Chapter 898: The Prelude to the Beginning of ScienceThe Law of Inertia(1/3)

Li Mengxi offered the heaviest reward so far. Anyone who could solve one of the dozen or so questions he gave would be directly awarded a thousand-man general and be directly rewarded with a huge amount of money, food, wine and meat.

For everyone in the army, whether they are scholars or ordinary people, scholars do not value money, food, wine, and food, but they value official career. They must value the rewards of thousands of generals. Those craftsmen and ordinary soldiers who have no big pursuits are enthusiastic about wine, meat, money, and food.

To everyone, to put it bluntly, as long as you can solve one problem, you will jump directly into the dragon's door.

To do scientific experiments, you need to have tools, and whether they are small balls, various slopes, or tracks, it is not easy for ordinary people to get them.

In order to help the formation of the research atmosphere, Li Mengxi stopped all tasks in the carpentry camp and devoted himself to making slopes, slide rails and other objects.

With the craftsman's production capacity at full capacity, more than 500 sets of test tools were produced in three days.

This is just physical preparation.

Li Mengxi also posted the question everywhere so that everyone could see it, and he also had people publicize it everywhere to more fully mobilize the initiative of the people.

——

My younger brother, Xiao Zhuan, has been obsessed with playing small balls these days.

He plays with small balls and wooden blocks all day long. He can play with simple small balls and wooden blocks for a whole day without getting bored.

Li Mengxi watched his brother play quietly.

The younger brother was playing this game over and over again - he put the ball on a wooden board, then pulled it hard from the left to see the ball go to the right, and then pulled it again from the right to see the ball go left

run.

This little guy discovered a strange pattern. The ball was disobedient. Wherever the board moved, he had to do the opposite.

When Little Brick repeated the game a hundred times or more, he took the board and ran over.

"Brother, look." Xiao Bian put the ball on the board. He pulled the board to the left and the ball rolled to the right.

Place the ball again, pull the board to the left, and the ball rolls in the opposite direction again.

"Brother, look, he has to go wherever I run, right?" Xiao Zhuan asked seriously.

Li Mengxi had been watching for a long time. He just thought that Xiao Bian was playing randomly. When his younger brother asked, Li Mengxi was quite surprised.

This is... inertia.

Inertia is... Li Mengxi thought about it in his mind.

Li Mengxi can understand the inertia theorem. It is not difficult to explain it to Xiao Zhuan. It is not difficult to explain it directly to Xiao Zhuan.

But, how to guide it? Li Mengxi thought about it.

After a long time, he thought of a good way.

He said nothing and decided to just play with his brother.

Li Mengxi and his brother came to the same side of the short table. He made a strange move. He moved his hand in front of his brother's eyes and compared with the height of the short table.

Not good, too low.

Li Mengxi went out and moved a few bricks, and padded the low table until it was about the same height as his younger brother's eye level.

Then, he smiled and said to his younger brother, "Little Brick, let's continue playing."

"Okay!" The younger brother nodded.

It was Li Mengxi who pulled the wooden board. He placed the wooden board directly in front of his younger brother's eyes. He also deliberately placed the ball in front of his younger brother's eyes, and then pulled the wooden board violently.

You can see that from the side, from the height where the line of sight is level with the ball, the ball does not seem to be moving.

Xiao Bian must have seen this strange thing, and he scratched his head.

Li Mengxi continued to repeat this.

He placed the ball again and again, and twitched the board to the left or right again and again. The same phenomenon was repeated many times - why did the ball not move? There was always a momentary pause.

"Brother, I want to play too!" The younger brother reached out for the wooden board.

Li Mengxi stopped and handed the investigation back to Xiao Brick.

Under Li Mengxi's subtle guidance, Xiao Zhuan has successfully noticed even stranger phenomena.

Compared with the strange phenomenon that the ball rolls backwards when the board is pulled to the left, the ball does not move when the board is pulled. This phenomenon is several times weirder.

Xiao Brick was concentrating on playing. He knelt on the ground and lay down with his eyes on the board. He held the short table with one hand and grabbed the board with the other, staring straight at the little brick placed on the board.

ball.

He suddenly pulled the board apart. The board moved and the ball seemed to be frozen there. It stayed motionless for a long moment.

"Huh?" Xiao Zhuan exclaimed in surprise. He turned back to look at Li Mengxi, with a look of surprise on his face, "Brother, why doesn't it move?"

Li Mengxi rubbed his brother's little head and asked with a smile, "Didn't you just say that he would run backwards?"

Xiao Bian thought about it seriously, then scratched his head, "No, brother, he didn't run back, he just didn't move, look."

Xiao Zhuan thought that Li Mengxi didn't understand, so he showed it to Li Mengxi again.

Li Mengxi looked at it seriously.

After his brother finished the demonstration, he looked very puzzled, "Hey, why is this? Why doesn't it want to move? Is this little ball lazy and doesn't want to move? Let's find something else to see, okay?"

"

"Okay!" The younger brother nodded vigorously.

The reason why Li Mengxi wants to guide his brother to find other things is to extend from individual cases to more things. If he finds that the same is true for a large number of things, then he can conclude that this is common among all things in the world.

The most universal and fundamental law.

Afterwards, Li Mengxi and his brother went to find random things, including dirt, leaves, grass, sand, and Xiao Bian, who didn't know what to think, even picked up a hair.

Li Mengxi pinched the hair that Xiao Zhuan had messed up. He looked at the hair and then at Xiao Zhuan, feeling somewhat speechless.

This thing is light and small, how can I observe it?

Although Li Mengxi knew that inertia must exist in any kind of thing, the observation effects of different things are very different.

Li Mengxi was helping his brother quietly.

In view of the fact that the friction force of soil, garbage, leaves, grass and stems is a bit high, the test results will not be very good. Li Mengxi went out for a while, and he brought a half-sided paint-patterned colorful shield. The reason why it was half-sided was that it had just been cut off.

.

The paint shield is very smooth and much easier to use than ordinary wooden boards.

Li Mengxi and his brother did many tests on half of the paint shield, and they observed everything carefully.

During every test, before pulling the shield, Li Mengxi reminded him, "Xiao Brick, look at this time, he can't move."

Xiao Zhuan got very close and looked at it with wide eyes.

Finally, after testing everything, everything did not want to move without exception.

No matter whether you pull the shield to the left or right, the things on the shield always want to stay where they are.

Li Mengxi smiled and asked his brother, "Xiao Brick, why are they not moving?"

Xiao Zhuan nodded firmly and said in a sweet voice, "It's because they don't want to move."

Li Mengxi glanced at the messy things and thought of something that was not here.

He asked, "Well, Xiao Bian. Do you think if we find a date and put it on it, will he move?"

Xiao Zhuan's eyes lit up, "Where are the dates? Brother, I want to eat dates."

"Uh." Li Mengxi was stuck for a moment.

Only then did Li Mengxi realize that his brother was still a child after all.

Li Mengxi spent a while to comfort his brother, and he promised that he would get dates for him to eat tomorrow.

"That little brick, let's take a brick and put it on the shield..."

"Isn't that me?" Xiao Bian opened his eyes wide and pointed at himself in confusion, "I'm not Brick?"

Li Mengxi succeeded, covered his forehead and chuckled.

I don’t know what my parents thought, giving my younger brother such a rubbish name as “Brick”, ugh.

"Then, if you put... put an egg on it and let's pull up the shield, do you think the egg will run away at first?"

"No." Xiao Bian gestured with his hands, one hand as an egg and the other as a shield. "It won't move, it will stop here."

"Then, if we put a stick, will he move?"

"Won't."

"How about some money?"

"Won't."

"How about a dragon ball?"

"Won't."

Little Brick may not understand the induction method, but he tried a bunch of things and didn't want to move anything. He took it for granted that everything was the same. He, his little brain, had succeeded.

Apply the truth to everything.
To be continued...
