jesus a bit of a step up

[south rain]

Idk what log does

[errant kiln]

:/

[sleek wing]

it's basically x^2+x = 27

that's the one

had to go up each power of 3 but I got there

[errant kiln]

0.0

[sleek wing]

powers of 2 go

1 2 4 8 16 32 64 128 256 512 1024 2048 4096 8192 16384 32762 65536 131072 242144 uhhhhh

[south rain]

Can you give an easy one

https://cdn.discordapp.com/emojis/847288107161747457.png?size=64

[errant kiln]

Colemak doesn't have the powers on altgr2,3 like the german keyboard. I appreciated those.

[errant kiln]

That's quite easy.

[thorn brook]

well this one is not that hard

[sleek wing]

non-integer roots = bit annoying

do you know the quadratic formula?

[errant kiln]

I just used random numbers, tbh.

[south rain]

Lemme try

[south rain]

-3?

[thorn brook]

In Sweden we use a different formula. If we have $x^2 + ax + b = 0$ then in school we learn that $x = -a/2 \pm \sqrt{ (a/2)^2 - b }$

[errant kiln]

hm

[south rain]

Oh wait

[fathom swallow]

Tokidoki

[sleek wing]

that's the quadratic formula lol

[thorn brook]

which is weird since everyone else learn the abc formula

[sleek wing]

just with a = 0

[errant kiln]

We do the same, but we say p.

[south rain]

I'm referring to this

[thorn brook]

yeah it is but a lot of countries learn the abc formula

[sharp mulch]

[sleek wing]

don't you 🤨 I'm right

[paper nexus]

what the fuck

[errant kiln]

[sleek wing]

I meant a in the original formula

you know, the CORRECT one???

[errant kiln]

no

a=1

[cold needle]

hmm

[sleek wing]

oh my goddd they're homomorphic I don't careeeee

[errant kiln]

what does that have to do with solving the quadratic?

[paper nexus]

how do you know when youve truly understood something in math

[sleek wing]

they're going from the original thing you gave

[errant kiln]

when you don't get an f on your exam

[thorn brook]

Maybe try to explain it in simple terms?

[sleek wing]

when you can explain it confidently

[paper nexus]

alrighty

[south rain]

Idk I mean idk what log does so I'm looking at that image and trying to understand

https://cdn.discordapp.com/emojis/586031051068014612.gif?size=64

[errant kiln]

If you get most of the practice problems right, you probably understood it quite well.

[sleek wing]

log_x(a) = b means x^b = a

[errant kiln]

Logs are quite difficult if it's the first time you're hearing about them.

[thorn brook]

if it's too confusing then just use this as your starting point

[south rain]

Yep but I kinda understand now I'm trying to think of them as function for coding
But rn I'm trying to figure out what x is

[paper nexus]

i always question my understanding when there's a difficult problem that i cant do

[errant kiln]

what topics are you referring to?

[paper nexus]

right now, proofs.

floor function proofs and countability proofs

[errant kiln]

0.0

[paper nexus]

the former im still absolute shit at

[thorn brook]

just get a shit ton of proof based exercises and do them all I guess?

[errant kiln]

Proofs are just proofs. That doesn't necessarily mean you don't understand the topic.

[south rain]

It was 3

https://cdn.discordapp.com/emojis/586031051068014612.gif?size=64

I wrote -3

[sharp mulch]

[south rain]

Oh wait

[errant kiln]

x^2+x = 27, x !=3

[south rain]

Nvm

[sleek wing]

x isn't a whole number that's why I said the question was annoying

[deep mango]

Proofs are just proofs

[south rain]

Lemme figure it out myself

[paper nexus]

i do understand what the functions are obviously, but the way they prove shit sometimes

[errant kiln]

yes

[errant kiln]

Proofs take practice, I struggle with most proofs as well 0.0 I get barely 50% right.

[paper nexus]

i have to SEE someone solve something in a new way before i apply it on my own

like i cant think of a creative proof on my own

[errant kiln]

While you might fail at most, doesn't it feel very good once you figure out one on your own? xD

[paper nexus]

it does

very much so

[errant kiln]

So just keep trying.

[paper nexus]

im trying

[south rain]

I can't figure out what factors to 27

https://cdn.discordapp.com/emojis/586031051068014612.gif?size=64

[vast surge]

$3^{3}=27$ @south rain

[fathom swallow]

Bannanachair Monarch

[south rain]

But (x²+x) = 27

[errant kiln]

You can't factor that, humanly.

[south rain]

I'm trying to find x here

[sleek wing]

yeah

[errant kiln]

I picked bad numbers.

because I am cool

[south rain]

https://cdn.discordapp.com/emojis/742908211224641657.png?size=64

[sleek wing]

but that's how you'd get to that from log_3(x^2+x) = 3

[thorn brook]

use the quadratic formula. If you don't know what that is then maybe another exercise must be given I guess?

[vast surge]

Given $ax^{2}+bx+c=0$, the quadratic formula states that $x=\frac{-b\pm\sqrt{b^{2}-4ac}}{2a}$

[south rain]

Gib problems

[fathom swallow]

Bannanachair Monarch

[south rain]

[errant kiln]

That was the first step, if you are confused by that.
$$\log_3{(x^2+x)} = 3 \Leftrightarrow 3^{\log_3{(x^2+x)}}=3^3 \Leftrightarrow (x^2+x)=27$$

[vast surge]

The quintic formula is way more fun, no thanks to Niels Abel

[thorn brook]

how about this one: x² - 6x+8=0

[fathom swallow]

Master of Mental Maths

[south rain]

...

[thorn brook]

but this one factors nicely

[vast surge]

Look for two numbers whose product is 8 and whose sum is -6 and you'll have an easier time

[sleek wing]

just use this

[south rain]

x²-4x-2x+8 = 0
x(x-4) - 2(x+4) = 0
(x-4)(x-2) = 0
--- what I know ^
X = 4 or 2

[errant kiln]

You can get the second solution as well.

but nicely done.

[south rain]

Actually after the --- i didn't know what to do next but I just mentally did it and thought 0*x = 0

[errant kiln]

x=2 and x=4

That's how it works though.

[south rain]

Oh yeh

I was able to solve the thing on my own

https://cdn.discordapp.com/emojis/844413204087308324.gif?size=64

[errant kiln]

Ax=0 if and only if either A is 0 or x is 0.

[south rain]

Could I say

X = 4 or 2

[errant kiln]

I'd say AND, not or.

but that's weird, too.

[paper nexus]

alwyas been confused about the and or thing

[vast surge]

This is exactly the correct method.

[paper nexus]

teachers in school never explained it fully

[errant kiln]

well, x can't be 2 values. so say
$x_1=4$ and $x_2=2$

[paper nexus]

but it isnt required that x has to be both

[south rain]

https://c.tenor.com/6gjxzAbR11MAAAAM/shy-anime.gif

[paper nexus]

it can just be one and multiply the other by 0 to get 0

[fathom swallow]

Master of Mental Maths

[paper nexus]

so why say and ?

[south rain]

I think or is better

https://cdn.discordapp.com/emojis/788882232441307154.gif?size=64

[paper nexus]

and implies both have to be true or none at all

in school i averted this by just using a comma

[lean robin]

does anyone speak lithuanian pls help

[paper nexus]

Do you at least drink

water

[hollow ginkgo]

How are you still alive?

[umbral oxide]

Yes

[hollow ginkgo]

So you lied?

[umbral oxide]

I don't drink alcohol

[vast surge]

In all seriousness though I require alcohol to live.

[hollow ginkgo]

You said you didn’t drink at all.

[umbral oxide]

Thats a lie

[hollow ginkgo]

Ok

[vast surge]

It's great for my mental health.

[umbral oxide]

Because I said that diet Sprite is better than root beer

[lean robin]

anyone speak lithuanian?

[hollow ginkgo]

I drink exclusively water

[vast surge]

There was someone a little ways up who was asking the same question; maybe they can help you.

[lean robin]

i cant find them.

[vast surge]

I think their name was @lean robin

[lean robin]

:/

[neat lintel]

Why so mean to someone asking for help?

[vast surge]

Also I'm sure most people in Lithuania speak Lithuanian

[vast surge]

Honestly it's hard to convey tone on the internet. This was intended more as light joking than cruelty.

[leaden torrent]

of is a weird english word

its only 2 letters and yet neither of them represent the correct pronunciation

[cold needle]

[tacit sundial]

dont do me like this

[leaden torrent]

(mind, its correct pronunciation in a sentence is with a schwa, which doesnt really have one standard english symbol)

(but o for schwa is rare compared to e or u)

[toxic schooner]

schwa?

[leaden torrent]

the lazy vowel sound that occurs almost always in unstressed syllables

like the e in father

or the a in about

or the unwritten vowel between th and m in rhythm

IPA /ə/

[toxic schooner]

namington took linguistics classes iirc

[toxic schooner]

ok that makes sense

lmaooooo she replied too. massive w

[astral marsh]

yep

[pale orchid]

nami's great passage arc

[sick burrow]

Have there been any cases of people discovering a flaw in what was once a commonly accepted and reasonably important proof?

Especially if they found the flaw long after it was originally published

What happened?

From the Wikipedia article, it sounds like the issue is they just got sloppy

But I guess maybe that still answers my question

[velvet dagger]

It's more than you think

They proved theorems which were incorrect

[sick burrow]

yeah I saw from the wikipedia article

[limber thunder]

also happened a ton with early real analysis https://mathoverflow.net/questions/35468/widely-accepted-mathematical-results-that-were-later-shown-to-be-wrong/

[velvet dagger]

Yeah early analysis was weird because people weren't very clear on definitions

I think Fourier's claims were very ballsy and it reached a point where people were like aight hold up we gotta be clear on what's a function etc

So I know someone at some point attempted to prove FLT assuming Z[\zeta_n] was always a UFD

And the incorrectness of this proof has a lot to do with the eventual development of algebraic NT

I wonder how long it took for someone to point out the flaw in the proof?

[sick burrow]

oh yeah I heard about that

well I forgot the specifics, but I remember hearing there was some erroneous proof of FTL where the mistake was assuming some ring was a UFD when it wasn't

[surreal sapphire]

wikipedia says

This gap was pointed out immediately by Joseph Liouville, who later read a paper that demonstrated this failure of unique factorisation, written by Ernst Kummer.

what a weird sentence though

"who later read a paper"

[jovial ember]

Coomer

[last oxide]

[thorn brook]

sherlock holmes

[dense belfry]

Yeah communication was hard back then

I remember reading that Turing proved the CLT for his undergrad thesis cause he didn't realize it was already a theorem

And that was in the early 20th century when communication was a bit easier

[sick burrow]

CLT?

[sleek wing]

central limit theorem :Trollface:

[sick burrow]

Ah

[sleek wing]

I think anyway

[leaden torrent]

smh i proved CLT in my third year of undergrad

why arent i as famous as turing

is this the gay agenda at work

[neat lintel]

Yeah

I can personally vouch for it

[dense belfry]

He rediscovered the statement of CLT and proved it without knowing about it

[leaden torrent]

so youre saying academia is rewarding ignorance now?

wow.\

we truly do live in a society

[cinder zephyr]

CLT is cool

[dense belfry]

We do in fact live in a society

[sick burrow]

At least he didn't do anything really stupid like rediscovering the trapezoidal rule

And then publishing the result in an academic journal

[cinder zephyr]

lmfao

I remember that

[dense belfry]

Honestly in that scenario the stupidity is more on the part of the journal than the publisher

[cinder zephyr]

For sure

[sick burrow]

I mean it's on both but more on the journal, yeah

[neat lintel]

Oh, that was funny
Biology

[leaden torrent]

and the like

80 citations it got

before https://europepmc.org/article/med/7677819 was published lmao

sorry, not 80 citations

200

The validity of each model was verified through comparison of the total area obtained from the above formulas to a standard (true value), which is obtained by plotting the curve on graph paper and counting the number of small units under the curve

apparently the old technique was to print out the graph and cut out the area

and weigh it

[sharp mulch]

[leaden torrent]

which sounds dumb but at least that objectively works

within an error

[sharp mulch]

Is this about biologists discovering integration

[leaden torrent]

y

[sharp mulch]

The only reason a bio paper would be linked here

[broken scaffold]

*cuts out spike function*

[last oxide]

graph the cantor indicator in a piece of paper

[leaden torrent]

honestly now i want to ask students as a problem for like

bonus points

on a calc pset

come up with an interesting, nonstandard way to estimate area under a curve. your method doesnt have to be rigorous, but it shouldnt look like something we did in class

and see how many come up with some physical method

a la print it out and weigh it

[modest rune]

inb4 someone invents monte carlo

[leaden torrent]

hey that works too

[sharp mulch]

Monte Carlo is fancy box counting

[leaden torrent]

randomly sample points, see how often theyre under your curve

continue for a really large number of points

[broken scaffold]

3d print graph as a cup and drink water from it

(estimate based on how thirsty you feel after)

[compact tartan]

find the center of mass by hanging and see how high it is from the x axis

wait does that work

that probably calculates something else

[sharp mulch]

It calculates the center of mass

[compact tartan]

that's like the integral of f^2

modulo scaling

[deep mango]

Evaluate the function at a randomly chosen point. Multiply by the length of the interval.

Perhaps it will take you many tries. But you will be right eventually if your function is not too terrible!

[leaden torrent]

but how do you verify correctness

[broken scaffold]

ask your TA

[deep mango]

correctness? i thought we were finding estimates.

i've provided you with quite a few through this procedure!

[agile wedge]

ask wolfram alpha

is that covered in class ?

[cold needle]

folks

it has come to my attention

that i have no recollection of how to compute volumes of solids of revolutions

that is all

[static loom]

wow shame

disk/washer or shell method

[vagrant kestrel]

what!? they show up in all sorts of fields in math

[cold needle]

[static loom]

just think of constructing the infinitesimal width disks or shells

then integrate

[cold needle]

yeah i feel like

[static loom]

ez pz

[cold needle]

this is easier if i loosen up

and pretend im in a physics class

[static loom]

draw a picture

[cold needle]

cus i do integrals like these all the time in physics class without thinking about it but in the calc class they had a whole process and name for it

yeah pictures

i should say intro physics classes

folks

the issue has been resolved

i will just improvise when the time comes

[blazing pawn]

Not in full just clips

Maybe this makes me a Bad Homosexual

[pure sun]

i finally watched it in full last night

[errant rock]

great song

probably my favorite one from "marry me"

[pure sun]

because i knew i was a Bad Homosexual

for not having watched it

[grim token]

He is very nervous

[pure sun]

it's very good

also a lot of memes from drag race come straight from it

[neat lintel]

Example memes?

[pure sun]

do you watch ru paul's drag race?

[neat lintel]

Nope.

[pure sun]

oh, that's what i'm talknig about though

no

[blazing pawn]

Yeah I know most of the memes are from PiB

[pure sun]

moth said that about paris is burning

not about rpdr

[blazing pawn]

wait omg buncho have you seen grey gardens

[pure sun]

i've seen like half of it hahahaha

my bf was watching it one day and i came in like half way through

[blazing pawn]

little edie is so

are there words to describe her

[pure sun]

yeah i saw jinks do little edie before i saw gray gardens

[blazing pawn]

I think about the revolutionary costume for the day clip all the time

https://www.youtube.com/watch?v=un4ZiZ-ZLT8

[pure sun]

what seasons of rpdr have you seen/are you currently watching?

[blazing pawn]

Ive seen uhhh

1, 2, 4 to 7, 9

the later ones are less fun to me for some reason

[pure sun]

yeah i agree with that

i havent seen 1 or 2

i thought 3 was pretty good, just really really long

5 and all stars 2 might be my favorites

I watched AS2 right after 5

[blazing pawn]

2 is really good

[pure sun]

(AS2 has a lot of the season 5 queens on it)

[blazing pawn]

AS2 is just season 5 part 2

[pure sun]

I watched the first episode of 2 a couple days ago

[blazing pawn]

lol

[pure sun]

i'll try to watch more soon

(which is why this is on my mind)

have you seen AS2?

[blazing pawn]

ive seen some of it

also all stars 3

[pure sun]

I think it's pretty good

[blazing pawn]

which is

lol

[pure sun]

agreed

[blazing pawn]

im kind of excited for 6

maybe

[pure sun]

yeah I'm tentatively excited

[blazing pawn]

i learned that trinity k bonet is transphobic lately which was sad and also

thats like 2 out of 2 trinitys

did you hear about trinity the tuck making a reddit account to pretend to be a black trans woman to defend herself online

[pure sun]

oh no :(

yeah i knew about triinty the tuck

not trinity k bonet though

yeah trinity the tuck saga was really something

nothing compared to the robbie turner saga though

[blazing pawn]

Holy shit Robbie Turner

I feel so bad for her

She just like quit everything

[pure sun]

yeah

she clearly just had a lot of stuff going on

i dont really know much about it other than that

[blazing pawn]

i hope shes

idk in a better place

[pure sun]

yeah

[blazing pawn]

but shes probably never coming back to drag

[pure sun]

yeah

https://www.youtube.com/watch?v=NssSwYHzGOg

i think about this all the time

[blazing pawn]

the bus stop jokes are kinda yikes

roxxxy has said shes not comfortable with them

[pure sun]

oh

[blazing pawn]

but it also might be different when its a friend and not like

[pure sun]

i didnt realize that

[blazing pawn]

hateful strangers

[pure sun]

yeah i thougth she was in on it in this situation

which is why it's different than just like

reddit comments

[blazing pawn]

my favorite read was alaskas

[pure sun]

on alyssa?

[blazing pawn]

"turns out a diet consisting entirely of hate for jinkx monsoon does a body good"

[pure sun]

oh hahahaha

[blazing pawn]

I think AS3 had the best reads

[pure sun]

my favorite was the s5 one when she's like

"alyssa edwards, ms us- oop"

just because of how alyssa and coco both react

[blazing pawn]

hahahahahaha

https://youtu.be/U96SRUTvmQo?t=224 time stamped

theyre so funny

bebes and bendelacremes especially

[sly thistle]

i have seen images from this show on reddit and i dont understand i thought drag races were those cars which go vroom

[sharp mulch]

Ummmm

That's drag racing

Drag races are different

[pure sun]

haachama just announced another feet contest

an hour ago

@vagrant kestrel 🦶

[cold needle]

this probably should have gone in #chill

[astral marsh]

I think sham was talking about mtg math there

@nyann 🤔

who is this ghost reacter

@brave hollow

[cold needle]

oh ok

[native heath]

Hey!!
I am new here
I am a artificial intelligence and machine learning student in 1st year of my college
And this is my mathematics syllabus for next semester as I am little weak in calculus I want to start it early in my semester break
So I wanted to ask that can you suggest me some courses or resources from where I can learn this.

[fervent flame]

thank you

[bold ferry]

guys lets compute S9

[fervent flame]

nice meme

[neon violet]

Hello guys, I wanted to ask, is there any gallery that provides plots of basic functions like y=x, y=x^2, y=e^x, etc... made preferably in tikz (but its not neccesary)?

[leaden torrent]

pgfplots?

it uses pgf technically

which is the underlying framework of tikz

tikz is to pgf what latex is to tex (....kinda, the comparison is imperfect)

[gloomy marten]

feet pics got me like brrr

uwu

[sharp mulch]

[umbral oxide]

Hello

[deep mango]

is this what you mean when you say "2 bedroom 2 bath"?

[sharp mulch]

Did someone ping

[umbral oxide]

I did

[sharp mulch]

Ok

I hope it wasn’t anything important

[umbral oxide]

I just said hello

[sharp mulch]

Oh ok

I was too lazy to scroll up

[umbral oxide]

Good morning

[deep mango]

good morning

[umbral oxide]

Waking up this morning was an eye opening experience

[deep mango]

[umbral oxide]

[sharp mulch]

[thorn brook]

R2T2

more like R2D2

beep beep boop

[deep mango]

[thorn brook]

(translates to rekt in robot language)

[terse flax]

true

[neat lintel]

beep boop boop bop boop boop bop

[thorn brook]

I'm eating ice cream

bruh

it's not even good

🍧

[deep mango]

shaved ice

[neat lintel]

Is there a seperate solution pdf for the exercises in "topology of numbers"?

The main book doesn't have any solutions or answers for the exercises

[astral marsh]

im enjoying #serious-discussion

@glacial wasp @meager sonnet

i am the one with the blue hp bar here fiona

[meager sonnet]

I really wish I could tell you I knew what was going on in the league clips but I have no idea

Uhm

I prefer to abstain from this question

[umbral oxide]

erratic mouse movement with a lot of rage

just play osu instead

[astral marsh]

playing osu made kiting easy for me in league actually

there is a ton of crossover

at a fixed attack speed, it's literally just playing a jump map with the circles spawning in a line more or less so much easier

[meager sonnet]

I do

I'm EZDT main now

[umbral oxide]

oof

good luck to that

lol

[thorn brook]

bruh I stopped playing osu

need to start playing it again

[errant kiln]

I haven't quite found the fun in osu yet

[thorn brook]

yeah I felt the same when I started

[umbral oxide]

osu gets fun at 6+ stars

[thorn brook]

but it gets "better" later

[errant kiln]

Isn't it just an excuse for listening to music?

[vagrant kestrel]

mouse only gang

[thorn brook]

mouse is so hard tho

[modest rune]

u can just do this

[umbral oxide]

im a mouse purist but playing mouse only you put yourself to disadvatage

i can play 10.3 with a mouse

[vagrant kestrel]

sure but why does a disadvantage matter

[umbral oxide]

im an old school player

[vagrant kestrel]

unless im doing the osu world cup

[thorn brook]

playing with a mouse is a flex tbh

[umbral oxide]

nah

i bought a tablet

did not like it

for osu

i love it for math though

and taking down notes

[thorn brook]

(I tried to crank a joke btw lmao)

[umbral oxide]

saves a lot of paper man

its mostly preference anyways

reason why osu has many tablet players is because of cookiezies wanna bees

[vagrant kestrel]

the fun of osu is that there are no real songs

[errant kiln]

couldn't detect any joke

[thorn brook]

yes I know, I am bad at joking lmao

but after awhile, osu just becomes kind of boring. To get better it takes like a year of straight grinding

[umbral oxide]

anyways

[errant kiln]

Have I told you that your name reminds me of him?

[umbral oxide]

MLEM

[thorn brook]

what

wait

[errant kiln]

tinki winki

[vagrant kestrel]

purple teletubby is spoilers

[thorn brook]

OHHHH

[umbral oxide]

https://www.youtube.com/watch?v=olGnfA8_PXA

[thorn brook]

yeah I loved that series lmao

[errant kiln]

it's so creepy

[thorn brook]

why so sully

it was great

[umbral oxide]

?

what

the show was an acid trip

even for 5 year olds

[vagrant kestrel]

interesting choice of sully

[errant kiln]

should've used instead

[thorn brook]

just look at them, they are adorable

[umbral oxide]

shits creepy

[vagrant kestrel]

see that was a good joke

[errant kiln]

have you seen "don't hug me i'm scared"? 0.0

[thorn brook]

hmm no I don't think so

[thorn brook]

wait what joke??

[vagrant kestrel]

first pic is from https://www.youtube.com/watch?v=DbYC3HWpnmA

[meager sonnet]

Mouse drift is a disadvantage

[errant kiln]

I didn't know what joke he meant either, you can just pretend that he's making sense

[meager sonnet]

Especially at lower sens

Most osu mouse players use very very high sens

Compared to FPS stuff

[umbral oxide]

800 dpi standard is high sens?

never knew

[vagrant kestrel]

yea I like high sens

meaning I can play osu but no shooting game

[errant kiln]

what's the reason for that?

[umbral oxide]

thats a lie

moderate sens is king

anything up to 800-1000 is standard

[thorn brook]

(I think that plurmation was referring to this. And then I replied "what joke?" so it's epic joke time)

[vagrant kestrel]

ahhh

[meager sonnet]

800 dpi 1.p osu sens is pretty low for osu mouse

[umbral oxide]

high sens players are a myth

most people with a REAL mouse

[meager sonnet]

What

[umbral oxide]

use 800

[sharp mulch]

[vagrant kestrel]

well there's also just using a small resolution

[meager sonnet]

Every like 3 digit or lower mouse player I've seen uses very high sens

All of the top 100 mouse players do

[errant kiln]

Why would you pick high DPI though, it seems like a disadvantage, if you need to be precise.

[umbral oxide]

no

[vagrant kestrel]

time to find some mouse cams

[umbral oxide]

funorange plays at 850-900

angelsim played at 1000

[thorn brook]

it almost feels like a low sens is making you temporary good

[umbral oxide]

nah

[thorn brook]

yeah I am not claiming that it is true, it is just speculation

[umbral oxide]

although high sens can be useful fir full screen jumps

there are more high sens tablet players than mouse players

[meager sonnet]

FunOrange is mostly a stream player afaik

Tablet doesn't have high sens lol

[umbral oxide]

you can adjust it

[vagrant kestrel]

oh people actually use the 2 key keyboard nice

[umbral oxide]

and there are high sens players

[thorn brook]

yeah just make your tablet area smaller

[meager sonnet]

There's no sens

[thorn brook]

oh yeah that's true

[meager sonnet]

Yeah there's area and most people use very similar areas

Top players use larger ones often

Like WhiteCat vaxei tuna etc. All have larger areas than I use

But I mean

Whatever the sens and tablet and stuff

There's an advantage to absolute input

[umbral oxide]

tablets are only good for drawing and math (for me personally)

[errant kiln]

Can someone explain this to me?

[meager sonnet]

Tablet does take a lot of adjustment but objectively you will not have the drift that you had on mouse

[thorn brook]

I just can't have a low sense with pen. My wrist start to hurt cuz I need to move my hand across the whole god daim table

[umbral oxide]

i dont know looks like a shit post

[meager sonnet]

Mouse drift is also pretty variable depending on the mouse sensor, speed, and surface calibration if the mouse has that

Like it's not the absolute worst

[thorn brook]

hmm why the so true reaction on the post?

kinda sus

[meager sonnet]

It won't just make it unplayable or whatever

[sleek wing]

clone hero gang gang it's just gang shit you wouldn't get it bro just gang stuff gang beef gang gang

[errant kiln]

[meager sonnet]

Clone hero?

Nah

We etterna ppl here

[errant kiln]

The only music game I have ever played is Rythm Doctor

very weird game

good music though

[vagrant kestrel]

warning: rhythm doctor has some flashes

[errant kiln]

https://www.youtube.com/watch?v=BaF2YFhLaok&t=26s&ab_channel=7thBeatGames

very good music actually 0.0

[deep mango]

I still haven't tried Rhythm Doctor, I really should

I'm getting walled by B-X in ADOFAI 😭

[sharp mulch]

[deep mango]

i've gotten to like 90%

so annoying

[errant kiln]

I assume that's some osu stuff?

[deep mango]

a dance of fire and ice

i believe also made by the same people as rhythm doctor?

[sharp mulch]

Eurodancer

[deep mango]

yeah

[errant kiln]

https://www.youtube.com/watch?v=B9iDpTEcTMM&ab_channel=BWenBWen

[deep mango]

https://fizzd.itch.io/a-dance-of-fire-and-ice

yeah

[errant kiln]

music go brrrrr

[deep mango]

there are some crazy levels

i'm not that good

to be able to do the wild customs

but i've gotten good at some of the not super easy customs (and almost all the official levels, just working on the extra one right now and after that i unlock 2 more extra ones)

maelstrom is probably my favorite level, i doubt i'm ever going to be good enough at the game to beat it
https://www.youtube.com/watch?v=On0uANx8F24

[thorn brook]

Seems like fun tbh

[deep mango]

it's a pretty addicting game

[vagrant kestrel]

geometry+music

[deep mango]

the free version on the website is not super easy to play

[errant kiln]

geometry dash? 0.0

[deep mango]

it's just choppy

[thorn brook]

so it's a paid game?

[deep mango]

now that i'm not crap at rhythm games i should retry geometry dash

yeah, it's pretty cheap but the full game costs money

[vagrant kestrel]

yes but fire/ice and rhythm doctor have large demos

[thorn brook]

I'm broke

🙁

[errant kiln]

I'd like to correct my statement: I also played Geometry dash.

[deep mango]

i remember the rhythm doctor demo being really good

[errant kiln]

buy it, cool game

[deep mango]

ah, my brother has it and i have family sharing

so i can play it

just like

only when he's not using the library

[errant kiln]

pff, priviledged

[errant kiln]

So wait, even if you want to play different games, you can't?

[deep mango]

yeah

i mean i can play my own steam games and he can play his own

but if he's playing any steam game on his account

i can't play any steam game on his

and vice versa

[thorn brook]

ah, my sensei has fire/ice and I have sensei sharing

[deep mango]

family sharing used to be nicer than that

[errant kiln]

have any of you played frostpunk?

also great game

[vagrant kestrel]

it gud

simcity but fun

[sharp mulch]

Sim City is fun

[errant kiln]

the "new" simcity was utter bullshit xD

[sharp mulch]

What are you talking about

(SC4 I refer to)

[errant kiln]

sc4 was great

[sharp mulch]

Cities Skylines is overrated

[vagrant kestrel]

I'll take your word

[errant kiln]

I meant the 2013 version by EA, that destroyed your city if you didn't buy the dlcs

and also, you could only build within like 1m^2

[vagrant kestrel]

frostpunk is free on Epic btw

[errant kiln]

i really don't want yet another launcher

we have Battle.net, Uplay and Steam already

huh

I am not sure what to think of this

How's that going to work anyway, Frostpunk already had some perfomance issues on pc

[vagrant kestrel]

farmville-clone

[errant kiln]

did you play the new watch dogs?

Like cyberpunk, everybody forgot about it, once it came out.

[thorn brook]

watchdogs 2?

[errant kiln]

No.

The one that played in London

that typo though xD

[thorn brook]

lmao I didn't see it

which watch dogs wtf?

I can't find it

oh I found it

[errant kiln]

Watch dogs Legion

[thorn brook]

oh no way

I have to play it

hmmm or do?

[errant kiln]

I didn't find it that good, honestly.

[thorn brook]

it almost looks like cyberpunk

[errant kiln]

meh

that would imply it is terrible xD

[thorn brook]

yeah lmao I didn't like cyberpunk that much

[errant kiln]

but you didn't even really have a protagonist, you can switch characters just by walking by.

[thorn brook]

ohh I see

[errant kiln]

I liked Watch Dogs 2 though, contrary to the popular opinion.

[thorn brook]

yeah I loved it too

but I think that watch dogs 1 was better

it just had a better story

[errant kiln]

I liked the story, although one might consider it cringe

[neat lintel]

Hello mathematicians!

I am going to enter my last year of high school and need to do a big project - I wish to do one involving mathematics

Does anyone have any suggestions on project ideas? I am familiar with programming as well

[bronze pelican]

Do you have any ideas?

[neat lintel]

I thought about making a bot to identify whether someone is thirtsty or not

and if so, give them milk

but that's beyond my abilities

[vagrant kestrel]

[neat lintel]

so other than that, no

[limber thunder]

depending on how eager you are about programming, maybe you could look into graphing Julia/Mandelbrot sets

[neat lintel]

Julia as in Chaos theory?

[vagrant kestrel]

no but yes

[limber thunder]

sorta yes, it's a thing in dynamical systems

[neat lintel]

What does it represent?

I have a fundemental understanding of Chaos theory as I took a class about it

[limber thunder]

oh cool

so you can consider some function p(z)=z^2+c, for some complex number c, and for a given point z look at the sequence z, p(z), p(p(z)), p(p(p(z))) and so on

for some complex numbers z, that sequence will diverge to infinity

but for some it won't

iirc the set of those that don't is the Mandelbrot set

[neat lintel]

Ah

[limber thunder]

so intuitively the set of points in the complex plane that are "stable" or "not chaotic" for that dynamical system

[neat lintel]

When comparing sequences of z, does c change as well?

[limber thunder]

I'm not sure how I'd implement a program to graph these sets but there's tons of resources online, and understanding the code and some of the maths behind it might make a fun project

[limber thunder]

c is a fixed parameter

[neat lintel]

Ah

[limber thunder]

different values of c give differently shaped Mandelbrot sets

[neat lintel]

now that's interesting!

I like how one is using complex numbers here instead of real numbers in r(x-1)x (if I remember correctly)

I am going to look into it now, thank you Derivada!

[limber thunder]

ah yes, the logistic equation

[neat lintel]

So that's what it's called

Studied it in Swedish so I was unsure of the name

[limber thunder]

there's a bit of relation between both, for some values they're conjugate systems (a technical condition, but essentially they have the same behavior)

[neat lintel]

behavior as in if they diverge or converge?

[limber thunder]

but yeah studying dynamics in the real line is diff. vs studying in the complex plane

[limber thunder]

sort of, basically there's a function between both their domains that sends e.g. periodical points to periodical points, diverging points to diverging points etc.

but that's on the real line

and for some parameters only

[neat lintel]

gotcha

I've already programmed a grapher for the logistic eq so I'll try doing the Julia set now

really appreciate what you do 🙂 !

[deep mango]

in general, i recommend checking out various math youtube channels for ideas on projects. specifically 3blue1brown or mathologer (i think especially mathologer) might have cool videos which inspire you on different sorts of projects you could do! but julia sets are very cool too.

[neat lintel]

@deep mango Big fan of 3b1b - although I have not received any ideas from watching his videos; I'll check mathologer now. Thank you for your suggestion, Ryc!

[deep mango]

Yeah, with those it's more about "hey I found this video really fascinating, I'd love to go deeper into that topic"
The nice thing about 3b1b is that you could use his animation library (or whatever it is) to make a really impressive project

that should be totally available to use

for how to animate like 3b1b videos in python: https://www.3blue1brown.com/faq#manim

@neat lintel pinging just to make sure you see

whatever you decide to do, i think you can find a cool math project to work on!

[deep mango]

ah.... the gentle bubbling creek that is discussion-2...

[sharp mulch]

[cold needle]

i am going to stir it up

Watch this

[sharp mulch]

So the gacha game I played died

I've picked up a new one

[cold needle]

yeah i have nothing guys sorry

Pranked.

rip ange

[sharp mulch]

This new one also has hot men

But sort of a diff vibe

Like

In the old one

[deep mango]

how would you describe the vibe

[sharp mulch]

It was like

Hot men to date

In this one

It's like

Shounen characters who are hot

You know

Also definitely less abs

[deep mango]

i do not know the meaning of shounen

[sharp mulch]

Like

The anime genre

[cold needle]

like

i can't think of any

i forgot all of them

uh

[devout nacelle]

Anime genre for young semi-horny guys

Naruto

One Piece

[deep mango]

[devout nacelle]

This kind of stuff

[deep mango]

[devout nacelle]

Like the primary theme in Shounen is action

With young male audiences in mind

[sharp mulch]

Oh yeah this one has non-background female characters

That's a big difference

[boreal sage]

shounen is analogous to YA

[sharp mulch]

Shounen is analogous to YA targeted at straight cis males

[deep mango]

so is the shounen gacha targeted at straight cis males

or is this an explicitly gay gacha

[sharp mulch]

It is targeted at straight cis males

The previous one was targeted at straight females

[deep mango]

i see

[neat lintel]

I should try watching some anime that are targeted at gay women, they are probably good

[sharp mulch]

[neat lintel]

Gay women and straight men are probably sort of like convergent evolution or whatever the term is, like two species that developed a characteristic that are different in their composition evolutionary path but they achieve the same effect

[sharp mulch]

[summer nest]

[vagrant kestrel]

[summer nest]

Pause and ponder

[deep mango]

[neat lintel]

I know, they are not quite the same, but they are similar, you have to agree

[sharp mulch]

[sick burrow]

[deep mango]

[modest rune]

cursed content as usual

[bronze pelican]

"species"

[broken scaffold]

thats the level of cursed I come here for

[limber thunder]

[sharp mulch]

[neat lintel]

just to be clear, i never said gay women and straight men are different species, i was just saying the idea is sort of similar

i don't think i am saying anything crazy here, just pointing out a connection

Now: loud vampire

[astral marsh]

no league, sad, but i folllowed anyways

i know literally none of these games

must be normie games then

[sharp mulch]

She also does math streams sometimes

[bronze pelican]

:0

what kina math

[cold needle]

one day i hope to become so based that i can do math streams or just discuss regularly

like daminark on video or daminark on text

[last oxide]

you already do that fren

you do talks

[cold needle]

oh

i see

[mortal oasis]

@last oxide Think Fractal think if you actually knew the show it would be Think Fractal

[last oxide]

?

which?

[mortal oasis]

invisible

mostly meming

[cold needle]

invincible

[last oxide]

I watched invincible

[mortal oasis]

learned its apparently not actually

Think mark think

its just think mark

[light needle]

Mandela effect

[cold needle]

lol

[mortal oasis]

^^^

blew my mind

[last oxide]

Ill embrace the mandela effect

[mortal oasis]

and now share when i can

oh yea for sure

[cold needle]

it sounds better the way it is rn

[mortal oasis]

just wanted to share
