https://en.wikipedia.org/wiki/Scalar_(mathematics)A scalar is an element of a field which is used to define a vector space. A quantity described by multiple scalars, such as having both direction and magnitude, is called a vector. In linear algebra, real numbers or generally elements of a field are called scalars and relate to vectors in an associated

A vector space is defined as a set of vectors (additive abelian group), a set of scalars (field), and a scalar multiplication operation that takes a scalar k and a vector v to another vector kv. For example, in a...

https://simple.wikipedia.org/wiki/ScalarIn mathematics, scalars are distinguished from more complex mathematical objects such as vectors and matrices in that they consist of only one number. A scalar k {\displaystyle k} can also be multiplied to a vector v {\displaystyle \mathbf {v} } or a matrix A {\displaystyle A} , resulting in the vector k v {\displaystyle k\mathbf {v} } and the ...

https://en.wikipedia.org/wiki/ScalarScalar may refer to:
• Scalar (mathematics), an element of a field, which is used to define a vector space, usually the field of real numbers
• Scalar (physics), a physical quantity that can be described by a single element of a number field such as a real numberWikipedia · Nội dung trong CC-BY-SA giấy phépScalar - Encyclopedia of Mathematics
https://encyclopediaofmath.org/wiki/ScalarThe term "scalar" comes from the original meaning as a quantity which can be completely specified by one (real) number. A scalar field on a manifold $ M $ is a function on $ M $; that is, a scalar field, or field of scalars, is a tensor field (cf. Tensor bundle) of rank $ ( 0, 0) $. These are the scalars in the algebra of tensor fields on $ M ...
