The Grandmother in the Siheyuan

Chapter 205 The Clock That Never Falls Wrong

The first day of school at Huaqing University was very lively. Although it was not the twelfth month of winter, it was right at the end of winter, and school started in February.

Many people wondered why school started in February, because the document for resuming the college entrance examination was issued in October, so the exam was in December.

This is very reasonable, because after all, the notice was sent out suddenly, and many of these candidates may not have studied much in the past ten years, so these students who are preparing for the college entrance examination really tried their best during these two months.

These people can be said to have no foundation at all. Although the exams back then may have been relatively simple, they were able to get into university from zero foundation. Just think about how much effort they put in. So don’t say that the current college entrance examination sprint is cruel. It was even more cruel in 1977.

There were 5.7 million people who registered that year, but only 270,000 were admitted. This elimination rate can be described as a huge army trying to cross a single-plank bridge.

Young teachers like Liu Hua were mobilized to receive students who came to register. That year, Huaqing University enrolled more than 800 undergraduate students in the class of 1977.

Liu Hua was in charge of even fewer students, because most of them did not understand what semiconductors were. At that time, radios were called semiconductors, and many people thought that semiconductors referred to radios.

There were only twenty-one students assigned to Liu Hua's class at that time. Liu Hua looked quite young and was even regarded as a classmate by some students. This was because the oldest student taking the college entrance examination that year was thirty-six years old, and some students might have had two children at home by the time they went to college.

As the most professional teacher in the semiconductor field, Professor Li asked Liu Hua to give the first lesson to the freshmen.

In order to avoid embarrassing himself in front of the freshmen, Liu Hua spent ten points to exchange for a skill of writing on a chalk blackboard.

After writing his name, Liu Hua casually threw the chalk into the chalk box and began his opening remarks.

"A single spark can start a prairie fire." Liu Hua said with a smile: "As the first batch of students majoring in semiconductors, or computer hardware, in Huaqing University and even in universities across the country, although there are only 21 of you in total, I believe you will achieve great success in the future."

"Teacher, were you sure that we would achieve great success in the future?"

Liu Hua smiled and said, "I, Liu Hua's students, will not allow them to be mediocre. In the future, you will be the computer design talents of our country, and the country also needs you to be extraordinary."

This group of uninformed students were stunned by Liu Hua's domineering words.

"Does anyone know what the so-called semiconductor major is mainly about?"

Someone yelled, "Radio."

Hearing his accent had some southern Henan characteristics, Liu Hua smiled and said, "Hey, you can answer questions quickly."

The whole class laughed. Liu Hua tapped the blackboard and said, "I have a request for you. Since you have come to Beijing to attend university, you should learn Mandarin as soon as possible. It's not that I think dialects are not beautiful. Dialects are also an important way of inheriting and a part of our country's history and culture. But you have to facilitate communication. Our country is too big and there are too many dialects. I can still understand you when you speak southern Henan dialect. If students from Jiangsu and Zhejiang speak Wu dialect or Chu dialect, I won't understand them at all." Seeing the students nodding, Liu Hua continued, "Now, as a teacher, I will formally teach you. The so-called semiconductor major does not refer to radios alone. As a student of our major, you can't say that in the future. It's embarrassing."

"Semiconductor major is a very high-tech major." Liu Hua said directly: "So-called semiconductor major, what do you need to learn? Semiconductor materials, semiconductor devices, integrated circuit design, semiconductor manufacturing process, semiconductor packaging and testing."

"You also need to learn advanced mathematics, linear algebra, probability statistics, university physics, circuit analysis, analog electronics technology, digital electronics technology, etc."

Liu Hua slammed the table and said, "Perhaps you haven't realized yet how high-end and classy this major is."

"Let me tell you this. You must have heard of missiles, right?"

The students nodded, and Liu Hua smiled and said, "Missiles use electronic tubes and integrated circuits to control their flight trajectory. These are all semiconductors. If semiconductor technology is not developed, missiles will not be able to hit targets accurately in the future."

"Semiconductor technology will also be applied to radars, satellites, ships, aircraft, combat vehicles, tanks and even artillery shells in the future."

This opening remark directly aroused students' interest in learning. Many people did not understand what the semiconductor major was all about and were transferred here.

I was a little reluctant at first, but then I thought that Huaqing University was not bad, and if I missed this opportunity, I would miss it forever, so I decided to major in semiconductors and design radios.

Now that Liu Hua had said this, they became excited. It turned out that it was not a radio, but something much more advanced than a radio.

"What you need to learn is chips and computers." Liu Hua said with a smile: "In the future, you will develop new computers for our country. Maybe you will find this word unfamiliar, but I tell you, this thing will have a very wide range of applications around the world in the future. As long as you learn it well, you will not only embrace the future, but also embrace the whole world."

Professor Li had been standing at the door listening. He felt that Liu Hua had no previous teaching experience, so he was a little worried. If Liu Hua came to give a lecture and there were any mistakes, he could come in to save the situation.

Unexpectedly, Liu Hua became an instant hit and completely ignited the passion of this group of students.

Nothing serious was taught on the first day of class. Liu Hua was responsible for giving the students some basic knowledge about semiconductors.

Before the get out of class ended, Liu Hua looked at his watch, waved his hand and said, "The get out of class is almost over. I have a good habit of not staying after class. I hated staying after class when I was in school. So I'll stop here today. Everyone, be prepared tomorrow. I have discussed with our department head that we will visit the first computer researched by our school tomorrow, so that you can broaden your horizons."

Watching the second hand approaching, Liu Hua smiled and said, "I have also been eating in the cafeteria for several months. Let me give you a good suggestion. When you see meat dishes, don't be polite. Our cafeteria is a bit stingy. You have to be a little sweet-mouthed and try to get close to others. Otherwise, the chef's hands really have Parkinson's syndrome. A spoonful of meat can be shaken away and only a piece is left.

The second hand had passed sixty, but the bell had not yet rung. Liu Hua smiled and said, "The watch of this bell ringer is inaccurate. When you have learned semiconductors well, design a clock for me that will never have errors."
