@Zhe It needs the http:// in front of the link to recognise it as a link, I believe.

OK. Thanks.

@Ramanujan hi

Ramanujan

How do we solve it?

DHMO

I know nothing about wave functions

Ramanujan

Really?ok

user228700

03:32

@Ramanujan Pretty sure it's not there in syllabus.

user228700

Anyway, have I asked here before about Van der Waals equation for real gases and how the corrected pressure is actually more?

user228700

I feel like I may have :|

user228700

Is anybody here familiar with the term compressibility factor?

user228700

Nvm.

Ramanujan

04:06

@Kaumudi in my textbook there is some strange equation and I guess it's based on that,but thanks for letting me know that it is not in syllabus.

user228700

04:22

@Ramanujan Do u mean this:

user228700

^ Schrödnger's wave equation.

user228700

(a.k.a: Stuff not in syllabus)

user228700

Might be a comprehension question.

user228700

Hey @DHMO: About those critical constants...did u come across the correct definition?

DHMO

04:27

@Kaumudi no idea

user228700

Huh. It's kind of more than just what it sounds like.

user228700

A little more complicated, I mean.

user228700

Anyhoo, I'll tell u when I find out?

DHMO

sure

Q: Help classifying some molecular orbitals after Hartree-Fock calculation

I have done a Hartree-Fock (HF) calculation on a dioxetane molecule with one methyl group on one of the C-atoms (Fig 1), with minimal basis (using Molcas). I want to identify the active space that will be used in later CASSCF calculations on the same molecule. The interesting molecular orbitals (...

@AaronAbraham oh lol you actually did it haha ;)

P.S let's not fill up the comments section with our banter

Aaron Abraham

11:09

@getafix I'm a man of my word, 'course I did "it" ;)

@getafix Agreed

getafix

so how goes

Aaron Abraham

@getafix Perhaps you could repay me in kind? 3:)

getafix

certainly

Aaron Abraham

@getafix It just....keeps going.... (P.S- Gimme a while and i'll 'do' your questions too ;) 0

getafix

probably not a good idea to spam upvote though

haha

Aaron Abraham

11:13

Whew...

@getafix so how do you know about NCERT textbooks by the way?

getafix

I studied from them

I did my HS in India.

Aaron Abraham

Oh, which state are you from?

getafix

new delhi

Aaron Abraham

(Currently doing my HS there :P )

Union Territory ._.

I'm from down south, 'God's own Country' ^_^

@getafix So how's Japan? ._.

getafix

Japan is nice, I guess

I hate my university

actually I hate my dept. they are assholes..can't speak for the rest

Aaron Abraham

11:22

@getafix Which is?

Aaron Abraham

Whoa...bad experiences?

getafix

lots

Aaron Abraham

11:23

Ah...won't ask further...

What're you specialising in?

Physical Chem. ?

getafix

yeah, I mean I don't mind talking about..not right, ask me some other day if you're really interested lol

umm I am interested in supramolecular chemistry

Aaron Abraham

@getafix Not my thing...yet ._.

getafix

and nanoscience

Aaron Abraham

Oooh, that one's interesting ;)

getafix

and of course, I love theory..so phys chem, quantum etc.

not that I am great at it, but I would like a firm grounding in it

Aaron Abraham

11:27

Phys. chem is kinda...bleh. You did CBSE I guess, so you know the textbooks cover alot o' topics in a pretty crappy way XD

getafix

yeah, they're not that bad..they could be better

they give you a solid start..

Aaron Abraham

A lot better...

@getafix To an extent ._.

getafix

the fact that they make you ask so questions is good in its own way..

Aaron Abraham

Also, the print quality is absolutely pathetic -_-

@getafix You're kinda right there :/

getafix

well they work on a shoestring budget, so I wouldn't be too harsh on them

I am guessing they still cost next to nothing?

Aaron Abraham

11:30

XD

@getafix D'ya mind if I ping you for phys. chem doubts I can't get solved? (Like for that ebullioscopy question? )

Every once in a while...

getafix

yeah, I don't mind

Aaron Abraham

O:)

getafix

just don't expect an instant response

Aaron Abraham

@getafix Sure!

getafix

yeah dude, it is okay don't worry about it too much

take it easy

Aaron Abraham

11:36

@getafix Nah it's fine...

After all, you do provide good answers to the questions that nobody else would touch.

(Mainly phys. chem)

So I'm fine with it actually ;)

getafix

@orthocresol as a moderator can you change the colour of the icon that appears next to the review button? Brown with a white number on it, kinda looks ugly imo..

Q: Van der Waals real gas equation

Van der Waals corrected the ideal gas equation for real gases and gave the following equation: $$\left(p+\frac{an²}{V^2}\right)\left(V-nb\right)=nRT$$ I’m very confused about one aspect of this equation, which is this: why add the pressure term but subtract the volume term? Edit: If somebody c...

@orthocresol Yes :-P I was asking if I had asked anybody here.

Probably not.

@Aaron @getafix Serial upvoting is actionable offense. ಠ_ಠ

You can even get suspended for it

So it's a no-no

@AaronAbraham ?

getafix

@M.A.R. Go easy on us man, plus the answers I voted in deserved them so it should be okay. Anyway, first and last time

M.A.R.

@getafix Heh, I'm a nobody. There are scripts that detect this, reverse it, and alert things to mods

I know your answers deserved it, and I know you're not Aaron's sock or the vice versa.

But the scripts don't.

Basically, voting for the person, rather than the content, is not allowed.

By that I mean like going to a user's profile page and upvoting a bunch of good answers because you like that user.

Mithoron

@M.A.R. o/

M.A.R.

So if I come across 100 of @Mart's answers eventually and upvote them, this is not fraud.

It doesn't mean I'm his sock. ~~It means he's my sock.~~

@Mithoron \o

Mithoron

Staying vigilant :)

M.A.R.

14:13

But if I upvote Mart's 100 answers in a short time, it will be detected and reversed.

Actually there's the vote limit, but it's allowed not to have a limit when imagining.

And all this time I wonder if @get is listening to me

Martin - マーチン

@M.A.R. but you have not upvoted 100 of my answers... get to work puppet!

M.A.R.

@Martin-マーチン Wait, it's the other way around.

Have you become sentient?

YOU'RE my bot, not me your.

Martin - マーチン

Hmmm... how can I be your bot when I was here first?

He just had the foresight.

getafix

@M.A.R. I am listening to you, don't worry. ;)

M.A.R.

I wanted to see how it looked like. For testing purposes

getafix

I'm also walking and it is incredibly cold and is rather have my hands in my pocket

M.A.R.

@getafix Type with your tongue

getafix

And yeah point taken, I made a comment in jest, and Aaron actually did end up up voting a bunch o my answers and naturally, I felt obliged to do the same. And of course they deserved it

M.A.R.

Of course they did, that's not the point.

getafix

@M.A.R. If only I were that good, the women would love me

@M.A.R. Yeah I know, I get your point :) I'm just offering a justification lol

M.A.R.

14:27

The very fact that you upvoted his/he upvoted yours, rather than you upvoting a random answer of his when your eyes catch it and he upvoting yours when his does makes this wrong.

getafix

Not a good one

M.A.R.

BY DEFINITION, it's wrong.

You might have upvoted them in the long run.

getafix

Yeah I get it. It's cold. Wait let me get home

Oymyakon

Oymyakon (Russian: Оймяко́н, pronounced [ɐjmʲɪˈkon]; Yakut: Өймөкөөн, Öymököön, IPA: [øjmøˈkøːn]) is a rural locality (a selo) in Oymyakonsky District of the Sakha Republic, Russia, located along the Indigirka River, 30 kilometers (19 mi) northwest of Tomtor on the Kolyma Highway. Oymyakon is one of the coldest permanently inhabited locales on the planet. == Etymology == It is named after the Oymyakon River, whose name reportedly comes from the Even word kheium, meaning "unfrozen patch of water; place where fish spend the winter." However, another source states that the Even word heyum (hэjум)...

Regardless of how bad a proposal it is (which is what the downvotes show)

pentavalentcarbon

Only solution is...

...post more to meta to drive it off the first page.

Not that even this would help much... Are you posting as unregistered to circumvent consequences of low quality answers? If yes then it's one of worst things you can do and waste of your and our time. — Mithoron 45 mins ago

I've seen that name before I think

orthocresol

You probably have. He has dozens of unregistered accounts, all posting rambling answers.

pentavalentcarbon

20:52

but why

What's there to gain by doing that?

even rep is pretty worthless if you think about it logically

orthocresol

No idea.. I guess he's just in it for the answering.

I've tried to read some of his answers, usually the content itself is pretty OK, just that it's poorly formatted and often somewhat antagonistic in tone.

They can probably be salvaged by editing, but finding a hero to do it is difficult. Seems like Loong edited the most recent one.
