The Greek horízōn came to Latin as horĭzon , which in turn in our language became horizon . This is the name given to the line in which, to the naked eye, the earth appears to meet the sky .
Suppose a person is in the middle of the field, without any buildings nearby or trees or large plants. When you look into the distance, you will notice that, at a certain point, the earth's surface seems to meet the sky: that union is the horizon.
There are various types of horizon: the real horizon , the apparent horizon , the optical horizon , the geometric horizon , etc. In each case, the definition varies depending on the plane being considered, the observer's point of view and other issues.
It is important to keep in mind that the horizon is linked to the curvature of planet Earth and the phenomenon of refraction . This means that what is on the horizon can be partially hidden.
In addition to all of the above, we cannot ignore that in the field of geology the term we are now dealing with was introduced into that field professionally by the geologist Samuel P. Woodward (1821 – 1865). Specifically, he chose to use this word in 1856 through his work titled “Manual on Mollusks III.”
In the same way, we cannot forget the existence of what is known as the event horizon or also called the event horizon. Specifically, it is a term that is used within the scope of general relativity to refer to a hypersurface that acts as a border of space and time, which means that events that take place on one side of it do not affect in no way to an observer who is located on the other side of it.
Not to mention that in the field of chemistry there is also talk of the Cauchy horizon.
The concept of horizon also has other meanings. It may be a landscape , a site or a boundary . For example: “I would like to travel thanks to my art and reach distant horizons” , “The horizons of the kingdom are well protected by our soldiers” , “The most beautiful horizons began to happen in front of our eyes” .
Horizon, on the other hand, can refer to a time period that is expected for something or to the perspectives linked to a project or issue: “I think the government should consider a three-year horizon to reduce inflation,” “We have to see more beyond the daily horizon if we want the company to survive over time” , “What would be the long-term horizon of this initiative?” .
In addition to everything indicated, it must be emphasized that there is a very famous wine within the La Rioja Designation of Origin that responds to the name Horizonte de Exopto or that there are different films that have the word in question in their titles. An example of the latter is the film “Horizons of Greatness”, which belongs to the Western genre and was released in 1958 under the direction of William Wyler and with Gregory Peck as the protagonist.
