Its all dense, so I think its less relevant. The sparse tensor stuff that
Edgar was experimenting
with is much more interesting. Sometimes I think Tensor-Train is
interesting, but that I recover.
Its looks like tensor stuff really could be useful for statistics problems,
but so far I am unconvinced
its useful for physics.

What most experimenters take for granted before they begin their
experiments is infinitely more interesting than any results to which their
experiments lead.
