How to understand communication (macro and micro)

Macroscopically, physical terms do not involve the internal structure or mechanism of molecules, atoms, electrons, etc. All objects visible to the naked eye are macroscopic objects; Macro phenomena generally refer to various phenomena of macro objects and fields within the scope of macro space; Macro objects and macro phenomena are collectively called the macro world.

Let's look at it from the perspective of social science. In social science, generally speaking, we usually call the science we study and grasp from the big aspect and the whole aspect as macro science, and this research method is called macro method. Usually, the science that is studied and grasped from small aspects and local aspects is called microscopic science, and this research method is called microscopic method. As opposed to "macro". Generally speaking, the spatial linearity is less than 10? -7~ 10? -6 cm material system. Including molecules, atoms, nuclei, elementary particles and their corresponding fields. Elementary particles also have their internal structures. All levels of the micro-world have wave-particle duality, and they all obey the laws of quantum mechanics.

As the name implies, macro refers to observing from a big angle, and micro refers to observing from a small angle. Sometimes, we often use the concept of meso, that is, between macro and micro.
