...is a list question too broad when I believe the set of answers might in fact be empty? That's not too broad, right?

@ACuriousMind If that's the case, what suggests to you that it's too broad?

@HDE226868 A pending close vote as too broad, duh :P

@ACuriousMind (Groan) Besides that.

Are you asking me why I'm even wondering whether this question is too broad, or are you asking me what I in general consider too broad?

@ACuriousMind I suppose this specific case. In other words, looking at the question, what makes you think that this case is too broad? There are two main possible general reasons: 1) Too many answers, and 2) Any good answer would be too long. I know #1 seems to be false here, so what makes you think that it would fall under #2?

@HDE226868 No, I don't think this question is too broad, hence I voted to leave open. But I'm wondering whether the person voting to close seriously thought there would be many possible answers, or whether they just thought "oh, this could become a list, it's too broad" and voted to close without actually stopping to think how many answers there could be.

@ACuriousMind Ah, that makes more sense. I think I know which question you're talking about (and think that that one should perhaps stay open), but in general, I would vote to leave open.

hey hey

It's snowing :3

I wonder what Lovelock's theorem looks like in 2D

@Slereah What do you mean, "how it looks like"?

E.g. here's a proof of a Lovelock-like theorem for arbitrary dimensions.

neat

ew jet bundles

:D

"$C^2_1$ denotes contraction of the first covariant and second contravariant indices"

See that's what happens when you go index free

Yeah, contraction is one of the few evils that incurs

I also, for reasons not entirely clear to me, hate the interior product.

Hm

Apparently the Lovelock theorem basically says that only the cosmological term remains in 2D

Which makes sense I suppose

Noooo

Why is it all German

Hehehehehe

"Einstein was a raving lunatic, and so are his disciples."

The anti Duffield

^ See, even butter won't melt in his mouth. It is weird that this innocent seeming guy is setting up so many sockpuppets to "destroy the site" :P

such evil

Never trust a particle, they make up everything.

Haha...no one?

Oh hey, a person

Sup?

@user36790 I'm assuming that's a joke but you make me a little nervous. Well done, I think. :-P

@TheDarkSide I don't get it.

May I speak with a mod privately for a moment?

aren't you a mod

aren't you everyone

@Slereah While this is all funny, I would like to ask you all to stop posting links to this person's posts about me. I don't mind the jokes (actually I find this all hilarious), but I'd appreciate not feeding the troll, since this involves me personally.

I never linked to those posts

(I don't mean that you were personally posting links, I mean the general "you")

"you all" != "you"

@DanielSank sure, let me pull you into a private chat room

@DanielSank incidentally I also think this is a good idea. I'm not comfortable using mod powers to censor links to the posts from the chat room, but I do think there's no good reason to link to them, and it would exhibit good judgment not to do so.

@DavidZ Well, that's what I was going to request in private.

oh okay then :-)

@ACuriousMind Yes, we should try to fix that.

@user36790 Again, I don't mind the joking around but I think we should probably not encourage discourse with the troll.

I think the whole thing is kind of funny, but I'd rather not encourage it.

...and as my sock puppet you must do as you're told.

haha

I recommend dealing with troll posts by flagging as offensive and pinging the mods here to remind us to check the flag queue. No need to post links in chat.

@user36790 I prefer to be a lower profile ruler.

Xerxes was effective, but he lacked panache.

"In an unpublished work Klinkhammer and Thorne"

whyyyy

Why would you mention an unpublished work

what frankenstein manifold is this

@DanielSank :: Kneels :: Sure, my Lord! :P

But considering the diligence that the troll has gone about posting all that, I think this case is either:

(i) you pissed someone off really bad,

or,

(ii) it is case of someone trying to use a virtual profile (or rather, profiles) to settle some real life scores.

It looks more like (ii) to me, for I don't remember you being rude on this site.

@Slereah lol

@ACuriousMind Sup?

I stand by my opinion that it's mainly a math question.

also @DanielSank I guess

Maybe also @AngusTheMan

Ugh

Shouldn't read topology when I'm this tired

Today, in my topology 1 lecture, we talked about surgery on 3-manifolds :D

the best surgery manifold is the Loch Ness manifold

$\Bbb R^2 \# T^2 \# T^2 \# T^2 \# T^2 \# T^2 \# T^2 \# T^2 \# T^2 \# T^2 ...$

Why? :P

Because it looks like the loch ness monster

horned sphere is nice too

lol

one star was missing there

Randall is a madman

@ChrisWhite See? It's so obscene you don't even know it!

@ACuriousMind Is it this buggy on purpose?!

@Danu Buggy?

It moves very smoothly for me

Well, yes, it's not a physics simulation :P

I went right first

Yes.

It got boring to me after about 30 seconds (first completion)

@ChrisWhite lol

@Danu Are you joking or are you actually playing the game?

It told me I found all the coins?

lol

You don't understand xkcd, do you? :D

meh

I see

But it's still not that interesting to me

@Danu :'(

Multiplayer hoverboard game, perhaps with lightsaber PvP? That would obliterate productivity.

lol, anyone went into the water and found the way out?

@ChrisWhite There doesn't seem to be anything there, not even birds or something

@Slereah funny, whered you get it? reminds me of one of my fave books, wheres my jetpack by wilson

Everybody is fantastic at advanced physics, how about their atwood machines though? Can they write down the answer just simply by looking at an Atwood's machine without doing any work?

So this short pdf scribd.com/doc/5046604/… points out some cool tricks, but when people think about it, it seems to confuse everyone I've asked, make sense?

The issue is, how do you go from setting up two different $F = ma$ equations, to an equivalent $T = Mg + Mg$ or some twist on this, and how do you look at the picture and just know the acceleration in every case? Most confusing, how do you motivate using the reduced mass without doing any work/calculations?

@TheDarkSide I don't think I have any irl enemies. I'm pretty sure this is a user who was writing a lot of bad answers; I commented on their flaws, and now this person is upset.

@ChrisWhite fooing?

@Slereah: A kindred spirit?
