[wintry chasm]

Just make a channel publish there

[fair herald]

Yep, only my brother, who is an IITIAN, knows about this and he forced me to work on it otherwise else i wouldn't get motivation to keep working on it.

[fair herald]

I will try someday in future

'Well I gotta study'

[lone garden]

I like math and some people dont know

like my math teacher

[fair herald]

It's better you tell your teacher 😭

Teachers compliments helps a lot and the fact that it keeps us motivated to do better in the subject and impress the Teacher

[lone garden]

he actually treats me like a king bc im the only one whos intrested in math and good at it

when i raise my hand he knows im gonna ask something important

and i dont even try to participate bc he knows i understand the material

[dull badger]

Do ppl know how to help teach a kid pre-algebra concepts

cause my brother whos in primary school has been falling behind his classes, and he can't grasp concepts like arithmetic with fractions or translating word problems to equations or even isolating variables and solving equations and I don't know how to teach that to him

Personally, the way I learned these things was out of necessity, I wanted to pass the algebra 1 placement test at my school so I just studied and did problems but for him there is absolutely zero motivation to learn any of this stuff

[green osprey]

Try using mnemonic devices?

What's he fully struggling with rn? Like the most

[dull badger]

I think the biggest thing for him is he completely shuts down whenever there's something that he can't fully understand, so I guess the biggest thing for him is just algebraic manipulation

Like he was doing a problem x / (6/7) = 3 2/5 (idk how to notate mixed fractions)

[green osprey]

does he struggle with fractions

ah

well does he understand to isolate the variables?

[dull badger]

I honestly can't tell, because I asked him "what does division by a fraction look like" and he said "multiply by reciprocal" so he gets the concepts in theory?

[dull badger]

I don't think so

[green osprey]

That sounds good...

[green osprey]

To help just tell him that the xs and ys are racist towards numbers and they dont wanna be next to the numbers

😂

[green osprey]

This is somewhat a joke lol, but it might work 😭

[dull badger]

maybe something like that will work, issue is a lot of the time hes doing his hw he's super grumpy and not very receptive

[green osprey]

Ah.

Is it only math?

[dull badger]

math is probably the place where it shows up the most bc that's where hes being most challenged

[green osprey]

Cuz I'mma be honest, math isn't my PASSION... but Im working on that cuz when I looked at the word as mathematics instead of it's shortened counterpart... it made it seem awesome

Math is a language

[green osprey]

gotcha

[dull badger]

that's what im trying to convince him of

[fair herald]

You cannot force a child to do maths unless he is willing to
Like if one is not willing to do maths, he'd never get better at it— not even basics

[dull badger]

ig at this age he just isn't super into learning (?)

[fair herald]

What's his grade?

[green osprey]

I mean im only 15

[dull badger]

5th, by the american system

[fair herald]

Oh American system

[dull badger]

but hes taking math classes outside of school

and this is what hes struggling with

Hes 10

[green osprey]

Oh dude he's way ahead then (by the AS) cuz most kids here are in Algebra 1 by freshman

[fair herald]

He may get interested in future
If he does then well he'll get better it if not then...

[green osprey]

He's not behind at all he's actually ahead

[fair herald]

10?

I really got better at maths in 7th grade(indian system)

[dull badger]

ig so, but he's also sorta on the gifted track as well? maybe we just have to wait and see

[fair herald]

Like from this stage my maths did become better than average

But i was interested in maths since 3rd grade

[fair herald]

Yea wait

[dull badger]

I started to be somewhat interested in math when I was in 8th grade and started watching veritasium and 3b1b

so i skipped like 3 years of math from 8th to hs

[green osprey]

love Veritasium

[dull badger]

maybe i have to introduce him to the imaginary numbers video and get him invested 💀

[dusty moth]

Hello discussy 2

Oooh different people

Thought it'd be the usual

[dull badger]

hi

[dusty moth]

Hello

I was supposed to be doing fluid mech but pomodoro went off

So here we are

[dull badger]

damn

im lowk supposed to be doing bioinfo research but my mom made me help my brother and i came here for advice

[fair herald]

Oh fluid mechanics

I am generally good at mechanics except fluid 😭

I can do normal numericals of fluid mechanics

[dusty moth]

Ooou

Do you like datum lines?

[sharp mulch]

[shadow palm]

Why does @sharp mulch have me blocked??

[gloomy marten]

maybe it's their wish

[chilly totem]

I guess its good

[rare verge]

Hi

[fair herald]

Hello

[rare verge]

Wait do you read literature

[fair herald]

Very much

[rare verge]

No wonder I saw that pic in profile

[fair herald]

I know how to read and write

[rare verge]

Your favourite author ?

[fair herald]

Ye
I read more than that ig
Including webnovels

[rare verge]

Same

[fair herald]

There are many

In case of webnovels: cuttlefish, and g3

[rare verge]

Did you read beginning after the end

[fair herald]

And classic: Fyoder

[fair herald]

Yes

[rare verge]

What do you think of it?

[fair herald]

Great but peak

Since it was TM first work

But character execution wasn't well

Like agronq

Agrona

Hype

[rare verge]

Do you also read philosophy?

[fair herald]

I write philosophy

[rare verge]

Dang

I wanna start reading books can you recommend me some books for reading

[fair herald]

Classic?

Brothers Karamazov
Crimes and Punishment
The Idiot
The Demon

[rare verge]

Hmm I will save that

[fair herald]

Whay genre do you want to read ?

[rare verge]

non fiction

I want non fiction

[fair herald]

Not my thing 😭

I rarely read non fiction

[rare verge]

Dam ok

[fair herald]

But frierich

Fredrich

Idk spelling

Read his books

[rare verge]

Ol

[fair herald]

In order

[rare verge]

Ok

Fredrich engels?

[fair herald]

friedrich nietzsche

[rare verge]

K

[austere slate]

I think The beginning of Infinity by Deutsch will be a good read then.

[minor needle]

hey guys

[minor needle]

1984

The trail

Mein Kampf

[unborn sandal]

For Russian translated philosophy books, just be aware that the translations aren't particularly good

Most of them aren't done with people by people without an understanding of English as good as it needs to be

and even if it is done well, it isn't good compared to the Russian

[rare tendon]

Is there a Lean discord server?

Or a lean/PA channel here?

[surreal sapphire]

no

[surreal sapphire]

whats wrong with the official lean zulip

[rare tendon]

I haven't used it before so I was hopin for a dc server. I guess I'll have to do it on zulip. It's probably a rather stupid question though.

[surreal sapphire]

its just that the entire lean community is there, since its the official community hangout

they are fine with stupid questions

[rare tendon]

Ah ok, thanks. I thought it is only for advanced discussion given the big names on there

[surreal sapphire]

you can find some place to ask on this server as well but not sure too many people here know about lean

[restive pier]

hello everyone

[green osprey]

Hello!

[minor needle]

hi

[fair herald]

Hello

[restive pier]

hows ur day

[fair herald]

Very bad

[restive pier]

why

[fair herald]

Idk how a person's misunderstandings can be removed

I am deep penitence from last two months

It has ruined my mental health

But didn't let it ruin my academics

It all feels dull

[restive pier]

i am so sorry bro, anythign to make u feel better

talk anout maths?

about*

[fair herald]

Sure

[restive pier]

so, will you persue a career in maths>

like in math acedemia

[fair herald]

Yep

I am aiming for Harvars

D

So it's obvious

[restive pier]

Nice bro

what will you specialize in

[fair herald]

Maths and Physics

[restive pier]

i want to go to either, the steklov institute in russia, cambridge in britain, or institute of advance study in princeton

[restive pier]

no like what topics

[fair herald]

Same i want to go for other institutes as well but, first priority is Harvard then MIT

[restive pier]

completely forgot anut MIT, same lol

[fair herald]

Calculus
And Mechanics (I and II)

[restive pier]

ooooo

[restive pier]

bro i want to become one of the worlds greatest mathematicians ever, and i hope you will too

[fair herald]

Let's hope for the best
Good luck

[restive pier]

whos ur fav mathematician

[fair herald]

newton

Wbu?

[unborn sandal]

Cauchy

[brave flare]

Why is your pfp the old server logo

I thought you were @quasi jetty for a seconr

[fair herald]

Great

[rain quail]

El khawarizmi

[rain quail]

I know a teacher in MIT
His name is Kamal youcef toumi
He is an Algerian like me
Actually he is from my city "Ksar El Boukhari"
He came to our school when I was 7 years old
He is my friend's grandfather

[fair herald]

He's my fav as well

[fair herald]

Oh!!
Bruh you are lucky.
Are you in contact with him?

[rain quail]

Not with him directly
But I am in contact with his grandson

[fair herald]

Oh Good for ya

Wyd btw?

[rain quail]

Thank you

[rain quail]

I am a highschool student
And it's my last year in highschool like what I told you yesterday

[rain quail]

And if you mean what I am doing right now
I am actually eating lol

[fair herald]

I dont have amnesia bruh

[fair herald]

Haha

I was doing a question today
And I tried to go for a different approach, and yet it was correct

for a moment I was like I found a new method!!

But it already existed

Lol

In Algebra

[rain quail]

Nice

[rain quail]

It's ok
This means that if it doesn't exist you would be its discoverer

[fair herald]

Nah bruh
Many would have done that
already

It happens with a lot of students ig

[rain quail]

It happened to me several times
In the lesson of probabilities last year for example
And this year we are studying the things that I discovered last year lol
I really thought that I was the first one to discover them

[fair herald]

And it's great way of a compliment like your grasp over the topic is increasing

[untold iron]

toshifumi hinata is too good

[fair herald]

Aye aye

A Cat is wandering

Someone capture this 'wandering cat'

[untold iron]

so

[untold iron]

WAIT

THATS ME?

NO

[fair herald]

Ye, dats you

,cat

?purge

Oh shit, i forgot I aint a mod of this serv...

[thick knoll]

Hmmmm

[untold iron]

moderator reflex

ahh moment

[fair herald]

😭
I used to abuse mod powers a lot

[untold iron]

u was mod?

[fair herald]

No not here

In other servers
Especially writing servers

[untold iron]

ok

so informational dude

[fair herald]

[raw maple]

So im almost done with basic arithmetic

Like completely

So whats up with complex arithmetic

Is that number theory???

Asking here cuz its not relly like a question that i can ask in the help servers

I mean i can its just

I feel like it would be a waste of the helpers time and space that someone else could be using asking better questions lmao

[vocal schooner]

as in 1+3=4?

[vivid halo]

not really!

[raw maple]

is complex arithmetic a thing??

or does it just end after all that

i know that arithmetic is needed for other areas of math like for example algebra is just arithmetic but instead now there is variables and equations and or inequalities

but arithmetic evrytime i go to research more about it i keep hearing people say basic arithmetic

[magic python]

So arithmetic on complex numbers?

[raw maple]

i was wondering if it eventually does get more compex or does it just stop there after that

[magic python]

That's just part of elementary algebra

[raw maple]

thats what complex arithmetic is

just algebra

bra

alge

brahhh

algebrruuuuuhhhhhh

okay is there higher level arithmetic?

[magic python]

Again explain what you mean

[raw maple]

complex arithmetic works with complex numbers but it is not the same as just algebra

[magic python]

Doing arithmetic on complex numbers is in elementary algebra.

Afaik

[raw maple]

i know that arithmetic is needed for other areas of math like for example algebra is just arithmetic but instead now there is variables and equations and or inequalities

but arithmetic evrytime i go to research more about it i keep hearing people say basic arithmetic

i was wondering if it eventually does get more compex or does it just stop there after that

[magic python]

Broken record...

[raw maple]

is a complex number just a variable???

[magic python]

NO?

It has a value

[raw maple]

you asked me to ask the question again

wdym

[magic python]

No I asked what you mean by complex arithmetic.

You don't explain what you mean

[raw maple]

idk what it is thats what im trying to figure out

[magic python]

You can do arithmetic on number in C (complex numbers)

[raw maple]

i did

[magic python]

No not properly

[raw maple]

what are you saying

[magic python]

You could still mean many things by complex

[raw maple]

okay im asking what complkex arithmateic is

idk what it is

[magic python]

"Does it get more complex" no afaik arithmetic is exclusively the 4 arithmetic operations

[raw maple]

afaik

[magic python]

Elementary algebra introduces more operations

[raw maple]

what is afaik

[magic python]

As Far As I Know

You seem to be using arithmetic wrong from my understanding

I could be wrong

[raw maple]

no thats not true elementary arithmetic includes exponents roots and logs

[magic python]

That's elementary algebra

[raw maple]

yes you are wrong

[magic python]

Those are not arithmetic operations

[raw maple]

yeah thats more than 4

yes they are

those are operations

is arithmetic not values (numbers) and operations (hyperoperations)

[magic python]

Okay, in a wider sense those are

I was taught the distinctions differently

But still, what do you mean by more complex

[raw maple]

ive heard people talk about complex arithmetic and higher level arithmetic so its gotta be a thing right???? right????

idk

thats what im asking

ive heard people talk about it

but i dont know what it means

[magic python]

Higher level arithmetic isn't a term I have heard before, I'd recommend #❓how-to-get-help for further help

[raw maple]

if theres 2 meanings that fine what are thay?

[magic python]

They know more about the definitions of exact things

[raw maple]

alright i just didnt want to take up people time cuz i thought this question was easy

easy enough to have someone solve it here but ig not

[magic python]

Fair

The help channels are better anyways afaik

[raw maple]

ill try disscusion 1 first

i know

[magic python]

People tend not to care about questions especially in #discussion #serious-discussion or #chill

[raw maple]

true

100

i know that arithmetic is needed for other areas of math like for example algebra is just arithmetic but instead now there is variables and equations and or inequalities

damn hold on

sorry

[magic python]

It's fine

[fresh comet]

[shadow palm]

Hey higher

[raw maple]

dude this math server is the goat

i just wanna say thanks again guys

i know im prolly annoying sometimes but you guys are doing a good job and helping people out aton ive learned a bunch sense joining i know im annoying sometimes but i appreciate all the help ive gotten thank you guys

[granite robin]

[snow matrix]

hi guys

good morning

[jade harness]

Here is the most important thing to remember.

[fresh comet]

what is the most important thing to remember?

[weary goblet]

who ask question to answer who is with and is?

[viral oracle]

the

[fresh comet]

[viral oracle]

[young ether]

does nobody else think it's really fucking weird that thermodynamics and information theory are connected

like i forget exactly what the proof was but someone responded to the maxwell's demon thought experiment about reducing entropy by physically separating hot and cold molecules

and that would theoretically violate the second law

but the information required to intentionally sort the gas molecules necessarily creates heat

information creates heat

like WHY

also like uhh why did the second italics not work

[magic flicker]

The space

Asterisks need to touch the word, it prevents accidental formatting, also a asterisk followed by a space typically adds a bullet point but since there's text in front of it it doesn't format it that way

[zinc talon]

heat is just just energy

[young ether]

yeah the same energy that relates mass and the speed of light

it's just extremely interesting that information is also fundamentally related to that same energy

[young ether]

oh i didn't see that oops

yeah i know that's what describes and predicts the relation

but that doesn't do much to contextualize it

[lunar dock]

define information

on a subatomic level

[young ether]

well landauers principle defines information as k sub b

which is just a number of bits

so this is already assuming it's binary information specifically

wait nvm that's the boltzman constant

[lunar dock]

define bits

[young ether]

... a one or a zero?

[lunar dock]

at a subatomic level

what is a one

what is a zero

[young ether]

in this case an electron trap with or without a charge in it

[young ether]

we don't have subatomic computers yet

it'd be a single unit of storage

[lunar dock]

we cant define information on a subatomic level then?

then is info really fundamental

[young ether]

so just one ion trap on a piece of computer memory

[young ether]

this feels very much like semantics

do you have a point you're getting at?

"fundamental" is highly subjective

like is it really fundamental if it's subatomic but still doesn't describe quarks

or does it have to describe all the smallest physical structures we can see

physicalists 🙄

[lunar dock]

idk bruv

i am sick

and writing anything

i think

💀

[young ether]

i can't upload an image brah

well look up landauers principle

the E you're relating is the minimum energy for one bit of information

and that's to erase it

so to delete information you need to release energy in the form of heat

and the equation defines the minimum amount of energy required per bit

[lunar dock]

hmm imma look into it

[young ether]

#chill message

there

how do i get image perms btw

[lunar dock]

nice

[agile fiber]

you get image permissions when you get an activity role (once the bot decides you are sufficiently active in the server)

[young ether]

ohh

yeah i very rarely think of any maths worth talking about 💔

it's usually just me stumbling over shit that is way out of my element

[agile fiber]

since it's an equation though you can just type in LaTeX and @fathom swallow will render it for you as an image

[young ether]

oh good idea

how do you uhh do that

😭

[lunar dock]

yo does anyone here like physics

[young ether]

i like physics

[lunar dock]

noice

anyone prepping for olymps

[young ether]

when it's not spending 10 billion on another particle accelerator

[lunar dock]

?

[viral oracle]

$E \geq k_B T \ln(2)$

[agile fiber]

you can learn the basics of LaTeX in the pins of #latex-help (start with the cheatsheet, oldest pin)

[fathom swallow]

Hanako(x, y); ∂(fox)/∂x

[young ether]

woah

[young ether]

is it like a programming language?

[lunar dock]

10 bil is too low

[young ether]

yeahhh

[lunar dock]

spend like 100 bil on a new particles

accelerator

[young ether]

if they were spending that much on fusion I'd be all for it

[agile fiber]

it's like a programming language for producing pdfs yes

but a lot of people use it specifically for its equation rendering capabilities

[lunar dock]

jus use gpt dawg

🥀

[young ether]

but particle accelerators do nothing for us but give us whispers of fundamental physics

[young ether]

brother

if i wanted a bunch of confidently wrong math slop I'd be just typing in main channels here 💔💔

that's a joke i don't think anybody does that here

but ugh i see it everywhere on twitter

if i was gonna use any math ai it'd be wolfram alpha

LLMs are way too nondeterministic for math or any other highly specific and precise medium

[lunar dock]

it would be more efficient to just ask gpt how to type in latex rather than learning the entire lang just to type like 1 equation per week💀

[lunar dock]

i was just talking about typing using latex

not learning math

[young ether]

yeah but like you could also use the resources that people have already worked for and tailored instead

using mainstream ai is lowkey dumb as fuck

unless you're self hosting it

[viral oracle]

if one plans to study physics or math in the future typesetting would be quite often enough that you'd type LaTeX a lot

[young ether]

you're supporting a business model that is screwing over everything from the economy and environment to our mental health

[viral oracle]

so it is worth your time learning LaTeX, yes

[lunar dock]

yeh in those cases learning latex is good

i agree

[young ether]

learning anything is almost always worth your time tbh

#ilovelearning

LOL

[jagged forge]

learning what words to write in a yaml key is worth no one’s time fr

[lunar dock]

i mean

learning how to type using your toes

just saying

[young ether]

what's yaml key

[rocky shuttle]

im not gonna waste my time learning the first 1000 digits of pi in decimal representation

[young ether]

okay fair

learning almost anything you have any incentive to learn is almost always worth your time

that's my revision

[viral oracle]

zan showing up in a channel I rarely show up in count +1

and therefore a is in order

[young ether]

okay but what if you're stuck on the forest without a phone and you need to manufacture a circle to 0.00000001mm

what are you gonna do then huh

[viral oracle]

and you somehow have a measuring device that has that kind of precision...?

[young ether]

you can lock in super hard dw

[rocky shuttle]

do you really rarely show up here...? i skim a lot of channels

[lunar dock]

i learnt how to count in ternary using my hands and my toes

do i regret it?

maybe

[viral oracle]

I don't often show up in social channels hahah

my main areas are bots, hlounge, and from time to time my AA/analysis threads

[young ether]

it's good for your brain at least

[jagged forge]

dumb software engineering thing that every software engineer has to do occasionally

[young ether]

💔💔

just vibe code it bro

[lunar dock]

[rocky shuttle]

learning the first 1000 digits of pi in decimal representation still wouldn't help me

[young ether]

that's a joke

to be clear

because some people do be giving that as real advice

[lunar dock]

guys will i get a job or will ai make me a slave when i grow up?

[young ether]

tell that to your hippocampus

[lunar dock]

what do yall think

[young ether]

atp to get a job you need to work well outside the typical social structure

[lunar dock]

scamming?

[young ether]

at least to get a job that will make you adequate money to live

[young ether]

i mean it would make money

but i meant like

specialist services

or like

manual labor

[noble fossil]

i just joined the conversation, it depends on what kind of job you're talking about

[rocky shuttle]

be born outside the typical social structure?

[young ether]

learning a specialized skill in construction is always a good option

as long as you're in an area it's useful

[lunar dock]

hm tho im weak asf

[young ether]

brickmasons are always gonna exist

[lunar dock]

i aint doing no manual labour

[young ether]

learn to make electronics then

or fix them

or try your hand at art

[noble fossil]

any type of engineering tbh

[young ether]

just do NOT get a 9-5 at mcdonalds

[lunar dock]

hmm

[young ether]

unless you absolutely have to

[lunar dock]

💀💀🥀🥀

[young ether]

same goes for any corporate wage slave job

[lunar dock]

i mean i am set financially tbh

i have a home

and parents

🥀

[young ether]

being paid by the hour is never a fair trade because time is the only true scarce resource

[lunar dock]

just live at their house

until i get evicted

[young ether]

meanwhile your money become worth less every day

[lunar dock]

there always that one guy on discord who speaks facts

[young ether]

yeah that's a safe bet

[noble fossil]

how can u benefit from that time if you don't have money

[young ether]

just make sure you got shit ready before you get evicted

it's a lot easier to make a stable living when you're already housed

[lunar dock]

hm

is prepping for phy olymp

[young ether]

by using the time to make more money than you would otherwise

[lunar dock]

worth it?

[young ether]

it's really easy to make more than $15 an hour if you're smart enough to figure out a way

and idk abt you but it's a lot easier to be smart than to work an 8 hour shift

[noble fossil]

yup that's my point

[young ether]

i mean define worth it

it'd be rewarding

[noble fossil]

there should be balance

[young ether]

but maybe just not financially

[young ether]

absolutely

[lunar dock]

i mean is it really worth it to spend this year

[young ether]

as with anything

[lunar dock]

practising for it

and trying to make it to the team

[young ether]

well how much of a commitment would it be

like are we talking multiple hours every day

[lunar dock]

imma have to spend like atleast 3 hrs per day

every day

[noble fossil]

idk what you're studying guys but for my case time is your ennemy

every second counts

and i mean that literally

[lunar dock]

also i am good at physics

at least i think so

[noble fossil]

what field exactly mecanics electronics thermodynamics...

[lunar dock]

mechanics thermo

and fluids

[noble fossil]

the whole day

[lunar dock]

im currently learning electro mag

[noble fossil]

cool we just started thermo it's kinda hard tbh

[lunar dock]

it is

really

the hard questions are pretty hard

tho the easy ones are just formulas

[young ether]

time is my enemy when i could die at any second without warning

that goes for all of us

time is the most precious thing you have

[noble fossil]

for sure

[young ether]

and the best part is you're entitled to it

[noble fossil]

best part?

idk 'bout that

[young ether]

i still find it insane that people willingly give a third of their waking lives to MCDONALDS of all places

or WALMART??

[lunar dock]

how old are ya all

[young ether]

19

[young ether]

what would you say the best part is?

[lunar dock]

im 16 🥀

[young ether]

L bozo

[noble fossil]

idk yet looking for it

[noble fossil]

18

[lunar dock]

noice

[noble fossil]

16 and studying thermo that's cool

[lunar dock]

just wanted to make sure i am not getting advice from like 13 year olds

💀

[noble fossil]

relatable

[young ether]

real as fuck

[lunar dock]

i mean its in the olymp syllabus

[young ether]

i almost failed geometry and never even took calc

so you might as well be

[lunar dock]

i mean

who cares

why you in the math server tho

[young ether]

i like math in a marvel in the beauty of it kinda way not a shut up and calculate kinda way

[lunar dock]

oh

nice

[young ether]

but I've been learning how to use it and that makes the former easier and more rewarding

[noble fossil]

nice

[noble fossil]

yeah abstraction in maths is pure beauty

[young ether]

ngl i got so excited the first time i was able to look at a fairly advanced equation and actually get it

[lunar dock]

sem

random 3b1b vid

[young ether]

like not in a "i could plug anything into these variables and calculate it exactly" type of way

but more of a "i understand the abstract mechanism at play here"

[lunar dock]

fr dude

[young ether]

but a lot of ppl only really value the first one which is lame

[lunar dock]

ts is like enlightenment

[young ether]

LOL idk abt that

but it can definitely feel like it sometimes

[lunar dock]

hm

anyways

[noble fossil]

yup

idk if you know about fiels sets rings ....

that's something

[round abyss]

#groups-rings-fields <--

[lunar dock]

bruh i was trying to send a good question

but then realised

i dont have img perms

bruh hh

[young ether]

i have never heard of it

[noble fossil]

fr?

[lunar dock]

same

[young ether]

no way you have a website

that's so epic

i wanna make a website but html is so hard 💔💔

[round abyss]

w3schools and !!! emmet abbr are your friends

[young ether]

omg yes I've been using w3schools

im learning css rn

cuz i know the basics of html from a class i took like 4 years ago

but i wanna make a pretty website

yours is a vibe it's really cool

[round abyss]

appreciate it :3

if you want inspiration, neocities and nekoweb have a lot of nice places to nab css ideas from. we ❤️ f12

[young ether]

im hosting mine on neocities but rn it's basically a hello world script

also what's f12?

like the key?

[round abyss]

inspect/debug mode

free html 🤑 yar har 🤑

[young ether]

OMG TRUE

i remember doing that in school on the chromebooks and telling my friends i hacked the mainframe

i think it's just ctrl + u

on chromebooks at least

[round abyss]

damn, it's always been ctrl+shift+i for me on all browsers tbf

[young ether]

hmm idk i haven't done it in a while

I'll try it later tho im just on my phone rn

and for some stupid reason phones can't do computer stuff

💔💔💔

[round abyss]

i aspire to someday build a poweruser phone os for myself

[young ether]

REAL AS FUCK

lemme get a copy when you do :3

[round abyss]

open-source babyyy

[young ether]

hell yeah

all software should be open source ngl

except maybe encryption protocols

ehh idk even then if your encryption can be cracked just by seeing how it works is it really that encrypted

[round abyss]

open source SHA-1 algs 🗣️

actually idk if those are or not

[round abyss]

i mean the point is that it's difficult to reverse the process even if you have the details

[young ether]

yeah so it should be fine if people can see the source code then right?

[round abyss]

😌

[lunar dock]

almost impossible

like try reverse engineering SHA256

💀

[round abyss]

give me a quadrillion computers and a quadrillion universes, i'll have it done in a quadrillion years

[young ether]

LMAO REAL

[lunar dock]

the best i can do is 1 universe with 1 old ass laptop

and 1 month

with a firm handshake

[young ether]

only if it's not np complexity

atp you'd just be fucked

i think that's the right classification

cuz there's polynomial and non polynomial

and i think np was non haulting on a turing machine

[round abyss]

solvable in polynomial time on a nondeterministic turing machine

[young ether]

wait there's nondeterministic turing machines?

i am rusty on computational complexity i tried reading some about it for a while and forgot most of it

still have the $100 of books i bought on it tho 💔💔

[round abyss]

i.e. in some states there are multiple possible next actions

but i don't know much comp complexity theory either that's as far as i go

[young ether]

but it's still deterministic in how it selects the next state right?

or is it like hypothetically choosing every option and branching off at each point with multiple possible next states

[young ether]

we gotta call in an expert

[round abyss]

yeah, it's not a single path

[young ether]

does anyone here know computational complexity

interesting....

[round abyss]

chat is this suitable to forward to #theoretical-cs yet

[young ether]

are there physical nondeterministic turing machines or do they only exist in theory

[round abyss]

i'm pretty sure they're more of a thought experiment, but if you consider RNG nondeterministic i guess that would count

[young ether]

I forwarded that to that channel

[round abyss]

not that a turing machine itself could really exist physically anyway lol

[young ether]

turing machines are real tho....

your phone is a turing machine

im pretty sure it's turing complete

technically

[surreal sapphire]

you dont have an infinite tape

[surreal sapphire]

this also depends on whether you believe we have access to randomness

every physical computer is nondeterministic because random events can flip bits

[young ether]

i have a tape loop tho

but it doesn't record audio very well i think i put the tape in the cassette inside out

[surreal sapphire]

turing machines have infinite tapes

[round abyss]

adjoin \infty to the infinite tape and make it a loop, easy

[young ether]

oh yeah idealized turing machines do

but like the computer that cracked the enigma code was called a turing machine because at the time "computer" was a job title

[surreal sapphire]

turing machines are already idealized, there is no such thing as a non-idealized turing machine

well, there are turing machines that are supposed to model real computers more closely, but those have an infinite tape too

[young ether]

there's no such thing as a computer which evolves into multiple simultaneous states?

[surreal sapphire]

you will mostly use probabilistic polynomially bounded turing machines to model "realistic computers"

[young ether]

do you need a literal infinite tape if you can already load the read and write heads with an unending stream of binary information

[surreal sapphire]

you need an infinite tape to model computation mathematically

[young ether]

there is effectively zero practical limitations on string length in modern digital computers

[young ether]

wouldn't that just be np then?

im talking for p class problems

[surreal sapphire]

no

[young ether]

are there p class problems that require infinite string length?

[surreal sapphire]

i think you are confusing lots of things

turing machines that halt will always use just finite amount of tape

but your computer has a finite amount of tape a priori, so there are things that can "run" on turing machines but not your computer

[young ether]

okay yeah that makes sense

but modern computers are almost always turing complete right

[surreal sapphire]

if you ignore the tape issue, yes

[young ether]

as in they can run any algorithm, just not necessarily complete it

[surreal sapphire]

and some other physical issues

[surreal sapphire]

if you assume that you can just keep adding more RAM to your computers or something

[young ether]

oh yeah ram would be a problem

especially in this economy

im gonna do some refreshing on the basic terminology cuz i think i definitely am confusing a lot of terms and definitions

and then im gonna sleep on it cuz it's almost 3 in the morning

will maybe check back tomorrow we'll see

[cedar trench]

hello

[fickle junco]

Guys
m in chemistry is mass

Right ?

[green osprey]

m is molality

M is molarity

[stone meadow]

depends

both yes and no

if you are comparing speeds of 2 atoms

you can use m as mass

[fickle junco]

What the fu-

[stone meadow]

well it's like

I don't remember their mass but

let's say Hydrogen is 1 kg

while ummm

Neon is 4kg (definitely not 4kg)

[split stratus]

@minor condor answer

[stone meadow]

if hydrogen moves with 1V
neon moves with 1/2V

it's related to the square root of their mass

but as zeta says you mostly use m for molality

most countries use MA for mol mass actually but well it doesn't matter if the calculation is right and gets you some points I guess 😭

[fresh comet]

[lunar dock]

as in RMS speed of the gas molecule? or what

we just use molar mass

[lunar dock]

depends on the context/question

[stone meadow]

I am sorry I am not a native

what is RMS

[lunar dock]

root mean square speed of the molecule

[stone meadow]

oh... I guess so

[lunar dock]

coz otherwise idts we just use "speed"

its average speed, most probable speed and RMS

[stone meadow]

I mean the speed is related to other stuff too soo it's just

for "ideal gases"

have no idea what you call that in english

[lunar dock]

yeh, the molar mass and the gas constant R

[lunar dock]

just search it up in your native lang, and see the eng equivalent ig

[fallen relic]

yo so apparently there is a waitlist to join the physics server??

i need some advice on a physical simulation i am making tho.

can i ask here?

[gritty heath]

Yeah but there will be a much lower likelihood of someone capable and willing to help

[fallen relic]

bruh

worth a shot

im making a vehicle dynamics sim and i have two options rn for interpolating downforce/lift coefficients for components of the chassis

use a 2d AoA and slip angle map (from -10->10 degrees each axis, total velocity from the cars local forward&lateral), or assume downforce works only at 0 degree slip (maybe 1d interpolation from AoA/pitch slip for squat/dive accuracy?) and just dot product the cars' global velocity with the unit vector of the cars heading globally

the 2d bilinear interp has better accuracy but i will have to input a heck of a lot of data and manage it, but the second one is less accurate (real lift from aerofoils is designed for tolerances +- 3-5 degrees, ) but easier to implement

e.g, if i were to run +- 5 degree range with 1 degree intervals of data, i would have exactly 300 entries i need to input and tune.

[vast dragon]

Sup yall

[austere slate]

Define Technocracy

[gilded dew]

Yes that's true. Honestly I think an engineer could lead a country better.

That's given. And honestly a lot of physicists and mathematician are down to earth people and not greedy.

[austere slate]

does anybody here use Midori Broswer?

[silk yarrow]

hello gusy

[chilly totem]

Hello nirv🙌

[prisma summit]

Bilinear interpolation shouldn't be too difficult since any image or graphics libraries should have these kinds of functions built in. I reckon you might as well challenge yourself and go for the more accurate option, but in the end it depends on what you want from your simulation.

[fallen mango]

huh?

um so guys, do you guys have any site where I can play some bridg it? I found a strategy (honestly a bit of a cheat I feel personally) that seems to always work against the bot on https://www.lutanho.net/play/bridgit.html

so I need a different site (I basically put lines in the middle, and it will naively only put one line in the middle and continue trying to extending that line to the finish without trying to block me any further, which makes it lose)

[fallen relic]

Im writing the code by hand in C. Not using any matrix libs, so i am unrolling all operations into scalars and manual simd instructions if possibld

I think i'll use interpolation for now

[zealous garden]

What the fuck, why

[fallen relic]

To teach myself some new skills and for performance

Also idk how to install libs on windows lol

Same reason i had to write a small gmplib, couldnt install it

[true zinc]

Just place the code in the folder and link it in, use WSL or cygwin for a copy of gcc

Do pharmaceutical companies hire mathematicians?

[magic python]

First of all they should focus on hiring idk pharmacists probably

Or people qualified or soemthing

[sacred abyss]

I mean to say, are there mathematicians working in pharmaceutical research? My school has a research group in computational biology, modeling cells.

Sort of close

[zealous garden]

unironically, arch-based distros install development headers with every library by default

[storm sage]

They'd probably rather hire biostatisticians, computational chemists, etc., just my guess though

[storm sage]

There's definitely a lot of mathematics involved in stuff like automated drug discovery

[prisma summit]

That should be fine, bilinear interpolation is in the end just three linear interpolations anyway. It's not the most complicated procedure to implement.

[cold turtle]

Opinions on taking a discreet mathematics class before calculus 2?

[sage trench]

Nah maybe

[storm sage]

sure

[sonic sentinel]

why do teachers and professors defend their test designs saying X isn't how it works in the real world

why not give wealthy students extra marks? it might genuinely correspond the test scores better to real life outcomes

[sonic sentinel]

yea its ridiculous

[tawdry pecan]

for transparency ig

[polar widget]

Virtual reality always will see me

Virtual reality always see me

[slender kindle]

I think the test scores are a sign of competency

And nowadays everybody has an "equal" opportunity to get into certain fields of work

[sonic sentinel]

this is going somewhere

[slender kindle]

And higher grades for the incompetent rich can result in higher percentages of ppl who work but are not capable fully

So it would be a bad decision

[slender kindle]

Like, they're both incapable and powerful. So it'd be hard to fire them also

Anyone have any insight on pros to going Pure Math major instead of something like Eng. I love math and would much prefer it but I’m worried about job market and whether or not I have what it takes. Any insight?

[hybrid stump]

Same worries, except that I'm already in eng. and thinking of going to graduate school for math

[hard oasis]

If you're willing to go into industry, then the job market is quite vast. Especially if you're not afraid to do some CS as well, but that depends and is definitely not mandatory. If you wish to stay in Academia however, the job market is quite competitive and there aren't enough positions

But maths and English are two very distinct fields, so the real question is: what do you prefer most between both?

[loud seal]

1. you do what you love
2. Rule 1 is the only thing that matters in the long run

[hard oasis]

It should be easier to answer that first rather than look at the perspectives

[loud seal]

he was talking about engg.

imo

[hard oasis]

Oh engineering

Yeah he should've written it in full

[hard oasis]

Okay I see the nuance; then yeah what I said here still applies though

One thing though: if you go the full pure maths road, and push it far, be prepared to be teaching, cuz that's kind of unavoidable

[distant quail]

Ofc I’ve done most of methods
