Lorentz Equation

1. The Lorentz transformation formula is x=(x′+ut′) /√(1-u^2/c^2)t=(t′+ux′/c^2)/√(1-u^2/c^2).

2. The formula of Lorentz force is F=Bqvsinθ (θ is the angle between v and B). The force to which the kinetic charge is subjected in the magnetic field is called the Lorentz force. The Lorenz force is named after the Dutch physicist Hendrick Lorenz. According to the law of Lorentz force, Lorentz force can be used as an equation called the Lorentz force equation.

3In electrodynamics, Lorentz force is the force on charged particles moving in the electromagnetic field.

4. The integral form of the Lorentz force equation is, in which V is the volume of the integral, p is the charge density, J is the current density, and dr is the tiny element. Definition: The force on which the moving charge is subjected in the magnetic field is called the Lorentz force, that is, the force of the magnetic field on the moving charge. The formula of Lorentz force is F=QvB.

The principle of the butterfly effect

1. The reason is that the movement of the butterfly's wings causes changes in the air system around it and causes the production of weak airflow, and the production of weak airflow will cause the air around it or other systems. Corresponding changes occur, which causes a chain reflection, which eventually leads to great changes in other systems.

2. As follows: The butterfly effect means the result of the development of things, which is extremely sensitive to the initial conditions. The very small deviation of the initial conditions may cause great differences in the results. It's like a butterfly. It seems insignificant, but it may also cause a storm because of the slight fluttering of the butterfly's wings.

3. The Butterfly Effect refers to a long-term huge chain reaction in a dynamic system in which small changes under the initial conditions can drive the whole system. This is a kind of chaotic phenomenon. If a butterfly flaps its wings gently in the tropics, a distant country may cause a hurricane.

4. The philosophical principle of the butterfly effect is mainly the view of connection. First of all, this principle believes that the world is a unity composed of various things interconnected.The internal elements of each thing are interconnected to form a unified whole, and at the same time, each thing is also connected with other things externally to exist.

5. The principle of the butterfly effect is as follows: "A butterfly in the Amazon rainforest occasionally flaps its wings a few times, which can cause a tornado in Texas, the United States in two weeks. This is the butterfly effect.

System and Understanding Level

When the brain deals with things, there will be six different logical levels, from low to high, divided into environment, behavior, ability, belief value, identity and system. To understand things, we should also start from a systematic and overall balanced perspective. The higher a person can stand at a higher level to understand things, the more he can take care of the whole situation and the better he can solve problems.

[My harvest]: Understanding level: system, identity, beliefs and values, ability and behavior, environment. Through in-depth understanding of ourselves or others, we have a deeper understanding through communication.

Understanding the hierarchical model is divided into the upper three layers and the lower three layers. The lower three layers are the part of consciousness, which are divided into environment, behavior and ability. The upper three layers are the subconscious part, which are divided into beliefs, values; identity and system.

System: Your relationship with various people and things in the world (the meaning of life) [detailed steps to understand the hierarchical method] Preparation First of all, set a goal, and you should clearly understand what this goal is. Environment Think about the information of people, things, things, time and places related to the "goal".

follow: reasonThe upper four layers of the solution level (system, identity, belief value, ability) (2) are: the changes of the following two layers (behavior, environment). Understanding the level can help us better understand ourselves and others. Understanding the affirmation of hierarchical identity and system can increase a person's inner strength.
