Position vector — A position, location or radius vector is a vector which represents the position of an object in space in relation to an arbitrary reference point. The concept applies to two or three dimensional space.Keller, F. J, Gettys, W. E. et al. (1993),… … Wikipedia
Orbital state vectors — In astrodynamics or celestial dynamics orbital state vectors (sometimes state vectors) are vectors of position ( ) and velocity ( ) that together with their time (epoch) ( ) uniquely determine the state of an orbiting body. State vectors are… … Wikipedia
Covariance and contravariance of vectors — For other uses of covariant or contravariant , see covariance and contravariance. In multilinear algebra and tensor analysis, covariance and contravariance describe how the quantitative description of certain geometric or physical entities… … Wikipedia
General position — In algebraic geometry, general position in a notion of genericity for a set of points, or other geometric objects. It means the general case situation, as opposed to some more special or coincidental cases that are possible. Its precise meaning… … Wikipedia
Euclidean vector — This article is about the vectors mainly used in physics and engineering to represent directed quantities. For mathematical vectors in general, see Vector (mathematics and physics). For other uses, see vector. Illustration of a vector … Wikipedia
Reciprocal lattice — In physics, the reciprocal lattice of a lattice (usually a Bravais lattice) is the lattice in which the Fourier transform of the spatial function of the original lattice (or direct lattice) is represented. This space is also known as momentum… … Wikipedia
Four-vector — In relativity, a four vector is a vector in a four dimensional real vector space, called Minkowski space. It differs from a vector in that it can be transformed by Lorentz transformations. The usage of the four vector name tacitly assumes that… … Wikipedia

Vectorial Mechanics — (1948) is a book on vector manipulation (i.e., vector methods) by Edward Arthur Milne, a highly decorated (e.g., James Scott Prize Lectureship) British astrophysicist and mathematician. Milne states that the text was due to conversations (circa… … Wikipedia
