic components, and the smaller our integrated circuits will be."

"Originally, I didn't have these ideas at first. But with the emergence of integrated circuits and the successful development of Qiming Machine Tools, I felt that we had a chance to achieve computer miniaturization."

Cao Jun said: "So, the core work of our computer and component group is the research of integrated circuits?"

Jiang Chen said: "The processor is the core component of the computer, but this team not only needs to study integrated circuits, but also storage devices, input/output devices, displays, etc."

“And the materials chemistry group studies related substances that can carry various functions for use by other groups.”

With the cooperation of Cao Jun, the two of them asked and answered questions and basically explained the main tasks of the brother group.

At this time, Wu Ming, the leader of the information team, said, "So, Dean Jiang, what is the main task of our team?"

Jiang Chen said: "Research on the information transmission method, find the best way to transmit information, and research the information transmission carrier."

Wu Mingdao: "You mean, traditional telecommunications methods don't work?"

Jiang Chen nodded: "No, the loss is too great, the power is too low, and the transmission is too slow. It is basically impossible to achieve real-time."

Wu Ming asked, "What does Dean Jiang think?"

Jiang Chen answered concisely: "Light!"

Wu Ming glanced at the bright sunshine outside the window: "Light?"

Jiang Chen asked: "Do you know about total reflection of light?"

Everyone shook their heads.

People who are not professional researchers of light generally don't pay much attention to things at this level.

Jiang Chen nodded: "Okay, let's do an experiment on the spot."

"Cao Jun, go find a pike and drill a small hole on the side of the boat. Block the hole first, then fill it with water."

"Xiaoxue, go find a flashlight."

The two agreed and hurried to prepare.

Wu Ming said: "President Jiang, why are you looking for water? Do we need to include water in our materials? Isn't that a bit dangerous?"

When water and electricity meet, danger can easily occur.

Jiang Chen said: "No, I just want to show you the total reflection of light, or the capture of light."

Everyone was stunned.

"capture?"

Can light be captured?

Another argument that goes against common sense, and everyone is full of doubts.

Jiang Chen did not continue to explain further, and everyone would understand after the experiment.

Soon, Cao Jun brought back a bucket full of water as requested, with a stopper plugged into the hole at the bottom of the side.

Jiang Chen asked him to put the bucket of water on a table, with another bucket underneath to collect water.

Luo Xue also handed the flashlight in her hand to Jiang Chen.

Jiang Chen said: "Pull up all the curtains."

Someone immediately drew all the curtains.

The curtains here are double-layered. When both layers are drawn together, the room becomes pitch dark and you can't see your hand in front of you.

Jiang Chen turned on the flashlight and pointed it at the top of the bucket: "Next, it's time to witness a miracle."

"Cao Jun, unplug it."

Cao Jun, who was standing by the bucket of water, reached out and pulled out the stopper.

The shining water flowed out of the small hole in the bucket.

A shining column of water was very dazzling in the dark conference room.

But outside the water column, it was still pitch black.

That is, no light comes out of the water column.

The water bends, and the light bends with it. The light is actually captured by the water.

After a while, the water in the bucket decreased to below the plug, no water flowed out, and the light column disappeared.

Jiang Chen said: "Open the curtains."

Then he explained: "The density of media such as water is greater than that of the surrounding air, that is, when light is directed from water to air, the refracted light disappears due to the larger angle of incidence, and all the light is reflected back into the water."

"So, the light is trapped by the water."

Wu Mingdao: "But water is too unstable and easily loses its properties. We can't use water as a medium to transmit information."

Jiang Chen nodded; "Of course we can't use water. We just need to find a substance that is as transparent as water and can also achieve the same effect of capturing light."

Wu Ming and Cao Jun glanced at the window and asked in unison, "Glass?"

Jiang Chen nodded: "Well, glass is indeed a very good solution."

Do you think that he went to great lengths to revitalize the two glass factories and have them conduct scientific research and improve the technological content of their products just for the construction industry?

of course not.

Optical fiber and display screens are the more important purposes.

Wu Ming nodded: "So, the main task of our group at this stage is to create a material that can capture light and enable it to transmit light waves losslessly and efficiently?"

Jiang Chen nodded: "You can say that, but you should pay attention. As of now, glass is indeed the best solution."

"However, the solution must be verified through continuous experiments. If it is ultimately proven that glass is not feasible, then other materials must be found to replace it."

"Your task is to create this medium. As for the specific material, I don't care."

"The Materials Chemistry Group can provide you with relevant support, but their focus is not here. Instead, they are assisting the Component Group in conducting research on integrated circuits."

"You can also find those two glass factories to cooperate with your work."

Once it was determined that information could be transmitted using electromagnetic waves such as light, the rest of the things became much simpler.

The problem of how to convert information into light and then convert light into information has been solved, and the transmission problem has been solved.

Now binary has been proven to be the most suitable for computers because of its simplicity, reliability, efficiency and easy extensibility. Therefore, the programming team must develop system programs on this basis.

The core is the computer operating system.

Other storage, control, computing, software and other systems are also their responsibilities.

The Computer and Components Group is responsible for the production of various computer components so that they can carry out relevant functions.

In each of these groups, Jiang Chen assigned workers who have participated in computer production, and their experience will play a big role.

Of course, the overall progress still depends on him.
