@Lord_Farin Only L remains.

@DevashishKaushik Gone.

@DevashishKaushik Left this and this.

NCQs up for deletion: 1, 2, 3.

PSQ with copied hint is up for deletion.

This should probably be reopened.

@XanderHenderson Why are logic and computability conspicuously missing from the list? =|

@user21820 gone

@user21820 First "this" is open now for deletion.

@user21820 Pish tosh. Who needs that BS? We're mathematicians, not dirty... shudder philosophers. :P

@XanderHenderson You can't prove that! =P

Even if it's true! (But it's not, of course.)

@user21820 Of course I can't. I don't know any logic. Again, mathematician, not philosopher. Derp.

:P

That being said, I think that this issue really is that most mathematicians don't really know logic and/or computability theory with any specificity.

It is hard to require a class that so few mathematicians are actually qualified to teach. :\

@XanderHenderson Yea that was why I was sad. And, amusingly, there is a user now in this room with an avatar to express my face.

History of mathematics is another area where I think that we are sadly lacking in competent instructors.

@user21820 Heh.

@user21820 gone

@user21820 You mean "undeleted"?

close delete Suspiciously simple and at 04:41.

@XanderHenderson Maybe we should continue this in SBA's realm, but I can't resist linking Smullyan's excellent writing on Logicians who reason about themselves.

@XanderHenderson Well I voted to delete first, since it was a bit lacking, but then I thought that maybe not since it's much better (relatively speaking) than the linked 'duplicate'.

@user21820 The linked duplicate has now been deleted (I cast the deciding vote).

I'm not sure that I feel that the newer question should be reopened, however.

Though I do agree that the newer question is better.

Sure, thanks!

@XanderHenderson Hahaha! :D

Their previous question is from 2016, for crying out loud! How do they not know what a Cartesian product is!? I don't mean to make fun but . . . How!?

I flagged it (twice) and voted to close.

PSQ.

@XanderHenderson: Thanks for your vote on that "linked duplicate".

close delete PSQ.

thanks @quid

What should I flag for a question like this one ? I'm really not sure

I'm asking for if it was to happen in the future

@Jakobian You could have flagged it as rude or abusive.

delete Utter nonsequitur

Consider for deletion: 1 and 2

Not a big fan of this most recent meta question.

@RRL Both are now deleted.

@amWhy: Thank you.

Hi can you find what happened to my answer there ? The OP could delete his question and my answer ? Don't you think there is a problem there, the same user being asking more similar questions the next day.

@RRL Thank you for posting links to those questions!

@reuns Do you have a link or two to the "similar questions" that the user has posted after that question that you answered?

I think I found the post, @reuns, and have commented on that subsequent post, addressing the asker, and have flagged the question with a link to the deleted version which demonstrates that the second post was the same question originally asked and answer, then deleted by the asker.

@reuns that's possible as long as your answer does not have an upvote. This happens with some frequency. If it happens just raise a flag and we undelete.
