Concept in Definition ABC

Translation or translation is a term that refers to the movement and to change. It is a concept directly related to several scientific disciplines. In fact, there is translation in the geometry, in physics or in relation to the movements of the Earth.

The translation of the Earth

As we all know, the Earth performs two types of movements: it moves on itself and makes another movement around the Sun. The first is known as the rotational movement and the second is the translational movement.

At the same time that our planet rotates on itself, it also rotates around the Sun. It takes the Earth a full year to go around the Sun. This implies that the translational movement is what gives rise to the different seasons of the year, while the rotational movement is what produces the change between night and day.

In the translational movement, the path that the Earth travels around the Sun is known as Earth's orbit and during this period of time the four seasons develop (the

spring runs from March 21 to June 20, the summer runs between June 21 and September 21, the fall runs from September 22 to December 21 and winter occurs between December 22 and March 20).

If we divide the Earth's orbit into two axes, each of them corresponds to two solstices, the summer solstice and the winter solstice (in the first day of the summer solstice occurs the longest day of the year and the first day of the winter solstice occurs the longest night long).

Translation in geometry

When we slide a geometric figure in a straight line, a translation occurs, that is, the position of a figure changes but not its size or shape. A translation has, therefore, the following elements: the sense, the magnitude and the direction.

The meaning refers to the movement can be to the right, left, up or down. Magnitude refers to the distance that runs through a geometric figure. Direction refers to horizontal or vertical movement.

Other senses of translation

In the sphere of math there is the translation of complex numbers. On the other hand, any planet has its own translational movements (the Earth, the Moon and the Sun). The idea of ​​translation also serves to express the app from a model of something to another context (for example, the translation of the Argentine soccer model to English soccer).
