The M-W definition is pretty meanigless, IMHO. I think it was put
there by someone who does not understand it.

While there are many ways that people may look at tensors,
I am partial to the one that defines vectors (which are really
rank 1 tensors!) and tensors in terms of their transformation

Another fallacy that I have come acorss is "a tensor is nothing
but a matix".
