Immediately, Tesla couldn¡¯t wait to ask: ¡°How should our research work be carried out?¡±
"I have always believed that the difficulty in developing electronic computers lies not in the principle, but in the related components. The most basic is the realization of the three logical relationships of AND, OR and NOT. I just saw that you have used a resonant circuit to realize AND. This is the first step to success. However, this is not enough! Because developing an electronic computer is a huge and systematic project, and relying on you and me alone will be a drop in the bucket. If you want to succeed, , there must be a research group with a large number of people, a clear division of labor, and each with specialties to be effective." Sun Yuanqi analyzed.
In fact, this is the case. Eniac, the world's first electronic computer, used a total of 18,800 vacuum tubes, was 50 feet long, 30 feet wide, occupied an area of ??1,500 square feet, and weighed 30 tons. To put it into perspective, it is as big as a classroom and a half and weighs six adult elephants. And it consumes so much power that it is said that every time it is turned on, the lights throughout West Philadelphia will dim.
Tesla nodded silently.
"I have always been concerned about the development of electronic computers. In 1900, I established an electronics laboratory with MIT. The main purpose was to develop related components. So far, I have made great achievements and obtained a large number of invention patents including diodes and transistors. Of course, the team that studies components is only part of the project. I also established an electronics laboratory at China Jingshi University, and I want to focus on studying the electrical characteristics of various large-scale logic devices." Sun Yuanqi began to draw a picture, "If two If the laboratory work is carried out smoothly, it is optimistically estimated that preliminary results will be achieved in the next ten to fifteen years. However, the laboratory in China has just started and needs an outstanding scientist like you to lead the laboratory's research work. .If you can join, it will be our greatest honor!"
At the end of the sentence, Sun Yuanqi¡¯s fox tail finally leaked out, revealing his solicitation intentions.
At this time, the leader hesitated: "Yanke, your suggestion is very good. Researching electronic computers does require a huge team, and I also want to participate in it. However, I can't get away now"
"Can't get away? For the greatest invention in your mind?" Sun Yuanqi asked.
The leader nodded and shook his head: "That invention was indeed the greatest in my mind before. I want to build a tower and use it to resonate with the earth's ionosphere, so as to obtain a steady stream of electricity and provide it to the world for free. For everyone to use. To this end, I successfully persuaded Mr. Morgan, the famous billionaire and a "generous" scientific funder. He gave me a grant of $150,000 to build this experiment. room and the 187-foot-tall iron tower outside.¡±
Sun Yuanqi thinks this is the most sci-fi color! Not to mention the beginning of the 20th century, even the beginning of the 21st century could not realize the grand wish of the leader. Even if it can be realized, in China, the gentlemen of Guodian and Nanjing Electric Power Co., Ltd. who eat monopoly food until they die and drink the blood of the people until they die will not be willing to see this kind of thing happen. They who keep claiming to represent the national interests must be They are trying every possible means to obstruct it, let alone the capitalist plutocrats? Master Ma has clearly pointed out: Capital comes to the world, from head to toe, with blood and filth flowing from every pore. So Sun Yuanqi couldn't believe it, and asked tentatively: "Mr. Tesla, you proposed this idea to Mr. Morgan, and he clearly expressed his support for your research?"
"How is that possible? He thought I could achieve wireless communications with this project!" Tesla winked slyly at Sun Yuanqi. "Mr. Morgan, like Edison, was more interested in the commercial value contained in it, so he invested in it. . You know, because of this investment, he can own 51% of the laboratory's shares. In other words, he must have a share of any patent obtained by the laboratory."
Sun Yuanqi then nodded: Let me tell you, those businessmen and chaebols, even if you feed them Shiquan Dabu Decoction every day, you can't make up for the lost conscience!
Seeing that Sun Yuanqi remained silent, Tesla quickly added: "Of course, these are all my previous thoughts. Ever since I saw your monograph, I have regarded the invention of electronic computers as my lifelong mission. Although I can't get away from it for the time being. , but my project has achieved partial success. I believe that if I tell Mr. Morgan the content, he will let others intervene in this research and obtain the patent on his own. If we can really get free electricity, even if we charge part of the patent fee, we can Let more people enjoy the benefits brought by scientific progress."
Sun Yuanqi thought: All power companies and chaebols, including Morgan, do not want free electricity. If Morgan knew what you were thinking, he would immediately stop any funding for the experiment to avoid the project's success. At that time, with the leader¡¯s business skills,With the power, the bankruptcy of the laboratory may be just around the corner!
Thinking of this, Sun Yuanqi stood up, shook hands with Tesla and signed the contract: "After I return to China, I will complete the preliminary preparations for the electronics laboratory as soon as possible. As you just said, we should stop fantasizing and concentrate. I hope there will be One day we worked side by side on this great invention!"
????????????????????????????????????????????????????????????????????????????????????????????????????????????????? ?? The location where the laboratory is located is very remote on Long Island. The teacher and student walked for a long time before getting on the carriage.
At this time, Liu Bin, who had remained silent, suddenly asked: "Sir, what's the use of that?" Although Liu Bin didn't say what it was, Sun Yuanqi knew that he was talking about an electronic computer.
Yes, what is the use of electronic computers? Dr. Mauchly and his student Eckert designed the electronic computer at the request of the U.S. military to calculate the trajectory of artillery shells. What's the use of studying him yourself? Internet connection? That is something that is out of reach. Whether I can see it again in my life is still up to two people. As for the near future, it seems that the emergence of electronic computers can only make calculations faster, but other than that, it seems to have no greater use.
?????Does China need faster computing machines now? It seems that in China now, an abacus has solved almost all problems. A single abacus can't solve the problem, so the worst thing is to add a few more. Anyway, what China lacks most is people. Even in the history of researching two bombs in the 1950s and 1960s, it was not said that electronic computers must be used. On the contrary, a large number of calculations were completed by hand-cranked computers. See, there is strength in numbers!
Sun Yuanqi was stunned by Liu Bin's question. After a long while, he asked: "Then what do you think is useful?"
Liu Bin's eyes gleamed with scorching light and he stared straight ahead: "Our school is called 'Jingshi University', and the school motto is 'Jingshi is practical, strengthening the country and benefiting the people'. In my opinion, only those who can 'pull practical' and can' Things that "strengthen the country and benefit the people" are useful. And "strengthening the country" comes before "benefiting the family". Now everyone says that the country is dying! The country is dying! Naturally, no matter what we learn or do, we will always We must first ask whether this can save and strengthen the country.
"There is an allusion that a man named Zhu Hongman spent thousands of taels of gold to learn the skill of slaying dragons from a man named Zhiliyi. He studied for three years and finally succeeded after his family's wealth was exhausted. But after he came back, he found that everything was useless. No, because there are no dragons in this world! I heard the conversation between you and Mr. Tesla just now, and I thought of this allusion at that time. Isn¡¯t the electronic computer the skill of slaying dragons?
"If you ask me what I think is useful, I think the most useful thing now is the people and weapons that can defeat the great powers on the battlefield! If you tell me otherwise, I don't believe it. You can't find a million-blooded man among the 400 million compatriots! The most important thing is weapons. I think most of the defeats against the great powers in recent years were caused by backward weapons. As long as we can build guns that can shoot more accurately, cannons that can shoot farther, and ships with larger displacements, we will surely Can defeat the great powers and regain the country!"
Sun Yuanqi had a hint of enlightenment while listening, and said to Liu Bin in harmony: "Jifu, I don't know how familiar you are with firearms. I'm just talking about my layman's knowledge of firearms. Can you take a look, right?"
Liu Bin nodded silently.
Sun Yuanqi is neither a common gun enthusiast among time-travelers, nor a police officer, an officer, or a special forces soldier. He is really a layman when it comes to ordnance. Except for handling a gun during military training in college, I have only seen it in movies and TV. But the simplest truth can be imagined:
"A good firearm is definitely not achieved overnight. If you want to shoot more accurately and shoot farther, from design to production and finalization, you must go through countless rigorous tests and modifications. How to test? You know, whatever A small modification may lead to a series of other problems. You can't just change a little and just produce a sample, right? If the gun sample can still be produced, what about the ship? What about the aircraft in the future? At this time, we will It is necessary to use a tool to calculate the possible results after modification based on the existing data. After gradual matching in the early stage, my computer can finally become this useful tool. With it, future tests , modification can get twice the result with half the effort. This is only one aspect of the use of computers. For example, in the smelting and casting of steel for making guns, calculation and modeling are definitely indispensable.
"Furthermore, it is the human factor. The Chinese people are not enlightened. This is a topic that everyone has been talking about for a long time. In addition to education, we must awaken the people's understanding of science and culture through some big projects and achievements, and then have a better understanding of science and culture. The country and the nation generate identity.¡±
While talking, the carriage has arrived at the hotel where they are staying. After getting off the bus, both teachers and students looked thoughtful and returned to their rooms. Sun Yuanqi didn't know whether Liu Bin had slept well or not, but he himself stayed up all night, with Liu Bin's questions always ringing in his ears:
"Teacher, what's the use of that?" (To be continued. If you like this work, you are welcome to come to Qidian (qidian.com) to vote for recommendations and monthly votes.
