Chapter 361 Two Courses

The other courses are either relatively simple or not suitable for Beijing University of Technology, or they are not systematic and can be taught by other teachers.

However, although only a small part of this book "Principles of Automatic Control" has been completed, it is enough for teaching students. It is just right to complete it while learning.

Moreover, this book is of great significance. At this time, automation is even more important than computer science, because it has a wide range of applications, is closer to the existing technological environment, has a lower threshold for application conversion, and can penetrate into all aspects of industry, agriculture, military and other industries.

In fact, in Gao Zhendong's previous life, there was basically no difference in the employment directions of electrical automation and information technology majors in ordinary enterprises. Except for some industries and positions with special requirements, in general, the employment scope of automation is slightly wider.

At this point, we have to talk about the value of "DoubleE" (Electrical Engineering). It is a panacea that can do everything.

In a word, in Gao Zhendong's opinion, "Principles of Automatic Control" is more important at this stage.

"Dean Dai, I do have a course that I think would be a good fit for you."

Dean Dai never expected that Gao Zhendong was actually willing to attend class. His original idea was to just reserve a spot first. He didn't know what the Defense Work Committee was considering, maybe for safety reasons or something else, so they asked them to arrange a lecturer first. Gao Zhendong felt embarrassed to attend class with this teaching position.

In fact, the idea of ​​the Defense Work Committee leaders was not complicated. They wanted to wait until Gao Zhendong had taught for a period of time and then promote him in the name of teaching. This way, he would not be so conspicuous, especially in the eyes of the enemy.

Gao Zhendong could guess this, and he had no objection at all. Some people were willing to disappear from the world for decades, so it was no big deal for him to be a lecturer, as long as he could teach.

Since Chief Engineer Gao has already offered to attend the class, it would be foolish to turn it down. No matter what the class is, it should be extremely useful.

"Chief Engineer Gao, what kind of course is it? Let me see if our school can make some preparations first." He certainly wouldn't be stupid enough to call him "Lecturer Gao" the moment he opens his mouth. That would be like someone giving you a face but you taking advantage of it. It would be safer to just call him by his title.

"'Principles of Automatic Control' is a course that focuses on the basic principles and applications of automatic control. It is close to my original major, and I think it is also consistent with the teaching needs of the University of Science and Technology. I think there must be similar courses in the original school, but I combined my own learning and practical thinking for this course and carried out some systematic integration, covering classical control theory, time domain and frequency domain analysis of linear systems, root loci, correction, linear discrete systems, nonlinear control systems, state space analysis of linear systems, optimal control theory, etc."

As the head of a college, Dean Dai is very knowledgeable about automatic control. When he heard Gao Zhendong's choice, he was a little unsure. If it was a new subject created by Gao Zhendong himself, it would be fine, as he has the final say on these things, such as C language.

However, as a course that has been developed for quite some time, Principles of Automatic Control is not too old, but it is not too new either. Gao Zhendong himself has just graduated for less than a year. Can he grasp it?

It is normal to have such doubts, but blindly following others is not a good idea.

However, Dean Dai did not directly raise his doubts, but took a detour.

"Chief Engineer Gao, sure, sure. Then can you see if the textbooks here are ready? If they are, I can take them back and ask the school to make a batch. We can't have you making textbooks while you teach. That would make our school a laughing stock."

Nowadays, it is not uncommon for teachers to compile their own teaching materials. Many pioneers have returned from abroad. To be able to return from abroad was already a result of overcoming numerous obstacles, going through untold hardships, and giving up a lot of things. It is extremely difficult to bring back teaching materials from abroad.

So, hey, after I came back, I wrote my own stories. The things are in my head, and you foreigners can’t do anything to me.

For Beijing University of Technology, it’s just textbooks, so what is the purpose of the school-run printing factory?
Besides, considering the enrollment scale at that time, if the print quantity is really too small, it is not impossible to start the printer and print dozens of copies.

In this way, the teaching materials will be available first, and if it is determined that there are any problems, plans can be made in time.

Since Gao Zhendong said that he wrote the textbook himself, his level can be directly reflected from the quality of the textbook.

Gao Zhendong nodded and said with a smile, "It is now halfway done. Fortunately, I originally planned to divide this course into two semesters, so it is not bad to prepare the teaching materials for this half first."

He turned around, opened the safe, and pretended to take out a tape and a stack of carbonized paper.

"This is the first half. I divided it into five chapters. This tape contains the text part, and these papers contain all the illustrations and tables with their positions marked. Putting the two together will make up the first half of this textbook."

The editing programs at that time could not support the insertion of graphics and tables, mainly because the computer itself could not support pictures.

If tables can be barely supported by tabulation, pictures are in trouble for the time being. BMP and jpg are still not available. The main reason is that the machine can't handle it. If it is not compressed, the storage is difficult. If it is compressed, the computing power is not enough. As for tabulation, it was rarely used in Gao Zhendong's previous life. In the early days, software such as WPS under DOS had this thing. In fact, ASCII can barely achieve this effect. For example, if you have studied computer science and have used RFC (Request For Comments) documents, you will see a lot of similar tables in them.

But this effect is a bit ridiculous if it is used for publication.

Therefore, Gao Zhendong hand-drew all the figures and tables in the textbooks.

Dean Dai took it with a look of surprise. Although it was impossible to tell how many pages there were from the tape, it was clear from the number of illustrations and tables that the content should be very rich. There were even a large number of complex formulas that were purely handwritten because the editor did not support them.

Based on Dean Dai’s experience, we can tell from these formulas that this book is not simple!
He didn't know that this half of the book basically had almost 50 words. Chinese characters were represented by two bytes per character, which almost filled up the high-density tape.

"Principles of Automatic Control" (Volume 1), which would become the "favorite" of automation students in the future, was born!
The two discussed some details, and Dean Dai returned to school with the manuscript of the book given by Gao Zhendong.

In addition to "Principles of Automatic Control" (Volume 1), Gao Zhendong also commissioned Beijing University of Technology to publish another book he had drawn before, "Data Structure" (C language version). Now with the gradual popularization of C language, this thing can be put on the agenda. It is one of the basic knowledge for programmers.

Starting from the next semester, Gao Zhendong will teach at Beijing University of Technology as a lecturer, with three classes a week, concentrated in one and a half days, two of which are "Principles of Automatic Control" and one is "Data Structure".

There is only one class, and the size of the class can be decided by Beijing University of Technology. It can be 30 or 300 people, as long as the classroom hardware conditions are up to par. Anyway, for Gao Zhendong, it makes no difference whether he lets one duck go or drives a flock of ducks.

Dean Dai held two heavy documents in his hands. He thought, why bother printing internally? He should organize people to proofread them before the two or three months before school starts and publish them directly. The Defense Engineering Press is no worse than the Mechanical Engineering Press.

Inadvertently, "Principles of Automatic Control" returned to its original birthplace, which may be regarded as God's will.

He is now very confident about the quality of these two textbooks by looking at the paper charts.

After seeing off Dean Dai, Gao Zhendong felt relieved of one thing. He was making better and better use of the treasures he had drawn.

At the same time, somewhere in the capital, people from the Foreign Affairs, Foreign Business, and Defense Committees were holding a meeting.

Ministry of Foreign Trade: "Hong Kong Island and Southeast Asia have shown great interest in our DJS-59, Chinese character environment, and printers. What do you think?"

There is no need to mention Hong Kong Island. We also have a large number of overseas Chinese in Southeast Asia, so it is normal for them to have some interest in it.

After that, he added: "Especially in Hong Kong Island, they are very proactive."

The people from the Defense Committee laughed and said, "Haha, the enemy is not stupid either. It seems that John Bull saw or used it from the Gallic Chicken."

The person from the foreign affairs department laughed and said, "What do you think of this matter from the Defense Work Committee? Will it have any impact?"

The Defense Committee shook their heads and said, "No problem. If there was a problem, we would have stopped it long ago. The performance of the DJS-59 is not outstanding, but its ease of use is outstanding. This has no impact on the fundamental change in strength. The key is that we have better ones!"

The foreign affairs department nodded and said, "That's good. This also helps us to promote our character encoding. It contains more than just Chinese characters. Once you are used to something, it is difficult to change it. This still has some additional significance for us."

The Defense Work Committee smiled and said, "In fact, just in the past few days, our researchers have come up with two more computer-related things that are very useful in communications. You can consider adding them to your sales list."

The foreign business department staff got excited when they heard this: "It's computer related? Who did it again?"

The Defense Work Committee nodded and said, "Well, these two things are very interesting. You can sell them together with the DJS-59, or you can sell them separately as software!"

The two things he mentioned are the "telegraph digitization communication machine" software developed by Gao Zhendong and the Institute of Communications, and the complete set of email programs developed by the Institute of Computing. Although the latter has not been completed yet, there is no problem in putting it on the list.
