Gravitation (Chinese mainland is often referred to as gravity, Taiwan is mostly called gravity in physical situations, because although the general mass of matter is positive, so it is always gravity, but the force presented by the quantum field of negative energy is repulsion, not gravity, so it is appropriate to call gravity) is an attraction between all objects with mass. The magnitude of the gravitational force between two objects is directly proportional to the product of the masses of the two objects and inversely proportional to the square of the distance between the two objects. The gravitational force acts on the line connecting the centroids of two objects.
The formula for gravitational force is:
Among them, it is called the gravitational constant (gravitational constant).
That is, the magnitude of the gravitational force between two particles is proportional to the product of their masses and inversely proportional to the square of the distance between them, in the direction of their lines.
This formula is only applicable if the distance between two objects is much greater than the geometric dimensions of the object, and the object can be approximated as a particle. Otherwise, the object should be divided into small enough particles, the gravitational force between the two should be calculated, and then the integration should be performed.
History. In ancient times and the Middle Ages, gravitation was considered a property of location, not of matter.
From the 17th century onwards, scientists considered gravitation to be a property of matter. The force with which one object attracts another depends on the amount of matter it contains and the distance separating them, and this force is interactive. Copernicus believed that gravity is a way of agglomeration of matter, and that the center of gravity is a point of geometric nature.
In 1600, William Gilbert proposed that magnetism may be the principle that sustains the existence of the solar system. He imagined that gravity was the magnetic force of the Earth, a huge magnet, acting on the surrounding objects, and that it would spread throughout the solar system and become the outer membrane of the universe. Gilbert proved that the amount of magnet attraction to a piece of iron depends on the size of the magnet, and that the larger the magnet, the greater the attraction on the iron.
And the attraction is interacting, the magnet attracts iron, and the iron also attracts the magnet. His research provides a model for modern notions of gravity. The center of gravity is not a geometric point, but a specific pile of matter, and its force increases with the amount of matter.
Kepler developed Gilbert's concept of gravitation, which he postulated as something similar to magnetism, a mutual induction between objects of the same sex, depending on the size of the object.
Later Newton discovered the relationship that the gravitational force between two objects decreases with the square of the distance between the objects. and proposed the law of gravitation (the law of gravity).

Concentration refers to the ability to be very focused on one thing, to be able to concentrate all your mind on one thing. This is concentration.
-
Concentration is based on awareness, and concentration without awareness will only lead to ignorance, but without concentration awareness, its power is very weak. The so-called unity of knowledge and action is the balance of awareness and concentration. Awareness is a premise, it is not difficult for a wise person to get a glimpse of the true meaning of life, but this is not enough to fundamentally change the madness in our hearts, the power of habits is particularly strong, our awareness of life can not be just short-lived, superficial, we have to go deeper.

What Buddhism says is, the mud can't hold up the wall, if you scold him, he will laugh, donor, Amitabha, scold, he's still, donor, Amitabha, make you angry to death, this monk is fine, this is concentration.
Then these monks sit and eat empty mountains, and they are very greedy for money, and he immediately ran away when he met the devil's well village, because Buddhism does not kill, and always prompts you when you ask for money, donate money, accumulate virtue, and shape a golden body, in fact, it is to scrape your money to satisfy your selfish desires, get it without work, and wash your brain, Buddhism says that cultivating into a Buddha is to build yourself into the greatest material wealth of the Buddha to enjoy the spirit, and to put it bluntly, it is the end of the ultimate great greed. So they are all lazy people, all parasites of society.

"Concentration[1] is a Buddhist language. The core or general outline of the 12 classics of Buddhism is the three schools of "precepts, concentration, and wisdom", precepts are precepts, determination is meditation, and wisdom is wisdom. Among the three learnings, "determination" is the center of Buddhism, and there are Buddhist scholars
In a broad sense, concentration does not only refer to meditation, but also the practice of concentration is intended to cultivate one's concentration. People with concentration are steadfast in mindfulness, such as pure water without waves, not with logistics, not for the environment, above board, open and selfless. A person with concentration has a pure heart, if he does not move, he is not deceived by illusions, he is not moved by fame and fortune, and he will naturally open his mind when he studies and practices to a certain extent.
It can be seen that the concentration of a practitioner of the Dharma is crucial to whether or not he can achieve positive results.

Concentration refers to the ability of a person to control his desires or behaviors, not to be tempted by profit, not to be burdened by fame, not to be trapped by feelings, not to be embarrassed, not to be confused by danger, and to concentrate on a certain thing.
Concentration is a kind of selective force, anti-interference, distinguishing right from wrong. Selectivity is the integration of identification, judgment, and trade-offs. The vast universe is all-encompassing, and human society is complex, and it is impossible for a person to exhaust all the affairs of the world.
A person's life is a life of choice, and choice determines success or failure.
The meaning of concentration lies in the value of choice. Most of the choices are carried out in various interferences and uncertainties, with costs and risks, and require a pair of sharp eyes to distinguish between good and evil, true and false. The choice is a fixed force sight. Concentration is oriented first, which is the ability to choose correctly.
The Buddhist Meaning of Concentration:
"Concentration" is a Buddhist term. "Concentration" is one of the meditation forces that clears away disturbing emotions and delusions.
In Buddhism, there are "five forces", and "concentration" is one of the "five forces". The "five powers" refer to the five powers that can break down obstacles and liberate people, including "faith", "perseverance", "mindfulness", "concentration" and "wisdom". The "five forces" also refer to "concentration", "kone", "borrowing knowledge", "great will" and "fawei deli".

Concentration is a reaction to a person's psychology when encountering things. For example, if something happens, many people will settle down, and some people will be furious. Why is that?
It is precisely because of his own uncertain mind that he cannot get rid of his afflictions, he cannot disconnect from his afflictions, he cannot disconnect from greed, because greed is the main factor of uncertainty. Therefore, a person who has too many greedy thoughts, too many blind thoughts, and too many stupid thoughts will have very little concentration. Because the mind cannot be settled, the person will slowly become unwise, and without wisdom the person will make mistakes.
Therefore, a truly wise person must know how to concentrate, and concentration is to lock one's heart with a special kind of wisdom. When greed comes, I am not greedy, but I have fixed my heart. When I want to hate others, I don't hate them, and I fix my heart again; When you want to be stupid and do something bad for others, you can fix yourself. In fact, this is the fixed thought, and the fixed thought can make you have concentration.
Therefore, if a person's thoughts are not right, his mind and his abilities will definitely not be focused.
