(physics) the instrument used in field emission microscopy

(physics) a technique that uses field emission of electrons or positive ions from the needle-shaped tip of an emitter to produce a magnified image of the emitter surface (showing each atom) on a fluorescent screen

(algebra) A vector space (over some field) with an additional binary operation, a vector-valued product between vectors, which is bilinear over vector addition and scalar multiplication. (N.B.: such bilinearity implies distributivity of the vector multiplication with respect to the vector addition, which means that such a vector space is also a ring.)
