Stilb (unit) meter. The current national standard for SI in the United States discourages the use of the stilb. formula_1 formula_2 formula_3 formula_4 formula_5 Other units of luminance: Stilb (unit) The stilb (sb) is the CGS unit of luminance for objects that are not self-luminous. It is equal to one candela per square centimeter or 10 nits (candelas per square meter). The name was coined by the French physicist André Blondel around 1920. It comes from the Greek word "stilbein" meaning "to glitter". It was in common use in Europe up to World War I. In North America self-explanatory terms such as
Borel measure following are equivalent: The Cramér–Wold theorem in measure theory states that a Borel probability measure on formula_26 is uniquely determined by the totality of its one-dimensional projections. It is used as a method for proving joint convergence results. The theorem is named after Harald Cramér and Herman Ole Andreas Wold. Borel measure In mathematics, specifically in measure theory, a Borel measure on a topological space is a measure that is defined on all open sets (and thus on all Borel sets). Some authors require additional restrictions on the measure, as described below. Let formula_1 be a locally compact Hausdorff space,
