I always think of Godel’s Completeness/Incompleteness theorems when people invent new encoding systems, etc.
XML : How do I encode “<“?
<
Well how do I encode ampersand?
&
etc.
CSV How do you encode a comma?
Enclose it in quotes.
How do you encode a quote?
Double it!
My practical interpretation:
Define a system: There will always be something outside of its boundaries!
My favorite example is good old
int getc();
It returns a char or -1 for EOF/End of File. EOF is outside of the char system.

A rule having no exception: "death and taxes"
The difficult we do right away...
...the impossible takes slightly longer.

I once discussed that with my religious brother-in-law. He insisted that there are exceptions to that rule. May not to the "taxes" part, though.

Agreeing that a proof is valid is not the same as stating that it must be true. Now claiming that it is true could suggest that one should provide the example. Or provide other discussions that would suggest it is true. Or just believe and dispense with the work.
My favorite example with this is geometry (Euclidean) where parallel lines do not intersect. I certainly believe it. And I doubt anyone can provide an example that shows they do intersect. But for that matter they cannot provide an example where they do not intersect either.

Though I am not a theoretical physicist, have heard that "space is curved", whatever it means. If space is curved, will there be a possibility of parallel lines meeting? Not sure.

Spherical geometry rather than Euclidian.
But one can also start in on a definition since a line, even theoretical, could still be claimed to be something that must exist in the universe. So if the universe is curved then the line must be as well.
But then what happens with the degrees in a right triangle which can only exist if those lines do not intersect.

You :
does a solution to the Russel Paradox exist
ChatGPT
Yes, several solutions to the Russell Paradox exist, which emerged after Bertrand Russell presented the paradox in 1901. One common solution is to restrict the comprehension principle, which states that for any property, there exists a set of all objects that have that property. By restricting this principle, mathematicians and logicians have been able to formulate set theories, like Zermelo-Fraenkel set theory (ZF) or von Neumann-Bernays-Gödel set theory (NBG), which avoid the paradox by disallowing the formation of certain "self-referential" sets. Another approach is to distinguish between sets and classes, where classes can contain sets but not be sets themselves, thereby sidestepping the contradiction. These solutions have allowed set theory to develop into a foundational framework for mathematics without succumbing to paradoxes like Russell's.
Me : If Statement 2 is a rule it must have an exception.
Conclusions: Statement 1 has no exception. There is at least one rule which has no exception.

Thunderbird has been my SMTP client for years. My problem may be Thunderbird related, but my gut feeling says that it is not ...
I have several times noticed, when fetching new mail, that the status line says: 'Retrieving message 4 of 12', or something like that. When it completes, there are far less than 12 new messages in my inbox.
Tonight, it retrieved 'x of 6 messages', but only a single new message was in my inbox. There is nothing in the Thrash (and when something goes to Thrash, a counter displays the number of new entries). If a filter had redirected the messages to some other folder, it would have been seen in new count for that folder. Anyway, I have looked through every single folder, without finding anything new.
This is a fairly new thing; I have noticed it for a few weeks. Can anyone explain what is happening? Why does Thunderbird report 6 messages and display only 1 to me? I am suspecting that someone are trying to check if my mail address is valid, possibly also to see if I am reading the mailbox, by sending messages which somehow is marked to be deleted immediately, or possibly at a specific point in time that is already past - but I wasn't aware that SMTP had such a feature.
For the sender to be notified that I have received the mail, I am aware of an SMPT option for that. Thunderbird has several times presented a dialog box telling that the sender has requested a confirmation that the message has been received, with buttons for 'Return confirmation' and 'Do not send confirmation'. I have seen nothing of this when messages are 'missing'. I wasn't aware of an SMPT option for 'silently' generating a read confirmation - does it exist? If it exists, can it be used to secretly 'ping' me, the way it appears to me now?
Is there some other possible explanation? Could it be a Thunderbird hiccup? (That is a strange hiccup!)

Duplicates in 'All Mail' and Important ? I've seen that happen, but didn't pay attention to the message count.
