[velvet dagger]

How so ryc?

[deep mango]

maybe for some proofs....

for a lot of math proofs the hard part is having the idea in the first place

[hidden bone]

I used to have that issue

But then again

I have only done set theory and logic

So haven’t reached the hard stuff yet

[deep mango]

sometimes if really good opportunities are laid out in front of you, you aren't able to get yourself to say no to them even if saying no to them is the best course of action for your personal goals

i am who i am now because no one was setting up dominos for me to knock down toward a math phd

no one in my family has any clue what academia or STEM is about

i would not be who i am if i didn't have to figure some stuff out and pry open some doors myself

obviously at some point this could backfire and it's like, oh, i'm stuck and i can't move forward and maybe i could have had i had a better set of resources from the start

[velvet dagger]

That's possible but I also don't necessarily think this path is like, "the only" one that could've worked if that makes sense? If you're locally doing what feels right you're probably gonna somehow end up in a good spot

[hidden bone]

also

Another question

[velvet dagger]

I applied ED to Penn and would've gone there if they ended up pulling through with the aid

[hidden bone]

How hard was college for y’all

[velvet dagger]

I was actually in the school of engineering and applied science there!

[hidden bone]

Where did u go

[deep mango]

uh, very very hard by the end

[velvet dagger]

Chances are I would've never done the math major, I would've done smth like CS or chemical engineering or smth like that

[deep mango]

i was supposed to do chemistry, so i get what you mean

[velvet dagger]

But I'm pretty certain that if I went down that path, one way or another I would've been happy. Obviously even if I'm giving advantages the onus is on the kid

[deep mango]

sure

i don't think this is the way that everyone looks at their life trajectories though

[velvet dagger]

I could send them to a great school but they have to be the ones who wanna work in school. The college counselor being able to give individual attention and turn lotteries into games with reasonable odds is an advantage but if they decide you know what? I wanna drive a truck. Then they can do that, and then my way of helping is to get them started without debt in trucking

[hidden bone]

Are y’all happy u did a math major

[velvet dagger]

I guess my view is that success in life is something that's both a function of your choices and a function of... random shit

[deep mango]

but there are social/cultural/personal costs which come with something like "i'm going to drop out of school and drive a truck" that are being abstracted away here

[velvet dagger]

And if that random shit just stops you dead in your tracks it's like well... that kinda sucked

[deep mango]

i'm very happy with it. it was a lot of work but i enjoyed all of it a lot.

[hidden bone]

How many hours a week

[deep mango]

varied a lot

[hidden bone]

Today I studied the whole day

[deep mango]

sometimes it was 10 or so hours a week, sometimes it was 90

[hidden bone]

Only 10

[velvet dagger]

It's possible on accident it leads to a path that would've been better but it's also possible, in fact more likely, that it just makes your life garbage for a while with no real payout. If you can bend things in your favor sometimes without being immoral... Could work

[hidden bone]

sometimes

Bruh

[deep mango]

usually it was around 40 hours a week (just a job)

[hidden bone]

I also think I learn slower in math lol

[deep mango]

you probably don't, math takes a lot of time to learn and get used to (proof based math)

[velvet dagger]

re the costs: I mean I guess in principle there could be pressure but as far as I'm concerned if I have kids I'll communicate to them that, hey success comes in many forms

[hidden bone]

Idk

[velvet dagger]

Pursue your success

[hidden bone]

I grinded 8hrs today

For a test on Wednesday

[velvet dagger]

And my job as a parent is to do my part to make your goals/dreams a reality

[hidden bone]

@deep mango did u go to Berkeley

[deep mango]

i feel like as a kid i rebelled against my parents being like "you should do what you want and enjoy the moment, it's not good to plan too far ahead" mentality and this is what led me to be very structured and ambitious

[velvet dagger]

It's possible I look at things too much as a success/failure mindset, in particular I'm very risk/failure averse relative to other people

[deep mango]

maybe that's why i think my parents had a good strategy

[hidden bone]

I agree with enjoying the moment

[deep mango]

yes

[velvet dagger]

But I think there's some merit to that mindset

[hidden bone]

What’s the intro to proofs class there

[deep mango]

there is none

or

[hidden bone]

What

[deep mango]

i guess there is one

but it's just discrete math

and linear algebra

both show you how to write proofs

[velvet dagger]

And that for most people, reducing barriers to success and having it such that the cards are in your favor is a good thing

[deep mango]

idk, i usually opt to make things more difficult for myself when i can because i'm not doing the thing for whatever the thing does, i'm doing the thing for personal growth

[hidden bone]

I also realized something in college

U have to actually pay attention

In lectures

[vagrant kestrel]

D:

[hidden bone]

Like in HS I never paid attention to class

[deep mango]

[hidden bone]

And used YouTube to survive

But like YouTube don’t help anymore

[deep mango]

youtube can still help if you find the right channels

there's a lot of advanced math on youtube now

since covid

[hidden bone]

Really

What are good proof channels

[deep mango]

uhhh

[velvet dagger]

Yeah I tend not to look at things that way. Like... idk for me a lot of the point of personal growth is that it helps you "enjoy life" rather than as an end in itself?

[deep mango]

richard borcherds is like the best

but is also for more advanced classes

[hidden bone]

Is he math sorcerer

[deep mango]

(abstract algebra and stuff)

[deep mango]

for me enjoying life and undergoing difficulty are pretty tightly knit

[hidden bone]

Also did y’all do competition math

[deep mango]

if you drive me to the top of a hill to show me a view then i don't care about it nearly as much as if i hike up the hill

[deep mango]

i did the putnam exam all 4 years but i never cared much about doing well on it

in high school i got to the AIME twice, did terribly on it

[velvet dagger]

Hmmm, for me it depends. Low stakes challenges that are about... idk if I should say strategy but are somehow mental

[deep mango]

competition math is a meme

[velvet dagger]

Are the types of challenges I vibe with

[hidden bone]

Does it help for college

Competition math

[deep mango]

not really

[velvet dagger]

If it's a matter of pure grit or if it's actually a high stakes challenge, like failure comes with a nasty cost

[deep mango]

maybe if you do like

combinatorics classes

[velvet dagger]

Then I think I'd rather have it smooth

[deep mango]

alright well

careful if you want to project that onto your kids

i don't think what i'm saying is the norm but i also don't think it's terribly uncommon

[velvet dagger]

I'd wager people find challenges that are purely a matter of grit more rewarding than I do

[deep mango]

(although it's possible when people say things like this, they're just coping)

[hidden bone]

Well if I have kids I’m forcing them into competition math or science

Makes u a better problem solver and test taker

Imo

[velvet dagger]

But I'd say when it comes to high vs low stakes most people are hard on my end

[velvet dagger]

Actually the opposite of coping, at least as far as low vs high stakes

[deep mango]

what do you mean

[velvet dagger]

I think it's much easier to be okay with "high stakes" risk vs... actually high stakes risk

So I'd wager a lot of people who enjoy difficulty in the sense of, failure comes with a price

That price isn't as high as could be

[hidden bone]

@deep mango do u know anyone who never studied for anything in math or stem and did well

[velvet dagger]

You're sorta confident that you can bounce back from failure and things will be okay

[deep mango]

i really have very little idea of what you mean by failure or stakes of stuff

i don't have a measure for that

i just do stuff and having to deal with tough situations is fun

[hidden bone]

I’m failing rn

[velvet dagger]

I guess as an example

[hidden bone]

Lol

I have a C in Econ

[velvet dagger]

When my dad moved from NY to Texas to start a business that was a gamble

[deep mango]

hmm, how about literally everyone i'm related to

ok not all of them do well

[hidden bone]

I mean in college

[velvet dagger]

It's a big move and a risk but I don't think it was a thrilling one

[deep mango]

but most of them

[hidden bone]

Like went to college

[velvet dagger]

Because the cost of failure is, he's in debt probably for the rest of his life

[hidden bone]

Aced every math class

Never studied

[velvet dagger]

When that's the reality that's facing you

[deep mango]

oh

i see

[velvet dagger]

Difficulty becomes way less appealing

[deep mango]

i thought you meant "never studied any math or science"

not "never studied FOR math or science"

lol

no, i do not know anyone who never had to study

everyone met their cap at some point

where they couldn't rely on natural ability

sometimes it took a while to find that cap

the harder they fall, etc etc

[hidden bone]

I mean also in college how do u retain everything

For like math stuff

[deep mango]

you dont

you forget some stuff after your exams

and then later you might need to know it again

so you look it up and it comes back really quickly

[leaden skiff]

well, if you actually understood it then it comes back easier than if you blindly memorized it

[deep mango]

yeah

[leaden skiff]

I don't think I could remember any of the Stat formulas I learned in school even if I looked them up cause I never understood them 😔

[deep mango]

[real lantern]

Has anyone done the mit ocw 6.042j math for cs? Not sure which one to do, the 2016 or 2010 because the 2010 has full lectures.

[limber perch]

6.042 is a nice course

it’s basically an intro to proofs class for the cs majors there

the ocw year shouldn’t really matter

[vale dawn]

hey if we have to square a number like if we want to square 100
we can find the sum of first 100 odd numbers which is equal to that but why this thing happens
is this any sequence or series

[vale dawn]

and for even

[leaden torrent]

if youre familiar with induction, try to prove it.

[vale dawn]

is there any thing

[vale dawn]

ohh its from the induction

[leaden torrent]

weird phrasing

there are many reasons this identity is true, from geometric to combinatorial

but its good induction practice as well

[vale dawn]

ok thanks

👍

[hazy fiber]

if you project a sphere onto a tangent plane like this
https://en.wikipedia.org/wiki/Orthographic_map_projection
is the result a full hemisphere or is it off by some infinitesimally small amount
like, say true north is at 0 degrees latitude; if you do a projection like this at the equator, is the northernmost point 0° or is it like 0.000000000001°

apologies if this isn't relevant to anything, just curious

[untold sapphire]

it would contain the northernmost and southernmost point

[hazy fiber]

cool

i unironically havent studied for a school exam in forever, one of the reasons why my grades were very wonky

studying important kids

on the other hand i had plenty of time to study for things like the math gre

so i did

[odd narwhal]

Tips for studying for the GRE? Everyone says just review but my calc classes were very non-computational so I don't have that experience

[atomic cypress]

just practice integrals and series from single amd multi variable

and know basic definitions and concepts in analysis, topology, algebra

[bronze pelican]

the best tip is to have yourGRE cancelled because of the pandemic and not have to submit a score to grad schools 😎

[narrow rock]

don't do the GRE

[glad grove]

If I cry hard enough on the GRE will they let me pass

[narrow rock]

don't do the GRE

[glad grove]

nobody wants to do the GRE

[narrow rock]

don't do the GRE

[cold needle]

i hope i don't have to do the gre

[limber thunder]

there's also mock GRE sheets you can actually use to practice, that's your best bet for these kinda tests

lots of repetition

hopefully you won't have to do it tho

[odd narwhal]

Problem is there aren't a lot of previous GREs

So you can run out of official material p quickly

[narrow rock]

don't do the GRE

[atomic cypress]

don't do the GRE

[sick burrow]

when should I start studying for the GRE

I'm currently at the start of my Junior year of undergrad

[narrow rock]

don't do the GRE

[jovial ember]

I’m gonna do the GRE

I’m gonna do it 1000000000x times

I’m gonna give ETS 3 billion kajillion dollars

[bronze pelican]

What does ETS do with the money

[eager crescent]

They buy tomatoes to throw at people

[languid gyro]

Fuck ETS

[limber perch]

the ETS is owned by Pearson

You know Hindi?

Google Translator exists.

[toxic schooner]

this is some lore of the server

which can be explained in a single sentence

[pale orchid]

what is chand mara

[toxic schooner]

Chand means moon

i think its a slang-y way to say gand mara

[gentle bay]

For further explanation of this you are recommend to use Google Translator.

[weary garnet]

are there cases where you can't express something without parametric equations or are parametrics just to make things neater and easier?

[bronze pelican]

nMizzoid

[sick burrow]

what do you mean "express something without parametrics"

[weary garnet]

can any parametric curve be expressed in terms of x and y or whatever variables without the parameter

[leaden torrent]

sure, but your expression might be a complicated piecewise mess of relations

parametrizations are often much simpler

[leaden skiff]

is there any situation where the parametric is really ugly/complicated, but the direct equation isnt?

[sick burrow]

This isn't maybe the best example, but I'd rather express a circle by the relation x^2 + y^2 = r^2 than with a parametric

Or how about this. Imagine a set of nested circles with each integer radius from 1 to n, with a vertical line connecting all of them into one path. That's easy to describe with "sqrt(x^2 + y^2) is an integer, or x=0" but i really do not want to parameterize it.

You could probably think of more annoying examples if you tried

[meager sonnet]

Oh hey Mirza is back

[leaden skiff]

i think $(r\cos t, r\sin t)$ is as good if not better imo

[fathom swallow]

Ninja

Ninja

[wild lantern]

It seems like you could always make a parametric equation of a curve messy.

[leaden skiff]

imo the parametric is always as messy or less

i cant think of many situations where it's worse

[wild lantern]

Like rather than (cost,sint) it seems like you could have (cos(t(u)),sin(t(u))) where t(u) is some nasty function that still lets you plot the same curve as (cost sint).

Oops I meant rcost, rsint.

[leaden skiff]

there is always a parametric equation that can model a curve better than or as good as any "normal" equation

what's the word for a "normal" equation again?

like y = f(x) or f(x,y) = C

Is it weird to feel like a genius when you're buzzed on caffeine?

[bronze wren]

When graphing an equation f(x) (co domain) is always denoted by y so I don’t know what you’re talking about

[leaden skiff]

you mean f(x,y) = c?

[bronze wren]

F(x) = y

Y is literally f(x) that’s how functions work

[leaden skiff]

what are you not sure about

like what don't you understand about what i said?

[bronze wren]

Functions where y isn’t f(x) non-“normal” functions if you will

I don’t think they exist lol

[leaden skiff]

no i meant a "normal equation for a curve"

[bronze wren]

Excuse my nieveness btw

[leaden skiff]

cause theres ways to describe curves that aren't in the form y = f(x)

[bronze wren]

Huh

[leaden skiff]

$\vec{r}(t) = (x(t), y(t))$

[fathom swallow]

Ninja

[leaden skiff]

that's a parametric equation of a curve

[bronze wren]

Shit idk what that is

[leaden skiff]

it's not of the form y = f(x), although sometimes it can be reduced to one

[leaden skiff]

or for a simpler example $x^2 + y^2 = R^2$

[fathom swallow]

Ninja

[leaden skiff]

that's a circle, but it's not of the form y = f(x)

[bronze wren]

Ohhhhh

I gotcha

[leaden skiff]

btw the co domain isn't always y, sometimes the domain is t, and the co domain is x for example

[bronze wren]

Yeah I used why for an instance

*y

[bronze wren]

Is it called “a function of time”?

Ones where domain is t

[leaden skiff]

that would be, yes

[zinc lily]

Yes, Mathematics server is the most friendly one I hv been.

3. To confuse people who thinks that badges should be related to the text of the message

[frank abyss]

Guys when you see this

what do u understand frm it?

im so confused as to what its saying

whats the (1) and (0)

[fast ivy]

What's the context exactly?

[frank abyss]

My textbook says the following:

The Historical Model, it is assumed that the correlation coefficients in the previous
period will give the best estimate of the correlation coefficients in the future.
So the correlation coefficient matrix keeps the same as the previous period. The
idea of Historical Model is very simple, we use the historical matrix in this study
as a benchmark against with other models can be evaluated.

[fast ivy]

I don't know if that tells us much

Could you take a screenshot or something?

[frank abyss]

ok

[sonic sentinel]

guys how do i submit my math homework it says to "upload file" i think we have to use the binomial theorem here

[leaden torrent]

sorry, thats not possible in general as the space of all math homework does not surject into online homework submission platforms

in other words, uploading homework is not epic

[vast surge]

The fact that it's not surjective doesn't mean that it's not an epimorphism; consider the category of rings.

[leaden torrent]

sorry bub, the category of homework is concrete

And the category of rings isn't?

[high rivet]

Is getting a 1390 on my SAT good if I was only 15?

[distant vortex]

Sure, getting a 1600 at 15 would be even better

[pale orchid]

you should just look at what your target unis are asking for

[distant vortex]

More specifically, good for what goal?

Yeah, I don't think unis will take your age into account that much. The score is more important.

[velvet dagger]

I think age was being mentioned since like

He'll have multiple shots to improve

And with that in mind I'm generically happy with 1390. When I was applying some time back (out of 2400), the target was 2100. If you pass that you're at a point where the SAT is not responsible for your rejections

[sick burrow]

I mean it depends on the school though right?

Like isn't the mean SAT score at MIT like 1520

[velvet dagger]

I mean 2100+ is where it's like, not even the top school are likely to make a thing out of it. At least then

[sick burrow]

Also aren't a lot of school test optional now anyways

[velvet dagger]

Now my advice is a bit different since the test got easier and has only two sections

Let's say 700+ each section and at least 750 on one/1450 total?

[sick burrow]

Hm?

Isn't it two sections that are each worth 800

Out of 1600 max

[velvet dagger]

Yeah

I'm saying out of 1600 you probably want at least 1450

[vivid halo]

is getting a 1090 on an SAT good if you're only 9?

getting a 400 on the SAT when you're 1

[sick burrow]

Is getting a 1080 on the SAT good when you're a gpu??

[distant vortex]

Getting a 69 on the sat is good at any age

[sick burrow]

Or should I be taking the AMD exam instead

[crystal stream]

looks about right for a sat score curve

[odd narwhal]

400 is the minimum score right

[blazing pawn]

I dont think this is good advice anymore

at top universities at least

But in general its very good

[vivid halo]

yea that's the joke

[velvet dagger]

Yeah I mean like I said now I think 1450 is kinda the replacement minimum since the test got easier? Or maybe 1500?

Definitely 1500

[blazing pawn]

i mean you just want to be at

at least the median score for where you are applying

preferably higher

which tops out at like 1520ish most ivies and stuff and maxes out at like 1540 for caltech

[velvet dagger]

I mean do they weigh it that hard? I feel nobody cares about the difference between 1500 and 1600 lmfao

Like that's borderline statistical noise

[blazing pawn]

Uh it depends on the place

most dont really

[velvet dagger]

That's where you've sorta hit the bar you need to hit for SAT and now they focus on your actual shit like grades, ECs, essays

[last oxide]

youre borderline statistical noise

[blazing pawn]

But if there are a lot of people applying and you see two pretty similar app but one person has a 1500 and the other has a 1540 its going to have an impact

even if its minor

and u dont really want to be in the position of someone seeing ur score and going "well, thats a little bit below our average..."

[velvet dagger]

Would it really? I feel like with how much they care about holistic admissions I'd likely expect that except at Caltech

[blazing pawn]

it wouldnt make or break ur application though

[velvet dagger]

They just see is SAT > X?

If so coo we now forget what your SAT score is

Definitely GRE is pretty much like that

[blazing pawn]

I dont think theyre gonna forget considering ur app is reviewed for like 10 minutes lolz

[velvet dagger]

And back in the day 2100 was effectively that, maybe there's a bit of a difference between 2100 and 2200 lol

[blazing pawn]

or let me put it like this

if i was applying somewhere and i could retake for free

[velvet dagger]

But 2200 vs 2400 is no effect

[blazing pawn]

i would if i was below the median

i wouldnt if i was above it

But i would still apply either way

[zinc lily]

You got partial me

[blazing pawn]

also it kind of depends on how ur applying and where bc these stats get deflated a bit by people who have non academic "spikes" or whatever theyre good at and get in with like 1300s and such

[zinc lily]

Are they chess ratings?

[blazing pawn]

No lol

SAT scores

[zinc lily]

ok,
I was going to say 2200 and 2400 are entirely different 😄

Do ppl score full in SAT?

[blazing pawn]

occasionally

u can just google like

"SAT 1600"

[zinc lily]

Do we hear about them later?

[blazing pawn]

No idea what u mean by that

[leaden torrent]

perfect scoring the sat isnt particularly noteworthy

a decent chunk of top students do so every year

its certainly not "the norm" but it happens

[blazing pawn]

I think that once u reach just under the median they start becoming like

exponentially less valuable

at most hard to get into places

[zinc lily]

Which is the best college for math in US? And to get into it we give SAT right?

[leaden torrent]

a sat alone will not be enough for any top school in the us

theyre gonna look at your grades, your essays, your ecs, your background/demographics

anyway, there isnt a clear "best"

especially at the undergrad level

[blazing pawn]

The best school is wherever i end up

to be decided

[leaden torrent]

at the grad level the traditional "big 6" are princeton/stanford/mit/harvard/berkeley/chicago

but this is very rough

since advisor quality is way more important than school prestige

harvard, despite its prestige, has kind of been bleeding good advisors in most fields recently

i still wouldnt complain about going there but

it makes comparison hard

at the undergrad level, you have even more factors to consider

like program quality

do they let you skip courses to take more advanced material? do they have strong reus or other opportunities for undergrad research? etc

i'd rather an unrestricted program with plentiful research opportunities at a top 20 than a restrained program with hyper competitive research positions at a top 5

but thats just me

[blazing pawn]

Nami do u think that would be relevant to me at all as an undergrad

Probably not right

The advisor thing

[leaden torrent]

idk

im a bad judge of this

the point is that theres so many factors that its hard to make an informed decision imo

without direct, personal advice from someone very knowledgable about you and your goals, at least

[odd narwhal]

I was just making sure I got the joke

[zinc lily]

Money/family social status?

[leaden torrent]

not really, thats factored into scholarships though

but unless your parents are "donating" massive sums

thats not supposed to play a role in admissions

just aid

UCLA > Cal

Fight me

[leaden torrent]

FIGHT ME

I don't really care that much

I'm just salty that berkeley has now rejected me twice

Gonna make it thrice soon

Also socal is better than the bay area

[deep mango]

bay area >>>> socal

[dapper pivot]

is consciousness a bunch of chemicals ?

[deep mango]

yes

but they're all my chemicals

[dapper pivot]

it’s so interesting though how can we put a bunch of chemicals together and it works 😭

[eager crescent]

magic

[velvet dagger]

My impression is that socal is probably more pleasant but Bay area weather is better

Like Bay Area seems to have optimal weather

[crystal stone]

False

[velvet dagger]

Which part do you disagree with?

[crystal stone]

The beay area weather being better

bay*

Irvine has like perfect weather

And you can't beat it

[velvet dagger]

Socal summer seems unpleasant

In my mind Bay Area is like

Breezy and 50-70 for the vast majority of the year

[crystal stone]

Live closer to the beach -- the costal breeze cools you off a lot. There's also plenty of parks to go into that are really nice

[velvet dagger]

I guess in what way is it better? Like what's a time of year that you'd rather be in socal than norcal?

[crystal stone]

Every time of the year

The food in socal, particularly LA and OC are far superior to the food in bay area

Even down in SD the food is really good

[velvet dagger]

I buy the food being better in socal for sure

But I mean even if beach in summer is fine, I don't think it beats having 60s in the summer

[wild lantern]

I doubt food is really any better or worse in the bay area compared to socal.

Maybe socal has more good big name places?

[deep mango]

i heard this from a lot of socal people in berkeley

it smells like bullshit to me

[velvet dagger]

It seems quite plausible tbh, if only because Bay Area just doesn't seem like... Idk a place you especially associate with food. Socal not really either but it stands to reason that they have stand out good Hispanic food

[crystal stone]

Better Mexican food, better vietnamese food, better chinese food, better korean food, etc.

LA and OC are just OP when it comes to good food

There's a vietnamese place in OC that got a michelin star

So fuck you Bay Area

[latent forge]

how do people get permastudying?

is that a soft ban lol?

[neat lintel]

ask mod

[deep mango]

permastudying just removes you from general discussion channels

[latent forge]

tim onbrian

im pretty sure

also im kinda sad to lose ivory tower

[deep mango]

tim is a seethie still

you would still be able to see ivory with permastudying

that's the only off topic channel that isnt blocked

[latent forge]

i just need to become honorable trusted or adv helper or helper or very cool ppl or misc roles

johan just slightly off topic

but do you know anything about geometric realization

[deep mango]

johan just slightly off topic

but do you know anything

[latent forge]

ryc do you

in class today

[deep mango]

🐙

[latent forge]

we were talking about showing equivalence of categories for category of chain complexes and something else

some phd chad mentioned using geometric realization and I think he said its used to show something, but I wasnt able to follow so easily

[deep mango]

i have no idea

this seems like something someone here will write you a big blogpost about

[latent forge]

but I think first I need to understand homotopy category

[deep mango]

that nobody asked for

[latent forge]

meh

i hate life

why cant i become older like you and know lots of math

[deep mango]

well you're learning math i don't know now

[latent forge]

give me two years back from league of legends or highschool and id be happy

i want to learn the cool analysis you know but im straying further away

[deep mango]

i just wasted 5 hours watching survivor, then big brother, and then playing celeste and beating 1 level

so

[latent forge]

sounds comfy ngl

cooking and rock climbing and anime have been my cope

[deep mango]

not as much anymore

i'm bad at it

well i'm pretty good at celeste but i've played it for a long time so i should be

dabbed! loL!

[latent forge]

i dont know if this is a thing but you ever feel anxious for no reason because you can’t remember a definition. yesterday I was just filling up my water bottle thinking about definition for submersions immersion imbedding and constant rank. but i forgot them and was thinking of how to rebuild the definitions but then i realized I dont remember if submersion was one with constant rank dimension of M or N given a smooth map from M to N.

[deep mango]

i am bound in the suffocating gauze of your relentless torment...

[latent forge]

is there a anxiety called definition anxiety

tbh its in top 10 most stressful feeling ive had recurring

[deep mango]

i feel like this happens to me often

[latent forge]

next to getting harrased by others for no reason

[deep mango]

but i've gotten good at just ignoring it and going to look in a book to remind myself later

[forest jackal]

it shouldn't stress you out as much as it sounds like it does

[latent forge]

i need a cure or prescription or something

it has me sweating tbh

[forest jackal]

lol

[latent forge]

like i notice my back and armpits sweat

hands get clamy

[velvet dagger]

I don't know if definition anxiety is a thing in itself

It's prob one of those things where

You'd get anxious whenever you feel like you're lacking in something important

And it just so happens to be the case that you put importance on definitions, so when you forget you're like fuck I should know this

But I would be truly surprised if it's like

You find being able to do X as a more important endeavor than knowing definitions

Yet X doesn't make you anxious while definitions do

[latent forge]

yea but i think its a bit unhealthy for me. on sunday I got stuck in woods with my friend, 5 km deep on truck road and car broke down. I was more stressed about not finishing homework or remembering the problem correctly than getting back home. So maybe it is a combination of things.

Also its not just definitions you are right, but sometimes its just theorems and not remembering correctly

every weekend im just hoping ill catch up on learning but the cycle just repeats

[velvet dagger]

I mean it's probably general anxiety. If this anxiety were strictly tied to math, and other similarly stressful endeavors didn't do this to you

[latent forge]

if i get caught up for diff top the problem becomes algebra, if its algebra problem becomes algebraic topology and it keeps going

[forest jackal]

My memory is terrible compared to what I would like it to be, but its fine. That gives you lots of little exercises to piece things together in your mind.

[latent forge]

the only time ive felt more anxious is when I ran track in highschool

[forest jackal]

and being distracted by math when doing non-mathematical things is a rite of passage for mathematicians, it's almost impossible not to be.

[latent forge]

typical anxious activites like public speaking dont get me

[forest jackal]

if its anxiety and no good feelings though, that's a different matter.

[latent forge]

i feel relieved when I check and remember definitions correctly

Also another sligtly off topic but I think I need to follow ryc path and learn more applied and physics stuff

[eager crescent]

Try forcefully thinking about something else when that happens?

Idk if it would work

Surprised too

[latent forge]

Talked to someone today about operators on wave functions and I dont know what either are precisely. I was told that operators when applied to wave functions give you a probability density of physical observables or something or the other?
Also wave functions generally have information on the system being worked in? Im not exactly sure what operators are supposed to be so I kept thinking of operators like in math.

All in all I am shit at understanding physics language and need to branch out to some other applied field

[eager crescent]

physics is cool

I wish I had kept studying physics in parallel to maths

[latent forge]

Is there a topic like physics besides computer science that uses loads of math and is useful irl. I had an awakening that math felt truly useless without society or being applied to something. I always felt like it was a super tool that would help me solve a ton of problems but when confronted with outside problems im at a loss.

[eager crescent]

engineering

robotics

[latent forge]

same ish

[eager crescent]

social science

[latent forge]

engineering is always cool though

[eager crescent]

archeology

[latent forge]

but when i meant loads of math i meant outside of pdes

[deep mango]

What is that supposed to mean...

I don't know a lot of physics but I undeniably know a little

[eager crescent]

information theory, it's not cs or physics but more of a mix

[latent forge]

I was thinking of heading down a statistics rabithole

[eager crescent]

Oh statistics too yes

[latent forge]

because I honestly find lots of methods interesting

[deep mango]

What is a statistics rabbithole

[eager crescent]

Why didn't I think of that, I study stats

[deep mango]

it goes like 2 feet down

[latent forge]

learning stats so much that i feel removed from math

[deep mango]

teafortwo lurkie....!

[eager crescent]

Stats is maths

[latent forge]

lurkieturkey

nlab is way cooler than I thought

[atomic cypress]

Pick up Laszlo et al, Gine and Nickl, and Keener to do mathematically challenging stats.

Nothing else is that compelling mathematically.

[latent forge]

ok

[eager crescent]

Statistical thinking can be somewhat philosophical

[latent forge]

my largest problem is finding time and commitment ive noticed

[eager crescent]

At least I see some statisticians try themselves at philosophy

[latent forge]

Is there a khan academy for analysis?

[atomic cypress]

Laszlo does convergence of learning methods, has a stochastic dynamical systtems feel. Gine and Nickl do "how do I estimate things I can't discretely parametrize". Keener does statistical foundations and theoretically you can read just Keener and know more stats than most MS students in stats.

[eager crescent]

how is it compared to Lehman

[velvet dagger]

I see Laszlo and immediately think Babai and I'm like :0

[latent forge]

why ppl shit on stats so much

[atomic cypress]

literally who is lehman

[velvet dagger]

Idk how much shitting on stats I see

People def don't like it much

Because it can be painful

That's actually really good

[atomic cypress]

stats taught right is reverse probability theory. instead of knowing the distribution and figuring out its action, you know the action and figure out the distribution.

[eager crescent]

Because they did stats in hs

[atomic cypress]

anyways feel free to shit on statisticians, they dont know measure theory

Gator talk to your average stats phd

[eager crescent]

Tbh it's true

As much as I hate it

French statisticians know measure theory though

[atomic cypress]

yes, but the frenchies do stats like math people do prob

pascal didnt know anything

he just randomly wrote down things until he was correct

its how i write papers

game recognize game

[eager crescent]

UK statisticians probably as well

[latent forge]

wdym

they dont?

do physicists?

[atomic cypress]

no lol

physicists write measures but cant tell if what they wrote makes sense

believe me, im working on formalizing measure garbage physicists thought worked but actually runs off to infinity

[latent forge]

i wouod be interested to hear but probably over my head

i need to level up my analysis so much

i think ill take grad analysis senior year

[eager crescent]

Erich Leo Lehman

[latent forge]

also where do you give talks irl

[atomic cypress]

theoretical statisticians and physicists actually do math seriously

[latent forge]

i wanna practice giving more math talks and getting grilled by math audisnces

[atomic cypress]

your uni should have seminars

[latent forge]

yea but they are classes

so ur telling me i gotta sign up for seminar classes

bruh moment

[atomic cypress]

oh hey i have a lehmann book i "found" but never read

never saw the point but maybe itll change

keener is high stats theory, he's good shit

[latent forge]

weener

[atomic cypress]

i should probably also rec van der Vaart, he's also stat theeory

[eager crescent]

What are the books names

[latent forge]

also wtf

[eager crescent]

Especially laszlo

[latent forge]

i looked in analysis pinned

[eager crescent]

Can't find the name

[latent forge]

where tf gomez get all the time to review those books

[atomic cypress]

laszlo called nonparametric regression, gine and nickl is infinite dimensional, keener called theoretical stasts, van der vaart called asymptotic stats

i have more recs but theyr specific to my interests, you should also pick up a book on monte carlo methods, there are some oddly nontrivial things there

[eager crescent]

Lehman's (and Casella's) theory of point estimation is a classic for point estimation, often recommended

[velvet dagger]

You sure it's that one? I don't see anything notable in the analysis pins

[latent forge]

nvm it was sloth

[velvet dagger]

Oh lol

[eager crescent]

Tbh I have never read it, only seen excerpts

[latent forge]

in bookrec

[atomic cypress]

imagine estimating points

i just draw them at random

[velvet dagger]

That was because for those subjects I was literally looking for good books

[eager crescent]

Monte Carlo is a vast topic

Can be very fun as well

[atomic cypress]

yes, i love running monte carlos, so much fun

[latent forge]

Lso you said aluffi has bad exercises

[eager crescent]

Mathematically fun

[velvet dagger]

Like I start with D&F, nah boring. Artin, nah it mixes the group theory with the linear algebra and I'm trying to speedrun group theory. Herstein is good for GT but later not anymore so I need something new

[latent forge]

which ill agree some of them are lazily worded

[atomic cypress]

just learn algebra off wiki

[velvet dagger]

I help a friend through Aluffi problems, they make me wanna pull my hair out

[latent forge]

actually though

[velvet dagger]

I read Jacobson and it's just nice

Etc

[eager crescent]

Can a mod pin that

[latent forge]

like which problem wad the worst?

im on part e of the book

[atomic cypress]

read aluffi and do dummit and foote problems

[velvet dagger]

Ider but like

[latent forge]

part 3*

[velvet dagger]

I feel Aluffi just kinda has a bunch of problems which are just

[atomic cypress]

i say that but i havent done anything but skim aluffi 😂

[latent forge]

aluffi is shit at defining things ill say that

[velvet dagger]

Yeah this proof is easy but it's long and I don't wanna write it

[latent forge]

i had to use wikipedia to find what univeral property is more formally

[velvet dagger]

So I'll just give it to you even though it's not that interesting and probably not very informative

[atomic cypress]

aluffi is hilarious

you shut ur dirty mouth

[velvet dagger]

Maybe you can make a case that it's largely repeating a textbook proof to solidify or whatever

But it feels lazy

[latent forge]

it is lazy

the chapters are lazy I can verify

[atomic cypress]

dummit and foote had a bunch of "write the jordan form" problems

holy moly

[latent forge]

some intution is built but at other times im wondering how can I use this category theoretic concept I just learned to to make this problem easier

when its shouldnt really be done

Also I have a smol question

[velvet dagger]

Yeah jnf problems are painful

[latent forge]

We have that for category of modules direct sum is the product and coproduct

But if we take an infinite product this changes

We have that infinite product stays the same but infinite coproduct has these weird conditions

[gloomy breach]

homies

where do i publish math papers

i got trolled twice now

so please not again

[atomic cypress]

vixra

[latent forge]

I think I might have to just go and work out a bunch of examples

[atomic cypress]

if you have a real paper reach out to a prof

[deep mango]

is this dude's name even pingable?

[gloomy breach]

thing is i dont have a prof

yet i have a real paper

[deep mango]

do you though?

[gentle bay]

Lol exactly.

Maybe he is not doing a PhD.

Doing Masters or Bachelor's or HS or something and wants to publish.

[atomic cypress]

if you have a real paper reach out to a prof and theyll know

[deep mango]

collatz or riemann?

[latent forge]

senku isnt perma studying?

[gentle bay]

perma?

[latent forge]

oh thst is tim

[gentle bay]

What?

[atomic cypress]

tfw they never claim to solve the bsd

[latent forge]

i thought you were tim o brian

[gentle bay]

Oh okay.

[neat lintel]

remember paying california's rent price is harder than publishing paper

[latent forge]

bsd a deez nuts joke?

[gloomy breach]

okay homies

thanks

see you in the textbooks

[latent forge]

😓

[gentle bay]

Ah yeah that's the spirit.

[eager crescent]

reach out to a prof if you want to be published, they'll know which journal is relevant

And also if it's worth the journal's time

[gentle bay]

Leave it.

[velvet dagger]

Senku has a different energy than Tim but their avatars gave vaguely similar vibes

[neat lintel]

if there are some mistakes, they will let you know that you'll have to revise

[gentle bay]

Oh do they.

Mine is a Tardigrade.

The strongest.

The most surviving.

And his/her/their is a cat.

The supremacy.

Mine is stronger and chiller thought .

[gloomy breach]

Cats>Dogs

[gentle bay]

Yessssss.

[neat lintel]

yes

[latent forge]

oh rip

i want to do research soon

idk who I even ask and idk the topic tbh

presumably the topic would be on one of the classes im taking but all the classes feel like I need more prereqs before I begin research

[gentle bay]

You are doing PhD?

[latent forge]

no bachelors

but it seems like getting math research is one of those hard to do things

I should only ask profs once im well adjusted anywayd

[gentle bay]

Oh cool.

Which year?

[latent forge]

im year three

covid wasted my potential methinks

[eager crescent]

I didn't even need covid to waste my potential

More seriously though try to ask profs to do a research internship with them

Research is usually done after a masters though

Well in the usa you can enter a phd right after undergrad but I think it includes masters?

[gentle bay]

Oh cool.

[atomic cypress]

In theory it should be possible to get a PhD without an MS in the US, but the requirements often overlap

So it's often as simple as just applying for the MS.

[pale orchid]

how does that work? you write a thesis about 2~3 years into the program?

[devout nacelle]

So you effectively spend the same time as an MS just taking classes/giving quals?

[pale orchid]

but you have to pass the quals for a masters as well? i know you do to go on with the more research side of a phd

[devout nacelle]

Hmmm, makes sense

[pale orchid]

so the question was more like for those ~6 year programs where you go in as a bsc and directly go for a phd

what do you do in the middle to also get a master's degree, if you want one?

i see

that's pretty handy

right, i see it mainly as a fallback measure

pretty reasonable, too. i can imagine a lot of people jumping straight into phd from bachelor might find out they're not that into academia

lol yeah

[atomic cypress]

A PhD can be a path to a free Masters.

No question about funding.

Of course that's a good way to burn bridges

[pale orchid]

yeah, especially if the funding came from a project

[eager crescent]

Europe master race

[pale orchid]

wait, i've seen this one before

not really true

isn't education super expensive in netherlands? also uk and switzerland, but i suppose those don't count

i guess i was looking at it from a foreigner's perspective

epfl is as expensive as netherlands for foreigners

ofc being born in a 1st world country is life on ez mode

i'm already there 😛 did msc and doing phd there

i was just commenting on the truth of "free education"

the bad kind cuz i'm an eng

bad multilinear algebra, statistics, and optimization in a trench coat

commonly known as signal processing

wdym by filter theory

like inverse problems and stuff?

LSI systems and junk

yeah

it includes what i mentioned, but goes more in depth

i do a lot of the basic form of that

yeah, electrical engineers run the kid version of this in bsc

some of it includes this, yeah

stuff like "beamforming" is optimal filtering based on the observed data's probability distribution

telecom is more like it

like you have antenna arrays and feed them specific signal patterns so that the radiated fields have a specific shape

this is the same as applying filters in spatial domain

thüringen 🥲

you in thüringen too?

sachsen

afd ftw

go blue

2 years ago, ye

no, so far i have only assisted in a handful of compressed sensing lectures

but i do supervise a bunch of students doing masters

they have some small research projects, like the so-genannte hauptseminars

gutachten as well

i'm hired at the uni as wissenschaftlicher mitarbeiter, so

if the prof wills it, it happens

[surreal sapphire]

i think you need the degree you are grading

so if they are doing a masters and you have a masters, all good

i know there were some issues when i was grading exams for bachelor classes and didnt have a degree yet

no

[pale orchid]

i also don't usually do it "alone". there's a chief researcher above me who has a phd, but usually i handle it myself

[surreal sapphire]

habilitation is distinct from a phd

(and kinda going out of fashion)

[atomic cypress]

oh do you also do spdes

what area

oh grats

[pale orchid]

nice

[atomic cypress]

well spdes is a meme, have fun

best area of math

[pale orchid]

i see spdes in related stuff, like people simulating acoustic fields for seismology and ultrasound

i don't do it myself tho

[atomic cypress]

I'm in the US, I do the intersection of SPDEs, analytic geometry, and physics

It's not that bad, I just learn less of each thing

[surreal sapphire]

i start my master thesis soon(tm)

then probably phd in crypto

ye

[atomic cypress]

yeah crypto big

what particular subarea

just general?

[surreal sapphire]

i do nt and graph theory most

[pale orchid]

Lochverstärker verstärkt Löcher

[atomic cypress]

nt?

[surreal sapphire]

and the idea is isogeny based cryptography

[devout nacelle]

Zahlen theorie

[surreal sapphire]

which is kinda both

nt = number theory

[atomic cypress]

neato

[surreal sapphire]

also this

[atomic cypress]

yeah i know what nt is, i just meant that as a followup

[surreal sapphire]

oh ok

[atomic cypress]

i coauthored one paper on lwe lattice crypto

it was very cool, but i decided not to pursue crypto

[surreal sapphire]

my bachelor/master thesis advisor knows some guy and they know the top researcher in post quantum crypto

[atomic cypress]

name?

[surreal sapphire]

luca de feo

and they already paired up a math and a cs grad to research that

so the idea is that i do the same

[atomic cypress]

ahha, I found de Feo https://sike.org/

3rd round NIST postquantum submission

[surreal sapphire]

yeah

this is the latest stuff

[icy forge]

That acronym

[surreal sapphire]

its a spin on elliptic curve crypto based on random walks in isogeny graphs

[icy forge]

are the people involved zoomers

[pale orchid]

@lilac raven this is the sort of stuff i more often deal with, related to your filtering stuff https://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=1197303

[surreal sapphire]

not quite

[pale orchid]

that and subspace techniques to separate signal components from noise

prolly

how about here

http://www.sal.ufl.edu/eel6537/2006/rcb2.pdf

petre stoica shows up a lot in this type of stuff

you can kinda ignore it

it mostly defines the structure of what ultimately boils down to y \approx Ax + n, with different statistics for n and a different structure for A depending on the application lol

and different properties for the expected value of (Ax + n)(Ax + n)^T

[atomic cypress]

Van der Vaart had this very cool terminating chapter on semiparametric statistics with the parameter on a manifold.

I'm loosely speaking looking at flow and transport equations that have singular geometric interactions that are useful in physics, which break symmetries that we can tackle by stochastically renormalizing things. There's also some SUSY on the horizon which is making me but I'll pretend I'm not doing any of that yet.

whats with the sus eyes

oh

as ive been discovering, neither do i

basically think of it this way

navier stokes on bounded domain

water hit wall

no more differentiable

turbulence what happen????

yes, im basically staring at the problem like a dispersive pde

looking at the transport of 2-forms that have symmetry up until collision with the wall

at which point it's time to start doing big brain things like uhh checks notes stochastic ricci flow?

a meme

math thing, for 3d flow you defind as the calculus curl of velocity field

you can treat it as a differential 2-form

well that's vorticity but anyways

i have no idea

[inner finch]

capon beamforming

[atomic cypress]

who knows what people do in continuum mechanics

everyone has a different idea of whats interesting or useful

whoa that cool

what the fuck

physics departments would get wrecked by this class

is this math

why would math people teach continuum mechanics lmao

[pale orchid]

they probably do it with discrete approximations

then it fits well

efficient algorithms, memory-aware computing, matrix-free methods, etc

robust opt

turns out the way you write the stuff on paper is often not at all how you actually do it cuz you wouldn't have enough resources

[latent forge]

oh

i recently learned that vector fields are related to sections for vector bundles

makes sense

i think i understand the basic idea of constructing a fiber bundle now too

but it seems applied to almost everything in a way i cant describe well

applied to a lot of things I should say

[thorn brook]

bundles

me:🚶‍♂️

[deep mango]

[cinder zephyr]

Fiber bundles

ECE majors crying over the fact that's not what they think it is

[neat lintel]

[blazing pawn]

Bundles are poggies

[vivid halo]

elementary formalization

[latent forge]

ece?

engineering civil engineering

wait

kernel is a fiber?

at 0

[cinder zephyr]

Electrical and Computer Engineering

Uh

Idk

[latent forge]

i think so

because you have a map from A to B

kernel is when map on A is 0 in B

fiber at 0 in B is subset of objects in A mapped to 0 in B

sounds foolproofed

oh

i now know what a fiber bundle is

So a vector bundle of a linear transformation f X to Y is {f-^-1(y)}_y in Y such that f^-1(y) isomorphic to some subspace of Y?

[fast ivy]

Yeah, the fiber of a function $f : X \rightarrow Y$ at a point $y \in Y$ is simply defined as $f^{-1}(y)$. This is a very general definition.

[fathom swallow]

MisterSystem

[fast ivy]

Not really

Mainly because if f : X -> Y is a linear map between two vector spaces, in general f^-1(y) is not a subspace of X.

We can guarantee that for y=0 tho

Prolly the nicest way to get a vector bundle that is induced by a linear map T : X -> Y may be like taking ker(T) or Im(T), but these are trivial vector bundles. I suppose you were trying to define something more interesting.

[latent forge]

uh

nah

i think I just need each fiber to map isomorphic ally tonsome subspace of of Y

or nvm

i just read nlab definition and was remembering covering space definition for manifolds where each fiber is locally diffeomorphic to something

[fast ivy]

Yeah, but that doesn't make much sense since f^-1(y) in general is not itself a subspace of X.

So it doesn't make sense to ask for an isomorphism

we need #chill but for text and any memes must be related to discussion

seriously

conversation on anything rarely lasts more than a few lines on #chill

in 9th grade we learned trig but like only with triangles and not the unit circle definition, in 10th we learned abt the unit circle.

imo trig would go way better if instead you only taught it in 10th grade, after complex numbers, and also teach the unit circle definition
