• Scalar-tensor theory — Scalar tensor theories are theories that include a scalar field as well as a tensor field to represent an interaction, especially the gravitational one. Tensor fields and field theory Modern physics tries to derive all physical theories from as… …   Wikipedia

• Scalar field theory — In theoretical physics, scalar field theory can refer to a classical or quantum theory of scalar fields. A field which is invariant under any Lorentz transformation is called a scalar , in contrast to a vector or tensor field. The quanta of the… …   Wikipedia

• Scalar (computing) — In computing, a scalar is a variable or field that can hold only one value at a time; as opposed to composite variables like array, list, record, etc. In some contexts, a scalar value may be understood to be numeric. A scalar data type is the… …   Wikipedia

• Scalar potential — A scalar potential is a fundamental concept in vector analysis and physics (the adjective scalar is frequently omitted if there is no danger of confusion with vector potential). Given a vector field F, its scalar potential V is a scalar field… …   Wikipedia

• Weyl scalar — In General Relativity, the Weyl scalars are a set of five complex scalar quantities, :Psi 0, ldots, Psi 4, describing the curvature of a four dimensional spacetime. They are the expression of the ten independent degrees of freedom of the Weyl… …   Wikipedia

• Nullable type — In programming, nullable types are a feature of some statically typed programming languages which allows a data type to be set to the special value NULL instead of their common range of possible values. For value types or built in data types like …   Wikipedia

• System of linear equations — In mathematics, a system of linear equations (or linear system) is a collection of linear equations involving the same set of variables. For example,:egin{alignat}{7}3x ; + ; 2y ; ; z ; = ; 1 2x ; ; 2y ; + ; 4z ; = ; 2 x ; + ; frac{1}{2} y ; ; z …   Wikipedia
