You don't have to import them -- it can be a link to their SE profile if they haven't created it, no? I would argue by linking to an artificial/unclaimed account on your own site, you're breaking the license by not linking to the real creator's account... but it's been awhile since I've looked at it
2
The license plain-text says something under attribution "... but not in any way that suggests the licensor endorses you or your use." I would think making it look like they have an account on your site when they don't implies an endorsement

@tpg2114 Especially if the gravatar and name is also imported like in that example right?

That's why the profile makes it clear that it's an artificial account and links back to the SE account. It's not practical technically to have content without an attached account, so this is the best compromise we've found. I have checked that it's legal :)
@NikeDattani Gravatars are never imported.
 
tpg2114

Well -- I'll leave it to y'all to sort out, it is your site after all. But "it's legal to do this" isn't always a way to placate people who are angry you've done it :)

@tpg2114 less "it's legal to do this", and more "it's not legal not to do this in some form"
 
tpg2114
tpg2114
You could just as easily link to their SE profile instead -- that would be legal too. But it sounds like that's more technically challenging and you don't want to do it, which is a different thing than "this is the only way."

It might also be worth it to mention, that they assert that they are only bound to UK laws, and if they are sued it has to be in London, UK (this might not mean much unfortunately, as the Canadian Supreme Court just ruled that Uber can be sued in Canada... doesn't have to be San Francisco, in a class action law suit for Uber drivers to be given "minimum wage" and benefits like dental, etc.

It's hard to say you're bound to only one nations' laws when you operate an international site -- many courts will assert jurisdiction over something when it can be demonstrated a large portion of their business happens in that jurisdiction

I don't have a horse in the race either but I would hope that whatever information is being shared about fulfilling copyright is at least correct. It pains me to discover otherwise. (in cases where the information turns out to be incorrect, I mean; I'm not saying this is one of them)

The minimum standard is whether what we're doing is legal. Beyond that, we have to strike a balance between what the "best" solution might be, and what's possible technically - sure, it's possible to link directly to an SE account, in the same manner as it's possible to remove a wasp's nest without protective equipment... that doesn't mean it's the best balance.
 
Nike Dattani
Nike Dattani
@ArtOfCode "it's not legal not to do this in some form" , it is not legal for you to import the content without the attribution, but you could always just not import the content. So the angry people will not just be angry, but they won't buy the argument that you were compelled by law to import their usernames (since you weren't compelled by law to import their content)
 
ArtOfCode
ArtOfCode
We also have to consider that when people click on a username, they're expecting a profile as part of the same site - taking them somewhere else is cognitive dissonance, so you'd have to indicate it somehow, which is also not necessarily trivial. It's a balance between lots of things which often aren't immediately obvious.

@ArtOfCode May I ask where the funding for the network is coming from? It's just your personal savings?

tl;dr: no, there's very little expenditure at the moment and it's mostly covered by various private contributions
 
David Z
David Z
@ArtOfCode I gotta imagine there are various ways to work around that. Like, you could always make imported usernames non-clickable, or make it so that clicking on them takes you to a page saying "This account doesn't exist, but it corresponds to content contributed by [account on SE]" or something to that effect. (And I believe it's not even clear at the moment whether SE's attribution requirements are legal within the scope of the CC license... or was that resolved?)

@DavidZ There are ways to work around it, sure, but it's not necessarily trivial.
SE's additional requirements aren't technically legal, and we don't technically have to comply - all we have to do is have the username... but we're not in the business of poking bears.

Last night dream:
Some Newton problem of solving the velocity of a moving body, but the maths used is really weird
Basically:
There is only one equation, which is $$(\nabla_u - \nabla_v)V \int G \delta x$$
where $G$ is some extremely complicated thing that depends on velocity
Solving this equation actually carry out the process shown in the diagram above:
1. There is an optimisation of a functional
2. followed by fixing a tensorial parameter that defines the value of each point of said functional
3. and then fixing some parametrisation of said functional by the step $\delta x$ so it becomes a numerical form
Translating all that dream logic into more legible mainstream concepts, I think what it is trying to do is the following:
1. You have some functional. That get optimised
2. After that, there is still a tensor valued parameter $P$ that defines the tensor function $T (\mathcal{C},P)$ that will be fixed by the equation (I forgot what's on the RHS which is why I have not wrote "=")
3. After both of that is fixed, it then does the parametrisation $T (\mathcal{C}(\delta x),P)$ to finally complete the solving of the equation. Somewhere in there, the velocity is contained in $T$
typo: $\mathcal{C}$ is the functional

Interestingly, this is quite similar to this
an old approach to modelling visoelectricity
Viscoelasticity
Viscoelasticity is the property of materials that exhibit both viscous and elastic characteristics when undergoing deformation. Viscous materials, like water, resist shear flow and strain linearly with time when a stress is applied. Elastic materials strain when stretched and immediately return to their original state once the stress is removed. Viscoelastic materials have elements of both of these properties and, as such, exhibit time-dependent strain. Whereas elasticity is usually the result of bond stretching along crystallographic planes in an ordered solid, viscosity is the result of the...

@vzn Also figured out something on simulation hypothesis
At least as far as turing machine concerned as a simulation machine, the biggest difference between reality and simulation is that in a simulation, all things are "discretised"
That is in every frame, there is always something that is clearly A or clearly B
that even holds if you have quantum computers (which still fall within the domain of turing machines) because a pure and mixed state is in a sense, "well defined"
Probability distributions and fuzzy logic thus is a low level way to approximate a "mush" but they are not actually vague things
likewise, infinity in a simulation is also "discritised" as you do not ever have a situation where there are multiple possible interpretation of what infinite object it is

Mad Spaces

Could someone test my understanding of this matter. I am not sure if i understood it Right.

When we put some material in a magnetic field. then it will become magnetized.
this happens because in the magnetic fields the charges seperate and become Dipols.
thus small Electric fields raise up.
At this Point i think of it as a conducting wire.
In a conducting wire results a magnetic field due to the elctric field.
Thats why magnezited Dipols create Electric fields which in their turn create magnetic Fields.

Yeah true, it just seems like I have been seeing a lot more lately.
In HW questions and probably in the more recent "Big List" question that was recently asked about on meta
 
ACuriousMind
ACuriousMind
And I can certainly see arguments for that - it depends on how general you think about our mission and what you think the rules about on-topicness are for.
If you think we're supposed to be a repository of physics knowledge and the purpose of the rules is just to keep uninteresting or non-physical stuff out, then there's little argument for being a stickler about rules like "too broad" questions
 
BioPhysicist
BioPhysicist
Yeah I was just thinking the same exact thing earlier today actually haha
 
ACuriousMind
ACuriousMind
But if you think we want to curate high-quality questions and answers with a specific focus and the rules are mainly about disincentivizing future questions of a particular kind, then there's much more motivation to apply it even in cases where you might personally think the answers would still be good and interesting

About how some people want PSE to be a site that is "anything physics related goes"
I think I fall into the latter camp only because it seems like that is what the site policies are going for

I think many people start out in the first camp and end up in the 2nd
It's also kind of the way communities evolve. When it's a blank sheet, it's nice to have few rules and let things grow organically -- if it's overly-prescriptive, people get discouraged or the rules may be misguided for what is actually needed or good

I believe the latter is much more in line with the "original spirit" of SE principles like "pearls not sand", but of course you're not required to subscribe to any of these to participate here

BioPhysicist
But if sand keeps getting reopened then should we reevaluate things?
 
ACuriousMind

Alas, stuff like the semi-recent rebalancing of question votes to +10 instead of +5 suggests to me these principles are also no longer at the core of what SE wants for its network
 
tpg2114
tpg2114
We should always be evaluating/reevaluating things, otherwise we grow stale. Isn't there some saying about if you aren't moving forward then you are moving backward?
Of course, reevaluating doesn't mean changing per se.

BioPhysicist
"If you aren't moving forward then there are still an infinite number of other directions you could be moving in"
that one? :P
 
tpg2114
tpg2114
Heh -- and one of the main things I've learned from my colleagues, there's an infinite number of possible directions to go and we will never do them all. Or many of them. Or several of them. So we have to pick the ones that have the best impact on the most people
Which, to paraphrase, is "pearls not sand" -- there are plenty of places to ask random questions and get discussion from random internet people. And there are plenty of places to ask homework questions and be given an answer. So there's not a reason for us to fill that role too :)
 
BioPhysicist
BioPhysicist
5:12 PM
What do you do when more experienced users are still not aware of "pearls not sand", or when many users say, "nah, I want sand", and then reopen sand anyway?
 
tpg2114
tpg2114
For the latter -- if you aren't experienced enough to know pearls from sand, then we need to keep explaining what makes them different and why we only want the pearls. I suspect many of the people who say they want homework questions here think either A) homework questions are really good, useful questions or B) want to help people who are stuck on homework.
 
BioPhysicist
BioPhysicist
Yeah, and I totally understanding wanting to help people. Which is why I also tutor haha
 
tpg2114
tpg2114
A is just not having enough experience to know what makes good questions good, and B is about thinking our site has to do more than it currently does -- and the answer to both is to have conversations with them about it
Different conversations, sure. But if we can do X + Y, that also means we could do more/better X -- and if give that choice, does it still make sense to pick X + Y?
Not saying there's right or wrong answers, or that our current scope/policies are rock-solid 100% perfect. But it makes sense given where we are that we continue to focus on deeper/better in scope than wider scope

@MadSpaces There is no easy answer to that question. The best you can say is because spacetime is tied up by the constancy of the speed of light, hence electric and magnetic fields are related to each other by motion

And that's okay too -- "Look at why we decided what we decided, and then explain how the situation has changed to warrant revisiting it. Also make new points that support the change, because if the only change is 'I want it now too', then that's not enough"
If somebody wants to come up with a new homework policy that addresses the current weaknesses while not re-introducing things people objected to or pointed out before, I'd be all about it. I hate our homework policy -- but, it was the best compromise we could come up with that tracked the best course through everybody's wishes
It does get annoying when somebody flips out that we close something and they don't know or care to learn the reasons why... that does wear me down
On the plus side, I get to keep up my "Darn kids, get off my lawn!" routine :)
 
BioPhysicist
BioPhysicist
What would you prefer the homework policy to be?
 
tpg2114
tpg2114
I don't have a solution for it actually. I think our current one is too complicated for people who don't know what they don't know -- we tell them to show their work but tell them we won't check their work. We tell them it needs to be conceptual, but for the US physics education, memorized formulas are the concepts
If I could, I'd say no homework at all. But then how we do know if a good conceptual question is homework or not, so that's not really a helpful rule either
I suspect our policy, for all its flaws, is really the only neutrally-stable critical point in the homework state space. But it only stays there if we keep poking it things back in place
It has things we can act on as well as identifiers to know when to act, while making sure the floodgates don't open and it becomes a free for all. I don't know what else we could do that is actionable, identifiable, and has quality controls baked into it
 
BioPhysicist

I have never been a fan of just telling users "show your work", since that isn't sufficient to make the question on-topic given the current policies

So... madspace's question caused me to become curious and revisiting the moving charge problem in relativity
It's interesting how the extent the electric and magnetic field get squished, is in agreement to the magnetic forces that is felt by any test charges in any points of the electric field as seen from the lab frame
so the extent of squishing of the electric field, is due to the magnetic field hence the magnetic force that is produced
this is also consistent with the interpretation that magnetic fields are really electric fields seen in a moving frame
but it is not as directly related since the magnetic field is always orthogonal to the electric field, it does not directly contributed to the change in the shape of the electric field
rather, it is the resulting magnetic force that is produced, that end up compressing the charges together along the direction of motion, leading to the outcome that the electric field is squished
Of course, the usual interpretation that spacetime get length contracted and time dilated is a better one because it is less messy than to try to reason how the apparent fields change the position of every test charge in the region
but then, magnetic fields from permanent magnets is due to spin, and spin stays the same regardless of the frame of reference, so I am missing something here
where is the electric field that accompanies the magnetic field of a permanent magnet?
like for example, neutrinos have magnetic moment, but no charge
so a moving neutrino will have a transformed magnetic moment in the direction of motion as expected by special relativity, but now there is no electric field associate with that because it has no charge
(I picked neutrinos because to avoid the obvious explanation of orbital angular momentum of electrons in the molecules of a magnet, thus getting rid of any electric sources completely)
