Idk about germany, but water and bread are free in France when you go to resto

normally the free water is tap tho

Don't take advantage of it tho

why would you ever drink tap water?

and tap water from a random source at that?

What is quality water?

@woven whale weather is definitely not a benefit of the us

it is just the most clear tap water in the country

ummm what?

??

#

how is water being clear something that makes it good

#

that should just be, the standard

yeah sure should be but you know how it is

Has anyone tried Wolfram Alpha Pro? It's a math AI engine. One of its features is helping to break down some problems with a step-by-step solution. I wanna know how it is from a person who has tried it

#

I've read a couple of reviews but there's varying opinions on it

woven whale
#

I have it on my phone

#

because there it's a one time purchase of like 2.99

delicate tide
#

Is the mobile version better than the website version on laptop?

#

Aside from the price

#

Or wait

#

You're saying it's a one-time purchase for accessing all the features, including Pro features?

#

Like showing step-by-step solutions

#

In that case that's better

#

Because on laptop you have to pay monthly

Is it also able to graph 3 dimensional planes?

Thank you once again

@woven whale It's not able to answer continuity questions

#

At what point (x,y) in the plane are the functions f(x,y) = sin(x+y+1) & f(x,y) = ln(x²+y²-4) continuous?

#

I tried getting it to answer it separately

#

How do i need to frame the question

#

Probably

#

Thing is, top schools have demand and capability to offer higher level classes than many other places

upbeat shore
#

The biggest difference will be the quality of the professors you'd be exposed to, the quality of the advanced classes, and peer effects. I don't think the work is substantially harder except in a couple of weed-out courses like math 55 at harvard or honors analysis at uchicago

#

There is, for instance, a lot of grade inflation at princeton.

velvet dagger
#

For instance, the math major at many universities will have a progression of calc 1/2/3, linear algebra, differential equations, discrete math/intro to proofs as the first 2-3 years

#

How many classes will there be beyond those?

#

Hopefully some subset of real analysis, complex analysis, point-set topology, abstract algebra, partial differential equations, probability, numerical

#

Perhaps depending on whether the school leans pure vs applied math

#

Maybe some of these are gonna be considered graduate level

#

I've heard there are schools were Baby Rudin is considered a master's level course

#

Oh I wasn't talking about that as a sticking point so much as saying like

#

Maybe among schools literally ranked 200, you might find one school is mostly applied math

#

So they are more likely to offer shit like numerical analysis compared to point-set topology

#

But, say at Chicago

#

The Rudin-level course is typically done in second year

#

But now you have undergrad electives such as stochastic processes, representation theory, functional analysis, etc that are offered consistently

#

And grad courses start much higher

#

Anyway that was my general spiel to give a self-contained answer to your first question. Lower ranked schools, esp in lower priority majors like math, may not have the demand or resources to offer many advanced classes, so there is a risk that you'll be restrained somewhat. At least one student in this server I know is struggling with that

#

As for quant, are you looking to do quant trading or quant research?

#

"not going for a phd" okay so you're more quant trading then

#

Quant jobs are competitive and the name of your school can help

#

I mean if you're asking, presumably you have an offer at one of these top schools?

#

If so is there any reason for you not to go for it?

torn willow
#

Well sometimes you need to be in a certain school to get in

#

Otherwise they won't even look at your resume(for like Jane Street)

velvet dagger
#

Like if you don't have a choice you don't have a choice, at that point you make do with what you've got

#

But unless finances are gonna fuck you up at a top school, which is if anything less likely since aid is pretty good

#

I don't see the reason why not to go with the best place you can get into

#

Yes but master is tricky because it can be very expensive, and not as easy to get financial aid for as undergrad

#

I mean what's stopping you from applying to those sorts of places right now?

#

If you're applying to the states, financial aid can even cover that

#

In my undergrad, my total cost averaged 8k/year (because they determined we could afford that)

chilly hull
#

dami could i do lees diff geo after schroder/artin/bredon

velvet dagger
#

This included dorm, meal plan, and health insurance

chilly hull
#

alongside folland

velvet dagger
#

Undergrad = bachelor's degree

#

So my 4 year bachelor's degree costed me on average 8000 USD/year for living expenses. Full cost of living expenses is more like 15000-20000USD/year, but my financial aid covered a part of it too

#

I'd say apply to the places which give aid just to see. If it's too expensive you don't go

#

But don't deny yourself opportunities before it's necessary

wooden flax
#

You don't even need to be top 200 for a decent undergrad program, a college near me is literally unknown/unranked yet officers some courses in eg basic representation theory/algebraic geometry

velvet dagger
#

Invictus to be fair I think that's a matter of luck

wooden flax
#

obviously theres some correlation/causation

#

but there are t200 programs that probably do not have a decent program and non t-200 that do

velvet dagger
#

This is #72 according to US News

wooden flax
#

yeah this seems to be mostly applied

velvet dagger
#

The other thing is, there's no grad program

#

But yeah I'll say it depends on whether you mean top n overall vs in math

wooden flax
velvet dagger
#

I'm saying in pure

wooden flax
#

oh ok

velvet dagger
#

Like, you have these options for pure and it's not like oh I'll just do grad topology....

wooden flax
#

that dosent mean anything, right

#

georgetown is 22 overall

velvet dagger
#

Yeah the correlation is definitely on the loose end to a degree

#

Though I figured there aren't gonna be many places that are, say, top 50 in math but not top 100 in the country. I'm not really familiar with many such schools so don't hold me to that

#

But it does feel like a school's overall quality/reputation is gonna be correlated with its likelihood of having stronger students, and thus a demand for more advanced coursework, as well as the resources to meet that demand

#

Especially in math, since that's gonna be a bit lower priority

@molten ibex just to set the record straight i did not disappear due to admitting my own "defeat" or whatever

#

we simply have different desired levels of formality when it comes to epsilonics

#

and mine is lower than yours

#

partly because i personally dont like to spend energy on formality for formality's sake

molten ibex
reef carbon
#

eh

#

how much does it matter

#

are you gonna file for getting me stripped of my math license

molten ibex
#

it does not

exactly

formality matters only insofar as it helps clarify, imo

molten ibex

but i wonder why you can not admit mistake though

i don't think it is a mistake

it is more like an inaccuracy

By some careful inspection, a pattern may be found.

velvet dagger
#

I mean the pattern I notice right away is

#

First row of first matrix is abb
Second row of second matrix adds one letter to that, so applying a->b->c->a
First row of third does that again

#

Similarly, cac->aba->bcb is taking the sequence cac and just applying c->a->b->c

#

So the last one would be the first but with first and second rows swapped

but not very seriously

at some point i want to read the green book and dip my toe into complex cobordism things

like the contents of a first course in alg nt and thats it

its neat but i have no particular interest in pursuing it long term

do want to learn more though

like basics of rings of integers, intro class group minkowski things, and basics about ramification and inertia/decomposition groups

you need to construct a homotopy from f0 to f1

what do you know f0 is homotopic to

whats 8-12b asking

the set of discontinuities of a function of bounded variation is countable (empty, finite, or countably infinite)

is this a dini moment? 🤔

storm sage
# blazing pawn what do you know f0 is homotopic to

ah okay so since f0 g0 is homotopic to f1 g1, we konw that f0 g0 g1^-1 f1^-1 is nullhomotopic, so f0 is homotopic to f1 g1 g0^-1 but then we know that g1 g0^-1 is nullhomotopic, so f0 is homotopic to f1

In mathematical analysis, a function of bounded variation, also known as BV function, is a real-valued function whose total variation is bounded (finite): the graph of a function having this property is well behaved in a precise sense.

what's the galois correspondence

#

something about covers

#

covers and subgroups of the fundamental group?

storm sage

If you have a path connected locally path connected semilocally simply connected space, then there's a one-to-one correspondence between the subgroups of the fundamental group and the covering spaces (up to isomorphism)

there's like an isomorphism of the lattices

storm sage
#

it's like, really neat, but I don't know why I should care about field theory 😭

neat lintel
#

the hypotheses are kinda silly though

#

path connected locally path connected semilocally simply connected space

storm sage
#

I understand where they're all used tho so I'm happy

#

and any space I care about is probably gonna be that

neat lintel
#

lol

#

some field theory popped up in my algebraic geometry course a long time ago and i just black boxed it

#

it made no sense to me but i also didn't need to know it deeply

storm sage
#

I guess I'll think about it more when I take algebraic geometry

#

if I take algebraic geometry

neat lintel
#

i think it's neat

storm sage
#

What's neat about it?

neat lintel
#

geometric arguments

#

i will say

#

my course stayed well within zero sets of polynomials opencry

#

nothing crazy abstract

#

it was cool to see how a lot of the stuff i knew only algebraically translated so well to pictures

#

there were a lot of results that were scarily close to things i learned in complex analysis

storm sage
#

👀

neat lintel
#

you know the identity theorem for holomorphic maps?

storm sage
#

yeah

neat lintel
#

two holomorphic functions which agree at enough points agree everywhere

#

there's a very very similar statement for regular functions on affine varieties

storm sage
#

👀

neat lintel
#

i don't remember the hypotheses for that one lol

#

trust me on it

lavish hull
#

Um

#

If the set of zeros of regular functions on affine varieities have accumulation points then

#

the regular function is zero

#

The complex analysis proof uses two things iirc

neat lintel
#

oh, yeah, another one. every holomorphic function on punctured C^2 can be extended to all of C^2. the same thing is true for regular functions and A^2 instead

#

removable singularity theorem

lavish hull
#

tt

#

does identity theorem for alg geom involve any extra theorems

neat lintel
#

idk

storm sage
#

ooooh

#

that's so cool

#

Makes sense since homolomorphic functions are just polynomials

lavish hull
lavish hull
#

There is a cool theorem saying that entire functions are all of form e^g(z) where g(z) is polynomial

but i misquoted theorem

Oh sorry do you dislike pings

vivid halo
#

what kind of stuff were you covering by the end?

neat lintel
#

sheaves, the abstract definition of a variety, kinda stuff

#

whatever you get when you patch together affines

velvet dagger
#

Wait so what'd you do before that? Just affine stuff?

neat lintel
#

pretty much

#

a good chunk of the course was on commutative algebra too

#

let me find my old notes

velvet dagger
#

This was a first course, right?

neat lintel
#

yes

vivid halo
#

ahh okay yeah so you were just building up the machinery to actually do stuff

velvet dagger
#

Yeah AG is one of those subjects you prob want more time with

#

Because there's a long setup phase and there's a lot of payout

vivid halo
#

I mean part of the issue is that if you spend time in class actually trying to develop the machinery instead of going too fast, then you don't have any time to like, do any actual geometry

neat lintel
#

it doesn't help that people kept asking the prof to slow down

vivid halo
#

yea

they should just say "skill issue" and speed up

I hate when that happens

#

table of contents from notes long ago

#

an absolutely fucking inordinate amount of time spent on sheaves

#

each section is one lecture, either one or two hours long

vivid halo
#

lmfao

#

yeah I mean this is all important stuff, it's just like

#

snooze

#

honestly every AG course should require registering for two separate sections

#

where one lecture series is this bullshit

#

and the other lecture series is like

#

actually fun

neat lintel
#

toronto would NEVER implement such a thing

i considered taking the graduate algebraic geometry course instead of this

i am talented

there are some people in my life pressuring me to go to grad school

velvet dagger

Gives you some wiggle room to decide, whether you want grad school or industry, and if you'll do industry, how you wanna make that move/posture

Eg are you more interested in ML, software engineering, quantum computing, crypto, blah blah blah

maybe if i sit down to read it

what the hell is ant supposed to accomplish

like cutting through the abstraction hmmCat what does this approach tell u about numbers that other approaches dont

A very dumb and not related example is how Galois theory tells you that x^5 - x -1 has roots that cannot be expressed by radicals, although there's no way to read that info purely from the coefficients. Algebraic objects have more symmetries and thus behave in a more constrainted way

reef elm
#

ahh i see

neat lintel
#

hello @hollow quest

hollow quest
#

Grüß dich

neat lintel
#

i actually got kinda

#

stumped

#

for some reason

#

because i didnt know how to account for the extra angle

#

that is phi

hollow quest
#

I see

#

Well

#

What you wanna do is resolve the velocity and acceleration vectors into components along and perpendicular to the incline

#

Then it's just a case of applying the equations of motions

#

Can we have that diagram here again

neat lintel
mental stratus
#

for inclined plane problems energy conservation makes life easier most of the times

hollow quest
#

Wait what are you meant to find again

neat lintel
#

the time it hits

hollow quest
#

ah

#

I don't think energy conservation would help us there would it

#

Anyways

#

Grab your incline

#

And rotate it

#

Until it's a flat surface

neat lintel
#

yeah

#

i knew it was like probably

#

just

#

making the incline be the x axis basically

hollow quest
#

A shift in perspective sotrue

neat lintel
#

OH WAIT

hollow quest
#

That's the best way to go about these if you're new to them

neat lintel
#

so do you just

#

subtract theta and phi

#

and boom?

hollow quest
#

There is also retardation in the x direction this time

neat lintel
#

but wait, you have to still account for the gravity change

hollow quest
#

Yes

#

Can you tell me the component of gravity acting along the incline

#

In terms of phi

neat lintel
#

hmmm that would be

#

gsin(phi)?

hollow quest
#

good

#

And perpendicular to the incline?

neat lintel
#

gcos(phi)

hollow quest
#

alright

neat lintel
#

Hmmm so I guess now it's easy

hollow quest
#

yes

#

Just equations of motions now

neat lintel
#

Is there anything else we have to take into account

neat lintel
hollow quest
#

not really

#

Unless they do something fun

#

Like explode the projectile

#

And break it into two pieces

neat lintel
#

Darn that was an easy question, should've made the rotation thing

hollow quest
#

And find the final positions

#

lmao

neat lintel
#

It was

#

Fucking wild

#

It was more about conservation of energy and stuff though

hollow quest
#

And the center of mass doesn't change

#

*relative position

i personally find they totally don't work for me, but what do you guys think

reading pdfs for long makes me dizzy

at least I have access to cheap Indian edition books

do u have any mileage with printing out notes and using them and stuff

neat lintel
#

you can buy second hand books really cheap

#

I bought around 8 college books in the last 2 years, total maybe 200 euro

neat lintel
#

Same, buy used books

#

Saves you a lot of money

#

You could always use some pirated copy or something on the internet, but I prefer physical books

#

Not that I have much money, but I can at least sell those books again if anyone is interested in them.

young quartz

there are some websites which print and bind books

all you need to do is upload the pdf to their website and pay

after that they will mail the book to your address

which is unlikely

though @tacit tulip if you dont even want to share your proof, this is the wrong place

so this is more a general discussion rule

if you make an outrageous claim without backing it up, thats not a good basis for discussion

if someone genuinely believes they proved [big thing] and posts their proof, discussing that is fine imo

just posting an outrageous claim is (close to) trolling
