serious-discussion

[willow crystal]

although i wonder who here knows about the Rule of Sarrus for finding the determinant of a 3x3 matrix. It was how i was taught :p

[old oak]

As a teacher I hate the Rule of Sarrus because students keep trying to apply it to 4x4 and larger matrices ||including non-square matrices||

[willow crystal]

Yeah it's supposed to only be applied for 3x3

[old oak]

I mean, it's often a very useful way to calculate determinants, but it's very risky to teach it to irresponsible people

Also this really doesn't take that long unless the matrix is particularly gnarly

[willow crystal]

I always get gnarly ones, i wish i was good at arithmetic :/.

Plus when they have lots of negatives in them, it makes it a bit difficult since you have to keep in check for them

[old oak]

Sounds like you're finding the inverse using cofactors?

For 4x4 and larger matrices my first choice would be Gaussian elimination

[willow crystal]

Yep. Some questions they ask you to do only with cofactors (i don't know why tbh). But i do usually use Gaussian elimination

[old oak]

I've never liked enforcing a particular method of solving a problem on my students

I mean, I do that during classes so that they get familiar with all the methods

But never on homeworks/exams/etc

On the other hand I do like setting problems where one method is patently better than another

[willow crystal]

True. I do like linear algbrea a lot anyways. I find it intresting (i did learn some of it during my a level further maths as well) how you can apply it to computer science which is what i'm doing for my degree alongside with maths

[old oak]

Yep, machine learning for instance has a lot of linear algebra

[willow crystal]

Do you have any textbooks you recommend for linear algebra?

[old oak]

Sadly no, I only teach it in the form of UG courses so all I have is our uni's official course notes in my native language.

But there should be something in the pins in #book-recommendations

[willow crystal]

Ah okay, thanks a lot

[stone ferry]

I mean it does apply

you just don't have as nice of an enumeration of the permutations of n elements when n>3

[north topaz]

are you German Outsider or did I mix you up with someone else?

[old oak]

I'm Polish

[old oak]

It does if you consider it a synonym for the permutational definition, but not if you interpret it as "just go along the diagonals"

I'll let you have a wild guess as to how the students I mentioned approach it.

[north topaz]

sorry

you're not offended right

[old oak]

Nope, no worries

[stone ferry]

Yeah I get what you mean

I remember when we defined determinant in my (second) linalg class, we mentioned the permutation method

followed quickly by "please don't use this on a test, it's gonna suck"

[old oak]

Yep

I think it's sometimes useful as a theoretical tool, to spot something etc.

Like why the determinant you use to find eigenvalues will be a polynomial of degree at most n

But I can't think of a scenario where it would be useful for actually calculating a determinant

Speaking of detemrinant calculation methods, there's also this: https://en.wikipedia.org/wiki/Dodgson_condensation

Invented by the author of Alice in Wonderland

[stone ferry]

Yeah I remember that being mentioned in the same linalg class

Apparently he got a letter from the queen after writing Alice in wonderland, asking "if you write any more books, please send me a copy"

You'll never guess what he sent in response

[eternal hemlock]

Which one is correct?

[noble coral]

All that survival of the fittest means is that those things which have some mechanism to perpetuate themselves tend to perpetuate themselves

That's all evolution, and life as a whole, is.

They are aimless, it's just that the things that happen to randomly develop ways to last longer, tend to last longer.

We just consider things that perpetuate themselves successful, but there's nothing behind that beyond our own intuition.

[old oak]

yep, it's not like those birds suddenly chose to develop different-shaped beaks

it's just that those which randomly did, fared better, had more offspring, so the trait persisted

[vast wraith]

i read a fun article on “biosemiotics” yesterday, which is like semiotics, but biology, it didn’t make any sense to me but was still fun

[noble coral]

It's interesting to think of this going all the way back to the beginning of life. I find that it alleviates all those paradoxes about the unlikelyhood of life if you come to think that all the first candidates for being the first "cell" died off except for the one that had just the right environment and just the right set of chemical reactions.

Earth just being a large, stirring, boiling pot of chemical reactions until we got the one that was self-perpetuating, and it never stopped from there.

[old oak]

Yep, also as for the unlikeliness of life my preferred answer is the anthropic principle

In the countless much more likely scenarios where life didn't develop, there's no one there to wonder why it did

[noble coral]

Mhm.

[icy heron]

He sent a mathematics book? Apparently it's not true https://www.snopes.com/fact-check/alice-in-wonderland-queen-victoria/

[vital tusk]

Lewis Carroll was a mathematician. Just letting you know.

[old oak]

Yes, that's what prompted this tangent.

But apparently the claim that he sent Queen Victoria his determinant book is false (and had been denied by Dodgson at the time)

In between writing fantastic books and photographing young girls in the nude, he also did mathematics

[icy heron]

Yes, I know 👍

[unborn linden]

photographing WHAT

[old oak]

https://en.wikipedia.org/wiki/Lewis_Carroll#Speculation_of_sexual_conduct_by_scholars_(1940s_onwards)

[mental stratus]

better discussion ngl

[vast wraith]

very true

[old oak]

I aim to please

[barren anchor]

damn that dude from magicians is probably based on L C I guess

maybe there's a bit of a cultural divide between now and then though. Like, parents in attendance? young boys and girls? daguerrotypy?

it's like all classical & renaissance art maybe

[grave badge]

@unique peak

that person made a huge fuss after i said reverse operations is something people learn at 6th grade saying im insulting her when i didnt even mean to

and 2 other people tried to assist her with a question earlier today but she was rude and closed the channel like midtalk

one even said she was difficult to work with since the beginning

see what im talking about bro

this is some bullshit right here bro

like ur receiving FREE HELP from VOLUNTEERS

atleast be fucking kind

so problematic

[willow crystal]

I guess you have to ignore those kind of people

[knotty kettle]

Hey chat

Anyone wanna

CHAT?

[grave badge]

legit

i tried to help her once more trying to forget what happened earlier today and she just hit me with the "do not interact with me"

never again

[knotty kettle]

Indeed

Let's ping the mods

[grave badge]

sure

lets actually do it

she mustve wasted a lot of helpers' time

[knotty kettle]

Then wait for it to happen again and catch her together with the mods!

[grave badge]

cuz like the other person who was helping her, she interrupted him mid convo and said shes leaving the server then closed the channel

like wtf

[knotty kettle]

Huh

That's not a nice person to work with

[grave badge]

shes still in the server btw

yeah

[knotty kettle]

So

[grave badge]

she might be trolling tho

[knotty kettle]

We wwit for her to open help channel

Then ping mods

And catch her

[willow crystal]

Probably ragebaiting at this point idk

[grave badge]

her name is "lalnashef"

#help-25

thats what she just did

[knotty kettle]

I think that's not ragebait

It's just dumb

[grave badge]

but earlier she made a big deal out of everything and was being rude to helpers

[knotty kettle]

Alr

Wait for her to open a help channel

Then screenshot

[grave badge]

uhh

[knotty kettle]

And ping mods

[grave badge]

mods can just read channel history yk

lmao

[willow crystal]

Did it came out of nowhere?

[knotty kettle]

Deleting messages exists yk

[fresh ermine]

They’ll look through the audit logs

it’ll be fine

[willow crystal]

I just checked the help-4 channel, and nobody even insulted her :/

[grave badge]

im not sure but like 2 people were already helping her (which stop responding unsurprisingly after know how she is) so i came in and helped her, it was about inverse functions and i just told her its about making x the subject and then switching it with y and she had difficulties doing that do i told her some of the steps and mentioned that its a 6th grade thing just for the sake of making it sound more easier and then she started losing her shit telling me that not everyone is good at math and saying that ive insulted her :/

about the 6th grade its not about the inverse functions itself

its cuz u have to make x the subject so u have to reverse the operations

which is somethign people usually learn in 6 grade

[willow crystal]

She probably got mad for you saying it was 6th grade. Even though it is 6th grade. Plus you dind't direct it to her or meant it in a way where she was being stupid

[grave badge]

yeah

[knotty kettle]

Audit logs don't save deleted messages afaik

[grave badge]

like i even apologized even tho i did nothing wrong but she still kept going on

[fresh ermine]

they do..

[knotty kettle]

Alright

Let's do screenshot anyway

[grave badge]

and i offered to help her again all the way from the start so she could understand everything but she rejected like then whats the point of opening a help channel

[knotty kettle]

Plan:
Step 1: catch her being rudr
Step 2: screenshot (optional)
Step 3: ping mods

Let's do it

[willow crystal]

i like how you're planning this out like you're planning taking over a country ot smth lmao

[knotty kettle]

Bruh

So

[grave badge]

#help-11 message

this is the first time

[knotty kettle]

I wanna catch her in the act, in real time

[grave badge]

#help-25 message

second time which just happened now

[knotty kettle]

She isn't active noe, let's wait

[grave badge]

alr

[willow crystal]

She seems trollish to me from what i've seen in the chats

[knotty kettle]

What is her username?

[analog charm]

you making yourself out to be a good person after puttingme down and saying i should know this stuff when i come here for help isnt okay. and then coming out here and gossping about it? really? thats awful.

i prefaced a lot of what i said with "i dont understand this andstruggle with simple concepts"

so you saying that was extremely hurtful

if you cant understand that, you are extremely just something shine. thats not okay. youre essentially bullying me atp.

[willow crystal]

Could you have not told them politely instead of resorting to an argument?

[analog charm]

its not a "big deal" when you literally insulted me and i reacted

[analog charm]

I said it calmly and then they dismissed it like it was nothing

[knotty kettle]

@unborn trellis

[analog charm]

That shit hurts

[knotty kettle]

Plz deal with rude person...

[willow crystal]

idk, from what i've seen in the chat. You started it first

[knotty kettle]

Also rude in help channel

Several times

[analog charm]

ididnt argue until she said #help-25 message
"people like you"
what the fuck is that supposed to mean. i asked you nicely not to interact

and you insult me again

[willow crystal]

You said this before though?

[analog charm]

(before, no) They shouldve stopped interacting with me right then and there

[willow crystal]

And can i ask why did you say that to them?

[knotty kettle]

Thanks for literally linking evidence against you
The mods are gonna have an easy job figuring out what happened

[analog charm]

because you changed your messge

[analog charm]

They can have fun.

[gusty socket]

you should probably just block each other

[analog charm]

Theres nothing against me here

[analog charm]

Because they (indirectly) insulted my knowledge and education several times beforehand

[gusty socket]

i can show you how if you need. i would just like the argument to stop.

[knotty kettle]

No
Lalnashef needs to be blocked from the whole server
That's called a ban

[willow crystal]

And do you have proof of this? like a screenshot or a forwarded message?

[analog charm]

shine needs to learn how to not be insensitive

[analog charm]

ive already sent it to mod mail

[knotty kettle]

🚫 , there is stuff against you

[queen tendon]

Can real analysis be self-taught? Anyone has a textbook suggestion or website?

[analog charm]

Youve only seen half of the argument

[knotty kettle]

You're the insensitive one...

[willow crystal]

I know but personally i'd like to see the message forwarded?

[gusty socket]

you need to stop arguing over it. nothing either of you are saying right now is productive or helpful for us to figure out what’s going on.

[knotty kettle]

Saying people insulted you just because they said when something is taught at school
You're the insensitive one...

[gusty socket]

please stop now

[knotty kettle]

Alright

Lemme tell you what's going on

[analog charm]

How am i insensitive when she literally told me "you should know this by now" and "this is simple 6th grade stuff" when i already told her i struggled with that stuff

[gusty socket]

please stop.

[analog charm]

okay

[knotty kettle]

So, lalnashef is rude in help channels
Gets angry over the smallest things
That's modt of the story

[analog charm]

Nope

:3

[knotty kettle]

lalnashef used DENIAL!

[gusty socket]

stop

[analog charm]

Are we gonna listen to the senior mod or

not

[knotty kettle]

When I understand what they're telling me...

[willow crystal]

Is this what you were referrring to Lalnashef?

[analog charm]

oh i had shine blocked im gonna reblock her

[analog charm]

no, thats like one of the last times she interacted with me.

Stop talking about it.

[willow crystal]

Ah okay. I just don't understand you still haven't provided proof though that she insulted you?

[gusty socket]

please stop arguing over it. i’m not going to ask again.

[analog charm]

Find it yourself. I'm not discussing it anymore.

[knotty kettle]

Are we gonna figure out this case or not?

It has to end reasonsbly, not just tucked under the rug

[analog charm]

They can figure it out without us arguing over it

So

[knotty kettle]

Hm
Maybe

I pinged another mod, let's wait for them to come

[analog charm]

That doesnt mean to keep talking about it

[analog charm]

You are wasting their time. its already been reported. multiple times probably by now.

only one ping was needed

[willow crystal]

ok

[queen tendon]

Every time I solve a question on a test, I always make an inattention mistakes. I get so close to getting 100, but yet so far. Does anyone share the same experience with me? How can I improve myself I really need help.

[grave badge]

wtf is going on

i just came back from eating

[willow crystal]

I'm actually the same tbh

[grave badge]

why is she in this chat LOL

[willow crystal]

war

[grave badge]

wait what did she say

i cba to like

scroll up and read her bullshit

whats her take on this

[gusty socket]

please don’t worry about it. i want to take it out of this channel lol. i’m just gonna recommend blocking and moving on.

[grave badge]

xD

[grave badge]

alright

[willow crystal]

I can DM you if you want?

[grave badge]

sure

i honestly dont care anymore

a moderator is involved now

so its up to her

lmao

[gusty socket]

steam scams 😭

[grave badge]

perfect timing

[old oak]

A nice palate cleanser

[gusty socket]

anyways, the incident is over now, so we are gonna stop talking about it. perhaps if someone wants to share what they’re learning that’s a way to change the topic.

[grave badge]

she has me blocked

i dont though

cuz im mature and i wont let shit like this get to me

its over now tho

peace

[gusty socket]

anyways, what is everyone learning about/reading?

[willow crystal]

ehm i read about the "Hairy Ball Theorem". That's an actual mathematical theorem lol but they also call it the hedgehog theorem

[icy heron]

I'm learning Galois theory, and I realized that I hate finding all subgroups of a given group

even D4 has like 100 subgroups

[analog charm]

:/

[analog charm]

is this chemistry?

[grave badge]

wow hedgehog and hairy ball

[icy heron]

no, its the 4th dihedral group, the group of symmetries of the square (ie. reflections and rotations)

[unborn trellis]

you're going to fucking love the classification of covering spaces

[analog charm]

ohh

[gusty socket]

me @ the one hatcher exercise when it tells me to classify coverings of RP^2 v RP^2

[unborn trellis]

blech

Z/2 * Z/2 is horrible

[willow crystal]

Yep apparently. It states (it's from algebraic topology, i don't know anything about it lol) you can't flatten all the hairs on a sphere without a single one of them not standing. (Again it's an awfully simplified expression of what the theorem states).

[old oak]

I think it's more differential geometry

[icy heron]

in a good way or bad way? 😬 I've heard there are some relations between Galois theory and covering spaces, but never learnt what they are

[unborn trellis]

there's a galois connection between normal covers of X and normal subgroups of pi_1(X)

[willow crystal]

Ah okay, i did a quick google search of it and it said it was from algebraic topology. so IDK.

[gusty socket]

many are saying this!

[unborn trellis]

that's basically the substance of the classification of covers

[analog charm]

who here likes sushi?

[gusty socket]

i love sushi

i thought about going to a place yesterday

[analog charm]

sushi is yummy

[gusty socket]

just a bit too expensive though.

[analog charm]

its worth it

every bit

[old oak]

Ah no, you're right, since it's about continuous vector fields, they don't have to be differentiable

[gusty socket]

yeah, when i’m working again i’m going to go and enjoy myself.

[analog charm]

yeah!

[old oak]

Although I think there's a related result that there is no smooth vector field on the 2-dimensional sphere

[gusty socket]

the zero vector field

[unborn trellis]

so it's the same kind of problem. classifying intermediate normal extensions of a field is finding normal subgroups of Gal(F'/F), finding intermediate normal covers of X is finding normal subgroups of Aut(X'/X) = Deck(X') = pi_1(X)/pi_1(X') if X' is normal

then when you learn about riemann surfaces, these are actually the same thing

[icy heron]

wait, is it Galois theory just because its a Galois connection? That doesn't make any sense... there has to be fields involved

[unborn trellis]

no it's galois theory because he invented it lol

mathematicians just noticed a lot of things act like galois theory

[gusty socket]

i also enjoy tea, and also this conversation has reminded me to go grab some tea.

[fresh comet]

sushi is great c:

[old oak]

As usual, zero ruins everything 😩

[fresh comet]

I’m a big fan of sashimi too

[gusty socket]

bump function on an affine set

coordinate chart*

sorry

you can just make a lot of smooth vector fields

[old oak]

Huh, so what's the one I was thinking of?

I might be misremembering completely

[gusty socket]

the topology one probably

[unborn trellis]

nonvanishing vector fields

[gusty socket]

there’s a non vanishing vector field on S^n iff n is odd

[old oak]

Yeah, probably

[analog charm]

yeah. wish i had some tea. or sushi. would help me feel better.

not feeling too great rn

[gusty socket]

perhaps a brisk walk, that always gets me feeling okay.

[analog charm]

its muddy outside

no boots.

[gusty socket]

even better!

[analog charm]

its hot and muggy.

[fresh comet]

going for a short walk and/or drinking some water tends to help me cool off

[unborn trellis]

time to teach my students who dgaf

cya later

[icy heron]

hmm, I thought Galois theory had literal applications to covering spaces, but it seems like it's only an analogue, its just Galois connections between preorders

[analog charm]

im not angry anymore just very very low

not sad, just generally a very low mood

and i have stuff to do, very behind on work which i tried to do but

cant understand it because the lessons dont help me learn the way i learn

cant really do anything else atm so

[old oak]

You could just have said "students"

[analog charm]

just sitting here

[analog charm]

its a joke (actually probably not but)

itll be okay

[astral solar]

CAN SOMEPNE HELP ME TO UNDERstaND A PROBLEM PLSS

[fresh comet]

that’s rough. do you have a plan to get back on track? perhaps a schedule might help you?

I hope you feel better soon too

[fresh comet]

hi! try asking in a help channel!

#❓how-to-get-help

[analog charm]

ive tried. i cant adhere to anything, i get burnt out and when the plans dont go as planned its even more stressful.

its just missing stuff and learning and forgetting until the school year ends and thats it

hope my senior year is better.

[old oak]

Yep, I was talking of things which I don't properly understand.

A lesson there

[gusty socket]

the only constant vector field on S^2 is the zero vector field unfortunately

also

constant vector fields don't really make sense

on things that don't have tangent spaces that you identify with each other

like R^n

[analog charm]

even though my entire high school likfe has been this way and nothing ive tried works. if im motivate i get demotivate very quickly by how quick im reminded i simply do not learn the same

[old oak]

Still, my issue was that I thought there was something separate about smooth vector fields (as opposed to the hairy ball theorem which is generally about continuous vector fields)

[knotty kettle]

Hey

[old oak]

But I think I was wrong

[knotty kettle]

What happened with the lalnashef case? I wanna catch up

[fresh comet]

you can maybe talk to your teachers or an advisor for assistance

[gusty socket]

we've moved on.

[analog charm]

the mods said not to talk about it

[gusty socket]

stop talking about it.

[fresh comet]

they might be able to give you advice

[knotty kettle]

Nice
Moderation cases are now kept secret
Cool!

👍 👍 👍

Anyway

[analog charm]

lol

[gusty socket]

what is your problem

[knotty kettle]

Wanna chat?

[analog charm]

do you like sushi parallax

[knotty kettle]

Discussion of a mod case being banned

[vast wraith]

help i read smooch vector field

[fresh comet]

I think it’s a good thing to not air every dispute out in public, in a server of 250k

[analog charm]

They are a mod, they asked you to move on, thats their job, your job is to listen. Capiche?

anyays

do you like sushi

:3

[knotty kettle]

I have to listen to mods, that doesn't mean I have to think they're right

[gusty socket]

it's time to stop talking about it. if you have a specific issue you can dm @polar panther

[analog charm]

Okay.

Thank you for being patient and kind, smay

[knotty kettle]

Secret mod cases
Nice
Well, now let's move on so we don't get a punishment...

[analog charm]

Lol

Do you like sushi

[analog charm]

Forgorto ping.... do you like sushi

if not

like it

its not that hard, just like it

sushi is amazing, youre wrong if you dont like sushi

100%

sushiiiii

[gusty socket]

@analog charm do you have a favorite kind of sushi

[analog charm]

All

Any

Polysushiamrous

[fresh comet]

I really like spicy crab sushi

[knotty kettle]

🍿

[analog charm]

ooooo its pretty good

[fresh comet]

[analog charm]

Parallax do you like sushi

:(

he doesnt.... his silence speaks

[gusty socket]

it's not for everyone

[fresh comet]

I know a fair number of people who dislike it

[analog charm]

we must avenge the lossof such a great soldier

[fresh comet]

some people aren’t fans of seafood, of raw meat, etc

[analog charm]

...rip Parallax 2025... cause of death:not liking sushi

[gusty socket]

i used to think i was allergic to crab meat

[analog charm]

sad loss

[fresh comet]

really?

did you get an allergic reaction every time you’d eat crab?

[analog charm]

im allergic to shellfish but i still eat it because i never have a bad reaction-
😭

[knotty kettle]

if leftAlone = false:
setEmotion(angry)

[analog charm]

?

huh

[gusty socket]

i am not though. i think there was something else that made me sick after eating crab once and my family got really stressed for me lol

it was a long time ago

[analog charm]

oooo not good

[fresh comet]

I’m not a moderator, so I can’t tell you what to do, but I think not making incendiary comments would be the kinder thing to do

[fresh comet]

I see

that’s a shame, cause crab is awesome c:

I do prefer lobster though

[gusty socket]

wait, i'm not allergic to crab

[fresh comet]

I know!

I meant like, it’s a shame that you thought you were

[gusty socket]

ah

yeah

[fresh comet]

because you probably missed many opportunities to have it when you were younger

and it’s awesome c:

[analog charm]

im allergic to crab but i dont care i eat it anyays

i dont get anaphalaxis so

i must be fine!

hey pheonix!

[south kelp]

Ihi!

became allergic to nickel when i turned 12, before that I could play the violin just fine. Then the headrest started to give me a rash on my neck and it turned out to be cus if the nickel in it

[gusty socket]

oh no

[analog charm]

oh wow, thats harsh

can you touch nickels!?!

[south kelp]

Yeah cause nickels aren't made of nickel

[unique peak]

interesting ping :/

[analog charm]

i thought they were a mix of nickel and copper

[analog charm]

lets not talk about it anymore

[unborn meteor]

the nickel is on the inside iirc

[analog charm]

mod has asked us not to

[south kelp]

oh hmm

[unique peak]

I think that was me as well 💀

[south kelp]

Well maybe the alloy does something to it, or maybe I've just never tried putting a nickel on my neck lol

[analog charm]

why is it grey then? its mixed with copper

[analog charm]

Hey, we arent talking about it anymore

[analog charm]

ohh okay

[unique peak]

I mean, perhaps you learn the computational methods for doing so, but to really understand an inverse, you need some set theory

[grave badge]

why are you responding just now

lmao

[unique peak]

I was in class 💀

[grave badge]

well we cant talk about it anymore

or mods gon be mad

[unique peak]

i was just checking the ping ¯_(ツ)_/¯

[grave badge]

yea ik

[fresh comet]

in any case, I would advise against gossiping about other users in public behind their back

[unique peak]

^

[fresh comet]

if you have a problem with somebody, DM @polar panther

don’t bring it here

[unique peak]

to be fair, at least you pinged me when mentioning me lmao

[grave badge]

i wanted to give @unique peak some context but i couldnt do it on the channel it was currently happening in cuz it was a help channel

[unique peak]

I see I see

[fresh comet]

fair, but you should hopefully know that it’s almost akin to public humiliation/shaming

[unique peak]

^

[fresh comet]

and that kind of thing isn’t what we want

[grave badge]

yea but its more of a personal problem telling mods about it wont do shit lmao

yea i get it

[fresh comet]

if somebody is disruptive in the help channels, the mods will take action

[grave badge]

didnt mean to humiliate anyone tho it was all just context for someone

[unique peak]

I think the mods see this as a personal conflict.

[grave badge]

yea thats what im saying

so they wouldn’t do anything

mod tickets are usually only for reporting rule breakers

[fresh comet]

it is what it is then. let’s stop talking about it and move on

[analog charm]

i agree

oh, smay, has it been handled? where do i ask to see the status of reports?

if responses arent automatic

[gusty socket]

we don't give the statuses of any particular user. please just move on. this is a personal conflict and the discussion for it doesn't belong in this channel

[analog charm]

my question wasnt that. if this is viewed asa personal conflict are the mods in my ticket going to tell me that?

or do i need to ask in my modmail ticket

and personally, i do see a rule break but i dont want to annoy mods by messagingmodmail over and over

[fresh comet]

dang it, the talk about sushi earlier is making me really hungry

here's an interesting question that i am unsure the answer to off the top of my head: if you have a C^2 structure A and a C^2 vector field X on M, is there necessarily a smooth structure on M contained in A such that X is smooth?

I don't know why this question came up in my head, it was just inspired by your hairy ball theorem discussion

i'm not even sure if it's a good or interesting question :P

Inverting a 4x4 matrix is computationally difficult, assuming that the inverse actually exists

and even then confirming the existence of an inverse can be annoying depending on choice of method (computing the determinant of a 4x4)

though there are much easier ways to check

such as showing that ker(T) = 0, that the columns are linearly independent, etc...

[weak monolith]

8x8x8x8x8x8x8x8x8x8 board
ppl have 10 bishops, 1 king, 1 queen, 10 rooks, 10 knights, in an 8x2x2x1x1x1x1x1x1x1 placement, with 256 pawns
queen and king are placed at the center of a edge, the bishops are places so that the coordinate sum of each bishop ends in a different digit, the rooks and knights are places arbitraily, the two edges are chosen to be maximally distant, they board is colored with 10 colors, each bishop must move move an equal number of spaces in each axis per move, each knight moves 2 in one direction and 1 in an other direction, the king can move upto one space in each direction, the queen can move so that the direction moved in each axis is either 0 or equal to each other, the pawn moves one space ni one axis, and must move away from the original edge (unless on the first move, in which it can move 2 moves), or unless it is capturing, in which it can move upto one unit in any direction as long as it goes away from the origin edge, en passant allowed, promotion happens when it reaches the opposite edge

i vastly prefer 6d chess

[old oak]

Wait, how do you fit 260 pawns in an 8x2x2 formation?

[magic sleet]

you dont, it covers them

on each side

[old oak]

Covered in pawns

The dream

[magic sleet]

yep

not on the corners tho, that would make the calculation more difficult

specifically i did 32(1/1+1/1+1/1+1/1+1/1+1/1+1/1+1/2+1/2+1/8) = 32(8+1/8) = 256+4 = 260

oh

i over counted

i need to subtruct

oh thats nice

exactly 256 pawns

Ok

[torn iris]

@tired cargo can I PM you?

[gray spindle]

im kinda in a mix between both. though issue with nihilism im seeing is that when life doesnt matter, nor does personal connections that much and interactions always feel lonly. im currently trying to get out of nihlism but not sure where to go

[willow crystal]

Have you looked into existentialism and Nietzsche?

Or i guess Albert Camus too

[surreal sapphire]

or sartre

[gray spindle]

ive looked into nietzche but i dont think nietzsches philosphy gets rid the loneliness aspect

i havent looked into those yet

what are they about?

[willow crystal]

There's also Arthur Schopenhauer, i believe there was smth called Hedgehog's Dillema as well

[willow crystal]

You can think of Existentialism as finding your own meaning (although that's an awfully simplified definition of it). Albert Camus was a French philosopher and author who is mainly famous for writing The Stranger and Absurdism

[visual topaz]

Nietzsche's nihilism isn't that nothing matters. Or rather I wouldn't simplify it to nothing matters. It's a response to nothing mattering

[inner canopy]

I was in a similar spot when I was back in HS
Later I got diagnosed with clinical depression lmao but still
I've always personally found that like relying too much on "mainstream" philosophical angles will just make you feel even worse
In my experience at least it's always been a thing of like "this is supposed to make me feel better but it's not really helping"
It's important to develop your own lore in a sense, to not rely on those that came before for too much other than inspiration for what to look at in life instead of just reading that stuff and sorta accepting it as fact lmao

[willow crystal]

Yeah besides i'm pretty in some of his works, Nietzsche did advocate against nihilism

[inner canopy]

everybody should just waste their life trying to understand hegel lmao

learn the category theoretic viewpoint on hegel

[visual topaz]

There's nothing wrong with mainstream philosophy, you'd still need them if you want to communicate your philosophy to anyone
I also don't think one should treat philosophy as self-help. It's not designed for self-help, it's for you to better understand your own beliefs, thinking, and overall a good way to see what is sound and what isn't

It's important to develop your own lore in a sense
^ I'd say this key line is what is philosophy. It's not the abstraction or 'justified true belief' nonsense. Philosphy is finding your own answer

[inner canopy]

I felt like saying it because a lot of people fall into the trap of just reading whatever X author wrote and saying this is what I believe now word for word 💀

[visual topaz]

that's funny because I think undergrads who are forced to read any stupid theory hardly believe in them,which is the expected response

[willow crystal]

💀 . Yeah a lot of people tend to do a lot, and uh try to make it sound like it's the superior belief

I mean for example if religion works for you, there's nothing wrong with it as long as you don't force it upon others

omg croatian?

[torn iris]

Ye, u?

[barren anchor]

what are you guys even talking about?

let me school you both really quick: please read the birth of tragedy

nietzche is extremely poorly understood. Nihilism is in fact a rejoicing in the fact that the narrative dynamic of life exists between the apollinian arrangements and the dyionisian as an ongoing counterplay

he uses schopenhauer's end of individuation directly as an analogue for passage into the dyonisian

it's not even been about "mattering".

it's not a response to nothing mattering.

it is just a way to view two different things, order and disorder, and appreciate the progression from one to the other.

and of course to appreciate disorder for itself

[visual topaz]

i disagree

[barren anchor]

man this convo I cannot believe I missed this. If we're talking about phenomenology, I think hegel is definitely the hardest epistomological work I've read

[barren anchor]

yeah I think you then cannot have read nietzche

or you perhaps skipped the birth of tragedy, which would be an absurd study plan, because his other works are mostly trash

[barren anchor]

spinoza makes a lot of similar points in improvement of the understanding with about 1/10th the brain power required to read it

[visual topaz]

don't think this is the point of birth of tragedy from a quick glance

[barren anchor]

you literally quite obviously have not read it

if you want to somehow argue about it's content now, I find that bizarre

[neat lintel]

oh an actual convo

[barren anchor]

watch out!

[neat lintel]

where would u suggest one starts philosophy ?

[barren anchor]

the birth of tragedy was my first book, my dad got it for my 14th birthday. I loved it.

[neat lintel]

should i just look up some undergrads syllabus ?

[barren anchor]

it's absolutely beautifully written

that is not a bad way to do it.

if you have particular interests, you can go there. There's a huge difference in difficulty though

I wouldn't recommend Hegel's phenomenology or a discourse on the method to anyone new

[neat lintel]

wouldnt the work of someone like neitzche be far more complex to comprehend for someone nee to philosophy tho

[barren anchor]

a lot of people start with lightweights like Kant and they use excerpts, rather than somethign like a critique of pure reason

[barren anchor]

no, it's not.

[neat lintel]

ooh interesting

[barren anchor]

it's extremely easy to understand. There's some relevant background about dionysus and apollo as they stood relative to the arts and sciences in ancient greece

but he explains what you need to know

[visual topaz]

Kant is a good start

So is Plato

[neat lintel]

so i can just read it without any prior background in philosophy ?

[barren anchor]

I wouldn't read the republic, either

use excerpts

[visual topaz]

Wouldn't recommend any of the 15+ century until you have an idea how of it's written

[barren anchor]

yes, and that's the way to do it

[neat lintel]

yeah this is what i hear a lot

[visual topaz]

I would recommend reading the republic actually

[barren anchor]

p.s. I have read a shitload of epistomology, more than any other genre of literature by far

[neat lintel]

ouh

[barren anchor]

I don't know what that means and I don't agree.

you can pick up a discourse on the method and understand it immediately

I would say the 1600's is the richest century maybe ever for philosophy

you don't need any precursors to understand it.

it's philosophy, e.g. reason. Most solid works provide what they take a-priori and proceed from their.

[visual topaz]

15+ century is probably wrong

maybe 18+ century

[neat lintel]

so is there like a progression in complexity in philosophy or anything...? like uk as u said, building upon itself and previous works over time ? just wondering abt that

[visual topaz]

let me check my timelines

[barren anchor]

this generally doesn't matter in philosophy because critical and complete works tend to include what they take a-priori

as well as work through their assumptions etc

[visual topaz]

Yeah >18 or 19+ century is basically modern shit, it's not what I recommend. Starting from Renaissance/Greeks is common

[visual topaz]

For starting out I don't think you want modern stuff

[barren anchor]

I don't think so either

[neat lintel]

OH so theres almost no gate against any work, or requirement of prior work to understand any particular work in philosophy ?

[barren anchor]

I would go up to like 1850 maybe

[visual topaz]

somewhat no but if you know prior work a work is responding to, it matters

[barren anchor]

like, I wouldn't even consider somethign written after that if I were just getting a basis because the earlier works really did just cover a shitload of ground

[barren anchor]

you can know the context in which ideas which are reused came from or not, it's not critical

[neat lintel]

so the works after that period of time sort of kept making their works on that established ground work, thats why its hard to understand than the works prior to it ?

[neat lintel]

oh well

[visual topaz]

it's not 'hard' it's just that you're missing context

[neat lintel]

yeah that

[barren anchor]

no I'm saying works after 1850 are just derivative and they began to become more fussy / nuanced, reusing many larger established ideas and logic from prior works

like if you want to survey philosophy or get a handle on a lot of big ideas, the older works are more dense with those

less about extending or dealing with contradictions or resolving particulars

[neat lintel]

hm

oh well, my eyes are failing me now ig

cya

[barren anchor]

lol later

p.s. whatever you do, don't get into popular philosophy. There are a shitload of people who just rip off old philosophies and repackage them, like "Oprah's stoicism" or "Ninja's phenomenology"

[willow crystal]

i did not know that 😭

[barren anchor]

yeah some of it masquarades as self-help or self-improvement shit

it is annoying. Like you wanna understand things? decompose them to simple ideas. Like, ok.

stfu.

[willow crystal]

Some of the self-help is annoying tbh. Besides most of them ask you to buy there pyramid schemes lol

[visual topaz]

philosophy is not self-help

[barren anchor]

yeah it's annoying af

you'd be surprised. stoicism and virtue ethics particularly. "how to be a better person, by marcus aurellius" ok

[visual topaz]

anyway back to this, looking a lot more lol yes. it's also interesting how it's very separate from Nihilism but honestly makes sense

[pearl tiger]

[willow crystal]

I read stoicism a bit. I thought it was alright. A bit similiar to buddhism

[pearl tiger]

It's a very small question though

[barren anchor]

it's actually not, it's a basis for thinking by which your provision to the meaning of life changes death from something bad to something joyous.

[robust brook]

you can still open a help channel

[barren anchor]

it is an application of nihilism to choose to understand it

[visual topaz]

I don't think he went ahead with this idea too much

[barren anchor]

...

well, I think you should not talk about a book you haven't read so much

it's definitely grating on me at this point

[visual topaz]

The Apollonian and Dionysian? Don't think it features much

[willow crystal]

I'm pretty sure he did? Have you read the Will to Power?

[visual topaz]

You said everything else was "trash" too

So

What do you mean by "This"

[barren anchor]

he's talking about strictly in the birth of tragedy

[visual topaz]

I understand Will to Power

I don't think the greek dynamic persisted too much

[willow crystal]

Apollonian and Dionysian i think is to do with action and non-action. It was referenced a lot by Nietzsche

[barren anchor]

this is what I was rebutting. I think it was clear.

[visual topaz]

This doesn't gel with what I understand of Apollonian and Dionysian as reason vs chaos

[barren anchor]

in terms of extending this basis into his other works, I agree, it's not present

unless you read into it

[barren anchor]

yeah that's not what it is

[visual topaz]

So you're saying it's there, just not written explicitly?

[barren anchor]

to me nihilism is the collection of nietzche's thoughts, and some aspects of BoT appear in W2P

[willow crystal]

I haven't read much of the Birth of Tragedy. Only Will to Power

[barren anchor]

yeah. The entire subjectivism of the content

[visual topaz]

Seems common to me

[willow crystal]

Though i think Apollonian and Dionysian is open to interpretation anyways. It is mentioned a bit in Will to Power

[barren anchor]

a great artist is kind of like a nihilist in a way

that's most people's case

[willow crystal]

I've heard it was to do with non-action and action from what i've heard by my friends who does philosophy but eh ¯_(ツ)_/¯

[willow crystal]

What makes you say that btw?

[barren anchor]

I don't think you've read any of this so it doesn't matter dog

[willow crystal]

Nah i'm just intrested in your reasons

[barren anchor]

well I've gotta do work so another time maybe bro

[willow crystal]

bro 😭

okay than bye lol

[visual topaz]

Seriously don't get this when the writer writes God is Dead

[willow crystal]

I think what Nietzsche meant by God is dead, is the influence of religion is dead

Since i'm pretty sure during that time, Nihilism was a big movement in Germany

When it was quite religious before

[visual topaz]

It's not that the influence of religion is dead, but that it's difficult to believe in the christian God

And with that, a lot of morality

[willow crystal]

Yeah i think you're right when i think about it. Nietzsche was probably remarking that though God has been the answer to the question of 'why is this good/the right thing to do?', this is no longer the case, and we (that is, each individual person) must be their own moral foundation.

[visual topaz]

Not sure about the moral foundation part (don't really get the ubermensch stuff), but yes I think the idea is to react to this social change. Hence I keep saying it's a response

There's almost no greater nihilism than the death of belief in western culture

And that's what Nietzsche (is thought to) was writing about

[willow crystal]

There is a concept of Master–slave morality. So i suppose i was commenting the moral foundation part from that.

[willow crystal]

True. I think Secularism is mainly replacing religion.

Also athiesm as well

Though athiesm is a lack of belief in religion so that might not be a good example lol

[visual topaz]

IDK if he was writing with any intent on this in mind but he definitely did analyze this

Anyway I think I did read more Nietzsche in the last 60 mins than I did in my undergrad, which is nice

[willow crystal]

Yeah. Though i dind't do philosophy as a degree but more of a casual reader of it. I am just saying what i think i interpret the idea here.

[willow crystal]

Lol

[visual topaz]

I've only read the intro so far

[willow crystal]

oh okay 😭

[visual topaz]

Don't really get it tbh

Everything is an object, objects interact with other objects. The interaction involves public interfaces (I think?) but objects have a lot of hidden qualities (unknowable by other objects I guess)

[willow crystal]

this actually sounds like OOP though fr lol

[visual topaz]

Yeah that's probably why it sounds similar. But it's this but as an ontological theory

[willow crystal]

Currently, i've been reading a bit of Dostoevsky. I've just started Notes from the Underground

Which is why I stay outside #discussion for the most part

[vast wraith]

as anyone who value their continued well-being should

[mint canopy]

Woah

👁️👄👁️

I've never had the privilege of seeing this in person

thank u for enjoying my post Outie

[old oak]

I felt like it wouldn't be in the spirit of AI, were I to give you credit

And in seriousness, apologies; credit to Boytjie for posting that in another discord from where I shamelessly snatched it

[sharp mulch]

[mint canopy]

To be clear I wasn't criticising you

I have no problem with you sharing it

[old oak]

Wow, that's a new one!

[mint canopy]

I just have actually genuinely never seen this happen. I've shared other people's posts, but I've never seen someone else share mine!

So it's fun

[gusty socket]

welcome to the mathematics discord server

[old oak]

It's all I've dreamed for, and more

[robust lake]

hey

[fresh comet]

apparently, I don’t value my well-being

actually

you know what?

I agree with that

[vast wraith]

i need to learn to value my well-being too

[zealous basalt]

Is anyone available to discuss Permutations, Combinations, basic/advance probability via call? I have a mid term for my MAT 142 class tommrrow and there is a few things I dont have clear yet.

[old oak]

So #bots tells us, yes

[fresh comet]

you're right

[zealous basalt]

p;[p;[p;[p;[p[;;;;;;;'/;

[old oak]

Finally, someone coherent in the mathcord.

[fresh comet]

:o

[polar monolith]

hello

i need help with premutation

[jagged forge]

i was scratching my head for a minute trying to figure out what was wrong with this

[mint canopy]

The highlighting was automatic btw

And a bit misleading!

[glass peak]

Could you not

<@&268886789983436800>

[flat harbor]

huh

[cold needle]

?

[velvet dagger]

Dead

[cold needle]

who the fuck is larry vro

[glass peak]

Wonder what the thought process there was

[cold needle]

Da bird...

Larry is him

[cold needle]

i see

[ocean cipher]

Is there any apps for Further mathematics tests, exams, quizzes blablabla etc?

(Preferably for phone)

[neat lintel]

true math content is in books and their exercises, not apps. but if you really really really want a app, i guess khan academy will do. what is "further mathematics" anyways?

[ocean cipher]

A-level maths.

Further mathematics is advanced mathematics.

[neat lintel]

math has many steps and takes a great while to get to an advanced level, i'm not at that level myself.

how much do you not know?

[short plover]

All of it, I have a slug in my head where my brain should be, I know you weren't asking me but I'm so frustrated at myself for slacking in school

[ocean cipher]

Oh, I’m 13 and know better than university students and further advanced mathematicians so.

[neat lintel]

well doesn't seem like you need to learn any more at all, so i can't help you really.

[ocean cipher]

Nah, I just wanted to test if I’m stupid or not what would you say is the hardest thing in the khan academy app?

I’ll try it.

[neat lintel]

that's the right spirit. just don't give up.

the more you do not know, the more you have to learn. a tautology really

[short plover]

I know but it's like looking at Mount Everest from the bottom

[neat lintel]

i know that feeling

i thought c*-algebras was at the summit, something i could never reach, for example

but it just keeps going

and going

[short plover]

It makes me want to cry, I want to understand physics better but I need math

[neat lintel]

try not to the climb it all at once

if you study every day even just a little bit

like 30 minutes

i'm sure you'll see some change

one step at a time

[short plover]

I'm old, I'll need to study more! Time to grind. Probably should seek an introductory book but even there, I'm clueless.

[neat lintel]

hmmm, "basic mathematics" by lang is the usual rec

but i find it to be a bit much for a complete beginner

but i genuinely do not know anything simpler, sorry.

[short plover]

Thank you!

I will find a copy immediately

[neat lintel]

just try to pick it at a library first...

id feel bad if you spent money just for that

but you're welcome.

[short plover]

Money I have, time is more valuable to me

I'm 34, that means by my depressing math I have roughly 16 to 30 years before my brain caves in on itself like a dying star

[neat lintel]

well

"the best time to plant a tree was twenty years ago. the second best time is now."

but im getting too pretentious

just do it

[short plover]

I will, thank you

[neat lintel]

looking for light blue grid color graph paper composition notebook no margins recomendations please

[agile fiber]

surely it would be easier to just look for one in a local school supply store than attempt to get recommendations out of every channel in the discord

[true zinc]

^

[neat lintel]

those books dont exist where i live

doesnt even have a translation

amazon

and ilr went to like 10 libraries

[neat lintel]

anyone willing to help me compare graph paper composition notebooks

rosmonde, tops store, enday store and veeboost

on amazon

[warm umbra]

welcome to the erver @short plover

[peak oyster]

yk those bitcoin miners? i want to have my own of those but for finding primes.

[ocean path]

isn’t there a project for that

where you can like contribute your computational power to finding primes

or was it finding digits of pi

idk

[peak oyster]

yeah

GIMPS

[ocean path]

yes

quite

[peak oyster]

i'll just buy like 10 computers and just download GIMPS on them/pipedream

[reef carbon]

@split ocean

help channels are not intended to remain open overnight.

if you have to go to sleep, proper protocol is to close the channel, then in the morning, open a new one -- or in fact it is much better to just not open channels if you are unsure that you can remain in there.

[split ocean]

I waited for like 3 hours for a question to be answered

I did know I could stay there

Didn’t realize it would take 12 for a question to get an answer

[brazen mulch]

1. it is correct that you shouldn't expect a help channel to remain open for long periods of time.
2. that one went unsolved and dormant automatically.
3. statement 2 is not the fault of the helpee.
4. you all can be gentler.

[tawdry arrow]

oh mooods 🤓

[karmic walrus]

Hoi

[glass peak]

Who even are you

[tawdry arrow]

does it matter

no

[vocal vessel]

The Brits have a great word for it.

[tawdry pecan]

Yea it does

U arent from around these parts, pardner

[fiery shell]

Can someone explain the logarithmic rule to me in either danish or english if you want to?

it's used in some types of equations from what i can see.

[tawdry arrow]

i own these parts

[weary birch]

anyone here took the digital sat? im taking it tmrw for the first time and im freaking out. pls give me some tips and tricks😭

[mint canopy]

I would give you the general advice to have a nice meal and get to bed early, and remember to set your alarm. Also don't get takeout just in case you get food poisoning.

Besides learning the material, there are no tricks to any particular exam.

Oh and one last thing. Make sure you visit the restroom before the exam.

That's all of my advice!

[tawdry arrow]

answer the questions correct
