It didn't get flagged as Unclear, did the history of science tilt it in favour of "off-topic" that much?

Anonymous

@EmilioPisanty I mean for example astronomy is much easier to understand than astrophysics. But at research level it's equally difficult to make a discovery in either of the fields

Sir Cumference

> implying astronomy and astrophysics aren't equivalent

Phase

@0celo7 didnt see your message

I have wednesdays off

Anonymous

@SirCumference Are they equivalent?

Anonymous

I guess not

Sir Cumference

14:01

Modern astronomy is entirely physics :P

Emilio Pisanty

@Phase well, it's clear enough what the question is

it's just bad

and off-topic

so

DV

and flag for closure

resp.

Phase

If there are multiple flags though for diff things do they add?

Or do they have to be the same category

Anonymous

@SirCumference Some people just work on simulating stuff and instrumentation, etc

Emilio Pisanty

you can only flag each post once

Phase

@EmilioPisanty ik

Emilio Pisanty

14:02

more precisely, you can only have one active flag per post concurrently

Phase

I'm talking about if N many users flag differently

Sir Cumference

@EmilioPisanty I still have no clue what "It can be something from real life or with any accident." is supposed to mean

Emilio Pisanty

@SirCumference presumably they're talking about the Newton-and-the-apple myth

Phase

@SirCumference have you ever been so far as to have gone decided what to look more like law of physics?

Sir Cumference

@Blue As opposed to what, working on paper? :P

Emilio Pisanty

14:03

@Phase if the flags are different types i.e. close vs VLQ, then they work independently

Sir Cumference

@Phase what?

Emilio Pisanty

they'll just put the question on both queues

Anonymous

@SirCumference Yeah. Making instruments using previous technology isn't that difficult compared to having to understand astrophysics

Phase

Ah i see. What happens if a post gets repeatedly flagged, but a moderator doesn't intervene. Will it still be closed?

@SirCumference ?

Emilio Pisanty

@Phase no, it won't be closed no matter how many <3k users flag it

Sir Cumference

14:04

@Blue Ah, well making the instruments is the job of engineers

Emilio Pisanty

it needs mod intervention or 5 >3k close votes

Phase

@EmilioPisanty I'm powerless :'(

Sir Cumference

@Phase I don't think that's a proper English sentence...

@SirCumference Those guys don't call themselves engineers though :P

Anyhow...

Emilio Pisanty

14:05

but if it has a ton of flags then it will appear earlier on the queue

Phase

@SirCumference It's a reference to a meme of an ancient civilisation

Emilio Pisanty

and more importantly it needs to get on the queue to begin with

so

flag

Phase

@EmilioPisanty is it worth being 10k+, given the implicit responsiblity?

Emilio Pisanty

@Phase what implicit responsibility?

Sir Cumference

@EmilioPisanty Yeah that makes sense, but "it can be something from real life" is bizarre.

Emilio Pisanty

14:06

i.e. associated with 10k as opposed to 3k?

@Phase well, didn't you use to have an account with rep?

Phase

Well, either I suppose but 10k'ers have features that 3k'ers don't, right?

idk this site is confusing at times

Emilio Pisanty

@Phase a few

Phase

I had an account with 500 rep

Emilio Pisanty

@Phase what happened to it?

Phase

I uh.. deleted it

long story

Balarka Sen

14:07

@ACuriousMind @JohnRennie I have started reading the first book? in the Culture series by Banks, "Consider Phlebas". Not sure how far I'll get but I'm going to try it.

Emilio Pisanty

@Phase so... don't delete it next time?

if community moderation is something you want to take part in

Phase

@EmilioPisanty I'm not complaining about being low rep

Well

Emilio Pisanty

just sayin'.

Phase

It would be nice to know if I'll lose chat privileges if I go under 100

Because if so I can start posting again

0celo7

we can boost your rep

just like headshots back in the modern warfare 2 days

Phase

14:08

@0celo7 with the sockpuppets

0celo7

get that fall camo

@Phase Yup

I actually got someone to accuse me and see if the mods could find them

I'm 100% clean

Emilio Pisanty

@Phase it's hard to comment on your rep status since your profile doesn't make sense without non-public info

Sir Cumference

The only truly irrevokable reputation in SE is the rep from the association bonus. In general you can theoretically lose your privileges.

Phase

@0celo7 Idk about that, you're 300 stone and american

Emilio Pisanty

presumably you have 200 rep in an account that's not shown in your network profile

0celo7

14:09

@Phase I have a sponge on a stick

Phase

@EmilioPisanty nope

None of my accounts have 100+ rep

Emilio Pisanty

@Phase what's stopping you from posting now?

Phase

The fact that idk what'll happen if my rep goes sub 100

Emilio Pisanty

@Phase is this your user?

Phase

@0celo7 does it reach the really hard to reach places

@EmilioPisanty yeah

Christianity is currently my highest network profile..

Emilio Pisanty

14:10

@Phase I have no idea where your 101 rep comes from

Phase

Association bonus of my old account

Emilio Pisanty

... which you then deleted?

Sir Cumference

@Phase You can easily bring it back up most of the time, for better or for worse. For answers, a single upvote takes five downvotes to undo.

Phase

Propogating forwards from association bonuses with other SE accounts I made after my physics was higher

0celo7

@Phase yes

Phase

14:11

I didn't delete all my SE's just physics and maths

0celo7

I could describe the process but it would be NSF$\hbar$

Phase

@0celo7 I figured an engineering man about town like you would've made a bathing robot

0celo7

@Phase god bless

Emilio Pisanty

so... you made a physics account, got 200 rep on it, opened other accounts, got the 100rep association bonus, deleted your physics account, kept the 100rep bonus on the other network sites, then reopened a physics account, and it still gave you the bonus?

Phase

seems so

It's not an intentional exploit or anything tho

pls no ban

Emilio Pisanty

14:12

that's a good candidate for the bizarrest SE behaviour I've seen thus far

bizarrest? bizarredest?

Sir Cumference

@EmilioPisanty That does happen. It's generally a problem since people whose rep goes below their starting 101 can delete their accounts and start over. I've seen it happen a lot on Astro.

Phase

@EmilioPisanty Psychologically or Just in terms of the SE system?

Emilio Pisanty

@Phase as in stuff the SE system does that I would not expect it to do

Sir Cumference

Even further, they can repeatedly bounty questions and delete their accounts on sites they don't contribute to.

Emilio Pisanty

@SirCumference yeah, that's a good point

anyways

Phase

14:14

Honestly I also feel too Overwhelmed to write an answer

Balarka Sen

@0celo7 Do you want to figure out the h-principle thing? I think I kinda see what's going on.

Emilio Pisanty

@Phase what's stopping you from posting?

Sir Cumference

@EmilioPisanty I remember a question getting bountied for an entire month on Math.

Phase

the usual calibre of user is a really high standard, and I feel like anything I write will either be a duplicate or a poor question by comparison

Sir Cumference

Eventually it did get an answer, but the bounty had no penalty.

Emilio Pisanty

14:15

@SirCumference surely the second bounty (if it gets noticed) is grounds for moderator action?

0celo7

@BalarkaSen I'm reviewing homeworks for an exam in 50 mins

hmu later

Emilio Pisanty

@Phase the only way to get good at writing answers is to write answers

Phase

@0celo7 good luck, bring your AR into the exam room in case things go bad

Sir Cumference

@EmilioPisanty Evidently it didn't. And it was a popular question.

Phase

@EmilioPisanty I meant questions

Balarka Sen

14:15

@0celo7 Ah, for sure

Phase

@EmilioPisanty if there are basic questions I can usually answer them. I don't see many these days though

Emilio Pisanty

@Phase the only way to get good at writing questions is to write questions

Phase

: P

Sir Cumference

Any site specific bans are erased when the account is deleted anyway, so SE's staff would need to feel it necessary to intervene with a network wide ban.

Emilio Pisanty

seriously, just ask

the duplicates thing is easy to cover by just having a proper search

and if the question isn't great then the only thing you have to do is be receptive to the feedback and act accordingly

Sir Cumference

14:17

@EmilioPisanty Then there's this

Q: Comment votes can be easily gamed by users with the association bonus

When someone deletes an account, the upvotes they left on comments are not removed. When they create another account, they can upvote these comments once again. This is a problem, as you can give a comment as many upvotes as you want by: Upvoting the comment Deleting your account Repeating 1 a...

Which triggered a massive argument

Emilio Pisanty

@SirCumference yeah, I remember that

0celo7

@Phase ok school shootings are probably not a good topic for this place

Emilio Pisanty

I agree that it's a bug but I agree with SE that it isn't worth a massive system redesign

Phase

@0celo7 whoa where did you get that from

Dude you should delete your comment that's just rude

Emilio Pisanty

@Phase perhaps you should clarify what you mean by AR?

Phase

14:19

This clearly

Augmented reality to parse and solve equations

Emilio Pisanty

@Phase 0celo7 presumably parsed that as AR15, and I kinda agree that that's a more immediate reading

I have to wonder how judges are picked when their preferences can obviously differ. Someone who hates cinnamon, etc. might not like dish that most people would consider good.

Phase

14:44

@0celo7 watch this, the intro will resonate with you when he talks about free market

Anonymous

That's why they have three judges...not one.

Sir Cumference

@Blue Three to decide what makes a dish objectively good. Two out of three could dislike a dish solely because they don't like a common ingredient, when the execution is done well

You'd need your judges to enjoy a really wide array of common foods

Idk

Anonymous

@SirCumference Uh, well. Some degree of bias will always be there. Nothing to do about that.But think of the real world scenario. Not all your customers will have same taste either. So, if two judges dislike your food, pretty good chance that a major portion of customers won't like your food

Anonymous

They could increase that number to 5 or 7

Anonymous

I don't think that'd help much

Sir Cumference

@Blue Eh, I wouldn't project the opinions of three people to hundreds of customers :P

There are some judges who dislike everything XD

Mithrandir24601

@SirCumference if you have food prepared by a good chef (I mean, like, michelin quality), you can still appreciate how well it was made and all, while simultaneously disliking every ingredient

0celo7

14:52

I've been to one Michelin star restaurant

It was pretty damn good

Mithrandir24601

So a good judge might not like the ingredients, but could still tell how well it was made etc.

Anonymous

@0celo7 Which one?

0celo7

Also like $40 for every entree

@Blue I don't remember the name. It was French

Sir Cumference

@Mithrandir24601 Well, as an example, the food I can never stand the smell or taste of is brussel sprouts. Yet that's a common ingredient. I don't think I could get through a dish, no matter how well prepared, with a smile

I'd imagine there are similar examples just about everyone, including the judges, has

Mithrandir24601

@0celo7 same. Sat Bains. Unbelievably fantastic :D I also had the good fortune of, during my Masters, being near a cafe that a michelin chef started up. I couldn't resist going every week :)

@SirCumference go to somewhere with at least one Michelin star before making such comments ;)

@SirCumference I’d imagine they wouldn’t have that ingredient in the pantry then.

neat

Emilio Pisanty

not great

but not terrible either

Phase

15:05

dang

Emilio Pisanty

I don't understand why you don't just analyze things in the tube's rest frame and then transform back

but to each their own

generally, the rule of thumb in QM is that stationary potentials are much easier to analyze than time-dependent problems, so you don't want to inflict additional pain on yourself if you can at all help it

and, on the other hand, if the tube is not moving with constant velocity, then... yeah, that's not the kind of problem that makes the Wikipedia list of solvable stuff

Phase

Oh

RIP

@EmilioPisanty thanks for the run-down though

Emilio Pisanty

@Phase no, just leave it

if question bans are something you're worried about, deleting this post won't help

@EmilioPisanty I wasn't gonna delete it, not until I have a good reason to at least

It's more just about not being able to chat

@Phase You can always create 20 accounts on 20 different SE sites for 20 rep

@Phase Mostly, the problem with the question is that it's not particularly clear what you want answers to look like

@EmilioPisanty I did consider that as I was writing it

Denis

hi, I have a bit of a general question about academia and stackexchange

Emilio Pisanty

@Phase indeed it is

which is why context is crucial

Phase

@EmilioPisanty like references?

Denis

Suppose I am interested in the answer to a question because it is linked to my current research, and I even put a bounty on the question to motivate people
Then I figure out the answer I am loooking for. Since I want to include it in a paper, should I post it on stackexchange ? will it be problematic later when I want to publish material that is already public ?

Emilio Pisanty

15:13

@Phase no, like what you already understand and what you don't

if you don't know the material well, then you don't know what parts of your existing understanding are relevant and which ones are not

Phase
