In the natural sciences, a vector quantity (also known as a vector physical quantity, physical vector, or simply vector) is a vector-valued physical quantity. [9] [10] It is typically formulated as the product of a unit of measurement and a vector numerical value (), often a Euclidean vector with magnitude and direction.
In mathematics, vector algebra may mean: The operations of vector addition and scalar multiplication of a vector space; The algebraic operations in vector calculus (vector analysis) – including the dot and cross products of 3-dimensional Euclidean space
The cross-hatched plane is the linear span of u and v in both R 2 and R 3, here shown in perspective.. In mathematics, the linear span (also called the linear hull [1] or just span) of a set of elements of a vector space is the smallest linear subspace of that contains .
In linear algebra, the outer product of two coordinate vectors is the matrix whose entries are all products of an element in the first vector with an element in the second vector.
An operator is a function over a space of physical states onto another space of states. The simplest example of the utility of operators is the study of symmetry (which makes the concept of a group useful in this context).
In functional analysis, a branch of mathematics, an operator algebra is an algebra of continuous linear operators on a topological vector space, with the multiplication given by the composition of mappings.
In computer science, a 4D vector is a 4-component vector data type.Uses include homogeneous coordinates for 3-dimensional space in computer graphics, and red green blue alpha values for bitmap images with a color and alpha channel (as such they are widely used in computer graphics).
Yohanes Surya (born 6 November 1963) is an Indonesian physicist and coach of Indonesian Physics Team for the Olympiad (TOFI) since 1993. [1] Under his guidance, the Indonesian team has won 54 gold medals, 33 silver medals, and 42 bronze medals at various international science and physics competitions. [1]
