"What, you haven't listened to the radio yet? Wu Laoqi, Wu Laoqi, you are really old in this thought, you don't even know about broadcasting? This is the most fashionable novelty in today's society, as the old saying goes, you can't stop eating the marrow! ”

"Really...... Is it really that amazing? ”

"Our brothers grew up peeing and mud, can this still lie to you? To tell you the truth, listening to the radio can not only listen to the news, but also listen to the drama, don't look at the small box, there is a big world hidden in it, you know what it means? ”

"What does that mean?"

It means that radio can reform the family and slowly shape it into a new type of family, Professor Cheng said in yesterday's broadcast, the emergence of radio has made the house successful and the old market the same center of information exchange, change ...... Hey, that's what it means anyway, you just know it's important. ”

"Oh, I'll go, it's only been a few days since I went back to my hometown, and I feel like the world has changed a lot since I came back."

"Isn't it, especially the ...... in there. What is the female announcer's name, the voice is like a yellow bird, I heard that the bones in my ears are crispy, why do you say that Professor Cheng is so good, this novel technology can be studied, originally I was not very interested in 'Mr. Sai',

It's okay to say that 'Mr. Sai' doesn't like me, anyway, I haven't been able to love new technology, and I feel that it's too far away from us, but Professor Cheng's broadcast is really different, and this is really letting us know how powerful 'Mr. Sai' is. ”

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

"That's what I said, if I want to listen to it, go straight to Central Park, there are two hours of radio time at noon, enough for you to listen to it for a while, but it's better to be at home outside after all, this time I'm going to go over and study the radio, and then I'll go home and build one, and if the effect is good, I'll install it for my eldest niece."

"Then I'll thank you for being an uncle for my daughter......"

The two of them were talking in front of them, and Cheng Nuo listened with relish in the back.

It's not that he likes to listen to the wall roots in the back, it's just that these two old brothers talk about this with too loud voices, coupled with slightly exaggerated body movements, and even be able to appear in mime dramas of this era, it's really hard not to attract the attention of passers-by.

But even so, Cheng Nuo was not embarrassed to continue listening to it for too long, and after understanding a little bit of the content of the broadcast, he quickly overtook the two of them and walked in front of him.

Things have developed to this day, although he has tried his best to raise the power of broadcasting, but after really understanding it, Cheng Nuo found that he still underestimated the transmission effect of broadcasting.

Everywhere you go, there are people talking about this thing, especially the content of the storytelling broadcast inside, the topic is unprecedentedly high, and in a trance, there is a feeling of talking about yesterday's cartoon head to head before elementary school class in the previous life.

Although the journey home is not short, it is all radio content, and I even saw some parents sitting on their children around their necks and pulling their wives to Central Park, enjoying themselves.

However, if you think about it carefully, in the previous life, Cheng Nuo had never experienced the "four major pieces" era of the first generation of "three turns and one ring", that is, radios, bicycles, sewing machines, and watches, where could you appreciate the importance of radio and supporting radios.

"Yali Mountain is big!"

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

It was also a coincidence, just as Cheng Nuo finished cleaning up his mood and was about to push the door home, as soon as his hand was pasted, the door automatically opened.

It's not that the door is automatically sensing, but an acquaintance just came out of it.

Cheng ...... Professor Cheng? You're back? The visitor was pleasantly surprised.

Cheng Nuo looked kind and gave a big hug to the visitor: "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. ”

Ye Qisun was a little restrained: "It's almost time, the ferry ticket has been bought, and it will leave in a few days, I thought that I couldn't see Professor Cheng before leaving, but I didn't expect you to come back." ”

Cheng Nuo sighed with some emotion: "Yes, I'm back, I still have to come back to do some things, it's more reassuring to do it myself." ”

However, looking at Ye Qisun Xing's hurried appearance, Cheng Nuo was concerned again: "What's the matter, this time I must not be just visiting, is it a problem in mathematics, or do you have some experience in physics?" ”

Ye Qisun shook his head: "Aren't they?" ”

Cheng Nuo was curious: "What is that?" ”

Looking at the hesitation on Ye Qisun's face, Cheng Nuo smiled again, pushed the door and pointed inside, and said, "Let's go, it's not convenient for me to say here, let's go into the courtyard and close the door." ”

Ye Qisun breathed a sigh of relief when he saw this, 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 burnt briquettes, lit the stove in the house, and sat on the kettle, and the room slowly warmed up.

Originally, this living Ye Qisun was going to rush to do it, but unfortunately he didn't fight for Cheng Nuo, but it was uncomfortable to sit and sit, and he was embarrassed 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, to do radio business."

"Oh? Are you 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 about it. Cheng Nuo was very happy to hear the news, and after patting the ashes on his hands, he specially instructed: "Just make it a hobby, don't treat it as a main business." ”

"You've told me this before, do what you're good at and like." Ye Qisun's face was a little darker, but after looking at his satchel again, he cheered up and said: "Professor Cheng, in fact, I came here this time because I was entrusted by Tsinghua students, who wrote a lot of letters to you, and I brought them all this time." ”

After saying this, Ye Qisun opened the schoolbag, carried the bottom and shook it a few times, and dozens of letters immediately came out of Lima and formed a miniature hill.

Cheng Nuo glanced at the other party deeply, Ye Qisun also felt a little embarrassed, and hurriedly added: "The classmates really admire you very much, and they all want to have some learning exchanges with you, all with good intentions." ”

"Haha, I naturally understand this, but I didn't expect there to be so many, but I looked down on myself." Cheng Nuo said with a smile.

But to be honest, Cheng Nuo was still very happy to see these letters, and picked up one casually and read it carefully.

"The competition in the twentieth century is to use intelligence, not physical strength, the concept of education in the past has long been backward, it cannot be limited to students reading and reading in schools, there is a radio broadcast by Professor Cheng, the object of education is instantly expanded to the whole people, the content of education is all life, and the place of education is the whole society......"

Continue to look at one more, and it is also similar in it:

"Our country is culturally backward, the people's wisdom is not developed, there are many illiterates, and transportation is very blocked, so the shortcomings of disseminating knowledge through printed matter are particularly obvious in our country, and the implementation of broadcasting education is particularly necessary ......in our country."

Looking down, in addition to admiration, these students even put forward some genius-like ideas, expressing their willingness to go to the radio station to be temporary hosts, passer-by A popularizing meteorological information, passer-by B talking about mathematics, and passer-by Ding studying science and culture...... If you do the math, two hours is not enough for these students.

"Your students' ideas are very good, these details even I didn't take into account, but let's speak first, the most important condition for an announcer is the language, an excellent announcer must not only be able to speak fluent Chinese, tune the announcer's language broadcasting art and comprehensive quality, not as simple as you think." Cheng Nuo said with a smile.

Regarding this question, Ye Qisun seemed to have been prepared, patted his chest and said: "Of course I know this, for example, the commentary told some time ago, no matter how wonderful the words on the original paper are, they can't compare to the impassioned words in the announcer's mouth, and the hard news has become a vivid story, which is particularly good." ”

After the call, Cheng Nuo was surprised to find that the radio thing also has an unusual popularity among the student group, but if you think about it carefully, the younger you are, the more curious you are about novelties, and the faster you accept it.

"But I didn't send someone to install the ore radio at Tsinghua School, where did you hear the broadcast?" After reading a few similar letters one after another, Cheng Nuo put down the letter for the time being, and asked curiously: "Could it be that you assembled it yourself?" ”

Ye Qisun nodded fiercely: "Yes, after our classmates knew about the broadcast, they knew the principle through your article, and they assembled one by themselves, although the listening effect is not as good as that of the Academy of Sciences, but it can also be listened to, basically a few students can assemble one together." ”

Cheng Nuo couldn't help laughing and said: "No wonder there is such a sentence 'Peking University is old, the teacher is poor, only Tsinghua University can be accommodating', you Tsinghua students are still relatively rich, and some parts are still not cheap." ”

Ye Qisun didn't refute this, and laughed after pondering these words a few times.

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

"Come in, the door is not closed."

"Then I'm in." Lifting the door curtain, it was Jiang Jiang Zuo who came into view, and after seeing Jiang Jiang Zuo sitting in the room, he was surprised: "Xiao Ye hasn't left yet, I thought you couldn't wait for the dean, so you left just now." ”

Cheng Nuo took the initiative to explain for him: "I was going to leave, but I just happened to meet me at the door, have other things been arranged, what are you looking for me to do this time......

Before he finished asking, Cheng Nuo knew the purpose of Jiang Jiang Zuo's coming.

It's not because he has mind-reading skills, but the stack of letters Jiang Zuo is holding is too conspicuous, and the person sitting next to him is Ye Qisun, so Cheng Nuo can almost judge that the other party is also here to send the letter.

When I asked, it was exactly the same as I guessed.

"These of mine are different from Xiaoye's, although they are all letters, but the sources are more complicated, and they are closer to our grassroots compatriots." Jiang Jiang Zuo patted the stack of letters and introduced: "This is still a part of it, if you want to see it, the 'big army' can be pulled over 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 trouble other comrades. ”

Although Cheng Nuo was already looking forward to these letters, after opening and reading them, he still felt extremely admired, and sure enough, wisdom came from the people.

It turned out that the content of the letter was a friend named Zhujun, who was very itchy after seeing the "National" magazine about the production method of ore radio, and hearing the story of a friend who had returned from a business trip to Beijing about the magic of broadcasting.

After the successful trial restoration, he found a more convenient way and shared the method and process of making his own ore radio, hoping that more people will be able to use the ore radio.

I bought ore from a drugstore, and went to a foreign company to buy an earpiece, plus a ready-made paper tube, a paper cutter, and copper wire, and spent only a few yuan, so I made a radio out of these small items, and even attached a special structural drawing.

"Okay, whether we studied chemistry or mechanics before, to put it bluntly, the majority of our compatriots couldn't participate in it, this friend's letter inspired me, we might as well do 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?"

"Tech competition? This is good, although there are not many of our compatriots who have gone to school at the moment, but the structure of the ore radio is not complicated, and the threshold for getting started is very low, I believe that there are definitely many people who are willing to participate in this activity. Jiang Jiang Zuo's 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 hurriedly said: "There should be no limit to the participants in this competition, right?" ”

Cheng Nuo pretended to be serious and said: "The science and technology competition is not a child's play, of course, it must be taken seriously, and the participants should be screened." ”

Ye Qisun said anxiously: "Huh? Are there any restrictions on who can participate? Can we, the students, participate? ”

Seeing that the other party was serious, Cheng Nuo hurriedly said: "Of course you can participate, our limited object of participation is Chinese, and only Chinese can participate." ”

Jiang Jiang Zuo agreed: "The purpose of the competition is also to let more people enjoy the changes that science and technology have on their lives, especially the current radio broadcasting, which will inevitably be an important way to enrich the spiritual life of our Chinese in the future. ”

Thinking about the fact that in the past life, many people just held the radio to understand the outside world, and even learned English through the radio, the practical meaning behind it is very large.

And Cheng Nuo also has the intention to pave the way before the official launch of the "National" broadcast, so that it can go more smoothly later.

After discussing the competition process and rewards, Jiang Jiangzuo suddenly asked, "But how should this judge be chosen?" If it's all us, as athletes and referees, I'm afraid it won't be easy to convince the public. ”

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