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
Copy constructor — A copy constructor is a special constructor in the C++ programming language creating a new object as a copy of an existing object. The first argument of such a constructor is a reference to an object of the same type as is being constructed… … Wikipedia
Plain Old Data Structures — (PODS) are data structures that are represented only as passive collections of field values, without using encapsulation or other object oriented features.Plain Old Data Structures are appropriate when there is a part of a system where it should… … Wikipedia
Dot product — Scalar product redirects here. For the abstract scalar product, see Inner product space. For the operation on complex vector spaces, see Hermitian form. For the product of a vector and a scalar, see scalar multiplication. In mathematics, the dot… … Wikipedia
