After hearing Fang Xiaoyu's interested inquiry, Li Zhonggong introduced: "Cars and tractors running on the ground, airplanes and airships flying in the sky. New production methods in assembly line factories, new submarines and diving suits, PVC plastics and artificial
Rubber, and even better, we used transistors to create the first electronic computer."
Fang Xiaoyu's eyes gleamed when he heard: "There are so many good things. You are really amazing. Tell me about that electronic computer. How is its computing speed? How many additions per second can it do, and how big is it?"
Li Zhonggong said: "It's very fast, with 50,000 additions per second, but the size is not small, taking up a full fifty square meters. We also specially designed a large water-cooling circulation system for it to dissipate heat.
"
Fang Xiaoyu nodded. This result was much better than he expected. The first computer on the earth, 'Eniak', took up 170 square meters of space, weighed 30 tons, and its computing speed was faster than
The one produced by Zhonghua Ling is much slower, only one-tenth of his speed. But this is no wonder, after all, the 'Eniak' is a tube computer, while the one produced by Zhonghua Ling is a transistor computer.
Fang Xiaoyu told Li Zhonggong: "We must step up the development of this electronic computer and improve its performance as soon as possible. This is very important to us. Using it to perform data calculations in scientific research experiments can speed up scientific research a lot. If you want
The most important thing to improve the speed of electronic computers is to integrate transistors into circuits."
Li Zhonggong asked in confusion: "What is an integrated circuit?"
Fang Xiaoyu laughed at this introduction and said: "This is electrical knowledge, Tesla should be easier to understand."
Tesla spread his hands and said: "Master, your theory is too profound, I don't understand it."
Fang Xiaoyu said with a smile: "This is very simple. It means making the circuit board into a printed circuit board, making the transistors as small as possible, and then installing the very small transistors on the printed circuit board according to the pre-designed circuit, and then the circuit
The board is sealed, which allows the circuit to be disassembled, easy to detect faults, and easy to repair and replace. Moreover, because the transistors on the integrated circuit are very small, they generate little heat, which can greatly increase the life of the transistors."
Tesla nodded and said: "I understand the rest somewhat, but what is this printed circuit board?"
Fang Xiaoyu continued to explain: "When you make circuit boards now, don't you solder the transistors on the circuit board and then connect them with wires?"
Tesla nodded and said, "Yeah, what's the problem?"
Fang Xiaoyu smiled and said: "There is no problem, but there is a simpler way. You only need to design the circuit in advance, draw the required wires on the copper-clad circuit board, and then apply anti-corrosion on the copper sheets that need to be retained as circuits.
paint, and then put the entire circuit board into the acid solution. The unnecessary copper pieces will naturally dissolve in the acid solution, and the remaining copper pieces are wires. This can solve many problems and reduce the stress after making.
of circuit board weight.”
After listening to Fang Xiaoyu's explanation, Tesla slapped his thigh and said, "This is really a genius idea. My dear young master, how did you come up with it?"
Fang Xiaoyu said with a smile: "I just came out after thinking about it."
Tesla glanced at Fang Xiaoyu with envy and said, "I really wish I could have a mind as smart as yours. It's a great loss to mankind that you are not a scientist."
Fang Xiaoyu smiled and said: "Someone has described me like this before, but I think it would be a great loss for mankind if I gave up my current career."
After saying this, several people came to the factory area. Fang Xiaoyu was the first to jump out of the car and inspected the factory here accompanied by several other people.
The factory in the Wild Continent already has a very strong modern atmosphere. In Fang Xiaoyu's opinion, it is already as good as the old documentaries from the 1950s that he watched in his previous life. At least there are many machine tools here, busy assembly lines can be seen everywhere, and cars that use batteries are repeated over and over again.
Pulling goods, battery forklifts carry heavy parts.
After walking around, Fang Xiaoyu looked at several large factories such as automobile factories, steel plants, and chemical plants. As he walked, Fang Xiaoyu asked strangely: "What you just introduced are all civilian industries, and now you are also looking at civilian industries. Why?"
Didn’t the military industry hear you mention it?”
Li Zhonggong smiled and said: "It's better to look at the civilian ones today. It would be better to look at the military industry after the experiments tomorrow." Fang Xiaoyu also felt that it made sense, nodded and continued to visit.
There is a very modern four-story building at the northernmost end of the entire factory area, and it is surrounded by barbed wire and armed guards. Fang Xiaoyu wondered: "Why are the guards here so tight? The factory area is already very tightly guarded.
Well, why do we need to add another post?"
Tesla explained: "This is one of the most important research institutes in the entire wild continent. I am responsible for the research of electronic equipment. Our first electronic computer is also here."
Fang Xiaoyu said: "Really? We need to take a closer look at this. Let's go in."
After going through several security measures, Fang Xiaoyu and others arrived at the small building. He looked around and asked curiously: "What? It's empty here. There doesn't seem to be anything?"
Tesla smiled and said: "This place is hidden from others. Our laboratory is actually underground."
Fang Xiaoyu smiled and said: "You are really a little neurotic. Is it necessary for you to be like this when the Wild Continent is so safe?"
Tesla said: "Be careful and there is no big mistake. Let's enter the experimental base first."
Tesla pushed open a secret door on the left wall and walked in, and everyone followed. Inside the door were two elevators. Tesla led everyone into an elevator. There was a keyboard in the elevator.
After pressing the password, the elevator immediately started and flew downwards.
Sitting in the smoothly descending elevator, Fang Xiaoyu said with a smile: "You guys are so advanced here, it's like watching a science fiction movie."
Tesla wondered: "What is a science fiction movie?"
Fang Xiaoyu said: "It's nothing. It's a type of movie that I have conceived. The full name is science fiction movie. What I mean is that your place is a little too advanced. It is much more advanced than the world's leading technology."
Tesla smiled and said: "I see. In fact, these are the results of research based on the thesis you gave us, Master. These two elevators are the highest-tech crystallization of our laboratory. The production alone took a year.
That cipher disk is actually a mechanical device that is still used in other countries, but they only use it on the cipher box."
Fang Xiaoyu suddenly realized that what he was thinking was a bit complicated. Things that seemed very science fiction could actually be achieved by using the current level of science and technology to find another way. He just didn't know whether space flight could be achieved under the current technological conditions. Fang Xiaoyu thought of this randomly.
He laughed at himself, thinking that he was crazy for wanting to return to Earth, to have such a whimsical idea.
The elevator descended rapidly, and a few minutes later the elevator door opened silently. Behind the door were dozens of armed guards and two machine gun positions.
Fang Xiaoyu smiled and said: "Such security is too tight."
Tesla smiled and said: "This is completely a preventive measure. We are now more than two hundred meters underground, and we are surrounded by reinforced concrete walls up to ten meters thick as support."
Fang Xiaoyu said: "Let's go inside quickly and take a look." Under the leadership of Tesla, after passing several security checkpoints, everyone arrived at a busy laboratory.
Tesla smiled and said: "This is one of my electrical laboratories. They are currently studying radar systems."
Fang Xiaoyu said: "Has the research been completed?"
Tesla shook his head: "Not yet. Although a radar prototype has been built, clutter has a great impact on it. Not only is it difficult to find the target to be found, but even if you work on it for more than ten minutes, the soldiers will be cluttered.
The waves made me dizzy."
Fang Xiaoyu nodded: "The power is still not high enough, and filtering out clutter does take a lot of time."
Fang Xiaoyu knew in his heart that what such primitive radar lacked was the mature technology of magnetrons, but the technology of magnetrons was a bit too high for the current technological level. It was better to wait until he had time to propose some to Tesla or Einstein so that they could first
Conduct preliminary research, or let Xiaofeng conduct theoretical research to sort out the paper.
After walking around several rooms, the scientific researchers seemed to have not seen Fang Xiaoyu at all. No one raised their head to look at these people. They were all concentrating on doing experiments. Seeing the selfless work of the scientific researchers, Fang Xiaoyu nodded secretly.
At this time, Tesla pointed to the cluster of instrument cabinets in front of him and said: "Look, this is our first electronic computer. We all call it 'Huayu No. 1', which is named after the names of the Chinese leader and the young master."
The meaning of the word.”
Fang Xiaoyu said with a smile: "This is a good name, 'Huayu No. 1'. I hope you can build better and better computers, and not only the hardware, but also the software must be accelerated. Without good software support, the hardware cannot perform its best."
The most effective.”
Then Fang Xiaoyu explained the basic concepts and principles of software and hardware, which made Stella nod her head repeatedly. The entourage on the side were stunned for a while, and everyone secretly admired the young master as a superman who knew everything.
Everyone was casually visiting the laboratory, and Fang Xiaoyu asked in his mind: "Xiao Feng, what do you think of the electronic computer just now? Can you copy a clone of yourself into it?"
Xiaofeng was silent for a long time before replying: "Although it is possible, I refuse to enter."
Fang Xiaoyu asked strangely: "Why?"
Xiaofeng replied: "This computer is really too slow. It would be an insult to me if my clone entered such a computer."
Fang Xiaoyu said: "Then what kind of computer do you think is needed to match your identity?"
