In the Mansion of the Duke of Yi, in the courtyard of Tingtao, Yuwen Wen is playing games with his children, and he rarely has time to have children, so he has to try his best to attract the attention of the little ones and let them get close to "Aya". Pen, fun, pavilion www. biquge。 info

In order to avoid the defeat of his mother, Yu Wenwen did not let Yu Chi Chifan and others be present, but he did not plan to shake the prestige of being Aye, just to avoid his children from sticking to A-Niang too squeamish.

There was a pot of limes on the table, of course, the lemons were not ripe at this time, and Yu Wenwen didn't plan to eat them.

His eldest son, Brother Que, was holding a lemon and rubbing it vigorously with both hands, his little face was flushed, and he could see that he was exerting force; The second thorn took something from a small plate on the side and pricked it on the lemon handed by his brother.

A copper and zinc sheet with round holes at one end and one at the other end, Thorn Lang tied one on each lemon, and then handed the tied lemon to his sister.

Yuwen Eying and her sister Huannu used thin copper wires to connect the copper and zinc sheets on each lemon, and the zinc sheet of the first lemon was connected to the copper sheet of the second lemon.

According to the later generations, this is called "tandem", and what Yu Wenwen teaches his children to do now is fruit batteries.

In the sixth century, in the era of the Northern and Southern Dynasties, would it attract heavenly thunder and blast him into powder because of the violation of the laws of the plane?

The conscience of heaven and earth, the principle of the fruit battery is very simple, and it is easy to implement, if there is no lemon, apples and pears can be, it is nothing more than metal zinc is somewhat advanced, but it is also possible to replace it with iron sheets.

The little ones worked together, and the twenty fruit batteries were quickly "connected", and Yu Wenwen instructed Brother Que to connect a knife switch, and then let the thorn lang connect an electric bell.

Yu Wenwen couldn't make a light bulb no matter how bad he was, so the fruit battery performance in the fun science experiment couldn't use the light bulb to let the children have a direct cognition, so he made a simple electric bell as a substitute for the light bulb.

Is the principle of an electric bell complicated? It is not complicated and can be achieved with electromagnets and simple contact circuits.

A thin piece of iron with a bell hanging from the end, touching the wire to the right and an electromagnet to the left, the two are very close but not touching, this is a simple electric bell.

Circuit connection: one pole of the battery, a switch, an electromagnet, a thin iron sheet with a bell, the other pole of the battery, a circuit that is too simple to be simple, with a copper wire coated with tung oil as a wire, and a knife switch to control the circuit.

After the electromagnet is energized, the iron sheet is sucked over, but at the same time, the iron sheet is out of contact with the right wire, which causes the circuit to be disconnected, and the electromagnet fails if there is no electricity.

The electromagnet loses its magnetic force, the iron sheet returns to its original shape to the right, contacts the wire again, the circuit is turned on, the electromagnet takes effect and then sucks the iron sheet over, and the result is that the power is cut off and the magnetic force is lost again.

The iron piece moved back and forth, and the bell at the end was shaken and rang, a very simple principle, the only thing needed was electricity, and the power generated by twenty lemon batteries was enough.

The principle is very simple, but it startles the little guys, the older Yuwen Eying is fine, Brother Que and Thorn Lang are scared, and the slave directly has red eyes and cries.

Yu Wenwen picked up his little daughter and coaxed him, and after Brother Que and Thorn Lang experienced the initial fright, they played with interest, closed the switch of the switch, and watched the iron piece shake back and forth, and the little ones felt more and more interesting.

"Aye, what's going on?"

"Is there a youkai in the lemon?"

"There are youkai? Where's the monster! Aye, I'm afraid!! ”

The room was very lively, the little ones chattered and asked non-stop, Yu Wenwen probably explained, of course, he couldn't use the knowledge of electricity in later generations, he could only use metaphysics.

After the lemon is kneaded, it is filled with acid (electrolyte), and after inserting copper and zinc bars, it forms the yin and yang poles, copper is yang, zinc is yin, and then many lemons are "connected" with copper wires, so you can draw out the power of the wilderness... The power of yin and yang.

After playing with the lemon battery, Yuwen Wen began to tell the story again, although the mouth was dry, but the children listened to it with relish, sitting around Aya, and asking some whimsical questions from time to time.

Yuwenwen's sense of presence in the mansion is divided into two extremes: strong and weak, and for female dependents, his sense of presence is very strong; But for most people, Lord Lang often "goes out day and returns at night", and it is basically impossible to meet him in the mansion during the day.

This is nothing, just like modern society, most grassroots employees may not have met the chairman of the company in person, which does not hinder the normal operation of the company, Yuwenwen only needs to "will", so it doesn't matter about the sense of existence.

But not for children, his sense of existence is low, and he has no authority to educate children.

The son does not teach, the father's fault, his eldest son and second son are now about five years old, and they are in the first stage of the bear child, and if they don't discipline well, they will sooner or later upgrade to the "second order of the bear child", and it will be too late to correct it at that time.

How to teach?

A man who can't even see a shadow on weekdays, it is said that I am Aya, and it is rare to see each other, either that this is not allowed, or that the thing is not done right, and he roars when he disagrees, and scolds people so much that he is bloody.

After moving your mouth and hands, pulling your ears, beating your palms, spanking and whipping, you are so brutal, I have the wrong birth!

Yuwen Wen compared his heart to his heart, and thought from his son's point of view, if he Aya was this kind of person, his heart would have been screwed up a long time ago, and now he will endure it when he is young, and wait until one day...

The best example is Yuwen Yong and Yu Wenyun father and son, Emperor Wu of Zhou Yuwen Yong is wise and martial, but his tutor failed, and his son's character is worse than the other, he knows that the prince Yuwen Yun is not successful, but the other sons are even more unsuccessful, and they have no change if they want to.

Will this kid lose his country after he ascends the throne? It's possible, so I want to leave loyal ministers, capable ministers, and King Qi to assist him.

As a result, Yu Wenyun, who pretended to be a child and finally survived, immediately revealed his true nature after succeeding to the throne, and the loyal ministers, capable ministers and virtuous kings left by the first emperor were all killed, and they were all killed, and they got rid of it after just over two years, and the country changed color.

What's the use of Lao Tzu's ability, the foundation that he has worked so hard to build, and the son who is not a product will be lost in an instant.

So, teaching is naturally to teach, but first there must be a father-son relationship, otherwise sooner or later he will become an enemy, Yu Wenwen knows the importance of family education, but he is not an expert in preschool education, so he can only follow how his father of that era treats him.

Playing with his children, getting closer to the relationship, and blindly putting on the high-pressure posture of a strict father, the children will definitely go to extremes, or become a black-bellied acting school, and when the old man is old and can't hold it down, he will strongly rebound and settle accounts after the autumn.

Either he becomes a submissive wretch, has no backbone, and is extremely in love with his mother, commonly known as "Ma Bao", or is manipulated by his mother, or he is manipulated by a strong daughter-in-law or concubine.

Two examples abound in history, all of them are cheating fathers, Yu Wenwen doesn't want to be cheated by his son, so he has to work hard now to educate the next generation.

The parent-child activities continued until the sun set, Yu Wenwen asked the servants to clean up and bring the meal, and after eating dinner with the children, he began to busy himself with his own affairs after the little ones "went back to their own homes and found their own mothers".

The lemon had been cleaned up, but the simple electric bell was still there, and Yu Wenwen took a wooden bucket from a cabinet in the room and put it in front of the bookcase.

The wooden barrel has a lid, and two small holes are exposed on the lid, Yuwenwen inserts a copper bar and a zinc bar into it, submerges it in the saturated salt water in the barrel, and connects the two wires of the electric bell to the holes at the end of the metal bar.

Listening attentively, I didn't hear any signs of thunder in the sky above the mansion, and it was unlikely that something would happen in the sky, Yuwen Wen closed the switch of the gate, and the rapid bell rang immediately.

Fruit batteries? Copper-zinc galvanic batteries are powerful! (To be continued.) )
