WebJun 14, 2024 · Crystallographic groups (also: “space groups”) are symmetry groupsof crystals. The use of crystallographic groups for the study of crystals(e.g. Hilton 1903, Engel 1986) is much in the spirit of Klein geometry/the Erlanger program(see for instance Weyl 1938; Grünbaum & Shephard 2010).

WebSep 26, 2024 · What is X-ray crystallography? X-ray crystallography is a scientific field concerned with revealing the structure of matter at the atomic level. The essential method involves exposing a crystallised sample of a molecule to x-rays, usually with an instrument called an x-ray camera. Webrepetition, it is only necessary to describe the arrangement of the atoms in the group that is repeated, and then to describe how the repetition takes place. Let us begin with a discussion of the ways in which repetition can take place. For this discussion, we can replace the (probably) large number of atoms in the repeating group with a point.
