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).
Web34 rows · In crystallography, a crystallographic point group is a set of symmetry operations, corresponding to one of the point groups in three dimensions, such that each operation (perhaps followed by a translation) would leave the structure of a crystal unchanged i.e. the same kinds of atoms would be placed in similar positions as before … WebCrystallographers often explicitly state the type of beam used, as in the terms X-ray crystallography, neutron diffraction and electron diffraction. These three types of radiation interact with the specimen in different ways. X-rays interact with the spatial distribution of electrons in the sample.
