This introductory article presents in a pictorial way the basic concepts of black hole’s theory, as well as a description of the astronomi...

Introduction to a general crystallography.

The definition of an extended crystallographic group is given, based on an n-dimensional Euclidean space, carrier of a faithful integral representation of a permutation group of atomic positions. The Euclidean crystallography of normal crystals and the higher-dimensional one applied to incommensurately modulated crystals, intergrowth crystals and quasicrystals are special cases of a general cry...
