"The first thing you need to learn is Maxwell's equations, which are the most commonly used equations for electromagnetic waves." When he heard that his father-in-law asked him to teach, Li Zhiqiang had no other way, the old man easily agreed, and now he had to agree, but under Qin Feng's suggestion, there was no need to wait, and he simply started teaching.

When Qin Laohan encouraged a few people in the village and was ready to make a fortune by relying on this way, Qin Feng also understood why his father was suddenly enthusiastic about this, it turned out that he was to bring more villagers to get rich together.

Of course, this is to be encouraged, when he came, Qin Feng also said that his father, he can't just run to a well-off family by himself, he has to take everyone with him, and now, his father really did it.

Today, it's the Chinese New Year's Eve.

The crackling firecrackers outside did not affect Li Zhiqiang, and now, they are not at home, and there are not too many people at home, you know, when they saw the TV in Qin's old man's house so clearly, it all depends on the antenna on it, they are indeed tempted, with the development of society, as more people get rich, everyone has begun to buy TVs, which has to have antennas, and the antennas sold on the market are expensive and of poor quality, not as good as this in Qin Laohan's house, so what, They all came over, and they were indeed tempted, but now, when they heard these formulas that Li Zhiqiang said, they all stared dryly.

In the classroom of the primary school in the village, Li Zhiqiang took chalk and wrote formulas back and forth on the blackboard made of cement, and wrote the entire blackboard with a sigh, but how can everyone understand this thing!

"We don't understand this." Finally, Qin Laohan spoke: "Or, why don't you tell me what this tadpole is for?" ”

He pointed to an integral symbol on it, which is obviously the knowledge that will only be learned in college, and now, how can it make sense to talk to these people who have not gone to school!

At this moment, the door was pushed open, Gu Tingting and Qin Feng came over with the little tiger head to see the situation, originally only said that it was time to go back to eat dumplings at noon for the first half of the day, but now, looking at the symbols on the blackboard, Gu Tingting suddenly understood.

"Are you talking about college physics?" Gu Tingting asked.

Qin Xue didn't come, although she took Li Zhiqiang home, but after all, she was not married, and in the village, she took this very seriously, so during this time, Qin Xue lived in a relative's house, so that the two lived separately and saved gossip, while Li Zhiqiang came here every day to teach everyone, and Qin Xue cooked at home or something, with her mother.

Anyway, when I was in the unit, we were together every day, and in the past few days at home, let Li Zhiqiang hurry up and behave.

Gu Tingting looked at the blackboard and knew that Li Zhiqiang had taken the wrong path, and sure enough, this guy was a nerd.

"yes, is there a problem?" Li Zhiqiang asked.

"It's a big problem, if you talk like this, talk about it for three years, they won't do it." Gu Tingting said: "You tell them directly, how to make this antenna, what is the size, isn't this okay?" ”

"But, I know what it is, and I know why it is." Li Zhiqiang said: "If you can only do it, once you encounter a problem, they don't know how to modify it, to be exact, if you want to make an antenna, you have to know the wavelength data of the electromagnetic wave of the nearby transmitter, it is best to let the center of every two here, just fall on the voltage zero point of the induction signal, they not only want to sell the antenna here, but also sell it to the whole country, if you don't know these, how to do it?" ”

Nerd, really nerd! Gu Tingting was also speechless, I really don't know how Qin Xue fell in love with this guy, didn't you play the piano to the cow?

"You don't have to think about this, you now, just teach your father's antenna how to make it, teach everyone, their antennas are sold all over the country, it's still early, wait until this year's New Year, they sell it here for a year, and when you come back at the end of the year, you will calculate the size of other places for them, isn't it?"

After speaking, Gu Tingting made a look, so Qin Feng consciously moved the aluminum wires up.

"Let's all say, practice brings true knowledge, now, let's start practicing, come, Zhiqiang, you come up, teach everyone how to assemble it hand in hand, strive to assemble it in the afternoon, install it before the evening, tonight, many people are still waiting to watch the Spring Festival party!"

In the mountain village, a few years ago, the old man Qin's house had the first TV, which has become a big news in the whole village, and later, one after another, some families have children who go out to work, and when they come back, they have also bought back TVs, and now there are more than a dozen TVs in the whole village.

Although I bought the cheapest black-and-white TV, the size is still mainly 14 inches, but after all, it is also a TV, now, everyone is looking forward to watching the party, every day I listen to what Maxwell is talking about here in the clouds, we know who this name is so tongue-twisting.

Fortunately, Li Zhiqiang did not object, although he took such a shortcut, he was very dissatisfied, and he had to be down-to-earth in his studies, but if it ended so quickly, he would be able to go back quickly, after all, he didn't take a few days of annual leave, especially the test flight of the 1471 radar, which was a very important project.

Now, everyone followed up, listening to his introduction, how long is the size, which is in the front, which is in the back, how much spacing and so on, especially two of them are carpenters, and they are faster than Li Zhiqiang, and they will be done quickly.

"In this way, we can install it, pay attention, the wrapped signal cable, it is better to do shielding." Before Li Zhiqiang's words were finished, everyone had already walked away with the antenna.

Fortunately, the old man Qin has a car, drove to the county to purchase, before the closure of the year ago, he actually bought these materials, and now, this first batch is the test product, and when the effect is tested, everyone has mastered the essentials of production, and after the year, you can officially start it!

Li Zhiqiang looked at these people with a strange expression on his face, I haven't finished speaking, why are you all leaving?

"Let's go, let's go too, go back to eat dumplings, and we have to paste couplets." Qin Feng pulled Li Zhiqiang and came out as well.

In the village, crackling firecrackers sounded all around, and there was a smell of gunpowder in the air.
