Would this answer qualify as a haiku? :D

A: Is there any quantum effect which we can see in the every day real life?

This place is dotted with so many incandescent bulbs that I feel so hot.

2:02 PM

@FakeMod Not really. Haiku are supposed to have a 5 / 7 / 5 syllable structure, although some writers do deviate from that rule. I suppose you're asking in reference to the recent MSE poetry contest, meta.stackexchange.com/q/349555/334566

@Sophie Are forces real or are they only mathematical tools? ;) I can't observe forces directly (although I can observe springs being compressed or stretched) but I can observe accelerations.

2:33 PM

I realise that this question is terrible, and we don't have a Lacks Minimal Understanding close reason, but why on Earth is it closed as non-mainstream? The OP wasn't seriously proposing that those events do occur in negative time, he was just bewildered by the notation.

@PM2Ring The close votes were 2 non-mainstream, 2 needs details or clarity, 1 custom.

@ACuriousMind Ok. Thanks.

1 hour later…

3:37 PM

Tbh neither "non-mainstream" or "needs details or clarity" apply to that question imo, it's not really ambiguous what the op is confused about and almost anyone on this site could have given a good answer, I'm not sure it deserved to be downvoted into oblivion and closed though

4:12 PM

I'm getting pretty lost on the gauge transformations of coordinates in GR. I understand that in EM there is an infinite and continuous degree of gauge freedom, but in GR it appears we are only making an infinitesimal modification to the coordinates. I don't see how we have a large amount of freedom in this in the same way we do in the EM guage.

What do you mean by "infinitesimal modification"?

@DavidZ 2 months ago (May) when I checked, Physics.SE had 110 questions/day. In June I saw it at 90 questions/day. Today it says 85 questions/day. Do you know the reason for the decrease in activity?

Perhaps "infinitesimal" is the wrong qualifier, I might just mean "small".

user434058

5:01 PM

@NikeDattani Maybe fewer people are in quarantine right now :-)

@FakeMod But Chemistry was at 19 questions/day in June, and they're at 20 questions/day now.

user434058

@NikeDattani Another factor might be that many exams would have been conducted by now. I don't have any quantitative data, but during the pandemic, I have seen a higher increase in homework-like questions than the increse of questions in other categories. This can be easily explained by the closing down of universities and schools, and the simultaneous nearing of exams in many parts of the world.

@FakeMod I guess so, although chemistry.SE has not been affected in the last month (in fact they seem to have improved a bit). Maybe someone that can see the analytics might be able to tell us if this is "really" an anomaly, or if 110q/day in May and 80/day in July is normal based on previous years.

user434058

@PM2Ring Thanks. I knew it wasn't a haiku, but: "I can sit on a chair and not fall thrugh. Also, sapphires are blue. Would this answer qualify as a haiku?" rhymes unexpectedly well ;-). However, I was completely unaware about that MSE question :-)

user434058

@NikeDattani Yeah, mods and >25k users will be more capable of analyzing it.

5:11 PM

What about FakeMods?

user434058

@NikeDattani The data they fetch isn't really trustworthy, more often than not, they just plainly fake the data ;-)

@FakeMod I see.

user434058

Damn! I really need a nice reply/tagline whenever my name is used like this :D

Why do so many mods love being on the right-hand side so much?

user434058

@NikeDattani ILLUMINATI CONFIRMED!!!

5:15 PM

Yet another application of the right-hand rule

user434058

@NikeDattani Easy-peasy, 'cause all the mods are rightists. (Obligatory confession to avoid any turmoil: Jk, PSE mods aren't rightist)

dmckee is on the left, which is maybe why he is labeled as "ex-moderator" ?

user434058

@NikeDattani His case is a special one. He willingly left quite a time ago, but SE hasn't taken his diamond away yet.

5:56 PM

@FakeMod How does the community feel, about this user having access to 203,000 email addresses, and the IP addresses of wherever they go? Do I want this user to know that I'm visiting my grandmother in Birmingham, or at a conference in Germany, or with my daughters on a vacation in Mexico? Do I want this user knowing where I am all the time (unless I turn off my phone and sign out of Stack Exchange), and how do the other 203,000 users fell about it?

I don't know him (haven't been very active on Physics.SE until after he left), so I have no idea.

user434058

@NikeDattani TBH, he is completely inactive, AFAIK, in every sense. And moreover, as I hear from other people, he's a good guy and can be trusted. As for me, I don't mind anyone knowing where I am.

user434058

I'm the Philosopher until someone hands me a burrito.

user434058

FWIW, I am that burrito guy :D

@PM2Ring I think real is a problematic word. Too many negative connotations and too poorly defined

that's why I said material

@FakeMod You also don't have your real name and picture on here do you?

6:11 PM

@NikeDattani The community is usually good about telling us when they want an inactive diamond gone, see e.g. physics.meta.stackexchange.com/q/11105/50583.

user434058

@NikeDattani No, I don't :-) I can feel the insecurity (forgive me for my callousness) if I would use my real name.

@ACuriousMind Do you have any insights about why our questions/day dropped from 110/day to 85/day between May and July? On Chemistry it's gone up from 19/day to 20/day in the last month.

@NikeDattani My interpretation is: Jul to Oct is always the slowest quarter of the year, and the usual May/June finals spike was exaggerated this year due to the pandemic

@ACuriousMind You can see the analytics, you don't need to show it to me, but is Jul-Oct always the slowest quarter of the year, if you look at the past history?

@NikeDattani Yes, the drops are comparable to the drop around Christmas every year.

6:19 PM

@ACuriousMind I see. Although I think the Christmas drop is only a couple weeks in late December / Early January, whereas what we're talking about right now is a few months (July to October)?

@NikeDattani Yes - I think it's the summer holidays in universities around the Northern hemisphere

@ACuriousMind I see. I'm curious then why Chem.SE has gone up in activity from June to July, but that's a question for them.

@FadedGiant is here though?

I think you need to look at the pattern at least in the context of an entire year - the data comparing individual months is very noisy

@ACuriousMind I don't have access to the whole year's data on Chem.SE but I do see that I was able to ping Faded Giant / Loong.

@NikeDattani When I look at the page views per month, June, July, and August are the lowest.

6:56 PM

@FadedGiant Makes sense. So both Physics and Chemistry dropped, but Chemistry was affected less than Physics. Chem dropped by only about 10q/day while physics dropped by 25q/day. But as a percentage drop, they are really not much different.

@ACuriousMind We have our scientific speculation Codidact site up and running (and we've noticed that dmckee's decided to join!) - would you be interested(/would it bother you) in having a community ad for it?

(or rather, potentially having such an ad, if people upvoted it enough :P)

@Mithrandir24601 We've also had ad suggestions for PO, so I don't see why this one would bother us, either

Q: How can I reopen the question as community wiki post?

This post is closed by a moderator. I think the reason is that it starts to have too many answers which I didn't expect. How can I reopen this question? I want to convert it to Community wiki post but I don't have any option in the edit box.

10:59 PM

@NikeDattani I don't think I have anything to add to what the others have already told you on that point.

@Mithrandir24601 Interesting, why is it not called Worldbuilding?

Mithrandir24601

@ACuriousMind Nice, thanks :) I'll add it to the meta post soon :)

@NikeDattani There is a Worldbuilding SE site and it did stem from this (I guess you know that already?) but on reflection, the Worldbuilding SE site had certain issues about how its scope became less and less well-defined over time, in part as it's not strictly a scientific site (e.g. questions about magic are on topic, although the 'HNQ effect' played a part as well)

11:15 PM

@Mithrandir24601 I was aware of the Worldbuilding SE site, but never quite understood what "worldbuilding" meant, until I went there and spent some time really reading about what the site is about. Still I'm no expert in it. However when I saw "scientific skepticism" it immediately reminded me of our Skeptics SE, which is also not very clear what it's about until you read the Meta post which says that what they mean by "Skeptics" is "Scientific Skepticism".

Mithrandir24601

Largely though, there are things on topic on a site called 'Scientific Speculation' that aren't strictly 'Worldbuilding' and we just wanted a site with a more scientific focus

@Mithrandir24601 I see. Honestly when I saw the name, I immediately thought of the "Skeptics" site, but when I looked at the questions I was a bit confused, then read the description which basically reminds me of the description I read long ago about Worldbuilding.

The users are automatically created from the SE profiles?

Mithrandir24601

@NikeDattani For me, Worldbuilding was the first site I really used on SE but to be honest, I never really understood what Worldbuilding actually is until listening to some of Brandon Sanderson's lectures - after that, I do admit to feeling that the scope of the SE site isn't really what I'd actually call Worldbuilding (but maybe that's just me)

I've never used Skeptics, so I have absolutely no idea what's in scope for them :P

@Mithrandir24601 Ok then you've convinced me that worldbuilding is not the best name for the site.

I had no idea what it was anyway, so I'm taking your word for it.

Mithrandir24601

@NikeDattani Well, I don't believe that it's the best name, but for all I know, I could be wrong

11:22 PM

@Mithrandir24601 The "tour" page and FAQ of Skeptics.SE will help you understand why "Scientific Speculation" made me think that your site was a clone of Skeptics.SE rather than Worldbuilding.SE. In addition there is this Meta post:

5

A: Definition of "scientific skepticism"

The site tour uses the term scientific skepticism. Presumably this is the source that you are asking about. The Tour points to the Welcome to New Users FAQ question. The Welcome to New Users FAQ question expands the meaning: Scientific skepticism? This site is about applying scientific skepticis...

skepticism / speculation, not so different

slightly different, but somewhat related

Mithrandir24601

@NikeDattani Yeah, we import posts (on some criteria, varies per site) and if a user has written a post, an account for that user gets created but it's associated to a fake e-mail unless that user comes and claims that account by linking it to their SE account

@Mithrandir24601 How do I claim my account? I see that there's an EE site on Codidacts

I actually do have a question on EE.SE

36

Q: Why does Intel's Haswell chip allow floating point multiplication to be twice as fast as addition?

I was reading this very interesting question on Stack Overflow: Is integer multiplication really done at the same speed as addition on a modern CPU? One of the comments said: "It's worth nothing that on Haswell, the FP multiply throughput is double that of FP add. That's because both port...

cpu computer-architecture alu floating-point intel

Mithrandir24601

@NikeDattani If you click on your profile (on the top right-hand corner), then 'edit', then scroll down to the bottom of the page (well, above the footer), there's a 'Link with Stack Exchange' header and I believe if you click that button, it'll tell you what to do (I've forgotten beyond that already...)

@Mithrandir24601 I'm confused, I did ask this question on ElectricalEngineering.SE, but I don't see it on the Codidact version of EE.

Mithrandir24601

@NikeDattani Ah, yeah, EE started with a 'blank slate', so opted to not import anything

11:31 PM

@Mithrandir24601 Are other sites going to be migrated there too?

Mithrandir24601

@NikeDattani With time, probably. It's on users to come to us and say that they'd like a site (see Site Proposals) really - we're not affiliated with SE or anything, so we don't want to spam people, but word's gradually getting around that we're up and running

So that's basically like an A51

Mithrandir24601

Yes! A51, but implemented differently - we don't need sample questions or a list of users. The process goes differently depending on whether you already have a community (straight to proposal, after a bit of discussion and voting, the site gets created) or not (create a 'site idea' and see if people are interested, if we get some reasonable amount of interest, then it moves to a proposal)

@Mithrandir24601 When did all this start?

Mithrandir24601

@NikeDattani There are a few different starting points, really - the first was a few years back (maybe around 2015-2016?) when ArtOfCode created a Q&A site (but didn't do anything with it), then when 'The Mess' happened last year, a bunch of people essentially quit SE and decided to start this up properly (around October-ish), then a few months ago, we decided to use Art's implementation and move forward with that. We got the actual site up and running maybe a couple of months ago?

11:45 PM

I saw Monica's Meta post about Codidact on the Writing.Meta, but I didn't know it was an entire network.

Mithrandir24601

It's small but we have a few sites running now :)

Still working things out of course, but we're getting there

@Mithrandir24601 I'd be careful importing user names from SE, it has made people really angry in the past.

Mithrandir24601

@tpg2114 Hmm, might be worth asking Art to hide them or something...

It's just an FYI -- you guys can treat it however you like. Just letting you know so you can avoid souring people's attitudes toward you before you even get going :)

@ArtOfCode

Mithrandir24601

11:59 PM

@tpg2114 Yeah, thanks :) Souring attitudes isn't something we want to do, but I have no idea how difficult such a thing is...

(or if there are other reasons not to)

@tpg2114 Thanks, appreciate the pointer. Unfortunately this is not something we have any choice over - if we don't import the usernames publicly, we're in breach of the license.
