Multivariable calculus 1.4 - Dyadic product and tensors of rank 2

Описание: This video is an introduction to the third way of multiplying vectors, which is the dyadic product. It also serves as a small introductions to tensors of rank 2.
This video will use the matrix notation for tensors, but as it is an introduction, I will not covers concepts, such as co-variance and contra-variance, and here, all vectors are considered equal.
I will not go that deep into tensors of rank 2, but we will come in contact with them later when we calculate the gradient of vectors, and we do have them in fluid mechanics
