**Defined in theory: Tensor-quantities****Source code: tensor-quantities.lisp**

**Documentation:**Every tensor has an associated spatial dimension and tensor order. Each tensor-quantity can be decomposed into scalar components for a given orthonormal basis of the proper dimension (except of . The physical-dimension of a scalar component of the tensor-quantity is equivalent to the physical-dimension of the tensor-quantity.
