[warning sub-operational]

what's cool is that andre found that there

is some natural `tiering' of ASes just according

to (almost any topological) quantitative connectivity metrics

(math-heavy, no ASes identified, just illustrates that

tiering has some sense manifested in real data,

which i think is pretty cool)

.... To be sure, mathematics can be extended to

any branch of knowledge, including economics,

provided the concepts are so clearly defined

as to permit accurate symbolic representation.

That is only another way of saying that in some

branches of discourse it is desirable to know

what you are talking about.

-- James R. Newman, World of Mathematics, 1956
