The books in the science and technology tower are different from the textbooks we usually use in learning, although the appearance in the science and technology tower is the appearance of books, but in fact, there are many forms and methods of transferring knowledge.

For example, in the simplest way, we calculate the area of a triangle, and we all know that the area of a triangle is calculated by multiplying the base by half of the height, and as for how this formula is derived, many of us have not thought about this problem carefully.

In the technology tower, if the technology tower comes to teach you how to calculate the area of the triangle, he will change a triangle in the form of dynamic animation, so that you have an intuitive understanding, as long as the base length and height are the same, no matter how the triangle changes, its area is the same.

The books in the science and technology tower, when it imparts knowledge, are not only words, but also language, pictures, videos, and the process of derivation, combined with the practicality of this knowledge point.

When you learn, you may learn a lot more, but the impression is more profound, and the scope and depth of knowledge are expanded, and you can also cultivate a reverse deduction thinking, and combine it with reality to apply what you have learned.

At this time, Qin Yi looked at the book about anti-gravity technology, which was directly presented in Qin Yi's mind with videos, pictures, texts, etc., so that it was convenient to better learn and understand the principle of anti-gravity.

Before understanding antigravity, we must first understand what gravity is?

The force exerted by an object due to the attraction of the earth is called gravity, according to Newton's law of gravitation, objects with mass have gravitational force, and the greater the mass, the greater the gravitational force, and the gravitational force on the earth is the gravitational force of the earth.

Of course, this is only our understanding of gravity according to Newton's law of gravitation, and in fact Newton's law of gravitation has many natural phenomena that cannot be explained.

One of the most important is the paradox between the accelerating expansion of the universe and the law of gravitation, according to the traditional Big Bang theory, the universe is constantly expanding because of the Big Bang, and the expansion of the universe is gradually slowed down by the gravitational pull between galaxies.

However, in 1998, scientists found that the expansion of the universe was not decelerating, but accelerating, which was actually inferred by the redshift between galaxies.

This phenomenon cannot be explained by Newton's law of gravitation, so scientists put forward the idea of dark matter and dark energy, which are widespread and account for the majority of the total mass of the universe.

In addition to the phenomenon of accelerating expansion of the universe that cannot be explained, there are also gravitational anomalies on the earth, and the weight of the same object at the same altitude, in the same dimension, and in different places is different, which is the weight anomaly.

In addition, there will be some peculiar places on the earth, such as a place in Taiwan where there is a section of river that will present the spectacle of water flowing to a high place; In some parts of the planet, gravity is abnormally high; In some areas, the trees are tilted uniformly, and people cannot stand up straight.

In fact, we only know gravity and gravity, but if we think deeply, what is this gravity?

Just like light, we know that it is a photon after we understand it deeply, and we know that the propagation form of light is in the form of light waves.

In the same way, what exactly is gravity? What is it made of? And in what form is it disseminated or moved?

Of course, scientists on the earth have thought and studied this aspect very early, and scientists have put forward the idea of 'electric field force', in the center of the earth, at a pressure of 3.6 million atmospheres and a high temperature of 6,000 K, the earth's 'solid core' will definitely not be a solid substance at our room temperature, and it can be inferred that it is a huge positive electricity according to the laws of physics.

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 when the energy is large enough (thermal electron emission); The principle of nuclear fusion reaction proves that when an atom is subjected to enormous heat and pressure, most of the electrons outside the nucleus escape.

Under the action of the gravitational force of the macroscopic positive electric field of the earth's core and the ampere force in the magnetic field, the escaping electrons will form a negative electric layer in the mantle, and form an inner and outer polar capacitor with the positive electric field of the earth's core.

Due to the cancellation of the electric potential between the internal and external electric fields and the large insulating layer of 'tens of kilometers thick crust', the surface always reflects neutral characteristics, and the gravitational pull of the negative electric field in the mantle layer will attract all the material on the entire crust and surface to form gravity.

But this point of view was not recognized by scientists, because there were many different interpretations, and at this time, in Qin Yi's mind, all the knowledge about gravity was presented.

It is very simple to explain gravity with the content of the book, mass is the basic property of matter, and matter with mass will have a mass field.

The steady state of an object must be the form of existence when the center of mass of the object is in a state of symmetry between the mass field of the object. Once there is an asymmetry between them, the object must be in motion.

It is a natural phenomenon caused by the fundamental properties of matter and has nothing to do with the physical, chemical, and energetic properties 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, so that they will 'naturally' exhibit a state of motion between them, which is called free fall motion.

"I see, I only knew gravity before, but I never thought about the nature of gravity."

When he saw this, Qin Yi suddenly realized, and remembered that when he first learned gravity, he only remembered that Newton was hit on the head by an apple, and 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, but I didn't expect that the movement of gravity is also a wave, a gravitational wave, Einstein is really good, and he has clearly recognized the essence of gravitational motion a long time ago."

After seeing the form of gravity movement and propagation, Qin Yi couldn't help but worship Einstein again, a cow man is a cow man, and he recognized the form of gravity movement and propagation very early.

Recognizing gravity clearly, 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 that "the theory of matter based only on attraction is wrong, inadequate, and one-sided." ”

Gravitational force and repulsive force are contradictory and unified, they coexist at the same time in matter and also in objects, which is the basic law of material structure, and should also be the basic law of macroscopic interstellar structure.

The microscopic particles have the motion and rotation of negative electrons around the positive electric nucleus, and the revolution between macroscopic stars and the rotation of stars should also be electromagnetic interactions, and the physical properties of macroscopic and microscopic matter should be the same.

Anti-gravity is actually a force that is the opposite of gravity.

"I see, gravity is the most direct manifestation in front of us, and anti-gravity is a hidden feeling, the moon has not fallen, in addition to its own distance from the earth, a more important reason is because of the existence of anti-gravity, or the existence of repulsion."

Soon, Qin Yi had a feeling of sudden enlightenment and sudden opening, according to the content of the book, gravity and anti-gravity are like one yang and one yin, one in the light and the other in the dark, we feel the existence of gravity at most, but we do not feel the existence of anti-gravity, because the expression of anti-gravity is in the 'dark place'.

"The principle of anti-gravity technology is to make full use of the anti-gravity force hiding in the 'dark place', so as to achieve a technology that flies out of the earth's gravity."

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 hidden in the 'dark place', and then use it, this is the anti-gravity technology.

However, if you find the anti-gravity force hiding in the 'dark place', how to use the anti-gravity force after finding it, this is the real difficulty and key point of this technology.

"No wonder the old man asked me to use anti-gravity technology to make a name for myself, this anti-gravity technology sounds simple, but it is very difficult to do, it is not easy to find anti-gravity hiding in the 'dark place' according to theory, not to mention the use of 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, which has three key points, one anti-gravity theory, the second is the search for anti-gravity, and the last is the energy source that supports anti-gravity."

"Only when these three problems are solved can we say that anti-gravity technology can be truly used in practice, without any conditions, anti-gravity technology can only exist in the laboratory, on paper, and it is absolutely not so easy to make flying saucers like 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 high, if he takes it out and cheapens other countries in the world in order to brush up his reputation, it will really outweigh the loss.

Now it's completely relieved, anti-gravity technology is a very complex and huge work, even if you know the theory, you still have a long, long way to go if you want to use it in practice, and you also have the plug-in of the science and technology tower, otherwise it's all the same.

"Hmph~ There is no anti-gravity technology, and if you want to quickly enter the space age at the current level on your earth, I don't know if it is the Year of the Monkey."

The old man sensed Qin Yi's thoughts, and hugged his hands and said slightly proudly.

PS: Don't be more serious about technology, it's not interesting to be more serious~~
