Technically if u wanna be so strict about it, there are so many old languages that are similarly hard

#

Arabic is just still in use

#

What do you mean?

#

While many changed a lot

#

Sanskrit and a lot Indo European languages in their old form are also hard

velvet dagger
#

Sure, nobody that I know of said that Arabic is the hardest language in the world lol

neat lintel
#

Too stupid for the always serious grown ups

#

Imagine not liking fanbase

#

Such a based term

#

I am gonna use it a lot

#

English fanbase, German Fanbase

velvet dagger
#

But for instance, for the most part non-English speakers have an easier time speaking English than non-Arabic speakers have learning Arabic

neat lintel
#

Ah

velvet dagger
#

And this is true after you normalize for the obvious shit

#

Like "Oh do you already know a romance or germanic language?"

neat lintel
#

I'm a native Arabic speaker and it is a lot easier to articulate myself in English than it is Arabic

#

I mean, it doesn't make any sense to call languages the hardest

#

It's all relative

neat lintel
#

Sloth disagreed 😦

velvet dagger
#

What I said was

#

Trying to pretend like there's nothing you can say other than shrug and mutter "depends on what you know already" is wrong

neat lintel
#

German is the Minecraft of languages

#

English was rather easy for me to learn because it's grammar is almost a subset of the grammar of my native language, the words roughly similar, especially technical terms etc...

#

U make ur own words up

velvet dagger
#

Look here

neat lintel
#

but I'm sure if I were Chinese, it would be really difficult

velvet dagger
#

I literally agreed that prior factors influence how easy/hard languages are to pick up

#

So there's no linear ordering of difficulty

neat lintel
#

I'd like to be proven wrong about the fact that there is an Arabic learner who speaks and writes in the same way a native speaker would. I just have not met or seen anyone like that in my 20 years of living. It would actually give me a lot of hope if I ever meet someone like that, but alas

#

Agreeeed

#

I can bullshit so much shit in English compared to Arabic

neat lintel
# velvet dagger Look here

If u give people enough criterias and unrelated categories people will always try to force comparison, isn't everything comparable to everything ?

neat lintel
velvet dagger
#

That sentence says nothing

neat lintel
#

I think it's very rare in general

#

It says that this idea of categorising hard and easy always seems kinda bad

#

We force unnecessarily

neat lintel
#

No, it's German

#

Oh that's very interesting

velvet dagger
#

I mean nobody forces anything, when I say, for instance, that English tends to be easier for people to pick up

neat lintel
#

That's understandable too, German is very difficult in its own right

velvet dagger
#

I am literally repeating what people who had to pick up English and some other language tend to say about it

neat lintel
#

I think even with English, it's quite rare that people actually have native proficiency

neat lintel
velvet dagger
#

They're not forcing comparison they're literally musing about the experiences they had in their life

#

"That's cus they hear it more often"

Do you know the person I'm talking about?

neat lintel
#

Making it experience dependent and more individual

velvet dagger
#

Because guess what

neat lintel
#

Many people claim that they have it, but they underestimate how much reading a native English speaker does, leading to them knowing way more words that they, as a learner, may have never seen before.

velvet dagger
#

My dad learned German first lmfao

neat lintel
#

That's why I always preach teaching your toddlers more than one language at birth. It is proven that children CAN learn more than one language and it is so so much faster than learning one as an adult

velvet dagger
#

Not as in, he's native German speaker

#

He's native Berber speaker, from an Arab speaking country

#

And he finds English easier than Arabic, German, French, and Berber

#

You're just talking out of your ass now

neat lintel
# velvet dagger My dad learned German first lmfao

See, cus he saw more German than English
Meaning it was easy for him to understand German cus he came across it more often, making it a personal criteria for his hard and his easy
But u can't make universal criteria out of it

neat lintel

#

Duck I think the part of the reason you're so hesitant here is that you're apparently finding English too hard to actually effectively here. That or you're just making up blatant nonsense in order to continue being right

#

I literlaly already said, yes there is no linear ordering

#

But pretending like all one can do is just throw your hands up and shrug

#

Goes against the experience of many people who learn multiple languages

#

And it seems like the only thing you can do to deny that is (a) make things up, or (b) vaguely mutter "B... B... But personal experiences.........."

neat lintel
#

I can speak multiple languages too, but I still think if u wanna learn a language, it is only dependent on personal experience and language y already k

velvet dagger
#

"only dependent" yeah turns out you're very likely wrong

#

And you're just doubling down on nothing at this point

#

Anyway this conversation has exhausted its entertainment/learning value for me

neat lintel
#

I think it definitely needs some preparation. If the unlikely time comes where I get children, I will try to pass them 4 of my languages or so after a lot of heavy consultation. I think that would help them so much in life if done right tbh

velvet dagger
#

So let's agree to disagree

neat lintel
velvet dagger
#

Lixera: yeah so what I've heard is that if you teach a child multiple languages, you're supposed to have a parent speak each

silver meteor
#

dami?

velvet dagger
#

Yeah my parents tried teaching me 4 languages when I was a baby

neat lintel
silver meteor
#

neat lintel
velvet dagger
#

English because ofc, Berber because that's my ethnic language, Arabic because Islam and because we're from Morocco, and French because Morocco

neat lintel
velvet dagger
#

Okay I said that weirdly but

#

I was born/raised in America

#

And from a Berber Moroccan family

neat lintel
#

there are probably a lot of technicalities that you need to be aware of before attempting such an adventure

#

Idk

#

Children scare me

#

So much responsibility

velvet dagger
#

And yeah so what I heard was that the correct way is to have a parent speak one language and another parent speak the other

#

My family didn't know this. We didn't just have my parents, my aunt also lived with us and my grandmother was around a lot

#

Turns out they just mixed a lot

#

In Morocco people very often alternate languages, including within a single sentence

neat lintel
#

A child

velvet dagger
#

Mostly Arabic and French for people in Morocco, but because my family is Berber now we throw that in the mix

#

At the time my dad didn't know Arabic super well, but he was really good in Berber, French, and English (also German but that didn't matter for me lol)

#

My mom and aunt learned half their Berber from talking to my dad so much, but were both very good at Arabic and French, and were picking up English

#

Grandmother knew Arabic and Berber mostly

#

So I think everyone just kinda spoke to me the way they did

#

And I just got confused

#

So yeah I went to the doctor once at like, 2.5-3 years old

#

And the doctor was like wtf his speaking level is that of a 6 month old. He doesn't know anything beyond like, calling you guys

#

Thought I was deaf

#

Or mentally handicapped

#

And there was a bunch of merry go round before someone thought to ask how my family taught me

#

And realized that it doesn't work and that's why I didn't pick up anything

#

My off the cuff guess would be "somewhat"

#

Like, I figure I'm better than the average person but nothing special. What are you thinking?

devout nacelle
#

I didn't talk besides making some sounds at all till that age I think

velvet dagger
#

Maybe that's why I'm good at figuring out what people mean on this server when they express their points badly 😛

#

Nah but yeah maybe, I never thought about that though

#

Lmfao. Apparently when I finally started picking up English I started right away with sentences

#

Since I kinda already knew what was going on at some level I just got confused since there was no consistency

#

With some kids it's like, either outside the house they speak English and inside they speak either Arabic or Berber

#

Or maybe on a certain day of the week, or it depends on the parent

#

But somehow they know "when to say what"

#

And I didn't. But once my parents zoomed in hard on English

Followed by like stats or calc or some other thing

#

Many students also didn't take precalc at all, instead taking "Advanced Functions and Mathematics"

#

But most students in the precalc course were on the "accelerated track" and so were juniors who took calc the next year

i write so many shti things in testrs

#

lim ak = lim bk --> ak = bk

#

if i were to reread this i would have caught it

neat lintel
#

my strat is to always do the test quickly one time and skipping hard problems and doing whats easy to get the most points, then doing any problems i missed.
also while taking the test i put little stars to signify how unsure i am of my answer
no star means im confident
1 star means i want to go back over it, so on and so fourth.
and so then i go back over it doing all the problems that im most unsure about, and by the end if i have time im doing the problems i was most confident about and ensuring each step is justified.
then if i have EVEN more time i just keep doing the test over and over till time

#

professors HATE me i bet but i consistently top score using this method. if youre given time use it 🔫

#

also do practice problems before the test if you can + answering questions in this server can help you find things you wouldnt have thought to study

haughty lintel

math is an interesting subject because of that, because if you get a bachelors in say biology or chemistry, you know a lotta chemistry or biology. But with a bachelors in mathematics, you still barely have scratched the surface

What does it mean if two sets are isometric?

#

If the points in them have the same distance?

deep mango
#

umm

deep mango
#

there's a function from one to the other which respects distances

#

so if x and y are some distance apart

fading pulsar
#

Ok maybe I can give more context, it's part of this question

image.png
#

Seems like obviously not isometric

deep mango
#

then f(x) and f(y) are the same distance apart

fading pulsar
#

but yes homeomorphic

deep mango
#

yeah, your intuition is correct

#

can you prove it?

fading pulsar
#

I mean it's just a counterexample for isometric though

#

and 1/n is the homeomorphism

deep mango
#

exactly

#

it's pretty hard for subsets of R to be isometric usually

fading pulsar
#

too many points to account for?

deep mango
#

more like, too little space for them to bend and twist

#

most of the time you can only translate them and reflect them

fading pulsar
#

so it would be easier for function spaces?

#

I have a question to show an isometric embedding from X to B(X)

deep mango
#

even just in R^2 it's easier. a line segment and an arc in R^2 can be isometric

#

well

#

sorta

static loom
fading pulsar
#

Can someone explain the notation here?

#

Is f(x)(y) a typo for f(x,y)?

deep mango
#

f is a function from X to functions from X to R

#

so f(x) gives you a function from X to R

#

and then you evaluate that function at y

ok ty makes sense

Pretty much every subject in Algebra 1

#

do you know about completing the square?

onyx vessel
#

Yes

#

personally i think i remember things better if i understand the details of how they work

#

but also there are study methods that they say help psychologically

#

like supposedly writing down notes helps memory better than typing? ive heard

neat lintel
#

I don't memorize anything math related, never have. It makes me slower on tests but if you understand it, then each time you need to use it, you can figure it out again. (also each time it gets faster). And yes, I still don't know the quadratic equation 😄

On the topic of actual advice, it has been shown that the act of writing things down does help memories form better.
But I think you'll be better off in the long run to not memorize anything. Then, when you face something new, but similar to a problem you've understood before, I think you'll have a better chance than others who are looking for an equation to "plug and chug" (as we used to call it)

Bruh these new helpers

#

I mean they like to give away the whole answer

#

Theyre like here you go just take it and shut the channel off

#

The only reason I love the help system here is that the rules mention, "if you are providing help to others, try your best to explain and elaborate instead of simply giving away the answer"

I dont have access to that

#

Helpers in help channel?

peak tide
split pawn
#

Maybe its for Helpful.

#

I see

tiny saddle
split pawn
#

I dont have Helpful

#

Cause

tiny saddle
#

Only those with the helpful role can

peak tide
#

oh, Helpers doesn't give you access? i didn't know

split pawn
#

Whenever Im free I help people around

tiny saddle
#

And mods and administration ofc

split pawn
#

But I cant stay

#

like

#

online all the time to help people to get that role

#

Im a student whos got to study and do other stuff too 🙂

#

Yeah just see the forum channels

#

Forum posts I mean

peak tide
#

@split pawn if there's a specific person who's doing it routinely you may want to mention it in modmail.. they can decide what to do, if anything

split pawn
#

Esp new members

#

Which implies

#

They dont read the rules

#

They just

#

Put in answers

#

The help channels are better because I see that Helpful people are regularly active there

#

And

#

They wont let someone do that

#

Altho in forum posts, I dont see much of em around

peak tide
#

yea, i think only a subset of helpers are actually looking at the help forums

#

the mods themselves say the forums are a work in progress

#

but they are apparently also the future

split pawn
#

Haha like me

#

Forums are awesome

#

But kudos to the team who made the help system here

#

Its really neat tho

peak tide
#

i think both could coexist reasonably

#

help channels for relatively quick real time help with relatively simple questions

split pawn
#

Ive been a member since 2021, just that I left in between and have this Aug 22 date lol

peak tide
#

forums for harder problems that need specialized help maybe

split pawn
#

I see...

#

Yeah they can coexist

peak tide
#

apparently the issue with the channels is that they don't scale well as the user base grows

split pawn
#

Well, advanced problems can be sent into respective Adv, Math channels

peak tide
#

due to discord limitations

split pawn
#

Theres a lotta math servers Im in and I dont help anywhere at all unless I feel like it

#

Because

#

Theyre like

#

Hey just gimme that answer and go do your work

peak tide
#

totally fair, no one should ever feel obligated to help, it's totally voluntary

split pawn
#

Yeah...

peak tide
#

and some users definitely expect to be spoon fed

split pawn
#

Yup yup.

#

Thats not my thing

#

Ill just like

#

Guide someone who needs help

#

And leave him to figure out the other steps

#

If I see he really doesnt get it

#

Then I may go. step by step

#

and still make them do some basic steps themselves

peak tide
#

yep

#

people learn better if they have to do at least some of the thinking themselves

#

they = we

split pawn
#

Yup

#

We all.

#

Its better to let ourselves analyse and progress through the steps onto the solution rather than getting that ready-made bunch of steps

#

Hes just gonna see 7.1 s and boom. There you have it.

#

(Its not my job to tell these people to actually have a look at the rules and not give away solutions like that, altho i told a few)

peak tide
split pawn
#

Haha, same

peak tide
#

i think there are enough helpers that if someone is doing this routinely they're eventually going to get schooled by one of the helpers who do consider it their job, and there are a few of those

that's if you're trying to change the world though, If you're doing it just for fun though then whatever but it's just going to be confusing for everyone else if it doesn't catch on and then you're going to have a spend a lot of time changing it

there are some non-standard operations which have their own notation like the vec() and diag() operators catThin4K first one takes a matrix and transforms it into one long vector and second one takes in a vector and transforms it into a diagonal matrix with entries on the diagonal equal to vector components

@rich ether @void tundra i honestly doubt discord makes a lot of money with nitro, especially considering they keep looking for new ways to monetize the platform

void tundra
#

not many people are subbed to nitro

#

so I agree with you

surreal sapphire
#

its also very clear to me that their priorities when it comes to development are wrong, not because the app is buggy but there are way bigger issue that will turn into a big problem any day now

#

the way discord makes money is via "command capital"

void tundra
#

yeah by having a shitton of users

surreal sapphire
#

they have a giant userbase and they can move it to do things either implicitly or explicitly

long matrix
#

im very unaware about this kind of thing

void tundra
#

when was the last time they had a cash injection tho

long matrix
#

i just assumed they were doing ok

surreal sapphire
#

controlling such a huge userbase is valuable anyway, but not directly in the monetary sense

void tundra
#

I heard tencent took a stake in them or something

surreal sapphire
#

this is is why musk bought twitter

#

twitter doesnt make money

#

its valuable because you can "command" such a huge userbase

#

alternatively it only has to seem valuable to attract investors

long matrix
#

u cant directly control

#

so command ?

surreal sapphire
#

and you can collect a ton of data that might or might not be valuable in the future

void tundra
#

didn't twitter lose a shitton of ad $

surreal sapphire
#

not directly

#

but you shouldnt underestimate it

#

We train the algorithm to train us to serve the interests of its owners. The more we do this, the faster the algorithm learns how to help us train it to command us. As a result, the owners of this algorithmic cloud-based command capital deserve a term to distinguish them from traditional capitalists.

void tundra
#

where's that from

surreal sapphire
#

Second, the same algorithms that guide our purchases also have the capacity surreptitiously to command us directly to produce new command capital for the cloudalists. We do this every time we post photos on Instagram, write tweets, offer reviews on Amazon books, or simply move around town so that our phones contribute congestion data to Google Maps.

void tundra
#

TIL "command capital"

surreal sapphire
#

someone could buy discord and inject personalized ads at any point

#

and even without that, the giant heaps of data could (or already are) useful to train whatever machine learning model you have

#

you could also push an agenda to people via discord and they wouldnt even notice

#

this is happening on facebook for example

What announcement

fading pulsar
#

How do I get better at telling what spaces are separable (or not)?

#

i.e. bounded uniformly continuous functions on R, or something like all continuous functions that have limits at infinity

deep mango
#

if the thing you're dealing with is defined in terms of spaces that are separable, try to use countable dense subsets of those spaces to construct a countable dense subset of the larger space

fading pulsar
#

ok yea that makes sense

#

thanks

deep mango
#

in the other direction, you can try to find an uncountable subset of points where are all far from each other

fading pulsar
#

oh yea so just like the proof for l infinity not separable

deep mango
#

that doesn't always imply separable

#

yeah

#

like, this subset exists for all the lp spaces

#

but it's a useful place to start for showing a space is nonseparable, even if it doesn't imply it directly

#

o wait

#

yes if its uncountable it does show its nonseparable

#

nevermind

#

i was thinking countable

fading pulsar
#

why do we care about holder continuity

#

was just mentioned as a side note to a homework problem

#

"Note: This fact justifies why one only considers H ̈older exponents up to 1. (Recall that f is H ̈older
continuous with exponent α if there is C such that |f (x) − f (y)| ≤ C|x − y|α for all x, y.)"

fading pulsar
deep mango
#

It shows up in a lot of places: PDEs often have solutions which we can show are not just continuous but are holder continuous, in probability brownian motion ends up being nondifferentiable but holder continous (with alpha < 1/2), holder continuity has an interesting meaning in terms of fourier series as well

#

trying to think of more

velvet dagger
#

Wait hmm so

fading pulsar
#

ok so maybe something i might see in a later class

deep mango
#

fractals oftentimes end up having properties of holder continuity instead of differentiability, like weierstrass's nowhere differentiable function or the koch snowflake

velvet dagger
#

You know when they say you're in C^{2.5} it means C^2 + second derivative is 1/2-Holder continuous?

deep mango
#

if you learn more analysis, youll end up finding out that holder continuity is a really good way of saying "this function has a fraction of a derivative" and that that notion matches up well with the other notions we have of fractional derivatives (sobolev spaces, fourier transform derivatives)

deep mango
velvet dagger
#

And how there's also fractional Sobolev spaces which I think can be defined in terms of Fourier? I'm guessing that oh differentiation multiplies by x so we want the Fourier transform to be something you can multiply by x^{1/2} and still be in L^whatever

#

Do these ideas coincide?

deep mango
#

(i think most people would say C^{2, 1/2} to avoid the issue of C^{k, 1} not being the same as C^{k+1})

deep mango
#

so

#

they're not exactly the same

#

but in some sense these are like the sobolev spaces for p = infinity

#

for example, W^{1, infinity} (the space of functions whose weak derivative is L^infinity) is just the space of Lipschitz functions

#

but idk how people define W^{s, infinity} for s fractional since fourier transform of L^infinity is not good

velvet dagger
#

Oh that's prob like, "MVT"

#

Or something

deep mango
#

yeah

#

maybe you can do it on bounded domains

velvet dagger
deep mango
#

like on periodic interval, L^infinity is a subset of L^2 so fourier series are still L^2. but they don't converge uniformly

#

so idk

velvet dagger
#

Rest in rip

deep mango
#

ok it's just holder continuity.

image.png
#

if you throw in p = infinity there

velvet dagger
#

So these are "basically" the same way of seeing fractional derivatives, that's good

deep mango
#

yes

#

well im lost on your first line

#

in plain words, what are you defining that integral to be

#

where does the text break

woven whale
#

a \neq R ideal

#

(0) \neq r \subseteq a subring

tropic talon
#

can someone help me decode something?

#

this channel is occupied; sully

#

i paid for it

woven whale
#

in general we have $\oint = 0$ for any char 0 field

fathom swallowBOT
woven whale
#

because you can embed Z into it

long matrix
#

im cryin, first tell me what that integral is

woven whale
#

I have no idea either 😭

long matrix
#

ok whats the context

#

where is this stuff from

woven whale
#

I saw it written in the stars

long matrix
#

huh

#

ok so f is a ring endomorphism

#

We take the union over all proper ideals of (the intersection of the image of non-trivial subrings of the ideal)

long matrix
#

i barely even have intuition for subrings in general ring theory for starters

#

Looks like algebra

#

I can't do that

long matrix
#

theres some integral signs

#

arent u drooling

#

from how its notated looks like topological rings?

#

if thats a thing

#

measure rings?

#

I literally have no idea

#

But the integrals dont have dx's

long matrix
#

isnt that like usual
