Scalar

- Scalar (mathematics) In linear algebra, real numbers are called scalars and relate to vectors in a vector space through the operation of scalar multiplication, in which a vector can be multiplied by a number to produce another vector, a quantity used to multiply vectors in the context of vector spaces
- Scalar (physics) In physics, a scalar is a simple physical quantity that is not changed by coordinate system rotations or translations , or by Lorentz transformations or space-time translations (in relativity). (Contrast to vector.), a quantity which is independent of specific classes of coordinate systems
- 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 type of a scalar variable. For example, char, int, float, and double are the most common scalar data types, an atomic quantity that can hold only one value at a time

- Scalar field In mathematics and physics, a scalar field associates a scalar value to every point in a space. The scalar may either be a mathematical number, or a physical quantity. Scalar fields are required to be coordinate-independent, meaning that any two observers using the same units will agree on the value of the scalar field at the same point in space
- Scalar multiplication In mathematics, scalar multiplication is one of the basic operations defining a vector space in linear algebra . In an intuitive geometrical context, scalar multiplication of a real Euclidean vector by a positive real number multiplies the magnitude of the vector without changing its direction. The term "scalar" itself derives from this

- Scalar product, also known as the dot product In mathematics, the dot product is an algebraic operation that takes two equal-length sequences of numbers and returns a single number obtained by multiplying corresponding entries and adding up those products. The name is derived from the centered dot "ยท" that is often used to designate this operation; the alternative name scalar
- Pseudoscalar
- Scalar processor Scalar processors represent the simplest class of computer processors. A scalar processor processes one data item at a time . In a vector processor, by contrast, a single instruction operates simultaneously on multiple data items. The difference is analogous to the difference between scalar and vector arithmetic
- Pterophyllum scalare Pterophyllum is a small genus of freshwater fish from the family Cichlidae known to most aquarists as "Angelfish". All Pterophyllum species originate from the Amazon River, Orinoco River and Essequibo River basins in tropical South America. The three species of Pterophyllum are unusually shaped for cichlids being greatly laterally (Lichtenstein, 1823), a species of freshwater angelfish
