Point reflectionIn geometry, a point reflection or inversion in a point (or inversion through a point, or central inversion) is a type of isometry of Euclidean space. An object that is invariant under a point reflection is said to possess point symmetry; if it is invariant under point reflection through its center, it is said to possess central symmetry or to be centrally symmetric.
Point reflection can be classified as an affine transformation. Namely, it is an isometric involutive affine transformation, which has exactly one fixed point, which is the point of inversion. It is equivalent to a homothetic transformation with scale factor equal to -1. The point of inversion is also called homothetic center. Quoting: observation [ link to en.wikipedia.org] Homothetic centerIn geometry, a homothetic center (also called a center of similarity or a center of similitude) is a point from which at least two geometrically similar figures can be seen as a dilation/contraction of one another. If the center is external, the two figures are directly similar to one another; their angles have the same rotational sense. If the center is internal, the two figures are scaled mirror images of one another; their angles have the opposite sense Quoting: observation [ link to en.wikipedia.org] you see i don`t see any explanation of vortice in that which makes sense it takes the mind away from vortice and points to an outside something undefined causeing an inside effect that is defined it`s gods will from the invisible unknowable god belief projected through number to look real it seems Quoting: aether and it does look real until you know why it is not real because it models a real effect so it looks true
