"What's wrong with you?" Jiang Wanbai found that something was wrong with Tian Jinfeng, so she asked.

Tian Jinfeng was awakened and hurriedly looked sloppy, "I'm looking at the layout of this house, it's not the same as before." ”

Of course, the things in this are all according to Jiang Wanbai's preferences, "How can there be anything that remains unchanged in this world, people are like this, things are like this, even this house is not the original house of the family, how can this arrangement be the same." Jiang Wanbai said casually.

Tian Jinfeng suddenly realized, yes, she has been away from home for so many years, she herself doesn't know herself, how can her mother not change.

Especially at home, she suffered setbacks one after another, her mother is the pillar of the family, and she can't help it.

Thinking about it like this, Tian Jinfeng regretted even more that he was obsessed with ghosts at that time, and he cut off contact with his family because he was afraid of upsetting his in-laws when he was in the most difficult time at home.

Jiang Wanbai saw that Tian Jinfeng's face was changing, and thought that she had some kind of ghost idea, so she immediately said, "I'm going out soon, so I won't leave you." The meaning of sending off the guest in the tone is very obvious.

Tian Jinfeng didn't blame Jiang Wanbai for saying this, the suspicion was already there, how could it be so easy to eliminate, burying her plans in her heart, she said to Jiang Wanbai that if there was something, go to her, and got up and left the Tian family.

She walked on the front foot, and Jiang Wanbai let Tian Lao Er set up the ox cart and went straight to the county seat.

In the south of Pingyang County, in a quiet and elegant courtyard, Jiang Wanbai followed the servants who led the way all the way, and finally came to a garden.

The servant pointed to Master Lin in the garden and said, "My master is there, but he is now studying at the university, you must not disturb him, otherwise he will lose his temper, don't blame me for not reminding you." ”

When Jiang Wanbai heard this, she was a little anxious, she was burning her eyebrows here, "How long does it usually take for Bachelor Lin to study knowledge?" ”

"This is not necessarily, if the master understands it, it may be just a stick of incense, a cup of tea time, if the master can't figure it out, there is a study for half a day or even a day or two." After saying that, the servant continued, "You will wait here. ”

Waiting like this, when is it a head, Jiang Wanbai wanted to step forward immediately, but she was also afraid that she would really anger Bachelor Lin like this, last time Bachelor Lin only said that he owed her a favor, who knows how much this favor is, if she acts rashly, Bachelor Lin doesn't help her, where can she find a second person who can help her.

Enduring the anxiety in her heart, Jiang Wanbai nodded in agreement.

Seeing that Jiang Wanbai understood, the servant stood with Jiang Wanbai for a while, and then went to busy with his business, leaving Jiang Wanbai and Tian Lao Er standing there, like sitting on pins and needles.

In a flash, the time for a stick of incense passed, not to mention that Master Lin had finished his research, he didn't even move, as if he had settled down.

Jiang Wanbai clasped her hands and walked back and forth in circles, and in the end, she couldn't wait, so she came to Master Lin's side to see what he was studying.

There was a table in front of Master Lin, and on the table was a clay pot, in which there were two balls the size of a ping-pong ball, one of which seemed to be made of wood, floating on the water, with a smooth and round surface, as if it had been painted, and the other was iron, which sank to the bottom of the water.

Next to the crockpot, there is also a scale, I don't know what it is for.

Just when Jiang Wanbai was looking at these things, Master Lin suddenly moved, he picked up the wooden ball, put it on the scale, and muttered to himself: "When the wooden ball is put into the water, the weight of the water overflowing from the crockpot is the same as this wooden ball, but the weight of the overflowing water is much less than that of this ball."

Could it be that this is why the wooden balls can float on the surface of the water while the iron balls sink to the bottom? After Mr. Lin said this, he fell into deep thought again.

When Jiang Wanbai heard this, she was stunned, she didn't expect that Master Lin would say this, and he was infinitely close to the true meaning of buoyancy.

Buoyancy, first discovered on Earth by Archimedes, also used this discovery to identify whether a crown made of pure gold is doped with silver, equal to the gravitational force of an object, equal to the density of the liquid multiplied by the constant g multiplied by the volume of displacement.

Master Lin's current discovery is about the same as that of Archimedes, that the force experienced by an object in a liquid is equal to the mass of the liquid that is displaced, but in terms of calculation, because no one like Newton has discovered gravity, he is limited again.

"The wooden ball floats on the surface of the water, and the iron ball sinks to the bottom of the water, their situation is different, how can they be compared together." Knowing that Master Lin would definitely ignore her if he didn't solve this problem, Jiang Wanbai hesitated for a moment and then interjected.

"yes, how did I forget that." Master Lin didn't notice that someone next to him interjected, his two eyes stared at the two balls in a daze, and said with some surprise, "If only this iron ball could float on the water like a wooden ball......

Speaking of this, he himself felt that his thoughts were ridiculous, and denied: "How is it possible. ”

"You can't float on the water, but if you break it into a thin iron box, like a wooden boat, maybe you can?"

"It's impossible." Master Lin subconsciously retorted, "I've never heard of wooden boats, who has ever seen an iron boat." ”

"Just because you haven't seen it doesn't mean you don't have zài." In the present, the steel cruise ship is not running around, Jiang Wanbai has absolute confidence in what she said.

Master Lin finally noticed Jiang Wanbai's cunning, but he didn't blame her, but asked with some hesitation: "Have you seen it?" ”

"I ......" Jiang Wanbai really didn't dare to say that she had seen it.

When Mr. Lin saw Jiang Wanbai talking, he thought that she was stopped by him, what she said before was all nonsense, so he was a little angry, and said with an unhappy face: "Nonsense, this is the villain's doing." ”

With his attitude and tone, Jiang Wanbai couldn't bear it, "Whether I'm talking nonsense or not, I'll know later."

Bachelor Lin has studied through the past and the present, and I have a question now, I hope you can help me answer it. As we all know, this glutinous rice ball will sink to the bottom when it is first put into the pot, but after a while, it will float up, why is this? ”

"That's because the rice balls are cooked, no." Bachelor Lin's expression was solemn, and after a while, he said as if he had thought of something, "It's because the size of the rice balls has changed, and the same rice balls, when its size becomes bigger, it can float." ”

Speaking of this, Master Lin's eyes suddenly brightened, like a lit torch.

As soon as he fished out the iron ball from the jar, Master Lin shouted: "When you get bigger, you can float, the iron box, the iron box can float, it turns out that it is like this, it turns out that it is like this." After shouting twice, he suddenly danced with the iron ball hand as if he were crazy.

He made such a fuss, which naturally attracted a lot of domestic servants, and they asked Master Lin, "Master, what's wrong with you?" "On the one hand, I want to tie up Jiang Wanbai and Tian Lao Er, according to their ideas, there are just the two of them here, the master has become like this, he must have been harmed by them, and he can't let them go.

When they came over like this, Tian Lao Er was taken aback, "Mother......"

Jiang Wanbai also felt depressed, did she not do anything at all, and even if she did, she was also helping Master Lin, not only did they not appreciate her, but they even wanted to treat her like this, she was really going to die unjustly.

There was no way, she hurriedly shouted at Master Lin: "Master Lin, didn't you say last time, do you owe me a favor, I have something to ask you for help now, Master Lin, Master Lin ......"

Those family members didn't care what Jiang Wanbai said, they had to reach out to grab her, and seeing it, Jiang Wanbai was about to be caught, and at this moment, Master Lin's voice finally sounded like nectar.

"Stand down, who told you to come?" Master Lin's voice was gloomy and powerful, and there was indescribable anger in it.

The family members all withdrew their hands in disdain, wanting to explain to Master Lin, but they were interrupted by Master Lin, "Don't let me go down yet." ”

All the family members, look at me, I look at you, there are some monks who are two years old, and they don't know what's wrong with their master, but since the master said it, they can only do it, so they all retreat.

After they left, Master Lin came over and gave Jiang Wanbai a big gift when he bent over, "I have eyes but no beads, and I actually treat pearls as fish eyes, I really have lived most of my life in vain, wise man, please accept my worship." ”

Bachelor Lin called Jiang Wanbai a wise man, this is a great respect, there are many dynasties and generations, and those who can be called this title are full of calculations, and they are no more than two hands, if this is known by outsiders, they don't know how much jaw will drop.

Jiang Wanbai was also taken aback, she really didn't dare to take this title, where was she a wise person, she just took advantage of the times, and hurriedly supported Master Lin, she said, "Master Lin, what are you doing here?" I'm just talking about it casually. ”

“

Yes? Jiang Wanbai swore that what she said just now really didn't mean that, "I mean, what I just said was all my imagination, and I heard you talking there and guessing wildly." ”

Master Lin looked at Jiang Wanbai with an expression of disbelief on his face.

"Really, I don't even know why you're so happy in the end." Jiang Wanbai is planning to die and not admit it.

She can't do this kind of limelight thing, she has already returned all the knowledge of physics to the teacher, she only knows what it is, but she doesn't know why, if she really wants to pretend to it, sooner or later she will be exposed.

Seeing that Jiang Wanbai said so sincerely, Master Lin also hesitated a little, could it really be just a coincidence? But last time, last time, Jiang Wanbai solved his problem, two such a coincidental coincidence......

But looking at Jiang Wanbai's appearance, she is just an ordinary old lady from a peasant family, and there is no reason to know so many things.

Bachelor Lin thought about it there, but Jiang Wanbai was anxious, and said what she just said again, "Bachelor Lin, didn't you say last time, do you owe me a favor, I have something to ask you for help now, you see, can you help me." ”

"Do your best." Seeing that Jiang Wanbai was really anxious, Master Lin suppressed the question in his heart and asked what was going on with Jiang Wanbai.

Jiang Wanbai said that Liang Gaoyuan relied on the power of Qin Shangshu to forcibly marry a people's daughter, but he couldn't marry by force, and colluded with officials to threaten the Meng family with Dr. Meng as a servant, and finally, she said: "That Meng Guoer is only ten years old this year, how can she marry, ask Master Lin to call the shots." ”
