scalar
A scalar is a quantity that is invariant
under coordinate
transformation, also known as a tensor of rank 0. For example, the number 1 is a scalar, so is any number or variable . The point is not a scalar because it is variable under rotation
.
As such, a scalar can be an element of a field over which a vector space
is defined.
