Phenomenon

Short description: Observable event

For other uses, see Phenomena (disambiguation) and Phenomenal (disambiguation).

The combustion of a match is an observable occurrence, or event, and therefore a phenomenon.

A phenomenon  (pl.: phenomena), sometimes spelled phaenomenon, is an observable event.[1] The term came into its modern philosophical usage through Immanuel Kant, who contrasted it with the noumenon, which cannot be directly observed. Kant was heavily influenced by Gottfried Wilhelm Leibniz in this part of his philosophy, in which phenomenon and noumenon serve as interrelated technical terms. Far predating this, the ancient Greek Pyrrhonist philosopher Sextus Empiricus also used phenomenon and noumenon as interrelated technical terms.

## Common usage

In popular usage, a phenomenon often refers to an extraordinary event. The term is most commonly used to refer to occurrences that at first defy explanation or baffle the observer. According to the Dictionary of Visual Discourse:[2]

> In ordinary language 'phenomenon/phenomena' refer to any occurrence worthy of note and investigation, typically an untoward or unusual event, person or fact that is of special significance or otherwise notable.

## Philosophy

In modern philosophical use, the term phenomena means things as they are experienced through the senses and processed by the mind as distinct from things in and of themselves (noumena). In his inaugural dissertation, titled On the Form and Principles of the Sensible and Intelligible World, Immanuel Kant (1770) theorizes that the human mind is restricted to the logical world and thus can only interpret and understand occurrences according to their physical appearances. He wrote that humans could infer only as much as their senses allowed, but not experience the actual object itself.[3] Thus, the term phenomenon refers to any incident deserving of inquiry and investigation, especially processes and events which are particularly unusual or of distinctive importance.[2]

## Science

A comparison between a candle flame on Earth (left) and in a microgravity environment, such as that found on the International Space Station (right).
The same burning phenomenon is observed, but different flame shape and colouring phenomena are also observed. Cloud chamber phenomena. Scientists use phenomena to refine some hypotheses and sometimes to disprove a theory. See also animated version.

In scientific usage, a phenomenon is any event that is observable, including the use of instrumentation to observe, record, or compile data. Especially in physics, the study of a phenomenon may be described as measurements related to matter, energy, or time, such as Isaac Newton's observations of the Moon's orbit and of gravity; or Galileo Galilei's observations of the motion of a pendulum.[4]

In natural sciences, a phenomenon is an observable happening or event. Often, this term is used without considering the causes of a particular event. Example of a physical phenomenon is an observable phenomenon of the lunar orbit or the phenomenon of oscillations of a pendulum.[4]

A mechanical phenomenon is a physical phenomenon associated with the equilibrium or motion of objects.[5] Some examples are Newton's cradle, engines, and double pendulums.

## Sociology

Group phenomena concern the behavior of a particular group of individual entities, usually organisms and most especially people. The behavior of individuals often changes in a group setting in various ways, and a group may have its own behaviors not possible for an individual because of the herd mentality.

Social phenomena apply especially to organisms and people in that subjective states are implicit in the term. Attitudes and events particular to a group may have effects beyond the group, and either be adapted by the larger society, or seen as aberrant, being punished or shunned.
