19:01

still thinking...

0celo7

About?

Just make it your name

user218912

something to go before lord.

0celo7

First name

No lord.

user218912

I don't want to use my real name.

user218912

i'm unprofessional.

0celo7

19:02

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 ;/

Bernard Meurer

@0celo7 I'd never target GitHub

user218912

19:05

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.

0celo7

^

Wait

Who the hell is obe?

user218912

19:07

me?

0celo7

Idk who you are.

Bernard Meurer

@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

19:08

and besides you know me as obe from before.

Bernard Meurer

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

user218912

remember in 2015?

user116211

@BernardMeurer You can take help of MOT.

Bernard Meurer

@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

19:10

and is this physical chemistry or general chemistry?

user116211

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

Bernard Meurer

@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.

Bernard Meurer

19:12

@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

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

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

19:14

A nice concise post.

Bernard Meurer

@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

19:17

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

19:19

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

user116211

@obe RIP.

user116211

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

Bernard Meurer

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

19:21

I want to see what happens if I flag.

Bernard Meurer

@obe I wouldn't mind really

user218912

but you'll be gone for 30 mins :(

Bernard Meurer

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

user116211

@obe He should.

Bernard Meurer

@obe So?

user116211

19:21

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

19:22

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

19:24

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.

0celo7

19:25

@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

19:26

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

user218912

::drowns::

Bernard Meurer

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

user116211

@obe Are you in Titanic?

user218912

no?

user116211

Generally, the flood sometimes is bothering.

0celo7

19:28

wtf is wrong with you

user116211

But the drainage system is good now.

0celo7

I need to memorize these.

user116211

Trump will help India after he comes to power.

0celo7

@MAFIA36790 I doubt he will.

user116211

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

0celo7

19:29

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

0celo7

the last one is trivial.

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

user116211

@0celo7 You don't need to.

user116211

19:30

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

0celo7

what's a Poisson bracket?

user218912

be serious

user218912

you're in grad qm

user116211

^^

0celo7

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

user218912

19:32

@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 ;/

0celo7

@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.

0celo7

19:33

flagged.

user116211

Hmm.

user116211

@0celo7 :(

0celo7

@MAFIA36790 now that's horse poo

user116211

@obe yes.

user218912

LOL did you actually flag?

user116211

19:34

@MetaEd?

0celo7

yes

user218912

WHAT

user116211

DON'T BAN!!

user218912

lol...

0celo7

delete it

quickly

user218912

19:34

delete what exactly?

0celo7

the flagged message

user218912

the don't troll?

MetaEd

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

0celo7

he has like 5 seconds

user116211

Atleast ARTofCode didn't come.

user218912

19:34

@MetaEd sup

user218912

@MetaEd did someone actually flag?

user218912

or is this a coincidence

user116211

I'm dumb now.

0celo7

user218912

::sigh::

0celo7

19:36

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?

0celo7

yes

user218912

the general one?

user218912

which form of it?

0celo7

19:37

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

19:39

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

19:41

Apostol is full of typos.

user218912

which apostol?

user116211

@obe Vol 2.

user218912

calculus?

user116211

yes.

user218912

why would you read that

GPhys

19:41

Hanford:

user116211

I should sue the publishers for that.

GPhys

Livingston:

0celo7

what are these damn scribbles you keep posting?

user116211

@0celo7 Gravity waves? LIGO?

0celo7

huh

never really understood why that was important

user116211

19:44

No idea.

user218912

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

user218912

seems legit

0celo7

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

0celo7

19:51

doesn't matter if it's pseudoscience

not all science is useful or deserves to be done

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

Sir Cumference

Oh god...

the elections are getting closer and closer

this country is coming to an end

user116211

@SirCumference Trump will win.

Sir Cumference

@MAFIA36790 I don't care who wins

user116211

Clinton is dangerous.

Sir Cumference

19:57

America will lose

user116211

2 days ago, by MAFIA36790

Does Hillary's victory guarantee a nuclear war?

Sir Cumference

Don't post crap like that

Both are dangerous

user116211

@SirCumference Wait, you want commies then?

Sir Cumference

@MAFIA36790 Nothing I said implied that

user116211

So, what do you want?

Sir Cumference

19:58

I literally said this country is coming to an end

user116211

Why :(

0celo7

what a stupid thing to say

user116211

^^

Sir Cumference

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.

MetaEd

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

0celo7

20:03

Are you a b9

bot?

MetaEd

Me?

0celo7

Yes

user116211

What happened again?

0celo7

I flagged all of SC'a messages.

MetaEd

I'm not a bot.

user116211

20:04

Mute the chat for a minute.

Sir Cumference

@0celo7 Sigh...

Why tho

user116211

Where are our room owners and our mods?

Bernard Meurer

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

Sir Cumference

@0celo7 What part of that was seriously offensive?

0celo7

@SirCumference This.

Sir Cumference

20:05

@0celo7 I'm referring to Trump and Hillary

user116211

Hmm.

0celo7

I know

MetaEd

@BernardMeurer This might help:

chat.stackexchange.com/faq#about

0celo7

You shouldn't say things like that.

Sir Cumference

Please talk diplomatically and stop taking things so personally

Bernard Meurer

20:06

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

Sir Cumference

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

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.

0celo7

@SirCumference wtf

who you think you are

Bernard Meurer

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

20:08

From what?

Sir Cumference

@0celo7 Someone who flags logically

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

0celo7

wow I'm so offended right now

Sir Cumference

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

0celo7

stop attacking me

Bernard Meurer

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

user116211

20:10

@BernardMeurer O-?

Sir Cumference

In any case, the debate itself turned into personal attacks

MetaEd

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

Sir Cumference

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.

Sir Cumference

@MAFIA36790 Well, we were originally talking about that

user116211

20:16

Start with a clean slate.

Sir Cumference

All right

MetaEd

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

20:17

Also Physics; that's implied.

Bernard Meurer

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

Sir Cumference

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

...

Bernard Meurer

20:18

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

MetaEd

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

user116211

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

Bernard Meurer

@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.

Bernard Meurer

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

So NO- has the longest internuclear distance?

user116211

20:20

@BernardMeurer Think yourself.

user116211

Remember electronegativity is relative.

Bernard Meurer

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

Electronegativity is not wanting to lose electrons

correct?

MetaEd

@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.

Bernard Meurer

@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

ArtOfCode

20:24

Evening, all.

user116211

@ArtOfCode o/

ArtOfCode

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

user116211

We were summoning you for long @ArtOfCode.

user116211

@ArtOfCode Sure, boss :)

Bernard Meurer

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

ArtOfCode

20:25

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

Bernard Meurer

@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

MetaEd

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

user116211

@ArtOfCode I take you as the Black Flash.

ArtOfCode

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?

Bernard Meurer

20:26

@MetaEd Did you get the reference ?

@MAFIA36790 No, famous movie from the 50's

MetaEd

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

Bernard Meurer

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

MetaEd

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.

Bernard Meurer

Yep :)

MetaEd

20:28

Anyway, back to your previously scheduled electronegativity.

Bernard Meurer

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.

Bernard Meurer

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

user116211

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

Bernard Meurer

@MAFIA36790 The trauma will make them remember better

user116211

20:32

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

user116211

Bye all my comrades.

Bernard Meurer

@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.

Bernard Meurer

@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

20:34

silently hibernates the laptop...

Bernard Meurer

@MAFIA36790 Thanks a bunch, see you later

Sir Cumference

@obe You changed your name again?

This is gonna get confusing

Mikhail

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

0celo7

Ok wish me luck

About to fail

Emilio Pisanty

20:53

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

0celo7

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

Emilio Pisanty

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

@0celo7 mathematica

David Z

Yeah, it would take a while

Emilio Pisanty

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

David Z

20:56

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

Emilio Pisanty

On the other hand, I suspect that all this effort will just go into a pretty unsung answer
