@N3buchadnezzar Ok, thanks. It has improved since for me.

@Victor This is a serious question: why do you ask questions before even thinking a out them?

@tb - Some question is hard to figure out like square the circle...

This is no answer. This is nonsense.

Hi Henning.

Hi again.

Hi Matt & Henning

@Victor Some questions are difficult. Your questions are NOT difficult. Are you being intentionally circumloquacious??

Did someone flag skullpatrol's account for deletion?

@tb - then how do you know a graph look like a square also could look like a circle?

from robjohn's word

I guess that skull wont be patrollin around here no more =)

just trolling.

@tb Although only the parent account got deleted, the chat account didn't: chat.stackexchange.com/users/6275/skullpatrol

@Matt Won't that affect the continuity of the transcript?

@Srivatsan No idea : )

Man most of the time I read mathematical proofs, I am stumpled on how to to prove them myself. Then after reading them, they often makes sence. Although I am able to do some of the simpler ones. I just feel discouraged, because I feel that I would have never discovered this or that =(

Actually, what's the difference between a linear space and a vector space? Or: what's a linear space?

@Srivatsan Only on a set of measure zero

@TheChaz =)

@Matt I know. It's only the math account that's affected. There's still this...

@Matt two words for the same thing.

@tb Are you sure? I'm asking this question because in the definition for closed operator in my lecture notes it says "Let T be a linear operator from a normed linear space X into a normed vector space Y ..."

@Matt This confirmation is funny for some reason. =)

@Srivatsan Why?

@Matt I don't think there is a hidden twist here... But let me read your previous comment now.

@Matt Yes I'm very sure. Linear space is used in the older literature on topological vector spaces e.g. in Kelley's book about that topic.

Concerning your definition, yes, two words, same meaning.

@tb Thanks. Sorry for double checking, seems you're more reliable than the lecture notes. : )

@Matt - what word do you normally use [in case you prefer one over the other]?

@Srivatsan Vector space, I guess. I don't really know yet, I haven't made friends with the other.

I can't be here too long, so here is a call for synonym votes.

So, hi.

@Matt Yes, as tb noted, vector space seems to be more preferred these days.

And, bye!

@Matt No problem :) These things happen (using two words for the same thing) in lectures or in notes, although one should try to avoid that. It is really confusing for people unacquainted with the subject and I understand your question and double-checking fully.

But I guess "linear subspace" (or just "subspace" :=)) sounds nicer than "vector subspace". Perhaps just personal taste.

@Victor Other than this not making any sense, where did I say such a thing?

Curious: More then half the introductory probability textbooks today aren't worth the paper they're printed on and...

@robjohn Hah.

Sri: he often comments as one with an agenda

Which, as was pointed out and verified on snopes.com, is not true.

... though I can't figure out what that agenda is.

@TheChaz =)

@robjohn - i understand the whole thing now, wondering why are you go to work and come back so fast

hey anybody still awake? I wanted to bother someone with another question :o

@TheChaz I am mainly skeptical that someone would've seriously used more than 1-2 introductory books on any topic. [To all: Please correct me if I am wrong.]

@Clash on?

linear algebra, vector space, basis, your fav subject :D

@Srivatsan - Who will use the abc book too serious?

I actually asked it here math.stackexchange.com/questions/90536/… and I understood his answer, it's just I'm not sure my comments on his answer are correct and how to generalize it

@Clash sure =) . But another room.

@Srivatsan I own many high school texts in Algebra, Geometry, Algebra 2, Pre-Cal, and Calculus. And the half that is not exercises is garbage :)

I can't imagine anyone trying to learn from those texts. Or Lang's Algebra, for that matter...

I was disconnected.

@Srivatsan I'm skeptical.

Aw, cute.

@Clash Hey, one minute. I will finish up on replying.

@Matt I must say I am flattered =)

of course, no hurry, sorry for bothering you guys

gotta run. See you guys later, except those that I've ignored.

@tb Well. I will reserve my judgement on that today because I recently made a really stupid error in my answer (it's deleted now). =)

@Srivatsan Stupid mistakes happen. Btw. you had me fooled :)

Good night everyone, I'm going to bed. Have to get up too early tomorrow.

@tb Aha! =)

Reassuring, thanks! :=)

Bye, Matt!

@Victor I had to run an errand. Not work.

@Henning: Do you think you can get 4.5k of reputation before I can get 1k?

@AsafKaragila Probably not since my weekday chat-ban went into effect.

@HenningMakholm I didn't know that the chat had much to do with the reputation gain ;-)

I haven't even capped lately.

So it might have something to do after all!

Well, the chat keeps me focused on MSE rather than work. Without it, I can actually go for hours without checking the main site.

Ah.

Well, it seems that I may hit a trusted user before you would. Huzzah?

@HenningMakholm Well, I'm glad the chat is serving its nefarious purpose...

@HenningMakholm awww... I haven't capped for a long time (Nov 9, ick).

@robjohn same boat. =)

I had the caps going well for a few months, but then I got out of larval stage, I suppose. Still 12 caps from Epic, and who knows how long it will take me to collect them at this pace ...

I just capped a few days ago. It was the first time in a while, though.

@AsafKaragila Which trusted user do you plan on hitting?

@HenningMakholm Well, I plan on getting to the 20k and becoming a trusted user and then define a notion of forcing called "Bully Forcing". The conditions are composed of the statement: "Why are you hitting yourself??"

Oh, now I see. The link at the top of my pages says "tools" or "review" depending on what tab I was last viewing.

Yes.

I reported that "bug" a while ago on meta. Jeff replied that this is how it would work from that point.

@AsafKaragila Heh. I had thought I had somehow lost the "tools" link and was pointed to the "review" link.

Yeah, I had that same thought.

@AsafKaragila Asaf: the edit you just approved overrode an addition by the OP

I hate deadlocks.

Wait what? I don't see it in the revisions!

@AsafKaragila Recjoice, then: editing on MSE never deadlocks, because it doesn't even synchronize!

@AsafKaragila It's just the sentence "I'm doing a group review with a few classmates, help is much appreciated." added before the how do I find r?

@tb Oh, that's mostly irrelevant to a question on MSE, is it now?

@HenningMakholm We're not here to give badges of shame, are we? :-)

@AsafKaragila I haven't seen it. I just saw that Paul's suggestion was posted an instant before the OP made a change to the question.

Oh.

What the ...

@tb May I ask that you put it for deletion when it's closed?

@Srivatsan: did you have a comment? I got a ping.

Indeed. Perhaps editing to remove the contact details right now would be in order.

@robjohn Something about the tools. I figured it out. =)

how does one show that $\frac{16}{64} = \frac{1}{4}$ ?

@AsafKaragila Executioner needed.

@AsafKaragila Get paid for helping someone cheat.

Yes, I know.

Interesting: never seen that:

@tb Can you declare time of death, and kick that question away from the site?

@AsafKaragila done. But still need two more votes.

Also, two guys offer a 500 points bounty and transfer the points to me. This way I could also vote for deletion before the day ends.

@AsafKaragila trusted user must simply be a title ;-p

@AsafKaragila Hey, don't get all worked up! :) That bounty move wouldn't work, because the bounty can only be awarded 24h after it was set up.

I know I know :-)

Hmmm. Four more upvotes and I hit the cap limit.

30 minutes to go.

Anyone got a simply AC question - now is the time for it ;-)

;)

No.

@AsafKaragila Would you be up for something about the relation between independence proofs for ZFC versus for NBG?

Now Playing: Jimi Hendrix - The Wind Cries Mary

@HenningMakholm No, since I am unfamiliar with actual work with NBG other than showing that the axiom set is finite (unlike ZFC)

OK. Couldn't be done in half an hour anyway, I fear.

True.

What do you have in mind, though?

Not sure how I would formulate it as a concrete question.

Still, what's on your mind?

Just figured out that I have to reread 1½ chapters of Kunen because I arrogantly figured that because I know NBG I could skip all of the nitty-gritty part about proper classes actually being abbreviations blah blah blah.

You are raising a good issue, too.

Then it suddenly dawned upon me that if I were to do a parallel development for NBG I would have to speak of collections of proper classes anyway in order to have, say, V as an inner model, so all of the nitty-gritty would be relevant anyway.

@AsafKaragila this sheds new light on the first sentence here...

Since NBG is a conservative extension of ZFC, every proof in NBG which only uses sets can be written as a proof in ZFC. However if we consider class forcing in NBG the treatment is much easier than it is in ZFC; but when can a notion of forcing be adapted to such proof?

@tb Quite.

Well. In the remaining 20 minutes I guess you're all just gonna have to upvote my older questions, since no one asked an AC related question :-P

Ah, it is close to the end of an MSE day. I am half way to capping, perhaps because I spent way too long on a logarithm question.

I'll have to chase down the proof that NBG extends ZF conservatively one of these days. Kunen makes a good point (as far as he makes it) that the ZF axioms are better intuitively motivated than the sweeping class existence axioms of NBG.

I do agree. However recall that we were brought up with sets, not with classes.

I tend to take Shelah's approach on that matter - good axioms are those that you don't even feel when you use them.

@robjohn Oh, I see that your answer fit the bill better than Sivaram's, even for the OP :)

Or, if you want to process things through my twisted mind:

Good axioms are like good condoms, they keep you safe from contradictions but you don't really feel them when you use them to do your business.

@tb Yes, I feel a bit bad about stealing the acceptance, but it passes ;-)

contradictions?

Yeah. You don't want axioms that derive $x\in\varnothing$, or something like that.

I know what contradictions means in terms of axioms, I just do not see how contradictions could be related to the similie you were trying to make =)

Similie?

Isn't "we used a condom, yet she got pregnant" a contradiction?

which will lead to contractions 9 months later.

Perhaps also a contract between two parts

When the girl doesn't give birth? The black little facehugger instead bursts forth and springs out of her belly onto the face of the doctor...

Reminds me of a manga i read...

Uzumaki, Ever read that one ?

No.

Horror manga, it has given nightmares to most of my friends.

Guys turning into snails, and then starts mating. Etc

Have you watched Takashi Miike movies?

Audition, Ichi the Killer, Gozu, Visitor Q...

mangareader.net/1358-44794-1/uzumaki/chapter-11.html

I`ve red Ichi the Killer, quite the good read.

The movies are awesome.

Fascinating story, and interesting characters. Although some of them had rather flart personalities.

To this day Audition remains the movie I've most "WTF?!?!" about.

I once spent an entire ngiht with a girl watching horror movies, it was awesome.

Uzumaki, is perhaps the manga which has scared me the most.

Also som guro, but that is just gross. Not actually scary

They put an immortal baby inside of a blender, I laughed so hard when I read that.
