The definition: A spherical neighborhood of a point is itself open-a-Euclidean Space in one dimension is a finite interval-Euclidean in two dimensions is a circle and Euclidean in 3-Dimensions and spheres- The blog looks the sphere in Euclidean-Geometry, non-Euclidean geometry, like sphere in a sphere or hyperbole for example, using differential geometry, topology and algebraic topology

Invariant
Invariant is a property, held by a class of mathematical objects, which remains unchanged when transformation.
Transformation: is a function who maps to itself, in Euclidean geometry, move every point in the same direction or a constant vector for every point as shifting the origin of the coordinate system. The syetem can be rotate (sniping)
