Platonic

Plato

The adjective platonic is associated with the figure of the philosopher Plato.

Platonic is an adjective that comes from Platonicus , a term from the Latin language. It generally applies to love that develops from an ideal or imagination , without sexual intimacy.

Platonic love is impossible to concretize or materialize: that is why it remains something idyllic , which can never be achieved. The most traditional example of platonic love is that felt for a Hollywood figure or a music star. The person who feels this love is dazzled by the image they receive, through the media, of the famous person in question. This type of platonic love is usually based on physical appearance.

Illusion is what sustains the existence of platonic love. Since it cannot materialize, it remains valid from the subject's imagination. If said love were to materialize physically or develop in another way, it would no longer be considered platonic.

Plato and platonic love

It is important to note that the adjective platonic comes from Plato , one of the most important Greek philosophers of antiquity. For Plato , real love is that which is felt for knowledge. This means that love between two human beings arises from mutual discovery and getting to know each other.

In this way, it is easy to see that what we understand today as Platonic love is quite different from Plato 's own ideas about love. While in our conception the feeling is based on an ideal and fantasy, the love that Plato referred to required knowing the other person in depth.

convex polyhedron

A platonic solid is a convex polyhedron with particular characteristics.

a type of solid

A convex polyhedron is called a Platonic solid (that is, when joining any pair of the points that make it up, an internal segment is obtained) whose faces and solid angles are equal to each other. Its name, as you can imagine, was chosen in honor of Plato , who was the first to study it. This type of geometric figure is also known as a regular solid , Pythagorean solid , Platonic body , or Plato's polyhedron .

The list of Platonic solids is finite; More precisely, it is made up of five figures: the cube (also called regular hexahedron ), the tetrahedron, the icosahedron, the octahedron and the dodecahedron. There are several classifications for polyhedra , and this means that oneself can be known in different ways; According to the mathematician Norman Johnson , who in 1966 made public the list of all the solids he had identified, the octahedron is called a square dipyramid and the icosahedron is a gyro-elongated pentagonal dipyramid .

One of the properties of Platonic solids is regularity , which defines the following rules for constructing these figures:

  • All its faces must be regular polygons (its sides and interior angles are congruent with each other) equal.
  • The same number of edges and faces must occur at each of its vertices.
  • All its edges must measure the same.
  • All its dihedral angles (those calculated between two faces that share the same edge) must be equal.
  • Each of its vertices must be convex to those of the icosahedron.

On the other hand, there is symmetry:

  • The cube is the only Platonic solid whose center is also its center of symmetry.
  • They all have axial symmetry (all their half-planes resulting from dividing the figure with an axis have the same characteristics).
  • They all have mirror symmetry (the definition of symmetry used in everyday speech; it occurs when there is a point equivalent to each of those on one side of a plane of symmetry that cuts the figure into two parts).
