[native cove]

Well I've never received recognition, I thought maybe being blunt would help people get it.

[latent edge]

https://tenor.com/view/whatldoo-whatldo-gif-21848551

[solar hawk]

Get what

[solar hawk]

Yay!

[fresh comet]

you can always talk to people on this server about math if you'd like

I find this place to be quite helpful

[latent edge]

Yeah you can learn analytic number theory for example

[fresh comet]

try not to come off as boastful though

[fresh comet]

real

[solar hawk]

Unless you accidentally become amukh 2.0

I think I have a chance to escape rn

[neat lintel]

Based

I need to change my nickname

I can't tho

[latent edge]

"skill issue"

[neat lintel]

ouch

[solar hawk]

Deltoid

How do I become like you

[neat lintel]

aint no way vro i got 4.0 gpa in high school I'm so proud nglngl frfr skull emoji

[latent edge]

wdym like me

[fresh comet]

you'll give me brain damage if you do this any longer

[solar hawk]

How did you do all that

[solid snow]

The most productive thing will probably be to get over the “nobody understands me” mindset because you decided to study undergrad math

[native cove]

@neat lintel you could be trapezius

[solar hawk]

I thought math was a popular topic

[solid snow]

Not really

[neat lintel]

excuse me wtf

[fresh comet]

not at all where I came from

[solar hawk]

Math or cs Ig idk

[fresh comet]

even now, there are probably twice as many physics students as math students here

[solar hawk]

What about the schools

Ohh

Well I mean that’s diff

[latent edge]

Idk I'm naturally just very bored so I just tend to do it anyway

[ripe needle]

This. I don't have a single person IRL that likes math or has even taken math courses after HS. I socialize just fine.

[latent edge]

If you mean studying what I did in HS

[solar hawk]

Iv found plenty

[latent edge]

I wouldn't recommend it if all what you care about is prestige and shit and getting into Ivy league or allat crap

[solar hawk]

But I can still somewhat socialize with everyone I think

[neat lintel]

I wanna be like deltoid fr

[native cove]

Unrelateable

[solid snow]

Even if you do find someone to talk about math to, its a pretty dogshit conversation topic unless both of you are working on something / similar field of study.

[ripe needle]

Ffs

[solar hawk]

I mean how did you stick with all those things

And they didn’t even sound like the same thing

Y didn’t give up in the middle

Wait Hgr I hope I don’t give up on you

[latent edge]

depends on what you mean by giving up

in what context

[solar hawk]

Like dropping something

[fresh comet]

tbh I'm also a bit worried about losing motivation

[solar hawk]

I never complete stuff ;-;

[fresh comet]

that's why I think that if you read with me it'll be easier for both me and you

[solar hawk]

To keep eachother at it ig

That reminds of

[native cove]

If you lost motivation watch those little dark age math edits on yt

[solar hawk]

Me of a game

I used to play on Roblox

[solar hawk]

Bruh 💀

[fresh comet]

yeah to keep each other accountable so to speak

[solar hawk]

I gotta get back on Roblox tbh

I paid a dollar

[river moon]

I made one little dark age edit and it gained 9000 views and youtube banned it

[solar hawk]

For some robux and I bought 1 months worth of something with it

So I suojld@play to get my worth’s out

[native cove]

Roblox is literally for 4 year Olds and 54 year olds

[solar hawk]

Bro

[latent edge]

oh

[solar hawk]

Lots of adults play Roblox

[latent edge]

Well you gotta stick up with it when it gets tedious

[solar hawk]

It’s never boring it’s just

The problems take fucking forever 😭😭😭😭😭😭😭😭🤬🤬🤬🤬🤬

WHY

Progressively harder

[native cove]

To whom it may concern, I have come to the understanding that the term "bro" is a meaningless abbreviation of the term "brother" that is only used to call attention to someone's action or behavior (the implication that it was foolish or deemed unacceptable by his or her peers).

[fresh comet]

yeah that's how it is

[fresh comet]

is this a copy pasta?

[solar hawk]

I understand why you don’t have friends

[latent edge]

oh

well

I recommend a crash course in sieve methods

[solar hawk]

Sieve?

Is that a study method

Or is that roots of polynomials

[latent edge]

yes

[solar hawk]

Oh

Wait

[latent edge]

study method for something

[solar hawk]

Ok

[fresh comet]

here comes the propaganda

I'm all for it

get amukh into AnaNT

[ripe needle]

It gets worse.

[solar hawk]

Bro this stuff is number theory 💀💀I suck st numbers

[latent edge]

you gotta realize the problems will get harder over time

[latent edge]

sully

get good

[solar hawk]

I’m not allowed

Dami told me

[latent edge]

wtf

[solar hawk]

To finish Rudin or Abbott

[ripe needle]

You've been counting since you were like 3 wdym

[solar hawk]

Legally binding contract

[solar hawk]

Shit I forgot

!!

Dw deltoid

Ima hit you up when I’m finished abbying

[latent edge]

Yeah maybe do a bit of Rudin

You don't need all of it for sieves

[solar hawk]

Yea but I need all of it before move onto next subject

[latent edge]

like idk lebesgue theory is a must

[solar hawk]

Otherwise I will be stoned by the animals in my room

Ok not lebesuqw

Just Riemann

[ripe needle]

Rudin's RCA

[solar hawk]

And stop there

[solar hawk]

No

[latent edge]

at least do lebesgue dominated convergence theorem

[solar hawk]

I’m DONE with Rudin

[solar hawk]

O _ O

I’m- I’m still in chapter 3

[latent edge]

u need a motivator fr

[solar hawk]

My motivator was spivvy 😭 but I got too motivated

And I can’t wait until finish Rudin

And apparently spivvy is and

Bad

But it’s ok nobody will know

[fresh comet]

that's why amukh should join me in learning topology fr

[ripe needle]

Which text

[fresh comet]

ITM

Introduction to Topological Manifolds

[latent edge]

I think my breaking point in math was Hartshorne and sieve methods

Hartshorne's AG is bleak

I mean I did have real struggles in analysis but Hartshorne is different

[sonic sentinel]

can animals "forget to take their stuff" like humans sometimes do

like literally any object

im guessing they can't cause the number of objects they use and situations to use them in are small enough that practice and biology makes it easy to remember

[river moon]

there are birds that store mouse and lizard corpses on tree branches and then forget to eat them

and squirrels that bury nuts and then also never dig them up again

[neat lintel]

what if humans bury great ideas and then also never dig them up again

[river moon]

that's poor planning

[neat lintel]

yea pencil and paper kinda helped with that one

[icy void]

Where can i read basic mathematics by lang for free

[solid snow]

dont spam your question in every channel

this was also answered hours ago

[surreal bison]

The Bull-Leaping Fresco is the most completely restored of several stucco panels originally sited on the upper-story portion of the east wall of the Minoan palace at Knossos in Crete.

Year: 1450 BC

Yes, that's right, Frescos have been around for that long

The Minoan civilization developed from the local Neolithic culture around 3100 BC, with complex urban settlements beginning around 2000 BC. After c. 1450 BC, they came under the cultural and perhaps political domination of the mainland Mycenaean Greeks, forming a hybrid culture which lasted until around 1100 BC.

@keen sinew I always had some interest in history, and not being in highschool had increased that

[keen sinew]

ah i see

[surreal bison]

...you are very cool now, interesting.

[keen sinew]

haha i wanted to give to the server

[keen sinew]

im tryna run something by namington so i can gift something to someone who wants it but he hasnt responded to my DM

thats just the mod i picked to dm

i didnt know who to pick

[surreal bison]

you're giving things? i'll take things

[keen sinew]

idk yet

[shadow aspen]

The entire English language can be summarised to “Sphinx of black quartz, judge my vow”

[next schooner]

what is the gift. I want it

[surreal bison]

and all of mathematics can be summarized to "{,}, ∈, nand", and an infinite set of distinct letters

[keen sinew]

idk if i can yet

[next schooner]

im a mod.. i deserve gifts

[surreal bison]

you see the problem?

[keen sinew]

oh i need some sort of proof

[shadow aspen]

Ha ha! What about i

[surreal bison]

what

my point is that a set of letters does not contain all the data about a language

[next schooner]

Going via modmail is the best bet

[surreal bison]

for a formal language you need rules like rewriting rules

[surreal bison]

what's the issue

[next schooner]

Yoo is it generative grammar hours

[surreal bison]

really you should say "what abotu "="" which i forgot

[shadow aspen]

A person looking at bianary would say it’s summerized in 1s and 0s

[next schooner]

Good job globe chomsky is Here

[surreal bison]

you do need logical equaliry

[surreal bison]

1 and 0 are already covered by "{,}"

just construct the natural numbers the usual way

[neat lintel]

What’s your point here?

[surreal bison]

but a set of letters doesn't suffice to describe a formal language

[next schooner]

grammar

You need a fuckin GRAMMAR mate

[solid snow]

yyou actuallyy dont

[shadow aspen]

My point being everything comes from parts, and we can think of rules to create these parts, but no matter what, it all comes back to the parts

[solid snow]

only if your language is a code

xD

[shadow aspen]

Grammer isn’t something you have, it’s a quality

[solid snow]

otherwise there exists nonunique factorizations of your word over the alphabet

and so you can't treat them as fundamental "parts"

[shadow aspen]

How do you know our language isn’t code. Code has grammar

[solid snow]

im using code in the mathematical sense

from language theory

[surreal bison]

unhelpful. chomsky is correct here

[surreal bison]

i'm not sure what you mean, do elaborate

[solid snow]

a code is a language without the empty word that has unique factorizations over the alphabet

[shadow aspen]

Anyway, I’ve dug myself into a hole over a joke. I must abduct myself from this hole like the green goober I am. Remember, the numbers don’t mean anything Mason

[solid snow]

i.e $X \subseteq \Sigma^+$ is a code iff. $ w = x_1,..,x_n =x_1',..,x'_m \implies m = n$ and $x_i = x_i'$

well each x_i = x_i'

[fathom swallow]

josemom2

[solid snow]

\Sigma is an alphabet and \Sigma^+ is its kleene closure without the empty word

[neat lintel]

I have the slight suspicion we are getting into theory of computation here.

[solid snow]

yes

[neat lintel]

I'm gonna start reading introduction to the theory of computation this weekend. Call me in a year and i'll be able to not talk about it still

[proven knoll]

This question reminds me of someone named Jim Simons

[dire glen]

trying to understand a bit better what does it means for 2 functions to be lin independent. I know what it means for vectors

the functions 5 and cos(x) are linearly independent.
but i can take x=0 and multiply cos(x)by 5 and I would get 5

why am i not allowed to do that?

[neat lintel]

No, you're bound to be poor to eternity

[vivid halo]

This is analogous to saying “the vectors (1,0) and (2,1) are linearly independent, but I can take the first coordinate and multiply 1 by 2 and I would get 2”

The value of a function at each x is a different coordinate of a vector in an infinite dimensional vector space

[dire glen]

ok i need to consider all the values of the function

gotcha

also, i've just realized the dot product for 2 functions as a parallel for fectors

it's same thing but vectors have a discrete amount of values

and functions are continuous

so i'm taking theintegral and multiplying them

[old oak]

Yep, it's essentially the same thing, as nGrupoid pointed out, function spaces are infinitely-dimensional vector spaces.

So they're still vector spaces and a lot of things carry over very nicely from the finite dimensional case

And some things get much gnarlier

[dire glen]

and this dot product idea is great because i can look at it also frmo the perspective of "how much a function is similar to the other?" and if you think about it you can say the exact same thing when you take the dot between 2 vectors.

[old oak]

Yes! Very good observation.

[dire glen]

i feel with linear algebra now i'm connecting many pieces together

[jagged forge]

linear algebra is pretty OP

[dire glen]

many a-ha moments

OP?

[jagged forge]

overpowered

my first a-ha moment was realizing i could use linear algebra to solve linear differential equations

well, only very simple ones. but still it was cool, and i hadn't taken DE's

(still haven't actually)

[dire glen]

i'm doing them now, and stoing fourier series. so i've started learning about them and found some videos that explain the relation between fourier and linear algebra

i feel i'm on the upper floor now and i can see everything from a bit higher up

so in the case of functions, it's called inner product right?

[jagged forge]

well, in the finite dimensional case it's also called inner product

it's just a generalization of the dot product, i suppose

[dire glen]

but you cannot call dot product for functions?

[jagged forge]

no i haven't seen the term used that way

or rather, no one writes $f\cdot g$

[fathom swallow]

suremark MSC2020 60G40

[jagged forge]

except when they mean plain multiplication i guess

[old oak]

In infinite-dimensional case you typically write <f,g> for the inner product.

But the fundamental mechanisms are the same

[jagged forge]

or E[XY] :^)

sorry ill show myself out

[glass peak]

You also get lots of inner products that don’t look as much like the dot product

[old oak]

Probably because dot can be confused with pointwise multiplication, and circle with composition.

[old oak]

Also that

[jagged forge]

yeah that makes sense

[dire glen]

cool

🙂 thank you!

[neat lintel]

What does not looking like the dot product mean?

Every hilbert space of same dimension is isomorphic so id say every inner product looks the same

[glass peak]

That is actually a fair point, but I was getting at the fact that inner products don’t need to be just term wise multiplication and addition, or the obvious generalisation to the integral but yeah I get that point

But I was mostly just trying to make it clear to someone learning this for the first time that you can think much more generally than the dot product

[raven plaza]

Another way to think about this is that every inner product is the dot product under an appropriate choice of coordinates

[dire glen]

i don't know what this means. what makes a dot product more specific than inner prod?

[solid snow]

a dot product is a specific case of an inner product

[glass peak]

An inner product more generally is just a symmetric, positive definite bilinear form, so more than the dot product can satisfy that

[raven plaza]

If you have coordinates x, y, z, then you can define a dot product (a, b, c) · (d, e, f) = ad + be + cf

But notice this depends on your choice of coordinates x, y, z

For any inner product, you can choose coordinates so that the inner product is the same as the dot product you get from the coordinates in the above manner

[dire glen]

i could continue asking questions on this but i think it's more advanced than what i know now

i'm still not sure what you mean

maybe i would need an example

is "the same"?

[glass peak]

Consider Tr(AB^T) where A and B are both square matrices, that’s an inner product. I think it’s quite easy to see how that looks similar but not exactly like the standard dot product

and of course you can always just change basis appropriately to recover the dot product

[dire glen]

i don't know what you've written sorry.

i'll study this one day

dont worry too much

thanks for trying 🙂

i only kno ^T is transpose

but Tr i dont kno

[rocky shuttle]

it's the trace of a matrix (sum of its diagonal entries)

[dire glen]

unrelated question but kinda related

did fourier knew about the linear algebra approach to its series?

was it already a thing?

did he get there through some other intuition?

[tacit magnet]

Due the solutions of wave equation

In 1 dimension

The solutions are u_k(x,t)=(A_kcos(kt)+B_ksin(kt))sin(kx) with k an integer (the k appear due boundary conditions)

So the sum of all solutions is also a solution of the wave equation too?

That was Fourier idea

At least what they told me the first day at harmonic course

[glass peak]

That was also how I was taught it in my waves course

[tacit magnet]

[proud olive]

Actually only way to calculate the trace of a matrix is to find its eigenvalues and then add them together

That's the only way

[deep mango]

Compute log(det(e^A))

To compute the determinant, pick points at random from a gaussian and compute the proportion whose preimages under A land in the unit cube

And transform it correctly

[proud olive]

Monte Carlo is for bussys

Ok I honestly got no clue why this gives the correct answer

[deep mango]

It doesnt, you need to do some weighting

[proud olive]

Am I just going to use a finite series of e^A?

[deep mango]

Oh for the log of det e^A

Thats hard to prove

It comes from jacobis identity

For d/dt det(A(t))

Which is like

Something dumb like tr(adj(A) dA/dt)

[proud olive]

What in the world is adj(A)?

[deep mango]

And you apply that to e^tA to get a diff eq

[proud olive]

Adjoint?

[deep mango]

Classical adjoint yeah. The one with the cofactor determinants

Or "adjugate"

It's something like det(A)A^-1

[deep mango]

To show this you can just compoot i think

[river moon]

the collection of derivatives of determinant function

[rocky shuttle]

Jacobi's formula

[proud olive]

Yeah this is not going to be easy for me to compute. I need to find some closed form of the determinant and that's going to take some time

[rocky shuttle]

You only need the multilinear property of the determinant and the cofactor expansion

[proud olive]

Oh, ig this involves some induction stuff then?

[open mauve]

Hey guys how do i learn units I have never seen before on dimensional analysis khan's video on algebra unit 3

for some reason now when i think about playing it now there's some weird anxiety in the background of fearing failure

hopefully about to play bedwars solo for the first time in years, wish me luck

[neat lintel]

Guys need advices for a beginner in Maths and going to the second year of HighSchool I'm bad at Math and I really need your help or a roadmap that you would advise yourself if you are in my place !

I've a passion on math about this subject

[calm vessel]

What's going wrong?

if you have calculus at school you can watch this series

https://www.youtube.com/watch?v=WUvTyaaNkzM&list=PL0-GT3co4r2wlh6UHTUeQsrf3mlS2lk6x

it really helped me

[neat lintel]

It is helpful for beginners to watch some vids to understand how calc essentially works
But to further advance in calc one must remember a simple way to convert math problems to calc formulas directly

[native cove]

de^x/dx= xe^(x-1)

[granite hound]

(d/dx)x^x = x*x^(x-1) = x^x

[neat flare]

I know this is dumb but what symbol substitute as the divide symbol? my sci cal divided button is broken

[neat lintel]

a/b = a*(b^(-1))

[glacial panther]

blasphemy

power rule only works when the base of the exponent is a variable and not constant

you can get the derivative for e^x by impliclity differentiating

y=e^x

ln(y)=x

y'/y=1

y'=y

y'=e^x

the derivative for a^x where a is a constant is ln(a)a^x

the derivative of log_a(x) is 1/(xln(a))

the derivative of ln(x) is 1/x

[spring falcon]

You can also do F(x,y)=y-e^x and dy/dx=-F_x /F_y

[glacial panther]

is that multivariable?

i haven't seen that notation yet

[spring falcon]

Yes

F_x is the partial wrt x

It makes implicit differentiation much easier

Comes from the chain rule for multivariable functions

[fading moon]

😂 it's not important lol

[severe lodge]

anybody here is familiar with the book "secrets of mental math: the mathemagician's guide..."?

[severe lodge]

would someone recommend me that book? i struggle with mental calculations

[cunning plaza]

I think you get better with mental calculations if you just do more math. That book is for "math tricks", but you'll learn various tricks if you just study more math. It seems like a fun book though.

Hmm I'll check it out. I'm curious.

[severe lodge]

eh, i disagree. i've done plenty of math thus far and i haven't really learnt to do math better.

"study smarter, not harder"

i'm picking up that book because i'm struggling, silly :p
(no offense)

[cunning plaza]

Actually it seems like a cool book

Maybe I'll read it one day.

Sorry for the earlier bad advice.

[scarlet lark]

wait we need to do mental calculation in math.

💀

I thought that was the job of the computer.

[neat lintel]

yeah

sometimes its faster than using the computer

[scarlet lark]

Of course.

[glass peak]

It is in my books, I’m not working out eigenvectors by hand if I can help it

[scarlet lark]

"sometimes"

As an exercise, you might as well make a program to do it for you.

[neat lintel]

i do that all the time

for stuff i don't want to do in my head

if you can do it in your head/on paper faster than it takes to pull up a program and enter in the values and have it calculate, then do it!

[scarlet lark]

(I hope everyone does that. We're not in the era where we need to spend hours to find an approximation of the square root of 2)

[neat lintel]

yeah

[cunning plaza]

This sort of stuff wouldn't help much with higher level math, but hey, being able to do simple arithmetic in your head quickly is nice.

(And yes I will use a computer.)

[neat lintel]

yeah, i can do stuff like 3 digit number x 3 digit number in my head

and simple integrals, is that normal?

[scarlet lark]

Of course.

[cunning plaza]

I think if you keep doing math then some things just become easy, so yes.

[neat lintel]

well........

[glass peak]

Quick mental maths is also very much a skill

[neat lintel]

thats the thing i dont have a lot of practice with integrals

[scarlet lark]

If you do them a lot, at some point you will be seeing integrals on someone's face. 💀

[glass peak]

I could do a lot in my head very quickly in highschool, but I can’t do shit without some paper now

And my ability to add and subtract numbers is probably worse than a lot of 10 year olds

[cunning plaza]

If you keep doing math you will get more practice.

[glass peak]

Because I just don’t do it very often anymore

[scarlet lark]

💀 mf just born different

I miss the integrals phase.

I might as well just do them during my breaks at this point. 💀 But the reason why I liked them was because they were not difficult to not solve and too easy to get them right away (sometimes).

[cunning plaza]

You mean Calculus 2? I don't. That stuff is way less interesting.

[scarlet lark]

Hey man I loved the flow.

But now I have to look at my whiteboard and go "hmmmmm, maybe, nah"

[cunning plaza]

I guess computing 20-some integrals and being done can feel good.

For a moment.

[scarlet lark]

Very much.

For a moment is very true.

I did one the other day and was not that impressed after an hour.

💀

But I would like to get my hands on (and have the time) to go through (Almost) Impossible integrals.

[neat lintel]

i ask chatgpt to do math problems, but i tell it to write code to solve it

alright i got one for you

wait lemme get the piece of paper

so basically

[scarlet lark]

🤔

[neat lintel]

its an acceleration function defined in terms of the exponential of the corresponding height function

[scarlet lark]

I'm already lost. 💀

[neat lintel]

so basically

[scarlet lark]

I'm joking.

Wait, what is a Height Function?

[neat lintel]

so basically f(x) is defined in terms of ∫ f(x) and e^((∫∫ f(x))/c)

[scarlet lark]

🤔

[neat lintel]

i need to find the second integral of f(x)

this seems nearly impossible if not impossible

[scarlet lark]

Wait you want to find a function such that $f(x) = \int f(x)dx$

[neat lintel]

my plan was to solve it through lots of computation for the thing i need it for

[fathom swallow]

NotRealJohnny

[neat lintel]

no

its DEFINED in terms of the integrals

but its not equal to integrals

wait lemme get the piece of paper

[scarlet lark]

:whaa

Get the paper please!

Get paper towel if you need to.

[neat lintel]

good luck

ima transcribe it now

,rotate

[neat lintel]

oh yeah, ph(T) = p_0 * e^(height(T)/H_n)

all stuff except for T is constant

accel(T) = (0 if T >= B_T else (m_f - m_0)/B_T(B_isp - ph(T)/C_isp)) - GM_B(m_0 + T(m_f - m_0))/(R_B + height(T))^2 - 1/2*ph(T)*velocity(T)^2*AC_d

velocity(T) = ∫ accel(T) dT

height(T) = ∫∫ accel(T) dT

problem is to find formula for height(T)

@scarlet lark here's your almost impossible integral

[scarlet lark]

hold on I gotta go bald real quick.

[neat lintel]

lol

"go bald" and "real quick"

[scarlet lark]

Alright, I am (almost) bald.

[neat lintel]

what did you find?

[icy void]

Why should i not major in math

[visual breach]

Why should you

[broken trail]

is anyone good with linear equations?

[craggy gust]

its hard and stressful

[neat lintel]

what do you think is the most stimulating activity in mathematics you have experienced?
(whatever action , from solving problems to learning new things ,
(in any context you want))
(by stimulating I mean addictive/exciting/motivating ,whatever is understood by something that generates strong emotions)

(or what you think in general is the most stimulating activity in mathematics?)

[craggy gust]

most recently it was proving there is a rational number between any two distinct positive real numbers

just felt counter intuitive because there are more reals than rationals

so it was cool it works out

[neat lintel]

how does it felt?

(I mean , in a more descriptive way)

how a ranking on this would be?

[fervent pebble]

solving problems after working on them feels like a little high

[neat lintel]

yeah , you think there is something more stimulating?

I am trying to check what is the more stimulating part of mathematics

[fervent pebble]

maybe some people really like rigor

idk

i cant think of anything that could be more stimulating than solving a problem

in math, i mean

[fathom swallow]

Serphic

[fervent pebble]

im not going to check if that's correct but if it is it's well known

is it useful?

there's probably some cute identities you can have with this

@sturdy gulch

depends on if u consider that useful or not

[sturdy gulch]

i was thinking of if there's a way to write a number to an exponent in terms of a number to a smaller exponent and then solve for zeroes or something

[fervent pebble]

i think you should look up the connection between the fibonacci numbers and the golden ratio

[sturdy gulch]

no i do already know that that's how i got all of those identities

[fervent pebble]

wdym by useful then 😭

[sturdy gulch]

idk im just trying to apply it to something else 😭 i was just bored and was praying that i was finding something new (which i know for fact has almost definitely been discovered im just coping bc i didnt see it anywhere else)

[fervent pebble]

ah

not to pop ur bubble

oh okay ur aware

having said this

this is good!

playing around on ur own, figuring out (to you) new things

it's wonderful practice

[sturdy gulch]

like i was messing around and accidentally somehow found binomial theorem and was shitting myself until i found out im approximately 2000 years late 😭

[fervent pebble]

so there's not much to say for usefulness or wtv

but i am proud of you

and you should be proud of urself

[sturdy gulch]

welp time to move on to another thing to mess around with then!!

[fervent pebble]

gl!

[vivid halo]

I think the most powerful experience I've had with mathematics was finally solving a conjecture I was working on for about 4+ years at that point

checking my answers against the computer program the original authors used to formulate them (which I didn't have access to until the end) and seeing everything match up perfectly

that was really great

[sturdy gulch]

i'm almost certain i wont be able to understand it, but what was it?

[vivid halo]

a very detailed and explicit computation with the cohomology of Shimura varieties

the answer in the case I studied is like 2+ pages long lmao

[sturdy gulch]

yep that means nothing to me 😭 sounds cool tho

wait

i might've actually seen that before

[vivid halo]

the content of the computer program might be a ltitle easier to understand

you can sort of guess what the answer should be if you do very careful computations of like

[sturdy gulch]

YEAH i've seen hte langlands program

[vivid halo]

you count points on genus 2 curves (so curves of the form y^2=f(x) for f(x) degree 6 with no repeated zeros) over finite fields

the answer of the cohomology computation encodes a bunch of information about point counts over finite fields like this

[sturdy gulch]

that's starting to make a bit more sense but
i have not taken homology/ all of lin algebra yet for any of that to make full sense

wait
fields can be finite????
i am so cooked i did not know that 😭

[vivid halo]

yeah

I mean the standard example is integers mod p (Z/pZ)

that is a finite field with p elements, for p prime

in general you have a unique (up to isomorphism) finite field with p^n elements for every prime power, and that's all of them

they aren't just integers mod p^n in general, it's a little more complicated than that

[sturdy gulch]

aaand now im lost again why is it prime numbers 😭
yknow what i should probably just learn cohomology or smth
actually i cant

arent there like

3 years of pre reqs

[vivid halo]

prime numbers are relevant because like

you don't want things like zero divisors if you want a field

like integers mod n when n is composite are bad

for example with integers mod 6 you could take the nonzero elements 2 and 3, multiply them together and get 6, which is 0 in this ring

you shoud never be able to multiply two nonzero elements to get zero in a field

[sturdy gulch]

okay that actually makes a lot of sense

[vivid halo]

same issue obstructs integers mod p^n being a model for the finite field with p^n elements

anyways once you have finite fields you can do algebraic geometry over them, and there is a lot of stuff you can deduce from basic problems around like, take some system of polynomial equations over a finite field, counting the number of solutions over finite fields

the nice thing is a computer can do this and it's very easy to just do this by brute force (although maybe harder to do this in a smarter efficient way)

[sturdy gulch]

well that's fucked
the only code i know is 'hello world' and how to bring a calendar library or sum into python 😭

[vivid halo]

it's as simple as just like

let's say you just do this for integers mod p, so that's very easy to implement

if you had a system of polynomial equations in n variables over Z/pZ you would just like

idk literally just try all p^n combinations of inputs lol

[sturdy gulch]

see this kind of stuff is why i kinda wanna do pure math but like
too much math

like it's so exhiliriating when i finally understand the thing and can actually solve it and use it and whatever
but the 9 hours of bashing my head into the wall trying to understand how/why for every single topic is going to make me go insane

[merry plank]

Z/pZ so cute/strong and heckinbased

[merry plank]

Do it

[sturdy gulch]

thing is i want to have an applied use for math because
engineering sounds very fun and i want a job that i'll enjoy
could do pure math as like.. a minor or hobby or sum

fr now tho i could actually just get on the way there

[ripe needle]

Don't let Big Math fool you. This is common. There's many applied people.

[sturdy gulch]

big math 😭
no but fr it'd be very cool if i could actually find a use for some pure math in an applied job like

wasn't there something about prime numbers or sum that ended up being used in cryptography

[ripe needle]

There's whole areas of math being used in cryptography

[ripe needle]

https://en.wikipedia.org/wiki/Elliptic-curve_cryptography

[obsidian ingot]

by chance
can some1 please tell me whats wrong with my code?

[dire glen]

"odd and even functions. Most functions are neither of course."
why ?

i tought odd meant not even.

[mortal vortex]

I could be wrong but this is the answer that came to my head just now
When thinking about numbers, yeah theyre either even or odd
But functions are different, the definition for an even or odd function is completely different to an even or odd #

[vivid halo]

No

A function f is even if f(-x)=f(x) and odd if f(-x)=-f(x)

Typically neither of these properties is true

[dire glen]

ahh

so the fourier transform of a function that is neither, will have both sin and cos right?

[raven plaza]

Yea

[north topaz]

Mhm

[lapis ingot]

In AP exam, should I do Calc AB or Calc BC exam?

I haven't done research on many universities so I'm not sure about the majority of universities. From what I read from a few uni, Calc BC is often equivalent to higher courses.

But my friend told me Calc AB is for natural science and Calc BC is for data scientists, statisticians. So I should do Calc AB if I want to pursue professions relating to engineering or computer science.

Can someone help me to decide on a course to study, in case I can't do both?

[radiant remnant]

BC

BC is simply just better

it’s a superset of AB, so calc AB is basically just the first part of calc BC

[frail elm]

yo

[radiant remnant]

it’s not really meant for a field like science, it’s just elementary calculus

[frail elm]

any tips on how I can make my math steps more readable

look at this for example: https://imgur.com/a/VS2QVeW

I feel like it could be made to look simpler

anyone here use pens?

my pilot g2 died and im curious if you have any pens you guys really like

[mossy marten]

I use the Frixion clicker 07, only pilot pen that my school bookstore carries

[mossy marten]

gotcha, thanks

[digital galleon]

pilot V5 Hi techpoint

[rocky robin]

thanks guys, anything in particular that you like about the pen?

[digital galleon]

The ones I recommended don't leave massive dents in the page. Down side, they can smudge

[rocky robin]

I mean if the pen is good you shouldnt leave a massive dent

unless the pen is running out of ink that just seem like user error

yeah I have the same problem with pencils

they just rip through the page

[keen sinew]

Random question for anyone: what’s the most interesting part about history to you?

[grand sapphire]

the dinasours

[vast wraith]

the rocks (genuinely), then music

history of mathematics also very juicy

[keen sinew]

That’s history? Rocks?

[vast wraith]

yes

[digital galleon]

We don't learn from it.

[graceful flower]

the fact that we know/don't know so much of it

[fresh comet]

geological history is very fascinating for me

if you mean something human based, then... idk?

the 20th century has always piqued my interest

but there's other parts of human that are very interesting too

[fresh comet]

the history of the earth is really damn cool though lmao

[solar hawk]

Rome or Greece or ancient something

[tropic mica]

Yo so why

Is discord primarily guys but moderators on discord servers are mostly girls

[old oak]

It's thankless, unpaid drudgery; men are culturally primed to foist such things onto women

[ripe needle]

That is my favorite part of Linguistics as well

How are you liking the Linguistics server?

i left it, it was not very engaging

if y'all turn in an assignment a couple minutes late do y'all mention it being late or just not mention it and hope for the best

[mortal vortex]

If it's not too late than I'd just not mention it

[tawdry pecan]

it depends on how much your teacher likes you

[daring parrot]

any recommendations on how to refresh my math skill? Been a few years after high school and i wanna go to college and major in math

[tropic mica]

at which lvl

[daring parrot]

wym

[tropic mica]

like is it precalc that you need refreshment etc

[fresh comet]

okay I just want to see something

to anybody who sees this:
what is your opinion on Axler’s Linear Algebra Done Right?

[ripe needle]

Better question: Are you speaking about 4th or 3rd edition.

Most people scream about determinants but determinants is in the 4th edition.

[fresh comet]

4th

[flat harbor]

i studied with it and it was absolutely fine

[solar hawk]

determinants were in the 3rd edition too

they were just at the end

and dami says

done terribly.

apparently

allegedly

[ripe needle]

Yeah it basically doesn't count from what everyone says. Hence the 4th edition

[flat harbor]

im always gonna be on this position

[solar hawk]

im still gonna read the 3rd ed

just cuz i physically own it

and i already started it so long ago

[ripe needle]

From what I understand the way he doesn't do determinants is perfectly fine, he shows how to do LA without it.

[flat harbor]

that if ure someone whos never learned a Thing before then u shuld be approaching all advice abt studying that thing with a massive grain of salt

it u read ladr and think determinants are done wrong... just read abt determinants from another source

[solar hawk]

thats pretty smart i never thought of that

[flat harbor]

in a world where u can access pretty much any txtbook u want, textbook choices shuld be the last thing to have strong opinions abt

[ripe needle]

100% this

Every subject I use 2-3 textbooks

[flat harbor]

yea like

a lot of the times i think just reading the same paragraph written by two different ppl helps me understand it better

a lot of the times i think ppl first learning a topic fixate too much on "im reading [author]" rather than "im learning [topic]"

[fresh comet]

agreed

[flat harbor]

u presumably grow out of it so i guess thats fine

[ripe needle]

I understand higher level courses, but it's crazy to me how many people in book recs spend weeks trying to find the perfect middle school geometry book like in the time it took you to ask about it 10x you could have just grabbed any book and gone through it by now

[flat harbor]

id agree depending on where higher level lies

[fresh comet]

what about teaching though?

if a teacher wanted to teach from a book, should they pick LADR?

[flat harbor]

i rly only think it means anything to minmax txtbook choices if u know how to get thru a book to a satisfactory point on ur own

[flat harbor]

thatd involve more tangible questions that u can ask abt a textbook

[velvet dagger]

To be fair middle school geometry to them feels like higher level math to us

[fresh comet]

fair enough!

my opinion on LADR doesn't go either way

[flat harbor]

i also assume if ure someone whos teaching smth

uve looked at it for long enough to have fantasised abt giving courses on it anyways

so u know what u want from a textbook and what kind of experiences u wanna reinforce

[ripe needle]

Yeah but someone who doesn't know anything about that could go through that faster than say a uni student learning complex analysis for the first time.

At that level there's a lot more resources online such as YouTube and more amount of people can help them such as in this discord. and variance between books isn't as such a degree as maybe between LA books.

If you have multiple people over multiple days telling you to grab a book, you should listen instead of thinking "Nah I should just ask again in 2 more days, these 40 answers don't know what they're talking about"

[flat harbor]

i think its our responsibility to just not engage those kids

[velvet dagger]

I'm not agreeing with them so much as saying

[flat harbor]

we're enabling the intrusive thoughts

[ripe needle]

I stop after the second or third time

[velvet dagger]

It's kinda the same reason why, if you're not careful, middle schoolers doing y=mx+b will see "algebraic geometry" in the advanced channel

And think oh yeah this is where I should be asking

Because to them that's advanced lol

[ripe needle]

True

Now we have #advanced-algebra

[flat harbor]

the service we provide to middleschoolers by operating help channels is dumping money into the money hole

i doubt any of them evolve to become great discussiers...

[fresh comet]

I mean I went from help channels to discussier

so they can too

[flat harbor]

i smtimes see them try

i guess thats the nature of long term investment

[fresh comet]

hmm

idk I just forced my way in lmao

now I live in two worlds on this server

[jagged forge]

one time someone posted in #algebraic-geometry asking about "al khayyam's cubic solutions" which is in fact, both algebra and geometry, but sadly not algebraic geometry

[flat harbor]

i think it shuld be noted that like

such a small amnt of ppl in chat isee are conversable

[fresh comet]

am I conversable

[jagged forge]

no u suck

im sorry that was mean

[flat harbor]

i think theres more than one piece of evidence suggesting it

[ripe needle]

Not Dami with the react 😭

[velvet dagger]

I wondered if someone would catch that

[fresh comet]

I shut down one of his jokes and this is how he gets back at me

lmao

[fresh comet]

hmm

[ripe needle]

Which one

[velvet dagger]

Nah this wasn't revenge so much as

The fact that you ruined it makes you suck

[ripe needle]

Allegedly

[fresh comet]

so true

dw I tell myself that 50x more than everyone else combined ever will

[flat harbor]

gamblers fallacy chat we gotta cut our losses while we can

[jagged forge]

ok now ur just making me feel bad

[flat harbor]

close rhe help channels and this chat will flourish

[jagged forge]

here, have a cookie 🍪

[fresh comet]

my bad

sorry

[jagged forge]

STOP DONT APOLOGIZE

[fresh comet]

???

[jagged forge]

now i feel even worse!

[fresh comet]

what why

[velvet dagger]

#discussion message this was it

[flat harbor]

damb. u made him cry

[jagged forge]

i feel bad for making you feel bad enough to apologize

[fresh comet]

what I felt bad for making you feel bad 😭

[ripe needle]

Oh that wasn't bad at all

[ripe needle]

I don't even think anyone noticed that whole convo except you two lmao

[flat harbor]

"then why did you ruin it?" is so raw

i can feel the anger

[velvet dagger]

Wait a second

[flat harbor]

the soy anger

[fresh comet]

I'm a killjoy like that.

[velvet dagger]

Did I have a dyslexia moment?

[fresh comet]

wdym

[velvet dagger]

I thought you said "more like asking harpz to help hayley"

And was like yeah the joke is they're the same

[fresh comet]

oh

[ripe needle]

lmfao

[velvet dagger]

I thought you didn't get it, and when you were like yeah I did

[ripe needle]

bruh moment

[velvet dagger]

Then it seemed like you were just correcting an obvious joke to kill it

[fresh comet]

bruh that's why I said harpz to help harpz lmfao

[velvet dagger]

And I thought wow okay no fun

Okay yeah Hig you're fine now

[fresh comet]

calling me hig instead of hgr

(I'm okay with it)

[jagged forge]

higgins

[velvet dagger]

I'm just reading your current nickname!

Didn't even know hgr was a thing

[fresh comet]

ah

do you remember me as ING

[jagged forge]

human growth reaction

hgr

[ripe needle]

You're Hig because you can never be Her

[velvet dagger]

Ah right you're ing, I forgot about that

Or were idk what you go by precisely

Is this a bit or a new name or what

[fresh comet]

I changed my name on April fools but I was the only one who wasn't kidding

[fresh comet]

it's a new name

[velvet dagger]

Gotcha

[fresh comet]

higher, hgr, hr, hig, whatever

it's all fine to me

I like hgr because it looks nice to me idk

[velvet dagger]

I have amnesia wrt old usernames since we didn't talk a ton so I probably will just know you as this now

[fresh comet]

and it's 3 letters for 3 letters (ing -> hgr)

[fresh comet]

yeah that makes sense

amukh and the others had a harder time adjusting lmao

speaking of which... it's about time to get rid of this bra-ket name lmao

[velvet dagger]

Oh it's bra-ket

[fresh comet]

blame hayley and metal

they started it

[velvet dagger]

I was like wait is the her part your pronouns? Then why do you have he/him pronoun role?

[fresh comet]

😭

[ripe needle]

100% my first reaction too lol

It took me a second to figure it out

Hence everyone saying "Hig"

[fresh comet]

I literally didn't even realize

until just now

that it could be misinterpreted like that

😭

[ripe needle]

It's okay this server is very welcoming of your community

[fresh comet]

now I am higher!

let's see how long this username lasts until I just end up reverting to Higher...

[ripe needle]

Isn't that what it was before?

[jagged forge]

are you positive recurrent or null recurrent

[fresh comet]

yeah it was

sometimes I see people with exclaimation marks at the end of their names, so I'm trying it out

[ripe needle]

I remember you as Higher and ING, everything else I delete from my brain

[fresh comet]

those were the only two names I've ever had

on mathcord, that is

[ripe needle]

You had like 3 variations of ing

[fresh comet]

the only other one was the bra-ket name

[jagged forge]

the only two names i've had are suremark and suremark MSC2020 60G40

[fresh comet]

ING, ing, and ?

oh

[ripe needle]

idk

[fresh comet]

(ing)²123

that one

[ripe needle]

60G40 Stopping times; optimal stopping problems; gambling theory

[fresh comet]

all of the weird names I've had are basically because of helpers shenanigans lmao

[ripe needle]

Yeah that cursed thing

[fresh comet]

some of them will change their names to smth weird

and then I follow suit

oh actually my user name was

.

for 2 hours

lmao

[velvet dagger]

Is there a username history?

[ripe needle]

@jagged forge

[fresh comet]

no I just remember them

[velvet dagger]

Ah

[fresh comet]

the only other username I've ever had on any server was my first

"grief beyond belief"

[jagged forge]

yea 60G40 is stopping times and stuff which i think is related to martingales

i mean it is right next to it

i want to do probability tonight but i need to look at this model theory textbook and figure out whether i should ask to join the model theory reading group

[ripe needle]

Probability can wait

[fringe summit]

I saw stopping time regimes come up in harmonic analysis/GMT/pde stuff today

[ripe needle]

https://tenor.com/view/curiosity-curious-intrigued-interested-interesting-gif-14505707

[jagged forge]

idek what a stopping time regime is

[fringe summit]

They will learn to fear and rejoice our coming

[ripe needle]

IIRC it's basically as it sounds. You will continue to gamble until you've made 50% or lost 25% of your starting cash.

[fringe summit]

https://arxiv.org/pdf/2103.12497 came up here

[ripe needle]

In stock markets and FOREX, whole numbers and Fibonacci sequences are common stopping times

[fringe summit]

This is definitely something else

[ripe needle]

Oooooh

[jagged forge]

i mean ik what a stopping time/rule is, idk what regime means

[fringe summit]

Likely related

Since it’s about a binary tree of cubes

[fringe summit]

https://open.spotify.com/track/5CSHAq8NHDcCofVzAEmeiy

@fervent pebble

[fringe summit]

Nasty stuff

[ripe needle]

Yeah I'm reading about regime stuff now

A lot of it is in trading papers

[fringe summit]

Saw some group of 3 working through this exact condition (and the generalization in the follow up paper made by stitching this together iteratedly) today

Very nifty to see stuff worked out

[fringe summit]

Ominous

[jagged forge]

the only thing i found googling about regimes were regime switching models

like something called markov switching multifractal

[ripe needle]

Yeah I saw that

It seems "Regime" doesn't have a standard definition and it's whatever the author defines or uses in their paper.

@jagged forge Should @fresh comet learn C++ or C#

[jagged forge]

uhm, i don't know much about their background, i'd say neither language is particularly beginner friendly, but c++ much less so

[fresh comet]

I've done some Java in the past

[ripe needle]

He's new to anything programming, first year uni student

[jagged forge]

ah. c# is like java

[ripe needle]

Then you can go right into C#

C# = what Java was/is supposed to be

[fresh comet]

or maybe I should just go pick up python

and learn C#/C++ later

[jagged forge]

how proficient are you in java?

[ripe needle]

Well I think you should do both, and I don't think the order of which you learn matters.

[fresh comet]

idk what proficient means

[jagged forge]

did you do, like, a project yet

[fresh comet]

I would probably say "not too proficient"

[ripe needle]

Could you make something right now? Or will you be balls deep in a tutorial

[fresh comet]

probably not?

I can't tell tbh

projects can be so varied

[ripe needle]

Yeah but can you do a for loop off memory lol

[fresh comet]

yeah

[ripe needle]

Some people can't even do that

[fresh comet]

I haven't touched Java in almost a year but I still remember the basic stuff

if statements, loops, methods, classes, arrays, etc

OOP stuff I've kinda forgotten

inheritance and whatnot

[jagged forge]

python has a little bit of oop but it's pretty invisible a lot of the time tbh

[fresh comet]

I guess the most substantial thing I've ever made was a re-creation of a certain flash game, albeit very scuffed

it was done entirely on Eclipse though

so idt that would count as a project?

[jagged forge]

isn't eclipse a code editor, why would that make a difference?

[fresh comet]

idk, I've never known anything else

[jagged forge]

is it only a real project if u do it in vim

[fresh comet]

and I'm not sure what "real" programmers use lmao

Deltoid recently got me to download VS Code

[jagged forge]

vscode is nice

[fresh comet]

idk how making a project works tbh

[jagged forge]

well really i mean, anything that's like, not just a homework assignment

something that has a few different pieces to it

and requires a little bit of craftsmanship

obviously it can vary widely in scale

[fresh comet]

well yeah but I meant like

I don't know how programmers actually make their projects lmao

like what do they use

[jagged forge]

oh, i misunderstood mb lol

[fresh comet]

what tools/software do you use

and how do you do it

[jagged forge]

well it's less about the tools imo, and more about how you think

i mean tools are important but code design is more universal than that

[fresh comet]

makes sense

[jagged forge]

some people will insist you make uml diagrams for everything

and sometimes diagramming makes sense

[fresh comet]

but surely you don't use one IDE for an entire project right

[jagged forge]

uhhhh

i do

lol

[fresh comet]

hmm

[flat harbor]

i always felt like smth like this when i first did coding

my first foray was into minecraft modding

[jagged forge]

here are like, the most important things for making a project imo

[flat harbor]

and i felt an insurmountable difference between my code and the pros bc they used multiple files

[jagged forge]

1. have a clear enough idea of what you want to make

2. figure out the different pieces involved in making the thing

uhhh

3. make the pieces?

[fresh comet]

that doesn't sound so different from what I've made before ig

it's the details that ig I don't really understand how programmers do it

[jagged forge]

so like, is there an example you're thinking of that's like, you can't imagine how that could be done

[ripe needle]

Transitioning from Java to C# should be pretty easy to you

[fresh comet]

hm

wait hold on now I'm confused by my own confusion

[ripe needle]

If I had to use more than 1 IDE for a single project I'll just quit

[fresh comet]

idk I guess I never felt like anything I made in the past was a "real" project ig

[ripe needle]

That's normal

[fresh comet]

so I always thought that programmers were making things way above and beyond

[ripe needle]

Coding is probably the biggest imposter syndrome of anything in the world

[fresh comet]

but I suppose the process really is similar

[jagged forge]

i remember feeling that way when i was reading other people's code as a roblox programmer

[ripe needle]

You'll be surprised how simple a lot of big projects are

[jagged forge]

i was like, how tf does anyone write 10,000 lines of code

[ripe needle]

It's not more complex, it's just more

[fresh comet]

I guess my biggest issue is like lack of experience

once I make a real project, I'll understand better ig

[fresh comet]

my largest ever was like

[jagged forge]

yeah probably

[fresh comet]

2k lines

lmao

but... it definitely wasn't super efficient

[jagged forge]

let me see how many loc my project at work is

[ripe needle]

When I made my first game I realized it wasn't any more complex than the MVP, it wasn't more complex classes, it was just more classes. More art. Etc

[fresh comet]

I think my scuffed flash game thingy used... 4 classes?

[jagged forge]

yeah sometimes the name of the game is scalability

[fresh comet]

but tbh they were not too complex

[ripe needle]

Yeah and you could really flesh that by making it 40 classes, pretty much copy + paste

[fresh comet]

so the copy paste rumours are true...

400k lines of code lmao

and then the linux kernel is like

30 million lines of code or smth

[ripe needle]

I don't even know my biggest project

The F-35 has ~8 million LoC

[fresh comet]

hmm

that would be fun to make

[jagged forge]

too easy, u can do it in 1 line of code

[fresh comet]

knowing me though, it would probably take like idk

forever

[ripe needle]

I know someone who worked on a flight sim and that I think was over 1 million LoC

[fresh comet]

or smth

I sucked at doing graphics stuff

[ripe needle]

Okay I know it was over 1 million but I don't know how much

[fresh comet]

I don't expect that I've suddenly gotten better in my 1 year's absence from coding

[jagged forge]

life←{⊃1 ⍵ ∨.∧ 3 4 = +/ +/ 1 0 ¯1 ∘.⊖ 1 0 ¯1 ⌽¨ ⊂⍵}

[ripe needle]

You still have time to delete this

[jagged forge]

this is in fact real code btw

[ripe needle]

Yeah APL is cursed

[fresh comet]

anything animation/graphics killed me idk

I can try GOL tho

[jagged forge]

whats that

[fresh comet]

game of life

[ripe needle]

Yeah you can start with any project, then add to it. So the Game of Life, there's tons of variations, you can add rules, change the board shape, etc

[fresh comet]

I hate typing so I am becoming amukh

with his abbreviations

[jagged forge]

lmao

[fresh comet]

wait wtf

Salagos is light blue

very active

[fresh comet]

hmm
