Why should there be a separate topic for discussing things like that?

   What does the phrase, "this rathole is going down a rathole," really
   mean?
   
   Does it apply here?
   
   Given that this is the Age of Information, are packrats those lucky
   folks who manage to climb out of ratholes with useful information?

*If* a rathole is "an endless discussion on a small detail, causing the initial
argument to be forgotten", then it's quite clear what your sentence means. It
means that someone will start nit-picking on my definition :-)
   
>   Does it apply here?
I leave that to the interested noter.

Are you trying to confuse us with small details? ;-)

    re: .3
    
    I interpret that to mean that, not only has the note gone into the
    form of tangential nitpicking that has been defined as a rathole,
    that rathole has gone into a form of sub-rathole.

672.6meta-ratholesEAGLE1::EGGERSAnybody can fly with an engine.Fri May 26 1989 05:382
    The last several notes discuss the twists and turns (ie, ratholes) this
    subject on ratholes has taken. That makes these notes meta-ratholes. 
672.7pass the cheeseMARVIN::MACHINFri May 26 1989 11:258
    I disagree. There's no such thing as a 'meta-rathole', since that 
    presupposes you're out of the rathole while you're talking about it,
    which clearly we're not. The last few notes *are* the twists and turns
    of a rathole, as is this one and as we can justifiably expect the next
    one to be. There's no way out of this one, other than the route .0 has
    taken -- stand back and watch the rats.

     You're wrong.  This reply is anything but a rathole.
     Indeed, it pertains only to the discussion of this topic.

672.10Klein bottleEAGLE1::EGGERSAnybody can fly with an engine.Sun May 28 1989 05:334
    Re: .7
    
    Maybe calling the topic a "meta-rathole" is just recognizing that the
    hole is really a klein bottle, and we've been outside all along. 
672.11ebbing thoughts...PH4VAX::MCBRIDEI'm younger than that now.Tue May 30 1989 16:267
    if 2 x 2 = 2 squared then isn't a ratholed rathole = rathole squared?
    
    They don't get to be meta ratholes until they reach the 6th power.
    
    Remember, Bonnie, that teenagers are learning to be independant
    and part of that is making us desire for them to leave us or, at
    least, leave us alone.
672.12ratholes == <infinity>KAOFS::S_BROOKHere today and here again tomorrowTue May 30 1989 17:5516
    A rathole is like infinity
    
    add anything to it and it stays the same
    (1 + <infinity> = <infinity>)
    
    Multiply it by anything and it stays the same
    <infinity> * 2 = <infinity> 
    
    Divide it by anything and it stays the same
    <infinity> / 2 = <infinity> 
    
    Subtract anything from it and it remains the same
    <infinity> - 1 = <infinity>

    Re .12: Cantor proved that there at least two different infinities
    if I recall from my student days.

    re .14: 
    
    Let me guess -- a teeny weeny one and a real thumper of an infinity.
    I think Pascal had something to say about this, too.

672.16Diagonalization?CIROCC::treeseWin Treese, Cambridge Research LabThu Jun 01 1989 19:329
It seems to me that a rathole, as described in .12, corresponds to a countably
infinite set, because each item of the rathole (say, spoken comment)
can be put into correspondence with an integer.

However, one can imagine that a truly deep rathole may be uncountable.  I
have found a truly wonderful proof of this which this note is too small to
contain...

672.17spam,spam,spam,spam, and ratholeCOOKIE::DEVINEBob Devine, CXNThu Jun 01 1989 20:087
    Hmm sounds like we are discovering the mathematics of ratholes.
    Taking a tip from Whitehead, can we form a set of all ratholes
    that are themselves not ratholes?  For does not every rathole
    contain the seeds of another rathole?
    
    Is this note a divergence from the main discussion of ratholes?
    Or am I merely trying to end every line with the word "rathole"?
672.18DeMorgan's TheoremDDIF::CANTORThe answer is -- a daily double.Fri Jun 02 1989 06:299
Re .14

Georg Cantor proved that there were an infinite number of infinities,
didn't he?

(As far as I know, I am not related to old Georg, but that's a
discussion for a different rathole.)

672.19Ratholes revisitedMARVIN::MACHINFri Jun 02 1989 15:5212
    
    Proving that there is an infinite number of infinities, if infinity 
    is itself a theory, just proves there's an infinite number of theories,
    dosen't it?
    
    And if this is the case, claiming any one of them to be in any way
    'true' or better 'proved' suggests that the rest -- still and infinite
    number of them, of course -- are ratholes!
    
    Back to the topic! Does this mean this note should be moved by the mod?

>   Back to the topic! Does this mean this note should be moved by the mod?
   
   
   But then the moderator would have to declare the discussion on infinities
   a rathole and move the discussion to the rathole note.  Which is where it
   is already!  
   
   It could be said that recursion is also an infinity whose elements do
   not vary from each other.   So if this is a recursive (hence, infinite)
   discussion, as most ratholes are, then all these replies are really alike!

   
   							Terza
   
   P.S.- Then again, there are recurring sets of elements, where each
   set can be treated as an element in the aforementioned definition.
   The best example I know of is our very own word association note!
   
672.21YAR -- Yet Another RatholeTERZA::ZANEshadow jugglerFri Jun 02 1989 16:1311
   By the way, calling a discussion a rathole because it is either recursive
   or infinite is an almost always useless way to make the discussion
   finite and not a rathole.
   
   So what other things exist that become their opposites as soon as
   they are named?

672.23KAOFS::S_BROOKHere today and here again tomorrowFri Jun 02 1989 21:3710
    ratholes don't become finite when they are named .....
    
    calling them ratholes declares our boredom with arguing about
    infinities that we cannot make finite.  So we then leave them alone.
    It is possible to continue a rathole from where it left off into
    infinities.  A non-rathole, while it can be picked up again will
    develop either into a finite discussion or a rathole by the same
    means a new topic can.

    Maybe he only described three of them, but in fact there are an
    infinite number of infinities.
    
    The question is, WHICH infinity is the exact infinite number of
    infinities?

    It's obvious. The LAST infinity.
