Interestingly, in this longer document the author gives more or less an actual definition of dyad which isnt the same as tensor product of two vectors, and with that definition the statement that every tensor is a. Scalars, vectors and tensors a scalar is a physical quantity that it represented by a dimensional number at a particular point in space and time. These representations are extremely useful as they are independent of the coordinate systems considered. A third vector product, the tensor product or dyadic product, is important in the analysis of tensors of order 2 or more. This new edition includes expanded derivations and solutions, and new applications. In mathematics, a tensor is an algebraic object that describes a multilinear relationship between sets of algebraic objects related to a vector space.
