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

For instance: “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 tests worried the doctors “.

The idea of ​​anomaly appears in different contexts. In the field of biology, there is talk of genetic abnormality when a pathology causes a modification of the genome. 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 classical symmetry, such as being one of the Lagrangian that is broken 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 the conservation laws and the temporal evolution. Currently, it is the main operator to describe a physical system.

Speaking of quantum effects, we refer to the quantum mechanics, a part of physics that is responsible for describing nature in a fundamental way 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 regularized so that all symmetries are preserved at the same time, there is also an infrared effect, since the The character of these divergences is determined by low-energy physics.

The concept also appears in the astronomy, where it talks about:

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

* average anomaly: a portion of a period of the orbit, which is expressed in the form of 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.

AnomalyA social anomaly, on the other hand, it is a conduct or a habit that circumvents the conventional rules of the society. It can be a permanent anomaly, which is sustained even as time advances (such as an addiction), or a periodic anomaly, which is interrupted in time (a revolution, a war conflict).

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

The term anomaly it is part of a quite particular group, as far as its use is concerned, since it is not exclusive to the 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. problems.

In the programming computer science, for example, it is common for the word anomaly, even if 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 drawing code and I have not seen any anomaly, so the problem must be related to memory management”.
