Chapter 255 Wisdom Limits! The eighth official live broadcast (middle)

"Tear!"

Accompanied by the ear-piercing sound of tape tearing, the five-meter-long red seal was separated from the box, and was thrown into the air by Chen Yu at an altitude of 3,400 meters.

In order to allow the audience to see clearly, he turned sideways, stood on the left side of the courier box, and slowly opened the left box cover facing the camera, revealing the light blue cylinder inside.

Then, Chen Yu walked to the right side and lifted the right box cover. The full picture of the product was finally shown in the eyes of Chen Yu and more than 20 million viewers...

[Nimma! barrel? 】

[This gun barrel is not very smart, Yazi. 】

[It's a bit like Dongfeng Express! 】

[It may be a nuclear bomb launch pad. 】

【Electromagnetic Gun Hammer! Summon Miss Cannon! 】

【Obviously a planetary engine...】

[UP Lord, no matter how awesome you are, do you dare to live broadcast in the Forbidden City on Monday? 】

"Um……"

Taking four or five steps back, Chen Yu carefully observed the shape of the blue cylinder, frowning in thought.

Like many spectators, just looking at the appearance, even if he was on the scene, he would not be able to recognize what it was.

"Come on, help."

Hooking hands at Xiao Taohong, the two completely separated the express box from the product.

"call……"

After throwing the box, Chen Yu manipulated the camera to observe the cylinder 360° up, down, left, and right, but he was still not sure of its true use.

"After the unboxing session, everyone should be like me, confused about what it is. From the portal, to the weather console, to the floating castle, the more future products, the more beyond our imagination. "

Reaching out, Chen Yu took a card from the bayonet on the right side of the cylinder: "But fortunately, with the help of the instruction manual, we 'ignorant' ancients can explore the mystery of the future."

With that said, Chen Yu skillfully activated the switch on the card, and carefully swipe to read it.

"What the hell?"

As soon as he saw the name of the product, Chen Yu couldn't help exclaiming, and quickly accelerated his reading speed. And as the understanding gradually deepened, the surprise was immediately shocking, and then turned from shock to admiration... He kept muttering to himself.

"magic……"

"It's so beautiful..."

"incredible……"

"Amazing!"

Since this card does not have the ability to project, only Chen Yu can see the content and description of the broadcast. The 20 million viewers in the live broadcast room can't stand it, but they can only wait anxiously, sending out barrages of urging.

After more than ten minutes of "cold silence", Chen Yu put down the card, looked at the camera in silence for a long time, and finally sighed: "It's amazing, it takes a capricious designer to create this product."

"Do you know what it is for?"

【you do not say! How the hell do we know? ! 】

【Made! The anchor definitely did it on purpose! 】

[The cameraman added rice to his shit today. 】

[This damn program effect! Don't play tricks! 】

[I don't know what you are talking about, I just came to see the female assistant. 】

[Look at the female assistant. Is it possible to have such a good discussion with just a big iron rod? TM a group of gays! 】

[I watched it in every live broadcast room, with a total of more than 20 million viewers! Don't you have to go to school and work? 】

Inserting the manual back into the bayonet, Chen Yu stroked the smooth surface of the cylinder a few times, sorted out his words for a while, and said, "It's hard to explain this product in a few sentences. Because it involves a lot of things related to astronomy, chemistry, physics, knowledge of aeronautics and spaceflight."

"That's right, this is an aerospace product. A product that no one would have imagined in 2020. All previous technologies, even if they can't be made in modern times, have scientists, novelists, or various cultures. It has been described in the works. There are also theoretical supports for various technologies.”

"But it." Chen Yu patted the cylinder: "It is blank in human history. At least, I haven't heard of anyone or any cultural work that has its shadow."

After a slight pause, Chen Yu straightened his back, recalling the knowledge he had learned in the past few weeks in his mind, and said loudly: "The unpacking session is over, and the next step is the introduction. I will try to introduce this product to you in as simple a language as possible. The magic and the absurd."

"First of all, there are currently only two ways for humans to enter space."

"First, rocket propulsion. Second, aviation aircraft. The latter also needs rocket propulsion. So strictly speaking, humans can only enter space by rocket propulsion."

"But due to the high cost of rocket propulsion, the scientific community has always wanted to find a more efficient method. The most famous and most feasible is the space elevator."

As he said that, Chen Yu stretched out a finger: "Then, in order to introduce the space elevator, we have to mention a character. Tsiolkovsky from Mao. The audience in the live broadcast room may not know this name. But he You must have heard of the title."

"He is honored as the father of aerospace!"

"That sentence: The earth is the cradle of mankind, but mankind will not stay in the cradle forever. It is also what this great god said."

"This deaf god was born in 1857, when there were no airplanes. But in that era, before human beings studied how to ascend to the sky, he began to study how to go to the sky, how to fly into space, and enter the universe."

"He saw that a punctured balloon would be blown by the airflow, understood the reaction force, and immediately created the principle of jet rockets, and completed the formulas and calculations of the system. One of the formulas is also named after him, called Ciolko Fowski's formula."

"V=V0×Ln(m0/m1)."

"The derivation of this rocket speed formula is very easy, and it can be calculated with a little calculus. I will not delay on such simple problems."

【ah! It's a boss! my eyes! 】

【show! 】

[I feel the ridicule from the wise man. 】

【Mom asked me why I jumped into the toilet to watch the video...】

[A liberal arts student said that your grammar is wrong. (Smile)】

Righting the mask, Chen Yu continued: "According to the formula, if you want to go to the sky, the jet speed must be large, so the mass ratio of m0/m1 must also be large. m0 is the original mass of the rocket, and m1 is the remaining mass after jetting. Both The 'ratio' between is larger, what does it mean?"

【have no idea. 】

[I don't know +1. 】

[I can understand every sentence, but I can't understand it at all. 】

[I understand it all, but I don’t understand it at all...]

[Awesome, awesome...]

After a pause, Chen Yu smiled: "It means that the mass of the fuel is greater. Therefore, most of the mass of the rocket is fuel. It has not changed until now. This is also the main reason for the high cost of space operations, which is too wasteful. "

"After completing the principle of jet rocket, this god went a step further, designated liquid fuel, and then created the principle of multi-stage rocket... Until he completed this series of great achievements, human beings didn't even know how to build airplanes."

"Some viewers may want to ask, what is his relationship with the Sky Elevator? Why should we focus on introducing him?"

"Because the space elevator was also proposed by this god, and completed all the theories and calculations, including the structural strength of the material, the height of the space elevator, the weight ratio, the balance point of 36,000 kilometers, etc. As long as the materials in it meet the standards, Human beings can follow the legacy of the father of spaceflight and directly create a space elevator."

"This is not a delusion! In 2019, Japan and China successively produced qualified materials, and the space elevator construction plan has already begun. At most 2050, the project will be fully launched, and everyone will definitely see it in their lifetime."

"but……"

Chen Yu reached out and patted the surface of the cylinder: "With this thing, the space elevator plan can be abandoned. It doesn't need 2050. With the current technology of human beings, there is a foundation for building this product."

"The only thing that limits its birth time is the brain hole of the scientific community."

"Its name is..."

"The earth sprays water!"
