The books in the science and technology tower are different from the textbooks we usually use when studying. Although the books in the science and technology tower appear like books, there are actually many forms and methods of transferring knowledge in them.
For example, in the simplest way, we calculate the area of a triangle. Using the formula, we all know that the formula for the area of a triangle is half of the base multiplied by the height. As for how this formula is derived, many of us have not thought about this issue carefully.
In the science and technology tower, if someone comes to teach you how to calculate the area of a triangle, he will continuously change a triangle in the form of dynamic animation, allowing you to have an intuitive understanding. As long as the base is long
Just like the height, the area of a triangle remains the same no matter how it changes.
The books in the science and technology tower impart knowledge not only with text, but also with language, pictures, and videos, as well as derivation processes, combined with the practicality of this knowledge point.
When you start learning, you may learn a lot more content, but the impression will be more profound, and the knowledge and depth will be expanded. You can also cultivate a reverse derivation thinking, and combine it with reality to apply what you have learned.
At this time, the book on anti-gravity technology that Qin Yi was looking at was like this. It was directly presented in Qin Yi's mind in the form of videos, pictures, texts, etc., so that he could better learn and understand the anti-gravity in it.
principle.
Before understanding anti-gravity, we must first understand what gravity is?
The force an object experiences due to the earth's attraction is called gravity. According to Newton's law of universal gravitation, objects with mass have gravity. The greater the mass, the greater the gravity. The gravity on the earth is the earth's gravity.
Of course, this is just our understanding of gravity based on Newton's law of universal gravitation. In fact, Newton's law of universal gravitation has many natural phenomena that it cannot explain.
The most important one is the contradiction between the accelerated expansion of the universe and the law of gravity. According to the traditional Big Bang theory, the universe is constantly expanding because of the Big Bang. The expansion of the universe will gradually increase due to the gravitational force between galaxies.
slow down.
But in 1998, scientists discovered through observations that the expansion of the universe is not decelerating, but accelerating. This is actually inferred through the red shift between galaxies.
This phenomenon cannot be explained by Newton's law of universal gravitation, so scientists put forward the viewpoint of dark matter and dark energy, believing that dark matter and dark energy exist widely and account for most of the total mass of the universe.
In addition to the phenomenon of accelerating expansion of the universe that cannot be explained clearly, there is also a phenomenon of gravity anomaly on the earth. The weight of the same object at the same altitude, the same dimension, and different places is different. This is the phenomenon of weight anomaly.
.
In addition, there will be some strange places on the earth. For example, there is a section of river in Taiwan that will show the wonder of water flowing to high places; the gravity is abnormally strong in some places on the earth; the trees in some areas will tilt uniformly.
People can't stand up straight and so on.
In fact, we only know about universal gravitation and gravity, but if we think deeply about it, what exactly is gravity?
Just like light, after we understand it deeply, we know that it is photon, and we know that the propagation form of light is in the form of light wave.
In the same way, what exactly is gravity? What things is it made of? And in what form does it spread or move?
Of course, scientists on earth have been thinking and researching this aspect for a long time. Scientists have put forward the idea of "electric field force". In the center of the earth, at a pressure of 3.6 million atmospheric pressure and a high temperature of 6000k, the "solid core" of the earth is
It is definitely not a solid substance at our normal temperature. According to the laws of physics, it can be inferred that it is a huge electropositive body.
Bohr's theory and quantum mechanics show that electrons moving around the nucleus will jump to the outer layer after absorbing energy (heating), and will be emitted (hot electron emission) when the energy is large enough; the principle of nuclear fusion reaction proves that atoms are subjected to huge forces.
At high temperatures and pressures, most electrons outside the nucleus will escape.
Under the huge pressure and high temperature of the earth's core, the escaped electrons will form a negative electric layer in the mantle under the influence of the gravitational force of the macroscopic positive electric field of the earth's core and the Ampere force in the magnetic field, forming an internal and external polar capacitor with the positive electric field of the earth's core.
Due to the offset of the electric potential between the internal and external electric fields and the large insulating layer of the "tens of kilometers thick crust", the earth's surface generally exhibits neutral characteristics. The gravity of the negative electric field of the mantle layer will attract the entire crust and all materials on the surface, forming gravity.
However, this view was not recognized by scientists because there were many different explanations. At this time, in Qin Yi's mind, all the knowledge about gravity was revealed.
It is very simple to explain gravity using the content in the book. Mass is the basic attribute of matter. Matter with mass will have a mass field.
The stable state of an object must be the state of existence when the center of mass and the mass field of the object are in a symmetrical state. Once asymmetry occurs between them, the object must show a state of motion.
This is a natural phenomenon caused by the basic properties of matter and has nothing to do with the physical, chemical and energy characteristics of the object. When two objects exist at the same time, there must be an asymmetry between the center of mass of each object and the mass field of the other object.
state, therefore, they will 'naturally' exhibit a state of motion, which is free fall motion.
"I see. I only knew about gravity before, but I never thought about the nature of gravity."
When he saw this, Qin Yi suddenly realized. When he first learned about gravity, he only remembered that Newton was hit on the head by an apple. He only remembered the formula of gravity, but he did not think deeply about the nature of gravity.
"The movement of light is light waves, the movement of sound is sound waves, and the movement of electromagnetism is electromagnetic waves. I didn't expect that the movement of gravity is also a wave. Gravity waves. Einstein is really awesome. He has clearly understood it a long time ago.
The nature of gravitational motion.”
After seeing the movement and transmission of gravity, Qin Yi couldn't help but worship Einstein again. A good person is a good person, and he recognized the movement and transmission of gravity very early.
After understanding gravity clearly, the knowledge about anti-gravity quickly appeared in Qin Yi's mind.
Engels pointed out that "attraction and repulsion are as inseparable as positive and negative" and "the material theory based only on attraction is wrong, inadequate and one-sided."
Gravity and repulsion are contradictory and unified. They coexist in matter and between objects at the same time. This is the basic law of the structure of matter and should also be the basic law of the structure of macroscopic stars.
Microscopic particles have the motion of negative electrons revolving around positive electric nuclei and rotation. The revolutions and rotations of stars between macroscopic stars should also be electromagnetic interactions. The physical properties of macroscopic and microscopic matter should be the same.
Antigravity is actually a force opposite to gravity.
"It turns out that gravity is the most direct manifestation in front of us, while anti-gravity has a hidden feeling. The moon did not fall. In addition to being far away from the earth, a more important reason is because of anti-gravity.
The existence of, or the existence of repulsive force.”
Soon, Qin Yi felt a sudden enlightenment. According to the content in the book, gravity and anti-gravity are like yang and yin, one is bright and the other is dark. We feel gravity most of the time.
The reason why we don't feel the existence of anti-gravity is because anti-gravity is manifested in the "dark place".
"The principle of anti-gravity technology is to make full use of the anti-gravity hiding in the 'dark place' to achieve flight away from the gravity of the earth."
Seeing this, Qin Yi couldn't help laughing. This anti-gravity technology seems to be very simple. The principle is simple and easy to understand. Find the anti-gravity hiding in the "dark place" and then use it. This is anti-gravity technology.
.
But if you find the anti-gravity hiding in the "dark place", how to use the anti-gravity after you find the anti-gravity? This is the real difficulty and key point of this technology.
"No wonder the old man asked me to use anti-gravity technology to build my reputation as soon as he came. This anti-gravity technology sounds simple, but it is very difficult to actually do it. It is not just based on theory to find the anti-gravity hiding in the 'dark place'.
It’s an easy thing, let alone utilizing anti-gravity.”
"Even if you publish some papers on anti-gravity first, you don't have to worry about others researching anti-gravity technology first. There are three key points, one is the anti-gravity theory, the second is the search for anti-gravity, and the last is the support for anti-gravity.
energy."
"Only when these three problems are solved, can we truly put anti-gravity technology into practice. Without any of the conditions, anti-gravity technology can only exist in the laboratory and on paper. If you want to put it into practice,
It's definitely not that easy to make flying saucers like those in science fiction movies or novels."
After reading it carefully from beginning to end, Qin Yi finally figured out why the old man chose anti-gravity technology. You must know that this anti-gravity technology is so advanced. If he took it out to gain fame, it would be cheap for the whole world.
For other countries, the gains really outweigh the losses.
Now I am completely relieved. Anti-gravity technology is a very complicated and huge task. Even if you know the theory, you still have a long way to go to put it into practice. I also have the technology.
Tower this plug-in, otherwise they are all the same.
"Humph~ Without anti-gravity technology, with your current level on earth, it would be a matter of time before you could quickly enter the space age."
Sensing Qin Yi's thoughts, the old man held his hands and said slightly proudly.
ps: Don’t be too serious about technology, it’s meaningless~~
