my best exam score ever was when i went to the bathroom twice before it (and it was a 3 hour exam)
HELP š
then i really gotta take that advice lol
worth a try š
another thing is don't get stuck on questions. do easy ones first, skip/guess hard ones to start
Wat
my HS was part of the pilor program to take the ACT virtually rather than on paper
Weirdge
i'd be surprised if that is not the case...
200k collegeless mfs trying to feel smart joining a math discord server
you also joined 
hey, it worked for me
I've even fooled them into believing I have a PhD, the rubes

Hey is there anyone here that knows statistics
I just wanna ask about probability distribution
which ones?
Idk the base level high school one?
so binomial and normal, etc?
Oh yeah that
oh okay what's your question?
I'm looking at my module here, there's a word problem that goes something like a guy draws 2 balls out of a bag with 5 orange balls and 6 violet balls
Then there's tables for the probability distribution
i think you need to open a help channel instead
if it's a problem you're stuck on
But it looks like it just ignores the fact that you're more likely to draw a violet ball?
Is that not a thing you account for?
do the balls get replaced?
ah okay, why would you be more likely to draw a violent ball? Have you seen a tree diagram before
Because there's more violet balls?
think of it like this. For the first event (first ball you pick), probability of getting violet balls is 6/11 and probability of getting orange balls is 5/11. If you picked violet ball first, what would the probability be for picking it a second time?
Yep, the probability changes
It changes depending on what occurs on the first event
Wait I think I'm getting it
So because I'm drawing more than 1 ball, the excess balls decrease and the chances are evened out
yep, if you were drawing only one ball, than yes drawing a violet ball is always going to be a higher chance than drawing an orange ball
But you're doing it twice
we do have a #probability-statistics channel, by the way
Technically I do have homework similar to this but I'd just like you to confirm that it's a similar principle
Ah okay
yeah it's similar principle
i mean discussion 2 is pretty dead sometimes lol
And #discussion
eh yeah, but it depends on the timing tbh
for me it's near afternoon, but for others it's probably 2am or smth
it's 11:49 for me

I'm assuming you are talking about the removal of gender ideology extremism from places they shouldn't be...... and/or the criminals waltzing into the country by the masses?

Youāre genuinely off the deep end. I say this with genuine concern, you are fully indoctrinated and are not looking at things objectively
None of what you have just said is true, itās just the nonsense parroted by far right grifters
I lean center-right, mainly because of my economic beliefs. Nothing I've said is extreme or unreasonable yet people love to resort to strawman arguments š¹
I mean
what do you call "gender ideology extermism"
like what does that mean to you
have you seen any evidence of these types of behaviours actually happening through video or similar means
Or did you just hear it from some news anchor?
because it just sounds like you're parroting the stuff that like
fox news anchors say
What is gender ideology extremism
what does this mean
also that isn't what would usually be called a strawman argument š
what is a strawman argument
the idea is that you sidetrack an argument with a wholly unrelated point to the discussion, argue against that secondary less relevant point and then pretend like you won the argument
ben shapiro and gang do that a lot

that expresssion was my reaction to the question 
Oops, I thought it was possible to have a sensible discussion with this guy, but then I looked at his history š
uh yeah... what the actual fuck
yeah, but like what does it mean
girl i dunno
apparently i make a lot of exaggerated facial expressions without realising
irl, that is
i was saying if you cross the border illegally you are a criminal. simple really.
do you not agree?
so lets just open the borders
Sure!
let el salvador in let venezuela in
Why not
sanest leftist
I mean, ignoring the fact that that's not actually my position, you should probably explain why you think that way instead of just calling me things
it's just an overreach of gender-related policies, and I label it extremist when it's being pushed on children, and to a lesser extent institutions in general
because why are you arguing against biology in a situation where it matters
What is the overreach you speak of?
Yeah supporting children's choices is "pushing it" on them.
Because open a fucking first semester soc book to realize this not what anybody means by gender.
why are children allowed to make these kinds of decesions
They usually have to have the consent of their parents?
It is quite literally child abuse to influence a child into taking HRT
Why are they not?
Then their parents are terrible parents
nonetheless
Nobody is saying "influence them"
I don';t
Turn off the tucker carlson bud
They don't have children taking HRT, they put them on puberty blockers first if anything
It's the same as any other medical procedure where there's risks involved
So this should be socially acceptable?
Yeah?
oh no
mind you this IS irreversible
Literally talk to fucking anybody in the camp of folks you seem to have a problem with so you can even know what you're arguing against rather than making up the dumbest straw man args
doot can you just ban this guy for transphobia
They just delay puberty
I'm not transphobic
they actually technically are, but it's a fine point
as a trans person i'm saying you are
On an individual level an adult can make any decision they want
Seems pretty transphobic to me when you're calling letting people choose their own identity and have that be respected "gender extremism"
Do you like people being respectful of you?
societally, my opinion is that is it is destructive
mind you i am not transphobic or homophobic
So why is this any different from other medical procedures that parents can consent for their kids to undergo?
disclaimer
Doctors don't just do this willy nilly
disclaimer***
i'm a trans teen and i really want hrt like really really bad because it would make me happy
Like there are other hormone treatments and things that you can make a decision on whether you do or not
Like HGH treatment
I understand you have gender dysphoria and you think this is somehow the solution
its not
Majority regret it
suicide rates increase
Do you know this person?
these are just plain lies
they do if i could send links i would back it up
you can send links
If you don't know somebody don't give them medical advice.
You are spreading delusion
claiming you are not transphobic doesnāt make you not transphobic 
bye
So the facts magically don't count when they hurt your feelings?
Banned

These type of people are so jarring
What a piece of shit
I genuinely do not know how they function in life
What's weird is that this isn't an uncommon behavior or attitude
its sad that there are people that actually believe this
^^
Well I mean
me when im wrong about everything to own the libs

Sorry I should have just banned sooner
what a trainwreck
Iām having increasingly negative thoughts about people like that which is why I chose to make a very diplomatic comment then dip
it's fine, i don't really care, i deal with these people all the time lol
Like
Having access to the internet is nice
When you know how to use it...
Also "you're speedrunning delusion" lmao
āSuicide rates increaseā (apart from the fact thatās not true) I fucking wonder why, couldnāt be related to miserable bastards like you making peoples lives hell for no reason what so ever
I also like how it's always "to protect children" but they can't see that they themself are pushing their own beliefs on kids
The only "speedrun" I see with these type of conversations is how fast it takes them to be like "nuh uh the facts are wrong and the science is wrong and uhhhh basically yeah"
These folks just make me mad
Because they don't actually care about protecting children
now how long until they make an alt and come back
The actual hypocrisy of believing we ought to respect the gender identities of kids but not unless they conform to same made up bullshit is stupid.
"Respect my kids gender but idgaf about yours" level thinking.
Incredibly so, and itās not even just the transphobia thing which obviously pisses me off, but the way he talks about āillegalsā and the shit that (mostly Americans) will justify doing to āillegalsā now is fucking sickening
Also the fact they thought they're center right 
What the fuck is far right in their eyes geez
I genuinely fear for our near future with the rise of fascism and the far right in the west
My outlook on the future is becoming more and more bleak tbh, every time I see anyone like that
The latest was Trump crashing our national economy so that some S tier insider trading could occur
What drives me up the wall is all the people who vote against their own material interests
Honestly, in comparison to sending anyone he doesnāt like to prisons in El Salvador, I donāt actually care about that
and stay deluded about the fact that they've done so
I like to imagine these people are the minority
The ones fully dedicated to trump
Or they're too young to vote
Most people are kinda stupid and don't really care too much about party lines and will just vote for the guy they think will help them with their taxes and inflation
Like I don't think most people support trump that much after the whole stock market fiasco and the tariffs increasing prices of stuff
Obviously I do care about it, and it pisses me off to see everything saying trumps brought about the best day in the stock market since 2008 piss me off with their lack of critical thinking skills, but itās just the loss of humanity thatās upsetting me
Mark my words that person will figure out they're gay and or trans in like 2 years
How many people are willing to justify utterly reprehensible acts on whoever Fox News or whatever other right wing shit rag they engage with tells them to
lol
I kinda don't think people are THAT stupid per se generally
They're just ignorant sheep
Yes, but they've been sold that there's some culture war going on and as a result see people who don't buy into the nonsense as the enemy
what happened :hollow:
So they tend to double down on their ignorance
transphobe got banned
ok ima stay out of this convo š
It's kinda horrible how prevolent media illiteracy is

That's what happens when it's owned by capitalists who don't have anybody's best interests in mind

<@&268886789983436800> asking users to pirate papers for them

?
Due to the discord tos we can't allow discussing piracy on the server
I apologise
My thought was short
No problem. I was just figuring you didn't know.
I was about to teach him how to do them
TOS says you can't share homework??
Neither of you are currently banned so I gave you the benefit of the doubt. No worries lmao.
This was regarding a different issue.
Uh okay
Oh. All I did was offering to teach him for free
Yep no worries
So am I allowed to teach him
@wary fern gonna respond here because it's not really a tcs centric topic. I joined out of high school at 18. I was able to use the GI bill to go to college. This was effectively the only way I would have been able to go to college in a serious way. It was successful in that sense.
For actual being in there were some things I liked and some things I didn't like. I mean, the military is what it is. The jobs can be serious. Being enlisted means you're basically at the bottom of the totem-pole. Which means you end up doing a decent amount of garbage jobs that suck.
A lot of ncos and officers are cunts
A lot of junior enlisted are morons
It shouldn't be surprising that it is that way.
I'm not going to tell you whether it is or isn't. I finished my enlistment. I paid for college that way. I doubt it's the most optimal or direct way. It worked for me. It's really hard to know in retrospect whether big choices like this are right.
The ethical concerns people mention exist and are worthy of consideration. I think that deserves serious thought.
I think it also deserves some serious thought as far as whether you are able/willing to deal with a lot of dumb assholes for 4-ish years.
I wouldn't call it terrible either. If you stay out of trouble you eventually figure things out. It's steady work. The pay is reasonable. The benefits decent too.
Just don't make whatever decisions you make lightly. If you go that route it's going to be something that will be part of who you are for a very long time.
@wild lantern ?
None of my business
Then Iāll take it as a yes
@static hazel Whatever questions you have drop in my dms and Iāll teach you how to do them

What's up
how you holding up? 
Its been good the past couple weeks. We haven't had much to do so we do saikang (mandane work) from time to time and just rest in bunk the other times LOL
Morning nap + afternoon nap 
Of course, I did self-studying 
Analysis and lin alg slapping me as always šæ
Btw I found a new formula
For ax+b=0
Where a=/=0
Use this formula to solve for x
[x=-b/a]
Ex. 3x+7=0
Using x=-b/a
x=-7/3
Ex. 2
4x+10=6x+6
0=2x-4
x=4/2=2
what sense of the word "new" are you using here?
I discovered a new formula on my memory
And i thought no one else knew about it
And how did you come to this conclusion
No one have done it in practice
By which authority
Youtube, math teachers, and proffessers
i don't think that's a new formula though. You're just rearranging it to solve for x which everyone does
You queried the entirety of youtube, asked every math teacher and professor on this planet?
New formula For my memory
Just local only
how local are we talking about?
Would there happen to be no local teachers and professors
Helpful if u suck at basic Algebra
City
Expand until sufficient
But why memorise that formula if it's just rerranging to find x?
I highly doubt none you asked did not know of your stated rearrangement
It for memory learners, formula lovers, and people who don't get rearranging x
but maths isn't just for memory learning though.........
This is a surprisingly uncommon point of view
They are required to take Algebra classes tho...
hmm, i get what you mean. I suppose as long as you recognise where x = -b/a comes from than yeah it would be helpful
Ye
In general it's neat that you discovered this pattern, it's just that it's not something new that hasn't been known before
Yeah that's what i was thinking, it wasn't new, but still neat
10m+ people are trying the same thing
really? Well idk much about general maths education, so it's not like i can have a say in this
I mean, I agree with you that mathematics shouldn't be about memorization, but a lot of students (and teachers, sadly) approach it that way
Oh okay, i might have read it wrong a bit lol
Also I found a nice non integer approximation for x!
They are Stirling function: sqrt(2Ļn)(n/e)^n
And my function:
floor(n)!(n^(n mod 1))
Note: floor(n)! Will output any integer, regardless of if n e R
Check on desmos to see which one u like
Is real analysis the hardest course in colleges?
There isn't a ranking and it's subjective, but on the whole it is considered fairly hard by many
I really hope things got a bit easier when I get to abstract alg
We have a #real-complex-analysis channel by the way, so you can ask questions there

i mean its literally the quadratic formula for linears
linear formula, if you will
but no one calls it that because one rearrangement brings you there
While memorising the quadratic formula might be handy, if you find it easier to remember a formula to find the root of linear equations than rearrange, then 
I'm reminded of Al-Khwarizmi's work on quadratic equations; that was before negative numbers were a thing (or at least before they were a mainstream thing), so he considered six different types (https://en.wikipedia.org/wiki/Al-Khwarizmi):
Al-KhwÄrizmÄ«'s method of solving linear and quadratic equations worked by first reducing the equation to one of six standard forms (where b and c are positive integers)
squares equal roots (ax^2 = bx) squares equal number (ax^2 = c) roots equal number (bx = c) squares and roots equal number (ax^2 + bx = c) squares and number equal roots (ax^2 + c = bx) roots and number equal squares (bx + c = ax^2)

This.
My first semester I took discrete maths and it felt like the most difficult course ever lol. Once you adapt to the new learning style then it becomes much easier.
You are forced to become very independent very quickly if you want to survive lol
same, there was a lot of reading and learning how to write proofs. It was kind of a shock to me lol
i donāt know anything about whether any of the islamic algebraists or earlier explicitly used negatives, but karen parshall has a very interesting article aptly titled āa plurality of algebrasā that describes the rather confusing situation of algebra in europe in the timespan ~1200ā1600, she explains therein for example how Antonio deāMazzinghi did use negative numbers in the 1300s, and his work did have some influence, but exemplifies one of multiple schools of thought that would ultimately fade away
@coarse bridge some guy found the solution of 10,958 in a certain pattern of rules

Bayesā Theorem ā Thomas Bayes
P(A|B) = \frac{P(B|A) \cdot P(A)}{P(B)}
This theorem describes the probability of an event, based on prior knowledge of related events.

1 teaspoon vanilla extract

2/3 cup sour cream
2/3 cup heavy cream
i donāt know how to make cheesecake
Thank you!
I mean, that's not really a recipe, just a list of ingredients
But close enough
ye i wasnāt gonna put the whole thing in chat
I can make cheesecake so I can get going with the ingredients alone
lol
weird flex but ok
What's weird about it? It's a skill I have; it's not particularly impressive, I'll grant you.
I can also make kouign-amann and sourdough bread, which I think is quite impressive, if I say so myself
......
I see my power has you speechless
Sourdough is not that impressive imo, a sourdough starter is basically like a very undemanding pet that you only need to feed once a day and you can put in the freezer for weeks at a time
Yep, it's the bread itself that I find more impressive
wait no but don'
don't leave us with the question :c
Unrelatedly but yeah, people discuss sourdough starter like keeping it was some kind of sacred, arcane art.
It's just flour, water and some microorganisms, once you get it going you have to actively try to kill it off
Yeah, it almost feels like cheating. Like, there's yeast and stuff in the air, I can just put some flour and water on the counter and forget about it? 
evey time I open this server it's always yeast
Can i have a recipe for yeast than?
Depends on where you live
bro is this yeast cult

hi, is anybody familiar with the ORFE department of the Princeton uni? Specifically about the phd program
"10,958 problem" by numberphille
can you link to the solution?
Search up 10,958 solution
yeah i mean i did, a lot of old stuff comes up
Ok
Ik
perhaps im confused, i thought you were saying there had been a recent new solution found ? were you just refering to matt's original solution forever ago
yeah refering
oh ok
Btw I found another formula i discovered
For ax+b=cx+d
x=(d-b)/(a-c)
Where a-c=/=0
Use this formula to solve for x
ex. 4x - 7 = 2x + 11
(11-(-7))/(4-2)
(18)/(2)
x = 9
4x - 7 = 2x + 11
2x - 7 = 11
2x = 18
x = 9

why did you @mighty pilot #discussion ?
You can grow yeast using petri dishes, agar-agar, some flour? some medical tape, an aquarium heater, a big enclosed container with water, and a autoclave ^^
You pingged me
oh thank you what a lifesaver
sorry, I thought that the joke would be funny
couldn't other molds grow too?
Yeah thatās why you need to sterilize etc. But for making sake they used a different method with koji-kin which might be more efficient. Anyway itās yeast, how hard can it be?
I guess if you donāt need to do a big collection of different kinds of yeasts you might not need all that
Sourdough starter is a specific combination of yeast and lactic acid bacteria, and once you get the cultures going (which does require some care in the very initial stages), they will basically reach a kind of equilibrium that will also prevent other microorganisms from getting in.
I don't know how and whether people cultivate yeast alone in non-professional settings, if I need yeast only, I just buy them.
I might check. It might be similar to the āfermentā (flour+yeast+water in a bocal) that you prepare a week or more in advance before mixing it with dough
Feel itās the most convenient way short term
sourdough seems so finicky but it's quite delicious
my aunt makes alot of sourdough
she also uses some of the sourdough starter to make naan which turns out fantastic
sourdough is yummy
Nice but itās likely you werenāt the first to
given thereās like 8.5billion people in the world
Exclude the illiterate people
Sourdough starter is finicky for like the first 3-5 days
I see
Making sourdough bread is finicky if you want a freeform rather than tinned loaf, but then it's because of the form factor rather than sourdough itself, freeform loaves are tricky on the whole.
But the starter, once established, is quite resilient.
I have ADHD so as a result I forget to feed my starter for weeks on end, and it revives just fine (I do keep it in the fridge during those intervals, though)
Well, making sourdough bread could also be said to be finicky inasmuch as the process does take quite a lot of time from start to finish, but most of that is just waiting.
But you can't just decide "I want some sourdough bread" and have a loaf within like an hour or two
Need to plan in advance
And sourdough bakes do take longer to prove (grow) than ones with commercial yeast
looks like ur not going to survive if i throw you into the wild!

im in high school and the more i learn math and physics the more i think math is more intuitive
any opinions about this?
intuition leads one astray
so you mean, my aptitude is very likely to be mathematics?
ashtray?
I don't see a definition here
you havent seen enough math to witness horrors
the jordan curve theorem meme posted above is one such example
because the proof is not so simple despite it being something you intuit to be true
every vector space has a basis
ik that but physics seems way harder for me
less interesting also
It's just another homology proof no?
I mean, that is true
Meanwhile not every separable Banach space has a Schauder basis, even though it really sounds like they should
And I always misremember that problem as the one for which Enflo was awarded a live goose, but that was for another thing.
I wish the Clay Institute had been courageous enough to make the awards livestock rather than boring cash

Thanks president trump
this is why I think we need to change definition of basis cause space with infinite basis is basically useless
I think whole point of linear algebra is that we have finite basis
I mean there exist very important infinite dimensional vector spaces
Like what
P(R)
Idk what that is but from my lens (applications) having a space where I can't use 90% of tools of linear algebra is useless
the set of (infinitely) differentiable functions from R to R falls under this category
clearly not a useless space
I don't have to use tools of linear algebra for that
systems of linear odes?
no
youre disparaging infinite dimensional vector spaces because of your own unfamiliarity with them
I don't have to know them to tell finite dimensional speces is much more useful
you have zero ground to say this if you dont even know what theyre used for
ok obviously there is HUGE difference between finite dimensional and infinite dimensional spaces
Yeah sure bro
You just want to argue
Yep
The literal "fundamental theorem of linear algebra" doesn't work for infinite dimensional spaces
What is even point of considering it same thing as space with finite basis
Things would be so simpler if we just said basis is something that's only finite and here are things you can use with it
You can use the remaining bits and pieces of linear algebra for other things
cool? there's other theorems
it just seems weird ot me that you're this gung ho about it with such a limited view on it
Why do you think definition exists in math
i dont see how the definition affects anything with finite dimensional spaces
I have good view on linear algebra
And what it is
it makes simpler
That's the only thing I'm saying
Not that infinite dimensional spaces are never used or anything
By "useless" I meant useless to use linear algebra not useless in general
My bad I should have said it differently maybe wtv
You know diff eq?
We already talked about that
Not useful?
Maybe not for you but for lots of others
So its very possible its useless for you
Read all my texts
Ok
I think ill disagree on some points such as useless to use linear algebra
If you continue to explore math this perspective will easily change
So good luck and hope you learn what you like
maybe conflating the topics of "linear algebra" and "the portion of linear algebra you learned in an introductory course"
Is sheldon axler considered introductory book
That's what I read
Yeah?
My college teaches from gilbert strang but I read axler on my own
axler (as with any intro linalg book) is very much focused only on the linear algebra of finite dim spaces
What linear algebra algorithms or tools do you use in differential equations
linear algebra on inf dim spaces tends to be called functional analysis
Same ones you use in finite dimensional cases often
Need to theoretically make assumptions to use them though
Like
The goal is going from less tractable problems to more tractable
where do you use the fact that I can simply worry about finding nxm numbers instead of some transformation
The facts like these
That makes things simpler
Sorry not sure what you mean
All linear transformations from finite dimensional spaces is a matrix so if I want to find that transformation I just have to find that matrix
That's what I mean
Yeah
Depends
There are certain types of linear transformations that are the limit of finite dimensional ones
Are you considering infinite size matrix now
And facts like these are important in convergence for discretizing operators in diff eq
Also things like the radius of spectrum for finite dimensional operators and convergence of algorithms also carries over to infinite dimensions
So lots of the topics introduced have nice analogies
But isn't vast majority of tools in linear algebra only useful for finite dimensional spaces?
I wouldnāt say that
Finite dimensional linear algebra is well understood for the most part
Lots of questions we have can and have been answered already
Its also very common to model some things as finite dimensional even though they are not
Because it opens up so many tools from linear algebra
This is the main reason I thought like that
Yeah exactly
Well thats the thing, people in math try to make some of these models consistent , so in a limiting sense the finite dimensional approximations are correct
And we can have error bounds on how close we are to an answer
So we can agree that there is HUGE gap between the way finite dimensional spaces work and infinite dimensional spaces work
Yeah there is a big gap for the sheer amount of questions that come up and the different types of vector spaces you need to deal with
No longer do you have same dimensions being isomorphic
Makes things harder
A lot of the stuff we care about stays the same though
Like factorizations/decompositions, spectrum, etc
And the thing that brings that huge gap is having finite basis? So finite basis and infinite basis should be considered different thing?
I guess so?
But usually there is a lot more structure associated with infinite dimensional spaces
Well great that's exactly what I wanted to say
Like you consider the topology more often than in the finite dimensional cases
Ye
I mean if you find a use for caring about them thats great
But its very possible you donāt need to if you stop with math
And it would be an interesting choice to not consider learning about infinite dimensional things when they come up voluntarily, but it can be done
That's the thing right, they come up all the time but we still approximate them as finite dimensional
Because finite dimensional is so much "better"
Sometimes just depends on question you are answering
Like lots of linear function spaces we dont approximate when doing math
Is there anywhere you try to model finite dimensional as infinite dimensional because that would make it easier?
Yeah that I agree
Exactly
I dont know your point
The point is infinite dimensional and finite dimensional are very different things and work very different way giving them same name is kinda weird that's it
Like there are times we consider rational numbers as real numbers because we are curious what a finer solution space would look like?
Well they arent so different and so warrant that
And finite dimensional is more "useful"
That would be purposely confusing especially when lots of things carry over?
Yeah I think I'm biased because so far I only learnt from book that focus on finite dimensional
So yeah I should stop talking
Have you taken an analysis class yet?
Ok cool
Im doing ee
Engineering or something is cool too
Yeah if you ever do control theory or take a signals class
Youll be in diff eq world
I did take signals class
The linear algebra stuff comes back strong
Signals and systems
Yeah again most things in signals and systems we approximate as finite dimensional
FIR for example
Its an example of where we need to go from inf dim to fin dim
And consequences of that
I see
Sounds cooler
for uni interviews do you guys think using the cast diagram for questions might show a lack of trig understanding
which is what some guy doing a maths degree said
Has any non french here heard about the x-ens math exam
u can use the circle or the graph but i don't think anyone would care really
the people interviewing you already think you are missing a lot of understanding
it's just that cast diagrams don't work with special values
do any of you need a affordable editor?
yes
Well VS Code is free already so that's pretty affordable
like what kind of editor costs money lol
well visual studio
but all the other ones ik are either free or open source
i just use a good old open source text editor 
there are paid ones out there, but as with most paid software you only get it if your employer wants to pay for it
maybe they meant editor as in a person who edits
SublimeText used to be pretty popular
large datasets are not meant to be edited by hand
but if you need to, there are tools that access just the relevant parts, vscode is not that tool
A lot like sublime or most IDEs
Indeed, MS Excel is
But the vast majority of people should probably be using code or codium. With a smaller minority using a preconfigured neovim.
And the rest know what they want.
normative editor moment 
Hey I use helix. But letās be real
the vast majority of people use a popular paid IDE like jetbrains, or code/codium, or (neo)vim
iāve never heard of code/codium is thatās what the kids are up to these days?
vs code
vs codium is vs code compiled from source without Microsoftās added telemetry and such.
ah, so, yes then
how old is vs code again?
i remember when everyone was using netbeans
seems itās been the #1 most used editor since 2018 according to the stack overflow developed survey
i guess itās almost out of kindergarten then
Is there a preferred channel for math animations and such?
it's fine if you post them here or in #math-discussion
thanks.

hey guys Good morning to all
How large we talking
Pandas dataframes are kinda OP for editing large amounts of data
If you are doing stats then R also has nice dataframe structure
Actually it depends how big we talking
Over like 50 tb and you might want to work with databases
I just use vim it's the most I'm comfortable with
can somebody tell me the definition and of the dot product and the cross product , and thus how to solve 3 dimensional force diagrams
sublime is free tho?
at least used to be
iirc notepad++ handles large files fairly well
Jetbrains IDEs
Woah I'm surprised helix is popular enough to be mentioned here
50 TB is quite a lot even for Google BigQuery and similar.
I mean, it will process it, and quickly, but it will cost you
Also it hugely depends on what exactly it is you're doing with the data.
Simple aggregations? Transformations applied to individual rows? Window analytics?
Does your data even have "rows" or "columns" to speak of?
Outsider
I hardly...
hard?
Never mind, it was a feeble attempt even by my standards.
Relatedly, it reminded me of the fact that the highest throughput for data transfer still involves actual freight of storage media.
Latency is horrible of course, in this case.
huh, guess thats new. Shame, its a nice editor
isnt it basically free tho ? like they just prompt u when u open the thing, but nothing except that
Yes, but sometimes that doesn't matter; I think that's how data from astronomical observations in the Atacama used to be sent: https://cordis.europa.eu/article/id/32796-new-cable-makes-astronomical-data-easily-available
As the article says, they seem to have since laid a cable, but they used to literally ship the drives with the data because that was the fastest option
It's really hard to beat the bandwidth that physically shipping memory offers
Because it's [arbitrary amount of data]/[shipping time ~ 1 week?]
Yeah, and if you just need to get a large chunk of data, and don't need it immediately, then the "latency" isn't really an issue.
You don't query a new portion of data from the observatory every time, you get the drives, load it all into your local database, and query that
ayo, anybody here heard about the euler circle's independent research and writing program?
Yep, because it naturally selects for people who are clever enough to notice there's more than one discussion channel.

discussion-2 is slower and generally higher!
quality
but I find the speed and chaos in discussion to be nice too 
I think you've forgotten how much I lurk :p
I've genuinely gotten faster at reading by following discussion when there's 5+ convos going on at once
does anyone have a good integral that i can try
whether or not the things I've read are of quality... remains up for debate
hello! you can try asking this in #calculus 
sqrt tan
alternatively, there're lots of integrals on the internet you can find too
i bet u could transfinite induction
Integration by differentiation
The best kind
this one's cool
Oh, I think it's fairly clear

Guys when i'm in 10th grade should I take AP calc bc or just normal calc bc
It is a shame we don't call the complex exponential the complexponential
I'm glad we don't call stupid ideas stupideas

We should
It would be cooler if we did
Saw this and thought it was funny. Hope someone else does too.
For integer n>2, suppose the 2^(1/n) is a rational number.
By definition 2^(1/n) = a/b where a and b are positive integers
2 = (a^n)/(b^n)
2*b^n = a^n
b^n + b^n = a^n
By Fermat's Last Theorem no solution exists.
Therefore, 2^(1/n) where n is an integer > 2 is irrational
The proof of Fermat's Last Theorem is left as an exercise to the reader.
For some reason I have been having a special love for AP Human Geography.
Iāve never had a liking for history, and APHG was a history class, and so I immediately didnāt really like it since it was all about memory. But for some reason, Iāve been starting to enjoy it and suddenly the big scary amount of concepts in APHG feel so small and minimal.
APHG explains the āwhyā of history, and I love it so much. I suddenly am so interested and want to go into it more and use it. So many things could be applied to real life that are in APHG, and I have never been in a class where so many things look so applicable at this time. I love APHG ā¤ļø
That is so something my graduate school textbooks would have done...

lim x->ā¾ļø (-2)^x
+ā¾ļø Or - ā¾ļø
Neither.
It does not have a limit.
Can I have graphic about it?
ā¾ļø
It swings up and down, and up and down with increasing violence
You considered (-2)^1.5 real number?
Ah, we're considering real x, not just integer x?
Yeah, but now I think it is wrong
Did you make this graphic yourself?
Yuh
Well, if we're considering real x, either it's not defined for a lot of the values or x, or we're slipping into C
It'd still be divergent
But I forget if it'd be right to say the limit is infinity
How is that defined in the complex plane again?
Isn't it a little annoying how you can be living a normal life in the real line, you do one wrong operation and oops, you're in an entirely different plane of existence?
I think it must bother the reals how often that happens.
Yes

Guys, Grade 11 just started for me and a friend of mine knows calculus, matrices, sets, vectors and all other stuff but I feel like Trash next to him. I just started learning Trigonometric graphs and identities. I want to speedrun after bridge course in summer holidays and compete with him. There is too many concepts in Math and physics. After Trigonometry, what topics should I go order by order to become the goat. Should I learn sets and relations and functions first or logarithms first.
Pls someone explain
Like what
do you have a motivation to do this aside from "my friend being smarter than me gives me an inferiority complex"
hey wait i study this stuff
except i'm in gr12
i mainly do this because i have a goal of like getting through most of Calc III [which i'm pretty sure is super heavy info] before i become 18
goal + "i like it and it will most likely benefit me and make my life easier in the future for the fact that i'm probably going to revisit it again in university"
No its just that he kind of roasted me for not practicing extra stuff
like relations and functions, sets, logarithms, vectors etc
roasted in a malicious way or in an unambiguously friendly way?
No he kept on saying from last year to practice extra but I took no steps. So not malicious neither unambiously but like mid as if u keep studying like this u are going into a trash engineering college failing JEE mains
are you indian by any chance
oh you are
cool, anyways this shit does not matter lmfao
there''s no point in trynna learn stuff merely to compete w him
i guess the people here are mostly just warning you about trying to overachieve
there are several things to be careful about here
if you set your goals too high and fail you can be disappointed
secondly, yes its good to have a motivation to learn math but dont learn math for the sake of math only
That's why I am asking for a structured order to learn
you also want a well rounded education
sure, but the people here mostly just wanted to first check with you that you're aiming yourself in the right direction before sending you off
you get what i mean?
after trig, there are basically a few routes you can take
you can go discrete math, like combi, probability, stats, game theory
or you go the analysis route, limits, calculus, linear algebra, analysis
but there are plenty more
dont ignore like recreational math, puzzles and brainteasers
comp sci is another related route but still different because it goes into algorithms
probably tack on complex analysis somewhere in there
and remember to be well rounded, its good to have expertise but its more important to be well rounded
read humanities, make art, dont obsess too much on just math
youll rot your brain that way
I know I waste so much time on anime each day
So I have to focus on math and physics
anime isnt bad as long as its a proportionately reasonable amount of time
and also if it isnt all super low quality trash
that can make a difference in the long term
sorry I am wasting ur time
Thanks for the support
Really I mean it
Its just that the guys in my class are solving stuff like calculus while I am learning trig
I just got frustrated
that's all
understandable
Hello discordians, im new here
hey! I'm new too wassup?
im good, im here to learn math
lol me too
what math topic you're learning
ok, im learning algebra 1, and im stuck at decimals
Iām on that too lol
Mainly because Iām refreshing everything prior to calc because I want to jump into more complex stuff
And i wanna have my baseline set
When Lindemann proved that Ļ is transcendental in 1882 Kronecker said "Of what use is your beautiful investigation of Ļ. Why study such problems when irrational numbers do not exist."
pff
Kronecker would have been a joy in this discord
why is the delta named after hisself
@river orbit yeah im too stupid to understand being motivated and calm
i feel like they oppose each other
if i wanna do something im not calm
<@&268886789983436800>
what does that mean what else would be a good reason to
i wish it got better
when i catch up to my classmates, theyre already further ahead
buncha geeks man š
i typed this a bit quickly, i meant as in like there is more to math than just understanding the concepts, if you study math for the sake of math, make sure its because you have either an interest or a concrete goal in mind, like preparing for a career path
its not just about hard memorizing theorems and ideas
do u read lookism
Wait what
Oh u are saying the manhwa
I am going to read it soon
oh nvm then
i remember a weirdo called gojo satorou in a lookism server
i thought it probably isnt you
but then i saw youre Indian and who knows
not worth it
it gets so bad
the authors just milking it
he doesn't even know himself why the main character gets two bodies
Oh
So its not a good manhwa
well for a time it was my favourite mamhwa i guess
so perhaps its worth reading (but its also a waste of time to go through 500+ chapters instead of studying)
but i ended up dropping after 520 chapters cuz it got too bullshit
one man fought against hundreds of men, the strongest gen 2 fighters, his supposed equal and went on to defeat the perfect body while being in a weakened state
all because he has black bones
his neck was even deeply cut by a sword
but its manhwa so thats a minor injury who tf has arteries
it was good until around ch420 i think
Is this actually true?
i have it from st andrews university pages on math history topics theyāre good sources
Kronecker was a constructivist
also wb
Typical algebraist behaviour
Deltoid: i hate algebraists
Also Deltoid: working with lie algebras

Another feature of Kronecker's personality was that he tended to fall out personally with those whom he disagreed with mathematically. Of course, given his belief that only finitely constructible mathematical objects existed, he was completely opposed to Cantor's developing ideas in set theory. Not only Dedekind, Heine and Cantor's mathematics was unacceptable to this way of thinking, and Weierstrass also came to feel that Kronecker was trying to convince the next generation of mathematicians that Weierstrass's work on analysis was of no value.
We should not think that Kronecker's views of mathematics were totally eccentric. Although it was true that most mathematicians of his day would not agree with those views, and indeed most mathematicians today would not agree with them, they were not put aside. Kronecker's ideas were further developed by PoincarƩ and Brouwer, who placed particular emphasis upon intuition. Intuitionism stresses that mathematics has priority over logic, the objects of mathematics are constructed and operated upon in the mind by the mathematician, and it is impossible to define the properties of mathematical objects simply by establishing a number of axioms.
there seems to have been a particularily bitter dispute between cantor ans kronecker
i think this is likely one of those things thatāre overly sensationalized in pop math history
i donāt think one should draw the most accessible conclusions from what limited information we have on these kinds of topics
i donāt think occams razor applies to human psyche
Guys do we need to know real analysis to prove cauchy sequence is convergent
Or is there some short proof for understanding on surface
i am not disputing this
Hi not sure if this is the right chat to ask but I was just curious as an early university student doing maths I'm currently at a choice whether to choose statistics or pure maths/mathematical physics and was wondering if anyone had any insight where these two different options could take you
Pure is awesomer
Very real
Everyone give me dare!

Prove or disprove this: https://en.wikipedia.org/wiki/Collatz_conjecture
The Collatz conjecture is one of the most famous unsolved problems in mathematics. The conjecture asks whether repeating two simple arithmetic operations will eventually transform every positive integer into 1. It concerns sequences of integers in which each term is obtained from the previous term as follows: if a term is even, the next term is ...
Easy
It's true
But the proof is too long to fit on Discord
Nah bruh just look at the histogram it obviously decays fast enough
Dunno how to prove it though
mathematicians when their proof by computer proof search is petabytes long 
ā¤ļø
It just be like that :3
Dare acceptted
But the conclusion is unequivocally that 0.9999.... isn't equal to 1
, but it is?! Isnāt it?!
Well, that's what they would like you to think
Pardon?
I'm being facetious.
In the decimal notation as it is understood by most of us; 0.9999..... and 1 do indeed denote the same real number (said number being the multiplicative identity in the field of reals).
what?!!?!??
idt that has anythibg to do with computer proof search
I was being facetious
The joke being "petabytes of data for a proof of something false"
right
now i wonder if proof search ever has whipped up anythibg false, because iād imagine not
false of course meaning within the system the computer is working with
itās interesting to me that there are quite impressive computer-aided formal methods like automated theorem proving, but as i understand it general search afaik has not really yielded any particularily interesting new results; the famous computer proofs like that of the four colour theorem were done by programs that were highly specialized for that problem
It's a powerful theory though

I think someone once posted here a kind of survey where the questions were algebra vs analysis and straight vs queer

see also avigad's more recent essay on AI's implications for mathematics https://arxiv.org/abs/2502.14874
Generally, when we ask ChatGPT a question, we care about the answer. Whenever we turn to AI for advice, we should question the wisdom of putting our lives and livelihoods in the hands of a system we donāt understand. We should worry about whether the information we get is reliable, aligned with our interests, and likely to help us achieve our goals. We should worry about our safety and security, and since our decisions affect others, we should worry about whether the advice we get reflects our values and morals. For these reasons, we want AI to be transparent. We want AI to tell us not just what to do but also why; we want reasons, explanations, and justification. We expect no less from doctors, lawyers, salespeople, financial managers, and contractors, and we ought to expect the same from AI.
(spoiler alert: no!)
but nor can we naively ignore ai
Now, with the advent of AI, there are two paths we can follow. The first involves carrying out scientific reasoning and decision-making the way we have since Galileo but using AI to do it better, improving our mathematical models and obtaining a deeper understanding of their properties. The second involves bypassing mathematics, leaving AI to draw conclusions as it sees fit, and accepting its oracular conclusions. The first path opens up exciting opportunities for mathematics and science, because AI offers us new means to discover and understand phenomena that would otherwise remain opaque to us, to think and reason better, and to make better decisions. If we go down the second path, it will mean turning our back on science, relinquishing agency over our practical decisions, and giving up a vital part of what it means to be human. AI offers us the choice, but it does not tell us which path to take. Itās up to us to get it right.
good essay, thank you for sharing
Nice essay. Thank you for sharing
I hate doctors
What does āoracular decisionsā mean?
why donāt you see if you can figure it out yourself
I tried
Itās not at all clear
do you know what an oracle is
No
Yes, but they are restricted by potential competition
If they act against the interests of the consumers, a new business will arise and outcompete them
So they are restricted to act in our own interests
so is this good or bad in your eyes?
sup my skibidis
i think that sounds fine to an extent
i would argue that as long as a business acts in favor of their shareholders, and assuming the shareholders in question do not respresent the consumer, then that business has the potential to outperform other businesses that in fact do act in interest of the consumer
Itās good
People want to earn money, due to the positive value theory they canāt do it unless they give something back
i agree, people should put in to get something out
if they can that is
Shareholders want to earn money to. If they see that a business is failing due to consumers not wanting it they will sell immediately to avoid losing money
okay sure, not sure where we're going with this actually, i dont think either of us have made a point yet š
