32Finite geometry — A finite geometry is any geometric system that has only a finite number of points. Euclidean geometry, for example, is not finite, because a Euclidean line contains infinitely many points, in fact precisely the same number of points as there are… …

35Hurwitz's automorphisms theorem — In mathematics, Hurwitz s automorphisms theorem bounds the group of automorphisms, via orientation preserving conformal mappings, of a compact Riemann surface of genus g > 1, telling us that the order of the group of such automorphisms is bounded …
36Skeleton suit — A skeleton suit is an outfit of clothing for small boys, popular from about 1790 to 1830, consisting of a tight short or long sleeved coat or jacket buttoned to a pair of high waisted trousers. Skeleton suits are often described as one of the… …

38X-ray crystallography — can locate every atom in a zeolite, an aluminosilicate with many important applications, such as water purification. X ray crystallography is a method of determining the arrangement of atoms within a crystal, in which a beam of X rays strikes a… …
