The word fluctuation It is used in various contexts and areas when you want to express a situation dominated by oscillation and change.
In the field of physical one speaks of fluctuation when there is a time variation of a system. Now, if the phenomenon in question is characterized by repeating itself, we will speak of periodic oscillation. Oscillation, fluctuation, is represented in this area by a repeated movement that goes from one side to the other in relation to a central or equilibrium position. Meanwhile, this route of going from one side to the other, returning to the first side and after having passed through the central point twice, will be called a cycle.
For its part, quantum fluctuation it will involve a time shift in the amount of energy a point has in space. This is explained from uncertainty principlee, timely enunciated by the German-born physicist Werner Karl Heisenberg, and that maintains that it is impossible for some pairs of physical quantities to be known with arbitrary precision, such is the case of linear momentum and the position of an object. In other words, the more rigorous we seek when determining the position of a particle, the less we will know about its linear motion and speed. The aforementioned principle was essential when developing the Quantum theory.
On the other hand, when we are in the context of the economy and finance and there is talk of fluctuation, it will be referring to the loss of value of a certain currency and that originates as a result of the reduction in the possession of merchandise, or failing that due to the update that is carried out in the stock. In other words, it is the difference between the physical existence of the goods and what the inventory books express. And then that difference is what causes the fluctuation, the loss of money, that is, in reality I have these three devices but in the books it says that I have ten.
Terms such as change, alteration and variation.
