WebCrystallography is the study of the arrangement of atoms in solids that are mostly in three dimensional pattern. [1] Before the development of X-ray crystallography, the study of crystals was based on their geometry. This involves measuring the angles of crystal faces, and establishing the symmetry of the crystal in question. http://www.archive.bridgesmathart.org/2013/bridges2013-225.pdf
