length of a vector
31Foucault pendulum vector diagrams — Several vector diagrams are often used to demonstrate the physics underlying the Foucault pendulum. Diagrams are provided to illustrate a pendulum located at the North Pole, equator, and 45 degrees N to show how the rotation of Earth in relation… …
32Displacement (vector) — Displacement versus distance traveled along a path. A displacement is the shortest distance from the initial to the final position of a point P[1]. Thus, it is the length of an imaginary straight path, typically distinct from the path actually… …
33Burgers vector — The Burgers vector, often denoted by b, is a vector that represents the magnitude and direction of the lattice distortion of dislocation in a crystal lattice. [Callister, William D. Jr. Fundamentals of Materials Science and Engineering. John… …
34position vector — ▪ mechanics straight line having one end fixed to a body and the other end attached to a moving point and used to describe the position of the point relative to the body. As the point moves, the position vector will change in length or in… …
35Viral vector — Viral vectors are a tool commonly used by molecular biologists to deliver genetic material into cells. This process can be performed inside a living organism ( in vivo ) or in cell culture ( in vitro ). Viruses have evolved specialized molecular… …
36Dope vector — In computer programming, a dope vector is a data structure used to hold information about a data object,[1] e.g. an array, especially its memory layout. A dope vector typically contains information about the type of array element, rank of an… …
37Coordinate vector — In linear algebra, a coordinate vector is an explicit representation of a vector in an abstract vector space as an ordered list of numbers or, equivalently, as an element of the coordinate space Fn. Coordinate vectors allow calculations with… …
38Distance-vector routing protocol — In computer communication theory relating to packet switched networks, a distance vector routing protocol is one of the two major classes of routing protocols, the other major class being the link state protocol. Distance vector routing protocols …
39Persistence length — The persistence length is a basic mechanical property quantifying the stiffness of a long polymer.Informally, for pieces of the polymer that are shorter than the persistence length, the molecule behaves rather like a flexible elastic rod, while… …
40Dimension theorem for vector spaces — In mathematics, the dimension theorem for vector spaces states that all bases of a vector space have equally many elements. This number of elements may be finite, or given by an infinite cardinal number, and defines the dimension of the space.… …
