How’s everyone

[neat frost]

youre the nerd, nerd

[maiden belfry]

how much math is there?

can you beat math?

[odd narwhal]

you can damn well try

[jade crane]

Has anyone worked with a partner for an entire semester and not know their name

I just realized I don’t know my partners name who I worked with for the entirety of my math modeling class on projects with

[neat frost]

Be like “bruv I know we’ve been working together for this whole semester but frankly, you’re just not important enough to me for me to remember your name. Unfortunately, I feel awkward not knowing it, so I feel obliged to once again ask you what your name is so I can forget it again later.”

And then you’ll be fine

[alpine kindle]

wait is wew muted

[neat frost]

Yes

[neat lintel]

I can't say that's ever happened to me, but sorry for your loss

[bright hill]

for how long should you study math a day?
or rather, for how long do math majors study a day?

[tender musk]

No idea, I guess for 2-3 hours although I am not sure

[inner finch]

what why

[deep mango]

being too mean to someone who asked for help i think

[jade crane]

elitism

[blazing pawn]

That and being mean to someone who answered them

[neat lintel]

am i allowed to cross post a question between servers?

[mint patio]

Between servers? LOL

I don't think anyone cares

Go for it

[tribal dove]

“The derivative of x is 1” - 🤓

[devout nacelle]

This can lead to wasted efforts of helpers on any of the servers you post in, so it might be a good idea to at least acknowledge on all the servers that you've already received help when you do.

[neat lintel]

i wouldve if i got help lol

i buckled down and got it myself though

[devout nacelle]

Good job

[neat lintel]

😄

[west sundial]

Genius

[violet cloak]

Just curious if anyone would know anything, but would there be such thing as a say a "roadmap" in terms of learning mathmatics? from basic high school algebra(pretty much where I left off) And going into / understanding more advance college level topics?

[serene sigil]

how the hell does one study when there are [massive world events] happening

[terse flax]

coz fuck world events

[verbal pivot]

agree

[fading hull]

Sure just 100% khan academy

[violet cloak]

Ah that's fair

Thanks

[ancient geyser]

hey

$\lim{x \to 0} f(x) = \frac{sin{x}}{x}$

[fathom swallow]

OreoFTW

[ancient geyser]

the answer to this is 1 right, but what if the function is sin(x+k)/x+k

basically adding a constant

[pale orchid]

please check #❓how-to-get-help

[ancient geyser]

hm okay

felt like this would be a small ques for a help channel haha

[pale orchid]

that's what they're for

Squeeze thereom

Or just use lhopital like a boss

[neat lintel]

Can someone explain l’hopital to me

[primal crater]

[stray kite]

is analysis enough as a prerequisite for a course in general topology?

[blazing pawn]

Yes

[loud iris]

h gets so small

[tribal dove]

Is there such thing as an infinitesimally small number

Like the first number after 0

Wait no obv not

[fair mural]

[cyan goblet]

if someone's good at physics please help 🙏

not sure how to approach this

[median zinc]

Maxwell's equation on induction

[cyan goblet]

$\varepsilon = -\dv{\Phi_B}{t}$?

[fathom swallow]

anamono

anamono

[toxic schooner]

without the external force, the answer is emf=BLV, so V=emf/BL
idr how to account for F

[median zinc]

yet another EM equation

Lorentz Force

[cyan goblet]

im gonna be real

this is algebra based physics

ik

so yeah we haven't really learned any of that

[median zinc]

Point is if F is unbalanced, velocity changes

[cyan goblet]

i know calculus just dont know how to connect the ideas between the two yet

[median zinc]

I heavily doubt it. I'm just using slightly higher level vocabulary than what you learn it as

[cyan goblet]

perhaps, or we're given some simplified version

[median zinc]

Yes, you are

If so

[cyan goblet]

the equation sheet we're given doesn't have any curl operators

[median zinc]

Read your notes

[cyan goblet]

unfortunately maxwell equations are not in the curriculum for AP Physics 2

it is for AP Physics C, but i'm in 2

[median zinc]

Read your notes

[cyan goblet]

it can be assumed that im asking for help because my notes do not suffice

if my notes sufficed i wouldnt be asking for help

[median zinc]

Then google what I wrote.
There's libretext that covers this directly
https://phys.libretexts.org/Bookshelves/College_Physics/Book%3A_College_Physics_(OpenStax)/23%3A_Electromagnetic_Induction_AC_Circuits_and_Electrical_Technologies/23.06%3A_Motional_Emf

[cyan goblet]

this is useful thank you

i googled "Maxwell equations on induction" and only got information about maxwell equations, not motional emf

[median zinc]

[stray kite]

philosophically controversial question

[alpine kindle]

depends on what you consider a number

[tribal dove]

it would be cool if desmos said f(15)=5

[median zinc]

You are not writing intervals, you are writing lists

[stray kite]

i think for intervals on desmos you have to use { only?

or something like that

[fair mural]

yeah

[tribal dove]

how do i do that

[tender tulip]

That’s like asking infima or suprema of continuous/Cauchy sets

[wise vigil]

I am very stupid. This is not possible right?

It saying that you approach -inf from the left right?

[ripe wasp]

that was the joke

[stone ferry]

Yeah, not really a thing. It's saying you're coming from "less than" -inf, which isn't real

[wise vigil]

Yea that makes sense

[wise vigil]

Yep

[jade crane]

is it normal for academic advisors to be absolutely useless the ones here literally just tell me the bare minimum to "graduate", their advice doesn't seem good. Like my professor who taught me analysis's course/topic suggestions are better than theirs.

[vivid halo]

yeah that's normal

[velvet dagger]

Fairly common. I honestly don't see a huuuge point in having so many academic advisors given that a catalog usually exists

[neat lintel]

I think if they are in the department they could be good buddies to chat with about potential interests

[brave idol]

How do I prepare for MIT??

[bright hill]

I think they have a "what we look for" page

I guess you could start by reading that

[vivid talon]

You will apply for MIT ?

[brave idol]

Yeah. I really like making stuff and am into engineering and programming

[vivid talon]

OMG this is Awesome !!!!

I wish u all the best

[brave idol]

Thanks.

[brave idol]

Wdym?

[vivid talon]

I think he mean by this message "try to search and read about your question by yourself"

[bright hill]

they have a page on their website called "what we look for"

wdym "wdym"?

[brave idol]

Can you send a link by any chance. Can’t find it.

[brave idol]

It means, what do you mean

[fair mural]

that’s not what they meant

[brave idol]

?

[devout nacelle]

Why would they ask "wdym "wydm"" if they didn't know what "wdym" stands for lmao

[brave idol]

Just realised

Then what is he asking

[devout nacelle]

They probably wanted to ask which bit about what they said confused you

[neat lintel]

I need some support

A compact support

[bright hill]

https://mitadmissions.org/apply/process/what-we-look-for/

[vagrant gull]

oh yeah I applied for MIT this year

got deffered and will learn this march

[vagrant gull]

got rejected from Olin

[blazing bramble]

I just had a weird though. What are the economics of n-dimensional real estate. I mean in a 4d universe, your house would need 2 more walls. Is it more expensive to buy a 4d house than a 3d one? Could a 4d house be smaller, as it has a higher square? cube? footage?

[neat lintel]

it should be cheaper

if 4d space is way larger than 3d space

and we already fit in 3d

[blazing bramble]

I'm assuming the people in the 4d space are 4d as well

[neat lintel]

lol

scaling is funny topic

[blazing bramble]

please ignore whatever other unrelated junk is entailed by that lol

[neat lintel]

think about it this way

imagine having a hyperplane in 3d

isnt it super small compared to the vastness of 3d

or better yet you can just use formulaic approaches

imagine we are talking about distances for example

and you want the diagonal of your room to be 70ft atleast, from opposite corners

in 2d this just corresponds to having 50 ft walls if you live in a square

in 3d it comes down to solving 70/sqrt(3)

[fair mural]

what the heck

[neat lintel]

which is 40

in 4d

this is 35

[blazing bramble]

lol

[neat lintel]

so where you would need 40 feet side cube to have 70 foot diagonal in 3d

you only need 35 in 4d

there are 6 walls in 3d

so this means we need 40*6 feet of wall

while in 4d we would need 35*8

but this is assuming 4d people needs scale linearly with 3d people needs

we know that if we were embedded in 4d we would take up a lot less space

[blazing bramble]

well 35*8 is more than 40*6 so it would take up less space, but cost more meterial

[neat lintel]

but this is on a faulty assumption

say a colony of ants need 40 square feet to live comfortably

they dont need 40^1/3 foot walls in each direction 3d because ants are relatively 2d creatures

[blazing bramble]

ah, so realistically, a 4d person would need a smaller house anyway

[neat lintel]

yeah

like we dont build enormous ceilings for ants

similarly our 4d walls dont need to be enormous

so this would have an effect of shortening the less needed walls

and still giving us the necessary protection from 4d world

[bright hill]

I think only a 4d person can live in a 4house

[neat lintel]

no

3d people can live in 4d house

[bright hill]

coz otherwise, you'd have infinite number of houses

the economy of real estate would collapse instantly

[neat lintel]

depending who owns what?

if the world was run by 4d people

3d people would be pets most likely

similar to how people put insects in small cages

[fair mural]

idk if this is the worst or best conversation i’ve seen here

[neat lintel]

why so judgemental?

[bright hill]

that's interesting

the thing is

we don't really have a 2d analogue to project

[neat lintel]

the closest thing we have are insects

and how they dont need latge height containers to live

and live in relatively flat environments

or like microscopic life

[bright hill]

how about that japanese egg game which you could feed or whatever?

[neat lintel]

squid game?

[bright hill]

no lol

I forgot its name

they're called digital pets

[neat lintel]

🤷

[cyan goblet]

tomogatchi?

or something like that

[fair mural]

it’s just a very unusual conversation

[fair mural]

sounds right

[bright hill]

tamagotchi

you were really close

anyways

[alpine kindle]

you're thinking of tomodachi life by nintendo

[cyan goblet]

yes i was actually

was trying to think of the name and the first thing that came to mind was tomodachi life

[bright hill]

fun fact: tomodachi means friend

[cyan goblet]

but i knew that wasnt it and i remember there was some g sound in it

yeah that's why i guessed tomogatchi instead of tomodachi lol

[alpine kindle]

miitopia is a cool game

[cyan goblet]

RIP wiiverse 🙏

[bright hill]

I thought about it a bit and I concluded it's meaningless to speculate what 4d creatures would do

[neat lintel]

yeah

its only meaningful if you have schizophrenia

[blazing bramble]

lol

[river linden]

we are 4d creatures 🙃

[bright hill]

we mean spatial dimensions

[vast surge]

I noticed a significant gap in the mathematical literature. Specifically, there are no wikihow guides for advanced mathematics. (ie, no "how to calculate the rank of an elliptic curve", no "how to calculate homotopy groups", no "how to calculate the ideal class group of a number ring" or "how to find the galois group of a polynomial"...)

[long matrix]

no "how to solve the riemann hypothesis" 😢

[vast surge]

Someone should add "solve the riemann hypothesis" to the "how to become a millionaire" page

[fathom tendon]

Is it common to have really bad imposter syndrome with math

[ripe wasp]

i get imposter syndrome every time i attempt a problem in my book

[vast surge]

Yes. I know professors who complain about imposter syndrome, and I'm an undergrad.

[novel vine]

would someone be willing to help me in my channel

[mellow moon]

This is because general usual higher (advanced) maths structure/problems encountered does not have general method to deal with problem with out too much loss of generality.

[dire sandal]

hey fellas

[dire sandal]

i mean why do you think you feel that way

[mellow moon]

In the sense that a minor modification, can introduce a change of the whole theory

[fathom tendon]

Because I see so many people online and in YouTube videos and stuff talking about math and I don’t feel like I’ll ever be able to understand the stuff

[mellow moon]

this is normal, this take time

a lot of time

[dire sandal]

we were all there

you also have to remember that these people have devoted years themselves to do these things

and are still devoting years to understand higher maths than they know

[charred mortar]

I’ve found that a better way to approach it might be to reframe your thinking as “I’ll make sure I am on that level, to show that I deserve my position”

[cyan goblet]

am I supposed to know real analysis before reading Goldrei? #books-old doesn't list it as a prereq but he references real analysis a lot

e.g.

[modest rune]

it is often assumed that real analysis is the first real math subject people learn

[cyan goblet]

shiit

so should i go and read a real analysis textbook then come back to set theory

ok actually i know most of this

all i dont know is 1.1 to 1.3

which i guess 1.1 is what's going on now in goldrei

and 1.2

[neat lintel]

know is a big word

also sorta backwards if you dont know 1.1-1.3 but know everything else

its like u blackboxxed foundations

[cyan goblet]

i guess "dont know" in the sense that i wasn't taught how real numbers were constructed

[neat lintel]

oh

its pretty cool

maybe cool is wrong word

[dire sandal]

real numbers are constructed from 2 + 2 = 4

duh

[cyan goblet]

lmfao yeah im reading about it in goldrei rn

pretty cool

topology has never once come up in my schooling

IVT is apparently topological, but we were never taught the connection

[neat lintel]

it isnt essential i guess

yeah its topological

i think it comes from this theorem about regular spaces?

i forgot names though

[modest rune]

the connection is that you can phrase it as "the continuous image of an interval must be connected"

[cyan goblet]

ah i see

[modest rune]

effectively this is just a very weak form of the fact that continuous functions preserve connectedness

it just so happens that connected subsets of R are just intervals

[neat lintel]

i need review );

[river linden]

real analysis is a good motivation for topology, idk how you'd understand the "every open cover has a finite subcover" defn without knowing its equivalent to "closed and bounded" in a metric space

hopefully he mentions that

[blazing pawn]

There are good intrinsic reasons why the definition of compactness makes sense

[odd narwhal]

it's not equivalent to closed and bounded in a general metric space. It IS equivalent to complete and TOTALLY bounded in a general metric space

[blazing pawn]

But they are more abstract I guess

[odd narwhal]

also compact always implies closed and bounded whenever boundedness makes sense

[deep mango]

[odd narwhal]

???

you can make any metric bounded

[deep mango]

yes my favorite compact space is Q intersect [0, 1]

[odd narwhal]

oh woops

meant complete

[deep mango]

closed -> complete

[odd narwhal]

my b

yeye

[blazing pawn]

Me too 🙂

[deep mango]

the vultures are descending. they smell a vocabulary mistake

[odd narwhal]

anyways my point was closed and bounded is not sufficient

rescind your sully now

[deep mango]

no.

[odd narwhal]

i'm so gonna ban you when I inevitably become mod

[mint patio]

I will defer to John

[deep mango]

yeah i'd make a good grandma

[odd narwhal]

you're definitely gr

[blazing pawn]

I think its one of those situations where both of you are both

rycope as per usual

[mint patio]

ryc did not like that one

[deep mango]

oh come on moth. fencey fencerton

[mint patio]

any shin sussy bakas

[deep mango]

😮‍💨

[fair mural]

feather what book are you using for probability

[blazing pawn]

anyway: the intuitive answer here is that compactness generalizes finiteness by letting you check many properties on finitely many open sets rather vs finitely many points

[odd narwhal]

some people in this server have a conspiracy theory that i'm actually a woman

[mint patio]

the shittiest one there is
probabilitycourse.com 😎

but I just read my prof's notes lol fuck that site it's so weird

[blazing pawn]

In the sense of like, suppose i have a property P. P might hold locally if theres some open cover of your space such that P holds on each set in the cover

for a finite discrete set for example this is literally just checking P on every point

[fair mural]

darn i thought it was good

[deep mango]

the really useful thing about this "checking properties on finitely many open sets" thing is that it lets you take local information and turn it into global information

[blazing pawn]

and many properties will then trivially extend to the whole space when working in the finite case

[deep mango]

for example, a continuous function on a compact set is actually uniformly continuous: if we know something about how much it varies it in each little ball, we find out something about how much it varies on the whole domain.

[blazing pawn]

compactness is kind of similar where if i have a local property P this means P holds on U1, ..., Un where the union of the U_i are X

Its usually a lot easier to show that P holds on X if it holds on these finitely many U_i than it is for infinitely many

I think the common example is that like real valued functions on compact sets are bounded

This is extremely obvious if the set is finite

[deep mango]

yeah that's a good one

(continuous real valued functions)

[blazing pawn]

Good thing that while ryc and shin were fighting like children i was making valuable contributions to the mathematics discord server.

🙂

[odd narwhal]

like children?

ryc started it

[mint patio]

https://tenor.com/view/ah-shit-here-we-go-again-ah-shit-cj-gta-gta-san-andreas-gif-13933485

[deep mango]

shin and i both provided answers

[blazing pawn]

no one cares about metric spaces

[deep mango]

his was wrong, but

[blazing pawn]

Lmfao

[deep mango]

it was right in spirit

every relevant topological space is either metrizable or a function space

sorry, i'll revise that

every relevant topological space is either CW or a function space

[toxic schooner]

CW?

[deep mango]

CW complexes are a type of space

which are kind of like higher dimensional graphs

you take a bunch of points, glue a bunch of lines to them, glue a bunch of disks onto the lines, glue a bunch of balls onto the disks, etc

using such a construction you can make almost all of the usual nice topological spaces we want to understand

[toxic schooner]

Oo

[deep mango]

for example, one way to make a sphere is to take two points, glue two lines to them, and then glue a disk on top and on bottom of the lines like this

(the red pieces are two disks)

so this is a CW structure for the sphere

[toxic schooner]

[odd narwhal]

I FIXED IT

[deep mango]

turns out that there's a whole machinery to understand the topology of CW complexes. you can compute different topological facts about your space if you think about it as a CW complex, since this lets you compute its homology

lots of people ONLY care about CW complexes (and there's a whole lot of them too)

unfortunately most spaces in functional analysis (infinite dimensional spaces of functions) are not CW and they're the only ones i care about

[toxic schooner]

[toxic schooner]

big sadge

[river linden]

I get this, it's just if i saw the topological definition by itself I'd think "wow that's a super nice property, I bet hardly any sets satisfy that". but idk much topology so maybe theres a nice way to see closed bounded balls are compact without resorting to the sequence slicing proof by contradiction i know

[odd narwhal]

closed bounded balls are not necessarily compact in a general metric space

you can make any metric bounded by taking its minimum with 1 for example, and this makes every set bounded, but this won't make a non-compact space compact

the stronger requirement is total boundedness, which means for every epsilon>0, you can cover you space with finitely many open balls of radius epsilon. This might sound similar to compactness, but it's quite a bit weaker given no extra assumptions

[river linden]

I'm taking about euclidean space and intuition here don't nitpick

[odd narwhal]

at no point did you make that clear, especially since before you claim that closed and bounded is equivalent to compact in a metric space, which is a false and somewhat misleading claim, even if it follows intuition. I'm not trying to call you out, i'm just trying to clarify a subtle distinction here for you and/or anyone who stumbles upon this discussion in the future

[river linden]

its fine, just everywhere in rudin we work with complete metric spaces which are subsets of R^n so i figured i dident need to mention it

[odd narwhal]

that's fair. I think generally when talking to someone who doesn't share the same background/base assumptions as you, it's better to be over specific than to be ambiguous and risk confusion as here. euclidean space is generally much more well-behaved, and things that feel intuitive and that indeed hold true in it sometimes don't even generalise to a broader class of metric spaces, so it's good to be precise when discussing these topics

well that's cleared up now, no point to dwell on it

[deep mango]

i would say that the sequence splicing proof kind of is the essence of compactness of closed balls in R^n, and i say that because the proof that complete + totally bounded = compact for metric spaces is almost identical looking.

but i don't have a good way to argue this

[empty sundial]

What can i do with spare 5k savings?

[leaden torrent]

invest it

[stray kite]

send it to me

[river linden]

buy 5 textbooks

[alpine kindle]

ok you have 5k left

now what do you do

[river linden]

buy more textbooks :)

[neat frost]

5k? Obviously the only rational thing to do is to invest in some NFTs

[empty sundial]

Oh god

😂

Hmm

[sick burrow]

Honestly just save it

Or invest it but I don't know investing that well

[modest rune]

just invest in the S&P if you dont need liquidity

if you want to be as lazy/safe as possible

(i am not a financial adviser dont sue me)

[velvet dagger]

Suing you for not being a financial advisor

[median zinc]

S&P500 moment

[river linden]

lol

[modest rune]

?

what is this supposed to show lol

[median zinc]

loss

[modest rune]

over 2 hours lmfao

this is a real SP 500 moment

Compare with inflation of 14% over the same period

[bright hill]

whoa

that's really cool

[modest rune]

for 99% of people, the best possible way to invest is to invest as boringly as possible and not touch it

i still don't know what you are trying to show

[median zinc]

It's a joke

It's half a joke

[modest rune]

i dont see the joke

[median zinc]

The joke is, you'd lose money if you actually bought S&P500

high chance at least

for past few weeks

[modest rune]

That is completely untrue lol

sure

past few weeks

investing on that scale is incredibly dumb though

[median zinc]

not really

there are a lot of S&P day traders

That's intraday scale

not even weeks

[modest rune]

Day trading is not what I am suggesting at all, though

[median zinc]

Anyway S&P500 has a high CAGR

clearly visible for every year

so

yeah I mean

sure beats the 10-year treasury yield

[modest rune]

didnt it also beat like

50% of hedgefunds over the last decade or something

[median zinc]

It beats a lot of active traders

And well, hedge funders are generally, not passive traders

But like I'm always hearing of algotraders making bank

No clue who to believe

[modest rune]

personally i believe data, so these hedge funds or algotraders with limited disclosures don't mean much to me

im sure there are outliers making bank

but at the end of the day, I doubt i could be one, so i just invest boringly, imo

[leaden torrent]

day trading as an everyman is essentially gambling fwiw

thats like

the whole point

its gambling where the margins are, on the margin, better than a las vegas casino (at least until an economic crash) sure

but its still gambling

if youre working at a hedge fund with an army of specialists and ML algorithms on your side then thats different

[bright hill]

is there anyway to get a more uh "geometric" feel for topology? im just beginning reading

[neat lintel]

yea

for finite topologies

you can draw open sets

then for other topologies it might be more useful to understand them in terms of their basis

all in all it depends on the context and since the subject is big on studying the structure of space it is very visual at its fundementals, but lots of extrapolation is made to not think of the visual later on

could anyone here possibly help me with a digital design circuit question?

[toxic schooner]

what does mine tell u

[bright moat]

Can someone advise me on math classes? Cause my school allows people to jump grades in math. I'm G8 currently.

Should I move into G9 this year or just try to bump up to G10+ in G9?
Cause G8's almost over

But idk if I can make it to 10 in 9 since I never took the classes. If I decide to take 9, I'll be barely through by the end of the school year which means they might not raise it.

11 is going to be hard since I don't have any particularly official G10 material

But making a jump straight from 8 to 10 is going to be a bit hard.

And even if I make 10, it's going to be a lil too easy

It's not even guaranteed that they'll raise me, although I think with my current teacher's help, I might be able to.

What do I do.

jump rn, or jump later and further with the risk not being raised

[vast surge]

It's generally considered rude to take more than one channel

[bright moat]

it is generally neccessary to calm me down when I'm panicked as hell

[vast surge]

That said, I don't know what G9 or G10 means in this context, so good luck.

[bright moat]

Grade

[vast surge]

Sure. What do you do in 9th grade or 10th grade?

This is a very international server, and we have no way of knowing the education system where you are. Especially because it often varies even within countries

[bright moat]

9, polynomials and circle geom + slope
10, graphy stuffs, more algebra stuff, probably trig

[bright moat]

canada

[vast surge]

Sweet. How standardized is the Canadian curriculum? Is it the same in Ottowa as it is in Quebec?

[bright moat]

they teach pretty much the same stuff everywhere, at most with a 1 year difference, order may change as well

(mainly because the order depends on the teacher)

[vast surge]

Well polynomials are just about the single most important thing you listed on that list, so do the one where you learn polynomials. I don't know what you'll be learning in polynomials, I'm still doing polynomials and I'm in my 3rd year of college, but they're important so learn them

[bright moat]

already done, I just wanna know if I should risk jumping rn or later (later being riskier but with higher rewards)

[vast surge]

Talk with your teacher about it. They'll know your situation better than I would, certainly.

[bright moat]

probably a good idea

*apparently did not come along in their thoughts

thanks

[vast surge]

Oh my god wait were you seriously considering skipping a grade solely on the advice of potentially some rando you met on a discord server you probably only recently joined? Because if so, then please, do that, that'd be hilarious

[bright moat]

I want to skip because none of my previous teachers took my math skills seriously and continued to teach me stupid crap

I swear it's the only reason my IQ dropped (sarcasm)

but really, the past 9 years of my life spent on math has been absolutely torturous

NOW THAT SOMEONE ACTUALLY TAKES ME SERIOUSLY, WHY NOT.

[vast surge]

I mean you can also just learn math on your own time and take the easier course for the easy A

Use Khan academy to teach yourself through to calculus or something, read free textbooks, watch Richard Borcherd's youtube channel

If you think your school is too easy, then it probably is, so that shouldn't be your primary mode of learning (rather, just proof that you learned the thing you wanted to). If you think skipping a grade will bring you to where you want to be, do that. Otherwise, teach yourself calculus and linear algebra and whatnot in your free time (the time that you otherwise would be spending on math homework if it was enough to challenge you).

[bright moat]

if I don't skip, it'll be another year of torture

;-;

but I'll still ask my teacher

[vast surge]

No it won't. It'll be a year of somewhat boring lectures that you power through or doodle in the margins during with maybe an hour a week of easy homework and then you spend your free time learning something hard enough to challenge you. Or watching YouTube videos of kittens being adorable, or doing something else. "My math classes are too easy, woe is me" is only torture if you let it be.

[bright moat]

The torture only comes when homework is there. I don't wanna spam do such work when I don't have to.
The reason I want to jump is because I don't have any clear curriculum to follow and I'm not learning to the same amount as anyone who actually took the classes. I just watched some random youtube video. Math won't be very clear when you learn logarithms before you even know anything first

[vast surge]

Okay so here's a bunch of free textbooks: https://openstax.org/subjects/math

[bright moat]

glorious, thanks

[vast surge]

Do exercises, speak with your teacher during... Do your teachers have office hours, or is that just a university thing?

so idk

I can ask after school

she's usually there till 4 ish

[vast surge]

Oh and Khan Academy has good lectures. Go to khanacademy.com or whatever their site is and start working through it

You can do a lot with self-studying. The main issue is you'll lack someone to give you feedback, but khan academy does that and if you get on your teacher's good side they can do that (if they're qualified to teach 8th grade math they'll hopefully at least know what a derivative is, or will be able to direct you to someone who does). Worst case scenario you just ask questions on the internet in sketchy places like this full of weird 24 year olds who devote their lives to the cult of mathematics.

[bright moat]

IQ isn't meaningless, although the second part is true

[vast surge]

You're right, it's a bloody good measure of your IQ. It just doesn't really tell you anything beyond that.

George Bush had one of the highest IQ scores of any president to have taken an IQ test (somewhere above 130 I think), and he was George Bush.

[bright moat]

there's also measures like verbal

[bright moat]

eh, wether or not you have high IQ, there is a high chance you'll end up average

130?

oh, average of 125

i see

*googled

[vast surge]

Well it's a normal distribution with 100 as the average and a standard deviation is 15 points on the IQ test, so having 130 means you did a lot better than most people on the test.

[deep mango]

[bright moat]

dunno the percentage, but I think it was some 97-98

[bright moat]

110-140

big range

30 difference

but with that, there's a bigger chance that he ends up gfted than not

[vast surge]

Oh and Trump had an IQ of about 160, according to a quick internet search. Having a high IQ really does not mean you're smart.

[bright moat]

160?

I estimated around 90 (sorry if that's offending)

90 - 110 ish

[vast surge]

90 would be firmly within the average range that most people fall within, if a little bit on the lower end. "You're about as smart as most people" is not an insult. (Even if I agreed that IQ measured intelligence, which it does not)

[bright moat]

*shrugg

IQ was supposed to measure intelligence

oh right

what IQ or above would you consider high

[vast surge]

I mean yeah but the angle of your forehead was also supposed to measure intelligence and nobody takes phrenology seriously anymore.

To be fair, you have to have a very high IQ to understand Rick and Morty. The humour is extremely subtle, and without a solid grasp of theoretical physics most of the jokes will go over a typical viewer's head. There's also Rick's nihilistic outlook, which is deftly woven into his characterisation- his personal philosophy draws heavily from Narodnaya Volya literature, for instance. The fans understand this stuff; they have the intellectual capacity to truly appreciate the depths of these jokes, to realise that they're not just funny- they say something deep about LIFE. As a consequence people who dislike Rick & Morty truly ARE idiots- of course they wouldn't appreciate, for instance, the humour in Rick's existential catchphrase "Wubba Lubba Dub Dub," which itself is a cryptic reference to Turgenev's Russian epic Fathers and Sons. I'm smirking right now just imagining one of those addlepated simpletons scratching their heads in confusion as Dan Harmon's genius wit unfolds itself on their television screens. What fools.. how I pity them. 😂

And yes, by the way, i DO have a Rick & Morty tattoo. And no, you cannot see it. It's for the ladies' eyes only- and even then they have to demonstrate that they're within 5 IQ points of my own (preferably lower) beforehand. Nothin personnel kid 😎

Math server IQ discourse

To be fair, you have to have a very high IQ to understand mathematics. The deductions are extremely subtle, and without a solid grasp of foundational logic most of the proofs will go over a typical learner's head. There are also Gödel's incompleteness theorems, which are deftly woven into mathematical research- they pertain to Cantor's Generalised Continuum Hypothesis, for instance. The mathematicians understand this stuff; they have the intellectual capacity to truly appreciate the depths of these proofs, to realise that they're not just rigorous- they say something deep about LIFE. As a consequence people who dislike mathematics truly ARE idiots- of course they wouldn't appreciate, for instance, the subtlety in the existential "Hairy Ball Theorem," which itself has cryptic connections to Euler's characteristic and planar graphs. I'm smirking right now just imagining one of those addlepated simpletons scratching their heads in confusion as the unparalleled beauty of mathematics unfolds itself on their e-book reader screens. What fools.. how I pity them. 😂

To be fair, you have to have a very high IQ to understand the hit game called "Among Us" The lore is extremely subtle, and without a solid grasp of storyline connection most of the hints will go over a typical player's head. There's also the mystery of the impostor, which plays into it's character. The impostor's personal philosophy has a high probability of not being referenced inside any literature, for instance. Only a select few of fans understand this stuff; they have the intellectual capacity to truly appreciate the depths of these mysteries, to realise that they're not just a game, they say something deep about LIFE. As a consequence people who dislike Among Us ARE idiots- of course they wouldn't appreciate, for instance, the humour in the crewmate's tasks. Which in itself is a cryptic reference to how repetitive this society truly is. I'm smirking right now just imagining one of those addlepated simpletons scratching their heads in confusion as Innersloth shows his ingenious game design which unfolds itself on their device's screens.

[cyan goblet]

isnt probability just how likely something happens

statistics is the analysis of data

[fading pulsar]

no

[long matrix]

In statistics, you are trying to deduce the probability distribution from data, you could say

You are given the data

and you are trying to figure out what models it

[fading pulsar]

I have never seen high level statistics (yet)

[cyan goblet]

or are we talking probability in a diff context

[long matrix]

In science, you are also given the data

and trying to see what mathematical model applies to it

[fading pulsar]

What is the equivalent of a textbook like varadhan's text on probability theory for statistics?

I'm just curious to see what statistics is about

[cyan goblet]

that's probably a question for #book-recommendations

might have better luck having that seen in there

[little vine]

A statistic is anything that can be determined from data

I was doing great in stats until I got to estimators. I don't really get how we can tell an estimator is unbiased unless we actually know the true value of the parameter

[devout nacelle]

Combinatorics or discrete math, maybe?

Hi I have a linear algebra question

Could you have a dot product of a matrix? Or would it only work if that matrix was considered as a vector?

Let me give you an example to make my question clear to you.

So if I try to find the product of a matrix with dimension (2x1) with another matrix with the same dimension (2x1), it wouldn't be valid because the number of columns of the first matrix does not equal the row of the second matrix.

However, if I were to define the 2 matrix to be a vector, I would get a scalar value by dot product.

If that's the case, you could consider any matrix as a vector and make every matrix dot product valid.

I'm just so lost. Help me plz 😦

[neat lintel]

The dot product a.b can be defined as a^T b (matrix multiplication of a^T and b)

But it makes little sense if doesn't return a scalar

Yo anyone good with english literature?

yeah I know they were being unreasonable, just wondering about topic choice in general

[steep mountain]

its not that no one here is knowledgable with english literature i assume many people are

[neat frost]

English has no place here

It can go to #chill

[long matrix]

I wouldnt find it a problem myself if someone just asked an English Q

[steep mountain]

but it simply would make sense to ask this somewhere else

tho i will try to explain that message

[charred mortar]

understandable

[long matrix]

And then they were directed to somewhere more helpful

[steep mountain]

as best of my ability

[long matrix]

or maybe someone could actually help. but thats not what happened here

[charred mortar]

for sure

[steep mountain]

"I repeat that the turmoil of heterogeneous and antagonistic social whims and speculations in which we live is due to the failure to understand what the industrial organization is and its all-pervading control over human life"

[long matrix]

Im afraid I cannot decipher this

[charred mortar]

me neither tbh

[steep mountain]

so here is my thoughts in understanding a sentence with odd or difficult literature

[charred mortar]

my brain just kinda skims over it

[steep mountain]

1st of all lets cut this to small pieces

[neat frost]

Tbh the sentence itself isn’t too bad, just weirdly written and it starts with “I repeat”

And idk those big words, but

[long matrix]

context would probably make it make much more sense too

[steep mountain]

and immediately im struggling with
turmoil of heterogenous and antagonistic social whims and speculations

[neat frost]

,w define heterogeneous

[long matrix]

i did the same lel

[neat frost]

Hmmm

[long matrix]

it is just a synonym for 'different'

i suspect

multitude of

variety

[neat frost]

Okay I’m getting the feeling that the sentence may not make logical sense maybe?

[long matrix]

antagonistic meaning clashing

[charred mortar]

ngl this reminds me of Orwell's pseudo-rant on politics and the english language

it feels like a bunch of big words strung together to sound fancy and overwhelming

[neat frost]

Yeah

[blazing pawn]

The sentence makes sense

[charred mortar]

e.g. "heterogeneous and antagonistic" feels redundant (just say antagonistic)

maybe I'm just bad at comprehension though

[neat frost]

Who was that physicist that published an article in some social science journal that made no sense?

[steep mountain]

so we can phrase this as
"the disturbance of social needs and demands usually ones that are sudden to happen and change"

[blazing pawn]

It's basically just "our society has a bunch of contradictory social demands because we don't understand industrial organization and how it controls our lives"

[charred mortar]

ah I see

[steep mountain]

is due to failing to understand how companies take control over peoples life

[long matrix]

unveiled secret: to become a mod u must pass an english test like this

[steep mountain]

hmm

ye ultra statment seems somewhat correct here

[charred mortar]

second part is certainly to do with industrial society in general, and that part seems fine

it's just the first half feels a bit clunky and overly wordy to me

[blazing pawn]

I assume its for like, literary purposes

[charred mortar]

that's also certainly possible

[blazing pawn]

late 19th century england was a mistake

[neat frost]

England was and still is a mistake

[long matrix]

excuse u

[steep mountain]

i think this somewhat implies

that people are controlled by this enviroment they live in because they fail to understand it

it simply dictates the demand and makes it

controls every aspect of your "needs and wants" and shifts them

causing this disturbance

if i had to analyze this more deeply

[steep mountain]

hopefully this was somewhat helpful

im sorry my literature abilities can only go so far here

[neat lintel]

btw i had tried to find english servers yesterday but almost all of them were about just foreigners' voice chatting to get better at speaking, couldn't find any good ones. and the big servers were asking for my phone number so i didn't join them. so i resorted to here today and also asked around for any good english servers.

[steep mountain]

i mean you can probably even join a philosophy or political server

[neat lintel]

yea... actually

[steep mountain]

if i had to try somewhere

[neat lintel]

philosophy servers might help

thanks for helping

[steep mountain]

im in a small philosophy server i think it might be helpful

[neat lintel]

dm me an invite or something

[steep mountain]

https://discord.gg/tyfVGY8A

hopefully sending server links is allowed
if not i apologize

tho there is some other big philosophy servers as well

hopefully you find the help you need

Sometimes when I read math, I get really scared. It'll take ages to learn it all. How do you guys deal with your fears and anxieties in math

[long matrix]

It happens at all levels

Just take things one step at a time... is some generic but not v. helpful advice

Maybe talk to people who are at the same stage of learning

that usually builds confidence --- if you can discuss things you are both stuck on

or if you can explain something someone else doesnt get and vice versa

[neat lintel]

I suppose... would be nice for things to be easier

[modest rune]

realistically you wont learn it all

luckily you very much dont have to

[magic robin]

how tf

[modest rune]

#❓how-to-get-help

[neat lintel]

Yeah, I meant when going through a book for example

Not all math

[modest rune]

its true locally and globally

i've never read a book cover to cover

probably never will unless i write one

[magic robin]

#available

[neat lintel]

I don't see any other way to learn for me, I get stuck in the details if I don't ...

[modest rune]

well, you will probably have to learn to not do that, but it takes practice and time

[long matrix]

atm the learning method that works for me is to make sure I understand the intuition behind the ideas. Including proof ideas

then come back to the nitty gritty details after (and even then I won't always look for understanding on every single bit - it's not always possible)

Like after a section or two, maybe

[neat lintel]

It's hard to be a pedantic mathematician 😫

[modest rune]

i guess so haha

[charred mortar]

I’ve found that concepts tend to sink in better some time after I’ve read about them

Amount of time for this sinking in varies significantly for me

[little vine]

I get really overwhelmed by the amount there is to learn

I've heard it said that Euler was the last person to understand all of the math of his time

[charred mortar]

A big part of that is because there was much less math to learn back then

[left hatch]

I feel like my school is behind in a lot of subjects, but mainly math cause of Covid but I'm interested in it and wanna get ahead with learning somehow.
What do you recommend I do? I've tried using sites like KhanAcademy but I feel like it doesn't contain all the stuff I should know.

[blazing pawn]

I think it's easier to give you advice if you specify what you'd like to learn

[nimble jetty]

Just curious about other's opinions, but what is your least favorite number? Plenty of people have a favorite, (mine's 8) but there's got to be some least favorites.

[mint patio]

Man I hate 6, it's too perfect

[deep mango]

I hate 91

for being composite

[nimble jetty]

I've always had a grudge against 18. It feels like a worse 12.

57 and 91 are just annoying. They look prime, you know?

[sick burrow]

57 does not look prime

91 maybe

but 57=60-3

[leaden torrent]

quality discussion guys

[long matrix]

what am i even reading

[odd narwhal]

91 does not look prime either

[long matrix]

it looks like 100-9 to me

[odd narwhal]

it's obvious a 7 fits in there

[nimble jetty]

I know they're not prime, but it's like they're so close

[odd narwhal]

in a sense they aren't, because the surrounding numbers are composite

[nimble jetty]

91 especially looks prime to me. Even numbers are easy to see, 5 are the same, and 3 and 11 have simple divisibility tests. Squares are easy to memorize (this, 49 still "looks" composite) but 91, 7 x 13, has nothing. In fact, it's the only composite number under 100 that looks prime to me.

[long matrix]

100 - 9 difference of 2 squares... jk

not easy to spot

I have internalised what 7 x 13 is though

[light needle]

i hate the number 2

literally everything fails for n=2

fuck 2

whoever invented 2 deserves a painful death

[odd narwhal]

Ah yes, the subprime number

[nimble jetty]

Oh GOD I forgot about 2

[little vine]

If anyone can field a physics question I'm curious about something. If you play a G on say, a saxophone, the G string on a guitar will vibrate in response. I know it's called resonance but I don't really understand why it works.

[hollow horizon]

2 is my favourite number because it is the date of my birth ;/

[real sigil]

I was born in pi

[nimble jetty]

I was born on 3^2 - 3^3

[winged token]

Hi, I'm a bit confused on linear operators

so I have a linear operator T from C[0,1] to C[0,1] that maps the set P: {u \in C[0,1] : u(x) \geq 0} into a smaller subset of P

im just a bit confused on the notion of maps for function spaces

[tall badge]

specifically whats confusing

[winged token]

Im a bit new to this but from what i understand T has domain and codomain of C[0,1]. which is normal, its just mapping continous function to other continuous functions. but for the second part. I'm just a big confused on the P space. Is it saying that if you apply the operator on a function in P, it's result will be an element of a smaller subset of P?

Like ill draw a picture

[tall badge]

unsure what smaller means

like proper subset?
