A quantity having direction as well as magnitude, especially as determining the position of one point in space relative to another
A vector describing the position of a particle of matter, whose magnitude is the product of the mass of the particle and its distance from the origin.
A vector of which only the magnitude and direction are specified, not the position or line of action
A vector represented by a matrix consisting of a single row of elements
A vector which has a magnitude of one
A vector which changes sign when the signs of all its components are changed.
A line of variable length drawn from a fixed origin to a curve
A vector in a space whose dimensions correspond to all the independent wave functions of a system, the instantaneous value of the vector conveying all possible information about the state of the system at that instant
A function of a space whose value at each point is a vector quantity
A space consisting of vectors, together with the associative and commutative operation of addition of vectors, and the associative and distributive operation of multiplication of vectors by scalars
A DNA molecule (especially a plasmid) capable of replicating, which is modified such that a fragment of foreign DNA can be inserted into it and which can hence be used for cloning.
A vector which defines the position of a point relative to a fixed origin.
The vector product of the electric and magnetic field strengths at any point, which can often be interpreted as describing the magnitude and direction of the flow of electromagnetic energy.
The product of two real vectors in three dimensions which is itself a vector at right angles to both the original vectors. Its magnitude is the product of the magnitudes of the original vectors and the sine of the angle between their directions
A processor that is able to process sequences of data with a single instruction
