"Ahem... That's to be vigilant. Zhao Hongjun whispered.

Li Yiming nodded: "Well, it's sauce purple, if the music is catchy and good, it's easy to get on when you sing it, people will be brainwashed, and your thoughts will follow the lyrics, which is based on science." ”

"Is it science? Which scientist said that?"

Zhao Hongjun took off his cigarette, feeling a little emotional and a little puzzled, I read a little and was easily moved by science, but you didn't lie to me, right?

"Does a scientist matter? Scientists are not necessarily right. Think for yourself, does music affect emotions, don't you have to use brain cells to remember everything in the lyrics?

If you don't have enough brains, you don't put good things, so that's how people become bad.

Because half of our people are animals, and the other half are social, and every seven years, more than half of the cells in the whole body may be replaced, which is called the seven-year itch, which is also a scientific conclusion.

So, no matter how good the mind is, it's easy to avalanche, and know why snow is easy to collapse? Because it's loose and soft, like ice, it's hard!

Therefore, each of us must be self-disciplined, constantly reflect, criticize and self-criticize, and use the system to manage ......."

"Ah......" Zhao Hongjun listened blankly, just remembering these words, I should record this child's words, and I will play it directly to him when Chen Changqing calls!

Before leaving, Chen Changqing told him to ask more questions, and then turned around and told him.

Zhao Hongjun looked out of the door, the two waiters had already held their notebooks, and they usually had to make records in meetings, which may have been a show at that time, but now, it must be serious.

Fortunately, Li Yiming didn't see anything, and finally picked up a box: "This one seems to be empty at the end." ”

"Oh?" Zhao Hongjun was surprised, "how do you know." ”

"Look at the thickness of this tape, and the length of the song on it, the song on this side is relatively short. ”

"How do you know the length of the song, it's not written on it. Zhao Hongjun asked strangely.

"I've heard these songs. ”

"Well, it's a little free, are you going to record something long?"

"Three minutes and fifty-eight seconds, but half and two minutes are enough. ”

"Oh... Huh?"

Watching Li Yiming pick up the harmonica from the table, Zhao Hongjun looked at him: "Or... Eat first?"

"If you eat grease in your mouth, you'll get dirty. Li Yiming carefully picked up the harmonica and tried a few notes.

Zhao Hongjun's ears pricked up suddenly, this was not the afternoon when he heard the music, it turned out that the child blew it.

"I'll fast forward it! This is a bit of a bad reverse, it's easy to roll. Zhao Hongjun said, saying that he wanted to operate.

"No, you turn it over and fast forward on side A, it's going to be faster. It is at the tail end of the B side. Then turn it over again. Li Yiming said.

Zhao Hongjun was stunned for a moment, this kid doesn't know how to use a three-purpose machine, but he actually knows this, and he has never tried it like this.

Li Yiming stretched out his hand to operate it himself, and he understood the use of these buttons at a glance just now. And he watched Zhao Hongjun dangling around with a cigarette awkwardly.

"How do you know?" Zhao Hongjun really couldn't help it, looking at Li Yiming leaning over and looking at Ka Gaili, his expression was the same as when he first got this thing.

But I didn't understand it at all, and this young man, who didn't seem to understand, seemed to understand it very well.

"Because this AB side is not the two sides of this tape, it is single-layered," Li Yiming took the tape and showed it to the two of them, patiently explaining, "This is a film tape made of plastic, called a baseband." There is a layer of metal magnetic powder on it, half of the A side and half of the B side, which is actually a single layer, like this. ”

"Eggs?" Zhao Hongjun couldn't hear clearly.

"It's not the egg, it's the base. Tape, the base of the base, the belt of the belt, it can do a lot of things, audio tape, video tape, computer tape and instrument tape, there may be a product called pressure tape......"

Zhao Hongjun asked very carefully: "This is the audio tape, I know the tape, I know the computer, it also uses this tape, what is the instrument tape, and what is the pressure tape?"

"Computers also use this belt now, which is used to store things, but all that is stored is data, just like a box, and the instrument belt may be the same, the code pressure belt..."Li Yiming thought for a while, "It's probably the kind of tape that stores small movies." ”

Zhao Hongjun hurriedly remembered it in his heart, and he could use it when he bragged in the future, this kid knows too much, erudite!

Li Yiming ignored the surprised expression of the adult, half-squatted and looked into the three-purpose machine, and pointed to the machine: "This is an application of the principle of electromagnetic induction, electromagnetic induction was discovered by the scientist Faraday, there are many generators, telegraphs and telephones, these are its application products in life."

You see, there's a magnet here, the current of the circuit changes, the strength of the magnet also changes, and then the belt passes through here under the drive of the runner, and the magnet affects those small magnetic powders to form different magnetic patterns, and then it records the data. It can be music, it can be other data, and movies can also be ......"

"What you said, it's all science, right?" Zhao Hongjun asked in a low voice. The two waiters on the side of the door didn't dare to speak for a long time, and stood with wide eyes and watched the little hairy child talking about science.

"It's science, too!"

Zhao Hongjun swallowed: "What grade is this taught?"

Li Yiming was slightly stunned, a little angry: "Does this have anything to do with the grade grade? This should be common sense, don't you buy this thing and don't want to know how it works inside? Why can it be broadcast and recorded?"

I'm not curious at all, so how do we copy other people's good products? Then we have to exchange our own good things for foreign exchange, and then buy these things that come down the assembly line, this is a waste of what you didn't expect?"

Zhao Hongjun turned his head to look at Li Jianguo with great difficulty, feeling that his father was still easy to speak, and asked in a low voice: "Shanzhai, does it mean to rob?"

He has read the Water Margin, and the chairman said that the best thing in this book is rebellion, of course, Lu Xun doesn't like to kill people indiscriminately, especially Tie Han Li.

"Imitation... Learn what it means to do it yourself. Li Jianguo had already heard his son say this, and he was very proud to popularize science with Zhao Hongjun.

It's almost what Ghost Li meant, Zhao Hongjun felt that he understood!

He sighed slightly, his eyes swept away, and the two waiters outside the door hurriedly recorded in the small book, the cottage is imitation, we have to work hard to copy other people's good things.
