"Da Lang, dad is gone, take good care of your mother." "Dead, he's still a nursing baby, he can understand what you say, what to take care of his mother, it's his mother who takes care of him."

Changle hugged Da Lang and glanced at Yang Heng fiercely and said, "Come, Da Lang, tell Daddy, go home early and buy delicious food for Da Lang." This scene has been staged like this for the past few days, Yang Heng has now become an office worker, every morning after eating, he goes to catch the train, and then gets off the train after dark, and lives a life of not seeing the sun at both ends, how can he not see the sun at both ends, that is, when he gets up in the morning, he gets on the train, the sun has not yet risen, and when he comes back at night, the sun has set.

However, although the time to leave home and go home is fixed, the place where Yang Heng goes is not fixed, sometimes it is the academy, sometimes it is the train manufacturing factory, and even a few other factories, in short, there are some things waiting for him to solve, this, how to say it, that is, these technical projects of his do not have a formal theoretical system, Yang Heng has begun to think in his mind, when, some theoretical systems should be completed, otherwise, these technologies will not progress, but will retreat, That's not what he wanted to see.

However, Yang Heng does not regret doing this, if he doesn't do this, maybe he will give some people no bones left, if you say, the emergence of the same technology will attract the attention of many people, the appearance of ten kinds of technology will cause people's desire to get the psychology, but the emergence of a hundred kinds of technology, that will make people afraid, the same technology, Li Er may pay attention to some, ten kinds of technology. Li Er might also want to kill Yang Heng. Get such a technique. But when it comes to a hundred techniques, Li Er will definitely protect Yang Heng.

If, coupled with Yang Heng's own physical strength, then it will definitely let all conspiracies go aside.

Therefore, if Yang Heng analyzes a technology from the beginning, it will be like electricity. For example, starting with the friction to generate electricity, and then studying lightning, step by step, it is estimated that in ten years, Yang Heng will not be able to finish the research, and he will not be able to bring out a qualified apprentice, although if he brings out an apprentice. That must be an elite, but Yang Heng can wait. How to calculate the money consumed, and what to do with the peeping in all aspects.

…………

"Ah Lang, there's a message from the hot air balloon ahead, they want us to develop a technology that doesn't communicate through wires, I don't know, can we develop it?"

This is a question raised by the technical department after Yang Heng arrived at the academy, because, at this time, Yang Heng has no direct contact with some of the following aspects, if they have any requirements, they will first go through the technical department of the academy, if the technical department can't come up with a plan, the technical department will ask Yang Heng questions again.

The technical department of the academy is a problem-solving department specially established by Yang Heng before, it concentrates all the technical forces in the academy, forming such a department, usually, after a minister with a few scribes in the office, if someone comes to raise a problem, he will quickly concentrate the corresponding technical personnel to tackle key problems, if the research fails, and then provide the suggestions to Yang Heng, and Yang Heng will immediately give this project to the corresponding department for special research, it is such a procedure.

Although sometimes after passing through Yang Heng's hands, some of them will return, but this is different, after Yang Heng's hands, there will be some practical suggestions, and the direction of their research will be set.

"Cheng, it seems that this project is going to be officially put on the agenda, you first organize a technical research team to come out, organize it, let them report to the mountains, these research personnel first choose a few people who have some foundation in electromagnetism, this, there must be some auxiliary facilities to tackle key problems together."

Wireless communication, this is not an independent project, including electromagnetism, electronic technology, and even some component manufacturing, and at this time, Yang Heng needs to manufacture vacuum electron tubes the most, so he put this department on the side of the glass research institute, the first thing to do is to manufacture vacuum electron tubes, he also wants to make transistors first, but as a metal research, there has not been much progress, that is, the zinc used to make dry batteries has not yet been developed.

When he thought of dry batteries, Yang Heng felt that he should not pay attention to the research work of metals, but this radio must use dry batteries, even if there are no dry batteries, it can be made into batteries.

"Boss, we're so stupid that we haven't been able to develop the zinc you need." The person in charge of metal research and development said with some embarrassment, you know, Yang Heng has given them a lot of funds, and for so long, they haven't even developed any zinc.

"You show me your results during this time." Yang Heng said noncommittally, this matter is not urgent, however, Yang Heng will not comfort them anymore at this time, and will put some pressure on them to let them use their brains more.

"This, isn't this the zinc I want, how can you say that it hasn't been developed?" When they took out some metal plates, Yang Heng exclaimed, he found that there were all kinds of metal plates, one of which was zinc plates, suddenly, Yang Heng blushed a little, he didn't see zinc before, he really couldn't understand what this zinc looked like, as a result, the result was already out.

"Alang, this is zinc, we developed it a year ago." It's really.

"Okay, okay, it's all blame on me, I didn't make it clear to you, you copied down the production process of this zinc, and also, make another part of the zinc, I have an urgent need, this piece, I'll take half of it."

"Bang bang." Yang Heng slapped his face, "Come, everyone, let go of the work in your hands first, and I'll give you an experiment." As he spoke, Yang Heng asked his subordinates to bring a few apples, and he took a knife to peel off a piece of the apple, and then put it on the table.

"Boss, you're giving us apples." There are people who have a good relationship with Yang Heng, and they joked with Yang Heng, "Eat apples, then start with you first, come, you take these two threads." Yang Heng took out some iron sheets and copper sheets connected with copper wires from the box placed by the people on the side, naturally, this iron sheet is everyone's opinion, in fact, this is a zinc sheet, Yang Heng put on gloves, and slowly a copper sheet, a zinc sheet was inserted into the apple, when Yang Heng inserted the last zinc sheet.

"How does it feel?" "It feels good, there is a feeling of numbness, is this electricity?" "I'll try, I'll try." When they heard this, everyone was a little eager to try, you know, these people have a great desire for technology, they have been studying the technology that Yang Heng taught them before, when they studied at the beginning, they felt mysterious, but the more they studied, the more powerful they felt this thing, so the more they studied, the more fascinating it became.

"Well, really, owner, what does this mean, can this apple be able to generate electricity?" "This, you need to study it yourself, some vegetables and fruits, you can all test it, and also, I will draw two drawings for you, you first develop these two things, materials, go to the metal research institute to ask for them, and I have marked these materials for you, if they are not marked, you can develop them yourself."

Yang Heng also knows that dry batteries can not be developed soon, first of all, what chemicals are in it, he doesn't understand very well, people want to test themselves, and lead and zinc batteries, will be manufactured first, and so on has a prototype, Yang Heng will formulate specific specifications, this is simple, zinc has, lead has long been available, sulfuric acid, hydrochloric acid are also available, and the only thing that can't be grasped is the concentration, specific gravity, this, slow test is, or, Yang Heng let them make a concentration to detect acid, The specific gravity tool is also not very troublesome.

"Boss, what's this called?" "This, I call it a battery, that is, a container for electricity, more than a capacitor for charging, you are developing it first, and if there is any progress, I will give you the next production plan."

"You see, I said there should be a lot of containers for electricity, don't you believe it, but now there is." (To be continued......)
