@ACuriousMind never mind

@ACuriousMind MGSV has 9 hours of cutscenes. 9!!!

DanielSank

@alarge Cool. Looks like I'm starting to learn something.

Mostafa

@heather Take a look at this .

DanielSank

Avertisement: This week in my weekly featured post chat room: Connecting statistical ensembles to decoherence.

Yo, @alarge, suppose I want to ask what happens if I start with white noise (i.e. Wiener process), filter it to some maximum bandwidth, and then integrate. How would I represent and calculate the resulting distribution?

0celo7

haha you said Wiener [this message now 53% more awesome - ACM]

Q: Compute the curvature of a bent stack of paper

Cross-posted at Mathematica.SE. My goal is to link the curvature of a bent stack of paper in a wind tunnel to its bending modulus $B$, knowing all the other physical properties. To this end, I would like to reproduce the numerical simulation in P. Buchak, C. Eloy and P. M. Reis, Phys. Rev. Let...

is that off-topic?

DanielSank

16:14

@0celo7 Should I flag that?

0celo7

@DanielSank Go for it

DanielSank

@0celo7 U sure, bro?

0celo7

you won't do it

ACuriousMind

It should actually be Wiener in both cases :P

DanielSank

@ACuriousMind Use your mod powers for awesome.

0celo7

16:15

@ACuriousMind I thought so, but I figured the PhD in Physics knew how to spell the guy's name.

DanielSank

@0celo7 Why would a PhD physicist use brain space/energy for spelling?

0celo7

Because the guy's work is used in your field and you'd like to spell his name correctly

DanielSank

I need all that space to learn stochastic processes.

@0celo7 Wiener did not work in superconducting qubits, bro.

Mostafa

@0celo7 Why capitalize physics?

0celo7

Probably not enough space available...

DanielSank

16:17

@Mostafa He's a n00b.

0celo7

@Mostafa Proper noun

DanielSank

@0celo7 Hmmm, I think that's actually offensive under ACM's definition.

Feb 24 at 1:13, by DanielSank

Orthography may be hard but it's also rather important.

DanielSank

Pretty sure he thinks you should be punished.

0celo7

@DanielSank but his work is applied to noise analysis

Emilio Pisanty

16:17

@DanielSank you still need to spell people's names correctly

0celo7

@ACuriousMind can punish me all he wants <3

DanielSank

Wow, everyone got a pitchfork and is chasing me...

0celo7

^probably going to get suspended for that

DanielSank

@0celo7 Nah, that wasn't offensive. Implying that I'm unable to learn stochastic processes was offensive.

Mostafa

@NeilCoffey Sure, if it's the first word of a sentence, or if a sadistic parent names their child Physics :-) — DanielSank Feb 24 at 1:12

@2017 Correct.

0celo7

@DanielSank It wasn't directed at you

ACuriousMind

::slowly backs away::

DanielSank

heheheh

0celo7

@ACuriousMind :)

Emilio Pisanty

@DanielSank see it as a particular instance of "people get annoyed when the American can't be bothered to spell and/or pronounce correctly in other languages" if you will

he said, adding fuel to the fire

DanielSank

16:19

@EmilioPisanty Oh give me a f------ break as if this is an "American" issue.

0celo7

It is an American issue.

Because Americans pronounce ie and ei backwards.

It's hard to keep track if you're bilingual.

2017

@DanielSank Sarcasm. :)

Emilio Pisanty

@DanielSank substitute for "Native English speaker" if you want to

DanielSank

You know what's absolutely hilarious, @EmilioPisanty? In the USA, we like foreign accents. We find them interesting and charming. However, if an American speaks another language with an accent, they are universally considered to be making too little effort or some such thing. Now you tell me, what does that say about the people involved?

0celo7

That Americans have shitty accents when speaking other languages?

DanielSank

16:20

My main point here is that folks coming to the USA with accents aren't harangued about it the way Americans are harangued about their accents in other languages. Why is that?

0celo7

@DanielSank Perhaps English with an accent is more pleasant than [insert other language] with an accent.

DanielSank

@0celo7 Indeed, but why?

Emilio Pisanty

@DanielSank please don't feel discriminated against. I make plenty of fun of Spanish/French/German/whatever people speaking English with strong accents.

DanielSank

@EmilioPisanty Hmph

Emilio Pisanty

It's a more particular point about the pronunciation of foreign names, particularly in science

as an example, one pet peeve is 'Hermite polynomials'

0celo7

16:22

Her-might?

Is that wrong?

Emilio Pisanty

@0celo7 yes

DanielSank

@EmilioPisanty orly? How do you feel about the fact that Spanish speakers completely mispronounce "London", replacing it with "Londres"?

0celo7

@DanielSank Cologne

AccidentalFourierTransform

@ACuriousMind that was fast o.O

0celo7

What did ACM do??

ACuriousMind

16:23

@AccidentalFourierTransform ::blows steam off dupe gun::

DanielSank

Or how about the fact that I say "China" where I should say "tsong guo da loo"?

@ACuriousMind nice

Emilio Pisanty

@DanielSank that's not "mispronounce". If you're speaking a different language and a place has a specific name in the separate language, that's way different.

0celo7

0celo7

16:24

@EmilioPisanty How do you say it (Hermite)?

DanielSank

@EmilioPisanty Ok but now you're cornered. English doesn't have a language authority. We consider whatever sees common usage as correct. If a lot of people, even in a particular city, pronounce something a particular way, we generally consider it "correct", whatever that even means.

AccidentalFourierTransform

that has to be some kind of record actually

Mostafa

Donald Trump Says "China"

►

Emilio Pisanty

@DanielSank placenames and people's names are nothing alike

Mostafa

@DanielSank Because Americans are used to non-native speakers; no other language has so many non-native speakers similar to American English and people find foreigners' accent very unusual.

DanielSank

16:25

Obviously, language is a utility and what matters is whether people can communicate. If you sound different than the majority of people around you, you've got an issue (not necessarily a problem).

ACuriousMind

@AccidentalFourierTransform 35 secs according to the precise time stamps :)

AccidentalFourierTransform

@Mostafa china china china, I have to have my china, china because china

ACuriousMind

Alas, no hall of fame for that

DanielSank

@Mostafa Indeed. But see this is what bugs me. I can have a conversation with French guy who has a super thick accent in English. I will not correct him and I'll make an effort to understand. Then if we speak French, and I have a thick accent, I'm considered "that American who can't speak French". Its pretty silly.

(For the record I don't care about this too much. I'm just enjoying some debate before work)

Of course, if the French person is a friend, then I'll correct him as appropriate so he/she can learn.

AccidentalFourierTransform

is "xkcd" on the starboard misspelled on purpose?

is it some kind of reference that I dont get?

DanielSank

16:28

Another example of this: French person goes to New York. Their English isn't great. They talk to someone on the street. If that someone knows French, they'll delight in using it with the visitor.

Interestingly, I experienced something similar in Japan: people on the street seemed to enjoy practicing English with me.

So what's the deal in Germany @ACuriousMind? Folks like practicing English or are English speakers on the street felt to be an annoyance, or something in between?

Emilio Pisanty

@DanielSank Germany varies a lot in that respect, depending on how 'urban' a place you're in

AccidentalFourierTransform

@DanielSank hell I know. Im not @ACuriousMind

@EmilioPisanty Makes sense.

Emilio Pisanty

@DanielSank but frankly, my experience in Berlin was quite the opposite

AccidentalFourierTransform

@ACuriousMind please fix it. For us people with a slight OCD :-P

otherwise, Ill have to leave the room

I just cant.

Emilio Pisanty

as in: foreigner starts speaking German, then German person switches to English

ACuriousMind

@DanielSank Many Germans will switch to English if they think you're better at English than German.

DanielSank

@EmilioPisanty Ugh.

Emilio Pisanty

16:32

practicing English is not really seen as a necessity

DanielSank

Ah.

Emilio Pisanty

@DanielSank yeah, I was generally annoyed by it

DanielSank

@ACuriousMind With less weight given to the native's English ability?

@EmilioPisanty It's a balance. I suppose folks might to that as a favor!

Emilio Pisanty

@DanielSank people just want to get the conversation flowing in the quickest way

if they feel their English is better than your German, they'll switch to that

DanielSank

I can understand that. I suppose it's best to be clear. If it's a friend, perhaps say you want to try German.

Emilio Pisanty

16:34

and unless your German is really good, their English is probably better

it does mean, though, that practicing German is really hard

AccidentalFourierTransform

I sometimes switch to a language neither of us understands

Emilio Pisanty

pretty much the only folks that'll answer back in German are Turkish

Emilio Pisanty

@0celo7 as in

AccidentalFourierTransform

non-fibré fibré

Emilio Pisanty

Chirp

A chirp is a signal in which the frequency increases (up-chirp) or decreases (down-chirp) with time. In some sources, the term chirp is used interchangeably with sweep signal. It is commonly used in sonar and radar, but has other applications, such as in spread-spectrum communications. In spread-spectrum usage, surface acoustic wave (SAW) devices such as reflective array compressors (RACs) are often used to generate and demodulate the chirped signals. In optics, ultrashort laser pulses also exhibit chirp, which, in optical transmission systems, interacts with the dispersion properties of th...

Slereah

@0celo7 a bundle without a typical fiber

I dunno of any examples, though

DanielSank

What's particularly funny is that the "official Russian" words sound like they're intentionally trying to not be English.

0celo7

16:50

@Slereah what?

Emilio Pisanty

@Slereah is there such a thing as a nun-fiber bundle?

Slereah

I recall seeing that they existed

0celo7

What's a bundle if not a locally trivial thingie

Slereah

I didn't investigate much though

Well, same as usual

DanielSank

For example, the common-use word in Russian for "computer" is "kom-pyoo-ter", i.e. roughly the same as the English word.

That's called a fibered manifold

Slereah

"For example, one can consider a bundle π: E→ B with E and B sets. It is no longer true that the preimages π − 1(x) must all look alike, unlike fiber bundles where the fibers must all be isomorphic (in the case of vector bundles) and homeomorphic."

DanielSank

However, there is actually some other official and needlessly complex word that can be thought of as "computing machine" or some such thing. Nobody uses it.

DanielSank

At least, that's how I remember her explaining it.

Slereah

Bundle (mathematics)

In mathematics, a bundle is a generalization of a fiber bundle dropping the condition of a local product structure. The requirement of a local product structure rests on the bundle having a topology. Without this requirement, more general objects can be considered bundles. For example, one can consider a bundle π: E→ B with E and B sets. It is no longer true that the preimages π − 1(x) must all look alike, unlike fiber bundles where the fibers must all be isomorphic (in the case of vector bundles) and homeomorphic. == Definition == A bundle is a triple (E, p, B) where E, B are sets and p:E→B a...

Some examples

DanielSank

@EmilioPisanty Yeah, I hear native Chinese speakers use English for technical words all the time.

...while conversing in Chinese.

A past post-doc in our group expressed concern that he would have trouble getting a professorship in China because he couldn't talk physics in Chinese!

Yashas Samaga

The plank length is derived using dimensional analysis?

Mostafa

The situation for translation in STEM fields is not nearly as serious as in philosophy and social sciences.

Slereah

you can derive the planck length in a variety of ways

Originally it was done using dimensional analysis, yes

since it was before general relativity

AccidentalFourierTransform

16:56

it is ultimately a definition, so any "derivation" is actually a "motivation".

ACuriousMind

^

Yashas Samaga

I am going to have a hard time digesting the fact that Max Planck used dimensional analysis to obtain that famous constant.

Slereah

Well, why not

He did it in like 1908 or something

He didn't have quantum gravity on his mind

1899, even

AccidentalFourierTransform

well, using dimensional analysis, $1908\sim 1899$

Yashas Samaga

@ACuriousMind can you edit my comment and fix the typo? I wrote "plank" instead of "Planck"

Emilio Pisanty

16:58

@YashasSamaga who said Planck invented the Planck length?

Slereah

he did

ACuriousMind

@EmilioPisanty From Wiki: "It is a base unit in the system of Planck units, developed by physicist Max Planck. "

Slereah

It was one of his proposal for a natural system of units

ACuriousMind

@YashasSamaga Live with it, I'm not the official typo fixer :P

Slereah

It was unrelated to any physical idea

Yashas Samaga

16:59

Aw.

Emilio Pisanty

If nothing else, the "famous constant" is not the Planck length

0celo7

@ACuriousMind ...

ACuriousMind

@0celo7 !!!

Emilio Pisanty

the Planck constant itself is $\hbar$ (or $h$ if you prefer) and it wasn't derived via dimensional analysis

0celo7

@ACuriousMind ???
