ultimate form of exclusivity in a relationship isnt a strong basis

[velvet dagger]

You can ask why this differentiates between gay couples and straight couples but not polygamy and monogamy. There's probably a case to be made that it should allow for the latter (I'm not a legal expert to say), but my first guess as to why it might not is that if someone is gay, marriage as an institution discriminates against this person relative to straight people, but being "a polyamorous person" is perhaps seen less as a sexual orientation thing and more of a moral preference thing, so it's harder to identify it as a category of person who can be discriminated against?

Again I'm just kinda reasoning about shit I have no real experience in which is massive Dunning Kruger but

I've got a very good track record about being at least somewhat accurate when I Dunning Kruger so I'm willing to gamble and say this out loud

[light needle]

polyamorous isnt really a "moral" preference

not allowing poly marraiges is kinda dumb

[velvet dagger]

Oh I agree

[neat lintel]

no

[velvet dagger]

My point is more like

[neat lintel]

allowing marrige without strong basis is dumb

[velvet dagger]

People might think about polyamorous relationships in the sense of

"Are you okay with the idea of multiple partners" rather than a matter of sexual attraction

[neat lintel]

so allowing non religious marrige is mindbogglijg to me

[velvet dagger]

Mahael so

[neat lintel]

i get your point about realityy

[velvet dagger]

The thing is you can worry long term about whether, in 500 years, you can destroy the idea of marriage as being a legal or societal phenomenon rather than a purely religious one

The ideal I imagine you have is that members of a church/mosque/etc would marry their members according to their religious rules

[neat lintel]

well its already destroyed is my point

[velvet dagger]

And that it has no legal anything to it

But that's simply not how it is

[sick burrow]

Wait polyamory isn't "are you ok with multiple partners"?

[neat lintel]

it isnt?

[velvet dagger]

I really hope you're not that naive lol, feels like you're doubling down on a position you know is indefensible because you've been backed into a corner and haven't accepted fate rather than actually believing that

[sick burrow]

Is that not what dami was saying

Or am I dumb

[velvet dagger]

Literally married couples have tax benefits

[neat lintel]

yes

[velvet dagger]

Inheritance is easier

etc

The institution of marriage is alive and well

Regardless of whether you believe it's correct or incorrect

[neat lintel]

but there is no strong basis is why in saying its destroyed

[sick burrow]

Dami savage

[velvet dagger]

You need to distinguish between is vs ought

There's no strong basis so you think it ought to be destroyed

But while it's literally a thing that influences millions of lives on a daily basis

[cold needle]

🙈

[neat lintel]

yes clearly it exists

[velvet dagger]

Doesn't feel very destroyed

Like idk... let me come up with a stretched example to make this point

Best thing I can think of offhand is kinda sketch is the thing. Let's say someone believes that citizenship of a country shouldn't be a concept which exists

[blazing pawn]

Marriage as an institution is objectively not "destroyed" lol

[velvet dagger]

I'm not gonna get into the debate on whether that person is right or not

[blazing pawn]

It has a lot of important social and legal benefits

[velvet dagger]

But pretend someone doesn't believe citizenship as an idea should exist

Now imagine there's a country where the idea of citizenship is firmly entrenched

And imagine this country also denies citizenship to people of a certain type

You can be like oh the idea of citizenship in general is wrong, all those residing in a country should have similar privileges

[blazing pawn]

also its just important to a lot of people and whether or not you agree doesnt change the fact that its significant culturally

[velvet dagger]

And as a result, eh why bother helping people who are being denied citizenship and are being harmed every day because of this

When really we should be trashing citizenship as a notion entirely

Like okay cute ideals are cute but

Deal with destroying citizenship over the 500 years it will take to destroy that idea

And if you can provide citizenship for the people who deserve it literally tomorrow

And spare them 500 years of relative suffering

Do that rather than have your head in the clouds

[neat lintel]

i meant marrige is destroyed in the sense that for people who practice it currently it is so very divorced from its original intentions that is might as well not be considered marriage

[velvet dagger]

The case that I imagine you have in the back of your mind is that doing so somehow validates the idea you're trying to destroy and maybe prevents the long term goal? But I don't think it does

[blazing pawn]

I mean ok so what then lol

[velvet dagger]

You can say marriage as a thing that's strictly church-centric rather than government-enforced might be destroyed

But then government-enforced marriage as a 2000s phenomenon isn't destroyed

[light needle]

concepts evolve over time

[velvet dagger]

Now confront this reality appropriately

[cold needle]

Thanksgiving is an excuse to buy things 😼 .

im kidding around but

[velvet dagger]

Christmas might be a better example

[cold needle]

yeah

[neat lintel]

sorta my point though

[velvet dagger]

Tbh I wouldn't be surprised if like

Churches eventually come around and are like

Christmas is now no longer a valid Christian holiday

Because tbh it isn't lol

And it becomes a strictly American consumer thing lmfao

[blazing pawn]

Well technically it was pagan from the start anyway

[velvet dagger]

Yeah

[cold needle]

o

[light needle]

not just american dami

smh

[velvet dagger]

Idk how crazy other countries go on Christmas lol

But yeah that's the thing like

I'm pretty sure literally every priest in this country is fucking it up

By continuing to allow Christmas

[light needle]

ok im trying to remember childhood memories

i was in maylasia one of my christmases

when i was v young

[neat lintel]

justifications for allowence of gay marrige and polyamorous marrige is based on addressing religious stances, but the concept is divorced from religion, so why do we still call it such and require preists to complete ceremonies

[light needle]

i think they celebrated christmas commercially

[velvet dagger]

The case for allowing gay marriage legally wasn't a religious one actually

Marriage is a technical legal term

[light needle]

altho i might be remembering like, new years

[velvet dagger]

And I'm pretty sure the legalization of gay marriage comes with literally zero mandates on religious institutions to back that up

[neat lintel]

what?

[sick burrow]

nM may I suggest you actually take some time to critically think over your opinions

[velvet dagger]

So you can have a gay couple that is legally married and is able to file taxes jointly, have inheritance benefits, etc

[sick burrow]

like it's not even that you're coming from a bad place

[velvet dagger]

But the church can be like

Nah gay marriage isn't a thing in this religion so we don't acknowledge this marriage

[sick burrow]

it just feels like you genuinely haven't though your position here through

[velvet dagger]

That's just allowed

[neat lintel]

i have? point to exactly where you see this

So then all arguments ive heard that are anti gay marrige are legal based? Yet I havent heard one argument that doesn’t incorporate religious aspects

i swear im being gaslit rn

[velvet dagger]

Anti yes

The point is this

Religion used to have a big role in society

So if a religion declared something to be immoral

It was made illegal, even in societies (e.g. America) which were technically secular

So now you have marriage as a thing

Which is done by churches

[blazing pawn]

The fact that people who dont support gay marriage do so on religious grounds doesnt mean that the people who do support gay marriage do so on religious grounds

[neat lintel]

thats my point

[sick burrow]

moth you changed your pfp and now I'm confused

[velvet dagger]

They decide to codify a notion of marriage in law which provides privileges to couples which are married in the religious sense

[neat lintel]

i never met anyone who was anti gay marrige for legal reasons

[velvet dagger]

So tax benefits, inheritance stuff, child stuff, etc

[neat lintel]

im being gaslit i swear it

[blazing pawn]

What are you even trying to argue then...

[velvet dagger]

You're not being gaslit you're confusing the causality here

The point is that marriage was made as a legal thing to mirror the religious one. But once it is created it provides legal benefits

[sick burrow]

you're not being gaslit

[neat lintel]

yes I know this

[velvet dagger]

So now people who were religious were like well our notion of marriage is man with woman

Gay people can't get married, they shouldn't even be having relationships because that's wrong

[neat lintel]

Yes…

[velvet dagger]

So they have no business being given these privileges

[sick burrow]

[velvet dagger]

Okay fast forward to today

[neat lintel]

yes those are the only anti gay arguments ive heard

[velvet dagger]

There is a legal phenomenon of marriage which has no need for a church but which provides concrete benefits

[blazing pawn]

This conversation is literally so pointless wtf are either of you trying to argue

[nimble shuttle]

[velvet dagger]

You now go and say well... Gay people are not being allowed to marry but there's no legal basis for this fact

It's an artifact of when people designed the law to have an incorrect level of reliance on religion

[nimble shuttle]

most productive #serious-discussion conversation

[velvet dagger]

You have two options. One option, which will not happen in your lifetime probably

Is to say let's just trash the legal idea of marriage

Married couples have no benefits, it's not an acknowledged concept in law. Churches can do whatever the fuck they want about marriages because they literally own that concept

Again this will not happen in your lifetime

The other option is you say well, right now the law discriminates against a class of people. Let's make it not do that. That can be done in the short term, and in fact has been done

[neat lintel]

Yes

You see the second option is what Im trying to focus on

[velvet dagger]

You've been practically arguing that there's no need to perform the second option when we should really be doing the first option

I think on some level we sorta agree on all the main points but you're just kinda confused about how the cause and effect is working here

[neat lintel]

ok

removed my incoming wall of text

[velvet dagger]

Like we could just take the word marriage and replace it with "civil union"

In law

[neat lintel]

yes

it exists

domestic unions

[velvet dagger]

And then it's a separate matter

Like alright do we think that people in some kind of union like this deserve e.g. tax benefits? Aka should this notion exist?

This is now independent of religion because we've abandoned the religiously loaded term

Second is, what should count as a valid union if we allow this to exist? So in this case yeah when we no longer make this religious there's no case against e.g. polyamory

Or we decide it shouldn't exist at all and everyone just screws whoever they want and the law simply doesn't care

[neat lintel]

i feel like my common sense isnt being respected but my only point in talking about marrige was to get to back to the point of racism being doomed and its advertisement. this entire conversation is a tangent about my confusion for why people still want marriage as a relationship goal even though the concept lost its strong basis, and the legal basis is somewhat strong imo

but not strong enough to be coherent

its not really relevant to my point I was trying to make in original conversation

[velvet dagger]

But okay, let's look at how we get from society as it is today to that hypothetical society which no longer puts weight on marriage? Turns out answer is, it'll take a long time, but in the meantime not being married comes with concrete disadvantages. So you're still incentivized by legal and societal forces

[velvet dagger]

Coherence of the concept doesn't really matter so much to people as benefit/harm, culturally and legally

Let's say you have some couple. They're not religious so they don't care about the OG concept

But they want to pay less in taxes

They want certain things that are just easier for married couples to be easier for them

[neat lintel]

ok

i left out something specific

im kind of talking about those who want marrige in the way that they want a house with kids and all the other aspects that are tied to the religious one, but dont have strong basis for it since they arent religious

[velvet dagger]

Cultural inertia

Well house with kids is not about the legal idea of marriage so much as a life desire

[neat lintel]

yea i find it detrimental

[velvet dagger]

Like yeah I'd like to live with my partner and have kids because I just enjoy that sorta thing

[neat lintel]

not really sure its worth having another conversation about though

but i believe if this is the case you need to think of marrige more critically and think of plans for it

[velvet dagger]

That's a reasonable desire to have for any individual couple. Should it be considered the gold standard for relationships? Probably not. But is it? Yeah. That is life. Maybe when I finish my psets I'll change that about society

Gimme a week or two

[neat lintel]

rip i cant continue this but ill say i disagree first sentence and agree second

[neat lintel]

also brb in 20 min maybe but what psets, in thought mods are all like 3rd year grad students or post docs or something

[untold sapphire]

dami is one of those unfortunate grad students who has psets

some grad schools have more coursework than others

or he's grading

[velvet dagger]

A pset to do

[humble solar]

Imagine having to do hw

[untold sapphire]

get gonked

[neat lintel]

wait i thought course work ended

after like 2nd sem

or 3rd

[untold sapphire]

like i said

different graduate schools vary

[velvet dagger]

Here it's like, there are one level of classes with regular psets (sometimes exams), and one level without. I could've honestly taken 3 classes with no homework but I thought this was worth taking. First half kinda was, second less so

[humble solar]

What a fool

I'm out here living my best life with no HW

[velvet dagger]

So is your face

[ancient flame]

what's the difference between an operator and a function

[mortal igloo]

They're the same type of thing, and calling something one or the other is a matter of convention

[ancient flame]

I see

so you could say that the integral is a sort of function?

so then $\int : \mbb{R} \to \mbb{R}$ makes sense?

[fathom swallow]

gmod

[mortal igloo]

There's multiple things wrong with that

[ancient flame]

like what

if you replace the integral symbol with f then there's nothing wrong

[mortal igloo]

If it's an indefinite integral, the input is a function and the output is an affine space of functions

[ancient flame]

oh

I see

[mortal igloo]

So maybe

$\int\colon C^0(\bR)\to C^0(\bR)/\ker\left(\frac d{dx}\right)$

[fathom swallow]

Icy001

[ancient flame]

idk what a kernel does lol

and what is C^0

[mortal igloo]

the /ker(d/dx) takes care of the +C

[ancient flame]

oh ok

[mortal igloo]

in complete rigor

[ancient flame]

what's the C^0

[mortal igloo]

continuous functions

[ancient flame]

oh okay

makes sense

tysm

[toxic schooner]

[leaden skiff]

what exaclty does the / mean?

not jsut in this context but in general

[mint patio]

kernel of a linear operator is the set of all vectors s.t operator(vector in set) = 0?

oh wait

That makes sense lmfao

[mint patio]

maybe they meant \ker and were just typing out the tex?

I know I type out Tex for words sometimes 🤣

[mint patio]

so here this is all constant functions

is that right?

[mortal igloo]

/ means modulo

[ancient flame]

the / is a "set minus"

oh

[mint patio]

OH

I TOTALLT

LOL

kms

[leaden skiff]

modulo?

[ancient flame]

wait it's not set minus?

[mint patio]

It is

[leaden skiff]

modulo a vector space?

[mortal igloo]

nope, it's modulo

Yep, a vector space modulo a subspace

exactly

[mint patio]

Wait what’s the difference

[mortal igloo]

Quotient of vector spaces!

[mint patio]

nvm I see it

[leaden skiff]

how exactly does that work?

[ancient flame]

then wouldn't it make sense for you to write mod instead of /

[leaden skiff]

maybe explain with the boring spaces like R^2 first pls?

[mortal igloo]

It's very standard notation

[ancient flame]

ew

[mortal igloo]

Yeah ok so e.g. let $V=\bR^2/{(x,x):x\in\bR}$

[fathom swallow]

Icy001

[mortal igloo]

This says that $V$ is basically pairs of real numbers but (x,y) is declared equal to (x',y') if x'-x = y'-y

[fathom swallow]

Icy001

[mortal igloo]

So the dimension of this vector space is actually 1 now

[ancient flame]

interesting

oh wait isn't set minus the \ symbol instead

[mortal igloo]

yes

[ancient flame]

ohhhh

alright

then it's not as vague

[mortal igloo]

V set minus proper nonempty subspace isn't a vector space anymore

[leaden skiff]

why x-x' = y-y'?

[mortal igloo]

Ok so the proper definition for a general quotient is

$V/W$ is the set of equivalence classes of elements in $V$ where two vectors $v,v'$ are equivalent if $v-v'\in W$

[fathom swallow]

Icy001

[mortal igloo]

Then we put an addition and scalar multiplication on it in the only way we can, to make it a vector space

[iron osprey]

note

this is just using the notion of quotient groups

where any vector space is an additive abelian group

so all subspaces are normal subgroups (by commutativity)

so if u know quotient groups or rings/modules u get all this stuff 4 free

[sick kite]

"Or at least, I think one of the ways alt-right groups are currently radicalizing people is by finding vulnerable white men and providing them with a semblance of a community while also telling them (insert often racist scapegoat group) are the problem" Is kinda what I meant. No need to through out claims about myself holding similar prejudices too like tf

like my communication ability isn't good

sry

[neat lintel]

lmao blocked

[uncut drum]

The questions I see in the math help channels have stepped up their level since I last checked them out

I don't see the 10th grade stuff

I saw a lot of more simple maths before but not as simple currently

[snow lintel]

i still see class 5 level stuff

[uncut drum]

I mean, it probably comes up

but right now I don't see it

before I'd always see simpler stuff as well

[hearty glacier]

does anyone have resources that i can read related to application of eigen functions

[primal crater]

lol

there's an entire field named quantum mechanics

[hearty glacier]

i have to give presentation on application of orthogonal and orthonormal set of function . i understood the concept but cant understand how its used in real life

on wiki of orthognal functions i saw this

[deep mango]

Maybe look at fourier analysis and how it's useful for solving PDEs.

[hearty glacier]

im trying to find out how orthogonal connects to eigen vectors and then show uses of eigen vector

[deep mango]

It's not hard to do a small thing on how eigenfunctions let you solve the heat equation using separation of variables.

[deep mango]

The connection is that when you have a symmetric operator, its eigenvectors / eigenfunctions are orthogonal. There's a really short cute argument to show this

If the operator is not symmetric then orthogonality isnt really related to eigenfunctions

[hearty glacier]

Motivating Question 1 There are probably twenty or thirty radio stations transmitting
in the Ann Arbor area. When I turn my radio to a particular station, how does it pick out
that signal from all the others?
Motivating Question 2 I want to store a sound file but I have a limited amount of
space to do so. What are the most important aspects of the sound to hold onto?
We’ll start by discussing Motivating Question 1, and move to discussing Motivating Question 2 later.

the pdf contains these applications

[deep mango]

Yeah those are both related to fourier analysis and the fourier eigenbasis.

[mint patio]

I wish S&S had pictures

excuse me

I've only heard of analytic continuation (from RH stuff lulw) but never knew what it was

Is that really it and how the fuck does that work

[leaden skiff]

is this true for real smooth functions?

[mint patio]

These are about holomorphic functions so I'm assuming generally no

[mint patio]

it can't be that easy right

[light needle]

it is, like the idea is that

lets say you have a holo function and you have defined it on some neighborhood

and you wanna holomorphically continue it to a bigger set

then this is unique

for the zeta function, what is done is that, ok we define it with series wheneve Re(s)>1

but then we can define it for everything else(except s=1) using the functional eqn

and gluing these together you get a holomorphic extension of the zeta defined as the series

so this is the unique way to define the zeta function from the series on C-{1}

[leaden skiff]

so wait, does this imply that if you know what a holomorphic function looks like, in any region, you know what it looks like everywhere?

[light needle]

kinda yeah

holomorphic is an extremely strong condition

[crystal stream]

for entire functions i think so yeah

[light needle]

this isnt distinct to the complex plane btw

this is true for all complex manifolds and holomorphic maps

if they agree on any open set (no matter how small) they are the same

[crystal stream]

funny how a simple system of pde's is such a strong condition

[mint patio]

Using the functional equation?

[untold sapphire]

there's a little bit more to it than this, it becomes more complex when you consider domains that aren't simply connected

[mint patio]

I'm assuming you have more restrictions when the domain isn't simply connected?

[mortal igloo]

No, when the domain isn't simply connected you can still do an analytic continuation but you get a multi-valued function and you have to change the domain to a Riemann surface to get a single-valued function again

If you like algebraic topology, analytic continuation gives you a holomorphic map from the universal cover of your complex manifold to the codomain

[sick burrow]

Oh interesting

Don't know anything about analytic continuation but the algtop perspective is cool

[dry tangle]

hi could maybe someone help me with a math problem?

if u guys have the time would apreciate that so much

Ngl Maths is so much more enjoyable when you aren't studying for exams

[fair mural]

i agree

[cinder roost]

Sincerely, I hate studying for exams, to the point where this is the last Mathematics module I'm going to be taking

meh

I'll learn it after I graduate

[toxic schooner]

Graduate HS?

[cinder roost]

No

When I've got my master's

[toxic schooner]

wowie

[wraith trail]

Lmao I gotta do exams to move up in my career

[cinder roost]

really

what kinda career is that?

[wraith trail]

Actuarial science

[cinder roost]

I've heard of doing exams to get certified and what not

Never knew that

[wraith trail]

7 exams to get first credential and another 3 for the second

[cinder roost]

ahh

[wraith trail]

Get raises after each and they pay for study time and materials

[surreal sapphire]

turns out to become an accredited professional you have to get accredited

[cinder roost]

tbh, I'm so glad programming jobs don't require accreditation

you can just be like here's my github ask me some questions

[surreal sapphire]

results will vary

[cinder roost]

Do you think that having additional accreditation helps in a programming type of career?

Anyway, is anyone interested in teaching me some calc 3

inb4 guiding me to help channels

[wraith trail]

What topic in calc 3?

[sick burrow]

[cinder roost]

well, there's something on fourier series (Q1) and then some of this stuff, appears to be Euler Lagrange equation (Q3)
inb4 I'm cheating this quiz is worth around 0.2%

[fair mural]

this is definitely not calculus 3

[cinder roost]

Then what is it?

[fair mural]

wait yeah it is

fourier stuff isn’t though

[cinder roost]

It's included in this module which they've changed over the years

"Mathematical Methods 3"

The thing is, it's become a little less Mathsy because half of Methods 2 was Python

So the modules at the university have kinda changed over the years

[wraith trail]

This ain’t stuff I really remember sorry

Been a good while

[fair mural]

i’m doing this right now and i don’t even understand half of it

[wraith trail]

I’m glad all I needed outta calc 3 was double integrals and jacobians

[fair mural]

wow that’s the one thing i don’t understand lol

[ancient flame]

sd7: says two things
quantum: "one thing"

[fair mural]

i basically just skipped calculus 3 after that since i need that knowledge for line and surface integrals

ok i meant double integrals

[wraith trail]

I needed double integrals for an exam based on probability

Same with jacobians but those were simple ones

[mortal igloo]

What's the probability distribution for the sum of two uniform random numbers in [0,1]? 😏

[simple laurel]

y'all are so smart idk what y'all are saying

[fair mural]

i sure don’t feel super smart

[wraith trail]

I’m def not super smart

[fair mural]

icy has a big brain though

[wraith trail]

Ya kinda questions like that

[sick burrow]

Wait how do you do that

[pale orchid]

something something triangle shape

[sick burrow]

Or wait is that double integration

[mortal igloo]

It's convolution 🙃

[pale orchid]

if the two vars are independent, it'd be the convolution of the distributions

yea

[wooden flax]

fancy stuff

[pale orchid]

which for two rectangular shapes is a triangle

[sick burrow]

What is convolution

[mortal igloo]

It's the question "how many ways are there for two dice to add to n" but continuously

[wraith trail]

^

[mortal igloo]

There's a formula too: for $f,g$ real-valued functions with compact support, $(f*g)(x)\coloneqq\int_{-\infty}^\infty f(t)g(x-t),dt$

hi, what job can i get besides insurance if i pursue a bsc in actuarial sci? i am looking for options

[leaden torrent]

risk

companies analyse risk for more reasons than just insurance

you could be a financial analyst examining whether branching out a company into a new industry is useful

the final decision rests with the higher-ups, but its the analyst's job to put together a lot of statistics and try and identify risks and cost-benefits and whatnot

and present their findings + recommendations to the decision makers

its ultimately just an office job with a bunch of number crunching no matter what you do - insurance, analysis, stock trading, whatever

very similar flavour

but it is a different position

[ancient flame]

that sounds absolutely horrific

[leaden torrent]

i mean, if youre considering an actuarial science degree, id assume youre cool with that

if not, uh, do another degree lmao

[ancient flame]

lmao yeah but I can't imagine someone would voluntarily want to do that

but hey

some people enjoy eating tarantulas

[west basin]

money

[ancient flame]

I guess

which is kinda dumb but sure

[leaden torrent]

i get the appeal

[west basin]

finance jobs are known to pay really good

[leaden torrent]

you do a monotonous but ultimately safe and simple job 8 hours a day

go home and get to enjoy a comfortable paycheque

[west basin]

ultimately u have quite good enough job security

[leaden torrent]

its not the most exciting life, but theres a reason "may you live in interesting times" is a curse\

but i wud still assume the work they are doing is intellectually stimulating

considering ur in a math role

unlike say investment bankers

[leaden torrent]

the math is still repetitive calculations and a lot of digging through financial archives

so not really

yeah you do a bit more stats than your average office job, which is interesting for like

a month

but that just becomes like any other computation soon enough

[west basin]

what about something like a research quant

whose job is to actively look for new models

[leaden torrent]

you wont get that with an actuarial degree

those typically require a graduate degree in math/stats/cs/phys

[west basin]

oh ok

[leaden torrent]

mayyybe finance

but not actuarial

[stray kite]

Suppose we add to N a new element x. Then N U {x} is still countable

I feel like this is supposed to be simple to understand but I don't really get it, why is N U {x} countable? To be countable there needs to exist a bijective map from N U {x} to N right? What element can we map x to such that a map remains bijective?

[leaden torrent]

assuming countable means countably infinite here

start by bijecting N into itself

so we have a list

a_1 -> a_1
a_2 -> a_2
a_3 -> a_3
...

you get the idea

now add in x to the top and move everything down

x -> a_1
a_1 -> a_2
a_2 -> a_3
a_3 -> a_4
...

[stray kite]

oh

ok yeah that makes sense

thanks lol

[fair flax]

i see

so basically a bachelors in actuarial sci can lead me to analyze financial risks?

i thought that quant should be more interesting but i dont want to get a masters

i just wanna get into work after bachelors

[fair flax]

is an actuarial sci degree without a masters sufficient for this job?

i am interested in that as well as retirement analysis stuff

[fair flax]

but more interested in this

[fair flax]

i am more concerned with the demand for entry level than the salary

[snow lintel]

guys does have any idea what happened to the brilliant.org calculus page of hard problems?

[turbid epoch]

Is it not there anymore?

You can always use the waybackmachine.

[snow lintel]

no i do not find it anymore

can you check once if possible?

[turbid epoch]

I can't find it.

[snow lintel]

[coarse cobalt]

ok thx

[real sigil]

so sqrt (9) isnt equal to -3?

[real sigil]

so sqrt (9) isnt equal to -3?

[fair mural]

no

the square root of any number is positive

[leaden torrent]

-3 is a solution to x² = 9

[fair mural]

although someone will probably say something about different branches

[leaden torrent]

but the notation sqrt(x) specifically means the principal root

i.e. nonnegative

[fair mural]

there it is

[leaden torrent]

so sqrt(9) = 3

[real sigil]

so the square root and the square are not exactly exactly opposite to each other

[leaden torrent]

f(x) = x² is not invertible on its entire domain

since its not injective

[real sigil]

it makes things alot easier like this tbh

[leaden torrent]

it is invertible on [0, infinity)

and this is the codomain/range of sqrt

[real sigil]

shouldnt you put infinity(?

[leaden torrent]

if you want to denote an ambiguous case where it could be either (or both), use the notation ±sqrt(x)

[leaden torrent]

what?

[real sigil]

precisely

[leaden torrent]

are you french perchance

[real sigil]

[0;infnity(

isnt it like this?

[leaden torrent]

i have never seen that.

ive seen french people use [0, infinity[

[real sigil]

no but im from a country that is frenchish

[leaden torrent]

but ive never seen [0, infinity(

[real sigil]

oh

wait

[leaden torrent]

in any case, in most of the world, [0, infinity) is used

[real sigil]

whats the difference between [ and (

i mean ] and )

[leaden torrent]

] is closed end, ) is open end

[real sigil]

so ) is just [?

[fair mural]

] can be equal

[leaden torrent]

[0, infinity) = {x ∈ ℝ | 0 ≤ x < infinity}

[real sigil]

dude for real ive never seen this lol

we dont use ()

[leaden torrent]

yes, ]a, b[ in the french standard corresponds to (a, b) in the anglo standard

[real sigil]

only []

yeah

french?

[leaden torrent]

the ISO recognizes both

[real sigil]

im form algeria and its how we do it lol

why isnt there one single way of doing it?

smh

[leaden torrent]

because of the bourbaki school

they invented a lot of notation

some of it caught on internationally, some didnt

but it was extra influential on france

the entire world used (a, b) style, but then the bourbakists started using ]a, b[ style

[real sigil]

in that case

which one is more prefered

[leaden torrent]

doesnt matter

write for your audience

[real sigil]

in my books and how teacher does it, never seen him use (

[leaden torrent]

if youre submitting to a journal, it probably has a style guide

[leaden torrent]

then use ]

[real sigil]

fair nough

[leaden torrent]

this really doesnt matter

its a petty notational thing

[real sigil]

if i do ( ocassionally is he gonna get it? ( like he should right?)

[velvet dagger]

Pfft better to bully people into using the more aesthetic notation

[leaden torrent]

probably, but i'd err on the side of caution and stick to what your class uses.

[real sigil]

ye thats about right

[humble cape]

can anyone help me

#❓how-to-get-help

[tawny spoke]

how does one find an advisor and a topic to work on

do i just yolo email a prof and then see if i like their problem

[calm thistle]

Hey, @everyone (yes I am aware at everyone won't work)
Please check out my desmos domain colorer, and give feedback
https://www.desmos.com/calculator/moeh8hg5ng

[vivid halo]

depends, there are a lot of ways around this and it really depends on your personality and your potential advisor's personality

but generally what people do for a bit before choosing advisors is "advisor shopping" in the sense of just like

setting up some meetings/stopping by office hours, chatting about math, see if you get along and if mathematical interactions go smoothly

[bronze pelican]

Ask them what their research is about, do a reading course with them, join their seminar, talk to their students

There are a lot of ways you can get to know a professor and work with them before officially becoming their student

[sly thistle]

Pretty neat, you should join the desmos server

[short pivot]

what... what is the difference between algebraic geometry and geometric algebra

[mild nebula]

Algebraic geometry is the study of varieties (Zeros of polynomial functions in multiple variables) using modern algebraic techniques

Geometric algebra is like vectors but a bit deeper afaik @short pivot

[short pivot]

like vectors but a bit deeper

yes

lol, thanks tho

[mild nebula]

Reading on it a bit more, it's like vectors, but adapted to capture notions of differential geometry

That's kinda cool, I wish I knew more

[hearty glacier]

is there a name for this eqn

[leaden skiff]

is that an inner product?

[hearty glacier]

what are those brackets called

before f and after g

[wild lantern]

Most people just call them angle brackets.

It's pretty common notation for inner products like ninja mentioned.

[hearty glacier]

can i use texit to put eqn in a ppt

[tall badge]

this is a common definition of an inner product on the space of continuous functions on [0,2pi]

[hearty glacier]

how i can show average of cos over full cycle is 0

does this look explainable lol

[thorn heart]

Could someone help me at II pls

[pale orchid]

if you write out the integral, you'll see that you get something proportional to sin(a) - sin(0) = sin(a)

so the result is a sinusoid that is a function of a

then naturally if you change a, you see an oscillating behavior

you have, however, plotted it as a family of functions that depend on the parameter a, and each function is constant

rather than directly making a function of a

[hearty glacier]

should i just call the "notation" in above screenshot inner product in my presentation

[hearty glacier]

Like this?

[pale orchid]

i would put a as the horizontal axis

because the result no longer depends on x

nah nvm bivectord arent that

[river linden]

aren't bivectors basically scalars

[leaden skiff]

only in 2D

[river linden]

hm

I guess write it as a combination of the basis bivectors?

[all the GE i know is from that one video lol]

[meager sonnet]

a wedge b = 1/2(ab-ba)

[leaden skiff]

oh yeah it'd just be another column matrix I'm dumb

[leaden skiff]

you mean GA?

[river linden]

ye

[gloomy marten]

aren't bivectors written as matrices?

Not sure, never heard about them until like when I read that

[leaden skiff]

don't think so?

[gloomy marten]

Bivector (complex)

hmmm

uh

[leaden skiff]

I mean like, you can represent a complex number as a matrix too

[gloomy marten]

yeah true

z = [z]

funny joke innit

def __init__():
```moment

[leaden skiff]

hmm?

I don't get what you're saying at all

[gloomy marten]

innit is british slang for isn't it

__init__(x) is basically the class constructor equivalent in python afaik (i.e. not sure if there are any significant differences)

the first argument of it is the object, the rest are the attributes you want them to inherit (most of the time, you can also just do normal code inside the function (probably))

[neat lintel]

initialize the object

[neat lintel]

no they're written using basis bivectors, like if e1, e2, e3 are you basis vectors one of the basis bivector would be e2 e3

So we just got assigned a project to research on how Multivariable Calculus is involved with our major, of which mine is a Computer Hardware Engineer. Any specific topics I could look to research into? I can definitely see the connections of multivar. calculus with vector calculus & Computer Aided Design, but I’m having a bit of difficulty finding any other specific relations

[neat lintel]

switch your major to physics and then simply say "i'm majoring in multivariable calculus"

[unborn trellis]

I imagine optimization problems are pretty crucial in hardware engineering, and in particular control theory

and in real-life applications, you have multiple parameters, so it's all crazy vector calculus

[neat lintel]

what about optimizations?

multivar calc is used for that

like you'd have to optimize a bunch of stuff?

Desmos gone mad

[wild jay]

butterfly effect

[clever knot]

anyone take physics 2?

and know about the term impediance?

is impedance considered resistance just that it has some time domain

[tall badge]

nothing about time

its just the complex analog of resistance

[clever knot]

hmm

but does the "resistance" overall change at a given time

in something like an RLC circuit

[tall badge]

no

[untold sapphire]

no

impedance is fucking cool

but i don't know how to explain it well

i mean it's misleading to say it has nothing to do with time lol

impedance would be totally meaningless if time were not involved

[leaden torrent]

[untold sapphire]

the whole point of the imaginary part is to capture the oscillating current

instead of the voltages and current being constant they vary as a function of time

[tall badge]

sure. i read the question as impedance having time dependence

[clever knot]

how do I go about understanding it?

we just did all the calculations with converting between phasor and whatever but i don't truly feel like I understand what it means.

[untold sapphire]

i would focus on understanding it graphically. The magnitude of the impedance phasor determines |V|/|I|

and the phase of the impedance determines arg(V) - arg(I)

[clever knot]

i am trying but I can't find any simulation

I just wanted to screw around and see the different values/ graphs or whatever.

[untold sapphire]

Before this gets deleted by reddit admins, this asshole took it completely out of context. First of all, the idiot thinks it was a marionette deck. It wasn't. That card's not even in the deck. He was running counterspell draw, this was approximately turn 25, every single creature and spell I cast was countered or removed up until that point and this dumbass who copied his deck from MTG Salvation or Goldfish used one of his last copies of negate to counter a Revel in Riches when he had 0 creatures on the field and I had 0 treasures in play, thus the "this spell does literally nothing" and he should have let it resolve. I love it when people copy a deck and have no idea how to run it or play MTG. I was just throwing it out because I had 5 mana and it was the only card left in my hand and the game was already over anyway. So on the way out I let him know what an idiot he was for countering a spell that does nothing in the current board state.

NOBODY wants to watch a recording of a game where I cast something and he counters it or removes it x30 turns. That's idiotic. I should have left the game the second I saw what he was running. This was the 5th attempt at getting a recording of something resembling watchable MTG gameplay and 5 people in a row were playing Karn draw control loop or free cast torrential graveyard resurrection control or approach control loop. So yeah, I was pissed and he was an asshole for playing this. He's one of those idiots who doesn't care about the other players one bit, it's all about winning. So running 35 control spells seems reasonable because NOTHING matters but winning. Thanks for not showing the board state with library counts or the full log, asshole. Enjoy your temporary ban from reddit.

Hi everybody,

Im new to this server, i'm not a numberphile. Although i like numbers...

... Im looking to speak to someone who is good with and passionate about predictive mathematics, specifically, probability and is good at creating models for resolving these problems. Also highly self motivated.

Is there anyone here that this appeals to?

Bro, imagine if we are clowning a kid right now.

He just learned all the big words and we're shaming him.

[brave hollow]

its not a kid its a job offer from numberphile for their next video 🙂

bro

this power series shit for ode's is hurtiung my brain

it all makes sense up until we establish the recurrence relation

and start figuring out the pattern

[last oxide]

yeah, thats the meme part

actually the even more meme part is finding out what the power series corresponds to at the end

[mint patio]

can you even do this half the time XD

[last oxide]

the exercises are made in such a way they tend to be elementary functions

but most of the times they wouldnt be

[mint patio]

yeah I figured

[last oxide]

actually thats the importance of it

you can write down an analytic function

that is not necessarily elementary

[mint patio]

are all real valued functions just u(x,y) + iv(x,y) with v = 0 lmao

[last oxide]

I mean
of course
isnt that how u is defined

[mint patio]

is that how you'd check analyticity using CR on real functions??

[last oxide]

no

[mint patio]

yeah that doesnt make sense

do you just use definition then

[last oxide]

complex analytic is not real analytic

[mint patio]

oh

real analytic is a diff thing

ok

[last oxide]

well
they are both writing in power series
