A fun summation:

10^(-0) + 10^(-2) + 10^(-4) + 10^(-6) + ...

1.0101010101...

or:

10^(-0)*1 + 10^(-2)*2 + 10^(-4)*3 + 10^(-6)*4 + ...

You just can't see the holes, because you close your eyes.

You seem to think that unbounded sets have there bounds in them.

You assume that your NUF exists, and that assumption requires that there
be a "first" (lowest) Unit Fraction which exists.

Since, no such number can exist, as if x is a unit fraction x/2 will be
too, and will be lower than it, you logic is fallacious.

So, your assumptions are incompatible with the definition of the Natural
Numbers, so make your system inconsistent, and thus worthless.

NOT well defined.

Your assumptions that define it are inconsistant with the definition of
Natural Numbers.

Your NUF(x) has an output range that is outside the range of the Natual
Numbers, and thus not "Well Defined" on that set (or the rationals, or
the Reals).

So, all you are showing is that you don't understand what a "well
defined" function means.

It is easy to create a word salad that seems to fully define a function,
that actually described a not possible to exist thing, and your above is
just one example of that.

The iota-values the range of the "natural/unit equivalency function",
not-a-real-function, in the usual and standard sense of the word,
but standardly modeled by real functions, as a continuum limit,
are rather well-defined.

Will he ever learn?

One of these claim must be given up:

| exists
or
| a skipping.function isn't all.continuous
or

Suppose we accept the second and third claims.

Then, the existence of
a final.ordinal.reciprocal.free zone (0,δ)
is contradictory.

With
a final.ordinal.reciprocal.free zone (0,δ)
and the second claim,
we must also have a maximal
final.ordinal.reciprocal.free zone (0,β) or (0,β]
and points 2β and β/2 such that both
there is
a final.ordinal.reciprocal < 2β
and
there isn't
a final.ordinal.reciprocal < β/2

However,
that contradicts the third claim, whereby
either both or neither
final.ordinal.reciprocal ⅟m < 2β
and
final.ordinal.reciprocal ⅟(4⋅m) < β/2

On the other hand,
suppose you (WM) give up
the second or third claims,
| a skipping.function isn't all.continuous
or

Which do you (WM) give up?

I will never give up the following self-evidence:
If there are ℵo unit fractions in the interval (0, eps), then there is
an x with only a finite number of unit fractions in (0, x).

Why? Because unit fractions are real points on the real line. They cannot
appear as an infinite swarm without a finite start.

The intersection of all intervals (0, eps) that can be chosen by anybody
in eternity however contains ℵo unit fractions.

But the start was at 1/1

Remember "real points" take up no spacd, so we can always pack more of
them into any finite space, so there doesn't actually need to be a "first"

If there WAS a "finite first" unit fraction, then there couldn't be an
infinite swarm of them, because then you have a finite length divided in
to segments with a finite lower bound of size, and thus have a finite
count of how many can fit.

But if there was a finite first unit fraction, then there would also be
a finite maximum Natural Number, which is a contradiction of definitions.

So, your logic is just backwards, based on embedded your misconceptions
into a made up function that can't actually exist.

Right, because infinity can never be decreased by finite operations. So
you can not expect it to.

If there was a "first", then you never had an infinite set.

For all n, s(n) != 0. Is there a point in re-wording things from how a
mathematician would write it? I ask, because most cranks are just
playing language games so re-wording things in some metaphorical way can
suggest you are disputing something in conventional mathematics.

I forgot a name for the indexing.

f[n] = 10(^n)

therefore:

f[0] = 10(-0) = 1
f[1] = 10(-1) = .1
f[2] = 10(-2) = .01
....

That is easy for me to read.

But unit fractions have internal distances and they take up space.

If there is a set of real points with distances at the real axis, then
every point can be considered as the border between two subsets. If it is
impossible to reduce the left-hand subset to a finite amount, then there
is no point available dividing infinitely many unit fractions. Then they
sit at one point. That is impossible by ∀n ∈ ℕ: 1/n - 1/(n+1) = d_n

But a space that gets vanishingly small, and thus we CAN fit an infinite
number of them in a finite space.

Nope. False conclusion. Why must the left side every become finite?

Bot by the number of points - there are always infinitely many between two
adjacent unit fractions.

If there are teally existing real points, then each one can be used, in
principle, as the border.

How about if you take the turtle's velocity and subtract it
from Achilles' velocity, then just compute Achilles' time-to-travel
to the Tortoise, and add the Tortoise's progress, to where they meet.

Though, if the Tortoise is 0 m/s, that's infinity s/m, ....

Of course it assumes that the Arrow already has a
geometric series that has a sum that equals one, ....

Adding a "postulate of continuity" to geometry was
deemed the needful about a millenia or two after Euclid.

Again this is just the Sorites/Heap, then as with regards
to the "infinitely-divided" of the "infinitely divisible",
what you want is not samples of the "infinitely divisible",
that will never end, instead the "continuum limit" of
the function that is the "infinite limit" of the divisions.

Then the values in front start with finitely many instead,
and it's just either side of that "continuous" and "discrete",
it's about the most fundamental concept relating together
the "continuous" and "discrete", in one relation.

It is, ....

Senior Hungarian officials have refused to meet four US senators who
arrived in Budapest on Sunday, Washington’s envoy to the country has said.
The American lawmakers are attempting to press Prime Minister Viktor Orban
into speeding up approval of Sweden’s accession to NATO.

Hungary is right to not meet the US war criminals.

The Mafia enforcers have arrived on tourist visas, not as an invited
political delegation. Wise to rebuff them.

For each ⅟j in an uninterrupted sequence

each final.ordinal fits leftward
not.each final.ordinal fits rightward

In other words,
infinitely.many are leftward
finitely.many are rightward
for each ⅟j

No ⅟j is in a finite start
That is the reason that
an infinite swarm is the only possibility

----
A finite ordinal is final:
It is the last which has its cardinality.

Ordinal.finality is determined by not.fitting:
If
Bob is inserted into {<j} the ordinals before final j
then
{<j}⁺ᴮᵒᵇ not.fits {<j}
{<j} ⃒⇇ {<j}⁺ᴮᵒᵇ
not.exists 1.to.1 map to {<j} from {<j}⁺ᴮᵒᵇ

Visibleᵂᴹ or darkᵂᴹ,
not.exists final‖not.final j‖j⁺¹

If
j⁺¹ is not.final and
exists 1.to.1 map g to {<j⁺¹} from {<j⁺¹}⁺ᴮᵒᵇ
then
g can be edited[1] to
1.to.1 map f to {<j} from {<j}⁺ᴮᵒᵇ
and j is also not.final.

[1]
if g(i)=j⁺¹
then define f(i)=g(j⁺¹)
else define f(i)=g(i)

That is normal,
if it is normal to be an abstraction.
I speculate that
your thinking in your yet.unstated argument
leans on the normal.ness of that.

----
A set S⁺ᴮᵒᵇ with Bob inserted which

⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯

So?

Your mind just doesn't seem to be able to understand that fact.

No, only the one ON the border would be the border, but for every one
that you might want to think of as the border, there are more that are
closer to the border.

Thus, there is NOT one (in the set) on the border, and thus there is no
"first" (from the left) unit fraction, and thus NUF(x) isn't defined.

But he doesn't, he passes the Tortoise at a easily determined finite
time (if we know the actual speeds).

This shows that to you ALL numbers have become "dark", because you can't
actually use any of them without hitting a problem.

That correctly describes an evolving infinite collection, i.e., a
potentially infinite set where more and more elements are created which
initially have not existed.
A complete, i.e. actually infinite set of ℵo real fixed points on the
real axis can be subdivided by any of its elements (since all are
existing) such that the subsets have cardinalities from 0, ℵo over n,
ℵo to ℵo, n, and ℵo, 0.

Then you are not talking about really existing invariable points. But that
is what I discuss.

But if all are there existing from the scratch as an actually infinite
set, then each one can be addressed as border between two subsets, in
principle. Even the smallest one.

It is very well defined.

Further, if
∃^ℵ y ∈ {1/n : n ∈ ℕ} ∀x ∈ (0, 1]: 0 < y < x
is false, then there must be x > 0 which make it false, i.e., which have
fewer smaller unit fractions. Therefore
∀x ∈ (0, 1]: ∃^ℵ y ∈ {1/n : n ∈ ℕ}: 0 < y < x
cannot be true for all x > 0.

Yes, the limit is well known, like the limit 0 of the unit fractions or
the limit ω of the natural numbers.

So, it wasn't on the border.

You don't seem to understand the meaning of the terms you use.

The WORDS have meaning. But the function isn't defined.

By YOUR logic, the square root of two can be shown to be rational.

Let us define Qn(x) to be the numerator of the simplest form of the
rational number that when squared equals x, and Qd(x) to be the
denominator of that same rational number that when squared equals x.

By DEFINITION, both Qn(x) and Qd(x) are natural numbers.

Thus Qn(2) / Qd(2) will be equal to the square root of 2, and has
expressed its value as the ratio of natural numbers, thus the square
root of two is rational.

You are just using broken logic.

You can't just swap the order of qualifiers like that.

But for Achilles, the limit is in the set of real values in the domain
of discourse. Not like 0 for the positive numbers, or infinity for the
finite numbers.

But there isn't a "Smallest One".

You just don't understand that fact, because you mind is just to filled
