What is Substance? How is matter created?

Matter originated from the universe a long time ago, and all the physical objects that make up the universe are matter, and matter exists objectively and does not change due to the change of people's subjective consciousness.

Organic or inorganic substances with a specific molecular structure. is made up of molecules. And it also contains nuclei and electrons. These components ultimately make up the substance.

Material things are what people need in life. Matter is produced according to the things that people need in life, and there is a link between material and human life.

This is a term of physics, which refers to the basic things that make up everything in the universe, matter has existed since the establishment of the universe, and it is not clear how it came into being.

Matter refers to the objective reality that does not depend on human subjective consciousness but can be reflected by human consciousness, relative to consciousness. The relationship between matter and consciousness is like the relationship between concrete and abstract, matter is a concrete thing that can be seen and touched, while consciousness is built on matter, abstract and opposite to matter.

Motion is the fundamental property of matter, and time and space are the forms of existence of matter in motion. All images of nature and society are forms of existence of matter in motion.

The concept of matter in Marxist philosophy is the highest summary of the fundamental characteristics of all phenomena in the world (natural and social), and therefore it cannot be confused with the doctrine of the structure of matter in the natural sciences.

The world is unified in matter. The only property of matter is objective reality. The material world can reflect people's feelings and consciousness, but it is not exhaustive. The concept of matter is the foundation of materialist philosophy.

Since the beginning of the 20th century, the new understanding of the properties, structure, and form of matter in the natural sciences has continuously confirmed and enriched the material category of dialectical materialism.

Lenin's definition of matter: matter is a philosophical category that marks objective reality, which is perceived by man through his senses, which exists independently of our senses, and is reproduced, photographed, and reflected by our senses.

Movement is the way in which the object of travel exists. Objective reality is the basic characteristic of matter, the universal essence of matter. It is expressed through movement.

People understand matter itself by understanding its motion. Movement is the most abstract philosophical category. It encapsulates the general nature of all changes and processes, including changes in nature, human society, and the human mind.

Matter is in motion.

Matter is the bearer of motion, the true basis of all movement and development; Motion is the intrinsic basic property of matter, and it is the mode of existence of all material forms. The mode of existence of matter (basic property): motion.

Matter is the material in motion (the movement of the material world is unconditional, eternal, absolute); Motion is the movement of matter (matter is the carrier and subject of motion); Filial piety stool.

Matter is the physical objects and fields that make up all the objects in the universe. All entities in the world are matter, and the human body itself is also matter. Apart from these objects, light and electromagnetic fields are also substances.

They are substances that exist in the form of fields. There are many types and forms of matter, and the properties of matter are varied.

Matter is an objective existence that does not depend on human consciousness, and it can be reflected by human consciousness. First of all, the phrase "matter does not depend on human consciousness" tells us that matter exists whether there is consciousness or not, which proves that the world has matter first, and then there is consciousness, which is a materialist view. Second, "human consciousness can reflect matter" tells us that human consciousness can know matter, which is the agnostic view.

1. Definitions. Lenin's definition of matter is: "Matter is the philosophical category that marks objective reality, which man perceives through his senses, which exists independently of our senses, and which are reproduced, photographed, and reflected by our senses." ”

Abbreviation: Matter is an objective reality that is independent of consciousness and can be reflected by consciousness.

2. Significance. Lenin's definition of matter is of multifaceted importance

First, it states that matter "exists independently of our senses", affirms the independence and rootedness of matter from consciousness, and draws a clear line from dualism and idealism.

Second, it points out that "objective reality is perceived by man through his senses", adheres to the materialist principles of reflection and agnosticism, and draws a clear line with agnosticism.

Third, it points out that "matter is a philosophical category that marks objective reality", clarifies the difference and connection between the philosophical material category and the material theory of natural science, and draws a clear line with the old materialism.

Matter is the physical objects and fields that make up all objects in the universe, such as air, water, food, cotton, oil, various metals, plastics, and so on.

When many students study physics, they are often exposed to the concept of matter, but their understanding of the concept of matter is vague, so what is matter? Let's find out.

01 In the world, all the existence around people is material. The human body itself is also a substance. In addition to these physical objects, light, electromagnetic fields, etc., are also substances, and they are substances that appear in the form of fields.

There are many types and forms of matter, and the properties of matter are varied. Substances in the gaseous state, substances in the liquid state, or substances in the solid state; elemental substances, compounds, or mixtures; metals and non-metals; minerals and alloys; inorganic and organic; naturally occurring substances and synthetic substances; Inanimate matter and living matter as well as solid matter and field matter, etc.

02 Although there are many types of matter, they have their own characteristics, that is, they can be observed or predicted by theories, and they all have mass and energy. Having different chemical formulas is different substances, and having the same chemical formula but having different structures is also different substances.

03 There are six common states of existence of matter: solid, liquid, gaseous, plasma, ultra-solid, and neutron. However, advances in experimental techniques have produced many new states of matter, such as Bose-Einstein condensation and fermion condensation.

The study of elementary particles has also led to new states of matter, such as quark-gluon paste. In the history of the natural sciences, many people have studied the exact properties of matter, the notion that matter is a combination of many discrete components, the so-called "particle theory of matter", first proposed by the Greek philosophers Leucipus (c. 490 BC) and Democritus (c. 470 380 BC).

04 Macroscopically, there are many types and properties of matter. Substances in the gaseous state, substances in the liquid state, or substances in the solid state; elemental substances, compounds, or mixtures; metals and non-metals; minerals and alloys; inorganic and organic; naturally occurring substances and synthetic substances; Inanimate matter and living matter as well as solid matter and field matter, etc. Although there are many types of matter, they have their own characteristics, that is, they exist objectively, can be observed, and they all have mass and energy.

05 The difference between matter and object: In terms of connotation, matter is a filling content that is never evenly filled in time and space, and its only property is mass. In terms of extension, matter refers to all objects, including "spiritual objects" and "real objects".

The three elements of the universe are time, space, and mass. Mass and space are the basic properties of objects, while mass, space and time are the basic properties of events.
