omg I can't stand this anymore

terribly bad answers given and yet they're upvoted as hell and most of the time accepted

see the 2 answers at physics.stackexchange.com/questions/398476/… they're wrong in that they claim things that don't deform much won't bounce. I gave the example of steel that doesn't deform much but bounces pretty well and I'm getting ridiculized. what the heck

or this accepted and top voted answer 16 votes!!! physics.stackexchange.com/questions/398184/… which doesn't even address the question!!! The correct answer has only 9 votes.... what the heck

we need to expose those attrocities so that noobs can upvote and downvote correctly, turning the tables to improve the quality of answers

nicael

I'm going to edit my answer regarding deformation, I realise I'm not really correct. I'm just editing my pics.

Regarding my answer with "16 votes", you're not right, it's correct.

no_choice99

good. I will upvote it if it's correct

I know it's correct, I didn't say the contrary. I said it doesn't addresses the question.

while the answer that has now 10 votes does addresses it

nicael

Here you misunderstood the original problem. In order for you not to be angry, I rephrased it yesterday.

no_choice99

Ok, I am quitting PSE. This is disgusting. You erased the question that you did not answer. And the edit got approved. Bye all. I'm out of this place.

I demand to be banned and remove all my points

You could delete your account, if you wish. There's a link in your profile.

No, I still want my questions and answers here.

@David Z are you here?

@DavidZ

please read the above DavidZ and ban me + remove all my points. Thank you very much

@ACuriousMind will be glad to help you

although I think the policy is you have to delete yourself

no, they just get a user[number] attached to them

they discourage deleting all of your questions and answers

@no_choice99 If you delete your account your posts will still exist, just dissociated from any profile.

1:28 PM

thank you

0celo7

you are free to delete everything manually

nitsua60

If you try to delete all your Q&A many will be impossible, and many would get undeleted. (Because they're not yours, technically; you've given them to SE and if the community things they're good additions to the site you don't get to unilaterally override that.)

@0celo7 They have the ability to, but should not.

0celo7

Why shouldn't they?

skullpatrol

0celo7

the SE policies are truly strange

nitsua60

@no_choice99 I believe if you delete through your profile there's a non-trivial "wait period." Maybe a day or two?

I.e. "delete me!" puts your account in a queue to get profile scrubbed, posts disassociated, &c. in a little while. Because so many people change their mind and it was a huge hassle for SE staff to re-link up things for rage-quitters who then regretted it.

nitsua60

1:43 PM

@skullpatrol Assume Good Faith. You're taking it personally, but there's a good point @0celo7 could be making about how chat-flags are seen by any 10K anywhere in the (SE) system, which might not be the right criterion to use for chat-moderation.

0celo7

Everyone who can flag has mod powers

nitsua60

So go ahead and ask for clarification before assuming badly.

Fabby

@0celo7 Nope. Everyone can flag.

0celo7

@nitsua60 I simply cannot assume good faith given some of the ridiculous flags I have received

Fabby

and then it calls in all active >10K users.

0celo7

1:44 PM

@Fabby So they have mod powers.

Fabby

@0celo7 nope.

0celo7

Yep!

You're in the wrong here

nitsua60

@0celo7 Yet you must, if you're to be part of making the place good rather than bad.

Fabby

Nope, they can flag and then the high-rep users get called in, they look at what's going on and then the mods decide whether to ban both of you,

one of you

0celo7

How is "assume good faith" even a thing when there are completely ridiculous flag storms on a regular basis

Fabby

@0celo7 You haven't been banned yet.

nitsua60

@0celo7 Not true.

skullpatrol

nitsua60

1:47 PM

@0celo7 False.

Fabby

we're still talking to you...

0celo7

@nitsua60 My claim is that anyone who flags without saying something is acting in bad faith. Most people do not say anything. Therefore, most flaggers are acting in bad faith.

Fabby

but you need to take a few deep breaths.

This is the H bar for Christ's sake!

This should be all about Physics, logic and science.

nitsua60

@0celo7 I'd say you're acting in bad faith if you claim that. Why don't you assume that the flagger doesn't know better, and use your words to try and make the problem better?

Fabby

not about emotions....

0celo7

The h bar will be deleted just like Mos Eisley.

Fabby

Now, that's a place lots of flags came from.

We're perfectly calm.

Fabby

Cya

nitsua60

No. That's not a reasonable interpretation of the system. For a bunch of reasons.
(a) I think we agree that the anonymous nature of chat-flagging is troublesome, so it's not a "good" enough system to hold to that sort of stricture;
(b) there are *always* new users coming on board, and we must be patiently instructive, always;
(c) even if *I* feel like enough words haven't been used, I should assume the flagger is frustrated by dealing with dreck for years and feels they've used their words enough.

So we can't even know if a flag is "wordless," my "wordless" may not be yours, and I may not have seen all the words.

0celo7

@nitsua60 I've never actually had anyone complain to my face, I just get random 90 minute bans for saying "wtf"

The abbreviation, not the full thing.

Balarka Sen

@nitsua60 I actually did delete a number of my older posts which got highly upvoted by the community but were actually pretty garbage when looking back in retrospect. (There is an objective notion of deciding if a certain answer is garbage in math.SE: If, eg, the calculations are wrong.)

So it indeed is a flaw of the system if it intends to keep numerous wrong answers up and running in the site.

(None of my deletions got undeleted, btw)

0celo7

@BalarkaSen I must not understand what drama is. How is this drama?

Othello

Othello (The Tragedy of Othello, the Moor of Venice) is a tragedy by William Shakespeare, believed to have been written in 1603. It is based on the story Un Capitano Moro ("A Moorish Captain") by Cinthio, a disciple of Boccaccio, first published in 1565. The story revolves around its two central characters: Othello, a Moorish general in the Venetian army and his unfaithful ensign, Iago. Given its varied and enduring themes of racism, love, jealousy, betrayal, revenge and repentance, Othello is still often performed in professional and community theatre alike, and has been the source for numerous...

And it makes complete sense when you think of their business model. They're a company and need to bring in money to keep the lights on/platters spinning.
They've decided to do that through a mixture of advertising and job placement services.
To do *that* they've got to get lots of eyeballs here.
To do *that* they've gone ahead and created (IMO) the finest system for expertise-based Q&A the internet's yet seen.
We're not the audience, we're the product.

There are some exotic non-mainstream theories in physics which do involve negative mass, but I'm not authoritative enough to speak on them. Anyhow you could extend that line of questions to even "Why two? Why not three?". The simple answer is we don't know. It's just how nature is. Sure, maybe there exist (or will exist) elegant theories which generalize it, but the basic fact still holds.

Mathematical analysis

Mathematical analysis is the branch of mathematics dealing with limits and related theories, such as differentiation, integration, measure, infinite series, and analytic functions. These theories are usually studied in the context of real and complex numbers and functions. Analysis evolved from calculus, which involves the elementary concepts and techniques of analysis. Analysis may be distinguished from geometry; however, it can be applied to any space of mathematical objects that has a definition of nearness (a topological space) or specific distances between objects (a metric space). =...

@BalarkaSen Oh of course not, consider $\{z+i,z+2i,z+3i,\dotsc\}$

this is not a normal family

@Blue Hah yeah, afraid so. =P

@Nat Haha. Nevermind. I should actually be busy too, but I am procrastinating. :P

Do get back when you're relatively free though. Your answers are normally very good.

@BalarkaSen unabomber not far )( from here o_O

@Slereah (wow!) wonder if hes related to the physicist. famous for inventing 1 qubit diagrams. o_O en.wikipedia.org/wiki/Felix_Bloch

Felix was Swiss.

@Blue right. & families are known to cross country boundaries.

Well, if you are willing to consider long-distance relations, then possibly. People sharing the same surname usually have a common origin in history.

vzn

@Blue right. some surnames are more/ less common than others. the media sometimes amuses itself with these weird connections. eg think the new british princess (meghan markle) has a "colorful" geneology.

how nice that André Bloch was spared from failing the class due to lack of preparation by convincing his teacher Ernest Vessiot to give him an oral exam.

lol aka ~6 degrees separation "mixed bag" wow o_O express.co.uk/news/royal/885954/… dailymail.co.uk/femail/article-5130473/… harpersbazaar.com/celebrity/latest/a13988049/… history.com/news/henry-viii-beheaded-meghan-markles-ancestor

I used to fail the class classical mechanics due to lack of preparation but I didn't have the chance to convince my professor to give the me an oral exam. I think I know well those material in classical mechanics but I just lack time to prepare for the exam that time.

I was also late for that exam for an hour.

because my watch was late for an hour.

@vzn I suspect you'll enjoy this one blogs.sciencemag.org/pipeline/archives/2018/03/30/…

↑ also this is quite remarkable

@EmilioPisanty They seem to have a Twitter profile and an active blogspot

Emilio Pisanty

@Blue indeed s/he does

it's just the byline to a pseudonym, and particularly a blog one, that I find interesting

It's a bit weird though. PLOS One has a reasonably high impact factor, but yet allows anonymous authors.

Anonymous

@EmilioPisanty True

Emilio Pisanty

@Blue there's a difference between anonymous and pseudonymous

just because PLOS ONE isn't telling you their full legal name doesn't mean that they don't know who the person behind the handle is

Anonymous

Pseudonyms can normally be traced back to find a person's real name though. This person seems to have left no traces of their real name on their blog/profile :P

@EmilioPisanty Ah, yes. That's true

@EmilioPisanty lol back on spking terms? your msgs are hidden but thx for the ref. yep citation analysis is a lot like scientific genealogy. my two favorite examples EPR1935 & Turing1936, remarkable how 2 paradigm shifting papers were only 1 )( yr apart.
