The ups and downs of life in the Siheyuan

After discussing everything with Professor Xu, Li Yuan finally felt relieved.

After the meal, I wanted to leave, but was pulled into the study by Professor Xu.

Li Yuan originally wanted to help make tea, but he pushed him down on his seat and brewed a cup of green tea for him himself.

"Xiao Li, try the Dahongpao that my friend gave me."

Li Yuan picked it up, took a sip, and commented in Professor Xu's expectant eyes: "It smells good!"

"Gone?"

"It's so fragrant!"

Professor Xu looked at Li Yuan strangely, and then looked at the tea bowl in front of Li Yuan with pain.

"Hey, I'm sorry to disappoint you. I'm just a rough guy. I only know how to quench my thirst when drinking tea. I can be said to be the representative figure of cow chewing peonies."

Professor Xu nodded solemnly, picked up the tea can from the desk, turned around, put it in the bookcase, and closed the door gently.

Then he subconsciously patted the cabinet door.

Li Yuan couldn't help but smile, "Don't be heartbroken, I'll get you some good tea in the future."

Professor Xu looked disbelieving, sat down again, exchanged a few words, and got back to the topic.

"Now Big Brother's group is focusing on electronic tubes, and the West is focusing on transistors. Who do you think can win?" The old man turned his anger into a test.

"The transistor will win!"

“Electronic tubes are now very mature and the price is much lower than transistors.

In terms of signal processing, tube signal quality is better.

On the other hand, transistors are noisy and costly, and are not easy to produce on a large scale? "Professor Xu smiled with an inexplicable meaning.

“The advantages of transistors are unmatched by electronic tubes, such as power consumption. Transistors are only a fraction of electronic tubes.

For example, in terms of volume, semiconductors are far smaller than electron tubes.

For example, stability or lifespan are incomparable.

Therefore, once industrialized, transistors will quickly replace electron tubes."

Professor Xu laughed, "Yes, your knowledge of transistors has surpassed most people.

Now everyone is just getting started, but unfortunately we have insufficient investment, and the gap will become wider in the future."

Li Yuan also admired Professor Xu very much for seeing things very accurately.

As a person of later generations and living in this era, he does not think that the country's decision-making on semiconductors is wrong.

"Mr. Xu, how do you evaluate semiconductors?"

"Haha, I'm still trying to teach you, so I'll tell you.

During the first industrial revolution, the world entered an industrial society. Big countries used aircraft and cannons to seize the world's resources and became two powerful political groups.

The emergence of computers has accelerated scientific research, and I feel that the world is about to enter the second industrial revolution.

This time the representative must be represented by a computer.

I think this will bring unprecedented changes to the entire human society."

Li Yuan had to admire Mr. Xu's far-sighted vision. Living in the fog of the times, he had already seen through future developments and changes.

"I feel the same way. The 103 machine we just introduced and imitated has a computing speed of only dozens of times per second. In just a few years, we have exceeded 5 times per second.

Let’s not talk about the use of new technologies. As far as current tube technology is concerned, as long as we continue to expand the number of bus bits and increase the computing memory, it is not a dream to increase the speed by 10 times.

The speed of 50 operations per second will bring unimaginable changes to mathematics, physics, chemistry and other subjects.

Results will continue to emerge in a geometric progression.

This in turn will spur advances in computer technology.

This will enter a positive cycle, and technology will grow explosively in the future.

Once transistors mature and replace electron tubes, computers with miniaturization, low power consumption, and ultra-fast computing speed will appear.

What will happen then? ! "

After Li Yuan finished speaking, Professor Xu couldn't help but take a breath of air.

He is engaged in theoretical physics, and mathematics is a basic skill. He can deduce the consequences of Li Yuan's description with a little modeling in his mind.

His breathing was a little heavy, and Li Yuan hurriedly pushed his water glass in front of Mr. Xu.

Mr. Xu took a big sip of tea, held it in his mouth, tilted it slightly, and swallowed it several times.

He stood up and started walking around the study.

Coming to this era, Li Yuan discovered a phenomenon. Those engaged in scientific research like to keep spinning when they encounter problems.

Later generations do not spin in circles, probably because most of the work is done by computers and it is not easy to carry them around in circles.

"Can't wait, I have to do something!"

Mr. Xu turned around for a while, seemed to have made up his mind, looked at Li Yuan and said firmly.

Then he sat back in his chair, took out a pen and paper, and prepared to write something.

Although Li Yuan admired it, he had to remind him to cover the white paper with his hand.

Mr. Xu raised his head and looked at Li Yuan doubtfully.

"Mr. Xu, please say a few words before you think about how to write them."

"Oh, look at me. I don't care about others when something happens. I'm sorry."

After saying that, he put on the pen cap, put the pen on the desk, looked at Li Yuan, and stretched out his hand to signal.

"You're welcome, but what I say next may be wrong, so please bear with me first.

Let’s first talk about the current situation of our country.

1. The country is engaged in large-scale production and has encountered a natural disaster that is rare in ten years. Living materials are now extremely scarce;

2. The launch of 156 projects has made our country fortunate to move from an agricultural society to an industrial society in one fell swoop. However, with the complete withdrawal of Big Brother, we are faced with the dilemma of lack of technology, lack of management, and lack of funds;

3. Now we have to repay debts, and the main output is either natural resources or agricultural products;

4. What’s more critical is that we are currently short of people. College graduates and international students in recent years have been spread over 156 projects. How many people can be allocated to each project?

5. Nowadays, local governments are launching repeated projects, which is a huge waste of resources.

And the investment in semiconductors is huge. Do you think we still have the energy to engage in scientific research now? "

It's not that Li Yuan is awesome, but that he has the memory of later generations and has a deep understanding of this society, so he can see some things clearly.

Li Yuan's analysis made Mr. Xu deep in thought.

After a while, Professor Xu frowned and said, "The problem is, with the speed of semiconductor development, if you fall behind one step, you will fall behind step by step."

"I understand your feelings. Let's analyze the situation faced by the West.

1. The West has a lot of capital and is looking for investment directions;

2. Second, people in the West are relatively wealthy, and a large number of people and organizations are researching unprofitable transistors;

3. Western machinery is extremely developed, and their demand for automation is quite urgent;

4. Westerners are now in an era of extremely high curiosity.

Therefore, transistors are easy to iterate and optimize, and can be quickly put into practical use.

Then a market will be quickly formed, an industry will be formed quickly, and more capital will be attracted.”

Mr. Xu frowned even more tightly, "Are we just going to watch as we fall behind?"

"Sometimes, we have to do this. Now our country has no money, no talent, and no accumulation. It is difficult to compete with Western capital during the technology accumulation period.

But when their technology matures and we have accumulated a certain amount of wealth and talent, we will also have the opportunity to overtake them in a corner."

Mr. Xu shook his head, "No, in the foreseeable transition period of the second industrial revolution, we cannot fall behind, and we cannot give up this opportunity.

Just because we have less money does not necessarily mean that our planned economy is inferior to the market economy."

Mr. Xu seems to have regained his confidence. They have come through the most difficult times. When encountering difficulties, the first thing they think of is to overcome them. There is no possibility of retreating.

Li Yuan admired their courage very much, but he still didn't quite agree with it.

"Mr. Xu, have you ever thought about what transistors will bring to Western capital?

It is a huge wealth!

World War I and World War II were essentially the plunder of resources and the appropriation of resources by capital.

Once capital sees that we are a threat to them, what do you think they will do? "

"Hmph! When friends come, there's good wine; when enemies come, there's shotguns."
