After Yang Xiaotao got up in the morning, he was pressed on the chair by the old Taoist, and then an iron pusher rang out on it, with a bunch of hair falling down in the middle.
"Old Master, is your skill good?"
Yang Xiaotao watched the big buns of hair fall down and was a little suspicious of the old Taoist craftsmanship.
The old Taoist smiled, "Don't worry, I used to be in the army, so I worked as a part-time barber."
"Don't worry."
"It would be strange if I don't worry."
Yang Xiaotao muttered, and the boys from Dragon Boat Festival next to him ran over and shouted, very happy.
"Go and go, wash your hands and eat."
Yang Xiaotao sent a few children, and then was interrupted by the old Taoist, "Don't move around, otherwise it will be ugly if it is twisted."
"Don't blame me then."
Yang Xiaotao dared not move around, it was related to his appearance, and his hairstyle was very important!
After finishing his hair, Yang Xiaotao hurriedly went to the house to wash his hair and then looked in the mirror.
OK, this little flat head has nothing to do with appearance.
As it turns out, as long as the dish is hard, there is not much difference between a plate or a bowl!
In the yard, the old Taoist voice came, and the next one continued.
After breakfast, everyone left the yard and walked towards the factory.
Yang Xiaotao took his men to the Ninth Courtyard.
After a while, I sat down in the office, I received a call from Han Sanfeng, saying that I had made the small calculator, Wang Kun and the others.
Upon hearing this news, Yang Xiaotao immediately put down his work and went to the research institute.
Be careful with the Calculator Research Office, Yang Xiaotao was immediately welcomed into it after he arrived.
"Yang's!"
"Teacher Yang!"
There were many people saying hello, Yang Xiaotao nodded to everyone, and then followed Han Sanfeng to Wang Kun and Liu Yongqiang quickly.
The two of them looked excited, then moved aside, revealing a wooden box on the table, which was about twenty centimeters long and ten centimeters tall.
Yang Xiaotao walked up to him, and everyone surrounded him.
"Yangbu, this is the small calculator we made."
Liu Yongqiang spoke and introduced, and opened the wooden box.
Yang Xiaotao stepped forward and looked around and found that it looked a bit like the later calculator, but it looked much bigger.
In addition, there are not so many buttons, only horizontal and vertical rows. If you look carefully, you will see that from left to right are 0, 1, 2, 3.
Below are numbers, then addition, subtraction, multiplication and division, and finally, an equal sign and a box.
Yang Xiaotao guessed that this box should be reset to zero.
In other words, this calculator can only be used to calculate addition, subtraction, multiplication and division, and there are no other ones for the time being.
Perhaps, this is the limitation of technology.
Seeing Yang Xiaotao looking at him, Wang Kun immediately explained, "Yang Bo, we made a simple calculator based on digital logic circuits!"
"The entire calculator is mainly composed of three main parts, namely the core calculator and controller, display screen, and power supply part!"
"We used a large amount of high-purity silicon as transistors in the arithmetic and controllers to meet our needs according to the design requirements!"
“This is also the hardest part of the manufacturing process.”
"But we did it."
Speaking of this, everyone's faces became more proud.
"Through operations, we can process addition, subtraction sums and calculations of multiplication and division below five digits!"
"This is a display screen, made by Tianjin Electrical and Mechanical Plant..."
"This is the power supply. We are using AC power now. When we pass by, we will change it to DC power in the future. Just use the battery..."
Wang Kun explained the situation carefully, Yang Xiaotao listened seriously, and everyone around him showed a novel expression.
Among them, he is the worker involved in the development of calculators. He has no specific impression of what calculators do, let alone others!
However, Yang Xiaotao was prepared for this. After looking at it for a while, he asked, "How to do it?"
Liu Yongqiang immediately took out the calculator and placed it in front of Yang Xiaotao, "Yang, these are the buttons!"
"We are just a preliminary design, and it will be improved in the future!"
While speaking, Wang Kun handed over the machine and Liu Yongqiang turned on the power.
The display screen in front of everyone suddenly shone, and a row of black numbers appeared on it.
Starting from nine, I kept retreating, and finally came to zero, and there was another flash of flash. In the end, there was only one zero on the display screen on the far right.
"Yang Bi, this is the normal working state, which means it can be operated!"
Wang Kun said, Yang Xiaotao hurried forward and asked in the button, "Press it directly?"
"Can!"
Wang Kun nodded, then pointed to the top button, "This is zero, one, two, and three..."
"This is the addition, subtraction, multiplication and division symbol, followed by the equal sign, and then the clear button..."
In fact, Yang Xiaotao can understand without Wang Kun's explanation.
After Wang Kun finished explaining, Yang Xiaotao looked at everyone and smiled, "How are you all arithmetic?"
The people around were stunned and didn't understand what it meant.
Finally, Lou Xiao'e, who followed him, said, "Yang Bu, we are good at arithmetic!"
"Anyway, they are all people who have gone to school."
Others around him nodded after hearing this.
Yang Xiaotao nodded, "Okay, then let's take the test!"
"Listen."
“What is one plus one equal to?”
"two!"
Many people shouted out with a smile. At the same time, Yang Xiaotao also pressed the equal number on the calculator, and saw a number ‘2’ appear on the screen. Wang Kun and Liu Yongqiang were relieved when they saw it.
"Okay, then what is two plus two?"
"Four!"
Everyone shouted again, and 4 appeared on the screen.
“What about four plus four?”
"eight!"
"What about eighty percent?"
"sixteen!"
Someone just shouted it out and thought it was wrong.
Someone laughed, and then the person who reacted immediately shut up. This was smooth, but he didn't hear it clearly.
Yang's team doesn't play according to the routine.
At this time, Yang Xiaotao looked at the number on the screen, 64.
Everyone looked at the screen, very happy.
"It seems that everyone's arithmetic is very good."
"Of course, the premise is to hear it clearly."
Yang Xiaotao joked, then cleared his throat again, "Listen, what is sixty-four times sixty-four?"
This chapter is not over, please click on the next page to continue reading! After Yang Xiaotao asked, some people around him were calculating in their hearts, some were gesticking with their fingers, and some were directly holding pens to calculate.
But Yang Xiaotao had already stopped and saw the words ‘4096’ appear on the screen.
Wang Kun and Liu Yongqiang looked at each other and were both excited.
They have tried this kind of test, and Yang Xiaotao's experiment this time was more shocking to everyone.
“Four thousand ninety-six.”
Someone shouted out, and more people nodded as they listened.
However, seeing the display screen in front of Yang Xiaotao, the smiles on everyone's faces disappeared.
Because the numbers above are the same as their calculation results.
But, they took seven or eight seconds, while Yang's army only took three seconds.
"It's right."
Yang Xiaotao asked softly, and everyone nodded.
Many people looked at the calculator.
Yang Xiaotao’s operation just now was very simple, especially Lou Xiao'e and others who often deal with numbers. They were already thinking that if there were such a machine, the work in the future would be much easier.
"Continue, listen."
"What does 4096 multiply by 4096 equal?"
After Yang Xiaotao asked, everyone's faces changed.
Many people scratch their heads because the multiplication of these four-digit numbers has exceeded their computing power.
Some people saw Yang Xiaotao’s intentions and thought to see if this machine could calculate it.
However, some people took out paper and pen and calculated carefully.
Yang Xiaotao still pressed the button slowly. Every time he pressed it, a number would appear on the screen.
Until the equal sign is pressed, a string of numbers appears.
Everyone looked at the numbers on the display screen and their eyes were dazzled.
So long.
At the same time, I was a little curious. Is it so accurate to calculate it so quickly?
At this time, someone finally calculated the calculation results, and then took the paper and started to recite, ‘16777216!’
Every time I read a number, everyone will look at the display screen.
Until the last reading was finished, everyone was silent for a moment, and then they clapped their hands.
Han Sanfeng suddenly realized that the biggest advantage of this calculator is its speed!
The more complex the arithmetic, the faster it can solve it.
If the results are more accurate, then this calculator can greatly improve the efficiency of certain work.
As for accuracy?
Han Sanfeng is also a computer researcher. Of course, he knows that as long as the computer is well set, it will be better than humans.
Thinking of this, Han Sanfeng felt a little regretful.
I regret not turning on the integrated circuit research of computers as soon as possible.
‘It’s okay, it’s not too late!’
After making up my mind, the focus of the research center will be shifted after today.
No matter how well the transistor computer is researched, it is just chasing the lower runway.
If you want to catch up with your opponent, you have to think of some external moves.
On the other side, Yang Xiaotao nodded, and then recognized the person who finally calculated it. He was the first group of students who entered the classroom at Yangjiazhuang Primary School.
Yang stick.
This child impressed him deeply back then.
Because I am young, I can't keep up with the pace when I go to school.
When Yang Xiaotao and Ran Qiuye were entering junior high school, when they first entered primary school, they were hesitant to let him participate.
Later, I participated, just pretending to be like making soy sauce and seeing the world.
But I didn't expect that this kid was very successful and actually passed the exam.
Although he was the last one and just got stuck on the passing line, he also went to junior high school.
Later, Yang Xiaotao did not pay special attention to the development of these students, but because of Ran Qiuye's duration.
"Let's go on."
Yang Jian was stunned, and immediately said, "Okay Teacher Yang."
Everyone didn't care about Yang Jian's name, and they all knew about Yangjiazhuang.
"What is it that 16777216 divided by 32?"
After hearing this, Yang Park quickly took the notebook and pencil to the side and started calculating.
Without Yang Xiaotao talking about this time, Han Sanfeng came to the calculator, started typing the content, and then pressed the equal number.
524288!
Han Sanfeng read out the numbers, and then everyone looked at the young man lying on the table not far away.
At this moment, Yang Pao sweated on his forehead, especially when he heard the sound from behind and the attention he felt, which made him feel like he was being peeped.
At the same time, he didn't want to make a fool of himself in front of Teacher Yang, because that was to embarrass Teacher Yang.
The operation of division is more difficult than multiplication, because multiplication and subtraction are also required.
So, after more than two minutes, Yang Jian walked up to him with a notebook, and shouted loudly about the calculated results.
After a moment, Yang Xiaotao applauded gently.
Then, the applause was warm.
“It’s pretty good.”
Yang Xiaotao smiled at Yang Jian, then took out the pen in his pocket, "This is a reward for you."
Yang Jian was stunned, and then carefully took it with the urging of the people around him.
"Reward you is not only because you calculate correctly, but also because you are willing to calculate."
"In this world, many things seem difficult, but if you really wait to do it, you will find that they are not as difficult as you imagine."
Although Yang Xiaotao said this to Yang Jian, everyone present remembered it in their hearts.
Especially Han Sanfeng, he felt that Yang Xiaotao was waking him up and made up his mind to form a team as soon as possible.
The second is Wang Kun and Liu Yongqiang, who are the people who feel the most.
When Yang Xiaotao found them, they explained the situation, and they still felt that it was a bit "unbelievable".
But later, I persisted until now.
Now, isn’t it a success?
"Actually, the most difficult thing is to convince yourself to take the first step!"
