The concept of phenomenon originates from the word latin phaenomĕnon, which in turn derives from a Greek concept. The word refers to any event that is present in the consciousness of a subject and which appears as the object of its perception.
Phenomenon is also something extraordinary and surprising, a monstrous animal and a remarkable person of its kind (for example, "Diego Maradona is a phenomenon"). Thus, the concept is also an adjective of the colloquial language.
In the philosophy of Immanuel Kant, on the other hand, is the subject matter of the sensitive experience. The non-phenomenique or perceptible is that Kant considers noumenon.
Among the phenomena in the physical sense, we will mention the physical phenomena (any observable natural event and which can be measured using a device or instrument, where the substances involved in general do not change; where they change, this change takes place at the subatomic level in the kernel of the stakeholders atoms) and chemical phenomena (the observable events that can be measured (, in which stakeholders substances change when they assemble), among others.
It is noted that paranormal phenomena are those that contradict the natural laws and which cannot be explained in current science. This class of phenomena cannot be explained only by a broad revision of the basic principles of science, because they are not compatible with the standard of perceptions, beliefs, and expectations concerning the reality.
