The term Magnitude is basically the description of a size, but it is mostly related to a large size, something with characteristics considerable enough to speak of the magnitude of an element, problem, situation, tragedy, cost, insanity or whatever.. The term is used in fields of engineering and the study of mathematics widely. For example, in physics, magnitude is the property of bodies with which the sizes and standards of space (height, surface, weight, time, temperature, length are measured and determined. This study is based on a previously established data table It contains standard measures with which it compares the size of the current product with the "original", that is, standard measure.
The physical quantities are classified into three: scalars, vector and tensor, the scalars are those that have values independent of the observer, such as mass, energy, density or temperature, they do not have direction or sense. The vectors depend on the observer and have direction and sense, for example, force, velocity or acceleration. The tensorials vary according to the observer, and their numbers change according to the chosen coordinate system.
It was in ancient Greece when they began to talk about Magnitudes, the astronomers of that time began to classify the stars according to the magnitude of their brightness, from there, if a scale of magnitudes in which the studies were understood Based on Greece, currently other standards are taken into account for this type of study, since technology has advanced in such a way that greater characteristics of a star can be determined millions light years from the earth.
