    Can you explain how NUF(x) can increase from 0 to many more in one point x although all unit fractions are separated by finite distances of
    uncountably many x each?

    Nonsense. Jumping by X at a point x requires X unit fractions at that

    Viell. Hast Du ja nur Probleme mit dem Begriff "Sprungstelle"?

    Hier wird ein schönes Beispiel geliefert:

    "Ein einfaches Beispiel für eine Sprungstelle unendliche Höhe
    liefert die Funktion

    f(x) := 1/x, x e IR\{0}
    f(x) := 0, x = 0

    bei x0 = 0."

    Quelle: https://www.spektrum.de/lexikon/mathematik/unstetigkeit/10568

    In our case we have (mutatis mutandis):

    NUF(x) := aleph_0, x e IR+
    NUF(x) := 0, x = 0.

    MEANING:

            NUF(x) = 0 for all x e IR, x <= 0

    Are you unable to understand simple sentences?

    No. Only for every x > 0 that is in a distance of at least ℵo finite intervals from 0.

    The same as the sign function.
    No, ℵo finite intervals do not fit between [0, 1] and (0, 1]. The sign

    Where do you get this requirement from?

    ℵo unit fractions occupy ℵo finite intervals.

    Consider the sign function times infinity.

    The sign function can change from point 0 to all points of the interval
    (0, oo) without exception. NUF needs some of these points to acquire ℵo
    unit fractions.

    Perhaps, with professional counseling,

    you could explain how NUF(x) can increase from 0 to many more in one
    point although all unit fractions are separated by finite distances?

    Sure, it jumps because of your stepwise function.

    Real line going to the right:

    (0)->(1/1)

    There is no so-called smallest unit fraction that magically sits next to zero! Damn it WM!

    Don't claim. Explain how NUF increases.

    We can say as the unit fractions get smaller and
    smaller forevermore, that their limit is zero.

    Irrelevant.

    However, NO unit
    fraction, no matter how small, ever equals zero. Period.

    Of course not. Therefore NUF cannot change at zero.

    Because is isn't a properly defined function.

    It has no finite value for any finite value of x > 0.

    Thus, one need no figure how it gets from 0 to any other number, since

    If there are no unit fractions then the number of unit fractions is

    | A jump _can_ be by

    | <different conceivably.understood proof>


    |ℝ| is the maximum size of a jump.

    ∀ᴿx≤0: NPR(x) = |(0,x)| = |{}| = 0
    ∀ᴿx>0: NPR(x) = |(0,x)| = |ℝ|

    f(y) = y/√​̅y​̅²​̅+​̅1
    f: ℝ → (-1,1): 1.to.1

    g(y) = (y+1)/2
    g: (-1,1) → (0,1): 1.to.1

    g∘f(y) = (y/√​̅y​̅²​̅+​̅1+1)/2
    g∘f: ℝ → (0,1): 1.to.1

    x⋅g∘f(y) = x⋅(y/√​̅y​̅²​̅+​̅1+1)/2
    x⋅g∘f: ℝ → (0,x): 1.to.1

    |ℝ| ≤ |(0,x)|

    Also
    ℝ ⊇ |(0,x)|
    |ℝ| ≥ |(0,x)|
    |ℝ| = |(0,x)|

    ∀ᴿx>0: NPR(x) = |(0,x)| = |ℝ|

    Jumps "at" a point are between
    nearby points.
    WM admitted that much in a recent post,
    but changed what "change" means to him.

    |IN| is "the maximum size of a jump",
    namely "the size" of the jump "at" 0.
    (Hint: NUF has only one jump, namely "at" 0.)

    I continue to accept the proofs that
    ∀ᴿx>0: NUF(x) = |⅟ℕ∩(0,x)| = |⅟ℕ|

    The unit.fractions between 0 and different points x
    are not the same unit.fractions.

    Not claimed that they are the same.

    For different points x₁ x₂
    the unit.fractions ⅟ℕ∩(0,x₁] and ⅟ℕ∩(0,x₂] are

    |⅟ℕ∩(0,x₁]| = |⅟ℕ∩(0,x₂]| = |ℕ| = ℵ₀

    for all points x > 0
    there are ℵo smaller unit fractions,
    then
    for the interval (0, oo)
    there are ℵo smaller unit fractions.

    No.

    unit.fractions in (0,x] which,
    because

    are ℵ₀.many.

    No unit fractions are smaller than (0,∞)

    Or is there a point in (0, oo) which
    is not an x > 0?

    No, but
    there is no point x in (0,∞) such that
    ⅟⌈⅟x⌉ isn't = max.(⅟ℕ∩(0,x])
    and
    unit.fractions in ⅟ℕ∩(0,x] aren't

    But no value of x can BE that left hand side of (0, oo) because if such
    an x did exist then x/2 would be outside the interval, but also positive.

    The fact being that these systems are UNBOUNDED, and thus there does not
    exist a number "next to" another number, but we just have an infinite
    density of numbers.

    This function has to increase by at most 1. Between [0, 1] and (0, 1] it
    cannot increase at all.

    That means NUF(x) is constant over the whole interval (0, oo), i.e., a
    false expression because it follows that NUF increases from 0 to
    infinity between [0, 1] and (0, 1].

    The ONLY rule in WMaths is: "If Crank Wolfgang Mückenheim from
    Hochschule Augburg doesn't like it it is false, if he likes it
    is true."

    This is not a big issue on Usenet, he's not alone with this way
    of "thinking".

    It is, though, a BIG scandal in Hochschule Augsburg because he is
    TEACHING there, and the institution is hiding itself behind
    "academic freedom".

    Of course he has forgotten to state the "domain" of his "theorem"
    explicitely. But it's reasonable zu assume that "X" and "x" here are
    used as as varibles for real numbers.

    Find a counter example or accept it.


    But no [...] x can BE that left hand side of (0, oo) because if such
    an x did exist then x/2 would be outside the interval, but also positive.

    0 can't be "left hand side of (0, oo)" (WM)?

    Hint: WM uses non-standard terminology here. "X is left hand side of (0,
    oo)" means: Ax e (0, oo): X < x. We might abbreviate this with X < (0, oo).

    If we state his "X is left-hand side of every x > 0" in the usual formal/symbolic language (which is uses in the context of set theory) we
    get: "Ax e IR, x > 0: X < x".

    Now clearly: Ax(x e IR & x > 0 <-> x e (0, oo)). Hence his "theorem" is
    just a simple tautology (based on a simple definition):

    Def.: X < (0, oo) :<-> Ax e (0, oo): X < x

    Now:

    Ax e IR, x > 0: X < x <-> Ax e (0, oo): X < x

    since by definition (of an intervall) Ax(x e IR & x > 0 <-> x e (0, oo).

    Hence (with def. from above):

    Ax e IR, x > 0: X < x <-> X < (0, oo) .

    A trivial "result".

    Though I'd prefere it to state it the following way:

    AX e IR: (Ax e IR, x > 0: X < x <-> X < (0, oo)) .

    _________________________________________

    Now we may, say, consider the set {X e IR : X < (0, oo)}. Then we get:

    {X e IR : X < (0, oo)} = (-oo, 0].

    Using an additional "extension" of "<" we might even state this result as

    (-oo, 0] < (0, oo)

    Meaning: Ax,y e IR: x e (-oo, 0] & y e (0, oo) -> x < y.

    Of course there is no unit fraction left-hand side of every x.

    There is no smallest unit fraction. No unit fraction represents zero. Therefore there will always be a gap between any unit fraction and zero. Period. Done. You are a special type of thing... The "dark" thing... Too stupid for measure.

    I guess with "left-hand side of" he means "which is smaller than".

    Of course there is no unit fraction which is smaller than every x [e
    IR, x > 0].

    Aha!

    But for every x e IR, x > 0 there is a unit fraction which is smaller
