Although he saw it with his own eyes, he couldn't believe it.

"No way, it's fake! It's definitely fake! ”

"No, no, there's something wrong with this barrel!"

Li Su smiled slightly, and then said to Fan Tong:

"Fan Yushi, if you think there is a problem with the barrel, you can do another experiment."

"However, I can tell you very clearly that no matter how many times you do it, the result will only be exactly the same!"

"And guys, if you still can't believe it, you can go home and do your own experiments. Look at the results, it's not exactly the same. ”

Fan Tong ignored Li Su's sarcasm, and sure enough, he chose a wooden barrel and conducted an experiment again.

And this time, without exception, the barrel broke again.

This is enough to prove that only a very thin bamboo pole is needed to form a terrifying water pressure.

This is enough to prove that water pressure is only related to water depth.

Li Su looked at the depressed Fan Tong and sneered: "Fan Yushi, now it is proved that this king is right and you are wrong." ”

"If you want to gamble and lose, do you want to resign now?"

Fan Tong's face was dazed, and he muttered to himself: "Impossible, this is impossible, how is this possible?" ”

After a while, he suddenly said, "By the way, by the way, you still have a ridiculous place!" ”

"You said that if you ignore buoyancy, the speed and time of an object are only related to altitude and gravitational acceleration, right?"

Li Su nodded and said, "That's right, in fact, it's only related to height." Because the acceleration due to gravity is fixed. ”

Hearing Li Su's words, Fan Tong immediately laughed wildly: "Listen, listen, how ridiculous is this kind of talk?" ”

"Your Highness, let me ask you, two stones of different sizes land from the same height, and the time they land is the same?"

Li Su couldn't help but say: "If you ignore the almost negligible friction, yes, their landing time is almost the same!" ”

Fan Tong couldn't help but laugh again: "Listen, listen, how wild? How ridiculous? ”

"It's something that three-year-olds know, haha! You can all testify for me! ”

Li Su looked around and found that some of the officials at the scene had disdainful expressions on their faces, and some were shocked.

There are also some with melancholy faces, and the main representative is Li Shimin.

Li Su only thought it was very interesting, and couldn't help but say to Fan Tong: "Since Master Fan is so sure, why don't you do an experiment with the public?" ”

Fan Tong sneered: "Okay, which imperial history will make His Royal Highness the King of Shu completely dead!" ”

After that, Li Su ran directly to the flowers and trees next to him and picked out two stones, one large and one small.

These two stones, the big one is the size of a bowl, and the small one is only the size of an egg, and the difference in volume is very large.

Fan Tong held the stone, put his hands flat on his chest, and said to Li Su with a sneer: "Your Highness, you are optimistic. ”

"Let's take a good look at how the big rock landed first."

After that, Fan Tong confidently let go.

The many imperial histories around him, as well as the officials who impeached Li Su, also showed the same confident expression on their faces.

Only a few people, including Li Shimin, showed a worried look on their faces.

Syllable!

But the next moment, the situation that arose was a slap in the face.

Two stones, almost making a sound.

It landed almost at the same time.

Of course, it's not very clear because it's too close to the ground.

But the difference in the time when the two stones hit the ground is definitely not big.

At least it's a lot less than they thought.

At the scene, except for Li Su, almost everyone's expressions fell into a stupor.

Today, the subversion brought to them is too great.

If the attempt at water depth is wrong, is the common sense of the stone also wrong?

But how is this possible?

Isn't that completely unreasonable?

Besides, why didn't they find out about it in the past?

Fan Tong, who was sluggish, quickly reacted.

He hurriedly picked up two stones and held them high above his head.

He couldn't wait to say: "Two stones, it is definitely impossible to land at the same time, just now the height is too low to see." ”

"If you don't believe me, I'll look at it again!"

Fan Tong lifted the two stones to almost the same height above his head, and then let go.

Syllable!

But as a result, the same slap in the face.

Two stones, still falling almost in no particular order.

"Impossible, impossible! When pigs fly! ”

"It's because it's too short, if it's taller, you can definitely see it!"

"Wait a minute, wait a minute, wait until I throw it down on the high platform, and I will definitely see it."

With that, Fan Tong took two stones and hurriedly climbed to the top of the palace.

The top is about two feet above the ground.

From this distance, there is no excuse left.

Fan Tong's hands trembled and stretched out, ready to let go.

Below, dozens of Tang monarchs and ministers also held their breath and watched nervously.

Although it has been confirmed on two occasions just now, it has been confirmed that the two stones fell at the agreed height, almost simultaneously.

It has nothing to do with the size of the stone.

But this experiment completely subverted their cognition.

Just like in later generations, when I made my debut for many years, I still announced that I was still a woman - can you believe it?

In their hearts, like Fan Tong, they also believe that it is because of their low height.

They felt that as long as the height was high enough, the time for the two stones to fall to the ground would not be very close.

And the current height, it is enough.

Therefore, the results of this experiment are the most correct.

On the high platform, Fan Tong let go tremblingly.

Two stones with a large difference in size began to fall from a great height.

The two stones fell very quickly.

But because it is high enough, the falling trajectory can still be clearly captured.

In mid-air, two stones, indistinguishable from Xuanyuan, indistinguishable from each other.

Syllable!

In the end, it also landed almost at the same time.

This scene made everyone present except Li Su have a deep-rooted cognition in their hearts for many years, and it collapsed suddenly.

It turns out that what they think is absurd and heretical theories is correct!

And the way of argument is actually so simple.

It's as simple as picking up two stones and throwing them away.

But from childhood to adulthood, most of their lives, they have never doubted this, never argued.

Today, all of them, so to speak, have been taught a lesson by the King of Shu.

The eyes of everyone looking at Li Su, the king of Shu, were full of complexity.

On the high platform, Fan Tong walked down in despair.

Li Su looked at him with a smile and asked, "Fan Yushi, this time, did you lose?" ”

Fan Tong was stunned and was silent for a long time.

After a while, Fan Tong suddenly said frantically: "Even if these two things are yours and me, I am wrong. ”

"But in arithmetic, what kind of numbers do you use to defile the ancestral writing?"
