Of course. Further this is not a lie. It is correct.

Only all definable endsegments have an infinite intersection.
|∩{E(k) : k ∈ ℕ_def = ℵ₀ .
∀k ∈ ℕ_def: ∩{E(1), E(2), ..., E(k)} = E(k) /\ |E(k)| = ℵ₀ . (*)
You cannot find an exception.
∩{E(k) : k ∈ ℕ} = { } .

Every endsegment that you can define belongs to a finite initial segment. If you cut the sequence at any point you can
E(1), E(2), E(3), ..., E(k)|, E(k+1), E(K+2), ...
then you will get
|∩{E(1), E(2), ..., E(k)}|= ℵ₀
and
|∩{E(k+1), E(K+2), ...}| = 0

University of Applied Science. Augsburg will become a Technische Hochschule.. This term should be well-known also in US (ETH Zürich, RWTH Aachen, also Dedekind was in Brauschweig at a TH).

No, but in some point he could correct the mistakes of set theory.

Nonsense. The points are there, fixed on the real axis. In order to prove that the set has no difference to zero you can only use its points. But they fail. That means IF there is no distance to zero, THEN there are dark points which cannot be individually checked in the set.

IF the set has no distance from zero, THEN not all its points can have an infinite distance from zero. Is that really too hard to understand?

The privately lead journals have a censorship by matheologians who are too stupid or too dishonest to accept what I just wrote you.

Is that a known term in the US? I've never heard of it before. Would
someone know, for example, that such an institution does not award
doctorates?

Quite a retraction from this absurd claim: "My students would be better
examiniers than all you may have in England".

>> I wonder if you will answer any of these?

I asked nine questions. You commented on four but only two were actual
answers. Basically you are avoiding saying what I must assume is the
case: that not one checks the technical content of courses at your
institution and that you could teach pretty much anything you like with
no come back.

I also asked if the other higher education institutions -- the ones that
have a full range of degree programs and award PhDs -- are any different
but maybe you just don't know how they work.

There has to be a contradiction, not a remark in some corner of the
Internet.

I look forward to congratulating you on the appearance of this important

Not hard, impossible, because you don't say what you mean, probably
deliberately. What does no distance between a set and a number mean?
You should probably give two answers because, presumably, in WMaths that
first "IF" should come out differently.

The term "distance" is playing a magical role here. Not only can it
apply to sets, none of the elements in the set have an infinite distance
from zero in any conventional sense of the term. The largest
conventional distance is 1.

(For reference, the set is { 1/n } for n in ℕ⁺.)

I am not sure what WM is trying to say as well. Perhaps something like
the absolute distance between n and n +- 1 is one?

-2, -1, 0, 1, 2, ...

abs(-1 - -2) = 1
abs(0 - -1) = 1
abs(1 - 0) = 1
abs(1 - 2) = 1

abs(-2 - -1) = 1
abs(-1 - 0) = 1
abs(0 - 1) = 1
abs(2 - 1) = 1
....

Therefore:

abs(2 - -2) = 4
abs(-2 - 2) = 4

?

There are several alternative terms that overlap in the anglosphere:
vocational college, polytechnic, technical college, institute of higher
education. The common trait for all of thsese is that they're avoiding
the word "university", which is what makes UAS stick out as an outlier.

Nope. It doesn't. Whatever came before the Greeks was unremarkable rubbish.

Some years ago I wrote a letter to the Minister of Education in Bavaria,
the department responsible for schools like the Hochschule Augsburg and
for all the schools including the universities.

I asked how they can justify the situation with Mückenheim, whose
incompetence is self-evident.

I also asked what mechanisms the department has to insure the quality
of education. And I asked whether they had any responsibility for the
health of their employees, in cases where the latter cannot deal with their
own health issues, referring to Mückenheims obvious psychological problems.

This letter was forwarded to the President of the Hochschule Augsburg,
Professor Dr. (Dr. Dr. honoris causa mult.) Schurk, and Mückenheim was
made aware that there was (yet another) such complaint.

The reply was in essence this: Freedom to teach, whatever the teacher
chooses to teach, is a 'higher good' and the administrators do not have
the authority to interfere with a professors choices. The rest of the reply
was waffle. The point here is that these technical colleges were doing everything
they could in order look like real universities. The teachers are 'professors' and
the institution was renamed from 'Fachhochschule' to 'Hochschule' and recently
to 'Technische Hochschule'. At the same time the level of instruction is sinking
because the real universities have become much more accessible than used to be.

In essence the problem is this:
-- Once Mücke was hired as a civil servant he could not be fired; they are stuck with him
-- It is understandable how such an error can be made: The
man apparently has a PhD (in physics) from a real university (although Göttingen has never
recovered from the ethnic cleansing perpetrated by the Nazis, it is
still one of many competent provincial schools). The man worked in industry for
several years, which was (maybe still is) actually a prerequisite for teaching positions
at schools of this kind. The rationale for this requirement is sound: The students learn
practical engineering in a 3-year course; they do not learn math and physics and chemistry.
It is very surprising that somebody with this background cannot teach mathematics on
and below the level of first-semester Calculus.
-- If the department were to relieve Mückenheim of his duties they would have to actually
open a case for an additional slot for an additional 'professor', which is a significant
bureaucratic undertaking and entails admitting the error; and it means re-assigning Mückenheim
to some kind of paper-shuffling task that he can actually manage.

Incidentally the respondent, Prof. Dr. Dr. Dr. Schurk had a website propagating all
sorts of health quackery. His multiple Dr. honoris causa titles came from 'universities'
in the Ukraine and the Russian provinces, with whom the Hochschule Augsburg organized
'cooperative projects'. In other words, funds for academic cooperation were funneled
into a black whole and, in gratitude, titles were awarded. That's my guess.

It means that no unit fraction lies between the set and zero.
The set spans the interval (0, 1] even if all other points are removed.
There is noting betwee (0, 1] and 0.

> The term "distance" is playing a magical role here.

No, it is simply an abbreviation.
Definition: The distance of an object is X means there are X unit fractions between the object and zero.

Every unit fraction has distance ℵo. The set has distance 0. But this can only be checked by considering its elements because here the set is its elements. For every considered unit fractions is fails. Hence not all unit fractions can be considered.

Here is the letter - I wasn't able to find the reply. I probably trashed it at some point.
Google translate does a surprisingly good job - I have left it untouched, despite some
clumsiness.

Mr. Johann Zwirglmaier 27.9.2011
Bavarian Ministry of State
Science, research and art, Section C12
Salvatorstrasse 2
80333 Munich

Dear Mr. Zwirglmaier,
A Mr. Wolfgang Mückenheim is employed as a professor at the faculty for general sciences at the FH Augsburg. He is a math and physics teacher and apparently unable to carry out his duties.
Mr. Mückenheim deals with an esoteric form of mathematics, which he himself calls "MathRealism", dealing with objectively nonsensical and misunderstood elementary mathematical questions, especially from set theory. According to Google statistics, he has written 24,729 (in words: almost twenty-five thousand) posts in various Internet discussion forums over the past 7 years, all of them essentially on one and the same topic. In addition, one can find several formal essays by Mr. Mückenheim on the Internet, which prove his complete incompetence as a mathematician.
At the University of Applied Sciences in Augsburg, Mr. Mückenheim gives a lecture on “The History of the Infinite”. Here his nonsensical theses are presented and in exams it is required that the students repeat his false conclusions.
In this context, I would like you to answer the following questions:
1. How does your ministry monitor the quality of teaching at Bavarian universities?
2. When were Mr. Mückenheim's courses last assessed? Is there a written report on this?
3. What is the correct course of action for the responsible citizen when faced with obviously incompetent officials?
4. Mr. Mückenheim's behavior raises the suspicion that he suffers from a serious mental disorder. Isn't the employer obliged to take care of medical measures?
Kind regards,

Re: Question on Hilbert's Hotel.

It's not easy to get the correct cultural translation. But, almost
everywhere, institutions now want to have "university" in the name. I
can't blame them, but it seems a shame. Here in the UK, in many cases,
they turned their backs on over a century of excellence associated with
the old name.

In the US, a few institutions have transcended this issue. I doubt
anyone at Caltech or MIT care about the fact that the word university is
not in the name, but the PR benefit will more important if you don't
already have a stellar reputation.

sounds right, WM does not know math at all. His students do not need to either.

this is key;
"The students learn practical engineering in a 3-year course; they do not learn math and physics and chemistry."

so it is not engineering school at all, but a technical school that generates technicians.

also on their website, they imply the courses are free, and may be aimed at new immegrents to Germany,

https://www.hs-augsburg.de/Binaries/Binary48053/Infoblatt-Wintersemester-2022-engl.pdf

I had an employee from Germany, a technician, who in Germany worked for the telephone companies, and filed relay contacts for years, with no upward
mobility in the German society(union job), so he immigrated to USA. He did quite well here.

No, it can't be that.

As usual it's a word game, the aim of which is to find words that make
infinite sets seem odd. Every 1/n has a vast infinity of fractions
between it and zero so each and every one is "very far from zero". Yet
there is "no distance" between the set {1/n} and 0 because, taken
together, "all" leave no gap with zero.

Given U = {1/n for n ∈ ℕ⁺}, had he just said that

∀n ∈ ℕ⁺: |{ f ∈ U with f < 1/n}| = ℵ₀

(there are infinitely many unit fraction less than any particular one)
and

~En ∈ ℕ⁺: ∀f ∈ U: f > 1/n

(there is no unit fraction less than all others) he would simply have
two facts that apply to his supposed WMaths as much as to what he calls
"set theory". Even those words won't do because

there are infinitely of unit fraction less than any particular one

and

there is no unit fraction less than all others

are not at all strange or adds with our expectation. For WM, words like
all and every are not aids to understanding by opportunities to obscure
and switch quantifiers.

Interesting.

To be honest, I would hope that all ministers, in all countries and
states, would take a hands-off stance when faced with questions like
this, but this reply goes much further. Freedom to teach anything is
clearly not a "higher good", but I approve of the part about having no
authority to intervene.

In the UK, there was a body, independent of government, whose role was
to ensure that all universities have robust mechanism in place to ensure
the quality of their educational offerings. It would be naive to think
that this worked without problems. It's was a very bureaucratic
organisation and an audit consisted mostly of a lot of paperwork
intended to show that you had the right processes in place.

But one of these processes was the external examiner system. It was,
and I hope still is, invaluable. I was course director for one of our
degree programs and the help I got from various external examiners over
the years was immense. This is why people (like me) also volunteered to
do the job for other institutions as there was no pay. OK, we took the
external examiner to a couple of posh lunches and dinners (if they had
to stay over), but that's about it.

At a large department, the whole thing took two days. They reviewed
syllabuses, and coursework and examination papers both as set and the
work returned by students. They read a sample of all dissertations and
ever dissertation where the students was at a "class boundary"
(i.e. close to getting a 1st, upper or lower 2nd, or close to failing).
They could not change marks, but they could, and often did, comment on
things like courses with very high or very low pass rates. The
examination board (the official body on which they also sat) might then
make some adjustments. They also kept the course directors, like me, in
touch with what other comparable institutions were doing.

There is obviously nothing comparable at Hochschule Augsburg. If there
were, the external examiner's report would be worth a read!

Once a lecturer ("professor" is a specific title in the UK) has tenure,
you can't get rid if them here either except for what used to be called
"gross moral terpitude"! But in some places (where I worked was one)
you did not get tenure right away but only after a few years. But
unlike in the US, it was not a "promotion" to get tenure, it was only
denied if you had failed to perform your duties satisfactorily.

A lot of this has changed, so I don't really know the details any more,
but I think the basics remain in place.

Ah. That explains a lot. In the UK, it would be people like this who
would have to take responsibility for weeding out bad courses, but if
you are champion of alternative facts, who's to say what the
intersection of all end segments of N is!

Bad at probability and statistics too, I see. Also, very bad logic given that I am an exception, not the rule. I would still be able to beat the crap out of you in a physical fight and I am old enough to be your grandpa. LMAO..

They estimated that I had 3-6 years left to live back in 2013. Do the arithmetic moron! I am still here so get used to it.

You will be annihilated - if not by me, then by my fine young warrior acolytes who are many times more intelligent than you could ever hope to be, fake mathematician that you are.
