About?

Just make it your name

user218912

something to go before lord.

First name

No lord.

user218912

I don't want to use my real name.

user218912

i'm unprofessional.

7:02 PM

We all know it.

user218912

well you do.

user218912

anyway IceLord was pretty cool :P

user218912

idk why I changed it

user116211

@bl00 Now you are saying that ;/

@0celo7 I'd never target GitHub

user218912

7:05 PM

oh what if I just change back to obe, like last year.

user218912

done xD

user116211

@obe WTH ;/

user218912

what? that was my name for the longest time.

user116211

Anyways, let it off.

^

Wait

Who the hell is obe?

user218912

7:07 PM

me?

Idk who you are.

@MAFIA36790 Can I justify the fact that Ar is a monoatomic gas by it's very high ionization energy?

user116211

@BernardMeurer sure you can.

user218912

@0celo7

user218912

Oct 7 at 23:50, by bloo

fuck do we have to go through this every time I change my name?

user218912

7:08 PM

and besides you know me as obe from before.

The question is literally "Justify why Ar is a monoatomic gas"

user218912

remember in 2015?

user116211

@BernardMeurer You can take help of MOT.

@MAFIA36790 MOT is too much work for this, no? Just saying that it has a fully filled valence thingy and that causes it to have uber high ionization energy which makes it bonding unlikely, implying it will behave as a monoatomic gas

user218912

@BernardMeurer what book are you reading?

user218912

7:10 PM

and is this physical chemistry or general chemistry?

user116211

@BernardMeurer Think if there is any anti-bonding orbital in the configuration of Ar.

@obe On Chemistry? None, though I should be reading Cheng

@MAFIA36790 Nope

@dmckee Are you here to save me (please be)

user116211

Well, then.

user218912

@BernardMeurer read mcquarrie physical chemistry.

user218912

it will answer all your questions and more.

A: Are ther known compounds of Argon? What is their molecular geometry and hybridisation?

7:12 PM

@obe Exam tomorrow morning, no time. Thanks for the reference though :)

user218912

definitely use it for the rest of your course though

user218912

it explains all the stuff like the wave equation in 1 or 3d for atoms and molecules.

user218912

and it's not a difficult read, I read parts of it knowing only basic calculus

user116211

Read this related answer by Mart @Bernard:

user116211

Argon is a quite unreactive element, however very few compounds of it are known. The most popular, and currently the only neutral compound, is argon hydroflouride, $\ce{HArF}$, which was reported by L. Khriachtchev et.al..[1] In the same issue there is also a comment on the matter by my former ...

user116211

7:14 PM

A nice concise post.

@MAFIA36790 Nice indeed

Why would Argon want to bond though? It's already fully filled it's valence thingy has it not?

What does it gain from bonding?

user116211

Yes, Mart has a PhD in chem.

user116211

@BernardMeurer peace.

user218912

ha-ha

user116211

It's not that stuff.

user116211

7:17 PM

Read minutely.

user218912

xD

user218912

@MAFIA36790 your flags don't work though, it seems.

user116211

And now, ARTofCode will be coming again with his axe.

user116211

:(

user218912

because nobody really flags anything lol

user116211

7:19 PM

Seriously though, it was a bad use of that word.

user116211

@obe RIP.

user116211

We don't need Lumo after-all to ban him.

I fear ArtofCode more than I fear death nowadays

user116211

@BernardMeurer He is Grim Reaper.

user218912

@BernardMeurer what if I were to really flag that, would you hate me?

user218912

7:21 PM

I want to see what happens if I flag.

@obe I wouldn't mind really

user218912

but you'll be gone for 30 mins :(

I've watched the Seventh Seal, I know how to deal with death

user116211

@obe He should.

@obe So?

user116211

7:21 PM

He has an exam tomorrow.

user218912

nah I'm not a loser

user218912

ppl who flag are losers...

user116211

@obe staring at 0celo7.

user218912

he doesn't actually flag though.

user116211

I know ;)

user116211

7:22 PM

Or does he?

user116211

I don't know.

user218912

who knows

user218912

it's been raining non-stop for the past 2 days here.

user116211

Anyways, Bourbaki is really interesting to read; atleast till now.

user116211

@obe I'm jealous.

user116211

7:24 PM

I love rainy days.

user218912

I don't like wearing a coat though. :(

user116211

ohh.

user218912

it's cold too

user116211

Our university looks awesome in rainy season.

user116211

@obe I'm really jealous.

7:25 PM

@BernardMeurer I'm going to fail my QM exam

user218912

isn't rainy season in india like floods?

user218912

you like that? lol

user116211

@obe At least it's over in the Eastern part of India.

user116211

@obe kinda.

user116211

Winter is coming....

user218912

7:26 PM

yay my house and all my belongings including me are being swept away by the flood I love rainy days

user218912

::drowns::

@0celo7 What's with your eye after all?

user116211

@obe Are you in Titanic?

user218912

no?

user116211

Generally, the flood sometimes is bothering.

7:28 PM

wtf is wrong with you

user116211

But the drainage system is good now.

I need to memorize these.

user116211

Trump will help India after he comes to power.

@MAFIA36790 I doubt he will.

user116211

@0celo7 Commutative brackets? You get them the first time you read QM.

7:29 PM

I don't think he likes India

@MAFIA36790 I don't know any QM

help

user218912

@0celo7 aren't they trivial to memorize?

user116211

@0celo7 He loves Hindus.

user218912

except the last one

the last one is trivial.

i'ts just $\mathfrak{S}\{[A,[B,C]]\}=0$

user116211

@0celo7 You don't need to.

user116211

7:30 PM

If you know canonical transformations and Poisson brackets, job done.

what's a Poisson bracket?

user218912

be serious

user218912

you're in grad qm

user116211

^^

@obe erm, a lot of people in the class don't know PBs

user218912

7:32 PM

@0celo7 I once made an excuse like that for QFT and you're like, "you don't want to be the lower end of the class" or something like that.

user116211

@0celo7 WTH ;/

@MAFIA36790 we can't all be as smart as you

user116211

Don't troll.

user116211

They are taught in 1st or 2nd year of undergrad classes.

user218912

@0celo7 everyone knows you're smart af, so saying that is like making fun of him.

7:33 PM

flagged.

user116211

Hmm.

user116211

@0celo7 :(

@MAFIA36790 now that's horse poo

user116211

@obe yes.

user218912

LOL did you actually flag?

user116211

7:34 PM

@MetaEd?

yes

user218912

WHAT

user116211

DON'T BAN!!

user218912

lol...

delete it

quickly

user218912

7:34 PM

delete what exactly?

the flagged message

user218912

the don't troll?

Here to make sure it stays professional and respectful. Howdy, y'all.

he has like 5 seconds

user116211

Atleast ARTofCode didn't come.

user218912

7:34 PM

@MetaEd sup

user218912

@MetaEd did someone actually flag?

user218912

or is this a coincidence

user116211

I'm dumb now.

user218912

::sigh::

7:36 PM

that second to last one

$[A,BC]=[A,B]C+B[A,C]$?

yes

nice

I need the Heisenberg principle too

how do I memorize that?

user218912

memorized?

user218912

seriously?

yes

user218912

the general one?

user218912

which form of it?

7:37 PM

yeah

dude I don't know QM

I'm not a physicist

@MAFIA36790 did you get banned?

user218912

why would he get banned?

user218912

he didn't say anything inappropriate.

user116211

I'm preparing my Molotov cocktail and Tommy guns and my men for someone.

user218912

okay you can get banned for saying that.

user218912

better delete it since a mod is here xD

user116211

7:39 PM

I am MAFIA.

user218912

and assuming that's directed at 0celo7 he will flag it.

user116211

@obe No.

user218912

because that message makes him feel unsafe.

user116211

:(

user116211

@0celo7 You know brackets; so Heisenberg's Principle is easy then.

user116211

7:41 PM

Apostol is full of typos.

user218912

which apostol?

user116211

@obe Vol 2.

user218912

calculus?

user116211

yes.

user218912

why would you read that

GPhys

7:41 PM

Hanford:

user116211

I should sue the publishers for that.

GPhys

Livingston:

what are these damn scribbles you keep posting?

user116211

@0celo7 Gravity waves? LIGO?

huh

never really understood why that was important

user116211

7:44 PM

No idea.

user218912

yep, you read like 5 advanced GR books and never understood why it's important

user218912

seems legit

correct

I don't see why GR is important

or worth all the money they spent on LIGO

user218912

same the LHC is useless as well, what's the point of QFT?

user218912

it's pseudoscience

7:51 PM

doesn't matter if it's pseudoscience

not all science is useful or deserves to be done

user116211

Q: Your CERN Experiment

I'm not entirely sure if this is a sort of question that is "legal" on this page, but nevertheless: I was wondering, if you would be given a chance to suggest one quantum experiment that would then be put into practice at CERN, what would it be based on? What is it that you think needs more look...

quantum-mechanics

Oh god...

the elections are getting closer and closer

this country is coming to an end

user116211

@SirCumference Trump will win.

@MAFIA36790 I don't care who wins

user116211

Clinton is dangerous.

Does Hillary's victory guarantee a nuclear war?

7:57 PM

America will lose

user116211

2 days ago, by MAFIA36790

Don't post crap like that

Both are dangerous

user116211

@SirCumference Wait, you want commies then?

@MAFIA36790 Nothing I said implied that

user116211

So, what do you want?

7:58 PM

I literally said this country is coming to an end

user116211

Why :(

what a stupid thing to say

user116211

^^

People who take the presidency seriously

Literally, it was like watching three year olds argue

"You're the puppet!" "No, you are"

These are grown adults.

The beginning of the debate, I was actually relieved they were talking seriously about problems. Then it all fell apart.

Do not post personal attacks. Please keep it professional and respectful.

8:03 PM

Are you a b9

bot?

Me?

Yes

user116211

What happened again?

I flagged all of SC'a messages.

I'm not a bot.

user116211

8:04 PM

Mute the chat for a minute.

@0celo7 Sigh...

Why tho

user116211

Where are our room owners and our mods?

@MetaEd Where does it say we have to be professional here? afaik we just need to be mildly respectful

@0celo7 What part of that was seriously offensive?

@SirCumference This.

8:05 PM

@0celo7 I'm referring to Trump and Hillary

user116211

Hmm.

I know

@BernardMeurer This might help:

chat.stackexchange.com/faq#about

You shouldn't say things like that.

Please talk diplomatically and stop taking things so personally

8:06 PM

@MetaEd What do they even mean by keeping it professional? That's über vague

You'll need to learn to take other people's opinions seriously, even if they disagree with yours

user116211

Sep 29 at 9:47, by David Z

Don't use chat flags except for seriously inappropriate messages. We've had a problem with inappropriate chat flagging for a while, and more so recently.

@SirCumference wtf

who you think you are

NO, NO-, NO+, which one has the longest internuclear distance
NO+, right?
Because then O is less electronegative, and they are less interest in electron-sex

@MAFIA36790

user116211

@BernardMeurer Less electronegative?

user116211

8:08 PM

From what?

@0celo7 Someone who flags logically

If it's not personally directed towards you, don't take it personally

wow I'm so offended right now

You can't get through life shunning people who disagree with you

stop attacking me

@MAFIA36790 Between O, O+, and O-, O+ is the least electronegative?

user116211

8:10 PM

@BernardMeurer O-?

In any case, the debate itself turned into personal attacks

This room was placed in timeout for 5 minutes; All right, let's everybody take five minutes to calm down.

The lack of civility was the reason the debate was so abysmal

And that's why I don't trust these two people leading the country

user116211

@sirC stop this now.

@MAFIA36790 Well, we were originally talking about that

user116211

8:16 PM

Start with a clean slate.

All right

Do not post personal attacks.
When something definitely inappropriate is posted, do not reply. Flag and disengage.
When the overall conversation goes in an inappropriate direction, request a change of subject.
When someone makes such a request, honor it.

user116211

No politics.

user116211

No trollings.

user116211

Only Maths.

user116211

8:17 PM

Also Physics; that's implied.

@MetaEd So you're the new ArtOfCode, I see

Well, in that case. Y'all heard about the new dwarf planet we found?

user116211

To all the flaggers:

user116211

...

8:18 PM

@MAFIA36790 Do you know the answer to my question though?

@BernardMeurer Can't say. I met Art just lately.

user116211

@MetaEd He is the Grim Reaper here. We really fear him a lot.

@MetaEd The gist of it is he would come, ban people, slaughter families, set the fields on fire, pillage the houses and go back to his den

user116211

@BernardMeurer I said the oxygen anion is the least electronegative than the others.

@MAFIA36790 Oops, derp, I meant O-, yeah

So NO- has the longest internuclear distance?

user116211

8:20 PM

@BernardMeurer Think yourself.

user116211

Remember electronegativity is relative.

@MAFIA36790 None of this makes much sense to me to be honest

Electronegativity is not wanting to lose electrons

correct?

@MAFIA36790 @BernardMeurer About all I can suggest is to recognize trouble when it starts, and try to keep it from escalating. It often helps to simply distract people to a different topic.

user116211

@MetaEd Sure, sir.

@MetaEd Please, next time just do a short ban on the people causing trouble, and not freeze the whole room. It's like you're shooting the hostages or something

Oh jesus he's here

8:24 PM

Evening, all.

user116211

@ArtOfCode o/

I do hope you're being nice to my fellow moderator there.

user116211

We were summoning you for long @ArtOfCode.

user116211

@ArtOfCode Sure, boss :)

@ArtOfCode "Vem är du?"
"Jag är döden"

8:25 PM

Ah, politics, politics. Top choice of conversation - if you like the feeling of your room icing over.

@ArtOfCode I was talking crap about you if I am to be truly honest :p

@ArtOfCode But if you get that reference I'll be happy

@BernardMeurer Wait. I thought Thomas Covenant was a few rooms down.

user116211

@ArtOfCode I take you as the Black Flash.

Be careful you don't go the way of the news room, which recently had to be frozen because of people ~~talking~~ posting insulting memes about political matters.

user116211

@BernardMeurer Klingon?

8:26 PM

@MetaEd Did you get the reference ?

@MAFIA36790 No, famous movie from the 50's

@BernardMeurer Surely not. I had to run it through Google Translate even to make sense of it.

The Seventh Seal - The knight meets Death [English sub]

►

Watch the first few seconds

I've watched it so many times I've memorised some of the lines in Swedish

Oh, so Monty Python and the Holy Grail was a remake.

user116211

@BernardMeurer It is the power to draw electrons towards itself by an atom in a molecule.

Yep :)

8:28 PM

Anyway, back to your previously scheduled electronegativity.

I recommend that movie a lot, one of the few honest presentations about death I've seen

@MAFIA36790 Okay, so it increases if the atom loses an electron?

It's like if an Arab sultan has 20 wives, and now it has 19. It will want more wives even more?

user116211

@BernardMeurer kinda.

(I'd be a great chem prof for children)

user116211

@BernardMeurer Just don't use some objectionable words :)

@MAFIA36790 The trauma will make them remember better

user116211

8:32 PM

Anyways, I need to go back to my final study before calling it a day.

user116211

Bye all my comrades.

@MAFIA36790 Wait! The question!

Before you leave

NO, NO+ or NO-?

user116211

Especially @ArtOfCode and @MetaEd; good day to all.

user116211

@BernardMeurer Do it yourself; that's my order.

@MAFIA36790 I can't dude, don't you see I don't understand this?

I do not know how

It'd be easier to ride a monocycle while juggling in the current state of things

user116211

8:34 PM

silently hibernates the laptop...

@MAFIA36790 Thanks a bunch, see you later

@obe You changed your name again?

This is gonna get confusing

Mikhail

Which do you prefer, the Diffusion Equation or the Wave Equation?

Ok wish me luck

About to fail

8:53 PM

@Danu I take it TikZ is also quite capable of doing this version of the image?

Holy shit how did you do that?

David Z

@EmilioPisanty You could animate each frame in TikZ and put them together using something like ImageMagick

@DavidZ yeah, but "could" as in "if you were really into suffering"

@0celo7 mathematica

David Z

Yeah, it would take a while

@DavidZ (not that the Mathematica version didn't take a while, of course)

David Z

8:56 PM

Yeah, "a while" in the same sense as "nontrivial" :-P
