A stopwatch is a device used to measure time accurately.
Time is a word derived from the Latin tempus , which is used to name a physical magnitude , which is used to measure the duration of something susceptible to change. When something changes from one state to another, and this change is noticed by an observer, this period can be quantified and measured as time.
For example: "I should stop by Marcos's house, but I don't have time today" , "Do you want to go to breakfast? We have plenty of time" , "There's no more time to wait: tell Grontter now that we reject his proposal" .
We often hear talk of earning it, losing it or saving it, but the truth is that we cannot even hoard it. Time moves inexorably forward and there is nothing we can do to change its course. It is impossible to make it develop more slowly or more quickly, or to try to save a little for the future.
Sequential organization
Thanks to time, we can organize events sequentially or in a chronology. This order establishes a past (what has already happened), a present (what is happening at the moment) and a future (what will happen soon).
The division of time, meanwhile, allows for the organization of life. Depending on the need, units such as seconds , minutes , hours , days , weeks , months , years , decades , centuries or millennia are considered.
As we have already indicated, the acceleration of time is not possible, just as time dilation is not possible. However, the perception of the duration of moments or stages often varies even if the clock remains unchanged and the calendar advances normally.
In this context, it is common for the working day to seem longer than a holiday or weekend , even though the days last exactly the same. Similarly, in adulthood or old age, time seems to move faster than in childhood or adolescence.
There is no exact date or specific moment when this perception changes, but rather it is part of emotional development and the experiences experienced. It should also be considered that, when appealing to memory and remembering past events, distortions occur: nothing is remembered exactly as it happened.
Many people feel that leisure time is scarce.
Time in literature and cinema
It should be noted that the game that can be established with the different types of time has been the inspiration for various arts, such as literature or cinema. Thus, for example, in the first field it is worth highlighting the existence of books such as "The Time Machine" by the writer HG Wells .
This novel, classified as a science fiction novel, was published in 1895. It tells the story of a scientist in the 19th century who makes a very unique invention: a vehicle that allows him to travel through time and that will allow him to see both the past and the future.
In the same vein is the trilogy of films titled "Back to the Future" (or "Back to the Future" ), which was brought to the big screen by filmmaker Robert Zemeckis . The film stars Dr. Emmett Brown (played by Chris Lloyd ), a somewhat eccentric scientist who uses a car as a means of transportation to travel through time, and his friend Marty McFly ( Michael J. Fox ). The latter will be the one who, along with the former, will make those unique trips that will lead them to discover the past and future not only of themselves but also of their loved ones.
The film "Groundhog Day" stars Bill Murray and Andy McDowell . It tells the story of a television presenter, played by the former, who experiences the same day over and over again for a period of time.
Time travel often appears in literature and cinema.
Atmospheric conditions
It is possible to associate time with something that is not strictly related to this order. The concept of atmospheric time refers to the phenomena that occur in the atmosphere of a planet and that are known, when they reach a certain temporal stability, as climate .
Rain , wind , hail and snow are some of the weather phenomena that occur on Earth and that determine the living conditions of human beings and other species.
Paying attention to the weather is a daily routine for almost everyone. Looking out the window at dawn helps you know what to wear so as not to feel cold or hot when you leave the house, for example. Checking the weather forecast , on the other hand, is useful when planning the organization of a birthday or anniversary party.
It is important to note that the weather is linked to the seasons and times of the year, and even to the time of day. Summer is warmer than winter, and temperatures are usually higher at midday than at midnight, to name a few common circumstances.
