Go back to the past and be a schoolboy

"What, you haven't heard of the radio yet? Mr. Wu, Mr. Wu, you are so old-fashioned. You don't know about radio? This is the most fashionable novelty in today's society. How do you say it? Know the taste, can't stop!"

"Is... really so amazing?"

"Our two brothers grew up peeing and muddy, how can this lie to you? To tell you the truth, listening to the radio can not only listen to news, but also listen to operas. Don't look at the small box, there is a big world hidden in it, you Know what that means?"

"What does it mean?"

"It means that broadcasting can reform the family and slowly shape it into a new type of family. Professor Cheng said in yesterday's broadcast that the emergence of broadcasting has made the residence a center of information exchange like the ancient market, changing... hiss, Anyway, that’s what it means, as long as you know it’s important.”

"Oh, let me go. It's only been a few days since I went back to my hometown. How come I feel that the world has changed a lot after I came back."

"Isn't that right? Especially the female announcer called... the voice is like an oriole bird, and the bones in my ears are crisp when I hear it. Why do you think Professor Cheng is so powerful? This novelty The technology can be researched. I didn't like 'Mr. Sai' at first,

It’s okay to say that I don’t like ‘Mr. Sai’. Anyway, I have always been unable to love new technologies and feel that they are too far away from us. But Professor Cheng’s broadcast is really different. This is a real way to let us know ‘Mr. Sai’ 'It's amazing. "

"Then you said that such a powerful thing can be touched by us ordinary people?"

"This is what I said. If you want to listen, go directly to Central Park. There are two hours of radio time at noon, which is enough for you to listen to it for a while, but after all, you can't stay at home outside. This time, I plan to study the radio in the past. When I go home, I will also set it up. One, if it works well, put it on my eldest niece too."

"Then I can first thank you for being an uncle on behalf of my daughter..."

The two talked enthusiastically in front, while Cheng Nuo listened with gusto in the back.

It’s not that he likes to listen to the walls behind him, it’s just that the two elder brothers are talking too loudly when they talk about it, and with their slightly exaggerated body movements, it’s really hard not to be able to act in the mimes of this era. Attract the attention of passers-by.

But even so, Cheng Nuo didn't have the nerve to continue listening for too long. After learning a little about the content of the broadcast, he quickly passed the two of them and walked ahead.

Things had developed to this day, and even though he had tried his best to elevate the power of radio, Cheng Nuo realized that he still underestimated the effect of radio after he really understood it.

People talked about it everywhere, especially the content of storytelling that was broadcast inside, and the topic level was unprecedentedly high. There was a feeling of talking about yesterday's cartoon head-to-head before elementary school in the previous life.

Although the journey home was not short, what I could hear was the radio content. I even saw some parents sitting their children on their necks and dragging their wives to Central Park. It was a joyous experience.

But thinking about it carefully, in the previous life, Cheng Nuo had never experienced the "three turns and one sound" era of the "four major items" of the first generation, that is, radios, bicycles, sewing machines, and watches. How could he realize the importance of broadcasting and supporting radios.

"The Yali mountain is so big!"

Standing at the door of the house, Cheng Nuo glanced back and couldn't help complaining.

It just happened by coincidence that just as Cheng Nuo finished packing up and was about to open the door to go home, the door opened automatically as soon as he put his hand on it.

It's not that the door will automatically sense, but that an acquaintance just happened to come out from inside.

"Cheng...Professor Cheng? You're back?" the visitor asked in surprise.

Cheng Nuo, on the other hand, gave the visitor a big hug with a kind face: "Qisun, long time no see? I thought you had already gone to the United States to study, but I didn't expect you to be still in China now."

Ye Qisun was a little restrained: "Hurry up, the ticket has been bought, and we will leave in a few days. I was a bit regretful that I couldn't see Professor Cheng before I left. I didn't expect you to come back."

Cheng Nuo was a little emotional: "Yes, I'm back, I still have to come back to do some things, it's more reassuring to do it myself."

However, seeing Ye Qisun's hasty look, Cheng Nuo asked again, "What's the matter, I'm sure you didn't just come to see me this time, did you have a problem with mathematics, or do you have some experience in physics?"

Ye Qisun shook his head: "None of them?"

Cheng Nuo asked curiously, "What is that?"

Seeing the hesitation on Ye Qisun's face, Cheng Nuo smiled again, opened the door and pointed inside and said, "Come on, it's not convenient for me to see it here, let's go into the yard and close the door."

Seeing this, Ye Qisun breathed a sigh of relief, and took the initiative to follow behind and close the door.

After walking to the office, Cheng Nuo went to the kitchen and picked up a piece of briquettes, lit the stove in the room, and sat on the kettle, and the room gradually warmed up.

Originally, Ye Qisun wanted to rush to do this job, but it was a pity that there was no contest, but it was uncomfortable to sit and sit, and awkward to stand and stand, and suddenly remembered that he was carrying a bag, so he quickly took it off and put it on the table.

"Professor Cheng, in fact, I came here this time to say goodbye, and secondly, for the radio."

"Oh? You are also interested in radio? That's good. Sound, light, electricity, heat, and force all belong to the category of physics, while radio belongs to electricity. If you are interested, you can learn more about it." Cheng Nuo heard the news Very happy, after clapping the ashes on his hands, he specially instructed: "Take it as a hobby, not as a main business."

"You told me this truth before, do what you are good at and like." Ye Qisun's face darkened, but after looking at his satchel again, he cheered up and said, "Professor Cheng, in fact, I am here this time. Entrusted by Tsinghua students, they wrote many letters to you, and I brought them here this time."

After saying this, Ye Qisun opened the schoolbag, held the bottom and shook it upside down a few times, and dozens of letters were immediately thrown out from Lima, piled up into a miniature hill.

Cheng Nuo took a deep look at the other party, and Ye Qisun also felt a little embarrassed, and quickly added: "The students really admire you, and they all want to have some learning exchanges with you, and they all have good intentions. "

"Haha, of course I understand this, but I didn't expect there to be so many. I actually underestimated myself." Cheng Nuo said with a smile.

But to be honest, Cheng Nuo was very happy to see these letters, so he picked up one and looked at it carefully.

"Competition in the [-]th century is based on intellect, not physical strength. The previous concept of education has long been outdated. It cannot be limited to students reading and literacy in school. There is a radio program that teaches you. The objects of education are instantly expanded to all the people. The content is all life, and the place of education is the whole society..."

Continue to look through one more, which also has similar content:
"Our culture is backward, people's wisdom is not developed, there are many illiterates, and the traffic is very blocked. Therefore, the shortcomings of disseminating knowledge through printed materials are particularly obvious in our country. The promotion of broadcasting education is especially necessary in our country..."

Looking down, in addition to admiration, these students even came up with some genius ideas, expressing their willingness to go to the radio station to be a temporary host, passerby A popularizes weather information, passerby B talks about mathematics, and passerby D studies science and culture ... After careful calculation, two hours is not enough for these students.

"Your students' ideas are very good. I didn't even take into account these details, but let's talk first. The most important condition for an announcer is language. An excellent announcer must not only be able to speak Mandarin fluently, but also the language and art of broadcasting. And overall quality, it's not as simple as you think." Cheng Nuo laughed.

Regarding this question, Ye Qisun seemed to have been prepared for a long time, and said with a pat on his chest, "Of course I know this. For example, in the storytelling I told about some time ago, no matter how wonderful the words on the original paper are, it can't compare with the impassioned and rigid words spoken by the announcer." It's great when the news turns into a living story."

After the call, Cheng Nuo was surprised to find that broadcasting was also unusually popular among students, but thinking about it carefully, the younger he was, the more curious he was about new things, and the faster he accepted them.

"However, I didn't send someone to install ore radios in Tsinghua University. Where did you hear the radio?" After reading several similar letters, Cheng Nuo temporarily put down the letter and asked curiously, "Could it be that you all assembled it yourself?" ?”

Ye Qisun nodded fiercely: "Yes, after our classmates learned about the radio, and learned the principle through your article, they assembled one by themselves. Although the listening effect is not as good as that of the Academy of Sciences, it can also be listened to. Basically, a few classmates gathered together Together we can assemble one."

Cheng Nuo couldn't help laughing and said, "No wonder there is such a saying, 'Peking University is poor, teachers are poor, and only Tsinghua University can accommodate'. Your Tsinghua students are still relatively rich, and some parts are still not cheap."

Ye Qisun didn't refute this, and after thinking about it a few times, he also laughed.

Just at this moment, there was a sudden knock on the door.

"Come in directly, the door is not closed."

"Then I'm coming in." Opening the door curtain, it was Jiang Jiangzuo who came into view. After seeing Jiang Jiangzuo sitting in the room, he was surprised and said: "Xiaoye hasn't left yet, I thought you wouldn't be able to wait until the courtyard." Long, just left."

Cheng Nuo took the initiative to explain for him: "I was going to leave, but I happened to meet me at the door. Have you arranged other things? What are you looking for me this time..."

Before he finished asking, Cheng Nuo knew Jiang Jiangzuo's purpose.

It wasn't because he had the ability to read minds, but because the pile of letters Jiang Jiangzuo was holding was too conspicuous, and Ye Qisun was sitting next to him, so Cheng Nuo could almost tell that the other party was also here to deliver letters.

When asked, it was exactly as expected.

"Mine are different from Xiaoye's. Although they are all letters, their sources are more complicated and closer to our compatriots at the grassroots level." Jiang Jiangzuo patted the stack of letters and introduced: "This is still part of it. I want to If you look at it, the 'big troop' can come at any time."

Cheng Nuo waved his hand lightly, took the top copy in his hand and said, "These are enough for me to read for a while, and the rest will be troublesome to other comrades. If you encounter some interesting or common problems, you can put them on our list." In the "National" magazine, there will be a column of letters from readers dedicated to publishing these contents."

Although Cheng Nuo was already looking forward to these letters, after he opened them and read them, he still felt admiration. The wisdom really came from the people.

It turned out that the content of the letter was to a friend named Zhu Jun. After reading about the production method of the ore radio in the "National" magazine, and hearing a friend who returned from a business trip in Beijing talk about the magic of radio, he felt very itchy.

After the successful restoration, I found an easier method, and shared my method and process of making ore radios, expecting more people to use ore radios.

I bought ore from a pharmacy, and went to a foreign company to buy a receiver, plus the ready-made paper tubes, paper knives and copper wires at hand. The cost was only a few yuan, and I made a radio out of these small items, and even returned it specially. A structure diagram is attached.

"Okay, whether we were studying chemistry or mechanics before, to put it bluntly, our compatriots couldn't participate in it. This friend's letter inspired me. Let's hold a national science and technology competition through radio and magazines. , the main content is the optimization and design of ore radios, what do you think?"

"Technology competition? This is good. Although not many of our compatriots have attended school, the structure of the ore radio is not complicated, and the threshold for getting started is very low. I believe that many people are willing to participate in this event." Jiang Jiangzuo His eyes lit up, and he said excitedly: "Support, I raise my hands to support."

Ye Qisun was also a little moved, and after hesitating for a moment, he quickly said: "This competition should not be limited to participants, right?"

Cheng Nuo pretended to be serious and said, "Science and technology competitions are not child's play. Of course, they must be taken seriously. Participants should be screened."

Ye Qisun asked anxiously: "Huh? There are still restrictions on the participants? Then can us students participate?"

Seeing that the other party took it seriously, Cheng Nuo hurriedly said: "Of course I can participate. We only limit the competition to Chinese people, and only Chinese people can participate."

Jiang Jiangzuo agreed: "The purpose of the competition is also to let more people enjoy the changes in life brought about by technology, especially the current radio broadcasting, which will definitely be an important way to enrich the spiritual life of Chinese people in the future. I have no restrictions on this." Opinion."

Thinking about how many people in the previous life held the radio to learn about the outside world, and even learned English through the radio, the practical significance behind it is very great.

And Cheng Nuo also wanted to pave the way before the "National" broadcast was officially launched, so that it would be smoother in the future.

After discussing the entry process and entry rewards, Jiang Jiangzuo suddenly asked: "But how should the judges be selected? If we are all here, and we are both athletes and referees, I am afraid it will not be convincing."

At this point, Cheng Nuo suddenly smiled and said, "Didn't we just rescue the three little fellows, Zhang Yulin? It just so happens that they also have a certain understanding of radio, so you can ask their opinions." (End of this chapter)
