Time is an abstract concept, which shows the continuity and sequence of material movement and change. The concept of time includes two concepts: time and time period.
Time is a parameter used by human beings to describe the process of material movement or the occurrence of events. The determination of time depends on the law of material circulation that is not affected by the outside world.
Extended data:
Time exists objectively. The concept of time is the result of human understanding, induction and description of nature. In ancient China, its original meaning refers to the change of seasons or the position of the sun on the ecliptic. "Shuo Wen Jie Zi" says: Four o'clock is also four o'clock;
"Guanzi Shanzhong" said: When, so remember the year. With the deepening of understanding, the concept of time covers all tangible and intangible movements. There is a comment in the preface to Mencius: "It is said that time is also a branch of the five elements." Visible tense is used to describe the unified attribute of all sports processes, which is the connotation of tense.
Because the problems studied by the ancients are basically macroscopic, rough and slow-paced, and only pay attention to the problem of "time". Later, the concept of "time" was added to study fast and instantaneous objects.
Thus, time covers the continuous state and instantaneous state of the movement process, and its connotation is finally enriched and perfected, and the word "time" is finally finalized.
