Few people on this planet understand 'fully' the concepts of Tensor maths. I've read a fair deal about it/them and think I understand 'some' of it.

Few would even claim to understand it - and most of those - well......

Anyhow, back to the original post, there are a few good sites on the net that present tensor math at differing levels of difficulty..

Now ....if I could only get the concept of entanglement condensed down to a couple of paragraphs.
