Hi

[heavy gust]

Elo

[foggy meadow]

I thought I'd try.

[foggy meadow]

Again I like lattice modles, so a lot of stuff like this can come up with them.

[dapper badge]

What's the connection between your lattices and Cannon-Thurston maps?

[violet vector]

Is anyone here from Singapore?

[tawdry pecan]

no

[foggy meadow]

Uhh, more so trees and Cannon-Thurston maps if anything.

[dapper badge]

Oh sure, I guess limit sets of representations from the Bers slice are dendrites, or injective images of R-trees

[foggy meadow]

Yeah, that's one way to look at it.

[foggy meadow]

I'm in this weird space between curves, trees, graphs over trees, and encodings. Which is cool and all, but like very deep if you let it be.

I'm still stuck at the surface and haven't defined anything too deep yet, because I have to work my way up to it properly.

[dapper badge]

Yeah I mean these things can get very involved very quickly. R-trees in general are wild, but there are pretty strong structural results once you impose a group action in the background. Geometric group theory is able to say a lot about R-trees and graphs over trees and other spaces you seem to be interested in

[foggy meadow]

What interests me are just the embedings.

Like a topology or flat space can be represented by an alphabet and a curve. And a point on that curve can be a point on a lattice or tree. This allows me to talk about a topology easier, and make me wonder about different embedings using things like a mixed radix.

Or even Roman numerals for example VI = IVII = 4 but symbolically VI isn't equal to IVII. So, what's the curve or topology this represents?

I can start to ask things like this.

[dapper badge]

I'm not sure I follow, but seems cool

[foggy meadow]

It's a weird concept, but how you encode your data matters is literally the whole thing.

Like if IIIV = VIII = 2 then is this a way to represent f(x) = abs(x)? If so then I can talk about the absolute of x just with a random different encoding. On the surface this seems boaring, but what it imply is something also deep.

#❓how-to-get-help

[zealous garden]

That's tragic @foggy meadow

[foggy meadow]

For some reason this Kleinian groups remind me of the Prüfer group.

[dapper badge]

Interesting. I'm curious why, since Kleinian groups are usually far from abelian. We have a good handle on what abelian subgroups of Kleinian groups look like

[barren tree]

hello guys

can yall help me on a question

[foggy meadow]

Well if these are how they seem to look [1][2], then there definitly could be.

There almost like 3d apollonian gaskets, but I don't know how this is exactly space filling on a sphere. Or space filling at the boundary, but it's certainly interesting.

[barren tree]

disoneguy do u mind helping me with a question

[foggy meadow]

#❓how-to-get-help Idk if it's like a simple math problem then 50/50.

[dapper badge]

this one from Calegari's post is an example of a plane in H^3 arising from a complete hyperbolic structure on a 3-manifold fibered over S^1. The theory tells you that it meets the boundary sphere in a space-filling curve. This is a finite approximation to what the space-filling curve looks like

[foggy meadow]

That looks more space filling, but what if I don't go to infinity, but only can limit towards it?

[dapper badge]

Then you live on the embedded plane

But the Cannon-Thurston theory says that there's a continuous extension to the boundary so it's ok

[barren tree]

dang what level math is this

[dapper badge]

This is hyperbolic geometry and Kleinian groups

[foggy meadow]

Well then what's the embeded plain?

[dapper badge]

The embedded plane is all of the yellow and brown stuff in the picture

It looks disconnected because of how the program decides to approximate

[barren tree]

age?

level

[foggy meadow]

Passed highschool math and some colledge prolly.

[barren tree]

ok

still a long way to go

[foggy meadow]

Well, now I have a complicated task.

[dapper badge]

A good case study for some of this is Schottky groups, which is how he generates the universal cover of the handlebody inside H^3

[foggy meadow]

;-;

[foggy meadow]

Well the point of having a space filling curve like a z-ordered curve is so I can use that embeding.

[foggy meadow]

Basically my question becomes, what's the encoding of this curve?

If I can't use it for encoding then it becomes somewhat useless for me.

[dapper badge]

I don't think I understand what you mean by encoding a curve. The curves and pictures above arise naturally from discrete subgroups of PSL(2, C)

Are you trying to see if a given curve arises as the limit set of a Kleinian group? That seems really hard

[foggy meadow]

What's the discrete subgroups of PSL(2, C)?

[dapper badge]

That's the definition of a Kleinian group

[foggy meadow]

Is it a finite group?

[dapper badge]

It can be, usually isn't

[foggy meadow]

Okay, is there a link to the finite ones?

[shadow cosmos]

Hii

[dapper badge]

The finite ones are exactly the finite subgroups of SO(3)

So they're either cyclic, dihedral, or the symmetry of a Platonic solid (so A_4, S_4, or A_5)

[foggy meadow]

I guess I should've seen that coming.

I think I've come full circle.

[dapper badge]

There's a lot of interesting geometry around the finite ones too though, I think the thing to look into is the McKay correspondence. I'm not so familiar with this story, but I think the idea is that once you have a finite subgroup G of SL(2, C), you can form the quotient C^2 / G which is identified with some hypersurface in C^3. I guess the hypersurface singularities reflect the structure of G or something like that

but anyways the finite subgroups of SO(3) can be classified by hand just using orbit-stabilizer. That's a fun exercise

[vast wraith]

whoa this is an awesome illustration

i rly haven’t looked at 3d hyperbolic geometry at all

[foggy meadow]

Looking at the finite subgroups of SO(3) there are the Regular tetrahedron, Cube or regular octahedron or Regular icosahedron. All of these shapes are made out of squares or triangles which can self tile. But around their vertices there will be slightly higher density. The icosahedron might be the best to use, but still will be off slightly in the long run. And then there's the fact of me having to figure out what rotation operations equate to. Each one will have it's own regular sort of boaring space filling curves then.

Idk what to do now. Like this just is the same as me saying "a point on the circle is just a point on the boundary of a quad tree." Which is sort of underwhealming.

[fresh comet]

[dapper badge]

It's really amazing, I didn't know much about it until this past year. Something people talk about a lot is the relationship between 3d hyperbolic geometry and 2d conformal geometry at the boundary. This really does get exploited a lot in the subject and is incredibly fruitful

[vast wraith]

i should pester you more about conformal stuffs

[foggy meadow]

I'm guessing this is used in physics a lot?

[dapper badge]

I have no idea. I think the AdS/CFT correspondence has something to do with this, but possibly in higher dimensions. In 3d it's especially strong since conformal geometry in dimension 2 is none other than complex analysis, which is also 2d hyperbolic geometry by uniformization

[foggy meadow]

Huh.

I'm going to have to learn more math, and probably sets in such to talk about the things I want to talk about.

I feel like it should end up being simple.

[dapper badge]

There's a lot out there to think about

[foggy meadow]

Well I'm more so trying to program stuff and finding the best approch to do that.

[bronze pelican]

Interesting

[thorn wren]

Type ADE stuff is what got me interested in rep theory

[magic python]

ADE stuff is what got me interested in rep theory

[crisp fulcrum]

Awesome

[elfin smelt]

this isnt specifically what got me interested but this is such a good reason to be interested in rep theory

tfw all other dynkin diagrams are quotients of ADE by graph automorphisms

[latent edge]

The way I got into rep theory is kinda dumb

but it works whatever

[gleaming goblet]

I'm a little insecure about the university I'm attending; it's ranked 30th in my country, it's not the best, but was the one that best suited my context. Could you help me "rating" the list of subjects I'll be taking throughout my undergraduate studies?

[latent edge]

What's your major

[gleaming goblet]

That's the problem, in my country there's no such thing as "major or minor". I'm studying mathematical engineering, (I'm looking for an outside perspective. I have a list of all the courses I'll be taking; I can share it here if that's appropriate.)

idk, well here is the list, https://ctxt.io/2/AAD4ewykFg

any feedback would be very helpful; some courses don't make much sense, they could even be considered filler, idk, in total my degree last 4 years (I'm in my second year)

[latent edge]

Some look legit

I don't understand how would you take measure theory if you don't have any analysis

[gleaming goblet]

I know, it's strange; maybe they'll include something like an introduction? who knows... how would you rate it from 1 to 10? I'm looking to do a master's degree in the future to make up for it a bit.

[latent edge]

Are you in the US?

[gleaming goblet]

Mexico

[latent edge]

Oh I see

Yeah idk anything about mathematical engineering but I can say things about the math courses

I see numerical analysis and similar courses there which are very useful to know if you want to do applied stuff

So that's a good sign

[light thorn]

Yet again another homework I could only turn in partially complete. Well, I did turn it in fully complete, with only 2.5/5 questions I'm sure I even got right and didn't just get

how does this keep happening? this is even with extensions.

This is what I do with the disability aids and shit. With tutors and help.

[chilly totem]

what happened

[light thorn]

Turned in an assignment complete but botched

[chilly totem]

damn bro what disability was happened

[light thorn]

Well, actually the accommodations I have are only really for the tests, I think... I never actually talked to disability services in a while

but still, I keep failing in the same ways over and over again

there's "improvement" but not enough to matter

[full hornet]

realsame

[chilly totem]

keep trying bro

i am so cooked for discrete maths

[chilly totem]

talk to the services if you need help

[light thorn]

I wonder if help will even matter at this point, it's all 6/10s for the scores for the past whatever hws

[torn talon]

@honest thorn are u here

[honest thorn]

Ok for the first one isnt that just euler

[torn talon]

no, euler is umm wait i guess

but his method does not add angles does it

i mean , like basically, we do the XY rotation, and then we do anothe one in XZ but this time by the tilt angle of the plane

We use the same method to rotate

should i explain further

[honest thorn]

Idk maybe im misunderstanding

[torn talon]

why what are u mis-understanding?

still here? @honest thorn

[honest thorn]

yeah

[torn talon]

ok so if u are confused with my explanation, what should I elaborate for u?

essentially, we do one planar rotation by theta and then do 1 or 2 subsequent rotations by alpha and beta which are the tit angles

tilt

this was the first method, and it works well for single point rotations, but the setup process kills it when used for multiple points around the same tilted plane

[honest thorn]

ok whats the other?

[torn talon]

we need to calculate 2 radii or 3 depending on the numebr of tilted dirrrections and 2 or 3 tans and then just 2 or 3 adds

..............................

The other one is based on unit vectors

[honest thorn]

ok

[torn talon]

wait

we use this formula found off the web:

Pnew = Pold + ((cos(theeta) - 1 * u^ +sin(theta) *v^

we kind of drag the projection of our point by theta on the tilted plane using u hat and v hat the basis vectors of that plane

so i belivee u hat is 0 degrees and v hat is 90 degrees on that plane

and we find u hat and v hat by starting out with a unit circe on XY of either 0(for u) or 90(for v) degrees

using tan

but we normalize x and y so r = 1

so then, we perform 2 planar rotatiojs, one in XZ using the first tilt angle of the tilted plane and then in YZ using the other (if given) tilt angle of that plane

how do we perform them, well we just take the existing angle which is generally 0 the first time around and if we do it for the second time for like a double tilted plane, we calculat eatan. add the angle to be rotated to it. Calculate tan of that new angle and update the poins.

Oh and yeah we take the normalized values of tan i guess and and have the answer interms of X an Y or X and Z

or rather X and Z or Y and Z

we do this twice for u hat and v hat

and use the formula

you got all that

@honest thorn

[honest thorn]

I'm not an expert but i feel like your rotations are still in the euler coordinate system?

[torn talon]

not really

they are similar to matrices if anything

this formula is actually a variation of the rodrigues projection formula for abitrary planes

sooooo... what do u think?

[honest thorn]

Oops im dumb

[honest thorn]

isnt it really hard to calculate rotations here compared to other systems

[torn talon]

why, whats the problem

once u get up and going no

you just use the fomula

and done

I suspect it is faster than matrices, in rotations where u rotate a bunch of points in the same plane

and that to me... is all that matters

.....................................................

i just wanted your thoughts on this

if u do have esperience in rotations and control theory, could u provide some advice on this

[honest thorn]

for rodriges you need like a bunch of trig stuff, divisions, ect ect

matrix multiplication is pretty cheap compared to that

[torn talon]

this is not rodrigues, it is a varitation based off that concept

yeah but

once u find u hat and v hat

its just 13 ops or less and really just 2 to 3 if used with SIMD and FPU addition optimizations

should be competitive with matrices

i suspect at-least

..............

any other things i should look into

[honest thorn]

dont you still need tan?

[torn talon]

I actually wasn't aware of matrices or of this formula at all until a couple of days ago when i saw that i had already found a solution for u hat and v hat and just had to figure out how to implement it

But other than that, this badboy and most of my work has been completely indepndent and without any research

yeah

you do

but you only compute it twice or thrice ONCE fo ru hat and v hat

then, that just apply this formula with u and v hat for every point

.....................................

i mean we can just compute cos and sin to once

and then use those for the formula again and again

[honest thorn]

tan is a lot more expensive than matrix i think

also normalisation

[torn talon]

yeah but you only do it once

and normalization actually makes it faster

it is much much faster than computing the basis vectors and the right rotation matrix which u also do only one. That takes about 100+ ops. This, just 30

once

...........................................................................

honestly i think my real question has gone un-answered for the most part

[honest thorn]

also doesnt normalisation need a square root

[torn talon]

not really

[honest thorn]

yeah sorry im not an expert

[torn talon]

no no

i just wanted to ask if i should continue

do you think i should, or should i learn the basics first

like linear algebra, quaternions, and vectors like properly

that is the real question

[honest thorn]

yes for sure

[honest thorn]

its like 30 ops or something

btw

[torn talon]

so i should continue this project?

[honest thorn]

wait exactly 30 i just looked it up

[torn talon]

ohhh, i get what u are saying, i should learn the basics first

[torn talon]

yeah

[honest thorn]

probably

i don't think the methods are faster tbh

[torn talon]

yeah

they are in like 2 to 3 constrained scenarious

but i need to properly test

might be with heavy optimization

probs not best at everything

but like good for 2 to 3 applications

[honest thorn]

good luck tho!

[torn talon]

i do have a question

if u can answer, rn

like an opinion of yours

can i ask it

[honest thorn]

o

k

[torn talon]

so i know it sounds stupid, but i have been thinking about formaizing all of this and publishing online on Xarchive, I mean there is a lot more I have not talked about, including potential applications of this in deformation and gravity wells

particularly documenting all of my work

and also seeing within the next 2 months, if i can optimize and produce something meaningful

like, i only worked about 60 hours on everything, i think if i put in like 50 more, i can actually get some results and provide meaningful optimizations

.......................................................

if u know someone who i can contact about rotations, hit me up

[honest thorn]

If it's written up well and you find something why not

Also doesn't the second method exist already

[torn talon]

no

not as much as my literature research telle me

the formula exists yes

[honest thorn]

So what's the difference

[torn talon]

but the unit vector particularly u hat and v hat method does not for the most part

like how to find it

that is the key

cuz it uses up my previous 2 planar methods

and it treats 3d rotation not as projection but as planar rotations

[honest thorn]

What's the input output

[torn talon]

and at the very least, optimizing all of this, not done before at like a wide scale cuz everybody uses matrices

input output?

wdym

i mean u input u hat, v hat and theta and your point

and the output is just the updated point - after rotation

[honest thorn]

How do you get u hat v hat and theta tho

[torn talon]

by the planar rotation method i told u about

earlier

like ok wait

for u hat, u start of at (1,0,0

and then rotate this in the YZ plane by alpha

if the tilted plane is tilted in 2 directions, then u rotate the updated point by Beta the second tilt angle in the XZ plane

and u get u hat

for v hat, u start of at XY angle 90 and do all the aforementioned steps

boom, done

you do have to use like 2 tans, and maybe 1 or 2 atans in between depending on the tilted plane but yeah this is the gist of it

you can just use a vertical normalized lookup table for that

............................................

if u know someone else I can talk to about this, could u provide me their id or username or whatever @honest thorn

oh yeah and theta is just provided by angle we want to rotate by

@honest thorn could u help with that

[honest thorn]

very inaccurate???

[torn talon]

what?

no no

it is but i just want speed

that is all i care about here

and u can kind of interpolate between increments of 0.0 and 0.01 degrees and make it more accurate

it is faster than manual calculation using either the taylor series polynomials or other optimized formulae

that is what matters

[honest thorn]

then why not use the rotation for a rotation matrix

[torn talon]

???

[honest thorn]

why not

i mean

[torn talon]

cuz like the formula itself is faster

and lookup just speeds up the preparation thing

i mean it is still 30 vs 100 for the vector finding phase

so it does not really matter

plus, the setup costs dissolve to obsecurity over time as more points get added

.............................................................

ok it was nice talking to you, I am sure I wasted your time with this. Srr if I did, I just needed someone to talk to this about, but if u could just do the other thing too - like provide me any useful contacts that might help me with this, someone who is experienced in rotations, that would help out a ton, thanks again a lot. @honest thorn

[honest thorn]

nah sorry for wasting your time, u made me think

ty

[torn talon]

what about the contact thing

[subtle magnet]

I have no context but I see rotations and some difficulty and matrices. Usually most of the difficulty goes away when using quaternions.

Too long of a conversation for me to go back and understand but hopefully this helps.

[wise jetty]

launchers that are free

like tlauncher (malware, don't use)

[wispy solar]

ohh damn i didn’t know that was possible

[wise jetty]

so you can play mc but you can't connect to

a lot of servers because they don't allow "cracked" clients

[wispy solar]

Yea makes sense

[wise jetty]

you can change ur username and such to anything but like yeah

they dont allow them

anyway, since you have genuine mc

download modrinth launcher

sign in and all

[wispy solar]

yess alr thanks for telling me🙏

[wise jetty]

pretty good tool for modpacks and such, even if you don't use modpacks just download the fabulously optimised modpack

it'll like quadruple ur fps

and ur pc will thank u

[wispy solar]

well makes sense

[wise jetty]

mhm

[wispy solar]

:))

[wise jetty]

if u want shaders, like, ur gonna have to fisrt

unlink the instance (which isn't hard js go to settings)

(the instance is that particular like, uh, launch)

and then you'll just have to go to "browse content" (aka search mods) and go to shaders

and pick one you like

[wispy solar]

🙏 🙏 🙏 alrr

[wise jetty]

the rest is simple it's in minecraft's video settings

ye

prolly tutorials for this too check em out

anyway im gonna go eep now, cya

[wispy solar]

yep true I will

Is there a formula I could use to calculate the radius of a circle needed for a staircase to come out at the same spot

Bro that makes no sense.... OKAY LOOK

I dont have image perms...

[solar hawk]

#chill

[shadow mauve]

No it does

Like a spiral staircase?

[nimble oak]

ye

Im in mc and im trying to make a spiral staircase that has a certain height seperating it

[shadow mauve]

Wait idk if thats possible without weird curves

[nimble oak]

I wanted 15 blocks but I dont think thats achievable

[shadow mauve]

You can loop but it wont be the same dieection

[nimble oak]

yeah so ima just do more than 15

[shadow mauve]

You’d be turned 180

[versed steeple]

I really like all "X are Y, but not all Y are X" explanations.

"All strictly dominant strategies are the best strategies, but not all of the best strategies are strictly dominant," kind of carried me.

For example, if I (and an opponent) were to pick a point from 1-10 and whoever staked the most territory from the edges to the closest claim, then picking 3 doesn't dominate 2 but it is better.

I almost like to think of it as a matter of game balance. A strategy dominates when it is better in every situation, and thus needs to be nerfed (so every strategy remains useful).

Although you might need to replace strategies with something like classes in TF2.

[gleaming goblet]

question, after learning discrete math, what should I study next? options, algorithms, linear algebra, advance probability and statistics?

[latent edge]

Linear algebra

[gleaming goblet]

ty

but why? the truth is, I'm undecided between algorithms and linear algebra

[latent edge]

Because linear algebra is infinitely more useful imo

You'll use it in algorithms anyways

So why not get a starter on it

[gleaming goblet]

gotcha gotcha, tysm for the advice, I was thinking of using the book Linear Algebra Done Right by Sheldon Axler to study a little more in-depth

[latent edge]

Make sure you learn determinants properly before reading Axler since it's known for doing such a horrible job

[foggy meadow]

@zealous garden Do you want to hear about tree thing?

Well dang.

🌳

One day someone will help me with this idea, but for now it's just me on this island alone.

[inland raft]

guys has anyone here tried salvia?

[candid storm]

don't bro

it ain't safe

[inland raft]

it is preety safe

[candid storm]

oh then u did some trash

cuz that shit takes completely over

[inland raft]

yeah that's the beauty of it

[candid storm]

ig... depends what u see

[vivid halo]

no you're not doing it right if you're not being a complete fucking moron about it

[candid storm]

my homie was being chased by a shark

[inland raft]

yeah

thats so fun

[candid storm]

i was the shark

[candid storm]

i chased him to his class

and I was staring at him through the window

and he started to cry... the professor kicked him out

[vivid halo]

[inland raft]

i guess the main reason why i want to take it is to let my mind run wild

for once

alcohol isnt enough

[candid storm]

no no it's fkn stupid

[vivid halo]

not as wild as Mister Window over here

[candid storm]

lmao

everyone turned to zippers for me

and I took off in a full sprint behind the classroom bungalows

[inland raft]

i just want to have this otherworldly experience end never be the same again

zippers sound mid

[candid storm]

people are clothes

is what my mind was telling me

[inland raft]

yeah thats kinda meh

[candid storm]

in other words... there's people that wear us as clothes

it was just my mind accepting that

try something else for what u are looking for

[inland raft]

alr

like what

[candid storm]

like maybe meditation

[inland raft]

hm

[candid storm]

but salvia won't introduce u to nothing but fears u can't accept

[inland raft]

could work

but its harder

to master meditation

than jus ttaking something

i guess it is more rewarding, though

[candid storm]

and it's real

unlike a hallucination

[inland raft]

who says salvia sightings arent real

salvia and meditation is both make-believe

tricking of the brain

its jsut 2 different methods

[candid storm]

our fears can never be real only overcame

[inland raft]

wdym

[candid storm]

it's an illusion like a dirty trick into bringing something to life

[inland raft]

yes

both meditation and salvia

[candid storm]

well mediation can help guide the body

into its natural state

[inland raft]

the purpose of meditation is tricking your brain into thinking that everything is ok

[inland raft]

so you re saying that being zen is the natural state

of the mind

[candid storm]

hmmm... maybe this is where my opinion really kicks in, it's just a belief of mine that it is. Confusion is caused to only perplex us or destabilize.

[inland raft]

yeah but the "zen" isnt really found in the universe

i think zen comes from accepting that the world is chaotic

[candid storm]

because people look for the universe out there when the light pours in

[inland raft]

and learning to live with that chaos

[candid storm]

that's a great point too

[inland raft]

what does this mean

[candid storm]

your eye only receives light

[inland raft]

hm

ok

so you would say that meditation is the best way to create a strong mind

or?

[candid storm]

I would say it's like eating ur vegetables and drinking water, vital, but not the whole equation.

and drugs

are junk food

and soda

fun until u get diabetes

[inland raft]

at the end of the day

there arent any humans who have mastered their mind

so me wanting this is kinda unrealistic

still

i do wish to get as close as possible

somehow

[candid storm]

i encourage u... thanks for the chat gtg

[inland raft]

thank you

goodbye

[feral yacht]

it was older edition

[near fox]

How to master your mind?

[inland raft]

this is what i have been trying to find out for man yyears

i dont know the answer yet

[near fox]

Okay

What is mind mastering

[inland raft]

it seems that there are some periods in which i am close

[near fox]

?

[inland raft]

but then it all goes away

[inland raft]

basically you control your own thoughts, feelings

[near fox]

Oh damn

[inland raft]

the words of others dont bother you anymore

you reach a zen state

peace

[near fox]

I can control my thoughts but I can't control my feelings

If I'm angry.. I remain angry

[inland raft]

yes

[near fox]

Anger is the most powerful emotion in me

[inland raft]

you have to reach a state in which nothing bothers you anymore

in which you are the master

[near fox]

This is not possible

[inland raft]

you control everything

[inland raft]

it is

it all depends on your persepctive

[near fox]

I have job, rent, girlfriend, parents, friends.. these things bother me

[inland raft]

you choose to be angry

angry isnt a natural state

[inland raft]

good

[near fox]

I'm angry for about 15 minutes then I'm calm

[inland raft]

thats preety good

[near fox]

But I can't control everything

[inland raft]

do you feel like you have a strong mind?

[near fox]

Yes I believe in that

[inland raft]

great

i dont

this is what im working on

i think i will try meditation

because i knoiw

that my mind is capable of a lot of things

but im actively restricting it

for some reason

becuase im afraid

or ashamed

i need to get rid of the barriers

[inland raft]

in general, a mastered mind isnt influenced by the outside

you notice the outside

and you decide

how you want to feel

about it

[near fox]

Damn..

Nah I can't do that

If something pisses me off

It will

[inland raft]

yeah thats a sign of a weak mind

[near fox]

I have full control over anxiety though

Just not anger

[inland raft]

interesting

i dont

maybe you are even better than me

[near fox]

Another superpower I have is being comfortable alone

With no smartphone or other stimulation

[inland raft]

yes thats good

but you said you had a girlfriend

so

[near fox]

Yes

[inland raft]

thers always someone yo ucan turn to

for support

who loves you

[near fox]

True

[inland raft]

see?

this is where we differ

in times of trouble

i dont have such support

i think a girldfirend is a huge plus

yes, sometimes it can be annoying/ a lot of work

but it is also rewarding

so i think it's worth it

it definitely helps in the journey of having a strong mind

[near fox]

It is

I've spent years in search of gf and the grind definitely paid off 10x back

[inland raft]

yes

good for you

1 day

i will also be satisfied

although im trying not to make it my primary goal

because then there s a risk to get distroyed

i wish to view it

[near fox]

But ur right about developing a strong mind. It's a good thing

[inland raft]

as just an added bonus

thanks

[inland raft]

i think its the most important thing

i guess when i said that i wanted to try stuff like salvia

i wanted to take the easy way out

but true mastery isnt achieved quickly

[near fox]

Salvia isn't a good drug to do

[inland raft]

instead i think i have to work on it a lot

yeah

i had hoped that it somehow opens my mind

but i guess it has more negative effects than positive ones

[near fox]

If u want to open your mind you need shrooms or lsd

@inland raft

Those will reveal your inner world to you

[inland raft]

thank you

[near fox]

Salvia is a scary traumatizing drug

[inland raft]

so i've heard

[near fox]

It's not even a psychedelic. It's a deliriant

[inland raft]

ok

[inland raft]

then i will look for those

and start meditation

it's such a pity that they are illegal

[near fox]

@inland raft don't do big doses

Start small

See how u feel

[inland raft]

good advice

[near fox]

@inland raft if u have a bad trip on lsd or shrooms and u manage to stay strong and calm then that's a big achievement

[inland raft]

so you're saying that this should be my goal

nah actually the goal would be to stay strong while on salvia

i think if i can do that it means i've mastered the mind

[near fox]

That would take an insane amount of self control

[inland raft]

so this is what i should strive towards

but first i will try meditating

and if i can get my hands on some shrooms or lsd

i will give it a go

[near fox]

@inland raft become very good at handling anxiety

That's your first step

[inland raft]

yeah but how

[near fox]

I've managed to turn off anxiety whenever it happens for me

[zealous garden]

how do I control my anxiety
just don't have it, lol

https://tenor.com/view/mujikcboro-seriymujik-gif-24361533

[inland raft]

yeah thats impressive

i dont know how to do it

like

i have anxiety

in the most normal circumstances

like

in everyday scenarios

[near fox]

I don't have it because I've got a hormonal error@inland raft

Whenever my body is supposed to release adrenaline, it releases feel good hormones instead

I feel a warm high for a brief moment that completely turns off any anxiety

An anxiety kind of adrenaline.. not anger adrenaline

[solid yarrow]

Oh I didn't see that sorry

[supple crescent]

anybody knows where to get calculus 1 questions and answers

[dim ice]

Hey do you ever want to become a mathematiciam

[vale flint]

I suppose that would be nice yeah

[placid wave]

highly recommend learning some programming

or you can go into the teaching route and get a masters in education

[vale flint]

Yeah,I know html, css, python, r, git, and java

Teaching is not for me

[placid wave]

try adding a minor in cs if you want to go that route, however we have no clue how ai will take over programming

or you can go into some sort of finance related field, accounting, etc

i'm a junior getting my B.C. mathematics & computer science combined degree, and planning to maybe go into some sort of finance depending on how many programming jobs are still available by the time i graduate

[latent edge]

Hi foxy

[vale flint]

I've already graduated, so...

[placid wave]

oh ok nvm i thought i read that you're still earning your BS

maybe go back to school for a masters program?

[rough summit]

Minors don’t even add onto your degree

At least in Canada

They aren’t displayed on your degree, only on your transcript

[distant mason]

Minors are a waste of time IMO. They dont do much for you. They still cost money, require time and effort, but have basically no real benefit. Whatever youd learn in a minor course, youre better off just self researching.

[ocean harbor]

😭🥀

[placid wave]

wtf that's weird

[placid wave]

careers cooked🥀

overqualified for mcdonald's underqualified for wendy's ahh situation

[ocean harbor]

i was a cs major and quit that bc of ai. it is literally replacing every programming language and most people just writing prompts

which takes about 2 minutes instead of 2 weeks LMFAO

[placid wave]

right, my mom works as a software developer and she has no clue how long she'll still have a job

however it's a huge company so idk

even then they're writing more prompts for claude and testing lines rather than writing code

so the entire workday is mostly meetings

[ocean harbor]

yea

also, if your mom already had a software developer before, then that makes sense honestly, because it wasn’t as cooked as we are today lmao

[placid wave]

well yeah shes been working in the same company for ~20 years so it was nowhere close to what it is now

wasnt even developed actually

autocorrect was barely out atp 😭

[ocean harbor]

yeah that makes sense

its crazy how time flies fr

[pure haven]

if you are getting replaced by AI then you were never a competitive engineer to begin with and prob wouldn't have gotten a job anyways

[ocean harbor]

I don’t know who you’re talking to, but I was never replaced by AI when I was into programming stuff ¯_(ツ)_/¯

[placid wave]

well ai hasn't gotten far enough yet to replace all programmers

but it'll get there

or very close

[pure haven]

if you quit CS because of AI then you effectively were

AI is good but it is nowhere near "replacing every programming language"

that's just false

come on

don;'t fall for the hype

[ocean harbor]

No, people literally put zero effort into their code, and it was a pain to manage that. I was into programming way before AI was even a thing lol

[pure haven]

Yea people put zero effort into their code and that is a problem

[placid wave]

it'll get pretty damn close

[pure haven]

AI is not going to replace all programmers / programming languages

there will just be more slop code

we will need engineers still

[placid wave]

that's what testers are for

[pure haven]

and engineers?

whos going to write the fixes

quitting CS just because of AI is really silly imo

[ocean harbor]

I mean if you literally buy a paid subscription, you will definitely fix the issue no?

[placid wave]

that doesn't mean it won't replace any programmers

[pure haven]

not necessarily

you're acting like chatgpt has the capacity to replace

the entire workforce of a large company

do you know how complex large codebases are

[placid wave]

claude has effectively replaced at least 3-4 departments that i know of in my moms company

[pure haven]

i've seen so much junk code and security issues online since the dawn of AI

people who believe the AI replacing CS narrative are just buying into a lie imo

[ocean harbor]

Not only because of that but job market is also cooked

They need 10+ years of experience

[pure haven]

thats a valid point i guess

entry level job market is pretty bad

[fair yoke]

I think cs tho can be definitely used in some other fields

Idk

[calm fulcrum]

ok i did

what am i supposed to find here

[dreamy viper]

i have a question, but idk if it would fall under help, its also kind dumb

[sterile fable]

Can anyone brainstorm me on agritech ideations?

[sterile fable]

Go ahead

[dreamy viper]

ok so im in a dumb argument with a friend. i cant send the images into this chat

dont laugh if this is a dumb question but a rhombus isnt considered a cylinder right?

its level curves are all congruent along one axis, so its a cylinder

this is their point that it is

[verbal quest]

I just take it as a textual tic

[old oak]

It's a conversation starter

[old mural]

are there number systems where arithmetic operations between infinities are all defined? would it even be useful?

[old oak]

The simplest example would probably be the extended real line, which allows some arithmetic operations where infinities are involved.

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

You can't fully extend the real number arithmetic to infinite values in a way that would be consistent and intuitively make sense.

[old mural]

ok so that wasnt much more than riemann sphere

[old oak]

Yep

If you go in the direction of cardinality (distinguishing between infinities of various "sizes"), then you do have cardinal and ordinal arithmetic.

But only a bit of that (mostly what pertains to countability) is broadly useful, past that I'd call it a bit more niche (if very fun)

Extended reals are very useful in subjects such as measure theory (and they show up when discussing limits in calculus, although often not framed as "extended reals")

Oh, there's also nonstandard analysis which gives a general rigorous framing to the concepts of "infinitely small" and "infinitely large" numbers: https://en.wikipedia.org/wiki/Nonstandard_analysis

As a fun consequence this allows the practice of treating dy/dx as a fraction to make actual sense.

[plush idol]

it'

it's a little different since there's 2 infinities

so you don't allow dividing by 0 still

extended real line is more useful in eg measure theory and analysis, riemann sphere is more useful in complex analysis and projective geometry

[plush idol]

meh. it's the standard part of a fraction. That doesn't seem much better to me than the limit of a fraction.

I've never really joined the nonstandard analysis hype train. It's a decent idea, but law of conservation of difficulty applies

[vivid halo]

this is incredibly useful if you are doing differential geometry the way algebraic geometers tend to think about things

although this approach is not really so nonstandard from this perspective and one usually uses other names like synthetic differential geometry or whatever

[plush idol]

Algebraic geometry approach to analysis is like R[x]/<x^2> right

[vivid halo]

yeah exactly

very very useful to have this in differential geometry for obvious reasons

[old oak]

I'm not particularly recommending nonstandard analysis, it's nonstandard for a reason and apparently tends to be more trouble than its worth

[vivid halo]

kinda like geometric algebra lmao

[lethal sphinx]

hii guys

[proven fulcrum]

Greetings friends, how do you do?
I'm looking for intellectual discourse, sharing information your excited about and studied and so will I.
Intelligent people without logical fallacies only.

[lethal sphinx]

i am good what about you

[vast wraith]

you don’t want your basic analysis to depend on arbitrary non-principal ultrafilters?

[inland hornet]

non-standard geometric algebra

[plush idol]

yeah, part of the point of my comment though was that even in NSA, it's not a fraction

[sterile fable]

With that logic a square or triangle too becomes a cylinder

And if like every consistent cross section is a cylinder then we are just talking about prism?

[agile geyser]

Sorry for late reply

[slim cairn]

The most interesting one is the surreals. Somehow big enough to contain the average discord mod

[storm sage]

it has some elegant proofs though

[junior veldt]

Why’s that

[storm sage]

bolzano–weierstrass ends up being a one-liner which is cute

[vivid halo]

well for one thing it's very useful to have representing objects for things like tangent bundles

If you think of T=Spec(R[x]/(x^2)) as a square-zero thickening of a point then this represents tangent bundles in the sense that TX=Map(T,X)

replace x^2 with x^n and the same is true for jet bundles

[storm sage]

there's also a cute construction of lebesgue measure on [0,1] in nonstandard analysis: let N be infinite, consider the set T = {0, 1/N, 2/N, ..., (N-1)/N}, the measure of A is just the number of times it intersects T (or gets infinitesimally close), divided by N, so lebesgue measure is just an infinite version of counting measure

[proven fulcrum]

Semantic interpretations of good, reach N^2 complexity

[storm sage]

I mean... to be fair this weaker than the axiom of choice, you don't really need to invoke an ultrafilter if you accept the axiom of choice

[vast wraith]

yeah i just think it’s a funny construction

[storm sage]

yea

no doubt

[inland hornet]

wth is n^2

[storm sage]

Hm, is every hyperreal field isomorphic to some ultrapower of R?

[proven fulcrum]

Category error

[storm sage]

Why?

by the Löwenheim-Skolem theorem you can simply take elementary extensions countably many times to get an elementary extension of the real field (equipped with all its structure) of cofinality ω, which is therefore not realized as an ultrapower.
Hm so I guess the answer is no, according to Joel David Hamkins

https://mathoverflow.net/questions/500094/is-an-ultrapower-essential-for-defining-the-hyperreals

[old oak]

I mean, I love me some arbitrary non-principal ultrafilters, I just don't find them particularly helpful for doing my analysis.

[vast wraith]

[old oak]

If you're doing analysis without the axiom of choice you have bigger problems than ultrafilters

I like my unions of countably many countable sets to be countable, thank you very much.

[junior veldt]

yeah especially since you can't describe one on N afaik

[storm sage]

yea although assuming CH, I think all constructions using ultrafilters on N are isomorphic

it's to be expected you can't describe a canonical one explicitly tho bc it's basically a way to do (a weaker version of) the axiom of choice

[dusky schooner]

do you think that a group is brown

[unborn trellis]

yes, the brown group

[old oak]

It's brown

[unborn trellis]

Thm. There exists a brown group.
There are no green groups.

[grim torrent]

The Brown Group refers to several distinct entities, with the most common being a full-service real estate development and investment company focused on land use, construction, and property management. They typically handle the entire lifecycle of residential and commercial projects.

I'm actually a first-year graduate student, in neuroscience; I graduated with a math degree last year

That sounds very cool

I've heard that intelligence if somewhat genetically inherited from parents

I really don't wanna believe in that because my dad isn't the smartest person in the world and my mom sucks at math

[quick beacon]

Somewhat, but like, I'd say in my experience it's mostly nurture. Both my parents were high school dropouts and neither of them are any good at math

[near fox]

So its possible to become way smarter than your parents combined?

I really hope im not limited by my genetics lmao

that would suck

Guys i know this is a long shot, but does anyone know/can be an IB AI HL tutor for like 20 CHF/EUR/USD an hour? I know its a long shot but i found a physics tutor for like 20 euro an hour for Physics SL and im m26 so i have about a month until my math exams. Thanks!

martsh to neurosci

so tuff

[haughty dove]

Any good resources for convex optimization

[sharp mulch]

What sort of resources

Books?

[storm sage]

sure

the thing to realize is that genetics is usually a statistical phenomenon

there might be general trends across a population but you can't conclude anything about your specific abilities

it's not helpful to try, unless you think you might have a genetic disease that should be looked at

Intelligence isn’t really something cleanly quantified by a linear order.

Maybe a partial order at best.

[storm sage]

It is strange though that skill across a wide variety of domains seems to be roughly correlated, I wonder what that says about the organization of our brains

I would've expected them to be mostly independent

[calm fulcrum]

it's like trying to order R^omega lol

[brittle jasper]

Don't want to comment too much on it since it borders on server rules but
The problem isn't intelligence or any of its ordering. The problem is assigning value to it.

[wooden falcon]

My thinking is that what makes up peoples’ brains and intelligence is a mosaic of characteristics (moreover it’s mutable). So then we see quality in certain characteristics manifesting as skill in disciplines most strongly rewarding those characteristics.

No clue what precisely those characteristics would look like though ofc.

Does anyone have any recommendations of good books to use to self teach maths post A level? I would like to learn a bit more at a higher level

Thanks

I didnt have that chanel originally im a dummy

[solid yarrow]

And I summon @latent edge

Ehh could have worked
