What are the laws of nature? What are the common laws of nature

The intrinsic and essential connection of natural phenomena is manifested as the immutability under certain conditions. Mankind's understanding of the laws of nature has developed with the development of natural science, and this understanding has an intuitive nature in ancient times and has the characteristics of mechanistic theory in modern times. In modern times, mankind's understanding of the laws of nature has not only overcome the one-sidedness of ancient and modern times, but has also been expanded and deepened.

The laws revealed by modern natural science can be broadly divided into two categories:

The law of mechanical determinism. According to this law, the state of the material system at each moment is determined by the initial state of the system and the boundary conditions of the system. The dynamical law expressed by integrable differential equations is a typical manifestation of this law, and its solution is determined by the initial and boundary conditions of the system.

Statistical laws. This law is the integral characteristic of a system composed of a large number of elements, and any single element in the system remains subject to the laws of mechanical determinism. Statistical physics equations are typical of this regularity, and their solution depends on the statistical average of the corresponding dynamics of the elements of the system at the initial moment.

There are two different understandings of the statistical characteristics of quantum mechanics. One view is that the statistics of quantum mechanics are the behavior of quantum systems, and that individual microscopic particles do not have random behavior. However, most physicists hold a different understanding, arguing that although the quantum states of quantum mechanical microsystems provide objectively measurable sums, it is not possible in principle to make a single-value prediction about the behavior of each microscopic object, and only the probability of the occurrence of each possible behavior.

Therefore, the statistics of quantum mechanics are manifested by the interaction of individual particles with the instrument. It is now found that most of the differential equations of complex mechanical systems are non-integrable, because these equations themselves have "intrinsic randomness", that is, the behavior of the system they describe cannot be determined by the initial conditions singarily. As a result, some people believe that this is an inherent law of randomness that is different from the laws of mechanical determinism and statistics.

Laws are also called laws. The essential connection in the development of objective things has a universal form. Law and essence are concepts of equal degree, and both refer to aspects inherent in things themselves, which are hidden behind phenomena and determine or govern them.

However, essence refers to the internal connection of things, which is composed of the internal contradictions of things, while law refers to the essential relationship or stable connection between essences of the same kind of phenomena in terms of the development process of things, and it is the relatively static content of the ever-changing world of phenomena. Laws work repeatedly, and as long as the necessary conditions are met, the phenomena that conform to the law will inevitably recur. The things and phenomena in the world are very different, and they all have their own laws that are different from each other, but in terms of their fundamental content, they can be divided into natural laws, social laws and thinking laws.

The laws of nature and the laws of society are both laws of the objective material world, but they are manifested in different forms: the laws of nature are manifested in the interaction of various unconscious and blind dynamics in nature; The laws of society must be expressed through people's conscious activities. The law of thinking is the reflection of the subjective form of human thinking on the objective law of the material world.

Common natural laws include: ebb and flow, flowers bloom and fall, spring, summer, autumn and winter, summer is warm and winter cool, gravitational force, etc., including Darwin's natural selection, survival of the fittest, etc., are common natural laws in life.

The laws of nature are the intrinsic, essential, and stable relations of the movement of matter, which is manifested in the fact that as long as the corresponding objective conditions have this law, its effect is immutable, otherwise this law will be invalid, and all kinds of laws do not interfere with each other, and they are not transferred by human will, and the same is true of social laws.

The laws of nature are the intrinsic, essential, natural, and stable relations of natural phenomena.

Social law is the essential, natural, and stable relationship between the phenomena of the social life process manifested by people's activities.

The connection between the two: both have an objectivity that is not subject to human will. Man cannot arbitrarily change, create, or destroy the laws of nature; However, man can transform nature and purposefully regulate the physical energy and information processes in nature, so that the results of the joint action of various objective laws are conducive to man's change or maintain stability in favor of man.

The difference between the two is that the laws of nature act as a blind unconscious force, while the laws of society are realized by the conscious activities of people with certain goals and intentions. In the social law, there is a relationship between objective laws restricting subjectivity, and there is also a relationship between subjectivity and objectivity.

As long as the laws of nature have the same objective material conditions, they can be repeated in the same form. It is much more difficult to understand the laws of society than to understand the laws of nature.

1. Different influences: 1. Social laws: Because in class society, most of the social laws directly involve the interests of different classes, and the discovery and use of them are often realized in the class struggle. 2. The laws of nature:

Different classes and groups can use the laws of nature to serve themselves without directly involving the interests of the class, and only in the purpose and direction of use can they have a certain class character.

2. The effective time is different 1. Social law: The effective time for social law to work is generally much shorter. 2. Natural laws: The effective time of natural laws is relatively long.

3. Different roles 1. Social laws: The role of social laws is manifested through people's purposeful and conscious activities. 2. Natural laws: Natural laws can act without human practical activities, such as solar eclipses, wind and rain, thunder and lightning, etc.

1. The laws of nature act as a blind unconscious force, while the laws of society are realized through the conscious activities of people with certain goals and intentions.

2. As long as the laws of nature have the same objective material conditions, they can appear repeatedly in exactly the same form. Social laws are historical, and they have different manifestations in different societies, countries, nations, and different historical stages.

The laws of nature are: autumn leaves, frogs hibernate, the fifteenth moon of each month, the earth rotates 24 hours a week, and the revolution rotates for one year. The sun rises in the east and sets in the west, and the earth rotates from west to east; Spring, summer, autumn and winter, the scenery is different in the four seasons.

The survival of the fittest, natural selection, the strong eat the strong, the community is connected by the food chain and the food web, the population will survive through the struggle for survival, competition with each other, etc., the evolution of organisms is determined by natural selection, people can not violate the principle of the bright chain of food and the food web, the rotation of the earth, the sun rises in the east and sets in the west, day and night, rain and snow and other natural phenomena.

The law of development and change that exists in nature itself. Also known as the law of nature sells keys. Mao's Youth League's Work Should Take Care of the Characteristics of Young People

Young people are no weaker than we are. The elderly have experience, of course, they are strong, but their physiological functions are gradually degrading, their eyes and ears are not so agile, and their hands and feet are not as agile as those of young people, which is the law of nature. ”

The laws of nature mean the laws that exist within objective things in nature.

The laws of nature are the intrinsic, essential, and stable relations of the movement of matter, which is manifested in the fact that as long as the corresponding objective conditions have this law, its effect is immutable, otherwise this law will be invalid, and all kinds of laws do not interfere with each other, and they are not transferred by human will, and the same is true of social laws.

The laws of nature refer to the intrinsic and inevitable relationship between the movement, change and development of objective things without human intervention, also known as the laws of nature. According to the Modern Chinese Dictionary, the laws of nature refer to "the laws that exist within objective things in nature", that is, the intrinsic, essential and stable relationship between the movement of matter.

Mankind's understanding of the laws of nature has developed with the development of natural science, and this understanding has the characteristics of mechanism in ancient times and in modern times. In modern times, human understanding of the laws of nature has not only overcome the one-sidedness and isolation of ancient and modern times, but has also been expanded and deepened.

Common natural laws include: ebb and flow, flowers blooming and falling, spring, summer, autumn and winter, warm summer and cool winter, gravitation, etc., including Darwin's natural selection, survival of the fittest, are common natural laws in life, all of which need us to understand and adapt.

The laws of nature are the basic rules and laws that describe and explain natural phenomena and the operation of the world. Here are some common laws of nature:

1.The law of gravitation (law of gravitation): there is a gravitational interaction between masses, and the specific magnitude is related to mass and distance, proposed by Newton.

2.Laws of thermodynamics: The first law of thermodynamics (the law of conservation of energy), the second law of thermodynamics (the law of increasing entropy), and the third law of thermodynamics (the law of the impossibility of cooling to absolute zero) describe the relationship between heat and energy.

3.Wave law: including the propagation law of light (the linear propagation and refraction of light), the propagation law of sound waves (the propagation of sound requires a medium), etc.

4.Electromagnetic laws: including Coulomb's law (the force between electric charges) and Maxwell's equations (which describe the behavior of electromagnetic fields).

5.The Law of Conservation of Matter: Matter is not created or destroyed in a closed system, only transformation.

6.Laws of motion: including Newton's laws of motion (the laws of motion of objects under force), the law of conservation of momentum, and the law of conservation of angular momentum.

7.The laws of life: including the laws of heredity in biology (such as Mendel's laws of inheritance) and the laws of ecological balance in ecology.

8.Chemical reaction law: including chemical equilibrium and rate law, etc., which describe the relationship between the concentration and rate of substances in the process of chemical reaction.

These are just a few of the common laws of nature, and there are many laws and laws in nature that scientists continue to prove and explore through observation and experimentation. Different disciplines have their own research content and rules. <>
