Which makes it all the more enigmatic. Simple things like '0', the
identity matrix, 'i', 'e', 'pi', can have profound implications but
by themselves seem anywhere from trivial to self-evident. Rather
than pontificate (bombasticate, wax reflectively) on my own
experiences/random-thoughts/free-associations, I'd be interested in
what others here might know of where the Kronecker Delta would be
likely applicable to the types of things many of us (might?) assume
Tom is interested in (application to big data, natural language
processing, etc. in the context of Journalism?)
