Scholars in the courtyard

In February 2, Long looked up.

When Yang Xiaotao got up in the morning, he was pressed on the chair by Lao Dao, and then a iron pushing Zidong Gatong sounded on it, and a group of hair fell down in the middle.

"Lao Dao, you can't do this craft."

Yang Xiaotao watched the hair of the big group falling down, and was skeptical of Lao Dao's craftsmanship.

Lao Dao laughed, "Don't worry, in the army, I was part -time workers."

"Don't worry."

"I don't worry, it's strange."

Yang Xiaotao murmured in his mouth, and a few boys next to the Dragon Boat Festival ran over and drank, very happy.

"Go and go, wash your hands and eat."

Yang Xiaotao sent a few children, and then was interrupted by Lao Dao.

"Don't blame me at that time."

Yang Xiaotao didn't dare to move. It is related to the face value, but the hairstyle is very important!

After the hair was finished, Yang Xiaotao quickly went to wash his hair in the room, and then looked in the mirror.

Well, this little flat head has nothing to do with the face value.

It turns out that as long as the dishes are hard, the plate is not much different!

In the courtyard, the sound of the old way came from the next.

After having breakfast, everyone went out of the yard to the factory.

Yang Xiaotao took someone to the Ninth Court.

After sitting in the office and sitting down for a while, he received a call from Han Sanfeng, saying that the small calculator, Wang Kun, did it.

Hearing the news, Yang Xiaotao immediately put down his hand to work to the research institute.

Be careful of the research department of the calculator, Yang Xiaotao was immediately greeted in it.

"Yang Min!"

"Teacher Yang!"

There were a lot of people who greeted them. Yang Xiaotao nodded at the crowd, and then followed Han Sanfeng to Wang Kun Liu Yongqiang.

The two looked excited, and then let the open position exposed a wooden box on the table. The length and width were almost twenty centimeters.

Yang Xiaotao walked around, and everyone was around.

"Yang Job, this is the small calculator we made."

Liu Yongqiang introduced it and opened the wooden box by the way.

Yang Xiaotao stepped forward, and then looked around, and found that it was a bit like the calculator of later generations, but it looked a lot bigger.

In addition, there are not so many keys, only four rows of horizontal and vertical, carefully look at 0, 1, 2, 3 from left to right.

The following is the number, and then the addition, subtraction and multiplication, and the final number and a box.

Yang Xiaotao speculated that this box should be zero.

In other words, this calculator can only be used to calculate, subtract, and multiply, and there is no other for the time being.

Perhaps this is the limitation of technology.

Seeing Yang Xiaotao beside him, Wang Kun immediately explained, "Yang Min, we according to the digital logic circuit, the simple calculator made by the system!"

"The entire calculator is mainly composed of three main parts, namely the core operator and controller, the display screen, and the power supply part!"

"Among them, the operator and controller, we used a lot of high -purity silicon as a crystal tube, according to the design requirements to meet our needs!"

"This is also the most difficult part of the manufacturing process."

"But we still do it."

Speaking of which, everyone was proud of.

"Through the operation, it can deal with the calculation of the multiplication and division of the multiplication and division below the nine digits of the addition, subtraction, and the calculation of below the nine digits!"

"This is the display screen, which was made by the Jinmen Machinery Plant ..."

"This is a power supply. We are now using AC electricity. If we pass by in the future, we will change to DC power, just use the battery ..."

Wang Kun explained the situation carefully. Yang Xiaotao listened seriously, and the people around him showed a novel expression.

Among his can, the workers participating in the calculator research and development have no specific impression of the calculator, let alone other people!

However, Yang Xiaotao was prepared for this. After watching a while, he asked, "How to operate?"

Liu Yongqiang immediately took out the calculator, and then put it in front of Yang Xiaotao, "Yang Min, these are the keys!"

"We are just a preliminary design, and we will be perfect in the future!"

During the talk, Wang Kun handed the machine and Liu Yongqiang connected the power supply.

The display screen in front of everyone suddenly brightened, and then a row of black numbers appeared on it.

Starting from nine, I continued to retreat, and finally came to zero, and there was a flash of flickering. The final display only had one zero on the right.

"Yang Job, this is normal working state, which means that it can be operated!"

Wang Kun said, Yang Xiaotao quickly stepped forward, and then asked the key, "Press directly?"

"Can!"

Wang Kun nodded, and then pointed at the top button, "This is zero, one, two or three ..."

"This is an addition, subtraction and multiplication symbol, the later is equal to the number, and then the zero button ..."

In fact, no need to explain Wang Kun, Yang Xiaotao can also understand.

After Wang Kun's explanation, Yang Xiaotao looked at the people laughed, "What do you do?"

The people around me did not understand what it meant.

In the end, Lou Xiao'e, who followed, said, "Yang Min, our arithmetic is okay!"

"How to say are all people who have studied."

Other people around nodded.

Yang Xiaotao nodded, "Okay, then test you!"

"Listen."

"One plus one is equal to?"

"two!"

Many people shouted with a smile. At the same time, Yang Xiaotao also pressed the equivalent number on the calculator. I saw a number '2' on the screen. Wang Kun and Liu Yongqiang were relieved.

"Okay, what is the two plus two?"

"Four!"

Everyone shouted again, and 4 appeared on the screen.

"Four plus and four?"

"eight!"

"What about 80 %?"

"sixteen!"

When someone shouted, it felt wrong.

Someone laughed, and then the people who reacted immediately closed their mouths.

Yang Bubble does not follow the routine.

At this time, Yang Xiaotao glanced at the number on the screen, 64.

Everyone also looked at the screen and was very happy.

"It seems that everyone's arithmetic is very good."

"Of course, the premise is to hear clearly."

Yang Xiaotao was fun, and then cleared his throat again, "Listen, how much is sixty -four?"

After Yang Xiaotao asked, some people around him were counting in his heart, some fingers were scratched, and some people counted directly with a pen.

But Yang Xiaotao had stopped at this time, and saw the four words ‘4096’ on the screen.

Wang Kun and Liu Yongqiang looked at each other and were excited.

In this test, they have tried. Yang Xiaotao's experiment was more "shocked" for everyone.

"Four thousand ninety -six."

Someone shouted, and more people nodded.

There is no mistake, one post, one, one, one, one, one, one 619, a book, one, one, a look!

However, seeing the display in front of Yang Xiaotao, the smile on the face disappeared.

Because the numbers above are the same as the result they calculated.

However, they used seven or eight seconds, and the Yang Bob took only three seconds.

"Correct."

Yang Xiaotao asked gently, everyone nodded.

Many people look at the calculator.

Yang Xiaotao's operation just now is very simple, especially Lou Xiao'e and others who often deal with numbers. They have already calculated that if there is such a machine, then the work in the future can be reduced a lot.

"Continue, listen."

"How much is 4096 by 4096?"

After Yang Xiaotao asked, everyone's face changed.

Many people scratch their heads, because the four -digit multiplication has exceeded their computing power.

Others see Yang Xiaotao's intention, and they even thought about whether this machine can be counted.

However, some people still took out the paper and pen to take it seriously.

And Yang Xiaotao still held on the keys without any disappointment. Each press, a number appeared on the screen.

Until equal to the number press, a string of numbers appear.

Everyone looked at the numbers on the display, dazzling.

So long.

At the same time, I was a little curious. Even if it came out so soon, is it so accurate?

At this time, one person finally calculated the calculation result, and then I started thinking with the paper, ‘16777216! ‘

Every time you read a number, everyone will look at the display.

Until the last one after reading, everyone was silent for a moment, and then slammed the palm.

Han Sanfeng suddenly realized that the biggest advantage of this calculator is fast!

The more complicated the arithmetic, the faster you can solve it.

If the result is accurate, then this calculator can greatly improve the efficiency of certain work.

As for accurate?

Han Sanfeng also studied computer. Of course, as long as the computer is settled, it will be better than people's execution.

Thinking of this, Han Sanfeng regretted it.

I regret not turning on the integrated circuit research of the computer for the first time.

‘Okay, not too late! ‘

In my heart, I made up their minds. After today, the focus of the research center will be transferred.

No matter how good the transistor computer is studying, it is only chased on the lower runway.

If you want to catch up with your opponent, you have to make an external trick.

On the other side, Yang Xiaotao nodded, and then recognized the last person to be the first student in Yangjiazhuang Elementary School.

Popular stick.

The child was impressed by the child.

Because I am young, I can't keep up with the rhythm when I go to school.

When the elementary school was promoted to junior high school, Yang Xiaotao and Ran Qiube hesitated to let him participate.

Later, I followed the participation, so I followed the soy sauce to see the world.

But I didn't want to, this boy was also a fight, and he was admitted.

Although it is the last one, I just stuck on the line, but I also went to junior high school.

Later, the development of these students did not pay special attention, but Ran Qiuye was contacted.

"Let's continue."

Yang stick stunned, and then said immediately, "Good teacher Yang."

Everyone didn't care about the name of Yang stick, and they all knew about Yangjiazhuang.

"16777216 except 32, what is it?"

Yang stick heard the book with a pencil and started to calculate.

This time, Yang Xiaotao said that Han Sanfeng came to the calculator and started to enter the content, and then pressed the equal number.

524288!

Han Sanfeng read out, and then everyone's eyes looked at the young people lying on the table not far away.

At this moment, Yang's forehead was sweating, especially when he heard the sound from behind, and the attention he felt, all made him feel a peeping feeling.

At the same time, he didn't want to be ugly in front of Teacher Yang, because it was shameful for Teacher Yang.

Division is more difficult than multiplication, because it also requires multiplication and subtraction.

So, more than two minutes later, Yang Gun came up with a notebook and shouted the result loudly.

After a while, Yang Xiaotao clapped gently.

Then, the applause was enthusiastic.

"Not bad."

Yang Xiaotao smiled at Yang Gun, then took out the pen from his pocket, "This is a reward for you."

Yang Gun was stunned, and then carefully took it under the urging of the people around him.

"Reward you, not only because you calculated correctly, but also because you are willing to calculate."

"In this world, many things look difficult, but when you really wait to do them, you will find that they are not as difficult as you imagined."

Although Yang Xiaotao said this to Yang Gun, everyone present remembered it in their hearts.

Especially Han Sanfeng, who felt that this was Yang Xiaotao's wake-up call, and made up his mind to form a team as soon as possible.

The second was Wang Kun and Liu Yongqiang, who were the most touched.

When Yang Xiaotao found them and explained the situation, they still found it a bit ‘unbelievable’.

But later, they persisted step by step until now.

Now, isn’t it a success?

“In fact, the most difficult thing is to convince yourself to take the first step!”
