   Thanks, Dave.  I don't know WHY this thread makes me so crazy --
   it really shouldn't -- but I just can't help it.  I know you're
   not deliberately trolling for an argument.

   Ok, maybe it's easier if we turn the original assertion around:

   What if I said that the DEFINITION of "infinite" is "the number
   of 9s you'd have to append to 0.9 in order to make that number
   equal to 1"?  Would that make sense?

   Perhaps you could look at it in this casual, common-sense way:

   If 0.999... APPROACHES 1 as the number of 9s APPROACHES infinity,
   then 0.999... EQUALS 1 when the number of 9s EQUALS infinity.

   Do either of those approaches help?

> It seems that it all hinges on what infinity means

   Well, yeah.

   Feynman hasn't been having trouble with ANY calculations since
   he died, and if Hawking could speak, I'm pretty sure he'd tell
   you that 0.999... is equal to 1.

> I'm not bothered that it causes me trouble.

   That's fine... But the fact that you have difficulty with the
   concept isn't a good reason to assert that mathematics is wrong.

   "Zero" has ALWAYS existed in mathematics: "If Julius has X
   apples, and he gives III to Brutus and VII to Biggus Dickus, how
   many apples remain?"

   It's just the "0" SYMBOL which hasn't always existed.

   That's an argument AGAINST your point of view, not for it.
