This classmate doesn't know what your name is?Which department is it?" Huo Yaowen glanced at the male classmate curiously.

The male classmate shouted: "Professor Huo, my name is Liang Xing'an, and I am a sophomore in the Department of Computer Science and Technology of Peking University. ”

"It turned out that he was a student of the Department of Computer Science, and it seems that Liang is very concerned about the research of computer science and technology in the motherland, so I will briefly talk about the latest personal computer developed by Apple in the United States. ”

Huo Yaowen smiled slightly, and continued: "All the students here, I think many students are relatively unfamiliar with this word, except for the computer department or students who are interested in this aspect and know what a computer is. To put it simply, a computer is an electronic computer used for high-speed calculation, which can perform numerical calculations, logical calculations, and also has the function of storage and memory. ”

"Computers are very versatile, as far as I know, the U.S. moon landing program ten years ago used supercomputers to carry out numerical simulations, and accurately calculated the time and even the landing place of the moon. I don't know what it is, and NASA won't announce it. ”

"I once communicated with Conrad Chuzer, the father of digital computers, about the future and development of computers in the United States, and came to a very important understanding, that is, if the industrial revolution brought the foundation of modern society in the 20th century, then the birth of computers marks that the 21st century will be fully oriented towards informatization and digitization. ”

"Maybe you don't understand what informatization and digitalization are. To put it simply, the computer will become the most important weapon in the 21 st century, a national weapon no less than a nuclear bomb. With computers, we can accurately calculate the distance at which missiles are launched, we can also make more elaborate lathes, and even we study space, all with the help of computers. After all, manpower is limited, and computers can not only replace manpower, but also do what manpower can't reach. ”

"The personal computer, which I just mentioned, is a simplified version of a supercomputer, and as the name suggests, the personal computer is a computer that belongs to the general public, which can help us work better and better understand information that we would not normally know. ”

After Huo Yaowen's little by little narration, most of the students who came to listen to the lecture at the scene, except for a very small number of students from the Department of Computer Science, had a very vague concept of computers.

Liang Xing'an continued to ask: "Professor Huo, if according to what you said, personal computers will become world-changing products, then what do you think we should do?"

"Vigorously develop semiconductors. ”

Huo Yaowen thought about it and decided to talk about it, "The technology of producing computers is not particularly complicated, but it is more difficult to assemble computer accessories to produce them. At present, foreign research and technical control of semiconductors are not particularly strict, so it is the best time to vigorously develop semiconductors now to avoid the popularization of personal computers and information technology in the future, which will lead to a technical blockade. As far as I know, ITRI has been developing and researching integrated circuits since 76 years. ”

The side Huo Yaowen said was naturally Wanwan, but he was worried that there would be any impact if he said it, so he simply pointed to the south. The students here are all smart people, most of them understand in an instant, only a few did not react, and they also understood where it was under the reminder of their friends.

"Ahem......"

Suddenly a coughing sound came from behind the scenes, the sound was not loud, but it was enough for Huo Yaowen in front of him to hear it, he was slightly stunned, and then understood that this was Jin Kaicheng reminding himself not to talk too much about the other side of the strait.

Huo Yaowen diverted the topic, "Okay, I don't know much about computers, I can only tell you what I know, see and hear." If you are interested, you can do your own research on computer information and materials. ”

Liang Xing'an seemed to have something he wanted to ask, but he noticed that Professor Huo on the stage didn't want to continue, so he had to say, "Thank you, Professor Huo, I have no problem." ”

"Liang was able to grasp computers from a few sentences of mine, and he must be very passionate about computer technology. ”

Huo Yaowen touched his chin and smiled: "I myself have a computer company in the United States, and when I first came to Peking University, the university I have always dreamed of, there was nothing to give, so I donated 100 personal computers to the Department of Computer Science of Peking University for the research and use of teachers and students in the school." ”

Everyone doesn't know much about computers, and they don't know the value of these 100 units, but Liang Xingan, as a student of the computer department, although he doesn't understand the price abroad, the few large-scale computers in Peking University are astronomical, even if it is a simplified version of a personal computer, I am afraid it is a lot of money.

After talking about donating computers, Huo Yaowen didn't wait for everyone in the audience to react, and asked another student by name.

"Professor Huo, I am a student of the Chinese Department of Peking University, my name is Wang Hechang, I would like to ask Professor Huo, what is your view on reform and opening up?"

The student stood up and asked, which made Huo Yaowen a little overwhelmed. Good guy, worthy of being the first batch of Peking University pride in the eighties, asked a question that was enough to kill him.

Huo Yaowen hesitated for a few seconds, didn't hear Jin Kaicheng's cough behind him, and thought that Peking University was open to academics at this time, and there were many discussions on political issues, so he didn't care about the questions raised by this student.

Seeing that there was no problem, I could say it, Huo Yaowen sorted out his thoughts and replied seriously: "Of course, I am very optimistic about the reform and opening up of the motherland. Last year, when I accompanied my family from Hong Kong to visit relatives in my hometown of Zhongshan, Guangdong, I saw an article in the Guangzhou Daily about the content, and the content of the article is still fresh in my memory. Roughly speaking, the reform and opening up of the motherland can not only bring about a large amount of economy, but also make revolutionary progress for the further development of the country......"

In the past 80 years, the reform and opening up has begun to be carried out slowly, but in addition to the coastal areas, there are still a large number of people who do not understand this importance, although Peking University is one of the highest universities in the mainland, but limited by the times and the lack of information, the future road is not yet clear.

This is also why the student wants to ask questions, which Huo Yaowen can feel.

Huo Yaowen hesitated, but still said: "Maybe the students here only think that there have been some small changes in their understanding of reform and opening up, but in fact, in my personal opinion, if it is compared to a train, then at this time, everyone has just stepped into the train, and they have already seen the changes inside and outside the car before it starts."

But when everyone loads coal, the train starts slowly, then the scenery along the way slowly backwards, there is a clear difference, when the speed of the train is getting faster and faster, people will inevitably be attracted by the dazzling scenery outside the window, so that they forget to return, forget to add firewood and coal.

But in fact, there is still a long, long way to the terminal of the train, and the scenery brought by this road is only temporary, only everyone does their best to add oil and coal, and when they reach the final destination, they can see a wonderful and splendid new world. ”
