Although the circular square is not large, it is more than enough to accommodate more than two hundred and dozens of candidates.

In front of the four gates, it was as if getting up early in the morning, and the four hottest stalls in the lively morning market were surrounded and surrounded one by one.

Each stall has a completely different style -

Li Xiaotong of the East Gate is the most Buddhist, except for climbing the wall regularly to update the suction cup, she has nothing to do;

Simon is the most rock, everyone gets together high, like a singer concert scene!

The south gate is the most lively, the stall owners and customers fully interact, and they are very busy;

The north gate is the quietest, except for a very small number of people who have evolved the ability to sense magnetic fields like pigeons, they can detect the invisible coercion that is a little terrifying, in the eyes of most people, this is a door, a road, go if you pass, and retreat if you can't go;

Xu Tianmeng of the South Gate is looking forward to Ye Chao coming to his side, after all, it is his sister's thing, and he has to be responsible for the checks.

It's a pity that although Ye Chao is interested, he doesn't have the consciousness that his uncle's favorability needs to be brushed.

The hot gas deflects the light, which is very useful to others, and it is almost meaningless to him who can overlook the whole audience at any time.

As for the hot gas offset trajectory......

"This is the picture taken by Wanzhen's high-speed high-definition camera every second, you can take a look. The stone that is often hollow is clearly skewed, not because of the visual effect of the light agitation, but because of the real skew. ”

"As we just said at the East Gate, the so-called air pressure is the force exerted by air molecules on the surface of an object by Brownian motion."

"Normally, the higher the temperature, the more intense the molecular movement and the stronger the pressure; However, when the temperature is high, it will also cause mutual repulsion and make the air thinner...... That's how hot air balloons fly. ”

"So in general, it is very difficult to quickly change the trajectory of a macroscopic object by relying on air molecules."

"I guess Xu Tianye's ability to accelerate air molecules while still not reducing or even increasing their density; And it can be quickly and accurately controlled, from which direction to apply pressure, which direction to withdraw pressure......"

"Only in this way, according to the Bernoulli equation, can the deflection trajectory in the picture be derived."

"I talked about Bernoulli's equation in fluid mechanics before, and if there are still people who don't understand, you can watch the replay on the split screen."

"In short, if you want to pass the level, you must first have a high density of projectiles!"

"The higher the density, the worse the air deflection effect will be at the same volume."

"The density of the stone is 2.6~2.7, which is too floating; If you change to 7.8 for iron, it will be much better, if you have 19.3 for gold, 21.5 for platinum, or more than 20 or even more than 30 for the idea tanning, the speed only needs to reach more than 100 meters per second, and there is a great chance of hitting the target directly. ”

"In addition, it is better to have the projectile rotate, which increases stability and interferes with the stable deflection of air molecules."

didn't get started in person at all, just passed in front of the third uncle's door, cracked the tricks of other people, and then Ye Chao patted his ass and came to Ximen.

At the same time, many anchor reporters in the square coincidentally gave Ye Chao the most pictures.

I can't help it, I said I would be smashed.

There is no harm without contrast. In the past, there was no Cui Swamp, and their embarrassment was embarrassing, and everyone could bear it, but now there is a comparison, as if thirty is like a wolf and forty is like a tiger, but the husband can't bear it.

The picture is given to Ye Chao, they don't show their heads themselves, so they don't have to take the blame.

There are 200,000 beasts in Jiangcheng, and they really won't lose it.

Although Ye Chao's class is also dry, it is dry goods, not dry ice that has nothing to dissolve, and is more watery than water.

Those who can understand are fascinated, and those who don't understand are not aware of it, and even faintly have ideas, after the college entrance examination, they must supervise their children's homework, those liberal arts homework!

Take a look at Jiangcheng's college entrance examination this year, the dog food double star, the god goose hero, more than 100 points ahead of others, are all full marks in liberal arts.

From the third to the tenth, there are also two or three liberal arts subjects that are close to full scores.

Liberal arts are a great advantage! And it doesn't seem to affect the exercise of the main subject much......

Some far-sighted parents, not even waiting for the end of the college entrance examination, have been secretly collecting all the explanation videos of Ye Chao so far, ready to study well for their children.

The atmosphere of thinking about it every day can be regarded as being completely driven by Ye Chao and Xu Tiange!

Before coming to the West Gate, Ye Chao, as always, carefully analyzed the spectral characteristics of a wave of other speakers.

In the end, it was concluded that although the nameless dragon set fire weapon was a speaker, the destructive power did not depend on the volume of the voice, but on the resonance and resonance skills similar to Tang Lin.

Resonate with the heart sound, make people's blood flow accelerate, and consciousness unconsciously falls into chaos;

Resonates with the skin and makes people feel as if it is tangible;

The resonance itself is the cochlea of the resonator, which will directly amplify the sound, compress the vestibule of the inner ear, and produce a dizzy and vomiting effect similar to motion sickness;

If you want to resist, you must first get rid of the natural high state with the music, and control the changes in your heartbeat, the tightness of your skin, the sharpness of your cochlear sensations, and so on in your restlessness.

It's like a spy movie, the enemy is tracking your radio frequency, and you'd better keep changing the frequency and shoot a different place to avoid being chased.

This seems incredible to modern people, for the new human beings of natural disasters, it belongs to some high-end cultivation, but it is also a basic operation, one star and two stars may not be mastered, and most of the three stars will.

Those that don't work can only be covered with things.

This in turn involves the effects of refraction, reflection, diffraction, and diffusion of sound waves at different frequencies.

In short, after an analysis of the sound field image that ordinary people don't understand at all, Ye Chao gave the worst sound effect based on the position of the three speakers and the reflection and refraction between them and the walls and floors.

Placing your head exactly at these points, combined with the correct ear covering posture, can reduce the resonance effect by more than half.

As for him like him, who can build a sound-absorbing chamber with materials at will, he can naturally live as well as he wants, without any pressure!

While watching his explanation, everyone watched the clearance videos of some lucky people on other screens, and really discovered the mystery of those points.

Those candidates who passed the test, although they did not have Ye Chao's knowledge reserves, they could rely on the five senses instinct of the state to accurately find these points.

They successfully cleared the customs, which also confirmed Ye Chao's reasoning in disguise, and attracted more people's attention to this side.

The number of fans in Mr. Ye's lecture hall continues to increase......

After finishing the explanation of the West Gate, Ye Chao came to the North Gate in anticipation.

At this moment, 200,000 people are watching.

"For Mr. Ye, this should be the most difficult one, right?"
