What is Circle?

The word circle comes from the Latin word circulus, which is the diminutive of circus (“fence”). It is a synonym for round and, in everyday language, for circumference.

A circumference, however, is the locus (set of points) on a plane that are equidistant from the center. The circle, on the other hand, is the locus of the points that are in a certain circumference. Therefore, the circle is the surface that is contained by the circumference, while this is the perimeter of said circle.

The center of the circle is coincident with the center of the circumference. The segment that allows the center to be joined to any point on the perimeter is known as the radius. The largest segment that passes through the center and generates two semicircles by dividing the circle is called the diameter.

As with cube and square, the terms sphere and circle are often used synonymously, although it is more common to hear the latter in any situation. Ever since the story of Christopher Columbus and his misquoted phrase ” the earth is round, ” people seem to ignore the depth of three-dimensional figures. This trend, like many others like it, is responsible for the difficulty many people have in understanding geometry and arithmetic concepts.

A very popular term is vicious circle, which represents a stage in the life of a person or a society that repeats itself indefinitely, usually with a negative connotation, since it seems impossible to interrupt. This series of events that take place in a cyclical way, are a mental trap not to overcome a depression, or not to cross a certain obstacle that prevents our progress. Beyond its daily use by people without technical knowledge, it is a phenomenon studied by psychology and there are various treatments that aim to guide the patient towards an alternative path, which allows him to finally advance.

It is known as a circle, in another sense, the organization or entity that allows a group of individuals who share interests to come together in a common (physical or symbolic) space. For example: “The Circle of Readers of the City of Buenos Aires has organized a meeting with poets and novelists”, “Tomorrow I have to go to an event at the headquarters of the Military Circle”, “Juan Eshicto was invited to read his texts in the Circle of Ibero-American Poets ».

The Círculo de Lectores was founded in Barcelona, ​​Spain, in 1962, seeking to become a network of authors and readers to bring literature to as many people as possible. His proposal is to offer special editions of a long list of titles, which is renewed every month. Over the years, its foundations have changed and the current market model, which demands quality products and services at zero prices, has undoubtedly affected this company. Subscribers receive a free catalog at home, although they agree in advance to purchase a certain number of books per month.

Readers’ Circle publications, which currently reach 63 countries around the world, do not have an attractive finish; This represents one of its weak points, although it is not the only one. Being a literary movement with an international presence, it would be expected that it would promote those authors really committed to letters, to enrich the readers; however, once again fashion and business trends prevail and triumph, leaving truly authentic and valuable content in the shadows.

Circle is also a certain environment or context of society: “The president’s words about abortion did not go down well in religious circles”, “There is uncertainty in financial circles due to the fall in long-term deposits.
