The idea is that one can assign a value

*somehow*to basically any other divergent series; see the link for a more thorough explanation.

(But don't tell the calculus students! They already can't remember the harmonic series is divergent.)

And I usually think of the harmonic series as being "equal" to log n, although of course log n isn't a number. So I amend the folklore, somewhat facetiously: "there are no divergent series."
