yeah looks easy and good, been meaning to make it for a while now
Hmm maybe I should make coffee jelly
Does anyone math tutor on fiverr/ know how to set that up? i’m under 18 so idk how to do it legally
has anyone ever read A Gentle Introduction to Tensors, by Boaz Porat?
math tutor on fiver sounds mad sus
why not go to a reputable site or something
Oh that's tensors... Well go read Electrodynamics
ngl I'm not reading it for physics
Oh. I see.
I'm reading it for statistics and data mining
like what?
Idk if I did that right
I did probably
Start:
Chem kinetics
Chemical kinematics 
sounds about right.
,rotate
who know what is the name of that software that is used to writing a Equations and it starts with C
Clatex
If it's not latex then not worth
I'm kinda impressed lol
What's your new handwriting now
?
I'm not up for speaking Arabic with you
It's an English server
@ocean harbor Can you help me with math
!help
To ask for mathematics help on this server, please open your own help channel or help thread. See #❓how-to-get-help for instructions.
Huh?
This is my handwriting now

Haha
"That's my handwriting since three years"
Yeah so?
I did say since
Oke oke
,rccw

Average Krebs cycle enjoyer
Haiii
@ocean harbor
Nice
i glanced at “Oxaloacetate” and thought it was hexadecimal lol
anything that starts with something that looks like “0xa” is hexadecimal
What?

yo
yoyo
huh??
this is probably the other Akira

i think im the fake akira because their join date is older than mine
I mean
many people named that name so it's normal

Haha but this akira is less popular
lol
whats up
who tryna play some chess
how good r u at chess
XD
wbu
no you dont need an account
W
2 years
what elo do you have rn
ahh
lichess is good
fr
bruh i hate when people think they’re smart if they’re good at chess
lmao
cus like yeah, if you’re good at it you have good critical thinking skills but theres a lot of memorization
true
have u ever used haskell
no
isn't that a coding thing?
yeah
dysfunctional programming language
different from python and all that trendy ones
XD
r you guys in hs?
fuck my teacher
you guys take cs?
ye like almost 6th year being in hs
since my school doesnt teach anything
damn
i remember doing wordpress in my computer class dude
i tried learning python but all i learned was the print thing and i never got to doing anything else
i mean the most i did was make like a very basic calculator that could add
i did pretty well in cpp last year so i decided to take the other one, which requires for a uni im attending it
do a web scraper
but i dont remember any of the inputs that i did for it
like download libraries
it's way different
duuuuuude
i still dont get why ur uni requires a programming language
cs major
ya but
whats cpp?
but yeah you're right actually
C++
college prep programming?
its a programming language
o
CS is literally 70% math
i dont even know if i will ever get to use
a programming language
dude if u think about it
bro im new to cs ok 😭
it's a coding language
ik what c++ is i just never heard of it referred to as cpp
all good
you just google
im open to that if you can
im in 11th grade
nice
2007?
bruh 11th grade is 2006 i think
i see
ur in hs so its ok
gap year
i mean after i get out of hs im still gonna be a big kid
same
I feel so old reading this
are you 90’s
XD
u kidding? not that old
we would have to salute if that was the case
💀
mi gonna search how haskell code looks like
try c#
LOL
or js
dude

can you not call me a "dude"
i apologize
tbh, they are
what do people use func programming for anyway
agreed. Java is shit
it doesn't have side effects (most of the time), which means you know precisely what your program does, and it's very hard to fuck it up.
i see
It's crucial when you want to be absolutely sure that it's correct. Say you write a software for an aeroplane, or a radiation machine, or a trading bot
Curry-Howard correspondence makes a natural link between the program and the logic, so you can even prove that it's correct
But tbh, it's shit if you are not used to it
dud eim gonna become a haskeller
It is, much more than other programming paradigm
Haha pls don't say Java is shit it was first programming language i learnt
I found it kinda nice as starter
im saying it's shit because my teacher makes it shit
he's not accepting the stuff im doing because they're way better than theirs
Oops your teacher is cruel 💀
yeah fuck him
Ooh it must be frustrating
is he bald?
sorta
Sorry I pinged you by mistake...
No worries
Yeah this user ^^
Im not remembering all of your names
smh
I have one name... And that's Muhammad
You're always gonna find me by my name
well i have to remember the correct spelling
ik many people named muhammad i had in my middle school
Pretty easy once you've written it few times
yeah but there’s different spellings
Yeah obv
Im Muhammad.
You'll probably forget me anyway
cool cool
But yeah
My names mohammed I use a o idk why just did

i have seen that before
I see
don't you hate like when people doesn't spell your name correctly?
I hope you're not asking me
i mean his name is right there
I'm not answering that
You should know the answer
;-;
I think I said it.
well technically i hate when people doesn't spell my name correctly
not in online
irl


That I hate it
I found these things way better than my teacher's things @neat lintel
Anyway let me go now
bye
So good ain't it lol
Typical?
mhm
So good to say bye aye?
ye
Woahh these are actually really nice , why doesn't your teacher accept it literally
The way we used to light our childhood life.
because he's literally sucks
When there were no backups
It's amazin
The backup finished during dinner
And we're in a blackout for the next two days
Damn bad luck why dont you complain
idk
I'm happy I was on the dev team in HS and didn't have problems in the comp sci lab
Fr i am sorry to hear that you have to handle such a teacher
I was on the dev team since grade 7 so
I loved JavaScript for a reason lol
Okay nvm ded chat
Ded ppl
Ppl def lurk here
Huh
hi
im dying in java
Good
It's good
nah fuck it
Okay?
Give me a complex number part of the Mandelbrot set
Uh
I dont love it that much
isnt it like z=
idk
Fake love exposed.
i forgot the equation
Thankyou.
i dont understand a thing about how it actually works
i just know its infinitely repeating patterns
Oh yeah well
So it's basically
The set of all c
Satisfying the fact that
z_n+1 = z_n^2 + c where z_1=0 converges
third
reason:CS
hi!
Hi
lmfao
So for the Mandelbrot set
I don't know I just do 100 iterations
And made that pfp for myself
I tried a 10000px by 10000px one which only amukh saw
kabo is not a person
Idk it's there so I asked
python 
i couldnt do it
Akira

the extension'll be .ak
does this syntax look bad @ocean harbor
How about .akira so it sounds like a virus
not much
i have two problems with it
one you need to call with ( and ) around the expr
if your function is the expr
and two you need to deref it 💀
i bet i'd be terrible at this language
ima failure 😭
also what language is this
yeah because it is super hard to use
it means welcome
Oh
oh i see
I see
dec main() -> int;
def main() -> int {
// n_char:char* = malloc(4);
// k_char:char* = malloc(4);
// gets(k_char);
// gets(n_char);
// n:int = atoi(n_char);
// k:int = atoi(k_char);
n_ptr:int* = malloc(4)->(int*);
k_ptr:int* = malloc(4)->(int*);
scanf("%d, %d", k_ptr, n_ptr);
k:int = *k_ptr;
n:int = *n_ptr;
printf("%d mod %d = ", k, n);
// return k mod n
r:int = 0;
i:int = k;
goto while;
label while:
if (i == 0) -> {
goto end;
}
if(r == (n - 1)) -> {
(ptr r) = 0;
(ptr i) = i - 1;
goto while;
}
(ptr r) = r + 1;
(ptr i) = i - 1;
goto while;
label end:
printf("%d\n", r);
return 0;
}```
all this
for k % n
all it does is compute modulos 😭

it just has a variable at 0, and increments it k times, but every time it hits n it just goes back to zero
for k mod n
i don't know much about this language
😭
its not language-specific
that algorithm is just english
this is just my implementation
damn ok
inspired by python
it was a joke
I haven't used .py in months
only .js
and .math , .chem , .phy and .bio
ok
why not use modulo operator??
why would u need to implement it
you can also just use something like int x =1; bool isEven = (x & 1); or something
not sure if right hand side for AND would be 1 tho tbh
Is this C ??? what's up with malloc
cant be C the syntax is completely different
yo does anyone know what is a good physics help server?
thhxx!!
np
I am about to go back to college for my bachelors in Cyber Security. Last time I was in college (12 years ago) I failed took 2 remedial math courses and failed the third 3 times. I have to take Topics for Mathematical Literacy for this cyber security degree. Does anyone know what all that entails?
You should check the syllabus. How are we supposed to know?
I'm not enrolled in the class yet so I can't access the syllabus. I was just wondering if anyone else had taken something similar and was willing to share some basics
I think it varies between unis, there's no way to tell
Unless it's something super common, then idk
I googled and it looks like its called Math 105 at several colleges.
I'm just trying to calm my soul over here. I never took algebra in high school so I'm really worried Im gonna be in over my head
I just went and got my old college math books so I can at least brush up on what I passed.
this doesn't tell us much
Thats all the information I have. lol. Topics for Mathematical Literacy
This is how bad at math I am, I can't even formulate a question about math correctly
If you are this bad at math, and you got successfully registered for this course, it's probably not so bad
They haven't done any testing yet. It's an online college. I'm not registered for that class yet either, didn't wanna try it my first semester back.
I appreciate your thoughts though
We weren't here 12 years ago, but we are all here now if you ever need help. We might not know all the answers, but I'm sure we're decent at math enough to help you.
Some basics: https://assets.openstax.org/oscms-prodcms/media/documents/College-Algebra-2e-WEB.pdf ( up to chapter 7 )
I went and picked up my old math books and am re-teaching myself multiplication for the love of God.
I figure I better go over these books now before I get overwhelmed taking classes starting January.
Just wait till you get to division 
Oh I see it coming up in the book. I'm not looking forward to it.
quotient groups
I ran thru the first 8 chapter of this basic math book, was a bit more basic than I needed but it was good to brush up on some definitions and whatnot.
I am officially done for the night
Ugh me. Im looking forward to some of the answers you may get.
I think re-learning topics that they’re not sure or topics that they felt insecure about is a good way (starting from topics they’re comfortable with)
That's essentially life of a PhD
And on top of that is the pressure to find something publishable. First paper is always the hardest.
trained themselves to be miserable doing math
life of a PhD
This one cut so deep it changed \pi_0(catscradłe)

is a phd worth it?
I mean, one can get into stats or cs and can be really well paid
(I should maybe brace myself of the incoming bombs sweaty math nerds are gonna drop at me)
a phd for money doesnt sound like a good motivation to me
Um yes it does

this blue emote is so weird
I have heard from no phd student they're doing it to earn more.
Depends on industry
And I think its asinine to do such a thing
Certainly with regards to mathematics at least
and admittedly more on the specific economy
i do math for the funsies
uh well even then frankly i don't think math phd would help you make more money
i don't think i can devote 4 years of my life towards a phd
Is it interesting to u?
maybe idk
Idk man but like there are other ways to make money too
we will see ig
it's too early for me to ponder on this
no it aint
I will learn and absorb as much as I can for now
Ok
Goodluck lol
I can feel the money pain
you too
I promise if it's not something you enjoy immersing yourself in you will hate yourself for doing a phd
Join hu instead :]
Phd or master’s programs in math finance or quant math do make you more money doe
i did this with physicsand got over it by stopped doing physics
But at the same time you have to enjoy doing that sort of thing
yeah im acc way more active inhere than in step
i got lucky that i had hps as a glowing exit door out from physics
Can you guys suggest me some good topics(more obscured ones) to self study which only has minimal prerequisites like Real Anal, Abstract + Linear Algebra . For example graph theory, information theory, game theory, Number theory etc










rats everywhere 🙄
expecting minimal prerequisites in number theory might disappoint you
graph theory is probably the best suggestion, maybe some parts of combinatorics
No cats
But I'll come to the rescue
With Akira-uncertified Pallas's cats
;-;
Go away. You're ewwh
So hurtful 😭
You're gross.
I wanted to take that honey
And you're such ew.

what are math forums you guys would recommend?
Yeah true but basic nt like the ones that appear in mathematical contests don't
Do you have more suggestions 
hallo
lmao what
topics in nt classes?
topics in nt? Are you referring to the course titled as "topics in nt" . I didn't get you
What suggestions are you looking for?
Something which doesn't appear normally in undergraduate as core courses
combinatorics?
Umm I have done a good part of it so I am looking for more of them
Yeah like except for courses like functional analysis which fall under core /mandatory courses
because algorithms, graph theory, scientific computing show up in CS curriculum and are interesting
I have done a good part of algorithms and graph theory
have you learned anything about automata theory?
Because then they would start demanding more advanced maths
No
that isnt necessarily how learning topics goes
Yeah I agree but it does happen in general
For example more advance graph theory needed some advance linear algebra
Ok I'll check it out
to my knowledge linear algebra is one of those fields that doesnt really get more advanced
most of what you learn in a ug class is all thats needed, its just that how things get applied can be interesting and unexpected
also people generalize some things, but mostly everything stays the same
Interesting
Sure it does
it does get very advanced :)
Yeah but when it gets advanced enough we call it "functional analysis" or something
nah
if you stick strictly to linear algebra as study of vector spaces, modules over a field
then the cool stuff comes from generalizing and adding more structures
like functional analysis
I think it goes more wide than deep at that point if you get me
Not even that
There are a lot of detailed topics in linear algebra that are important in various settings and which a lot of people don't know necessarily
all I can think about is spectral theory stuff
But it's less "all these topics build on each other" and more "more and more things"
other than that I really don't know what detailed topics you mean
and possibly computational things
Vandermonde matrices, circulant matrices, orthogonal polynomials, Perron-Frobenius theory, matrix decompositions, numerical algorithms, tridiagonal stuff, etc
but when i think finite dim linear algebra I think its mostly solved
It's often that you have examples of matrices that are important in particular settings, and you don't necessarily just want to know that you can hypothetically put any matrix into Jordan form
there's still ongoing research in like non-negative matrix factorization and tensor factorizations
what is non-negative factorization?
factorization of a matrix into a product of two matrices with non-negative entries
how do you go about researching these things
my assumption would be that you attempt to find algorithms
because thats my assumption about linear algebra research. its mostly finding algorithms for specific cases for things
yes but in the process you may want to come up with new linear spaces that could be useful and such
wdym new linear spaces?
a lot of krylov algorithms are called that because of their reliance on krylov space
like come up with a linear space that describes the problem well and that allows for easier analysis
oh thats cool
im only aware of ongoing linear algebra research because I took a computational LA class
before that ive had profs tell me that its not like new theorems are coming out and reshaping the field
Yeah there aren't gonna be a ton of new theorems of the form "Every matrix is blah"
so my assumption is that most of the research is just computational because thats all ive seen
It's more as I said, detailed topics that matter in certain settings, also computational stuff
Yeah that seems to be big in algebraic combinatorics
Sure but in group theory you don't get a ton of new "every group is blah" type theorems anymore either, in ring theory there's not really any new "every ring is XYZ", etc. but it's not like group theory or ring theory aren't deep
generalized eigenvalue stuff also pretty cool :)
but you want your matrices to be sufficiently 'nice' for that sorta stuff
cough Jacobi conjecture cough
cough harder Grothendieck's inequallity cough harder
you seemed to miss the point of the entire conversation earlier
Ug class is merely the equivalent of knowing how to do basic operations. Pick up some heavy Olympiad problems, you'll find an insane amount of theory involved
@alpine comet Can you explain how what you said is a direct reply of what I wrote in that you read my message and replied to something in it?
You said Linear Algebra didn't get more advanced, and I disagreed to that
Did you read anything below?
Like the message you just replied to?
My main point was really this #serious-discussion message
there are some "Every random matrix is almost surely blag". Random matrix theory is fast-growing
You are preaching to a choir
Maybe not reshaping the fields, but there are central questions that are stupidly simple to state yet still open, like Jacobi conjecture for example. To say it's solved is a gross overstatement.
Sure, it's a field we know the most about compared to other fields, but doesn't mean it's over
I disagree to both of these statements

you don't have an external nuclear energy source to run your quantum supercomputer running DesmOS? 😱
Well tell that to the government
damn gov't trying to regulate isotopes
They decided to scrap our power
Since we didn't let them use our supercomputer for their 'defense' purposes
Well basically complex 2 is working but
I don't have access to complex 2
I think I should make my profile DesmOS compatible
bummer

lmaoooooo
Idk who needed oil for a transformer at home
Now they just got the whole area in darkness for the last four days
Oil in Transformers is cool physics
that'll probably last longer than you think

You're bad.
You could wish our transformer a speedy recovery but no

Is there anyone whos a late high schooler looking to study math ?
I’m working on a project and would like some input
Yr 12
What is it
Maybe 11
I’m writing a text on the math major, because I always found videos on the topic in hs quite unsatisfying
The subject descriptions were always superficial
I am writing a text that explains what all the subjects are and why they are studied and I was wondering
How many pages of content to give a satisfactory answer
@split pawn Hi
Uninvited guests are not allowed to converse with Muhammad
I want to be able to do each subject justice and give it a good introduction so a high schooler can understand what it’s about but I don’t want to write a textbook

I don't have my PC
So I can't really talk there
Cause I can't type due to the cold on my mobile
its fine
im using my parents laptop and my hands are also cold
still i text
meow
still
my hands are cold
during my leadership or cs class i text on phone
they were also cold

Well I can't bear too much cole
Cold
Maybe you can keep up with the chat
I can't.
Also I don't text during class so.
Hot tea.
Is fun to take in the cold.

no
no

Yeah. Same thing.
because we go different timezones
Yep so?
For me, it's not.
The current time for kensukeken is 10:18 PM (EST) on Mon, 13/11/2023.
this code does the most simple thing
but it is redicuously comolex
wtf is thing->(int*)
lol now i need to try some graph algorithms
can’t you do (int)(1.2)
G->edges is getting a pointer to the member edges from the object G
what the fuck kind of operator overload is that 
then i cast it to an int, perform pointer arithmetic and then convert back into a int*
wdym operator overload
this is for the first level, since it is a 2d array
-> is for accessing members of a pointer in my eyes
yeah
so basically
i use -> everywhere
expr->(type) is a cast
struct->member is a pointer to the member
it does not de ref struct and get the member, it gets the member and gets a pointer to it
you use -> to declare a function, and you use -> for all control flow stuff
so like if statements, while loops, for loops
so bascially
does (type)expr behave identically to expr->(type)?
yeah idk why i did this
almost
for basic stuff it does
but like (type)expr is a pretty risky cast
wait this is your own language?
since it kinda interprets
ye
oh…
the c-style cast interprets what kind of cast it should behave as
mine only has 3 levels so far
bitcast, ptr_to_int, and int_to_ptr
thats all i need so far
the language runs tho
prints the graph
lol whats even worse
i thought & was ugly so i replaced it with even more ugly "ptr"
*(ptr x)
i mean its alr actually

So I'm working on this lab which is really hard, and my lab partner just solved everything. The thing is I hate to be carried, or be useless because I hate people that are like that when they work with me. And also because my lab partner said we should go with their idea, I dropped mine and tried hard to think the way my lab partner thinks. Anyways I feel useless is the point.
What language is this
My own
For now it is pretty terrible
Oh I see
That picture is from tests/graphs.luci
Something like "printf" reminds me of cpp
Yeah I am using the C std library

sure
Akira E-Girl
that's an improper integral
Akira E-Girl
What about this

hmm, can you do this without using complex analysis?
maybe if you plug in a parameter and differentiate
this is cute

i think the best way to handle that
hmm
is to integrate by parts, 1 * arctan(x)
then you get x/(1 + x^2) which should be handleable
There are easy integral exercises all over the internet
If you want something specific to your level of ability, it would be best to use the internet to search rather than have us bogosort integrals

makes sense
This is like the main application of complex analysis. Write cos(x) as real part of e^ix, turn everything into a complex integral and then use complex analysis to evaluate in just few steps.
In fact, more generally, for any sufficiently nice (say ( L^1 \cap C)) (R ) with no poles on ( \mathbb{R}) and finitely many on (\mathbb{C}), we have
[ \int_{\mathbb{R}} R(x) e^{ix} = 2 \pi i \sum_{y > 0} {\rm Res,}(R(z) e^{iz} ) ]
provided ( \lvert R(z) \rvert \leq M \lvert z \rvert^{-p}) for some (M,p > 0) and ( \lvert z \rvert \gg 1 ) where we use the semicircle contour.
