@BalarkaSen Yeah, Twilight!!! Damn. I can't imagine a worse love story plot. Liked the visuals though.

Secret

btw, this is what I want to post originally before seeing the vampire barging in, hoping to entertain mathers with something pretty

Now my mood is all screwed. I am going to do some metric stuff to chill

Fun fact: There's a maths user called MATH ASKER, but interestingly he does not behave like a help vampire

Q: Meaning of a remark by Heisenberg: Die "Bahn" entsteht erst dadurch, dass wir sie beobachten

In a paper by Joos and Zeh, Z Phys B 59 (1985) 223, they say: This 'coming into being of classical properties' appears related to what Heisenberg may have meant by his famous remark [7]: 'Die "Bahn" entsteht erst dadurch, dass wir sie beobachten.' Google Translate says this means something ...

CC @ACuriousMind

dmckee

@EmilioPisanty Tough call. It's technical language, so you wouldn't expect every German speaker to be able to provide a correct interpretation—it calls for someone who know how German is used in talking about quantum mechanics.

Emilio Pisanty

@dmckee yeah, it's a tough call

@Kaumudi.H laptop still OK?

Yepp :-)

John Rennie

@Kaumudi.H I recently discovered that to import any second hand consumer electronics to India needs as a special form called a no objection certificate

user228700

Oh, wow! :-o

John Rennie

Which we didn't have! But we got away with it :-)

user228700

YESSS! :-D

I have heard of NOC

John Rennie

I suspect TNT did us a favour there, even though they were a bit crap at actually delivering it.

I remember 'no objection certificate' from Hera Pheri :)

John Rennie

Basically sending anything to India is a total pain. Unless of course you lie :-)

But there's a limit to what you can label as holiday photos!

It's too late for maths now

Litmus the UK spacerock band?

Balarka Sen

Late?

Family going to bed at 10 PM is so much worse than jet lag.

John Rennie

Litmus (band)

Litmus are a London-based space rock band formed in 2000 by Martin (bass guitar/vocals), Simon (guitar/vocals) and Ben (drums), joined the following year by Andy Thompson (keyboards, 2001–2007) and Anton (synths). Matt Thompson joined on synth (2002–2004), while Marek replaced Ben in 2003. Oli Mayne (keyboards) joined in 2008, then left in 2010, along with Anton. As of November 2012 the line-up is Martin Litmus (bass/vocals), Simon Fiddler (guitar/vocals), Marek Bublik (drums) and James Hodkinson (keyboards/effects). They are influenced by mid-1970s Hawkwind and Black Sabbath, amongst others. They...

I think u can get a rough estimate, COVFEFE is 7 characters, probability of a 7-character length string being exactly that is $(1/26)^7\approx 1.2\times 10^{-10}$ so I guess you would have to type approx a billion characters to start getting a good chance that COVFEFE appears.

Balarka Sen

Without clicking on that from the past 8 minutes of my life I guess it will be <30 seconds long.

@ooolb Consider the hyperbolic space $H^n$ with the standard metric. Compute $$\inf\left\{\left(\int u^{2n/(n-2)}\right)^{-(n-2)/n}\left(4\frac{n-1}{n-2}\int|\nabla u|^2+\int Ru^2\right): u\in C^\infty_c\setminus\{0\}, u\ge0\right\}$$

It might be $-\infty$.

Balarka Sen

The answer is "Wait but why?"

CooperCape

I was going along those lines ^^

0celo7

@BalarkaSen sorry if you were in our discord you would know

@ooolb It's unlikely to be $-\infty$ since $H^n$ has bounded geometry so Sobolev embedding works as expected. Construct a metric that blows up near infinity (incomplete is probably necessary) so that the inf is in fact $-\infty$.

I suspect $R$ needs to be unbounded below.

Balarka isn't a true communist

he does it for the memes

ACuriousMind

It's a statement, not a math problem. What do you need help with? ;P

0celo7

ask @ACuriousMind

Sid

@ACuriousMind Give a counter statement to prove it is not.

Balarka Sen

@Sid Yes, true.

ACuriousMind

@Sid Why would I? Maybe the communist is a hypocrite. Maybe they aren't. Whether you're a hypocrite for eating at McD depends on whether you called for a boycott of McD previously, no?

Balarka Sen

Eating a McDonalds is equivalent to embracing the capitalism.

Owning an i-phone is worse

Marx debunked i-phones yeaaaaars ago

ACuriousMind

Bernardo Meurer

gnu.org/software/hurd

One of the survivors, poking around in the ruins with the point of a spear, uncovers a singed photo of Richard Stallman. They stare in silence. "This," one of them finally says, "This is a man who BELIEVED in something."

obligatory xkcd

It's GNU's kernel, it's been in the works since before Linux was a thing, and somehow not ready yet

Balarka Sen

@Sid Eating glamorous and expensive food on a regular basis and not as a necessity would mean you're embracing consumer fetish and capitalism, yes. That doesn't inherently prevent you from being a communism, but it does have an ironic implication.

Bernardo Meurer

0celo7

6:39 PM

I don't.

CooperCape

Reckon you could make a discord bot that mathjaxes for you maybe

user228700

I see.

Balarka Sen

To sum it up, eating at McDonalds and owning i-phones is neither a crime not does it prevent you from being a communist.

CooperCape

That might require some html fiddling though I doubt that's possible through the io.

thing

ACuriousMind

@Sid Eh. I think there's plenty of room between "I think capitalism is a detrimental regime and think we could be better" and "I hate capitalism and will never go near anything associated with it", yet the former is still conceivably communist.

Balarka Sen

6:40 PM

It just adds to the evidence of support of the arguably false claim that the person is embracing capitalism to some degree.

0celo7

regime

ACuriousMind

Not all beliefs need to be held with fanatical fervor

0celo7

@ACuriousMind are you being ironic? Capitalism is freedom, the opposite of a regime

Balarka Sen

More importantly, communism is not a black-and-white belief

DanielSank

Welp, Southern California is burning to the ground again.

Bernardo Meurer

6:42 PM

People only hate capitalism until they eat a nice juicy Big Mac while hungover

Then you understand what it's all about

DanielSank

If I don't make it, @BernardoMeurer you can have my rep points.

And @0celo7... I love you.

ACuriousMind

@0celo7 Maybe it's the wrong word, I meant "regime" in the sense of being an organizatorial structure of society, not in the sense of "dictatorial regime".

dmckee

@0celo7 The structures that are usually called "capitalism" in the world today are not the philosophical simplicity of "you are free to trade as you see fit".

Bernardo Meurer

@DanielSank This actually constitutes a contract, we even have witnesses :P

It comes encumbered with a lot of dross around the idea of a government chartered corporate entities. To distinguish them you might call that "Corporatism" (as some people do).

Bernardo Meurer

6:43 PM

I really hope I don't come back to a pile of rubble

0celo7

I have a feeling that these people are calculating modulo higher order terms

Hmm

Balarka Sen

@dmckee In fact, that's closer to the idea of a free market economy, which is a proposed alternative to postmodern capitalism.

0celo7

@ACuriousMind Maybe California will burn and sink!

Bernardo Meurer

I went to see the fire when it started

DanielSank

Are we talking about political/economic systems?

Bernardo Meurer

Ventura looked like mordor

0celo7

All we need is a magnitude 10 earthquake

Then CA will break off like a piece of parmesan

Bernardo Meurer

@0celo7 Has that ever happened?

Then we can end up with people arguing is favor "Communism" who distance themselves from, say the USSR and red China, and people who arguing in favor of "Capitalism" who distance themselves from, say the US and the Europe Union.

0celo7

@BernardoMeurer probably not

but god works in mysterious ways

@BernardoMeurer I just heard a report that Capenteria is being evacuate. I just can't wrap my head around that: the place is a bunch a beach shacks with a city government.

Balarka Sen

not really

it just has to click

ooolb

then how do you know if you like a song

ah

how would you put it into words in first order?

Balarka Sen

I mean there's no specific criterion, but there's surely an algorithm of sorts

lets see

ooolb

8:39 PM

figure it out and share

Balarka Sen

since I come from a rock n' roll background, the first thing is that I prefer a tonal continuity. I don't like beats as much as I like a riff or something atmospheric (that's mostly why I don't like a lot of rap)

I think I liked Madvillany because it had nonstandard rhyming styles and Madlib's composition

CooperCape

Maybe you'd like a bit of Tchaikovsky...

Balarka Sen

I have heard a thing or two by him. My knowledge of classical music is not systematic

it's just not my thing

you can't making a sweeping generalization on minimal like that

everyone thinks symphonic = classical

simply not true

Bernardo Meurer

@ooolb You're being pedantic

CooperCape

what about

So the classical symphony

Bernardo Meurer

Sure, orchestral music is not always classical

Balarka Sen

Mhm, true.

CooperCape

is ummmm not classical?

Or you just saying not all symphonies=classical

Bernardo Meurer

8:52 PM

But by now it's perfectly acceptable to use them interchangeably almost

ooolb

no

if you say classical people think of like bach

but this music is nothing like that

Bernardo Meurer

Ravel is by no means classical, yet people call it classical music nonetheless; and it's okay

Balarka Sen

I get ooolb's point.

CooperCape

Well that's completely wrong

Bach isn't classical at all

ooolb

now you're being pedantic

Balarka Sen

8:53 PM

lmao

CooperCape

No

bolbteppa

Why is the graviton spin 2, beyond hand-waiving, sense is, you do the gravitational waves thing of reducing $R_{00} = 0$ to $g^{\mu \nu} g_{\rho \sigma,\mu \nu} = 0$ for a weak gravitational field in harmonic coordinates, with solution $g_{\mu \nu} = \varepsilon_{\mu \nu} e^{ikx} + \varepsilon_{\mu \nu}^* e^{-ikx}$, then magic?

CooperCape

Bach is firmly baroque

Bernardo Meurer

@CooperCape Is correct

ooolb

is this ironic

Bernardo Meurer

8:53 PM

Bach is the Baroquest

Why do you think they call it "bachroque"

Balarka Sen

I didn't know this chat was capable of having a Rick&Morty level conversation

I underestimated @ooolb

ooolb

what did i do

Balarka Sen

started a rick and morty level conversation about music

Bernardo Meurer

@ooolb You were pedantic

ooolb

as far as I can see this is an ironic conversation and it's supposed to be funny

CooperCape

8:57 PM

No it's not?

I love a good music chat

Bernardo Meurer

Fight me

ooolb

i get called pendantic for generalizing the world classical music which is not even wrong

then you act pedantic by saying bach isn't classical

CooperCape

Bach ISN'T!

He literally died before the earliest point you could call classical.

Bernardo Meurer

If your standard is "Only music that is classical in style can be called classical independent of performance", then Bach is not classical

Balarka Sen

what is the difference between classical and baroque

ooolb

8:59 PM

different periods

different instruments

but baroque is also loosely referred to as classical
