well volume of solids of revolution

[timid bronze]

try seeing if organic chem tutor has that

or any other yter

[real condor]

thats my savior

[timid bronze]

unless u like reading

[real condor]

he always comes in clutch

[timid bronze]

me too girl

😂

gl on ur midterm :p

[real condor]

ok im at my dorm now im gonna lock in thanks for the advice

[timid bronze]

Np pls get ur sleep dude

[real condor]

worst case i get the volume stuff wrong but thats only gonna be like 2 questions so

hopefully other topics go well

@true zinc

Rate out of 10

[true zinc]

rate what out of 10? The poem?

Imma just say this, we are HORRIBLE at reading or analyzing poetry, literal worst choice for someone to review it

[keen relic]

But... but... Don't you feel the deeper meanings in those words?...

Amazing what the human brain is capable of under some circumstances...

Mathematically of course.

@true zinc don't leave me hanging

[true zinc]

Not...really? We don't gravitate to poetry as much as we do prose, by a long shot

frankly we don't understand most poetry

I'd say ask someone else

[keen relic]

Ok Ryan, thank you for the honesty.

[real horizon]

Wow

This poem really opened my eyes on the matters related to how the universe works

[keen relic]

Thank you Ramon!

[real horizon]

Anytime darling!

@true zinc I think you could use a collection of artistic poems like this one

I'll try to convine Paul to send you his

[main elbow]

i think with poetry you just have to find something youre into, that you can connect with, at least to begin with

trial and error mostly

[real horizon]

@keen relic

[keen relic]

[main elbow]

music too can be a great way, obviously not all music is necessarily poetic but theres certainly plenty out there that is

[neat lintel]

this is offtopic, but should i block my sisters' access to youtube shorts?

I don't like how addictive it is

[fresh comet]

[gusty socket]

i say yes

personally

[brave shell]

You should make her watch nothing but 3blue1brown shorts, at which point she should get sick of the whole platform.

[latent edge]

Make her watch videos by Ram Murty or anything related to analytic number theory. This type of addiction is better

[gusty socket]

they shouldn’t really have youtube at all imho

but this is more extreme of an opinion than most people are willing to have

[latent edge]

And please don't watch Youtube shorts

Another fancy name for TikTok

[neat lintel]

thanks, I will mathpill them

[latent edge]

https://youtu.be/3poB-ZIPolU?si=y5ysdjoDsU6v4r4L

[fresh comet]

wait, why do you say so?

[gusty socket]

i think youtube is such a waste of time when you are exploring all the joys and wonders of life

[latent edge]

Also getting addicted to LMFDB is good

[fresh comet]

[gusty socket]

like children should not be on youtube or youtube kids

[gusty socket]

or whatever

[fresh comet]

that is certainly a position I've never seen before

[vivid halo]

iPad parenting

[gusty socket]

like it’s probably okay if you as a parent are an active participant in your child’s interaction with it

[vivid halo]

Yeah absolutely

[coarse bridge]

me with tiktok, ig reels, youtube shorts, etc.

[neat lintel]

I very much agree because my sisters aren't parented when they watch it

[coarse bridge]

i agree its not good tho lmao i barely use em

[neat lintel]

Kids should watch with family imo

[gusty socket]

because you can teach your kid to use the internet responsibly and help them become more literate when it comes to analyzing media

[latent edge]

IG reels is full of bullshit and "cs majors are cooked frfr ngl vro"

[coarse bridge]

holy fuck ig reels is like gutter quality

LMAO

[gusty socket]

this is a probably a really great use of youtube

[latent edge]

It would take me like 1 second to find a bullshit IG reel about cs majors

[gusty socket]

also there is a lot of real educational content on youtube

[coarse bridge]

yeah

[latent edge]

Or girls showing boobs or some shit

Disgusting

[gusty socket]

but none of it is on youtube kids

for some reason they have saved youtube kids for only animated gore, and saved all the things that are healthy for a child’s development like introductory topology for the “real” youtube platform

[pure cliff]

Fantastic stuff

[latent edge]

Time to develop a new YT for kids

Hold my software engineering

[gusty socket]

are you stochastic bifurcation

[pure cliff]

Yes

[gusty socket]

okay

[latent edge]

Lmao my guess was right after all

[gusty socket]

oh yeah i bought pie this morning

let’s go

[coarse bridge]

\sqrt{-1} 8 \Sigma \pi

[neat lintel]

you should make 3blue1brown videos appear first in the feed

[gusty socket]

honestly yes they should, and then as soon as you watch 10 of them they should never show you 3 blue 1 brown again

[latent edge]

Watching too much 3B1B can make you a crank

[fresh comet]

ohhh, that explains a lot lmfao

[coarse bridge]

whats wrong w 3b1b?

[pure cliff]

Wait I thought U legit figured it out ages ago

[fresh comet]

nah, I didn't suspect a thing

[pure cliff]

I am dissapoint

Jk

U good

[fresh comet]

but everything does line up

[coarse bridge]

i didnt interact too much with you so i didnt realize

[pure cliff]

I missed talking to you

One day we can talk for real like the old days

[sturdy gulch]

weird question: does the IVT apply for complex numbers?

[pure cliff]

Nope cause of the 2 dimensional ness

But you have something even more insane

Picard's great theorem

Is the complex analysis version of IVT

[sturdy gulch]

i mean it kind of makes sense ish?? 😭

[surreal sapphire]

i wouldnt say so

[pure cliff]

It's crazy is what it is

[surreal sapphire]

there are multi dimensional versions of IVT

[pure cliff]

Well obviously not on the dot

I told a lie

[surreal sapphire]

and there is also the fact that the continuous image of a connected space is connected

[pure cliff]

White lie

[surreal sapphire]

which i would call the real generalization

[pure cliff]

I just like that theorem

[surreal sapphire]

the issue is that in C you dont get any order

[pure cliff]

Yeah

[surreal sapphire]

so "any point between" doesnt make sense

great picard is a theorem about entire functions only

[sturdy gulch]

hey i mean it was a theorem that i did kind of what to know more about

so

more things to read about yippiee

[surreal sapphire]

while IVT doesnt care about any such thing

[pure cliff]

Do you study any 0ther kind of function in complex analysis hahaha

[surreal sapphire]

yes...

[pure cliff]

What kijd

Kind

[surreal sapphire]

meromorphic functions

one of the earliest big questions in complex analysis is how to construct meromorphic functions with prescribed zeros and poles

this is solved by the riemann roch theorem

and this then inspired algebraic geometry

and is still being researched

also in general one big thing in complex analysis is the notion of locality

[pure cliff]

Ah ok

[surreal sapphire]

a holomorphic function is defined locally by a power series

[pure cliff]

Mmhm

[surreal sapphire]

but the representation may change

entire functions are globally defined by the same power series

and in that sense kind of boring

another big thing is the concept of analytic continuation

[pure cliff]

If you are entire, aren't U determined by an arbitrarily small neighbourhood?

Like determined globally

Freaky stuff

[surreal sapphire]

ye, they are very rigid

consequence of the identity theorem

you can locally write any analytic function as a power series

and well, if you are entire, this will be valid everywhere

so looking at just entire functions is boring

[pure cliff]

Based

Yes meromorphic functions with the poles and shit seem cool

[silk moth]

When answering a question, should i also give the answer or should i only give hints and explanations?

[surreal sapphire]

mostly the latter

you should prioritize learning

and most of the time giving out answers does not do that

[pure cliff]

If it's a question I personally care about

I just write the answer

Cause I want to answer it

If it's boring and easy I go for pedagogical approach

[silk moth]

Ok thanks

[lament bramble]

guys how to turn off notifications?

the good news: out of the seven questions only one was on volume

the bad news: that one question was worth 20% of the test

some more good news: he gives partial credit

some more bad news: no one in class apparently understood that question

curve better carry

[unborn meteor]

is it curve grading

ah sniped

[real condor]

no im only saying that to make myself feel better

he said no curve but honestly

there’s no way he doesn’t

literally like 30 kids didn’t get the answer

and like 10 more just didn’t even attempt it

[naive gazelle]

I want to tale admission in trinity college Cambridge can anyone guide me i am in 10th grade now

[north topaz]

https://www.maths.cam.ac.uk/undergrad/admissions/step

for Trinity the STEP is not required

nevertheless a good score would help your application

basically keep on practicing maths, and the interview weightage is comparatively less compared to Oxford

[naive gazelle]

So what should i do now should i focus on school or olympiad level

[north topaz]

I can check the exact requirements for India if you want or your country

[north topaz]

ideally both, both have their benefits

[naive gazelle]

Im indian

[naive gazelle]

Some people say do research some say focus on school some say do olympiad im very confused can u tell me what should i do

[north topaz]

also which course would you like to study?

[naive gazelle]

Mathematics

[north topaz]

maths right, okay

[north topaz]

there's no need for any sort of research, cause that's insane and if you can do research as a high school student, you must be very privileged in addition to being smart

in the interview they're just looking for you to explain your reasoning

it's okay to not know or to be wrong!

[naive gazelle]

How can i make it to interview

[north topaz]

so everything that you're doing right now, in terms of seeking challenge and getting stuck, would be very beneficial

[naive gazelle]

I can do anything to get in there

[north topaz]

well I mean good grades mostly

your personal statement on UCAS might also help you give a little bit of extra impression

[naive gazelle]

Only good grades?

[north topaz]

the personal statement format is changing

you'll have to answer 3 open-ended questions

https://www.ucas.com/undergraduate/applying-university/writing-your-personal-statement/new-personal-statement-2026-entry

[north topaz]

good grades + interview

[naive gazelle]

How much grades would be enough?

[north topaz]

let me check

[naive gazelle]

Like percentage

[north topaz]

it's not enough to do regular class 12 syllabus

yeah so maths you have to do the STEP

[naive gazelle]

So what should i do extra

[north topaz]

that's why I linked it

[naive gazelle]

Sixth term examinations paper

[north topaz]

basically that's Cambridge's admission exam

[north topaz]

yes

[naive gazelle]

Is giving jee necessary ?

[north topaz]

no

besides JEE is only applicable for Indian unis

the rest of the world doesn't care

[naive gazelle]

I have seen people with good grades can not make it to interview

[north topaz]

yeah cause in the interview they really get a sense for who you are and what you can do

that's very common unfortunately

I heard all sorts of people being coached when all the uni wanted to see was their true personality, something that can't be coached

[naive gazelle]

How can i prepare for step ?

[north topaz]

and besides like there's way more people who want to apply than there are spaces

not as crazy as JEE but still

[north topaz]

in the link I sent

https://www.maths.cam.ac.uk/undergrad/admissions/step

there are links inside to past papers and good advice in general

also

Using STEP allows us to make offers to many more candidates who show mathematical potential at interview, but do not have quite enough mathematical knowledge and skills because of educational disadvantage, then provide sustained support to motivate them and help them prepare for the exam and for mathematics at University level. So STEP is also a powerful tool for widening participation.

[naive gazelle]

I have to give step before or after interview

[north topaz]

Cambridge believes it's fairer to test using their own exam

[north topaz]

before

[naive gazelle]

If i get good grades and also give a good ucas statement would they call me fpr interview

For**

[north topaz]

there's no guarantee

all you can do is try to maximise your chances

don't try to control what you can't control

[naive gazelle]

Isnt there anything ?

Which can guarantee

[north topaz]

no, that's the truth

[naive gazelle]

So will they consider my 10th percentage beside mathematics

[north topaz]

there are a lot of situations in life where hard work isn't 100%
it may be 70% or 80% so I'm not saying it isn't important

just not 100%

[naive gazelle]

I can do anything i only sleep 2 hours to not waste time

[north topaz]

yes in the screenshot I sent, they consider 5 of your subjects which are relevant
so say maths, 3 sciences, and Hindi or English or something

[north topaz]

actually you're only hurting your performance by not getting enough sleep

the science of sleep is decades old by this point

[naive gazelle]

Can i tell u smthg

[north topaz]

yeah?

[naive gazelle]

Just don’t think im mad

I want to make a new branch of mathematics with very less rules that can help to solve unsolvable questions

In india people only see grades

That’s why i want to come to Cambridge

[north topaz]

yeah, that's a great point, and Indian uni system sucks man

https://www.youtube.com/watch?v=XBAZyg_1luY

I watched this video recently and all the toppers went to the US (a few went to the UK as well, but you get what I mean)

[naive gazelle]

Is there any book which can help me ?

[north topaz]

so yeah I definitely think Western uni education will be more liberal and progressive, more freeing

[north topaz]

you just need to try your best but don't overwork yourself of course

just try and pray for the best

if it's not Cambridge or Oxford, there are a lot of other unis in UK or other Western countries which will accept you

just depends on your family's finances and whether they are willing to support you financially

[naive gazelle]

I only want Cambridge

[north topaz]

I imagine for Cambridge they will ofc

[north topaz]

you're not giving yourself the best chances by only applying to Cambridge

you can't apply to both Cambridge and Oxford btw

[naive gazelle]

Is there any good university u would suggest me

[north topaz]

you have 4 other choices in UCAS

[naive gazelle]

For mathematics

[north topaz]

why not try UCL and Imperial

[naive gazelle]

Are they good ?

[north topaz]

https://www.theguardian.com/education/ng-interactive/2024/sep/07/the-guardian-university-guide-2025-the-rankings

basically Edge Hill is a small uni, not sure how they got up there

the other choices are great however

[naive gazelle]

Can u please suggest me some book that can help me ?

[north topaz]

Warwick also, I know I'm just basing it on name reputation and not teaching quality

[north topaz]

I don't think you actually need a book
you need to talk to people who are in university or have graduated, doesn't matter where actually

like on Reddit there are a ton of uni forums

you need different perspectives so that you can make your mind up

you don't need to have life all figured out of course

basically you need to borrow the life experience of people who are older than you

life experience and maturity, yep

https://www.thestudentroom.co.uk/university/personal-statements/mathematics/

also there are a ton of sample personal statements here

I do hope you're saving all of these links for later

it's a shame in many Indian schools unis don't come to give advice and answer questions
or even in a ton of schools, there isn't a university counsellor or they're not helpful at all

[neat lintel]

[naive gazelle]

@turbid ocean

this trig identities sheet is pretty decent I feel

don't memorise everything on here of course

but most importantly it has the reference angles as well as the pi/2 - t identities

[turbid ocean]

OH MY GOD DUDE THANK YOU SO MUC

[north topaz]

no worries!

[turbid ocean]

It was actually about the cos ones, these ones feel kinda tricky since we gotta memorize everything (we have no access to any resources including calculators)

in tests ofc

bc there was a function f(x)=(x2-cos2x+1)/x3

and we basically had to prove that f admits an extension of continuity in x0 as x0=0 (it's an undetermined form so had to use some tricks to get rid of it)

it's geometry in algebra analysis and it's kinda confusing

but thanks man I really appreciate the help

[pure hollow]

[long pumice]

The geocentric model of Ptolemy from "Alexandria" may have been an insider joke about appearances and underlying mechanism in top engineers circles for a very long time. See how plain artistic Ptolemy solution looks. Imagining top engineer math level people building new bridges and ship models very seriously with lots of solid practical tune on sound simplified underlying mechanism models. Ptolemy looks too shallow at investigating possibilities and too cheap on drawing duct-tape style complications. Mind that they marginally cared of most of the untouchable too far away night sky and that they were still telling kids Illiad like greek gods stories with sky pattern elements included.

[vast wraith]

what

[long pumice]

mind potential engineer joke all the way, the Ptolemy model is simple to directly apply to predict the apparent movement of planets an Earth observer should expect, like a formula to apply for a direct result without deeper model considerations

[visual topaz]

Oxford not 2nd in Law wtf

[long pumice]

Now really proving with solid confidence a better than Ptolemy WYSIWYG model may not have found practical traction really until the times of Nicholas Copernicus (co per nicus). The interesting discussion to really prove the geocentric model out, not only to find a simpler model that naturally looks a more plausible explanation but some less likely things are known to happen too.

[static loom]

try solving it for N = 1 first

[lethal merlin]

why is my college so eager on teaching me how to solve system of equations matrices
how will matrices help me in my future career of bookkeeping. seriously how?

[true zinc]

What's your major, if we don't mind me asking

[lethal merlin]

bookkeeping/accounting

[true zinc]

Systems of Equations could possibly come up in accounting, linear is a LOT more powerful and useful than just for solving systems, but frankly, you probably won't see too much of it, but it is useful as a tool to have in your back pocket

[lethal merlin]

i know how to do systems of equations. they are useful yes but what is the point of matrices. they serve no purpose. my whole class doesnt get it. all of us are basically getting fucked over and over every single class cause we can understand matrices

[true zinc]

just off the top of our head, the main examples we can think of; solving differential equations, lie theory, functional analysis, operator theory, abstract algebra in general

[true zinc]

Matrices can be considered linear transformations between vector spaces

[lethal merlin]

my dad has been an accountant for 20+ more years and he hasnt used this once.

[true zinc]

Well yeah, these come up a LOT in pure maths mainly

[lethal merlin]

how is this gonna help me file my clients' tax returns dawg 😭

its just useless math. i wish they would teach math they will actually be helpful in my career area

[true zinc]

It's less about being useful in 5 years but more passing your course

[lethal merlin]

true

[brittle socket]

Use matrices to solve systems of linear equations?

[main elbow]

as with all things in school, it wont help you till that one day that it will

tbh you could ask your professor to give some motivation as to why youre learning it

[true zinc]

https://www.daytrading.com/linear-algebra-finance

[lethal merlin]

i get you but i dont think matrices will serve me purpose in the future.

[main elbow]

maybe not, but maybe

XE

[true zinc]

Matrices can represent systems of equations, sure; but in general, a matrix is nothing more than a linear transformation (T \colon V \to W )

[lethal merlin]

shit im just tryna pass. i dont even remember any math that im learning after like 2 or 3 months. i remember algebra and shit but i havent remembered any math that i've learned after 12th grade. i study for it before my test, when my test is over my brain just throws all the knowledge in the recycle bin

[true zinc]

Consider the matrix A defined as (A := \begin{bmatrix} \cos{(\theta)} & -\sin{(\theta)} \ \sin{(\theta)} & \cos{(\theta)} \end{bmatrix} ) acting upon some vector v defined as (v:= \begin{bmatrix} v_1 \ v_2 \end{bmatrix})

[lethal merlin]

huh 💀

[true zinc]

where did we forget the bracket

aaaaaaa

[fathom swallow]

TCC, CEO(s) of Mathcord

[true zinc]

found it

[lethal merlin]

any math after 12th grade is useless FOR THE AVERAGE person imo

but for future scientists, doctors, professors, teachers, they need it

[true zinc]

now we can succinctly write this as:
[
\begin{bmatrix}
\cos{(\theta)} & -\sin{(\theta)} \
\sin{(\theta)} & \cos{(\theta)}
\end{bmatrix}

\begin{bmatrix}
v_1 \ v_2
\end{bmatrix}
]

and what does this become?

This becomes
[
\begin{bmatrix}
v_{1}\cos{(\theta)} & -v_{1}\sin{(\theta)} \
v_{2}\sin{(\theta)} & v_{2}\cos{(\theta)}
\end{bmatrix}
]

[true zinc]

Sure, but I also feel that HS should teach some maths better, because so much is just...lost and at-least in the US, when students come to uni, they struggle like hell

[zealous garden]

**reorienting

What you're referring to as a rotation is in fact a reorientation, or as I've taken to calling them "Equivalence classes of rotations". Rotations are real, and you do use them. But when using matrices you have to use Equivalence classes of rotations, along with an identification each 2pi radians. The resulting Equivalence classes of rotations actually don't have a sense of direction, and so can hardly be called rotations

[lethal merlin]

i went to one of the best public high schools in the state and country so im sure they thought good math at my school

quick clarification: that 2m + 1 should be a 2m - 1 right?

at most m - 1 positive roots, symmetrically at most m - 1 negative roots, and then maybe 0 so 2m - 1?

idk where +1 comes from it's gotta be a typo unless I'm going nuts >_>

Hi

I wanna ask, are we able to create threads? Or we need permission from mod

Something like this

@limber thunder Sorry for the ping btw

[limber thunder]

yes I meant to reply to this lol,~~ only mods have perms for creating threads afaik~~

and there's a few in e.g. the advanced channels

[narrow carbon]

I see, I wanna create a thread for reviewing real analysis (probably starting from Abbott) -- Also I wouldn't be alone there, there is one of my friends as well he will join me.

So can you please let me know what would be the procedure?

[jagged forge]

i think we can make threads in the advanced channels actually

unless this was changed in the last few months

[limber thunder]

yes this seems to be the case

[jagged forge]

yeah we definitely still can (unless the thread button being there is lying)

[limber thunder]

can you try and make one in #real-complex-analysis

[narrow carbon]

If so then anybody can create thread. Wouldn't it be a bit messy?

Like having bunch of threads

[narrow carbon]

Sure.

[jagged forge]

indeed, we are trusted with this incredible power

it’s limited to the advanced channels tho fwiw

[limber thunder]

there is some precedent about moderating those #changelog message

but since the adv channels are locked behind a role (that is self-assignable, but still) it's not much of a problem

[narrow carbon]

Makes sense. Thank you both of you, for the explanation

everything is systematically getting more refined and it might not be immediately bear the fruits or be obvious as to why it needs to be done this PARTICULAR way (especially to people who have been largely unfamiliar for most of their lives so far) but rest assured that one day youd be thankful that it was done this way (certainly not the pedagogy part but the grinding that youll go through)

[surreal sapphire]

i mean you wont use matrices for bookkeeping (which is probably just juggling excel)

you have to ask your school why they want to teach it to you

the only argument i could come up with is you have to learn some form of mathematics to hone thinking abilities

i mean, you might have to solve linear systems, but the computer will do it for you

but if you see why solving systems of linear equations is useful, then matrices can be thought of as just a compact way to write them down

[quiet geode]

schools dont know that most of the time, they pick up trendy shit so that they dont lag behind

[surreal sapphire]

not where im from

[quiet geode]

the world is not where youre from too

[surreal sapphire]

the same applies to you

i wasnt making a general statement, you were

[quiet geode]

most of the time

[surreal sapphire]

besides i think this is wrong even where you are from

[quiet geode]

yeah sure lol

[surreal sapphire]

school curricula are politics, they have to give some reason to create them

political processes tend to be overly complicated

[quiet geode]

nice assumptions, love the delusions

[surreal sapphire]

i think in this case its more of the opposite

matrix computations by hand used to be necessary

[quiet geode]

could be im just as ignorant

[surreal sapphire]

so they are still taught

[vast wraith]

it’s not long since they stopped teaching doing calculations by slide rules and log tables

70s

[burnt dune]

why is everyone like "my fav equation is boundary of boundary of somehting is 0"

when this is like false

like shouldn't this be only true in the context of like

de rham cohomology with the boundary being the exterior deriavtive?

or the boundary operator on delta complexes?

the boundary in point-set tho doesn't agree with this at all no?

[upbeat shore]

suitably interpreted it's fine

the point is just that the boundary of something should be a cycle

and cycles almost by definition have no boundary

[north topaz]

yeah people used to approximate p-values by hand and shit

[burnt dune]

yeah but i just think it's confusing cuz anyone who hasn't seen simplicial homology will just

get confused as shit

[north topaz]

I mean yeah the problem is that maths education is traditional

you're basing it at least on how teachers were taught themselves 10 years ago

if not older

everything you think is modern, like graphing display calculators?

nope, were around in the 90s

[vestal cloud]

Hellooo, I'm a high school student and our teacher gave us a project, and its about mathematical investigation, but im really having hard time to make more topics
the only topic i have is
the sum ng 7 consecutive odd squared numbers is always divisible by 7 ;>

[north topaz]

(if the TI-81 was around 1 year earlier it would have been the 80s technically)

[north topaz]

are you doing the IB?

[vestal cloud]

what is IB?

[north topaz]

okay so you're not

but your topic could use some more brainstorming, as you could prove that in a page

https://ibmathsresources.com/maths-ia-maths-exploration-topics/

there's a huge list of ideas here

or if you want to generalise this result and do some modular arithmetic and number theory, that could also work

[vestal cloud]

thankss, I hope my teacher approve my topic, cuz i can't even think of another topic and my brain hurts HEHEHEHEH

[north topaz]

no worries!

[grim carbon]

So what do y'all study?

I'm considering studying maths

It just seems quite interesting

[gusty socket]

terryology

[grim carbon]

Stopp 😭

I was joking 😭

Im really curious what do yall do and where did the passion come from?

[gusty socket]

i like topology, i used to be interested in physics and then realized i really liked the math aspect.

[grim carbon]

Topology seems really unique

I also like physics

Im considering a double bachelor thats why

which my local uni offers

Where did u graduate?

Do you find math scary

[gusty socket]

no not particularly

i think the world is scary and math helps us make it less scary

[grim carbon]

That's a line

A bar

[vast wraith]

i also started studying physics but (very) quickly switched over to math

before i had time to learn any physics ehehe

Whatddyal think of jeff cook

[static loom]

john cook?

[grim carbon]

He is a genius who solved the riemann hypthesis

He has a yt channel

He spent 30 something years as an engineer on it

He will publish soon

[static loom]

this isn't even the first false claimed proof of RH in this channel today

[bronze pelican]

Nice great for him

[agile fiber]

if someone solved the riemann hypothesis we would have heard by now

[grim carbon]

Also chatgpt verified the proof

[static loom]

!nogpt

[quasi jetty]

Please do not trust ChatGPT or similar AI tools for mathematical tasks, as they often generate output which "sounds correct" but has numerous factual or logical errors. Use of these AI tools to answer other people's help questions is strictly against server rules (see #rules).

[static loom]

yeah and your name's jeff cook probably

[grim carbon]

Chatgpt is predicitve in nature i dont know why cook would even spend time fiddling with chatgpt altho he claims he doesnt care why fiddle with it in the first place

[grim carbon]

No he's my stepbrother

[grim carbon]

He says it's already known in the mathemethatical world and that these things take time

[latent edge]

I'll be a nice guy and tell you stop, get some help

[agile fiber]

not if it's a millennium prize problem

[grim carbon]

Tell him he's the genius that solved of

It*

[grim carbon]

Wdym?

[glass peak]

It’s such a famous problem that the second it was solved everyone in maths would know about it

[grim carbon]

He seems p confident

Iddk as a gullible amateur math youtube viewer that seems reassuring so hes probably right?

Idk maybe im reaching

[glass peak]

Lots of people claim to have solved it

[grim carbon]

He could be different

He spent 30 years

And some mathematicians already read his stuff he claims

[glass peak]

The chances of it being some no name guy from YouTube are unbelievably slim, and you need to stop just believing everything you hear on the internet

[grim carbon]

And he comes across as the bigger guy in the debats in the comments of his videos so that tells you who to root for

[glass peak]

Im genuinely wondering if im being trolled now or just talking to a 10 year old

[grim carbon]

Im just trolling it's easier to get interesting input like this

But genuinely tho

I wonder

Cus hes so confident

But also kinda smug

Tbh

Somewhere in between

[glass peak]

I would bet all my worldly possessions that he hasn’t but I’d be happy to be wrong

[grim carbon]

Yeah

I should be happy to be wrong

But he kinda smug

[alpine kindle]

they all are

[grim carbon]

True but he has gained lotta traction and traction=legit?

[alpine kindle]

no

not at all

many cults gain a lot of traction

Scientology is not legit

[grim carbon]

He said a bunch of mathematicians looked at his proof and found no error and as an enthusiast i dont know how to swallow that

[alpine kindle]

he is lying

[grim carbon]

but ig it doesnt really do much wondering if hes right or wrong until theres definitive consensus

[alpine kindle]

people lie

[grim carbon]

If

Ig

[alpine kindle]

or bend the truth

or misremember

maybe someone who isn't a mathematician said it was correct and he assumed they were a mathematician

[grim carbon]

Somewhere inside i dont want him to be the guy to have solved the big money maker

[alpine kindle]

well don't worry he won't be

[grim carbon]

Which is kinda judgemental

Oh well i won't then

Worry

[alpine kindle]

no rando on yt has solved the riemann hypothesis

proven or disproven

[grim carbon]

Engineer too

Not to throw shade

Just stating the fax

His personality is also such a smartass

Like bro if you solved the RH why engage in useless quarrles in ur comments

Like u cant be the guy

Ppl who solve shit of this magnitude have aura

This is full on shade ik

"which is why we e-mailed a copy to the top 10 mathematicians today" what is yalls first reaction to this claim

Imma sleep gn my little geese

[ocean harbor]

gn

[limber thunder]

yeah and can it count how many "r"s ate in strawberry yet

[limber thunder]

this is true to some extent, tbh most of the actual smart people ive met doing maths dont care about clout at all

consider that anyone reasonably trying to solve something as long standing as the RH probably should consider the decades of previous efforts, which a lot of these online "geniuses" don't

by now its clear to like everyone in the academic community that RH is not really something tractable by elementary complex analysis

otherwise people already would have a clear idea of whats required to tackle it, if not a proof already

thered be no point in making it a big conjecture

come to think of it I'm very partial on the clay institute offering crazy money for solving something in these problem lists,

• it ignores the fact that math is a collective effort (and this is why Perelman outright rejected the prize money),
• while it garners attention and curiosity it often hurts the mathematical community by forcing it to interact with a ton of people who legit have no idea what theyre doing, as the idea of winning the prize feeds into some people's delusions of grandeur
• it potentially distracts new math students from whats actually important or how they can make a good contribution through research
  and etc

[alpine kindle]

the first of these problems is also why i dislike maths prizes in general

like the fields medal and abel prize

hey yall, so I've got this data that modulates between slow and fast over time that I'm trying to plot. Right now it looks like ass. I was hoping someone had a better idea for a type of plot that I could use instead. rn it looks like this: https://imgur.com/a/CazJl5K

also, idk if this is appropriate to put here, but it seemed as good as anywhere

[ocean harbor]

use tikz

or matlab

[wise wagon]

nah, the graphing software is chill. I got no problem with that, but I mean like what type of plot should I use? For example, a bar graph or scatter plot etc. cos rn, its not very clear as you can see.

[ocean harbor]

not sure

[hardy iron]

What the grelp how can one even fit a curve to a data like that

[wise wagon]

I'm not trying to fit a curve to it

I'm just trying to make it look a little bit nicer

[hardy iron]

The points seem big in the picture and cluttered, I suggest using smaller points and stretches the graph out

[wise wagon]

yeah, nah I can do that for sure. Actually it might be helpful to note that the state is either slow or fast, so I kinda want to indicate that, did you have any ideas for that? cos right now it's just showing when it changes between states.

[jaunty ibex]

My university had a weird obsession over IMO gold medalists, field medal and of course the money that comes from solving stuff like RH

I think I understand the proof and I find it correct. Any thoughts?

[surreal sapphire]

well, its wrong...

the error is probably in the assumption of how many paths there are in this tree

but im not looking at this for longer than a second

[steep timber]

Greeting @surreal sapphire
which tree do you mean? The number of paths in the infinite complete binary tree is the cardinality of the continuum.

top 3 so that I can use another in case it's taken

[vast wraith]

i’m sorry but they all suck

[neat lintel]

i think they are weird too

[vast wraith]

i recommend thinking for yourself instead of asking chatgpt

[grim carbon]

Or asking a forum that's knowledgable on the topic

[icy locust]

thinking, aka instructing LLM to perform chain of thought

[vast wraith]

speak for yourself

[neat lintel]

NumScope doesn't show up in the search results

it's unique but sounds odd

[limber thunder]

nah using LLMs for this kind of stuff is fine for like, a first iteration

precisely for the stage where you just want a ton of potentially bad ideas, to find a good one amongst them

[limber thunder]

numina sounds kinda good actually

[finite wave]

While it’s always important to think for yourself and develop your own opinions, using resources like ChatGPT can be beneficial for exploring different perspectives or gaining information quickly. Ultimately, it’s about finding a balance—using tools to enhance your thinking rather than replace it. Engaging in thoughtful dialogue and questioning information can help sharpen your critical thinking skills.

[neat lintel]

sounds like something ChatGPT would say

[surreal sapphire]

numina is the plural of numen

AHHAHAHAHAHAHAHHAHA

If mods find out, Deltoid will get banned for no reason again

[long pumice]

a VLT array like or GMT mirror composition like space telescope seems to be long due and easily within existing technical capability after 2000 (imagine space station like assembly with docked in components). Some things in this area are suspected to be much easier and much more efficient in space. For instance VLT array interferometry technique would need much fewer reflection in space, if interferometry is even needed at all past initial alignment calibration of a large central obstruction practical telescope design.

(the 2 designs seem obviously very suggestive of outer space applicability)

on a related matter the gold surface on JWST kind of made it cheap, the argument for it seems to be narrow minded over optimization

(cheap achievement, less wolf envy to affect launch morale, no more holes to put in the argument there)

What would you think of the practical mathematics of a mask based space telescope design I recently sketched: https://old.reddit.com/r/askscience/comments/1e5iwvj/ask_anything_wednesday_physics_astronomy_earth/ldtyxia/
"What would be the proportions of an array of large space telescopes capable to resolve Earth size planets up to 200 light years away? Can we just have 16 distanced large mirrors kept perfectly aligned and reflecting through a mask to the light accumulating mirror projecting on the image senzor?"

On the economic side it seems that there could be huge economy of scale by making 16 instead of just one large mirror, like only doubling the total project cost compared to JWST production. Most of the cost seems to be technological research, producing and launching more product pieces can have marginal costs. This argument could have had well larger weight at robotic missions to Mars too. It feels depressive shy exploration and not enough of pragmatic practical economy approach, an area where SpaceX started to dominate with much better economic thinking.

[long pumice]

no discussion about a space telescope array that would really allow us to detect other civilizations or signs of life on other planets with rigorous objective search confidence

being in a galactic nature reserve the nearest outpost of mature past space age galactic civilization may be thousands of light years away, which is on the harder side to resolve, but there should be some peers nearby, at least peer planets with signs of life although almost all of them would not be past the dinosaurs age, we have civilization for only 10K years on Earth, 10K years later we may become a past space age civilization and out of nature reserve wild galaxy status

(it feels we are very out of the wild now, at the top of human civilization today)

[jaunty ibex]

Are you ok?

[gusty socket]

scifi idea

[long pumice]

(almost all of them within 200ly would not have civilization seems more likely correct)

(we got from mostly just fire and stone tools to space exploration and ability to make nuclear energy within 10k years; the fundamental ability to control nuclear energy is very god like power, other fundamental high powers seem on the way like high genetic code understanding and related God like capabilities)

[long pumice]

once we have almost all the fundamental God like knowledge and powers one way or another we are very close to being out of the wild galaxy and join the discussions of the central galaxy world which likely got past the space age and all over the galaxy a long time ago, like 8 billion years ago

we seem to miss that we already have the technological capability to look around the galaxy with much better accuracy to have a much straighter image about the planet level universe around us

[long pumice]

estimating like Elon Musk we should be able to detect signs of alien life before 2030, else the Apollo program took around a decade to land on the Moon since conception, else the fishy slow JWST development lasted 20-30 years

I suspect high public interest on that aspect of closer investigation of the alien worlds in the universe around us

JWST seems to have insisted on some extra ambitious highly optimized research details, there can be much more pragmatic economic approaches

[north topaz]

2030 is in 6 years

what makes you think there's going to be a sudden breakthrough, given that SETI has been active since the 80s at least?

[long pumice]

did you read what I wrote? I was talking about a telescope mirror array in space

[north topaz]

oh you talked about a lot of things other than that

but yeah okay, I'm just not convinced that JWST is a hail mary

yes, it's been very useful for deepening our understanding of space, but alien life is a whole other cateogry

there's the very real possibility we are alone in the universe, for any number of reasons (just one reason being that we are in a simulation, and if we haven't been contacted yet in all of human history, then there's some reason why that is)

[long pumice]

waste all the universe and time just for one blue planet?

[north topaz]

put another way, landing on the Moon just required the right level of technology among other things
it only depended on us humans

[north topaz]

who knows what the intentions of higher beings are

we probably can't comprehend them right now anyway

[north topaz]

there's a possibility that no matter how developed our technology is, we can't detect anything if there's nothing to detect to begin with

[long pumice]

at high enough accuracy we can confirm many search details

[north topaz]

I mean these are philosophical questions not scientific ones at this point

are we alone in the universe?

what is our purpose

we can keep searching but there might be nothing to search to begin with

[long pumice]

imagine to completely map solar systems up to 2000ly away, while actually resolving Earth size or larger planets up to 200ly away

rigorous knowledge about our close intereste neighborhood

[gritty crater]

There are billions of billions of planets out there. There must be at least one planet that has conditions that are suitable for life

[long pumice]

20K ly maps for the 200ly resolving telescope

just separating planet light points would be much easier

[north topaz]

oh yeah this is getting into arguments a lot of people have made before

this line of reasoning

I honestly believe in some metaphysical way that the universe was designed for us to explore

but yeah, I'm not suggesting we repeat the colonial genocide that happened on Earth in living memory, out in space

there is also a very real possibility that there is life somewhere in the universe and we have to develop precautions for that

I just don't think that that life will be anywhere near as intelligent as we are right now

in other words the higher powers gave us a massive headstart at the very least

or that we're alone of course

[north topaz]

I can't explain why but I just know deep down that we're in the early days of the universe

the universe isn't ending anytime soon

[static loom]

just got off the phone with god, said he's turning it off next wednesday sorry

[north topaz]

the reason why I think that is that if there were such advanced lifeforms, they'd be leaving a lot of waste
we would notice since we've been observing the universe for so long

when humans discovered agriculture, there was now surplus food
and there would consequently be wasted food

and right now, we produce a lot of waste heat from all the air conditioners, cars, factories, and so on
heat is created as a byproduct of more useful stuff we are doing

if our universe is so pristine, that means no one has had the ability to affect it yet

who knows why

I'm not implying I believe in any sort of great filter

or that I know why

[gritty crater]

Maybe they live in another galaxy that is far away because a planet that has suitable conditions like Earth is very rare. Maybe one in a billion year

[north topaz]

yeah so there could be some microbe sitting on a random planet

that's 100% plausible

[gritty crater]

It is sad that with the current law of physics, we will never be able to create a spaceship that is fast enough to travel from galaxy to galaxy so we will never know

[north topaz]

some things are unknowable unfortunately

but hey life would be pretty boring if we knew everything

[gritty crater]

But maybe we can count on super-ultra telescope 💀

[long pumice]

a seriously useful accuracy space telescope would allow to have an accurate map of planet level things and chemical signature details of many closer planets, that would be huge knowledge upgrade about our planet's place in the Universe

talking over high quality detailed maps is much richer and needed guessing would narrow down

a number of complementary telescopes seem needed, the biggest one would slowly insist on the most interesting solar systems found and positionally mapped by smaller mapping telescopes

I suspect that JWST is hugely misleading on relative prices

JWST had huge delays, all that top science time added up to the cost also only by spent time. It produced only one piece, no economy of scale, also with likely lack of care about production efficiency while most of the cost was hard research cost.

but the somewhat comparable Apollo program had a cost equivalent of 300 billion 2023 dollars

interesting to imagine how to make an economy for things like these while the public interest is likely very high

it is more on the line of city infrastructure building (castles & co) relating to historical common economy, people would generally like to pay good taxes for something so important about our place in the galaxy, it involves more economy, some part of this economy gets circular to some degree, I suspect that it should not be done egyptian pyramid building economy style but a better living economy way

all that research and high tech involvement tends to propagate road infrastructure style positive effects over the rest of the economy, like education roads effects; done properly could be counted as really a net profitable factor in the overall economy, far from just a pharaoh tomb pyramid lasting stable monument value that could feel like 90% relatively buried time, effort and resources

I have this idea I'm going to try, I'm just curious if anyone has tried something comparable and what results they have yielded.

I'm considering making an SQL database in which every record is some sort of item that I have learnt with fields being date (why later), context/title (required), summary (required), data/proof (required), references (optional, such as peer reviewed studies) and finally, confidence (to be filled when I learn more in the way of probability and actuary science), while also utilizing the idea behind "spaced learning" to send me reminders. Might also include an "origin" field and see if I can find trends on how the origin/prompt that has me learn the content could impact how much I learn 🤔 (such as learning due to curiosity, a need, etc). Could provide some additional level of reinforcement and encouragement to keep learning perhaps after seeing it constantly build, who knows?

Anyone tried the above, or something similar?

[jolly path]

im not sure if an SQL-style database would be the best approach, perhaps something graph-based like obsidian might suit you better. for spaced learning, anki flashcards would be good

[gritty sable]

I'm only going to be managing it using rudimentary Python + SQL Injection

[jolly path]

i think you could definitely give it a shot, in my experience using tables to manage this type of knowledge hasn't been the greatest (i was specifically looking at biology papers/stuff in biology) - i thought that i was spending too much time filling in random minor things that i wouldn't refer to again, so i'm not a huge fan of table-based storage for thoughts

[gritty sable]

The perspective I generally like to adopt, is I like to understand things rather than just memorize them, it's why the proof or (data where the information was interpreted from) is a requirement. I really haven't been referring to proof and the origins as much as I'd like to, so I'm hoping by developing this habit, that changes 🤔

Proof could be a link to a YouTube video, a series of equations/axioms and literal raw data with fields to store and retrieve from via Python

Send me a message in maybe a month's time and I'll let you know how it goes if you like 😆

seems like a terrible use case for a relational database

maybe you can make it work but if you care about learning, know that you are learning absolutely dreadful database design lmao

[limber thunder]

you can literally query an obsidian folder with https://blacksmithgu.github.io/obsidian-dataview/

I use it myself but haven't found a real need to make metadata-intensive notes like the ones suggested, I just manage things in folders and with internal links between things or to pdf documents

[jagged forge]

sql is great for everything actually
reads use case
nevermind

Pls help, i only got interested in studying 6 days ago and currently, in almost done with algebra 1 and im doing basic electrostatics in physics, im also doing graph theory, im at fleury algorithm atm, and btw im atudying everything in parallel. So my question is should i pick up set theory?? Im gonna start algeb 2 and algebraic gemoetry soon. Set* theory. Kinda wanna ping truffle sparkle keh but nvm. I believe shes quite smart so she can prob help me in this one : )

[wind zealot]

can someone teach me latex

[main elbow]

#latex-help

[vivid halo]

if you are starting from scratch I made a template the other day to help someone get started

download LaTeX (e.g. if you are on windows MikTeX and TeXworks are good) and compile to get something like this

[vast wraith]

i'm sorry nG but i'm judging that charter text + latin modern math combination

charter is lovely but it needs a heavier math font

[true zinc]

LATEX CAN MAKE TABLES??? HOLY-

OMG

[vivid halo]

it's fine

I like charter because it's better than computer modern without looking too different

and I like the default mathmode text

I don't like the packages that are like

"here is our fucked up interpretation of \mathcal"

[vast wraith]

pain

fontspec is very useful and lets you handpick which symbols you want from different fonts

i have spent way too much time fiddling with the fine details with that.... i wonder how much math i could've done during that time

Hi everyone, anyone has university access?
I need this book PDF but I can't get it as my university is not listed :p
https://epubs.siam.org/doi/10.1137/1008032

[rose atlas]

I won't send it here due to the server rule

We cannot allow posting links or files with pirated content.
but I could obtain its .djvu file from some pirated library (Library Genesis Plus).
I can send via DM (msg me first), instead.
You can then obtain its .pdf via conversion tools such as https://djvu2pdf.com/ (which makes it grow from approx. 2 MiB to over 16 MiB).

[zealous garden]

2011 Civic you said

it's probably a 4 cylinder

I don't actually know if they make V6 civics

[jagged forge]

i see

[solar hawk]

Suremark you didn’t call me???

Wow

[jagged forge]

what

[solar hawk]

Nothing

I just wanted a reason to be cranky

[jagged forge]

I just wanted a reason to be crank
ftfy

[solar hawk]

What’s ftfy

[jagged forge]

fixed that for you

[solar hawk]

Hi wraith

[solar hawk]

I’ll fix your goddamn kneecaps and eyeballs for you

Sorry reflex

[jagged forge]

the opencry self react already made it less funny

why did u have to go and do that

[solar hawk]

Wow

[solar hawk]

There I fixed it

I just put it there so

It didn’t come off as threatening

So that I could have you feeling safe

And un suspicious

[jagged forge]

breh just commit to the bit

[solar hawk]

Wdym

[zealous garden]

Which of these two motors is yours

[solar hawk]

Don’t you get it suremark that IS committing to the bit

[jagged forge]

i actually have no clue, can't remember the last time i opened my hood

[zealous garden]

Kek

[jagged forge]

it's been years

feels like the 2nd one

but idk

[zealous garden]

Anyways, Hondas can be really fast

[solar hawk]

Yay

[zealous garden]

You just have to do things to them usually

[solar hawk]

Oh

[zealous garden]

Like there's the Civic Type R, or the NSX, or TLX Type S

Which have like each have 350+ hp

The Civic is a sports car with a turbo charged 4 cylinder, the NSX is a supercar with a V6 and hybrid motor, the TLX Type S has a twin turbo V6

But if you get a "lame" car like... a Honda Odyssey or a Honda Pilot, those V6s only make like low 200s power?

You can turbo charge them to like 600 horsepower without needing to change internals

Honda/Acura have a huge aftermarket platform and fan base that can help you get more power if that's what you want

[solar hawk]

Suremakr did you ever eat puffed rice

[zealous garden]

I know a guy with a bitching CR-X, it's a manual and has the weight reduction going on (AKA no interior in the rear)

Homie has to put in a cheat code to get it to start

https://tenor.com/view/honda-crx-civic-retro-gif-21590778

[jagged forge]

wild

[zealous garden]

But he's built it to 200 horsepower, which is a lot for such a small car

And impressive for a 2.0L naturally aspirated engine

[solar hawk]

Suremark why did you laugh at what I said

[zealous garden]

You know who makes a fast car though?

[solar hawk]

Uhhhhh

Maybe an airplane company

[zealous garden]

You mean BMW? Or Mitsubishi?

[solar hawk]

No like a boing 747

[zealous garden]

Lmfao

[solar hawk]

Boeing ig

[zealous garden]

So the name I was going to put here is "Hyundai"

Hyundai has some surprisingly nice cars out there that basically no one talks about

Like the Genesis G80 Sedan, the Hyundai Genesis Coupe, the Kia Stinger GT, the fucking Kia K9 and especially the Hyundai Equus

All underrated af

The 3.8L Lambda V6 in the Genesis has one version. I think the G6DKS, makes almost 380hp

The Equus has a 5.0L V8 pushing 420

To the rear

Not mind melting numbers

But

The Kia K9, with its V8, looks just like a fucking optima

Some BMW engineers have jumped ship to Hyundai in recent years

Hidden gems from the Korean Mitsubishi clone

[livid escarp]

Hey guys! Wasn’t sure whereabouts to message so I figured I’d send something in here, but I’m currently a comp sci/applied math double major looking to transfer to another college as solely a math major. I have a bunch of random q’s/worries regarding my application and I’m not sure if anyone here could help but I thought it’d be worth a shot! (my dms are open as well)

yo chill

[gusty socket]

can you not be rude to other users please

anyways, how is everyone? i am going to play slay the spire and chill out for the rest of the night

[fresh comet]

a little anxious, but I'm okay

real. me too. I really need to chill for a bit. I think tomorrow will be a better day

my favorite calculus problems

[surreal sapphire]

so true...

[latent edge]

I agree that the Riemann hypothesis is my favorite calculus problem

[surreal sapphire]

its the most fitting

you can reformulate it as the evaluation of some real integral

[static loom]

youtube was a mistake

[surreal sapphire]

if academia doesnt work out i should become a math youtuber

[latent edge]

this is true yeah

[thick yacht]

Instead of an ML researcher?

[surreal sapphire]

i dont do anything with ML

i dont think this will change

[thick yacht]

That seems like it's become the default failure path for string theorists.

[surreal sapphire]

i think i have enough credentials to not have to do this

[thick yacht]

Credentials meaning you don't have to worry about the job market?

[surreal sapphire]

besides i think the market is too flooded by now anyway

[surreal sapphire]

i hope, but who knows

im 100% confident i can always find a job

but i only applied once and got the first job i ever applied to, so ...

What's the best app for flash cards

[ember lance]

Anki if you take the time to figure out how to use it

[solid yarrow]

though anki in itself is not really complicated to use

like for basic flashcards it's actually very similar to other apps

though you can also do fancy stuff like voice etc.

[violet meadow]

Yo can someone check math discussion chat I’m very curious as to what level of math I’m at

[north topaz]

just wanted to share my solution to 2017 AMC10B

I had to look up what a vertex of a hyperbola was, so that means you can choose say (1, 1) to be the centroid of the triangle
by symmetry across the line y = x, we must therefore have (p, q) and (q, p), and (-1, -1) as vertices, and hence p + q - 1 = 3 or p + q = 4

so p + 1/p = 4 implies p^2 - 2 + 1/p^2 = (p - 1/p)^2 = 12

since the line x + y = 4 makes an isosceles right triangle with the coordinate axes, the distance between (p, q) and (q, p) must be sqrt(12) * sqrt(2) = sqrt(24)

hence the squared area is (sqrt(3)/4 s^2)^2 = 3/16 * s^4 = 3/16 * 24 * 24 = 9/2 * 24 = 108
