by the Alexandrov-Penrose theorem the thing can even be a ball, topologically

so no holes

something has to go wrong if a spacelike geodesic leaves

peterh

@ACuriousMind It is strong argument. I am thinking on it. I think, the optimal balance would require a statistical processing of the site data, extended with a little bit AI. Other global companies, particularly the Google, are doing this. I am nearly sure, that the SE doesn't. And we mortals don't have access to the most important part, to the voting data.

Slereah

Do tell

0ßelö7

I need about 5 false alerts

I do have an idea though

peterh

@ACuriousMind The most important factor affecting my opinion is that I can feel very well the disappointment, what a question closure generates. But I can't feel very well the disappointment, what the bad questions generate in the experts/answerers. On other sites, where also I am an expert, I simply vote down/close the bad posts and forget them. They would only annoy me if they would be far more. But if I see a good, or at least acceptable question with close votes, that makes me disappointed.

If $p,q\in D$ where $D$ is the diamond, consider a geodesic $\gamma$ connecting them

This is the unique geodesic from the CNN

Suppose $\gamma$ leaves $D$. Then it must intersect $\partial D$ in two places. I think this violates uniqueness

maybe not

this seems like an impossible situation @Slereah

Slereah

00:12

what would be the other geodesic connecting the two in this case?

0ßelö7

idk, from that picture it seems pretty darn obvious that one should be able to connect them within the diamond

peterh

@ACuriousMind I am inclusionist. As internet communities mature, typically their deletionist line strengthens. As far I know, the PSE got the deletionist majority roughly in 2012-2013. I think, you see a relative pure and clean site, what is the current PSE. I see also a site, what is larger as the MathSE and educates the schoolkids of the future on the whole Earth - and which site never existed. But it could have existed.

Slereah

Well yeah but if we only had to rely on obvious we wouldn't need a proof

0ßelö7

@Slereah Are these small causal diamonds globally hyperbolic?

Slereah

Hm

By "small diamond", do you mean the image of an actual diamond from the tangent plane?

Because the timelike cylinder is causally convex

0ßelö7

00:18

idk what exactly I mean. Probably $I^+\cap I^-$ for two very close points

Slereah

$I^+$ and $I^-$ is the whole spacetime for totally vicious spacetimes

for any point

Although yeah I guess it would be?

I'm not sure tho

0ßelö7

the spacetime is strongly causal

Slereah

I mean

There's always a globally hyperbolic neighbourhood around any point

So just do a causal diamond in that neighbourhood

You'll always get one

0ßelö7

look

I don't think there can be a piece of the boundary over there

Slereah

what's that neighbourhood?

0ßelö7

00:26

although this is possible lol

@Slereah the image of the diamond under normal cordinates

Slereah

yeah that's the issue

gotta prove that it is indeed convex

0ßelö7

@Slereah For what it's worth, Sanchez avoids using this in his proof of the Alexandrov topology theorem

Slereah

Yeah isn't there just one book that uses that theorem?

Secret

Some random time travel model thought: Instead of having each spacetime point being some fixed value, perhaps we can instead express them in terms of functions of every possible worldline that lead to it.

Therefore, each spacetime point will become path dependent, and observers will see different energy momentum densities depending on how they reach it from some initial point

0ßelö7

@Slereah let's see if any of the BEE crowd are alive

Secret

Under this framework, the currently open question will then be whether the resulting spacetime diagrams will be consistent at every point for all observers and all possible worldlines

0ßelö7

If the time travel is type 1, then this path dependent spacetime reduces to the CTC case where every spacetime point is path independent

Q: What are quantum fields mathematically?

I'm confused as to how quantum fields are defined mathematically, and I've seen from questions on this site and Wikipedia articles that classical fields are just functions that output a field value for a given point in space input. Is this the same for quantum fields? Are quantum fields too just...

Thinking...

Emilio Pisanty

10:09

@JohnRennie wait, what? What's an antipositron and how is it not an electron?

(I know, probably explained in your links, I'm a slow reader)

John Rennie

@EmilioPisanty An antipositron is what you get if you flip the chirality of an electron

ACuriousMind

@EmilioPisanty The link discusses a hypothetical world of massless leptons in which the chiral parts of the electron decouple. It then calls the left-handed part "electron" and the right-handed part "anti-positron". In reality, leptons have mass and the "electron" and "anti-positron" in this terminology mix to yield our ordinary electron.

This terminology is useful to discuss the weak interaction because it's chiral and only couples to the "electron", not the ordinary electron

It would be even more useful however if it didn't overload existing terminology :P

I called the "electron" and the "anti-positron" electron-1 and electron-2 in this answer of mine

@MathematicsAminPhysics If you want to inform people that some sort of event is going on in your personal chatroom, that's fine (once), as long as you are very clear that this is your personal project and noone else is involved with it.

In particular, calling it a "course" and posting in that format already has misled users here once that this was somehow an event endorsed by this room and its owners, which I won't let happen again.

@ACuriousMind Ok. Can I post in in this format?: "The following event is to be held; it has nothing to do with this room"

ACuriousMind

@MathematicsAminPhysics I would much prefer if you'd use "I want to hold event X in room Y on date Z, come by if you like" instead of the passive voice which strongly suggests there's some larger organization behind it. (If there is a larger group of people behind this I'd be happy to know, but so far the evidence suggests it is just you)

@ACuriousMind is the depiction of the physical electron in that article wrong? Shouldn't it show a combination of left and right chiralities?

Oh no, hang on ...

ACuriousMind

@JohnRennie That image is weird and probably shouldn't have an arrow at all on the l.h.s. and a red arrow on the mustachioed particle

user84215

@EmilioPisanty First I posted that event in a correct form. Then one of the moderators wanted me to change its format. You can see its correct form in ♦ Trash.

John Rennie

@ACuriousMind Unless the arrows are showing helicity not chirality

Sid

My Afghan friend clearly doesn't seem to like this train journey

ACuriousMind

11:11

@JohnRennie Oh, right, the arrows are helicity

John Rennie

I think that's what confused me. The author is being casual about distinguishing between helicity and chirality

ACuriousMind

It's terrible to say "left-handed" for helicity btw because "chiral" also means "handed" - chirality means handedness.

John Rennie

It also isn't clear which of his particles are massless, in which case the helicity and chirality are the same of course.

ACuriousMind

@JohnRennie The author says it shortly before that - the arrow is helicity, the mustache is chirality

John Rennie

Aaaaaaaaaaaaaaaah. Bing!

ACuriousMind

11:15

Which is confusing because that's not exactly how it worked before that, but I guess the author managed to confuse themselves multiple times during writing that article as evidenced by all the edits ;)

John Rennie

I managed to thoroughly confuse myself reading the article, but to be fair it (and your help :-) have illuminated an area of physics that was previously totally mysterious to me.

ACuriousMind

The chirality/helicity business is pretty confusing and most texts are abysmal at actually explaining it, so yeah, the article is pretty good even if it could be a bit streamlined to reduce the change of confusion

Emilio Pisanty

11:33

@MathematicsAminPhysics none of the forms you've posted are "correct", and the criticism of the previous versions is also on the dot

It seems that you're not quite fully brushed up on what does and does not constitute misleading advertising, but if you want to advertise in this room then you will be held to our usual standards, which are rather higher than what you've written thus far.

Felix.C

12:01

Hi Rennie thank you very much for your offer to explain the uncertainty principle!!!
Eventually I figured out, that quantum mechanics say...and I take them for granted...that momentum and location are just a change of basis using the Fourier transformation...This makes the uncertainty principle rather trivial imo

ACuriousMind

12:27

@Felix.C Although I would agree that the uncertainty principle is much less mysterious than it is usually made out to be, I'd caution against seeing it as an instance of the Fourier uncertainty. Rather, the implication goes the other way around: The Fourier uncertainty is a special case of the much more general quantum mechanical principle, see e.g. this answer of mine

It's an important enough metric to get a name

Secret

If it is new, I will prefer naming it in a descriptive manner such that it highlights the most characteristic property that is unique to this metric

For example, how does it differ from the usual wormhole solutions

NB. From naively looking at this metric, it seems this spacetime has some kind of "cone like shape" for its radial component

this is because the $l$ dependence of the angular components

user129412

13:52

Based on a discussion I was having yesterday, does the following make sense? I have a particle in an infinite box (s.t. E_n = n^2/L^2), and I say that the box is filled up to some E = E_f. Lets say that for L = 10, there are N = 5 states for which E_n < E_f, so they are occupied. If I now increase L (and keep E_f fixed), how will N scale with L? Linearly or quadratically?

Just trying it on paper shows me that it is linearly, but somehow it isn't intuitive to me that the ^2 of the n cancels with that of the L. I'd still think the energy separation changes quadratically. But I guess, by writing it now, it makes sense that the factor from the state number itself also scales quadratically so that it does indeed cancel

@ACuriousMind I think any big text can be summarized into any small one. Of course it will result information loss, but no OP can think seriously that he will get a 200 page long answer for a single-sentence question.

Semiclassical

@peterh "How does one prove Fermat's last theorem in full detail?"

ACuriousMind

@peterh I don't think OP expects a 200 page long answer. I think OP simply doesn't realize that what they are asking for is such a long answer, because they seriously underestimate the amount of stuff that goes into the theoretical machinery of the Standard Model.

Semiclassical

That sort of question would sorta demand a long answer. (Whether they'd receive it, of course, is a different matter.)

peterh

14:43

@Semiclassical I think, the pretty answer for that is a summary, showing how the proof works. As far I know, it has uses some tricky features of the elliptic functions to prove a conjecture, which follows also the Fermat-theorem. It is not a request to copy-paste the whole theorem, it is a request to understand, how the proof works.

@ACuriousMind Thus, they don't get a complete answer, only a summary of a possible complete answer. As I tried to explain it on the Meta SE, I got terrible reactions, but only very few arguments.

@peterh There is no "summary" of QFT or the Standard Model that avoids the sort of mathematics OP wishes to avoid. The answer OP wants simply doesn't exist, and the only way to answer their question would be to explain all the mathematics to them from the ground up.

Balarka Sen

@JohnRennie Can I ask you a physico-chemical question?

John Rennie

You can ask ...

Balarka Sen

so we know that the rate constant of a chemical reaction satisfies $k \propto \exp(-E_a/RT)$ where $E_a$ is the activation energy required for bootstarting the reaction and everything's happening at Kelvin temperature $K$.

That's the Arrhenius equation

John Rennie

That's more of a phenomenological rule than a fundamental one, but yes it generally works.

Balarka Sen

Right

So I was wondering if there's an electrochemical explanation of this, where we have the similar "expression" (Nernst equation) $Q \propto \exp(nFE^0/RT)$ flying around for an electrochemical reaction with reduction potential 0, $Q$ being the reaction quotient.

Or if this really is a superficial similarity

Semiclassical

15:18

I suspect the common thread is "statistical mechanics"

Balarka Sen

I guess we could potentially (no pun intended) think about $E^0$ as the activation energy for an electrochemical reaction

@Semiclassical hm

John Rennie

Um, ah, no I don't think so.

Isn't is related to the fact that the EMF is the log of the free energy change? Or is it the other way round ...

I'd have to dig out my physical chemistry books to refresh my memory.

But I don't think it's related to having an activation energy.

Balarka Sen

Hrm

I never really understood the standard electrode potential to be honest.

Semiclassical

the relevant bit of stat mech is that, if you've got a canonical distribution, then the probability of a state n is given by Pn ~ e^(Sn/k)

that's just boltzmann's entropy formula, really

and then Sn/k = (Fn-En)/(kT)

where Fn, En are the helmholtz free energy and the total energy of that state

Balarka Sen

hmm!

John Rennie

15:30

Let me dig out my copy of Moore's Physical Chemistry.

Balarka Sen

Thanks

John Rennie

Page 520 (out of 969). Goodness it's a tome.

OK $$\Delta G = RT \ln Q $$

Balarka Sen

Right.

John Rennie

That's just regular thermodynamics not electrochemistry

Balarka Sen

I agree

I think $\Delta G$ turns out to be proportional to $-(E - E^0)$ in electrochemical reactions.

John Rennie

15:33

And when you transport a charge $z$ across an EMF $E$ the free energy change is just $$\Delta G = zFE $$ where $F$ is some constant or other.

Balarka Sen

Ah, yes, true

John Rennie

So you end up with $E \propto \ln Q$.

Hence the exponential form

So, nothing to do with an energy barrier. Sorry :-(

Balarka Sen

Aw

Semiclassical

:/

John Rennie

But if nothing else you've reminded me how tedious it was to study electrochemistry and how pleased I was to give it up :-)

Semiclassical

15:37

I'm not sure why the EMF itself wouldn't count as a barrier.

Balarka Sen

@Semiclassical That's what I was trying to get at

Semiclassical

You have to do a certain amount of work as you move the particle across.

it's a chemical potential, really

see for instance the discussion here: en.wikipedia.org/wiki/…

Balarka Sen

It seems the correct analogy to the Nernst equation would be the Eyring equation

John Rennie

But the Nernst equation is a statement of equilibrium properties. There is nothing in it related to kinetics.

Semiclassical

hrm

even so, I'd classify this under the common rubric of stat-mech /thermodynamics stuff

Balarka Sen

15:42

@JohnRennie It does give information about the equillibrium constant, doesn't it? Which is possibly where the kinetics is happening (K is a ratio of the rate constants of the forward/backward reactions)?

I mean I am not saying anything rigorous, merely asking if what I am saying can be made rigorous in some formalism

It'd be disappointing if the similarity in the formulas turns out to be a coincidence...

John Rennie

The equilibrium constant is related to the free energy by a Boltzmann distribution type thingy.

Balarka Sen

Right.

John Rennie

When you have two systems with energies separated by $\Delta G$ their relative populations will be given by $e^{\Delta G/RT}$.

Semiclassical

This is in the grand canonical ensemble?

John Rennie

The Arrhenius equation originates prom the fact the the proportion of reactants with enough energy to cross the barrier is also a Boltzmann distribution $e^{-E_a/RT}$.

@Semiclassical This is frenzied arm waving :-)

Semiclassical

15:46

lol

i'm more wondering if that's the distinction here

John Rennie

(because I can't remember the details :-)

Semiclassical

if the two scenarios involve similar reasoning but different kinds of ensembles

Balarka Sen

@JohnRennie Ah, hm

John Rennie

I love the way you say hmm when you're thinking he's talking bollocks but I'm not sure exactly how :-)

4

Semiclassical

hmmmmmmmmm

John Rennie

15:48

:-)

Semiclassical

my feeling is that it should, for both of them, boil down to energy barriers

Balarka Sen

@JohnRennie ahahah

Semiclassical

just electrochemical potential vs. the energy of an excited intermediate state

so the difference between "provide energy to move it from one place to another" vs. "provide energy to get it to an excited intermediate"

it's like the distinction between, say, Zeeman energy and electric potential energy. Both are forms of potential energy, just with different mechanisms.

and whether you count these as being 'the same thing' will depend on what you're interested in

@JohnRennie reverted somehow

it keeps getting upset by the .log files in the TeX and it's not letting me ignore the changes

On GitHub you can drill down to see an individual file and there is a history option somewhere that lists all previous versions.

I can't sync the repositories

ohh, I bet github clashes with teamviewer for some retarded reason

@0celo7 hmm. You can still redownload the rolled back repository into a new location and copy over anything you've worked on.

0celo7

@JohnRennie The good copy is on my desktop. I used teamviewer to save it

I should just wipe GitHub and put the good copy on it

How do I set it to ignore every file except for the .tex? It keeps getting messed up by the .log

And when I click ignore it does nothing

John Rennie

In that case create a new empty repository on GitHub and download it to your PC. Then copy in all the files you want in the repository and git add them then commit the change. Then sync back to GitHub.

New files, e.g. .log files, aren't added to the repository until you git add them. If you want to keep the logs you need to add them. If not just delete them.

Better still configure your TeX compiler to write log files to some other directory.

0celo7

I don't know what git add means

John Rennie

@0celo7 different graphical environments work in different ways, so I'm not sure what you need to do in yours. But when you add a file to the directory containing your repository it isn't automatically added. You have to explicitly add it.

On the command line you use the command git add <filename> but with the GUI presumably there is some graphical way to do it.
