Q: Will MOXIE get clogged or chemically degraded by martian dust?

MIXIE, the Mars Oxygen ISRU Experiment is an experiment on the Perseverance rover currently on its way to Mars, that will test solid oxide electrolysis as a way to extract oxygen from atmospheric carbon dioxide. As such its solid oxide fuel cell (run in regenerative mode, i.e. "backwards" to prod...

I don't know what perchlorate is exactly but it's a reported constituent of martian soil in some places at least.

What is the most appropriate way to approximate in chemistry numerical for jee like while solving percentage constituent to empirical formula how to properly take approximation for getting correct ratios

Avyansh Katiyar

06:06

@sheltonBenjamin It's just ratio and proportion

The more shortcuts you find right now

Well

Just be prepared to memorize all of them before the exam

M.A.R.

13:47

@sheltonBenjamin I have no idea what's being asked. Are you looking for shortcuts to calculating the arduous multiplication of big numbers or?

shelton Benjamin

17:13

@M.A.R. no i am asking for appropriate way to approximate things by the way i found after solving so many numerical that if you take three digit after decimal then answer almost everytime doesn't deflect is it correct?

Wha

@sheltonBenjamin just go by significant figures

Q: How do we get g and E values for various levels to calculate electronic partition function

When we calculate electronic partition function using the formula: $$q_\mathrm{elec}=\sum^\infty_{n=1}g_ne^{-E_n/k_BT}$$ How can I get the $g_n$ value and $E_n$ values for $n=0,1,2,3...$ levels? I need to calculate the $q_\mathrm{elec}$ for various species like $\ce{H, H2, OH, H2O, O2, O, O+, H+}$.

How does the positive question record work? I still don't have it showing maintained. Does it have to be continuous days? Like I post a good quastion on day 1 then bad question on day 2, good question on day 3. Does the streak show 1 or 3 days?

Q: Ways to determine the concentration of alkyl halides in organic solvents

I have a volatile alkenyl bromide dissolved in hexanes. I have to use the halide in a Grignard reaction but separating it from hexanes is hard (the bromide is light sensitive and very volatile). I would like to use the solution of the halide in hexanes but I don't know how to determine its concen...

M.A.R.

@Safdar No, both criteria for the badge have to be maintained, other than that, I think it's consecutive questions with a score above zero and that's it

Maybe not even consecutive

Anindya Prithvi

@M.A.R. Consecutive ques above zero do not work well...either it has to be all of positive votes or zero vote.

M.A.R.

Well the only types of complaints I remember about the Curious et al. badges in people shitpost a dozen questions and then wonder why they don't get a badge

Safdar

A: Why was the "curious badge" badge not being awarded?

It seems you do not fulfill all criteria, namely you miss the 'positive question record.' You are informed about this when you click the progress bar. This may be due to you having some deleted questions; from those visible it seems you would fulfill it but it is close enough to be plausible th...

M.A.R.

@Safdar genau

So other than that, maybe it's just caching

@Safdar so your issue was positive question record or?

Safdar

19:35

@M.A.R. Yeah, I need 5 more positive questions as of now to even get it to zero.. :|

M.A.R.

HA HA HA

Anindya Prithvi

@Safdar youre at negative?

Safdar

@AnindyaPrithvi -5

M.A.R.

Meh, if you're aiming to be active, recurring badges are much easier to aim for

Anindya Prithvi

@Safdar how? did you delete quesrtions?

M.A.R.

19:36

Post good stuff that gets 10 votes. Much better than Curious

Safdar

@AnindyaPrithvi I have 2 closed, 1 D, 1 N (just one question is 1 C, I N, 1 D) So i need 8 to balance it out.

@AnindyaPrithvi My first question.. It got trashed almost immediately.

Anindya Prithvi

@Safdar same

@Safdar closed as duplicate

Safdar

@M.A.R. There aren't many good stuff that isn't googlable at my level since it has already most likely been asked before..

M.A.R.

Shakes head newbs. You should post clickbait HNQ crap instead.

Anindya Prithvi

whats HNQ?

M.A.R.

19:38

If you're going for badges, that is. Maybe possibly there's a more noble goal in mind.

Safdar

@M.A.R. I've made HNQ crap.. All you have to do is upvote the question poster after posting your answer..

M.A.R.

@AnindyaPrithvi Hot Network Questions

@Safdar Keep making HNQ crap!

Safdar

How do you think I have so much rep so quick on Chem SE?

Anindya Prithvi

Multiple acc?

M.A.R.

Because you're handsome.

3

Safdar

19:40

@AnindyaPrithvi nope. If you pay respects to the question poster after answering with a proper answer.. It automatically puts it in HNQ unless there are 2 questions from the site already.

M.A.R.

@AnindyaPrithvi That's a minefield

Anindya Prithvi

@M.A.R. whats a minefield when you can fly with onions

Safdar

Only works on Chem SE and on completely new questions that have a positive score.

M.A.R.

That does not seem like a great idea either. They're not aerodynamic.

Anindya Prithvi

@M.A.R. you didnt understand an onion

M.A.R.

19:42

To avoid detection, you either have to be so slick and slow that not having socks to help wouldn't change much, or you'd be discovered one day

Simple: There's a barrier for voting, limits to the number of votes, and the detectors at least check how many times a user has voted for any other users on the site.

user434058

@M.A.R. Seems like an advice from an experienced guy/girl! ;-)

M.A.R.

@AnindyaPrithvi I admittedly did not

Anindya Prithvi

@M.A.R. unregistered ID are abandoned in 30 days, you need pretty less Rep to upvote ....sooo

M.A.R.

@FakeMod Experienced in smelling burnt noses, but mine's intact

Safdar

Btw, how do you get an unregistered account?

Anindya Prithvi

19:44

@Safdar ask a question

on incognito

M.A.R.

Unregistered accounts are tied to cookies

user434058

@M.A.R. Nice analogy there, really turned on my visual cortex.

Anindya Prithvi

But dont do it with the same device, even if you do not interfere with primary account, there will be a log about that

@M.A.R. Tails

M.A.R.

If an account's deleted, the votes are transferred to Community and any rep gain is lost

CMs make an exception for certain accounts.

Anindya Prithvi

@M.A.R. +1 vote is enough to attract more votes if its a decent answer

Safdar

19:46

@M.A.R. If You were to delete then?

user434058

@M.A.R. Will they make for mine? O_O

M.A.R.

@AnindyaPrithvi Not as strong an effect as you think. Unless the site is ELL or something.

On Chem, we're grumpy and would downvote it even more

Safdar

@FakeMod I don't think it gives you the rep back. it just doesn't recalc for others I think..

Anindya Prithvi

@M.A.R. seen people on MS

user434058

@AnindyaPrithvi Not true!

M.A.R.

19:47

@AnindyaPrithvi Math?

Anindya Prithvi

@FakeMod for chem se...MSE

yaa

I have seen wrong answers at +5

correct was at 2

M.A.R.

@FakeMod I've always seen groupthink thrown around as an argument on metas, but there's rarely any evidence for it.

Anindya Prithvi

@M.A.R. I did as well

M.A.R.

@AnindyaPrithvi That proves nothing

user434058

@Safdar Yeah, I won't get my rep back, but would all my votes get thrown off? (I know they will, but dunno how high you need to get to assert your votes' permanence)

Anindya Prithvi

19:48

@FakeMod +160 is not good

M.A.R.

@FakeMod Pretty darn high. And there's no algorithm for it, the CM would have to make the exception manually

And it's been happening much less frequently AFAICT, preservation of votes.

user434058

@M.A.R. TBH, there are many drive-by votes on active sites (Math, SO,etc.) Not really common among the peasant-sites.

Anindya Prithvi

yes

Safdar

@M.A.R. So if ron were to delete his account what would happen?

user434058

@M.A.R. Ah, Skeet level!

Anindya Prithvi

19:49

@Safdar he is a mod i thinl

M.A.R.

@FakeMod Drive-by yes. There are idiots who'd upvote anything in the proximity to get vox populi and suffrage

Safdar

@AnindyaPrithvi nope... He decided not to stand..

user434058

@AnindyaPrithvi What +160?

Anindya Prithvi

@M.A.R. thats what i said

M.A.R.

But I haven't seen any evidence it's a substantial effect.

@AnindyaPrithvi Groupthink is different

Anindya Prithvi

19:50

@FakeMod 16 upvotes on a specific profile are not enough to preserve votes

M.A.R.

Groupthink

Groupthink is a psychological phenomenon that occurs within a group of people in which the desire for harmony or conformity in the group results in an irrational or dysfunctional decision-making outcome. Cohesiveness, or the desire for cohesiveness, in a group may produce a tendency among its members to agree at all costs. This causes the group to minimize conflict and reach a consensus decision without critical evaluation.Groupthink requires individuals to avoid raising controversial issues or alternative solutions, and there is loss of individual creativity, uniqueness and independent thinking...

user434058

@M.A.R. At least they would stop once they get the badges. Few folks are, however, chronic drive by (up)voters.

user434058

@AnindyaPrithvi Meh, that's just the Chemistry profile.

M.A.R.

There's always the risk of blind leading the blind, wrong answers getting upvoted etc. But each site has a core userbase of answerers and editors that also happen to vote the most.

user434058

Physics profile nearly has 2000 votes.

user434058

19:52

@M.A.R. The saviours!

Safdar

What if @Mithoron deletes his account? Where would the downvotes go??

M.A.R.

They often quench most of the possible effects of bad voting. Bad voting often happens to be signal noise, not the pervailing phenomenon

Anindya Prithvi

@Safdar Gone, reduced to atoms

Safdar

@AnindyaPrithvi He has 21 K downvotes

M.A.R.

@Safdar Attributed to the community, although people would want his votes preserved

user434058

19:53

@Safdar They would be transferred to the Downvoting Devil's account! Bwahahaha....

Anindya Prithvi

@Safdar 42000 rep change of Chem se...in a single day

just for downvotes*

M.A.R.

Well, most of that is 1 rep folks who were downvoted into oblivion gaining 0 rep from the reversal

But it'd hamper Roomba's function.

user434058

"Upvotes are too mainstream, try downvoting!"

Anindya Prithvi

MSE is mostly positive

M.A.R.

Everywhere upvotes dwarf downvotes

Anindya Prithvi

19:54

there was a time on CSE when I say negative questions on home page

rather say non-positive

user434058

Well, TBH, I don't really have a low enough up/down ratio. Mine is 3.5

Safdar

@M.A.R. We have -28000 deficit according to data SE.. so I wouldn't say so..

M.A.R.

You can run a few queries on SEDE. Chem would only be exceptional in its closing rate

@Safdar Hah, really?

user434058

@M.A.R. Do you close a lot?

M.A.R.

No, I don't participate on the site much these days

Anindya Prithvi

19:56

@M.A.R. PSE and MSE both have good closing rates as well

Safdar

Also why do you guys (above 3000 rep) not use all your close votes?

user434058

@M.A.R. Oh, not specifically you, rather the site (since you said it's exceptional in its closing rate)?

Anindya Prithvi

@Safdar 1Q/day

Safdar

@AnindyaPrithvi You have 20 votes I think..

user434058

@AnindyaPrithvi 24 CV/day

M.A.R.

19:57

@FakeMod Last I checked, a year and a half ago, it was 50+ % closing rate

We were the second site in all the network

user434058

@M.A.R. Hmm... Higher than I expected. PSE must have a lower rate.

user434058

@M.A.R. That's an achievement in itself. Great!

M.A.R.

IIRC closing rate correlated fairy well with how moderation-prone the site is.

Math was higher than I expected but the influx of crap was showing

I don't remember, 23% maybe

@FakeMod Eh, I was of the opinion we close too much

Will probably arrive at the same conclusion today.

user434058

@M.A.R. Closing rate highly depends on policies and the userbase, (question askerw and closers) IMO.

M.A.R.

We have to both filter some questions before they're accepted (ban HW forever? Probably too drastic) and not close whatever we think sounds rudimentary

Safdar

20:00

@M.A.R. we have less bad questions showing b/c of that..

M.A.R.

Or at least be consistent in doing so.

user434058

@M.A.R. TBH, I like closing bad questions. Assuming that you guys also closed bad questions, you did a goid job of keeping the site clean.

M.A.R.

I also like closing bad questions.

It's about nuking the bad stuff and keeping the good stuff, there's no disagreement here.

user434058

Ban complete HW sounds too strict to me. Ban shitty HW, sure!

Anindya Prithvi

@M.A.R. Only the radioactive stuff stays behind

M.A.R.

20:02

Last I checked though, which was long ago, quite a few questions were closed as homework that weren't obviously HW.

Safdar

https://chat.stackexchange.com/transcript/message/55342669#55342669

Nvm this was completely skewed. This included bounties.

According to Data SE upvote:downvote = 304304:90489

M.A.R.

Problem arises when one of these rudimentary questions ends up being popular and not getting closed. It's morally itchy.

Anindya Prithvi

@M.A.R. And then that question goes for a bounty

user434058

@M.A.R. Yeah, that's a problem when the policies aren't objective.

M.A.R.

Well, bounty shouldn't stop nothing. Mods can remove bounties from questions and spank the author.

user434058

20:03

@M.A.R. And it serves as an example for all future meta ranters to show, whenever their (similar) question gets closed.

M.A.R.

@FakeMod They're never going to be fully objective, that's why you need humans closing questions. We can always make decision making more straightforward and more easily consistent, though

user434058

@M.A.R. "spank" Why are you so visual? :P

Anindya Prithvi

@FakeMod Organic chemist?

Safdar

@FakeMod btw, aren't meta tags burninated? PSE still seems to use homework-and-exercise

user434058

@M.A.R. But it is good this way, I think. At least better than any other radical alternative.

user434058

20:05

@Safdar Meh, I am just guessing, but around 50% of the meta questions on disputed closures would be about HW questions.

Anindya Prithvi

@Safdar (physics.stackexchange.com/questions/tagged/…

user434058

@AnindyaPrithvi Yeah, makes sense. Nucleophile spanking the electrophilic carbon. Makes a lot of sense.

Safdar

@AnindyaPrithvi physics.stackexchange.com/questions/tagged/… You mean this?

Anindya Prithvi

@FakeMod I dont know if it was sarcasm

@Safdar perhaps, wasnt able to put it like click here

M.A.R.

@FakeMod well, it's easier to be critical than correct. We tried coming up with a solution for four years, I'm none the wiser

user434058

20:08

@AnindyaPrithvi No, I was just trying to be sarcastic and, at the same time, acknowledge the truth of your comment. Confusing move.

user434058

@M.A.R. True!

Safdar

Can mods see what you have deleted?

Anindya Prithvi

@FakeMod Outstanding Move

M.A.R.

@Safdar Mods and room owners, if you're referring to chat messages

Mods have a way of ICBMing stuff so no one except mods sees it. And they can move the messages to a private room and then delete the audit message.

Safdar

@M.A.R. So you can see then? I assume you are one of the room owners since you've been here for the longest time. You've been here since private beta right?

user434058

@AnindyaPrithvi Too mainstream! ;-)

Anindya Prithvi

@FakeMod Stop, you'll leak our plan!

M.A.R.

@Safdar People with italic names in chat are ROs, mods have blue names.

user434058

Room owners cannot probably see deleted messages.

Anindya Prithvi

user434058

M.A.R.

@FakeMod You're not squinting hard enough

user434058

@M.A.R. You stole that from jcole, didn't you?

M.A.R.

@FakeMod Yes

You can see message history for deleted messages.

If not generated automatically, like for messages that don't get edited, you'd have to type the URL manually.

user434058

20:14

@M.A.R. oh! Never did that!

Anindya Prithvi

Or you can run a full time log script on Chat.SE to preserve everything
