No, I don't mean that. And I've already explained the difference. And
again, since you are unfamiliar with even the most basic notions such
as a primitive symbol, I'm pretty much wasting my time every time I
write up explanations for you to receive in the lap of your own
ignorance.

No, they are very much NOT that.

It just doesn't even work in the way you pose the question. I just
can't explain how to do certain tasks on a computer to someone who
won't even push the "on" button on the machine. I just can't explain
how to regard mathematical defintions using mathematical logic to
someone who just won't even read page one of a textbook.

No, my point is that I can't explain page 100 to you if you won't read
page 1.

Nor can I keep very interested in a conversation with someone such as
you asks me questions on the subject but then replies to my answers
with essentially, "Who asked you? Who cares?"

Cardinals are ordinals and in a set theory: sets.

Generally it's known that you get cardinals from the previous using the
powerset operation, and ordinals from the previous using the successor
operation.

So, consider the formation of the ordinals where the powerset of the
previous ordinal is the successor.

The powerset is order type is successor with ubiquitous ordinals, and
naturals.

You might say "the von Neumann ordinals are simpler than that" and also
they contain less information.

For example in comparing ordinals as integers sets are defined by their
elements.

Infinite sets are equivalent. That says there exists bijective
mappings between any two infinite sets, with composition. If you're
familiar with Cantor's results you've seen and probably accepted
proofs, or as I call them results, about functions between the naturals
and reals or naturals and powerset of reals.

Basically that's about three things: the antidiagonal argument and
nested intervals about well-ordering the reals and mapping them to the
naturals, and the powerset result and coded binary powerset result
about inversion, and the set of natural numbers being itself.

The reals are ordering sensitive in that the way you order them in
mapping to other naturally ordered sets affects the ability of them to
be described. The real numbers are consistently not a set in ZF, not
thus a set theory.

There's only one theory with no axioms.

This ball and vase problem, marbles in a jar, you have a discrete
process occurring at each t = 1/ 2^n for integer n > 0, or n >= 0,
whatever. Then, there's some n = oo which is when the process
completes, because, for no other value of n would this "completion"
occur. So, the numbers go right to N, infinity, or, it's ridiculous to
suggest the rate out overcomes the greater rate in.

That might violate the problem.

There are a few correct statements in there, but most of the above is
just plainly incorrectl mixed with gibberish.

I'm just cursious to know what satisfcation you derive from typing up
and posting such nonsense, post after post after post, year after year
after year.

Through what powerset operation do you get the cardinal 3?

Through what successor operation do you get the ordinal omega?

In that way you do not construct the ordinals, but the Finlayson numbers.
They go like 0, 1, 2, 4, 8, 16, 32, ...

Well, at least they contain ordinal numbers like 3, 5, 6, 7 etc.

I understand it.

Please identify something you see as incorrect or don't understand.

There's no universe in ZF. So, quantify over sets.

Basically, I plan to cut and paste the posts into other documents, in
the evolving discussion.
