In 1978, I was admitted to Harbin Institute of Technology

Chapter 50 You call this a calculator? Do you know what a computer is?
"Damn it, at least the production team's donkey is tired and needs to kick its butt!"

He Yang complained.

The donkey in the production team was good at kicking and had to be well taken care of.

But he was a graduate student and didn't dare to kick his ass like a tired donkey in front of his supervisor.

"what?"

Zhang Jingyan, who was concentrating on his work, looked at He Yang, who was broken, in confusion, "Brother, what animal did you just say?"

"No. I mean the animals in our production team, they have special people taking care of them with good grass and good feed every day, yet they are so damn lazy while working!"

He Yang looked at the beast in his eyes with displeasure.

"Brother, I feel like you are playing tricks on us."

Tang Long raised his head and looked at He Yang with a serious expression.

"What have you done to me, Yin Yang? Are you animals?"

Tang Long was about to retort, but Zhang Jingyan held him back, shook his head gently, and signaled him to stop.

They are from the experimental class.

Entering the chemistry laboratory was the opportunity that Xie Wei fought for.

He couldn't get into a conflict with the graduate students in the Chemistry Department just for the sake of a verbal argument. That would be bad for Xie Wei.

"..."

The other students from the Chemistry Department could only remain silent.

Facing the graduate students from the Department of Chemistry, I had no chance to participate in the project at this stage, but by luck I was selected.

He Yang is a senior graduate student, so I dare not offend him; behind the perverts in the experimental class stands an even more perverted one, so I dare not offend him even more.

Working silently is their best choice.

"Wang Zheng, what can I expect you to do?"

Department of Mechanical and Electrical Engineering.

office.

Du Guowang's face looked extremely ugly. He poked his finger at the forehead of Wang Zheng, who was standing in front of him with his head lowered like a primary school student who had made a mistake.

At this moment, Wang Zheng didn't dare to look up and make eye contact with Director Du.

"Director Du, Xie Wei said that the PLC project is suitable for controlling the production process of chemical products..."

Wang Zheng was wronged.

Really.

If I had known that Xie Wei's real purpose in being familiar with all departments was to get in touch with the Chemistry Department, I would never have taken him to the Chemistry Department office.

Xie Wei is such a cunning guy!

Playing the trick of repairing the plank road in the open while secretly marching through Chencang.

When Wang Zheng learned that Xie Wei had taken several students from the experimental class to the chemistry laboratory, he realized that he had been careless and would definitely face the wrath of Director Du.

For a long time before the start of school, Director Du was on guard against other departments trying to snatch his students away, and had never allowed anyone other than the Liang brothers and sisters to come into contact with Xie Wei.

Now, on the first day Xie Wei arrived at school, he went to the chemistry laboratory.

It was Wang Zheng who brought me into contact with the Department of Chemistry!

Obviously, Director Du already knew that it was he who brought Xie Wei to the Department of Chemistry.

"Leader, didn't you say that Xie Wei went to the chemistry lab? The principal made the final decision!"

Wang Zheng looked aggrieved.

"Do you think I came to you for this problem? Damn it! I was discussing cooperation plans with the leaders of Harbin First Machinery, what did you do? I asked you to cooperate with Xie Wei to set up the framework of the PLC R&D team first, what's the progress?"

Du Guowang's face became even uglier.

After Xie Wei proposed "independent project establishment, self-financing, independent management, and self-responsibility for profits and losses", Principal Li Rui went to the ministry to ask for policies.

Du Guowang was naturally not idle either: for several consecutive days, he knocked down the relevant persons in charge of Harbin First Machinery one by one at the dinner table. Finally, Harbin First Machinery agreed that as long as the Mechanical and Electrical Department developed a CNC numerical control system, it would spend money to purchase it.

It was also agreed to send technical personnel to be responsible for the technical research and development of machinery.

Du Guowang returned to school and Xie Wei was gone!

"I looked for him several times but couldn't find him! Not only me, but Teacher Liang also got angry in class because Xie Wei didn't show up for class." Wang Zheng defended with a bitter face.

"What can I expect you to do?"

Du Guowang glared at Wang Zheng and said unhappily, "How can a living person be lost? Go to his dormitory tonight and wait for him! If you can't find him, will he not go back to the dormitory to sleep?"

"..."

Wang Zheng’s face looked even more bitter.

I heard that Xie Wei always returned to the dormitory after two o'clock. Now that I have found him, I am afraid I will have to stay with him, otherwise he will disappear again tomorrow.

"I'm telling you, we have to pay attention to this matter. Put other work aside for now. Ha Yiji is waiting for our news!"

computer science.

Small conference room.

Four graduate students and several students from the freshmen classes of 4 and 77 who were valued by Yu Guofeng and had a good foundation were looking at the simple structural diagram drawn by Xie Wei on the blackboard and discussing in a low voice.

Yu Guofeng, who was sitting next to him, almost had his mouth cracked to his ears: Even though Du Guowang was as cunning as a devil, he has now been cheated by the foot washing water!
Director Yu had been going to Chengdu specifically before, but he never expected that Du Guowang got in touch with Xie Wei before him and brought Xie Wei back to school early the next morning. Yu Guofeng didn't even see Xie Wei in Chengdu.

Before school started, Du Guowang hid Xie Wei at home and forbade anyone to contact him. He also sent Wang Zheng to guard outside his house.

Yu Guofeng still did not give up at that time, and even rolled up his sleeves to fight with Du Guowang.

Finally, the principal made the decision and the experimental class was established.

No one can grab it.

There are currently no basic computer courses in the experimental class, and Yu Guofeng has almost given up on letting Xie Wei learn computer science.

Who would have thought!
The surprise came suddenly.

Xie Wei, who was supposed to be working in the chemistry lab making dishwashing liquid, came straight to the computer department and came up with a design plan - a calculator!

A calculator that can not only perform addition, subtraction, multiplication and division, but also perform complex operations such as exponentiation, square root, exponentiation, logarithm, trigonometric function, etc.!

Although Xie Wei calls this thing a calculator, it is definitely a computer!

Of course, Xie Wei is happy to be called that, and Director Yu supports it.

Even though Xie Wei called this an abacus, Director Yu thought there was nothing wrong with it.

A few days ago, Xie Wei found Yu Guofeng and said that he wanted to use a quiet environment to work out a structural sketch. Yu Guofeng didn't even ask him what he wanted to do and gave the office to Xie Wei without hesitation!

He even learned from Du Guowang and did not allow anyone to disturb Xie Wei.

Even lunch and dinner were brought from the cafeteria.

Now, the enormous wealth has come to the Computer Science Department.

"Xie Wei, according to what you said, the CPUs we have available now cannot perform such a large number of calculations, especially those involving logarithmic and trigonometric functions..."

"To perform exponentiation, root extraction, and even logarithmic operations, each operation requires different program control, and the memory needs to be increased a lot..."

"The instruction controller alone involves the program counter and instruction register..."

Those who were in grades 77 and 78 didn’t even understand the basic principles of computers and dared not say a word.

Although they didn't understand, Xie Wei sounded very profound when he spoke.

How dare you question randomly?

Yu Guofeng’s graduate students are different.

The level may not be high, but the foundation is not bad either.

At least, they have a good understanding of computer principles and basic theoretical knowledge, and they have even been involved in computer-related work before.

"Pah~pah~"

Xie Wei clapped his hands, interrupting several graduate students who were questioning him.

The small meeting fell silent.

Looking at them, Xie Wei said helplessly: "Seniors, I think you don't understand! What we want to make is just a simple calculator for mathematical operations, not a fully functional computer!"

"What? Xie Wei, do you know anything about computers?"

Graduate student Wu Hongbo was almost laughing out of anger, and angrily questioned Xie Wei: "You call this a calculator if it can perform operations such as logarithms and trigonometric functions? Do you know what a computer is?"
