What is time?

What Does Weather Mean

We explain what time is, the different meanings it has according to physics and philosophy and what its characteristics are.

The second (S) is the basic unit of time measurement.

What is time?

Time the term comes from the Latin tempus , defined c omo the duration of things that are subject to change . However, its meaning varies according to the discipline that addresses it.

Time in physics

In relativistic mechanics the time values vary according to the observer.

From Physics it is possible to define time as the separation of events that are subject to change. It is also understood as a flow of events . In this way the events are organized in sequences, allowing to determine the future, the present and the past. The International System of Units determined the second (S) as the basic unit of time.

In relativistic mechanics, the concept of time acquires a greater complexity when it is defined. This notion arises in opposition to the classical school, where it was understood that time was something absolute, that is to say that it is an exactly equal magnitude for all those who observe it . In relativistic mechanics it is understood that the time values can vary according to the observer, the reference system used and the point where the observer is.

Time in philosophy

Weather can also be an atmospheric state at a certain time and place.

From Philosophy , time can also be defined in different ways. This is a concept that has been treated since the ancient Greeks and continues to be so today.

  • From an Aristotelian conception this notion is related to movement , just as in physics. That is why time was defined as that measure of movement in relation to what preceded and what happened.
  • Other philosophers like Saint Augustine relate time to the soul. This relationship is due to the fact that the past is something that no longer exists, the future something that will come and the present slips away, becoming a memory, that is, the past.
  • From the Kantian theory, time is understood as a way of intuiting what happened, a virtue that belongs exclusively to man . Within this conception, time is not related to movement or external to people , but rather as something internal and personal, which allows organizing intimate experiences.
  • Currently there are various positions in philosophy when defining time, and for this various currents are used, such as existentialism , historicism, etc. For example, there are philosophers who define time as a conformation of two temporalities, one external and the other internal. Other scholars define time as the human essence.

Finally, we can mention another meaning of time, the one referred to the atmospheric time. In this case, it is defined as an atmospheric state at a certain time and place . In other words, it depends on factors such as atmospheric pressure , temperature , cloudiness or the absence thereof, wind and its peculiarities, humidity, among others, always within a certain space.
