Idk bro you’ll find out pretty fast when you feel it happen

[mint patio]

No shot this dude is defending drunk driving

LMFAO

[solid snow]

Alcohol is a direct cause of poorer driving ability.

[river turret]

this is like saying killshealters killing pets if they cant find a home is a steryotype

man

[mint patio]

yas queen whip out the math that’ll convince em

[thick lodge]

what makes it not coincidentally correlated?

[mint patio]

[solid snow]

Because alcohol directly causes it

LMAO

[mint patio]

Alcohol is a depressant

if u think about it.... if ur nice to people and dont assume theyre stupid because of how they look..... then ur actually being inconsistent unless ur chill with drunk drivers......

It was a 2D random walk you returned father!

[neat lintel]

[deep mango]

and especially not people who use the word nihilist

[thick lodge]

why not say, I hope you have a great drive mister :3

Where else?

Do yall know?

[dense belfry]

Let E_n be a sequence of finite 1/2^n nets for your compact metric space. You can make a finite branching tree using the nets whose paths through the tree are cauchy sequences where the nth element in the sequence is in E_n. The set of paths through a finite branching tree is a cantor space, and you can define a function on the space of paths to the compact metric space which maps a sequence to its limit

[silk pilot]

Yo what this kinda sus .

[mental stratus]

😵‍💫

[rocky shuttle]

most likely to 😵‍💫

[dense belfry]

Nets and finite branching trees are good

[mental stratus]

what are finite branching trees

[dense belfry]

This but this is only 2 branching

[mint patio]

@rocky shuttle I actually forgot about this anime until you said the name

I think I watched a bit when I was younger

[dense belfry]

Imagine you have levels of the tree. A node at level n of the tree should be a sequence of n elements where the ith element is in E_i

[wet mortar]

it all makes sense now

[dense belfry]

You want to branch a node once for every element that's close to your node in E_{n+1}

So then the paths through your tree are going to be cauchy sequences

(once you've done the branching for all n)

[stark pelican]

I just learned about trees

[flint basin]

I like this because it effectively puts a limit on the cardinality of a compact matric space. Which isn't entirely surprising I guess, because compact ==> totally bounded, but still interesting

[dense belfry]

Yeah the limit is Continuum

[flint basin]

Unlike topological spaces, which have compact spaces for arbitrarily large cardinalities

[dense belfry]

Anyway do people understand this argument?

[mental stratus]

i don't 😭

[stark pelican]

You are talking gibberish to me

But that’s ok

[dense belfry]

The point is you want to represent every element of your compact metric space as a cauchy sequence of elements where the nth element in your sequence is in your nth net

And the cauchy sequence should converge 2^-n fast

[flint basin]

And because it's totally bounded and complete, these will (1) converge since cauchy, and (2) approach every point in the metric space?

[dense belfry]

Yeah

And you can represent these sequences with a finite branching tree

And the set of paths through a finite branching tree is a cantor space

Multiple paths could represent the same point

So the function which takes a sequence to its limit is a continuous surjection onto the compact space

And this gives you the desired result

(btw an epsilon net is a finite list of points so that every point is within distance epsilon of one of the points in your list)

(Existence of epsilon nets for all epsilon+ completeness= compactness)

(if you cover a compact space with epsilon balls and take a finite subcover you get an epsilon net)

[mint patio]

Yeah man I saw some shit

It’s where the voices come from

[fringe summit]

Yoinking a quick lil discussion from silly dms

Heine-Borel property seems to be equivalent to *X_fin = *X_ns

[dense belfry]

What does this mean?

Shit I'm running late to the talk I'm supposed to go to

On discretizing fluid flow and Markov modeling of the discretized model

[fringe summit]

*X_fin are the elements x such that d(*a, x) is finite for some a in X

[wet mortar]

ah

it all makes sense now

[fringe summit]

*X_ns are the elements which are nearstandard

[dense belfry]

Oh okay this is nonstandard analysis memes

Understood

[fringe summit]

Basically: bounded sequences = sequences with convergent subsequences

[dense belfry]

That's neat actually

[fringe summit]

Right, so that it doesn’t depend on your model of *X is nifty

This implies heine borel since closed ball of radius r has only ns elements, so it’s compact

[dense belfry]

Wtf

[fringe summit]

And heine borel implies it since obvious

[dense belfry]

Oh I read this as ns elements meaning you have an infinite bound on number of elements

[fringe summit]

Like 2 line proof of equivalence

[dense belfry]

Not near standard elements

[fringe summit]

Nah ns as in nearstandard

[dense belfry]

Yeah I understand now

[fringe summit]

Idk how you got that lol

[dense belfry]

I really wanted it to be true

Even though it's an inane statement

[fringe summit]

What do you mean by infinite bound

[dense belfry]

I meant like you're literally counting the number of elements in the ball

[fringe summit]

lmfao

[dense belfry]

Using infinite elements in your standard model

[fringe summit]

Well I mean you do have your aforementioned cantor space line

[dense belfry]

It would have made more sense if it had been nr lol

Where n is infinite element

[fringe summit]

yeah I don’t get it

Ah I see

I’d write that as B_N(a, x) or smth

[dense belfry]

Does it actually exist?

[fringe summit]

Does what

Well, yes

[dense belfry]

Lol

[fringe summit]

In particular that’s also an open ball

[dense belfry]

I should leave now

[fringe summit]

We know heine borel holds on X, so uhh

I wonder if you can transfer that to compactness on closed ball of infinite size

Or something

[dense belfry]

Probably not because it's a second order statement

[fringe summit]

Well we’d probably be using V(S) type stuff

[dense belfry]

Yeah you'll need to use a lot of *'s in your transfer

[fringe summit]

So we can reason about iterated power set elements first order

At least it’s certainly s-compact for uhh open cover by standard opens

[dense belfry]

Closed is second order, bounded is first order with parameters from N, compact is second order

I think

[fringe summit]

Well you can get some wacky things once you’re doing nonstandard universes hmm

Anything you’d get extra in B_N(*a) would be things that aren’t normal looking anyway

[fringe summit]

Anyway this would always be larger than you’d care for when using ultrafilters that have saturation

As in, larger than you have saturation

[hard oasis]

Uhm, would anyone know of a transformation of the whole R²-plane that collapses two points to a given third one, and leaves the rest relatively unchanged?

This happens inside a disk, the neighborhood gets altered but at infinity it doesn't do anything

So it basically collapses a V-shape of the plane into the tip of the V

I managed to do it in 1D, but it's easy x')

^
Here it collapses the points x=+/-a to the origin

[river moon]

such an overcomplicated way to write max(0, |x|-a) * sgn(x)

[hard oasis]

Lemme check!

That doesn't work

No that does I'm stupid

Thanks for that xD

But yeah, now I'd like this on the plane

[hard oasis]

Even something that resembles vaguely this, and collapses three points to a common fourth one is fine!

Okay I'm gonna do something crude:

1. map a triangle to a disk
2. apply the map z->z*|z|^n for larger and larger n, except do id outside the disk
3. profit?

[alpine kindle]

just do it

[hard oasis]

?

[alpine kindle]

for some a,b,c let f : R² → R²
f(a) = f(b) = c
for x ≠ a,b : f(x) = x

[hard oasis]

Yeah well I didn't say it but I'd like something continuous obviously...

I'm not dumb enough to not have thought of this

[alpine kindle]

oh you don't mean completely unchanged?

[hard oasis]

What I'm searching for is some (continuous) transformation that 'pinches' three points together

[fringe summit]

They seem to want it to be closer to normal as you get further out

[hard oasis]

Yes!

[fringe summit]

But certainly not in the disk itself

[fringe summit]

.

Their 1d one is asymptotically the identity tho

[alpine kindle]

let D be the closed disc with a,b,c on the boundary, let k be its centre, and let r be its radius
define f as such
for x in D, f(x) = 0
for x not in D, f(x) = (x-k)*(d(x,k) - r)

basically squeezes a disk to the origin

@hard oasis

[hard oasis]

Yeah, it works x') I mean, it's a discussion channel so I didn't go into details, but I'd need something less crude
It's okay though, I'm trying to make this method work, I think I'm onto something!

[alpine kindle]

my one is just the generalisation of your original one

for 1d

kinda

modulo some translation

[wicked flower]

I was about to say if treating points as vectors is ok I think $f(x) = x +(p-x)*max(e^{-||x-x1||},e^{-||x-x2||})$ works, but I'm not sure that's continuous

Where p is the point you want to converge to, and x1,x2 are the points you want to move to p

instead of each point being like

the set of points not equidistant from a point?

[cold rivet]

yes

a spiral?

[jagged forge]

so just the set of points not on the circle

[cold rivet]

yes but the mathematical opposite

i guess im looking for something abstracty

[jagged forge]

I mean that seems fairly mathematical to me

opposite of set X = the set of things not in X

[cold rivet]

what other definitions for a circle exist

like there are 2 explanations for exponents and stuff

which ends up making the paradox of 0^0

the 2d curve with constant curvature?

maybe

to be honest i dont know what answer im looking for

[flint basin]

I mean those aren't really related to circles but uhhhh

[cold rivet]

both are

[jagged forge]

how

because sections of them are circles?

[cold rivet]

well

a psuedo sphere is like

a reverse circle

[flint basin]

what does that mean

[cold rivet]

and gabriels horn is like half of that

they curve inwards

[jagged forge]

no it’s like a reverse sphere

[cold rivet]

well yes

so make it 2d

[jagged forge]

because it has negative constant curvature I guess?

[cold rivet]

thats what i was looking for yes

negative curvature

[jagged forge]

well you can’t even have negative curvature in 2d apparently

actually you can

but a curve of negative constant curvature in 2d is still a circle

do you guys ever experience this: rarely while falling asleep or before waking up, i hallucinate the stuff i would be seeing. it doesn't exactly come into vision, i just have a strong awareness of those objects in my field of view. i know it's not me actually seeing those stuff because sometimes i open my eyes and it turns out some stuff was in the wrong place.

[loud snow]

Yes

Im not sure how common this is but it happens to people

[sonic sentinel]

o.O

how accurate is my description to your experience

[loud snow]

Happens all the time to me

Like last night

I think you have to be somewhat aware of this happening to recognize it

Because id say it happens to me everytine im falling asleep

But sometimes im too tired to become conscious again and snap out of it, so i fall asleep

[split oak]

These are called hypnagogic(while falling asleep) and hypnopompic(while waking up) hallucinations.

They aren't too uncommon

its prob. useful to people who need to talk about it over and over

But its not as vivid

[sonic sentinel]

no color, no brightness, just depth
if i had to make an artistic representation of it i'd use a black background and each object would have faint blue edges

[loud snow]

Maybe those are just imaginations

[sonic sentinel]

how hard do you think lol

[loud snow]

This is rare tho

I can’t remember last time it happened

When I was rock climbing it would happen sometimes

I wouldnt climb but I would think about what I would need to do without moving but im p sure its just an imagination

Not hallucination if there is difference

[sonic sentinel]

lol the wikipedia page for hypnagogia mentions rock climbing by coincidence

[loud snow]

Wtf?

[sonic sentinel]

For example, Robert Stickgold recounts having experienced the touch of rocks while falling asleep after mountain climbing.

[loud snow]

Oh okay then this happens to me too often

It is rarely cohesive though

Im talking about while awake but tired/not moving

[glad phoenix]

How would you describe yourself in 3 words

[sonic sentinel]

smart, beautiful, talented, and humble

||^stolen joke||

[alpine kindle]

young, popular, talented

i am a friend, a daughter, a sister

[sonic sentinel]

i really don't know how to answer this question tbh

if its just like looking at a specific section of my life it'd be answerable, but not on the whole

[glad phoenix]

Oo these are positive ones! I am glad

[glad phoenix]

Hmm, it’s more like about the personality as a whole. Or what section would you recommend

[fringe summit]

“I demand bread”

[glad phoenix]

What kind of bread

[fringe summit]

Now you’re getting it

[sonic sentinel]

how i view myself at school? uh funny, and now i realize i literally cannot come up with any other personality trait (not just limting myself to positive ones) that you can't argue for either side

[glad phoenix]

I feel like I might be, but not sure

[fringe summit]

The first question wasn’t why but which kind

[glad phoenix]

Oh that’s a good example. At school. Do you mean you would say the 3 as you already said?

[glad phoenix]

Exactly… you can mean so much by a bread, it might not even be a bread

[sonic sentinel]

another seems to be "indecisive"

[glad phoenix]

Oh, about particular things or overall

[sonic sentinel]

the "smart, beautiful, talented, and humble" was a joke

[glad phoenix]

Oh no, why does it have to be a joke

[fringe summit]

Furthermore it’s a demand

[sonic sentinel]

cause its four words, and the person who said the joke is presumably not humble because they had to go over the three word limit just to fit in humble in there

[glad phoenix]

People usually don’t demand a bread so that’s why I thought you mean something deeper by the statement

[glad phoenix]

Oh haha, yeah. Why are you not humble

[sonic sentinel]

also "talented" seems to work pretty nonambiguously

funny, indecisive, talented; i have gathered enough words

[sonic sentinel]

never said im not humble

to the person who just so trued me

[fringe summit]

yum yum, plus demanding tribute

[sonic sentinel]

may God forgive you 🙏

[glad phoenix]

Mhmm

[tame egret]

David, David and ||David||

[tame egret]

lol

[glad phoenix]

Oh you must like your name

[tame egret]

yes

[tame egret]

I just texted that because nothing came to my mind
lol

[glad phoenix]

Haha, why don’t you think of your characteristic traits

[tame egret]

oh um laziness?

[glad phoenix]

Maybe like in a family, how do you behave there

[glad phoenix]

Haha, yeah, could be

[tame egret]

lazily

[glad phoenix]

Haha.

[tame egret]

and I hate economics and fish

does that count?

[glad phoenix]

Oh, that’s interesting. Yes it certainly does

You hate to eat fish ?

You hate economics at school?

[tame egret]

No I hate learning about fish 🐟 I'd rather learn phishing

[tame egret]

partly

[glad phoenix]

Hmm, why don’t you find interest to learn about fish, are they boring to you?

[tame egret]

yes

[glad phoenix]

Maybe you learn just about the ones that live in ponds? If you search on YouTube about the most interesting fish, you will be surprised how amazing they are

[tame egret]

maybe but i doubt 🤷‍♂️

[glad phoenix]

Yeah I hear you. I like to watch documentaries of the sea world! So I have some confident you would find at least one enjoyable to learn about

[tame egret]

r u indian?
just asking

[glad phoenix]

Hmm I am not, are you

[tame egret]

no

[glad phoenix]

Why Indian

[echo tundra]

Did you mean fishing cause phising is a criminal offence?

[tame egret]

yes

[tame egret]

name ig

[echo tundra]

Huh Sabina is not an Indian name though

Not a common one at least

[glad phoenix]

Oh, no I am from Europe.

However David is common in Europe too, in Asia like Israel too, in America I guess as well. So I don’t know

[glad phoenix]

Maybe he knows some

[tame egret]

oh

[glad phoenix]

Mhm

[tame egret]

discussy is dead xb

[glad phoenix]

Everyone is working

Or sleeping

[tame egret]

ok

[glad phoenix]

Why do you have time to be here

[tame egret]

I read from twelve to six and use discord.py from 6-9 while I chat

[glad phoenix]

Oh what do you read? What’s discord.py

[tame egret]

I study math physics chemistry english geometry biology

discord.py is package in python (discontinued) used in aking discord bots

[glad phoenix]

Wow, how could you call yourself lazy when you have such a great time management

[glad phoenix]

Thank you for explanation

[tame egret]

because I am

[tame egret]

np

[glad phoenix]

I thought lazy people can’t get to work, or learn

But you read from twelve to six..

[tame egret]

no

[tame egret]

there are grades of laziness from 0 to richard waterson

[glad phoenix]

Haha. Do you watch animated movies ?

[tame egret]

YEAH somtimes

[glad phoenix]

Is the one on your profile important to you

[tame egret]

yes

[glad phoenix]

That’s nice… because of his character ?

[tame egret]

yeah

[glad phoenix]

Is he positive or negative character

[tame egret]

middle

[tame egret]

@glad phoenix his name is senku

[glad phoenix]

That’s not a bad name. What do you appreciate the most about his character

[tame egret]

his Intelligence

[glad phoenix]

Mhm. That’s actually a nice thing to “desire”. How can one become intelligent?

[tame egret]

acqusition of knowledge

[glad phoenix]

Yes that’s actually true! What’s the best source of knowledge

[tame egret]

GOD

[glad phoenix]

Mhm yeah, that’s a good answer. Do animated characters believe in God

[tame egret]

Idk they do not exist in the real world so I ... Idk

[glad phoenix]

Yeah.. I saw many people trying to wear clothes like them. Can be dangerous to watch too much of it?

[tame egret]

yeah

[glad phoenix]

Yeah I also think so

Once I watched an anime, I did not know it before, but I was too emotional because the way it’s done is just interesting so I had to stop

[tame egret]

oh

[glad phoenix]

Yeah..

[tame egret]

Dr.stone is nice tho

[glad phoenix]

Oh I don’t know that one!

What time do you usually go to sleep

[tame egret]

why did you ask?
not to be rude just asking

[glad phoenix]

Oh because soon I go sleep haha and wondered what time other people can be falling asleep

[tame egret]

oh 11pm

,ti

[fathom swallow]

The current time for ishigamisenku_ is 08:54 PM (WAT) on Wed, 16/08/2023.

[tame egret]

2+ hrs left

[glad phoenix]

Ooh, yeah me too, but now it’s 10pm and I am always feeling sleepy

[glad phoenix]

Oh you can use discord “password” well

[tame egret]

nah i just saw someone doing that L

[glad phoenix]

Oh haha, wonderful!

[tame egret]

gn then

[glad phoenix]

Thank you! Gn to you too

[alpine comet]

U mean cosplay? Yeah, it's a thing

[neat lintel]

@split pawn how do i draw vectors in desmos?

would it just use point slope formula and limit the domain?

?

[solar hawk]

I have a thing for it

[long matrix]

[silent grail]

had anybody have heard off AMC 8?

[solar hawk]

Naturally

Everyone has

[mint patio]

I use parametric equations and limit the domain

But both work

[neat lintel]

AMC theaters?

Like

the 8th AMC theater

https://www.amctheatres.com/movie-theatres/houston/amc-houston-8

[split pawn]

use like A+t(B-A)

[flint basin]

How does one stick to a schedule? I have lost all resemblance of a schedule in my daily life over the summer and I ought to get that shit together before uni starts again lol

[neat lintel]

is position always notated as $$\vec{r}$$ when talking about vectors?

[fathom swallow]

One person

[zealous garden]

no

but often

[jagged forge]

do you wake up and go to sleep at roughly the same time?

[flint basin]

Give or take 2 hours yeah

[river moon]

I color the days in my excel calendar in which I was roughly following my schedule makes me feel bad seeing a streak of uncolored days

[fringe summit]

I would also like to know

[jagged forge]

idk u guys were in school longer than me lol

but at the beginning of the semester I’d print out my class schedule, and plan out what time to wake up and eat, as well some important activities like studying

it doesn’t all have to be scheduled but like

as long as you have a skeleton for your day I guess. that’s how I did it

but that’s also slightly pertaining to “academic planning” which I’m not sure whether or not that’s your goal

[neat lintel]

hello humans

[flint basin]

Yeah that's what I was thinking of doing roughly, like planning which books/classes I'll work on throughout each day
Otherwise there's no chance I'll be able to keep up with everything I'd like to do next year lmao

[flint basin]

I have gotten this far by just winging it and that will not work going forward lmao, I need structure

[neat lintel]

Hey, how are you?

[ocean harbor]

in high school?

[jagged forge]

no I dropped out of college in the middle of undergrad and they are in grad school or preparing for it

[ocean harbor]

oh I see

[zealous garden]

Hm I see

[jagged forge]

I guess there is kind of a spectrum when it comes to winging it. Some classes i never studied, some classes I just needed to make sure to plan to review it for 15 or 30 minutes on the same day before class. but that was for easy stuff like undergrad humanities where you just have to memorize a bit. for more in depth classes I guess you really need to plan out blocks of time to “study”, like for real

for me, because I studied music in undergrad, the closest thing I had to that was practice sessions and music analysis, which was something I definitely had to plan to make time for every day. but I didn’t necessarily plan every last detail. at the beginning of practice I would just look at my upcoming deadlines and see what needed to be ready by next Thursday etc.

trying to plan out every last detail in advance could potentially be tiresome, and you might not even know what you need to study before next week. Idk how grad school works or how structured it is though. I assume some of it is a bit more open ended than undergrad?

that’s like more of a last resort to me

of course there are long term projects and you need to think about that more on a rolling basis though

[flint basin]

Yeah that's fair that it definitely is case by case for the class. I guess I'm just concerned that my poor habits will catch up to me or that I'l laze out of doing stuff
I definitely will not keep up with it if I micromanage, I just need to figure out the right balance that (a) is productive and (b) not overbearing

[jagged forge]

indeed, I sort of wonder if it’s worse to overshoot or undershoot here lol

probably overshooting a bit is better

[fringe summit]

I laze about too much

[flint basin]

I can no longer talent my way through classes

[jagged forge]

what’s the hardest math class you talented through in undergrad?

[flint basin]

uhh I mostly talented through real analysis 2. Complex analysis 2 was a bit less talent, that shit confused me for a while lmao

[jagged forge]

actually what year are you in, are you just starting grad school?

and there are 2 analysis classes for each of real and complex? damn

[flint basin]

last year of UG

[flint basin]

yeah mine had RA1 just real functions, RA2 general metric spaces. CA1 mostly basic holomorphic functions and CA2 stuff like harmonic functions, univalent functions, montel/schawrz/riemann mapping theorems, etc

[jagged forge]

man @fringe summit was making fun of me cuz I didn’t know darboux’s theorem I only took up to linalg in college

I did like 3 chapters of baby rudin on my own time

[fringe summit]

I havent taken a good CA class

[jagged forge]

which is to say, you took CA but it was bad?

[fringe summit]

No I took baby intro class

[jagged forge]

ah

[flint basin]

I had to google what darboux's theorem was ngl

Didn't know from just the name lol

[jagged forge]

consequences of talent lol

[flint basin]

I say this and then I see HS students doing p-adics and quadratic forms and shit

[fringe summit]

i hate theorem names

[fringe summit]

real

[flint basin]

(------)'s theorem

[fringe summit]

Ilum doing p-adic analysis but couldn't handle a determinant

[flint basin]

I'm not thinking of Ilum lmao, I'm thinking of someone I've actually met like that

But also Ilum

[fringe summit]

I'd say plas but

[storm sage]

Hey no making fun of users

[flint basin]

friendly jestering. We all have our moments

[fringe summit]

we just bein a lil silly, theyre gonna be way more successful than I ever could

[mental stratus]

still sick 🤧

[jagged forge]

that’s cuz u study cursed set theory instead of interstellar travel

[flint basin]

[mental stratus]

guess who else would have been in last year ug rn

[fringe summit]

honestly yeah

[mental stratus]

[latent edge]

I think I did CA more than RA

I'm a CA addict

[jagged forge]

real analysis can’t hurt me

[flint basin]

See, I thought I liked analysis because of my RA2 class, but now I think I just liked the topology aspect lmao

I guess I'll see in functional analysis and measure theory

[jagged forge]

topology was indeed my favorite part of baby rudin, at least the little of it that I did (though I think it was mostly metric spaces?)

functional analysis is based tho. I mean how cool is it to just take a holomorphic function and apply it to a linear operator like the derivative

(I don’t have the knowledge to prove that that’s valid but apparently that’s a thing)

[neat lintel]

hey! can sb help me with calculating arcsech(x)?! i have calculated:

What’s the worst dream you’ve ever had?

[vale trench]

went naked to school

[solar hawk]

smh. youre gonna get copyrighted for that dream

[vale trench]

that is the only worse one i remember

[vocal vessel]

Isn’t that more of a nightmare for everyone else?

[echo tundra]

wot

[solar hawk]

😠

[echo tundra]

[flint basin]

[pearl moth]

i had a dream once where i was pregnant but had to hide this from the hospital because they'd be mad at me if they found out

that was pretty weird

i've also had the "oh fuck i forgot to go to class for an entire semester" dream more than once including fairly recently and i haven't been a student for over 25 years

i also had a dream onec where i managed to get a master's degree that felt so real that it took me a while to convince myself that i hadn't actually done so

[surreal sapphire]

i never forgot

i did it deliberately

[pearl moth]

oh sure i've skipped lots of classes, but that's not the same as "what? i signed up for that class? how?"

there was even one dream where i somehow managed to go to medical school for a whole year before th dream ended

which is wtf i never wanted to to go medical school

[narrow peak]

Guys I am going to run 5 km after leg day tommorow (Will I hurt my legs or can you still do it?)

[surreal sapphire]

5km is not a lot

[narrow peak]

Ok so I be fine th

anks

[tame egret]

lol

[woven whale]

Our pe teacher made us run 6.5 km in 30 mins

No water

[surreal sapphire]

thats not much either lol

body is also surprisingly good at conserving water

just drink before and/or after

[woven whale]

Not if you’re as unathletic as me

[narrow peak]

same i dont run often i suck at cardio

[surreal sapphire]

hmm

well, its not inhumane after all

though in the direct sun for long time might be bad unrelated to water consumption

its so hot this weekend and i want to walk 60km 😦

[mental stratus]

not as sick anymore

[tight comet]

[small dust]

i am so happy for you

[prisma swallow]

6.5km in 30 minutes is kind of difficult

I have a hard time believing that the average mathematician can do 6.5km in 30 minutes

Therefore, I don’t think loch would be able to do it(by statistics)

[surreal sapphire]

i actually dont know if i can

i dont really do running

i walk with weight of ~12kg and i do 7km/h on average for multiple hours

i extrapolate and say 6.5km in 30 mins is easy

[burnt dune]

the moment i started learning AG my hair is getting thinner

is this a sign

i am him

[flint basin]

[burnt dune]

bro thinks he is him

[zealous garden]

Time to learn AG

[tame egret]

@zealous garden

[woven whale]

damn bro you're thin

[surreal sapphire]

*extra weight

[loud snow]

I also walked home from school in HS

[surreal sapphire]

but for me it was uphill both ways

with snow.

[loud snow]

I forgot to mention im terminally ill

And walking is an olympic level feat due to my condition

[wet mortar]

yo

what colleges have good mathematics?

and like

reasonable tuition

[neat lintel]

PragerU

[cold rivet]

my act score is good enough

[neat lintel]

look at their math department websites

[cold rivet]

vanderbilt is like my school of choice, but its very… selective

[neat lintel]

see what classes they offer

[cold rivet]

how do i know its good tho?

[neat lintel]

pretty great for medicine

[cold rivet]

some colleges looked really good, but certain departments were lacking.

according to students

[neat lintel]

it's good if they offer a variety of electives

[cold rivet]

so many decisions

like for colleges not electives

[neat lintel]

and look at undegraduate math programs

[cold rivet]

alr

[neat lintel]

My college is okay at math but doesn't have a lot of programs for math ppl

Ik unis like Tufts has math modelling contests

You could try Boston Uni

They're great at comp sci and math

[cold rivet]

what math degrees should i be going for?

like physics

[cold rivet]

and i can do computer science but its fairly difficult

[neat lintel]

Mine is just math math

You get to pick your math elective classes

[cold rivet]

like literally mathematics lol

[neat lintel]

And concentrate in an area

[neat lintel]

yeah like there's a math major

which isn't applied or pure

Just math

[flint basin]

UG generally you don't specify beyond maybe applied or pure

[neat lintel]

Yeah unless you're in waterloo

[flint basin]

You may, of course, have specialized interests in the courses you take, but this distinction is not made in your degree usually

well that's a UW moment

[neat lintel]

they have a whole degree type called bachelors in math

[cold rivet]

none of this shit makes sense

[neat lintel]

I looked at their classes

Looks interesting but

the whole BMath degree is kinda bs

Like it was unnecessary

Upside is a huge set of classes to choose from

[cold rivet]

what can i do with a degree

[neat lintel]

work in the industry as a consultant or software engineering

Those are probably the popular routes for math majors

Or go to gradschoo

[cold rivet]

what about west point?

its a military academy

[neat lintel]

Get a masters in data science

[cold rivet]

but like

[neat lintel]

From CMU

and become

Invincible

[neat lintel]

oh that

[cold rivet]

is that a good idea?

[neat lintel]

CMU has the best CS gradschool in the US

THE BEST

[cold rivet]

thats that one college in pennsylvania right

[neat lintel]

so as good as it gets if you can get in

yes

[cold rivet]

maybe i could get a dual major with something math related

idk if i can afford a masters unless i get like a full ride

[neat lintel]

i'm double majoring in cs and math

they go really well together

[cold rivet]

C in athletics B in math

[neat lintel]

[cold rivet]

i got an ACT of like 33

and it might be a 34/35 soon

probably a 34

[neat lintel]

Nice

[cold rivet]

what GPA would be good?

[neat lintel]

3.5 or up is solid

[cold rivet]

aight i got like a 4.1 aiming for a 4.2

[neat lintel]

3.9 if you wanna get into competitive ones

[cold rivet]

wait unweighted

[neat lintel]

unweighted I meant

[cold rivet]

uh oh

[neat lintel]

[cold rivet]

let me check it unweighted

ill have to check later

its probably like a 3.6

pr 3.7

but aight

if i can i might send an application

[neat lintel]

good idea

[cold rivet]

ok gn

[neat lintel]

[fathom tendon]

Ugh I've finally hit a math course where I don't understand a proof (HS Linear Algebra) and I've been trying to get it for probably about 2 hours now and I've tried to just like give up and move on but I can't stop thinking of the proof and just going back to it and staring at it

How do I just like move on from the problem, because I can't focus on my other homework without having finished the proof

[jagged forge]

damn I wish my high school taught linear algebra

did you make any progress or are you just staring at the page at this point

[fathom tendon]

I've made like 3 steps in and have been staring at it

occasionally trying to do something different but it never goes anywhere

[jagged forge]

do u mind sharing the proof? I’m curious

[fringe summit]

Or the problem

[fathom tendon]

Given 3 points (x_1,y_1) (x_2,y_2) and (x_3,y_3) that all lie on the parabola ax^2+bx+c. Show that the coefficients a, b, and c are solutions given that the augmented matrix is
Row 1: x_1^2 x_1 1 y_1
Row 2: x_2^2 x_2 1 y_2
Row 3 x_3^3 x_3 1 y_3

it wouldn't let me post an image but thats the problem

also i dont know latex so thats a rip lol

[jagged forge]

oh that’s neat

[fathom tendon]

and its our first day so like we definetly are starting off running lol

[jagged forge]

do you know the relationship between an augmented matrix and a system of linear equations?

[fringe summit]

I mean, literally speaking, you do have that ax_1^2 + bx_1 + c = y_1

[fathom tendon]

i know that its just the addition signs missing

[fringe summit]

Since they lie on the parabola right

[fathom tendon]

yeah

[fringe summit]

So clearly they work as solutions

[fathom tendon]

i have it in my proof where im at that the rows are equal to that represenation of y

[fringe summit]

In that plugging them in works

[fathom tendon]

I don't know how to show that because they are coeffecients in the y represenation that it means they are solutions

[fringe summit]

well, applying the square on the left to [a, b, c] does get you [y1, y2, y3] by definition of the parabola yes?

And the points chosen of course

[fathom tendon]

uhh maybe

I think I may have just completly drained my math battery after staring at it for 2 hours and now understand nothing lol
