Wow, I can re-delete deleted messages

goes off to sandbox to try out mod powers

For something that sounds so boring, IUPAC rules are actually interesting!

Q: Do trees really get a large volume of their mass from the carbon in the air?

I remember hearing that trees and other plants actually obtain a large amount of their mass from the carbon floating in the air, not the ground beneath them. Does the makeup of air actually contain enough carbon to support this theory, and is a tree's surface area actually large enough to obtain ...

@Fx Xactly

close, ask bio mods

F'x

@Manishearth what do you mean "close"?

Manishearth

@Fx close the question

F'x

@Manishearth ah, interesting… my opinion would be: keep it :)

Manishearth

Hmm...

It is good

F'x

9:49 AM

there's as much chemistry in it as there is biology, to be honest

Manishearth

Hmm..

F'x

if I were to ask it, I'd go on bio, but I don't think it hurts here

Manishearth

Reopened till we get consensus

Yeah, I agree with that

I guess it falls within the true overlap

F'x

@Manishearth oh, you had closed it?

Manishearth

Yeah, though I was going to ask you two/meta afterwards

F'x

9:50 AM

let's try to discuss here on these issues of scope

or meta

Manishearth

here=chat?

F'x

@Manishearth yeah, that way some other regulars can chime in

Manishearth

I closed it since the flag thingy gave me no other option (either that or "no action required")

F'x

or meta if we feel it's not a localized issue

@Manishearth meh?

flag lets you do whatever you want: ignore it for now, dismiss it, act on it, …

Manishearth

Guess it could have been dismissed as helpful

F'x

9:51 AM

@Manishearth flags don't need to be handled at a second's notice

Manishearth

@Fx The "dismiss" box said "no action required"

@Fx Aah

Fabian

@Manishearth no action required just gives you the option to dismiss it. You might still do other action like commenting on it

@Fabian Ohh

hi @Fabian

Hi

9:54 AM

Hello

Hey, @fabian, did you see my message on bio chat?

Fabian

@Manishearth Yeah I did, though I don't think adding feeds to a dead chat rooms does any good

Manishearth

Oh :(

18 days later didn't notice that :/

F'x

hum, I got Civic duty and Strunk and White in the same day…

cool afternoon in the garden with my laptop :)

Manishearth

Alright, I think we ought to keep the question

@Fabian thoughts?

Fabian

I'd consider it a biology question

F'x

9:59 AM

@Fabian enough to migrate?

Fabian

@Fx Probably yes

F'x

you're breaking a tie, Manishearth thinks it's not really chemistry, and to me it's in the overlap

Okay @Manishearth, go ahead and use your superpowers :)

Manishearth

@Fx Migrate?

Via the close box of via admin?

F'x

@Manishearth yes, we have a bio mod in favour

Manishearth

Did that do it?

Fabian

10:04 AM

@Manishearth No, just vote to close as off-topic and there select a new destination

Manishearth

Yeah, did that--no visible effect

(you have to accept it, right?)

Fabian

no

Manishearth

Hmm, looks like a bug

done now

I did the same thing a minute ago--all I got was a little popup (like the "explain your downvote" one) that said "close". O_o

F'x

@Manishearth no, they don't have to accept it, but if the destination mods vote to close it, the migration is rejected

Manishearth

Aah

Alright, new question, kinda a test question about obscure notations as I think I can guess the meaning

0

Q: What does this notation mean?

I am currently reading the CRC Handbook of Phosphorus-31 Nuclear Magnetic Resonance Data by John C. Tebby (CRC Press, 1991) and on several figures (ex. pages 9 to 14) there is a caption that reads along these lines $^{31}$P NMR chemical shifts of three coordinate ($\lambda3 \ \sigma 3$) phosp...

Q: Policy on linking to papers?

Should we have a policy on how to link through papers? For example: Should we always link via DOI number? I ask as I have been given an answer that links to a PDF, instead of via DOI. The complicating factor I realized, is that while DOIs are much more stable and reliable, the ACS page in this ...
