[surreal sapphire]

-ach is also related to Bach meaning stream

the town is just named after the stream that flows through it

[uncut steppe]

Hi

[surreal sapphire]

but pretty much every european town (that was founded in the middle ages) is named after some landmark feature or other geographical information

[modest nacelle]

mine is named after a dam in the river

[surreal sapphire]

you also have places named after economic use, but in the middle ages this is usually related to some geographic feature anyway

[clever quail]

Guys can someone tell me how can I plot graph of a function using graph plotter

[merry plank]

Low quality bait

[icy heron]

I will tell you if you stop posting every question to 5 different channels

[fresh ermine]

What is a crank btw

[deep mango]

someone trying to do research math but doing it incorrectly and with no formal training, usually claiming they solved big unsolved problems

[fresh ermine]

Ah I thought it was just a person being an asshole

[brave flare]

we have a prime example going on on this server right now

#math-discussion message
check this guy

[fresh ermine]

Mathnerd99

That is quite the name

[old oak]

It pays to advertise

[old oak]

https://en.wikipedia.org/wiki/Mathematical_Cranks

[fresh ermine]

no im the product

[fresh ermine]

Ig I gotta experience more cranks to understand them

[old oak]

Well, you're in the right place to encounter them

[lost fjord]

we had a riemann hypothesis crank a while ago who was also convinced that someone here was gonna steal his $1m

[fresh ermine]

😭

Your kidding surely

[old oak]

Nope, that's very often their stated reasoning for not providing any details of their breakthrough

[old oak]

There's no bounty on Collatz so they tend to be more forthcoming, although even then they often express concern over someone else taking credit for their accomplishment

[lost fjord]

they also started deleting their messages on this discord server lmaoooo

[fresh ermine]

😭

[limber thunder]

istg these $1 million prizes have done more net harm than good to the public's view of mathematics and to mathematics practice

all it's done is attract dumb narcissists who know jack shit about math to public forums like this

as well as to math departments irl

I've met my share of cranks lol

[fresh ermine]

Not sure if they have a term similar to crank in comp sci..

[brave flare]

thus far i have (irl) been completely free of cranks

[fresh ermine]

how is it typically

[brave flare]

but thats probably because im at a university, would be weird if there were active cranks studying

[spiral solar]

vibe coding

[fresh ermine]

That’s it

[limber thunder]

script kiddie is another term, more from vintage hacker culture ig

not sure if it completely captures the delusions of grandeur a "crank" has though

I'd picture something like a non-technical startup techbro dude in founder mode

or elon lmao

[limber thunder]

real annoying

there was this one dude who managed to graduate undergrad claiming to have an elementary solution to poincaré's conjecture and RH or some crap

kept pestering profs and boasting to impressionable freshmen (hence why I'm inclined to say this whole thing has been net bad for academic culture)

and there was some other dude in my cohort who clearly had some kind of paranoid schizophrenia I was legit worried for them lol

but did my best to ignore them otherwise

[fresh ermine]

😔 I mean best leave them be

[fresh ermine]

Script kiddie as well yes but I think vibe coding is more crank like from your descriptions

[limber thunder]

my roommate is a sort of successful vibe coder lmao

not far off but still not 100% I think

at least he knows his stuff regarding backend tech and the gnu/linux ecosystem

but he uses agents in an absolutely ridiculous way

[fresh ermine]

I don’t have gripes with vibe coders tbh some are good it’s just they don’t get paid enough to care he writes shit code because middle management can’t tell the difference and the more he fixes the higher the pay

[limber thunder]

lol

[fresh ermine]

He’s a fucking genius

[limber thunder]

from the creators of vibe coding, vibe tech debt

[fresh ermine]

Not into ai that much so pray tell what an agent is

Is it just like a mod you install on the ai? To perform better like prompting

[limber thunder]

not really, it's a vague descriptor for an AI product that can perform tasks autonomously

[fresh ermine]

So automation for certain tasks? how’s that beneficial

[limber thunder]

so something like "here's this spec and here's my codebase, please implement features A, B and C and some tests"

[fresh ermine]

oh I see

Nvm

[limber thunder]

stuff such as https://docs.cursor.com/chat/agent

[fresh ermine]

I tend to avoid these things but I’m curious so

[limber thunder]

I don't use it since I don't really code for a living lol

[fresh ermine]

I mean what do you do

[limber thunder]

but I've been wanting to try out some new IDE for LaTeX and numerics stuff

rn I'm starting an applied math PhD

[fresh ermine]

very nice

https://manus.im/?index=1

interesting thing I found

[spiral solar]

manus

[fresh ermine]

They got replay demos of prompts

[lost fjord]

ngl i doubt that it's the $1m that's the main cause of cranks

like just look at the joe rogan podcast & terence howard

or like all ur anti-vaxxers

i mean overall, i think the millenium prize problems just mean you have the random crank in an obscure corner of the internet where most everyday ppl won't see them

especially cus it's a lot easier to be cranky about something like 0.999... != 1, which most ppl will have encountered at some point rather than

"i have a proof of BSD" which like no one in the general public will even understand lol

[limber thunder]

yes, even the concept itself predates the millenium prizes by years and maybe decades https://en.wikipedia.org/wiki/Crackpot_index

but $1m is a huge incentive

[lost fjord]

lmao i love this

[true wedge]

vim 🗿

[true zinc]

I always took "script kiddie" kinda literally, as in some petulant child who learned how to download Kali Linux or google scripts to do things and then just annoys people and boasts about their skill

[vocal vessel]

Hacked account.

[hardy iron]

When speaking about script kiddies, I often think about children who paste stuff into the browser’s console

[vocal vessel]

Isn't that exactly what they are?

[fresh ermine]

Can’t sleep but I’ll add to this.. typically when I think of skids (script kids) today it’s like flipper zeros and thinking they’re hackers

Or like watching one Kali Linux tutorial

That and ppl who cheat in video games

[limber thunder]

yeah this is kind of the point lol

it's how the term came to be

[burnt dune]

finally learnt about lie actions homogenous spaces and principal bundles

so easy and elegant. the only boring part was proving that if G is a lie group and H is a closed lie subgroup then G/H is indeed a smooth manifold. from then you can prove things are smooth much more easier now. k grassmnian is O(n)/O(k)xO(n-k), ETC

cool

[neat lintel]

who up integrating

i know i am

lots of pattern recognition

[vivid halo]

yess

[burnt dune]

bro it was so fundamental like ikd why they dont teach this in high school

[vivid halo]

have you learned about how this relates to characteristic classes?

[burnt dune]

SO(n) literally acts on S^n lmao obviously

[burnt dune]

no not yet! i barely defined them in chapter 5 in milnor and stasheff

lmao this is funny cuz

there was this basic problem to show that the grassman manifold is a smooth manifold

u can do it easily by just looking at the chart milnor gives and ccomputing things locally

[vivid halo]

Chern classes come from the classifying spaces BU(n) for the unitary group U(n)

[burnt dune]

but its boring and painful. i learnt this just to be able to do this problem in 1 line

[burnt dune]

yeah im still at the beginning where i proved that any bundle admits a map int othe infinite grassmanian

and the characteristic class is the cohomology class induced by this map to the base-space

[vivid halo]

BASED okay yeah you get the picture

[burnt dune]

yeah and now it motivates me to

[vivid halo]

complex oriented cohomology theories soon

[burnt dune]

learn how to compute the cohomology ring of the graassmnian. so the next chapter tries to build a CW complex for the grassmnmian and then (probably?) computes it using cellualr cohomology

but then i saw this problem of proving that the grassmnian is smooth and i was like.. yeah

[vivid halo]

yeah sometimes the Grassmannian models are annoying to work with and it's nice to have some other ways of working with these classifying spaces

[burnt dune]

yeah i mean doing things in coordinates is always boring and painful

even with the simplest cases

the fact that u can just say Gr_k(R^n) is just O(n)/.. is so cool honestly

cuz there si a principal bundle O(n) --> V_k --> G_k

O(n) acts transitively on V_k

[vivid halo]

crazy how the orthogonal group do that

[burnt dune]

yeah bro once one looks at pi_n and draws these things it gets voodoo quick

like that famous table with the bott-periodicity one

for pi_k(S^n)

these patterns are just

too in-human

[vivid halo]

well yeah in general the homotopy groups of spheres are like, absurdly complicated

[burnt dune]

yeah

the fact that there are these patterns just makes it much mroe hype

and scary

[vivid halo]

you can say a bit about them using the J-homomorphism J:O->S*

this guy

[burnt dune]

yeah this was in hatcher

[vivid halo]

one has very good control over the image

but yeah this only gives you information up to height 1

[burnt dune]

yeah

cool magic bro

also u might know htis

do i need know about srs homotopy theory to learn about spectral sequences

[vivid halo]

not really

[burnt dune]

i have been told that ih ave to learn them asap

[vivid halo]

most machinery around spectral sequences is homological algebra

they are incredibly useful yes

[burnt dune]

cuz alot of the homology theories that i might learn use them extensively (khovanov lee stuff)

[vivid halo]

yeah it's kind of hard to do many computations in homological algebra without spectral sequences

[burnt dune]

i see

is hatcher chap5 the standard reference for someone who wants to do it for topology

or is there a better one

[vivid halo]

look at the relevant chapter of Weibel's homological algebra

[burnt dune]

okay

tysm

[vivid halo]

Hatcher does a decent job too but it's good to get this from a textbook specifically about homological algebra

[burnt dune]

i see

[vivid halo]

just focus on learning how the spectral sequence for a filtered complex works that is good enough for most applications and it's the easiest to motivate

[burnt dune]

damn its sub 100 pages

thats cool

[vivid halo]

the motivation is just like, the main trick of homological algebra is to turn short exact sequences into long exact sequences in cohomology

but what if you have a filtration? Well you can break this up into a bunch of short exact sequences stacked together

how do the associated long exact sequences stack together then? This is what spectral sequences organize

[burnt dune]

yeah thats what iread about in an article called you could have invented spectral sequences

[vivid halo]

yeah great article

[burnt dune]

its like telling u if you have a chain complex where things factor out as direct sums u could have like just computed homology there and then direct summed everything

and then it tells u that doesnt happen but filtrations happen more often

oh u read it

[vivid halo]

yeah

[burnt dune]

alot of hype around it tho and alot of ppl say its hard so

[vivid halo]

but yeah in practice the hard part is computing the differentials in the spectral sequence

but half the time you will be in some situation where like

the spectral sequence instantly degenerates or it degenerates after a page or so without having to worry about unwinding all the definitions for differentials

[burnt dune]

i see

[burnt dune]

brings me back to hs days where u would hope the integration by parts doesn't go long forever

same vibe

hes a mod bro

[vivid halo]

lol I am not

[burnt dune]

or was?

[vivid halo]

but also this is quite the reaction to a react

nothing more than like "hmm puzzling" it's not an insult

no lol

mostly just like "what was the train of thought that gave rise to this question"

okay

you seem to be looking for an excuse to pick a fight and be offended

not sure I can do much about this

[burnt dune]

im telling u guys

the pics coming from low-dim topology are just

insane

[vivid halo]

I still crave an "accurate" picture of this knots and primes analogy

one can only draw cartoons

[burnt dune]

oh i think this is more

srs geomtry/AG

[old oak]

Depends how low you get; since zero-dimensional topology is just the Cantor set.

[burnt dune]

the cantor set has a pretty cool pic

[old oak]

An excellent set to be sure, but I'm not sure you can get many fancy graphs out of it.

[burnt dune]

just the construction one isn't that bad

given that is the lowest on the food chaiin

haha

[vivid halo]

[neat lintel]

Is the infinity strait or curved

Can we see in 3d?

Is the univers expanding

WHats a gravastar

Is it possible to travel in speed of light

Can you bend the time of the univers

can you slow someone down travelig in an infinity speed

how hot can something be

[brave flare]

what

what are these questions

ok in order of your questions

[unborn meteor]

,w planck temperature

[neat lintel]

They are the mystery of the world....

no
yes
no
its weird

[neat lintel]

Can we see in 3d?

[brave flare]

yes

we have 2 eyes, granting us depth perception

[unborn meteor]

,w sqrt(c^2*h/G/k^2)

[unborn meteor]

some people can't

[neat lintel]

THink about it, if you got a cube that got nothing on it and the same light, traveling away from you and at the same time expanding, you wont see thats its moving away from you

And you wont see the depth

[runic elk]

I know this may be a dumb question , but is physics very related to software engineering?

[unborn meteor]

it's abour 1.416e32 K

[unborn meteor]

everything is related to everything to some extent

[brave flare]

good thing this doesnt happen

[runic elk]

I really hate physics

[jagged forge]

hi chat

[neat lintel]

Sometimes it does

A black hoel....

[unborn meteor]

no...

[runic elk]

I thought software engineering was probably the one who had the least amount of physics to it

[brave flare]

what

[unborn meteor]

nothing with positive mass can travel at or higher than the speed of light

[runic elk]

So...there isn't any future for somebody like who loves math and hates physics

No major

[unborn meteor]

no there is

lol

many people here do that

[runic elk]

Hmm

Well it's probably something minor

Convince me

[neat lintel]

Negative mass always travel faster that light and there for we cant see that, like a model with inverted faces

(If you know modeling)

[brave flare]

negative mass
what?

[unborn meteor]

yes i believe this is true

however it is unknown whether negative mass can exist in our universe

black holes do not have negative mass

[runic elk]

@unborn meteor what are these majors like?

[unborn meteor]

i'm a high schooler

go ask someone else

[runic elk]

Same here

[neat lintel]

We need to do vacum basiccly infinity empty

[unborn meteor]

why?

[runic elk]

Do you know of anyone ?

[unborn meteor]

we already have that

[neat lintel]

Nvm

[unborn meteor]

no

[runic elk]

Hmm

This will be hard

[unborn meteor]

ask in a different channel lol

[runic elk]

I tried in discussion 1

[grizzled crypt]

econ? compsci? pure math? lots of paths use math but no physics

[unborn meteor]

nothing can travel at infinite speed

[runic elk]

Do they lead to good majors ?

[neat lintel]

Hmmmmmm

[runic elk]

Yeah pure math for example

[unborn meteor]

wdym

[runic elk]

Idk about econ , compsci

[neat lintel]

Can you bend the time in the unverse, like to black holes bend the time around then to go slower?

[unborn meteor]

yes

time dilation exists

[brave flare]

yes objects with mass bend spacetime

even you

[unborn meteor]

you make everything else move faster than the black hole

this will make it slow down from your perspective

[neat lintel]

But can you bend this plate so it will to a 180 turn and go under itself?, like a 90 degrees rotated "U"

[unborn meteor]

no one knows

it might be possible

or it might not

[neat lintel]

Then we can timetravel

[unborn meteor]

no

wormholes are not time travel

it is impossible for humans in our current form to time travel

[neat lintel]

but if we did as I said, and then made a tunnel between the 2 sides

[unborn meteor]

yeah

that's not time travel

[neat lintel]

But is negative mass mass that travel backwards in time?

[unborn meteor]

it's kind of like increasing the speed of light in that place only

[neat lintel]

(Just an idea=

<True

[unborn meteor]

if i remember correctly yes, that's one of the problems with making wormholes

[neat lintel]

Yeah

[unborn meteor]

any more questions?

[neat lintel]

Will the univers shink down again?

Like shrink to a small small ball and have big bang again?

[old oak]

Well, whatever it does, we won't be there to see it

Unless it's scheduled for next week and I just missed the memo as usual

[unborn meteor]

we think it probably won't

but it might

[neat lintel]

Haha

Yeah

Now its time for me to practise francais

au revoir

Why

Je suis un fatigue et il est neuf heures

Oh no, Au Voleur!

[wild lantern]

Why not just block them?

[neat lintel]

YEah, cya later

[wild lantern]

It seems you two don't get along.

[brave flare]

blocking ng is a crime actually

[wild lantern]

Surely you see there is no point in silly little image reactions causing so much trouble between you two.

They can't react to your posts if you block iirc

[vivid halo]

mama mia

[wild lantern]

I feel like it is equally unfair for you to single them out and I think there is a pov where you singling them out like this can be considered bullying too.

What I want is a solution in which ya'll aren't pissing each other off and making things toxic here

I'm telling you what I want.

I think you jumping to the assumption that I mean this in bad faith is pretty unfair.

[vivid halo]

you are tilting at windmills

[wild lantern]

Lets not make this worse

Is the solution here for both of ya'll to block each other?

People can disagree, dislike each other whatever. It happens. I'm sure you guys have whatever reasons you have. I just want to avoid toxicity here. What plan gets us to that?

Reposting the same thing is not helpful.

Ng has a right to disagree with you. This is a public space and the things you post can be criticized within reason.

The first and last two are not so serious.

Last one is vaguely shitty. Idk which react that one even is?

[old oak]

I like how you discovered the word filter but didn't pause to wonder why it's there

[wild lantern]

Eh, I get why they are evading it here.

Okay, so why don't you just block them then? You're not gonna magically start being best friends or getting along?

Don't tell me what to do.

I'm asking you to help me figure out a reasonable solution.

Small reactions are not this serious.

No I'm not. You're making a lot of claims about what I said that are definitely not things I said.

I saw the previous dms as well.

Okay, in the real world, adults tend to not interact with people they know they have problems with.

Adults also tend not to make small issues that waste many peoples time over relatively innocuous things.

Okay, we are not in school.

Okay, this isn't a university?

I think some of your behavior counts as bullying and threatening.

I don't appreciate that.

You need to be reasonable.

I'm giving you a chance to do that.

[old oak]

School of hard knocks

[wild lantern]

The idea here that we should just silence ng because they might react to your posts in ways you dislike is just stupid.

[gusty socket]

if you block someone, they cannot react to your posts, by the way.

[gusty socket]

@onyx holly i think this is a solution that you might be happy with.

[wild lantern]

Okay, @vivid halo I would appreciate you no longer interacting with this user. Would you be willing to block them?

And you likewise?

[vivid halo]

way ahead of you on this one

[wild lantern]

Okay, so then block? Obviously nothing good comes from you two interacting.

No, I think you should also block.

[gusty socket]

you have to block him for that, is what I'm saying. if you right-click their name you can do that.

also please stop evading the automod filter

[wild lantern]

Yep

But if you block he can't

[gusty socket]

if you block him then he will not be able to. that's why i am proposing that you take this course of action.

[wild lantern]

Yeah, it shows as a blocked message but you have to manually open it.

You can't react to ppl who have you blocked though.

If nothing else this is the sanest next step.

[vivid halo]

I literally do not care

[wild lantern]

Not buying what?

I can block you to show you how it works? Lmao

[gusty socket]

no one is trying to pin anything on you. we are just recommending that you block him so that it makes it harder for him to react to your posts with things that you don't like

[vivid halo]

then just block me and leave it at that instead of making a federal case out of it

[wild lantern]

At some point this does become a you thing.

At what point are you targetting and harassing ng?

Has ng ever threatened you?

You've threatened them.

Seems kinda shitty to sit here and act like you're the victim while simultaneously threatening people.

Yeah, I'm tired of this lmao. You're no longer welcome here. Cya

[vivid halo]

yeah that's one solution

[limber thunder]

I'm not seeing how someone adding a reaction to your question because they find it amusing or silly or whatever warrants this sort of reaction

[vivid halo]

hell hath no fury holy moly

[old oak]

Such a promising career so prematurely ended

[limber thunder]

welp that settles it ig

[wild lantern]

Fuck

Like, how hard is it to just block? Christ.

[limber thunder]

nooo you don't understand the server staff must side with ME and prove me RIGHT

mods please ban well known TROLL ngroupoid

[old oak]

I'm so glad I started reading the mathcord again today

[forest jackal]

Yeah this was entertaining as a bedtime read

[old oak]

I mean, my condolences to all the mods whose time was wasted by this

[jagged forge]

meltdown over a single :hmm: react…

[old oak]

But in the abstract it was quite entertaining

[brave flare]

and a sully

to be fair

[limber thunder]

nah I'm with gomez on this one

kudos to smay and doot for actually doing their job as mods

[flint basin]

The mathcord sully gang claims another victim...

[jagged forge]

o the oppression

[sharp mulch]

What promising career....

[old oak]

I was not being entirely sincere

[gusty socket]

I'm surprised it's so late for you. Hope you have a good sleep!

[forest jackal]

Europe. Won't sleep for a while still, have some things to read but got distracted by the drama haha.

[vast wraith]

damn i missed it

[fresh comet]

[hollow ginkgo]

[inner canopy]

same tbh

[main fable]

Three years ago I came onto this server asking for help to estimate how much money was in a large jar, and I got my thread shut down saying it wasn’t the “math we do here”. I’m still salty about it because I think it’s literally math, idc that u think it’s some weird kind of math, it was estimations which is MATH. I think the moderator shut it down bc I said if I got the closest number to the real amount I’d get a donut. I’m still salty cuz I don’t think it was fair. I wanted to tell somebody

[sharp mulch]

Ok

[fresh ermine]

Did you ever get the money

[main fable]

No I didn’t get the donut and the amount was like $400

[fresh ermine]

Damn..

truly a bad day huh

[main fable]

Yeah it was literally math who would shut down the thread. I think the moderator just didn’t want me to succeed in life

[versed fiber]

it's Pi Day !

[eager minnow]

you mean pi/2 day!

[sharp mulch]

Do you want to try again

[true zinc]

Servers change over the course of time, if someone was an asshole to you back then, the chance that the same person may treat you the same way, let alone still be here is reduced. The probability is nonzero, that said person is still around and would treat you the same. Now instead of malding, get over it and continue doing maths.

[eager minnow]

360° are pi radians!

[summer badger]

Hi guys, been using this fuckass textbook for physics called “fundamentals of physics” by Halliday. Can anyone recommend a good physics textbook for first year uni students that goes very in depth, with a good range of exercises and rigorous proofs?

[main fable]

Omg I wasn’t even mad I just wanted to tell somebody a funny experience that happened 3 years ago!!!!!!!!!!!!!!!!!!!!!¡¡¡

Salty. That’s it. Have u ever heard of those stories that people tell that are like “what’s a grudge you still hold after a long time?”

Yeah! Was just sharing a fun little cute story!

So I think I’ll continue telling funny stories from the past AND doing maths!!! Yay!! How fun

[hasty silo]

ur so real i understand this so much you tell your silly stories pal

[main fable]

For real.

[true zinc]

You explicitly said "I'm still salty cuz I don't think it was fair"

I this directly implies that you're still holding a grudge

[main fable]

Yeah I do hold a grudge! Sometimes people just hold small little grudges against something that happened a long time ago. Doesn’t mean it keeps them up at night, just a funny little memory, you know?

To be salty is to be upset over something “little”.. so yeah, I explicitly said I hold a grudge over something little. Nice!

I just don’t think it’s that serious. Like it’s not a bad thing that I hold a funny little grudge and it’s not like I’m calculating the probabilities that this is going to happen to me again because I am tweaking out at the thought of it.

So I just don’t understand ur initial comment. It just gives me the impression that I’m not allowed to reminisce about the past and funny little grudges that I hold, and that I should “move on” 🤓🤓. Like it’s not that serious. I think it’s fun to talk about funny little uptight people on math servers that you interacted with years ago!

Yay!

[sonic ether]

What am I reading

[barren anchor]

that nonsense was super uncalled for don't worry about it

I do think there's an aspect to discretion which can suffer in an atmosphere of continuous rigor

so like this server holds many good examples of people who are probably chill but don't code-switch with perfect appropriateness

[main fable]

LMFAO

[main fable]

Ok fine

I get it

[barren anchor]

I had a phone interview this evening and it's possible I came here just to get more rigorous discourse

like cause I know I'll find it here

I love to feel the pressure to be accurate

am I terrible for the social vibe? probably

or perhaps I will bump into another and we will unite in a perfectly rigid discourse

[main fable]

Yes your texting seems pretty professional

[barren anchor]

do it tho

[main fable]

Maybe I just don’t understand the vibe of this server

[barren anchor]

it is best used as a tool to answer technical questions and everything else is wildcard who even knows what ur gonna get

[main fable]

Yes I suppose I just figured Discussion would be casual and chill

[barren anchor]

It can be. #chill is underutilized imo but it supposed to be that

this is supposed to be casual, but it's also host to a lot of debates which are undertaken with the aim of actually being correct or establishing something

[main fable]

Okay well I’m still open to debating whether or not I should move on from a funny memory years ago and not talk about it

😈😈

[barren anchor]

it's a good debate. the inner debate is interesting, I'd be annoyed if that got shut down because like, I think that kind of math is the kind done here. Perhaps more appropriate in preal-and-algebra but it's still within the domain

it's a little young and all but imo it's jerkish to turn off somebody asking basic math questions

I don't think that would happen now

[main fable]

Yeah I think they just assumed I was like fooling around or something? Cuz it wasn’t anything explicitly you write down maybe

[barren anchor]

helping people formulate is one of the many things this server should do

[main fable]

Let me try to find the picture

Oh I can’t send pics here

[barren anchor]

I mean I get it, it's cookies in a jar. Presumably you get the volume of a cookie and the volume of the jar

[main fable]

No it was money

Coins

[barren anchor]

oh then coins

hohoh my bad

[main fable]

And I needed to guess how much money was in it

[barren anchor]

I'm hungry

[main fable]

Yeah it was honestly a lot of money

In a smallish jar

I guessed $80 and it ended up being $400 or even more

[barren anchor]

yeah if you still care to explore the problem you can. I'd just average the volume of a coin and then the volume of the jar, maybe put a fudge factor in there for airspace and say it's 75% coin 25% air

[main fable]

Mmm yeah

It was a mixture of coins

[barren anchor]

like V(jar) / V(coin) * .75

[main fable]

25 cents 5 cents 10 cents

$2

$1

[barren anchor]

ohhh way more interesting

[main fable]

Yeah it would probably be really hard to estimate it

Maybe like

Today if I had to

[barren anchor]

it'd be pretty easy to just average the value of any amount of space though

[main fable]

I would make try to count how much was in a fingers length

And then just multiply that amount by how many finger lengths there are

Idk

[barren anchor]

I think you could alternatively make a conversion factor for each into value / cm^3, and then average across them by ratio. So you've got some one average value / cm^3.

you'd need to know the distribution though

[main fable]

Ohhhhh

[barren anchor]

like 10% dollars 10 % nickels etc

then you could say each cm^3 has some average value

[main fable]

Like if there’s 4 nickles 5 dimes and 9 quarters just average all those amounts together and then use that

[barren anchor]

yeah. So you'd take each one's value / cm^3, average them all together, and then divide the total volume by that.

[main fable]

Could u do that with just a picture

[barren anchor]

can you see the top layer of coins?

[main fable]

I think it was like a side view

[barren anchor]

could assume that the distribution is the same throughout as whatever it is in the view you have

if they're assorted randomly in the jar then it's a good bet

[main fable]

Yeah

Wow

I’ll keep all of this in mind when the opportunity arises again

They won’t see me coming

[barren anchor]

lol and you'll run off with all the coin

[main fable]

Yeah

Get myself 150 donuts instead

[barren anchor]

if they give you the option, shake the jar first

try to randomize the view you have, so it's a good representation of any slice of the coins

shake the hell out of it and demand they acknowledge you're just doing math over there

[main fable]

Hahahaha

What country r u from

[barren anchor]

I hail from america

[main fable]

Oh really

I might be American soon

[barren anchor]

hale?

it's a decent status

[main fable]

I think ur president wants me

Or us

All of us

Oh no

[barren anchor]

does he? he's so focused on who's here now

veterans and old people and stuff like that

[main fable]

Yes he wants us so bad

Canada

[barren anchor]

oh yeah he does think canada should just merge

[main fable]

Facts

But then it would be kinda hard for a republican to win again

Unless we didn’t get voting rights

Cuz there aren’t many republicans in Canada

[barren anchor]

yeah he probably won't do it then

but it's kind of a cool thing to say

like that's so big

there's not a lot of country mergers in the western world these days

musk will advocate making the Moon the 52nd state and that'll be even bigger and hit hard enough to keep us steady until the apocalypse

[scarlet ingot]

I recently graduated with an MS in Math (last December). I emailed one of the professors, but they usually seem busy.

@vivid halo Here's the representation im thinking about.
Write z = Re(z) + Im_i(z)i + Im_j(z)j + Im_k(z)k to denote a quaternion. Write Norm(z) = z•\bar(z)
We have 5 real valued functions Norm, Re, Im_i, Im_j, Im_k : H -> R. We can multiply them pointwise to generate a real polynomial algebra (which will be a real subalgebra of the continuous functions H-> R) . Note that Norm is the sum of squares of the other functions, so this is isomorphic to a polynomial ring in four variables, with real coefficients .

Let k be a fixed positive integer.
Consider the real vector space V_k spanned by the functions Norm^l • Re^r • Im_i^s • Im_j^t • Im_k^u where l, r, s, t, u are nonnegative integers such that l+r+s+t+u <= k. I claim that V_k is a right representation of G = GL_2(H) given by f(z) \mapsto Norm(cz+d)^k • f((az+b)/(cz+d)).
I believe I've checked V_k is G-invariant, unless im making a fatal mistake...
It's by definition a finite dimensional real representation.
Is it irreducible? What is its dimension?

[vivid halo]

well how much do you understand about representations of Spin groups?

I would first try to understand what is happening with SL_2(H) where you can use these facts about Spin representations, in this case for Spin(5,1)

[bronze pelican]

Nothing

There are 2 complex linear irreducible representations of Spin(5,1), each of complex dimension 4

So essentially, they are two irreducible representations on H^2 , right?

[vivid halo]

yes

Hey there, Im not sure if this is an appropriate question in this channel but I wanted to ask most mathematicians here. What do you guys write down on paper when solving a question? Its very silly but I want to know that if your given a problem to solve then how do you try to solve it? Do you all do mental math in your head because it comes naturally to you? or do you guys actually write stuff down to solve it? If its the latter part then what do you write down or how do you start in order to understand the question and solve it? I usually just enter the formula and call it a day but this gives me a disadvantage when solving more complex questions that only geniuses in my class solve. I wanna know how you guys do hard and complex questions like these? (Im sorry if you don't understand this, I only started learning English a year ago so Im not fluent in it)

[neat herald]

What's the highest level of math you're comfortable with/what topics are you familiar with?

[main elbow]

ill give a half answer to this question, obv is very helpful to write things down and have good presentation etc etc for exams
but dont neglect the ability to think about math and to have some mental image, some intuition rather than just symbols on a page
its a great exercise of working memory and also lets you approach harder problems by thinking about them throughout the day when say youre walking around town not at your desk

[valid spear]

grade 10 maths, like were at sinus and cosinus, i'm ok in triangles but i'm slow asf in solving stuff, my brain is slow in general

[craggy obsidian]

idk what channel this would go in but if i had two functions f(x) and g(x) and f(x) grows asymptotically faster than g(x), is f(g(x)) vs g(f(x)) faster growing or do you need more info?

[main elbow]

need more info
f(g(x)) ~ g(f(x)) ||x^3 grows asymptotically faster than x^2 and (x^3)^2 = (x^2)^3 = x^6||
g(f(x)) = o( f(g(x)) ) ||e^x grows asymptotically faster than than x^2 and e^(x^2) grows asymptotically faster than e^(2x)||
f(g(x)) = o( g(f(x)) ) ||x^2 grows asymptotically faster than e^(-x) and e^(-2x) grows asymptotically faster than e^(-x^2)||

[craggy obsidian]

how about increasing functions

this is really unintuitive to me cause i wouldve thought the growth rate is all the matters

[main elbow]

the first two example are both with increasing functions so its still not enough to tell

there may be an increaseing function that would be an example for the third case idk

[craggy obsidian]

i think n! and 2^n works

but like they grow kind of similar

i wonder if one function can grow so much faster than the ot her that you can say

idk how to formally write it thoguh

Why We Derive.

[VERSE 1]
Let’s look at the function, f of x,
Taking the derivative is what is next.
Using power rule for the exponents,
The product and the quotient for two and more components
Maybe you could use the chain if that’s the way,
Maybe multiple rules needed if that’s what you say,
Sometimes it could just be memorizing the identities
Trig and logarithmic and so more may just be what’s the key.

[PRE-CHORUS]
And if you ever ask why we derive though,
It’s the speed of the function, for that’s what we strive for,
And if you ever ask, how to apply it,
Start with the point slope, that’s why you derive it!!!

[CHORUS]
Velocity… acceleration….
The min and max… of the function…
To higher maths, it is a station…
Continue on… to the Calc nation!!!
Why we derive, so to arrive,
That we survive, Calculus time,
Oh should we stay for, deriving way more,
And Calc is honest, struggle’s a promise!

[VERSE 2]
Understanding what each formula states,
Is important for the memory and for your fate.
Bringing back the formulas, we can stake,
That half of them are simple and other are a piece of cake
Plug in the numbers, for powers and the others,
Crackin’ the numbers, for product and the brothers,
Putting the functions, and using the chain rule,
Checking that you do it right, making use of all the tools.

{GO TO PRE-CHORUS AND CHORUS}

[BRIDGE]
F x, f prime, why we, derive
Find the, tangent, instant, stagnant.
(X4) and back to CHORUS

@icy heron i know you mentioned vector spaces earlier, did you happen to take any advanced linear algebra, or go through any advanced linear algebra books on your own?

[icy heron]

I have taken two linear algebra classes, not exactly advanced, but covering most of the stuff in Linear Algebra Done Right for example

[astral bay]

oh that's awesome, i am taking a course that uses LADR as the book

[astral bay]

formal uni course

[astral bay]

anyway, the reason i asked was. i was curious what parallels/analogies/similarities you saw between linear and abstract

[icy heron]

I think in some sense you could think of linear algebra as a subset of abstract algebra. In abstract algebra you learn about generalizations of vector spaces (modules over a ring, a vector space is a module over a field), and you learn about the structures a vector space is built out of - (abelian) groups, rings, fields, etc.

[astral bay]

cool, helping that this course helps me out when i take the abstract algebra course

[alpine kindle]

i mean
a vector space is an algebraic structure

[icy heron]

yes, but it has algebraic structures inside it too

[old oak]

Y'all uhhhh
I have a request for help but that's a little different?

Basically I am making this gift for my girlfriend and it's a little wooden heart
And I want to inscribe it with our anniversary date
I thought about just writing the date In there, however
1- the heart is quite small and hard to write on
And 2- it's a bit too basic to just write the date itself I think

So I googled a bit and tried to find a way to encrypt a number in a way that's more fun and unique
However I haven't really been able to find a good encryption for this one
I also looked at different numerical systems in historical order but they weren't great either

I am hoping somebody here knows a good way to encrypt a 6- digit number ?
Idk

I also thought about hiding it with math but the 3 numbers don't have common divisors in between all 3 so...

It'd be a bit difficult

( the date is 30/10/24)

[uneven steppe]

Is she into math?

Has anyone here gotten a job after studying mathematics?

[surreal sapphire]

uhh

I was wondering if it's a realistic goal to achieve, where you can get some sort of job after let's say mastering calculus...

maybe tutoring?

@surreal sapphire official uni degree and all?

[surreal sapphire]

sure

i did not master calculus though

[fathom hamlet]

I don't know if this question is appropriate for you, but do you think in your opinion, that a person can get a job by mastering calculus? For example completing the calculus book by Gilbert Strang from MIT.

no degree though

just knowledge and self taught calculus skill

[surreal sapphire]

i think tutoring is your best bet

[fathom hamlet]

Yeah I thought so, I just wanted to make sure the goal is realistic before I really commit into it

[surreal sapphire]

well, i wouldnt know

[hasty current]

I guess ur right

It’s just hard staying focused on a certain book when studying, idk what to do. Like I wanna dedicate a good amount of time to just working, I just don’t know how

[odd wharf]

@charred furnace hey

[static loom]

assuming it's not salted, then sure the rainbow table approach can work

[boreal prawn]

I'm going to be honest I don't think a gimmick like this is necessary. it's a cute idea for an SO who likes math or something similar but no reason to add a layer of obscurity which only serves your interest. I wonder if we can think of a cute/creative way to represent the date without having to decrypt it somehow, that way she'll know what it is without having to ask you, learn some math, or use a tool

an obvious choice is to omit the year and just write 30/10. could be smaller to use a different separator like 30.10

I think it'd be cute to just write it without any seperators, then it does feel kinda like a secret code since it's just random-ish string of numbers, but she'll know what it is (and no one else will)

so just 301024

you could write X instead of 10 so 30X24, or maybe the whole thing in roman numerals, but that may be hard for her to figure out without help (esp bc yours would be XXXXXXIV, which is probably longer than you want anyway)

[rocky shuttle]

XXXX

[boreal prawn]

?

[rocky shuttle]

3010

[boreal prawn]

oh yeah lol you could just do XXXX and she probably wouldn't figure it out but it'd be funny

[rocky shuttle]

and you can't interpret it as 40

because that would've been XL

[boreal prawn]

yeah

yeah? they just said it was a gift, doesn't necessarily mean it's for their anniversary

The core of the Riemann hypothesis is the phase angle π between the real and imaginary parts.
D.
Proven!

[sharp mulch]

[feral skiff]

Position of the non-trivial zero point At s=1/2 + i t, the real and imaginary parts are both zero. This condition only holds when the argument of the real and imaginary parts that make up the even and odd functions is exactly π. The only condition that holds is Re(s)=1/2. Even the slightest deviation will change the value of the real part, and they will never both become zero. The intersection point of the imaginary parts does not move. However, the peak is synchronized with the real part. First of all, this principle is the basis.

That's what it said!

[cinder zephyr]

who wants to take a bet that "it" is an LLM?

[jagged forge]

[feral skiff]

It's not a difficult calculation. I was able to do a simple calculation and confirm it, so try it yourself.

[sharp mulch]

The real part of 1/2+it is 1/2 and the imaginary part is t

[jagged forge]

chatgpt could write better slop than this

[cinder zephyr]

the real and imaginary parts are both zero
looks inside
nonzero

[fresh comet]

[feral skiff]

The formula is this.

The condition for a non-trivial zero point of the Zeta function is that the following two equations,

\sum_{n=1}^{\infty}\frac{e^{-i t\log n}}{\sqrt{n}}=0

is decomposed into real and imaginary parts,

\sum_{n=1}^{\infty}\frac{\cos(t\log n)}{\sqrt{n}}=0,\quad
\sum_{n=1}^{\infty}\frac{\sin(t\log n)}{\sqrt{n}}=0

The two equations above are "true simultaneously."

Give it a try.

There should be a kind of reverse Clay prize, where people get money taken away for confidently and incorrectly claiming to have solved RH

[fresh comet]

how much money would the collective mathcord lose

[jagged forge]

gorillions

if you also include the collatz proofs

those have got to count for something

[feral skiff]

This is not my proof. It will not be taken from me. I am not interested in the prize money 😏

[jagged forge]

you should consider the reverse clay prize

[sharp mulch]

[feral skiff]

If this is true, then the hidden element is π, right?
It's what's causing the phase angle shift.

The shift between an even function and an odd function is what you would normally think of as 90°=π/2
and when you combine the two halves of these, you get π/2 + π/2 = π.

It may not be related to that π, but it would be interesting if it was related to the Basel problem ζ(2)=π^2/6!

Also, completely unrelated, but it's interesting that the number π(x) used in the Prime Number Theorem coincidentally matches 🤣 This has a statistical meaning.

[jagged forge]

none of this means anything

[leaden torrent]

🤣 This has a statistical meaning.

it's all slop

[bronze pelican]

Agreed

[agile fiber]

it's a photoshopped version of this photo of einstein giving the 1934 gibbs lecture at carnegie university

coincidentally the lecture was actually about deriving the mass-energy equivalence

[bronze pelican]

I don't understand how u can derive physical equivalence from writing math equations on a board

Seems like crankery

What careers exist for a math amjor

[jagged forge]

i swear someone used to ask this question out of the blue repeatedly

@old oak am i crazy

[noble coral]

Counting sheep

[jagged forge]

anyway, i should probably assume you're asking this in good faith, you can go into many careers as a math major, if you teach yourself how to program then software is a viable path, though the job market is rough these days

you can also be an actuary or statistician

[surreal sapphire]

this question is asked all the time

[jagged forge]

i guess it's just deja vu or just memories of that one guy who asked the same question for months and never responded

and then got banned

[old oak]

Yes, S2, my nemesis

And never engaged with any of the responses

[jagged forge]

crazy

wonder if we search the responses if they're on reddit somewhere

[old oak]

I think the hypothesis was indeed that it was some kind of bot farming responses to feed a LLM or some other automated content generator

[inner canopy]

this goes very hard for some reason

[bright hill]

and then add it to the pot for the one that actually solves it

heya so i ended up running out of time anyways and i just ended up carving the date itself alone
also she knows she i like this kind of stuff and as of recently she has begun to enjoy it herself too
i didnt mean to put a super encrpyted thing, more like in the lines of morse or braille or (Something i wanted to do but couldnt ) put 3 circles one inside the other with different radius'ses and separate them in equal parts as so each circle by itselft would spell out one of the numbers or smth

anyways yeah i ran out of time and carving wood by hand is really difficult so i inscrybed the date.
it came out not great.
but she liked it so its cool

i wouldnt do it just for my own good or interest, i know its something she would find joy in as well

[upbeat kraken]

Is there a better way to complete the square with decimals

My teacher told me to times by 10. Or 100 to get rid of decimal

Is there a faster better more efficient way

[valid dove]

Any thoughts on adding a computer science channel? I think it would get a lot of use

[cinder zephyr]

TCS channel exists for upper level complexity theory questions

anything else is out of scope for this server

[valid dove]

ohh i didnt see that

[neat lintel]

What search engine do you guys use?

I use Startpage but it's quite inaccurate and slow ngl

I want accurate results of Google and Bing, but I don't want ads

POP QUIZ: if I wanted to add every single whole number from 1 all the way to 50 up without actually doing all the addition, what formula would I use? The formula should give the same amount as 1+2+3+4+5+6+7+8+9+10+11+12+13+14+15+16+17+18+19+20+21+22+23+24+25+26+27+28+29+30+31+32+33+34+35+36+37+38+39+40+41+42+43+44+45+46+47+48+49+50

[heavy cairn]

My ass

[neat lintel]

n(n-1)/2

So it's 50(49)/2

[agile fiber]

clever gauss etc

[still pilot]

50+1 = 51, 49+2=51, 48+3=51, … so basically, pair up these numbers, n/2 pairs, and they all sum up to the same number n+1. So we have n/2 * (n+1) for even n

And for odd n it’s the same deal. But there will be a leftover n in the middle which will be equal to (n+1)/2. So we form (n-1)/2 pairs, (n-1)/2 * (n+1) + (n+1)/2 = n*(n+1)/2. Same thing as even n

So 50*51/2 = 1275

You could sum 1+…+n + n+..+1, you would get n number of n+1s this way without worrying about even or odd n , but you need to divide by 2 since you double counted and paired up numbers with themselves . So n*(n+1)/2

@vivid halo you should check out this paper if you haven't already
https://arxiv.org/pdf/2503.13006 they developed something called the "Galois Grothendieck Path Integral"

[neat lintel]

simple, gauss method.

already answered by many tho.

[vivid halo]

Lmao crank paper

[alpine copper]

Wait actually? The author seems legit, but idk enough about this field to tell sadly

[vivid halo]

Ah okay I read it more carefully the result is sort of legit it’s just an incredibly stupid and useless result

[old oak]

A useless result, in a mathematical paper? I'm astonished

[vast wraith]

was manin a crank?

[vivid halo]

Borderline

[vast wraith]

i’m not familiar with any of his mathematics but i’ve seen excerpts of some essays of his and they struck me as pretty far out there

[maiden crane]

you guys know advanced elementary math books? (high school math books for hard exams)

[vast wraith]

The Russian version of Mathematics as Metaphor contains ten chapters that were omitted from the English version. The American Mathematical Society decided that these chapters would not be of interest to English language readers. The omissions are doubly unfortunate. First, readers of the English version see only a truncated view of Manin, who is perhaps unique among mathematicians in his broad range of interests extending far beyond mathematics. Second, we see a truncated view of Russian culture, which is less compartmentalized than English language culture, and brings mathematicians into closer contact with historians and artists and poets.

[alpine copper]

One of my professors sent this paper to me as he was interested in the path integral part

[vivid halo]

[sharp mulch]

Mathematicians try to do useful physics moment

[dense blade]

Hi
What do you mean by that ?

[inner canopy]

what was Manin even into math wise

[vivid halo]

I mean loads of stuff, lots of number theory and math physics

[inner canopy]

ah well okay maybe to rephrase

what number theory/physics did he do

[vivid halo]

Motives, rational points, elliptic curves, stuff like that

[inner canopy]

ahhhh

[vivid halo]

Most of the knots and primes and F_1 ideas originated from him

[inner canopy]

well he was the advisor of like half the people in those fields lmao

wdym by mid taste?

[rocky shuttle]

mid taste = (bad taste + good taste) / 2

[neat lintel]

no its even lesser or equal to than that
its their geometric mean

tho for this to be equal to the arithmetic mean, you'll have to take bad taste=good taste which is not possible

[rocky shuttle]

it's possible

but then it's called trash taste

Looking at Boolean Algebra and thinking, "Wait, this is just what I learned in computer science class."

The way I learned it focused more on AND, OR, and NOT than the letters, but I think my college casually taught me Boolean Algebra because our computers are built around it.

So we had to draw out the logic and stuff like that.

[still pilot]

That’s tremendous

[strange musk]

I've been trying to bond with people over math, I feel like you don't have to be an absolute god at it to appreciate the art form yet nobody seems to get as excited as they should be for how cool math is\

[still pilot]

I get it, but the last thing I want is to be around a nerd that won’t shut up about how cool some random math is

Explaining the problem to me and how it’s really fascinating because x y z

My math interests are largely personal

[half kayak]

I’m lucky enough to have some classmates that actually cry over how good the math class is

Learning the same stuff and working on the same problems and discussing can definitely be fun

do you guys know a place i can learn about vectors, like a course?

linear algebra is all about vectors

if you mean an online course about linear algebra then i recommend you check mit ocw
