Qin Enze saw that a lot of people had gathered below, and suddenly opened his mouth and laughed:

"Listen to everything from my Kyushu Academy of Sciences!"

Below, the riotous crowd suddenly fell silent. Li Zhen roared with tears in his eyes: "Don't talk, don't make noise, listen to Enze." ”

When everyone was quiet, Qin Enze suddenly took out a folded cloth from a large package at his feet. This is a canvas used for small fishing boats, the canvas is not thick, but it is very strong and has a good seal.

Qin Enze held the canvas in his hand and shouted, "Everyone listen to me." I'm going to prove the wind resistance now, and if I jump from here and I'm still alive, then we can work backwards to prove that humans can definitely take to the skies. If I jump from here and die, then we still have a long way to go, and we still have a lot of mysteries to solve. ”

When Li Zhen heard this, his anger became smoky, and he pointed at Qin Enze above and shouted, "Enze, you come down for me." You don't need to prove it, if you really want to prove the power of wind resistance, we can prove it by tying a stone to the cloth. ”

Qin Enze shouted: "It's not intuitive! ”

"Intuitive!"

"It's not intuitive, I don't think it's intuitive. I can only feel the intuitive experience when I personally jump from here. ”

Qin Enze is crazy, he is a madman!

Li Zhen looked at that hideous face, and was so angry that he almost vomited blood: "Qin Enze, you are crazy!" ”

Qin Enze shouted: "The students from the School of Mathematics and the School of Physics have all given me wide eyes to see clearly." I pinched the stopwatch and gave me the calculations, based on my feet off the ground. Not a single minute or second is allowed to be missed, and calculate how long it will take me to land. Don't let Lao Tzu's efforts go to waste. ”

Everyone below was stunned and didn't know what to do.

Li Zhen slapped his thigh fiercely and shouted: "Record! ”

"Quick, record!"

"Stopwatch ready."

"Quick, get the stopwatch."

"Quickly keep your eyes open and look closely, observe his state in the air, observe the movement of the canvas, and guess the strength and direction of the wind resistance."

"Hurry up and prepare."

“……”

The Kyushu Institute of Physics was in an uproar, and everyone knew that this Qin Enze was the king who was determined to jump down from above. You can't persuade you at all, you can't stop it at all.

This disfigured and blind ugly monster has proven his madness and stubbornness countless times. Even Li Zhen didn't have any way to take him.

This time, he also has to use his life to prove the existence of wind resistance. Some understand why Qin Enze jumped down, because of aerodynamics, everyone just understands the concept and knows the data. But there is no intuitive feeling at all.

Although other phenomena can prove the validity of these phenomena, everyone still does not know the bottom in their hearts.

Qin Enze obviously didn't know the bottom either, he didn't know if human beings could use tools to break through gravity. Qin Enze believes that only if he jumps from here and is still alive, can he let everyone have real feelings in their hearts.

Li Zhen naturally understood Qin Enze's feelings, so he could only follow Qin Enze and let everyone hurry up to record it.

A minute later, everyone from the entire Kyushu Academy of Sciences came. Faculty of Chemistry, Faculty of Mathematics, Faculty of Physics. School security, sanitation, staff.

All of them are here. Standing densely downstairs.

The students of the School of Physics and the School of Mathematics all sat nervously on the ground, each holding a notebook and a pen in their hands, and sitting upright. Ready to start calculating the moment Qin Enze jumped down.

And many people in the physics institute have a pen in their right hand and a stopwatch in their left hand.

The math faculty nervously started to test the data on their notebooks.

"The roof is 32 meters above the ground, so ......"

"No, it's 32 meters from the height. But Qin Enze will have a jumping process, when his height will actually become at least 32.2 meters above the ground. ”

"Qin Enze's weight ...... How much does it weigh? ”

"Estimate, the height is 170, the figure is even, and the visual weight is about 130 pounds."

"Predicting a normal free fall, the time to land is between 3.6 seconds and 4.5 seconds."

"How did you come up with the answer in 3-4 seconds?"

"Estimates, of course. Where do I know the specific data? ”

“……”

Qin Enze was still preparing, and the people from the School of Mathematics had already listed the data in their notebooks, and they were already arguing about the accuracy of the data's advance prediction.

The people in the Physics Academy had a different style of painting, and everyone looked at Qin Enze nervously. Unlike the School of Mathematics, where everyone talks to themselves, no one communicates.

"Qin Enze weighs more than 100 catties, if the area of this canvas is more than 6 square meters, according to the principle of aerodynamics, he should be able to land safely, right?"

"If you compare this whole air to water, the world to a swimming pool. Then the wind resistance that you have everywhere is converted into the resistance of water. Can all this be true? ”

"Alas, this dog thing, whether you are dead or alive, you have become famous in one fell swoop."

"If Enze proves the support of the wind resistance, it is enough for a person to land safely. That would be the only person in the history of the world, and the first person to personally prove wind resistance. ”

"In terms of fluid mechanics, how do I think Qin Enze is more auspicious this time?"

“……”

The school staff gathered in groups of three or five, talking with a look of horror in their eyes: "This group of teenagers is really crazy." ”

"It's self-defeating. Jumping down from the tenth floor, he will definitely die unless he is an immortal. ”

"It's going to kill you. I can't imagine how he can not die anyway? ”

"Well, get ready, we'll collect the corpse later."

"This Qin Enze is really, every time he comes to the cafeteria to eat, he is very polite and quiet. Why is it so crazy? ”

"Don't kill yourself."

“……”

Li Zhen stood under a tree, shaking his legs uneasily, and looked at Qin Enze standing on the rooftop with fixed eyes. In fact, he didn't dare to guarantee what kind of fate Qin Enze would be.

There are so many uncertainties here.

Although he jumped down with the canvas, the theory may be true. But it's hard to say. Is it possible that the wind resistance was too great in the middle and he got rid of it? What if his own force was too strong, but not enough to grasp the canvas? In case Qin Enze weighs too much, the wind resistance borne by the canvas area is too much less than Qin Enze's weight?

No matter which one of them is, it is enough to make Qin Enze die.

On the rooftop, Qin Enze suddenly shook the canvas open.

A large canvas, about two and a half quilts combined. Qin Enze didn't jump off the building impulsively, he had already gone through the plan in his mind before.

"If the wind is too strong, in order to prevent my free fall from going too fast, and my strength can't grip the canvas. So I need to tie the four corners of the square canvas to my hands and feet. ”

"The canvas area is 6.5 square meters, the canvas weighs 10 pounds, and my weight is 136 pounds, which is 146 pounds of power free fall. The canvas had to bear double the weight to keep me safe. ”

"Ugh."

"I regret it a little."

Qin Enze smiled bitterly while tying the four corners of the canvas to his limbs.

When the canvas was tied, a rudimentary parachute prototype appeared.

At this point, he is more like a magical creature in nature - a flying squirrel.

Qin Enze stood on the edge of the rooftop, looking down, he couldn't help but feel weak in his legs and pale in his face when he was afraid of heights.

With trembling hands, he took out his cigarette gun and took three puffs hard, choking on tears.

"Ahh

Sticking the cigarette gun into his trouser belt, Qin Enze spit out a puff of smoke and screamed violently.

The whole person left the edge of the roof and threw himself forward. Below is thirty meters in the air.

A leap of faith.

"Jumped!"

"Timer starts!"

"Quick!"

"Jumped!"

“……”

In an instant, everything below was boiling.

Li Zhen's body suddenly stiffened, and his eyes widened and stared at the person who fell down from the sky.
