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
Convex measure "μ" is the push-forward on "ν" under a linear or affine map and formula_8 is a convex function, where Convex measures also satisfy a zero-one law: if "G" is a measurable additive subgroup of the vector space "X" (i.e. a measurable linear subspace), then the inner measure of "G" under "μ", must be 0 or 1. (In the case that "μ" is a Radon measure, and hence inner regular, the measure "μ" and its inner measure coincide, so the "μ"-measure of "G" is then 0 or 1.)
