Rima Ruhman, responding to Kim Roper's observation that "2+ 2 *does* equal 5
... for sufficiently large values of "2"., responded that <<With that
reasoning, 2+2 can almost equal 6. (5.99999998)>>

But of course. That's just a _very_ large value of 2. But if you wish, we
could name this "Rima's lemma"...

"Arthur C. Clarke had suggested that any sufficiently advanced technology
would be indistinguishable from magic--referring to a possible encounter
with an alien civilization--but if a science journalist had one
responsibility above all else, it was to keep Clarke's Law from applying to
human technology in human eyes."--Greg Egan, "Distress"
