8:00 AM

indeed, I hope he is alright even though a brief search on the novels no longer talked about him

user228700

@Secret Strangely, that does remind me too about the veil! That pool is a pensieve before it turns into some form of lava. I thought that was beautiful :-)

@Kaumudi received. Tell your friend the number of nice people in the world far outweighs the number of nasty ones. It's just that you notice the nasty ones more.

user228700

@Secret I did some googling and found that he does survive. Ezra miller, who plays Credence is shooting for the next movie and that's evidence enough :-)

user228700

@JohnRennie :-) Thank you. Will do.

@BernardMeurer or south america

8:05 AM

@G.Bergeron I'm not sure what your point is. The expression you mention is not the one I asked about.

Is it it worth it to add an answer there:

Q: Do the results of statistical mechanics depend upon the choice of macrostates?

Consider a magnet with temperature $T$. We can observe its net magnetization $M$, so we say that a value of $M$ specifies a macrostate. Statistical mechanics tells us which macrostate the magnet is in. To do this, we compute the free energy $F(M)$ and minimize it. The free energy is defined by $$...

statistical-mechanics entropy

Initially, I thought the execution goes like this:
1. Goldstein get strapped on the seat
2. Memory get extracted and sent into the death potion. The potion act like a pensive and use happy memories to lure her in
3. The seat lowers through the death potion, and then Goldstein dies with the "chaaarrr" like breath sound similar to Sirius Black, as she flaot and disspaite below th potion as if the potion is the boundary of the veil.
One reason it reminds of the veil is how Goldstein and Scamander's extreme crying fear about it as if they are going to be drowned, which means it is a very very c…

In fact, that emotion is so strong (also with those obscurial scenes) that had the identity of that death potion was not documented, the emotion do cause me to have an urge to just want the whole world to turn gray, time stopped, people become apathic, and then thw world end itself as balckness swallows it in from within

I feel like something is missing from the existing answers, but there are so many of them. Do you guys feel like at some point the answers just drown each other?

The destruction scenes involving the obscurus (not the scenes involving Credence in human form), is pretty cool to me through cause I never saw a formless darkness ever being depicted with such a solid form (there are a few scenes where the obscurus move like a snake) that it does really reminds of a beast roaming around

you're a fan of harry potter?

8:18 AM

Morbidly speaking, I would rather watch someone being burned alive than died veil fashion. This is because at any stage of execution like that except the veil, it is reversible once you save the guy from the execution

I am kinda a fan as I have wacthed all 7 harry potter movies

Oh, @DavidZ did you see my answer?

@Secret meh... you could have just had time to spend

No I actually like those movies, I basically grew up with them

@Secret I don't know, I think I would much prefer see someone getting thrown through a veil!

@Secret Yeah... I realized recently that I never finished that series be it in books or in films

I don't know the ending!

@Secret what didn't ul like about the executio

I don't like anything that reminds me of what I called the emotion of nihilation: Something that cannot be reversed under any means, looks falsely peaceful and very depressing and only reminds of staring into an infinite nothingness. It reminds me back in the high school days when I am being bullied, the bullies always win and you can do nothing about it.

8:23 AM

Any death ends up like that... I'd just skip the pain

(although the truth is, for my case I m lucky that my teachers are on my side, thus the bullies are taken cared of, but for some reason this emotion stayed)

@Secret Well you could have done many thing with bullying ... it is just hard to be resourceful like that as a kid

@Secret so you don't like that the execution was slow?

I got a bit of bullying younger

@G.Bergeron one might assume so since I replied to it ;-) I'm just not sure how your answer is supposed to help me.

8:25 AM

But I mainly regret not seeing it for what it was at the time

@G.Bergeron if you didn't realize you were being bullied then why does it even matter?

It has nothing to do with whether the execuation is slow or fast. It has to do with if you intervene it, you can still save that soul. The veil is unaturally peaceful considering how Sirius is being pushed in and died as if by some unknown force, and cannot be reversed at any stage of the dying process

@DavidZ Did not see, but I showed what factors where of surplus

it strongly reminds that emotion of nothing

@Mew More like I don't see it as a big deal now

8:26 AM

@G.Bergeron again, I don't understand what you mean

i c

@Secret I don't get it, would much rather be shot in the head or veiled than being burn at the stake or fired alive, I mean really?

@DavidZ Well I mean that I should not have given a crap at the time

@G.Bergeron If the person dies, then yes I will agree that being shot, veil is much better than being burned alive. The point is if the person is not meant to die, we can reverse it for the gun shot and burning case, butnot the veil

@DavidZ Not that it was intense or anything, really run-of-the-mill high school level

@G.Bergeron wait, what? Now I really have no idea what you're talking about

8:29 AM

@Secret What? How will you revive a pulverized brain?

@Secret why cant the veil be reversed?

@DavidZ Sorry conversation overlap

@Mew second law? :-)

Not all gun shots are 100% fatal, but the veil is 100% fatal because the person just dies as if passing through a one way passageway

@G.Bergeron ah, I see

8:30 AM

@Secret so given that one is going to die, the veil is good, but if there is a chance of living the veil is bad?

@DavidZ Ok just saw your answer, short answer, not a Bessel... I thought it was supposed to be a Bessel and maybe showing you how it could be one could have led you to something: reverse-engineering an unexisting result

@Secret .ugh... bullet in the brain was my suggestion.

Yes as it is the most peaceful way to die. But if (s)he is meant to live, then you can do nothign about it, which reminds of the hopeless cases how the pepetrator always win at that moment of harming some victim

i see

@Secret Who is meant to live?

i getcha now

8:32 AM

There are cases of gunshots on the brain that are not necessary fatal

like if you see someone being murdered

you'd rather see them being burnt cos u can at least try and stop it

yes

user228700

Crap. What'd I miss?

@G.Bergeron Oh... indeed my expression was not a Bessel function. It's merely expressible in terms of Bessel functions.

harry potter talk

8:32 AM

@Kaumudi WTF that's sick

@Kaumudi diffrent forms of death - very nice

user228700

@G.Bergeron Huh? O_o

in the wizarding realm

The key to how intense I felt the emotion of nihilation is how reversible a decision is given we are not 100% sure whether it is meant to be

user228700

@JohnRennie :-D Ikr?

8:33 AM

@Secret there is always hope remember

noone knows for certain the veil is the end

@Kaumudi You're wishing a somebody on the brink of being murdered to be burned at the stake on the off chance he won't die... I'm sorry but this seems like extremely convoluted logic

well you can kinda argue that as the souls still exists in the underworld. thus in principle they can be retrieved

@Secret I don't think any of that happens

user228700

@G.Bergeron What? I think u're confusing me for somebody else who may have suggested that. Dude, I just came in!

@G.Bergeron What? Are you getting your conversations mixed up again?

8:35 AM

@Kaumudi Yes

I'm referring the wrong person as you reacted in a way Secret could have

@Kaumudi do you really believe that

disgusting

no kamudi is not

@G.Bergeron you should be more careful ;-)

jks

user228700

What is happening? I didn't react to anything! I'm still reading the transcript!

8:36 AM

@DavidZ Yeah well its only a chat box

kamudi is a lot more hopeful soul than mine

Is it me, or is it (slighty) curious that MM.SE has awarded more Socratic badges than we have?

Burning at the stake is OK as long as you don't overdo it. I don't like my meat well done.

physics.stackexchange.com/help/badges/196/socratic

I don't think she is suceptible to the emotion of nihilation

8:36 AM

they're two years younger and have half as many questions

To everyone Kaumudi is innocent, I pointed at him wringly 8D

@Secret also note the bullys don't allways win. In the long game they often lose

user228700

*her :'-(

2

@Mew That is true, but the damage has been done, as many research shown

@Kaumudi Sorry pointed at her

8:37 AM

gender is irrelvant here

For my case, I even recoinciled with those who bullied me and are friends now, but the emotion is still left behind like a scar

ture

Actually no I referred to Kaumudi because you posted right above the person I wanted to answer to and then things spiralled out of control

@G.Bergeron ur just digging a deeper hole mate

and this scar: The overwheming desire to turn everything in the world into nothingness, because it is the most perfect thing possible, and the only way I knew that can counter that emotion, despite the paradoxical feeling that I actually like all this world had to offer

8:39 AM

@Mew I'm just being honest

please apologize to Kaumu

@Mew I did

user228700

Okay, @Secret: How the hell dyou know so much about that veil?!?!

I always google, and there's a harry potter wiki that collects all that information

@G.Bergeron you didn't apologize

@Secret how is nothing perfect?

8:41 AM

@Mew About what? him/her: yes

user228700

@Secret It's really weird, how you speak of the veil as if it's something that u have known in reality.

At the risk of talking about physics, what do the panel think of this question? I'm inclined to close it as either homework or unclear:

0

Q: Are front speed of light, phase speed of light, or group speed of light equal in all directions?

Is the speed of light equal in all directions? (If so, why? If not, why not?) Please discuss and explain separately for "light" in the sense of the signal front (referring to "the earliest appearance, the very first indication" of a signal being noticed), and for "light" in the sense of an ele...

special-relativity waves electromagnetic-radiation metric-space

@Kaumudi I apologize for the misunderstanding

ty

because it is the most uniform thing. where everything, including those incoporeal concepts you cannot punch a fist on to give them a lesson, will all be rendered meaningless, thus in a sense they will lost their game for the first time since eternity

8:42 AM

@JohnRennie Definitely homework-like

user228700

@G.Bergeron No problemo. Happens all the time :-)

@Secret if the universe was at some stage nothing, then nothing inevitibly leads the universe

and if the univertse ever forms nothing again, and nothing forms a universe, a new universe will form

@Mew But ouch you are intense... I am sincere in my apology but I would think such a situation is more funny then anything else

@Mew Nooooooooooooo you've been reading stuff by that heretic Penrose!!

user228700

Wokay, ::slowly creeps away as conversation takes a turn for the worse:: Nihilism? No, thank you very much.

8:44 AM

it does not matter, I only want to teach that incorporeal thing a lesson and make it taste a notion of loss for the first time. That's the only way I can gain revenge against that emotion I don't like

@JohnRennie no does he say the same? this is my own idea

Conformal cyclic cosmology

The conformal cyclic cosmology (CCC) is a cosmological model in the framework of general relativity, advanced by the theoretical physicists Roger Penrose and Vahe Gurzadyan. In CCC, the universe iterates through infinite cycles, with the future timelike infinity of each previous iteration being identified with the Big Bang singularity of the next. Penrose popularized this theory in his 2010 book Cycles of Time: An Extraordinary New View of the Universe. == Basic construction == Penrose's basic construction is to connect a countable sequence of open Friedmann–Lemaître–Robertson–Walker metric (FLRW...

@Kaumudi what is nihilism?

@JohnRennie Physical nihilisim is absurd

Political nihilism maybe not so XD

ty @JohnRennie

user228700

8:45 AM

@Mew U really don't know?

i really don't

@G.Bergeron you are obviously have real problems keeping track of which concversation is which ...

Crap!

Again!

I know it's not you I just click to quickly

@G.Bergeron please apologize to John

@Mew The belief that nothing really exists

8:46 AM

oh

@Mew I recommend the book. I think you'll find it a fascinating idea. Penrose points out that the short time and long time limits of the universe both have conformal symmetry, and he speculates that they can be identified.

Ugh no

lol

@Mew give it a rest

it was a joke mate

@G.Bergeron nihilism sounds sillly

user228700

8:47 AM

@Mew Well, it's the idea that there is no meaning to this world. That we are in an existential rat race to forge meaning from absolutely everything, when the supposed "truth" is that we cannot know anything for sure and therefore, there are no values, no morals, etc.

@Kaumudi but that's wrong isn't it?

@Kaumudi This, I believe, is true

@G.Bergeron u believe in nihilism?

Well actually, I am only straw nihilistic when I felt that emotion. Otherwise I am actually agnostic

user228700

@Mew There's no way to prove it.

8:48 AM

and I am actually rather optimisitc about the future

I am a very polarised soul where multiple contradictory thoughts can coexists at the same time in my brain

if there is no meaning in the universe, why would a universe form in the first place

@Mew As it relates to absolute meaning, yes completely

user228700

Anyway. I do not particularly enjoy speaking about nihilism so toodles!

tooodloo

The criticisms of nihilism seem to be based on the view that just because morals are a human invention they have no value. I don't see any justification for this. A nihilist philosophy doesn't mean you have to be a miserable person.

2

8:50 AM

@JohnRennie I'm certainly not miserable

my theory of motivation is that (A) happiness is due to having the confidence to overcome threats/obstacles and (B) pleasure is overcoming threats/obstacles

where threats/obstacles = physiological or existential threats

clearly one can be happy without morals

but I still believe there is meaning in the universe

or it wouldn't bother to exist

ok it seems nihilism is the wrong word. This is my urge whenever I felt strongly of that emotion:

tvtropes.org/pmwiki/pmwiki.php/Main/OmnicidalManiac

@Mew Pay atteantion to my phrasing, I say there is no ABSOLUTE meaning.

it's the same idea as: hoping all of this unpleasantness is a nightmare, placed on a more objective scale

@G.Bergeron yes but relative meaning makes no sense

I believe absolute meaning exists

8:52 AM

@Mew How is that?

not necessarily relative morals

morals are a human invention

but meaning can be objective

"The universe exists" has a meaning outside the human mind in my opinion

it is an objective real feature \

@Mew Yes and as such can never be absolute. That doesn't imply I have no morals, as a social animal I obviously have an effective moral code wether I would want it or not and I have no problem with that

@G.Bergeron I'm not syaing morals are absolute

I'm saying some "meanings" are absolute tho

@Mew I know I am just answering sequentialy

@Mew morals have a gauge symmetry? :-)

8:54 AM

12 mins ago, by Kaumudi

@Secret It's really weird, how you speak of the veil as if it's something that u have known in reality.

I have no idea why I always known to give this impression. Probably because I can always speak volumes of whatever concept is being described, and that amount o detail make it felt real

wat's that @JohnRennie

The point about moral, though is a rationally think it has no basis, but meh whatever

@JohnRennie what's the conserved current? :D

@G.Bergeron of course there is a rational basis for morality

have you heard of the social contract theory?

@JohnRennie I think it is not abelian though hard to rationalize

8:55 AM

@Mew their absolute value has no physical meaning. Only their differences can be observed :-)

oh

@Mew I never signed anything that is just evolution and me being part of a social specie

@G.Bergeron non-commutative morals?

@G.Bergeron of course you didn't sign anything, but if you've heard the theory it explains why it can be benficial to have morality in a group

@JohnRennie I am sure we can work out something here :D

8:56 AM

That means you have to be nice to me but I don't have to be nice to you. Right? :-)

now because of this benefit, those with the trait of morality could be genetically selected to suvive

@Mew That's the point of a social specie: cheating at game theory

@Mew It doesn't mean that it is rationally justified because who said that what evolution lead us to is what ought to be?

@G.Bergeron who says "rationally" justified means doing what "ought" to be done?

it just means you can rationally explain why things are done

there's no "ought" involved

@Mew With respect to what you said there, this is not meaning for me it's just a fact

@Mew That is understanding why it's there

well one must fully define meaning if one wants to understand if there is meaning in the universe

8:59 AM

If my goal is to be an asshole, then moral would come against my goal

@Mew I thought you meant meaning along the line of "we are meant to be"
