There is no difference in my opinion.

For sqrt2 there is a sequence 
1.
1.4
1.41
1.414
...
approaching but never reaching the limit
1.414...

This limit can be calculated to every desired precision. But it cannot be expressed by fractions (digits) - not even by infinitely many.

In Cantor's diagonal argument we can prove that every entry differs from the diagonal number constructed up to that entry. But in order to obtain the complete diagonal number, we would need an actually infinite, uninterrupted sequence of digits that represent the diagonal number. That is impossible because a real number defined by a digit sequence would have to be fixed, i.e., it would need a last digit. 

In the Binary Tree we have the atomic structure 
 |
/ \
Every sequence of such structures is bounded by less than aleph_0 paths. In order to get a limit of uncountably many paths, we would need a gap. Contradiction.

I do not. Above I answered Zelos who denied that finite cases have any effect on infinite. I showed him that this is incorrect and would destroy Cantor's diagonal argument.

I accept only those infinite results which are compatible with the finite terms of a corresponding sequence - in all cases. I accept that the antidiagonal is not in Cantor's list, but I do not accept that it ever completes the defintion of a real number.

But why exactly is there a difference here?
Forget what Zelos Malum says, explain why *you* treat the two cases
differently.
(Simply saying that one is mathematics, and the other is not,
does not provide an explanation.)

"Everybody accepts" is not a reason for WM to accept.

In one case you say that the presence of infinitely many unexamined
cases blocks a proof, in the other you ignore the problem.
Logic requires you to explain this divergence.

Double standards!!

It doesn't, it at no point argues from the finite, the infinite.

>No. The infinite of mathematics can be determined from the finite. The sequence of (nodes - paths) 0, 0, 0, ... cannot have another limit than 0. 

Not studied much topology I take it? It can have non-zero limits and even have multiple limits.

>Because it is based on mathematics. If Zelos Malum was right, the proof would not hold "in the limit".

At what step does it arguefrom the finite the infinite?

>As I said above: An infinite sequence cannot define a real number. 

Considering real numbesr can be constructed from cauchy sequences of rational numbers, you are simply wrong.

>I do not. Above I answered Zelos who denied that finite cases have any effect on infinite. I showed him that this is incorrect and would destroy Cantor's diagonal argument. 

It woudln't cause it at no point argues a finite case. You got an infinite list of ifninite decimals and get a new infinite decimal number that. Never ifnite

>I accept only those infinite results which are compatible with the finite terms of a corresponding sequence - in all cases. I accept that the antidiagonal is not in Cantor's list, but I do not accept that it ever completes the defintion of a real number. 

That arguemenet however is selfcontradictory.

The diagonal number is infinite. But only its finite parts are available.

Most of topology is nonsense.

The diagonal number: Only digits at finite positions in finite lines are available. But you argue that the infinite sequence is not in the infinite list.

Every bijection: Only pairs (like n, q) at finite positions are available. You argue that all elements can be paired.

What measurement should "The diagonal number 
is infinite. But only its finite parts 
are available." be?

Take your other example 2) alle Endsegments are
infinite and 1) there is no number in all Endsegments. 
This is true if inifnite is infinite:

                             n
   E_1   : ******************|*******...
   E_2   : o*****************|*******...
   E_3   : oo****************|*******...
   E_4   : ooo***************|*******...
   ...
   E_m   : oooooooooooooooooo|o******...
   E_m+1 : oooooooooooooooooo|oo*****...
   ... 

Are both true if infinite is not infinite?
Lets say, infinite means collection of finite,
a kind of modal logic with multiple possible

worlds. Then a possible world would be:

Possible World 1:

   E_1   : ***************
   E_2   : o**************
   E_3   : oo*************
   E_4   : ooo************
   ...
   E_k-2 : ooooooooooooo**
   E_k-1 : oooooooooooooo*

infinite. A further question is when we have

some n, what worlds are reachable. Is it
possible that we have n, with no E_m, such

Looks compared to FOL+ZFC, it could result in
an extremly complex formalization of Muckamatics,
with a lot of decisions that need to be made,

to get a coherent model of Muckamatics. Mostlikely
the simplest attempt already yields to some inconsistency
that is not found in FOL+ZFC, but is part of the

problem of the immature Muckamatics. All these 
inconsistencies are problems of Muckamatics, which 
only Prof Mucke Funk can heal, if this is at all 

possible. Maybe its sympthom of a broken mind, without 
some systematics and cannot be healed. If there is no 
axiom system so far, there might be 

also none in the future, even not in 3000 years.

No, all of it is because agian "available" isn't a defined predicate.

You not understanding it does not make it nonsense

Yes but then again I don't argue in strict mathematics. I grab it whole way infinite.

Not at all, you assume only finite.

That doesn't change but that doesn't mean there are ONLY countably many cause you assume what is finite extends to infinite.

Do you believe that "in the infinite" more than two lines can arise from one node or split-point?

Because it hasn't, ZFC is not known to have any contradictions, that is why it stands to this day.

aleph_0 and any set with that cardinality is the smallest and yes, |N is such.

Tehre is no infinitTH level but there are infinitely many levels so paths spanning all of them are is uncountable and that is not a contradiction.

No it doesn't you blabbering buffoon.

|N \ {1, 2, 3, ..., n}

is NON-EMPTY!

Not a contradiction in set theory though cause it doesn't state at any finite level, there is aleph_1 paths.

There is no infinite level. Nodes are existing only at finite levels. What are paths if not sequences of nodes at finite levels?

You would think that a single element could be sufficient to make

I know that the set |N \ {1, 2, 3, ..., n} is said to be infinite for every n in |N. That shows that even sets without elements can be infinite.

There is no mathematical induction of the
form from natural numbers to the set of natural numbers.
This is NOT mathematical induction:

   /* no such mathematical induction schema,
      an invention by WM */

   0 in M
   forall n(n in M => n+1 in M) 
   -----------------------------
   |N in M

You are highly confused and halucinating. The mathematical
induction only says:

   /* the usual mathematical induction */

   0 in M
   forall n(n in M => n+1 in M) 
   -----------------------------
   forall m(m in M)

For example, we can use the above induction schema to
prove that [n,omega) your "final" segments are all infinite.
Here is a proof:

Proof: Inducton base: [0,omega) is infinite by definition.
Induction step. We have already by induction hypothesis
that [n,omega) is infinite, now how about [n+1,omega) is
it also infinite. Yes, we can find a bijection f : [n+1,omega) ->
[n,omega), where f(x) = x - 1.

Q.E.D.

So all that we have proved is that for every n, [n,omega) is
infinite. But thats where mathematics stops. There is no
further induction step, that would then deduce that

[omega,omega) = {} would be infinite. Which induction schema
should this be? Even transfinite induction cannot do that.
Thats just nonsense.

For to apply transfinite induction we would need to have
apply the following induction schema, this is transfinite
induction up to omega+1:

   /* this would be transfinite induction 
      up to omega+1, i.e. for domain omega+1 */

   0 in M
   forall a(a<omega & a in M => a+1 in M) 
   forall a(a<omega & a in M) => omega in M
   ----------------------------------------
   forall a(a in M)

How would this show that? Again there is no 
induction of a predication "infinite" by the 
following schema:

   /* no such mathematical induction schema,
      an invention by WM */

   0 in M
   forall n(n in M => n+1 in M)
   -----------------------------
   |N in M 

or you can also write it as follows, using |N = ∪n, namely
the fact that |N can be view as an infinite union:

   /* no such mathematical induction schema,
      an invention by WM */

   0 in M
   forall n(n in M => n+1 in M)
   -----------------------------
   ∪n in M 

Similarly for infinite intersection. You cannot
use mathematical deduction, for omega as in PA, 
to deduce properties of an infinite intersection 

as a **whole**. In a prove of

    ∩ [n,omega] = ∅

We prove something about the elements of the
infinite intersection, and since there are no
such elements, we know the result is empty.

The mathematical induction schema goes from
zero element and successor elements to forall 
elements, but not to some complete set.

Even using some element to set bijection
like n <-> [0,..,n-1}, this doesn't give you
your Mückenheimerisches Induktions Axiom...

WM = la mouche dans la bouteille

You need to get to the next level, for example
whats a variable in mathematics...

La philosophie est un combat contre l'ensorcellement 
de notre entendement par les ressources de notre 
langage. Son but est de montrer à la mouche l'issue 
par où s'échapper de la bouteille à mouches. Elle 
conduit à la découverte de quelque pur non-sens où 
l'entendement se fait des bosses en courant à l'assaut 
des frontières du langage. Le monde est mesuré par 
le langage, dont les limites sont logiquement 
énonçables ; on ne peut que montrer l'indicible et 
le secret. La philosophie n'est pas à une doctrine, 
c'est une activité. Elle n'est pas une fin en soi, 
mais un instrument qui aide à comprendre les limites 
du langage, qui sont comme une bouteille à mouches. 
Elle montre l'issue ; une fois sortie de la bouteille 
à mouches, la philosophie ne sert plus à rien.

Good. For once you are correct. (As are those who say it.)

Back to the usual being wrong. The empty set (the only set without 
elements) is not infinite.
