#

Which project are you wanting to work on

vivid halo
#

Probably Jacob's?

bronze pelican
#

Me too

vivid halo
#

anything related to Shimura varieties

#

otherwise I do not care about this year's topic

#

I want to work on Project 1.2 Obtaining/effectivizing explicit exponents for Galois lower bounds.

Just curious, which math class do you believe helps you progress the most as a math student? I guess I mean like which class really helps you take the "next step" in terms of thinking, problem-solving, etc.? I really only took linear algebra and calc 1/2 but still don't feel like a math major per se. Just someone who took a little bit harder classes

solid snow
#

Probably whichever one is more proof based and abstract

#

Could be analysis, abstract algebra, 'abstract' linear algebra, etc.

haughty lintel
#

I see. Do you think any of those classes are self-study able given the few amount of prereqs i have? Im taking calc 3 next sem but other than that i dont think ill take any of those after ODE 1/2. (Which would be like junior year :/)

solid snow
#

you can self study mostly anything

#

it's just a question of how much effort/time you dedicate to it

#

a teacher and class certainly help a lot but catshrug

haughty lintel
#

fair enough. I guess ill just learn whatever i missed along the way. Ty!

dapper flint
#

i'd recommended going over some topics covered in calc 3, e.g. matrix algebra, vector calculus

#

before your semester starts

#

vector calculus, which is the last topic for my class, is definitely brutal since my prof just crammed everything in the last week...

How common is it for math professors go earn six figures?

check the UC pay figures and get stats

I want a holistic view, without doing the research myself

Oh lmao

bright hill
#

My marks have been good so far actually

#

And my classmate's have been terrible

#

Which makes me hate my uni so much more

fringe needle
#

I mean keep in mind you were doing math in your own time for a decent chunk of time before you started uni

#

Which isn’t the case of most people

neat lintel
#

I’m a good student

#

This year I don’t have any failed subject and they’re all over 60%

neat frost
#

You're also a mega nerd

bright hill
#

If i didn't get the best mark in fucking economics

neat frost
#

Lame!

bright hill
#

I literally studied economics for 2 hours that semester

#

How.

neat frost
bright hill
#

Literally how.

neat frost
#

Because you self studied a lot

#

Also you're a mega nerd.

chilly hull
#

self studying is the king of college prep

cyan goblet
bright hill
#

I didn't self study much

chilly hull
#

like

neat frost
#

Okay DarQ your uni is full of idiots

bright hill
#

I haven't even finished a single book I've read uhhhh

neat frost
#

What is supposed to be said?

bright hill
chilly hull
#

self studying is awesome

cyan goblet
#

self studying is not how many pages u read per hour

#

it’s how many hours u spend per page

#
  • someone online or something idk i heard it somewhere
neat frost
#

Anyway this is a lame convo

#

Wanna see some TeX weebery?

neat frost
#

You're all nerds

neat frost
#

SOME2 LOLOLOLOL

bright hill
#

I studied math for about 374 hours this year

neat frost
#

"let's make a video this year! It'll be great!!!"

bright hill
#

That averages to about 1 hour a day

neat frost
#

What was the idea again? I forgor

bright hill
#

People can manage that.

neat frost
neat frost
#

Most people are not studying every day

cyan goblet
#

since uni i study about 3 hours a day minimum

#

that might be a bit low actually

neat frost
#

Nerds!!!!

cyan goblet
#

but also four math classes so

#

i dont have much of a choice

bright hill
#

I wish i had 4 math courses

sick kite
bright hill
#

I might have to fucking study then

sick kite
#

dar cube why can't you self study other shit if you have spare time

bright hill
#

Sigh, i am

fringe needle
#

i came into uni fully expecting to get shit grades because my only view of other people doing math was on this server where most people are a good deal better than me

#

and it ended being the complete opposite

bright hill
cyan goblet
#

first year uni students

#

especially business majors

fringe needle
#

it doesnt mean the uni's shit, it just means i had an advantage cause i had done some self studying beforehand

cyan goblet
#

would maybe average 2 hours per week

fringe needle
#

well ig it depends on the uni

cyan goblet
#

and major ig

sick kite
cyan goblet
#

idk a lot of my peers rn dont study a lot

sick kite
#

like if I get 2hrs self study done in a day that's a really good day

cyan goblet
#

and theyre mostly stem

sick kite
#

I only got 1hr done today and It wasn't super high quality

fringe needle
#

but at least in my experience the average stem student studies for more hours during the week than the average adult works

cyan goblet
#

hmm

bright hill
cyan goblet
#

idk about first year undergrad but id believe that for later years

neat frost
fringe needle
#

(when i say "studies" im including scheduled class time of course)

cyan goblet
#

oh

#

ok that makes sense

sick kite
fringe needle
#

there are plenty of passionate people at my uni who are currently redoing first year

bright hill
#

Classes are mandatory

#

I skip classes when I can but that's about it...

fringe needle
sick kite
#

mhm

fringe needle
#

but then again this is just my experience of it i by no means have an objective outlook on the average stem student across all unis

sick kite
cyan goblet
#

imo studying is one of my great pleasures of life

chilly hull
#

40h a week sounds doable if i carefully manage tine

cyan goblet
#

like what is more fulfilling that expanding your knowledge

sick kite
chilly hull
#

same

sick kite
#

then the progress comes all by itself

cyan goblet
#

the ability to pursue knowledge is a blessing

sick kite
#

its the same with triathlon which is a hobby of mine

#

I enjoy running, swimming and cycling by itself as a means rather than looking for the goals of faster times, for example

#

and faster times come by themselves

chilly hull
#

i want to reach the point where i can start PDE theory

#

sounds fun

sick kite
#

I have quite a bit of time before I can start even considering pdes

#

but lots of fun stuff inbetween

chilly hull
#

i have a lot to do before i can start pde theory

#

functional analysis

#

measure theory

#

multivar analysis

sick kite
#

it will come in due time im sure

chilly hull
#

i think some point set topology

#

idk

bright hill
#

Have found none so far doe

sick kite
chilly hull
#

darq what math class is it if i can ask

solid snow
#

At that point just take the university class(es) lol

bright hill
#

And a of them watered down

chilly hull
#

could i smash the analysis class

bright hill
#

Absolutely

#

Like, the only group theory we did in algebra is the definition of a group and the definition of a subgroup LOL

chilly hull
#

wtf

bright hill
#

Same goes for ring and field theory

chilly hull
#

i dont know much algebra

#

all ik is what a group is

#

an abelian group

#

i think what a ring is

bright hill
#

Oh, yeah

chilly hull
#

and what a field is

bright hill
#

We defined abelian groups too

chilly hull
#

would an abelian ring just be a field

bright hill
#

No

sharp mulch
#

?

bright hill
#

Also, abelian rings aren't a thing

chilly hull
#

i know

bright hill
#

It's just called a commutative ring lmao

sharp mulch
#

Lol

chilly hull
#

i was thinking something weird

tall badge
bright hill
#

Yeah, so

neat frost
#

So what did you do in algebra then DarQ?

chilly hull
#

oh right i forgot inverses

bright hill
#

Uh

#

Other than that

#

We started with a semi brief intro to proofs

#

Polynomial rings and polynomial factorization in C and R

#

Bezout and gauss' theorems

chilly hull
#

idk much about algebra so i cant say much about this

bright hill
#

Fundamental theorem of algebra (which we didn't prove)

chilly hull
#

what about analysis stare

bright hill
#

Analysis is just calculus

#

Literally

chilly hull
#

seriously?

#

like

neat frost
bright hill
#

Yea

#

We did calculus in hs

chilly hull
#

not even epsilon delta?

neat frost
bright hill
#

And IG this is just harder calculus

bright hill
chilly hull
#

ok nvm

bright hill
#

It's SO dumb!

chilly hull
#

does the material look more like spivak calc

bright hill
#

Ughhhh

chilly hull
#

or something like stewart

bright hill
#

Haven't read both of those

#

What's bugging me is that my classmates are struggling

neat frost
#

So help them

#

Also I forget do you have a plan to transfer next year?

bright hill
neat frost
#

I understand it

bright hill
neat frost
#

When do you plan on transferring?

bright hill
#

Next year

neat frost
#

Yeah okay

bright hill
neat frost
#

Do you know what happens to your credits if you transfer?

#

I'd start looking into that, because you may not be able to keep all of them

bright hill
#

It's gone

neat frost
#

Ah

#

Well

#

Is there a way to transfer them?

#

Maybe taking some courses with the future uni even now?

bright hill
#

I dunno, i doubt it

#

I'm technically not even in a uni

#

Anyhow, i shall continue my rant

#

I genuinely think I might've been more interested in math and academics in general if i had peers that were equally (preferably more) interested

#

And i thought i might reallyy have that once i entered uni

#

All I've seen so far is disappointment

sick kite
#

Darq i know you are frustrated but you need to understand that a math degree doesnt immediately imply that everyone loves pure math

#

many probably do it for better job opportunities

#

the time will come for communities which love pure math

#

probably when you're a grad student

neat frost
#

I don't think he's saying that he expected everyone to

#

Rather that he expected to be able to relate with at least someone/some people

bright hill
#

Ye

neat frost
#

I think you're totally justified btw

#

Again, move here 🥱

#

So if you do move here, don't go here

bright hill
neat frost
#

Also don't move here

#

This is my territory

bright hill
#

Problematic

neat frost
#

If you don't beeeeliiiievvveeeee

#

Also don't move here for other reasons

bright hill
#

And it's not that my courses are too hard btw

#

I think they're objectively manageable

#

It's just that my classmates are lazy

neat frost
#

I get what you're saying

bright hill
#

And uninterested

neat frost
#

Being lazy is a trait I respect

bright hill
#

I don't say that lightly or speculatively at all

sick kite
#

Jesus. You're in first year. I'm sure that as time goes forward the amount of interest in the subject will increase

bright hill
#

Doubt

sick kite
#

It's hard to take difficult courses without at least some interest, and because students will inevitably take hard courses (and do well) in the later years, that implies that they will have at least some interest.

bright hill
#

Hopefully

mint canopy
#

Some people are interested, and some aren't. It can be easy to believe that, when seeing the uninterested people all around, you're the only person who cares – however this is a dangerous trap to fall into!

It is true that most undergrads (especially in first or second year) are not particularly interested in mathematics and are probably there just to get a degree. However you must not dismiss the people who are interested, but you may not be seeing. In fact if you're doing a Master's degree, you will come face-to-face with these people very quickly. Never assume that you're the smartest person in the room, and especially not in a crowd.

neat lintel
#

In my class nobody is interested enough to enroll in a Mathematics Uni.

#

it's rare to find those people that really fall in love with mathematics that much to just do entirely that for their life. Most of us in class, and people from other classes can enjoy maths, but not to the point of only doing math exams for 3 years.

some people told me if you read a mathematics bachelor degree, it will have a huge impact on your future career and research, I believed him

fading moon
#

I wish I chosed to pursue the CS degree

neat lintel
#

One can't have everything.

#

I'm sure that mathematicians can get into CS and programming stuff on their path tho, many do.

#

If I want to be honest with you, my parents also tried to convince me to take CS or Comp. Engineer in the past because I always had 100% in CS subject from the first years of HS.

#

But I made the right choice and rejected both engineering degrees or CS offers.

Don't wait too long. Also just remember that people are usually likeable once you get to know them a bit

alpine kindle
#

yeah

#

I'll keep that in mind for uni

neat lintel
#

Same

neat lintel
#

Some people are really better not involving in your life, especially in HS

mint canopy
#

This much is true

neat lintel
#

There's a lot of people that are in HS just because their parents put them there and have no intent pursuing any further studying, and only disturb lessons.

The way classes works in Italy is that you keep the same classmates for all subjects for 5 years, so I know them too well by now.

#

I think there's just a big transition between the quality and quantity of people you can meet in HS and University that can have positive outcomes in your life.

I went to one of these math events in my city this year which had a theme of "modern math for school and early university students" and it held up to that theme because there were many active researchers giving lectures and some of them are also professors at country's best universities

frankly it was kind of eye-opening when I was the only one who raised hand when the lecturer asked "who doesn't know what a projective plane is?"

I'm debating on how much to charge for tutoring and I'm curious what you guys think. I've been approached by a mom looking for tutoring for her high schooler in geometry. I've worked for my university as a tutor for 3 years, I'm finishing up my masters and I'm certified as a level 3 tutor through the College Reading and Learning Association.

I'm thinking about charging $30 for an hour remote/they come to me or $45 for an hour I come to them. Do you guys think this is a fair rate, or am I under/overselling myself? I don't want to rip people off but I also want to be paid what I'm worth.

vivid halo
#

that's fair yeah

#

maybe underselling a little at 30

neat lintel
#

I can’t help. I do pay tutors but it’s a different country and currency

iron leaf
#

I currently make $15 an hour at my university (low, but consistent) and $50 from another high schooler (they offered that rate to me, i come to them)

neat lintel
#

I pay around 20€ an hour for receiving in person tutoring from a Physics PhD, but I’m in Italy

if they say it's too high you can negotiate down

I'd do 60 for them visiting you, 75 you visiting them

peak tide
#

people get paid like $20/hour for flipping burgers these days, seems you should be able to get at least double that for specialized skills like math tutoring, but it's all about supply/demand where you live

static loom
#

part of it is getting over the uncomfortable aspect of negotiation, any kind of self esteem/sense of worth you have, among other things. For instance, if you charge more, the perception of your service by them changes as well. For instance, if someone pursuing a phd or masters in math is charging a cheap price for a lesson, it makes a regular person think they're some kind of dropout or something, and providing a sub par service.

I’m honestly really worried by my country economy right now. Especially because I want to become a university student and I do expect to be rewarded properly after all those years

river moon
#

well everything in the US is expensive compared to most other countries so the paycheck needs to account for that

#

usually you'd have cheaper things in local currency than what you'd get in USD somewhere abroad

I just hope in the future my degree will be worth it for a good job, and my best friend too I’m concerned for her

i have once asked the question in some help channel to help me in understanding lim sup thing

no one helped me but i figured it out eventually

however i started feeling like i'm lack of knowledge after understanding it

i'd never seen that before i did read the quantum computing book

are lim sup like the ones ending in 1-

Gradient flows are fun little objects. A way to think of them is to consider the ode (I’ll neglect initial conditions now yadda yadda)
[\dot{x}=-\nabla E(x)]
Where $E$ is “nice” (convex, lsc, etc.)
If you recall the simpler ODE on $\mathbb{R}$,
[\dot{x}=-x]
has a nice solution! It’s $x(t)=e^{-t}$. So here, we actually have found a gradient flow in disguise! If we let $E(x)=\frac{1}{2}x^2$, we see that $E’(x)=x$ so we just solved $\dot{x}=-E’(x)$.

Now, what does this mean? Well… Gradient flows in turn have the goal of giving you an idea of what minimum values of $E(x)$ are! So if we recall our solution to $\dot{x}=-E’(x)$, $x(t)=e^{-t}$, we see if we let $t\to\infty$, $x(t)\to0$, and in turn, we notice that [\lim_{t\to\infty}E(x(t))=0!]

They do not need to be conservative (if I have read about Wasserstein gradient flows correctly)

I think the fun thing behind the scenes for gradient flows is there is an intimate connection with geodesics

My great grandfather (still living) was a chief engineer at NASA during the space race, and personally worked on Skylab. I've been granted the great opportunity to see the original documents and notes that were taken during the creation of Skylab as well as a list of all the active engineers who were under my Great Grandfather. It's one of the biggest inspirations for me to pursue a career in aerospace engineering and for me to pursue a math heavy career.

I wonder why these two are wrong.
Maybe someone who likes Collatz can come up with a refutation for those two.

What's really funny is I created a thread asking about the first one in a different mathematics server. I gave up after finding their induction doesn't work, that one of their variables (I think it was m) doesn't make sense as an integer even though it's used as one, etc.

I haven't looked at the second one yet, I want to take a closer look

So I'm still reading this but already I'm seeing possible problems here

  1. You would need to know that the sequence is referring to positive numbers. You can do a "division sequence" starting with a negative number as well, so you should be careful doing these out of context.

  2. Also, while I don't think it's a huge issue here, if you're not careful you may not know it's the 4-2-1 loop. Supposedly, a sequence of 2,2,2,... etc may not actually be the 4-2-1 loop but something else and that would need to be proved.

no one who knows any math will ever care about collatz tbh, thats enough to know its crankery

I think this is the "definition"?

do i need wew to tell me this is crankery? I think not.

dim needle
#

If we're talking about the "division sequence" of n, that's just its trajectory. Most numbers don't have a trajectory of 1 or an empty set???

#

This is... not a proof

I proved Collatz. I just defined a new field of mathematics where it is an axiom

dim needle
#

I'm so glad I took logic and algorithms, I finally have a chance of understanding this stuff

light needle
#

#

#

I don't think that's how induction works

#

I haven't proven why this proof is wrong yet and I more or less already lost my patience. I guess the real skill I need to develop is that at this point

long matrix
#

why do u need this

#

reading wrong math isnt what a mathematician should do sully

dim needle
#

I personally want to prove the Collatz Conjecture myself, and I don't want to write a garbage proof. I'm expecting that if I ever think I have a proof, there's most definitely a problem with it and I bet someone at a university tutoring center can spot the problem with it

long matrix
#

the proof being written garbage or not is secondary

#

coming up with the relevant ideas to prove it is primary, and i dont think this hurdle is likely to be crossed.

dim needle
#

I'm not a mathematician, I'm not going to expect my first attempt at a proof to be very good 🤷

long matrix
#

I feel like you're missing the point.

#

The point of the proof is to convince everyone else

#

but before that - you first have to convince yourself

#

ie. prove it to yourself first

#

Can you? I doubt.

dim needle
#

I'm assuming just because I think my proof makes sense doesn't mean it actually makes sense

river moon
#

collatz conjecture is one of these problems that nobody in their right mind would bother checking the validity of the proof for

#

it's fermat's 2.0 and that still runs with people "coming up" with simple "proofs"

long matrix
#

at least one can see how fermat's still has some mathematical relevancy

dim needle
light needle
#

the path to fermat like led to the devolopment of many good tools that are more interesting than fermat

#

its certainly a more relevant and useful problem than like

#

collatz imo

#

by a long shot

vast surge
#

But according to some guy on reddit collatz led to (p,q)-adic analysis, which is useful only in that it's equivalent to collatz, so therefore collatz is just as useful as fermat

I don't know what your mathematical background is.

'not a mathematician' doesn't make it clear

My mathematical background is I have passed Calc 3, dropped out of Calc 4, I just recently took logic and algorithms, and I spent a lot of time in tutoring for the first two weeks before dropping def eq because I struggled hard

I really like math, but taking higher level math in college is both incredibly stressful for me and demotivating. I'm a computer science major and I like the idea of teaching myself higher level math concepts over time

Would you be familiar with the contents of an intro to proofs course

#

If yes, then at least you should have the foundation to be able to write a proof properly.

If you make your background clear on mse and/or ask people to elaborate on their answers (or point you to some reading), it shouldn't be an issue

is like basic here.

I used to play hours every day, but I played a lot less after I met my gf who hates it

#

I got this mail with how much I played in 2022 recently and it said roughly 200 hours, so about 0.55 hours a day

#

Now let's just make that number 0

I've done nothing except watch Youtube videos every single day after high school for hours.

#

every single teacher had a problem with me being distracted

#

for me, I'd say that it's crippling, because I missed out on literally everything
