@ACuriousMind one of the only times you went on having female profile pictures was during the mod elections where you got the most publicity. did you want to screw with everyone thinking you were a girl? because I remember for a long while lots of people did think that when you became a mod.

0celo7

ACM was playing the affirmative action game

Obliv

12:05 AM

@0celo7 messed up. ACM is the coolest mod and he's like a wizard with infinite knowledge (at least to me) without him the maturity level drops like 10 points in this chat

@eulB case in point

eulB

or maybe he thought if he poses as a girl he'll get more voters because gotta promote girls in STEM y'know.

that's actually genius

0celo7

I just don't think ACM wants to see all of the gay nazi propaganda in the discord

ACuriousMind

@eulB Hmmm? IIRC, I've had Ciri, Triss, Kreia and Fall-From-Grace as female avatars at various points in time.

eulB

@0celo7 the discord is pretty clean

Obliv

@0celo7 I don't think anyone really wants to see that tho

eulB

12:07 AM

@ACuriousMind yeah but you had 2 before and after mod elections

normally you run a dude

if it's just chance then you should be like 50/50 male or female avatar

either a coincidence or planned i'd say

Obliv

@eulB I voted for ACM because I thought he was an orc posing as a female

back in his orc days

0celo7

I voted for ACM because he told me to

i barely even said anything, like 3 sentences, and it wasn't bad, could be seen as inappropriate for the circumstances which i said sorry for anyway.

anything else is him being dramatic for no reason.

@BernardoMeurer In principle it should be simple, but Prathyush's laptop has an RTL8723BE NIC that is allegedly supported but works very unreliably. Googling quickly finds thousands of posts complaining about it.

That's why we're looking for a USB wifi dongle to use instead.

Q: Decoherence of spin-entangled triplet-pair states in the solid state: local vs delocalized vibrations

The context: We are in the solid state. After a photon absortion by a system with a singlet ground state, the system undergoes the spin-conserving fission of one spin singlet exciton into two spin triplet excitons (for context, see The entangled triplet pair state in acene and heteroacene materia...

Long story short: Would the calculation of the loss of entanglement be necessarily related to delocalized vibrational modes that simultaneously involve the local environment of both triplets?

Suppose you have a masseless rod $\ell$ joining two masses $m_1, m_2$. Also, the through the middle of rod $O$ passes an axle, through which the rod can rotate freely. now i don't understand if you push $m_1$ in a line perpendicular to the rod, then why would $m_2$ move ? The only force which acts on $m_2$ is the tension, but the tension is directed towards $O$, but not perpendicular to it !

John Rennie

> The only force which acts on $m_2$ is the tension

That isn't the case

Since the rod is rigid it can transmit lateral forces as well

Alex K Chen

But well that isn't in my book :P

@JohnRennie So this is false ?

John Rennie

Well just consider a seesaw (teetertotter in the US)

Alex K Chen

yeah

John Rennie

You push down on one end and the other end goes up.

Isn't that the same as what you're describing?

Alex K Chen

10:04 AM

Yes, but why ? (I mean obviously it does, but I'm not understanding why)

My textbook (Halliday Krane) seems to completely chuck it though

John Rennie

Now imagine making the seesaw out of something very flimsy e.g. kitchen foil. This time if you press down on one end the foil just bends and the other end stays where it is.

Alex K Chen

Ah ! I got it

What's exerting the lateral force on $m_1$ ? The rod ? OK, so what's the reaction force ?

John Rennie

The force is transmitted to the object at the far end of the seesaw due to the rigidity of the beam connecting the two ends.

Alex K Chen

btw, what's the reaction force to friction ?

John Rennie

When you exert a downwards force on the end of the seesaw the pivot in the middle exerts an upwards force. The two forces create a couple that causes the beam to rotate about the pivot.

> what's the reaction force to friction

That's a rather vague question ...

Alex K Chen

10:08 AM

Why ? Suppose I have a block on a frictioned table surface, and the table and me are lying on a frictionless ice plate. Now I push the block on the table. What's the reaction force to friction ?

John Rennie

Suppose the block has a mass $m$ and the coefficient of friction with the table is $\mu$. And assume you are pushing with a force $F$ hard enough on the block slide.

Alex K Chen

yeah sure

John Rennie

You push with a force $F$ so there is an equal and opposite force $-F$ acting on you. This makes you accelerate away from the block/table.

The block experiences a force $F - \mu mg$ i.e. the force you exert less the frictional force. So the block accelerates away from you at a rate $(F - \mu mg)/m$

The block exerts a force $\mu mg$ on the table. So the table also accelerates away from you, but at a slower rate.

Hi! I have a question regarding measurement and observables in QM.

Observables are represented by Hermitian operators. First of all, it's a little strange that some measurable physical quantity is represented by a transformation. But this is not my doubt. I accept this definition.

The resulting quantum state to which a system collapses after a measurement is one of the eigenvectors of this Hermitian operator. The corresponding eigenvalue is the result of the measurement.

If I understood correctly, a measurement is performed by a transformation.

Q: Physics stack exchange alternatives

Where could one ask less highly sophisticated physics questions if not on stack exchange since my questions always seem to be formulated wrongly?

homework-and-exercises resource-recommendations education

@David Z @Emilio Pisanty & others: This was flagged for migration to Phys.meta then dupe close. Actually, it might be more useful to leave as a "bookmark" on the main site, since it is likely to be asked again. What do you think?

nbro

However, I am not fully understanding the relation and connection between the measurement and the observable (or the Hermitian operator that represents it).

ACuriousMind

@Qmechanic Migrating only to close as dupe is pointless, since closing as dupe automatically rejects the migration. Simply close with a link to the meta dupe in the custom close reason.

@nbro What do you mean by "a measurement is performed by a transformation"?

nbro

@ACuriousMind A measurement is performed by some operator, if I understood correctly. That is, in linear algebraic terms, you multiply by a matrix.

ACuriousMind

1:31 PM

No.

Qmechanic

@ACuriousMind : Right, but I was contemplating not migrating at all.

ACuriousMind

@nbro In the standard treatment, there is no operator associated to the measurement process itself, just the observable you measure. The measurement happens in an instant - before the measurement you have the initial state, after the measurement you have an eigenstate of the observable you measured. If you want to associate an operator to this "process", it's just the projector onto the corresponding eigenspace, but I don't see why one would do that here.

@Qmechanic Well, that's what I'm saying: Don't migrate, just close.

Qmechanic

@ACuriousMind : OK, I already closed it.

Emilio Pisanty

2:20 PM

@ACuriousMind @Qmechanic yeah, that was my flag but indeed I'm not sure how migration rejections work (migrate then close bumps it back, but is that also the case for close-as-dupe?)

Either way I'm not fussed about the outcome

If there's a way to push the mess to meta then it's marginally preferable but not by that much, either

ACuriousMind

@EmilioPisanty I'm pretty sure all closures reject the migration

I.e. the outcome on main is effectively the same as if we just directly closed it

Q: What is migration and how does it work?

Oooof

That's some intricate logic there

3:48 PM

guys, I've always found this confusing, but I wanted to check to be sure: if we have a conductor with some electric charge in a cavity, then there will be an outside field due to the charge in the cavity (though it won't depend on the shape or location of the cavity within the conductor), but if we have an external field, then this field won't penetrate the cavity of a conductor.

To me that's so strange, because I don't see the difference; why does it matter if we are dealing with an external field or a 'cavity field'? The situation seems symmetrical to me, but the results aren't

basically my question is; why is the cavity electrically isolated from the outside world, but the outside world isn't electrically isolated from the cavity?

0celo7

@ACuriousMind do you have experience modding TW3?

I'm trying to get a simple carrying capacity mod to work

ACuriousMind

@0celo7 Nope, I've never modded it

0celo7

it doesn't seem like it's a good idea to mod it too much

Sid

Can anyone explain what is resultant inertia force?

ACuriousMind

@ShaVuklia The situation is not symmetrical: For the field coming from the charge inside the cavity, there is no way its outside field could ever be cancelled by the charges in the conductor shifting: By Gauß' law, if there's a net charge inside then there's a field around it. But for an outside field, it's perfectly possible that the charges in the conductor shift such that they precisely cancel the outside field

0celo7

3:59 PM

@ACuriousMind modding games...what is this, 2016?

@ACuriousMind ahaha, got that sweet 10,000 carrying cap

Sha Vuklia

@ACuriousMind Oh right, of course. And we could also use Gauss' law to argue that the field must be zero in the case of an empty cavity, I think

(or maybe it's better to invoke an argument with $\oint E\cdot dl=0$)

@ACuriousMind Griffiths argues that if there were an electric field, then there would be a field line from a positive charge on the inner surface to a negative charge, and then if we complete a loop through this field line and a path through the 'meat' of the conductor, we would get a non-zero $\oint E\cdot dl$. While I think the argument is valid, I find the use of field lines a bit non-rigourous. Is it possible to adjust this argument to avoid using field lines?

this is the picture

4:26 PM

@0celo7 I didn't, Ryan lied.

Prathyush Poduval

@ShaVuklia The uniqueness theorem can be used here

Sha Vuklia

you mean that once we have found one configuration, we know that is the one?

Prathyush Poduval

yup

Sha Vuklia

but then I need to be convinced that this configuration exists in the first place?

Prathyush Poduval

take an equipotential volume, with the boundary same as the outer boundary of the metal

it is a valid solution, so it should be the only solution (I think this is there in griffiths)

Sha Vuklia

4:29 PM

a conductor already is an 'equipotential volume', so that's not really adding something new, right?

but Griffiths does mention something like this, where he considers a very large sphere. let me check if that answers my question

Prathyush Poduval

@ShaVuklia Now consider the entire volume of the conductor+ volume of the cavity

take that to be equipotential

Sha Vuklia

but the problem is I don't know yet if the cavity is equipotential, that's what I want to show

Prathyush Poduval

but the solution is determined only by the boundary condition

and there exist only one solution

Use the 2 above fact

@ShaVuklia I'll give you another proof

Sha Vuklia

what is the boundary condition here?

Prathyush Poduval

Equipotential at the surface of meta

Have you heard of the method of relaxation for solving laplace's equation?

Sha Vuklia

haha, yea I am rereading Griffiths, and I'm only at the end of chapter 2 (haven't done physics in a while)

Prathyush Poduval

It says that if $V$ satisfies laplace equation

Then the value of $V$ at some point $x$, is just the average value of $V$ at the points surrounding $x$

Abcd

@ACuriousMind I asked my teacher about it. He said that if you have counted a charge once, you can't count it again while finding net dipole. What do you have to say about it? @Sid Do you have any idea about it (sine you are studying EE I guess)?

Sha Vuklia

that sounds familiar

maybe I should get back to this later, after chapter 3

Prathyush Poduval

4:37 PM

So you can use this to argue that $V$ constant throughout satisfies laplace equation

Sha Vuklia

right, chapter 3 deals with the uniqueness theorem. I will read back what you wrote after I've read that part. I guess it will become clear then

Prathyush Poduval

@ShaVuklia Ah, Ex 3.1 of griffith is the one which proves that problem

Sha Vuklia

o really, let me check it

Prathyush Poduval

It's been a long time since I did classical EM

Sha Vuklia

same:p anyhow, thanks for your help, I hope it will get clearer soon

Prathyush Poduval

Yeah it should, EM takes practice and time to understand (but it gets easier once you get to relativistic EM)

It becomes much more intuitive and elegant

Sha Vuklia

yea I have faith in that!:p

Sid

@Abcd We don't study electrostatics in EE. In any case, could you elaborate on the problem?

@Sid EE = electrical engineering? or are you in electronic engineering?

@Abcd I don't have much to say about it except that that's not an argument, he just asserted again that that's the correct way to do it but didn't explain why.

Sid

@Abcd Electrostatics is not very useful in everyday life

ACuriousMind

But all this stuff with dipoles and such was never my forte, so he may well be right - it's still a bad explanation, though

Sid

@Abcd follow your classmates approach. I always used that. Since, I never cared about 2q breaking into q and q thingy, I don't know why they do that

Or if you like, follow your teacher's method if both give the correct answer.

Abcd

@Sid Huh?

@Sid I can't follow my classmates method when charge density around a ring is given by $\lambda = \lambda_o \cos \theta$

Now again the same problem arises

for each +q there are two -qs of same magnitude

We did this problem in class too, and we just considered one for each

Maybe its a matter of definition? If anyone has any textbook/ book comments/ quotes on this please let me know.

Sid

maybe JR or some other electrostatics expert can help you on that

well that's a contracted form of "intelligence quotient"

0celo7

I know what the acronym means

There's no reason to change the terminology, everyone knows what it means

Balarka Sen

@0celo7 Not only do I think people are triggered by it, I think most people just flat out misinterpret it, so I disagree

0celo7

I resist attempts at relabeling things

Balarka Sen

I advocate changing bad labels

Sir Cumference

Feynman had an IQ of 125, but attained an unprecendented perfect score on the graduate school entrance exams to Princeton in physics

I wouldn't call the cohomology ring of a topological space as it's homotopy type :p

Sir Cumference

He derived some calculus concepts before entering college. Pretty sure IQ doesn't mean anything

0celo7

Feynman is the definition of cherry picked data

Balarka Sen

@SirCumference That's... a flawed conclusion.

From a data set of size 1 :p

0celo7

trump's IQ is 160

Sir Cumference

@BalarkaSen At the very least, the guy didn't let that stop him

IQ on the average shouldn't let anyone stop from doing anything much, no

@SirCumference I looked around, and it seems the standard deviation of a standard IQ test is about 15 scales plus or minus from the mean.

Statistically, at least.

@CaptainBohemian yes I was born in Cameroon, and spent my formative year (primary and secondary school ) there, but I am also an American citizen.

Just learned that Jeff bezos makes $36,000 a minute. Cool!!!

Scratch that he might actually make about 3 times that a minute right this moment, according to reports. So close to $100,000 a minute

huh

cool

So he makes more in one minute than the average american( more like an american close to upper middle class) makes in a year. sexy

Captain Bohemian

@Cows Then you are exempted from taking the English test automatically if you want to go outside Cameroon to study or work?

@CaptainBohemian well, not quite. For some reason, they tried to get me to take English as a Second language, but I fought back and ended up taking the standard college English courses. I took the composition class, the literature class and critical thinking.

@CaptainBohemian I noticed from your profile that you have an interest in English language. Are you studying some kind of linguistics?

@CaptainBohemian Did you grow up out of the US too?

Captain Bohemian

@Cows no. It's strange my country never teaches us linhuistics, but recently I started to find linguistics seems to be an interesting subject from the answers people give in English Language Usage, so may learn it gradually.

@Cows I actually didn't know English at all before entering middle school. Our curricula teaches us English starting from middle school.

@Cows and throughout middle and high school, our English courses only focused on reading and writing, so even people who can't speak nor listen English can graduate from high school and be admitted to univesity.

@Cows I have met people from math department who can't understand much spoken English in my university English class, which is the first rank students of English being admitted to our science college.
