Is tensor product the same as dyadic product of two vectors? And dyadic multiplication is just matrix multiplication? You have a column vector on the left and a row vector on the right and you just multiply them and that's it? We just create a matrix out of two vectors so we encode two different things, such a stress tensor in different directions? Sounds too simple to be true. I tried reading about the tensor product space and it was way too abstract and every source gives a different explanation.
