The Greek word anomaly he came to Latin as anomaly, and then to Spanish as anomaly . The notion refers to a divergence , a incompatibility , a discordance or a detour of a rule or of a practice.

For example: “The child suffers from a chromosomal abnormality that generates various disorders”, "The investigation did not detect any anomaly in the mechanics of the vehicle", “The anomaly in the results of the clinical analyzes worried doctors ”.

The idea of ​​anomaly appears in different contexts. In the field of biology , talk about genetic anomaly when a pathology causes a genome modification. A chromosomal abnormality On the other hand, it is an alteration of the order or quantity of the genes inside the chromosomes.

In the field of physical , an anomaly describes a classic symmetry, such as being one of the Lagrangian that breaks by quantum effects. A Lagrangian It is a scalar function from which it is possible to obtain certain properties of a dynamic system, such as conservation laws and temporal evolution. Currently, it is the main operator to describe a physical system.

When talking about quantum effects, we refer to the quantum mechanics , a part of physics that is responsible for describing nature fundamentally in a scale small space Although the physical anomaly can be understood as a short-distance ultraviolet effect, which occurs because certain divergent integrals cannot be regulated so that all symmetries are preserved at the same time, there is also an infrared effect, since the The nature of these divergences is determined by low energy physics.

The concept also appears in the astronomy , where they talk about:

* eccentric anomaly : the angle that is measured from the center of the ellipse, and that serves to form the projection of the planet in the main circumference;

* average anomaly : a portion of a period of the orbit, which is expressed as an angle;

* true anomaly : the angle that is measured from the focus of the orbit and is formed by the planet with the axis of the ellipse.

A social anomaly , on the other hand, is a behavior or habit that avoids the conventional rules of society . It may be a permanent anomaly, which is sustained even if time progresses (as an addiction), or a periodic anomaly, which is interrupted in time (a revolution, a warlike conflict).

At language colloquial, an anomaly is something that results strange or weird : "Upon entering the house, the old man did not notice any anomaly: however, his wife's murderer had returned there to erase his traces", "The elections were held without anomalies", “It was an unprecedented tournament, with several anomalies: there were games suspended for incidents, athletes who refused to play for lack of payment and some matches were played without an audience”.

The term anomaly It is part of a rather particular group, in terms of its use, since it is not exclusive of cultured language, but neither is it appreciated in any conversation of everyday speech. We could say that it is more typical of technical fields, where certain professionals look for anomalies as part of their daily tasks to correct them before they cause major problems .

In the programming informatics, for example, it is common for the word to spontaneously arise in a talk anomaly, although it is a daily and informal exchange; Let's look at some example sentences: "And? Have you noticed any anomaly?", "I have looked at the code of the drawing and I have not seen any anomaly, so the problem must be related to memory management".
