The dimension of a vector space is the number of vectors in the smallest spanning set. A set of vectors that can generate every vector in the space through such linear combinations is known as a spanning set. Peano called his vector spaces “linear systems” because he correctly saw that one can obtain any vector in the space from a linear combination of finitely many vectors and scalars- av + bw + … + cz. Vector spaces as abstract algebraic entities were first defined by the Italian mathematician Giuseppe Peano in 1888. The idea of a vector space developed from the notion of ordinary two- and three-dimensional spaces as collections of vectors. Vector spaces are fundamental to linear algebra and appear throughout mathematics and physics. Vector space, a set of multidimensional quantities, known as vectors, together with a set of one-dimensional quantities, known as scalars, such that vectors can be added together and vectors can be multiplied by scalars while preserving the ordinary arithmetic properties (associativity, commutativity, distributivity, and so forth).
