The ups and downs of life in the Siheyuan

At 12 o'clock in the evening, in the entire courtyard, only the east wing of the front yard was lit.

In fact, he can work in the basement without others seeing the light.

But he was unwilling to take advantage of this, so he paid 2 yuan per month in exchange for this benefit.

Since there are many graphics, he also pursues effects.

First complete the graphic simulation in your mind, and then carefully copy it on white paper.

He revised a few more pictures along the way, so he didn't finish the task until midnight.

I read it from the beginning and am very satisfied with this handwritten PPT.

The reason why he worked so hard to express it graphically was because he wanted to overwhelm the opponent in terms of expression.

Give the evaluator the most intuitive impression.

Because the human brain is most sensitive to graphics, it is easy to understand and remember.

Text is different. The brain needs a process to convert words into images.

The expressive ability of words is different, and the images conveyed are also incomplete.

Everyone’s experience is different. Understand that filters will construct images that are familiar to him and weaken unfamiliar images.

In this way, the content expressed in words will cause ambiguity.

Therefore, in terms of performance, he firmly believed that he had won a city.

When I went to work the next day, Representative Tong came over early.

"Li Yuan, how are you preparing the materials?"

"Here you go." Li Yuan walked to the bag and handed him 10 pages of paper from inside.

The other party couldn't wait to take it.

The home page is quite satisfactory, with the main title: Research on Counter-Battery Radar Computing Unit.

Subtitle: 10 seconds of ultimate experience.

"Hey!" He didn't understand the meaning of the subtitle.

When you open the first page, there are 4 words divided into 12 lines.

He raised his head and glanced at Li Yuan, who had his eyes closed in deep thought, with a strange expression.

Turning to the second page, there was only one picture, a picture that he could understand at a glance.

It was his first time to receive PPT baptism, and he was immediately attracted by this picture.

The input and output are clear at a glance, and several formulas in the comments immediately improve the technical content of the graphics.

At the bottom is a comparison picture, a matchbox with a cuboid with centipede legs on it, and the word "chip" written on it.

The cuboid occupies less than half the area of ​​a matchbox.

A circle is drawn on the periphery of the functional structure diagram above, and the chip is at the end.

"Hiss! You mean all these functions are concentrated in this so-called chip?"

"clever!"

He read page after page, and he learned something new on each page.

Although he doesn't know its actual principle, he knows what this thing does.

Take transistors, for example. Li Yuan used levers to illustrate his amplification principle; he used electric gates to illustrate his switching principle.

When he saw the positioning calculation formula, he actually understood it.

The very vivid ballistic trajectory, the three points in the air where the artillery shell flew, and a few simple connections allowed him to understand how to judge the artillery position.

As for those formulas, what does it have to do with him? He only cares about those dotted lines, because the dotted lines point to the artillery positions.

On the last page, there are only three lines:

The first industrial revolution, mankind entered the steam age;

During the second industrial revolution, mankind entered the electrical age;

With the three industrial revolutions, chips will lead mankind into the era of science and technology.

After reading it again, Representative Tong gave Li Yuan a thumbs up.

"Lao Li, it has to be you! Tell me, what do you want me to do?"

"Come here," Li Yuan said mysteriously.

Then Li Yuan made a small request to him.

"Don't worry, it will be ready for you on Monday."

After speaking, he took the PPT and left the laboratory with a big smile.

Monday, December 1962, 12, in the small auditorium of a research institute in Kyoto.

Many leaders came today, and there were even more officers among them.

The leaders rarely sat in the audience, and there was a table, a stool, and a microphone on the podium.

The host walked to the podium and introduced the leaders and guests present.

Then a middle-aged man walked up to the podium with a manuscript.

After sitting down, blow the microphone habitually.

"Dear leaders and distinguished guests, on behalf of the Institute of Computing Technology, I would like to introduce to you the design plan of the transistor computer..."

He first explained the disadvantages of tube computers, such as short lifespan, high power consumption, and large footprint.

Then we spent half an hour explaining the principles and advantages of transistors.

Except for some guests who listened with great interest, most of the leaders frowned, and some even dozed off.

After laying out the technology, he began to explain the functional components of the computer and mentioned how to use transistors to perfectly replace vacuum tubes.

As for how to locate artillery positions, he simply said that he only needed to write a program.

Finally, use the table in front of you to describe the size of a transistor computer.

The more than 2-hour report meeting actually received warm applause from everyone.

Some of the guests were the most excited, as they seemed to have found a direction for their efforts.

The middle-aged man bowed and walked confidently off the stage.

At this time, the host came to the podium again and said, "Now, I would like to ask Director Li from 621 Laboratory to introduce the chip solution to everyone."

At this time, two soldiers were carrying a small blackboard onto the podium and placed it in the center of the podium near the audience seat.

There are several 1-inch large papers held in clips on the blackboard.

This is the secret why Li Yuan asked Representative Tong to find someone to copy the drawings onto larger paper.

I saw a very elegant young man walking up to the podium.

A general in the first row sat up straight, his eyes filled with anticipation.

Seeing a young man who looked like a college student walking up to the podium, there was a burst of noise from the audience.

Many people were notified to attend the transistor computer report meeting of the Institute of Computing Technology today.

Everyone didn't know there was an extra scene.

Li Yuan held the microphone in his hand and faced the audience.

“Dear leaders and seniors, good morning everyone, I am very honored to participate in this exchange meeting.

I will spend half an hour introducing to you how to use chips to realize the calculation function of anti-artillery radar."

Li Yuan pointed out the theme directly and closely followed the needs of the military.

Just the first sentence attracted the attention of all officers and relevant research institute personnel, including of course the first platoon leaders.

The first page is fine, but when it comes to the second page, the functional structure diagram and chip concept appear.

There were waves of discussion below:

"I'm shocked. He's so talkative and weak in his work. He actually uses Western concepts to fool us old guys!"

"It's just that such a small thing can realize positioning calculations. It's simply a fantasy!"

"If he can achieve one-tenth of what he said, I can eat the 104 computer."

. . . . . .

At this time, the general just stood up and turned to face the person behind him.

"If you don't want to hear it, get out!"

Then he glanced around majestically, and immediately, the auditorium returned to silence.

The old general looked at Li Yuan on the podium and immediately put on a smiling face and said, "Xiao Li, continue."

After 25 minutes, Li Yuan finished explaining all the PPTs.

The venue also fell into a dead silence, and many people didn't know how to comment.

Call him nonsense, everyone can understand the principle and there is nothing wrong with it.

Unlike the technical staff, the soldiers all began to talk enthusiastically.

"With such a small thing, you can stick it anywhere, and you don't have to worry about installation space at all."

“The key is that it consumes almost no power!”

. . . . . .

At this time, the middle-aged man representing the computing institute stood up and asked: "There is nothing wrong with the principle you mentioned. It is also feasible to concentrate the circuits on a wafer.

But, I want to ask, how do you concentrate so many devices on such a small wafer? "
