@JohnRennie Wokaaay, I see. To be clear though, I don't exactly enjoy the "Verse-chorus-verse-mix things up-ending verse with small changes" design of most of the pop songs these days either.
 
For example the track Supper's Ready on side 2 of the Genesis album Foxtrot is 22 minutes long. But you'll find it has many different sections that break it up.
FWIW I think Supper's Ready is the single greatest work of progressive rock that has ever been written.
 
user228700
Yeah, but see what I'm saying is, if u have that much to say, just split it into different songs! 22 minutes is just way too long--I can't keep up with it for that long and still feel really amazing at the end. I've always sort of been annoyed that I feel this way 'cause as u say, there are loads of excellent music that are much longer than just 6 minutes but yeah, for some reason, this is the way it is, for now :-( Maybe I'll grow out of it.
 
user223506
@JohnRennie I am keen to answer this physics.stackexchange.com/q/292337/140434 - it's edited to be more refined now
 
@Doc there is a temptation to think that because we can write a great answer the question must be good, but that isn't the case. Atmospherioc chemistry is a fascinating subject. I did a course on it in my final year and it's long been something I wished I had the time to study more fully.
 
user228700
I think I've asked this question before but I don't think the answer was satisfactory. This is what my textbook says regarding electronic configuration in molecular orbitals:
 
9:06 AM
There's probably lots of interesting stuff to say in an answer about atmospheric scattering.
However at the end of the day that isn't a great question.
If it was asking specifically about scattering mechnisms it would be on topic, but it isn't.
However I don't feel very strongly about it, and if the question started getting reopen votes I wouldn't vote to leave it closed. However at the time of writing it doesn't have a single reopen vote.
 
user228700
> "The molecular orbitals like the atomic orbitals are filled in accordance with the Aufbau principle, the Pauli Exclusion principle and Hund's rule of maximum multiplicity. But the filling order of these molecular orbitals is always experimentally decided; there is no rule like the $(n+l)$ rule in case of atomic orbitals, for molecular orbitals."
 
Note that I have to special powers to reopen. A reopen vote from me would just be one of the five reopen votes needed to reopen the question.
 
user228700
What do they mean by this?
 
The occupation rules in atoms arise from the spherical symmetry that atoms enjoy.
 
user228700
What dyou mean by "occupation rules"?
 
user228700
9:10 AM
Oh, all those rules I just mentioned? OK :-P
 
The rules for occupation of atomic orbitals by electrons.
 
user228700
OK...
 
@Kaumudi.H That's true, MO occupancy is highly sensitive to the chemical environment, hence the type of bonds, the symmetry of the wavefunction, and sometimes even the solvent
 
user223506
@JohnRennie ah but this question is about the physics of UV radiation attenuation and scattering - I did my physics PhD on this.
 
user228700
@Secret Is this advanced stuff?
 
9:12 AM
Molecules have reduced symmetry, sometimes much reduced symmetry and that means there aren't any general rules for the order of occupation of molecular orbitals.
 
user228700
Huh. Okay, is this stuff too advanced for say...a high-schooler to be thinking about? I don't understand why the heck my textbook drops these random fact bombs and then never explains itself. And then I ask here and realise that it's too complicated and that I don't even need to venture to that stuff.
 
This is why predicting chemical bonding for anything other than simple systems is so hard and require us computational chemists, because the interactions between different groups and the environment is so important that they influence the shape and orientation of MOs in the molecule hence the electron distribution
 
@Doc I've voted to reopen. If you vote as well that's 2 of the 5 reopen votes needed. I wouldn't hold your breath though.
 
user228700
@Secret Wow, I see.
 
However, without going to such advanced stuff, you still need some basic MO theory such as ligand field theory for metal complexes, and frontier MOs to explain them
 
user228700
9:14 AM
Well, OK then, I'll just accept that and move along. Thanks, guys :-)
 
user223506
@JohnRennie alas I not have the rep to repen
 
user223506
reopen even
 
so they are kinda uni level stuff in context. I am pretty sure your MO theory go as high as main group chesmitry and bimolecular compounds
 
user228700
@Secret What dyou mean?
 
@Kaumudi.H (I am not sure of your book's, maybe you can tell me the scope of MO theory your book covers?) Usually, MO theory in hgh school will cover topics such as bonding in O2, F2, N2 molecules and their ions, simple pi and sigma bonding scenarios and some covalent bonding in main group chemsitry such as the BF3 (e.g. anything not a transition metal)
 
user228700
9:16 AM
Oh, right, yeah, it covers all that stuff :-)
 
does it cover more than what I stated there?
 
user228700
Not really, no.
 
user228700
I never learned more than that in high school but this textbook is messed up and my portions are vast so yeah, I'll know for sure as I proceed...
 
...so anything more advanced than that, you need those aforementioend principles, and as Johnrennie allured to, to get even higher you need to know about the symmetry of the molecule (that covers group theory and character tables), and finally for research level stuff, you need to calculate them using quanutm chemsitry software or do high precision spectroscopic experiments to check the molecule energy levels and molecular quantum states

In short, I think for that point, you just need to be aware that MO is complicated business is enough
 
user223506
@JohnRennie I did very similar with my PhD
 
user228700
9:19 AM
@Secret Lol, okay, thanks :-)
 
user223506
(the topic that is, not the reopen queue)
 
Right, if there aren't any outstanding physics questions I'm going to make a coffee and watch Kaumudi's food video.
 
user228700
@JohnRennie :-) Tell me if u like it (Also, it's not my food video. A person walks around in my city and eats stuff and I found the video, that's all :-P)
 
user228700
BTW, I was about this close to running into the CEO of Google these past few days.
 
user228700
Sigh, is literally nobody even remotely intrigued by that?
 
user223506
9:27 AM
Awesome!
 
user228700
The long and short of it is that Sundar Pichai's family lives about 1 Km from where I live and these past few days, he was here, visiting his 92 year-old grandma so in theory, I could've randomly ran into him on the streets, however unlikely that sounds. He's a nice person, he may have stopped to say "Hi" back :-P (In response to my "Aaah, you, ohh!")
 
user223506
@Kaumudi.H that'd be awesome!
 
My family once live near 2 pop stars (abeit the ordinary HK ones, not the international acclaimed stars) and they often told me on some of the things they observed. One of them is seen moving many boxes one day
 
user228700
@Doc Yeah, it would...for some reason :-P
 
user223506
@Kaumudi.H If I saw someone like Elon Musk, I would probably start bowing and holding onto his ankle

user228700
@Sec: Are u busy? Can u help me with something that's been bothering me for God only knows how long now? It's a quick question...well, sort of. I'll try my best not to be dumb, I swear.
 
just ask, and I will see what I can do
 
user228700
Okay, thanks. Um, so again, I feel like I may have asked this before but can u help me to understand this paragraph:
 
user228700
Hang on, I will highlight some sentences...
 
user228700
 
user228700
9:41 AM
What do they mean by "symmetry axis"?
 
For a diatomic, if you drew a line between the two nuclei and then rotate the whole molecule about that line, you should get no change in the orientation of the molecuel at all (think rotating completely spherical kebabs)
 
user228700
::Googling kebabs::...
 
user228700
Oh, right, okay...
 
user228700
But in case of $\pi$ bonds, when u do the little rotation, it changes 'cause the + and - lobes are now on different sides than before..?
 
yes
For more details, see here:

Q: How to determine gerade & ungerade symmetry of a MO orbital?

user276738J.D.Lee writes in his book Concise Inorganic Chemistry: [...] An alternative method for determining the symmetry of the molecular orbital is to rotate the orbital about the line joining the two nuclei and then rotate the orbital about the line perpendicular to this. If the sign of the lobes r...

 
user228700
9:47 AM
Oh, okay. Thanks very much _/\ _
 
user228700
(And I'm sorry for the trouble :-/ Would u prefer it if I were to not ping u for questions?)
 
@Kaumudi.H hmm, that video didn't cover that many different foods.
 
user228700
@JohnRennie I...don't know about that. It sort of did.
 
The previous one you posted was more comprehensive.
And I can't believe he went into a sweet shop and didn't try the gulab jaman. Sacrilege!
 
user228700
Yes, I guess that's true. To be fair, he probably didn't have a good guide. Those foods are far from the classic foods that one craves to eat in Madras.
 
9:50 AM
One of this things that struck me in Pune is that meat is always served with the bone. In the UK it's always served with the bone removed. (Not that this is relevamt to you! :-)
In the restaurant he went to I noted the meat was on the bone.
 
user228700
The iconic foods of Madras (a.k.a Chennai) are... Medu vadai, Filter kaapi (coffee), Sambar sadham (Sambar rice), Puliyodhare (Tamarind rice), Masala Dosa...
 
user228700
Did I tell u, @JohnR: About the food tour that I went on with my friend?
 
user228700
@JohnRennie Ah, I see...no, it's not relevant to me; I don't even know how to notice these things :-P
 
@Kaumudi.H no ...
A food tour sounds good :-)
 
user223506
@JohnRennie oooooooooooooh yeah!
 
user228700
9:54 AM
Well, we'd had many many plans of properly hanging out after The Summer of Entrance Exams but she was leaving early for college.
 
user228700
@JohnRennie Yes, that :-) Yummm.
 
user228700
Oh, also, paniyaram.
 
Tamarind I can take or leave ...
 
user228700
Anyhoo, she was leaving too soon so we spent about 3 hours on Zomato, planning our food tour of sorts.
 
user228700
9:56 AM
We weren't able to cover the whole city but from morning till evening, we were out in the city, walking/taking buses from one shop to the next.
 
They should make genus 2 vadas too.

I plan to go on another food tour in June so @DanielS, @JohnR tell me if u're interested to see some more pictures :-P

@JamalS Since you edited this, did it actually make any sense to you? I know all the words but the way they are arranged just looks non-sensical to me.
 
@ACuriousMind No, it doesn't make sense to me but I edited it because I can't stand ugly LaTeX.
 
Fair enough :D

@DanielSank, just reached 18 - mwahaha =)

oh no someone downvoted me!?! >_<
why oh why
 
@heather welcome to the world of woes
 
@AccidentalFourierTransform on what?
 
for the record, my answer was flawless
 
@BalarkaSen I think she means hats, not age ;P
 
oops
 
3:04 PM
yup, i'm a few years behind 18 =P
and i certainly can't drive yet
 
I like walking
 
i'm on the shorter side, though thankfully i've grown enough that i won't need to use a phone book to see over the steering wheel
@AccidentalFourierTransform ::shakes head:: great answer +1
oh, @AccidentalFourierTransform, were you around when we were describing users and what kind of furniture they were?
 
lol, thanks for the nice words (and for the internet points) ;-)
@heather no, but that sounds like fun :D
 
3:09 PM
here, let me find it
Dec 31 '16 at 20:43, by DanielSank
I feel like you're part of the furniture around here.
there we go, it starts there
but if you'll scroll down a bit there's a particularly funny comparison
and then I got a response in the form of an....awkward comment.
 
I'm a desk, great.
 
2 days ago, by heather
@DanielSank, also, awkward moment of the day here
@ACuriousMind that's a good thing =)
oh no, the comment got deleted =/
 
ok i want to be this
because im pretty but useless
 
that's not true ::shakes head::
though your cat is pretty awesome
 
3:32 PM
How do we know that's a cat, btw? Has someone reversed the Fourier transform and examined the resulting animal?
 
@ACuriousMind: this is the direct result of all those QFT questions I was hassling you and Daniel with a while back. It's all your fault :-)

Q: What is the minimal number of point charges required to model an electric octupole?

Emilio PisantyIn an answer to this question, I showed that a general electric quadrupole can be modeled by a combination of seven point charges (or possibly less if one or two of the principal quadrupole moments is zero, or if they add to zero). This is likely the minimal number, or at least it is likely to be...

@JohnRennie I can live with that ;)

A: Two sets of coordinates each in frames $O$ and $ O' $ (Lorentz transformation)

user82794The answer is YES. It's true that the coordinate system (u′,v′,w′) is related to (x′,y′,z′) also by the orthonormal matrix A, at least under the Lorentz Transformations used in the following. But please, let use other symbols (for example it's custom to use $\;\upsilon\;$ for the algebraic magnit...

yes, that's true. the second longest is

A: Does alternating current (AC) require a complete circuit?

WetSavannaAnimal aka Rod VanceYou're actually hitting on a very famous concept here that revolutionized physics!! Your understanding is almost wholly correct and your analogy is a good one - excellent reasoning - the only thing missing is radiation from the system. This latter lack is mostly irrelevant for the level of quest...

 
@ACuriousMind I've long believed there is an eager market for explanations of what QFT does i.e. explaining the principles without the maths but also without oversimplifying, and I'd say the voting on that answer backs me up!
The next target is to write an answer in that style that explains what virtual particles are. That, however, may take me a while :-)
 
@JohnRennie It's certainly better than most other non-mathy writing I've seen on this topic.
 
"what is a virtual particle" would probably get closed as too broad.
 
@heather It's not too broad. In fact, I can give you a one-line answer: It's an internal line in a Feynman diagram.
 
3:44 PM
And I think we already have such questions
 
well, then, nevermind =)
 
But I personally have no intuitive feel for how virtual particles make their appearance in QFT, and that's something I would love to understand.
I know they appear in the calculations used to calculate scattering probabilities, but I have no feel for what they are being used for.
And I suspect if I can come up with an answer along the lines of the one I mentioned above that would be another big scorer!

Q: Can virtual particles be thought of as off-shell Fourier components of a field?

knzhouI just found this blog post, which gives an interpretation of virtual particles I haven't seen before. Consider a 1D system of springs and masses, where the springs are slightly nonlinear. A "real particle" is a regular $\cos(kx-\omega t)$ wavepacket moving through the line, where $\omega$ satis...

^that was also a nice discussion which exhibits that one issue is that people might actually be talking about different things when they say "virtual particle"
 
:: John settles down to read ::
 
one day I will write a book on QFT that wont mention any of "virtual particles", "creation/annihilation operators", "bare parameters", "path integrals", "interacting picture", "running couplings",...
what else?
maybe even "gauge invariance"
idk, ill be fun
 
3:49 PM
Why no path integrals or c/a operators?
 
path integrals are always used as an excuse to simplify the analysis of complicated problems
e.g., derivative interactions
 
Also, why no running couplings?
 
you can do it with operators, but it is more cumbersome
also, I hate creation/annihilation operators and Fock spaces
well, maybe running couplings
yeah, I will use those
 
Yeah. Why choose the more cumbersome route? You won't really be more rigorous in the standard operator formalism, so why bother?
 
because I don't like when books change the rules of the game halfway through.
you do everything either with path integrals or with operators
 
3:51 PM
I do wonder why so many start with the operator formalism
probably because it's what you usually use in QM
 
ok, so after writting my book, Ill write another but using only path integrals ;-)
well, it does have a feel that you are doing something more rigorous
after all, every approach to AQFT is with operators
 
Yes, but unless you get really technical and care about all the domains and well-definedness and introduce the operator-valued distributions, you aren't more rigorous.
 
I know, but at least it has the potential to be
 
@AccidentalFourierTransform Sure, because the rigorous path integral approach is usually called constructive QFT, not algebraic QFT ;)

Alas, there hasn't been much progress on it in dimensions higher than 3 that I know of
@AccidentalFourierTransform never
 
(BTW how is "Undersanding typical non-perturbative calculations in QFT" still open? it is blatantly too broad, even acknowledged by OP)
 
The close review is underway, but it needs more reviewers
Only 2 reviews so far
 
ok that makes sense
BTW2: I was trying to google a certain thing I had in mind but I dont remember the proper terminology nor any key word
maybe you know how it is called
(I thought that it was a wigner contraction, but apparently not)
and I don't remember the details either
 
@ACuriousMind close review? more reviewers? is there a backlog?
::goes to look at queue::
 
@ACuriousMind it was something about how a relativistic system in $d+1$ dimensions is equivalent to a non-relativistic system in $d$ dimensions
you take $p^2=m^2$ in $d+1$, and write everything in light-cone coordinates,
 
3:59 PM
@AccidentalFourierTransform Write a book on $(\infty, n)$-categories instead and mention at the last chapter that everything in the book before is actually quantum field theory.
 
the Wigner contraction would be the transformation that "contracts" the Poincaré group to the Galilei group
 
$2p^+p^-=\boldsymbol p^2+m^2$
 
@AccidentalFourierTransform link?
 
and then solve for $p^-=\frac{\boldsymbol p^2+m^2}{2p^+}$ and then take $p^+=m$
and you get $E=\frac{\boldsymbol p^2}{2m}+\cdots$
 
I'm not sure whether I've seen that
 
4:01 PM
Ah it really was Undersanding - I had corrected what I thought was your typo when searching :-)
 
In any case, I don't know how it's called, either
 
@BalarkaSen wat
I dont' know what any of what you said means =P
@ACuriousMind crap
ok, thanks anyway

whats a 10th grader? how old are you?
 
i wanna become like elon musk and mark zukerberg
15
and im gonna open a company too
heck i would become better then them!!
im just worried that
 
well, 10th grader american is like 15-16 @AccidentalFourierTransform
 
11th grade studies is like a whole new level

@heather ok, thanks
 
im indian :/
 
oh, nvm then =)
 
i mean i WILL understand and get everything that they are teaching
but i dont know if i would get the time to complete the course
i have this thing where i want to understand every concept as deeply as i can and clear every doubt that i have
but that takes time
 
shoot for the moon I guess
 
things that others can learn in 10 min..it takes like hours for me as i have so many questions..
and im nervous if i take that much time
if i would have enough time in 11th and 12th
well but im gonna try nevertheless :P

how old r u?
 
twentysomething

but Sir Rennie is not, never was, and never will be.
@MartianCactus banned: allowed to view conversation but not participate.
 
its quite surprising that most of you are like professionals in physics and stuff
like REAL professionals

yeah, sure. but there's also college students studying physics and people who just love physics and people from all backgrounds.
 
I am certainly not either - Im twentysomething and I don't even know what a Penrose diagram is
 
I'm retired. I was a colloid scientist, which is only partly physics.

Well we all started there.
 
@JohnRennie Here it seems that we just brush over the topics.
 
I take it here doesn't mean this site?
@Kaumudi.H Using the wi-fi is the better solution if the speed is OK

@JohnRennie "Here" means at my particular school and/or same level schools at my country.

@JohnRennie 75 Mbps...for now.
 
@Kaumudi.H OK. Usable but not great. You probably won't be downloading many blurays :-)
 
@JohnRennie Like i've been thinking if same lvl schools at different countries would be able to provide more.
@JohnRennie But yeah.
 
@LuBu There's nothing to stop you going into things more deeply in your own time if they interest you.

Whoops, mbps not kbps! :-o
 
4:43 PM
@Kaumudi.H, downloaded a blu-ray, eh? =)
 
user228700
@heather Nope :-P
 
user228700
I should get to bed. Bye, everyone :-)
 
Goodnight
 
oh, okay
Goodnight @Kaumudi.H
 
@JohnRennie That's what i try to do/would like to do, but then there's this mess of subjects and you don't rly know in which order you'd like to learn about certain things.
@JohnRennie So atm i'm just reading the books assigned to my lvl. But my point is that sometimes it just gets really boring, because these books are probably just supposed brush over the topics and sometimes it might just get too abstract.

@JohnRennie But im not saying that physics is boring, just that the studying is boring =).
 
I'm not sure I understand the distinction "X is interesting but learning X is boring".
Unless by "studying" you mean some sort of specific learning that is imposed on you by an imperfect education systems and not the general study of the subject
 
Well, understanding something is obviously fun, but putting in the effort to understand it might be boring.
 
I don't think that "boring" is the word you're looking for. Maybe "hard" or even "tiresome", but not boring :-/
 
5:47 PM
Yeah, maybe tiresome is the right word.
 
@Kaumudi.H I think. Want to test it? :)
 
in case anyone is interested, here is what the real space cat looks like:
 
ooh, very nice
 
Looks like lines to me =).
 
I just lost a lot of time on an improvement of Landauer's bound proof with the wrong sign -_-
 
5:58 PM
I just wasted a lot of time trying to find what the Fourier transform of a wavy cat looks like

@AccidentalFourierTransform but you are still a failure
you still dont know the Penrose diagram
;-;
