scalar
single field element, e.g. real number, in the context of linear algebra
directional derivative
instantaneous rate of change of the function
pseudoscalar
In linear algebra, a pseudoscalar is a quantity that behaves like a scalar, except that it changes sign under a parity inversion while a true scalar does not.
Lorentz scalar
quantity in the theory of relativity which is invariant under a Lorentz transformation
