Yeah, it helped a lot! Good night!

what does offset mean here 
oh its the relative memory position relative to the register address
Is the time column for liek
How long until the next letter
what are a,b,c
yup
they represent what stuff I'm doing together so a/b is doing a and b at the same time/there is some overlap
That being said, I'm revising that section because at the rates and diversity of the things I've specified, the only way it's possible if I don't sleep at all for 2 months straight 
does anyone do foundation math?
Bro can someone help me and explain vectors to me, please
those in #foundations do
vectors are column matrices
well vectors are elements of cartesian product R times R or if youre in 3d R times R times R
okay so do you always have to follow the (x,y,z) ?
that's their form in 3d
yeah cause of z
if youre in 2d they are of the form (x,y)
okay can there be more than z
sure
an n dimensional vector is an element of the cartesian product of R with itself n times
R times R times ... times R for n many R
R is set of real numbers
look up set cartesian products
ohh okay i just did, thankss
but than how could there be more than z ?
can it be something outside of 3d ? would that even work ?
like hypothetically can we go beyond 3d ?
in generell ?
Wiener processes caused me mental breakdown
yes and we do that often
in vectors too ?
For example your vectors could represent the position in 3d space of 2 iceballs. So you need 6 coordinates to represent them. Your vectors will be the elements of a 6d space
ohh okay so then do you go beyond the "z" which is in 3d or do you still keep it and continue using it by going ahead with the cartesian products
might be useful to use variable names like x_1, x_2, ... if you use a lot of coordinates
elements of $\mathbb R^6$ could be written like $(x_1, \dots, x_6)$
Carla_
I really like this explanation, especially for beginners. Makes it clear why we might want more than 3D vectors without getting tripped up on thinking of how we only live in a 3D world
okay so how would you connect this to our dimension that we live in
doesnt matter
you can have extremely ‘long’ vectors for example that represent the stock prices of a bunch of companies for example
with each entry being a different company’s stock
you can also have vectors which arent even vectors in R^n
for example, considering continuous real functions as vectors
surprisingly stuff that lives in high dimensional space has direct interpretation in 3-dimensional world
just because we live in 3 dimensions doesn't mean that it's enough to describe everything
e. g. you can take any object and assign it 10 numerical values that would reflect some of it's properties
sort of
It looks like a phone
it looks like a radio
it looks like a nintendo switch
Always wanted to know the basis of this
But they tell me it’s too complicated
Smh. Government
With “…”s Right
Zemon 
yeah i dont think theres any formula that uniquely defines a basis for it (in all models)
So you cant know a basis of it. You can only know some (infinite) sets of basis of it
Can someone give me something to read so I can sleep
Something interesting but hard to understand or boring and hard to understand idk I needa sleep
read umineko
Is it a sci-fi 
Well I don't think I'll be able to find it
One I found online and it's Japanese
read a canadian book about politics
it makes you sleepy like in 2 minutes
hartshorne algebraic geometry
Perfect, give me a name
What video games do you guys play?
Depends on why you ask
you can find one if you search
I'd recommend playing geometry dash
I decided I'm not gonna sleep for some time xd
what time it is rn?
00.00
for school?
Uni

@solar hawk moving here to not clog up the other channel: where did you learn LA from?
Axler?
ya and bronson
so
well
ok its werird 
i learned vector spaces to fish theorem in axler
but also matrices and vector spaces to eigen-stuff from bronson
and then in general some R^n computational engineer bullshit from whereeverelse
lmao
lmao
So you’re good with linear maps and stuff?
yah
how much inner product stuff did you learn
if not then there a big problem 
not much
or maybe i just forgot it yk.
ofc i remember the dot product from this
integration on the function space too
I need to know how much you know so I can see if I’m gonna be able to follow ITM with you lmao
you know inner product spaces right
eh.. I guess?
I wouldn’t call myself fluent
improperly i wanna learn it right from a book
which would be axler
but im reaaally behind on my problems
so i aint wanna do it anymroe 
wait, you don't solve every single problem?!
i do
which is the problem 
its gonna take
oh
forever 😭
well
i didnt used to
but i do now
so ye

Bronson and Axler had lots of overlap though
For simple problems I just do them in my head but usually it just takes around an hour though
and i did all my Bronson homework
ya
matrices, and all that
doesnt do fish iso, afaik/r
it does do diffeq
fundamental form and stuff
ngl i completely dumped that from my brain tho 
ahh, I might just get it then, cause gilbert's introduction is a very beginner level intro ngl
I always have the urge to, but am never able to lmao
Bronson is also pretty intro
there is a uni-hosted PDF online
so u can just read it from there
it also depends on the number of problems, like I ain't solving 89 or sumth problems from gallian 
thanks
fair
How do i choose an area to do undergrad research in?
Just follow my intellectual interest?
maybe
cat cpr?
Yeah, i can choose between optimization or graph theory/the travelling salesman problem. I think i'm gonna go with the second one
:o
Looks more fun
completely unrelated to math, but is anyone available to help me with non harmonic tones and 4 part writing for music theory??
off topic but what do you guys think about Devin?
who tf is devin
He's gonna put the money in your pocket
Hello everyone
Hi everyone, I am looking for a learning buddy. I am studying DE from the Simmons (DE with applications and historical notes). Is anyone interested?

Well, I'm back.
This is probably the best birthday present I could have asked for, even if it came a day too late. 🙂
happy late birthday
Thanks.
Yknow parametric curves aren't so intimidating anymore after looking at it for long enough.....
welcome back 
Thanks.
If you're starting a study group count me in 
wait, is my defination of differentiation correct?
there's a function of x which is giving us the value whch we are plotting on the y axis
so, the value of f(x) or y which we get when the difference between 2 value of x is 1 telling us by whaat is the value of f(x) the graph is moving
can we say that the process of finding that value is differentiation
Differentiation is the process of finding the derivative. The derivative can be interpreted as the rate of change at a point or the slope of the tangent line to a point.
how can derivative be the slpe of the tangent y
the slope of a line drawn between two points $(x, f(x))$ and $(x+h, f(x+h))$ is given by [\frac{f(x+h)-f(x)}{h}]
Namington
do you see why this is true?
its an application of the slope formula $\frac{y_2 - y_1}{x_2 - x_1}$
Namington
just replacing "y" with "f(x)" and "x_2" with "x + h"
the derivative, then, is the limiting behaviour as you make this distance h small
hence giving you the slope of a tangent line at a single point
i.e. $f'(x)$ is defined to be [
\lim_{h\to 0}\frac{f(x+h)-f(x)}{h}]
for $f\colon S \to \bR$ with $S\subseteq \bR$
Namington
i would caution against talkin gabout "x" and "y" axes
since we often differentiate with respect to different variables than just x and y
the derivative is an operation on functions, not on graphs
graphs just give us intuition
for example, newton's original formulation of calculus only considered time derivatives.
What happened?
I was banned for two years. 😭
out of curiousity, how did you manage to come back?

@hollow sun 
Question: will I die if i take advanced linear algebra and real analysis in the same semester
You'll die either case
Would you recommend taking probability alongside adv lin alg or real analysis then?
Sorry to ping
no
what kind of probability
what other courses are you taking
I will be taking like 2 social behavioral/humanities
- im planning 2 math
And one extra (linguistics) if i can handle
I was originally planning real analysis over the summer in a month. That definitely doesn’t sound fun.
that totally depends on your math background
This is a lie. Real analysis grants immortality
You are now obliged to become a discussier
At least, this is discussion-2
This place is, as far as I've felt, not at all like discussion-1
#discussion can be a real mess sometimes
Yeah
It all connects in the end
Can someone resolve some doubts i have about AP calculus AB?
what do you need?
!help
To ask for mathematics help on this server, please open your own help channel or help thread. See #❓how-to-get-help for instructions.
No it's not like a mathematics question
what it is then
I got an email about the terms and conditions of the AP exam and was told in the email that i needed to accept those terms in order to give the exam
when i went to the terms and conditions page there was no checkbox or agreement submission button
when i attempted the digital SAT, i received a similar email and accepted the terms on the webpage
so i was wondering if since the AP exam is on pen and paper will i have to sign the terms agreement at the test center on paper?
honestly im not sure
what is the difference between a function and a variable
Variable is the input of some function
so it was defined to be solely keeping in mind that its eventually gonna be an input to a function
Usually but that's not necessarily defined explicitly
Ig i can say x is a variable without ever mentioning the function which deals with x
But the point of defining a variable is mainly to have it as a placeholder for something with a specified structure and whatever expression the variable appears in will be its function
That's how I'm familiar with it at least
i LOVE the way youve written
isnt function also a placeholder in the same sense though
@proud olive
It can be but it can also act as a pandora's box
so function is variable + pandora's box
Yeah if it hasn't been defined yet
But well function and variable are kind of hard to distinguish between tbh
variables are simply just placeholders for whatever we choose
But what I mean by this is that it can still give you outputs even if you don't know its "framework"
But if you've specified the inputs then the outputs must always be the same
hmm, its like i dont know what the operation it does but i know enough to say that it does SOMETHING and if the operation itself isnt important for the part of your work, you can abstract it out with whatever you want
the graph of a function $f : X \to Y,: \Gamma_f$ is a subset of $X \times Y$ with the restriction that for each $x \in X$, there is only one pair $(x,y) \in \Gamma_f$
josemom2
this, along with the domain and codomain, encodes all the information of what a function 'does'
i.e you can describe it entirely by its inputs and outputs without touching the guts
can someone tell me really quick how to calculate chances? Do you calculate the percentage chances by dividing 1 by the other number, for example 1/450 if i divide 1 by 450 do i get the percentage
you multiply that by 100 to write it as x% where x is a number from 0 to 1
can u give me an example i dont understand u
multiply what you just said by 100 to write it as a percentage
can u check dm
no
bro come on i dont understand what ur saying
multiply what exactly
1/450
how do i multiply that
how do you multiply 1/450 by 100?
(1/450) * 100
is the / divide
Yes
ok thanks
And * is multiplication
I need help right now
how does dot product of a 2d plane with another side gives you volume
How do you guys recommend studying? Do you recommend to just follow the notes my teacher provides to the students or should i follow the book? Maybe both?
Mathematics in general
Undergra
d
Yeah what?
So when would i know to supplement?
I se
e
And just rewrite the theorems the notes present and stuff?
The definitions as well, i presume?
Isn't that quite time consuming though?
Gotta know how to balance things i guess. If there is just too much gotta rush a little faster and some things can't be rewritten
Is that it?
I see
I usually use anki for this kinda of stuff
Yeah
It supports latex
are you gonna go further in maths? undergrad degree? grad school? etc.
But it's best for definitions since there are usually a lot of them
do you want to understand stuff or just to apply them
Yeah, i hope to do a phd
Understand
Yep, or tcs
But my country is a little inflexible so it'll probably end up being math
ok, then prove every theorem and formula. Don't just read the proofs. Try to do it and take a sneak peek only when you are out of ideas, and try again.
I see
this is something I can only recommend to serious people
Gonna try starting to do it
Hope i don't use all of my time trying to prove theorems
Nah, i'm just beginning
It is, and that's how maths will be even up to research level
Starting to get introduced to proofs
the theorems are just the signposts on a map
you have to undertake the real journey yourself
Yeah, you're right
any textbook can give you the solution
none can tell you how to find it
I think i just don't manage my time very well and spend too much of it doing exercises i already know how to do
exercises are less important than proving the main theorems and formulas
I see
they are just there to make sure you didn't fake your way through the book
Will start slowly adopting this practice
So as to not crash and burn
What is your instance on definitions delerik? Should i just memorize them?
I can recommend reading Lang's Basic Algebra and then Tao's Analysis along with a good book in linear algebra
People say kunze is good for linear algebra, i can tell it's very rigorous from skimming it so have caution
yeah kunze should be fine if you can handle it
if you need help with proofs or have not seen it before, read "How to prove it" by Velleman
"Don't just read it; fight it! Ask your own questions, look for your own examples, discover your own proofs. Is the hypothesis necessary? Is the converse true? What happens in the classical special case? What about the degenerate cases? Where does the proof use the hypothesis?" -- Paul Halmos
same for definitions, give examples and counter examples
Anki is for recalling stuff years down the line. understanding alone can go for a long while before you need refreshment from flashcards
they are all super obvious once you know the complex exponential, but sure you can practice with them
though they are mainly about calculations rather than logic
Thanks for the advice delerik
yeah
nice
hey

Tf, I wonder why I even have to bother about my appearance IRL meh
Why are everyone in my region so obsessed with it
i like your profile picture
Why sully
I think proper cleaning and self- care is good, but people in my neighborhood pretty much constantly talk about good looks. Bleh
Yuck
Appearance shouldnt matter as much as we make it
Its just such an unattainable goal that we all are told we should strive for
I am not wearing a suit to my gas station interview sorry
Wait what, suit to gas station interview?
Oh god
I was making a joke mostly, but...
Ah, sorry
Anyway, I cannot agree more.
Well you dont make it
It just is
Ok, im using "we" and "make" pretty loosely there yeah
But im not about to explain the way that ideas spread and take dominance
Sooo
Yeah
You only have to wear something nice
Yeah formal attire is fine in reasonable circumstances
Most are reasonable circumstances
But if its a friday afternoon you best believe i am wearing a tshirt to my job
Wish people just care about attire instead of appearance itself, meh
To the job you just wear something nice
Yeah ik
I dont know where thatl be but most jobs dont require a tie
Let me put it down for you, dress to impress, first impression is everything,and going loosely makes you seem inexperienced or not commited enough
Yeah ik, i can follow rules without liking them though
After you get the job your going to need to wear gas station clothes for it to have effect
Lol
True, first impression matters
(But well.. suit for gas station is still)
It would be funny to show up in a suit ill admit
I think youd get extra points w the employer for having a sense of humor
Unless its an advanced company even local brands are fine
Ahhh, ye indeed
You dont
Damn
Interviewers take many applications and take them very seriously
Your joke needs to be hilarious for it to not have negative effects
I think demonstraring a sense of humor could help you get a job, it makes you stand out
From their side your nervous
Well not if you pull it off right
Not many people can
Especially under judgement
Even if you pull it off your going to be sweating from the pressure
I know some people who are just, cool as a cucumber no matter what, its nuts
But also if its a gas station or smth u arent gonna be that pressed if ur rejected
Theres like a billion other places
Now for a more professional job, yeah
Yeah no not there lmao

i try to use my credibility as a large server owner to pass on ban appeals i think are appropriate, since i'm not the one in discussion it makes it far easier
i do have to admit discord could put its own resources to make ban appeals easier for both the banned user and the moderation, but what difference do i make
water beam
yajat
do you remember me?
The physics guy?
what physics guy?
yes
theres a such thing as overdressing causing you not to get a job too
its totally not too common
Indeed, it does not seem appropriate attire
but sometimes people want someone who isnt just forcing confident presentation w a faccade
so it depends
(Unless for jokes)
but a casual suit is very smart for anything like
light business casual
not business formal
You can overdo it so much that it works again though, 2 different dishwashers have shown up in suits at places I’ve worked and they both got hired just for the sheer shits and giggles of it
true
just gotta know your crowd
for any job in my profession especially w the consideration people find gauged ears dickish looking
I wear suits
and am very very well educated and well spoken so luckily the style I present does not infract on my ability to make it very evident how smart I am and how qualified I am in an instant regardless of how i look

Hello everyone, I would like to ask a question . I'm particularly interested in automated theorem proving, especially Lean4 and its mathlib ,is there any community, people on this server or any other server that discusses related content?
Hey tteppa

If you’re in high school, can you test out of math duel enrollment courses like a college equivalent of like an AP test?
it is only for active users like active/very active/emeritus
and postgraduate math iirc
you can
damn
Does anyone have advice on how to generally get better at math?
Per se, how many hours of math studied every weekend/weekday, and which programs helped the most? i.e. IXL, Khan Academy, YouTube Tutorials
taught me lots of stuff
set yourself crazy problems that you know you can’t do and learn new math to solve them
paul's online notes
I used to spend entire days ~16 hours studying
I would recommend you do that
Learn vv fast
it's not about the hours
the first thing is you need to somehow learn to enjoy the suffering journey
then time flies when you do math, and before you realise, you cannot stop
there are good programs, but idk any that fits everyone
you just have to try a bunch of ways and see what sticks
I have very hard time learning something if it's not something I care about. so usually I find some stupidly difficult but seemingly approachable problem, and learn whatever it takes to solve it
In highschool or college?
but how
Are you passionate about math in general, or forced to do it lol
I dont have the mental nor physical capability to study 16 hours a day
don't count by hours. just spend as much time as you want until you understand something
but you have not told us your level so I assume you're pre-uni
in which case, all the more, you need to be honest to yourself whether you understand something. any gaps will just come back and bite you harder.
I have a bad foundation, but my math course in school goes very fast, do you recommend going back to build stronger foundation or study the upcoming stuff first?
see this is the problem. because you have gaps, instead of solving one math problem, you're solving two. And you don't even know what the second problem is.
college
I think I would had spent more time studying if I didn't do 16 hours a day
what I really recommend is to plug the gaps in your understanding. which requires complete self-honesty. you can do it yourself or you can ask a tutor or friends or the teacher to check your understanding. there should be such resources
WHY
100% just do the upcoming stuff you have no idea how to do /j
This is the best part lmfao
@gloomy bobcat you should both do that while trying to keep up with class material. don't be too afraid to ask the teacher for help who knows your situation best.
Ok, thats what Ive been trying to do - but I am also a very dedicated pianist so that takes away lots of time lol
I entered in the middle of the convo but why not work for 4 hours and get the productivity of 16 hour of studying? I mean, some people pass others this way and this got reccomended to me as well.
Also I need to stop procrastinating and set schedules
maths is rather fair in its returns. it's just how much you want to invest in it
Yeah, for formulas I have terrible memory, how do you recommend memorizing them? Like would you say writing them down, repeat it in your head, do this a few days until you get it entirely is effective? The formulas done this way are usually forgotten a few weeks later though
do you understand why the formulas are true
understanding from first principles rather than memorization is why as a kid I vastly preferred maths / physics to bio/history
latter is a lot of memorization
former is just thinking from first principles so you only need a few core things to derive the rest
understand the formulas, apply them in exercises to get a feeling for them, and you will retain them in your mind for a long time
So you find math interesting, maybe as such a hobby? Is that your motivation to continue doing it and doing well
Do you think coming back to them occasionally helps or just for a specific period of time is fine
I don't "come back." I just get alarmed if there is something I don't understand or can no longer recall. Then I relearn and each time I do it I do it much faster and with new perspectives.
For instance, do you know Pythagoras theorem? a^2 + b^2 = c^2
why is that thing true again? if I find myself not understanding something I think about it immediately
I study for tests and formulas, and seemingly forget it right afterward because our teacher moves onto another topic of math and seem to never review the past topics
So I have no, motive I guess
at different stages in life I have different motivations
competitions, prestige, deadlines
those are extrinsic factors. but the longer I spend in maths the more I realize the intrinsic reasons
figuring out why things works is fun. That's why people love puzzles, science / trivia videos etc.
and mathematics is one of those things that only become more interesting and mind-bending the higher you go. it never repeats and keeps giving you new mysteries and quests to overcome
and whenever people ask why do it, I can just unironically say I want to understand the universe
I can't imagine living my life without understanding how quantum mechanics or general relativity works, especially when they are amongst the greatest discoveries of mankind
I can see where you’re coming from, and I think I just have a bad relationship with math from the start, and I assume your interest in math really helps with motivation, and everytime I study math or look into it I have this depressed feeling of not getting anything, Lol.
good thing is that maths is about the only subject where you can understand everything to the smallest of levels
Math is extremely logical, too logical. . .
logic is only the mechanical part, like typing on a typewriter
and yet writing isn't about that mechanical part. you have to tell a story
And in maths you have to find the right ideas and directions first before you can verify or calculate. and then make it a coherent story, like the theory of unbounded operators. that is an art.
https://en.wikipedia.org/wiki/Mathematical_maturity#Progression
see the post-rigorous phase of math
In mathematics, mathematical maturity is an informal term often used to refer to the quality of having a general understanding and mastery of the way mathematicians operate and communicate. It pertains to a mixture of mathematical experience and insight that cannot be directly taught. Instead, it comes from repeated exposure to mathematical conc...
i love that article
although
oh there's a wikipedia page for this? i immediately went to tao's article lol
tao was explaining there's more to math than rigor, but ironically i tend to cite that article to people who lack rigor, since they are not necessarily even aware of the "rigorous" stage
you have to go through all 3
i'm still at the stage where i write down a problem and get stuck rephrasing it in useless ways
which is probably stage 2
Never thought of it that way, and now I think about it, in a form thats true but its difficult to do so lol
Did you take calculus AB or BC in highschool? Did you find it easy if so?
Or hard at first, easy later on?
I found calculus rather disappointing because half of it was unproven memorization.
the college version called Analysis is where you prove everything
and it's somewhat magical, since before uni I had been using real numbers without knowing what real numbers are
like, such a huge gap I didn't recognize I had for 18 years
that gap accounts for all the magic in calculus
anybody have advice on evaluating the quality of an undergrad math program? what should i be looking for etc
i need mathematical maturity so i can become a math milf
I get confused when I read proofs written by ChatGPT
we all do
That’s because they more than likely don’t make any sense

What
that message makes me feel several emotions concurrently

here too lol
Math milfs is one thing I never thought I would hear in my life
But alas
This is a hard question to answer based on many factors.
First, what country are you even in
Second, do you have the freedom to apply anywhere or are you stuck locally?
Three, what schools are you interested in
Four, what cities are you interested in? (Remember school is only 1/3 of your life, if you move you're still spending 3-4 years somewhere)
Five, what is your current background. Any AP classes, SAT score, etc.
Once you narrow down your top 5-10 schools, either ask here or on reddit or something similar or just apply to them and see who accepts you and then come here to help on making a final decision.
Generally in the United States any R1 school is fine. Obviously there's some choices better than others (Ivy Leagues schools)
no fr I know who you're talking about
i've seen him
I'm going to start a chemistry channel on the hub and call myself "sodium whoride"
😳
Amazing 
This is a pun I'm going to keep coming back to and laughing a little harder each time.
Can you test out of dual enrollment courses while still in high school (like calc 3 or linear algebra)?
Test out in what way
Out of the college class for college credit? No
Can you do this when you’re in college though?
This is because I self studied a bunch and now I know like basic pde stuff and real analysis
Probably not a good idea in foresight
Still no.
You can do the CLEP exams, which basically means if you didn't get college credit for Calc 1 in High School, you can pay the fee and the the CLEP Calc 1 test and if you pass you get college credit for Calc 1, but for more advanced classes the answer is generally no.
I'm not saying it's never possible and never happens, but generally professors and departments want you to go through their classes their way, and if you already know the knowledge then it's expected to be an easy A for you.
Some places you can normally take a math placement test or otherwise taking an exam proving you have knowledge up to a certain math level, e.g. Calc 3
The department still sets guidelines that you're required to complete XYZ courses in order to graduate though.
That seems…
rough to people
lol
I mean, to be fair, mathematician in 17-18th century have been in the same boat for waaaaaay longer
like, even cauchy did that
and that was way into the 19th century
Just remembering that it's not long before I pass makes me panic, I don't know if I'll be happy or sad

@small dust Hey I deleted my messages. I crossed the line and didn't mean to make you feel uncomfortable. I'm sorry.
dw your predecessors have made me a seasoned veteran in getting uncomfortable messages. it takes a lot to make me uncomfortable
oh
Ooh shit you're green now
Looks good
Unfortunate, Layla
While I am making you uncomfortable just by existing
???
Every time I hear about messages you receive they seem to get just a little bit more insane, who the fuck are these creeps 
Have they never met or interacted with a woman before?
Salagos is usually quite tame
he's very fun to talk to
usually random people who have sent between 0 and 10 messages in this server
methinks he got possessed today or something
I mean, we get spammers fairly often who doesn't even seem to achieve anything
The world is surely mysterious.
Most of the random trolls are just edgy children saying random shit they don’t really believe to get a rise out of people
what salagos said is not even close to the worst thing i've received in the last 24 hours 

I'm not quite sure what happened with Salagos honestly
I've never seen him go off the rails once before
he goes off the rails when talking to me it's ok though
don't need to talk about it any more
Hmm, interesting
I guess we occasionally get the high effort troll
or the user who's not trolling, but may as well be
Daily dose of crankery.. ah, think we've not getting one for a while
crank in discussion 😌
oh right, you don't go to #discussion often do you Absta?
Yeah
Ahhh
there was also this today
#math-discussion message
Ah, so that was also a crankery
Probably the most frustrating thing about mathematics for me is getting stuck because I don't understand the specialized instructions required to use tool/technique X.
I feel there's a difference between getting stuck with understanding the tools and getting stuck with not knowing what tool to use.
I really don't like the former.
It's like finding out you don't have the right kind of batteries needed for your brand new toy.
not very confident, open to the possibility he's being ridiculous, not angry at the world over mathematicians not accepting his work
not a crank
I understand why professor have graduate students now.
The students can go research things to explain to the professor how to do X without having to learn all the details behind X themselves.
No he is not a crank
He is very open

I'm in the US, and I've applied to a pretty wide breadth of schools (36 ACT), some for math some for other stuff. i've taken calc BC, Calc iii at a nearby community college and am currently taking an intro to analysis course, when it comes to math, my options are between honors programs at a few flagship state schools and a very well respected liberal arts college, Grinnell. A small school with close access to professors is ideal for me, but looking at grinnells math curriculum I can't quite tell if their course offerings are limited --- what topics is one supposed to come out of a math major with a knowledge of?
Does anyone know how to reconnect with family ?

"How to test whether one knows Analysis? The answer is to test whether he knows Fourier Analysis.
How to test whether one knows Algebras? The answer is to test whether he knows Tensor Product." -- professor Zhu Yongchang
yet another ust personality
what do you want to do with your math degree?
the course offerings do look quite limited - there seem to be a couple rotating topics course so the advanced material is there, but its intermittent and not really in high quantity (you'd be able to take like 1 or 2 a semester in your upper years)
if your goal is graduate school in mathematics i would consider it (sadly) insufficient
but if your goal is to earn a bachelors while getting a bit of exposure to advanced topics in the process, then it seems fine
my main concern is that the actual pathway to interesting mathematics seems really slow logistically
calc 1 → calc 2 → linear algebra → intro proofs all have to be taken before any real analysis/abstract algebra
and thats a prereq chain so 1 semester each
that means that you'll only start to see introductions to specialist topics in your 3rd year
idk if theres ways to speed that path up though, a lot of schools offer alternate pathways for math majors
im just looking at the course catalogue
and for a math major you'd be spending 2 years doing "the math everyone takes" before getting into "the math a math major learns"
which is just super slow (and boring IMO)

What do you guys do for fun in math class when you finish your work (no phone)
cook food
no it’s harry potter
sleep
when i was in high school and the teacher wouldn't let me go on my phone or play on whatever handheld game console i'd just sleep
i just slept for 8 hours
after averaging 5 hours during the week
sometimes i'd do the homework for other classes too
i did other math for fun in math class
instead of my homework 
probably wouldn’t have gotten a C in multivar calc if i did hw
other homework, read a book, stare out the window idk
at some point i just started going home
because i lived close to the school

We don't have work in class. its just lectures
lol my bros I’m in high school and you guys all know about what happens in college
You die
What?

we cease living
That looks like Deltoid behavior as well 
lol
During high school?
If the class gets boring I just move out to the last row feigning like I'm very focused in the class while in reality I was just reading off from my complex analysis book 
If I cared enough about my English teacher's weird ideologies and his bizarre political views that would make him get arrested so easily I wouldn't end up with a D in English I think
I didn't really do math in high school
I hated it so much
Top 1 hated subject lol
I either went scrolling over insta or leave the class
so what made you change your mind?
Mathcord and Deltoid
why'd you join mathcord?
For homework
have you ever had teachers that are good at teaching math?
I see
that means you went from hating math to doing AnaNT in less than a year though
very impressive
I had one that kept talking about how badly he's getting paid when he was getting paid the most
I still can't do anaNT properly
oh
I'm lacking a lot of prereqs
you're certainly learning faster than I am lmao
what is AnaNT
analytic number theory
Idk about that tbh
But yeah I think I could be learning way slower if I was attending an university

if this was a question directed generally, then the answer would be a resounding yes for me
you're lucky
I've been lucky enough to have many, many good teachers in my life
not just for math
i never had as most of my math teachers are ok/bad at teaching
yet here I am, still being an idiot
i did a lot of self-study
self-study is good
my teachers were all well-motivated and good explainers
I got very lucky 
I had a teacher from Waterloo. He was the absolute worst teacher ever
I wonder if your experience (and Deltoid's) is widespread around canada
̶s̶a̶m̶e̶
I don't know how lucky I got because I haven't really known much else 
What is with UWaterloo
lmao
when i took a philosophy class i never expected that it would be a memorization class
I was disappointed

ill make sure to be a better waterloo teacher for you guys
Are you becoming a professor
I don't want to become a teacher even though I like the idea of teaching
i would be more interested in teaching if it was 40 years earlier heh
At my uni, grad students are required to teach UG courses for example Calc 1 and Calc 2, maybe that
I think that’s required basically everywhere
Yeah it is
the prior discussion was about high school teachers though
I don't want to teach students who are probably disinterested in math tho
I mean, no one does
Should I do a degree switch to chemistry?
Then the answer is obvious:
Yes.
You'll make more money that way
depends on what you're switching from 😁
Oppenheimer majored in chemistry, right?
@surreal bison What are you studying?
Representation Theory (of semisimple lie algebras, probably will add in compact lie groups at the end)
Riemannian Geometry
i'll either pick back up and do the second half of hatcher's algebraic topology, the rest of the Galois theory in Lang along with the commutative algebra, the modules section of Lang, the second half of Conway's textbook on complex analysis, or perhaps something else
Oh cool.
Just wondering, I see you active all over lol
Makes sense!
I'm still undergrad, but I know I want to work in either digital signal processing or statistics, and intend to go to grad school for one of those. I still got a couple of years to decide.
Right now I'm just exploring everything
Trying to get through a bunch of Set Theory topics and texts and then hopefully never have to deal with it again, but I feel the background in it is useful just for personal knowledge.
I'm also still undergrad
It is just that I think that me reading graduate textbooks probably counts as "beyond a typical undergraduate mathematics degree*.
I would never actually describe myself as a post grad, or even as doing post graduate mathematics (which to me sounds like doing research level mathematics, as opposed to merely intro grad level)
Yeah they are talking about readjusting the roles a bit
Graduate textbooks have the good stuff
After this set theory phase I need to dive back into Lang 
Welp, I wonder when I could become grad level
Maybe after I published several papers? Idk
our process is kinda flawed since we ask people "what math do you do" and if someone says "numerical analysis" (or like, almost any other applied subject) we have no clue whether that means undergrad or grad level applied math
since the terms used here are broad and are used for everything from "a doctor who has spent the last 30 years of my life doing research on this" to "an engineering student who was assigned reading in their math methods 101 class"
at least for pure math its fairly easy to distinguish someone talking about "calculus" from someone talking about "stochastic calculus"
or "polynomials" from "algebraic geometry"
this is why we ask for examples of papers/textbooks theyve read recently
but we still cant claim to be able to judge everything 100% perfectly
if you're thinking of chemical engineering, you can make 6 figures
however according to the u.s. bureau of statistics, there are x10 more people employed in electrical engineer / mechanical engineer jobs than chemical engineer
whether the low employment numbers is due to low graduates or low job opportunities is something to be considered
i believe there could be better job opportunities elsewhere
Not in the US, but I was always told in school that chemical engineering is rough. Apparently there just isn’t that many jobs going and you’re quite specialised so I think it is probably the job opportunities issue
Equally though like MechEng and EE are some of the most employable degrees full stop. I think after medicine they might actually be the most employable (in the UK at least)
So most things will pale in comparison to those. But ChemEng being hard to find jobs in is definitely something I have been told

Hello randos
a pour inverse
K'=λ(x0x1x2x3x4x5x6)(x0x3(Wx4)x5)
De manière plus générale soit:
W'=λ(x0 … xn) (x0∗∗(K1 xf(1))∗∗(K2 xf(2))∗∗ … ∗∗(Kn xf(n))∗∗)
où ∗∗ représente des termes quelconques ou des variables dupliquées et où les Ki sont des termes inversibles à gauche admet comme inverse à droite:
K'=λ(x0 x1 … xp) (x0(WG(1) xG(1)) (WG(2) xG(2))…(WG(n) xG(n)))
où p est le nombre total de termes de W', Wi un inverse à droite de Ki et où G désigne la fonction définie précédemment.
On constate donc que la recherche des termes inversibles à droite suppose connus les termes inversibles à gauche. Or l'exemple K' ci-dessus est inversible à gauche et utilise des termes inversibles à droite. Il apparait ainsi que la caractérisation de ces termes ne peut se faire indépendamment les uns des autres dans ce contexte .
L'étude des termes inversibles à gauche est plus délicate. Il est cependant facile d'établir que: Tout permutateur-projecteur régulier admet un inverse à gauche.
Tous les exemples d'inverses à gauche qu'on a donnés dans ce chapitre sont réguliers et n'admettent pas d'inverse à gauche sans l'extensionalité. Dans les théories sans extensionalité les termes inversibles à gauche ne sont pas réguliers à part I. On peut se demander s'il existe des termes inversibles à gauche avec usage de la règle d'extensionalité et qui ne sont pas réguliers. En voici un exemple:
K'=λ(x0 x1 x2) (x1 (x0 x2))
qui n'est pas régulier et pas inversible à gauche sans l'extensionalité admet ici comme inverse à gauche
W'=λ(x0 x1) (x0 I x1)
On peut donner maintenant une classe assez grosse de termes inversibles. Soit D0 l'ensemble des expressions de la forme
λ(x0 x1 … xn) (x0 X1 X2 … Xp)
où les Xi sont des termes ou des variables quelconques tels que n d'entr'eux représentent une permutation des variables x1 … xn. D0 est une classe de termes inversibles à droite. Soit G0 l'ensemble des expressions inversibles à gauche sans l'extensionalité. Définissons deux suites d'ensembles (Di)i∈ N et (Gi)i∈ N.
L'ensemble Di+1 contient les termes de la forme:
λ(x0 x1 … xp) (x0∗∗(K1 xf(1))∗∗(K2 xf(2))∗∗ … ∗∗(Kp xf(p))∗∗)
sachant que f est une permutation de {1,2,…,p} et que Kj est élément de Gi.
L'ensemble Gi+1 contient les termes de la forme:
λ(x0 x1 … xq) (x0 (W1 xg(1)) (W2 xg(2)) … (Wk xg(k)))
sachant que g est une injection de {1,2,…,q} dans lui-même et que Wj est élément de Di. Alors:
∪
i ∈ N
Di
est une classe de termes inversibles à droite et
∪
i ∈ N
Gi
est une classe de termes inversibles à gauche. Malheureusement ces classes ne caractérisent pas complètement les termes inversibles qui nous intéressent puisque l'exemple précédent n'en fait pas partie ainsi que l'exemple suivant:
K'=λ(x0 x1 x2) (x1 (x0 (W x2)))
a pour inverse à gauche
W'=λ(x0 x1) (x0 I (K x1))
car
W'(K' x0) x1 = K' x0 I (K x1)
= I (x0 (W (K x1)))
= x0 (B W K x1)
= x0 (I x1)
= x0 x1
