From Latin fluctuation, the fluctuation it is the act and the consequences of fluctuate . This verb refers to the oscillation (increase and decrease alternately) or to hesitate . The concept has different applications according to context .
In the field of finance , the fluctuation is the monetary loss which is produced by the reduction of a certain quantity of merchandise or by the update of the stock. It's about the difference between what the inventory books reflect and the real (physical) existence of the goods .
It is known as decrease to the concrete and material loss of the products, while the fluctuation is linked to the monetary loss due to said variation. The fluctuation reflects in money, therefore, the difference between what you have and what you should have according to the inventories.
It is possible to distinguish two major types of fluctuations. The regular fluctuation , also known as cyclic fluctuation , occurs when there are seasonal periods (growth stages are followed by periods of contraction). The irregular fluctuation On the other hand, it is determined by modifications that are not periodic and that are due to alterations that are not usual.
The changes in the currency market They are also known as fluctuations. The concept, in this case, allows naming changes in the value of one currency compared to another or others. This fluctuation usually depends on the central banks of each country, on the political actions and on the current state of international trade.
In the same way that the term fluctuation is used in what is the economic and business field, it is also used in the Physics sector. In this case, the concept at hand can be defined as the difference between what is the normal value of a quantity and its instantaneous value.
In addition to that new meaning, the word we are addressing is also part of a broader term known as the quantum fluctuation that refers to the change in energy that occurs at a particular point in space and at a time determined and temporarily.
This last concept must be said to be closely linked to what is the uncertainty principle, also known as Heisenberg's relationship of indeterminacy. In the year 1927 it was when the German physicist who gives it its name proceeded to formulate the one with which it becomes clear that it is impossible to simultaneously measure what the linear momentum and the position of a particle are.
This principle must be stressed that it has become one of the basic pillars of quantum theory. So much so that he, and in particular his cited formulator, won the Nobel Prize in Physics in 1932.
Nor should we forget that fluctuation is a concept that is used to define the movement that a body experiences to the beat of what the waves are.
It is known as fluctuation, finally, the hesitation that leads to a person hesitating and not resolving a situation.
