@Slereah Who's the sun

Is that you?

Slereah

It is Lubos Motl

@AvnishKabaj You seriously don't recognize PSE's official mascot? Be ashamed! :P

Is this supposed to be material for that community ad?

user351417

@AvnishKabaj How do you make that thing though?

Slereah

@Chair I'm def posting it next time there's a community ad thread

Hello guys

If a quantum system admits two different phases, it makes sense to define the "full Hamiltonian" of the system?

Anonymous

@Chair Just copy paste the site URL.

newUser

For example, if I define a state in a phase, which Hamiltonian should I use to evolve this state?

@Slereah You can suggest it for this time's thread too...

@Blue This is a cool feature.

where's the current thread?

Captain Bohemian

what on earth is the BPS state in string theory? I have seen this state is mentioned in a ton of papers, like it is so important in some way.

@CaptainBohemian welcome in the jungle

How did lubos motl become the mascot

According to legend, one 19th century attempt at curry resulted in the invention of Worcestershire sauce.[37]

The creators were the chemists John Wheeley Lea and William Henry Perrins,

Slereah

Motl is here

David Z

@AvnishKabaj He's not actually the mascot

For a while he was the highest-rep user on the site

Emilio Pisanty

btw @DavidZ I take it Manish is aware of the ongoing discussion on Meta? (I would imagine that you've pinged him on the mod chat room.)

David Z

12:55

@EmilioPisanty We've pinged him, yes. I couldn't say whether or not he's aware.

A: Spacetime surgery - why are there unglueable points?

HOW DOEST ONE MAKE THE DEUTSCH-POLITZER SPACETIME A good question because it's not 100% the standard procedure of a cut and paste spacetime (a good reference on cutting and pasting manifold is by the way C.T.C. Wall's Differential Topology. There is indeed not a lot of good references for GR on ...

Gratuitous use of non-Hausdorff manifolds

Emilio Pisanty

@DavidZ hmmm.

the conversation would very much benefit from his presence.

But I guess we can't force him to answer there.

user351417

@EmilioPisanty I don't think he'd notice that ping in the mod room if he gets multiple pings every day (which is likely considering the number of 3k+ accounts he has on different sites) and the number of sites he moderates, but checks in very rarely. That ping would just show up in his global inbox, right?

Avnish Kabaj

@DavidZ I'm not as dumb as I look

I am a good liar though

Blue's site needs one more vote

Slereah

Heyyyy

Krasnikov published a book last year!

Heck yes

I'm buying that

"Back-in-Time and Faster-than-Light Travel in General Relativity"

I'm hyped

@Slereah what's with the all-caps title?

Slereah

@EmilioPisanty the razzle dazzle

Avnish Kabaj

Mildly weird I agree

It is ridiculously warm in Chester this afternoon. Right now it is 16°C. At this time of year it would normally be around 5°C. Not that I'm complaining :-)

Hmm, Stacks has a nice Grammar and Mechanics section.

@dmckee It's more like southern-central rather than eastern

@Blue I suspect this is standard for most organizations the size of SO with significant user interaction, as far as how the style guide looks like

but it is indeed remarkable that they've open-sourced their style guide

Anonymous

17:46

@EmilioPisanty Well, that isn't so surprising given whole of Stacks is open source. :P

ACuriousMind

The funny thing is that the standard template for suspensions says exactly what that guide says you shouldn't do :P

Anonymous

@ACuriousMind Heh, yeah.

Emilio Pisanty

@Blue that's just passing the buck, innit?

ACuriousMind

The "Use sentence casing for all headings and calls-to-action." is also rather inconsistently followed...

Emilio Pisanty

I mean, there was no real need to include the comms style guide in the technical CSS and HTML opensourcepalooza

@ACuriousMind you should raise that as a bug on meta.SE

17:48

@EmilioPisanty Ah, I see your point.

Emilio Pisanty

though you should have a defense plan of action in place

@EmilioPisanty They'll first have to get past the lowercase, but fierce, ß guarding my home

LOL

ACuriousMind

People sometimes think it's a snake because of the hissing sound, but it's really a ßnake.

Emilio Pisanty

@ACuriousMind what if they bring an uppercase ß?

(if I understand correctly, that would cause language to explode, right?)

ACuriousMind

17:53

@EmilioPisanty What good is a two-year old gonna be? (The uppercase ß was accepted into German orthography only in 2017)

Emilio Pisanty

@ACuriousMind was it actually?

I guess the last time I checked was before 2017, then

I thought it was a non-existing chimera

what does it look like?

ACuriousMind

@EmilioPisanty Yes

Emilio Pisanty

@ACuriousMind omg

that document is horrifying

I mean

German is Hard

Legal German is Harder

German text about the German language is also Harder

this is a text in legal German about legal German

that's getting close to the level of ridiculous where the whole thing just implodes into a black hole of inscrutability

> Das „Amtliche Regelwerk der deutschen Rechtschreibung“ liegt in einer aktualisierten Fassung vor.

what's that "vor" doing at the end, eh?

ACuriousMind

hanging out

Emilio Pisanty

is it, perhaps, maybe, just maybe, waiting out there at the tail of the sentence to ambush the reader with a complete change in the meaning of the core verb of the sentence?

and f*s that's only the first sentence of the text

ACuriousMind

18:01

As much as I'd love to defend the honour of my mother tongue, I gotta run ;)

Emilio Pisanty

@ACuriousMind ah, shame, that

happy running

It's like someone briefly joined the team running the universe, introduced their idea for a cool mechanic, then left, and now everyone is stuck pretending that this wildly unbalanced dynamic makes sense.

that's an interesting point

@EmilioPisanty German is not easy for sure but at least you can guess how it is written by how it is spelled/spoken (if spoken correctly).

@EmilioPisanty unlike English

Emilio Pisanty

@pZombie well... yes, but only mostly

if you don't know what "blumentopferde" means, you cannot pronounce it

i.e. if you've been fooled into thinking that Blumento is a place, then it will not sound like anything like has to do with flowers

pZombie

@EmilioPisanty "liegt vor" is quite twisted. Translated 1:1 it means "lies in front", in your case however it has the meaning of exists. It gets only worse when you consider "es liegt vor mir" meaning "it lies in front of me" yet if you say "es liegt mir vor" it has more the meaning of "i have it in front of me" but with a much lesser importance about the direction compared to the former case

Emilio Pisanty

@pZombie presumably that's some conjugation of vorlegen, in the sense of "to submit"?

pZombie

more directly translated it would mean put forward

vor as in forward and legen as in lay down

or put down in front

i wonder myself why languages are so complicated and allow for so many different meanings of the same word but i am no linguist. I guess there has to be a reason or smarter people than me would have fixed it

Emilio Pisanty

@pZombie why would this need to be "fixed"?

Lojban

Lojban (pronounced [ˈloʒban] (listen)) is a constructed, syntactically unambiguous human language, succeeding the Loglan project. The Logical Language Group (LLG) began developing Lojban in 1987. The LLG sought to realize Loglan's purposes, and further improve the language by making it more usable and freely available (as indicated by its official full English title, "Lojban: A Realization of Loglan"). After a long initial period of debating and testing, the baseline was completed in 1997, and published as The Complete Lojban Language. In an interview in 2010 with The New York Times, Arika Okrent...

this is what happens when you try

it's... shall we say, it's only usable by a certain type of people

pZombie

19:15

@EmilioPisanty Why is it only usable by a certain type? It seems like it would make a lot of things easier, especially when trying to program AI

or translators

Emilio Pisanty

@pZombie it's not a natural language

if you can learn it, then (seriously) good for you!

pZombie

there is no point in learning it for me if there are not enough others to agree on learning it

Emilio Pisanty

but over time, as I understand it, it's become clear that it's precisely that super-logical structure that makes it hard to learn for most people

pZombie

it would not be of much use then

what makes it hard is that parents don't speak it while you are being raised

or people around you while you grow up from childhood

Emilio Pisanty

@pZombie you're welcome to do your own research

As I understand it, Lojban has been reported by most learners to be much harder than natural languages

(as in, you know how people can learn other natural languages than their mother tongue)

That may well be because lojban has yet to develop an active speaker base

But I'd be very surprised if any logic-oriented constructed language can acquire such an active speaker base and retain its logic

pZombie

19:33

@EmilioPisanty A lot of people will say something just because it feels right rather than them understanding each word of the sentence they composed.

or the precise meaning of what they said

like "war is good for the economy", every Joe sixpack will agree to that because he heard it or read it a lot but when you ask them to explain why exactly this is the case, you will most likely get as many different explanations as people which said it.

so yes, every language gets corrupted to some extend because we are only humans but a language like Lojban which was designed to be logic-oriented can be recovered to a less corrupted state more easily
